This study was performed to investigate the effect of kangaroo care on body weight, physiological responses and behavioral states in premature infants. The subjects were 32 premature infants, fifteen for the kangaroo care group and seventeen for the control group, who hospitalized in a neonatal intensive care unit at a university-affiliated hospital. The kangaroo care was applied 8 times during the twenty five days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a premature infant wearing a diaper and a hat is placed on its mother's chest. As for the measures, body weight was measured everyday. The levels of epinephrine, norepinephrine and 17-OHCS were measured twice, before beginning the first intervention and after finishing the last intervention. While each session of the care is undergoing, such physiological responses were measured periodically as heart rate, respiration rate, oxygen saturation, core temperature and skin temperature. The results were as follows : 1. The weight gain was significantly greater in the kangaroo care group than that in the control group during the period of performing the kangaroo care. 2. No significant difference was revealed between the two groups in heart rate, respiration rate, oxygen saturation and core temperature. The kangaroo care group also showed significant increases in the skin temperature. 3. The differences in the levels of epinephrine, norepinephrine and 17-OHCS were not significant between the kangaroo care and the control groups. The level of norepinephrine in the two groups was significantly increased over time. 4. Sleep pattern changed significantly in the kangaroo group from a very restless sleep to a very quiet sleep. These results suggest that kangaroo care is an effective nursing intervention for premature infants in gaining weight, achieving stable physiological responses and facilitating a quiet sleep.

The present paper mainly cocerns, in social aspect of the cultural change, with how cholik was introduced and accepted in $Kory\v{o}$ dynasty. It was through cultural transmission in political relations with Won dynasty that $ch\v{o}$ lik was first listed on our own costume system in later $Kory\v{o}$ dynasty. The acceptance by $Kory\v{o}$ society can be interpreted as the twofold effects; positively, it enriched our costume system and, negatively, it brought about various conflicts, which in turn caused some unwelcome reactions. Once it had permeated into $Kory\v{o}$ culture. it could not avoid being changed by social conditions. The changing process can be defined as the dual cycles of fashion. The first one startd at mid peroid of $Kory\v{o}$ when King $Chung-ry\v{o}$l provided a law to wear the $W\v{o}n$ costume and. ended at larter $Kory\v{o}$ of King Kong-min's reign. The second cycle rose in the period between King Sejong's reign and late $Chos\v{o}n$. Each of the two cycles appeared to have its own characteristics; 1. The first cycle. 1) In spite of the long period of a century, the cycle was very abrupt both in development and decline. 2) The abrupt pattern of the cycle can be attributed to the nation-wide law provided by the ruler. 2. The second cycle. 1) Compared with the first cycle, the curve was rather slow. 2) The fashion originated from the hyperimitation of the government officials, since the costume was the royal gift by Chinese Emperor. 3) The main cause of the development of the fastion was the wars, rather than the public preference. 4) The main cause of the decline of the fashion was that it could no more differentiate the social status, that the wearer was laughed at by the Chinese, and that the long period of wearing the same dress stimulated the fashion psychology. 5) The increasing size of the costume rather decreased the very function of the costume.

In this study, a chitosan based coating method was developed and applied on the shoe lining leather surface for evaluating its inhibition to bacterial and fungal attacks. At first, chitosan was prepared from raw prawn shells and then the prepared chitosan solution was applied onto the leather surface. Secondly, the characterization of the prepared chitosan and chitosan treated leather was performed by solubility test, ATR-FTIR, XRD pattern, SEM and TGA. Evaluation of antimicrobial efficacy of chitosan was assessed against two gram positive, two gram negative bacteria and a reputed fungi by agar diffusion test. The results of this study demonstrated that chitosan took place in both the surface of collagen fibres and inside the collagen matrix of crust leather. The chitosan showed strong antimicrobial activities against all the tested microorganisms and the inhibition increased with increasing percentage of chitosan. Therefore, the prepared chitosan in this study can be an environment friendly biocide, which functions simultaneously against different spoilage bacteria and fungi on the finished leather surface. Thus by using the prepared chitosan in shoe lining leather, the possibility of microbial attack during shoe wearing can be minimized which is one of the important hygienic requirements of footwear.

