CALL, Self-access, and Autonomous Learning
Authors: Benavides Jorge E
Published: October 2018

The idea of autonomous learning through a process of self-access learning is a very powerful one since CALL (Computer-Assisted Language Learning) can provide environments which could cope with a large variety of learning possibilities and learning styles. The autonomous computer user is free to choose his own course, topics, and work at his own pace. However, in this approach, high motivation may not necessarily mean learning efficiently. The student may not be very good at selecting his own learning strategy, especially at initial stages. This problem could be alleviated if the introduction of learning autonomy, through self-access learning, is done as a process where the learner is being trained to progressively go from an externally-directed-learning approach to a self-directed learning approach.
Thinking Allowed: Reforming Indicator-Based Accountability to Enhance Innovation
Authors: Van Dooren Wouter , Willems Tom
Published: October 2018

NPM- flavoured accountability regimes in many instances stifle innovation rather than foster it. Today, New Public Governance (NPG) creates new challenges for indicator-based accountability systems. NPG raises questions on how to reform indicator-based accountability to make it work in complex multi- actor settings. What is the use of performance indicators when dealing with unruly problems? How to stimulate innovation without calling accountabil- ity in itself into question? This chapter proposes some prospective directions based on a critical analysis of indicator-based accountability.

No evidence of the effect of cognitive load on self-paced cycling performance
Authors: Holgado Darias , Zabala Mikel , Sanabria Daniel
Published: October 2018

Objectives: to test the hypothesis that cognitive load (low vs. high load) during a 20 min self-paced cycling exercise affects physical performance.Design: A pre-registered (https://osf.io/qept5/), randomized, within-subject design experiment.Methods: 28 trained and experienced male cyclists completed a 20 min self-paced cycling time-trial exercise in two separate sessions, corresponding to two working memory load conditions: 1-back or 2-back. We measured power output, heart rate, RPE and mental fatigue.Results: Bayes analyses revealed extreme evidence for the 2-back task being more demanding than the 1-back task, both in terms of accuracy (BF10 = 4490) and reaction time (BF =1316). The data only showed anecdotal evidence for the alternative hypothesis for the power output (BF10= 1.52), moderate evidence for the null hypothesis for the heart rate (BF10 = 0.172), anecdotal evidence for RPE (BF10 = 0.72) and anecdotal evidence for mental fatigue (BF10 = 0.588).Conclusions: Our data seem to challenge the idea that self-paced exercise is regulated by top-down processing, given that we did not show clear evidence of exercise impairment (at the physical, physiological and subjective levels) in the high cognitive load condition task with respect to the low working memory load condition. The involvement of top-down processing in self-pacing the physical effort, however, cannot be totally discarded. Factors like the duration of the physical and cognitive tasks, the potential influence of dual-tasking, and the participants’ level of expertise, should be taken into account in future attempts to investigate the role of top-down processing in self-pace exercise
Socio economic impact of undeclared blockade of India on Nepal
Authors: Pant Bhuwaneswor
Published: October 2018

Indian unofficial or undeclared blocked was a terrible move. It was a move on the part of Indian diplomacy. India imposed it, it was very transparent but not acceptable. Diplomacy is getting thing done without speaking or telling nastiest words in nicest manner. What had happened in southern border of Nepal? What was Indian's role? The study attempts to find out the reason of undeclared blocked of 2015 and identify the socio economic impact of this blocked imposed during the dark days of great earthquake in Nepal. Can a neighbor do so? India did it but did not speak a single word. The study has been conducted to analyze the impacts of the issue. Library method and comparative review methods were applied to analyze the impacts it had on Nepal. They tried to minimize the Chinese Communists influences but the move was wrong. So, Nepalese citizens cast their vote to elect communist parties with full majority. Indian policy was concentrated on causing instability in Nepal. Nepalese diplomacy proved to be ineffective to put pressure on Indian government for amending the Sugauli Treaty and the Treaty of 1950 as well as addressing controversy over Kalapani, Susta and Lipulek. At the time of election, all the political parties raised the issue against India as KP Oli did and successfully won the election. The pain of blockade is not forgotten in the name of improving bilateral relations.Research Nepal Journal of Development Studies Vol.1(1) 2018 18-27

