		                        			 Purpose:
		                        			This study aimed to evaluate the performance of a clinical ladder system in a tertiary hospital by examining how nurses' clinical competence and perceptions of the system affect organizational commitment.  
		                        		
		                        			Methods:
		                        			The study involved 394 nurses working at a tertiary hospital. Data were collected from May 3 to July 10, 2023, using a self-reported questionnaire. Statistical analyses, including descriptive statistics, independent t-tests, one-way ANOVA, Kruskal-Wallis test, Scheffé post-hoc test, Pearson correlation, and hierarchical regression analysis, were performed using SPSS 27.0.  
		                        		
		                        			Results:
		                        			Nurses who applied for promotion to the CN III level and current CN III nurses reported higher clinical competence, perceptions of the clinical ladder system, and organizational commitment than those who did not and those at lower levels (p<.001). A positive correlation existed among all independent variables.Controlling for general characteristics, the effects of clinical competence and perceptions of the clinical ladder system explained 49% of organizational commitment variance (Adjusted R 2 =.49, F=33.43, p<.001).  
		                        		
		                        			Conclusion
		                        			Greater clinical competence and positive perceptions of the clinical ladder system are likely to enhance organizational commitment, emphasizing its effectiveness in fostering better organizational outcomes.

		                        			The purpose of this study was to explore and assess the experiences of cancer patients and their caregivers who had been admitted to comprehensive nursing care service wards.  
		                        		
		                        			Methods:
		                        			Data were collected from 10 patients and 10 caregivers by in-depth interviews. The data were analyzed using content analysis of Downe-Wamboldt.  
		                        		
		                        			Results:
		                        			Three categories and seven subcategories were extracted. 1) Realizing institutional limitations of comprehensive nursing care service: ‘Wishing for precise operating systems based on patient severity,’ ‘Anticipating active caregiver participation in treatment process,’ ‘Requiring a countermeasure for safety accidents,’ 2) Professional nursing service which provides relief: ‘Patient-centered professional nursing service,’ ‘Inpatient service that provides relief for patients and caregivers,’ 3) Anticipating continuous use of the service: ‘Inpatient service which users are willing to reuse,’ ‘Wishing for expansion and reinforcement of the service.’

		                        			 Objectives:
		                        			Children and adolescents have a high prevalence of dental caries, primarily due to negligent oral care, frequent snack intake, and inadequate attention to oral disease prevention.Therefore, ensuring oral care and preventing dental caries during this period is essential. Economic barriers, particularly in low- and middle-income countries like the Philippines, limit access to dental care, highlighting the need for national oral health programs. 
		                        		
		                        			Methods:
		                        			This study aimed to investigate the oral health status of children in selected areas of the Philippines and to generate basic data for effective oral health promotion programs. We compared the oral health statuses of enrolled and newly enrolled students in schools with school-based dental clinics. 
		                        		
		                        			Results:
		                        			The results indicated that the prevalence of caries and the average number of carious permanent teeth were lower in enrolled students than in new students. 
		                        		
		                        			Conclusions
		                        			This finding suggests that school-based oral healthcare programs effectively improve children’s oral health and that introducing school-based dental clinics and establishing efficient systems are essential for improving oral health in low- and middle-income countries.

		                        			 Objectives:
		                        			This study was conducted to examine the obstacles in the use of healthcare from the perspective of family caregivers based on their experience of mental healthcare services and to identify practical recommendations according to the family’s needs. 
		                        		
		                        			Methods:
		                        			A focus group interview was conducted with 59 family caregivers of patients with mental disorders. They were asked about the first moment when they took the patient to a psychiatric hospital, their feelings, and experiences during the treatment, relapse or readmission, access to healthcare and obstacles. The results were analyzed in a three-step procedure using grounded theory analysis. 
		                        		
		                        			Results:
		                        			The results showed that the social prejudice and stigma toward mental disorders experienced by the family caregivers hindered the initial treatment approach. Discrimination and disadvantages in healthcare, and poor access to community mental healthcare services, lowered the reliability of institutions and services. A decrease in the sense of healing due to distrust in the treatment and disruption of family life can lead to a vicious circle that affects the continuity of treatment and could result in issues such as the stopping of treatment or difficulty in accessing treatment in case of relapse. 
		                        		
		                        			Conclusion
		                        			Based on these results, policy tasks were proposed to improve accessibility to mental health services according to the needs of the patient’s family.

		                        			 Background:
		                        			Bladder cancer is characterized by frequent mutations, which provide potential therapeutic targets for most patients. The effectiveness of emerging personalized therapies depends on an accurate molecular diagnosis, for which the accurate estimation of the neoplastic cell percentage (NCP) is a crucial initial step. However, the established method for determining the NCP, manual counting by a pathologist, is time-consuming and not easily executable.  
		                        		
		                        			Methods:
		                        			To address this, artificial intelligence (AI) models were developed to estimate the NCP using nine convolutional neural networks and the scanned images of 39 cases of urinary tract cancer. The performance of the AI models was compared to that of six pathologists for 119 cases in the validation cohort. The ground truth value was obtained through multiplexed immunofluorescence. The AI model was then applied to 41 cases in the application cohort that underwent next-generation sequencing testing, and its impact on the copy number variation (CNV) was analyzed.  
		                        		
		                        			Results:
		                        			Each AI model demonstrated high reliability, with intraclass correlation coefficients (ICCs) ranging from 0.82 to 0.88. These values were comparable or better to those of pathologists, whose ICCs ranged from 0.78 to 0.91 in urothelial carcinoma cases, both with and without divergent differentiation/ subtypes. After applying AI-driven NCP, 190 CNV (24.2%) were reclassified with 66 (8.4%) and 78 (9.9%) moved to amplification and loss, respectively, from neutral/minor CNV. The neutral/minor CNV proportion decreased by 6%.  
		                        		
		                        			Conclusions
		                        			These results suggest that AI models could assist human pathologists in repetitive and cumbersome NCP calculations.
