소비자의 집단 구성원에 대한 자아지각은 소비자 의사결정에 어떠한 영향을 미칠까? 집단소비자 상호간에 영향을 미치는 의사결정 상황이나 소비자 개인적 의사결정상황 등 의사결정 상황에 따라 다르게 영향을 미칠까? 본 연구는 소비자가 집단의식을 인식할 때 개인적 차원과 집단적 차원에서 행해지는 의사결정이 어떻게 이루어지는지를 검증하고, 이때, 소비자의 위험회피성향에 따라 소비자 의사결정이 어떻게 조절되는가를 2 가지 실험을 통해 밝히고자 하였다. 미국 오레곤 주립대학교의 아시아계 학생들을 대상으로 2 가지 실험을 실시한 결과, 집단의식을 지각한 소비자는 집단관련 의사결정은 물론 개인관련 의사결정에서도 긍정적 영향을 미치는 것으로 나타났다. 그러나, 위험회피성향의 조절효과에 대한 실험결과는 집단의식을 지각한 소비자와 집단의식을 지각하지 않는 개인적 소비자 모두 처벌에 관한 상황에서 형평성 선호와 협상적 대안을 선택하는 것으로 나타나 집단의식지각의 의사결정에 대한 위험회피성향의 조절효과는 부분적으로 나타났다.

비즈니스 조직에서 집단지성을 경쟁우위의 중요한 요소로 활용하는 사례가 증가하고 있다. 인터넷과 소셜 네트워크 서비스는 물론이고 위키와 같은 편집도구 등은 집단지성을 가능하게 하는 대표적인 정보기술이다. 그러나 집단지성은 전문가 지식에서와는 다른 품질의 문제가 제기되기도 한다. 따라서 본 연구에서는 집단지성의 품질에 영향을 주는 요인을 분석하는데 그 목적이 있다. 선행연구를 통해 집단지성의 품질에 영향을 주는 개인의 동기(love, money, glory, professional development), 집단특성(expertise, diversity, size), 집단지성의 도구(navigating, usefulness, agility, user preference) 차원에서 총 11개의 영향요인을 파악하였다. 조직 경쟁우위의 핵심으로 집단지성을 활용하는 대표적인 성공사례인 Threadless, InnoCentive, iStockphoto, Panda Security, Wikipedia를 분석하여 3개 차원에서 11개의 명제를 제안하였다. 사례분석의 결과, 개인의 동기, 집단특성, 집단지성을 위한 도구는 집단지성의 품질에 긍정적 영향을 주는 것으로 나타났다. 예를 들어, 개인적 동기가 뚜렷하고 다양한 특성을 지닌 다수가 참여할수록 소집단에서보다 더 잘 문제를 해결하고 있는 것으로 분석되었다. 따라서 집단지성의 품질을 개선하고 이를 통해 혜택을 얻기 위해서 조직에서는 다양성을 지닌 대규모 커뮤니티를 구성하고, 참여에 대한 동기를 부여하고, 적절한 집단지성의 도구를 선택하여 활용하여야 한다.

This study investigated the effect of the grouping method in cooperative learning applied to chemistry concept learning. Two grouping methods used were the HML (High-Medium-Low) and the HL/MM (High-Low/Medium-Medium) ability grouping. Three classes (N = 136) at a high school in Seoul were randomly assigned to the control and the treatment groups. Before instruction. the test of attitude toward science instruction, the perception questionnaire of learning environment consisting of three subtests (participation, conflict, and competition), and the questionnaire of self-esteem were administered, and a mid-term examination score was obtained. These scores were used as covariates. After instruction, the three tests administered before instruction and the conceptions test were administered. Two-way ANCOVA results revealed that there was a significant interaction between the treatment and the level of previous achievement. The low-level students in the HL/MM cooperative group performed better than those in the other groups. The cooperative groups, regardless of the grouping methods, exhibited more positive perception than the control group at participation subtest of the perception questionnaire of learning environment.

This paper exploited the data reported in BK21 program of professors' research performances and analyzed the effects of reputational concerns on professors' research performances. According to the established theory of reputation effects in incentive provision, a professor's research incentive gets stronger if one's ability is less known, and one's colleagues' abilities are better known. We confirmed this theoretical hypothesis of reputation effects. Moreover, we found that a professor's research incentive was larger under inter-generational grouping in terms of age distribution and homogeneous grouping in terms of ability uncertainty.

