The purpose of this study is to examine whether the enhancement of convergent job competence of social worker working in a social welfare facility affects the quality of life. In order to achieve the purpose of the study, we surveyed 20 social welfare workers working in 20 social welfare facilities in Gyeonggi area and used 188 pieces collected. The random sampling method was used for the sampling method. As a result, there was a positive correlation between personal competence and satisfaction, environmental competence and dissatisfaction, relationship competence and satisfaction in social workers' competence enhancement and quality of life. And social competence's individual competence and environmental competence play a positive role in dissatisfaction. Also, it can be seen that the relationship competency plays a negative role in dissatisfaction. The degree of individual competence, the ability to control the mind to turnover, and the relationship capacity play a positive role in satisfaction. Therefore, in order to improve the quality of life of the social welfare workers, it is expected that there will be a positive effect in implementing the job capacity enhancement education program for the social welfare workers.

This study was conducted in 241 fire officers at fire stations in Daejeon Metropolitan City to determine their oral health care behavior status and obtained the following results: First, men were more likely to brush their teeth 3 times a day and women were more likely to brush their teeth 4 times a day; those who were in their twenties and had ${\leq}5$ years of career brushed their teeth for ${\geq}3$ minutes. Second, the respondents who were in their twenties and thirties and had <10 years of career were more likely to use auxiliary oral hygiene devices and fire captains and those at higher positions were more likely to have received oral health education. Third, the respondents having received oral health education were more likely to use auxiliary oral hygiene devices and to have their teeth scaling within a year. While the fire officers were fortunately at good levels of oral health care, taking the poor working environment into account, the efforts to develop job-customized oral health programs in which IT and robot technologies are combined to improve oral health and take measures to publicize the programs and to give better treatment to fire officers are expected to put them in better oral health care status.

This study examined the effect of the nervous-system-stimulating caffeine on the nerve conduction velocity. The purpose of this study is to investigate the effect of caffeine that stimulates the nervous system on nerve conduction test. Although both measurement intervals did not show statistically significant differences when comparing the pre- and post-NCV values within the control and individual experimental groups, it was found that the nerve conductivity in the Axilla-Above Elbow section increased significantly after caffeine intake for the experimental group. Caffeine intake, which has increased the nerve conduction velocity (NCV), was determined to play roles in improving motor skills, muscle strength and nerve performance by temporarily increasing the nerve conduction velocity. Through this study, we learned that caffeine has an influence on the peripheral nervous system as it helps to improve the nerve conduction velocity. upon an appropriate amount of caffeine intake. We hope that these results will help develop treatment and diagnostic methods for patients with nerve dysfunction and myofunctional disorders.

The domestic construction market started to expand steadily since 1970s. The building market which utilizes a sandwich panel with advantages of economical construction expenses and convenient construction has grown rapidly in recent years. However, the companies which specialize in constructing sandwich panels are relatively small or medium size, compared with other construction companies. As a result, studies on the improvement of productivity have not been conducted sufficiently. In this study, the construction sites of sandwich panel are investigated, and the work processes by each team are analyzed. Additionally, the productivity and the construction cost of each work group are analyzed by constructing a model using the Web-Cyclone. It analyzed sensitivities about change of productivity and work costs following in processing place of the panel which is one of the productivity effect factors, so it assayed the optimized productivity by each work group and work costs. Analysis showed that 30% of productivity has improved compared with the factory processing work group, and analysis of work costs showed that about 15% of work costs was increased. Also sensitivity analysis of opening ratio showed that the work costs optimization will be accomplished when about 20% of opening was processed from the factory.

This study proposes effective overseas market entry strategies that could allow Korean logistics companies to develop international capabilities and become global firms by adapting to environmental changes in global logistics. First, it reviews the overseas networks of Korean international freight forwarders and the recent trends in the global logistics market. Then, it surveys the conditions of two groups of freight forwarders, namely partnerships and subsidiaries, which are categorized according to type of entry into foreign markets. These companies' networks are concentrated in East and Southeast Asia regardless of network type. As a result, the ability for partnerships to network is higher than that of subsidiaries. However, subsidiaries are small in number and located in various regions because of their initial stage, which is why their businesses depend on the price competitiveness of the parent company. The satisfaction and performance of subsidiaries are both generally low according to the presented findings. In addition, the successful strategies of international freight forwarders include following operations, specializing their logistics services, building collaborations among small and medium-sized companies, recruiting and training professional human resources in international logistics, and entering markets together with their customers. Overall, this study highlights the importance of measuring and evaluating objectively the level and performance of overseas networking through a survey about the internationalization of Korean freight forwarder companies. To conclude, this study is considered to contribute to raising their global competitiveness by suggesting strategies derived from the survey findings and SWOT analysis.

Economic analysis predicts that the drone market will grow, and the growth of the toy and hobby drone market is expected to gradually expand. Drone expectations are rising due to the net economic function of drone market growth, but accidents due to improper management and operations are also increasing. The difference in toy drone performance is incomparably small compared to industrial drone performance, but the ordinary buyer can not know whether the difference can cause an accident during use. The toy drones used in this study were obtained from KC and CE certification, and 20 kinds of drones were used. The flight time ranged from a minimum of 3 minutes to a maximum of 12 minutes, and the control distance ranged from a minimum of 20m to a maximum of 380m. Therefore, it is necessary to secure product safety through sampling inspection of the radio wave output of toy drones, and it is also necessary to mount an algorithm that automatically lowers the altitude or hover when exceeding the limit flight distance. For future research, we will build data to establish toy drone safety standards through a altitude testing and impact testing of toy drone.

This study was attempted to investigate the mediating effect of the tolerance of dating violence in the influence of female college students' perception of dating violence on their sexual self-assertion. The subjects of this study were 161 female students enrolled in universities in the Chungbuk region. As research instrument, Jeong(2013)'s perception of dating violence, Jeong(2016)'s sexual self-assertiveness, and Nam(2003)'s dating violence acceptability were used. For data analysis, frequency, percentage, correlation analysis, hierarchical regression analysis, and Sobel test were performed using SPSS WIN 21.0 program. As a result of the study, first, there was a significant positive correlation between perception of dating violence and violence tolerance(r=.43, p<.001), and a significant negative correlation between violence tolerance and sexual assertiveness(r=-.20, p<.05). Second, the perception of dating violence had a significant positive effect on sexual assertiveness(𝛽=.43, p<.001), and the explanatory power was 19%(F=36.10, p<.001). Third, it was found that the decrease in the effect of female college students' perception of dating violence on sexual assertiveness was significant(Z=2.05, p<.05), violence acceptability showed a mediating effect on the effect of dating violence perception on sexual assertiveness. Based on this study, it is suggested to develop a dating violence prevention program that can lower female college students' acceptability for violence, raise perception of violence, and strengthen sexual assertiveness.
