국내 음식부산물 발생량은 연간 약 500만톤으로 그 중 70 %가량은 퇴비화 또는 사료화로 자원화되고 있다. 최근 비료공정규격상 음식부산물 건조분말(DFP)이 혼합유기질비료 및 유기복합비료의 원료로 사용할 수 있게 되었지만 아직 적정사용기준에 대한 설정이 미흡한 상태이다. 이에 본 연구는 수집 시기별 음식부산물 건조분말의 화학적 특성을 평가하고 음식부산물 건조분말이 혼합된 혼합유기질비료의 사용량에 따른 작물 및 토양화학성 변화에 대해 평가하고자 하였다. 처리구는 무처리(NF), 무기질비료처리구(NPK, N-P2O5-K2O=32-7.8-19.8 kg 10a-1), 음식부산물 건조분말 단독처리구(DFP), 시판혼합유기질비료(MOF), 음식부산물 건조분말 혼합유기질비료 처리구(DFPMOF)이며 DFPMOF 처리구는 100, 200, 400 및 600%로 구분하여 설정하였다. DFP, MOF 및 DFPMOF 처리구는 질소비료 사용량을 기준으로 하여 비료처리를 하여 작물 재배실험을 진행하였다. 음식부산물의 화학적 특성은 시기별에 따라서 유의적인 차이가 없었으며 중금속 함량 또한 기준에 적합한 수준이었다. 배추 생산량은 DFPMOF 처리구가 6,280 kg 10a-1로 NPK처리구(7,000 g kg-1)와 가장 유사하였으며 질소이용효율 또한 유사한 경향이었다. 토양 pH는 DFPMOF 사용량이 증가함에 따라 감소하는 경향이었으며, EC, OM 및 Ex. K는 DFPMOF 사용량이 증가함에 따라 감소하는 경향이었다. 이를 통해 DFPMOF 는 질소비료사용량 기준으로 처리하였을 때 가장 적합할것으로 판단되나, 적정사용기준을 설정하기 위해서는 장기간 연용시험을 통한 환경영향평가가 필요할 것으로 사료된다.

This study was conducted to understand the type of use and satisfaction of delivery food by Chinese and Korean students. In December 2019, Korean and Chinese students living in Gyeonggi Province were analyzed using SPSS. The average number of food deliveries was 1~2 times a month and used 30.7% of the Korean students and 21.8% of the Chinese students. As for how to order food for delivery, 62.2% of Korean college students took up mobile apps, and 49.0% of Chinese students took up mobile phones. In terms of satisfaction after using delivery food, Korean students scored 3.89 points for taste and 3.74 points for using a neat and convenient packaging container, while Chinese students showed the highest score of 3.69 points for past eating experiences and 3.65 points for taste. As for the factors influencing the satisfaction after using the delivered food, the food quality satisfaction (β=0.518) for Korean students and favorable menu factor (β=0.533) for Chinese students were found. Therefore, it is judged that it is necessary to continuously improve the quality, service, convenience and diversity of delivered food, and health and safety factors in order to improve the delivery patterns and satisfaction of college students.

Korean Chinese international trade correspondence belongs to the teaching field of "Special purpose language". It takes various communicative contexts as the premise, and the communicative context is based on the communicative process under the specific working environment of language users. Therefore, it needs appropriate communicative functions to achieve the communicative purpose. In order to achieve the communicative function, the use of specific sentence types obviously contains some convention. The characteristics of high-frequency sentence types in international trade letters have a certain tendency. This paper takes the Chinese E-mail actually generated by the Korean staff of a Korean trading company in their trade with China as the research object, investigates and analyzes its sentence function, and provides empirical data for business Chinese teaching. Compared with the teaching of traditional lingua franca, according to the various social attributes of Korean Chinese international trade exchanges, it is not only the cognitive background of learners and staff, but also the communicative context required by professional work. The core content of teaching should give priority to the specific sentence patterns of communicative function words closely related to work in the actual corpus, and apply them in teaching strategies and methods, To enable learners to acquire the required language communicative competence as soon as possible, it does not emphasize the comprehensive mastery of learning, but can save time and selectively improve communication efficiency.

