The new era of hyper-communication has led organizations to increasingly adopt communications technologies such as instant messaging (IM) for better connections and improved work efficiency. The ongoing COVID-19 pandemic has exerted further pressure and many organizations increasingly depend on IM tools to manage remote workers. In this new context, negative workplace impacts of IM seem more plausible, because technology use causes technostress. In this paper, we propose a research model to analyze instant messaging usage effects on individual work performance and well-being by the means of relevant techno-stressors. The model was tested on a sample of 372 employees from Romanian organizations that use instant messaging at work. Econometric analysis relies on the Structural Equation Modelling methodology and uses SPSS AMOS. Our findings suggest that the usage of instant messaging significantly influences on perceived techno-complexity, techno-overload and techno-invasion, which in turn influences, to some extent, both individual work performance and well-being. Dividing the sample according to the type of work (teleworking and office work), we compared the results between these two groups and encountered some significant differences.

The paper deals with the analysis of the influences of job satisfaction among Europeans aged 50 + (SHARE-ERIC’s data set-Wave7) filtered on main residences and education before 1989. Besides confirming the leading role of the workplace atmosphere and own efforts recognition (dual-core), it further validates the assumption that education and residence in former communist countries count when analyzing job satisfaction and brings two particular types of models. We used many methods based on data mining and variable selection, ordinal and binary logistic and probit regressions, cross-validations via LASSO and mixed-effects modeling with random effects on countries, average marginal effects, and logistic-based prediction nomograms. We discovered seven common influences that count the most when analyzing job satisfaction in these circumstances. It is about the dual-core above and the ones corresponding to older respondents, the better-educated ones (ISCED2011), those with computer skills, the ones endowed with thoroughness, and the ones having higher values of the CASP index of life quality. Depending on each of the two specific models, we discovered peculiarities related to the role of some economic (GDP and SMC to GDP) and institutional (WGI) indicators. For the ex-communist models, we found significant negative influences for both categories while, for non-communist ones, only the second category matters and has a positive role.

PurposeThe purpose of this article is to highlight the relevance of the factors that influence the satisfaction of e-commerce consumers in Romania and Moldova. The study aims to clearly define the main influence factors, so that the marketing managers of the online stores can adopt scientific well-founded decisions.Design/methodology/approachThe paper opted for a study including a large sample of 399 respondents from two countries. For the analysis of the factors influencing the e-commerce satisfaction, multiple linear regression analysis was implemented, and their differentiation within the two countries was highlighted by multivariate analysis of variance.FindingsThe research conducted and the results obtained show that there is a differentiation of the factors that influence the level of satisfaction of e-commerce users in Romania and Moldova.Research limitations/implicationsThe research is still limited in terms of population studied to only two countries: Romania and Moldova. Although the study is intended to be exhaustive by analyzing no less than 11 factors influencing the satisfaction generated by e-commerce, it is still limited to this group of representative factors. Another limitation has to do with the limited number of demographic variables the authors have included.Practical implicationsBased on the results, the managerial implications for e-commerce companies that want to uniquely address consumers in Romania and Moldova are related to the decisions of marketing and sales managers who must allocate budgets and resources to improve the eight aspects highlighted in the paper. Also, the e-commerce companies should not allocate resources for the implementation of functionalities such as in-app after sales services, the possibility to cancel an order or the live consultant support feature, because these aspects do not influence the satisfaction of e-commerce consumers in Romania and Moldova.Originality/valueThis paper is the first in the scientific literature that implements a comparative study on the influence factors regarding the e-commerce satisfaction in Romania and Moldova. Also, it is important to mention that the present study is an exhaustive one because it includes many influence factors that were analyzed separately in the previous research papers from literature review.

The purpose of this research is to make a synthesis of the literature on the implementation of information and communication technologies (ICT) in the educational environment, taking into account the advantages and disadvantages, benefits and limitations, attempts to overcome the COVID-19 pandemic, as well as the current needs generated by social distancing. Both the educational and technical components necessary to create and maintain Internet platforms for communication and evaluation are taken into account. The fact that new technologies related to artificial intelligence, robotics, cloud computing and blockchain are progressing rapidly makes Romania accelerate its digital transformation process in accordance with the requirements of the European Union. From now on, every person, especially young people, should constantly improve their digital skills throughout their lives. In fact, the progress in the implementation of technologies in education has been insignificant. Young people tend to use the Internet more to socialize and less to educate themselves. Improvement of results in youth education can be achieved only by innovative teaching systems, based on new services, technologies, competencies of teachers that set clear teaching objectives. It was noted that some aspects of this study were presented at the XX International Scientific and Practical Conference «Statistical Methods and Information Technologies for Analysis of Socio-Economic Development», which took place on May 21, 2020 at Leonid Yuzkov Khmelnytsky University of Management and Law.

