The purpose of this study is to examine the effects of the Portfolio applied science instruction on the students' scientific affective domain and perceptions of portfolio in elementary schools. Portfolio applied science instruction of the 6th grade science unit 'Environment pollution and Nature protection' was developed for this study. Traditional instruction was implemented to the control group and portfolio applied science instruction was implemented to the experimental group. Pretests of the scientific affective domain were administered to both groups. The treatment was given for about seven weeks for both groups. Instruments about scientific affective domain were administered to both groups. A questionnaire on perception of portfolio applied science instruction was given to the experimental group after the treatment. The results were analyzed using t-test on the students' scientific affective domain. The results of this study are as follows: 1. Portfolio applied science instruction program for elementary schools was developed. Students themselves determine the portfolio learning goal in a portfolio applied science instruction. Students construct the portfolio and they evaluate themselves and other colleagues. Also teachers go on portfolio applied science instruction considering portfolio purpose, concepts, evaluation. 2. There was not a statistically meaningful difference between an experimental group and a control group on the students' scientific affective domain. In three sub categories of a scientific affective domain, the science perception, the interest on science and scientific attitude, there were not statistically meaningful difference among them. 3. As the results of the questionnaire on perceptions of portfolio, they didn't understand it very well but after learning portfolio, they showed positive attitude to perceptions of portfolio. Students in portfolio applied science instruction like more the portfolio applied science instruction than general instruction. 4. Portfolio applied science instruction has an useful value as a method of teaching and evaluation. Students and teachers can produce various portfolios products in portfolio applied science instruction. As a conclusion, portfolio applied science instruction was not statistically meaningful on the students' scientific affective domain, but it gives positive effects on perceptions of portfolio in elementary schools. Therefore, portfolio has an educational value as a method of teaching and evaluation for students' growth. In the future, teachers and students must have interaction and feedback in portfolio applied science instruction.

The purpose of this study is to grasp the relationship between the amount of physical activities perceived by male workers and their body-mass index. To achieve such a purpose, this survey was conducted on 330 male workers by means of questionnaires during the period of July 1 to July 20. And collected data were sampled by matched sampling technique by sex, age, education and perception of socioeconomic class. Thus 70 selected data were statistically analyzed by CTAS(Computer Aided Teaching for Statistics). The obtained results are as follows. There were negative relationships between the amount of physical activities at work or after and body-mass index; Pearson correlation coefficients of the former and the latter were -0.33 and -0.25 respectively. The above results imply that the harder workers think their physical activities at work, teh lesser they perform their physical activities after work and the hihger their body-mass index will be increased. Therefore it is desirable that health management programs for workers should be developed into connecting their work sites with their homes and focused on the physical activities after work much more.

箱子桁의 壓縮플랜지 挫屈에 대한 模型實驗解析

鄭熺孝,南文熙 慶尙大學校 1986 論文集 Vol.25 No.2

As box girder is the structure constituted by thin plates, security of the structure is greatly influenced by the collapse on compressional flange. The collapses of flange bring about stress concentration at upper sides of web, morever, if in case of the imperfect plate they were increased, tensile stress would occur at the middle point of upper flange and develop collapse failure at upper sides of web and projections of upper flange. The ratio a/b(both side-lengths of plate) of the collapse is decided by the distance of diaphragm, when load is increased up critical load the ratio a/b approaches 0.70. Designing the box girder, engineers must take into the influences of side stress that imperfects of flange and eccentric load arouse.

위성자료와 대기대순환 모델결과로부터 추정된 계절적 연직 p-속도

기상위성에 탑재된 Microwave Sounding Unit(MSU) 복사계로 관측된 채널1(50.3GHz) 밝기온도(T₁)와 채널2(53.74GHz) 밝기온도(T₂)간의 상관계수값을 대기대순환 모델의 연직 p-속도(ω)값과 비교 ·분석하여 해양에서의 연직운동에 대한 경험식을 도출하였다. 여기서 위성자료 및 모델의 ω결과가 각 위도별로 평균된 상태에서 상호 비교 되었으며, 이중 모델값은 1979-88기간의 GLA GCM및 1980-88기간의 ECMWF GCM에서 분석된 것이다. 구름 및 강수활동과 관련 있는 T₁과 T₂간의 상관값과 ω값의 비교를 통해 열대수렴대(ITCZ)와 남태평양 수렴대(SPCZ)의 계절별 발생위치 및 세기를 추정하였으며, 또한 대순환 모델 개선을 위한 위성자료의 활용 가능성을 조사하였다. 육지에서 구름 및 강수가 위의 두 채널 밝기온도에 미치는 물리적인 영향을 흡수와 산란 과정을 함께 포함한 복사전달모델을 사용하여 평가하였다. 표면 방출율(ε)이 1인 육지에서는 해양의 경우((ε=∼0.5)와 다르게, 두채널 온도값 사이에 높은 양의 상관(∼0.98)이 나타났으며 이는 강수에 의한 광학적 깊이가 증가할수록 T₁과 T₂가 모두 감소하기 때문인 것으로 해석되었다. 이러한 결과는 육지에서 두 채널의 밝기온도가 지상온도와 높은 상관을 갖게 되어 지구 온난화 분석에 유용하게 사용될 수 있음을 의미한다. 또한 대순환모델 결과에 위성자료 분석을 보완할때, 역학적인 대기순환에서 침강과 대류지역이 보다 정확하게 시뮬레이션될 수 있다. A formula to estimate the vertical p-velocity (ω)is derived from satellite brightness temperature data of the MSU Channel 1 at 50.3GHz(T₁) which have been observed by the Microwave Sounding Unit(MSU). The formula has been formed by comparing outputs from two general circulation models of the Goddard laboratory for Atmospheres(GLA GCM)and the European Center for Medium Range Weather Forecasts (ECMWF)with 9-10 years of microwave data. Here monthly values of the GCM outputs and satellite data which have been zonally averaged again are compared with each other. The location and intensity of Intertropical Convergence Zone(ITCZ) and South pacific Convergence Zone(SPCZ) has been inferred from the comparison of the vertical p-velocity and the correlation coefficient between T₁and T₂related to the effect of hydrometeors. Possible utilizations of satellite data for the improvement of GCM have been also examined. In order to evaluate the effect of hydrometeors on the brightness temperature over land, a radiative transfer model is utilized to simulate the observation of the T₁and T₂. The high correlation (0.97-1.00) between the two temperatures occurs over land due to high surface emissivity(ε=∼1.0), compared to over ocean(ε=∼0.5). The reason is that the extinction due to hydrometeors over land causes the decrease in brightness temperatures of both channels. These results imply that brightness temperature of the two channels on land can be alternatively available for analyzing global warming, highly related with the surface temperature. If satellite data compensates for the analysis of GCM, more precise simulation for the convective and subsiding areas existing in a dynamical atmospheric circulation can be expected.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

