Abstract
It is necessary to recover or detritiate tritiated species that are extensively coexistent in nuclear fusion
installations. A conventional way to recover tritium release to atmosphere is catalytic oxidation of tritiated species andadsorption of tritated water vapor on adsorbents with high surface areas. However, pressure loss would become more
serious with increase in the size of adsorbent beds, which could lead to greater power needs. Therefore, new adsorbents
with low pressure loss and surface areas need to be developed and utilized for such large-scale adsorption systems.
Thus, the authors tested new types of adsorbents, which are gear-type and honeycomb-type pellet adsorbents.
It was found that the gear-type pellet adsorbents have larger adsorption capacity than the honeycomb-type pellet
adsorbent. Furthermore, it was also found that the gear-type MS4A adsorbent possesses larger adsorption capacity thanother adsorbents tested in this work. Among the new adsorbents studied in this work, the gear-type MS4A adsorbent
appears to be most promising for the application to the adsorption systems in terms of adsorption capacity andadsorption rate.

1. Introduction
A large amount of tritium would be handled asfuel in nuclear fusion power plants. Tritium is theradioisotope of protium, and is easily taken into
human body. Thus the behavior of tritium
accidentally released in fusion power plants should
be studied for the safety design and radioprotectionof workers. For this reason, recovery or detritiationof tritiated species is indispensable. A fusion researchfacility and a power plant will be require a large
detritiation system to prevent the tritium release andto recover the tirtiated water vapor. Tritium released
should be recovered as efficiently as possible. A
conventional way is to oxidize tritiated species andmake them be adsorbed on adsorbents with highsurface areas. Thus, reliable adsorption systems oftiritiated water vapor are required, which would belarge-scale adsorption systems. Some studies havebeen done for this purpose(1),(2). However, pressure
loss would become more serious with increase in thesize of adsorption beds, which could lead to greater
power needs with regard to blowers, pumps and soforth. The adsorbents used in the system need to

In this study, attention was focused on new
adsorbents, which are gear-type pellet MS5A

adsorption characteristics of the new adsorbent werecomparatively studied with conventional type ofadsorbents (pellet-type MS5A adsorbent, pebble-type

Experimental

Adsorbent

In this work, new adsorbents such as gear-typepellet adsorbents and honeycomb-type pellet
adsorbent. These are produced by Nagamine
Manufacturing Corporation, of which major
component is zeolite-5A or zeolite-4A. The
photographic views of the adsorbents are shown in
Fig.1. As shown in Fig.1 (a) and (b), appearance ofthe gear-type pellet adsorbents (both of zeolite-5Aand zeolite-4A are produced) is like small gear
wheels, which could result in greater surface areas tobe contacted with process gases including water
vapor. According to information given by the
manufacturer, pressure loss of the bed packed with
gear-type pellet adsorbents is smaller than that of

usual pellet-type adsorbents. Figure 1 (c) shows thephotographic views of honeycomb-type pellet
adsorbent (zeolite-5A), indicating that appearance ofthe honeycomb-type pellet adsorbent is just as
honeycomb-type adsorbents. However, the adsorbent
is not used as usual honeycomb stacks but used as(c)packed beds, which could result in greater surface
areas to be contacted with process gases including
water vapor. According to information given by the
manufacturer, pressure loss of the bed packed withhoneycomb-type pellet adsorbents is also smaller
than that of usual pellet-type adsorbents.
Advancement in manufacturing technology has
enabled manufacturing of the above adsorbents withcomplicated shapes.
For comparison, the authors also examined twoconventional pellet-type (Molecular Sieves 5A)
adsorbents and pebble-type (Molecular Sieves 5A)
adsorbents, manufactured by UNION-SHOWA Co.
and ALDRICH Inc., respectively. The average sizesof pellet-type and pebble-type adsorbents were 3 mm()ൈ 7 mm (length) and 3 mm (), respectively. The
photographic views of the pellet-type and thepebble-type adsorbents are shown in Fig.2.

Water adsorption
The experiments were conducted by thebreakthrough method, in terms of adsorption capacity
and adsorption rate. Figure 3 shows a flow diagramof the experimental apparatus used in this study.
Sample adsorbents were packed in a tubular reactor
made of quartz, and water adsorption experiments
were carried out using fixed beds of the adsorbents.
The adsorbents were dried under the flow of dry Ar
gas at 350 °∁ for 8 h and water vapor adsorbed wasdesorbed from the adsorbents in each experiment.
H2/Ar gases were first passed through the cold trap
packed with a molecular sieves 3A adsorbent dippedin ice water at 273K to remove water vapor
contained in mixture gases supplied from gas
cylinders. Then, water vapor (converted from H2 to
H2O completely) was generated in the mixture gases
by introducing the H2/Ar mixture gases to a copperoxide bed held at the temperature of 623 K. Then, theH2O/Ar gases generated with the CuO bed werepassed through the sample bed (packed with theadsorbents), of which temperature was maintained atexperimental temperatures (283K, 303K, 323K) witha constant-temperature water bath. The water vapor
concentrations in the process gas (Ar) were measured
with a hygrometer. Breakthrough curves obtained inthis way were analyzed, and the amounts of adsorbed
water or adsorption rates were discussed.

