This paper introduces the Cherry system, a user-independent blockchain donation system. This is a procedure that is delivered to the beneficiary's bank account through a virtual account when a donor makes a donation, so there is no difference from the existing donation delivery method from the user's point of view However, within the blockchain, Cherry Points, a virtual currency based on the user ID, are issued and delivered to the beneficiary, while all transactions and the beneficiary's usage history are managed on the blockchain. By adopting this method, there was an improvement in blockchain performance, with transaction processing exceeding 1,000 TPS in typical transaction condition and service completion within 21.3 seconds. By applying the automatic influence control algorithm to this system, the influence according to stake, which is an individual donation, is greatly reduced to 0.3 after 2 months, thereby concentrating influence could be controlled automatically. In addition, it was designed to enable micro tracking by adding a tracking function by timestamp to the donation ledger for each individual ID, which greatly improved the transparency in the use of donations. From a service perspective, existing blockchain donation systems were handled as limited donation delivery methods. Since it is a direct service in a user-independent method, convenience has been greatly improved by delivering donations in various forms.

Nowadays the flow of international trade is that there seems to appear economic block significantly because most countries contract FTAs, so our market condition is changing to a severe competitive situation. Korea which has 70% of foreign dependence of trade must get involved in regionalism, and also actively promote FTA more than any other countries. FTA on February in 2006, the pharmaceutical industry are anxious. The pharmaceutical industry in Korea has recently come to a crisis that it is hard to expect a growth due to structure of profit and a change for the worse of management. If Korea-U.S. FTA are contracted in this kind of situation, domestic pharmaceutical companies will be at stake. We can anticipate that FTA with the country that has a strong competitive power like U.S. affect negatively on pharmaceutical industry, because the industry doesn't have enough self-competitiveness. Considering this kind of surroundings, we need to present the policy to enhance competitiveness for damage limitation on pharmaceutical industry by Korea-U.S. FTA. Under this background, this research has groped for a direction to strengthen the competitiveness to develop pharmaceutical industry in quality. The competitive enhancement plan is presented which is divided into the government policy part, the R&D part, and the management part. Although Korea-U.S. FTA is analyzed to wither the pharmaceutical industry, it would be thought that it is a good chance to upgrade domestic pharmaceutical industry if we make the best use of it, and also to make in roads into foreign market.

Since 'The Act on Private Investment of The Infrastructure' was established in 1994, private investment as well as government's investment has been active on transport infrastructure. But investment of transport infrastructure has more risks than others due to overforecast of transport demand for ensuring project validity, and cost uncertainty arising from financial crisis, commodity prices and so on. In the case of Incheon international airport express, after 2 years and 6 months, Incheon international airport express is opened, Korail take over equity stake in private investor due to the problems of MRG(Minimum Revenue Guarantee) be contracted with private investor. Not only that, in other case of Yong-in light rail, it is ongoing for legal disputes between Yong-in local government and private investor on account of opening delaying. On current Investment Assessment System of Transport Infrastructure, Risk Management system on investment of transport infrastructure is inadequate because Sensitivity Analysis in economic efficiency have been performed on the simple method which only changes benefits, expense and social discount rate. For this reason, this study analyze risks for investment of transport infrastructure demand forecast, and rise to the management practice for every particular item.

As of 1 July 2000 a big reform was introduced into the Korean health care system: the separation between prescribing and dispensing of drugs (SPD reform). There was, however, a big financial stake associated with pharmaceuticals, particularly before the reform, because physicians as well as pharmacists were allowed to purchase drugs at much lower costs than the insurance reimbursement. In this respect, this study focuses on the change in income and profit of both doctor's clinics and pharmacies after the reform. Data from National Health and Nutritional Survey by the ministry of health and welfare were used to estimate the income or expenditure that are financed by out-of-pocket payment of the patients, while national health insurance data etc. were used for the estimation of the income or expenditure that is financed by insurers. Average annual income per doctor's clinic increased from 299 million won to 338 million won for the three years between 1998 and 2001, whereas average annual income per pharmacy increased enormously from 60 million won to 305 million won for the same period. Average annual 'profit' increase per each doctor's clinic caused by the reform itself was estimated to range from 50 to 83 million won, while that per each pharmacy, from 23 to 87 million won. In sum, while both doctor's clinics and pharmacies are beneficiaries of the SPD reform, its positive impact is particularly prominent on the latter.

