  • Student halls and their convenient facilities have been a focal point for various student activities at university campus. It has been for most of the student a place of unique memories and of attachment often associated with those good and bad school days. However, it is questionable whether these facilities are supportive and accessible for all of the students and other users including the handicapped. Therefore, based on the concept of UD(universal design) which was widely applied to U.S. institutions, this study intended to evaluate student hall facilities in U.S. and to provide an improvement direction for Korean UD application. For that purpose, four universities were selected for an in-depth analysis and 76 survey indices were utilized based on previous research. It was found that (1) design consideration without braille sign for VIP(visually impaired person) in student buildings can be differently approached with electronic devices; (2) the best demonstration of UD in student buildings can be seen in spacious flat pathway, easy access through ramp and wide entry area, necessary for people in wheel-chairs, but used by all, implying an increase of the ratio of public space; (3) one of the good UD features is an attractive physical environment rather than institutional appearance, in which they ultimately will support and completely adaptable at optimal levels by everyone; (4) consistent maintenance and management maximize the potential of UD principles and minimize physical limitations.

  • Endoscopic resection (ER) is widely performed for early gastric cancer (EGC) with a negligible risk of lymph node metastasis (LNM) in Eastern Asian countries. In particular, endoscopic submucosal dissection (ESD) leads to a high en bloc resection rate, enabling accurate pathological evaluation. As undifferentiated EGC (UD-EGC) is known to result in a higher incidence of LNM and infiltrative growth than differentiated EGC (D-EGC), the indications for ER are limited compared with those for D-EGC. Previously, clinical staging as intramucosal UD-EGC ≤2 cm, without ulceration, was presented as 'weakly recommended' or 'expanded indications' for ER in the guidelines of the United States, Europe, Korea, and Japan. Based on promising long-term outcomes from a prospective multicenter study by the Japan Clinical Oncology Group (JCOG) 1009/1010, the status of this indication has expanded and is now considered 'absolute indications' in the latest Japanese guidelines published in 2021. In this study, which comprised 275 patients with UD-EGC (cT1a, ≤2 cm, without ulceration) treated with ESD, the 5-year overall survival (OS) was 99.3% (95% confidence interval, 97.1%-99.8%), which was higher than the threshold 5-year OS (89.9%). Currently, the levels of evidence grades and recommendations for ER of UD-EGC differ among Japan, Korea, and Western countries. Therefore, a further discussion is warranted to generalize the indications for ER of UD-EGC in countries besides Japan.

저온.고온고습 환경시험에 의한 GFRP의 미시계면 접착상태 및 노치형상강도 특성에 관한 연구 (A study on characteristic adgesive condition at microscopic interfaces and notch shape strength of GFRP composites laminates under low-hot-wet environment)

  • The purpose of this investigation is to estimate the strength with the variations of the notch shape and the adgesive condition at the fiber/matrix micro interface of E-glass/PP laminates. To promote the degradation of the adhesive condition at the fiber/matrix micro interface without matrix dissolution loss, low-, hot-wet and spiking tests were carried out. The absorpotion properties and the tensile properties were compared accrding to the fiber orientation and the content. The results show that, firstly, saturated moisture absorption was reached at 5cycles and their absorptions of RD-40, UD-42 and UD-50 are 0.68%, 0.63%, 0.60%, respectively. Secondly, all the specimens investigated were mostly degraded at 5cycle, whereas UD-50 having ellipse shaped notch the least decrement of strength.

  • 본 연구의 목적은 청주시의 주택문제에 대한 특별한 해결책을 논의한다기보다는 문제를 바라보는 새로운 프로세스를 형성하여 도시내부 문제해결을 위한 UD 모형을 적용하고 검증하는 것이다. 모든 도시는 성장과 쇠퇴의 주기가 있듯이 청주라는 공간도 현재의 물리적인 경계를 유지하면서 영원히 성장할 수 없으며, 성장의 한계에 이르게 되고, 시스템 내부의 피드백구조의 역동성에 의해 동태적인 균형상태를 지향하게 된다. UD 모형을 통해서 본다면 청주의 경우도 향후 50년간은 인구, 주택, 산업 모든 측면에서 성장을 이루게 될 것으로 보인다 2055년 이후에는 그 증가율이 정차 감소하여 균형상태를 유지하게 되다가 한 시점에 이르러서는 내부 stock 변수들의 인과관계에 의해 청주의 매력도는 주변지역으로 이전되게 될 것이다. 거시적으로 보았을 때 청주의 경우도 적정수준에서 이러한 추세를 따라가기 때문에 청주시의 UD 적용의 유용성은 입증되었다고 말할 수 있겠다. 더불어 민감도 분석에서 사용한 변수들의 조정에서 나왔듯이 주택과 관련된 정책을 펼칠 때, 시스템 내부적인 변수를 조정하는 정책을 펼쳐 나갈 때 청주라는 공간은 주택분야뿐 아니라 도시전체시스템의 동태적 균형상태를 유지해 나갈 수 있을 것으로 나타났다.

  • 초기의 영화는 그 당시에 현실을 있는 그대로 보여주는 도구로서, 인간의 현실을 표현하고자 했던 많은 도구들 중에서 유일했던 것이다. 하지만 시간이 지나고 TV의 발달과 더 나아가 케이블TV, 현재에는 인터넷과 개인 스마트모바일 디스플레이의 등장으로 그 기능이 상쇄되어 갔고, 이에 따른 영화 자체의 생존전략을 찾아가기 위해 공간적 측면에서는 '새로운 스크린'을, 구현하는 방식과 현실을 재현하는 측면에서는 영상처리의 '신기술'을 과거에서부터 현재까지 계속 이어진다. 하지만 현재 영화와 비슷한 기능을 하는 매체들이 많은 가운데, 이러한 신기술들이 공유하고자 하는 매체들도 늘어나게 되었고, 이제는 하나의 신기술을 누가 먼저 시현, 선점하느냐가 큰 관건인 상태에서 '영화'가 선택할 수 있는 향후 10년 후 기술들은 현재 진화하고 있는 디스플레이 측면에서 'UD(Ultra-Definition)'와 영상기술 측면에서는 'Head Tracking 3D' 일 것이다. 본 연구는 이 두 가지 기술에 의해 영화산업의 미래를 기능적, 경제적인 측면으로 전망해 보았다.

  • This study is about the effect of braiding on the 2-D biaxial braided hollow composite(BD) compared with unidirectional hollow composite(UD). The specimens were made of T700S Carbon/Epoxy prepreg and T700S dried Carbon yarns. Fiber volume fraction of UD and BD was obtained experimentally and analytically. Fiber volume fraction of BD was derived based on unit cell of braiding yarn section. Bending test was executed to investigate the effect of braiding part. The result of experiment and analysis of fiber volume fraction has good agreement. Bending strength of BD is about 20% higher than that of UD.

  • In this paper, we first show the weak convergence of the modified Ishikawa iteration process with errors of two total asymptotically nonexpansive mappings, which generalizes the result due to Khan and Fukhar-ud-din [1]. Next, we show the strong convergence of the modified Ishikawa iteration process with errors of two total asymptotically nonexpansive mappings satisfying Condition ($\mathbf{A}^{\prime}$), which generalizes the result due to Fukhar-ud-din and Khan [2].
