Wer sing Sie

Wer sind Sie? is a user authentication system designed for a distributed environment. The thesis is named such because user authentication deals with the question Who are you?. In Germany, who are you? is Wer sind Sie? . In a distributed system, data security is a serious concern. Unauthorized access to the system is one major factor of data loss. The system, therefore, should provide a security measure which ensures one simple condition: Every access by a user should be made by a valid user. Two main issues involved in the security of distributed systems, particularly in user\u27s access, are authentication and authorization. Authentication is the process of verifying a user\u27s identity. It answers the question Who said this? . Authorization, on the other hand, entails determining whether the user has the right to access a particular service and the access method to the resource. Authorization answers the question Who is trusted to access this? . If the user had successfully passed the authentication process, he/she will be allowed to access the services of the system, and this will be determined by the authorization process. Moreover, distributed systems run in an insecure network communications environment wherein problems, which may arise, will have to be solved. Studies have been conducted on existing user authentication algorithms. An analysis of each existing systems have given the proponents the limitations of the existing systems. With the limitations of the existing system that served as the metrics for the new algorithm, principles in making a authentication protocol and proving tools for user authentication algorithms, \u27Wer sind Sie\u27 was developed by the group

A comparative study on the effectiveness of purely online and hybrid learning modes on the academic performance and learning experience of accountancy students in taxation courses of De La Salle University – Manila: A cross-sectional study

CHED Memorandum Order No. 16-2022 gave higher education institutions the prerogative to continue delivering in hybrid learning modes while requiring specific approval for online classes, despite having limited justifications. Given that a few studies investigated the delivery of accounting education in online and hybrid learning modes gave an insight into the perceived effectiveness of students, the researchers sought to contribute to filling the research gap. Thus, this study compared the academic performance and learning experience of purely online and hybrid learners in terms of content absorption, skills development, and interaction in Taxation 1, Taxation 2, and Taxation 3 courses offered by De La Salle University - Manila during the first term of the Academic Year 2022 to 2023. Convenience sampling was used to select respondents who answered validated online questionnaires with a 0.875 Cronbach\u27s alpha reliability rating. These questionnaires contained items adapted and revised from related literature. Moreover, due to the asymmetrical data distribution and sample size imbalances, the Mann-Whitney U test was used to address the research objectives. The findings indicate that purely online learning is comparable to hybrid learning in academic performance and learning experience in ACTTAX1 and ACTTAX3, and it outperforms hybrid learning in ACTTAX2. The study credits this to reduced transactional distance and significant presence based on the Theory of Transactional Distance and Community of Inquiry Framework. Moreover, perceived effectiveness improved progressively from ACTTAX1 to ACTTAX3, suggesting that increased exposure and familiarity with Taxation topics contributed to this progression. Key Words: purely online learning; hybrid learning; perceived effectiveness; academic performance; learning experienc

A systems study on the production of Sony television cabinets of Solid City Industrial and Commercial Corporation

Solid City Industrial and Commercial Corporation (SCICC) traces its roots from its mother company, Solid Corporation (SC). It started as a plastics division of SC but decided to span off in 1988 to increase their market. SCICC is engaged in manufacturing industrial products (T.V. and radio cabinets, refrigerator and automotive parts) and commercial products (ballpen caps, tupperware. beercrates). It ventures into the manufacture of export quality plastic casings and components establishing a sterling record of performance and capability in all aspects of plastic molding.SCICC competes in the plastic processing industry. In 1993, SCICC gathered the largest market share, ranking number one in the plastics processing industry, specifically in the production of plastic casings of television cabinets.The study focuses on the production of Sony T.V. cabinets as it constitutes an 80 share of the total T.V. cabinets produced. The study shall concern itself with the Operations Department, as well as its support function groups, namely, the Manufacturing Resource Planning Department (MRPD), the Quality Assurance Department (QAD), and the Engineering and Maintenance Department (EMD). These will be studied in detail in terms of man, machine, materials and methods. After a careful analysis of the weaknesses regarding their respective seriousness, urgency, resources and growth, the problem identified is: SCICC is experiencing an average rework and reject of 1050 unts/mo. and 21 units/mo. respectively for the 14BMX1 and 1184 units/mo. and 32 units/mo. respectively for the 21BMR1 front T.V. cabinets.The problem is caused by the following: poor layout of the Painting Department, poor design of the present jig, lack of training and quality awareness among workers, poor monitoring and controlling procedure, worn-out silk-screen and clogged nozzle of spray gun. The effects of the problem, on the other hand are overtime cost amounting to P 1,358,703.92 per year, opportunity loss of P 856,052.60 per year due to penalty, delivery cost of P 141,000 per year and loss of customer goodwill.To solve the problem of production delay of front T.V. cabinets, the group proposes the following: (1) modification of the present layout of the Painting Department (2) re-designing the present jig used in the painting booth (3) conduct a TQM seminar for top management and workers (4) implement autonomous inspection and post reminders (5) purchase new sil-screens and (6) purchase new spray guns.With the proposed system, a total initial cost of P40,200.00 and a total yearly cost of P294,060.00 will be incurred. Based from the proposed system, however, the company will be able to generate a yearly benefit amounting to P2,252,142.82. With this, the proponents affirm the feasibility and acceptability of the proposed system.In terms of implementation, the run of the proposed solutions will be executed for a period of 9 weeks. Finally, for further studies, it is recommended that future studies be focused on the recalibration of machines and upgrading of molds to minimize, if not to eliminate, the product weight deviation currently experienced by SCICC
