This research aims to cast light upon security characteristics of the Peace Line, which have been underestimated. To understand maritime order and maritime security policy of the Republic of Korea between 1950 and 1970, it is necessary to analyze the Peace Line as line of defence and to investigate its character This research begins with analyzation of historical facts and investigation on security characteristics of the Peace Line. It goes further to examination of legal justification of the Peace Line, which was one of international legal issues of the period, principally regarding its security characteristics. As results of the study, it could be said that the security characteristics of the Peace Line was the line of defensive waters, which set its goal mainly to prevent infiltration of communist spies. The Peace Line had practical effect as it functioned as a base line of the ROK Navy to take anti-spy operation. At the early phase of the Korea-Japan Negotiation, the Korea delegation interpreted significance of the Peace Line passively. After abrogation of Clark Line, the delegation, however, became positive to maintain the Peace Line and its security characteristics. Security characteristics of the Peace Line was recognized again, as it became the base line of special maritime zone which was made in 1972. Through analysis on international law, it is concluded that the Peace Line was fair as a part of the right of self-defense against indirect aggression. North Korea attempted indirect aggression mainly from sea way, and these might undermine peace and cause urgent and unjust damage on the ROK. Thus the ROK's action of anti-spy operation through the Peace Line can be justifiable as considering the right of self-defence. Also the Peace Line accorded with principles of necessity, immediacy and proportionality. As it was argued on the above, the Peace Line as line of defence was one of the most significant factor in the ROK's maritime security history from the Hot war against communist forces to Cold war period after Korean War and must not be underestimated.

Even though, many enterprises began to use management information system, they were not able to attain remarkable outcome. Thus, a purpose for this research is to explore effect that characteristics of information technology and executive support have on its user's confrontation In order to verify this purpose, we selected Nong-hyup's CRM as an object for a proof of effect that characteristics of information technology and executive support have on its user's confrontation. According to this research's conclusion, characteristics of information systems have notable influence on user's confrontation, while executive support did not have significant influence on it. Yet, this research has its limits by considering characteristics of information technology and support from board of directors as only variables among many other possible reasons for user's confrontation. Thus, in the future, there should be another research that considers more various reasons for user's confrontation.

The transient characteristics of separately excited d-c motor driven by thyristor d-c chopper is studied in this paper. The armature controlled system is applied. As a result of theoretrical analysis the following conculsions were drawn: (1) For the transient analysis, it is recognized that the state transition analysis is a more general method and powerful tool than the state equation method or signal flow graph method, although it includes iterative matrix calculations. And the system is dealt with a finite width sampled-data system in the state transition analysis. (2) The transient characteristics of the motor angular velocity and its torque to the sampling duration variation are compared with those due to the amplitude variation of d-c chopper voltage as follows. The attenuation rate of the transient characteristics is equal in both cases, but the initial value of the transient characteristics in former case is greater than in latter case. (3) The roots of characteristics equation of the system lie inside the unit circle of the Z-plane. Therefor the system is stable. Further it is found that as the sampling duration is decreased the relative stability is lessened.

데이터베이스 시스템의 사용자 만족과 품질 관리를 위해서는 사용자 요구사항 및 품질 특성의 정확한 이해와 함께 적절한 품질 측정과 평가가 필수적이다. ISO 25000 시리즈를 기반으로 1차 연구에서 도출된 데이터베이스 시스템 품질 평가 모델에서는 5가지 주품질특성과 이에 따른 21가지 부품질특성, 48개의 내부품질특성의 3단계 계층구조를 제시하였다. 주품질특성, 부품질특성, 내부품질에 대한 우선순위(상대적 가중치) 부여 방법에 대한 연구는 일부 있으나 품질 모형을 데이터베이스 시스템 산업현장에서 직접 사용하는 것은 쉽지 않다. 또한 품질평가를 위한 시간과 비용을 고려할 때 48개 내부품질특성을 모두 평가한다는 것은 현실적으로 거의 불가능하며 데이터베이스 시스템에서 요구되는 무결성 수준에 따라 품질평가의 수준도 다르다. 본 연구에서는 다목표의사결정기법의 하나인 AHP(Analytical Hierarchy Process)기법을 이용하여 데이터베이스 시스템 품질특성을 가중치에 따라 선정하는 방법을 제시하고 이를 통해 품질모형의 현실적인 적용 가능성을 제공할 수 있다.

Purpose: The purpose of this study is to clarify the role of decoupling between job characteristics, innovation behavior, and innovation resistance in order to seek ways for companies to survive and grow continuously through innovation activities in various uncertain situations. Research design, data and methodology: A total of 263 valid questionnaires were collected and used for analysis for employees working at the company. For the analysis, simple and multiple regression analysis, and 3-step mediated regression analysis were conducted using SPSS 24.0 and AMOS 24.0. Results: First, it was found that skill variety, task identity, autonomy, and feedback increase decoupling, and decoupling increases innovation resistance. In addition, it was confirmed that decoupling had a mediating effect between job characteristics and innovation resistance excluding task significance. Finally, it was found that task significance and feedback increase innovation behavior, and decoupling and task identity increase innovation resistance, but feedback can alleviate innovation resistance. Conclusions: As a result of the analysis, the fact that job characteristics excluding task importance have a positive effect on decoupling means that there are two sides of job characteristics perceived by employees. In other words, it means that the results of analysis on the jobs that the company assigns to its members may not be effective. In addition, decoupling, a phenomenon that seems to be accepting on the outside, but perceives that it is negative on the inside, means that there is a possibility to reject innovation. Therefore, prior to carrying out innovation activities, companies should give clear job specifications and meanings for the job and give them autonomy when assigning jobs to their members. In order to provide appropriate feedback, the company must design, operate, and provide feedback. It was found that there was a need to review the overall effectiveness. In addition, efforts such as strengthening corporate-level fairness, maintaining psychological contracts, and realizing authentic leadership should be preceded to reduce decoupling.

The purpose of this study is to investigate the causal relationship between job characteristics and creativity. The role of transformational leadership is also examined. To identify the relationship between core team job characteristics and transformational leadership, an empirical survey was conducted through surveys of domestic distribution companies. Among the collected questionnaires, missing and insincere responses were excluded and 636 individuals of 107 teams were used for the SPSS 18 analysis. It was found that job meaningfulness was positively related to team creativity and transformational leadership also had a significant effect. Task feedback was shown to be an important factor on the motivation to perform tasks successfully. In the case of transformational leadership, this leadership style helped individuals overcome fear by providing support, sympathy, and consideration to create novel ideas. But, its effects were different on team creativity when it interacted with core job characteristics. Departments where creativity is highly emphasized within an organization are able to design job characteristics which fit the task at hand. Moreover, transformational leadership brings about different effects on team creativity when it interacts with job characteristics. The findings of this study suggest that organizations should consider characteristics of tasks and individuals as well when conducting education and training.
