This paper attempts to examine the establishment, pattern and meaning of King’s Yeon and Hyang before the institutionalization of them in the early Joseon. In this study, I have three points which are the problems of the establishment and practice of King’s Party in the late Goryeo, the background of new directions for improving them and the establishment, contents and meaning of Yeon and Hyang. I have come to the conclusion of this study. In the early Joseon, King’s Yeon and Hyang was discussed as the alternative for the King’s Party of the late Goryeo which was lackadaisical, extravagant and disordered. Therefore, Yeon and Hyang were thought as the affairs which practiced friendship between the king and the subject centered respect and faith, ethical training and harmony. The Buddhistic ceremonial parties were eliminated. Yeon and Hyang had influence on building fidelity and order between the king and the subject, the relatives of king and meritorious retainers. They also had influence on the league, the normalization of relationship with Ming China through Sadae(Respect for the strong foreign country and its culture) banquet and the propagation of the spirit and order of Yeon and Hyang. Eventually, King’s Yeon and Hyang in the early Joseon had meaning as the communication scene between king and noble men and the pleasant gathering in which virtues and morals between them came true. It was very helpful to make harmony and order between kings and subjects in the early national founding period. 본 연구는 조선 초 제도화되기 이전 국왕 宴享의 성립 과정과 유형, 의미 등을 파악하기 위한 시도이다. 이를 위해 본 연구에서는 크게 세 가지 방향으로 나눠 분석해 보았다. 고려 말 국왕 잔치 설행에 나타난 문제점과 이를 개선하고자 나타난 새로운 방향의 모색, 그리고 宴享의 유형과 양상 분석이 이에 해당하였다. 결론을 요약하면 다음과 같다. 조선 초기 국왕 연향은 安逸과 奢侈, 無道 등 문란해진 고려 말의 국왕 잔치를 대신하는 것으로 논의되었다. 이에 따라 연향은 敬과 信을 중심으로 親을 행해 도덕적 수양과 실천, 和樂을 행하는 대상으로 여겨졌다. 따라서 불교의례 잔치는 혁파되었다. 즉, 군신간의 예의와 질서, 화락을 형성하는 ‘宴享’으로의 방향 모색이 이루어지면서 연향은 鹿鳴에서의 君子 嘉賓과의 만남, 德이 만나 和樂하며 큰 교화가 이루어지는 자리로 이해되었다. 그리고 실제 행해진 연향 중 君臣은 음식의 예로 만나면서 군신간 의리와 질서, 화락을 이룰 수 있었다. 이처럼 조선 초기 국왕 宴享은 敬과 信을 중심으로 親을 행해 도덕적 수양과 실천을 행하는 자리였다. 결국 조선 초 국왕 연향은 국왕과 현량의 만남이 이루어지는 소통 공간으로서의 의미가 형성되었고, 상하의 정이 통하며 덕과 도가 이루어지는 慶會의 자리로서 받아들여져 설행되었던 것이다. 이는 건국 초 君臣의 질서와 화합 등에 크게 기여한 측면이 있다 하겠다.

제 2족지 근위 지골에 발생한 저악성도 골육종 - 증례 보고 -

한정수,정덕환,신동준,임양선,정찬종,Han, Chung-Soo,Chung, Duck-Hwan,Shin, Dong-Jun,Lim, Yang-Sun,Jung, Chan-Jong 대한근골격종양학회 2001 대한골관절종양학회지 Vol.7 No.4

족부에 발생하는 골육종은 전체 골육종의 0.2~2%로 매우 드물며 장관골의 골간단부에 발생하는 저악성도 골육종은 전체 골육종의 약 1.9% 정도를 차지하는 드문 종양이다. 본 교실에서는 제 2족지 근위 지골의 종물과 심한 동통으로 내원한 38세 여자 환자에서 발생한 저악성도 골육종 1례를 경험하였다. 환자는 단순 방사선 검사상 좌측 제 2족지 근위 지골 전체를 침범한 골용해성 병변이 관찰되었으며 피질골은 얇고 팽대된 소견을 보였다. 골주사 검사상 단순 방사선 사진에서 보인 것과 동일한 위치에 흡수 증가의 소견을 보여 양성 골종양으로 판단하고 종양 절제 후 늑골을 이용한 관절 재건술을 시행하였다. 수술 후 조직학적 소견상 저악성도 골육종으로 판정되었고 이차적으로 좌측 제 2족지의 근치적 광범위 절제술을 시행하였다. 제 2족지 근위 지골에 발생한 저악성도의 골육종은 매우 드문 종양으로 광범위 절제술 후 좋은 결과를 얻었기에 문헌 고찰과 함께 보고하는 바이다. 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.

