This survey was carried out to study the food habit and several health indicators of 438 persons (male ; 179, female ; 259) aged over 60 years old living in a middle city, The results obtained were as follows. The food habit of male was better significantly than that of female, the eating frequencies of fruits, eggs, meats and fishes, and legumes of male were higher than those of female. The mean weights and heights of both male and female were low in comparison to the Korean standard, but the mean BMIs of both male and female showed normal range and the mean obesity rates of male and female were 3.5% and 8.2%, respectively, The mean hemoglobin content and hematocrit were 13.1g/100m1 and 39.8% in male, and 12.4g/100m1 and 37.8% in female, respectively, The anemia rate judged by the WHO level of hemoglobin content was 42.0% in male and 34.7% in female. The mean systolic and diastolic blood pressures of both male and female showed normal range; But the incidence of hypertension judged by the WHO level was 15. 6% in male and 16.7% in female. The subjects suffering from diseases were 78.2% in male and 86.7% in female. Common diseases were neuralgia, circulatory system diseases, respiratory system diseases, diabetes mellitus, and athritis. There were positive correlations between the score of food habit and body weight, height, hemoglobin content, and hematocrit. And there was a negative correlation between the food habit score and obesity rate. Systolic and diastolic blood pressures were correlated positively to skinfold thickness and the incidence of suffering from diseased.
We have analyzed the effect of planting site (elevation) and direction of fruiting on the frost damage (tolerance to transparent skin and blemishes) of persimmon (Diospyros kaki Thunb) 'Fuyu' fruit subjected to the early fall frost (November 2, 2012) in environment-friendly orchards of Changnyeong and Changwon (Gyeongsangnam-do Korea). In Changnyeong, the direction of fruiting showed a significant effect on the fruit weight and the fruit width (p<0.01), and the fruit firmness (p<0.05) while the planting site (elevation) did a highly significant effect on the fruit width and the frost damage (p<0.01), and fruit length (p<0.05). In particular, severe frost damage of fruit (15.2%) and leaves (about 90%) was observed in the plants located in the low elevation area of orchard. The damaged fruit had an transparent skin color and/or blemishes. In Changwon, there was no effect of the planting site and the direction of fruiting on the frost damage, and the fruit characteristics except the fruit width having been related to the planting site (p<0.05). So, the main effects for the fruit frost damage was a terrain factor around the orchards.

A growing number of healthy dietary ingredients in fruits and vegetables have been shown to exhibit diverse biological activities. Phloretin, a dihydrochalcone flavonoid that is abundant in apples and pears, has anti-inflammatory effects on ulcerative colitis (UC) mice. The gut microbiota and metabolism are closely related to each other due to the existence of the food-gut axis in the human colon. To investigate the interplay of faecal metabolites and the microbiota in UC mice after phloretin treatment, phloretin (60 mg/kg) was administered by gavage to ameliorate dextran sulfate sodium (DSS)-induced UC in mice. Gut microbes and faecal metabolite profiles were detected by high-throughput sequencing and liquid chromatography mass spectrometry (LC-MS) analysis, respectively. The correlations between gut microbes and their metabolites were evaluated by Spearman correlation coefficients. The results indicated that phloretin reshaped the disturbed faecal metabolite profile in UC mice and improved the metabolic pathways by balancing the composition of faecal metabolites such as norepinephrine, mesalazine, tyrosine, 5-acetyl-2,4-dimethyloxazole, and 6-acetyl-2,3-dihydro-2-(hydroxymethyl)-4(1H)-pyridinone. Correlation analysis identified the relations between the gut microbes and their metabolites. Proteus was negatively related to many faecal metabolites, such as norepinephrine, L-tyrosine, laccarin, dopamine glucuronide, and 5-acetyl-2,4-dimethyloxazole. The abundance of unidentified Bacteriodales_S24-7_group was positively related to ecgonine, 15-KETE and 6-acetyl-2,3-dihydro-2-(hydroxymethyl)-4(1H)-pyridinone. The abundance of Christensenellaceae_R-7_group was negatively related to the levels of 15-KETE and netilmicin. Stenotrophomonas and 15-KETE were negatively related, while Intestinimonas and alanyl-serine were positively related. In conclusion, phloretin treatment had positive impacts on faecal metabolites in UC mice, and the changes in faecal metabolites were closely related to the gut microbiota.

