This study was conducted to identify the effects of interpersonal communication between health care providers after receiving supplementary education. The participants of this study were 433 health care providers who work at 29 general hospitals in Gwangju Metropolitan City and Jeollanamdo Province. Data were collected from June 8 to June 25, 2018 and evaluated by t-tests, dispersion analysis, correlation analysis and stepwise regression. The results were produced by investigating interpersonal communications according to socio-demographic and health-related characteristics including age, education level, bed size of the hospital at which the participant worked, job satisfaction, hospital location, personal health status, experience with health care management and experience with depression. There were significant differences in communication observed according to supplemental education awareness regarding age, bed size of hospital, occupation, wage, type of medical institution of employment, job satisfaction, work location, health status, health care education experience and chronic disease. There were positive correlations between supplemental education awareness in health workers and their interpersonal communication. The factors that had positive effects on interpersonal communication were level of education and health-related education experience, while age, hospital bed size and job dissatisfaction had negative effects. Finally, support environment, learning transfer and results were identified as sub-factors of supplemental education. Based on the results above, it was proposed that educational training to enhance results, provide a supportive environment and foster learning transfer be developed to increase communication between health workers and provide a safe health service for patients.

This study was conducted 1) to investigate the effects of treatment and other factors on the quality of life of thyroid cancer surgical patients and 2) to provide fundamental data for development of an intervention and symptom management program to improve the quality of life of those patients. A total of 76 patients who were diagnosed with thyroid cancer and underwent thyroidectomy from July 2013 to December 2014 participated in this study. To investigate the factors affecting quality of life, a t-test and ANOVA analyses were conducted, after which multiple regression analysis was performed. The results were statistically significant between preoperative and one month after surgery of sex, cancer history, fatigue, and quality of life until 3 months after surgery of stage, cancer history, anxiety, and pain. Multiple regression analysis showed that the most influential factors affecting the quality of life were depression and fatigue at one month prior to and after surgery and anxiety at three months after surgery, while no factors were found to be influential at six months after surgery. Overall, the results of this study suggested that it is imperative to manage depression and fatigue one month prior to and after surgery to reduce the physical and psychological pain experienced by thyroid cancer patients. Moreover, three months after the surgery, anxiety should be closely monitored and controlled to improve the quality of life of the patients. This approach is expected to reduce the burden on the health care system and social costs, which will positively affect public health.

Asan Oeam village is a town that has been formed since about 500 years ago. It is a folk village centered on Yean Lee and designated as National Folk Cultural Property No. 236. However, the original shape of the thatch, which has regional characteristics, is disappearing. Therefore, I want to study the architectural characteristics of the house which is well preserved in the original shape. The Genjaegotaek is located in the center of the Oeam village. The composition of the house consists of a Munganchae, Salangchae, Anchae, Sadang. The Anchae is an 'ㄱ' shaped house, and it is shaped like a 'ㅁ' which is opened by facing. The wide yard in front of the Salangchae is made of strangely shaped rocks, a hundred-year-old pine, old pagodas, ponds, pavilion. Outside the main gate, there is an 'ㅡ' shape thatch on the west. The Galabjib of Geonjaegotaek is a servant house, and the shape is a ㄱ type. The plane remained well in its original shape, thatch is consisting of a kitchen-room-daecheong maru-room. A Galabjib of Geonjaegotaek can not represent all the thatch of a Oeam village. However, it is expected that this study will be used as a basic data when the study by the thatch in this area is conducted through the analysis of the type.

Securing reference information (inventory) is essential for proper conservation and management of protected areas. Moreover, the investigation results should be available for comparison and evaluation. For this study, we established seven investigational lattices and carried out the field examinations to obtain comparable data in the Donggang river basin ecological and scenery conservation area, We conducted a total of 16 field surveys and identified a total of 830 taxa that is composed of 127 families, 408 genera, 716 species, 10 subspecies, 88 varieties, and 16 forms. We identified a total of 487 taxa in the 6th investigational lattice and 457 taxa in the 4th. We observed 6 species (grade II) designated by the Ministry of Environment as the endangered plants, one "species to monitor" designated by the Ministry of Environment, and 23 taxa designated as endemic species. Regarding the floristic characteristics plants, 15 taxa of grade V, 27 taxa of grade IV, 38 taxa of grade III, 31 taxa of grade II, and 19 taxa of grade I were identified. The 6th investigational lattice showed the largest number of taxa at 70. A total of 58 taxa were identified as the naturalized plant, and the 6th investigational lattice showed the most at 35 taxa. The Donggang river basin ecological and scenery conservation area was assessed to be an extremely important area to conserve and maintain plants species diversity not only in the regional scale but also national scale.

The purpose of this research was to introduce a network analysis method for analyzing technology trends in the aerospace industry at the Farnborough International Airshow (FIA), one of the world's three major airshows. Civil and defense companies and government and military officials from 112 countries and 1,500 agencies convened at FIA 2018 to share and explore recent trends in the aerospace industry. We studied aerospace technologies from 45 countries, 1,108 exhibiters, and 223 technology categories via centrality analysis. The results from the network analysis showed that machining is the center of aerospace technology. However, there were quite different tendencies, depending on the region and country. The centers of aerospace technology are machining in Europe and the United Kingdom, aircraft components in Asia, and engine components/controls in the United States. In Korea, no one key technology was recognized, due to the country's small attendance. We hope this research will be conducive to aerospace technology-and-research planning, and that it will be an appropriate tool to help domestic manufacturers boost their exports.

