수학교육 연구 공동체에서는 모델링 활동을 통한 수학 학습에 대한 논의들이 지속되어 왔다. 모델링 활동은 대안적인 수학 교수 학습 방법으로 논의되어 왔으나, 모델링 활동을 통하여 이루어지는 수학 학습은 어떠한 성격을 갖는지, 그리고 이는 어떠한 과제 설계와 수업 실행을 통하여 달성할 수 있는지에 대한 합의점은 도출되지 못한 실정이다. 모델링 활동을 통한 수학 학습을 시도해 온 선행 연구들의 논의로부터, 본 연구에서는 모델링 활동이 메타수준의 수학적 담론 생성과 메타규칙의 변화를 포함하는 메타수준 학습을 촉진할 수 있을 것으로 판단하였다. 이에 본 연구에서는 메타수준 학습을 촉진할 수 있는 모델링 과제 설계와 수업 실행 방안을 도출하고, 이를 실행하여 수학 교수 학습에서 모델링 활동의 잠재력을 확인하는 데 목적을 둔다.

Objectives : Lung cancer is one of the most common cancer and the leading cause of cancer deaths worldwide. This study aimed to evaluate the role of acupuncture as an adjunctive therapy for lung cancer. Methods : We conducted a systematic review and meta-analysis on the role of acupuncture therapy in lung cancer treatment by electronic and manual searching in ninedatabases, including PubMed, Cochrane library, Embase, Korean databases, and Chinese medical databases. Results : A total of 21 trials were included in the meta-analysis. The study results showed that acupuncture therapy had significant efficacy in immuneregulation, including CD3 andCD4. Further analysis revealed that acupuncture therapy significant improvements in quality of life, including Karnofsky performance status(KPS)score, functional assessment of cancer therapy-lung cancer subscale (FACT-L) and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). In addition, the pooled studies also showed that acupuncture therapy reduced cancer pain and chemotherapy-induced nausea and vomiting. Conclusions : Our study provides moderate evidence of the efficacy of the acupuncture therapy in the treatment of lung cancer.

Purpose: This study identified the effects of physical therapists on the quality of life when applying exercise-based movement techniques to breast cancer survivors. Methods: To conduct meta-analysis, 186 RCT studies were searched in five databases (RISS, Pubmed, CINAHL, Medline, and Cochrane Library), without limitation, for the year of publication, and papers published in April 2018 were selected. Four studies met the inclusion criteria and were selected for meta-analysis based on the risk of bias. The basic demographic data, athletic characteristics, and outcome data were extracted from all included clinical trials. The data were analyzed using the RevMan 5.2 program. Results: As a result of meta-analysis, exercise-based movement techniques applied by the control group (Pilates, yoga, tai chi, and qigong) or physical therapists showed no significant difference in the impact on the quality of life of breast cancer survivors. Conclusion: In this study, exercise-based movement techniques mediated by control groups or physical therapists showed no significant difference in the quality of life of breast cancer survivors, but the types and duration of exercise in each study varied, and the number of subjects was small. Considering randomized studies, more randomized studies will be needed to draw conclusions.

Purpose: The purpose of this study was to provide data about the risk factors related to falls among elderly patients with dementia using meta-analysis. Methods: Key words used for search through electronic database (CINAHL, PubMed, Ovid-MEDLINE, RISS, KISS, DBPIA, National Assembly Library) included 'dementia', 'Alzheimer', 'fall'. Twenty studies met the inclusion criteria for the meta-analysis and 'R' version 3.2.2 was used to analyze the correlated effect size. Results: Study results showed that risk factors related to falls were identified as the demographic (age, gender, education), dementia-related (disease duration, cognition), physical (body mass index, walking, balance, activity of daily living, use of walking aids, number of medications including psychotropic drugs, musculoskeletal problems, parkinsonism, comorbidity), psychological (neuropsychiatric symptom, depression), environmental (Physical environment), and fall-related (fall history, high risk group of fall) factors. The effect size of risk factors such as high risk group of fall (r=.35), use of walking aids (r=.33), depression (r=.31), psychotropic drugs (r=.27), Musculoskeletal problems (r=.25) were higher than the other risk factors. Conclusion: Based on the findings of this study, strategies to improve elderly patient's depression, intensive care for high risk group of fall, and adequate training with walking aids are needed for prevention of falls in elderly patients with dementia.

