A multi-purpose image-based QR code is designed in this paper. There are four purposes for the generated image-based QR code. In the first purpose, the basic image-based QR code with the look of a host image is with an ingenious layout to be identified easier. In the second one, a saliency region detection method is adopted for enhancing the quality of the image-based QR code. In the third one, the host image is embedded into the image-based QR code for further access to the host image; Finally, the visual cryptography-based watermarking method is applied to the host image embedded image-based QR code. In the case that the specific users need verification from the image-based QR code, the binary verified image can be retrieved when the public share is available. The experimental results demonstrate that the generated image-based QR code not only looked better than some previous works but also had high quality host image embedded and identification ability.

Quality Of Products

AbstrakMakanan adalah salah satu hal penting dalam kehidupan masyarakat. Semakin berkualitas suatu makanan maka dapat menghasilkan sumber daya manusia yang berkualitas juga. Akan tetapi maraknya pemalsuan salah satunya pemalsuan tanggal kadaluarsa mengakibatkan masyarakat harus jeli dan teliti dalam memilih produk. Salah satu makanan yang digemari masyarakat adalah jenis kue dan bolu. Toko Kemuning salah satu toko yang banyak memproduksi jenis-jenis kue tersebut untuk didistribusikan dan dijual sendiri di tokonya. Oleh karena itu, untuk meningkatkan kepercayaan masyakarat terhadap kualitas produk yang dihasilkan oleh Toko Kemuning maka pada penelitian ini dibuat sebuah aplikasi untuk mengelola data produk, dimana konsumen dapat mengecek tanggal kadaluarsa melalui anroid dengan cara scan qr code yang terdapat dalam kemasan kue. Adapun yang digenerate ke dalam bentuk qr code adalah id produk,id tersebut berisi string unik yang dienkripsi menggunakan algoritma vigenere chipper sehingga tidak mudah dideteksi oleh orang lain. Admin dapat melakukan pengelolaan data produk sehingga ketika toko memproduksi kue, data dapat tersimpan di database dan qr code dapat dicetak. Dengan penelitian ini diharapkan dapat meningkatkan kepercayaan konsumen derta menjaga kualitas produk dari toko kemuning.Kata Kunci��Kue, Enkripsi, Algoritma Vigenere Chiper�AbstractFood is one of the important things in people's lives. The more quality a food can produce quality human resources as well. However, the rise of counterfeiting, one of which is falsification of expiration date, causes the public to be observant and careful in choosing products. One of the foods that are favored by the public is a type of cake and sponge cake. Kemuning Shop is one shop that produces many types of cakes to be distributed and sold alone in the store. Therefore, to increase public trust in the quality of products produced by the Kemuning Shop, an application is made to manage product data, where consumers can check the expiration date via anroid by scanning the qr code contained in the cake packaging. As for what is generated in the form of qr code is a product id, the id contains a unique string that is encrypted using the vigenere chipper algorithm so that it is not easily detected by others. Admins can manage product data so that when a shop produces cookies, data can be stored in a database and the QR code can be printed. With this research it is expected to increase consumer confidence and maintain product quality from kemuning shops.�Keywords��Cake, Encription, Vigenere Chiper Algorithm

<p align="justify">As the main executor of accounting information disclosure, listed companies are more likely to be favored by investors, suppliers, management departments, the public and other stakeholders. They will also be better than non listed companies in the performance of corporate social responsibility, and will disclose more information in the disclosure of environmental accounting information. The information of listed companies is relatively open and transparent. The annual major events public, annual report, interim report, interim report and environmental report are published on the corresponding websites for the convenience of information collection and collation. The quality requirement of accounting information is to meet the needs of stakeholders, so that they can make correct decisions with the useful information. However, there are some problems in the disclosure of accounting information due to the imperfection of the relevant system and the inadequate supervision.</p>

There has been an increasing drive to improve total quality management of manufactured products internationally in recent years. This has resulted in many improvements in the quality and management of quality in New Zealand firms. Research was carried out in New Zealand to compare the opinions of manufacturing company managers about product quality with general public opinions. Probes perceptions of recent changes in product quality and compares the quality of New Zealand made goods with the quality of those made overseas. Most managers and consumers agreed that the quality of New Zealand made goods is now better than most overseas made goods. Shows a great improvement in the public perception of New Zealand made goods in recent years. Managers are still much stronger than consumers in their belief in local made high quality, which may have resulted in some complacency regarding management of product quality.

Radon exposure to the public contributes more than half of all the radiation doses caused by natural radiation; accurate measurement of radon progeny is quite essential for the dose evaluation of radon exposure in environment. For the purpose of establishing a radon progeny standard and controlling measurement quality of commercial devices, it is quite important to analyze the efficiency of different measurement methods and determine which would be the most appropriate for radon progeny measurements. Through theoretical analysis and experimental measurement, some commonly used measurement methods were compared in this study and the development trends of those methods were reviewed. Results show that for radon progeny measurement, the spectroscopic analysis method is better than the gross count method, while least-square calculation methods is better than traditional three-count or five-count method. Multiperiod counting ofαplusβspectrum as well as using weighted least-square calculation method might be the best choice for accurate measurement on radon progeny in standard radon chamber when calibrating commercial radon progeny monitors.

This descriptive study explored the quality of teachers’ performanceevaluation process used in schools of Karachi city. The sample of thisstudy included 50 principals and 250 teachers from public and privateschools. Using structured, closed-ended questionnaire, data wereanalyzed by descriptive statistics and Independent t test. The results ofthe study indicate that both private and public secondary schools inKarachi have a proper system of teachers’ performance evaluation but asignificant difference exists in terms of quality. Unlike private schools,the performance of teachers in public schools is not monitored regularly,the results of performance evaluation do not accurately reflect a teacher’sability, and the rating system used to evaluate teachers is not useful forthe growth of teachers and principals. The results concluded that bothpublic and private secondary schools in Karachi have a trustworthysystem of teachers’ performance evaluation. The study also revealed thatthe quality of teachers’ performance evaluation in private secondaryschools is better than public secondary schools in Karachi. The privateschools have a formative system of teachers’ performance evaluation thatis reflected through regular informal visits by their principal to check theperformance of teachers. In contrast the public schools have a summativeevaluation system to check the performance of teachers which wasreflected through lack of regular visits by principal to check theperformance of teachers.

Heuristic Information Processing

Abstract. Comments sections under news articles have become popular spaces for audience members to oppose the mainstream media’s perspective on political issues by expressing alternative views. This kind of challenge to mainstream discourses is a necessary element of proper deliberation. However, due to heuristic information processing and the public concern about disinformation online, readers of comments sections may be inherently skeptical about user comments that counter the views of mainstream media. Consequently, commenters with alternative views may participate in discussions from a position of disadvantage because their contributions are scrutinized particularly critically. Nevertheless, this effect has hitherto not been empirically established. To address this gap, a multifactorial, between-subjects experimental study ( N = 166) was conducted that investigated how participants assess the credibility and argument quality of media-dissonant user comments relative to media-congruent user comments. The findings revealed that media-dissonant user comments are, indeed, disadvantaged in online discussions, as they are assessed as less credible and more poorly argued than media-congruent user comments. Moreover, the findings showed that the higher the participants’ level of media trust, the worse the assessment of media-dissonant user comments relative to media-congruent user comments. Normative implications and avenues for future research are discussed.
