최근 통신 및 컴퓨터 기술이 급속하게 발달되고 전기설비의 계측 및 보호계전기의 디지털화가 본격적으로 진행됨에 따라 수배전 설비분야에서도 고 신뢰도 및 고품질의 전력을 공급하기 위한 많은 기술들이 개발되고 있다 그에 따라 기존 아날로그 방식의 유도형 수배전반의 단점을 보완하기 위한 디지털 보호계전기 기반의 전자화 및 일체형 수배전반의 수요가 점차 증가하고 있다. 본 논문에서는 수배전반의 구성과 부하설비에 관한 정보를 기반으로 실비 및 부하운영상태의 이상 유무를 판단하고 대처할 수 있는 지능 시스템 구현의 기초가 되는 지식기반 추론기법의 접근방법을 논하고자 한다.

This study aimed to quantify antibiotic consumption and expenditures for acute upper respiratory tract infections (URIs) (J00-J06) in outpatients from 2009 to 2011. We used WHO ATC classification and DDDs in measuring antibiotic consumption. National Health Insurance and Medical Aid claims data were analyzed. Antibiotic consumption has decreased from 4.44 DDD/1,000inhabitants/day in 2009, to 4.43 in 2010 and 3.74 in 2011. The estimated expenditures were 8,206 won/1,000inhabitants/day in 2009, 8,379 in 2010, and 7,004 in 2011. Clinics accounted for 89.8% and 86.0% of antibiotic consumption and expenditures respectively for the acute URIs in 2011. We need to monitor antibiotic consumption consistently, and promote judicious antibiotic use.

1990년 9월 프렌치 엔더슨(현 남가주대학 유전자치료센터 소장)과 2명의 동료들이 미 연방정부의 승인을 받고 처음으로 유전자를 이용하여 중증 종합면역결핍증(SCID)을 앓고 있던 아샨티 데실비양을 치료한 이래 유전자치료에 대한 관심은 전세계적으로 번져 나가 현재 2천5백명 이상의 환자들이 이런 요법의 임상실험을 받고 있다. 우리나라에서도 1995년 서울대병원을 시작으로 1996년에는 중앙대병원과 삼성서울병원에서 말기 암환자를 대상으로 유전자치료 임상시험을 하고 있다. 그런데 열성적인 일부 연구자들과 업계대표들 그리고 매체들의 유전자치료의 '장미빛 미래'를 지나치게 강조한 나머지 일반인에게 유전자치료가 이미 광범위한 응용단계로 들어갈 정도로 발전한 것 같은 인상을 주고 있다. 그러나 전세계를 통틀어 유전자치료를 받거나 받고 있는 환자중에서 결정적으로 완쾌된 환자는 아직도 거의 없다는 것이 오늘의 현실이다. 유전자치료의 현황과 그 앞날을 알아본다.

As buildings take on more advanced features, mechanical facilities of buildings are accounting for increasingly greater significance in building construction projects. However, mechanical facility designers are forced to be content with design service fees that do not properly compensate their excessive workload, with lowest-bid-first tendering practices compounding their economic woes. In relation to this, this Study aims to offer suggestions for better standards for compensation of design service for mechanical facilities of buildings, highlighting five key suggestions in consideration of relatively small size of work and unmatched long duration of work.

현재까지 변전소에 구축되어있는 변전소 자동화 시스템은 기존 설비를 바탕으로 지능형 장비(IED)를 추가한, 전력설비 자체의 인텔리전트화가 아닌 2차 설비(제어, 보호, 감시 장치)의 인텔리전트화를 지향하고 있었다. 그러나 본 실증변전소는 CT, PT와 같은 1차 설비에서부터 상위 시스템까지 전체 전력실비를 Intelligent화하였으며, Hardwiring되어 있는 시스템을 모두 통신과 S/W로 처리하였으며, 국내 최초로 Merging Unit을 개발, 적용하여 디지털 계전기를 검증하였다. 또한 향상된 예방진단 시스템 및 보안방재 시스템을 도입하여 변전소종합자동화 시스템을 구축하였다.

