Still Spraying?: Virtual Chromoendoscopy

Now we are in the era of video endoscopy passed through optic fiberoscopy in 1980s. The development of endoscopic equipment leads to significant change and growth in the field of gastroenterology, allowing correct and detailed examination of microscopic lesions. By correlating endoscopically detected lesions with pathologic finding and assessing the disease progress, the academic area of gastroenterology, especially for the gastrointestinal tract disease has been expanded and consolidated. The development of optical imaging technology is in progress. In the early 2000s, new technology called ‘image-enhanced endoscopy’ was incorporated to GI endoscopy equipment leading to new paradigm in the field of GI endoscopy. Among image-enhanced endoscopies currently known, two representative techniques are narrow-band imaging (NBI) and autofluorescence imaging (AFI). These techniques are developed for finding and observing subtle mucosal abnormality, and especially in colon, these are useful for detecting or differentiating epithelial tumors (polyps). Initially, good results had been reported mainly from the countries which developed these techniques but recently, there are many studies from worldwide reporting contradictory results, so the efficacy and benefit are controversial still. Image-enhanced endoscopy, mainly NBI has been used increasingly in Korea and notably in primary medical facilities. But the indications and benefits of these techniques are not established yet. In this report, we will discuss the use of image-enhanced endoscopy in the diagnosis and treatment of colonic epithelial tumors focusing on the unsettled area of these techniques.
Preliminary estimates of consumption rates of Rapana venosa (Gastropoda, Muricidae); a new threat to mollusk biodiversity in the Río de la Plata

The veined whelk Rapana venosa (Valenciennes, 1846) is an active, Asian, invasive mollusk predator that has been present along the coastal zone of Maldonado, Uruguay since 2004. The feeding rate of R. venosa on native mussels was estimated in a laboratory experiment. A flume with a constant water flow was used, in which the mean (± SD) temperature was 25.4 ± 1.8 °C, the mean (± SD) salinity was 18.5 ± 1.6, and a 15:9 light-dark schedule was followed. Each experimental trial lasted 9 days and a constant prey supply was maintained. Three size classes of predators and three size classes of prey (Brachidontes rodriguezii and Mytella charruana), were used. For all sizes of predator combined, the average (± SD) absolute consumption rate was 0.88 ± 0.3 g day -1 , and the relative consumption rate was 0.057 ± 0.034 g g -1 day -1 . No significant differences were found between the number of prey and total grams consumed among the three size categories of snails. However, for the relative consumption rate, small snails consumed significantly greater (0.10 g g -1 day -1 ) amounts than intermediate and large snails (0.04 and 0.02 g g -1 day -1 respectively). All sizes of snails consumed significantly more intermediate- than small-sized mussels. This study provides important knowledge for future research to assess the impact of this invasive species on native bivalve resources.
The Relationship between Macroeconomic Variables and Stock Market Index in Nigeria

Abstract This study is an attempt to determine the relationship between macroeconomic variables and the Nigerian capital market index. It considers the yearly data of several macroeconomic variables of interest rates, inflation rates, exchange rates, fiscal deficit, GDP and money supply from 1975 to 2005; and it tries to reveal the relative influence of these variables on the ‘All Share Index’ of the Nigerian capital market. In pursuance of this, the Vector Error Correction Model (VECM) was used to study the short-run dynamics as well as long-run relationship between the stock market index and the six selected macroeconomic variables from the Nigerian economy. The major finding is that macroeconomic variables influence stock market index in Nigeria. It is recommended that the adoption of appropriate economic policies will be beneficial to the stock market index [a proxy for stock prices] and this in turn will result in needed growth in the capital market.
Learning to program - difficulties and solutions

Programming is a fundamental part of computer science curriculum, but it is often proble matic. The high drop out and failure rates in introductory programming courses are a universal problem that motivated many researchers to propose methodologies and tools to help students. Although some of these tools have been reported to have a positive effect in stu dents learning, the problem still remains mostly unsolved . We think that there are several reasons that cause thi s learning problem. Maybe the most important is the lack of problem solving abilities that many students sho w. They don't know how to program, because they don't know how to create algorithms, mainly due to their lack of general problem solving abilities. This and othe r causes to student difficulties are discussed in thi s paper. Some possible solutions are proposed, so that probl ems can be reduced.
An Appraisal of the Impact of Audit Qualifications on Firms’ Stock Exchange Price Fluctuations

