Wildfires, which occur sporadically and irregularly worldwide, are distinct natural disturbances in combustible vegetation areas, important parts of the global carbon cycle, and natural disasters that cause severe public emergencies. While many previous studies have investigated the variability and changes in wildfires globally based on fire emissions, burned areas, and fire weather indices, studies on East Asia are still limited. Here, we explore the characteristics of variability and changes in wildfire danger over East Asia by analyzing the fire weather index for the 40 years-1981-2020. The first empirical orthogonal function (EOF) mode of fire weather index variability represents an increasing trend in wildfire danger over most parts of East Asia over the last 40 years, accounting for 29% of the total variance. The major contributor is an increase in the surface temperature in East Asia associated with global warming and multidecadal ocean variations. The effect of temperature was slightly offset by the increase in soil moisture. The second EOF mode exhibits considerable interannual variability associated with the El Nino-Southern Oscillation, accounting for 17% of the total variance. The increase (decrease) in precipitation in East Asia during El Nino (La Nina) increases (decreases) soil moisture, which in turn reduces (increases) wildfire danger. This dominant soil moisture effect was slightly offset by the temperature increase (decrease) during El Nino (La Nina). Improving the understanding of variability and changes in wildfire danger will have important implications for reducing social, economic, and ecological losses associated with wildfire occurrences.

북한의 대량파괴무기 개발은 미국과 일본으로 하여금 TMD 계획을 추진하게 함으로써 미-중, 일-중 및 미-러간의 대결을 조장하여 동아시아지역의 안정을 해치고 있다. 특히 일본은 2002년경까지 감시위성 4기 발사 및 미국과 TMD체계 공동연구계획을 발표함으로써 동북아에서 군비경쟁이 실감나게 재현되고 있는 것이다. 일본의 TMD 체계 및 첩보위성 무장과 자위대 역할 확대가 현실화되면 동북아지역에서 새로운 첨단 군비경쟁을 촉발할 가능성은 얼마든지 있다.

인삼은 중국에서 두 가지로 분류하는데, 그 하나는 상당인삼이고, 다른 하나는 요동성인삼이다. 인삼은 대보원기작용으로 건강한 삶을 제공한다. 인삼은 오랜 역사를 가지고 있으며 질병을 치료하고 양생하는데 사용하여 왔다. 중국 전통풍습에 의하면 대한이 몸을 보하기 가장 좋은 절기인데 인삼을 주로 사용하였으며, 북방지역뿐 아니라 남방지역에도 많이 사용하여 왔다. 인삼제품복용방법은 여러 가지가 있는데, 인삼주, 인삼탕 외에 특색 있는 인삼요리 등 여러 가지 방식으로 중국음식문화와 함께 계승되어 왔으며, 이것은 중국인의 지혜를 나타내는 것이다.

The fisheries in East Asia are reviewed in conjunction with climate change and social-economic developments in the 20th century. About one third of the human population resides in this region, producing a large share of the world's fisheries products, consuming them, and contributing significantly to the international trade of the products. Ongoing local and global climate changes, as well as ocean warming and acidification, are anticipated to have significant impacts on fisheries. Frequent typhoons have brought untold calamities and miseries to coastal communities. The rate of environmental change is outpacing our ability to respond effectively. The science must now move beyond identifying issues and toward providing sound bases for the development of innovative solutions, including effective adaptation and mitigation strategies. Fisheries management plans must be made to consider both changes in climate and social systems. It seems logical that an international forum should be made available to coordinate scientific research, management, and conservation of the region's fishery resources.

The purpose of this study is to suggest the contents for geography education about East Asian cultural diversity. I chose "Human Relationship and Living-Habit" culture among East Asian diverse cultures and fixed 4 themes: family cultures, traditional cultures, friendship cultures and relationship cultures with other people. For making the lesson contents for East Asian cultural diversity, I analysed Geography 2009 Revised Curriculum and presented specific contents differently depending on grades. Until now, static and homogeneous cultures in East Asia have been emphasized mostly at school but cultures that are dynamic and related to students$^{\circ}{\phi}$ life are proposed in this study. Through understanding the differences of the East Asian cultures, it will be possible to expand mutual understandings among the East Asian people. This study will be a good alternative and paving the way for enhancing cooperations in East Asia.

