Purpose: In general, most forklift accidents occur due to rollover. After a rollover, the first affected part is the driver's cabin, followed by the chassis and parts. In the study, cabin and chassis designs of diesel forklifts with increased driver safety and performance were made. Methodology:  Cabin and chassis tests were carried out with the Solid works program. According to the test results, the chassis and cabin design was made. Welding and assembly processes on the chassis of high-strength materials suitable for this design have been completed. Findings:  As a result of the studies, the cabin design, which is different from other similar forklifts, notches on the edges of the fender, the removal of fuel and oil tanks from the chassis, eliminating the leakage test, and the steps on the sides of the chassis being made monolithic, are important innovations. Unique contributor to theory, policy and practice:  As a result of all these studies, our KFD30 model was developed. This new model stands out with its new design and manufacturing on the forklift.

Purpose: Climate change (CC) caused by global warming has become a significant problem today.  Although Kenya has established several regulations and policies to deal with the impact of climate change and reduce its nationally determined contribution to near zero as committed in the Paris Agreement, there has been an increase in Co2 emissions, especially from the building industry. Therefore, this research aims to evaluate Kenya’s CC legal and regulatory framework, investigate challenges in Kenya’s CC regulatory policies, and propose practical strategies for the climate changepolicy challenges for Kenya’s building industry to reduce GHG emissions. Methodology: The researcher conducted thorough literature reviews. Secondary qualitative data was collected from government policy documents in various ministries, peer-reviewed papers, international treaties, and working papers from International Non-Governmental Organizations and extensively analyzed using a mixed data analysis strategy. Findings: Results from the analysis revealed that Kenya’s CC regulatory framework for the building industry is inadequate, not overarching, and has limited effects on practices and processes in the building industry, thus, the continued increase of GHG emissions. There are no specific industry policies to target their processes and practices, poor implementation and enforcement reduce the effectiveness of the policies, and inadequate funds lead to inept policies and inadequate skills. Unique contribution to theory, practice, and policy: The paper not only contributes Literary Knowledge to the subject area of climate change but also offers policy instruments that can be used as part of NCCAP to assist in CC policy formulation for the building industry.
目的:由全球变暖引起的气候变化(CC)已经成为当今一个重要的问题。尽管肯尼亚已经制定了一些法规和政策来应对气候变化的影响,并按照《巴黎协定》的承诺将其国家自主贡献减少到接近零,但二氧化碳排放量仍在增加,尤其是来自建筑行业的二氧化碳排放量。因此,本研究旨在评估肯尼亚的CC法律和监管框架,调查肯尼亚CC监管政策中的挑战,并为肯尼亚建筑业减少温室气体排放的气候变化政策挑战提出切实可行的策略。研究方法:研究者进行了全面的文献综述。从各部委的政府政策文件、同行评议论文、国际条约和国际非政府组织的工作文件中收集二级定性数据,并使用混合数据分析策略进行广泛分析。研究结果:分析结果显示,肯尼亚的建筑行业CC监管框架是不充分的,不是全面的,并且对建筑行业的实践和过程的影响有限,因此,温室气体排放的持续增加。没有特定的行业政策来针对他们的过程和实践,糟糕的实施和执行降低了政策的有效性,资金不足导致政策不有效和技能不足。对理论、实践和政策的独特贡献:本文不仅为气候变化主题领域贡献了文学知识,而且还提供了政策工具,可以作为NCCAP的一部分,协助建筑行业制定CC政策。

