BACKGROUND/OBJECTIVES: The prevalence of atopic dermatitis in infants is increasing worldwide. However, the nutrient intake status of infants with atopic dermatitis has not been studied properly. This study was conducted to compare the nutrient intake status of infants in the weaning period with atopic dermatitis by feeding type. MATERIALS/METHODS: Feeding types, nutrient intake status and growth status of 98 infants with atopic dermatitis from age 6 to 12 months were investigated. Feeding types were surveyed using questionnaires, and daily intakes were recorded by mothers using the 24-hour recall method. Growth and iron status were also measured. RESULTS: The result showed that breastfed infants consumed less energy and 13 nutrients compared to formula-fed or mixed-fed infants (P < 0.001). The breastfed group showed a significantly lower intake rate to the Dietary Reference Intakes for Koreans than the other two groups (P < 0.001). In addition, they consumed less than 75% of the recommended intakes in all nutrients, except for protein and vitamin A, and in particular, iron intake was very low, showing just 18.7% of the recommended intake. There was no significant difference in growth by feeding type, but breastfed infants showed a significantly higher rate of iron deficiency anemia (P < 0.001). CONCLUSIONS: Continuous management programs should be prepared for breastfed infants with atopic dermatitis, who are in a period when rapid growth takes place and proper nutrient intake is essential.

This study examined the characteristics of the foodservice menu items offered at senior welfare centers to provide information on Korean senior menu development. A total of 514 lunch menu items were collected from 27 senior welfare centers in April, July, October and January. The most frequently served staple foods, soups, and side dishes were multi-grain rice, seaweed soup, Bulgogi, Kimchi, and liquid yogurt. The proportions of carbohydrate, protein, and lipids of total energy serving of senior welfare centers were 59.8%: 16.7%: and 22.8%, respectively. The nutrients served at less than 40% of the Recommended Nutrient Intake (RNI) and Adequate Intake (AI) of Dietary Reference Intakes for Koreans (KDRIs) were chloride (1.0%), vitamin D (1.3%), biotin (1.7%), magnessium (4.5%), Iodine (7.5%), pantothenic acid (8.0%), vitamin E (12.5%), vitamin $B_6$ (20.0~21.4%), vitamin K (21.1~24.3%), and water (35.7~39.7%). The nutrients served in excess of the daily intake goal and RNI were iron (98.9~127.1%), sodium (104.9%), and copper (1,100.0%).

This study investigates the relationship of smoking on daily intake of nutrients and snacks in the Chungnam and Daejeon high school students. Up to date scientific nutrition education and counseling programs in the regular school system is needed for a professional nutrition education teacher. The primary objective of this study was to provide useful information to nutrition education teachers. A survey was conducted with 400 high school students in the Chungnam and Daejeon areas. 381 out of 400 questionnaires were analyzed with SPSS 12.0K. The subjects were composed of 49.8% male, 50.1% female and 40.9% regular high school students, 59.1% business high school students and smokers 43.1%, non-smokers 56.9%. 43.4% of smokers had been smoking since middle school. On analysis of daily nutrient intakes, 16 out of 19 nutrients except animal calcium, Vitamin A and Vitamin C were much more consumed by the smoking group than the non-smoking group non-significantly. Especially vegetable fat and Vitamin E were higher in the smoking group than the non-smoking group (p<0.05). The intake ratio of carbohydrates: protein: fat was similar in the two groups (smoking group 55:15:29, nonsmoking group 56:15:28). Intakes of Vitamin B1 and potassium in comparison with the Korean dietary reference intakes(KDRI) were under 50% in both groups. However, sodium was taken over 200% compared to KDRI in both groups. Intakes of Vitamin C in the smoking group were as low as 76.5% in comparison to KDRI. Smokers need to increase the intakes of Vitamin C considering that smokers need to intake Vitamin C two times than non-smokers. Nutrient intakes from snacks in the smoking group were higher than the non-smoking group. Nutrients that originated from snacks which took over 20% among daily nutrient intakes were 12 nutrients(energy, fat, carbohydrate, calcium, P, Fe, K, Vitamin $B_1$, Vitamin $B_2$, Vitamin C, Vitamin E, dietary fiber) in the smoking group compared to 7 nutrients(energy, vegetable protein, fat, carbohydrate, calcium, Vitamin $B_2$, Vitamin C) in the non-smoking group. The smoking group was significantly paying more money for snacks each month than the non-smoking group was(p<0.01). Periods of consumption were irregular in the smoking group(p<0.05) and the smoking group was used to taking snacks in the morning compared to the non-smoking group. The smoking group preferred sweets and high calorie food over other snacks in comparison of the non-smoking group. The nonsmoking group had better eating habits than the smoking group.

