Physical measurements of 181 Korean elderly women, aged 60 through 79, living in the Seoul area, were taken in 1981 in order to analyze their body types and to study clothing construction according to their body types. The study was composed of 117 items in all; 35 items in measurements, 1 items in Rohrer index, 68 items in physical index to stature and bust girth, and 14 items in proportion, Coefficients of correlation among body dimensions were used. The results from this analysis are as follows: 1) The most significant changes in body dimensions in advanced age were the decrease of bust height and the increase of both abdomen girth and waist girth. 2) Distinct physical changes did not appear until advanced senescence(70~79 years of age). 3) In the three somatotype groups(thin, average, and plump) categorized by their Rohrer index, the dimensions that remained unchanged in senescence were back waist length and front waist length ; the dimensions that varied most significantly in senescence were the waist measurements. 4) As a result of the analysis of coefficients of correlation among the body dimensions of the 3 figure groups categorized by the Rohrer index, the fundamental dimensions for establishing the size of ready-to-wear garments of elderly women were the stature, bust girth and center back length in upper garments. 5) The result of the analysis of physical index and proportion of the 3 figure groups showed that the more plump a figure might be, the ratio of depth to width measurements increased; the back waist height was higher and trunk enlarged. 6) The 9 figure categorized by their Rohrer index and stature showed that the percentage of women in the category of“normal figure”decreased more in advanced senescence than during early senescence. 7) An analysis of variation of the 9 figure groups, the stature and other items for a short and thin figure were the smallest, and for a tall and plump figure, the largest.

Purpose : This study was conducted to understand the health status and health behaviors of preschoolers to provide baseline data for developing health promotion programs. Method 'Parents of children attending day-care centers and guardians of preschoolers were recruited for the study. Data were collected from June to August2002 using a structured questionnaire. Result . Among 754 preschoolers, 17,3% were overweight, while 18.2% were underweight, while 15.9% and 23.2% were overweight and underweight respectively, among 85 children living with guardians. The most frequent infectious diseases that children have had previously were hand-foot-mouth disease, chicken pox, and measles. Current health conditions that children have frequently are respiratory disease and atopic dermatitis for bother groups. Only 54%-61% brush their teeth everyday at bedtime, 49%-54% wash their hands every time after returning home, 4.5%-8.8%wear bicycle helmets, 9,3%-11.1% use a child car seat, and 3.5%-8.1% eat fruits and vegetables five times a day, Children living with guardians were less likely toper form positive health behaviors compared with children in day-care centers. Conclusion 'Based on the study results, health professionals could plan and develop health promotion programs to change unhealthy behaviors of preschoolers targeting high-risk groups.

Low frequency heavy-weight impact noise is the most irritating noise in Korean high-rise reinforced concrete apartment buildings. This low frequency noise is generated by foot traffic due to the fact that Koreans do not wear shoes at home. The transmission of the noise is facilitated by a load bearing wall structural system without beams and columns which is used in these buildings. In order to control low frequency heavy-weight impact noise, floating floors using isolation materials such as glass-wool mat and poly-urethane mat are used. However, it was difficult to control low frequency heavy-weight impact sound using isolation material. In this study, reinforcement of concrete slab using beams and plate was conducted. Using the FEM analysis, the effect of concrete slab reinforcement using FRP(fiber-glass reinforced plastic) on the bang machine impact vibration acceleration level and sound were conducted at the standard floor impact sound test building. The $3{\sim}4dB$ floor impact vibration acceleration level and impact sound pressure level were reduced and the natural frequency of slabs were changed.

Refrigeration and air-conditioning compressors used in home appliances, including refrigerators and air conditioners, are typically hermetic-type reciprocating compressors. Because the shell is sealed by welding, it should be designed to have a semi-permanent life. The energy consumption of a hermetic-type reciprocating compressor is low, but because it operates continuously to maintain a constant temperature inside the refrigerator, it has a certain base load. In this type of compressor, the driving motor operates at a high speed (about 3,000 - 3,600 rpm), which causes valve damage, friction, wear, and high-frequency noise. Many studies have been conducted to solve these problems. To enhance the reliability and efficiency of the reciprocating compressor, the design conditions and operating environment of journal bearings should be considered. Dynamic behavior analysis should be carried out in terms of the discharge pressure. The results showed that the load (discharge pressure) increases in the forward lookup zone and decreases in the backward lookup zone. When the revolution speed is increased, the maximum load decreases in the region where the maximum load operates.

