This study was conducted to compare of dietary behaviors of young and temporary workers with older and permanent workers of single-person households. A questionnaire survey was conducted by purposive quota sampling(n=566) by age groups(20~59 years old) and status of workers(temporary workers, permanent workers and business owners). Compared to other age groups, 20s had lower average monthly income and cost of eating-out, and they rarely cooked at home and mainly bought food and groceries at convenience stores(p<0.001). This pattern was similar to temporary workers compare to other groups. This study will be meaningful as a basic data for creating a healthy living environment for temporary workers and 20s of single-person households.

This study was conducted to analyze recognition, applicability, class satisfaction, and needs as well as students' attitudes for eating behavior by 1st and 3rd graders of a mixed middle school located in Gyeonggi area in relation to food and nutrition section of the Technology and Home Economics curriculum and thereby provide basic data for development of strategies of educational effect maximization of food and nutrition in the curriculum. 522 questionnaire were collected and statistically processed. Findings from this study are as follows. Both 1st and 3rd graders were found to exhibit relatively low preference for technology and home economics curriculum. While 1st graders were more interested in the subject than 3rd graders, the frequency of practical use of the food and nutrition section in every day life was higher in 3rd graders than that in 1st graders. For food and nutrition section of the subject, preference level of the 1st graders was higher than 3rd graders. The 1st graders were higher than 3rd graders in the needs for food and nutrition section as well as in usefulness in every day life of the unit. The applicability in every day life of the unit was found to be generally higher, with 1st graders having a higher level of applicability than 3rd graders (p<0.001). Class satisfaction of the unit was higher in 1st graders than 3rd graders, with the most satisfactory unit being 'basics and practice of cooking' both for 1st and 3rd graders. Needs for food and nutrition unit were higher in 1st graders than 3rd graders, with the unit highly needed being 'basics and practice of cooking' both for 1st and 3rd graders. Regarding interrelation of the degree of preference, need, applicability and class satisfaction, as the preference was high on food and nutrition, the degree of need, applicability, and class satisfaction was high. As respondents recognized food nutrition section necessary, they were more satisfied and showed high applicability for the section. Therefore, contents of food and nutrition section should be improved with re-organization of educational and subject contents so that they will be best fit for students by grade, to increase preference, applicability and necessity in every life. In addition, to maximize the applicability of the subject in everyday life, sufficient class-time should be assigned for the purpose of experiment- and practice-based education, and a wide range of teaching strategies are needed to increase students' interest in the subject.

Purpose: Given that the indicators related to chronic diseases are important to evaluating goals of the national health policy, the aim of this study was to develop dietary behavior items available in the Korea National Health and Nutrition Examination Survey. Methods: The dietary behavior items were developed based on the literature reviews, need assessment of the field, expert focus-group interviews, and expert advisory meeting. Questions for each dietary behavior item were developed by reflecting on environmental, personal, and behavior factors of the ecological frame and then revised through expert focus-group interview and expert advisory meeting. The understanding and reliability of the developed questionnaire were assessed by cognitive interview and test-retest reliability. Results: The developed items were sodium and salt intake, added and simple sugar intake, enough time to consume a meal for all ages, caffeine drinks and fresh/healthy food intake for children and adolescents, and limited dietary intake, fresh/healthy food intake for seniors. In most questions except some questions on sodium and salt intake, subjects understood over 70% and consistency of responses based on the kappa values was acceptable. Conclusion: Developed dietary behavior items are expected to be useful for evidence-based nutrition policy, interventions and research targeting dietary patterns through investigating and monitoring dietary behavior patterns.

