  • Antioxidants such as vitamin C and E may play a preventive role in the development of cancer and coronary heart disease. The status of vitamins C and E may be affected by lifestyle habits such as smoking , drinking, and exercise. These habits can modify the dietary requirements of vitamin C and vitamin E. the purpose of this study was to determine whether Korean young healthy men and women consume vitamins C and E in sufficient quantities relative to their lifestyle habits. Among the participants in this study, 52% of the men and none of the women were smokers. ; 84% of all subjects drank alcohol more than once a week ; and the men exercised more often than the women. The concentrations of serum total , HDL-, and LDL- cholesterol were higher in the women than in the men, but the serum triglyceride concentrations were higher in the men than in the women. The men consumed less satuated fat than the women (p<0.05) . The daily intakes of vitamin C for the men and the women were 47.1mg and 65.6mg, respectively. On the other hand , the daily vitamin E intake was higher in the men (11.8mg) than women(6.9mg). The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and in no subjects were they below the minimum value of ranges. However, about 19% of male subjects and 10% of female subjects showed deficient status, although the mean serum vitamin C levels were normal . Lifestyle habits fo the sort mentioned above have little influence on the serum vitamin C and $\alpha$-tocopherol concentrations. The serum $\alpha$-tocopherol concentration had a positive correlation with total fat and alcohol consumption. The serum vitamin C concentration was positively associated with regular exercise, but it was negatively correlated with the number of cigarettes smoked. Meanwhile, the serum lipid persoxide concentration , the indirect index of oxidative stress, was influenced by certain variable such as body mass index , the number of cigarettes smoked , alcohol consumption, energy expenditure, vitamin C intake, and serum ${\gamma}$-tocopherol concentration. Serum lipid peroxide concentration was positively associated with body mass index, the number of cigarette smoked , serum triglyceride , and HDL-cholesterol concentration. In conclusion , the vitamin E requirements of the subjects were met by the Recommended Daily Allowance (RDA) regardless of lifestyle habits. However, serum vitamin C concentrations showed individual variation and was below the normal ranges. Smoking and exercise influenced serum vitamin C concentration. Therefore, a reevaluation of the requirements of vitamin C relative to lifestyle habits is necessary.

  • The purpose of this study was to investigate nutritional knowledge, practice of eating behavior guidelines, and problematic dietary habits in working high school students in comparison with non-working high school students. A survey questionnaire was formulated to obtain information on demographic variables, body size, part-time jobs, nutritional knowledge, practice of eating behavior guidelines, and dietary habits. The developed questionnaire was given out to 515 students attending a vocational high school in Yongin, Gyeonggi-Do. Those who had been working 5 hours or more per day for at least a month at the time of survey administration were defined as working students for this study. Proportions of working students were similar between male and female students (i.e. 49.5% for male, 50.5% for female). No significant difference was found in scores of nutritional knowledge between working ($8.43{\pm}2.29$) and non-working students ($8.60{\pm}2.19$). However, some dietary habits were found to be dependent on working status. While approximately 43% of non-working students reported skipping a meal, about 57% of working students did so (p<0.01). The proportion of students with any drinking experience was significantly higher among working students (92%) compared to non-working students (80%) (p<0.001). Working students were found to drink alcoholic beverages more often than non-working students (p<0.001). The mean score of practice of eating behavior guidelines was lower in working students than non-working students. The magnitude of this difference was modest ($51.33{\pm}0.63$ in working students, $53.40{\pm}0.51$ in non-working students), but reached statistical significance (p<0.01). Based on the findings from this study, it is suggested that specific behavior-oriented messages to improve certain problematic dietary habits need to be directed toward working high school students.

