In this study, structural stability of large diameter high density polyethylene (HDPE) pipe during installation was numerically investigated in order to investigate the effect of concrete collar dimension, water depth and tension (pulling force). From the numerical simulation results, the total stress of HDPE pipe with designed concrete collar was within 2.5%, so the total weight of concrete collar for sinking of HDPE is important rather than concrete collar dimension. Furthermore, the tension area for possible installation is decreased as the air filling rate is increased. Therefore, it is important to calculate the reasonable tension range before actual installation for safe installation of HDPE pipe.

This paper presents the experimental study of nine pieces of reinforced concrete (RC) short columns. RC short columns were tested with cyclic loading with displacement control under the influence of constant axial load with load index of 0.2. Three columns within the tested nine columns are reference columns which have the details of the reinforcement given in the modern regulations and six of them are 150 mm and 100 mm externally collared columns. In addition to the parameter of the collar spacing, aspect ratio (as=2-1.5-1) is also considered as a parameter. The data obtained from experimental results have shown that externally collar contributes significantly to increasing the shear resistance of RC short columns and limiting the shear dominant behavior. It has been observed that the effectiveness of the externally collar increases with the decrease of the aspect ratio.

This study is about reproduction of Yoseon-Cheobli excavated from Byun-su tomb in earlier Joseon Dynasty. There are three Yoseon-Cheobli in Byun-su tomb. The producing process is made in concrete by suggesting the process of producing clothing. Based on the Annals of the Joseon Dynasty, the most frequently recorded one, was reproduced by dying fabric with safflower and indigo plants. Through the research about their specific size, sewing method and construction, it have been produced in the following. First, the revealing that collar to be half-square and to compose the line in the center of collar. The width of the collar is 11.6 12.1cm. Second, the 21~22 pairs of waist lines that are 13~14cm in width fixed at intervals of 0.3cm. The method of making waist lines is twisting either fabrics or silk threads. Third, fine gathering around the part of the waist of skirt, and the size of fold surface is 0.2cm. Sewing method needs running stitch and backstitch. As the result of producing the cloth, it became to possess more ornamental features after transformation suitable to the new environment while the same remained functional features for everyday life such as a dressing shape, length of the bodice and curvy completion line of a collar strip.

This study intends to provide sources which enable students to satisfy uniform design as I surveyed preferable uniform design and degree of satisfaction of uniform design to students. The subjects were gathered into 91 middle-high schools and surveys were done among 400 school girls. The results are as follows; 1)The survey of uniform which students wear. For jacket, tailored collar which is single breasted is most common and for blouse, puff sleeve, soutein collar, shirt collar is common. For skirt, lastly, they usually wear side pleats skirt. 2) Thoughts of uniform students preferred uniform to casual. The merit of wearing uniform can represent themselves as the ‘students’on the other hand, the demerit is shown that uniform is inconvenient enough to move. 3)Preference of uniform design. Students prefer tailored jacket, shirt blouse, flare skirt. Basing on these results above, I’d like to suggest something about uniform. The demerit of wearing uniform lies in inconvenience. It would weaken the degree of satisfaction of uniform and have a negative influence on students in physical and mental side. So we have to find out the concrete problems, at the same time, develop measurable study which fit for body. Adolescence is period of developing and establishing self. So they really need rather creative educational atmosphere than stereo typed-control. Reflecting this opinion, Clothing habits can play an important role and in future it is desirable to have students wear not uniform but casual.

This study is the design research for the practical use of Casual Hanbok. The conclusion of basic research for Casual Hanbok design reads as follows. Today's college women are fairly positive to the practical use of Casual Hanbok. Especially, they are strongly interested in the new design and have the active intention to wear it on actually. The concrete design of every parts of Casual Hanbok which is wanted by college women is as follows. Firstly, college women like well matched two-piece dress style in colors. And they want to decide the coloration independently than to follow the traditional coloration passively. Secondly, according to the design of jacket, sometimes they like the presence of a collar, a collar strip, a gore etc. and at other times they like absence of them. Thirdly, the side line of jacket they like and the seam line of sleeve they like is smoothly curved one and the adjusting means they like is a fancy button. Fourthly, the length of jacket they like reaches to their waist and the width of an armhole they like must be convenient for moving of arm. Fifthly, one out of two college women likes mixed spinning fabrics as material for jacket, skirt, pants. In the other hand, one out of five college women likes cotton. Sixthly, the skirt style they like is A ­line one having from two to four gathers on the waist and the length of skirt they like reaches to their ankle or calf of the leg. Seventhly, the pants style they like is the western style but the hem line of pants is the korean traditional pants style.

