Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.
A large amount of food waste in known to bring about many problems including environmental pollution. This study was carried out to investigate effective methods for reducing leftovers in the food service business & industry. The reasons for producing leftovers in food service restaurants, customers perferences of foods, cooking methods the degree of saltiness, and serving size were surveyed using questionnaire and the menu was improved based on the customers perferences. Excessively large serving sizes and the unfavorable cooking methods is food service were the main reason for the leftovers of side dish and one=dish foods. Because the largest amount of leftover came from soups & stews, an effective way of reducing leftovers in food service would be to reduce the serving size of soups & stews. Total leftovers was reduced to about 60% after improving menu (p<0.01) and the each leftover or rice, soup&stew, and side dishes was also reduced significantly after improving the menu(p<0.001) The environmental campaign to reduced food waste by bulletin intra-net using personal computers slogans& posters, and new letters was conducted for one week each and then leftovers were measured 9 times for following three weeks regularly. The total amount of leftovers decreased slightly due to the environmental campaign, but the difference was not significant . When we adopted penalty or prize system leftovers were decreased by about 35%(p<0.001) and the penalty system was more effective than the prize system in reducing leftover (p<0.001) When we compared the leftovers under the three services, a tray service was more effective in reducing leftover than complete self-service of partial self-service(p<0.001).

The objective of this study was to investigate the growth rate and the optimal stocking density of sea cucumbers. Grow-out was studied in situ by conducting a follow-up survey using visible implant elastomer (VIE) tags. The rearing systems were made of polypropylene pipe for the frames and netting. The experiment ran for 70 days near Yeosu, Korea in the water depth of about 7 m. A total of 576 sea cucumbers which have three groups of body sizes (small: 5.15, medium: 12.34 and large: 23.26 g) were used. The five groups of stocking densities (150, 300, 450, 600 and $850g/m^2$) in rearing system for sea cucumber were considered. Sea cucumbers were fed a mixed diet (mud, mineral, fish meal, etc.). The feed was supplied to 10% of their body wet weight once every 7 days. The survival rate (73%) of sea cucumber in $850g/m^2$ was lower than those of other density groups ($150g/m^2$: 89%, $300g/m^2$: 84%, $450g/m^2$: 78% and $600g/m^2$: 86%). The survival rate of medium size group was higher than those of small and large groups regardless of the density (P<0.05). Most of density groups have no significant difference except for $850g/m^2$ (P>0.05). The growth rate of small size group ($0.63%day^{-1}$) was higher than those of medium ($0.38%day^{-1}$) and large ($0.34%day^{-1}$) group regardless of the density (P<0.05). The threshold water temperature was $11.0^{\circ}C$ for sea cucumber growth in winter season.

Soybean Kunitz trypsin inhibitor(SKTI) protein is a small, monomeric and non-glycosylated protein containing 181 amino acid residues and is responsible for the inferior nutritional quality of unheated or incompletely heated soybean meal. The objective of this research is to confirm SSR marker(Satt228) tightly linked to the Ti locus using several germplasm accessions with TiTi or titi genotypes for MAS in soybean breeding programs. TiTi genotypes('Jinpumkong2', 'Clark', and 'William') had allele1 and titi genotypes(PI196168, C242, W60, and PI157440) had allele2 in Satt228 marker analysis. 'Jinpumkong2', 'Clark', and 'William'(TiTi genotype) had a Kunitz trypsin inhibitor protein of 21.5 kDa size, and PI196168, C242, W60, and PI157440(titi genotype) did not have the band in protein gel electrophoresis from the mature seed. Cosegregation between the SKTI protein(21.5 kDa size) and allele of Satt228 marker was observed in seven germplasm accessions with different genetic backgrounds. Any recombination between the SKTI protein and allele of the Satt228 marker was not observed. This result indicates that Satt228 marker may effectively utilized to select the plants with the titi genotype.
The purpose of this study is to analyze external elements of 'time series table serving' and to discover any problems in the table setting. We selected two traditional Korean restaurants in five-star hotels and two representative traditional Korean style restaurants and analyzed the tableware arrangement of their table settings. The results are as follows. In restaurant A, the arrangement of different styles of tableware made from a variety of materials seemed relatively natural. However, the dessert plates were 'Buncheong' ware made with 'Bakji' method; in this case, the pattern was larger than the size of the fruits served and made the food inconspicuous. Rather than using plates made with a 'bakji' method, using plates with small patterns in the 'johwa' method would complement the food. In restaurant B, the space between the tableware, spoon and chopsticks was narrow, and the spoon and chopsticks sets would not fit on the table pads when large dishes or multiple dishes were served. In this case, changing the dishes to smaller sized dishes, considering the size of the table pad, or not using the pad at all would solve the issue. In restaurant C, too many small dishes were laid on the table, making it look disorderly. We believe that recovering tableware that is no longer in use, laying dishes and cutlery inside of the table pads or not using the table pad would be better. In restaurant D, the same style and color of dishes were provided 9 times. The lack of variety could be tedious to customers. The forms and colors of dishes should be changed in accordance with the order of the meal served. However, when using tableware created by different methods such as 'Buncheong' ware or white porcelain, the same pattern should be chosen in order to elevate the dignity of the table menu through uniformity. These issues in tableware arrangement indicate that external forms of banquet table setup should be studied so that the culture of Korean traditional cuisine can be enriched.

