That's why it emerges the need to develop a risk and vulnerability index. The objective of the investigation is to determine a risk index and vulnerability in function of the sea-coast superficial waters and socioeconomic factors in Isla Colon. The methodology got divided in three parts: determination of a sea Water quality, the threat analysis and vulnerabilities. As a result, it was obtained that the quality of Isla Colon coast zone water is a good quality and it is classified as a threat of anthropogenic type, with respect to flood and landslide threats the threat degree is 2. Analyzing the threats, it can be observed that the physic and environmental ones are in a moderated rank, the educational and the socioeconomic ones are in a low rank. In total the vulnerability is 2.6; therefore, it is obtained that that the risk and vulnerability index is 2.6. In conclusion Isla Colon presents a high vulnerability degree, it is recommended to implement mitigation and awareness measurements to the poblation to avoid that threats be of a higher impact, causing Major disasters and avoiding the resources contamination.","PeriodicalId":388062,"journal":{"name":"2019 7th International Engineering, Sciences and Technology Conference (IESTEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127207354","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}

Supply Chain Agility (SCA) arises as an answer to this problem. The purpose of this article is to review and analyze the latest literature studies about SCA. Furthermore, know the principal drivers and enablers that increase the agility level and the pillars that each company followed to achieve agility. Because of this, it was required to review several specialized author/articles in agility and Supply Chain Management (SCM) concepts, as well as being actualized continuously with the various changes that occur in the areas investigated. For this study, 48 articles were analyzed from different databases, such as Scopus, Emerald Insight, Inderscience, Taylor & Francis, and Science Direct, with a publication range between the years of 2004 and 2018. With this, it is expected that manufacturing companies in Peru or other emerging countries begin to investigate more this strategy, with the aim to become more competitive companies globally.","PeriodicalId":388062,"journal":{"name":"2019 7th International Engineering, Sciences and Technology Conference (IESTEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123845120","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}

In the sample preparation, a solution of tin dichloride SnCl2·2H2O to which was added ammonium fluoride (0.15 wt. NH4F) was used in order to improve its optical and electrical properties. The films were deposited at a temperature of 475°C. A semiautomated deposition equipment allowed controlling the deposition process. The XRD study revealed that the film is polycrystalline in nature with a cassiterite type structure. The existence of microcrystals with an apparent size of 42.54 ± 0.8 nm and residual microtension in the percentage of 0.10323 ± 0.0028 was observed. The morphological study (SEM) revealed a compact and homogeneous substrate coating. The optical transmittance average in the visible region was 81.3%. The use of the Drude-Lorentz model showed that the film thickness and the optical band gap energy are 516 nm and 4.16 eV, respectively. Finally, the thermal characterization suggested that ρ practically does not change, showing a constant value of 1.56 x 10-3 Ω-cm in the temperature range of 0 to 130 ° C.","PeriodicalId":388062,"journal":{"name":"2019 7th International Engineering, Sciences and Technology Conference (IESTEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132419410","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}
