The interpolator is usually built in hardware (logic circuitry), and the interpolator fabricated in a single LSI chip is recently made use of in most NC controllers, making the system more compact. However, the LSI interpolator not only has the technical difficulties but also requires high cost, in its fabrication. To solve these problems, we tried to find the method of interpolation by software, and succeeded in developing a program which, executed by INTEL's 8085 microprocessor, can distribute the input pulses of up to 4.0 [Kpps] for the linear interpolation and 3.0 [Kpps] for the circular interpolation. This paper presents the algorithm used to reduce the execution time and the flow chart of the interpolation program, and also shows the possibility of software interpolation. The interpolation program designed in assembly language is presented in the appendix.

Objective : The purpose of this study was to investigate the effects of paired-group sensory integration therapy on sensory processing, peer interaction, and play development of four-year-old children. Methods : This study involved 13 weekly sessions of a four-minute intervention as well as an initial 10 minutes of parental counseling for those without experience of paired-group sensory integration therapy. The intervention consisted of sensory processing activities and various occupational activities, and the children's Short Sensory Profile (SSP), Penn Interactive Peer Play Scale (PIPPS), and Knox Preschool Play Scale-Revised (KPPS-R) were measured before and after the sessions for comparison. The results are presented using visualized data. Results : After the paired-group interventions, all subjects showed improved sensory processing ability according to their SSP scores and improved play development on the KPPS-R. Moreover, the frequency of negative interactions decreased in the PIPPS measure. Conclusion : This paired-group sensory integration therapy had a positive effect on sensory processing, peer interaction, and play for children with developmental delay. In the future, research that applies this kind of paired-group intervention in various age groups would be useful.

Speed, accuracy and smoothness are the important properties of pan-tilt camera. In the case of a high ratio zoom lens system, low vibration characteristic is a crucial point in driving pan-tilt mechanism. In this paper, a novel micro-stepping controller with a function of reducing vibration was designed using field programmable gate arrays (FPGA) technology for high zoom ratio pan-tilt camera. The proposed variable reference current (VRC) control scheme reduces vibration decently and optimizing coil current in order to prevent the step motor from occurring missing steps. By employing VRC control scheme, the vibration in low speed could be significantly minimized. The proposed controller can also make very high speed of 378kpps micro-step driving, and increase maximum acceleration in motion profiles.

Objectives: To investigate efficacy of Korean medicine for patients with Parkinson's Disease (PD) with pain. Methods: We performed a retrospective review of the medical records for patients diagnosed with PD between 2012 and 2019 at Gangdong Kyung Hee University Korean Medicine Hospital in South Korea. Results: Twenty-two patients with King's Parkinson's Disease Pain Scale(KPPS) scores at least twice were analyzed for evaluating the efficacy of Korean medicine for pain treatment in PD. The mean total scores before and after Korean medicine treatment were 15.23±1 .01 and 9.2±8.7, respectively, and the mean difference between the before/after total scores was 6.0±5.8 (P<0.001). Specifically, the score of radicular pain was significantly decreased (P=0.048). Conclusions: These findings suggest that Korean medicine could be beneficial for reducing pain associated with PD. Clinical efficacy should be confirmed by further studies, such as large-sample cohort studies and randomized controlled trials to clarify the pathological pain relief mechanism and the analgesic effect of Korean medicine.

The purpose of this study was to investigate the effects of sling and vibrator application of knee push-up plus motion on trunk muscle activities. Ten healthy adult males(age, 23.00±0.45 years; height, 176.60±1.64 cm; body mass, 67.50±1.22 kg; and BMI, 21.65±0.34 kg/㎡) were participated in this study as subjects. Three types' knee push-up plus motions were performed(basic knee push-up plus motion, BKPP; knee push-up plus motion with sling, KPPS; knee push-up plus motion with vibration, KPPV). We measured the right side's trunk muscle activities of the upper trapezius(UT), pectoralis major(PM), serratus anterior(SA), rectus abdominis(RA), and external oblique(EO). The research findings were as follows. UT, PM, SA, RA, and EO muscle activities were greatest during KPPV(p<.001). These results are expected to serve as reference materials for knee push-up plus motion applications in training programs for trunk muscle strengthening.

Objective : Purpose of this study is to discuss benefits and implications of the clinical reasoning process and re-evaluation in the OTIPM by introducing a single case that occupational therapy intervention is provided based on the OTIPM. Methods : The case subject is a boy aged 5 years and 10 month who had diagnosed as attachment disorder and anxiety disorder from a pediatric psychiatrist before. The boy is referred to sensory integration therapy clinic and underwent occupational therapy intervention service twice a week for four month. Therapeutic activities for the intervention were consisted of sensory integration activities for restorative model, care-giver education for educational model, and performance skill training for acquisitional model. Measurements used in the initial evaluation are JSI-R, DDST-2, Social Maturity Test, KPPS-R, and observation-based performance task analysis. For the performance task analysis, performance skill items were constructed based on the Occupational Therapy Process Framework (OTPF), and those were assessed by the evaluation system of Assessment of Motor and Process Skill (AMPS) and Evaluation of Social Participation (ESI). Results : The detail process of implementing of the OTIPM in this study is reported by following four phases; 1) establish client-centered performance context; 2) establish baseline and interpret cause (initial evaluation); 3) intervention planning and implementing; and 4) recognize intervention outcome (reevaluation). Conclusion : In this case, occupational therapist could provide the client an occupation-based intervention within comprehensive performance context based on the OTIPM. Therapist could clearly identify the cause of problematic performance skills and behaviors and so provide effective intervention to improve client's occupational performance. Additionally, it was found that client's satisfaction of the intervention can be raised when the concept of 'who is the client' is expanded based on the OTIPM. From this study, it is proposed that OTIPM may be a model educible 'comprehensive' enhancement of 'specific' occupational engagement, as it considers both improvement of occupational performance and satisfaction.
