In the present times, the healthcare sector has seen an enormous growth in the usage of technology ranging from EHRs (electronic health records) to personal health trackers. Currently, there is a need for managing EHRs effectively with respect to storage, privacy and security measures. State-of-art technologies such as blockchain and artificial intelligence (AI) are applied in the healthcare domain. Innovation in AI is steadily advancing and is finding its place in different industries. The integration of blockchain and AI looks promising as there are several benefits. Blockchain can make the AI more secure and autonomous whereas AI can drive the blockchain with intelligence. The objective of this article is to explore the uses of blockchain as well as AI technology in the field of healthcare. We aim to survey the advantages, issues and challenges of integrating blockchain with AI technology, including future research directions in the healthcare domain. In this study, Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) rules and an efficient searching protocol were used to examine several scientific databases to recognize and investigate every important publication. A solid systematic review was carried out on integration of blockchain and AI in the healthcare domain to identify existing challenges and benefits of integrating these two technologies in healthcare. Our study found that the integration of AI and blockchain technology has a potential to provide several benefits in terms of performance and security which conventional EHRs lack. The inherent benefits of blockchain and AI together are limitless, but the bare outcomes based on blockchain powered by AI technology are yet to be obtained. In addition, the outcome of our detailed study may aid researchers to carry out further research.

The increase in data diversity and the fact that database design is a difficult process make it practically impossible to design a unique database schema for all datasets encountered. In this paper, we introduce a fully automatic genetic algorithm-based relational database normalization method for revealing the right database schema using a raw dataset and without the need for any prior knowledge. For measuring the performance of the algorithm, we perform a simulation study using 250 datasets produced using 50 well-known databases. A total of 2500 simulations are carried out, ten times for each of five denormalized variations of all database designs containing different synthetic contents. The results of the simulation study show that the proposed algorithm discovers exactly 72% of the unknown database schemas. The performance can be improved by fine-tuning the optimization parameters. The results of the simulation study also show that the devised algorithm can be used in many datasets to reveal structs of databases when only a raw dataset is available at hand.
数据多样性的增加以及数据库设计是一个困难的过程,使得为遇到的所有数据集设计一个独特的数据库模式实际上是不可能的。在本文中,我们介绍了一种基于全自动遗传算法的关系数据库规范化方法,该方法使用原始数据集,在不需要任何先验知识的情况下,揭示正确的数据库模式。为了测量算法的性能,我们使用使用50个知名数据库生成的250个数据集进行了模拟研究。总共进行了2500次模拟,对于包含不同合成内容的所有数据库设计的五个非规范化变体中的每一个,都进行了十次模拟。仿真研究结果表明,该算法准确地发现了72%的未知数据库模式。可以通过微调优化参数来提高性能。仿真研究的结果还表明,当手头只有原始数据集时,所设计的算法可以在许多数据集中使用,以揭示数据库的结构。

Low qualification of employees newly hired to service desks contributes to the high turnover of service desk agents and consequently to low quality of services delivered. This paper proposes a conceptual artefact comprising two modules for tacit knowledge elicitation and knowledge transfer during the onboarding training process. The design of the artefact follows the design science methodology. Ex-ante evaluation methods are chosen to evaluate the importance of a problem domain and evaluate the artefact feasibility. Expert interviews and focus group discussions with experts from the field were performed to support the evaluation activities. The proposed framework uses eye-tracking technology to complement captured knowledge with tacit knowledge. Next, the proposed model incorporates a simulated environment for enhanced training experience and effective knowledge transfer from expert employees to novice ones. This paper and the proposed artefact aim to improve the training process of service desk employees and to contribute to wider use of tacit knowledge capture and elicitation techniques in IT service management.

