The Korean Classic Literature is closely related to the sentences of Korean Civil Service Examination at the days of the Korea and Lee Dynasty. because the men of letter of those days were selected into the proper authorities only through the Examination. Because of this reason, those sentences have been treated as an invaluable one in the literature world up to now. But no one can deny that those sentences have been criticized to the high level in the point of its technique. In considering those conditions, the writer described the kinds, the forms, the tendency of test, and the literary meaning in this paper.

권재혁,박병수 三陟大學校 1999 論文集 Vol.32 No.2

Feasibility of using the mixture of a wastewater sludge and additive as liner and the cover materials in disposal landfill. Granite weathered soil flyash, produced as a by-produced as a by-product in the power plant, were used as the primary additives to improve geotechnical engineering properties of sludge. For secondary additives, bentonite and cement were mixed with sludge to decrease the permeability and to increase the shear strength, irrespectively. Various kinds of laboratory test, required to evaluate the design criteria for the liner and the cover materials, were carried out by changing the mixing ratio of sludge with the additives. Basic soil property tests of specific gravity, grain size distribution, the liquid and the plastic limits were performed to evaluate their properties and to analyze their effects on permeability, compaction of mixtures. Various test results with mixtures were assessed to evaluate whether their properties met the requirements as the liner and the cover materials in waste disposal landfill.

콘트롤 로딩 시스템의 강인한 힘 제어기 설계

나병철,황재혁 한국 항공대학교 항공산업기술연구소 1999 航空宇宙産業技術硏究所 硏究誌 Vol.9 No.-

본 논문에서는 DC모터를 이용하여 실제 항공기에서 발생하는 조종반발력을 시뮬레이터의 조종간이나 페달에 실시간으로 구현시켜주는 힘 제어기법에 대해 연구하였다. 시뮬레이터의 각 조종축은 독립적으로 조종력을 구현할 수 있으므로, 본 논문에서는 피칭축 1축에 대해서만 힘 발생장치의 동특성을 고찰하였다. 실제로 역동역학을 이용한 제어기는 실시간으로 계산하는 과정에서 오차가 발생하고, 플랜트의 모델링 오차가 존재하므로 이런 부분에 강인한 힘 제어기를 설계하게 되었다. 힘 제어기는 슬라이딩 모드 제어기법으로 이용하여 파라메타 불확실성과 외란에 강인한 제어기와 콘트롤 로더의 명령추종 성능 향상과 안정성에 대한 강인성을 향상시키기 위해 앞먹임 제어기와 비례적분형 피드백 제어기로 구성되어 있다. 봅 연구에서 설계된 제어기는 명령추종 성능이 우수하고, 모델링 오차에 대해 강인한 특성을 갖고 있음을 수치해석을 통해 확인할 수 있다. In this thesis, a Robust force controller which provides the same wheel forces or pedal forces in real time to the student pilot in a flight simulator as those occurred during real flight has been suggested. Since the control force of each axis of simulator can be implemented independently, dynamic characteristics for only pitching axis in this study is analyzed. The novel force controller is designed using sliding mode control that is insensitive to the variation of force generating system parameters and/or external disturbances and updates the control forces appropriately in real time. The force controller consists of two parts. First part is designed to be insensitive to the effect of parameter uncertainty using sliding mode control and Second part is to improve the command following ability and robustness of system stability. It has been found by a series of simulation that the force controller suggested in this study has excellent command following ability and robustness to parameter errors

매복된 상악 중절치의 교정적 처치를 통한 치험례

김남혁,김성오,송제선,손흥규,최병재,이제호,최형준 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.1

