It is widely accepted that public rental housing programs affect both the allocation of resources and the distribution of welfare. This paper explains institutional arrangements of public housing program in Korea and assesses the benefits of the program. In contrast to the previous studies which employed homothetic preferences, the benefits of the public housing were estimated based on non-homothetic preferences to allow for different income effects across households. Empirical results suggest that average benefit-cost ratio of public housing program is 0.91, and hence, the deadweight loss seems to be well-contained in Korean public housing program compared to other countries. However, the distribution of the benefits reveals that the transmission of the benefits should be improved to achieve the desired goals of residential welfare for low income families.

Dojuk-San is known to be effective for treating a urinary diseases and stomatitis. However, its effects on the bone marrow-derived mast cell(BMMC) mediated allergy and inflammation mechanism remain unknown. In this study, the biological effects of Dojuk-San ethanol extract(DJS) were evaluated while focusing on its effects on the allergic mediator in phorbol 12-myristate 13-acetate(PMA) plus calcium ionophore A23187(A23187)-stimulated BMMCs. An investigation was also conducted to determine its effects on the production of several allergic mediators including interleukin-6(IL-6), prostaglandin D2($PGD_2$), leukotrieneC4(LTC4) and ${\beta}$-Hexosaminidase(${\beta}$-Hex). The results revealed that DJS inhibited the PMA plus A23187 induced production of IL-6, PGD2, LTC4 and ${\beta}$-Hex. Taken together, these findings indicate that DJS has the potential using in the treatment of allergy.

The whole objective of two papers in series was to develop the framework of an information management system (IMS) for soil-contaminated sites. In this work, we investigated current status of information management in our country and the IMSs of developed countries such as USA, Germany, Netherlands, and Japan. Through the investigation, we made four suggestions which could be taken into account for developing the IMS's framework. Firstly, we need to append the amendments on definition of information management and opening to the public to the Soil Environment Conservation Law. Secondly, detailed guidelines for each cleanup phase need to be developed. Thirdly, in order to increase the access of the public into the IMS, we need to provide electronic data files (e.g., PDF files) for them. Finally, a sole institution need to be chosen to control efficiently the IMS. In the subsequent paper, we will develop the framework of the IMS, based on the results of this work.

To investigate the anti-cancer effects of n-butanol fraction of DoJeokSeungKi-Tang extracts(nBFD) in U-937 cells. MTT assay was used to determine U-937 cells proliferation. Flow cytometry was used to detect apoptosis. Bcl-xl anti-apoptotic protein and caspase-3, p53 pro-apoptotic protein were examined by Western blot analysis. nBFD inhibited the proliferation of U-937 cells in a dose-dependent manner. The cells treated with nBFD showed a typical apoptotic process by increasing sub-Gl peak. nBFD reduced uptake of 3,3'dihexyloxacarbocyanine iodide(DiOC6) a fluorochrome which incorporates into cells dependent upon their mitochondrial transmembrane potential$({\triangle}{\psi}m)$. nBFD induced in U-937 cells apoptosis mainly via increasing sub-Gl peak, regulation of Bcl-xl, caspase-3 and p53 protein.

While images and aerial photographs using conventional satellites have the advantage of providing data in a vast area, there is a difficult aspect: the limitations of filming and processing data in a particular region at a desired time and the repetitive filming of a short cycle. With the development of many new technologies to overcome these shortcomings, methods of building cadastral information are changing rapidly. In particular, unmanned aerial vehicles that deploy cadastral information quickly and accurately using UAV have increased interest in technology that obtains cadastral information. Therefore, the purpose of this study was to suggest the application of cadastral measurement tasks in areas subject to cadastral measurement using UAV. To this end, the Commission decided to compare and analyze the accuracy of high-resolution images produced by observation area and apply them to existing cadastral work using verified images and cadastral data. In this study, we will analyze the applicability of UAVs to their cadastral survey by analyzing the current status of legislation related to cadastral survey and the technical characteristics of UAVs and propose technological, legal and institutional improvement measures for introduction based on them.

This study examined the role of volunteer fire fighters in coping with great disasters in terms of community-based disaster management to provide some implications from a qualitative comparative case study between Korea and Japan. Kobe, which suffered from the Great Hanshin-Awaji earthquake in 1995, was the study area. The city experienced an inadequate institutional system and lack of disaster management infrastructure at the time before the disaster. The study indicates that Korea volunteer fire fighters are not prepared sufficiently to tackle great disasters in terms of the supporting system, capacity and role by analyzing improvement plans of Japanese Volunteer Fire Fighters after Great East Japan earthquake in 2011. The results of the case study suggests improvements in the disaster management system to provide cooperation between the central government and local government, core task distribution, and community-based disaster management.

This study is to find out empirically how the fear of crime is affected by the level of recognition of people. CPTED elements including natural surveillance, access control, utilization enhancement, territoriality securement, etc. Safety of residents could be considered and then increased when we plan, design, and operate a city. In Korea, CPTED is currently being applied to every town. However, it is not systemized and neither efficient, for there are no constraint provisions, and the foreign cases are not specifically customized to the current situation of the country. This study, therefore, aims to find the limits from analyzing related laws and regimes, administrative regulations, and applied cases, and to deduct improvement plans based on examined foreign cases.
