With the increase in family income in Korea and the improving quality of life, there is a rapid growth in the restaurant industry. Therefore there is a demand for quality service in this industry. This paper reviews the relationship between service quality and the degree of employee empowerment. The first objective of this research is to test the effects of employee empowerment on service quality, and the second one is to test how tenure affects this relationship. According to statistical analysis, meaning, competency, and autonomy generally have an affirmative impact on many service quality factors. Also the results of regression analysis to test the moderation effect show that long term employees are more sensitive to autonomy than short term employees.

Estuary reservoirs were artificial reservoir with seawalls built at the exit points of rivers. Although many water resources can be saved, it is difficult to manage due to the large influx of pollutants. To manage this, it is necessary to analyze watersheds and reservoirs through accurate modeling. Therefore, in this study, we linked the Hydrological Simulation Program-FORTRAN (HSPF), Environmental Fluid Dynamics Code (EFDC), and Water quality Analysis Simulation Program (WASP) models to simulate the hydrology and water quality of the watershed and the water level and quality of estuary lakes. As a result of applying the linked model in stream, R² 0.7 or more was satisfied for the watershed runoff except for one point. In addition, the water quality satisfies all within 15% of PBIAS. In reservoir, R² 0.72 was satisfied for water level and the water quality was within 15% of T-N and T-P. Through the modeling system, We applied upstream pollutant management scenarios to analyze changes in water quality in estuary reservoirs. Three pollution source management were applied as scenarios, the improvement of effluent water quality from the sewage treatment plant and the livestock waste treatment plant was effective in improving the quality of the reservoir water, while the artificial wetland had little effect. Water quality improvement was confirmed as a measure against upstream pollutants, but it was insufficient to achieve agricultural water quality, so additional reservoir management is required.

Since the opening of the Shin-Kori #1,2 in 2005, fly ash mixed concrete has been used for NPP concrete structures under construction in Korea with the aim of preventing aging and improving durability. In this paper, the quality suitability of fly ash manufactured in Korea is assessed and the basic physical properties of fly ash mixed concrete and its durability against primary causes of aging are verified through experimental methods. Because of the internal structure filling effect from the pozzolanic reaction of fly ash and the resulting improvements in mechanical performance in such areas as strength and salt damage resistance, the durability of fly ash mixed concrete is shown to be superior. It is judged that this result can be applied in measures not only for improving the safety of NPP structures in operation in Korea but also for implementing effective structure life management should extending the life of structures be needed in the future.

Objectives: The purpose of this study was to investigate patients' demand for music and art therapy in the treatment of Parkinson's disease and to understand how patients view the use of music and art therapy as a complementary form of treatment that can improve their quality of life and increase their self-efficacy in addition to medication. Methods: To this end, 60 Parkinson's patients visiting Daejeon Korean Medicine Hospital at Daejeon University were surveyed about music and art therapy. Results: The survey demonstrated a highly positive response to the music program, with strong belief in its efficacy for Parkinson's disease and significant interest in participation. Group music therapy was perceived as effective for enhancing mental health, respiratory function, language disorders, and overall quality of life. Although the art program was also deemed effective, patients showed slightly lower interest and willingness to participate compared to music therapy. The patients preferred 60-minute sessions once a week for about 8 weeks. Conclusions: We propose the following directions for a Parkinson's music and art therapy program. First, develop a once-a-week, 8-week music and art program for Parkinson's patients. Second, design the music program to focus on improving respiratory function and quality of life. Third, the art program focuses on creating a sense of security and comfort through emotional exchange among patients and improving self-efficacy.

Purpose: The purpose of this study was to analyze the trend of research on the use of home-based pulmonary rehabilitation. Method: Using Medline and CINAHL search engine, experiemental research, titled as 'home-based pulmonary rehabilitation' and 'chronic lung disease', statistics were collected. The total 29 experimental studies published between 1981 to 2000 were selected and analyzed according to the ATS guidelines. Result: 1) The study samples in research were mostly of men, whose lung function was moderate to severe. 2) The total period of the intervention program varied from 5 to 12 week. The program included excercise intervention and educational intervention. Psychosocial intervention was minimal. 3) The outcome of the home-based pulmonary rehabilitation had been measured mostly by physical aspects. Quality of life and cost were less frequently measured. 4) In terms of effectiveness of the home based pulmonary rehabilitation program, physiologic outcome, such as lung function and hematologic markers, there was more 'no effect' than 'positive effect', whereas there was more 'positive effect' in decreasing dyspnea, improving excercise capacity, and improving quality of life. Conclusion: Based on these findings, future research on home-based pulmonary rehabilitation should be emphasized and provide standardized protocol, including psychosocial intervention, and analyses on cost and quality of life.

This study was carried out to investigate the possibility of improving the texture and the flavor of Dasik made of the Omija extract, various sugars and rice powder. Sensory quality and mechanical characteristics of Dasik were compared. The moisture content of the Croup of tile Dasik added with Omija extract was higher than that with non-Omija extract The Omija Dasik containing molasses showed the highest value (23.5%) in moisture content. In sensory quality, Omija Dasik containing honey and symp showed the highest score in overall acceptability (6.2 and 6.0, respectively). The Rice Dasik containing syrup showed the highest values in lightness (L) and yellowness (b) in color. The Omija Dasik containing syrup showed the highest values in redness (a) in color. The Dasik added with honey and syrup were lower in hardness, but higher in cohesiveness, springiness, gumminess and brittleness of textural characteristics. When sensory quality and mechanical characteristics of the Dasik were compared with, the gumminess and brittleness in mechanical characteristics were positively correlated with the appearance and the taste acceptability in sensory quality (p<.01, p<.05). The springiness was negatively correlated with the tooth packing in sensory quality (p<.001). The Omija Dasik was more desirable in flavor, taste and overall acceptability, especially those added with honey and syrup. From the above results, the honey might be replaced by the less expensive syrup, when making the Omija Dasik.
