One of the main purposes of universities is to create new intellectual resources that will increase social values. These intellectual resources include academic research papers, lecture notes, patents, and creative ideas produced by both professors and students. However, intellectual resources in universities are often not distributed to the actual users or companies; and moreover, they are not even systematically being managed inside of the universities. Therefore, it is almost impossible for companies to access the knowledge created by university students and professors to utilize them. Thus, the current level of knowledge sharing between universities and industries are very low. This causes a great extravagant with high-quality intellectual and human resources, and it leads to quite an amount of social loss in the modern society. In the 21st century, the creative ideas are the key growth powers for many industries. Many of the globally leading companies such as Fedex, Dell, and Facebook have established their business models based on the innovative ideas created by university students in undergraduate courses. This indicates that the unconventional ideas from young generations can create new growth power for companies and immensely increase social values. Therefore, this paper suggests of a new platform for intellectual properties distribution with university-industry cooperation. The suggested platform distributes intellectual resources of universities to industries. This platform has following characteristics. First, it distributes not only the intellectual resources, but also the human resources associated with the knowledge. Second, it diversifies the types of compensation for utilizing the intellectual properties, which are beneficial for both the university students and companies. For example, it extends the conventional monetary rewards to non-monetary rewards such as influencing on the participating internship programs or job interviews. Third, it suggests of a new knowledge map based on the relationships between key words, so that the various types of intellectual properties can be searched efficiently. In order to design the system platform, we surveyed 120 potential users to obtain the system requirements. First, 50 university students and 30 professors in humanities and social sciences departments were surveyed. We sent queries on what types of intellectual resources they produce per year, how many intellectual resources they produce, if they are willing to distribute their intellectual properties to the industries, and what types of compensations they expect in returns. Secondly, 40 entrepreneurs were surveyed, who are potential consumers of the intellectual properties of universities. We sent queries on what types of intellectual resources they want, what types of compensations they are willing to provide in returns, and what are the main factors they considered to be important when searching for the intellectual properties. The implications of this survey are as follows. First, entrepreneurs are willing to utilize intellectual properties created by both professors and students. They are more interested in creative ideas in universities rather than the academic papers or educational class materials. Second, non-monetary rewards, such as participating internship program or job interview, can be the appropriate types of compensations to replace monetary rewards. The results of the survey showed that majority of the university students were willing to provide their intellectual properties without any monetary rewards to earn the industrial networks with companies. Also, the entrepreneurs were willing to provide non-monetary compensation and hoped to have networks with university students for recruiting. Thus, the non-monetary rewards are mutually beneficial for both sides. Thirdly, classifying intellectual resources of universities based on the academic areas are inappropriate for efficient searching. Also, the various types of intellectual resources cannot be categorized into one standard. This paper suggests of a new platform for the distribution of intellectual materials and human resources, with university-industry cooperation based on these survey results. The suggested platform contains the four major components such as knowledge schema, knowledge map, system interface, and GUI (Graphic User Interface), and it presents the overall system architecture.

The purpose of this study is to evaluate the environmental sustainability of new town development in metropolitan area, Korea and derive some policy implications for sustainable urban development. The case study area selected for empirical research is Jisan Bummul new town in Taegu. In the part of theoretical review, it is considered that the urban form suitable to sustainable development of a metropolis is the type of decentralized concentration. For the decentralized concentration form, we suggest developing suburban centers with self-sufficiency within a metropolis. This strategy is to develop a few suburban centers on the outskirts of a metropolis to decentralize urban activities of the central city, and to conserve the remaining. The empirical study evaluating the environmental sustainability of new town development shows that Jisan Bummul new town generally have low environmental sustain ability, because of the policy of mass housing provisions without consideration on overall natural conditions and environmental capacity of the area. To develop a new town. we must first select the locational site with minimum possibility of the destruction of natural environment, and then it is necessary to develop new towns into compact form to minimize the destruction of the natural environment. Second, a new town should be developed into a large scale to obtain urban self-sufficiency. Third plans must be established for decentralising both industrial and residential functions of a metropolis simultaneously. As more detailed policy implications, it is suggested that the policies are needed to improve the quality of educational conditions and enhance the level of services of public transport facilities. It is also necessary to establish the comprehensive development plan that takes the adjacent developmental area into consideration, and to prepare various action plans to bring up the facilities of self-sufficiency. In the selection of the location of a new town, the adaptability of public transportation planning must be emphasized. But, to take a program for short-term mass housing provisions must be restricted.

