Purpose: The purpose of the present study was to assess the effectiveness of a nursing skills enhancement program in improving the self-efficacy and self-esteem of senior nursing students. Methods: This was a nonequivalent control group pretest-posttest design study that enrolled 306 senior nursing students. The nursing students were randomly assigned to an experimental(n=132) or control group (n=174), and students assigned to the experimental group completed a nursing skills enhancement program, which consisted of four skills training components: IV infusion, enema, $O_2$ therapy by means of cannulation and urinary catheterization. Data were analyzed with frequency, the chi-squared test, and the paired t-test using the SPSS/pc 15.0 statistical program. Results: Our results showed that the self-esteem and self-efficacy of nursing students who were assigned to the nursing skills enhancement program were significantly better compared to those of nursing students in the control group (t=10.198 and t=6.452, for self-efficacy and self-esteem, respectively, p<.001 for both variables). Conclusion: Our findings clearly show that a nursing skills enhancement program is effective in improving the self-efficacy and self-esteem of senior nursing students.

Purpose: This study aimed to identify the level of complete knowledge about hand hygiene indications among nurses working at integrated nursing care service wards. Methods: A total of 127 nurses in eight integrated nursing care service wards completed structured sheets while observing a video based on six scenarios developed by the research team. Complete knowledge level was calculated as the percentage (%) of participants who responded correctly to all questions among participants. Complete knowledge levels according to the scenarios were calculated and compared according to general characteristics using the chi-squared test or Wilcoxon rank-sum test. Results: The complete knowledge level for each scenario ranged from 7.9% (scenario 6) to 42.5% (scenarios 4 and 5), and no one had complete knowledge of all scenarios. Only 3.1% of participants demonstrated complete knowledge in more than four scenarios, and 26.0% had complete knowledge of four or more hand hygiene moments. Complete knowledge level per scenario did not differ depending on work experience at hospitals and study wards, or prior hand hygiene training in the last year. Conclusion: As the complete knowledge level regarding hand hygiene moment is very low, it is suggested that regular hand hygiene training should be provided to nurses using video media that reflect real nursing tasks. Thus, they can acquire complete knowledge of when hand hygiene is needed or not during complex nursing work situations.

Objectives: This study examined the effects of perceived equity in decision-making and gender role attitudes on marital satisfaction among Chinese-Han and Korean-Chinese migrant women. Methods: Data were drawn from the 'National Survey on the Multi-Cultural Families in 2015' and 1,350 Chinese migrant women born after 1979 under the implementation of "one child policy" were selected. Chi-squared test, t-test, and multiple regression analysis were performed for analysis. Results: There were differences between Chinese-Han and Korean-Chinese in marital satisfaction and perceived equity in decision-making. For Chinese-Han, 'balanced group (perceived fairness in decision-making)' showed higher marital satisfaction than 'underbenefited group (husband is more dominant in decision-making)'. For Korean-Chinese, there was no significant difference between the groups. Conclusions: This study found how the perception of equity in decision-making would affect the quality of international marriage relationship. Especially, for Chinese-Han women, the equity plays an important role in marriage relationship.

This study retrospectively analyzed the test results of 441 patients who visited Hospital I in Busan from October 2021 to December 2021 and conducted both mid-term ultrasound and fibroscan tests. The purpose of the study was to investigate the usefulness of fibroscan in inter-fat evaluation by conducting correlation analysis and chi-squared test of inter-fat evaluation using liver ultrasound and fibroscan. As a result of analyzing the correlation between the fatty liver reading result of abdominal ultrasound and Fibroscan UAP, the correlation was found to be r=0.600 and p=0.000. In the inter-provincial evaluation, Fibroscan showed high validity in predicting objective results using inter-provincial values.

Purpose: Nursing students are susceptible to medication safety incidents in the neonatal intensive care unit (NICU) related to a lack of communication experience. The purpose of the present study was to investigate the impact of a NICU medication safety simulation (NMSS) focusing on communication clarity, patient hand-off confidence, and patient safety competency in senior-year nursing students. Methods: The study utilized a nonequivalent control group pretest-posttest design. In total, 60 nursing students were assigned to two groups. The experimental group participated in the NMSS, which included three medication error scenarios. Pairs of students completed the scenarios together in 10 to 20 minutes. Data were analyzed using the chi-squared test, independent t test, and ANCOVA. Results: The experimental group showed significant improvements in communication clarity (p=.015), and patient safety competency (p<.001) compared to the control group. Using the pretest values as covariates, patient hand-off confidence scores significantly increased (p=.027). Conclusion: Implementing the NMSS focusing on communication in the pediatric nursing curriculum helped students to communicate clearly and concisely about medication errors, and its use is recommended to promote patient safety competency in the NICU.