The purpose of this research is to define the level of significance for various indicators that influence the degree of consumer satisfaction regarding the use of FinTech technologies and services. The most important factors that influence the level of satisfaction when using FinTech services were considered: comfort and ease of use, legal regulations, ease of account opening, mobile payments features, crowdfunding options, international money transfers features, reduced costs associated with transactions, peer-to-peer lending, insurances options, online brokerage, cryptocoins options and exchange options. The study was conducted on a sample of 162 respondents, persons belonging to the Millennials and Generation Z generations. The values of the indicators for different categories of users of FinTech services and different categories of generations can be determined based on the statistical tests performed and the results obtained from the regression analysis. The values of the indicators are the basic elements for determining the regression model that will help the FinTech service vendors to make personalized decisions for each category of users so that the level of customer satisfaction is maximized. The study carried out within the present article is the first of its kind for Romania, because up to this moment in the specialized literature there are no such studies for Eastern Europe. The research we conducted aims to fill the gap existing in the literature and responds to the expectations and needs of stakeholders in the FinTechs’ business area. The results of the article are relevant to both stakeholders and the scientific community that is concerned about the impact of FinTech technologies.

The purpose of this article is to make an exhaustive analysis of the influencing factors for the phenomenon of workaholism in IT. In contemporary economies, workaholism is an increasingly common phenomenon. Companies should evaluate the impact on workers of this trend, and note that knowledge of the factors influencing the decision to overwork can be a competitive advantage when implementing human resources policies. Our approach involved the use of multivariate analysis of variance combined with multiple linear regression analysis. The article analyzes the data from 178 respondents who are employed in the IT sector in Romania, taking into account seven potential factors of influence. The data and econometric analyses were processed in IBM SPSS Software. The results of the multivariate analysis of variance combined with multiple linear regression analysis show a significant relationship between workaholism and influencing factors such as the remunerative component of work, the intrinsic pleasure of working, the sense of responsibility towards family, and the desire to develop during a professional career. In this study, socio-demographic influences were found to have a weak influence on the decision to work excessively.

The “buzz†surrounding cryptocurrencies in online media last year has led to an increased interest in the topic as a possible source for investments. This paper aims to identify the key success factors for an m-learning cryptocurrency application that explains blockchain technology and cryptocurrencies for non-tech savvy people. The research methodology used for this paper applies the experimental method and probative logic. A survey was conducted among 128 participants, the target population being composed of people who have an interest in cryptocurrencies and who are involved in online crypto communities. The results of the study show that the people who invest in cryptocurrencies are usually those who have a high income and who possess other investment methods as well. When it comes to analyzing the mobile applications success factors, the study revealed that there are no significant differences between people who have cryptocurrency investments and those who do not in ranking mobile apps success factors. Also, besides cryptocurrency training the news and prices are among the most important features of an m-learning cryptocurrency application and on that account such an app must include them. The originality of this study comes from addressing an innovative topic as the research in this field is scarce. Furthermore, this paper raises awareness towards the necessity of educating people on this topic, on the need to research before investing in a specific project.

One of the key processes of an open University Information System concerns managing the student exchange activities. In this paper we will try to address the challenges regarding modelling and implementation when integrating such a process by crossing different information systems. Our approach will leverage SOA architecture by using BPM in order to structure and build the service orchestration level.

