Purpose: This study was conducted to develop and test the effects of a coronavirus disease 2019 (COVID-19) education program for nursing students. Methods: This study used a non-equivalent control group pretest-posttest design. A total of 71 undergraduate nursing students who had completed a fundamental nursing course and were in their third or fourth year of university participated in this study (experimental group n=38, control group n=33). The COVID-19 education program was developed according to the stages of analysis, design, development, implementation, and evaluation. The program consisted of three weekly sessions that each lasted about two hours. The data were collected from February 26 to March 26, 2022 and were analyzed using the chi-squared, Fisher's exact, and independent t-tests. Results: Knowledge about COVID-19, knowledge about personal protective equipment and attitudes toward COVID-19 were not significantly different between the experimental and control groups. However, significant differences were found between the experimental and control groups regarding their confidence in COVID-19 patient nursing care (t=3.02, p=.004). Conclusion: It was confirmed that the developed program was effective in enhancing the confidence of nursing students in performing nursing for COVID-19. Therefore, it is proposed that the education program developed in this study be used as part of an infection control education program to improve nursing students' abilities to respond to emerging infectious diseases, including COVID-19.

Objectives : This study aimed to identify the factors that affect the utilization of Korean Medicine within the past year. Methods : I analyzed micro-data from the Korean Medicine Utilization Survey (2020), which surveyed the general public. "User (in last 1 year)" were defined as those who had used Korean Medicine within the past year, while "Non-user (in last 1 year)" were defined as those who had used it in their lifetime but not within the past year. I examined several factors, including general characteristics, perceptions of Korean Medicine, satisfaction with Korean Medicine, and intention for future utilization. I conducted the Rao-Scott chi-squared test and complex sample logistic regression analysis. Results : I analyzed a total of 3,762 respondents, of which 1,442 (36.3%) were User (in last 1 year) and 2,320 (63.7%) were Non-user (in last 1 year). User (in last 1 year) and Non-user (in last 1 year) differed significantly in terms of demographic characteristics, perceptions, and satisfaction with Korean Medicine. Women, the elderly, those with low education levels, non-married individuals, those with low-income, chronic diseases, and poor subjective health conditions were significant factors. Those who used Korean Medicine within the past year were more knowledgeable about Korean Medicine than those who had not used it recently, and recognized herbal medicine as safer. In terms of satisfaction, User (in last 1 year) were more satisfied than Non-user (in last 1 year). The more women, the older, the more aware of Korean Medicine, the safer they perceived herbal medicine, the more satisfied they were with its use, the better their subjective health condition, and the absence of chronic diseases, the less they experienced Korean Medicine. Conclusions : The study showed that positive experiences and perceptions of Korean Medicine increase the likelihood of its utilization. Individuals with better subjective health conditions and without chronic diseases have a lower possibility of using Korean Medicine.

Objective: To determine whether the gonial angle on digital panoramic radiographs is associated with vitamin D receptor (VDR) Taql polymorphism. Methods: Genomic DNA samples were collected from the buccal mucosa of patients aged 26-43 years. TaqMan assay for single nucleotide polymorphism genotyping was used to detect the genotype of Taql polymorphism. The gonial angle was measured bilaterally on panoramic radiography. The normal gonial angle was fixed as 121.8°, and it represented the cutoff value for the high gonial angle (HGA) and low gonial angle (LGA) groups. Various genetic models were analyzed, namely dominant (homozygous [AA] vs. heterozygous [AG] + polymorphic [GG]), recessive (AA + AG vs. GG), and additive (AA + GG vs. AG), using the chi-squared test. Results: The reliability of the gonial angle measurement was analyzed using a random sample (26%) of the tests, with the intra-examiner correlation showing an intra-class correlation coefficient of 0.99. The frequencies of the AA, AG, and GG genotypes of rs731236 polymorphism were 40.5%, 41.9%, and 17.6% in the HGA group and 21.8%, 51.0%, and 27.2% in the LGA group, respectively (P = 0.042). A statistically significant difference was observed in the allele frequencies between the two groups (P = 0.011). Moreover, a significant correlation was observed in the dominant genetic model. Conclusions: Taql polymorphism in the VDR gene plays a critical role in the vertical growth of the mandible and decreased gonial angle.