Increasing Efficiency in Inventory Control of Products with Sporadic Demand Using Simulation 利用仿真方法提高零星需求产品库存控制效率
Q4 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2022-08-19 DOI: 10.18267/j.aip.184
K. Hušková, J. Dyntar
The goal of this paper is to examine whether, in Q-system inventory control policy, a combination of the reorder point exceeding order quantity leads to minimal holding and ordering costs when dealing with sporadic demand. For this purpose, a past stock movement simulation is applied to a set of randomly generated data with different numbers of zero demand periods ranging from 10 to 90%. The outputs of the simulation prove that in situations where stock holding costs are too high, the simulation tends to reduce average stock by overcoming periods between two demand peaks with an increase in the numbers of small replenishment orders and reaches lower stock holding and ordering costs. Furthermore, the correlation analysis proves that there is a statistically significant relationship (r = .847, p = .004) between the number of time series that reach minimal holding and ordering costs under the control of reorder point (replenishment order) and the demand standard deviation affected by the evolving sporadicity. These findings can support decision making linked with inventory management of products with sporadic demand and contribute to development of business information systems.
本文的目的是检验在q系统库存控制策略中,当处理零星需求时,再订货点超过订单数量的组合是否会导致最小的持有和订购成本。为此,将过去的股票运动模拟应用于一组随机生成的数据,这些数据具有从10%到90%不等的不同数量的零需求期。仿真结果证明,在库存成本过高的情况下,通过克服两个需求高峰之间的时间间隔,增加小补货订单数量,仿真结果倾向于降低平均库存,达到较低的库存和订购成本。进一步,相关分析证明,在再订货点(补货顺序)控制下达到最小持有量的时间序列数与订货成本与受偶发性影响的需求标准差之间存在显著的相关关系(r = 0.847, p = 0.004)。这些发现可以支持与零星需求产品的库存管理有关的决策,并有助于商业信息系统的发展。

Machine learning methods are used for purposes such as learning and estimating a feature or parameter sought from a dataset by training the dataset to solve a particular problem. The transfer learning approach, aimed at transferring the ability of people to continue learning from their past knowledge and experiences to computer systems, is the transfer of the learning obtained in the solution of a particular problem so that it can be used in solving a new problem. Transferring the learning obtained in transfer learning provides some advantages over traditional machine learning methods, and these advantages are effective in the preference of transfer learning. In this study, a total of 1980 eye contour images of 96 different people were collected in order to solve the problem of recognizing people from their eye images. These collected data were classified in terms of person, age and gender. In the classification made for eye recognition, feature extraction was performed with 32 different transfer learning algorithms in the Python program and classified using the RandomForest algorithm for person estimation. According to the results of the research, 30 different classification algorithms were used, with the ResNet50 algorithm being the most successful, and the data were also classified in terms of age and gender. Thus, the highest success rates of 83.52%, 96.41% and 77.56% were obtained in person, age and gender classification, respectively. The study shows that people can be identified only by eye images obtained from a smartphone without using any special equipment, and even the characteristics of people such as age and gender can be determined. In addition, it has been concluded that eye images can be used in a more efficient and practical biometric recognition system than iris recognition.
机器学习方法用于诸如通过训练数据集来解决特定问题来学习和估计从数据集寻求的特征或参数之类的目的。迁移学习方法旨在将人们从过去的知识和经验中继续学习的能力转移到计算机系统中,是将在解决特定问题时获得的知识转移到解决新问题中。与传统的机器学习方法相比,迁移学习中获得的学习提供了一些优势,这些优势在迁移学习的偏好中是有效的。在这项研究中,为了解决从眼睛图像中识别人的问题,共收集了96个不同人群的1980幅眼睛轮廓图像。这些收集到的数据按个人、年龄和性别进行了分类。在为眼睛识别进行的分类中,在Python程序中使用32种不同的迁移学习算法进行特征提取,并使用RandomForest算法进行人估计分类。根据研究结果,使用了30种不同的分类算法,其中ResNet50算法最为成功,数据还按年龄和性别进行了分类。因此,在个人、年龄和性别分类中,成功率分别为83.52%、96.41%和77.56%。研究表明,在不使用任何特殊设备的情况下,只需通过智能手机获得的眼睛图像就可以识别人,甚至可以确定人的年龄和性别等特征。此外,已经得出结论,眼睛图像可以用于比虹膜识别更高效和实用的生物特征识别系统。

