We present the first demonstration of the environmental application of a polyimide film (Kapton) with patterned thru-holes as a novel, efficient, flexible, recyclable, and active particulate matter (PM) air filter. The Kapton air filter captures PM using micro-sized thru-holes and the strong electrostatic force because of its high work function. It is highly efficient, transparent, flexible, and heat-resistant. Furthermore, it can be recycled simply by washing it with tap water. The proposed PM filter is a promising candidate for use as a highly efficient and economical recyclable air filter for home appliances, such as air-purifiers, air-conditioners, and humidifiers, as well as industrial filtration systems.

BACKGROUND/OBJECTIVES:As the prevalence of chronic diseases has risen, the need for straightforward diagnostic tools for monitoring nutrition status to improve nutrition counseling and disease prevention has likewise increased.This study developed an easily usable dietary behavior pattern diagnosis checklist and investigated its correlation with dietary quality index.SUBJECTS/METHODS: A draft dietary pattern evaluation tool was generated by analyzing previous studies.The draft questionnaire comprised 61 questions for assessing dietary habits.A survey was administered to 320 adults (19 to 64 years old) using the dietary pattern evaluation tool and 24-hour-recall method between March and May of 2014 in Jeonbuk province and the metropolitan area.Principal component analysis with varimax rotation was performed to identify dietary behavior patterns.Nutritional analysis was conducted using CAN-Pro 4.0, and the Diet Quality Index-International (DQI-I) was calculated to assess dietary quality.The correlation between dietary pattern scores and DQI-I scores was also analyzed. RESULTS:The factor analysis resulted in a total of 34 questions mapped to four main dietary behavior patterns: "high fat and calorie" pattern (12 questions), "overeating/binge" pattern (nine questions), "dietary impulse" pattern (eight questions), and "unbalanced food intake" pattern (five questions).The four dietary behavior patterns were negatively correlated with DQI-I adequacy and total scores (P < 0.01). CONCLUSIONS:The dietary pattern evaluation tool developed in this study can be used to diagnose a client's dietary behavior problems and is available as a nutrition counseling tool in the field.

This study was conducted to develop expanding strategies of nutrition counseling in school foodservices. The study participants were 102 school dietitians in Gyeonggi province, and information on the current status, dietitians' necessity awareness, and practical activation needs for nutrition counseling were investigated. While 78.8% of dietitians were aware that nutrition counseling was in need, it was only 31.3% who understood the necessity of nutrition counseling. The implementation rate of students' nutrition counseling was 26.2%, and 74.0% of counseling dietitians reported that they conducted nutrition counseling because it was on the inspection list by the Office of Education. Overall, dietitians did not have high consciousness of the need for nutrition counseling. The implementation rate of students' nutrition counseling was remarkably low due to the reason of excessive work and insufficient participants, and it was interpreted that dietitians had a low intrinsic motivation for nutrition counseling. So, we suggested several strategies to activate school nutrition counseling as follows. First of all, dietitians needed to increase the students' participation rate by promoting the importance of nutrition counseling to students and by assigning their available work hours for nutrition counseling. Second, in academic communities, standardized counseling manuals and media covering the important nutrition and health issues should be developed and disseminated, and education programs needed to build up dietitians' self-esteem and knowledge on nutrition counseling. Lastly, the Office of Education should have the initiative in activating nutrition counseling in school foodservices by supporting a budget and counseling dietitians who exclusively responsible part-time counseling at schools.

The change in people's dietary life has led to an increase in an intake of processed foods and food chemicals, raising awareness about taste education for preschoolers whose dietary habits start to grow. This study aims to evaluate the effectiveness and satisfaction of parents and childcare personnel after developing a taste education program and demonstrating it in class. A part of the curriculum developed by Piusais and Pierre was referred for the program. After educating 524 preschoolers in child care facilities in Seoul, a satisfaction survey was conducted on the program. The data in this study were analyzed using SPSS 14.0. Statistical analysis was conducted based on the frequency after collecting the data. Mean ± SD used to determine satisfaction with taste education, with preferences marked on a five-point scale and the alpha was set at 0.05. The program includes five teachers' guides with subjects of sweetness, saltiness, sourness, bitterness and harmony of flavor, and ten kinds of teaching tools. For the change in parents' recognition of the need for taste education based on five-point scale, the average of 4.06 ± 0.62 before the program has significantly increased to 4.32 ± 0.52 (P < 0.01). Regarding the change in the preferences for sweetness, saltiness, sourness, and bitterness, the average has increased to 3.83 ± 0.61, 3.62 ± 0.66, 3.64 ± 0.66, and 3.56 ± 0.75 respectively. In an evaluation of instructors in child care facilities, the average scores for education method, education effect, education contents and nutritionists, and teaching tools were at 4.15 ± 0.63, 3.91 ± 0.50, 4.18 ± 0.50, and 3.80 ± 0.56 respectively. In addition, the need for a continuous taste education scored 4.42 ± 0.67. This program has created a positive change in preschoolers' dietary life, therefore the continuation and propagation of the taste education program should be considered.

