The purposes of this study were to : (a) analyze the portion size & plate waste of normal & soft diets provided by dietetic departments in hospital, (b) investigate the factors affecting plate waste, and (c) determine the nutritional & monetary value of plate waste. A questionnaire for food preference and sensory evaluation was developed and a survey was carried out for the 46 normal diet and 56 soft diet patients in Sanggye Paik hospital in Seoul. Serving size and plate waste were weighed by the electric scale, and CAN-Pro program was used to evaluate the nutrition value. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and Pearson correlation. The average plate waste rate for normal diet and soft diet were 30.3% and 49.6%. More plate waste amount occurred on female patients'diet than male patients'diets regardless of the kind of diet. The plate waste percentage of male patients were higher than those of female on normal diet. On soft diet, patients who hospitalized in surgery or pediatrics department were higher than in other wards. Plate waste of normal diet and amount were correlated positively, but wastage and preference were correlated negatively Negative correlation was between taste and plate waste, and between temperature and plate waste, too. On the other hand, plate waste caused the deficiency of some nutrients such as Ca, Fe, Vit. B$_2$and a great monetary loss.

A nutrition education program has been designed for the children of obese or unbalanced dietary habits. A total of 120 children(60-obese and 60-unbalanced dietary habits) who were in 5th-6th grade was chosen for the program and the effectiveness of the nutrition education was evaluated. The nutrition education program was organized into daily lessons(3 wks). A booklet was made for the education and used during the education period, dealing with 5-Basic Food Groups and their functions, excess or deficiency in a human body, food exchange list, importance of health, obesity, unbalance dietary habits and of school lunch program were emphasized in every day session. dietary recall records were collected to assess their daily food intake and the amounts of meals were discussed. During the education period, booklets, wall charts, photographs, food models, VTR films and slide films were utilized. Assessment of effects of the nutrition education program was carried out by a nutrition knowledge test, food habit records, anthropometric measurements and food preference test. The nutrition knowledge scores were significantly improved after the education and the scores were higher on the children in the school with school lunch program. The anthropometric measurements and food preference test revealed no significant influences of the education on the children, showing that the education period was too short to change their eating behavior any may need a long-term education program. Food habit scores were improved after the education in both experimental and control groups. The experimental groups showed higher scores than the control group.

A nutrition education program for teachers and caregivers of the preschool children can be most effective when it is based on a comprehensive needs assessment dealing with sociodemographic factors, dietary habits, and nutrition. The purpose of the present study was to investigate current dietary habits and nutrition knowledge of the teachers and caregivers of the day-care centers. Two hundred forty two teachers and caregivers were administered a questionnaire which was designed to ascertain informations on sociodemographic data, dietary habits and nutrition knowledge. Dietary habits of the teachers were found to be significantly different by sociodemographic variables; breakfast skipping/meal irregularities (age, p=0.011); frequency of snacking (education level p=0.031); preference for salty taste(age, p = 0.000, marital status p=0.038); preference for sweet tarte (age p=0.009); preference for vegetables (income level p=0.050); frequency of eating out (age p=0.028, marital status p=0.001); frequency of coffee drinking (age p=0.019). Daycare center teachers' nutrition knowledge level was found to be less than adequate expecially on nutrients that are liable to be deficient in young growing children and their food sources. Proportions of the teachers who answered correctly to the questions on foods rich in vitamin A, iron content of milk, bioavailability of calcium in plant foods were as low as 20.2%-54.5%. The most frequently used sources of nutrition information were mass media such as TV, radio, newspaper and magazines. Only 2.9% of the subjects reported that they obtain nutrition information from health professionals such as nutritionists/dietitians, physicians, and nurses. These findings are applicable at the planning and implementation stages of various nutrition programs for the improvement of dietary habits and nutrition knowledge of the teachers and caregivers of the daycare centers. Further studies are needed to investigate the effects of teachers' dietary of habits and nutrition knowledge on food habits of young growing children.

In this study, the distribution, bait preference, hosts, symbionts, habitat status, and cytochrome c oxidase subunit-I sequences of the ant Linepithema humile were analyzed. This species habitat comprised approximately 1.5 km along stone crevices, flower gardens, roadsides, and container yards in the vicinity of Busan station, Korea. Feeding activity of this species was confirmed in 9 species of 7 families of plants. Which was approximately 14% of total flora (63 species of 37 families) in the studied area. Particularly, it was observed that Dendranthema indicum and Camellia japonica were the most frequently visited. Further, we verified that they interacted with four species of aphids. We identified 22 species of ants (17 genera, 4 subfamilies) inhabiting the Busan station area, including L. humile, Tetramorium tsushimae, Nylanderia flavipes and the alien species Paratrechina longicornis. In areas where L. humile was the dominant species, the habitat of local native ants was reduced by approximately 30%. Bait preference was ranked in the following order: jelly, water with glucose (25%), and yogurt, with the highest preference for baits containing sugar and protein. The 630-bp cytochrome c oxidase subunit-I sequences of the local L. humile populations were 99% identical to those of L. humile in the National Center for Biotechnology Information database, and the Argentine ants that invaded Korea had a sequence identical to that of other invasive populations from China, Japan, and New Zealand. As L. humile rapidly increases due to domestic adaptation, continuous monitoring and control strategy for eradication are needed to protect domestic biodiversity.

The Attention Restoration Theory (ART) developed by Kaplan and Kaplan proposes that effortful directed attention required in normal life can be fatigued. Restoration can occur in a setting that has restorative qualities. The restorative quality described by the ART involves four concepts: being away, fascination extent, and compatibility. The purpose of this study was to investigate how the restorative quality of landscape influenced the preferences and satisfaction of visitors to an heritage landscape. Four kinds of heritage landscapes of Kyongju were used as environmental surrogates and 150 americans participated in the study. Hartig et al.'s Revised Perceived Restorativeness Scale (RPRS) was used as the psychological measure for the restorative quality, along with other measurement constructs such as cultural uniqueness and novelty. The results showed that RPRS was a reliable measurement tool for assessing the restorative quality of artificial landscapes. Factor analysis identified three valid factors: escape-fascination compatibility, anti-extent. Among the three factors, only two, escape-fascination and compatibility, were found to have important effects on visiting preference and satisfaction. Specifically, higher levels of preference and satisfaction were associated with higher levels of escape-fascination and compatibility. The results indicate that the restorative quality has a high possibility to be used as a frame of reference for assessing various types of landscapes, from natural to artificial. It was also proposed that restorative quality could better explain the experience of the landscape strongly related to specific purpose or motivation.

This study was to develop and evaluate a nutrition education program to reduce dietary sodium. The school children (218 boys, 226 girls), from 8 elementary schools in the city of Daegu, Korea, were involved in this study. This research was based on the data from two groups of elementary school children, the "education" group (n = 240), and "no-education" group (n = 204). Educational media and programs were developed to educate the education group for four weeks and were presented on the web (www.saltdown.com). After education, the preference for a non-salty taste in the education group increased 10%, compared with those who preferred a non-salty taste before education. There was a significant change away from a preference for a salty taste and a rise in the mean score for nutrition knowledge and dietary attitude in the education group compared to the no-education group (p < 0.05). This study indicates that school children can reduce their dependency on preference for a salty taste and change their high-salt dietary behavior after the education.
