Credibility theory has provided with a useful tool the assignment of weighting factor that reflects the credibility of the observed individual and collective experience to secure fair experience rate-,making. We review credibility models which can effectively estimate risk premiums using credibility theory, and suggest an empirical Bayed model based on the collective statistics to estimate the structural parameters. To illustrate the use of evolutionary models, the models are applied to the actual data, such as loss ratio, claim frequencies and severity, in the Korean automobile insurance. Also the possibilities of generalizations and applications of empirical models are discussed.

Collective intelligence can be an influential factor of decision-making based on collaboration and information exchange between individuals. Our study explores whether collective intelligence can mitigate the loss aversion effect, bias and error in human judgment, and collective intelligence in online communities can reduce the loss aversion effect. Our community settings display both individual-level and group-level loss aversion effect, investigate effective collective intelligence characteristics like investment commitment, participant experience. Using a multi-method approach our research comprises a web-based experiment with 100 participants investing 3 situations from a real-world community, data from a survey measuring loss aversion behavior of participants. The results suggest the loss aversion effect mitigates under the online-circumstance. Overall, our results suggest that, while collective intelligence mitigates the loss aversion effect, participants do not transfer these results to other settings.

The purpose of this study was to analyze the influence of collective self-esteem on teachers' job stress. For the study, 223 teachers in elementary school, junior high school, and high school were selected and data on teachers' background variables, collective self-esteem, and job stress were collected. The relationship between variables was analysed by using multiple regression analysis. The results were as follows: The job stress of teacher was significantly different according to teacher's gender, school level, and career experience. When the influence of background variables was controlled and multiple regression analysis was performed, the group self-esteem of teachers had a great influence on mitigating the perception of job stress. Particularly, it was shown that private collective self-esteem and importance to identity are the most important factors in mitigating job stress perception among the sub-variables of collective self-esteem. These results showed that it is an important task for our society to find an effective way to elevate the teacher's collective self-esteem. Teachers' collective self-esteem is expected to play a positive role not only in mitigating job stress but also in enhancing self-fulfillment and personal self-esteem of teacher.

현재까지 모바일 게임 사용자 연구는 개별 콘텐츠의 재미, 중독성, 편의성과 같은 1차적 정서를 분석하는 차원에 머물러 있다. 그러나 스마트폰의 확산 이후 사용자들의 멀티태스킹이 보편화되면서 사용자의 게임 콘텐츠 경험은 복잡해지고 있다. 따라서 다양한 행위를 동시에 수행하는 사용자의 관점에서 모바일 게임에 대한 보다 깊이 있는 분석이 필요한 상황이다. 본 연구는 집단 감성의 관점에서 모바일 게임 사용자들의 연결된 심성 모형을 포착하고자 했다. 이를 위해 사용자들의 비의도성과 의도성을 동시에 포착할 수 있는 소셜 데이터 분석을 실시했으며, 그 결과로 서비스의 교차 소비, 정보 추천방식의 다양화, 관계 기반의 과제 경험을 주요 이슈로 제시했다.

Education for the future society should emphasize the experience of sharing, coexisting, and solving problems in cooperation with each other in the community. Accordingly, in addition to the problem-solving capability, which is the ultimate goal of mathematics education, it is necessary to strengthen the capability to solve unstructured problems through collaboration. This study attempted to suggest that solving complex problems through collaboration is used in school classes or gifted education by introducing polymath that solves problems using collective intelligence. Accordingly, a target problem was set and an example of polymath in which community members exert each other's intelligence to solve the problem. In addition, by investigating the perceptions of students who have experienced polymath, positive aspects and improvements of polymath were suggested. Through this, this study can contribute to revitalization of mathematics teaching and learning methods using collective intelligence.