This study was performed to provide fundamental data on the convenience foods purchase according to the food-related lifestyle. This study was conducted on 398 Chinese international students residing in Gyeonggi area between October and December 2019. Among the total 373 survey subjects, gender was 183 male students (49.1%) and 190 female students (50.9%). This study was conducted by questionnaire method with reference to previous studies. There are significant differences in economic pursuit and taste pursuit for delivery food use, economic pursuit and taste pursuit for delivery food information, health pursuit and taste pursuit in delivery food ordering method, and economic pursuit and convenience pursuit for delivery food use (p<0.05). Delivery food usage time was significantly different in convenience pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05), and the delivery food preference menu was significantly different in economic pursuit, health pursuit, eating out pursuit, and taste pursuit (p<0.05). The menu positive factors among satisfaction factors showed statistically significant differences in economic pursuit (β=0.188, t=3.531) and health pursuit (β=0.160, t=3.099) among food related lifestyle factors. In conclusion, this study presented the desirable direction of delivery food usage in Chinese students.

This study conducted qualitative research through in-depth interviews on the diffusion process of Korean food in accordance with the length of residence of Chinese students in Korea. As the analysis method, the qualitative analysis method such as NVivo12.0 was used, and the analysis was performed through word frequency, word cloud, and coding matrix. The images of taste of Korean food were revealed as ‘Spicy’, ‘Sweet’, and ‘Light taste’ by both short-term Chinese residents and long-term Chinese residents. The long-term Chinese residents showed their dissatisfaction with the institutional food, and they also pointed out the importance of the matter of cooking for quick adaptation to life in Korea. The long-term Chinese residents also thought of Korean food as ‘High-fiber food’, and this was influenced by the ‘Less-oil’ cooking method of Korean food, which is different from the cooking method of Chinese food. The length of residence was used as a main variable of this study, and it was one of the factors having positive effects on the diffusion of Korean food and acculturation. It would be difficult to generalize the results because this study used the convenience sampling method and snowball sampling.

In conclusion, I would like to provide the basic data necessary for the right choice of Chinese students' dietary habits and food purchases.

Foods play important roles in Chinese gift giving behavior; they contain abundant symbolic and semiotics meanings. Typical food products are exchange during festivals, commercial intercourse, and other social intercourse occasion. The purpose of study is to investigate how the meanings and values of food gifts affect gift-giving behavior under Chinese cultural context. Qualitative in-depth interviews are applied, eighteen participants from food gift industry, academic field and consumers are invited in the study, and qualitative data analysis framework is designed based on Sheth’s consumption values theory. We find that food gifts cover function value, emotional value, social value, epistemic value and conditional value. Gift values are explained by givers and recipients during gift-giving process. Gift-giving occasion, gift-giving purpose, relationship between givers and recipients are influence the value of gift. Study provides some practical recommendation for food products design and marketing.

Diffusion of innovation theories have been used to explain the adaptation process of Chinese college students to Korean food. This study examined and compared Korean food adaptation among Chinese college students in Gyeonggido and Daejeon. A total of 141 Chinese college students were surveyed from August 01 to November supported by the Chinese Students Association in Gyeonggido. The results show that the adaptation process of Chinese college students to Korean food was different between Gyeonggido and Daejeon. Chinese college students did not have many opportunities to learn about Korean food and search information about Korean food. The adaptation process of Chinese college students to Korean food was different by residential type and period. The adaptation process of Chinese college students in Gyeonggido to Korean food was composed of three factors: interest-reinvention-adoption, awareness, and evaluation-trial-adoption. Three factors of the adaptation process of Chinese college students in Daejeon to Korean food were awareness-evaluationtrial, adoption-reinvention-trial, and interest.