partial pressure of water vapor. The adsorption
amounts of water on the adsorbents were investigatedin the partial pressure range of 10-1000 Pa. The
experimental results indicate that the adsorption
capacity of water on the honeycomb-type adsorbent
is lower than that of the gear-type adsorbents, while
the gear-type 4A adsorbent possesses the highest
adsorption capacity among the adsorbents tested inthis work. The content of zeolite 5A was 70% in thegear-type 5A and honeycomb-type adsorbents, but it
was 80% in the gear-type 4A adsorbent. This isprobably a chief reason for greater adsorption
capacity of the gear-type 4A adsorbent. Therefore, interms of adsorption capacity, the gear-type 4A
adsorbent could be also used as an adsorbent for
adsorption of water like zeolite 5A-based adsorbents
that are usually used for adsorption systems in thefusion reactor facility. The effect of pore size
attributed to the zeolite structure on the adsorption
capacity of water appears to be small.

Analysis of experimental adsorption
isotherms for adsorbents
The authors analyzed the adsorption isothermsof water vapor on the gear-type 5A, gear-type 4A,
and honeycomb-type 5A adsorbents at thetemperatures of 283, 303 and 323K. First, theLangmuir model was tested for correlation of theisotherm. The result of correlation is also shown aslines in Fig.5, which indicates that Langmuir
equation cannot properly reproduce the experimental
isotherm data. Therefore, other adsorption isotherm
models were tested for correlation of theexperimental isotherms. Then, the authors tested theLangmuir-Freundlich (L-F) equation, which isexpressed as:

The results of correlation with the above equations
are shown in Fig.6 The Langmuir-Freundlich
equation rather well reproduced the experimental
isotherms on the gear-type 4A or 5A
honeycomb-type adsorbents in spite of its
mathematical simplicity. However, experimental
isotherms of the gear-type 5A adsorbent could not beproperly reproduced. Thus, the authors tested more
complicated model that can be called a 2-site
Langmuir-Freaundlich equation:(c)

Figure 7 shows the results of correlation of theexperimental isotherms obtained by using the 2-site
Langmuir-Freundlich equation, which suggests thatthe 2-site Langmuir-Freundlich equation better
correlates the experimental isotherms.
3.3

Breakthrough profiles
Adsorption performance for the water vapor was
also investigated by observing the breakthroughbehavior. Figure 8 compares the breakthrough curves
for a water vapor adsorption on gear-type,honeycomb-type, pellet-type and pebble-type
adsorbent with the almost same size (3 mm). The
break through curves indicate that the adsorption
capacities (based on the bed volume) of water vaporof the new types of adsorbents are smaller thanconventional adsorbents. The breakthrough period on
gear-type and honeycomb-type adsorbent (300-500min) is shorter than on cylinder-type and pebble-type
adsorbent (500-1000 min). This is because the bed
densities of the gear-type and honeycomb-type
adsorbents are smaller than that of conventionalpellet or pebble adsorbents.
Figure 9 compares breakthrough curves at theinitial stages of breakthrough for water vapor
adsorption on gear-type, pellet-type and pebble-type
adsorptions. The adsorption rates (represented by theslope of the breakthrough curves) of water vapor on
the pellet-type adsorbent appears to be greater thanthat of the gear-type and pebble-type adsorbents. The
breakthrough curves on the gear-type andpebble-type adsorbents at the initial stage of
breakthrough exhibit almost the same slops. As
mentioned above, the bulk bed densities of gear-type
and honeycomb-type are lower than that ofpellet-type and pebble-type adsorbents. Thus, it isconsidered that the adsorption capacities andadsorption rate for water vapor could be improved if
the higher bulk densities of gear-type andhoneycomb-type adsorbents are achieved by moreadvancement in fabrication technologies of such
adsorbents. The honeycomb-type adsorbent producedin the industry at the present stage is not as effective
as the gear-type adsorbents for adsorption of tritiatedwater vapor.
Figure 10 also compares the breakthroughcurves for water vapor adsorption on the gear-type
adsorbents containing 5A or 4A zeolite. This result
indicates that the gear-type 4A adsorbent offers ahigher adsorption rate than the gear-type 5A
adsorbent. One reason is possibly the difference inzeolite contents between the two adsorbents; thegear-type 4A adsorbent possesses higher water

adsorption capacity than the gear-type 5A adsorbent.
As mentioned above, the zeolite contents are 70% in
the gear-type 5A and 80% in gear-type 4A,
respectively. It seems that difference in micro-pore
sizes of 4A and 5A gives less effect on adsorption
rates.

