The purpose of this study is to develop and examine an in-line skating uniform that is also suitable for everyday wear, through research on the dressing needs of skaters. The results of this research are as follows: when asked about the garment, ordinary clothes were more inconvenient than professional uniform. In the case of the upper garment, the skaters who dressed in ordinary clothes felt the most inconvenience in the part of sleeve, back side of bottom and width. The skaters who dressed in professional in-line uniforms felt the most inconvenience in the part of neck girth, of sleeve, back side of bottom. In the case of the lower garment, the skaters who dressed in ordinary clothes felt the most inconvenience in the knee, crotch and hip. The skaters who dressed in professional in-line uniforms felt the most inconvenience in the hip and crotch. Damage due to wear was shown up the hip, knee, side of thigh and shoulder. The answer rate was high that the ordinary clothes usually wore out and the uniform used to tear out in the form of clothes damage. An appropriate sample pattern was made up, based on the problems revealed in the results of the questionnaire analysis. Evaluation of samples was used linear Measurement (5 point preference scale) by organized with 15 male and female's subjects group and 12 observer group.

Earlier works have shown that excessive shear stiffness at the steel-concrete interface causes a non-uniform distribution of shear force in composite structures. When the shear studs are wrapped at the fixed end with flexible materials with a low elastic modulus, the shear stiffness at the interface is reduced. The objective of this study was to investigate the effect of silicone rubber-sleeve mounted on shear studs on the shear stiffness of steel-concrete composite structures. Eighteen push-out tests were conducted to investigate the mechanical behavior of silicone rubber-sleeved shear stud groups (SRS-SSG). The dimension and arrangement of silicon rubber-sleeves (SRS) were taken into consideration. Test results showed that the shear strength of SRS-SSG was higher than that of a shear stud group (SSG), without SRS. For SRS-SSG with SRS heights of 50 mm, 100 mm, 150 mm, the shear strengths were improved by 13%, 20% and 9%, respectively, compared to the SSG alone. The shear strengths of SRS-SSG with the SRS thickness of 2 mm and 4 mm were almost the same. The shear stiffness of the SRS-SSG specimens with SRS heights of 50 mm, 100 mm and 150 mm were 77%, 67% and 66% of the SSG specimens, respectively. Test results of specimens SSG-1 and predicted values based on the three design specifications were compared. The nominal single stud shear strength of SSG-1 specimens was closest to that calculated by the Chinese Code for Design of Steel Structures (GB50017-2017). An equation is proposed to consider the effects of SRS for GB50017-2017, and the predicted values based on the proposed equation agree well with the tested results of SRS-SSG.

Since non-corrosive Fiber Reinforced Polymer(FRP) tendons have been in increasing use for underground and coastal structures constantly contacted with fresh water or sea water because of their superiority to metallic ones in corrosion-resistance, new non-metallic anchoring system for FRP tendons has been developed and investigated to verify the effectiveness of tendon force, which consist of mainly FRP pipes and Highly Expansive Mortar(HEM). The major factors considered in this experiment were expansive pressures of HEM during its hydration, sleeve lengths and types, and anchoring methods of tendon. New anchoring system were investigated from the pull-out tests. The pull-out procedures of the FRP tendons in the various pipe filled with HEM were analyzed and improved ideas were suggested to develop novel non-metallic anchoring system for FRP tendons The pull-out tests for the FRP tendon and new non-metallic anchoring system were conducted. The results show that non-metallic anchoring system for the FRP tendon has been more stablized due to the gradual expansive pressrure of HEM, as tims goes. Since tile lower stiffness of FRP pipes causes the weakness of anchoring force, it requires the increase of stiffness using a carbon fiber or an increased section area.

