Long-Term Survival after Wide Resection of Malignant Fibrous Histiocytoma of the Chest Wall
신진원,장용진,조덕곤,최시영 대한흉부외과학회 2019 Journal of Chest Surgery (J Chest Surg) Vol.52 No.1
Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.
코로나19로 확대된 반중·반미·반일 정서와 담화특징 연구: 신문사설 헤드라인을 중심으로

This study aims to explore discursive characteristics of the representation of negative sentiments toward China, the United States, and Japan in Korean newspaper headlines published during the first year of the COVID-19 pandemic outbreak. To this end, it (i) investigates the criteria for and types of evaluative words adopted to express negative sentiments toward the three nations, (ii) explores differences in rhetorical characteristics that reveal the editorial positions favored by the news agencies, and (iii) discusses how the political ideologies of the news agencies are affecting the types of negative attitudes they express toward these three nations. Based on the appraisal theory proposed by Martin and White (2005), this paper analyzes editorial headlines from two major Korean daily newspapers, Chosun Ilbo and Hankyoreh, which have been chosen as respective representatives of conservative and progressive newspapers. The result of the analysis suggests that the ideological orientations of the newspapers tend to influence which nation becomes a target of negative evaluations and which strategy is adopted to reach these conclusions. Also, it shows that the intensity and frequency of these evaluations are reflective of the overall sentiments of our society.

The purpose of this study is to examine the correlation between the collective perspective of Korean society towards overseas adopted Koreans and the language choices used by journalists. The study also aims to explore how this perspective relates to the key issues identified in previous humanistic and sociological research on adopted Koreans. To achieve this goal, the paper analyzes the headlines of 11 Korean newspapers published over a period of two decades, using van Leeuwen’s discourse analysis model to bridge content and linguistic analysis at the text level. The findings of the study reveal that the discourse surrounding adopted Koreans involves multiple social actors including the adoptees themselves, their country of birth, their biological families, and other stakeholders. It also shows that Korean society collectively recognizes that the Korean government or society should take responsibility for the overseas adoptees. Furthermore, the research findings align with previous sociological studies on the overseas adoptees, as well as research exploring fictional portrayals of adoption in movies and novels. Overall, this study sheds light on how Korean society perceives and talks about the adopted Koreans, and how this perspective is linked to some major issues raised by the other research on the adoptees.
유한요소 모델링에 의한 보-기둥 볼트 접합부의 내진성능 예측
신진원,김병윤 한국방재학회 2018 한국방재학회논문집 Vol.18 No.7
이 논문은 모멘트 골조의 볼트 접합부 내진성능을 유한요소법으로 평가한 수치해석적 연구에 대하여 기술하였다. 과거의 실험적 연구를 이용하여 수치해석모델의 정확도를 검증하였으며, 재료시험결과, 컨택요소, 볼트 프리텐션, 비선형 이동 경화 알고리즘 등을 이용하여 접합부의 3차원 솔리드 해석모델을 수립하였다. 두가지 유형의 수치해석모델을 제안하였는데, 하나는 솔리드와 컨택 요소를 이용한 모델, 다른 하나는 전산해석비용을 효과적으로 줄이기 위한 쉘 요소와 커넥터를 이용한 모델이다. 제안한 솔리드 컨택 모델과 쉘 커넥터 모델, 그리고 비선형 이동 경화 알고리즘의 합리성을 반복하중 실험결과를 통해 검증하였다. 취성 파단과 같은 접합부의 국부 거동을 주로 사용되는 파괴지수를 도입하여 분석하였으며, 분석결과들을 실험결과와 비교하여 논의하였다. This paper presents a numerical study using the finite element method to evaluate the seismic performance of bolted connections within a steel moment-resisting frame. The accuracy of the numerical models was validated using past experimental studies. Three dimensional connection models were constructed using the results of material tests and consideration of contact elements, bolt pretension, nonlinear kinematic hardening algorithms, etc. Two types of numerical models were proposed, one using solid and contact elements, and the other using shell elements and connectors to effectively reduce the computational cost. The rationality of the solid contact model, the shell connector model, and the nonlinear kinematic hardening algorithm was demonstrated via cyclic loading tests. The local responses, including brittle fracture, were analyzed utilizing frequently used fracture indices such as TI and RI, where the analysis results are discussed by comparison to the relevant test results.

Background: The purposes of this study were to evaluate the appropriateness of the stage migration of stage IIA non-small cell lung cancer (NSCLC) in the seventh edition of the tumor, node, and metastasis classification for lung cancer to stage IIB lung cancer in the eighth edition, and to identify prognostic factors in patients with eighth-edition stage IIB disease. Methods: Patients with eighth-edition stage IIB disease were subclassified into those with seventh-edition stage IIA disease and those with seventh-edition stage IIB disease, and their recurrence-free survival and disease-specific survival rates were compared. Risk factors for recurrence after curative resection were identified in all included patients. Results: Of 122 patients with eighth-edition stage IIB NSCLC, 101 (82.8%) had seventh-edition stage IIA disease and 21 (17.2%) had seventh- edition stage IIB disease. Nonsignificant differences were observed in the 5-year recurrence-free survival rate and the 5-year disease-specific survival rate between the patients with seventh-edition stage IIA disease and those with seventh-edition stage IIB disease. Visceral pleural invasion was a significant risk factor for recurrence in patients with eighth-edition stage IIB NSCLC. Conclusion: The stage migration from seventh-edition stage IIA NSCLC to eighth-edition stage IIB NSCLC was appropriate in terms of oncological outcomes. Visceral pleural invasion was the only prognostic factor in patients with eighth-edition stage IIB NSCLC.
