[en] This report describes a method and process assigning a value for system functions to categorize the safety-significant SSCs(Structures, Systems, Components) in graded quality assurance(GQA). In this study, we used the Delphi process for elicitation of the expert opinions. In Delphi Process, it is required to use a guideline for consistency. Therefore, we developed the guideline for SSCs categorization. This guideline was written to assign a value for system functions to screen out the safety-significant SSCs. This guideline provides with the requirement for an ideal expert panel composition, questionnaire, the description for issues and the guide assigning values
[en] Persons with disabilities in Indonesia increase significantly every year. The average increase of the number disabilities from 2012 to 2017 was 4.8%. Increasing the number of disabilities is not followed by an increase in accessibility and mobility for people with disabilities. This causes dependency and barriers for persons with disabilities to have similarity opportunities for decent living. There are 33% of people with disabilities have difficulties in walking and needing access to mobility. In addition, the availability of mobility devices in Indonesia is minimal. So in this study trying to design a mobility devices for entering a car for wheelchair users with comparative study from previous studies using the AHP method and the Delphi method. The purpose of the design is to solve dependencies and barriers in accessibility and mobility of wheelchair users. The output obtained is visualization design concept of wheelchair user transfer for entering and leaving a car according to the specified design requirement criteria. (paper)
[en] Highlights: • Integrated key findings derived from three interdependent analytical phases. • Obtained a collective view of shipping experts pertaining to safety leadership. • Developed and validated a weighted safety leadership model in shipping context. • Effective safety leadership behaviours were articulated, verified and prioritized. • Provided practical standard/basis for accelerating safety leadership development. - Abstract: Recent years have witnessed a growing concern for safety and highlighted the importance of leadership in safety practice within high-risk organizations. By following up and integrating the state-of-art research trends, this study aims at (1) bridging a gap in safety leadership research – i.e., the lack of a holistic understanding of safety leadership contribution at all managerial levels within high-risk organizations; (2) developing and validating a weighted safety leadership model in the context of shipping which incorporates key safety leadership behaviors that may enable researchers and practitioners to better understand and exercise safety leadership in shipping organizations. To systematically fulfill the research aims, this study integrates both numerical and descriptive data by sequentially applying three interdependent research techniques – namely inductive analysis of literature, modified Delphi method and Analytical Hierarchy Process (AHP). The study results in a holistic weighted model with concrete safety leadership behaviors at each managerial level, which contributes to the building of theoretical foundations in the domain of safety leadership research and serves as practical standards for accelerating safety leadership development in shipping organizations.
[en] This Paper aimed at looking for the new growth engines in the nuclear R and D field which leads the national prosperity and people's welfare in the 21st Century. As new growth engines in the nuclear R and D field, 17 innovative technologies(eight nuclear energy innovation system technologies and nine radiation fusion technologies) were selected. Selected technologies were evaluated through a expert group's peer review in accordance with criteria such as the aspect of technology, economy, and national strategy. In accordance with the expected commercialization time of the innovative technologies in the leading countries, these were categorized into two or three groups and In the aspect of their technology development level, 20 ∼ 40% technological gaps were shown. According to the business aspect, it was expected that innovative nuclear technologies selected as the new growth engines would have world markets of the range of 0.01 ∼ 100 billion $/year and the sales of 0.001 ∼ 10 billion $/year. Technology development strategy was suggested through colligation of the expert survey and an innovation theory. From the viewpoint of innovation stage, most of new growth engines in the nuclear R and D field were in position of the transitional phase(world) and the adaption stage(home). It was required that process and product technologies should be standardization in accordance with each innovation stage. For the successful commercialization, it was more important that R and D capability in R and D institutions should be improved and that appropriate funding and R and D infra should be well established and supportive. The results of this study will contribute to the establishment of the effective technology development strategy in the nuclear R and D field
[en] Quality indicators (QIs) have been developed for many aspects of prostate cancer care, but are under-developed with regard to radiotherapy treatment. We aimed to develop a valid, relevant and feasible set of core QIs to measure quality of radiotherapy care in men with prostate cancer.