The standard for the cost calculation in the field of domestic construction engineering can be largely divided into the construction cost ratio method and the actual cost addition method. However, the standard for calculating the cost of the construction cost ratio method is a trend to switch to the actual cost addition method due to limitations such as not reflecting the characteristics of the construction. Therefore, this study aims to derive implications by investigating and analyzing examples of cost standards in the field of overseas construction engineering, such as the United States, and deriving directions for improvement in domestic cost standards in the future.

For the sustainable development of the domestic construction project management field, each CM company should try to diversify in terms of service contract types and scope of work while having internationally competitive technical and service capabilities as follows. First, from the initiation of the service to the completion, the CMr should be able to establish and execute a plan to create specific outcomes. Second, CMr must have the capability to produce weekly or monthly cost, schedule, risk, and scope management reports. In addition, it should be possible to apply the cost plus sliding fee method or to systematically and continuously accumulate and process data generated during the construction process.

The Korean Construction Industry significantly contributed to the Korean economic development not only by preparing the domestic infrastructure but also by successfully conducting various international projects. However, major incidents such as the collapse of Sung-Su Bridge and Sam-Pung Department Store along with stagnation of Korean Economy have raised questions about underlying systematic problems of the Korean Construction Industry. As a solution to resurrect the Korean Construction Industry, the Construction Management (CM) system introduced in late 1990's and increasingly utilized as an innovative delivery system. Despite of the fast growth of CM, the performance of CM has not been up to the hype and low CM fee has been identified as one of the main reasons of unsatisfactory CM performance. Therefore, this research attempted to propose ways of improving 'CM Fee Guidelines' published by Korean Ministry of Construction and Transportation by conducting a benchmarking study on Global Standards of estimating CM Fee. International organizations benchmarked in this research include CMAA, ASCE, DOL, DOE, etc. Various investigation and analysis revealed that Korean 'CM Fee Guidelines' need to significantly modified comparing to Global Standards. This research also tried to prepare recommendations to improve the CM deliver system focusing on the 'Method of CM Fee Estimation' and Selection of a CM firm as an owner's agent.

This study is as to payment improvement method of additional incidental cost to be occurred upon extension of public construction time. According to the result of analysis about the cause of non-payment of additional incidental cost of construction time extension through site examples, it was found that difficulties exist in disputes & proofing over the scope of actual cost recognition, and in this regard the result of experts opinion indicated that a construction extension pre-agreement system can be executed which agrees the scope of recognition of additional incidental cost of construction time extension once the statistical standard is clear and accurate. Accordingly, in this study, by totalling multiple sites data, calculations were implemented in terms of type of construction projects, amount of constructions, period of constructions. According to the result of calculation, the element of type of construction project and construction period appears to have none direct effect to the occurrence of additional cost of construction time extension, but direct relationship was indicated related to the contract amount element. In view of above, in this study a standard additional incidental cost of construction time extension was proposed, and presented a system improvement plan to implement the construction extension pre-agreement system.

In the construction project, the design field has a crucial effect on the success or failure of the final product, and it is becoming more important as a core area of national industrial development because it creates high value added by technology. In addition, since the design work is carried out based on professional technical personnel, in order to secure the quality and competitiveness of the design, it is necessary to continuously input the excellent manpower and develop the technology, and above all, the appropriate design cost must be ensured. However, as a result of reviewing the current status of the design cost criterion in Korea, problems such as mixed cost calculation method, inaccuracy of construction cost ratio method, and inactivation of cost plus fixed fee method were analyzed. Therefore, it is difficult to calculate the fair value reflecting the characteristics of the project when calculating the construction design price. Therefore, the price criterion should be improved so that the fair value of the design can be determined according to the contents of the project, By analyzing the correlation and multiple regression analysis of the projects and price information of the completed road construction design, the factors influencing the design price and the level of influence were analyzed.
