A descriptive-correlational research design was utilized to investigate relationships between the variables. Data was collected through a validated and structured questionnaire. Analysis of demographic profiles revealed the majority of respondents were female, aged 31-40 years with 6-10 years of experience. Over half were married. Most held some master's degree units, had received prior inclusive education training, and reported awareness of policies pertaining to inclusion. Results showed teachers experienced moderate overall stress from factors like workload, time constraints, disruptive student behaviors, and insufficient resources. Stress manifested occasionally as exhaustion, frustration, and feelings of being overwhelmed. Coping strategies included discussing issues with colleagues/family and engaging in relaxing activities, but were generally less utilized. Pearson r revealed a significant yet weak relationship between stressors and coping strategies. However, the relationship between stress impacts and coping strategies was non-significant. This suggests coping did not effectively mitigate detrimental stress effects. Notably, neither relationship was strong, with stressors more consistently linked to coping than impacts. These findings highlight the need for holistic teacher wellness programs in Mandaue City Division, addressing diverse challenges through targeted interventions like improved working conditions, adaptive skill-building, and various types of career-stage support. A multi-factorial approach considering the local context is needed to strengthen the resilience and retention of teachers within inclusive education long-term. The study validated the importance of optimizing teacher mental health and well-being given inclusion demands through a customized management plan. By systematically addressing educator needs, sustainability of quality inclusive services can be supported.\u0000DOI: https://doi.org/10.52783/pst.555","PeriodicalId":20420,"journal":{"name":"Power system technology","volume":"34 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141659246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data was collected through validated surveys of 253 teachers recruited through complete enumeration, assessing demographics, engagement, satisfaction, and retention motivators. Descriptive and inferential statistics were used to analyze relationships between variables. Results showed the majority of respondents were female aged 32-41 years, over half were married with master’s units, and most had 16+ years of teaching experience. Two-thirds received inclusive education training and were aware of policies. Descriptive analysis found work engagement and job satisfaction levels were very high. Retention levels were also very high thanks to good relationships, security, and community acceptance. Statistically significant relationships were observed between work engagement-retention (r=0.436) and job satisfaction-retention (r=0.611). These findings provide empirical support for engagement and satisfaction predicting teacher retention, especially in demanding inclusive environments. A targeted Teacher Satisfaction and Retention Enhancement (TSRE) plan is proposed to directly address variables significantly impacting engagement, satisfaction, and retention based on comprehensive analysis. The TSRE plan recommends tailored initiatives targeting motivational and evaluative constructs, alongside concrete strategies, timelines and intended outcomes to enhance identified determinants of satisfaction and continued employment. By optimizing teacher profiles, job design, learning opportunities, and working conditions, this research aimed to provide Philippine public schools with empirical insights enabling educators to effectively fulfill emerging inclusive responsibilities with quality and resilience against challenges, contributing to stability as education reforms progress nationwide.\u0000DOI: https://doi.org/10.52783/pst.554","PeriodicalId":20420,"journal":{"name":"Power system technology","volume":"8 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141661462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The construction parts of the hypothetical areas are located in the urban area of Tabriz city, Iran. All scenarios were assumed to be in the same area configuration, where buildings are located in 25 plots of 40 m x 40 m. The result shows Investigation the average ratings obtained from microclimatic simulation of the first group of scenarios shows that by keeping FAR constant and changing BSC, one cannot expect a specific sequence of changes in microclimatic parameters in the space around the buildings but in the case of the second scenario group which is presented with constant BSC and variable FAR, there is a significant sequence in the order of the obtained ranks and the change trend in the average parameters. The results show scenario A2 with FAR 1 and BSC 40% with the lowest average value (3.5) of the total of four parameters of simulating the hottest and coldest day has achieved the best result and is introduced as the best scenario.
