With the development of medical technology, interest in rehabilitation devices is increasing and various devices are being studied. In particular, devices for speech disorders such as hearing impairment and cleft palate are attracting attention. In general, the nasometer is used for patients with flaccid dysarthria and velopharyngeal incompetence(VPI). However, in the case of the conventional separator type nasometer, that has an acoustic feedback problem between the oral and nasal sounds. In recent, the mask type nasometer has been developed which is insensitive to acoustic feedback. But, still not popularized. In this paper, the nasometer characteristics of the conventional separation type and mask type are analyzed. Also, We were obtained clinical acoustic data from the 6 subjects and examined the significant differences in the structure of the separation type and mask type nasometer. Through experiments, it was confirmed that the measurement was about 3~15% higher in the mask type nasometer than the conventional nasometer having a separator type. Also, We was considered the necessity of nasometer signal processing for acoustic feedback reduction and nasalance calculation optimization.

U-healthcare, which grafted advanced IT technology onto medical technology, is in the limelight because it can provide medical services at anytime and anywhere. U-healthcare system applied RFID technology for Implantable Medical Device (IMD), but patient's biometric information can be easily exposed to third parties. In this article, RFID-based U-healthcare authentication protocol is proposed to prevent illegal usage for personal biometric information exposed to the third patty. The proposed protocol guarantees patients' biometric information integrity as compounding random numbers between administrators and hospital/clinic managers, and uses continuous number SEQ and time stamp T to synchronize IMD/administrators and administrators/hospital managers. Also, to protect user's privacy from the third party, patients' biometric information can be safely guarded by managing patients' security identifiers by administrators.

Advancements in remote medical technologies and smart devices have led to expectations of contactless rehabilitation. Conventionally, rehabilitation requires clinicians to perform routine muscle function assessments with patients. However, assessment results are difficult to cross-reference owing to the lack of a gold standard. Thus, the application of remote smart rehabilitation systems is significantly hindered. This study analyzes the factors affecting the real-time evaluation of muscle function based on biometric sensor data so that we can provide a basis for a remote system. We acquired real clinical stroke patient data to identify the meaningful features associated with normal and abnormal musculature. We provide a system based on these emerging features that assesses muscle functionality in real time via streamed biometric signal data. A system view based on the amount of data, data processing speed, and feature proportions is provided to support the production of a rudimentary remote smart rehabilitation system.

The purpose of this study was to investigate the home care needs in a rural county as a basic study to develop a Korean home care model. A stratified cluster sampling method was used to select 1, 352 household which accounted for 8.8% of Youn Cheon County population. A Standard criterias for home care subject were delineated by five nursing professors representing five different areas of nursing specialty. The developed criteria for home care subjects were as below, 1) Patients who had been discharged from hospital during the previous week. 2) Patients with special medical devices 3) Newborns and the mothers. 4) The chronically ill with poor recovery or control of disease. 5) Subjects with poor health care behavior or ability 6) Subjects with poor social support and / or family resources. 7) Subjects with health related educational needs. Three types of questionnaires were developed to screen home care subjects, one for adults, one for infants and one for the elderly. Also different questionnaire items were developed to evaluate the control and self care ability of chronically ill subjects. After training in interview methods for 2 days, 39 interviewers visited individual households for interviews. As the results of the study showed that 14.1％ of adult subjects and 76.5% of infants and child were judged as having at least one criterion related to home care need, 15.69% of adults and 53% of elderly had at least one chronic illness. The most prevalent chronic illnesses were hypertension, skeletal-neurological disease and diabetes. The prevalence of subjects with home care needs were, those with poor health care behavior(8.89%), with health-re-lated educational needs(8.71%), with poor recovery or control of disease (3.52%), and with poor social support and inadequate family resources(3.19%). There were only 0.3%, 0.37%, 0.11% who were discharged patients, patients with medical devices, or newborns respectively. Thus, the largest home care client group were those who need direct health care and health education. Seventy five percent of the subjects responded that they were willing to use and pay for home care service if it is offered in the future. It is suggested that recently discharged patients and patients with special medical devices can be cared for by hospital based home care nurses, but other home care clients can be cared for by com-munity based home care nurses.

