To evaluate the results of nutritional education in junior college, the content of lunch box of junior college students were surveyed. Among 749 students in Gunsan Fisheries Junior College, 325 men who had carried a lunch box were selected as subject. All the nutrients except vitamin D given in Recommended Daily Dietary Allowances for Korean people, and foods in lunch box were also considered as a food groups. To see how many students had interests about their own nutrition, people who packed lunch box were also checked. The results obtained from this survey were: 1. All the nutrients except calcium and iron of lunch box were low when compared with Recommended Daily Dietary Allowances of Korean people. 2. Vitamin A was approximately similar to the Recommended Daily Dietary Allowances for Korean people. 3. Over 50% of calorie, protein and niacin were provided by main food, although other nutrients were principally from supplemental foods. 4. Supplemental foods were few in kinds and chiefly salty foods such as preserved and processed foods in the lunch box. 5. There may be a fault in nutritional education in junior college because there were few students who had an interest in their own nutrition.

Authors tested the grid functions with various thickness of acryl phantom, radiation field size and diameter of shielding lead. The results are as followed: 1. The characteristic values of grid are affected by phantom thickness, but free from radiation field size in the diagnostic useful range. 2. The quantity of scattered radiation was decreased according to the diameter of shielding lead under 20mm, and then the diameter the smaller the better, in accordance with proposed KS standard. 3. The quantity of primary radiation was increased a little at the 80mm diameter radiation field size, but did not have much differences. Therefore, it was thought that it is needed to limit beam size in case of absolute values in accordance with any standards, but it has no matter to use 100 mm diameter in case of relative values just to campare with.

We have conducted on experiment with a purpose to evaluate the performance of grids being used at hospitals in Seoul and adjacent cities of Seoul. The results are as follows; Reality of the grids use 1. The focused grids were 105 and the parallel grids were 6 among 111 grids subject to experimenting. 2. The grid interspace material was aluminium of 94 and the remains were wood and bakelite. 3. The umber of Korean products from five companies was 33 and the one of the foreign products was 34 from companies. The physical properties have been examined by the notice of Department of Health and Social Affairs. 4. The intensity of secondary radiation was the highest in 5 : 1 grid ratio. 5. The Bucky factor increased with the increase of grid ratio. The selectivity, the grid improvement factor of grids also increased with increase of the grid ratio. However, with 6 : 1 grid ratio those factors were decreased exceptionally. In measurement of grid density with screen determiners and the beam alignment. 6. In evaluation the results were satifisfied within, 20%. 7. The value of the scale and the value of measurement were within the range of standard deviation, but the value of 103 lines were outranged from the standard deviation with all grid ratio except of 6 : 1 grid ratio.

X-ray grid is the most important means to reduce the scattered ray from patients, but alternative way is air gap technique that is another name of Groedel technique. This technique is mainly used in chest radiography. Authors performed an experimental study on the air gap technique for chest radiography and obtained the results as follows; 1. In using the high voltage air technique, scattered ray could be reduced effectively, while the percentage of scattered ray was slightly increased than conventional grid technique. 2. In film contrast, 30cm air gap technique was inferior to 12:1 grid technique and contrast improvement was increased when the object was thicker and higher voltage was used. 3. The patient exposure dose was reduced about $25{\sim}45%$ compared with conventional grid technique by air gap technique used.

본 연구의 목적은 4년제 대학도서관에 비해 상대적으로 열악한 환경에 처해 있는 전문대학도서관의 현황과 문제점에 대해 분석하고 이에 대한 개선방안을 제시하는데 있다. 전문대학의 개념과 목적에 대해 알아보고 전문대학도서관의 각종 통계를 통해 외부적인 환경에 대한문제점을 제시하였다. 개선방안을 마련하기 위해 대구지역 소재 전문대학도서관의 장서 수를 기준으로 사례도서관을 선정하였고, 해당 도서관의 웹사이트를 분석하여 전문대학에 맞는 정보서비스 사례를 수집하고 해당 전문대학도서관 사서에 대해 심층인터뷰를 실시하였다.

The purpose of this study was to examine the developmental changes about self-perception from childhood to adult period. The subjects were 365 of 5th graders in elementary school, the 2nd graders in junior and senior high school, sophomore in college, and adults. The instruments used for this study were Harter's Self-Perception Profile for the children, adolescences, college students, and adults. The results were as follows. 1. From elementary school to junior high school, the score of scholastic, athletic, physical appearance, behavioral conduct, and global self-worth were decreased. At the developmental perspective, the junior high school students were highly anxious for self-perception. 2. Physical appearance were the best predictor of the global self-worth for all developmental stages. 3. Physical appearance, behavioral conduct predicted more about the global self-worth than any other factors for elementary and junior high school students. And for junior high school students, social acceptance and friendship also predicted about the global self-worth. Scholastic competence showed higher correlation with global self-worth for the senior high school and college students than elementary and junior high school students. 4. For college students, males had higer scores than females on ability-oriented but also relationship-oriented subscales. But the adults showed no differences in nurturance, household management, job competence depending on sex.
