This study was aimed to investigate management conditions and dietitians' perception for improvement of school milk programs. Using an online sampling method, collected data from 1,723 dietitians nationwide were analyzed. The results show that 44.4% of respondents carried out the cyclic school milk program, providing various types of dairy products either weekly or monthly. Further, 80.3% of respondents answered that preference survey results were a determining factor in their choice of school milk provider, and 55.9% said that a school steering committee made the decision on relevant facts of the school milk program. For diversification of school milk type, 60.5% of respondents wanted to maintain the current system, and 39.5% answered that milk type needed to be diversified. The respondents preferred fermented milk products, functional milk, and processed milk, in order, if school milk type is diversified. To improve perception and knowledge about milk, 66.0% of respondents thought that nutrition education by a nutrition teacher would be the most effective, and parent's letters or a nutrition newsletter would be helpful. More than half of respondents (55.0%) disagreed with a merged program for school foodservice and milk.

OBJECTIVETo identify the antimicrobial resistance of commercial lactic acid bacteria present in microbial foods and drug additives by analyzing their isolated strains used for fermentation and probiotics.
METHODSAntimicrobial susceptibility of 41 screened isolates was tested with disc diffusion and E-test methods after species-level identification. Resistant strains were selected and examined for the presence of resistance genes by PCR.
RESULTSDistribution of resistance was found in different species. All isolates were susceptible to chloramphenicol, tetracycline, ampicillin, amoxicillin/clavulanic acid, cephalothin, and imipenem. In addition, isolates resistant to vancomycin, rifampicin, streptomycin, bacitracin, and erythromycin were detected, although the incidence of resistance to these antibiotics was relatively low. In contrast, most strains were resistant to ciprofloxacin, amikacin, trimethoprim/sulphamethoxazole, and gentamycin. The genes msrC, vanX, and dfrA were detected in strains of Enterococcus faecium, Lactobacillus plantarum, Streptococcus thermophilus, and Lactococcus lactis.
CONCLUSIONAntibiotic resistance is present in different species of probiotic strains, which poses a threat to food safety. Evaluation of the safety of lactic acid bacteria for human consumption should be guided by established criteria, guidelines and regulations.

OBJECTIVE: The main causes of spinal cord ischemia are a variety of vascular pathologies causing acute arterial occlusions. We investigated neuroprotective effects of kefir on spinal cord ischemia injury in rats. METHODS: Rats were divided into three groups : 1) sham operated control rats; 2) spinal cord ischemia group fed on a standard diet without kefir pretreatment; and 3) spinal cord ischemia group fed on a standard diet plus kefir. Spinal cord ischemia was performed by the infrarenal aorta cross-clamping model. The spinal cord was removed after the procedure. The biochemical and histopathological changes were observed within the samples. Functional assessment was performed for neurological deficit scores. RESULTS: The kefir group was compared with the ischemia group, a significant decrease in malondialdehyde levels was observed (p<0.05). Catalase and superoxide dismutase levels of the kefir group were significantly higher than ischemia group (p<0.05). In histopathological samples, the kefir group is compared with ischemia group, there was a significant decrease in numbers of dead and degenerated neurons (p<0.05). In immunohistochemical staining, hipoxia-inducible factor-1alpha and caspase 3 immunopositive neurons were significantly decreased in kefir group compared with ischemia group (p<0.05). The neurological deficit scores of kefir group were significantly higher than ischemia group at 24 h (p<0.05). CONCLUSION: Our study revealed that kefir pretreatment in spinal cord ischemia/reperfusion reduced oxidative stress and neuronal degeneration as a neuroprotective agent. Ultrastructural studies are required in order for kefir to be developed as a promising therapeutic agent to be utilized for human spinal cord ischemia in the future.

Candida guilliermondii is found in sea water, animal feces, buttermilk, and beer and has been isolated from human infections, mostly of cutaneous origin. It usually causes skin and soft tissue infections and has decreased susceptibility to fluconazole. Systemic infections occur mostly in immunocompromised patients. A 38-year-old female was admitted with a 4-day fever. Her medical and family histories were unremarkable, except for obesity. She had been taking diet pills for 3 months and had undergone injection therapy into her abdomen for lipolysis for 1 month. She did not respond to empirical antibiotics. A Candida species was isolated from blood cultures and identified as C. guilliermondii based on partial LSU rRNA gene sequence analyses. She was treated with amphotericin B, and recovered completely.

Probiotics have emerged as a potential treatment modality for numerous gastrointestinal disorders, including IBD. However, few probiotics have undergone appropriate preclinical screening in vivo. Kefir is considered a probiotic, benefiting the host through its effects in the intestinal tract. Despite numerous studies examining the action of probiotics on the host organism, few have analyzed the effects on intestinal environment. We assessed the protective effect of kefir for three weeks before inducing colitis with 2% dextran sodium sulfate for five days. The DSS loads were similar in all DSS treatment group. The results of the experiment are as follows. Food intake and FER of experimental groups were not significantly different each other, but water consumption tended to be higher in all DSS treatment groups as compared with the normal control. And visual inspection of feces revealed mild diarrhea in rat given 2% DSS. The anti-inflammatory activity of kefir was determined by myeloperoxidase activity during the DSS treatment, and there was no significant difference in any group. The levels of thiobarbituric acid reactive substances (TBARS) as a colonic lipid peroxidation were significantly lower in the kefir intake groups than in rats treated with 2% DSS alone. The DNA % in tail and tail moment values as a DNA damage level of the blood lymphocytes in kefir intake groups tended to be lower than 2% DSS treatment alone, especially tail lengths were significantly diminished. According to the colonic histopathological assay, there were a severe inflammation of lamina propria and submucosa and mild edema in mucosa and sub mucosa in DSS alone treated group. We found a slight regenerative change in kefir treatment groups. In our experiments, this means that ulcerative colitis related to oxidative injury might be prevented by kefir as a probiotic. Further studies of the potential benefits of kefir as a probiotic in inflammatory condition are encouraged.

