The Oriental thought does not stay in self, society, or state, but goes further to expand its bounds as "Chunha(the World, 天下)", which is not just the spacious expansion but the moral expansion. It provides a clue to overcome the limitations of the Western international political thought resulting in nationalistic tendencies. Such a cosmopolitcan orientation in the East can be found in the concepts of "Wangdo(Just Way, 王道)", "Yinjung(Benevolent politics, 仁政)", which make Hua(harmony, 和) its essential characteristics. If the East Asian community is formed, it should be based on universal principles that all East Asian citizens can sympathize with from below, not in a one-sided and coercive way. In this regard, the formation of "Sahaeyilga(四海一家, We are the world)", the "Chunha天下" based on the philosophy of the peace seeking 'similarity' in 'difference', can provide philosophical clues to resolve the conflicts and contradictions of the current isolationalist and confrontational international situation.

Since the fiber reinforced polymeric (FRP) composites are considered in next generation of space transportation systems, reliable thermal expansion properties should be well provided for structural design of composite materials. To obtain accurate mechanical behaviors at a cryogenic temperature, precise strain measurement and calibration must be provided. In this work, apparent strains (or thermal output) of temperature self-compensated strain gages were deliberately investigated for epoxy, CTBN modified epoxy and carbon fabric composite system from room temperature to liquid nitrogen temperature. Also, fourth-order thermal output curves were presented for the further calibration. The results showed that the thermal output is heavily dependent on test materials and a large amount of apparent strains were observed for the polymer resins.

This study attempts to evaluate the beneficial equity and operational efficiency of the three Korean medical insurance programmes and thereby suggest directions for their policy improvement. Concepts of the equity and effciency were reviewed to develop indicators for comparative analysis. For the analysis, statistical and financial accounting data for 1991, issued by the National Federation of Medical Insurance and the Korea Medical Insurance Corporation, on the operational status and performances of the programmes, were collected and rearranged to be suited to the purpose of the study. The analysis reveals that beneficial inequity exists between self-employed and employee programs. and that operational inefficiency is prominent in both programms for self-employeds and for Government employees and private school teachers. In order to improve the beneficial inequity of the self-employed program, it is suggested that policies be formulated and implimented toward increasing the program revenue through increasing subsidies from the Government, and through inter- program finance adiustment. For the operational inefficiency of the two programs, it is judged that, toghether with the administrative support and control from the Government and the insurance society bodies, self- efforts be initiated to improve the internal mangement styles and systems of the insurance societies. Finally, from the viewpoint of the structural efficiency, expansion of the preventive insurance benefits by the insurance soceties is recommended both for beneficial equity and operational efficiency.

Objectives : The purpose of the study is to investigate the recognition between laypersons and dental hygienists on expansion of health insurance of scaling. Methods : A self-reported questionnaires was filled out by 100 laypersons and 100 dental hygienists from October 7, 2013. Data were analyzed by SPSS version 21.0 program. Results : All the dental hygienists recognized the introduction of the health insurance of scaling and 71.0% of the laypersons agreed. The introduction of health insurance of scaling was responsible for the interest toward scaling in 80 dental hygienists(80.0%) and 66 laypersons(66.0%). 94% of dental hygienists answered that health insurance of scaling would prevent periodontal diseases. The expansion of health insurance of scaling revealed many periodontal diseases and 52% of laypersons answered that prevention of periodontal diseases would deprive the dental hygienists of their jobs. Conclusions : The expansion of health insurance of scaling can prevent the periodontal diseases and enhance the oral health services. So the government must try to expand the health insurance of scaling.

Hydrogen engine with homogeneous charged compression ignition can achieve high efficiency by high compression ratio and rapid chemical reaction rates spatially. However, it needs to expansion of the operation range with over-all load conditions which is very narrow due to extremely high pressure rise rate. The adoption of the lean boosting in a HCCI $H_2$ engine is expected to be effective in expansion of operation range since minimum compression ratio for spontaneous ignition is decreased by low temperature combustion and increased surround in-cylinder pressure. In order to grasp its possibility by using lean boosting in the HCCI $H_2$ engine, compression ratio required for spontaneous ignition, expansion degree of the operation range and over-all engine performance are experimentally analyzed with the boosting pressure and supply energy. As the results, it is found that minimum compression ratio for spontaneous ignition is down to the compression ratio(${\varepsilon}$=19) of conventional diesel engine due to decreased self-ignition temperature, and operation range is extended to 170% in term of the equivalence ratio and 12 times in term of the supply energy than that of naturally aspirated type. Though indicated thermal efficiency is decreased by reduced compression ratio, it is over at least 46%.