Skin cancer is undoubtedly one of the deadliest diseases, and early detection of this disease can save lives. The usefulness and capabilities of deep learning in detecting and categorizing skin cancer based on images have been investigated in many studies. However, due to the variety of skin cancer tumour shapes and colours, deep learning algorithms misclassify whether a tumour is cancerous or benign. In this paper, we employed three different pre-trained state-of-the-art deep learning models: DenseNet121, VGG19 and an improved ResNet152, in classifying a skin image dataset. The dataset has a total of 3297 dermatoscopy images and two diagnostic categories: benign and malignant. The three models are supported by transfer learning and have been tested and evaluated based on the criteria of accuracy, loss, precision, recall, f1 score and ROC. Subsequently, the results show that the improved ResNet152 model significantly outperformed the other models and achieved an accuracy score of 92% and an ROC score of 91%. The DenseNet121 and VGG19 models achieve accuracy scores of 90% and 79% and ROC scores of 88% and 75%, respectively. Subsequently, a deep residual learning skin cancer recognition (ResNetScr) system has been implemented based on the ResNet152 model, and it has the capacity to help dermatologists in diagnosing skin cancer.
皮肤癌无疑是最致命的疾病之一,早期发现这种疾病可以挽救生命。深度学习在基于图像的皮肤癌检测和分类中的有用性和能力已经在许多研究中进行了调查。然而,由于皮肤癌肿瘤的形状和颜色的多样性,深度学习算法会错误地区分肿瘤是癌性的还是良性的。在本文中,我们使用了三种不同的预训练的最先进的深度学习模型:DenseNet121, VGG19和改进的ResNet152,对皮肤图像数据集进行分类。该数据集共有3297张皮肤镜图像和两种诊断类别:良性和恶性。这三种模型都得到了迁移学习的支持,并根据准确率、损失、精度、召回率、f1分数和ROC标准进行了测试和评估。随后,结果表明,改进后的ResNet152模型显著优于其他模型,准确率得分为92%,ROC得分为91%。DenseNet121和VGG19模型的准确率得分分别为90%和79%,ROC得分分别为88%和75%。随后,基于ResNet152模型实现了深度残差学习皮肤癌识别(ResNetScr)系统,该系统具有帮助皮肤科医生诊断皮肤癌的能力。

Blockchain is regarded as a significant innovation and shows a set of promising features that can certainly address existing issues in real time applications. Decentralization, greater transparency, improved traceability and secure architecture can revolutionize healthcare systems. With the help of advancement in computer technologies, most healthcare institutions try to store patient data digitally rather than on paper. Electronic health records are regarded as some of the most important assets in healthcare system and are required to be shared among different hospitals and other organizations to improve diagnosis efficiency. While sharing patients’ details, certain basic standards such as integrity and confidentiality of the information need to be considered. Blockchain technology provides the above standards with features of immutability and granting access to stored information only to authorized users. The examination approach depends on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (or PRISMA) rules and an efficient planned search convention is utilized to look through multiple scientific databases to recognize, investigate and separate every important publication. In this paper, we present a solid systematic review on the blockchain and healthcare domain to identify the existing challenges and benefits of applying blockchain technology in healthcare systems. More than 150 scientific papers published in the last ten years are surveyed, resulting in the identifications and summarization of observations made on the different privacy-preserving approaches and also assessment of their performances. We also present a significant architectural solutions of blockchain to achieve interoperability. Thereby, we attempt to analyse the ideas of blockchain in the medical domain, by assessing the advantages and limitations, subsequently giving guidance to other researchers in the area.
区块链被认为是一项重大创新,它展示了一系列有前景的功能,这些功能肯定可以解决实时应用中存在的问题。去中心化、更大的透明度、改进的可追溯性和安全的架构可以彻底改变医疗系统。在计算机技术进步的帮助下,大多数医疗机构都试图以数字方式而不是纸质方式存储患者数据。电子健康记录被认为是医疗系统中最重要的资产之一,需要在不同的医院和其他组织之间共享,以提高诊断效率。在分享患者的详细信息时,需要考虑某些基本标准,如信息的完整性和机密性。区块链技术为上述标准提供了不变性和只允许授权用户访问存储信息的功能。审查方法取决于系统评价和荟萃分析的首选报告项目(或PRISMA)规则,并利用高效的计划搜索惯例来浏览多个科学数据库,以识别、调查和分离每一份重要出版物。在本文中,我们对区块链和医疗保健领域进行了系统的回顾,以确定在医疗保健系统中应用区块链技术的现有挑战和好处。对过去十年中发表的150多篇科学论文进行了调查,对不同隐私保护方法的观察结果进行了识别和总结,并对其性能进行了评估。我们还提出了一个重要的区块链架构解决方案,以实现互操作性。因此,我们试图通过评估区块链在医学领域的优势和局限性来分析区块链的思想,随后为该领域的其他研究人员提供指导。

