Objectives: Adulterated food education in adolescence period is very important because dietary management related to food safety is not made in a short period. This study aimed to identify dietary lifestyle factors which drive adulterated food management among middle and high school students. Methods: Data was collected from 270 middle and high school students in Daegu using a self-administered questionnaire in March and April of 2015. Data was analyzed using frequency analysis, one-way analysis of variance, ${\chi}^2$-test, factor analysis, reliability analysis, regression analysis, and cluster analysis. Results: The results of factor analysis indicated that adulterated food management awareness was classified into necessity, difficulty, and food purchasing anxiety. The adulterated food management capability was sub-grouped into environmental grasp, food identification, cooking hygiene, and situation management. The adulterated food management efficacy composed of management confidence, action intention, and knowledge. Dietary lifestyle comprised of gustation, family, and health factors after factor analysis, and it consisted of all seeking group, gustation seeking group, family seeking group, health seeking group, and family and health seeking group after cluster analysis. The gustation, family and health factors were significantly affected the factors of awareness, capability and efficacy of adulterated food management (p < 0.05). The frequency of health conditions, helping with meal preparation, and the times of eating out were significantly different according to seeking groups of dietary lifestyle (p < 0.01). The scores of awareness, capability and efficacy of adulterated food management of family and health seeking group were significantly higher than the other seeking groups (p < 0.05). Conclusions: This study suggests that adulterated food management education programs should account for gustation, family and health factors of dietary lifestyle to be effective for adolescents.

The purpose of this study was to examine dietary attitudes of students and changes in their attitudes toward the school lunch service. The participants of the study were 483 students ranging from third grade elementary school students to middle school sophomores living in the Seoguipo area of Jeju Island. The subjects were asked to complete questionnaires under the supervision of their teachers or dietitians, and data were grouped into elementary school 3rd and 4th grades, elementary school 5th and 6th grades; and middle school 1st and 2nd grades for each gender. There were no significant differences among the groups with respect to their regularity of food intake, dietary considerations, or the frequency of imbalance in their diets. In the case of female participants, their frequency of snacking decreased as their grade level increased. In general, the overall changes in dietary attitudes became more negative as their grade level increased. Male students demanded increased serving sizes of both staple food and side dishes, while female students demanded increased serving sizes dishes, but not staple food as their grade levels increased. there was also an increase in the number of student sin higher grades who discarded or did not eat enough their entire meals. The major reasons for not eating the food were : no taste to the food and not proper saltiness of food. These results may suggest that school dietitians need to pay more attention to increased taste and proper seasoning of meals. Students suggested that the school lunch service should be continued, but that it needs improvement. Students in higher grades were more aware of the importance of the environment in which the meal was provided. Also, an early education in nutrition and healthy diets seemed important in preparing them for following a healthy lifestyle in later life.

Of 1,244 junior high school students of boys and girls and their families in Tokyo and Seoul, we investigated the present situations of the participation in cooking and table manners. In both countries, the average age of parents was 40's, and the ratio of the kinds of fathers' job was similar including 75% of full-time salaried workers, while that of mothers' in Japan was 63%, in Korea 23%. The male participation in cooking in both countries was found in younger generations and that of fathers and boys in Korea was significantly fewer than in Japan, which is regarded as the influence of Confucianism and employment of housekeepers. The figure of frequency of supper taken together daily was 27% in Japan and 54% in Korea where they didn't begin eating until all families gathered or the elders began. In Japan the civilities before and after meals were so often customarily expressed and they had the regular order of seats. The figure of frequency of taking meals with TV watching was about 45% in Japan of breakfast and supper and more than 30% in Korea of supper. As for the participation in cooking and table manners, national characteristics were clearly found out. In both countries, the newly modernized and democratized style of dietary behaviors was being made, rather sooner in Japan, out of the specific East-Asian traditional dining culture.

In this study, preferences and eating frequency of fish were surveyed in 390 foodservice employees in the Gyeongbuk and Daegu areas. The most common response to degree of fish intake was 'half eaten'. In the home, 'fish intake 1~2 times per a week' was chosen as the most common response. There was a significant difference(p<.05) in the frequency of fish consumption based on gender. 'Fish intake 3~5 times per a week' was most commonly chosen by subjects under 20 and over 60 years, whereas the most common response in those 41~60 and 21~40 years old was 'fish intake 1~2 times per a week'. The most preferred method of fish cooking was 'roast', 'frozen pollack' Tang was chosen as the favorite Tang(soup) dish and 'Hairtail' was chosen as the favorite boiled and grilled fish dish. Reasons for avoiding or preferring fish were related to 'tastes and recipes'. 'Mackerel' was the favorite dish for both men and women. 'Flatfish' and 'mackerel pike' were disliked by men and women, respectively. Cooked meat was eaten more often than fish regardless of gender. Besides, preference for meat was higher than that for fish in all age groups, except those over 60 years old. 'fish has good nutrition and health' was the most common response When subjects were asked to compare fish with cooked meat.

The fully implantable hearing devices (FIHDs) have been studied to compensate the defect of conventional hearing aids. Typically, a microphone for FIHDs was implanted under the skin of the temporal bone. So, implantable microphone characteristics can be affected by the eating food, chattering teeth and moving artifact. In this paper, we fabricated the physical model that was similar to characteristics of human temporal bone and skin, and we measured implanted microphone sensitivity for effect of bone conducted noise signal. For the measurement of microphone sensitivity, we applied 1 kHz pure sounds that were transmitted to implanted microphone and sine wave vibrations of varied frequency were simultaneously transmitted through the artificial bone. As a result, sensitivity of implanted microphone can be modified by bone conducted signal and this phenomenon was confirmed at varied frequency band.

