Background: In daily practice, three-dimensional patient-specific jawbone models (3D models) are a useful tool in surgical planning and simulation, resident training, patient education, and communication between the physicians in charge. The progressive improvements of the hardware and software have made it easy to obtain 3D models. Recently, in the field of oral and maxillofacial surgery, there are many reports on the benefits of 3D models. We introduced a desktop 3D printer in our department, and after a prolonged struggle, we successfully constructed an environment for the "in-house" fabrication of the previously outsourced 3D models that were initially outsourced. Through various efforts, it is now possible to supply inexpensive 3D models stably, and thus ensure safety and precision in surgeries. We report the cases in which inexpensive 3D models were used for orthodontic surgical simulation and discuss the surgical outcomes. Review: We explained the specific CT scanning considerations for 3D printing, 3D printing failures, and how to deal with them. We also used 3D models fabricated in our system to determine the contribution to the surgery. Based on the surgical outcomes of the two operators, we compared the operating time and the amount of bleeding for 25 patients who underwent surgery using a 3D model in preoperative simulations and 20 patients without using a 3D model. There was a statistically significant difference in the operating time between the two groups. Conclusions: In this article, we present, with surgical examples, our in-house practice of 3D simulation at low costs, the reality of 3D model fabrication, problems to be resolved, and some future prospects.

Purpose: Methylmethacrylate is the most commonly used alloplastic material in cranioplasty. However during the polymerization of methylmethacrylate, a significant exothermic reaction takes place. This reaction may result in thermal injury to the brain tissue and other soft tissues. Also it is difficult to make three-dimensional methylmethacrylate implant that is perfectly matched to the defect during the operation time. We report on the molding technique of methylmethacrylate implant using plaster mold and the rapid prototyping model in cranioplasty. Methods: A 44-year-old male was referred to the department for severe frontal hollowness. He was involved in an automobile accident resulting in large frontal bone defect with irregular margin. The preformed patient-specific methylmethacrylate implant was made using plaster mold and the rapid prototyping model before the operative day. The methylmethacrylate implant was placed in the frontal defect and rigidly fixed with miniplates and screws on the operative day. Results: The operation was performed in an hour. In the 6 months follow-up period, there were no complications. Patient was satisfied with the results of cranioplasty. Conclusion: Safe cranioplasty was performed with the preformed patient-specific methylmethacrylate implant using plaster mold and the rapid prototyping model. The result of this method was satisfactory, aesthetically and functionally.

음악치료는 장애아동 및 정신치료에 많은 효과를 보이고 있다. 오늘날의 음악치료 시스템은 구체적인 치료 시스템이 구축되어 있지 않은 상황으로, 음악 치료사들이 정확한 치료를 하기 위해 다양한 음악치료 사례들과 치료 이력 데이터들을 분석하고, 해당 환자 또는 내담자에게 가장 적합한 치료를 시행해야 하지만, 현실은 여러 가지 요인들로 인해 많은 어려움이 따르고 있다. 이를 해결하고자 본 논문에서는 기존 치료 데이터와 텍스트 마이닝 기술을 융합한 음악치료 지식관리 모델을 제안한다. 제안 모델을 활용하면 유사한 사례검색 및 환자에 관련된 구체적이고 확실한 데이터들을 기반으로 환자 또는 내담자로 하여금 정확하고 효과적인 치료가 가능하다. 이를 통해서 음악치료의 본래 목적과 그 효과를 최대로 이끌어 내는 효과를 기대할 수 있고 나아가 많은 환자들의 치료에 도움이 될 것으로 기대된다.

