This paper presents the results of research on the technical–economic optimization of FDM parameters (Lh—layer height and Id—infill density percentage) for the manufacture of tensile and compression samples from recycled materials (r) of PETG (polyethylene terephthalate glycol) and ASA (acrylonitrile styrene acrylate) in the context of the transition to a circular economy. To carry out our technical–economic study, the fundamental principle of value analysis was used, which consists of maximizing the ratio between Vi and Cp, where Vi represents the mechanical characteristic (tensile strength or compressive strength) and Cp represents the production cost. The results of this study showed that, in the case of tensile samples manufactured by recycled PETG (rPETG), the parameter that significantly influences the results of the Vi/Cp ratios is Lh (the height of the layer), while for the samples manufactured additively from recycled ASA (rASA), the parameter that decisively influences the tensile strength is Id (the infill density percentage). In the case of compression samples manufactured by FDM from recycled PETG (rPETG) and recycled ASA (rASA), the parameter that signified influences the results of the Vi/Cp ratios is Id (the infill density percentage). Following the optimization of the FDM parameters, using multiple-response optimization, we identified the optimal parameters for the manufacture of parts by FDM from rPETG and rASA: Lh = 0.20 mm and Id = 100%. The results of this study demonstrated that the use of recycled plastics from PETG and ASA lends itself to a production and consumption model based on a circular economy. [ABSTRACT FROM AUTHOR]

City parks are of great importance to people living in cities, and the presence of trees in the parks increases the value of the parks. There are many types of trees that can be planted in parks. However, it is not possible for every tree to adapt to every natural environment. In addition, the initial investment costs of the trees, the characteristics that may affect the life cycle costs, and the expectations of managers and park users from the trees also affect this choice. All these criteria should be evaluated together, and the ideal selection should be made. Value Engineering is a method that can be applied to make the most appropriate choice by taking into account the wishes of all stakeholders. Value engineering (DM) can be defined as an organized effort to analyze product features, functions and material selections; is designed to solve problems and/or reduce costs while maintaining or improving performance and quality requirements; and performs essential functions at the required quality, reliability, and life-cycle cost. In this study firstly a value engineering team was formed. The value engineering team decided that the trees should be coniferous with the prerequisite that they can remain green without shedding their summer-winter leaves and determined which criteria the coniferous trees required to be located in the park should meet. The team members conducted value engineering after determining which trees met these criteria and were subsequently purchased. In this study, since an existing project and a new project are not compared, it does not include a result on how much the cost gain is. As a result, the team determined the most appropriate optimum cost solution with the value engineering method to meet all the criteria among the determined alternative tree species.

Abstract Objective This study aims to assess the significance of monitoring temperature change trends at various wound sites in the healing process of diabetic foot ulcers after microcirculation reconstruction surgery. Methods A retrospective analysis was conducted on individuals with diabetic foot ulcers who had been admitted to the Department of Orthopedics at the Second Hospital of Shanxi Medical University between July 2020 and February 2022. Temperature changes were regularly monitored at the center of the wound and the distal tibia of the ipsilateral lower leg to assess microcirculatory blood perfusion. Wound, ischemia, and foot infection (WIFi) grading was performed at admission and the final follow-up was to determine the value of temperature monitoring at various sites. Additionally, the formation of collateral microarterial vessels was monitored to determine their consistency with the observed trends in temperature differences. Follow-up assessments included the recurrence of ulcers, development of ulcers at different locations, re-amputation of the toe or limb, and diabetes-related mortality. Results A total of 29 patients were included in the follow-up, with an average age of 57.14 ± 14.75 years and a follow-up period of 9.79 ± 4.13 months. Following microcirculation reconstruction surgery, as the microvascular network formed, the temperature difference between the center of the wound and the distal tibia on the same side gradually decreased, with no statistical difference observed at 4 weeks postoperatively. At both admission and the final follow-up, there was a significant reduction in the wound (W) and ischemia (I) grades within the WIFi classification. The temperature at the wound center showed progressive improvement as collateral microarterial vessels developed. During the follow-up period, there were 2 cases of ulcer recurrence, 1 case of an ulcer appearing at a different location, no cases of re-amputation of the toe or limb, and 2 diabetes-related fatalities. Conclusion Skin temperature monitoring offers a direct and reliable indication of microcirculatory blood perfusion. Its simplicity and cost-effectiveness make it a valuable tool for widespread use in evaluating wound healing following microcirculation reconstruction surgery.

