E. Chovancová, Z. Dudláková, O. Fortotira, J. Radusovsky
Biometrics deals with technology of measuring and analyzing biological data. In informatics, biometry refers to technologies that measure and analyze human body characteristics, such as a DNA, a fingerprint, a retina or iris, a voice patterns, a facial patterns and hand, for authentication purposes. This work points out the suggestion of a specialized processor focused on sound biometrics using Dynamic Time Warping method. This method is based on an analysis of the issue for most effective solution in VHDL. This method deals with recognition of certain words in the sentences, which are compared with stored templates. Therefor is it in terms of programming most appropriate and reasonable for processor design.
生物计量学研究的是测量和分析生物数据的技术。在信息学中,生物计量学是指测量和分析人体特征的技术,如DNA、指纹、视网膜或虹膜、声音模式、面部模式和手,以进行身份验证。本文提出了一种基于动态时间扭曲方法的声音生物识别处理器的建议。该方法是基于对问题的分析,在VHDL中进行最有效的解决。该方法处理对句子中特定单词的识别,并将其与存储的模板进行比较。因此,它在编程方面是最合适和合理的处理器设计。

Students with practical software project experience perform better at related university subjects — A truth or a myth? 有实际软件项目经验的学生在相关大学科目上表现更好——这是事实还是神话?
C. Szabó, A. Bollin
There is an ongoing discussion about the pros and cons of allowing Bachelor and Master students to become employees at companies and to work besides their study. Even more, in the field of Software Engineering, this issue is even seen as a prerequisite. However, are such students really achieving better results in their studies? In this paper, we deal with this question at least from the perspective of Software Project Management skills. We start with the hypothesis that their work (and project) experience yields to better results in a lecture dealing with these topics. Then we describe the setting of a first pre-study, which was embedded in a lecture about software quality and management at the Technical University of Košice. Next, we discuss the results. In our setting, it turned out that the difference is marginal in average. Even though the scores of students with previous practical experience are not so diverse at the beginning of the lecture, students with prior experience perform slightly better at the end of the course.
关于允许学士和硕士学生成为公司员工并在学习之余工作的利弊正在进行讨论。甚至,在软件工程领域,这个问题甚至被视为一个先决条件。然而,这样的学生真的在学习上取得了更好的成绩吗?在本文中,我们至少从软件项目管理技能的角度来处理这个问题。我们首先假设他们的工作(和项目)经验会在处理这些主题的讲座中产生更好的结果。然后,我们描述了第一个预研究的设置,该预研究嵌入在Košice技术大学关于软件质量和管理的讲座中。接下来,我们讨论结果。在我们的设置中,结果表明,平均而言,这种差异是微乎其微的。虽然有过实践经验的学生在课程开始时的分数差异不大,但有过实践经验的学生在课程结束时的表现略好。

Using social networks for supervising and mentoring 利用社交网络进行监督和指导
M. Bačíková
In this paper we describe the experience of the high school and university teachers with using social networks for supervising. We aimed at mentoring of small groups such as student theses and group projects. To support our claims, we performed a qualitative and quantitative study along with an experiment of using social networks in supervising. The studies were answered by multiple high school and university students and teachers. The results of the studies and the experiment are described in this paper. Although social networks have the potential to be used in supervising, they also have a lot of disadvantages making their adoption harder. Existing solutions such as Ning resolved some of these issues, but they are not tailored for supervising. To answer to the results, we describe an outline of the future prototype as a possible solution. We believe that integration of existing solutions is the key to achieve successful results. In our future research, we will leverage not only from the knowledge of the target group of university and high school teachers, but we will also apply experience from practice by cooperating with the Fpt Slovakia, s.r.o. company with the aim of directly preparing students for practice. This paper emerged from the cooperation of the Technical university of Košice, Ostrovského high school and the software company Fpt Slovakia, s.r.o.
本文描述了高校教师运用社交网络进行督导的经验。我们的目标是指导小团体,如学生论文和小组项目。为了支持我们的观点,我们进行了定性和定量研究,并进行了使用社交网络进行监督的实验。这些研究是由多名高中和大学的学生和教师回答的。本文介绍了研究结果和实验结果。虽然社交网络有可能被用于监督,但它们也有很多缺点,使得它们更难被采用。现有的解决方案(如Ning)解决了其中的一些问题,但它们并不适合监管。为了回答这些结果,我们描述了未来原型的轮廓,作为一种可能的解决方案。我们认为,整合现有的解决方案是取得成功的关键。在我们未来的研究中,我们不仅将利用大学和高中教师这一目标群体的知识,还将通过与Fpt Slovakia, s.r.o.公司合作,应用实践中的经验,目的是直接为学生的实践做好准备。本文源于Košice技术大学、ostrovsk高中和软件公司Fpt Slovakia, s.r.o的合作。

