All of the subjects of the investigation (n=141) were schools that have food services under direct management. The number of students who get food services at the schools were $1,001{\sim}1,500$ students with 46.8% investigation. In school food services, fried foods were highly preferred and the biggest merits of fried foods were (in order of highest importance) 'improvement of food services satisfaction'> 'source of calories supply'> 'easiness of cooking process'. Service frequency of fried food were in the order of 'twice a week'> 'three times a week'> 'once a week', and for the factors to decide service frequency of fried food, 'preference leaning on fried food', and 'excessive fat intake' were the most considered. The most considered factors in the case of choosing fried food were 'preference' and 'calories and nutritional value'. For the cautious steps during the frying process, 'keeping after frying' was picked the most, and the reasons were 'lack of containers to keep in appropriate temperature and quality' and 'time consuming'. For preference and service frequency of ingredients in fried foods, 'chicken' and 'pork' were very high. As the result, it was analyzed that preference by ingredients matched service in school lunches by using a ranking test. Total cooking and processing time of fried foods required in school lunches were approximately $237{\pm}99$ minutes ${\sim}291{\pm}141$ minutes which showed total required time was about same no matter what ingredients were used. As the result of comparing and analyzing the processes, vegetables took less thawing and frying time, but the processing time for vegetables was more complicated since handling time before frying was longer compared to meat. In the important management process by the main groups of fried foods, the frying process was the most cautious cooking process in the category of meat or fish and shellfish used as ingredients. In addition, if vegetables were used as ingredients, storing it after frying was the process that needed the most care.

Aims: The present study investigated the relationship between condylar resorption and craniofacial skeleton types(especially vertical relationships), the differences of craniofacial skeleton types between with open bite group and without open bite group, and the associations of anterior disc dislocation with or without reduction to condylar resorption with MRI. Patients selection and methods: Clinical examination, magnetic resonance imaging (MRI), panorama, lateral transcranial and lateral cephalometric radiographs in 34 patients with condylar resorption were used to investigate this relationship. Results and Conclusions: Patients with the following specific facial morphologic characteristics appear to be most susceptible to condylar resorption: (1) females were predominant, (2) patients' age ranged from 12 to 50 years old with a strong predominance for 2nd and 3rd decades, (3) patients had high mandibular plane angle and high gonial angle, (4) patients had decreased vertical height of the ramus, (5) patients had generally significant antegonial notch, (6) patients had predominance of Class I occlusal relationship with or without open bite but mandible was retruded as mean ANB 5.54 degrees, (7) condylar resorption rarely occurs in lower mandibular plane angle facial types, (8) although no statistically significant difference was found, the open bite group had a tendency more hyperdivergent skeletal pattern than the non open bite group, and (9) imaging demonstrates from small resorbing condyles to idiopathic condylar resorption and TMJ articular disc dislocations. Thus, morphologic features of patients with vertical discrepancies may represent a risk factor for the development of condylar resorption.

The major purpose of this study is to examine how the perfectionism of dance majors affect self-efficacy and performance satisfaction. The sampling of this study was done in 2009, by using purposive sampling method with the subjects who are currently the students of an arts high school and dance majors of a college in Daejeon and Chungcheongnam-do. Specifically, by dividing the district in Chungnam and Daejeon, one arts high school and one college were selected from each district, and 75 dance majors from 4 schools respectively, total 300 students were examined for the study. Among these 300 students, the number of students' questionnaires used in the final analysis is 274, excluding the questionnaires containing inadequate answers. The adequacy of the questionnaire was verified by factor analysis, and the reliability of the questionnaire by reliability analysis. In the matter of reliability, Cronbach's ${\alpha}$ turned up to be over .602. In this study, factor analysis, reliability analysis, regression analysis, and course analysis were done by using SPSS16.0. With the above research method and results, I could come to a conclusion as following. Above all, perfectionism affects the subordinate variable of self-efficacy, the self-control efficacy. That is, with the higher self-oriented perfectionism and the other-oriented perfectionism, self-efficacy increases more as well. Secondly, perfectionism affects performance satisfaction. In other words, the higher self-oriented perfectionism, the higher performance satisfaction. Thirdly, self-efficacy affects performance satisfaction. That is, higher self-control efficacy makes the performance satisfaction higher. Lastly, perfectionism affects self-efficacy and performance satisfaction either directly or indirectly. Now it is obvious that self-efficacy is the variable that intermediate performance satisfaction.

