This study aimed to provide fundamental data that could guide high school students' night eating behavior by investigating habits of their night eating consumption during COVID-19 pandemic (From 2021/5/13 to 5/20). Association between their eating habits and the Nutrition Quotient for Korean Adolescents (NQ-A) were also explored. This study included a total of 604 students, among whom 441 students were identified as night eating consumers. Among all subjects, 30.5% consumed night eating 3~4 times a week, 27.3% consumed 1-2 times a week, and 27.0% did not consume any night eating at all. The high-night eating group had a higher score of total NQ-A than the non-night eating group for both male (p<0.05) and female (p<0.001) students. This was because male students in the high-night eating group reported significantly higher rates of daily dinner consumption compared to non-night eating group. Furthermore, both male (p<0.05) and female (p<0.001) students showed a significant increase in 'Moderation'. 'Diversity' was also significantly increased in female studies (p<0.05) as subcategories of dietary habits according to night eating frequency. These findings highlight the need for practical research to develop nutritional guidelines for night eating that reflect preferences of students while providing adequate nutritional habits.

Purpose: This study evaluated the internal structure (structural validity, internal consistency, and measurement invariance) of the Health-Related Quality of Life Instrument with Eight Items (HINT-8), developed to measure Korean people's health-related quality of life. Methods: A secondary analysis was conducted using data from the Korea National Health and Nutrition Examination Survey, involving 6,167 adults aged over 18 years. The structural validity of the HINT-8 was assessed using exploratory graph analysis and confirmatory factor analysis. Internal consistency and measurement invariance were analyzed using McDonald's omega (ω) and multigroup confirmatory factor analysis, respectively. Results: The HINT-8 had a single dimension and good internal consistency (ω =.804). The one-dimension HINT-8 exhibited matric invariance but not scalar invariance across sociodemographic groups (sex, age, education, and marital status). Further, it exhibited scalar or partial scalar invariance across medical condition groups (hypertension, diabetes, depressive symptoms, and cancer). Conclusion: The study finds that the HINT-8 demonstrated satisfactory structural validity and internal consistency, indicating its suitability for practice and research. However, the HINT-8 scores cannot be compared across different groups regarding sex, age, education, and marital status, as the interpretation varies within each sociodemographic category. Conversely, interpretation of the HINT-8 is consistent for individuals with and without hypertension, diabetes, depressive symptom, and cancer.

Purpose : This descriptive survey investigated the effects of clinical nurses' critical reflection competency, professional pride, and person-centered care practices on patient safety management activities. Methods : The participants were 183 clinical nurses working at a tertiary hospital in South Korea. The questionnaires consisted of the Critical Reflection Competency Scale for Clinical Nurses Professional Pride the Person-Centered Nursing Assessment Tool and Patient Safety Management Activities. The collected data were analyzed using descriptive statistics, t-tests, ANOVA, Tukey's HSD, Pearson's correlation coefficient, and multiple regression using SPSS 29.0. Results : The mean score for patient safety management activities was 4.65±0.34 out of 5. There were significant differences in patient safety management activities according to age (F=3.90, p =.010), education level (t=-2.56, p =.013), total work experience (F=3.87, p =.010), and the number of healthcare accreditation system experiences (F=5.22, p =.006). Patient safety management activities were positively correlated with critical reflection competency (r=.337, p <.001), professional pride (r=.271, p <.001), and person-centered care practices (r=.399, p <.001). The results indicated that person-centered care practices affected patient safety management activities (𝛽=.358, p <.001) with the explanatory power of 22.5%. Conclusion : To improve clinical nurses' patient safety management activities, it is necessary to develop participatory educational programs that can integrate skills and attitudes based on conceptual knowledge of person-centered care. Intervention studies are needed to test the effect of person-centered care on patient safety when applied in clinical practice.

Background: Oral frailty is defined as the functional decline of the oral function due to aging, and it is associated with frailty and chronic disease. Most of the frailty intervention is for adults aged 65 years and older. However, early intervention for preventive disorder is most important. The objective of this study was to identify the age at which oral frailty surpass the "normal" range. Methods: This cross-sectional study included 719 adults (aged 30~89 years) residing in Gangwon province in May 2023. Risk of oral frailty was assessed using criteria from The Korean Academy of Geriatric Dentistry including oral function such as swallowing and mastication, and frailty. Frailty was assessed using the Kihon Checklist. To determine when oral frailty surpass the "normal" status, statistical analysis including chi-squared tests and multiple logistic regression analysis were performed using R (ver. 4.3.1). Results: There were 388 (54.0%) individuals who had a "normal" status risk of oral frailty. The risk of oral frailty was higher in the 50~54 age group compared to the 30~34 age group (odds ratio [OR] 0.50, 95% confidence interval [CI] 0.28~0.91), after adjusting for gender, education, income, occupation, and frailty (OR 0.46, 95% CI 0.22~0.94). This means that from 50~54 years old, regardless of gender, education, income, occupation, or frailty condition, there is a distinction from the "normal" status. Conclusion: We found that intervention for oral frailty is needed starting from age 50 years. This is the stage where early indications of oral frailty become apparent. Early intervention for oral frailty can lead to a decrease in the prevalence of diseases and medical expenditure. Therefore, early intervention in middle-aged adults of oral frailty is necessary to improve the quality of life related to oral health.

