Purpose: Food security is a dynamic concept, which has continuously integrated new dimensions and levels of analysis over the years; this reflects the wider recognition of its complexities in research and public policy issues. Food insecurity is a major challenge for Ethiopia and for many African countries. This paper aims to identify the roles of social enterprises to overcome food insecurity. Research design, data and methodology: The research has focused on one primary question. What are the role of social enterprises to overcome food insecurity? The survey questionnaire was developed and an interview was made using enumerators. A total sample size of 400 sample households was selected randomly using the method of sampling with probability proportionate to size. Descriptive and inferential statistical analysis methods were used for data analysis. Results: Results of the regression analysis show that all of the hypothesized independent variables are significantly and positively affecting post membership income of the sample households. Conclusions: all stakeholders as government, development actors and academic institutions should closely monitor and support social enterprises/cooperatives technically, financially and materially. By doing so, the full potential and contributions of social enterprises in reducing unemployment and solving the social and environmental problems can be effective.

Because food crops serve as the raw materials for biodiesel, the increasing use of biodiesel as an alternative fuel can lead to adverse effects such as food price inflation and may contribute to global starvation. To solve these problems, efforts are being made to explore various nonedible raw materials for producing biodiesel. Different raw materials impart different fuel characteristics to biodiesel. In this study, we synthesized pure fatty acid methyl ester (FAME), which is a biodiesel component, and then analyzed its fuel properties. The fuel properties of pure FAME would be useful in producing biodiesel from various new raw materials.

Purpose - In Chinese rose market, Korea competes against Latin American and African countries, but is not so competitive in terms of price and quality, implying the importance of using appropriate marketing strategies. This study aims to examine Chinese rose consumers' recognition and attributes of preference for roses produced in Korea, in order to use the result as baseline data for Korean rose exporters to China and provide implications that help establish a variety of marketing strategies targeting each region, income and age group. Research Design, Data and Methodology - 112 Chinese people were involved and interviewed in Chinese horticulture industry who had participated in 2016 Hortiflorexpo IPM Beijing. Online questionnaire survey was additionally conducted with 533 Chinese living in Korea and China. The Conjoint Analysis was conducted for region, age, and income group of respondents to estimate the relative importance of rose attributes evaluated by each population group and the utility derived from each attribute level. This process aimed to compare respective population groups for the relative importance and utility to derive implications for targeted marketing strategies. Results - The analysis finds that Chinese rose consumers prioritize rose color, followed by price, flowering stage, and flower size in purchasing roses. They prefer red roses most, followed by pink and then yellow. Moreover, they prefer larger roses, and relatively cheaper roses. The analysis reveals they prefer roses in their 20%-flowering stage to more than 40%-flowering stage. Conclusions - Establishing marketing strategies differentiated for each Chinese consumer group is critical in expanding Korean rose export. The analysis finds while Chinese consumers living in Beijing considered rose color and flowering stage more importantly than their counterparts in Shanghai, Chinese consumers living in Shanghai considered rose price and size more importantly than their counterparts living in Beijing. Therefore, establishing marketing strategies based on these attributes of preference in each region is necessary. Mid & low-income consumer groups considered price as the most important factor, and high-income consumer groups considered rose color as the most important one. It is, thus, important to focus on rose color when establishing a marketing strategy with targeting the high-income consumer group.

In this study, 70 kinds of nutritional composition for five bokkeumbap products(spicy chicken, shrimp(saeu), haemul, nakji, and barbecue bokkeumbap) in high-frequency processed foods were analyzed. Raw data of intake amounts were collected from the 7th Korea National Health and Nutrition Examination Survey. Regarding proximate composition, spicy chicken bokkeumbap had lower water content and higher carbohydrate content than other bokkeumbaps, resulting in the highest total calories. The proximate composition of other bokkeumbaps were all distributed within a similar range. Vitamin content differed according to ingredients added to the bokkeumbaps. Haemul bokkeumbap had high content of vitamins B₁ and B₂, nakji bokkeumbap had high content of vitamin C and β-carotene, and barbecue bokkeumbap had high content of total niacin, folic acid, and vitamin A. For mineral content, barbecue bokkeumbap showed the highest content distribution, while nakji bokkeumbap showed the lowest content distribution. Regarding fatty acid and fat content, the highest content of fatty acids, saturated fats, and trans fats was detected in shrimp(saeu) bokkeumbap. For amino acid content, barbecue bokkeumbap showed highest content distribution. These results can be used as salient basic data for a food nutrient composition database and to significantly contribute to consumers' health.

Purpose - The Export Infrastructure Strengthening Program(EISP) is a project to expand exports of agri-food products through providing customized export information to food distribution companies and supporting overseas information activities. A total of 39.6 billion won was provided by 2016. So, the purpose of this study is to analyze whether EISP is effective for expanding exports of agri-food products. Research design, data, and methodology - A simple average difference between the export performance of the policy beneficiaries and the non-policy beneficiaries can be biased if the export capacity or inherent characteristics of the enterprise are not taken into consideration. In order to solve the problem of such a bias, the propensity score matching(PSM) method has been employed in this study. PSM is a method of converting the characteristics of an export company into an index through logit analysis and then reducing the matching to one dimension to improve the accuracy of the performance measurement. Results - The balancing test was conducted to determine how the characteristics of the policy beneficiary group and the matched policy non-beneficiary group corresponded to each other. As a result of the test, we could not reject the null hypothesis that there was no difference between the two groups, so that after the matching, the two groups were similar and the explanatory variables were well controlled. Using the nearest neighbor matching with propensity score estimating through logit analysis, we estimated average treatment effect on the treated(ATT). The food companies participating the EISP had the effect of increasing the exports of $ 5.88 million. As a result, the number of export contracts increased by 11.77, the number of exporting countries by 7.52, the number of export items by 47.51, and the number of buyers' consultation by 3.50. And overseas marketing expenses increased by 35.92 million won. Except for the number of export contracts, other export performance results showed statistically significant results. Conclusions - As the EISP has a positive effect on the expansion of agro-food exports, efforts should be made to find out the limitations or problems of the policy in the future and to make a greater contribution to the increase of exports.

Dietitians' satisfaction between elementary school and high school in KangWon Do region were surveys with questionnaires. 61 elementary school dietitians and 30 high school dietitians participated. The dietitians in elementary schools had higher scores in age, marital status, years at work, types of employment, average annual income and had lesser hours of work. In overall, elementary schools had higher percentage on self operation and on the period of their food distribution to students. High schools had higher percentage on conventional systems, freedom in the amount of food distribution, number of meals per day and the meal charge. It was clear that dietitians in high schools showed more interests in changing their careers due to the poor working environment and salary. The highest score was on the relationship with other coworkers and the lowest score was on the poor working environment and salary. In general, dietitians in both types of schools are not satisfied with their career, especially with the working environment and salary.

In this study, we developed an application that can efficiently store and manage food ingredients in refrigerators. Rather than purchasing a new smart refrigerator, a small 'pocket scanner' is inserted inside the refrigerator using an existing refrigerator to track the location of food entering and leaving the refrigerator to efficiently organize the refrigerator and save time searching for ingredients. In addition, since it can automatically record the distribution period and purchase date, it notifies users through an alarm when the distribution period expires or is shortly left. As for the research method, after discovering the needs of users through in-depth interviews, the reactions of users were investigated by adding functions that fit those needs. Users felt satisfied with managing food efficiently through the 'pocket scanner' attached to the refrigerator and answered that it was very economical because various smart functions could be used without changing to a smart refrigerator. In the next study, we will also examine the usability of the application through usability evaluation.
