Despite great commercial interest, relatively little has been described about molecular mechanism of bivalve reproduction. We investigated genes involved in ovarian maturation of the Yesso scallop, Patinopecten yessoensis. GSI index and histological analysis revealed that maturation of ovary begin in February and spawning period is from April to June which is similar to the previous study in the East Sea. As result of combination analysis of differential display RTPCR (DDRT-PCR) and histological examination, vitellogenin (Vg), ferritin (Ft) and ADT/ATP carrier protein (ACC) were identified as differently expressed genes in maturating ovary. Endpoint RT-PCR results showed that Vg is ovary-specific genes whereas Ft and ACC are expressed ubiquitously suggesting that Vg can be good molecular markers for ovarian development and sex determination in bivalves. Quantitative PCR results revealed that Vg were expressed highest during growth stage and appears to play a major role in oocyte maturation. On the contrary, expression of Ft was highest after spawning stage, which suggests that up-regulation may be involved in spawning and inactive stages in which the scallops recover from spawning. In addition, high level of the mitochondrial gene, ACC, may play a role in energy metabolism in maturating oocytes. Isolation and molecular studies of these key genes will expand our knowledge of the physiological changes from various exogenous factors including temperature, salinity, pH, even or numerous endocrine disrupting chemicals (EDCs) during reproductive cycle. In addition, further study of these genes implicates various industrial applications including the stable seed production, increased food quality, or economic aquaculture system.

The importance of cultural contents industry is steadily growing owing to the Korean wave etc. and Buddhist cultural contents is a part of the cultural contents. However, the development of Buddhist cultural contents in many ways has left much to be desired. That is because, it is difficult for the public, who is not Buddhist scholar, to understand and take interest in conventional contents on Buddhist books themselves which are digitalized. Also, most contents researches are discussed on the necessity of contents development and just stay in these subjects, but it is insufficient to study a semantic analysis and visualizing contents on Buddhist books. So, in this paper, we analyse mandala's twinning rite in the Buddhist books and implement visual contents on the rite. The mandala is using toohadeokbul in a special way as the abhisinca rite. We analyse concept of the toohadeokbul and implement its visual contents which visualize ideological logic of Buddhism. The implemented contents are able to provide the public with Buddhist cultural experience of the yard. Additional, by trying to visualize descriptive expressions of Buddhist books, this paper could be a precedent for developing visual contents of unlimited data comprised in Buddhist books.

Being called 'the period of diversity', the 21st century is taking on a new aspect which is different from the past where a certain phenomenon of a specific area was prescribed as one representative icon of a period. In particular, the globalization culture acted as the catalyst to accept such diversity and it appeared as a new culture code, 'fusion' throughout society and culture. Especially, unlike two-hour movies, the recent drama $\lceil$Gung$\rfloor$ showed various fusion style costume over a period of three months and created a sensation of fusion style costume. Therefore, this study is aimed at investigating fusion style costume by selecting the TV drama $\lceil$Gung$\rfloor$ which was on the air in 2006. Though various studies on fusion style costume, which is becoming a new culture code, have been conducted, this study is meaningful in that it's time to conduct a new study through a popular TV drama. Based on preceding studies on fusion style, the elements of fusion style were analyzed by capturing the most frequently exposed heroine's costume, and new design development introducing fusion elements was attempted for empirical studies. The study results are as follows. First, it was found that the fusion trend is a culture code which already spread to the public and is shown in the fashion in various ways. Second, the drama $\lceil$Gung$\rfloor$, is commented as a new dram which introduced the fusion style costume into Korea through a modern version of constitutional monarchy and is commented as a medium which created an interest in the fusion costume among the public as well. Third, new trend elements of the fusion style could be derived through empirical studies by design development.

As the globalization has increasingly brought in the disintrgration of boundary between cultures, the hybrid of styles, or fusion styles in various cultural spheres have been introduced as important theme. With this new trend, the traditional culture of Asia appeared as the source of inspiration for the West, and as the source of enhanced pride and asset for ethnic groups which have been considered "the Other" by the West. 1990's witnessed a drastically increased interest in Orientalism and Ethnic trends in most social aspects, especially in culture and art. They have been the main theme in fashion, providing the source of inspiration with elements such as the unique color schemes, composition methods and geometrical simplicity. The creative application of traditional culture into modern design as well as fashion can make a significant contribution and be a solid foundation for the development of national culture in general, since images containing cultural authenticity are the visual representation of the nation and they can be important tools for the globalization of design. This study aims to find out the formative characteristics of Korean traditional embroidery and the ways they are applied in modern fashion by world-renowned Korean fashion designers. The purpose of this study is to make a fundamental source for further study by the same author on creative design development utilizing the result. The study methods are literature study combined with research of genuine articles from museums and personal ownership as well as photos from magazines and internet. The significance of this study lies in enhancing the appreciation of Korean traditional culture and expanding the possibility of its globalization by modern application.