The purpose of this study was to investigate whether the activity of ginsenoside metabolites and the intestinal immunity antioxidant activity were remarkably improved by lactic acid bacteria fermentation by adding a small amount of ginsenoside to the complex extracts of fruits and vegetables. It was confirmed that the increase in intestinal immunity antioxidant activity due to synergistic effect was observed in the fruit-vegetable extract containing ginsenoside compared to the ginsenoside-only extract or the fruit-vegetable extract. Then, by adding ginsenosides by content, the concentration of ginsenosides that can obtain a synergistic effect according to the fermentation of lactic acid bacteria was determined. As a result, it was confirmed that a synergistic effect was exhibited when lactic acid bacteria were fermented and extracted by mixing ginsenosides in a mass ratio of 3 to 10% with respect to the mass of the fruit-vegetable mixture. As a result, when treated at a concentration of 200 ㎍/ml, the fruit-vegetable complex extract containing ginsenoside metabolites inhibited the generation of NO by about 60% compared to the complex extract containing no ginsenoside, The expression of IL-1β was suppressed by 63%, the expression of IL-6 by 69%, and the expression of TNF-α by 76%, confirming that the intestinal immune antioxidant properties were significantly improved.
The purpose of this study is to estimate the nutrient intakes and food habits among preschool children in Kyungjoo city. The subjects were 210 preschool children, aged 4 - 6 years. Measurements of the weight, height, chest circumference, and head circumference of the children were conducted. And general home environment and factors related to eating habits for preschool children were collected using a questionnaire that included information about family income, parents' education and occupations. The average weight-length index (WLI) for the subjects was $103.9\%$. Using the WLI, $20.0\%$ of the preschool children were underweight, $48.6\%$ were normal, $19.0\%$ were overweight, and $12.3\%$ were obese. On the R$\ddot{o}$hrer index, $13.8\%$ of the preschool children were underweight, $38.5\%$ were normal, and $47.7\%$ were over weight or obese. The average daily intake ($\%$ of RDA) of energy and each nutrient was 1323.5 kcal ($81.3\%$), Ca 484.3 mg ($80.7\%$), Fe 7.05 mg ($88.1\%$), vitamin A 420.0 RE ($105\%$), vitamin $B_{2}$ 0.76 mg ($95.0\%$), vitamin $B_{2}$ 0.87 mg ($87.0\%$), and vitamin C 53.1 mg ($106.2\%$) , respectively. In particular, older subjects had lower intake in RDA $%$ of calcium and iron. The energy intake ratio from snacks was much higher than the recommended level of the preschool children. With regard to frequency of regularity of breakfast, $1.9\%$ of preschool children skipped every morning and $7.6\%$ of the children skipped more than 5 per week. With regard to the intake frequency of vegetables, fruits, complex carbohydrates, and milk, $13.3\%$, $19.9\%$, $22.8\%$, and $41.8\%$ of the children ate more than 5 times per week. The eating habit score was positively correlated (r = 0.18, P < 0.05) with household income. This study suggests that nutrition education to increase fruit and vegetable consumption for preschool children should be emphasized. Also a nutrition education program is needed to enhance consuming calcium and iron intake for adequate growth.

While periodic marketing systems have lasted for more than hundreds of years in Korea, the weekly (periodic) markets have emerged since the latter half of the 1990s in the densely populated urban areas. In Jinju, weekly markets are opened on eight densely populated area: Ehyeon Wellga Apt.(Monday market), Gumsan Apt.(Tuesday market), Juyak Hanbo Apt.(Wednesday market), Chojeon Apt.(Thursday market), Manggyeong Hanbo Apt.(Thursday market), Pyeonggeo Dulmalhanbo Apt.(Friday market), Gajoa Jugonggreenville Apt.(Saturday market), and Gaho Apt.(Saturday). The merchants of Jinju's weekly markets can be classified into three groups as follows: the migrating specialized(full-time) merchants, who sell fruits, fish, and other daily necessities: the farmer part-time women merchants in the sixties or in the seventies, who sell the agricultural products that they themselves have grown around the rural areas; and the vendor merchants, who sell mostly dduk-bok-ki, eo-mug(odeng), and other fast food. The origin and persistence of periodic markets are explained in terms of the concepts of central place theory, the economic/comparative advantage of periodic markets, and the traditional organization of time and inertia.

