  • Generating an action plan and obtaining commitment to achieve it is desired in organizations, but not always achieved. Whatever the reason, there is a room for an improved approach to decision making, so that people can arrive at a common understanding of a problem and commitment to action. Those are the purposes of a Decision Conferencing(DC). A DC, one example of single workstation-based GDSSs, is a two-day session attended by a group of people who attempt to resolve important issues of concern to their organization with the help of group facilitation techniques and decision analytic computer modelling. The interchange of differing perspectives on the issues is encouraged by the facilitator who attends to group processes but does not contribute to the content of discussions. Decision analysis provides a variety of structures for modelling the differing perspectives. Information and value judgements are incorporated in these models, whose results usually reveal new, higher-level perspectives on the issues. Information technology is needed to combine the part of the model and to facilitate on-the-spot replay of results. The experimental case study in this paper shows that how a DC can help a Korea's trading company to develop new, corporate level resource allocation strategies which are based on improved consensus among competing participants.

  • The purpose of the study was to present a model of WHO Health Promoting School easily applicable to small-sized schools in rural areas. Methods: The study analyzed data of 11 small-sized schools in rural areas selected from 85 health promoting schools, an initiative led by the Ministry of Education from 2012 to 2014. Results: Through the analysis, the study found out the operation process of health promoting schools consists of five stages: system development, needs survey & survey on current status, school health policy development, program development & execution, and evaluation. In addition, the study was able to discover three key factors in operating health promoting schools: connection with curriculum, connection with community, and consensus among members. While it turned out the schools were following operation manuals faithfully, the biggest problem with operation was that the stages of needs survey, priority setting, and core task development were not closely coordinated. Conclusion: Although the model suggested in the study fails to reflect the characteristics of small-sized schools in rural areas, it is close to a universal model which could serve as a guideline when regular schools adopt the system of health promoting schools.

  • Purpose: This study was intended to identify the competency model for korean health teachers. In order to enhance job effectiveness and talent development of health teachers in schools, this study would provide policy makers and school administrators with a competency model to be used as a valid and reliable tool for selection, development, and appraisal of health teachers. Methods: This study used three-round Delphi technique, which was a series of surveys to obtain a consensus of experts in school health and health education. 31 experts were finally involved in Delphi panel, which consisted of professors, administrators, and school teachers. Results: This study found that the competency model of health teachers was composed of fourteen competencies and 75 performance indicators. The fourteen competencies were as follows: consulting and teaching competency, students understanding competency, health problem solving competency, health assessment competency, relationship building competency, information management competency, curriculum management competency, teaching activity competency, writing competency, professional expertise competency, health business management competency, self control competency, school commitment competency, and achievement orientation competency. Conclusion: Based on the results of this study, policy makers and school administrators would be able to use the competency model as a tool of new health teachers selection, existing health teachers appraisal, and new and existing teachers training and education. Future research needs to classify the levels of each performance indicator as a kind of behavior indices.

  • Molecular docking is a critical event which mostly forms Van der waals complex in molecular recognition. Since the majority of developed drugs are small molecules, docking them into proteins has been a prime concern in drug discovery community. Since the binding pose space is too vast to cover completely, many search algorithms such as genetic algorithm, Monte Carlo, simulated annealing, distance geometry have been developed. Proper evaluation of the quality of binding is an essential problem. Scoring functions derived from force fields handle the ligand binding prediction with the use of potential energies and sometimes in combination with solvation and entropy contributions. Knowledge-based scoring functions are based on atom pair potentials derived from structural databases. Forces and potentials are collected from known protein-ligand complexes to get a score for their binding affinities (e.g. PME). Empirical scoring functions are derived from training sets of protein-ligand complexes with determined affinity data. Because non of any single scoring function performs generally better than others, some other approaches have been tried. Although numerous scoring functions have been developed to locate the correct binding poses, it still remains a major hurdle to derive an accurate scoring function for general targets. Recently, consensus scoring functions and target specific scoring functions have been studied to overcome the current limitations.

  • 본 논문에서는 두 영상간의 대응관계로부터 퍼지 분류기법을 이용한 강건한 카메라 동작 추정 방법을 제안한다. 제안한 방법에서는 이상치가 존재할 때 정확한 카메라 동작을 추정하기 위하여 대표적인 강건 예측기법인 RANSAC 알고리즘을 사용한다. 그런데 RANSAC은 사전에 결정되는 이상치의 비율에 따라 정확도가 좌우되는 샘플링 문제점을 가지고 있다. 이러한 문제점을 개선하기 위해 샘플링 시에 퍼지 분류기법을 이용하여 전체 샘플을 좋은, 모호한, 나쁜 샘플로 분류한다. 그런 후에 좋은 데이터에 대해서만 샘플링을 수행함으로써 이상치 제거에 대한 정확도를 향상시킨다. 실험에서는 호모그래피 계산에 대한 성능을 비교함으로써 제안한 방법의 우수함을 보인다.

