Global warming is happening now and inevitable. Everyone knows that immediate action should be taken to slow it down, but uncertain about the effective solution. Despite global efforts to reduce greenhouse gas emissions, sea levels are rising gradually. In 2013, Cornell University announced the Climate Action Plan(CAP) to make the campus greener, to reduce waste, and to ensure efficient use of resources. In particular, they set a goal of reducing energy use by 2050 and making carbon emissions to zero. Accordingly, the purpose of this study is to analyse the case of the master plan of Cornell Tech campus and its major buildings. Mainly, The House, faculty and student housing of Cornell Tech and the world tallest certified passive house, will be the main precedent that shows the architectural planning of passive house. Passive house technology, which was thought to be possible only in single-family houses, can be applied to high-rise buildings. If any passive house technology of The House project is actively introduced into the dormitory projects of domestic universities that are about to be built or renovated, it will be a good opportunity for the university to take the lead in preparing for global warming.

본 연구는 2012년 12월을 기준으로 디지털 전환이 완료된 시점에서 우리나라 유료방송 가입가구의 약 절반에 해당하는 가구가 디지털 전환의 수혜를 입지 못하는 초유의 사태가 여전히 진행 중이며, 이로 인해 구체적인 대안으로 떠오르고 있는 클리어 쾀과 8VSB 전송방식의 도입이 과연 타당한가에 대해 검토하고자 했다. 검토결과, 별도의 셋톱박스가 필요없는 클리어 쾀과 8VSB 방식은 사업자와 시청자의 경제적 부담을 덜어주고, 디지털 기술에 소외되기 쉬운 정보소외 계층을 포함시킬 수 있다는 장점이 있지만 전체 유료시장이 저가화되거나 콘텐츠 사업자의 저작권을 침해하는 등 콘텐츠 산업에 부정적인 영향을 미칠 것이라는 문제가 수반된다. 이로 인해 정부는 최소한의 수혜가구와 최소 채널을 지정해서 디지털 전환에 차질이 없되 관련 사업에 피해가 가지 않는 방향으로 정책적 목표를 설정할 필요가 있지만 상기한 우려가 쉽게 사라지지 않은 상황이다. 이에 대해 방통위는 한시적으로 두 가지 방법에 대해 개방적인 태도를 취할 필요가 있으며, 디지털 전환이 어느 정도 완성된 시점에서는 재고해야 할 것으로 판단된다.

RTCA DO-178C는 항공기 시스템의 감항성을 보장하기 위한 소프트웨어 개발 지침서이다. 하지만, DO-178C는 최대이륙중량 150kg 이상의 무인기 인증에 적용하는 것은 무인기로 인한 위험의 심각도(severity)가 보통의 항공기보다 낮기 때문에 과도한 규제라는 의견이 있다. 이러한 문제를 해결하기 위해, EASA와 FAA는 기존 항공기 인증 체계를 간소화 한 새로운 인증 체계 수립을 목표로 항공전자 인증표준 재편 및 간소화(RESSAC: Re-Engineering and Streamlining the Standards for Avionics Certification) 프로젝트를 2016년부터 수행하고 있다. 본 논문에서는 현재 적용되는 DO-178C 인증 프로세스를 분석하였고, DO-178C 인증 프로세스보다 과정 및 산출물을 간소화하면서도 비행 안전성을 확보 할 수 있는 새로운 RESSAC 인증 프로세스를 비교 분석하고 장점을 도출하여 제시하였다.

Decode-and-forward relaying is a promising enhancement to existing radio access networks and is already standardized in 3rd generation partnership project (3GPP) as a part of long term evolution (LTE)-Advanced Release 10. Two inband operation modes of relay nodes are supported, namely type 1 and type lb. Relay nodes promise to offer considerable gain for system capacity or coverage, depending on the deployment prioritization, in a cost-efficient way. Yet, in order to fully exploit the benefits of relaying, the inter-cell interference which is increased due to the presence of relay nodes should be limited. Moreover, large differences in the received power levels from different users should be avoided. The goal is to keep the receiver dynamic range low in order to retain the orthogonality of the single carrier-frequency division multiple access system. In this paper, an evaluation of the relay based heterogeneous deployment within the LTE-Advanced uplink framework is carried out by applying the standardized LTE Release 8 power control scheme both at evolved node B and relay nodes. In order to enhance the overall system performance, different power control optimization strategies are proposed for 3GPP urban and suburban scenarios. A comparison between type 1 and type 1b relay nodes is as well presented to study the effect of the relaying overhead on the system performance in inband relay deployments. Comprehensive system level simulations show that the power control is a crucial means to increase the cell edge and system capacities, to mitigate inter-cell interference and to adjust the receiver dynamic range for both relay node types.

