The purpose of this study was to find out the usage of animation and its relation to the social values and clothing behaviour of adolescents. A survey was conducted in four different high schools in the metropolitan area (Seoul) and 187copies were analyzed by SPSS 12.0 package. The results were as follows; First, According to Usage survey, a number of adolescents watched animations mainly through the internet and 39% of them used the internet $2{\sim}3$ times a week. The most watched genre of animation was action/science-fiction but some differences were observed between male students and female students. Male students enjoyed action/science-fiction, comedy and drama/romance, whereas female students enjoyed drama/romance, action/science-fiction and comedy in the decreasing order. Second, It was found that the favorite genre of animation by adolescents had influence on their community mind and materialism. The most significant genre affectingcommunity life was drama/romance and the one affecting materialism of adolescents was action/science-fiction. Third, Materialism had a significant influence on clothing conformity and the next was community mind. Only materialism proved to be a significant variable affecting fashion followers. In conclusion, the results of this study showed that the adolescents' community life and materialism were significantly influenced by their favorite genre of the animation, and their social values were related to their clothing behaviors.

In the era of the 4th Industrial Revolution customers living began to come out, not inside the purchase funnel. Due to the diversity of product selection and the increase in digital channels, the way customers search for information and purchase it is changing innovatively. So, the customer journey in the digital age is much more complicated than the traditional funnel model suggests. Unlike many previous studies, this study was conducted for 1,200 customers in four product groups of fashion, automobile, cosmetics, and online shopping malls. As a result of the study, we investigated how digital self-efficacy plays a role in purchasing in a series of processes in which digital experience affects customer satisfaction and finally affects purchase. As a theoretical implication, as a result of introducing and testing digital self efficacy as moderated mediation effect. the digital self-efficacy between customer satisfaction and customer loyalty were determined to play a moderated mediation effect role. As a practical implication, it was necessary to actively utilize digital marketing for customers with high digital self-efficacy, but it was suggested that customers with low digital self-efficacy need to be careful about digital marketing fatigue.

To examine the new practical utilization of mucilages in Opuntia humifusa, the Korean pear cactus, the polysaccharides were isolated from O. humifusa, and immuno-stimulating activities were assayed. The main polysaccharide, CNC-E, was prepared by a commercial enzyme treatment, water extraction, and ethanol precipitation. The molecular mass of CNC-E was estimated to be about 700 kDa, and it consisted mainly of arabinose, galactose and xylose in addition to two minor sugars such as rhamnose and fucose. On the other hand, CNC-E showed considerably high splenocyte proliferation activity in a dose-dependent manner. Peritoneal macrophages stimulated with CNC-E produced cytokines such as IL-6, IL-12, IL-10, and TNF-${\alpha}$. The intravenous administration of CNC-E significantly augmented the cytotoxicity of natural killer (NK) cells against Yac-1 tumor cells. Especially, NK cells obtained from the mice treated with $100{\mu}g$ of CNC-E showed threefold higher cytolytic activity than those of untreated mice. CNC-E also showed potent anti-complementary activity in a dose-dependent fashion. Identification of C3 activation products by the crossed immunoelectrophoresis using anti-human C3 and the anti-complementary activity of CNC-E in a $Ca^{2+}$-free condition suggested complement activations by CNC-E that occur via both alternative and classical pathways. These results indicate that Korean pear cactus contains selected polysaccharides that provide immuno-stimulating activities beneficial to human health.

