This study was conducted in order to compare weight control behaviors, eating disorder risk, and depression in female adolescents according to dieting experience during the last year. The subjects were 707 students attending a girls' high school in Seoul, and all the information was collected by self-administered questionnaire. Eating disorder risk and depression were determined by using EAT-26 (Eating Attitude Test-26) and PHQ-9 (Patient Health Questionnaire-9), respectively. Data were compared between subjects with experience of dieting (320) and those without (387). More of the subjects with dieting experience were unsatisfied with their own body weights (76.9% vs. 44.2%, P<0.01) and weighed themselves frequently (P<0.01) compared to those without diet experience. EAT-26 ($11.63{\pm}8.3$ vs. $5.99{\pm}4.7$, P<0.01) and PHQ-9 scores ($7.05{\pm}4.6$ vs. $6.00{\pm}4.4$, P<0.01) were higher in subjects with dieting experience compared to their counterparts. Therefore, we concluded that dieting is associated with several undesirable psychological aspects such as eating disorder risk and depression in adolescent girls, and thus providing proper education is urgently needed to emphasizing importance of healthy weight and the danger of unnecessary dieting.

Purpose: The purpose of this study was to investigate the effect of microcurrent on fatigue of muscles in people who were flat-footed during gait. Methods: 10 flat-footed university students volunteered to participate in this study. 10 flat-footed subjects were divided into 2 groups, one group was experimental group of 5subjects(This group put on microcurrent induction shoes but the subjects were not able to feel the current.) and the other group was the control group of 5subjects(This group put on the general shoes which were similar in shape but microcurrent was not induced.) to perform double blind test and random sampling. Their gait muscle fatigue of 6 regions (vastus medialis, gastrocnemius, tibialis anterior, biceps femoris, erector spinae, and rectus abdominis muscle.) was measured by EMG MP150, Delsys Inc Boston, USA during walking and then they carried out the Harvard step with a platform (It was a arbitrarily made wooden platform of 100cm long, 50cm wide, 60cm high. They carried out climbing it for one second and descending it for one second by using the Metronome program, total 5minutes) for 5minutes. Right after that, the subjects walked on a treadmill at a speed of 4km/h for 10minutes and then their gait muscle fatigue of 6regions was assessed while they were walking on the ground as equally as before exercise. Results: The experimental group has resulted in lower average differences in gait muscle fatigue before and after exercise than those of the control group average 12.24Hz(P=0.009) at vastus medialis, average 8.52Hz(P=0.016) at gastrocnemius, average 9.16Hz(P=0.009) at tibialis anterior, average 8.66Hz(P=0.047) at biceps femoris, average 7.53Hz(P=0.016) at erector spinae, and average 7.80Hz(P=0.047) at rectus abdominis. All of the assessments of muscles have shown significant difference statistically. Conclusions: This result has shown that the use of micro current could decrease gait muscle fatigue of flat-footed people. It is recommended to use a microcurrent to reduce their gait muscle fatigue.

High-density lipoprotein (HDL) cholesterol levels are associated with decreased risk of coronary artery disease. Several genome-wide association studies (GWAS) for HDL cholesterol levels have implicated Lipoprotein lipase (LPL) as possibly being causal. Herein, the association between single nucleotide polymorphism (SNP) rs10503669 in the LPL gene and HDL cholesterol levels and triglyceride levels was tested in the Korean population. A total of 994 subjects from Seoul City were included in a replication study with LPL SNP rs10503669. SNP rs10503669 in the LPL gene was associated with mean HDL cholesterol levels (effect per allele 3.13 mg/dL, P<0.0001) and triglyceride levels (effect per allele -18.0 mg/dL, P=0.0026). Subjects with the CA/AA genotype had a 0.42-fold (range 0.23~0.77-fold) lower risk of having abnormal HDL cholesterol levels (<40 mg/dL) than subjects with the CC genotype. When analyzed by gender, the association of LPL was stronger in men than in women. This study clearly demonstrates that genetic variants in LPL influence HDL cholesterol levels and triglyceride levels in Korean adults.

Objectives: The purpose of this study was to analyze correlation thresholds and assessment for salty taste and high-salt dietary behaviors by age. Methods: A total of 524 subjects including 100 each of elementary school students, middle school students, college students, and elderly as well as 124 adults were surveyed for detection and recognition thresholds, salty taste assessments, and high-salt dietary behaviors. Results: Elementary students had a lower detection threshold (p<0.05) and recognition threshold (p<0.01) than did the other groups. Salty taste assessments were lowest among elementary students, followed by middle school students, while college students, adults, and elderly had higher assessment score (p<0.001). Elementary students had significantly lower scores for high-salt dietary behavior than did middle school students, college students, adults and elderly (p<0.001). Middle school students had higher scores for high-salt dietary behavior than did elementary school students and elderly (p<0.001) but no meaningful difference was found in dietary behavior scores between college students, adults, and elderly. There were positive correlations between high-salt dietary behavior and detection thresholds (p<0.001), recognition thresholds (p<0.001), and salty taste assessment (p<0.001). High-salt dietary behavior was more positively correlated with salty taste assessment than detection and recognition thresholds for salty taste. Conclusions: This study suggested that salty taste assessments were positively associated with scores for the detection and recognition thresholds and high-salt dietary behavior.

