The head louse infestation had been no problem since 1960s in Korea. However, the present study revealed high infestation rate among the primary school children in Seosan-gun, Chungnam Province in July 1983. The cases of louse positive were determined by identifying the adult worms and/or their llits on scalp and hairs. The overall louse positive rate among 615 children examined was 73.5%. The rate was higher in girls (78.8%) than in boys (67.6%) and was highest in 3rd-4th school grades. It was observed that the more the number of family members the higher the infestation rate of children. The positive children were treated with 20% benzyl benzoate solution after the teat for louscidal effect in petri dish. However, establishment of intensive control measure is needed to prevent further infestation.

This study was performed to investigate the food preference trends of the children according to age increase and change of the times. The subjects were 1,450 children who are fifth grade of primary school and 2,000 juveniles who are senior high school in 1993. This survey data were compared with the Food preference study of the primary school aged children in 1987.' The results of this study can be summarized as follows 1. State of the general taste The subject had a high preferences to bulgogi(roast beef), panbroiled cuttlefish, steamed egg, fried sausage and donuts among the all sorts of 165 principal and subsidiary foods. But, fried beef liver, pancake, sweet potato with syrup, spinach soup and boiled rice with red bean didn't suit for their taste. Compared with survey data done in 1987, in present study significantly increased preferences to steamed food, pan frying and parboiled vegetables were shown. Particularly, food preference was changed with the cooking methods rather than materials. 2. Differences of the preference according to change of the times In present study, except the rice cakes preferences to all sorts of foods were improved and markedly increased preferences to steamed food, parboiled vegetables and mixed with seasonings were observed. Compared with 87's study deviation of the preference to cooking materials was decreased considerably. Preferences to salty tasted foods as like as stew and salted food were low no better than before. 3. Changes of preference according to age increase Among the principal foods, increased preferences to boiled rice and cereals were shown but to one-dish meal, bread and rice cake were decreased. Among the subsidiary foods, significantly decreased preference to frying was observed. Irrespectively of the cooking methods, preferences to fish and vegetables were improved. And in the frying and panbroiled foods, deviation of preferences to cooking materials were considerable, which means the fixation of food behavior.

The purpose of this study was to seek desirable direction of science teaching and to present meaningful ideas for implementing the science curriculum and teaching materials by measuring the degree of the students' understandings on science and comparing it with those of American students. The researcher comprised 790 primary and middle school students for the study and administered them questionnaires developed by Trowbridge, Bybee, and Sund. The questionnaires were analyzed along with three categories such as science method, science theory, and the achievement of scientists. The researcher used t-test and ANOVA in order to compare the difference of their understandings in accordance with grades and gender, and later compared Korean students' understandings with those of similar aged American students administered by the National Assessment of Educational Progress (NAEP) The research loathed to the overall conclusions as follows; Both primary and middle school students' understandings on science revealed positive and appeared no significant difference in gender. And it is thought that science education was being carried out hopefully to enhancing Korean students' scientific literacy, therefore, science teaching like what is implemented to the classrooms currently should be kept on in future. On the other hand, it is necessary to change primary school children's understandings on attitude and value of scientists while to change middle school students' understandings on scientific processes by experiment. Also primary school children need to understand that scientists are willing to change their ideas when new information becomes known.

Primary polydipsia (PP) is marked by an increase in thirst, and most often presents in patients with psychiatric illnesses. Although uncommon in children, we experienced cases of PP in a 15-month-old boy and a 5-year-old girl. Both were admitted to the hospital with symptoms of polydipsia and polyuria that appeared 1-3 months before admission. Brain magnetic resonance imaging in both patients was normal. A water restriction test was performed after hospitalization and showed normal results. The symptoms improved after the parents were instructed to implement water-intake restriction for 2 weeks. Our report provides useful information for the treatment of PP in children.

본 연구는 정규교과과정으로 활용될 수 있도록 개발된 사회인지학습이론 기반 흡연예방 교육프로그램의 효과를 측정하고자 수행되었다. 프로그램 적용대상은 D 광역시 소재 4개 초등학교의 1학년, 3학년, 5학년 학생으로 실험군과 대조군이 1학년은 54명과 50명, 3학년은 57명과 54명, 5학년은 101명과 99명이었다. 프로그램 실시는 1학년은 2시수, 3학년은 4시수, 5학년은 6시수가 2013년 11월 1일부터 12월 19일까지 이루어졌다. 프로그램의 효과측정을 위해 흡연 지식 및 태도, 자아개념 도구를 사용하였으며, 수집자료의 분석에는 Chi-square test와 t-test를 사용하였다. 연구결과 프로그램 실시 전후 흡연지식에서는 모든 학년에서 통계적으로 유의한 차이가 있었으나 흡연태도와 자아개념에서는 차이가 없었다. 초등학생 대항 흡연예방 프로그램은 정규교과과정에 연계되어 단계별로 적용되어야 하며 단기 효과보다는 장기 효과를 목표로 하여야 할 것이다.
