Many aquatic ecosystems suffer from anthropogenic disturbances, including the introduction of damaging levels of toxic substances. The effects of disturbances include complex relations with various components involved in the systems, and can include physical, chemical, and hydrological disruption depending of the contaminant. Decision Support Systems (DSSs) are developed to help decision makers to deal with complex management crises, through the systematic structuring and evaluation of decisions, and through providing easy-to-use and integrated tools for information elaboration and display. We reviewed various DSSs developed for toxic substances in aquatic ecosystems, and suggested a conceptual framework which is best suited to the management of such issues within Korea. It may assist stakeholders with their decision making process, and in the achievement of a consensus on water management solutions.

In this paper, the function factors contributing to ITA/EA functions in their organizations, are suggested. Also the reasons to the construction of IT governance system and their effects on the their organizations are discussed and the relationships are verified by empirical model. From the survey, the data of the 227 respondents were collected and regression analysis was performed for validating the research model. ITA/EA functions consist of the IT infrastructure systemization, ITA/EA business process support, IT investment efficiency factors. And the factors of IT resource and performance management, IT process management, IT service management are included to IT governance. The main analysis results described significantly are shows as follows. At first, IT resource and performance management factor is effected by the ITA/EA business process support factor and IT investment efficiency factor. In similarly, IT service management factor is also affected by the factors such as ITA/EA business process support, IT investment efficiency, and IT infrastructure systemization. In additional analysis, IT investment efficiency factor in official sectors, ITA/EA business process support factor in private sectors respectively are described as the significant factors on the IT governance.

Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

Objectives : This study was performed to investigate the health status and social support among elderly living alone with restricted daily functions using the data of the "2014 the Korean Elderly Survey". Methods : Data on 2,407 elderly living alone were drawn and statistically examined using a t-test, an ANOVA, and a multiple regression analysis. Results : The study found that first, the elderly living alone with restricted daily functions comprised 22.1% of the total elderly living alone, and those who were older elderly, illiterate, with low-income, having poor nutrition management, and with a poor health status. Second, among the elderly living alone with restricted daily functions, there was a group with very little support from the family and only 14.0% were covered by long-term care insurance. Third, the life satisfaction of the elderly with restricted functions was lower than that of the non-restricted elderly, and was affected by income, health conditions, depression, access to senior welfare centers, and communication with others. Conclusions : The elderly living alone with restricted daily functions have serious health risks and social support, and hence they should be provided with more proactive support for life, health care and social care to live independently within their communities.

This study aims to examine the impact of accessing industrial factors in enhancing business performance with special reference to Muslim women entrepreneurs in Sri Lanka. Industrial factors are industrial resources available to Muslim women entrepreneurs in Sri Lanka and it was measured using the dimensions of resource accessibility and government and non-governmental support. A structured questionnaire was used to collect data from 260 women entrepreneurs from the Muslim community who are registered with the chamber of commerce in the three districts of the Eastern province of Sri Lanka, using a simple random sampling technique. Structural Equation Modeling with AMOS was used as the data analysis technique. The structural model showed that resource accessibility had a significant and positive relationship with business performance, whereas government and non-governmental support did not significantly influence business performance. Especially, Muslim women entrepreneurs in Sri Lanka do not show interest in getting support such as finance, training, and other necessities from government and non-government organizations as well as business development support agencies. Trade chambers and decision-making authorities may use this finding to gain insights and develop strategies to enhance the business performance of women entrepreneurs.
