Android-based Information System for Domestic Violence Complaints at P2TP2A Institution in Boalemo Regency

The Integrated Service Center for Women and Children Empowerment (P2TP2A) in Boalemo Regency is an institution that provides services to the community in cases of Domestic Violence (KDRT). The issue that arises is the lack of public knowledge about KDRT and its handling. It is important to continuously educate the community about the negative consequences of domestic violence and the importance of supporting victims and preventing such violence. With increased awareness and community participation, it is hoped that domestic violence can be minimized and eliminated, creating a safe and harmonious environment for all family members. Cases of KDRT continue to occur without being realized by the community and are rarely reported to the Center for Domestic Violence Services (PLKB) due to a lack of information on how to report KDRT cases to the PLKB. Most people feel that the complaint service is limited to reporting without any follow-up process. The research objective is to design an information system that provides information about KDRT as a means of socialization to the community and assists the community in reporting KDRT cases easily and flexibly through Android smartphones. The system analysis method used in this research is the Research and Development (R&D) method, which aims to produce a specific product and test its effectiveness. This application is developed using Java and PHP programming languages, with MySQL as the database for data storage. The system utilizes web service techniques to retrieve data from the server. The result of this research is an application of an information system that facilitates the presentation of information about KDRT through Android smartphones, equipped with online reporting features, and can map the location of the reporter to facilitate follow-up actions by the PLKB. The calculation results show that the Cyclomatic Complexity (CC) = 2 and V (G) = 2, indicating that the system is effective and efficient. The system implementation can be done on Android version 10.0 (Q), version 9.0 (Pie), and version 8.0 (Oreo).

RETRACTED ARTICLE: Automated query classification based web service similarity technique using machine learning

With the tremendous growth of the internet, services provided through the internet are increasing day by day. For the adaption of web service techniques, several standards like ebXML, SOAP, WSDL, UDDI, and BPEL etc. are proposed and approved by W3C. Most of the web services are operating as a query—response model. User has to submit query according to the standard adapted, and services are supporting natural language queries nowadays. The given inputs are processed by web services server can find few similarities in sentence like nouns. The keyword for nouns is filtered accurately and saved in the list as table for each domain. Same time input query words are stored in the domain. The words stored in the domain is matched with the given input queries, later used to find the similarity between the queries In this paper, an automated technique for finding web service similarity based on query classification proposed. The proposed method adapted machine learning approach called KNN, and the data maintained in a hash indexed storage tables. As a result, the relationships between the input query and stored database have been showed in precision, recall, F1-Score and Support.

A Comprehensive Review on Regression Test Case Prioritization Techniques for Web Services

Test Case Prioritization (TCP) involves the rearrangement of test cases on a prioritized basis for various services. This research work focuses on TCP in web services, as it has been a growing challenge for researchers. Web services continuously evolve and hence require reforming and re-execution of test cases to ensure the accurate working of web services. This study aims to investigate gaps, issues, and existing solutions related to test case prioritization. This study examines research publications within popular selected databases. We perform a meticulous screening of research publications and selected 65 papers through which to answer the proposed research questions. The results show that criteria-based test case prioritization techniques are reported mainly in 41 primary studies. Test case prioritization models, frameworks, and related algorithms are also reported in primary studies. In addition, there are eight issues related to TCP techniques. Among these eight issues, optimization and high effectiveness are most discussed within primary studies. This systematic review has identified that a significant proportion of primary studies are not involved in the use of statistical methods in measuring or comparing the effectiveness of TCP techniques. However, a large number of primary studies use ‘Average Percentage of Faults Detected’ (APFD) or extended APFD metrics to compute the performance of techniques for web services.

Analisis, Perancangan Layanan Terpadu e-Mall multi_mitra teknologi SOA menghadapi PandemiCOVID-19

The progress of the development of information technology, communication and SOA (Service Oriented Architecture) that is very fast making all activities of aspects of human life must follow. Especially creating long distance shopping and transactions, one way to avoid the crowds and chaos of people when conditions (epidemics that are simultaneously contagious everywhere, covering large geographical areas) the COVID-19 pandemic. Among them are business, business, education, and other activities. Constraints developing applications, it is very difficult and expensive and requires a long time due to differences in platforms between applications and limited access to the server for the security of the server itself. SOA can solve this problem, can make existing programs become service oriented. This can be done with programs that have been built in a modular manner so that it is enough to only add web services techniques in them. Then a service interface is created without changing the logic of the program. Thus the testing is sufficient on the interface, while the function / logic in it does not need to be tested again because it does not change. SOA integrates and accelerates Multi-Partner business processes, all of which can improve efficiency in all fields. Based on this fact this research was conducted. The research method begins with a literature study, and documentation of related journals as a reference source for analysis. Then proceed with direct observation, conducting interviews with several Mall partners; store owner, banks, residents / customers in the Mall (the author is not allowed to mention the name of the store owner, customer name, name of the store owner, and the name of the Mall) to get the required data Modeling the system design process of the Unified Modeling Language, Enterprise Architect and tenology used by SOA. The system development method uses Prototype. The end result of this research (study) is expected to be used by related parties in developing remote transactions and other parties interested in SOA .