Authors: Shrestha Kiran
Published: October 2018

Cardamom production is a potential cash crop of Kavre district. Many farmers were found to grow cardamom following traditional pattern. Women's participation in Cardamom production in Kavre is satisfactory and their roles are vital in the farm and market management. To check the status of cardamom production and women's role in Kavre, the researcher visited the District Agriculture Office and used snowball sampling technique to collect the primary data. For the secondary data, library method has been applied. Although the production and women's participation are highly encouraging, the farmers are reluctant to invest and produce cardamom at large scale. The study has found that the farmers need the entrepreneurship training, support and empowerment for mass production of cardamom. The future of cardamom production is bright in Kavre.Research Nepal Journal of Development Studies Vol.1(1) 2018 58-65

Exposure to mental health training and education in Canadian Armed Forces personnel
Authors: Zamorski Mark A. , Rusu Corneliu , Guest Kim , Fikretoglu Deniz
Published: October 2018

Introduction: The Canadian Armed Forces (CAF) mental health training and education (MHTE) program seeks primarily to enhance well-being and performance through enhancement of resilience and mental health literacy. Wider dissemination of its MHTE program is a strategic priority for the CAF, but the extent of MHTE exposure and risk factors for low exposure are unknown. The objectives of this paper are (1) to describe the extent of exposure to MHTE, and (2) to explore factors associated with less exposure. Methods: The 2013 CAF Mental Health Survey ( n = 8,165) assessed exposure to MHTE in six specific training contexts. Modified Poisson regression and ordered logistic regression explored risk factors for lack of any MHTE exposure and for fewer total training hours, respectively. Results: 69.7% of respondents had exposure to MHTE over the previous 5 years. The median number of training hours in those with at least some exposure was 11 (inter-quartile range 5 to 24). Similar risk factors were identified for no MHTE exposure and for fewer MHTE hours, though the models had relatively poor predictive value. Discussion: While most CAF personnel have had at least some exposure to MHTE, the extent of exposure varies substantially, and a significant fraction have had no exposure at all. While targeting groups with low exposure identified in this analysis makes sense, the substantial variability of exposure within those groups demonstrates the need for administrative data on training exposure at the individual level on an ongoing basis.

Jurnal ini membahas dan menjelaskan tentang optimasi antrian kendaraan, khususnya pada persimpangan jalan di kota-kota besar.Hal ini  dilatar belakangi oleh pengaturan waktu nyala Lampu Lalulintas pada persimpangan jalan tersebut yang nyalanya kurang effektif.  Dengan antrian semakin panjang, yang memungkinkan  akan menyebabkan kemacetan di jalan yang dekat dengan  persimpangan tersebut. Untuk menuju kepada kelancaran antrian  tersebut, maka akan diatur waktu nyalanya Lampu Lalulintas (terutama lampu warna Hijau) secara relatif Untuk mengatur lamanya waktu  nyala Lampu Lalulintas pada suatu jalur, tergantung dari kepadatannya antrian kendaraan tersebut. Begitu pula jika jalur lain atau yang berlawanan padat antrian kendaraannya, maka waktu yang lama untuk Lampu Hijau pindah ke jalur lain, atau bisa juga kedua-duanya, Disamping  Lampu  Hijau juga diatur nyala untuk Lampu yang warna kuning, dan merah. Dimana waktu nyala Lampu merah akan berlawanan dengan Lampu warna Hijau, tergantung padatnya antrian kendaraan. Pada saat ini di persimpangan jalan, Lampu Lalulintas belum semua memakai alat pengatur waktu untuk menentukan  berapa detik  nyala  warna Hijau, Merah, dan Kuning. Walaupun ada, masih bersipat konstan, tidak  memandang  apakah  antrian panjang atau pendek. Pada pembahasan ini yang  dibuat  hanya Game Simulasi  saja. yang berbasis Multi Agent cerdas, menggunakan logika Fuzzy,yang dilengkapi dengan Algoritma Greedy  Dalam  hal ini variabel Input, adalah kepadatan pada jalur I, jalur II,dan jalur III. Sedangkan  variabel output adalah Lamanya Lampu Hijau menyala untuk satu jalur. Variabel Input diasumsikan fungsi keanggotaan tidak padat, padat, dan sangat padat. Sedangkan variabel Output diasumsikan dengan fungsi keanggotaan Cepat, Sedang,  dan Lama.