Normal 0 21 false false false TR X-NONE X-NONE MicrosoftInternetExplorer4 Audit reports constitute the basic mean of communication between the auditor and the users of financial statements. Consequently, statements have to be comprehensible and inclusive, in order to be rightly appreciated and used by investors in their decision-making process. Nevertheless, the importance that the investors attribute to reports and their contents is questionable and needs to be further investigated. The results of an abundance of published on the matter lead to controversial conclusions. This aim of this paper is to examine audit reports that have been issued and published for companies with shares on the Athens Stock Exchange ( ASE ) during the 2005-2007 periods . By using the market model and calculating bonuses, the impact of the auditing report on a company’s stock price is examined. Research results indicate that audit reports have limited informational content for investors and do not form part of their decision making process . This may be due to the lack of understanding for the contents , importance and value of such reports .

The Interpretation of Unit Value Indices - Unit Value Indices as Proxies for Price Indices

The unit value index (UVI) as compiled in Germany for exports and imports is compared with two other indices, viz. an index of Drobisch which unfortunately is likewise known as "unit value index" and the "normal" Laspeyres price index (PI) of exports and imports. The UVI may be viewed as a Paasche index compiled in two stages where unit values instead of prices are used in the low level aggregation stage. Unit values are average prices referring to an ag-gregate of (more or less homogeneous) commodities. The focus of the paper is on the decom-position of the discrepancy between UVIs and PIs (the "unit value bias") into a (well known) Laspeyres (or substitution) effect or "L-effect" and a structural component or "S-effect" due to substituting unit values for prices. It is shown that amount and sign of S depends on the corre-lation between the change of quantities of those goods that are included in the aggregate and their respective base period prices. By contrast to L the correlation between quantity and price movement is not relevant for S.

Plasma Aminothiol Profile and Some of Its Determinants in Apparently Healthy Azorean Subjects

Objectives. To evaluate the plasma aminothiol profile (PAP) and serum gamma-glutamyltransferase (GGT) activity, as well as plasma folate, vitamin B12, and vitamin B6 concentrations, in 326 apparently healthy subjects from the Azores archipelago (Portugal). Also eventual relationships of PAP with conventional risk factors for atherosclerosis were investigated, aiming at the finding of early blood markers of the disease. Design and Methods. This was an observational cross-sectional study, where participants were split into two groups: one with a normal and another with an altered PAP (at least one aminothiol out of its reference concentration range). Results. About 76% of subjects had an altered PAP, mainly due to low glutathione levels (<1.5 μmol/L), mostly associated with normal GGT activity. Prevalence of hyperhomocysteinemia was 10%, where only 33% had some B-vitamin deficiency. The risk for atherosclerosis was more evidenced in subjects exhibiting both deficient GSH concentration and increased serum GGT activity. Conclusions. An altered PAP, namely, when caused by low GSH levels in the absence of alterations in the Hcy, or Cys, or Cys-Gly concentrations and in serum GGT activity, might reveal a subclinical stage of atherogenesis and should be explored as a potential early marker of atherosclerosis.
LBMS: LOCATION BASED MOBILITY SCHEME IN WIRELESS SENSOR NETWORKS

A wireless sensor network can work efficiently only if can provide good mobility support. However the existing mobility protocols do not provide the optimal solution due to long handover latency and high packet loss. The term handover or handoff refers to the process of transferring an ongoing call or data session from one channel connected to the core network to another channel this leads to delay. In order to overcome these disadvantages we use location-based mobility support scheme. Mobility support algorithm is used which is based on cluster domain. In this scheme the handover in data link layer (DLL) and network layer are done simultaneously and mobile nodes do not participate in handover process. Hence packet loss due to change in address and node mobility is avoided. Moreover a cluster head's IPV6 address includes location information so there is automatic establishment of routing path to the destination cluster without routing discovery. The main advantage of using location based mobility support is that packet loss and handover cost is reduced. The task of routing data from a source to the sink is a critical issue in wireless sensor networks. To overcome these critical issues we use fuzzy logic to perform role assignment during route establishment and maintenance is proposed. An incremental approach is presented and compared with similar existing routing protocols. Efficient routing approaches provide network load balance to extend network lifetime, efficiency improvements, and data loss avoidance.
Some aspects of teaching the technology of designing and planning information systems in health care

