The purpose of this study is to analyze the patterns of commercial Cheollik dresses by size analysis and wearing evaluation. Six kinds of commercial Cheollik dress patterns distributed on the market were selected and classified into two types group, A type group(A-1, A-2, A-3) consisting of flat type sleeve pattern and B type group(B-1, B-2, B-3) consisting of three-dimensional type sleeve pattern depending on the sleeve type. The size of the Cheollik dress pattern was analyzed, and wearing evaluations of the appearance, movability were carried out. Cheollik dress pattern was made in various size and many patterns were produced in the form of omission of components such as seop. It should be based on the understanding of the form and composition of the traditional Cheollik for pattern development. As a result of the wearing evaluation, A-2 showed the highest evaluation in the appearance and movability evaluations in type A. B-2 was the highest evaluation in appearance evaluation in type B. But in the evaluation of the movability, B-2 received the lowest evaluation because of little allowance. Therefore, the allowance in clothes should be considered enough for the movability. The result of this study can be provided as a basic data for the development of Cheollik dress pattern reflecting modern trend and the traditional beauty.

In Korea Gas Corporation, as one of the pipeline repairing methods, damaged pipelines are sometimes treated with a temporally employment of split sleeve. On conducting the repair process, circumferential fillet and longitudinal groove welding usually must be included. For the case of groove welding, a considerable amount of R&D have been carried out related to property changes, while few study on the property change in fillet welding has been conducted. In this paper, so as to confirm the specification of fillet welding in terms of safety and reliability, properties changed by fillet welding were investigated for two welding processes. Qualifying tests such as reviewing macrostructure and nick-break tests were performed according to API 1104 and ASME section IX. In addition, tensile properties and hardness were evaluated according to KS B0841 and BS 4515. The fillet weld prepared by the qualified procedure showed melting depth of 0.8∼1.3mm and heat affected zone of 2.8∼3.4mm length. No crack and lack of penetration were observed. And the results of hardness and nick-break tests satisfied code requirements. The area crossed by fillet and groove welding line was found to have minimal tensile strength.

Air springs are prevalently used as suspension in train. However, air springs are seldom used in automobiles where they improve stability and comfort by enhancing the impact-relief, breaking, and cornering performance. Thus, this study proposed a new method to analyze air springs and obtained some reliable design parameter which can be utilized in vehicle suspension system in contrast to conventional method. Among air spring types of suspension, this study focused on sleeve type of air spring as an analysis model since it has potential for ameliorating the quality of automobiles, specifically in its stability and comfort improvement by decreasing the shock through rubber sleeve. As a methodology, this study used MARC, as a nonlinear finite element analysis program, in order to find out maximum stress and maximum strain depending on reinforcement cord's angle variation in sleeves. The properties were found through uniaxial tension and pure shear test, and they were developed using Ogden Foam which is an input program of MARC. As a result, the internal maximum stresses and deformation according to the changes of cord angle are obtained. Also, the results showed that the Young's modulus becomes smaller, then maximum stresses decrease. It is believed that these studies can be contributed in automobile suspension system.

Shirts which have been a inner-wear in men's suit in the past, are being changed into an item that 20's men utilize to their individuality. Dress shirts have gotten out of its shape, becoming tight and slim with activity and fashion trend. In this study, two patterns of fitted dress shirts in a clothing construction text book were compared with the pattern of an apparel company with regard to the size tolerance and appearance silhouette; this comparison was performed through a fitting test and an appearance evaluation. According to the study, size tolerance of chest girth and waist girth were about 6~8cm and 10~18cm, respectively. Neck girth of the collar was tight in both the fitting test and appearance evaluation. Thus, the measurement value of the neck base girth had to be used for the collar pattern making. Moreover, approximately 35cm is a moderate size for the width on the upper arm in sleeve. Therefor the factors such as size tolerance of waist girth, height of sleeve cap, slim sleeve width and measurement value of neck base girth are being considered for the pattern making of fitted dress shirts.