Figure 11 shows the breakthrough curves forwater vapor adsorption on gear-type 4A at various
flow rates. As expected, breakthrough time isshortened with increasing flow rates of process gas.
In order to analyze these adsorption breakthroughcurves and to quantify adsorption rates, we are now

in the process of developing a numerical calculation
model. More detailed data on experimental
adsorption isotherms are necessary to more accurate
adsorption isotherm equations, as well.
4. Conclusion
To develop a high performance adsorbent
system for tritiated water vapor, the properties of new
types of adsorbents such as gear-type adsorbents andhoneycomb-type adsorbent were experimentallystudied and the results were summarized as follows:(1) Adsorption characteristics of gear-type andhoneycomb-type adsorbent were investigated by
the breakthrough method.
(2) Various adsorption models were tested tocorrelate the experimental isotherms. It is foundthat the Langmuir-Freundlich model could
properly correlate the experimental adsorption
isotherms.
(3) It was found that the adsorption capacity ofwater vapor on the gear-type adsorbents is

higher than that on a honeycomb-type
adsorbent.
(4) The experimental breakthrough curves indicatethat the adsorption rates of water vapor on
gear-type and honeycomb-type adsorbents are
smaller than that on conventional typeadsorbents. The reason is probably the smaller
bulk bed densities of the gear-type andhoneycomb-type adsorbents compared with theconventional pellet and pebble types ofadsorbents.

Numerical Simulation of Flow Field in Laminar
Waterjet-guided Laser Process

Hiroshi SUGAI***and Yasushi KOZUKI****
Abstract

The waterjet-guided laser processing is a thermal cutting process in which the waterjet acts as an
optical waveguide. The better design of the water chamber disk for generation of waterjet could lead tothe thin and appropriate laminar waterjet flow which offers the total reflection at its interface with air.
Analysis of the flow field in the chamber is critically important for controlling the laser system. A
numerical calculation code has been developed for more advanced laser process. The numerical model
developed in this work is based on two-dimensional cylindrical coordinate. As a result, typical flow
fields were numerically obtained and visualized. Moreover, test numerical calculations were performedby changing the water chamber size.

1. Introduction
The dry laser cutting is today used in various
industries, such as semiconductor, electronic, medical,
energy or automotive sector. However, the performanceof this conventional dry laser-cutting process has serious
disadvantages because of the following reasons:(1) The dry laser process leads to very high thermalload to the materials processed.
(2) The focused parallel laser beams generated in thesystem are divergent and the cutting position
should be controlled to the point with a great dealof precision.
(3) The assisting gas stream needs to remove theeroded materials with a limited pressure (max 20bars). Otherwise, the mechanical force on the workpiece would become too heavy.
For these reasons (drawback of dry laser cutting),
the waterjet-guided laser-cutting process has beendeveloped, in which a parallel beam is entirely confined.
This is similar in principle to an optical fiber. This cutting
machine could cool the substance, while removing themolten material and avoiding contamination fromvaporized gases.
For design and optimal operation of this process,understanding of the waterjet behavior is indispensable.
Thus, a numerical calculation code has been developed
for simulation of waterjet-guided laser cutting process.

The numerical calculation model is based on
two-dimensional cylindrical flows. Typical flow fields
were calculated and visualized. In this work, test
calculations were also performed by changing the size of
the water chamber.
2. Waterjet guided laser process
Figure 1 shows a visual image of the waterjet-guided
laser cutting process. It is a sort of hybrid method
combining a laser beam with a low-pressure water jet.
This cools the cut edges and provides effective removalof debris from the kerf. The low-pressure water jet,emitted from the nozzle, guides the laser beam by meansof total internal reflection at the-water/air interface, in amanner similar to conventional glass fibers. Therefore, it
has come to a “cold and clean laser”, which eliminates all
the known problems associated with dry laser, such as
thermal damage, contamination deformation, deposition,oxidation and micro-cracks. More details of the machine
are as follows:(1)Laser
Lasers used are flash lamp or diode pumped solidstate pulsed Nd:YAG lasers with pulse durations in the
micro- or nano-second range, operating at 1064 nm,532
nm, or 355 nm. Average laser power ranges from 10 W to
200 W.
(2)WaterPure deionised and filtered water, at low-pressure, areused. Because the jet is “hair thin”, the level of water
consumption is extremely low – in the order of 1 litre perhour at 300 bar pressure and the resulting forces exerted
are negligible(<0.1N).

Figure 1 shows a visual image of water jet ejectedfrom a nozzle. The nozzles range in diameter from 25 to100 μm and are made of sapphire or diamond, as thesematerials’ hardness enables generations of a long, stablereplacement. Figure 2 shows a photographic view of real
cutting scene. The cutting kerf width ranges from 27 to
100 μm, as a function of the nozzle size. The laser energy
is always guided to the bottom of the kerf. Figure 3 showsan actual photographic scene of water jet ejected cutting,suggesting that the cutting is carried out in a width of as
thin as 27 m (thinner than the diameter of hair).
3. Numerical simulation of flow field
The authors are in the process of developing acalculation program that estimates flow fields in thechamber of water-jet-guided laser cutting using
turbulence models.
Flow fields are calculated by solving theNavier-Stokes equations numerically. Together with ahigh Reynolds number k-ε model proposed by Launderand Spalding(1). The equations of continuity forincompressible fluids and the Navier-Stokes equation are
given as follows:(ﾑ ﾗr v ) = 0

These equations should be also solved numericallyin order to evaluate the turbulent viscosity. In this study,
the two-dimensional cylindrical coordinate (r-z) was usedin calculations. For the stability of numerical calculation,
the upwind scheme differential scheme was employed
and the effective viscosity meff (= m + mt ) was used for
mt in this work. In the case of steady state condition, theequation of continuity, the conservation of momentum

