From the onset of puberty or during its progress, eating and health behaviors are important in establishing optimum growth and healthy fitness in middle school students. This study investigated the dietary and health behavior of first grade middle school students(male 260, female 255) selected from 3 middle schools in Suwon. Results were analyzed using the statistical program(SAS ver. 8.1). Usual dietary habits were scored by the Likert scale of 5 points and obtained the mean and standard deviation. Obtaining significant gender difference, chi-square and student t-test were also done. Daily breakfast intake was 70% of all students but some of them ate alone(27.3%). The amount of food intake was slightly less(34.8%) but sufficient food for dinner(53.2%). The purpose of each meal was solving hunger(57.4%). However, they want to change their current eating habits because of an unbalanced diet. Usual dietary habits were similar in gender, but 'apply nutrition knowledge' and 'consider food combination' were better in female students (p<0.01), 'regular meals' were higher in males(p<0.01). With respect to health behavior, the subjects went for daily walks for less than an hour(39.9%) and got 7-8 hours of sleep per day(33.8%). The amount of sleep was sufficient(22.6%) in males but in insufficient (33.8%) in female students(p<0.01). Weight control efforts for reducing(female 27.5% male 20.8%) and for increasing(male 10.6%) differed according to gender(p<0.01). As the result of the above analyses, the direction of nutrition education would be oriented to the nutrition knowledge and food combination applying to the diets of male students and regular meals for females. And also sleep dissatisfaction needs to be altered with taking care weight control trials.

The feeding habits of the Siniperca scherzeri were studied using 332 specimens collected by trammel net in the Soyang Lake of Han River, from April to November 2014. Of 332 specimens, 197 contained food and 135 were empty. The standard length of individuals used in this study ranged from 107 to 321 mm. Mandarin fish mainly consumed fishes and shrimps. The main food items of fishes and shrimps were Hypomesus nipponensis and Macrobrachium nipponense. The proportion of fishes in prey items increased with increasing mandarin fish length, however shrimps decreased with growth. The seasonal difference were apparent, fishes were taken mainly all the seasons except June, July and October. There were higher rates of fishes for food items in downstream areas than in the upper and middle areas of the Soyang Lake.

The feeding habits of the Glowbelly Acropoma japonicum were examined based on 849 specimens collected from the coastal waters of the South Sea of Korea. The total length (TL) of these specimens ranged from 2.6 to 13.0 cm. A. japonicum fed majorly on Euphausia pacifica (Euphausiacea, % index of relative importance; IRI, 51.9). However with growth, its diet shifted from copepoda to euphausiacea. Overall, as the body size of A. japonicum increased, the mean weight of prey within the stomach (mW/ST) increased.

This study was undertaken to assess eating habits and food consumption pattern of 365 adolescent girls in Kwangju area. Subjects were divided into 3 groups based on relative body weight as obesity index. Anthropometric data showed that mean height and weight were $161.9{\pm}19.0cm$ and $53.3{\pm}7.2kg$ respectively which are similar to those in the Korean Standard Growth data. Mean BMI and relative body weight were 20.50 and 97.1%. Age of menarche in the subjects significantly influenced the obesity index. Food habit score in the underweight group was significantly lower than that in the normal group at ${\alpha}=0.2$ level by multiple range test. Obesity was significantly associated with more frequent and irregular eating. It seems that students in the obese group were concerned on their body weight and tended to consume much vegetable. Obese group consumed more fruits, less butter and fruit juice compared to other groups. It might be suggested that more effective nutrition program might be developed and implemented to ensure good food habit of adolescent girls including obese as well as underweight group.

We investigated the feeding habits of Rhynchocypris kumgangensis in Hongcheon River of Saenggokri, Seoseokmyeon, Hongcheongun, Gangwon-do, Korea from April 2002 to March 2003. The fish is korean endemic species upper streams in Korea. It was asscertained that R. kumgangensis is a carnivore and consumes mainly Ephemeroptera, Diptera, Terrestrial insects and Trichoptera. The most important prey was chironomids: Chironomus sp. Their feeding habits changed according to growth. Small fish fed mainly on small prey organisms such as Diptera, while larger fish fed much more on Ephemeroptera and Terrestrial insects. There were also seasonal changes in the relative proportion of their food items.

Obesity during childhood is a dominant risk factor for noncommunicable diseases (NCDs), and is itself considered a disease that needs to be treated. Recently, the growth in childhood obesity in Korea has become stagnant; however, two in every ten children are still overweight. In addition, 60% or more of overweight children have at least one metabolic syndrome risk factor. Thus, childhood obesity should be controlled through lifestyle modification. This paper reviews studies of the modifiable risk factors of obesity in Korean children. According to the life-course approach, preschool-aged children (<5 years) are influenced by their parents rather than individual habits because they are under mostly parental care. Elementary school-aged children (6 to 11 years) are affected by overlapping individual and parental effects. This may mean that the establishment of individual behavior patterns begins during this period. The conditions of poor eating habits such as skipping meals, eating out, and high fat intake, along with low physical activity, facilitate increased obesity among adolescents (12 to 18 years). Notably, adolescent girls show high rates of both underweight and obesity, which may lead to the development of NCDs in their offspring. Therefore, the problem of NCDs is no longer limited to adults, but is also prevalent among children. In addition, early intervention offers cost-effective opportunities for preventing NCDs. Thus, children need primary consideration, adequate monitoring, diagnosis, and treatment to reduce the burden of NCDs later in adulthood.

The purpose of this study was to investigate the effects of swiss ball exercise and taping therapy on back muscle strength on normal college students. The aim of this study was to find effective method for back muscle strengthening. Subjects of 30 college students divided 3 groups(taping therapy group: 10, swiss ball group: 10, control group: 10). All subjects inquired physical conditions and normal exercise habits for data base. Back muscle strength measured before and after 3 weeks intervention. Taping therapy was displayed stable a growth curve in continuative a growth graph of back muscle strength better than swiss ball exercise, because it was taping therapy by periodic effect. The result of this study known to effective either taping therapy or swiss ball exercise, but both taping therapy and swiss ball exercise were effect to increase in back muscle strength.

Anthracnose fungi associated with soybean (Glycine max), small red bean (Vigna angularis), and green bean (Phaseolus radiatus var. aurea) were compared with respect to cultural characteristics, morphological aspects, and pathogenicity. From the legumes, four different species of Colletotrichum were identified based on their morphological characters : C. truncatum, C. destructivum, C. trifolii and C. gloeosporioides. Colonies of Colletotrichum spp.on culture media varied in colour and growth habits depending upon the media and isolates. In general, formation of conidia, setae, and perithecia on water agar leaf medium was better than that on potato dextrose agar medium under near ultraviolet light. In cross inoculation tests, isolates of C. truncatum, c. destructivum, C. trifolii and C. gloeosporioides could infect soybean, small red bean, and green bean at different growth stages. There were some differences in pathogenicity or susceptibility depending on crops tested. C. truncatum was the most virulent and major pathogenic species among the four species.
