The purpose of this study was to investigate the primary school students' and their mothers' vegetables preferences. Total of 360 students and their 360 mothers in Seoul and Gumi-si were participated in survey during July, 2011, and data of 253 students and their 253 mothers(70.3%) were analyzed by SPSS ver 12.0. The preference scores of mothers were higher than those of students in all kinds of vegetables examined, except bean sprout and laver. The preference scores of lower grader(2, 3 grade) were higher than higher graders(5, 6 grade), and those of female student were higher than male students. The preference accordance degree of students and their mothers were highest in seaweeds group, and lowest in root stalk vegetables. The onion, welsh onion, water dropwart, mustard kimchi were showed specially low student-mother preference accordance. Among the 50 vegetables investigated, all mother had chance to eat was 31 vegetables, and all students had chance to eat was 10 vegetables. The 3 kinds of seaweeds such as seastaghorn, ceylon moss and seaweed fusiforme were the foods that more than half of student had no experience to taste. Environmental variables, such as having the sibling, whether or not mother had job, the type of breakfast foods, and food and frequency of eating-out, all had no significant influences on vegetables preferences.

This study was conducted to examine the effect of family environment on smoking behavior, smoking knowledge and smoking attitude in primary school students. For the purpose of the study, a questionnaire-based examination was made with 1,476 sixth-grade students in Taegu from November 1st to 30th, 1998. The results of the study are summarized as follows. Out of 22 points for smoking knowledge, the male student group got 12.9 points, and the female student group 13.0 points. For both groups, students with better school achievement showed a significantly higher score (p<0.01). For the female student group, those who had nonsmoking fathers showed a significantly higher score(p<0.05). A perfect score for smoking attitude was 20 points. The male student group received 14.9 points and the female student group 16.3. For both groups, the score appeared to be significantly higher in the students who had better school achievement and no smoking experience. For the female group, the score was higher if they were living with widowed mothers or had nonsmoking parents. The percentage of smoking experience was 22.0% for the male group and 4.7% for the female group. The present smoking percentage of both groups accounted for 0.3% and 0.1%, respectively. The percentage of the male group's smoking experience was significantly higher if school achievement was poor, if the mother has religious, and if her occupation belonged to significantly different category. For the female group, it was significantly higher if a mother's educational background was less than the primary school level, or if a mother smokes. Family adaptability and cohesion were not significant variables for both groups. The score for smoking knowledge according to family cohesion was highest if male and female members were in an enmeshed state. For the female group, the higher the family adaptability, the significantly higher the score for smoking knowledge. The score for smoking attitude according to family cohesion showed a significant difference for both groups. The family adaptability was not a significant variable for both groups. The results of multiple regression analysis, with the scores for smoking knowledge and smoking attitude were used as a dependent variable, revealed that, for both groups, the better the school achievement. For the female group, the higher the family cohesion, the significantly higher the score(p<0.01). For the male group, the score for smoking attitude was significant1y higher if school achievement was better, if students were living with a widowed mother or father, if they had drinking mothers, if family adaptability was low, if family cohesion was high, or if the score for smoking knowledge was high. For the female group, the score for smoking attitude was higher if school achievement was better. Also, if famale student had nonsmoking fathers, if the family adaptability was lower, on the higher the score for smoking knowledge, a smoking attitude scored higher. The results of a multiple logistic analysis, with smoking experience as a dependent variable, revealed that, for the male student group, the worse the school achievement, the higher the score for smoking knowledge, the lower the score for smoking attitude, or the lower the family adaptability, the higher the percentage of smoking experience. For the female student group, the higher the score for smoking knowledge or the lower the score for smoking attitude, the higher the percentage of smoking experience. In conclusion, family environment, including smoking of parents and family functions, had a great effect on smoking knowledge, smoking attitude and smoking experience of students, and it is required to adjust subjects and methods for smoking and nonsmoking education as smoking attitude and smoking behavior greatly differ according to sex.