The purpose of this study is to investigate the misconceptions and the understanding of students on diffusion and osmosis, and to examine the shifts in concept development that result from maturation and additional instruction. In addition, the textbooks were assessed for the sources of the misconceptions. The subjects of this study were 195 students in middle school, 191 students in high school and 195 students in university in Seoul. And the multiple-choice test developed by Odom and Barrow(1995) was used. The results were analyzed by two-way ANOVA in the statistical packages SAS. The major findings of this study are as follows. 1. The mean score of the understanding on the concepts of diffusion and osmosis of junior high school students was 31, that of high school students was 51 and that of university students was 67. In this study, the higher grade students got the higher scores, and it showed significant difference(p<0.01). 2. The mean score of girls was higher than that of boys in all grades. And the difference of the score according to gender showed great difference in high school(p<0.01). 3. An analysis of the patterns of misconceptions about diffusion and osmosis indicated that certain misconceptions prevail across grade levels. 4. An analysis of the contents of textbooks indicated that textbooks may be the source of students' misconceptions about diffusion and osmosis.

In order to normalized the Earth Science Education, experiments and geologic field trainings are very important. But it have not carried out on account of many difficulties in current High School of Korea. These difficulties are lack of time, many problems of the text book, heavy teaching load, shortage of facilities and experimental equipments, and poor quality of teacher etc. The practical training of geologic field trip is very important in Earth Science Education. Finally, wirter propose a new teaching plan of geologic field training as follows: 1. The teacher must prepare the guide paper of field geologic training. 2. Subjects of practical training must simplify. 3. The teacher must take a pre-field investigation in order to get the teaching plan and the preparation of practical field training. 4. Let students observe for themselves on this guide, as if they were geologists. 5. The teacher must conclude about practical training after the working.

The purpose of this study is to examine the concept of Greenhouse Effect as understood by middle school high school university students using a closed-form questionnaire. Based on results of the questionnaire which was administered to 619, the extent to which alternative concepts were held was quantified and compared the difference of various group based on grade level. gender, text and major. Also, subjects were divided into two groups, one is middle school students and the other is high school university students and common themes within conceptual framework of each group were identified by factor analysis. The result showed that students confused Greenhouse Effect with ozone layer depletion in stratosphere and linked familiar contamination around everyday life. acid rain. radioactive contamination, nuclear arsenal to Greenhouse Effect. These trends were more appreciable in female than male, biology major than any other major and text did not make any significant difference. In addition, the result of factor analysis showed that two groups linked familiar contamination around everyday life to Greenhouse Effect and high school university students understand the consequences of an increase in the Greenhouse Effect more systematically than middle school student, perceived the relation between the origin of an increase in the Greenhouse Effect and human activity but confused Greenhouse Effect with ozone layer depletion in stratosphere.

We would like to identify the current status and the problem of the material for sexual education in Korea by analyzing the contents and the subjects of the materials. The 274 materials were collected from 80 institutes from March 1999 to June 1999. The collected ones were analyzed according to title. year of production. producer. subjects of materials and contents. Also, the materials in the internet was searched. Result were summarized by the descriptive statistics with SPSS/PC as followings: Type of materials were video tape (155), books (70), projection slides (43) and CD-ROM (6); Number of production from each institute were 54 from Planned Parenthood Federation of Korea, 39 from Korea Broadcasting System. 23 from Seoul School Health Center. 22 from Seoul Education and Science Research Institute, 16 from Korea Sexual Violence Relief Center, 13 from Republic of Korean National Redcross. and 10 from Korea Educational Development Institute; Subjects of the materials were middle and high school children (55), teachers (35), primary schoolchildren (17) and adult (14), preschool children (5). One hundred forty eight materials did not indicate the specific subjects; Thirty institutes had been providing the information for sexual education and the counseling. According to the above results. we suggest the followings: The systematic development of materials for sexual education appropriate to the specific subjects should be done: Materials in the CD-ROM and internet homepage should be developed more and more; The evaluation tool should be developed and adapted to the materials for the recommendation of the good materials; Database of the sexual materials should be provided for further development, evaluation and utilization.
