  • 이 논문은 2013년 순천시에서 열린 2013순천만국제정원박람회 개최구상이 지역정책으로 구체화되는 과정에 대한 특징과 영향요인을 고찰하였다. 정원박람회 개최구상의 정책화 과정은 제1단계(1992-2002)인 순천만 보전운동 태동기, 제2단계(2003-2007)인 순천만 자연생태공원 조성기, 제3단계(2008-2010), 정원박람회 개최구상 정책화 및 박람회 유치기, 제4단계(2011-2013)인 박람회장 조성 및 박람회 개최기 등으로 구분되었다. 정원박람회 정책화 과정에는 많은 사회 정치적 요인들이 복합적으로 작용하였지만, 순천만 존재와 순천만 보전을 위한 시민운동, 광양만권에서 중심도시를 유지 강화하려는 순천시 도시발전전략, 도시정책 연속성을 유지한 지자체장과 지역사회의 리더십, 인접한 여수시와의 연대와 경쟁의식 등이 중요한 동인으로 작용하였다. 또한 메가 이벤트 개최를 통해 순천시는 도시이미지 개선, 순천만정원이라는 공공재 확보, 환경을 중시하는 도시정책을 추진한 지역사회의 리더십 구축 등에서 일정한 성과를 확보한 것으로 평가받고 있다.

  • Hong Kong is a renowned small city with densely placed skyscrapers. It is no surprise that heavy duty or even mega foundations are built over the years to support these structures. To cope with the fast construction pace, several heavy deep foundation types have been widely adopted with some prescribed design rules. This Paper has selected two commonly adopted but distinctive foundation types, namely large diameter bored piles and percussive steel H-piles to illustrate the special design and construction considerations related to these pile types in related to local context. The supervision requirement in related to foundation works for which again may be unique in Hong Kong will also be highlighted. A case history is also discussed in the later part of the Paper to illustrate the application of one of these foundations and to highlight the importance of considering foundation design and basement excavation method in a holistic manner.

  • This paper presents experimental and numerical studies into the structural behavior of a high performance corbel type composite connection adopted in Raffles City of Hangzhou, China. Physical tests under both monotonic and quasi-static cyclic loads were conducted to investigate the load carrying capacities and deformation characteristics of this new type of composite connection. A variety of structural responses are examined in detail, including load-deformation characteristics, the development of sectional direct and shear strains, and the history of cumulative plastic deformation and energy. A three-dimensional finite element model built up with solid elements was also proposed for the verification against test results. The studies demonstrate the high rigidity, strength and rotation capacities of the corbel type composite connections, and give detailed structural understanding for engineering design and practice. Structural engineers are encouraged to adopt the proposed corbel type composite connections in mega high-rise buildings to achieve an economical and buildable and architectural friendly engineering solution.

  • Measurement of the phosphorus concentration in aerosols in Beijing, which was a representative East Asian mega-city, was carried out. The optimum procedure for analyzing phosphorus in aerosols was found in this study. Recovery of phosphorus in environmental samples through the improved method was almost 100%. The concentration of phosphorus in TSP was $145{\pm}47\;ng/m^3$, with a seasonal variation showing high concentrations in winter and low concentrations in summer. The concentrations of phosphorus in $PM_{2.5}$ accounted for $35{\pm}6%$ of those in TSP, with no seasonal variations. The major source of phosphorus in aerosols in Beijing was soil dust, and additional sources of phosphorus in fine particles could be coal combustion and biomass burning.

  • In 2006, Korean Government decided to relocate the several Government bodies and public institutes. They include total of 49 central Government agencies, semi-government agencies, and 17 national research institutes. The completion of the relocation program has been set to be final in 2030. The target population for the city plan is set to be 500,000. The goal of MAC is first to complete the first phase of the program by 2014 within the budget. In order to achieve the goal, considerable time has been spent to properly establish the program management system. The success of MAC's Multi-function Program Administration System is too early to determine as it is still in progressive. The success depends on the operations not the development.

  • 서울은 많은 인구 및 도시 기능이 집중된 거대 도시로, 재난 및 위급상황이 발생하였을 때 긴급하게 대피할 수 있는 장소는 필수적이다. 현재 서울시 대피소의 숫자는 수용능력 면에서 보면 서울시 인구의 두 배 이상을 상회하고 있다. 하지만 서울의 경우, 거주지의 인구분포와 유동인구를 포함한 낮 시간대의 인구분포는 상이하다. 따라서 대피소의 실질적인 수용성을 분석하기 위해서는 수도권 인구 분포의 유동적인 특성을 고려할 필요가 있다. 이에 본 연구에서는 수도권의 유동인구자료를 활용하여 서울시 대피소의 실질적인 접근성 및 수용능력을 분석하고자 하였다. 이를 위해 보행자 도로망을 이용한 네트워크 분석을 통해 대피소의 접근성을 파악하고 거주인구 및 유동인구에 따른 지역적 수용능력의 차이를 분석하였으며, 연구지역 내 대피소의 분포에 따라 취약한 지역과 현재의 대피소 위치 선정에 대한 문제점을 도출할 수 있었다.