Objective : To get a better understanding of obesity and etiological factors of obesity among school children. Methods : We have conducted a questionnaire survey of 4542 (2395male and 2147female) age from 7-15 in Shanghai School District to study their 24h nutrition intakes ; we have asked all our survey participating students to take a physical exam and body mass index measurement to determine the morbidity of obesity. Common statistic method was used in analyzing the data. Results : The result shows an over all morbidity (boys and girls) of $12.3\%$ among the students we have studied. Our research shows that boys have a higher rate of morbidity of obesity $17.1\%$ vs. $7.0\%$ for girls. The morbidity for boys starts under age 10, reaches the peak at age 10 ($24.3\%$), then declines after age 11 ; as for girls the morbidity starts at under age 9, reaches the peak at 9, and then declines after 10. Our study also indicates that the daily nutrition intake of protein, fat and carbohydrate by the students have satisfied Chinese Dietary Reference Intakes (DRIs), while the daily intakes of calcium, iron, zinc, and vitamin C are below the $80\%$ of the DRIs suggested value. For students who are obese, our study shows that their average daily intakes of calories and protein have reached $90\%$ of the suggested value by the RNI while the intakes of calcium, iron, and zinc are far below standards. Furthermore, our research shows that the obese students usually intake more calories, proteins and vitamin $B_1$, but less for iron and calcium compared to the normal students. Some other factors such as the education and occupation of the parents, especially the mother, the family history of obesity and the eating habits are important factors that should be closely watched. Conclusion : The morbidity of obesity among boys is higher than girls. Obesity is closely related to the family history, the diet habits and the life styles.

This study investigated the status and analyzed of stray dogs, stray cats admitted to the Jeju Animal Shelter during the year of 2015 to 2019, and the infection rates of specific diseases for abandoned dogs. In addition, in 2017 to 2019, the collected intake and outcome data were reviewed to analyze shelter capacity in terms of housing capacity (monthly daily average intake, required holding capacity, and adoption-driven capacity), staff capacity (staff hours required for daily care). Out of 24,557 dogs admitted to the shelter, owners of 1,808 dogs (7.4%) visited the shelter and found their lost dogs, while 3,612 dogs (14.7%) were adopted to new families. However, the number of puppies that were euthanized was the highest at 12,266 (49.9%), and 6,876 (28%) died either death from disease or natural causes because they were detained in shelters. The monthly daily average (MDA), which is one of the indicators for efficient population management of Jeju Animal Shelter, was found to be 17.4 for abandoned dogs and 1.7 for abandoned cats. Seasonal variations were observed for MDA, RHC, MDA adoptions, ADC, and RSDC, indicating that various strategies are needed for shelter management. This study was performed to analyze and interpret meaningful statistics for improving the efficiency of animal shelters in Jeju. However, inconsistent collection of animal statistics limited data compilation. Creation of a basic animal statistics matrix with reference to well-designed matrices from recognized professional animal shelters is essential.

Objectives: According to preceding studies, many people with mental disability have unbalanced dietary habits or excessive intake of calories. Most of them are overweight or obese due to lack of self-control for food consumption, swallowing with inadequate chewing and physical inactivity. Therefore, this study aimed to assess the nutritional intake, including carotenoid, in mentally disabled people and find out a possible solution for nutritional improvement. Methods: People with intellectual disability (N=28), emotional disability (N=44) participated in this study. The disorder grades were from I to III and ages were between 20 and 65 years. Assessments included anthropometry, daily intake of nutrients, including carotenoid, ROMA III questionnaire for assessing bowel movement. Results: The average BMI of intellectually disabled people and emotionally disabled people was in the range of overweight and obesity respectively ($23.7{\pm}6.3kg/m^2$, $25.8{\pm}4.1kg/m^2$). Overall, the frequencies of vegetable and dairy product intakes were lower in this population. When compared with Recommended Nutrient Intake (RNI) from Dietary Reference Intakes for Koreans 2010, the intakes of vitamin $B_1$, vitamin $B_2$ and calcium were insufficient in both groups. Also, lycopene intakes of carotenoid were low, compared with traditional Korean diet of the non-disabled people from the second year 2008 of the 4th National Health and Nutrition Survey. In addition, emotionally disabled people also had lower intake of cryptoxanthin. Conclusions: The mentally disabled people in this study showed lower intakes of vitamin $B_1$, vitamin $B_2$, calcium and carotenoids. Based on these findings, we recommend that it is important to encourage mentally disabled people to consume sufficient amounts of such nutrients in order to promote nutritional status.

