IIoT stands for Industrial Internet of Things used in manufacturing, healthcare, and transportation in networked smart factories. Recently, IIoT's environment requires an automated control system through intelligent cognition to improve efficiency. In particular, IIoT can be applied to automatic calibration of production equipment for improved management in industrial environments. Such automation systems require a wireless network for transmitting industrial data. Self-calibration systems in laser transmission paths using wireless networks can save resources and improve production quality by real-time monitoring and remote control of laser transmission path. In this paper, we propose a wireless networked system for self-calibration of laser equipment that requires a laser transmission path, and we show the results of the prototype evaluation. The self-calibration system of laser equipment measures the coordinates of the laser points with sensors and sends them to the host using the proposed application protocol. We propose a wireless network service for the wired motor controller to align the laser coordinates. Using this wireless network, the host controls the motor by sending a control command of the motor controller in an HTTP message based on the received coordinate values. Finally, we build a prototype system of the proposed design to verify the detection performance and analyze the network performance.

Recently, with the advances in sensor techniques and net work computing, Ubiquitous Sensor Network (USN) has been received a lot of attentions from various communities. The sensor nodes distributed in the sensor network tend to continuously generate a large amount of data, which is called stream data. Sensor stream data arrives in an online manner so that it is characterized as high-speed, real-time and unbounded and it requires fast data processing to get the up-to-date results. The data stream has many application domains such as traffic analysis, physical distribution, U-healthcare and so on. Therefore, there is an overwhelming need of a USN middleware for processing such online stream data to provide corresponding services to diverse applications. In this paper, we propose a novel USN middleware which can provide users both context-aware service and meaningful sequential patterns. Our proposed USN middleware is mainly focused on location based applications which use stream location data. We also show the implementation of our proposed USN middleware. By using the proposed USN middleware, we can save the developing cost of providing context aware services and stream sequential patterns mainly in location based applications.

The care and quality provided to service users depend heavily on the documentation of medication administration. The results of medication management will be greatly impacted by the Medication Data Management (MDM) sheets, which will be examined during audits. Along with this impact, registered hospitals, care facilities, and residential homes will all be inspected by the healthcare industry. In order to deploy MDM sheets, it is proposed to create a blockchain prototype, or more specifically, to develop a blockchain-based Electronic Health Records (EHR) application. Confidentiality and confidence with the auditors are provided by the usage of permissioned blockchain technology (e.g., Care Quality Commission - CQC). Results from testing the prototype in two scenarios are positive. According to the findings, the use of EHR with permissioned blockchain can result in reminders being sent to medical practitioners as well as other effects.

Background: People with special needs tend to require diverse behavioral management in dentistry. They may feel anxious or uncomfortable or may not respond to any communication with the dentists. Patients with medical, physical, or psychological disorders may not cooperate and therefore require sedation (SED) or general anesthesia (GA) to receive dental treatment. Using the healthcare big data in Korea, this study aimed to analyze the trends of SED and GA in special needs patients undergoing dental treatment. It is believed that these data can be used as reference material for hospitals and for preparation of guidelines and related policy decisions of associations or governments for special needs patients in dentistry. Methods: The study used selected health information data provided by the Korean National Health Insurance Service. Patients with a record of use of one of the eight selected drugs used in dental SED between January 2007 and September 2019, those with International Classification of Diseases-10 codes for attention deficit hyperactivity disorder (ADHD), phobia, brain disease, cerebral palsy, epilepsy, genetic disease, autism, mental disorder, mental retardation, and dementia were selected. The insurance claims data were analyzed for age, sex, sedative use, GA, year, and institution. Results: The number of special needs patients who received dental treatment under SED or GA from January 2007 to September 2019 was 116,623. Number of SED cases was 136,018, performed on 69,265 patients, and the number of GA cases was 56,308, implemented on 47,257 patients. In 2007, 3100 special needs patients received dental treatment under SED while in 2018 the number of cases increased 6 times to 18,528 SED cases. In dentistry, ADHD was the most common disability for SED cases while phobia was the most common cause of disability for GA. The male-to-female ratio with respect to SED cases was higher for males (M : F = 64.36% : 35.64%). Conclusion: The application of the SED method and GA for patients with special needs in dentistry is increasing rapidly; thus, preparing guidelines and reinforcing the education and system are necessary.

