Lead is ubiquitous in the human environment as a result of industrialization. China's rapid industrialization and traffic growth have increased the potential for lead emissions. Lead poisoning in children is one of the most common public health problems today, and it is entirely preventable. Children are more vulnerable to lead pollution and lead in their bodies can affect their nervous, circulatory, and digestive systems. Children are exposed to lead from different sources (such as paint, gasoline, and solder) and through different pathways (such as air, food, water, dust, and soil). Although all children are exposed to some lead from food, air, dust, and soil, some children are exposed to high dose sources of lead. Significant sources of lead for China's children include industrial emissions (often close to housing and schools), leaded gasoline, and occupational exposure that occurs when parents wear lead-contaminated clothing home from work, burning of coal for home heat and cooking, contaminated food, and some traditional medicines. To assess the blood lead level in children in China, a large-scale study was conducted in 19 cities among 9 provinces during 1997 to 2000. There were 6502 children, aged 3-5 years, were recruited in the study The result indicates that the mean blood lead level was 8.83ug/dl 3-5 year old living in city area. The mean blood lead level of boys was higher than that of girls (9.1l ug/dl vs 8.73ug/dl). Almost 30 percent childrens blood lead level exceeded 10ug/dl. The average blood lead level was higher than that of in 1985 (8.83ug/dl vs 8.lug/dl). An epidemiological study was carried on the children living around the cottage industries recycling the lead from battery. Nine hundreds fifty nine children, aged 5-12 years, living in lead polluted villages where the lead smelters located near the residential area and 207 control children live in unpolluted area were recruited in the study. The lead levels in air, soil, drinking water and crops were measured. The blood lead and ZnPP level were tested for all subjects. The results show that the local environment was polluted. The lead levels both in the air and crops were much higher than that of in control area. In the polluted area, the average blood level was 49.6ug/dl (rang 19.5-89.3ug/dl). Whereas, in the unpolluted area, the average blood level was 12.4ug/dl (rang 4.6-24.8ug/dl). This study indicates that in some countryside area, some cottage industries induce seriously lead pollution and cause children health problem. For the introducing of unleaded gasoline in some large cities, such as Beijing and Shanghai, the blood lead level showed a declined trend since 1997. By 2000, the use of leaded gasoline in motor vehicles has been prohibited in China. The most recent data available show that levels of lead in blood among children in Shanghai decreased from 8.3ug/dl in 1997 to 7.6ug/dl in 1999. The prevalence rate of children lead poisoning (blood lead >10ug/dl) was also decreased from 37.8% to 24.8%. In children living in downtown area, the blood lead level reduced dramatically. To explore the relationship between gene polymorphisms and individual susceptibility of lead poisoning, a molecular epidemiological study was conducted among children living in lead polluted environment. The result showed that the subjects with ALAD2 allele has higher ZPP level, and the subjects with VDR B allele has larger head circumference than only with b allele. In the present study, we demonstrated that ALAD genotypes modify lead effects on heme metabolism and VDR gene variants influence the skull development in highly exposed children. The polymorphism of ALAD and VDR genes might be the molecular inherited factor modifying the susceptibility of lead poisoning. Recently, Chinese government pays more attention to lead pollution and lead poisoning in children problem. The leaded gasoline was prohibited used in motor vehicles since 2000. The government has decided to have a clampdown on the high-polluted lead smelters for recycling the lead from battery in countryside. It is hopeful that the risk of lead poisoning in children will be decreased in the further

The purpose of this study was to investigate the maximal elongation rate and area expansion ratio of human skin in various postures. Five males and five females (male: $23{\pm}2yr$ in age, $177.9{\pm}4.8cm$ in height, $76.7{\pm}8.8kg$ in body weight, $24.2{\pm}2.5$ in BMI, $16.2{\pm}3.4%$ in body fat; female: $22{\pm}1yr$, $163.2{\pm}3.6cm$, $51.4{\pm}2.7kg$, $19.3{\pm}1.6$, $27.4{\pm}6.7%BF$) participated in this study. Measurements were conducted using a pen and tape on the elbow, knee, wrist, shoulder, and neck. Subjects held postures so that each joint of the body regions was bent at its maximal level. The results were as follows: 1) The maximal elongation rate of skin showed a significant difference among the regions: $16.6{\pm}3.4%$ for the wrist, $22.4{\pm}5.5%$ for the neck (back), $37.6{\pm}11.3%$ for the shoulder, $42.6{\pm}10.0%$ for the knee, and $43.9{\pm}4.0%$ for the elbow (p<0.05). 2) The maximal expansion rate of the body surface area had the greatest values on the elbow ($93.7{\pm}6.4%$) and knee ($74.8{\pm}10.8%$). 3) No significant difference was found between males and females. In summary, maximal values of skin elongation and expansion rates in vivo were greater than in vitro values known from previous reports. These results can be applied to develop electronic fibers or textiles for wearable tight fit work clothing as well as fitness wear.

