Objective : The purpose of this study was to identify the effect of crafts and handwriting on bilateral coordination during task performance. Methods : Randomly selected 30 college students without hand disability were invited for the study, and grouped 3(test group 1 for crafts, test group 2 for handwriting, and control group) with 10 students per group respectively. Then Jebsen-taylor hand function test, Purdue pegboard test, and Minnesota manual dexterity test were employed for evaluating changes before and after the intervention. Results : After training intervention of crafts and handwriting for two test groups, test groups showed better bilateral coordination significantly than the control group. Especially test group 1(crafts) showed a bigger difference at Jebsen-taylor hand function test, and likely test group 2(handwriting) did at Purdue pegboard test. Conclusion : It was found that crafts increase bilateral coordination, while handwriting increase hand dexterity during task performance. That is, crafts and handwriting affect tasks differently. Further studies applying various crafts and handwriting for many age groups will be helpful for identifying the better way of occupational intervention for individuals in lack of bilateral coordination.

In this paper we present the Bimodal-tram simulator using the PXI embedded real-time controllers. The Bimodal-tram is developed in KRRI (Korea Railroad Research Institute). The vehicle can be automatically operated by navigation control system (NCS). For the automatic driving, the vehicle lanes will be marked with permanent magnets that are placed in the ground. The vehicle is controlled by NCS. NCS governs the manual mode and automatic mode driving. The simulator is designed by an identical conception with the real control condition. The dynamic motion of vehicle is simulated by the nonlinear dynamic model. The control computer calculates the control values. The signal interface is linked by CAN communication. The simulation is processed by real-time base. The test driver can see the graphic motion of vehicle and can operate the steering wheel, gas and brake pedal to control direction and velocity of vehicle during the simulation. At present, the simulator is only operated by manual mode. The automatic mode will be linked after the control algorithm is finished. We will use the simulator to develop the control algorithm in the automatic mode. This paper shows the simulator designed for Bimodal-tram using real-time based controller. The results of the test using the simulator are presented and discussed.

Objectives : Scalenus anticus syndrome and Piriformis syndrome is representative of myogenic Nerve entrapment syndrome, and their clinical symptoms are similar to HIVD(herniated Intervertebral disc) of cervical or lumbar spine. But, distinguished by muscle test, these syndrome apply to Meridian-muscle therapy. Methods : Meridian-muscle therapy consists of Ashi(阿是)-point therapy, taping therapy, myofascial release technique, manipulation, their based on the traditional meridian-muscle theory. This theory is similar to myofascial pain syndrome in western medicine. The study population consisted of 9 patients who were already diagnosed as Nerve entrapment syndrome with radiological examination & physical examination and muscle test. The evaluation of clinical outcome was done by Visual Analogue Scale (VAS) and Pain Assesment Questionnaire(PAQ). Results and Conclusions : After treatment, All patient's VAS is decreased as $2.11{\pm}1.59$ and the evaluation of clinical effect was excellent(6 cases) or good(3 cases) according to PAQ. Conclusively, Meridian muscle therapy is efficacious against Nerve entrapment syndrome.

Rockfall protection fence which is used for mitigation of rockfall hazard, has been constructed without consideration of lithology, height and dip angle of rock slope. However, those factors should be considered for the construction of the protection fence. In addition, the protection fence should be evaluated its performance by in-situ test in order to utilize the fence effectively. This is the first full sized rockfall test in Korea. For this test, the rock cut slope whose height is about 20 m and dip angle is 65 $^{\circ}$ has been chosen. Based on the preliminary simulation procedure, four different concrete balls (0.5 ton, 1.0 ton, 2.0 ton and 5.0 ton) were prepared and four different types of protection fence were constructed. The results of this test will be utilized in the establishment of rockfall protection fence construction manual.

To evaluate whether or not their product is in conformity with its drawing, today's factories manufacturing rubber and/or plastic products use manual process. In manual conformity inspection process, a person decides conformity as comparing drawing to image of product with his eyes. The manual process is tedious and time-consuming in addition that it is impossible to automatically record various informations related to inspection. To solve such problems, this paper proposes automatic drawing conformity inspection system based on computer vision technologies such as image feature matching and bilinear interpolation. The test results show that proposed system is a lot faster when comparing with manual system.

Recently automatic equipment has been well popularized for the erythrocyte sedimentation rate, a widely used test, but no standard quality control has been established yet. Thus, we are going to report a case that established and applied a quality control method using the TEST 1 automatic analyzer. For internal quality control, we adopted the repeatability test through comparison with daily mean check, with a manual method using patients' specimens and with the results of a test on the previous day. In order to set the tolerance standard for each quality control method, we compared the results of 50 specimens that showed a wide range of ESR results and examined correlation and differences according to result. After setting the tolerance standard, we applied the standard at tertiary university hospitals for 120 days and investigated positive rates and re-examination rates. If the tolerance standard was exceeded, the cause was also identified. We selected a specimen of below 25 mm/hr (T1), one between 26-50 mm/hr (T2) and one of over 51 mm/hr (T3) at random. The correlation between the manual method and the automatic method was quite high (r=0.98), and it is found appropriate to set based on differences in result values below 25 mm/hr, the upper limit of the reference value, and based on differences in the percentage of result values above 25 mm/hr. Accordingly, we set the criteria for rejection above 10 mm/hr and above 20%. When the criteria were applied in the laboratory, 1.7% of specimens in the range of T1, 8.3% of those in the range of T2 and 7.5% of those in the range of T3 were rejected. Because all the rejected ones fell within the tolerance limit in re-examination calibration verification was not carried out. With the wide popularization of erythrocyte sedimentation rate analyzers that can carry out a lot of tests quickly using automatic methods, it is necessary to improve the reliability of test results by establishing internal quality control policies. We expect that an agreed standard quality control method may be established based on the method proposed in this study.

For a large corpus of time-aligned data, HMM based approaches are most widely used for automatic segmentation, providing a consistent and accurate phone labeling scheme. There are two methods for training in HMM. Flat starting method has a property that human interference is minimized but it has low accuracy. Bootstrap method has a high accuracy, but it has a defect that manual segmentation is required In this paper, a new algorithm is proposed to minimize manual work and to improve the performance of automatic segmentation. At first phase, voiced, unvoiced and silence classification is performed for each speech data frame. At second phase, the phoneme sequence is aligned dynamically to the voiced/unvoiced/silence sequence according to the acoustic phonetic rules. Finally, using these segmented speech data as a bootstrap, phoneme model parameters based on HMM are trained. For the performance test, hand labeled ETRI speech DB was used. The experiment results showed that our algorithm achieved 10% improvement of segmentation accuracy within 20 ms tolerable error range. Especially for the unvoiced consonants, it showed 30% improvement.
