Objective: The purpose of this study is to show the effectiveness of performing squat exercises at various angles to show the maximum muscle activity of the Vastus Medialis Oblique (VMO) and Biceps femoris (BF). Design: Cross-sectional study. Methods: A total of seventeen healthy young adults (8 males and 9 females) voluntarily participated in the study. All subjects randomly performed three different squat variations as follows: A squat performed with the ankle joint at $0^{\circ}$ of incline, a squat performed with the ankle joint at $5^{\circ}$ of incline, and a squat performed with the ankle joint at $10^{\circ}$ incline. Muscle activity was measured using surface electromyography. Electrodes were placed on the VMO and BF to measure the muscle activity on the various ankle angles for comparison analysis. Results: There was a significant increase in bilateral VMO muscle activation at $10^{\circ}$ of incline compared to $0^{\circ}$ and $5^{\circ}$ (p<0.05). Greater increases in muscle activation and exercise effect was observed with increasing incline angles of the board. Changes in bilateral BF muscle activity were found; however, none were found to be significant. Conclusions: Bilateral VMO activity was found to be significant when the squats were performed at an ankle angle of $10^{\circ}$ of incline when compared to at an ankle angle of $0^{\circ}$ and $5^{\circ}$ of incline. Squats performed on an incline can be recommended as an effective method to facilitate lower extremity muscle activities.

This study analyzes key word networks of the papers which are published at Korean Journal of Social Welfare issued by Korean Academy of Social Welfare from 1979 to 2015. It aims at investigating the trends of social welfare researches in Korea by dividing the given period into two: 1979-2000 and 2001-2015. It shows the trends in three ways: methodologies, subjects, and intellectual structures. In order to identify intellectual structure, it calculate centrality indices basing on co-appearance frequency of key words. It also derives some values which explain relationship structure of key words by using pathfinder algorithm, and finally visualizes the intellectual structures by using the NodeXL program. Some implications of the findings of these analyses are discussed in the end.

Dual drug-eluting stents (DES) is a primary treatment method for coronary arterial diseases in current interventional cardiology practice. However, their pathological results according to the sequence of coating of drugs have not been reported yet. The peptide-dopamine dissolved in acetonitrile was coated onto the Chonnam National University Hospital (CNUH) stent using an electrospinning coating machine. For secondary coating (e.g., sirolimus coating, designated as SPS), sirolimus (SRL) and poly lactic-glycolic acid (PLGA) were mixed in tetrahydrofuran (THF), and the solution was then coated on the CNUH stent that had underwent the primary peptide coating using an electrospinning and spray technique. Next, the peptide-dopamine was coated on the SRL-PLGA coated stent (PSS). In this study, it was confirmed that endothelialization was promoted without being significantly affected by the coating order (SPS or PSS). The sequence of drug and peptide coating may affect the development of restenosis and PSS was effective in the prevention of restenosis compared to that of using SPS.

We conducted investigations of the information and welfare of cattle in Korea. The livestock housing of conventional cattle farms and organic cattle farms were open side wall type with winch curtain and used litter floor. The stocking density of conventional (ranging from $10head/m^2$ to $12.5head/m^2$) and organic cattle farms (ranging from $10head/m^2$ to $16.7head/m^2$) met the demand for conventional or organic standards, respectively. The galvanized plate and sunlight plate were used as the roof material in all of farms. Especially, additional areas were provided to produce forage or to improve animal welfare in organic cattle farms. Thus we believe that present data contribute to develop the animal welfare certification for cattle and to improve animal welfare in Korea.

This paper aims at analyzing the use REITs for improving housing welfare, especially focusing on affordable housing. To do this, firstly, current state and main problems of domestic housing welfare are analyzed, secondly, housing welfare system involving capital market and case study of affordable housing REITs in United State are examined. and thirdly, utilization schemes of REITs for improving affordable housing are analyzed. In the process of executing housing welfare, various systemic bases for attracting capital market are constructed. Under these systemic basis, affordable housing REITs such as Community Development Trust are operated. This scheme also can be applied in Korea. In the context, the structures of using management on commition REITs and the structure of using real estate fund are proposed.

Purpose: The purpose of this study is to analyze the elderly friendliness of the serious game for dementia prevention and to seek out the influence factors for enhance the friendliness. Research design, data and methodology: It measured the elderly friendliness of the serious game for dementia prevention, run with multi-touchscreens, for 300 elderly people using the Seoul-based General Social welfare centers located at Seoul, and participants evaluated the elder-friendliness of the serious game, by responding to a questionnaire survey. In addition, it analyzed the influence relationship between the elderly friendliness (EF) and the influence factors of the serious game, by setting the factors as the game level (GL), the demand of expectations for demand (DoE) and the prevention & usefulness of cognitive decline (PUCD). Results: the findings show that most of participants positively evaluated the EF of the serious game, regardless of their socio-demographic characteristics. Moreover, it can be found that the more the 'GL DoE and PUCD', the more the 'EF'. The EF was most strongly affected by DoE, followed by PUCD, and then GL Developing and running the serious game by actively reflecting such factors may be one of ways for enhancing the participation in the serious game for dementia prevention and facilitating the sustainable use of it.

For introduction of local autonomy system, local government enabled efficient supply of public service by local resident's request. Specially, local governments is doing effort of that organize various policy and a lot of budgets for social welfare promotion, but is interested relatively little in efficient use of social welfare finance and operation. According to these problem, this study measured efficiency of social welfare facility in local governments. The purpose of this analysis is to measure the efficiency of community welfare in local governments by data envelopment analysis(DEA), using data from 16 local governments in Korea. Input variance is GDP per capita in local, rate of welfare budget, rate of financial independence and local public official per 10,000 capita. Output variance is social welfare facility per 100,000 capita and park area per 1,000 capita, The results of the study are summarized as follows : First, There was differential in efficiency about social welfare facilities operation in local governments. 7 local governments(Busan, etc.) was an in efficiency. Second, some local governments(Incheon, etc.) must increase scale of input variance, and some local governments(Busan, etc.) must improve efficiency of input variance.

The purpose of this study was to examine the factors influencing the attitude toward the increasing role of private health insurance(PHI). In the Korea Welfare Panel Data 2007, a sample of 1,675 (adjusted by weight value: 1,607) respondents on an opinion on promoting PHI was used in the study. With independent variables including socio-demographic characteristics, health status, health-related behavior, and opinions on welfare service, ordered-probit model was used to analyze the attitude toward PHI. Negative opinion on the increasing role of PHI were responded by 54.6%(n=877) of the respondents, whereas 22.2%(n=373) were positive and 23.2%(n=357) were neutral. Old people, the better off, those with worse self-assessed health status, and those having an experience of health examination tend to have the positive attitude toward the increasing role of PHI. Women, those with chronic diseases or disorders and those who do not agree that comprehensive welfare benefits reduce work incentive showed negative attitude toward PHI. When comparing the needs for PHI before and after medical utilization, ex-ante need tends to strengthen the tendency to support private health insurance. This study will contribute to the discussion on the optimal mix of public and private health insurance in Korea by a better recognition of attitude toward PHI and health care system.
