  • 2009년 Arikan에 의해 처음 제안된 극 부호(polar codes)는 실용적인 부 복호화 복잡도로 채널 용량을 달성하는 것이 종영된 채널 부호이다. 채널 양극화(channel polarization) 현상을 이용하는 극 부호는 현재 보안 및 데이터 압축 등에 응용되어 활발히 연구되고 있다. 본 논문에서는 극 부호의 실제 통신 시스템 적용을 고려하여, 유한한 길이와 고정 부호율을 갖는 극 부호의 설계 방법을 제안한다. 그리고 모의실험을 통하여 경험적으로 찾아낸 가장 우수한 성능을 보이는 극 부호의 성능과 설계 방법을 제시한다.

  • 최근 건설 산업은 정보기술을 접목하여 효율성과 경쟁력을 높이는데 많은 관심을 가지고 있다. 그 중에서도 RFID는 다양한 분야에 적용되고 있으나 건설 산업의 기본 요소 인 건설자재에는 다양한 물리적, 화학적 특성 및 사용 환경 요인 등으로 인하여 적용이 용이하지 않아 현장에 적용 사례가 많지 않은 것으로 파악되고 있다. RFID를 건설 산업에 효율적으로 적용하기 위해서는 먼저 RFID 코드발급과 이를 체계적으로 관리할 수 있는 체계가 마련되어야 하고 두 번째로 건설자재 적용을 위한 주파수, 사양, 프로토콜, 패키지방법, 인식 방법 등의 표준화연구가 필수적이다. 본 연구에서는 RFID코드발급과 관리방안을 마련하고 건설자재에 적합한 RFID Tag을 선정하기 위하여 건설자재의 물성/환경적 특성 분석, 건설자재의 현장 도입 및 관리 단위, 관리형태 등을 분석하여 건설자재별 적합한 RFID 태그를 선정하고자 진행되었다. 현장 실험은 건설현장 반입 및 관리 단계로 구분하여 실험을 실시하였다. 다양한 실험 결과는 향후 건설현장에서 RFID를 활용할 경우 시행착오를 줄일수 있는 좋은 사례가 될 수 있을 것이다.

  • Landscaping on building sites has been regulated by Building Code in Korea. By Article 42 of the Code, landscaping is mandated in the process of building construction and people should comply with the code to get the building permit. On the other hand, sustainability tends to be a prime value these days. Because of the intrinsic nature of Korea Building Code, the landscaping was not adequately implemented in reality. After studies on the landscape ordinance, the major problems on the mandated landscaping has been speculated as follows: 1. As far as landscaping has been regulated by single building code, there seems to be a limitation. Urban Planning Code etc. would be another mean to adequate landscaping. 2. Speculations on landscape details associated with landscape plans are needed for building permit process. 3. By any level of law, the landscape should be reinforced for public buildings and developments because of its own publicity. 4. Locally sound landscape would be implemented through Special Architectural District etc.

  • With the rise of BIM application and green building assessment, studies on assessment of CO2 emissions from buildings using BIM are needed. In accordance with the requirements, this study aims at developing BIM Template database, as a part of development of CO2 assessment technology using BIM. Based on the research of construction materials, this study develops database by applying Procurement Agency Item Code to BIM Template. The results of this research makes it possible to assess CO2 emissions of materials with BIM Template and building data modeling implementation.

  • This study is under doing to suggest application manual using assembling reference plane design & standard finish material basis upon material classification code as a tool of a linkage between building design and construction standarization in order to enlarge the applicability of house building material that is produced by the module plant. We can say the goal of building standardization intend not only the improvement of construction productibility but also guarantee of subsequent performance through automatization basis upon informationalization of building design. For a etabilishing of this condition, it is neccessary to link the standardization's result of material--design--construction field. According to this neccessity, we are going to suggest information factor that can make relative business manager easily approach to the standardization practical task.

  • Recently, auger-drilled piling has been widely used in urban area to reduce the air pollution and noise. But this construction method that its basic theory was introduced from Japan may be changed depending on the each piling company and construction field condition. Therefore, the design code and management method for auger-drilled piling is not defined yet. Especially, the lack of research on the bearing capacity of auger-drilled piling leads to the absence of rational bearing capacity prediction equation. This paper presents the optimum design code and economical construction method of the auger-drilled piling by proposing the new bearing capacity prediction equation based on the site specific soil types and construction conditions. In this paper, existing bearing capacity prediction equations and current pile load tests were compared. And the end bearing capacity and skin friction characteristics were also analyzed by comparing the results of CAPWAP. From the results of analysis, a reliable bearing capacity prediction equation considered soil types is proposed.

  • Purpose: The purpose of this cross-sectional study was to examine current status of IT-based medication error prevention system construction and the relationships among system construction, medication error management climate and perception for system use. Methods: The participants were 124 patient safety chief managers working for 124 hospitals with over 300 beds in Korea. The characteristics of the participants, construction status and perception of systems (electric pharmacopoeia, electric drug dosage calculation system, computer-based patient safety reporting and bar-code system) and medication error management climate were measured in this study. The data were collected between June and August 2011. Descriptive statistics, partial Pearson correlation and MANCOVA were used for data analysis. Results: Electric pharmacopoeia were constructed in 67.7% of participating hospitals, computer-based patient safety reporting systems were constructed in 50.8%, electric drug dosage calculation systems were in use in 32.3%. Bar-code systems showed up the lowest construction rate at 16.1% of Korean hospitals. Higher rates of construction of IT-based medication error prevention systems resulted in greater safety and a more positive error management climate prevailed. Conclusion: The supportive strategies for improving perception for use of IT-based systems would add to system construction, and positive error management climate would be more easily promoted.

  • This study is aimed at utilizing LCA processor with BIM LOD, eliciting the problems of the existing environmental assessment by constructing the database for environmental values of green buildings. For these objects, environmental load database of BIM construction material and evaluation process are presented, after matching BIM family based environmental load database which is available during evaluation stage, input-output tables and Korea LCI database to standard item code of public procurement service. It is a important factor in environmental assessment of building to develop database unit of standard item code for BIM and construction material. Thus, the results of this study are expected to provide basic data for improving effectiveness of construction through BIM based environmental load evaluation database. Furthermore, the provided environmental load database unit for construction material is considered to be available as basic information for BIM study by suggesting a processor connecting BIM with LCA and along with this, continuous examination on the connection process is needed.