Purpose: In this research, a comparative analysis of the RSA and ELGAMAL algorithms is presented using their encryption and decryption speed with different key sizes. ElGamal and RSA are two popular public-key cryptographic algorithms that depend on the mathematical difficulty of computing discrete logarithms in finite fields and factoring large integers, respectively. Methodology: In this study, the speed at which messages of various sizes can be encrypted and decrypted using various key sizes is used to gauge how well these algorithms work. Findings: RSA usually outperforms ElGamal in terms of encryption and decryption speed, according to the results. However, as the key sizes grow, the performance gap between the two algorithms narrows. Unique Contribution to Theory, Policy and Practice: These findings can aid in selecting the appropriate algorithm and key size for different applications that require secure communication and data encryption.
目的:在本研究中,比较分析了RSA和ELGAMAL算法在不同密钥大小下的加密和解密速度。ElGamal和RSA是两种流行的公钥加密算法,它们分别依赖于在有限域中计算离散对数和分解大整数的数学难度。方法:在本研究中,使用不同密钥大小对不同大小的消息进行加密和解密的速度被用来衡量这些算法的工作效果。结果显示,RSA在加密和解密速度方面通常优于ElGamal。然而,随着密钥大小的增加,两种算法之间的性能差距会缩小。对理论、政策和实践的独特贡献:这些发现有助于为需要安全通信和数据加密的不同应用程序选择合适的算法和密钥大小。

Purpose: The most unsafe geological chance in steep places is landslides. Landslides in Ghana have long been a most important source of worry, mainly during the rainy season. In some highland settlements, most of the buildings in Kasoa are impacted because the community is situated on a landslide terrain.                                                                                        Methodology: In this project, cantilever and relieving platform retaining walls with varied heights of 3 to 10 meters and SBC 160 KN/m2 were analyzed and designed. Additionally, a comparative of factors like cost, efficiency, bending moment, stability against overturning, and sliding between the two retaining walls are shown. The cost comparison is done together with the comparative analysis, and the lowest or best estimate is selected.Findings: This research also demonstrated that the relieving platform retaining wall is less expensive, more stable, and relieves the heel portion's bending momentUnique Contributions to Theory, Policy and Practice: To reduce the risk of landslides on the road or in the town as a whole, we plan to construct or design a retaining wall model and, if possible, add a storm drainage system to the project.
用途:在陡峭的地方最不安全的地质机会是滑坡。长期以来,加纳的山体滑坡一直是人们最担心的问题,尤其是在雨季。在一些高地定居点,卡索的大多数建筑物受到影响,因为该社区位于滑坡地形上。方法:本项目对3 ~ 10米不同高度、SBC为160 KN/m2的悬臂式和卸荷平台挡土墙进行分析设计。此外,还比较了成本、效率、弯矩、抗倾覆稳定性和两个挡土墙之间的滑动等因素。成本比较与比较分析一起进行,并选择最低或最佳估算。研究发现:该研究还表明,减压平台挡土墙成本更低,更稳定,并减轻了脚跟部分的弯矩。理论、政策和实践的独特贡献:为了降低道路或城镇整体滑坡的风险,我们计划建造或设计挡土墙模型,如果可能的话,在项目中增加一个雨水排水系统。

