Korea is undergoing a rapid environmental change in health and welfare. Therefore, the law mandates the establishment and implementation of plans in accordance with the changes. A total of 49 long-term plans related to health and welfare were specified by the National Law Information Center, the Korean representative legal information website managed by the Korea Ministry of Government Legislation. Of the 49 long-term plans, 10 plans (20.4%) were not yet fully constructed. Eight out of 10 non-constructive plans have been put into force for more than a year, but these plans still require further systematic planning and development. The complete construction of long-term plans is substantial to account for the changes in South Korean health and welfare. In addition, a systematic plan with solidarity and continuity between the mutual plans should be established in planning.

Due to the recent increase in greenhouse gases in atmosphere, world climate is rapidly changing and in turn, the earth ecosystem responds upon the climate changes. Comparing the ecosystem in the past, the present shapes of ecosystem is the result of the serious modification. Fishery resources in marine ecosystem, which usually occupy the upper trophic level, are also inevitable from such changes, because they always react to the natural environmental conditions. The northwestern Pacific is the most productive ocean in the world producing about 30% of world catch. From time to time, however, it has been notified that abundance, distribution and species composition of major fish species were altered by climate events. Furthermore, primary productivity of the ocean is not stable under the changing environments, so that carrying capacity of the ocean varies from one climate regime to another. Major climate events such as global warming, atmospheric circulation pattern, climate regime shift in the North Pacific, and El Nino event in the Pacific tropical waters were introduced in relation to fisheries aspects. The current status and future projection of fishery production was investigated, especially in the North Pacific including Korean waters. This new paradigm, ecosystem response to environmental variability, has become the main theme in marine ecology and fishery science, and the GLOBEC-type researches might provide a solution far cause-effect mechanism as well as prediction capability. Ecosystem management principles for multi-species should be adopted for better understanding and management of ecosystem.

Objectives : The aim of this study is to summarize the current conditions and implications of health inequalities in South Korea. Methods : Through a literature review of empirical studies and supplementary analysis of the data presented in the 1998, 2001, and 2005 KNHANEs, we evaluated the extent and trends of socioeconomic inequalities in both health risk factors, such as smoking, physical activity, and obesity, and outcomes, such as total mortality, subjective poor health status by self-reports and metabolic syndrome. Relative risks and odds ratios were used to measure differences across socioeconomic groups, and the relative index of inequality was used to evaluate the changes in inequalities over time. Results : We found clear inequalities to various degrees?in most health indicators. While little change was observed in mortality differences over time, the socioeconomic gaps in risk factors and morbidity have been widening, with much larger differences among the younger population. Conclusions : Socioeconomic inequalities are pervasive across various health indicators, and some of them are increasing. The trends in socioeconomic inequalities in health should be carefully monitored, and comprehensive measures to alleviate health inequalities are needed, especially for young populations.

In order to understand the economic damage of economic sanctions on trade between Korea and Russia, a trade structure analysis was conducted through statistics on import and export trade between Korea and Russia. Through the structural analysis of product trade, we tried to accurately analyze the current status of product trade between Korea and Russia. In the trade structure analysis, it was confirmed that the trade in goods between Korea and Russia decreased the most in market share and trade concentration. However, trade specialization, comparative advantage by market, and intra-industry trade index were not significantly affected despite strong economic sanctions. from Russia's point of view Smart measures are needed to address the current situation to avoid a greater economic downturn. The end of the war and the restoration of partnership with other countries are considered the most beneficial solutions for Russia and all countries, but it is difficult to predict how the war will go or what economic situation Russia will be in after the war.

