The purpose of this study is to describe the planning and applied safety facility layout for a technology laboratory in a middle school. A technological teaching facility has its essential purpose in meeting students' needs and achieving educational objectives efficiently and effectively. Practice-related appliances were selected through investigation of the current middle school laboratory, and analysis of the technology textbooks of the 7th curriculum. Laboratory layout was achieved with consideration of the teacher's and students need of safety and close proximity to laboratory facilities and equipment. Our recommendation takes the SLP survey results into consideration. The results of this study are as follows: The following floor plan is recommended. The facility layout will insure that students are able to work safely, in full view of academic instructors. Students will have easy access to all equipment due to the efficient floor plan and logical sequencing of equipment.

In the present work, Taguchi method for electron beam welding(EBW) process in AISI 4130 steel plate has been adopted for investigating the contribution of effect of welding variables. $A L_8(2^7)$ orthogonal array is adopted to obtain the effect of adjustment parameters. The adjustment parameters consist of accelerating voltage, beam current, travel speed and focus currrent. And the quality features selected for the EBW process are bead width of weldment, reinforcement, penetration depth, undercut and area of weld metal. Variance analysis is performed in order to check the effect of adjustment parameters on EBW. The mechanical properties of electron beam welded joints for each heat treatment conditions are investigated in comparison with those of base metal, especially from the view point of tensile and impact properties.

A syudy on hospital architecture was as a circulation effective work as most amount and function at the view of nurse, staff until now. The architect do not have a data about planning patient-centered hospital, do not reflect a demand of patient at the planning step. This study arrange what is concept of patient-centered, recently concept of patient-centered hospital is importantly raised, at centering around a ward that a life of patient is the most influenced. This study make clear character of patient-centered hospital at home, the problem and demand of patient through the P.O.E.

Higher productivity and less cost during the manufacturing process of ships are required to maintain international competitiveness of modern shipbuilding industries. The integrated hull/ outfitting/ painting scheduling(IHOP) process is a final point, where logistics are finally being integrated and upcoming schedules are made. Therefore, more profits are expected from IHOP by effective management. In this thesis, IHOP is proposed in order to solve how to choose block erection date with IHOP scheduling logic. The result of IHOP scheduling is highly advised to utilize fabrication, outfitting shops. A standardized operation and load of resource will eventually be applied in long-term time span point of view for this will make it easy to enable capacity planning and workforce planning. It is also expected to eliminate inefficiency in overtime work and efficiently utilize manpower in short-term.

This study is on the aesthetic characteristics of Balenciaga design succeeded to by Nicolas Ghesquiere, and tried to understand his pursuing brand's new design concept and aesthetics. The three key characteristics of Balenciaga designed by Nicolas Ghesquiere are Retrospecitvness, Eclecticism, Deconstruciton. First, Balenciaga looks retrospective sense through reinterpreting tradition. Nicolas created a new sense of expression by mixing his proper instinct with Balenciaga's original properties, historical components of the past western dress, and various design elements of assistants who used to work in Balenciaga. Second, Balenciaga expresses uncertain meaning by compromising between contrast and synthesis among the past and the future, the males and the females, simple and ornament, or different styles. Third, Nicolas's experimental and outsider-oriented view of Deconstruction through reorienting of thought is considered a try for a new formative concept as a designer who is not limited by general rules.

Particles reinforced MMCs have higher specific modulus, higher specific strength, better properties at elevated temperatures and better wear resistance than monolithic metals. But the coefficient of thermal expansion(CTE) of Al6061 is 5 times larger than that of SiCp. The discrepancy of CTE makes some residual stresses inside of MMCs. This work investigates Si$C_p$/Al6061 composites at high temperatures in the microscopic view by three-dimensional elasto-plastic finite element analyses and compares the analytical results with the experimental ones. The theoretical model is not able to consider the nonuniform shape of particle. So the shape of particle is assumed to be perfect global shape. And also particle distribution is not homogeneous in experimental specimen. It is assumed to be homogeneous in simulation model. The type of particle distribution is face-centered cubic array(FCC array). Furthermore, non-homogeneous distribution is modeled by combination of several volume fractions.

The value of 21 century travel originnate from increasing hate about environment pollution and contirmation of quality of life. Therefore the role of travel industry will developo into travel industry that travel information and knowledge unite with service under computer Reservation system out of basic travel work(counsel, agency, mediation, service, sale) So, a view of the travel industry that it is as following. 1. Operrating CRS of travel industry. 2. Constantly development of travel product and service. 2. Constantly development of travel product and service. 3. Pursuide to humanity and nature 4. Travel for keeping natural environment. 5. Establishment of new travel law. In conclusion, we certity our lappiness through travel and create new travel culture.

This paper presents an analysis of wind velocity and pressure data obtained in a rural environment with a view to identifying the vortex structures present within the flow and examining the relationship between pressure and dynamic pressure. The data is analysed using both conventional analysis and conditional sampling. A method examining the eigenvalues of a matrix formed by the addition of the square of the strain tensor and the square of the vorticity tensor is also investigated. This method illustrates that there are a number of vortex structures present in the flow. The work presented in this paper suggests that the extreme events occur as a result of the superposition of two independent mechanisms.

Accurate simulation of jet plume exhausting into the open space as well as onto the opposing wall is of interest both numerically and physically; the latter, from a system designer's point of view. In the current work, Navier-Stokes computation is undertaken to capture the flow pattern of a supersonic jet impinging onto a rectangular duct which deflects the vertical jet horizontally. Of particular interest are the flow structure in the jet exhaust area, pressure pattern and the magnitude of pressure force at the bottom wall. Usefulness of present characteristic boundary condition applied at the exiting plane of the duct is demonstrated by capturing such complex flow structures for different lengths of the deflection duct.

One of the eventual goals of VR research is to provide valuable experiences to the participants. In this work, we view that the content of experience is composed of a sequence of events, and develop algorithms authoring those events. Event authoring can be realized by controlling agents in VE in two different modes: (1) the autonomous mode, in which the agent exhibit autonomous behaviors based on the current world status and its own personality, and (2) the event mode, in which the behaviors generated form the autonomous mode is further controlled to meet the needs of the experiment. We define the event authoring language, so that the authors can design experiments by writing event-programs. Then the architecture of event execution manager is described, which is the heart of event-program execution. prove the effectiveness of our approach by showing results of several experiments.
