It becomes increasingly important to develop sustainable housing to protect environment. The certification system for long-life housing was made to use houses for more than one hundred years in 2014. The long-life housing should be able to meet new demands by change of the population structure; low birthrate, aging and increase of single households. Therefore, it is necessary to suggest a prototype of long-life housing for partial rent. The objective of this study is to suggest a prototype for dividing housing in the long-life validation complex, which has design consideration for dividable house. The construction costs of a prototype for dividing housing is evaluated by comparing with other prototype without regard to dividing housing. The results were as follows: (1) The prototype for diving housing should be added an entrance, bathroom, kitchen for tenant, and above all, maintenance fees for tenant have to be managed seperately from house owner. (2) The equipment system for dividing housing should be designed when planning the space of house. However, design for diving housing should be reflected the unit plan at a minimum on what will and will not happen.

Following natural disasters, there is a need to develop temporary housing through the rapid installation of mass-produced prefabricated housing. This study has developed a model construction manual for prefabricated temporary housing installable in underground spaces. First, the temporary housing prototype was drawn based on opinion poll results from earlier studies. $4.32m^2$ was calculated as the basic unit of the temporary housing living space for one person. Units included panel type, box type and mixed-type, for a variety of field conditions and scales. In order to enable space expansion and movement desirable to the user, the prototype was combination of panel and box types. The drawn prototype was utilized as the basic design template for producing prototypes and for the manual. Second, the possibility of utilizing subway stations as temporary housing was verified through the production of the prototype, and the construction process was summarized in the manual. The manual was developed in the form of a checklist to provide a guideline for users to build with prefab materials.

The tank uses a twin turbo diesel engine equipped with two turbocharger systems for high output. The main component of the turbocharger system is the turbine housing through which the exhaust flows. Turbine housing is manufactured through a sand casting process, taking into account the shape and material characteristics according to the environmental conditions in which it is used. Currently, turbine housing is imported, and local production is necessary. In this study, basic research was conducted to localize the turbine housing of a tank diesel turbo engine. Reverse engineering and finite element analysis of the imported turbine housing were performed. The prototype of the turbine housing was printed using FDM and PBF 3D printers. The prototype of the turbine housing printed with an FDM 3D printer has an overall appearance similar to 3D modeling, but the printed surface of the whorl part is rough. The prototype printed with the PBF 3D printer is completely identical to the 3D modeling, including the whorl part.

This paper describes the forming of fine gear housing using RP system. In order to apply 3D model formed through CAD software to RP system, it is necessary of transforming 3D model into STL file format. Besides, when the same shape is formed repetitively, we must solve the program that the shape accuracy of prototype is irregular. Therefore, we will make an experiment on influence of 3D model, file transformation and prototype on facetres, AutoCAD system value. On the basis of experimental result, we will develop an automatic file transformation program for RP. In the final process, we will manufacture on a better prototype according to the experiment result of fine gear housing.

In respond to the global energy crisis and climate change, there have been many ongoing national efforts to develop a sustainable housing prototype followed by "2 million Green Home Project" in Korea. More than 50% of nation's population are currently living in apartment housing thus the country is seriously in need of developing green apartment prototype. In this research, we focused on energy-conservative green apartment design prototype that have both passive components and active systems explored in a systemic design approach. After selecting an existing basic apartment unit, we analyzed and compared statistical data with the simulated annual energy consumption to match these two data sets for validating simulation accuracy performed with TRNSYS package. We performed energy simulations with different passive design factors such as varied insulation thickness, window types and infiltration rates as well as the active design factors including boilers and lighting fixtures to analyze their impacts on the energy performance of the housing unit using TRNSYS software. As a result, we acquired significant energy reduction effect with explored design strategies but the life cycle cost analysis for the final design guidline would need to be performed. In this study, we focused on a systematic comparative energy analysis based on TRNSYS that can improve the design of a green apartment housing.

