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.

박창진,양재의,김경희,유경열,옥용식 한국환경농학회 2005 한국환경농학회지 Vol.24 No.1

본 연구에서는 시설하우스 폐양액이 고추의 생육과 양분 흡수에 미치는 영향을 평가하고 폐양액 관주시 부가적으로 얻을 수 있는 관개 효과를 산출함으로써 폐양액의 토양 시비에 따른 농업적 가치를 평가하였다. 시설하우스 폐양액의 토양 곽주시 Ca, Mg, K 등 염류의 증가로 인하여 pH와 EC는 상승하였고, 총질소는 암모늄태 질소와 질산태 질소의 증가와 함께 처리 후 100 mg kg^(-1) 이상 증가하였다. 고추 생육은 화학 비료 70% 및 폐양액 30% 혼합처리구와 화학비료 50% 및 폐양액 50% 혼합치리구에서 양호하였으며 양분 흡수도 동일한 경향을 나타내었다. 고추 수확량은 화학비료 70%, 및 폐양액 30% 혼합처리구에서 가장 높은 것으로 조사되었다. 1일 발생되는 폐양액(288 L 10 a^(-1)day^(-1))을 토양에 시용하여 증발산되는 수분을 보충할 경우 최고 409.86 m²의 면적을 관개할 수 있는 것으로 산출되었다. 이상의 결과를 통해 폐양액의 토양 처리는 화학비료 대체 효과와 폐양액의 정화 효과를 동시에 얻을 수 있으며 적정량 사용시 주변 환경에 미치는 영향을 최소화하면서 지속적인 처리가 가능할 것으로 판단되었다. Waste of the hydroponic solution from the plastic film house cultivation was recycled to grow the red pepper(Capsicum annum L.) in upland fields as supplement for plant nutrients and irrigation sources. Application of hydroponic waste solution increased the pH and EC of the soils, coupled with the increases in the concentrations of exchangeable cations(Ca, Mg, and K), total nitrogen, NH₄-N, and NO₃-N. Growth and yield of red pepper were highest when the treatment of chemical fertilizer(70%) was combined with hydroponic waste solution(30%). Amounts of the daily producing hydroponic waste solution were 2,880 L ha^(-1) day^(-1) from the experimental facilities and this could irrigate 409.86 m?of area to compensate for the amount of water loss by evapotranspiration(3%). The overall results demonstrated that hydroponic waste solution could be recycled as plant nutrients and irrigation water resources for enhancing soil fertility and environmental quality.

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.

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.

ZnO첨가에 따른 0.67PMN-0,33PT 세라믹스의 상전이 온도, 유전 및 압전 특성의 변화를 조사하였다. ZnO를 첨가하지 않은 시편의 경우 소결 온도가 1,100℃인 반면, ZnO를 0.2wt%첨가한 시편의 경우 1,000℃에서 이미 소결 완료 되었으며 이것은 ZnO가 소결을 촉진시키는 재료로 작용하였으며 이러한 결과는 시편의 수축률 기공률, 밀도측정 결과로 부터 확인할수 있었다. XRD 분석결과ZnO를 첨가한 시편에서 pyrochlore상과 어떠한 불순물도 존재하지 않았으며. 이는 Columbit precursor법과 PbO 과잉첨가법을 병행하였기 때문이며, ZnO 첨가에 따라 결자상수가 증가하고T_(max)가 고온쪽으로 이동하는 것으로 보아 Zn^(2+) 의 일부가 Mg^(2+)자리에 치환하여 들어간 것으로 생각된다, 온도에 따른 유전특성 결과로 부터 소량의 ZnO만을 첨가 하여도 ZnO를 첨가하지 않은 시편과 비교해 볼때 현저한 유전특성의 향상을 보였고 900℃에서 2시간 소결한ZnO 02wt%첨가 시편은 최대 유전상수가 22,000이었다. ZnO첨가에 따른 0.67PMN-0.33PT세라믹스의 압전특성 결과로부터 0.2wt% 첨가한 시편의 경우 36%의 Kp값을 보였고, 0.2wt%를 초과 하면서 부터는 점차 감소하는 경향을 보였다, 이러한 압전특성 결과로 부터 ZnO는 물질내에서 donor및 acceptor로 작용하고 있다는 것을 알 수 있었다.

Many of college students have the cognitive deficits, one of which is the impulsiveness, in the process through which they solve their problems in the daily life. This study attemted to develop the program for the purpose of improving college students' thinking skills. Also, the program was intended to encourage the college students to reduce their impulsiveness, and to help them maintain the rational reasoning solving the complex of problems. For this purpose, researchers examined the difficulties which college students had in the process of their thinking, focussed on their impulsiveness in particular, based on the findings of preceding works related to the thinking skills, including some of programs for improving the thinking skills and intelligence. As a result, a program was developed to improve the thinking skills of college students in order to reduce their impulsiveness. This program was composed of two parts, each of which included five units. Part One, titled "Human Life and the Limited Rationality", was focused on training college students with metacognition or cognitive style. In this part, the trainees explored those phases passed on the human problem solving and the sources of impulsiveness. This part included five units: (1) Introduction; (2) Journey in the universe of learning; (3) Uncertainty and impulsiveness; (4) Human problem solving; and (5) Human information processing and limited rationality. Part Two, titled "Resolution of the Limited Rationality and Intellectual Limitations of Human Being", was focused on training college students with cognitive strategies. In this part, the trainees searched for the general cognitive strategies with which they would learn each unit, and used it to resolve the limited rationality of human being and thus to solve the problems more efficiently. This part included five units: (1) Search for strategies to resolve the intellectual limitations of human being; (2) Utility of the external representations; (3) Application of strategic knowledge of inferences; (4) Resolution of the inferential baises; and (5) Evaluation and termination. A pilot study attempted to verify the effectiveness of the training program. Subjects were 118 sophomores of a national university in Chon-buk. They were assigned to an experimental group(N=56) and a control group(N=62) to test the effectiveness of the training program. The experimantal group received 12 sessions of training instruction for 50 to 60 minutes each week. The control group was given no intervention. After training sessions, they were given a cognitive style (impulsiveness) scale as well as a reasoning test, and also checked a questionnaire which asked the participants to express their opinions of the training program. The findings of the study might be summarized as follows: 1. The program seemed to contribute posively to change participants' cognitive style, particularly to reduce their dysfunctional impulsiveness. 2. The program seemed to contribute substantially to improve participants' performance of reasoning tasks. 3. Many of participants (about tow-third) of the participants reported to have a novel feel- ing on the program, to perceive the program different from the existing curriculum, and also to take some benefits from the program. However, this study suggested several recommandations as follow: 1. It is necessary to verify the effectiveness of the program on the basis of a valid design of experiment. 2. It is necessary to take a effort to extend the breadth and depth of the program, including a discussion of the functional impulsiveness. 3. It is necessary to establish the reinforcement schedule in order to encourage the participant to engage in the program actively.