The subject of study concerns the color characteristics of clothing/accessories from �Chosun�a nd modern Korea. It particularly focuses on the colors of the �Jeogori? traditional jacket) which represents Korean traditional clothing. Color data were collected from 353 woman�s �Jegori�s from �Chosun�a nd modern Korea and divided into the predominant colors & sub colors, and analyzed with HV/C and PCCS. According to the analysis, the representative the predominant color of 'Chosun Jeogori' for woman is YR, Y and side one is R, YR. The p, dp, sf, ltg colors are frequently found and the freshness of most of them is medium or low which shows a calm-feeling. The p, and ltg tones are often found as a the predominant color and p, dp are also often found as a the side color. In the 'Chosun Jeogori' for woman, the predominant colors and the side colors spread in a similar frequency and most of them have medium or low freshness of the color that shows a calm-feeling. The side color is one of the R colors and it shows characteristics of traditional coloring such as �Jajoo Goreum? Among the �Jeogori�f or modern women, the R, YR, Y, and B colors are often used for the single-color �Jeogori? the Y, GY, N, G colors are for the colorful �Jeogori? The P, lt, and b tons of the color are often used for a single-color �Jeogori�a nd the p, lt, and W are for the colorful �Jeogori? For the colorful �Jeogori? the side color have a high freshness which shows that a strong image was used frequently as the dp, s, dk tons of the color were often used. According to an analysis of the coloring, the predominant color and the side color of �Chosun Jeogori�a re applied to create a harmony of analogy & contrast in one aspect of Moon & Spencer�s view. It is found that the predominant color and the side color are similar or contrasting in one view of the color harmony, except that the traditional the �Jeogori�i s colored by ideological and symbolic meanings. The predominant color and the side color of modern the �Jeogori�a re complementary colors which are applied to the indistinct relationship or contrasting harmony in one aspect of Moon & Spencer�s view of the color harmony. The characteristics of the color as above show that traditional the �Jeogori�r egards the side color as both the harmony of the colors in general and also of symbolic meaning, while modern the �Jeogori�f or woman has a tendency toward a cultural transition and is mixed with new colors focusing more on its the predominant color than on the general harmony and character of ideological & traditional coloring.

Rates of the reaction for p-nitro benzyl chloride, benzyl chloride and p-methyl benzyl chloride with pyridine in methanol solvent have been measured by an electric conductivity method at 40$^{\circ}$C and 50$^{\circ}$C under various pressures (1∼2000bar). Pseudo first-order rate constants and second-order rate constants were determined. Rates of these reactions were increased in the order p-NO$_2$ < p-H < p-CH$_3$ and increased with temperature, pressure and concentration of pyridine. From those rate constants, the activation parameters were evaluated. The activation volume and the activation compressibility coefficient are both negative values, but the activation enthalpy is positive and the activation entropy is large negative value. From the evaluation of the ground state and transition state which was resulted from substituents and pressure, it was found that this reaction proceeds through S$_N$2 reaction, and S$_N$2 fashion is slightly disappeared as pressure increases.

Objective: The aim of this study was to explore the influence of outdoor weather conditions on subjective responses during physical activity. Background: The largest difference between indoor and outdoor conditions is the existence of the sun. The heat load from the sun has an influence on the heat gain of the human body and the intense degree of solar radiation affected thermal comfort. Method: Thirty eight people were exposed to a range of climatic conditions in the UK. Weather in England does not have extremely hot and cold temperature, and the current study was conducted under warm (summer and autumn) and cool (spring and summer) climates. Measurements of the climate included air temperature, radiant temperature (including solar load), humidity and wind around the subjects. Subjective responses were taken and physiological measurements included internal body temperature, heart rate and sweat loss. Results: This study was conducted under four kinds of environmental conditions and the environmental measurement was performed in September, December, March, and June. The values for sensation, comfort, preference, and pleasantness about four conditions were from 'neutral' to 'warm', from 'not uncomfortable' to 'slightly comfortable', from 'slightly cooler' to 'slightly warmer', and from 'neither pleasant nor unpleasant' and 'slightly unpleasant', respectively. All subjective responses showed differences depending on air temperature and wind speed, and had correlations with air temperature and wind speed (p<0.05). However, subjective responses showed no differences depending on the radiant temperature. The combined effects of environmental parameters were showed on some subjective responses. The combined effects of air temperature and radiant temperature on thermal sensation and pleasantness were significant. The combined effects of metabolic rate with air temperature, wind speed and solar radiation respectively have influences on some subjective responses. In the case of the relationships among subjective responses, thermal sensation had significant correlations with all subjective responses. The largest relationship was shown between preference and thermal sensation but acceptance showed the lowest relationship with the other subjective responses. Conclusion: The ranges of air temperature, radiant temperature, wind speed and solar radiation were $6.7^{\circ}C$ to $24.7^{\circ}C$, $17.9^{\circ}C$ to $56.6^{\circ}C$, $0.84ms^{-1}$ to $2.4ms^{-1}$, and $123Wm^{-2}$ to $876Wm^{-2}$ respectively. Each of air temperature and wind speed had significant relationships with subjective responses. The combined effects of environmental parameters on subjective responses were shown. Each radiant temperature and solar radiation did not show any relationships with subjective responses but the combinations of each radiant temperature and solar radiation with other environmental parameters had influences on subjective responses. The combinations of metabolic rate with air temperature, wind speed and solar radiation respectively have influences on subjective responses although metabolic rate alone hardly made influences on them. There were also significant relationships among subjective responses, and pleasantness generally showed relatively high relationships with comfort, preference, acceptance and satisfaction. Application: Subjective responses might be utilized to predict thermal stress of human and the application products reflecting human subjective responses might apply to the different fields such as fashion technology, wearable devices, and environmental design considering human's response etc.

