In relation to shortening generation by using embryo culture of barley immature seed, it is important to find out profitable embryo age for embryo culture and to understand the relationship among embryo and other characters. Two varieties(Olbori and Dusan #12) were cultivated under two growth conditions(15/10 and 25/15$^{\circ}C$). The embryos were aseptically excised when immature seeds were collected 9, 13, 17, 21, 25 and 29 days after heading and cultured on $B_5$ medium. On the 21st day after heading, the length of embryos from top or middle part of spike was longer than that from bottom part. Embryos from bottom part under low temperature condition had the shortest length. Shoot length, root length and root number after embryo culture were little difference among three parts of spike under high temperature condition. Under low temperature, seedlings from bottom part of spike were inferior to those from top or middle part. Length of 29-day-old embryos under low temperature condition was similar to that of 17-day-old ones under high. Under high temperature condition, the length of 17-day-old embryo had positive correlation with kernel width, shoot length, root length and root number, but that of 21-day-old one didn't have. Seventeen-day-old embryos obtained from 25/15$^{\circ}C$ growth condition seem to be efficient to shortening generation by using embryo culture.

To prevent weakly flocculating characters of bottom brewing yeast during first fermentation, various technical investigations were carried out using strain of Saccharomyces cerevisiae. It appeared that the propagation at $10^{\circ}C$ promoted the molecular structure and biochemical composition of cell wall in favor of flocculation. The yeast grown at $20^{\circ}C$ by addition of zinc ion also had a stimulating effect on flocculation behavior during first fermentation cycle. The zinc ion did not influence directly on the changes of cell wall in favor of stronger flocculence. The increased fermentation activity of yeast due to addition zinc ion was rather responsible for the intensified flocculation capacity. It was concluded that the weakly flocculating characters of bottom brewing yeast during first fermentation can be solved by using yeast propagated at $10^{\circ}C$ or by means of yeast by addition of zinc ion during propagation.

Baekje patterned Pyojihwajomoonkeum is a fabric that expresses Baekje's unique culture possessed by Shosoin(正倉院) in Japan. Reflecting the close exchange relationship with the Chinese Southern Dynasties, these patterns are suitable as good examples to grasp the forms and atmosphere that prevailed during that era. Through the analysis of many pieces, it has been identified that the patterns were unique to Baekje. With an aim to ascertain and restore the original form of Pyojihwajomoonkeum, designs were proposed utilizing Pyojihwajomoonkeum as a form of storyteller clothing that fits the modern sense. Fabric was designed by continuously repeating the colors and patterns of Pyojihwajomoonkeum upward, downward, leftward, and rightward and woven with a Jacquard loom. The fabric woven was dried, processed, and used to make a total of four pieces of storyteller clothing consisting of men's wear, comprising a jeogori and pants, and women's wear comprising a jeogori and skirt. The top jacket was long enough that the hip is covered. It has wide sleeves and linear decorations were attached to the collar, lower edge of sleeve, and bottom hem. The pants are wide legged, the top is wide, and the bottom hem had linear decorations attached. What is the most important when using the original form of a traditional culture is processing the raw materials following cultural traditions to create value. Costumes of an era are the combination of individual elements and represent the culture of that era. Therefore, a consideration of the origin and prevailing ideas of the era must be considered. It is anticipated that this paper will serve as a basis for leading such a process, followed by studies on the utilization of the original form of Baekje culture.

We investigated the growth performance of oysters (initial shell height $57.5{\pm}8.5$ mm) under differing conditions of tidal exposure time and culture rack height in an experiment that commenced in April, 2011. Significant differences were observed in shell height from June 2011, in total weight from August, and in meat weight from September. Fatness tended to decrease during the experimental period, but was not significantly different at the end of the experiment. Significant differences in survival rates were mainly observed from June to August. After September, further changes were not observed in any experimental treatment group. The greatest growth potential ($L_{\infty}$) and survival rate were observed at a sea level of approximately 116 cm. The results indicate that in the study area the use of oyster culture conditions involving 1 or 2 h of tidal exposure and 60 - 70 cm rack height could result in oysters reaching the favored commercial half shell size within 14 months, with > 80% survival.

The present study examined postmetacercarial changes in the excysted metacercariae of Echinostoma caproni maintained in the defined medium Mixture 199 plus 20% calf serum for 7 days at $41^{\circ}C$. The gas phase was atmospheric air. Each culture was inoculated with 25 excysted metacerariae. Cultures were maintained upright in closed 15 ml plastic centrifuge tubes each containing 10 ml of medium plus 200 units of penicillin/ml and $200{\;}\mu\textrm{g}$ of streptomycin/ml. By 4 days in culture, most metacercariae had voided their excretory concretions. Organisms were clumped or solitary at the bottom of the cultures. Many organisms showed flaring of the oral collar and extension of both the collar and tegumentary spines. By 4 days in culture, posterior protuberances or bumps were noted on many of the organisms and some organisms showed abnormal vesicular growths or blebs at their posterior ends. Some mortality was noted in culture by day 5, but most organisms were still alive when the cultures were terminated on day 7.

