In total body irradiation (T81) for leukemia, we have a two methode. One is a AP (anterior-posterior) method and the other is a Lateral methode. Our hospital used lateral methode. T81 must consider about body contour, because of homogeneous dose distribution. For compensation about irregular body contour, we use compensator. For T81 treatment, we must be considered, accurate manufacture of compensator and accurate calculation of dose. We developed the automatic program for T81. This program accomplished for compensator design and dose calculation for irregular body. This program was developed for uses to use in a windows environment using the IDL language. In this program, it use energy data for each energy: TMR, output factor, inverse square law, spoiler, field size factor. This program reduces the error to happen due to the manual. As a development of program, we could decrease the time of treatment plan and care the patient accurately. 전신방사선조사(total body irradiation)는 크게 두 가지가 있는데 첫 번째는 전후 이문대향조사방법(anterior-posterlor total body irradiation)이고 두 번째는 좌우 이문대향조사방법(lateral total body irradiation)이다. 본 병원에서 시행 중인 방법은 환자의 좌우 이문대향조사방법으로서 환자의 측면에서 방사선이 조사되기 때문에 인체의 윤곽에 따른 방사선의 분포가 각 부분에 대해서 다르게 나타나게 된다. 전신 방사선 치료에서 보상체(Compensator)를 사용하여 몸 전체에 균일한 방사선 분포를 만들어내게 한다. 하지만 이런 보상체의 제작은 인체의 모든 부위에서의 수치, 각 부분의 깊이와 길이가 필요한데 특히 머리 부위와 다리 부위 수치에 대한 세밀한 고려가 중요시 되며 또한 조사되는 방사선량의 정확성이 요구된다. 본 연구에서는 기존에 수작업으로 각 부분을 계산하는 방법에서 방사선데이터 및 환자의 각 부분을 데이터화하여 윈도우 환경에서 사용이 용이한 전신방사선조사 계산 프로그램을 개발하였다. 개발된 프로그램은 보상체의 제작 및 방사선량을 계산할 수 있도록 하였다. 본 연구에서는 프로그램 개발을 위하여 IDL 6.0 (Intersys, USA)과 Visual C++ (Microsoft, USA)를 사용하였다. 전신방사선치료시 사용하는 각 에너지별 최대조직선량비(Tissue Maximum Ratio, TMR), 출력인수(output factor), 거 리 역제곱법 칙(Inverse square law), 빔 스포일 러(beam speller), 조사면(field size) 등의 인수를 데 이 터 베이스화함으로써 환자별 보상체의 자동화 제작 및 방사선량 계산을 할 수 있도록 하여 수작업으로 인해 발생할 수 있는 오차와 시간을 줄일 수 있었다. 개발된 전신방사선조사 프로그램을 활용하여 수작업으로 인한 오차를 줄이고 정확한 수치 및 데이터의 적용으로 전신방사선조사에 대한 치료계획을 최적화한다.

The patellofemoral pint is formed by the articulation of the patella and femoral condyles in the trochlear groove. The complexity of the patellofemoral pint is magnified by the fact that the tibiofemoral pint works in conjunction with the patellofemoral pint. Additionally, other pints such as the subtalar pint., hip and sacroiliac pints indirectly contribute to the function of the patellofemoral pint. This pint has little bony stability, Soft tissue surrounds the pint to increase stability. The patellofemoral pint increases the mechanical advantage of the quadriceps muscles and resists mechanical loading. In patellofemoral dysfunction, patellofemoral contact pattern is disrupted. leading to excessive compression at the pint. When you treat the patellofemoral dysfunction, you should evaluate anatomic and biomechanic components and find factors of patellofemoral dysfunction. Hamstring tightness. weakness of VMO and tightness of lateral retinaculum lead to flexed knee and abnormal patella tracking and patellofemoral pint reaction force and patellofemoral dysfunction. A through understanding of the anatomy and biomechanics may assist the clinician in the recognition and treatment of patients with patellofemoral pain. Therefore physical therapists should apply modality as well as therapeutic exercise, stretching and strengthening. In this paper, I will discuss the germane anatomical structures and biomechanics of the patellofemoral pint.