Time-consuming ocean transportation for international trades requires enterprises to advance payments for goods, which can be fatal for small and medium enterprises with insufficient self-owned capital. Logistics finance is an effective solution for tackling this problem. However, traditional logistics finance has long been plagued by information asymmetry, tremendous paperwork, and long financing cycles. As a distributed database with characteristics of transparency, traceability, and immutability, blockchain technology shows good potential in addressing pain points on traditional logistics financing platforms. This paper focuses on the operational mechanism and value analysis of the blockchain-based port logistics finance platform. The conceptual architecture of the blockchain-based port logistics finance platform is constructed, and a value analysis model based on the Newsboy Model is established for quantitatively analysing the platform's value. The results revealed that the introduction of the blockchain into port logistics financing can significantly improve small to medium-sized enterprises' profitability by providing reliable financing channels. The results also indicate that participants' profit on the blockchain-based platform may be influenced by the speed of market expansion, initial capital size, and financing cost. This paper also discusses theoretical and managerial implications by providing insights into the participants' decision-making on the platform under different constraints. [ABSTRACT FROM AUTHOR]

Legal research methods refer to a general term for disciplined and systematic procedures, approaches, means, techniques, and models used by researchers to acquire novel and reliable legal knowledge. Several theoretical debates on the originality of legal research methods go on as follows: Is one legal research method superior to another? Do legal research methods aim for methodological independence? Are legal research methods objective or subjective? Influenced by scientism, positivism is usually considered to be the only reasonable research method, but since law is different from science, only using positivist research approaches is insufficient for solving legal problems. Strictly speaking, a method that is appropriate for the research subject is a reasonable method. As one of the humanities and social sciences, law has similarities with other disciplines in terms of the scope of research; therefore, its research methods could be borrowed from other disciplines. However, law cannot ignore the development of its own unique research methods while retaining its advantages. Legal research methods are supposed to be objective because they should follow scientific standards and have objective arguments, but inevitably, legal research would be subjective and full of value judgments since it means subjective and creative activities of researchers. Of course, the choice of values should preferably be made in the context of value-freeness to ensure the organic combination of value-freeness and value judgment. [ABSTRACT FROM AUTHOR]

The article presents the results of the technical–economical study regarding the optimization of fused deposition modeling (FDM) parameters (the height of the layer deposited in one pass—Lh and the filling percentage—Id) for the manufacture of Polyethylene Terephthalate Glycol (PETG) and Acrylonitrile Styrene Acrylate (ASA) parts. To carry out this technical–economical study, was used the fundamental principle of value analysis, which consists of maximizing the ratio between Vi and Cp, where Vi represents the mechanical characteristic, and Cp represents the production cost. The results of the study show that for tensile specimens made of PETG, the parameter that significantly influences the results of the Vi/Cp ratios is the height of the layer deposited in one pass, (Lh), and in the case of the compression specimens made of PETG, the parameter that significantly influences the results of the Vi/Cp ratios is filling percentage (Id). In the case of specimens manufactured via FDM from ASA, the parameter that decisively influences the results of the Vi/Cp ratios of the tensile and compression specimens is the filling percentage (Id). By performing optimization of the process parameters with multiple responses, we identified the optimal parameters for FDM manufacturing of parts from PETG and ASA: the height of the layer deposited in one pass, Lh = 0.20 mm, and the filling percentage, Id = 100%.