Few studies have shown the correlation between metabolic syndrome and bone mineral density (BMD). The main pathogenic mechanisms of metabolic syndrome rely on chronic low-level inflammatory status and oxidative stress. There are few studies that examine the gender-specific effects of inflammation and antioxidants on BMD. In this study, we evaluated the relative contribution of these factors in patients with metabolic syndrome. We conducted a cross-sectional study of 67 men and 46 postmenopausal women with metabolic syndrome; metabolic syndrome was defined as having three or more metabolic syndrome risk factors. BMD, body fat mass, and lean body mass were evaluated. We also examined the levels of high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), adiponectin, vitamin E, and C in serum. Log-transformed hs-CRP levels were significantly higher in lumbar spine osteoporotic subjects than in normal subjects for women but not for men. There was no significant difference between the normal group and the osteoporotic group in other inflammatory markers. Stepwise regression analyses for BMD of the lumbar spine showed that lean body mass and vitamin E were significant determinants in men. Lean body mass and log-transformed hs-CRP were significant determinants in women Analysis for BMD of the femoral neck showed that lean body mass was a significant determinant for both men and women. There was no significant factor among the inflammatory markers or antioxidant vitamins affecting the femoral neck BMD for either gender. In conclusion, while hs-CRP is an independent predictor of the BMD of the lumbar spine in women, vitamin E showed profound effects on BMD in men but not women with metabolic syndrome.

A food exchange system for diabetes is a useful tool for meal planning and nutritional education. The first edition of the Korean food exchange lists was developed in 1988 and the second edition was revised in 1995. With recent changes in the food marketplace and eating patterns of Koreans, the third edition of food exchange lists was revised in 2010 by the Korean Diabetes Association, the Korean Nutrition Society, the Korean Society of Community Nutrition, the Korean Dietetic Association and the Korean Association of Diabetes Dietetic Educators through a joint research effort. The third edition is based on nutritional recommendations for people with diabetes and focuses on adding foods to implement personalized nutrition therapy considering individual preferences in diverse dietary environment. Foods were selected based on scientific evidence including the 2007 Korea National Health and Nutrition Examination Survey data analysis and survey responses from 53 diabetes dietetic educators. While a few foods were deleted, a number of foods were added, with 313 food items in food group lists and 339 food items in the appendix. Consistent with previous editions, the third edition of the food exchange lists included six food categories (grains, meat, vegetables, fats and oils, milk, and fruits). The milk group was subdivided into whole milk group and low fat milk. The standard nutrient content in one exchange from each food group was almost the same as the previous edition. Korea Food & Drug Administration’s FANTASY (Food And Nutrient daTA SYstem) database was used to obtain nutrient values for each individual food and to determine the serving size most appropriate for matching reference nutrients values by each food group. The revised food exchange lists were subjected to a public hearing by experts. The third edition of the food exchange lists will be a helpful tool for educating people with diabetes to select the kinds and amounts of foods for glycemic control, which will eventually lead to preventing complications while maintaining the pleasure of eating.

This study was conducted to develop a novel tomato sauce using natural seasoning. The data was analyzed using SPSS for Windows (version 14.0). Two factors of the tomato sauce were varied was tomato paste and sugar. Nine tomato sauces were produced with various compounding ratios of tomato pa ste and sugar. The color, viscosity and sensory evaluations of the nine tomato sauces were determined. Items examined in the sensory evaluation were color, sweetness, viscosity and overall quality. Sweetness(4.44±1.36), viscosity(5.16±1.28) and overall quality(4.68±1.11) of the tomato paste 340 g and sugar 100 g sample got highest scores. Therefore, this composition was used as tomato spaghetti sauce. Tomato spaghetti sauce using a natural tomato sauce and artificial to mato sauce was prepared and su bjected to a sensory evalua-tion. Items included in the sensory evaluation were taste, flavor, harmony, overall quality. In this analysis, all sensory item scores of the tomato spaghetti sauce using natural seasoning were significantly higher than when artificial season-ing was used. Therefore, the potential of commercialization of tomato sauces using natural seasoning was confirmed.

