Through the questionaire inquiry from April 1st to 10th, 1974 with 393 students in Woonho, Saekwang junior and senior highschool and Daisung, Ilshin girls' junior and senior highschool in Chungju, Choong Cheong Buk Do, I surveyed the general circumstances of students and their unbalanced diet on total 199 foods and causes of the unbalanced diet and regard the 21 boys and 29 girls who don't like to eat more than 30 foods from the given 47 protein-foods which are needed by students who are now in the stage of growth. This study is concerned with their circumstances and the causes of their ill habit of eating. 1) As to their distribution of age, 14 and 18 year old boys were six (28.5%), 11 and 13 year old girls were eleven (38.1%). In the survey on their height, 6 boys (28.5) were from 146 cm to 150 cm and 11 girls (38.1%) were from 146 cm to 150 cm. On the weight, 7 boys were from 36 kg to 40 kg(33.7%), 10 girls were from 36 kg to 40 kg (34.0%). We can see that ill habiters of eating were more weaker than other students from this data. 2) In the survey of educational level of their housewive it was found that number of graduates of the primary school is thirty (60.0%). So we can derive the fact that they don't make any variety in their daily table for their family. 3) As to their living standard, 19 boys (90.4%) and 27 girls (93.3%) belong to the middle class, low and high class were a little. This indicates the general living standard if Korea, because in common sence we regard the riches are the more ill habiters of eating. 4) 8 boys (36.8%) and 8 girls (26.8%) were the first children in their homes. This indicates the fact that housewive happen to make the first child as the ill habiter of eating because their lack of experience to give various food for their children. As to the survey on their infant nutriments, 41 students (80.2%) were fed by mother's milk. 5) Upon the causes of the unbalanced diet on a certain food, 34 boys (82.7%) and 45 girls (64.6%) were because of appearing to that food, 10 boys (40.8%) and 18 girls (61.5%) were because of the characteristic fragrance, 11 boys (52.4%) and 17 girls (58.1%) were because they have never eated that food till now, 34 boys (19.3%) and 5 girls (17.0%) were because of the bad appearance of the food. So housewive should study various ways of cooking daily meals at home and try to give their children who are in the stage of growth to be able to eat wider kinds of foods for the improvement of health.

In this study, we investigated the difference in the affective characteristics between science-gifted students and general students through the positive experiences about science (PES) index. We also explored ways to apply the characteristics of gifted classes suggeseted by the teachers of this study, which had a positive effect on science-gifted students, to general science classes. For this study, a PES survey was carried on middle school science-gifted students enrolled in the gifted education center in the central region and general middle school students in the same area who had no experience in gifted education. Based on the survey result, we conducted in-depth interviews with teachers, having teaching experience with both science-gifted and general students. The results revealed that science-gifted students showed a significantly higher PES index than general students in all five areas of PES. The area with the largest difference between the two groups was science-related self-concept and the smallest was science academic emotion. Teachers suggested ways to apply the characteristics of science-gifted classes to general science classes, such as organizing general science classes around inquiry activities, supporting class materials such as MBL or tablets, reconstructing the classes using materials reflecting students' needs, and changing the textbook content and narrative style, to induce students' interest and curiosity. Based on the study results, ways to enhance the PES through science classes for general students were proposed.

However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.

Assessment of science laboratory environment was conducted with 539 students at middle and high school. Science Laboratory Environment Inventory(SLEI) was used as an instrument. The major findings of this study are as follows. 1. Mean scores obtained on each scale in the actual and preferred version of SLEI were relatively low, particularly on the scale of open-endedness, integration, and material environment. 2. Mean scores obtained on each scale in the actual version were lower than those in the preferred version. Score differences between actual version and preferred one were found to be significant statistically. 3. Boys and high school students perceived their laboratory environment with more open-endedness and less rule clarity than girls and middle school students respectively. 4. Girls preferred student cohesiveness at their laboratory more than boys. Highschool students wanted open-ended environment more than middleschool students. 5. Each scale of SLEI showed significant correlation with the scores of attitudes toward science. Particularly open-endedness was found to account for a significant contribution to the affective outcomes.

흡수분광분석장치와 반사분광분석장치가 결합된 형태의 복합분광분석장치를 제작하여 흡수분광분석과 반사분광분석의 성능을 서로 비교하였다. $Cu^{2+}$이온표준용액과 $Co^{2+}$이온표준용액들을 사용한 실험결과에 의하면, 분석대상성분의 농도가 너무 묽은 경우나 분석대상성분의 몰흡광계수가 충분히 크지 않은 경우와 같이 기존의 흡수분광분석으로는 정량분석이 힘든 시료용액에 대한 분광분석에 용이하게 적용될 수 있다는 사실을 확인하였다.

The relations of personality characteristics, such as shyness, sociability and self-disclosure and victimization by peers to loneliness in adolescents were examined with a sample of 485 second-grade highschool students(256 boys and 229 girls). They answered the questionnaires on loneliness as well as shyness, sociability, self-disclosure, and victimization by peers. All variables were significantly related to loneliness. The more shy they were and the more victimization by peers they experienced, the more lonely they were. The more sociable they were and the more self-disclosure they showed, the less lonely they were. All variables significantly predicted loneliness and the most influential predictor of loneliness was victimization by peers, indicating that the influence of victimization by peers on loneliness is so powerful for the adolescents.

본 연구는 남 녀 중고등학생이 인터넷 쇼핑몰에서 의복 제품을 구매할 때의 의복쇼핑성향과 의복쇼핑성향에 따른 불만족 요인을 밝힘으로써 청소년들이 인터넷 쇼핑몰을 이용하여 의복을 구매했을 경우 만족도를 높이는데 필요한 기초 자료를 제공하는데 그 목적이 있다. 본 조사는 설문지 응답방식으로 이루어졌으며, 인터넷 의복제품 구매경험이 있는 서울 수도권 소재의 중학교 3교, 고등학교 3교에서 학생 273명을 대상으로 조사하여 이중 응답이 불완전하거나 성실하지 못한 설문지를 제외한 총 265부가 최종 분석 자료로 사용되었다. 연구 결과를 요약하면 다음과 같다. 첫째, 청소년의 의복쇼핑성향은 '연예인 동조/유행추구 쇼핑성향', '또래 동조적 쇼핑성향', '편의적 쇼핑성향', '할인쿠폰 쇼핑성향', '경제적 쇼핑성향'으로 추출하여 군집 분석하여 '편리추구 집단', '또래 동조적 집단', '개성/유행추구 집단', '소극적 집단', '절약형 집단'으로 분류하였다. 여학생이 남학생보다 의복 동조성이 높으며 경제적인 가격으로 의복을 구매하는 것으로 나타났다. 고등학생은 경제적인 가격 때문에 인터넷 쇼핑몰을 이용하는 것으로 나타났다. 또한 청소년들은 인터넷 쇼핑몰을 통해 신발류, 상의류, 하의류 등을 주로 구입하는 것으로 나타났다. 둘째, 청소년들이 인터넷 쇼핑몰에서 의복 제품 구매후 불만족 요인은 '화면상 제품과 실제 제품의 차이', '교환/환불', '품질', '가격', '디자인과 색깔', '배송', '사이즈' 순으로 나타났다 '절약형 집단'과 '개성/유행추구 집단', '편리추구 집단', 여학생과 고등학생의 불만족 정도가 더 높게 나타났다.
