  • The characteristic of “Korea LRT Carbody” is designed by using AED(All Extrusion Design) method. This is developed in Europe and be introduced in this paper minutely. The window type of “Korea LTR” has no supported frame, so the passengers ensure the outside view widely. The passenger's door will designed by plug type - This is the first time in Korea. In this report we have an object to the strength analysis for the carbody design. For the purpose of safety and lightening, we are going to research the section of thickness through optimization design.

  • PSD(platform screen door) was completely installed at all of Seoul subway station(line 1~8) using 640million people per day by 2010. After installation of PSD, the influence of train induced wind at platform decreased, but is estimated to increase in subway tunnel. In this paper, train induced wind occurred by pass of subway at platform was measured and analyzed using numerical analysis by computational fluid dynamics.

  • This paper describes a method of aisle following of a mobile robot using machine vision. As a navigation guide, Black strip painted on the lower part of wall of aisle is used. The offset of the vehicle position from the center of aisle and the heading angle are determined from the binary image of guide strip captured by a CCD camera. To remove the effect of noise. i.e. break of guide strip for the door or reflection of light, pixel sampling method together with consistency check of the incline for the sampled pixels is used.

  • In this paper, a disassemblability evaluation has been investigated quantitatively by using an ease-of-disassembly design method. Four categories such as recognizability, approachability, separability, and treatability have been analyzed in details. A simulation software for estimating the ease-of-disassembly design method has been developed and applied to door trim and spin basket respectively as an example.

  • A demonstration facility for advanced spent fuel conditioning process (ACP) is under construction in KAERI. In this hot cell facility, all process equipments and materials are taken in and out only through the rear door. The working table in front of the process rear door is specially designed to be openable for the efficient use of the space. This paper presents the structural safety analysis of the openable working table, for the normal operational load condition and accidential drop condition of heavy object. Both cases are investigated through static and dynamic finite element analyses. The analysis results show that structural safety of the working table is sufficiently assured and the working table is not collapsed even when an object of 500 kg is dropped from the height of 50 cm.

  • Purpose: The purpose of this study is to identify the difference in toilet approach way by wheelchair users according to the direction of the door and to suggest the layout of the toilet rooms most accessible to the wheelchair users. Methods: Survey to wheelchair users about approach to toilet have been conducted for the data collection. 90 answers have been analyzed statistically by SPSS 19.0 program. Results: The conclusions of this study are as follows. Firstly, spinal cord disorders prefer diagonal approach and lateral approach to the toilet, but brain lesions prefer diagonal approach and frontal approach to toilet. Secondly, the manual wheelchair users prefer the diagonal approach and the lateral approach to the toilet, and the electric wheelchair users has a different approach way to the toillet depending on the direction of the door. Finally, the layout of accessible toilets have to be designed for the diagonal approach to toilet, which is most preferred by wheelchair users. Implications: The toilet approach varies according to the disability types and the wheelchair types. Therefore, the size of accessible toilets should be larger than now considering the access of variety wheelchair users.

  • This study was designed to investigate the relationships between children's physical growth and health and their raising conditions and to find out the important conditions to improve their physical growth and health. The rasing conditions were classified into three major parts; i. e., family conditions, conditions of nutrition up-taking, and conditions of rest or sleep and exercise or play. Then, the questionnaire including the items to survey these three areas of raising condition and the items to evaluate the health status were given to children' mothers or fathers and filled up by them. The data of their 4 anthropometric measures; body weight, stature, sitting height and chest girth, were also collected from their latest records of health examination. The data of health status were converted to health scores representing 6 domains of health; digestive organs, respiratory organs, auto-nerve systems, fatigue, others and health as a whole. Then, correlations of raising conditions were determined with four antropometric measures and 6 health scores as criterion variables. Then, number of families to live together, and child's birth order in the domain of family conditions, habits of unbalanced diet, eating frequency of eggs, fruits, green and yellow vegetables, light colored vegetables, milk products in the domain of nutrition up-take, and the time for study at home, the place for play, the number of friends to play with together, the hours for playing out of door, the hours for playing sports, and the hours to move their body for assisting house keeping were picked out to investigate their relationships with physical growth and health status. Then, their habits of unbalanced diet and eating frequency of eggs, green or yellow colored vegetables, and milk products were found more influential conditions and more over, birth order, the time for study at home, the time to play out of door showed moderate degree of connection with physical growth and health status in early childhood.
