The rise in chronic disease not only has a negative effect on people's lives, but it also increases the cost of medical care owing to the increased usage of medical care as health and medical technology improves, life expectancy rises, and rapid population ageing. In such context, this study examined the difference in the disease cost of hypertension according to demographic information and the effect of the initial diagnosis age and treatment period on the cost. This study used the Korean Health Panel Survey from 2010 to 2017, and selected subjects based on health insurance beneficiaries between the ages of 30 and under 80. With the selected data, the direct and indirect costs of disease loss were calculated according to the cost of illness approach, and we constructed a disease-loss ratio cohort considering the age of diagnosis and time of treatment for hypertension. From the results of the study, the annual cost of disease loss for hypertensive patients differed by gender by 110,107 won, and it was found that the cost increased by 1.8 times as the treatment time increased. In addition, when comparing disease loss ratios between the same age groups, it was found that the disease loss ratios between those in their 60s and 70s were affected by treatment time. This study confirmed that hypertension significantly affects the cost of the disease, and not only requires early diagnosis and management, but also preventive efforts to lower the incidence of hypertensive disease must be strengthened.

Purpose: There is a growing concern for the cost management of medical institutions. The purpose of this study was to estimate Activity-Based Costing (ABC) for dental implant cost. ABC refers to allocating resources or cost based on the activities of services. Materials and methods: A dental institution located in the metropolitan area was selected in this study. The tax accounting data of the institution were utilized to confirm total cost, and the institution was asked to make out clinical activities to figure out what activities were carried out. The direct cost and indirect cost for dental implant were separately estimated, and cost driver was analyzed to estimate the indirect cost accurately. Results: The rates of the direct and indirect cost respectively stood at 35.8 and 49.5 percent. The cost for a dental implant was found to be approximately 1,579 won, and the cost of prosthetic surgery and treatment that included implant surgery accounted for the largest portion of the cost, which was 470 thousand won (30%). And the weight of training and education on dentistry was relatively higher than that of the other kinds of treatment. Conclusion: In order to ensure accurate and scientific costing for dental implant, not only direct medical procedure but every pre- and post-procedure activity should fully be taken into account. Pre-activities, post-activities, education and training are included in the indirect cost, but all these activities are mandatory and associated with the quality of treatment and the satisfaction level of patients.

혈중 산소농도는 의료 분야에 기초적인 간으로 쓰이고, 이의 측정법은 오랜 역사를 가지고 있다. 현재까지 인체의 혈액 중 산소 포화도는 혈액을 직접 추출하여 조사할 수 있었으나, 이러한 직접추출 방법은 생리학적인 제조건의 변화에 따라 변할 수 있어서, 인공심장 등의 응용으로 사용될 때에는 신속한 정보를 알아야 하므로 부적합하다. 본 연구에서는 비추출식 산소 포화도를 광학적인 방법으로 연구하는데 필요한 자료 조사 및 기본 이론 분석에 있다.

The rapid aging is increasing as the shortage of medical facilities and the resulting of decline in the quality of public health. In order to ease the burden of rising medical expenses, advanced medical institutions are expanding their remote medical care to lower the cost of services. U-healthcare detects the changes in physical and chemical phenomena occurring in the human body and converts them into electrical signals that can be processed and feeds back to the results through analytical and visualization processes to select only the desired information from the measured signals. The service is provided through a process of providing an alarm to a user. However, traditional biometric methods of attaching sensors directly to the body can be annoying and rejected in daily life. Therefore, there is a need for a method of continuously measuring biometric information without causing inconvenience to daily life. In this paper, we propose an IR-UWB-based non-contact and non-responsive respiratory measurement system that can continuously monitor biological information without any inconveniences to daily life.

Medical images are an effective means to identity medical abnormalities.. Patients typically have medical images taken at different clinics during lifetime, and they often wish to have second interpretation on medical images showing substantial diseases. At present, since personal medical images are distributed to multiple clinics, there is a bit discomfort that patients directly bring their images by hands to get the second interpretation from another physician. With these two motivations, we design a cloud service for archiving medical images and interpreting medical images by physicians. We present the design and implementation of the service, and show its practical value as low-cost personal healthcare service. By using the service, patients can retrieve and review their medical images anytime and have a convenience of acquiring second opinions on their medical images at low-cost without visiting a clinic.

