The family of ISO/IEEE11073 standards is the basis of the e-health system and provides interoperability for personal health devices. In the early stage of e-health business, it was expected that people would use a health device individually. In this case, a measurement datum was episodically acquired and generally transmitted for one person at a time. Recently, a health device is expected to be used by multiple people, and large amounts of measurement data are gathered in a short time interval. In addition, mobile health devices have become more popular, so that energy efficient measurement data transmission is required, to prolong the use of a device. In IEEE11073 PHD standards, data transmission is classified into three different types: immediate individual transfer, small block transfer, and large block transfer. The large block transfer using PM-store concept provides efficient transmission. However, an existing PM-store has problem when a device is used by multiple people. To address the defined problem, a modified PM-segment that is in compliance with 11073 standards is proposed in this paper. In particular, the proposed PM-segment is designed to minimize the additional complexity of an agent instead of a manager and it is interoperable with the existing manager. The proposed PM-segment shows better performance than the existing PM-segment, in terms of memory requirements and expected queue time. Also, performance comparison among the three transfers is performed in regard to the delay time and communication power consumption points of view.

Introduction: Preplacement health examination (PHE) is performed when a worker starts a certain work task which is designated as having occupational risks by the Ministry of Employment and Labor (MOEL). All data related to health examination except PHE are reported to the MOEL by the law. This study has been performed to understand the status of PHE at certain workplaces. Methods: PHE data gathered in a university hospital were analyzed and they were followed with results of the special health examination (SHE) in 2019 and 2020. Those who were evaluated as unfit to work as it was, were interviewed directly or indirectly through an occupational health manager to follow up the management status of their recognized health problems. Results: The unfit to work (unFTW) rate of PHE was 2.8%, and was not different according to the size of workplace or having occupational health service. The major cause of unfit to work was the uncontrolled life-style diseases such as hypertension and diabetes. The rate of SHE followed by PHE was 31.1%. It was not different by the unFTW rates, however, they were different according to having a full time in-house occupational health manager. Thirty-one among 71 examinees who were evaluated as unFTW underwent SHE after controlling their health condition and were finally evaluated as fit to work. Nineteen among 31 started to take medicine and eight have been placed in the work without designated risks. Conclusion: PHE can be used for new workers, who may have unknown or uncontrolled life-style diseases, to be asked to manage life-style diseases as well as work-related risks such as shift work. In order to have a better tracking system for work-related risks, the information of PHE should be analyzed together with other data from health examination.

Medical information is one of significant private information that includes in-dividual's own diverse information. Once opened, it exposes one's health condition and medical history to a third party, which could bring about serious troubles. On this account, the third parties are of much concerns about the information. If medical information collected through various routes is used with another purpose, oilier than the initial intention, it might cause serious results beyond one's control. Thus, it is essential to keep the information confidential. Also, the discrimination based on the medical information ought to be banned because it is likely to happen that exposed information socially stigmatizes a person, being discriminated in a work place or a school when he/she is employed or gets an insurance. In the current system, only medical institutions are responsible for protecting or securing medical records. Despite the information technology development and the increased interests in medical information, there are quite a few limitations in legal, technical, and administrative aspects. All kinds of organizations, involved in collecting and using the information, as well as medical institutions primarily producing and managing it should share the responsibilities.

In view of personal health and disease management based on cost effective healthcare services, there is a growing need for real-time monitoring services. The electrocardiogram (ECG) signal is one of the most important of health information and real-time monitoring of the ECG can provide an efficient way to cope with emergency situations, as well as assist in everyday health care. In this system, it is essential to continuously collect and transmit large amount of ECG data within a given time and provide maximum user convenience at the same time. When considering limited wireless capacity and unstable channel conditions, appropriate signal processing and transmission techniques such as compression are required. However, ISO/IEEE 11073 standards for interoperability between personal health devices cannot properly support compressed data transmission. Therefore, in the present study, the problems for handling compressed data are specified and new extended agent and manager are proposed to address the problems while maintaining compatibility with existing devices. Extended devices have two PM-stores enabling compression and a novel transmission scheme. A variety of compression techniques can be applied; in this paper, discrete cosine transformation (DCT) is used. And the priority of information after DCT compression enables new transmission techniques for performance improvement. The performance of the compressed signal and the original uncompressed signal transmitted over the noisy channel are compared in terms of percent root mean square difference (PRD) using our simulation results. Our transmission scheme shows a better performance and complies with 11073 standards.

The purpose of this study was to propose how to improve and develop the college curriculum of medical record administration, satisfying requirements from hospitals having medical record administrators. For the purpose, this researcher surveyed medical record administrators serving at hospitals located in Busan, Changwon, Masan and Jinju. Finally analyzed were responses from 100 medical recorders. The frequency of searching medical records to support information use was statistically different among hospitals according to the number of sick beds(p=.041), or $3.16{\pm}1.75$ for fewer than 300 sick beds, $4.28{\pm}2.42$ for 300 to 500 and $4.86{\pm}3.18$ for more than 500. The college course that was regarded as most important by most of the surveyed medical record administrators, or 53(37.2%) was medical terminology, followed by statistics by 36 of the respondents(18.5%) and EMR, 25(12.8%) in order. To make EMR truly effective requires reforming the university curriculum of medical record administration and giving more attention and more supports to training for better computerization, realizing that medical record administrators serve as a true manager of health and medical information, not a person who just paper-based medical information. In addition to managing health and medical information, medical record administrators are expected to have more roles in the future, for example, providing high-quality clinic knowledge and medical information that are necessary for efficient hospital management and medical research to survive competition.
