As the 4th industrial era is in full swing, the public's interest in related technologies such as artificial intelligence, big data, and block chain is increasing. As artificial intelligence technology is used in various industrial fields, the need for research methods incorporating artificial intelligence technology in related fields is also increasing. Evidence collection among digital forensic investigation techniques is a very important procedure in the investigation process that needs to prove a specific person's suspicions. However, there may be cases in which evidence is damaged due to intentional damage to evidence or other physical reasons, and there is a limit to the collection of evidence in this situation. Therefore, this paper we intends to propose an artificial intelligence-based evidence collection system that analyzes numerous image files reported by citizens in real time to visually check the location, user information, and shooting time of the image files. When this system is applied, it is expected that the evidence expected data collected in real time can be actually used as evidence, and it is also expected that the risk area analysis will be possible through big data analysis.

Purpose: The purpose of this study was to explore nurses' experience of evidence-based nursing practice in general hospitals. Methods: Data were collected from 13 nurses through in-depth interviews about their experiences with evidence-based practice. The research questions were "What kind of evidence are you using in your practice?" and "What are the barriers to and enablers of evidence-based practice that you have experienced?" Qualitative data from field and transcribed notes were analyzed using qualitative content analysis methodology. Results: Major themes of using evidence were identified as 'research as primary valid evidence', 'information from local context and internet as realistic evidence', and 'clinical experience as pragmatic evidence'. Patient experience was not used as evidence in solving nursing problems. Barriers to and enablers of evidence-based practice were linked. They included both external, organizational factors and individual factors. Main issues were 'lack of evidence and poor work environment', and major facilitating factors were 'improving knowledge and skills related to evidence-based practice' and 'communicating and sharing evidence'. Conclusion: The study findings provide useful information for understanding nurses' experience of using external and internal evidence along with their meaning. A multidimensional approach is needed to overcome barriers to and implement evidence-based practice.

In our daily practice, we think about the diagnosis of our patient and get into a situation wherein we have to make a clinical decision. Diagnosis and treatment come from the knowledge and experiences that each dentist should have, but sometimes, we can have doubts on our decisions. "On what evidence did I make such decision? Was that really right?" Drawing our attention these days as a possible answer to this question, evidence-based dentistry seeks to apply the best available evidence gained from the scientific method to medical decision making. To make a good decision, the strength of evidence is assessed. Specifically, randomized controlled trial, systematic review, and meta-analysis are considered the highest level of evidence; cohort study, case control study, case series, animal study, bench test, and biological plausibility follow. With the approach of evidence-based dentistry, we can make objective, scientifically sound clinical decisions. It is also patient-oriented, incorporating clinical experiences and stressing good judgments; thorough and comprehensive, it uses transparent methodology. That is the reason evidence-based dentistry can be better than other assessment methods when we make a clinical decision in modern dentistry.

Purpose: This study aimed to investigate the competency in evidence-based practice, critical thinking disposition, digital literacy, and nursing informatics competence, and to identify the factors influencing the competency in evidence-based practice among nurses. Methods: The participants in this study were 196 nurses from a university hospital in J-city. Data were collected from December 1 to December 30, 2023. The collected data were analyzed with the SPSS 26.0 program using descriptive statistics, independent t-test, one-way analysis of variance, Scheffé test, Pearson's correlation coefficients, and multiple regression analysis. Results: The results showed that the factors influencing the competency in evidence-based practice included nursing informatics competence, critical thinking disposition, digital literacy, and having a master's degree. The participants with a master's degree demonstrated higher competency in evidence-based practice compared to those with a three-year degree or a four-year degree, and a total explanatory power was 53.1%. Conclusion: In this study, critical thinking disposition, digital literacy, and nursing informatics competence were influential factors in competency of evidence-based practice. Therefore, a variety of intervention programs should be developed to enhance the impact of these factors on nurses' competency in evidence-based practice.

This study is to investigate whether young Korean children have understanding for testing hypothesis. Questions explored are; First, do children have notions of testing hypothesis? Or, do they just produce an effect? Second, choosing between conflicting hypotheses, can children distinguish between experiments that would produce conclusive and inconclusive evidence? For this study, 15 first grade and 15 second grade children in elementary school located in Kyunggi area near Seoul participated. Data collection and analysis were based on interviews with children for two weeks. Children were presented two conflicted hypotheses to decide which one is correct through conclusive evidence and inconclusive evidence in the interview. The results showed that children(1st: 93.3%, 2nd: 81.3%) of each grade can distinguish between hypothesis and evidence to do testing hypothesis, and distinguish between conclusive and inconclusive evidence. In conclusion, most young children have understanding of testing hypothesis based on their familiar experiences, so it was possible for them to differentiate hypothesis from evidence in certain situations.

