공정거래위원회(위원장 권오승)는 최근 하도급법 위반사업자에 대한 과징금 부과시 과징금 부과여부 결정 및 과징금액 산정을 위한 세부 기준을 마련하고 지난 8월 22일 하도급법 위반사업자에 대한 과징금 부과기준에 관한 고시를 제정한데 이어 지난 8월 30일부터 시행에 들어갔다. 공정위는 과징금 부과를 위해 종전에는 위원회 사무준칙인 지침을 운용하였으나, 이번 고시 제정을 통해 과징금 부과의 예측가능성, 객관성 및 투명성을 제고하였다. 고시에 따르면 원사업자의 위법행위를 신고한 중소 하도급업체에 거래단절 등 불이익을 주는 보복행위를 하거나 하도급대금·어음할인료·지연이자 등을 지급한 후 이를 회수 또는 납품대금에서 공제하는 탈법행위 등 악성 위법행위에 대해서는 과징금을 부과하기로 했다. 또 위반사업자가 하도급거래시장에서 영향력이 큰 대기업자 이거나 과거 위반전력이 많은 경우로서 부당 하도급대금 결정, 부당감액 등 중대하거나 파급효과가 큰 위반행위를 했을 때도 과징금을 부과하기로 했다. 공정위가 하도급법 위반사업자에 대한 과징금 부과여부의 결정기준과 과징금액 산정방식을 보다 구체화하여 시행함으로써, 법위반의 정도에 상응하는 제재로 인하여 법집행의 실효성이 강화되어 재발방지 효과가 클 것으로 기대된다. 아울러 과징금 부과의 객관성과 투명성을 높이는 한편, 예측가능성을 높임에 따라 대기업 등 원사업자의 자율적인 하도급법 준수 의식을 제고하여 법위반을 사전에 방지함으로써 중소기업의 피해를 예방하는데 크게 기여할 것으로 보여진다.

정보화의 발전은 모든 산업의 시스템화 및 자동화를 이끌어가는 원동력으로 국가 산업에 융복합되어 시너지효과를 발현하고 있다. 이러한 정보화의 일환으로 건축공사의 50~60%차지하는 건설자재의 정보화는 필수불가결한 요소이다. 특히 건설자재의 가격정보는 자재선정을 위한 결정적인 요소임에도 불구하고 현장여건에 맞는 정확한 가격정보를 제공하기에 어려움이 있는 것으로 조사되었다. 따라서 자재선정 의사결정자가 건설자재의 다양한 정보항목을 검색하고, 활용할 수 있는 건설자재에 대한 정보제공 시스템의 필요성과 온라인을 통해 현장여건에 맞는 가격정보 제공의 필요성이 대두 되었다. 이에 본 논문에서는 자재선정 의사결정자들이 온라인 자재정보시스템을 통해 검색한 자재의 현장여건에 맞는 가격정보를 빠르게 획득할 수 있도록 지원하는 견적지원 기능을 제시한다. 이 시스템은 관계데이터베이스를 통해 정보를 저장하고 활용한다. 본 연구는 건설분야 종사자들에게 건설자재선정을 위한 지원 도구로써 활용될 것이며, 이는 최적자재선정을 통한 건축물의 품질을 개선하는데 기여할 수 있을 것이다.

Recent years, the construction projects of a world-wide have changed toward integrated evaluation considering all environmental and economic aspect for ecological construction.. The object of this study is to suggest the method and system for integrated analysis VE/LCC and LCA. In order to integrate and analyze environmental and economic aspects of alternative design elements, decision maker should handle simultaneously much information such as cost, document and drawing. This study presents applicative methods of WBS for integrated management of these information. Also, this study presents a decision support system that can manage DB easily by using VE, LCC and LCA analysis module separately.

