This study was analyzed by applying AMSTAR-2, a methodological quality evaluation tool, to evaluate the quality of domestic meta-analysis papers on rehabilitation interventions for stroke patients. The purpose of this study is to provide guidelines for qualitative improvement of evidence-based practice and meta-analysis research by analyzing the qualitative level of the analyzed research. The literature search was conducted using the Research Information Sharing Service, Korean Medical database, and Korean studies Information Service System. Two authors searched, extracted, and reviewed literature using the keywords 'stroke' and 'meta-analysis'. As a result of the AMSTAR-2 quality evaluation of the final 18 studies, 3 studies (16.67%) were 'Moderate', 8 studies (44.44%) were 'Low', and 7 studies (38.89%) were 'Critically Low'. In future research, scientific and objective data selection and extraction process should be performed. It is expected that interest and efforts to improve the quality of meta-analysis research will continue by referring to the contents analyzed in this study as a way to improve the quality of literature.

The purpose of this study was to analyse the qualitative and quantitative characteristics of paper-pencil tests for exploring its appropriateness as a selection tool of the gifted in science. For this purpose, we developed two (internal and external) item analysis frameworks, and applied these frameworks to analyse qualitative characteristics. Also, we analysed the relationship between two characteristics. The results of analysing qualitative characteristics revealed that the portion of items with acceleration context exceeding middle school curriculum level was relatively large, which caused low content validity. Furthermore, there was considerable deviation in content and context by subject matter and year, which caused test unstability. Items measuring knowledge domain was the most prevalent, and too much weight on data interpretation & analysis domain in inquiry process skills. In case of creativity test, the portion of items measuring convergent thinking was much larger than that of divergent or associative thinking. Most of these items were represented by using pictures and tables rather than using graphs. Item types of multiple-choice and short answers were superior to essay types. Discrimination index, on the whole, was appropriate (above 0.3), but item difficulty showed a vast deviation ($0.01{\sim}0.90$). Correlation coefficients among subject matters and test tools were very low, and test reliabilities were also low. Low item difficulty & high discrimination index item types were distinguishable. Items with acceleration context were more discriminating than enrichment context. Implications of developing quality paper-pencil test items in the selection of gifted students are discussed.

The purpose of this study was to analyze the development of social welfare network. The qualitative case study method was utilized from a communities of practice perspective. Depth interviews were conducted among 10 social workers of community welfare agencies who have practiced network activities. Data were analyzed with constant-comparative methods(Strauss and Corbin(1990)). The result are the followings; In incubation stage, the core theme was "collaboration for surmount overcoming difficulties from the bottom". In intergration stage, "acquirement of normative value basement" was emerged. "Reinforcement of solidarity" and "reconfirmation of identity" were drawn as core themes in muturation stage. There were core themes "construction of original image" and "shifting from private connection to public connection" in maintenance stage. Lastly stage a care theme of "qualitative transition" was emerged in transformation.

This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period, evaluation criteria, and evaluation management.

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.

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.

Objective : This study was intended to systematically consider the sensory integration intervention methods offered in Korea for children with autism spectrum disorder and to provide an evidence base for the application of sensory integration interventions. Methods : The subjects of this study were published studies in a national journal for the last 10 years from January 2011 to December 2020. The databases used for the search were RISS and DBpia. The search terms were 'autism', 'autism spectrum', 'sensory integration', and 'intervention'. A total of 10 studies were used in the analysis, which were analyzed at the qualitative and methodological quality of the research evidence and the results were presented according to the PICO (Patient, Intervention, Comparison, Outcome). Results : In the research analysis, the quality level of the evidence was highest at level IV, followed by level II. The methodological quality of the evidence was the most common for 'Good' research, followed 'Fair'. The study subjects were children with autism spectrum disorder and their parents, and the experimental design had the highest frequency of single-subject studies. Interventions have the highest number of studies confirming adaptive behavior and sensory modulation, and the evaluation tools used to measure interventions have the highest frequency of sensory profiles and Canadian occupational performance measures (COPM). All 10 studies used in the analysis showed positive improvements and statistically significant effects on various outcome values from sensory integration interventions. Conclusion : In the recent clinical environment, sensory integration interventions have been continuously conducted in children with autism spectrum disorder. In future research, it is necessary to conduct research on various sensory integration intervention methods and the high quality of the evidence for the application of sensory integration interventions.

남북 정상회담 이후 남북경협 활성화에 대한 기대가 높아지면서 기업의 대북진출에 대한 관심도 크게 증가하고 있다. 우리 기업들이 대북투자에 대하여 커다란 관심을 가지는 이유로는 시장선점, 북한의 낮은 임금 이용, 국내의 유휴설비 이용 등 여러 가지가 있으나 그중 가장 직접적인 요인은 북한의 낮은 임금을 이용하고자 하는 것이라 할 수 있다. 그러나 대북투자의 주요 목적이 북한의 저임 노동력의 활용에 있음에도 불구하고 북한의 임금수준이 얼마나 낮은 것이며, 노동력의 수준은 어떠한지, 또한 이런 상황에서 대북진출시 북한 노동력을 어떻게 활용해야 할 것인지에 대해서는 충분한 검토가 이루어져 있지 않다. 따라서 본 연구에서는 북한 노동력의 임금 및 질적 수준을 분석하고 구체적인 사례에 대하여 살펴본 후 대북진출시 노동력 활용방안에 대하여 검토한다. 우선 북한의 임금수준은 이론적 측면, 동남아 국가 등 경재국과의 비교, 기업의 견해 등을 통해서 살펴볼 때 저렴한 것으로 보기는 어렵다. 질적 수준의 경우에도 일반적으로는 북한 노동력은 우수한 것이라고 인식되고 있으나, 교육수준, 작업규율, 노동생산성 등의 측면에서 분석한 결과 우수한 것으로 판단하기는 곤란하다. 실제 사례에 있어서도 많은 문제를 보이고 있는바, 북한 정책의 문제점, 계약 및 규정에 문제점, 기능 및 교육훈련의 문제점, 근로관습 및 의식의 문제점 등으로 나누어 볼 수 있다. 이러한 상황에서 대북진출은 기대한 만큼의 수익을 거두기가 힘들 것으로 예상된다. 그러나 현재 여건이 어렵다고 무작정 대북진출을 지연할 수도 없고, 기업의 입장에서는 선점 등의 목적으로 현 단계에서 투자를 실행하려고 할 수도 있을 것이다. 또한 일부 분야의 경우에는 이익의 창출이 가능한 사업도 있을 것이다. 본 연구에서는 대북진출에 대비해서 효율적인 북한 노동력 활용방안을 질적 수준 향상방안과 임금관리 방안으로 나누어 살펴보고 있다.