The method of yeast propagation has an influence on yeast physiology, fermentation ability, flocculation rate, and taste stability of beer. In order to find optimal conditions for propagation, several parameters were investigated in combinations. The bottom brewing yeast grown at $10^{\circ}C$ indicated that a higher flocculation capacity during the $1^{st}$ fermentation. However, the taste stability and the aroma profile were not affected by parameters of propagation investigated. The beer quality was rather affected by storage duration. In addition, a correlation between tasting and chemiluminescence was found at the beer, which was produced using bottom brewing yeast. The propagation at $10-25^{\circ}C$ with addition of zinc ion indicated the best condition to improve fermentation ability, flocculation rate, and filterability for bottom brewing yeast, whereas the propagation at $30^{\circ}C$ with addition of zinc ion showed the best condition to increase fermentation ability for top brewing yeasts.

Growth of researches addressing cross-culture in international business is exponential. This article reviews the extant researches around the national culture and describes the various conceptualization of culture through discussion of some of popular models of national culture. This article presented some of the most important issues in international business surrounding globalization, especially convergence and divergence of cultures and cultural changes. Global rapid changes in international business environment request the reconsideration of the assumption of cultural stability and the simple view of culture, which tends to examine the static influence of a few cultural factors in isolation form other cultural factors and contextual elements. This paper identifies a valid cultural grouping and proposes the following typology of the possible methodologies in international business; Ethnological description, Use of proxies, Direct values inference, and Indirect values inference. Rather than selecting a single methodology, it appears to be more appropriate to use multi-method in the cross-cultural international business research. It has been shown that cultural change is intertwined with socioeconomic-institutional variables, and that these variables may also add to determine culture contemporarily. This paper also explained the dynamics of culture as multi-level, multi-layer constructs. According to this model, we may understand how the dynamic nature of culture conveys the top-down-bottom-up processes where one cultural level affects changes in other level of culture.

In our culture, the term, "be like", is frequently used. There are expressions such as "feminine-looking dress" and "manly style" relating to this term when we describe the styles of clothing. This study addresses the question on which type of garment would be selected under the description of the term, "be-like", in relation to gender. This term reveals the preconception of gender as being feminine or masculine according to the styles and colors of clothes. A group of 362 college students from Seoul and Gyeonggi area was surveyed fur the study The statistical analysis of SPSS 10.0 was applied f3r analyzing the data, and the significant variances were reviewed by the basic statistics, multi-variate and T-test. The results are as follows: First, the details of clothes imply the preconceived idea of gender. As a result, women's blouses and skirts were selected as the most feminine upper and bottom garments. The Y-shirt and T-shirt were selected as the most masculine upper garments. However, in contrast to the . skirts being the most feminine bottom wear, the pants were not significantly recognized as the most masculine ,clothes. Second, the variances of the survey show that the female students are more conscious of the sexual identity expressed in clothes than the male students. Third, the styles of clothes reflect the general understanding of what is considered to be "feminine or not feminine" and "masculine or not masculine" In conclusion, this study has discovered that the certain characteristics of gender are predominantly implicated in the styles length, and color of clothes. Both men and women responded differently in defining their idea of "femininity" and "masculinity". Nevertheless, there still exists strong preconception of what is considered to be feminine or masculine, and it affects the choices people make in selecting clothes.

Climate change and global warming are the biggest challenges of the current generation. Every industry has contributed to the climate change and global warming. Even the apparel industry cannot avoid the criticism regarding fast fashion and its contribution to the pollution. The transition to the decarbonized economy is in progress. All aspects of business functions are influenced by climate change. Sustainable development and climate change are closely linked, and business plays the key role in addressing and finding solutions to the challenges of climate change. Luxury brands are the trendsetters and tastemakers. They are the leaders in the fashion industry and therefore responsible for improving on sustainability as well. Even luxury business cannot avoid environmental issues. The relation between luxury and sustainability is explored with the Burberry case based on the Triple Bottom Line (TBL) framework. There are various ways for luxury brands to excel in sustainability and affect other companies' practices. The companies can incorporate the concept of sustainability in their brand stories as part of the branding process. They can also improve demand planning accuracy and produce upcycled goods. Centering on Burberry's case, this paper aims to explore the current sustainable practices of luxury business along with its future direction toward sustainable development. Its contribution and directions for both researchers and business practitioners are discussed.
