This study analyzed the effect of Servant Leadership on leader trust and job engagement for the lower-level leader in airline crew occupations with the aim of identifying the possibility of establishing the theoretical framework of Servant Leadership in the service industry. As a result of the regression analysis, it was found that the social learning dimension of Servant Leadership has greater influence than the social exchange dimension on the leader trust, while the influence on job engagement is the opposite. The results of this analysis can be interpreted that trying to learn the words and actions of the Servant Leader is more effective in further consolidating the trust of the subordinates in the leader. On the other hand, the Servant Leader's words and actions for social exchange are inferred to have more influence on the job engagement. This study is targeted at air transport services, exposing limitations to the generalization of research results. Throughout leadership research and organizational research, including Servant leadership, further studies applying the social learning theory and social exchange theory presented in this paper are expected to produce theoretical results that will lead to the emergence of a new framework for research analysis.

This study suggested a knowledge theory, theoretical framework and general principles in methodologies for library and information science by theoretically weighing domain analysis. The central concept to domain analysis are a subject knowledge constituting the domain and a discourse communities to share their knowledge. Therefore the study described a definition of domain and explained domain in ontological, epistemological, and sociological dimensions, proposed eleven approaches available in domain analysis. And the study argued the implications of domain analysis for library and information in position of socio-cognitive view and pragmatic realism.

There is a high demand for the diagnostic medical blood analyzer in the global medical device market. The domestic market is in infant stage, but expected to grow very fast. In this study, we attempt to provide several ways for production improvement in order to secure price competitiveness of domestic medical blood analyzer. For this purpose we identify the problems of current production process using ARENA simulation and suggest several alternatives for productivity improvement.. Five steps of TOC (Theory of Constraints) and ARENA simulation are employed to predict productivity of each alternative and to suggest further improvement.

본 연구는 가족의 구매의사결정에 대한 실증조사로서 성별역할관념론 및 자원이론과 가족구성원의 지각된 영향 간의 관계를 규명하였다. 영향을 주는 구성원은 남편과 아내와 자녀로 한정했으며, 영향을 지각하는 가족구성원은 남편과 아내로 제한하였다. 성별역할관념변수는 Scanzoni Sex-Role Scale(SSRS)로 측정하였으며, 자원변수는 남편과 아내 각자의 수입과 교육수준으로 측정하였다. SSRS 는 요인분석을 사용하여 차원(요인)을 파악한 후 자원변수와 함께 지각된 영향 간의 관계를 규명하기 위하여 다변량 회귀분석을 사용하였다. 요인분석 결과는 Scanzoni(1975)의 분석 결과와 요인구조 면에서 차이가 있었다. SSRS 는 아내의 척도 2 개 차원과 남편의 척도 3 개 차원으로 구성되어 있다. 그러나 본 연구에서 남편의 척도는 1 개의 차원으로 나타났다. 조사대상이 된 제품은 TV, 냉장고, 세탁기, 침대, 장롱, 식탁, 자동차, 남성정장, 여성정장, 여행지로 모두 10 개 였다. 성별역할관념변수의 영향을 분석한 결과는 "제품 특이적"이거나, 영향을 지각하는 "지각주체 특이적"이거나, 성별역할관념의 "차원 특이적" 현상을 보였다. 또한 우리나라의 남편들은 성별역할관념변수에 상관없이 자기의 영향을 더욱더 크게 지각하는 반면, 아내의 영향을 더욱더 적게 지각하는 경향이 있었다. 아내들도 남편보다는 자기의 영향을 더욱더 크게 지각하는 경향이 있으나 남편만큼 강한 것은 아니었다. 이 결과를 분석하면 남편들은 남성우월의 전통을 유지하려는 경향이 높은 반면 아내들은 이런 전통에 변화를 기대하는 진보적 성향을 띠고 있는 것으로 해석된다. 본 연구의 결과 자원이론은 지지를 받지 못하는 것으로 나타났다. 다시 말해 자원이론은 부부사이에서 기대했던 영향과 반대 방향으로 나타났을 뿐만 아니라 부모와 자식 간에도 기대했던 것과 반대 방향으로 나타났다.

This study aims to explore patterns and characteristics of coordination between evidence and theories which were found in pre-service elementary teachers' writing for their science inquiry. Five science inquiry activities and a total of 115 writings of the participant teacher at the elementary teacher preparation university in Korea were collected and analyzed for this study. Based on the writing analyses there were found four types of coordination between the evidence and theory. We proposed four types as: Type 1-Consistency of evidence and theory; Type 2-Consistence of evidence and theory including more extension or elaboration of theory; Type 3-Inconsistence of evidence and theory Type 4-Inconsistence of evidence and theory followed by coordination of them. Firstly the findings indicated that the most to least frequent types were Type 1, Type 3, Type 2, and Type 4. The most frequent type was Type 1. It is interpreted that theory in the inquiry questions were frequently figured out by participants and they selected supporting evidence out of data found. There were rarely found relations between activity topics and frequencies of coordination types except in activity 1. The findings in this study will connect to the point of how students collaborate their previously owned knowledge with experiment planning, data analysis and interpretation and making of their own scientific claims.

Self-theories regarding general intelligence and English ability were measured from two countries (Korea and Pakistan) and their relationships with self-reported overall academic achievement and English language achievement were examined. No significant mean differences between the two countries were found regarding college students' self-theories. There were significant mean differences in overall academic achievement and English achievement between the two countries. Both the overall academic achievement and English achievement were significantly correlated with various self-theories while taking both samples together. Achievement measures were predicted by self-theories of general intelligence and English language ability. The current study highlighted the relationship between self-theories about general intelligence and English language ability and their relationship with self-reported achievement in two cultural contexts. This research also introduced new instruments to measure self-theories that can be used in studying self-theories in different domains.

The present research integrated various theoretical perspectives of human unlawful behaviors in order to clarify the psychological mechanisms that underly the changes in compliance with and attitude toward law as time goes. Most well-known theories such as classical theory of crime, biosocial and evoluationary theories, and psychological perspectives including psycho-dynamic theory, personality, intellectual/moral development theories, and decision-making were discussed in their unique points in explaining human unlawful behaviors. Finally, social-learning theory and cognitive-dissonance theory has been suggested to explain the psychological mechanism of the phenomena in which people's attitude toward law and compliance with law become weaken through violation experiences of trivial lawful regulations. Especially, the logic of cognitive-dissonance theory (that people committed violation of trivial laws should experience dissonance with their original belief of compliance with law and negative arousal and try to remove the arousal by change their belief along with their behavior) were theoretically convincing to explain the phenomenon and supported by a series of experimental studies. Several practical implications for future constitutional and political activities were discussed in the basis of the cognitive dissonance theory.

The purpose of this paper is to introduce time-series causality analysis by combining time-series technique with graph theory. Vector autoregressive (VAR) models can provide reasonable interpretation only when the contemporaneous variables stand in a well-defined causal order. We show that how graph theory can be applied to search for the causal structure In VAR analysis. Using Maryland crop cash prices and CBOT futures price data, we estimate a VAR model with directed acyclic graph analysis. This expands our understanding the degree of interconnectivity between the employed time-series variables.

In this paper, we propose a NPC decision making model based on Prospect Theory which tries to model real-life choice, rather than optimal decision. For this purpose, we analyse the problems of reference point setting, diminishing sensitivity and loss aversion which are known as limitations of the utility theory and then apply these characteristics into the decision making in game. Dynamic Terrain Analysis is utilized to evaluate the proposed model and experimental result shows the method have effects on inducing diverse personality and emergent behavior on NPC.
