Diabetic foot wounds have a significant effect on the health-related quality of life of patients. As diabetic foot wounds are usually chronic and recurrent, it is possible that they can lead to skin malignancies. Several factors can make it difficult to make an early and accurate diagnosis of skin malignancies of the foot in patients with diabetes mellitus. Even though the prevalence of diabetes mellitus and diabetic foot wounds is increasing, currently there are no guidelines for the biopsy of diabetic foot wounds. We have evolved a criterion for the above based on six cases of diabetic foot wounds with concomitant skin malignancies. We recommend that clinicians should broadly consider implementing this criterion when managing patients with diabetic foot wounds.

The purpose of this study was to examine the frequency of dehiscence bone defect on peri-implant and to compare the difference between resorbable membrane and nonresorbable membrane in bone regeneration on peri-implant. Amomg the patients, 22 patientswho have recieved an implant surgery at the department of Periodontics in Dankook University Dental Hospital showed implant exposure due to the dehiscence defect and 27 implants of these 22 patients were the target of the treatment. $Gore-Tex^{(R)}$ and $Bio-mesh^{(R)}$ were applied to the patients and treated them with antibiotics for five days both preoperatively and postoperatively. Reentry period was 26 weeks on average in maxilla and 14 weeks on average in mandible. The results were as follows : 1. Dehiscence bone defect frequently appeared in premolar in mandible and anterior teeth in maxilla respectively. 2. Among 27 cases, 2 membrane exposures were observed and in these two cases, regenerated area was decreased. 3. In non-resorbable membrane, bone surface area $9.25{\pm}4.84$ preoperatively and significantly increased to $11.48{\pm}7.52$ postoperatively.(P<0.05) 4. In resorbable membrane, bone surface area was $14.80{\pm}8.25$ preoperatively and meaningfully widened to $17.61{\pm}10.67$ postoperatively.(P<0.05) 5 . The increase of bone surface area in non-resorbable membrane was $2.23{\pm}3.38$ and the increase of bone surface area in resorbable membrane was $2.80{\pm}3.00$ ;therefore, there was no significant difference between these two membranes(P<0.05). This study implies that the surgical method using DFDB and membrane on peri-implant bone defect is effective in bone regeneration regardless the kind of the membrane, and a similar result was shown when a resorbable membrane was used.

Statement of problem : Most posts are metallic, but in response to the need for a post that possesses optical properties compatible with an all-ceramic crown. an esthetic post has been developed. Although there have been many studies about the esthetic post materials, 3-dimensional finite element studies about the stress distribution of them are in rare. Purpose : The purpose of this study is to investigate comparatively the distribution of stresses of the restored, endodontically treated maxillary incisors with the esthetic post materials and the displacement on the cement layer on simulated occlusal loading by using a 3-dimensional finite element analysis model. Material and method : Four 3-dimensional finite element models were constructed in a view of a maxillary central incisor, a post, a core, and the supporting tissues to investigate the stresses in various esthetic posts and cores and the displacement on the cement layer (Model 1 ; Cast gold post and core, Model 2 ; Glass fiber post with composite core, Model 3 ; Zirconia post with composite core. Model 4 ; Zirconia post with ceramic core). Force of 300N was applied to the incisal edge and the cingulum (centric stop point) with the angle of 135-degree to the long axis of the tooth. Results : 1. The stresses and displacement on the incisal edge were higher than on the cingulum 2. The stresses in dentin were the highest in Model 2 (Glass fiber post with composite core), and the second was Model 3, the third Model 1, and the lowest Model 4. 3. The stresses in post and core were the highest in Model 4 (Zirconia post with ceramic core), and the second was Model 1, the third Model 3, and the lowest Model 2. 4. The displacement on the cement layer was the highest in Model 2 (Glass fiber post with composite core), and the second was Model 3, the third Model 1, and the lowest Model 4. Conclusion : When a functional maximum bite force was applied, the distribution of stresses or the esthetic post and core materials and the displacement on the cement layer were a little different. It seems that restoring extensively damaged incisors with esthetic post and core materials would be decided according to the remaining tooth structure.

Relay systems have recently gained attentions because of its capability of cell coverage extension and the power gain as the one of key technologies for 5G. Relays can be exploited for small-cell base stations and the autonomous network, where communication devices communicate with each other cooperatively. Therefore, the relay technology is expected to enable the low power and large capacity communication. In order to maximize the benefits of using a limited number of relays, the efficient relay selection method is required. Especially, when two nodes exchange their data with each other via relay, the relay selection can maximize the average data rate by the spatial location of the relay. For this purpose, the average data rate is analyzed first according to the relay selection. In this paper, we analyzed the average data rate when two nodes exchange their data via dual-hop decode and forward relaying considering the interference by the concurrent transmission under Nakagami-m fading channel. The correctness of the analysis is verified by the Monte Carlo simulation. The results show that the concurrent transmission is superior to the non-concurrent transmission in the high required data rate region rather than in the low required data rate region. 최근 5G에 기술에서는 신호 감쇄와 신호 도달 거리 확장을 위해 사용될 수 있는 릴레이(Relay)를 통한 통신 기술이 주목 받고 있다. 릴레이는 소형 기지국으로 사용이 가능하며, 셀룰러 망으로 지원하기 어려운 환경하에서 통신 기기들이 협력하여 통신하는 자율 네트워크 기법에 사용이 가능하기 때문에, 저전력화와 무선 용량 증대에 활용이 가능할 것으로 기대되고 있다. 한정된 릴레이 자원을 활용하여 최적의 성능을 달성하기 위해서는 효과적인 릴레이 선택 기법이 필요하다. 특히, 두 개의 노드가 릴레이를 통해 메시지를 교환하는 경우, 릴레이 선택 방법에 따라서, 릴레이의 공간적 위치를 활용하여 간섭을 줄이고, 시스템 전송률을 최대화 할 수 있다. 이를 위해서는 릴레이 선택에 따른 평균 데이터 전송률에 대한 분석이 선행되어야 한다. 본 논문은 두 노드가 릴레이를 이용하여 동시 전송을 통해 메시지를 교환할 경우, 평균 데이터 전송률을 분석한다. 이를 위해 Nakagami-m 페이딩 채널 환경하에서 복호 후 전송(Decode and Forward)방식으로 동작하는 이중홉(dual-hop) 릴레이의 동시 전송으로 인한 간섭을 고려하여 전체 데이터 전송률을 유도한다. 분석식은 m=1인 Rayleigh 페이딩 채널을 포함하여 다양한 Nakagami-m 페이딩 채널에 대한 전체 데이터 전송률을 보여준다. 유도된 분석은 몬테카를로 모의실험을 통해 정확성을 입증하였으며, 요구되는 데이터 전송률이 높을수록, 자원 효율적인 동시 전송 방식이 전체 시스템의 성능을 향상시킬 수 있음을 확인하였다.
