Online exchange is a cost-effective approach to trade goods and information among multiple sellers and buyers. Shipping industry includes lots of global entities such as shippers, liners, ship owners and shipping agents. Marine insurance companies and ship repairers and many other groups are also supporting the industry. However, international shipping exchanges are located on few cities in the world. Its our motivation that a shipping market can be online so that market participants do the dealing while sitting where they are with more efficient manner, preferable price and larger pool of candidates of trading partners. This paper presents Korean governmental project of building a cyber shipping exchange. The exchange covers ship sale and purchase, charter, insurance, freight futures, repairs, supplying of ships oil and database service. The workflows of each business were analyzed and designed to fit for online environment. The project includes design of trading mechanism, online documents, data flow, data storage and security. Online match making and trading mechanisms such as auction, reverse auction, bid are used. The whole trading process involves multiple organizations and business processes. So, this Paper focuses on how each organization would play their roles so that users can complete transactions with integrated and transparent view. The online exchange selves also as maritime portal site that links to other sites for cooperation vertically or horizontally, and serves database and information in global perspective. This paper also issues and discusses the justification of an online shipping exchange

By the continued island-mainland bridging works, increased consumer demand for seashore regions and fundamental improvement of accessibility to metropolitan areas, rural service industries in the island areas has been rapidly developed in the past decades, and also, their functions differentiated geographically. In most island areas, catering and accommodation sectors have been expanded, while traditional trading sector decreasing. And the dominant power of public sectors has been increased but private ones decreased. So, the overall development trends of service industries in island areas would be considered as unhealthy for rural economic sustainability. As a tentative solution, it may be proposed that through the functional specialization/differentiation and efficient linking/networking of rural service industries with multifunctionality of countryside capitals, their spatial cohesion would be strengthened.

This study quantifies the dynamic interrelationship between the KOSPI index return and search query data derived from the Naver DataLab. The empirical estimation using a bivariate GARCH model reveals that negative contemporaneous correlations between the stock return and the search frequency prevail during the sample period. Meanwhile, the search frequency has a negative association with the one-week- ahead stock return but not vice versa. In addition to identifying dynamic correlations, the paper also aims to serve as a test bed in which the existence of profitable trading strategies based on big data is explored. Specifically, the strategy interpreting the heightened investor attention as a negative signal for future returns appears to have been superior to the benchmark strategy in terms of the expected utility over wealth. This paper also demonstrates that the big data-based option trading strategy might be able to beat the market under certain conditions. These results highlight the possibility of big data as a potential source-which has been left largely untapped-for establishing profitable trading strategies as well as developing insights on stock market dynamics.

Competitive and reliable maritime transport services benefit the economy as a whole, and are key efficiency factors for the production of both goods and services. Although maritime transport sector is very liberalized compared to many other service sectors, certain obstacles must be overcome before full liberalization of the maritime transport can be realized. Particularly, maritime transport services in Northeast Asia are regulated by a complicated and outdated system. To remove these barkers two approaches can be used: a regional trading arrangement approach and a multilateral approach via WTO. However, multilateral efforts are not likely to be successful in achieving any concrete progress towards maritime transport liberalization in the short- to medium-term in Northeast Asia. Consequently, it may be the best to take the following two progressive approaches and to make them work towards liberalization of the maritime transport market: a bilateral approach and a trilateral approach. A gradual process of liberalization would expand the market, help operators achieve economies of scale, promote the international division of labor and specialization, enhance the effective management of shipping services, and promote the long-term interests and welfare of the user by improving service quality and diversifying services. A liberalized and integrated maritime transport market in Northeast Asia should achieve both of these long-run policy objectives by benefiting both the transport service users and the transport service providers. In order to move the maritime transport liberalization programs as quickly as possible, it is desirable to establish a "Regional Maritime Transport Liberalization Committee." We suggest it to be a Tripartite (China, Japan and Korea) Committee initially, which can later expand its membership to include other Northeast Asian countries.