P. Segec, P. Paluch, J. Papán, M. Kubina
The interest in integrating real-time and realtime multimedia communication features into IP networks and its applications, the web including, started a development effort, which brings several new communication technologies. These technologies are influencing many aspects of our lives now, education not excluding. The Session Initiation Protocol (SIP) and the Web Real-Time Communication (WebRTC) belongs among the most important. Both of them allow us, the teachers, communicate with our students through audio and video. In this paper we provide a technological overview describing the aspects of integration of these two important internet technologies, SIP with WebRTC. Both together used to easily extend any web based e-learning or collaboration environment for unlimited communication experiences.

Use case driven educational content modeling with UML 用UML进行用例驱动的教育内容建模
J. Lang, M. Cervenak
Considering an absence of formalization in educational content notation analysis and design on the contrary of other fields, where modeling plays irreplaceable role we have performed certain experiments. We have abstracted certain equivalence between graduate profile and a profession profile. Subsequently we have substituted this profiles as a system of a knowledge, ability, skills etc. Applied substitution between profiles and a system allows us to treat it in analogy with software engineering process - Unified Process which describes how requirements are turned into educational content. Such approach leads to models with zero redundancy which is very important for educational content even for computer aided education or distance learning. The results of our experiment experiment we have examined also by short short questionnaire.
考虑到教育内容符号分析与设计缺乏形式化,与其他领域不同,建模在其中起着不可替代的作用,我们进行了一定的实验。我们抽象出了毕业生形象与职业形象之间的某种对等关系。随后,我们将这些档案替换为知识、能力、技能等的系统。在概要文件和系统之间应用替代允许我们以软件工程过程的类比来对待它——统一过程描述了需求如何转化为教育内容。这种方法产生了零冗余的模型,这对于教育内容甚至计算机辅助教育或远程学习都是非常重要的。我们的实验结果我们也通过简短的问卷调查来检验。

Use of virtual excursions at secondary schools in Slovakia 在斯洛伐克的中学使用虚拟短途旅行
K. Pribilová, Viola Gazdikova, R. Horváth
Current situation in implementing real excursions at secondary schools is limited by several factors. On one hand, it is the content of the discipline and its assigned time dotation that does not enable implementation of real excursions because of reasons of time; on the other hand, it regards economical limitations, for instance, which prevent students from seeing real environment that would be related to the educational content. Implementation of real excursions is often time-consuming. For the purposes of the future practice of the secondary school graduates it is necessary so that they had opportunities to get acquainted with real environment of their future profession, or opportunities to get acquainted with real professional environment that can influence their future profiling, selection of further education (university education, etc.). Based on the existence of limiting factors in implementation of real excursions and on the need of excursions as a stimulator for further education and work placement of secondary school graduates there emerges the intention of creation of interactive virtual excursions, which could be used both in formal education as a didactic aid based on new technologies and also in extracurricular activities.
中学实施实地考察的现状受到几个因素的制约。一方面,由于时间的原因,这门学科的内容和它所分配的时间不允许实施真正的短途旅行;另一方面,它考虑到经济的限制,例如,这使学生无法看到与教育内容相关的真实环境。实现真正的短途旅行通常是耗时的。为了中学毕业生未来实践的目的,有必要使他们有机会了解他们未来职业的真实环境,或者有机会了解能够影响他们未来概况,选择继续教育(大学教育等)的真实职业环境。基于现实漫游实施中存在的限制因素,以及将漫游作为中学毕业生继续教育和工作安排的刺激物的需要,产生了创建交互式虚拟漫游的意图,它既可以在正式教育中作为基于新技术的教学辅助手段,也可以在课外活动中使用。

