Factros considered building the magnetron sputtering system for TFT LCD (thin film transistor liquid crystal display0 metallization were thin film thichnes uniformity, temperature uniformity and the pressure gradient of sputtering gas flow in vacuum chamber, base pressure, and the stability fo the carrier moving . The system was consisted of a deposition chamber, a pre-heating chamber, a RF-precleaning chamber and a load/unload lock chamber. The system was designed to handle a substrate with dimension of 400$\times$400mm. The temperautre uniformity of a heater table developed showed $250 ^{\circ}C\pm$5% accuracyon the substrate glass. A base pressure of 1.8 $\times$10-7 torr was obtained after 24 hours pumping with a cryo pump. After an aluminum target was installed in a sputtering source and the film wa sdeposited on the glass, the uniformity, reflectivity and sheet resistance of the deposited film were measured.

The purpose of this study was to identify kitchen and non-kitchen use of space for cooking and dining. Three rural villages, Kum-sung Ri, Young-san 1 Ri, and Yu-bang 2 and 5 Ri were selected for this study. Present and past use of space for cooking and dining was investigated by the field survey method. The major findings were that : 1) Both the kitchen and other space such as the outdoor courtyard(madang) were the space for cooking. 2) Dining activities took place in ondol rooms, the wooden floor room(maru), outdoor court yard(madang) and kitchen. In the winter eating activities took place in the kitchen where heating is provided. Many village people ate at a Western style or at a Korean style dining table(papsnag) in the kitchen. 3) Compared with study I, the present research found similar use of space for cooking and eating, with slight differences in space for eating.

"Bok Sik Bang', a book of cooking, was written in Korea in the 17 th century Various Cooking methods Of traditional foods were described in this book. 1. The kinds of cooking foods were Wine(59), Side dish(39), Seasoning(12), and Dessert(5) 2. The materials used in the cooking foods were cereals, vegetables, fishes, meats and etc. 3. The cooking methods were different and complicated. 4. The way of heating were also different such as to stew, to boil, to pan-boil, to frying, etc. 5. Utensils and table wares used for processing and cooking were poor and specific. 6. The measuring units were not accurate and unscientific. 7. Many of special words and expressions which are not used today in cooking and processing were reviewed.ewed.

This paper shows a design and implementation of throttle valve controller for engine dynamometer system using fuzzy logic. Recently, we demanded the excellent measuring equipment so as to improve engine performance. The throttle valve control for engine dynamometer system is a very particular part in the engine control. Since the structure of engine dynamometer system is very complicated and has nonlinear elements which are influenced by disturbance of vibration, heating, cooling, and energy loss so on. In this paper, fuzzy logic control application have been successful in throttle valve control problem for engine dynamometer system in which the conventional control had difficulties dealing with the system. In this study, we propose a method that the control strategy uses Fuzzy Look-up table and normalization and obtained the satisfying result from realized throttle valve controller for engine dynamometer system.

Objectives of this study are : 1) to utilize capillary theory and obtain pore-size distribution profiles from moisture-suction relationships using Laplace theory. 2) to investigate the behavior of Light Non-Aqueous Phase Liquids(LNAPLs) in the subsurface environment and to develop several predictive relationships which can be used to assess the effectiveness of various LNAPLs remediation technologies. The relationship to predict pore-size distribution function expressed in differencial equation is found by using capillary theory. Also, experiments are conducted to : the various LNAPLs subjected to vadose zone drainage, groundwater table drainage, waterflooding with surfactants. The experiments are performed with #2 heating oil, jet fuel. and kerosene. Several relationships have been derived describing the effect of various properties and process parameters on the LNAPL residual saturation.

본 연구목적은 열간압연용 런-아웃 테이블 롤러 표면의 기계적 성질을 개선하기 위해 다공질 자용성 합금으로 피복하는 방법을 개발하는 것이다. 열간압연에서 런-아웃 테이블의 롤러 내구성을 높이기 위해서는 고온에서 롤러표면의 경도를 높게 유지해야 하고, 내마모성, 내식성, 내열성, 내소부성 및 내응착성의 향상을 유지하여야 한다. 또한, 고온의 열연 강판을 안정적으로 이송할 수 있도록 하기 위해서는 롤러표면에 적절한 마찰계수를 유지하도록 하여야 하고, 롤러와 강판 사이에 미끄럼 발생이 없어야 한다. 본 연구에서는 자용성 합금에 텅스텐카바이드를 첨가시켜 서메트화하여 롤러의 내마모성을 증대시켰고, 미세 철분말을 롤러표면에 피복하여 다공질을 만들어 마찰계수를 높이고 붙잡음성을 향상시켰다. 그 결과, Ni-Cr 피복 롤러에 비하여 다공질 자용성 합금 피복 롤러는 피복층에 철분이 5 ~ 10 wt%로 많이 함유되어 재용융 공정에서 전기로로 가열하여 일부분만 합금화되고 나머지는 산화 및 용해에 의해 탈락되어 다공질로 나타나 강판과의 붙잡음성을 향상시켰다.

Zero energy building was attended for energy consumption minimization by the energy saving technology about building heating and cooling energy consumption and the renewable energy production facility. So the government has supported the zero energy building supply for decreasing green gas emissions. The study about inventory of zero energy building has many proceeding. That inventory need the information of material and equipment. So information of material and equipment about zero energy building must be included for the zero energy building realization. Actually the database of zero energy building inventory construction through the inventory established studies has difficult because the database need many information. In this study, author proposed the test methods and performance reference for upload at inventory. It was constructed to material - module - package. Also the author analyzed the construction of the technical package for zero energy building. The author separated performance category to the energy performance for energy analysis and other performance for confirmed the durability, stability and etc. This performance category proposed the table. The test methods of material and equipment in the passive package and active package proposed to the international standard and korea standard basically korea standard. Also the performance reference was proposed to korea legal standard and various standard by this study results. And the authors proposed the table of performance value, test methods, performance reference. By result of this study, the test methods and performance reference will be used the basic data for inventory of zero energy building.