Soybean seeds contain high amounts of isoflavones that display biological effects and isoflavone content of soybean seed can vary by year, environment, and genotype. Objective of this study was to identify quantitative trait loci that underlie isoflavone content in soybean seeds. The study involved 85 $F_2$ populations derived from Korean soybean cultivar 'Kwangkyo' and wild type soybean 'IT182305' for QTL analysis associated with isoflavone content. Isoflavone content of seeds was determined by HPLC. The genetic map of 33 linkage groups with 207 markers was constructed. The linkage map spanned 2,607.5 cM across all 33 linkage groups. The average linkage distance between pair of markers among all linkage groups was 12.6 cM in Kosambi map units. Isoflavone content in $F_2$ generations varied in a fashion that suggested a continuous, polygenic inheritance. Eleven markers (4 RAPD, 3 SSR, 4 AFLP) were significantly associated with isoflavone content. Only two markers, Satt419 and CTCGAG3 had F-tests that were significant at P<0.01 in $F_2$ generation for isoflavone content. Interval mapping using the $F_2$ data revealed only two putative QTLs for isoflavone content. The peak QTL region on linkage group 3, which was near OPAG03c, explained $14\%$ variation for isoflavone content. The peak QTL region on linkage group 5, which was located near OPN14 accounted for $35.3\%$ variation for isoflavone content. Using both Map-Maker-QTL $(LOD{\geq}2.0)$ and single-factor analysis $(P{\leq}0.05)$, one marker, CTCGAG3 in linkage group 3 was associated with QTLs for isoflavone content. This information would then be used in identification of QTLs for isoflavone content with precision

Between August 1996 and August 1997, 22 patients underwent extracardiac Fontan operations. The basic diagnoses included univentricular heart of the right ventricular type (n=12); univentricular heart of the left ventricular type (n=4); tricuspid atresia (n=4); left isomerism, transposition of great arteries, ventricular septal defect and pulmonary stenosis (n=1); and criss-cross heart with uneven ventricle (n=1). The median age of the 14 men and 8 women was 29 months (range from 21 months to 26 years). Previous procedures included bidirectional cavopulmonary shunt (n=15, interval=15.6$\pm$3.4 months), Kawashima operation (n=4, interval=37.5$\pm$20 months), and classic Glenn shunt (n=1, interval=14 years). In 2 patients, extracardiac Fontan operations were done without any previous procedures. A 16- to 22-mm flexible Gore-Tex tube graft (n=18), Hemashield graft (n=3), or, alternatively, a nonvalved aortic allograft (n=1) was cut and anastomosed end-to-end between inferior vena cava and undersurface of pulmonary artery using Gore-Tex or Prolene suture in a running fashion. In risk Fontan patients (n=12), a communication between the extracardiac conduit and the right atrium was constructed. In the most 13 recent patients, the procedures were done without cross-clamping of the aorta and with a beating heart. Operative mortality was 9.1% (n=2). Complications included persistent chest tube drainage for more than 7 days (n=5), chorea (n=2), and low cardiac output (n=1). There were no late deaths. Follow-up echocardiogram (mean: 6 months) demonstrated satisfactory hemodynamic results in the surviving 20 patients. Potential advantages of this technique consist of minimization of surgical manipulation of atrial tissue, reduction or elimination of myocardial ischemia, creationof a uniform and stable inferior vena cava-to-pulmonary artery conduit, and increased flexibility and safety in certain high-risk patients such as those with increased pulmonary vascular resistance, pulmonary hypertension, and impaired ventricular function. Further investigations during a longer follow-up are needed to confirm the intermediate and long-term results, especially the reduction of late atrial arrhythmias.

