The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) Photographs, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics are needed for social studies teachers.

The purpose of this study was to examine research trends in articles of preschooler peer relationships carried in domestic academic journals. This was done in an attempt to suggest alternative directions for peer relationship studies in the early childhood education sector and lay the foundation for future studies. 131 articles that appeared in seven domestic academic journals related to early childhood education were selected and analyzed in order to better understand the general trends in the filed and the specific trends in terms of their content and methods. Our results indicate that the observation method was most common in the quantitative studies, and participant observation was most prevailent among qualitative studies. As for instrumentation, international instruments were most widely utilized, and the most dominant analysis method was descriptive statistics. In terms of reliability, internal consistency was checked most often, however, the majority of the studies failed to provide any information on validity and post-hoc analysis.

Ginseng has been reported to reduce the risk of cancer in diverse organs, including the lip, oral cavity, pharynx, larynx, esophagus, lung, liver, pancreas, ovary, colon, rectum, and stomach, as demonstrated in clinical and epidemiological studies. studies, base on which findings, Panax ginseng has been classified as a "non-organ-specific cancer preventive." However, the recent keen interest in traditional medicinal herbs has been frequently questioned, about exact mode of action and the use of panaceic compounds has been a prime issue discussed in terms of complementary and alternative medicine. Several in vitro and in vivo studies have shown the mitigating effects of Korean red ginseng on Helicobacter pylori (H. pylori)-associated atrophic changes and carcinogenesis; However, evidence-based medicine, consisting of large-scale or well designed clinical studies, is still warranted whether Korean red ginseng is to be recognized as an essential therapeutic strategy regarding a "H. pylori-associated gastric cancer preventive." Specifically, comprehensive clinical trials of Korean red ginseng are needed to demonstrate that mucosal regeneration in patients with atrophic gastritis is feasible using Korean red ginseng supplements after the eradication of H. pylori infection. Ginseng is a good example of a natural herb and its ubiquitous properties may include the reduction or delay of inflammation carcinogenesis. Korean red ginseng contains ample amounts of active ginsenosides and we have demonstrated their effects in in vitro and in vivo studies with positive outcomes. In this review, the quantitative and qualitative benefits of Korean red ginseng in the treatment of H. pylori infection are described.

This study aims to understand the research trends in visiting nursing through an analysis of 282 research papers published in Korean journals between 1993 and 2018. The number of research papers has consistently increased since 1993 while it slightly decreased in 2014-2018. Of the three types of visiting nursing in Korea, more than 50% of the studies(154, 53.5%) were conducted for hospital based home care services. For the research topics, many studies addressed visiting nursing services(40, 13.8%) and program and technology development of visiting nursing(38, 13.1%). Also, there were many quantitative studies(269, 95.4%) compared to qualitative(9, 3.2%) or mixed methods(4, 1.4%) studies. The study findings suggested the needs for further studies that develop programs for patients and strengthen competencies of visiting nurses. Also, more experimental, qualitative, or mixed methods study designs need to be applied.

The purpose of this study was to analyze research trends on subjective well-being in the elderly. To this end, 49 academic papers (general characteristics, research subjects, number of researchers, research variables, and research methods) retrieved through RISS were classified according to criteria. One or two research papers have been steadily published starting with two in 1988, but a slight increase in 2009 and 2010, four each, and five in 2014, respectively. By sample size, 201 to 300 were the most frequent with 14 studies. Quantitative studies were the most common as a research method, but 2 qualitative studies and 2 longitudinal studies were identified through trend analysis. It was confirmed that there are many variables related to physical health such as leisure sports, physical activity, sports for all, dance sports, and mobility discomfort as research topics. The number of studies on the elderly should be increased, and the need for qualitative research to explore the life experiences and meanings of old age is suggested.