CRM의 장점은 원하는 고객에 대해서 마케팅 노력을 기울일 수 있고 그 결과로 마케팅 비용을 줄이고 효율을 높일 수 있는 것이다. 그리고 마케팅 전략 수립에 대한 방법의 변화와 그 수행방법의 변화가 CRM에 있기 때문에 여기에 따른 절차와 문화, 조직구조까지 변화 시킬 수 있다. 이를 방지하기 위하여 CRM교육이 필요하며, 그 중요성을 인식하고 실행하여야 한다. 그리고 경영환경에 적합한 마케팅 전략 수립이 필수적이다. CRM의 정확한 이해와 적합한 수행이 있어야만 병원경영의 목표달성에 도움이 된다. 그러나 CRM자체의 문제가 없는 것도 아니다. 무엇보다 전문 인력이 부족하면 시스템 구축과 마케팅이나 컨설팅 인력을 확보하여 프로젝트의 부실화를 방지하여야 한다. 다음은 실업자들의 업무패턴을 파악하고 사용자의 편의를 고려한 적용이 있어야 한다. 고가의 비용을 투입하여 CRM을 실행하였다 해도 사용자 교육의 미비가 생기면 효율이 감소될 것이다. 역시 CRM의 적용에 있어서 호환이 되지 않으면 통합비용으로 별도의 비용이 지출해야 하므로 비용의 증가를 감수하여야 한다. 환자의 의료의 질에 대한 만족은 환자의 주관적 개념으로 동일한 의료서비스에 대하여 환자들은 저마다 다르게 의료의 질을 평가하게 된다. 대부분의 환자들은 자신의 욕구와 의료의 질에 대한 기대를 가지고 병원을 방문하여 의료의 질을 평가하게 된다. 대부분의 환자들은 자신의 욕구와 의료의 질에 대한 기대를 가지고 병원을 방문하여, 그것을 의료제공자가 충족시키는 정도가 환자의 만족도를 결정하게 된다. 의료의 질은 의료서비스에 대한 만족과 밀접한 관련이 있다. 의료의 질과 만족은 강하게 연관이 있으면서도 양자는 분명히 다르다. 의료의 질에 대한 평가와 만족도는 매우 일치도가 높다고 볼 수 있다. 이것은 의료의 질적 수준이 높으면 환자만족도도 높다는 것을 의미한다. 따라서 본 연구는 병원의 환자관리를 위한 CRM 마케팅의 전기를 실증적으로 역설하고 이의 도입을 통한 효과와 문제점, 이에 대한 대응방안을 제시하고, 모범적인 CRM운영 사례를 제시함과 동시에 효과적인 의료의 질 경영을 구현하고 이것이 환자의 의료서비스 만족도를 높이는 결과인 것을 모색하는 것이 본 연구의 목적이다.

The purpose of the study is to identify the barriers to using mobile health applications based on the Diffusion of Innovations Theory. The study employed a purposive sampling to recruit college students who were non-adopters or rejecters. The study participants were a total of 44 students, who consist of 32 males and 12 females, and paper-based interviews were conducted. The findings of the study indicated that attributes such as relative advantages, complexity, trialability and observability were not considerable factors of impeding the adoption or continuous use of health applications, whereas relative disadvantages and compatibility were. The study suggests that health application developers and service providers minimize relative disadvantages and enhance compatibility of the innovation with consumers' life styles, rather than try to improve relative advantages and complexity, to more effectively encourage non-adopters to try and maintain using the innovation.
