The Altai Humanities Belt connecting Siberia to Central Asia is very important to the history of civilization. It had a huge influence on the formation of an ancient civilization in the Korean Peninsula. Therefore, a variety of studies have been carried out in the field of folklore and anthropology as well as archeology. One of these studies is about the oral epic. The oral epic remains in the form of a unique transmission in Korea, but it wasn't that long ago when it was noted as the component of the Altai Humanities Belt. In that context, some epics from Central Asia, Mongolia, and Siberia were introduced to Korea. This preliminary investigation is conducted to introduce the oral epic Olonkho from Yakutia in Siberia to Korean academia. Although it was revealed recently, Olonkho is highly valued. The epic study has been buried from the Western point of view, but Olonkho is expected to provide a global perspective to the field of epic study. Above all, it contains a very significant clue to a new study because the content and the style of performance are considerably different from those of the West. Additionally, the original form is relatively well preserved. In particular, it explains how human thinking and behaviors have changed in the transition from the mythical age to the heroic age. This change appears in the ethnic history of Yakutia, as well as in the formation process for all Altai countries around the 10th century. Therefore, this preliminary investigation will be a foundation to facilitate the translation of the voluminous Olonkho into Korean, and to conduct full-fledged research on it. In particular, it can motivate a study on the differences and similarities in comparison to the tradition of oral epics between Central Asia and the Korean Peninsula. Furthermore, it will serve as a foundation for the formation of the Altai Humanities Belt.

With progress of the sound and moving picture recording technology, sound and moving picture have been a tool for evidence and memory on human activities. Accordingly, in archival science the importance of oral history as a record is disseminating and the production of oral record is carried out actively. But for producing oral record in archival institutions, the identity of oral record need to be established more firmly. Archival science is the task which delivers the current appearance of life to future through records. Therefore producing oral record in archival science must have unique characters. And archival science is the task which is building current memory. Therefore the identity of oral more firmly. This article intends to explore the meaning and role of oral record from a perspective of archival science. All these days, the theories and methodologies had been developed focusing on written records mainly in the deep-rooted influence of positivism. But as it is enabled the creation and preservation of records through 'speech', it need to be noted that oral record is the very core of tool for delivering the current society shape and collective memory. Therefore this article will intend to explore the meaning and role of oral record as a part of effort to establish the identity of oral record.

Focusing on the potential impact of information and communication technology (ICT) on older adults' quality of life, this study empirically examined the influence of smartphone use in old age on life satisfaction, depression, social activity and social support of Korean older adults. In order to examine the effects of smartphone use, this study analyzed data from 630 questionnaire surveys from older adults aged 65 and over living in Seoul. The effects of smartphone use were tested using hierarchical multiple regression analysis, controlling for socio-demographic variables such as age, sex, spouse, education and income. Results showed that the effects of smartphone use on life satisfaction, depression and social activity of older adults were statistically significant. However, the effects of smartphone use on social support of older adults was not statistically significant. This study suggests that ICT such as smartphones in old age plays generally positive roles in enhancing psychological, mental and social aspects of quality of life. This implies that further practical efforts to expand the distribution and use of ICT in old age are required to improve quality of life and successful aging of older adults.

Chinese xian-xia films is a new genre that occurred through the fusion of the genre of martial arts and fantasy. This study analyzed the development of xian-xia films and the space aesthetics of xian-xia films through the miseenscene of the journey to the west films. In particular, the space for xian-xia in the films is divided into the human, urinary, heaven world and the space of conflict. It looks like the fantastic Middle Earth that Tolkien presented, however it is discriminatory in that it shows a highly Chinese appearance and overlapping world centered on the natural environment (the world of Mountains and Livers), such as mountains, deserts, caves, and grasslands, which usually appears in traditional martial arts history. Resently, the boom of journey to the west films is regarded as the change of the Chinese film industry under the influence of the development of IP (Intellectual Property) industry and the western fantasy genre in the 21st century China. This change marks the birth of the new Chinese fantasy "xian-xia" genre with the spirit of the present era that transcends the original world of journey to the west through the hybridization of the genre.

This quasi-experimental study was conducted to develop and implement a team facilitation program as well as to evaluate the effects of the program on Problem Based Learning (PBL) and how these influence on team dynamics. Data were collected in a convenient sample of 126 nursing students (intervention group=69; control group=57). Data were analyzed using ${\chi}^2$ test, T-test, and ANCOVA. SPSS23 was used. The intervention group received the PBL team facilitation program, whereas the control group received a human interaction training. The intervention group than the control group demonstrated significantly higher scores in a team dynamic among team members(F=10.35,p<0.01), trust among team members(F=9.86,p<0.01), communication(F=5.69,p<0.05), learning behavior of a team(F=4.57,p<0.05), and individual capability evaluation(F=5.12,p<0.05). Team performance was not significantly different between groups. This study reveals that the team facilitation program is an effective strategy to maximize the effects of PBL. We propose the need for educational strategy to support team function.