ABSTRACT The purpose of this pilot study was to examine the feasibility of using digital pictures to assess in-dividuals’ nutrient intakes from school lunch. The subjects for the study were 29 male students and 40 fe-male students from two classes in a middle school located in Daejeon Metropolitan City, Korea. The schoollunch service was self-operated and the students were allowed to portion the foods by themselves. The teach-er in charge of each class took digital pictures of every student’s lunch plate that was tagged with an i.d.number, before and after eating for two consecutive days. The researchers estimated the amount of food,which an individual actually consumed by comparing pre- and post-pictures of their plate with reference foodpictures for better visual estimation of the food amounts. Individual energy and nutrient intakes were calcu-lated using CAN-Pro (ver 3.0) using the food intake data visually estimated from the digital pictures andschool lunch recipes. The teachers in charge reported that about 10∼15 additional minutes were needed totake the pictures used for the study and this additional time did not place much burden on the service proc-ess during the lunch period. The results showed that the students’ actual energy and nutrient intakes from thesame school lunch menus were quite varied as the serving portions were not regulated and left-overs werenot prohibited. This pilot study suggests that examination of individual nutrient intake using digital picture isa feasible method in the context of school lunch service.Keywords: feasibility, digital pictures, school lunch, food intake

To identify the eating behaviour of customers at a hotel buffet styled restaurant, a survey was conducted. The age range of the respondents was 6 through 70, but consisted mainly people in their twenties, thirties, and forties of the respondents, 65.1% were female. The occupation ranged from student 30.3%, housewife 27.2%, office worker 19.3%, professional 17.3%. 43.9% of respondents visited buffet styled restaurant 1 to 2 times every three or four months. Some respondents had a positive opinions: they had many choices in food selection, they could take and choose as much as they wanted, the appearance and the arrangement of the food was great, etc. But some also had negative attitudes(i.e. unhappy with self service and expensive prices). Of the respondents, 31.1% said they visited the buffet styled restaurant was for family parties and the average number of the party member was . The average time period of eating was 1 hour minutes. The average frequency of taking food was . The average frequency of taking food after satiety was . The first selection of the buffet service food was soup 23.9% of the respondents and salad 23.9%. Females chose more of the soups and salads the males chose more of the meats and seafoods. The standard of food selection was 70.7% of 'my favorite'. This tells customers' low cognition level of desirable food selection and the order of a meal. 64.0% of the respondents responded overeating, from mild and extreme. We think that information on nutrition education and health problems are necessary. For better service, 82.9% wanted to lower the price by decreasing similar items. Respondent wanted; one, to increase more Korean food items and make a traditional Korean buffet styled restaurant, two, to use more seasonal food and decrease the redundant food items to reduce the price, and three, to have different price rates according to the age or gender of the grown ups.

This study was conducted to investigate the intake of a kind of Gom-Tang (Beef soup made with internal organs and bone), which is the Korean traditional food, and factors affecting the eating behavior of customers. Two hundred male customers of a H Korean Restaurant specialized in Gom-Tang, which is a well-known restaurant in Seoul, were surveyed from June 26 to 29, 1990. The results were shown as follows. (1) Frequency of intake and preference were very high. Those who took a kind of Gom-Tang more than once a week were 66.5% of the subjects. Those who evaluated good for the taste and flavor were 86.5% and 59.0% of the subjects, respectively. (2) The reasons why they chose a kind of Gom-Tang from among many Korean traditional foods were preference and phygiological condition in high frequency of intake group. Phygiological condition was more critical factor than preference in low frequency of intake group. (3) The effect of the intake of a kind of Gom-Tang on health was evaluated as healthy (80.5%). No effect and harmful were 30.5% and 6.5%, respectively. (4) High frequency of intake group, mainly more than 50 years of age, had a high preference and food knowledge as well as positive eating behavior and healthy state, Middle frequency of intake group, mainly the forties, had a high preference, but had less positive eating behavior than high frequency of intake group. Low frequency of intake group, mainly the twenties and thirties, had a medial preference. They took a kind of Gom-Tang for reasons of on the recommendation of friends better than preference. Foregoing results showed that a kind of Gom-Tang was a typical food recognized as healthy as well as delicious. This may suggest that a kind of Gom-Tang is a candidate for the effective food on nutritional education.