We analyzed the current research trends of living modified organisms (LMO) by questionnaires in the interest of making biosaftey laws and policies in Korea. We executed a pre-survey at the Crop Functional Genomics 2004 conference and obtained LMO research information from 423 LMO research organizations, including 32 national research institutes, 314 universities, and 77 industries. We found that the total 59 kinds of hosts including 26 kinds of plants, 15 kinds of animals, and 18 kinds of microbes were used for LMO research and E. coli was the most common host. The risk of the most experimental hosts was below a biosafety level of 1 (73.8%) and 2 (25.9%). LMO development use purpose was implemented in various developmental uses: 51.3% in test and research use, 19% in health and medical use, and 12.9% in agriculture use. The experiment product, waste product, and products of host for LMO development were 327.2, 223.6, and 13.5 in number of plants; 280.6, 52.4, and 8.7 in number of animals; and $8.3\;{\times}\;10^{11}CFU$, $7.7\;{\times}\;10^{11}CFU$, and $6.5\;{\times}\;10^{11}CFU$ in microbes in 2004. The survey results about how to possess the LMO were very unreliable, because only 10.6% of the researchers returned the questionnaires. Consequently, we strongly suggest the scientific organizations as well as scientists should have more interests in biosafety of LMO research and an LMO biosafety management system should be developed for Korea's future biotechnology.

The purpose of this study was to analyze Hanwoo usage in restaurants and to develop menus of lean cut Hanwoo. Restaurant served customers Hanwoo menus, with the exception of broiled or roasted meat, mainly to provide various menus to customers (4.14), due to customer needs (3.87) and utilizing stocks (3.59). On the other hand, the reason for not providing Hanwoo menus, with the exception of broiled or roasted meat was manpower shortage (3.63), lack of popularity (3.58), low profit (3.29), preservation of Hanwoos' original flavors (3.28) and complex cooking methods (3.22). Concomitantly, the restaurant owners' intentions to apply new menus with lean cut Hanwoo was 73.4%, showing an interest in developing new menus and recipes using lean cut Hanwoo suitable to the changing owner awareness of customer health and trends. This study has established a standard for developing cooking methods and developed menus according to classified recipes for lean cut Hanwoo, based on the survey of restaurants' current status of using Hanwoo and the owners' opinions. 20 menus using lean cut Hanwoo (rump or shank) were developed by $1^{st}$ and $2^{nd}$ cooking experiments, and in-depth interview of experts-groups. Of these, 12 menus suitable for the restaurant were finally selected based on the results of consumer's evaluation using JARS. Structured recipe flow diagram and recipe instructions were developed for future semi-processed or processing foods. Diverse recipe methods using lean cut Hanwoo were obtained from the study, however aggressive public relations work is required for promoting the developed menus.

Aeronautics engine cooling is one of the biggest problems that engineers have tried to solve since the beginning of human flight. Systems like radiators should solve this purpose and they have been studied extensively and various solutions have been found to aid the heat dissipation in the engine zone. Special interest has been given to air coolers in order to guide the air flow on engine and lower the high temperatures achieved by the engine in flow conditions. The aircraft companies need faster and faster tools to design their solutions so the development of tools that allow to quickly assess the effectiveness of an cooling system is appreciated. This paper tries to develop a methodology capable of providing such support to companies by means of some application examples. In this work the development of a new methodology for the analysis and the design of oil cooling systems for aerospace applications is presented. The aim is to speed up the simulation of the oil cooling devices in different operative conditions in order to establish the effectiveness and the critical aspects of these devices. Steady turbulent flow simulations are carried out considering the air as ideal-gas with a constant-averaged specific heat. The heat exchanger is simulated using porous media models. The numerical model is first tested on Piaggio P180 considering the pressure losses and temperature increases within the heat exchanger in the several operative data available for this device. In particular, thermal power transferred to cooling air is assumed equal to that nominal of real heat exchanger and the pressure losses are reproduced setting the viscous and internal resistance coefficients of the porous media numerical model. To account for turbulence, the k-${\omega}$ SST model is considered with Low- Re correction enabled. Some applications are then shown for this methodology while final results are shown in terms of pressure, temperature contours and streamlines.

Recently, as location-determination of indoor users is available with the development of variety of localization techniques for indoor location-based service, diverse indoor location based services are proposed. Accordingly, it is necessary to develop individualized POI recommendation service for recommending most interested points of large-scale commercial spaces such as shopping malls and departments. For POI recommendation, it is necessary to study the method for exploring location which users are interested in location with considering user's mobility in large-scale commercial spaces. In this paper, we proposed POI recommendation system with the definition of users' as 'Stay point' in order to consider users' various interest locations. By using the proposed algorithm, we analysis users' Stay points, then mining the users' visiting pattern to finished the proposed. POI Recommendation System. The proposed system decreased data more dramatically than that of using user's entire mobility data and usage of memory.