For achieving this goal, our proposed system integrates: cloud computing technology, web services techniques, multi-agent approach, and simulation model. As a scenario, we've chosen the case of a virtual pharmaceutical wholesaler, and we have formulated the problem for command preparation process. The results show that our proposed system helps the decision maker to estimate the economic, environmental and social costs of a logistic process and to know the impact of a new strategic solution and its cost before retaining it.

Performance improvement techniques for geospatial web services in a cyberinfrastructure environment – A case study with a disaster management portal

High population growth, urbanization, and global climate change drive up the frequency of disasters, affecting the safety of people’s lives and property worldwide. Because of the inherent big-data nature of this disaster-related information, the processes of data exchange and transfer among physically distributed locations are increasingly challenging. This paper presents our proposed efficient network transmission model for interoperating heterogeneous geospatial data in a cyberinfrastructure environment. This transmission model supports multiple data encoding methods, such as GML (Geography Markup Language) and GeoJSON, as well as data compression/decompression techniques, including LZMA and DEFLATE. Our goal is to tackle fundamental performance issues that impact efficient retrieval of remote data. Systematic experiments were conducted to demonstrate the superiority of the proposed transmission model over the traditional OGC Web Feature Service (WFS) transmission model. The experiments also identified the optimized configuration for data encoding and compression techniques in different network environments. To represent a real-world user request scenario, the Amazon EC2 cloud platform was utilized to deploy multiple client nodes for the experiments. A web portal was developed to integrate the real-time geospatial web services reporting with real-time earthquake related information for spatial policy analysis and collaborative decision-making.

The Service Recommendation Method based on Semantic Technology in Ubiquitous Computing

In ubiquitous computing environments, users usually compose several services to achieve their goals. The service composition method of this paper is based on WSUN(Web Services on Universal Networks). WSUN approach supports dynamic service composition which takes account of the dynamic factors of ubiquitous environments. In service composition, an operation of a service should be substituted by another operation when the operation is not available. The substitutable operation should support same functionality of unavailable operation. Moreover, it should be able to communicate with pre operation and post operation. The service composition mechanism of WSUN considers the functional similarity between unavailable operations and substitutable operation, but it does not take account of I/O message structures and parameter types of operations. In order to enhance WSUN service substitution method, we use SAWSDL(Semantic Annotation WSDL for XML Schema), which is Semantic Web Services technique. SAWSDL provides two construct: modelReference and schemaMapping. A modelReference specifies the association between a WSDL or XML Schema component and a concept in some semantic data. Semantic annotations using modelReference help to discover substitutable operations. In addition, a schemaMapping solves the heterogeneity of I/O message structures and parameter types of operations. Consequently, even if the operation, which has same functionality of unavailable operation, has different I/O message structures and parameter types of unavailable operation. In order to recommend the operation has good quality, we define the quality of operation. It is a criteria that user can choose the best operation. In addition, we take a user weight for accommodation of user’s requirements. The recommendation system prioritizes operation through calculating quality of operation based on user weight value. Therefore, operation by operation’s priority recommends users. Our system supports substitutable operation discovery mechanism using Semantic Web Services technique, and substitutable operations list to satisfy user’s requirement recommend in ubiquitous environment. Therefore, user can discover substitutable operation in substitution situation. In addition, substitutable operations to fit user requirement recommend user according to weight value from user.

The Operation Recommendation based on QoS in Service Substitution Environment

In ubiquitous computing environments, users usually compose several services to achieve their goals. The service composition method of this paper is based on WSUN (Web Services on Universal Networks) [7]. It supports dynamic service composition which takes account of the dynamic factors of ubiquitous environments. In service composition, an operation of a service should be substituted by another operation when the existing operation is not available. The substitutable operation should support same functionality of existing operation. Moreover, it should be able to communicate with operation back and forth. The service composition mechanism of WSUN considers the functional similarity between unavailable operations and substitutable operation, but it does not take account of input and output message structures and parameter types of operations. In order to enhance WSUN service substitution method, we use SAWSDL (Semantic Annotation WSDL for XML Schema) [15], which is Semantic Web Services technique. SAWSDL provides two construct: modelReference and schemaMapping. A modelReference specifies the association between a WSDL or XML Schema component and a concept in some semantic data. Semantic annotations using modelReference help to discover substitutable operations. In addition, a schemaMapping solves the heterogeneity of I/O message structures and parameter types of operations. Consequently, even if the operation, which has same functionality of unavailable operation, has different I/O message structures and parameter types of unavailable operation. In order to recommend the operation has good quality, we define the quality of operation. It is a criteria that user can choose the best operation. In addition, we take a user weight for accommodation of user’s requirements. The recommendation system prioritizes operation through calculating quality of operation based on user weight value. Therefore, operation by operation’s priority recommends users. Our system supports substitutable operation discovery mechanism using Semantic Web Services technique, and substitutable operations list to satisfy user’s requirement recommend in ubiquitous environment. Therefore, user can discover substitutable operation in substitution situation. In addition, substitutable operations to fit user requirement recommend user according to weight value from user.

