Lake Tinisu Abaya is home to some fish species. The lake's native fish species include Barbus and Tilapia zilli. Tilapia fish (Oreochromis niloticus L.) were stocked in Lake Tinishu Aabaya in 1997. This study aimed to investigate the feeding behaviors of O. niloticus in Lake Tinishu Abaya to develop an appropriate fisheries management approach in the lake. 428 O. niloticus fish samples (2.5 to 30.9 cm and 1.1 to 475 g) were collected to calculate the diet composition. Out of the total of 428 gut contents examined, 55 (12.85%) were found to be empty and 373 (87.15%) to be containing one or more food items. The diet behavior of the stocked fish in the study lake revealed that phytoplankton (39.5% by volume) and macrophytes (25.81% by volume) were the most noteworthy food items followed by detritus (14.39%) and zooplankton (12.95%). With increasing fish size, the importance of phytoplankton, macrophytes, and detritus increased while the contribution of zooplankton, insects, and other foods with an animal origin decreased. Seasonal variation in the diet composition of fish was evident (t-test; p < 0.05). Macrophytes, zooplankton, and detritus were the dominating food items during the wet season, while phytoplankton predominated during the dry season. This study demonstrated that O. niloticus had phytoplanktivores that primarily consumed phytoplankton and that the seasons and fish size had a significant impact on their feeding preferences. The diet of O. niloticus in Lake Tinishu Abaya comprised foods with both plant and animal origins. It concludes that the dietary habit of O. niloticus in the lake is, generally, the omnivorous type.

Since atopic dermatitis requires continuous care, the role of a patient's parents is important. However, the majority of parents cause even more serious situations by limiting allergy-inducing foods too much, causing an imbalance in nutrition and decline in immunity. Therefore, educating parents systematically and repeatedly via personal computer or smart phone could help to prevent and manage atopic dermatitis. In this study, 126 recipes of 4 seasons were developed for the parents of atophy students by using food with least chemical additives. After developing these recipes, a blog named "Atop" meaning "atophy stop" was made with these recipes and cooking step photos. In this blog, the visitors who used these recipes showed improvement responses of atopic dermatitis management. The results of this study show that further nutrition education programs such as this blog should be developed continuously and an effective evaluation tool must be also developed for the further prevention and management of atopic dermatitis.

This study was conducted to develop a nutritional education program based on the health belief model to improve nutritional status among Vietnamese female marriage immigrants in Korea. The education program was developed through literature review, focus group interviews, expert consultation, and pilot tests. Based on theoretical requirements and needs of beneficiaries, the education program was consisted of 16 sessions with nine topics: 'how to evaluate own dietary habits and nutritional status', 'health problems according to dietary habits and nutritional status', 'understanding six food groups', 'healthy eating plan', 'understanding food cultures of Korea and Vietnam', 'traditional and seasonal Korean foods', 'how to cook Korean food', 'nutrition management of family members', and 'practicing of healthy dietary life'. Program contents in each session consisted of activities that could induce outcome and value expectations, self-efficacy, perceived benefits, and barriers and cues to actions regarding dietary behavior. This nutritional education program based on the health belief model would be helpful to implement healthy diet behaviors in Vietnamese marriage immigrants and their families. Extension of these nutritional education programs to health centers and multicultural family support centers would improve the current poor nutrition status of Vietnamese marriage immigrant women. Further studies are needed to validate our program.

Demand forecasting is a crucial task for an online retail where has to manage daily fresh foods effectively. Failing in forecasting results loss of profitability because of incompetent inventory management. This study investigated the optimal performance of different forecasting models for a very short shelf-life product. Demand data of 13 perishable items with aging of 210 days were used for analysis. Our comparison results of four methods: Trivial Identity, Seasonal Naïve, Feed-Forward and Autoregressive Recurrent Neural Networks (DeepAR) reveals that DeepAR outperforms with the lowest MAPE. This study also suggests the managerial implications by employing coefficient of variation (CV) as demand variation indicators. Three classes: Low, Medium and High variation are introduced for classify 13 products into groups. Our analysis found that DeepAR is suitable for medium and high variations, while the low group can use any methods. With this approach, the case can gain benefit of better fill-rate performance.

