Purpose: This study has been conducted in order to examine the oral health status and dental prostheses status, and the effects of dental prostheses to the oral health related quality of life among the elderly using social welfare centers. Material and methods: For this purpose, the researcher conducted a questionnaire survey and oral examination of 275 samples of old persons using 7 social welfare centers located in Daejeon metropolitan city. The oral health related quality of life was measured by GOHAI (Geriatric Oral Health Assessment Index). Results: 1. The less age and the more education and the more subjective economic status and living with spouse of family status, the higher GOHAI showed. 2. Mean age of first using of removable denture is 62.11 years old and average life cycle of removable denture is 10.76years. 57.5% of study subjects use removable denture and complete denture user of study subjects are 13.8%. 3. In the case that they use fixed prostheses rather than removable ones and in the complete denture they use both sides (upper and lower) rather than single side, showed higher GOHAI. 4. In the case that they showed higher degrees of satisfaction with dental prostheses and can use them always and showed no necessity for new dental prostheses and denture adaptation is good, GOHAI showed higher. Conclusion: In order to improve oral health related quality of life among the elderly who have many missing teeth, it is required to restore their masticatory ability to the normal level by restoring the missing teeth which has lost its function through providing proper dental prostheses.

The evaluation of students and employees on the importance and the performance for sanitary characteristics in high school foodservices, was investigated. The questionnaires were administered to 379 students and 141 employees in 13 high school, in Busan and then the data evaluated by 5 scales method of Likert were statistically analyzed. The mean scores of the importance and the performance evaluated by students (4.26/3.24) were significantly (p<0.01) lower than those by employees (4.71/4.51). Both the students and the employees percepted that, among sanitary characteristics, cleanliness of meals was most important. The student assessed the performance of withdrawal of plate waste as lowest scores, however the employees assessed student's hygiene as lowest scores, among sanitary characteristics. The gap score of the student (-1.02) between the importance and performance for sanitary factor was higher than that of the employees (-0.02) in high school foodservice. The importance grid of students and employees revealed that the items of tray cleanliness, dining table cleanliness, restaurant cleanliness, and handwashing before serving were high scores to the students, but low scores to the employees. The performance grid of students and employees revealed that the items of tray cleanliness, dining table cleanliness, restaurant cleanliness, the sanitation of treatment process of Plate waste, cleanliness of utensils of platewaste, not touch utensils before serving, handwashing before serving, handwashing before eating and not touch inside of tray were low scores to both the students and the employees. Therefore, it is suggested that the sanitary operations for dining place, treatment process of plate waste and the student's hygiene might have to increase in high school foodservice.

The multiple regression models which have two factors(population and commercial area) have been used to forecast the water demand in the future. But, the coefficient of population had a negative value because proper regional classification wasn't performed, and it is not reasonable because the population must be a positive factor. So, the regional classification was performed by principal component and cluster analysis to solve the problem. 6 regional characters were transformed into 4 principal components, and the areas were divided into two groups according to cluster analysis which had 4 principal components. The new regression models were made by each group, and the problem was solved. And, the future water demands were estimated by three scenarios(Active, moderate, and passive one). The increase of water demand ore $89.034\;m^3/day$ in active plat $49,077\;m^3/day$ in moderate plan, and $19,996\;m^3/day$ in passive plan. The water supply ability as scenarios is enough in water treatment plant, however, 2 reservoirs among 4 reservoirs don't have enough retention time in all scenarios.

As the expansion of the cultural industry expands, various competitive structures are formed and the methodologies for producing commercial success are being discussed. Among them, Hollywood studios use political relationships and apply ideologies that can produce the best interests. Also, they use a structure that can convey this ideology, which is a mythology. The myth has satisfied the public for a ling time. Campbell suggested that strategies come from the myth, and the ideology emerged as a result of what mythology has to do with existing powers. Disney and Dream Works use the mythology and combine their own values into ideology. Disney and Dream Works choose conflicting ideologies in a different growth background. If Disney is recognized as an educational animation by the ruling class, Dream Works are supported by the public for their actions against Disney. Disney has conservative and patriotic personality, Dream Works is more liberal and progressive. Disney's structure came out first, and Dream Works parodied it. So we can compare Disney and Dream Works with similar myths to create a storytelling structure that embodies ideology. As a result, Disney and Dream Works have been choosing the 9 stages the key of Ideology form the 17 stages of the mythology and reduced them to the introduction, growth and completion. In the first units of the introduction, Disney dealt with the subject of social leaders who sacrificed to the ruling class and Dream Works hinted at the overthrow of the ruling class through the irony. If Disney had deployed colored races in the main characters, Dream Works used a variety of races from the main characters to others. In the second units of growth, Disney organized the process of accepting the value of the ruling class, and Dream Works showed the individual values, not the values of society. In the third units completion, Disney showed the main character who live in the world of the ruling class rebuilded, and Dream Works removed the ruling class and went back to the Individual life. Through the structure of Disney and DreamWorks, we learned how to utilize the mythical structures that transform according to ideologies. The right way to organize works will require the strategic approach to storytelling.