Result and discussion

The numerical calculation was first performed by
setting a chamber size of watejet-guided laser cutting
process with 10 mm (=D) ×0.4 mm (=H), which is a
representative configuration of the chamber used in thewatejet-guided laser cutting process. The volumetric flowrate of inlet and outlet streams of the chamber was 50
ml/min. Figure 3 shows a schematic view of the chamber.
The flow fields of water in the chamber were calculatedusing the 2-dimentional simulation program based on thestandard k-ε model shown as Eqs. (9) to (13). The
chamber system, in which a 5 mm × 0.4 mm rectangular
plain was cut out based on the cylindrical symmetry, wasFig.2 Photographic view of laser micro-jet cutting(Thinner than one piece of hair)Fig.3 Chamber size

partitioned into control volumes with 500 mesh in theradial direction and 40 mesh in the axial direction, andthe discretization was performed in the staggered meshprinciple to avoid chess board instability. The SIMPLE
method was used to obtain steady state flow fields, andmatrices generated in calculation were solved using the
TDMA technique. Figure 5 shows the flow fieldmagnified in terms of the exit region of the chamber (0 <r < 8ൈ10-5 m and 0 < z < 8ൈ10-5 m), which indicates thata water jet is successfully generated in the numericalcalculation; very high flow rates of the fluid in thevertical direction are seen close to the water jet exit of thechamber. This figure suggests that the flow lines
converge at the exit of the chamber and a water jet isformed. The distribution of the effective viscosity was
shown in Fig. 6, which reveals that the flow field of thealmost entire region is weak turbulent (the values of theeffective viscosity are approximately 0.001 Pas and thevalues are not so larger than the viscosity of water atambient temperature). It is also indicated that higher
effective viscosities are observed close to the center lineof the chamber. Figure 7 shows the distribution ofpressure in chamber as well.

Okawa et al. performed an experimental study on
visualization of inward flow between two parallel disks(2).
The size of their experimental apparatus (D = 600 mm
and H = 13 mm) is approximately 50 times larger than thesize of the chamber used for numerical simulation in thiswork, and their experimental apparatus was not fully
symmetric; the parallel disk was experimentally
simulated using /2 (angle) flabellate parallel plates toenable visualization of flow fields. Thus, directcomparison of the results of this study and their resultsappears to be difficult. However, their experimental
results suggest that the flow fields become laminar whenthe value of an acceleration parameter, KV (=H/(2Q)),
is greater than 3.0×10-5. The value of the acceleration
parameter in the operational condition of the water jetmachine in this work (KV =7.5×10-4) is greater than
3.0×10-5. Thus, a fully laminar flow field is expected if
the results reported by Okawa et al. is applicable to thesystem of this work.

Therefore, the authors next calculated the flow field
in a fully laminar regime. The transport equations of
turbulent energy and dissipation function were not solved,
and the value of turbulent viscosity, mt , was set to zero.

Numerical Simulation of Flow Field in Laminar Waterjet-guided Laser Process

Figure 8 (a) shows the flow field magnified in terms of
the exit region of the chamber (0 < r < 8ൈ10-5 m and 0 < z< 8ൈ10-5 m), which indicates that a water jet is
successfully generated in the numerical calculation
regardless of a laminar regime. This figure suggests thatthe flow lines converge at the exit of the chamber and a(a) H=0.4mm(b) H=0.8mm(c) H=1.6mm

13laminar water jet is formed. The results shown above
reveals that the numerical simulation can satisfactory
reproduce the laminar water jet, which is realized in theactual watejet-guided laser cutting process andindispensable for its stable operation.
Scale-up test calculations were also carried out, inwhich the height of the chamber was varied; in thesecases, the transport equations of turbulent energy anddissipation function were not solved and the value of
turbulent viscosity, mt , was set to zero, as well. One
calculation was performed by increasing the chamber sizeof the laser cutting machine to 10 mm (=D) × 0.8 mm(=H). The chamber system was partitioned into control
volumes with 500 mesh in the radial direction and 80
mesh in the axial direction. Figure 8 (b) shows the flow
field magnified in terms of the exit region of the chamber(0< r <8ൈ10-5 m and 0 < z < 8ൈ10-5 m), which indicatesthat a water jet is also successfully generated in thischamber geometry. This figure also suggests that the flowlines converge at the exit of the chamber and a water jet isformed.
Another numerical simulation was performed byincreasing the chamber size of the laser cutting machineto 10 mm (=D) × 1.6 mm (=H). The chamber system
was partitioned into control volumes with 500 mesh in
the radial direction and 160 mesh in the axial direction.
Fig. 8 (c) shows the flow field magnified in terms of theexit region of the chamber(0< r <8ൈ10-5 m and 0 < z <8ൈ10-5 m), which indicates that a water jet is also
successfully generated. This figure also suggests that theflow lines converge at the exit of the chamber and a water
jet is formed. The results shown above indicate thatchange in the height of the chamber is less influential ingeneration of laminar water jet.
5. Conclution
A numerical calculation code has been developed forthe process simulation of watejet-guided laser cutting
process. The numerical model developed was based on
two-dimensional cylindrical flows. As a result, typicalflow fields were calculation and visualized. The standardk- model was first tested in the numerical simulations,but it was found that laminar–regime numericalcalculations can reproduce the laminar water jet under the
standard operational condition of the water-guided laser
cutting machine. Furthermore, test numerical calculations
were performed by varying the water chamber size. In thesimulation, the thickness of chamber was doubled or
quadrupled. The results indicate that laminar water jet is
successfully formed at the exit of the chamber regardlessof difference in chamber configuration.

