This study was attempted to provide basic data for developing future clinical competency enhancement of long-term care hospital nurses. Data were collected from 166 long-term care hospital nurses in G-do. Analysis was done using t-test, ANOVA, Pearson correlation coefficient, and Multiple regression with IBM SPSS WIN/21.0. The subjects' clinical competency was positively correlated to death awareness (r=.28, p<.001). The most influential factor on the subjects' clinical competency was death awereness (β=.235, p=.002), followed by marital status 'married' (β=-.214, p=.004), and have choice in days off 'agree' (β=.235, p=.002). The explanatory power was 16.2% (F=10.528, p<.001). Therefore, educational programs raising awareness of death, consideration of fellow nurses to have days off when desired, and encouraging married nurses to work are needed to enhance the clinical competency of long-term care hospital nurses. Utilizing the results of this study as basic data for clinical competency enhancement and in working schedule adjustment of long-term care hospital nurses is expected.

The purpose of this study is to develop and secure the human resources of SMEs by examining the causal relationship between job characteart-time job experience and career development of youth. In order to achieve the purpose of the study, 10,119 youths in the middle and high schools in Korea who participated in the panel data collection by the Korea Youth Policy Institute were surveyed from May 20 to July 12 in 2013, Panel data were used. The results of the study are as follows. First, it was found that the part-time job experience had a statistically significant effect on the planning, which is a sub-area of career development. Second, the part-time job experience has a statistically significant effect on attitude, a sub-domain of career development. Third, it was found that the part-time job experience had a statistically significant effect on the self knowledge, which is a sub-domain of career development. Fourth, it was shown that the part-time job experience had a statistically significant effect on career behavior, one of the sub-areas of career development. Fifth, it was found that the part-time experience characteristics had a statistically significant effect on the independence of sub-domains of career development. Therefore, since the part-time work of youth has a positive effect on career development, it is expected that the human resources of the future of SMEs will be secured if they create a place for career experience and job experience in connection with middle, high school and SMEs.

The objective of this study was to investigate the antioxidative components and anti-oralmicrobial effect of bamboo (Phyllostachys nigra var. henonis Stapf) leaves. The moisture, crude protein, crude fat, crude ash, and carbohydrate contents were 6.30%, 5.10%, 1.73%, 10.61%, and 76.26%, respectively. Vitamin C content was higher than Vitamin A and E contents. Among organic acids, citric acid content was the most abundant organic acid, followed by succinic acid, acetic acid, malic acid, and formic acid. Total polyphenol and flavonoid contents were 21.66 mg/g and 42.78 mg/g, respectively. Minimum inhibitory concentrations (MICs) of extracts of bamboo leaves for Streptococcus mutans and Streptococcus sobrinus were determined to be 0.04% and 0.16%, respectively. MICs of extracts of bamboo leaves for Porphyromonas gingivalis and Prevotella intermedia were determined to be 0.02%. Extract of bamboo leaves had strong antimicrobial activity against S. mutans, S. sobrinus, P. gingivalis, and P. intermedia at a concentration of 0.32%. At this concentration, extract of bamboo leaves inhibited growth of these pathogenic bacteria up to 60 h. The results of the present study demonstrate the antimicrobial effects of bamboo leaves ethanol extract against oral pathogenic bacteria, suggesting that bamboo leaves could be an effective natural agent for oral hygiene.

It has been widely researched in many studies what is the most effective way to learn English as a second language. It has been generally accepted that the most effective teaching method is to make students interested in learning of English. Teaching method has to be modified with the change of the times according to the demand of the students. The purpose of this study is to reveal that language teaming method through internet could be more effective than that of the existing teaching one by offline loaming. For this purpose some subject students were divided by two groups of the experimental and of the controlled. From the result of the study it could be derived that teaching method, by means of cyber lecture, make a great effect not only on the attitude but on the achievement of the students when they are in the class of English as a second language. This paper also shows what could be the typical model for the teaching method by internet based on the experiment. This kind of way of teaching is supported by the questionnaire which has much more positive response from the students who were in the member of experimental group. Finally such a experiment would be described based on the Web-oriented teaching method with the respect of education of digital contents.

The effect of plum wine on lipid metabolism and lipid peroxidation in rats with chronic ethanol consumption was evaluated. Sprague-Dawley rats were randomly divided into the following 4 groups; water (NC), alcohol control (AC), low concentration plum wine (LP) and plum wine (P). The alcohol content of experimental drinking water of AC, LP and P were 6%, 6% and 12%, respectively. Animals were fed AIN-76 diet and experimental drinking water for 4 weeks. LP group showed significantly decreased liver weight per 100 g body weight, the levels of total cholesterol and atherogenic index in plasma whereas the ratio of HDL-cholesterol to total cholesterol was significantly increased in comparison to that of AC group. LP and P groups showed significantly decreased total lipid, total cholesterol in liver tissue, AST and ALT activities of plasma as compared with that of AC group. LP and P groups showed a significant decrease in the level of plasma lipid peroxidation products and LP group showed a significant decrease in the level of liver lipid peroxidation products as compared with that of AC group. These results suggest that supplementation of low concentration plum wine may exert more beneficial effects than pure alcohol beverage on lipid metabolism and lipid peroxidation products in chronically alcohol-treated animals by improving lipid profiles in plasma and liver tissues and decreasing plasma and hepatic lipid peroxidation product.

