고도의 지식 기반사회인 현대사회에서 과학적 지식과 기술 혁신은 개인과 사회, 그리고 국가의 경제 발전과 경쟁력을 위한 필수적 요소로서 자리매김해 왔다. 그러나 이와 동시에 줄기세포연구, 유전자조작기술 등 기술혁신에 따른 잠재적 위험성은 사회적 불안 및 갈등요소로도 작용하고 있다. 기술에 대한 불확실성이 증가하고 사회가 다원화하면서 과학기술정책의 의사결정과정도 기존의 톱다운 방식인 '거버먼트(Government)'에서 점차적으로 '거버넌스(Governance)로 옮겨가고 있다. 다양한 사회 구성원의 참여로 의사결정이 이루어지는 거버넌스는 복잡한 사회 현상들에 대한 다원적 접근을 가능하게 한다. 본고에서는 거버넌스, 특히 기술혁신과 관련된 리스크 거버넌스를 중심으로 과학기술지식을 기반으로 한 의사결정모델을 살펴보고, 글로벌 시대에 과학기술과 사회의 지속가능한 발전을 위한 거버넌스 체계를 모색해보고자 한다.

Background: Most studies on the national health insurance benefit expansion policy have focused on policy tools or decision-making process. Hence there was not enough understanding on how policies are actually implemented within the specific policy context in Korea which has a national mandatory health insurance system with a dominant proportion of private providers. The main objectives of this study is to understand the implementation process of the benefit coverage expansion policy. Unlike other implementation studies, we tried to examine both the process of implementation and decision making and how they interact with each other. Methods: Interviews were conducted with the ex-members of the Health Insurance Policy Review Committee. Medical doctors who implement the policy at the 'street-level' were also interviewed. To figure out major variables and the degree of their influences, the data were analyzed with Winter's Policy Implementation Model which integrates the decision making and implementation phases. Results: As predicted by the Winter model, problems in the decision making phase, such as conflicts among the members of committee, lack of applicable causal theories application of highly symbolic activities, and limited attention of citizen to the issue are key variables that cause the 'implementation failure.' In the implementation phase, hospitals' own financial interests and practitioners' dependence on the hospitals' guidance were barriers to meeting the policy goals of providing a better coverage for patients. Patients, the target group, tend to prefer physicians who prescribe more treatment and medicine. To note, 'fixers' who can link and fill the gap between the decision-makers and implementers were not present. Conclusion: For achieving the policy goal of providing a better and more coverage to patients, the critical roles of medical providers as street-level implementers should be noted. Also decision making process of benefit package expansion policy should incorporate its influence on the implementation phase.

본 논문은 손실값을 포함하는 불완전한 데이터를 처리하는 방법에 대해 논한다. 손실값을 최적으로 처리한다는 것은 학습 데이터가 가지고 있는 정보들에서 본래값과 가장 근사한 추정치를 구하고, 이 값으로 손실값을 대치하는 것이다. 이것을 실현하기 위한 방안으로 분류기가 정보를 분류하는 과정에서 완성되어가는 결정트리를 이용한다. 다시말해 이 결정트리는 전체 학습 데이터 중에서 손실값을 포함하지 않는 완전한 정보만을 C4.5 분류기에 입력하여 학습하는 과정에서 얻어진다. 이 결정트리의 노드들은 분류 변수의 정보를 가지는데, 루트에 가까운 상위 노드일수록 많은 정보를 포함하게 되고 말단 노드에서는 루트로부터의 경로를 통해 분류 영역을 형성하게 된다. 또한 각 영역에는 분류된 데이터 사건들의 평균이 기록된다. 손실값을 포함하는 사건들은 이러한 결정트리에 입력되어 각 노드의 정보에 따라 순회과정을 통해 사건과 가장 근접한 영역을 찾아가게 된다. 이 영역에 기록된 평균값을 손실값의 추정치로 간주하고, 보상 과정은 완성된다.