DNA 서열 분석을 위한 클라우드 컴퓨팅 기반 지능형 미들웨어 설계

차세대 유전체 해독 기술과 자동화 기술이 발전하면서 DNA 서열 분석 환경이 개선되고 있지만, 아직까지 제한된 컴퓨팅 리소스는 분석시간 단축의 장애요인으로 작용하고 있다. 대부분의 과학 워크플로우 시스템은 수 많은 기능들이 특정 시스템 환경에 맞추어 구현되어 있기 때문에 복잡하고 유동적이지 못하며, 이로 인해 기존 시스템의 컴포넌트들을 클라우드 환경의 새로운 시스템에 적용하기 어려운 한계를 지니고 있다. 본 연구에서는 대량의 DNA 데이터를 동시적으로 분석할 수 있는 가상 인스턴스 제공이 가능하며 시스템간의 상호 운용성을 개선시키기 위하여 웹 서비스, DBMS, 클라우드 컴퓨팅 기능을 지원하는 DNA 서열 분석용 미들웨어를 개발하였다. 본 연구에서 개발된 지능형 미들웨어는 DBMS를 사용하여 파이프라인 정보를 관리하고, 클라우드 환경에서 경량의 가상 인스턴스를 제공하며, 상호운용성 개선을 위하여 단순 URI와 XML을 기반으로 한 RESTful 웹서비스 기능을 제공한다. The development of NGS technologies, such as scientific workflows, has reduced the time required for decoding DNA sequences. Although the automated technologies change the genome sequence analysis environment, limited computing resources still pose problems for the analysis. Most scientific workflow systems are pre-built platforms and are highly complex because a lot of the functions are implemented into one system platform. It is also difficult to apply components of pre-built systems to a new system in the cloud environment. Cloud computing technologies can be applied to the systems to reduce analysis time and enable simultaneous analysis of massive DNA sequence data. Web service techniques are also introduced for improving the interoperability between DNA sequence analysis systems. The workflow-based middleware, which supports Web services, DBMS, and cloud computing, is proposed in this paper for expecting to reduceanalysis time and aiding lightweight virtual instances. It uses DBMS for managing the pipeline status and supporting the creation of lightweight virtual instances in the cloud environment. Also, the RESTful Web services with simple URI and XML contents are applied for improving the interoperability. The performance test of the system needs to be conducted by comparing results other developed DNA analysis services at the stabilization stage.

Towards Agile Application Integration with M2M Platforms

M2M (Machine-to-Machine) Technology makes it possible to network all kinds of terminal devices and their corresponding enterprise applications. Therefore, several M2M platforms were developed in China in order to collect information from terminal devices dispersed all over the local places through 3G wireless network. However, when enterprise applications try to integrate with M2M platforms, they should be maintained and refactored to adapt the heterogeneous features and properties of M2M platforms. Moreover, syntactical and semantic unification for information sharing among applications and devices are still unsolved because of raw data transmission and the usage of distinguished business vocabularies. In this paper, we propose and develop an M2M Middleware to support agile application integration with M2M platform. This middleware imports the event engine and XML-based syntax to handle the syntactical unification, makes use of Ontology-based semantic mapping to solve the semantic unification and adopts WebService and ETL techniques to sustain multi-pattern interactive approach, in order to agilely make applications integrated with the M2M platform. Now, the M2M Middleware has been applied in the China Telecom M2M platform. The operation results show that applications will cost less time and workload when being integrated with M2M platform.

Function oriented service composition modeling

Formal models for service composition have been proposed with the variation of the requirements of service developers. Some famous models have provided checking and verification techniques and tools for the behavior of service composition. These models generally focus much on the message flow of web services and neglecting the data contained in the exchanged messages among services, which restrict the application range of these models and also the web service techniques. As new kind of services with different protocols and communication methods have appeared, it is needed to model service composition from a new view which is adapted to the new development in service area. In this paper we offer a function oriented model of service composition which treats the composite service as a software system and specify the function of services which can be directly used to the realization by service providers.

A Reliable User Authentication and Key Agreement Scheme for Web-Based Hospital-Acquired Infection Surveillance Information System

With the rapid development of the Internet, both digitization and electronic orientation are required on various applications in the daily life. For hospital-acquired infection control, a Web-based Hospital-acquired Infection Surveillance System was implemented. Clinical data from different hospitals and systems were collected and analyzed. The hospital-acquired infection screening rules in this system utilized this information to detect different patterns of defined hospital-acquired infection. Moreover, these data were integrated into the user interface of a signal entry point to assist physicians and healthcare providers in making decisions. Based on Service-Oriented Architecture, web-service techniques which were suitable for integrating heterogeneous platforms, protocols, and applications, were used. In summary, this system simplifies the workflow of hospital infection control and improves the healthcare quality. However, it is probable for attackers to intercept the process of data transmission or access to the user interface. To tackle the illegal access and to prevent the information from being stolen during transmission over the insecure Internet, a password-based user authentication scheme is proposed for information integrity.
