The precision and reliability of the Computer Image Analysis technique using a desk top computer for extracting information from carcass cross section scans was evaluated by the repeatability (R) and coefficient of variation (CV) for error variance. The 6th and 7th ribs cross section of carcasses from 55 fattened Japanese Black steers were used. The image analysis was conducted using a desk top computer (Macintosh-Apple Vision 1710 Display) connected to a scanner and an image capture camera. Two software applications, Adobe Photoshop and Mac Scope were used interchangeably. The information extracted and measured were individual muscle area, circumference length, long and short axes lengths, muscle direction; distance between any two muscle centers of gravity; cross section total area, lean, fat, and bone. The information was extracted after the processes of scanning, digitization, masking, muscle separation, and binarization. When using the Computer Image Analysis technique by desk top computer, proper digitization and selection of scanning resolution are very important in order to obtain accurate information. The R-values for muscle area, circumference, long and axes lengths, and direction ranged from 0.95 to 0.99, whereas those of the distance between any two muscle centers of gravity ranged from 0.96 to 0.99, respectively. For the cross section total area, lean, fat, and bone it ranged from 0.83 to 0.99. Excellent repeatability measurements were observed for muscle direction and distance between any two muscle centers of gravity. The results indicate that the Computer Image Analysis technique using a desk top computer for extracting information from carcass cross section is reliable and has high precision.

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.

Purpose: The aim of study was to investigate the racial or ethnic differences in FDA-approved medications. Methods: Data on racial-based differences of drugs in PDR (Physician's Desk Reference) were analyzed by searching with keywords, "ETHNIC" and "RACE". Results: There were descriptions related to "ETHNIC" in product directions of 53 cases and "RACE" in 266 cases in 2010 PDR. After excluding 30 cases of duplicates, 289 cases were shown of which 28 cases were verified to demonstrate racial or ethnic differences. Drug category showing the higher racial or ethnic differences was cardiovascular drugs (7), followed by alimentary tract and metabolism drugs (6), nervous system drugs (5), and antineoplastic and immunomodulating agents (3). Pharmacokinetic differences between race and ethnicity were observed most frequently; differences in AUC or Cmax showed in 15 drugs and clearance differences in 7 drugs. Conclusions: This study identified the racial differences in medication usage in PDR. Therefore, the results can contribute to safe use of medication in real clinical settings in regards to the racial or ethnic differences.

This study was conducted to develop a prototype of adjustable desk and chair for students from elementary to high school. The development process started with identifying the problems of existing adjustable desks and chairs that are currently available in the market. The following fundamental design criteria were established and then applied to develop the prototype. The criterion of minimization of production cost yielding lower the market selling price was the most critically considered in view of the school furniture buyers' price-consciousness. Other design criteria used in this development were designing for stable and solid structure, requiring few motions and no tools to adjust, requiring the use of only one hand to adjust, unrestricting the adjustable interval, providing extra space for foot and knee area, reducing weight to move easily, and requiring not to move around for cleaning up floor. To evaluate the performance of the prototype, the adjustability of prototype was specifically compared with both dimensions suggested by KS G 2010(Korean Standards for desks and chairs for students) and current anthropometric dimension in terms of the flexible range of accommodation. Results of this study illustrate that the prototype developed in this study could be accommodated for the both dimensions. As a concluding mark, appropriate adjustable range for various grades and age groups were presented.

The standard of chair and desk is decided to design a science laboratory which would help students giving the chance to show their ability and participating spontaneously. The standard is come by the middle school students physical size of the 1986 national physical standard and they are classified into large, medium and small size. The size of laboratory is determined by the size of desk. the distance between desks and the number of students accommodated. By the middle school students physical standard, the heights of chair are 32, 34, 37cm and the widths of chair are 35, 37, 40cm. The desks heights are 53, 58, 63cm and the size is $110{\times}160cm$. The distance between rear and front of desk is 120cm and the left and right side of desk is 150cm. When 24, 36, 60 students are accommodated in laboratory, the size of laboratories are $9.6{\times}10.5m$, $12.7{\times}10.5m$ and $18.8{\times}10.5m$ respectively.

The purpose of this study is to the improvement of general hospital outpatients waiting time using Theory Of Constraints(TOC) methodology and to the development of a Reception Desk in general hospital. This study is to provide decision-making guidelines for hospital managers and to provide feedback for the efficiency of job process. The target people of the study are outpatients and Cashiers on Chungnam national university hospital in Daejeon. The methods of study are summarized as follows. First, The team managers from a Reception Desk group were appointed. This team managers have the adjustment authority to the Outpatients schedule of doctor and Cashier members. Second, The consolidation of the general Reception desk and special inspection the Reception Desk. A movement line and waiting time of patients were simple and fast to accept. As a result of study, it shows that the TOC is the method for a job process and waiting time improvement, patients' satisfaction increase and we need an objective measurement indexes in the medical treatment industry.