An eating behavior research was done with 50 females at a buffet styled restaurant during their lunch time. Of the respondents, 52.0% were professional and 54.0% were graduate school graduates. Of the respondents, 58.0% of the company were friends and 24.0% were relatives. The average time period of eating was minutes. The average frequency of taking food was and the average frequency of taking food after satiety was . It is significant that lower frequency of food consumption was directly proportional to the age groups of respondents. The average selected food items were out of 175 and the average weight of the consumed food was g. The older age group chose a similar number of food items, but the amount of each food item was considerably less than younger. So the younger the age group was, the more they ate. The average food items at one time was and the average food weight time was g. The percentage of respondents who evaluated themselves as 'ate too much' was 70.0% and those who evaluate themselves 'ate properly' was 14.0%. Most of them were satisfied with the buffet service. The average of number of food items consumed by respondents before cooking was . The consumption of calories and nutrients was compared with the Korean Daily Recommended Dietary Allowances. The consumed calories were 60.9% of RDAs, protein 104.4%, calcium 77.1%, iron 129.8%, vitamin A 66.5%, thiamin 96.0%, riboflavin 95.7%, niacin126.6% and ascorbic acid 112.3%. This data exceeded 1/3 of the Korean Daily RDAs tremendously and tells us extreme overeating. The energy ratio of carbohydrate: fat: protein was 51.6: 29.9: 18.5. Caloric consumption of animal food was 27.9% and the consumption rate of the other nutrients from animal food was considerably high. But the consumption rate of vitamin A was 90.9% from vegetable groups. Accoding to this study, buffet service gives some advantages. It gives customers an good opportunity to vary their food intake, which enhances eating experiences and can cause an improvemont of food habits. But overeating is a problem. Therefore, we think it is necessary for those women who have influence over their family's food selection, to have nutrition education about a desirable order of eating a meal, food selection, and health problems due to overeating at buffet styled restaurant. There should be some improvement in the management of buffet service. For example, proper temperature, texture, and freshness of the food should be maintained. Prevention of mixed food smells should be considered as well. To lower the price it is desirable to reduce the number of similar items and to use seasonal food as much as possible. A buffet styled restaurant with less food items with cheaper prices is recommended. Various traditional food should be developed for the menu items. We expect buffet services to be sutable to maintain good health and to be popular to any eater.

In accordance with the rapidly growing number of street food service without a registration, a study was undertaken to determine the present state of food service by the covered wagon bar, through an investigation in Jamwondong, around the south gate market and Kangnam subway station, in Seoul, between July 25th and August 25th of 1987. The survey was comprised of three parts: 1) foodservice operation in covered wagon, 2) personal and food handling hygiene, 3) food behaviors of customers. A total of 54 covered wagon bars, consisting of 51.8% mobile bars and 48.2% non-mobile bars, operating in the above three locations, were investigated. Survey results show non-mobile covered wagon bars to be more popular among persons in their thrities and fourties than among teens or the elderly; also among males than females; among company employees and college students than others. Seventy five percent of the mobile covered wagon bars served snack type foods and others served wine and foods for wine, in contrast to hundred percent of the non-mobile covered wagon bars served wine and foods for wine. The survey found many problems of hygiene, in method of food purchasing, menu planning, food preparation, dish washing treatment of leftovers and water supply, as well as personal hygiene. However, customers prefer the casual and popular atmosphere at the counter of the covered wagon bar. Finally, the study emphasizes a need for better operation of covered wagon bar, improvement of food stuff handling and the way of food services and personal hygiene. A change of the registration system from the illegal operation are urgently needed for better quality food services of covered wagon bars.

To determine dining out behaviours of fast foods at five different fast food restaurants of Youido apartment compound in Seoul, a survey was conducted of 460 customers ranging in age from 7 to 29 year, from October 1 to 5th, 1986. Findings are summarized follows: The reasons the customers the fast food restaurants by the highest percentage were the following in the order: 'the atmosphere in which fast food is eaten is enjoyable for the companionship', 'convenient to dining', 'the surroundings and dining equipment are pleasant and hygienic', and 'to be able to stay as long as I want'. The majority of the customers visited the fast food restaurants with their friends between 1pm and 5pm. The fast foods purchased by the customers were mostly for snack rather than a full meal. Preference was a major factor in food selection from available meun items. Ice cream, Kentucky fried chicken, rolled rice with laver I rice cake stew, fried Mandoo were ranged high on the list of liked foods, in contrast, lower preference was for noodle soup, small red bean porridge, pinenut porridge, and persimmon punch.
