  • Areas developed through land reclamation projects have huge economic advantages in terms of supplying lands that can be used for farmlands, urban areas and etc., however have relatively small areas of grasslands and densely located buildings compared to inland cities. Hence, an urban heat island is occurring in these areas due to this characteristic, and in particular, the urban heat island in Cheongna International City is getting serious. In this study, the urban heat island in Cheongna International City was evaluated and analyzed by classified into the three periods after the reclamation project: farmland(2001-2008), development(2009-2013) and artificial grassland(2014-2020). The land cover map and Landsat time-series imagery were utilized for measuring the differences of the land surface temperatures between the urbanized areas and the grassland/forest areas in Cheongna International City. The statistical results showed that the differences in the land surface temperature between these areas were calculated to be at most 0℃ during the period of farmland, at most 3.60℃ during the period of development, and at most 2.51℃ during the period of grassland. This study proved that the urban heat island phenomenon increased when the urbanized areas increased, and the urban heat island phenomenon decreased when the artificial grassland areas increased in Cheongna International City where the reclamation project was carried out. The statistical results derived through this research can be used as the reference data for identifying the urban heat island problem in urban planning and establishing the reduction plan.

  • The size of the construction industry is increasing, and its impact on the entire national industry is also significant. However, construction cost increases, construction period delays, safety accidents, and quality problems occur during the construction process. This paper analyzed the construction cost, construction period, and change order performance for civil infrastructures for which post evaluation was performed. The analysis was conducted by dividing civil engineering facilities by type, construction nature, construction cost, contract nature, and delivery method. Planned and actual construction cost and period were compared during the planning, design, and construction process of civil engineering facilities. There is a possibility of input errors in project performance data, this paper proposes to the post-evaluation center should perform post-evaluation. Also, post-evaluation implementation guidelines for change orders should be revised. Additionally, further analysis of each facility was proposed through continuous data collection.

  • 4대강 살리기사업은 역대 정부가 추진하는 단일명칭의 사업 중에서 가장 규모가 큰 사업이다. 전국 토의 75%에 해당되는 4대강 유역 전반에 걸쳐 추진하는 사업인 만큼 전국 단위에서 추진하는 사업으로 볼 수 있다. 동시에 22.2조원에 달하는 사업비를 투입하여 3년내에 완료해야 하는 사상 초유의 대규모 프로젝트이기도하다. 단기간내에 대규모로 추진하는 사업인 만큼 사회적 논쟁과 갈등이 심한 것도 사실이나 마침내 정부는 지난 6월 마스터플랜을 발표하였다. 앞으로 $2010{\sim}2012$년의 3년 기간 동안 엄청난 물량의 대규모 사업이 본격 추진될 전망이다. 이 글은 다음 두가지 측면에서 4대강 살리기사업의 특징 및 파급효과를 살펴보고자 한다. 첫째, 4대강 살리기사업의 내용 및 규모 등 주요 특징을 간략히 살펴보고자 한다. 둘째, 4대강 살리기사업의 국민경제 전체 및 건설산업과 시멘트산업 등에 미치는 경제적 파급효과를 살펴보고자 한다.

  • This study aims to examine the participation status and working conditions of seniors that participate in senior social activity support project, and analyze the influential relationship with subjective participation satisfaction based on participant attributes. In terms of the participation status, participating seniors became aware of the project through facilities and about 70% participated in the public interest type; the primary goal was for a short-term financial preservation. As an analysis result on participation effectiveness, longer participation period and time affected the participation seniors' working conditions and self-esteem negatively, implying that a flexible and effective operation of participation period is necessary. Also, while seniors with financial stability were more positively affected on their subjective satisfaction, other significant variables had negative effects. This study holds a significance in providing political implications as the basic data to improve and vitalize future senior social activity support project through the analysis of effectiveness, such as working conditions, self-esteem and subjective satisfaction based on participant attributes, including participant characteristics, participation status and participation degree.

  • This study is VE LCC case analysis on two school BTL projects which is constructed by Private sector and rented to government. Then private sector payback their initial cost and profit by rental fee from government. The VE in Korea, revised by the method of the Construction Technique - Enforcement Ordinance in 2005 is applicable to construction business which size is over 10 billion won. The VE well known as a way of productivity elevation is already proven and outstanding management method In construction industry inside and outside of the courtly. As its unique personality of BTL business, VE workshop period is too short. There is a few accomplished BTL project and data base, because BTL business begun from year of 2006. So we are trying to proof effect of VE LCC through case study of school BTL projects.

  • 통신사업은 일반 제조업에 비해 기간산업인 동시에 네트워크 산업으로서의 특성을 갖고 발달해왔다. 또한 통신산업은 현지의 시설을 기반으로 서비스가 전개되는 특성을 가지고 갖는다. 따라서, 전통적으로 국가별 독점사업자에 의해 발전해 왔으며, 사업허가 및 영업활동과 관련하여 규제당국의 역할 및 영향이 절대적이었다. 이러한 특성 및 과거의 방식에 비추어 최근의 통신사업 글로벌화 움직임은 기존의 사업체제를 크게 뒤흔드는 것이라 할 수 있다. 따라서, 최근 들어 매우 복잡한 양상으로 전개되고 있는 이 부문의 글로벌화 움직임을 올바로 파악하는 것은 통신사업자의 향후 전략수립을 위해서 필수적일 뿐만 아니라 통신부문의 특성이나 중요성에 비추어 기업활동의 글로벌화 및 글로벌전략 연구에 있어서도 의미 있는 일이라 생각된다. 이에 본 논문은 통신사업 글로벌화의 전개방향 및 해외사업자의 전략에 관한 종합적인 고찰과 분석을 통신사업 글로벌화의 특성을 파악·제시하며, 나아가 글로벌화와 관련하여 통신사업의 향후 발전방향에 대한 전망을 제시하고 있다.

  • 국가기간전산망사업의 일환으로 추진되고 있는 금융전산망사업은 금융기관의 급속한 전산화를 가져와 국민편의 확대는 물론 국제경쟁력 확보, 지급결제업무의 개선, 정책수립자료의 신속한 제공 등 많은 가시적 성과를 거두어 왔다. 이러한 금융전산망 사업은 그러나 은행.증권.보험.투자금융 등 각 업계별 전산화 뿐만 아니라 이들 전 금융기관이 공동참여하는 단일 전산망 구축문제, 그리고 외국은행 국내지점의 금융기관공동 전산망 가입 압력 등 대내외적으로 풀어나가야 할 산적한 많은 과제들을 안고 있다. 이에 본지는 대 국민 인식제고를 위해 금융전산망사업중 주도적으로 추진되고 있는 은행공동전산망의 종류와 내용, 추진현황, 향후전망과 과제 등을 알아본다.