1 SOA MODELINGAccording to [1] the Service Oriented Architecture (SOA) concept is based on the principle of developing reusable business service and building applications instead of building monolithic applications in silos.SOA has the potential to bridge the gap between business and technology, improve reuse of existing applications and interoperability with new ones. Some authors [2] consider that software services are the building blocks for SOA, and they can be composed to provide a more coarse grained functionality and to automate business processes.A modeling language is an artificial language that can be used to define system, information in the structure defined by the rules of the system. Rules are used to interpret the association of components in the system. There are two types of modeling languages - Graphical Modeling: it used a diagrammatic approach to represent the system. There are symbols and lines that connect the symbols which is used to display the relationship between the systems. Notations are used to define the constraints in the system.- Textual Modeling: it uses the keywords or special characters with parameters to represent certain information in natural language which can be used by computers for processing [3]. Expressions are used to link the relationship among the text.Service Oriented Modeling (SOM) is the first step to model services of SOA. According to the specialists [3], the approach for modeling SOA with the viewpoint from services is required. Various methods for serviceoriented modeling have been proposed to apply SOA in industrial and business environments by many researchers [4]. They can be seen in Table 1 below:Starting from this table we decided, based on the reviewed literature, to pay attention only to specific modeling approaches, which are more common and used today.1.1.SOAMLUML is used for general purpose modeling of SOA and create visual models. The services were modeled as objects and general purpose of the design was made by it. But when the degree of complexity increased it was not that efficient. This is how SoaML (Service oriented architecture Modeling Language) emerged: as a UML profile and meta-model for the modeling and design of services within a service-oriented architecture [3].SoaML was created to support the following features:* Indentifying services and their requirements.* Defining service consumers and providers as well as the service itself.* Specifying message pattern and protocols for the services.* Different Service classification schemes.* Integration and extension with OMG meta-models and BPMN.The Object Management Group (OMG) proposed SoaML in 2009 for representing SOA artifacts using Unified Modeling Language (UML) as a core-modeling standard. Moreover, a meta-model and a UML profile are provided in SoaML for the specification and design of service to SOA (meta-model for modeling the requirement for a service and UML for specifying services) [4].1.2.SOMFService Oriented Modeling Framework (SOMF) is a model driven engineering methodology which focuses on business process, and the IT is part of the lifecycle. It can also be used at standalone designing platform with other modeling languages such as UML, BPMN, or SoaML to enrich the language syntax. It can also set software development priorities during life cycle stages, and enhance the overall implementation view of the system [3].The SOMF offers specialized modeling notation to help model, analysis and identification services that is proposed by Bell. It provides a formal method of service identification at different levels of abstraction including meta-model concept and specific notation [4].1.3.SOMASOMA is a modeling technique for developing and building SOA-based systems proposed by IBM in 2004. SOMA activities focuses include: service identification (discovering candidate service and interaction between them), service specification (making decision for exposing services), and service realization (capturing service realization). …

The rate of profit is one of the most important indicators for the stakeholders and shareholders of the companies in the modern economy. In the present article we clearly identified the relationship between the net profit margin and other three composite financial indicators for the companies that are included in BET Index, the most important index of the Romanian Stock Exchange. We identified the regression model that includes, with a significance level of 95%, the stockholder’s equity, long-term liabilities, provisions, deferred revenues over a year, total liabilities, working capital and current assets. The regression model was validated by using many statistics: Multiple R, R Square, t test, F test and p-values. Finally, we obtained the complete valid regression model regarding the profitability of Romanian Stock Exchange’s companies.

IntroductionThe development of User Interfaces (UI) has been a topic of interest both for academia and industry since the early 1980s. During the time a constant evolution has occurred in the field and such an evolution has been coupled with a continuous effort to develop new methods and strategies to create UIs in effective and efficient ways [3].UIX (User Interface XML) is a set of technologies that constitute a framework for building web applications. The main focus of UIX is the user presentation layer of an application, with additional functionality for managing events and the state of the application flow. UIX is designed to create applications with page-based navigation, such as an online human resources application, rather than full-featured applications requiring advanced interaction, such as an integrated development environment (IDE) [4].An application can interact with UIX in predefined places called decision points, where a decision is made by the operator or a certain action routine is automatically triggered. Execution of an action terminates in a new decision point. The application's structure is provided to UIX in configuration files, which can be ASCII files, databases, or resource files. UIX includes Java class libraries, APIs, XML languages, and other technologies for developing different aspects of web-based applications [5].2Responsive Web Design (RWD)Nowadays, responsive design has become a major trend in web development due to the high diversity of devices used for web browsing. According to [6] applying responsive design to existing web sites implies major reengineering due to the underlying fluid grid process. Likewise, responsive design is limited to desktop-tomobile adaptation.The expression 'responsive web design' has earned popularity in 2010 when the web designer and developer Ethan Marcotte wrote an article on the subject [7]. The same author considers that the goal of RWD consists in making a web page look equally good no matter the screen size of a device. Before the introduction of responsive web design, web designers and developers created most websites by following the principles of pixelperfect web design. Pixel-perfect web design treats a web page like a page from a magazine. In this approach, the mock-up of a web page is first created in Photoshop, and then a developer recreates that design to fit a web browser. The goal of pixel-perfect web design is to make a web page resemble the original mock-up as much as possible. But a web page is not printed on a piece of paper but viewed in a web browser. Unlike paper, a web browser is a dynamic medium. It allows a user to re-size the browser window itself, and users can also change the size of the font as well. And when this happens, web pages created with pixel-perfect web design principles often break. If a web page was optimized for a 1024 x 768 pixel screen size, for example, that web page will look quite wrong in a smaller or bigger screen [8].As the number of mobile devices that have a variety of screen sizes grows, pixel-perfect web design has become problematic. Responsive web design is an attempt to solve this problem with the following three tools [9]:* a flexible, grid-based layout;* flexible images;* media queries.Flexible grids are created by using percentage (a relative unit) instead of pixel (an absolute unit). Media queries make it possible to apply different cascading style sheets (CSS) depending on the media type and the maximum width of the device screen. With cascading style sheets, one can control images and other fixed-width elements so that they stay contained in their container blocks.Responsive web design makes a web page adjust itself in response to the screen size of a device. This means that there is no longer one fixed layout in which the elements of a web page are permanently placed. Instead, as the size of the screen changes, the layout of a web page adjusts itself and rearranges the elements of the page. …