Purpose : To evaluate the neurologic abnormalities in the donor limb after contralateral C7 transfer in brachial plexus injury. Materials and Methods : From August 1996 to December 1999, five patients with brachial plexus injury were treated with contralateral C7 nerve root transfer. The average follow up was 16 months(range, 5 to 36 months). The clinical findings were assessed using the British Medical Research Council Grading System, and also measured grip power, pinch power of hand and two point discrimination of the fingers. Results : We had no difference in shoulder abduction and elbow flexion after contralateral C7 transfer. The grip and pinch strength were recovered within 4weeks. Sensory loss occurred in all patients and was noted to be more severe on index and middle finger. Four patients recovered within 2 weeks, one continued till one year. Subjective numbness and pain on percussion minimally persisted until last follow-up. Conclusion : The division of the C7 nerve root resulted in minimal and temporary functional deficit in the donor upper limb.

Introduction : The Functional muscle transfer is used to reconstruct the injuried muscle and paralysis of the shoulder. Especially transfer of the trapezius has been the treatment of choice but it has disadvantages of inadequate function and deformed contour, and instability of humeral head in case of acromion resection. We report an operation for shoulder reconstruction after wide resection of malignant fibrous histiocytoma, using rotational latissimus dorsi flap and review the operation method and clinical outcome. Materials and Methods : A patient, 53 year old, with malignant fibrous histiocytoma in the acromioclavicular joint area had been underwent wide excision, including the deltoid, clavicular head of pectoralis major, part of trapezius, lateral 1/3 of clavicle and acromion including scapular spine. The rotational latissimus dorsi flap with its neurovascular pedicle was dissected and then placed over the resected area and transfer of muscle attached at coracoid process was done to achieve stability of the humeral head. The range of motion of the shoulder and test of muscle power were evaluated for functional outcome. Total follow-up period is 2 years 11 months. Results : At last follow-up, the range of motion of the shoulder is abduction $90^{\circ}$, flexion $90^{\circ}$, internal rotation $40^{\circ}$, external rotation $50^{\circ}$ and the muscle power is 4 grade in all direction and then we obtained good functional results. There are no complications such as instability or subluxation of the humeral head and deformed contour and he is a disease-free survival state. Conclusions : The transfered latissimus dorsi flap provides adequate lever arm and stabilization and covering of the humeral head by sufficient muscle volume and width. This procedure can be useful not only for the paralysed deltoid reconstruction but also for use in reconstructive surgery after wide resection of the shoulder for malignant tumor.

Microtunneling techniques play a crucial role in the construction of pipelines. In this paper shows the automatic tunneling algorithm of microtunneling system by using fuzzy logic technology to assist operators assuring the quality of microtunneling construction. To have effective output value of fuzzy controller, we slightly modified the conventional defuzzificaton methods. The proposed automatic tunneling algorithm shows good tunneling results comparable with those of experts. 본 논문에서는 터널 굴진기의 모든 조작이 시스템 운용자에 의해 수동으로 운용 되고 있는 방법을 개선하여 터널 굴진기의 토크/추력 및 송/배니압을 자동으로 제어하는 방법을 제안한다. 이를 위하여 본 연구에서는 굴진 운용자의 토크/추력 및 송/배니압의 수동 제어 방법에 대해 체계적인 분석을 하였고 이를 바탕으로 퍼지 제어기와 경고 및 긴급 정지를 위한 제어기를 설계하였다. 제안된 시스템은 전문가 규칙으로부터 퍼지 규칙을 추출하였기 때문에 시스템 운용자들의 숙련된 제어 방법을 그대로 따르면서 시스템의 변화에 신속하게 대응 할 수 있다. 따라서 복잡한 환경에서 전문가의 역할을 대신할 수 있으며 기존에 운용자의 인지능력의 한계로 인해 시스템의 상태 변화에 빠르게 대응하기 어려웠던 점을 해결할 수 있다.

Purpose : Various free flaps and pedicled island flaps are effective for reconstruction of soft tissue defect developed after tumor excision. We want to know the advantage of dorsalis pedis island flap for reconstruction of soft tissue defect caused by soft tissue tumor excision. Materials and Methods : Between 1992 and 2002, we performed 4 dorsalis pedis island flap procedure for reconstruction of soft tissue defect of lower limb developed after soft tissue tumor excision. Average age was 54.7 years old $(40{\sim}68)$, and male 2 cases, female 2 cases. The kinds and number of soft tissue tumors were 2 squamous cell carcinoma and 2 malignant melanoma. The procedures that we performed were all dorsalis pedis island flap. The analysis for the result of treatment was retrospectively accessed by physical examination and questionnaire for whether the change of symptom after operation, range of adjacent joint motion. Also we reviewed associated complication after operative treatment. Results : All dorsalis pedis island flaps were alive. There is no problem for activity of daily living, no skin necrosis and no limitation of motion of adjacent joint. In 1 case of them, the patients died of distant metastasis. Conclusion: Dorsalis pedis island flap procedure as a pedicled island flap procedure is very effective and easy operative procedure for reconstruction of soft tissue defect of lower limb developed after tumor excision compared to free flap procedure because there is no need for microvascular surgery, we can obtain relatively large flap and the lesion and flap donor site locate in the same limb.

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.
