PE-M: Prediction of malnutrition of Barangay 35 Tondo Manila using random forest algorithm

Malnutrition is still an ongoing problem in the Philippines as it poses a threat especially to children. There are multiple considerations for malnutrition in order to help find the root cause of malnutrition for each child, it is quite a tedious task to perform. According to the classification of undernutrition rates, the prevalence in the Philippines is of "extremely high" public health relevance. It was stated that in 2019, the prevalence of underweight and wasting was 19% and 6%, respectively. Poverty amplifies the risk of, and risks from, malnutrition. People who are poor are more likely to be affected by different forms of malnutrition. Also, malnutrition increases health care costs, reduces productivity, and slows economic growth, which can perpetuate a cycle of poverty and ill-health. The application Pe-M, is a web application which is aimed to predict the malnutrition rate within Barangay 35 in Tondo Manila City and also give food recommendations based on the classification the children are categorized. The application uses Random Forest Algorithm in calculating the prediction from the data provided in order to calculate the percentage of malnutrition present in Barangay 35 Tondo Manila City. To ensure that the web application performs as per its specified requirements, a comprehensive specification and evaluation of software product quality was conducted using the ISO 25010 software quality model. This study specifically seeks to evaluate the web application in terms of performance efficiency and usability. The following results show that there are kids that fall in the classification of malnutrition showing that there is malnutrition in the barangay. The confusion matrix shows that RFA gives 87.80% accuracy based on the risk factors given and the trained data in the system. The RFA predicted that 21.95% of the data is said to be the malnutrition rate in the barangay based on the given data and the highest risk factor in the data with 3.6% is mineral water consumption of the citizens. The model identified the risk factors which helped predict malnutrition rate making the model more reliable and transparent.

Implementing a Personalized Integrated Stepped-Care Method (STIP-Method) to Prevent and Treat Neuropsychiatric Symptoms in Persons With Dementia in Nursing Homes: Protocol for a Mixed Methods Study.

BackgroundNeuropsychiatric symptoms occur frequently in many nursing home residents with dementia. Despite the availability of multidisciplinary guidelines, neuropsychiatric symptoms are often inadequately managed. Three proven effective methods for managing neuropsychiatric symptoms were integrated into a single intervention method: the STIP-Method, a personalized integrated stepped-care method to prevent and treat neuropsychiatric symptoms. The STIP-Method comprises 5 phases of clinical reasoning to neuropsychiatric symptoms and 4 stepped-care interventions and is supported with a web application.ObjectiveThis study aims to identify the facilitators and barriers in the implementation of the STIP-Method in nursing homes.MethodsA mixed methods design within a participatory action research was used to implement the STIP-Method in 4 facilities of 2 Dutch nursing home organizations. In total, we aimed at participation of 160-200 persons with dementia and expected an intervention fidelity of 50% or more, based on earlier studies regarding implementation of effective psychosocial interventions to manage neuropsychiatric symptoms. All involved managers and professionals were trained in the principles of the STIP-Method and in using the web application. An advisory board of professionals, managers, and informal caregivers in each facility supported the implementation during 21 months, including an intermission of 6 months due to the COVID-19 pandemic. In these 6-weekly advisory board meetings, 2 researchers stimulated the members to reflect on progress of the implementation by making use of available data from patient records and the web application. Additionally, the 2 researchers invited the members to suggest how to improve the implementation. Data analysis will involve (1) analysis of facilitators and barriers to the implementation derived from verbatim text reports of advisory board meetings to better understand the implementation process; (2) analysis of patient records in accordance with multidisciplinary guidelines to neuropsychiatric symptoms: personalized, interdisciplinary, and proactive management of neuropsychiatric symptoms; (3) evaluation of the web application in terms of usability scores; (4) pre- and postimplementation analysis of patient records and the web application to evaluate the impact of the STIP-Method, such as changes in neuropsychiatric symptoms and informal caregiver burden.ResultsWe enrolled 328 persons with dementia. Data collection started in July 2019 and ended in December 2021. The first version of this manuscript was submitted in October 2021. The first results of data analysis are expected to be published in December 2022 and final results in June 2023.ConclusionsOur study may increase understanding of facilitators and barriers to the prevention and treatment of neuropsychiatric symptoms in nursing home residents with dementia by implementing the integrated STIP-Method. The need for well-designed implementation studies is of importance to provide nursing homes with optimal tools to prevent and treat neuropsychiatric symptoms.International Registered Report Identifier (IRRID)DERR1-10.2196/34550

