Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had significant physical and psychological impacts on registered nurses (RNs). This study aimed to identify long COVID symptoms and their associated factors specifically among RNs. Methods: This descriptive correlational study’s sample comprised 189 nurses (31.57±5.98 years, 93.7% female) in Korea. Self-reported long COVID symptoms were assessed using the COVID-19 Yorkshire Rehabilitation Scale. Data were collected from December 31, 2022, to January 13, 2023, using the online survey method and were analyzed using independent t-test, Wilcoxon signed-rank test, one-way ANOVA, Pearson’s correlation, and a multiple linear regression analysis with the IBM SPSS Statistics 26.0 program. Results: A total of 179 participants (94.7%) experienced one or more long COVID symptoms. The most prevalent symptoms were weakness (77.8%), fatigue (68.3%), breathlessness (67.7%), cough/throat sensitivity/voice change (50.3%), and sleep problems (50.3%). The factors related to long COVID symptoms were marital status, type of institution, working time, acute COVID-19 symptoms, and vaccination status. The quarantine period (β=.26, p<.001) and the nursing workforce after COVID-19 (β=-.17, p=.018) were significantly associated with long COVID symptoms (Adjusted R²=.33). Conclusion: Providing comprehensive recognition is necessary for the understanding of long COVID symptoms and their associated factors among nurses and could promote a long COVID symptom management education program targeted at nurses. Moreover, it could facilitate effective nursing care and education plans for long COVID patients.

본 연구에서는 텍스트 마이닝 분석을 통해 한국 사회에서 행복과 불행이 갖는 의미를 탐색하였다. 자료수집 및 분석을 위하여 온라인 뉴스 포털에서 Word2Vec과 TF-IDF 방법을 사용하여 ‘행복’ 및 ‘불행’ 키워드와 유사한 단어를 추출했다. 또한 K-LIWC 사전을 사용하여 행복 및 불행과 연관된 단어들의 감성 속성에 대해 알아보았다. TF-IDF 분석 결과, 행복과 불행은 사회적 요인과 해당 년도의 사회적 이슈들과 각각 높은 관련성이 있는 것으로 관찰됐다. Word2Vec 분석에서는 ‘희망’이 6년 연속으로 행복과 유사성이 높은 단어로 나타났다. K-LIWC 분석에서 ‘돈재정적이슈’, ‘학교’, ‘의사소통’은 행복 및 불행과 모두 관련성이 높았다. 그밖에 ‘몸 상태와 증상’이 불행과 높은 관련성이 있는 범주로 나타났다. 이러한 결과를 바탕으로 본 연구의 의의, 제한점 및 후속연구에 대한 필요성을 논의하였다. The purpose of this study is to explore the meaning of happiness and unhappiness in Korean society through text mining analysis. Similar words with keywords(happiness/unhappiness) from online news portal are extracted using Word2Vec and TF-IDF method. We also use the K-LIWC dictionary to perform the sentiment analysis of words associated with happiness and unhappiness. In TF-IDF analysis, happiness and unhappiness are highly related to social factors and social issues of the year. In Word2Vec analysis, Hope has been similar with happiness for six years. In K-LIWC analysis, ‘money/financial issues’, school, communication is highly related with happiness and unhappiness. In addition, physical condition and symptom is highly related to unhappiness. Implications, limitations, and suggestions for future research are also discussed.

This study was conducted to investigate the anti-aging effects and cell toxicity of water extracts obtained from Ailanthi radicis cortex at 95℃. The amount of total flavonoid and polyphenol compounds was 4.80 mg/g and 136.89 mg/g, respectively. The astringent effect as a measure of pore tightening activity of the Ailanthi radicis cortex extract was 36.34% at 100 μg/mL. The tyrosinase inhibition as a measure of whitening activity was 53.20% at a concentration of 1,000 μg/mL. The collagenase and elastase inhibitory activities as a measure of anti-wrinkle activity were 48.97% and 18.02% at 1,000 μg/mL, respectively. Cell viability, as determined using the MTT assay, Ailanthi radicis cortex water extract showed no toxicity toward RAW264.7 macrophages and HaCaT keratinocytes. The Ailanthi radicis cortex water extract promoted the synthesis of procollagen type-1 and collagen type-1 at concentration dependent manner. These results suggested that the water extract from the Ailanthi radicis cortex have anti-aging properties and could be used as a natural source for development of functional cosmetics.
