All things connected to the Internet have to ensure interoperability between each other. Web of Things (WoT) is an Internet of Things (IoT) Web standard technology that enables the communication between smart devices and web-based applications. In order for WoT to be possible, monitoring of all devices connected to the Internet have to be possible. To this end, various efforts are being made to develop network monitoring applications using the latest Web front-end frameworks, not traditional web-based monitoring. This paper examines and describes the possibilities of applying Web front-end frameworks such as React, Angular and Svelte to the development of network monitoring applications for WoT. This paper also describes the pros and cons of two major frameworks, React and Angular, in developing monitoring applications that support the cross-platforms and cross-browsers in WoT environments and examines the applicability of them by developing simple network monitoring applications using React.

Web programming courses are often included in university Computer Science programs as introductory and foundational computer programming courses. However, amateur programmers often have difficulty learning how to integrate HTML, CSS, JavaScript, and various preprocessors or libraries to create websites. Additionally, many web programming mistakes do not produce visible output in the browser. Therefore, in recent years, Front-End Code Playground (FECP) tools that incorporate HTML, CSS, and JavaScript into a single, online web-based application have become popular. These tools allow web coding to happen directly in the browser and provide immediate visual feedback to users. Such immediate visual feedback can be particularly beneficial for amateur coders to learn and practice with. Therefore, this study gathers data on various FECP tools, compares their differences, and provides an analysis of how such tools benefit students. This study concludes with an outline of the application of FECP to web programming courses to enhance the learning experience.

Each company has different business processes. Since it is impossible that an ERP system contains every different business processes, the productivity of customizing and maintenance well-matched for the business process of a company is the key to successful implementation. This ERP UI development tool was developed for better connection to back-end in terms of customizing and maintenance, integration with design, providing various tools for higher productivity, reusability, and standardized user interface so that it enhances the productivity, meets the UI standard, and copes with upcoming changes of business process. In the further study, the study on the service automation and integrated development environment with front-end and back-end providing through the advanced user convenience development for front-end designer and front-end generator would be carried out.

With the introduction to ebXML and web service related standards, enterprises struggle to adapt to the rapidly evolving technology to meet the complex needs of the enterprise customer. The ability to integrate and interoperate individual services within enterprise and with other enterprise's information technology infrastructure using standard-based business processes is an important element of business process management system. For over 25 years EDI has established VAN based solution of exchanging business information in electronic form. However EDI solutions are only accessible to large organizations due to the cost factor. Moreover lack of well accepted B2B business process standards is hindering the success of promoting interoperability between organizations of any size. ebXML work is focused on defining the standard B2B business process context and its runtime semantics in order to remove these hindrances. However ebXML framework does not recommend any particular implementation model to interact with enterprise internal system. This paper propose a end to end business process management architecture by applying ebXML in the front end of the enterprise system and using BPEL to integrate front end services into related services within enterprise.

These days, various clustering technologies have been adopted to construct web sites. High performance hardware switches have good performance, but have disadvantage of high cost for constructing small and middle-sized web sites. Now a days, many sites have been constructed with the LVS (Linux Virtual Server), which is free of charge and has good performance. Having a centralized load balancing with one front-end, the LVS causes a bottleneck when it receives all at once. In the paper, we suggest a way to remove the LVS bottleneck by providing multiple front-ends. In this architecture, all of cluster nodes act as both a front-end and a back-end. When the load of a node receiving requests is not large enough, the node responds to the client directly. When the load of a node is large enough, the node send the request to a node which is selected by a scheduling algorithm. The scheduling algorithm is discussed to balance loads between servers. While single front-end cluster raises the throughput curvedly, the multiple front-end cluster raises the throughput linearly.

This study is about a case of web application development using representative commercial BIM platform-linked APIs from Autodesk and Bentley Systems. The development method was aimed at application development using Autodesk's Forge API and Bentley System's iTwin API. The specific development content was limited to the Model Viewer, Issues, and File Transfer API, and the administrator's site. The first research result is that parts with different internal configurations of commercial platforms were independently modularized and developed, and the common front-end was unified. The second research result is that a web front-end technology, was used to visualize 3D models using the viewer API, and the possibility of additional application expansion was discovered.

The problem of social phenomenon is getting more complicated than past decades, and the simulation engineers need more computation power to solve the problem. Therefore, the needs of the computational resources of the modeling and simulation environment are increasing. In the perspective of the simulation, it is necessary to allocate computational resources flexibly so that the simulation can be performed per the available budget range. As an alternative to the simulation environment to accommodate these requirements, cloud service has emerged as an environment in which computing resources can be used flexibly. This paper proposes a web-based simulation framework which consists of a front-end that reconstructs the simulation model using the web, and a back-end that executes the discrete event simulation. This paper also carried out a case study which shows web-based simulation framework has better overall runtime than standalone simulation framework.

Since web has been used as the front-end of database, many web database connectivity tools have been developed and being developed now. For web developers and educators, it has been a difficult problem to select one tool out of so many alternatives. This paper compares web database connectivity tools available on PC Windows environment in the viewpoint of developers and educators. This comparative analysis focuses on the functions and programming techniques provided by these tools through implementing a simple case study using these software solutions. The performance analysis of these tools was not done in this reason.

An architecture of a Web-based Decision Support system for mathematical analysis is presented. Front-end modules provide web-client GUI environment for mathematical analysis. The networking architecture is built upon client/server system by Java socket and accesses database by JDBC in WWW. Back-end modules provide decision supporting service and data management for mathematical programming analysis. In the back-end any analysis tools, such as mathematical optimizer, simulation package, or statistics package can be used. As an application example for this implementation, optimal facility replacement decision problem is selected. In the implementation the optimal facility replacement decision problem is formulated as a shortest path problem. It uses Oracle DB and CPLEX package as the mathematical optimizer. While ORAWeb is designed and implemented on the optimal facility replacement problem, it can easily be extended to any decision supporting problems that would require mathematical optimization process.