旨

従来型レーザー切断処理では、切断する物質によって制限が生じる。水ジェット誘導レーザー処理は、この制限を改善するとともに、熱的な弊害も抑えることが出来る可能性がある。本レーザー処理は、光ファイバーなどと共通する光学的波形制御を応用し、水ジェットによるレーザー伝搬を補強した切断処理方法である。水ジェットにより円盤状容器中には水の干渉作用により総合的な屈折、反射により、切断のために要するレーザーエネルギーを局所に収束することができる。このプロセスの設計を支援するために、
水ジェットの数値シミュレーションが、設計、プロセス解析、運転最適化のために必要不可欠になる。本
研究では、この目的のために使用される数値計算コードを開発した。開発された数値モデルは、2 次元円柱極座標流れに基き、本装置に用いられる水チェンバー内の流れ場を計算した。計算結果から、典型的な流れ場が、計算・視覚化された。また、チェンバーサイズを変化させ、そのときの流れ場を、数値計算コードを用いて解析した。

Mosquito Nets as Social Business in Bangladesh― A Case Study of BASF Grameen Ltd.―
Hiromi TSUBOI**
Abstract
The practice of using business methods to solve social problems has been accelerating in recent years. The
social business practices of Grameen Bank, its associated companies, and Grameen-related joint companies havebeen gaining a lot of attention. Their business model they practice is regarded as being a “social business.” In
Bangladesh, there are many Grameen-related joint companies operating as social businesses. BASF Grameen is oneof them.
This paper addresses the aforementioned company, BASF Grameen, and focuses on their mosquito net project,which is one of two social business projects that BASF Grameen is involved in. This study’s fieldwork was
conducted by the author in December 2012. The result of this fieldwork indicates that three points are important for
the future prosperity of BASF Grameen: (1) raising awareness among people regarding the value of BASF
Grameen’s mosquito nets; (2) reducing the price; and (3) introducing an installment payment option.

1. Introduction
The practice of using business methods to solve
social problems has become common in recent years.
The social business practices of Grameen Bank, its
associated companies, and Grameen-related jointcompanies have been gaining a lot of attention. Theirbusiness activities are commonly regarded as social
businesses.
The joint companies’ ventures are conducted basedon the business philosophy of Muhammad Yunus,
founder of Grameen Bank. His philosophy is represented
by the seven principles of social business(1) :1. The business objective is to overcome poverty,
or one more problems (such as education, health,technology access, and environment) thatthreaten people and society―not to maximize
profit.
2. The company will attain financial and economic
sustainability.
3. Investors get back only their investment amount.
No dividend is given beyond the return oforiginal investment.
4. When the investment amount is paid back, profit
stays with the company for expansion andimprovement.

5. The company will be environmentally conscious.
6. The workforce gets market wage with betterstandard working condition.
7. Do it with joy!!!
There are many Grameen-related joint companies
operating as social businesses in Bangladesh, such as
Grameen Danone Foods Ltd., Grameen Veolia Water
Ltd., Grameen Uniqlo Ltd., and Grameen Yukiguni
Maitake Ltd. BASF Grameen Ltd. (hereinafter BASF
Grameen) is also one of these social businesses. This
paper examines BASF Grameen, and focuses on thecompany’s mosquito net project, which is one of twosocial projects BASF Grameen is currently involved in.
2. The state of malaria in Bangladesh
Malaria is a mosquito-borne disease that causes
fever, headache, shivering, and vomiting. In severe cases,
these symptoms can progress to coma or, in the worst
case, death. The United Nations Millennium
Development Goals (2) set a target of reducing the spreadof malaria.
In 13 of Bangladesh’s 64 administrative districts,
malaria is endemic. Those districts are labelled (1) to (4)in Figure 1. They are (1) Kurigram District in Rangpur
Division, (2) Sherpur District, Mymensingh District, and16

Hiromi TSUBOINetrokona District in Dhaka Division, (3) Sunamganj
District, Sylhet District, Maulvibazar District, andHabiganj District in Syllet Division, (4) Khagrachari
District, Rangamati District, Chittagong District,
Bandarban District, and Cox’s Bazar District in
Chittagong Division. Malaria is a nationwide risk, but
deaths directly related to malaria have only beenreported in these areas.
According to the World Malaria Report 2008(4) , 72
percent of the Bangladeshi population is at risk ofmalaria. The risk of contracting the disease is thegreatest in remote forested areas bordering India and
Myanmar. The health infrastructure in these areas isinadequate and access to health care services is poor. In
2004, Artemisinin-based combination therapy (ACT)
was adopted by Bangladeshi government officials as thetreatment policy. However, the number of reported casesin 2005 and 2006 far exceeded the capacity fortreatment.
The Bangladesh government has received grants
from the Global Fund (5) to promote the use oflong-lasting
insecticidal
nets(LLINs)andinsecticide-treated nets (ITNs) in these areas. A
Bangladesh-based
international
development
organization called BRAC, which is an NGO, has also
been sponsored by the Global Fund and distributes
LLINs and ITNs.
Table 1 shows a 10-fold decrease of the number ofdeaths from 501 in 2005, to 47 in 2009. However, it
should be noted that these figures may not be accurate
because many hospitals and private facilities do not
diligently report malaria-deaths and the deaths of people
who do not reach health care services also go unreported.
Taking this into account, the actual figure is likely to bemuch larger(3) .
3. Overview of BASF Grameen
3.1 Establishment
BASF Grameen was established in Bangladesh as asocial business joint venture resulting from the merger
of BASF SE and Grameen Healthcare Trust on March 3,
2009 (7),(8),(9) . BASF is a leading chemical company.
Grameen Healthcare Trust, on the other hand, is a
non-profit organization founded by Muhammad Yunus
and recognized by Bangladesh’s Trust Act.
It was promised that BASF would invest €200,000($260,000) and contribute the funding for one million

