  • In this paper, we propose a device that can control the primary control surface of an aircraft by recognizing speech commands. The speech command consists of 19 commands, and a learning model is constructed based on a total of 2,500 datasets. The training model is composed of a CNN model using the Sequential library of the TensorFlow-based Keras model, and the speech file used for training uses the MFCC algorithm to extract features. The learning model consists of two convolution layers for feature recognition and Fully Connected Layer for classification consists of two dense layers. The accuracy of the validation dataset was 98.4%, and the performance evaluation of the test dataset showed an accuracy of 97.6%. In addition, it was confirmed that the operation was performed normally by designing and implementing a Raspberry Pi-based control device. In the future, it can be used as a virtual training environment in the field of voice recognition automatic flight and aviation maintenance.

  • Purpose : This study systematically assessed programs self-esteem programs for schizophrenic individuals that have been implemented over the past 10 years in South Korea, with the objective of providing clinical grounds and data for further programs that can be implemented in the Korean environment. Methods : For this study, a data search was conducted from 2012 to 2021, using search terms 'schizophrenia' AND 'self-esteem' among the studies registered in the RISS, KISS, Google Scholar, and National Library of Korea databases. A total of 988 studies were searched, and among them, 40 studies meeting the selection criteria had been taken by reviewing the titles and abstracts. After, 33 studies were excluded according to the exclusion criteria, and finally, the 7 studies were selected. Results : As a result, research into self-esteem programs for schizophrenic individuals has progressed steady, and most studies tend to be non-randomized controlled studies. All studies used the Self-Esteem Scale to evaluate self-esteem. All studies used the Self-Esteem Scale to evaluate self-esteem. The interventions of the selected studies were classified as were social skill programs, cognitive behavioral therapy programs, art therapy programs, and emotional management programs. And among them, the cognitive behavioral therapy programs were the most frequently used (42.8 %). Typically, the majority of the intervention sessions consisted of 11~15 sessions, the frequency of intervention was twice a week, and each session lasted 40~80 minutes were the most (each 57.1 %). In the programs for self-esteem, significant effects were reported for cognitive behavioral and art therapy programs, and there is no significant effect on social skill programs and emotional management programs. Conclusion : Future studies should expand the research scope, both domestically and internationally, and suggest more comprehensive conditions for a literature search by widening the research subject coverage.

  • The incidence of extremity amputation is estimated at about 200,000 cases annually. Over 25% of patients suffer from terminal neuroma or phantom limb pain (TNPLP), resulting in pain, inability to wear a prosthetic device, and lost work. Once TNPLP develops, there is no definitive cure. Therefore, there has been an emerging focus on TNPLP prevention. We examined the current literature on TNPLP prevention in patients undergoing extremity amputation. A literature review was performed using Ovid Medline, Cochrane Collaboration Library, and Google Scholar to identify all original studies that addressed surgical prophylaxis against TNPLP. The search was conducted using both Medical Subject Headings and free-text using the terms "phantom limb pain," "amputation neuroma," and "surgical prevention of amputation neuroma." Fifteen studies met the inclusion criteria, including six prospective trials, two comprehensive literature reviews, four retrospective chart reviews, and three case series/technique reviews. Five techniques were identified, and each was incorporated into a targetbased classification system. A small but growing body of literature exists regarding the surgical prevention of TNPLP. Targeted muscle reinnervation (TMR), a form of physiologic target reassignment, has the greatest momentum in the academic surgical community, with multiple recent prospective studies demonstrating superior prevention of TNPLP. Neurorrhaphy and transposition with implantation are supported by less robust evidence, but merit future study as alternatives to TMR.

  • Objective: This study confirms the safety and efficacy of Banhasasim-tang (BST) against cough through systematic review and meta-analysis. Methods: PubMed, Cochrane, ScienceDirect, Wiley online library, OASIS, KISS, NDSL, RISS, Science and Technology Society Village, DBpia, CNKI, J-STAGE, and CiNii were used as search engines. The search period was from the start of search engine support to June 30. 2020. And search language was not limited. Cochrane's risk of bias (RoB) tool was used to evaluate the quality of the studies. A meta-analysis of the total effective rate (TER), cough symptom score, and spirometry results was performed using the Review Manager program. Results: 6 studies were finally selected. The group using BST showed significant symptom relief, as the odds ratio (OR) value of TER was 5.56 times higher (95% CI: 3.50, 8.82, P<0.0001) compared to the control groups. The reported adverse effects did not occur in the intervention group. In addition, the cough symptom score and spirometry results showed that BST was more effective than Western medicine alone. Conclusion: BST can be expected to relieve cough, and it can be applied to chronic cough that is not treated with existing treatments. However, due to the low quality of the selected articles, additional high-quality RCTs will be required in the future.

  • Background and Objective: The use of potentially inappropriate medications (PIMs) increases the risk of negative health outcomes, including drug-related admissions. Tools for structured medication review have been developed to ensure optimal medication use and safety. Here, we aimed to evaluate medication use review (MUR) tools for community-dwelling older patients. Methods: We performed a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA). We searched PubMed, Embase, and the Cochrane Library from 1991 to 2020, excluding tools that are specifically applied to hospitalized patients or nursing home residents. We identified the most common inappropriate medications, drug-disease interactions, drug-drug interactions and prescribing omissions presented among tools. Results: From among 9,788 identified reports screened, 60 met our inclusion criteria; finally, 27 were eligible for data analysis considering originality and up-to-dateness. Most tools presented explicit criteria (93%), and only one was specific to community-dwelling elderly. The most common PIM was tricyclic antidepressants. Use of diltiazem and verapamil in patients with heart failure and the combination of nonsteroidal anti-inflammatory analgesics and warfarin were the most frequent disease-specific PIM and drug-interaction, respectively. Conclusions: Although several medication review tools have been developed for older adults, specific guidelines for community-dwelling populations remain limited. Furthermore, the list of PIMs differed among available tools. In future, specific but integrating MUR tools need to be developed for clinical practice considering this population.

