  • Background and objective: The ongoing COVID-19 pandemic restricted daily life, forcing people to spend time indoors. With the growing interest in mental health issues and residential environments, 'pet plants' have been receiving attention during the unprecedented social distancing measures. This study aims to analyze the change in trends of pet plants before and during the COVID-19 pandemic and provide basic data for studies related to pet plants and directions of future development. Methods: A total of 2,016 news articles using the keyword 'pet plants' were collected on Naver News from January 1, 2018 to August 15, 2019 (609 articles) and January 1, 2020 to August 15, 2021 (1,407 articles). The texts were tokenized into words using KoNLPy package, ultimately coming up with 63,597 words. The analyses included frequency of keywords and topic modeling based on Latent Dirichlet Allocation (LDA) to identify the inherent meanings of related words and each topic. Results: Topic modeling generated three topics in each period (before and during the COVID-19), and the results showed that pet plants in daily life have become the object of 'emotional support' and 'healing' during social distancing. In particular, pet plants, which had been distributed as a solution to prevent solitary deaths and depression among seniors living alone, are now expanded to help resolve the social isolation of the general public suffering from COVID-19. The new term 'plant butler' became a new trend, and there was a change in the trend in which people shared their hobbies and information about pet plants and communicated with others in online. Conclusion: Based on these findings, the trend data of pet plants before and after the outbreak of COVID-19 can provide the basis for activating research on pet plants and setting the direction for development of related industries considering the continuous popularity and trend of indoor gardening and green hobby.

  • Objectives: The persistence and unpredictability of coronavirus disease (COVID-19) and new measures to prevent direct medical intervention (e.g., social distancing and quarantine) have induced various psychological symptoms and disorders that require self-treatment approaches and integrative treatment interventions. To address these issues, the Korean Medicine Mental Health (KMMH) center developed a field manual by reviewing previous literature and preexisting manuals. Methods: The working group of the KMMH center conducted a keyword search in PubMed in June 2021 using "COVID-19" and "SARS-CoV-2". Review articles were examined using the following filters: "review," "systematic review," and "meta-analysis." We conducted a narrative review of the retrieved articles and extracted content relevant to previous manuals. We then created a treatment algorithm and recommendations by referring to the results of the review. Results: During the initial assessment, subjective symptom severity was measured using a numerical rating scale, and patients were classified as low- or moderate-high risk. Moderate-high-risk patients should be classified as having either a psychiatric emergency or significant psychiatric condition. The developed manual presents appropriate psychological support for each group based on the following dominant symptoms: tension, anxiety-dominant, anger-dominant, depression-dominant, and somatization. Conclusions: We identified the characteristics of mental health problems during the COVID-19 pandemic and developed a clinical mental health support manual in the field of Korean medicine. When symptoms meet the diagnostic criteria for a mental disorder, doctors of Korean medicine can treat the patients according to the manual for the corresponding disorder.

  • Purpose: In order to improve the audit quality of a company, an in-depth analysis is required to categorize the audit report in the form of a text document containing the details of the external audit. This study introduces a systematic methodology to extract keywords for each group that determines the differences between groups such as 'audit plan' and 'interim audit' using audit reports collected in the form of text documents. Methods: The first step of the proposed methodology is to preprocess the document through text mining. In the second step, the documents are classified into groups using machine learning techniques and based on this, important vocabularies that have a dominant influence on the performance of classification are extracted. In the third step, the association rules for each group's documents are found. In the last step, the final keywords for each group representing the characteristics of each group are extracted by comparing the important vocabulary for classification with the important vocabulary representing the association rules of each group. Results: This study quantitatively calculates the importance value of the vocabulary used in the audit report based on machine learning rather than the qualitative research method such as the existing literature search, expert evaluation, and Delphi technique. From the case study of this study, it was found that the extracted keywords describe the characteristics of each group well. Conclusion: This study is meaningful in that it has laid the foundation for quantitatively conducting follow-up studies related to key vocabulary in each stage of auditing.

  • 감성 지능형 컴퓨팅은 컴퓨터가 학습과 적응을 통하여 인간의 감성을 처리할 수 있는 감성인지 능력을 갖는 것으로 보다 효율적인 인간과 컴퓨터의 상호 작용을 가능하게 한다. 감성 정보들 중 시각과 청각 정보인 음악 이미지는 짧은 시간에 형성되고 기억에 오랫동안 지속되기 때문에 성공적인 마케팅에 있어서 중요한 요인으로 꼽히고 있으며, 인간의 정서를 이해하고 해석하는데 있어서 매우 중요한 역할을 한다. 본 논문에서는 사용자의 감성키워드(짜증, 우울, 차분, 기쁨)를 고려하여 매칭된 음악과 이미지를 검색하는 시스템을 구축하였다. 제안된 시스템은 인간의 감성을 4단계 경우로 상황을 정의하며, 정규화 된 음악과 이미지를 검색하기 위해 음악 이미지 온톨로지와 감성 온톨로지를 사용하였으며, 이미지의 특징정보를 추출, 유사성을 측정하여 원하는 결과를 얻게 하도록 하였다. 또한, 이미지 감성인식정보를 분류하기위해 대응일치분석과 요인분석을 통한 성컬러와 감성어휘를 하나의 공간에 매칭하였다. 실험결과 제안된 시스템은 4가지 감성상태에 대해 82.4%의 매칭율를 가져올 수 있었다.

  • Purpose: The purpose of this study was to identify the trends in studies published in Journal of Korean Critical Care Nursing (JKCCN) from 2008 to 2013. Methods: A total of 65 studies published between 2008 to 2013 were reviewed using criteria developed by researchers. Results: Approximately 36% of studies were conducted with patients. Intensive care unit (ICU) was the most popular site as the study setting. Among 59 research papers, 42.4% were approved by institutional review board (IRB). Quantitative studies were 78.6%, while qualitative studies were 4.6%. The research designs for the quantitative studies were survey (52.3%), quasi-experimental (16.9%), and so on. There was no randomized controlled trial. The most frequently used methods to provide nursing intervention was education. In addition, "nurse" and "ICU" were most commonly used keyword. Conclusion: Considering the low rate of IRB approval, more stringent application of research ethics is necessary to improve the quality of JKCCN. In addition, more randomized controlled trials should be encouraged to support evidence-based practice in critical care.

  • 본 논문에서는 문서 영상의 그림 영역에서 통계적 분석을 통한 단어 영상을 추출하는 방법을 제안한다. 제안 방법은 그림 영역의 구성 요소를 문자 성분과 그래픽 성분으로 분류하기 위하여 연결요소에 대한여 통계적 분석 방법인 상자그림 분석을 적용하고, 분류된 문자 성분들에 대하여 지역적 밀집도를 분석하여 문자 영역을 추출한다. 추출된 문자 영역에서 투영 히스토그램 분석을 통하여 문자열을 추출하고, 문자열을 단어단위 영상으로 분리하기 위하여 투영 히스토그램 분석과 갭 군집화, 특수 기호 검출 등을 수행한다. 제안 방법은 임계값의 사용 대신에 그림 영역의 구성 요소들에 대하여 통계적 분석을 수행하기 때문에 그림의 형태 변화에 민감하지 않으며, 지역적 밀집도 분석으로 보다 정확한 문자 영역을 추출하였다. 또한 제안 방법의 응용 분야인 주제어 검색을 위한 오프라인의 전처리에 해당하는 문서 영상의 단어단위 영상 추출에 적용하여 제안 방법에 대한 연구의 필요성을 제시하였다.
