The theme-type self-harvest concept proposed in this research will be applied as a relevant reference in planning and realizing urban-rural exchange facilities at the village level. The aim of this paper is to describe the concept, to characterize the self-harvesters and organic farmers involved, to illustrate the ecological, economic and social interaction and the possible constraints of the concept. What is more important, however, is to develop programs for consultants, organic farmers and green-minded consumers, to vitalize direct transaction. The proponents of self-harvest are convinced that this concept leads to ecological, economic and social benefits, which will help to design a sustainable food supply system for small, medium and large cities.

본 논문은, 개인 간 거래 C2C에 기반으로 해외직구 불법 거래에 관한 모니터링 시스템을 제안한다. 관세법에서는 해외직구 물품이 일정 금액 (미화 150불, 단 미국은 미화 200불)이하 또는 자가 사용 물품으로 인정되는 경우에만 제세를 면제토록 규정하고 있다. 과세를 면제받아 구매한 해외직구 물품을 온라인 등에서 되파는 행위는 무신고 밀수입죄에 해당한다. 그런데도 온라인 중고 사이트에는 이에 대한 되팔이가 증가하여 지속적인 관세법 위반이라는 사회적 이슈로 논란이 되고 있다. 따라서 본 연구에서는 해외직구 관련 불특정 거래 내용을 수집하고, 정보를 빅데이터 방식으로 데이터를 정제하여, 자연어 처리 등을 통해 모니터링 시스템으로 설계하여 판매자와 유사한 형태를 보이는 키워드 분석, 거래방식 분석, 동일성 판별 등을 분석하였다. 해외직구 물품의 불법 거래 단속에 활용이 가능할 것이다.

This study is in order to promote agricultural products sold in the rural village festivals direct transaction marketplace and enabled by a comprehensive user evaluation of the rural village festivals direct transaction marketplaces in universal design perspective, provide a design plan for your care and comfort of a rural village festival Direct Deals Marketplace there is a purpose. Thus, redefining the principles of universal design suitable for direct transactions rural village festival marketplaces, and to do this by reclassifying the design elements of the farmstand-type in a framework was developed 30 questions to evaluate items for Universal Design Evaluation. And, the selection of three villages along the rural village festivals scale and conducted a survey of Universal Design Rating. As a result, the overall assessment was positive for B villages of rural village festival marketplaces direct transactions, there was a significant difference with the other village. In particular, there was a notable difference in the fairness, efficiency, promotional, safety and hygiene. And, there was a significant difference in design elements for directing atmosphere by selling space, product display, hygiene. This paper presents the design suggestions about a rural village festivals farmers' market aspects of universal design for improvement of the marketplace as following, 1) placement for differentiation the markerplace and around sites in the festival place, 2) to build the operating systems of sustainable management for arrangement and organization during the festival, 3) to install the device for maintaining agricultural products freshness 4) to separate the sale of local specialty products and general food products, and 5) to locate the suitable space considering the visitors tour route in the festival place for large-scale festival.

This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e- marketplace, but also can be applicable to both public and private types of e-marketplaces. This solution is different from the most of the public e-marketplace solutions that their main sources of revenue are transaction commissions or transaction fees through the third-party intermediation. Instead, this solution provides an ASP (Application Service Provider) functionality for direct, dis-intermediated purchasing and sales-related transactions between suppliers and buyers. With this functionality, suppliers and buyers electronically commerce with each other without the disclosure of their transactions as well as transaction commissions.

This study investigates the relationship between family ownership and the stock price crash risk. It believes that this relationship would never be in direct connection. The authors design and then find that family ownership is predisposed, in the first place, to the related party transaction, then the related party transaction causes the future stock price crash. This study infers that employing the power of family ownership creates the Type I agency problem, although this is not relevant for the Type II problem. From the perspective of the hoarding theory, family ownerships produce opaque accounts by blurring financial information. The blurred information is probably hidden in the related party transactions. This study, therefore, splits these transactions into accounts receivable, other accounts receivable and other receivables. Finally, this research concludes that the family ownership affects related party transactions. These then are used as an instrument to influence the leaded related party transaction. The latest, leaded related party transactions influence the future stock price crash. This study infers that related party transactions are abusive practices, especially on the types of receivables. It implies corporate governance's revitalisation.

As a rapid development of electronic commerce transactions in these days, the security and private protection problems became more important matters under the electronic transaction base. Because electronic transaction using electronic documents be carried without direct person to person meeting, there can be the possibility to use other's identity illegally without notice, and very hard to verify authenticity of transaction as well. In addition, it is very hard to find out that the electronic documents on the process of submitting is forged documents or not, and also have much difficulty in maintaining transmitting secret. Therefore, to solve such problems on electronic commerce transactions and electronic documents, the digital signature and certification system with cryptography skill is inevitably necessary. As the wide use of digital signature together with beginning of digital government and financial transaction, not only the issuance of electronic certification, but certification market came to gradually expand. In Korea, after enacting digital signature act in 1999, the act contents were expanded to the wide range of contents complying with global standards from the end of 2001 to April, 2002, including the new clause of certification problems. And the act was put into operation now. Therefore, in this paper, we'd like to suggest development scheme through the investigation on electronic certification related problems, such as, concepts, procedures, service conditions here and abroad.

The construction of a Synchronous Reluctance Motor (SynRM) is simple and also highly economical because a stator from the existing AC motor can be used. Since the synchronous inductance in the Synchronous Reluctance Motor is an element that is proportional to torque, its exact value must be experimentally or analytically found for accurate control and performance development of the motor. In this paper, direct torque control (DTC) simulation is carried out to maximize the torque of the Synchronous Reluctance Motor and the fast response characteristics with the inductance value by the Finite Element Method (FEM). The response characteristics are compared through the proposed direct torque control and torque response characteristics that are based on the existing PI Control in order to confirm the fast response features. To test the performance of the direct torque controller, the torque response is analyzed with variable speed and load condition.