(ProQuest: ... denotes formulae omitted.)1 IntroductionPeople have always had the ability to recognize and distinguish two different faces, while computers have begun to show the same ability not very long ago. According to [1] by the mid-1960s, researchers began the work on the recognition of human faces using the computer.Lately robust facial recognition systems are becoming more useful, being helpful in various fields such as terrorism and crime fighting and different user authentication in real or virtual spaces for better security. But despite the amazing innovations and developments in which all take part, the extent of a person from a photograph by comparing it with other images previously saved in a database it is still problematic and a very complex topic. This is mainly due to the variety of human faces depending on the area and the different conditions in which they can be, such as camera performance, facial expressions, lighting, makeup, glasses and more.Most times, a very simple variation of these conditions affect the accuracy of the systems through which the facial recognition is performed, mainly when using highly populated databases. This is the main cause for facial recognition systems are not yet widely used.Facial recognition is usually used in security systems and can be compared to other biometric techniques such as fingerprint or iris recognition systems [2]. Also, facial and form recognition could help marketers in having a better impact on their clients because the visual aspect is one of the classic three channels: visual, auditory and kinaesthetic [3]. Some facial recognition algorithms identify faces by extracting landmarks or features of an image with the subject's face, which is nothing more than a set of pixels ordered by a particular pattern [4].Each human face has many distinctive landmarks, different deck peaks that make up facial features. Each face has approximately 80 nodal points of which the following are used for facial recognition [5]:* Distance between the eyes;* Width of the nose;* Depth of the eye sockets;* The shape of the cheekbones;* The length of the jaw line.Before the actual process of recognition is necessary to create image galleries. From the perspective of facial recognition, the gallery is a set of models serving as a reference for biometric matching process [6].The following are the stages of facial recognition [7]:1. The image capture is performed using a video or photo camera. The camera that is used to capture the image is more powerful so the recognition will be much more accurate.2. The face detection is usually a fairly complex process because an image has almost always a background or other faces. Thus, the system will try the standardization of the photo so it has the same characteristics as previously stored images in the gallery.3. The extraction of features and the generation of a model is a mathematical representation named biometric reference that will be the recognition substance.4. Comparing the models is the process by which the biometric reference is compared to the other models of familiar faces in the gallery.5. Declaring identity is establishing the kinship between two references, but which is often carried out by the human factor.2 Mathematical Theories and Techniques for Facial RecognitionTo achieve facial recognition there are some complex mathematical, geometry and photometry algorithms that support the processing and calculations that are made on a photo. First algorithms that were used to process facial recognition were based only on geometry, with which we only identified similarities between the main features as the position of the head, eyes, nose or mouth.A Cartesian plan is a plan made by perpendicular lines that are called lines. If we have two points with coordinates A (xA, yA) and B with coordinates (xB, yB) the calculation of the distance between these two points is. …

The recognition of fingerprints has many utilities in the modern society because the fingerprint could be used as a unique id. In this article we present the main domains where the fingerprint recognition can be used, a short evolution of the fingerprint recognition process and the main steps in pre-processing the digital images. Then, we propose a new Android implementation for an application which is integrated with SourceAFIS library. Our application (BioFinger) implements the fingerprint recognition using the camera from mobile devices and we also present the obtained results and future directions.

