Hualong Yang, Khin Lin, Otieno Robert Kennedy, Banomyong Ruth
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.43045
Abstract: Sea-port operational efficiency is critical factor for handling of goods in the international supply chains, and is viewed to impact transportation and logistics which play an important role in trade exchange with other countries. It is important to evaluate operational efficiency of sea-ports to reflect their status and reveal their position in this competitive environment. Moreover, knowing impacts of efficiency of sea-ports on the supply chain is vital for business survival. This study uses stochastic frontier and inefficiency models to analyze sea-port operational efficiency and Delphi technique to seek expert respondents’ opinion on its characteristics. The research also uses structural equation modeling to build a model of sea-port operational efficiency as a further step to examine the significance of the characteristics. The results of this study emphasize the need to improve sea-port operational efficiency, and indicate which characteristics should be given more attention.
Geographic and Ethnic Distribution of P knowlesi infection in Sabah, Malaysia
Daw Khin Saw Naing,Fread Anderios,Zaw Lin
International Journal of Collaborative Research on Internal Medicine & Public Health , 2011,
Abstract: Background: Plasmodium knowlesi, an originally zoonotic malaria parasite is now increasingly recognized as a potentially virulent type of human malaria, particularly in South East Asia. The initial diagnosis based on light microscopy would not differentiate P knowlesi from P malaria and the nested PCR (Polymerase Chain Reaction) assay is the only reliable diagnostic method to correctly differentiate the two species. Sabah State Public Health Laboratory has launched its PCR service in 2007 for all government hospitals of Sabah to get accurate verification of malaria species. Sabah state is famous for its significant tourist attraction sites, of which Mount Kinabalu and Tip of Borneo are the most unique and mostly visited. A large variety of ethnic groups reside in Sabah with Kadazan-Dusun forming the largest indigenous group followed by Bajau and Murut.Aim & Objectives: To determine the geographic and ethnic distribution of zoonotic malaria among Sabah population so as to recommend effective preventive and control measures at popular tourist sites of Sabah. Methods/Study Design: A record review of all nested PCR assays done during 2009 at Sabah State Public Health Laboratory was made. SPSS version 16 and Microsoft excel 2007 softwares were used in analysis.Results/Findings: 445 cases were referred in 2009 for PCR assay from various hospitals of Sabah. Age range was 1 to 89 years (33±18 years) and about 12 % were symptomatic cases while the rest were confirmed malaria by microscopy. 343 cases (253 males and 90 females) were positive for Plasmodium knowlesi single infection or mixed with other species. Mixed infection with vivax was common (65 males and 18 females). Only two cases each for mixed infection with falciparum and malarie were detected. P knowlesi infection was confirmed in all age groups (under five as well as over 80).Among the positive cases, about 32% were Rungus, 28% Dunsun and 15% Murut. 41.7% were from Kudat which is close to the Tip of Borneo and 16.3% came from Ranau area in which Mount Kinabalu is situated. Keningau and Tenom areas contributed 15% each.Study Limitations: The PCR assay was done only on hospital referred cases that the study results would not reflect the actual community prevalence.Conclusion: Major tourist attraction sites showed high number of P Knowlesi infection calling for establishment of effective preventive measures against this monkey related malaria in Sabah.
Low-Density Co-Inoculation of Myanmar Bradyrhizobium yuanmingense MAS34 and Streptomyces griseoflavus P4 to Enhance Symbiosis and Seed Yield in Soybean Varieties  [PDF]
Khin Myat Soe, Takeo Yamakawa
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.49231
Abstract:

This study examined whether low-density co-inoculation of Myanmar Bradyrhizobium yuanmingense strain MAS34 and Streptomyces griseoflavus P4 would enhance nodulation, N2 fixation, and seed yield in two soybean varieties. A field experiment was conducted during the July to November 2012 growing season at Kyushu University Farm, Japan, using a split-plot design with three replications and the following four treatments: T1, an uninoculated treatment with peat moss (uninoculated); T2, a single inoculation with S. griseoflavus P4 (P4); T3, a single inoculation of B. yuanmingense MAS34 (MAS34); and T4, a dual inoculation of P4 with MAS34 (P4 + MAS34). Two varieties of soybean, Yezin-3 (Rj4) and Yezin-6 (non-Rj), were used. The N2 fixation activity of soybean was evaluated by the relative ureide method using xylem solute from root bled sap at the early pod-fill stage (R3.5). Dry matter production, N2 fixation, and seed yield were significantly (P < 0.01) different between the inoculated treatments. The effect of variety was also sig

Measuring Qualities of XML Schema Documents  [PDF]
Tin Zar Thaw, Mie Mie Khin
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.69056
Abstract:

The Extensible Markup Language (XML) is becoming a de-facto standard for exchanging information among the web applications. Efficient implementation of web application needs to be efficient implementation of XML and XML schema document. The quality of XML document has great impact on the design quality of its schema document. Therefore, the design of XML schema document plays an important role in web engineering process and needs to have many schema qualities: functionality, extensibility, reusability, understandability, maintainability and so on. Three schema metrics: Reusable Quality metric (RQ), Extensible Quality metric (EQ) and Understandable Quality metric (UQ) are proposed to measure the Reusable, Extensible and Understandable of XML schema documents in web engineering process respectively. The base attributes are selected according to XML Quality Assurance Design Guidelines. These metrics are formulated based on Binary Entropy Function and Rank Order Centroid method. To check the validity of the proposed metrics empirically and analytically, the self-organizing feature map (SOM) and Weyuker’s 9 properties are used.

