Abstract

This paper presents an implementation of Least Significant Bit (LSB) steganography to embed a hidden watermark in batik digital images. The goal of the technique is to provide a means of protecting the intellectual property of creators of batik digital arts while still allowing the images to be freely distributed and shared. The study demonstrates the effectiveness of the technique by showing that the embedded watermark is not visible to the human eye and does not significantly alter the quality of the image. The proposed technique uses the LSB method to embed a watermark in the binary data of the batik digital image. This method involves replacing the least significant bit of the image's pixel values with the bits of the watermark, thus altering the binary data of the image without causing noticeable changes in its visual appearance. The embedded watermark can only be detected by a decoding process, making it difficult to be removed or tampered with. The results of the study show that the implemented LSB steganography technique is successful in achieving its objective. The technique is able to effectively embed a hidden watermark in batik digital images without significantly altering the image quality or causing visual artifacts. This work highlights the potential of LSB steganography as a valuable tool for protecting the intellectual property of digital art creators, particularly in the field of batik images. Overall, this study contributes to the growing body of research on steganography and digital media protection. The successful implementation of the LSB steganography technique provides a promising approach for safeguarding the intellectual property of creators in the digital arts industry. Future research may explore other steganography techniques to address potential vulnerabilities and limitations of the LSB method.

Abstract

Artificial intelligence (AI) has shown promising potential to transform various fields, including medical education. Recently, the rapid advancement of AI has led to many ``new'' discoveries that caught everyone's attention. Among those discoveries are introduced by OpenAI (e.g., ChatGPT, Dall-E, and the most recent, GPT-4). The integration of AI tools, such as ChatGPT and Dall-E, can offer a new dimension to medical education by creating an interactive and engaging learning experience. In this article, we explore the potential benefits of ChatGPT and Dall-E in medical education and provide practical utilization examples of those tools. For starters, ChatGPT, or in this sense, any other similar large language models, can simulate patient interactions in a safe environment, allowing medical learners to practice their communication skills and diagnosis techniques. Furthermore, it can assist medical students and researchers in reading and writing academic articles by accurately summarizing the key points of a given topic and generating an indistinguishable abstract. In addition, ChatGPT can also create problems for medical assignments and exam practice. In this article, we also discussed ChatGPT's capability to answer standard medical assignment problems. Dall-E, on the other hand, can generate dummy copyright-free and consent-free medical images (e.g., x-ray and electrocardiogram (ECG) graphs), allowing medical learners to practice and enhance their interpretation skills. Incorporating AI-based tools into medical education can provide a new approach to teaching and learning, bridging the gap between theory and practice, and unlocking new avenues for learning and discoveries for both, the students and the instructors. It can also offer a cost-effective solution to simulate real-world scenarios that would otherwise require significant resources and time. In summary, this article concludes that AI-based tools have the potential to revolutionize medical education, empowering medical learners with the skills and knowledge necessary to excel in their field.

Abstract

Nowadays, implanted permanent pacemakers (PPM) users need to undergo periodic pacemaker replacement surgery. The surgery is needed since the pacemaker's battery is usually depleted in 5-10 years. This surgery, although poses relatively low health risks, is inconvenient for PPM users. Moreover, the surgery can still be dangerous for PPM users, especially considering that most of the users are elderly. PPM replacement surgery is also costly. In addition to the costs of the surgery itself, the PPM users need to bear the price of the new PPM every time they undergo surgery. Currently, when the PPM's battery runs out, the whole PPM needs to be replaced. This is conducted to prevent the possibility of a leak in the battery seal, which might allow the body fluids to enter the PPM. Typically, once a battery is inserted into the PPM, it will be permanently sealed along with all other electronic components, and thus, battery-only replacement is impossible. Thanks to the recent advancement of wireless power transfer (WPT) technology, a PPM replacement surgery might no longer be necessary in the near future. This article presents a brief review of the current state of coil-based WPT technology and its potential applications in pacemakers. Depending on the load and transmission distance, a recent WPT system for PPM could achieve WPT efficiency as high as 97.91% on air and 78% on pig tissue medium. In terms of output power, recent works that we have summarized showed that they are able to transmit power up to 5W on a WPT system implemented on a human phantom. We also discuss the challenges, limitations, and future prospects for WPT in the medical field, particularly for PPM applications.

Abstract

This article provides a comprehensive review of implantable antennas in the context of their application within the biomedical field. Through a systematic exploration of cutting-edge developments and associated challenges, a thorough understanding of antenna design, performance considerations, and safety implications is obtained. The investigation thoroughly examines diverse antenna types, including planar, microstrip, fractal-geometry, and others, elucidating the design considerations that govern their suitability for a wide array of implantable medical devices (IMDs). Substrate and material choices are critical factors influencing antenna efficiency and biocompatibility. The utilization of available frequency bands is evaluated, highlighting the inherent tradeoffs that dictate their applicability in biomedical applications. Additionally, the promising domain of rectenna technology is explored for its potential in sustainable energy harvesting. The discourse on miniaturization techniques underscores their pivotal role in enabling the seamless integration of antennas within intricate implant structures. Safety aspects are paramount, encompassing metrics such as specific absorption range (SAR), maximum permissible exposure (MPE) limits, and thresholds for localized temperature changes. The intricate interplay between human body effects and antenna performance is briefly elaborated. Methodologies for thorough evaluation, spanning computer simulations, as well as experiments in in vivo and in vitro scenarios, are discussed for their pivotal role in iteratively refining antenna functionality.

Abstract

This study investigated the association between job burnout and flexible working arrangement on employee wellbeing with perceived organizational support as a mediator. The study is conducted on 127 employees of an Indonesian telecommunication company. The data is obtained between November 2021 and January 2022 using an anonymous online survey. We employ the partial least squares-structural equation modeling (PLS-SEM) method to analyze the data. The result finds that the level of employees' job burnout is in a low category. In addition, the employees have a positive view of the FWA implementation. As for POS, the employees perceive adequate POS. The findings also reveal that the employees have a sufficiently good well-being level. Furthermore, the statistical analysis shows that the POS variable is influenced by JB and FWA variables; and has a positive and significant effect on the EW variable. In addition, JB and FWA variables have a positive and significant effect on EW, either directly or mediated by the POS variable. Note that this research was conducted at the branch of the telecommunication company at a province level. Hence, the result might not represent the employees throughout Indonesia. Moreover, the variables of interest were limited to job burnout, FWA, POS, and employee wellbeing, making a relatively limited number of operational variables. Finally, the research findings contribute to the HRM to improve the organization through employee wellbeing management.