multi-micronutrient sachets (MMS) and 100,000
mosquito nets, and that Grameen would contribute its
knowledge of Bangladesh’s market, distribution
structures, and networks (7),(8),(9) .

Social purpose
The social purpose of BASF Grameen is to improve
Bangladeshi people’s health and to provide business
opportunities for the poor who otherwise would not beable to build up a business without support(7),(8) .
3.3 Products
BASF Grameen utilized two existing products from
BASF’s portfolio: impregnated mosquito nets that
protect people from insect-borne diseases, and dietary
supplement sachets, referred to as multi-micronutrient

17

Mosquito Nets as Social Business in Bangladesh−A Case Study of BASF Grameen Ltd.−sachets (MMS), which contain vitamins and essential
micronutrients(7),(8),(9) .
In the initial stages, the MMS business focused onreaching large consumer outlets, such as schools, andcooperating with established distribution channels, suchas pharmacies (7),(8),(9) . In next stage of the program, theMMSs would be sold directly to the end user throughestablished Grameen networks(7),(8),(9) . Similarly, themosquito nets were sold in grocery stores andpharmacies in urban areas, while in rural areas they
too were sold via established Grameen networks (7),(8),(9) .
3.4 Mosquito net plant
The plant producing long-lasting insecticidal nets
(LLINs) (10) was opened on March 23, 2012. This plant islocated in Social Business Industrial Park in Sarabo,
Kashimpur, Gazipur (Figure 2). It is owned by Grameen
Fabrics & Fashions Ltd. The nets are coated with the
R , a BASF product. The nets
insecticide Fendona ○remain effective against mosquitoes for several years,
which can allow them to meet the World HealthOrganization (WHO) requirements for LLINs. The nets
retain their repellent properties for up to 20 washes.
However, this may vary due to how the owners maintainthem. The nets are sold under the brand-name“Auschorjo Moshori.”
3.5 Marketing
BASF Grameen now sources the nets from theabove plant, and markets them. Grameen Distribution
Ltd. also sells the nets through Grameen Marketing
Network (11) (Figure 3). The main sales area is Chittagong
Division (see Figure 1).
4. Field research results and analysis
This fieldwork was conducted by the author in
December 2012. The purpose of this research was toconfirm the present state of the mosquito net plant inSocial Business Industrial Park and to gather feedbackon the nets from the end users.
4.1 Operation of the mosquito net plant
Figure 4 shows the process for manufacturing thenets: (1) the net is coated with the insecticide
R ; (2) the net is sewed; (3) the net is inspected;
Fendona○(4) the net is packed; and (5) the net is placed in awarehouse. A barcode tag is sewed on every net tocontrol the distribution of the net. The nets on sale aredyed in five colors: blue, green, white, orange, and pink.

available, and the retail prices are from Tk.550 ($6) toTk.650 ($7). Since non-insecticide treated nets are soldfor Tk.200, which is the minimum price at the market,
the poorest of the poor are less likely to be able to afford
to buy a net sold by BASF Grameen and Grameen
Distribution Ltd.

The first end user’s feedback
The interview with the first end user of a mosquito
net provided by BASF Grameen was carried out at Gori
Raunar Chala in Tangail in December 2012. Theinterviewee is Rotipa, a Grameen Bank member with 18
years’ experience. She is in the position of center chiefat present. She runs a salt business and room-letting
business. Her statement is as follows:
My village, Gori Raunar Chala in Tangail is anupland village, where the malaria incidence rate ishigher. BASF Grameen chose my village as a pilot area
and conducted a market research three years ago.
I was the first end user of a mosquito net BASF
Grameen supplied. The banker of Grameen Bank
recommended the net to me. He said, “It is a long lasting
insecticidal mosquito net, whose technology comes from
Germany.” I did not care about the technology, but theprice was Tk.450, which was reasonable for not only me
but also other villagers.
When I bought a net, there was a user’s manual
printed on a piece of paper in the package. This way wasvery inconvenient for me, because I could not know how
to use a net before opening the package. So I told myfirst impression to the banker. (The user’s manual isprinted on the package at present.)
One day I saw a few mosquitoes die inside the net.
Then, I understood the effect of the insecticidal net. But
I will give the price priority over the quality if I buy a
new one.

