PURPOSE: The purpose of this study was conducted to identify the impact of Symptom Severity and Symptom Interference on Sleep Disturbance among cancer patients. METHODS: This study was conducted from October 8th to October 25th, 2012. One hundred eight cancer patients were recruited from S city in Korea. The instruments used in this study were the Symptom Severity, Symptom Interference and the Sleep Disturbance scales for patients with cancer. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with the SPSS/WIN 20.0 program. RESULTS: The Sleep Disturbance for cancer patients showed a significant relationship with Symptom Interference and cancer stage. The significant factors influencing Sleep Disturbance were Symptom Severity and Symptom Interference. They explained 40.5% of the variance in stage IV. CONCLUSION: Patients with cancer experienced Symptom Severity and Symptom Interference which led to a negative effect on Sleep Disturbance. The results suggest that intervention programs to reduce Symptom Severity, Symptom Interference could improve Sleep Disturbance for cancer patients.

Purpose: This study investigated the influencing factors of motivation to transfer, job value, and social responsibility on the nursing intention for emerging communicable diseases among nursing students. Methods: Data were collected from January 1-7, 2022 through structured online surveys. The subjects were 140 students in the 3rd or 4th year of nursing college with clinical practice experience. Data were analyzed through descriptive statistics, independent t-test, Pearson's correlation coefficient and multiple regression analysis of hierarchical selection methods analysis using the SPSS statistics program. Results: In the last two-step hierarchical regression analysis, the factors influencing nursing intention for emerging communicable diseases were the attitude of social responsibility (β=.33, p=.001) and intrinsic work value (β=.25, p=.013), with 34% explanatory power of the regression model. Conclusion Results show that the attitude of social responsibility as well as intrinsic work value are key factors that can increase nursing intention for emerging communicable diseases. Thus, it is necessary to expand research on nursing education contents, and to develop programs that strengthen the attitude of social responsibility as well as intrinsic work value.

Purpose: Climate change has various negative effects on human health, which has resulted in increased burden on the health care system. Nurses contribute significantly to assessing climate-related health risks and creating a healthy environment. This study aimed to evaluate the reliability and validity of the Korean version of the Climate, Health, and Nursing Tool (K-CHANT) to measure nurses’ awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Methods: The 22 items of English CHANT were translated into Korean with forward-backward translation techniques. Internal consistency reliability, test-retest reliability, and construct validity using confirmatory factor analysis were performed using SPSS WIN (25.0) and AMOS (26.0). Survey data were collected from 220 master’s, doctoral, and post-doctoral nursing students. Results: The K-CHANT consists of 20 items across 5 domains.Two items of the original CHANT were excluded because of low content validity index and standardized regression weights. The internal consistency reliability of the K-CHANT, assessed by Cronbach’s αá was .81, with an intraclass correlation coefficient of .66~.90. The five subscales model was validated by confirmatory factor analysis (SRMR < .08, RMSEA < .08, AGFI > .70, CFI > .70). Conclusion The K-CHANT has satisfactory construct validity and reliability to measure nurses’ awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Future research should examine nurses’ perceptions and behaviors related to the health effects of climate change and develop an action plan to improve it.

This study was conducted to compare the flexural properties and biocompatibility of experimental 3D printing resins with commercial 3D-printing resins and conventional denture base resin. Auto polymerized pour-type denture base resin (RESS LT; Retec, Germany) was used as a control group. A commercial 3D printing denture base resin, NextDent (Base, Vertex Dental, Soesterberg, Netherlands) and two 3D printing resins, White prototyping resin (PR57-W, Autodesk, USA) and Clear prototyping resin (PR48, Autodes, usa) were compared. Experimental 3D printing resins (E1, E2, E3) were made with different ratios of dimethacrylates. DLP 3D printer (VIDA, Envisiontec) was used for 3D printing. The specimens (64×10×3.3 mm) were made based on the protocol of ISO 20795-1. The flexural strength and flexural modulus were measured by a universal testing machine (Z020, Zwick, Germany) at a crosshead speed of 5 mm/min. MTT test was performed to evaluate the cell viability. The flexural strength and flexural modulus of E2 were significantly higher than those of other groups (p<0.05). Biocompatibility of all experimental 3D printing resins were not significantly different from negative group (p>0.05). E2 is considered to be a promising material as a denture base resin for 3D printing.

