STUDENTS’ PERCEPTIONS ON ENGLISH VOCABULARY TEACHING AND LEARNING BY USING BLOOKET: A CASE STUDY / NHẬN THỨC CỦA SINH VIÊN VỀ VIỆC DẠY VÀ HỌC TỪ VỰNG TIẾNG ANH BẰNG BLOOKET: MỘT NGHIÊN CỨU TÌNH HUỐNG

The use of Information & Communication Technology (ICT) tools to support foreign language teaching and learning has become very common nowadays and makes learning more enjoyable. This study focused on students’ perceptions of using Blooket in teaching and learning English vocabulary. The study case and questionnaires were used to survey (72 non-English major students) and face-to-face interviews (7 students and 3 teachers) to collect data at Long An College of Education (LACE), Vietnam. Data collection was conducted for two months at this site. The data were obtained from the questionnaires sent to students via Google Forms, then analyzed by SPSS software version 26. From the data analysis, the author found that students were very interested in learning vocabulary through http://blooket.com, a classroom game website, which offers a wide variety of interactive and innovative games. The disadvantage is that this site does not allow audio and video to be inserted into the questions and answers; images cannot be inserted into the answer either; and there is a limit of 60 participants if using a free account. Furthermore, with an older version of the phone, you must download the Firefox browser in order to join the game. These disadvantages can all be easily solved. Therefore, it is evident that Blooket is an effective learning medium that helps to increase students' vocabulary when used in online or offline classes by teachers or when learners use it themselves at home to learn vocabulary. Based on data analysis, findings and conclusions were drawn along with some pedagogical advice.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0202/a.php" alt="Hit counter" /></p>

Rancang Bangun Sistem Kontrol Keamanan Gerbang Menggunakan Raspberry Pi B+ Berbasis Web

Computer and information technology from time to time are always experiencing developments, both in terms of hardware, software and the internet being one of the most important things atthis time. The increasing number of applications of computer technology will make the role of computers increasingly important to be more advanced (modernization). The security system isstill not effective and efficient enough, so that a control using a website is needed to help the security control process at the gate. This system is not only used in offices, but can be used inhome security, etc. So we need a security system, where the security control system uses a tool to monitor realtime security via a web browser, namely a webcam (Web Camera). A web-basedgate control system can be designed using the Raspberry Pi B +. From the explanation mentioned above, the researcher made a gate control device that was given to the Microcontroller using a Web Browser in order to open and close the gate. So it is hoped that this security system application can provide a sense of comfort, in addition, of course, with this system application it can reduce the number of crimes that occur both crimes and other crimes.

Using a Framework to Create Better Choices

Intuition can be a good guide for decision making when the current situation generally matches the situations in which the intuition was formed. But for novel or ambiguous situations, relying only on intuition can blind us to possible negative consequences by focusing our attention only on data that support our intuition. To reduce the likelihood of these errors and to better imagine and prepare for the outcomes of our choices, we use a decision-making framework. This note outlines the process of how to apply a framework. Excerpt UVA-E-0407 Jan. 5, 2016 Using a Framework to Create Better Choices Yi Jao, a product manager at an online travel agency, has to decide whether to pursue a potentially lucrative but controversial idea. Recently, an internal team proposed revising the online pricing algorithm to use the cookies from customers' web browsers in order to customize flight and hotel pricing. Because a customer's level of disposable income can be easily inferred from his or her online habits; a travel agency could then use this information to charge from 10% to 30% more for a flight or a hotel. Given the high volatility in flight and hotel prices, it would be almost impossible for customers to trace these price increases back to the booking agency. Jao wants to increase revenue for the company and increase her bonus, but she is also concerned about the fairness of this practice and about violating customer privacy norms. Typically, decision makers in Jao's position feel conflicted and uncomfortable when faced with this type of decision and try to make it as quickly as possible relying only on intuition. Perhaps Jao has competing intuitions and her stronger intuition leads her to pursue the customized pricing algorithm. This decision might have unintended but problematic consequences. For example, perhaps an employee who leaves the company reveals the pricing algorithm to the press, possibly creating a public relations nightmare for the company. Intuition, which comes from our experiences, is a shortcut to making decisions. It can be a good guide for decision making when the current situation generally matches the situations in which the intuition was formed. But for novel or ambiguous situations, relying only on intuition can blind us to possible negative consequences by focusing our attention only on data that support our intuition. . . .

