The objective of this study is to apply the modular furniture system, which has been developed actively in western Europe and America since 1970's, to Korean contemporary furniture having converted into western style gradually. The factors requiring the modular furniture system in today's residential environment are as follows; 1. Population increase and urbanization 2. Development of industrial technology 3. Improvement of living condition and change of life style. As these factors increase the problem of diminishing space, multiple functional modular furniture concept has become a solution. Reviewing the current scene of the western modular furniture system, it is classified into modular seating system, mopular wall system, modular commode system and modular storage system. Korean wardrobe, which is am mixed style of traditional and contemporary furniture, should change to a closet eventually because of the grand size and unpractical use of space. Since most Korean family, however, have wardrobes already, it will be necessary to have a turning period to systemized the closet space in Korean residential interior. For the turning period, application of the modular wall system would be one answer to substitute the wardrobe.

The overall objective of fitting removable partial dentures at initial placement is to ensure that the patient is given the best possible start with the new prostheses. This may be achieved by checking that: (1) final inspection of the prosthesis, (2) seating of the RPD framework, (3) evaluation of denture base adaptation, (4) assessment of denture base peripheral extensions, (5) occlusal adjustment, (6) remounting the prosthesis, and (7) instructions to the patient.

The superstructure of the railway track undertakes the forces that develop during train passage and distributes them towards its seating. The track panel plays a key role in terms of load distribution, while at the same time it maintains the geometrical distance between the rails. The substructure and ballast undergo residual deformations under high stresses that contribute to the deterioration of the so-called geometry of the track. The track stiffness is the primary contributing factor to the amount of the stresses that develop on the substructure and is directly influenced by the fastening resilience. Four methods from the international literature are used in this paper to calculate the loads and stresses on the track substructure and the results are compared and discussed. A parametric investigation of the stresses that develop on the substructure of different types of railway tracks (i.e. balastless vs ballasted) is performed and the results are presented as a function of the total static track stiffness.

오늘날 자동차는 자동차 자체에 대한 기능적 측면뿐만 아니라 운전자 및 탑승자에게 적절한 거주 공간을 제공하여야 한다는 인간공학적 측면을 동시에 만족시켜야 한다. 특히 부적절한 거주 공간에서 비롯된 좋지 않은 운전 자세는 운전시 신체 각 부위에 과다한 피로를 유발시키고 운전 성능에도 영향 을 미칠 수 있기 때문에 안전 측면에서도 매우 중요하다. 거주 공간의 설계시 출발점이 되는 것은 SgRP(Seating Reference Point)이며 이의 설정은 운전 자세에 직접적인 영향을 미치므로 운전자의 불편도 (Discomfort)를 최소로 하며 운전성능을 높일 수 있도록 설정되어야한다. 본 연구에서는 Driving Simulator 를 이용하여 운전자가 취할 수 있는 Seat의 전후, 상하 위치에 따른 여러 운전 자세에서 운전자가 느끼는 불편도 및 각종 Control의 조작성등의 주관적인 Measure와 운전시의 운전성능을 나타내는 객관적 Measure를 측정, 평가하였다. Seat의 위치는 Whole Body Discomfort, Steering Wheel, Gear, Pedal의 조작성 등의 주관적 종속 변수에는 유의한 영향을 미치는 것으로 나타났으며, 객관적 종속변수에는 유의한 영향이 나타 나지 않았다. 실험 결과를 바탕으로 Regression식을 도출하였으며 이를 바탕으로 Isocomfort Surface를 제시 하였다. 본 연구의 결과는 한국인에 적합한 SgRP 및 Seat Track 설정의 자료로 활용될 수 있을 것으로 기대 된다.

자동차 내장 설계의 주요 검토 사항으로 거주성, 조작성, 시인/시계성, 승강성, 적재성, 안전성 등 을 들 수 있다. 특히, 승용차의 주행 시 운전자는 주위 환경에서 일어나는 상황의 대부분을 눈을 통해 인식하게 되므로, 주행 중 운전자에게 충분한 시계를 확보해 주는 것이 자동차의 설계에서 중요한 요인 이 된다. 본 연구에서는 시계성을 중심으로 미국의 FMVSS(Federal Motor Vehicle Sfety Standard), 유럽의 EEC(European Economy Community), 한국공업규격 등에서 규정하고있는 시계 요소들을 조사 비교하고, 시계 성 평가의 기준으로 활용한다. 시계성을 평가하기 위해 전방가시거리, 전방수평시계, Inside Rear View Mirror와 Outside Rear View Mirror를 통해 볼 수 있는 Viewing angle, Inside Rear View Mirror와 95%ile Eyellipse와 높이 등의 요소를 측정하였다. 측정 결과는 승용차의 운전 공간 내의 0ptimal Eye Point를 결 정하는 데 이용되며, 시인/시계성을 개선하는 Seating Packaging Procedure 개발의 기초 자료로 활용될 수 있을 것이다.

Critics of height argue that it de-humanizes our cities. Yet a critical mass is a necessity for vibrant city life, and height is a key contributor. If we can overcome the environmental impacts and technicalities of building tall and dense, our cities' streets can thrive and prosper. To make this happen, we must move towards working together to share resources, so we can ensure the continuity of the public realm. We already have the tools to do this; the challenge lies in the coordination of the public and private institutions that govern urban space. District heating and cooling systems; shared logistics spaces; care, responsibility and ownership of the public realm between buildings; seamless connectivity between modes of transport; creative combinations of shelter and seating, and the placement of buildings so that they are not overbearing to the streets around them - these attributes can be found in many places, though rarely all at once. This paper looks at the development of the city and offers Barangaroo South, Sydney, which addresses all these aspects, as a potential template for future city planning.

In this paper, the ride comfort of a passenger coach installed with a KT23 type bogie was measured and evaluated through field test in operation routes. The ride comfort level was evaluated and analysed by ISO method and DIC method that were applied generally at railway fields. Particularly three evaluation methods, i.e., a simple method, a full standing method, and a full seating method of UIC513R standard, were fully applied to evaluate the ride quality. Also the vertical and lateral vibration levels on the floor were evaluated by peak-to-peak analysis method.

Recently, in the metro railways, researches on the skip-stop operation and development of the double deck train-set are active, which is to improve the service quality through reducing the passenger travel time and suppling seating service. Constructing new line or reforming the existent line needs huge amount of budget. Therefore, previous to start these large scale projects, scrutiny on benefit improvement, cost reduction and those optimal trade-off is indispensable. In this paper, a quantitative analysis to determine the optimal train service patterns and train-sets necessary is proposed, under the skip-stop operation condition in the metro railways. The analysis models are formulated in mathematical programming model, and tested validity using the LINGO 7.0.

The three design elements of automobile occupant packaging such as pedals, steering wheel, and seat are the most important factors to design an ergonomically sound layout for improving driving comfort and performance. The aim of the study is to find out coherent characteristics of the relationships among three design elements. For this purpose, Triangular Method is suggested. We extracted properties for determining the shape, size, and location of the triangle that is composed of Accelerated Heel Point, Steering Wheel Point, and Hip Point. An experiment was conducted at a seating buck in which the design elements are freely adjustable by the subject to investigate driver's preferred arrangement of three elements. Statistical analyses revealed that there was a subtle change in the shape of triangle according to different percentiles and that the significant difference was observed only for the size of the triangle. The results will be effectively applied to design a comfortable seat packaging layout.