МАТЕМАТИЧЕСКОЕ МОДЕЛИРОВАНИЕ ПОТОКА ЗАЯВОК К ОБЛАЧНОМУ ВЫЧИСЛИТЕЛЬНОМУ КЛАСТЕРУ

Quality of service parameters estimation becomes even more valuable when using cloud compute services. Mathematical model of described cloud-deployed web application in terms of Processor Sharing (PS) policy for mono-service traffic type proposed in this research. This model has Poisson distribution of the incoming requests flow with intensity ?. Requests awaiting in queue, queue length is considered to be unlimited and all requests should be served. Request in this system is HTTP request with a special payload in JSON format. The size of this payload is different for each request but it lies in a narrow band of values (bytes or decades of bytes). A model of cloud compute cluster was built. Characteristics of relative serving efficiency and relative bandwidth of a single requests flow was calculated using this model for different amount of resource provided for processing of a single request. The dependency of these characteristics from cluster load coefficient is demonstrated in charts. Some conclusions on cloud cluster QoS parameters behavior after the change of input requests flow size. Proposed model helps estimating quality of service parameters and adopting the infrastructure to increased or decreased number of requests from customers and could be used for architecting, deploying and administrating web services.

INTERACTIVE SPATIAL WEB-APPLICATIONS AS NEW MEANS OF SUPPORT FOR URBAN DECISION-MAKING PROCESSES

Abstract. Citizen participation, co-creation – a joint development of professionals and citizens – initiatives for urban planning processes have increased significantly during the last few years. This development has been strongly supported by the evolution of Information and Communication Technologies (ICT). E.g., it has never been easier to get information through your mobile devices wherever and whenever you want it. Public open spatial data is available in many cities around the world and web-based applications use this data to provide tools and services for many different topics such as traffic information, or the communication of health-related information (e.g. ozone, particulate matter or pollen loads). This paper presents typical problems of such web-applications in terms of application design and implementation and usability evaluation via describing three case study applications which have been developed recently. It tries to answer the question: How can this kind of geo-services be developed and used by scientists to enable public participation within data gathering and urban planning processes? All three applications have the common goal to provide interactive geo-visualization and analysis features which are tailored to support users in their urban planning processes. The innovation of those applications lies in their flexibility regarding the topics they can tackle and their capability to perform interactive analyses triggered by the user. The applications have been built with a strong focus on exploring the available data (e.g. Open Government Data – OGD). Two of the applications have been implemented using the R-Shiny framework, the third application, the smarticipate platform, has been developed using ReactJS for the front-end, running a MongoDB in the background which is fed via a micro-service framework. In the latter application, the users can configure topics, i.e. the platform enables the user to create new services for different planning issues.

Search-based Tier Assignment for Optimising Offline Availability in Multi-tier Web Applications

Web programmers are often faced with several challenges in the development process of modern, rich internet applications. Technologies for the different tiers of the application have to be selected: a server-side language, a combination of JavaScript, HTML and CSS for the client, and a database technology. Meeting the expectations of contemporary web applications requires even more effort from the developer: many state of the art libraries must be mastered and glued together. This leads to an impedance mismatch problem between the different technologies and it is up to the programmer to align them manually. Multi-tier or tierless programming is a web programming paradigm that provides one language for the different tiers of the web application, allowing the programmer to focus on the actual program logic instead of the accidental complexity that comes from combining several technologies. While current tierless approaches therefore relieve the burden of having to combine different technologies into one application, the distribution of the code is explicitly tied into the program. Certain distribution decisions have an impact on crosscutting concerns such as information security or offline availability. Moreover, adapting the programs such that the application complies better with these concerns often leads to code tangling, rendering the program more difficult to understand and maintain. We introduce an approach to multi-tier programming where the tierless code is decoupled from the tier specification. The developer implements the web application in terms of slices and an external specification that assigns the slices to tiers. A recommender system completes the picture for those slices that do not have a fixed placement and proposes slice refinements as well. This recommender system tries to optimise the tier specification with respect to one or more crosscutting concerns. This is in contrast with current cutting edge solutions that hide distribution decisions from the programmer. In this paper we show that slices, together with a recommender system, enable the developer to experiment with different placements of slices, until the distribution of the code satisfies the programmer's needs. We present a search-based recommender system that maximises the offline availability of a web application and a concrete implementation of these concepts in the tier-splitting tool Stip.js.

