Uncertainties are unavoidable in engineering applications. In this paper we propose an alpha reliable multi-variable network design problem under demand uncertainty. In order to decide the optimal capacity enhancement, three performance measures based on 3E(Efficiency, Equity, and Environmental) are considered. The objective is to minimize the total budget required to satisfy alpha reliability constraint of total travel time, equity ratio, and total emission, while considering the route choice behavior of network users. The problem is formulated as the chance-constrained model for application of alpha confidence level and solved as a lexicographic optimization problem to consider the multi-variable. A simulation-based genetic algorithm procedure is developed to solve this complex network design problem(NDP). A simple numerical example ispresented to illustrate the features of the proposed NDP model.

The classification of biotope type in major Korean cities was made based on the land use concept rather than the ecological concept of the land as the habitat of biological communities. Therefore, biotope type need to be reclassified according to ecological concerns and regional characteristics. This study attempts to clearly define various critical concepts regarding the classification of biotope type, such as classification hierarchy, classification criteria, classification factor, classification indicator, classification key, and classification standard. Furthermore, it also attempts to suggest the ways to improve the classification system of biotope type by sampling the cases of major Korean cities. The classification system of biotope type is required to have a coherent system that provides basic guidelines, standards and hierarchy with regard to biotic, abiotic and anthropotic factors, as well as classification indicators and classification keys.

본 연구에서는, 기존의 악세스빌리티지표가 다양한 효과를 고려하지 못한다는 점에 착안하여, 새로운 악세스빌리티지표를 개발하였다. 노드의 중심성을 나타내는 중심도함수에 근거해, 네트워크 악세스빌리티지표(Netword Accessibility Index)와 철도이용자의 효용최적화의 관점으로부터 유틸리티 악세스빌리지표(Utility Accessibility Index)를 제안하였다. 그리고, 본 연구에서 제안한 지표가 종래의 지표보다 철도건설에 따른 편익치를 보다 정확하게 나타내는지를, 서울시지하철5호선과 오사카JR동서선의 개업효과를 계측함으로써 검증하였다. JR동서선의 경우, 중심지까지의 기존노선이 기설되어 있어 소요시간 단축효과보다 수송력증강과 철도네트워크의 확충에 의한 효과가 보다 크게 반영되었다. 또한, 위에서 산출한 편익치를 환수하기위한 기초데이타로 활용해, 고정자산세와 토지양도 소득세를 적용해 환원액을 산출하였다. 그리고, 이렇게 구한 환원액을 특정재원화시켜, 지하철5호선과 JR동서선의 사업주체에 보조해, 사업자의 채산성에 어떠한 영향을 미치는지, 신선건설비를 부담하는 해당 지자체의 비용부담을 어느정도 경감시킬 수 있는지를 정량적으로 밝혔다.

In this study, questionnaires and field interviews in practice the use of PMS, in assessing companies' usage and employee's perceived importance of performance measures for the characteristics of PMS was investigated. The results of this study can be summarized as follows: First, the companies in the respective business environment and strategies to improve the performance measures reflect, but was using a lot of financial measures. Second, discrepancy-between employee's perceived importance and companies' usage of non-financial measures was showed. Thus, there is a need to develop a variety of performance measures and increase the use of non-financial measures. Third, the company has to consider design and use of PMS to induce the awareness of employees and behavioral changes in order to improve organizational performance.

기술력평가는 기술사업화 주체가 기술을 사용하여 수익을 창출할 수 있는 능력을 평가하기 위한 것으로, 국내 기술성 평가기관들이 각자 독자적인 평가 모형을 활용하여 평가를 수행해오고 있다. 특히 최근에 개발된 해양 및 수산 산업 분야의 기술력 평가모형은 타 산업 대비 열악한 기술개발 환경과 연구개발 성과를 대상으로 평가를 수행해오면서 기존의 평가체계 내에서는 많은 평가대상 기술들이 부적합 판정을 받아오고 있었다. 이러한 것은 기존 평가체계가 타 산업에서 활용되고 있는 공통적인 평가지표와 평가척도를 유사 또는 동일하게 사용하면서 발생되는 문제점으로 인식되었고, 또한 해양 및 수산 산업의 특수성이 반영되지 않은 평가체계에서 비롯된 것으로 파악되고 있다. 따라서 본 연구를 통해 기존 평가체계를 해양수산 산업의 특수성을 반영할 수 있는 평가체계로 개선하여 해당 산업에 특화될 수 있는 평가체계를 새롭게 제안하고자 하며, 이를 위해서 기존 평가지표의 개선, 시뮬레이션 기반의 평가척도의 재설정 방법과 평가등급 산출방법에 대한 새로운 제안을 하고자 한다. 마지막으로 개선된 기술력평가 체계를 활용하여 시범사례평가를 수행하여 기존 평가체계를 통한 평가결과의 Gap분석을 수행하고자 한다.

The social impact of science and technology is increasing, the meaning of technology assessment is not small in modern society, Specially, the technology assesment(TA) has been institutionalized and performed by Korean administration and its official results has reflected directly in the S&T policy. Therefore, the technology assesment is a device that prepare the negative effects of S&T and the social controversy in advance. To select the target technology of technology assessment will be done carefully in various perspective and concerned with the characteristics of technology assessment emphasizing social assessment, the institutional system of selecting one technology in each year and the contents and methods of evaluation that are determined in accordance with technology characteristics. However, the method of selecting target technology in TA is mostly peformed by qualitative discussion and vote rather than by reflecting various opinion and understanding TA until now. In this paper, we developed the indicator has to be considered to select target technology for TA by using factor analysis. Developed indicator is consist of five factor, such as the need for social consensus and the size of social/cultural impact etc., and we weight each factor by using Analytic Hierarchy Process(AHP). Futhermore, we show the example how to applicate directly these indicator and weights to select target technology and suggest institutional application in TA. Though using developed indicator in this paper, we expect to select appropriate technology for institutional TA and the application of TA results in society and public policy can be strengthened.

Korea's self-support program has constituted one of the most important workfare policy for the past 25 years. However, many pointed out the lack of field perceptions in the performance indicators of self-support program, such as overemphasis on the economic performance and uniform application regardless of regional types. This research intends to derive policy implications to improve performance indicators of self-support program by analyzing field perceptions, utilizing ISA(Importance-Satisfaction Analysis) method. Analysis on the difference between importance and satisfaction shows that the procedure was perceived more important than the consequences. It also reveals that current indicators were not satisfactory enough to reflect field practices. Finally, ISA matrix classified indicators into keep, improve, policy reconsideration area, and obvious differences were found by regional type. These findings suggest the importance of field-orientation in performance indicators, and by which, can serve as an exploratory study for the improvement of performance indicators.

The purpose of this study is to analyze the actual operation status of the financial performance target management system which is currently operated and to provide improvement plan based on this analysis. For this purpose, I examined the performance management system and performance indicators of the Ministry of Justice, which is one of the criminal justice administration agencies. Although the overall appropriateness of the current performance management system is considered to be somewhat appropriate as a whole, there is a negative perception about the performance measurement method for measuring the achievement of the performance target, and the evaluation of the performance of the performance target is relatively low. In addition, there were many criticisms about the establishment and measurement of the Ministry of Justice's overall performance indicators, such as the tendency to select indicators that are easy to achieve and easy to measure. In order to remedy these problems, it was highly suggested that the importance of indicators should be more emphasized and expanded so as to set up high-performance indicators. Based on the results of this analysis, some suggestions for policy implications and some alternatives for improvement of financial performance target management system were suggested.
