본 논문에서는 영상생성이 가능한 딥러닝 네트워크를 이용하여 조영증강 CT 영상을 획득하는 연구를 수행하였다. CT는 고해상도 영상을 바탕으로 환자의 질병 및 암 세포 진단에 사용되는 의료영상 기법 중 하나이다. 특히, 조영제를 투여한 다음 CT 영상을 획득되는 영상을 조영증강 CT 영상이라 한다. 조영증강된 CT 영상은 물질의 구성 성분의 영상대비를 강조하여 임상의로 하여금 진단 및 치료반응 평가의 정확성을 향상시켜준다. 하지많은 수의 환자들이 조영제 부작용을 갖기 때문에 이에 해당되는 환자의 경우 조영증강 CT 영상 획득이 불가능해진다. 따라서 본 연구에서는 조영증강 영상을 얻지 못하는 환자 및 일반 환자의 불필요한 방사선의 노출을 최소화 하기 위하여 영상생성 딥러닝 기법을 이용하여 CT 영상에서 조영증강 CT 영상을 생성하는 연구를 진행하였다. 영상생성 딥러닝 네트워크는 generative adversarial network (GAN) 모델을 사용하였다. 연구결과 아무런 전처리도 거치지 않은 CT 영상을 이용하여 영상을 생성하는 것 보다 히스토그램 균일화 과정을 거친 영상이 더 좋은 결과를 나타냈으며 생성영상이 기존의 실제 영상과 영상의 구조적 유사도가 높음을 확인할 수 있다. 본 연구결과 딥러닝 영상생성 모델을 이용하여 조영증강 CT 영상을 생성할 수 있었으며, 이를 통하여 환자의 불필요한 방사선 피폭을 최소하며, 생성된 조영증강 CT 영상을 바탕으로 정확한 진단 및 치료반응 평가에 기여할 수 있을거라 기대된다.

Peripheral arterial disease is an occlusive condition commonly involving the lower extremity vessels. When the aortoiliac region is affected by this disease, conventional management involves surgical bypass and endovascular treatment has been mainly recommended for patients with focal and simple lesions. It has been common strategy to perform endovascular treatment for selected patients with high surgical risk due to its minimally invasive nature. However, recent advances in the devices and techniques for endovascular treatment have resulted in its utilization for treating patients with various disease status and its clinical outcomes are comparable to those of conventional surgery. This review discusses the current diagnostic strategies for peripheral artery disease in the aortoiliac region, followed by the introduction of techniques and devices, and the role of endovascular treatment.

Unlike other common forms of speech disorder, such as phonological disorder or dysphonia, stuttering has not been studied within the context of music therapy. Most cases of stuttering display no difficulty in singing, and fluency within the musical structure does not translate to fluency in speech. Hence, musical approach has been generally considered to be ineffective to the treatment of stuttering. However, the fundamentals of music therapy assume its extensive application in treating variety of speech disorders, including the case of stuttering. Presented in this paper are the case studies designed to validate the efficacy of music therapy as a remedy for stuttering. This study enrolled 6 children with stuttering and conducted 20 individual sessions over a period of 10 weeks. The sessions focused on the Melodic Intonation Therapy, Reinforcement of speech rhythm, song writing and singing. Musical elements were structured to enhance the verbal expression and rhythmic senses, as well as to facilitate the initiation of verbal communication. The result is as follows. First, it was noticed that the disfluency had been decreased in before and after of the music therapy in every child although the result was somewhat different depending the child. The overall result of the investigation shows the significant difference statistically. And categorically speaking, the significant difference was checked in the frequency of the stuttering. In the steps of the session, the increase and decrease was happened repeatedly, and then after it was decreased little by little. Secondly, the Communication Attitude was decreased in before and after of the music therapy, and also there was significant difference statistically. although the avoidance behavior was decreased in before and after of the music therapy, the increase and the decrease was repeated irregularly in the steps of session. All the results described above shows that music therapy gives positive effect to decrease in disfluency of stuttering child and also to develop the Communication Attitude. And new possibility and effectiveness can be proposed in the musical approach to the stuttering.

Purpose : The dose distribution of organ at risk (OAR) and normal tissue is affected by treatment technique in postoperative radiation therapy for prostate cancer. The aim of this study was to compare dose distribution characteristic and to evaluate treatment efficiency by devising VMAT plans according to applying differed number of arc and IMRT plan for postoperative patient of prostate cancer radiation therapy using a rectal balloon. Materials and Methods : Ten patients who received postoperative prostate radiation therapy in our hospital were compared. CT images of patients who inserted rectal balloon were acquired with 3 mm thickness and 10 MV energy of HD120MLC equipped Truebeam STx (Varian, Palo Alto, USA) was applied by using Eclipse (Version 11.0, Varian, Palo Alto, USA). 1 Arc, 2 Arc VMAT plans and 7-field IMRT plan were devised for each patient and same values were applied for dose volume constraint and plan normalization. To evaluate these plans, PTV coverage, conformity index (CI) and homogeneity index (HI) were compared and $R_{50%}$ was calculated to assess low dose spillage as per treatment plan. $D_{25%}$ of rectum and bladder Dmean were compared on OAR. And to evaluate the treatment efficiency, total monitor units(MU) and delivery time were considered. Each assessed result was analyzed by average value of 10 patients. Additionally, portal dosimetry was carried out for accuracy verification of beam delivery. Results : There was no significant difference on PTV coverage and HI among 3 plans. Especially CI and $R_{50%}$ on 7F-IMRT were the highest as 1.230, 3.991 respectively(p=0.00). Rectum $D_{25%}$ was similar between 1A-VMAT and 2A-VMAT. But approximately 7% higher value was observed on 7F-IMRT compare to the others(p=0.02) and bladder Dmean were similar among the all plan(P>0.05). Total MU were 494.7, 479.7, 757.9 respectively(P=0.00) for 1A-VMAT, 2A-VMAT, 7F-IMRT and at the most on 7F-IMRT. The delivery time were 65.2sec, 133.1sec, 145.5sec respectively(p=0.00). The obvious shortest time was observed on 1A-VMAT. All plans indicated over 99.5%(p=0.00) of gamma pass rate (2 mm, 2%) in portal dosimetry quality assurance. Conclusion : As a result of study, postoperative prostate cancer radiation therapy for patient using a rectal balloon, there was no significant difference of PTV coverage but 1A-VMAT and 2A-VMAT were more efficient for dose reduction of normal tissue and OARs. Between VMAT plans. $R_{50%}$ and MU were little lower in 2A-VMAT but 1A-VMAT has the shortest delivery time. So it is regarded to be an effective plan and it can reduce intra-fractional motion of patient also.

Many healing programs regard successful healing as the cure of the presenting physical and emotional problems. To heal present broken heart on a smart environment, we need to know states of mind. We also have to need psychoanalytic healing that cure mind caused. It is necessary to consider a more comprehensive view of healing that incorporates not only physical healing but mental healing. For this, we analyze through retrospective review from existing researches and healing programs. We obtain psychological and emotional factors about negative side effects on a smart environment. Throughout this study we draw upon factors of psychology and emotion to represent pictures by projective methods such as visual representation. That pictures is being used in developing the digital workbook for mind healing. We look at the possibility of psychological therapy from negative side effects causing converts into digital forms which have fixed scales on a smart environment.
