지식 정보화 사회에서 지식경영의 중요성이 부각되면서, 학계의 다양한 연구와 기업의 의욕적인 투자가 진행되어 왔다. 그러나 지식경영과 관련된 기존 연구들은 다음의 한계점을 드러내고 있다. 즉 기존의 연구는 조직 내 구성원의 관계와 같은 구조적인 부분에 한정되어 지식경영의 주체인 개인의 개성(personality)에 대한 고려가 부족하고, 또한 구성원들의 동기를 고취시키기 위해 경쟁을 유도하는 환경이 지식공유에 주는 부정적인 영향을 간과하고 있다. 따라서 본 논문은 첫째, '개인간의 관계를 바탕으로 한 지식 공유에 있어서 자존감(Self-esteem)과 성취지향성(Conscientiousness)이 어떠한 영향을 주는가?', 둘째, '경쟁을 장려하는 것이 지식공유에 도움이 되는가?' 라는 문제에 초점을 맞추고 있다. 본 연구에서 KAIST 테크노경영대학원의 특정 수업의 수강생 32명을 대상으로 쌍방관계 데이터(dyadic relational data)를 수집하여 다중회귀분석(multiple regression Analysis)을 수행한 결과, 자존감은 개인간의 지식공유에 음의 조절변수(negative moderator)로 작용할 것이라는 가설이 지지되었고, 성취지향성은 개인간의 지식공유에 있어서 양의 조절변수(positive moderator)로 작용할 것이라는 가설은 지지되지 않았다. 마지막으로 조직 내의 경쟁이 심화될수록 개인간의 지식공유는 감소할 것이라는 가설은 지지되었다. 본 연구는 기존의 연구들과는 달리, 자존감이 높은 인재에 대한 보다 새로운 시각이 필요하다는 점과 경쟁을 장려하는 지식 경영 방법론에 대한 재고가 필요하다는 것을 실증적으로 보여주고 있다.

유전체기판 위에 놓여있는 안테나를 엄밀히 해석하기 위해서는 파원의 위치를 따른 각 매질에서의 Green함수를 도출하여야한다. 그런데 이와 같은 Green함수는 Sommerfeld적분식으로 표현되기 때문에 적분의 수렴성이 좋지 않아서 수치계산시간이 길어지는 등 곤란한 점이 많다. 본 논문는 접지면이 없는 유전체 슬라브에 위치한 안테나를 해석함에 필요한 3층매질 Green함수를 도출하고, 파수공간에서의 Sommerfeld적분의 수렴성을 개선하는 방법으로 피적분함수로부터 수렴이 늦는 부분을 해석적으로 해결하는 Extraction법을 적용하여 수치계산시간을 단축하였다. 또한 파수공간의 무한적분을 함에 있어 적분로상에 존재하는 표면파 모드를 분석하고 이를 처리하는 방법을 제안 한다.

The purpose of this study was to investigate the components in friendship as reported by Korean children of School age Specially, four major aspects of friendship - definition of friendship, friendship formation, friendship expectation, and friendship termination were explored. The subjects of this study consisted of 600 elementary school children in Grades 1 through 6, 50 males and 50 females at each grade level. Based on Bigelow (1977) five open - ended questions were administered. First and second graders were interviewed individually while 3rd-6th graders replied to a questionnaire in class. For content analysis, responses of each child were coded into 22 categories and each category was assigned a score from 1 to 4 according to its frequency. The data were analyzed by factor analysis. The results showed that four major aspects of friendship in Korean children of school age were found to consist of four different factors. DEFINITION OF FRIENDSHIP was found to consist of the factors; 1) reciprocity of liking vs. helping 2) global evaluation vs helping 3) sharing and 4) common activities. FRIENDSHIP FORMATION was found to consist of the factors; 1) situational effects vs complex evaluation 2) structural dimension vs common activities 3) helping and 4) staring. FRIENDSHIP EXPECTATION was found to consist of the factors; 1) mutuality 2) common activities vs. loyalty & commitment 3) exclusive - dyadic activities vs. admiration (character) and 4) interactive a1truism. FRIENDSHIP TERMINATION was found to consist of the factors; 1) physical separation vs disappointment (character) 2) conflict 3) physical separation vs. psychological dimension and 4) general altruism.

