주택도시보증공사의 주택분양보증의 독점에 대한 쟁점들이 야기 되고 있다. 국토교통부는 추가보증기관을 지정할 경우 과도한 경쟁으로 수분양자간의 재산보호가 미흡하고 도시재생 재원의 약화를 우려한다. 독점 사업을 통해 주택시장의 안정화를 위한 주택공급정책이 원활하게 수행할 수 있다고 주장한다. 이는 공정거래법상 시장 지배적 지위 남용이라 판단되며 분양보증요건의 과도한 제한으로 사업지연 및 조합원의 재산권 침해를 발생시키므로 본고는 그 개선 방안을 제시하고자 한다. 첫째, 공정위 시장지배적 사업자의 지정제도 신설을 통해 민간 보증기관의 신규 진입이 가능하도록 한다. 둘째, 「공정거래법」 제63조(경쟁 제한적인 법령제정의협의 등)의 규제개선이 필요하다. 셋째, 「주택공급에관한 규칙」 제15조제2항이하 신설을 통해 국토부장관이 보증기관을 추가 지정할 수 있도록 하여 사업주체의 분양보증 선택권을 보장할 수 있다. 또한 다수의 보증보험회사 중 1개 이상을 지정하여 사회이익 배분의 효율성을 제고하여 주택가격 변동성을 낮출 수 있을 것으로 기대하고, 주택분양보증 경쟁 도입 찬반 논란에 따른 법적쟁점에서 6가지 법률적 근거를 들어 제언해 본다.

It is well understood that developing new drugs is one of the highest value-added businesses in a country; however, the current governments' spending in pharmaceutical research and development(R&D) is minimal in Korea. This paper suggests that different governmental bodies should take in charge of different stages of the R&D process in order to maximize the use of limited government research funding. First, during the initial phase of the drug development, including clinical trials, the Ministry of Education, Science and Technology is the most appropriate governmental organization to support the research. For later procedures such as supporting the industries for exporting developed drugs, legislative approvals, and building infrastructure for future clinical trials should be supported by the Ministry of Knowledge and Economy and the Ministry of Health and Welfare along with the Korea Food and Drug Administration(KFDA). The KFDA, which is the main governmental agency approving newly developed drugs in the market, will need to take a crucial responsibility in the initial phase of the pharmaceutical R&D by guiding the industries with timely and proper information. As a first step, it is recommended to set up and operate a center for supporting new drugs, so that the industries can facilitate the development of marketable drugs which meet customers' needs. Later, in order to expedite the process of exporting and getting approvals of the newly developed drugs from foreign countries, it is necessary to develop new approval system, which includes introduction of the Good Manufacturing Practice (GMP), mandatory validation system, and education program for supporting expertise. Lastly, the KFDA needs to take an active role in developing Korean pharmaceutical industries by communicating with other foreign governments with regards to the globalization of the Korean pharmaceutical industries. For example, as a follow up after the Free Trade Agreement(FTA), active discussion on GLP of Mutual Recognition Agreement(MRA) with the United States of America, should be seriously considered.

Privatisation has emerged within the past few decades as one of the most significant challenges to public ports and their governments throughout the world. More than forty countries have committed to some form of port privatisation thus far and they will quite likely be joined by dozens more by the turn of the century. A decision to privatise ports can be driven by a variety of forces. The most obvious is to relieve a financially strapped government by turning to the private sector for an infusion of capital required to modernise and sustain port operations, or to bolster the national treasury. Inefficient and costly port operations can seriously impair the competitiveness of a nation’s export industries and artificially raise the cost and thus constrain the availability of imported goods. Privatisation in certain circumstances therefore holds the promise of stimulating economic growth particularly for those whose livelihood depends directly upon port activity and trade. The main objective of this paper is first of all, to introduce a variety of methods of port privatisation after reviewing the reason why port facilities should be privatised. This paper also aims to make some proposals with which a port privatisation process in Korea can be improved after summarising the present Terminal Operating Company(TOC) system propelled by Ministry of Maritime Affairs and Fisheries.

In this paper, efficiencies of core technology development projects, conducted by Ministry of Trade, Industry and Energy, are compared. In the process, DEA (Data Envelopment Analysis) is utilized as a main technique for comparing efficiencies. For DEA, input oriented BCC Model is adopted with government grant, recipient expenditure, the number of participating institutions, and project duration as input factors, and the number of patents, the number of papers, and occurred sales as output factors. As a result, next generation mobile communication project turns out to be the most efficient project of all. Therefore, next generation mobile communication project should be benchmarked for the other projects to follow. However, these results should be used only for reference data since every project has a different objective and, of course, is run under a different environment.

This study investigates the key determinants of exchange rate (RER) misalignment for the period 1991 to 2020. The BEER technique has been used to estimate the degree of the equilibrium exchange rate. To explore the actual exchange rate misalignment and to assess the behavior of variables that are different in different regimes of undervaluation and overvaluation, the nonlinear technique of Markov regime-switching (MSM) was applied. The mean and variance of each regime are highly significant and show that undervaluation episodes have a low mean (116.139) and more volatility (1.229) while overvaluation episodes have a high mean (126.732) with less volatility (0.871). The findings show that MSM accurately identifies exchange rate misalignment in both regimes as separate incidents of overvaluation and undervaluation. Results further depict that misalignment of the RER is affected by terms of trade, net foreign assets, interest differential, government investment, and consumption decision. Results recommend that if policymakers want to use the exchange rate as a policy tool, they must first consider the drivers of the equilibrium exchange rate. As a result, any deliberate actions to address exchange rate misalignment must focus on the underlying fundamentals that drive the exchange rate.

A synthesis method for a chitosan-coated magnetic drug-delivery system of cisplatin is proposed. Here, cisplatin was conjugated to the surface of Magnetite ($Fe_3O_4$) nanoparticles via a (3-Aminopropyl)-trimethoxysilane (APTS) coupling agent. To reduce the cytotoxic effect of cisplatin, the magnetic drug was then encapsulated in chitosan (CS-cisplatin-$Fe_3O_4$) through the water/oil (W/O) emulsion method. The CS-cisplatin-$Fe_3O_4$ nanoparticles were synthesized in a spherical shape with a diameter of 190 nm. The cytotoxicity assay was performed using HeLa cells. The cisplatin uptake of the cells was determined using High Performance Liquid Chromatography (HPLC) to calculate the drug content. The controlled release of cisplatin was demonstrated by regulating the dissolution and diffusion of the drug through the chitosan matrix.
