  • Purpose: This study aims to investigate how the online review usefulness affect consumers' shopping behavior in non-face-to-face shopping, which is now very common format of shopping environment after COVID-19 pandemic. Factors influencing online reviews were determined as quantity of review, agreement of review and characteristic of review based on research by existing researchers. Research design, data, and methodology: Customers in their teens to 60s who had experience of checking online reviews and purchasing products were surveyed using a Google questionnaire form from January 15, 2022 to February 19, 2022. To verify the validity and reliability of the research model, confirmatory factor analysis and discriminant validity analysis were conducted. In addition, the causal relationship between factors was verified through path analysis. Results: As a result, quantity of review and agreement of review had a statistically significant effect on review usefulness. However, characteristic of review did not have a statistically significant influence on review usefulness. And review usefulness had a statistically significant effect on attitude and purchase intention. Conclusions: This study investigated the factors affecting usefulness of online reviews and empirically analyzed the effects of online reviews on consumer attitudes and purchase intentions providing practical and theoretical implications for corporate online review management.

  • Interests on collaborative research and academic relationship among researchers have been increased. Collaborative researchers can maximize productivity, time and cost savings, and reduce the risk of research. An empirical study on the research productivity of co-authors' network and review efficiency of the reviewer network was conducted based on co-author networks and reviewer networks in Korea Society of IT Service. This study aims to find the characteristics of the co-author and reviewer networks, and to analyze research productivity and review efficiency in order to draw some implications. The meaning of interactions among professional groups was analyzed. Research productivity index was calculated using 728 authors' papers submitted to the society. In order to verify the effects of indicators of social network analysis on research productivity and review efficiency, correlation and regression analyses were used. As a result, the indicators of network centrality did not affect the review efficiency, but affect the research productivity.

  • Background: Since December 2010, online computerized prospective drug utilization review (pDUR) has been implemented in Korea. pDUR involves the review of each prescription before the medication is dispensed to the individual patient. The pDUR is performed electronically by Health Insurance Review & Assessment Service (HIRA), which is a Korean governmental agency, and then HIRA provides medical institutions and pharmacies with information that can be helpful to them in preventing potential drug problems such as drug/drug interactions or ingredient duplication. The aim of this study was to assess the impact of the Korean pDUR implementation on the proportion of drug-drug interactions (DDIs) using claims data from HIRA. Methods: A before-after comparison of the prevalence of DDIs between prescription was conducted, using HIRA administrative claims data of medical institution from January 2010 to December 2011. The analysis unit was the prescription issued and pairs before and after. The main outcome measures were the proportion of DDIs within- (control group) or between- physician encounters. To examine the difference, a paired t-test was applied. Results: We found that DDIs proportion between prescription decreased significantly (t=3.04, p=0.0026) after the implementation of pDUR, whereas there is no significant reduction within prescription (t=1.15, p=0.2518). With respect to the prevalence of DDIs between drug groups, the most dramatic reduction was occurred between 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors and anti-fungal agents. Conclusion: It seems effective that giving a direct feedback to prescribers by a prospective DUR. Further research is needed to assess the impact of DUR to final outcomes such as hospitalization.

  • Scientists planning research that involves the use of animals are required by international and/or national law to examine the possibilities for the implementation of Replacement, Reduction and/or Refinement (the Three Rs principles of Russell and Burch) in experiments for research, testing, and education. There are two Korean laws legislating humane use of animals and ethical review prior to animal experiments. This report reviews current practice of the literature search by the researchers and protocol review by the Institutional Animal Care and Use Committees on the Replacement, Reduction and Refinement alternatives in Korea. The promotion and protection of the laboratory animals are one of the core competencies of investigators exploring the ethical conduct of research and good science.

  • To suggest future directions for the improvement in the Institutional Review Board (IRB) review process and efficient operation of IRB, we have analyzed the IRB review results from 460 new research proposals submitted to the Review by the Convened IRB of the Keimyung University Dongsan Hospital IRB from January 2019 to July 2021. IRB is an independently established institutional committee to protect the human subjects by reviewing the research protocol in ethical as well as scientific aspects, so it is necessary to continuously contemplate the ethical versus scientific dilemma of 'what is ethical or scientific and what can actually protect human subjects.' Particularly, in this process, it is necessary to consider diverse ways to strengthen self-supervision through continuous Internal Audit rather than simple reporting outcomes. In addition, if it does not directly affect the protection of the human subjects, the discussion with the committee members is needed so that the comments such as administrative and typographical errors can be reduced as much as possible. Furthermore, as statistical analysis methods can have a significant impact on the safety of human subjects, if a legal basis and/or support related to statistics is provided for the composition of IRB members, a more specialized IRB review will be achieved.

  • Purpose: This paper was written to introduce methods of using the research ethics committee (RES) from requesting the initial review to reporting the close-out for nursing researchers. Methods: General ethical principles were described by reviewing the 'Bioethics and Safety Act' and other related guidelines, and constructing some questions and answers. Results: The results were composed of three parts; definition of RES, steps in using RES, and archiving. The 7 steps for using RES were; identifying whether the study needed to be reviewed, by the RES identifying whether the study could be exempted, requesting the initial review after preparing documents, requesting the re-review, requesting an amendment review, requesting a continuing review and reporting the close-out. Conclusion: Nursing researchers need to receive RES approval before starting nursing research involving human subjects. Nursing researchers are urged to use the steps reported in this paper to receive RES approval easily and quickly.

  • The strengthening of Institutional Review Board (IRB) and Human Research Protection Program (HRPP) for clinical research on advanced regenerative medicine reflecting the 3 Principles of the Belmont Report (Respect, Beneficence, Justice) is very important. The research institution IRB should naturally be in charge of managing the clinical research process. And it is crucial to reinforce HRPP for the protection of research subjects in institutions conducting advanced regeneration clinical research. So, it is needed to establish a Protection System for Advanced Regenerative Medical Research Subjects composed of clinical research management communication system for advanced regenerative medicine between KAIRB (Korean Association of IRB) of research institutes and National Management Agency for Advanced Regenerative Medical Research. In advanced regenerative medicine clinical research to verify safety and efficacy of the investigational drugs to the subjects with rare and incurable diseases rather than to treat the patients, it is hoped that a management system that guarantees the scientific characteristics of research and the rights of research subjects would be well organized and operated.

  • This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.