Published: October 2018

It is known that password itself is not enough for formidable authentication method since it has a lot of vulnerabilities. Multi factor authentication (MFA) is introduced for the next generation for good authentication to address that issue. MFA combines two or more of three principles of good security, “something you know”, “something you have”, and “something you are”. Most MFA mechanisms work as one time passwords (OTP). However, they can still be vulnerable to phishing and MiTM attack. On top of that, OTP can be hard to use as it requires user to input another password given by the device (SMS, token, authenticator). Implemented in small USB U2F device, FIDO U2F delivers easier yet stronger security on authentication process which implements public key cryptography, challenge-response protocol, and phishing and MitM protection.

Outcomes for Hospitalized Older Adults with Down Syndrome in the United States
Authors: Mendiratta Priya , Wei Jeanne Y. , Dayama Neeraj , Li Xiaocong
Published: October 2018

Background:

Patients with Down syndrome (DS) often survive into adulthood. Relatively little information is currently available regarding hospitalization outcomes among mature, older adults with DS.

Objective:

To identify risk factors associated with hospital mortality rates and increased costs for hospitalized older adults with DS.

Methods:

Data on hospitalized older adults with DS (≥65 years) were identified from the Nationwide Inpatient Sample database (6) from 2002 through 2012. Multivariate analyses were performed to evaluate risk factors associated with hospital mortality and hospitalization cost in these patients.

Results:

A total of 2,134 older adults with DS were identified. A temporal increase over the 11-year period was observed in the number of older adults with DS who were hospitalized (trend p < 0.0001). However, the hospital mortality rate and post-hospital discharge to skilled nursing facilities have decreased during the same time period. Risk factors associated with increased hospital mortality included advanced age (70–79 years), female gender, admissions in the western United States, and presence of comorbid conditions (ischemic heart disease, Alzheimer’s disease, and cerebrovascular accident). The mean cost was $18,241 (SD $56,105) over the 11-year period. However, no significant temporal changes in costs were noted (trend p = 0.14).

Conclusions:

The number of hospitalized elderly Americans with DS has increased over the 11-year period. However, hospital mortality and discharge to skilled nursing facilities have decreased during the same time period. Several demographic and co-morbid factors are associated with increased mortality. No significant differences in temporal trends in costs were noted.

Since the University of Zurich required all departments to use the same content management system, a makeoverof our Main Library’s website was planned for 2017. Following Steve Krug’s book Don’t make me think, revisited,we reduced the contents and tried to build an easy to understand and straightforward navigation for the users. Toverify our concept, we arranged “do-it-yourself” usability tests. Three test sessions with three persons each weresufficient to find out what had to be improved on the website, and were more helpful than hours of discussionamong the team. Usability testing helped us to understand our customers' search behaviour and expectations fornavigation. It was also entertaining and a novel way of interacting with our customers.

SUPERVISI KLINIS
Authors: Nurcholiq Mochamad
Published: October 2018

Pendekatan klinis atau supervisi klinis berasumsi bahwa proses belajar guru untuk berkembang selalu terkait dengan proses belajar guru sendiri yang bersifat invidual. Pendekatan klinis merupakan proses tatap muka antara supervisor dengan guru. Pertemuan ini membicarakan masalah mengajar dan yang berhubungan dengannya. Oleh karena itu dalam supervisi klinis supervisor dan guru berperan sebagai teman sejawat dalam memecahkan masalah-masalah pembelajaran. Untuk tipe guru yang berbeda-beda, maka pengawas harus membedakan juga jenis strategi supervisi klinis yang akan digunakan. Tipe guru yang profesional cocok digunakan strategi non-direktif, tipe guru tukang kritik dan guru yang sibuk bisa digunakan strategi kolaboratif. Sedangkan untuk guru yang tidak bermutu, pengawas diharapkan lebih bisa aktif dalam membimbing dan mengajari guru ini, sehingga strategi yang tepat adalah supervisi klinis langsung.

Published: October 2018

The geostationary satellite of SBAS transmits not only corrections but also provides the code C/A on the L1 frequency. On which SBAS geostationary satellites like GPS satellites provide pseudo-ranges measurement C1. The features of this measurement is that it is always permanent because geostationary satellites do not move. This will be an additional source of pseudo-range measurement for the GPS system. With the current constellation of all SBAS systems, the number of operational geostationary satellites in orbit around the equator has risen to 12 (the number will increase in the future) and be distributed to give global coverage. The objective of this study is to present several surveys to evaluate accuracy improvement capability in point positioning when processing mixed measurements from the geostationary satellites in the SBAS and GPS. The results show that PDOP can be improved from 1.2 to 1.7 times when mixed processing.