Since organized living cooperative associations sold their environment-friendly agricultural products directly to independent consumers in the past, the general distribution channels such as wholesalers had difficulty in handling these products. However, the ratio of distribution via wholesale channel has been gradually increased as consumption of environment-friendly agricultural products has expanded. This study is to address vitalization of wholesale distribution for environment-friendly agricultural products by gathering previous statistical data and analysis. In addition, statistical analysis are conducted by utilizing surveys on forwarders, consumers for environment-friendly agricultural products. As a result, the products producers ship are distributed through dealers at producers sites, producers cooperatives, or food process companies, food companies, internet shopping malls, large-scale distribution companies, consumer groups such as living cooperative associations, direct outlets at consumers sites, or exports. Among the channels, the large-scale distribution companies and franchised special shops account for 47%, the general supermarkets 15.7%, and living cooperative associations 14.6% respectively. By utilizing the research results on producers and consumers, and the distribution weight by channels for environment-friendly agricultural products, the distribution channels for living cooperative associations, wholesale markets, and large scale distribution companies are compared and evaluated. As a result, the level of producers' and consumers' satisfaction for them is the lowest since the low selling price for producers and high distribution margins.

견관절 충돌증후군의 원인은 다양하다. 대결절과 견봉과 같은 뼈의 변성으로 견봉 밑의 공간이 좁아진 경우나 회전근개가 약해지거나 관절주머니가 딱딱해지거나(capsular tightness) 상완관절의 불안정성으로 인해서 상완골두가 비정상적으로 이동하여 견봉밑의 공간이 좁아진 경우에 충돌증후군이 걸리게 된다. 충돌증후군에 걸린 어깨를 잘 치료하기 위해서는 견관절의 생체역학 해부학과 병의 원인을 잘 알아야 한다. 충돌증후군의 치료는 상완관절과 견흉관절의 운동을 회복시키고 회전근개와 견갑근육의 기능을 회복시키는데 초점을 맞춰야 한다. 또한 동적인 안정성(dynamic stabilization)을 향상시키는 운동들도 포함시켜서 치료한다. Impingement syndrome is mechanical impingement between the greater tubercle of the humerus and the under surface of the coracoacromial arch, is a common source of shoulder pain in the athletes as well as non-athletes. Several factors contribute to shoulder impingement syndrome, including rotator cuff weakness, capsular tightness, poor scapulohumeral rhythm, and muscle imbalance of the scapular upward rotation force couple. The purpose of this article is to review current concepts of anatomy and biomechanics and the underlying pathomechanics as it relates to evaluation and treatment of shoulder impingement syndrome.

