There is a lack of extensive research on the development of smart universities (SU). The aim of this paper is to investigate the impact of knowledge management (KM) on the development of SU (DSU) in Iraq. According to the knowledge-based view (KBV), resource-based view (RBV), and KM capability model, this study suggests that the KM process (KMP) and KM infrastructure (KMI) have a positive impact on SUs development. Furthermore, the study suggests that KMI functions as a mediator. The study was conducted using a sample of five public universities in Iraq. A purposive sampling method was utilised to collect data from a total of 209 academic staff members. The study's results demonstrate that KMP (knowledge acquisition, knowledge sharing, and knowledge application) and KMI (IT infrastructure and human KM) have a significant impact on the DSU. Additionally, it was discovered that KMI plays a role in mediating the influence of KMP on the DSU. The findings indicate that successful KM can support the progress of SU. Further cross-national and variable-based studies are required to enhance the validity of this conclusion.
对智慧大学的发展缺乏广泛的研究。本文的目的是研究知识管理(KM)对伊拉克知识管理(DSU)发展的影响。基于知识基础观(KBV)、资源基础观(RBV)和知识管理能力模型,本文认为知识管理过程(KMP)和知识管理基础设施(KMI)对知识管理系统的发展具有正向影响。此外,研究表明,KMI作为一个中介。这项研究以伊拉克五所公立大学为样本进行。采用有目的的抽样方法对209名教职员进行数据收集。研究结果表明,知识获取、知识共享和知识应用(KMP)和IT基础设施和人力知识管理(KMI)对企业决策单元有显著影响。此外,还发现KMI在KMP对DSU的影响中起中介作用。研究结果表明,成功的知识管理可以支持知识管理的发展,需要进一步的跨国和基于变量的研究来提高这一结论的有效性。

Since 1989, various initiatives aimed at supporting humanity, linguistic, information, technical or polytechnical education in basic schools in Slovakia (i.e. at primary and lower secondary schools according to ISCED) were announced and implemented. At the end of 2020 the Ministry of Education, Science, Research and Sport of the Slovak Republic announced its intention to carry out a curricular reform on the level of ISCED 1 and ISCED 2. The article presents starting points and conceptions of both the previous as well as the announced curricular reforms, and subsequently the authors focus on the impact of these reforms on the content of the subject of technology, in frame of which technical education of students at lower level of secondary education is carried out. From the authors' point of view, the curricular reform of the subject of technology should increase students' interest in technically oriented fields of study. In this context, they present results of a research study, the purpose of which was to determine how students evaluate the current content (before the announced reform) of the technology subject.
自1989年以来,斯洛伐克宣布并实施了旨在支持基础学校(即《国际教育标准分类法》规定的小学和初中)的人文、语言、信息、技术或理工教育的各种举措。2020年底,斯洛伐克共和国教育、科学、研究和体育部宣布,打算在《国际教育标准分类法》1级和《国际教育水平分类法》2级进行课程改革。本文介绍了之前和宣布的课程改革的出发点和概念,随后作者重点讨论了这些改革对技术学科内容的影响,在这个框架下,对中等教育水平较低的学生进行技术教育。从作者的观点来看,技术学科的课程改革应该提高学生对技术专业的兴趣。在这种情况下,他们介绍了一项研究的结果,目的是确定学生如何评估技术科目的当前内容(在宣布改革之前)。

Nutrients are essential to optimising plant growth. However, the introduction of fertiliser in a hydroponics setup influences the pH level of the nutrient solution. This, in turn, could affect plants' growth as many types of plants require a specific pH range to grow optimally. Conventional hydroponics cultivation performs pH adjustment manually – a meticulous and error-prone process. Manual adjustment of pH solutions is prone to estimation errors, particularly when the pH levels change drastically due to the slow response of the solution to the addition of alkaline or acidic mixtures and sensitivity to minute errors in mixture delivery. For these reasons, a model to estimate the solution's pH would help improve the delivery accuracy of the alkaline and acidic mixtures. Past research offers minimal study to optimally construct the model from a System Identification (SI) perspective. This study represents a pH water neutralisation behaviour using the Nonlinear Autoregressive model with Exogeneous Inputs (NARX). The project begins with input and output data acquisition, leading to the development of the NARX model. Model performance was then evaluated by analysing the model fit and residual distribution.
营养素对优化植物生长至关重要。然而,在水培设置中引入化肥会影响营养液的pH水平。这反过来又可能影响植物的生长,因为许多类型的植物需要特定的pH范围才能最佳生长。传统的水培栽培是手动调节pH值的,这是一个细致且容易出错的过程。手动调节pH溶液容易产生估计误差,特别是当pH水平由于溶液对添加碱性或酸性混合物的反应缓慢以及对混合物输送中微小误差的敏感性而急剧变化时。由于这些原因,估计溶液pH的模型将有助于提高碱性和酸性混合物的输送精度。过去的研究提供了从系统识别(SI)角度优化构建模型的最少研究。本研究使用具有外源输入的非线性自回归模型(NARX)来表示pH-水的中和行为。该项目从输入和输出数据采集开始,导致NARX模型的开发。然后通过分析模型拟合和残差分布来评估模型性能。

