The paper details the development of a Korean style loungewear based on traditional Korean hanbok clothing. For this, we surveyed and collected data from 3,500 adults over 20 years of age. The questions were on their preferences of hanbok for both traditional and contemporary styles as well as loungewear. The survey showed that preferences for hanbok were high for both traditional and contemporary styles. The survey also suggests how a successful mass-produced Korean style loungewear should be designed to increase its popularity. It should feature comfortably simplified silhouettes, a selection of contemporary colors from Korean symbolic colors, modernized Korean textile surface designs, and easy-to-maintain healthy fabric. Based on these results, the development direction of Korean style loungewear was set and various loungewear samples were produced. Another group of survey participants were asked to try on samples and their preferences were surveyed. At the conclusion, a version that was most preferred among the participants was obtained. We suggest one-piece style and two-piece style designs with silhouettes based on the characteristics of traditional Korean costumes. The preferred fabric for loungewear was natural and soft cotton. We suggest the necessity and effectiveness of loungewear made with environment-friendly hanji-fabric. The main colors for loungewear were selected based on survey: blue, red, white, and saekdong (color stripes). We made color combinations with the main colors then applied the textile surface designs. The traditional Korean patterns of Hangeul (Korean letters), taegeuk (yin-yang), geometric figures, and samjogo (three-legged crow) were also chosen, and then loungewear using the textile designs was developed. The results have been shown on the "Han Style Fashion Show" by Jeonju City and exhibited in the "Seoul Living Design Fair" and the "International Art & Craft Trend Fair" in COEX, Seoul.

In this study, we evaluated the crow's fret of 95 Korean female by using mechanical assessments; Skin-Visiometer SV 600 and Dermascan C. Transparency profilometry (Skin Visiometer) were using a very thin skin print which allowed parallel light to pass through and was analysed immediately after production. High-frequency (20 MHz) ultrasonography (Dermascan C) enabled non-invasive evaluation in skin thickness and echodensity. We found a correlation between skin roughness and dermal density. Particularly, we showed a significant correlation between skin roughness (R2) and dermal thickness. Also, we demostrated a significant negative correlation between dermal density and dermal thickness (p < 0.05). Therefore, the ultrasonography system might be considered a very useful method in wrinkle evaluation with the transparency profilometry. Further study will be required.

Objectives : We investigated the skin properties on the periorbital region and cheek of Korean female according to age pattern by 7year based on Sang Go Cheun Jin Ron (上古天眞論) in So Moon (素問,) Methods : 49 Korean females, aged 21-56 years ($39.54{\pm}10.04$ years) were participated in this study. We measured the skin properties of periorbital region and cheek with SkinTouch (Amorepacific, Korea). Skin moisture, sebum, elasticity, lightness, roughness, area of wrinkle, depth of wrinkle were assessed. Results : Differences were noticed depending on the site and age. The level of moisture was higher on the eyelid than crow's feet. The level of lightness and elasticity were lower on the periorbital region than cheek. Skin lightness was highest on group1(under 28y) and lowest on group5(over 49y). Skin roughness was highest on group1(under 28y) and lowest on group4(over 42y under 49y). The level of wrinkle are was lowest on group1(under 28y) and highest on group 5(over49y). The level of wrinkle depth was lowest on group1(under 28y) and highest on group 4(over 42y under 49y). Conclusion : Unique aging pattern by 7 years of female is reflected to diverse skin properties of eyes. It can be possible to apply the theory on Sang Go Cheun Jin Ron (上古天眞論) to practical use in dermatology and cosmetic.

In this study, we used HARVEST, a timber management strategy assessment tool, to evaluate alternative forest planning strategies on spatial pattern of cutting blocks. We applied the tool to the Gwangreung Experimental Forest (GEF) as a case study. The harvest schedules developed for GEF using a linear programming model was used to assess spatial patterns of cutting blocks under different management constraints. The results show that the allowable maximum harvest size largely affects the number, size, and distribution of cutting blocks. We also found that spatial dispersion methods and adjacency constraints could be used as an effective means to control spatial allocation of cutting blocks in order to meet certain forest ecosystem management goals.

In today's society, where people look younger than their chronological age due to improvements in the quality of life, there is a gaining interest in anti-aging and how people compare to those in the same age group. We evaluated the wrinkle index, which is the most important attribute amongst skin parameters, to evaluate external age (wrinkle age). The wrinkles of the whole face were scored by divided 8 areas (forehead, glabella, nasal root, upper eyelid, lower eyelid, crow's feet, nasolabial groove and perioral skin) and analyzed the correlation between chronological age and skin parameters. 206 subjects (Korean female, n = 105 and Mongolians female, n = 101) were enrolled. Subjects were divided into four groups by ages: 20s, 30s, 40s, and 50s. Wrinkle scores of 8 areas were evaluated and developed a calculation formula based on the wrinkle scores. Skin characteristic parameters were measured about skin elasticity, pore, wrinkle, sebum secretion. There was no difference between the calculated ages and the chronological ages in Korean women. On the other hand, Mongolian looked older than chronological age by 9 years. The correlation between the facial wrinkle ages and skin physiology parameters was presented in the order of skin elasticity > pore or crow's feet > skin tone > sebum secretion in both countries. Skin elasticity represented the most related parameter with the facial wrinkle ages. This study identified the skin wrinkle patterns of Korean and Mongolian women and the wrinkle age calculation formula developed from this study can be used as a tool for calculating the facial wrinkle ages in cosmetic studies.