최근 국민소득수준의 향상을 따라 여름철 전력 수요가 폭증하므로 전력안정 공급을 위한 특별 대책이 필요한 실정이고 환경적인 측면이나 수용가 입장에서 만족스러운 새로운 냉·난방, 전기 공급시스템의 개발·적용이 필요하다. 선진국의 경우, 소규모의 집단에너지 공급이 주류를 이루고 있으며 특히 소규모 열병합 발전시 생산되는 전기, 지역난방열 이외에 냉방에 필요한 냉수를 중앙열원에서 동빌딩을 중심으로하는 구역형 집단에너지 시스템(Community Energy Supply System)등 소규모지역 난냉방 공급방식이 활성화되어 있으므로, 우리나라에서도 냉방/난방/전기부하 패턴 및 하절기 피크부하 경감에 대한 기여도 등을 고려한 경제성있는 최적시스템 구성이 가능한지 검토할 필요가 있다. 소규모 집단에너지사업은 대규모 사업과는 달리 적정 수요예측이 가능하므로 효율적인 초기 투자가 이루어질 수 있으며, 상업용 및 사업용 빌딩 등을 중심으로 부하밀도가 높은 구역을 대상으로 하명서 해당 부하패턴에 적합한 효율적인 시스템의 구성을 통해 수익성이 확보된다면 국가 에너지절약 및 한전의 여름철 전력 피크부하 경감, 대기 환경공해 감소, 도심 도시미관 향상 등의 사업효과가 기대된다. 본문에서는 이러한 소규모 집단에너지시스템 개요 및 국내외 공급 현황, 국내 적용환경, 적용 가능에너지 검토 열원시스템의 기본방향 등에 대하여 언급하고자 한다.

The purpose of this study was to investigate the effects of the group reward and cooperative skill training on science achievement and learning motivation of elementary students. 3 classes of the 6th grade students were selected from an elementary school in Busan. Group I took traditional cooperative learning (TCL), group II took cooperative learning with competitive group reward (GR), and group III was trained in cooperative skill (CS) before cooperative learning. Students were taught about 'weather forecast' for thirteen periods and problem-based learning steps were applied in each class. The results from this study were as follows: First, there was an interactive effect between the treatment and achievement level in the science achievement test scores. In the case of high-level students the group reward was more effective than cooperative skill training on the science achievement; on the other hand, in the case of low-level students the cooperative skill training was more effective than the group reward on the science achievement. Second, there was no interactive effect between the treatment and achievement level in the motivation scores.

This study aims to investigate the components of group writing through three steps of group writing course consist of collecting information, organizing information, and revision. A total of 19 pre-service teachers who took the science argumentation course participated in the group writing activity. They made up a group of four or five and chose one subject from among socioscientific issues for group writing. The discussion contents and writing were analyzed inductively to find the group writing components at every step. The results of the study are as follows: First, components in the step of collecting information were (1) sharing information (2) understanding information. and (3)judging information. Second, components in the step of organizing information were (1) categorizing information, (2) decentralization, (3) balancing information, and (4) reflection. The last, process components in the step of revision were (1) unification of form, (2) global review, and (3) improving readability.

This study aimed at investigating the effects of grouping participants in pairs according to their relative vocabulary proficiency on the incidental improvement of vocabulary knowledge. Forty six university students were divided into three groups (high-high(n=14), high-low(n=18), or low-low(n=14)) and took part in the study. They performed three vocabulary activities in pairs as extra-class works. Data were collected from one receptive vocabulary knowledge test scores before treatment and two posttest scores after treatment. The results showed that, unlike former study results, HL dyads acquired more vocabulary receptively and productively than HH or LL dyads did, which demonstrated that collaborative pair activity was conducive to the growth of vocabulary knowledge. Furthermore, not only higher proficiency participants in HL pairs made greater vocabulary gains than participants in HH pairs did but also lower proficiency participants gained more vocabulary than participants in LL pairs did. Based on these results, we discussed pedagogical implications.

This paper presents two cases of organizational studies and deals with the issue of the level of analysis in the study of organizational phenomena. The first study focuses on the individual level of analysis and examines the effect of a merit pay system on employee attitudes, In this study data were collected using questionnaires from 195 employees across 18 companies. Analyses were are performed using 195 questionnaires at the individual level of analysis. On the other hand, the second study focuses on the group level of analysis examines the relationship between transformational leadership and group performance. In this study data were collected using questionnaires from 320 employees embeded in 40 groups in an insurance company. The 320 questionnaires were aggregated by groups and analyses were performed based on the aggregated scores at the group level of analysis. The importance of the level of analysis in the study of organizational phenomena was discussed.
