The purpose of this study was to investigate convenience foods at convenience stores, by examining consumption patterns, as well as the degree of checking food-nutrition labeling. In this study, 208 workers in Busan in their 20s or 30s were surveyed using 1:1 interview questionnaires. The weekly usage frequencies of cup-ramyeon, gimbap, ramyeon, and sandwiches were 41.0%, 39.4%, 32.7%, and 19.0% respectively. The usage frequency of convenience foods was 12.0% for 'over 5 times/week', 23.0% for '3~4 times/week', 31.7% for '1~2 times/week', 29.8% for '1~2 times/month', and 3.4% for zero usage. Workers in their 20s showed a significantly (P<0.05) higher rate in the '3~4 times/week' as well as '1~2 times/week' intervals than workers in their 30s. Single people showed a significantly (P<0.01) higher rate than married people. Workers in their 20s showed a significantly higher score for the '3~4 times/week' as well as '1~2 times/week' intervals (P<0.05). The mean score of checking food labeling was 4.02/5.00 for the manufacturer's date, or expiration date, 3.23/5.00 for weight or volume, 2.99/5.00 for cooking method, and 2.85/5.00 for storage method. Females showed significantly (P<0.01) higher rates for checking the manufacturer's date or expiration date, as well as source of the raw material. Single workers showed significantly (P<0.01) higher rates for checking the manufacture's or expiration date as well as storage method. The mean score for checking nutrition labeling was 3.06/5.00 for calories, 2.84/5.00 for trans fat, 2.80/5.00 for sodium, and 2.76/5.00 for cholesterol. Females showed a significantly (P<0.01) higher rate for six of 10 items. Workers in their 20s showed a significantly (P<0.05) higher rate for four of 10 items. Expert officials showed significantly higher rate for six of 10 items (P<0.05) and two of 10 items (P<0.01), respectively.

The purposes of this study were to investigate the eating status and to analyze expenditures of the traditional fermented foods. A structured questionnaire survey was conducted from 370 housewives in Jeonbuk province and there were 300 usable samples(81.1%) valid for analysis. For the statistical analysis, the data was analyzed by $x^2$-test using SPSSIPC 12.0 for windows. The results of this study were as follows : 1. In the investigation on the eating status of the traditional fermented foods, Kimchi showed highest intake frequency(over once a day) and next Doenjang, Gochujang, Ganjang were consumed $2\;{\sim}\;3$ times per week. Jeotgal and Jangajji consumption showed the significant difference frequencies between the age groups(p < 0.001). The frequencies of using the home-made fermented foods were either similar or decreased, while the manufactured products were either similar or increased. The reasons behind the decreasing consumption were 'because of appetite change(47.0%)', 'the effect of western food(25.2%)' and 'dislike of salty food(17.4%)'. 90.7%(Kimchi), 54.9%(Doenjang), 54.8%(Gochujang), 53.2%(Cheongkukjang) of respondents knew the methods of preparation, while 62.5%(Ganjang), 41.1%(Jeotgal,) 31.2%(Jangajji) of respondents didn't know the methods of preparation. 2. In the analysis of the expenditure for the purchasing of the traditional fermented foods, most of the respondents procured Kimchi, Doenjang, Gochujang from their families or relatives, but they bought Ganjang, Jeotgal, Jangajji in the markets. And most of the respondents bought the fermented foods in the general merchandise stores or the department store except Kimchi. The places of buying Kimchi were specialty stores(34.6%), general merchandise stores or department stores(25.0%). Overall scores of satisfaction for the quality of manufactured fermented foods showed 3.29 of 5 - point scales. The average cost per month of Kimchi was 19,550won and Gochujang 7,878won, Doenjang 5,764won, Jeotgal 5,439won, Jangajji 5,412won, Ganjang(for soup) 4,714won, Cheongkukjang 4,677won, Ganjang(for seasoning) 4,464won, and total cost was 20,920won. The reasons behind purchasing the traditional fermented foods were 'because of convenience(58.4%)', 'no time to make by oneself(23.0%)' and 'for not knowing the making methods(12.8%)'. The problems of the manufactured traditional fermented foods were 'worry about safety of the raw materials or additives(71.2%)', 'lack of sanitation(12.0%)'. The most important thing considered in purchasing was 'materials and origins(86.6%)' and next 'quality(64.1%)' was another important thing.

