Structural equation modeling and GIS application into non-carcinogenic health risk assessment of the phreatic aquifers of the south-western coastal basin-Ghana

Introduction: Safety and health risk assessment in industries is associated with uncertainties due to the variables affecting it. Therefore, in this research, optimizing safety and health risk assessment was investigated in construction sites by combining a multi-criteria decision-making technique (TOPSIS) and a fuzzy system. In the present study, to answer this question, a new method was used to optimize health risk assessment in construction workshops. Materials and Methods: The case study was construction sites in Lar, a city in the south of Iran. Based on previous studies and expert opinions, ten criteria were determined to assess safety and health risks in the construction sites. Also, 15 safety and health risks were identified resulting from 12 types of activities in the construction sites. Triangular fuzzy numbers were used for linguistic variables in Fuzzy TOPSIS with R version 1.1 software. Results: Based on the results, the risk of the collapse of adjacent buildings related to the excavation process was the most important safety and health risk in the construction sites with a coefficient value of 0.5. Conclusion: This method can provide desired results with the least uncertainty in prioritizing safety and health risks.

Purpose of this research discuss issues concerning to the purchase of repeated online done consumers/customers to the online. Respondents in this research was the consumers who makes purchase of products online in the areas surrounding the South Tangerang - Jakarta pass judgment in the form of answer a list of questionnaire researchers. Technique the analysis used to answer hypothesis in this research uses Structural Equation Modeling; should be conducted by Software Amos 22.00. Sample of the used as many as 200 respondents who being in the region South Tangerang-Jakarta. The results provide a summary associated with the decision to purchase the online there one variable product innovations have no influence, while two other variables affecting the promotion and trust. Online price relating to the purchase of online birthday there is one variable promotion the price does not affect, while two other variables affect. product innovations and trust.