(2) Sewing(3) Inspection(4) Packaging

Judging from the prior statement, it could beassumed that it takes some time for villagers tounderstand the value of insecticidal nets, and that theprice takes priority over quality. Therefore, these twopoints suggest the importance of making the effect ofinsecticidal nets known widely among village people,
and making the price lower.

5. Conclusion
As of now, no universal approach to tackling theissue of malaria has been developed, because malaria
treatments and prevention methods differ from country
to country. In Bangladesh, appropriate treatments arelacking and medicine is costly for the poor. In addition,
irrigation ditches, drains, and other places that collectwater are not adequately maintained, and the use of DDT,

Mosquito Nets as Social Business in Bangladesh−A Case Study of BASF Grameen Ltd.−an insecticide, is banned. Under these conditions, amosquito net can be said to be the best solution.
BASF Grameen is not a charity but a business.
Therefore, BASF Grameen does not promote nets via
social marketing like a national voucher scheme whichbrings subsidized nets to the poor(13) , nor does thiscompany participate in a National Malaria Control
Programme in Bangladesh supported by the Global Fundso far.
BASF Grameen has created new jobs for the local
people and cooperated in reducing the number ofmosquitoes. However, the upfront cost of an LLIN is toohigh for the poor, even though the net lasts longer than a
non-LLIN. Moreover, the beneficial effects of LLINs are
not well understood among the people.
Necessarily, it is indicated that three points areimportant for the future prosperity of BASF Grameen:(1) raise awareness among people regarding the value of
Auschorjo Moshori; (2) reduce the retail price; and (3)introduce an installment payment option.

Abstract

The radiation characteristics of a leaky-wave antenna (LWA) consisting of a dielectric slab guideloaded with periodic metal strips on magnetized solid-state plasma were analytically studied by theoreticalanalysis and the finite-difference time-domain (FDTD) method in the millimeter-wavelength range. The
magnetic field and geometry dependences of the propagation characteristics of the LWA transmission line
were demonstrated using the results of the theoretical analysis to obtain the design concept. The results of
the FDTD analysis indicated that the radiation of our LWA can be scanned over an angle of about 50° withan externally applied transverse magnetic field.

研究報告- The Language “Noticing” Hypothesis –Towards Effective Teaching Methods in Japan
Kolawole Waziri OLAGBOYEGA**
Abstract
This paper is a contribution to a continued exploration of what Language “Noticing” Hypothesis has to offer the
language teachers and learners in Japan. The paper explores the hypothesis and examines the effectiveness of the method
in an EFL context such as Japan. Debates on language teaching methods tend to fall into oppositional views. Since theearly ages of English Language Teaching in Japan, yakudoku (grammar-translation) method has been the “vogue”. The
method, on the other hand, has been criticized in the last 20 years for failing to produce learners with high level ofproficiency in English. The criticism often leads to a demand for more emphasis on “output” or “communicative
language teaching” (CLT). Reviewing the previous research on input and output, some scholars suggest that output isnecessary for language acquisition (e.g. Swain’s ‘Output Hypothesis’) while some claim that language acquisition occurs
only through input (e.g. Krashen’s ‘Input Hypothesis’). However, some recent approaches try to link input with output ina dynamic mechanism of second language acquisition by adapting the factors of ‘noticing’, which is theorised as‘Noticing Hypothesis’ by R. Schmidt. The factors are also related to ‘implicit teaching’ and ‘explicit teaching’ inlanguage classrooms. This paper outlines Schmidt’s hypothesis about noticing and explores how the hypothesis could be
adapted to the real teaching contexts. The paper concludes that input/output and implicity/explicity should not be
discussed as opposites but should be seen as complementary teaching approaches.

Moreover, noticing can occur in both implicit teaching and

of the same structure. When the teacher explicitly shows therule before he/she gives examples, the learner would pay
attention to the target form.
Consequently, Noticing Hypothesis has stimulated theeffective collaboration of input and output or of implicit
teaching and explicit teaching.
As stated above, this language teaching hypothesis wasaresponseto

Krashen’s“comprehensible

input

hypotheses”(17). To do justice to this paper, let us consider
Krashen’s arguments.
3.

“Comprehensible Input”

Stephen Krashen’s “Monitor Model” is the best known
model of second language acquisition influenced by Noam
Chomski’s innatist theory of first language acquisition(18).
There are five basic hypotheses in this model: theAcquisition-Learning Hypothesis, the Monitor Hypothesis,
the Natural Order Hypothesis, the Comprehensible Input
Hypothesis, and the Affective Filter Hypothesis.
The Comprehensible Input Hypothesis, one of the fivehypotheses above, is based on the principle that language
acquisition occurs when one is exposed to language almost
all of which is comprehensible. Learners learn a new
language when they receive input that is just a little moredifficult than what they can easily understand. Krashen
defines a learner’s current state of knowledge as “i” and thenext stage as “1” thereby arriving at the formula “i+1”(19).
In support of Krashen’s hypotheses, Paul Nation(20) assertsthat there should be no more than one unknown word inevery fifty running words. In other words, there should be
more than ninety-eight percent familiar words in the text sothat meaning-focused input will occur. If more than five
percent of the running words are unfamiliar, then it is nolonger likely to be meaning-focused learning because somuch of the learner’s attention has to be given to language
features(21). Thus, the basic principle of the Comprehensible
Input Hypothesis is that students may understand most, but