Purpose: The introduction of the Public-Private-Partnership (PPP) in the delivery of low-cost houses in Congo is a recent phenomenon. The article will investigate the factors behind this new strategy of building affordable houses and try to establish how PPP can contribute to better housing for the residents of the most populated city of Congo (Kinshasa). The study focuses on the factors contributing to the increasing demand for the Public-Private-Partnership in the construction of affordable housing projects introduced by the Government. Methodology: For us to obtain the perspectives of key participants in the public sector dealing with the delivery of affordable housing projects in Kinshasa, an in-depth semi-structured interview and survey were conducted. This method combines qualitative and quantitative data collection techniques Findings: The result of the analysis shows that there are four main reasons for this increment: The lack of public resources, the high demand for low-cost housing, the Lack of qualified construction workers, and the lack of the private sector's interest to invest in social housing. Unique Contributions to Theory, Policy and Practice: The challenges of delivering low-cost house projects are numerous. The challenges are divided into different categories: political and economic, Governance, international forces, administration, financial resources, material resources, management practices, technical, and local external pressures, and natural forces are some of the issues that need to be addressed. While politics and governance, administration, financial and material resources, local external pressures, and environmental forces are all important, the performing organization faces external problems, as well as management and technical challenges.
目的:在刚果低成本住房的交付中引入公私合作伙伴关系(PPP)是一个最近的现象。本文将调查这一建设经济适用房的新战略背后的因素,并试图确定PPP如何为刚果人口最多的城市(金沙萨)的居民提供更好的住房。这项研究的重点是,在政府推行的可负担房屋项目中,公营部门与私营部门合作的需求日益增加,其中的因素。方法:为了获得金沙萨负责经济适用房项目交付的公共部门主要参与者的观点,我们进行了深入的半结构化访谈和调查。分析结果表明,造成这一增量的主要原因有四个:公共资源缺乏、对低成本住房的高需求、缺乏合格的建筑工人以及私营部门缺乏投资社会住房的兴趣。对理论、政策和实践的独特贡献:交付低成本住宅项目的挑战很多。这些挑战被分为不同的类别:政治和经济、治理、国际力量、行政、财政资源、物质资源、管理实践、技术和当地的外部压力以及自然力量是需要解决的一些问题。虽然政治和治理、行政管理、财政和物质资源、当地外部压力和环境力量都很重要,但执行组织面临外部问题,以及管理和技术挑战。

Purpose:  No matter how superior the techniques employed are, it’s only through positive attitudes of teachers that the benefits of computer integration into the curriculum instruction could be realized. The overall objective of this study was to examine influence of computer aided learning for teacher and students in promoting assimilation of knowledge. Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps. Findings: The study concluded that all the teachers and majority of the students (93.2%) disagreed to the statement that they had never used a computer and that they were not interested. Based on teachers’ perceptions towards the use of computer aided learning all the teachers’ strongly disagreed to the statement that computers scare them. Analysis of results showed that the teachers had a positive attitude towards computer aided learning. They therefore agreed that they believed computers were important teaching tool. The study also concluded that he school boards of management were partly involved in the training of teachers on computer aided learning and that the ministry of education also organized training courses for teachers on computer aided learning. Unique Contribution to Theory, Policy and Practice: The study suggests that parents associations (PA) in schools should develop a PA fund and organize equipping schools with more computers and other computer aided learning resources in order to make teaching and learning using computer aided learning easier. The current study suggests that there is need to organize in-service training for teachers in order to equip them with expertise skills and knowledge and build their confidence with ICT tools.
目的:无论采用多么先进的技术,只有通过教师积极的态度,才能实现计算机融入课程教学的好处。本研究的总体目的是探讨电脑辅助学习对教师和学生促进知识同化的影响。研究方法:本文采用桌面研究回顾方法,对相关的实证文献进行回顾,以确定主题并提取知识空白。调查结果:研究得出的结论是,所有教师和大多数学生(93.2%)不同意他们从未使用过电脑的说法,他们对电脑不感兴趣。基于教师对使用计算机辅助学习的看法,所有教师都强烈反对计算机使他们害怕的说法。结果分析表明,教师对计算机辅助学习持积极态度。因此,他们一致认为计算机是重要的教学工具。该研究还得出结论,学校管理委员会部分参与了对教师的计算机辅助学习培训,教育部也为教师组织了计算机辅助学习培训课程。对理论、政策和实践的独特贡献:研究建议学校家长协会应设立家长协会基金,并组织学校配备更多的电脑和其他电脑辅助学习资源,以使使用电脑辅助学习的教与学更容易。目前的研究表明,有必要为教师组织在职培训,以使他们具备专业技能和知识,并建立他们对ICT工具的信心。

