Climate changes from global warming and reduction in agricultural land result in volatility of prices of agricultural products, causing a imbalance of food market in Korea. It is necessary to develop a transnational food industry cooperation system among Korea, China and Russia that directly or indirectly affect food industry in terms of the whole industrial network. This study analyzes the value chain and linkage in the agriculture, forestry and fisheries industries in three nations. The unit structure and the industrial patterns of three nations were derived using the World Input-output Table (WIOT) from 2004 to 2014 every five years. This paper is expected to contribute to develop food security cooperation in the northern part of the Korean peninsula and to promote the mutual growth of food industry through industry linkage and cooperation.

선행연구에서 얻은 alkalophilic Bacillus I-5 유래의 CGTase wild-type과 가수분해능이 강화된 mutant 효소를 활용하여 waxy rice starch로부터 아밀로펙틴 클러스터를 제조하였다. SEC-MALLS-RI 분석법으로 CGTase wild-type과 mutant 효소가 처리된 시료의 평균 분자량을 확인한 결과 10분가량의 효소반응으로 두 반응 모두 평균 분자량은 $10^4{\sim}10^5Da$으로 급격히 감소하였음을 확인하였으며, 일정 반응 시간이 경과한 이후에는 더 이상 분자량의 감소가 일어나지 않음으로 미루어 시료가 아밀로펙틴 클러스터 단위로 분해되었으며 그 분자량은 $10^4{\sim}10^5Da$ 정도임을 알 수 있다. 또한 MALDI-TOF/MS 분석을 통하여 CGTase wild-type은 다양한 종류의 cyclic 형태의 maltodextrin을 생성하고 있으며 mutant 효소는 주로 소량의 maltooligosaccharide 들을 생산함을 확인하였다.

As the number of households raising pets increases, the pet food industry is also growing. Since pets cannot express their intention explicitly, it appears that the owner's perception mainly affects the selection of products related to pets. In this study, consumers were categorized based on their interest in food choices and the factors influencing their interest in pet food were empirically analyzed. For the analysis, a cluster analysis, factor analysis, and Tobit analysis were conducted using consumer survey data for raising companion animals. The major findings of the study were as follows. As a result of the factor analysis and cluster analysis using questions for consumers' food consumption choices, consumer types were classified into high-interest, low-interest, and practical-seeking types. The degree of interest in pet food was high in the order of high-interest, practical-seeking, and low-interest type. Demographic characteristics such as gender, education, and household type correlate with differences in the degree of interest in pet food, and the food selection criteria of consumers also affect the degree of interest in pet food. These results show that consumers who are more interested in their food choices are more interested in pet food, and this will make possible to know pet owner's purchasing behavior for pet food.

BACKGROUND/OBJECTIVES: Excessive sugar intake is one of the causes associated with obesity and several chronic diseases prevalent in the modern society. This study was undertaken to investigate the effect of parenting variables based on the theory of planned behavior, on the sweetness preferences and sweets intake of children. SUBJECTS/METHODS: Parents and their children (n = 103, aged 5-7 years) were enrolled to participate in a survey for this study, after providing the required informed consent. Parents were asked to fill out a self-administered questionnaire at their residence. The sweetness preference test for children was conducted at a kindergarten (or daycare center) by applying the one-on-one interview method. RESULTS: The children were divided into two clusters categorized by the K-mean cluster analysis: Cluster 1 had higher sweetness preference (0.42 M sugar, 35%; 0.61 M sugar, 65%); Cluster 2 exhibited lower sweetness preference (0.14 M sugar, 9.5%; 0.20 M sugar, 9.5%; 0.29 M sugar, 81%). Cluster 1 had a higher frequency of sweets intake (P < 0.01), and lower sweets restriction (P < 0.05) and nutrition quotient score (P < 0.05). Sweets intake was negatively correlated with the nutritional quotient (r = -0.204, P < 0.05). The behavioral intention of parents was higher in cluster 2 (P < 0.05), while affective attitude, feeding practice, and reward were higher in cluster 1 (P < 0.001, P < 0.05, and P < 0.01, respectively). Furthermore, behavioral intention of parents showed a negative correlation with affective attitude (r = -0.282, P < 0.01) and feeding practice (r = -0.380, P < 0.01), and a positive correlation with subjective norm (r = 0.203, P < 0.05) and parenting attitude (r = 0.433, P < 0.01). CONCLUSIONS: This study indicates that the sweetness preferences and sweets intake of children is related to the parent's affective attitude, feeding practice and reward. We suggest that to reduce the sugar consumption of children, guidelines for access to sweets and pertinent parenting practices are required.

The purposes of this study were to classify consumer types and to analyze purchase behavior depending on food safety attitudes related to the Fukushima nuclear accident. Based on the consumer survey data, factor analysis and cluster analysis were done to classify consumer types. Applying factor analysis, six factors with a total variance of 73.4% were extracted from 22 basic variables. The 6 factors were termed 'anxiety from ingesting agricultural and fishery products after the nuclear accident', 'importance of food safety when purchasing food', 'reduced rate of purchases of agricultural and fishery products after the accident', 'importance of food prices', 'socio-demographic characteristics' and 'family composition'. Using cluster analysis, consumers were classified into 5 types using the factor scores of 6 factors. The main results are as follows. For every consumer type, the anxiety about imported agricultural and fishery products was higher than that for domestic products after the nuclear accident. The food safety attitudes of consumers were mainly formed by the socio-demographic characteristics. Consumer types with high-education and high-income responded flexibly to the food safety concerning the accident; especially, the consumer type with a high-income and kids under 19 responded very reasonably to the accident. However, consumer types with a low-income and aged over 50 or less than 30 years were the least responsive to the accident, mainly due to financial restrictions. Thus, we suggest some food safety strategies and policy implications based on consumer type for food safety after the accident.

