본 논문에서는 컴퓨터 단층활영(CT)을 통해 발생되는 방사선 노출량의 관리를 위한 시스템의 소프트웨어 설계를 제안한다. 방사선 피폭량은 환자의 각 신체 부위별로 민감성의 차이에 따라 다르기 때문에 방사선의 노출량을 관리할 수 있게 되면 결과적으로 환자의 방사선 피폭량을 추정할 수 있다. 최근 일본 원전의 방사선 누출 사건이 국제적으로 뉴스가 되었고 원전 뿐 만아니라 의료용 방사선 피폭까지 폭넓게 관심이 커지고 있다. 현재 방사선 안전관리는 방사선 관계 종사자에 대해서만 관리되고 있지만, 이제는 환자에 대한 피폭 관리까지 요구되고 있다. 우리나라에서 방사선을 이용한 검사와 시술이 증가하여 이에 따른 의료 피폭이 증가하였으나 의료 기관에서는 환자에게 가해지는 방사선 피폭 수치를 알지 못하는 실정이다. 따라서 의료 기관에서 환자의 방사선 피폭을 관리할 수 있는 시스템이 필요하다. 본 논문에서는 의료 기관에서 방사선을 이용하는 대표적인 촬영 도구인 CT의 방사선 노출량을 관리할 수 있는 소프트웨어 설계를 제시한다. 방사선의 노출량을 확인하고 선량의 한도를 설정함으로써 환자의 의료 피폭량을 최적화 하는데 도움이 되고자 한다.

The purpose of this study is to measure the resource use of the elderly in long-term care services and to examine the effects of patient and facility characteristics on their use of resources. The data were collected from 510 old people over sixty years of age, residing in five long-term care hospitals and two skilled nursing homes during the period between December 1, 2000 and February 28, 2001. For a full sample, when the first level of RUG(Resource Use Group)-III categories were employed as the proxy of patient severity, facility characteristics, such as location, size and ownership, have large effects on the resource use measured by service intensity, whereas patient characteristics such as severity have little or no effect. The resource use is significantly high if the facility: (1) is located in rural areas (gun): (2) has mare than 200 beds; (3) is a long-term care hospital; (4) is private; and (5) has a low percentage of medical aid patients. The analysis of the resource use in each RUG-III categories, for which ADL(Ability of Daily Living) were employed as the prosy of patient severity, shows a similar result. The loose relationship between the needs of residents and the resource use seems to be closely associated with the ineffective reimbursement system for providers. The current reimbursement system has no provision for quality improvement and reimburses facilities simply according to their types: fee-for-service for long-term care hospitals, and monthly-flat-rate or full-coverage-national-aid for skilled nursing facilities. It will be necessary to develop a more reasonable reimbursement system that takes patient's severity into account and gives incentives for long-term care providers to offer cost-effective services.

Purpose : the management of University Hospital is being challenged in maintenance of reasonable level of income and high ranked reputation by domestic competition with each other and emergence of enterprised owned hospitals. It is imperative that University Hospitals have to make management for patient satisfaction. Furthermore, increased patient's requirement for qualified hospital services (quality assurance) and low-estimated service fee also repress the hospital management condition as well as medical markets open following with Urguay Connection. Due to these unforable conditions surrounding hospital management, -University Hospitals are being pressed to seek improved management strategies. To develope the strategies, we need to have basic understanding about the problems on hospital management and detail information for various patient's requirement. Methods: For this study, we have analysed out-patients from five different University Hospitals located in Seoul, Korea. To obtain the data, we have carried out personal interviews with patients who patients who visit the Out-Patient Clinics of five different University Hospitals using a previously prepared questionnaire. Result: Around 65.7 percent of the visits to University Hospitals were indwelt in the vicinity of 1 hour and motuvation of visiting University Hospital was expending high wuality medical csre in 49.3 percent. The 79.3 percent of the patients have experienced inconvenience during medical care in University Hospital. The most inconvenient condition was waiting for doctors. The 57.2 percent of total patient have experienced rudness. The most rudness condition was registration and receipt desk in 44.4 percent. Patient expect that doctors working in University Hospitals as professors have high and updated medical knowledge(50.4%) and University Hospitals have a high quality medical care system(79.4%). The patient satisfaction was relatively low in 61.1 percent of total patient and revealed high frequency of again visit University Hospital in satisfaction group. Comparison of interhospital analytical study showed quite difference on various problems. Conclusion: Almost patients who visit to Out-Patient Clinic of University Hospital havevisiting motivation to high quality medical care. University Hospitals have several different unsatisfactorial factors and revealed different degree of patient satisfaction. In a future day, University Hospitals have to make use of another University Hospital's merits for approach of Benchmarking and also should be studied decision factors of patient satisfaction and interhospital difference of them.

