  • The stethoscope has long been used for the examination of patients, but the importance of auscultation has declined due to its several limitations and the development of other diagnostic tools. However, auscultation is still recognized as a primary diagnostic device because it is non-invasive and provides valuable information in real-time. To supplement the limitations of existing stethoscopes, digital stethoscopes with machine learning (ML) algorithms have been developed. Thus, now we can record and share respiratory sounds and artificial intelligence (AI)-assisted auscultation using ML algorithms distinguishes the type of sounds. Recently, the demands for remote care and non-face-to-face treatment diseases requiring isolation such as coronavirus disease 2019 (COVID-19) infection increased. To address these problems, wireless and wearable stethoscopes are being developed with the advances in battery technology and integrated sensors. This review provides the history of the stethoscope and classification of respiratory sounds, describes ML algorithms, and introduces new auscultation methods based on AI-assisted analysis and wireless or wearable stethoscopes.

  • Conversation modeling is an important and challenging task in the field of natural language processing because it is a key component promoting the development of automated humanmachine conversation. Most recent research concerning conversation modeling focuses only on the current utterance (considered as the current question) to generate a response, and thus fails to capture the conversation's logic from its beginning. Some studies concatenate the current question with previous conversation sentences and use it as input for response generation. Another approach is to use an encoder to store all previous utterances. Each time a new question is encountered, the encoder is updated and used to generate the response. Our approach in this paper differs from previous studies in that we explicitly separate the encoding of the question from the encoding of its context. This results in different encoding models for the question and the context, capturing the specificity of each. In this way, we have access to the entire context when generating the response. To this end, we propose a deep neural network-based model, called the Context Model, to encode previous utterances' information and combine it with the current question. This approach satisfies the need for context information while keeping the different roles of the current question and its context separate while generating a response. We investigate two approaches for representing the context: Long short-term memory and Convolutional neural network. Experiments show that our Context Model outperforms a baseline model on both ConvAI2 Dataset and a collected dataset of conversational English.

  • Recent complex visual culture is the visual world widely magnified according to the images like image, graphics, photograph, movie, and television, etc. by the development of digital technology. Because it conveys meanings and contents inserting sound and letters, it may have multimedia character conveying and communicating information beyond general language and letters. The vision for various images at that time is inseparably connected with language. And imaginative order of image and vision are composed of special way in culture and history. Language is different in society, culture, and history. Accordingly, if visual experience is communicated with language partially, it is difficult to have university. So, role of linguistic order plays an important role in forming and defining the social and cultural differences among the visual systems. Historically various visual and optical devices with this visual language have influenced a lot. These visual technologies are concrete and physical practice determining a way to get together with the subject and the visible object in the visible world. The visual language is connected with dimension like these symbols of images and the dimension like visual technologies to series of historical physical and institutional practices. It determines social visual mode toward object world in one of visual system. Accordingly, this study is to understand visual language with social and historical character according to the changed concept and characters as development of media technology. And it is to explain it in view of visual language as a dimension of symbol and visual technology of institutional and physical practice. After all, it cannot explain the effect on the function and visual mode of visual technology as its technical element only. It also cannot separate with the practice with coherent discourse and the physical and institutional practice. The possibility, technical element of technology contains, does not realize as it is but the effect is always communicated in the social veins and realized with a restriction.

  • The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS in haste. However, while many older HIS and PACS systems are not yet capable of some of the integration, several new systems are moving rapidly in that direction. Typical PACS system architecture begins with the HIS since this is where the correct patient demographic information and in many cases the orders originate. So, PACS developed convenience of users and to satisfy user's demand because of financial limitations and administrator-oriented considerations in the process of development. Therefore, we have developed a CDA (Clinical Document Architecture) based PACS with HIS, by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. Target model of this research limited to 135 of hospital have 200 beds. We'll make more effort to develop the application which insures the better quality and information of medical images. Medical Image History manages the patient's image files and various medical informations like film chart in connection with time. This trial will contribute to the reduction of the financial loss caused by unnecessary devices and improve the quality in the medical services. The demand on the development of the program which refers to the medical data quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that the program will be modified from the standpoint of the users.
