BACKGROUND/OBJECTIVES: This study examined socio-economic differences in diverse food consumption among children 6-23 months of age in South Asia and Southeast Asian countries. SUBJECTS/METHODS: Data from Demographic and Health Surveys in four countries in South Asia (n = 15,749) and four countries in Southeast Asia (n = 10,789) were used. Survey-design adjusted proportions were estimated for the following 10 food items: grains, legumes, dark green leafy vegetables (DGLV), vitamin A-rich fruits, vitamin A-rich vegetables, other fruits and vegetables (OFV), fish, meat, dairy, and eggs. An equity gap was defined as an arithmetic difference in the proportion of each food item consumed in the past 24-hours between the wealthiest and lowest quintiles and between rural and urban areas, denoted by percentage points (pp). RESULTS: The consumption of most of the 10 food items was higher in the wealthiest quintiles and urban areas across eight countries. The size of equity gaps was greater in Southeast Asia than in South Asia, particularly for vitamin A-rich fruits (3.3-30.0 pp vs. 0.3-19.6 pp), vitamin A-rich vegetables (12.1-26.7 pp vs. 2.4-5.9 pp), meat (17.7-33.4 pp vs. 3.4-13.4 pp), and dairy (14.7-32.5 pp vs. 3.3-11.4 pp). However, the size of equity gap in egg consumption was greater in Southeast Asia than South Asia (11.2-19.8 pp vs. 11.0-26.7 pp). Relatively narrower gaps were seen in the consumption of grains (0.3-12.9 pp), DGLV (0.6-12.4 pp), and fish (0.1-16.8 pp) across all countries. CONCLUSIONS: Equity gaps in food consumption differed by socio-economic status and region. Reducing equity gaps in nutrient-rich foods and utilizing regionally available food resources may increase child dietary quality.

The objectives of this study were to determine the recognition of food waste, school lunch leftovers and satisfaction toward school lunch in middle school students in Seoul. Four hundred students were surveyed beginning April, 2007. The results are summarized as follows. The primary means in which students learned about environmental pollution were 'video media' (54.7% males, 39.2% females) and 'by teachers' (23.2% males, 33.0% females). The primary effects on food habits after participating in the school lunch program were 'having a balanced diet' (23.3%) in the females, and 'decreased intake of junk food' (24.9%) in the males. The serving sizes for cooked rice, soup, and meat were higher in the females (3.46, 3.46, and 2,91, respectively) than the males (3.18, 3.29, and 2.73, respectively). The primary school lunch leftovers for one week were cooked rice (4.55), meat (4.35), kimchi (3.84), fish (3.60), vegetables (3.38), and soup (3.08). Importance-performance analysis of the school lunch meal indicated that good taste had high importance, but low performance. Nutritional balance, food safety, cleanliness of tableware and supplies, clean uniforms of employees, and cleanliness of the dining area had both high importance and performance.

The purpose of this study is to evaluate the creation techniques of artificial wetland, one of biotopes developed to promote biodiversity in urban areas, and to look for improvement steps. Specifically, artificial wetland creation techniques were categorized into living environment and living creature classification. Being living conditions for creations, habitat environment was reviewed with a focus on water and soil environments. Living creatures were classified into plants, insects, fish, and birds. The evaluation of creation techniques was done in post-construction evaluation while considering the creation of habitats for living creatures. Intervention by users, changes in living environment and living species, and relevance of creation techniques were reviewed. Key results of this study are as follows. (1) Water environment for the living environment of creatures provides a suitable environment conditions for the living of creatures through a process easing the use of piped water. Various water depths and embankment appear to have a positive impact on the living of aquatic life. In particular, embankment covered in soil naturally played an important role as a place for the activities of aquatic insects and young fish as well as the growth of aquatic plants. (2) Various aquatic and ground plants to promote insect-diversity, shallow water, and old-tree logs had contributed greatly in increasing the types and number of insects. Aquatic insects. Aquatic insects were seen much particularly in areas where aquatic plants are rich but water is shallow than any other areas. (3) A space piled with stone to provide habitats for fish was not much used. However, it was observed that fish used embankment built with natural stones and embankment using logs in areas where water is deep. In addition, it was confirmed that 1,500 fish that had been released propagated using various depths and places for birth. (4) It was analyzed that techniques (creation of island, log setting, and creation of man-made bird nests) to provide habitats and to attract birds are not serving their roles. In such a case, it is believed that species had not increased due to the smallness as well as isolated features of the area. Based on theoretical review, they are judged to be areas that are likely to be used when a greater variety of birds is introduced. It is judged that attracting and keeping more birds at the site, such spaces need to be linked systematically in the future in terms of building eco-network while ensuring an adequate living areas. (5) In the study areas, users intervened greatly. As a result, a blockage was created preventing the normal growth of plants and non-indigenous plants were introduced. In order to limit the intervention by users, setting enough buffer zones, and environment education programs were urgently required. D/H=1>Hyangkyo> houses on the river>temples>lecture halls.

