The biological effects for the use of hypertherinla to treat malignant tumors has been well studied and encouraging clinical results have been reported. However, the engineering and technical aspects of hyperthermia for the deepseated tumors has not been satisfactory. We have developed the FF capacitive hyperthermia device(GHT RF8)by cooporation with Yonsei Cancer Center and Green Cross Medical Equipment Corporation. It was composed with 8.10 MHz RF generator, capacitive electrode, matching system, cooling system, temperature measuring thermocouples and control PC computer. We have measured the temperature and thermal distribution in agar phantom, animals and human tumors.

Nebulizer is designed to atomize medicinal fluid for patient with small particles(0.5-$5{\mu}m$) and also able to deliver particles from devices to the lungs when patient inhales air. Several particle size measurements are currently used to size aerosol particles. The most commonly used test is the cascade impactor method in as a standard. But, other methods for comparative particle size distribution data such as the particle size range and reproducibility are acceptable. Therefore, in this study a new test methode is suggested for nonventilatory nebulizer evaluation equipment.

J2ME service technology has advantage that can embody independent and, more soft system in DICOM 3.0 and medicine reflex administration server, client′s OS that is medical treatment reflex standard in radio Internet. Also, intranet that do web based spread, and develop by system that can alternate existent client-server structure rapidly. Specialty, possibility of improvement is much because is connecting being limited in internet environment that medical equipment and information system of various kinds of machine are wire in medical institution and so on. Because do medical treatment reflex transmission module development applying DICOM technology and filtering techniques of "m-PACS" In this research, existence, by interlock in radio usable Mobile reflex conversion system design and embody. That is, patient′s information which is stored to various systems to be transmited and can give big help in medical examination and treatment to reflex client without being wooed doctor′s interpretation result and so on in place through environment to be radish tentacle bar see.

In this study, we present the commissioning and validation results of a dedicated scanning nozzle. The dedicated scanning nozzle is installed in one of the two gantry treatment rooms at Samsung Proton Therapy Center. Following a successful completion of the acceptance test, the commissioning process including the beam data measurement for treatment planning system has been conducted. Extended measurements have been conducted as a validation of the clinical performance of the nozzle and various quality assurance protocols have been prepared.

Recently, our country is caused with economic growth and development and city intensive brazier being caused by industrial accident, crime accident and suicide of traffic facility, it is caused by with Western dietary life and the emergency patient is to an increase tendency. And the life increases with medical development and the medical emergency demand of the old people are increasing. Approximately 80% of the patients are non-emergent patients who receive ambulatory care and the rest 20% of the patients are serio us- emergent patients Emergency patients because non-strategy it is doing with function as imported medical treatment and provides, equipment, the operation is being impossible with manpower tribal etc.

This paper focuses on lossy medical image compression methods for medical images that operate on two-dimensional(2D) integer wavelet transform. We offer an application of the Set Partitioning in Hierarchical Trees(SPIHT) algorithm to medical images, using a 2D wavelet decomposition and a 2D spatial dependence tree. The wavelet decomposition is accomplished with integer wavelet filters implemented with the lifting method, where careful scaling and truncations keep the integer precision small and the transform unitary. We have tested our encoder on medical images using different integer filters. Results show that our algorithm with certain filters performs as well and is sometimes better lossy coding using 2D integer wavelet transforms on medical images.

Medical lasers have been widely used for various diseases. Despite the notable benefits, lasers could cause several complications such as skin burn, eye injury, airway fire, and so on. These accidents may occur not only with patients, users of the laser, or laser handlers but also to people passing in front of the laser treatment room. Although there is a risk associated with the laser, most of them can be prevented through good training, use of proper protection equipment, and ensuring the safe operation of the laser at all times. Due to the increasing use of lasers and the growing interest in their use, medical institutions should particularly emphasize the safe use of lasers and introduce systems for laser safety.

The coronavirus disease 2019 (COVID-19) pandemic has taken a toll on human lives and health systems worldwide and is still affecting all medical practices years later. In particular, much medical staff had to sacrifice in areas where the medical system was overloaded in the early stages of the outbreak and the resulting shortage of medical resources. In the future, another pandemic disease seems to emerge, which should threaten otolaryngologists inevitably. It is necessary to understand viral aerosolization and practice recommendations for COVID-19. These can guarantee the most effective treatment for the patients during the pandemic and protect the safety of our medical staff and patients.

The purpose of this study was to provide the basic data for improvement of Emergency Medical Service System in Kwangju. The EMSS can be defined as the complete chain of human and physical resources that provides patient care in cases of sudden illness and injury. To provide effective emergency care through the EMSS in a region, the issue of training especially as it relates to EMT in EMSS delivery is more important than emergency medical equipment and facilities for pre-hospital emergency care. The transport of emergency medical patients carried out almost by 119 Emergency Medical Services. But out of all the employees at 119 EMS only 19.0% have graduated with a major in Emergency Medical Technology. It would seem prudent then that the graduates of EMT programs should gradually replace employees working at 119 EMS that do not have an EMT degree to ensure the best possible pre-hospital care for emergency medical patients. Therefore it can be expected that in the future there should an enormous demand for qualified EMT professionals to meet the growing needs for a superior level of emergency medical care for civilian.

Various types of high-precision radiotherapy, such as intensity-modulated radiation therapy (IMRT), tomotherapy (Tomo), and stereotactic body radiation therapy have been available since 1997. After being covered by insurance in 2015, the number of IMRT cases rapidly increased 18-fold from 2011 to 2018 in Korea. IMRT, which uses a high-beam irradiation monitor unit, requires higher shielding conditions than conventional radiation treatments. However, to date, research on the shielding of facilities using IMRT and the current understanding of its status are insufficient, and detailed safety regulation procedures have not been established. This study investigated the recommended criteria for the shielding evaluation of facilities using medical linear accelerators (LINACs), including 1) the current status of safety management regulations and systems in domestic and international facilities using medical LINACs and 2) the current status of the recommended standards for safety management in domestic and international facilities using medical LINACs. It is necessary to develop and introduce a safety management system for facilities using LINACs for clinical applications that is suitable for the domestic medical environment and corresponds to the safety management systems for LINACs used overseas.
