The purpose of this study was to identify the degree of recognition of the high school students about environmental and influential factors on it, selecting two regular schools and three vocational schools among the high schools in Busan area, questionnairing one class in the 10th, 11th, 12th grades of each school and analyzing the result. The result of analyzing the degree of knowledge, practice and recognition of seriousness concerning environment according to grade and gender is that the significant difference has been found in the degree of practice. The result of analyzing them according to maternal academic background is that the significant difference has been found in the degree of knowledge and a living standard and the style of housing have no effect on the environmental education, In the survey according to family style, it is shown that the students 'who live with their parents' recognize the seriousness of environment more. In the survey according to the experience of having the subject 'environment' in their school curriculum or not, it is shown that the significant difference has been found in the degree of knowledge. As the source of information on environment, mass media such as TV, magazines and newspapers have a great impact on the students. As the significant difference has been found in the degree of knowledge, practice, the recognition of seriousness from the viewpoint of the analysis on the survey according to the degree of the recognition on the necessity of the environmental preservation, it is shown that the more the students feel the necessity of environmental preservation, the higher the degree of knowledge, practice and recognition of seriousness on environment becomes, In the survey according to the kind of school, the significant difference has been found in the degree of knowledge, In the survey according to the degree of maternal concern on environment it is shown that the more concerns the mothers have, the more the students put what they learn into practice, In the survey according to the kinds of school, the significant difference has been found in the degree of knowledge. As the result of multiple regression analysis is summarized as below. 1. The variables influencing the environmental knowledge are the experience of having the class, 'environment', the recognition of the necessity of the environmental preservation and maternal academic background. 2. The elements influencing the degree of recognition of seriousness about environmental contamination are gender, the experience of having a class, 'environment' or not and the necessity of the environmental education. 3. The elements influencing the degree of practice are grade, information on environment, and maternal concern.