배경 : 기관지 소매 절제술은 종양이 기관지 근위부를 침범한 경우 전폐 절제술 후 폐기능의 감소가 커서 시행할 수 없는 경우에 폐실질을 보존함으로써 폐기능을 유지 할 수 있는 술식이다. 하지만 수술 수기의 난해함과 술 후 위험한 합병증 때문에 전폐절제술의 대 안으로만 여겨져 왔으나, 최근 많은 보고들은 다른 절제술에 비해 낮은 사망률과 낮은 morbidity를 보이고 있어 하나의 표준치료로 인식되고 있다. 본 논문에서는 기관지 소매 절제술을 시행받은 환자의 술 후 합병증의 발생률과 생존율을 분석하여 폐암 환자에 대한 기관지 소매 절제술의 타당성 여부를 조사하고자 하였다. 대상 및 방법 : 1989년부터 1998년 까지 서울 대학교 병원 흉부외과에서 기관지 소매 절제술을 시행받은 원발성 폐암 환자 45명을 대상으로 후향적으로 연구하였다. 남녀의 비는 40 : 5이었고 평균 연령은 57.4$\pm$9.7(23 ~72) 세였다. 수술 후 조직검사상 세포형태는 편평상피암이 35명, 선암이 7명, 선편평상피암이 1명이었으며 기타 2명이었다. 수술부위는 우상엽이 24명, 좌상엽이 11명, 좌하엽이 3명, 우하엽이 1명, 우중엽과 우하엽이 3명, 우중엽과 우상엽이 2명, 좌 전엽이 1명이었다. 수술 후 병기는 stage Ib가 11례, stage IIa가 3례, IIb가 16례, stage IIIa가 13례, IIIb 2례였다. 결과 : 조기 합병증으로 무기폐의 소견을 보인 경우가 9례, 7일 이상의 공기유출이 있었던 경우가 7례, 14일 이상의 늑막 삼출이 7례, 폐렴이 2례, 유미흉이 1례, 문합부 파열이 1례에서 있었다. hospital mortality는 3례 있었으며 후기 합병증의 대부분은 문합부위 협착에 의한 폐 허탈이었으며, 총15명에서 외래에서 기관지 내시경을 시행하였고, 이 중 7례에서 문합부위에 섬유화, granuloma, 허혈등에 의한 폐쇄가 관찰되었고 1례에서는 내시경으로 치료를 시행하였고 1례에서는 조직검사상 재발이 확인되어 방사선치료를 시행받았다 외래 추적 중 사망한 환자는 21례였으며, 흉곽내 국소 재발(동측 폐, 동측 종격동 임파선 전이)이 9례, 원격전이가 12례 있었다. 장기생존환자 42명의 평균 추적관찰기간은 35.5$\pm$29 개월이며 병기별로는 I 기 환자 11명은 모두 생존 중이며, II기 환자 19명의 3년 생존율은 63% 환자 13명의 3년생존율은 21%였으며 N stage에 따른 3년 생존율은 N0는100%, Nl은 63%, N2는 28%였다. 각 병기별 median survival time은 II기 59개월, IIIa기 16개월, Nl, N2는 각각 55개월, 22개월이었다. 결론 : 기관지 소매 절제술은 사망률이나 합병증의 발생률이 다른 술식보다 더 높지 않으며, 기능적인 면에서도 우수하여 폐기능이 나빠 전폐절제술을 견딜수 없는 일부 국한된 환자에서만 시행하는 것이 아니라, 기관지 근위부에 위치한 폐암에서 적극적으로 시행될 것으로 본다.

본 논문에서는 압축공기를 작동매체로 한 저압용 vortex tube에 대한 에너지분리 과정을 상세히 연구하였다. 먼저 vortex tube에서 에너지 분리되어 나오는 온공기와 냉공기의 온도변화에 대하여 실험하였고, vortex tube의 안쪽표면의 최대벽면온도 변화와 vortex tube내의 온도분포를 통하여 vortex tube내 유동장에서의 정체점의 위치에 대한 유용한 정보를 얻게되었다. 이를 바탕으로 vortex tube의 최적 길이와 throttle의 형상, sleeve에 따른 에너지분리과정 등을 실험을 통하여 알아보았다. 또한 본 연구에서는 디젤기관의 배기에 적용하기 위한 외통을 사용하였다. 이때 vortex tube에서 나오는 은공기가 180$^{\circ}$돌아 나오면서 vortex tube의 바깥쪽 벽면을 가열하게 된다. 이러한 기하학적 형상을 통하여 에너지분리효과가 증대됨으로 인하여 디젤기관의 배기가스에 적용 시 고온유동의 온도를 높이고자함에 본 연구의 목적을 두고자한다.