  • 국내외적으로 수주량이 증가하고 있는 대형 구조물의 건설 시 보다 정밀한 시공 및 유지관리 기술이 요구 된다. 그 중 콘크리트의 강도는 대표적인 품질관리 변수 중 하나로, 정확한 강도 값의 측정 및 이력관리는 건설 프로세스에서의 공기단축을 통한 비용 절감 및 효율적인 시공관리를 위해 매우 중요한 요구 사항이다. 이에 이 논문에서는 유비쿼터스 시대에 적합한 건설시공기술로의 발전을 위해 최근 개발된 임베디드 자율 감지형 콘크리트 강도 모니터링 기술을 데이터베이스화하고 이를 QR(quick response)코드와 연동시키는 콘크리트 강도 라벨링 기술을 소개한다. 이를 통하여 콘크리트 구조물의 강도 이력 DB를 언제 어디서나 실시간으로 확인하고 이를 바탕으로 보다 정밀하고 경제적인 시공 및 유지관리할 수 있는 차세대 콘크리트 생애주기 품질관리 시스템으로의 실현 가능성에 대해 고찰해본다.

  • This study categorizes and identifies the characteristics of the living areas of rural dwellers through cluster analysis using mobile floating population data. As a result, rural areas in Korea were classified into 34 rural living areas, and 5 types of rural living areas were derived. Although the 'Suburban in Mega City Areas' and 'Suburban in Regional City Areas' derived through this study have advantages in terms of accessibility to large cities, they are important for rural space management as they can undermine the unique values of rural areas due to urban expansion. In addition, 'Unclassified areas' have low accessibility in the national space, and there is a need to provide their own settlement environment. The population of rural areas in Korea exhibited a phenomenon of widespread migration. This means that rural residents who depend on metropolitan areas are provided with SOC beyond administrative boundaries. Therefore, there is a need to move away from establishing a homogeneous regional plan that does not consider population movement. Through this study, it was possible to understand the rural living area formed by the population movement occurring in the rural area. This is different in that the existing studies classified the national space based on the interconnectedness between regions, beyond the limitations of categorizing regions with homogeneous characteristics based on endogenous indicators. At this point in time when the need for a rural space plan is emphasized, it is important to understand the living area of rural dwellers and to design an appropriate rural plan. Therefore, the establishment of a rural plan suitable for the region using the results of this study can increase the efficiency of the project for revitalization of the rural area and contribute to the creation of an attractive national space.

  • 이태리 출생의 미국 건축가 파올로 솔레리(Paolo Soleri, 1919-2013)는 아르콜로지(arcology)의 개념을 통한 급진적인 생태도시안을 발표하여 큰 주목을 받았다. 건축(architecture)과 생태(ecology)를 결합한 신조어 아르콜로지는 휴머니즘을 토대로 한 문화적 연속성과 과학기술을 기반으로 한 지속가능성이 반영되었지만, 초거대 스케일(mega-scale)과 유토피아적인 성격덕분에 도발적이고 비현실적이라는 비판도 받았다. 솔레리의 아르콜로지는 그가 출판한 여러 권의 책을 통해 소개된 바 있지만, 아쉽게도 구체적인 내용은 명확히 정리되지 않고 산만하게 남아있다. 본 논문은 솔레리가 제안한 아르콜로지의 개념과 구성요소를 친환경 건축도시이론으로 규정하고, 그 실체적인 현상으로 아르코산티(Arcosanti)가 어떻게 구현되었는지 실증적으로 파악하고자 했다.

  • Purpose: This study was to identify the effects of simulation-based training for advanced cardic life support on the competence of nurses in critical care settings. Methods: In this study, a nonequivalent control pretest-post test quasi-experimental design was used. Data were collected from May 1 to June 1, 2006 at one general hospital in W city. Among 40 nurses in critical care settings, twenty were assigned to the experimental group and twenty to the control group. Nurses in the experimental group received simulation-based training for advanced cardiac life support. Measurement tool were ACLS related knowledge and skills developed by AHA & Mega Code (2005) and some items were modified. The collected data were statistically processed using SPSS version 12.0 for Windows, and analyzed using descriptive statistics, $X^2$test, t-test, paired ttest, Pearson correlation coefficients. Results: 1) Hypothesis 1“: Nurses who received simulationbased training would have more knowledge of advanced cardiac life support than nurses who received traditional training”, was supported (t=11.51, p=.00). 2) Hypothesis 2: “Nurses who received simulation-based training would have better advanced cardiac life support skills than nurses who received traditional training”, was supported (t=2.38, p=.00). Conclusion: Simulation-based training for advanced cardiac life support is an effective strategy for increasing the competence of nurses in advanced cardiac life support in critical care settings.
