This paper deals with recent research cases and directions of Fly-By-Wireless (FBWLS) flight control technology. FBWLS is a new type of flight control system technology with the aim of solving the problems mainly caused by the increasing amount of wires in aircraft to which Fly-By-Wire (FBW) technology applies. Therefore, in FBWLS flight control system the wired communication system is replaced with a wireless communication system. Currently the FBWLS flight control technology is at an initial development stage and thus this paper surveys deals with the cases in the viewpoint of technology feasibility. In this context, this paper analyzes technology that needs further studies to secure the reliability, stability and accuracy to the similar level of the corresponding FBW system. Since the major problems of FBWLS technology are packet losses and time delays so that this paper suggests the research direction of wireless communication protocol selection, optimization of wireless communication network and controller design considered communication environment.

Injuries of wrist in upper extremity is common onset in industrialized world. The development of joint arthroplasty and mechanical joint is area of research for biomechanical engineer and surgeon for a decade. Therefore. the knowledge of characteristic of joint motion is essential to develop the artificial wrist joint. In this study. the joint motions of wrist required for activities of daily living (ADLs). including personal hygiene and care. and general home activity were measured using flexible electrogoniometer. Total of 25 different daily activities were separated into four groups and tested on 15 subjects who did not show any abnormality of their joint functions. The maximum functional range of motion required for ADLs were obtained and standardized for analysis and comparison. Also. a least functional range of motion for ADLs were investigated. Results revealed that any significant differences were not found in least functional range of motion between left and right wrist to perform ADLs. However. a significant difference was found in different ADLs. Therefore. least range of motion obtained in this study can be used as basic data to design artificial joint and set a goal for surgeon to achieve appropriate treatment from patients.

Purpose : Spine is one of the most common sites of the metastatic bone tumors. Conservative management such as chemotherapy or radiotherapy has been preferred in most cases. However, the neurologic deficit has not been usually improved, and the quality of life was poor. The purpose of this study was to show the efficacy of the surgical treatments for metastatic spinal tumors in terms of postoperative improvements of neurologic deficit and survival time. Materials and Methods : Authors have reviewed the literatures and analyzed 14 patients of metastatic spinal tumors who were received operative treatments between August 1991 and June 1999 at the our department of orthopaedic surgery. Results : The most frequent primary tumor was breast cancer in women and lung cancer in men. The thoracic region was the most common site. There was a preponderance of females over males, and the age ranged between 4th and 8th decade. The indications of surgical treatment comprised instability, progressive neurologic findings, resistance to radiotherapy, pathological fracture, long life expectancy( >6weeks), isolated metastasis and need for pathological diagnosis. The degree of preoperative neurological deficit might influence on the improvement of clinical symptoms after surgery. Conclusion : The surgical treatment reduced the neurological deficit and pain regardless of the operative methods. In the early stage of neurological deficit, the surgical treatment was important for better prognosis. Recently early active operative treatment was performed for metastatic spinal tumor to minimize the intractable pain and to prevent the progression of the neurologic deficit. Early intervention can improve the quality of life and long term survival.

The reported incidence of osteosarcoma of the foot varies between 0.2-2% of all osteosarcoma. Low grade osteosarcoma of the long bone represents only 1.9% of all osteosarcoma. A 38-year-old female had suffered painful mass in the proximal phalanx of the second toe for 1 year. Radiographic finding showed enlarged osteloytic mass which had penetrated thin cortex of the second toe and apparent increased uptake in bone scan was seen. Mass resection with autogenous bone graft using rib was performed. Histologically, the tumor was compatible with "low grade osteosarcoma". Second stage wide resection was performed. Because low grade osteosarcoma located in the proximal phalanx of the second toe is very rare, we report this unusual case with review of literature.