The purposes of this study were to investigate supporting status and subsidy for school food service and to analyze the perception of school food service officials at the educational board on using rice bread to the school food service menu. The questionnaire was developed by content analysis, situation analysis, in-depth interview and checked by the school food service officials at the educational board. The questionnaires were responded by 33 officials (respondent rate: 86.8%) during September 1 to October 26 in 2007. The major findings of this study were as follows: First, most of the respondents were women (93.9%), and worked an average of 104.36 months at school-related work. The metropolitan & provincial office of education had prevalently jurisdiction over 272.3 rural and self-operation type of elementary schools, 115.50 rural and self-operation type of middle schools and 73.0 rural and self-operation type of high schools. In the case of the district office of education, 23.3 urban and self-operation type of elementary schools, 11.6 urban and self-operation type of middle schools and 5.3 urban and contracted type of high schools were averagely managed. Second, all the respondents supported meal cost for low-income group and 50.5% provided reimbursement for organic environmental agricultural products. The highest subsidy was 16.8 billion won as meal cost for low-income group in metropolitan & provincial office and 1,050 million won as labor cost in district office. Third, the experience of performing policies for using rice was relatively lower than perception of rice bread application to school food service menu. Fourth, the advantages of using rice bread were acceleration of consuming rice (32.0%), excellence of nutrition (24.0%) and promotion of healthy image (22.7%). On the other hand, the difficulties of using rice bread were lack of facilities (72.7%), higher cost compared to wheat bread (54.5%), limitation of menu application and cooking method (15.7% each). Fifth, the opinion of utilizing rice and that of applying rice bread were significantly correlated (p<0.001). Desirability and willingness were correlated with reality for applying rice bread to the school food service menu (p<0.001). Also, comparative analysis between divided groups by perception of utilizing rice showed that willingness and experience were significantly different.

In this study, the actual condition in operating Information Disclosure System and University Information Disclosure was investigated and analyzed for 413 universities which had their own homepages out of the total 414 universities, which were the targets of university information disclosure in 2008. To activate Information Disclosure System of the academic library, how to use Korea Library Statistics Items and National Libraries Operation Assessment Index as the standard of information disclosure, and how to use a national library statistics system effectively were suggested. In addition, to make University Information Disclosure efficient, the amendments about the status of books holdings and library budget were respectively suggested so that the items and contents of disclosure about the status of library support might be disclosed by focusing on the security of finance and the improvement of the academic library. In order to enhance the interest of universities and in society and policy, it is necessary for the academic library to make use of Information Disclosure System and University Information Disclosure as a major means.

The results of a survey on 6,192 elementary schools across the country in April 2019 are as follows : First, there was a correlation between the number of students and the number of classes. Second, 2,788 schools (45.0%) were small schools, 1,931 schools (31.2%) were suitably sized schools, and 1,473 schools (23.8%) were large schools among the 6,192 elementary schools surveyed. Third, there was a significant difference in the proportion of small schools, suitably sized schools, and large schools by province. Among the 8 metropolitan cities, Seoul had the lowest percentage of small schools at 9.8%, followed by Incheon at 18.0%. Among the 9 provinces, Gyeonggi Province had the lowest rate at 26.8%, while Jeollanam-do had the highest rate at 87.2%. This means that adopting the same standard for abolition of small schools throughout different provinces can cause serious problems. Therefore, it is necessary to reflect the educational conditions of each province.

The purpose of this study is to investigate the stability of counterclockwise rotation of mandible by sagittal split ramus osteotomy to correct the skeletal Class III malocclusion with anterior open bite. Twenty five skeletal Class III open bite patients(mean age 20.6 years) who were treated by the sagittal split ramus osteotonues with rigid fixation were examined in this study. Cephalometric radiographs were taken for each Patients Preoperative(T1), ewly Postoperative(T2), and late postoperative Period(T3). Mean postoperative period was 8.0 months. Cephalometric analysis was done and data from T1, T2, and T3 were analyzed statistically by Paired t-test and Pearson correlation analysis. The following results were obtained. 1. Mandibular plane angle decreased $2.9^{\circ}$ and mandibular occlusal plane angle related to SN Plane decreased $2.7^{\circ}$ after orthognathic surgery(T2). At 6 months after orthognathic surgery(T3), mandibular plane angle increased $1.0^{\circ}$, but mandibular occlusal plane angle did not changed. 2. The amount of horizontal relapse long time after orthognathic surgery(T3) was 1.6 mm at B point and it was $22\%$ of the total posterior movements. There was no vertical relapse in the anterior facial height. 3. The related factor with horizontal relapse at late postoperative period was mandibular plane angle(p<0.01). The related factors with decreasing posterior facial height were amount of mandibular setback(p<0.01), increasing of mandibular ramus height(p<0.01), and decrease of the mandibular plane angle during operation(p<0.01). 4. There was no relationship between the amount of changes in mandibular occlusal plan angle during operation and the amount of relapse after surgery.