매복은 임상 검사나 방사선 사진 검사 상에서 인식 가능한 맹출 경로 상에 장애물이나 이소 위치에 의한 치아 맹출의 정지를 의미한다. 상악 중절치의 치아 매복의 원인으로는 과잉치, 치아종, 치배의 이소위치, 외상 후 연조직 치유에 의한 폐쇄, 만곡치, 정지된 치근 발육 등이 있다. 매복된 치아는 인접치의 근심이동으로 인한 공간 상실, 부정교합, 인접치의 치근 흡수, 낭종의 형성 등을 유발할 수 있으므로 맹출장애에 대한 주의 깊은 관찰과 조기 진단이 중요하며 적절한 치료가 시행되어야 한다. 매복된 치아의 치료방법으로는 유치의 발거나 외과적 노출을 통한 맹출 유도, 경과관찰, 외과적 방법이나 교정력을 이용한 매복치의 재위치, 매복치의 외과적 발거 등이 있다. 이 중 교정적 견인은 매복된 치아가 원인을 제거한 후 또는 외과적으로 치관을 노출시킨 후에 일정기간의 관찰에도 맹출하지 않거나, 맹출경로가 정상에서 많이 벗어나 맹출이 기대되지 않을 경우 적용될 수 있다. 본 증례는 매복된 상악중절치를 교정적 견인을 통해 정상적인 맹출 방향으로 유도한 치험례들로 양호한 치료 결과를 보였기에 이를 보고하고자 하는 바이다. Impaction is defined as a cessation of the eruption of a tooth caused by a clinically or radiographically detectable physical barrier in the eruption path or by an ectopic position of the tooth. The reasons for impaction of the maxillary central incisor are supernumerary tooth, odontoma, ectopic position of tooth germ, dilacerated tooth and so force. Impacted tooth cause space loss due to proximal movement of adjacent tooth, malocclusion, root resorption of adjacent tooth, cyst formation, so careful observation and early detection is important and exact treatment should be applied to prevent these results. The treatment options of impacted tooth include induction an eruption through extraction of deciduous tooth or surgical exposure, reposition of impacted tooth by surgical method or orthodontic treatment. Orthodontic traction is recommended when an eruption does not happen after removal of barrier or surgical exposure, when eruption path is too transpositioned to be corrected spontaneously so eruption does not expected. In these cases, traction of impacted maxillary central incisor was carried out using orthodontic method with closed eruption technique and it showed good clinical results so we report these cases.

Desmoplastic trichilemmoma is a rare variant of trichilemmoma characterized by typical features of trichilemmoma with abundant desmoplastic stroma. We report herein a 54-year-old man presented with 2-year history of a solitary bean sized verrucous nodule on the occipital scalp. Histologically, the tumor showed a well-defined lobular growth extending from the epidermis into the dermis with abundant central desmoplastic stroma. Epithelial lobules at the margins of the neoplasm showed the typical features of trichilemmoma composed of glycogen-rich clear cells and peripheral palisading columnar cells. In contrast, at the center the cells assume a more random pattern of cords and strands traversed by the hyaline stroma, mimicking invasive carcinoma. It was diagnosed desmoplastic trichilemmoma by the distinctive histologic appearance and totally excised. (Korean J Dermatol 2003;41(1) : 120∼122)

Otitis media with effusion (OME) is one of the most common disease in children but its pathogenesis is not clear. In particular the role of allergy has revealed conflicting support with widely varing opinions as to its importance. Within recent years, striking biochemical and immunochemical analytic techniques have opened a new approach the study of otitis media with effusion. So we focused on distributions of IgE in adenoid tissue and serum IgE levels. Authors compared the serum IgE and the distribution of IgE in adenoid tissue between the 20 patients underwent tonsillectomy, adenoidectomy and ventilating tube insertion and control group of 11 patients underwent tonsillectomy and adenoidectomy. The results were as follows; 1. In the distribution of IgE in adenoid tissue, there was a significant increase in the group of patients with OME compared to the control group (P<0.01). 2. In the analysis of serum IgE levels, the levels of IgE in the OME patients an control group were higher than normal level, although the level of IgE in the OME patients were less than that of control group, there was no significance P>0.05).

