The posterior cruciate ligament is an anatomically and biomechanically complex structure. PCL injuries are reported to occur in 1-40% of acute knee injuries, with isolated PCL tear, less common than PCL tears combined with other Iigament injuries. Controversy exists concerning the geatment of the PCL injures. Recently, arthroscopic techniques of PCL reconstruction are becoming nore refined and reproducible. Between July 1993 and May 1995, 25 operations for PCL rupture were performed in our hospital. At the follow-up examinations we noted mild to moderate posterior instablilty which was not noted at the time of operation and during the immediate postoperative period. We reviewed type (if injuries, amplitude of initial posterior tibia1 translation, surgical techniques, which seemcd to be in relation ivith the postoperative instabilities. At final follow-up, the mean Lysholm knee score was 86 points, and the posterior tibial translation 6.5mm on posterior stress radiographs. The ligament augmentation device provided no benefit. The ideal positioning and fixation of the graft and protection of the graft from abrasion seemed to be important to get a good results.

원숭이 외측슬상체배측핵에서 칼슘결합단백 Parvalbumin과 Calbindin-D 28K의 분포

고승희,배춘상,박성식,Ko, Seung-Hee,Bae, Choon-Sang,Park, Sung-Sik 한국현미경학회 1994 Applied microscopy Vol.24 No.4

The calcium-binding proteins (CaBP), parvalbumin (PV) and calbindin-D 28K (calbindin) are particularly abundant and specific in their distribution, and present in different subsets of neurons in many brain regions. Although their physiological roles in the neurons have not been elucidated, they are valuable markers of neuronal subpopulations for anatomical and developmental studies. This study is designed to characterize dorsal lateral geniculate nucleus (dLGN) neurons and axon terminals in terms of differential expression of immunoreactivity (IR) for two well-known CaBPs, PV and calbindin. The experiments were carried out on 6 adult monkeys. Monkeys were perfused under deep Nembutal anesthesia with 2% paraformaldehyde and 0.2% glutaraldehyde in 0.1M phosphate buffer. After removal, the brains were postfixed for 6-8 hr in 2% paraformaldehyde at $4^{\circ}C$ and infiltrated with 30% sucrose at $4^{\circ}C$. Thereafter, they were frozen in dry ice. Serial sections of the thalamus, at $20{\mu}m$, were made in the frontal plane with a sliding microtome. The sections were stained for PV and calbindin with indirect immunocytochemical methods. For electron microscopy, after infiltration with 30% sucrose the blocks of thalamus were serially sectioned at $50{\mu}m$ with a Vibratome in the coronal plane and stained immediately by indirect ABC methods without Triton X-100 in incubation medium. Stained sections were postfixed in 0.2% osmium tetroxide, dehydrated and flat-embedded in Spurr resin. The block was then trimmed to contain only a selected lamina or interlaminar space. The dLGN proper showed strong PV IR in fibers in all laminae and interlaminar zones. Particularly dense staining was noted in layers 1 and 2 that contain many stained fibers from optic tract. Neuronal cell body stained with PV was concentrated only in the laminae. In these laminae staining was moderate in cell bodies of all large and medium-sized neurons, and was strong in cell bodies of some small neurons together with their processes. Calbindin IR was marked in the neuronal cell body and neuropil in the S layers and interlaminar zones whereas moderate in the neuropil throughout the nucleus. Regional difference in distribution of PV and calbindin IR cell is distinct; the former is only in the laminae and the latter in both the S layer and interlaminar space. The CaBP-IR elements were confined to about $10{\mu}m$ in depth of Vibratome section. The IR product for CaBP was mainly associated with synaptic vesicle, pre- and post-synaptic membrane, and outer mitochondrial membrane and along microtubule. PV-IR was noted in various neuronal elements such as neuronal soma, dendrite, RLP, F, PSD and some myelinated or unmyelinated axons, and was not seen in the RSD and glial cells. Only a few neuronal components in dLGN was IR for calbindin and its reaction product was less dense than that of PV, and scattered throughout cytoplasm of soma of some relay neurons, and was also persent in some dendrite, myelinated axons and RLP. The RSD, F, PSD and glial elements were always non-IR for calbindin. Calbindin labelled RLP were presynaptic to unlabeled dendrite or dendritic spine and PSD. Calbindin-labeled dendrite of various sizes were always postsynaptic to unlabeled RSD, RLP or F. From this study it is suggested that dLGN cells of different functional systems and their differential projection to the visual cortex can be distinguished by differential expression of PV and calbindin.