The study also concluded that he school boards of management were partly involved in the training of teachers on computer aided learning and that the ministry of education also organized training courses for teachers on computer aided learning. \u0000Unique Contribution to Theory, Policy and Practice: The study suggests that parents associations (PA) in schools should develop a PA fund and organize equipping schools with more computers and other computer aided learning resources in order to make teaching and learning using computer aided learning easier. The current study suggests that there is need to organize in-service training for teachers in order to equip them with expertise skills and knowledge and build their confidence with ICT tools.","PeriodicalId":198033,"journal":{"name":"International Journal of Computing and Engineering","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122102384","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}

Cet article se propose d’examiner les niveaux de connaissance des mots et termes techniques en langue TSHILUBA KASAI ORIENTAL par les étudiants de l’architecture, de bâtiments et des Travaux Publics et par les personnes intellectuellement indiscriminés du milieu. En effet cette connaissance en sa langue propre, surtout maternelle, facilitera sans doute l’usage correcte de chaque mot ou terme lors de la construction ou de réalisation des diverses œuvres d’arts.
本文旨在考察建筑、建筑和公共工程专业的学生以及该领域的智力不分青红皂白的人对东开赛齐卢巴语词汇和技术术语的知识水平。事实上,这种母语知识,特别是母语知识,无疑将有助于在建造或制作各种艺术作品时正确使用每个单词或术语。

Purpose: The purpose of this study was to establish the influence of internet use on socialization among undergraduate students of University of NairobiMethodology: The study adopted a descriptive survey design. The accessible population of the study was 15, 000 from main campus. Data was collected from a sample of 384 students from the university via use of questionnaire and an interview guide as data collection tools which contained both closed and open ended questions and encouraged the respondents to participate due to anonymity. The data collected was analyzed by use of descriptive statistics. In particular excel SPSS and frequency tables were used.Results: The study findings indicated that internet use may not have a negative effect on socialization as indicated in literature. The findings uphold that internet users spend more time socializing with friends when compared to non-users. The forms of internet mostly used by University of Nairobi students are internet enabled cell phones followed by computer labs and cyber cafes. Internet enabled cell phones were preferred because of the portability, convenience and cost while computer labs was preferred because of accessibility and the fact that they are free. The social sites mostly used by both the undergraduate students were Facebook, electronic mail, yahoo messenger, twitter and Skype.Unique contribution to theory, practice and policy: The study recommended that since university of Nairobi undergraduates are frequent users of the internet, the university should increase the number of computers in the computer lab. It was also recommended that the university should exploit this avenue and ensure that more educational content are passed onto the students through the internet. This will pave way for e-learning. The university may use social media to reach the students as a part of a whistle blower policy where anonymous comments are posted, blogs and contributions on a certain issue can also be posted.
摘要目的:本研究旨在探讨网路使用对奈洛比大学本科生社交的影响。方法:采用描述性调查设计。该研究的可接触人群是来自主校区的15,000人。通过问卷调查和访谈指南作为数据收集工具,对该校384名学生进行了数据收集,问卷调查和访谈指南包含封闭式和开放式问题,并鼓励受访者匿名参与。收集的数据用描述性统计进行分析。特别使用了excel、SPSS和频率表。结果:研究结果表明,网络使用可能不会像文献所述的那样对社交产生负面影响。研究结果表明,与不上网的人相比,上网的人花更多的时间与朋友交往。奈洛比大学学生最常使用的网络形式是可上网的手机,其次是电脑实验室和网吧。能上网的手机因为便携、方便和便宜而更受欢迎,而计算机实验室则因为可访问性和免费而更受欢迎。这两名大学生使用最多的社交网站是Facebook、电子邮件、雅虎即时通讯、twitter和Skype。对理论、实践和政策的独特贡献:该研究建议,由于内罗毕大学的本科生经常使用互联网,大学应该增加计算机实验室的计算机数量。还有人建议大学应该利用这一途径,确保通过互联网将更多的教育内容传递给学生。这将为电子学习铺平道路。作为告密者政策的一部分,大学可能会使用社交媒体来联系学生,其中匿名评论可以发布,关于某个问题的博客和贡献也可以发布。