  • This study attempted to analyze the health habits affecting health status of industrial workers. Data was collected from 57 industries of 900 workers at Inchon. The research has been carried out through self-administered questionnaire and from the analysis of the health examination records and the results were as follows: 1. Among 861 respondents, men were 81.2%, women were 18.8%, 42, 6% were of the 30-40 age group, the married were 65.7%, the single were 32.5%, the high school graduates were 62.4% and 37.3% were of people who worked between 1 and 5 years. 2. As far as the seven health habits, current smokers were 54.9%, people who regularly exercise was 31.7%, 7-8 hour of sleep, on the average were 74.0%, people eating breakfast nearly every day were 8.0%, and people eating between meals almost every day were 54.2%. Heavy drinkers who drink 3-4 times or more per week were 13.2%, 1-2 times per week were 26.8% and the obese were 4.6%, 3. Health status of A and B, estimated by doctors in the health examination were 81.7% and C, D1, D2, the unhealthy were 18.3%. Men were reported more than women in unhealthy groups and the results regarding health status reflect gender, educational level and age, That is to say that, lower educational level group and over 30 years of age group perceive their health to be worse than the higher educational level and under 30 age group, And these differences were statistically significant. 4. The relationship between health habits and health status, expressed in terms of the odds ratio. Current smokers had a consistently worse health status than a nonsmokers with a 1.36 odds ratio. The workers who reported eating breakfast rarely or never were more associated with the unhealthy group than the regular breakfast eating group with a 2.48 odds ratio. One or more drink per week had a worse health status than a never or a little drinker with a 1.42 odds ratio. 5, The Health habits score and duration of work were selected as significant factors influencing health status based on logistic analysis. According to the results of this model, the odds ratio of good health status was 2.06 for good health habit score, 1.55 for population who worked seven years or more duration of work. As we have seen, good practices were found to be associated with better health and the effect of the health habits was cummulative;those who followed 6-7 health habits were in better health, even though they were older than those who failed to do so. Therefore, in order to provide the health promotion of workers it is necessary to establish a health management plan for an effective health education and health service. If we use this type of study as a prospective study design, we can get a precise basic data for health promotion and a management plan for industrial workers.

  • 본 연구에서는 스마트폰 사용자의 사용습관 및 하드웨어 특성이 스마트폰의 기능 수행도에 어떻게 영향을 미치는지를 알아보았다. 특히 스마트폰 기능 요소와 사용습관과의 상관관계를 이해하는데 중점을 두었다. 기능성으로는 전부 11 종류의 기능 요소를 정의하였다. 스마트폰 특성은 하드웨어적 특성 및 사용자 사용습관 특성으로 정하였다. 스마트폰 기능별 실측치를 구하기 위해 전부 80명으로 구성된 평가단을 편성하였다. 평가단은 미리 정의된 11개의 기능 요소들에 대해 각 기능 수행에 실제로 소요되는 시간을 스톱워치를 이용하여 측정하였으며 각 기능 요소별로 5회씩 관측하고 데이터를 수집하였다. 기능 요소별 실측치를 종속변수로, 설문지를 통해 수집한 하드웨어 특성, 사용자의 사용습관 등을 전부 12개의 독립변수로 분류하여 Minitab ver.14를 이용하여 회귀분석을 실시하였다. 전반적으로 볼 때, 스마트폰 사용자의 인구통계학적 특성, 하드웨어 특성은 기능 수행에 크게 영향을 미치지 않았다. 그러나 스마트폰 사용습관과 관련한 변수들은 전체적으로 스마트폰 기능 수행도에 커다란 영향을 미쳤으며 그 결과, 과제 수행 시간이 증가하였다. 단순입력 변수 또는 시청 변수에서는 사용성에 미치는 영향은 비교적 미미했지만, 적극 활용 변수에서는 전화걸기, 전화번호 찾기, 사전 검색을 제외한 모든 과제에서 수행시간이 10% - 30%로 크게 증가하였다. 지금까지 스마트폰의 사용자 인터페이스 방식이 크고 단순한 방식으로 일률적으로 제공되었다면, 사용습관이 다양한 계층은 입력 방식이나 과제 처리 방식에 있어서 좀 더 복잡하고 다양한 형태의 인터페이스 방식이 제공되더라도 충분히 활용할 수 있다고 생각한다.