This study analyzed library awareness and anxiety among people in their 20s living in East Asia. The objective is to develop the international library cooperation agenda for life-long education proliferation. User groups in Korea, China, and Japan were investigated to understand the differences in library awareness based on the situational contexts such as preferred resources, use frequency, educational level, and gender. Results of the data analysis showed the correlation between library anxiety and use patterns such as preferred information sources and frequency of use. Specifically, the user group in China has the highest level of library anxiety with every factor. Also, the Korean user group was measured to have the lowest level of library anxiety in terms of digital information factor. Based on these results, the study presents several recommendations for resolving library anxiety such as embracing new information need with regard to environmental change and suggesting a new space policy for libraries.

EAREF(East-Asia Reference Frame) is based on the Eurasian Plate which is considered relatively stable. It is managing the coordinate reference system by a specific epoch through the networking of GNSS CORS of the East-Asia region covering North-east and South-east Asia. Also it'll be the goal to assist integrating the geospatial information management. This study aims to estimate the precise coordinates of EAREF in the East-Asia region at the epoch of January 1st of 2012 (2012.0) after the Great East Japan Earthquake. It is related to 1st stage study for construction of data sets and made up the data processing techniques through the various experiments to upgrade the accuracy. Based on the results of the study, we calculated the initial precise coordinates of the EAREF network from the 2012.0 epoch covering the East-Asia region. The accuracy of the estimated coordinates was compared with the weekly solution provided by the IGS analysis centre. The differences were 0.004m, 0.007m and 0.009m at the directions of X, Y and Z respectively. In addition, this study reviews the next procedure how to implement and upgrade the EAREF network.

Wetlands are constantly affected by internal and external environments that make up the wetlands, and these effects make wetlands change. East Asia countries where about 15% of Ramsar's registered wetlands are located, is valuable conservation area due to various wetland types and biodiversity. However, due to climate change and other factors, the total area of wetlands has been reduced and biodiversity have been damaged. To mitigate these problems and to manage wetlands efficiently, it is important to identify the factors that change wetlands and to identify how each factor affects them. In this study, we conducted a wetland-related literature analysis in East Asia to derive factors that affect the changes in wetlands, and analyzed the relationships among the factors. Finally we presented research directions considering wetland change factors. In most of the East Asia countries, it was found that there is deficiency in research studies about extraction in direct factors and water-energy infrastructure, tourism & recreation in indirect factors. Also, we presented the necessity for future research using the result between connectivity & relationship analysis and indirect drivers of change and their influence on direct drivers of change. The results of this study could contribute to the establishment of an R&D cooperation system in East Asia region and strengthen wetland management.

세계의 민족에게는 그 나름대로의 식문화가 있다. 무엇을 취하여 어떻게 조리하여 어떻게 먹고 있는가가 세계 각지에 따라 다른 점이 많다. 한국 ${\cdot}$ 중국 ${\cdot}$ 일본의 동아시아 삼국에도 비슷하면서도 서로 다른 식문화가 자리 잡고 있다. 식문화의 본질은 사람들의 정신에 잠재해 있는 음식이나 식사에 대한 태도를 결정하고 있는 즉, 사람들의 음식에 대한 관념이나 가치체계라고 할 수 있을 것이다. 먹는다는 것에 관한 ‘물질’이나 ‘기술’이나 ‘인체의 메커니즘’을 소위 말하는 하드웨어라고 한다면, 그것은 소프트웨어에 해당하는 것이다. 그러나 이러한 관념이나 가치체계는 인간이 처해 있는 환경 즉, 생태학적 환경으로부터 많은 영향을 받을 수밖에 없다. 즉, 전통적인 식문화라는 것은 각 지역의 생태학적 환경에 어떻게 지배되어 왔는가라는 것을 간과해서는 논할 수 없다는 것이다. 여기에서는 수많은 음식 중에 주로 육류에 관한 한 ${\cdot}$ 중 ${\cdot}$ 일 동아시아 삼국의 식문화에 대하여 기술하기로 한다.
