This study is intended to identify the motivations for seeking child care credentials through online education and factors influencing the career decision-making. The study was conducted among students taking child care courses online, and data was analyzed through t-test, F-test, Scheffe posteriori test, and hierarchical regression analysis. The findings are as follows. 1) Motivation for seeking the credentials varied depending on background variable. Livelihood was a stronger motivation for low-income group than higher come group. Self-realization desire was a stronger motivation for the group with low education level than the group with higher education level. 2) Age affected the participants' career decision-making. The younger they were, the more dependent they were on other people's advice. 3) Different variables influenced the students' rational, intuitional, and dependent career-decision making. Factors influencing their rational career decision-making were age, motivation to acquire the credentials for making a living, and motivation for building a better future. For intuitional career decision-making, age affected the decision. For dependent career decision-making, motivation to seek credentials for making a living was an influencing variable.

현재 그리고, 미래의 지속가능한 수자원 확보를 위해 수자원 계획 및 관리에 관한 제반 문제는 기술적인 측면과 사회적인 측면에서의 위험요소들에 대한 불확실성이 고려되어야 할 뿐만 아니라 이와 관련된 다양한 집단들의 이해관계도 상호작용하기 때문에 문제해결을 위한 다양한 기준과 내재적 갈등이 상존한다. 이에 본 연구는 농업용저수지의 연계운영 및 관리를 위한 다기준 의사결정시스템 구축을 하고자 하였으며 환경여건, 지형여건, 홍수위험도, 주민호응도, 용수수요량을 고려하여 농업용저수지의 연계운영에서 다수의 의사결정 요소들에 대한 가중치를 산출하였다. 이는 기존의 우선순위에 의한 용수배분이 최하순위의 용도나 지역에서 모든 물 부족분에 대한 위험을 부담하는데 반하여 의사결정 요소들의 상대적 가중치에 의한 용수배분은 전체 용도와 지역의 용수배분에 대한 위험이 분산되므로 보다 합리적인 것으로 판단된다.

This study alms to perform Business Process Reengineering and to develop tourism statistics information system through the development of tourism statistics process design supporting tool. With this tool, we can manage tourism statistics systematic and integrated. Also it offers a tourism decision making supporting tool. Tourism statistics process design supporting tool consists of information provider, information maker, and information user. This tool can improve bossiness process, and rationalize system architecture. 49 business processes were designed and a database which connected with outside system was designed by this supporting tool. By these means, this tool provide more reasonable and effective decision making tool, when it comes to plan tourism development.

This paper presents the application of fuzzy set theory in multi criteria decision making (MCDM). FAHP (Fuzzy Analytic Hierarchy Process) method was used to rank alternatives to find the most reasonable and efficient way of agricultural reservoir water resources assessment. 6 criteria and 10 subcriteria had been identified and compared to secure agricultural water resources. Fuzzy numbers and linguistic variables were presented to address inherently uncertain or imprecise data. Comparison analysis of decision making method was also carried out to find a way of suitable decision making and validity of FAHP was discussed.

Korean government is investing 1.8 billion won on infrastructure and investment on PPP projects constitutes 16.3%. This phenomenon is to promote private investment as well as lessening government burdens of public budgeting. However, the only criterion to be considered is government financial status in selecting public or private highway investment projects. So systematic decision support model is required in choosing public or private highway investment projects. So, this paper suggests a systematic decision support model for deciding public or private highway investment at the early stage of project planning. Furthermore, this paper identifies key decision variables with respect to economic, politic, project management criterions based on the related literatures and feedbacks from experts. This paper analyzed 30 cases of government investment and PPP projects and got the survey result from highway specialists. As a result, this paper presents an interval with respect to economic criteria using mean and standard deviation and a logistic regression equation which can predict the possibility of PPP project. Through this study, decision maker of central or local government can decide public or PPP highway project more systematically and reasonably.

최근 들어 협상을 지원하기 위한 시스템의 개발이 폭넓게 연구되고 있으며 특히 전자 상거래에 있어서는 온라인에 의한 협상 지원 시스템이 사용되고 있다. 그러나 대부분의 시스템은 사람에 의한 직접 협상으로 의사결정을 지원하고 있음으로 인해 사람에 의하지 않고는 시스템을 수행하거나 실행시키는 것은 불가능하다. 따라서 자동 협상을 지원하는 시스템에 대한 연구가 활발히 진행이 되고 있는 상황이다. 최근에는 에이전트를 기반으로 하는 연구가 이루어지고 있으며 에이전트는 작업흐름 관리나, 이메일, 전자상거래, 데이터 수집을 위해서 많이 사용하고 있다. 하지만 많은 연구들은 전자상거래 문제를 복잡한 의사결정 문제로 보고 있으며, 문제 해결을 위한 객관적인 요인들뿐만 아니라 주관적인 요인들을 고려한 합리적이고 지능적인 의사결정을 지원하는 방법에 대한 연구는 부족한 실정이다. 본 논문에서는 전자상거래에서 자동화된 협상지원시스템을 개선하기 위하여 아규먼트 추가시 속성의 가중치를 고려한 자동협상지원 시스템을 제시하고자 한다.

This study was intended to examine how the job stress of enterpriser affects decision quality when they make rational decision making, and to empirical analysis on whether decision quality can be enhanced through corporate network and absorption capacity. For this purpose, 356 survey data were collected from small business enterpriser and analyzed using SPSS v.25 and AMOS v.24. Studies have shown that among job stress, challenging stress has positive(+) influence on decision quality, disturbing stress has negative(-) influence on decision quality, and both corporate network and absorption capacity have positive(+) influence on decision quality. In addition, challenge stress and hindrance stress have been shown to have a positive(+) influence on decision quality through corporate network and absorption capacity. These findings confirmed that the challenge factors of job stress had a positive effect on decision quality, and confirmed that the corporate network and absorption capacity were important factors in enhancing decision-making products. As such, conclusions were discussed and implications and directions for follow-up studies were presented.

에너지 해외 의존도의 경감, 그리고 국제적인 환경규제에 대처하기 위하여 신재생에너지 가운데 하나인 소수력의 개발이 에너지문제의 대안으로서 부각되고 있다. 일반하천에서 소수력의 성공적인 개발을 위해서는 기존의 수자원 개발 계획과 마찬가지로 경제성을 기초로 한 자원의 효율적인 이용 및 개발에 따른 인문 사회 환경적 영향 등과 같은 체계적인 적지분석이 선행되어야 한다. 그리하여 본 연구에서는 소수력 개발 대상 지점에 대한 유황 및 지형분석을 위해 SWAT 모형과 GIS TOOL을 이용하였고, 소수력 모의발전 및 경제성분석에 의해 최적규모를 결정하였다. 그리고 AHP 방법에 의한 평가항목의 가중치 결정 및 대안 별 평가에 의해, 보다 합리적인 의사결정을 하고자 하였다. 이러한 일련의 과정을 금강 보청천 유역에 적용하였고, 총 7개의 지점에 대한 개발 우선순위를 도출하였다.

The purpose of this study is to investigate a decision making support system for the effective information management. Decision making theory is reviewed and problems are discussed. A model is suggested through the computing of expected monetary value in decision tree technique. The expected monetary value is computed by 1 inking the probability theory with chance node. The selection of right expected monetary value and expected value of perfect information will make great advance the present system. It is concluded that expected monetary value and expected value of perfect information in decision tree techniques will make great aids to advance information management system.
