The purpose of this study is to find out how middle and high school girls show their clothing attitudes and their life-style. clothing behavior. use their ornaments according to demographic variables. The subject of this study consists o 345 middle and high school girls living in Chung-Nam Province and Taejon Metropolitan City. SPSS/PC+ program was utilized to calculate frequency(N) mean value(M) and standard deviation (SD) for statistical analysis. Differences among the populations are examined through t-test. F-test and X2-test. The results of this study are as follow : 1. Correlation between the life style and demographic variables. Especially. life-style has significant difference(p<. 05) according to type of school. middle school girls have high tendency in the type of modern and fashion. Life-style has significant difference(p< .01) according to level of achievement studying, high level girls has high tendency in the type of practical and secure. 2. Correlation between the clothing behavior and demographic variables. According to type of school. middle school girls showed higher than high school girls in clothing conformity and clothing aesthetics. According to level of achievement studying, high level girls have high tendency in clothing conformity and clothing modesty. 3. Correlation between the use their ornaments and demographic variables. Buying the ornaments, higher-level achievement studying girl’s get information in show window. but lower-level achievement studying girl’s get information in TV or radio. The use of ornaments according to the site of school, most of school girls who live in small city or town use the ornaments as usual school life but school girls who live in big city use the ornaments to look good on their clothes. Following suggestions can be made based on the discussions above: It is necessary for us to have correct understanding about the correlation between the ornaments and clothing of school girls in order to lead them to have appropriate clothing behavior. Furthermore. it is required to construct a bridge linking a course of study to rational habits guidance which will provide us more appropriate tools for clothing behavior guidance.

In this study, based on the current curriculum of consumer education in high school with the advent of Web 2.0 age, I analyzed both the curriculum used by new information tools related with Web 2.0 age and the one used by traditional tools to find out the degree of necessity of consumer education for the high school students in proportion to the level of their informational ability. First, compared with the education of food, clothes and shelter in the curriculum of manual training and domestic science, the necessity, importance, and availability were low and the students had a lower level of interest than they had with the three factors mentioned above. Second, after dividing the sector of consumer education in the curriculum into three fields such as reasonable purchase and use, solution and prevention of consumer problems and forming a new consumer trend, I looked into the necessity of the teaching method using conventional tools and the one using new informational tools following Web 2.0 age respectively. Traditional tools were favored for the education of consumption-related laws and policies, consumers' rights for the general cause of consumer problem solving and preventing. For the generation of the new comsumer trend, the new information tools were preferred in the appreciation of consuming culture and the issues of consuming environment. Third, it was revealed that students' level of informational ethics was the highest at 5.55 while their level of information creation and processing was the lowest at 3.96 from the research of six categories of their informational ability.

The work presents a realistic human exposure assessment of indoor radon released from groundwater in a house. At first, a two-compartment model is developed to describe the generation and transfer of radon in indoor air from groundwater. The model is used to estimate radon concentrations profile of indoor air in a house us]ng by showering, washing clothes, and flushing toilets. Then, the study performs an uncertainty analysis of model input parameters to quantify the uncertainty in radon concentration profile. In order to estimate a daily internal dose of a specific tissue group in an adult through the inhalation of such indoor radon, 3 PBPK(Physiologically-Based Pharmaco-Kinetic) model is developed. Combining indoor radon profile and PBPK model is used to a realistic human assessment for such exposure. The results obtained from this study would be used to the evaluation of human risk by inhalation associated with the indoor radon released from groundwater.

This study examined factors, such as benefit perception, risk perception, product, and website, which affect consumer attitude toward overseas direct purchase. To achieve this, 298 Korean consumers who have experienced overseas direct purchasing were analyzed. The results show that delivery risk and product risk were the most influential determinants of the level of trust level in overseas direct purchase sites. In addition, the results of this study confirm that the level of trust in overseas direct purchase sites has a strong influence on both the intention to recommend and the intention to continue patronizing the site. Moreover, this study conducted a mean difference analysis according to the types of overseas direct purchases (overseas direct delivery, overseas purchasing agency, and overseas delivery agency) and product categories (clothes, food and beverage products, and household appliances). This study lists various practical implications that can be applied to each overseas direct purchase service by firm and consumer characteristics.

The purpose of this study was to investigate the teachers’attitudes toward the middle and high school student uniform. The questionnaire included independent variables about teacher themselves and school surroundings, and questions about teachers’attitudes toward school uniform. The participants were 316 middle and high school teachers in Chonbuk province. Means, standard deviations, frequencies, and percentages were calculated. ANOVA test was used for differences and scheffe-test was followed. The results were: 1. Teachers were content with “Students in uniform are upright and look more studentlkie.”“It’s easy to supervise students outdoors.”, and “There’s few efficiencies in coping with the temperature alternating.”, “Students in uniform hardly can reveal their originality.”and “It’s inconvenient for the students to be dynamic in uniform.” 2. Teachers in high schools and in private schools showed more positive attitudes toward uniform. And the male teachers, teachers graduated from general college, married teachers, and teachers who have a career of more than 20 years showed more positive attitudes toward uniform. More variables concerned about teacher themselves showed more significant differences than those about school surroundings. 3. Most of teachers showed positive attitudes toward uniform. The rank order of the reasons for the teacher’s positive attitudes were “Students in uniform are upright and look more studentlike.”, “It’s easy to supervise students outdoors.”, and “There’s no noticible distinction between the rich and the poor students.”The rank order of the reason for the teachers’negative at titudes were “Student in uniform could hardly reveal their originality.”, “It’s inconvenient for the student to be dynamic in uniform.”, and ”As they have to get the street clothes besides, economic burden becomes double in reality.”4. More than half of the teachers who are working at schools with uniform showed positive attitudes toward uniform. The rank order of reasons for the teachers’positive attitudes were “Students in uniform are upright and look more studentlike.”,“It’s easy to supervise students outdoors.”and “Economic burden could be decreased.”“The rank order of the reasons for the negative attitudes were “It’s inconvenient for the student to be dynamic in uniform.”, “Students in uniform could hardly reveal their originality.”, and “Students cannot feel free in mind with uniform.”5. Teachers overall showed positive attitudes toward uniform whether they work ar schools with uniform or without it.