Millions of users nowadays rely on their smartphones to process sensitive data through apps from various vendors and sources. Therefore, it is vital to assess these apps for security vulnerabilities and privacy violations. Information such as to which server an app connects through which protocol, and which algorithm it applies for encryption, are usually encoded as variable values and arguments of API calls. However, extracting these values from an app is not trivial. The source code of an app is usually not available, and manual reverse engineering is cumbersome with binary sizes in the tens of megabytes. Current automated tools, however, cannot retrieve values that are computed at runtime through complex transformations. In this article, we present ValDroid, a novel static analysis tool for automatically extracting the set of possible values for a given variable at a given statement in the Dalvik byte code of an Android app. We evaluate ValDroid against existing approaches (JSA, Violist, DroidRA, Harvester, BlueSeal, StringHound, IC3, and COAL) on benchmarks and 794 real-world apps. ValDroid greatly outperforms existing tools. It provides an average F1 score of more than 90%, while only requiring 0.1 s per value on average. For many data types including Network Connections and Dynamic Code Loading, its recall is more than twice the recall of the best existing approaches. [ABSTRACT FROM AUTHOR]

Several developing countries around the globe have launched their future visions, which include concrete strategic plans that involve many kinds of mega-construction projects. One common goal across these visions is to increase the efficiency of construction projects' huge expenditures using recent sustainable, practical engineering tools, such as the value engineering (VE) approach. Although the VE approach has been around for a few years now, some barriers prevent the popularity of its application in different construction projects. This research investigates the barriers to adopting VE through a systematic literature review. This study has categorized the application barriers using thematic analysis under three main categories: barriers related to practitioners' knowledge and background, barriers associated with the behavior of practitioners towards VE, and barriers related to the implementation of VE. Moreover, this research has investigated solutions to overcome these barriers and improve the application of VE in construction projects. Saudi Arabia's construction industry is used as a case study. A survey was distributed to Saudi construction industry practitioners using the snowballing technique to evaluate the criticality of the found barriers to adopting VE and the best strategic solutions to overcome these barriers using the importance–performance analysis (IPA) approach. Based on the results of this study we have specifically recommended including a VE course in college engineering programs and an incentive clause in construction contracts to encourage VE application on construction projects at the top of the list of proposed solutions. Finally, defining the criticality of barriers and the effectiveness of solutions will help enhance the application of VE and sustainability practices in the Saudi Arabian construction industry and around the globe.

Cost analysis is a method to enhance the costs efficiency by evaluating the corporate profitability. In today business environment of global competition, war pressures, new markets and demographics, firms are changing their approach to cost control. In fact, the strategic cost analysis provides useful information for the short and long-term decision-making in order to achieve the growth corporate goals. In the current phase of global competition (Global Shortage Management) corporations must adapt their strategic cost analysis (Value Analysis, Value Engineering or Value Management) to specific competitive policies adopted in certain markets, which may concern 'Planned Obsolescence', 'Total Quality Management (TQM)' or 'Zero Defects Productions' objectives

In the context of sustainable development and continuous improvement, it can be stated that the implementation of an integrated quality management in a modern organization can only be achieved under the conditions of implementing a series of concepts, among which we can mention knowledge management, total quality management, Kaizen management and related standards, quality management strategies and policies but also quality management techniques, methods, and tools. The scientific paper presents an own point of view regarding the pathway for a sustainable implementation of the previously presented concepts in an organization in the automotive field. The aspects identified in a real organization in the automotive industry are presented as well as the way considered to be possible to implement so that the organization can be considered a knowledge-based organization. In this context, the role of management in the organization is extremely important and value analysis becomes a priority. The main objective of the scientific paper is to propose a certain way of managerial thinking so that those interested can apply the quality management strategies and policies proposed for the sustainable implementation of total quality management within an organization based on knowledge in the automotive field.

