Assuming the united Korea, total population is estimated to be 70 million and grain demand for the people is estimated to reach 30 million metric tons. Cultivated land in North Korea is about the same as South Korea i.e. 2 million hectares. However grain production in North Korea is about one half of South Korea's, 6 million metric tons in the South and 3 million metric tons in the North a year. This implies that the United Korea need to import more than 20 million metric tons of grain a year and it will trigger many economic and social problems for the United Korea. In order to meet deficient grain supply, the United Korea can choose three possible policy options; importation of grains or increased investment in foreign agricultural development or increase in domestic supply Among the possible policy options, increase in domestic supply is desirable and can be achieved by developing North Korea's grain supply potential. North Korean agricultural development can also be achieved most effectively through cooperation between the South and North. An effective policy option for agricultural cooperation between the South and North is supply of agricultural inputs such as fertilizer and pesticides and exchanges of agricultural technology. Cooperation between the South and North in the agricultural sector should be achieved and developed further to solve the potential food problem before unification.

Norovirus is a major cause of viral gastroenteritis and a common cause of foodborne and waterborne outbreaks. Norovirus outbreaks are responsible for economic losses, most notably to the public health and food industry field. Norovirus has characteristics such as low infectious dose, prolonged shedding period, strong stability, great diversity, and frequent genome mutations. Besides these characteristics, they are known for rapid and extensive spread in closed settings such as hospitals, hotels, and schools. Norovirus is well known as a major agent of food-poisoning in diverse settings in South Korea. For these reasons, nationwide surveillance for norovirus is active in both clinical and environmental settings in South Korea. Recent studies have reported the emergence of variants and novel recombinants of norovirus. In this review, we summarized studies on the molecular epidemiology and nationwide surveillance of norovirus in South Korea. This review will provide information for vaccine development and prediction of new emerging variants of norovirus in South Korea.

BACKGROUND/OBJECTIVES: International students face dissimilar food environments, which could lead to changes in dietary behaviors and anthropometric characteristics between before and after migration. We sought to examine the risk factors, including dietary behaviors, acculturation, and demographic characteristics, related to overweight subjects residing in South Korea. SUBJECTS/METHODS: We conducted a cross-sectional study, collecting data from 142 Chinese international students (63 males, 79 females) in 2013. RESULTS: The mean age of the subjects was 25.4 years, and almost half of them immigrated to South Korea to earn a master's degree or doctoral degree (n = 70, 49.3%). Chinese international students showed an increase in skipping meals and eating speed, but a decrease in the frequency of fruit and vegetable consumption in South Korea compared to when they lived in China. We found a statistically significant increase in weight (69.4 ${\rightarrow}$ 73.9 kg) and BMI (22.4 ${\rightarrow}$ $23.8kg/m^2$) for male subjects (P < 0.001) but no change for female subjects. We also found that overweight subjects were more likely to be highly acculturated and male compared with normal-weight subjects. CONCLUSION: Among Chinese international students living in South Korea, male and more highly acculturated subjects are more vulnerable to weight gain. This study provides useful information to design tailored nutrition intervention programs for Chinese international students.

Competition in supply chain has moved from between being organizations to between supply chain. To enhance competitiveness in supply chain, there is a need for organisations to establish and manage collaborative relationships among supply chain partners and share operational and strategic information timely and accurately. As a result, food supply chain partners have adopted of inter organisational information systems (IOIS) such as EDI, IEDI, RFID, internet, and extranets to facilitate exchange of information, streamline production and to effectively manage inventory processes so as to deliver value to the customer. Together with IOIS, cybermediaries also plays a key role in facilitating agriculture and food supply chain. This paper investigates the role and significance of IOIS and cybermediaries in facilitating agriculture and food supply chain. Convergent interviewing was conducted with agriculture producers, food processors and retailers. The study identified logistics, supply chain and customer services benefits perceived from implementing IOIS and utilising cybermediaries services in the food supply chain. To conclude the conceptual paper outlined managerial implications and areas for future research.

The Food Problem of North Korea is well known to all of us. And we, South-Koreans, are oblidged to solve the food problem of North Korea because we should prepare and cope with the reunification of Korean Penninsula in the near future. Although many organizations of the UN (including Korea) are engaged in food-support to North Korea from the humanitarian viewpoint, a great many people are disclosed to the starvation for the food deficiency. Now how to solve the food problem of North Korea? It is the agro-cooperation between South and North Korea. The most realistic method among them is the agro-cultivation in contract.

