This study analyzed the structural elements of transformational leadership on hotel employees job satisfaction and organizational identification, and inquired into how moderating variables such as demographical characteristics and the features of hotels affect transformational leadership. The ultimate purpose of this study was to provide managerial implications to hotel business operators and hotel employees. The main results of this study are as follows; According to the result of factor analysis on transformational leadership and hotel employees job satisfaction, 18 variables were derived as two factors 'obliging leadership' & 'vision leadership' factor in the area of transformational leadership, and 31 variables were derived as four factors 'welfare and work environment', 'ability display and job stability', 'colleague relationship and job performance' and 'company policy' factor. Second, stepwise regression analysis on whether the type of transformational leadership at hotels has a significant effect on employees job satisfaction & organizational identification, 'vision leadership' and job satisfaction and the both 'vision leadership' & 'obliging leadership' among the types of transformational leadership appeared to have a significant effect on hotel employees organizational identification. Third, One-Way ANOVA and t-test in order to examine significant difference in the type of transformational leadership according to demographical characteristics and general characteristics, statistically significant difference was found according to income level, the current position, work experience, the type of hotel operation and the experience of job change.

In this study, we analyze the relationship between long-term care workers' emotional labor, professional quality of life, and service quality. The subjects of this study were 211 long-term care workers working in long-term care facilities. Self-administered questionnaires were used. In the research model, emotional labor(surface behavior, internal behavior) was verified using independent variables, with professional quality of life (compassion satisfaction, compassion fatigue) as the parameters and service quality as the dependent variables. The results of this study are as follows. First, the fit of the model was good. Second, the direct effects of emotional labor on service quality were not significant. However, there was a positive correlation between internal behavior and service quality, and a negative correlation between surface behavior and service quality. Third, professional quality of life(empathy satisfaction) was the most influential variable in terms of service quality. The results of this study demonstrate the necessity to payclinical and academic attention to long-term care workers' emotional labor and quality of life.

As the post-cold war era and globalization go on, national security problems which were not traditional national security problems such as terrorism, crime, environmental disasters, economic crises, cyber-terrorism, diseases, and energy problems threat humanity and nations and demands changes. Also, with the change, the concept of "big government" has emerged as the role of nation expanded. The modern society sees every country change from small government to big government in order to realize the establishment of welfare state. A comprehensive interpretation of security is needed in order to comprehensive protection of citizens beyond outside invasion such as crime, new disaster, terrorism. In Korea, incidents such as Cheonan-Ham, Yeonpeyong-Do, foot-and-mouth disease, Ddos terrorism, pirates hostages, mad cow disease, AI are happening and the humanitarian support for North Korea and the summit of South and North Korea are at a standstill. Also, National emergency management system, comprehensive emergency management center, countrol tower, national security system, cooperation with citizens, establishment of legal and institutional system are needed. The importance of this research is on the reestablishment of new national security and emergency management system according to the comparison between the national security and counter-terrorism system of Korea and that of the United States which is a leading country in this field. Also, the establishment of national emergency management act is needed as a statute for effective function as currently various laws and administrative organizations are dispersed.

This study is to analyze the performance of SWH(Solar Water Heating) and GSHP(Ground Source Heat Pump) systems by evaluating their energy efficiency and LCC(Life Cycle Cost) as being applied to the OO hall as a selected building in the Army. The OO hall, used as bathrooms, dining rooms, accommodations and offices, has reinforced concrete structure system with three floors above the ground and one underground, and its total floor area is approximately 2,917$m^2$. Two energy simulations are conducted to predict the yearly cooling and heating energy of the selected building: One is for analysis of an air-conditioning energy consumption using the e-Quest program, and another is for two new-renewable energy facilities as a water heating source using the RETScreen. The installed capacity of two new-renewable energy facilities is determined according to the 5% level of total standard construction cost. As a briefly result, SWH system is more energy-effective than GSHP system. Considering the break-even point, it is expected that SWH can take only 3 years 11 months to pay for itself in savings while the investment of GSHP can be recovered in more than 16 years 6 months.