In the context of the COVID-19 era, due to the serious epidemic and heavy workload, medical staff often work overtime. The frequency of overtime work is directly related to organizational trust, so the impact of overtime work is of high importance to medical staff. This study focuses on the role of overtime work and validates the level of organizational trust among healthcare workers. The mediating effect of personal achievement as a mediator between overtime work and organizational trust was also explored. According to the results, both voluntary overtime and inoluntary overtime of medical staff have a positive impact on organizational trust. The results also suggest that personal accomplishment has a mediating effect between overtime work and organizational trust. This study focuses on exploring the impact of medical staff overtime work on organizational trust and proposes options for improving organizational trust among medical staff.

최근 상압 저온 플라즈마에서 발생되는 UV와 화학적 활성종들을 이용한 체내 조직 분해 처리, 피부 및 혈관 표면 처리, 대기 및 액체 정화 처리 등의 생체 의료적 응용이 활발하게 연구되고 있다. 이러한 플라즈마에서는 처리 대상 외의 생체 조직의 손상을 최소화 할 수 있는 기술이 필요하며, 이 조건이 확보된 상태에서 처리 목표 대상에 따른 플라즈마 특성, 즉 선택적 생성종 제어와 플라즈마 온도를 안정적으로 관리할 수 있어야 한다. 인체 내부 조직에 대하여 유효 활성종 등의 직접적인 작용이 필요할 경우 밀리미터 크기 이하의 미세침습성 플라즈마를 활용하게 된다. 이 경우 방전 특성을 간접적으로만 관측 가능하여 주변 조직과 플라즈마 간의 상호 영향 등이 고려되어야 하므로 직접적인 관측이 가능한 인체 외부에서 발생된 플라즈마에 비해서 더욱 정교한 제어가 필요하다. 본 연구에서는 미세 침습성 플라즈마의 발생 메커니즘 및 특성 분석을 수행하여 척추 디스크 탈출 치료 시술에 활용하기 위한 연구를 수행하였다. 처리 대상 조직으로의 접근 시 주변 조직의 손상을 막기 위하여 수 밀리미터 이하의 미세한 전극을 이용하였으며 전기 전도성을 띄는 인체 내부에서 절연공간의 확보를 위해 전극 표면에서 기포를 발생시켜 플라즈마 방전이 가능한 조건을 확보하였다. 또한 플라즈마 방전이 중단되거나 혹은 갑작스런 열 플라즈마로의 천이로 인해 생체에 심각한 열 손상을 초래하는 현상을 방지하기 위하여 발생 플라즈마와 주변 디스크간의 상호 영향을 통한 플라즈마의 동적인 특성 변화 및 안정적인 플라즈마 발생을 위한 조건을 도출하였다. 이를 실제 임상 실험에 활용한 결과를 소개하고 아울러 차세대 의료용 플라즈마 발생 장치 개발을 위한 플라즈마 학계의 관심을 이끌어 보고자 한다.

Our Constitution obliges the state to protect the health of the people, and the Medical Law, which embodied Constitution, sets out in detail the matters related to open the medical institution and one of them is to prohibit the operation of multiple medical institutions In the past, there was a provision stipulating the same purpose. But because the Supreme Court interpreted that several medical institutions could be opened if the medical treatment was not made at the additional medical instition which was opened in the another doctor,s license, multiple medical institutions could be opened and operated. However, some health care providers opened the several medical institutions to another doctor's license just by the excuse of the business management and then did illegal medical cares like the unfair luring of patients, overtreatment, and commition treatment for more profits. So, the health rights of the people came to be infringed on. Accordingly, lawmakers amended the Medical Law for medical personnel not to open and to operate more than one medical institution. As the amended medical law prohibited a medical personnel to open multiple medical institution, some medical personnels insisted that the amended medical law is unconstitutional under which they could not be able to open and operate medical institutions on based on free investment and bring out the benefits of network hospitals. But the regulation to prohibit multiple institutions does not apply only to a medical personnel. Many other experts like lawyer and pharmacist can open only one office under such a restriction. If the regulation goes out of force, the procedure that multiple medical institutions should be opened and operated in the capacity as a medical corporation or a non-profit corporation does not have to be followed. And we should keep in mind that the permission for medical personels to open multiple medical institutions could lead virtually to commercial hospital. If in the nation with a very low rate of public medical service, If only a few medical personnels with capital own many medical institutions and operate commercially them, this could cause a falling-off in quality of medical service, ultimately infringe on the health rights and the life right of the people.
