[en] We have shown and have developed a new type of nuclear data retrieval system, in which a nuclear reaction data compilation is applied as an example. To get benefits from recent computer and network technologies, we adopt the IntelligentPad architecture as a framework of the present system. We set the future aim of our database system toward the 'effective' use of nuclear reaction data: I. 'Re-produce, Re-edit, Re-use', II. 'Circulation, Evolution', III. 'Knowledge discovery'. We discuss the appropriate concepts, which fit for the above purpose. (author)
[en] The project is proposed for creation of interactive data bank obtained for 30 years on LHE, JINR plants using chamber methods. These data are the good basic material both for independent investigation and for checking up of theoretical predictions, simulation of new experiments and applied investigation. The creation of data bank in accordance with proposed project allows one to keep unique, often having no world analogies, data on nucleon-nucleon, nucleon-nucleus interactions at energies from 1 to 40 GeV, obtained under 4π- geometry condition, and ensures for physicists from various scientific centres the direct and comfortable access to these data by INTERNET using WWW-interface. 13 refs., 1 fig., 7 tabs
[en] Electronic word of mouth (eWOM) plays a crucial role in influencing purchasing decisions of consumers in situations governed by asymmetric information. In this context, investors in reward-based crowdfunding platforms might modify their purchasing intentions according to recommendations of peers and/or experts. The goal of this paper is to analyze the power of eWOM to shape consumers’ purchasing decisions. We do so by conducting an experiment through Amazon Mechanical Turk (AMT). This online experimental tool allows for an instant access to a large and culturally diverse subject pool, facilitating behavioral research requiring large amounts of subjects. By recreating a reward-based crowdfunding webpage and tracking how consumers’ choices vary due to recommendations of other buyers and experts, this research confirms eWOM power in modifying purchasing decisions, as well as the prevalence of other buyers’ recommendations over those of experts. Additionally, it is tested AMT as a crowdsourcing platform that enables scholars to carry out online research related to economics and social sciences.
[en] The role of data management is one of the greatest contributions in the research workflow for scientific experiments such as neutron scattering. The facility is required to safely and efficiently manage a huge amount of data over the long duration, and provide an effective data access for facility users promoting the creation of scientific results. In order to meet these requirements, we are operating and updating a data management infrastructure in J-PAPC/MLF, which consists of the webbased integrated data management system called the MLF Experimental Database (MLF EXP-DB), the hierarchical raw data repository composed of distributed storages, and the integrated authentication system. The MLF EXP-DB creates experimental data catalogues in which raw data, measurement logs, and other contextual information on sample, experimental proposal, investigator, etc. are interrelated. This system conducts the reposition, archive and on-demand retrieve of raw data in the repository. Facility users are able to access the experimental data via a web portal. This contribution presents the overview of our data management infrastructure, and the recent updated features for high availability, scaling-out, and flexible data retrieval in the MLF EXP-DB.

[en] The International Network of Nuclear Reaction Data Centres (NRDC) constitutes a worldwide cooperation of 14 nuclear data centres. The main activity of the NRDC Network is collection and compilation of experimental nuclear reaction cross section data and the related bibliographic information in the EXFOR and CINDA databases as well as dissemination of nuclear reaction data and associated documentation to users. The database contains information and numerical data from more than about 19000 experiments consisting of more than 140000 datasets. EXFOR is kept up to date by constantly adding newly published experimental information. Tools developed for data dissemination utilise modern database technologies with fast online capabilities over the Internet. Users are provided with sophisticated search options, a user-friendly retrieval interface for downloading data in different formats, and additional output options such as improved data plotting capabilities. The present status of the EXFOR database will be presented together with the latest development for data access and retrieval. (authors)
[en] Licensees are implementing cyber security measures gradually to establish the system for the operating nuclear facilities, but some of measures are security requirements to be considered from the development phase of CDAs such as logical access control, log function, security design, security test, configuration management, supply chain control, and acceptance test. Applying the above security measures to CDAs that are already in operation can cause not only design changes and operation delay but also conflicts between safety and security such as affecting system reliability and safety functions. This paper suggests cyber security activities during the life-cycle including the development phase of CDAs. The regulatory standards of domestic cyber security and lessons learned from review experiences of constructing facilities are referenced, and the IAEA, IEC international guidelines on cyber security of digital I&C, and U.S. NRC Regulatory Guide are cited. Recently, as the NRC endorsed the NEI 13-10 on the graded approach for cyber security measures, this paper focuses on the cyber security activities for Direct CDAs during life-cycle, which many security measures are considered at the development phase. This paper suggests the cyber security activities during the life-cycle including the development phase of Direct CDAs. The nuclear cyber security should be systematically and effectively applied from the development phase considering the impact on system functions, the limitations on accessing and changing the system and spread of impacts. It is expected that CDAs can be protected through periodic assessments of the monitoring and robustness of implementation these security measures.
[en] The nuclear databases which have been developed at the Centre for Photonuclear Experiments Data of the D.V. Skobel'tsyn Scientific Research Institute for Nuclear Physics, M.V. Lomonosov Moscow State University, and put on the Centre's web server, are presented. The possibilities for working with these databases on the Internet are described. (author)
[en] The function of the search engine is to retrieve data from ENSDF-formatted files and to write data in user-selected format. The purposes are horizontal systematics of nuclear mass surface, comparison with experimental data and to assist in data analysis and evaluation
[en] We report here on a new Web-based version of the IAEA bibliographic database on atomic and molecular physics and plasma-material interaction. The existing bibliographic information from the telnet-accessible AMBDAS system was incorporated into a free-source object-relational database management system PostgreSQL v. 7.1.3 . The newly developed WWW interface to the database can be freely accessed at URL http://ww-amdis.iaea.org/AMBDAS/. This interface provides various search options over, e.g., author names, keywords, publication years, categories and processes, reactants and surfaces, ion charges, isoelectronic sequences, etc. Nested searches over author names are allowed as well. The data output contains direct links to the corresponding journal home pages to facilitate the access to the original sources of data. The numerical data on energy or temperature limits and types of reactants and surfaces is provided where available. The interface is self-explanatory, with help information available for the user. The AMBDAS presently contains about 40,000 references relevant to atomic, molecular and plasma-material-interaction data and is updated twice a year