오늘날 최신 의료기술 및 과학의 발달로 인간의 수명이 연장되는 것에 비해 암 발생률은 세계적으로 증가추세에 있다. 암은 인류의 1/3을 사망하게 하는 주요원인으로 인류공동의 관심사이며 온 세계의 과학자나 의학자들에게 주어진 최대 과제이기도 하다. 암발생률과 사망률을 국가별로 살펴보면 미국의 경우 1년에 약 1백만명 정도가 암에 걸리고 그 중 약 45만명 정도가 암으로 사망하고 있는 것으로 보고되고 있으며 일본은 1981년부터 사망 원인 1위가 암으로 밝혀진 후 연간 약 22만명 정도가 암으로 사망하고 있다. 우리 나라 역시 1988년부터 암이 병인별 사망원인 1위가 된 후 최근 1995년에는 인구 10만명당 1413명이 암으로 사망하고 있는 것으로 나타났다. 암의 발병원인은 여러 가지가 있지만 유전적인 요소와 같은 내적 요인보다는 환경적 요인에 의한 발행이 더 큰 원인이 되고 있으며 환경적 요인 중에서도 매일 반복해서 섭취하는 음식물은 매우 중요한 부분을 차지하고 있다. 따라서 우리의 일상적인 식생활에 좀 더 주의한다면 암의 원인이 될 수 있는 식사를 암을 예방할 수 있는 식사로 바꿀 수 있을 것이다.

This study was conducted to assess meal management and nutrient intake of 357 elderlies in Ulsan. 114 male and 243 female elderlies over 65 year old were recruited from July 5 to August 13, 1995. Questionnaires for general characteristics of the subjects(such as family size, living cost, pocket money and health condition) and for meal management were used. The levels of depression and anxiety were measured by CED-S and Spielbuger's STAI-S, respectively In addition, nutrient intakes were conducted by convenience methods. Nutrient intake of male and female showed the average daily intake of energy, Protein, vitamin A, vitamin $B_2, $ and vitamin C were lower than Korean recommended dietary allowances(RDA). But other nutrient intake were higher than RDA except that calcium intake of female was lower. Most nutrient intakes were positively correlated with family size, living cost, pocket money and health condition. Depression and anxiety scores were also negatively correlated with most of nutrient intakes. The pattern of meal management could predict nutrient intakes as expected : regularity and pleansantness of eating were positively correlated with nutrient intakes, whereas unbalanced meal and eating lonely were negatively correlated with them.

Purpose: With the 2021 revision of dietary guidelines in Korean emphasizing environmentally sustainable dietary practices, this study attempted to develop an evaluation tool to comprehensively evaluate the degree of practice and compliance with food and nutrient intake, dietary habits, and dietary culture guidelines based on the revised dietary guidelines. Methods: The candidate evaluation items were collected by reviewing 934 literature reviews on domestic and foreign dietary evaluations. Fifty-nine candidate items were derived by selecting the items corresponding to dietary guidelines. The content validity ratio (CVR) cutoff point evaluation was conducted with 11 experts to delete 11 items that did not meet the CVR standard. Fifty-five pilot survey candidate items were selected through revision and additional process according to expert opinion. Seventy final candidate items were selected by adding 15 questions for validity verification and reference. A pilot survey was conducted online and offline on 332 adults aged 19-64 in Seoul and the metropolitan area, and exploratory factor analysis was used to verify the construct validity of the evaluation items. Through exploratory factor analysis, the Kaiser-Meyer-Olkin, Bartlett's sphericity test, variance explained, and Cronbach's alpha criteria were confirmed in each process. Results: Exploratory factor analyses derived three criteria: food and nutrient intakes (11 items), eating behaviors (9 items), and dietary culture (14 items), consisting of 34 evaluation items. Conclusion: The present scale was validated and can be used for comprehensive evaluations of the dietary guidelines for Korean adults in a simple way.