Blockchain technology provides the above standards with features of immutability and granting access to stored information only to authorized users. The examination approach depends on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (or PRISMA) rules and an efficient planned search convention is utilized to look through multiple scientific databases to recognize, investigate and separate every important publication. In this paper, we present a solid systematic review on the blockchain and healthcare domain to identify the existing challenges and benefits of applying blockchain technology in healthcare systems. More than 150 scientific papers published in the last ten years are surveyed, resulting in the identifications and summarization of observations made on the different privacy-preserving approaches and also assessment of their performances. We also present a significant architectural solutions of blockchain to achieve interoperability. Thereby, we attempt to analyse the ideas of blockchain in the medical domain, by assessing the advantages and limitations, subsequently giving guidance to other researchers in the area.","PeriodicalId":36592,"journal":{"name":"Acta Informatica Pragensia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49595492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classification is a crucial stage in identification systems, most specifically in biometric identification systems. A weak and inaccurate classification system may produce false identity, which in turn impacts negatively on delicate decisions. Decision making in biometric systems is done at the classification stage. Due to the importance of this stage, many classifiers have been developed and modified by researchers. However, most of the existing classifiers are limited in accuracy due to false representation of image features, improper training of classifier models for newly emerging data (over-fitting or under-fitting problem) and lack of an efficient mode of generating model parameters (scalability problem). The Negative Selection Algorithm (NSA) is one of the major algorithms of the Artificial Immune System, inspired by the operation of the mammalian immune system for solving classification problems. However, it is still prone to the inability to consider the whole self-space during the detectors/features generation process. Hence, this work developed an Optimized Negative Selection Algorithm (ONSA) for image classification in biometric systems. The ONSA is characterized by the ability to consider whole feature spaces (feature selection balance), having good training capability and low scalability problems. The performance of the ONSA was compared with that of the standard NSA (SNSA), and it was discovered that the ONSA has greater recognition accuracy by producing 98.33% accuracy compared with that of the SNSA which is 96.33%. The ONSA produced TP and TN values of 146% and 149%, respectively, while the SNSA produced 143% and 146% for TP and TN, respectively. Also, the ONSA generated a lower FN and FP rate of 4.00% and 1.00%, respectively, compared to the SNSA, which generated FN and FP values of 7.00% and 4.00%, respectively. Therefore, it was discovered in this work that global feature selection improves recognition accuracy in biometric systems. The developed biometric system can be adapted by any organization that requires an ultra-secure identification system. O.S.O.:
分类是识别系统中的一个关键阶段,尤其是在生物识别系统中。一个薄弱和不准确的分类系统可能会产生虚假的身份,从而对微妙的决策产生负面影响。生物识别系统的决策是在分类阶段完成的。由于这一阶段的重要性,研究人员开发和修改了许多分类器。然而,由于图像特征的错误表示、对新出现的数据的分类器模型的不当训练(过拟合或欠拟合问题)以及缺乏生成模型参数的有效模式(可伸缩性问题),大多数现有分类器的准确性受到限制。负选择算法(NSA)是人工免疫系统的主要算法之一,其灵感来源于哺乳动物免疫系统解决分类问题的操作。然而,在检测器/特征生成过程中,仍然容易无法考虑整个自空间。因此,本工作开发了一种用于生物识别系统中图像分类的优化负选择算法(ONSA)。ONSA的特点是能够考虑整个特征空间(特征选择平衡),具有良好的训练能力和较低的可扩展性问题。将ONSA与标准NSA(SNSA)的性能进行了比较,发现ONSA的识别准确率为98.33%,而标准NSA的识别准确度为96.33%。此外,与分别产生7.00%和4.00%的FN和FP值的SNSA相比,ONSA分别产生4.00%和1.00%的较低FN和FP率。因此,在这项工作中发现,全局特征选择提高了生物识别系统的识别精度。所开发的生物识别系统可以由任何需要超安全身份识别系统的组织进行调整。O.S.O.:

What is the Real Threat of Information Explosion? 信息爆炸的真正威胁是什么?
Q4 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2022-07-23 DOI: 10.18267/j.aip.185
Petr Strossa
The text is devoted to a consideration of the “information explosion” phenomenon. The exponential growth of publications is compared to the (similarly exponential) growth of population, especially in the countries where most of the publications are created. The increasing tertiary education gross enrolment ratio (naturally associated with involvement in the publication process) is also taken into account. The text comes to a conclusion that either the exponential growth of publications must decrease its base value in our future, or we are heading towards a time point where an increasing number of publications find no readers (if that point is not yet behind us).
本文致力于对“信息爆炸”现象的思考。出版物的指数增长与人口的(同样指数的)增长进行了比较,特别是在出版大多数出版物的国家。不断增加的高等教育毛入学率(自然与参与出版过程有关)也被考虑在内。本文得出的结论是,要么出版物的指数增长必然会在我们的未来降低其基础价值,要么我们正走向一个时间点,越来越多的出版物找不到读者(如果那个点还没有过去的话)。