國民學校 敎師 自然 및 算數科 再敎育의 分析的 硏究 : Based on the Choong Buk Province

Our college has retrained many primary school teachers during 5 years is science, and during 4 years in case of mathematics. Many problems are found out in the process of retraining them in our school. This study is aimed to research the actual condition of the retraining and to find out the way to improvement from the problems. However, Our study will have some limitation as follows: (1) For our study, only 300 teachers are chosen from the total 1,869 attended at our college(Cheong Ju Teachers College) in 1976. (2) The administrational and financial affairs are analyzed only according to the Ministry of Education with UNICEF funds from 1972 to 1976, and (3) We didn't take any consideration of Ministry of Education Project in Suggesting the way of improvement. Following are some problems found in our study: 1) Throughout the nation, only 23% of primary school teachers were taught in science and mathematice reservice work during the 5 years, and it can be said that it takes about 20 years to retrained all the teachers without consideration of natural increase of teachers. 2) The proportion of selecting primary school teachers in all the country for this reservice training is extreme, for example, Jeju Province is 57.9%, Seoul 17.7%. 3) The proportion of woman teachers selected in Choong Buk primary school is only 3.5% of total woman teachers, who takes 32% of total Choong Buk primary teachers during 5 years. Therefore, it is said that the number is very little. 4) Some teachers have been reselected in the reservice training. In case of the Choong Buk Board of Education. the 6% of teachers selected once were reselected for 5 years. 5) When the test are enforced on attendants to get data before the reservice training. We could find that they didn't understand the basic concept of science except a grade under their charge. 6) In the process of inquiry study, they didn't know even the scientific terms of expectation and reasoning. 7) After 60 hours of reservice training course. We tested them about understanding of the contents of text, and their marks are from 10 to 100. the marks show large individual difference among them. 8) Some teachers may have neither teaching ability nor knowledge of the basic concept, that is 11.3% of total attendants are less than 30 marks in mathematics test. 9) It is too very large work to study reservice text during the 60 hours. 10) There are many difficult signs in the mathematics reservice text having no connection with the actual primary school mathematics text book. 11) In the reservice text of science, there are omitted the method of teaching materials production, the model of inquiry learning, and the evaluation method. 12) From the analysis of questionary response for finding the actual condition of administration of teaching materials, We could find out 15% of primary schools in Choong Buk Province do almost not prepare teaching materials, and 15% of its never put them to practical use. Therefore, We could say that total 30% of them have been teaching without teaching materials. 13) The 42% of attendants in mathematics class answer that they do not understand the new mathematical signs, and 42% of them answer the shortage of hours (60 hours) to understand their reservice text book. 14) The 25% of them answer that they teach children with cramming education, and almost of them want good teachers guide books. As mentioned above, there are found many problems to be solved for reservice training of science education in our country. Some of them will be solved in our study. So We find out its and We suggest the ways solving the problems as follows: A. On the administration of reservice training. 1) The reservice training work for primary school teachers is very significant and will have to be continued. 2) It will be done in not only summer vacation but also winter one for finishing immediatly all over the country. 3) The 60 hours of science reservice training course work are very short, and the classmember of attendants will be regulated. 4) The funds for reservice operation and travelling expenses for attendants will be realized. B. On selecting the attendants 1) When the attendants are selected, there will be consideration of age, rank, term of their service, sex and academic background. 2) as far as possible, it will be selected as homogeous groups, and it will be effective to teach them with division between class teacher and nonclass teacher. 3) When select attendants are it will be taken consideration of balance between city and province for the diffusion effect and parallel development in reservice training work. 4) It must give a chance to woman as same as to man teacher according to a rule of equal select chance. 5) The principal, instructor and school inspector will be reeducated for fixing of science curriculum. C. On reservice training text book 1) The text book must reedit moderatly for 60 hours, or the time of retraining for the text book finished will be extented. In our opinion, it is to be desired that the time have to be added. 2) The difficult signs must be omitted, taking into account for the mathematics knowledge and time of education period. 3) In the science reservice training text book, it must supplement the tack for framming of inquiry teaching plan, the method for making teaching materials, and the skill for replacing of teaching materials. D. For the curriculum management of science. 1) The Governmental Company must settle the shortage of science teaching materials in primary school. 2) For the charge of the old state of teaching method, the teachers must devote themselves to teach children without miscellaneous duties. 3) The authorities concerned (for example, Ministry of Education, Teachers College, etc.) must make guide books for science teachers, and supply them to primary school teachers. 4) It must be given the chance of long period reeducation to the incompetent primary school teachers, and problem will have to be studied under the situation of educational administration.

한정희,박혜선,고정민,김하영,강호경,이인규,박중열,홍성관,이재담,이기업 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.25 No.6

