In Korea, Resource-Based Relative Value Scale (RBRVS) was developed in 1997 and introduced in 2001 for the alternative of Korean Medical Fee Schedule. The RBRVS measures physician resource inputs to construct relative values for services and procedures. The RBRVS, as an administered price system, would need to be updated periodically. Changes in practice costs and practice patterns, and the rapid evolution of technology will require that relative values be adjusted over time. The Relative Value Scale Update Committee (RUC) in Korean Medical Association (KMA) is under updating annual review and 5-year review of Korean Relative Value Scale (RVS). The Korean RVS is estimated less balanced and rational in general, and furthermore there was no update after base-line study. So, it is the reason why this update of RVS is important. We, rheumatologists, are specialists for rheumatic diseases and are unfamiliar and unconcerned with health care system and medical insurance fee schedule, but this attitude is not appropriate to improve our specialized medical situation. This article reviewed the history of Korean medical insurance, development and update procedure of Korean RVS, and the current insurance problems in rheumatic diseases briefly. In Korea, RVS of medical services including rheumatology is relatively less compensated than the other invasive and imaging services. Therefore, Korean RVS update should be changed to more balanced and reasonable one for the medical service including rheumatology.

N/A Objectives: To estimate the prevalence of rheumatoid factor(BF) positivity in adult Korean population and to investigate the association between viral hepatitis infection and rheumatoid factor positivity. Methods: The database from 21,907 subjects who visited general health screening center of Asan Medical Center during 1 year's period were surveyed. RF was tested using a commercial latex test kit(RapiTex® RF Test; Behringwerke). Results : 1) The prevalence of I4F was 2.9%(male 3.1%, female 2.7%) and increased along with the higher age groups. 2) The prevalence of HF in HBsAg(+) subjects was higher(13.3%) than that of RF in HBsAg(-) subjects(2.2%). 3) The prevalence of RF in anti-HCV(+) subjects was higher(6.1%) than that of BF in anti-HCV(-) subjects(2.8%). 4) HBsAg positivity was highly associated the presence of RF than age, anti-HCV, or abnormnl AST/ALT. Conclusion : The prevalence of RF in healthy Korean adults can be estimated as 3% and shows high association with hepatitis B and C virus infection.

Objective: The aim of our study was to define the prevalence, demographic data, selection of the medical services and disability of the patients with self-reported arthritis which were based on the data of National Health and Nutrition Survey (NHNS) conducted by Korea Institute for Health and Social Affairs (KIHASA) and Ministry of Health and Welfare in 1998. Methods: By a stratified multistage probability sampling method, 200 sample districts which consisted of total 13,523 households were selected all over the country. The investigation started with a basic household survey which was completed in 12,189 households with exclusion of non-kinship family. The Health Interview Survey was subdivided to 5 parts including the basic household survey (n=39,060), the diseases survey (n=26,448), and the disability survey (n=694). Results: An estimated 8.0% of Koreans had some form of self-reported arthritis in 1998 and this proportion was higher than that of other chronic medical conditions such as peptic ulcer disease, hypertension, and diabetes mellitus (DM) -7.0%, 4.5%, and 2.2%, respectively. Arthritis was more prevalent among people with female, increasing age, lower income (less than 500 thousand ₩ per month), lower educational attainment (less than 9 years), and lower standard of living. Especially, arthritis ranked first in prevalence as the cause of the chronic disease in the population aged over 45 years, with the prevalence rate of 22.6%. People with arthritis were more likely to report functional limitations such as activities of daily living (ADL) and instrumental activities of daily living (IADL) (5.4%), compared with people who had other musculoskeletal diseases, such as low back pain (3.8%), and herniated intervertebral disc (2.8%). The loss of productivity from arthritis was estimated to reach 0.25% of gross domestic product (GDP) amounts to ₩ 1,133 billion per year which was remarkably higher than that of cardiovascular diseases or cancers. Conclusion: Arthritis has a major impact on the health profile of our population. High burden of arthritis in our society should be considered as an important factor in planning health care services and setting research priorities.

Light-activated metal oxide gas sensors have been investigated in recent decades. Light illumination enhances the sensing attributes, including the operational temperature, sensitivity, and selectivity. Unfortunately, high operating temperature is a major problem for gas sensors because of the huge energy consumption. Therefore, the importance of light-activated room-temperature sensing has increased. This paper reviews recent light-activated sensors and their sensing mechanisms with a specific focus on metal oxide gas sensors. Studies use the outstanding ZnO and SnO<sub>2</sub> sensors to research photoactivation when illuminated by various sources such as ultraviolet (UV), halogen lamp, or monochromatic light. Photon induction generates electron-hole pairs that increase the number of adsorption sites of gas molecules and ions improving the sensor’s sensing properties.

Behcet`s disease can elicit serious vascular complications such as thrombophlebitis, arterial occlusion, and arterial aneurysm. The most common cause of death in Behcet`s disease is secondary to vascular complication. The treatment for abdominal aortic aneurysm which was frequently complicated by fatal rupture (60%) is mainly a surgical management. If surgical treatment is not possible due to various causes, alternative medical therapy such as immunosuppressives and steroid would be recommended. We report here the case of medically controlled abdominal aortic aneurysm in a 47-year-old patient with Behcet`s disease who refused to undergo surgical treatment. Immunosuppressive therapy and steroid could be an alternative treatment of aneurysmal manifestations in Behcet`s disease.

Primary antineutrophil cytoplasmic antibody (ANCA) associated vasculitides (AAV) constitute a group of small vessel vasculitides that includes Wegener`s granulomatosis, microscopic polyangiitis and Churg-Strauss syndrome. Recently, many in vitro and in vivo studies have highlighted the role of ANCA as the main pathophysiological factor in the development of AAV. Two remarkable studies on ANCA pathogenesis were recently reported. One study examined anti-lysosomal membrane protein-2, which supports the `shared epitope` theory. The other examined the neutrophil extracellular trap that is released by neutrophils primed by ANCA. Each disease of AAV shows a broad spectrum of the clinical features and severities, which makes it difficult to diagnose and treat them. Considerable effort has been made in the past decades to improve the treatment outcomes, reduce the incidence of relapse and avoid drug toxicity. This review describes the current understanding of AAV along with a few Korean reports.