The job burnout of the private security guards who provide services through contact with customers can affect the overall the private security industry. So the managers need to make efforts to diagnose and evaluate the job burnout and provide continuous provision for the repatriation effect. However, up to the present, the job burnout measure for the private security guards has not been provided, so the objectivity of the information is questionable. For this reason, in order to establish the goodness of fit of the job burnout scale for private security guards based on the contents of the job burnout scale that was being provided to other service employees, this research aims to provide the scale to provide objective information compared with that of the past by applying the Rasch model of the item response theory. To achieve this purpose, the data on 379 private security guards working for the private security guard companies in the Gyeonggi region were collected, and the data were processed to suit the research purpose using SPSS 18.0 and AMOS 18.0, Winsteps programs. Through these research procedures, the following conclusion was obtained. With regard to the private security guards' measure of job burnout, as a result of factor analysis through the collected data, 4 questions were deleted, and as a result of the analysis of the goodness of the fit based on 18 questions, 4 questions were found to be inappropriate questions that did not satisfy the standard value, and the scope of the difficulty level of the questions from - 98 to 1.30 and the response reaction of a 5-point scale were found to suit the final private security guards' job burnout scale. In other words, the conclusion that it is appropriate to measure the private security guards job burnout scale with 3 factors and 13 questions was obtained. So if private security guards companies collect systematic data using the scale established in this research, and practice refresher training accordingly, they can reduce the private security guards' job burnout.

Purpose: Radio-isotopes (RI) use has been steadily developing due to industrial and technical development in the modern medical society. Particularly, popularization of domestic cyclotrons dramatically enable hospitals to produce and use diagnostic radio-isotopes. Generally, only specific facilities such as hospitals, research institutes, nuclear power plants and universities can use radio-isotopes, they are also responsible for ventilation system. The strength of radioactivity in the air is strongly regulated and controlled by korea atomic energy law in Korea Institue of Nuclear Safety (KINS), so that air radioactivity exposure can lead to environmental pollution surrounding places. In this study, we'd like to find out the investigation and the present condition of the controlled ventilation system in domestic hospitals by an emission standard from KINS, and try to reach an agreement about how to use the ventilation system. Result: Definition of filters, features and structures of pre-filters, hepa-filters, charcol filters, filter exchange procedures and precautions are explained. RI deflation concentration and filter exchange cycle have been presented as a standard prescribed in the rules of KINS. The Radiation Control Management System (RCMS) introduced by Seoul National University Bundang Hospital linking to digital pressure gauge with computer controller in another medical facilities were described in details. Conclusions: The system of medical facilities using RI has been remarkably developing in 21 century. Especially, radiation safety control system has also been grown rapidly into the subdivision, specialization, advanced technology along with international technical improvement. However, As far as current RI ventilation system is concerned, it has nothing better than doing in the past. Preferentially, to reinforce this, more sophisticated system with strict periodic filter exchange and exhaust air control guidance should be introduced by applying brilliant domestic information technology for RCMS and digital gauge method. From personal point of view as a radiation safety manager, I have provide with present problems and improvements. Futhermore, more improved guidance should be conducted.

The phosphorus(P) adsorption capacities of various filter media were investigated in relation to the size and types of fitter media to screen the optimum condition. The objective of this study was to evaluate the constructed wetland longevity by improving P adsorption capacity. The maximum P adsorption capacities of filter media A($4{\sim}10\;mm$), B($2{\sim}4\;mm$) and C($0.1{\sim}2\;mm$) were 8, 10 and 22 mg/kg, respectively, showing those increased as the filter media size decreased. Among the experimental media, the optimum filter media size was $0.1{\sim}2\;mm$. When the filter Medium was supplemented with organic materials which were piled up and decayed in the constructed wetland, the P adsorption capacity was significantly enhanced Under the conditions of optimum fitter media size, the respective Maximum P adsorption capacities of filter media C when supplemented with Ca, Mg, Al and Fe were higher than that of filter media C. However the addition of Ca, Mg, Al and Fe to constructed wetland were not recommended because of the possibility of their secondary pollution. The maximum P adsorption capacity of filter media C was 22 mg/kg, but this was increased to 36 mg/kg when filter media C was supplemented with 2% oyster shell.

The purpose of this study was to investigate the eating behavior, food preference and nutrition knowledge according to the body style of male college students. The subjects were 219 male students enrolled in University, Taegu. The data was collected by using a survey questionnaire and an anthropometric measurement. The results were summarized as follows: The mean height, weight and BMI of subjects were $173.8{\pm}8.7cm,\;65.8{\pm}7.9Kg,\;and\;21.9{\pm}2.4$, respectively. The subjects were divided into three groups according to the BMI: underweight group(<20); normal group(20-25); and overweight group(>25). One third of the subjects preferred to gain weight(33.8%); 47 subjects preferred to lose weight(21.5%); and the rest of the subjects satisfied their physique(44.7%). Most of subjects considered 'supper' as the most important meal during a day. Among the food items, the most frequently and evenly ingested item by subjects was 'Kimchi' : 'Ham and sausage' was the least preferred food among subjects. There was no significant difference in preference among three groups and almost half of the subjects had irregular meal time because of busy schedule. The preference for meat showed high score among underweight group; on the other hand, the preference for fruits and vegetables showed high score among overweight group. Usually subjects gained nutrition knowledge through media including newspaper, magazine and TV. There was no significant difference of the nutrition knowledge score among three groups. Based on these results, nutrition education program for the college student should be arranged in the classes.