In this study I purpose a new approach to the study of Korean costume history which includes a statistical method used in the prac-tical measurement of excavated Po's and the analysis of their quantitative changes. In the framework used in this study I de-pend on the nineteen variables picked out from the typological and chronological analysis of excavated clothes. The interrelationship of the variables as well as the standard of each part and its deviation in other forms are may main concern. Other methods are also very useful in my thesis: Correlation analysis Regression analysis Discrimination analysis Cluster analysis Discrimination analysis Cluster analysis Factor analysis One way analysis of variance. The findings of my study can be summarized as follows: 1. Every type of po has a general tendency to have more broadened sleeves while it does not show any considerable changes in the total length and in the width of armholes. 2. In the Correlation analysis each part of Po's is handled separately accordign to its chronology and type. The Regreesion analysis makes it possible to provide the sizes of miss-ing parts in excavated clothes and the numeri-cal value of each part needed in the pattern making. 3. The Discrimination analysis of the Po's whose types are unknown leads to the con-clusion that Chongsam and Chikryong Po are classified into Chikryong Po whereas Hongui is classified into Jooui In addition I propose discriminational function by which the age classification is possible discovering the variables associated with time change. 4. Five items-Gerneral Park's clothes Taewongun's clothes and three others produced later for the purpose of preserving Korean costume are proved to be in a differ-ent group and hence analyzed separately in the visual grouping of changui which is done after the cluster analysis and the factor analysis. 5. The results of the one way analysis of variance reveal that there is a difference in each part from period: the back width the sleeve length the sleeve width thelean fig-ure the breasttie length the breasttie width outside quesset upper inside quesset lower outside neckband length insideneckband length etc.

The mainstay of modern fashion design has always been Western costumes. Though Asian costumes do get featured in collections at times, most instances are just instances of the western culture showing curiosity toward non-mainstream costumes. Until recently, Japan, which has been the most active in cultural exchanges, has been the main recipient of these curiosities, and has been used as the representative style and culture of East Asia. What needs to be let known is that Korea has its own costume style and culture, which have been developed according to its tradition and beliefs. Hanbok, which is the representative traditional costume in Korea, has existed since the beginning of the Kochosun dynasties. I started this study to figure out the design source of Hanbok's shape and develop it into a modern costume. In the fashion industry, "Mandarin Collar" and "Kimono Sleeve" are common terms, And I hope that words like 'Korean Collar' and 'Hanbok Sleeve' will one day become a household term. Hanbok contains Korea image. And its shape is formed depending on how Koreans have been treating all sorts of objects or things for many years. If my study can identify and express the unique Korean way of pattern and considering clothes, which is clearly different from those of China and Japan, I will be able to establish a concept of 'Korean style', that people of the world could come to recognize.

In order to investigate the mechanism of the formation of clothing microclimate with different blouse designs and materials, physiological and subjective sensational changes were measured. Experimental clothing were four types of blouse made of $100\%$ cotton, $100\%$ regular polyes­ter, and $100\%$ hygroscopic polyester. Four types of box style blouse were with stand collar and long sleeve, with stand collar and sleeveless, with long sleeve and collarless, and sleeveless and collarless. Five healthy female were chosen as subjects. Experiments were carried out in the environ­mental chamber controlled at $28{\pm}1^{\circ}C$ , $70{\pm}5\%$ RH. and still-air condition for SO min. The skin temperature (9 spots), oral temperature, humidity inside chest, and subjective sensations were measured. Obtained results are: I) Material which is capable of absorbing sweat effectively and transfering moisture rapidly made a comfortable feeling, because cloth­ing humidity is increasing slowly at this material. 2) During exercise period, covered arms have more influenced on thermal comfort than a covered neck.

The purpose of this study is to investigate men's coat of Jikryeongkoim style that were excavated from the tombs of the Yeosan Song family. Findings of the study can be summarized as follows. Except Dapho, all of the above mentioned coat were usually worn in the late 15th and late 16th centuries. Jikryeong and Cheolik were often worn in both of the centuries. But Aekjureum was often worn in the late 15th century and Jikryeong with no side hem and Jikryeong of Dopo style, in the late 16th century. Generally, the men's coat of Jikryeongkoim style had a short fore part and a long rear part, doubled kalgit of banmokpan style and a narrow sleeve in the late 15th century, while fore and rear parts of the same length, kalgit of ordinary style and the sleeve of bean chaff shape in the late 16th century. In both of the centuries, the coat had the outer Seop that was doubled and used short, narrow coat strings to be adjusted. Samgakmu was used to Jikryeong with no side hem and Aekjureum. Out of the coat, those which were lined or padded or quilted with cotten used Samgakmu, but those which were unlined didn't. To adjust the coat, usually, a pair of short, narrow coat strings was used. The coat had the coat strings directly stitched on them or indirectly connected to them by means of the coat string hanger.