In this article, we use the well-known ideas of technology in designing of new information systems in health care. We explain the principle that “making a health care application” “is more than writing a program”, “it requires a strong co-operation and continuous contact” between the system analysts and users. The concept of the information system must contain the work of the whole system, which means that the planning and designing process should focus on the services, which really support the customer’s functions. It has to be compatible with the earlier information systems based on several decade’s experience. In this paper we use the most important elements of system theory. First of all we explain why it is important to take into account the behaviour of those, who operate the information system, and also their habits and way of thinking when planning then information system. We emphasise that it is importance to overview the whole information system and its functionality because it is a major aspect of the system planning. This paper can be used in university courses especially in teaching SDM, SSADM, Martin, etc. technologies for information system analysts, program designers and programmers.
On algebras of relations

Throughout, by relation we mean a binary relation. Let Rel(X) be the set of all binary relations on the set X. An algebra of relations is a pair (Φ,Ω) where Ω is a set of operations on relations and Φ ⊂ Rel(X) is a set of relations closed under the operations of Ω. Each algebra of relations can be considered as ordered by the set-theoretic inclusion ⊂. Denote by M{Ω} the class of all algebras isomorphic to ones whose elements are relations and whose operations are members of Ω. The class M{Ω,⊂} is determined in the same way. We will consider the following operations on relations: relation product ◦, relation inverse −1, intersection ∩, diagonal relation ∆, and the unary operation ∗ determined as follows: %∗ = % ∩∆. The class M{◦,−1 ,∩, ∆} was introduced and characterized in [6]. It is not finitely axiomatizable [5]. The classes M{◦,−1 , ∆} and M{◦,−1 , ∆,⊂} were characterized in [1, 8]. The class M{◦,−1 , ∆} is not finitely axiomatizable [2]. In this paper we find a system of axioms for the class M{◦,−1 ,∗ , ∆,⊂} and use it to obtain some results about the class M{◦,−1 ,∩, ∆}. Theorem 1. An algebra (A, ·,−1 ,∗ , 1,≤) belongs to M{◦,−1 ,∗ , ∆,⊂} iff it satisfies the following conditions: (1) (A, ·,−1 , 1) is an involuted monoid , i.e. (xy)z = x(yz), 1x = x1 = x, (x−1)−1 = x, (xy)−1 = y−1x−1. (2) ≤ is an order relation and all operations are monotonic, i.e. x ≤ y implies xz ≤ yz, zx ≤ zy, x−1 ≤ y−1, x∗ ≤ y∗. (3) The following identities are satisfied :
Proposed Algorithm for Surveillance Applications

Technological systems are vulnerable to faults. In many fault situations, the system operation has to be stopped to avoid damage to machinery and humans. As a consequence, the detection and the handling of faults play an increasing role in modern technology, where many highly automated components interact in a complex way such that a fault in a single component may cause the malfunction of the whole system. This work introduces the main ideas of fault diagnosis and fault-tolerant control under the optics of various research work done in this area. It presents the Arduino technology in both hardware and software sides. The purpose of this paper is to propose a diagnostic algorithm based on this technology. A case study is proposed for this setting. Moreover, we explained and discussed the result of our algorithm.

Determinants of inflation in Tanzania

Summary ISSN 0804-3639Tanzania’s inflation rate which averaged about 30% in theearly 1990’s dropped to about 13% at the end of 1998. Usingan error correction model (ECM), this paper estimates aninflation equation for Tanzania based on quarterly data, forthe period 1992:1 to 1998:4. The results from the econometricregression analysis shows that inflation in Tanzania, eitherin the short run or the long run, is influenced more by monetaryfactors and to a lesser extent by volatility in output ordepreciation of the exchange rate. It is recommended that tocontrol inflation in Tanzania, the government should pursuetight monetary and fiscal policies. In the long run, thegovernment should also pursue policies to increase foodproduction to ease some of the supply constraints. Samuel A.

