현행 민영화정책이 공기업의 효율성제고를 최우선 목표로 설정한 것은 타당한 선택이었음에도 불구하고, 경제력집중 심화에 대한 우려와 주식시장의 제약 등을 이유로 민영화정책은 그 추진실적이 부진하고 향후 지속 여부가 불투명한 것이 현실이다. 본(本) 논문(論文)은 우리나라 공기업민영화를 둘러싼 논쟁의 핵심인 경제력집중(經齊力集中), 경쟁도입(競爭導入), 주식시장여건(株式市場與件) 등이 공기업민영화와 관련하여 어떻게 이해되어야 할 것이며, 바람직한 정책대응(政策對應)은 무엇인지를 논의하고 있다. 재산권이론(財産權理論)을 동원하여 주인(主人) 있는 경영(經營)의 의미를 재해석할 때, 기업지배(企業支配) 통제구조(統制構造)의 정착이 요원한 우리 현실에서 민영화가 기업효율을 제고하려면 민간대주주(民間大株主)의 지배(支配)를 인정하는 방식이 최선책(最善策)이며, 소유가 분산되고 전문경영체제(專門經營體制)를 도입하는 민영화방식은 지배구조(支配構造)의 실패가능성(失敗可能性) 때문에 차선책(次善策)이라고 평가된다. 그러나 효율성 차원의 최선책은 경제력집중이라는 국민경제적 비용을 초래하므로, 정부로서는 경제력 집중이라는 비용(費用)과 효율성이라는 편익(便益)을 조화시키는 방안을 모색할 수밖에 없다. 이 경우 정부가 고려할 보완책(補完策)으로는 감자후(減資後) 민영화(民營化)와 분할민영화(分割民營化)가 있다. 한편 자연독점의 특성이 뚜렷한 일부 네트워크사업분야를 제외하면, 민영화시 경쟁도입(競爭導入)은 기업효율성과 국민경제의 배분효율성을 제고하므로 정부로서는 당연한 선택일 것이다. 경쟁은 공기업의 인수자격규제에 있어서도 새로운 기준을 제시하는데, 민영화를 정부(政府)와 민간(民間)사이의 M&A로 이해하고 경쟁제한적(競爭制限的) 기업결합(企業結合)을 규제하는 공정거래법(公正去來法)의 정신(精神)이 인수자격규제기준이 되어야 하며, 업종전문화(業種專門化) 발상(發想)에 근거한 인수자격규제는 득보(得)다 실(失)이 클 것이다. 아직도 자생적 성장기반이 취약한 주식시장의 제약에 따라 민영화일정의 탄력적인 조정은 불가피하지만, 정부는 상장(上場)의 필요성(必要性)을 재검토하고, 매각(賣却)의 우선순위(優先順位)를 조정하며, 무엇보다도 양질(良質)의 주식(柱式) 공급(供給)이 수요(需要)를 창출하는 메커니즘을 개발해야한다. 이와 함께 본(本) 논문(論文)은 현행 추진체계(推進體系)에 내재된 민영화의 지연가능성이 심각한 문제임을 지적하였고, 대규모 공기업의 민영화가 대기업(大企業)의 새로운 전형(典型)을 창출하여 한국자본주의(韓國資本主義)의 건전한 발전을 앞당기는 역사적 기회라는 점을 강조하고 있다. 마지막으로 재벌인수가 가능한 경우와 규제되어야 할 각각의 경우에 대하여 민영화정책(民營化政策)의 '체크리스트'를 제시하고 있다.

나트륨(소금)의 경우 식품에 관능적 특성 부여 및 가공과정에 필수적인 물질이나 과다 섭취의 경우 고혈압 등 심혈관계 질환을 발생을 증가시키는 등 사회적인 문제가 되고 있다. 특히 한국인의 경우 장류, 젓갈 및 김치 등의 식품문화가 발달되어 WHO의 권장섭취량의 2배 이상 섭취하고 있는 실정이다. 나트륨 저감화의 경우 국민복지 향상, 의료비용 절감 및 사회적 편익비용 발생 등의 이유로 국가적 차원에서 나트륨 절감이 시급한 상황이다. 현재 식품의약품안전처 및 보건복지부 등에서 나트륨 저감화를 위한 다양한 정책 등을 추진하고 있다. 또한 세계적으로 무기염류 대체소금, 염미증진제 및 향미개선제 등의 개발 노력이 활발히 이루어지고 있는 상황이다. 그러나 낮은 관능적 특성 및 무기염류의 과량 사용에 관한 부작용 등으로 인하여 급증하는 소금대체 및 보완제 시장수요에 미치지 못하는 실정이다. 따라서 저염화 및 관능적으로 우수한 소금 대체소재 및 염미 증강물질 개발이 요구된다. 염미 및 지미상승 식물성 발효 조성물(SAP)의 경우 분리대두단백 등의 식물성 원료와 전통 장류의 제조원리를 응용한 염미증진제 또는 향미개선제이다. 관능적 특성을 조사한 결과 기존 사용되는 저염 소재에 비하여 염미 등의 관능적 특성이 우수하여 염미 및 관능적 특성 증진 소재로 활용 가능성이 높았으며 무기염류의 단점인 낮은 관능적 특성 및 무기염류에 의한 부작용 등의 우려가 없는 소재이다. 향후 염미 및 지미 상승 식물성 발효 조성물(SAP) 등의 활용방안 개발 및 적용분야 확대 등으로 국내 저염 식품 산업의 전반적 발전에 도움이 될 것으로 생각된다.

