This study has examined the allocation of risk in Korea's Private Provided Infrastructure (PPI) with the following contents: (1) Developing a quantitative risk allocation model for Korea's PPI and (2) examining the implication of changes in the minimum revenue guarantees (MRG) clause of government legislation using the developed empirical model. The model of this study adopts and extends H. Yamaguchi's model developed in 2002. To investigate Korea's actual risk allocation deals, the author incorporated the MRG framework. The payment related to the MRG is indeterminable. Hence, the average MRG rate was calculated using probabilistic risk analysis.The risk allocation model is applied to the two cases to validate the model and evaluate the project's VFM(Value for Money). As the revenue guarantee rate is lowered, the government subsidies are increased. This in turn worsens VFM. The same relationship is true when the revenue guarantee period is shortened. 본 연구는 한국 민간투자사업의 위험배분문제와 화폐적 투자가치를 측정하는 모형을 구축하고 이를 통해 정부의 최소운영수입 보장률 및 보장기간의 변화에 따른 화폐적 투자가치의 변화를 관찰하였다. 모형은 H.Yamaguchi의 위험배분모형(2002)을 기반으로 한국의 민간투자사업 현실에 맞게 2기간 모형으로 변환하고 최소운영수입보장 제도를 포함하도록 수정하였다. 분석결과 정부의 최소운영수입 보장률 및 보장기간이 축소됨에 따라 동일한 수익률을 가정하는 경우 국고보조금이 증가하게 됨으로써 민간투자사업의 화폐적 투자가치는 하락함을 보여주었다.

This study was designed to isolate the strains of the tonsillar surface and core and study the beta-lactamase activity of them. 103 pediatric patients who were performed tonsillectomy and adenoidectomy from September 1990 to February 1991 at Department of Otolaryngology of Chung Ang University Hospital were divided into the recurrent tonsillitis group and the simple enlarged tonsil group in this study. The results were as follows; 1) The numbers of patients in recurrent tonsillitis group were 63 cases and those in simple enlarged tonsil group were 40 cases. 2) In the recurrent tonsillitis group, alpha-hemolytic streptococcus (60 cases), Neisseria species (56 cases) and Staphylococcus aureus (7 cases) were cultured from the surface of tonsil, Alpha-hemolytic streptococcus (58 cases), Neiserria species (48 cases) and Staphylococcus aureus (9 cases) were cultured from the core of tonsil. 3) In simple enlarged tonsil group, alpha-hemolytic streptococcus (39 cases), Neisseria species (37 cases) and Staphylococcus aureus (4 cases) were cultured from the surface of tonsil. Alpha-hemolytic streptococcus (35 cases), Neisseria species (30 cases) and Staphylococcus aureus 11cases) were cultured form the core of tonsil. 4) The numbers of patients from which beta-lactamase-producing bacteria were detected were 27 cases (26.21%) and these organisms were sensitive to oxacillin, clindamycin, chloramphenicol, gentamicin, and cephalosporin.

The purpose of this study is to introduce LEM(Location Efficiency Mortgage) in U.S. and envision the affordable housing supply in the center of mass transit. Urban sprawl and increasing car-use have made commuting laborers set their financial condition back and have deteriorated city’s air condition. LEM is invented for the purpose of overcoming the urban sprawl problem and enhancing the purchasing power of low income house demander simultaneously. Owing to co-work of many institutes and authorities concerned, that is, The Natural Resources Defense Council, The Center for Neighborhood Technology, and The Surface Transportation Policy Project, the scheme of LEM has been made. Transit user who lives in location efficiency Area can borrow more money as much as transportation savings. This paper compares LEM with the various housing policies, such as Bogeumjari housing, SHIFT, and LIHTC. Also the limitations and controversy of LEM is described and the prospect and tasks of application LEM to Korean housing market is suggested.
