Transfer pricing is a matter of concern for countries. It affects the interests of the parties involved in the commercial transaction. Through manipulation of prices in transactions, businesses take advantage of tax rates in a country to adjust profits for economic gain. This affects the fairness and rationality of economic transactions between related parties. The article uses a two-year time series from 2018 to 2019 of 50 foreign direct investment enterprises in Vietnam. The article uses ordinary least squares to test the hypotheses of the research model. The article uses four independent variables related to ownership structure affecting transfer pricing decisions including total ownership, organization ownership, concentration ownership, and area ownership. Research results show that two variables have a positive influence on transfer pricing decisions including total ownership and organization ownership. Organization ownership has a higher degree of influence than total ownership. To be able to control transaction activities related to transfer pricing, Vietnam's state management agencies need to pay attention to perfecting the legal framework based on supplementing and amending regulations related to transfer pricing. Legal regulations need to be regulated based on international common practices to ensure uniformity on a global scale.

This study has aimed to compare an emission trading system (ETS) in the EU and Japan that introduced the scheme prior to Korea and provided the latter with a benchmarking model. Especially, the EU has a reputation for its well-organized and evolving system, and Japan has also successfully established the system despite its similar condition with Korea, such as an industrial structure and the degree of energy dependence. However, there are noticeable differences between the EU and Japan in their ETS. Whereas Japan has focused on securing certifications in CDM as the implementation of Kyoto protocol, EU has shown a tendency to transform the trading market from a parallel structure of EUA and CER transaction to only the EUA transaction after ending of 1st commitment period of the Kyoto Protocol. Since the differences were mainly caused by not only in a design of the system but also in internal governance and their national circumstance, it is meaningful to analyse the Korean case with a similar framework. This study may contribute to designing an appropriate system for emission trading in Korea through the comparison of the EU and Japanese case.

The development potential of the aquaculture industry is very high, but there is no financial support for investment except for the government, policy funds, fishery funds, etc. Therefore, we would like to propose a contract transaction in the aquaculture industry. This refers to a forward contract between a producer (fish farmer) and a buyer (mainly a processor or marketer) that stipulates the production and supply of fish products at a predetermined price, but it also refers to an "equity participation type" contract in which both producers and buyers can participate. In other words, it is a model in which part of the fish farm is produced in a way that meets the conditions of the buyer, and part is produced by the producer. This study aims to establish the basic contract trading process. It provides an academic approach to prevent adverse selection and moral hazard due to information asymmetry. It also provides an idea to converge the aquaculture industry with the financial industry using Pecking Order theory. By doing so, we have made it possible for venture capitalists to invest with confidence and provided a process for investors to resolve their concerns, paving the way for the aquaculture industry and the financial industry to develop together.

In the large scale B2B transaction like buying Express-Train or selling Daewoo Motor, a tremendous amount of variables and factors of chaos functionate in it directly or indirectly. To get effective information processing on the so called complex system like this, it should be possible to unite the global insight power of the human being and the local computing power of the machine. In this paper, we suggested a union model of human being and machine using Hugent concept. Hugent is defined as an agent model which allows us to chemically unite the human's component and the machine's component in terms of information processing. In this paper, we showed that some typical problems contained in the complex system can be treated more easily through the suggested Hugent concept.

Databases are critical to business information systems, and RDBMS is most widely usded for the database system. Normalization has been designed to control various anomalies(insert, update, and delete anomalies). However, normalized databese design does not account for the tradeoffs necessary for the performance. In this research, we develop a model for database desin by denormalization of duplicating attributes in order to reduce frequent join processes. In this model, we consider insert, update, and delete costs. The anomalies are treated by additional disk I/O which is necessary for each insert and update transaction. We propose a branch and bound method for this model, and show considerable cost reduction.

We develop a probability model to evaluate information security investment portfolios. We assume that organizations install portfolios of information security countermeasures to mitigate the damage such as loss of the transaction being processed, damage of hardware and data, etc. A queueing model and Its expected value analysis are used to derive the lost cost of transactions being processed, the replacement cost of hardwares, and the recovery cost of data. The net present value for each portfolio is derived and organizations can select the optimal information security investment portfolio by comparing portfolios.

In the catalogs that have presently been under research, the product information cannot be represented in a classified form but it also fails to be well defined, lacking the description of detail information for various products on a systematic fashion. And the product information is duplicated on its representation. In this study, an implementing model is to be proposed to analyze and classify the information that can be in use of describing various products, and to describe an integrated products information for various types of products while making up for the weak points of presently available researches. Also, this study shows that it is possible for the proposed model to represent various units of product information with presently proposed model applied to computers and book products in high demand of transaction, and by implementing electronic catalogues in the existing researches to prove its efficiency.

EDI is fast becoming the standard way of exchanging business documents, not only in this country but throughout the world. The purpose of EDI is currently being used for all the most common business transactions such as purchase orders, invoice, quotes, bill of lading, status reports, receiving advices; and also for some very specific transaction. Thus, the purpose of this study, by way of literature survey and survey research are to find the effectiveness in EDI Service of Clearance Physical. The model of the Trust Dimension and EDI Provider Loyalty in EDI Service of Clearance Physical is tested here using data from 163 samples. Based on the research model, a comprehensive set of hypotheses is formulated and a methodology for testing them is outlined. some of the hypotheses are tested empirically to demonstrate the applicability of the theoretical model. In examining the relationships of the Clearance EDI determinants factors, Trust and e-loyalty show in significantly by customs practice trust, clearance EDI, EDI provider trust and clearance EDI loyalty. but that show in not significantly by a list of names, EDI benevolence.

This paper focus on building online trust in electronic commerce between partner that have never traded with each other before, the so-called first trade situation. For this, this paper proposes the model to build trust for conduction first trade transaction in e-trade(so-ca1led Trust Matrix Model : TMM). The TMM is based on the idea that for business to business electronic trade a balance has to be found between anonymous procedural trust, i.e. procedural solutions for trust building, and personal trust based on positive past experiences within for first trade situation, because of the lack of experience in these situations. The procedural trust solutions are related in the notion of institution-based trust, because the trust in the procedural solutions depends on the trust one has in the institutions that issued or enforces the procedure. The TMM can be used as a tool to analyze and develope trust-building services to help organizations conduct first -trade electronic trade.
