지식경영의 기본적인 목적은 조직 구성원간에 효과적으로 지식을 공유 하도록 하는 것이다. 지식 경영에 관련된 많은 연구들은 지식 공유가 필요한 상황 및 지식 공유를 촉진시키는 조직 환경에 집중해왔다. 그러나 조직에 속한 개인들이 누구와 어떻게 지식을 공유하는 것이 가장 효과적인지에 대해서는 충분한 연구가 이루어지지 않았다. 본 연구의 첫 번째 주제는 지식 전달자와 지식 수용자간에 지식을 주고 받을 때 전달되는 지식 속성의 질을 결정하는 요인을 규명하는 것이다. 특히 본 연구는 프로젝트를 수행하는 개인간의 지식 공유에 초점을 맞추고 있다. 본 연구의 두 번째 주제는 지식 속성의 구성과 지식 속성이 지식 효용 및 업무 결과의 물리적 그리고 심리적 측면에 어떠한 영향을 미치는 지를 규명하는 것이다. 본 연구는 기존 연구와 달리 지식 속성의 질을 지식 공유의 성공 여부를 결정짓는 중요 요소로 인지한다.

The most important points in the field of entrepreneurship research are new venture creation and behaviors for start-up venture. Most of past researches are limited to the formation of entrepreneurial intention, and researches on entrepreneurial activities, specifically nascent entrepreneurial behavior, have not been studied well. In this study, we view entrepreneurial process as gestation process from entrepreneurial intention to nascent entrepreneurial activities, and identify the moderating effects of cognitive style, which is the way of thinking about the information in entrepreneurial process. In addition, we find the moderating effects of cognitive style on the relationships between perceived barriers and support in environmental factors and nascent entrepreneurial activities. Subjects of this study are potential entrepreneurs. So we selected university students who are taking venture start-up course, conducted a survey, collected 367 questionnaires. In statistical test, we applied PLS-SEM for testing hypotheses because CB-SEM is too sensitive to test more than two moderating effects in th research model. As a result of the analysis, it was found that entrepreneurial intention, cognitive planning style, cognitive creative style, perceived support had a significant effect on nascent entrepreneurial behavior. The results of the analysis of the moderating effects of cognitive style which are the hypotheses in the research are as follows. First, the cognitive planning style did not have a significant moderating effect on the relationship between entrepreneurial intention and nascent entrepreneurial activities. Second, in the relationship between perceived barriers and nascent entrepreneurial activity, cognitive planning style did not have significant moderating effect, and cognitive creating style had significant negative moderating effect. Third, in the relationship between perceive support and nascent entrepreneurial activity, cognitive planning style had significant positive moderating effect, and cognitive creating style did not have significant moderating effect.

The study of loss aversion has progressed. Specifically, Brenner et al. (2007) distinguished between possession loss aversion (PLA) and valence loss aversion (VLA) and explained PLA is the loss of cash or spot goods (money, apartment) and that VLA is the loss of tentative value (opportunity of oversea study, coupon). Also, they explored how the tendency of loss aversion was different between when possession loss was salience and when valence loss was outstanding. But, in our everyday life, it is more common that people face some economic situation where the gain and loss between possession and valence are competing. And, in this situation, they usually choose a better option based on their ordinary mind-set or self-focus rather than on which option has more benefit. Therefore, present research is that whether the tendency of loss aversion is different based on one's ordinary self-focus. Concretely, after priming promotion focus vs. prevention focus, participants should decide whether present occupation changes or not when gain and loss between possession and valence compete (income increase but oversea study chance decrease or income decrease but oversea study chance increase). As a result, there are more rate of changing job in promotion focusing condition than prevention focusing condition based on positive change irrespective of possession or valence. This result can have implication for marketing, consumer and advertisement psychology.

