In the present study, we conducted in-depth interviews with school dieticians and nutrition teachers to determine the local foods they were aware of and their experiences with local foods. We also aimed to obtain more detailed measures for local food vitalization and suggestions for improvements. In-depth interviews were performed with 8 school dieticians and nutrition teachers, who stated that local food vitalization was needed for school food services, because it could be a foundation for securing safefood products, student healthi mprovements, environmental protection, and the establishment of a general consumption market. However, they were aware of a higher number of disadvantages than advantages in school situations and indicated the deterioration of the quality of food products as the biggest disadvantage. The most-suggested measurement items for local food vitalization in schools included improvement of the food distribution system, expansion of education, information sharing, prevention of monopolies, improvement of food-product quality, and mass production. In addition, it was suggested that school dieticians and nutrition teachers should invest efforts in the development of excellent recipes and varied diets utilizing local foods. Therefore, system supplementation is urgently required in order for school food service officials, and consumers, to efficiently introduce and vitalize local foods. It is also necessary to foster an environment that encourages trust-based relationships with producers to maximize the effect of system supplementation. This would be the foundation for improving the health of students, improving food-service quality, nutrition management, and vitalization of the regional economy in the future, and will positively affect students’ food consumption patterns even after they become adults.

Previous reports revealed that DMfree (green tea extract) inhibited expression of the IL-6 gene in Mycobacterium lepraeinfected MSCs (mesenchymal stem cells). This study aimed to measure IL-6, IL-1β, TNF-α and PGE2 production in M. leprae-infected MSCs using ELISA. To confirm the effect of DMfree on IL-6 and signal transduction, a western blotting test was performed. DMfree inhibited the expression of IL-6 in the MSCs and the heterodimer of STAT3, which also affects the expression of multiple genes. Though DMfree pre-treatment of control MSCs produced a baseline level of IL-6, it significantly inhibited the production of IL-6 in M. leprae-infected MSCs. There was no significant difference in IL-6 production between 1 and 7 day treatment groups. M. leprae-infected MSCs produced more IL-1β, TNF-α and PGE2, but DMfree could not inhibit their production at a physiological concentration. This is different from other reports that used higher concentration of EGCG treatment, resulting in significant inhibition of the cytokines. The inhibition appears to be related to the concentration of EGCG. These results indicate that DMfree can alleviate inflammation involving IL-6.

The purpose of this study was to determine the effects of awareness and knowledge of the efficacy of carbonated water on consumption patterns and satisfaction for college students, who are the principal consumers of carbonated water. A survey was conducted with 502 college students in the Metropolitan area from May 13 to 18, 2015 and 455 questionnaires were analyzed. As for the differences in awareness and knowledge of the efficacy of carbonated water according to gender, females (14.60 and 0.76) had better awareness and knowledge than males (13.40 and 0.58) (p=0.000 and p=0.036). The more positive the awareness of carbonated water, the greater the knowledge (p=0.000); the greater the knowledge of carbonated water, the higher level of consumption satisfaction (p=0.006). The odds ratio of awareness for carbonated water was 11.98; that is, positive awareness led to higher levels of satisfaction than negative awareness (p=0.003). Since awareness of the efficacy of carbonated water was found to affect carbonated water drinking and satisfaction, it is necessary to provide correct information about the efficacy of carbonated water.

This experiment was carried out to find the quality characteristics of yanggaeng added antioxidant rich collagen powder in the color, sugar contents, texture, radical scavenging activity and electronic nose detected flavor. L value and a value kept decreased as the more collagen powder was added in the yanggaeng while b value was increased significantly at the same time. Sugar contents was increased significantly from 43 °Brix in the control to 48% in the 10% treatment (p<0.05). Hardness in the 10% treatment of collagen powder increased biggest among the treatments but springiness decreased when hardness increased. And adhesiveness, cohesiveness, gumminess and chewiness were also increased with more the collagen powder in the treatments, therefore 10% treatment showed biggest result significantly. Radical scavenging activity kept increased with higher addition of collagen powder and it resulted 60% of radical scavenging activity in the 10% treatment. In the flavor test under electronic nose experiment, 10% of collagen powder treatment was believed it flavored most for it was found in the furthest from the AIR location. Control was found also in the nearest from the AIR, which meant it has least flavor than any other treatment. Also 2.5% and 5% of collagen powder added treatments showed little differences of flavor from control, which meant 5% of treatment was believed idea condition in the treatments. With the above experimental results, 5% of collagen powder treatment in the yanggaeng manufacturing was chosed as the best mixture ratio in the test.