The current global scenario is characterized by epidemics and various types of disasters, severely impacting communities' health, living conditions, and economic stability. Especially during such crises, the requirement for essential necessities becomes critical. Existing solution guidelines involve receiving donated items from public agencies through an offline system to provide assistance to victims. However, this implementation faces several limitations, such as a lack of understanding of people's needs in specific areas, leading to mismatches between assistance and actual requirements. Additionally, donators lack adequate information, resulting in further discrepancies between donated items and the victims' genuine needs. The available geospatial platforms primarily support surveillance and monitoring of epidemic or disaster situations but fail to address the management of needs related to donation and receipt. Through an extensive review of the literature and related research, it was identified that a geospatial platform specifically dedicated to donation management has not yet been developed. To address this gap, this research proposes the creation of a novel geospatial platform using data analysis and visualization methods, complemented by the integration of geofencing technology. By employing such an approach, the geospatial platform will play a pivotal role in enhancing disaster and epidemic assistance. It will facilitate efficient data processing and visualization, overcoming the limitations faced by the current offline system. Emphasis will be placed on improving the management of needs concerning donation and receipt, thereby mitigating mismatches between assistance and actual requirements. Consequently, this platform is expected to significantly enhance the effectiveness and targeting of aid distribution during times of crises.
当前全球形势的特点是流行病和各种灾害,严重影响了社区的健康、生活条件和经济稳定。特别是在这种危机期间,对基本必需品的需求变得至关重要。现有的解决方案指南涉及通过离线系统接收公共机构捐赠的物品,以向受害者提供援助。然而,这种实施面临一些限制,例如缺乏对特定领域人民需求的了解,导致援助与实际需求之间的不匹配。此外,捐助者缺乏足够的信息,导致捐赠的物品与受害者的真正需要之间进一步存在差异。现有的地理空间平台主要支持对流行病或灾害情况的监测和监测,但无法处理与捐赠和接收有关的需要的管理。通过对文献和相关研究的广泛回顾,确定了专门用于捐赠管理的地理空间平台尚未开发。为了解决这一差距,本研究建议使用数据分析和可视化方法创建一个新的地理空间平台,并辅以地理围栏技术的集成。通过采用这种方法,地理空间平台将在加强灾害和流行病援助方面发挥关键作用。它将促进高效的数据处理和可视化,克服当前离线系统面临的局限性。重点将放在改进对捐赠和接收方面需要的管理,从而减少援助与实际需要之间的不匹配。因此,预计这一平台将大大提高危机期间援助分发的有效性和针对性。

Ulayat land is traditional West Sumatra land frequently subject to competing demands from various stakeholders, including government agencies, private companies, and local communities. Those demands lead to the need to update geospatial data in the form of land use modeling for further land management purposes. This research used remote sensing technology to develop land use and land cover models based on cellular automata and socio-economic data. This research shows that there will be a significant increase in population in 2030, followed by changes in residential land use. The land use model shows that the use of customary land in most areas is not followed by a change in ownership which shows that tribe rules are still being followed and maintained correctly.
Ulayat土地是传统的西苏门答腊土地,经常受到包括政府机构、私营公司和当地社区在内的各种利益相关者的竞争需求。这些需求导致需要以土地利用建模的形式更新地理空间数据,以实现进一步的土地管理目的。这项研究利用遥感技术开发了基于细胞自动机和社会经济数据的土地利用和土地覆盖模型。这项研究表明,2030年人口将显著增加,随之而来的是居住用地的变化。土地使用模型表明,在大多数地区使用习惯土地后,所有权没有发生变化,这表明部落规则仍然得到正确遵守和维护。

This paper addresses the issue of environmental noise from mining operations, focusing on the specific case of a quarry located in the municipality of Trebejov, Slovakia. The study aims to demonstrate an effective approach to reducing noise pollution through the implementation of mobile noise barriers. The research was motivated by the negative impact of noise from the processing line on the well-being of the population residing in the vicinity of the facility. The study involved conducting extensive noise measurements at various locations surrounding the quarry. The collected data were analyzed to assess the existing noise levels and identify the areas of highest noise exposure. Based on the findings, the implementation of mobile noise barriers was proposed as a solution. The results of the study demonstrated that the mobile noise barriers successfully reduced the noise levels below the legal limits, significantly improving the well-being of the population living near the quarry. The case study opens up the possibility of using mobile noise barriers in other areas and operations with high noise exposure.