The aim of this study was to evaluate the inhibitory effect of nude pack containing black tea water extract (NPBT) on skin wrinkle formation in hairless mice. Skin wrinkles were induced by UVB irradiation to the backs of hairless mice for 5 weeks. And at the same time, NPBT was applied topically. Wrinkle formation, histological changes, expression of matrix metalloproteinase-3 (MMP-3) and protein activities of MMP-2 and MMP-9 were observed or analyzed. Wrinkles for the control group were formed as a pattern of deep furrows and thick crests. Whereas wrinkles for the NPBT treated group were formed as a pattern of shallow furrows and thin crests, and their wrinkle areas were significantly (p<0.001) lower than the control group. Collagen fibers were arranged irregularly and sparse in density and some elastic fibers were degenerated in the control group, while they were almost intact in the NPBT treated group. MMP-3 mRNA expression in the control group was significantly (p<0.001) higher than the normal group, and that of NPBT treated group was significantly (p<0.001) lower than the control group. The NPBT treated group showed remarkably lower protein activities of MMP-2 and MMP-9 than the control group. NPBT could have a considerable inhibitory effect on skin wrinkle formation in hairless mice.

The purpose of this study was to evaluate the effects of education and test information provision on anxiety, discomfort, and satisfaction of patients during double contrast barium enema. The experiments were conducted from October 11, 2010 to November 5, 2010. Among all patients who visited the hospital to receive colon study in the outpatient radiology clinic of one general hospital located in Seoul, a total of 50 patients fit for selection criteria were divided into an experimental group (25) and a control group (25). After providing education and test information to the experimental group, we evaluated patients' levels of anxiety and discomfort, as well as satisfaction. The experimental group and the control group had different anxiety scores: 3.76 versus 6.04 respectively (P<0.05). In addition, the levels of abdominal pain and anal pain in the experimental group were lower than those of the control group (P<0.05). Lastly, the scores of test satisfaction between two groups were 89.6 and 67.4 respectively (P<0.05). Education and test information provision about the colon study decreased the levels of patients' anxiety and discomfort and increased satisfaction level of the test.

This study aimed to assess whether the changes in compliance rates of evaluation criteria after healthcare accreditation among radiologic technologists working at four university hospitals which had acquired healthcare accreditation in Daejeon metropolitan area. In this study, the evaluation criteria of healthcare accreditation were reclassified and reevaluated to three areas which include patient safety, staff safety, and environmental safety. Each area has eight, three, and five questions, respectively. Each compliance rate was quantitatively measured on a scale of 0 to 10 before and after in this study. The result shows that the overall compliance rates were decreased on all areas compared to the time healthcare accreditation was obtained. The compliance rate of hand hygiene was drastically reduced. To maintain the compliance rates, not only individuals but healthcare organizations should simultaneously endeavor. In particular, healthcare organizations should make an effort to provide continuous education opportunity to their workers and supervise the compliance regularly.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. The subjects of this study were 510 employees in 1 University Hospital and 3 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from April 26 to May 7, 2004 through survey questionnaires. The main results of this study were as follows: First, From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In University hospitals, males than females, and those who had senior officer posts in labor union showed higher positive correlation with the attitude of their colleagues. In general hospitals, those who had served in Union for shorter period showed higher commitment in union. Second, When looking into the major influencing factors on the level of commitment in labor union according to their jobs, male administrators showed higher positive correlation in the level of commitment in labor union and the relationship with union. Among nurses, those who had lower education level, those who had higher job satisfaction, those who had higher emotional attachment to their job, those who had better relationship with union and better satisfaction in union showed higher commitment level. In medical technicians, those who had higher emotional attachment to their job showed higher commitment level. To summarize study results, the level of commitment in labor union depends on job satisfaction, managers' attitudes, emotional attachment to their jobs, union satisfaction factors, their colleagues attitudes toward union and thee atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as job satisfaction is important determinant in union commitment, hospital managers should have countermeasures to enhance the job satisfaction level of hospital employees. Moreover, as managerial factors of the principal of hospital influence union commitment directly, the attitudes of hospital managers toward union and transparency of hospital management should be improved.

Background: No studies on male attitudes towards HPV and HPV vaccination have been conducted in Japan, and little is known globally whether attitudes of single fathers differ to those living with a female partner. This exploratory study assessed whether Japanese fathers were likely to have their daughter vaccinated against HPV in a publically funded program and whether any differences existed regarding attitudes and knowledge about HPV according to marital status. Materials and Methods: Subjects were 27 fathers (16 single; 11 married) who took part in a study on HPV vaccine acceptability aimed at primary caregivers of girls aged 11-14 yrs in three Japanese cities between July and December 2010. Results: Knowledge about HPV was extremely poor (mean score out of 13 being $2.74{\pm}3.22$) with only one (3.7%) participant believing he had been infected with HPV and most (81.4%) believing they had no or low future risk. No difference existed regarding knowledge or awareness of HPV according to marital status. Concerning perceived risk for daughters, single fathers were significantly more likely to believe their daughter was at risk for both HPV (87.5% versus 36.4%; p=0.01) and cervical cancer (75.0% versus 27.3%; p=0.02). Acceptability of free HPV vaccination was high at 92% with no difference according to marital status, however single fathers were significantly more likely (p=0.01) to pay when vaccination came at a cost. Concerns specific to single fathers included explaining the sexual nature of HPV and taking a daughter to a gynecologist to be vaccinated. Conclusions: Knowledge about HPV among Japanese fathers is poor, but HPV vaccine acceptability is high and does not differ by marital status. Providing sexual health education in schools that addresses lack of knowledge about HPV as well as information preferences expressed by single fathers, may not only increase HPV vaccine acceptance, but also actively involve men in cervical cancer prevention strategies. However, further large-scale quantitative studies are needed.