[en] We present a set of indicators of vulnerability and capacity to adapt to climate variability, and by extension climate change, derived using a novel empirical analysis of data aggregated at the national level on a decadal timescale. The analysis is based on a conceptual framework in which risk is viewed in terms of outcome, and is a function of physically defined climate hazards and socially constructed vulnerability. Climate outcomes are represented by mortality from climate-related disasters, using the emergency events database data set, statistical relationships between mortality and a shortlist of potential proxies for vulnerability are used to identify key vulnerability indicators. We find that 11 key indicators exhibit a strong relationship with decadally aggregated mortality associated with climate-related disasters. Validation of indicators, relationships between vulnerability and adaptive capacity, and the sensitivity of subsequent vulnerability assessments to different sets of weightings are explored using expert judgement data, collected through a focus group exercise. The data are used to provide a robust assessment of vulnerability to climate-related mortality at the national level, and represent an entry point to more detailed explorations of vulnerability and adaptive capacity. They indicate that the most vulnerable nations are those situated in sub-Saharan Africa and those that have recently experienced conflict. Adaptive capacity - one element of vulnerability - is associated predominantly with governance, civil and political rights, and literacy. (author)
[en] Spectral moments in semileptonic B decays provide much information on the theoretical parameters describing these transitions. The DELPHI collaboration has measured the three first spectral moments of the hadronic mass distribution and of the lepton energy spectrum. From them, non-perturbative parameters such as the heavy quark masses and the b-quark kinetic energy value are determined. Using different formalisms, the value of the CKM matrix element Vcb is extracted with higher and better controlled accuracy. (Author) 7 refs
[en] Several new particle searches have been performed in the DELPHI experiment involving τ leptons in the resulting final state. The topology and special characteristics of the T leptons have been used to discriminate the signal from the Standard Model background. Limits on new particles have been set, playing an important role the channels with τ leptons
[en] Preliminary evidence on the long-run trajectory of the accelerator industry suggests that it may be close to the maturity phase of its cycle. If this is the case, how can we measure the benefits of an uncertain breakthrough in acceleration technology? Who are the main stakeholders interested by such a breakthrough? We identify these subjects and sketch some avenues for answering these questions. We thus present a model for the social Cost–Benefit Analysis (CBA) of research infrastructures and illustrate the results of its implementation for assessing the benefits of accelerators in basic science and hadrontherapy. Lastly, we move from the social CBA of single research infrastructures to modeling a major change in the accelerator technology and hence in the industry. A research agenda on the potential impacts of a technological breakthrough is presented.
[en] Highlights: • Dehesas' sustainability is endangered by low profitability and dependence on subsidies. • Current management can jeopardize the maintenance and persistence of dehesa farms. • Specific tools are needed so that farm managers can assess sustainability in an easy and reliable way. • Delphi method has been used to design a set of sustainability indicators adapted to dehesas. • Indicators were selected based on consensus and representativeness regarding sustainability pillars. This paper provides a list of specific indicators that will allow the managers of dehesa farms to assess their sustainability in an easy and reliable way. To this end a Delphi analysis has been carried out with a group of experts in agroforestry systems and sustainability. A total of 30 experts from public institutions, farming, research bodies, environmental and rural development associations, agricultural organizations and companies took part in the study which intended to design a set of sustainability indicators adapted to dehesa agroforestry systems. The experts scored 83 original indicators related to the basic pillars of sustainability (environmental, social and economic) through a two-round procedure. Finally, 24 indicators were selected based on their importance and the consensus achieved. From an environmental point of view, and in line with its significance for dehesa ecosystems, it has been observed that “Stocking rate” is the indicator with greater relevance. Within the economic pillar, “Farm profitability” is the most important indicator, while regarding the technical indicators “Percentage of animal diet based on grazing” is the one that got the highest score. Finally, the “Degree of job satisfaction” and the “Generational renewal” were the most relevant labor indicators. It is considered that the Delphi approach used in this research settles some of the flaws of other sustainability models, such as the adaptation to the system to be studied and the involvement of stakeholders in the design.
