The supply of medical services using high-priced medical equipment is increasing due to the medicalization of medical science. The level of medical knowledge of medical consumers and the ability to select medical institutions are required to provide high quality medical services because of the popularization of medical information. As the attitudes of medical consumers toward medical institutions change, medical institutions also need to change their perception to improve customer satisfaction. The purpose of this study is to analyze the difference of medical service satisfaction according to the medical knowledge about the utility of PET / CT in order to change the consciousness structure of medical service. The results of this study showed that both medical satisfaction and environmental satisfaction were high in those who had medical knowledge about their own illness and the usefulness of PET / CT. Therefore, medical institutions will need a practical medical service countermeasures to provide medical information by noticing the changes in perception of the medical knowledge of medical consumers, rather than providing formal medical services.

This study suggests a Healthcare System for elderly and disabled who have mobility impairment and use a wheelchair for long time. Seating long time in a wheelchair without reducing pressure causes high risk of developing pressure sores. Pressure sores come with great deal of pain and often lead to develop complication. Not only it takes time and effort to treat pressure sores but also increases medical expenses. Therefore, we will develop a device to help to prevent pressure sores by measuring pressure distribution while seating in a wheelchair and wirelessly send information to user device to check pressure distribution in real time. The equipment to measure body pressure is composed of FSR sitting mat which is a sensor measuring part and an user terminal which is a monitoring part. The designed mat is matrix formed FSR sensor to measure pressure. The sensor send measured data to the controller which is connected to the end of the mat, and then the collected data are sent to an user terminal through a bluetooth. Developing a pressure monitoring system will help to prevent those who have mobility impairment to manage pressure sores and furthermore relieve their burden of medical expenses.

The PhotoAcoustic Microscopy (PAM) has been proved to be a useful tool for biological and medical applications due to its high spatial and contrast resolution. PAM is based on transmission of laser pulses and reception of PA signals. Since the strength of PA signals is generally low, not only are high-performance optical and acoustic modules required, but high-performance electronics for imaging are also particularly needed for high-quality PAM imaging. Most PAM systems are implemented with a combination of several pieces of equipment commercially available to receive, amplify, enhance, and digitize PA signals. To this end, PAM systems are inevitably bulky and not optimal because general purpose equipment is used. This paper reports a PA signal receiving system recently developed to attain the capability of improved Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) of PAM images; the main module of this system is a low noise, wideband signal receiver that consists of two low-noise amplifiers, two variable gain amplifiers, analog filters, an Analog to Digital Converter (ADC), and control logic. From phantom imaging experiments, it was found that the developed system can improve SNR by 6.7 dB and CNR by 3 dB, compared to a combination of several pieces of commercially available equipment.

A radiographer is a job in charge of diagnostic imaging equipment, and must contribute to the promotion of public health by suggesting an appropriate level of work. To this end, we intend to present an appropriate level of work through evaluation of human harm according to work, statistical evaluation through questionnaires, and domestic and international trends. In the case of human harm evaluation, considering radiation exposure, 42.6%, shield work, 69.7%, and in the case of magnetic resonance imaging, the maximum length of stay in the examination room should be adjusted to 15 minutes and not exceed 30 times. According to the survey statistics, it was confirmed that the physical and mental burden increased due to the high workload and difficulty compared to working hours. Based on domestic and international trends, it is necessary to adjust the examination standards for domestic radiographers to 36.8% to promote national health through qualitative improvement of radiological examinations. something to do.

Purpose: The purpose of this paper is to provide basic data in order to systemize the management of demand and supply of radiologic technicians, to pursue a fair regional distribution of educational institutions, and furthermore to keep reasonable medical treatment and fee. This research was carried out through the investigation of radiologic equipments and technicians according to the distribution of the population. Materials and Methods: We compared and analyzed the correlation between regional population, the number of clinics and hospitals, the number of medical imaging devices, and the number of radiologists and radiologic technicians in 5 cities without "Gu" administrative units in 2008. Results: 27,317 radiologic technicians have been produced since the administration of the national qualifying exam for radiologic technicians. About 18,000 radiologic technicians are currently working. There are 39 colleges or universities with Departments of Radiology and the admission quota is 2,120 students excluding one college. The ratio of radiologic equipments to radiologic technicians is 2.6 to 1. Conclusion: There is a dilemma in which some radiologic technicians fail to find appropriate jobs while some clinics or hospitals are in need of radiologic technicians. This dilemma is due to unreasonable regional discrepancies in pay system and welfare situation, and excessive profit-oriented recruiting system of clinics and hospitals. The increase of students of Radiologic Departments and approval of additional departments will end up with producing superfluous high academic degree holders, which is on the contrary to the government policy to produce more job opportunities. So the policy of increasing Radiologic Departments should be reconsidered.