  • The purpose of this study was to analyze the nutritional status and dietary habits in predialysis patients of chronic renal failure(CRF). The patients group was composed of total 35 persons with chronic renal failure(diabetes exclusion), male 20, female 15 who were treated in the kidney internal department and the control group also composed of 35 persons, male 18, female 17 who were classified as normal by the medical examination. Their dietary habits, nutritional status and nutritional knowledge were investigated from two general hospitals in Inchon, middle of this year 2002. There were 31.4% of low weight patients (BMI below 20), 77.1% of anemia patients (serum hemoglobin below 12g/㎗), 6S.6% of hypertension patients with diastolic blood pressure over 90mmHg, 80% with systolic blood pressure over 140mmHg, 20% of hypercholesterolemia patients (serum cholesterol over 230mg/㎗), and 22.9% of hyperlipemia patients (serum triglyceride over 200mg/㎗). The cardiovascular disease seemed to be caused by the abnormality of lipid metabolism. The possibility of the bone disease was shown from patients of hyperphosphatemia (serum phosphorus over 4.7mg/㎗, 22.9%) and hypocalcemia (serum calcium below 8.4mg/㎗, 25.7%). Intake of insufficient calories which was caused by the lack of appetite affected on the nutritional status. The intake of most nutrients was not significantly different from the RDA for Koreans. Consequently, the patient groups took a lot of salt even after the diagnosis of CRF. But patients ate 6.lg of salt which were more than the recommended amount 2∼4g for patients with CRF. The patient groups, who had the experiences of nutritional counselling, had significantly higher nutritional knowledge related to CRF than control group. Unfortunately, patients could not have enough chances for nutritional counselling by the nutritionist even though they needed the nutritional informations and dietetic treatments. The continuous research is expected with regard to the detail plan for the improvement of nutritional support and the nutritional counselling because it is important to decide the requirements of nutrients for patients with kidney disease, considering the kidney function and status of nutrition.

  • Feeding habits of white croacker, Pennahia argentata, were analyzed by using the stomach contents of 153 specimens caught by bottom trawl from May 2011 to March 2012 in the Sejon island, Korea. To know feeding habits of the white croacker, P. argentata, a species composition and it's fluctuation were analyzed based on growth. White croacker, P. argentata caught in the area composes 15 species. The most species in an number of the prey was Macrura which was occupied at 66.4% from whole prey, the second most species was Pisces which was occupied at 20.3%. The most species in an wet-weight of the prey was Pisces which was 49.3% out of the whole specimens. The second most species was Macrura which was 43.3%. The frequency occurrence of the prey was Macrura which was 68.6%, the next one was Pisces which was 28.8%. The highest Index of Relative Importance (IRI) of the prey was Macrura which was 78.2%, the next one was Pisces which was 28.8%. A number of the prey per specimen of small, middle and large class were 1.3, 1.5, 1.7, respectively. A wet weight of the prey per specimen of small, middle and large class were 0.2, 0.6, 0.2 g, respectively.

  • We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of their nutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, $21.5kg/m^2$ and -1.2% in male students and 27.3%, $21.2kg/m^2$ and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in under weight students than in students of normal and over-weight. Female students were found to skip meals and consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eaten as well as the frequency of eating salty foods. These results suggest that in order to assess obesity properly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

  • Purpose: This study investigated the dietary patterns associated with Korean food and the level of proper eating habits according to recognition of the Kimchi cooking method, and aimed to suggest the necessity of dietary education of traditional foods such as Kimchi. Methods: Based on the results of the national dietary survey conducted in 2014 by Ministry of Agriculture, Food and Rural Affairs of Korea, a total of 1200 subjects were classified into two groups, one that knew how to make Kimchi (53.8%) and another that did not (46.2%). Results: The group that knew how to make Kimchi (FG) showed significantly higher scores in knowledge of how to cook most types of Korean foods and traditional fermented foods than the other group (NG). Moreover, FG showed significantly higher scores in regularity in meals and a higher frequency of Korean foods such as rice, Kimchi, and grilled or stewed food, while it showed significantly lower scores in dietary risk factors than NG. In addition, FG showed significantly higher scores in dietary education interest and number of meals with family during the week than NG. Finally, FG had significantly higher scores in the degrees of practice of all eight items related to proper eating habits. Conclusion: Since recognition of Kimchi cooking has a great influence on maintenance of dietary life, dietary education to improve the cooking ability of traditional foods should be further strengthened.
