As the IT industry rapidly progresses, the functions of electronic devices and display devices are integrated with high density, and the model is changed in a short period of time. To implement the integration technology, a uniform micro-pattern implementation technique to drive and control the product is required. The most important technology for the micro pattern generation is the exposure processing technology. Failure to implement the basic pattern in this process cannot satisfy the demands in the manufacturing field. In addition, the conventional exposure method of the mask method cannot cope with the small-scale production of various types of products, and it is not possible to implement a micro-pattern, so an alternative technology must be secured. In this study, the technology to implement the required micro-pattern in semiconductor processing is presented through the photolithography process and plasma etching.

It is well known that tire pattern design factors have a large influence on overall tire performance. In this paper, the basic study on the effects of tire pattern design factors on tire labeling performance has been carried out through experimental tests. The pass-by noise is affected by tire pattern design, by a maximum of 2.7dB(A), and the number of sipes gives large effects on PBN. The rolling resistance is also influenced, mostly by the number of longitudinal grooves and secondly the number of sipes. Finally, there is a weak correlation between PBN and RR when the pattern design factors are changed.

The purpose of this study was to investigate the dweller's housing needs through the connection between dwellers' living pattern and space usage. The objectives were (1) to examine how to eat and cook in the eating and cooking spaces, (2) to examine how to alter the original housing, (3) to research the dwellers' housing needs for the eating and cooking spaces, and the changing process of dwellers' housing needs, and (4) to classify the type of eating and cooking spcaces. The results of this study were (1) there were changed in eating pattern of space usage according to the season. The eating activities were a Korean living pattern : sitting on the floor and eating at the BAB SANG. (2) There was a difference in the pattern of space usage and the activity for main cooking and KIM CHI. (3) AN BANG (eating space for winter) as well as MARU (eating space for summer) has changed to a larger space. (4) By the changing of living patterns, BU AUK (a main cooking space ) has showed a various alternations: function, dimension of space, facilities, floor materials and floor level. (5) The dwellers' housing needs for eating space were a multipurpose room, and a dining kitchen of western living pattern (using a dining table and chairs) with the present changing life styles. (6) The dwellers' housing needs for cooking space were a multipurpose room of working area, a seperation of heating area, a western living pattern, a plan of flat fllor level and a dining kitchen. (7) BU AUK of eating and cooking spaces was classified into 4 types: a traditional type, a mixing type, a modernized type, and a western type.

Typhoon Rusa passed over the East China Sea and crossed over the Korea Peninsula on August 31, 2002. The core of the typhoon passed directly over a data buoy mooring site at ($127^{\circ}45'E,\;34^{\circ}25'\;N$) and several ARGOS-tracked drifters capable of measuring salinity. Peak hourly mean wind speed reached 28 m/s at the mooring site and wind pattern in the East China Sea changed from southerly wind to northwesterly wind after the typhoon passage. Two or three days before the typhoon tile drifter displacement changed significantly and the region-wide circulation pattern changed from a northeastward current to a westward current one week after the typhoon had passed. The surface water in the East China Sea was cooled to about $4^{\circ}C$ under the typhoon core and a general cooling occurred in most of the East China Sea with the exception of the Chinese coast. The salinity as observed by the drifters in the East China Sea increased about 2 psu but the near-shore water along the Korean coast observed by the mooring was freshened about 3 psu. The freshening of near-shore water was caused by an intrusion of off-shore water rather than local freshening by typhoon precipitation.

The purpose of this study is to examine how Korean changed and applied the railway official residence space constructed by the Japanese, when they occupied these railway official residence space after liberation from Japan, and specify the relationship between the life culture and residence space by analysing the differance in important life style, as well as element of change in important residence spaces according to modernization. In addition, this study was carried out by means of research on the form and pattern, visual anthropological method by photograph and direct observation.The result of this study is summarized as fellows. The residence space at Kyounaju constructed by the Japanese on the basis of the culture has been changed and applied to the life style of the Korean when the Korean occupied these Japanese style residence space.Then, it seems that the change of the Japanese style residence was caused by both differance in the life pattern between Korea and Japan, and the medernization of the life.