Published: October 2018

Monitoring of rice growth is a requirement for high quality rice production. In addtion to plant height, number stem and rice leaf color, vegetation coverage (VC) which represents for percentage of ground covered by rice plant is also considered as an important index to validate rice growth. Thus, the study is to estimate rice vegetation coverage from difference vegetation index (DVI) calculated from reflectance of near-infrared and red band of Landsat 7 and 8 images. The field observations of the reflectance and the VC were carried out in two paddy rice varieties in 2013. Paddy field reflectance was observed by spectrometer Ocean Optics SD2000. The photos of paddies were taken from the height of 1 m by a digital camera in order to calculate the VC. The reflectances of paddy field corresponding to red and near-infrared bands of Landsat 7 and 8 were calculated from the field observation data. Satellite reflectance was also converted from pixel value of Landsat images. According to the data analysis, VC rapidly increased in two fields and got saturation status (VC>90%) at 65 days after transplanting (DAT) in the early July. DVI was approximately 25% when VC saturated. Additionally, DVI had strong correlation with VC with high determination coefficient (r2 =0.9) when VC was less than 90%. Thus, VC were computed from DVI, calculated from reflectances of Landsat images, using a regression model of VC and DVI. From the result of comparison between the estimated and computed VC, the possibility of estimating VC from DVI calculated from Landsat reflectance is confirmed.

Published: October 2018

Using descriptive statistics, the authors analyze influence of catastrophes and epidemics to 287 farming households in the Central Highlands. The results indicate storms, pests, epidemics and avian flu exert the most severe impact. The average loss caused by these catastrophes and epidemics is pretty large, decreasing over the time yet more complicated and occurring more frequently. In addition, more than 70% farming households adopt quite passive coping strategies which result in low recovery rate. This paper, therefore, proposes crop insurance mechanisms, improved irrigation system and selecting more suitable seedlings to the region

Controlling the retention and separation of water–soluble vitamins on zwitterion column by hydrophilic interaction echanism
Authors: Nguyen Vinh Ngoc , Nguyen Luyen Thi Thuy , Nguyen Giang Tien , Nguyen Du Huy , Nguyen Mai Anh
Published: October 2018

Chromatographic conditions including pH, type and concentration of buffer for separation of five B vitamins on ZIC-HILIC column were investigated. Ammonium formate, ammonium acetate and ethylendiamonium chloride were used as buffer salts in the study. The results revealed that pH and buffer identity had significant effects on charged analytes. Indeed, ethylenediamonium competed very well with positively-charged analytes when the excessive retention was the problem while pH could control the charge state of the vitamins. The quanlity of acetonitrile was also employed to control the elution power in general. The mobile phase containing 10 % 40 mM ethylendiamonium chloride at pH 2.5 and 90 % ACN by volume was found to be the most suitable to separate the vitamins. The calibration curves had the R2 > 0.997, % RSD of retention time and peak areas in most of the cases were lower than 1% and 3.2 %, respectively. The developed method was applied to determine the B vitamins in Trivita BF, a commercial pharmaceutical product.

Anti-chloramphenicol rabbit antibody was covalently bound to Sepharose CL 4B-CNBr gel at 5, 10 and 15 mg antibody per mL gel and was fed into columns to prepare three respective immunoaffinity chromatography columns for chloramphenicol (CAP) binding. Examination of CAP-binding efficiency of these columns being fed with 0.5, 1 and 10 ng CAP showed that the column with 10 mg antibody per ml gel (IAC-CAP-10 column) could bind more than 90 % of the CAP amount having been fed into the column at all three examined CAP amounts. This IAC-CAP-10 column showed a coefficient of variants (CV) between columns upon CAP binding of 5.18 % for 1 ng fed CAP and 1.98 % for 10 ng, respectively, a loading capacity of 153,37 ± 10,32 ng CAP, stable CAP-binding performance during at least 2 years of preservation at 4 °C. The coupling of this IAC-CAP-10 column with liquid chromatography - tandem mass spectrometry LC MS/MS could make CAP analysis become possible with a limit of detection LOD of 0.033 ng and a limit of quantification LOQ of 0.101 ng. The column could also bind to the other two phenicol antibiotics: florfenicol and thiamphenicol with a binding efficiency of 90.73 % for florfenicol and 84.29 % for thiamphenicol.

