This study shows the result of the survey conducted for male adults who had to use wheelchairs. The objectives of this study are to develop and improve the clothes for the disabled people and to make those garments put into practice. For this purpose, the survey was conducted at first so as to understand the situation of the disabled peoples wearing clothes and the garment demands. This survey is to suggest the suited form of the pants they want. The result of the study is as follows. 1) The average age of the subjects was 38.4 years old. They have used wheelchairs for 12 years on the average. Most subjects two limbs were paralyzed because of the acquired spinal paralysis. 60 percent of them were wearing the urine bags all the time. The average size of the pants they purchased was 39 inches, which means that their waist and abdominal circumstance were very big. 2) Regarding the situation of wearing habits, although the subjects usually purchased ready-to-wear, most of them are very dissatisfied with them. Especially, they considered the size as their main dissatisfaction. The main concern for buying garments was how comfortable and mobile they are while wearing them. They also needed outdoor garments. Lastly, they looked forward to the shop specialized in the garments for disabled people. 3) The functional pants for adult men using wheelchairs had the same zipper as that of general pants. The waist belt was made of rubber to reduce the pressure on waist and to cover 2 inches (5 cm) of waist circumference. Also it should be made to secure each button within the belt in accordance with size. Finally, it was designed as formal wrinkled pants that had pockets within the reach of hands when the disabled used wheelchairs.

The purpose of this study was to analyze the signification system between color and clothes systematically in black and white clothes. For this purpose, after examining the images of black and white clothes, we selected 55 clothes that represented as black and white and analyzed their meanings and the sources using semiotic framework, based on the work of Saussure and Barthes. The results as follows: First, the meaning in black and white clothes was generated from original color image. White clothes of religious person like Virgin Mary, Angel expressed pure and sacred color image. And black clothes like funeral dress expressed grief and death. Next, the meaning of black and white clothes was regenerated into modern color image by new environment. After industrial revolution, black was considered as a traditional men's fashion color. With diverse leisure activities, white sports wear appeared as active and clean image. Finally the source of the meaning of the clothes was the designer or the wearer. A little black dress by Chanel who was interested in simplicity and function represents an ideal of simple and sexy object. The situation is complicated by the fact that these three kinds of explanation may be found singly or mixed together.

The screw compressor is first invented by a Swedish engineer, Alf Lysholm in 1934. Since then, the development of the screw compressor idea for industrial applications has been continued by the Swedish research organization Svenska Rotor Maskiner, often identified by its initials SRM. The first industrial application of the machine was marketed as an air compressor in the 1950s. The screw compressor which is a positive displacement type compressor compresses gases by the rotation of a pair of mating rotors. The operation of this compressor is entirely rotary and dynamically in balance. Also there is no need for any valve mechanism and there exists less mechanical wear between the parts compared to the conventional reciprocating compressors. Due to these prominent features, the screw compressor has been rapidly spread into the air compressor market replacing the conventional reciprocating compressors and begun to be applied as a refrigerant compressor since the 1960s. In this work, the operation principle of the screw compressor is described in brief and the major design parameters affecting the compressor performance are classified. The international research trend in screw compressor development is introduced and the current situation in our country is described.

In this paper, we designed the RFID(Radio Frequency Identification) Emergency Medical Information System(REMIS). This REMIS offers the emergency patient's medical information using RFID and HL7(Health Level 7) to an emergency medical technician. In emergency situation as like coma, if the communication, from the patient's current location to the hospital, is possible, REMIS offer the medical information of the patient through REMIS server to an emergency medical technician. In the state of communication blocked, REMIS can offer the patient identification and the emergency information through RFID tag, which the patient wear, to an emergency medical technician. When this system was designed, the protection of the patient's medical information and their privacy was considered, and the HL7 was used to be compatible with another medical systems. Therefore, in this paper, REMIS was designed that it is always possible to offer the emergency patient's information to an emergency medical technician regardless of any communication status and to improve the emergency rescue process, effectively.

Many automotive companies are endeavoring to improve the quality of resistance spot welding by updating body-in-white (BIW) production line with adaptive control spot welding system to compensate the process disturbances such as gap, electrode wear, oxidized surfaces, poor fit up and adhesive etc. Most of the commercial adaptive weld controllers require proper "Initial Welding Schedule" or "Reference weld" to achieve compensation in welding parameters during real time welding. In this study, the compensation of a commercial adaptive weld controller had been observed and analyzed thoroughly for various process disturbances to find optimal initial welding schedule. It was observed that 90 percent of the expulsion current in constant current control as reference welding schedule conferred the maximum button diameter in adaptive control welding. Finally, effects of each disturbance in combined field disturbances system with adaptive control had also been confirmed with the design of experiment (DOE) by minitab(R)16 for combined disturbances situation and suitability of optimum initial weld current had also established with real body part validation test.

