The technique of information-communication rapidly developed has made it possible for us to do business through Internet. Electronic commerce was increased rapidly by the explosive development of the inter and communication revolution. E-Commerce has created a fundamentally new way of conduction and will change drastically accepted ways of doing business. Normally international trade has been formulated in a way that exporters and importers meet face-to-face and contract and pay by letter of credits. For the global electronic commerce to vitalized, the outstanding matters should encourage the creation of infrastructure of information security and new models in the field of electronic payment systems, electronic commerce agreement for remedy, adapting electronic date interchange in transport documents and negotiability of electronic bills of lading. The payment systems such as electronic fund transfers, tradecard system and electronic letters of credits issued by SWIFT system permit the parties concerned(sellers, buyers ad service providers) to settle payment electronically. Still they are many limitations for complete international electronic transactions. The following measures have to be taken to vitalize electronic trade transactions. It is needed to acquire information security such as authenticity, integrity, non-repudiation and confidentiality. All kinds of documents need to be replaced by electronic date exchange and the legal structure of international convention, national law for electronic payment systems have to be completed. Also a detailed guide of the banking operation and developing rules for electronic letters of credits need to be provided to adopt eUCP rules for the electronic presentation of documents.

It is essential that the evaluation of official development assistance (ODA) projects is conducted based on empirical research for the performance and improvement of the project. This study intended to quantitatively figure out the actual status and performance of ODA projects. The performance of the Rumpin Seed Source and Nursery Center project implemented by the KOICA was evaluated in items of relevance, efficiency, effectiveness, impact, sustainability, which are OECD Development Assistance Committee(DAC) evaluation criteria. From August 26, 2019 to August 29, 2019, a survey was conducted on 50 visitors and 54 stakeholders of the Rumpin Seed Source and Nursery Center. Through on-site survey, problems in the donation project and operation in Indonesia were identified and measures for improvement was grasped. As a result of the study, the value scored by OECD DAC evaluation criteria of the Rumpin Seed Source and Nursery Center project based on the Economic Development Cooperation Fund(EDCF) evaluation grade was evaluated as a very successful class in all items. The average score of the recognition question was 4.08 points for visitors and 4.08 points for stakeholders, and the average score for the satisfaction question was 4.37 points for visitors and 4.11 points for stakeholders, which were high overall in both groups. The main factor that affects the project awareness of the visitors was the fact that the Rumpin Seed Source and Nursery Center was created based on Korean technology, and it was confirmed that Indonesia's own items related to similar projects had a great influence on the project satisfaction. In the case of stakeholders, project support in Korea affected their recognition, and it was found that relevance, efficiency, effectiveness items had the greatest impact on the level of project satisfaction of stakeholders derived from the DAC individual evaluation results. Efforts are required to increase the main factors by reflecting the results of each item and to preserve and maintain the project. This study is significant in determining the performance of the ODA project based on empirical data, and it is believed that it can be used as basic data for supplementing and strengthening the project in the future.

Nepal is a landlocked mountainous country in South Asia, located between China to the north and India to the south, east, and west. As such, wastewater management has become one of the most significant problems in urban area of Nepal. In Nepal, the centralized wastewater treatment systems were dysfunctional due to high cost of operation, discontinuous power supply, lack of proper maintenance and proper technical workforce to address the issues. As such, constructed wetlands (CW) were applied to treat various secondary wastewater as alternative to wastewater treatment facilities. Generally, efficiency and sustainability of CW technology depends on proper operation and maintenance and active community involvement. This study summarizes information about 26 CW in Nepal. Specifically, factors including data banking, removal efficiency, quality of discharged water, compliance to water quality standard of Nepal and operation and maintenance were investigated. Considering removal efficiency per pollutant, Ka-1 achieved the greatest reduction for most pollutant followed by B-1, L-3, Ka-5 and K-1. Nepal has practiced CW technology for more than 2 decades but currently, development of technology was interrupted by the inefficient performance of existing facilities. Public awareness about the technology, natural disaster, unavailability of specified substrate materials, lack of fund for further research and experiments has hindered the expansion of technology. In spite of these concerns, CW was still proven as an alternative solution to the present wastewater problems in urban areas of Nepal.

This study is aimed at evaluating the present management status of the rural special production area development projects and identifying managerial problems to propose new direction of the political countermeasures for the projects. In the con text of implementing the five year's economic developent plans for the past three decades, agricultural production and farm-household income have also been grown rapidly. However the income gap between rural and urbarn laborer, as an internal problem, has widened during the decades and the UR problems concerning free trade of agricultural products, as an external problems, are now agonizing the small-holder farm economy in Korea. The internal and external farm problems could be solved through improvement of agricultural structure and provision of off-farm jobs for farm household income increase. As a part of the off-farm income sources, the rural special production area development projects have propelled by the government throughout the country. The main problems to be solved for the successful implementation of the projects are as follows : 1. Present loan amount by the financial fund was estimated at 6-7% of the total installation costs required. To expand and implement the project successfully, enough financial credit support with favorable terms and conditions have to be considered by the government. 2. The operation patterns of the special production area development project should be recommended from the view point of cooperative and private operation to maximize farm household incomes including profits, marketing charges and dividens. 3. Improvement of the marketing channel of the products and marketing information through TV program and other mass communication should be implemented strongly to promote marketsales by the financial supports of the government. 4. In connection with the off-farm income increase, the population migrating to urban area in outside Chungnam province equivalent to 10-12 thousand persons with age of 20-49 years should be taken into account politically to be employed in the projects in the province. 5. Surplus farm labors should be created by means of improvement of agricultural structure including large farm management with farm mechanization and job opportunities have also to be provided in connection with the rural special production area development projects. The two imminent subjects are the prerequisites to increase off-farm incomes for the farmers living in Chungnam province. 6. Required credit supports for investment and operation costs of the projects should be taken actions by the government.

