This study investigated elementary school students' perception, preferences, and intake of Korean traditional foods, focusing specifically on kimchi, tteok (rice cake), and eumcheong (beverage) varieties; and compared them by gender, living with grandparents, mother's occupation, and meal preparation by the grandmother. The subjects were 287 6th grade elementary school students in Busan. The results were as follows: 80% of children were interested in Korean traditional foods. 40% believed that their intake of Korean traditional foods was decreasing because these foods were not palatable to them. The majority of them, however, said they would continue to eat Korean traditional foods as they had done (54.7%) or eat more than before (36.6%) in the future. The children thought that Korean traditional foods were rich in nutrition and good for their health. The children had the highest preference for Baechu-kimchi among varieties of kimchi, and they had high preferences for Songpyeon, Galaitteok, and Injulmi. They had high preferences for Sikhye, citron tea, and adlai tea. Over 80% reported consuming Baechu-kimchi and Kkakdugi three to four times per week. They had eaten Injulmi the most frequently among the tteoks, while over 80% had eaten the other types of tteok only once or twice per month. Adlai tea, citron tea, and Sikhye were drunk more than once per week. In general, we noted no significant differences in the children's perceptions, preferences, and intake of Korean traditional foods by gender, living with grandparents, mother's occupation, and meal preparation by grandmother, with the exception of several items. The students had a very positive perception of Korean traditional foods. They had higher preferences for and had more frequently consumed the more familiar Korean traditional foods. It is therefore suggested that if the children had opportunities to experience Korean traditional foods more frequently and variously at home or in restaurants, they would appreciate Korean traditional foods even more, and develop higher preferences for these foods.

This study was to investigate utilization status of internet, health/nutrition websites among children, and to assess the needs for developing nutrition websites and education programs for children. The survey questionnaire was administered to 5-6th grade students (n=434) at two elementary schools. About 32% used the internet every day while 19.5% used it whenever they needed, showing significant differences in internet usage by gender (p<0.01). Although the subjects used the internet frequently, those who used health/nutrition websites were 23.3%. The purpose of using these sites were mainly 'to obtain health/nutrition information' (55%), 'to get information regarding weight control' (17%). Fifty-six percent of the users were satisfied with the nutrition websites, but only 30% said that they were helpful. The preferred topics in developing nutrition websites were assessment of obesity, exercise methods, weight control methods, nutrition information (e.g., diet for stature growth), dietary assessment and food hygiene. Girls showed more interest in these topics than boys (p<0.05). For school nutrition education, girls showed more interest than boys in topics for cooking snacks (p<0.001) and selecting snacks (p<0.05). In nutrition websites, subjects wanted to have information and game/quiz, as well as getting information using Flash animation. The favorite colors for screen and text were slightly different by gender (p<0.01). In school nutrition education, 89.5% of subjects liked to have activities (e.g., cooking, exercise, game). They also liked materials using computers, video and internet than printed materials. If nutrition education was done at schools, subjects wanted to receive 5.7 times of education per semester on average (mean length: 42.6 min/session). This study suggests that nutrition websites and education programs for children should include the topics such as assessment of obesity or diet, weight control and special information (e.g., diet for growth) as well as general information. In designing nutrition websites and programs, methods including game, quiz, Flash animation and activities (cooking, exercise) could be appropriately used to induce the interest and involvement of children.

The purpose of this study is to examine children's/adolescents' motives for playing internet games and adaptation to school in accordance with their frequency levels of playing internet games. Participants were 236 children from grades 4, 5, and 6 in two elementary schools and 237 adolescents from grades 1, 2, and 3 in one middle school. They were measured on frequency levels of playing internet games, motives for playing internet games, and adaptation to school. Collected data were analyzed by SPSS WIN 12.0 for reliability, frequency, Chi-square test, t-test, Pearson's correlation, and one way ANOVA. Major findings of the research are as follows: First, children's/adolescents' frequency levels of playing internet games differed by their gender. The male ratio was much higher than the female ratio in the potential risk group and the high risk poop. In contrast, no grade differences on the frequency levels of playing internet games were found. Second, children's/adolescents' motives for playing internet games differed by their gender. Especially, among the motives the greatest difference between male and female was marked for 'Social Relationship'. Third, children's/adolescents' motives for playing internet games differed by their frequency levels of playing internet games. For 'Conformity,' the low risk group differed from the high risk group. For 'Spending Time', 'Benefit', 'Competition', and 'Social Relationship', the low risk group differed from the potential risk group and also from the high risk poop. Fourth, children's/adolescents' adaptation to school differed by their frequency levels of playing internet games. The high risk group exhibited a low level of adaptation in 'Academic Activities', 'a subcategory of adaptation to school.