Purpose: The purpose of this study was to determine whether walking exercise improved physical function in elderly people using meta-analysis. Methods: Medical and nursing literature databases were searched to identify the studies on the effectiveness of walking exercise on physical function. In the databases, there were 16 articles reporting 21 interventions. Overall effect sizes for three outcome variables, elders' physical function in lower limb muscle endurance, whole body endurance and upper body flexibility, were calculated. Effects of study characteristics on outcome variables were analyzed. Results: The meta-analysis showed that walking exercise generally had positive effects on CST (chair stand test), 6MW (6 min walking), and SRT (standing or sitting reach test) with overall weighted effect sizes of 1.06, 0.41 and 0.29 respectively. This study also showed that the chronic disease status of the elders, intervention methods, and type of residence had different effects on CST, 6MW and SRT. Conclusion: The results indicate that walking exercise improves physical function in elders. Walking exercise which can be done at any time and any location is indeed a very effective exercise for elderly people.

Purpose: The purpose of this study was to integrate and synthesize findings from qualitative studies exploring male students' experiences of adapting to nursing education programs so as to obtain further understanding of the phenomenon. Methods: The meta-synthesis process was primarily guided by Noblit and Hare's approach, which consists of four stages including searching, appraisal of an individual study's quality, data extraction for analysis, and meta-synthesizing the results. Results: Findings from the literature reviewed were synthesized into six themes: 1) extraordinary choice based on job stability and gender scarcity; 2) unexpected feeling of marginalization as minority far apart from the mainstream; 3) assimilation and negotiation for relational adaptation through perspective shift; 4) fortifying the vision and identity as nursing students by meaning making for adapting to the nursing major; 5) mutual support among colleague male students; and 6) serving in the military as way of hiding out and achieving maturation. Conclusion: The findings illustrate that nursing education programs need practical changes promoting male students' adaptation to the program itself as well as preparation to be a professional nurse in the future.

Many different intervention methods have been developed to resolve the problem of clients, but research studies evaluating the effectiveness of such practices can be overwhelming to social workers because of the conflicting results of them. In this study, meta-analysis was used to make sense of this research, offering the general effect size of social work practice. Meta-analysis can answer the question, "how effective is the intervention?" beyond the question, "is the intervention effective?". It can integrate the fragmentated results of research studies and provide the guidelines for best practice. Combining the results of the 16 research studies, this study computed the general effect size of social work interventions. The mean d index was. 6636 (95 percent confidence interval of .5355, .8018). Conversion to Cohen's $U_3$ statistics allows for the inference that three-fourths (74.7%) of the clients who participated in an intervention group did better than the average clients of non-intervention group. This means that social work interventions are practically helpful to seven of every 10 clients who experience them. In conclusion, this study recommended the usefulness of meta-analysis, which can provide the intervention strategies based on empirical research and guide the best approaches.

Recently, in the research on online environment such as e-commerce, and internet banking, the conceptual discussion about trust and risk in an effort to explain a user's behavior is briskly underway. Most of the research on trust and risk are setting up causal relationship without clearly establishing the relationship between trust and risk. Accordingly this study conducted a meta-analysis in order to consider the relationship between trust and risk and to take a look at the difference in causal relationship. This study includes a total of 18 research papers which are setting up the causal relationship between trust and risk in online environment among the research papers published in domestic academic journals since 2000. Result of the meta-analysis, showed that the effect size was -0.367 in the path from trust to risk; -0.131 in the path from risk to trust; -0.276 in the bidirectional path between trust and risk. In addition, this study was able to confirm through literature review that there appeared a high effect of path in case where trust and risk were measured by an uni-dimensional concept than by a multi-dimensional concept.