Bleeding after endoscopic submucosal dissection (ESD), one of the most common postprocedural adverse events, is the main cause of increased readmission rates and hospital costs. Generally, the incidence of post-ESD bleeding is estimated to be about 5%. However, the incidence of bleeding is particularly increased in high-risk patients. In particular, it has an incidence of over 50% in patients that use antithrombotic agents. The well-known risk factors for post-ESD bleeding include antithrombotic therapy, lesions in the proximal stomach, specimen size >4 cm, and concomitant renal disease. Currently, the number of patients at a high risk of post-ESD bleeding has been increasing. This may be due to the aging society and the increase in the usage of antithrombotic agents. Therefore, several strategies have been employed to prevent post-ESD bleeding. These strategies include acid inhibition therapy, preventive hemostasis using Doppler endoscopic ultrasound and artery-selective clipping, second look endoscopy, the closings method, and the shield methods. However, these methods are technically demanding, which hinders their wide usage in clinical practice. Recently, several hemostatic powders have been developed and clinically used in the treatment of gastrointestinal bleeding. In this article, we review the risk factors for post-ESD bleeding and the recently introduced prevention methods. Moreover, we aimed to explore realistic and appropriate strategies for the prevention of post-ESD bleeding.

The incidence of high-risk pregnancies is increasing in Korea as the birth age increasesdue to late marriage. Maternal-fetal attachment is an important factor that affects children even afterchildbirth, but it is difficult for high-risk pregnant women to form maternal-fetal attachment. Thecurrent study aimed to explore whether taegyo practice (i.e., pregnant women’s efforts for fetal goodgrowth and development), self-esteem, and social support influenced the degree of maternal-fetalattachment in women with high-risk pregnancies.Methods: The participants included 226 pregnant Korean women at ≥20 gestational weeks, hospitalized with 15 high-risk pregnancy conditions as defined by the Ministry of Health and Welfare.Recruitment via convenience sampling was done at four sites in Busan, Korea. Surveys were distributed and collected from February 1 to 28, 2022. Data analysis was conducted using descriptive statistics, the t-test, one-factor analysis of variance, Pearson correlation coefficients, and hierarchicalmultiple regression.Results: On average, participants were 33.97±4.23 years of age and at 31.65±6.23 gestational weeks.Preterm labor (35.4%) and gestational diabetes (21.0%) were the most common high-risk conditions. Maternal-fetal attachment was positively correlated with taegyo practice (r=.70, p<.001),self-esteem (r=.53, p<.001), and social support (r=.53, p<.001), all with statistical significance. Taegyo practice (β=.50, p<.001) and social support (β=.17, p=.030) explained 53% of variance in maternal-fetal attachment in women with high-risk pregnancies.Conclusion: Nurses caring for women with high-risk pregnancies during hospitalization can usethese findings by promoting taegyo practice and enhancing social support to increase maternal-fetalattachment

Objectives: This study aimed to develop and validate machine learning (ML) models using H 2 O-AutoML, an automated ML program, for predicting medication-related osteonecrosis of the jaw (MRONJ) in patients with osteoporosis undergoing tooth extraction or implantation. Patients and Methods: We conducted a retrospective chart review of 340 patients who visited Dankook University Dental Hospital between Janu-ary 2019 and June 2022 who met the following inclusion criteria: female, age ≥55 years, osteoporosis treated with antiresorptive therapy, and recent dental extraction or implantation. We considered medication administration and duration, demographics, and systemic factors (age and medical history). Local factors, such as surgical method, number of operated teeth, and operation area, were also included. Six algorithms were used to generate the MRONJ prediction model. Results: Gradient boosting demonstrated the best diagnostic accuracy, with an area under the receiver operating characteristic curve (AUC) of 0.8283. Validation with the test dataset yielded a stable AUC of 0.7526. Variable importance analysis identified duration of medication as the most important variable, followed by age, number of teeth operated, and operation site. Conclusion ML models can help predict MRONJ occurrence in patients with osteoporosis undergoing tooth extraction or implantation based on questionnaire data acquired at the first visit.

Background: To investigate political participation by dental hygiene students and analyze the differences therein based on the learning efficacy of dental hygiene policy. Methods: A total of 239 dental hygiene students who were expected to graduate responded to the survey. The data were collected online using a structured questionnaire consisting of 6 items on general characteristics, 10 on political participation, and 15 on the learning efficacy of dental hygiene policy. Statistical analysis was performed using SPSS 23.0. Political participation based on the learning efficacy of dental hygiene policy was analyzed using independent t-tests, ANOVA, and multiple regression analysis (p＜ 0.05). Results: Among the dental hygiene students, 60.7% voted in all three recent presidential, general, and local elections, and 14.2% did not. For political parties supported, 65.7% responded that they had “no supporting party,” and 34.3% indicated that they had a “supporting party.” In terms of the level of political participation of dental hygiene students (0∼50 points), the average score was 25.8 points, with the average passive political participation (0∼25 points) score at 15.6 points and the average active political participation (0∼25 points) score at 10.2 points. With an increase in dental hygiene policy learning efficacy, both passive and active political participation showed higher scores (p＜0.05). Conclusion Dental hygiene students showed low political participation. The presence of a supporting party, higher voting participation, and higher learning efficacy of dental hygiene policy were associated with higher passive and active political participation. Therefore, to increase this population’s interest in political participation, various opportunities for related learning need to be promoted and provided in academia, leading to the enhancement of their political capabilities. In this manner, dental hygienists should expand their capabilities in various roles such as advocates, policy makers, and leaders.