Comparative Analysis of Web Applications using JMeter

The Software testing is done to ensure the quality characteristics of an application like functionality, performance, usability, scalability. Performance testing is a technique for quality assurance. It is a way of testing web applications to guarantee that the applications will perform properly under their expected normal workload. Features and Functionalities supported by a software system is not the sole concern. A software application's performance like its response time, do make a difference. The objective of performance testing is not to discover bugs but to eliminate performance bottlenecks. Performance testing is mainly categorised as Stress and Load testing. JMeter is an Open Source tool, widely used to measure performance parameters of an application. It is a java application for load testing and measuring performance. This paper presents performance testing concepts and a comparative analysis of web applications in terms of its response time, throughput and deviation, proposing a way to increase revenue for web application Industry. Keywords: software testing; web testing; performance testing; Jmeter; load testing; response time

A semantic web enabled approach to reuse functional requirements models in web engineering

Web engineering has emerged as a new software discipline to specifically address the challenges and complexities of developing high quality web applications. A main theme in different web engineering methodologies is to employ model driven development approaches. This increases the level of abstraction and formalism to the extent that machines can better involve in the development process and provide more automation, e.g. automatic code generation from the models. Despite their benefits, a main problem of these model-driven methodologies is that developing each new web application implies creating a probably large number of models from scratch. Hence, model reuse can be considered as the main solution to this problem. In this paper, a semantic web enabled approach is proposed for reusing models, specifically functional requirements models. It takes the brief description of the functional requirements of a new web application in terms of UML use case diagram, and semi-automatically generates the draft of the corresponding detailed description in terms of a set of UML activity diagrams. This is performed by utilizing a repository which contains semantic representation of the models of the previous web applications. The proposed approach is based on novel algorithms for annotating activity diagrams, measuring similarity of use cases, and adapting activity diagrams. The experimental evaluations demonstrate that the proposed approach is promising, and it has good precision and effectiveness.

Programmer Protocol for Identification and Defense of Latest Web Application Security Threats using Open Source Tools

has been an exponential increase in the number of attacks on web applications during the recent years. This paper presents a guideline for programmers to develop robust web applications in terms of security by identification of latest web application security vulnerabilities and devising their control using open source dynamic and static web application security assessment tools. A highly vulnerable web application is taken as a sample and it is projected to dynamic tools which lookup for security loopholes in it according to its behavior in the actual working environment and static tools lookup for security loopholes in the programming logics by static analysis of the actual source code. Finally, the concept of a static analysis monitoring tool is given which can serve a fool proof solution for one of the most encountered attack namely, Cross Site Scripting (XSS).

A Secure Web Application: E-Tracking System

The World Wide Web has experienced remarkable growth in recent years hence security is becoming one of the major promising taskin the present scenario of e-business environment. Web attacks candevastate the system within no time. More than 80% attacks are at application layer and almost 90% applications are vulnerable to these attacks. Traditional solution is not capable to protect the web from such attacks.This paper handles different web attacks and also provide some tricks used by hackers to hack the web world similarly it contains an attempt has been made to analyze impact o f DOS, SQL injection, Cross site scripting, Sniffing/ Request Encoding on web application in terms of throughput and response time etc. It also provides the best protection mechanisms for the said attacks. Our main aim is to analyze both E application one with security (proposed E –Tracking system) and another without security and find the impact of all above attacks on both in terms of request time, response time & throughput etc.

A survey on web modeling approaches for ubiquitous web applications

PurposeUbiquitous web applications (UWA) are a new type of web applications which are accessed in various contexts, i.e. through different devices, by users with various interests, at anytime from anyplace around the globe. For such full‐fledged, complex software systems, a methodologically sound engineering approach in terms of model‐driven engineering (MDE) is crucial. Several modeling approaches have already been proposed that capture the ubiquitous nature of web applications, each of them having different origins, pursuing different goals and providing a pantheon of concepts. This paper aims to give an in‐depth comparison of seven modeling approaches supporting the development of UWAs.Design/methodology/approachThis methodology is conducted by applying a detailed set of evaluation criteria and by demonstrating its applicability on basis of an exemplary tourism web application. In particular, five commonly found ubiquitous scenarios are investigated, thus providing initial insight into the modeling concepts of each approach as well as to facilitate their comparability.FindingsThe results gained indicate that many modeling approaches lack a proper MDE foundation in terms of meta‐models and tool support. The proposed modeling mechanisms for ubiquity are often limited, since they neither cover all relevant context factors in an explicit, self‐contained, and extensible way, nor allow for a wide spectrum of extensible adaptation operations. The provided modeling concepts frequently do not allow dealing with all different parts of a web application in terms of its content, hypertext, and presentation levels as well as their structural and behavioral features. Finally, current modeling approaches do not reflect the crosscutting nature of ubiquity but rather intermingle context and adaptation issues with the core parts of a web application, thus hampering maintainability and extensibility.Originality/valueDifferent from other surveys in the area of modeling web applications, this paper specifically considers modeling concepts for their ubiquitous nature, together with an investigation of available support for MDD in a comprehensive way, using a well‐defined as well as fine‐grained catalogue of more than 30 evaluation criteria.
