In this paper, we have surveyed the existing architectures of the image processing systems for several meteorological satellites and identified issues which are taken into consideration to construct the advanced meteorological satellite image processing system that is being developed by NMSC(National Meteorological Satellite Center). Most of the existing systems provide the functionalities of the image acquisition, the image processing, the data management, and the data dissemination. Those systems have some common problems with respect to system integration and system maintenance. To solve these problems, NOAA, NWS and ESA suggest new system architectures to improve the existing systems. This paper introduces domestic and foreign approaches to build the satellite image processing systems and studies some issues and strategies for developing those systems.

Jeong-Gak is one of the Confucian architecture in Cho-Sun Dynasty. This study is founded on the architectural characteristics and the Confucian order of Jeong-Gak. The Cho-Sun Dynasty had put in operation positive Jeong-Pyo Policy for diffusion Confusion ethics and educate the people. Prize methods of Jeong-Pyo Policy are Jeong-Ryeo, Jeong-moon, remit corvee, present a post and present goods. Jeong-Moon and Jeong-Ryeo is red gate. Vocabularies of Jeong-Moon and Jeong-Ryeo have used mixing but I think that both meaning is different essentially each other. The red gate that elected in front of gate or gateway is Jeong-Moon and another red gate that elected an entrance a village is Jeong-Ryeo. Jeong-Moon and Jeong-Ryeo have no roof, so they are many problem for maintenance and management. Accordingly Jeong-Gak come out from the reign of King Jung-Jong because shelter of Jeong-Moon and Jeong-Ryeo. The function of the Jeong-Gak is shelter of the Jeong-Moon and Jeong-Ryeo, encouragement of Sam-Gang(三綱) ethics, and ostentation of a family. Besides it has a monumental characteristic. It has been distributed the whole country land that Jeong-Gak is closely related with the community of same family (rural community) the latter period of the Cho-Sun Dynasty. The architectural particularity of the Jeong-Gak is brilliance of building materials as compared with different Confucian architecture and appearance of various architectural type. It is that a type of Jeong-Gak appeared Jeong-Ryeo-Gak type, a lofty gate type, and Stone Jeong-Ryeo type. And there are keeping a rule that is to say Confucian order clearly.

The purpose of this study was to found that the important design reform points for improvement of the public open space quality. For this purpose, surveyed the users of the public open space and the experts working for the public open space planning for the design elements of the public open spaces in terms of importance and satisfaction. The scope of the study was limited to Mapo-gu, Seoul and the buildings constructed since 1992 were sampled. the data collected were subject to Importance-Performance Analysis. As a result, 'waste boxes, vending machines and other amenities', 'characteristic floor and pedestrian environment', 'designs and their layout in harmony with the surrounding and landscape facilities', 'facilities checking and patrol for safety' and 'entire area of the public open space'. Based on the above findings, the following reform measures are put forwards for improvement of the public open space quality; First, the public open spaces should be equipped with sufficient amenities. Second, it is necessary to check the facilities regularly, while enhancing the safety through patrols. Third, it is essential to reflect user's needs in public open space planning, while applying the important design elements to the public facilities. Fourth, in order to create a comfortable pedestrian environment within the public open space, it is deemed necessary to divide the space into the passages for passers-by and the recesses for uses. Fifth, it is necessary to amend the Building Code to the effects that the radio of the landscaped area to the entire area can be readjusted together with the night lighting facilities. Sixth, it is desirable to give the weights to the important design elements for the public open spaces, so that the quality public open spaces can benefit from the incentives. In addition, regular maintenance and management should be ensured by policies.

Purpose: Apartment housing should conduct a cyclic repair to keep and maintain the building performance since they are constructed. Therefore, the repair plan would be provided for long term period which explains the repair time, items and repair cost. Residents of apartment housing are responsible to pay for the repair activities. For repair cost, residents would reserve the money for repair little by little continuously until the required repair time because the repair cost takes a big burden for residents and lots of money a time. But, there is no systematic approach to provide the long term repair cost because it is no proper forecast of the repair cost to the upcoming repair time. In this study, it aimed at providing the monthly accumulation of the long term repair cost with the survey data in Seoul. Method: For these, the surveyed data are classified into 6 categories and number of data are 1,918. In addition, it developed the repair cost model for the 24 repair works and the cumulation function which is reflected with the each cost model. Result: This study are shown as follows : First, among the various estimation for the repair cost, the power function has a goodness of fit in statistics. Second, the monthly accumulation would be 12,840 won/household in size of $100,000m^2$ management area and $81.7won/m^2$ in size of the 1,000 household number during 40 years.