연구배경:Uncoupling protein(UCP)는 미토콘드리아의 내막에 위치하는 단백질로 세포내의 과다한 에너지를 열로 발산시키는 기능을 가진다. 최근 동물의 갈색지방조직에만 존재하는 UCP와 유사성을 가진 아형들(UCP2,3)이 사람에게도 존재함이 알려져 큰 관심을 끌도 있는데 이중 UCP3는 그 발현이 골격근세포와 갈색지방조직에만 국한된다. 본 연구에서는 UCP3가 체내 인슐린 감수성을 결정하는데 가장 중요한 조직인 골격근에 국한되어 발현되는 점에 착안하여 UCP3를 골격근세포에 과발현시켰을 때 포도당 대사에 어떠한 영향이 나타나는 지를 조사하였다. 방법:25주령의 8마리의 OLETF 백서를 대상으로 하여 4마리는 골격근에 adenovirus 2mL(1×10¹²pfu/mL)를 주사하여 대조군으로 하였고 4마리는 골격근에 재조합법으로 제작된 adenovirus­UCP3 2mL(1×10¹²pfu/mL)를 주사하였다(UCP3 과발현군). UCP3를 투여한 백서에서 먹이섭취가 증가하는 경향이 있어 그 전날 대조군이 먹은 야의 먹이만큼 투여하였다. 골격근에 adenovirus를 주사한 10일 후에 euglycemic hyperinsulinemic clamp를 시행하였다. Adenovirus­UCP를 C2C12 골격근 세포에 transfection시켜 UCP3를 C2C12 골격근 세포에 transfection시켜 UPS3­C2C12를 만들고 C2C12 골격근 세포와 UPS3­C2C12 골격근 세포에서 포도당 수송 및 당원합성을 측정하였다. 결과:UCP3 과발현 OLETF에서 체중이 감소하는 경향을 보였고 인슐린 감수성이 증가하였다. C2C12세포에서 기저상태 포도당 수송은 1.28±0.17μmol/L/min였고 100nM 인슐린으로 2시간 처리한 후 2.67±0.20 μmol/L/min로 증가하였다. UCP3­C2C12 세포에서는 기저상태 포도당 수송이 3.98±0.13μmol/L/min로 증가되었고 인슐린 처리 후 5.74±0.44μmol/L/min로 증가하였다. 인슐린을 처리한 UCP3­C2C12 세포에 P13K 억제제인 wortmannin을 첨가하였을 때 포도당 수송활성이 3.81±0.20μmol/L/min로 감소하였다. 기저상태 당원합성은 C2C12 세포에서 0.25±0.01μmol/L/min였고 인슐린 처리 후 0.45±0.01μmol/L/min로 증가하였다. UCP3­C2C12 세포에서는 기저상태 당원합성이 0.62±0.01μmol/L/min였고 인슐린 처리 후 1.26±454μmol/L/min로 증가하였다. UCP3­C2C12세포에 wortmannin을 첨가하였을 때 당원합성율이 0.80±0.04μmol/L/min로 감소하였다. 결론:UCP3 과발현이 OLETF 백서에서 인슐린 감수성을 증가시켰고 골격근세포에서 포도당 수송 및 당원합성을 증가시켰다. wortmannin을 첨가하였을 때 포도당 수송 및 당원합성이 감소함으로 보아 이 과정이 인슐린 신호전달체계인 P13K에 일부 의존함을 알 수 있었다. Background : UC P3 is a mitochondrial membrane protein expressed selectively in the skeletal muscle and brown adipose tissue. Since the skeletal muscle is the main organ determining insulin sensitivity in the body, it was hypothesized that UCP3 overexpression in skeletal muscle cells would improve glucose metabolism. Methods : An adenovirus-UCP3 was produced by a recombinant DNA method. OLETF rats were divided into 2 groups. Four rats were injected with the adenovirus-UCP3 (UCP3 group) and others were injected with the adenovirus(control group) in the skeletal muscle. The UCP3 group was provided with the same quantity of food as that consumed by the control group on the previous day. Insulin sensitivity was evaluated by the euglycemic hyperinsulinemic clamp method. In a separate experiment, glucose transport and glycogen synthesis we evaluated in C2C212 cells transfected with ether an adenovirus or the adenovirus-UCP3. Results : The insulin sensitivity improved significantly and the body weight decreased in the UCP3 group. The glucose transport and glycogen synthesis were higher in the UCP3-C2C12 skeletal muscle cells at the basal state. After insulin treatment, glucose transport and glycogen synthesis were also higher in the UCP3-C2C12 cells but the increments were reduced after treatment with wortmannin, a PI3K inhibitor. Conclusion : Insulin sensitivity was higher in the UCP3-overexpressed OLETF rats in the in vivo study. UCP3 transfection also increased glucose transport and glycogen synthesis in the cultured skeletal muscle cells by a PI3K dependent mechanism(J Kor Diabetes Asso 25 :460~468, 2001).

