This study examined the attitude and education need for food safety of high school students. Data were collected from 297 high school students in Gyeongbuk province through a self-administered questionnaire on December, 2008. Frequency, t tests, one-way analysis of variance, Duncan's multiple range tests, and chi-square tests were conducted using SPSS V. 14.0. Many respondents answered that the foods produced and distributed in Korea were not safe enough. Over a third of the respondents replied that the produced and distributed foods were not safe because of unsanitary food processing. They pointed out food additives threatened food safety the most, which was followed by heavy metal contamination, and endocrine disruptors. Most respondents mentioned difficulties in acquiring information concerning food safety, and obtained information from the media, such as TV and radio. The respondents required a high level of education regarding food safety, and preferred movie clips and broadcasting media the most. Finally, they pointed out food-related government organizations to be the most efficient educational institution for food safety.

[Purpose] To date, there have been no studies on the response of wrist tremor to increased muscle activity during exercise. This study aimed to evaluate the wrist tremor response with increasing muscle activity during bench press exercise. [Methods] Triceps muscle activity and wrist tremor response were measured by electromyography and an accelerometer, respectively, during bench press exercise in 11 healthy men without weight-training experience. Subjects performed bench press at 30% repetition maximum (RM), and the rating of perceived exertion (RPE) and lactate concentration were measured before and after exercise. One week later, an equivalent number of bench presses at 30% RM was performed without weight load as a control trial (CT). [Results] RPEs and lactate concentrations significantly increased after resistance exercise (30% RM) from 7.4 to 14.3 and 1.7 to 4.9, respectively (P<.01), but no such difference was observed in the CT. Muscle activity linearly increased during the 30% RM exercise, and wrist tremors were shown to linearly decrease. A strong negative correlation was observed between the two variables (r=-0.88, P<.001). [Conclusion] We found that wrist tremors during resistance exercise, as measured using an accelerometer, can be used to predict muscle activity.

본 연구에서는 콩에서 유래한 단기 발효식품인 청국장, 물두시, 낫또 제품 중 대표적인 제품을 각각 하나씩 선택하여 이들의 일반적 특성과 항돌연변이 효능 및 항암 효능을 비교 연구하였다. 청국장은 아미노태 질소 및 암모니아태 질소의 함량이 높았으나, 낫또는 그 함량이 낮게 나타났다. 물두시의 경우 여타 발효식품에 비해 pH가 낮고 산도가 높았다. Ames test 및 HT-29 인체 대장암세포를 이용한 실험에서는 청국장이 우월한 항돌연변이 및 항암 효능을 나타냈다. 이상의 결과로 볼 때 청국장은 전반적으로 기능성이 우수한 것으로 나타났으며, 물두시는 낫또에 비해 기능성이 더 나은 것으로 나타났다. 이는 발효 기간의 차이, 제조방식, 원재료의 품질 등에 의한 것으로 여겨지며, 향후 각국의 식문화 및 조리 방식 등의 차이에 기초를 둔 추가적인 연구가 필요할 것으로 여겨진다.

This study evaluated the effectiveness of a visiting inspection and knowledge-based food safety education program for cooks in child care facilities provided by the Center for Children's Foodservice Management (CCFSM). The research was conducted among cooks at 91 child care facilities; 56 existing facilities had been enrolled since 2011 and provided with the inspection and education program for 2 years and 35 new facilities were enrolled in 2012 and provided with the program for 1 year. The food safety knowledge of the cooks of the two groups were compared by the presence and duration of inspection and education programs provided by the CCFSM. The total mean score for food safety knowledge was $18.48{\pm}3.09$, with a group score of $19.34{\pm}2.68$ for the existing facilities and $17.11{\pm}3.25$ for the new facilities (P<0.001). There was no significant difference between groups in the knowledge of the personal sanitation. According to a post-test for food safety knowledge in the two groups after the completion of a one-year program on food safety by CCFSM, the mean score of food safety knowledge increased by 2.92 to 20.03 for cooks of the new facilities and both groups had significantly higher mean scores than pre-test (P<0.001). There was no significant difference in the mean score of each group by post-test. Thus, the one-year continuous program by CCFSM was effective in improving food safety knowledge of the cooks of the child care facilities.

The purpose of this study was to investigate the dietary habits and altered food preferences of stroke patients. One hundred and forty-six outpatients, who had experienced their first-ever stroke and were admitted to Asan Medical Center between July and December 2000, were studied. Using interviews, we assessed the altered food preferences, food consumption frequency, and other factors influencing the food preferences and food consumption frequency of the subjects. These results were analyzed with 2 t-tests, and multiple regression analysis, using the SPSS package program. Preferences for pork, red fish, coffee, bread and stews were higher in male stroke patients than in females. The frequency of consumption of beef, pork, white fish, red fish, egg, garlic, onion, coffee, instant noodles, bread, and culinary vegetables increased in the male stroke patients more than in the females. Food preferences were influenced by income, risk factors, subjective tastes and location of brain ischemic lesions. Food consumption frequency was affected by food preference, income, drugs, alcohol, marital status, sex, and dysgeusia. As a result of multiple regression analysis, the frequency of consumption of white fish, red fish, eggs, soy milk, milk, garlic, onions, coffee, noodles, bread, bean-paste stew, kimchi, culinary vegetables, and greasy foods were the most affected by each food preference. Our results suggest that food consumption frequency may vary with food preference, income, drugs, alcohol, marital status, sex, and dysgeusia, and nutrition education should be formulated to prevent stroke recurrence based on the food preferences, subjective tastes, and risk factors of individual stroke patients.

