Dengan berkembangnya teknologi informasi, sering sekali terjadi penyelewengan dokumen terutama pada dokumen-dokumen cetak. Dokumen merupakan salah satu data yang sangat penting, karena dokumen merupakan sumber informasi yang diperlukan oleh suatu instansi, organisasi, negara, maupun individu. Tanpa dokumen, maka seseorang akan kehilangan data-data yang diperlukan untuk kegiatan di masa yang akan datang. Pemalsuan dokumen sangat mudah dilakukan dengan cara meniru bentuk serta isi dari suatu dokumen. Penelitian sebelumnya pernah dilakukan, namun dalam objek yang berbeda. Pemalsuan dokumen dapat diatasi dengan menggunakan Quick Response (QR) Code. QR Code mampu menyimpan semua jenis data, seperti data angka/numerik, alphanumeric, biner, kanji/kana. Selain itu QR Code memiliki tampilan yang lebih kecil daripada barcode. Untuk dapat membuat QR Code suatu dokumen maka dibuatlah sebuah aplikasi yaitu aplikasi Validasi Dokumen. Aplikasi Validasi Dokumen dirancang dengan menggunakan metode waterfall serta menggunakan perancangan Unified Modelling Language (UML). Bahasa pemrograman yang digunakan yaitu bahasa pemrograman PHP: Hypertext Preprocessor (PHP) dengan database MySQL. Sebelum QR Code dibuat, terlebih dahulu data dokumen dienkripsi dan kemudian dijadikan QR Code. Hasil pemindaian QR Code berupa Uniform Resource Locator (URL) yang mengarah pada data dokumen. Ketika URL dijalankan pada web browser, sistem melakukan deskripsi pada URL, kemudian dicocokkan dengan database, dan selanjutnya ditampilkan ke web browser. Hasil akhir aplikasi Validasi Dokumen berupa QR Code yang digunakan untuk menyimpan URL yang  menunjukkan bahwa dokumen memang benar-banar dokumen yang resmi (bukan ilegal) dari suatu instansi. Pada uji coba penelitian ini juga dilakukan perbandingan kinerja dengan 3 aplikasi yang sejenis, 3 aplikasi pembanding tersebut dipilih karena memiliki hasil visual QR Code yang hampir mirip, namun jika dilakukan scanning memiliki hasil yang berbeda, karena fiturnya juga berbeda. Berdasarkan hasil pengujian dengan 3 pembanding aplikasi yang sejenis, dengan menggunakan aplikasi yang diusulkan dalam penelitian ini, pemalsuan dokumen dapat dihindari dengan menggunakan aplikasi Validasi Dokumen selama tidak ada ikut campur orang dalam (superadmin/admin) dalam melakukan praktik pemalsuan dokumen. Pada penelitian selanjutnya dapat dilakukan perbaikan kelemahan aplikasi ini, yaitu agar tidak menampilkan URL, namun hasil pemindai QR Code, langsung dapat menampilkan detail isi dokumen.

Aim and Objective: Ultrafine Ag/ZnO nanotetrapods (AZNTP) have been prepared successfully using silver (I)–bis (oxalato) zinc complex and 1, 3-diaminopropane (DAP) with a phase separation system, and have been injected into a diethyl/water solution. Materials and Methods: This crystal structure and lattice constant of the AZNTP obtained were investigated by means of a SEM, XRD, TEM and UV-vis spectrum. Results: The results of the present study demonstrated the growth and characterization AZNTP for humidity sensing and DAP plays a key role in the determination of particle morphology. AZNTP films with 23 nm in arm diameter have shown highly sensitive, quick response sensor material that works at room temperature.

Traceability is considered a promising solution for product safety. However, the data in the traceability system is only a claim rather than a fact. Therefore, the quality and safety of the product cannot be guaranteed since we cannot ensure the authenticity of products (aka counterfeit detection) in the real world. In this paper, we focus on counterfeit detection for the traceability system. The risk of counterfeiting throughout a typical product life cycle in the supply chain is analyzed, and the corresponding requirements for the tags, packages, and traceability system are given to eliminate these risks. Based on the analysis, an anti-counterfeiting architecture for traceability system based on two-level quick response codes (2LQR codes) is proposed, where the problem of counterfeit detection for a product is transformed into the problem of copy detection for the 2LQR code tag. According to the characteristics of the traceability system, the generation progress of the 2LQR code is modified, and there is a corresponding improved algorithm to estimate the actual location of patterns in the scanned image of the modified 2LQR code tag to improve the performance of copy detection. A prototype system based on the proposed architecture is implemented, where the consumers can perform traceability information queries by scanning the 2LQR code on the product package with any QR code reader. They can also scan the 2LQR code with a home-scanner or office-scanner, and send the scanned image to the system to perform counterfeit detection. Compared with other anti-counterfeiting solutions, the proposed architecture has advantages of low cost, generality, and good performance. Therefore, it is a promising solution to replace the existing anti-counterfeiting system.

The Impact

Background:Responsive behaviours in dementia are associated with poor outcomes for the person with dementia (PWD) and caregiver burnout. Family caregivers need a variety of tools to manage responsive behaviours. The Baycrest Quick-Response Caregiver Tool was developed to provide caregivers with a tool that can be used in real time. In this study, the feasibility, impact, and effectiveness of this new tool were studied in family caregivers and health care providers (HCP) using quantitative and qualitative measures.Methods:Family caregivers were recruited and were asked to complete a pre-survey before being sent the link to the educational tool. One month after the telephone survey, caregivers were sent an online post-survey to gather their feedback on the tool and the impact of the tool on caregiver well -being. Healthcare providers were also recruited and reviewed the tool through an online feedback survey. The feasibility, impact, and effectiveness of the tool were assessed using quantitative and qualitative measures.Results:Caregivers had a moderate degree of and reported a high level of competence - these scores were maintained throughout the study. Caregivers reported that tool positively impacted their compassion towards the person with dementia (PWD), and that their interactions with improved. 100% of HCP who completed the feedback survey would recommend the tool to other HCP and to caregivers of PWD. The caregivers and HCP provided specific suggestions for improvement.Conclusions:The Baycrest Quick-Response Caregiver Tool was found to be feasible and helpful. It provides caregivers and HCP with an additional approach for responsive behaviours.