Histopathological Diagnostic Discrepancies in Soft Tissue Tumours Referred to a Specialist Centre
Khin Thway,Cyril Fisher
Sarcoma , 2009, DOI: 10.1155/2009/741975
Abstract: Aims. A study was performed to determine areas of diagnostic discrepancy in the reporting of cases of soft tissue tumours referred to a specialist sarcoma unit. This was to pinpoint common discrepancies and to determine their causes. Methods and Results. We compared the sarcoma unit's histopathology reports with referring reports on 349 specimens from 277 patients with suspected or proven soft tissue tumours in a one-year period. Conclusions. Diagnostic agreement was found in 256 of 349 cases (73.4%), with minor diagnostic discrepancy in 55 cases (15.7%) and major discrepancy in 38 cases (10.9%). Benign/malignant discordances accounted for only 5% of all discrepancies (5 cases). The most common discrepancies occurred in tumour classification, including diagnosis of gastrointestinal stromal tumour and leiomyosarcoma and the subtyping of spindle cell sarcomas, as well as in tumour grading that could conceivably lead to changes in clinical management. Major diagnostic discrepancies leading to management change occurred in a relatively select range of tumour groups, and almost all discrepancies occurred due to differences in tumour interpretation between general or nonsoft tissue pathologists, and pathologists at the specialist unit. The findings support guidelines by the National Institute for Health and Clinical Excellence that diagnostic review of soft tissue tumours should be performed by specialist soft tissue pathologists.
Economic and Accounting Interpretative Approach on Income Disparity: Evidence from China
Edward Wong Sek Khin
Asian Culture and History , 2010, DOI: 10.5539/ach.v2n1p59
Abstract: In this paper, we analyse the current China urban and rural income disparity. Our analysis demonstrates that the Economic and Policy reforms instituted by the Chinese government over the past decade or so have had two primary aims: Firstly, to maintain political stability at all costs and secondly to transform China into a modern industrial state. To ensure political stability, it has eschewed the current Russian model for a unique Chinese model where state owned enterprises co-exist with market driven businesses. This all began in 1978, after two disastrous near revolutions where the hard-line Marxist-Socialists had to concede that all was not well for the future of China, in a modern world. Beginning with the rural sector, where the pool of greatest poverty existed and improving in that sector firstly, allowed the market-oriented to greatly improve their incomes, thus changing the disparities between urban and rural economics. The period of 1985 to 2005 was a period of almost exponential growth, and the raising of millions out of poverty was only part of the positive results, but the greatest social negative was that inequality became worse, as is found in most Capitalist societies. There seems to be an initial jump in the incomes of rural China to jump out of poverty, but the effects have slowed, and it is now up to government agencies to aid the remaining impoverished to escape the traps of poverty through education and relocation incentives for industry, domestic and foreign. This does not mean throwing money at the problem, it means preventing destitution, as destitution adds to crime and other anti-social events and greatly increases instability, the anti-thesis of current Chinese policy. Perhaps the question ought to be a rethink of agricultural policies, to generate corporate farming, as opposed to collective farming, all in order to reduce rural poverty and make rural businesses into a proper and profitable sector of employment.