고승희(Seung-Hee Ko) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.12

본 연구는 충청남도 직영기업을 대상으로 지방공기업 경영평가의 수용성을 분석하였다. 이를 위해 지방공기업 경영평가와 관련하여 5개 측면으로 영역을 구성하고 지방공기업 경영평가의 수용성과의 영향여부를 분석하였다. 직영기업은 조직 구조상 다른 공기업들과 다른 형태를 지니고 있어서 경영평가가 효율적으로 운영되기 위해서는 보다 차별화된 전략이 필요시 된다. 상하수도의 경우 지방자치단체 조직으로 경영평가 결과의 환류가 어려운 특징이 있어 관리자의 관심과 노력이 필수적으로 요구된다. 또한, 경영평가를 통한 직영기업의 성과를 높이기 위해서는 담당자의 전문성이 필요시 되는 만큼 이를 위한 정책적 운영방안이 필요시 된다. 무엇보다 경영평가 결과에 대한 인센티브가 다른 공기업처럼 의도한 효과를 내기 어려운 구조에 있다. 따라서 평가결과에 대한 보상시스템에 대한 차별화가 필요할 것이다. 본 연구의 한계가 있으나 상대적으로 특성이 다른 상하수도 관계자에 대한 의식조사가 이루어진 만큼 향후 경영평가제도의 운영방향을 모색하는데 기여할 수 있다는 것에 의의를 지닌다. This research analyzed acceptability of local public enterprise management assessment targeting Chungcheongnam-do direct management enterprises. To do this, this research analyzed influence with acceptability of local public enterprise management assessment by composing the area with 5 aspects related to local public enterprise management assessment. More differentiated strategy is required to operate management assessment efficiently, since direct management enterprises have different shape from other public enterprises in respect of organizational structure. In case of water and sewage, it tends to be difficult to return the result of management assessment to the local government organization, so that managers interest and effort is necessarily required. Also, responsible persons professionalism is required to raise achievement of direct management enterprise through management assessment, politic management plan for this is necessary. Above all, the structure of incentive for management assessment result is difficult in making intended effect as other public enterprises. Therefore, differentiation of compensation system for assessment result is required.

The present paper is the preliminary study of the development of a morphing aircraft wing and investigates experimently the aerodynamic characteristics of a base airfoil and a morphing airfoil. The wind tunnel tests are conducted for a base Clark-Y airfoil, an airfoil with a mechanical flap, and a morphing airfoil. Lifts, drags, and pitching moments are measured by using a three-axis load cell and they are calibrated by considering solid blockage and wake blockage. The wind tunnel tests are conducted for various air speeds, Reynolds’ numbers, and angles of attack. The experimental results show that the aerodynamic characteristics of the morphing airfoil in lift-drag and lift-pitching moment are better than those of the airfoil with a mechanical flap.

This thesis deals with the evaluation methods of Chinese character as a subject in middle school. Most of the traditional evaluation methods have been multi-choice types or short-answer types and had more focuses on memorizing fragmentary knowledge, which has lowered students interests in the subject and failed to achieve the ultimate purpose of Chinese character education. The purpose of this study is to improve the traditional evaluation methods. This thesis is primarily divided into two parts. First, the problems in the evaluation patterns are pointed out, on the basis of analyses of the existing evaluation methods in middle school textbooks. Second, new evaluation methods of Chinese character education in middle school are suggested. The evaluation methods suggested in this thesis have the following features. Fist, these methods can be applied to the lessons in the classroom as part of teaching, so that they can raise the efficiency of learning. Second, interesting factors are added to the methods and the methods are varied so that they can stimulate students interests in and motives on Chinese character study. Third, the methods develop students ability to use Chinese characters in their daily life. Forth, the methods develop students thinking faculty and originality. A pedagogical theories on evaluation methods of Chinese character as a subject is not yet established. Accordingly, this study has certain limits resulted from the fact that little precedent theoretical bases exist. And classes per week to practice these methods which researcher suggested are not enough. In this thesis, however, new types of evaluation method are suggested, which are expected to make a contribution to the practical side of Chinese character education. Furthermore, it is the researcher`s hope that more systematic study on the evaluation methods of Chinese character shall be carried out.

