This paper is concerned with the positive steady states of a diffusive Holling type II predator-prey system, in which two predators and one prey are involved. Under homogeneous Neumann boundary conditions, the local and global asymptotic stability of the spatially homogeneous positive steady state are discussed. Moreover, the large diffusion of predator is considered by proving the nonexistence of non-constant positive steady states, which gives some descriptions of the effect of diffusion on the pattern formation.

Global warming caused by greenhouse gases is threatening our ecosystem. Moreover, our food system is in severe danger. Recently the local food system is emerging as an alternative food network, decreasing food miles and carbon dioxide emissions, protecting the safety of our foods, and helping local economy. However, carbon labelling for agricultural products has not been introduced yet in Korea. Accordingly, research on food miles and carbon labelling for agricultural products should be urgently conducted. The study compared the food miles and the carbon dioxide emission of major agricultural products. In addition, the food mileages of garlic and carrot are compared between Korea and China. The results show that radish has the highest carbon dioxide emission, and followed by onion and cabbage. These products are produced from Jeju island and have a high Shipment volume. Although Chinese Garlic and radish have lower shipping volume and food miles than Koreans, they have higher carbon dioxide emissions due to ship transportation. Based on these results some valuable implications can be identified. Current food distribution system, which heavily focuses on the Metropolitan area, should be changed into a local system, in which foods are consumed in the local area first then transported to other area.

This study aims to establish the indicator system of the quality of life of rural residents and to estimate the weights among criteria or sub-criteria that constitute the indicator system of the quality of life using AHP(Analytic Hierarchy Process) method. Indicator system consists of four criteria, that is, health care, eduction & culture, living environment, and income and jobs. Each criterion include three sub-criteria that make up corresponding criterion. The results show that income and jobs was most highly evaluated among the four criteria. It was followed by health care, living environment, and eduction & culture. Among the total 12 sub-criteria, annual income was most highly evaluated, followed by medical service level, job satisfaction, and public transportation environment in terms of global weight which was deduced from expert questionnaire survey. This study implies that rural development policy needs to focus on increasing rural residents' income by creating good quality occupations and increasing the level of medical services, and expanding public transportation services in rural areas. This study has failed to collect local residents' opinions regarding their quality of life in spite of the efforts to reflect the opinions from various expert groups, which is the limitation of this study.

The obese population has been increasing worldwide and obesity has become one of the socioeconomic problems. Obesity raises more concerns as more studies regarding its direct and indirect relativity to several diseases such as type II diabetes, hypertension, etc. are published. Since leptin, an important signal in the chronic control of food intake and energy expenditure, was discovered in 1994, there has been a great accumulation of knowledge on fighting obesity by facilitating pharmacological and nutritional strategies on the molecular level of the body weight control system. In particular, evidences are accumulating that particular food components affect our physiological function and gene expressions which are associated with body weight control. In this study, we review the four mechanisms for weight control and antiobesity functional agents such as HCA, L-carnitine, CLA, chitosan, calcium supplements capsaicin contained in red pepper, and oriental herbal mixture. We also describe about the efficacy and working mechanism of these functional agents on the basis of antiobesity mechanisms.

Sustainable and healthy diet is a challenge in recent world. Despite the global depletion of water resources, Korea has no system for controlling its water footprint. This study established the water footprint tables of Korean food using the Water Footprint Network databases, and applied them into two meal plans for 19~64 year-old adults recommended in the Dietary Reference Intakes for Koreans 2020. Nut, oil, and meat's water footprints were higher and those of fruit and vegetable were lower. Sesame oil had the highest water footprint of 21,793 L/kg and pineapple had the lowest domestic water footprint of 102 L/kg. Water footprint of one serving size of beef was 925 L, that of chicken was 260 L, and those of soybean were 43 L in global and 81 L in domestic. The water footprint of the recommended 2,400 kcal meal plan was 2,882 L, and that of 1,900 kcal meal plan was 1,915 L. The water resources can be saved by choosing food with lower water footprint. The results of this study can be used in the further researches for more sustainable and healthier Korean diet.

