Design thinking is an innovative way of thinking and solving problems in which the focus is on the user. This paper provides an overview of current research on the topic to gain insight into current practices and create a basis for further development of the area. Synthesis of knowledge is presented through historical development, methodology, and processes used in the field. The methodology used is a desk-research method through which a comparison of the literature was conducted. According to the results of the research, we can conclude that there is still no harmonized definition of design thinking. Therefore, due to the rapid development of this field, it is necessary to synthesize the latest research. Also, it is important to provide expert designers with specialized books and tools since the problems are becoming more complex, and designers with competencies required to solve such problems are needed.

Starting from the general concept of a system-process, which is defined by the quality of relations between individual elements, we can single out attributes whose elements have a dominant character of the information system, all in the projection of the quality of the observed process. In any state of the process, information is undoubtedly significant as a subsystem, whose property cannot be ignored, because it is a dynamic process that bases its dynamism in the time domain. The paper precisely defines the information power model as well as its response to the occurrence of perturbations in a strictly defined time domain, all in the function of one process-event. The described complexity can be a function of horizontal complexity, whereby a hierarchical component is frequently lost, or it can be another component resulting from the overall information process. The paper deals with measurements of the response to an event that took place at the global level, that is, the finals of the UEFA Champions League 2021. A unique functional relationship of power of information in strictly defined marginal conditions was obtained. The paper presents the spectrum of the power of occurrence-opening of the portal of the mentioned event through the functional relationship of the dynamic process. All the described phenomena gave new insights in the development of the information model.
从系统过程的一般概念出发,系统过程是由单个元素之间的关系质量定义的,我们可以挑出那些元素在信息系统中具有主导特征的属性,所有这些都是在观察过程质量的投影中。在过程的任何状态下,信息无疑是一个重要的子系统,其性质不容忽视,因为它是一个动态过程,其动态性建立在时域上。本文精确地定义了信息功率模型及其在严格定义的时域内对扰动发生的响应,所有这些都是一个过程事件的函数。所描述的复杂性可以是水平复杂性的函数,其中层次组件经常丢失,或者它可以是由整体信息处理产生的另一个组件。本文讨论了对发生在全球层面的事件的反应的测量,即2021年欧洲冠军联赛决赛。在严格定义的边际条件下,得到了唯一的信息幂函数关系。本文通过动态过程的函数关系,给出了上述事件发生-打开门的能力谱。所有描述的现象都为信息模型的开发提供了新的见解。

The objective of this research is to study the free vibration of a cantilever Euler-Bernoulli beam carrying a point mass with moment of inertia at the free end using the spectral element method (SEM). Typically, the shape (or interpolation) functions used in the Spectral element method are derived from exact solutions of the governing differential equations of motion in the frequency domain. The beam was discretized by a single spectral element which was connected by a point mass at the free end. The dynamic stiffness matrix of the beam is formulated in frequency domain by considering compatibility conditions at the additional mass position. Then, the first three natural frequencies of the cantilever beam are determined. After the validation of the spectral element method, the influence of the non-dimensional mass parameter and the non-dimensional mass moment of inertia on the first three natural frequencies and shape mode are examined.

Playground is effective on behavior of children; however, the severity of this effect and its variety in different playgrounds is still unclear. Identifying the playing area, reviewing local observations, evaluating interactions and their extent, and analyzing the level of communication between children can lead to correct ranking of playgrounds. Features of playground and the created space along with vegetation and plants are effective factors in attracting children and encouraging them to increase interactions. Various features of playground can determine the extent to which a child participates in social interactions. These features, along with other environmental factors, allow the development of social behaviors for children. Therefore, playgrounds must have potential facilities and capabilities for influencing children to provide high quality. This study will analyze the Pasdaran Park playground using quantitative method and distributing questionnaires. Field study is required to obtain the results. To this end, a questionnaire containing 18 questions was developed using parameters and factors previously defined and scored on a 5-point Likert scale. Fifty park visitors were questioned. According to the results, the most important factors, which can increase satisfaction and meet visitor needs include providing new access routes and improving the existing ones, increasing children interactions in green spaces, using vegetation in the environment, improving the environment according to the needs of users. The results of this study can be used as guideline for designing and developing this space and similar spaces.
游乐场对儿童行为的影响;然而,这种影响的严重程度及其在不同操场上的多样性仍不清楚。确定游戏区域,回顾当地观察,评估互动及其程度,并分析儿童之间的交流水平,可以导致游乐场的正确排名。操场的特点和创造的空间以及植被和植物是吸引儿童并鼓励他们增加互动的有效因素。操场的各种特征可以决定孩子参与社会互动的程度。这些特征和其他环境因素共同决定了儿童社会行为的发展。因此,游乐场必须具有影响儿童的潜在设施和能力,以提供高质量。本研究将采用定量分析的方法和问卷调查的方式对帕斯达然公园的游乐场进行分析。需要实地研究才能获得结果。为此,使用先前定义的参数和因素开发了包含18个问题的问卷,并以5分李克特量表评分。50名公园游客接受了调查。根据研究结果,提高满意度和满足游客需求的最重要因素包括提供新的通道和改善现有的通道,增加儿童在绿地中的互动,在环境中使用植被,根据用户的需求改善环境。研究结果可以作为该空间及类似空间的设计和开发的指导。

This research develops a three degrees of freedom (DOF) measurement system by integrating Fabry-Perot interferometer and photoelectronic inspection module to determine linear displacement, horizontal and vertical straightness geometric error parameters simultaneously. The interferometer and the photoelectronic inspection module in a three DOF measurement system share the same light source, and the two structures are used to measure linear displacement and straightness errors. The experimental results are utilized to calculate the relevant error parameters according to ISO standards and numerical analysis. They show that after the machine error compensation, the positioning deviation of the system is reduced from 55 μm to 19 μm, corresponding to the reduction of 65%. The accuracy is promoted from 65 μm to 31 μm, about the improvement of 52%. The horizontal and vertical straightness errors of the machine are 4.30 μm and 5.71 μm respectively.