고승희(Ko, Seung-Hee),조성(Cho, Seong) 한국민간경비학회 2021 한국민간경비학회보 Vol.19 No.5

본 연구는 경찰법 개정안의 통과를 앞두고, 향후 자치경찰제도의 도입과 운영의 활성화를 위한 지방정부의 방안을 제안하는데 목적이 있다. 국가 전체의 치안총량과 현재의 안정적 경찰활동 체계의 유지를 위한 노력의 일환으로 실시되는 자치경찰제도의 가치에도 불구하고 새로운 제도 시행으로 인한 지방자치기관의 민주적 정당성 약화와 지휘․감독체계의 혼란, 지방행정과 치안행정의 연계 및 지역특성의 반영 측면에서 한계가 있기에 수정, 보완 및 시범실시 등을 통하여 부작용을 최소화 하여야 한다. 현행 법령에서 제시하고 있는 주요 쟁점과 논의되고 있는 사항들은 자치경찰제에 대한 책임자로서 시․도지사의 실질적 권한과 자치경찰의 자율적 운영에 대한 가능성, 시․도 자치경찰위원회와 사무기구에 대한 자율성, 시․도지사의 지휘감독권과 인사권 및 법률안 의견 제출권 등으로 정리될 수 있다. 자치경찰제 운영을 위한 광역자치단체 차원의 추진과제는 자치권과 관련된 과제와 자치경찰제의 준비를 위한 과제들로 나누어 볼 수 있는데, 대외적 과제로서 국가경찰위원회의 자치경찰 관련 전문성을 확보하고 시․도 경찰위원회 구성에 있어 시․도지사의 권한을 확대하며 시․도 경찰청 임명에 대한 시․도지사의 권한 확대와 국가지원의 확대, 사무기구 운영의 자율성 보장 등을 제시할 수 있으며, 내부적으로는 가칭 ‘광역권자치경찰추진단’을 구성하여 지방경찰청과 공동으로 사무를 구분하고 인력과 예산을 도출하는 등 사무기구의 운영방안을 확정하는 과정이 필요할 것이다. The purpose of this study is to propose a plan of local government for the introduction and operation of the autonomous police system in the future, ahead of the passage of the amendment bill of the police law. The 21st National Assembly should minimize the side effects through revision, supplementation and demonstration because it is part of the efforts to maintain the total amount of security of the whole country and the current stable police activity system, weakening the democratic justification of local autonomous agencies, confusion of command and supervision system, linkage of local administration and security administration, and reflection of local characteristics. The main issues and issues discussed in the current bill can be summarized as the actual authority of the city and provincial governors as the head of the local police system, the possibility of autonomous operation of the local police, the autonomy of the city and provincial police committee and office, the command and supervision of the city and provincial governor, the right to submit personnel rights and the right to submit the opinion of the bill. The tasks of local authority for the operation of the autonomous police system can be divided into tasks related to autonomy and tasks for preparation of the Autonomous Police police system. As an external task, the expertise of the National Police Commission related to the self-governing police is secured, the authority of the city and provincial governors is expanded in the composition of the city and provincial police committee, The government should form a tentatively called Local Police Promotion Team to divide the affairs in cooperation with the local police agency, draw up manpower and budget, and prepare a plan for operating the office.

Purpose : Schulte introduced immediate implant cases in 1970s, since then many patients have been treated by immediate implants. The aim of this study was to evaluate the cumulative survival rate of immediate implant and to analyze various factors associated with survival of immediate implant in a 8-year period retrospectively. Materials and methods: From May, 2000 to October, 2007, 77 implants were placed in 63 patients immediately after tooth extraction at Department of Periodontology, Yonsei University Hospital. The implant survival rate was analyzed using a life-table analysis. After delivery of prosthesis, along I year of observation period, all implants were evaluated clinically and radiographically. Results: Among 77 implants, 59 were placed in maxilla and 18 in mandible. The most common site of the implantation was Mx anterior (65%). The overall survival rate was 94.8% over a mean follow-up period of 44.2±21 months and the 8-year cumulative survival rate was 94.6%. Failure occurred in 4 implants, all of which were due to early failures. None of the following factors were significantly associated with the survival of immediate implants: advanced surgical technique including bone graft and guided bone regeneration, the types of implants, causes of tooth loss, and types of prosthesis. Conclusion: On the basis of 8-year life time analysis, immediate implant placement can be considered a safe and predictable treatment mordality.
