Objectives: The objective of this study was to verify the validity of a mobile phone application (app) that applies a 24-hour dietary recall with meal photos, as a means of being a more accurate method of estimating dietary sodium intake. Methods: Of the 203 subjects enrolled, 172 subjects (84 males and 88 females) were selected for the final analysis, excluding those with an intake less than 500 kcal and urine output less than 500 ml. Dietary sodium assessment methods used for comparing with the 24-hour urinary sodium excretion are as follows: 1) face-to-face 24-hour dietary recall, 2) 24-hour dietary recall using the mobile app, 3) face-to-face 24-hour dietary recall considering liquid intakes from soup, stew, water kimchi and noodle, etc (liquid-based dishes), 4) 24-hour dietary recall using the mobile app considering liquid intakes from liquid-based dishes, and 5) food frequency questionnaire. Repeated ANOVA with Bonferroni method was used for comparing the average sodium intake, and Pearson's correlation was applied to correlate the methods used. Results: In women, no significant difference was observed in the average sodium intake between all methods. Moreover, analysis in men and total adults revealed no significant difference between the 24-hour urinary sodium secretion, and 24-hour dietary recall using the app and 24-hour dietary recall using the app considering liquid intakes. Sodium intake by food frequency questionnaire was significantly different when compared with the intake determined from 24-hour urinary sodium excretion. Sodium intake from all methods (except food frequency questionnaire) significantly correlated with values obtained from 24-hour urine sodium excretion. Conclusions: Results of this study validated a mobile phone app using a 24-hour dietary recall with meal photos to better estimate dietary sodium intakes. It is believed that further studies in the future will enable the application as a tool to more accurately determine sodium intake.

The purposes of this study are to analyze the problems of the elderly using kitchens by ergonomic work evaluation methods, and to make suggestions for planning and remodeling of the kitchens for the elderly. The work evaluation methods which used in this study were direct-observing methods, which contained the process of 2 or 3 times each visiting to four different houses where elderly people live. For direct-observing methods, analyzing with movement observations and observation methods with photos and videos were used. Characteristics of subject elderly people and problems of their kitchens were analyzed by static measurements, interviews, pictures, and videos. The data, which are recorded movements of the preparing meal of the elderly were analyzed by playing it back repeatedly. As results, physical characteristics of the elderly was the most important consideration; a participant with the arthritical knee was limping at the kitchen entrance due to the difference of the floor level, and a user with a bent back was working on the floor or place an elbow on the worktable to support her body. Those results made a conclusion about the common problems of the kitchens, and suggested the check list which has to be considered when designing the elderly using kitchen.

환대문화에서 비롯한 요식업 부문은 음식 쓰레기를 가장 많이 발생시키는 식품 부문이다. 지속가능한 서비스를 제공하기 위해 외식업계가 음식 낭비에 대한 문제를 이해하고 줄일 필요가 있는데, 이는 대부분 피할 수 있는 일이다. 기존 연구에서 음식물 쓰레기 행동의 동인과 제안된 완화 조치를 조사하였다. 그러나 난제를 해결하기 위해 서비스 디자이너는 혁신적인 솔루션을 고무할 수 있는 실행 가능한 통찰력이 필요하다. 본 연구의 목적은 두 가지이다. 첫 번째 목표는 음식점에서 젊은 소비자들이 음식을 남기는 행동에 영향을 미치는 요인을 파악하는 것이다. 두 번째 목표는 음식물 쓰레기 문제를 서비스 디자이너의 디자인 기회로 프레이밍(Framing) 하는 것이다. 국내 대학생 10명과 함께 사진 일기 (Photo Diary) 연구를 진행하였다. 참가자들은 두끼 식사의 전후 사진을 찍고 설문지를 작성하였다. 질문은 개인적인 배경과 식사 선택 시 고려 사항, 식사에 대한 만족도, 음식을 남기는 이유 등이다. 실험을 바탕으로 정성적 데이터와 정량적 데이터를 모두 수집하고 분석하였다. 그 결과 의식과 통제력 부족이 남은 음식물의 주요 동인이라는 것을 시사하였다. 서비스 디자인을 위한 음식물 쓰레기 문제는 "How Might We" 디자인 기회로 프레이밍 된다. 자신, 식사 파트너, 식당과의 의사소통을 개선하는 데 개입의 초점을 맞춰야 한다. 본 논문은 음식점 음식물 쓰레기의 예를 들어 난제를 프레이밍 하는 서비스 디자인 연구 접근 방식을 입증함으로써 이바지한다.