Oral health knowledge, awareness and attitude towards parents of the dental hygiene students is giving a mutual influence over their children enrolled in the dental hygiene department. Therefore, the university is a situation that requires students to oral health education that can be caused by changes in attitudes and behavior, rather than a simple knowledge transfer. This study was performed to compare the differences in oral health knowledge and awareness of dental hygiene department parents. Research method was used to survey the SPSS v19.0 through the Google study has used a total of 200 in the final analysis to the National Dental Hygiene Department of the lower grades (first grade) and seniors (fourth grade), the student's parent. The results child's impact as a student in the dental hygiene department is older group were more statistically significant than the younger group. Oral Health Knowledge average of the parents of the grade your child is younger parents, older parents, cognitive average younger parents, older parents, education, whether through a child younger parents older parents, the impact is younger parents was higher in the upper grades to both parents of older parents. Therefore, the older the child the more it can be seen that grade their knowledge and habitual behavior affects the oral health knowledge and awareness of their parents.

The purpose of this study is to investigate student's Acquisition about the conception of the Earth Rotation between difference of their Spatial Sensibility. In this study, four students were selected out of 83 9th graders in Gwangju, Korea. The spatial sensibility test instrument was developed by the Korean Testing Center, and the test instruments of 'the movement of celestial bodies' were developed by Kim (1997). The results were as follows: Students with higher spatial sensibility understood precisely about the Earth's rotation in stereoscopic space. However, those with lower spatial sensibility failed to grasp the Earth's rotation and memorized it as fragmentary concepts. As for gender effect, male student with higher spatial sensibility explained the concepts clearly, while that with lower spatial sensibility has difficulty with the Earth's rotation in relation to the diurnal motion of celestial bodies. On the other hand, female student with higher spatial sensibility explained the concepts correctly in detail, while that with lower spatial sensibility had difficulty explaining the concepts in stereoscopic space. Therefore, students with higher spatial sensibility should be presented with problems in which they form their own solution. Those with lower spatial sensibility should be allowed to understand the phenomena intuitively. In developing teaching methods, female students should interact with the concepts in stereoscopic space directly, while male students should consider the celestial objects from various viewpoints. Then spatial sensibility in relation to the movement of celestial bodies would be expected to improve.

This study examines room assignments to improve accessibility in a university dormitory depending on the student grade, taking into account frequency of using a certain common space. An integer programming model is presented to minimize the total moving distance from the common space to the students' rooms for accessibility. The model also constrains the maximum capacity of a room, and disallows different grade students to be assigned to the same room. This model is similar to a facility location problem used widely in the supply chain management field. Applying our optimization model to a small group at the dormitory of Unversity A as the case study, our results indicate that lower grade students are assigned rooms closer to the common space due to their higher frequency of using that space to guarantee high accessibility. Moreover, if higher grade students are prioritized to select their rooms, we suggest an objective function that imposes a penalty in cases when lower grade students select rooms with priority. Based on the results obtained, we propose assigning rooms to students in a dormitory by considering their complex requirements and convenience to use the common space.

The present study was conducted as a pilot investigation to suggest the standards of acoustic performance for classrooms suitable for incomplete hearing people such as children under 9 years of age. Subjective evaluations such as questionnaire and speech intelligibility test were conducted to 264 students at two elementary schools in Cheong-ju in order to analyze the characteristics of the listening environment in the classrooms of the lower grades in elementary school. The survey was undertaken with a total of 264 students at two elementary schools in Cheong-ju, and investigated their satisfaction with the classroom listening environment. As a result, students responded that the most helpful information type for understanding class content is the voice of teacher. In addition, the volume of the current teacher's voice is normal, and the level of clarity is highly satisfactory. As for the acoustic performance of the classroom, the opinion that the noise was normal and the reverberation was very short was found to be dominant in overall satisfaction with the listening environment. Meanwhile, as a result of speech intelligibility test using the word list selected for the lower grade students of elementary school, it could be inferred that the longitudinal axis distance from the sound source in the case of 8-year-olds is a factor that affects speech recognition.

