Since the global financial crisis, the Korean domestic construction market has continuously experienced downturns, and the Korean domain construction firms'profitability has been persistently deteriorated. Domestic construction firms have rapidly advanced to overseas markets exclusively for the construction contract packages. However, the profitability for the construction contracts has been lower compared to engineering or project management contracts. One of the critical issues the Korean firms have faced was project management capability across all phases in project execution. Even though several project management capability assessment tools were introduced, most tools were applicable to a wide variety of industry sectors rather than construction industry. Project management capability assessment tool specifically applicable to domestic CM firms was developed through this research, in order to assess project and program management capabilities and improve the competitiveness in overseas market Also, the correlation between project, programs, and the CM infrastructure were identified. The CM firms were divided into two groups according to the size of the business, and both were evaluated at the project and the program level based for the 9 different criteria. The project management capability assessment tool developed for the CM firms can be used for self-assessment to distinguish the strengths and weaknesses of each company at the project and program level. In addition, the current status of each group can be identified by spotting improvement areas for the management capabilities.

2020년 기준 우리나라 전체 지하수 시설은 총 1,659천개소, 이용량은 2,916백만m³/년, 년간 지하수 개발가능량은 130억m³대비 22.3%이다(환경부 등, 2021). 단위면적당 지하수 시설수와 이용량은 16.8개소/km², 29,168m³/년/km²(81.1m3/일/km²)이다. 이러한 자료는 가뭄 대응시 신규 관정 개발도 필요하지만, 기존에 개발된 관정들을 최대한 효율적으로 활용하는 방안을 우선적으로 고려해야 한다는 것을 시사한다. 관정들을 상호 연계하게 되면 여러 개의 관정에서 나오는 물을 합하여 총량을 늘릴 수 있기 때문에, 가뭄 등 비상시에 일시적으로 다량의 물을 공급할 수 있다. 또한, 평상시에도 적절한 양수량 조절을 통해 지하수 자원의 손실을 막고 수위 저하에 의한 문제를 최소화할 수 있다. 관정연계시스템(well network system, WNS)은 기존 관정들을 가상의(virtually) 또는 물리적(physical) 연계를 하여, 최적의 지하수를 공급할 수 있는 시스템으로 정의할 수 있다. 가뭄 대응 및 효율적 지하수 자원 활용을 위한 관정연계시스템 개발과 실증을 위해 홍성군 서부면 양곡리 일대에 양수제어, 관로시설, 물탱크 등 물리적인 시설을 시험 설치하여 운영하고 있다. 또한, 관정연계시스템은 ICT 기술과 지하수관리 기법을 연동하여 지하수 관정들을 연계하고 최적으로 운영할 수 있는 하나의 의사결정시스템으로서 관정연계 플랫폼을 개발하였다. 관정연계 플랫폼은 웹기반으로 개발되었으며, 대수층의 수리지질 특성, 수요에 기반한 물공급량 평가, 관정 연계 시나리오 및 최적 운영 알고리즘, 지하수 모델링 등이 가능하도록 각각의 모듈들이 구성 및 통합·운영 되도록 설계되었다. 본 시스템 개발을 통해 가뭄 발생시 현장에서 신속히 지하수로 물을 공급할 수 있으며, 신규 관정 개발에 드는 비용을 절약할 수 있고, 기존 시설을 활용하기 때문에 새로운 수자원 건설 인프라 구축 비용도 절감할 수 있을 것이다. 또한, 개별관정에 대한 이용률 제고와 지하수관리도 보다 체계적, 과학적으로 할 수 있을 것으로 기대한다. 하지만, 이러한 시스템이 제대로 운영 및 보급되기 위해서는 관정연계와 관련한 법제도적 보완과 함께, 지역사회의 공적자원으로서의 지하수에 대한 인식개선과 지하수의 개발 및 보전, 적합한 합리적 배분·이용 등 적극적인 협조가 이루어져야 한다.

2022년 중부권은 집중호우에 의해 큰 피해를 입었다. 2022년 서울의 강수량은 1775.3mm로 30년(1993~2022년) 연평균 강수량(1429.6mm)을 상회하였고, 6월~9월에 1412.4mm로 약 80%의 강수량이 집중되었다. 또한, RCP(Representative concentrate pathways) 기후변화 시나리오에 따르면 2100년까지 강수량과 강우지속시간이 지속적으로 증가할 것으로 예측하고 있다. 뿐만 아니라, 도시화는 지속적으로 불투수면적을 넓히고 있어, 도시지역의 홍수피해는 점차 가중될 것으로 판단된다. 본 연구에서는 도시지역 불투수면적의 투수화를 통해 강수량을 지표하로 침투시켜 지표유출을 저감하는 방안을 연구하였다. 대상지는 부산광역시 신도시 개발지역으로 30년 강우자료를 이용하여 무강우 지속시간, 독립 강우사상의 구분, 강우사상의 지속시간 및 분포 등을 분석하여 빗물관리목표를 설정하였다. 해당 빗물관리목표를 만족시킬 수 있는 규모의 저영향개발 시설을 적용하였고, 도시지역의 개발 전, 개발 후, 저영향개발 기술 적용 후의 단계로 구분하여 모의분석을 수행하였다. 개발 전의 물순환 회복률을 100.0%로 기준을 설정하고, 모의분석 결과 개발 이후 38.1%로 물순환 회복률이 급감하였으나, 저영향개발 기술 적용을 통해 약 92.0%로 회복되는 것을 확인하였다. 이후 연별, 월별 물수지 분석을 통해 물순환 회복률과 지표유출 저감 정도를 비교 분석하였다. 이상의 결과를 통해 저영향개발의 적용으로 도시화와 집중호우로 인한 도시지역의 수해를 일부 저감시킬 수 있을 것으로 판단되고, 대상지역 개발 전의 물수지 상태 회귀를 통해 지속가능한 발전이 가능할 것으로 기대된다.