The growth of the live commerce market allows you to conveniently and simply start live commerce anytime, anywhere with a smartphone. The use of smartphone services provides continuous communication and is used while feeling psychological attachment, and it leads to psychological attachment, self-consistency with consumers themselves, and self-identity. This study focuses on the motives and perceptions of consumers using live commerce. In other words, we will examine the relationship with service attachment through the moderating effect of self-efficacy and control focus tendency as consumers' personal and psychological characteristics. In other words, the tendency of regulatory focus, which determines the direction of behavior of consumers according to their motives and goals, affects the service attachment of live commerce. We believe that self-efficacy, which is personal confidence and belief that you can plan and execute on your own for the desired outcome in a given situation or task, will control this relationship. As a result of this research, consumers who highly perceive prevention focus were more likely to avoid negative consequences and pursue safety and obligations. Their attachment to live commerce services was stronger, offsetting their confidence and self-efficacy. When using live commerce services, the more they perceive that information acquisition is beneficial, the higher their belief, and self-efficacy, so service attachment, which is an emotional experience as well as a cognitive experience, is strongly formed for consumers with a preventive focus to avoid safety-seeking and negative consequences. Through the present research results, we believe that it will be helpful in operating strategies and management for companies and small business owners who want to understand the psychological behavior of consumers in using live commerce services.

One often thinks that those doing any activity on the Internet are likely to be addicted to it so that they tend to rather restrain the educational use of what the Internet can provide. However, the online edu-games deserve a good learning material which can not only provoke learners' interest but also draw out a smoother interaction between teachers and learners. Even the preliminary study on immersion verified that the Internet could work positively for the learners. Considering that online edu-games can be a useful tool for individual learning, more studies on immersion should be conducted focusing on the individualization in the future. This paper shows the differences among the components of learning immersion depending on the different individual cognitive styles in the online edu-games.

We have analyzed the science-gifted educational program (year 2002) at the Seoul National University in terms of its educational objectives, scientific models, and cognitive processes in scientific inquiry in order to provide insights into developing and improving science-gifted educational program. We assumed the following items as important factors for teaching scientifically gifted students: higher-order thinking skills involving synthesis domain in the educational objectives, highly abstract nature and complexity in the scientific models, cognitive processes of planning experiments in the cognitive processes in scientific inquiry. According to the analyzed results, the program has the following characteristics: (1) the rates of both higher and lower-order thinking skill domain in the educational objectives are similarly high, but the rate of synthesis domain is relatively low; (2) in the case of the scientific models, the rate of the multiple concepts and/or processes model is relatively low, while the level of the abstractness is relatively on average (3) cognitive processes of authentic scientific inquiry is not thoroughly reflected in the scientific inquiry activities, and very few cognitive processes of planning experiments factor is reflected. Therefore, we conclude in the synthesis domain in the educational objectives, multiple concepts and/or processes model, and cognitive processes of planning experiments should be especially reflected more on the science-gifted educational program in order to serve the needs of scientifically gifted students.

Objectives: The purpose of this study was to investigate whether longitudinal changes in positive and negative symptoms affect cognitive functioning in chronic schizophrenia. Methods: Sixty-eight patients diagnosed with DSM-IV schizophrenia were examined on two occasions over 6 months for symptoms and cognitive changes. Symptoms were measured by PANSS. Cognitive functions were examined for sustained attention, executive function, concentration and attention, and verbal memory and learning using Degraded Stimulus Continuous Performance Test, Wisconsin Card Sorting Test, Digit Span, and Rey Auditory Verbal Learning Test, respectively. Twenty control subjects were assessed to compare the cognitive scores of remitted schizophrenic patients. Results: Patients showed significant improvement in symptoms and all cognitive tests after 6 months treatments. Significant improvements in positive and negative symptoms did not predict improvements in any aspect of cognitive functioning measured. Normal controls performed significantly better than remitted schizophrenic patients on all cognitive tests. The results show no relationship between change in symptoms and change in cognition in chronic schizophrenia. Conclusion: We suggest that symptomatic and cognitive impairment may be a distinct construct. These findings highlight the importance of treating cognitive impairment in addition to the clinical symptoms of schizophrenia.