최근 다양한 유형의 증거 분석에서 디지털 증거 분석 기법의 도입이 가속화되고 있으며 중요도가 증가하고 있다. 하지만 개인용 디스크 용량이 커지면서 저장하는 파일의 용량의 수가 증가하면서 전체 데이터를 모두 분석하는 것은 시간과 노력이 많이 소요된다. 대부분의 디지털 증거는 항상 시간정보를 저장하고 있으며, 시간 정보는 디지털 증거 분석에서 가장 중요한 요소 중 하나이다. 하지만 시간 유형이 다양하여 단순히 저장된 시간을 기준으로 사건을 분석하면 잘못된 분석결과를 도출할 가능성이 크다. 따라서 본 논문에서는 다양한 디지털 증거의 시간 유형에 대하여 고찰하고, 하나의 시간 축을 기준으로 디지털 증거 분석을 수행할 수 있는 타임라인 분석 기법에 대하여 설명한다.

Acellular dermal matrices (ADM) are a novel graft. The goal of this systematic review is to evaluate the evidence behind differences in human and porcine ADM, irrelevant of manufacturing method, and to determine if there is enough of an evidence base to change clinical practice. An extensive literature search was performed through MEDLINE and Embase with search terms defining a population, intervention and outcome. Title and abstract exclusion were performed with other exclusion criteria. In 191 articles were found after exclusion of duplicates, with only 29 remaining following exclusions. Ten studies were found to have level I and II evidence (I=3, II=8), of which two were histopathological, one was an animal model, one was a systematic review, and six were clinical. The remaining studies were reviewed and considered for discussion, but did not hold high enough standards for medical evidence. Strong clinical evidence already exists for the use of human ADM, but questions of access, cost, and ethics require consideration of a xenograft. Histopathologically, evidence suggests minimal long-term differences between human and porcine ADM, although there is a short acute immune response with porcine ADM. Clinically, there is limited difference in outcomes, with a small range in effect of different ADM preparations. Considering the effectiveness of ADM in wound healing, more high-level research with appropriate statistical analysis to facilitate a future meta-analysis is recommended to justify a transition from human to porcine ADM.

Purpose: The aim of this study was to identify the individual, job, and organizational factors affecting the individual innovative behaviors among tertiary care hospitals' nurses. Methods: The participants in this study were 230 nurses who have worked more than one year in tertiary care hospitals. Data were collected using self-administered questionnaires that included individual factors (self efficacy, and empowerment), job factors (knowledge and skills for evidence-based practice, and beliefs for evidence-based practice), organizational factors (perceived organizational support), and individual innovation behavior. The SPSS/WIN 25.0 program was used for data analysis which included descriptive analysis, t-test, ANOVA, Scheffé test, Pearson's correlation coefficient, and hierarchical regression analysis. Results: Individual innovative behavior had significant positive correlations with all of individual, job, and organizational factors. The results of hierarchical regression analysis showed that knowledge and skills for evidence-based practice (β=.28, p<.001), self efficacy (β=.25, p=.002), gender (female, β=.23, p<.001), and beliefs for evidence-based practice (β=.17, p=.016) were significant factors influencing on individual innovative behavior. Conclusion: These findings suggest that knowledge, skills and beliefs for evidence-based practice, and self efficacy were linked to individual innovative behaviors. Therefore, education and human resource management improving self efficacy, knowledge, skills and beliefs for evidence-based practice are needed to increase nurses' individual innovative behaviors in tertiary care hospitals.

A Smart Home is a technically expanded from home network that gives us a comfortable life. But still there is a problem such as mal function of devices and intrusions by malicious parties since it is based on home network. The intrusion by malicious parties causes a critical problem to the individual's privacy. Therefore to take legal actions against to the intruders, the intrusion evidence collecting and managing technology are widely researched in the world. The evidence collecting technology uses the system which was damaged by intruders and that system is used as evidence materials in the court of justice. However the collected evidences are easily modified and damaged in the gathering evidence process, the evidence analysis process and in the court. That's why we have to prove the evidence's integrity to be valuably used in the court. In this paper, we propose a mechanism for securing the reliability and the integrity of digital evidence that can properly support the Computer Forensics. The proposed mechanism shares and manages the digital evidence through mutual authenticating the damaged system, evidence collecting system, evidence managing system and the court(TTP: Trusted Third Party) and provides a secure access control model to establish the secure evidence management policy which assures that the collected evidence has the corresponded legal effect.

Objective : The purpose of this study is to work on the problems and on the direction of the study regarding the evidence-based study of Acupuncture. Methods : We reviewed the PubMed electronic database. Eight articles of systematic review without meta-analysis and six articles without meta-analysis were selected. Results : In the study of eight articles of systematic review without meta-analysis, there were two articles on effectiveness of acupuncture and one on non-effectiveness of acupuncture. Four articles were about the changes according to the quality of randomized controlled trials. Also, one article was about the side-effect of acupuncture. In the study of six articles of systematic review with meta-analysis, there were two articles on Odds Ratio, two on Relative Risk, one on number-needed-to-treat, and two on 18 predefined methodological criteria. Conclusion : As the quality of RCTs was high, positive response decreased and as the quality of RCTs was low, positive response increased. For the study of evidence-based acupuncture, it is necessary that we conduct research on well-planned placebo acupuncture, large sample size, statistical method, method of searching and assessing literature and method of meta-analysis.
