  • The inspiration and its application in fashion design is considered as one of the important factors in boosting the fashion arena. Many inspirations are adapted in fashion de-sign and they make the fashion design unique and characteristic. In this study many fashion designs are analyzed to find what kind of inspirations were adapted and utilized for the fashion design in reality. The nature historic costumes ethcin costumes arts sciences literature music sports were revealed as the sources of fashion inspiration.l The concerns on the environments movies and dramas could provide inspirations in fashion as well. Several contents or steps were studied to provide the one of the example of appli-cations as follows: 1. The works of Marc Chagall were analized to figure out and several plastic characteristics from his works were revealed such as fantastic strong colors unreal animal pattern or their details his wife and friends various divisions of the surface and so on. These attributes had been favored in depiction of his works to ex-press his home town or nostalgia. 2. '90s fashion designs inspired by the works of Chagall were analized to find out the meth-odology or the process of designs. The same Chagall colors were used in design and similar pattern were expressed through beaded work or printing jobs. The surface designs such as printing were the most prefered method in adapting the inspirations. 3. The plastic characteristics of the work of Chagall were attempted in clothing design and construction. The color combination patterns which remind the animals the surface divisions were used in design ot practive the methodologies.

  • Floating debris provides substrates for dispersal of organisms by ocean currents, including algae that thrive on plastics. The 2011 earthquake and tsunami in Tohuku, Japan resulted in large amounts of debris carried by the North Pacific Current to North America from 2012 to 2016. In 2015-2016, the plastics in the debris bore a complex biota including pink algal crusts. One sample (JAW4874) was isolated into culture and a three-gene phylogeny (psbA, rbcL, and SSU) indicated it was an unknown member of the red algal class Stylonematophyceae. It is a small pulvinate crust of radiating, branched, uniseriate filaments with cells containing a single centrally suspended nucleus and a single purple to pink, multi-lobed, parietal plastid lacking a pyrenoid. Cells can be released as spores that attach and germinate to form straight filaments by transverse apical cell divisions, and subsequent longitudinal and oblique intercalary divisions produce masses of lateral branches. This alga is named Tsunamia transpacifica gen. nov. et sp. nov. Sequencing of additional samples of red algal crusts on plastics revealed another undescribed Stylonematophycean species, suggesting that these algae may be frequent on drift oceanic plastics.

  • This study is conducted to suggest ways to mitigate the mismatch phenomenon between job seekers who want to find right company for themselves and companies looking for appropriate new employees. For this purpose, this study improves the company assessment framework reflecting job seekers interests by using fuzzy analytic hierarchy process. The improved evaluation framework is a three-level hierarchical structure, where there are 4 groups at the top level, 12 factors at the intermediate level and 36 indexes at the bottom level. For the empirical analysis of the applicants preferences based on the improved model, a survey for F-AHP analysis is carried out to university students and then priorities of components in the evaluation model are calculated. Moreover, the differences of priority of the company assessment framework are analyzed for different genders, college years, and major divisions. The results show that job seekers' most concerning factors are wages, stability, working environments, and labor deal, which are ranked highly in this order and the differences in preferences for each type of job seekers (genders, college years, and major divisions) are obvious. The results also show that the male prefers wages to environment, on the other hand female does working environment to wages.

  • Electrolessly deposited Co (Re,P) was investigated as a possible capping layer for Cu wires. 50 nm Co (Re,P) films were deposited on Cu/Ti-coated silicon wafers which acted as a catalytic seed and an adhesion layer, respectively. To obtain the optimized bath composition, electroless deposition was studied through an electrochemical approach via a linear sweep voltammetry analysis. The results of using this method showed that the best deposition conditions were a $CoSO_4$ concentration of 0.082 mol/l, a solution pH of 9, a $KReO_4$ concentration of 0.0003 mol/l and sodium hypophosphite concentration of 0.1 mol/L at $80^{\circ}C$. The thermal stability of the Co (Re,P) layer as a barrier preventing Cu was evaluated using Auger electron spectroscopy and a Scanning calorimeter. The measurement results showed that Re impurities stabilized the h.c.p. phase up to $550^{\circ}C$ and that the Co (Re,P) film efficiently blocked Cu diffusion under an annealing temperature of $400^{\circ}C$ for 1hr. The good barrier properties that were observed can be explained by the nano-sized grains along with the blocking effect of the impurities at the fast diffusion path of the grain boundaries. The transformation temperature from the amorphous to crystal structure is increased by doping the Re.

