A detection filter assigns a specific direction to the response with respect to each fault, by which it can detect the occurrence of the several faults. The separability of a detection filter can be determined by the orthogonality among these directions. In this paper, we define the separability of a detection filter as the orthogonality of the directions in output space, and present it mathematically by using conditions number. An algorithm to determine the optimal sensor gain to maximize separability is proposed and applied to the PWR nuclear reactor model.

The purposes of this study are as follows. First, it is to review the features of discount stores that are expected to grow rapidly and continuously due to their low price, low cost, bulk purchase, and multiple shops, and to pinpoint problems arising from the establishment and position of the stores. Second, it is to analyze relevant issues in regard to the present status of fashion good distribution in discount stores by studying the situation, structure and problems of domestic fashion distribution along with the present status of the distribution in discount stores, and to suggest directions for the development of fashion distribution and discount stores. A positive study was carried out on the buyers of big domestic discount stores through one-to-one interviews focusing on the distribution of fashion products within Seoul and the Metropolitan area. The following is the directions for the development of clothing distribution and discount stores ; 1. The relative importance of fashion goods in a discount store will be increased with the tendency of fashionable and differentiated shops ; 2. The GMS or category killers will be established from around 2003 when the market is expected to become saturated with a great deal of discount stores. 4. Discount stores will change and reform without being restricted to a certain existing industry or business condition, and distribution channels will diversify over the border. The demand and supply system will be balanced based on a global marketing which will be adjusted on the international level.

The study aims to explore the policy directions for young farmers within Korean agricultural context, particularly in Chung-nam Province. In order to accomplish this, young farmers were classified into three categories: successors, new farmers, potential farmers. The importance of young farmers is becoming more of a focus due to decline of population numbers in rural communities as well as the aging of agriculture population. In order to address these two problems, it is necessary to create and implement policy to support each category of young farmer. Rather than the current focus on nurturing young farmers as a labor force, the role of young farmers in maintaining local communities should be expanded in current agricultural system. The local community should provide appropriate conditions for young farmers in Chung-nam Province for the various purposes they have and the roles they fill. In conclusion, it is necessary to provide a 'space' where young farmers can meet base on the community. For this, the role of the community based intermediate support organization for the integrated support system is of great significance.

This paper describes the design, simulation, development, and experiment of a six degree-of-freedom micropositioning parallel manipulator. A movable stage was supported with six links, each of which extends with a dc-servo micropositioning actuator. In case of parallel manipulator, while the solution of the inverse kinematics is easily found by the vectors of the links which are composed of the joint coordinates in base and platform, but forward kinematic is not easily solved because of the nonlinearity and complexity of the parallel manipulator's kinematic output equation with the multi-solutions. The movable range of the prototype was ${\pm}25mm$ in the x- and y-directions and ${\pm}12.5mm$ in the z-direction. The minimum incremental motion of the prototype was $1{\mu}m$ in the x- and y-directions and $0.5{\mu}m$ in the z-direction. The repeatability of the prototype was ${\pm}2{\mu}m$ in the x- and y-directions and ${\pm}1{\mu}m$ in the z-direction. The motion performance was also evaluated by not only the computer simulation of CAD model but also the experiment using a capacitive sensor system.

The port space can be considered to be the space in which the characteristics of the port city are best expressed. Also, since it acts as a representative gateway along with the airport, it can have a direct impact on the image of the region and country. However, the harbor hinterland has been a refuge during the war in the past, and it has been concentrating on development related to the port industry; hence, it has a poorer residential environment. Therefore, in this study, in order to ensure equal development in space and equal access to basic urban services, urban design directions were suggested for the harbor hinterland based on the concept of an inclusive city'. To this end, through factor analysis, urban planning elements that can be applied to urban design were derived, and through PLS(Partial Least Square)regression analysis, based on the opinions of residents and experts, urban design directions for the port hinterland were presented. The study site was Gamcheon Port, one of the Busan Ports in Korea, the hinterland of Gamcheon Port was a high slope, and the residential environment was relatively poor due to the dense concentration of older residential areas.

This paper is intended to review the major problems of rural settlement development and attempts to find the direction to enhance the effectiveness of rural settlement development policies and strategies. Small amount of financial resources being mobilized, similar policies for rural settlement development have been implemented sectionally by the respective sectoral goverment bodies. It has resulted in a lot of coulict and ineffectiveness in the process of rural settlement development To rationalize the rural settlement development, there should be some change in the current practice of the project: integration of development efforts, consideration of regional situation and settlement system, and introduction of principles and criteria suitable for rural settlement planning.

Tourism is often considered as one of the main industries to promote development and modernization in small South Pacific islands countries. In Fiji, this was recognized in the 1960s, and resulted in large-scale resort based tourism development in coastal areas. While tourism has obvious advantages to the economy, a lot of problems such as exclusive foreign control of the main hotels and resorts, considerable overseas leakage of earnings, the limited participation by indigenous resource owners, and localized environmental damages to reefs and mangroves are emerging. For sustainable tourism development, it is needed to set growth objectives and targets for tourism in terms of benefits to Fiji, and to concentrate support on 'Rural Tourism' such as community-based tourism that have lower leakage and put more into local economies. Through case study in this paper, to develop rural tourism at the local level, several recommendations are as follows: 1) to introduce various rural tourism programs such as experiencing Fiji's traditional culture, participating in activities, picking fruits and harvesting agro-products, 2) to enhance aggressive promotion and marketing strategies, 3) to build the capacity of local communities for improving the quality of tourism services, and 4) to provide the infrastructure for tourism business such as road accessing, water supply and disaster prevention.

This paper begins by reviewing research on female entrepreneurship. In this research, authors proposed the methodological tools based on systematic approach using economic and statistic methods and 5Ms concept. Analysis algorithm consists of four stages: evaluation of women entrepreneurship scale and business directions, analysis of employment in women's enterprises and business environment in Kazakhstan. The main limitation of this study was the lack of some gender-related indicators on the development of entrepreneurship. Further, the obtained results showed strong and weak points of female entrepreneurship in Kazakhstan. According to the results, there has observed increase in contribution of women in social-economic development of the republic, women's entrepreneurial activity is increasing, and the number of enterprises headed by them is growing. However, the growth of female entrepreneurship occurs while maintaining their insignificance in terms of turnover and number of employees. There is a pronounced industry specificity of female entrepreneurship: the service sector. In accordance with this, there were identified priority areas and there were developed recommendations for the development of female entrepreneurship in Kazakhstan.