Trends of food and energy consumptions in South Korea, North Korea, and the Korean Peninsula were shown and consumptions of food and energy for the integrated Korean Peninsula with several Cases were predicted, and the directions for the environmental resources management were suggested in this study. The Food Supply Quantity, the Protein Supply Quantity, and the Food Supply of North Korea were less than those of South Korea, the Eastern Asia, and World after 1990s. However, it is expected that the food consumption in North Korea will increase, if two Koreas are integrated. If the Food Supply Quantity of North Korea is the same as that of South Korea with the maximum projected population of integrated two Koreas by 2055, the food consumption in the Korean Peninsula would increase by 25% compared with the 2011 food consumption of integrated two Koreas. Thus, the choice of diet should be carefully considered and the increase of agricultural productivity is required. Energy consumption in North Korea is very small comparing to that of South Korea and fraction of coal in energy usage of North Korea is very high. If the energy consumption per capita of North Korea after integration be the same as that of South Korea in 2011, the energy consumption in the Korean Peninsula would increase by 45% compared with the 2011 energy consumption of integrated two Koreas. To minimize the environmental effects caused by energy consumption, the energy plan with the reduced fraction of coal in energy supply of North Korea should be adopted and advanced technology with higher efficiency should be applied to establish or expand the energy facility in North Korea.

Lactic acid bacteria (LAB) have caused many microbiological incidents in the brewing industry, resulting in severe economic loss. Meanwhile, traditional culturing method for detecting LAB are time-consuming for brewers. The present review introduces LAB as spoilage microbes in daily life, with focus on LAB in the brewing industry, targeting at the spoilage mechanism of LAB in brewing industry including the special metabolisms, the exist of the viable but nonculturable (VBNC) state and the hop resistance. At the same time, this review compares the traditional and novel rapid detection methods for these microorganisms which may provide innovative control and detection strategies for preventing alcoholic beverage spoilage, such as improvement of microbiological quality control using advanced culture media or different isothermal amplification methods.

Agricultural systems in South Asian countries are dominated by smallholder farmers. Additionally, these farmers have limited access to pre- and post-harvest technologies due to their high initial cost. The lack of these technologies in postharvest handling is responsible for 20% to 44% of fruit and vegetable losses. These high losses are largely the result of a generally weak basic postharvest infrastructure for the preservation of products, which avoids damage from improper handling, transportation, packaging, and storage. High postharvest losses of products negatively affect food availability, food security, and nutrition, as the producer is able to sell less of the farm yield and the net availability of these food commodities for consumption is reduced. An underlying cause of these postharvest losses is the limited awareness and knowledge bases of stakeholders (researchers, farmers, governments, non-governmental organizations, and merchants) in the traditional supply chains in which these losses occur. The analysis presented in this paper explores the state of postharvest practice in South Asian countries and discusses options for low-cost postharvest technologies in the region that can support small-scale farmers and provide a viable pathway for supply to the market, joining with modern value chains and bringing about individual and regional reduction in postharvest losses of fruits and vegetables. The improvement of basic and simple low-cost technologies through precise research efforts has the potential to prevent such huge losses of products, and help meet the ever-increasing demand for food in South Asian countries.

This study analyzed the Food Neophobia Scale (FNS) and Korean food perception status of Southeast Asian workers living in South Korea in order to build up basic data to develop a desirable diet program. From our study, we found that FNS was higher in the order of Cambodian, Myanmar, Vietnamese, and Thai workers. Influential demographic factors for FNS were cooking possibility and place of residence. The mean scores of Cambodian workers ($3.46{\pm}0.63$) regarding "positive perception of cooking method, taste & color" about Korean food were the highest among the four countries, followed by Vietnam ($3.38{\pm}0.68$), Myanmar ($3.26{\pm}0.50$), Thailand ($3.09{\pm}0.64$)workers(p<0.01). The mean scores of Myanmar workers regarding perception of "difference in cooking method, smell & texture" and "difference in taste" were the highest among the four countries. FNS had a negative correlation with the factor "positive perception of cooking method, taste & color" regarding Korean food and a positive correlation with the factors "difference in cooking method, smell & texture".