儒敎的 自然法論에 관한 硏究

黃革周,金柄大 朝鮮大學校 法政大學 1974 法政大論文集 Vol.2 No.-

The natural law theory of the confucianism was a traditional legal thought in the agricultural society of the ancient orient. but, owing to the stagnation of the oriental culture, the above thought had ruledthe oriental society till the middle of the 19th century and the confucian notion is making fundation in forming up the oriental way of thinking. The basis of the thought is rationalism as "cheon(god, heaven) and reason. however, the contents of the thought represented by the confucianists were not reasonable. Confucius suggested wisdom, goodness and bravery as the contents of the natural law, and mencius the three bonds and the five moral rules in buman relations, and goodness, justice, courtesy and wisdom. The contents of the natural law theory are as follows : it was 1. directed to a patriarch oriented family system. 2. a ranking order which regarded men as the inequal relations. 3. authoritative and autocratic. 4. lacking in notions on freedom and right. Such concepts of the natural law not only gave rise to law-despising mind, but also deprived men of democratic volition. Now re-establishment as modern legal thought are required through duly criticizing the confucian natural law doctrine.

감압술을 이용한 치근단 낭의 처치

김남혁,최병재,이제호,손흥규,김성오,최형준 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.2

치근단 낭은 염증 등에 의한 자극으로 치수가 실활되어 치근단에 있는 상피로부터 형성되는 낭종으로 주된 기원은 말라세즈 상피잔사이지만 치은열구 상피나 상악동 이장 상피, 누공의 상피에 의한 것도 보고 되었다. 구강악안면 영역에서 가장 흔히 발생되는 낭종의 하나이지만 유치열기에서의 발생 빈도는 낮은 것으로 알려져 있다. 악골 내의 치성 낭종은 크기가 커지면서 주위 조직의 파괴나 구조의 변형을 초래할 수 있으며 유치의 경우에서는 후속 영구치배의 변위를 유발할 수 있다. 이런 큰 크기의 치성 낭종을 외과적으로 제거하면 해부학적 구조의 손상 및 안모의 변형, 치아흡수, 신경손상 등의 후유증을 일으킬 수 있으므로 조대술이나 감압술 후 적출하는 술식이 권장되고 있다. 이 증례는 하악 우측 부위의 동통을 주소로 연세대학교 치과대학병원 소아치과에 내원한 8세 남아로, 임상 및 방사선학적검사 결과 치수치료 후 기성금속관의 수복을 시행한 하악 우측 제1유구치의 치근단 하방에 방사선투과성 병변과 견치와 제1소구치의 변위를 발견하였다. 병소가 있는 하악 우측 제1유구치를 발거하였고, 조직학적 검사에서 치근단 낭으로 진단되었다. 감압술 및 공간유지장치를 시행하고 병소의 크기 변화와 하악 우측 견치와 제1소구치의 맹출 양상을 정기적으로 관찰한 결과 양호한 치유 양상과 정상적인 맹출을 보였기에 이를 보고하고자 한다. Radicular cyst is a true epithelium lined cyst formed when epithelium at the apex of a nonvital tooth is stimulated by inflammation. It is the most common type of cyst in the oral cavity, but its frequency is low in the primary dentition. Treatment of large-sized cyst aims at conservation of adjacent structure and allowance of proper eruption of the successive permanent teeth in the primary dentition. Considering these two aspects, marsupialization or enucleation following decompression is recommended as a treatment means for large-sized radicular cyst. In this case, 8-year old boy visited the pediatric dentistry department, Yonsei University Dental Hospital, with the chief complaint of pain on the lower right area. Clinical and radiographic examinations revealed periapical radiolucent lesion on #84, which had previous pulp treatment and restorated with the stainless steel crown. Dislocation of its successive tooth, #44, was also observed. #84 was extracted and sent for biopsy. Through histologic examination, it was diagnosed as radicular cyst. Following its extraction, removable space maintainer was delivered, which was also used as a decompressor. During periodic check-up for next 22 months, favorable healing of the lesion and eruption of the successive tooth were observed.