The purpose of this study was to identify the differences of cognitive responses, emotional responses, customer satisfaction, and service loyalty about service encounter quality by types of restaurants and to analyse emotional responses, customer satisfaction, and service loyalty in accordance with level of service encounter quality. The questionnaire were collected from customers (N=812) who had used restaurants in Seoul, aiming at 15 or more-year-old customers from October 24, 2005 to November 6, 2005. The main results of this study were as follows: Statistically significant difference was showed in importance and performance of interaction quality, importance and performance of physical environment quality, performance of outcome quality depending on types of restaurants, while significant difference was not indicated in importance of outcome quality by types of restaurants. Positive emotional response was significantly high by types of restaurants in order of fine-dining restaurants, family restaurants, and fast-food restaurants, while negative emotional responses were significantly higher in fast-food restaurants than in the other two types. As far as Customer satisfaction are concerned, fine-dining restaurants showed higher customer satisfaction than the other two types. Attitudinal service loyalty was high in fine-dining restaurants, family restaurants and fast-food restaurants in order and behavioral loyalty was not significantly different with each type of restaurant. In accordance with level of service encounter quality, cluster analysis was conducted and the clusters were divided into 'high-valuation' and 'low-valuation'. 'High-valuation cluster' and 'low-valuation cluster' showed significant difference depending on types of restaurants that customers used(p<.001). The customers who used fine-dining restaurants and family restaurants valued the performance of service encounter highly. However, in fast-food restaurants, a lot of low-valuation customers existed. Therefore, fast-food restaurants have to improve performance of interaction quality, outcome quality and physical environment quality in service encounter. In addition, in 'high-valuation cluster' who valued service encounter quality highly showed higher scores in positive responses, customer satisfaction, service loyalty than in 'low-valuation cluster', and showed low negative responses.

Objectives: The present study was conducted to investigate associations between eating style and food intake of 45 female college students during Chuseok holidays. Methods: A ten-day food record was obtained and divided into two parts. The first five days (September 20-24, 2015) were considered as a 'Normal Day (ND 1-5)' and the subsequent five days (September 25-29) as 'Holiday (HD6-10)'. The middle three days (September 26-28) of the holidays were considered as the 'Peak Holiday (PD7- 9)'. Eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ) and anthropometry was assessed in all study participants. Participants were grouped by cluster analysis according to the mean energy intake of the first three days of the Holiday. Results: Participants had a low-normal range of BMI and they were carefully restricting their food intake at Normal Day. Even the food intake did not exceed 2000 kcal per day during the Peak Holiday. External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Normal energy and fat intake were correlated with the external eating subscale of the DEBQ. Restrained eating was associated with the weight, BMI, fat mass, waist, and hip girth of the subjects. Compared to the Normal Day, they overate during the Holiday with different eating styles including 'restraint', 'disinhibition', and 'fluctuation'. Therefore, neither eating behaviors nor anthropometry was associated with food intake during the Holiday. Although eating behaviors and anthropometric measures were not different among eating style clusters, the food intakes of disinhibition cluster were higher than those of restraint cluster during all the study periods. Conclusions: Subjects can be classified with the restraint, disinhibition, and fluctuation clusters. However, eating behaviors and anthropometry were not different among three clusters.

본 연구는 품종과 수확시기 및 발효조건에 따른 매실의 아미그달린 및 프루나신 함량분석을 통해 매실에 대한 일부 소비자 인식을 전환하고 매실의 적정 가공원료를 선정하는 것에 과학적인 근거를 설정하고자 진행하였다. 전 품종을 기준으로 매실의 아미그달린 함량은 종자가 과육보다 약 12.8배 높게 함유하고 있었으며, 종자와 과육에서 모두 5월 3일에서 5월 19일 사이 아미그달린 함량이 급격히 증가한 이후, 점차 증가폭이 줄어들었다. 일반적인 가식부인 과육 부분의 경우 선암매 품종이 모든 수확시기에서 가장 높게 측정되었는데, 가장 높은 수치인 34.7 mg(100 g 기준)은 기존 연구의 반수치사량($LD_{50}$)이 7,500 mg/kg(ICR계 마우스)이라는 것을 고려한다면 매우 낮은 수치였다. 매실의 섭취 방법 중 하나인 매실청을 제조하였을 때는 150일 이후 아미그달린이 거의 검출되지 않았다. 또한, 아미그달린과 프루나신이 점차 감소하는 데에 비해 매실의 성숙 또는 매실청으로 발효할 경우 시간이 지남에 따라 유기산 함량이 증가하는 것을 확인하였는데, 이는 아미그달린 및 프루나신 분해 효소의 활성에 영향을 미치는 것으로 추측할 수 있었다. 추가로 시판 중인 네 종의 과일에 대해 동일하게 분석을 진행한 결과, 자두와 복숭아, 포도에서도 아미그달린이 검출된 것을 알 수 있었다. 따라서 매실에 존재하는 아미그달린은 매실에만 존재하는 것이 아니며, 존재하는 아미그달린은 발효과정으로 충분히 제거할 수 있고 식품의약품안전처에서도 매실에 대한 독성사례 보고가 없는 것으로 미루어 볼 때, 그 위험성은 매우 미미하다고 판단된다. 따라서 매실의 독성에 대한 부정적인 인식을 전환하고, 매실에 존재하는 다양한 유효물질을 활용한 고부가가치 기능성 원료로서의 깊이 있는 연구가 활발히 진행되어야 할 것으로 생각된다.