Objectives : This study looked at the effects of chronic IPV on suicide ideation among married women in the country. Methods : This study used data from the five-year-old Korea Welfare Panel and analyzed using questions about verbal and physical violence, depression and suicide ideation that were investigated every year. Age, education, and economic levels, drinking, religion, chronic disease, satisfaction with family relationship, satisfaction with social relationship, were included as variables. Results : The five-year cumulative score of verbal violence had a statistically significant effect on the depressive symptom, and the relative risk was 1.180. The relative risk of five-year-old cumulative score of verbal violence in suicidal ideation was 1.276, and it was also significant even if they exclude the effects of depressive symptom. On the other hand, the five-year cumulative score of physical violence was found to have no significant impact on suicide ideation if they excluded the effects of depressive symptom. Conclusions : Unlike previous studies, this study found that chronic verbal IPVs increase suicide ideation, even though they do not contain effects of depression. Such findings suggest that intervention in IPV in married women may help reduce the nation's suicide rate.

Korea is expected to enter 'Super Aged Society' in 2026. However, as walking is the very basic human right of mobility, securing safe and convenient moving of elderly people comprising the majority of transportation vulnerable is thought to be the most basic welfare, which can be easily neglected. From this perspectives, this study provides the walking characteristics of elderly people to be used in design of pedestrian facilities. The analysis of the measurements using Motion Analysis Systems shows that all walking factors of elderly people is 75% level of the younger group. Elderly group shows slower movement, reduced shoulder movement and increased ankle movement compared to the others. Also, foots are risen less and ground repulsive force is increased. Cluster analysis shows that the group of the elderly shows high variability inside the group, and 2 or 3 clusters can be formed with factors of Walking, Balance and Muscles. These walking characteristics can be used in designing pedestrian road, slope and step height of roadway facilities.

The purpose of this study was to test characteristics between normal and autistic children via comparison of nutrient intakes, hair mineral, blood free radical, and serotonin contents. A total of 50 children aged 3-9 were divided into two main groups of normal control children (n=22) and autistic children (n=28) tested by child psychiatrist. The nutrient intakes by 24-hour recall method were no significantly different between the two groups. The concentrations of toxic mineral, such as cadmium (Cd) and lead (Pb) in hair of autistic children were significantly higher, while concentration of antioxidant mineral (Cu, Zn, Fe) was lower than that of normal children. The autistic children had significantly higher concentrations of blood free radical than that of normal children. No significant difference was observed in serotonin concentration between the two groups. Our results suggest a possible role of increased toxic mineral and free radical, both of which may be relevant to the pathophysiology of autism in children with developmental delay.

The Terrestrial DTV service compliant with ATSC has been advancing for years. In KBA(Korean Broadcasters Association), a multi-channel service was broadcasted on air during the period of the 2006 FIFA World Cup Germany with the various type of MMS(Multi Mode Service) using MPEG-2 encoding method. MMS Service can provides not only one HD channel but also serveral additional services within 6MHz bandwidth. Using digital video compression technology(MPEG-2), many various programs such as HDTV, SDTV, Audio and Data are able to be transmitted within the same bandwidth. From November 2009, KBS has been preparing an advanced MMS service, 'Korea-View' which has both methods of encoding, MPEG-2 and H.264 that is compliant ATSC mobile standard, A/153. Korea-View is a kind of multi-channel broadcast service to provide one HD and 3 SD programs with the bandwidth of 6MHz. Terrestrial multi-channel service is required to focuse on expanding viewer service. Such Terrestrial multi-channel services will contribute to transferring to digital broadcasting and to extending the viewers' welfare. Due to advances in digital technology, Pay-TV channels has increased to hundreds. Even though digital switchover is being proceeded, terrestrial broadcasters have been unable to deliver multi-channel services. In this paper, technical features and differences of MMS and Koreaview will be analyzed regarding terrestrial multi-channel broadcasting services, and the politic direction will be proposed in accordance with introduction of future service.

Objectives : We investigated the effects of fermented soybean(FSOB) on body weight and examined whether hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, FSOB(1), (2) and (3). After mice were treated with FSOB for 9 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Results : 1. Compared with controls, FSOB-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in FSOB(3) and FSOB(1). 2. Compared with controls, FSOB-treated mice had lower feeding efficiency ratio and blood plasma leptin levels, the magnitude of which was prominent in FSOB(3). 3. Compared with controls, FSOB-treated mice had lower blood plasma total cholesterol and LDL-cholesterol levels. 4. Blood plasma AST and ALT concentrations were not changed by FSOB, indicating FSOB do not show any toxic effects. 5. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by FSOB, whereas the adipocyte number per unit area was significantly increased, suggesting that FSOB decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by FSOB. Conclusions : These results demonstrate that FSOB effectively reduces body weight gain, feeding efficiency ratio, blood plasma leptin level and improves hepatic lipid accumulation.