The purpose of this study was to develop the construction process of orthopedic compression garments (OCG) for balancing of the left and right lumbar muscle power and strength to prevent low back pain. One male subject having low back pain was involved for investigating of the lumbar muscle power. EMG (Telemyo DTS2, Noraxon, U.S.A) was measured with/ without 3 types of waist assistant belt around the waist area of the subject. Based on the electromyogram value of left and right body, OCG were constructed as follows. Firstly, stretchable t-shirts type with supportive waist belt was selected for the convenience of wearing and laundering the OCG. The design lines of the front and back waist parts were created depending on the anatomy of the torso. Secondly, 3D pattern was developed using 3D Clo, RapidForm XOR, 2C-AN, and Yuka CAD program to increase the fit of the OCG. Finally, stretchable power-net was layered as linings in two ways, a single lining and double layered linings, and evaluated measuring lumbar muscle EMG by five subjects with low back pain. As the results, they were effective to balance the left and right lumbar muscle power and strength. Also the OCG with the double layered power-net lining was superior to the one layered lining in terms of fit and comfort.

The purpose of this study was to suggest torso patterns that fit the three main body shapes of elderly obese women. To reduce time, costs, and also the trial and error needed to make patterns, the CLO program for 3D test wear was employed. Three virtual models for aged obese women were use, with the YUKA system used to produce torso patterns. 3D simulation of test wear and corrections was done to design optimal torso patterns. The results were as follows: First, for the three models of obese women's body shapes as realized by CLO 3D, Type 1 is lower-body obesity shapes, Type 2 is abdominal obesity shapes, and Type 3 is whole-body obesity shapes. Second, to design the study patterns, actual measurement values, back waist length and waist to hip length, were used. The armhole depth (B/4-1.5), front interscye (B/6+2.3), front neck width (B/12-0.5), front neck depth (B/12+0.5), front waist measurement (W/4+ 1.5+D), front hip measurement (H/4+2+0.5), and back hip measurement (H/4+3-0.5) were calculated using formulas. Third, according to the results of test-wearing the study patterns, reduced front neck width and depth improved the neck fit and reduced armhole depth bettered loose or plunging armhole girth and also reduced the sagging of bust c.. Also, tight sidesfrom aprotruded waist and abdomen improved with the increase of surpluses in the back waist and also back and front hip c. The exterior was enhanced by displacement of back and front darts, which distributed surpluses better.

The purpose of this study is to develop comfortable patient gown for spinal surgery patients. The results of the survey confirmed inconveniences and problems with the current gown, and a new gown style was recommended. The recommended changes addressed design, pattern, and materials. The final experimental design for the top of the new patient gown is a wrap style that moves the center opening of the gown to the side and enables patients to control the length of the sleeves by attaching two snaps. The cutting line is aligned with the back brace location, and the issue of repeated bunching of the gown material by the brace was solved by substituting 100% knitted structure fiber. The sleeve length can be adjusted with snaps on the sleeve cap and hem. When lifting up the gown for treatment on specific areas of the body, doctors open the edge of the right side of the gown in order to lift up the top. The bottom of the new patient gown was made from 100% cotton knitted structure fiber, and it enables patients to control the length of pants by attaching two snaps on the side. The results of an on-site dressing suitability evaluation and a flexibility evaluation with respect to dressing/undressing indicated that the new patient gown was much better received than the existing gowns (A and B). Our hypothesis regarding new patient gowns was supported in both the fit and design categories.

This paper is intended to grasp the characteristics of many bodices patterns which have been shown so far. The way is by selecting four characteristic kinds of patterns, making blouses offer the patterns and measuring ease. In measuring the degree of ease, $Scheff\`{e}'s$ paired comparison is made use of. In analysis, variation ratio has come out of analysis of variance, and significance is tested by producing estimated values between patterns. The Result is summed up as follows. 1. After wearing blouses made ofter different basic patterns and measuring ease, the analysis of variance is made about the sensory value of ease. The result is as follows. 1) In the ease of different patterns, all the areas are significant at the level of $1\%$ , regard- less of movements. 2) Under the influence of movements, the back area of arm hole is significant at the level of $5\%$ in narrow movements, and the front and the back area of arm hole are each significant at the level of $1\%$ in wide movements. 3) In the interaction of patterns and movements, bust and the under area of arm hole are each significant at the level of $1\%$ in narrow movements, and bust is significant at the level of $1\%$ in wide movements. 2. When comparing estimated values between patterns, the value of c is the largest and in the order of b,4, a. And in the other movements, the order changes into c,d, b and a. Thus the ease of blouses is different according to patterns. The reason for this is that the amount of ease of bust, the amount and location of darts, and sleeve cap height have complicate influences on the ease of blouses. Both sleeve cap height and the depth of arm hole have influences on the ease of sleeve. Consequently, in making clothes, it would be better to select and use proper patterns which go with the purposes and desings of clothes rather than to apply one pattern to various clothes.

