The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 3 to March 3 to March 30, 2010 through survey questionnaires. The main results of this study were as follows: 1. The commitment level of the subjects according to their satisfaction was higher when the administrators both in Private hospitals and Public hospitals were not satisfied in their works. 2. The commitment level of the subjects according to the subjects' job dedication level was higher those who had higher emotional attachment to their job in all vocations in both Private hospitals and Public hospitals. 3. The commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all vocations in both Private Hospitals and Public Hospitals. 4. From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In Private hospital employees, those who had senior officer posts in labor union and higher normative commitment showed higher commitment union. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as colleagues attitudes is important determinant in union commitment, hospital managers should have countermeasures to enhance the work atmosphere of hospital employees.

Purpose: The aim of this study is to identify the legal concept of a license and a qualification for health care personnel. We analyze the appropriateness of the qualification for the first-class paramedics and the sufficiency of 3-year job experience in substitution for college level academic major. Method: We reviewed Laws on Healthcare which stipulate academic and career qualifications for healthcare personnel for whom college-level academic training and job experience to get a license. Results: There is no legal consideration which permits major and educational background substituted by job experience. Only third-class hygienist who graduated from a high school or the equivalent with 3 year job experience can apply for first-class hygienist' national license examination without educational requirements. However, it is nothing to compare with first-class paramedics because the work of hygienist is not directly related to patients care and there is no need of doctor's supervision for hygienist' job. Paramedics have a major role in saving emergency patients in making prompt decision, applying appropriate emergency treatment, securing intravenous route, managing intubation, applying defibrillator, and etc. Conclusion: Ministry of Health & Welfare should grant license to paramedics and annul replacement of academic major background. In addition, it is imperative to broaden the scope of paramedics' job so that they can guarantee patient's life saving in emergency situation with quality major curriculum of college level.

South Korea, which has seen economic growth at a rapid pace and the number of the old people on the rise, is facing challenges, including social problems resulting from the aged society, lack of work force supporting the elderly and needs of renewing residential environment for them. The old people in the process of senility are forced to experience a wide range of physical, mental and social difficulties and problems when they are living in existing houses. This study was conduced with a sample group consisting of the elderly who were living in detached places of multiplex houses and a plane which was developed as a tool for a workshop, the one that is a collective residence model, also known as one of an alternative housing for the old in the future. This study finds that in order to get rid of negative images of the collective residence for the old, residence surroundings for the aged should be created not as uniform space formation but as aging-in-place, and specifically, considering that the quality of life for the aged remains to continue is needed. Findings can be a reference to create ideas of developing residential environment for the aged.

The European Union has an active rural development policy because this helps us to achieve valuable goals for our countryside and for the people who live and work there. Rural development policy involves the cofinancing by the EU and Member States of a variety of measures. Member States decide on the most appropriate measures for their rural areas from a menu of measures proposed at EU level. There are 18 Leader+ programs in Spain. Program supports Local Action Groups which are located in two or more autonomous regions. The Valle del Jerte, located in the northwest of the province of Caceres is one of the districts making up what is known as the Alta Extremadura. The rural development strategy in this area is to overcome the great deficits of the rural world, prevent rural exodus by improving the quality of life of the population,and improve the soicoeconomic environment of the district in order to help create jobs and improve family incomes. Specifically they try to create a mechanism to improve involvement, communication and social cohesion in the district, with a view to improving the internal structure of organizations and establishing rural channels for cooperation between district institutions for integrated development of the district.

$WS_2$ particles were added to micro-diamond blades with Cu/Sn binding metal as lubricants to improve cutting efficiency. It was found in previous works that the added $WS_2$ lubricant could reduce remarkably the momentary energy consumption during dicing tests but increased wear rate slightly owing to weak bonding between lubricant particles and bond metals. In the present work, the surface of $WS_2$ lubricant particles were etched for activating the surface of $WS_2$ particles that provide even distribution of particles during powder mixing process and improvement of wetting at the interfaces between $WS_2$ particles and molten Cu/Sn bond metals during pressurized sintering so that could provide the improved strength of micro-blades and result in extended life. Chipping behavior of workpiece with the types of micro-blades including $WS_2$ were compared because it is important in semiconductor and micro-packaging industries to control average roughness and straightness of sliced surface which is closely related with quality.

In contemporary housing design, this cultural value has been ignored. Contemporary design has adapted quickly to global trends and houses have gradually lost their cultural identity (GhaffarianHoseini & Dahlan, 2012; Lim, 2001). Nevertheless, traditional housing culture persists in people's behavior and thoughts. Therefore, there is currently a pressing need to rebuild cultural identity in housing for cultural sustainability. This study aimed to analyze the traditional culture which was maintained, then transformed and disappeared in housing design through the quantitative survey and explore the cultural identity of Malaysian housing as a result. A quantitative survey was distributed to mothers of 129 married households living in a metropolitan area of Kuala Lumpur in August 2019. As a result, it was found that hosting guest was important even though the designated space (serambi) was disappeared. The LD/K layout, separating kitchen from living and dining area was philosophical and practical culture, still strong among older generation, but weakened among younger generation. To accommodate the traditional habit of diverse household work, wet kitchen, utility space for washing machine & drying, and outdoor space were needed to design carefully. When applied to future housing design, the findings will contribute to enhancing quality of life by strengthening residents' sense of place and social cohesion and by providing a culturally inherent design that eases the effects of globalization.

Titanium alloy has been widely used in the aerospace industry because of its high strength and good corrosion resistance. During cutting, the low thermal conductivity and high chemical reactivity of titanium generate a high cutting temperature and accelerates tool wear. To improve cutting tool life, cryogenic machining by using a liquid nitrogen (LN2) jet is suggested. In cryogenic jet cooling, evaporation of LN2 in the tank and transfer tube could cause pressure fluctuation and change the cooling rate. In this work, cooling uniformity is investigated in terms of liquid nitrogen jet pressure in cryogenic jet cooling during titanium alloy turning. Fluctuation of jet spraying pressure causes tool temperature to fluctuate. It is possible to suppress the fluctuation of the jet pressure and improve cooling by using a phase separator. Measuring tool temperature shows that consistent LN2 jet pressure improves cryogenic cooling uniformity.

Purpose: The purpose of this study was to identify the influence of nursing practice environment, compassion fatigue and compassion satisfaction on burnout among clinical nurses in Korea. Methods: A descriptive crosssectional study was conducted. The sample consisted of 210 clinical nurses from three tertiary hospitals located in Seoul. Measurement instruments included the Korean version of the Practice Environment Scale of Nursing Work Index (K-PES-NWI) and Stamm's professional quality of life (ProQOL). Descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression were used to analyze the data. Results: Nursing practice environment had moderate negative influence on burnout (r=-.38, p<.001). Compassion fatigue had strong positive influence on burnout (r=.50, p<.001), while compassion satisfaction had strong negative influence on burnout (r=-.61, p<.001). The regression model explained 63% of variance of burnout and the compassion satisfaction was the most influencing factor for nurses' burnout. Conclusion: This study identified nursing practice environment, compassion fatigue and compassion satisfaction as influencing factors for nurses' burnout. Strategies to decrease compassion fatigue, enhance compassion satisfaction and create better nursing practice environment are recommended to decrease nurses' burnout.
