In search of the improvement plan for elementary schools which aims at the efficient application of new educational programs according to the introduction of the 7th National Curriculum, the analysis results for the spatial configuration regarding the modernized elementary schools in Busan City are as follows: 1) The analysis of expansion in the building area reveals that the building area per classroom has been increased from $200m^2$ in 1995 to $350m^2$ in 2005 based on the data gathered from the constructed schools during that period. 2) While the ratio of classrooms per the gross school area has been decreased from 35% in the late 1990s to 20% in the 2000s, the entire school size continue to become larger, which is considered as desirable change. 3) New construction and addition of special classrooms and multi-purpose spaces have continued to be increased. Multi-purpose spaces were positively considered in the early 2000s, but recently built schools tend to limit the construction of multi-purpose spaces only to lower grades' space or not to obtain them owing to the analysis that its utilization is limited. 4) Most schools constructed after 1999 are equipped with dining hall and multi-purpose halls, and show the increase in their sizes. Especially, dining hall tend to be located on the upper floors for better environmental conditions.

Results of RF compatibility test between KOMPSAT(Korea Multi-Purpose SATellite) and TTC(Tracking, Telemetry, and Command) station are described. S/C(Spacecreft) RF Test, telemetry test, command test, ranging test, and tracking receiver test were performed with respect to pass/fail criteria. To provide physical RF interface between KOMPSAT and TTC equipment, direct low cable and antenna-to-antenna interface were implemented. Through RF compatibility test, it was fully demonstrated that KOMPSAT and TTC equipment are functionally workable.

For solving problems of manpower and improving working environment, Robot System have been introduced. In the past, Robot System was adopted mass production, indoor factory condition, but present Robot System is applied to many other fields. This applied field is Robot System was adopted fruit harvest, maintenance, and so on. The developed Multi-Linked Lifter is applied to eminant multi-purpose working. The purpose of this study is to develop control algorithm for this equipment composed of multi-linked manipulator.

In this work, we propose and design a GaN-based diode with a p-doped GaN (p-GaN) multi-well structure for high efficiency betavoltaic (BV) cells. The short-circuit current density (J_SC) and opencircuit voltage (V_OC) of the devices were investigated with variations of parameters such as the doping concentration, height, width of the p-GaN well region, well-to-well gap, and number of well regions. The J_SC of the device was significantly improved by a wider depletion area, which was obtained by applying the multi-well structure. The optimized device achieved a higher output power density by 8.6% than that of the conventional diode due to the enhancement of J_SC. The proposed device structure showed a high potential for a high efficiency BV cell candidate.

The purpose of this study is to analyze the multi-layered space utilized as strategy for deconstruction in the architecture of Hiromi Fujii. Although the design of Eisenman and Fujii was based on the philosophical theory of Jacques Derrida, there are many different aspects of architecture. At the same time, Hiromi Fujii could construct his concept of multi-layered space to colligate the academic knowledge of Jacques Derrida, Roman Jakobson and Colin Rowe. This kind of concept for multi-layered space is a critical element to be distinct from the characters between two architects, and it is implied such as an significant concept to analyze the architecture for Hiromi Fujii. This multi-layered space contains interesting and researchable value to understand and to analyze the western architecture theory from the viewpoint of Asian architect. Accordingly, the purpose of the thesis is to find the meaning to establish an theoretical foundation for being under discussion to the architecture of Fujii through the concept of multi-layered space.

Recently, in accordance with the cultural progress and the improvement of citizen's consciousness level, it is the real situation that the construction of small-scaled Multi-Purpose Hall where various cultural events could be performed, is on increasing. However, because the most of Multi-Purpose Hall had been designed and built up without any consideration on Acoustic Factor, many problems are on occurring thereat. Because those small-scaled Multi-Purpose Hall have been mostly used with the finishing material which contains a high degree of Acoustic Absorption indiscreetly, both diffusion and reflection of sound are not establishing properly, and since the reverberation of sound is very low, in case of musical performance by musical instrument, its sound hears too arid and stiff, there occurs some acoustic defect such as it becomes difficult for music appreciation with sufficient timbre, so that the capability improvement on the matter is urgently requiring situation. On this viewpoint, this Research has caught the Authenticity of the forecasted value and actually measured value using Acoustic Simulation on the subject of the small-scaled Multi-Purpose Hall, and then intended to propose the optimum acoustic condition on the basis of the Authenticity. As the result, it could be designed a Multi-Purpose Hall equipped with the satisfactory acoustic performance compare with the time before improvement, so that it is considered that such research result could be practically used as the fundamental material when design for other similar small-scaled Multi-Purpose Hall in the future.

There is imminent need to find a way to measure the recreational benefits of water so that appropriate actions can be taken to make a multi-purpose reservoir. Therefore, this study attempts to apply a choice experiment to quantifying the recreational benefits of a multi-purpose reservoir, using a specific case study of Sangkwan multi-purpose reservoir. We consider the trade-offs between price and attributes of recreational attributes for selecting a preferred alternative and derive the marginal willingness to pay (MWTP) estimate for each attribute. The results show that the MWTP for providing additional 10,000 ton of water is estimated to be 3 won per household per year. The MWTP for improving 1 level of water quality is computed to be 645.5 won per household per year. Moreover, the MWTP for providing recreation facilities is calculated to be 1,518.6 won per household per year. This study allows us to provide policy-makers with useful quantitative information that can reduce uncertainty in the decision-making process related to a multi-purpose reservoir construction projects.
