Cashier App Revolutionizes Internal Controls in Global Enterprises

This study evaluates the effectiveness of cashier application-based cash receipt systems as internal controls in small-scale enterprises, focusing on Lugo Coffee House in Tulungagung, Indonesia. Through qualitative analysis of interviews, observations, and document reviews, the study examines the functionality and integration of internal controls within these systems. Findings indicate that while the systems demonstrate efficiency in transaction processing and record-keeping, deficiencies such as the absence of task segregation pose potential risks. Nonetheless, the overall sufficiency of these systems in mitigating financial risks is affirmed. The study highlights the importance of optimizing cashier application-based systems to enhance financial management practices and minimize risks associated with cash transactions in similar organizational contexts. Highlights: 1. Assessing cashier app systems in small enterprises.2. Identifying internal control strengths and weaknesses.3. Optimizing financial management to minimize risks. Keywords: Cashier application, Internal controls, Small-scale enterprises, Financial management, Risk mitigation.

Feasibility and Utility of Mobile Applications for the Evaluation of Urology Residents’ Surgical Competence

To provide real-time assessment and feedback on the competency of urology residents' surgical skill via mobile applications and examine their feasibility and utility. Two mobile application-based systems (SIMPL and myTIPreport) were sequentially implemented for the case-by-case assessment of residents' performance of surgical skills at a single institution. Data was collected regarding residents' perception of their feedback pre- and post-implementation of the applications. Faculty were surveyed after their implementation to determine their feasibility and utility. 297 individual evaluations were completed with SIMPL and 822 with myTIPreport over four and eleven months respectively. Post-implementation, residents showed significantly improved perceptions regarding the quantity and personalization of surgical skill feedback (P = .043 and .005 respectively). A majority (75%) of the faculty found the mobile applications feasible to use, an improvement compared to prior methods of resident evaluation, and would recommend continued use. This study represents the first documented use of real-time surgical competency assessment in urology. The use of mobile applications to evaluate urology residents' surgical competency in clinical practice is both feasible and useful. Their use may allow for more individualized surgical skill teaching during training and for the verification of the surgical skills necessary to practice autonomously.

Mobile application security system (MASS)

Security is an important factor in any network, but particularly in a wireless ad-hoc network in which mobile applications are employed to perform various tasks. By mobile applications, we mean applications that can support both moving nodes (e.g., transmitter/receiver mounted on a moving vehicle) and migrating code (i.e., code that can transport itself via wireless link from one execution node to another). These networks remain more vulnerable to compromise by malicious applications and hosts due to their innate characteristic of no clear line of defense. We devised a potential solution to this problem that addresses critical aspects of security in ad-hoc mobile application networks. This approach involves preventing unauthorized modification of a mobile application, both by other applications and by hosts, and ensuring that mobile code is authentic and authorized. These capabilities constitute the Mobile Application security system (mass). The MASS applies effective, robust security to mobile application-based systems, wireless, and wired networks while minimizing overhead requirements. The MASS consists of innovative security techniques that provide distributed security solutions for mobile application networks.

DESIGN LEVEL HYPOTHESIS TESTING THROUGH REVERSE ENGINEERING OF OBJECT-ORIENTED SOFTWARE

Comprehension of an object-oriented (OO) system, its design and use of OO features such as aggregation, generalisation and other forms of association is a difficult task to undertake without the original design documentation for reference. In this paper, we describe the collection of high-level class metrics from the UML design documentation of five industrial-sized C++ systems. Two of the systems studied were libraries of reusable classes. Three hypotheses were tested between these high-level features and the low-level class features of a number of class methods and attributes in each of the five systems. A further two conjectures were then investigated to determine features of key classes in a system and to investigate any differences between library-based systems and the other systems studied in terms of coupling. Results indicated that, for the three application-based systems, no clear patterns emerged for hypotheses relating to generalisation. There was, however, a clear (positive) statistical significance for all three systems studied between aggregation, other types of association and the number of methods and attributes in a class. Key classes in the three application-based systems tended to contain large numbers of methods, attributes, and associations, significant amounts of aggregation but little inheritance. No consistent, identifiable key features could be found in the two library-based systems; both showed a distinct lack of any form of coupling (including inheritance) other than through the C++ friend facility.