연구 목적 : 한국의 일 도시지역에 거주하는 청소년의 우울 증상의 유병률과 관련요인을 밝힘으로써 청소년 정신건강 증진을 위한 기초 자료를 수집하기 위하여 실시되었다. 방 법 : 연구 대상은 부천시에 거주하는 중학교나 고등학교에 재학중인 청소년 71,102명 가운데에서 무작위 집락 표본 추출법에 의해 선정된 2,203명이었으며, 이들에 대해서 CES-D(the Center for Epidemiologic Studies Depression Scale)와 사회인구학적 정보에 대한 문항이 들어 있는 설문을 실시하였다. 설문은 직접 학교를 방문하여 수행하였다. 선정된 2,203명의 청소년 가운데에 CES-D문항을 완성한 학생은 1,972명으로 반응률은 89.5%였다. 결 과 : 1) CES-D의 절단점을 16점으로 하여 계산한 '가능한' 우울 증상의 유병률은 중학생의 경우에 남학생 34.6%, 여학생 44.7%였으며, 고등학생의 경우에는 남학생 43.8%, 여학생 49.6%였다. 2) CES-D의 절단점을 25점으로 하여 계산한 '명확한' 우울증 증상의 유별률은 중학생의 경우에 남학생 18.4%, 여학생 20.7%였으며, 고등학생의 경우에는 남학생 21.4%, 여학생 23.9%였다. 3)종교, 인문계와 실업계의 여부에 따라서 우울 증상의 유병률에는 유의한 차이가 없었다. 4) 성,학년, 생활수준에 대한 자신의 평가, 가족의 구조, 성적에 대한 만족도의 다섯 가지 변수에 대해 CES-D점수가 16점 이상인 우울 증상의 유무에 따라서 로지스틱 회귀 분석을 시행하였을 때 성적에 대해 불만적 하는 군에서 매우 만족하는 군에 비해서 8.850배의 상대 위험도를 보였다. 생활 수준을 중하정도라고 대답한 군은 상이라고 대답한 군에 비해서 2.007배의 상대 위험도를 보였다. 여학생은 남학생에 비해서 1.307배의 상대 위험도를 보였다. 5) 우울 증상에 있어서 남학생과 여학생의 비율은 전체 군에서 1:1.38이며 중학생의 경우에는 1:1.88, 고등학생의 경우에는 1:1.13으로 나타났다. 고등학생에 있어 남학생의 우울 증상이 증가하는 것은 학업과 입시에 대한 부담과 관련된 것으로 생각되었다. 결 론 : 한국 일 도시거주 중고등학생에서 CES-D로 측정한 우울 증상은 남학생의 34.3%, 여학생의 47.5%에서 나타날 정도로 흔하다. 특히 학업 성적에 대해 불만족 하는 군에서 높은 우울 증상의 상대 위험률을 보이며, 고등학생에서 남학생의 우울증의 유병률이 높아지는 것은 이 지역 학생들이 학업에 대한 높은 부담을 가지고 있다는 것을 알 수 있었다. 따라서 이들에 대한 특별한 관심이 요구된다. Objective : We tried to see the prevalence and correlates of symptoms of depression in an adolescent population in Korea, and collected the basal data for mental health promotion of adolescents. Method : We sampled 2,203 adolescents among 71,102 adolescents living in Puchon City in Korea by the randomized clustered sampling method. The Center for Epidemiologic Studies Depression scale(CES-D) was used to measure depressive symptoms. The measurements were conducted through visiting schools. Of the 2,203 adolescents(aged 13 to 18) who were sampled, 1,972 persons completed CES-D and sociodemographic questions. The response rate was 89.5%. Result : 1) The prevalence rate of 'probable' depressive symptoms with cutoff point 16 was 34.3% in the boys and 47.5% in the girls. 2) The prevalence rate of 'definite' depression symptoms with cutoff point 25 was 17.4% in the boys and 20.6% in the girls. 3) We could not find any meaningful difference in the average of CES-D from the districts where they live, the course of their education, and their religions. 4) We used the logistic regression analysis to find the risk factor for adolescent depression in these samples. Among the variables degree, it was most important risk factor in adolescent depression to dissatisfy with their school degrees. Compared it with fully satisfied group, the odds ratio was 8.850. The group of mid to low socioeconomic status had the odds ratio 2.007 compared with high socioeconomic status. The girls had the odds ratio 1.307 compared with the boys. 5) The male versus female ratio was 1: 1.38 in the total students and 1 : 1.88 in the middle school students, and 1 : 1.13 in the high school students. The male versus female ratio was relatively low in the high school students. It was the result of the high prevalence of depressive symptoms in the high school boys, and it was due to the large burden to their school degrees. Conclusion : The depressive symptoms checked by CES-D were very common among adolescents in Korean urban area. The prevalence of depressive symptoms was 34.3% in the boys and 47.5% in the girls. The result that male versus female ratio was relatively low in the high school adolescents, and the group that were dissatisfied with the school degrees had high risk of depressive symptoms, revealed that the students had large burden to their school degrees and so they needed special concerns.

