One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators), Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps. Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training. When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.

With the increase of tall building construction, efforts for enhancing constructability are required from the pre-construction stage. Therefore, in this study, we proposed an evaluation method of constructability performance by performing construction engineering activities at the design phase. Based on some results of previous studies, we estimated the importance of design factors and categories influencing the constructability in each engineering activity related to temporary work and then presented a method for evaluating the constructability performance of design alternatives.

The dynamic performances of railway vehicles, such as ride comfort, stability and safety, have the opposite characteristics of response each other according to design changes of suspensions. For this reasons, it is necessary that multidisciplinary engineers join in design processes of the suspensions so as to satisfy the requirements of dynamic performance with design constraints. Sometimes iterative dynamic analyses are required so many times during the design processes. In this paper, the development of integrated process environments and the dynamic analyses of railway vehicles based on the environments are presented. Using agent and wrapping technologies, process managements about the work process and design parameters were set up under the distributed computing environments. Also, dynamic analyses on the sample railway vehicle were carried out and the efficiency and improvement in future work were discussed as results.

The purpose of this study was to develop and evaluate working clothes for shipbuilding workers who work in one of the poorest work environments among national strategic industries that are playing pivotal roles for the Korean economy. For the study method, requirements collected through interviews and field surveys were incorporated to directly weave the fabrics for working clothes. The colors were then selected and the woven fabrics were dyed with the selected colors. Using these, the designs of working clothes were planned from the construction and design aspects and four winter clothes and four spring and fall clothes were produced. Afterwards, the workers dressed in these clothes and workers and managers evaluated them in terms of appearance, color satisfaction, design satisfaction, and safety mind harmony on a five point scale. This study found that the new working clothes offered better functionality, design, and safety compared to existing working clothes.

Recent trends in rail industry can be characterized by the multifunctionality and very high-speed modes of operations. In particular, the adoption of the unmaned or operatorless operations has been getting increased attention in which case ensuring systems safety is crucial. On the other hand, according to the result of analyzing rail accidents, the human/operator errors have turned out to be one of the key causes of the accidents. Therefore, the effort of improving the work environment of locomotive cabs is quite necessary in order to decrease the accidents. The objective of this paper is studying on how to incorporate the factors related to the train operators in the design of the locomotive cabs and also on how to evaluate the design results obtained, which is subsequently reflected in the generation of the test and evaluation procedure. The approach taken is based on systems engineering, yielding the procedure document as a result. The results obtained in the paper can be useful in confirming the design of locomotive cabs utilizing the domestic human/operator measure. Also, the way of achieving the objectives can be utilized to cover the expanded rail systems development with appropriate design activities added.

This study aims to contribute to better understanding of the Baroque architect Francesco Borromini, and, as a consequence, of the Baroque period itself. Recognizing that historical studies have focused mainly on the architectural (i.e., formal) aspects of Borromini's work and largely neglected the technical (i.e., structural) issues, and that the relationship between the architectural and structural worlds in Borromini's activity has consequently never been studied in depth, this research set as its objective the study of this relationship, and has developed a comparative analysis of Borromini's attitude toward architectural problems and questions of tectonics. The investigation has been conducted on two meaningful case-studies in Rome: San Carlo alle Quattro Fontane and Sant'Ivo alla Sapienza. The analysis has highlighted a strong dichotomy between Borromini as an architectural designer and Borromini as a structural designer. While Borromini's design is experimental, innovative, and nonconformist, his structures are cautious, tested, and validated by trustworthy tradition. His unprejudiced use of constructive solutions from different historical periods, regions, and cultural areas allows the definition of his approach to tectonics as "constructive eclecticism." The analysis has also highlighted the independence between the architectural and structural aspects of his work, as the two do not interfere with or limit each other. The dichotomy between form and structure in Borromini's work may reflect the "theatrical" tendency of Baroque culture, where what is shown on the face is often different from what is hidden behind.

A nonlinear static procedure considering work-energy principle and global failure mechanism to estimate base shears of reinforced concrete (RC) frame-type structures is presented. The relative energy equation comprising of elastic vibrational energy, plastic strain energy and seismic input energy is obtained. The input energy is modified with a factor depending on damping ratio and ductility, and the energy that contributes to damage is obtained. The plastic energy is decreased with a factor to consider the reduced hysteretic behavior of RC members. Given the pre-selected failure mechanism, the modified energy balance equality is written using various approximations for modification factors of input energy and plastic energy in scientific literature. External work done by the design lateral forces distributed to story levels in accordance with Turkish Seismic Design Code is calculated considering the target plastic drift. Equating the plastic energy obtained from energy balance to external work done by the equivalent inertia forces considering, a total of 16 energy-based base shears for each frame are derived considering different combinations of modification factors. Ductility related parameters of modification factors are determined from pushover analysis. Relative input energy of multi degree of freedom (MDOF) system is approximated by using the modal-energy-decomposition approach. Energy-based design base shears are compared with those obtained from nonlinear time history (NLTH) analysis using recorded accelerograms. It is found that some of the energy-based base shears are in reasonable agreement with the mean base shear obtained from NLTH analysis.

The historical separation between organization studies and architecture area created a design environment in which wort processes are evaluated separately from setting where they occur. The impact of separation has been parallel yet disconnected development in th two disciplines in which the advance in one arena have not precipitated advances in the other. This is the unfortunate loss as each discipline has the potential to contribute directly to the other. With the emergence of new economy the opportunity to realign the tow disciplines is once again presented as new ways of working have enhanced this opportunity. It is important to revisit the historical development of the tow disciplines and to discuss how the misalignment of their respective concerns contributed to the establishment of our current situation. What happened to create an environment in which organizations assume that one of their largest capital expenditures the cost of providing work spaces for employees is unrelated to their work process\ulcorner what recent developments offer opportunities to rectify this dilemma\ulcorner In this study it is presented a historical review of organization studies and architecture. Through examination of these areas across time it becomes quite apparent that it is now appropriate to pose new questions about organization and their architecture. The comparison of two parallel developments explains how the current design environment is separated from organization studies and offers compelling evidence for why it is important to revisit this separation in light of contemporary theories on collaborative work, organizational learning and communities of practice.

The cooperation with other work types and designing procedure in plant industry and engineering showed clear differences from general construction industries. Current problems are that design's consistency is reduced because of the false system of interface and it ultimately causes frequency changes of design and delayed submission of final book. To solve the problems, the improvements of designing procedure were studied by focusing on the field of architectural designing and the range was limited from power plant construction industry to engineering designing field. If combining GA with the field of architectural designing and receiving data previously, it's possible to conduct expectable designing on small changes in the future, so it's expected to improve greatly cooperation with interface among the work types of power plant engineering received previously from the aspect of consistency. For the application of designing tool, a checklist, interim check will be conducted if progressed by list's division in the designing procedure, not book's completing period. In the interface among the designing work types, direct confirmation and revision must be conducted. In case of 3D modeling, the reflection of input data must be conducted from the basic designing so as to solve interferences intensively.
