Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

Process characterization of waste plastics pyrolysis in a bench scale fluidized bed test unit was investigated. Feasibility of commercial scale process such as proper feeding system and reaction control ability were analysed and confirmed based on the reaction characteristics varying with the plaxtics and system assemblies. Eight pure or waste plastic samples were collected from the industrial waste plastics generation source in Korea. Selected samples were HDPE, LDPE autobovile interior, XLPE electric wire coat, synthetic rubber, EVA shoe sole, PS(monomer and styrofoam) and ABS. The pattern of decomposition reflected composition and molecular structure of plastics. Decomposition of polyolifin produced linear paraffinic and olefinic compounds. Recovery of styrene monomer and aromatic compounds were attained from the phrolysis of PS and ABS. However, secondary reaction was monitored was monitored even from the pyrolysis of aliphatic samples of XLPE and EVA.

김혜숙,윤영임,조은정,최윤희,오미영,김영관 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

This research was carried out to find out the possibility of using Faraday's law in analyzing the electrocoagulation system. Bench-scale reactor equipped with aluminum electrode plates was operated using synthetic wastewater which received sodium chloride for conductivity adjustment. Phosphate was added to the wastewater to induce the precipitation with Al. The amount of aluminum dissolved from the electrodes could be predicted by Faraday's law with a difference less than 5%. This difference was greater at a higher electric current, probably due to the increased solution temperature. However, effect of pH on the dissolution of the aluminum was negligible. The result of this study suggested that the operating condition of electrocoagulation system could be developed using the Faraday's law when the pollutant concentration is given.

학습장애를 가진 초등학교 남학생의 자아상 개념과 우울-불안 특성 조사

신성웅,김봉수,성덕규,정영,유희정,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

학습장애를 가진 86명의 초등학교 남학생과 52명의 정상적인 초등학교 남학생의 자아상과 우울,그리고 상태-특성 불안에 관하여 피어스-해리스 자아상 척도, 소아우울척도(이하 CDI), 상태-특성불안 척도(이하 STAI)를 이용하여 조사하였다. 피어스-해리스 자아상 척도의 총점에서는 두 군 사이에 차이가 발견되지 않았으나, 지적 및 학업 상태 항목과 신체적 외모, 행복과 만족 소척도에서는 두 군 사이에 의미 있는 차이가 관찰되었다. 소아우울척토의 총점과 그 소척도 중 부적합함, 무쾌감증, 부정적인 자기 존중 항목에서 학습장애 아동이 정상 아동보다 더 높은 점수를 나타내었다. 상태불안은 정상 아동보다 학습장애 아동에서 높게 보고되었으나 특성 불안에 대해서는 차이를 보이지 않았다. 정상 아동에서는 나이에 따른 자아상과 우울척도, 불안척도의 의리 있는 변화가 관찰되지 않았으나, 학습장애 아동에서는 피어스-해리스 자아상 척도와 그 소척도의 대부분이 통계적으로 의미 있게 감소하였고, 소아우울척도의 부정적 감정과 무쾌감증, 부정적 자기 평가, 상태 불안, 특성 불안 등은 연령과 의미 있는 양의 상관관계를 나타내어서 학년이 올라갈수록 자아상은 저하되고 우울과 불만은 느끼는 강도와 범위가 증가하는 양상을 보였다. 두 군 모두에서 소아우울척도는 피어스-해리스 자아상 척도의 총점과 그 소척도들과 의미 있는 역의 상관관계를 나타내었고, 상태불안과 특성불안과는 정의 상관관계를 나타내었다. 조사 결과 학업과 관련된 자아상의 문제와 자신이 남들과 당당히 맞설 수 있는 자신감의 문제가 학습장애에서 더 많이 나타났고, 나이가 들수록 자아상이 저하되며 불안과 우울은 증가하는 것으로 나타났다. 회귀분석 결과 학습장애 아동의 자아상을 설명하는 변수들로는 나이와 자아상 척도의 행동문제, 지적 및 학업상태, 불안, 인기도, 행동과 만족, 그리고 소아우울척도의 부적합함, 대인관계문제, 부정적 자기-존중 및 상태 불안인 것으로 드러나서 학습 장애 아동의 자아상은 학업 문제와 자신을 또래와 비교하여 겪는 스트레스로 인해 부정적인 영향을 받는다는 것이 확인되었다. 결론적으로 학습장애를 가진 초등학교 남학생은 정상 초등학교 남학생보다 자아상이 낮고 우울과 불안을 더 많이 느끼며, 이런 차이는 학년이 올라갈수록 커졌다. 학습장애에서 우울증과 불안 장애가 많이 동반되기 때문에 임상에서 학습장애 아동을 치료할 때 정서 장애의 동반 여부를 확인하고 이를 적극적으로 치료하는 것이 중요한 과제이다. 중심단어 : 학습장애 ㆍ 자아상 ㆍ 상태-특성 불안 ㆍ우울증. We investigated the self-concept, subjective depression, and state-trait anxiety of the school boys with learning disabilities (abbr. LD, n=86) and compared them with normal boys (n=52) using Piers-Harris Self-Concept Inventory, Child Depression Inventory (abbr. CDI), and State-Trait Anxiety In-ventory (abbr. STAI). With regard to Piers-Harris Self-Concept Inventory total scores, there was no significant difference between two groups, but normal boys showed higher scores in intellectual and school status, physical appearance, and happiness-satisfaction subscales than patients with LD. The male patients with LD showed significantly higher ratings in CDI total scores, and CDI subscales - ineffectiveness, anhedonia, negative self-esteem than normal children. The patients with LD reported significantly higher state anxiety, but not trait anxiety. Correlation analyses revealed that self-concept decreased over time, and depression-anxiety increased across grades in the patients with LD, but not in normal children. Especially, negative mood, anhedonia, negative self-esteem subscales of CDI, and state-trait anxiety showed significant positive correlation with grades. In both groups, CDI scores were inversely correlated with Piers-Harris Self-Concept and positively with State-Trait anxiety. In conclusion, self-concept problems which were related with school achi-evement and self-esteem were more abundant in the patients with LD than normal children, self-image problem, depression and anxiety increased across grades. According to regression analysis, age, behavior subscale, intellectual - school status, anxiety, popularity, happiness- satisfaction, CDI-ineffectiveness, interpersonal problem, negative self-esteem, and state anxiety could explain the self-concept in the patients with LD, not in normal children. So, the self-concept of the patients with LD were found to be related to the school achievement and stress when comparing with peers. In conclusion, elementary school boys with LD showed lower self-concept, higher depression and anxiety, and these differences increased across grades. Since the patients with LD have concomitant depression and anxiety disorders, it is important that comorbidity with emotional problems should be explored and managed properly. KEY WORDS : Learning disability ㆍ Self-concept State ㆍ trait anxiety ㆍ Depression.
