Purpose : To evaluate influences associated with radiation treatment planning obtained with the patient breathing freely. Materials and Methods : We compared reduction or elimination of planning target volume (PTV) margins with 2-D conventional plan with inclusion of PTV margins associated with breathing with 3-D conformal therapy. The respiratory non gated 3-D conformal treatment plans were compared with respiratory gated conventional 2-D plans in 4 patients with hepatocellular carcinomas. Isodose distribution, dose statistics, and dose volume histogram (DVH) of PTVs were used to evaluate differences between respiratory gated conventional 2-D plans and respiratory non gated 3-D conformal treatment plans. In addition. the risk of radiation exposure of surrounding normal liver and organs are evaluated by means of DVH and normal tissue complication probabilities (NTCPs). Results : The vertical movement of liver ranged 2-3 cm in all patients. We found no difference between respiratory gated 2-D plans and 3-D conformal treatment plans with the patients breathing freely. Treatment planning using DVH analysis of PTV and the normal liver was used for all patients. DVH and calculated NTCP showed no difference in respiratory gated 2-D plans and respiratory non gated 3-D conformal treatment plans. Conclusion : Respiratory gated radiation therapy was very important in hepatic tumors because radiation induced hepatitis was dependent on remaining normal liver volume. Further investigational studies for respiratory gated radiation.

견봉 쇄골 관절의 관절염 변화 및 골 용해로 인한 통증 및 기능제한은 보존적 치료를 원칙으로 하며, 보존적 치료에 실패하거나, 활동량이 많은 경우 운동선수일 경우 수술적 치료를 고려할 수 있다. 어떤 방법의 치료를 선택하던 간에 이전의 운동 범위를 얻고 통증없이 근력 및 기능회복을 할 수 있어야 하며, 이를 위해서는 잘 조절된 재활치료를 시행하는 것이 무엇보다 중요하다.

수술과 교정의 혼합술식으로 안면부의 기형과 부수적으로 발생하는 부정교합을 치료하는 경향이 점차적으로 증가하고 있다. 수술 - 교정 술식은 과거 20년동안, 특히 1970년대에 무척 빠른 속도로 발전하였다. 수술 - 교정 술식이 발달함에 따라 이전에는 수술이나 교정치료 단독으로는 치료하기가 어려웠던 case들의 치료가 가능하게 되었다. 교정의사들은 성장이 완료된 성인의 심한 skeletal dysplasia를 치아이동에 의해서만 치료하는 데에는 매우 제한이 많다는 것을 인식하게 되었으며, 반면에 구강외과 의사들은 수술전후의 교정치료에 의해 더욱 좋은 수술 결과를 얻을 수 있는 동시에 좋은 functional occlusion을 이룰수 있다는 사실을 인식하였다. 이러한 수술 - 교정 술식은 교정의사들과 구강외과의사들에게 새로운 면들을 요구하고 있다. 좋은 치료결과를 얻기 위해서는 교정의사와 구강외과의사간의 긴밀한 협조관계가 필수적이다. 이러한 협조관계를 유지하기 위하여는 서로 상대 전문분야의 용어, 진단원리, 치료기법 등에 대한 이해가 선행되어야 한다. 이 논문에서는 진단, 치료계획, 수술전 교정치료, 수술술식, 수술후 교정치료, 증례보고의 순서로 기술하려 한다.

현재의 만성질환 환자들은 잦은 검진과 치료를 요구로 한다. 하루에도 수차례 해야 하는 검사를 일일이 병원을 찾아가 할 수 없으므로 환자 개인이 측정기를 이용해 측정을 하고 있으나 그 때의 상황만 알 수 있을 뿐, 상태가 호전되고 있는지 또는 악화되고 있는지 포괄적으로 알 수 없는 것이 사실이다. 이에 본 논문에서는 개인이 가지고 있는 측정기에서 측정된 데이터를 인터넷 또는 통신모듈이 탑재된 측정기를 통해 실시간으로 전송받아 웹서비스를 통해 산재해 있는 분석엔진 시스템으로 전달하여 환자의 상태를 분석하고 의사와 환자에게 자동으로 알려줌으로써 환자에게는 자신의 현재 상태를 정확히 알고 치료에 임할 수 있게 하는 기회를 만들어 주고 의사에게는 상세한 추가정보를 비롯해 환자가 현재 제대로 치료에 임하고 있는지 확인 할 수 있는 정보를 제공하여 의사가 치료와 관련된 여러 판단을 쉽게 내릴 수 있는 만성질환자 상태 분석 및 제공 시스템을 제안하고자 한다.

