The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and server, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority(CA).

As the production of new and renewable energy such as solar and wind power has diversified, microgrid systems that can simultaneously produce and consume have been introduced. In general, a decrease in electricity prices through solar power is expected in summer, so producer protection is required. In this paper, we propose a transparent and safe gift power transaction system between users using blockchain in a microgrid environment. A futures is simply a contract in which the buyer is obligated to buy electricity or the seller is obliged to sell electricity at a fixed price and a predetermined futures price. This system proposes a futures trading algorithm that searches for futures prices and concludes power transactions with automated operations without user intervention by using a smart contract, a reliable executable code within the blockchain network. If a power producer thinks that the price during the peak production period is likely to decrease during production planning, it sells futures first in the futures market and buys back futures during the peak production period to make a profit in the spot market. losses can be compensated. In addition, if there is a risk that the price of electricity will rise when a sales contract is concluded, a broker can compensate for a loss in the spot market by first buying futures in the futures market and liquidating futures when the sales contract is fulfilled.

The dual system in Korea already plays an important role in quantitative terms in the Korean lifelong vocational competency development system. However, since most of the existing dual system performance management plans in Korea focus on qualification-linked dual system, research on the effective performance management of the four-year university-driven dual system is very insufficient. This paper presents multiple measures for developing a performance management system suitable for the university-driven dual system to achieve qualitative improvement of the contract departments of the dual colleges or universities. As an approach to the end, a performance evaluation system is established by developing the evaluation items and indicators for the dual colloeges' contract departments. Next, it analyzes the needs of various stakeholder groups such as field teachers of the involved companies, students in apprenticeship and OJT professors of KOREATECH through FGI's and polls to diagnose the current operational performance, especially the causes of high drpout rates of the contract departments. From these results, the paper presents firstly the development of measuring methods for the developed performance indicators of the evaluation system and then a systemic performance management system which is based on 'input-transformation-outcome-feedback' structure. In addition, some measures for improving the high dropout rate and performance are presented from the viewpoints of each stakeholder.

The financial industry in which arbitration is most frequently resorted to so as to resolve disputes is the sector related to the securities industry. Most securities related disputes are raised from broker-dealer controversies which is not new in the Republic of Korea. The disputes between securities brokers and customers are very frequently settled by arbitration in the United States. But the arbitration in the securities area may deprive investors from securities regulation's protection. Introducing the United States' Federal Supreme Courts cases, the author explores the logic of how the pre-dispute arbitration agreement compatible with Securities regulations. However, the author insist the South Korea should more careful in accepting pre-dispute arbitration contract in securities area. Mostly because of the lack of more specific way to secure substantive fairness in securities arbitration. Also the author worries about the possibility of prevailing pre-dispute arbitration agreement in all of the securities investment contract without any other choices, or securities laws' protection. But the author also suggests to introduce public securities arbitration system of the States, and also insists the way to secure substantive fairness, or the application of securities regulations in securities arbitrations. Which may be the pre-requirements for the pre-dispute arbitration agreement in securities investment contract.

The aim of this paper is to investigate how the public procurement policy exerts an effect upon the technology innovation of the firm and to make alternative proposals how to reinforce the effect. Although the pubic procurement process based on its monopsonic idiosyncrasy implies the means to lead the firms' supply function, the present system has contributed a little to accelerate the technology innovation. In fact, the system is lacking of the evaluation capability referring to the technological computer among the bidding films. So as to reinforce the function of technology innovation of the public procurement policy, it is necessary to improve the procurement institutions, in particular bidding and contract system. Finally, the paper propose, on the on hand, to enlarge the application range of the total bidding system in order to apply more strictly the technology evaluation standards on bidding, and on the other hand, to multiply the competitive proposal and the incentive contract type.

Traditional banking systems of transactions are being replaced by FfinTech. Block Chain System can be a key point in Fourth Industrial Revolution such as AI, Big Data, IOT and also can be used as a tools of smart contract or smart payment systems in International Trade. If banking regulation is to be liberalized FinTech would be more activated in Korea and various attempts would be available especially smart payment in business. There are so many levels to be achieved from the time of contract to the time of clearance. We cannot expect speed and range of IT advancement and international trade, Block Chain system will challenge the traditional banking process. First, Block Chain Payment system can be used in P2P, B2B transaction and also T/T in small business. Second, Bit Coin transaction can be available within the parties without the Trusted Third Party. Third, By using of Block Chain system Traditional International Trade process can be altered.

The purpose of this paper is to study the current situations of trade financial EDI based on The BOLERO system, New BOLERO system, The NACCS system in Japan and The EDEN(Electronic DElivery Negotiable document) system and problems in application of marine insurance contracts. Entwined with the contracts of carriage in international sale transactions is a contract of marine insurance by which the goods are insured against maritime perils. In the thesis I tried to explain the problems of paperless marine insurance contracts based on problems in relating to formation of the transit insurance contract and replication the functions of the marine insurance policy electronically.

The purpose of the study was to identify the standards of quality management in contract foodservice companies. The subject companies were selected by convenient sampling and surveyed for their standards. The questionnaire consisted of 7 categories: managements of food procurement, menu, production, personnel, equipment, information system, and solid waste. As a result of the study, 60% of the respondents appeared to use standard recipes, 51.5% of them spent 21-30% of the total cost as a labor cost, and 70% were reluctant to answer the food cost. The half of the respondents had job description and specification, 74.76% had training manuals on foodservice and computer software program, and 80.6% had a training program for solid waste management.