고려시대 태조 追慕儀의 양상과 崇拜

한정수(Han, Jung-Soo) 한국사학회 2012 史學硏究 Vol.- No.107

이 연구는 고려시대 태조 숭배의 양상과 그 의미를 정리하여 고려시대 왕조운영의 특징을 찾아보려는 것이다. 이를 살펴보기 위해 먼저, 왕실 혈통 및 태조의 탄생에 대한 신성화 내용을 검토하였다. 다음으로 태조 사후 전개된 태조 추앙 및 숭배의 양상에 대해 국가적 제사 즉 길례적제의(祭儀) 중 관련 내용을 정리했다. 마지막으로는 신앙 및 종교와 관련한 태조 숭배 내용 이해를 위해서 연등?팔관회, 태조소상 조성 및 진전사원 운영, 태조무재일 이해 등을 살펴보았다. 요약하면 다음과 같다. 먼저 태조 사후 지속적으로 추구된 태조 세계(世系), 탄생 등에 대한 신성화의 내용을 검토하였다.『고려세계』를 보면, 설화적 이야기를 통해 태조의 혈통을 신비화하고 있었다. 또 예언적인 풍수도참을 통해서는 태조를 삼한일통의 군주이자 용손(龍孫)의 뿌리로 상징화하였다. 나아가 성조화(聖祖化)를 통해 태조는 고려왕조의 상징으로 승화되기에 이르렀다. 이 같은 위상을 가진 태조는 원구의, 태묘의, 경령전 및 성용전, 현릉 등국가 제사를 통해 상제에 짝하는 배위이자 불천지주로서 자리매김되었다. 따라서 신성한 상징으로서 고려 국왕의 정기적 참알과 봉향의 대상이 되었다. 이와 함께 고려에서는 태조가 개최하기를 유언한 연등?팔관회를 가장 성대한 가례(嘉禮)로 행하였고, 태조를 상징하는 봉은사 진전 참알 및 봉향과 법왕사 행향 등을 친행하였다. 태조 추모와 숭배가 주기적으로 반복되면서 신앙화된 면이 나타난 것이다. 신성함의 상징인 태조소상과 진영이 조성되었고, 이를 중요 사찰에 봉안하기도 하였다. 태조가 행한 애민의 면은 기곡(祈穀)과 기양(祈禳)을 위한 기도의 승화 즉 태조무재일로 상징화되었다. 태조 숭배와 신앙이 만들어낸 바라 할 수 있다. 이처럼 태조 혈통, 태조 탄생 등은 당대의 기록과 후대의 수식을 통해 신성화되었다. 그리고 이는 다시 제사 및 신앙 종교 활동 속에서 주기적으로 재생산되었다. 태조 숭배와 신앙으로 이어진 것이다. 결국 이를 통해 고려는 용조이자 성조인 태조의 후손이라는 왕실 정체성과 통치의 당위성을 확립할 수 있었고, 이는 연등?팔관회 등에서 보이듯 사회통합의 원리가 되었다 하겠다. This paper attempts to arrange the aspects of commemorating ceremonies for Taejo(Goryeo’s first king) in the Goryeo period and search for the features of the management of the Goryeo dynasty by arranging that these ceremonies were transcendentalize to be some kind of cults and beliefs. For this purpose, firstly I examine the consecration of the royal blood and the birth of Taejo. Secondly, I arrange how the commemoration for Taejo reflected in the ancestral rites of national level. Finally, I try to find the commemoration for Taejo relating the belief and religion. By this process, I have come to some conclusion. The blood and birth of Taejo was consecrated by the records of that time and the emblazonment of late time. Taejo, who left Hunyo 10cho(10 injunctions for his successor to observe) and accomplished the unification of three Han, was reproduced periodically in the ancestral rites of national level and the activity for religion and belief as the divine progenitor. He was also the object of wish for national safety. From these phenomena, we can understand the meaning of the cult and religion for Taejo. Eventually Goryeo was able to establish the appropriateness of rule by the establishment of royal identity and authority from the fact that Taejo was the divine progenitor relating the dragon. As we can see in Yeondeunghoe(Lotus lamp ceremony) and Palgwanhoe(Assembly of Eight Prohibitions), it became one of the principle for the integration of society.

