The purpose of this study was to compare clothing attitude and clothing purchase behavior of two age groups of adult men,- college students and middle aged. Four aspects of clothing attitude (fashion interest, status symbol, conformity, practicality/comfort) were assessed with 20 Likert type questionnaires adapted from the previous researches. Four aspects of purchase behavior(information sources used, store patronage, importance of store attributes, clothing selection creteria for occasions) were measured with forced choice questionnaire developed or adapted from previous researches. The questionnaire were administrated to 512 male college students and middle aged men. The data were analysed using frequency, percentage, and t-test. The major findings drawn from this study were as follows : 1. Clothing comfort among four aspects of clothing attitude according to the age group was that middle-aged men showed higher conformity than college students. 2. For the information source for apparel purchase, college students used consumer dominated information source while middle-aged men used market dominated information source. 3. For apparel purchase, students preferred brand franchise store, and factory outlet/off-price store, while middle-aged preferred department store and custom-made. Among six store attributes, convenience and price were the most important attributes to the students, while convenience and high quality to the middle aged. 4. The most important clothing selection creteria for formal occasion (job interview, wedding ceremony) was dignity. Comfort/practicality were important creteria for both of leisure occasion and daily attendance (office, school).

Objectives : The aim of this study is to examine the effects of SSP(silver-spike point) therapy, applied to acupuncture points, on the middle cerebral arteries blood flows of sample group(tention-type headache patients, n=12) and control group(non tension-type headache patients, n=12), and on the reduction of their headaches, when applied to acupuncture points. Methods : We stimulated 6 acupuncture points for headache with the SSP(three times a week for three weeks), and measured VAS(visual analogue scale) and the blood flow of the middle cerebral arteries with TCD(transcranial doppler ultrasonography). Results : The blood flow of the middle cerebral artery and VAS of the sample group and the control group were compared four times(initial, 1weeks, 2weeks, 3weeks) and significant differences in the measurements were found at 3 weeks(p<.05). The blood flow of the middle cerebral artery of the sample group was significantly increased, and VAS was significantly decreased in both groups. Conclusions : The silver-spike-point low-frequency electrical-stimulation treatment, applied to acupuncture points, can significantly increase the blood flow of the middle cerebral arteries in headache patients and can thus alleviate their headaches.

A study was conducted to compare urinary Ca excretion and factors influencing urinary Ca excretion in 30 young and 62 middle-aged Korean women. Mean daily intake levels of total protein and P were significantly higher in middle-aged women but Ca and animal protein intake levels of the two groups were similar. The average percentage of daily Ca intake from milk and milk products in young women was 45% while in middle-aged women it was about 24% The frequency of milk consumption was inversely correlated with blood pressures of the subjects. Mean 24-hour urinary calcium excretion in young and middle-aged women were 163.7mg and 174.9mg respectively. The difference was not significant. Menopause of the mid-dle-aged women did not affect urinary calcium levels. However the proportion of subjects with more than 250mg of Ca in 24-hour urine tended to be higher in middle-aged group Factors significnatly correlated with urinary Ca excretion of subjects were systolic and diastolic The study verifies the need for more systematic studies on Ca requirements and the interrelation-ship among Ca and na metabolism blood pressures and bone loss in the middle-aged Korean.

One of major factors for learning achievement is the student's learning preference according to his character type. In course of learning, if a student studies e-learning contents opposed to his preference, then he would be under stress and his blood pressure and heart beat be changed. For measuring unwillingness, we used spectral components in frequency domain known as stress measure. For 13 children attending kindergarten we examined S(sensing)/ N(intuition) of MBTI and presented same learning contents during 10 minutes. During learning we gathered ECG signals, changed into HRV(heart rate variability), transformed time-varying HRV signal into spectral density in frequency domain. And then, we divided it into three areas of low(LF), middle(MF), and high-frequency(HF) and calculated stress measures by rates of those frequency area. We compared estimated stress measures of S group with them of N group whether students in different group preferred different contents or not. Experimental shows that students according to MBTI type prefer different contents.

The objective of this study was to investigate the consumption pattern of snacks-containing trans-fatty acid in adolescents living in the Kwang-ju area of Korea, and to analyze the relevance toward their eating behaviors, body composition, nutrient intakes, and consumption frequency of snacks-containing trans fatty acid. A survey questionnaire was developed in order to investigate general environmental factors, eating behavior, nutritional knowledge, and the consumption frequency of snacks-containing trans fatty acid. A total of 312 middle school students were surveyed. The collection rate was 97% and ultimately 282 cases were analyzed. Anthropometric measurements, body composition data, and nutrient intakes were also collected. The consumption frequencies for snacks-containing trans-fatty acid were negatively correlated with food behavior scores (p<0.01) however, pocket money and snack intake frequency per day were positively correlated with consumption frequency. Also, snack consumption frequency had some correlation with the subjects' anthropometric measurements and body composition data such as total body water (p<0.01), body protein (p<0.01), body minerals (p<0.01), and skeletal muscle mass (p<0.01). Finally, the consumption frequency of snacks-containing trans fatty acid was significantly correlated with calcium intake (p<0.05), it also showed correlations with vitamin A, retinol, ${\beta}-carotene$, and folic acid intake, although statistical significance was not verified.

