This study measured cardiovascular capacity, body composition, physical fitness with 191 middle-aged women between 30 and 59, living in G metropolitan city who have no abnormality as a result of physical examination with a view to health and strength factors by age and model of converting such factors into health age measures and obtained the following conclusions. 1. In VC comparison by age, there were statistically significant differences between groups and in comparison of SBP blood pressure. There were statistically significant differences in body fat% and abdominal fat% as a result of comparing body composition by age. 2. In comparison of physical fitness by age, there were statistically significant differences in grip strength, sit-up, side step, reaction time, trunk extension, sargent jump, close eyes foot balance. Vo2max, and subjects in their thirties showed higher scores in physical fitness measurement and the older they are, the lower their strength.

박명선,박태원 大韓口腔顎顔面 放射線學會 1990 Imaging Science in Dentistry Vol.20 No.2

This study was undertaken to determine (1) the usefulness of chromium intensifier to improve the dignostic quality of light radiograph; (2) the effect of chromium intensifier on density, contrast;and (3) the effect of various chemical concentrations on density. the following results obtained : 1. CHROMIUM INTENSIFIER is useful for intensifying and improving the diagnostic quality of a light dental radiograph. 2. The degree of intensification can be controlled by varying bleaching time, repeating the processing, varying the proportions of the potassium bicarbonate and hydrochloric acid solutions. 3. The image produced is black and permanent. 4. The intensifier increases density and contrast.

The purpose of this study was to explore the effect of informational intervention on coping of mother's stress in unplanned childhood hospitalization. Thirty four mothers of the hospitalized children, 24 months to 60 months old, were randomly assigned to experimental and control group. Child behavioral information and parental role information was given to experimental group by booklet and cassette tape. The state-trait anxiety was measured within 12 to 24 hours following hospitalization, the state anxiety was measured during from 24 hours to 48 hours, and the parent participation with care of children, and the parent support during invasive procedures was measured during 48 hours to 72 hours after hospitalization. The data was collected from May, 1997 to October, 1998 at B hospital in Seoul. Data was analyzed with X²-test, non paired t-test, ANCOVA test and Wilcoxon test using SAS program. Results were obtained as follows: 1. There were no difference in the state anxiety during the period of hospitalization and after discharging from hospital between experimental and control group. 2. Experimental group showed significantly higher scores on the parent participation with care of children than control group(P=0.03). 3. The parent support during invasive procedures of experimental group was significantly greater than that of control group(P=0.0167). The results suggest that information intervention regarding child behavioral information and parental role information may enhance both the parent participation with care of children and the parent support during invasive procedures.

This treatise is about studying the changes in military equipment in developed countries for an improvement in infantry's individual military equipment. To accomplish this research, I have analysed the military equipment from many other countries by collecting documents and pictures. The distinctive feature of current military equipment is that it is miniaturized cause of development in materials and various alloted tasks, standardized in various equipment for universal use, and complex functions in mixture of many equipment. Generally it is judged that there was many effect from the American equipment, and that the Europeans prefer complex and traditional shapes.

α-1,3-glucanase를 생산하는 미생물의 분리, 동정 및 배양조건

김명섭,신원철 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.4

토양으로부터 α-1,3-glucanase를 생산하는 미생물을 분리하여 동정과 배양조건을 검토하였다. 분리 균주는 회색 계통의 기균사를 형성하였으며 배면 색깔은 적갈색을 나타내었다. 또한 분리 균주의 생육온도 범위는 10~42℃이었고 생육 pH 범위는 pH4~10이었다. 그 외 catalase 양성, esculin, gelatin 및 casein 분해능이 있었다. 당의 이용성과 산 생성 여부를 검토한 결과 arabinose, dextrin 및 mannose에서 이용성을 나타내었고 cellulose를 비롯한 일부 당에서 산이 생성되었다. 분리 균주의 세포벽 구성 성분의 분석 결과 LL-DAP와 glycine을 함유한 세포벽 type Ⅰ으로 분류되었다. 세포벽 구성 아미노산 중 glycine과 alanine의 존재, 기균사의 형성, 수용성 색소 형성, melanoid 색소 형성 및 spore chain 형태 등의 결과로부터 분리 균주는 새로운 Streptomyces 속임을 알 수 있었다. 분리 균주를 이용한 α-1,3-glucanase의 생산은 초기 pH7, 37℃에서 48시간 배양하는 것이 약 0.65 units/ml로 가장 좋았다. A strain producing α-1,3-glucanase was isolated from soil samples. The strain has a grey aerial mycelium and showed brown color from the other side. The temperature and pH range for growth were from 10℃ to 42℃ and from 4 to 10, respectively. Arabinose, dextrin and mannose were utilized for growth. Analysis of cell wall components revealed that the strain was classified as type I. From the results, the strain was identified as Streptomyces sp. By using this strain, the maximum production of 0.65 units/ml for α-1,3-glucanase was achieved at 37℃ for 48 hrs.

퍼지추론규칙을 이용한 적응형 평가시스템

엄명용,정순영,이원규 한국컴퓨터교육학회 2003 컴퓨터교육학회 논문지 Vol.6 No.4

본 논문에서는 기존의 LCMS에서 사용되는 평가시스템에 퍼지 추론 규칙을 이용한 적응형 퍼지평가시스템(AFES : Adaptie Fuzzy Evaluation System)을 제안한다. AFES 는 학습자가 하나의 학습코스(learning course)에 들어가기 전에 퍼지진단평가(fuzzy diagnostic evealuation)를 통해 학습자에게 코스수준(course level)을 부여한다. 학습자는 코스수준에 따른 맞춤식 학습경로(learning path)로 학습을 종료한 후, 퍼지최종평가(fuzzy final evaluation)를 통해 최종성적(final grade)을 AFES 으로부터 부여 받는다. AFES, 의 가장 큰 특징은 최종성적의 점수 부여 규칙에 있는데, 만약 서로 다른 학습자가 동일한 문제 수에 대하여 같은 수의 정답을 냈더라도, AFES 는 125 가지 퍼지 추론 규칙(fuzzy reasoning rule)에 의거하여 탄력적으로 서로 다른 최종성적을 학습자에게 부여한다. We introduce an AFES(Adaptive Fuzzy Evaluation System) that applies an evaluation system used to existing LCMS(Learning Contents Management System) to a fuzzy reasoning rule. The AFES confers a course level on the learner through a fuzzy diagnostic evaluation before the learner enters a learning course. After the learner completes a learning course through the tailored learning path that is suitable for the learner’s level, the AFES confers a final grade on the learner by means of fuzzy final evaluation. The biggest characteristic of the AFES is a grade rule of the final grade. Although different learners get the same number of correct answers to the same number of questions, AFES flexibiv confers the different final grade on the learner by means of the number of 125’s fuzzy reasoning rules.