고려-송-거란 관계의 정립 및 변화에 따른 紀年의 양상 - 광종~현종 대를 중심으로 -

한정수 ( Jung Soo Han ) 한국사상사학회 2012 韓國思想史學 Vol.0 No.41

10세기 말에서 11세기 초 동북아시아의 국제질서는 송의 건국과 함께 고려와 거란, 거란과 송의 전쟁 속에서 송에서 거란으로 주도권이 바뀌었다. 이 속에서 고려는 거란에 대한 사대를 선택해야 했으며, 그에 따라 사대조공질서 중 한 축인 연호와 이를 적용한 기년 방식 역시도 변화를 겪었다. 이 같이 복잡한 양상은 10세기 말에서 11세기 초에 걸쳐 보이는 금석문 자료 및 『고려사』 세가에서 반영되었다. 이를 정리하기 위해 본고에서는 고려-송, 고려-거란 관계의 정립과 변화를 고려하면서 『고려사』와 금석문 자료를 중심으로 이 시기 기년 방식의 전개와 양상을 분석하였다. 결과는 다음과 같다. 송과 거란과의 국제관계 정립이 이루어지면서 고려가 선택한 공식적 기년 방식은 연호 기년이었다. 그러나 내부적으로는 국왕 재위 기년과 함께 간지 기년을 썼음이 확인된다. 광종~현종대 고려와 송, 고려와 거란의 국제질서의 전개 속에서 고려는 상대국의 연호를 받아들여 연호 기년을 적용하였지만 고려는 피휘 및 재위 기년 등을 통해 왕실의 존엄성을 확인하고자 한 것으로 보인다. 왕실 존엄성을 유지하고 세조와 태조 숭배의 인식 속에서 이들의 휘와 같은 글자인 ``建隆``을 피휘하여 ``峻豊``이라 한 점이 보이고 있는 것이다. 또한 광종~현종 대 연호 기년의 기본 내용은 반거란적 정서에 입각한 면이 커 송 중심 국제질서 아래 송의 연호를 사용하려 한 양상이 많이 나타났으며, 거란 연호 기년 방식에 착오가 많았던 것은 이를 보여주는 것이었다. 동시에 불교 유물과 승려 및 관인층의 금석문에서는 기년의 다양한 적용 방식을 알 수 있어 기년 문화의 다양성을 읽을 수 있었다. In the late 10th and early 11th centuries, Song was established in China and Song engaged in warfare with Khitan and Khitan engaged in warfare with Goryeo. Finally, Khitan took initiative in international order of Northeast Asia. In this situation, Goryeo should choose the policy of respect for the strong foreign country and its culture(Sadae) for Khitan. According to this choice, the way of the era name(Yeonho), which was one of the axes for the order of respect for the strong foreign country and its culture and tributary system, and the calender system(Ginyeon), which was influenced by the era name, changed too. We can see those complicated situations in epigraphic sources of late 10th and early 11th centuries and Goryeosa. By the analysis of them, we can understand the international relationship of Goryeo from Gwangjong to Hyeonjong and the position of Goryeo in using the calender system. In this study I try to analyze (1) the change of the calender system in accordance with the establishment of international relationship between Song and Goryeo, (2) the aspects of the ways of the calender system influenced by the interruption of relationship with Song and the establishment of international relationship with Khitan, and (3) the content and meaning of the ways of the calender system represented in epigraphic sources. With the establishment of Song, Goryeo chose the international order with Song as the center and accepted the era name and calender system of Song with Jeongsak. However, Goryeo accepted the royal succession(Chaekbong) and tributary system in the relation with Khitan after Goryeo-Khitan war, though they had negotiation process. Goryeo used the era name of Khitan too. While Goryeo followed international order oriented towards Khitan, Goryeo had unique character in using the era name and calender system internally. Goryeo pursued autonomy in adopting the self-regulating era name calender system, sexagenary calender system, reign year calender system and three times of sexagenary cycle (samwongapja) calender system.

고려시대 국왕 잔치의 양상과 그 성격

韓政洙(Han Jung-Soo) 歷史敎育硏究會 2011 역사교육 Vol.118 No.-

Royal banquets of Goryeo were fundamentally hosted by the king for virtuous men or for the people on felicitous occasions; the king would hold felicitous assemblies, which acted as a medium for the king of Goryeo to practice benevolent rule as part of the process of gaining/maintaining the king’s authority, grace, and harmony. These resulted in amicable unity. Through holding diverse types of banquets such as yeon(宴), gogyeon(曲宴), chiju(置酒), hyang(享), po(?), and hyang(饗), the king attempted harmony between his subjects and himself by upholding moral obligations and respect between ruler and subjects, order between the old and the young, and propriety toward others. Furthermore, the ruler tried to communicate with the people through provisions for the elderly and banquets for the people as well, of which there were so many varied types that these could be called “politics of banquets”. As can be seen from above, the various royal banquets of Goryeo are not only events where the sovereign bestowed benevolence and confirmed his authority, they also were significant for fostering harmony between ruler and his subjects and edifying the people.