This paper focuses on prototype management models of location conflict concerned with crematory facilities in Korea. Using causal loops and stock-flow diagrams, it examines behavioral patterns of key variables, which would contribute to developing objective evaluation criteria. After a series of simulation works, the paper finds that the top priority should be given to how to improve neighboring residents' perception, ahead of specific compensation issues. Otherwise, they are open to vicious cycles or impasse. Juxtaposing individual cases together, Pusan and Cheongju examples which experienced the extreme confrontation in the initial stage could succeed in resolving crematory location conflict, especially between local residents and the public authorities, as the latter has repeatedly guaranteed to the former higher standards of participation. The opposite was almost true for Seoul and Ulsan cases, both of which were drawn into a crematory location whirlpool, incrementally losing resident's participation base. These results imply that the proposed management models would enhance mutual understanding among major stake-holders in relatively a shorter time, not to mention the overall cost.

The sustainable development of local communities is faced with limitation due to poor infrastructure and lack of cooperation among stake-holders. To overcome such circumstances and thus to ensure balanced development of the local communities, the central government is driving construction of innovative cities mainly through transfer of public institutions to local cities. In this study, to contribute to the development of plans for the future agropolis' associated with the transfer of public institutions, efficient organization mechanisms of the agropolis such as basic structure and spatial allocation was examined through analyses of advanced cases(Sophia Antipolis, St. Hyacinthe Science Part Food Valley, Stoneleigh Park) of foreign countries. The analyses showed that the organization of agropolis were consisted of three main components; 1) agricultural and food industry complex conducting R&D, 2) service facilities(information, trade, consulting and advertisement) supporting agricultural and food industries and rural enterprise center in charge of a variety of events including exhibition, rural experience, education, and contest, 3) silver facilities such as hospital and town providing medical service and residence. Based on the results, inventories of facilities which are necessary in 'the future agropolis' and their spatial allocation were suggested.

With the rapid growth in construction sector, it becomes all the more important to assess the amount of Construction and Demolition (C&D) waste being generated and analyze the practices needed to handle and use this waste before final disposal. This serves waste management and disposal issues, paving way to waste utilization in construction industry from the sustainability point of view. C&D waste constitutes a major bulk of total solid waste produced in the world. In this work, an attempt is made to study the performance of concrete using water soaked Recycled Coarse Aggregates (RCA) in replacement levels of 0%, 25%, 50%, 75% and 100% to Natural Coarse Aggregates (NCA). Experiments were designed and conducted to study the performance of RCA based concrete. Further suitable performance enhancement techniques to RCA based concrete were attempted, to achieve compressive strength at least equal to or more than that for no RCA based concrete (control concrete). Performance enhancement study is reported here for 50% and 100% RCA based concretes. All four techniques attempted have given favorable results encouraging use of RCA based concretes with full replacement levels, to adopt RCA based concrete in structural applications, without any kind of concern to the stake holder. Further attempts have also been made to use Recycled Fine Aggregates (RFA) with appropriate modifications to serve as fine aggregates in mortar and concrete. Using RFA blended with river sand fractions as well as RFA with Iron Ore Tailings (IOT) fractions, have given good results to serve as fine aggregates to the extent of 100% replacement levels in mortars and concretes.

The purpose of this study is to evaluate policy formation stage of Meister high schools. The study analyzed the differences in the recognition of teachers, students, parents, and vocational education specialists about policy evaluation for policy formation stage of Meister high schools. The conclusions based on the results of the study are as follows: First, in context area the recognition of students showed relatively low level. It reflects that the principle of democracy is needed to the policy formation stage of Meister high schools. The participation of stake holders in the policy formation stage is essential. Second, in input area teachers recognized that the financial resources were sufficient. Vocational education specialists recognized that human resources, such as excellent teachers and Meister teachers, needed to recruited adequately. Third, many policies and institutions need to be established for Meister high schools. The Meister high schools should be selected based on the principle of equity. In the selection process vocational education specialists should be included for the principle of professionalism.