Purpose: The purpose of this study was to analyze the extent of awareness and understanding of college students on temporomandibular disorder (TMD) and to search for avenues for raising public awareness and improving knowledge about TMD. Methods: One thousand and one hundred and twenty one college students in Gyeonggi-do completed a questionnaire related to awareness, experience and knowledge of TMD and collected data were analyzed by Pearson's chi-squared test. Results: Women were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than men. Third graders were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than any other graders. Third graders the most frequently chose to visit department of dentistry for the treatment of TMD among three graders (p<0.001). Women more frequently chose to visit department of dentistry for the treatment of TMD than men (p<0.001). Health field subjects were more significantly aware of the terms, 'TMD' (p<0.001) and 'jaw joint disease' (p<0.001) than non health field subjects. Having more frequently visited department of dentistry for the treatment of TMD than non health field subjects (p<0.001), health field subjects more frequently chose to visit department of dentistry for the treatment of TMD in the future (p<0.001). Conclusions: The level of awareness and knowledge of TMD was higher in women college students, health field subjects and third graders than men college students, non health field subjects and the rest of two graders, respectively. The higher the level of experience and education of the subject, the more aware the subject was of TMD. Therefore publicity activities and education through various routes are required to raise public awareness and knowledge of TMD. In addition, it is necessary to inform general public of the dentistry specialized for the accurate diagnosis and standardized treatment of TMD.

Edwardsiella tarda is one of the most significant fish pathogens, causes edwardsiellosis in a variety of freshwater fish species, and its antibiotic resistance against multiple drugs has made it a health risk worldwide. In this study, we aimed to investigate the antibiotic resistance (ABR) genes of E. tarda and establish its antibiotic susceptibility. Thus, 540 fish (299 Oreochromis niloticus, 138 O. mossambicus, and 103 O. aureus) were collected randomly from twelve fish farms in three districts of Punjab in Pakistan. E. tarda was recovered from 147 fish showing symptoms of exophthalmia, hemorrhages, skin depigmentation, ascites, and bacteria-filled nodules in enlarged liver and kidney. Antimicrobial susceptibility testing proved chloramphenicol, ciprofloxacin, and streptomycin effective, but amoxicillin, erythromycin, and flumequine ineffective in controlling edwardsiellosis. Maximum occurrence of qnrA, blaTEM, and sul3 genes of E. tarda was detected in 45% in the liver, 58%, and 42% respectively in the intestine; 46.5%, 67.2%, and 55.9% respectively in O. niloticus; 24%, 36%, and 23% respectively in summer with respect to fish organs, species, and season, respectively. Motility, H₂S, indole, methyl red, and glucose tests gave positive results. Overall, E. tarda infected 27.2% of fish, which ultimately caused 7.69% mortality. The Chi-squared test of independence showed a significant difference in the occurrence of ABR genes of E. tarda with respect to sampling sites. In conclusion, the misuse of antibacterial agents has led to the emergence of ABR genes in E. tarda, which in association with high temperatures cause multiple abnormalities in infected fish and ultimately resulting in massive mortality.

Purpose: The purpose of this study was to explore the characteristics of social networks among registered nurses in acute nursing care units. Methods: This study used a survey design. Four nursing units from two acute hospitals were selected using a convenience method, and 83 nurses from those nursing units participated in the study in July 2022. The positive influences among nurses included friendship, collaboration, advice, and referent networks, and the negative influences included avoidance and bullying networks. Using the NetMiner program, the k-means clustering technique was applied to create groups of nodes with similar characteristics. The general characteristics of the participants were analyzed by mean, standard deviation, frequency, and ANOVA or chi-squared test. Results: As a result of dividing the 83 nurse participants into four clusters, positive influencers, silent peers, unwelcome peers, and active bullies were identified. Positive influence group nurses were frequently mentioned in the friendship, collaboration, advice, and referent networks. On the other hand, nurses in the unwelcome group and the active bullying group were frequently mentioned in the avoidance and bullying networks. Conclusion: Social networks that have a positive or negative impact on nursing performance are created through different relationships between nurses. Nurse managers can use the findings to create a more supportive and collaborative environment. Further research is needed to develop intervention programs to improve interactions and relationships between fellow nurses.

