Joo, Nami,Kim, Shin-Kyum,Yoon, Ji-young The Korean Society of Community Nutrition 2017 대한지역사회영양학회지 Vol.22 No.1

Objectives: The present study aimed to investigate high school students' sugar intake behaviors, the status of consuming sugary processed foods, the awareness of sugar, and the experience and interest in sugar-related education based on the level of sugar-related nutrition knowledge. Methods: In this study, five high schools were selected in Seoul, Korea, and a survey was conducted in 400 students on the level of sugar-related nutrition knowledge and sugar intake status. A total of 349 questionnaires were used for the final analysis. For statistical analysis, descriptive statistics was performed; a t-test, ${\chi}^2$ test, and Friedman test were used for comparative analysis. Results: The study results showed a positive association between the knowledge level of sugar and the appropriate sugar intake behavior and sugary food choices. The group with more nutrition knowledge on sugar was found to have good eating habits and to eat less sugary food. The main sources of sugar were beverages, confectionary, and bakery goods in the corresponding order, irrespective of the level of nutrition knowledge related to sugar. A significant difference was found in the groups' awareness of the sugar content of the drinks with 89.4% for the higher-knowledge group, and only 81.5% for the lower-knowledge group (p < 0.05). Results also showed that 43.9% of the higher-knowledge group and 36.4% of the lower knowledge group were interested in participating in education on sugar. Conclusions: This study result indicated the need to help adolescents to avoid excessive sugar intake from only certain favorite foods. Therefore, it is necessary to seek a systematic foundation for participatory education in order for them to maintain a low sugar intake in daily life and lead healthy eating habits by increasing their level of sugar-related information and knowledge.

Nami Joo(주나미),Sun-Mee Lee(이선미),Hee Sun Jeong(정희선) 동아시아식생활학회 2009 동아시아식생활학회지 Vol.19 No.3

This study was conducted to develop a recipe for a nutritional cookie containing Danggue powder, and to achieve an optimal ingredient composition and texture that would appeal to consumers of all ages. To reduce its content, wheat flour was partially substituted with Danggue in the formulation. Response surface methodology was used to analyze the measured results and showed 16 experimental points, including 2 replicates for the Danggue powder, brown sugar, and butter ingredients. The compositional and functional properties were measured, and these values were applied to a mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the final product. The sensory evaluation results indicated significant differences between samples for color (p<0.01), flavor (p<0.01), texture (p<0.05), and overall quality (p<0.05). As a result, the optimal ingredient levels for sensory quality were determined as 4.83 g of Danggue powder, 70.46 g of brown sugar, and 86.08 g of butter.

Nami Joo,Sanghyun Park,Bohee Lee,Jiyoung Yoon 한국영양학회 2015 Nutrition Research and Practice Vol.9 No.3

BACKGROUND/OBJECTIVES: The present study investigated Korean and Taiwan adults on the importance of and the satisfaction with street food sanitation and street food choice factor, in order to present management and improvement measures for street foods. SUBJECTS/METHODS: The present study conducted a survey on 400 randomly chosen adults (200 Korean, 200 Taiwanese). General characteristics, eating habits, street food intake frequency, and preference by type of street food of respondents were checked. Respondents’ importance and satisfaction of street food hygiene and selection attributes were also measured. In order to test for the difference between groups, χ²-test and t-test were performed. ISA was also performed to analyze importance and satisfaction. RESULTS: Results showed that the importance of sanitation was significantly higher than satisfaction on all items in both Korea and Taiwan, and the satisfaction with sanitation was higher in Taiwan than in Korea. According to ISA results with street food sanitation, satisfaction was low while importance was high in both Korea and Taiwan. In terms of street food choice factor, importance scores were significantly higher than satisfaction scores on all items. In addition, satisfaction scores on all items except ‘taste’ were significantly higher in Taiwan than in Korea. CONCLUSIONS: A manual on sanitation management of street foods should be developed to change the knowledge and attitude toward sanitation by putting into practice a regularly conducted education. Considering the popularity of street foods and its potential as a tourism resource to easily publicize our food culture, thorough management measures should be prepared on sanitation so that safe street food culture should be created.

Nami Joo,Stephany Sewon Hwang,Jiyoung Yoon 동아시아식생활학회 2018 동아시아식생활학회지 Vol.28 No.4

This study examined the consumers` environmental concerns regarding their green restaurant patronage intention. Questionnaires were distributed in the US and South Korea. Regarding the environmental concerns, only Korean consumers` cognitive environmental concern had a direct effect on the green restaurant patronage intention. It had a mediating effect on the route from behavioral environmental concern to green restaurant patronage intention among US consumers and from cognitive environmental concern to green restaurant patronage intention among Korean consumers. These findings suggest that it is important to encourage customers to dine green by emphasizing the importance of green consumption.

