In the environment of protectionism and bilateral trade agreements, Korea has promoted the conclusion of FTAs for its export-oriented trading policy, and 16 FTAs have entered into force at present. The main goal of this paper is to introduce the ISI system and its benefits and to extend the preferential rule of origin regime by using the Integrated Sourcing Initiative in the U.S. Code of Federal Regulations. The ISI illustrates with impressive clarity the fact that it considered as a tool of expanding the geographic limit of states and maximizing the global sourcing strategy of multinational corporations, allowing the developing countries to gain access to the market of developed ones that avoid the complexity and costs of many rules of origin regimes. This paper utilizes the literature research and analyzes a case study of FTAs which have adopted the ISI system. In conclusion, it presents several implications of additional measures to satisfy rules of origin in Korea's existing FTAs relating to the global supply chain strategy.

This paper analyses a number of important areas relating to methane production in ruminants, consequent hazards and different methods of reducing this gas. Clearly methane not only affects on the environment but also on the economy of animal production. Several factors including feed, species, microbes, rumen environment, etc. are responsible for methane production in animals. Although methane production can be reduced by chemical manipulation, defaunation and strategic feeding, the latter was found to be effective because the method is easier to follow than the others. Furthermore, feeding technology could play an important role in reducing methane production particularly in developing countries because of its relative cost effectiveness. however, it needs to compare to what extent it could reduce methane production as well as cost of animal production. Therefore, research program needs to be concentrated on the appropriate feeding system to reduce methane production, consequently pollution and cost of production particularly in developing countries.

Many software reliability growth model(SRGM) have been proposed for past several decades. Most of these propositions assumed the S/W debugging testing efforts be constant or even did not consider them. A few papers were presented as the software reliability evaluation considering the testing effort was important afterwards. The testing effort forms which have been presented by this kind of papers were exponential, Rayleigh, Weibull, or Logistic functions, and one of these 4 types was used as a testing effort function depending on the S/W developing circumstances. We consider the methology to evaluate the SRGN using least square estimator(LSE) and maximum likelihood estimator(MLE) for those 4 functions, and then examine parameters applying actual data adopted from real field test of developing S/W.

The constructivism is an important stream of the recent trends of mathematics education. In order for students to construct their knowledge for themselves, above all, it should be a prerequisite that they participate in actively, Using games helps students to participate in learning mathematics actively. I think, up to now, mathematics teachers use games mainly for motivation and it does not connect to true learning mathematics through using games. So, the purposes of this study are developing the mathematical games connecting to mathematical contents closely, designing the teaching models to connect game activities to learning mathematics, and developing several teaching plans using games to mathematics class. In this study, I propose what conditions 'good' game should have, classify games as practice game, concept learning game, and strategy game, and develop 43 games from 1 to 6 grade. And I design the teaching models depending on the game types and develop the teaching plans.

One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. In-situ pavement performance can be considered a response variable to many project input variables, such as design, construction, and traffic loading effects. If we are to fully understand the component of pavement performance and specify the inputs through design and construction specifications to achieve that performance we must develop quantitative relationship between input and response variables through a scientific, fully integrated Pavement Performance Analysis System (PPAS). Hence, the objective of this study is to design a database model required for developing an effective database template that will allow analysis of pavement performance measures based on design and construction information linked by location. In order to select the most appropriate database model, a conceptual database model (Entity Relationship Model) and dimensional model, which is believed to be the most effective modeling technique for data warehouse project, are designed and compared. It is believed that other state highway agencies could adopt the proposed design strategy for implementing a PPAS at the discretion of the state highway agencies.

The balanced scorecard has drawn attention from many researchers in various fields since its appearance in 1992. It became a norm for performance evaluation framework in many areas, such as marketing, information system evaluation, strategic planning, etc. Centered in the large companies in Korea, the balanced scorecard has been popularly used as a performance evaluation tool for human resource management. Now we Question its applicability to performance evaluation tool even in small business. This study tried to apply the balanced scorecard in developing an information system for performance evaluation in a small business. The study showed that the balanced scorecard can be nicely used in small business as a performance evaluation tool. The process of developing an information system is described in detail. The practitioners are to obtain a lot of insights in designing their human resource management systems from the study results.

As the development of artificial intelligence (AI) technology spreads to various industrial sectors, diversity in AI utilization rapidly increases, creating rich user experience. In addition, AI is required to solve various social problems through the use of public data. The spread of AI utilization across all sectors will continue, covering such industrial and public demands. This article examines the domestic and international trends in AI utilization technologies and establishes the direction of research and development (R&D), which is highly consistent with Korea's AI policy. ETRI, which leads AI's national R&D, has used its experience to establish AI R&D implementation strategies as well as technology roadmaps for the utilization of AI to improve individual quality of life, continuous growth in society, industrial innovation, and the solutions to public societal problems. In addition, it has derived tasks and implementation strategies for developing AI utilization technologies in 10 major areas including medical services.

A repository has been conceived as a critical weapon for managing organizational information resources. The system can help control the heterogeneous data in a variety of CASE (Computer-Aided Software Engineering) tools. However, current repository systems have limitation in creating a synergetic effect by integrating information resources. Therefore, it is important to develop an integrative repository system, called Enterprise Repository System (ERS). This paper (i) defines ERS on the basis of a framework for repository systems, and (ii) suggests an ERS architecture and its detailed components. Finally, a real-life case of developing ERP repository system is illustrated according to the proposed architecture and components. This illustration may demonstrate the usefulness of this research for help developing an advanced repository system.