This research suggests for efficient operation of the e-commerce guarantee financing system in domestic industries by reviewing the definition, current situation and problems of the e-commerce guarantee financing system in operation since 2001. Throughout the 10 years of the e-commerce guarantee financing system's implementation, technological development has solved many previously concerning factors. The goal of the study is to resolve the current issues of the e-commerce guarantee financing system and offer means by which to expand the accessibility of the system to domestic industries and further assistance to firms already using the system. One of the primary policies supported by the research is the reallocation of funds from archaic means of exchanging finances to the modem e-commerce guaranteed financing methods because of the increased transparency of the trading. Specifically, the funding operated by government guarantee agencies requires systematic promotion, justifying subsidies and tax breaks to companies that are using e-commerce guarantee financing because of the increased overall transparency. In addition, the benefits of e-commerce guarantee financing as a means of funding are numerous: the promotion of good business, relaxation of credit ratings for company loans, construction of the mobile operating system for small businesses, and creation of policy flexibility in operating fund agencies run by government. Future research areas include continued collection and analysis of the above data provided and new market feedback such as direct poll surveys of the operating staff in companies using e-commerce guarantee financing agencies.

In this study, we analyze how the difficulties of e-learning firms' management affect to the maturity of the practical use of e-learning research & development (R&D) policies. And we explore the method that can enhance the effectiveness of policy. In the pursuit of this purpose, we use the 2012 South Korea e-learning industry survey data. Using variables of recognition of policy, experience of policy, and intention to use of policy, we find the maturity model of six stages. And we analyze the impact of the difficulties of operation, technology development, marketing to the maturity model. As a result, the more e-learning firms have problems of fund management and technology commercialization, they are located the higher maturity of the use of policy. Based on the results of these studies, we discuss the implication for how can enhance the effectiveness of policies.

This paper investigates efficiency analysis to IT HRD programs in the dynamic perspective. First, empirical result shows that government fund of IT research center is significantly associated with SCI thesis and the more trial goods and SW development is connected with the more patent and technology transfer. Second, ITRC program has been operated efficiently since 2000. Finally, dynamic efficiency analysis implicates that ITRC program is more efficient than other IT SoC program and foreign student support program. The reason why ITRC program is more efficient is generated not from the effect of imitation by catch-up strategy to developed HRD programs, but new operation system introducing and utilizing HRD performance system.

The purpose of this study is to figure out the differences of the inflow rates of Sewage Treatment Plants (STP), invested by public fund or public-private partnership (PPP). This paper finds that the average ratio of sewage inflow according to facility capacities (medium and small scale STP) was either nearly below 30% or above 100% in the first year. As the size of STP increased, there was decrease in the accuracy of demand assumption. This was because the operation time when the ratio of sewage inflow was uniform was different according to the size of STP, whereby the time was short when the STP were small. The design average ratio of sewage inflow was 10% larger than the real average ratio; this was considered overdesigned. In the case of a plant built by the PPP scheme, the average ratio of inflow of the STP before an abolition of MRG was larger than after the abolition of MRG. This may be explained by moral hazard from too much reliance on MRG. After the abolition of MRG, the demand risk of PPP was shifted from a PPP project to a conventional project.

This research is written for offering an approach to activate the stagnated industry of the tourist farm through analysis of the current operational problems and situation on some existing tourist farm nominated as such by the authority. There will be some considerations from three different categories : local autonomous groups, tourist farm associations and farm owners. On the other hand, it is assumed that this research can also be utilized as a basic material for activating the tourist farms in the suburban area of Taegu City. The operational problems in the suburban area of Taegu City are as follows : lack of a specialized Product development, the farm operation fund, lack of operational or management ability, lack of public information, etc. There are other Problems regarding law, institution and supporting : complexity of the current system involving all kinds of permission, shortage of financial and taxation supporting, lack of training an expert manpower, lack of ability and cooperation of a deskclerk in charge, etc. Here are some suggestions taking into consideration a respective sector of local autonomous group, tourist farm associations and farm owners for activating the tourist farms in the suburban area of Taegu City. First, a mental turnabout toward a tourist farm is needed from local autonomous groups. The law and institutional base should be arranged while the financial and taxation support is materialized. Second, tourist farm associations should amend or reinforce the existing institution to refresh the current recognition toward the tourist farm through many publicity activities. On the other hand, they should develop the overall tourist farm industry into a better service industry of the rural community by keeping an active system of cooperation with other related groups. Finally, It is advised that they should conceive farms and facilities which can symbolize the tourist farm from the stage of the first construction. In addition to a four-season souvenir development, an effective publicity activity and rational investment management. Above all, they should train themselves in terms of a service spirit before they see the prosperity of the tourist farm community.

To operate a large structure or a high-rise building, elevator is essential. Nevertheless, elevator breakdowns or accidents have been consistently reported. When the accidents are not serious, the records are not reported and cumulated in the Korea Elevator Safety Agency. Additionally, in case of replacement or repair of the parts of elevator, conflicts about the person responsible for the expense of the replacement or repair are frequently occurred. However the record of accidents is not decreasing and the conflict about the fund of elevator repair is serious. So, it is needed to reduce the elevator accidents or malfunction, the operation stop of the elevator, the conflict between building owners and users. Therefore, in this study, the elevator maintenance procedures during defect liability period, the notification procedure in case of breakdown or accident elevator, the direction of elevator maintenance contracts, the direction of the elevator inspection were suggested.
