Private schools need help in handling school fees and financial processes. Traditional manual payment systems result in data processing issues, delayed financial reporting, and complications from misplaced records. Late fee payments threaten school income, which is crucial for staff salaries. Modern solutions are imperative. Desktop applications have limitations, requiring installation on specific devices, leading to compatibility concerns. This research opts for a web-based application. It employs prototyping models and predictive abilities using the Naïve Bayes algorithm. The web-based application aims to streamline fee management and predict payment delays, enhancing financial transaction management while prioritizing data security through database encryption. This web-based solution aligns with private schools' operational needs, simplifying payments and increasing late payment prediction accuracy. Extensive black-box testing validated its suitability, satisfying administrative staff needs. Four test cases gained administrative team approval. This innovation empowers private schools to optimize operations and financial management. In summary, the research tackles critical financial challenges private schools face by introducing a web-based application that simplifies payment processes, enhances accuracy in predicting late payments, and aligns seamlessly with administrative needs.

Prototyping is a core activity in developing new products, processes, and organisations alike. This paper describes the prototyping activities of 31 engineering design professionals in a high-technology industrial company, examining the distribution of different types of activities across different phases of development based on thematic interviews. Examining 62 prototyping and testing pathways, we found that most prototyping paths started with the practitioners’ own activities, which was also more likely to lead to paths with more prototyping steps than if the first prototyping activity took place with a stakeholder. Overall, the paths were short, indicating a lack of iteration. Both internal and external stakeholders were involved in collaborative prototyping. This collaboration was enabled by personal and unit level relationships, and different stakeholders were involved in different phases of development. Taken together, our results suggest that practitioner attention in prototyping may focus on latter development phases and demonstrate less iteration than what literature might suggest, with opportunities for prototyping highly dependent on personal networks in the high-technology context in the absence of flexible prototyping budgets.

A wax-based contact printing method to create microfluidic devices is demonstrated. This printing technology demonstrates a new pathway to rapid, cost-effective device prototyping, eliminating the use of expensive micromachining equipment and chemicals. Derived from the traditional Ukrainian Easter egg painting technique called “pysanky” a series of microfluidic devices were created. Pysanky is the use of a heated wax stylus, known as a “kistka”, to create micro-sized, intricate designs on the surface of an egg. The proposed technique involves the modification of an x-y-z actuation translation system with a wax extruder tip in junction with Polydimethysiloxane (PDMS) device fabrication techniques. Initial system optimization was performed considering design parameters such as extruder tip size, contact angle, write speed, substrate temperature, and wax temperature. Channels created ranged from 160 to 900 μm wide and 10 to 150 μm high based upon system operating parameters set by the user. To prove the capabilities of this technology, a series of microfluidic mixers were created via the wax technique as well as through traditional photolithography: a spiral mixer, a rainbow mixer, and a linear serial dilutor. A thermo-fluidic computational fluid dynamic (CFD) model was generated as a means of enabling rational tuning, critical to the optimization of systems in both normal and extreme conditions. A comparison between the computational and experimental models yielded a wax height of 57.98 μm and 57.30 μm, respectively, and cross-sectional areas of 11,568 μm2 and 12,951 μm2, respectively, resulting in an error of 1.18% between the heights and 10.76% between the cross-sectional areas. The device’s performance was then compared using both qualitative and quantitative measures, considering factors such as device performance, channel uniformity, repeatability, and resolution.

3D technology is considered one of the Pattern digital technologies that help this technology to increase, ease and speed of completion of industrial processes. This study deals with how to take advantage of 3D technology in developing the performance of the samples department in the technical department of ready-to-wear factories, in order to solve the problems of the samples section associated with the implementation of the 2D Pattern, as this problem was concluded through field study and practical experiences in ready-to-wear factories in Egypt.Controlling the fitting Pattern of clothes in the samples section faces many difficulties, the most important of which is the incompatibility of the industrial Pattern drawn with the human body “Pattern ". Where defects appeared in the product after conducting and implementing the first sample, which required making adjustments to the industrial Pattern and re-executing the sample a second time until it became free from defects and ready to perform the grading according to the measurements and the "order" of the operation order required to be executed to start production processes, which results in it. In the presence of lost time to implement the sample, as well as wasted effort, and wastes in the raw materials used in the implementation of the sample (fabric/ accessories / threads / and direct and indirect costs) that will be quantified after that.In order to find a solution to this problem, this research presents a case study using the "CLO5.1" program to improve the industrial Pattern in order to improve the quality of the male industrial Pattern drawing using 3D technology by making adjustments to some areas where the stress and stress ratios are high due to the lack of nan fitting of the Pattern. Industrial, which does not appear clearly even during implementation. The study concluded that the implementation of the CLO5.1 program in the sample section has succeeded in reducing the time wastage for sample production and the wastage of raw materials, thus reducing the cost of sample productionKey words :( 3Dtechnology ، pattern، Prototyping ، Garment Factories ،virtual simulation)

