The purpose of this paper is to examine the scope of the application of Preliminary Draft Convention, which will be fixed as international uniform rules soon, in relation to the CISG. First, this Draft Convention will cover service contracts as well as sales contract of goods, but the license agreement will be excepted because it does not transfer the complete property. Second, this will cover the commercial contracts(sales or services) concluded by data message fully or partially. Third, this will be applied in international contract regardless of contracting states or non-contracting states. As it is very difficult to confirm the places of business of contracting parties in on-line contracts, the first criterion to confirm them is the indication by the party in each contract. This presumption may be supplemented, if they are not indicated in the contract, by the location of the equipment and technology supporting an information system used by a legal entity for the conclusion of a contract. It is essential to establish an international uniform rules as soon as possible in order to activate the international businesses with on-line basis. Thus this author hopes that this paper will contribute to the clear understanding to the scope of application of Preliminary Draft Convention for which the UNCITRAL is under working.

In this study we presented the plans to activate the Internet Shopping Mall for GWmart under its present situation recording a rapid growth in sales and recognized as a local new distribution channel since its early stage, using the analysis that affects the purchases of consumers. On studying the reliance of a shopping mall, only the shopping mall image and the efficiency in providing information are significant. Regarding the concentration on the shopping site by shoppers, what becomes significant are the efficiency in providing information and the convenience in searching for products, which is one of the important factors in increasing sales, does not affect the reliance of a shopping mall and the concentration on the shopping site by shoppers. Therefore, this finding suggests that it is not easy to access the internet shopping mall when consumers go shopping for certain products. Because of this, it is necessary to change the design and structure of internet shopping mall to focus on the consumers. Moreover, this study showed that the efficiency in providing information to customers and the image of the shopping mall do not affect the consumers' intention to purchase, which means that shopping mall lacks in its information service and the management of its structure. To address this, it is required to advance the User Interface and contents of internet shopping mall.

This paper search the difference between the village groves for enclosing and the village groves for rest in Chinan-Kun region. Both charged 72.5%(37 groves) of all(51 groves). The form of village groves for rest was various, but that of those for enclosing was linear. The average area of village groves for enclosing was 2,755.4$m^2$ and that of those for rest was 661.2$m^2$. So village groves for enclosing was 4.2 times larger than that of those for rest. In function of village groves, it was identified that function of complementing vacant part was more important than of rest in human settlement region. In the transformation of village groves, the village groves for enclosing were transformed into other productive use than those for rest. Although the worship service were performed annually in the past, that were almost disappeared in present. The forest state of village groves were almost deciduous ones. In vegetation structure, the number of upper trees of village groves for enclosing was 5 times more than that of those for rest. In average appearing rate of upper trees, the village groves for enclosing was 2 times more than that of those for rest. The most principal dominent species of both in upper trec was Zelkova serrata. The species showing highly appearing rate of upper trees were Zelkova serrata, Carpinus tschonoskii, Celtis sinensis, Qercus acutissima, Pinus densiflora, Castanea crenata, Salix glandulosa. etc.

Health policies in many countries have come under critical scrutiny in recent years. This is because of increasing national health expenditures. Also many persons in health sector have been the perception that resources allocated to health services are not always deployed in an optimal fashion. And they believe that the scope of resources in health services is limited, there is need to search for ways of using existing resources more efficiently. A further concern has been the desire to ensure access to healthcare of various groups on an equitable basis. In some European countries this has been linked to a wish to enhance patient choice and to make service providers more responsive to consumers, while Korea integrated health insurance funds into single fund in 2000. Many European countries are under considerable pressure to review and restructure their health care systems. There are several reasons of pressure to reform. There are demographic changes, pattern of disease change, advances in medical sciences will also give rise to new demands within the health services, public expectations of health services are rising as those who use services demand higher standards of care. These circumstances require the change of health care delivery system based on hierarchical regionalism, which was basis of health care delivery since 1920s. Korea is also under similarly pressure to restructure our own health care systems. We will have good learning from OECD experiences. In this paper we reviewed and compared among OECD countries' various experiences.

This study aims to analyze the factors affecting in-hospital complication and length of stay in elderly patients with total knee arthroplasty. A total of 8,224 inpatients over 65 years old were selected from the national old inpatient sample data which was produced by Health Insurance Review and Assessment Service in 2016. STATA 12.0 was performed using frequency, chi-square test, t-test, ANOVA and multiple linear and logistic regression analysis. Analysis results show that ages(over 85), Charlson Comorbidity Index, district(metropolitan) for general hospitals and gender, district, beds(100-199) for hospitals are significantly influenced in-hospital complication. Statistically significant factors affecting the length of stay are gender, insurance type, depression, district, bed(300 over) for general hospitals and gender, type of insurance, Charlson Comorbidity Index, depression, district, beds(200-299) for hospitals. Based on these findings, the factors affecting in-hospital complication and length of stay were different depending on the type of medical institution. Accordingly, policymakers should analyze the differences in care behavior depending on the type of medical institution and expand policy and financial support to resolve them.

Recent requirements in component management of building systems have focused on the requirement for improving methods and metric tools to support component condition assessment and appropriate decisions for infrastructure owned facilities. Although engineers and researchers have focused on developing methodologies for component assessment in recent years but there is not enough attention dedicate to facilities and components that have been constructed. This paper is a literature study of scientific papers within the topic of component condition index system (CCIS) in the period 1976 to 2009. Infrastructure component condition index had existed for some 40 years. The purpose of this paper is to provide an overview of CCIS to identify the suitable method for component condition assessment during its service life. This paper finds that the focus of CCIS, surveyed in several aspects during the 40 years that have been investigated, from technology to measurement and from assessment function to component maintenance as an integrated part of the infrastructure component management. This study offers help to researchers in understanding the selection of an appropriate method for component condition assessment in building and non-building systems.