The paper brings forward the results of a study on the compression test of 28 lattice structures made of PLA by FDM, with the height of the deposited layer at a pass of Hs = 0.20 mm and 50% filling percentage Pu. The 28 samples were made on Anycubic 4 Max Pro 2.0 the 3D printer, considering 7 filling patterns: Grid, Tri-hexagon, Octet, Triangles, Cubic subdivision, Gyroid, and Cross 3D for each type of lattice structure. The dimensions of the specimens, before and after the compression test, were determined using the DeMeet 3D coordinate measuring machine. In this context, a minimum printing accuracy value of 98.98% and a maximum deformation value of 57.70% were recorded for the lattice structure corresponding to the Triangles fill pattern. For the same Triangles type lattice structure, the highest average maximum compressive force of 87.32 kN was obtained. The maximization of the ratio between the use value and the production cost, one of the fundamental technical-economic principles of value analysis, was obtained for the lattice structure corresponding to the Cubic subdivision filling model.

This paper presents a technical-economical optimization by maximizing the ratio between the critical buckling pressure (technical characteristic) and the production cost (economic characteristic) of stiffened cylindrical shells, a basic concept of value analysis. Critical buckling load values were determined using both the Finite Element Method (FEM) and analytical calculations to validate the accuracy of the results obtained. The maximum difference between the analytical and numerical results was 10%. Technicaleconomic optimization was carried out using the design of experiments method with MINITAB 19 and allowed to select the optimal input parameters, stiffener dimensional ratio 0.10, shell wall thickness 2.50 mm, and distance between circumferential stiffeners 400 mm, and identify the main factors that impact the output response. For the optimal constructive configuration, the ratio between the critical buckling load and the production cost of the stiffened cylindrical shells was maximized by 199%. [ABSTRACT FROM AUTHOR]

This research aims to develop discrete fundamental theorems using a new strategy, known as delta integration method, on a class of delta integrable functions. The ν th-fractional sum of a function f has two forms; closed form and summation form. Most authors in the previous literature focused on the summation form rather than developing the closed-form solutions, which is to say that they were more concerned with the summation form. However, finding a solution in a closed form requires less time than in a summation form. This inspires us to develop a new approach, which helps us to find the closed form related to nth-sum for a class of delta integrable functions, that is, functions with both discrete integration and nth-sum. By equating these two forms of delta integrable functions, we arrive at several identities (known as discrete fundamental theorems). Also, by introducing ∞-order delta integrable functions, the discrete integration related to the ν th-fractional sum of f can be obtained by applying Newton's formula. In addition, this concept is extended to h-delta integration and its sum. Our findings are validated via numerical examples. This method will be used to accelerate computer-processing speeds in comparison to summation forms. Finally, our findings are analyzed with outcomes provided of diagrams for geometric, polynomial and falling factorial functions. [ABSTRACT FROM AUTHOR]

This article introduces a multi-objective optimization approach for determining the best 3D printing parameters (layer thickness and infill percentage) to efficiently produce PLA and ABS parts, extensively analyzing mechanical behavior under tests for different traits such as tensile strength, compression, flexural, impact, and hardness. The value analysis method is used to optimize settings that balance use value (Vi- represented by mechanical characteristics) and production cost (Cp). Findings reveal that the infill percentage significantly influences the Vi/Cp ratio for tensile, compression, and hardness tests, while flexural tests are influenced by layer thickness. Impact strength is influenced nearly equally by both factors, with material-specific variations. The desirability function proved useful for optimizing processes with multiple responses, identifying the optimal parameters for the FDM process: a layer thickness of 0.15 mm with 100% infill percentage for PLA, a layer thickness of 0.20 mm with 100% infill percentage for annealed PLA, and a layer thickness of 0.15 mm with 100% infill percentage for ABS. Overall, this study guides efficient 3D printing parameter selection through a technical-economic optimization based on value analysis. [ABSTRACT FROM AUTHOR]

