This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

The importance of Entrepreneurship has been widely acknowledged by researchers and practitioners worldwide, however, the idea of Social Entrepreneurship is still considered to be an emerging area. Entrepreneurship is vital not only because of its economic impacts but also because it helps to address issues of poverty and welfare, where it can act as a catalyst for change. The importance of social entrepreneurship is that it serves to turn a profit and find success while helping others throughout the world. They know the power of social enterprise and are eager to serve the societal and economic benefits. This study aims to identify the level of orientation of youth towards social entrepreneurship in Pakistan. The study identifies the role of various factors that affect Social Entrepreneurial Orientation and is conducted following a quantitative research strategy and survey research design where data is collected from 302 individuals. Structural Equation Modelling was used to analyze the data and to test the hypotheses. The main finding of this research is that there is an increasing trend in the orientation towards social entrepreneurship. The exogenous variables namely Perceived Educational Support, Perceived Structural Support, and Perceived Relational Support were found to have positive and significant effects on the endogenous construct of Social Entrepreneurial Orientation.

The basic purpose of this study is to investigate how the traits of the buyer-seller transaction-relationship relate to relationship performance, including relationship performance explicitly in the proposed model. The traits examined include relational norm, formalization, market uncertainty, and relationship investment. It is hypothesized that relational norm and formalization have positive impacts on relationships performance while market uncertainty has a minus impact. In addition, it is hypothesized that relational norm has a positive moderating impact on the effect of relationship investment--the investment and efforts for maintaining a relationship to relationship performance. A mail-survey to the manufacturers of machinery and equipment about their relationships with the parts suppliers was performed. Data provided a strong support for the hypotheses. As hypothesized, relationship performance and formalization generally had positive impacts on relationship performance and formalization generally had positive impacts on relationship performance while market uncertainty showed negative impacts. Also, there is a good evidence for the positive moderating effect of relational norm to the impact of relationship investment on relationship performance.

Coping resources may be a crucial aspect in single mothers' and their childrens' adjustment. Using a survey data collected from 275 pairs of single mothers and their children, this study investigated the perceived effects of economic resoures, family relational resources, and social support on positive changes of both mothers and their children. Results revealed that both mothers and their children perceived positive changes of themselves and their children(mothers) relatively high. The degrees of positive changes of mothers were influenced mostly by family relational resources. In the same token, the degrees of positive changes of children were also affected by family relational resources. Overall, the findings suggested the importance of relational resources in explaining the positive changes of single mothers and their children.

본 연구는 직장인의 자기방어적/관계관여적 정서표현 양가성이 대인관계 스트레스에 영향을 미치는데 있어 사회적 지지와 인지적 정서조절전략의 매개효과를 알아보고자 하였다. 이를 위하여 2018년 8-9월에 걸쳐 직장인 413명을 대상으로 설문조사를 실시하였고, 수집된 자료는 SPSS, AMOS, Mplus 프로그램을 사용하여 기술통계, 상관분석, 구조방정식 모형검증을 비롯하여 매개효과 검증 분석을 실시하였다. 분석 결과, 자기방어적 정서표현 양가성 모형에서는 부분매개효과가 유의하였고, 관계관여적 정서표현 양가성 모형에서는 완전매개효과가 유의하였다. 자기방어적 정서표현 양가성 모형과 관계관여적 정서표현 양가성 모형 모두에서 정서표현 양가성과 대인관계 스트레스의 관계에서 사회적 지지와 정서조절전략을 거쳐 가는 이중매개효과가 유의한 것으로 나타났다. 이러한 연구는 직장인의 사회적지지에 대한 지각수준을 높이고, 적응적 인지적 정서조절전략을 사용하게 함으로써 대인관계 스트레스를 낮추는 방법을 모색하였다.

Knapsack problems represent many business application such as cargo loading, project selection, and capital budgeting. In this research we developed a knapsack problem solver based on Martello-Toth algorithm using a relational database management system on the PC platform. The solver used the menu-driven user interface. The solver can be easily integrated with the database of decision support system because the solver can access the database to retrieve the data for the model and to store the result directly.

This study investigates how relational activities within MNC network affect knowledge transfer and performance of subsidiary. We separated the possible relationships between headquarter and overseas subsidiaries by support level, interaction level, and conflict level, and compared the impact on knowledge transfer, and performance. To understand the knowledge sharing, development and performance, we use structural equation modeling to analyze data from subsidiaries in China.

본 연구는 학습 형식이 탐험과 활용이라는 양면적 조직성과에 미치는 프로세스에 관해 구성원들이 인지하고 있는 조직 지원과 관계 문화의 특성은 어떤 매개 또는 조절효과를 발휘하고 있는지 분석하였다. 본 연구는 고용노동부와 한국직업능력개발원에서 제공하는 인적 자본 기업 패널 조사를 활용, 설문에 응답한 548명의 데이터를 토대로 실증적으로 검증하였으며, 연구 결과는 다음과 같다. 구성원들에게 제공되는 형식 학습과 무형식 학습은 기업의 성과인 탐험 성과와 활용 성과에 모두 긍정적인 영향을 미치는 것으로 나타났다. 또한, 구성원들이 느끼는 조직 지원 인식은 형식 학습과 무형식 학습이 양면적 조직성과에 미치는 방향에 대해 완전매개, 부분매개 효과를 보이는 것으로 나타났다. 마지막으로 관계 문화는 무형식 학습이 조직의 활용 성과에 미치는 관계를 긍정적으로 조절해주는 중요한 영향을 미치고 있었다.

Most of expert systems use the text-oriented knowledge bases. However, knowledge management using the knowledge bases is considered as a huge burden to the knowledge workers because it includes some troublesome works. It includes chasing and/or checking activities on Consistency, Redundancy, Circulation, and Refinement of the knowledge. In those cases, we consider that they could reduce the burdens by using relational database management systems-based knowledge management infrastructure and convert the knowledge into one of easy forms human can understand. Furthermore they could concentrate on the knowledge itself with the support of the systems. To meet the expectations, in this study, we have tried to develop a general-purposed knowledge conversion tool for expert systems. Especially, this study is focused on the knowledge conversions among text-oriented knowledge base, relational database knowledge base, and decision tree.
