The present study was performed to evaluate food behavior and nutritional status of children in a community child center using nutrition quotient according to age and growth index of children. The number of subjects enrolled in this study was 152 including 73 boys and 79 girls. Participants consisted of children from 5 to 12 years old, who visited a community child center in the area. Growth index was assessed through body mass index by height and weight and examined according to age. Subjects were divided into underweight, normal weight, overweight and obese according to questionnaire, which consisted of five categories including balance, diversity, moderation, regularity and practice, were analyzed by SPSS statistical program. Current results show significant differences in the diversity and regularity (p<0.05, p<0.001, respectively). Additionally, four items in the form of 10 questions showed significant differences related to habits of sodium-related food intake. This study design will be a useful tool in the evaluation of food behavior and nutritional status of preschoolers or elementary school children in community child centers, together with food frequency questionnaires related with sodium food intake.

Porphyra yezoensis is a red algal species in the genus Porphyra. The phenetics and genetic diversity of four populations of P. yezoensis in Korea were reconstructed using random amplified polymorphic DNA (RAPD) markers. Overall, 55 fragments were generated among the tested P. yezoensis array with 20 OPERON primers. A total of 30(54.5%) of these bands were polymorphic. The OPA-18-02 band was amplified in the samples of Nakdong population and absent in them of other three populations. The OPA-20-02 band was only amplified in the Seocheon population. Both bands exhibited distinctive patterns in specific populations. The effective number of alleles per locus (Ae) ranged from 1.161 to 1.293 with a mean of 1.366. The Seocheon population had a high expected diversity (0.163). The Nakdong population was an isolated endemic and intertidal zone. Thus the narrow distributed Nakdong population had a low expected diversity (0.092). Shannon's index of phenotypic diversity (I) of the Seocheon population (0.238) was the highest among all populations. Total genetic diversity ($H_T$) varied between 0.132 for OPA-02 and 0.420 for OPA-19. The interlocus variation of genetic diversity ($H_S$) was 0.059 for OPA-18 and 0.339 for OPA-19. On a per locus basis, the proportion of total genetic variation due to differences among populations ($G_{ST}$) ranged from 0.012 for OPA-11 to 0.762 for OPA-18 with a mean of 0.415, indicating that 42% of the total variation was found among these populations. In an assessment of the proportion of diversity present within this species, 58.5% (100%-41.5%) of genetic variation resided within the populations studied. The Nm was estimated to be low (0.705).

A diet rich in proinflammatory components and inflammation are suggested to be significant risk factors for multiple sclerosis (MS). This study aimed to investigate the association between the risk of MS and the inflammatory potential of an individual's diet and dietary diversity through pro-inflammatory/anti-inflammatory food intake score (PAIFIS) and dietary diversity score (DDS). In a hospital-based case-control study, 397 participants, including 197 patients with MS and 200 healthy participants aged over 18 years, were evaluated. The history of smoking, dietary intake, and anthropometric characteristics, including body mass index, waist circumference, total body fat, and fat-free mass were assessed. A validated 160-item semiquantitative food frequency questionnaire was used to calculate the PAIFIS and DDS scores. The mean age of the participants was 32.45 ± 8.66 years, and most were females (274, 79.4%). The PAIFIS score was significantly higher among MS patients than healthy participants (p = 0.001). Between PAIFIS and DDS, only PAFIS was significantly related to MS risk (odds ratio, 1.002; 95% confidence interval, 1.001-1.004; p = 0.001). PAIFIS, as an index of dietary inflammation, can predict MS. Further studies are needed to document these findings.

BACKGOUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin $B_6$ and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

Purpose: This study was conducted for analysis of menu pattern and food diversity of snack menus of child care centers in order to provide preliminary data for establishment of related guidelines for snack menus for child care centers. Methods: Data from 630 snack menus (350 for morning snacks and 280 for afternoon snacks) of March, 2013 from 14 Child Care Information Centers in Seoul provided for child care centers were analyzed. In addition, the menu pattern and food diversity of morning snack menus were compared with those of afternoon snack menus. Results: Differences in menu pattern and food diversity were observed between morning and afternoon snack menus. The majority of snack menus (66.8%) included two menu items and the numbers of menu items of afternoon snack menus were significantly larger than those of morning snack menus. The percentages of "Grains (G)" and "Grains (G) + Milk (D)" patterns were higher in snack menu (G: 18.9%, G+D: 17.1%). Approximately one third of snack menus were composed of only one food group. In addition, 45.6 % of all snack menus comprised milk and only 23.0% included fruits. Conclusion: These results demonstrated the need for improvement in food composition and diversity of snack menus provided by Child Care Information Centers for child care centers. Therefore, to ensure children's intake of nutritionally balanced snacks, it will be necessary to establish more detailed guidelines for the menu pattern and food composition in snack menus for child care centers.

Genetic diversity of Magra - a lustrous carpet wool breed of India, was investigated by means of 25 ovine microsatellite markers proposed by the Food and Agriculture Organization and the International Society for Animal Genetics (FAO-ISAG). All used microsatellites amplified well and exhibited polymorphisms. A wide range of genetic variability was observed as allele number from 3 (BM6506, OarCP20) to 10 (CSSM31), observed heterozygosity from 0.200 (BM6506) to 0.947 (OarHH35), expected heterozygosity from 0.368 (CSSM47) to 0.864 (BM1314) and Polymorphism Information Content (PIC) from 0.347 (CSSM47) to 0.849 (BM1314). This supported the utility of these microsatellite loci in the measurement of genetic diversity indices in Indian sheep too. Various average genetic variability measures viz., allele diversity (5.7), observed heterozygosity (0.597), expected heterozygosity (0.694) and mean PIC (0.648) values showed high genetic variability despite accumulated inbreeding as reflected by the high average inbreeding coefficient ($F_{IS}=0.159$) due to the unequal sex ratio of the breeding animals.

Microorganism are centIal core to biosphere sm1ainablity and biogeochemical cycles on this earth. Most of food, medical and pabamceutical new materials through biotechnology are derived from many kinds of microorganisms. Microorganisms are important resources of biotechnology. Beside these, micorbial diversity is key to explore the frontiers of knowledge about the strategies and limits of life. Through the micorotganisms, we can monitor the environmental changes and conditions. Moreover, the microorganismsms play a role in conservation and restoration of higher plants and animals. And we can get a lot of ecological, evolutionary knowledges from microbial models. In spite of these importances, the microbial diversity is not properly evaluted because of their unculturablity. Only 0.001 - 3 % of total bacteria in natural habitats are cultumble and the rest are viable but uncultumble. Only 3,100 species are listed up in the Bergey's Manual. Considering the symbisis and estimated numbers of insect are more than 800,000, the symbiotic microorganisms are about 1,000,000 species. Recently, by using the genetic and molecular technics, the microbial diversity is now unveiled. In this symposium, the genetic, species and ecological diversity will be given. given.