This study has shown the screening of anti-bacterial activity of three Indian medicinal plant choloroform : methanol (50:50) solvent leaf extracts (i.e. Azadirachta indica, Ocimum sanctum, and Curcuma longa) with different concentrations (10, 5, 2.5, 1.25, 0.625, 0.312, and 0.156 mg/ml) under in vitro conditions against fish pathogenic bacteria, Aeromonas hydrophila, Streptococcus iniae, Vibrio harveyi, V. anguillarum, and Edwardsiella tarda isolated from olive flounder farms, Jeju Island, South Korea. The anti-microbial activity of the A. indica and O. sanctum extracts yielded the zones of growth inhibition (ZI) was 3 and 1mm against A. hydrophila at concentration of 0.156 mg/ml when compared to that of tetracycline standard (3 mm). At highest concentration (10 mg/ml) of A. indica, O. sanctum, and C. longa, high inhibition was 9, 7, and 6 mm when compared to that of tetracycline (11 mm) against A. hydrophila. The minimum inhibitory concentration (MIC) of A. indica, O. sanctum, and C. longa at 0.156 mg/ml that yield 9, 10, and 13 CFU/ml for A. hydrophila, 16, 22, and 25 CFU/ml for S. iniae and 18, 22, and 23 CFU/ml for E. tarda compared to the tetracycline. At highest concentration (10 mg/ml) of the three extracts was better inhibiting the growth of A. hydrophila, S. iniae and E. tarda. A. indica, O. sanctum, and C. longa were determined to the potential antioxidant activityon the basis of their scavenging activity of the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical. A. indica extract was 0.625 mg/ml which indicated that the strong anti-oxidant activity. However, O. sanctum and C. longa extracts showed weak anti-oxidant activity at this concentration. Hence, in vitro assay among the pathogens, A. hydropila is better inhibitory activity of the extracts. It is evident that the Indian medicinal plants extracts were subjected to its effectiveness against A. hydrophila, S. iniae, and E.tarda at low concentrations. The obtained results in the present study suggested that the Indian plant extracts is a prevention tools for Korean olive flounder aquaculture pathogens and its need further advance investigation.

This study was performed to determine the dietary risk factors associated with hypertension. The hypertensive group were composed of 112 hypertensive patients (male 53, female 59) who first visited the hypertension clinic and had been diagnosed as having primary hypertension ($SBP{\ge}140mmHg\;or\;DBP{\ge}90mmHg$). The regular visitors or the subjects on special diets or medical therapies were excluded. The normal group consisted of as subjects (male 41, female 54) matched with age and socioeconomic levels. The subjects having higher intakes (above the 75 percentile) in energy, protein, iron, vitamin A or C showed significantly higher hypertension risk estimated with odds ratio after the covariance factors (age, sex and BMI) were adjusted. More than 2400 mg of sodium (6 g of salt) intake was associated with significantly higher risk of hypertension (odds ratio: 1.773, CI: 1.014-3.014 for $SBP{\ge}140mmHg$; odds ratio: 2.373, CI: 1.359-4.215 for $DBP{\ge}90mmHg$). Hypertensive group showed significantly increased intakes of vegetables and fish and shell fish compared to the normal group. When the vegetable intakes were classified into Kimchi, fresh vegetables and cooked vegetables with seasoning, the hypertensive group was observed as having higher intakes of Kimchi and cooked vegetables with seasoning. The intakes of highest quartile for vegetables (${\ge}327g/day$) (odds ratio: 3.164, CI: 1.740-5.752), fish and their products (${\ge}102g/day$) (odds ratio: 2.756, CI: 1.486-5.109), grains(${\ge}311g/day$) (odds ratio 2.393, CI: 1.186-4.832), meats and their product (${\ge}106g$) (odds ratio: 2.210, CI: 1.225 - 3.987) compared to the lower were significantly associated with the higher risk of hypertension estimated with DBP (${\ge}90mmHg$) after covariance factors were adjusted. In conclusion, our findings confirm that higher intake of energy or sodium are associated with the increased risk of hypertension. Because increased intake of vegetable or fish was associated with the higher risk of hypertension, in contrast with the finding of western countries, choosing or preparation of vegetables or fish with reduced salt is recommended.

This study was undertaken to identify factors affecting school food waste generation using a questionnaire. The subjects were 254 high school students (male; 156, female; 98) in Sacheon, Gyeongnam divided into three groups of low (${\leq}1/week$), moderate (2~3/week), and high (${\geq}4/week$) according to the frequencies of food waste. The questionnaires consisted of general characteristics, anthropometric values, dietary habits, health-related behaviors, self-perceptions of food waste, snacking patterns, and nutrition knowledge. The main reasons behind food waste were 'too much food' in the low (20.9%) and moderate (32.2%) groups, and 'no appetite' in the high group (p<0.01). The main types of food waste were rice (44.2%) > fish (18.6%) > vegetables (14.0%) in the low group, rice (54.2%) > Kimchi/vegetables (15.3%) in the moderate group, rice (56.0%) > vegetables (20.0%) > Kimchi (16.0%) in the high group (p<0.01). School food waste was significantly affected by age, gender, monthly allowance, school grade, weight, BMI, regularity of meals, time of meals, type of breakfast, starting age of smoking, and cost for snacking.