This study compares fashion leaders and market mavens by examining the demographic characteristics of fashion leaders and market mavens and how they differ in their evaluation of store and shopping related attributes. Data originated from a national consumer mail survey in the United States. The survey included items measuring market mavenism, fashion leadership, store evaluative attributes, and personal information. Responses from 380 consumers were used for data analysis. Female consumers were found to be more active in word-of-mouth activities in general. Young consumers were more inclined to express fashion leadership while age was not related to market mavenism. A lower level of education increased tendencies for both market mavenism and fashion leadership. In terms of store evaluative criteria, the majority of items in the survey were more important as fashion leadership and market mavenism tendencies increased. Interestingly, the need for knowledgeable or helpful salespeople did not increase with fashion leadership tendencies. Also, fashion leaders were interested in easy return of merchandise and were likely to spend more time in the stores. This study sheds important light on how fashion leadership differ compared to market mavenism. By simultaneously examining fashion leadership and market mavenism using a strong sample base, this study provides sound evidence of how consumers interested in fashion may have differing needs for shopping.

The research aimed to establish the standard extraction procedure for examining brazilin, the major chromophoric substance of Sappanwood, using GC-MS with the ultimate goal of identifying the sappanwood dye in severely faded archaeological textiles. The amount of brazilin represented by the GC abundance was the largest when acetone was used as the extraction medium, followed by methanol. Shaking plate operated at room temperature was more effective than the waterbath shaker which was operated at $30^{\circ}C$. In both cases, the extraction method which incorporated one hour pre-soaking before the 12 hours of actual extraction resulted in a larger amount of brazilin detection than the extraction procedure without the one hour pre-soaking. In case of water extraction, pH 5 resulted in the most effective pH level for the extraction of brazilin, The best GC-MS parameter for detecting brazilin was to set the column temperature initially at $50^{\circ}C$. gradually increase to $210^{\circ}C$ at a $23^{\circ}C/min$ rate, finally increase to $305^{\circ}C$ at $30^{\circ}C/min$ rate, and hold for 14 minutes, and the MSD scan range at $75{\sim}400m/z$.

In this study fashion illustrations published in American Vogue from 1960 to 1989 were investigated. Among the large number of illustrations published in American Vogue in this period a considerable number of illustrations was chosen: from 1960 to 1969 143 editorial illustrations and 333 advertisement illustrations; from 1970 to 1979 34 editorial illustrations and 168 advertisement illustrations; from 1980 to 1989 123 editorial illustrations and 81 advertisement illustrations. In studying those illustrations the main point was put in finding characteristics and the changing trend of fashion Illustrations. In the sixties editorial fashion illustrations were published mainly during early sixties. The Illustrations of Rene Bouch, Evelyn Marcil, Dagmar and Eunice Moore Sloane took the space of editorials. Among those Illustrators Bouch published most frequently. The companies such as Galey & Lord, Lord & Taylor, Bergdorf Goodman, Bonwit Teller etc. used fashion illustrations for the advertisement. The name Kenneth Paul Block, Babara Pearlman and Dorothy Hood can be found very frequently on the illustrations for those companies. Antonio Lopez too published in 1963 some advertisement illustrations. In the seventies the total number of editorial fashion illustrations diminished drastically compared to the number in the sixties. Antonio published in 1973 and 74 fifteen illustrations, Joe Eula published from 1976 to 79 thirteen illustrations, and beside them Mats Gustavson published in 1978 six illustrations. The number of advertisement illustrations decreased a little, but many companies used fashion illustrations for the advertisement. The illustrator who worked most actively were Block and Fred Greenhill. In the eighties editorial illustrations experienced a "Renaissance". New high-level illustrators appeared and new fashion illustration magazines were found. Antonio played a central role among illustrators published for editorials in Vogue. In addition to him 15 other illustrators including Mats and Eula with various styles worked for editorials. In contrast to the flourishment of editorial illustrations the number of advertisement illustrations decreased compared to seventies as a result of the domination of fashion photography in this area. Today only few fashion illustrations can be found in fashion magazines. The magazines are dominated by fashion photographs. However fashion illustrations will not totally perish from fashion magazines, because it still has some valuable functions in fashion advertisement. Those functions cannot be fulfilled by photography. Therefore fashion illustration will survive in fashion magazine but playa minor role compared to photography.

