As we have come to realize the problems caused by the modern civilization as well as the importance of the preservation of nature. Ecological building and urban design come to attract more attention. Therefore, the object of this study is providing the design factors and improving the design methods for the developments of ecological housing complex, harmonious with environment. Followings are the results of this study: 1. We need to turn to new trend-Ecological architecture which enables the co-exitence of nature and human being to come over the presence and face new decades. 2. Ecological architecture is based on energy-saving system and give people a healty and comfortable atmosphere. 3. In the city area, the house development should be undertaken to minimize the environmental problem through extremely high ehhiciency and technonogy. 4. We need a new development to preserve natural environment in the suburvan and small or medium city. 5. We have to develope the approach method, which is to maintain the frame of present ecological environment, to be in sympathy with geomorphology, to use the natural material in the rural community.

This paper studies in terms of nonverbal communication the roles of Gut-clothinbgs used in Jin-Do Sit-gim Gut are classified as follows: 1) The message communicated through the ordinary clothings of a shaman is that he or she is waiting to serve as a presider of a Gut ceremony actiong as a mediator between the spirtual and the human world. 2) The shaman clothings representing many kinds of spirits are visualized figures which are closely related to the common wishes of most people in society e. g. physical and material well-being longevity fertility. 3) The clothings serve as a body figure in the Gut are classified into 5 groups. (1) Laid-on clothings give the message that the body is standing still. (2) Wrapped clothings serve as an incarnated body of the dead. (3) Spread clothings represent a lying body. (4) Oscillated clothings are the symbols of a spirit which moves from this world to another. (5) Burned clothings mean that the spirit has attained a complete seperation from this world.

This study was conducted to investigate the health effects of the general components of acorns in animals. In Korea, acorns have been used as food material in the form of acorn starch. Acorns contain tannin, gallic acid, digallic acid, and gallotannin. Therefore, the health effects of acorns as functional food are actively being studied. The chemical composition of acorns may vary according to the harvest time, region, and breed. Acorns have excellent antioxidant properties and might be beneficial in controlling hyperlipidemia, obesity, cardiovascular disease, and dementia, as well as strengthening immune competence. Further study is necessary to better understand the benefits of acorns, as it is expected to represent a large part of the food industry.

Recently there have been media reports of some domestic FA refinement factories that omit the refinement process and ship raw material directly, for production time and cost reduction purposes, resulting in a negative effect on concrete quality. Accordingly, it's expected to have a negative effect on concrete quality. So this study seeks to clarify the impact that FA quality has on concrete's engineering characteristics, using various FA from refined FA being circulated in the nation to reject ash discarded during the refinement process. The results showed that when FA is used, liquidity is enhanced than when only OPC is used in the combination, and when refined FA is used air quantity and intensity increases as well.

This paper is a study on the 'primitivism' which is constantly being applied on modem and contemporary textile design as a aItanative expression of the serious environmental phenomena of materialism. Starting with the analyzation of the 'concept of primitivism' , this paper is to research the 'origin of primitivism' which was first recognized by the modem artists. Primitivism on modem textile design will be suggested through 'trend terms'. The purpose of this paper is to be a basic material source for the creative development in design as well as to be of help in development of theoretical the study on contemporary textile design.

Recently, importance of working environment is increased in commercial vessel and offshore structure. Marine facility design and ambient environment condition are influenced to enhancing human performance and reducing human errors. Consequently, the quality of accommodation where offshore facility crews sleep, eat and relax will influence their job performance and overall sense of comport and well-being. Therefore, adequate acoustic isolation between adjacent spaces is normally required to achieve satisfactory internal noise levels, acoustic privacy and speech intelligibility. In this study, the reverberation time is investigated in the public areas where there are not provided the information of material's noise reduction coefficient (NRC). The experiment of reverberation time is rarely performed for the various type public areas in a marine structure. Therefore, the reverberation time in a vessel is investigate in order to evaluate the room's noise reduction coefficient (NRC) in a public area.

Recently, in the food, paper, steel and plastic industries, plate or sheet type products have been produced by the rolling drum. Steam heating drums are introduced into plastic products facilities in order to keep the density, microstructure, and strength of material uniformly. The drum journal can not help being concentrated by stresses due to the bending and torsion. Especially the drum, heated by high pressure steam, might be exposed in the steam leakage accident. First of all, the stresses on the steam drum journal are to be analyzed, and a case study proper to the subject was performed with a scraped journal, in order to investigate the failure characteristics as well as the initiation and propagation of fatigue cracks, and most probable circumstances of crack initiation. As the result of this study, it is suggested that newly installed drum journal be thoroughly inspected at the next periodic maintenance intervals for evidence of cracking, the microstructure examination and hardness measurements to prevent steam drum from the failure accident.

As the structure, material and construction of building develop continuously, so the recent residential buildings are being large, high-rise and group. High-rise residential buildings consume a lot of energy on supplying cold and hot water. As well, high-rise residential buildings bring on discomfortable use and unexpected conditions on account of faucet outlet pressure rise and the difference of water supply pressure between top floor and bottom floor. Thus, the purpose of this study is to research on using conditions of cold and hot water supply system through survey and field measurement in high-rise residential buildings and to analyze problems.

Welding characteristics of STS304 stainless steel and Inconel 600 using a continuous wave Nd:YAG laser are experimentally investigated. Alloy 600 being used in steam generator tubing of pressurized water reactor(PWR) exposed to some corrosion environment, stress corrosion cracking can occur on this material. Presented here are the results from a series of experiments in which dissimilar metal welds were made using the gas tungsten arc welding process with pure argon shielding gas. But It is well known that solidification cracking susceptibility of austenitic alloys depends on the solidification temperature range and amount/distribution of solute rich liquid that exists at the terminal stages of solidification. An experimental study was conducted to determine effects of welding parameters and to optimize those parameters that have the most influence on eliminating or reducing the extent welding zone formation at dissimilar metal welds.