In contemporary economies, reputation has become a very important factor for companies that interact directly with customers. In this context, food-delivery companies must take into account the risks associated with reputation when making operational or investment decisions. Knowing the factors that influence the perception of reputation becomes a competitive advantage for improving or even eliminating the risks related to these indicators. The aim of the study was to explain the influence level and the contribution of influence factors on the reputation of food-delivery companies in Romania. The research analyzed data from 152 respondents who are food-delivery customers from Romania, considering nine possible influencing factors. The data were analyzed in SPSS and the multivariate linear regression analysis and the multivariate analysis of variance were used. The results showed a significant relationship between the perception of reputation and influencing factors such as the quality of the food delivered, the price of the food-delivery service, the variety of the menu, the taste of the food, the perception of companions, and the quality of the electronic application. Our research only partially confirmed certain socio-demographic influences on the perception of reputation. The limitations of the research are determined by the region related to Romania and by the number of socio-demographic variables.

Food safety is a core concern of the European Union in terms of the related legal provisions and of the importance that is given to it. While the food labeling system is already standardized to a large extent, there are areas that still need improvement. In this article, we will present the existing labeling standards, highlight the issues that these standards are facing, identify the possibilities of improvement for the food labeling system and propose a concrete way of using Information Technology to benefit the ethics of food safety. Starting off from the current technological capabilities and from the need to improve the labeling system, we will integrate the Quick Response code technology into a new software architecture able to resolve some of the issues identified. The software architecture relies on a relational data model and on web services that are integrated into an Android application, so that consumers may benefit from additional useful information when they must make a buying decision concerning food products. Our architectural proposal also involves smart information integration with health insurance systems in order to increase the usefulness of the data displayed on food labels.

During the last years, the evolution of mobile applications allowed the developers to become more and more creative. In this way, we can imagine many applications models with a real impact in the real life. In this article we are trying to present a case study for a monitoring sys-tem using the Android platform and the benefits of computer networks. We use the power of mobile sockets and mobile threads, integrating them in a complex architecture in order to ob-tain a real monitoring system. As an immediate application, we propose a baby monitoring sys-tems so that the children could be remotely supervised by their parents. The case study is based on an Android mobile client-server architecture and also uses the capabilities offered by the phone’s speaker and microphone. We intend to have a robust application and that’s why we in-itially preferred Network Service Discovery and Android P2P, but these functionalities are im-plemented starting with Android 4.1. So, we emulated all these functionalities by using a model based on sockets and server sockets.

The introduction of new materials as Power Point presentations are the most convenient way of teaching a course or to display a scientific paper. In order to support this function, most schools, universities, institutions, are equipped with projectors and computers. For control-ling the presentation of the materials, the persons that are in charge with the presentation use, in most cases, both the keyboard of the computer as well as the mouse for the slides, thing that burdens, in a way, the direct communication (face to face) with the audience. Of course, the invention of the wireless mouse allowed a sort of freedom in controlling from the distance the digital materials. Although there seems to appear a certain impediment: in order to be used, the mouse requires to be placed on a flat surface. This article aims at creating a new application prototype that will manipulate, only through the means of a light-beam in-strument (laser fascicle), both the actions of the mouse as well as some of the elements offered by the keyboard on a certain application or presentation. The light fascicle will be "connect-ed" to a calculus system only through the images that were captured by a simple webcam.Keywords: Surface Emitting Lasers, Technology Management, Software Prototyping, Optical Recognition Software1 IntroductionWe are now in the information and knowledge age and the ways data can be pre-sented are very different [1]. The laser point-ers are usually used to attract the attention on some important aspects within the presenta-tion. They also were incorporated in wireless mice, but using such an instrument offers on-ly a simple navigation control and it cannot be used for some more complex applications. The functional requirements aim at the sim-plification of the interaction between man-machine (computer), especially with the help of a webcam and with the help of a laser de-vice. The application will be installed on any computer that has a webcam. Other than a webcam, the user has to have a laser device (laser pointer, or any other powerful light fascicle). Once launched, the application will "read" through the webcam the images that were captured from a certain location that was previously established (example: at a presentation where it is used a projector).Through the means of some processing algo-rithms on the captured images, the action de-veloped by the movement of the laser point on the board, will be transmitted to the com-puter, more exactly to the mouse. In other words, the application will use only one laser device that will allow the user to control the movement and the actions of the mouse from a far distance.The general operational way can be synthe-sized in the following important steps:* The user is the one that will start the ap-plication and who will initialize the main way, meaning the verification of the ex-istence of a webcam, the installation of the specific drivers of the webcam, read-ing the configuration files;* Starting the webcam will automatic initi-ate the capturing of the images (if this op-tion was marked by the user). At this moment will be launched two wires of execution: after the processing of the im-age by the webcam, a web framed is saved as an image.* The captured frame is submitted to opti-mization algorithms for making more ef-fective the detection process of the laser point.* The Laser Module will instantiate the de-tection process of the light fascicle, which through the means of some algo-rithms will give back and it will graph-ically display the location of the laser fascicle; moreover the mouse of the com-puter will be repositioned at a new coor-dinate.* The Mouse Module is the one that will control the actions developed by the laser point, the actions of the mouse as well as the contextual graphic menu.The application will interact with any other program that is installed on the computer. Some specific gestures could be memorized by the application, in order to use a certain order (for example: if the laser point will move to the right in the upper part of the board (N-E) MicrosoftOffice Outlook will open) as well as the various actions of the mouse: single/double left/right clock, saved settings in a configuration file. …