This study tests and analyzes the influence of empowering leadership on employee creativity which is mediated by psychological empowerment. Researchers conduct survey method on state-owned bank employees (ABC Bank) in Pacitan, East Java, Indonesia. Purposive sampling is selected with Likert scale as measurement. The population of this study is 166 respondents, who are permanent employees of the ABC Bank. The data analysis technique used is SPSS 24. The results of this study find that: (1) there is an influence of empowering leadership on psychological empowerment, (2) there is an influence of empowering leadership on individual creativity, (3) there is an influence of psychological empowerment on individual creativity, and (4) the influence of empowering leadership on individual creativity is mediated by psychological empowerment. This study ignores other types of leadership. Further study is needed to examine other types of leadership besides empowering leadership. The level of analysis of this study is individual, so further study could examine empowering leadership conceptualized at the group level because followers will be influenced not only by the dyadic relationship with the leader, but also by the dynamics of the members of the empowered group. This study provides theoretical enrichment from the aspect of empowering leadership, especially at the individual level. Leaders can increase employee creativity by empowering them to do their jobs. Additionally, by creating a work environment that ensures employees feel empowered psychologically.

Purpose - Many researchers analyze VMI as a supply chain collaboration program to reveal its true value. Most of them focus on the dyadic relationship in two stage supply chain systems. This study examines the effect of VMI when it is applied to the different parts of three stage supply chain systems. Research design, data, and methodology - Based on three stage supply chain, this study compares three different systems including full VMI, partial VMI, and non-VMI by using mathematical models. The performances of three systems are compared with the numerical examples of the proposed supply chain models. Results - The numerical examples reveal that full VMI where the manufacturer controls inventories at all stages outperforms any other systems in terms of the system profit and enables all individual members to gain greater profits than non-VMI. Meanwhile, under partial VMI where VMI is implemented between the wholesaler and retailer, only these two members improve their performances and the manufacturer who does not belong to VMI makes less profit than even under non-VMI. This study also examines the impact of market size and profit margin on the system performance. Conclusions - The result of this study supports the common belief that VMI secures the best result when it is applied to the entire supply chain system. The additional findings from the numerical analysis are discussed.

Objective: The purpose of this study was to assess actor and partner effects of mothers' and fathers' parenting stress and family cohesion and flexibility on warm parenting behavior. Methods: The sample consisted of 1,471 couples from the Panel Study of Korean Children. The sample was drawn from the sixth wave of data collection, including mothers and fathers of children aged 60-66 months. Data were analyzed via actor-partner interdependence models. Results: The findings illustrated that the actor effect of parenting stress on warm parenting behavior was significant in mothers and fathers, but there was no partner effect. They also revealed that actor and partner effects were significant in relation to mothers' and father's parenting stress and family cohesion and flexibility. Moreover, there was an actor effect of family cohesion on warm parenting behavior for mothers and fathers, but its partner effect was significant only in mothers. Finally, the mediating effects of family cohesion and flexibility between parenting stress and warm parenting behavior was verified. Conclusion: The results highlight not only the need for dyadic data analysis for mothers and fathers but also the need to consider in depth the fathers' role in parenting. Additional implications are discussed.

This study examined the effects of startup firm's knowledge assets on the effectiveness of their sales strategies, efficiency of sales activities, and management performance, after categorizing these assets into customer knowledge assets and technology knowledge assets. Furthermore, the moderating effects of promotion focus by CEOs and sales managers of startup firms were analyzed. For the analysis, dyadic questionnaire surveys were conducted targeting the CEOs and sales managers of startup firms established at the Gyeongnam Technopark and the KAIST Technology Business Incubation Center in Korea. Hypotheses were verified through structural equation modeling, and moderating effects were identified through ANOVA. CEO's customer knowledge asset strengthened their effectiveness of sales strategies, and sales manager's technology knowledge asset strengthened the efficiency of their sales activities. Also, CEO's effectiveness of sales strategies and sales manager's efficiency of sales activities have been found to enhance startup firm's management performance. Meanwhile, the moderating effect of promotion focus strengthened CEO's effectiveness of sales strategies through CEO's customer knowledge asset and interaction as CEO's promotion focus level increased, but promotion focus of sales managers did not have any significant interaction effect. This study provides implications by offering empirical evidence on startup firms with regard to knowledge assets.

Using a sample of 107 married couples, this study investigated the influence of self-reported argument-communication behaviors on marital satisfaction. The results were as follows. (a) Wives used more criticism, contempt, and self-assertion during marital arguments than husbands. There were no significant gender differences in the levels of defensiveness, stonewalling, and active listening. (b) Multilevel analyses indicated that marital satisfaction was predicted by the person's own level of self-assertion and stonewalling(i.e., actor effects) and by his or her spouse's level of stonewalling(i.e., partner effect). No other significant actor and partner effects were found. Also, there were no significant gender differences in the sizes of effects. (c) A cluster analysis of both spouses' communication behaviors during marital arguments identified four distinct groups of married couples. : mutual constructive, husband constructive-wife destructive, husband destructive-wife constructive, and mutual destructive. Mutual constructive couples reported the best marital satisfaction.