This paper presents a new object model, LOM(Lightweight Object Model) and an implementation method for the distributed trader in heterogeneous distributed computing environment including mobile network. Trader is third party object that enables clients to find suitable servers, which provide the most appropriate services to client in distributed environment including dynamic reconfiguration of services and servers. Trading service requires simpler and more specific object model than genetic object models which provide richer multimedia data types and semantic characteristics with complex data structures. LOM supports a new reference attribute type instead of the relationship, inheritance and composite attribute types of the general object oriented models and so LOM has simple data structures. Also in LOM, the modelling step includes specifying of the information about users and the access right to objects for security in the mobile environment and development of the distributed storage for trading service. Also, we propose and implementation method of the distributed trader, which integrates the LOM-information object model and the OMG (object Management Group) computational object model.

기계학습(Machine Learning)은 인공 지능의 한 분야로, 데이터를 이용하여 기계를 학습시켜 기계 스스로가 데이터 분석 및 예측을 하게 만드는 것과 관련한 컴퓨터 과학의 한 영역을 일컫는다. 그중에서 SVM(Support Vector Machines)은 주로 분류와 회귀 분석을 목적으로 사용되는 모델이다. 어느 두 집단에 속한 데이터들에 대한 정보를 얻었을 때, SVM 모델은 주어진 데이터 집합을 바탕으로 하여 새로운 데이터가 어느 집단에 속할지를 판단해준다. 최근 들어서 많은 금융전문가는 기계학습과 막대한 데이터가 존재하는 금융 분야와의 접목 가능성을 보며 기계학습에 집중하고 있다. 그러면서 각 금융사는 고도화된 알고리즘과 빅데이터를 통해 여러 금융업무 수행이 가능한 로봇(Robot)과 투자전문가(Advisor)의 합성어인 로보어드바이저(Robo-Advisor) 서비스를 발 빠르게 제공하기 시작했다. 따라서 현재의 금융 동향을 고려하여 본 연구에서는 기계학습 방법의 하나인 SVM을 활용하여 매매성과를 올리는 방법에 대해 제안하고자 한다. SVM을 통한 예측대상은 한국형 변동성지수인 VKOSPI이다. VKOSPI는 금융파생상품의 한 종류인 옵션의 가격에 영향을 미친다. VKOSPI는 흔히 말하는 변동성과 같고 VKOSPI 값은 옵션의 종류와 관계없이 옵션 가격과 정비례하는 특성이 있다. 그러므로 VKOSPI의 정확한 예측은 옵션 매매에서의 수익을 낼 수 있는 중요한 요소 중 하나이다. 지금까지 기계학습을 기반으로 한 VKOSPI의 예측을 다룬 연구는 없었다. 본 연구에서는 SVM을 통해 일 중의 VKOSPI를 예측하였고, 예측 내용을 바탕으로 옵션 매매에 대한 적용 가능 여부를 실험하였으며 실제로 향상된 매매 성과가 나타남을 증명하였다.

When existing trade creates a product, a series of processes is terminated when a seller or a buyer subscribes for transportation insurance and is guided through customs procedures according to the terms of the sales contract and then receives payment for it. Training practical Trade kowhow is also educated focusing on the procedures of these contracts. A new paradigm of the fourth industrial revolution was launched in the development of information communication technology and computer technology. Also, due to the Xinhuo tradeism triggered by the United States, the risk of commodity trading is further increasing. Currently, trade practical education of university and industry is carried out for most lecture and discussion. Since 2014, the curriculumof the department of trade has been increasingly managed by the NCS process. The curriculumof the department of trade department has the advantage of being managed in consideration of the characteristics of the company that wishes to find employment and the level of work content. Standardized, the curriculumcan faithfully reflect the characteristics of the company and the level of the work content. In the new era, a new educational method that reflects the trend of the 4th industrial revolution era is necessary. In this research, we propose that service trade practical education should be educated mainly on contracts, not on procedural basis as with traditional commodity trade education.

As volume of international trade is growing importance for service business and service trade are also increasing. Increasing importance of service trade in Korea is also a reflection of such international trading. In this treatise this writer did not address various topics in relation to international trade arising from service trade. But confined the topic to study of concept of service and concept and patterns of service trade. Depending on scholars concept of service may be varied and this holds true also with concept of service trade which also lends itself to various classification. Among them if the focus is concentrated to tax standard in international trade then it can be classified into service transaction. In other words classification can be made according to service trade separated from commodities transaction with embodiment of service and service trade accompanying commodities transaction. In this treatise this writer confined the topic to introduction of international service trade but issues arising in relation to such trade internationally are varied. For this reason more study on such topics will be required in future.