金善應,張仁鉉,許正 대구효성가톨릭대학교 1982 연구논문집 Vol.24 No.3

We obtained the following results drived from the previously describedobservation and analysis: 1. In the Service, the errors by the receive miss and double fault gave greaterin fluence on gain or loss than the gaining points by the ace service. 2. In the practical game, to reduce the losing Points by steady Placements ismore dosirable than the strong strokes. 3. The back-hand strokes are the most important in win or loss of gamebecause they attack on the general weak points of the opponent's back-handstrokes in the singles game. 4. The half volley, smash, lob, drop shot and no touch which are known asthe offensive plays don't occur many times in a games, So the defensive baseline play is usually prefered in the Korean women's single tennis games. 5. The losing points by errors give more influence of the win or loses morepoints than the passing shot. 6. In the games of the girl's high schools students, the winners gained morepoints the lost in the play of volley, passing and lob. The winners of adult women didn't make much mistakes in service, and thesimiliar phenomena was also occured in then fore-hand strokes and back-handstrokes.

Purpose: Asthma is a chronic airway inflammation. We evaluated whether systemic inflammatory patterns could reflect the nature of airway inflammation. We assessed characteristics of asthma according to systemic inflammatory patterns. Methods: A total of 413 children with asthma were enrolled in the study. Four systemic inflammatory patterns were classified according to eosinophil and neutrophil counts in peripheral blood. Children with neutrophil count≥5,000/μL were defined as the NEUhi group, those with neutrophil count <2,720/μL as the NEUlo group. The intermediate group with neutrophil count between 2,720/μL and 5,000/uL was excluded from the study. Children with eosinophil≥650/μL were defined as the EOShi group, those with eosinophil count<240/μL as the EOSlo group. The remaining patients were excluded from the study. The characteristics of asthma include pulmonary function test results, bronchodilator response, airway hyperresponsiveness, and atopy. Results: The EOShi group had a lower PC20 (provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 second [FEV1]), a lower FEV1, and a higher immunoglobulin E level rather than the EOSlo groups, although there were no significant differences between the NEUhi and NEUlo groups. The eosinophil percentages of the induced sputum samples were higher in the EOShi group than the EOSlo group and correlated with blood eosinophil counts. Conclusion: Eosinophilic inflammation was related to characteristics of asthma and sputum eosinophils. However, neutrophilic in- flammation reflected neither asthma features, sputum neutrophils, nor eosinophilic inflammation. Further studies on blood neutrophils involving asthma phenotypes in terms of more specific characteristics of asthma should be needed in children. (Allergy Asthma Respir Dis 2014;2:165-170)

Kwon, Ik Seon,Debela, Tekalign Terfa,Kwak, In Hye,Seo, Hee Won,Park, Kidong,Kim, Doyeon,Yoo, Seung Jo,Kim, Jin-Gyu,Park, Jeunghee,Kang, Hong Seok The Royal Society of Chemistry 2019 Journal of Materials Chemistry A Vol.7 No.40

<P>For the electrochemical reduction of CO2 (CRR) with high selectivity for HCOOH, In-Zn bimetallic nanocrystals (NCs) were synthesized as catalysts by <I>in situ</I> reduction of In2O3-ZnO NCs with various compositions. All In-containing bimetallic catalysts exhibited excellent selectivity to produce HCOOH, while Zn NCs favor CO production. A composition with In : Zn = 0.05 has higher catalytic activity than In NCs, with a faradaic efficiency of 95% and a HCOOH production rate of 0.40 mmol h<SUP>−1</SUP> cm<SUP>−2</SUP> at −1.2 V <I>vs.</I> RHE. The enhanced catalytic performance is in part ascribed to the fewer surface oxide layers, which increase the conductivity and facilitate the charge transfer. Density functional theory calculations revealed that the In-Zn interfacial sites make the HCOOH pathway significantly energy-favorable, which supports the higher production rate of Zn0.95In0.05 than that of In.</P>
