The purpose of this study is to make planning factors for outdoor space in elementary school site, with analyzation focusing on a Japanese elementary school examples. We evaluated the planning factors which encourage the development of children’s behaviors from quality of space. And we can get the important points as planning factor for school site as follows: 1) The base point of zoning is school building, building entrance, entrance of site and track 2) The importance of linked space plan with inside of site and surrounding environment 3) Preservation linked system of space in school site for linked pattern of child’s behavior.

The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

This paper analyzes repairing methods in terms of symptoms of hard disk through maker's knowhow and skill from experience. However, though an user tries this method, if the user is not skilled person, it can be failed. A defect Hard disk should be diagnosed and treated carefully. And also it should be executed after enough practice. This analyzation was tried by examination with the naked eye, sound, and the frequency of symptoms. And the result can be precious data for restoration of critical evidence.

In IoT(Internet of Things) environment, users want to receive customized service by users' personal device such as smart watch and pendant. To fulfill this requirement, the mobile device should support a lot of functions. However, the miniaturization of mobile devices is another requirement and has limitation such as tiny display. limited I/O, and less powerful processors. To solve this limitation problem and provide customized service to users, this paper proposes a collaboration system for sharing various computing resources. The paper also proposes the method for reasoning and recommending suitable resources to compose the user-requested service in small device with limited power on expected time. For this goal, our system adopts MBTI(Myers-Briggs Type Indicator) to analyzes user's behavior pattern and recommends personalized resources based on the result of the analyzation. The evaluation in this paper shows that our approach not only reduces recommendation time but also increases user satisfaction with the result of recommendation.

Although porous concrete is resently used as a pavement at a parking lot, a public squre and a bicycle road, we use without enough examining. most the maintenance of quality for porous concrete is only dealt with strength and color tone. also, there is not yet enough fundamental data about dynamical properties for strength, rate of void and water permeability. even when it is applied to at the scene, it is been a matter. Accodingly in this study analyzed influences through the dynamical properties, combination, and time to vibration. After the analyzation, they investigated peculiar dynamics which are strength of porous concrete, rate of void, and water permeability follow the rate of increase on an admixture making pozzolan reaction. This is purpose to improve capacity of the sidewalk permeable concrete and development of the economical technique for pavement.

Insulation diagnosis techniques of power equipments for the stable power supply and prevention from accidents are of high importance. Diagnosis techniques is able to prevent from large accidents before they happen by finding signs of the accidents. From this point of view, this paper simulated discharge progress and partial discharge using needle-plan electrode system in air, studied the distribution of frequency spectrum of the radiated electromagnetic waves using biconical antenna and spectrum analyzer. From results of this study, the new method was introduced for measurement and analyzation of the radiated electromagnetic waves in accordance with discharge progress in air, Besides, according to the consideration of the mutual relation between frequency spectrum of the radiated electromagnetic waves and discharge progress, it was confirmed that detecting partial discharge and estimating discharge progress were possible.

The pulsation of a reciprocating type hydrogen compressor is occurred from the mechanism and this pulsation makes much noise and vibration. To reduce this pulsation, snubber is usually installed on that. To maintain the efficiency in the reciprocating type hydrogen compressor, the pulsation and vibration should be reduced. so it is necessary to research about the characteristic of pulsation and vibration. Therefore in this paper, the vibration characteristic of the snubber is analyzed in the base of optimized modeling condition through the flowing analysis of existing snubber. The prototype of reciprocating type hydrogen compressor is analyzed with numerical analysis. And making sure the present condition of hydrogen compressor through measurement of vibration and noise, and then it is established that the vibration characteristic data base on numerical analysis which will be develope.

This paper is a study on the 'primitivism' which is constantly being applied on modem and contemporary textile design as a aItanative expression of the serious environmental phenomena of materialism. Starting with the analyzation of the 'concept of primitivism' , this paper is to research the 'origin of primitivism' which was first recognized by the modem artists. Primitivism on modem textile design will be suggested through 'trend terms'. The purpose of this paper is to be a basic material source for the creative development in design as well as to be of help in development of theoretical the study on contemporary textile design.

On this research, recognizing that ship inspection and audit services are closely related in Improving ship safety, the importance of active quality managements of ship inspection and audit services have been notified. For this research, based on previous research results, Quality managements of ship inspection and audit services were divided into the following aspects; the source of quality managements, execution of quality managements and outcome of quality managements. The results of this study is as follows. Overall, it is clearly shown that the elements of quality managements execution such as management responsibilities, resource management., product realization, measurement and analyzation, and improvement had also acted as a mediator between the relation of quality managements source and outcome.

It shows not only positive effect with fan as a way of improving condition in workplace but also shows air supply, ventilation condition in welding site with CFD analyzation. Also when the wind blew to the front side by a fan, the welding Hume significantly reduced, As this was examined as CFD and was gone through enough exhaustion to become streamline flow laminar, the toxic materials will be reduced. The improvement of welding work and education are investigated to be more significant factors than wearing protective equipments and setting safety tools to prevent welding works from welding fume exposure.
