Purpose - This study is to propose discriminative management strategies to long-term care facilities based on the empirical analysis after reviewing the effects of social support, perceived by long-term care facility employees, to service orientation. Research design, data, and Methodology - The research model designed social support, job stress, organizational commitment, and service orientation. The survey collected data from 453 customers in a long-term care facility in jeju. The SPSS 18.0 package was used for analysis. Results - First, social support for long-term care facility employees has a negative(-) effect to job stress. Test results, social support factors except appraisal support had a negative impact on job stress. Second, social support has a positive(+) effect to organizational commitment. Test results, informational support, tangible support and appraisal support had significant effects on organizational commitment. However, emotional support had a positive impact on affective commitment and normative commitment. Third, social support has a positive(+) effect to service orientation. Test results had a positive impact. Fourth, job stress has a negative(-) effect to organizational commitment. In the test results, employee's continuance commitment and normative commitment had significant negative effects in job stress. However, affective commitment had no significant impact. Fifth, job stress has a negative(-) effect to service orientation. Test results showed a negative impact. Conclusions - The study implies the following. First, that there should be a change in the social perception of long-term care facilities. 'Long-Term Care Insurance for The Elderly' was enacted to emphasize this responsibility for the elderly problems as a new system. Enactment of this Act was expected to improve the quality of life of the people by stabilizing the elderly life and reducing the burden of families. Therefore, long-term care facility system should be as efficient as possible for making plans for systematic and organizational support. Second, the efforts of facility managers to minimize job stress of employees is necessary. Accordingly, performing spontaneous work is required for a comfortable working environment and management. Third, the systematic education and training to employees for service oriented behavior of the facility will be required in the long term.

Purpose - This study examines the adverse press coverage that has increased in proportion to the remarkable growth of various kinds of franchise businesses in the food service industry. Today, the trust of franchisees in relation to their franchisor, and the maintenance of good relations between the two, has become a significant social issue. This study investigates relationship satisfaction and the long-term commitment between the franchisor and franchisee. Research design, data, methodology - We used a path analysis to investigate the relationship between justice and trust, trust and relationship satisfaction, justice and relationship satisfaction, trust and long-term commitment, and relationship satisfaction and long-term commitment. Structural Equation Modeling and a Sobel test were used to investigate the mediating effects of trust and relationship satisfaction. Data were collected from 237 Food Franchisees in Seoul and Gyeonggi Province in order to test the theoretical model and its hypotheses. Two research methodologies are generally used in the distribution management field. For this study, an empirical method was used. Results - A causal analysis was carried out to test if the research model has a sufficient fit index (for instance, χ² = 46.694, df = 10, p = .000, GFI = 0.946, AGFI = 0.850, RMR = 0.034, NFI = 0.966, CFI = 0.973), and the results showed that the model was sufficient, thus demonstrating the suitability of the research model. Each hypothesis had a positive influence, both on long-term commitment and relationship satisfaction. Justice with the franchisor had a positive influence on trust. Relation satisfaction cognized by franchisees was found to positively influence long-term commitment. The franchisee perception of justice in relation to the franchisor had no significant influence on long-term commitment. The study investigated the hypothesis that trust could mediate justice and long-term commitment, and that relationship satisfaction could also mediate long-term commitment Both trust and relationship satisfaction were found to be important for long-term commitment. Specifically, trust sub-factors and justice sub-factors influenced long-term commitment. Identification-based and knowledge-based trust were more important than calculus-based trust. Distributive justice was deemed more important than procedural justice; distributive justice should thus be strengthened. Conclusions - Both franchisor and franchisee were independent businesses. Evidently however, the franchisor could not ensure profit without long-term commitment from the franchisee. As for the success of the franchise business, the franchisor should carry out appropriate strategies leading to a satisfactory relationship. For example, transparency makes it possible to maintain and enhance trust and to improve relationship satisfaction. Just relations between franchisor and franchisee should make it possible to maintain and enhance the franchisee's trust. The franchisor should provide a variety of information with respect to the franchisee's business success. Finally, in order to improve the franchisee's long-term commitment, the franchisor should ensure a just approach with trust and relationship satisfaction among their strategies.