Although the NutriPlus program has shown considerable evidence of enhancing users’ nutritional status, the budget does not cover all eligible mothers and children. This study aimed to conduct a cost-benefit analysis of the NutriPlus program to assess its economic efficiency. 53 families with 79 users in the NutriPlus program at Daejeon Dong-gu Health Center participated in this study with informed consent. The costs and benefits were estimated from both the administrator’s and users’ perspectives. We converted the time cost into Korean currency based on the minimum wage in 2014. The value of nutrition education and service (B2), estimated by contingency valuation method (CVM), was counted as an economic benefit. 6 families (11.3%) were recipients of national medical care and 22 families (41.5%) paid 10% of the food package cost by themselves. The total cost was 7,450,167 and the total benefit was 12,402,239. The budget for the health center (C1+C2+C3+C4) was 5,984,381 a month. Time and transportation cost for receiving nutrition education (C6) differed significantly according to the economic status of families. Household food consumption increase (C4-B4) was 40,379 in the poverty group, which was four times more than in the other groups. The net benefit (B-C) was 4,852,172 and the B/C ratio was 1.66. Therefore, the NutriPlus program is beneficial in the economic aspect as well as in the nutritional aspect. If the enhancement of nutritional status was also considered, the total benefit would be even higher. These results confirm the legitimacy of a secure budget for the NutriPlus program. And we suggest expanding its budget to cover more eligible individuals to improve people’s health and welfare.

Cronobacter spp.는 Salmonella spp.와 함께 조제분유에서 발견되는 미생물 중 위험도가 가장 높은 category A에 속하는 균으로 알려져 있다. 1958년 영국에서 처음으로 유아의 뇌수 막염의 원인균으로 보고되었으며, 감염 후 신생아에게서 괴사 성 장염, 패혈증 등을 일으켜 후유증으로 시력과 청력 상실 및 신경마비를 일으키기도 한다. 이러한 위험성 때문에 Cronobacter spp.의 신속 검출 및 진단은 식중독 예방에 있어서 중요하다. 따라서 2002년 미국 식품의약품안전국에서는 분유에서의 Cronobacter spp.를 EE broth, VRBG 배지를 이용해 균을 분리 하고, TSA 배지에 순수분리 후 노란색을 발하는 colony를 생 화학적 실험을 통해 검출하는 방법을 제시했다. 또한, 우리나 라 식품공전에서도 배지를 이용하여 Cronobacter spp.를 검출 하는 방법에 대해 등재하였다. 하지만 배지배양법을 기반으로 하는 Cronobacter spp.의 검출방법은 검출에 소요되는 시 간과 노동력 등이 비효율적이라는 단점이 있다. 따라서 많은 시간이 소요되는 배지배양법을 보완하고자 PCR, real-time PCR 방법 및 최근에는 PCR기법과 ELISA, CE-LIF 등을 결합 하여 검출하는 방법이 개발되어 Cronobacter spp.의 검출에 사용되기도 하였다. Cronobacter spp.의 검출에 사용되고 있는 분자생물학적 기반의 PCR 및 real-time PCR 기법은 민감도와 특이도가 좋으며, 배지배양법에 의한 검출방법에 비해 검출 시간을 획기적으로 줄일 수 있다는 장점이 있다. 하지만 까다 로운 실험과정과 조작에 있어서 필요한 전문적인 기술이 필요 함은 한계점으로 사료된다. 면역학적 방법에 의한 Cronobacter spp. 검출에 관한 연구를 통해, 분석에 소요되는 상당시간을 단축할 수 있었으며, 민감하고 특이적인 검출이 가능함을 보 여주었다. 특히 일부 연구보고에서 면역학적 검출방법은 고가 의 장비가 필요 없으며, 간단한 지침에 따라 모니터링 업무의 수행이 가능하다고 하였다. 면역학적 검출방법에는 ELISA 방법 외에도 immunomagnetic bead, liposome, immunochromatographic strip 등이 개발되고 있다. 우리나라 식품의약품안전처에서는 영․유아 대상 식품의 안전관리를 강화하고자 Cronobacter spp.에 대해서는 ‘불검 출’로 기준을 설정․운영하고 있으며, 지속적으로 이에 관한 규정을 강화하고 있는 실정이다. 따라서, 식품산업체 및 식품 의 제조, 가공, 유통 현장에서 쉽게 모니터링이 가능하며, 신 속, 민감하고 특이적인 검출방법의 개발은 지속되어야 한다.