Objective: To analyze long-term follow-up sonographic findings of intrathyroidal thymus in children. Materials and Methods: Among 1259 patients with congenital hypothyroidism under 15 years of age who underwent thyroid ultrasonography (US), 41 patients were diagnosed with an intrathyroidal thymus based on US criteria, i.e., hypoechoic solid lesion with punctate and linear echogenicity. In 26 patients aged one to 14 years old, the last follow-up US was performed after 6 to 132 months and compared with the initial US. The lesion was considered to decrease in size if there was a change of more than 2 mm in any dimension. The margin change was divided into well-defined and indistinct, blurred. When the echogenicity changed to a hyperechoic from a characteristic thymic echogenicity pattern, the pattern was considered a hyperechogenic. The changes in size were compared with the changes in shape, margin, and echogenicity pattern. The changes in size, shape, margin, and echogenicity were analyzed the association with the age of last follow-up. Statistical analysis was conducted using the chi-squared test and logistic regression. Results: Fifteen (57.7%) cases were stable in size, and 11 (42.3%) decreased in size, including one that disappeared. Ten (38.5%) cases changed to indistinct margins from initially well-defined margins including one case of initially indistinct margin. Six (23.1%) changed to hyperechogenic, from initially characteristic thymic echogenicity patterns. When follow-up change was compared, decreases in size were significantly associated with lesion changes to indistinct margins (p = 0.004). The age at last follow-up was significantly associated with change to hyperechogenicity (odd ratio, 2.141; 95% confidence interval, 1.144-4.010, p = 0.017). Conclusion: On follow-up US, an intrathyroidal thymus may be decreased in size, with indistinct margins, or show changes to a hyperechoic mass. Decreases in size may be associated with changing to indistinct margins, and changes to hyperechogenicity may be associated with increasing age.

Purpose : This study aimed to determine the mortality rate among elderly patients admitted to the intensive care unit (ICU) for acute drug intoxication resulting from suicide attempts. It also compared the characteristics of survivors and decedents to identify factors associated with mortality. Methods : This retrospective descriptive study included 150 patients aged 65 years or older who were admitted to the ICU of a tertiary university hospital in Gwangju due to acute drug intoxication, with the period spanning January 1, 2018 to December 31, 2020. The collected data were analyzed using descriptive statistics, independent t-tests, Chi-squared tests, Fisher's exact test, and multiple logistic regression analysis. Results : The mortality rate among elderly individuals admitted to the ICU for acute drug intoxication was 19.3%. The likelihood of death was significantly higher in patients with an acute physiology and chronic health examination (APACHE) III score of 70 or above (OR=23.75, 95% CI=3.78-149.46, p<.001) and those with metabolic acidosis on initial acid-base results (OR=3.73, 95% CI=1.12-12.43, p=.032). Conclusion : These findings underscore the need for developing and implementing systematic education and targeted nursing interventions for ICU nurses caring for acutely drug-intoxicated elderly adults, particularly considering the APACHE III score and the presence of metabolic acidosis.

Purpose: Use of dual mobility (DM) articulations can reduce the risk of instability in both primary and revision total hip arthroplasty (THA). Knowledge regarding the impact of this design on patient-reported outcome measures (PROMs) is limited. This study aims to compare clinical outcomes between DM and fixed bearing (FB) prostheses following primary THA. Materials and Methods: All patients who underwent primary THA between 2011-2021 were reviewed retrospectively. Patients were separated into three cohorts: FB vs monoblock-D vs modular-DM. An evaluation of PROMs including HOOS, JR, and FJS-12, as well as discharge-disposition, 90-day readmissions, and revisions rates was performed. Propensity-score matching was performed to limit significant demographic differences, while ANOVA and chi-squared test were used for comparison of outcomes. Results: Of the 15,184 patients identified, 14,652 patients (96.5%) had a FB, 185 patients (1.2%) had a monoblock-DM, and 347 patients (2.3%) had a modular-DM prosthesis. After propensity-score matching, a total of 447 patients were matched comparison. There was no statistical difference in the 90-day readmission (P=0.584), revision rate (P=0.265), and 90-day readmission (P=0.365) and revision rate due to dislocation (P=0.365) between the cohorts. Discharge disposition was also non-significant (P=0.124). There was no statistical difference in FJS-12 scores at 3-months (P=0.820), 1-year (P=0.982), and 2-years (P=0.608) between the groups. Conclusion: DM bearings yield PROMs similar to those of FB implants in patients undergoing primary THA. Although DM implants are utilized more often in patients at higher-risk for instability, we suggest that similar patient satisfaction may be attained while achieving similar dislocation rates.

This study aimed to assess the level of intention to tampon use among female university students and to identify factors influencing intention to tampon use. The participants were 140 female university students. Data collection was performed through an online survey using chi-squared test, spearman's correlation coefficients, and multivariable logistic regression analysis from March 13 to March 30, 2024. In this study, it was found that 63.6% of female university students had an intention to use tampon and factors influencing intention to tampon use were marital status, length of menstruation, and prior experience with tampon use. Specifically, participants who were 'unmarried', 'had menstruation lasting 5 days or shorter', and 'had previous experience with tampon use' demonstrated a higher intention to use tampons. Therefore, it is necessary to continuously monitor the changing patterns of women's menstrual product usage and intention, identify influencing factors, and establish educational and promotional strategies to provide information on the characteristics and usage of menstrual products, enabling women to choose the best products suited to their menstrual needs.