Both of district heating(DH) system and natural gas(NG) supply system have benefits in clean energy supply and having energy efficiency and savings. The issue of duplicate investment and supply requirement of only for cook occur several conflicts such as destruction of the Beneficiary Pays Principle and Cross Subsidization, etc. Under the circumstance, the purposes of this research are to consider several issues of cross subsidization in NG and DH industries and to present the following alternatives for resolving related problems. First of all, a charging mechanism in the energy cost must be improved so as to maintain the positive relation between cost and benefit. That is, the beneficiary-pay principle must be strictly applied. Secondly, the extended supply of DH through HOB(Heat Only Boiler) must be strictly limited. Finally, we need to improve efficiency for the benefit of market participants.

The accident risks in the marine environment are increasing because of the tendency to build faster and larger ships. To secure ship safety, risk-based ship design (RBSD) was recently suggested based on a formal safety assessment (FSA). In the process of RBSD, a ship designer decides which risk reduction option is most cost-effective in the design stage using a cost-benefit analysis (CBA). There are three dimensions of risk in this CBA: fatality, environment, and asset. In this paper, we present an approach to estimate the environmental costs based on the size of an oil tanker involved in an accident using a neural network. An appropriate neural network model is suggested for the estimation,and the neural network is trained using IOPCF data. Finally,the learned neural network is compared with the cost regression equation by IMO MEPC 62/WP.13 (2011).

The importance of environmental resources has been recognized over the world after Rio declaration(1992). so it is moved to monetarize environmental resources. The studies on the evaluation of nonmarket goods began also in the early 1990 in Korea. In practice the preliminary feasibility studies(PFS) are carried out since 1999 in case of major public investments projects. In PFS the Benefit-Cost analysis is practically used. which is considering the evaluation of environmental resources. But the methods for the evaluation have not been fixed up. In this study It is introduced to the theory and major methods for the evaluation of environmental resources. In the theory the evaluation is handled in aspect of demand function and supply function. The optimum level can be extracted from the two functions. In the method. travel cost method(TCM), hedonic price method(HPM) and contingent valuation method(CVM) are introduced according to the market structures.

Solid waste collection service is viewed as one of the most important public services in urban area. The purpose of this study is to apply the GIS based regional partitioning and arc routing methods for solid waste collection districting and vehicle routing-scheduling in order to provide waste collection service more efficiently. In this study, solid waste deposit sites are derived from the centroid of each building and the amount of solid waste is deduced based on the number of households and establishments. The regional partitioning procedure is performed based on waste collection zones which are constructed from waste deposit sites. The result of this study shows that solid waste collection districts which are delineated by regional partitioning method are able to increase efficiencies and cut costs in performing solid waste collection services. Also the output of vehicle-scheduling from the analysis of arc routing may provide more efficiently and quickly manage the scheduling of the residential solid waste collection routes, reducing costs with minimal deadheading costs. Therefore, the application of GIS based on regional partitioning and arc routing methods would be very useful to construct a solid waste management system by supplying the important and flexible informations for solid waste collection districts and vehicle routing-scheduling for waste collection.

Reasonable methods are needed to predict the noise level of new/existing roads and to select means of noise reduction. In this study, the noise reduction effects of both soundproof walls and quiet pavements were predicted. The noise reduction effects of quiet pavements were predicted by measurement data obtained using the CPX method in test pavements. The noise reduction effect was predicted by KHTN program when applied to soundproof walls and quiet pavement. As a result, the predicted noise level was similar to the measured one. The design method was suggested by an economic analysis using noise benefit of predicted noise reduction. The research suggests that the optimum alternative has to be determined using noise prediction method and life-cycle cost analysis.

The system of high-speed and conventional railway vehicles is diversified, and significant technological development in performance has been achieved. This study analyzed the modal change characteristics; furthermore, it estimated the value of travel time by improving the travel time and cost for the passenger's perception of railway. In this study, we formulate a mode choice model for passengers and compare it with the mixed logit model which reflects individual taste variation. In addition, the validity of the analysis is presented through an estimation the value of travel time using the derived model. For this purpose, a stated preference survey was conducted with 510 people using public transportation. The benefits of time-saving can be accurately determined by estimating the value of time spent on the railway. Appropriate fares for public transportation can also be estimated.

This research carried out an analysis on input cost and leakage reduction effect by leakage reduction method, focusing on the project for establishing an optimal water pipe network management system in the Taebaek region, which has been executed annually since 2009. Based on the result, optimal cost-benefit analysis models for water distribution network rehabilitation project were developed using DEA(data envelopment analysis) and multiple regression analysis, which have been widely utilized for efficiency analysis in public and other projects. DEA and multiple regression analysis were carried out by applying 4 analytical methods involving different ratios and costs. The result showed that the models involving the analytical methods 2 and 4 were of low significance (which therefore were excluded), and only the models involving the analytical methods 1 and 3 were suitable. From the result it was judged that the leakage management method to be executed with the highest priority for the improvement of revenue water ratio was installation of pressure reduction valve, followed by replacement of water distribution pipe, replacement of water supply pipe, and then leakage detection and repair; and that the execution of leakage management methods in this order would be most economical. In addition, replacement of water meter was also shown to be necessary in case there were a large number of defective water meters.