After the 1970s, the importance of underground transmission systems increased and the construction rate of underground transmission lines also showed increasing trends each year, especially in metropolitan areas. Accordingly the social ripple effects are very large and wide when the fault occurs in underground power system, and the amount of time and money spent to restore the system also increases. So we must ensure stable operation and long-term reliability of the facilities. In Korea's case, long-term reliability tests for EHV power cables and accessories progressed poorly because equipment was not compatible for long-term reliability tests. Therefore we planned to construct a long-term reliability test field for EHV underground cables in order to ensure international quality reliability and optimal power cable operation techniques. The Gochang Underground Cable Test Field is under construction, funded by the Korean government, the govenment's union investment department, KEPCO, KERI and three private cable corporations. This project began in March, 2005 and will be completed by February, 2010. It is designed to promote joint research by incorporating several types of test equipment, construction of operating facilities, and being an internationally certified authority.

The long-term settlement characteristics for the cast-in-place bored pile in the deep-thick soft soil are investigated by post-grouting field tests. Six cast-in-place bored engineering piles and three cast-in-place bored test piles are installed to study the long-term settlement characteristics. Three post-grouting methods (i.e., post-tip-grouting, post-side-grouting, and tip and side post-grouting) are designed and carried out by field tests. Results of the local test show that decreased settlements for the post-side-grouted pile, the post-tip-grouted pile and the tip and side post-grouted pile are 22.2%~25.8%, 30.10%~35.98% and 32.40%~35.50%, respectively, compared with non-grouted piles. The side friction resistance for non-grouted piles, post-side-grouted pile, post-tip-grouted pile and the tip and side post-grouted pile undertakes 89.6~91.3%, 94.6%, 92.4%~93.0%, 95.7% of the total loading, respectively. At last, the parameters back analysis method and numerical calculation are adopted to predict the long-term settlement characteristics of the cast-in-place bored pile in the deep-thick soft soil. Determined Bulk modulus (K) and a creep parameter (Ks) are used for the back analysis of the long-term settlement of the post-grouted pile. The settlement difference between the back analysis and the measurement data is about 1.11%-7.41%. Long-term settlement of the post-grouted piles are predicted by the back analysis method, and the predicted results show that the settlement of the post-grouted pile are less than 6 mm and will be stable in 30 days.

This study was carried out to investigate the changes of physical and chemical properties and the usability of long-term stored leaf tobacco. The physical chemical properties of the flue-cured and burley leaves produced in 1993, processed in 1994 were analysed from Nov. 1996 to Nov. 1999. The pH and moisture content in leaf decreased slowly until 4 years’storage after processing, while those of leaf changed little thereafter. However, total sugar content continuously decreased until 5 years after processing. The filling capacity increased and shatter resistance index decreased in long-term stored leaf. The sensory test, cilia stasis and the chemical components of cigarette smoke had no significant differences between short and long-term stored leaves. When the processed leaves were stored till 5 years after processing, there were no deteriorative effects on quality and usability of leaf tobacco. Therefore, it is considered that the processed leaf may be stored for 5 years or more under the inevitable situation.

PURPOSES: The purpose of this study is to evaluate physical properties, durability, fatigue resistance, and long-term performance of poly-urethane concrete (PU) which can be possible application of thin layer on long-span orthotropic steel bridge and to check structural stability of bridge structure. METHODS : Various tests of physical properties, such as flexural strength, tensile strength, bond strength and coefficient of thermal expansion tests were conducted for physical property evaluation using two types of poly urethane concrete which have different curing time. Freezing and thawing test, accelerated weathering test and chloride ion penetration test were performed to evaluate the effect of exposed to marine environment. Beam fatigue test and small scale accelerated pavement test were performed to assess the resistance of PU against fatigue damage and long-term performance. Structural analysis were conducted to figure out structural stability of bridge structure and thin bridge deck pavement system. RESULTS: The property tests results showed that similar results were observed overall however the flexural strength of PUa was higher than those of PUb. It was also found that PU materials showed durability at marine environment. Beam fatigue test results showed that the resistances of the PUa against fatigue damage were two times higher than those of the PUb. It was found form small scale accelerated pavement test to evaluate long-term performance that there is no distress observed after 800,000 load applications. Structural analysis to figure out structural stability of bridge structure and thin bridge deck pavement system indicated that bridge structures were needed to increase thickness of steel deck plate or to improve longitudinal rib shape. CONCLUSIONS: It has been known that the use of PU can be positively considered to thin layer on long-span orthotropic steel bridge in terms of properties considered marine environment, resistance of fatigue damage and long-term performance.
