Image noise reduction algorithm performs important functions in light microscopy. This study aims to systematically review the research trend of types and performance evaluation methods of noise reduction algorithm in light microscopic images. A systematic literature search of three databases of publications from January 1985 to May 2020 was conducted; of the 139 publications reviewed, 16 were included in this study. For each research result, the subjects were categorized into four major frameworks-1. noise reduction method, 2. imaging technique, 3. imaging type, and 4. evaluation method-and analyzed. Since 2003, related studies have been conducted and published, and the number of papers has increased over the years and begun to decrease since 2016. The most commonly used method of noise reduction algorithm for light microscopy images was wavelet-transform-based technology, which was mostly applied in basic systems. In addition, research on the real experimental image was performed more actively than on the simulation condition, with the main case being to use the comparison parameter as an evaluation method. This systematic review is expected to be extremely useful in the future method of numerically analyzing the noise reduction efficiency of light microscopy images.

The Brazilian Federal Housing Program "Minha Casa Minha Vida" -PMCMV (My House My Life) is part of a large housing policy to eradicate the housing deficit, estimated at around five million homes in the country. The Ministry for Cities created a network of independent research organizations to evaluate the program, and the PMCMV has attracted many studies. Despite the inherent worth of these individual studies, there is a need for a holistic evaluation. A Systematic Literature Review (SLR) is seen as an important contribution to focus research efforts on the problems identified, to avoid the repetition of studies and to provide novel insights. This article carried out a SLR to map and quantify the types of research and represent a graphic panorama of published studies. Gap spotting was part of the study. In the five-year period from 2010-2014, the SLR identified 1489 bibliographic items. The panorama is categorised according to types of publications, and the analysis of items shows that most studies are concentrated on housing policies, financial questions, urban impacts and Brazilian social development. The results of this SLR raise some new research questions and show opportunities to reduce errors in the housing projects themselves.

Recently, with the increasing of the interest in the integration of medical technology and information communication technology, researches on WBAN (Wireless Body Area Networks) that try to apply sensor network to the human body have been processed actively. The existing sensor network technology has the potential to be used in WBAN, but it has some limitations also. In particular, because the sensors are likely to communicate through each part of the body, it has a very different network environment from the sensor network that uses a free space. Therefore, researches on WBAN have a variety area of study that slightly different from the conventional sensor networks and take into account the characteristics of the body. In this study, we investigate the environmental characteristics of WBAN that are separated from the conventional sensor network, and the research trends of WBAN systematically by using the technique of SLR (Systematic Literature Review) from 2001 around when the concept of WBAN has been introduced. The investigation includes the classification of research and the researcher's features. And the survey results and the outlook for further study are summarized.

Platycodon (Platycodon grandiflorum) is used as a food and medicinal ingredient worldwide, particularly in Northeast Asia. Although a large number of studies have been conducted to determine its medicinal efficacy, there is still a paucity of literature summarizing the clinical activity of Platycodon. In this systematic review, we aimed to summarize the clinical efficacy of Platycodon. All literature describing the clinical efficacy of Platycodon was collected from international databases, and relevant papers were carefully evaluated for eligibility. Data were extracted from the selected papers and quality evaluation was conducted in accordance with the standards provided by the National Institutes of Health (NIH), with all procedures being conducted in accordance with PRISMA 2009 checklist guidelines. After the removal of 342 papers, 644 studies were fully screened for their titles and abstracts, among which, 19 studies were finally selected for full summarization. Extraction of data indicated evidence of the effectiveness of Platycodon in the treatment of respiratory system-related diseases and cancer, and in the provision of immunity. However, we found that the quality and objectivity of evaluation, management of variable factors, sample size, and reproducibility were generally poor. Although Platycodon has shown potential antiviral, antibacterial, anticancer, and antidepressant effects, and promotion of immunity in clinical settings, it was not possible to integrate objective indicators to conduct a meta-analysis due to the lack of literature and insufficient studies. More investigations in the clinical setting should be conducted to confirm the functional effects of Platycodon.

