The Royal tomb Goe, deserves to be called a true representative of the Silla dynasty tombs; and, it has some key factors worthy of investigation and evaluation: 1. The foreign style of the two stone warrior statues at the tomb is that of a Saracen, who entered the dynasty as merchants from the Middle East through China. The costumes of the statues are not suits of armour, but those of Arab merchants, and were selected due to the Saracen influence on the court. The reason their stout, magnificent and exotic countenance was used on the statues was because it seemed to be desired to express grand appearances and imitate what was new at that time. 2. The postures of the four stone lion statues at the Royal tomb Goe belong to the same style as those of Sungduk and Heungduk. But the positions of the lions are different. The four lions are all in front of the south side of the tomb Goe, while they are in the four corners respectively in both tombs mentioned above. Under the supposition that the stone lion statues had been arranged in the four corners of the tomb, then further consideration of the postures matches to the supposition and leads to determine that the original positions should have been as the supposition directed. The fact that the system and style of the Royal tomb of Heungduk closely imitated those of the Goe, renders the criteria to analogize the original positions of the stone lion statues. That is to say that the four stone lion statues of the comb had been in, the four corners of the tomb when the Royal tomb of Heungduk was built, and were moved to the present positions later. Further the paragraph on the epitaph at the Soongbok-sa temple, "special protection was given to the Royal tomb of Wonsong in the reign of King Kyongmun," also enhances this probability. 3. The sequence of construction in the same style according to the tomb systems is as follows: Royal tomb of Sungduk-Royal tomb Goe-Royal tomb of Heungduk The age of the statues at the Goe, according to features, is assumed to be between the middle and later part of the 8th century. The close relations between the tomb Goe and the Royal tomb of Heungduk, as mentioned above, present the assumption that the tomb Goe is the resting place of King Wonsong (785-798), grandfather of King Heungduk. With the position of the Soongbok-sa temple, the protecting place of the tomb, confirmed, and with support from the other paragraph in the epitaph concerning the unique tomb, located on the lower ground, it can be concluded that the Royal tomb Goe is none other than the tomb of King Wonsong.
측두하악장애 증상으로 나타나는 구강안면부의 통증 및 개구제한 증상은 대부분 관련 구조물 자체의 구조적이거나 기능적인 변화에 의해 유발되지만, 드물게 다른 병적인 상태로 인하여 발생할 수도 있으므로 진단 및 치료에 있어서 주의가 요구된다. 특히 통증 양상 및 임상 소견, 전신적 동반 증상, 치료에 대한 반응 등에 대한 평가에서 두경부 종양과 같이 다른 질환에 의한 측두하악장애 증상이 의심되거나 일반적인 측두하악장애와 다른 소견이 나타나는 경우에는 전산화단층촬영 또는 자기공명영상 등의 부가적인 방사선학적 검사를 적극적으로 시행하여 부가적인 정보를 얻는 것이 필요하다. 본 증례에서는 측두하악장애 증상으로 내원하였던 비인두암종 환자의 진단 및 치료 과정을 통해, 측두하악장애의 진단 및 치료에 있어서 비인두암종 등 두경부 종양의 가능성을 고려해야 할 임상적 소견에 대해 고찰하고자 한다. Orofacial pain and limited range of mouth opening as symptoms of temporomandibular disorder are mainly triggered by the structural and/or functional changes of temporomandibular joint and related structure itself. But careful diagnostic evaluation should be needed because they may be occurred by another pathologic conditions such as neoplasm in head and neck region. If there would be atypical pain characteristics or clinical features, systemic comorbid symptoms, or poor response to treatment, advanced imaging modalities such as CT or MRI will be mandatory for differential diagnosis. We experienced the case which was diagnosed as nasopharyngeal cancer mimicking temporomandibular disorder, and reviewed clinical considerations for proper differential diagnosis.
This paper describes the procedure of development of a coaxial rotorcraft micro air vehicle for indoor surveillance and reconnaissance mission. The survey to provide a guide for preliminary design were conducted based on commercial off-the-shelf platform, and the rotor performance was estimated by the simple momentum theory. The modified fuel balance method which is adoptable for electric powered vehicle was applied to determine the initial size of the micro air vehicle, and it was optimized with sequential quadratic method. The developed vehicle shows stable handling quality with manual flight test in indoor situation. 본 논문에서는 실내 감시정찰 임무를 위한 동축반전 헬리콥터형 미세비행체의 개발과정을 기술하였다. 기본설계 방향을 제시하기 위해 상용 비행체의 제원을 조사하였고, 간단한 운동량 이론에 의해 공력 성능이 예측되었다. 미세비행체의 초기 사이징을 위해 전동 모터로 구동되는 비행체에 적용 가능한 수정된 fuel balance 기법이 적용되었고, sequential quadratic 기법에 의해 최적설계가 수행되었다. 개발된 비행체는 실내에서 수행된 수동조종 시험에서 안정된 조종성을 나타내었다.
본 논문에서는 웹기반으로 운용 가능한 해상안전 드론의 시스템 통합 및 기술시연 결과에 대해 기술하였다. 해수욕장 안전감시와 인명구조를 목적으로 광학 카메라와 투척식 구명의를 탑재한 소형 쿼드로터드론 플랫폼을 개발하였다. 실시간 영상전송을 위해 상용 LTE 망을 활용한 통신 체계를 구현하였고, 웹기반으로 운용되는 중앙통제 시스템을 구축하였다. 해상안전 드론은 2015년 7월 말부터 시험운항을 시작하였고, 현재 부산 해운대 해수욕장 일대를 중심으로 서비스를 수행 중에 있다. This paper describes the system integration and demonstration results of a web-based operational maritime safety drone. A small size quad-rotor drone platform was integrated with an electro optical camera and a throwable life jacket to support bathing beach surveillance and rescue mission. A communication link was implemented by using commercial LTE module to provide a real-time video streaming, and a web-based central command system was build up. Test flight of the maritime safety drone was started from the end of July 2015, and it is now on service mission in Haeundae beach at Busan.
Purpose: Only a few Asian studies have discussed the impact of statin intensity on clinical outcomes in patients with peripheralartery disease (PAD). We aimed to investigate the clinical impact of statin intensity in patients with PAD after endovascular revascularization. Materials and Methods: From April 2009 to June 2019, 376 patients with lower extremity PAD treated with endovascular revascularizationwere enrolled. They were classified into three groups according to statin intensity: no-statin, low-to-moderate intensity(LMI), and high-intensity (HI). The primary outcomes were major adverse cardiovascular events (MACE) and major adverselimb events (MALE). Results: During the 40-month follow-up, MACE occurred less frequently in the HI and LMI groups than the no-statin group(11.4% vs. 16.0% vs. 39%, p<0.001). In adjusted Cox models, the HI group had the fewest MACE [hazard ratio (HR): 0.447; 95%confidence interval (CI): 0.244–0.834; p=0.018] and MALE (HR: 0.360; 95% CI: 0.129–1.006; p=0.051) events, while the LMI grouphad fewer MACE (HR: 0.571; 95% CI: 0.326–1.0; p=0.050) events than the no-statin group. HI statin therapy was associated withbetter outcomes in terms of MALE (HR: 0.432; 95% CI: 0.223–0.837; p=0.003) than LMI statin therapy after inverse probabilitytreatment weighting analysis. Conclusion: HI and LMI statin use is associated with a significant reduction in MACE events than no-statin use. HI statin use wasassociated with better MALE outcomes than no-statin or LMI statin use.
