The purpose of this study includes: the relationships between corporate entrepreneurship(innovation, proactiveness, risk-taking) and firm performance(non-financial performance, financial performance) and the mediating effect of the self-efficacy on the relationship between corporate entrepreneurship and firm performance. In order to verify the relationships and mediating effect, data were collected from 368 individuals in employees working in small and medium-sized firms at Gyeongnam region to test theoretical model and its hypotheses. All data collected from the survey were analyzed using with SPSS 18.0. This study reports findings as follows: first, the relationship between the corporate entrepreneurship(except innovation) and the employee's self-efficacy is positively related. Second, there was also a positive correlation between the employee's self-efficacy and firm performance. Third, the relationship between the corporate entrepreneurship and the non-financial performance is positively related. The relationship between the corporate entrepreneurship(except innovation) and the financial performance is positively related. Finally, the employee's self-efficacy played as a partial mediator on the relationship between risk-taking and firm performance. The employee's self-efficacy played as a fully mediator on the relationship between proactiveness and non-financial performance. The employee's self-efficacy played as a partial mediator on the relationship between proactiveness and financial performance. However, there was no empirical evidence for the mediating effect of employee's self-efficacy on the relationship innovation and firm performance. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.

In order to improve the urban thermal environment, efforts are being made to increase green areas in cities that include park construction, planting, and green roofing. Among these efforts, urban parks play an important role not only in improving the urban thermal environment, but also in terms of ecosystem services (serving as resting places for citizens, providing cleaner air quality, reducing noise, etc.). Therefore, the purpose of this study is to suggest planning and management guidelines for urban parks that are effective in improving the thermal environment, by analyzing the urban surface temperature reduction performance of urban parks. To do this, first, land surface temperature was calculated by using Landsat 8 images. Second, the PCI (Park Cool Island) index was calculated to identify the temperature reduction performance of urban parks. Third, the characteristics of parks (area, shape, vegetation) and the surrounding spatial characteristics (land cover, building-related variables, etc.) were identified. Finally, the relationship between the PCI indices (PCI scale, PCI effect, PCI intensity) and the characteristics of the parks and their surroundings were analyzed. The results revealed that the parks consisting of a larger area, simple shape, and higher tree coverage ratio had increased PCI performance, and were advantageous for improving the urban thermal environment. Meanwhile, PCI performance was found to have decreased in areas with a higher impermeable area ratio and building coverage ratio. The outcomes of this study can be used to identify priority areas for planning and management of urban parks and can also be utilized as planning and management guidelines for improving urban thermal environment.

The effects of microorganisms inoculated in beef, pork and chicken on the production of various biogenic amines (BA) were examined. Acinetobacter haemolyticus, Aeromonas hydrophila subsp. hydrophila, Alcaligenes faecalis subsp. faecalis, Bacillus cereus, Bacillus subtilis, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Lactobacillus alimentarius, Lactobacillus curvatus, Leuconostoc mesenteroides subsp. Mesenteroides, Proteus mirabilis, Proteus vulgaris, Pseudomonas aerugina, Salmonella enteritidis and Salmonella typhimurium were inoculated into beef, pork and chicken and incubated for 24 h at optimum temperatures of each bacterium. In ground beef, total amount of amines (TAA) produced was highest in the sample inoculated with Bacillus cereus, followed by Enterobacter cloacae. In ground pork, TAA was highest in the sample inoculated with Alcaligenes faecalis, followed by Enterobacter cloacae, Proteus vulgaris and Bacillus cereus. TAA of chicken breast was highest in the sample inoculated with Alcaligenes faecalis, followed by Bacillus cereus and Lactobacillus alimentarius while in chicken leg was the sample inoculated with Proteus vulgaris, followed by Enterobacter aerogenes, Enterobacter cloacae and Alcaligenes faecalis. Among biogenic amines produced, cadaverine (CAD) was detected at the highest level, followed by putrescine (PUT) and tyramine (TYM), their order being reversed by the kind of microorganism in beef and pork. In chicken breast and leg, CAD level was still the highest but PUT, TYM or PHM was the second highest, depending upon the kind of microorganism inoculated. In total, Alcaligenes faecalis, Enterobacter cloacae and Bacillus cereus were ones that produced a larger amount of BAs regardless of meat sources from different species.

The 6th industrialization, which is the policy strategy to combine the 1st, 2nd, 3rd agro-food industries in order to create synergy effects, is one of the most important policy strategies for the Korean government. Local governments as well as the central government, especially the Ministry of Agriculture, Food and Rural Affairs, have introduced various specific programs for the 6th industrialization. Among them, the 6th industry antenna shops located in Cheonan and Daejeon which were introduced by the Chungcheongnam-do Provincial Government to offer a better market place for 6th industry producers. However, few studies have been conducted to evaluate the performance of 6th industry antenna shops. The purpose of this paper is to analyze consumers' satisfaction of 6th industry antenna shops through survey and econometric modeling and to present some implications of the better operation of the 6th industry antenna shops. The results of the studies in this paper present some of the following findings: first, the overall level of satisfaction towards 6th industry antenna shops is high but consumers still claim some problems. Second, products which are sold at 6th industry antenna shops have important problems, including high prices and deficient product variety. Third, if these problems were fixed, the operation of 6th industry antenna shops would be successful and contribute to the development of 6th industrialization in Korea.

The purpose of this study is to analyze the influence of the working-environment and job-satisfaction on the turnover intention of infant-care teachers. For this study, a survey was conducted on 200 infant-care teachers, who work in facilities of Northern Gyeonggi-do. The main results of this study are as follows: First, the turnover intention of infant-care teachers has no statistically significant differences by socio-demographic factors. Second, turnover intentions relate negatively to working-environment and job-satisfaction. More job-autonomy reduces the turnover intention and more job-conflict and job-burden increases the turnover intention. Third, the working-environment and job-satisfaction have influences on the turnover intention of infant-care teachers in the regression model. In conclusion, we need to improve the working-environment and to enhance job-satisfaction in order to reduce the turnover rate of infant-care teachers.