최근 의과대학과 의료서비스 산업에서 환자-의사 커뮤니케이션에 관한 논의가 활발히 이루어지고 있다. 환자-의사 커뮤니케이션이란 '진료면담'에서 환자와 의사간의 쌍방향 의사소통으로써, 환자와 의사 양자에게 모두 긍정적인 효과를 가져다주는 것으로 알려져 있다. 이 연구에서는 의사의 커뮤니케이션 스킬을 향상시켜 환자와 의사간의 의사소통을 원활히 할 수 있는 방안으로 코칭기법을 접목한 의사코칭 모델을 개발하였다. 모델 개발 방법은 문헌검토를 통해 초안을 개발하였고, 전문가 자문과 의사평가를 통해 수정 보완하였다. 연구 결과, 의사코칭 모델을 총 5단계로 구성하였다. 첫째, '관계 형성'으로 의사가 코칭에 대한 기대나 관심을 가지도록 한다. 둘째, '변화 주제 인식'으로 환자와의 커뮤니케이션에서 의사의 문제점과 장점을 파악하여 코칭의 방향을 설정한다. 셋째, '관점의 획득'으로 의사가 환자의 관점에서 생각할 수 있도록 유도한다. 넷째, '문제 해결 및 의사소통 역량 강화'로서 의사의 커뮤니케이션 스킬 개선사항을 세부항목으로 제시한다. 다섯째, '목표 설정 및 지원'으로 개선 사항 목표를 설정하고 장점을 유지 강화할 수 있는 실천 방안을 합의한다. 개발된 의사코칭 모델은 환자-의사 커뮤니케이션 개선을 위해 의사들을 대상으로 코칭기법을 처음으로 적용했다는데 가장 큰 의의가 있다. 향후 의료서비스 현장에서 활용될 경우, 의사들의 커뮤니케이션 스킬 향상과 환자 공감적 능력 향상에 효과가 있을 것으로 판단된다. 이를 통해 환자들의 진료만족도를 높이는데 기여할 것이다.

With the development of computer-aided design/computer-aided manufacturing (CAD/CAM) technology, it has been possible to reconstruct the cranio-maxillofacial defect with more accurate preoperative planning, precise patient-specific implants (PSIs), and shorter operation times. The manufacturing processes include subtractive manufacturing and additive manufacturing and should be selected in consideration of the material type, available technology, post-processing, accuracy, lead time, properties, and surface quality. Materials such as titanium, polyethylene, polyetheretherketone (PEEK), hydroxyapatite (HA), poly-DL-lactic acid (PDLLA), polylactide-co-glycolide acid (PLGA), and calcium phosphate are used. Design methods for the reconstruction of cranio-maxillofacial defects include the use of a pre-operative model printed with pre-operative data, printing a cutting guide or template after virtual surgery, a model after virtual surgery printed with reconstructed data using a mirror image, and manufacturing PSIs by directly obtaining PSI data after reconstruction using a mirror image. By selecting the appropriate design method, manufacturing process, and implant material according to the case, it is possible to obtain a more accurate surgical procedure, reduced operation time, the prevention of various complications that can occur using the traditional method, and predictive results compared to the traditional method.

Objective : Recently, three-dimensional (3D) printed models of the intracranial vascular have served as useful tools in simulation and training for cerebral aneurysm clipping surgery. Precise and realistic 3D printed aneurysm models may improve patients' understanding of the 3D cerebral aneurysm structure. Therefore, we created patient-specific 3D printed aneurysm models as an educational and clinical tool for patients undergoing aneurysm clipping surgery. Herein, we describe how these 3D models can be created and the effects of applying them for patient education purpose. Methods : Twenty patients with unruptured intracranial aneurysm were randomly divided into two groups. We explained and received informed consent from patients in whom 3D printed models-(group I) or computed tomography angiography-(group II) was used to explain aneurysm clipping surgery. The 3D printed intracranial aneurysm models were created based on time-of-flight magnetic resonance angiography using a 3D printer with acrylonitrile-butadiene-styrene resin as the model material. After describing the model to the patients, they completed a questionnaire about their understanding and satisfaction with aneurysm clipping surgery. Results : The 3D printed models were successfully made, and they precisely replicated the actual intracranial aneurysm structure of the corresponding patients. The use of the 3D model was associated with a higher understanding and satisfaction of preoperative patient education and consultation. On a 5-point Likert scale, the average level of understanding was scored as 4.7 (range, 3.0-5.0) in group I. In group II, the average response was 2.5 (range, 2.0-3.0). Conclusion : The 3D printed models were accurate and useful for understanding the intracranial aneurysm structure. In this study, 3D printed intracranial aneurysm models were proven to be helpful in preoperative patient consultation.

The purpose of this study Is to find out the design guideline for women's hospital focusing on the patient needs. The results of research are as follows: 1) As a basic frame of evaluation model, the quality of service of medical facilities and patients' reaction to the physical environment are fixed as a variable called' satisfaction degree'. This study analyzes the influence on space efficiency evaluation according to the difference of types through basic model (Model I-1,2) as verification model to identify the difference between satisfaction degree of outpatients and that of inpatients. 2) The difference of satisfaction degree about the hospital facilities by space evaluation matrix is according to the types of inpatients and to space importance. 3) The control of importance degree about the interior facilities of the hospital according to the specific character of the hospital is necessary. Maintenance of the status quo, or reduction, or expansion is needed according to the satisfaction degree corresponding to the importance degree. Finally, the model is used to for the planning & design for the future women's hospital.