阿拉伯人联合抵制丹麦产品, 澳大利亚人联合抵制法国产品, 而中国人厌恶日本产品, 这些是国家间的敌对行为影响消费行为的案例. 敌意文献中已考查过消费者对其他国家敌对行为的反应, 以及这种敌意如何影响消费者对敌对国家产品的态度和倾向. 例如, 中国消费者不愿购买日本产品, 是由于日本人在第二次世界大战中的暴行, 以及不平等的经济往来(Klein, Ettenson and Morris 1998). 然而在市场营销文献中, 却没有考查过那些对他国实施敌对行为的国家消费者的反应, 这些敌对行为是否会影响他们购买受害国产品的态度. 社会心理学文献认为, 消费者面对这样的敌对行为时, 会产生一种集体犯罪感. 集体犯罪感源于当组织成员认为组织要对伤害其他组织的行为负责时所产生的痛苦感(Branscombe, Slugoski, and Kappenn 2004). 案例包括美国人由于美军在Abu Ghraib监狱的暴行而产生犯罪感(Iyer, Schamder and Lickel 2007), 荷兰由于过去对印度尼西亚的占领而产生犯罪感(Doosje et al. 1998). 本研究的主要目的是考查当国家成员对他国有敌对行为时消费者的感知, 这种感知是否会影响他们对敌对国家产品的态度. 更准确的说, 本研究的目标之一是考查集体犯罪感的感知前提, 以及当国家成员对他国有敌对行为时, 人们的情绪反应. 另一个目标是考查集体犯罪感如何影响消费者对敌对国产品的感知和倾向. 如果集体犯罪感能起到明显的预言作用, 敌对国双方的公司可能会从这类不幸的事件中受益. 本研究利用了由Klein, Ettenson and Morris (1998)提出并经Klein (2002)发展的敌意模式. Klein发现美国消费者对日本人怀有敌意, 起因是二战期间的事件(如日军偷袭珍珠港)和近年来日本的经济威胁. 因此本研究认为, 二战间的事件(如广岛长崎的原子弹爆炸)可能导致美国消费者的集体犯罪感. 曾有过一系列的三个假设, 第一个假设关于集体犯罪感的前提. 之前有研究认为当消费者感知到侵害造成的非法伤害, 并且认为侵犯者来自的国家应为此负责, 集体犯罪感就产生了(Wohl, Branscombe, and Klar 2006). 因此提出下列假设: 假设1a: 感知到的伤害非法性越高, 集体犯罪感越强烈. 假设1b: 责任越大, 集体犯罪感也肯定越强烈. 第二个和第三个假设关于集体犯罪感对倾向日本产品的影响. Klein (2002)发现对日本的敌意越强, 相比较韩国产品对日本产品的倾向越小, 但相比较美国产品对日本产品的倾向并未变小. 这些结果说明集体犯罪感存在时, 消费者在购买日本产品和韩国产品时会更倾向于前者, 但在购买日本产品和美国产品时并未受影响. 假设2: 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 但与购买日本产品的倾向大于美国产品无关. 假设3: 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 并且对产品的判断和敌意保持不变. 有过一个实验测试这个假设. 使被调查者面临发生在二战中的敌对事件, 从而产生非法伤害和责任. 该实验由一家美国的消费者调查小组收集数据, 将调查对象随机分配到低等级责任和违法情况(n=259)或高等级责任和违法情况(n=268). 测试假设关系时, 运用到潜在变量结构方程模式(LVSEM). 第一个假设得到了支持, 美国人因二战中对日本人的伤害而产生的伤害非法性和责任都对集体犯罪感有积极影响. 第二个假设也得到了支持, 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 但与购买日本产品的倾向大于美国产品无关. 最后, 第三个假设也得到了支持, 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 同时还影响人们对日本产品的判断和敌意. 由这些研究的结果可得出结论. 第一, 伤害的非法性和责任是集体犯罪感的前提. 第二, 当消费者面临来自敌对行为目标国家的产品和其他外国产品之间的选择时, 会受到集体犯罪感的影响. 但当他们面临来自敌对行为目标国家的产品和本国产品时, 不受集体犯罪感的影响. 这一结果意味着当竞争对手来自国外时, 利用集体犯罪感对那些受到敌对行为的国家的公司是可行的, 但当竞争对手来自国内时则不可行.

Over the last decade, some Korean enterprises have emerged to become global players in their specialized products. How have they achieved such tremendous technological progress in a short period of time? This paper explores that question by examining the characteristics of technological innovation activities at major Korean enterprises. The paper begins with a brief review of the stages of economic growth and science and technology development in Korea. Then, the existing literature, explaining the Korean innovation model, is analyzed in order to establish a new framework for the Korean innovation model. Specifically, Korean firms have experienced three sequential phases, and thus, the Korean model, at the firm level, can be coined as "path-following," "path-revealing," and "path-creating." Then, the stylized facts in the first phase (path-following) and the second phase (path-revealing) are discussed, in the context of empirical evidence from the areas of memory chips, automobiles, shipbuilding, and steel. In terms of technology development, the Korean model has evolved as "collective learning" in the first phase, "collective recombination" of existing knowledge and technology in the second phase, and is assumed as "collective creativity" in the third phase. Ultimately, all three can be classified as "collective creation". Korean firms now face a transition in the modes of technological innovation in order to efficiently implement the third phase. To achieve remarkable progress again, as they did in the past, and to sustain the growth momentum, Korean firms should challenge new dimensions such as creative technological ideas, distinctive technological capabilities, and unique innovation systems -- all of which connote 'uniqueness'. Finally, some lessons from the Korean technological innovation experience are addressed.

Background: Presenteeism is closely related to work performance, work quality and quantity, and productivity at work. According to the job demand-control-support model, job demand, job control, and support play important roles in presenteeism. The present study investigated job characteristics profiles based on the job demand-control-support model and identify the association between job characteristics profiles and presenteeism. Methods: This secondary data analysis used the Sixth Korean Working Condition Survey, a nationwide cross-sectional dataset. The study included 25,361 Korean wage workers employed in the workplace with two or more workers. Participants were classified into four job characteristics profiles based on the job demand-control-support model, using latent profile analysis, and logistic regression was performed to examine the association between study variables. Results: Overall, 11.0 % of study participants reported experience of presenteeism in the past 12 months. Age, sex, location, monthly income, shift work, work hours, health problems, and sleep disturbances were significantly associated with presenteeism. The rate of presenteeism was the highest in the passive isolate group. The passive collective, active collective, and low-stain collective groups had a 23.0%, 21.0%, and 29.0% lower likelihood of experiencing presenteeism, respectively, than the passive isolate group. Conclusions: The job demand-control-support profiles and the risk of presenteeism were significantly associated. The most significant group that lowered the experience of presenteeism was the low-strain collective group, which had a low level of demand and high levels of control and support. Therefore, we need a policy to reduce job demand and increase job control and support at the organizational and national levels.