Increasing crop production with the same amount of resources is essential for enhancing the economy in agriculture. The first prerequisite is to understand relationships between the resources. The concept of WEF (Water-Energy-Food) nexus analysis was first introduced in 2011, which helps to interpret inter-linkages among the resources and stakeholders. The objective of this study was to analyze energy-water nexus in greenhouse cultivation by estimating reference evapotranspiration and heating load. For the estimation, this study used the physical model to simulate the inside temperature of the agricultural greenhouse using heating, solar radiation, ventilated and transferred heat losses as input variables. For estimating reference evapotranspiration and heating load, Penman-Monteith equation and seasonal heating load equation with HDH (Heating Degree-Hour) was applied. For calibration and validation of simulated inside temperature, used were hourly data observed from 2011 to 2012 in multi-span greenhouse. Results of the simulation were evaluated using $R^2$, MAE and RMSE, which showed 0.75, 2.22, 3.08 for calibration and 0.71, 2.39, 3.35 for validation respectively. When minimum setting temperature was $12^{\circ}C$ from 2013 to 2017, mean values of evapotranspiration and heating load were 687 mm/year and 2,147 GJ/year. For $18^{\circ}C$, Mean values of evapotranspiration and heating load were 707 mm/year and 5,616 GJ/year. From the estimation, the relationship between water and heat energy was estimated as 1.0~2.6 GJ/ton. Though additional calibrations with different types of greenhouses are necessary, the results of this study imply that they are applicable when evaluating resource relationship in the greenhouse cultivation complex.

This study has empirically analyzed how far corporate governance and CSR(Corporate Social Responsibility) fit are related based on prior research indicating that corporate governance is one of the primary factors. Previous research suggested that there may be different types of CSR fit, but there have been only limited number of empirical studies. This study filled this gap by categorizing CSR fit into three types (functional fit, target fit, and size fit) and investigating whether different types have different effects. We used data from the Corporate Social Responsibility White Paper for the 2009-2012 period, as well as the Korea Corporate Governance Service (KCGS) index. As a result, we found that there is a negative (-) relationship between corporate governance and CSR fit(${\beta}=-.023$, p<.05). This can be interpreted that companies with weak corporate governance are attempting to increase the trust level of stakeholders and to reduce the uncertainty of CSR through high-CSR-fitted programs. The test results showed that functional fit and target fit both had negative (-) relationships with corporate governance (${\beta}=-.021$, p<.05; ${\beta}=-.016$, p<.1), while size fit did not have a significant correlation with corporate governance (${\beta}=-.005$, p=.511). The results of this study supported the previous studies' suggestions that CSR fit has different effects on each type, indicating a need for further reflection on the relationship between corporate governance and CSR fit. Also, the results of this study showed that corporations should take a strategic approach to operating CSR fit.

The study empirically investigates financial factors that may influence on corporate R&D intensity during the post-era of the global financial turmoil (from 2010 to 2015) to mitigate possible spillover effect associated with the crisis. Concerning the empirical research settings of the study, chaebol firms listed in the KOSPI stock market are used as sample data with adopting various econometric estimation methods to enhance validity of the results. In the first hypothesis test, it is found that there exist inter-industry financial differences in terms of the ratio of R&D expenditure across all the sample years, but the statistical differences may arise from only a few domestic industries beloning to the high-growth sector. Moreover, it is also interesting to identify that, for the high-tech sector, 3 explanatory variables such as R&D intensity in a prior year, firm size and change in cash holdings are proved to be financial factors to discriminate between chaebol firms and their counterparts of non-chaebol firms, whereas a proportion of tangible assets over total assets as well as the former two variables are shown to be significant factors on the R&D intensity for the low-tech sector.

This study has researched and analyzed the relation among adolescents metabolic syndrome, dietary life, physical activity and mental health using $7^{th}$ National Nutrition Survey of $1^{st}$ year(2016) to provide the base data for the prevention of adolescent metabolic syndrome and the promotion of mental health. The subjects have been aimed at 13-18 year-old adolescents. The normal group consists of 201 males(56.4%) and 187 females(47.4%) and the adolescents with metabolic syndrome are composed of 9 males(56.4%) and 6 females(43.6%), totally 403 subjects. As a result of analyzing on the relation among adolescents' metabolic syndrome, dietary life, physical activity and mental health, the main influencing factors of metabolic syndrome are as follows. First, with regard to physical features, as BMI increases 1, the prevalence rate of metabolic syndrome multiplies 1.746 times. Second, when eating breakfast once to twice a week, the prevalence rate of metabolic syndrome decreases 0.87 times. Third, with regard to physical activity, as usual sitting hours a day increase 1 hour, the prevalence rate of metabolic syndrome multiplies 1.054 times. Fourth, the relation between metabolic syndrome and mental health of adolescents is not significant at all. Thus, the further study on metabolic syndrome focused on adolescents should be extended through the development of various variables of dietary life, physical activity and mental health focused on adolescents. In addition, the development of effective intervention program combining with dietary life, physical activity and mental health factors is necessary.