The content of oxidation-reduction in the chemistry textbooks from middle school to college was analyzed to see the effective connection of curricular articulation. For this purpose, oxidation-reduction content between the school unit were selected in chemistry textbooks and formed five types of classification from groups of "first concept", "same concept", "overlap", "development" and "gap". The result indicated that there was a deep big gap from middle school to senior high school and the effectiveness from senior high school to college was looked acceptable. Finally, the new concept maps between the school unit were suggested.

We developed an occupational therapy tool to maintain and improve the cognitive function for the elderly who have senile dementia. 86 elderly people took a mininal mental state examination (MMSE) for the therapy to perform the occupational therapy, and divided into three groups based on avarage ages and MMSE values. The occupational therapy was treated three times per week for 10 weeks. The results showed that there were significant differences in the performing scores before and after the treatment ; the scores for the occupational therapy were increased significantly (p<0.001) and the performing time was shortened from 6-week throughout 10-week regimen. This study was to examine the effect on the activity of antioxidant enzymes by occupational therapy. The activities of antioxidant enzymes such as catalase, Glutathion-6-phosphate dehydrogenase (G6PDH), and superoxide dismutase (SOD) were increased to the normal standard by the occupational therapy for the elderly having dementia. The recovery of activities of antioxidant enzymes was obvious in severe demented elderly compared to those in normal or mild demented elderly. These results suggest that the occupational therapy had an beneficial effect on the protection against the oxidative stress especially for severe demented elderly, and the occupational tool need to be modified so as to improve the protection against the oxidative stress for normal and/or mild demented elderly.

김대진,김원,윤수정,고효진,최보문,전태연 대한신경정신의학회 2000 신경정신의학 Vol.39 No.4

기존의 항정신병약뮬인 haloperidol이나 clozapine과는 약물학적 특성이 다른 대표적인 약물인 risperidone을 사용하여 정신분열병 환자가 치료 전과 4주 치료 후에 어떤 면역학적 차이를 보이는지 6가지 cytokine의 혈장 농도를 측정하여 알아보았다. 방법: 1999년 2월부터 1999년 5월까지 카톨릭대학교 대전성모병원 정신과에 입원한 환자 중 DSM-IV 진단 기준에 의해 정신분열병으로 진단된 환자 25명을 대상으로 하였다. 입원 다음날 아침 8시 risperidone 투여전의 기본적인 cytokine농도를 측정하기 위해 혈액을 채취하였으며 제 2병일에 risperidone 2mg, 제 4병일에 4mg, 제 6병일에 6mg으로 증량하는 방식을 항정신병약물 치료를 하였다. 임상평가는 risperidone 투여 전과 투여 4주 후 정신과 전공의가 각각 PANSS 검사를 시행하였다. 혈장에서 IL-1β,IL-2, IL-6, IL-12, INF-□, TNF-α의 정량 측정은 ELISA kit (Endogen Inc., Woburn, MA, USA)을 사용하여 quantitative ELISA법으로 하였다. 결과: risperidone을 4주간 투여 후 환자 혈장 IL-12 농도가 유의하게 증가되었고 나머지 cytokine 농도는 유의한 변화가 없었다. 결론: 저자들은 연구에서 risperidone 치료 후 IL-12가 증가된 것은 이러한 항정신병약물치료가 면역반응 을 활성화시키는 역할을 한 것으로 시사된다. Objectives: This study was carried out to evaluate immunologic difference between baseline and after 4 weeks drug treatment with atypical antipsychotics(rispreidone) by measurement of serum concentration of 6 cytokines. Methods: The subjets were composed of 25 patients who are admitted at Dajeon St's Marys hospital of psychiatry department and diagnosed as schizophrenia by DSM-IV diagnositc criteria. We measured serum IL-1β, IL-2, IL-6, IL-12, INF-□, TNF-α concenatrations by quantitative ELISA method using ELISA kit(Endogen In., Woburn, MA, USA). The two psyciatrists per-formed PANSS examination between baseline and after 4 weeks risperidone treatments. Results: The serum level of IL-12 was increased significantly after medication of 4 weeks and the serum concentration of IFN-□ showed the tendency of decreasement but not significant. The serum level of the other cytokines showed no significant change. Conclusion: We spectulate that the increasement of IL-12 may contribute to role of activa-tion of immune response by treatment of antipsychotic medication(risperidone). This study is first trial of IL-12 study in neuropsychiatric field and IL-12 which play impor-tant role of immune response becomes interesting subjects in immune research.
