The purpose of this study was to develop the entrepreneurial mentoring scale on start-up mentoring situation. In recent years, as the needs for entrepreneurship have grown from domestic to foreign, entrepreneurship education is actively being carried out. The entrepreneurial mentoring is strengthening its weight and contents in entrepreneurship education. However, research on the mentoring function scale designed to reflect the characteristics of entrepreneurial mentoring is rarely performed in Korea. In this study, we conducted a qualitative and quantitative research to achieve the research goal. First, we derive the entrepreneurial mentoring scales through literature review and expert group discussions, and we conducted the empirical analysis to draw conclusions. The results of this study are as follows. In the first step, literature review was conducted. In the second step, four major factors and questionnaires were derived through expert group discussion. In the third step, the doctoral level specialists developed 16 questionnaire items to measure the four factors of entrepreneurial mentoring derived from the second step and verified the content validity and the facial validity in fourth step. As a result of this survey, we conducted questionnaires on founding mentors who belonged to 17 Creation Economic Innovation Centers nationwide (153) and analyzed the problem solving, networking, communication, and motivation formation through exploratory factor analysis. This questionnaire was used to survey the entrepreneurial mentors who belonged to the 17 Center for Creative Economy and Innovation under the Ministry of Science, ICT & Future Planning of South Korea(153). In fifth step, as the results of factor analysis such as EFA and CFA, we could confirm four factors including problem solving, networking, communication, and motivation. The significance of this study is as follows. First, academic significance was the first study of the entrepreneurial mentoring function scale reflecting the characteristics of entrepreneur mentoring as a qualitative and quantitative approach in Korea. Second, it is hoped that practitioners will be able to better measure the mentoring function of entrepreneurial mentors and contribute to improving the quality of future entrepreneurial mentoring programs.

Objectives: This study was to examine HIV/AIDS knowledge of transmission, attitudes toward homosexuals on stigma of HIV/AIDS and discriminatory attitudes towards person with HIV/AIDS (PWHAs) by middle and high school students in Seoul, Korea. Methods: The population of this study is middle and high school students in Seoul, Korea. Eight junior high schools and eight senior high schools were selected randomly. Three thousand and one hundred thirty-one students (1704 males and 1397 males) from 16 schools participated in the survey, and 2.977 cases were analyzed. A self-administered questionnaire measuring socio-demographic variables, HIV/AIDS knowledge of transmission, sigma of HIV/AIDS (3 items, 5-point Likert-type scale) and discriminatory attitudes PWHAs (5 items, 5-point Likert-type scale) was utilized. The Structural Equation Modeling was employed to investigate the research Model. Results: The empirical study shows that a number of statistical hypotheses are significant. The stigma and discriminatory attitudes PWHAs were significantly different by middle and high school students. The attitudes toward homosexuals and HIV/AIDS knowledge of transmission were important factors on stigma and discriminatory attitudes PWHAs. Socio-demographical variables such as sex was related to the stigma and discriminatory attitudes PWHAs. Conclusion: Therefore, it is important to design HIV prevention strategies that increase in positive attitudes towards PWHAs.

The purpose of this study is to analyze the change of environmental capacity in Yong-in City, Gyeonggi-do, South Korea through calculation of ecological footprint indices and analysis of their changes, and to suggest implications for urban development and planning. In this study, we analyzed ecological footprints of 1993, 2003, and 2013 to understand the patterns of land use changes and development in Yong-in City. We also compared the GIS land cover maps and ecological footprint indices to figure out land cover changes associated with resource consumption in Yong-in City. As a result, we found the following three lessons. First, the ecological footprint indices of Yong-in City are 3.20(gha) in 1993, 6.50(gha) in 2003, and 11.15(gha) in 2013. This implies that the ecological footprint of Yong-in City is much larger than 1.80(gha), the globally required ecological footprint per capita and 3.56(gha), the average ecological footprint of South Korea. Second, the forest ecological footprint of Yong-in City was calculated as the largest, followed by the ecological footprints of energy, food, and built environment. In particular, the forest ecological footprint was the most rapidly increased from 0.002(gha) in 1993 to 7.32(gha) in 2013, followed by energy ecological footprint from 0.87(gha) to 2.38(gha). This implies that the provision and consumption of timber are seriously unbalanced, and energy consumption is unsustainable because of the rapid increase of residential and commercial land development in the city. Third, our analysis of the rapid increase of forest ecological footprint indicates that the disturbed forest areas are concentrated in the increased built environment areas. We also observed that the increase of energy ecological footprint indices was caused largely by the increase of the commercial and road areas. This implies that Yong-in City should minimize forest disturbance and expand green areas for future in the city. In addition, this may provide a reasonable ground that the city should reduce the use of fossil fuels and facilitate the use of renewable energy.

