Purpose：The aim of this study was to evaluate the striatal binding ratio, the anterior/posterior ratio and reproducibility using a template based registration method using the standard MR template as a replacement for each patients MR image. Materials and Methods：This study analyzed the 123I IPT SPECT images of 30 patients with IPD, who were subdivided into 17 patients (56.6$\pm$10.8 yr, M/F : 8/9.) with mild IPD, and 13 patients (56.4$\pm$11.1 yr, M/F : 8/5) with severe IPD. In addition, 11 normal controls (57.8$\pm$14.4 yr, M/F : 4/7) were also analyzed. The ROIs were positioned manually in the same slice showing the highest striatal activity using the traditional manual method, whereas those were positioned automatically in a mid striatal slice of the SPECT image coregistered to the standard T1 weighted MR template. Results : The specific binding ratio (SBR) obtained using the template based registration method strongly correlated with those using the manual method in all groups : normal controls (r=0.85, P<0.001), mild IPD (r=0.84, P<0.001) and severe IPD (r=0.7, P=0.01). The SBRs obtained using both methods were significantly different among the three groups (P=0.05) and the SBRs obtained by the template based registration method were higher than those by the manual method (P=0.05) in all three groups. The APRs obtained by the template based registration correlated with those using manual method in only mild IPD (r=0.72, P=0.0). The APRs obtained by the template based registration method were significantly different from the normal controls and those with mild or severe IPD (P<0.05), whereas those obtained using the manual method were not significantly different among the three groups (P＞0.1). The reproducibility (rmsCV) of the template based registration method was 7.2% (normal controls：5.2%, mild IPD：4.2%, severe IPD：10.8%), whereas the reproducibility of the manual method was 31% (normal controls：19.7%, mild IPD：21.7%, severe IPD：46.2%). Conclusion：These results show that the use of $^{123}$ I-IPT SPECT for assessing IPD is affected by the methods used to position the striatal ROI. The template based registration method using the standard MR template can be useful in diagnosing IPD and assessing the disease severity with a high reproducibility. Therefore, the template based registration method appears to be a good replacement for the manual method.

A bacterium strain, K-73-3, which was isolated from waste soil Korea brewing factory, could grow on acetate as the sole carbone source and accumulated a considerable amount of L-glutamic acid in the liquid culture medium (20 g/l). This strain was named Corynebacterium sp. by the standard method of taxonomy procedures given in the Manual Microbiological Methods.

Bluetooth technology(BT) is a standard for short distance wireless communication and widely used to connect and control various electronic and telecommunication devices without wires, where CSR8670 chip is generally adopted. These BT devices are required to comply with BT specification and the equipments for conformance test are also important. However, the existing BT testing methods have inconvenience in that they are mostly time-consuming procedure due to not only repetitive execution for each evaluation element but also error-prone nature of manual experiments. This paper proposes an automated BT communication test method using CSR8670 chip, which solves the problems related to manual testing methods. The proposed method can reduce the development period of BT products and guarantee the quality improvement owing to the exact system error detection capability.

The military services have sought to improve the overall quality, management, and delivery of military technical information in all of its aspects. The efforts concentrated on developing IETM(Interactive Electronic Technical Manual) by using the application of computer technology for the storage, control, and presentation of maintenance, system-operation, training, and other forms of logistic-support technical information. In this paper, the methodologies are presented to evaluate the operational effectiveness of IETM which consists of confirmity and performance. Confirmity is evaluated by the check-sheet based on the standard of CALS, and performance by the comparison of the technician performance between IETM and paper-TM.

Thoracic kyphosis is occasionally used to describe someone with accentuated thoracic curvature, hyperkyphosis is preferred since kyphosis itself refers to the normal sagittal angle of thoracic curvature. The angle of thoracic kyphosis tends to increase with age resulting in hyperkyphosis in some individuals. The persons who suffer from hyperkyphosis are at increased risk for a variety of adverse health outcomes that include musculoskeletal alteration, physical functional limitations, poor quality of life, falls, and even earlier mortality. Hyperkyphosis may develop from vertebral fractures, degenerative disc disease, either muscle weakness, decreased mobility and sensory deficits. The gold-standard orthopaedic technique for assessment of thoracic kyphosis is standing lateral spine radiographs. Other clinical measures are Debrunner kyphometer, inclinometer, flexicurve ruler, arcometer, flexible electrogoniometer and spinal mouse.

This study was conducted to develop the leveller suitable for power tiller which has been widely used in Korea. Field test was carried out to determine its performance in accordance with the tilt angles of blede, forward velocities , and the length of blade . The results are follows ; 1. Earth moving capacity of the standard leveller was found to be 90~95kg of soil per one swath while working at the 2nd ~4th gears of forward speed. 2. Work performance of model leveller was 2 , 3, 4 times higher than manual operation in distributing additional soil of thickness 6mm , 12 mm and 24 mm on paddyland, respectively. 3. Levelling performance of model leveller on the inclined fields was 7 ~9 times higher than manual operation.

A Technical Manual is the tool that offers a guidance to a maintenance engineer in order to exactly use and maintain of complicated weapon system. Because the modern weapon system are complex and functionality integrated, its quantity is massive. So We spend a lot of money on its publication and suspending recent information. To solve this problem, to reduce a risk of loss and use easily, this study develops the IETM(Interactive Electronic technical manual) which observes the CALS standard. This paper provide the development concept, environment, technic of IETM.

It is not difficult to find risky manual material handling which requires various arm exertion for moving and assembling irregular stuffs in industries. Many of workers have been hurt on their muscular and skeletal system due to the manual material handling. This study is to provide data for isokinetic muscular strength elbow flexors and extensors of Korean male and female adults. Provided standard data for isokinetic muscular strength of elbow flexous and extensors can be used for scientific and systematic analysis of arm exertionl.

Idiopathic scoliosis is a complex three-dimensional deformity of the spine. There is two ways in treatment of scoliosis, normally. In order to prevent a progressive course of the disorder, conservative treatment is started in selected patients. And sometimes, operation is performed to severe patients. But, application standard is vague. So We reviewed the latest medical theses. English language articles in Medline database between 2003 and 2005. 8. 31. were reviewed. The searching words was Idiopathic scoliosis, conservative treatment, brace. exercise. We classified 27 articles. The results of this research demonstrate that conservative treatment is more effective than observation until operation.

Automatic Operation based on ATO (Automatic Train Operation) is necessary for driverless Light Rail Transit business. When this kind of driverless LRT operation plan is made, TPS (Train Performance Simulation) is traditionally simulated at all-out mode and coasting mode based on manual operation. Commercial schedule speed equals to all-out speed minus $9{\sim}15%$ make-up margin. Coasting mode TPS simulation is also run at commercial schedule speed to calculate run time and energy consumption. But TPS based on manual operation should make an improvement on accuracy in case of driverless LRT operation Plan. In this paper, new fast mode TPS simulation using ATO pattern is proposed and show near actual ATO result. The actual ATO pattern can be accurately simulated with the introduction of 4 parameters such as commercial braking rate, jerk, station stop profile and grade converted distance. Normal mode TPS simulation for commercial schedule speed can be designed to have fast mode trip time plus 3 seconds/km margin recommended by korean standard LRT specification.