Purpose: The purpose of this study was to examine the differences of the process of change, decision making, self-efficacy and perception of subjective health according to the stages of exercise behaviors suggested by transtheoretical models among older adults. Method: The subjects consisted of 291 older adults. Trained research assistants interviewed the older adults using structured questionnaires. ANOVA analyses with post hoc test were used to examine the mean differences for each stage of exercise behavior using SPSS for windows. Result: The subjects were divided into five stages of exercise behavior: 24.4% precontemplation, 12.4% contemplation, 17.9% preparation, 12.4% action, 33.0% maintenance stage. There were significant differences in process of change, decision making, self-efficacy and subjective health perception according to the exercise stage of change. 'Self-liberation' and 'stimulus control' were important strategies for intention of exercise, while 'reinforcing management' for the actual practice of exercise. 'Self-efficacy' was an effective strategy to change older adults from pre-contemplation to preparation stage. Conclusion: For exercise intervention, older adults should be classified into groups according to their stages of exercise behaviors and provided effective individualized intervention depending on their stage.

In this study, we try to understand the role of online social recommendation and the similarity of preferences between the recommender and the recommendee on consumer decisions in the framework of the two stage purchase decision-making process. Applying construal level theory to our context, we expect that the role of social recommendation and the similarity of preferences would vary over the stages in the two-stage decision making process. To test our hypotheses, we collected the data through an incentive compatible experiment, and analyzed the data with nested logit model. As a result, we found that the role of online social recommendation varies over the stages. Consumers take recommendation from similar others at the stage of consideration set formation, but no longer consider it at the stage of final choice. Consumers take recommendation from dissimilar others at the stage of consideration set formation. At the stage of final choice, however, consumers avoid choosing the option recommended by dissimilar others. The results of our study enrich the understanding about the role of social recommendation, and have implication to marketing practitioners who attempt to make online social recommendation system more efficient.

Purpose: The aim of this study was to identify thinking strategies in the complicated decision-making process based on real patient-based data of triage nurses in the emergency department (ED). Methods: This study used the 'think aloud' method to collect data from 8 triage nurses from one general hospital ED in South Korea. The data were analyzed with protocol analysis using thinking strategies. Results: The triage process was divided into three stages. The first stage consisted of 8 thinking strategies, including searching for information. They used intuition based on directly observed concepts for identifying a crisis. The second stage consisted of 17 thinking strategies related to the decision-making process. They assessed patients and generated a hypothesis to try to understand their health problems through analytic thinking. The third stage consisted of 10 thinking strategies, including qualifying. They considered the situation of the ED and properly triaged the patients. During the triage process, they frequently used judging the value and searching for information on 17 thinking strategies. Conclusions: Triage nurses demonstrated various connected thinking strategies for each stage. Based on our results, further studies should be done to develop a triage education program.

The purpose of this study was done to explore the pregnant women's decision-making process about their infants feeding method. Data collection involved the in-depth unstructured interviews with 12 participants from January 1998 to January 1999. Data analysis was done by the grounded theory method. The 112 concepts, 29 sub-categories were confirmed in the analysis. The sub-categories were again grouped into 14 categories: expectation, situational condition, inevitability of breast-feeding, social recognition, self-awareness as mother, harmony, consideration, pursuit of ease, effect of external environments, lack of knowledge, hardening, the best choice, control, and bargain. " Adjustment through recognizing of motherhood" was the key category that was related to all categories. "Adjustment through recognizing of motherhood" was a process in which the mother became aware of mothering and sharing, and in which she considered herself or infant's needs and their priorities. This research will help nurse to understand mother's needs better. Therefore, nurse will be able to assist mother making the best decision for herself and her infant.

세계 각국은 지식재산권이 확보된 자국의 기술을 국제표준으로 제정하여 산업보호 및 해외시장 창출을 추구하고 있음에 따라, 우리나라도 국가 정책적 차원에서 효과적인 표준화전략을 수립하기 위해서 시장 및 이용자가 요구하는 기술 분야의 표준화 과제를 선정하고 우선순위를 정하여 선택과 집중전략을 운영하는 것이 필요하다. 표준화 분야의 우선순위를 결정하는 것은 학계, 연구계, 산업계, 정부 등의 이해관계가 존재하는 의사결정문제로 복수의 평가기준을 갖는 다기준 의사결정문제로 정의할 수 있다. 본 연구에서는 다기준 의사결정문제에 체계적인 이론과 절차를 제공하는 계층분석방법(AHP)을 이용하여 국내 민간 표준화기구인 한국정보통신기술협회에서 선정한 37개 표준화 분야에 대한 우선순위를 결정하였다.

The influence diagram is a new conceptual tool that can be used for structuring a strategic decision problem in decision analysis. It has a graphical representation of probabilistic dependence among variables in the decision problem. In this formal procedures for constructuring the influence diagram and for translating it into the corresponding decision tree are studied. An example that shows the power of the infuence diagram is shown.