This research is concerned with the fungicidal properties of nano-size silver colloidal solution used as an agent for antifungal treatment of various plant pathogens. We used WA-CV-WA13B, WA-AT-WB13R, and WA-PR-WB13R silver nanoparticles (AgNPs) at concentrations of 10, 25, 50, and 100 ppm. Eighteen different plant pathogenic fungi were treated with these AgNPs on potato dextrose agar (PDA), malt extract agar, and corn meal agar plates. We calculated fungal inhibition in order to evaluate the antifungal efficacy of silver nanoparticles against pathogens. The results indicated that AgNPs possess antifungal properties against these plant pathogens at various levels. Treatment with WA-CV-WB13R AgNPs resulted in maximum inhibition of most fungi. Results also showed that the most significant inhibition of plant pathogenic fungi was observed on PDA and 100 ppm of AgNPs.
In disease surveys from 1986 ti 1998, disease incidence of tobacco black shank was gradually increased in burley tobacco from 1996. To study the causes of the disease occurrence, one hundred and fourteen isolates of Phytophthora parasitica var. nicotianae (Ppn) were collected from burley tobacco-growing areas in the southern part of Korea during 1996-1997, and tested in vitro for meatlaxyl sensitivity which was determined by measuring the mycelial growth on corn meal agar (CMA) amended with metalaxyl. Of the tested isolates, 78.1% showed sensitive to metalaxyl, having $\textrm{ED}_{50}$ values less than 1.0 $\mu\textrm{g}/$\textrm{ml}, while 1.7% was resistant weth $\textrm{ED}_{50}$ greater than 100 $\mu\textrm{g}/$\textrm{ml}. Ppn isolates from three provinces, Chungnam, Chonbuk and Chonnam showed similar distributions of metalaxyl sensitivity. Metalaxyl-resistant isolates were not significantly different from metalaxyl-sensitive ones in mycelial growth rate, chlamydospore formation capacity and size of the spore, and pathogenicity on tobacco plant (cv. Burley 21). These results suggest that the metalaxyl-resistant Ppn in burley tobacco may be one of the major factors to cause the higher occurrence of the tobacco black shank in the burley tobacco-growing area.
Purpose: The purpose of this study was to investigate the prevalence fate of obesity and to assess the relationship between obese children and their family Characteristics in 3 rural area in the Chung Cheong Nam Do province. Method: The children's height, weight and family characteristics of 327 5th and 6th grade elementary school students were obtained from the individual health records and self-recorded questionnaire surveys from June 25th to July 15, 2004. Results: The results of this study are summarized as follows: 1. The prevalence rate of obesity of 5th and 6th grade of rural elementary school students was 10.5%. 2. 20.9% of obese children had obese family members and 9.4% of obese children did not have any obese family members. The birth order, family size and family structure showed no significantly difference. 3. The obese children were more affected by their parents' concerns of body image (upper quartile of 84.1) and exercise (upper quartile 61.4%) than normal children. However, there was no significantly increase with the parents' concerns about meals. 4. There was no relationship in the obese children by PBI. 5. There was no relationship in the obese children by FACES III. Conclusion: The elevation of a parent's concern of their obese child about meal regulation should be investigated further.
This study was conducted to assess the effect of nutrition counseling for postoperative female breast cancer patients (N = 38). In baseline survey, we investigated the nutrition parameters by measuring anthropometric and biochemical blood index and assessing nutrient intake using recall method. Individual nutrition counseling was performed 3 times with 2 - 3 weeks intervals. Patients were offered nutrition information related to breast cancer and desirable life style after cancer operation. The effects of counseling program were assessed 2 month later. Of biochemical parameters, serum total cholesterol level was significantly reduced after nutrition counseling program. Nutrient intakes of postoperative breast cancer patients were generally below the RDA level at the baseline survey. After nutrition counseling, mean daily intake of total energy, protein, calcium were significantly elevated. Of dietary habit, meal regularity and control of portion size were improved and fruits and vegetables intake were significantly increased after nutrition counseling. Control of fatty food intake and alcohol drinking were significantly improved after nutrition counseling program. Score of general nutrition knowledge and knowledge about breast cancer, were significantly increased after nutrition counseling from 2.1 to 3.2 and from 2.3 to 3.8, respectively. It can be postulated that the dietary habit and nutrients intake of postoperative breast cancer patients can be improved by individual nutrition counseling program. In further study, the systematic group nutrition counseling program is needed.
This study was conducted to assess nutritional status of the elderly from low-income urban area and to investigate environmental and health risk factors that may influence to nutrient intakes. One hindered eighty three(males 53, females 130) healthy homestaying subjects aged over 65 years in Seoul were assessed with anthropometric measurements and dietary intake in August, 1994. HT and BW for females were decreased with aging. The proportion of hypertension was 36% with indite of $SBP{\;}(SBP{\;}{\gg}{\;}160mmHg)$ and 52% with indice of DBP $(DBP{\;}\gg{\;}97mmHg)$. Distribution of BMI, OR and PIBW indicated that BMI was more sensitive for identifying underweight whereas PIBW was more sensitive for identifying overweight. for group aged over 75, males had significantly lower intake of energy, protein, fat, calcium, iron, vitamin A and $\beta$ carotene compared to the group aged 67~74, while females had lower intake of calcium and vitamin A. Elderly group with smoking, less familly size and living alone had lower nutrient intakes. Blood pressure in the elderly subjects did not influence to nutrient intakes, except elderly with normal blood pressure were taking increased amount of thiamin and niacin.
