We study how an advantage given to an interim winner in sequential conflicts characterizes dynamic competition between players and influences their payoffs. As the intensity of competition during each period is negatively correlated, perfect security is not necessarily desirable for contending parties. We present results which are widely applicable to various types of dynamic competition, where competition in each period is linked to the interim winner's relative advantage. Policy implications are also discussed in a variety of areas, and several extensions are explored.

Purpose: The purpose of this study was to find out the role conflict and ways of copying of nurses as underwriters worked at life insurance companies in Korea. Method: The subjects were 141 underwriters who were working at 4 major life insurance companies in Korea. For finding the role conflicts, Role conflict and Ambiguity scale developed by Rizzo, House & Lirtzman(1970) was used, For the ways of coping, Ways of coping scale developed by Lazarus et al. (1984) was used. The statistical method used were mean, percentage, t-test, ANOVA and Turkey test by SAS program. Result: The mean of role conflict was 2.76, and its subcategories were intersender conflict 2.95, sequential order interrole conflict 3.13, interarole conflict 2.69, organizational conflict 2.69, ambiguity from the outcome or responses to one's behavior 2.60, ambiguity from clarity of behavior requirements 2.61. The mean of ways of coping was 2.42 and its subcategories were problem focused 2.42, wishful thinking 2.26, detachment 2.09, seeking social support 2.49, focusing positive 2.72, tension reduction 2.08. There is statistically significant difference between single and married person i.e, single was high than married about role conflict. And also there is statistically significant difference among religion groups i.e., christian was high than none about ways of copying. Conclusion: The results of this study suggest that nurses as underwriters' role conflicts and ways of coping were different that of clinical nurses' and examining medical insurance nurses', Therefore it need more detail repeat studies.

In the practical design, it is important to extract the design space information of a complex system in order to optimize the design because the design contains huge amount of design conflicts in general. In this research FEA (finite element analysis) has been successfully implemented and integrated with a statistical approach such as DOE (design of experiments) based RSM (response surface model) to optimize the thermal deformation of an automotive disk brake. The DOE is used for exploring the engineer's design space and for building the RSM in order to facilitate the effective solution of multi-objective optimization problems. The RSM is utilized as an efficient means to rapidly model the trade-off among many conflicting goals existed in the FEA applications. To reduce the computational burden associated with the FEA, the second-order regression models are generated to derive the objective functions and constraints. In this approach, the multiple objective functions and constraints represented by RSM are solved using the sequential quadratic programming to archive the optimal design of disk brake.

Medical devices separated by a committee of the International Electrotechnical Commission IEC TC (Technical Committee) 62 medical electrical equipment being promoted by the International standards. Actually, a lot of standards were existed, but many national and international standards for medical devices were lacking in practical standards that can be applied to their development. Most international standards were focused in electrical and mechanical safety of medical devices. Therefore, there were few practical standards which contain essential performance evaluation. Although medical device regulations do not enforce a fixed lifecycle model, activities are presented in a sequential manner, thus hinting at a waterfall process. Meanwhile, for a decade or more, software teams have benefitted from agile development methods. Several medical device manufacturers have adopted agile practices while keeping development in compliance with regulations, but conflicts arise and decisions have to be taken in favor of agility or formality. However, if there are new practical standards of medical devices, it must be possible to promote the medical devices industry in their nation. To do this, there is a need to develop a new standard could apply to the international market through the analysis of the medical device related technology. Consequently, new standards such as NP (New proposal) or NWIP (New Work Item Proposal) should be developed through international standardization of medical device technology.