The injector housing has two functions, namely, positioning the injector and protecting it from coolant. The conventional manufacturing process of the injector housing by machining has some drawbacks such as considerable loss of material and environmental pollution caused by excessive use of cutting oil. In this paper, precision cold forging is proposed as a new manufacturing process in order to improve these issues. A numerical study was conducted to compute the metal flow, strain, load and other process variables using DEFORM-2D, a finite element analysis(FEA) code for metal forming. Two process methods were investigated and optimal conditions were computed with the FEA code. A prototype was manufactured from the optimal process method and the metal flow and hardness were obtained from the prototype.

Disasters that destroy homes and infrastructure and cause significant financial damage are becoming more common as population centers grow. In addition, several natural disasters have resulted in a major loss of life and created countless refugees due to damage to housing. After major catastrophic disasters, it is very important that the government agencies respond to post-disaster housing issues and provide resources such as temporary housing before the full rehabilitation and reconstruction of destroyed and damaged housing. To provide affordable temporary housing for residents who may lose their homes as the result of a catastrophic disaster including storms, government agencies must develop a post-disaster housing prototype. In general, government agencies should explore several different forms of factory-built single-story, single family housing, such as modular homes, panelized homes, and precut homes. In urban cities including New York and Seoul, it is very important to provide housing which supports the demand for higher-density living spaces than single-family homes or trailers typically available due to the high population density and the desire to resettle as many residents as possible in their former neighborhoods. This study identified the urban post-disaster housing prototypes that may provide higher density housing with high quality living spaces, high air quality, and energy efficiency as well as rapid deployment. A case study of "Urban Post-Disaster Housing Prototype Program in New York" was conducted through a detailed interview process with a designer, engineer, contractor, the Office of Emergency Management (OEM) in New York, the U.S. Army Corps of Engineers (USACE), and temporary occupants. An appropriate disaster housing program that can provide living spaces for victims of disasters that keeps residents in their community and allows them to live and work in their neighborhoods was developed.

The Werkbund housing exhibitions in Europe in the 20's and 30's presented various planning concepts and played a important roll for modernization of housing Architecture. This study, therefore, aims to understand the contemporary issues of housing in this period, which showed the meaningful momentum for housing plans today. In order to grasp the general characteristics of exhibition housing the representative cases -Weissenhofsiedlung, Dammerstock, Breslausiedlung, Werkbund Siedlung in $Z\"{u}rich-Neub\"{u}hl$, Werkbundsiedlung Wien und BaBa- were throught documents analyzed. The architects offered an innovative building typology such as row housing and new prototype of housing units accordingly social needs. Especially, In this study housing unitplans were in 6 groups such as flexible type, cabin type, free open plan, Raumplan, functional 2-story type and corridor type categorized. And they were analyzed how deeply technological development, architectural design perceptions as well as functional aspects had on the planning of floorplans reflected. As a result, in the housing exhibitions various architectural ideas presented the "Zeitgeist" not only such as improvement of physical environment of housing, but also such as rationalization, standardization, functionalization, normalization of housing architecture. Also their unitplans corresponded to newly developed building typology and modern household type. As well as they represented notable spatial concepts. Moreover it contributed to create a new paradigm of housing for the new epoch.

This study explores the typology of the urban detached houses in the new housing quarters that were created in the process of Seoul's urbanization in the aftermath of the Korean War. It analyzes and compares the urban tissue and space allocation set when the new urban residential areas were organized according to different methods of production. Based on the comparative analysis of housing built in the same time of 1960s, this study aims to deduce why a specific urban detached housing type was selected as an influential housing prototype and how this spread in later generations. Case study sites selected for this study include: the new Urban Hanok towns of Yongdu-dong, filled with mass Urban Hanoks built by housing developers; the single-family detached housing district of Myunmok-dong, filled with individual dwellings built by private builders; and the housing complex of detached houses in Suyu-dong, developed by government-sponsorship during the early 1960s. Each case examines the following: first, the difference in housing typology allocation according to urban tissue; second, the difference in spatial composition and arrangement within plots. As a result, it was found that differences in typology occur depending on which of the social, cultural, economic and technical factors was preferentially considered in forming urban tissue and allocating buildings in each residential area.