  • This study examined the anatomical relationships along with the variability of the facial nerve trunk and its branches with an emphasis on the intraparotid connections between the divisions. And histomorphometric observations of the facial nerve branches and fascicles were performed on 40 Korean half-heads. The facial nerve trunk was bifurcated into two main divisions(35/40, 87.5%) and the other five cases were divided into a trifurcation pattern. According to the origin of the buccal branch, the branching patterns of the facia l nerve were classified into four categories. Communications between the facial and auriculotemporal nerve branches were observed in 37 out of 40 cases(92.5%). In the histological observation, the buccal branch had the greatest number of branches(3.47), however the zygomatic branch had the largest diameters(0.93mm). This detailed description of the facial nerve anatomy wi ll provide useful information for surgical procedures such as a tumor resection. a facial nerve reconstruction, autonerve graft. and facelift.

  • The purpose of the study was to investigate how students understand multiplication and division of fractions and how their understanding influences the solutions of fractional word problems. Thirteen students from 5th to 6th grades were involved in the study. Students' understanding of operations with fractions was categorized into "a part of the parts", "multiplicative comparison", "equal groups", "area of a rectangular", and "computational procedures of fractional multiplication (e.g., multiply the numerators and denominators separately)" for multiplications, and "sharing", "measuring", "multiplicative inverse", and "computational procedures of fractional division (e.g., multiply by the reciprocal)" for divisions. Most students understood multiplications as a situation of multiplicative comparison, and divisions as a situation of measuring. In addition, some students understood operations of fractions as computational procedures without associating these operations with the particular situations (e.g., equal groups, sharing). Most students tended to solve the word problems based on their semantic structure of these operations. Students with the same understanding of multiplication and division of fractions showed some commonalities during solving word problems. Particularly, some students who understood operations on fractions as computational procedures without assigning meanings could not solve word problems with fractions successfully compared to other students.

  • The objectives of this study were to investigate the followers's perception of the behavioral characteristics of middle managers' leadership styles and the relationship between middle managers' behavioral characteristics by leadership style and followers' trust in middle managers. The data were collected from the officials of the Rural Development Administration(RDA) of Korea in September, 2001. A total of 215 questionnaires out of 232 distributed were collected and 211 valid ones analyzed. The results from the study were as follows: First, on the leadership styles of the middle managers of RDA, the perception points of the staffs of offices/divisions were 3.56 points in servant leadership style, 3.48 points in transformational leadership style and 3.51 in transactional leadership style from the possible 5.0 points scale. Second, the mean point of the trust level of the staff to the middle managers was 3.64 points indicating that the directors in general tried to treat the staff of offices/divisions with equitably and to communicate with them openly. Third, the correlation between the trust of followers and several variables showed that the subordinate behavioral characteristics of servant leadership, transformational leadership and transactional leadership had positive effects on the trust. Especially 'individualized consideration' and 'contingent rewards' were highly correlated.

  • This research has been dealt with the nutritional component analysis of two kinds of non-edible marine algae, Sargassum herneri (Turner) C. Ag. and Zostera marina Linne which grow abundantly around the southern coast of Korea, These marine algae were mixed in several kinds of samples rates with the combined feed for poultry sold in the market. These were given to 35 chicken in seven test divisions respectively. We have experimented with 35 chicken grown up for two weeks after hatchout. The combined food for poultry obtained from the market was set up as control divisions. The experiments were as follows: 1) The average weight increase in each test division during feeding (Table 5, Fig.2). 2) Food conversion rate and food efficiency in each test division (Table 7). 3) The comparison of digestive rate of crude protein during feeding (Table 8), The results were as follows: 1) The weight increasing rate of the test animal stock fed the food containing $5\~10\%$ of Sargassum horneri (Turner) C. Ag. powder was higher than the rate of those fed only market food for poultry. 2) The stock given food containing $10\%$ Zostera marine powder showed lower growth than the control divison. 3) No apparent trouble owing to salt component involved in the marine algae was found. 4) The stock given food containing sodium glutaminate and Sargassum horneri (Turner) C. Ag. had better result than that without sodium glutaminate.
