General operation means NPP start-up and shut down operation, and it is one of the most important NPP operation manners. It is necessary to design a general operation strategy and related procedures for those advanced Gen III PWR reactor because of their innovative design features. By applying function analysis and task analysis technology, and considering the innovative design features, this paper carries out a hypothetical advanced PWR (HAP) general operation strategy design work with a systematical method. It is indicated that this method is able to be used in the general operation strategy design of other new type advanced reactors efficiently and accurately as a common method.

Nuclear Power Plants (NPP) have multiple levels of defense in depth hierarchy. The NPP accident condition operation strategy belongs to the 3rd level. It is used to supervise the operator to handle the NPP under accident operating condition. NPP accident condition operation strategy is an essential and difficult work in NPP design field, hence only few organizations are able to develop the accident operating strategies independently all over the world. In this paper, a systematic NPP accident operating condition strategy design methodology is raised based on function analysis and task analysis technology. Based on the methodology, a reactivity accident operation strategy is designed and proved to be reasonable through preliminary verification and validation work.

Purpose The purpose of this paper is to identify the main features of smart work centers (SWCs) and show how these innovative offices would support the implementation of smart working and related changes in workspaces (“bricks”), technologies (“bytes”) and organizational practices (“behaviors”). Design/methodology/approach In this study, scientific literature is combined with white papers and business reports and visits to 14 workplaces, including offices designed as SWCs, co-working spaces, one telecenter, one accelerator and one fab lab. Primary data were collected through interviews with managers and users and non-participant observation, whereas secondary data included web-sites, brochures, presentations, press releases and official documents. Findings The authors developed research propositions about how the design of spaces and the availability of technology within SWCs would support the “bricks” and “bytes” levers of smart working. More importantly, the authors assumed that this new type of workplace would sustain changes in employees’ behaviors and managers’ practices, thus helping to overcome several challenges traditionally associated with remote working. Research limitations/implications The exploratory nature of the research only provides preliminary information about the role of SWCs within smart working programs. Additional qualitative and quantitative empirical investigation is required. Practical implications This study provides valuable knowledge about how the design of corporate offices can be leveraged to sustain the implementation of smart working. Originality/value This study advances knowledge on workplaces by focusing on an innovative design of traditional offices (SWC). It also lays the foundations for future investigation aimed at testing the developed propositions.

Abstract Classification of System, Component and Structure (SSC) is the base as well as high level demand of nuclear power plant. Equipment classification including electric and Instrument and Control (I&C) equipment is the precondition of correct design regulation and standard. Safety function classification is key pass of electric and I&C equipment classification. This paper researches the method of nuclear power plant electric and I&C equipment safety function classification. Firstly from view of function, it explains the importance of function classification. Then function analysis and classification of equipment is implemented by design order. Lastly from view of accident analysis, function classification is validated, and a complete approach of function classification is formed. The purpose of this paper is the NPP electric and I&C equipment safety function classification as an example, to study and summarize the method of the electric and I&C equipment safety function classification, and to provide the basis for specific items design work according to design requirements. At the same time, a practical method is provided for other similar NPP electric and I&C equipment classification work. The electric and I&C equipment function classification of nuclear power plant satisfy the basic principles requirement of relative nuclear power rules and codes. It provides an important basis of equipment classification for next nuclear power plants.

ABSTRACTThis study investigated subgroup and task specificity of self-paced timing in children with developmental coordination disorder (DCD). Self-paced tempo (intertap interval) and timing stability (coefficient of variation) were measured in three repetitive tasks—hand tapping, foot tapping, and jumping in place—in 37 children aged 6 to 9 years classified into gross motor impaired (GM), fine and gross motor impaired (F&G), or coordinated control (CC) groups. Results showed that, although tempo did not vary between coordination groups, timing stability for the hand was significantly worse for the F&G motor impaired group (p < .05). Discriminant function analysis correctly classified 75% of CC, 67% of F&G, and 67% of GM children. Although timing inconsistency of hand tapping identified a coordination subgroup, these tasks provide only moderate prediction of group membership.

Architectural Organization

In the late 1990s on the market of high-quality real estate in Russia became popular a luxury apartment building called "club house". However, frequently the proposed design solutions do not meet the requirements for the architectural organization of this class dwelling. The aim of the research is to determine the optimal architectural and planning parameters of "club houses", identified on the basis of the analysis of the project implementations experience.The prerequisite for the appearance of such objects was the decision of the Moscow government to ban the construction of multi-storey houses in the historic center of the capital. To build in the center the usual multi-storey houses for the mass consumer was not correct. The solution of this problem was proposed by developers – an elite low-apartment house, built or renovated on an exclusive project in a prestigious landscaped area for a narrow circle of residents belonging to the same social class and having a high material and property level. The new type of housing immediately interested wealthy citizens.