Skirts hold an important position in dress culture among various dress forms, being worn by more than half of mu. In this study, Chima is defined as garment for lower part of the body without crotch sewing, contrasting with trousers. The authors classify and compare the formation of the skirts of minority races in Yunnan area, based on Korean Chima, understanding the forms of skirts and examining the composition, color, pattern and material. For the study, the authors investigated 57 pieces of skirts among 341 pieces of minority races dresses from Yunn Nationality Museum collection exhibited at Korea Folk Village in May 2003, and referred to customs materials and photos in various literatures. Skirts in Yunnan area are divided into 6 areas, that is, seamless one-piece skirt area, wrapskirt area and mixed type skirt area. Skirt formation factors from the effect of environment such as climate, lifestyle and means of production were studied, and characteristics, differences and similarities were reviewed. Figure of skirts are studied by compostion, color, material, and technique. By composition, they can be classified based on the similarity to Hanbok (traditional Korean dress). By color, worshipped color and preferred color vary by races and by area. Materials vary in kinds and thickness by area with various climate. By technique, national characteristic patterns are inherited through national traditional dyeing and embroidery. It is not easy to conclude based on single item of skirt, but we suggest that national dresses have been settled through the mutual supplements between the effect of social and cultural exchange such as historical inheritance, geological environment, religion and production activity and the various forms of skirts from changes in shape, color, material and wearing form of dresses.

This study analyzed the fabric and product size of the burn patient's custom compression garment and measured the pressure applied by the garment to assess whether proper pressure is being delivered for treatment. The test clothes were presented to the market by body size and commissioned with the same design. The subjects selected four people close to the average body size of men in their 20s determined by 7th Size Korea. The experiment was conducted by wearing a compression suit, performing activities and measuring changes in the pressure of the garment according to changes in posture. The fabric used for the compressive clothing was not ruptured even at 216 kPa, the elasticity recovery rate was measured between 80.5 and 94.5%. The product dimensions of the experimental clothing varied by up to 8cm from brand to brand, requiring the standardization of compression clothing. The experiment showed that four types of compression suit varied in pressure, and the pressure range, excluding the gastric arm (17.9mmHg), was between 2.5-14.1mmHg, which failed to meet the level of pressurization for treatment purposes. The clothing pressure in the chest area dropped when performing movements rather than standing still. This was interpreted to be a result of reduced the adhesion of the compression suit during operation. The peak pressure (31.68mmHg) and the lowest pressure (2.2mmHg) was noted in the scapula, indicating that no pressure was being transmitted on the vertebrae. The pressure of the garment on the right shoulder blade was elevated in a supine position. Because much time is spent laying down, it is necessary for the pattern design to accommodate for the increased clothing pressure on the shoulder blades. Standardization of the level of pressurization for burn patient's custom-made pressure suits for each stage of treatment is urgently required.

This study provides a size specification and ease for the development of pants for working clothes in the construction industry according to season. We collected and measured the size specification of 4 types of Spring/Fall pants, 4 types of winter brushed bonding pants, and 4 types of winter padded pants. Subjective comfort evaluation and analysis of ease sensation were performed for all products on 12 subjects. The average size specifications for the pants according to seasons were as follows. Spring/Fall pants had 74.0/80.0cm waist size (relaxed/maximum stretched) and 104.0cm hip size. Winter brushed bonding pants had 76.0/83.4cm for waist size and 106.0cm for hip size. Winter padded pants had 71.5/84.0cm for waist size and 112.8cm for hip size. When designing a pattern by comparing product size specification and subject body size, the recommended ease is 0.2/7.2cm for waist size (relaxed, maximum stretched) and 13.6cm for hip size for Spring/Fall pants, and 0.2/6.2cm for waist size and 11.6cm for hip size of winter brushed bonding pants, and -5.3/7.2cm for waist size and 19.4cm for the hip size of winter padded pants.
