This paper aims to analyze the characteristics of BTL, and to propose the effective models connecting BTL and project finance, through the analysis of current state and case study of BTL. The main results of this study are as follows. Firstly, BTL business have been increasing fast, and most of projects are middle size projects below 100 billion Won. Nextly, key suggestions for improving BTL business model are analyzed, which are, first, risk allocation between public and private interests, second, improvement of method for selecting private investment consortium, and third, alleviation of long-term burden of local finance. Finally, effective models for connecting BTL and project finance, which are, first, model for using asset backed securities, second, model for dividing project corporations into construction corporation and operation corporation, and third, model for risk allocation between public and private interests.

The BTL and CM are main issues in Korea construction industry lately. The BTL applying CM is sufficient to have interest in terms of combination of BTL and CM. OO Cultural and Welfare Complex Town construction was the first cultural and welfare facility with the BTL applying CM. Because application of CM to the BTL project is at the early stage, there are many problems under the progress such as administration procedure from misunderstanding of the BTL and lack of communication between supporting Dept. and management Dept. This article focuses on those problems and advantages of CM services including negotiation, schedule management and cost management for the better CM service in the BTL project in the future.

Since 'Private Investment Act for Social Infrastructure Facilities' were changed in January 2005, BTL projects have been activated in the market. Nevertheless, several problems have been indicated as to the BTL system. Most of these problems are about the choice and scale of the target facilities and the reasonable rate of return allowed to the private investors, which are directly related to the VFM (Value for Money) analysis for the BTL projects. This study discusses the concepts and the methodologies of the VFM analysis, reminds its importance by investigating current problems of the BTL system concerned with the analysis, and suggests useful implications and alternatives through the case studies on the four ongoing BTL projects for the educational facilities.

As a new form of the public procurement method, that is BTL(Build-Transfer-Lease) was introduced in 2005, it has consequently created a new form of emerging business, so called BTL Project Management firms. As a key participant of BTL projects, PM firms play an important role in securing the projects. But due to the short history of BTL, the identity of BTL PM firms has not been widely understood. The objective of this paper is to investigate major characteristics of BLT PM firms for better understanding of the emerging business.

Koran Government introduced BTL(Build-Transfer-Lease) to provide convenience through early supplying infrastructure and plans to invest 8,315million dollar to 84 projects of 15 BTL type involving official residence and railroad. But some of construction company hates to invest BTL projects because of its low earning rate. In addition if we correctively apply project which partly has profitability to BTL, the earnning rate declines more seriously. So this paper presents BTL+BTO model which operates BTL in the non-profitable parts to improve convenience of users and BTO in the profitable parts to improve earning rate. BTL+BTO model based on operate period was presented and its suitability was confirmed by applting 00 region official residence project.

After reformation of 'the law of private investment on social infrastructure' on January 2005, BTL of educational facilities can improve the education circumstance at early stage, however there are trial and error, problems of execution as well. The key of this problem is not only related to whether BTL project is more reasonable, but it also leads to the proper performance of eligibility analysis on BTL. Therefore, it lead to the proper carryout of eligibility analysis on BTL. In order to promote effective BTL project of educational facilities, this study analyzes problems of existing model and creates the evaluation model for solving this problem. In this study, the evaluation model of investment on BTL has more quick ,accuracy and useful effect than previous one, if it is applied on eligibility stage. Moreover, this method could be applied to public building, SOC facilities effectively based on being modified as each characteristics of structure suitably.

After the revision of Private Investment Law in January 2005, BTL is introduced to expand the social infrastructures as a major business procedure. Especially, the size of the public educational infrastructure ordered by each city education office is increased by 45% compared to last year, so it is major in BTL Project. However, in the process of practicing BTL Project by now, there are a lot of problems specially in the public educational infrastructure. As a result, this study gives the solutions in the process of BTL Project, the CM models to support the Education Office${\square}{\square}$job and the suggestions for the working scope of the participating construction companies.

BTL business-related systems were developed by the Ministry of Education, Korea Development Institute, Korea Education Development Institute. These systems were effectively support to BTL projects schools that expanding in size. However, compatibility of information is difficult between systems that specific information system developed for the purpose of functional redundancy. In this study, operational readiness, facility management, operations and the assessment phase are divided in the BTL school projects process. And the business functions were analyzed in the related systems. In addition, we are contributed to improve standards and the school BTL business processes to improve the reliability of the process.

The objective of this research is to develop an assesment system for BTL Project. A new method for the prediction of construction and maintenance cost in the educational facilities has been considered and under development by the authors. This paper explains the current BTL assesment method used by most local district office of education and lists its potential problems. Main conceptual modules in the new Assesment System are shown in this paper. Also, viable results of each module are discussed in this paper.

In view of stringent environment regulations to control the emission of green house gases and also depleting fossil fuel reserves, it is high quality desirable to develop alternative technologies to produce high quality fuels. To this end Biomass to Liquid (BTL) technology has received much attention in recent years. BTL process generally consists of gasification of biomass to produce bio-syngas, cleaning and control of $H_{2}/CO$ mole ratio of bio-syngas and Fischer-Tropsch synthesis & upgrading systems. Choren, Germany has first developed the commercial BTL process using unique gasification system i.e., Carbo-V. A new technology to remove tars and BTX has been developed by ECN in Netherlands employing a gasification system combined with OLGA technology. Several other countries including USA and Japan are showing great interest in BTL technology. Thus in view of our national energy security and also the environmental regulations, it is essential to develop alternative technologies like BTL in order to meet the increasing demand of energy though our insufficient biomass resources. In this paper we present an overview and development status of BTL-diesel technology.