Information and communication technologies are designed to support and anticipate the continuing changes of the information society, while outlining new economic, social and cultural dimensions. We see the growth of new business models whose aim is to remove traditional barriers and improve the value of goods and services. Information is a strategic resource and its manipulation raises new problems for all entities involved in the process. Information and communication technologies should be a stable support in managing the flow of data and support the integrity, confidentiality and availability. Concepts such as eBusiness, eCommerce, Software as a Service, Cloud Computing and Social Media are based on web technologies consisting of complex languages, protocols and standards, built around client-server architecture. One of the most used technologies in mobile applications are the Web Services defined as an application model supported by any operating system able to provide certain functionalities using Internet technologies to promote interoperability between various appli-cations and platforms. Web services use HTTP, XML, SSL, SMTP and SOAP, because their stability has proven over the years. Their functionalities are highly variable, with Web services applications exchange type, weather, arithmetic or authentication services. In this article we will talk about SOAP and REST architectures for web services in mobile applications and we will also provide some practical examples based on Android platform.

In this article we provide a new vision about the enterprise modelling in the context of Business Process Model and Notation (BPMN) and the university area. Although the flow objects, artefacts, connecting objects and swim lanes are very used in the process of Enterprise Modelling, they have specific roles in the university information systems. The paper will reveal a specific approach of BPMN in the context of university information systems based on a comparative analysis of some representative universities from United States and Central Europe. Our ideas are argued with a practical case study that includes 4 realistic and complex systems: study programs and curriculum, students’ admission, student roadmap, students’ exchange. The future directions of the article are some visions of BPMN orchestration of a SOA-based architecture for Student Record Systems.

The goal of this article is to propose a new technical approach regarding the “e-wallet” concept. Although the “e-wallet” concept has many implementations, we consider that we can improve the present level of knowledge by joining the Near Field Communication technology and the “classic” concepts about money. In order to develop a new architecture, we studied the present level of knowledge in the scientific literature and in the industry and we proposed new elements for e-transfers. Also, we made an experiment and the result consists in a prototype based on the Android platform emulators using the Near Field Communication technology. Our electronic prototype will be able to act as a wallet by using only a mobile smart phone because the proposed architecture embeds concepts like money, cards, payments and receipts in a single secured mobile application.

Mobile devices and applications are becoming increasingly present in everyday life and they represent an important success factor in business. Through this work we aim to provide end users a significant increase in the level of contextual information using the Android platform for mobile appli- cation development. The idea of the ""Where?"" application is based on a collaborative architecture involving actors from the business (pharmacies, banks, restaurants, hospitals, etc.) and the end users as primary beneficiaries of the system. In essence, the user needs a service that will be able to locate the best deal to suit its contextual and temporal and spatial availability of the service provider. The proposed new architecture and the application have the possibility to integrate into a single system the local customer needs and business opportunities, directing the beneficiary to the most appropriate lo- cation, taking into account the custom criteria.

The informative messages represent in every organization a central element for sending data about financial situations, group meetings or special events which will happen in the future. This paper intends to present a model for a global information system based on technologies and infrastructures that already exist in mobile environments. The proposed system has real chances of success in Al. I. Cuza University in order to manage the transmission of the students' grade situations.