This study were to grasp the present situation of the pet wear market and the problem of pet wear, and to develop the pet wear pattern which agrees well to dog's shape and movements. We carried out survey research to analyze the actual pet wear market condition for a dog-lover, and movement analysis and sensory test to develop a pattern for Maltese which was the favorite dog among Korean. For data analysis, ANOVA with duncan test, T-test were conducted using SPSS statistic program(ver. 10.0). The results are as follows: 1. The results of the survey research, 75% of dog-lover had a pet wear and favorite was T-shirts. The problems of wearing T-shirts were 'too tight seam sleeve and bodice(front legs hole)', 'the clothes easily hang down' and 'easily taken off due to large neck size'. 2. The ease amount of the developed pattern was given according to the results of dog's shape and movement analysis, and the results of sensory test, there is a significant difference in the following items: depth of front neck line, front chest${\to}$abdomen curve, ease amount of sleeve, comfort level of leg parts. 3. The size of each parts of the developed pattern in this study were as follows : neck girth 27.0cm, body girth 40.0cm, back length 26.0cm, front leg girth 23.0cm, sleeve length 20.7cm, sleeve width 14.4cm. But, there exists some limits to generalize these results since dog's body size and shapes are various according to dog species. Therefore, further studies are needed to develop each pet wear pattern for each dog species.

This research aimed to identify the characteristics of outdoor apparel market for new seniors. To achieve this goal, influence of new seniors' lifestyle and apparel purchase criteria of design preferences of outdoor apparel products were investigated. An online-survey was conducted targeting fifties who have bought outdoor apparel within one year. The collected data were carried out for factor analysis, independent sample T-test, and regression analysis by using SPSS 22.0. Results showed that new seniors' lifestyles were composed of appearance-orientation, well-being diet, well-being exercise, self-development, and challenge-orientation. Purchase criteria of outdoor apparels were factored out as practical, aesthetic, and social. Appearance -orientation and self-development affect aesthetic and social factors. Well-being diet influences all factors of purchase criteria. Challenge -orientation has effect only on social factor. Women favored round-and V-neckline more than men did as well as preferred half and 3/4 long for sleeve. Customers who value practical purchase criteria preferred half-sleeve, zipper, and button-closure designs. In contrast, customers who have aesthetic purchase criteria like round/V-neckline and cap sleeve. Social factor affected high neckline and vivid-tone color preference significantly. As outdoor design for new senior it is critical to introduce differentiation of outdoor brand with various designs combining functionalities of outdoor activities and style looking young and dandy, which is highlighted as trendy and casual, over current outdoor apparels' unified design.

In May 1987, 11 clay icons and other stone products were excavated in an abandoned ancient tomb which was located in 541-1 Hwangsung-dong, Kyungju. 6 clay figures of them were depicted realistically man's features and postures, costume at that time that they gave a lot of significance to the fields of Korean Costume's Academic Society. The main purpose of this thesis is to study the background of costume history when it was made and its formal characteristics with the study of those 6 clay figures. Shilla accepted the customs and attires of Sui and T'ang by means of frequent in coming and out going Chinese envoy as well as Shilla's envoy, monks, hostages, and students in China. From that period, the diversity of Shilla's costume began to develop by introducing Tang's style into Shilla's costume. Crested hat of men's clothing of the clay figures in Hwangsung- Dong is Bokdu Men's figure II wore Bokdu which Hugak is attached to Byunhyung. The garment is a Po and it is a tight sleeve and silhouette's Banryungpo. The horizontal line of hemline of men's figure 1 can be presumed by expression of Ran though it is not as accurate as the clay figues in Yongg-ang-Dong. As for torso part 1, it can not be known the style of the crested hat because the head part was damaged, but it were shoes, belt and common sleeve, Banryungpo on tight sleeve shirt and tight trouser. The hair style of the women's clothing in Hwangsung-dong clay figure is Bukkye peculiar to Korea. The costume was slim silhouette that people wore tight sleeve and short blouse and long skirt and belted on their bosom which dresses style was in vogue from late Sui dynasty to the early years of the Tang period. The silh ouette of slim silhouette's high waist which can be seen in the women's dresses is mainly worn by Chinese and affected Shilla's costume. Therefore the dresses style of the clay figures in Hwagsung-Dong, it is considered it is a dresses style of tight sleeves and slim silhouette together with the adaptation and abolition of foreign elements on the basis of Shilla's own elements like Bukkye hair style and tight sleeve and silhouette. The style of Yonggang-Dong's clay figures expresses spherical gei and common sleeve, loose silhouette of flourishing Tang's costumes planly whereas the style of Hwangsung-Dong's clay costumes expresses refined spirit of the Shilla(Shillaism) though it is extremly simple.