The goal of this study is to investigate the current conditions of apparels for the handicapped, identify the problems and recommend what are appropriate and functional apparels for the handicapped. The research method was to statistically process a survey on 200 handicapped by frequency analysis and cross tabulations. The study results are as follows. First, the degree of discomfort in daily activities was shown during toilet use and eating. Among clothes categories owned by the handicapped, most discomfort was felt in the order of everyday clothes, workout clothes, underwear, athletic shoes and working clothes. Second, children's clothing was most commonly preferred clothing style by handicap for the dwarfism. Comfortable clothes was preferred and relaxed, decent, and unique styles were preferred in the order. Soft feeling texture and absorbency was considered important as preferred clothing material. Third, sizes and designs were improvements wanted by the handicapped in apparel in the order. In addition, they wanted to wear apparel sensitive to the fashion just like the non-handicapped without showing the handicapped parts. There is a necessity for the government or municipalitiesto establish and run protected workplaces or independent workplaces for those who have studied apparel. The field is thought to require continuous and numerous follow-up studies such as researches on different physiques, standardization of apparel, segmentation of sizes and methods of producing custom apparel by function and handicap.

Middle and High school students are highly interested in appearance and clothing and they use it as a method of expressing their personality and freedom. We examined clothing attitudes and school uniform attitude of the students and analyzed relationship between them by the survey of 446 middle and high school students living in Seoul. First, High school students have more positive attitudes towards school uniform than middle school students have. High school students prefer school uniform and wear more frequently than middle school students do. Second, the group of economic efficiency and individuality have more positive attitudes and prefer the school uniform than group of practicality, fashion and conformity have. The group of fashion and economic efficiency show the preference of famous brand. Based on these results, we understand the attitudes of middle and high school student towards school uniform with reference to the clothing attitudes. Therefore, we need to accept demand of students in producing school uniform.

In this study, we have focused on various types of costumes for traditional Ganggangsullae and daily dance Ganggangsullae. To analyze their costumes, spot photographs of Ganggangsullae contests from 2011 and 2013 were collected from the Department of Culture and Tourism, Jindo County Office and the Jeonnam Information & Culture Industry Promotion Agency. Costumes were analyzed by categorising them as type, shape and color. Traditional Ganggangsullae costumes are two types: traditional hanbok and saenghwal hanbok. Traditional hanbok design dates back to the late Joseon dynasty and saenghwal hanbok design to the middle Joseon Dynasty. They reflects confucianism, a male-dominated society, totemism, shamanism and Yin-Yang and the five elements theory in agrarian society and community life. Daily dance Ganggangsullae has various types of costumes such as the fusion hanbok, saenghwal hanbok, cheering uniform and casual wear. They show modern color schemes. There is not any magical meaning from Yin-Yang and the five elements theory. Instead, they have individualism, liberty, equality and welfare in information-oriented society. So its costumes are easy and comfortable clothes. But traditional hanbok, fusion hanbok and saenghwal hanbok are inspired from Korean identiry. Even though traditional Ganggangsullae and daily dance Ganggangsullae have different costumes and ideology, they have a common denominator 'playfulness.' It will function as a key for Ganggangsullae to be performed continuously over the period.

History confirms that the eastern style was reflected in various parts of the western culture including clothing. In this paper we show some evidence that the influence of India on the French clothing during the neo-classical period(1789-1820) was substantial. Among others, the use of muslin, kashmir shawl and banyan during the period is greatly emphasized. The muslin imported from India was used as the textile for the chemise mown, a typical clothing during the period. Indian muslin was used, because it was of better quality compared to the muslin manufactured in England and France and it was not expensive. The kashmir shawl imported from kashmir in India was also a popular item in Europe not only because it matched well with simple color of chemise gown, but because it expressed the tone of Greek and Roman. Banyan which was most popular clothing worn by men in 18th century Europe originally came from India, which goes back to the Kaftan clothing in the Central Asia. Banyan was an informal home style clothing different from the conventional tight men's wear. It is true that the muslin, kashmir shawl, and banyan also became fashion items throughout the 19th and 20th century to the English and other European people. However, we limited our attention to the influence of India on France because we think the French Revolution and Napoleon's conquest of Egypt are far more important factors when considering the influence of Indian culture on Europe.

The object of this study was to investigate the attitudes toward the school uniforms with Hanbok image and design preferences for the improvement of the uniforms. Subjects were high school students wearing the westernstyle school uniforms. Questionnaires were distributed to 480 students and 400 responses among them were used for data analysis. Students replied to the questions about the attitudes toward the school uniforms with Hanbok image and the wearing of the uniforms, preferred design, and subjects' characteristics. Using the SPSS program, frequency and percent ratio of data were determined and t-test and $X^{2}$ test were performed. As the results, students' attitude toward the uniforms with Hanbok image showed to be positive, and girl students were more positive than boy students but they didn't want to wear the uniforms. It revealed that students wanted to be expressed Hanbok image in the uniforms partially and to be conceived their image warm, peaceful and smooth. It is concluded that the school uniforms with Hanbok image should be designed to display Korean traditional beauty and Hanbok image partially at the neckline or the end of the sleeve, keeping the shape of the westernstyle uniforms.
