This paper aims to trace where the border between Goguryeo and Shilla was in the 5th and 6th centuries, and to examine the structure of the border area between these two ancient kingdoms. The border between Goguryeo and Shilla changed distinctively, over three time periods. ⑴ The 1st Stage (~450AD)The border between the two kingdoms was formed when King Gwang'gaeto-wang of Goguryeo occupied the Bukhan-gang River basin of Baekje and rescued Shilla from the attack of the Japanese pirates in the ea

Minimally invasive surgery reduces surgical trauma and the size and number of incisions. The da Vinci SP robotic surgical system was designed to overcome the technical demands of single-incision laparoscopic surgery. This study aimed to demonstrate the safety and feasibility of single-port (SP) robotic distal gastrectomy (SPRDG) for patients with gastric cancer using the da Vinci SP system (Intuitive Surgical Inc., Sunnyvale, CA, USA). This study was designed as a single-arm prospective phase I/

Introduction Abdominal computed tomography (CT) can accurately demonstrate organs and vascular structures around the stomach, and its potential role for image guidance is becoming increasingly established. However, solely using two-dimensional CT images to identify critical anatomical structures is undeniably challenging and not surgeon-friendly. To validate the feasibility of a patient-specific 3-D surgical navigation system for preoperative planning and intraoperative guidance during robotic g

This paper aims to examine the earthen fortresses constructed for the first time in Yeongnam province. Early earthen fortresses are very important materials in that they have relation to the state formation and the control of the provinces in ancient Korea. However, they have been less concerned than tomb materials because they have not been excavated sufficiently. There are three different viewpoints to understand early earthen fortresses: These are thought to have been built ① before the forma

BACKGROUND: Fluorescent lymphography-guided lymphadenectomy (FL) for gastric cancer is gaining popularity. However, its impact on prognosis is not known. This study aimed to assess the prognostic impact of FL in gastric cancer patients. MATERIALS AND METHODS: This study retrospectively analyzed 5678 gastric cancer patients who underwent gastrectomy from 2013 to 2017. The survival was compared between the FLFL group and the conventional lymphadenectomy (non-FL group) using 1:1 propensity score ma

Objective: To suggest the possible indication of proximal gastrectomy for advanced gastric cancer located at the upper third of the stomach. Background: Proximal gastrectomy has been an alternative surgical procedure for early proximal gastric cancer due to its benefits for quality of life while maintaining oncological outcomes. However, the oncological safety of proximal gastrectomy for advanced tumors remains unclear. Methods: We retrospectively reviewed data from 878 patients who underwent ra

Sophisticated movements, articulating instruments, and the rapid introduction of fast-developing novel technology make robotic gastrectomy use more frequent. However, the need for well-designed prospective randomized trials is warranted.

Pohang Jungseongri Silla Stone Monument was discovered in 2009 and has been studied for over 2 years. However, its inscription couldn’t be understood because there are many lists of names and a few verbs. There is a gyo (敎, king’s order) in the inscription, but it has not been agreed on what the content of the gyo is. I think that it is because the inscription is not the record of the gyo itself, but that of the procedure to resolve a dispute by the gyo. The gyo was issued in the first sentence,

신라 郡縣에 村이 속해 있었다는 것은「 신라 촌락 문서」등을 통하여 알려져 있지만, 그 중심지가 어떤 형태로 되어 있었는지, 지방관아가 구체적으로 어디에 위치하였는지에 대해서는 연구가 거의 이루어지지 못하였다. 본 연구에서는「 남산신성비」에 道使(邏頭)가 파견된 것으로 되어 있는 城·村을 통일기까지 지방관이 상주한 군현의 중심공간으로 이해하였고, 군현 중심지로 추정되는 지점에 위치한 城址, 고분군, 취락지, 건물지 등을 검토하여, 지방관아의 위치를 비정해 보았다. 『삼국사기』지리지에는 尙·良·康州가 原 신라 지역이라고 되어 있지만, 지난 연구에서 이 3州의 영역이 적어도 3단계에 걸쳐 형성되었다고 하였다. 이것을 토대로 原 신라 內地 지역의 수창군·대구현, 팔리현, 장산군, 해안현, 자인현, 하곡현, 原 신라 邊境지역의 삼년군, 화령군, 그리고 6세기 중엽 이후에 진출한 옛 가야 지역의 함안군, 거제군, 남해군의 사례를 검토해 보았다. 대부분 군현 중심지에는 축조 연대는 다르지만 성

郡縣城이란 군현제를 실시할 때 군현으로 편제되는, 군현과 이름이 같은 성을 말 하며, 주요 신라 城址가 군현 중심지로 추정되는 지점에 위치한다는 점에서 그 遺址를 실물로서 확인할 수 있다(ex. 三年山城-三年山郡). 이 논문의 일차적인 관심은 신라 9州중 原영역이라고 하는 尙·良·康州지역을 대상으로 모든 군현에 대응하는성지가 있는지, 또 대응하는 성지의 양상이 어떠한지 확인하는 것이다. 조사 결과 대부분의 군현에서 대응 성지를 확인할 수 있었지만, 일부 찾기 어려 운 경우도 있었다. 대응 성지는 토성, 전형적인 석축 산성, 성벽의 구조가 뚜렷하지 않아 흔히 ‘토석혼축’으로 분류되는 산성 등으로 나타났는데, 이는 이 지역의 군현 성이 여러 단계에 걸쳐 형성되었으며, 지역에 따른 필요의 차이도 작용했기 때문이 라고 생각된다. 즉 초기 토성의 축조가 1단계로 4세기 중엽에서 5세기 중엽까지이며, 신라 국가는 교통로를 따라서 토성을 구축하였는데, 이들을 거점으로 지배력을 線的으로 확장시켜

The present study investigated the use of cell-cycle regulators for predicting the progression of silent pituitary adenoma (SPA) following surgical resection, via immunohistochemical analysis of tumor samples obtained by surgical resection. The medical records of patients diagnosed with SPA between January 2000 and December 2013 in the Samsung Changwon Hospital, Sungkyunkwan University School of Medicine (Changwon, South Korea) were reviewed. Immunohistochemical staining was performed on section

Splenic hilar LND with or without splenectomy may not have an oncological benefit for patients with pathological AGC with no LN metastasis.