This study investigates the effect of GIS-integrated lessons on spatial thinking abilities and geographical skills using discourse analysis along with a comparative three-case case study method. A series of curricula were designed and implemented in an 8th grade classroom for a semester. The data collected consist of the dialogue transcripts of six consecutive GIS-integrated lessons. The transcripts were analyzed to identify the moves (speech acts) used by each student and to classify discourse content of spatial thinking and geographical skills. Based on three individual case studies, a cross-case study was performed to uncover any relationship between the phenomenon and the contexts. The empirical evidence from discourse analysis demonstrated that students were able to generate appropriate terms representative of spatial thinking and geographical skills although students appeared to possess primarily lower-order spatial abilities, followed by a moderate-level of spatial abilities. Considering that the unit was implemented in a biology class rather than a geography class the result reflected the fact that the student's spatial thinking and geographical skills were attributable to the GIS-integrated lessons. Thus, the results have a great implication for GIS-integrated lessons and geography education as an innovative tool for improving student's spatial thinking and geographical skills.

This study was conducted with 512 students in 4 primary schools located at the inner and the outskirt of K city, Northern Kyungsang Province from November 6, 2001 to November 27, 2001(during 3 weeks). This study was a research about the difference of a bullying degree and tendency of both teasing and teased students. The purpose of the study was to help nursing teachers in charge of student consultation and treatment. The findings are as follows: First, for to whom students confess their worries, students in lower grade talked to their parents while students in higher grade talked to their close friends. The higher grader, the higher rate in solving their problems by themselves. For how many students are teased by their peers in groups, 52.0％ students answered 1 or 2 students in a class. For the reasons of bully, 37.0％ higher graders answered, very selfish and putting on airs after 29.6％ lower graders answered, ugly and bad at speaking. Second, for perception of peer relation, 81.3％ students participating in the study answered, very important. For a question whether students satisfy present relation with their friends by gender, 53.7％ boys were satisfied while 34.6％ girls were satisfied. Third, for difference in bullying by gender, boys mainly teased others by using words and physical power(p<0.000) while girls estranged others. When it goes to teased students, it was the case: boys were bullied physically(p<0.000) and linguistically while girls were hurt by estrangement. Having nothing direct to do with school achievement, nursing teacher should make good use of such an advantage that students tend to easily confess their worries to them and take care of psychological aspects of students in treatment. Furthermore, it needs to include contents of bully in the regular heath care education.

Purpose: The aim of this study was to investigate the effects of academic stress and self-control ability on temporomandibular disorder (TMD) of adolescents. Methods: Participants were 1,112 teenagers who were 1st grade students of middle and high school. After checking their academic stress and self-control ability through a self-administrated questionnaire, the students were examined their TMD by two trained dentists. We drew a comparison the level of their academic stress and self-control ability between the students with and without TMD. We divided them to four groups according to the level of academic stress and self-control. And we checked prevalence of TMD in each level. Results: The group of students with TMD was higher academic stress score level than the students without TMD (p<0.05). And they had lower self-control score level than the students without TMD (p<0.05). Even if they were under the same academic stress, the group of students with higher self-control score was less TMD prevalence than the students with lower score. Conclusions: Academic stress makes adolescents to increase TMD and high ability of self-control makes them to decrease it. And these tendencies are seemed to have a great influence on young male student.

The purpose of this study is to analyze elementary school students' personality, scientific attitude and to find the correlation between elementary school students' personality and scientific attitude. To determine this, the distribution of sixth graders' personality and scientific attitude was examined and correlation between the lower categories of each one was analyzed. The test tools and the subject were decided through the two preliminary examination, personality test and scientific attitude test were investigated appling to a total of 354 sixth-grade students at eight elementary schools in this study. The test results were analyzed with averages, standard deviations, correlations, ANOVA using SPSS/PC/sup +/. The major results of analysis are as follows. First, the distribution of scientific attitude proved that the average of boys' curiosity was higher than that of girls' curiosity, but girls' average was higher than boys' average in criticalness property, cooperation property, preparation property, continuation property and patience property. The distribution of upper group and lower group in personality properties revealed that the ratio of upper group was higher than that of lower group in activity property, social property, but the ratio of lower group was higher than that of upper group in responsibility and reflective property. Second, the socio-populational variables affecting 6th graders' personality' and science attitude were a sex, a sibling order. The cognition variables affecting 6th graders' personality and science attitude were preference, extent of usability to practical life and interest of science. Third, analyzing the correlation between lower categories of personality and lower categories of science attitude revealed that activity property of personality rather highly correlated to willingness property, critical property at .399(p<.01), .351(p<.01) respectively. and that consideration property of personality highly correlated to curiosity, critical property at .451 (p<.01), .415(p<.01) respectively.
