최근 현대인들은 풍족해진 먹을거리에도 불구하고, 특정 영양소의 과잉 및 부족 섭취로 영양불균형의 문제로 겪고 있다. 이에 따라, 건강 및 식단조절에 관한 관심이 증가하였고, 다양한 모바일시스템을 이용한 어플리케이션들이 등장하였다. 하지만 대부분의 어플리케이션들은 섭취한 식단을 기록하고 단순한 통계를 보여주는데 그치는 수준이며 건강 식단을 위한 일반적인 정보를 제공한다. 건강에 관심 있는 사용자에게는 실질적으로 본인의 음식 선호를 반영하거나 맞춤형 권장 정보를 제공하는 추천서비스가 필요하다. 따라서 본 연구에서는 사용자의 신체 및 활동조건에 따른 권장섭취열량에 대해 식품군별 교환단위수를 부여하고, 과거 섭취이력을 활용하여 음식 선호를 분석하여 식품군별 권장섭취 단위수를 만족하는 식단추천 기법을 제안한다. 또한 실험을 통하여 사용자의 선호만을 고려한 경우, 권장교환단위만을 고려하는 경우와 비교하여 정밀도, 재현율, 건강지수, 그리고 3지표의 조화평균을 도출하고 제안하는 알고리즘의 우수성을 증명하였다. 해당 기법을 활용하여 사용자는 본인의 선호를 반영하는 맞춤형 건강식단을 추천받을 수 있으며 이를 통해 건강한 식습관 개선 및 유지에 도움을 줄 수 있다.

인터넷과 대중매체의 발전은 새로운 다이어트에 대한 사람들의 접근을 용이하게 만들었다. 그러나 사람들의 관심은 시시각각으로 변화하기 때문에 이슈가 되는 다이어트는 매년 달라지고 있다. 따라서 본 연구에서는 2016년의 다이어트에 대한 경향을 알아보고 분석하기 위해서 빅데이터 분석 방법을 이용하였고, 포털 사이트 네이버를 통해 2016년 1월 1일부터 2016년 12월 31일 까지 1년간 다이어트 키워드가 포함된 문장을 수집하고 분석하여 단순빈도 분석, N-gram 분석, 키워드 네트워크 분석, 계절성 분석을 시행하였다. 단순빈도분석을 통해 가장 많이 출현한 키워드는 '운동'으로(191,032개)나타났고, 그 다음으로 '식단'이(102,631개)로 나타났으며, 키워드 간의 연관빈도를 분석한 N-gram 분석결과 상위 결과로 다이어트-식단, 다이어트-시작, 다이어트-성공으로 나타났고, 다이어트-도시락이 새롭게 나타나 다이어트 시장의 새로운 변화를 확인할 수 있었다. 또한 다이어트 키워드와 연관된 키워드를 유사한 성격들끼리 그룹화한 키워드 네트워크 분석을 통해 식이그룹, 운동 그룹, 상업적 다이어트 식품, 상업적 다이어트 프로그램 그룹으로 총 4개의 그룹으로 세분화되었다. 계절성 분석을 통해 2월부터 7월까지 꾸준한 상승을 보였으나, 10월에 다이어트 출현빈도 수치가 급격히 상승하였고, 대중매체를 통해 소개된 고지방 다이어트의 월별 출현빈도도 10월에 급격한 상승이 있었다. 따라서 대중매체의 영향이나 새로운 다이어트의 유행이 사람들에게 큰 영향을 미치는 것을 확인할 수 있었다. 이상의 결과를 바탕으로 다이어트의 패턴은 1년을 기준으로 일정한 양상을 띠고 있으나, 새롭게 유행하는 다이어트의 출현을 통해 사람들의 관심이 변화하여 다이어트의 패턴에도 영향을 미치는 것을 확인하였다. 결국 시시각각 변화하는 다이어트를 빠르게 파악하기 위해서는 주기적이기 보다는 지속적인 모니터링과 분석이 필요하다고 판단되어진다.

This study was undertaken to examine the dietary adaptation in Korea, and utilization of university foodservice (UF), according to the nationality of foreign students. The survey was conducted from April to June in 2017, and included 604 subjects studying in a university in Busan. The questionnaire was designed to examine the adaptability to Korean food and the consumption of UF. The nationalities included students from China (63.4%), Vietnam (13.2%), Central Asia (8.9%), Southeast Asia (5.0%), and others (9.4%). Vietnamese and Southeast Asians showed higher adaptation to Korean food than Chinese or Central Asians. The degree of contribution of UF to diet was highest amongst the Chinese, followed by Vietnamese. The main reason for not consuming UF for the Chinese and Southeast Asians was 'lack of menu variety', and for Central Asians was 'no menu that can be eaten, including due to religious reasons'. In order to improve UF, all groups asked for increased 'variety of menu', and Vietnamese and Southeast Asians also asked for 'decrease in price'. In meat, fish, and vegetable menus, there were significant differences in the types and recipes of foods preferred, as per the nationality. These results indicate that different approaches by considering the national characteristics are required, to help international students adapt to Korean food, and to increase their consumption of UF.