This study focuses on the development and characterization of polyurethane/bamboo fiber composites foams which have the specific properties to participate both in the thermal insulation and regulation of the humidity inside the building. The polyurethane foam reinforced by bamboo fibers (5–20 wt%) were produced to investigate the mechanical test, the morphological characterization and thermal properties. The result from mechanical test showed that the compressive strength was increased at 5 wt % of bamboo fiber. Likewise, the effects of the fibre diameter and nature of bamboo fibers on some properties (compressive test, thermal analyses, surface morphology) of bamboo fibre reinforced rigid polyurethane foam were studied. The bamboo Gai and Luong fibres result in composites with better mechanical strength than the other fiber composites.

Published: October 2018

Synergetic catalytic effect of molybdenium (Mo) and chromnium (Cr) ions on HZSM-5 support have been carried out. The catalyst of MoCr/HZSM-5 have been tested for iszomerization of n-hexane based on non-hydrogen reaction. The results showed that the catalytic synthesis by impregnating Mo and Cr on HZSM-5 support with the suitable amount ( Mo:10 %; Cr:3 %) did not change the basis structure of HZSM-5. The catalytic effect of Mo, Cr have been showed by catalytic testing results, for that the isoparaffin selectivity of MoCr/HZSM-5 is 46.5 % higher than in the case of Mo/HZSM-5 (43.56 %). The synergystic catalytic activity was clearly expressed by the dehydrogenation and hydrogenation role of Cr enhancing the stability of isomerization effect of Mo on MoCr/HZSM-5 catalyst for n-hexane’s isomerization reaction. Research results could be considered as the scienctific basis results for catalytic research applied to gasoline high quality production from the condensate feed by non-hydrogen technology in Vietnam.

Gold–Silver alloy nanoparticles were synthesized by microwave assisted redution and polyol reactions, where trisodium citrate (TSC) and poly vinyl pyrollidone (PVP, Mn=1,000,000) played as protective agents, process includes two steps: (i) first, gold nanoparticles were synthesized, (ii) then silver nanoparticles were developed on gold nanoparticles surfaces to form alloy nanoscale. The results of the analysis from UV-Vis, XRD, TEM spectrums showed that gold – silver alloy nanoparticles mostly had core–shell structure and gold was proposed as the core. The particle size of alloy nanoparticles was 30–35 nm, and developed if the amount of silver has increased. UV-Vis spectrum showed this solution has a shoulder peak beside maximum absorbent peak. Trisodium citrate kept an important role to form gold–silver alloy nanoparticles in ethylene glycol.

Species composition and characteristic of zooplankton communities in treated leachate of Dong Thanh landfills and in Rach Tra river (receiving the wastewater of Dong Thanh landfills) were surveyed monthly from 11/2012 to 04/2013. The results from those two areas were compared to find out the difference of the zooplankton communities. 122 species of 36 genus, 10 classes, 3 phylums and 6 types of larva were identified, of which Rotatoria acounted for 52 %. The result of Cluster analysis showed that there was a distinct difference between the zooplankton community intreated inside the landfills and Rach Tra river. The zooplankton community inside the landfills characterized by low quantity of species but high individual density. The main species composition was Rotatoria and Protozoa with good adaptation of organic and microbiological pollution of water. On the other hand, the zooplankton community in Rach Tra river characterized by communities in natural aquatic habitat with the relative balance of zooplankton groups, diversity index and dominance index were average levels.

An Tho Castle (An Dan Ward, Tuy An District, Phu Yen Province) was built in the reign of Minh Menh. It was the capital of Phu Yen Province for a long time. In August 1945 Revolution, in the two wars against France and the United States, the castle became a fierce duel between the resistance forces and ethnic enemies. This is also the birthplace of Tran Phu – the General Secretary of the Communist Party of Vietnam. In 2008, the ancient castle conducted some archaeological excavations by the Culture, Sports and Tourism Department of Phu Yen Province and the University of Social Sciences and Humanities, VNU-HCM to determine the scientific value of the relics. Through excavation, the entire old ground as well as some buildings (i.e. the area of road building, front yard, old wells, gates of various locations such as front, back, left, right, etc.) already existed. Many types of relics of numerous different materials such as stone, bronze, iron, terracotta, ceramic, porcelain, coins under the reign of Kings Minh Mang, Thieu Tri, Tu Duc and some stone bullets, cast iron were used for the defense of the city. Nowadays, with the advantages of geographical location, terrain, scenery, special sizes of architecture and relics of the past An Tho Castle, through archaeological excavations and historical culture, the surrounding landscape, we absolutely can confidently invest in the development of exciting new tours to contribute to the economic development of the province and the region.