Purpose: To evaluate the rate of tumor response, local control, and treatment-related complications after hypofractionated radiotherapy for recurrent hepatocelluar carcinoma (HCC) less than 5 cm in size. Materials and Methods: Among the HCC patients who were treated by radiotherapy (RT) between 2006 and 2007 after the failure of previous treatment, a total of 12 patients were treated with hypofractionated RT. The criteria for hypofractionated RT was as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to a critical organ, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that irradiated 50% of the prescribed dose. Hypofractionated RT was performed with 50 Gy delivered in 10 fractions, at a rate of 5 fractions per week. The evaluation of tumor response was determined by CT scans performed at 3 months after the cessation of RT, followed by the evaluation of toxicity by Common Terminology Criteria for Adverse Events version 3.0. The median follow-up period after radiotherapy was 18 months. Results: A complete response (CR) was achieved in 5 of 12 lesions (41.7%) at CT performed at 3 months after the cessation, whereas the overall complete response was observed in 7 of 12 cases (58.3%). In-field local control rate was sustained in 83.3% of patients. All patients developed intra-hepatic metastases except for 2 patients. The overall survival rate was 90.0% at 1 year and 67.5% at 2 years, respectively. Three patients developed Grade 1 nausea during RT and 1 patient showed a progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusion: Hypofractionated RT for small-sized HCC as a salvage therapy showed a 58.3% CR rate and 83.3% of local control. Fifty Gy administered in 10 fractions of partial liver irradiation is considered as a tolerable dose that does not cause severe complications.

The purpose of this study was to survey the intervention model, intervention settings, intervention time, factors influencing selection of intervention model, relationship between intervention model and areas which supporting center for special education based occupational therapist was using. Study data were provided by 46 therapy supporting service professionals through e-mail and analyzed. The findings indicated that first, the therapy supporting service professionals often employed a direct therapy(individual) focusing on performance component of child. Second, they believed that direct therapy is most effective in improving children's performance and raising awareness of the importance of occupational therapy. Third, when choose intervention model, they took into consideration the child's performance components deficits and mind of team chief. Fourth, no correlation between the application time and the perception of effectiveness of intervention model. Also didn't find correlation between applying time of intervention model and intervention area. When putting the various research result together, the model school-based occupational therapists using was similar to medical model. Therefore it is need a study to develop effective intervention model and apply it in school environment.

Objective : The purpose of this study was to understand the degree of verbal violence experienced by occupational therapist's and its effects on job stress and turnover intention. Methods : The data analyzed in this study were collected using a mobile device. We collected 316 responses to a questionnaire. Occupational therapists responded to the study. We analyzed their experiences of verbal violence from patients, and caregivers, job stress, and turnover intentions. Results : The results showed that occupational therapists experienced greater' verbal violence from patients than caregivers. The average job stress level was 2.79 (±1.15). The turnover intention was 3.41 (±1.19), which was higher than normal. The degree of verbal violence, job stress, and turnover intention were positively correlated for all variables. Conclusion : A correlation was found between the degree of verbal violence experienced by occupational therapists, job stress, and turnover intention. Further investigations with a wider sample population are required to verify the results.

Intraocular melanoma is the most common primary occular malignancy in adult above the age of 20. Before treatment of intraocular melanoma, it is essential to do complete work-ups including LFT (LDH, SGPT), chest X-ray, whole body bone scan. Also, liver-spleen and brain scan will be done if clinically indicated. Though, malignant melanoma is radioresistant, however, show rapid tumor shrinkage after irradiation with total tumor dose of 7,000 to 8,000 rads in 7-8 weeks.