In this paper, scale efficiencies and relative efficiencies of R&D projects in Industrial Technology Program, sponsored by Ministry of Trade, Industry and Energy, Korea, are calculated and compared. For the process, various DEA (Data Envelopment Analysis) models are adopted as major techniques. For DEA, two stage input oriented models are utilized for calculating the efficiencies. Next, the calculated efficiencies are grouped according to their subprograms (Industrial Material, IT Fusion, Nano Fusion, Energy Resources, and Resources Technology) and recipient types (Public Enterprise, Large Enterprise, Medium Enterprise, Small Enterprise, Lab., Univ., and etc.) respectively. Then various subprograms and recipient types are compared in terms of scale efficiencies (CCR models) and relative efficiencies (BCC models). In addition, the correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies is calculated, from which the causal relationship between them can be inferred. Statistical analysis shows that the amount of input, in general, should increase in order to be scale efficient (CCR models) regardless of the subprograms and recipient types, that the 1st and 2nd stage relative efficiencies are different in terms of the programs and recipient types (BCC models), and that there is no significant correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies. However, the results should be used only as reference because the goal each and every subprogram has is different and the situation each and every recipient type faces is different. In addition, the causal link between the 1st stage relative efficiencies and the 2nd relative efficiencies is not considered, which, in turn, is the limitation of this paper.

The research presented here represents a collaborative effort with the SFWMD on developing scenarios for future climate for the SFWMD area. The project focuses on developing methodology for simulating precipitation representing both natural quasi-oscillatory modes of variability in these climate variables and also the secular trends projected by the IPCC scenarios that are publicly available. This study specifically provides the results for precipitation modeling. The starting point for the modeling was the work of Tebaldi et al that is considered one of the benchmarks for bias correction and model combination in this context. This model was extended in the framework of a Hierarchical Bayesian Model (HBM) to formally and simultaneously consider biases between the models and observations over the historical period and trends in the observations and models out to the end of the 21st century in line with the different ensemble model simulations from the IPCC scenarios. The low frequency variability is modeled using the previously developed Wavelet Autoregressive Model (WARM), with a correction to preserve the variance associated with the full series from the HBM projections. The assumption here is that there is no useful information in the IPCC models as to the change in the low frequency variability of the regional, seasonal precipitation. This assumption is based on a preliminary analysis of these models historical and future output. Thus, preserving the low frequency structure from the historical series into the future emerges as a pragmatic goal. We find that there are significant biases between the observations and the base case scenarios for precipitation. The biases vary across models, and are shrunk using posterior maximum likelihood to allow some models to depart from the central tendency while allowing others to cluster and reduce biases by averaging. The projected changes in the future precipitation are small compared to the bias between model base run and observations and also relative to the inter-annual and decadal variability in the precipitation.

Background: Intersectoral and multidisciplinary collaboration is becoming more prominent in all facets of government, health, social services, and scientific endeavors. An interplay of a multitude of driving forces moves multiple disciplines forward to achieve quality outcomes in health and social sciences services and research. Aim: This paper aims at discussing the prospects for future multidisciplinary collaboration. If inter organizational integration and multidisciplinary collaboration are the ways of the future in academia and the scientific world, it then becomes crucial to examine what lies ahead for the nursing profession, Discussion: This paper argues that in order for multidisciplinary endeavors to succeed, the leaders in multidisciplinary teams shoulder the largest share of the responsibilities involved. In developing a lasting team constituting professionals from different disciplines, the leader needs to include the right individuals in the team, identify a common goal, build trusting relationships through open communication and interprofessional education, and empower members through creating room for autonomy and at the same time allowing space for personal development. The leader will need to utilize information technologies to manage communication issues in a large multi-site multidisciplinary project. Lastly, he or she must be able to demonstrate team productivity through process and outcome evaluation. It needs to be emphasized that it falls to each individual nurse to speak up and act upon what nursing believes and represents in our quest for success in multidisciplinary endeavors. Conclusion: The significance of the role of the leader is paramount for a team to succeed. Yet there is no prospect if only a handful of exceptional nurse leaders are moving ahead in multidisciplinary endeavors. Without the actualization of professional roles by each individual nurse, the profession will have no prospect in collaborations across disciplines.
