In this research, the soaking and steaming conditions of Korean wheat meju according to the degree of milling were investigated, and the quality characteristic was analyzed, for the manufacture of the standardized Korean wheat meju. As a result of the changes in weight, volume, moisture content, and moisture absorption amount, which indicate the physical properties of Korean wheat meju using 20% polished wheat, 50% polished wheat, whole wheat, and whole wheat flour, most of the wheat materials reached the equilibrium state after 4 hours of soaking. Also, the appropriate steaming time to complete the cooking of the wheat materials was found to be 10 min at $100^{\circ}C$, except for whole wheat. The 20 and 50% polished wheat materials were selected for Korean wheat meju based on the soaking and steaming results. The selected wheat materials were fermented using Aspergillus oryzae and Bacillus subtilis M1, respectively, and the quality properties and enzyme activities showed that A. oryzae would be effective for the manufacture of Korean wheat meju. Also, the 50% polished wheat showed higher total sugar content, reducing sugar content, and ${\alpha}$-amylase activity than the 20% polished wheat. Therefore, it is supposed that the fermentation of 50% polished wheat by A. oryzae would be appropriate for manufacturing superior Korean wheat meju.

The purpose of our study is to confirm the usefulness of our new youth entrepreneurship program. In this study, I suggest design thinking as a new Youth entrepreneurship program which is consist of 9 dimensions: opportunity discovery, opportunity utilization, creativity capacity, career preparation behavior, entrepreneurship, entrepreneurial intention, self-preservation, social problem solving, and educational program objectives. To verify this new program, I conduct a pilot test in middle school and high school; the sample target is randomly selected one class in each school. My main finding is two. First, our new program successfully improves Youth entrepreneurship. Particularly, the improvement of opportunity utilization and entrepreneurial intention are prominent. As reasons, studies about food industry entrepreneurship is an unfamiliar subject for adolescent. Considering that entrepreneurial intention rapidly changes after the experience of entrepreneurial education, researchers need to focus on this variable. Second, I confirm the effects of gender, motivation, prior experience, interest oneself and other's recommendation about the entrepreneurship program. As a result, gender and prior experience do not have an important influence. On the other hand, voluntary interest and other's recommendation are influential. The most important factor is the influence of a teacher. Therefore, researchers need to examine the more specific mechanism of each dimension in the future.

10kW wind turbine has been successfully commissioned at the King Sejong station in April, 2006. The wind turbine installed is a part of the R&D program for developing a solid wind/diesel hybrid power control system for a remote area such as Antarctica. At the same time, the current research aims to develop an anti-icing and de-icing technologies for a small wind turbine rated under 50kW. Since its commissioning, the turbine has generated about 500kWh for 47days without any system faults. Although sufficient data have not been obtained yet, any trouble has not occurred in the wind/diesel hybrid system based on the current analysis. Concerning on the environmental impact by the wind turbine operation, the turbine is installed within the station boundary in order to meet the Madrid protocol. Therefore, wind turbine operation meets the international requirements for preservation of antarctic ecosystem.

1.The domestic waste generated in Iksan city was 177 tons a day last year. 27 tons of that were recycled daily. Due to increased awareness the recycling rate also increased. 2. It is preferred to get continuous publicity and to enforce the program steadily to activate exchange centers and places like a flea market for reusable things, which will lead to increase the life-span of the current designated landfill site. 3. Because burying food waste in underground will be prohibited from year 2005, the reutilization of food waste by feeding domestic animals like ducks and making artificial fertilizer are preferred. 4. The case of Iksan city is expected to be a model to other cities by establishing a display room to accommodate its detail work demonstration, displaying modeled utilization items and exchange center, incinerator, duck ranch, lawn ground, etc. for making a city as an environmental preservation city model.

Many countries have been interested in sustainable development of buildings for environmental preservation. Thus it is significant to assess building envelopes in terms of $CO_2$ emissions owing to Kyoto Protocol. In this paper, a Double Skin Facade(DSF) installed in a general office building was assessed by $CO_2$ emissions(one of the performance-based assessment). To predict $CO_2$ emissions caused by the building energy consumption, the dynamic simulation program(Energy Plus) and $CO_2$ emission factor was used. Because DSF has various airflow regimes, pre-simulation runs were conducted to decide proximate optimal airflow regimes depending on seasonal variation. It is shown that the DSF can achieve 17.1-36.5% of annual energy savings.

This paper presents the implementation of the Blatz-Ko hyperelastic compressible model in a finite element program to deal with large deformation problems. We show analytically and numerically that the minimum number of increment steps in the Newton-Raphson algorithm depends on material properties and applied loads. We also show that this dependence is related to the orientation preservation principle. So we propose a convergence criteria based on the sign of eigenvalues of the deformation gradient matrix.

Purpose: Pathologic tooth migration (PTM) commonly occurs in the anterior region and is associated with periodontal disease. The treatment of PTM of anterior teeth can be complex and time consuming, and a multidisciplinary approach is often required. Materials and Methods: The patient was a 38-year-old woman with a chief complaint of saving and realigning her elongated maxillary left central incisor. This paper describes the successful combined periodontal regenerative (guided tissue regeneration) and prosthetic treatment and a 2-year follow-up of maxillary central incisor with pathologic tooth migration, deep intrabony defect, and poor prognosis. Results: The right maxillary central incisor was restored by laminate veneer and the left by all-ceramic crown. The patient had no pain and discomfort and was satisfied with the outcomes of her treatment for 2 years. She has maintained her recall program at the Department of Periodontology at 3 months interval. Conclusion: The key step in the successful treatment of PTM in anterior region is to obtain a high level of cooperation from the patient. Maintenance of the treatment result of PTM is dependent on the continuous preservation of periodontal health.
