A qualitative approach was used in this study. Data collection from the multiple case studies was through observation, interview and document study. data was analyzed through a reduction process by analyzing each individual case then also analyzed across cases in a cross-case analysis. The data was also checked for validity, reliability and objectivity to ascertain the degree of credibility, dependability and conformability.  The cross-case findings show that pesantren after establishment go through phases that involve the initial process of searching for identity to efforts to maintain existence through a formulated support system. Pesantrens have a unique organizational culture in various aspects and parts and are not the same as other organizational cultures. The process of organizing pesantrens indicated dynamism in the organizational process while adapting more formal administrative and procedural approaches that conform with contemporary organization management models. It was also found that the challenges of pesantren are more from internal factors especially relating to resistance to change and development emanating from the mindset of the leadership. The study reveals the spiritual framework of the founders of pesantrens in pioneering, organizing and developing their institutions.  The novelty of this study lies in its comprehensive examination of pesantren starting from the process of organizing, developing and the strategies used during the development process how they exist, obstacles faced up to the strategies they use to develop and maintain their existence.  The changing environment has compelled pesantren continue to improve and move minds to grow initiatives to keep up with the changes. and incorporate conventional elements into the implementation of their education system as they face a dilemma between changing or dying under pressure from the power of change itself.  ","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114169158","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}

To describe the feelings and perceptions of a group of health workers, whom in Ecuador, the government, using the media, romanticized, placing them at the level of heroes without a cape who faced the pandemic in the front line. This article presents testimonies that narrate the experiences of human beings strongly marked by closeness to death, the feeling of loss, powerlessness and guilt, since their effort, work, experience and training were not enough to save the lives of critically ill patients of COVID-19. Health workers were romanticized as heroes but at the same time precarious, they received little bio-security protection, which increased infections and deaths at the level of health personnel. The negative impact of COVID 19 at the psychosocial level and the effects on the mental health of health workers is a poorly studied issue; work should be done to better understand the perceptions of frustration, fear, stress and social stigma than many health workers did. They felt by being potential carriers of the virus and taking it to their close environments.","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139348041","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}

Combined with application of encoder-decoder type of neural network model architecture this allows interpretation of model parameters and intermediate activations by domain experts. We show that predictions better than the trivial last observed value are possible. Therefore, informed investment decisions can be supported by neural network models and the proposed representation and model interpretation.  ","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125063791","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}

Benefit cost analysis is carried out to calculate the amount of benefits and costs required from a project, if BCR ? 1 then the project is considered feasible and vice versa if BCR ? 1 is considered not feasible. And multiple linear regression analysis is used to determine the effect between variables. The results of the BCR calculations all get results ? 1, then there is an influence given by the variables X1, X2, X3 on variable Y.

However, there is a dearth of exploratory endeavors in the study of the relationships between customer experience, brand innovativeness, word of mouth, advertising, corporate social responsibility, and customer-based brand equity in the context of retail banking sector in developing nations. Therefore, the present study aims to examine the roles of customer experience, brand innovativeness, word of mouth, and advertising in customer-based brand equity, and evaluate the moderating effect of corporate social responsibility on the relationships in the Chinese retail banking context. The objectives of the study are to explore the factors affecting customer-based brand equity and assess the moderating effect of corporate social responsibility on the relationships between brand influencing factors and customer-based brand equity. A quantitative survey research method was adopted to achieve the research objectives. A total of 389 samples were employed in the data analysis of the present study. The empirical results show that corporate social responsibility displays significant moderating effect on the influences of brand innovativeness, word of mouth, and advertising on customer-based brand equity. Nevertheless, empirical results showed that the moderating effect of corporate social responsibility on the relationship between customer experience and customer-based brand equity is insignificant. With the R2 value of 79 percent that exhibits satisfactory explanatory power obtained in the model, this study has valuable theoretical and practical implications. Theoretically, the present study develops a theoretical model that incorporates corporate social responsibility as a moderator on the effects of factors influencing customer-based brand equity. Practically, the study acknowledges the important roles of corporate social responsibility in building customer-based brand equity and corporate sustainability.  ","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130221751","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 model used was estimated using panel regression (fixed and random effect techniques), Hausman test favored the fixed effect results. The results indicated that the number of ATM machines affects the bank’s performance negatively. This suggests that the higher the number of ATM machines, the lower the performance, since the higher cost related to the usage of such machines with no charge of usage.

Conventional treatments, like sodium stibogluconate, have limitations such as toxicity and drug resistance. Plant extracts, owing to their diverse bioactive constituents, present a potential alternative for disease management.Argemone ochroleuca plant extracts were prepared using ethanol, methanol, and distilled water as solvents. The inhibitory effect on promastigote viability was assessed using a time-based approach, measuring the duration in seconds that is required for inhibition to occur. Interestingly, at certain concentrations, the extract exhibited comparable or even superior efficacy to sodium stibogluconate. Results were compared with the inhibitory effect of sodium stibogluconate. The findings demonstrate the following inhibitory times for Argemone ochroleuca plant extracts: Ethanol: Inhibition occurred at 400 mg/ml in 9 seconds, at 200 mg/ml in 26 seconds, at 100 mg/ml in 60 seconds, and at 50 mg/ml in 128 seconds, Methanol: Inhibition occurred at 400 mg/ml in 13 seconds, at 200 mg/ml in 39 seconds, at 100 mg/ml in 91 seconds, and at 50 mg/ml in 210 seconds and Aquatic extract: Inhibition occurred at 400 mg/ml in 94 seconds, at 200 mg/ml in 150 seconds, at 100 mg/ml in 258 seconds, and at 50 mg/ml in 474 seconds. Comparatively, sodium stibogluconate showed its inhibitory effect at a specific concentration 100 mg/ml in 10 second.These results indicate that the Argemone ochroleuca leaves plant extracts, particularly those prepared using ethanol and methanol, exhibit substantial inhibitory effects on the viability of cutaneous leishmaniasis promastigotes. The variations in inhibitory times among the solvents suggest differences in the bioactive compound extraction and interactions. Ethanol and methanol extracts present potential alternatives to conventional treatments, with faster and efficient inhibitory action.Further research is warranted to elucidate the specific bioactive compounds responsible for these inhibitory effects and to explore the underlying.","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"112 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139348513","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}