  • As the Law on the Prevention of Domestic Violence was enacted in Korea, it has become necessary to work on how to intervene effectively in Korean men who batter. The purpose of this study is to establish the framework of the intervention model which is relevant to Korean wife-batterers. In the States, the psychoanalytic model, cognitive-behavioral model, and feminist model are most widely used with men who batter. As yet, the consensus on which model is most effective has not been reached. In this study, each model is reviewed briefly. And then it is suggested that in the light of Korean culture the educational model is more relevant than therapeutic model. Several points are also suggested, which need to be considered when feminist model is used in Korean culture. It is also insisted that the integrated model based on ecological theory is necessary to intervene effectively in such a multi-dimensional problem as domestic violence. For the group intervention, it is suggested to use educational model primarily and to use therapeutic model complementarily. Based on the framework suggested in this study, to develop the specific structure of the program, to implement it, and to test its effectiveness will be the tasks of the future researches.

  • Purpose: The aim of this study was to exam differences in awareness and ethical attitudes associated with Do-Not- Resuscitate (DNR) among emergency department's team. Method: The participants in this study were 402 emergency department's team working in the 41 hospitals. The data was collected by using "awareness measuring tool" by Kang (2003) and "ethical attitudes measuring tool" by Ko (2004) from May 1 to September 15, 2009. Collected data were analyzed by descriptive statistics, t-test, Pearson correlation coefficient using SPSS WIN 14.0 program. Results: 74.4% of subjects was responded that they had never been educated about DNR, but 73.9% of subjects was responded that they had experienced DNR in the emergency room. The majority of subjects responded that the patients and their families should make a decision about the DNR. There was a difference in an appropriate time for explanation of DNR among emergency department's team. There was a difference in ethical attitudes associated with Do-Not- Resuscitate among emergency department's team. Conclusion: For a professional and systematic approach to the problem, DNR guideline sufficient to elicit a social consensus is needed.

  • In the 2000s, financial exclusion of low-income people emerged as a major social problem in South Korea. Microcredit business was first introduced by NGOs to help the poor overcome poverty while the Korean government soon chose to initiate microcredit policies to assist financially marginalized low-income people as a key policy measure to alleviate social inequality and revitalize economy. Unlike the initial expectation that state intervention in microcredit industry would be more effective, the outcome has been much less impressive. This paper aims to examine the poor performance of state-led microcredit in South Korea during the period of Lee Myung-bak administration by employing the concepts of state autonomy and capacity. It finds that the state autonomy, a key characteristic of a developmental state, was high in the sense that the funds had been raised in the face of strong resistance from private financial institutions. Lack of state capacity such as low technocratic expertise and politicization of microcredit policy, however, turned out to be a major stumbling block to the state-led microcredit in South Korea. This study shows that although the Korean government still has strong willingness to intervene in the financial market even in the face of interest groups' opposition, the eventual success of state action largely depends on its capacity to effectively implement financial policies.

  • This research aims to analyze the external activities of local governments in South Korea from the perspective of the developing trends in city diplomacy, contrary to the conventional and narrow concept regarding local government's international exchange and cooperation as a public diplomacy. In detail, this research intends to illustrate the following: first, to differentiate South Korean local governments' growing commitment to international affairs from public diplomacy; second, to highlight the integration of public diplomacy with other forms of diplomacy within the framework of city diplomacy. This research argues that city diplomacy in South Korea has gradually shown the following three trends and characteristics. First, South Korean local governments have recognized the importance of participating in multilateral diplomacy via city networks to find compelling solutions to non-traditional and transnational security threats. They perceive this external activity as an opportunity for policy sharing and problem-solving with foreign partners. Second, local governments in South Korea have been fostering various ways to institutionalize their involvement in foreign affairs and organizations, such as amendments to related laws and the launching of task forces, to pursue so-called sustainable and systematic international exchange and cooperation. Lastly, South Korean local governments have constructed multiple channels and multilevel governance in the form of public-private partnerships to enhance policy expertise and cope with diverse agendas.

  • The purpose of this study is to review the proposed solutions to the Blockchain trilemma put forward by various research scholars and to draw conclusions by comparing the findings of each study. We found that the models so far developed either compromise scalability, decentralization, or security. The first model compromises decentralization. By partially centralizing the network, transaction processing speed can be improved, but security strength is weakened. Examples of this include Algorand and EOS. Because Algorand randomly selects the node that decides the consensus, the security of Algorand is better than EOS, wherein a designated selector decides. The second model recognizes that scalability causes a delay in speed when transactions are included in a block, reducing the system's efficiency. Compromising scalability makes it possible to increase decentralization. Representative examples include Bitcoin and Ethereum. Bitcoin is more vital than Ethereum in terms of security, but in terms of scalability, Ethereum is superior to Bitcoin. In the third model, information is stored and managed through various procedures at the expense of security. The application case is to weaken security by applying a layer 1 or 2 solution that stores and reroutes information. The expected effect of this study is to provide a new perspective on the trilemma debate and to stimulate interest in continued research into the problem.
