  • BACKGROUND/OBJECTIVES: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS: This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS: Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS: A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.

  • This paper was done to verify the use of the Profile of Mood States (POMS) which was developed by McNair, Lorr, and Droppleman(1992) with modifications so that it is appropriate for Korean elders. Through the modified tool, it is possible to examine the mood of Korean elders and to contribute to the welfare of elders. The subjects were 370 elderly persons over 60 years old and the data for 319 persons(86%) were analyzed. The research tool was the POMS translated by Yun(1993) and corrected by the researcher. Data were collected between February 12 and April 9 in 1996 and analyzed using the SAS package. The result are as follows 1. Items with low Cronbach coefficient alpha which means low correlation with total items were removed. The items were removed : friendly, tense, considerate, relaxed, sympathetic, resentful, good-natured, rebellious, trusting, carefree. 2. Overlapped or ambiguous items were discussed by colleagues and elders through verification of con-tent-validity and were removed. Five items were removed in tense-anxiety, seven, in depression-dejection, three, in vigor-activity, three, in fatigue-inertia, two, in confusion-bewilder-ment, five, in friendliness, and six, in anger-hostility. Thirty four items remainined : angry, clear-headed, lively, confused, sorry, shaky, list-less, peeved, sad, active, blue, hopeless, spiteful, uneasy, unable to concentrate, fatigued, helpful, nervous, lonely, cheerful, bitter, exhausted, anxious, ready to fight, sluggish, helpless, alert, deceived, efficient, worthless, forgetful, terrified, vigorous, and uncertain about things. 3. Factor analysis was done in order to confirm construct validity and three factors were obtained from the result. The first factor, 'anxiety-depression' included 21 items, the second factor, 'vigor' included eight items, and the third factor, 'anger' included five items. Cronbach coefficient alpha for the 34 items was. 95. Based on the result, the following is suggested : 1. a contribute to elder's welfare can be made by examining Korean elder's mood in life. 2. there is a need to develop tools appropriate to Korean culture which can be used to examine elders' mood. 3. The modified POMS tool needs to be reverified with appropriate age groups and settings.

  • Checklist method is rapid and comprehensive to evaluate in practice. Check items are commonly rated by subjective utility function; i.e., evaluator's significant judgment. Since human judgment includes fuzziness (vagueness) inherently in spite of its significance, fuzzy set theory is useful in this case. The paper illustrates a evaluation method using fuzzy checklist where check items are rated as fuzzy numbers. Pairwise comparison data is used to determine the weights of check items, since it has comparative advantage for human's fuzzy judgment. Sample of BASIC program is provided for microcomputer. When uncertainty is due to subjectivity or imprecision of data, this method can be applied to practical problems widely.

  • BACKGROUND/OBJECTIVES: Happiness is an important factor in life, and food literacy (FL) has been emphasized as a core concept for a happy and healthy life. This study examined the level of happiness of Seoul citizens according to their sociodemographic factors and their association with FL. SUBJECTS/METHODS: This study used the data from the Seoul Food Survey, a cross-sectional study conducted on 4,039 Seoul citizens from September to October 2021. FL was measured using a validated questionnaire consisting of 33 items from 3 sub-domains: 14 items in the nutrition and safety domain, 8 items in the cultural and relational domain, and 11 items in the socio-ecological domain. Statistical analysis involved descriptive statistics and multivariate regression analysis. RESULTS: Various sociodemographic factors, such as household income, subjective health status, and food insecurity, were found to be associated with the level of happiness. The level of FL was also associated with the happiness scores. After adjusting for variables associated with happiness, the participants with the highest quartile FL scores were 7.32 times more likely to respond that they were happy than those with the lowest FL score. Three FL domains and total FL showed linear increases in overall happiness after controlling for subjective health status and sociodemographic factors (P < 0.001). CONCLUSIONS: After adjusting for the related covariates, higher levels of FL were associated with higher scores in happiness. Based on this study, it would be meaningful to evaluate ways to intervene in FL to improve the level of happiness among the general population.

  • Purpose - It has been argued that the regulations restricting entry and opening hours of General Super Markets and Super Super Markets have not been as effective as expected. In contrast, the win-win item scheme that appeared recently has the advantage that it could raise the effectiveness of the system in that win-win items are in principle resigned on the basis of bilateral agreements. This study analyzes the win-win item agreement made between Homeplus at Hap-jung and small traditional markets to examine the practical effectiveness of the win-win item scheme. While existing literature studying the regulatory effects have concentrated on the restrictions around store entry or opening hours of large retailers, it can be said that there have been few empirical studies on the effect of win-win items agreement with large retailers. Research design, data, and methodology - Homeplus at Hap-jung made a win-win items agreement with nearby small traditional market traders in 2013. In accordance with this voluntary agreement, Homeplus started by limiting its sales to 15 win-win items. The survey was conducted through one-on-one interviews, April 14 to May 2, 2014, by a professional public opinion research agency. The interviews were targeted at small business retailers in the nearby traditional market. We divided the traditional markets near Homeplus at Hap-jung where the win-win item agreement was achieved into two groups, win-win item agreement markets and non win-win item agreement markets, to compare the performance difference between the two groups. Results - To determine the change in sales of the 15 win-win items, we examined the performance difference between the two groups using two criteria (compared with similar items, and compared to sales volume a year ago). The results show that the individual sales of win-win items in the win-win item agreement markets are more likely to increase than in the non win-win item agreement markets. Total sales volume of individual stores in the agreement markets also showed a more significant increase compared to a year ago than those in non win-win item agreement markets. Conclusions - Contrary to the existing retail regulations that have one-sided and uniform characteristics, it can be pointed out that the win-win item scheme has the effect of increasing the success of the system itself because it is done on the basis of mutual agreement between General Super Markets and traditional markets. The empirical results of this study can be said to support this conjecture. For the successful settlement of a win-win items agreement, the following points should be reviewed. First, it requires a great effort from the selection process of win-win items in order to improve the effectiveness of the agreement. Second, the existing General Super Markets customers should be introduced to the traditional markets or small shops to increase the sales of win-win items. Therefore, voluntary effort is essentially required from the traditional markets to engage customers.

  • 본 연구의 3단계 선다형 평가 문항은 과학적 결과와 그 결과가 나온 과정 또 그러한 과정에 관계된 과학적 개념을 함께 물어 봄으로써 과학적 탐구 사고력을 의미있게 평가할 수 있고 객관식 문항형태이지만 객관식 평가의 단점인 추측의 요인을 주관식 응답에 준하여 거의 제거할 수 있다고 판단된다. 오랜 기간동안 1단계 4지선다형 또는 5지 선다형 시험에 익숙해 있던 학생들은 3단계 선다형 문항에 매우 적용하기 어렵겠고 교사들 또한 문항을 제작하는데 많은 시간과 노력이 필요하겠지만 평가가 학생들의 학습에 미치는 영향을 고려한다면 3단계 선다형 문항의 현장 도입은 절실히 필요하다. 이의 도입은 학생들의 탐구사고력의 신장에 큰 기여를 할 것으로 판단된다.