Background: Although more than two third of colorectal cancers are localized on the left side, recent studies suggest a right ward shift in anatomical distribution with increase in proximal colon cancers. The aim of the present study was to determine the anatomical distribution of colorectal cancer in a referral center over a 15 year period. Method: Records of patients who underwent colectomy in the Cancer Institute of Iran from 1994 to 2009 were retrieved. Data including anatomical localization, year of diagnosis, patient age and gender, tumor histology and differentiation, and disease stage were extracted. Tumors located from the cecum to the distal transverse colon were classified as right side and those occurring from the splenic flexure to the descending colon as left-sided. Cancer of rectum and recto-sigmoid junction were considered as rectal cancers. Results: A total of 442 patients including 220 (49/8%) men and 222 (50/2%) women with mean age 53 were included. Most patients were in stage II &III (47.1% and 33% respectively). There were 157 (35.5 %) colon cancers and 285 (64.5%) rectal cancers. 43.3% of the colon cancers were right sided and 56.7% were left sided. There was no statistically significant increase in right sided cancer during the period of the study. There were no significant differences in age at diagnosis, gender, grade and stage of tumor between the right and the left sided cancers. Conclusion: No proximal shift over time was identified in our study.

The purpose of this study is to find out the level of science teaching efficacy belief in the elementary school teachers and to find out the students' science process skills and scientific attitudes according to the level of the teacher's science teaching efficacy belief. After measuring science teaching efficacy belief of 109 teachers from nine elementary schools, three teachers who received the high score and three teachers who received the low score were selected from each 5th and 6th grade. Science process skills and scientific attitudes of 331 students who were in the selected 12 teachers' classes were measured. The results of this study were as follows; First, there were significant differences on the elementary school teachers' science teaching efficacy belief according to teacher's gender and career. The men's average score was clearly higher than women's average score on personal science teaching efficacy in science teaching efficacy belief according to teacher's gender. There was a obvious difference between the group of more than six-year less than ten-year and the group of more than fifteen-year less than twenty-year, the group of more than twenty-year on science teaching outcome expectancy in science teaching efficacy belief according to teacher's career. Second, there was not a evident difference on the elementary school students' science process skill according to the level of the elementary school teachers' science teaching efficacy. Third, there was a distinct difference on the elementary school students' scientific attitude according to the elementary school teachers' science teaching efficacy. There was a significant difference on the openness and the endurance in each scientific attitude. The level of science teaching efficacy belief in the elementary school teachers had few effects on the elementary school students' science process skill, on the other hand the level of science teaching efficacy belief in the elementary school teachers had an positive effect on the elementary school students' scientific attitude.

Objective: The current study aimedto screen for possible factors which affect prognosis of chondrosarcoma. Methods: Thirty seven cases were selected and analyzed statistically. The patients received surgical treatment at our hospital between December 2005 and March 2008. All of them had complete follow-up data. The survival rates were calculated by univariate analysis using the Kaplan-Meier method and tested by Log-rank. ${\chi}^2$ or Fisher exact tests were carried out for the numeration data. The significant indexes after univariate analysis were then analyzed by multivariate analysis using COX regression model. Based on the literature, factors of gender, age, disease course, tumor location, Enneking grades, surgical approaches, distant metastasis and local recurrence were examined. Results: Univariate analysis showed that there were significant differences in Enneking grades, surgical approaches and distant metastasis related to the patients' 3-year survival rate after surgery (P<0.001). No significant difference was not found in gender, age, disease course, tumor location or local recurrence (P>0.05). Multivariate analysis showed that Enneking grade (P=0.007) and surgical approaches (P=0.010) were independent factors affecting the prognosis of chondrosarcoma, but distant metastasis was not (P=0.942). Conclusion: Enneking grades, surgical approaches and distant metastasis are risk factors for prognosis of chondrosarcoma, among which the former two are independent factors.

이 연구에서는 끓는점 학습에서 인지 갈등, 상태 흥미, 개념 변화 사이의 관계를 조사했다. 또한, 이들 관계에서 성에 따른 차이도 조사했다. 중학교 1학년 학생 370명이 본 연구에 참여했다. 먼저, 학습된 오개념을 지닌 학생을 선별하기 위해 선개념 검사를 실시했다. 변칙 사례를 제시한 후, 변칙 사례에 대한 반응 검사와 상태 흥미 검사를 실시했다. CAI 프로그램으로 수업 처치를 한 후, 직후 개념 검사를 실시했다. 4주 후에 동일한 검사지로 개념 파지 검사를 실시했다. 인지 갈등과 상태 흥미 검사 점수는 모두 직후 개념 검사 및 개념 파지 검사 점수와 유의미한 상관이 있었다. 중다 회귀 분석 결과, 상태 흥미가 인지 갈등 보다 개념 변화 및 개념 파지 정도를 예측하는데 있어 더 중요한 것으로 나타났다. 남학생의 경우에는 상태 흥미만이 개념 변화 및 개념 파지에 대해 유의미한 예측 변인으로 나타났으나, 여학생의 경우에는 인지 갈등만이 유의미한 예측 변인으로 나타났다.