Renal injuries occur in more than 10% of patients who sustain blunt abdominal injuries. Non-operative management (NOM) is the established treatment strategy for lowgrade (I-III) renal injuries. However, despite some evidence that NOM can be successfully applied to high-grade (IV, V) renal injuries, it remains unclear whether NOM is appropriate in such cases. The authors report two cases of high-grade renal injuries that underwent NOM after embolization in a hybrid emergency room (ER) system with a 24/7 in-house interventional radiology (IR) team. A 29-year-old male visited Wonkwang University Hospital Regional Trauma Center complaining of right abdominal pain after being hit by a rope. Computed tomography (CT) was performed 16 minutes after arrival, and the CT scan indicated a grade V right renal injury. Arterial embolization was initiated within 31 minutes of presentation. A 56-year-old male was transferred to Wonkwang University Hospital Regional Trauma Center with a complaint of right flank pain. He had initially presented to a nearby hospital after falling from a 3-m height. Thanks to the key CT images sent from the previous hospital prior to the patient's arrival, angiography was performed within 8 minutes of the patient's arrival and arterial embolization was completed within 25 minutes. Both patients were treated successfully through NOM with angioembolization and preserved kidneys. Hematoma in the first patient and urinoma in the second patient resolved with percutaneous catheter drainage. The authors believe that the hybrid ER system with an in-house IR team could contribute to NOM and kidney preservation even in high-grade renal injuries.

The blood bank is a field of clinical pathology which requires the most accuratemaintenanceofrecording. Because the mistake in it is directly related to a patient's life. So, the computerization of the blood bank is urgent to maintain a log blook arid to compare the patient's current data with past result. We developed the blood bank management program using 32 bit minicomputer. This is composed of 4 parts; a management of routine test result, special test result, the blood issue and statistics. The management of routine test result handles the patient's information and blood typing and compares above results with the past one of same patient. The management of special test result are for special immunohematologic tests like an irregular antibody, Coombs' test, and etc. Blood issue part records the type of the blood bag, component, and the name of issuer. Statistic part are made to get statistics of each day and each month by the blood type, and the type the blood component. The program is secured by the maintenance of operator's operation history and thu provision of the security code to each operator, without which no one can enter the system and after the content. So the stability and reliability of the data is obtained. This program will be upgraded for bar-code using system in the near future.

Background: The costliness index (CI) is an index that is used in various ways to improve the quality of medical care and the management of appropriate treatment in medical institutions. However, the current calculation method for CI has a limitation in reflecting the actual medical cost of the patient unit because the outpatient and inpatient costs are evaluated separately. It is desirable to calculate the CI by integrating the medical cost into the episode unit. Methods: We developed an episode-based CI method using the episode classification system of the Centers for Medicare and Medicaid Services to the National Inpatient Sample data in Korea, which can integrate the admission and ambulatory care cost to episode unit. Additionally, we compared our new method with the previous method. Results: In some episodes, the correlation between previous and episode-based CI was low, and the proportion of outpatient treatment costs in total cost and readmission rates are high. As a result of regression analysis, it is possible that the level of total medical costs of the patient unit in low volume medical institute and rural area has been underestimated. Conclusion: High proportion of outpatient treatment cost in total medical cost means that some medical institutions may have provided medical services in the ambulatory care that are ancillary to inpatient treatment. In addition, a high readmission rate indicates insufficient treatment service for inpatients, which means that previous CI may not accurately reflect actual patient-based treatment costs. Therefore, an integrated patient-unit classification system which can be used as a more effective CI indicator is needed.
