Silicone implants were noted to induce calcification when inserted for a long time, causing long-term morphologic changes. This should be taken into consideration when choosing silicone implants for augmentation rhinoplasty.

PURPOSE: There are few studies that have focused on the predictors of recurrence after gastrectomy for gastric carcinoma. This study analyzed the patients who died of recurrent gastric carcinoma and we attempted to clarify the clinicopathologic factors that are associated with the timing of recurrence. MATERIALS AND METHODS: From June 1992 to March 2009, 1,795 patients underwent curative gastric resection at the Department of Surgery, Hanyang University College of Medicine. Among them, 428 patie

Pancreas transplantation is considered a therapeutic option for patients with complicated diabetes mellitus. In this study, we compared survival rate between patients on the waiting list for pancreas transplant alone(PTA), simultaneous pancreas-kidney(SPK) transplant, and pancreas after kidney(PAK) transplant and transplant recipients. A total of 503 patients (PTA:n = 116; SPK:n = 303; PAK:n = 84) and 280 PT recipients (PTA:n = 89; SPK:n = 155; PAK:n = 36) were retrospectively analyzed at our ce

Emerging evidence suggest that long-term exposure to air pollution may induce adverse effects on the central nervous system. However, no study explored the associations in large industrial complex (IC) areas which are one of the major contributors to air pollution. Therefore, we aimed to investigate the pollution status and the association between residential proximity and incidence of neurological diseases near two major ICs characterized as multi-purposed ICs in Korea. A retrospective cohort o

코로나 19가 심화되면서 소비자들은 타인과의 불필요한 접촉을 최소화하기 위해 대표적인 비대면 서비스인 라이브 커머스 선호하기 시작하였으며, 소비자 인식을 통해 뉴노멀 시대에 적합한 플랫폼으로 성장하고 있는 상황이다. 이에 따른 소비자 관점에서의 현상연구가 필요할 것으로 생각된다. 본 연구는 소셜 빅데이터 분석을 통해 전반적인 라이브 스트리밍 커머스의 특성과 인식을 파악한다. 코로나 19 전후로 라이브 커머스에 대한 소비자들의 전반적인 인식을 비교 분석하고자 한다. 라이브 커머스의 하위카테고리인 패션과 뷰티 채널에서 나타난 소비자 인식 구조를 분석 비교하는 것도 본 연구에 포함한다. 코로나 19 전후의 라이브 커머스 대한 소비자 인식은 코로나 19 발생 시기에 따라 각각 오프라인, 온라인 기반의 속성 키워드들이 도출되었으며, 코로나 19의 영향으로 라이브 커머스의 속성 항목들이 성장하여 소비자들에게 대중화된 것으로 나타났다. 라이브 커머스 하위 카테고리인 패션 항목과 뷰티 항목에서는

Imbalances in thyroid-stimulating hormone (TSH) levels are associated with metabolic syndrome (MetS), and the underlying mechanism is partly in alignment with that of lead exposure causing MetS. Many studies have reported the association between lead exposure and MetS, but no study has considered the possibility of TSH mediating lead's effect on MetS. Therefore, we aimed to examine the association between lead exposure and MetS considering TSH as a partial mediator. The data of 1,688 adults (age

BACKGROUND Although bladder drainage is effective for monitoring urine amylase levels to detect graft rejection, enteric drainage is performed more frequently. The optimal method for monitoring pancreatic enzyme secretions remains unclear. We investigated graft survival in recipients of bladder drainage and assessed the risk of graft rejection and failure after enteric conversion. MATERIAL AND METHODS From January 1999 to October 2015, we performed 318 pancreas transplantations at our institutio

Three-dimensional computed tomography venography is a useful tool to identify increased saphenous vein diameter and provides a complementary road map for surgery in patients with varicose veins. In this study, we investigated the correlation between saphenous vein diameter on computed tomography venography and venous reflux detected on duplex ultraonography. We enrolled 152 patients (213 extremities) who underwent endovenous laser ablation therapy, following high ligation of the saphenofemoral j

Graphene has many excellent properties such as wide specific surface area, outstanding electrical mobility, and high optical transmittance. Due to these advantages, which make graphene appropriate matrix supporting vanadium for the nanocomposite. Also, depending on the synthesis process, graphene can be obtainable graphene oxide (GO) and reduced graphene oxide (RGO). Moreover, RGO has been receiving increased attention due to its nature to easily reduced to graphene, referred to as RGO, which ha

Living donor renal transplantation may be successful in patients with APS following perioperative anticoagulation therapy. However, because of the high risk of TMA or vascular thrombosis in the early postoperative period, close monitoring for hypercoagulability and continuous anticoagulation is essential for maintaining graft function.