The Role of Reflective Practitioner Heuristic Inquiry in Institutional learning and Research
Edward Sek Khin Wong
International Journal of Education , 2010, DOI: 10.5296/ije.v2i1.236
Abstract: In this paper, the author reports on a critical and reflective practitioner heuristic inquiry that investigates a case study concern a post-modern approach in enhancing institutional teaching and research involving adult learning. In addition, the author investigates the research process itself and his own professional academic practices. Of particular interest is that this paper offers practitioners and teachers a new way of thinking about and pursuing concerns about a foray into many different disciplines, among these are sociology, education, business, strategic decision making, knowledge management, organisational theory, and current critical schools of thought, such as the work of Michel Foucault. The paper aims to bring out inner dialogues and open discourse responses in one-on-one interviews within a phenomenological, reflective practitioner methodology. The author seeks to explain why these roles are experiencing increased interest in the nature of critical institutional research. This approach assumes that any learning situation has the potential to yield new ideas for enhancing the researcher’s learning, provided we do the kinds of thinking that opens up new possibilities. That is, the researcher offers an account of this innovative thinking, suggesting a framework of questions, which practitioners can use, and then drawing upon their existing knowledge in order to generate new insights and possibilities for practice. One area of controversy between critical institutional research and the traditional research is the role of “reflective practice," which remains under-developed. In this paper is explored the importance of reflective practice employing the term "living thesis paradigm" as a means of developing expert research methods.
Cognitive Pattern Analysis Employing Neural Networks: Evidence from the Australian Capital Markets
Edward Sek Khin Wong
International Journal of Economics and Finance , 2009, DOI: 10.5539/ijef.v1n1p76
Abstract: An artificial neural network is an intelligent system using computers that allows users to improve performance through pattern recognition. Neural networks benchmark their predictions with actual results and constantly revise their predictions, improving forecasting capability. The purpose of this paper is to support the use of neural networks as a detection mechanism tool to discover market inefficiencies in financial markets. Using the Australian capital market as an example, this study investigates the question of the existence of market inefficiencies using artificial neural networks as the investigative tool. This study also focuses on whether additional publicly sourced information when used as input through a neural network, can provide investors with a trading advantage over traditional financial models. In finance, any forecasting advantage obtained through the use of publicly available information even if internal, external or both indicate some form of inefficiency in the financial markets. In this paper, we explore the efficiency of the four capital markets, the United States, Japan, Hong Kong and Australia, but focusing on the Australian capital market using the Australian Stock Exchange’s 200 (ASX 200) index. Our research demonstrates how the inclusion of external information to our neural network model can provide a significant trading advantage. Although our preliminary analysis suggests the Australian market is as efficient as the US market, other results suggest the Australian market may be less efficient, when we take into account of external information from other financial markets. Our results show that accounting for external market signals can significantly improve forecasts on the ASX200 index but show little benefit on forecasts for the Dow Jones Industrial Average (DJIA) index. Using external market signals, our neural network model’s prediction accuracy of the ASX200 index increases by an additional 10 percent from 50 to 60 percent accuracy. This suggests the inclusion of publicly available external signals can significantly improve neural network forecasts. By exploiting this additional information, this method can improve returns for investors who incorporate such signals in their neural network models.
Employing Artificial Intelligence To Minimise Internet Fraud
Edward Wong Sek Khin
International Journal of Cyber Society and Education , 2009,
Abstract: Internet fraud is increasing on a daily basis with new methods for extracting funds from government, corporations, businesses in general, and persons appearing almost hourly. The increases in on-line purchasing and the constant vigilance of both seller and buyer have meant that the criminal seems to be one-step ahead at all times. To pre-empt or to stop fraud before it can happen occurs in the non-computer based daily transactions of today because of the natural intelligence of the players, both seller and buyer. Currently, even with advances in computing techniques, intelligence is not the current strength of any computing system of today, yet techniques are available which may reduce the occurrences of fraud, and are usually referred to as artificial intelligence systems.This paper provides an overview of the use of current artificial intelligence (AI) techniques as a means of combating fraud.Initially the paper describes how artificial intelligence techniques are employed in systems for detecting credit card fraud (online and offline fraud) and insider trading.Following this, an attempt is made to propose the using of MonITARS (Monitoring Insider Trading and Regulatory Surveillance) Systems framework which use a combination of genetic algorithms, neural nets and statistical analysis in detecting insider dealing. Finally, the paper discusses future research agenda to the role of using MonITARS system.
Ambiguity in Contemporary Market Definition Statute in the Australian Jurisdiction: A Critical Examination from Two Australian Case Studies
Edward Sek Khin Wong
Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v2n1p16
Abstract: This paper investigates and critical analyses the market definition issues in News Ltd v Australian rugby Football League Ltd (19960 ATPR 41-466 and in Regent Pty Ltd v Subaru (Aust) Pty Ltd (1998) ATPR 41-647. Here the author examines the application of the provisions of the Trade Practices Act 1974 (Commonwealth) particularly sections 4, 45, 46 and 50 in relation to ‘market definition in Australia’. By attempting to critically analyse the issues of market definition within the per se rule and the rule of reason in an Australian legal sense, the author seeks an explanation to outline the key elements one needs to establish under the ‘substantial lessening of competition test’, ‘the notion of substitution’, ‘otherwise competitive with,’ and ‘the time factor’ in relation to market definition.
