This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Every interventional procedure can result in infectious complication even though its incidence is very low. Increases in both indication of procedures and number of immunocompromised patients are likely to result in increase of infectious complications. However, no randomized controlled trials to evaluate the effectiveness of prophylactic antibiotics in interventional procedures have ever been performed. This study was performed to investigate the actual pattern of practice and awareness of medical providers concerning the antibiotic prophylaxis following vascular and nonvascular interventional procedures. A questionnaire regarding prophylactic antibiotic usage was sent to the interventional radiologists in 40 hospitals. A total of 12.2-30.3% responders used prophylactic antibiotics for vascular procedure. More than 80-90% of responders answered that vascular procedures except catheter insertion, are not clear indications of prophylactic antibiotics, In contrast, 31.3% and 51.5% of responders used prophylactic antibiotics for genitourinary and biliary drainage respectively. About 60-70% of responders considered both genitourinary and biliary drainage as clear indications of antibiotic prophylaxis. Further study assessing the appropriate antibiotic usage in interventional procedures is warranted.

Since ancient times Trichosanthis Radix has been used in traditional herbdrung as an antitumor and immunologic stimulating agent. Lectin was purified to homogeneity from Trichsanthis Radix by ammonium sulfate precipitation, DEAE-Cellulose chromatography and Sephadex G-150 gel filltration. The major amino acid was tyrosine and some aspartic acid, glutamic acid and saccharides were also present. Trichosanthis Radix Lectin (TRL)strongly stimulated activity of human erythrocytes, lymphocytes, and thrombocytes. In addtion, agglutination of gram negative Escherichia coli and Pseudomonas ararugimosa was shown, but proteus, Hemophilus influenza and Staphylococcus aureus were not agglutinated. Folloaing injection of TRL into ICR mouse, granulocyte was increased by 87.5% and the number of lymphocyte was increased by 25-28%. These results suggest that TRL may have stimulating effects on the general immune systems.

Science textbook in South Korea(5th revised) and North Korea(current) are compared and analysed. The present study shows differences between both science textbooks which may be utilized in future after unification of the two countries. In primary education the south has more than the north in the page number of the textbook. In North Korean educational systems, the idolization of Kim Il-Sung and Kim Jung-Il is apparent. The textbooks of South Korea are made of better materials than those of North Korea. Covers, and illustrations are also of higher quality. Compositions are common in both country's textbooks as they deal with common everyday subjects. South Korean learns science uniformly. However, North Korean takes the unconnected, undeveloped, and ideological pass and also promotes the cramming as a system of education. In scientific terms, North Korea's textbooks show the differences in name, presentation.

Since 1980s, many studies have been attempted to explore the nature of thinking or intellectual skills of human being and to develop the program with the purpose of improvement on these skills. these studies have been expected to have a great influence on the educational effort of diagnosing and resolving a defect in underachiever's academic performance. Based on these expectations, this study was attempted to test the validity of various scales in diagnosing the impulsiveness and to develop a training program for the purpose of decreasing it and to evaluate the effectiveness of that program with underachievers. Subjects were 20 underachievers (10 in Ex. group and 10 in Co. group), of a middle school at Chonju city, who were rated to be more impulsive than other students by their teachers, using a teacher-rating impulsiveness scale. Before and after training, all subjects performed 3 tasks (Arithmatic, Logic, and Comprehension monitoring task), which were used to diagnose their impulsiveness. During 8 weeks, subjects in Ex. group spent 4 hours a week on the impulsiveness-reduced training, which was based on Baron's normative model of cognitive style and Parlinscar and Brown's comprehension monitoring strategies. Material was a expository text which was drawn from texts in history and geography. The results of this study can be summarized as follows: 1) The latency and accuracy (% error) composites for the Arithmatic and Logic correlated significantly with teacher-rating impulsiveness. Accordingly, it was found that these measures are valid. Also, these measures correlated significantly with the latency and accuracy (% correct) measures for the comprehension monitoring task, which represented a high correlation of cognitive style (Impulsiveness) with metacognitive skill. 2) The impulsiveness-reduced training was relatively successful in making the subject take time while problem solving, especially for Arithmatic and Logic. The training did not have a significant effect on accuracy, although the effect was in the predicted direction. But a additional analysis looked for a moderating variable that might influence the effect of training on accuracy : The training improved accuracy more for impulsives than for nonimpulsives. These results implied cognitive style can be modified.

This study was attempted to identify the collegians' existentiality. For this study, 212 subjects was sample among freshmen and sophomore in Chonbuk National University. Existentiality test was administered to the subjects, and results of status of life affairs and personality depended on results tested in the time of orientation period for freshmen. Factor Analysis and ANOVA methods were used in this study. The major findings can be summarized as follows: 1. The core factors identified as result of factor analysis on collegians' existentiality were composed of such contents as rules and norms and sensitivity. 2. Four factors are extracted : factor Ⅰ was defined as existentiality on norm; factor Ⅱ as existentiality on crisis and danger ; factor Ⅲ as existentiality on value and meaning; and factor Ⅳ as existentiality on attitudinal value, respectively. 3. As for the comparison of existentiality factor according to status of life affairs variables, there is no significant difference in existentiality according to sex. In general, sophomore have higher existentiality in factor Ⅳ than freshmen. Group with religion have higher existentiality in factor Ⅰ than their counterpart. Self decision-makers on their school have higher existentiality than others-depended students. Students' socioeconomic status, satisfaction on their majar, and future career have no relation to their existentiality. 4. As for the comparison of existentiality according to students' personality traits variables, it was revealed that personality variables relaing to the existentiality are validity, family relation, emotional stability, and mood. These findings have some implications for the study in counseling. For collegians' counseling, studies considering such existential tratis as collegians' individuality and uniqueness are needed.

난용성 유기 화합물의 용해, 확산 및 생분해에 대한 Rhamnolipid (Biosurfactant)의 영향

박종옥,김경순 경성대학교 2001 論文集 Vol.22 No.1

Pseudomonas aeruginosa rhamnolipid biosurfacnant enhanced solubility, dispersion, and biodegradation of organic compunds with limited water solubility. Rhamnolipid-enhanced organic compound dispersion was found to be dependant on biosurfactant concetration, pH, incubation time, structure of surfactant. All surfactants reduce the surface tension of a liquid medium. The surface tension of rhamnolipid soution was quite sensitive to pH. Organic compounds dispersion in the presence of rhamnolipids was also influenced by pH. Rhamnolipidbiosurfacnant enhanced the aqueous dispersion of octadecane by more than 4 orders of magnitude, from 0.009 to 320 ㎎/liter. Mineralization rates can be increased significantly by rhamnolipid-enhanced octadecane dispersion. The fourfold increase in mineralization was not nearly as high as the 〉104-fold increase in the aqueous dispersion of octadecane. Therefore, although rhamnolipid increase in the dispersion of octadecane, the octadecane is still not freely bioavailable. These results indicate rhamnolipids may have potential to facilitating the biodegradation of hydrocarbons in contaminated soil as well as aqueous environments.