최근 멧돼지의 개체수 및 농작물 피해 증가로 인하여 사회적 문제를 야기 시키고 있다. 국내 멧돼지에 대한 연구는 미미하여 향후 효과적인 멧돼지 관리를 위해서는 종에 대한 생태적 연구가 필요하다. 본 연구는 2012년 5월부터 12월까지 경남 거창군 일대에서 유해야생동물 포획을 통해 수집된 멧돼지 위 내용물(n=79) 분석을 통하여 식이습성 구명 및 선호 농작물을 파학하기 위해 수행되었다. 연구 결과 멧돼지는 주로 식물성 먹이를 섭식하며, 계절별로 유의한 차이를 나타냈다. 식물성 먹이는 잎-줄기가 83.5%로 가장 높은 출현율 보였으며, 농작물을 포함한 식물성 먹이는 건중량의 93.5%을 차지하였다. 무척추동물의 발견 빈도는 높았으나 빠르게 소화되는 특성으로 인하여 건중량은 낮게 나타났다. 식이농작물로는 밤, 벼, 사과 등이 선호하는 농작물로 나타났다. 수확기 농작물은 멧돼지가 야생 먹이보다 선호하여 의도적으로 섭식하는 것으로 판단된다. 지렁이는 총 수집된 위에서 50%의 출현율을 보였으며, 섭식 마릿수는 여름에 가장 높고, 겨울에 낮은 것으로 나타났다. 멧돼지는 전형적인 잡식성의 성향을 보이며, 시기에 따라 섭식하는 식이물이 다른 것으로 나타났다. 향후 멧돼지에 의한 농작물 피해를 줄이기 위해서는 밤나무림에 인접한 논과 사과 과수원의 우선적인 피해방지가 필요할 것으로 판단된다.

우리나라 식중독 발생 중에 중요한 원인이 되고 있는 황색포도상구균에 대해 초밥, 김밥, 식육 제품, 크림이 포함된 빵, 케이크 류, 냉면의 다양한 식품 종류에서 평균적으로 매년 5.3% 분리율을 보였으며 가열 과정을 거친 식품에서도 황색포도상구균이 완전히 사멸하지 않고 남아 있음을 알 수 있었다. 또한 유통 과정 및 판매과정이 식품 오염의 매우 중요한 원인이 되므로 냉장을 유지하는 유통 판매과정이 필요하며 소비자도 식품을 구매하고는 바로 섭취를 하거나 섭취하기 전 까지는 냉장 유통을 유지하여야 한다. 황색포도상구균의 한국 식품위생법 기준치 100 cfu/g 이상으로 검출된 시료는 김밥이 1.5%, 냉면이 1.5%, 초밥이 0.5%이고 평균 균수는 냉면이 7,682 cfu/g로 가장 높았다. 초기에 균에 의해 오염된 식품은 냉장 유통 과정을 거치지 않는다면 오염균이 급격하게 증식되어 식중독을 유발할 가능성이 매우 높으므로 초기 오염에 대한 철저한 관리가 요구되어진다. 황색포도상구균은 온도에 영향을 받으며 계절별로 여름철에 황색포도상구균의 오염이 높았으나 상대적으로 관리가 소홀해지는 겨울철에도 주의를 요한다. 식품에서 황색포도상구균은 장독소 SEA가 표현형, 유전형 우점형 이였으며 총 150주 (33.1%)에서 장독소 유전자가 검출되었으며 sea=sei, seh 순으로 검출되었다. 식품별로는 독소 유전자 유형이 다양하게 검출되었으며 특히 tst 유전자가 10주(3.6%) 검출되었다. SED 독소는 표현형과 유전형이 일치 하지 않았다(p>0.05). 새로운 독소들에 대한 PCR 법에 의한 독소 유전자 검출로 분리주를 구별은 신뢰할 수 있었다. 최종적으로 우리나라 식품에서 분리된 황색포도상구균의 특징을 연구를 통해서 향후 식중독 발생 예방 방지를 위해서 사용할 수 있는 기초 자료를 제공하고자 하였다.
