The purpose of the work is to develop a simple solar irradiance prediction model using a deep learning method, the LSTM (long term short term memory). Other than existing prediction models, the proposed one uses only the cloudiness among the information forecasted from the national meterological forecast center. The future cloudiness is generally announced with four categories and for three-hour intervals. In this work, a daily irradiance pattern is used as an input vector to the LSTM together with that cloudiness information. The proposed model showed an error of 5% for learning and 30% for prediction. This level of error has lower influence on the load prediction in typical building cases.

Purpose: This study aims to examine the levels of the perception and work performance of patient safety based on the healthcare accreditation criteria among long-term care hospital nurses. Methods: A cross-sectional study was performed using questionnaires. Out of 205 criteria, 39 items relevant to patient safety were selectively adapted for this study. Data were analyzed with descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Results: The mean scores of perception and work performance were 4.36 and 4.24 out of 5, respectively, and the difference between them was significantly different (t=5.78, p<.001). The two variables were both significantly higher among those nurses who were older, married, head nurses, had many nursing experiences, and aware of Healthcare Accreditation than the other nurses. Positive correlations were observed between perception and work performance in all three sub-systems. The relations between these two in the patient care system was the most highly correlated (r=.894, p<.001). The lowest scores of perception and work performances were fire-related criteria (i.e., reporting). Conclusion: Overall, subject's perception proves to be higher than their work performance. It is necessary to develop some viable environment and training programs to enhance their work performance up to the level of their perception of patient safety.

Purpose: To demonstrate the importance of comprehensive skin observation as an effective intervention for pressure injury prevention in elderly long-term care hospital patients. Methods: The survey was conducted with 70 nursing staff members working at two long-term care hospitals with 200 beds or less in D city. Data were collected from October 16 to October 23, 2019 and analyzed using descriptive statistics, the chi-square test, and the independent t-test with the SPSS 25.0 program. Results: Nursing care knowledge for pressure injury was similar between the two groups. Conversely, nursing care performance for pressure injury degree of the nursing staff in the hospital using skin observation records performed better than those who did not (t=6.11, p<.001). Furthermore, comprehensive skin assessments in long-term care hospitals using skin observation records showed a lower incidence rate of pressure injury than that showed using general skin assessments (t=-5.28, p=.006). Conclusions: Comprehensive skin assessment is important for pressure injury prevention in elderly long-term care hospital patients. To implement this effectively, it is necessary to devise institutional regulations, guidelines, and systematic education programs.

The dye-sensitized solar cells (DSSCs) have achieved so far the highest validated efficiency over 11%. However, the cells with the best performance utilize volatile solvent as a electrolyte, which can cause some practical limitations for the long-term operation. This is one of the most substantial problems to be resolved for the commercialization of DSSCs. In order to improve the long-term stability, many research groups have reported new electrolyte system, to replace the liquid type electrolyte by non-volatile ones. In this work, we studied long-term stability of the DSSCs with various types of electrolytes such as (PVDF HFP) based polymer, eutectic melts of ionic liquids, and liquid based solvent. The cells with various electrolytes have been exposed to the condition under thermal stress and illumination over 1000 hours. We will report the change of photovoltaic properties with time and investigate the degradation mechanism with the impedance spectroscopic analysis.

Objectives: Previous research on turnover has been conducted from the organization's perspective. However, for the long-term retention of dental hygienists, it is necessary to conduct research from an individual's perspective. The purpose of this study is to examine the impact of achievement motivation on the intention to stay of dental hygienists. Methods: This study conducted an online survey targeting dental hygienists working in dental healthcare institutions, using convenience sampling from September, 2023. The analysis included 152 participants with long-term work experience and 121 participants with shorter work experience. Multiple regression analysis was conducted to identify factors influencing retention intentions (PASW Statistics ver. 23.0, p<0.05). Results: Factors influencing intention to stay for long-term dental hygienists included the number of dental hygienists and achievement motivation (responsibility, challenge, task orientation), with a significant impact (adj. R²=0.317). For shorter-term dental hygienists, achievement motivation (challenge, task orientation) demonstrated a significant impact (adj. R²=0.164). Conclusions: It was observed that intrinsic factors, particularly achievement motivation, had a significant impact on intention to stay. Consequently, exploring strategies to satisfy intrinsic motivation, such as achievement motivation, is deemed necessary.

In accordance with the aged society, oral health care for the elderly is considered important to maintain general health. Although the role of dental hygienists is essential for proper health management of the oral cavity, research on the care system for the elderly people's oral health and on the role of dental hygienists in the field of elderly welfare is still insufficient. Hence, the aim of this study is to investigate the status of Korean elderly welfare system and dental hygienists by comparing them with those in Japan, a precedent of aged society. First, we compared and investigated the Japanese long-term insurance system, which provides an institutional basis for a long-term care system for the elderly in Korea. Second, the elderly welfare law and care system, focusing on oral care, were examined. Lastly, in elderly care, we analyzed the distinctions between Korea and Japan regarding dental hygienists' role and scope of work. Taken together, as a precedent of aged society, Japan has shown well-specialized and systematic welfare for the elderly compared with Korea. With the development of the welfare system for the elderly in Japan, the role and the work scope of dental hygienists have been expanded to improve quality of life of elderly people, as a key professional for elderly oral care. Therefore, we should perceive the need for improvement of long-term care insurance and the expansion of dental hygienists' work in Korea. In conclusion, these results could be used as basic data for improving the elderly welfare system and developing dental hygienists in Korea.

Background: Workplace violence (WPV) is becoming an issue that needs immediate attention in the United States, especially during this period as more states are adopting the "stand your ground laws to promote worker protection." This study was conducted to investigate how WPV has contributed to an unsafe environment for nurses and nursing assistants who work in long-term medical care facilities. Methods: A structure questionnaire was used to collect data for the study. Three facilities were sampled and 80 nurses and certified nursing assistants participated in the study. Ninety-two percent (n = 74) were female and 8% (n = 6) were male. Approximately 62% were black or African American, approximately 33% were Caucasians, and only 2% were from other ethnicities. Results: We found that 65% of the participants had experienced WPV while 41% believed that management shows little or no concern for their safety. Approximately 23% of respondents believed that reporting supervisor's WPV act is an unsafe action. In addition, 22% of those who reported that they have experienced WPV believed that the work environment is not safe to perform their duties. This significant difference in perception of workplace safety between those who had experienced WPV and those who had not was significant (t = 3.95, df = 158, p < 0.0001). Conclusion: WPV is an epidemic problem that affects all health-care professionals. The findings of this study could help long-term medical care facilities' management identify the areas to focus on mitigating, controlling, and/or eliminating incidents of WPV.
