본 연구는 학교급식 식재료의 위생관리 실태를 파악하기 위하여 식재료 생산 가공업체의 생산직원 221명을 대상으로 위생지식을 조사하고, 위생관리 수행수준, 위생관리 현황을 5점 척도로 평가하였다. 생산직원의 위생관리 수행수준의 평균은 4.63/5.0점으로 높은 편이었으나, 위생 지식수준은 4.63/9.0점으로 낮았다. HACCP 인증업체 직원의 위생교육 횟수, 만족도, 위생관리 태도 등이 비인증업체에 비해 유의하게 높았고(p<0.05), HACCP 비인증업체에서의 시설설비에 대한 관리가 요구되었다. 또한 위생관리 수행영역에서 작업대와 작업장의 매일 청소 및 철저한 소독, 냉장고와 냉동실의 청결유지, 작업장의 온도확인, 작업 중 교차오염 방지, 작업 중 작업도구의 철저한 소독, 작업장 출입 시 신발소독 및 에어샤워, 작업복의 매일 세척의 항목은 HACCP 비인 증업체에서 유의하게 잘 지켜지지 않아 위생교육 및 평상시 작업관리 시 철저한 관리가 요구되는 항목이었다. 생산직원들이 학교급식 식재료를 생산하면서 가장 어려운 점은 위생관리와 납품시간 맞추기였고, 위생교육의 불만족한 이유는 일방적인 강의 때문이 가장 높았다. 따라서 생산 가공업체 에서는 교육대상자의 요구에 맞추어 위생교육 내용을 선정하고, 일방적인 강의형식의 교육보다는 활동자료나 교육매체를 활용한 보다 능동적이고 흥미로운 위생교육을 실시하여 교육효과를 최대한 높일 수 있도록 하여야 할 것이다.

This study was designed to determine the antioxidant activity of solvent fractions of broccoli sprouts grown by controlling the growing environment at the plant factory system. Fractionation was achieved with chloroform, n-hexane, ethyl acetate, butanol, water by 70% EtOH extract of the broccoli sprouts. Each solvent fraction was put through TLC and HPLC to separate active components. Higher antioxidant activities were observed for the butanol and ethyl acetate layers. Further evaluation of each of the 5 layers (LH1 to LH5) of the butanol fraction showed that the refined LH3 extract had a high antioxidant effect. Components with similar Rf values from TLC had the same retention times and peaks in the HPLC analysis. It was also determined that the sulforaphane content was high at the chloroform and butanol layers and the sulforaphane was responsible for, the high antioxidant activity. Thus, to use for functional materials, the butanol extract/layer of broccoli sprouts is recommended as the most effective.

Inadequate dietary intakes and poor health behaviors are of concern among rural residents in Korea. This study is conducted to compare dietary intakes, dietary diversity score (DDS), mean nutrient adequacy ratio (MAR) and health related behaviors by rural, factory and urban areas in Asan. A total of 930 adults (351 men and 579 women) were interviewed to assess social economic status (SES), health related behaviors and food intakes by a 24-hour recall method. Mean age was 61.5 years with men being older (64.8 years) than women (59.3 years, p<0.001). Men in the factory area were older than rural or urban men while urban women were the youngest. Education and income of urban residents were higher than other area residents. There were more current drinkers in urban area while smoking status was not different by regions. Physical activity was significantly higher in rural or factory areas, whilst urban residents exercised more often (p<0.05). Rural or factory area residents considered themselves less healthy than others while perceived stress was lower than urban residents. Energy intakes were higher in urban residents or in men, however, after SES was controlled, energy intake did not show any differences. Energy-adjusted nutrient intakes were significantly higher in the urban area (p<0.05) for most nutrients except for carbohydrate, niacin, folic acid, vitamin $B_6$, iron and fiber. Sodium intake was higher in factory area than in other areas after SES was controlled. DDS of rural men and MAR of both men and women in the rural area were significantly lower when SES was controlled. In conclusion, dietary intakes, diversity, adequacy and perceived health were poor in the rural area, although other health behaviors such as drinking and perceived stress were better than in the urban area. In order to improve perceived health of rural residents, good nutrition and exercise education programs are recommended.

The study results regarding the ingredient differences, sensory characteristics, purchasing type, usage and improvement direction for home-made traditional doenjang and factory produced commercial doenjang are as follows. The L-value indicates that home-made traditional doenjang has a higher value in average than the factory produce done, and the a-value indicates the opposite. Home-made traditional doenjang had higher water content than commercial doenjang ; however the pH values of commercial doenjang and home-made were 5.34 and 5.32 respectively, which was very similar. Factory produced commercial doenjang showed higher protein content than the home-made traditional doenjang. Regarding the correlation between ingredients, there was a significantly negative relationship between the L-value and a-value but a significantly positive relationship between the L-value and b-value. There were no significant relationship with water content, pH and protein content. For the color and taste, which are the sensory characteristics, commercial doenjang showed higher value than the traditional doenjang, but for smell, the values were similar. Regarding grittiness, the factory produced commercial doenjang had bigger particles than the traditional doenjang. Preference was a bit higher in the traditional doenjang. Of the 380 study subjects, most were from 40 to 49 years old (65.5%), and the most family type were nuclear families which was a total of 400 people (69%). Moreover, the most residential type was apartment which was 355people (61.2%), and for the monthly income, more than 2,510,000won was 48.3%. For the educational background, college education was 304 people (52.4%), and high school education was 199 people, 34.3%. In the usage, most of the people eat doenjang more than once a week, and usually their parents make the doenjang. People used both commercial doenjang and home-made traditional doenjang >home-made only >factory produced commercial doenjang only in that order. The reasons for using the home-made traditional doenjang aredelicate taste and flavor>more nutritious> anti-cancer ingredients in that order. The reason they use the factory produced commercial doenjang is because they don't know how to make it at home. The things that needed to be improved in the home-made traditional doenjang are bad smell> entire quality> flavor> color in order, indicating that studies for reducing bad smell are required. The things that needed to be improved in the factory produced commercial doenjang are taste & flavor> entire quality>bad smell> color in that order, indicating that people are more concern about it tasting like home-made than the smell. From the above results, we can see that better functional doenjang should be developed for family health and to increase the consumption of the doenjang, which has good functional psychological activities, also more various types of foods that use doenjang and scientific studies to reduce the home-made doenjang smell should be continuously studied. Moreover, studies on how to make the factory produced commercial doenjang taste more like traditional doenjang should be performed.
