Objective : This study aimed to identify the characteristics and analyze the quality of studies on memory improvement using a single-subject research design. Methods : Six studies were selected through the Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS), and National Digital Science Library (NDSL). Keywords were memory training, stroke, early dementia, mild cognitive impairment, and single-subject research design. The characteristics and quality levels were analyzed between January 2011 and October 2020. Results : Regarding the quality level, the middle level (7-10 points) was 66.7% of the four articles, and the high level (11-14 points) was 33.3% of the two articles. Reversal designs were used in all studies. Independent variables were errorless learning, smartphone application, cognitive training system (CoTras), spaced retrieval training (SRT) with errorless learning, spaced retrieval training, and iPad applications. The dependent variables included memory, attention, electroencephalogram, instrumental activities of daily living, depression etc., which increased after the intervention. The total session, study period, and intervention time were varied. Conclusion : In single-subject research design related to memory training, occupational therapy intervention was confirmed as an effective method for improving memory and attention. The quality level of single-subject research design was moderate or higher, and high-quality level of studies should be conducted by additional design to increase the validity in the future.

The purpose of this paper is to diagnose the errors by comparing putting motion with the single pendulum pattern applicable to putting in golf skill and order prescription that correct errors of putting. In the modern-day game of golf, putting remains the key to shooting low scores, and the ability to hole putts can turn a good round into a great round A semi-golfer, subject(sex female, age 20yrs, mass 94.3kg, height 1.65m) who has troubles to do putting is chosen. Six cameras, ProReflex MCU240(240Hz) made by Qualisys company is used to capture putting motion and data is processed by QTM(Qualisys Track Manager) and Mathematica 5.0. The result that differentiates the putting and the single pendulum pattern is acquired To make the pattern of subject's putting to the single pendulum pattern quasi-equal, one tries to lower center of mass gradually. As a result of it, one has a similar pattern like the single pendulum Conclusively, to lower C.O.M one orders prescriptions that increase the weight and length of a putter and lower C.O.M subject's segment. Further improvements to the study could be to train a subject according to prescriptions and to monitor putting again. It will probably be necessary to simulate putting motions and to research relations for body shapes and putting patterns in order to establish suitable putting-motions.

Objective : This study examined the characteristics of the literature involving a single-subject research design among positive behavior support intervention studies to improve problem behavior in children with autism spectrum disorders and assess the quality level. Methods : This is a literature study, and the targets of analysis were nine single-subject research papers published between 2011 and 2020. The subject papers were analyzed by dividing them into general characteristics and the qualitative levels according to the content of the research method. Results : Analysis of analyzing the contents of the study showed that the subjects were preschool and elementary school-age children at the same ratio. Furthermore, the study design involved mostly the middle and multiple baseline designs among the behaviors. All papers presented social validity, intervention fidelity, and observer reliability. Problem behaviors included self-injury and aggression behaviors, disturbing behaviors, and seat break-away behaviors, while the most dependent variables were measured through partial interval recording. As a result of confirming the intervention effect, the effect was confirmed in intervention, maintenance, and generalization. All analysis studies showed high-quality levels. Conclusion : This study confirmed the content and qualitative level of the thesis that applied the single-subject research design among positive behavior support intervention studies for problem behaviors of children with autism spectrum disorders. Positive behavior support intervention, an evidence-based intervention for children with autism spectrum disorders, was confirmed an effective intervention for autism spectrum disorders.

An A-B-A-C single subject research design was used to assess the effectiveness of transcutaneous electrical nerve stimulation(TENS) and inhibitive techniques on spasticity in a 10-year-old girl with cerebral palsy. Stimulation electrodes were placed over the sural nerve of the right leg. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. Inhibitive techniques including stretch, antagonist contraction, and weight bearing were used. The tonus of the leg muscle was measured by means of a surface-EMG biofeedback unit. Visual analysis of data indicate that the child showed clinically significant reduction of spasticity in passive ankle movement following 30 minutes of TENS and inhibitive techniques application, respectively. The effect of TENS on spasticity inhibition was similar to that of inhibitive techniques. This result suggests that for this child with cerebral palsy, the application of TENS to the sural nerve may induce short-term post-stimulation inhibitory effects on the spasticity of cerebral palsy. Replication of this study with a more complex single-subject design involving more subjects is recommended to confirm this result.

Objectives : This study was designed to evaluate the effect of moving cupping therapy on the edema of paretic hand in stroke patients. Methods : The subjects were stroke patients with flaccid hemiplegia. Each subject's routine therapy program was maintained throughout single subject ABAB design. During the first week, baseline data were gathered. During the second and fourth week, intervention was provided(total 20minutes of moving cupping therapy, from contralateral to ipsilateral, distal to proximal). During third and fifth week, data were gathered with treatment withdrawn. Edema was measured with hand volumeter and measuring tape. Basically Bayesian analysis was performed using WinBUGS(ver. 1.4), for addition, visual graph and mean score were also presented for comparison between treatment(moving cupping therapy) and non-treatment. Results : The visual graph and mean score showed decrease in edema during the treatment weeks. Overall decrease in edema by moving cupping therapy was verified significantly by using Bayesian ana-lysis(95% credibility intervals). Conclusions : This study suggests that moving cupping therapy could be applicable for reducing post-stroke hand edema. Further research would be needed to establish guidelines for use.

In the United States (US), due to the Common Rule, completely revised in 2017, single Institutional Review Board (IRB) review has become mandatory for government-sponsored multi-institutional research since 2020 regardless of the number of participating institutions. The goal of these changes is to reduce redundant reviews by the IRB at each institution and better protect research participants. In this paper, single IRB and Human Research Protection Program (HRPP) in the US and Korea were compared and considered, and their implications were discussed. A comparison of the HRPP evaluation and certification systems of the US and Korea includes that of SMART IRB in the US and Korea Central IRB, aiming at single IRB review for efficient review with support from the country and building a more efficient national human subject research network in the future. Its comparison and analysis will be helpful in deriving future tasks and development directions of single IRB and HRPP in Korea.