We surveyed 223 road workers between 2017 July-August about wearing and satisfaction in order to find basic data to develop safety clothing that enhances visibility of motion and comfort while meeting international standards. It was found that most of the current warning clothing owned by road cleaners and about 2/3 of policemen clothes were provided by public institutions. The purpose of wearing, color, properties, satisfaction and protectiveness differed significantly by occupation. Second, the most popular response for the type and quantity of warning clothing was 2 sets of spring/autumn, summer, and winter type for road cleaners, whereas policemen chose 2 sets of all types plus a safety vest. Therefore, a top-level (3rd class) warning clothing study is required. Third, satisfaction ranked Moderate>Good>Poor; in addition, the main reason for satisfaction was that 'retroreflective tape increases safety at night (54.4%)' for road cleaners and 'the fluorescent color stands out (43.7%)' for policemen. Thus, it was accepted that visibility contributed to safety. Fourth, body-protectiveness was evaluated higher compared to wearing satisfaction, and it was recognized more by road cleaners than policemen. Overall satisfaction was higher for road cleaners versus policemen both in Seoul than Incheon. Fifth, the main dissatisfaction in both groups was 'low sweat absorbency' showing improving the air permeability, moisture regain and permeability was the highest priority. Finally, those working 8 hours a day tended to evaluate more positively the 6 properties of the material.

The study will analyze the costumes of the Scythians tribes who lived in the region of Altai in the 3-5 century BC. The purpose of this study is to prepare new material to re-examine the theory, which claims that the origin of the circular motives of korean costumes are to be found in the typology of the Scythian costumes. In this study, we analyzed the most recent reports of archaeological excavation about the unearthed clothes in the Pazyryk region and compared its information with european literature. The conclusion of this study is as follows: The jackets of the Pazyryk region are classified in two types, (1) opened jacket with narrow sleeve and (2) enclosed jacket with narrow sleeve. Trousers were separated by (1) narrow and (2) extreme wide trousers. The enclosed jacket of tunic form and extreme wide trousers are newly excavated. It proves, there was a vivid exchange between the Scythians and their neighboring cultures. It can be noted, that there existed a diverse Scythian culture of costumes, besides the commonly known clothing culture of the "Pazyryk-rider". Based upon the results of the previous research, it can be said that the opened jacket with narrow sleeve and narrow trousers are costume typologies which are common for all Scythian tribes of the whole Eurasian region. The hem of the edge of jacket is proven to be a connective element, which is common to all Scythian tribes.

Development of flame retarding polymer based materials has been studied actively due to the increase in use of polymers. The post treatment of manufactured fibers or the introduction of flame retardant into fibers is representative method for the way to improve the flame retardancy. Among the polymers, polyacrylonitrile (PAN), which is a precursor of carbon fiber, has been widely used for clothes. Due to low flame retardancy of PAN fiber (LOI value: 17~18%), the improvement of flame retardancy of PAN fiber is needed. In this review paper, we report preparation methods for the fabrication of post-treated (oxidization or chemical reaction) flame-retarding PAN fibers and composites composed of PAN and organic/inorganic materials (SiO₂, 2D materials or CNT).

This paper analyses the feasibility of using implantable antennas to detect and monitor tumors. We analyze this setting according to the wireless propagation loss and signal fading produced by human bodies and their environment in an indoor scenario. The study is based on the ITU-R propagation recommendations and prediction models for the planning of indoor radio communication systems and radio local area networks in the frequency range of 300 MHz to 100 GHz. We conduct primary estimations on 915 MHz and 2.4 GHz operating frequencies. The path loss presented in most short-range wireless implant devices does not take into account the human body as a channel itself, which causes additional losses to wireless designs. In this paper, we examine the propagation through the human body, including losses taken from bones, muscles, fat, and clothes, which results in a more accurate characterization and estimation of the channel. The results obtained from our simulation indicates a variation of the return loss of the spiral antenna when a tumor is located near the implant. This knowledge can be applied in medical detection, and monitoring of early tumors, by analyzing the electromagnetic field behavior of the implant. The tumor was modeled under CST Microwave Studio, using Wisconsin Diagnosis Breast Cancer Dataset. Features like the radius, texture, perimeter, area, and smoothness of the tumor are included along with their label data to determine whether the external shape has malignant or benign physiognomies. An explanation of the feasibility of the system deployment and technical recommendations to avoid interference is also described.

This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.