The term “Business intelligence” is described as a plan or a strategy where the operations like reporting, data analysis, data mining, event processing are performed to improve the production and growth of a business enterprise or a business entity. And on the other hand, the “Knowledge management” is explained as well-organized management of resources and information within a commercial organization it can be a business too. Almost all business will have limitations and challenges which can be also known as the business problems. One of the main business problem is demand, the business plans must work according to the demand of the consumers. Analyzing the demand would provide the solutions for queries like what is the business trend? What is the need of the users? What should be the improvement make in the production? Where is the current position of the enterprise? And who all will be the competitors? For the predictive analysis a dataset of bitcoin is taken. The major aim of the study is to implement the strategies to overcome the business problems mainly the demand prediction. And the objective is to find out the relevant issues and the remedies by using knowledge management and business intelligence to the common business problems. The dataset has columns called lowest price, highest price, open price, close price, trading volume and market capital. The research methodology used is predictive analysis using PCA and K-means clustering algorithm. By this dataset predictive plots are developed as achieved results for easy analysis by using research methodology. PCA and K-means are the algorithm used for accurate prediction. The importance of study is to predict the future sale, as it is very essential for a business enterprise to find future demand so that the organization can improve production.
术语“商业智能”被描述为执行报告、数据分析、数据挖掘、事件处理等操作以改进业务企业或业务实体的生产和增长的计划或策略。另一方面,“知识管理”被解释为对商业组织内资源和信息的良好组织管理,它也可以是一个企业。几乎所有的业务都会有限制和挑战,这也被称为业务问题。一个主要的商业问题是需求,商业计划必须根据消费者的需求工作。分析需求将为诸如业务趋势是什么之类的查询提供解决方案?用户的需求是什么?在生产中应该做些什么改进?企业目前的位置在哪里?谁将成为竞争对手?为了进行预测分析,我们采用了比特币的数据集。研究的主要目的是实施战略,以克服业务问题,主要是需求预测。目的是通过知识管理和商业智能对常见的业务问题进行分析,找出相关的问题和补救措施。该数据集有最低价、最高价、开盘价、收盘价、交易量和市场资本等列。使用的研究方法是使用PCA和K-means聚类算法的预测分析。利用该数据集开发预测图作为已取得的结果,便于使用研究方法进行分析。PCA和K-means是用于准确预测的算法。研究的重要性是预测未来的销售,因为它是非常必要的一个企业发现未来的需求,以便组织可以提高生产。

In an era where global trade has developed along with the massive number and expansion of knowledge, the necessity of exchanging knowledge and international business has continuously increased. This is in light of international business organizations’ intellectual capital, which propels them into global competition and provides them with a competitive advantage if utilized properly. The purpose of this research is to examine and assess two topics, namely, knowledge sharing and international business, as well as their location in research studies, importance, definitions and histories of those terms, and research interests for each one of these two dimensions. The review focused on the topic of knowledge sharing in international business organizations, with analysis and discussion of the most important research, studies, and trends along three axes: knowledge sharing, international business organizations, and earlier studies. The study concluded that knowledge sharing is an essential aspect of knowledge management since it connects the previous processes of acquiring knowledge capital to the subsequent processes of application and practice, which is especially important for international business organizations that need to benefit from knowledge in a variety of ways. In addition to the scarcity of studies that coupled knowledge sharing and international business, there is a great scope for developing models and applications in this field of study. We were unable to find studies that combined the two themes through research, but they were implicitly addressed within the research to highlight the importance of knowledge sharing in international business, and this is what motivates more research in this field due to the shortcoming of studies on the subject. It seemed to be that the essential element to organizational innovation is knowledge development and sharing.
在全球贸易随着知识的大量增加和扩展而发展的时代,知识交流和国际商务的必要性不断增加。这是因为国际商业组织拥有智力资本,如果利用得当,智力资本将推动它们参与全球竞争,并为它们提供竞争优势。本研究的目的是检查和评估两个主题,即知识共享和国际商业,以及它们在研究中的位置,重要性,这些术语的定义和历史,以及这两个维度中每一个的研究兴趣。本综述以国际商业组织中的知识共享为主题,从知识共享、国际商业组织和早期研究三个方面对最重要的研究、研究和趋势进行了分析和讨论。研究得出结论,知识共享是知识管理的一个重要方面,因为它将先前获取知识资本的过程与随后的应用和实践过程联系起来,这对于需要以各种方式从知识中受益的国际商业组织尤为重要。除了缺乏将知识共享与国际商业相结合的研究之外,在这一研究领域中开发模型和应用还有很大的空间。我们无法通过研究找到将这两个主题结合起来的研究,但在研究中含蓄地强调了国际商业中知识共享的重要性,这是由于该主题研究的不足而促使该领域进行更多研究的原因。组织创新的基本要素似乎是知识的开发和共享。