The purpose of this study was to examine the characteristics of the dietary intake of Korean elderly according to chew-ing ability using data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted during 2007-2010. Among subjects aged 65 years and over, more than half, 54.3% of elderly people, were classified as the difficulty in chewing group (DC). The DC group had lower nutrients and food intakes than those of in the no difficulty in chewing group (NDC). Findings showed that subjects in the DC group consumed fewer foods, especially fruits and vegetables. In addition, the DC group had significantly lower intakes of pan-fried food, stir-fried food, braised food, and seasoned-cooked vegetables, which could not be easily cooked or chewed. On the other hand, the number of soups and stews included in the top 30 largely consumed dishes were higher in the DC group than in the NDC group. No difference in numbers of daily meal/snack intake was observed between the two groups, however, the DC group had lower numbers of side-dishes compared to the NDC group. Fewer side-dishes per meal could be related to lower intakes of nutrients in dietary quality. Findings of this study demonstrated that dietary intake was influenced by chewing ability of elderly Korean people. Therefore, study of factors affecting dietary intake such as convenient cooking methods to decrease cooking time and skills to extend preservation and storage time of foods will necessary. In addition, development of food products and new techniques of cooking considering health status, chewing, and swallowing ability is required for the elderly, followed by establishment of standards for senior-friendly food products.

This study analyzes the content of niacin, B1, and B2, which are among the water-soluble vitamin B group, in cultivars of the commonly consumed agricultural products of apples, peaches, nectarines and strawberries to compare content differences and to use results as base material for the Korean Food Composition Table. While the vitamin B1 content of apples according to different cultivars was found to be within the ranges of 0.063-0.208 mg/100g, and the content of vitamin B2 was found to be within the value ranges of 0.006-0.031 mg/100g, no niacin was found. The vitamin B1 content of peaches and nectarines according to different cultivars was found to be within the value ranges of 0.014-0.276 mg/100g, the content of vitamin B2 was found to be within he value ranges of 0.019-0.042 mg/100g, and niacin content was found to be within the value ranges of 0.298-1.096 mg/100g. The vitamin B1 content of strawberries according to cultivars was found to be within the value ranges of 0.112-0.394 mg/100g, the content of vitamin B2 was found to within the value ranges of 0.001-0.027 mg/100g, and niacin content was found to be within the value ranges of 0.388-0.809 mg/100g. Therefore, when nutrient composition analysis databases for the fruits of apples, peaches, and strawberries are constructed, cultivar factors must be put into consideration. In addition, differences can be found according to fruit harvest times, cultivation methods, and environmental factors, so related additional is needed.
This study was conducted to investigate the dietary habits and nutritional knowledge of 5th and 6th graders and the teachers' perception of dietary life education at the elementary schools in Chuncheon area. The children who had breakfast and supper everyday accounted for 54.1% and 80.3% each. Children consumed 'breads or confectioneries'(42.6%) and 'fruits or juices'(39.3) as snacks. Only 57.4% of the children had balanced diet. Only 59% of the children answered correctly at the nutritional knowledge test, and only 75% had good dietary behaviors. About 78% of the teachers had the experiences of dietary life education, and they taught it in class(38.9%) or at school lunchtime(35.2%). The teachers answered that the major nutrition problems of elementary students were bad eating habits(37.7%) and too much ingestion of fast or instant foods(36.2%). They also answered that dietary life education was necessary(79.7%) and should be started more earlier(87.0%). Ironically, about 49% of the teachers answered that dietary life education should be taught by dietitians even if the teacher who spent most of the time with their students is the best person for dietary life education at school. It should be done in children's daily life, especially for elementary school students. Therefore, teachers should recognize the importance and the specialty of dietary life education at the elementary schools.
Plants of Lycopersicon esculentum, containing various organic compounds, are known to develop idioblasts in their epidermis. Lycopersicon esculentum have long been investigated in many areas, but structural aspects of the epidermis of various organs have not been carried out in detail. Thus, the present study attempted to reveal the patterns of idioblast development, particularly those of the reproductive organs, in L. esculentum epidermis using scanning electron microscopy. The present study mainly focused on patterns of the stomata and trichome types. Two types of stomata were developed in the flowers and fruits: anomocytic stomata (stomata type I) were distributed normally throughout the epidermis, whereas actinocytic raised stomata (stomata type II) were found variously in different epidermal tissues. For the trichomes, both glandular and non-glandular types were developed in the epidermis. The former included peltate glandular trichomes having four head cells (trichome type I) and capitate multicellular glandular trichomes (trichome type II). The latter included non-glandular short trichomes (trichome type III) and considerably elongated trichomes with basal rosette cells (trichome type IV). In paticular, the raised stomata were well-developed in the peduncles and the peltate glandular trichomes were prominent in the sepal and ovary epidermis. Transmission electron microscopy on the ontogeny and ultrastructural differentiation of these idioblasts, associated with the current result, will aid us in better understanding of the structure and functional relationship in the epidermal differentriation of Lycopersicon esculentum.