Mesenchymal stem cells (MSCs) have the ability to self-renew and differentiate into multi-lineage cells, thus highlighting the feasibility of using umbilical cord blood-derived MSCs (UCB-MSCs) for cell-therapy and tissueengineering. However, the low numbers of UCB-MSC derived from clinical samples requires that an ex vivo expansion step be implemented. As most stem cells reside in low oxygen tension environments (i.e., hypoxia), we cultured the UCBMSCs under 3% $O_2$ or 21% $O_2$ and the following parameters were examined: proliferation, senescence, differentiation and stem cell specific gene expression. UCB-MSCs cultured under hypoxic conditions expanded to significantly higher levels and showed less senescence compared to UCB-MSCs cultured under normoxic conditions. In regards to differentiation potential, UCB-MSCs cultured under hypoxic and normoxic conditions both underwent similar levels of osteogenesis as determined by ALP and von Kossa assay. Furthermore, UCB-MSCs cultured under hypoxic conditions exhibited higher expression of OCT4, NANOG and SOX2 genes. Moreover, cells expanded under hypoxia maintained a stem cell immnunophenotype as determined by flow cytometry. These results demonstrate that the expansion of human UCB-MSCs under a low oxygen tension microenvironment significantly improved cell proliferation and differentiation. These results demonstrate that hypoxic culture can be rapidly and easily implemented into the clinical-scale expansion process in order to maximize UCB-MSCs yield for application in clinical settings and at the same time reduce culture time while maintaining cell product quality.

As OTT services become popular worldwide, content IP expansion strategy has an important position in the platform media industry ecosystem where new content is constantly distributed. In particular, the method in which a successful narrative expands the elements constituting a specific world, that is, the Universe, is effective in reducing risk factors in content IP expansion and expanding content franchises. This study intends to examine how Marvel's cinematic Universe (MCU) is strategically performing content IP expansion while borrowing the multiverse concept and replicating and reproducing it by itself through narrative analysis of . As a result, the multiverse can reproduce an incomplete state by repeating the completed event, which can exist as another self-fulfilling content. At the same time, it can be an effective content IP expansion strategy in that each story can be produced because a single character can exist in multiple under the multiverse.

Purpose: This study aimed to investigate the degree of role conflict and its ambiguity, and fatigue in clinical nurses and to analyze the effect of these on their self-resilience in order to provide fundamental data for improving their working environment after the Middle East Respiratory Syndrome outbreak. Methods: After the collection of data from 258 clinical nurses in five general hospitals, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression were performed using IBM SPSS Statistics 20.0. Results: A significant positive correlation was found between nurses' role conflict and ambiguity and fatigue; while a negative correlation was found between nurses' role conflict and ambiguity and self-resilience. A significant negative correlation was found between fatigue and self-resilience. According to the study results, the factor that affected clinical nurses' self-resilience the most was role conflict and its ambiguity, followed by marital status, fatigue, educational level, religion, and related tasks, which together accounted for 38% of self-resilience in clinical nurses. Conclusion: To improve weaknesses in nursing care after the Middle East Respiratory Syndrome outbreak, the scope of nursing care was changed upon the expansion of integrated nursing and care-giving services. Therefore, in the rapidly changing environment of nursing, policies to improve nursing performance, as well as successful reaction capability, are suggested.

Hemodialysis (HD) patients face a common problem of malnutrition due to poor appetite. This study aims to verify the appetite alteration model for malnutrition in HD patients through quantitative data and the International Classification of Functioning, Disability, and Health (ICF) framework. This study uses the Mixed Method-Grounded Theory (MMGT) method to explore various factors and processes affecting malnutrition in HD patients, create a suitable treatment model, and validate it systematically by combining qualitative and quantitative data and procedures. The demographics and medical histories of 14 patients were collected. Based on the theory, the research design is based on expansion and confirmation sequence. The usefulness and cut-off points of the creatinine index (CI) guidelines for malnutrition in HD patients were linked to significant categories of GT and the domain of ICF. The retrospective CIs for 3 months revealed patients with 3 different levels of appetite status at nutrition assessment and 2 levels of uremic removal. In the same way, different levels of dry mouth, functional support, self-efficacy, and self-management were analyzed. Poor appetite, degree of dryness, and degree of taste change negatively affected CI, while self-management, uremic removal, functional support, and self-efficacy positively affected CI. This study identified and validated the essential components of appetite alteration in HD patients. These MM-GT methods can guide the selection of outcome measurements and facilitate the perspective of a holistic approach to self-management and intervention.