Ancient Korean and China litteratures show us that it has been long since people from humbler classes to king most commonly used bast fabrics as materials of their cloth. According to the record of these ancient litteratures, highly developed fine bast fabrics and those woven in figures were used as tribute between ancient Korea and China. In this study we will make a brief research of the history of bast fabric culture from ancient times to the Korea Dynasty in which the bast fabric culture flourished and reached the summit of prosperity. After having compared the bast fabric culture of ancient Korea with that of ancient China in which the bast fabric culture developed very much and bast fabrics were used more commonly as materials of cloth than any other fabrics, we could come to conclusions as follows. 1. Names were given to bast fabrics according to the kinds of bast fibers, the degree of fineness and the containing of figures: Ma-po, Jeo, Jeo-po, Bag-jeo-po, Moon-jeo-po, Po and Se-po. The number of 'Seung' which indicated the degree of fineness was attached to the top of each name to show how fine they are. 2. While the bast fabric of 30 Seung is known to be the most fine one of the ancient China, in ancient Korea fine bast fabric of higher than 30 Seung was woven. This fact proves that the technique of weaving bast fabrics of the ancient Korea was more highly developed than that of ancient China. 3. In ancient China the highest Seung number of the ordinary clothes which were put on after putting off livery of grief was regulated to be 15. But in ancient Korea, Sil-la, it was regulated to be 28. Judging from this fact, we may say that the consumption level of the ancient Korean people in cloth was higher than that of the ancient China people. 4. The reason why in ancient Korea the technique of weaving bast fabrics was so highly developed is suppoed to be that the ancient Korean people preferred elegant, refine and simple taste in cloth. 5. The excellent bast fabric culture of the ancient Korea flowed into ancient Japan. It proves that Korea played an important part in the history of textile development of the world.

The textile industry is petting increased effort to manufacture the value-added products that gives the differentiated characters at every level of fiber and fabric production. The color is an important element to be used strategically in order to push up the value-added design. The colors of apparel products have a close relationship with the skin colors of consumers and their preference colors. This study was carried out to cluster the skin colors of the Korean women into several similar skin colors and to analyze their preference colors by the classified groups. We measured the skin colors of 354 Korean women. With color spectrometer, JX-777, we measured 4 points of the body; cheek with removing cosmetics off, forehead, rear neck and arm on the interior part near elbow. All subjects had been shown with 40 color chips and answered the preference colors and preference colors of apparel. Data were analysed to classify skin colors using K-means Cluster Analysis and Duncan test, Frequency and Chi square test on the preference colors about the clustered 3 groups. In doing so, we used in SPSS Win 10 statistical package. Findings were as fellows: 1) The skin colors of the Korean women were clustered into YR, R, and Y skin colors. The majority of the subjects, 324 observations had YR skin colors and the subjects were classified into 3 kinds of skin color groups who had YR skin colors. 2) The average skin colors of total 324 subjects was 5.23YR 6.49/4.09 in Munsell Color System(MCS), 66.56 in L value, 10.53 in a value, and 20.67 in b value. 3) The average skin color of Type 1 was 7.98YR 6.24/4.14 in MCS, 64.10 in L value, 15.05 in a value, and 24.0 in b value. For Type 2 was 7.30 YR 6.56/3.28 in MCS, 67.24 in L value, 6.89 in a value, and 18.4 in b value, and Type 3 was 7.01 YR 7.20/4.38 in MCS, 73.53 in L value, L 16.04 in a value, and 24.87 in b value. 4) The average face color of total 324 subjects was 7.31YR 6.65/3.56 in MCS, 68.13 in L value, 9.53 in a value, and 20.18 in b value. 5) The average face color of Type 1 was 4.19 YR 6.92/5.05 in MCS, 70.78 in L value, 13.2 in a value, and 25.32 in b value. For Type 2 was 5.24YR 6.33/3.79 in MCS, 64.94 in L value, 9.84 in a value, and 19.08 in b value. Type 3 was 5.4YR 6.85/4.68 in MCS, 70.1 in L value, 11.73 in a value, and 23.92 in b value. 6) The difference of mean values between the clustered 3 skin color groups showed significantly different except the a value of neck and H value of cheeks and H value of foreheads. 7) All 3 groups showed that the most preference colors and the most preference colors of apparel was 5R 4/14. and their preference colors were much more than the preference colors of apparel.

