  • Most local agencies such as counties and small cities continuously express difficulties in making technically and financially defensible decisions on their pavement infrastructure maintenance and rehabilitation. Unlike pavement systems managed by state highway agencies, the total lane-miles of many local pavements are significantly short and they are managed by a limited number of staff who typically have multiple responsibilities. Most local agencies also do not have historical pavement performance data and the lack of a systematic decision making framework exacerbates the problem. A structured framework and an easily accessible decision support tool that reflects their local requirements, practices and operational conditions would greatly assist them in making consistent and defensible decisions. This study fills this gap by developing a systematic pavement treatment selection framework and a spreadsheet based tool for local agencies. It is expected that the proposed framework will significantly help local agencies to improve their pavement asset management practices at the project level.

  • In 1980s, studies on the river environment and the management techniques to maintain the quality of water achieved actively. From the beginning of 1990s, the concept considering the river ecology and conservation in urban area have been introduced in Korea. Recently, some environment friendly projects on the rivers have been executed and some are under way. Many small rivers in rural areas have been maintained considering landscape and partly ecology. However until the pilot project named Songsam drainage channel project started in 1998, there were no studies and projects on the irrigation and drainage channels considering environment friendly maintenance. Korea Agricultural and Rural Infrastructure Corporation (KARICO) is going to introduce environment friendly and naturally favorable maintenance technique when the new projects to reform the irrigation and drainage channels are planned. Irrigation channel in O-dong project site in Yeomsan-myeon, Younggwang-gun was designed considering environment friendly consolidation and maintenance.

  • Neuroendoscopic surgery is performed because it causes minimal damage to normal structures, carries a lower rate of complications, and achieves excellent outcomes. Surgeons using an endoscope and related instruments can perform complex operations through very small incisions, which is especially useful for minimally invasive procedures for the brain and spine. Neuroendoscopic surgery is now performed in cases of obstructive hydrocephalus, various intraventricular lesions, hypothalamic hamartomas, craniosynostosis, skull base tumors, and spinal lesions. This review discusses the brief history of neuroendoscopy and the current state and future perspectives of endoscopic surgery.

  • This paper deals with the result of an analysis on the effect of the power generation by municipal solid waste(MSW)-refuse derived fuel(RDF) and the introduction of tipping fee sharing between RDF manufacturing and power generation project. As a model case for the MSW generated at small and medium cities in our country, an analysis of the RDF power generation and Tipping fee sharing shows that 1) MSW amount of 7,800* $10^3 $t/y could produce 1,950*$10^3$t/y of RDF 2) Electric power generated by MSW-RDF could supply 290,000 households/year and 98,548 C-t/y of $CO_2$ could be reduced. 3) Tipping Fee should be shared by the considering of the contents of project of both side between RDF Production and power generation.

  • Recently, with the policy balance development in the country, Ministries of the government as managers related each of regional projects have prepared pan-governmental support system to achieve Making Livable Area Policy. This study is analysis result of investigation in 2007 authorized cases of MLCP(Making Livable City Project) which Ministry of Construction & Transportation have propelling from city and rural-urban area of town, myeon and dong, to rural area of small village size. Areas chosen for MLCP have the active participation of inhabitants, and to promote successfully project, need to support system and originality for area. Such projects will finally increase the life quality, and make life-spaces wanting to live in the area.

  • This article is summary of 'Korean Green New Deal' project which strives to revive Korea's Top 4 rivers for the next four years, between 2009 and 2012. The purpose of this project is balanced national development and recovered regional economy, creating new jobs. Details of the 'Korean Green New Deal' include means to reinforce obsolete embankments and to recover the river ecosystem by maintaining sedimentary soil, to install small- to middle-sized dams and flood control reservoirs and to establish eco-friendly reservoir for emergency water supplies. The project is expected to generate 190,000 new employee and create 23 trillion won worth production inducement effect, contributing in the revival of regional economies.

  • Membrane filtration is a promising technology for efficient solid/liquid separation in water purification. In FY 1991, the Ministry of Health and Welfare, Japanese Government launched a comprehensive research project "MAC 21" for development of membrane technology and its application to public water supply. The project was conducted by the Water Purification Process Association (WPPA), under the supervision of the Institute of Public Health. By the research project from FY 1991 to FY 1993, we confirmed that microfiltration (MF)/ultrafiltration (UF) technology was applicable to water purification and MF/UF was a effective method for the removal of such contaminants as particulate matter and coliforms. The Guideline Committee organized under the Technical Committee prepared a the guidelines on application of membrane system to small-scale public water supplies, based on the results as written above. The guidelines has been published in Dec., 1994 by WPPA.4 by WPPA.

  • One of the problems associated with the current system of land development projects implemented by the public sector in Korea is that various service facilities are not ready in time for the occupation of residential dwelling. A major cause of the problem is the lack of financial arrangements which would smooth the cash-flow of the suppliers of the facilities during the project period. In this paper we present two schemes which will contribute to the optimal provision of service facilities by easing the financial constraint facing the land developers and suppliers of the facilities. The first scheme involves channeling a fraction of profits from a land development project and of the proceeds of mandatory sales of Type II National Housing Bonds as a loan to the suppliers of the service facilities. The second scheme considers the participation of the private sector in the project as a member of a consortium comprising the Korea Land development Corporation, the National Housing Fund, and private developers. It is proved that each scheme is superior to the current system. as well as entailing a very small cost.

  • Previously, we have identified 14 putative downstream target genes of Hoxc8 homeoprotein in F9 murine embryonic teratocarcinoma cells through proteomics analysis. Among those, we tested a possibility of a DNA-k type molecular chaperone, Grp78, as a direct downstream target of Hoxc8, by cloning a 2.4 kb upstream region of murine Grp78 into a reporter plasmid and by testing if Hoxc8 can regulate its expression. We observed that Hoxc8 proteins could transactivate the reporter gene, which was affected by small interference RNAs (siRNAs) against to Hoxc8, suggesting that Grp78 is a novel downstream target of Hoxc8 in vivo.

  • Integrating multi-trade works system helps to reduce to minimize the conflict of subcontract business and improve communication to increase productivity of construction. However it takes such a big risk if subcontract of integrating multi-trade works went bankrupt during the project so some of construction companies executed to only small project and it's not sufficient to adopt overall project. This paper suggested the improvement scheme of work classification integrating multi-trade works, which takes a consideration into work zoning in order to apply current work situation.