Unlike in analog display devices, the physical screen resolution in digital devices are fixed from the manufacturing. It is a weak point on digital devices. The screen resolution displayed in digital display devices is varied. Thus, interpolation or decimation of the resolution on the display is needed to make the input pixels equal to the screen resolution., This process is called image scaling. Many researches have been developed to reduce the hardware cost and distortion of the image of image scaling algorithm. In this paper, we proposed a Winscale algorithm. which modifies the scale up/down in continuous domain to the scale up/down in discrete domain. Thus, the algorithm is suitable to digital display devices. Hardware implementation of the image scaler is performed using Verilog XL and chip is fabricated in a 0.5${\mu}{\textrm}{m}$ Samsung SOG technology. The hardware costs as well as the scalabilities are compared with the conventional image scaling algorithms that are used in other software. This Winscale algorithm is proved more scalable than other image-scaling algorithm, which has similar H/W cost. This image-scaling algorithm can be used in various digital display devices that need image scaling process.

This study was carried out to investigate the quality characteristics of brands pork: a crossbred between Korean native and wild pigs (Y), a commercial LYD breed fed with probiotics (J), and a commercial LYD fea without probiotics (M). The moisture and crude ash content of Y treated pork was higher than those for J and M brands, but the crude fat content of J pork was significantly lower (p<0.05) than Y and M brands. The moisture and crude fat contents of Y gilts were higher (p<0.05) than those of barrows. The pH values of Y gilts were higher (p<0.05) than those of gilts of J and M brands. The Land W values of Y pork were lower (p<0.05) than with J and M brands. The springiness value of J pork was significantly higher (p<0.05) than Y and M porks. The sensory scores of Y pork were higher than pork of J and M. The juiciness of gilts of M brands was higher (p<0.05) than for barrows. With regard to the fatty acid profiles among the pork loins, linoleic and arachidonic acid contents of Y pork were higher than with J and M, while the palmitic, pamitoleic, stearic, and oleic acid contents were lower. The saturated fatty acid (SFA) content of Y pork was lower than that for J and M ones, while the unsaturated fatty acids (USFA), essential fatty acids (FFA), USF/ASF A ratio, FFA/SFA ratio, and EFA/USFA ratio were higher. The stearic acid content of M barrows was higher (p<0.05) than that for gilts.

As the previous paper of studios on lipids in fresh-water fishes, the present study was designed and analyzed to investigate the distribution of lipid components in various tissues of snake head, Channa argus. The free lipid was consisted of neutral lipid ($66.6{\sim}72.4\%$), phospholipid($17.9{\sim}20.4\%$) and glycolipid ($5.7{\sim}12.2\%$), while the bound lipid was consisted of phospholipid($28.6{\sim}50.6\%$), neutral lipid($13.2{\sim}36.1\%$) and glycolipid($3.8{\sim}22.8\%$). The neutral lipid was mainly consisted of triglyceride($62.00{\sim}90.20\%$) in free lipid, and esterified sterol & hydrocarbon($51.30{\sim}72.70\%$) in bound lipid. The phospholipid was mainly consisted of phosphatidyl ethanolamine($28.96{\sim}42.75\%$) and phosphatidyl choline ($27.85{\sim}41.06\%$) in free lipid, and phosphatidyl choline($47.18{\sim}52.45\%$) and phosphatidyl ethanolamine ($17.88{\sim}26.67\%$) in bound lipid. The major fatty acids of polar lipid in free and bound lipids were $C_{16:0}(21.03\%,\;22.62\%),\;C_{16:1}(8.70\%,\;30.1\%),\;C_{18:1}(20.62\%,\;12.11\%),\;C_{22:5}(3.21\%,\;6.50\%)\;and\;C_{22:6}(7.56\%,\;16.02\%)$, and these of neutral lipid in free and bound lipids were $C_{16:0}(18.98\%,\;19.12\%),\;C_{16:1}(9.04\%,\;13.49\%),\;C_{18:1}(22.94\%,\;11.61\%)\;and\;C_{22:5}(3.00\%,\;10.05\%)$, respectively. The unsaturation(TUFA/TSFA) of bound lipid was 3.99, and 2.5 times higher than 1.43 of free lipid. The contents of total essential fatty acid in free lipid were ranged $7.99\%\;to\;14.69\%$, and slightly higher than $6.57\%\;to\;8.25\%$ of bound lipid. In both polar and nonpolar lipids, w3 highly unsaturated fatty acid(w3-HUFA) contents of bound lipid were ranged $22.57\%\;to\;31.83\%$, and $2{\sim}3$ times higher than $7.88\%\;to\;14.03\%$ of free lipid. There were significant difference between the lipid and its fatty acid composition in free and bound lipids and/or in various tissues.
