A Reusability Assessment of UCP-Based Effort Estimation Framework using Object-Oriented Approach

Software effort estimation has become one of the most important concerns of software industries and Use Case Points (UCP) is seen as one of the most popular estimation models for object-oriented software development. Since year 2005, more than 10 UCP-based effort estimation techniques have been proposed either to give more options or to enhance the capability of UCP. However, there is no guidance for software practitioners to develop a quality UCP-based effort estimation applications. Therefore, we have proposed a new design framework for UCP-based technique to promote reusability in developing software applications. This paper will experiment and provide evidence showing that the framework achieved a good quality design using Quality Model for Objectoriented Design (QMOOD). The results showed that the framework has met five quality attributes and good to be reused as a guideline at the early stages of software development

CONCEPTUAL FRAMEWORK OF SME PRIVATE HEAL THCARE INFORMATION TECHNOLOGY ACCEPTANCE IN MALAYSIA

The advantages of healthcare information technology (HIT) usage are well documented; even then, the adoption rate of HIT by Malaysian's small and medium enterprise (SME) private healthcare are quite low compared with other SMEs type of industry. Evidence exists that user acceptance is very important for successful technology adoption and implementation. However, very limited study exists which investigate Health Information Technology (HIT) adoption, particularly for SME private healthcare or clinics in Malaysia

SCIPOG: Seeding and constraint support in IPOG strategy for combinatorial t-way testing to generate optimum test cases

Combinatorial t-way technique is efficient in generating test data and addressing the problem of combinatorial explosion. When constructing a test case, numerous literatures classified t-way strategies into two basic approaches as either One-test-at-a-time approach (OTAT) and One-parameter-at-a-time approach (OPAT). At least three major challenge groups can be encountered when creating test cases. The first one is provision of parameters seeding support that will improve the software quality. The second involves automatically obtaining data regarding parameter constraints and identifying interactions between system components. The last one is the execution speed and the test suite size. However, in all the existing OPAT t-way strategies, given that the system is loaded with this information, testing present-day software systems is made difficult or impossible. This study presents an effective combinatorial t-way test case generation strategy named Seeding and Constraint support in In-Parameter-Order Generalized (SCIPOG), to develop an improved paired testing approach. However, the study examines the present state-of-the-art and compares several OPAT strategies found in the literature. Moreover, experiments are discussed as part of this process to demonstrate the correctness of the implementation. When statistically analyzing the findings, two non-parametric tests—the Wilcoxon Rank and Friedman tests–were run. SCIPOG, however, produced competitive results. Finally, SCIPOG showed the efficiency of the two proposed methods, which are seeding and constraint support in IPOG strategy

Evaluating the quality of UCP-based framework using CK metrics

Software effort estimation is one of the most important concerns in the software industry. It has received much attention since the last 40 years to improve the accuracy of effort estimate at early stages of software development. Due to this reason, many software estimation models have been proposed such as COCOMO, ObjectMetrix, Use Case Points (UCP) and many more. However, some of the estimation methods were not designed for object-oriented technology that actively encourages reuse strategies. Therefore, due to the popularity of UCP model and the evolution of the object-oriented paradigm, a UCP-based framework and supporting program were developed to assist software developers in building good qualities of software effort estimation programs. This paper evaluates the quality of the UCP-based framework using CK Metrics. The results showed that by implementing the UCP-based framework, the quality of the UCP-based program has improved regarding the understandability, testability, maintainability, and reusability

Digital Technology Innovations and Information Security Policy Impact on Healthcare Transformation In Developing Countries

Digital healthcare technologies in developing countries face the challenges of information security (technical and behavioral). Healthcare digital transformation plays a pivotal role in the improvement of the healthcare Performance system. New impacts of emerging technology patients in the electronic health record, risk management, security tools, big data, cloud computing, and all elements needed for better information security. This paper is a simple literature review of information security impacts and involvements in digital healthcare transformation.  The literature review revealed that healthcare information security factors have a positive effect on digital healthcare transformation

Sensitivity Comparison of Refractive Index Transducer Optical Fiber Based on Surface Plasmon Resonance Using Ag, Cu, and Bimetallic Ag–Cu Layer

A single-mode optical fiber sensor uses surface plasmon resonance (SPR) with a bimetallic silver-copper (Ag-Cu) coating compared to a single layer of Ag and Cu itself. Bimetallic Ag-Cu sensors are constructed by simple fabrication on a side-polished optical fiber, followed by an electron beam evaporation of Ag and Cu films. For this investigation, the thickness of the single Ag layer was set to 30 nm and the single Cu layer was set to 30 nm; whereas for the bimetallic combined Ag-Cu layer the thickness of Ag was 7 nm and Cu 23 nm. The sensor performance was analyzed and compared experimentally and numerically using the COMSOL Multiphysics. A white light source was used with a broad optical bandwidth to provide a range of wavelengths to the optical fiber. The characteristics of the thin layers of Ag, Cu, and Ag-Cu as alcohol sensors were evaluated. We found that Cu was the most sensitive metallic layer compared to the Ag and the bimetallic Ag-Cu layers. For a 100% alcohol concentration, Cu showed a sensitivity of 425 nm/RIU followed by the bimetallic Ag-Cu layer with 108.33 nm/RIU, whereas the Ag layer was not detected. Interestingly, sensitivity reached saturation beyond the 20 nm thick layer of Ag. This shows that the Cu and the bimetallic Ag-Cu layers are suitable for an alcohol-based optical sensor. © 2020 by the authors