Elbow traumas represent a relatively common condition in clinical practice. However, there is a lack of evidence regarding the most accurate tests for screening these potentially serious conditions and excluding elbow fractures. The purpose of this investigation was to analyze the literature concerning the diagnostic accuracy of clinical tests for the detection or exclusion of suspected elbow fractures. A systematic review was performed using the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines. Literature databases including PubMed, Cumulative Index to Nursing and Allied Health Literature, Diagnostic Test Accuracy, Cochrane Library, the Web of Science, and ScienceDirect were searched for diagnostic accuracy studies of subjects with suspected traumatic elbow fracture investigating clinical tests compared to imaging reference tests. The risk of bias in each study was assessed independently by two reviewers using the Quality Assessment of Diagnostic Accuracy Studies 2 checklist. Twelve studies (4,485 patients) were included. Three different types of index tests were extracted. In adults, these tests were very sensitive, with values up to 98.6% (95% confidence interval [CI], 95.0%-99.8%). The specificity was very variable, ranging from 24.0% (95% CI, 19.0%-30.0%) to 69.4% (95% CI, 57.3%-79.5%). The applicability of these tests was very high, while overall studies showed a medium risk of bias. Elbow full range of motion test, elbow extension test, and elbow extension and point tenderness test appear to be useful in the presence of a negative test to exclude fracture in a majority of cases. The specificity of all tests, however, does not allow us to draw useful conclusions because there was a great variability of results obtained.

Purpose: This study attempted to systematically review the programs of patients with post-traumatic stress disorder in South Korea over the past decade, identify specific methods and effects, and present program guidance guidelines through them. Research design, data and methodology: This study is a systematic literature review, and studies registered in the RISS, NDSL, DBpia, and KmBASE search databases from January 1, 2013 to August 31, 2023 were targeted. Keywords were 'post-traumatic stress disorder', 'program' or 'treatment'. A total of 2,324 documents were searched, and 237 duplicate papers were excluded. After that, the title and abstract were viewed, and 2,058 papers that did not meet the inclusion criteria and exclusion criteria were excluded. In addition, the full text was checked and the final 11 documents were analyzed excluding 18 documents. Results: Among the 11 literatures, 45.45% of randomized control studies and 54.54% of non-randomized control studies were found. As for gender, 41.18% of women, 28.64% of 30-39 years old, and 34.27% of trauma causes were industrial accidents. Programs for patients with post-traumatic stress disorder were classified into art therapy, cognitive behavior therapy, and mindfulness programs, and art therapy was the most used at 45.45%. The sessions of the program were widely applied at 45.45% for 10 sessions and 36.36% for 60 minutes per session. Conclusions: This study has a limitation in that it only analyzed domestic intervention programs within 10 years. However, this study is meaningful in that it is intended to present program guidance guidelines through reviewing domestic programs for post-traumatic stress patients. In the future, it is necessary to conduct research such as expanding the scope of literature review at home and abroad.

Purpose: This systematic review aims to provide an overview of research related to grit among nursing college students in South Korea. Methods: A literature search was done using RISS, KISS, and KCI to identify studies written in Korean from 2010 to 2023. Results: A total of 210 articles were searched, and a final 26 articles were selected in the analysis based on inclusion and exclusion criteria. Three researchers independently coded the characteristics and key content of each paper, including research objectives, methodology, study participants, grit measurement methods, and the relationship between grit and other variables. Subsequently, these coded findings were used to collectively analyze and derive overarching themes through discussion. The analysis results indicated that grit was influenced by factors such as academic major satisfaction, academic performance, and resilience. Grit was found to be a psychological factor affecting nursing students, influencing both major-related competencies and career-related factors. Conclusion: The findings of this review contribute to a deeper understanding of grit within the specific demographic of nursing college students in South Korea and may inform future research and educational practices. In addition, this systematic review provides a comprehensive understanding of the literature on grit among nursing college students in South Korea and serves as a valuable resource for future research and educational interventions in this context.