This study was performed to provide fundamental data on the convenience foods purchase according to the food-related lifestyle. The subject was 250 Chinese students in South Korea region through a self-administered questionnaire. A factor analysis extracted five comprising food-related lifestyle, which we named health seeking (factor 1), taste seeking (factor 2), easy seeking (factor 3), popularity seeking (factor 4) and safety seeking (factor 5). According to the results of the reliability analysis, the food-related lifestyle showed an average of 3.16 and 0.813 for Cronbach's alpha coefficient. There were significant differences for the selection of convenience foods according to health seeking (p<0.05). Also, the popularity seeking and easy seeking lifestyle factors showed significant differences for the reason the purchase criteria of convenience food (p<0.05). There was not significant differences in convenience foods of selection criteria according to health seeking, taste seeking, easy seeking, popularity seeking and safety seeking types (p<0.05). A significant positive result of the internal characteristics of convenience foods purchase (p<0.05) was shown for the health seeking and taste seeking. A significant positive result of the external characteristics of convenience food purchase (p<0.05) was shown for the health seeking, taste seeking and safety seeking. In the correlation between convenience food purchase factors, the correlation coefficient of nutrition and ingredients are highest with 0.46, 0.445 in cooking and price, 0.441 in ingredients and expiry date, 0.383 in brand and price, 0.361 in taste and easy. In conclusion, this study presented the desirable direction of convenience food consumption in Chinese students.

In this study, we analyzed the dietary style of Chinese singles; in addition, the effect of convenience food consumption on the quality of life of singles was evaluated through construct model development on the relationship between the frequency of consumption and satisfaction with convenience food and quality of life. A statistical analysis of 153 surveys from Tianj was conducted using SPSS 12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of the data was confirmed by an exploratory factor analysis and Cronbach's alpha coefficient. The measurement model was confirmed as appropriate by a confirmatory factor analysis of the measurement model in conjunction with AMOS. The results of a factor analysis were as follows. Dietary style was categorized into four factors. The level of satisfaction with convenience food was categorized into seven factors and quality of life was categorized into four factors. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. For the level of satisfaction with convenience food based on dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. The results of all tests indicated that the model satisfied the recommended level of goodness of fit index and thus, the overall research model was appropriate. The current study highlights the increased interest in eating habits of singles and is necessary for further improvement in nutrition education.

The purpose of this study was to survey the perception and preference for Korean food among Chinese students residing in Korea (Chinese foreign students, N=69) and China (Chinese-locals, N=98). A total of 76.8% of Chinese foreign students and 70.4% of Chinese-locals had ever eaten Korean food in China before visiting Korea, and motivation to try Korean food at first was ‘easy access to Korean food restaurants’ (Chinese foreign students 38.6%, Chinese-locals 44.9%). The most important factors in selecting Korean food were ‘taste’ and ‘price’ (Chinese foreign students 72.7% and 18.2%, Chineselocals 59.1% and 22.7%, respectively), and needed improvements for Korean food were ‘spicy and salty taste’ and ‘nutritional aspect’ (Chinese foreign students 54.5% and 25.8%, Chinese-locals 33.3% and 36.4%, p<0.05). The scores for perception of Korean food were significantly lower in Chinese-locals (2.99) than in Chinese foreign students (3.31)(p<0.001). Chinese foreign students preferred Bulgogi (20.5%), Neobiani (20.1%), and Galbijjim (17.9%), whereas Chinese-locals preferred Bulgogi (16.1%), Gimbap (16.1%), and Samgyetang (15.2%) (p<0.001). The most preferred condiment was ‘Garlic’ (18.0%) in Chinese foreign students, and ‘Red pepper powder’ (16.4%) in Chinese-locals. The results of the study can be used as a foundation to prepare a globalization strategy for Korean Food.