Management Framework for Biosignals in Biomedical Studies: From Study Design to Data Statistics

A centralized and structured management framework for biosignals is proposed. This framework is dedicated to design biomedical studies, acquire and store biosignals and the associated metadata, as well as validate, synchronize, view, and evaluate these signals from an individual study-related perspective. We introduce a five-layer model as the basis of the framework to facilitate data management, which includes the acquisition, validation, postprocessing, and statistics layers, as well as the vertical presentation layer. The strategic interaction between external data (i.e., metadata) and internal data (i.e., recorded biosignals) is defined to favor high-quality results and sustainability of recorded data. For the first time, a systematic software solution was designed to mimic the proposed layer model and to reasonably combine internal and external data management using microservices within a private cloud. Researchers can individually access and manipulate all data using a client implementation or a Web browser in order to address research-related questions, whereas developers can easily implement modular functions and algorithms. A simplified implementation of the proposed framework shows its strong potential in the unification and structuring of biomedical studies as well as in the associated acquisition, storage, and analysis of biosignals.

온도 및 압력 측정에 기반을 둔 디젤 차량의 연료필터 분석 시스템

본 논문에서는 겨울철 저온환경에서 디젤 엔진의 연료필터를 검사하기 위한 온도, 압력 및 유량 분석 시스템을 제안하였다. 디젤엔진의 연료인 경유는 특정 온도 이하로 내려가면 파라핀과 같은 반고체 상태인 왁싱(Waxing)물질을 형성하여 유동성이 낮아지기 때문에 엔진 시동이 원활하지 않다. 그래서 이러한 문제점을 해결하기 위해서 블록 히터를 내장하게 된다. 그리고 연료필터의 성능을 측정하기 위해서는 극저온 하에서 엔진 시동 시부터 온도, 압력 및 유량을 분석할 수 있는 시스템이 요구된다. 본 논문에서는 제작된 시스템을 이용하여 연료필터 주변의 성능에 관계된 물리량을 측정하였으며 이를 분석하였다. 또한 측정된 데이터는 임베디드 시스템의 웹서버를 이용하여 원격 네트워크로 전송하였고 원격에서 사용자들이 웹브라우저를 이용하여 운전 상태를 용이하게 파악할 수 있게 설계하였다. 설계된 시스템을 검증하기 위하여 제작된 소형 실험 챔버에 설치하고 상온 및 극저온 상황에서 실험하여 연료필터 입출력 측 연료의 온도, 압력, 유량 데이터를 얻을 수 있었으며, 연료히터의 동작 시 연료의 흐름이 개선되는 것을 알 수 있었다. In this paper, temperature, pressure and flow analysis system for testing a fuel filter of a diesel engine at the low-temperature environment in winter, is proposed. The light oil of diesel engine below a specific temperature is changed to the waxing materials like paraffin, and it prevents engine to start easily because of reducing fluidity. Thus, built-in block heater should be installed with fuel filter in order to solve this problem. And it is necessary to design evaluation system that can analyze the performance according to temperature, pressure and flow characteristics near fuel filter at a very low temperature. In this paper, we measured a physical quantity related to the performance of around the fuel filter using the proposed system, and analyzed their characteristics. Also the measured data is transferred to remote user by using a web server of embedded systems, and analyzed their conditions in remote place via web browser in order to know the operating status of fuel filter. We installed the proposed system in a small test chamber to verify the performance and took an experiment in normal temperature and very low temperature, and could obtain temperature, pressure and flow of near the fuel filter. As a result, the fuel flow could be improved during operation of the fuel heater.

Virtual Reality Models for the Structural Assessment of Architectural Heritage Buildings

This study shows the advantage of using virtual reality models in the structural assessment of architectural heritage buildings. Today, very powerful numerical methods can obtain the structural behavior of historical buildings, such as discrete and finite element methods. In addition, the continuous improvement of computers has allowed for creating numerical models of entire structures. However, the post-processing and interpretation of the numerical results of these models continue to be a hard task. In this context, virtual reality models are powerful tools to simplify the task of post-processing the numerical results. In this way, the numerical results of a three-dimensional (3D) model, analyzed with any numerical method, can be exported to a virtual reality modeling language (VRML) file format to represent 3D interactive vector graphics, and designed particularly for the World Wide Web system. This property will allow display the virtual model in a tablet computer, notebook or any device with a web browser in order to navigate through the building observing stresses, strains, damages or any result of the numerical model.