Objective : We estimated the number of Korean adults with back pain and evaluated population-based associated factors of back pain from a representative sample data from the Fourth Korea National Health and Nutrition Examination Survey. Methods : The number of Korean adults who experienced back pain (experienced patients), those who experienced back pain lasting for three or more months during the past year (chronic patients), and those who were currently suffering from back pain (current patients) were estimated by analyzing the data from the fourth Korea National Health and Nutrition Examination Survey conducted in 2007 using surveyfreq procedure of the SAS statistical package. Population-based odds ratios for being experienced, chronic, and current patient according to demographic (age and gender), socioeconomic (education and occupation), and lifestyle factors (smoking, drinking, and exercise) were estimated using surveylogistic procedure. Results : It was estimated that there were 5,554,256 (proportion, 15.4%; 95% CI, 4,809,466 - 6,299,046) experienced patients, 2,060,829 (5.7%; 1,557,413-2,564,246) chronic patients, and 3,084,188 (8.5%; 2,600,197 - 3,568,179) current patients among 36,107,225 Korean adults aged 20-89 years in 2007. Each of explanatory variables was significantly associated with at least one of the response variables for back pain. Conclusion : Based on our study results, further efforts to investigate epidemiology of back pain, to evaluate associated factors, and to improve treatment outcomes are needed.

This study was performed to estimate serum 2S-hydroxyvitamin D (25-OHD) level in wintertime and to evaluate the relationship between serum 25-OHD level and associated factors in 50 premenopausal working women aged 30-49 y in Busan. The serum 25-OHD level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake was assessed by questionnaire including information about outdoor activity time, daily activity diary and 24hr recall method. The mean vitamin D intake was $4.24{\mu}g$, which corresponded to 84.9% of the Korean RDA. The mean level of serum 25-OHD was 25.7 ng/mL. Vitamin D deficiency (25-OHD < 7nmol/L) and toxicity $(25-OHD{\geq}75\;nmol/L)$ were not found in the subjects. However, the prevalence of vitamin D insufficiency (25-OHD < 15 nmol/L) and hypovitaminosis D (25-OHD < 30 nmol/L) were 12% and 60% respectively. The serum 25-OHD level showed positive significant correlations with the duration of outdoor activity per weekdays (p < 0.05). Our findings suggest that hypovitaminosis D was common in the subjects in wintertime. So nutritional education for increasing outdoor activities is needed for premenopausal working women to increase vitamin D status in wintertime.

Purpose: The purpose of this descriptive study was to identify the discharge nursing needs of patients who received gastrectomy. Method: The subjects of this study consisted of 100 patients who had gastric surgery in 4 university hospitals in chungnam province. The instrument for this study was developed by the researcher based on literature through in-depth interviews. Data was collected from October 4 to October 30, 2000. Result: The results were as follows: Discharge nursing needs were classified in 8 main categories. The 8 categories were 'emotional and spiritual support', 'nutrition and diet control', 'medication', 'treatment planning and follow up care', 'activity level', 'symptom management' 'health seeking behavior' and 'social support'. The total mean score for nursing needs was 3.89. 'Nutrition and diet control' was the highest degree of nursing needs and 'activity level' was the lowest degree of nursing needs. There were significant differences in degrees of nursing needs between different ages(F=2.74, p=.048), level of education(F=2.91, p=.038) and period since diagnosis(F=4.46, p=.037). Conclusion: This study looked at 8 categories of discharge nursing needs. Patients identified 'nutrition and diet control' as the highest need and 'activity level' as the lowest need. Further research needs to be done to identify discharge educational needs for various age groups, educational level and for patients with varing lengths of diagnosis time to surgery.

This study was designed to find out opinions about free congregate site meals that the program served to improve nutritional status of low socio-economic elderly. This study was conducted in Sungnam-shi. The purpose of this study provided the baseline data to extend the meal service program in this area. Five hundred samples were selcted by the propotion of population in three districts(Sujung-gu, Jungwon-gu, Bundang-gu). The result were as follows. 72.8$\%$of subjects were women and 27.2$\%$of subjects were extended family type. Seventy$\%$ of respondant were not aware of the free meal service for elderly. Major channels of information about free meal service were mass media(33.8$\%$)and advertisement material from city (24.3$\%$). The rate of recognition and channels of information about free meal service were different according to demographic characteristics of subjects. Sixty-eight of subjects pointed that the meal service program was highly necessary in these areas and the necessity of the program was not significantly different by socio-economic variables. The group who know about free meal service had a positive attitude toward supporting the meal service program. Women preferred labor volunteers(46.8$\%$)at meal service center and men preferred donations. According to levels of education each group preferred different types of surpport for free congregate site meals for elderly. (Korean J Community Nutrition 2(2) : 246~255, 1997)
