To propose a useful modelling method for an actual muffler, the noise attenuation effects of muffler was investigated according to the flow condition and the hole shape of tubes. In this work, the finite element method was used to calculate the transmission loss of muffler, The noise attenuation characteristics of four different types of muffler in the hole shape of tubes were compared mutually to find a more simple equivalent model. Analytical results showed that the overall value of transmission loss increases and the peaks of transmission loss curve shift to the low frequency with mean flow for the given muffler, Also the noise attenuation characteristics of the equivalent model having the split holes is almost the same as those of the actual muffler having many circular holes.

Purpose: This study was carried out for the purpose of obtaining basic data necessary for developing the future oral health promotion program of the elderly by surveying the actual condition of managing dental prosthesis in the elderly. Methods: It collected materials targeting 346 elderly brackets in over 65 years old who dwell in Seoul and Gyeonggi-do Province for about 10 months from September 2010 to June 2011, analyzed 312 copies except 34 copies, which are inappropriate for data processing due to being insufficient in response among these things, and obtained the following results. Results: In the actual condition of missing tooth, a case of missing tooth was indicated to be 78.8%. In case of missing tooth, the number of missing teeth was indicated to be 75.6% for under 5 pieces and 19.1% for over 21 pieces. In the actual condition of managing prosthesis, a case with dental prosthesis treatment was indicated to be 77.6%. A kind of prosthesis was indicated to be the highest in fixed partial dentures with 36.5%. In a method of rinsing dentures, 47.7% of the elderly responded as saying of washing it out with water. The appearance of removing dentures at night was indicated to be the highest in doing so with 63.1%. Satisfaction with prosthesis of being mounted now was indicated to be moderate with 50.4%. As for the appearance of having experience of education on how to manage prosthesis, it was indicated to be high with 50.4% in having none. In a kind of prosthesis depending on averagely monthly income, the ratio of total dentures was high when averagely monthly income is low. On the other hand, a case with high income was indicated to have high ratio in implants. The satisfaction with prosthesis was low when averagely monthly income is low. Also, in the experience of education on how to manage prosthesis, the ratio of responses as saying of having no experience of education on how to manage prosthesis was indicated to be high when averagely monthly income is low. Conclusion: Examining the above results, a developmental plan is considered to be necessary such as developing continuous and systematic oral health promotion program for managing elderly people's managing dental prothesis.

The purpose of this study is to emboss the importance of safety education by recognizing the instructor's thoughts on safety and the prevention of safety accidents of early-childhood through the examination, analysis of the education site of safety at early-childhood education facilities. The subject of this were 120 early-childhood teachers in the Jeonbuk areas. The data were collected using questionaries and analyzed by the statistical methods of frequencies. ANOVA with SPSS pc program. The research questions were as follows; 1. What is the understanding of early-childhood teachers on safety recognition? 2. Is there a difference in the understanding of the teacher on safety and the management of the education curriculum on safety education that is being taught at early-childhood education facilities? The main results and solutions of this study were as follows: 1. In order for early-childhood teachers to teach safety education in early-childhood education facilities, they must join a safety mutual aid association or join an insurance policy to furnish an appropriate compensation system. Also, safety education must be systematically taught at a $social{\cdot}national$ level so that teachers and young children can have an understanding on safety under the support and concern of early-childhood education facilities and administration authorities. 2. Results on the comparison of the understanding of safety education and management of actual education of teachers on the actual conditions of the education curriculum of safety education show that although teachers are aware of most items of safety education but the actual education was not being taught. This means that although the teachers are aware of the importance of safety education, the actual education is not being taught.

The author has developed the computer program in order to calculate the optimum alignment condition of marine propulsion shafting by linear programming method. The input of program was calculated by the matrix method of three-moment. He compared the calculated values with the experimental values measured by the strain gage on the model shaft, and the values of calculation on actual propulsion shafting with those of Det norske Veritas. The computer program of optimum alignment has been applied to the actual shaft. The results obtained are as follows: 1. To obtain the reaction of supporting points in the straight line necessary to the optimum alignment and the reaction influence number, after the computer program had been developed and then adapted, the result of experimental values and calculated values agreed with each other and the values of the actual shaft were also approximately similar to the values of other program. 2. In this paper, the measuring method on model shaft by strain gage can be effectively used at the time of adjusting alignment condition of actual shaft. 3. The supporting bearing should be considerably readjusted to the vertical direction in order to satisfy some limited condition.

This study aims for examines the actual physical symptom and stress in caregivers of patients with cerebrovascular disease. The data were collected by a survey conducted from August to September, 1997 which included 65 caregivers of cerebrovascular disease patients in 4 hospitals located in Seoul. The caregiver's stress was measured by Choi (1992)'s instrument and the actual physical symptoms were investigated. The data were analyzed using ANOVA, Scheffe test, Pearson correlation coefficient and stepwise multiple regression. The results were as follows : 1. The mean number of caregiver's physical symptom was 3.5. There were significantly higher number of physical symptom in women, those of who have a religious affiliation, those of who perceive their own health status perceived as bad, and those of who perceived their patients disease condition as serious than in their counterparts. Also, the number of caregiver's physical symptom was significantly higher in caregivers whose patients have a paralysis sypmtom and the disease onset as accident than in caregivers whose patients have no paralysis symptom and the disease onset as spontaneous. 2. The average of caregiver's stress was 57.9. The caregiver's stress was the highest in between the ages of 50 and 59. There were also significantly higher level of stress in women, those of who perceived the disease condition of their patients as serious than in their counterparts. 3. The most common caregiver's physical symptom was fatigue(87.7%). This was followed by insomnia(58.5%) and muscle pain(47.7%). 4. Caregiver's physical sypmtom was positively correlated with caregiver's stress and negatively correlated with patient's activity of daily life. 5. The most important vairable affecting the caregiver's physical symtom was patient's activity of daily life which accounted for 12.7% of the total variance in stepwise multiple regression analysis. The most important vairable affecting the caregiver's stress was the patient disease condition perceived by the caregiver that accounted for 12.1% of the total variance.

The purpose of this study is to investigate the potential water condition of Honam region according to water budget analysis. For this purpose, the eight regions (Suncheon, Gwangju, Jhangheung, Damyang, Mokpo, Yosu, Huksando, Namwon) are selected as study area. The result is as follows. (1) The water surplus indicating the potential water condition is ordered as Yosu, Sunchon, Changhung, Namwon, Damyang, Huksando, Kwangju, Mokpo. So the potential water condition of Kwangju and Mokpo is worst among study regions. (2) The high water surplus region is corresponded to high precipitation and low actual evapotranspiration legions. (3) The potential water condition is to agree with several facts about the water resource condition of Honam region. For example, large scale dam of Honam region has been constructed for Kwangju and Mokpo city. This fact indicates that the potential water condition calculated by water budget analysis is corresponded to actual water resource condition. (4) Consequently, the water budget analysis is effective method for investigating the actual water condition and establishing the water resource management of specific regions.