목적 : 위장관종양에 대한 고선량율 강내 방사선치료의 결과를 분석하고자 하였다. 방법 : 카톨릭의대 성모병원 치료방사선과에서는 1991년 2월부터 1993년 7월까지 18명의 수술을 할 수 없는 중증의 위장관종양 환자들(식도암-8, 직장암-10)을 대상으로 Iridium-192을 사용하여 원격조정 고선량율 강내 방사선치료에 대한 후향적 분석을 하였다. 연령 분포는 47-87세로, 평균 71세였다. 모든 환자들은 이전에 수술적 조작을 받은적이 없었고, 외부 방사선치료 이후 2주 이내에 고선량율 강내 방사선치료를 하였으며, 고선량율 강내 방사선치료의 일일 조사량은 3-5 Gy(3-4회/1주), 총 조사량은 12-20Gy로 평균 17Gy였다. 외부방사선 총 조사량은 41.4-59.4Gy로 평균 49.6Gy였다. 추적기간은 3개월에서 31개월이었고, 중앙추적기간은 19개월이었다. 결과 : 식도암에서 완전관해와 부분관해는 각각 38%로 같은 결과를 보였으며, 중앙 생존기간과 2년 생존율은 10개월과 13%였다. 직장암 10명 중 60%의 환자에서 부분반응을 보였으며, 완전반응은 없었지만, 모든 환자에서 현저한 증상개선을 보였다. 저자는 고선량율 강내 방사선 일일 조사량 및 총 조사량, 외부방사선 조사량이 국소반응율과 생존율에 미치는 영향을 분석, 조사하였다. 이 중, 고선량율 강내 방사선 일일 조사량 및 총 조사량이 직장암의 국소반응율에 가장 큰 영향을 미쳤으며, 이는 통계적 유의성을 보였다 (p<0.05). 식도암에서는 고선량율 강내 방사선 총 조사량이 국소반응율과 생존율에 각각 영향을 미쳤으나, 이는 통계적 유의성은 없었다. 또한, 외부방사선 조사량은 모든 환자에게서 국소반응율과 생존율에 영향을 미치지 않는 것으로 나타났다. 모든 환자들에게서 치료 후 현저한 증상개선을 보였으며, 합병증은 대부분의 환자에서 발생하였는데, 대개의 경우 그 증상이 미비하였고, 수일 이내에 회복되었다. 결론 : 이 논문에서는 상대적으로 짧은 추적기간과 적은 수의 환자들을 대상으로 분석을 하였으나, 고선량율 강내 방사선치료 조작은 위장관 종양의 치료에서 외부 방사선치료의 추가적 요법으로 사용할 수 있을 것으로 생각된다. Purpose : Intraluminal high dose rate brachytherapy is an accepted treatment for the tumors of GI tract. However, there is only some limited clinical data for intraluminal high dose rate brachytherapy for the tumors of GI tract. Materials and Methods : Between February 1991 and July 1993, 18 patients who have the tumors of GI tract (esophageal cancer-8 cases, rectal cancer-10 cases) were treated with high dose rate Iridium-192 afterloading system (Microselectron-HDR, Nucleron CO, Netherland) at the department of therapeutic radiology, St. Mary's hospital. Catholic university medical college. Age rage was 47-87 years with a mean age 71 years. All patients were treated with intraluminal high dose rate brachytherapy within two weeks after conventional external radiation therapy and received 3-5 Gy/fraction 3-4 times per week to a total dose 12-20 Gy (mean 17 Gy), Standard fractionation and conventional dose were delivered for external radiation therapy. Total dose of external radiation therapy ranged 41.4-59.4 Gy(mean 49.6Gy). Median follow up was 19 months. Results : The analysis was based on 18 patients. The complete response and partial response in esophageal cancer wassimilar (38%). Two year rates for survival and median survival were 13% and 10 months, respectively. Among 10 patients of rectal cancers, partial response was obtained in 6 patients (60%). There was no complete response in the patients with rectal cancer, but good palliative results were achieved in all patients. Conclusion : Although the number of patients was not large and the follow-up period was relatively short, these findings suggested that intraluminal high dose rate brachytherapy could be useful in the treatment of the patients with advanced tumors of GI tract.

This study analyzes the price efficiency and causality between wholesale prices and retail prices of chinese cabbage in the five areas` consumer markets using time series analysis methods. The wholesale prices of chinese cabbage in five areas` consumer markets aim for price stability in the long-term and converge on the equilibrium price at a rapid speed although those deviate from the equilibrium price in the short-term. The retail prices of chinese cabbage in the five areas` consumer markets are about the same like the wholesale prices. But, the convergent speed of retail prices is slower than that of the wholesale prices. In addition, I find that there is the causal relationship between wholesale prices and retail prices in the vertical level of consumer market and that wholesale prices have a great effect on the retail prices. Therefore, the wholesale prices and retail prices of chinese cabbage in the five areas` consumer markets are effectively determined in a horizontal, vertical distribution structure.