On December 31, 2018, an incident occurred where a doctor was attacked and killed by a patient carrying a lethal weapon in the outpatients' clinic of the psychiatric department of a tertiary general hospital. The suspect was diagnosed with bipolar affective disorder (manic depressive disorder) and has been hospitalized and cared for in the psychiatric ward of this hospital. This incident illustrates the necessity of more active cures and therapeutic intervention for mental patients with intellectual developmental disorders who require treatment considering the fact that a radical outcome has been caused by such a patient. However, on the other hand, there is also a need for an approach and analysis from the perspective of crime prevention for all medical departments. The reason for this is that even a tertiary general hospital equipped with the largest human resources, medical devices, facilities, and so forth, is susceptible to violence. As for illegal actions perpetrated against health and medical service personnel in medical institutions, such as verbal abuse, assault, injury, etc. there have neither been understanding shown for the current extent of damage in detail, nor discussions of active institutional improvement related to the seriousness of the act. It can be said that violence in the field of medical treatment is a realm requiring serious discussion and appropriate remedial actions. This is because when such incidents take place, if a patient who is supposed to get treatment from the damaged health care provider is in an urgent situation or on the waiting list of serious cases, he or she could suffer serious damage caused by deprivation of treatment opportunity, or secondary damage might be caused to the patient and/or a guardian who can hardly have an opportunity to take action. Accordingly, in this review, we would like to help create the necessary conditions for both health and medical service personnel and patients/guardians, respectively, to provide and receive medical treatment in a more secure environment. Therefore, objective assessment of the institution and issues relating to this aforementioned incident and general cases of violence occurring in medical institutions, and by suggesting legal and institutional improvements and solutions.

By converting movable indirect mass chest X-ray devices for vehicles into digital systems and upgrading it to share information with the hospital's medical image information system, excellencies have been confirmed as a result of installing and running this type of system and are listed hereinafter. 1. Upgrading analog systems, such as indirect mass chest X-ray devices dependent on printed film, to digital systems allows them to be run and managed much more efficiently, contributing to the increase in the stability and the efficiency of the system. 2. Unlike existing images, communication based on DICOM standards allow images to be compatible with the hospital's outer and inner network PACS systems, extending the scope of the radiation departments information system. 3. Assuming chest-exclusive indirect mass chest X-rays, a linked development of CAD (Computer Aided Diagnosis, Detector) becomes possible. 4. By applying wireless Internet, Web-PACS for movable indirect mass chest X-ray devices for vehicles will become possible. Research in these fields must continue and if the superior image quality and convenience of digital systems are confirmed, I believe that the conversion of systems still dependent on analog images to modernized digital systems is a must.

Purpose : This study was designed to compare the easiness and speed of insertion of three supraglottic airway devices(SADs) in a manikin setting. Methods : Three different SADs - Laryngeal Mask Classic(cLMA), I-gel and Streamlined Liner of the Pharynx Airway(SLIPA) were applied. One hundred and nineteen paramedical students with(group H) or without (group L) previous airway experience were taught brief manikin training about the use of the cLMA, I-gel and SLIPA. The students inserted each device in a randomized order. Time to effective ventilation was recorded in seconds from holding the device to the first chest inflation. Success was determined as adequate chest wall movement. Results : The insertion attempts were lesser in I-gel($1.00{\pm}0.00$) and SLIPA($1.05{\pm}0.27$) than cLMA($1.16{\pm}0.41$, p<.05). The shortest time to insertion was recorded for I-gel($10.5{\pm}3.0sec$), followed by the SLIPA($12.9{\pm}4.5sec$) and cLMA($19.6{\pm}4.1sec$, p<.05). There were no significant differences in the insertion attempts and insertion time of I-gel between group L and group H. But in cLMA, longer insertion time and more insertion attempts were recorded in group L than group H. Conclusion : Both I-gel and SLIPA were superior to cLMA in the easiness and speed of insertion. Even in novice students, I-gel showed an excellent result in a manikin.