Arctic warming is a global issue. The sea ice in the Arctic plays a crucial role in the climate system. We thought that a recent abnormality in many countries in the northern hemisphere could be related to the effects of shrinking sea ice in the Arctic. Many research groups monitor sea ice in the Arctic for climate research. Satellite remote sensing is an integral part of Arctic sea ice research due to the Arctic's large size, making it difficult to observe with general research equipment, and its extreme environment that is difficult for humans to access. Along with monitoring recent weather changes, Korea scientists are conducting polar remote sensing using a Korean satellite series to actively cope with environmental changes in the Arctic. The Korean satellite series is known as KOMPSAT (Korea Multi-Purpose Satellite, Korean name is Arirang) series, and it carries optical and imaging radar. Since the organization of the Satellite Remote Sensing and Cryosphere Information Center in Korea in 2016, Korean research on and monitoring of Arctic sea ice has accelerated rapidly. Moreover, a community of researchers studying Arctic sea ice by satellite remote sensing increased in Korea. In this article, we review advances in Korea's remote sensing research for the polar cryosphere over the last several years. In addition to satellite remote sensing, interdisciplinary studies are needed to resolve the current limitations on research on climate change.

In recent years, technology is rapidly changing to support new service consumption and distribution models in multimedia service systems and hybrid delivery of media services is a key factor for enabling next generation multimedia services. This phenomenon can lead to rapidly increasing network traffic and ultimately has a direct and aggravating effect on the user's quality of service (QOS). To address the issue, we propose a novel system architecture to provide smart hybrid media services efficiently. The architecture is designed to apply the software-defined networking (SDN) method, detect changes in traffic, and combine the data, including user data, service features, and computation node status, to provide a service schedule that is suitable for the current state. To this end, the proposed architecture is based on 2-level scheduling, where Level-1 scheduling is responsible for the best network path and a computation node for processing the user request, whereas Level-2 scheduling deals with individual service requests that arrived at the computation node. This paper describes the overall concept of the architecture, as well as the functions of each component. In addition, this paper describes potential scenarios that demonstrate how this architecture could provide services more efficiently than current media-service architectures.

Following the COVID-19 pandemic, many people are increasingly becoming interested in health and environmental issues. Therefore, the sale of vegan or vegetarian products has been increasing over the last few years, as well as interest in non-dairy plant-based milk that can replace cow's milk. Furthermore, the global food industry has developed an interest in such products, considering the recent changes in consumer trends. In Korea, various products are being launched annually due to the increasing interest in non-dairy plant-based milk. However, research with regard to the quality and type of products produced in Korea is still at the preliminary stage when compared to those in the United States and Europe. Therefore, the present review has summarized non-dairy plant-based milk analogues based on the following key aspects. First, the types of non-dairy plant-based milk analogues and their production technologies (in the order of almond milk > cocoa milk > coconut milk > hemp milk > kidney bean milk > oat milk > peanut milk > rice milk, and soy milk). Second, the current status and future prospects for non-dairy plant-based milk analogues. Third, recent trends and future challenges associated with the production and quality improvement of non-dairy plant-based milk analogues. Fourth, the current status and outlook of the non-dairy plant-based milk analogue market in Korea. In conclusion, the present review could provide the food industry with valuable information regarding non-dairy plant-based milk analogues to facilitate the development of related products. Data were obtained from previously published studies.

This paper proposes an approximated contact force model to identify the nonlinear behavior of a fuel rod with gap supports; also, the numerical prediction of interfacial forces in the mechanical contact of fuel rods with gap supports is studied. The Newmark integration method requires the current status of the contact force, but the contact force is not given a priori. Taylor's expansion can be used to predict the unknown contact force; therefore, it should be guaranteed that the first derivative of the contact force is continuous. This work proposes a continuous and differentiable contact force model with the ability to estimate the current state of the contact force. An approximated convex and differentiable potential function for the contact force is described, and a variational formulation is also provided. A numerical example that considers the particularly stiff supports has been studied, and a fuel rod with hardening supports was also examined for a realistic simulation. An approximated proper solution can be obtained using the results, and abrupt changes from the contacting state to non-contacting state, or vice versa, can be relieved. It can also be seen that not only the external force but also the developed contact force affects the response.