Syndecan-4 cytoplasmic domain was tested to confirm the interactions with the bilayer membrane using $^{31}P$ solid-state NMR measurements. Syndecan-4 was known as a coreceptor with integrins in the cell adhesion. The syndecan-4 V region is not understood of its functional roles and tested its ability of the interaction with multilamellar vesicles. The $^{31}P$ powder pattern was dramatically changed and showed isotropic peak which imply the bilayer membrane changed its topology to the micelle-like structure. Especially, phosphatidylcholine membrane was affected this effect more than phosphatidylethanolamine membrane.

In the North-eastern districts of China, Northern races inherited and developed their own cultural traditions. The housing of northeastern China has been changed under the influence of environment. Some tribes' housings has been developed, keeping their own peculiar style, while others have divested of their ethnic flavor. To understand these aspects of development, this study focused on the housings in Heilongjiang and Nei Monggol. As for the procedure, this study referred to the literature and carried out a field trip at the same time. The housing of northeastern China has undergone the process to fix their residence after the life of migration in common. In this process, northeastern hosing has changed variously and can be grouped into the several types by shape and material. From the point of view about living pattern, some important living features are extracted by the types.

The terrestrial laser scanner measures the signal delay time of electronic circuit in EDM(Electronic Distance Measurement) Module for distance measurement. To measure signal delay time precisely, transmitting laser beam of terrestrial laser scanner is divided optically. Therefore, 10% of the laser beam power is entered into the electronic circuit and the others go out through lens. But, measure of delay time is severe in the laser scanner system that the laser beam power is changed dynamically by reflectance of a object, because characters like gain of electronic circuit involving APD(Avalanche Photo Diode) and so on are changed by incident laser beam. Therefore, we adapt ND(Neutral Density) filter that has grid pattern to the laser scanner system to keep constant the incident laser beam power. In this paper, we propose the simulation program for efficient design of ND filter pattern. Finally, to affirm simulation program, we conduct the experimental test of simulated ND filter that has linearly transmittance change, and we consider the experiment result.

The purpose of this study is to suggest a individually fitted slacks pattern in order to help ourselves prepared for the days of the order-based production like the EC in the apparel industry. A pattern was designed to make the personal fit improved based on the present study and the analysis of the measurements and the body shapes. The main characteristics of this newly designed slacks pattern are as follows. To improve fitting, the pattern requires more detailed data such as front and back waist arc, front and back hip arc, hip depth, the gradient of hip. And for personal fitted pattern, knee girth was established in the proportion to the hip girth and the crotch curve was adjusted to the measurements after drawing and the side seam curve was changed according to the front hip type and the ease in waist and hip was established by the percentage. Slacks pattern was developed into an automatic drafting program. Through the sensory evaluation for the appearance and moving fitness, newly designed slacks pattern was turned out to be improved in personal fit espacially for the body type out of the average.

This study considered and analyzed the influence of changed clothing silhouettes on the textile patterns by investigating the changes of geometry patterns in response to the changes of western women's apparel silhouette in the 1960s. The period scope of research was limited to the 1960s, and the research object was set as the geometry patterns seen in the designer's high-fashion. The researcher investigated the clothing silhouette and the textile patterns in 1960s by reviewing the literature about domestic and foreign books, research papers, domestic and foreign fashion magazines, information on the Internet. For the western women's apparel in 1960s, some active, simple styles were popular under the social atmosphere when more women actively entered the society. Influenced by popular art trends at that time, the silhouette was expressed in the geometry pattern among many textile patterns. The geometry pattern either appeared as a regularly overall repeating geometry pattern and the regularly partial repeating geometry pattern. The regularly overall repeating geometry pattern arranged the straight lines in the same interval. But the regularly partial repeating geometry pattern was arranged without order to emphasize the motif in some parts of clothing or to give some ornament effect, or was arranged asymmetrically.