There have distinctly been no the installation criteria and maintenance management of BIPV systems, although the BIPV market is consistently going on increasing. In addition, consideration of the BIPV generation quantity which has been installed at several diverse places is currently almost behind within region in Korea. Therefore, the main aim of this study is to evaluate the BIPV generation and to be base data of reducing rate depending on regional installation angles using PVpro which was verified by measured data. Various conditions were an angle of inclination and azimuth under six major cities: Seoul, Daejeon, Daegu, Busan, Gwangju, Jeju-si for the BIPV system generation analysis. As the results, Seoul showed the lowest BIPV generation: 1,054kWh/kWp.year, and Jeju-si have 5percent more generation: 1,108.0kWh/kWp.year than Seoul on horizontal plane. Gwangju and Daejeon turned out to have similar generation of result, and Busan showed the highest generation: 1,193.5kWh/kWp.year, which was increased by over 13percent from Seoul on horizontal plane. Another result, decreasing rate of BIPV generation depending on regional included angle indicate that the best position was located on azimuth: $0^{\circ}$(The south side) following the horizontal position(an angle of inclination: $30^{\circ}$). And the direction on a south vertical position(azimuth: $0^{\circ}$, an angle of inclination: $90^{\circ}$) then turned out reducing rate about 40percent compared with the best one. Therefore, these results would be used to identify the installation angle of the BIPV module as an appropriate position.

Objectives: This study attempted to apply the Intervention mapping and Transtheoretical models to develop a program to promote moderate alcohol drinking in university students. Methods: Surveyed data from 1,137 university students were analyzed to identify personal and environmental determinants for alcohol drinking. Based on these determinants, program objectives were established. Crossing the objectives with related important determinants resulted in matrices of learning objectives for which educational strategies were developed. Subsequently, an intervention program were designed to achieve those objectives. Results: Identified personal determinants included awareness, attitudes, self-efficacy and behavioral skills. Environmental determinants were binge drinking behaviors of family members and peers, and social pressure for drinking. Program, impact and learning objectives were developed to change the identified determinants. Program activities included provision of information on positive and negative consequences of binge drinking, opportunities for assessing one's drinking pattern, increasing outcome expectancies of and skill building for monitoring drinking, resisting peer pressure and managing stress. To facilitate adoption and maintenance of the program, an intervention diffusion plan was suggested. An evaluation plan was developed by utilizing RE-AIM framework. Conclusions: In order to expand evidence bases for effective theory-based programs, the developed program should be tested in diverse university settings.

This paper proposes the development model of the aerodrome traffic control simulator (ATCS) System for the domestic airport. The application of the ATCS is used as a OJT training function for the air traffic controller and research function for a new control procedure. In order to perform those functions, we classified the ATCS in three types such as education, research and integrated management system, and the ATCS types analysed by the working and OJT training condition in domestic airport. Therefore, we proposed the ATCS models such as uniform type, differential type, and center type, and analysed the merits and demerits of the proposed models. Also we looked up ATCS's application in terms of the building and maintenance costs, operational utilization and scalability. So, we proposed the differential type which was suitable for the developing ATCS for the domestic airports.

With increasing astronomically damage costs caused by frequent and large-sized flood, a hazard map containing comprehensive analysis results such as inundation trace investigation, flood possibility analysis, and evacuation plan establishment for flooded regions is a fundamental measure of non-structural flood prevention. Though an inundation trace map containing flood investigation results occurred by typhoon, rainfall and tsunami is a basic hazard map having close relationship with a flood possibility map as well as a hazard information map, it is often impossible to be produced because of financial deficiency, time delay of investigation, and the lack of maintenance for flood traces. Therefore, this study proposes the accuracy enhancement procedure of inundation trace map with flood damage information and three-dimensional Digital Elevation Model (DEM) for the past frequent flooded regions according to a guideline for inundation trace map of National Emergency Management Agency (NEMA).

A practical use of the location information and user requirement are increased in a mobile environment which supports the portability. And Various service which GIS is related with a Spatial DB have been processed. Generally, logical relation of a traffic network which organizes the Road DB uses a basic node-link structure. In this way, Designed structure can not be flexible at various model apply and are not efficient with a database retrieval in a maintenance management side. In this research, We supplement with the problem of a existing network model and the limitation of the building through the design of a network model which uses dynamic segmentation. And we tried to implement efficient hierarchy model at the retrieval of the network and presentation. Designed model supports a stage presentation of various level and a hierarchy entity relation and We are expected to supplement a network spatial modelling function which the GIS has.
