In sweet cherry (Prunus avium L.) growing there are several severe problem which have to be overcome to produce highly graded fruits because of fruit rots and fruit crackings, if there is frequent precipitation during immature fruit step and picking season. In order to reduce fungicide sprayings and produce qualified fruits in areas with rainy season like as South Korea, rain-sheltered growing is necessary absolutely. Sweet cherry blooms early to medium April in southern area of South Korea. If we depend on honeybees (Apis mellifera) distributed in natural ecosystem, it is not easy to get normal fruit-set every season because of low temperature around blooming time. And also bee keepers seldom sell honeybee hives as a pollinator during spring, instead they keep honeybee hives to get honey. Recently use of B. terrestris as a pollinator of cherry tomato, oriental pumpkin etc. grown in protected cultivation system increase abundantly. Therefore, in this study we studied B. terrestris as an alternate of honeybee to pollinate sweet cherry grown in rain shelter. In part of foraging activity B. terrestris shows staying on a cherry flower for about six second and visiting frequency of 11 flowers per minute. However A. mellifera stayed about 15 second on a flower and visited 4~5 flowers per minute. There were no significant difference in fruit-setting rate and fruit characteristics after using B. terrestris and A. mellifera as pollinators of sweet cherry. Consequently there is no negative effect when we use B. terrestris as an alternate pollinator of A. mellifera in sweet cherry cultivation under rain shelter.

In this study, the special guard duties and duties within the Organization of communication influence on immersed in the interpersonal skills to discover the effects of the parameters of the educational facilities in the airport traffic facilities, and anything that increases the special guards, September 20-target 2015 2015 October 20 poll. The study compared the results of analysis are as follows. Analyze the effect of model parameter, interpersonal skills are also satisfied with the saturated model, duties (duty immersion) interpersonal skills for the parameters of the effect analysis when you look at the results, the higher the level of communication and interpersonal relationships and job satisfaction, but also high level of (job immersive) interpersonal communication in interpersonal relationships, higher levels are high. SMC, job satisfaction, job commitment 23.9% 7.2%, 19.3% of interpersonal relationships. In addition, the duties of immersive interpersonal skills for the parameters of the effect the results of the analysis of communication and its impact on job satisfaction (duty of immersion) in interpersonal work parameters can verify that it exists. Communication on direct interpersonal relationships, keep in mind that the statistical effect also appeared. If you look at the overall results of this study, special communication organization of job satisfaction and security guard job influence on interpersonal skills immersed the parameters of the effect.

In this study, the factors of the industrial complexes were analyzed in a comprehensive review, and the research model was developed and related variables were adopted to the purpose of this study. Also, the determinants of location are analyzed by three factors of infrastructure stabilization, industrial resource access, and residential neighborhood factors. For the analysis of this study, the hypothesis was analyzed through the path analysis of the SEM through the set hypotheses based on the research model. As a result of analysis, it is analyzed that TI factors and RA factors of infrastructure, IF group, are both influenced by industrial location. In addition, there is a statistically significant correlation in the analysis between the parameters of the NEF and the determinants of industrial location. The results of this study are expected to provide useful guidelines for industrial infrastructure development and industrial complex development projects at national and local government.

The purpose of this study is to increase the long term care service quality. This study examines how leadership style and organizational commitment can effect service quality. The basic data has been made by 318 long-term care workers. Major findings are reported: transformational leadership effects affective commitment, normative commitment, continuance commitment and service quality. And transactional leadership effects continuance commitment, too. Espicially, the mediating effects of normative commitment in the relationship between transformational leadership and service quality were verified. These results have implications for the applications of transformational and transactional leadership and on human resource management and suggest on the support policy.

This study investigates the effects of authentic leadership and organizational supports on the organizational citizens behavior of public welfare facility employee. Structural equation model with four latent variables were constructed to test the hypothetical relationships between variables. Out of 230 people from welfare facilities in Yong-in City were sampled and 216 were answered the questionnaire. Results suggests that authentic leadership and organizational support perceptions were shown to have a positive(+) significant effects on the job engagement and organizational citizenship behavior. Authentic leadership and perceived organizational support are effected as a direct positive effect on job engagement, and the influence of perceived organizational support was recognized as greater fact than the authentic leadership. Variable 'job engagement' took a intermediating role between two independent variables and organizational citizenship behavior. Based on the hypothesis test results we might conclude that welfare facility employee whose task require emotional engagement need to be supported by systematic plan of material resources.

The purpose s of this study is to verify the status of barrier-free certification in an elementary school. To achieve this, the architectural characteristics of an elementary school and proposed opinions about the process of barrier-free certification were analyzed. The results of this study are as follows: (1) barrier-free certification in an elementary school is valid for inclusive education and accessibility for students with disabilities. (2) Regarding the school district and safe accessibility for the school, it is necessary to minimize the differences in land levels around the school. (3) Considering the opinions on intermediate facilities from the road to the main entrance, it is necessary to set the finish level of the first floor and to minimize the establishment of ramp or steps to prevent the backflow of rainfall.

To promote the carbon emission trading scheme and reduce greenhouse gas (GHG) emission as following 'Korean GHG & Energy Target Management System', GHG emissions should be accurately determined in each industrial sector. For the estimation method of GHG emission from waste landfill, there are several error parameters, therefore we reviewed the estimation method and proposed a revised method. Methane generation from landfill must be calculated by the selected method based on methane recovery rate, 0.75. However, this methodology is not considered about uncertainty factor. So it is desirable that $CH_4$ generation is estimated using first order decay model and methane recovery should use field monitoring data. If not, $CH_4$ recovery could be applied from other study results; 0.60 of operational landfill with gas vent and flaring system, 0.65 of operational site with landfill gas recovery system, 0.90 of closed landfill with final cover. Other parameters such as degradable organic carbon (DOC) and fraction of DOC decompose ($DOC_f$) need to derive the default value from studies to reflect a Korean waste status. Proper application of MCF that is selected by operation and management of landfill requires more precise criteria.