Objectives: This study was conducted to investigate Chinese female marriage immigrants' dietary life after immigration to Korea, focusing on comparison between Han-Chinese (traditional Chinese) and Korean-Chinese (Chinese of Korean descent). Methods: An in-person survey was conducted with women married to Korean men, having one child or more aged 1-6 years old, and having resided in Korea for at least one year before the survey. The data were collected from the 309 respondents comprising 151 Han-Chinese and 158 Korean-Chinese in the summer of 2013. Results: Overall, there was no significant difference in dietary practice, dietary acculturation, dietary behavior, dietary habits, and food intake between the Han-Chinese and the Korean-Chinese respondents. Over 50% of the respondents ate Korean food every day. The overall level of dietary acculturation was about 3.5 out of 5 points. The average score of healthy dietary behavior was a little bit higher than 3 out of 5 points. Approximately 3/4 of the respondents showed increasing frequency of eating out. The respondents reporting increase food diversity were over 70%. Decreased frequency of skipping meal was about 60% of the respondents. Over 50% of the respondents showed increasing consumption of Kimchi, vegetables, fruit, and meat. Conclusions: Dietary life of Korean-Chinese female marriage immigrants was similar to that of Han-Chinese female marriage immigrants after immigration to Korea. The results from this study suggest that not only Han-Chinese but also Korean-Chinese should be targeted in various diet-related acculturation support programs as important multicultural populations in Korea.

Objectives: Stress during adolescence is related to undesirable nutritional intake and negatively affects the growth and development. This study was performed to investigate the relationship among life stress, dietary behaviors and the intake of high-fat containing snacks in male and female high school students in Gyeonggi-do area. Methods: The subjects were 700 high school students (350 males, 350 females) in Gyeonggi-do from July to September 2014 and the survey was performed by using questionnaire that included general characteristics, dietary behaviors, high-fat containing snacks intake, and daily life stress. Results: There was a gender difference in health-related life style and dietary behaviors, and the life stress was significantly higher in female students than in male students. For health-related life style, exercise frequency, hours of sleep and conversation time with parents had significantly negative correlations with life stress, while smoking and perceived stress had significantly positive correlations with life stress. For dietary behaviors, the frequency of eating-out had a significantly negative correlation with life stress, while the changes in amount of meal intake under stress had a significantly positive correlation with life stress. The fat intake of 'high-stress group' was significantly higher and high-fat containing snacks consumed by this group consisted of cookies, honey bread and fried foods. Conclusions: It is necessary to develop appropriate programs for the emotional stability and stress relief of adolescents that provide continuous nutrition education focused on proper snack intake, desirable dietary behaviors and nutritional aspects.

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

Objectives : The aim of this study was to investigate the evaluation of gastrointestinal parasympathetic nerve activity by comparing between HRV and bowel sound parameters in patients with functional dyspepsia. Methods : 62 patients (male 22, female 40) were enrolled. HRV was measured in all patients. and TP (total power), LF (low frequency density: 0.04$\sim$0.15Hz), HF (high frequency density: 0.15$\sim$0.4Hz). and LF/HF ratio were analyzed. HF band is a reflection of parasympathetic activity. and the LF-to-HF ratio is considered a marker of sympathovagal balance. Bowel sounds were recorded at the day after, and postprandial %BS was used to indicate the gastric vagal activity after eating. HRV and bowel sound parameters were compared. and correlation between them was analyzed. Results : There was no difference in LF/HF ratio between patient group and healthy group of other report. According to values of %BS, each patient was classified into a normal (>6 %BS) or hypoactivity (<6 %BS) of gastric vagus nerve group. HF component of the hypoactivity group was not significantly higher than that of the normal group. There was no correlation between HRV and bowel sound parameters. Conclusions : Because no correlation was found between HRV and bowel sound parameters in patients with functional dyspepsia, we concluded that it is not proper to evaluate gastric vagus nerve activity by HRV measurement.

This study was conducted to investigate the dietary adaptation and use of the university foodservice (UF) in Korea according to the residence period of foreign students. The average length of residence in Korea of t he subjects was 8.2 months. The period of residence was divided into quartiles: 1-4 months in the first quartile (average 2.2 months), 5-7 months in the second quartile (average 6.3 months), 8 months in the third quartile, and 9-66 months in the fourth quartile (average 18.3 months). The regularity of meals tended to be the highest in the 1st quartile and lowest in the 2nd quartile and then increased in the 3rd and 4th quartiles. The frequency of consumption of delivery food and convenience store food was lowest in the first quartile and highest in the second quartile and then decreased with the period of residence. The frequency of night eating increased according to the period of residence after the second quartile. The degree of adaptation to Korean foods was highest in the first quartile. The use of the university cafeteria was significantly higher in the 1st and 4th quartiles than in the 2nd and 3rd quartiles (p<0.05, p<0.01, respectively). The satisfaction with the UF decreased as the residence period increased. Based on these results, since international students are very positive and try to adapt to the dietary life in Korea in their early years of studying in Korea, it would be desirable to intensively support them to adjust to their dietary life at this time. In addition, since it takes about 18 months or more to assimilate the Korean food culture and show positive changes, it is necessary to continuously operate the Korean food culture adaptation program for international students over this period.
