The rapid growth of economy in china leads to concentrate throughput volume of World to North East Asia. Ports in North East Asia have to cope with rapid changes in environments. In order for a port to compete in the global market, it must provide proper productivity and promptly services of port. The system of information hold a key in port-logistic industries. Most ports make every effort to set up and operate the system of Information. Busan port already set up the system of port-logistic information such as Port-Mis, KROIS. But it is not activate yet because of problems of security and certification and so on. The purpose of this paper is to make Model which can activate the system of port-logistic information. In addition to, We suggest definite and feasible model by group and types of port-logistic industry.

최근 국제적으로 물관리의 차세대 개념으로서 지능형 물관리(Smart Water Grid)가 활발하게 논의되고 있다. 우리나라에서도 일부 학자들을 중심으로 이에 대한 개념이 도입되고 있다. 현재까지 정리된 지능형 물관리의 개념은 최근 급성장한 정보통신기술을 활용하여 기존에 비효율적으로 운영되는 물관리의 시스템을 획기적으로 개선하자는 것이다. 따라서 이론적으로는 물의 생산, 정수, 배송 그리고 이용과 처리에 이르는 전 과정을 실시간으로 통합하여 관리하는 것이 가능하다. 국제적으로는 IBM과 Siemens 등과 같이 정보통신과 물산업을 선도하는 기업 주도의 기술개발이 진행되는 단계이다. 2000년대 초반에는 용수수급의 효율화를 위한 장치개발에 주력하였으나, 현재에는 용수수급과 관련된 제반사항에 대한 기술적 통합시스템 구축으로 적용범위를 넓히고 있다. 우리나라에서도 도시인프라 자료의 통합관리와 수질 모니터링 시스템 구축이 추진되었으며, 2010년 12월 발표된 새만금종합개발계획에서는 본격적으로 활용을 검토하고 있다. 그러나 지능형 물관리의 기술적 통합시스템 전략은 곧 심각한 제도적 장벽에 직면할 것이다. 아무리 우수한 기술적 시스템이 개발된다고 하여도 제도적 기반의 구축이 없으면 국민경제에 도움이 되는 현실적용에는 한계가 있다. 기존에 확립된 물관리의 제도적 기반으로는 한정된 지역의 좁은 영역에서 활용될 수밖에 없다. 이것은 우리나라의 물관리가 기본적으로 법적, 제도적, 행정적 차원에서 분리되어 운영되고 있기 때문이다. 본 연구는 지능형 물관리가 지향하는 기술적인 통합시스템 구축이 당면할 제도적 한계를 도출하고 이를 극복하기 위한 정책적 방향을 제시하고자 한다. 또한 2009년 국회에 제출된 물관리기본법(안)에 지능형 물관리의 개념을 도입하는 방안을 모색하고자 한다.

Internet is the most important element in the emergence of the Internet economy, which derives the creation of new firms and employment, and brings about the new ways of marketing and business. The emergence of the Internet economy and the rapid growth of the Internet industry have a great deal to changes in the spatial economy. Korea has experienced a rapid growth of the Internet industries, but few geographical studies have been done to explain the impact of the development of the Internet industries on the spatial economy. This research explored how Korea has developed as a nation of the strong Internet economy in terms of driving forces by demand and supply side. This research tried to build a data set for the Internet industries with the introduction of a new classification scheme and a measurement. The most important finding from this research was the spatial concentration of the Internet industries toward Seoul at the national level and toward the Gangnam area within Seoul. The rise of Internet industries has added attractiveness to Seoul which enjoys a kind of cumulative and circular advantages.

With the explosion of SNS(social network services) users, the social commerce market has emerged as a new consumer market, and will continue to grow in recent years. Despite the market environment, however, studies are lacking as to the causes of frustration that are hurting social commerce activation. This study is based on the 'Hezbollah' 2 Factor Theory and is a study of social commerce users' satisfaction and frustration factors. For this purpose, social commerce site characteristics and user characteristics were first derived from interviews and literature reviews to confirm their relationship to satisfaction and dissatisfied products. The results showed that the price discount rate, diversity, regional infrastructure, and e-commerce familiarity resulted in the impact on the definition of satisfaction, while the price discount rate, interoperability and innovation resulted in the definition of unsatisfactory goods. It also showed that satisfaction affects the definition of intended use. In particular, the price discount rate was found to be the only factor affecting the definition of unsatisfactory as well as affecting the definition of satisfaction.

While global production supply chains are expected to shift toward friendly or allied countries, pandemic-shoring such as nearshoring and friendshoring, due to increased protectionism and the reorganization of regional value chains in the wake of the global pandemic, the study found that economic rather than political factors are still at play in consumer supply chains. In the case of Chinese e-commerce market (C-commerce), the study attributes the rapid growth of the market to (1) related regulatory relaxations introduced to stimulate consumption after the end of COVID-19, (2) an increasing pattern of wanting to consume more for a limited income and (3) unconventional business activities to increase their share of the global consumption market. Through these phenomena, the production-consumption network is likely to develop into a more fragmented form, and the consumption network in particular is expected to become more fragmented, influenced by the digital technology war, a phenomenon of re-globalization.

With rapid growing of the Northeastern Asia, the interest for the connection of Infrastructure that was behind of interesting until now is getting larger. In a line of same connection, UN-ESCAP are forwarding transcontinental railway project, asian highway project et al.. And this study aimed at analysis on the effect that extended to a space by Korea-Japan undersea tunnel project. In aspect of a national land balanced-development to solve various problems such as overcrowding in capital region, unbalanced state by regions, weak exchange between South and North Korea, and weakness of national land basis to prepare for unification et al., this study consulted the economic potentiality model as a analysis method to examine an effect. In this analysis, I used 24 scenarios including all cases by combination of 3 scenarios for Korea-Japan undersea tunnel, 4 scenarios for transportation modes in the section of undersea tunnel, and 2 scenarios for adjacency infrastructure. Transportation modes in the section of undersea tunnel are railway, car-train, mixing way of railway and car-train, and mixing way of road and railway. Adjacency infrastructure applied railway and road. In all scenarios, Korea showed higher growth potentiality than Japan. Also, proposal plan C route relatively showed better in national land balanced-development than other proposal plans. The growth potentiality relatively appeared higher by buildup of a connection together with non-capital regions from the construction of Korea-Japan undersea tunnel. In aspect of Northeastern Asia, it resulted in a increasing of trade and chance of network formation in the region of Asia through infrastructure connection. But, in considering passenger and various factors that extended to the economic growth, this analysis have some limitation. Therefore, I hope that deep studies will continuously perform with various factors.