Peniphora sp. JS17, isolated from forest old tree, produced extracellular enzymes that decolorized human hair melanin. The JS17 strain had laccase and manganese peroxidase activity while it did not has lignin peroxidase activity. Batch culture indicated that the melanin decolorization activity of JS17 strain originated from laccase. The culture conditions to maximize the production of melanin bleaching enzymes from Peniophora sp. JS17 mycelia were investigated. Among the tested media for the laccase production, minimal medium (2% glucose, 0.2% malt extract, 0.1% $KH_2PO_4$, 0.4% $MgSO_4{\cdot}7H_2O$) showed the highest activity of laccase. Then, to optimize the culture condition for the laccase activity, the influence of various carbon and nitrogen sources was investigated in minimal medium. Among various carbon and nitrogen sources, 2% xylose and 0.4% tryptone showed the highest production of laccase, respectively. The enzyme was purified using $(NH_4)_2SO_4$ precipitation and Hitrap Q sepharose column, and the purified enzyme showed two isoenzymatic bands with molecular masses of about 70 kDa by SDS-PAGE. The melanin decolorization activity was 77% and 55% within 48 h in the presence of 1-hydroxybenzotriazole (HBT) and syringaldehyde, respectively, whereas only about 9% melanin decolorized in case of no mediator.

The aim of this study was to examine self-efficacy and work ethic on the moderating effect of retraining program for personal assistants to influence job environments and job satisfaction. The data were obtained from 330 personal assistants working at the Personal Assistance Association of Gyeonggi-do. The data were analyzed using the Structural Equation Modeling with relative effect analysis. The result of this study showed that self-efficacy and work ethics should have an impact job environments and job environments should have a positive impact job satisfaction. The retraining program for personal assistants showed a moderating effect on the relationship between work ethics and job environments. However, the findings did not support the moderator effect on the retraining program for personal assistants in the relationship between self-efficacy and job environments. Using these findings, social work administration agency, in particular, can be guided in terms of human resource management under social work administration.

Due to a rapidly expanding aging population, the incidence of degenerative bone disease has increased, and efforts to handle the issue using regenerative medicine have become more important. In order to control various bone diseases such as osteoarthritis and osteoporosis, regenerative medicine utilizing adult stem cells has been extensively studied. And it is now clear that the mitochondrial energy metabolism, oxidative phosphorylation, is important for the process of stem cell differentiation. Interestingly, a recent study reported that salicylate promotes mitochondrial biogenesis by regulating the expression of $PGC-1{\alpha}$ in murine cells. However, the possible effects of salicylate on osteogenic differentiation through increased mitochondrial biogenesis in stem cells remain unknown. Thus, here we investigated whether salicylate could influence osteogenic differentiation and mitochondrial biogenesis of periosteum-derived mesenchymal stem cells (POMSCs). We found that salicylate treatments of POMSCs undergoing osteogenic differentiation increased the activity of alkaline phosphatase, a well-known early marker of bone cell differentiation. In addition, we observed that mitochondrial mass was increased by salicylate treatments in POMSCs. Together, these results indicate that salicylate can enhance osteogenic differentiation and mitochondrial biogenesis in POMSCs. Therefore, the findings in this study suggest that small molecules augmenting mitochondrial function such as salicylate can be a novel modulator for osteogenic differentiation and regenerative medicine.

This study examined the effects of non - personality behavior of supervisors on the job exhaustion and organizational effectiveness of nurses. A survey in the form of a questionnaire was completed by 250 nurses working at three general hospitals located in Seoul and Gyeonggi from September 20 to October 31, 2014. The collected data were analyzed by frequency analysis, factor analysis, correlation, and linear regression analysis using the SPSS program. The results of the analysis were as follows. First, the effects of the non-personality behavior of supervisors on the job exhaustion of nurses were statistically significant. Second, the effects of non-personality behavior of supervisors on the organizational effectiveness of nurses were statistically significant in job satisfaction, organizational commitment, and organizational citizenship behavior. Third, the effects of job exhaustion on organizational effectiveness of nurses was statistically significant for job satisfaction, job exhaustion, and organizational citizenship behavior. Because the non-personality behavior of a supervisor can have a negative effect on the exhaustion of a nurse's job and the organizational effectiveness, there should be a wide range of human resources and effective task allocations in a hospital to reduce job burnout and increase job satisfaction. In addition, it is necessary for the boss to develop desirable leadership education, appropriate modeling, and reduce their negative influence in the workplace.

Of great importance in food safety culture are the values of an organization regarding food safety that combine the human and material requirements needed to produce safe and hygienic foods. In recent years, efforts have been made to improve the level of implementation of food safety management systems by improving certain cultural elements of food safety. This study investigated the current state of food safety culture in the HMR manufacturing sector. An anonymous survey of 46 HMR manufacturers of various sizes was conducted to evaluate the implementation status of HACCP prerequisite program and food safety culture. The perceived importance of food safety culture factors and their performance were also surveyed. Employees of HMR manufacturers who participated in this survey recognized that the participation of employees and leadership was the most important factor in ensuring food safety. Smaller enterprises are less aware of the importance of such organizational culture. The survey shows that food safety culture indicators in large companies are generally higher than those of small and medium enterprises. Especially, the manager's level of commitment to food safety, resources input, and education and training was significantly higher than that found at small companies (p=0.005). Among the food safety culture evaluation factors, it was found that education and training had significant influence on HACCP prerequisite program performance. Continued employee education and training on food safety and hygiene are important for HMR manufacturers to achieve HACCP certification standards.