6.Acceptability and adaptability of children with yogurt
Journal of Practical Medicine 2001;397(5):21-23
The study was conducted to evaluate the acceptability and the adaptability with a new food (yogurt) of young healthy children in community setting. Seventy-nine healthy children who were 6-24 months of old at baseline from a rural commune were selected to involve in this study. The children received 150 ml yogurt each day, six day a week for 13 weeks. The amount of yogurt consumed by children was recorded daily by health workers. In the first week, the 6 to 12, 13 to 18 and 19 to 24-month-old children consumed 68%, 65% and 84% serving portion, respectively. Age was the only factor that affected on the acceptability of the children (p<0.01). The young children adapted well with yogurt within 1-3 weeks. The older children adapted faster than the younger ones. The results showed that the acceptability and adaptability of the young children with new foods was high, although was slower in the younger children.

7.Evaluation of a Nutrition Education Program Designed to Reduce Sugar Intake in Preschool Children.
Journal of the Korean Dietetic Association 2016;22(3):179-192
The purpose of this study was to evaluate a nutrition education program designed to reduce sugar intake in preschool children. The nutritional knowledge, dietary attitude, dietary behavior, and food intake with a sweet taste in preschool children were tested before and after 4 weeks of nutrition education from March 8 to April 1, 2016. The preschool children were recruited in Dobong-gu, Seoul. The subjects were divided into two groups; educated (N=59) and non-educated group (N=40). Statistical analyseis were performed using SPSS 22. The nutritional knowledge about sweet tasting food was significantly increased (P<0.01) in the educated group and significantly decreased (P<0.01) in the non-educated group. The dietary attitude toward sweet tasting food was significantly decreased (P<0.05) in the educated group but not significantly changed in the non-educated group. The dietary behavior toward sweet tasting food was significantly decreased (P<0.05) in the educated group and significantly decreased (P<0.01) in the non-educated group. The major food sources of sugar intake were not significantly changed in either groups. The major food sources of sugar intake in the 5 years old children were yogurt products>sweetened breads>cookies/biscuits>chocolate>cereals>beverages>sweetened milk>sweet spicy chicken>Tteokbokki. Although there are some limitations in this study, due to the short length of the nutrition education and lack of active participation by the parents, the results suggest that effective nutrition education on sweet tasting food can bring about changes in nutritional knowledge as well as dietary attitude.

Journal of the Korean Dietetic Association 2016;22(3):163-178
This study was designed to examine the level of milk consumption and perception of the school milk programs among elementary, middle and high school students, which provides the information to improve the school milk program. Using a self-administered questionnaire survey, the data collected from 1,725 students nationwide were analyzed. The results showed that whole milk was the type of milk most frequently drunk by the students, although flavored milk and yogurt products were also highly preferred. When asked whether they wanted the school milk program or not, approximately 30% of the students in the schools presently participating in the school milk program and 50% of the students in the schools not participating the school milk program answered "yes". However, all of the respondents preferred to have a choice for the school milk program. The elementary school students showed a higher level of satisfaction with the school milk program than the middle and high school students. Especially, the level of satisfaction with the taste and flavor of the milk was the lowest among the various satisfaction items. However, the students were reported to believe that milk is highly nutritious and good for their health in the present study. Our results suggest that providing a choice of dairy products would improve the students' satisfaction with the school milk program, and that continuous education about the benefits of drinking milk would also encourage them to participate in the school milk program.

10.The Comparisons of Elementary School Children's Food Purchasing and Consumer Competency for a Healthier Diet by Their Attitude toward the Meal Management.
The Korean Journal of Nutrition 2008;41(4):353-364
In this study elementary school children's food purchasing and consumer competency for a healthier diet were compared by their attitude toward the meal management. The subjects were 779 sixth grade elementary school children (417 boys and 362 girls) in Busan. They were classified into three groups: 'High' was composed of 226 subjects who had more than the mean +1/2 SD of attitude toward the meal management; 'Medium' was composed of 343 subjects who had the mean +/-1/2 SD; and 'Low' was composed of 210 subjects who had the less than the mean -1/2 SD. The results were as follows. The high group had less pocket money than the low group, and thought that their allowances were adequate to their needs. They also had a habit of entering amounts into an account book. The children in the low group purchased mostly snacks without making or practicing a budget. The high group purchased yogurt, fruit, or bread as snacks more frequently than the low group. More children checked the nutrient facts on the package in high group than in the low group. There were no significant differences in the consumer's knowledge of a healthy diet among the groups; but there were significant differences in the consumer's skill, and the consumer's attitude toward a healthy diet among the groups. The high group had higher skills and more positive attitudes than the low group. This research suggests that education can elevate interest and can help develop more positive attitudes toward healthy diets among children. The education can help them to develop planned food purchasing habits, and improve their consumer competency for a healthy diet.