Developing an Integrative Evidence Informed Practice Clinical Internship

s EXPLORE September/October 2013, Vol. 9, No. 5 323 Scholars Program a senior faculty member created and implemented an activity to review and evaluate media reports of medical research as an assignment within a year long clinically oriented class. Summary of Work: In 2006 a project was initiated whereby students identified and examined media reports compared with original research studies on which they were based. The project spans three academic terms with graduated series of exercises which elicit growing depth of critical thinking. It was guided by Research Literate Practitioner competencies developed by the grant. Reflection and communication are incorporated into the exercises. A grading rubric based on the competencies was used for assessment. Summary of Results: Based on six cohorts of students, qualitative data indicate that the project had a major impact on students. In written and oral feedback a majority of students report acquiring knowledge of how to use research studies to assess media medical report quality. They also report an increased understanding of research linking to clinical work with patients. A minority of students report not gaining skills from the project due to previous research or ambivalence regarding the import of these skills. Conclusion: Participation in this activity appears to have created an increase in research literacy at the clinical level of interaction with patients. Students can be taught how to analyze media reports of medical studies to determine the accuracy of these reports. This student centered learning activity expands student awareness and practical skills using research in clinical decision making. The practices of self reflection and evidence informed communication with patients are enhanced through this work. Contact: Joseph Coletto, jcoletto@ocom.edu Implementation of a Prospective Clinical Outcomes Study in a CAM/IM Teaching Clinic Ryan Bradley, Brendan Smith, and Erica Oberg 1 Bastyr University, Kenmore, Washington, United States 2 Bastyr University, Edmonds, Washington, United States Background: Over 70% of incoming naturopathic medical students express interest in receiving one-on-one research experiences during their education, however existing research capacity and the availability of research faculty time for mentorship often limit these opportunities. Simultaneously, there is a great need to quantify the outcomes from CAM/IM practices in order to document the effectiveness of these approaches to patients care. Summary of Work: “Naturopathic Patient-Reported Outcomes in Heart Disease and Diabetes (ND-PROHD)” was implemented in January 2012 in order to provide clinical research opportunities for newly created Student Research Clinicians and a Chief Resident within the naturopathic clinical training clinic of Bastyr University. This prospective, observational cohort study uses the Research Electronic Data Capture (REDCap) system coupled with mobile web browsers in order to collect patient-reported data in real time during clinical rotations. Prospective changes in quality of life, selfefficacy, self-care behaviors and mood will be collected quarterly and compared to baseline values every six months. Summary of Results: IRB approval was secured prior to implementation. As of June 2012, 4 student research clinicians have participated in the elective, i.e., two per quarter, and 31 participants had been enrolled in the study, allowing for student participation in over 75 patients interviews. Of the participants enrolled, 18 (58%) were seeking care for type 2 diabetes and 11 (35%) were seeking care for hypertension. Implementation has been smoothly integrated into the flow of routine care. Interim results following the initial six months of implementation are currently under analysis. Conclusion: Creating specific clinical research electives facilitates research opportunities for CAM/IM trainees, and helps provide access to clinical research faculty for mentorship. Using existing health information technology tools, the implementation of prospective clinical research can be efficiently performed in academic CAM/IM settings, enriching student research training, and simultaneously collecting critical data on patient outcomes and quality of care from CAM/IM academic clinics.

Expressive privacy control with pseudonyms

As personal information increases in value, the incentives for remote services to collect as much of it as possible increase as well. In the current Internet, the default assumption is that all behavior can be correlated using a variety of identifying information, not the least of which is a user's IP address. Tools like Tor, Privoxy, and even NATs, are located at the opposite end of the spectrum and prevent any behavior from being linked. Instead, our goal is to provide users with more control over linkability---which activites of the user can be correlated at the remote services---not necessarily more anonymity. We design a cross-layer architecture that provides users with a pseudonym abstraction. To the user, a pseudonym represents a set of activities that the user is fine with linking, and to the outside world, a pseudonym gives the illusion of a single machine. We provide this abstraction by associating each pseudonym with a unique, random address drawn from the IPv6 address space, which is large enough to provide each device with multiple globally-routable addresses. We have implemented and evaluated a prototype that is able to provide unlinkable pseudonyms within the Chrome web browser in order to demonstrate the feasibility, efficacy, and expressiveness of our approach.