The colors of apparel have become an important element to be used strategically in order to give differentiated character at the level of fiber and fabric production. The colors of apparel have a close relationship with the skin colors of consumers and their preference colors. This study was carried out to classify the skin colors of Korean elderly women into several similar skin colors and to analyse their preference colors. Sample size was 471 Korean elderly women. With color spectrometer, JX-777, we measured 4 points of the body; cheek with removing cosmetics off, forehead, rear neck and arm on the interior part near elbow. All subjects had been shown with 40 color chips and answered the preference colors of apparel and the preference colors. Data weirs analysed to classify skin colors using K-means Cluster Analysis and Duncan test. Independent variables for Cluster Analysis were 12 variables out of L value, a value and b value of 4 points. In doing so, we used SPSS WIN 10 statistical package. Findings were as follows: 1) The skin colors of the Korean elderly women were composed of skin colors of YR, R, and Y. 2) 355 subjects were classified into 4 kinds of skin color groups. 3) The average face color of type 1 was 6.7YR 5.1/4.3 and 56 observations out of 355 subjects were composed of Type 1 and of Type 2 was 6.1YR 6.1/4.5 and 166 observations out of 355 and of 3 Type 6. YR 4.8/4.2 and 75 observations out of 355 and of Type was 6.17 YR 5.7/4.7 and 58 observations out of 355. 4) The average skin color of Type 1 was 7.0YR 5.9/4.4 and of Type 2 was 7.2YR 6.3/4.2 and of Type 3 was 7.0YR 6.2/4.2 and of Type 4 was 7.6YR 5.4/4.2 respectively. 5) The mean values of 12 variables between the 4 classified face color and skin color groups showed significantly different except H value of skin color. 6) All 4 groups showed that the most preference color of apparel and the most preference color were 2.5R 5/14 respectively.

The healing effect of the aroma treated fabrics with lavender and lemon aromas was investigated by assessing the autonomic nervous responses of human body. For this cause Lemon and lavender microcapsules were coated on a cotton fabric using a water-based acrylic binder, respectively. And the study created a total of four aroma treated fabrics at a concentration of 2% and 5% respectively. Electrocardiogram(ECG), skin conductance, and Blood flow, of ten participants were measured for 30 sec at a stable condition, at a stress status (working memory task), and at a stimulation status (after rubbing aroma treated fabrics). Subjective sensibilities of the aromas were also evaluated. With regard to the responses of the autonomic nervous system, in order to understand how the values gained after the normalization process would cause different physiological signals between the stable state and the aroma-stimulated state as well as between the stress state and the aroma-stimulated state, the study conducted a non-parametric test, friedman test as well and analyzed tendencies. LF/HF turned out to be significantly different to the stress state, and according to the results of the post-hoc comparison, lemon 5% presented statistically significant differences among the lavender 2%, lavender5%, lemon2%. Lemon 5% stimuli increased stress but stimuli consisting of the lavender 2%, the lavender 5% and the lemon 2% decreased stress because of a psychological rest. And the stimuli of the lavender 2%, the lavender 5%, the lemon 2% presented a healing effect in this research.

Honor guards‘ dress represented by royal carriage parade. This thesis studies the ceremonial dress worn by the ceremonial troops during the Hwa-sung Hang-hang Ban-cha drawing (華城幸行班次圖) in the Chosun dynasty of King Jung-jo. The purpose of this study is to understand the national level ceremony by closely looking into the traditional ceremonial dress and the various signs that were used at these events thereby enhancing the cultural status of the Jung-jo King period. The Hwa-sung Hang-hang Ban-cha drawing(華城幸行班次圖) has its characteristics and also has commonality between the garments worn at these ceremonies. These garments are a traditional heritage brought down from many ages before and is a reflection of the changes that have occurred within our everyday life. Among these many records the Bancha-do(班次圖) is a representation of records that show what was worn by both nobles down to the ceremonial troops. The uniforms of the ceremonial troops were not only huge in size but also very diverse according to rank and grade. They used strong true colors with colorful flags, ceremonial items and musical instruments. These all added to the grandeur of the ceremony. The ceremonial flag was itself a symbol and was the core of the whole ceremony and parade. These ceremonial flags represented the heaven, sun, moon, hill and animals as well as supernatural gods. All these showed change in shape, color and content by age and time. Also the Yongmun Gichi(Dragon flag: 龍紋旗幟) is a supernatural being representing the power and wish of the ruler. The Chunsang-mun represents the indivisible relationship between man and heaven and also a metaphor for absolute power. A close look at ceremonial instruments show a direct representation towards power such as an axe, spear and sword and integrated with other large ceremonial items not only provided a shade but was also a representation of worship. These all were a more or less representation of authority. The musical instruments expressed the absolute authority of the ruler and maintained the marching order and also added grandeur to the parade. A summary of the ceremonial troops in the As seen above, these national ceremonies were a representation of the present power of authority and the will to rule. These ideas and the philosophy of “ruled by heaven” is represented here in the uniforms and the ceremony itself. The Bicentennial anniversary of the Nung - hang of February 1795 will be an excellent opportunity to show and inherit the tradition and recreation of our heritage. In this view we must look at the color and shape of traditional dress to be able to inherit and learn from our ancestors.