Although the system for establishing grinding operation standards mainly depends on the simulation method, it is desirable to obtain highly reliable grinding data and to develop experimental technology, And, it also needs to modify the simulation models if the simulation results do not coincide with special situation due to the difference of grinding machine, wheels and workpiece materials. If simple tests are carried out to evaluate these specificity, the reliability and utility of the system can be raised higher. Therefore, it is required for evaluating wheel ability and confirming the validity of the experimental methods as well as the possibility of exchanging the experimental data between Korea and Japan to preform several kinds of grinding experiments. In this paper, experiments of cylindrical plunge grinding were conducted using the wheels of the same specification made by three typical grinding wheel manufacturers both in Korea and Japan, respectively. The grinding power consumption grinding force, the ground surface roughness, and wheel wear were measured under the same dressing the grinding conditions. The average value and standard deviation of the experiment results were calculated to compared the grinding performance of the wheels made in both countries. The experiment results show that the grinding wheel performance of Korea's is nearly equal to that of Japan's for general purpose of grinding operation. In conclusion, it is possible to exchange the experimental data between Korea and japan.

In this paper it was observed that the influences of social environment that had been saturated by the modern awareness and west-ern culture effected largely on clothing. Also it was studied how and by what en-vironmental factors the costume during the enlightening period was accepted and devel-oped in Korea relative to social cultural en-vironment. In this research the emphasis was placed on the process of changing to western clothing especially the influence of Group Clothing on the general women's clothing. Therefore the types of group clothing and its influences were studied. in this study the types of group clothing recalled were modern women's clothing mission-ary women's clothing professional women's such as nurse uniforms school girls' uniforms and the invention of women's sports wear. And lastly it was searched for the direction of developent in apparels. From the above mentioned we can conclude that the clothing is inseparable from social and cultural Invironments and foreign affairs of politics at the time. Also it is considered that the types of group styles were the necessary happenings in the early stage of modern so-ciety. Because of historical situation in Korea the western clothing style had taken place in a short period of time. however Korean women's clothing which had been centerred around group clothing was considered to have changed from Korean traditional costume to western clothing by rational decisions of modern awareness in-stead of sudden change from traditional clothing to western clothing by indiscrete acceptance of western culture.

With the beginning of seventeenth century, the men in France royal palace began to wear wigs and by eighteenth century wig became sole possession of men. Then, it had been become a satire thing filling one side of the era with the pouf that had been for women. All these things were closely related with the unstable social situation. The bourgeoisie expressed the anger for the privilege that come from the disparity of class consciousness. The reaction against the discriminative treatment by the illuminists stimulated the outbreak of the French Revolution on 14th, July in 1789. This paved way of characterizing the wig styles of the time. The symbolism of cultural-historical meaning in the west is not confined only in Europe. The worship of hair that is different from one cultural area to another had started with their own unique taboo consciousness and had developed to the form speaking for the expression of masculine, the symbol of man power and the extravagance of the privileged class.

Due to recent changes in increased life expectancy, economic power and social development, the new senior generation (focusing on people in their fifties) represents a new market power with strong competitiveness. The new senior generation is the generation after the baby boomers, with characteristics that include a high-level of education, increased income, a high-level of consumption, increased assets, self-fulfillment desires and individuality. Demands in the senior fashion industry are expected to gradually increase and the underwear industry that targets the new senior generation is expected to grow rapidly. These demands will require product development for the new senior generation based on emotional and socio-cultural characteristics. The current new senior underwear market is under the process of R&D with a focus on body shape changes; however, there are limited studies on emotional and socio-cultural approaches. This study formulates a basic design plan for different age groups based on an analysis of the situation of bra wear (current inconveniences, demand and needs) by women in their fifties and over. Subsequently, a functional active bra top that considers activity and comfort was proposed for women in their fifties, an all-in-one foundation bra top that shapes the body was proposed for women in their sixties, and comfort bra tops that are comfortable and easy to put on and take off were proposed for women in their seventies and over.