Factors such as the rapid depletion of natural resources and environmental pollution enable us to better understand the importance of the concept of sustainability today. With the introduction of the concept of sustainability into the construction sector, the design of buildings according to the environmentally friendly "Green Building" approach has come to the forefront, and various certification systems have been developed. Due to these certification systems, various building materials are required to be used in buildings. However, since there are many materials on the market, it is a problem as to which of these materials should we prefer according to the green building criteria. Although there are various approaches in this regard, the value engineering method is an ideal method because it takes into account both the criteria that the materials must meet as well as their costs. Value Engineering is the teamwork carried out to analyze the building properties, systems, equipment, and material selections, while considering the costs, in order to perform the necessary performance, quality, reliability, and basic functions. In this article, a method on how to choose a value-based, sustainable material was proposed, and as a case study, a product that can be used as an exterior cladding material of a building using LEED criteria, which is used for providing certification for sustainable green buildings, was selected. Initially, a value engineering team was formed. This team determined the qualities that the product should have based on LEED criteria and the eight different material alternatives that can meet these qualities. Subsequently, value analysis was conducted, and the highest value exterior coating material was determined.

Multiple policies have been formulated to promote the development of prefabricated building (PB). However, ineffective policies increase the financial burden of the governments and hinder PB development. This study aims to identify effective policies and develop a practical policy framework to encourage developers to implement PB. Text analysis is to identify the policies related to PBs from the numerous samples. A survey is to verify the effective policies and explore their effects on the developers' willingness to implement PBs. The findings suggest that the current policy system of PBs is complete but uneven, focusing on environmental policies. The most cost-effective tools are land limitations, tax incentives, and financial support. Besides, policies are interrelated in affecting developers' willingness to implement PBs. It provides a reference for policy evaluation in application scenarios, which expands the literature research on the policy. Meanwhile, it provides a guide for policymakers to evaluate the effectiveness of policies and formulate practical policy frameworks to promote PB development. [ABSTRACT FROM AUTHOR]

The global concrete and construction industry's growth has led to a shift in priorities, with a greater emphasis placed on sustainability. Hence, with technological advances, the concrete industry seeks additional cementitious materials to produce value-added products. By emphasizing the financial, ecological, and technological benefits of using fly ash as a partial cement replacement, the study constructed a framework which integrates the economic, environmental, and social pillars of sustainability through value engineering. Experimental results from 42 previous studies are analyzed and presented to underline the unique characteristics of fly ash concrete alternatives across five criteria (replacement, strength gain, compressive strength, slump, and permeability), showing how they differ from conventional concrete, and how they can be used to implement sustainable practices with positive financial outcomes. This study showed that the alternatives' value gradually increases up to two times at 50% cement replacement. On the other hand, while the construction cost gradually increased to a peak of 19.69%, the life cycle cost went down by 41.45% at the same percentage. Thus, customers can emphasize the superiority of eco-friendly concrete while also highlighting the economic benefits, making it a more competitive option for them and expanding its market.

At present moment, the processes of digitalization and informatization of all spheres of human life and society are rapidly gaining momentum. Of course, many factors influence them. Nevertheless, they are based on the development of the hardware (technical) component along with the development and implementation of software. The rapid growth of information and communication technologies (ICT), as well as the development of the digital economy and e-business, in turn led to an increase of the employees in this sector in the national economies across the world. Particular attention should be paid to the problems of organizing business processes in companies operating in the field of information technology (IT), as well as the economic justification of managerial decisions and evaluation of their effectiveness. To date, the science and practice of management has developed a set of theoretical and methodological approaches to solving the above problems, which, of course, can be successfully used in the practice of managing IT companies. It is known that the management of IT companies uses the well-proven tools of lean manufacturing, 6 sigma, Gantt charts, Ishikawa charts, etc. At the same time, there are a number of techniques (for example, functional cost analysis (or value analysis, VA)) that have not received proper distribution in IT-companies, despite the fact that they have serious potential for conducting a feasibility study. This article attempts to review the history of the creation and development of the VA in the USA and the USSR. Further, on the one hand, the possibilities of using such a tool as the VA in the management of IT companies are shown, and, on the other hand, due to the current terminological inconsistencies, the legitimacy of using the conceptual and categorical apparatus, which belongs to the subject area of the VA, is analyzed. We are talking about the following terms: “functional-cost analysis”, “cost analysis”, “elemental analysis”, “cost engineering”, “cost management”. The results of the study allow us to state the expediency of using the VA tools in the development of software products.