A Survey of American and Canadian's Food Purchasing Practices and Perception of Restaurant Patronage

Joo, Nami,Kennon, Lisa R. 한국식생활문화학회 2002 韓國食生活文化學會誌 Vol.17 No.2

본 연구는 한국에 거주하는 미국인 및 캐나다인의 식품구입 및 한국식당 이용실태를 조사한 결과 한국마켓에서의 식재료가 안전한지를 묻는 질문에 38%가 아니라고 응답하였고 77%가 음용수의 안전성을 확신한다고 대답하였으나 54%의 응답자는 수입된 물을 구입해서 마신다고 하였으며 한국음식을 상당히 좋아하고 한국음식점을 즐겨 찾는 것으로 나타났으며 한국음식의 단맛, 짠맛, spicy한 정도는 강하지 않다고 응답하였고 식당 종업원들의 위생관념에는 만족하지 않는 것으로 나타났다. 대부분의 응답자가 한국마켓에서 식재료의 안전도에 관해서는 신뢰하고 있었으나, 일부 응답자들은 본국의 음용수 및 음식을 가져다 먹는다고 응답한 것으로 보아 식재료에 대한 더욱 철저한 위생관리가 필요하다고 여겨지며, 또한 한국음식점 이용에 대한 질문에서도 전반적으로 좋은 반응을 보였으나 종업원의 위생관념의 부족을 지적한 바, 음식점에서의 위생분야에 더욱 주의를 기울여야 할 것을 지적하고자 한다.

Maternal Knowledge and Perceptions of Quick Service Patronage Regarding Children in South Korea

Joo, Nami 대한가정학회 2004 Family and Environment Research Vol.42 No.5

한국의 현대사회는 점차 산업화, 도시화 되어지고 있고 또한 경제가 성장함에 따라 외식산업이 점차 발달되어지면서 패스트푸드가 우리 식생활에서 차지하는 비중 또한 증가하는 추세이다. 이렇게 가족단위의 외식을 할 때 자녀들의 음식종류 결정권이 매우 크다는 점을 고려하고 14세미만의 어린이가 우리나라 전체인구의 21.8%를 차지하고 있는 점을 볼 때 패스트 푸드 산업에서 어린이들은 매우 중요한 고객이 되어질 수 있고 이러한 어린이들의 좋은 식습관 및 균형 잡힌 영양공급은 성인건강의 기초적인 요소라고 할 수 있겠다. 따라서 자녀들의 패스트푸드 소비에 관한 어머니의 견해를 조사함으로써 어린이들의 패스트푸드 소비를 바람직하게 유도하기 위한 방향을 제시하고 패스트푸드산업을 주도하는 생산자에게 기초자료를 제공하고자 Q-sort methodology로 본 연구를 실시한 결과, 패스트푸드점에서 가족들이 외식할 때 자녀들이 미치는 영향이 상당히 높음을 알 수 있었고 음식에 대한 어린 시절의 경험이 자녀들의 식습관, 기호도 발달, 바람직한 건강식품 선택에 매우 큰 영향을 미치므로 이때의 식품에 대한 올바른 지도가 필요하다고 어머니들은 생각하고 있었으며 패스트푸드점에서 아침식사를 하는 것은 매우 반대하는 견해를 가지고 있는 것으로 나타났다. The last half of the twentieth century brought many new opportunties and challenges to the traditional South Korean family. One area of change that challenges the traditional South Korean family is the availability of new food sources, specivically the introduction of commercial restaurants that offer new types of food in untraditional settings. This research investigated the perceptions of South Korean mothers'(n=104) regarding the patronage of quick service style restaurants by their children though the use of Q sort methodology. The results showed that even though children do influence the decision making process when determining where to eat away from home, Korean mothers still play a very prominent role in planning the family's food consumption. While Western food styles and practices can provide a variety of food selections determining where to eat away from home, Korean mothers still play a very prominent role in planning the family's food consumption. While Western food styles and practices can provide a variety of food selections and service styles, care should be taken not to over utilize the quick service restaurants' in place of traditional foods.

Optimization of Jelly Made with Rubus coreanus (Bokbunja) Using Response Surface Methodology

Nami Joo,Sun-Mee Lee,Hee Sun Jeong 한국식품영양과학회 2009 Preventive Nutrition and Food Science Vol.14 No.2

The purpose of this study was to find new applications for Rubus coreanus and to produce new products. Jelly prepared with Rubus coreanus was studied and analyzed with regard to its composition, rheology and sensory evaluation. The technique of response surface methodology was used to analyze the results, which showed 16 experimental points including 2 replicates for Rubus coreanus juice, gelatin and sucrose. Rheological characteristics such as lightness, redness, yellowness and hardness, springness, chewiness and gumminess were shown to be significant, and these were mostly influenced by the content of Rubus coreanus juice. Significant sensory characteristics such as color, flavor, transparency, taste and the overall quality were also found to be greatly influenced by Rubus coreanus juice and gelatin in general. Based on the overlapping categories of factors that satisfied all sensory categories, the maximally optimized point was taken as the middle point. This value was determined to be 43.28 g of Rubus coreanus juice and 9.19 g of gelatin for every 140.00 g of sucrose.
