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.

The purpose of this study was to investigate the effect of alcoholic drinking on the dietary habits among university students. The data was collected from 355 students (male : 188, female : 167) living in Busan. The questionnaire composed of general information, person with the lunch meal time, skipping meal, meal type place overeating, snacking eating out, food intake pattern. For statistics analysis, SPSSWIN 12.0 was used. The results were summarized as follows. First, the rates of alcohol drinking in male and female students were 94.1% and 93.4% respectively and the rate of under 19 years old's drinking were 94.4%. Second, in the appearance of drinking, the difference in dietary habits wasn't shown to be significant. However in term of dinner, few female students sometimes haven't dinner (p<0.01). And female group showed frequently eating out (p<0.05) and overeating more than male group(p<0.001). Third, the alcohol drinking group and non-alcohol drinking group showed significantly similar consumption frequency of cereal, meat products, fruits vegetable, oil sugars. But the intakes of milk and dairy products in male students were significantly higher than in female students (p<0.001). These results indicated that more attention should be taken to university students, having habits of skipping meal, alcohol drinking and low intake for nutrition knowledge or attitude so as to improve their health.

Along with the increasing interests of modem-day society toward topics of health and beauty, various studies are being actively conducted on the effects of diet for obesity prevention, and separate from aspects of disease prevention and health promotion. This study aimed to examine individual perceptions of obesity by age, and to prepare basic data for implementing an age-based weight control system, by comparing attitudes toward weight control. The research and analysis were conducted using questionnaires, provided to high school students(teenagers, 189 students), college students(20 or older, 116 students), and adults(30 or over, 88 adults) living in Daegu City. In terms of the respondents' perceptions of obesity, among those who described themselves as overweight, only about 10% were actually proven to be overweight. Also, significantly more female students than male students perceived themselves as overweight, despite the fact that they were in a normal weight range(p<0.007). There was no significant difference in the cause of obesity by gender, but it was found to be attributed to a lack of exercise for teenagers, and poor eating habits for those in their twenties and thirties. Concerning the intention to participate in a weight management class, the female teenagers showed significantly more interest than the male teenagers(p<0.017). Also, with regard to the respondents' attitudes toward weight control, the teenage females showed significantly higher interest in weight control than the teenage males p<0.003 and those in their twenties p<0.001. Moreover, regarding the period in which the respondents became most interested in weight, the teenage male students were most interested in weight during their middle school years and teenage females became most interested during their high school years. Therefore, the information from this study leads us to propose there is a need to correct the suggested reckless dieting that is occurring within an appearance-based society, as well as a need to establish a systematic weight control system, along with gathering subsequent basic data.

Until now it has not surely been pointed out about the relation between the biting force and the facial types in scientific view. But it's correlation was assumed by several scientists : recently some literatures reported about the maximum biting force and facial types, but there's only a little articles about the relation between the biting force(biting force contain maximum biting force, chewing force and swallowing force) and facial type. So this study was, firstly, performed to establish the relation of the nomal face and long face versus biting force. 2ndly it was performed to establish the relation between the difference in mouth opening degrees versus biting force. 3rdly it was performed to establish the relation between male and female versus biting force. Biting force was measured from 56 adults (normal 26, long 30) whose samples was selected from Yonsei university students and Hospital patients. Sample was divided into 2groups (normal and long) by lateral cephalogram. The results of this study was obtained as follows. 1. Maximum biting force and chewing force in long face was smaller than normal face. 2. When the thickness of transducer was changed from 6m to 9mm, maximum biting force andchewingforcewaslargerthanbefore. 3. In case of comparing with male and female, male was larger than female in maximum biting force and chewing force.

Purpose: This study is executed to examine the effects of Korean somatotype on energy consumption and hormone changes during treadmill gait. Methods: The objects of study were a total of 70 university students in their 20s and 30s divided into 7 groups according to somatotype with 10 members each, 4 groups of male (M1, M2, M3, M4) and 3 groups of female (F1, F2, F3). Results: In case of male groups, there was a significant difference in VO2 and VCO2 between group M1, M2 and M3 (p<0.05). There was also a meaningful difference between Phase1 and Phase2, Phase3 and Phase4 in a phase (p<0.01). In case of female groups, there was a meaningful difference in VO2 between F1 and F2, F3 (p<0.01). There was also a significant difference between Phase1 and Phase2, Phase3 and Phase4 in a phase (p<0.01). There was no significant difference in VCO2 among them, but there was a significant difference in it between Phase1 and Phase2, Phase3 and Phase4 (p<0.01). There was equally no significant difference in the concentration of adrenaline and nor-adrenaline among both male and female groups, but such concentration showed meaningful difference before and after exercise (p<0.01). Conclusion: Energy consumption differs according to somatotype. There is a difference in hormone change, indicating that somatotype has effects on the physiological change. Therefore, in future exercise should be executed in more diverse conditions to further study somatotype with energy consumption and the correlations of hormone change.

This study investigated changes in salivary cortisol, lactic acid, and heart rate along the route during walking exercise in a forest environment for the purpose of reducing stress. Walking exercise in a forest environment was conducted on a Hill Type (Distance: 800m, Average slope 25°, Altitude 112m) and Step Type (Distance: 800m, Average slope 25°, Altitude 114m) routes for 10 female college students in their 20s. The subjects were asked to walk at a speed of 60 bpm. The resulting changes in salivary cortisol, lactate, and average heart rate during exercise were compared and analyzed using Repeated Measurement two-way ANOVA, and the maximum heart rate during exercise and average heart rate at rest were compared and analyzed using paired t-test, and the following results were obtained. First, there was no significant difference in salivary cortisol depending on the type and period of the forest, but it tended to gradually decrease. Second, there was a significant difference in lactic acid depending on the type and period, and it was higher in Step Type. Third, there was a significant difference in the average heart rate during exercise, and it was higher in Step Type. Fourth, there was a significant difference in maximum heart rate during exercise, and it was higher in Step Type. Fifth, there was no significant difference in average heart rate during rest. In summary, walking exercise in a forest environment can be effective for stress reduction for female college students in their 20s, but it appears that forest routes should be selected according to physical strength level, and walking exercise in a forest environment for long periods of time is not recommended. For this purpose, it is suggested that it is appropriate to select the Hill Type route.