To investigate the consumption pattern of traditional fermented soybean products a survey was con-ducted to the subjects composed of 308 housewives in busan yangsan and ulsan. Doenjang was rated among one of the often-used traditional foods in Korean meal preparation. 67.2% fo the respondents used Doenjang once or twice a week and 22.7% every day and by the educational level the lower in education level used more. Doenjang has been prepared by housewives themselves(46.9%) or by their relatives(30.7%) for the most important reason of good taste and by purchasing of commercial products(22.4%) for convenience. By regional groups the frequency to use commercial products of Doenjang was higher in Ulsan and the younger or the higher in education level showed the higher frequency. The consump-tion pattern of Gochujang was very similar to that of Doenjang. Chunggukjang which has peculiar flav-our showed very low consumption with being rarely used or having not eaten by 60.3% of subjects. Gan-jang was consumed mainly once or twice a week and jin-ganjang was preferred than Guk-ganjang. In the preparing methods Guk-ganjang have been made by housewives themselves(31.0%) by their relativ-es(29.5%) or by purchasing of commercial products(31.0%) and Jin-ganjang mainly by purchasing of commercial products(65.0%) which showed higher consumption frequency of commercial products com-pared with Doenjang and Gochujang.

We investigated the intake trends of street foods for middle school, high school and colleges students through the survey study. In addition, the factors affecting the students' consumption of street foods and their perception toward hygiene status of street vendor were studied. The levels of total aerobic bacteria, coliform groups and enterobacteriaceae in Kimbab, eomuk, and eomuk-kukmul were counted using 3M petrifilms. More than ninety seven % of the respondents had experienced street foods. All the respondents ate street foods 1 to 5 times a month. Forty percent of the respondent stated that 'good taste' and 'time-saving convenience' were their reason for eating the street foods. Their favorite foods were ddokbokgi and various fried foods. All the students responded that frying oil, drinking water, and soy sauce as well as the street vendors' attire and their cooking tools in street vendor were unsanitary. Forty percent of the respondents ranked frying oil as the most unsanitary substance. Eighty percent of the respondents responded that an enforcement of hygiene should be imposed on the street foods vendor. There were significant differences (p<0.001) among the student's age in the opinion related to the reasons of eating street foods, hygiene enforcement, existence of street foods and interest of hygiene status of street foods. High correlation (p<0.05) between the frequency of street foods and snack intakes was shown, regardless of student's age. The result shows that those who eat snacks more than once a day tend to eat street foods more frequently. Aerobic plate counts in Kimbab in 5 different vendors exceeded 10$^5$/g and contamination levels of enterobacteriaceae or coliform in Kimbab exceeded more than 10$^3$/g, which did not satisfy the microbiological standards. In conclusion, although the respondents thought that the sanitation of street foods was poor, most of them want the street food vendor to be maintained with better hygiene condition. This indicated that the regulation for safe street foods should be enforced and educational information about the preparation and serving for safe street foods should be provided to street food vendor.

Purpose: The purpose of the study was to compare dietary habits, perception, and consumption frequency of fast foods between part-time working youths at fast food restaurants and those at other food-related services. Methods: The study subjects were part-time working youths in 13 fast food restaurants (n = 118) and in 25 other places including bakeries, cafes, convenience stores, and other restaurants (n = 115) in Cheongju. Demographic characteristics, dietary habits, perception regarding fast foods, and consumption frequencies of food groups and fast foods were assessed using a self-administered questionnaire. Results: Female youths working at fast food restaurants had unhealthier dietary habits, such as meal skipping and night snacking compared to those working at other places. Consumption frequencies of fruits in males and beans/bean products in females working at fast food restaurants were significantly lower than those working at other places. Perception score on fast foods was significantly lower in males working at fast food restaurants than in males working at other places. However, the consumption frequencies of hamburgers, pizzas, and a total of six fast foods among both males and females working at fast food restaurants were significantly higher than those working at other places after adjusting for confounding variables including age, status, type of residence, allowance, alcohol, smoking, working hours, and hourly pay. Conclusion: Part-time working youths at fast food restaurants had worse dietary habits, such as meal skipping and night snacking, and consumed fast foods more frequently than those working at other places. Interventions for part-time working youths at fast food restaurants may be needed in order to reduce fast food consumption and increase the intake of fruits and vegetables.