This essay investigates how the industrialization of the US food system was closely linked to US foreign policy, gender issues, and the rise of consumerism in the Cold War era. While many scholars in American studies and women's studies over the past few decades have paid increasing attention to the interrelationship of gender politics and the media industry in shaping US domesticity, they have seldom studied how and why reading gender issues in relation to environmental discourse in general and the industrialized US food system in particular can help us better understand the complex relationship between environmental and social problems that we are facing today, both collectively and individually. In this context, this essay shows how US national politics have not only created the ideal of American domesticity that promotes traditional gender roles and consumerism at the expense of gender equality, but also negatively affected women's somatic and mental health writ large. By closely examining the cultural implications of Nixon's and Khrushchev's Kitchen Debate in the 1950s alongside newspapers, photographs, advertisements, and Sylvia Plath's The Bell Jar (1963), I argue that reading Cold War consumer culture in relation to the US food system leads readers to see the invisible links between gender politics and today's environmental and social problems in comparative and global contexts.

The food R&D operating system needs to be changed according to the changes in the food industry as well as the domestic and overseas environments. In this aspect, a future-oriented food R&D operating strategy linked with the governmental policy are proposed to foster the promising food industry. The strategic R&D approaches are summarized on the basis of global mega-trends and food industry trend analysis, and current R&D status and issues are also reviewed to set the R&D operating direction for future food industry. To advance the R&D operating system of the food industry, some practical suggestions are given as follows: strengthening the research planning system for efficient R&D program operation, enhancing the role assignment and collaboration among the R&D organizations, reinforcing the support system tailored to industrial sites and securing the future technology bases as well as resolving present issues, and linking R&D programs with policies and improving the food R&D management system.

Prolonged Russia-Ukraine war, and unstable situation of supply and demand of global crops including the COVID-19 pandemic have raised awareness regarding food crisis, and in addition to this situation, export restriction measures imposed by some countries have accelerated the rise in the prices. Since the Republic of Korea depends annual crop consumption (21.32 million tons) mostly on the imports (food self-sufficiency rate in 2020 was 45.8%, crop self-sufficiency rate was 20.2%), our main task is to stably secure food. Now we need to put focus on building capacity to secure stable food supply, and actively manage and respond to risks. To overcome this condition, the Korean government set robust food sovereignty as its policy task, and has been focusing on the policy capacity by providing financial and policy support in parallel. We need to implement mid- to long-term measures to strengthen food security as well as to ensure domestic price stability. While increasing the domestic capacity to supply food in the mid- to long-term perspective, we are implementing projects to bring in crops which are inevitable to be imported by private companies. Specifically, we are making efforts to expand infrastructure for the public reserve and domestic production of wheat and beans which have low self-sufficiency rate, and to secure food sovereignty by providing support to secure global crop supply chain to private companies. The Ministry of Agriculture, Food and Rural Affairs plans to set a target for food self-sufficiency rate and prepare a policy to strengthen mid- to long-term food security by establishing a task force to strengthen mid- to long-term food security in the Ministry. Especially, although wheat is the second staple food, domestic wheat production and the foundation for the industry is poor. Compared to the wheat imports, domestic production of wheat is 30 thousand tons (self-sufficiency rate of 1%), leading to a vulnerable status against internal and external shocks. Through the establishment of the Wheat Industry Promotion Act (Feb. 2020) and the First Master Plan for Wheat Industry Promotion (Nov. 2020), the Korean government has developed a policy basis, and has been providing financial support in overall across the production, distribution and consumption process. In addition, the government established a production complex for Korean wheat and beans in order to supply affordable government-supplied commodities, provide education and consulting services, and create a high-quality stable production system, including facilities and equipment. We are also continuing to increase the public reserve for wheat and beans with the purpose of stable supply and demand as well as food security. The Korean government will establish and implement mid- to long-term measures to strengthen the foundation for domestic production across production, distribution and consumption process, and to stably secure global supply chain including through diversified import channels.

The paper examines dynamic relationship among 'Limit to Growth' factors in Korea using causal loop diagram. It also aims to explore policy implications for Korea in overcoming current difficulties and future crisis we may face. For this purpose, five factors -economy, population, resource, environment, food- used in the were adopted as an analytical framework. Findings show that Korea is fragile to external shock such as world economic crisis, food price surge, and resource price -including energy price- hike. High dependency of energy, food and resource on foreign market was found to be a major source of limit to growth in Korea. Furthermore, environmental problems like global warming could be a major external shock that could hit Korea harder than the rest of the world. Policy implications and measures for these problems were discussed too.