Technology assessment is one of the most challenging decision making areas that companies face nowadays. According to increase the importance of technology selection, it has been a main issue for the decision makers whether an appropriate technology selection will be successful or not. Therefore, in this study, a technology assessment model using BSC and ANP method was proposed. The technology assessment model consist of three phase. In first phase, various factors, that have an influence on technology assessment, were taken into consideration. Based on the extracted BSC process, the strategies and critical success factors and performance measures were extracted for selecting the technology. And in second phase, the ANP method used to integrate opinions of experts' and evaluate technology alternatives controls tangible and intangible criteria, allows for more complex inter-relationship among decision levels and deals with ambiguity involved in the assessment process. In the lase phase, according to the result of before phase, decision makers select the appropriate technology. Furthermore, the proposed model was applied in the public service for validating the feasibility of the assessment model. The criteria and proposed performance measures informs the method and focus areas for developing the technology. Furthermore, the assessment model can be applied to the other area, and give the objectivity and rationality.

This paper is to build a spatial decision support system designed to solve problems relevant to the decision-making for retail center locations. For construction of the system this paper discusses the primary procedures of spatial modeling and issues of data, which are required for integrating spatial interaction models to GIS having capability of managing, analyzing and visualizing spatial data sets. Lexington, Kentucky, is selected as a case study to implement the spatial decision support system based on the spatial modeling module. This system for retail center locations is useful of estimating the catchment areas more accurately and analyzing resultant flow patterns. And this system can make spatial analysis efficiently for what-if scenarios such as an intended retail center or changing demand. The benefits of adopting this system allow the decision makers to plan the investment strategies and search for stable market structure.

Streams and rivers are among the most fascinating and complex ecosystems on Earth. Recently, many plans of ecological streams are developed and performed in several regions. In spite of obtaining of instream water is most important problem to composite an ecological stream, assessment methods for instream water are too various to estimate an optimal result. In this study, we developed decision support system so that decision-maker may can be supported decision making for composite an ecological stream with connecting the satisfaction of residents in stream. Decision support system is composed of hydraulic, water quality, eco-river simulation model and can show optimal instream flow assessment and water quality improvement.

This study applied and compared Poisson model, negative binomial model, zero inflated Poisson model, and zero inflated negative binomial model to estimate determinants of employed labour quantity. To estimate each of models, this study used fisheries census data which were obtained at microdata integrated service running by Statistics Korea. The study selected zero inflated negative binomial model according to the Vuong test and Likelihood-ratio test. In addition, the study estimated fishing village's practical changes on employed labour quantity as analyzing changes from 2010 to 2015. The results showed that the household with fishing vessels and high selling price had a significant effect on decrease of the labour quantities. Meanwhile, the longer work experience of the household, the more significant the increase in the labour quantities. In conclusion, this study presented that capitalized fishing household and the acceleration of aging had a significant impact on the change in the labour quantities.

Islands are supplied with power from diesel generation or from photovoltaic power generation, and problems with offshore environmental impacts (age deterioration, salt pollution), environmental pollution (exhaust gas, noise, dust) and power generation costs (installation, maintenance) have increasingly emerged. In 2016, the cost recovery rate was only 27%, and deficits reached 73% on 65 islands managed by KEPCO. In terms of deficits, the costs incurred in the power generation sector accounted for 91%, with the ratio of fixed costs at about 60%. Analysis suggests that operating costs can be reduced with an optimal power supply system that improves power generation efficiency and makes operating systems more efficient. Therefore, it is possible to simplify fuel transportation and facility maintenance, because one island integrates the power plants of remote islands, and offshore cable is used to supply power to the other islands. From the economic evaluations in this paper, an algorithm deciding offshore cable layout validity for an integrated power supply between adjacent islands is presented. Simulation results based on the proposed algorithm confirmed that an integrated power supply is economical for existing stand-alone operations on islands having diesel generation, low peak power, and near distances.

In the case of the impacted teeth, the clinician has to consider development of tooth, site of impaction, eruption path, and cooperation of patient. If there are genetic or general factors to effect the eruption of tooth, the clinician treats these first and then takes the early treatment for eruption guidance. If there are physical factors to intercept eruption, the clinician put them off first. However, if there are no factors to effect eruption of tooth and enough space for eruption, the clinician can consider extraction of deciduous teeth, forced eruption and surgical reposition. In case of surgical repositioning, proper time for root development, proper socket formation, and minimal trauma are important for success. This case presents displaced impacted maxillary central incisor with dilacerated root. The development of root is Nolla's stage 7, and the tooth was treated by surgical repositioning. We can observe no root resorption and good healing pattern.