The purpose of the study is to present the social welfare center planning factors of space for promoting intergenerational exchanges between the elderly and children. To achieve the purpose, the study conducted a survey of professionals on the importance of planning factors. The results are as follows. First, it is surveyed that less high are Korean social welfare center planning and availability extents of space for intergenerational exchanges, while less no profound are the necessity and concern of such spaces. The result suggests that social welfare centers need a concrete planning of space for intergenerational exchanges. Second, it is identified that in order to promote intergenerational exchanges, there need to plan planning factors of each space, especially with focus on 'outdoor space' and 'specific space.' Third, it is revealed that regarding the importance of factors of 'specific space,' physical supports account for the high rates; architectural factors providing free space contribute to the supports of physical development; and decorative factors giving visual effects could be helpful for behaviors. Fourth, it is unveiled that the supports of physical behaviors are of the most importance in 'connecting space'. This would be planned as a path that gives a free access in spaces, with attention being paid to safety. Lastly, it is shown that in the case of 'outdoor space,' the supports of physical development are of the most importance. Given the fact that 'outdoor space' offers a wider scope of activities, and accommodates various available elements in connection with surrounding environments, it is considered that the space would be of help for intergenerational interactions. The study is expected to be utilized as the preliminary data which proposes the social welfare center planning factors of space for promoting intergenerational exchanges between the elderly and children.

Vivianite (Fe₃²⁺(PO₄)2·8H₂O) and green rust ([Fe₄²⁺Fe₂³⁺(OH)^-₁₂][SO₄^2-·2H₂O]^2-), ferrous containing minerals, could remove aqueous U(VI) in 5 min. and the efficiencies of green rust were roughly 2 times higher than that of vivianite. The zeta potential measurement results implies that the better performance of green rust might be attributed to the favorable surface charge toward uranyl phosphate species. The removal behaviors of the minerals were well fitted by pseudo-second order kinetic model (R² > 0.990) indicating the dominant removal process was chemical adsorption. Effects of Ca²⁺ and CO₃^2- at pH 7 were examined in terms of removal kinetic and capacity. The kinetic constants of aqueous U(VI) were 8 and 13 times lower (0.492 × 10^-3 g/(mg·min); 0.305 × 10^-3 g/(mg·min)) compared to the value in the absence of the ions. The thermodynamic equilibrium calculation showed that the stable uranyl species (uranyl tri-carbonate) were newly formed at the condition. Surface investigation on the reacted mineral with uranyl phosphates species were carried out by XPS. Ferrous iron and U(VI) on the green rust surface were completely oxidized and reduced into Fe(III) and U(IV) after 7 d. It suggests that the ferrous minerals can retard U(VI) migration in phosphate-rich groundwater through the adsorption and subsequent reduction processes.

The ultimate goal of environment education plays an important role in forming knowledge, skill, attitude and a point of value along with sustainable development in the regions. Recently, however, environment education is comparatively despised due to college-entrance-exam-focused education policy. Ironically, environment education is more actively implemented at informal institutes rather than formal ones. Environment education at schools is based on the school curriculum, but at informal educational institutes enjoy much more freedom in choosing learners, places and programs. Among them, the place is one of the most important factors of environment education. Therefore, in order to maximize the goal of environment education in this study, a specified program was developed and applied to a certain place to investigate its features and effects. Also the program was checked if it reflexes the environment education goal by using environment education program analysis frame. The results are as follows; according to the analysis of the program, the program was most effective for the two goals of offering hands-on experience and presenting motivations. The second most effective result of the program lied in the goal of knowledge, functions, value and attitude. And the teachers who used this program concluded that, when the program was applied to unmanned islands, offered stronger motivation due to their natural surroundings. Furthermore, direct experience is recommended because it can give us better conditions to collect data and to enhance interpretation ability.

This experiment was conducted in order to examine what consists of romantic beliefs of college students, the overall tendency of the beliefs and motivation of marriage, the differences in the belief and motivation of marriage, and the influence of the beliefs toward it. A survey method was used and 394 students participated in this study. The major results of this study were as follows: First of all, there are four components in students' romantic beliefs, which are almighty love, destined love, hopes for romantic love, and only one & true love. Second of all, the students somewhat showed high level of romantic beliefs. This resulted due to the high level of romantic love but low level of only one & true love. Moreover, their motivations toward marriage which consists of intimacy and economic needs, were seen as the most important values in determining marriage. However, marriage due to social impact and the needs for personal growth were found to be placed in the lowest. Thirdly, male students in particular, showed higher beliefs in almighty love and destined love. The students of religion reported higher beliefs in destined love and only one & true love. Moreover, students who have a partner also showed higher beliefs in almighty love and only one & true love. On the other hand, for motivation of marriage, students showed higher inclination to choose for the desire for large families and children as their motivations, particularly for males. Students in the lower age group also showed higher inclination to choose for intimacy and economic needs as their motivations. Finally, according to the result of the hierarchical regression analysis, the higher the students' beliefs for destined love and the lower it is for hopes for romantic love, predicted higher possibility for the social impact and the needs for personal growth as their motivation of marriage. Moreover, the higher the belief for destined love and hopes for romantic love, the higher it is of their inclination to consider intimacy and economic needs for their motivation of marriage. Lastly, the higher it is for the students' belief toward almighty love, the higher it is for one to marry with a consideration and desire for large families with children.
