The objective of our research is to identify the most significant elements of human risks and to combine them into a single score at the level of teams and departments. Indeed, for companies, what really matters are the stress or dissatisfaction factors that lead to harmful behavior that prevent managers and their teams from achieving their objectives. Based on this research, we are developing a module that will be incorporated into the Oxial software and will also be available as a stand-alone module. This module will collect and analyze the data to calculate a single score measuring the level of human risk. This aspect is very innovative, because no risk management software currently includes a module dedicated to human risks.","PeriodicalId":53248,"journal":{"name":"Informatica economica","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83102346","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}

These are two different items, the first ones are referring to gathering the same medical records for all the patients for every medical field (e.g.: cardiology, dermatology etc.) and the second ones are referring to transport standards like HL7/CDA (Health Level 7/Digital Imaging and Communications in Medicine).

Due to Internet of Things (IoT), cloud computing, smart environment, and virtual machines, the traditional healthcare approaches are replaced by up-to-date (remote) health monitoring systems in smart environments.

These outbreaks continue at an accelerated pace even though efforts are made to improve the detection and mitigation of ransomware.

The biggest challenge for project managers is to meet their goals within the given time limit. Machine learning software can take project management software to a whole new level. The objective of this paper is to show the applicability of using neural network algorithms in software effort estimation for project management. To prove the concept we are using two machine learning algorithms: Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM). To train and test these machine learning algorithms we are using the Desharnais dataset. The dataset consists of 77 sample projects. From our results we have seen that Multilayer Perceptron algorithm has better performance than Long Short-Term Memory, by having a better determination coefficient for software effort estimation. Our success in implementing a machine learning that can estimate the software effort brings real benefits in the field of project management assisted by computer, further enhancing the ability of a manager to organize the tasks within the time limit of the project. Although, we need to take into consideration that we had a limited dataset that we could use so a real advancement would be to implement and test these algorithms using a real life company as a subject of testing.","PeriodicalId":53248,"journal":{"name":"Informatica economica","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79521125","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}

After identifying the keywords specific to the desired domain, a web crawler is developed for evaluating video resources (from the YouTube platform) in terms of relevance for that domain. Once the most relevant video resources are found, they are indexed with the usage of a NER engine applied on their transcripts. In this manner, semantic queries can be used further in order to find exactly the needed information inside these multimedia resources. The crawler will repeat the indexing process daily in order to maintain the repository of semantically indexed videos up to date.

This paper contains a classification for the threats and vulnerabilities for smartphones and tablets and a short one for IoT devices.