Radiological diagnostics are undeniably crucial in everyday healthcare. CT scans can sometimes provide misleading clues and delay successive treatment due to artifacts caused by reflected radiation from metallic implants. This work successfully segments multiple organs containing metal implants and discards artifacts using a combination of non-rigid transformations, Scribbles-based segmentation, and a pre-trained auto segmentation model (DynaUnet -Pretrained-Model). The presented transfer learning model combined the benefits of an interactive environment and reduced computational and processing-time costs. The transfer learning model proved high auto segmentation performance for multi-organs with metal implants' presence by decreasing metal artefact's impact on the segmentation process and the achieved segmentation accuracies between 0.9998 for the spleen and 0.9829 for the stomach.
不可否认,放射诊断在日常医疗保健中至关重要。CT扫描有时会提供误导性的线索,并由于金属植入物反射辐射引起的伪影而延迟后续治疗。这项工作成功地分割了包含金属植入物的多个器官,并使用非刚性转换、基于scribbles的分割和预训练的自动分割模型(DynaUnet -Pretrained-Model)的组合来丢弃人工制品。所提出的迁移学习模型结合了交互环境的优点,并减少了计算和处理时间成本。通过降低金属伪像对分割过程的影响,迁移学习模型对金属植入物存在的多器官具有较高的自动分割性能,脾脏和胃的分割准确率在0.9998和0.9829之间。

The monitoring performance of the photovoltaic system in real time is required for estimation and optimization purposes. This monitoring system has been the subject of extensive research, but in general it employs costly commercial software and as well as other license-based software. This paper discusses the design of a photovoltaic parameter monitoring system that uses Internet of Things technology to monitor in real time. This software is intended to be as interactive as possible in order to display all measurement data in the form of graphical according to a user-specified time interval. The constructed system is tested to display the measurement parameters of the fixed and dual axis solar tracker. The test results indicate that the system can display data in real time. Every data shown is accessible from any location and at any time, so long as the device being used is connected to the Internet. This system obviously can be applied and developed for an internet of thing-based photovoltaic parameter monitoring system to facilitate system estimation and optimization.

This system obviously can be applied and developed for an internet of thing-based photovoltaic parameter monitoring system to facilitate system estimation and optimization.","PeriodicalId":45439,"journal":{"name":"TEM Journal-Technology Education Management Informatics","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49388070","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}

This study proposes a novel approach to designing an integrated Resource Allocation and Task Allocation Optimization System (RATAOS) using Enterprise Architecture (EA) to improve project management efficiency. The proposed approach integrates Project Management Information System (PMIS) with an optimization system designed using a random forest model and Natural Language Programming (NLP). The integrated system optimizes resource and task allocation, reducing operational costs by 14% and planning phases by 88.7%. Project completion time increased by 50.80%, demonstrating the effectiveness of the integrated system. The purpose of this study is to find a solution for PMIS to be used as an automatic data-driven Resource and Task Allocation Optimization System. The technique used in this study is service integration between the existing PMIS with the Resource and Task Allocation Optimization System.

Establishing Cross-Curricular Connections Through Python Programming in Computer Modeling Education 在计算机建模教育中用Python编程建立跨学科联系
IF 0.7 Q4 COMPUTER SCIENCE, INFORMATION SYSTEMS Pub Date : 2023-08-28 DOI: 10.18421/tem123-61
T. Georgieva-Trifonova
In the present paper, the possibilities of making cross-curricular connections through Python programming in computer modeling education are explored. For this purpose, sample projects are systematized according to the study subjects – mathematics, history, geography, human and nature. Their designation is to contribute to the consolidation of certain knowledge and skills, both in terms of Python programming and in the relevant other subject. Concrete implemented projects are represented, different variants of them are discussed, and their accessibility is ensured for their future reuse for educational purposes. As a result, they could be directly used to apply a project-based teaching approach in learning relevant topics from the study material.