Objectives: The rapidly changing dietary environment requires a study that addresses the status of middle and high school students regarding their consumption of convenience food sold at convenience stores. Methods: This study examined adolescents' lifestyle patterns, dietary habits, and status of consuming convenience food at convenience stores. A total of 659 students (329 middle school students and 330 high school students) in Incheon participated in this questionnaire survey. Results: The mean age of the subjects was 13.7 years for the middle school students, and 16.6 years for the high school students. The gender and grade distributions in the middle and high school students were similar. The middle school students reported that they spent more time using electronic devices (p<0.001) or watching TV (p<0.001) than high school students. More than 60% of middle and high school students consumed convenience food at convenience stores without statistical difference between the two groups. The main reason for consuming convenience food from convenience stores was its convenience followed by taste in both groups. Despite the high frequency of consuming convenience food, the students rarely checked the nutrition labels at the time of purchase. On the other hand, they were still most concerned about the nutritional value of the convenience foods when they consumed convenience foods. The most frequently consumed convenience food was ramyon in both groups. Significant positive correlations were observed between the frequency of consuming convenience food at convenience stores and lifestyle factors for the middle school students, including monthly allowance, time for using electronic devices, and number of private lessons. For the high school students, however, the only monthly allowance had a significant positive correlation with the consumption. Conclusions: Adolescents are increasingly exposed to convenience foods and relevant nutritional issues are a concern. Therefore, a dietary environment that is adequately formed for the healthy development of youth as well as systematic nutrient education that is appropriately designed for both middle and high school students is required.

Objectives : The purpose of this study was to examine the oral health behavior and knowledge of middle schoolers in an attempt to facilitate the selection of what to teach about oral health. Methods : The subjects in this study were 315 students at three different middle schools located in the city of Gunsan. After a self-administered survey was conducted by using structured questionnaires in collaboration with their homeroom teachers, the answer sheets from 315 students were gathered. And the answer sheets from 302 students were analyzed with SPSS 12.0 program except 13 incomplete ones. The findings of the study were as follows: Results : 1. By gender and grade, the middle school boys(51.3%) outnumbered the middle school girls(48.7%), and the seventh, eighty and ninth graders respectively accounted for 31.5, 32.8 and 35.8 percent. 2. As to the parts of the mouth they brushed, the largest number of the seventh graders(31.6%) and ninth graders(56.5%) brushed their teeth and tongue. The largest group of the eighth graders(39.4%) brushed their teeth, tongue and gums, and the gaps between them and the others were statistically significant. 3. In regard to toothbrushing frequency, the ninth graders did that 2.62 times, which was the largest frequency, but the gap between them and the others was not statistically significant. 4. Concerning school oral health education experiences, the rates of the seventh, eighth and ninth graders who had ever received that education stood at 69.5, 50.6 and 50.5 percent respectively, and those students significantly outnumbered the others who hadn't(p<0.01). 5. As for the relationship of their oral health behavior scores to toothbrushing frequency, there was a statistically significant correlation between the two(r=0.227, p<0.001). And the oral health knowledge scores had a statistically significant correlation to toothbrushing frequency (r=0.116, p<0.05) and oral health behavior scores(r=0.358, p<0.001). Conclusions : It is concluded that proactive oral health education must be made through diverse programs and systems. Also, regular oral examination and active oral health program for preventing dental caries and periodontal disease should be proliferated in order to evaluate achievement and effectiveness and maintain oral health care.

The purpose of this study was to investigate fast-food consumption and it's nutrient density, and the correlation between subject's characteristics and consumption frequency of fast-foods among middle school students. The questionnaires were distributed to 150 male and 190 female students in Cheongju city. The data were analyzed using SAS and statistics used were percent of frequency, $X^2$-test, t-test, and pearson's correlation coefficient. The main reasons for using fast-food restaurants were 'good taste' and 'convenience'. The major concerns when the subjects choose fast-foods were 'taste ($65.9\%$), price ($20.3\%$) and 'nutrition'($6.0\%$). The consumption pattern of fast-foods go as follows: twice a month ($42.3\%$), once a week ($31.5\%$), and less than once a week. The number of fast food items that the subjects ate for one meal was two ($46.0\%$) or three ($33.2\%$). The most frequently chosen combination of foods for number of two choices was beefburger and cola. The mean average energy intake from fast foods for one meal was 620.7 kcal for male, 504.5 kcal for female. The energy ratio of carbohydrate : protein fat from fast foods was 49 : 14 : 43, which means fat intake is much higher than recommended level ($20\%$). Fiber was appeared to be the lowest on the nutrient density which was $17.7\%$ of the recommended level for Koreans, vitamin C was next ($22.8\%$ for male, $20.1\%$ for female). In mineral, iron was the lowest ($71.8\%$ for male, $67.1\%$ for female), and protein was over $100\%$ for both males and females. Frequency of fast food intake was positively correlated with eating frequency of the salty, the sweets, him, caffeine containing foods, instant noodles, and cookies. In conclusion, frequent consumption of fast foods can lead unbalanced nutrient intakes for middle school students, and those who consumed fast foods frequently showed undesirable food habits in their daily meal. Therefore, nutrition education for middle school students should be needed to encourage them to choose more nutritious food and have healthier dietary pattern.
