  • Structure is one of the most important components in designing chairs, since a chair should support the weight of users and make them feel comfortable. However, previous studies have focused on examining the materials and the techniques of processing of chairs, but less on studying the structures to facilitate human friendly use enough to influence the change of the current chair design. The purpose of this study is to analyze the composition element in structure of the chair design specifically from 2000 to 2008 the fundamentals to achieve quality chair design. This study examined 386 chairs which the most reputable furniture fair, the Milan International Furniture Fair exhibited from 2000 to 2008. 386 chairs were chosen from 72 companies which passed the popularity and ranks. 24 Components of the structure of chairs were used to annalize the 386 chairs. The structural types of chair design included 51 kinds. Among them, the most representative types appeared to be 5 kinds. Particularly, the single structure chair was comprised of 25%, its productivity has increased steadily since 2004 which indicated that the structure of chair has become simplified. According to the components of chair, classified structure types were analyzed into (1) a single structure consisting of one component, (2) a simple structure with two components, (3) a complex structure with three components, and (4) a multiple structure with four components. The majority of chair types followed the order of the single structure, simple structure, complex structure, and multiple structure. The results of the analysis on the structure of chairs indicated that the structure of chairs has been changed toward single type No. 24 and simple type No. 6+13.

  • School children sit long on chairs in their classrom. Their posture is closely related to their chairs. Study of this relationship is very imporant for the health and education of school children. This report presents the results of study condcuted to determine the present status of classroom chairs and solve any problems identifede. The study involved 125 teachers in Seoul and Pusan, 175 fourth graders in Seoul, and 109 fourth graders in Puasn. The body dimensions of the school children and the dimensions of their chairs and desks were measured, and their postures while they studied at their desk were photographed. The following problems were identified as a result of the investigation: (1) Chairs are allocated to pupils according to their stature. (2) The teachers are not satisfied with the chairs and the method by which the chairs are allocated to their pupils. (3) The pupils complain of low seat height, narrow seat, and hard backrest, among other conditions. (4) The pupils select a chair one size larger than that suggested by their body size. (5) The poor posture of the pupils is traced to the seat height and sasyaku$(sitting height {\times} 1/3-1)$ of their chairs, their habit, their way of holding pencils, and lack of instruction by their teachers. The following recommendations are made to solve these problems: (1) Adjust the seat height and desk height to accommodate the pupils. (2) Provide both teachers and pupils with adequate knowledge of chails. (3) Provided each pupil with one desk and make the desk adjustable to sit his or her body dimensions. (4) Allocate a chair and desk to each pupil for his or her exclusive use. (5) Reserch and develop conversion tables that help to find suitable chails for individual pupils. New values of sasyaku and desk height, not specified in Korean Industrial Standards(KS), are proposed.

  • This paper examines the combinations of factors influencing the absorption characteristics of theatre chairs. One-tenth scale model chairs and listeners that closely approximated the absorption characteristics of full scale theatre chairs were used to measure the interactive effects of the test variables on the chairs absorption characteristics. The test variables were the type of chairs, the row spacing, as well as the presence of people and carpet. The variations of absorption increments with varied row spacing tended to be smallest when the chairs were less absorptive, i.e. with less carpet or occupants. The incremental effects of adding occupants or carpet averaged over three row spacings varied over frequency.

  • This study is focused on the chairs for students, especially, middle school students who grow rapidly compared with other group. We make a certain definite possibilities by the scientific and medical comparison of the approved chair with existing chair about the function of feet-height control & the application of the flexible back. The object of this test is middle & high school student (ratio of gender is the same) in Inchon. And the study types are two. One is to bring a matter and to suggest a design as alternative, the other is to verify propriety of the alternative. The major finding from the research are summarized as follows: 1) K·S standards for existing chairs are not proper to the growth rate of present juveniles, and they don't cope with proactive the discrepancy of growth pace. 2) Existing chairs have caused troubles by using only the fixed back of a chair. This troubles made bad influences on juveniles in a growth period. 3) Even existing chairs can adjust the back of a chair, they can be easily broken , and if they adjusted once, they can't be easily controled. Furthermore, it is Impossible to manage them because of the rust of control parts. 4) In the case of supplying the same sizes of them, juveniles who are different to growth rate respectively, can't accept the chairs. Even supplied adjustable chairs, they cant be ideal types of chairs in Open Classroom mode.

  • Uniform and integrated college desks and chairs have low efficiency of loading for transportation and delivery and low efficiency of storage for warehousing due to their simple uniform physical properties, thus increasing logistics costs for companies and decreasing their competitiveness. In an effort to overcome the limitations of previous studies, this study analyzed the stages of logistics for desks and chairs in college lecture rooms via the transportation route including the factory warehouses and local warehouses and via the delivery route from local warehouses by the region to the orderers including college lecture rooms. The study developed a model for the rationalization of corporate logistics by making a variable folding desk and chair capable of distance adjustment according to height to replace the uniform and integrated college desks and chairs in lecture rooms. A model was developed between the old uniform and integrated college desks and chairs and the new variable folding desks and chairs for three scenarios of cost development including product storage costs, transportation costs from the specialized factory warehouses to the local warehouses by the region, and delivery costs from the local warehouses to college lecture rooms as the orderer. For the generalization of the model, it was applied to each of the 90%, 95%, and 99% service levels.