Objectives: Study purpose was to investigate perception on diet, diet problems and related factors among young adult women using focus group interviews (FGI) based on the Social Cognitive Theory (SCT). Methods: Eight groups of FGI were conducted with 47 female undergraduate or graduate students. Guide for FGI included questions regarding perception on optimal diet, diet problems and cognitive, behavioral, and environmental factors of SCT. FGI were video, audio-taped, transcribed and analyzed by themes and sub-themes. Results: Subjects showed irregular eating habits (skipping breakfast, irregular meal time) and selection of unhealthy foods as the main diet problems. Regarding cognitive factors related to optimal diet, subjects mentioned positive outcome expectations (e.g., health promotion, skin health, improvement in eating habits, etc.) and negative outcome expectations (e.g., annoying, hungry, expensive, taste). Factors that promoted optimal diet were mainly received from information from mobile or internet and access to menu or recipes. Factors that prevented optimal diet included influence from friends, lack of time and cooking skills. Behavioral factors for optimal diet included behavioral capability regarding snacks, healthy eating and smart food selection. Subjects mentioned mass media (mobile, internet, TV) as the influential physical environment, and significant others (parents, friends, grandparents) as the influential social environment in optimal diet. For education topics, subjects wanted to learn about healthy meals, basic nutrition, disease and nutrition, and weight control. They wanted to learn those aspects by using mobile or internet, lectures (cooking classes), campaign and events. Conclusions: Study results might be used for planning education regarding optimal diet for young adult women. Education programs need to focus on increasing positive outcome expectations (e.g., health) and behavioral capability for healthy eating and food selection, reducing negative outcome expectations (e.g., cost, taste) and barriers, making supportive environments for optimal diet, and incorporating topics and methods found in this study.

The purpose of this study was to investigate the inpatients' perception of therapeutic-diets and of explanation about those diets provided by hospitals and satisfaction on therapeutic-diets at hospitals in Busan. The subjects consisted of 155 inpatients at five hospitals, which all had over 400 beds. The research was performed through the interviewing process using questionnaires. Seventy five percent of patients had received an explanation for their therapeutic-diet and 57.4% of respondents were given a manual that explained the reason for the therapeutic-diet. The professionals who explained the therapeutic-diet was 61.7% dietitians and 25.6% doctors. 59.4% of the patients considered the dietitian to be suitable for explaining the diet and 25.6% patients believed the doctor to be suitable for explaining the diet. In terms of the patients' perception of the therapeutic-diet explanation, 74.5% of the patients understood very well, 78.9% of them perceived this explanation as very important, and 67.5% of them were satisfied. On a scale of 5.00 for therapeutic-diet satisfaction, the average scores were 2.95 for meal characteristics and 3.06 for service characteristics. The items that scored low in therapeutic-diet satisfaction were taste, seasoning and appearance of meals, provision of selective menu and consideration of personal preference. In terms of the perception of understanding the therapeutic-diet, patients who were provided a manual and an explanation gave high scores to 'taste', 'variety of diet', 'meeting opportunity with dietitians', and 'prompt dealing with meal complications'. There was a significant (p<0.05) positive correlation between satisfaction for the explanation of the therapeutic-diet and the degree of perceived benefits of the explanation to the nutrition-management and the satisfaction on the therapeutic-diet satisfaction. Therefore, the results of this study suggest that hospitals should increase support for explaining the therapeutic-diet by dietitians and develop menus based on the patients' preference and the taste of the meal.

The purpose of this paper is to develop the software for the diagnosis and evaluation of the nutritional ingestion status of inviduals or a group of family members who have inhabited in rural and urban, based on the suggested amount of nutrition and foods. This software can be used for the computation for the needed amount of nutrition, which is suitable to the economic conditions of individuals and group of family members, and for the reduction of effort to plan the balanced table menu and effort to manage the diets. However, those commercial softwares were hard to be purchased and expensive for the users, and even if they were purchased, it needs much time and efforts to operate and run the program. Especially those commerical software were not possible to revise when the user has faced with the need to revise and complement the input data according to his situations such as the individuals and the group of family members. The software which was developed to treat the table menu and the nutrition was very limited to the particular persons. That is, the software was not for the evaluation of the nutrition synthetically and reasonably, because it was planed to use for the patients and the group of hospital and research centers. However this software has a merit of providing the table menu and the nutritional diagnosis in that it can show the suggested amount of nutrition, the evaluation of nutrition, the methods of diet, and management of nutrition individually according to the age, sex, amount of exercise, and experience of sickness. The expected effect can be predicted to calculate the lacking amount of nutrition which the individual has taken, and be provided to the suitable table menu. In addition to this, the various table menu is based on the foods which can be purchased easily and inexpensively at any times.

Ten healthy wome 2-~25 years participated in a 5-week metabolic study to investigate the daily riboflavin requirement of Korean women. Three daily menu and meal patterns were used. Low riboflavin(LR) diet provided riboflavin at a level of 0.71mg / 1000Kcal based on food composition table. High riboflavin(HR) diet provided 1.14mg / 1000Kcal. The riboflavin status was assessed by erythrocyte glutathione reductase activity coefficient(EGRAC) and urinary exretion of riboflavin. Mean EGRAC of LR period and HR period were 1.17+0.08 and 1.01+0.03, repectively. There were discrepanices of riboflavin content of experimental diet between chemical analysis and calculation by Korean food composition table. Urinary riboflavin excretion of subjects was acceptable over the whole study period. It appeared that 0.71mg / 1000Kcal is requirement of riboflavin to maintain EGRAC withing normal range. Thus, it is suggested that current recommendation of 0.6mg / 1000Kcal of riboflavin intake may not be adequate as RDA level in Korea.