Spying on the browser: dissecting the design of malicious extensions

Browsers are a vital component of every computer system as they serve as the interface to the Internet. However, the extensible nature of browsers has facilitated the proliferation of malware infections. In this article, we examine the design of malicious extensions used to steal information from browsers in order to conduct illegal transactions. The focus is on Mozilla's Firefox – but other browsers that share these characteristics will also share similar vulnerabilities. Browsers are a vital component of every computer system as they serve as the interface to the Internet, explain Aditya Sood and Richard Enbody. However, the extensible nature of browsers has facilitated the proliferation of malware infections. Malicious extensions are nothing but a piece of malicious code that installs itself as an inline component in the browser in order to exploit browser capabilities. Since a browser is an integral part of the client-side framework, extensions are platform independent because these extensions communicate with the operating systems using browser access rights. In general, malicious extensions exploit the browser's trust with the website when a user initiates a session. There have been incidents with Mozilla's Firefox browser where malicious extensions were used to steal sensitive information, and bank fraud is one of the targets for these malicious extensions.

A cognitive walkthrough of Autopsy Forensic Browser

PurposeThe purpose of this paper is to review the usability of the Autopsy Forensic Browser in order to improve future versions of this, or similar, tools.Design/methodology/approachThe software Autopsy Forensic Browser was analysed for usability using a cognitive walkthrough approach.FindingsThe results of the evaluation indicate that there are many areas where usability could be improved and these are classified into areas of eight overlapping areas. Examples from each area are presented, with suggestions as to methods to alleviate them.Research limitations/implicationsThe review is limited by the use of the “expert evaluator” approach rather than using a user‐based evaluation. This would tend to mean that some of the usability errors would be “false positives”, while some usability issues were not uncovered. A user‐based evaluation could be a future project.Practical implicationsUsability could be improved of the Autopsy Forensic Browser and developers of such systems should engage with the usability and interaction design community to enhance their software. It would be helpful for users, if future versions of the software take account of the findings of the paper.Originality/valueThis is one of the first reviews of the usability of forensic analysis software and the first for the Autopsy Forensic Browser system. The value is the findings suggest practical ways to enhance usability, which will impact on the effectiveness of investigators.

A Web-Based Solution for Viewing Large-Sized Microscopic Images

This paper demonstrates a pure web-based solution enabling the presentation of scanned pathologic microscopic images on the web. For each slide, an entire specimen is scanned, and a high-resolution digital image (in the order of giga-pixels) is reconstructed. These huge images are then tiled into many 256 x 256-pixel blocks with different resolutions, and information about the blocks of each scanned slide is included in an extensible markup language metafile. Based on the data, a virtual microscopy system is created for viewing the scanned pathologic slides on web. The functionalities (changing viewing resolution, location adjustment, and multimedia annotation presentation) of our virtual slide viewing system are accomplished using pure hypertext markup language (HTML) and JavaScript. We show that there is no need to add plug-in components to browsers in order to handle virtual slides on the web. In a heterogeneous healthcare environment, methods using pure HTML and JavaScript to deal with pathologic content are more appropriate than using proprietary technologies supported only by specific browsers.

Inhibition of superoxide generation from fMLP-stimulated leukocytes by high concentrations of nitric oxide or peroxynitrite: characterization by electron spin resonance spectroscopy

A Corrigendum has been published for this article in Redox Report, Volume 17, Number 1, January 2012, page 47: http://www.ingentaconnect.com/content/maney/rer/2012/00000017/00000001/art00006 (please copy and paste this URL into your web browser in order to link to it)This present study examined the effects of high concentrations of nitric oxide (NO•) and peroxynitrite (ONOO-) on superoxide (O2•-) production from formyl-methionyl-leucyl-phenylalanine (fMLP)-stimulated polymorphonuclear leukocytes (PMNs) by using electron spin resonance (ESR) and spin trapping with 5-(diethoxyphosphoryl)-5-methyl-1-pyrroline-N-oxide (DEPMPO). We demonstrated that ONOO- (100 μM) decreased the ESR signal of DEPMPO-OOH from fMLP-activated PMNs, indicating the inhibition of O2•- generation, while it enhanced the signal of DEPMPO-OH. Inhibition of the respiratory burst was also observed when PMNs were pre-exposed to high concentrations of NO• (100 μM), generated by the NO• donor NOR-1, 30 min prior to stimulation with fMLP. NOR-1 inhibited O2•- generation more effectively under conditions in which ONOO- was formed concurrently. The ability of high concentrations of either ONOO- or NO• to inhibit O2•- generation from fMLP-stimulated PMNs is relevant to pathophysiological conditions, such as severe inflammation, in which NO• or ONOO- production can be significantly elevated.