Objective: Better feed efficiency can be achieved by selecting rabbit genotypes with lower residual feed intake (RFI) under high ambient temperatures. Methods: Two genotypes of rabbits (Jabali, Saudi local breed and imported, Spanish V-line) were used to derive RFI and to investigate the relationship between RFI and productive traits. In total, 250 animals (125 each) were housed in individual wire mesh cages in a semi-closed rabbitry. Growth performance, feed criteria, carcass evaluation, biochemical blood analysis, and immune responses were determined. Results: Superiority in growth performance, feed efficiency, carcass characteristics, and cellular immunity was recorded in the Jabali breed compared to the V-line genotype. According to regression analysis, a significant effect of daily body weight gain was found, upon computing the expected feed intake in both genotypes. Moreover, mid-body weight^0.75 had a significant effect only in the Jabali breed. Positive correlation coefficients between RFI and dry matter feed intake or feed conversion ratio were found. The same trend in this relationship between RFI and productive traits was observed in some cases for both genotypes. An opposite trend in correlations was observed in the studied genotypes for some traits. Conclusion: The results suggest that the relationship between RFI and productive traits must be taken into consideration in rabbit breeding programs under the prevailing environment. However, further studies are required to investigate the effect of rabbit genotype and environmental factors on computing RFI.

콜린은 세포막의 구조적 완전성, 메틸 대사, 아세틸콜린과 같은 신경전달물질 합성, 세포막 (인지질, phospholipids) 투과 신호전달, 지질 및 콜레스테롤 운반과 대사 등에 있어서 복합적으로 작용하고 있는 중요한 영양 성분이다. 콜린은 체내 합성이 가능하지만 요구량을 만족시키기에 불충분하므로 식사를 통해 섭취해야 한다. 미국/캐나다, 호주/뉴질랜드, 유럽, 중국, 대만 등에서는 콜린 충분섭취량과 상한섭취량이 제정되었으나, 일본은 콜린 데이터베이스가 구축되어 있지 않다는 이유로 콜린 Dietary Reference Intakes (DRI) 제정을 고려하고 있지 않다. 우리나라에서도 2020년 Dietary Reference Intakes for Koreans (KDRI) 제·개정 연구에서 콜린의 제정 여부를 검토하였으나 여전히 우리나라 식품을 대상으로 한 콜린 데이터베이스 구축 연구나 한국인을 대상으로 한 콜린 섭취량 조사 등의 연구가 전혀 이루어지지 않고 있어서 콜린 섭취기준의 제정은 어려운 것으로 판단하였다. 다만 2020년 DRI 개·제정을 위한 준비 작업의 일환으로 콜린 섭취량과 질병발생 가능성을 검증하기 위해 1949년부터 최근까지 보고된 문헌검색, 평가 및 문헌요약 작업을 통해 차후 콜린 DRI 제정을 위한 근거를 마련한 것은 본 사업의 성과라고 볼 수 있을 것이다. 인간을 대상으로 한 RCT, 코호트연구, 환자-대조군 연구 및 단면적 관찰 연구를 통해 충분한 양 (400-500 mg/day)의 콜린섭취는 간기능 손상 (지방간), 신경관손상, 심혈관질환 및 유방암 예방의 효과 및 인지기능 개선과 관계가 있는 것으로 판단되는 반면, 높은 수준의 콜린 섭취가 오히려 전립선암과 상관관계가 있다는 부정적인 연구결과도 있었다. 현재로서는 콜린 섭취와 건강결과와의 상관성을 결론짓기에는 연구결과들이 일관성이 부족하고 매우 제한적이고 더욱이 한국인을 대상으로 한 콜린 섭취와 건강결과와의 관련성을 조사한 논문은 전무한 실정이므로 콜린 DRI 제정을 위해서는 한국인을 대상으로 한 충분한 임상실험 결과가 뒷받침되어야 할 것이다.