Problems in Artificial and Natural Revegetation of the Arid Shadscale Vegetation Zone of Utah and Nevada.

Attempts to revegetate the Great Basin sagebrush zone have been relatively successful, especially where annual precipitation exceeds 10 inches (Stoddart 1946; Plummer et al. 1955). Artificial seeding attempts in the drier shadscale zone generally have failed. Revegetation is needed to increase forage, to reduce erosion, and to control poisonous or noxious plants. This paper results from seeding trials and problems in revegetation of the arid shadscale zone. Native vegetation. -The shadscale vegetation zone, also called salt desert shrub, covers over 40 million acres mainly in the southern and southwestern parts of the Intermountain region: Clements (1920) ; Graham (1937) ; Fautin (1946) ; Price et al. (1948) ; and Billings (1949). Isolated islands of the zone extend into eastern Oregon, southern Idaho, and southwestern Wyoming. Included in the shadscale zone are
Communities of practice in construction case study organisations : questions and insights

Purpose – At the heart of knowledge management (KM) are the people – an organisation's important knowledge asset. Although this is widely acknowledged, businesses seldom understand this axiom in terms of the communities through which individuals develop and share the capacity to create and use knowledge. It is the collective learning that takes place within the social systems, i.e. communities of practice (CoP) that are of particular significance to an organisation from a KM perspective. This paper aims to review, critique, and raise some pertinent questions on the role of CoPs; and with the help of case studies shed light on the “goings‐on” in construction practices.Design/methodology/approach – After critically reviewing the literature on CoPs and querying some underlying assertions, this research investigates how these issues are addressed in practice. A case study approach is adopted. Three organisations operating in the construction sector are interviewed for the purpose of this paper.Findings – Case.
ENHANCING FINANCIAL SYSTEM STABILITY IN INDONESIAN DUAL FINANCIAL SYSTEM

In a country adopting dual financial system (conventional and Islamic), monetary authority has the responsibility to maintain financial stability and synergy of both systems by stabilizing price level and promoting economic growth. Three main pillars, which differentiate between the Islamic and conventional financial system, are international monetary system, banking system and financial operation system. Conventional financial system adopts fiat money/ multiple fiat currency, fractional reserve banking and interest systems. Meanwhile, Islamic financial system adopts gold money, Islamic narrow banking and profit-and-loss sharing systems. The main objective of this study is to compare the three main pillars of conventional and Islamic financial system in curbing inflation and promoting economic growth. This study applies Vector Error Correction Model (VECM) using Indonesian data. The results show that interest (INT), fiat money (M0) and multiple fiat currency (EXCH) systems in conventional financial system are the main determinants that induce inflation as well as hinder economic growth. INT induces inflation with 38.44% share and hinders economic growth with 71.72% share. The results also show that profit-and-loss sharing (PLS) and Gold (or Gold-backed) Money and/or Single Gold Standard (GOLD) systems in Islamic financial system are the main determinants that curb inflation, as well as promote economic growth for GOLD. GOLD curbs inflation with 0.66% share and promote economic growth with 4.07%. Therefore, the share of Islamic financial system with PLS and GOLD should be increased to its optimum level.
Stochastic velocity motions and processes with random time

The aim of this paper is to analyze a class of random motions which models the motion of a particle on the real line with random velocity and subject to the action of the friction. The speed randomly changes when a Poissonian event occurs. We study the characteristic and the moment generating function of the position reached by the particle at time t > 0. We are able to derive the explicit probability distributions in few cases for which discuss the connections with the random flights. The moments are also widely analyzed. For the random motions having an explicit density law, further interesting probabilistic interpretations emerge if we deal with them varying up a random time. Essentially, we consider two different types of random times, namely Bessel and Gamma times, which contain, as particular cases, some important probability distributions (e.g. Gaussian, Exponential). In particular, for the random processes built by means of these compositions, we derive the probability distributions fixed the number of Poisson events. Some remarks on the possible extensions to the random motions in higher spaces are proposed. We focus our attention on the persistent planar random motion.