The color yellow was considered from ancient time to the Chosun Dynasty as the central color. Thus, this color became the royal color for the costumes in the palace. It is generally known to usthat the color yellow was controled in use both for the general public and in the royal palaces. However, in the later part of Chosun Dynasty, the color yellow was used not only for the king's costumes but also used for women's tops and for the linings of clothing. Especially, in some of the costumes that belonged to the later period of the Chosun Dynasty, we can still see lots of bright yellow tops. Also there are many green dyed official robes and various costumes for women. It is a true fact that people could not derive the color green from the plants as they did with yellow. The only way they could make the color green was to mix indigo and yellow together. By repeating the difficult process of making various dyes constantly during many centuries, the Korean people developed the marvelous technique of making natural color. Those plants used to make the color yellow are ; Gardenia, Phellodendron amurense, Turmeric, Coptis, Safflower, Arthraxon hispidus, Styphnolobium japonicum. While synthetic dye causes pollution, natural coloring by plants is as safe and useful as the color itself is lovely. Yet it is tragic to know that this traditional culture of making beautiful natural colors was cut off. There is no way to know today the traditionally correct method to derive colors from the plants. Therefore, it is our aim and challenge to find out the original way to dye and develop it and preserve it as our non-polluted folk art. In regard to natural dyeing, we must say that is very difficult to prepare and preserve natural dyes. In the first place, people had to get the right plants at an appropriate time. Then they could not keep those plants too long. Finally, much depended upon the mordant as well as various conditions and dyeing procedures. All those things influenced greatly the quality of color, some times producing a very pretty color and other times a very dull one. It is very appropriate that the natural dye art should be recognized and appreciated anew by Korea since it provides satisfaction to historical and folk artistic demands as well as to those of fashion conscious modern society for high quality consumption items. We propose two stages of development. The first stage is to explore native dye plants and encourage their cultivation. The second stage is to extract from the plants desirable dye which will enhance national culture.

This study studies the fabrics from excavated 17th century tombs of Mrs. Min from Yeoheung family(1586~1656), Yeo-on Kim(1596~1665) and Won-rip Choi(1618~1690) and attempts to clarify the relationship between the fashion trend in fabrics of those times and the background behind it by viewing and examining the proportion of twill fabrics to the total silk fabrics and the characteristics of its weave and patterns. Looking into fabrics from the above tombs, twill fabrics accounted for 10.4%(13 pieces) 19.3%(16 pieces) and 9.2%(9 pieces) of total silk fabrics in each of the respective tombs. This forms a remarkable contrast with the fact that there was only one piece of twill silk fabrics(0.5%) and not any from the 16th century tombs of Mrs. Yoon from Papyeong family (0.5%) and Soo-ryoon Sim(0%). In particular, the percentage of hwamun-neung(patterned twill fabrics) in each of the tombs is 8.0%(10 pieces), 13.3%(11 pieces), 9.2%(9 pieces), which is much higher than that of non-patterned one. This is common to the twill fabrics from above three 17th century tombs. Patterns of hwamun-neung(patterned twill), simplified small flower patterns or geometrical figures, from the three excavated tombs are mostly arranged sporadically with blank space. It is supposed that these figurative characteristics reflected the aesthetic sense of the gentry at that time which valued simplicity and moderation for their Confucian standard. This phenomenon of increased use and production of twill fabrics in the 17th century resulted from different factors such as wars like Japanese Invasion of Korea(1592~1598), economic difficulty, government regulations against the production of high-class fabrics, development of weaving skill and its fixation, changes of fabric production environments, and changes of aesthetic sense preferring naive and moderate things to showy ones. As for the weaving characteristics of twill fabrics from the three 17th century tombs 3 leaf warp-faced twill was often used for the ground texture and 4 leaf warp-faced one was occasionally used. For pattern texture 6 leaf weft-faced twill was frequently used, 4 leaf weft-faced twill and 3 leaf weft-faced twill were used at times, and floating one was occasionally used as well.