The growing interest in the privacy paradox involving discussions about discrepancy between attitude and behavior led to an increase in the number of studies on the topic. An in-depth theoretical review of the privacy paradox is essential to promote qualitative growth of domestic research in the privacy paradox. In this study, we conducted literature review of existing domestic studies in the privacy paradox. The results of this study showed that the quantity and the quality of research showed marked improvement. Earlier studies primarily focused on the existence of the privacy paradox phenomenon, but existing studies on the causes of the phenomenon gradually increased. Despite the use of various methodologies and analytical tools to investigate the causes of the privacy paradox, research in privacy paradox remains in its infancy. Further efforts are needed to achieve qualitative growth, and further studies should be conducted to introduce the behavioral economic approach. This approach posits that bounded rationality could contribute to a clear understanding of the privacy paradox and the academic development of the privacy field.

This study focuses on the development of simple qualitative indicators for evaluating and selecting innovation leading companies that challenge National Award. Another purpose of this study is to complement the aspect in which the innovative or value of the companies' products, technologies, and services is only quantitatively evaluated. Existing evaluation indicators of national award have too many evaluation items and were not suitable for innovation-based company evaluation. The research approach is to select category for developing qualitative indicators based on previous studies and TF discussion. From the input-process-output-outcome point of view, we have set up an indicator system as a series of flows. Finally, five categories such as creativity, system excellence, customer value, performance, and ripple effects are selected as qualitative indicator. For these selected indicators, conceptual definitions and the main points of evaluation are described. And the system level evaluation and the ADLI approach are presented for reference. The appendix also includes examples of qualitative and quantitative evaluation of real companies using these indicators. However, this study implies the possibility that the evaluation results may vary depending on the level and perspective of the evaluator. We hoped that detailed research on candidate indicators that can be used as qualitative indicators and research on the development of mixed indicators(qualitative and quantitative) will continue in the future.

Objective: To evaluate the diagnostic performance of chest computed tomography (CT)-based qualitative and radiomics models for predicting residual axillary nodal metastasis after neoadjuvant chemotherapy (NAC) for patients with clinically node-positive breast cancer. Materials and Methods: This retrospective study included 226 women (mean age, 51.4 years) with clinically node-positive breast cancer treated with NAC followed by surgery between January 2015 and July 2021. Patients were randomly divided into the training and test sets (4:1 ratio). The following predictive models were built: a qualitative CT feature model using logistic regression based on qualitative imaging features of axillary nodes from the pooled data obtained using the visual interpretations of three radiologists; three radiomics models using radiomics features from three (intranodal, perinodal, and combined) different regions of interest (ROIs) delineated on pre-NAC CT and post-NAC CT using a gradient-boosting classifier; and fusion models integrating clinicopathologic factors with the qualitative CT feature model (referred to as clinical-qualitative CT feature models) or with the combined ROI radiomics model (referred to as clinical-radiomics models). The area under the curve (AUC) was used to assess and compare the model performance. Results: Clinical N stage, biological subtype, and primary tumor response indicated by imaging were associated with residual nodal metastasis during the multivariable analysis (all P < 0.05). The AUCs of the qualitative CT feature model and radiomics models (intranodal, perinodal, and combined ROI models) according to post-NAC CT were 0.642, 0.812, 0.762, and 0.832, respectively. The AUCs of the clinical-qualitative CT feature model and clinical-radiomics model according to post-NAC CT were 0.740 and 0.866, respectively. Conclusion: CT-based predictive models showed good diagnostic performance for predicting residual nodal metastasis after NAC. Quantitative radiomics analysis may provide a higher level of performance than qualitative CT features models. Larger multicenter studies should be conducted to confirm their performance.

This study compared Korean and American children on scaffolding by peers during dramatic play. Thirty Korean and twenty American 5-year-old kindergarteners participated. The data were analyzed by Spradly's (1980) Developmental Research Sequence (DRS), using qualitative methods. The results showed that the categories of scaffolding (theme and communication) occurred more frequently among American children than among Korean children. In both cultures, more capable peers scaffolded children during dramatic play and were able to extend the dramatic play.
