In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.

본 논문에서는 TV 프로그램 <한끼줍쇼>를 통해 보여주고자 한 한국인의 정서, 문화, 음식을 이야기하고자 한다. 한국 사회는 그동안 급격한 산업화의 영향으로 도시화가 빠르게 진행되어 왔다. 그로 인해 현대인의 모습은 컴퓨터와 모바일 폰을 친구 삼아 지내거나 식사시간을 넘겨서 혼자 식사를 해결하는 등 단출하고 분주한 생활을 보내고 있다. 이제는 예전처럼 단란하게 가족끼리 저녁을 먹으며 즐겁게 얘기 나누는 것이 이제는 흔치 않은 풍경이 되어 버렸다. 앞으로 4차 산업으로 나아가는 시점에서 한국 사회는 개인주의, 소외된 삶이 가속화될 것이다. 이 시점에서 우리 가족과 이웃을 돌아보며 무엇이 더 소중한지를 자 한다.

The purpose of this study was to analyze information about food and nutrition presented through the television broadcast media, with the aim of finding out the optimal communication method for supplying the general public with accurate information. To perform this study, a total of sixteen monitoring people were recruited and trained before and during the study. Five domestic TV channels were selected to be monitored, and the total monitoring period was six months. For maximum efficiency, the monitoring people were assigned to 8 teams. The results of the present study can be summarized as follows : First, the total reported cases of information about food and nutrition were 237, of which about 30% were judged appropriate and 70％ as inappropriate. Second, classifying each case by program type, information programs made up the highest portion at 82 cases (34.6%), cooking programs accounted for 76 cases (32.1%), news programs for 40 cases (16.9%), and entertainment programs for 7 cases (3.0%). The analysis showed that the greatest amount of incorrect information was found in dramas, followed by entertainment, information, cooking and news programs. Third, classifying each case by theme of contents monitored, meal preparation and cookery made up the highest portion at 86 cases (36.3%), foods accounted for 67 cases (28.3%), disease and diet-therapy for 40 cases (16.9%), eating habits for 31 cases (13.1%), and diet and fitness for 13 cases (5.5%). Incorrect information was conveyed most often on the themes of food habits, foods, disease and diet-therapy, cookery, and diet and fitness. Fourth, classifying each case by channel, Cable TV had the highest frequency at 72 cases (30.4%), MBC had 51 cases (21.5%), SBS had 43 cases (18.1%), KBS1 had 41 cases (17.3%) and KBS2 had 30 cases (12.7%). In conclusion, systematic monitoring should be continued to reduce the frequency of incorrect information being broadcast and to help ensure that accurate information is conveyed to the general public. Moreover, there should be a system of cooperation to provide information to help broadcast production teams establish a strategic program. Finally, it is essential to organize an advisory team by promoting links between the mass media and specialists in the field, and to develop an educational program on nutrition to help ensure the communication of accurate information on food and nutrition.

Although motivation and information search have both been studied continuously and separately as important marketing strategies, the relation between cause and effect has received little research attention. Therefore the objective of this study was to research the causal relationships between motivation and information search method. Frequency analysis and reliability analysis, factor analysis, and SEM(Structure Equation Model) were adopted to analyze the data. Motivation was divided into 5 factors which significantly influenced information search method. Factor 1, 'Reception and congratulation', influenced information search positively through 'newspaper, magazine', and 'word of mouth' but negatively through 'TV-advertising' and 'Flyer, Press copy'. Factor 2, 'Change of dietary life', influenced positively 'TV-advertising'. Factor 3, 'Economic saving', influenced positively 'newspaper, magazine', and 'the e-mail's advertising' Factor 4, 'Preference motivation', influenced negatively 'word of mouth' Factor 5, 'Advertisement and companion's need', influenced positively 'newspaper, magazine', and 'the e-mail's advertising' but negatively 'TV-advertising' As a result, customers appeared to choose various information search methods according to their eating-out motivation. 'The e-mail's advertising', and 'word of mouth' are popular among customers' information search methods. Therefore, food-service corporations need to try eliminating negative images of various advertisements and activate positive word of mouth marketing, promotion through internet.

This study was performed to test the feasibility of thermophilic ($55^{\circ}$) co-digestion of municipal sewage sludge and food wastes. The management variables of co-digestion were the mixed ratios of municipal sewage sludge and food waste hydraulic retention times (HRTs). During the operation of thermophilic co-digestion, the reactor pH ranged from 7.0 to 7.5 and the reactor alkalinity remained above 3,200 to 4,000 mg/L as $CaCO_3$. The volatile fatty acids concentration increased as the HRT shortened from 20 days to 10 days and the mixture ratio increased to 1:4, but did not reach toxic levels for co-digestion of sewage sludge and food wastes. Methane productivity increased gradually as the organic loading rate increased. Maximum methane productivity reached 1.03v/v-d at an HRT of 10 days and at the mixture ratio of 1:4. The TVS removal efficiency decreased from 70.6% to 58.3% as the HRT shortened from 20 days to 10 days. TVS removal efficiency ranged from 57.0% to 77% during the entire operation. It is likely that thermophilic co-digestion of sewage sludge and food wastes is a very effective method both to environmentally treat food waste and to economically produce gas for energy.

