Microhabitat segregation among grasshopper species in Asia has not been well studied. We determined the differences in the use of substrates by three common North East Asian grasshopper species co-existing on a natural meadow near Seoul, South Korea. While many Oedaleusinfernalis individuals were found on the ground, Acridacinerea and Atractomorphalata were usually observed on plants. Acridacinerea was mostly observed on the grass Zoysiajaponica (Poaceae) and Atractomorphalata was mostly found on plants from the family Asteraceae. This is the first study to provide quantitative information about microhabitat differences among some common grasshoppers in rural habitats of continental North East Asia. Future studies should focus on determining the mechanisms that produce such ecological segregation.

In 1972, the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention) was negotiated. It is a global treaty, for the first time, to regulate dumping of waste at sea worldwide. Following this global endeavor, the Protocol to the London Convention (London Protocol) was later agreed to further modernize the London Convention so as to reinforce the management of dumping of waste at sea. While in East Asia, only China, Japan, the Republic of Korea (South Korea) and the Philippines have acceded to the Convention and its Protocol, other countries do not show their willingness to sign them. Against this background, this article will address the responses of these East Asian states to the implementation of the London Convention, and analyze and assess their relevant laws and regulations with particular reference to China’s practice. In addition, it will focus on new challenges, such as offshore carbon storage, to the London Convention.

The paper covers relevant issues, such as the current state of the tourism services sector in China, Japan, and South Korea. The significance is confirmed by the growing role of the North-East Asian countries in the world trade in services and the growing contribution of tourism to the global gross domestic product. The purpose of this study is to identify the features, problems, and prospects for the development of the tourism services sector in China, Japan, and South Korea. The paper uses methods of systematisation and typification, which made it possible to determine the specifics of the development of cultural tourism in the Far Eastern region among the current range of opinions and areas of cultural tourism research. The study uses the principles of historicism and objectivity, which allowed analysing the development and current state of tourist exchange. A cultural approach was also used to reconstruct the cultural and humanitarian population of North-East Asia through the mutual enrichment of nations and people. The systematic approach made it possible to understand the importance of humanitarian exchange between people and identified the universality of tourism.

Chapter 4 describes the rising phenomena of East Asian regionalism in the wake of the Asian financial crisis and demonstrates how debates between inclusive and exclusive variations of Asian regionalism played out in the development of the regional architecture. The chapter traces the establishment of the ASEAN Plus Three, the East Asia Summit, and the Six-Party Talks. Taken together, these three institutions signified greater political will behind regional multilateralism but also revealed the contentious nature of institution building. The discussion of multilateral developments is juxtaposed to an analysis of the US–South Korea and US-Thailand alliances, and their resilience in an era of greater multilateralism and expanding regionalism.

Seven species of the family Candonidae Kaufmann, 1900 are reported from South Korea. Five species are described as new, all belonging to the subfamily Candoninae Kaufmann, 1900 and the tribe Candonini Kaufmann, 1900: Candona quasiakaina sp. nov., C. sillae sp. nov., Fabaeformiscandona koreana sp. nov., Typhlocypris choi sp. nov., and Schellencandona tea sp. nov. A very close resemblance between Candona sillae and the European C. improvisa Ostermeyer, 1937 prompted a redescription of the latter species based on the type material, and designation of the lectotype. One species of the tribe Candonopsini, Candonopsis transgrediens Brehm, 1923, previously known only from China, is reported from Korean freshwater habitats, and its first redescription is provided, along with a key to the world representatives of the genus Candonopsis Vávra, 1820. One species of the subfamily Paracypridinae, Dolerocypria mukaishimensis Okubo, 1980, previously known only from Japan, is redescribed from Korean brackish water habitats, and some notes on its variability are provided. A checklist of the Candonidae ostracods from East Asia is also provided, but only for those species that have been well-documented and taxonomically described.


Significance Inbound and outbound Asian tourism has exploded over the last 20 years, especially in East and South East Asia. However, the sector faces challenges. Impacts Supporting tourism, Asia hosts three Olympics in a row -- South Korea 2018 (winter games), Tokyo 2020 (summer) and Beijing 2022 (winter). Tourism is a key source of exports and dollars; if Cambodia is hit by sanctions after its disputed election, tourism could cushion GDP. In ten years the UN sees India's population overtaking China's, making Indian travellers key to East and South-east Asian tourism.

Contemporary industrial hubs evolved in East Asia after the 1950s and have been associated with the industrial catch-up of the East Asian economies and their industrial policies. This chapter has three main objectives: to depict the path of hubs development in these pioneering economies and provide a synthesis of the East Asian experience; to extract relevant lessons for policymakers and practitioners; and to provide a perspective on how industrial hubs can synergize industrialization and technological catch-up. Although there are commonalities, experiences have been uneven across these economies with different stages of development. The experiences of the first-generation industrial hubs, namely, Taiwan (China), South Korea, and Singapore are reviewed, followed by China as the second generation. A synthesis, key observations, and conclusions are reviewed. The chapter will complement the other chapters under Part IV through synthesis and lessons, while it complements the analytical perspectives under Parts I and II of the Handbook, by building on arguments and conceptual perspectives.

Cytherois gajinensissp. nov. is described and Violacytherois sargassicola (Hiruta, 1976) is redescribed. The species have been collected from littoral and interstitial waters in South Korea. They belong to Cytheroisinae, one of the three Paradoxostomatidae subfamilies. Both species are the first taxonomic records of the subfamily in Korea. Taxonomic keys to the living Paradoxostomatidae genera are provided in an attempt to clarify the position of some of the currently included genera as well as a key to East Asian Cytheroisinae species in order to facilitate further biodiversity research in the region.

Предпринята попытка сравнить степень внедрения цифровых решений в ключевые области жизни, такие как предпринимательство, экономика, государственное управление в России и странах Северо-Восточной Азии. Выявлены сегменты, в которых Россия сильно уступает своим восточным соседям, а также определены возможные направления цифровизации, в которых она может составить конкуренцию, а в приоритете занять ведущую роль, став своеобразным держателем стандарта и ключевым игроком по определению дальнейшей траектории развития соответствующих технологий. This paper attempts to compare the degree of the digital solutions implementation in the key areas of life, such as entrepreneurship, Economics, and public administration in Russia and in the countries of North-East Asia. The Japanese strategy «Society 5.0» is widely known in the world. In South Korea, the efforts are focused on the creative economy development. China shows a keen interest in the development of the digital economy and, moreover, claims to be the global domination and standards settler in the newly emerging areas of technological development. In Russia, at the moment, the main focus is on the development of information infrastructure and digital public administration, while the statutory regulation and personnel training are noticeably lagging behind. The segments in which Russia is significantly inferior to its Eastern neighbors have been identified, possible areas of digitalization in which it can compete, and in the priority to take a leading role, becoming a kind of standard holder and a key player in determining the future trajectory of the appropriate technologies’ development have also been identified.