This study was carried out to investigate the quality characteristics and antioxidant activity of a functional drink prepared by mixed fermentation of oak mushroom extract and whey. As the ratio of oak mushroom extract increased, the pH value of the whey fermentative solution decreased proportionally, and the titratable acidity increased significantly. The number of lactic acid bacteria after 24 hours of culture was at a level of $10^{11}CFU/mL$ in all whey fermentative solutions containing oak mushroom extracts. DPPH and ABTS radical scavenging activities after 24 hours of culture were higher in a fermentative solution containing oak mushroom extract than in the control. After 24 hours of culture, the nitric oxide production in whey fermentation solution by LPS-induced RAW 264.7 cells was lower compared to that in whey fermentation solution with oak mushroom. Sensory evaluation revealed that, color, flavor, taste, and overall acceptability of the whey fermentation solution sample, which contained 1.0% oak mushroom extract, were much better than those of the other groups. Sensory evaluation of a whey drink containing oak mushroom flavor indicated that the whey drink containing 0.001% oak mushroom flavor was better than the other samples.

Composting animal manure is one of feasible treatments that reserves some portion of nutrients of manure. Although the application of compost to arable land has many advantages, the repeated cultivation of the agriculture land will accumulate the level of heavy metals in the soil which is potentially hamful to people and animals. Therefore it is important to know the characteristics concentration and species of heavy metals in a variety of chemical fonns than just total content of the metal. Because the metals in different forms have different mobilities and bioavailabilites. The aim of this study was to examine the total content and the chemical forms of the heavy metals; Cr, Ni, Cu, Zn, As, Cd and Pb in the animal manure composted with sawdust or rice hull as a bulking agent. A total of 75 compost samples were collected throughout the country and classified into the three groups in accordance with the characteristics of raw materials: swine manure, poultry manure, and mixed(swine + poultry + cattle)manure. The compost samples were analyzed for total metal content and fractionated by sequential chemical extractions to estimate the quantities of metals: exchangeable, adsorbed, organically bound, carbonate and residual. The results showed that the heavy metal concentrations in all compost samples were lower than the maximum acceptable limits by the Korea Compost Quality Standards. The concentrations of heavy metals in the swine manure compost were higher than those of both the poultry and the mixed manure compost except for Cr. Zn and Cu concentrations of three different compost ranged from 157 to 839 mg Zn/kg DM(dry matter) and from 47 to 458 mg Cu/kg DM, depending on the composition of animal manures. The predominant forms for extracted metals were Cr, Ni, Zn, As and Ph, residual; Cu, organic; and Cd, carbonate. The results suggested that the legal standards for composts should be reexamined to revise the criteria on the total metal content as well as metal speciation.

DNA variation of MYL2 intron 5 A345G and ADCYAP1R1 intron 2 A337G were investigated for carcass trait association in finished pigs. Three genotypes(two homozygotes and their heterozygote) were found at 10.6% AA, 45.6% AG and 43.8% GG in MYL2 and 60.5% AA, 34.6% AG, and 22.2% GG for ADCYAP1R1. In finished pig population, individuals containing genotype G- of MYL2 had significantly heavier carcass weight by more than 2.4 kg and thicker backfat thickness by more than 1.3 mm than those of AA homozygous pigs(p<0.05). No significant difference was found in other traits tested in this study such as marbling score, meat color, texture, moisture and separation score(p>0.05). The ADCYAP1R1 intron 2 377GG homozygotes showed coarse texture, i.e., meat quality was inferior than those of AG and AA genotypes, and the moisture level of homozygote AA was higher than those of AG and GG genotypes(p<0.05). The other carcass traits were not significantly associated with ADCYAP1R1 genotypes(p>0.05). The genetic polymorphism of MYL2 and ADCYAP1R1 genes affected the carcass traits in finished pig population. Further studies to explain the association between genetic variations and their phenotypic effects including economic traits in pigs are required including critical mutation in both genes through molecular approaches.

