The purpose of this study was to identify and categorize the space use characteristics of the university professor's office. The data were recorded and collected through the physical trace method. Acture Measurement. Photograph, sketch and CAD drawings were used to trace 118 professors offices at Yonse-University. The analysed features were the user characteristics, the size, characteristics of space (such as composition, layout and furniture arrangement), the appliance and the instrument characteristics. To categorize the 'space use' characteristics. 6 variables were used: 1) the territorial characteristics, 2) the spatial relationship between professor's territory and entrance, 3) the layout type of work area, 4) the spatial relationship between professor's and assistant's work area, 5) the arrangement of table, and 6) the completion of sofa set. The results of this study are expected to be used as a basis for the development of design alternatives for the most typical university professors' office.

The purpose of this study is to analyze the varying characteristic factors for residential kitchen remodeling according to contemporary life style. The subjects of this investigation are collected through questionnaire from adult residents who live in Seoul, Korea. The collected cases are analyzed by using Spss-win. By using the vaimax method on the basis of factor analysis, the satisfaction of the actual conditions is under the influence of finished materials & function, sanitary installation, layout, cooling & heating apparatus, day lighting, air conditioning, and safety. The preference of kitchen remodeling Is affected by finished materials, function, environmental equipment, and air conditioning. The Need of kitchen facility is caused by working table, refrigerator, gas range, dish apparatus, and addition function.

This study is focused on acquiring through understanding of the S&T level of Korea to serve as an important basis for the government policy-making and to make available basic information for promoting the National R&D Program effectively. the survey of S&T level is a comparison of the highest level in the world to that of korea in 3 digit of the technology tree table. And survey of technological gaps is determined by year which Korea is able to reach the current level of the advanced countries. The results of the surveys should be applied to strategic technology planning for solving or nar-rowing the technology gap and the major criteria for resources allocation in national R&D Pro-grams. The results of he surveys should be the fundamental information for establishing strategic S&T policy in government.

In this paper, we present empirical testing result to examine the validity of inbound supply and outbound demand risk factors in the sense of early predicting the firm's bankruptcy risk level. The risk factors are drawn from industry uncertainty attributes categorized as uncertainties of input market (inbound supply), and product market (outbound demand). On the basis of input-output table, industry level inbound and outbound sectors are identified to formalize supply chain structures, relevant inbound and outbound uncertainty attributes and corresponding risk factors. Subsequently, publicly available macro-economic indicators are used to appropriately quantify these risk factors. Total 68 industry level bankruptcy risk forecasting results are presented with the average R-square scores of between 53.4% and 37.1% with varying time lag. The findings offers useful insights to incorporate supply chain risk to the body of firm's bankruptcy risk level prediction literature.

This study aims to analyze how much KF-X production impacts on national economy by measuring economic spread effect based on inter-industry analysis. In order to evaluate the economic impact of KF-X production, we used input-output table of year 2007 of Korea. The results shows that KF-X production induces the production of 3,129 billon won and the value added of 1,206 billon won respectively. Also there are the creation of about 13,208 employment in the industry. The results from this study can be used as a basis for the further research on whether or not KF-X production could be processed.

This study aims to investigate the residents' and village leaders' complementary demand for the regional economic vitalization and 6th industrialization in the rural. Based on the field expert'(the head of the village or the chairmen of the farming association) interview, the study was conducted. For the study, 42 villages where selected to consider as 6th industry. Cross table were conducted to see if there were any differences of demand and consideration for between the type of 6th industries. This article further improve the rural environment for 6th industrialization, improve the policy measures in that rural can plan the basis for an effective strategy can be.

A steganographic method using three directional data embedding for gray images is presented in this paper. Cover image is divided into non-overlapping $2\times2$ sub-blocks and the basis pixel is selected to calculate the three different values of each sub-block. Difference values are replaced by embedding the number of secret bits that is referenced by the range table. For the three pixel pairs in the sub-block, the optimal pixel adjustment is preceded to reduce the distortion of visual quality. The experimental results show that the proposed method achieves a good visual quality and high capacity.

Average throughput estimation of EV-DO forward link is implemented on the basis of the serving coverage area per sector instead of time consuming and complicated Monte Carlo simulation. For the implementation of this analysis function in cell planning tool, $CellTREK^{(R)}$, developed by KT, both SNR vs. DRC mapping table and receiver sensitivity are suggested as the satisfying criteria to be satisfied above each threshold level simultaneously.

The control method which electrically subdivides 1 step(1.8\ulcornerstep) of a PM step motor into 64 micro-step (0.028\ulcornerstep) is realized using micro-step algorithm on the basis of the look up table method and the position and velocity control using Z-80 microprocessor is also realized. With micro-stepping. The resolution of the system is improved, also by micro-step control of driving-current of the step motro, which is followed by the increase of micro-step subdivision-coefficient, the precise position and velocity control of step-motor can be realized and the stabilization of the system is improved.

The seismic characteristics with Friction Pendulum System have been studied using a shaking table system. In this study, we made two kind of floor system (Type I, Type II) and several seismic tests with and without isolation system were conducted to evaluate floor isolation effectiveness of Friction Pendulum System. Both type have showed large reduction effectiveness in acceleration, response spectra but Type II have showed lower acceleration and lower first mode in response spectra, compared to type I. On the basis of test results and consideration of application, it is found that type II is more suitable for floor model of main control room of Nuclear Power Plant.
