The objective of this study is to evaluate the interior elements supporting the safety, mobility and accessibility for the visually impaired persons in the public, government, and other facilities. Ten facilities were analyzed with a checklist based on the architectural codes and the users needs. Also theses facilities were reviewed with mandatory items of the Ministry of Health and Welfare. It appeared that the arrangement of elements such as stair, elevator and restroom, the plan of circulation path and the signage of way-finding had more problems than the details of each element. In addition, institutional facilities for the blinds and trainstation provided easy accessibility, adaptability and mobility compared to the hospital and bus terminal. Suggestions were provided to solve the problem which were found.

In this paper, the cost-effective design of output reactor which is used to suppress the over-voltage at the motor terminal in the Adjustable Speed Drives(ASD) application is proposed. In the elevator drive system, the power cable length is relatively shorter than other ASD applications and then the over-voltage at the motor terminal depends on the frequency characteristics of the output reactor at the over-voltage operating frequency. The over-voltage suppression mechanism of output reactor in ASD application is analyzed and the dominant parameters of output reactor for the over-voltage suppression are extracted. Using these parameters as the design values and considering the high frequency characteristics of iron core in the reactor, a new cost-effective structure of output reactor is proposed. Experimental results of the conventional reactor and the proposed reactor with a 15kW induction motor are given to verify the proposed scheme.

The objective of this study is to propose the basic design plan of system by comparing and analyzing application environment of lift and elevator group control system, as preliminary study for the application of group control system to lifts for high-rise construction. The basic design plan is suggested in terms of group control algorithm, hall call system type, operation information recording device, information communication method, and operation method. The results of this study can be used as basic data for software and hardware design for application of group control technology of lifts for super tall building construction and ultimately contribute to improve the operation efficiency of lift for high-rise construction.

RTB (Real-Time Bidding; 실시간 경매 방식)시장이 기하급수적으로 빠른 성장을 보이고 있는 상태에서, 내년 미국 RTB 시장은 200억 달러를 뛰어넘을 것으로 예상되는 가운데, 이러한 상황은 빌딩 내에서 엘리베이터를 기다리는 사람들에게 광고를 노출할 수 있는 새로운 서비스가 될 것이라 생각한다. 대부분의 사람들은 30초에서 길게는 1분이상의 엘리베이터를 기다리면서 스마트폰을 만지며 시간을 보내고 있다. 본 연구팀은 RTB시장에 엘리베이터 탑승객을 연계할 수 있는 스마트 폰 기반 광고 서비스 및 회사 전반적인 업무에 도움 되는 서비스를 제안하고자 한다.[1] 본 연구팀이 진행한 연구는 엘리베이터 사용자의 위치를 바탕으로 개인의 정보를 활용해 그에 맞거나 상응하는 정보를 찾아내 제공하는 서비스에 관한 것이다. 이는 향후 RTB와 연계하여 개인에게 맞춤 광고할 수 기능등의 새로운 수익 창출이 가능할 것으로 예상한다.

Purpose: This paper aimis to analyze the characteristics of ward plan of Korean hospital architecture constructed in each periods and identify the change since 1945. Methods: Literature review was conducted while ward plans for analysis were sellected. And then the important points of ward design were analyzed in each periods. Results: The important points of ward design - type of corridor in ward plan, number of beds per nursing unit, location of nurse station, organization of multi-bed rooms, location of patient toilet, number of day room, concentration and separation of elevator halls for patient and general- were analyzed and the characteristics of change were identified in each periods. Implications: This paper could be a basic data for arranging the history of hospital architecture in Korea.

As the seniors and the disabled has increased, the demand for cultural centers has also increased in many local areas. This means that the local cultural centers designed from the viewpoint of universal design are needed, so that to be used by everyone without any difficulties. This study examined the applicability of universal design principles to the public service areas of the local cultural centers. The subject cultural centers were three local ones which had seating capacity of more than 1,000 and opened after the year of 2,000 in Gyungnam. The spatial scopes of the study were six public service areas of the local cultural centers : entrance area, corridor and pathway, stair, ramp, elevator, and rest room. The total 65 items for evaluating the applicability of universal design were selected and examined for six areas. On the whole, accessibility, such as wide pathway and flat floor was good. However, the following improvements were needed. 1) Handrails and rounded corner were needed on walls. 2) Consideration of the visually impaired like as braille sign was needed. 3) The handrails on ramp should be installed for usability. 4) The automatic door would be more useful to the physically disabled users. 5) Wider space and familiar handrail design and color were needed in the rest rooms for the handicapped.

IFC based open BIM has internationally developed as a solution for interoperability problem among different software applications. Despite much interest and effort, the open BIM technologies are rarely introduced to the construction industry and need more technical development for a practical application as well. This research aims to develop automated code checking modules for quality assurance process of BIM data. The research have analyzed domestic regulations focusing on super-tall buildings and developed open BIM-based code checking modules for the evacuation regulations. The modules are able to validate evacuation regulations such as installation of emergency elevator and fire safety zone. The authors expect to improve the process of BIM quality assurance and enhance the quality of BIM data by this research on automated checking system.

In the modern market economy, where the consumers are increasingly seeking pleasure rather than convenience, a variety of retailers are making every effort to promote sales records. In order to achieve this goal, the division of work needs to be effectively performed and the allied enterprises need to cooperate with each other. Consequently, the Customer Relationship Management(CRM) system should be established through the research and analysis on brands and consumers. It is also necessary that the enterprises should cooperate mutually, using the PRM system which makes it possible to share the information from the CRM system. This report is going to propose a desirable cooperation which is reguaired in Retail Shop Design. And it will be done by describing the relation between CRM & PRM and the marketing based on brands and consumers.ere it examines closely the vibrating unit of the elevator and propose the countermeasure of it.

Before incorporating the earthquake-resistance design in design code(998), most of existing residential buildings were built without having lateral resistance capacity in addition to their structural peculiarity such as exterior stair ways, exterior elevator room. For these reasons, the retrofitting research demands for existing buildings arise recently and many retrofitting methods are proposed. These tasks are important to reduce the enormous economic loss and environmental issues. In this study, Scaled residential buildings with/without lateral resistance were tested and monitored with external lateral load especially toward the longer side of the building. From these experiments, enhanced retrofitting methods of old shear wall system are proposed and also compared with structural analysis.

During the past decades automated storage/retrieval (AS/R) systems have been dominantly implemented in most industrial fields due to their handling efficiency and high utilization of storage space. Such AS/R systems consist of several modules each of which contains two racks and a S/R machine. This paper proposes a design of the hybrid AS/R module which can be adopted without too much initial expenditure by most of small-and-medium sized companies. The hybrid module consists of an AS/R module on the upper floor and a traditional warehouse module on the lower floor. For the AS/R module, analytical expressions of the expected travel times for the S/R machine and the elevator per operation are derived. The expected travel times represent the performance of the module and thus can be used for its economic design.
