The measurement of gross beta activity and the concentration of ^90Sr in the vegetables such as Brassica Campestris, Raphanus Sativus and Lactuca Sativa grown in Daejeon area was carried out during the period of April through August 1983. The observed levels of gross beta activity and the concentration of ^90Sr in the leaves of the vegetables were, on average, 189.2±51.8pCi/g-ash(2372±827pCi/㎏-fresh) and 44.4±11.5 ^90Sr pCi/g-Ca(2.5±0.5 ^90Sr pCi/g-ash or 31.6±8.6 ^90Sr pCi/㎏-fresh), respectively, while the mean level of the gross beta activity in roots was 158.6±19.4pCi/g-ash(2121±899pCi/㎏-fresh). On the basis of the ICRP recommendations, an estimative evaluation was made for the concentration of ^90Sr in the vegetables, and it was turned out to be far below the permissible level. An attempt was also made to look for any existing difference in the gross beta activities of the vegetables grown in vinyl house and in open field, taking seasonal variation of airborne radioactivity into account for normalizing the activity deposited during the course of discrepant farming period.

Edible flower means a flower that is good to eat is subject to either cooking or appetizing. In general, people eat edible flower as raw so that the loss of vitamin and inorganic are minimal. Edible flower is usually utilized as salad material or aromatic, decoration for jelly or cake and solid stuff in soup. Thus, decorating food by edible flower improves flavor, fragrance and appetite. Edible flower serves various purposes both east and west. In Korea, Edible flower is mainly subject to soup, cooked potherbs, frying, tea stuff, brewing and etc, whereas in Japan, its various usage covers cooked potherbs, pickle, sliced raw fish, frying, salad, jelly and decoration. On the other hand, Edible flower is used as numerous salad and tea stuff, condiment, roasting, meat, sweets and desserts in Western Hemisphere.

There are 241 kindergartens in public schools and 18 Sae Ma Ul co-operative nursery schools at no cost to the parents In Choong Nam province at present (Dec. 1981). There are 98 Kindergartens in public schools and 14 Sae Ma Ul co-operative nursery schools In Choong Buk Province. The purpose of our study is 1. to ascertain the Status of Kindergartens and Sae Ma Ul co-operative nursery schools in Choong Nam and Choong Buk Province. 2. to study the administrative problems of the kindergartens through questionnaires and discussions with kindergarten directors, teachers and parents. 3. to study the back-ground of the process and development of Korea Kindergartens. 4. to make recommendations to the government, Ministry of Education, and to the Educational Association in order to improve early childhood education. The results and our recommendations are as follows: 1. Efficient kindergarten administration 1) Kindergarten children need private class rooms. 2) Substitute teachers need to be trained ahead of time. 3) Most teachers are teaching primary children in the morning and kindergarten children in the afternoon. Because of the physical and emotional demands of the job a person over 50 years old would not be suitable. 4) It would be advisable for teachers to reach only one class, instead of the two, as the job is very strenuous. 5) Provide teachers with the opportunity for advance study through night college or college study during vacations to improve the teachers' qualification. 6) The directors, supervisors, and teachers need to be trained through reeducation and seminars to understand kindergarten education. 7) At the present, there are three different competent authorities for the early childhood education institutions (kindergartens under the Ministry of education, Children's home under the Ministry of Health and Social Affairs, and Sae Ma Ul co-operative nursery schools under the Ministry of Home Affairs) . It is hoped that the competent authorities can be unified. 8) There must be a government school inspector who hat majored in earth childhood education working at the educational Association in each city, county and province. 2. Kindergarten curriculum 1) We need to develop kindergarten curriculum which is suitable for the individual kindergarten. This can be done through research studies by a model kindergarten or early childhood education department at the college level. 2) To provide sample kindergarten materials once or twice a year at an exhibition sponsored by the government. New teaching materials and equipment would be introduced and creative ideas exchanged by the participants. 3. Teaching materials, equipment, and facilities 1) More than 2/3's of the kindergartens and Sae Ma Ul co-operative nursery schools are sub standard in teaching materials, equipment, and facilities. 2) More government subsidies are needed through the new Education tax to bring teaching materials, equipment and facilities up to standard and provide quality education for young children. 3) If government subsidies are not enough to provide quality education, the parents gust be charged a small fee according to the situation of the district. We need to solves many problems through continuing research studies and in co-operation with government, teachers and parents to provide the best early childhood education possible for well-rounded children in Korea.