This study was carried out to investigate effects of iron content on the quality of soy sauce, bean paste and red pepper paste, and to elucidate the origin of iron and change of the contents during production processes. For the first step, the iron contents in commercial soy sauce and changes of the contents during brewing process were determined. The results obtained were as follows. 1, Iron contents of raw materials were 108 ppm in soy bean, 133ppm in defatted soy bean, 79 ppm in wheat, 5 ppm in sodium chloride, 58 ppm in seed koji, 300-2000 ppm in spore of Aspergillus oryzae, 240 ppm in wheat gluten, 20 ppm in sodium carbonate (above figures were of dry weight basis), 6 ppm in hydrochloric acid, 18 ppm in caramel and 0.3ppm in brewing water respectively. 2, Iron contents in koji were 200-240 ppm (as dry weight basis) and increased, more or less, in progress of koji-making period. 3. Iron contents in the mashes during fermentation were 40 rpm after 1 month, 43-47 ppm after 3 months and 49-62ppm after 6 months. 4. In chemical soy sauce, the iron content was 159 ppm after hydrolysis of wheat gluten with hydrochloric acid, and 184 ppm after neutralization. 5. Higher iron contents were detected both in fermented and chemical soy sauce when the concentration of total nitrogen increased, but the levels were higher in chemical soy sauce than in fermented one at the same concentration of total nitrogen. 6. In the case of fermented soy sauce, the iron content in the filtrate was decreased by press-filtration, but no significant change was found between before and after heat-sterilization. 7. Iron contents in commercial soy sauce were varied with the producers, however, the average value was 62.7 ppm as calculated as 1.0 percent of total nitrogen. And the average level of iron in home-made soy sauce produced by conventional method was 37.68 ppm.

Unpleasant facilities have been unwelcomed by residents within the region since they are considered to negatively influence the living conditions of the region. Yet recently, a park project within these unpleasant facility areas has begun to improve the negative impression of the region and the satisfaction of local residents has been shown to be very high. Also a park project within unpleasant facilities is found to have significant influence on the community, including resolving conflicts and building mutual friendships among residents by creating pleasant living conditions and improving the quality of life of local residents. The purpose of this study is to investigate how the park project within unpleasant facilities changes the satisfaction level of local residents and affects the sense of community. In order to do so, surveys were given to visitors of Seoul Maru Park, which was turned into a park from a sewage treatment center. According to the analysis result, after the sewage treatment center was recreated as Maru Park, citizen satisfaction was found to be very high. The sense of community that the visitors feel was found to be high in general, but the 'sense of connection and neighbor bonds' turned out to be lower compared to the 'sense of settlement and belonging.' A regression analysis was performed to determine the relative influence of visitor satisfaction on the sense of community. As a result, in the division of 'sense of settlement and belonging,' the satisfaction with ecological health was affected the most, followed by satisfaction with scenic beauty, whereas satisfaction with cleanness had no influence. In the division of 'sense of connection and neighbor bond,' none of the satisfaction with cleanness, ecological health and scenic beauty showed any influence in the analysis. According to the above result, a park project within unpleasant facilities brings a positive influence on the 'sense of settlement and belonging,' yet in order to improve the 'sense of connection and neighbor bond,' which is not influenced by the project, the adequate facilities and activity programs are considered to be necessary to change the residents' of sense of community.