4. Classroom Activities for Comprehensible Input
In second language acquisition, there are two types oflearning; form-focused learning and meaning-focusedlearning. In Japan, in traditional educational approaches
such as grammar-translation method (yakudoku), the focus
has been more on form than on meaning, which has often
been severely criticized for not having succeeded in
producing successful learners who can communicate inEnglish language fluently with other “expert users”(22) ofEnglish. Recently, communicative language teaching (CLT)
has gained more advocates(23), and at the same time,
importance of meaning-focused learning has been moreemphasized. On the other hand, how and what kind ofactivities should be implemented in language learningclassrooms should be different depending on the ‘learners’
characteristics’ and the ‘learning conditions’(24). Here are
four examples of activities for comprehensive input which
focus more on meaning than on form; appropriate forintermediate English learners in high schools in Japan.
4.1. Word definition
One of the traditional ways of learning new words in
EFL classes is directly translating the words of the target
language (TL: English) into the learner’s first language (L1:
Nihongo) and vice versa. However, the focus in this process
is mainly on form. After the learners have understood themeaning of the new words both in the TL and in their L1,
the teacher then provides the definition of the words in the
TL. The definition should be given in the words that arecomprehensible to the learners. Then learners think of themeanings of the new words in the TL. For example, if‘refrigerator’ is a new word, the learners understand it as‘reizouko’ in Japanese. Then the teacher provides thedefinition: ‘a metal container with a door in which food anddrink are kept cold so that it stays fresh.’ The word‘container’ may be unknown to the students; however, they

can guess the entire meaning that the definition is trying toreaders is that students encounter a reasonable number ofconvey, and connect it to the target word. In order to create

around 98 percent of the vocabulary. Examples of activities
for this strand are extensive reading and listening tolectures. Second, as for meaning-focused output, learners
should be encouraged to produce meaningful words throughspeaking and writing. Examples of activities for this strand
are taking part in conversation and writing about what has
just been read. Third, as for language-focused learning,deliberate attention to vocabulary and other language
features are needed, although too much attention to form is
not desirable. Examples of activities for this strand are
vocabulary exercises and intensive reading. And fourth, as
for fluency development, learners should be fluent in using
what they already know in each of the four skills oflistening, speaking, reading, and writing. Examples ofactivities for this strand are speed reading with easy texts
and repeated listening/reading. All of these four strands
should be well balanced in a second language acquisition(SLA) curriculum.
It is important to ensure that the learners receive a large
amount of comprehensible input. On the other hand, nomatter how much input learners are given, the Affective

Implications for English language teaching inJapanA teaching method significantly developed by Noticing
Hypothesis is ‘focus on form’ instruction or ‘form-focused’
instruction. It can be defined as the “inversion in which
simultaneous attention is brought to both meaning and howthat meaning is encoded”(28). Here we look at anotherexample of this type of method applied in an English
teaching context. Suppose this is a typical English
classroom at a Japanese senior high school: 35 EFL
students all of whom are Japanese and use Japanese as theirfirst language, intermediate-level, and using a MEXTapproved textbook. In this lesson, the students are to learn
the structures of “It takes/costs... to do~” to talk about how
long it takes and how much it costs to do something.
At the beginning of the lesson, the teacher briefly
explains the structures to students by telling them about thebest place he has ever visited. Next, the students are asked
to think of the best places they have ever visited or where
many tourists visit in their area. They are, then, required towrite a paragraph in English to describe their travelling or
the place they would recommend someone to visit. The
teacher reads the students’ work and picks up errors to becorrected which are commonly made amongst the students.
For example, some students may miss “–s” in “takes” and“costs”, and some might say “It costed each of us 500 yen
to enter the museum” in writing about their school trip of
the previous year.
The explicit introduction of the target grammar as the
input will help the students to notice the key structure “Ittakes/costs... to do~”. When they work on the writing
activity as output, the students would be paying attention toboth the form and contents of their work by themselvesbecause they know that the paragraph is expected to be as

Noticing Hypothesis. It can be implicit or explicit andenables a learner to check and notice his/her interlanguage.
Let us see some examples in Saville-Troike(29). When alearner says “I can’t assist class.” meaning “I can’t attend
class.”, the teacher may respond “You can’t what?”meaning “You’ve got the wrong word. Try again.” Thismethod is referred to as ‘confirmation check’. Anothercommon form of feedback is ‘recasting’. When a learnersays “John goed to town yesterday.” the teacher may
respond “Oh, John WENT shopping. Did you go with him?”by paraphrasing the learner’s utterance and emphasizing thecorrect form. Again the important function of giving
feedback is that a learner can consciously review his/her
knowledge of the target language and revise it if necessary.
Various types of corrective feedback in the classroom are
explained by Lightbown & Spada(30).

Abstract
In this paper, when the speed control of a DC motor through wireless IP networks is done, the influences on thesystem affected by varying time delays over the networks are examined. Because wireless networks have morevarying delays than wired ones, we study the performance degradation. As a result of the experiment, it is foundthat the obtained step responses are different slightly.
