This study is going to have been recognized a change of Cervical range of motion with the object 40 persons who sat for many hours before computer. According to the therapy term, sling used joint mobility exercise and Mckenzie was executed by 20 persons Shared. The study results about the effect that Cervical exercise had on joint Range of motion of a VDT syndrome patient were as follows. 1. There was a similar difference a sling used in Cervical Range of motion of joint mobility exercise cure after one-week, two-weet and three-week. 2. The change Cervical Range of motion of Mckenzie exercise has not been after one-week and two-week but a similar difference happens after three-week. 3. There has not been difference between joint mobility exercise and Mckenzie exercise in cure ferm sling used.

Purpose : The study was to evaluate the effect of joint therapy and active exercise on balance and lower foot and ankle muscle MVIC in supination foot. Methods : The subjects of this study were 20. Subjects were 20 to 25($22.20{\pm}1.54$) completed the study and participated three times a week for 4 weeks. Subjects were assessed by utilizing two different EMG MVIC. Results : The change in peroneus longus MVIC significant on pre-test and post test (p<.05). The not change in tibialis anterior, tibialis posterior, peroneus brevis MVIC on pre-test and post-test(p<.05). Conclusion : The study suggest that subtalar joint therapy and active exercise have a increase peroneus longus MVIC for supination foot. Therefore, the subtalar joint therapy and active exercise recommended for supination foot.

Variation of welded-joint hardness and tensile strength of a accelerated-cooled fine-grained ferritic-pearlitic steel with heat input was investigated. In a weld heat-affected zone, a softened zone was formed and it had lower hardness than that of a base metal. While the width of a softened zone increased continuously with an increase of heat input up to 100kJ/cm. the minimum hardness in a softned zone was almost constant after a continuos decrease up to 60KJ/cm. Because of a softened zone, the welded-joint was fractured in the HAZ and its maximum reduction of tensile strength was about 20%. Measured welded-joint tensile strength and calculated minimum tensile strength in a welded-joint was almost same, which means that the plastic restraint of a softened zone did not occur in this experiment. It is believed that as a softened zone width-to-specimen thickness ratio is as high as 2~6 in this experiment, the plastic restraint effect does not occur. Theoretical analysis shows that the plastic restraint effect occurs only when the ratio is below 0.5.

Objectives : The objective of this study is to report the effect of Traditional Korean medical therapy and core exercise on osteoarthritis of knee joint by observing a clinical case study. Methods : Patient with a diagnosis of osteoarthritis of knee joint, was treated by acupuncture, herb medicine, physical theraphy and core exercise. Results : After treatment, Visual Analogue Scale(VAS), Korean version of the Western Ontario and McMaster Universities(KWOMAC), Pain Rating Score(PRS) were reduced from 5 to 2, from 25 to 16, from 55 to 27, and CENTAUR test results were improved. Conclusions : This study showed that Traditional Korean medical therapy and core exercise has meaningful effect on osteoarthritis of knee joint, and more researches should be followed.

This study was conducted to examine the effect of joint mobilization on forward head posture and to propose an effective method to improve correct body posture and balance. A total of eight patients from a Maitland-applied group (n=8) received mobilization therapy to increase the mobility of the cervical joint, with Maitland's movement grade III intensity for 30 seconds of treatment and 30 seconds of rest, for ten intervals, three times a week for four weeks. The craniovertebral angle (CVA) changes before and after the intervention with the Maitland technique were measured as $56.85{\pm}2.31^{\circ}$ before, $63.23{\pm}2.23^{\circ}$ two weeks after, and $64.98{\pm}1.27^{\circ}$ four weeks after joint intervention. There were significant CVA changes before and after the Maitland technique (P <.05). The results of this study suggest that the Maitland technique is useful for improving the head vertebral angle in patients with forward head posture.

There are many sources of errors in the parallel device. This study investigates the effect of a clearance error at a U-joint on the position and orientation errors of the platform of a new parallel device, cubic parallel manipulator. In this study, the limits of errors can be estimated for given conditions.

The Joint Transform Correlator (JTC) has been the most suitable technique for real time optical pattern recognition and target tracking applications. This paper proposes a new application of the JTC system for an analysis of the blurring effect of the optical images caused by a defocused lens. We present the relation between the correlation peak, optical transfer function (OTF), and the amount of blurring caused by focusing error. Moreover, we show a possibility of calibrating the blurred image by simply measuring the correlation peak.

The scale effect of specimens on the shear behavior of joints is studied by performing direct shear tests on six different sizes in Granite. The peak and residual shear stress, shear displacement, shear stiffness, and dilation angle are measured with the different normal stress(0.29~2.65MPa) and roughness parameters. It is also shown that both the joint roughness coefficient(JRC) and the joint compression strength(JCS) reduce with increasing joint length. A series of shear tests show about 56~67% reduction in peak shear stress, and about 18~44% in residual shear stress, respectively as the contact area of joint increases from 12.25 to $361cm^2$. Also the variation of dilation angle is $27^{\circ}$ at normal stress of 0.29 MPa and $6^{\circ}$ at normal stress of 2.65 MPa, respectively. The envelopes considering scale effect for JRC are made for the peak shear strength of rock joint in comparison with the Barton's equation.

Traditional complex joints have used to a wide variety of wooden furniture construction. Dowel joint is the most popular joint s. However design of this joint to meet specified service condition has been hampered by a lack of proven design formulas which can be use to predict their strength. The object of this study is to investigate the withdrawal strength and effect of dowel diameters in wood and wood based materials. The obtained results were as follows; 1. The relationship between withdrawal strength and dowel diameter is found to be linear. 2. Withdrawal strength of medium density fiberboard and Sepetir in end-to-side joints is superior to Antiaris, particleboard and plywood. 3. In end-to-end joints, withdrawal strength of medium density fiberboard is the most superior joint. but Sepetir. Antiaris and plywood have similarly strength and particleboard is inferiority. 4. Withdrawal strength in end-to-end joints of Antiaris and plywood is higher than in end-ta-side joints. But in end-to-end joints of Sepetir. medium density fiberboard and particleboard is similarity in end-to-side joints.