The main purpose of this study was to develop teaching and learning plans and a smart textbook for food and nutrition education in Home Economics focusing on 'healthy diet and meal plans' unit in "Technology home Economics" textbooks for 7th graders to evaluate the effectiveness of the instruction conducted with the smart textbook. The content of the study to achieve the purpose is as follows: First, design a smart education-based teaching and learning curriculum for food and nutrition education in Home Economics, focusing on 'healthy diet and meal plans' unit. Second, develop a smart textbook for food and nutrition education based on the teaching and learning curriculum, using a smart content authoring tool. Third, evaluate the effectiveness of the instruction after applying the curriculum in real classroom situations. The results of this study were as follows: First, teaching and learning plans and materials were developed for two units, 'issues regarding teenagers' diet' and 'implementation of a healthy and balanced diet', under 'teenagers' life'. The first unit, 'issues regarding teenagers' diet', dealt with topics such as teenagers' dietary behaviors, nutrition, and health. Learning objectives for this unit were to help students identify and evaluate their own dietary behaviors. The second unit, 'implementation of a healthy and balanced diet', encouraged students to diagnose problems with their diet and plan nutrient rich meals. The objectives for this unit were to help students implement a healthy and balanced diet by providing them with nutrition and dietary guidelines for Koreans, sample meal plans, and guidelines for developing healthy eating habits for teenagers. In order to develop a teaching and learning plans to achieve these objectives, teaching and learning materials including inquiry tasks, materials for group activities, multimedia, applications and various pop-up learning materials were developed. Second, a smart textbook using DocZoom, which was a smart content authoring tool was developed. The textbook dealt with issues regarding teenagers' diet and implementation of a healthy and balanced diet. Multimedia material used in the textbook come from the Ministry of Food and Drug Safety's food and nutrition education web sites and other sources. To develop student-oriented material, relevant video clips were added to the smart textbook to motivate students and enhance their interest in the course. Third, the outcome of this study indicated that the instruction using teaching and learning plans and learning materials with the smart textbook was effective for enhancing students' interest in Home Economics classes (t-value=-3.99, p<.001), creating enthusiasm for learning(t-value = -2.61, p<.05), encouraging self-directed and independent learning(t-value = -4.77, p<.001), and improving students' interest in food and nutrition courses(t-value = -3.83, p<.001). The students' evaluation of the instruction were as follows: the instruction using teaching and learning plans and learning materials with smart textbooks, instead of paper textbooks, helped them save time looking for learning materials; students evaluated that it was easier for them to see and understand video clips and charts. In addition, most students answered that instruction with smart textbooks were more fun and convenient, and they agreed that the courses enhanced their learning experience.

This study analyzed and verified the effects of a dietary education program for Korean young adults in single-person households. The dietary education program was conducted for five weeks (from November 10 to December 8, 2020) for Korean young adults in single-person households living in Seongbuk-gu, via four face-to-face education sessions and one online education session, including both theoretical lectures and practice. The effect of the dietary education program was analyzed through the Nutrition Quotient (NQ) questionnaire for adults provided by the Korean Nutrition Society, a dietary evaluation checklist questionnaire developed by the researchers, and photovoices. The average of 'Nutrition' score increased from 51.81 to 53.20, but there was no statistically significant difference. However, there was a significant change in the 'Moderation' category (p<0.05). As for the researcher-developed dietary evaluation, the average of the 'Importance' area rose from 3.77 to 3.99, but there was no statistically significant difference. The average of the 'Practice' area rose from 3.03 to 3.57, significant results were found (p<0.05). When the pre-/post-tests were compared by the sub-categories, four elements of 'Importance', i.e., balanced meals and avoided foods, and all five elements of 'Practice' were significantly improved (p<0.05). A total of 200 photovoices were analyzed according to Social Cognitive Theory. As a result of the analysis, the deterrents that help people eat healthy homemade food were 48% environmental factors, 30% behavioral factors, and 22% individual cognitive factors. The deterrents found to hinder participants from eating healthy homemade food were 72% environmental factors and 14% individual cognitive and behavioral factors. The results suggest that the dietary education program for Korean young adults in single-person households can be an effective tool that promotes self-motivation, behavioral changes, and improvements of the surrounding environment.