Prototyping is a knowledge generation activity facilitating improved understanding of problem and solution spaces. This knowledge can be generated across a range of dimensions, termed knowledge dimensions (KDs), via a range of methods and media, each with their own inherent properties. This article investigates and characterises the relationships between prototypes and knowledge generated from prototyping activities during the design process, by establishing how different methods and media contribute across KDs. In so doing, it provides insights into prototyping activity, as well as affording a means by which prototyping knowledge generation may be studied in detail. The investigation considers sets of prototypes from eight parallel 16-week design projects, with subsequent investigation of the knowledge contributions that each prototype provides and at what stage of the design process. Results showed statistical significance supporting three inferences: i) teams undertaking the same design brief create similar knowledge profiles; ii) prototyping fidelity impacts KD contribution and iii) KDs align with the different phases of the project. This article demonstrates a means to describe and potentially prescribe knowledge generation activities through prototyping. Correspondingly, the article contends that consideration of KDs offers potential to improve aspects of the design process through better prototyping method selection and sequencing.

- Abstract
-
Published in two parts, this article presents an evidence-based research and prototyping method for strategic design. In Part 1, we introduce the concept of DARN as an updated version of Actor-Network Theory (ANT). DARN is a theoretical framework used to study, rearrange, or remake the constituents of an organization or problem universe. In Part 2, we propose that DARN can be used to for several purposes. (1) It can help organizations reach their stated objectives. (2) It can define, darn, or solve organizational problems with evidence-based and collaborative design interventions. (3) It allows us to imagine new organizational models with complex and distributed agency considerations. (4) It can improve and measure the impact of design interventions within organizational strategy. The DARN approach is critical of social engineering and design solutionism. This approach proposes using collaborative strategic design in sector-agnostic organizational contexts to support designers in problematization, research, conceptualization, prototyping, testing, and impact measurement. Further, DARN presents a single frame that designers and scientists can use simultaneously without imposing an a priori language on each other. It can also serve other actors with whom they work and study. The article concludes with a practical discussion of how to apply DARN on the ground while considering its limits.

- Abstract

This article presents the first part of a study that aims at proposing an evidence-based research and prototyping methodology for strategic design. Analyzing the emergence of Strategic Design, we argue that a historically unprecedented rapprochement between intangible design and social research opens a spectrum of possibility for conducting design and science in a new way. First, we examine the emergence of strategic design and discuss its institutionalization in academic and professional contexts. Second, we summarize the three ways of approaching Strategic Design as (1) Discipline, (2) Practice and (3) Attitude. Third, drawing on the social sciences as inspired by Actor-Network Theory (ANT), we define Strategic Design as an evidence-based and social scientifically informed creative practice that aims at proposing a new way to arrange or remake the interaction between devices (D), actors (A), representations (R), and networks (N) in any given organization or problem universe. Preparing a groundwork to develop a research and prototyping methodology for strategic design, the paper ends with a methodological discussion as a segue to Part 2 (available in this issue of She-Ji) that presents DARN as a theoretical toolkit for strategic designers.

National Land Agency received requests for land rights every day. The letters can be submitted through two stages of acceptance and archiving. Still using conventional systems makes data retrieval requires relatively more time. This research aims to design and build an information system data archiving for incoming request at the National Land Agency. The software has been designed with login feature, data management land owners and land owner data search and print feature data. Analysis of system requirements using object-oriented method which uses the use-case diagram in order to illustrate the functionality of the system and some of the criteria of non-functional requirements are also outlined. The next step was the coding implementation and evaluation of the system built. The system development method used was the prototyping method. The selection of this method was intended, therefore the client can get a clear picture of the system being built. Evaluation was conducted in the developer and the user environment. The evaluation in the user environment was done by distributing questionnaires covering three parameters namely the usefulness of the application, ease of use and user satisfaction. The results showed that the information systems built have a useful value (85.7%) and are easy to use (100%), therefore it satisfied the users.