Dietary overlap between Boer goats and indigenous browsers in a South African savanna

The winter diet of free ranging Boer goats in Valley Bushveld, KwaZulu-Natal, was determined by direct observations and compared with the diet of indigenous browsers (kudu, eland, giraffe, black rhinoceros) in order to determine which browsers are most compatible with goats for ensuring more efficient use of savanna vegetation. Goats were predominantly browsers during winter, spending 73% of their time eating woody plant forage. Principal woody plant species in the diet included Rhus pentheri, Acacia nilotica, Acacia karroo, Euclea crispa and Ziziphus mucronata. Succulents (Aloe ferox and Aloe maculata) were also readily eaten. Highly preferred species were Capparis sepiaria, Phyllanthus verrucosus and Scolopia zeyheri, while Rhoicissus tridentata, Calpurnia aurea, Acacia ataxacantha, Euclea natalensis, Clerodendrum glabrum, Zanthoxylum capense and Hippobromus paucifolia were strongly avoided. Goats fed between ground level and 1m, with an average feeding height of 0.67m. The diet and feeding height of kudu and goats and of black rhinoceros and goats overlapped to a large extent suggesting that they are potential competitors for food resources. Similarly, overlap in diet between giraffe and goats was extensive, but overlap in feeding height was small. The potential for competition appeared to be the least between goats and eland because, despite feeding at similar heights, they generally consumed different species. A mixed farming system which includes goats, eland and giraffe is proposed as a useful management tool for using savanna vegetation more efficiently.

투명 캐시에서의 사용자 인증 시스템 구현

최근의 프록시 서버에서 사용자 인증에 의한 접근제어를 위해서는 각 사용자 브라우저마다 프록시 서버 설정을 해주어야만 하는 불편함이 있다. 본 논문에서 구현한 투명캐시에서의 사용자 인증 기술은 간단히 캐시서버 상에 인증기능 옵션을 설정함으로써 모든 사용자에게는 투명하게 인터넷을 사용할 수 있도록 하였다. 또한 관리자 측면에서는 각 사용자의 트래픽을 감시하고 보안성을 한층 강화하는 효과를 보인다. 그리고 사용자의 인터넷 사용습관을 모니터링 할 수 있어 쇼핑몰과 같은 전자상거래 분야에서 사용자의 성향에 따른 인터넷 전자 고객관계관리(eCRM) 서비스에 활용할 수 있을 것으로 기대된다 단 기술은 별도로 보안장비의 추가설치 없이 보안이 필수적인 기업 부설 연구소, 전자상거래 웹사이트, 군부대의 인터넷 환경 등에서도 적용할 수 있는 기술이라 하겠다. There are recently a lot of inconvenience because every client should be set to the proxy server on the browser in order to control the access by means of the client authentication in the proxy server. The client authentication technology using the transparency cache in this paper will be transparently used for every user in the internet which option of the authentication function is simply set in the cache server. In addition, the administrator will get the benefit since he can control the traffic of each client and strengthen the security. And also, this system is expected to use in the eCRM deeply rotated to the tendency of the client in the field of the e-commerce like shopping mall in the internet since the administrator can monitor the pattern of the client using the internet. This technique can be applied to the company affiliated research center, the EC website, and the military where it is essential for the tight security even though there are no additional security devices.

A web page transmission mechanism with transmission order control of inline objects

AbstractDue to the increasing popularity of the Internet, the WWW (World Wide Web) has become the most popular way to distribute multimedia contents. In the WWW, impressive information can be provided by embedding a large number of inline objects such as images in a WWW page. Since these inline objects are generally presented in WWW browsers in transmission order, the transmission order of inline objects becomes very important, especially for users accessing the Internet with a low‐speed connection such as a dial‐up line. In this paper, we propose a page transmission mechanism, which allows content authors to specify the transmission order of inline objects in WWW pages. First, we define a language to specify the transmission order of inline objects based on XML (Extensible Markup Language). We then discuss how we can implement the transmission order control, and propose a new protocol, HTSP (Hypertext Streaming Protocol), which realizes efficient transmission of ordered inline objects. © 2002 Wiley Periodicals, Inc.

SharedWeb—a shared virtual environment over the World Wide Web

The design, implementation and experimental results of a multiple-user 3D web-browsing system, called the SharedWeb system, are described in this paper. The system is based on the request–response method of the WWW server. The key features of this system include the ability of the WWW server to remember all the browsers connected to it in order to transmit the messages required to maintain consistent states among browsers. The dead-reckoning technique of distributive interactive simulation (DIS) is used by browsers in order to reduce the number of messages sent onto the network and to satisfy the timing requirement demanded by the virtual environment. The protocol data unit (PDU) defined in DIS is also adapted by the SharedWeb system not only to communicate information among browsers but also to integrate with the DIS environment in the near future. © 1998 John Wiley & Sons, Ltd.
