The objective of this study is to evaluate the human performance relating to the layouts of the two different hand switch types with two and three buttons in the nuclear power plants. Using a computer simulation, the cognitive performance for the hand switch layouts was measured on the basis of response and task completion times. Comparative analyses were performed with three different layouts representing the current switch arrangements in the Yonggwang nuclear plants 5 and 6 and Ulchin 3 and 4, respectively. Statistical analyses revealed that the performance of the two-buttoned switch layouts was found to be better than those of the three-buttoned switch. Furthermore, the superiority of the two-buttoned switch type is consistent regardless of various layout types. These results imply that the difference of the cognitive performance can be attributable to the switch types rather than to the switch layouts. Therefore, from the cognitive perspective, the two-buttoned switch type is recommended for future power nuclear plants.

With the development of cognitive science and environmental psychology, there have been growing researches and discussions on the relationship between the residential design preferences and personality types. MBTI personality types have been earning popular credibility. MBTI means Myers-Briggs Type Indicator. It is based on Carl Jung's theory of psychological type. This study is based on Myers-Briggs theory to explain residential furnishing preference and explores the relationship between the four bi-polar personality types-Extroversion/Introversion, Sensing/Intuition, Thinking/Perceiving and residential furnishing preference. These tests were conducted to two hundred and twelve adult residents who live in Seoul, Korea. These tests were analyzed several significances by Chi-Square with SPSS for windows software. (E) Extroverted residents prefer layouts for interaction with guests. (I) Introverted residents prefer centripetal layout around the bed. (S) Sensing residents prefer practical and functional layouts. (N) Intuitive residents prefer personal and conceiving layouts. (T) Thinking residents prefer for attribute of space. (F) Feeling residents for familiar conversation. (J) Judging residents prefer systematic and complete layouts. (P) Perceiving residents prefer adaptable and flexible layouts. In conclusion, personality types can have a determining role in preference of residential furnishing layouts. This study suggests that residential designers should take into account clients' personality types prefer effective designing and should provide a variety of alternatives reflecting clients' preferences. This will promote clients' pleasantness and satisfaction in dwelling at home.

The study intends to systematically arrange and classify the museum layouts in terms of their structure of exhibition space. The exhibition space, here, means the whole area where visitors are allowed to move and visit in museums. Through this, I tied to understand the characteristics and trends comparing and analyzing international and national exhibition space layout, and then grope the standard in case of establishing museum. The first criteria is based on the point of view that the typical museum experience is made in the exhibition space. Accordingly, the exhibition space can be grouped into two categories; one is 'room type' consisting mostly of individual rooms as in classical museums, and the other is 'open plan type' consisting free standing walls as in miesian free plan. The second criteria is dependent on the way how visitors move about in exhibition spaces. In other words, museum layouts can be categorized in terms of mutual connection between individual spaces including exhibition spaces and corridor spaces designated for the purpose of moving. consequently, the layouts can be categorized into five groups such as 'free plan', 'linear type', 'room to room', 'room & corridor' and 'composition type'. The third criteria is about the overall structure of museum layouts including such elements as whether it contains a certain type of central major space or not and whether and how the exhibition spaces are connected to it. By applying these classificatory criteria, the study analyzed and classified 90 sample of museum layouts in order to understand clearly and succintly the spatial characteristics and implications contained in them.

The purpose of this study is to scrutinize the effect of office layouts and ambient office sounds on the performance of office workers involved with a proof-reading test (simple task). Twenty subjects, who were professional researchers and computer programmers, were from three different office layouts: 1) Nine subjects from a combined office type with open meeting places and closed individual offices; 2) five from an open office with rectangular individual workstations, and 3) six from an open office with triangular individual workstations. Architects and consultants working in the field of office have reported from interviews and their own observations that occupants' satisfaction differs as their office layouts vary although the sizes are the same. This finding leads to the hypothesis of this experiment. Proof-reading test results were obtained from three different office layouts (combined office type, rectangular and triangular individual workstations in open offices) under two different sound conditions (quiet background sound and ambient sound of their own workplace) for 10 minutes. The test analysis shows the mean test score of subjects from the triangular individual workstations in open offices is significantly different from the mean test scores of subjects from the combined office type and the rectangular individual workstations in open offices.

A partition of water distribution network (WDN) into district metered areas (DMAs) brings the efficiency and efficacy for water network operation and management (O&M), especially in monitoring pressure and leakage. Traditionally, the DMA configurations (i.e., number, shape, and size of DMAs) are permanent and cannot be changed occasionally. This leads to changes in water quality and reduced network redundancy lowering network resilience against abnormal conditions such as water demand variability and mechanical failures. This study proposes a framework to automatically divide a WDN into dynamic DMA configurations, in which the DMA layouts can self-adapt in response to abnormal scenarios. To that aim, a complex graph theory is adopted to sectorize a WDN into multiscale DMA layouts. Then, different failure-based scenarios are investigated on the existing DMA layouts. Here, an optimization-based model is proposed to convert existing DMA layouts into dynamic layouts by considering existing valves and possibly placing new valves. The objective is to minimize the alteration of flow paths (i.e., flow direction and velocity in the pipes) while preserving the hydraulic performance of the network. The proposed method is tested on a real complex WDN for demonstration and validation of the approach.

A cable-stiffened cylindrical single-layer latticed shell that is reinforced by cable-stiffened system has superior stability behaviour compared with the ordinary cylindrical latticed shell. The layouts of cable-stiffened system are flexible in this structural system, and different layouts contribute different stiffness to the structure. However, the existed few research primarily focused on the simplest type of cable layouts, in which the grids of the latticed shell are diagonally stiffened by prestressed cables in-plane. This current work examines the stability behaviour of the cable-stiffened cylindrical latticed shells with two different types of cable layouts using nonlinear finite element analysis. A parametric study on the effect of cross-sectional of the cables, pretension in cables, joint stiffness, initial imperfections, load distributions and boundary conditions is presented. The findings are useful for the reference of the designer in using this type of structural system.

The objective of this research is to identify a web portal's specific functions and layouts that are aligned with personality trait of an individual internet user. This first stage of the overall research project intends to check whether the research instrument, namely the NEO Five Factors Inventory (NEO-FFI), is applicable to assess the personality traits of Thai internet users. Based on these personality traits, text-based description of functions/layouts of a web portal was developed and given to professional designers to mock up example web portal pages. These web portal pages were in alignment with individual personality traits. Rating data on the functions/layouts corresponding to individual personality traits were collected from an online survey of 207 Thai internet users. Results showed that respondents gave more consistent rating to the functions/layouts close to their individual personality traits identified in the text-based descriptions than in the mocked-up web portal pages.