Analysis of students behaviour in virtual environment 虚拟环境下学生行为分析
J. Reichel, P. Kuna
The analysis of students behaviour in web learning environment within distance learning is one of the most significant areas for learning optimization. The aim of this article is to analyse students behaviour and the use of e-learning course in subject Discrete Mathematics. Data and results of this analysis are important for further adjustment and improvement of the e-course. Results of the course traffic analysis were estimated using association rules Discrete mathematics is compulsory for both bachelor and master study program Applied Informatics in full-time and distance form of study as well as bachelor and master study program Teaching of academic subjects in full-time and distance form of study. This electronic course is designed to use linear and branched teaching programs. In compiling the course we tried to take into consideration target audience - students of Computer Science. The course is designed to not require any special knowledge in IT field. Discrete Mathematics Course 1 consists of 10 thematic units (areas) replicating the length of the semester in weeks. Authors describe detail analysis of students behaviour which is made of data taken from LMS MOODLE database. We used specific types of data, which are indicating user traffic on every single page of the course. We used a log file that contains records of e-learning course with 107 students. To identify sessions, we used the STT (Session Timeout Threshold). Purpose of session identification is to divide access of all users into separate sessions (relations). Session side-effect may exclude users who are behind a NAT or proxy device. So we can identify users who are sharing a single computer, for example in a library. Students who used the e-course of Discrete Mathematics 1 were more successful in the final examination. The fact that the course is effective does not mean that all activities have been fully utilized. Based on the results of our analysis, we can optimize and improve the e-course and bring it closer to the student's needs. After implementation of necessary changes we can evaluate impact of these changes in the efficacy of the course.
远程学习中网络学习环境下学生行为的分析是学习优化的重要研究领域之一。本文的目的是分析离散数学科目中学生的行为和电子学习课程的使用情况。该分析的数据和结果对进一步调整和完善电子课程具有重要意义。使用关联规则估计课程流量分析的结果离散数学是全日制和远程学习的学士和硕士课程的必修课程应用信息学以及全日制和远程学习的学士和硕士课程的学术科目教学。本电子课程设计采用线性和分支教学方案。在编写课程时,我们尽量考虑到目标受众——计算机科学专业的学生。本课程不需要任何IT领域的专业知识。离散数学课程1由10个主题单元(区域)组成,以周为单位复制学期的长度。作者对LMS MOODLE数据库中的学生行为进行了详细的分析。我们使用了特定类型的数据,这些数据显示了课程中每一页的用户流量。我们使用了一个日志文件,其中包含107名学生的电子学习课程记录。为了识别会话,我们使用了STT(会话超时阈值)。会话标识的目的是将所有用户的访问划分为单独的会话(关系)。会话副作用可能会排除NAT或代理设备后面的用户。因此,我们可以识别共享一台计算机的用户,例如在图书馆中。使用离散数学1电子课程的学生在期末考试中更成功。课程有效并不意味着所有的活动都得到了充分利用。根据我们的分析结果,我们可以优化和改进电子课程,使其更接近学生的需求。在实施必要的变更后,我们可以评估这些变更对课程有效性的影响。

Examination of the theta index during solving IT issues 在解决IT问题时检查theta指数
J. Depešová, H. Noga, M. P. Silarska, K. Pytel
The theta waves are formed in the thalamus and in the limbic system. It seems, it is linked with a data retrieval from the memory along with ability to impulse control. These waves dominate in EEG scan from 6 months of life till the age of 6-7. At elderly people the dominance of these waves can be related to drowsiness and excluding from discussion and fully awareness of environment. In the theta state person can think very creatively because it's related with the hypnologic state of mind. These waves can be also observed during visualization. The theta state lies on the edge of our consciousness. In Biofeedback, they are associated with the deepest level of meditation. The Theta is also considered as entrance to memory and learning ability. [1-4] Theta meditation increase creativity and allow learning faster. Theta reduce stress level, unlock the understanding, and other none physical senses. It also helps to release the endorphins, strengthening the immune system.
θ波在丘脑和大脑边缘系统中形成。它似乎与从记忆中检索数据以及控制冲动的能力有关。这些波在6个月大到6-7岁的脑电图扫描中占主导地位。在老年人中,这些波的主导地位可能与困倦和排除讨论和完全意识到环境有关。在θ波状态下,人们可以非常有创造性地思考,因为它与心理的生理状态有关。在可视化过程中也可以观察到这些波。θ波状态位于我们意识的边缘。在生物反馈中,它们与最深层次的冥想有关。Theta也被认为是记忆和学习能力的入口。[1-4] θ波冥想可以提高创造力,加快学习速度。θ波可以减轻压力,开启理解,以及其他非生理感官。它还有助于释放内啡肽,增强免疫系统。
