The paper proposes a multi-body dynamic simulation to numerically evaluate the generated axial force(G.A.F) and plunging resistant force(P.R.F) practically related to the shudder and idling vibration of an automobile. A numerical analysis of two plunging types of CV joints, tripod joint(TJ) and very low axial tripod joint(VTJ), is conducted using the commercial program DAFUL. User-defined subroutines of a friction model illustrating the contacted parts of the outboard and inboard joint are subsequently developed to overcome the numerical instability and improve the solution performance. The Coulomb friction effect is applied to describe the contact models of the lubricated parts in the rolling and sliding mechanisms. The numerical results, in accordance with the joint articulation angle variation, are validated with experimentation. The offset between spider and tulip housing is demonstrated to be the critical role in producing the 3rd order component of the axial force that potentially causes the noise and vibration in vehicle. The VTJ shows an excellent behavior for the shudder when compared with TJ. In addition, a flexible nonlinear contact analysis coupled with rigid multi-body dynamics is also performed to show the dynamic strength characteristics of the rollers, housing, and spider.

This study has examined layout of communal outdoor space and welfare facilities in the nation's very first senior apartment complex in Segok-dong, Gangnam-gu that has been developed by Seoul City. In order for this space to play a role as a center of communication: 1) A center space of community should be created at the point of intersection of main moving lines of pedestrians. 2) Hierarchical area should be set up between main moving lines of walking and communal outdoor space. 3) It should be designed in a way to reflect demands of seniors and be accommodated their activities and behaviors. 4) It should be functionally connected to local infrastructure facilities so that it can promote social exchanges among seniors. Points to be considered in welfare facilities: 1) They should be placed at the center of the complex to provide convenience to all seniors. 2) Area of senior citizen center should be subject to flexible legal regulation in light of the unique characteristics of the Complex. 3) in case that welfare facilities are installed in the same space, intermediate space is required to alleviate collision between private space and public space. 4) Senior assistance facilities should put more emphasis on running programs that make good use of the space than on securing the space itself.

This research was for the investigation and analysis of the illustration of modular construction application which is different use by each school facility since modular construction related examples are rare in domestic situation, and it has a limitation because of its being basic research material for generating the basic form of modular construction. The research results are as followings. First, in case of school facility from illustration investigation results, module measurement of class modulation is as similar as $3m{\times}10m$, but in resident facility the planning of more flexible plane shape can be possible since modules of 6 cases are free and various, and facade form of various types can be appeared by combination of module unit. Second, as a result of the generated characteristics in compared analysis of representative examples, school facilities were highly indicated for movability and duration reduction areas, and the flexibility, economic efficiency, and environment-friendliness was indicated low relatively. Third, the basic planning types of modular construction can be largely divided into layered type, horizontal (straightway) type, and compound type. The layered type has a short traffic line and facility system and is appropriate for the low-rise form unless separate construction method is used since it is susceptible to load. The horizontal type is advantageous for securing an opening since it has wide extent in light but has a long traffic line and facility system. Finally, the compound type can be possible for planning of various forms but needs the combination of various unit modules and traffic line and facility plan for it can be difficult.