Purpose: The purpose of this research is to develop two medical tourism system models which explain medical tourism phenomenon with a systemic approach. Methodology/Approach: This research was conducted using a qualitative data analysis which mainly refer previous references in relation to medical tourism in the areas of tourism and medicine. Leiper's tourism system model was utilized as a conceptual framework. In-depth interviews with experts in the area were attempted in order to pretest the models. Findings: This research suggests a medical tourism system framework and a medical service provision framework. The first model presents medical tourism components and their relationships within a framework presented in a diagram. The second model shows the relationships among medical services required by medical tourists, the service providers, and service human resources along with movements of medical tourists. Practical Implications: The first model presents a spatial composition of medical tourism components and their relationships, whereas the second model shows the linkage among medical services, the service providers, and relevant service human resources along with time sequential steps of medical tourists. These two models are complementary and may be used as useful tools to observe medical tourism phenomenon with a systemic and holistic approach. These two models may enable stake holders avoid unnecessary confusions and conflicts that result in duplication of government policies and a waste of budget and human resources.

본고에서는 근대로의 지향의식이 넘쳐났던 30년대에 대중적 인기가 높았던 멜로드라마 "사랑에 속고 돈에 울고"를 중심으로 이 작품에 나타난 모더니즘적 특성을 살펴보았다. 30년대 모더니즘과 희곡을 연결지어 고찰한 예는 지금까지 없었다. 당시의 대표적 희곡인 "사랑에 속고 돈에 울고"에 모더니즘 특성이 선명하게 내재되어 있다. "사랑에 속고 돈에 울고" 제목에서 '돈'은 모던한 요소를 드러낸다. '사랑'은 멜로드라마적 요소를 드러낸 것으로 볼 수 있다. 모던한 요소를 드러내는 배경인 근대 문물의 과시는 작품 전반에 퍼져 있고, 홍도는 광호와의 부부관계 뿐만 아니라 시댁과의 인간관계를 완성하는데 실패한다. 물질에 지배당하는 모습을 보여 줌으로써 모더니즘적 현상에 수긍하는 인물이 되었다. 근대 이전의 서사작품에서의 대표적인 갈등구성방식은 수평적이고 순차적이어서 기차역 형태였다고 할 수 있는 반면, 근대 이후의 즉 30년대부터의 서사 갈등구성 방식은 여러 개의 갈등을 동시적으로 형성하여 마치 거미줄 모양이라고 할 수 있다. "사랑에 속고 돈에 울고" 갈등구성이 다축의 다층으로 되어 있고 다양한 사건의 연쇄로 거미줄 모양의 방식을 취해 모더니즘적 형식을 취했다. "사랑에 속고 돈에 울고"에는 가치관의 변화를 주도하는 새로운 내용을 시도하여 도시적이고 서구적인 가치들이 이미 만연한 현실을 바라보는 일반인들의 두려움이 다시 내적 갈등으로 전이되는 요인으로 작용하였다.

본 연구에서는 거시적 넓은 지역에 대한 교통 분석과 부분상세지구(sub-area)의 교통 분석을 서로 단계적으로 연계하며 상호 교통 환경 변화에 대한 영향을 동시적으로 함께 반영하여 방법을 제안했다. 이와 같은 거시적-미시적 연계 분석을 위해 거시적 네트워크 분석, sub-area analysis, 가구통행실태의 출발시각 자료, 부분상세지구의 경계지점에서 시간대별 관측 링크 교통량 자료를 융합 분석함으로써 부분지구에 대한 동적 O/D 교통량을 추정하는 실무적 방법을 제안하였다. 이렇게 추정된 동적 O/D 교통량을 입력 자료로 하여 부분상세지구에 대해 미시 교통류 시뮬레이션 분석을 실행함으로써 다양한 국소적 지구의 교통정책 분석을 가능하게 하였다. 이와 같은 미시적 동적 분석은 거시적 네트워크 분석으로는 파악할 수가 없었던 대기행렬, 교차로 지체, 차량 간 상충 등의 분석을 가능하게 한다. 따라서 교통정책의 효과를 미세한 교통현상 변화까지 분석이 가능하도록 하였다. 또한 본 연구에서는 실제 사례연구를 통해 거시적-미시적 연계 분석에 의한 부분상세지구 미시교통류 시뮬레이션 결과의 현실 설명력에 대한 검증 분석도 수행하여 미시적 동적 분석의 정책 활용 가능성에 대한 참고적 자료를 제공하였다.