This study was carried out to investigate the current nutritional problems owing to the increased consumption of westernized food in Korea and also was conducted to compare the nutritional characteristics of Korean traditional meal with those of the Western diet in similar serving size. The results obtained from nutritional evaluation are as follows: 1. The percentage of calories represented by carbohydrate: lipid: protein was 65:15:20 respectively for Korean traditional meal (Table setting of 3 Chop) therefore these ratios meet the dietary recommended allowances for Koreans. 2. Nutrient values of Korean traditional 3-Chop were shown to be better balanced than those of Western diet when the nutrients of the two types of diet were estimated by similar serving sizes and calories. 3. Compared to the Korean traditional meal, most fast foods were nutritionally imbalanced especially in that most of them showed higher amounts of fats. These results show that Korean traditional meals supply ideal nutrient intakes in contrasts to the westernized diet, therefore much work remains in developing a variety of menus and standard recipes for Korean traditional meals according to the changes in diet trends as well as emphasing the importance of Korean traditional meals as part of an ideal, well-banlanced diet.

Liquid phase oxidation of p-xylene using molecular oxygen has been carried out on the Co/Mn/Br-based catalyst system in acetic acid as a solvent. Process parameters(total pressure, partial pressure of oxygen and temperature) and kinetics of the reaction were studied as a basic study in the viewpoint for the development of new catalyst system and process. The total pressure above 20atm and the partial pressure of oxygen above 5atm were required to keep the reactant in the liquid phase and to overcome the mass transfer limitation of oxygen. The oxidation rate conversion were increased with increasing reaction temperature to the 100∼190℃ range. For a given initial concentration of p-xylene, the oxidation rate and the apparent activation energy were found to be of first-order and 4.24 ㎉/㏖, respectively. The effect of the third components added to the Co/Mn/Br catalyst was also studied. It was found that Ni is only a good additive that can promote the catalyst performance.

옥외 라돈이 호흡기관에 주는 선량을 측정·평가할 목적으로 CR-39 비적검출기를 내장한 라돈컵을 사용하여 대기중 라돈농도를 측정하였다. 직접형 검출기 및 개방 컵과 필터 컵의 구조를 갖는 CR-39비적검출기에 대한 라돈검출인자는 공기중의 농도가 잘 알려진 표준라돈 조사시설에서 이들 검출기와 라돈컵을 일정기간 조사하여 결정하였다. CR-39를 70°c, 30% NaOH용액으로 220분간 화학부식하였을 때 직접형 거출기와 개방 컵, 필터 컵에 대한 라돈검출인자는 각각 0.273, 0.0813, 0.0371tr mm-2/37 Bqm-3·d)였다. 또한 1988년 5월에서 1989년 3월까지 대전(충남대학교)에서 측정한 대기중의 라돈농도는 개방 컵에 의한 결과는 27.4 - 135.8Bq/m3(0.74 - 3.67 pCi/l)로서 연평균 73.3 Bq/m3(1.98 pCi/l)이었으며, 필터 컵에 의한 결과는 16.7 - 143.9 Bq/m3(0.45 - 3.89 pCi/l)로 연평균 68.5 Bq/m3(1.85 pCi/)이었다. 측정한 옥외 대기중이 라돈농도와 부위별 폐선량모형으로부터 산출한 ICRP표준인의 호흡기관에 대한 실효 선량당량률은 약 520 nSv/h로 평가되었다. A study for the assessment of dose given by outdoor radon to respiratory system has been carried out by making use of radon-cups containing CR-39 plastic track detectors. Detection efficiencies were determined by irradiation of the radon-cups in a standard radon chamber of known concentration. Thus determined detection factors of CR-39 plastic track detector in bare, open cup and filtered cup geometry are found to be 0.273, 0.0813 and 0.0371 trmm-2/(37 Bqm-3 d), respectively, which are chemically etched in 30% NaOH solution of 70℃ for 220 minutes. The outdoor radon concentrations measured at Taejeon (Chungnam National University) from May 1988 to March 1989 are in the range of 27.4 - 135.8 Bq/m3 (0.74 - 3.67pCi/l) by open cup and 16.7 - 143.9 Bq/m3 (0.45 - 3.89pCi/l) by filtered cup, which yield overall annual average value of outdoor radon concentration of 70.8 Bq/m3 (1.91 pCi/l). Corresponding effective dose equivalent rate to respiratory system of ICRP standard man is assessed to be 520nSv/h.