Due to the high compressive and tensile strength of ultra-high performance concrete (UHPC), UHPC used in steel concrete composite structures provided thinner concrete layer compared to ordinary concrete. This leaded to the headed stud shear connectors embedded in UHPC had a low aspect ratio. In order to systematic investigate the effect of headed stud with low aspect ratio on the structural behaviors of steel UHPC composite structure s this paper firstly carried out a test program consisted of twelve push out specimens. The effects of stud height, aspect ratio and reinforcement bars in UHPC on the structural behaviors of headed studs were investigated. The push out test results shows that the increasing of stud height did not obviously influence the structural behaviors of headed studs and the aspect ratio of 2.16 was proved enough to take full advantage of the headed stud strength. Based on the test results, the equation considering the contribution of weld collar was modified to predict the shear strength of headed stud embedded in UHPC. The modified equation could accurately predict the shear strength of headed stud by comparing with the experimental results. On the basis of push out test results, bending tests consisted of three steel UHPC composite slabs were conducted to investigate the effect of shear connection degree on the structural behaviors of composite slabs. The bending test results revealed that the shear connection degree had a significantly influence on the failure modes and ultimate resistance of composite slabs and composite slab with connection degree of 96% in s hear span exhibited a ductile failure accompanied by the tensile yield of steel plate and crushing of UHPC. Finally, analytical model based on the failure mode of composite slabs was proposed to predict the ultimate resistance of steel UHPC composite slabs with different shear connection degrees at the interface.

This study was aimed at investigating the satisfaction in relation to clothing design and size-fit for nurse uniform in Korea. The subjects were 986 female nurses working in 12 hospitals selected by convenience sampling. The data were collected by questionnaires. Using SPSS package, frequency, percentage, t-test, ANOVA and SNK test were conducted. The results were divided into 2 categories as fellows; 1) Results of the satisfaction with the size-fit and size system of the nurse uniforms : Nurses satisfied at the individual size-fit system than ready-made size system. There was a considerable difference of the satisfaction with the size-fit depending on age and clinical career. And more than half of nurses were needed the concrete and precise size system. 2) Results of the actual design condition and clothing satisfaction : Nurses wore two-piece pants suits more than classical designed one-piece style. The princess-line, convertible collar and yoke design were preferred for nurse uniform with the high satisfaction. 41.6 percent of respondents used the cap obligatory and the white color and a patterned textile were generally used. The used fabrics were only polyester and cotton/polyester mixed spinning.

The purpose of this study is to present de-sign development and constructive method on man's Hanbok which can be put on daily-life clothing through supplementing the incon-venience of HanBok and to make men put on daily-life-HanBok through making the HanBok ready-made clothing which has lower-price. The concrete test and its process on devel-oped design are below. (1) In present there are five uncomfortable point waist closing baji's slitting and daenim (2) Developed the first design concentrating on uncomfortable parts with Korean costume-pattern (3) to supplement sleeve armhole and waist closing which are pointed out as the incon-venience at first design development did the second design development. The results through research and process are below. (1) In the functional test of testing clothing a testee is satisfied with jegory's closing at 87. 5% with pocket at 100% and with baji's front closing and daenim (2) The opinion of an observer on daily-life Hanbok is an affirmative response as following turns: traditional aspect practical use and aesthetic aspect. (3) Analyzing the relations between the characters of daily-life hanbok and the popu-lation density variables results are the popu-lation density variable results are followed below. Man has highe points than woman on asthetic and economical aspect. In preferences as educational levels more-educated person has an affirmative response on keeping traditions. In jobs students and white-collar people have affirmative responses on traditions. (4) What one wants to wear the most is the fourth Hanbok(mixing western and Korean costume style with Korean costume fabrics) and daily-life Hanbok with western costume fabrics has 51.8% preferences of responsers. With those results man's daily-life HanBok made through the first and the second design development lessens the inconvenience of Hanbok with some degrees. Also if daily-life Hanbok design continue to be developed through using Korean costume fabrics and western costume fabrics people can easily by functional and practical daily-life Hanbok because it can be massproduced.

In western clothing, woman's body was port-rayed sexually as the distinction of sex was appeared, and the parts of body contain some kind of symbol of sex. Woman's body was diversly accentuated according to the divers ideal beauty concepts pursuits in the different periods. Today, in a Post-industrial Society whose social structure is very divers and complicated, the interpretation of woman's body reveals so various as the complex social structure. The purpose of this study is to comprehend the various interpretations of woman's body in the contemporary clothing. The concrete purposes of this study is as follows. First, this study is to define the concept of natural body and built body by differentiating the parts of body and searching for the sexual symbols accentuated in the western clothing. Second this study aims to review, the histori-cal process of prejudged distinction of sex in the western clothing, and to analyse the con-temporary sociocultural which forced to change this prejudged distinction of sex. Third, on the bases of this analses, this study also aims to present various interpretation on divers aspects of woman's body portrayed in the contemporary clothing. The interpretation of woman's body in the contemporary clothing were as follow. First, it is a body interpreted as a natural and neutral body which is based not so much on prejudged division of sex as on the expression of the body structure. And, it is a decomposed and recomposed body which is based on plastic principles. This body is portrayed by a layer-ing and wrapping which interrogated such traditional symbols of western clothing as collar, sleeve or trousers, skirt, etc. Second, it is a sexually symbolized body. This body is display-ed by exposure or sexual accentuation in the clothing. To conclude, a body interpreted in the contemporary clothing is no more a body accentuated by division of sex, but a body which per-mits indefinite hypotheses and interpretations under synthetic imagination.
