An electro-optical camera system consists of many subsystems such as the optics, the detector, and the electronics and so on. They may create variations in the processed image that were not present original scene. The performance analysis of the electro-optical camera system is a mathematical construct that provides an optimum design through appropriate trade off analysis. The SNR(Signal to Noise Ratio) is one of the most important performance for the electro-optical camera system. The SNR analysis shown in this paper is performed based on the practical high resolution satellite camera design. For the purpose of the practical camera design, the analysis assumes that the defined radiance, which is calculated for the Korean peninsula, reached directly to the telescope entrance. In addition, the actual operation concept such as integration time and the normal operation altitude is assumed. This paper compares the SNR analysis results according to the various camera characteristics such as the optics, the detector, and the camera electronics. In detail, the optical characteristics can be split into the focal length, F#, transmittance, and so on. And the system responsivity, the quantum efficiency, the TDI stages, the quantization noise and the analogue noise can be used for the detector and the camera electronics characteristics. Finally this paper suggests the optimum design to apply the practical electro-optical system.

This research is to establish a theme-type organic edu-farm model and provide ways to practically apply it so as to vitalize urban-rural exchange through the emerging concept of green tourism. This research also traces the practical development of organic edu-farm programs. Organic edu-farm(OEF) should be some of the ideas to develop organic agriculture resources according to the local features, and learn by direct and actual experience a life of organic farm. A few policy suggestions to put OEF model in practical use are proposed. What the state needs to do through direct involvement are to put efforts at demand expansion on organic farm products, to clean and beautify the green rural environmental settings, to build more urban-rural exchange facilities. What is more important, however, is financial support, to create the network and to develop program contents for each OEF operation unit. The OEF model proposed in this research will be applied as a relevant reference in planning and realizing sustainable green tourism at the village level.

GongJu is a historical city. There has been scattered Baekje, Chosun and modern cultural heritages in GongJu. Cultural heritages in Baekje is simply preserved in their current condition. Chosun and modern cultural heritages have left their traces only, so that faded from the memory of the world. We must not lose the historical interconnectedness that is created by these heritages. This study is to analyze the architectural culture contents and its practical use program in urban side, and search for the strategy. The purpose of this study is as follows: The first is to retrieve the scattered heritages according to the age and area(as a spot). The second is to improve the street landscape through the linear linkage connecting from spot to spot.(as a line) The last is to create the image of historical city through the regional development.(as an area)

The purposes of this study were (1) to segment the men in twenties and thirties according to apparel shopping orientation and (2) to create a profile for each group with regard to importance of store attributes, self-image and demographic variables. The questionnaire was administered to men in twenties and thirties living in Seoul and data were analyzed by frequency, percentage, factor analysis, cluster analysis, χ²-test, and one-way ANOVA. The results were as follows : 1) By cluster analysis of apparel shopping orientation factors, three groups were identified : (1) ostentatious shopper(44.5%), (2) practical shopper(21.8%), and (3) individuality-pursuit shopper(33.7%). 2) Three groups were compared on store attributes and self-image. Significant differences were found among the three groups on two variables. Ostentatious shoppers pursued the masculine and sophisticated image and tended to prefer the store image and reputation, convenient transportation and parking place, and variety of products. Practical shoppers pursued the self-image which reflected the conservative and not-noticeable image and considered the moderate price of the products most importantly. Finally, individuality-pursuit shoppers preferred the sexy and noticeable image and considered the display and accommodation of the trendy products. 3) In terms of the demographic variables the significant differences were found on education, occupation, monthly income, and marital status. In general ostentatious shoppers tended to earn higher monthly income than those of the two groups. Practical shoppers tended to be well-educated and individuality-pursuit shoppers tended not to be married.

This study was conducted to effectively develop rural tourism in Korea. For the purpose, tourism that can develop with local industries and cultures together was designated as life-type tourism and development models of such tourism were reviewed based on an understanding that province-oriented tourism is necessary. An analysis of three actual cases of Japan led to following results. First, life-type tourist destinations can be developed in connection with making local areas based on their special themes, can be developed in relation to their life cultures based on their peculiar life cultures and can be developed in creative forms using characteristic environment and organizational culture of those areas. In pursuing life-type tourist attractions, it will be possible to make practical development using it with those three basic models. Second, it is important to form a flow covering the entire regions based on their own special themes, to build cyclical structure of regions and tourism and tourism and industries and to create overall conditions that can help local residents get benefits and join together, in order to develop such life-type tourist destinations. Development of life-type resort tourist destinations needs roles of practical organizations that can effectively manage them, but such organizations should be dynamic and should be distant from management of money as much as possible.
