  • 이 연구는 화재현장 등에서 수직 강하식 구조대를 이용한 비상 탈출 시 안전한 팔 자세에 관한 것이다. 실험결과는 다음과 같다. 첫째, 양팔을 위로 뻗은 자세는 구조대의 포대 내피 및 협축부와의 접촉이 최소화되어 실험대상자 모두 찰과상이 발생하지 않았다. 둘째, 양팔을 벌린 상태에서 구부린 자세는 팔꿈치가 포대 협축부 및 내피와의 마찰로 인하여 실험대상자 모두 팔꿈치에 가벼운 찰과상을 입었다. 셋째, 양팔을 가슴에 모은 자세는 신체가 협축부를 통과하면서 포대의 협축부 및 내피와의 마찰이 생겨 실험대상자 모두 팔꿈치에 가까운 찰과상이 발생하였다. 넷째, 양팔을 아래로 내린 자세는 하강 시 다리를 어깨너비만큼 벌린 상태이므로 손등에 포대의 협축부 및 내피와의 마찰이 생겨서 손등에 가벼운 찰과상을 입었다. 마지막으로 양팔을 전면 아래로 모은 자세는 신체의 전면 부피를 증가시켜 경미한 손등 찰과상이 발생하였다. 향후 연구과제로 하강 시 적합한 다리 자세와 지면 착지 시의 자세도 연구할 필요가 있다.

  • Cellulose production by Acetobacter pasteurianus was investigated in static culture using four bioreactors with silicone rubber membrane submerged in the medium. The shape of the membrane was flat sheet, flat sack, tube and cylindrical balloon. Production rate of cellulose as well as its yield on consumed glucose by the bacteria grown on the flat type membranes was approximately ten-fold greater than those on the non-flat ones in spite of the same membrane thickness. The membrane reactor using flat sacks of silicone rubber membrane as support of bacterial pellicle can supply greater ratio of surface to volume than a conventional liquid surface culture and is promising for industrial production of bacterial cellulose in large scale.

  • This study aims to analyze the style of men's suits and extract expressional words for the development of semantic differential scales of visual images according to the change in silhouette. Research methods are literature studies, case studies, and questionnaires. The stimuli were created using CLO 3D, a virtual sewing CAD. This study's results are as follows: 1) The British suit jacket has an angled shoulder line using thin pads, and a slightly higher waistline. The pants of the suit have a high waistline and two pleats, so the thighs of the pants are wide. The American suit jacket has a natural shoulder line, and the waistline is not emphasized. The width of the jacket is relaxed, and the length is long. The pants of the suit have a higher waistline, and the pants are wide as well. The Italian suit jacket has wide shoulders, and the waistline is connected lower with a soft curve, and the length is relatively short. The trousers of the suit are tapered and get narrower as it goes down to the hem. 2) Because it originated in the practices of true bespoke tailoring, traditional British suits have a far more 'fitted' silhouette than the mass-produced styles that became emblematic of the American style. By the late 1950s, a sack-style suit was standard American business attire. This technique gives the sack suit its characteristically 'boxy' silhouette. The "Continental" presented a highly tailored silhouette, with padded shoulders, a slim, tight-fitting chest, and a closely tapered waist. The story was that Italian culture valued aesthetics over all else and thus sought the 'slim' suit style as much as possible. 3) The main expressional words of visual images for men's suits differ greatly depending on the silhouette of suit. The visual images are ranked in the order of 'neat', 'classic', 'educated', 'hard', 'mature', for fitted silhouettes. The words of 'masculine', 'basic', 'comfortable', 'simple', 'mature', 'conservative', 'modern', are ranked for boxy silhouettes. And the words of 'slim', 'young', 'neat', are noted for slim silhouettes.

  • So far, for pearl culture using abalones, a plastic nucleus has been planted in an abalone by perforating the shell. But after planing 80 % of abalones died, and even if they live, the pearl's hardness was not so good. The weak hardness made the pearl valueless. The quality of a pearl is decided by the gloss and the quality of the pearl's layer. This study is to find the right nucleus for abalones and to decrease a death rate of abalones by selecting the right planting place. This study was also performed to obtain valuable pearls with proper size, gloss, and good color. Below is the result of the research; Conch shells out of the various nucleus materials were the best. Their shape, color and gloss were very good. The nucleus was planted in the part that a shell is grown up under the absorption ball, as a result a pearl sack was quickly made. After 15 days, out of every pearl, pearl sacks were made. The pearl formation was measured every month. From the abalone shell which was planted in April, qualitative pearls which was from 5mm to 5.81mm in size were obtained in December.

  • The purpose of this study was to analyze the classification and meaning of symbols, of the clothes of the college students by sex-roll theory and identity theory. The clothes analyzed in this study were collected by photographs which were taken in the campus (240 out of 1,000 pictures) of the several colleges and universities in Seoul form fall in 1993 to summer in 1994. The results were as follow : 1. Analysis as a symbol of sexuality. The phenomenon of the visual inconsistency and consistency of sexual image in dress were showed simultaneously. The clothes of male students were generally becoming feminine style in materials and colors of clothes. These suggested that sex-roll theory be applied to their clothes. 2. Analysis as symbols of identification or individuality. The identification of shoes, bags, accessories, and hair styles were prominent than that of clothes. When it was analyzed as a symbol of individuality, the college students seemed to act as fashion leaders, who accepted new fashions and tried them on first. These suggested that Erikson′s theory on identity be applied to their clothes. 3. Analysis as a symbol of emblem. The dissimilarities of between the college students and other groups in the same generation were bright and casual attire with files, books, and sack. 4. Analysis as a symbol of campus ceremony. The clothes of college students on campus ceremonies were more causal and flexible than those of other groups in the same generation. It was known that the symbols showed above were reflected on their clothes as "one′s expressions" which are sex-roll, identity, and characteristics of college students.

  • During the period of 3rd Tae-Jong and 4th Se-Jong, Yi Dynasty has established sound basis for ruling power and aristocratic social cast system. And the regulation for official dress has also been firmly established during the same period. The establishment of KWAN BOK SACK (Office of Hat-Dress) in 16th year of Tae-Jong (1416 A.D.) and the enforcement of KWAN BOK JI JAE (System of Hat and Dress) in 8th year of Se-Jong(1426 A.D) indicates the completion of system of official dress in the dynasty. In this study, the author tried to find out the concept of color in the ruling society since the concept of color in KWAN BOK JI JAE, which is the social reglation in the fendal dynasty, had greatly been influenced by these class of people. Effort has also been given to investigate what motivated the establishment and enforcement of KWAN BOK JI JAE, through the descriptions revealed in SE-JONG SILLOK. It can be concluded in the first that, in KWAN BOK JI JAE no new color concept appeared and its significance only remains on the fact that it establshed the social regulations which were existed before. And secondly, the works of Se-Jong in KWAN BOK JI JAE, in contrast to his magnificance in other fields, only showed great influence of toadyism (Chinese culture).
