(고도 정보통신 네트워크 사회형성 기본법(통칭 : IT 기본법))의 기본 이념과 역할에 대하여 서술함과 동시에, 이것에 기초하여 고속 접근이 가능한 인터넷망을 정비하여 세계 최첨단의 (IT 국가)를 지향하는 (e-Japan 전략)에 대하여 살펴본다. 그리고 그것을 구체화하여, 고도 정보통신 네트워크 사회형성을 위해 정부가 신속하고도 중점적으로 실시해야 하는 시책의 전모를 명확하게 밝힌 (e-Japan 중점계획)의 세부사항에 대하여 법적 관련성을 중심으로 살펴본다. 또한 IT 사회에 있어서, 글로벌 네트워크 형성 및 이것을 이용한 전자상거래 등에 관해서는 국가간의 제휴.조정이 불가결하다는 인식을 기본으로 국제적인 IT법의 환경정비에 대해서 다루기로 한다.

The paper reviews data available on euglenophycean algae of the genus Eutreptiella from the Russian waters of East/Japan Sea. Five species (such as E. braarudii, E. eupharyngea, E. gymnastica, E. cf. marina, and E. pascheri) were identified in our study. E. cf. marina and E. pascheri were found for the first time in the fare astern seas of Russia (including East/Japan Sea, Bering and Okhotsk seas). Morphological descriptions of species are based on light and electron microscopical studies and supplied with information on ecology and distribution. Original micrographs of these species obtained by light and electron microscopy are presented. It was established that E. eupharyngea, E. gymnastica, and E. pascheri cause water "blooms" in spring and summer in eutrophic coastal areas of Peter the Great Bay (East/Japan Sea), where their cell concentrations at these periods exceed $1\times10^6\;cells\;l^{-1}$.

In recent years, although far behind, the "e-Trade (B to G)" is propelled vigorously in Japan. But the diffusion of the "e-Trade" among companies (B to B) represented by bolero.net does not meet expectation. This paper carried out the questionnaire survey to the enterprises, which adopt bolero.net and examined why the diffusion is stagnated to the measures for its future spread. As a result, the top 3 adoption factors are: (1) Transaction climate, (2) Top management support, and (3) Operational improvement. In other words, it depends that top management has the will, which adopts e-trade positively among the reliable business partners and the operational performances can improve efficiently by carrying e-trade. We would like to clarify what will be crucial to spur the diffusion in the future. Based on the findings from the result, the concrete key points to promote the spread are to be indicated as follows: (1) Improve the scores of "Cost" and "Competitive pressure" (2) Improve the institutional factor.

Purpose - The purpose of the study is to propose a theoretical framework of cross-border e-commerce ecosystems based on blockchain technology. The ecosystem includes five systems, namely, crossborder supply chain intelligent system, cross-border logistics system, cross-border payment system, cross-border product quality traceability system and cross-border customs supervision system. Design/methodology - This study firstly derived the main improvement factors for the new ecosystem based on blockchain through prior research and expert interviews on cross-border e-commerce. Then explored the use of virtue of decentralization, anti-counterfeiting traceability, consensus mechanism, smart contract and other means of the core technology of blockchain to overcome the bottleneck of cross-border e-commerce development among Korea, China, and Japan. Finally, proposed valuable implications in both theoretical and practical perspectives. Findings - As a result, we combined with the problems existing in cross-border e-commerce among Korea, China and Japan, this paper proposes a solution based on blockchain. On this basis, it constructs a cross-border e-commerce ecosystem among these three countries, including five systems. In addition, we discuss the main problems existing in the current blockchain, such as low transaction concurrency, security loopholes, and inconsistent standards, the corresponding countermeasures are proposed from the technical level, security level and industry standards. Originality/value - This study is the first to apply the blockchain technology to solve the cross-border e-commerce problems in Korea, China and Japan, which is of pioneering significance in both literature and practice. Block chain technology is in the ascendency. This study provides technical solutions for promoting the development of cross-border e-commerce import and export trade between Korea, China and Japan.

E-Commerce in China is being expanded by way of policy for improving e-Commerce such as e-Government though China introduced e-Commerce later than other countries. There is going to be an e-Commerce boom in China owing to IT development and increasing use of Internet. It is estimated that China will be among the world's largest e-Commerce market in the future. E-Commerce Cooperation between Korea and China has been undergone as a part of Korea-Japan-China e-Commerce. The outcome of e-Commerce Cooperation between Korea and China is less than that of e-Commerce Cooperation between Korea and Japan. Therefore, there must be the development of Vision and roadmap and organizational reform in Government, sufficient budget, consideration of digital divide and improvement of Korea-Japan-China e-Commerce Cooperation for e-Commerce Cooperation between Korea and China, The purpose of this paper contributes to improve the e-Commerce cooperation between Korean and China and to improve e-Commerce infrastructures in China by estimating current e-Commerce Cooperation between Korea and China and suggesting development strategies of Korea and China e-Commerce cooperation.

Based on the Results of Marine Meteorological and Oceanographical Observations during 1966∼1987 and the Ten-day Marine Report during 1970∼1989 by Japan Meteorological Agency, the possible area where the Japan Sea Proper Water (JSPW) can be formed is investigated by analyzing the distribution of water types in the Japan Sea. The Japan Sea can be divided into three subareas of Northern Cold Water(NCW), Polar Front(PF) and Tsushima Warm Current (TWC) by the Polar Front identified by a 6℃ isothermal line at the sea surface in vinter. Mean position of the Polar Front is approximately parallel to the latitude 39∼40。N. The standard deviation of the Polar Front from the mean position of about 130km width is the smallest in the region between 136。E and 138。E where the Polar Front is very stable, because the branches of the Tsushima Current are converging in this region. However, standard deviations are about 180∼250km near the Korean peninsula and the Tsugaru Strait due to greater variability of warm currents. In the NCW area north of 40∼30。N and west of 138。E, the water types of the sea surface to the loom depth are similar to those of the JSPW. This fact indicates that the surface layer of the NCW area is the possible region of the JSPW formation in winter.

The inheritance of resistance to gall mite(Eriophys macrodonis) in boxthorn cultivars was studied with plants infected in open field. Segregation of the F$_1$ generation from crosses between resistant cultivars(Japan 1 and China 1) and susceptible line(CL42-56) hits a 3 resistant : 1 susceptible ratio, and the segregation ratio was 15 : 1 in cross between Japan 1 and China 1. It is concluded that gall mite resistance seemed to be controlled by two duplicate genes(El and E2), such that E1e1E2e2 symbolize the genotypes of China 1 and Japan 1. However, F, generation from Chungyanggugiza and CL42-56 cross did not showed clear segregation pattern but continuous variation was observed against gall mite resistance when resistance was determined on the basis of the percentage of galled leaves. Results indicated that the inheritance of resistance in Chungyanggugiza may be polygenic and complex. Also, Japan 1 and China 1 has a strong potential as a source of gall mite resistance, and Chungyanggugiza showing less resistance still has a valuable source.