  • Background: Various oral health management programs in Korea affect the oral health improvement in the elderly Several studies have been conducted to date; however, those studies have not shown uniform results due to the differences in research methods or designs. Hence, this study aimed to review the overall research trends of the reported oral health care programs for the elderly in Korea, verify their effects, and clarify them based on the systematic literature review. Methods: The literature search selected intervention studies that applied the oral health care program for the elderly in Korea from 2001 to 2020. Following the COre, Standard, and Ideal (COSI) models presented by the US National Library of Medicine, we selected databases including Korean studies Information Service System (KISS), ScienceOn, Research Information Sharing Service (RISS), DBpia, PubMed, and Google Scholar. Of the 1,335 studies searched using keywords, titles, and abstracts, 21 were finally selected based on primary and secondary exclusion criteria. Results: The most frequent intervention period was 4 weeks, and the number of interventions varied between 2 and 90 times. As for the type of intervention, 14 studies that conducted both theory and practice were the most frequent. Significant differences in the clinical indicators, such as calculus, halitosis, salivation rate, swallowing function, and dry mouth, were found in most oral health care programs. Conclusion: Based on the results of this study, the intervention program needs further verification using multiple indicators in future studies. In addition, a study extending the intervention period and the number of samples is considered necessary for verifying continuous effectiveness of the intervention program.

  • In this paper, a machine learning-based automatic infographic recommendation system is proposed to improve the existing infographic production method. This system consists of a part that machine learning multiple infographic images and a part that automatically recommends infographics with artificial intelligence only by inputting basic data from the user. The recommended infographics are provided in the form of a library, and additional data can be input by drag & drop method. In addition, the infographic image is designed to be dynamically adjusted according to the size of the input data. As a result of analyzing the machine learning-based automatic infographic recommendation process, the matching success rate for layout and keyword was very high, and the matching success rate for type was rather low. In the future, a study to improve the matching success rate for the image type for each part of the infographic will be needed.

  • The purpose of this research is to explore the phenomenon of the sharing, reuse, and citation of research software. These practices are playing an increasingly important role in scholarly communication. The researchers found that the citation and reuse of research software are currently uncommon or at least not reflected in the Data Citation Index (DCI). Such citation was observed, however, for the newer software in a number of prominent repositories. The repositories Comprehensive R Archive Network (CRAN) and Zenodo received the most formal software citations. The researchers observed both formal and informal forms of citation when researchers reused software. The latter form involves mentioning research software in passing in the main text of articles, while formal citations appear in the references section. In addition, our comparative analysis helps to explain the phenomenon of self-citation of research software.

  • Objectives The purpose of this systematic review is to analyse randomized controlled trials about acupuncture for patellofemoral pain syndrome (PFPS) and evaluate it's pain improvement effect. Methods Studies will be searched from ten databases (Medline/PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure [CNKI], WanFang Data, Citation Information by NII [CiNII], ScienceON, Koreanstudies Information Service System [KISS], KMBASE, and KoreaMed). Participants will be patients diagnosed with PFPS, regardless of cause, gender, age or race, and interventions will be acupuncture, electroacupuncture, dry needling, fire needle, and acupotomy. Other treatments than interventions will be the control group and the main outcome will be reviewed by visual analogue scale (VAS). Results Data will be extracted and assessed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis flow chart and Cochrane risk of bias tools. Meta-analysis will be conducted using random effect model within 95% confidence interval. Conclusions We expect this systematic review to provide useful data about the pain improvements of patellofemoral pain using acupuncture and expect to stimulate and systematize acupuncture treatment on PFPS in the future.

  • Objectives: The aim of this study is to investigate Heart Rate Variability (HRV) characteristics of patients with primary dysmenorrhea at the menstrual phase. Methods: 7 databases (Pubmed, Cochrane library, CNKI, RISS, KISS, OASIS, ScienceON) were searched for eligible studies published before 2021 December. The studies comparing HRV between patients with primary dysmenorrhea and controls were included. A random-effects model was used to evaluate differences of HRV parameters between patients with primary dysmenorrhea and controls. Results: 4 articles were included in this review based on inclusion and exclusion criteria. SDNN (Standard deviation of NN intervals), RMSSD (Square root of the mean squared difference of successive NN intervals), mean PR (Mean of pulse rate), LF (Low frequency), HF (High frequency), was the most frequently used as HRV parameters. RMSSD was significantly lower in patients with primary dysmenorrhea than controls. There was no statistically significant difference of other HRV parameters between patients with primary dysmenorrhea and controls. Conclusions: This study suggests that parasympathetic activity and overall functions of autonomic nervous system might be decreased in patients with primary dysmenorrhea at the menstrual phase. In the future, well-designed clinical studies using HRV and additional meta-analysis should be conducted to obtain a wealth of information about HRV characteristics of patients with primary dysmenorrhea.