As digital systems were introduced to automotive design in the mid 1980s, the design process has adopted many digital programs to save time compared to the conventional hand drafting. Digital technology was introduced not only to satisfy the reeds of the global environment, as the number of automobiles exported to many different parts of the world has increased, but also to save time and effort in developing several models of quality automobiles. Therefore, every automotive manufacturer in the world has expanded its virtual reality(VR) studio to establish visualization systems that visualize automobiles in the actual size and a co-operation system that enables simultaneous feedback from all of its design studios around the world. Unlike the existing design reviewing methos, the new improved feedback system is assessed as a reasonable method to evaluates and understand how the automobiles are actually manufactured in simulation. It is especially helpful when advanced products and concept cars require fast results. Other strengths of the new system include shorter development period, cost efficiency, no more manual labor, various designs within a short period of time, and realistic visualization of concepts. Large-scale products, including automobiles, need to be projected in the actual size and high clarity through the Power-wall System and are examined in a virtual space called a Cave. Therefore, it took much time to establish digital infrastructure. An infrastructure would constantly require system improvement and performance enhancement, but it is certain that now is the right time for the take-off to utilizing the strengths of digital design and improve the weaknesses. In this respect, this study provided an understanding of the importance of digital design based on digital reinforcements and examined an effective utilization of digital technology for an efficient development of automobiles in the future.

This study developed low-cost and high-efficiency pavement condition monitoring technology to produce the key information required for pavement management. A noise and artificial intelligence-based monitoring system was devised to compensate for the shortcomings of existing high-end equipment that relies on visual information and high-end sensors. From idea establishment to system development, functional definition, information flow, architecture design, and finally, on-site field evaluations were carried out. As a result, confidence in the high level of artificial intelligence evaluation was secured. In addition, hardware and software elements and well-organized guidelines on system utilization were developed. The on-site evaluation process confirmed that non-experts could easily and quickly investigate and visualized the data. The evaluation results could support the management works of road managers. Furthermore, it could improve the completeness of the technologies, such as prior discriminating techniques for external conditions that are not considered in AI learning, system simplification, and variable speed response techniques. This paper presents a new paradigm for pavement monitoring technology that has lasted since the 1960s.

The role of R&D center for technology commercialization can be categorized into three distinct stages: the first stage consists in developing industrial problem-solving capability; the second consists in catching up with industrialized economies developing creative imitations of imported technologies; and the third consists in acquiring advanced knowledge creation capability. Accordingly, the R&D center's organization should be aligned with this development strategy. This case study of Kazakhstan provide a managerial implication for the other developing countries. The first stage of development, which may be called the 'industrial problem solving stage,' the center will build the infrastructure in terms of both technology and human-resources. The second stage will involve building up 'knowledge capability' with a view to becoming a major industrial R&D hub in Central Eurasia. In the third stage, the center will create advanced knowledge as a 'world-class knowledge center'. In this regard, the evolution of the R&D center should be described according to the features of the center's services.

ODA is an effort and action of international community to keep human rights by eradicating poverty. UN declared MDGs (Millennium Development Goals) during 2001 and 2015. As a follow-up action, UN sets up SDGs (Sustainable Development Goals) during 2016 and 2030. SDGs expands the concept of ODA. SDGs includes cooperation development over the scope of ODA by mobilizing various financial resources from public sectors and private sectors. It will overcome the limitation of traditional ODA and be 'AID and beyond'. Catalytic aid is appropriate for the concept of SDGs. Cooperation development by catalytic aid focuses on building economic infrastructure and production facilities rather than humanitarian aid, which will establish a sustainable development basis for recipient countries. This study suggests to make a PPP business by linking KSP(Knowledge Sharing Program), to objectify criteria of priority recipient selection and aid allocation, to adapt grant and concessional loan complexly according to the business, to support realization of CSV(Creating Shared Value) by establishing SPC(Special Purpose Company) and to construct a PCSD(Policy Coherence for Sustainable Development) system to fulfill the fore-mentioned strategies.