This study looks into historical genealogy of autonomy in art criticism on modernism and presents the view of the judgment and correction about that. A matter of autonomy in art appeared in the attempt to totally reconsider and upset the theory of 'Mimesis' or 'Representation' which was the basis of traditional aesthetic theory. In the traditional theory of representation, they assumed primary image exists first and then tried to obtain visual similarity to it through art works. However, in the theory of autonomy in modernism, they maintained the reduction to pure form' or medium', regarding what art works represents and how similar to primary image are not the true essence of art. In the early 20th century, C. Bell laid the foundation stone of the theory of Formalism', providing that a matter of autonomy is significant form', which is the combination of lines and colors Aesthetic autonomy theory came to a climax by C. Greenberg, who systemized art criticism on modernism in the middle 20th century. According to his theory, the pursuit of the essence of form resulted in the specificity of medium' and flatness. They thought that the autonomy of art would be achieved by eliminating outward social factors from art works. This theory ended by Minimalism preventing the instructive function of art work and only emphasizing its material property. Since the middle 20th century, the autonomy theory was confronted with the limit and intense attack because it resulted in this fixed canon and materialism, so they began laying emphasis on those extrinsic factors around art works such as human life, society, history, and so on. This study focuses on arguing and complementing the limit of autonomy such as the adhesive and fixed canon, and then defining the more dynamic area of it. For this, first, I introduced the view of T. J. Clark and T. Crow who criticized the aesthetic autonomy theory. They denied the transcendental structure of form, and found form only in the association with substantial life and society. And they insisted the dynamism of form by emphasizing form as a result of negation insisted by avant-garde. Second, I researched the view of A. C, Danto and M. Fried, who complemented the traditional autonomy theory. They made autonomy emerge from the fixation of form like flatness through connecting essentialism with historical view. In conclusion, I insist that autonomic position of art make it possible to connect or mediate between material form and human or social elements. Therefore, autonomy should not be reduced to the axis of form or that of society but make interaction between two heterogeneous axes.

This study evaluated anti-wrinkle effect using toner and lotion containing ginsenoside Rg3 enriched black ginseng in oriental medicine like Liriope platy phyllla, Inonotus obliquus, Glycyrrhiza glabra and nourishing of the blood and energy(Atractylodes japonica, Poria cocos Wolf, Angelica gigas, Rehmanniae Radix Preparata, Cnidii Rhizoma, Paeonia lactiflora). 6 female adults on average at the age of 42.5 applied lotion after toner under the normal conditions of use on the face including crow's feed area, twice a day (in the morning and evening) for 4weeks. After 4 weeks, the replica of eye wrinkle was made and analyzed the image. The result was decreased in R1($3.15{\pm}0.35$ to $2.28{\pm}0.22$), R2($2.99{\pm}0.37$ to $2.13{\pm}0.21$), R3($2.09{\pm}0.31$ to $1.56{\pm}0.18$), R4($0.37{\pm}0.05$ to $0.29{\pm}0.03$), and R5($0.89{\pm}0.1$ to $0.75{\pm}0.06$)(P<0.05). Therefore, oriental medicine cosmetics containing black ginseng may play a role anti-wrinkle.

In order to see if any suppressor system for the SD action was involved in natural populations of D. melanogaster samples from the populations of nine localities in Korea, Choonchun, Yusoo, Namhai, Shinchon(Seoul), Kwangjoo(Kyunggi), Koonsan, Kwangjoo(Chunnam), Jejoo and Pusan were analyzed by using the mating scheme for locating the suppressor on chromosome pairs. And also two kinds of recombinant SD lines R-1, the American line and $R(SD^NH -1)-1$, the Japanese one were used in order to see any difference of the response of the suppressor for differently originated SD. The results of the experiment are given below. (1) The suppressor system was involved in all lines of natural populations from nine localities of Korea. (2) Most of the suppressors were found to be located on the X chromosome and only a few lines from three populations showed to carry the suppressors on the second chromosome and on the third or fourth chromosoem. (3) The response of the suppressor for differently originated SD lines showed no significant difference.

Reliability growth rate (or reliability growth curve slope) have the two cases of trend as a constant or changing one during the reliability growth testing. The changing case is very common situation. The reasons of reliability growth rate changing are that the failures to follow the NHPP (None-Homogeneous Poisson Process), and the solutions implemented during test to break out other problems or not to take out all of the root cause permanently. If the changing were big, the "Goodness of Fit (GOF)" of reliability growth curve to test data would be very low and then reduce the accuracy of assessing result with test data. In this research, we are using Duane model and AMSAA model for assessing test data and projecting the reliability level of complex and repairable system as like construction equipment and vehicle. In case of no changing in reliability growth rate, it is reasonable for reliability engineer to implement the original Duane model (1964) and Crow-AMSAA model (1975) for the assessment and projection activity. However, in case of reliability growth rate changing, it is necessary to find the method to increase the "GOF" of reliability growth curves to test data. To increase GOF of reliability growth curves, it is necessary to find the proper parameter calculation method of interesting reliability growth models that are applicable to the situation of reliability growth rate changing. Since the Duane and AMSAA models have a characteristic to get more strong influence from the initial test (or failure) data than the latest one, the both models have a limitation to contain the latest test data information that is more important and better to assess test data in view of accuracy, especially when the reliability growth rate changing. The main objective of this research is to find the parameter calculation method to reflect the latest test data in the case of reliability growth rate changing. According to my experience in vehicle and construction equipment developments over 18 years, over the 90% in the total development cases are with such changing during the developing test. The objective of this research was to develop the newly assessing method and the process for GOF level increasing in case of reliability growth rate changing that would contribute to achieve more accurate assessing and projecting result. We also developed the new evaluation method for GOF that are applicable to the both models as Duane and AMSAA, so it is possible to compare it between models and check the effectiveness of new parameter calculation methods in any interesting situation. These research results can reduce the decision error for development process and business control with the accurately assessing and projecting result.