This study investigated the rate of setup variance by the rotating unbalance of gantry in image-guided radiation therapy. The equipments used linear accelerator(Elekta Synergy TM, UK) and a three-dimensional volume imaging mode(3D Volume View) in cone beam computed tomography(CBCT) system. 2D images obtained by rotating $360^{\circ}$and $180^{\circ}$ were reconstructed to 3D image. Catpan503 phantom and homogeneous phantom were used to measure the setup errors. Ball-bearing phantom was used to check the rotation axis of the CBCT. The volume image from CBCT using Catphan503 phantom and homogeneous phantom were analyzed and compared to images from conventional CT in the six dimensional view(X, Y, Z, Roll, Pitch, and Yaw). The variance ratio of setup error were difference in X 0.6 mm, Y 0.5 mm Z 0.5 mm when the gantry rotated $360^{\circ}$ in orthogonal coordinate. whereas rotated $180^{\circ}$, the error measured 0.9 mm, 0.2 mm, 0.3 mm in X, Y, Z respectively. In the rotating coordinates, the more increased the rotating unbalance, the more raised average ratio of setup errors. The resolution of CBCT images showed 2 level of difference in the table recommended. CBCT had a good agreement compared to each recommended values which is the mechanical safety, geometry accuracy and image quality. The rotating unbalance of gentry vary hardly in orthogonal coordinate. However, in rotating coordinate of gantry exceeded the ${\pm}1^{\circ}$ of recommended value. Therefore, when we do sophisticated radiation therapy six dimensional correction is needed.

Forest covers 30% of the Earth's land area and plays an important role in global carbon flux through its ability to store much greater amounts of carbon than other terrestrial ecosystems. The Gross Primary Production (GPP) represents the productivity of forest ecosystems according to climate change and its effect on the phenology, health, and carbon cycle. In this study, we estimated the daily GPP for a forest ecosystem using remote-sensed data from Moderate Resolution Imaging Spectroradiometer (MODIS) and machine learning algorithms Support Vector Machine (SVM). MODIS products were employed to train the SVM model from 75% to 80% data of the total study period and validated using eddy covariance measurement (EC) data at the six flux tower sites. We also compare the GPP derived from EC and MODIS (MYD17). The MODIS products made use of two data sets: one for Processed MODIS that included calculated by combined products (e.g., Vapor Pressure Deficit), another one for Unprocessed MODIS that used MODIS products without any combined calculation. Statistical analyses, including Pearson correlation coefficient (R), mean squared error (MSE), and root mean square error (RMSE) were used to evaluate the outcomes of the model. In general, the SVM model trained by the Unprocessed MODIS (R = 0.77 - 0.94, p < 0.001) derived from the multi-sites outperformed those trained at a single-site (R = 0.75 - 0.95, p < 0.001). These results show better performance trained by the data including various events and suggest the possibility of using remote-sensed data without complex processes to estimate GPP such as non-stationary ecological processes.

This study was conducted to compare nutritional composition and taste-related compounds of breast and thigh meats from four lines of Korean native chickens (KNC) Yeonsan Ogye, Hyunin Black, Hwangbong, and Hoengseong Yakdak. White Leghorn (WL) was used as a control. Fifteen male chickens (three chickens in each line) were grown under same condition and slaughtered at 53 weeks old. The contents of Fe and K in KNC, especially Hwangbong breast meat and thigh meat of Hyunin Black and Hoengseong Yakdak, were higher than WL. The contents of Na were lower in KNC compared with WL regardless of parts (p<0.05). Vitamin A contents were higher in thigh meat of WL and Hyunin Black, and vitamin $B_1$ contents were lower in Hoengseong Yakdak than other lines. Vitamin $B_3$ were higher in breast meat of four lines of KNC and thigh meat of Hoengseong Yakdak than WL. Total amino acid contents were higher in breast meat of KNC than WL. The level of good-tasting amino acids were significantly higher in breast meat of Hoengseong Yakdak and WL, and thigh meat of Hyunin Black and WL than other lines of chickens (p<0.05). The ratio of good-tasting amino acids to bitter tasting amino acids was higher in breast meat of Hoengseong Yakdak and thigh meat of Hyunin Black than WL. IMP contents were higher in Hyunin Black and WL than other lines of chickens. Based on these results, it can be concluded that four lines of KNC may have superior nutritional quality and taste when compared with WL.
