본 연구에서는 2011년1월1일부터 2011년 6월 30일까지 6개월 동안 대학병원 응급실로 방문하여 내과로 입원한 환자 889명을 조사대상으로 응급의료센터에 방문한 환자의 주호소와 주진단에 대한 분포를 확인하고, 기존의 질병분류 방법인 ICD와 일차 진료를 세부 분류하는 방법인 ICPC를 비교하고자 하였다. 분석방법으로는 환자들의 인구통계학적인 측면을 살펴보기 위해 빈도분석이 시행되었으며, ICD와 ICPC에 따른 주호소 분포를 알아보기 위한 교차분석을 시행하였다. 다음과 같이 분석을 시행한 결과 주증상중 Abdominal pain이 17.7%, dyspnea가 13.5%, Fever가 12.5% haematemesis가 9.8%로 주로 일차의료에서 사용되는 주호소 증상이 전체의 54.5%를 차지하는 것으로 나타나 응급의료센터에서 일차 진료 분류법을 사용하는데 적합한 것으로 예상되었다. 또한 진단명중 abdominal pain의 경우 ICD에서 R10으로 116(18.7%)명이 분류되었지만 ICPC에서는 epigastric(11.5%)과 general(5.8%)로 나뉘어 분류되어 세분화 되는 것으로 나타났다. 즉, 현재 병원에서 시행되고 있는 ICD 분류법 보다는 일차 진료 분석에 초점이 맞춰진 ICPC 분류법이 좀 더 세분된 환자분류에 용이하다는 것을 알 수 있다. 비록 본 조사에 사용된 자료가 1개 병원에 그치고 있어서 자료의 대표성이 확보되기는 어렵지만, ICPC가 응급의료에 있어 분류가 가능하고 기존의 분류법 보다 세분된 환자분류가 용이하다는 점에서 그 의의가 있다.

한의학은 진단 및 치료에 있어 뛰어난 우수성을 가지고 있음에도 불구하고 서양의학에 비해 선호도가 떨어진다. 이는 질병 진단에 있어 객관적인 진단 결과를 제공해 주는 서양의학에 비해 한의학은 임상의의 직관에 의존하고 있기 때문이다. 따라서 한방 임상의들의 직관을 객관화하여 기기로 구현 한다면 한방에 대한 선호도 상승 및 한의학의 세계 시장 진출도 크게 증대할 것으로 여겨진다. 특히 한의학의 진단법 중 가장 뛰어난 진단법으로 평가되는 망진의 경우 다른 진단법에 비해 관련 연구가 거의 이루어 지지 않고 있다. 이는 망진의 가장 중요한 요소인 찰색에 있어 실제 색의 분석을 위한 디지털 기기에서의 색 분석 기준이 없기 때문이다. 이를 위해 본 논문에서는 찰색을 기기로 구현하기 위한 절대적인 색 기준의 설정을 제시하고자 한다. 따라서 색 분석을 위해 여러 가지 디지털 색체계를 비교 분석하여 찰색을 위해 어느 디지털 색체계가 가장 효율적인 색 체계인지를 제시하고자 한다. 아울러 실험 환경의 차이에 따라 발생할 수 있는 변수를 최대한 줄이기 위한 실험 환경 및 조건에 대한 표준화를 제안하고자 한다.

This study focused on the method of interpreting Moire's topography. There has been no standard of interpretation which informed, this study, The conclusions arc as follows: Miore's image closed contour lines which is consisted of points. These points in one contour have the same distances from the screen to the patient's back. Moire's index means the number of contour gaps from symmetrical point of a specific point with the axis of central line. The number of contours which pass the median line means the degree of antero-posterior curvature.

Compared with the earlier technique of dual photon absorptiometry (DPA) using $^{153}Gd$ radionuclide source, dual energy X-ray absorptiometry (DXA) has advantages of higher precision, accuracy and shorter scanning time. Despite the change from DPA to DPX, the nuclear medicine physicians has remained one of major suplier of this service due to long-standing use of DPA. Among many kinds of bone densitometries, DXA is the "gold standard" for the noninvasive diagnosis of osteoporosis. Especially there is no role for peripheral devices in the monitoring of patients on therapy. But, there are some areas of controversy related to the application of DXA, such as proper site of measurement, accurate interpritation, appropriate use of T-score, and the reference population young database. And the accuracy, precision, and quality control issues relating to bone density measurement are important subjects. To address these issues, the International Society for Clinical Densitometry (ISCD) has convened two Position Development Conferences and addressed official positions. This review deals the key elements of ISCD position paper and other important issues on the management of bone densitometry.

