We have developed a Ch Mechanism Toolkit for analysis and design of mechanisms. It was developed using Ch, an embeddable C/C++ interpreter with extensions. The Ch Mechanism Toolkit allows users to write simple programs for solving complicated planar mechanism problems. As an extension to the toolkit, a Web-based system was created for performing mechanism design and analysis through the internet. This paper will discuss the design and implementation of the Ch Mechanism Toolkit as well as its corresponding web-based system. The web-based mechanism system is especially suitable for distance learning. The web-based system for mechanism design and analysis is available on the Web at http://www.softintegration/webservices/mechanism/.

The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.

In this paper, web-based design and manufacturing systems are compared with a commercial CAD/CAM system from the point of usability. The web-based systems included in this study were MIcro Machining System (MIMS) and SmartFab. In the MIMS architecture, a 3D model in STL format was read via a web browser, sent to the web server for toolpath planning, and NC codes were generated to be fed back to the designer through the web connection. In the SmartFab system, SolidWorks was used as the design interface with provided modified menus for micro machining. These additional menus were created by SolidWorks API that also provided web-based links to the toolpath planner. In the commercial CAD/CAM case, without using any web connection, SolidWorks or CATIA was used for design, and PowerMill was used as a CAM tool. For each design and manufacturing system, accessibility, user-friendliness, toolpath-reliability, and processing time were compared. Total 91 students tested these systems in undergraduate CAD class, and the feedback showed better performance of the web-based system in accessibility, user-friendliness, and processing time. However, reliability of the web-based system showed necessity of further improvement.

Актуальность исследования заключается в анализе роли интерактивных методов, а именно, дистанционного обучения в преподавании хирургических дисциплин в медицинском вузе в условиях пандемии коронавирус. Изучили применение технологий дистанционного обучения при преподавании хирургических дисциплин в условиях пандемии коронавируса. Цель исследования: анализ применения технологий дистанционного обучения при преподавании хирургических дисциплин в условиях пандемии коронавируса. Материалом исследования явились информационные платформы LMS Moodle, Google Meet, модифицированные к on-line обучению рабочая программа дисциплины, учебно методические рекомендации кафедры при изучении хирургических дисциплин on-line, данные опроса студентов относительно восприятия новых методов обучения и их эффективности. Методами исследования были вебинары, видеоконференции, чат, форумы и прочее. Карантинные мероприятия в связи с пандемией COVID-19 заставили образовательные учреждения перейти на дистанционное обучение и стали настоящим вызовом для всего российского образования по его организации. Образовательными ресурсами дистанционного обучения стали дистанционные курсы, виртуальные лабораторные работы, тестовые задания, учебные и методические материалы, веб-ресурсы, терминологические словари. Дистанционное обучение имеет свои преимущества и свои специфические изъяны. Необходимость сохранения непрерывности обучения, обеспечение эффективности усвоения учебной программы обусловило необходимость скорой перестройки методики преподавания, внедрения современных инновационных информационно-коммуникационных технологий. The relevance of the study lies in the analysis of the role of interactive methods, namely, distance learning in teaching surgical disciplines at a medical university in the context of the coronavirus pandemic. We studied the use of distance learning technologies in teaching surgical disciplines in the context of the coronavirus pandemic. The research material was the information platforms Zoom and Microsoft Teams, the work program of the discipline modified for on-line training, educational and methodological recommendations of the department in the study of surgical disciplines on-line, data from a survey of students regarding the perception of new teaching methods and their effectiveness. The research methods were webinars, video conferences, chat and ICQ, forums, etc. Quarantine measures in connection with the COVID-19 pandemic forced educational institutions to switch to distance learning and became a real challenge for the entire Russian education in its organization. Distance learning educational resources have become distance courses, virtual laboratory work, test tasks, educational and methodological materials, web resources, terminological dictionaries. Distance learning has its advantages and its specific flaws. The need to preserve the continuity of learning, ensuring the effectiveness of the assimilation of the curriculum necessitated the rapid restructuring of teaching methods, the introduction of modern innovative information and communication technologies. The purpose of the study: to analyze the use of distance learning technologies in teaching surgical disciplines in the context of the coronavirus pandemic.

Introduction: Implementation of teledermatology in primary care offers the possibility of treating patients using specific dermatologic knowledge in far away places with infrequent availability to these services. It is a priority to implement teledermatology services which demonstrate diagnostic reliability and satisfaction among users. Objectives and methods: To measure the diagnostic reliability of an asynchronous teledermatology web based application by means of intraobserver and interobserver concordance during teleconsultation and traditional presential («face to face») consultation. Furthermore, to evaluate user satisfaction regarding the teleconsultation and the web application.Results: A sample of 82 patients with 172 dermatologic diagnoses was obtained, in which an intraobserver concordance between 80.8% and 86.6%, and an interobserver concordance between 77.3% and 79.6% were found. Satisfaction was evaluated to be on an average of 92.5%.Conclusions: The teleconsultation reliability in teledermatology is evidenced to be high, and is susceptible of improvement through the implementation of health information standards and digital dermatologic photography protocols.


This chapter presents the architecture of Web-based intelligent English instruction system CSIEC (Computer Simulation in Educational Communication) and illustrates its important components with examples: dialogue simulation functions including multiple roles talk show and user participating roles play, vocabulary exercises including crossword, single choice questions and cloze questions, listening, reading comprehension, grammar exercises, reading aloud, individual learner portfolios, collaborative learning, the teacher's management function, feedback, and so on. The system's function of instant feedback to every student and statistical analysis upon all students' responses to question answers characterizes this system as a learner response system. The Web-based system can be browsed not only by the user through traditional personal computers but also through fashionable tablet computers. Besides the Web-based system, a standalone vocabulary learning and assessment system for Windows OS is developed. Its functions are also introduced.

The emergence of the Web and the growth of multimedia technologies offer new mechanisms to support and enhance traditional classroom instruction. This chapter reports on a field study in the use of a Web-based distance learning tool. Students enrolled in traditional classroom courses were provided with asynchronous distance learning support consisting of anytime/anyplace access to classroom lectures via the World Wide Web. The traditional classroom lectures were audio-recorded and the audio transcripts digitized, compressed and stored, along with the synchronized lecture slides, for accessing and viewing via the Web. Usage patterns were unobtrusively monitored and correlated with performance. Additionally, participants’ perceptions were collected, compiled and analyzed. The results showed that repeated use of the Web-based supplement was correlated with better overall performance in the class. They also provided some clues to the motivations of users who seek out and explore collateral Web-based support for their own individual learning. This study provides a foundation for further research and application by: 1) helping to assess the utility of collateral support for traditional instruction using Web-based media, 2) shedding light on user adoption behaviors and attitudes, and 3) identifying practical considerations in the implementation of Web-based support for distance learning.

The main goal of this study is to compare the impact of Web-based information on surface, deep and total learning, on satisfaction and on navigation information of subjects with different study orientations. Three subject groups were selected and each group included only subjects with a specific study orientation: A meaning study orientation, a reproduction study orientation and a disorganized study orientation. After studying a Web-based presentation on ‘Global Warming’, subject's performance was evaluated regarding surface, deep and total learning, satisfaction and navigation style. Results show that, first, subjects with a disorganized study orientation score lower on deep learning and on total learning than subjects with a reproduction study orientation and, second, subjects with a disorganized study orientation felt easier to navigate in the Web-system than subjects with a meaning study orientation (although they visit more pages and spend less time in each one than subjects with a meaning study orientation).
