Experimental research was undertaken to develop a domestic spray nozzle used on equipment for desalination. First, we made a test set-up in order to confirm nozzle efficiency of spray and distribution under different pressure conditions. Then, we found a maximum spray condition after verifying reliability of this facility. An optimum arrangement of the nozzle, based on the test result, was made using CATIA V5 and EXCEL.

This study was executed by means of "user participatory design method", as a part of the public facility remodelling project supervised by the Seoul Municipality. This study aimed to complement and improve the methodology through reviewing the whole process of participatory design implementation and examining closely whether the activities, design methods and tools that have been applied at each stage were helpful to reflect the users' demands successfully. Given all of those, it implies; first, it is very meaningful that public facility remodelling project by "user participatory design" leads the ordinary users to have direct opportunity to participate in the public business and to change their perception of the restroom environment in school. Second, it is necessary to integrate the roles of the facilitator and the architect from the beginning stage of the process, which makes it feasible to reflect the users' needs to the final stage. Third, it is required to modify the design tools that enable non-professional participants to understand their tasks and to perform them effectively at the stage of decision making.

This study is to investigate the possibility of legislation that is the foundation of school complexation project and the architectural planning for the target facility as stipulated by related law. Since 2000, many schools have been established and operated in the whole of Korea, mainly in Seoul. However, on the frontline, there is still a lot of difficulty in carrying out the project due to the legal possibility related to the school complexation and the lack of understanding about the facility for school complexation as stipulated by the law. The purpose of this study is to present the possibility of the school complexation project based on related laws and to clarify the classifications of school complexation facilities which are stipulated by the related law, and to propose the foundation for the future school complexation project. The contents of this study were investigated through the literature survey on the theoretical review and related laws of school complexation, and various laws related to school complexation were classified based on this, and the possibility of school complexification prescribed by each law was analyzed. In addition, by classifying facilities subject to school complexation prescribed by the Act and analyzing the detailed standards stipulated in relevant laws for each facility, we propose the facilities that can be combined with school facilities, and utilize the data of this study.

Global environment is getting deteriorated at an alarming rate. Eco-school could be one of the effective solutions to project our environment and a good sample of architecture to economize in total energies, resources and greenhouse gases. In case of our country, the study of eco-school planning is not sufficient compared with other countries, so this paper would be a good study on the indoor environment of the classroom by surveying their opinions and ideas from the group of users in school facility. The result of this study shows that the proper installation of building equipment and nature ventilation system is necessary to provide delightful environment for the students and to save the energy. To ensure that we have adequate saving and protection it is necessary to change the existing appraisal standard.

The intent of this study is to investigate the current situations and planning implications of elementary schools in urban housing blocks, and to propose the planning and design guidelines for them. The premise of this research is that an elementary school should function as a communal facility, shared by its community, so called open-school. 32 schools in three new towns were selected as sample cases and they were closely surveyed in terms of their site planning issues in residential blocks, and three sample open-elementary schools were analyzed in a comparative manner for finding their roles and functional fulfillment as a communal facility in the neighborhoods. Based on the findings, several planning principles and design techniques or devices are suggested for the utilization of elementary schools by local residents, mainly making issues of location, relationship to other facilities and open spaces in residential blocks, access, apartment layout, school building and outdoor spaces, and open program.

The purpose of this study is to analyze the 'Sant'Elia Nursery School' constructed in 1937 at Como, Italy. Giuseppe Terragni(1904-1943) is, as it well known, one of the representative architects in the period of Italian rationalism architecture. In particular, his 'Casa del Fascio(1928~1936)' is evaluated as a representative work of this period. The research is based on the original drawings and letters, mostly produced by G. Terragni himself. Through the analyze on the design process, the research tries to reveal Terragni's design method and strategy, especially in the educational facility project. There are at least four deferent phases in the Terragni's design process; in each phase, there are fundamental changes such as a structural grid system, relationships between skin and columns or spatial sequences. Establishment of a new guideline on the educational facility in 1925 is also an another important issue. There was a political need, during the period of Mussolini's regime, to find a model of educational facilities. So, this project reflects not only the Terragni's design process but also the good example of educational facility in the early Twenty Century in Europe.

It is important thing that air quality affects human health. And It is more important thing that Indoor Air Quality more affects human health than Outdoor Air Quality. The cause of that is indoor air pollutants are more absorbed than outdoor air pollutants. By the way, in case of Multi-use facility for example office, department store, school etc., it has a feature that there are more people than any other buildings. therethrough, effects of Indoor Air Quality of Multi-use facility affect more people's health than Indoor Air Quality of any other buildings. However, in multi-use facility, specifically retail store, chemical treated materials are used for interior finishing, showcase finishing and product finishing because esthetic element is more added for detention of customer. Consequently, in place where demands brisk sales, possibility that indoor air is polluted by VOCs is high. This study considered retail store's Indoor Air Quality. as result of experiment, figure of department store's air pollution exceed about 5~20 times in guideline of multi-use facility's Indoor Air Quality in any kind of shop of department store (guideline : $500{\mu}g/m^3$).

Facility management is to maintain and develop the primary structural, functional, aesthetic performance of facility in order to guaranty the users' daily convenience and safety. However it is hard to maintain and serve their intended function and safe environment from the beginning as times go by. As present educational government of city and local area has been performing formally facility check and management as well as maintenance of school facility, it is hard to respond a dangerous situation at the suitable time and safety prevention plans are delayed. In addition, educational environment improving budget have been unreasonably decided not according to the allocating criteria. Therefore, this research developed a same, simple, and quantitative evaluation method of deterioration level of elementary, middle, and high School in Korea and verified usability of the method through the case study.

A high altitude test facility which includes supersonic diffuser and ejector has been developed to simulate atmospheric pressure at 25 km using a 500 N class small scale liquid rocket engine. Also high altitude simulation test for the small scale liquid rocket engine was performed to verify the facility's performance. The experimental facility consists of high altitude simulation device, propellants supply system and coolant supply system. Low pressure condition corresponding to about 27 km(0.021 bar) altitude atmosphere was successfully simulated and a small scale liquid rocket engine thrust level was confirmed at the simulated condition by the high altitude test facility verification test.