Purpose: Various forms of distraction can have different effects on food intake. Distraction can draw attention away from the food being consumed and inhibit monitoring of food intake This study examined the effects of different levels of distraction on eating behaviors. Methods: The study was conducted using a repeated-measures design. The participants (10 males, 13 females) were served test meals (curry rice, 800 g) with the same volume at lunch for 4 weeks. The eating behaviors were analyzed during 4 distraction sessions: first session (without distraction), second session (audio distraction, radio), third session (audiovisual distraction, television), and fourth session (audiovisual distraction and hand-use, smartphone). The satiety ratings were measured using a 100 mm visual analog scale. Results: The participants consumed more food during the fourth session than during other sessions. In addition, the mealtime duration in the fourth session was longer than that in the other sessions (audiovisual distraction and hand-use, 13.74 minutes vs. without distraction, 10.36 minutes; audio distraction, 8.31 minutes; and audiovisual distraction, 9.61 minutes; p < 0.05). As the satiety ratings obtained before and after consumption of the test meals in each distraction session, participants felt significantly more satiated 30 minutes after consuming the test meal in the first session than they did in the other distraction sessions (without distraction, 84.23 mm vs. audio distraction, 76.07 mm; audiovisual distraction, 68.93 mm; and audiovisual distraction and hand-use, 74.70 mm; p < 0.05). Conclusion: Different levels of distraction can have different effects on eating behaviors and when distractions become diverse and selectable, food intake may be affected by distraction.

본 연구에서는 소셜미디어 콘텐츠를 소프트웨어 시스템을 이용하거나 정성적으로 분석함으로써 L-글루타민산나트륨에 대한 소비자 인식도를 조사하고자 하였다. 첫 번째로, 1년 (2013.7~2014.6)의 기간 동안 네이버와 카페에서 작성된 글들을 수집하였으며, 수집한 문서들을 무료 텍스트 분석 소프트웨어인 TONK를 사용하여 분석하였다. 블로그와 카페에서 작성된 글들은 주로 L-글루타민산나트륨의 사용과 관련된 음식점 후기 및 MSG (L-글루타민산나트륨)-무첨가 제품에 대한 홍보 내용을 담은 글들로 파악되었으며, 기타 L-글루타민산나트륨의 안전성 또는 식품첨가물 제거법에 대한 내용으로 파악되었다. 두 번째로, 네이버 트렌드 검색 서비스를 이용하여 L-글루타민산나트륨에 대한 검색량 증가 구간에 발생한 언론보도 사건을 조사하였다. PC 검색량의 경우 총 5개 증가 구간 중 3개의 구간에서, 모바일 검색량의 총 9개 증가 구간 중 6개의 구간에서 시사 프로그램에서 L-글루타민산나트륨에 대해 보도한 것으로 나타났다. 나머지 구간에서는 일간지나 TV 뉴스로 기사를 보도한 구간들로 나타났다. 세 번째로 식품의약품안전처의 L-글루타민산나트륨의 안전성 발표를 보도한 연합뉴스의 댓글을 분석하였다. 공감수 100개 이상인 댓글의 내용을 분석한 결과, L-글루타민산나트륨의 안전성, 질 낮은 재료의 사용 지적, MSG (L-글루타민산나트륨) 과다사용에 대한 우려, 정부 불신을 표현하는 댓글들이 파악되었다. 시판 제품들의 표시사항을 분석한 결과, 일일섭취허용량을 설정할 필요가 없을 정도로 안전한 식품첨가물임에도 불구하고 L-글루타민산나트륨을 첨가하지 않은 제품들은 L-글루타민산나트륨 무첨가라는 표시를 강조하고 있는 것으로 조사되었다. 이는 국가기관, 교육청과 지방자치단체에서 MSG 미사용을 원칙으로 제도를 운용하고 있어 이러한 정책이 산업계와 소비자 인식에 영향을 미쳤을 가능성도 고려해볼 수 있다. 본 연구 결과 소비자들은 대체로 소셜 미디어를 이용하여 검색하거나 관련 제품을 구매하고자 할 때 L-글루타민산나트륨을 사용하지 않는 것이 좋다는 인식을 하게 될 가능성이 있는 것으로 파악되며, L-글루타민산나트륨의 과다 사용에 관심이 있는 것으로 나타났다. TV 시사 프로그램에서 방송하거나 일간지 또는 TV 뉴스에서 기사를 보도할 경우 네이버 검색량이 증가하였으며, 검색량 증가구간은 PC 환경에서보다는 모바일 환경에서 더욱 증가하는 것으로 나타났다. 따라서 L-글루타민산나트륨과 관련한 커뮤니케이션 수단으로 소비자들이 관심있어 하는 방송프로그램, 뉴스 프로그램 등 언론을 활용하고, PC보다는 모바일을 통하여 소비자에게 접근한다면 효과적으로 소비자에게 정보를 전달할 수 있을 것이다.