In oriental medicine, diagnostic method was the four examination(四診) which was composed of inspection(望診), inquiring(問診), listening and smelling(聞診), palpation(切診). Inspection of skin color(望色) indicated the observation of patient's complexion(色診). In oriental medical theory, complexion of face was related to meridians(經絡) and zang-fu(贓腑). The change of complexion was reflected the ups and downs of qi(氣) and blood(血), the relative seriousness of an illness. especially, observation of complexion was essential in children, because of diagnostic difficulty and positive change according to each disease. The purpose of this study was to construct for standard measurement and invent for computerizing diagnostic system which was based on observation of complexion. It was objectively measured complexion using spectrophotometer and chroma meter. Measurement of complexion should make an offer the index of diagnosis.

Coronary computed tomography angiography (CCTA) is routinely used for anatomical assessment of coronary artery disease (CAD). However, invasive measurement of fractional flow reserve (FFR) is the current gold standard for the diagnosis of hemodynamically significant CAD. CT-derived FFRCT and CT perfusion are two emerging techniques that can provide a functional assessment of CAD for risk stratification and clinical decision making. Several clinical studies have shown that the diagnostic performance of concomitant CCTA and functional CT assessment for detecting hemodynamically significant CAD is at least non-inferior to that of other routinely used imaging modalities. This article aims to review the current clinical evidence and recent developments in functional CT techniques.

Chronic invasive aspergillosis is a life-threatening disease, especially in immunocompromised patients. The diagnosis and treatment of tracheal aspergillosis (TA) are challenging because of its rarity and nonspecific clinical presentations. The treatment standard of TA has been medical treatment like other forms of invasive aspergillosis, but patients with medically resistant TA require surgical intervention. We demonstrated a successful surgical outcome of chronic invasive TA in a 16-year-old patient with immunocompromised status related to acute myelocytic leukemia.

Cushing syndrome (CS) is rare in pregnancy, and few cases have been reported to date. Women with untreated CS rarely become pregnant because of the ovulatory dysfunction induced by hypercortisolism. It is difficult to diagnose CS in pregnancy because of its very low incidence, the overlap between the clinical signs of hypercortisolism and the physiological changes that occur during pregnancy and the changes in hypothalamus-pituitary-adrenal axis activity that occur during pregnancy and limit the value of standard diagnostic testing. However, CS in pregnancy is associated with poor maternal and fetal outcomes; therefore, its early diagnosis and treatment are important. Here, we report two patients with CS that was not diagnosed during pregnancy, in whom maternal and fetal morbidity developed because of hypercortisolism.

A medical teleconferencing and medical image transmision system has been developed for diagnosis of the medical images between the medical doctors who are far away. The medical teleconferencing system transmits the voice and image of the doctors using the video and audio capture boards. The medical image transmission system software uses the medical image standard DICOM 3.0 for the future expansibility and the open system interconectivity. The medical images usually use CR images.

Retinopathy of prematurity (ROP) is a major cause of blindness that affects premature infants. With advances in neonatology, ROP is likely to emerge as the most serious problem of vision loss in children even in developed countries; such a situation could be called the third epidemic of ROP. However, controversy and uncertainty still surround favorable outcomes of ROP. For successfully controlling ROP, timely and accurate screening is crucial because early treatment leads to favorable outcomes. Standard guidelines, including ROP classification, have provided satisfactory instructions for the screening and treatment of ROP. To improve the structural and functional outcomes of ROP, optimizing the timing of surgical interventions including cryotherapy, laser-photocoagulation, encircling, and vitrectomy is essential; these interventions can prevent the sequelae of ROP. It is essential for the neonatologist and the ophthalmologist to cooperate extensively for the successful treatment of ROP.
