A checklist to evaluate adherence to hand hygiene (HH) protocol was implemented. \u0000Results: ATP before HH (510.9/RLU) was reduced after S-HW (54.6/RLU), evidencing a significant decrease (p=0.001). Regarding the bacteria, 26.6/CFU and 4/CFU for EB and E. coli were reported before S-HW, respectively. After S-HW, CFU decreased for EB (21.8/CFU) and E. coli (3.5/CFU) without showing a significant reduction (p=0.679). Low ATP did not evidence a direct relation with EB (p=0.082) and E. coli (p=0.680) reduction. Surgical instrument professionals (p=0.001), general surgeons (p=0.001), residents (p=0.017), orthopedists (p=0.029) and otolaryngologists (p=0.029) evidenced a reduction in ATP after S-HW. Factors such as S-HW direction, surgical soap, moments and time of S-HW implemented showed a statistically significant difference in reduction of ATP, but not in CFU. \u0000Conclusion: Although there was a reduction in elimination of ATP, there was no evidence of a decrease in bacteria. This finding not only allowed to identify potential errors in S-HW processes, but also permitted to generate strategies to improve HH to prevent healthcare-associated infections.","PeriodicalId":41023,"journal":{"name":"Ingenieria Solidaria","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43097347","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}

It will in turn help the organization effectively compete in the ever-challenging global market. \u0000 \u0000Objective: Investigating the relation between job design and burnout in employees (managers) in FMCG companies. It’s done by assessment of changes in core dimensions of burnout with respect to Job Design. \u0000Design/Methodology/Approach: The assessment was done among 350 managers working in FMCG companies in Delhi/NCR. They had been given questionnaires to make assessment of the dimensions of different variables related to burnout. The hypothesis was made that job design and burnout have a negative correlation. Path analysis method was used to generate the model and got tested for job design and burnout. For the analysis of the obtained model SEM software AMOS 20.0 version was used. \u0000Conclusion: Sub hypotheses were formed by transforming the hypothesis. The hypotheses were validated by the results obtained from the analysis. It also substantiated that job design and burnout are negatively correlated significantly. \u0000Originality: The main aspect of this research was to examine the connection amongst these two variables i.e. job design and burnout. The resolve of this research is to examine the significant effect of job design in the alleviation of burnout. The major outcomes of the present research divulge that there is a negative and noteworthy association among job design and burnout. \u0000Restrictions: The correlation has only been validated amongst a limited setup of FMCG managers which gives a conceptual base. It can further be extended to other sectors of public and private companies and to other job roles and services. Various measures of management of employees can further be identified on the basis of this research finding to alleviate burnout.","PeriodicalId":41023,"journal":{"name":"Ingenieria Solidaria","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48264507","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}

Picture Fuzzy Graph (PFG) are applied to solve many complex problems in the real-world problems. The paper has presented a novel approach using deep learning with knowledge graphs to find a human profile including the detection of humans in large data. In the proposed model, digital human profiles are collected from conventional databases combination with social networks in real-time, and a knowledge graph is created to represent complex-relational user attributes of human profile in large datasets. PFG is applied to quantify the degree centrality of nodes. To confirm the proposed model, the proposed model has been tested with data sets through case studies of a forest.

Nowadays there are different research areas in aquaponics, from ones focused on the applied techniques in aquaculture and hydroponic sub-systems; through applied sciences such as modeling from both physical and chemical systems; arriving to the types of aquaponics, qualified from technification grades; concluding with fish and plant crop species and their interaction. In this paper a systematic review is carried out in order to observe the research current state in automated, technified and traditional aquaculture systems, thus having a sight of the investigative orientation in this field. This review is based on scientific papers from four databases, taken in March of 2020, obtaining 1356 results, evaluated and filtered for further analysis. From the review it was found that there is an exponential quantity growth in papers per year, moreover, it is noted that the paper fields of greatest concentration are aquaculture, agriculture, environment, water analysis, horticulture and electronics, the most worked species are lettuce (Lactuca sativa) in hydroponic NFT and tilapia (Oreochromis niloticus) in single recirculating aquaponic systems (SRAPS).