연구의 배경은 농촌주택이 도시주택의 공간구성을 모방하면서 원래의 모습을 잃어버리고 있기 때문이다. 이에 본 연구는 농촌주택표준설계도에 크리스토퍼 안렉산더의 패턴언어를 적용하여 농촌주택에 필요한 디자인 구성 요소를 추출하는 것을 목적으로 한다. 연구 범위와 방법은 한국 농어촌공사에서 2009년에서 2014년까지 제작 배포하고 있는 표준설계도에 패턴언어에서 제시하고 있는 디자인 패턴을 적용하여 비교 분석하는 것이다. 연구결과는 1) 표준설계도에서 주택배치는 다양한 농촌의 부지 조건을 무시하고 있었고. 2) 대부분 주택마당은 농촌생활의 다양한 행위를 담을 있는 공간임을 고려하여 적극적으로 계획하지 않았다. 3) 표준설계도는 어린이를 위한 공간이 없었고 부엌은 L.D.K 형식으로 내부공간을 통합하여 융통성 있는 공간으로 사용할 수 있도록 계획하였다. 4) 귀촌 귀농민을 위한 임대 가능한 별채와 사무공간으로 겸용할 수 있는 공간계획은 없었다. 5) 2014년에는 부부만을 위한 표준설계도 계획으로 면적이 좁은 평면계획이 많이 이루어졌다. 이와 같이 표준주택설계도에서 농촌의 환경과 생활 패턴이 무시된 부분도 있었지만, 패턴언어에서 제시하고 있는 다양한 패턴언어를 농촌주택의 표준 디자인 구성요소로 개발하여 귀촌 귀농민을 유입하고 농민들의 생활패턴에 가장 적합한 주택으로 개발할 수 있는 방안모색이 필요할 것으로 판단된다.

First of all, the multi-story Housing applying resident's participation in europe was classified by the menu selection method, the two-step supply method and the cooperative method. And then I analyzed flexible unit plan of cases for deriving the planning methode and the characteristics of flexibility. First, I analyzed the area and form of the unit plan, structure and Installation, fixed and variable elements to derive the planning method. The area of units are distributed from a minimum of $35m^2$ to a maximum of $150m^2$, and many of the unit planes have a narrow front and a deep depth. The structure is a long-span wall-structure or a skeleton structure, and is designed without any columns and bearing walls in the interior space for flexibility in spatial composition. The vertical shafts are located in the center of the unit in a box-form or in the corner at the unit dividing wall for free placement of interior wall. Fixed elements are framework and facility systems. Most of the future residents in the two-steps supply method and the cooperative method were able to freely design the internal space within the zoning concept proposed by the architect and change the location of the facade element within module system proposed by the architect. Second, the characteristics of the flexibility applied to the unit plan were divided in integrated flexibility, functional flexibility, construction flexibility, and supply flexibility. The integrated flexibility enables residents to give the variable space combination based on the complex structure of the inner space for providing various living experiences. Regarding functional flexibility, the three-dimensional spatial structure with neutral space has multi-functionality according to the needs of residents and easily accepts mixing of hybrid programs such as work and residence. Constructive flexibility allows residents to create identity by freely planning interior space and changing the size or location of facade components in a determined system of architects. Finally, various types of size and space composition are proposed and realized in the whole building applying menu selection method, so that flexibility in the offer can accommodate and integrate various types of living.

This study derives the characteristics of the private external space planning in multi-family housing through the analysis of the good case built after 2000 in Europe. First, the cases were categorized into block or block perimeter, linear and point type to examine the relationship between the type of building in urban context and the location of private external space. By block or block perimeter and linear type, private external spaces are planned in the inner courtyards or open space between buildings used as common space for residents, inducing communications between neighbors. And the direction of private external space depends on the arrangement of the building mass in urban context. In the classification as point type, there are many cases, where private external spaces are arranged in all directions, connected almost all interior spaces. Second, based on the above results, the planned characteristics of the private external space are derived by dividing it into three categories: intermediated space between inside and outside, intermediate space between private and public /individual and collective space and the identity of the intermediate space. (1) In most cases, direction, size of enclosed area and location of private extern space is designed to fit the surrounding context, so residents can perceive as much of the assets of the surrounding environment as possible, and it can be used as an extended area of living space. In another cases, it is divided into various sub-areas to experience the spatial transition from inside to outside or vice versa. 2) The private external space, which is placed in a courtyard or in a collective open space, is partially enclosed and blocked, allowing interaction with the neighbors without pressure. Along the street, they are designed to allow residents to experience the vitality of the city and to be formative element of the facade, which could confidently reveal the lifestyle and taste of residents. 3) By some of point types, which facade is three-demensional layer as a habitable external space, the private external space is very flexible for use. This intermediate space is composed of diverse spaces for various needs, or it has generous size with positional conditions connected with all interior spaces to be used multi-functional.
