국내에서 고층건물의 제연시스템으로 급기가압 제연시스템이 일반적으로 사용되고 있는데, 기존의 급기가압 제연시스템의 설계방안과 같이 한개의 급기풍도를 통해 누설량과 보충량이 동시에 공급될 경우에는 부속실과 옥내간에 형성되는 차압이 설계기준에 미달하거나 과압이 될 가능성이 매우 높아져서 급기가압 제연시스템의 설치목적을 달성하지 못할 수 있다. 이에 대한 개선방안으로 본 연구에서는 누설량의 공급과 보충량의 공급을 각기 다른 유로를 통해 수행하는 방안 및 장치구성을 제시함으로서 고층건물에서 화재 발생시 안전한 피난환경을 제공하고자 한다.

The purpose of current study is about how to construct wall-type APT in slip form and Deck plate applied different connection of materials that wall and slab. A proposal construct's solution is using the continuous a binding string that the main of contents are slab or stairs which horizon structure part construction is joined the vertical structure part, new we Proposed of 2 solution that new technology development. We'll suggest that the development is in the construct of higher stories APT more better other construction method. We expect that the new method is good but we have many things to solute themes. Thus, we decided that this development contents are needed that correct structural investigation and constructor's security of speciality and through a fact construct, correct verification.

A concept of preliminary design for mid-size superyachts is explored. First, the profile of a superyacht is interactively designed with the help of freeform curve functionality and graphical user interface (GUI) based interaction. The hull form is then constructed using major characteristic curves such as design waterline, deck sideline, and sections in addition to the predefined profile curve. After exterior hull modeling is done, the arrangement of significant interior spaces of all decks is carried out. A genetic algorithm is exploited to find a space arrangement by considering space fitness values, space proximity, and stairs connectivity of relevant spaces. A goal of the paper is to offer a step-by-step procedure for superyacht design from scratch or when initial information is not sufficient for complete design. For this purpose, a GUI based superyacht design system is developed. This design approach is expected to help users interactively design mid-size superyachts.

This study attempts to examine and to analyze the characteristics of transparent materials and its methods to apply in space. the ability to see through a physical element, whether it is clear glass, sandblasted acrylic, or a delicate fabric, can have a dramatic and sensory effect on the overall perception of a space. The various range of Transparent materials and product in glass, plastic, fabric, and grid now gives us the potential to maximize the flow of light in our enclosed space. This research will explore how transparent, translucent, and semi-opaque elements can be used within the interior with full range of see-through materials. The transparent materials can be divided in two level - as structural elements and as stylish accessories. A glass partition or floor, metal mesh stairs can create divisions or link one space to another while maintaining effective levels of natural light. there is also various level of products from glass chair to basin. With the enthusiasm for using transparent materials, transparent materials will be more decorative and powerful application while still maximize the highest possible flow of light.

An effective design of a public space that properly functions as a resting place in city can be found through the community facility studies. This study, based on the ecological psychology, discusses the mutual relationships between human behaviors and physical and social environment. It is demonstrated that design elements, such as chairs, tables, stairs, a flower bed, a stair-shaped exterior wall, a pond and others play important roles in providing environment for different human behaviors in public space. These environmental design elements also increase a variety of behavior for users.

The purpose of this study is to suggest the basic data which can be used as comfortable dwelling circumstance to keep a life as self-reliant and secure as possible for their activity daily life in the elderly housing. In the results of this study we can be found that the elderly complain many difficult when they do their activity daily life in the interior housing space. See the aspect of space, improvement of architectural arrangements like stairs, lighting arrangements, bathroom, kitchen are required and in the characteristic of elderly, we can found the effect of health condition, education in activity daily life.

In recent, there are a lot of problems such as shortage of construction workers, complicate progress of work and so on under RC construction. To solve these problems, the construction methods without form-work are used in the main structural members - beam, slab and stairs. However, there isn't yet form-workless system for columns. The purpose of this study was to experimentally evaluate the structural behavior of full scaled no-form system columns reinforced with steel sheet forms and angles. The main variables are 1) comparison of concrete member strength with and without reinforcement, 2) effect of L-angle.

The mobile robot is used as an instrument of transportation in automated plant. But the greater part of the moving method is the wheel-type. The wheel-type robot is easier control than the track-type, However the track-type is better than the wheel-type in bad landform(bend landform, an incline plane, stairs). In this paper, we propose the navigation algorithm of track-type robot in order to improve a defect of wheel-type. We experiment in bend landfrom and even ground to differentiate the navigation method. To estimate robot pose, we use the 80196 in a close distance and the vision-board in a long distance. Each data is managed in main PC and then the part of managing correspond to every sensor. We also use twelve supersonic wave-sensors to recognize external surroundings. As the result of experiment, we analyze the algorithm of control and make possible surroundings-adaptation.

This study is to research on the condition of safe environment of kindergartens. This study is to supplement the preceding study which was based only on survey to show the result and analyze the condition and problems of the safety of kindergartens to suggest the basic database of indoor environment that cause accident. First as a theoretical study, we analyze the preceding studies according to the related regulations. And we made checklist based on this and visited and investigated two kindergartens where applied for the case study As the result, we could understand factors that can cause accidents from classroom, corridor, door, stairs, balustrade, toilet, kitchen, front door, and fire exit/shelter. Especially, in case of fire exit/shelter, the whole renewal of kindergarten was necessary which is difficult. But, though it can not be advanced right away, they should try to have facility expansion and repair works gradually. And for more study on this, active cooperation from kindergartens are in need.

The purpose of this research was to ascertain the optimum rear slit length of tight skirts in terms of comfort and appearance. The typical measurements of tight skirts on current market were recorded and a questionnaire survey of women in their twenties was conducted in order to find out the current conditions of the skirts and specific complaints about motion restrictions. Just over half the respondents (50.4%) reported that they had experienced damage to the slit usually when they were stepping on a bus and also walking and running. The clothing test showed that the slit length increased as the motion went from "walking" to "going up stairs", and to "stepping on a bus" In addition the slit length significantly decreased as the hem circumference of skirt became wider. On the basis of those results, a wearing test, evaluating sensual comfort and appearance, was also conducted and the results showed that the slit length of 385mm was most prefered.