The purpose of this study was to evaluate the important changes and the trends in Korean newspaper articles related to 1) food habits and food consumption patterns 2) nutrition, health and diseases 3) food safety and policy. The method used in this study was content analysis of the articles pressed in Donga ilbo and Choseun ilbo from January 1960 to June 1996. Among the total 1814 articles, those on nutrition, health and disease were 922 (50.8%), food safety and policy were 490 (27%) and food habits and consumption patterns were 402 (22.2%). The articles related to food habits and consumption patterns dealt with four contents, food habits reformation, changes in food consumption patterns, nutritional status and food habits. The frequencies of food habits content were highest (51.1%) and especially increased in 1980's and 1990's as the concerns on health and pursuit of convenience were increased. Most of contents related to food habits were health and longevity diet (44%) and eating out (27.5%). The percentile of food habits reformation, the changes in food consumption patterns and nutritional status were 20.1%, 18.4% and 10.0%, respectively. The contents of food habits reformation were most interested in 1960's when food shortage and poverty prevailed. Nowadays, the major subjects of food habits reformation were changed to the problem of wastage and the use of our agricultural foods. The frequencies of change in food consumption patterns were gradually increased from 1960's (7 item) to June 1996 (34 items). And the most of contents related to nutritional status were focused on suffering from food shortage especially in 1960's.

Purpose: This study was to evaluate the microbiological quality of salads in lunchbox's based on the holding time and temperature at convenience and franchise stores. Methods: Cabbage salad and crab meat salad were targeted for microbiological quality assessment. They were tested for aerobic plate counts, coliforms, Escherichia coli, Staphylococcus aureus and Enterobacteriaceae and assessment were performed by Korean Food Standards Codex. Results: In cabbage salad at convenience franchise store's at $5^{\circ}C$, the aerobic plate counts did not exceed the Korean Food Standards Codex. For cabbage salad stored at $25^{\circ}C$, the aerobic plate counts was 5.08 log CFU/g we hours after purchase, which exceeded the Korean Food Standards Codex. In case of cabbage salad in franchise store, the E. coli and S. aureus count exceeded Korean Food Standards Codex 3 hours after purchase. Microbiological analysis did not exceed the Korean Food Standards Codex at $5^{\circ}C$ in crab meat salad in convenience store. At $25^{\circ}C$, the aerobic plate count was detected at 4.45 log CFU/g after 32 hours, coliforms, E. coli, and S. aureus did not detect, but Enterobacteriaceae was found to be 2.34 log CFU/g after 9 hours in franchise store's crab salad. Coliforms was detected at 1.18 log CFU/g after 3 hours, and S. aureus was detected at 2.04 log CFU/g after 6 hours at $25^{\circ}C$ in the franchise store. The lunchbox' salad under cold storage ($5^{\circ}C$) generally meet the Korean Food Standards Codex. Conclusion: The results indicate an urgent need to implement proper management guidelines for the production of lunchbox foods to ensure microbiological safety, and to improve the shelf life from production to consumption.

Objectives: The purpose of this study was to compare Fast foods and Soft drinks consumption of Korean adolescents in a large city, a medium city, and a rural area. Methods: This was a descriptive comparative survey using a convenience sample of 2,261 8th and 11th grade students. The data were analyzed by X2-test and ANOVA using SPSS 10.0 statistical program. Results: For fast food consumptions, the higher in a large city than in a medium city and a rural area(p=.000). For soft drinks in a school, cafeteria or vending machines was higher in a large city and a medium city then in a rural area(p=.000). For eating snacks including cookies and popcorns was higher among students in a rural area than those in a medium city and large city(p=.008). Conclusions: 1. Overall, the health information among rural students is lower than those among other areas, as well as taking a health education course among rural students is also lower. Thus, the health inequality by regional differences should be considered. To decrease health inequality among different regions, health professionals who can systematically teach a health education course for middle and high school students and undertake students' health are needed. 2. Soft drinks sold in schools are higher in a large city and medium city than in a rural area. Therefore, there is a need of strong regulations and policies about the restriction of soft drinks sold in vending machines or school cafeterias.

With the recent rapid increase in single-person households, food companies are releasing small packaging and small-capacity products regardless of product line such as beverages, fresh foods, and home snacks, and food consumption patterns are also changing. Meanwhile, as a series of accidents related to food safety occurred during cost-effective consumption pursuing price-performance, more consumers wanted to choose products that have been proven safe even with higher money due to food safety anxiety. Considering the concept of 'safety' of food, this study by using the 'ordered probit model' empirically investigated whether there is a difference in the degree of preference for safety in food consumption behavior between single-person and multi-person households. Summarizing the results, it was found that women rather than men, and elderly households among young and single-person households had a higher demand for food safety. The results of marginal effects considering food safety variables show that respondents with low frequency of delivery and take-out use are considering food safety more, and that single-person households are considering safety more than multi-person households. In the future, the population structure of Korea will continue to increase in single-person and elderly households, and women's economic activities will also continue to increase. Therefore, the growing home convenience food market needs marketing strategies to secure and emphasize food safety, such as sterilizing treatment technology for hygiene and safe container development from environmental hormones, and needs a lot of support and attention to meet changes in food culture trends and demographic structure.