Purpose: This study aimed to examine the health concerns of parents regarding their premature infants and to identify changes in these concerns during perinatal period and after discharge. Methods: This was a retrospective study performed at a single tertiary center that enrolled 119 premature infants who were discharged from the neonatal intensive care unit (NICU) and visited the outpatient pediatrics department between December 2018 and October 2021. Data on the concerns of 176 parents regarding enrolled premature infants' health from before birth to 1 week after NICU discharge were obtained from outpatient records. The t test and with the chi-squared test were used to analyze the data for this study. Results: The consistently greatest focus of parents' health concerns was the respiratory system. The second focus of parents' health concerns before discharge was the central nervous system. However, during the first week after NICU discharge, the gastrointestinal system was the second-most frequent focus of parents' health concerns among parents of infants without diseases related to prematurity and infants with older gestational ages. Conclusion: The results of this study offer insights into the health concerns among parents of premature infants. Parental health concerns about premature infants vary over time, from before birth to post-discharge, necessitating supportive interventions to enhance parental understanding of their child's health status.

Background/Aims: Endoscopic vacuum therapy (EVT) can heal a variety of defects within the gastrointestinal (GI) tract via applying negative pressure, which reduces the defect size, aspirates the infected fluid, and promotes granulation tissue. Here we present our experience with EVT as it relates to both spontaneous and iatrogenic upper GI tract perforations, leaks, and fistulas. Methods: This retrospective study was conducted at four large hospital centers. All patients who underwent EVT between June 2018 and March 2021 were included. Data on multiple variables were collected, including demographics, defect size and location, number and intervals of EVT exchanges, technical success, and hospital length of stay. Student t-test and the chi-squared test were used to analyze the data. Results: Twenty patients underwent EVT. The most common defect cause was spontaneous esophageal perforation (50%). The most common defect location was the distal esophagus (55%). The success rate was 80%. Seven patients were treated with EVT as the primary closure method. The mean number of exchanges was five with a mean interval of 4.3 days between exchanges. The mean length of hospital stay was 55.8 days. Conclusions: EVT is a safe and effective initial management option for esophageal leaks and perforations.

Commonly deep learning methods for enhancing the quality of medical images use unpaired dataset due to the impracticality of acquiring paired dataset through commercial imaging system. In this paper, we propose a supervised learning method to enhance the quality of ultrasound images. The U-net model is designed by incorporating a divide-and-conquer approach that divides and processes an image into four parts to overcome data shortage and shorten the learning time. The proposed model is trained using paired dataset consisting of 828 pairs of low-quality and high-quality images with a resolution of 512x512 pixels obtained by varying the number of channels for the same subject. Out of a total of 828 pairs of images, 684 pairs are used as the training dataset, while the remaining 144 pairs served as the test dataset. In the test results, the average Mean Squared Error (MSE) was reduced from 87.6884 in the low-quality images to 45.5108 in the restored images. Additionally, the average Peak Signal-to-Noise Ratio (PSNR) was improved from 28.7550 to 31.8063, and the average Structural Similarity Index (SSIM) was increased from 0.4755 to 0.8511, demonstrating significant enhancements in image quality.

Objectives The purpose of this study is to investigate the differences between a attention deficit hyperactivity disorder (ADHD) group and a general student group in terms of the perception of the residential environment and periodic activities outside the classroom. Methods The patient group consisted of 62 outpatients or inpatients at the Department of Pediatric Psychiatry, and 49 patients diagnosed with ADHD were selected. For the control group, 3727 youths in elementary schools, middle schools, and high schools of one city were asked to fill out questionnaires. Of the 1717 respondents who responded to the questionnaires, 245 were selected for a patient-controlled study. The differences between the patient group and the control group were compared using the chi-squared test (${\chi}^2$ test). Results There was a significant difference between the patient group and the control group in areas where students responded by "My neighborhood is dirty and littered (p < 0.05)". There was also a significant difference between the patient group and the control group in terms of having more than one club activity per month (p < 0.05). Conclusions It was found that the patients with ADHD are more aware of perceived negative aspects of the area in which they reside, thus reflecting their anxiety. In addition, it was also found that the patient group did not partake in as many social activities as the control group.