The aim of this study was to investigate the effect of a mixture of ethanol extracts of Black oryzasativa, Sesamum indicum, Oryza sativa, Rhynchosia Nulubilis, and Polygoni multiflori radix (MIXEE) on melanogenesis to develop a natural product for black hair growth. An accumulation of hydrogen peroxide ($H_2O_2$) in hair follicles, which reduces melanin synthesis, is responsible for hair graying. In the present study, MIXEE showed scavenging activity against DPPH radicals and reducing power. In addition, it reduced the cellular $H_2O_2$ level, indicating that it could inhibit oxidation and promote melanin synthesis, which was decreased by $H_2O_2$. On the other hand, it did not affect tyrosinase activity in vitro but promoted the turnover of L-DOPA into melanin. MIXEE promoted melanin synthesis at the cellular level in B16F1 cells. Furthermore, MIXEE increased the expression levels of superoxide dismutase 2 (SOD2) and SOD3 in western blot analysis. In addition, MIXEE increased the expression levels of tyrosinase-related protein (TRP)-2, which promoted melanin synthesis from L-DOPA. The results suggested that MIXEE could promote melanogenesis. Therefore, MIXEE may have potential as a natural product for promotion of melanin production and reversal of gray hair to black hair.

This study examined characteristics and usefulness of middle-aged and older people's vocational training participation. Among sub-age groups categorized by the position in career cycle and the employability, 61~68 year old group(after retirement age group) had the biggest difficulties on the training including computer-based training and showed the lowest employment result compared to other sub age groups; major career(30~45), career transition preparation(46~52), career transition(53~60). However, the career transition age group utilized vocational training in the aspect of career search and the after-retirement age group in the aspect of preparation for older age and hobby. On the other hand, factors such as career adaptability and perceived education difficulties affected on the training usefulness in the aspects of career search and preparation for older age and hobby while perceived career barriers, career relevancy and relationship ability affected on the employment result. Based on these findings, this study suggests that vocational training provide more suited course for the boundaryless career seekers and include relationship enforcement and positive attitude development to overcome perceived career barriers for middle-aged and older people.

Our current society is experiencing a mass upheaval through globalization: mobility, hybridity, and cultural diversity are part of this world phenomenon. We can say that these changes are a result of people crossing borders due to international travel, immigration, emigration, studying abroad, labor, international marriages, fast and comfortable transportation, and the Internet. According to 2018 UNPD(Untied Nations Population Division)'s data, the international migrants have exceeded 258 million as of 2017. The increased number of migrants signifies that people with various backgrounds move from their own culture to a drastically different one. Interacting with different cultures can give people the chance to experience abundant lifestyles and improve life qualities. During that process, however, the differences between cultures can cause not only misunderstandings, conflicts, and violent collisions, but also xenophobia or radical nationalism. The current society is confronted with a problem: the people cannot stubbornly cling to a homogenous ethnicity anymore, which makes the coexistence between the citizens and immigrants necessary. Through these circumstances, I aim to suggest an educational model and a practical curriculum from a Christian perspective as the aim of this study. It seeks to encourage Christians to flexibly respond to these conflicts and collisions, and to fulfill their social responsibilities faithfully. For this reason, I will explore and seek sharing practical values through both shalom's communality as a theological approach and postconventionality in mature adults as a social-scientific approach. Consequently, I have few requests for the readers. First, approach with openness, understanding, and respect for other culture. Second, see this study as one step of confronting the global problem for coexistence and coprosperity of all social agents in the earth, a limited space. Third, notice that this study uses the interdisciplinary approach (theological and social scientific view) for a shareable, practical value that consistently leads the curriculum of my thesis, and a scientific method to eliminate bias. Lastly, understand that this study will eventually be used in educational practice, and as a result it prioritizes giving thought to the Christian educational environment. This study begins by exploring the conflicts and collisions between diverse cultures of our current society in international and national cases. Afterwards, I will reflect on how we can manage these conflicts and collisions by exploring the social-scientific view, postconventionality in mature adults, the theological view, and shalom's communality as a complement for the postconventionality's personal dimension. In conclusion, I suggest a curriculum that achieves peace as a practical value based on postventionality and shalom's communality for this study's goal.
