The purpose of this study were to investigate leadership life skills' relationship with youth circle activities participation variables and to examine the effects of youth circle activities participation on the leadership life skills. Data for this study were collected from 1,814 students in middle and high schools, and 1,808 responses were analyzed after data screening. The SPSS for Windows were used to analyze the data. Frequency, percentage, t-test, ANOVA, optimal scaling regression, and LSD test for post-hoc interpretation were employed to analyze the data with a statistical significance level of .05. The results were as follows: First, the results of ANOVA and t-test revealed that 7 youth circle activities patricipation variables(participating circle numbers, circle types, years in circle, leader or not in that circle, level of participation, level of satisfaction, level of supporting) influenced the youth leadership life skills. Second, As a result of optimal scaling regression analysis, these 7 variables accounted for 11.8% of the variance of youth leadership skills. And among these 7 variables, level of participation, level of supporting, and years in circle were identified as the comparatively important determinants of youth leadership life skills. 이 연구의 목적은 청소년 동아리활동의 효과를 검증하기 위하여 청소년 동아리활동 참여와 리더십생활기술의 차이를 검증하고, 청소년 동아리활동 참여가 리더십생활기술에 미치는 영향을 분석하는 것이었다. 이 연구의 대상은 동아리활동에 참여하고 있는 전국의 중·고등학교 청소년 1,808명이었다. 성별로는 남자 34.8%, 여자 64.8%이었고, 학교급별로는 중학교가 30.4%, 인문고가 44.3%, 실업고가 22.3%였다. 지역별로는 서울특별시가 32.6%, 광역시가 25.1%, 중소도시가 30.9%, 군지역이 10.6%였다. 조사도구는 청소년 동아리활동 참여관련 조사도구와 리더십생활기술 조사도구로 구성되어 있다. 청소년 동아리활동 참여관련 조사도구는 동아리수, 동아리 종류, 동아리 가입기간, 동아리 임원여부, 동아리 참여정도, 동아리활동 만족정도, 외부의 동아리활동 지원정도 등 7개로 설정하였다. 청소년 리더십생활기술 조사도구는 최창욱(2001)의 연구에서 개발한 것을 사용하였다. 이 연구에서 나타난 주요 결과 및 함의는 다음과 같다. 첫째, 참여한 동아리수가 많고, 비공식/사이버동아리 참여하며, 가입기간이 길고, 임원 경험이 있으며, 동아리 참여에 적극적이고 동아리활동에 만족하고 있으며, 동아리활동에 대한 지원이 많은 동아리에 참여하는 청소년 집단이 그렇지 않은 청소년 집단에 비하여 리더십생활기술 수준이 높게 나타났다. 둘째, 청소년 동아리활동 참여 관련 변수인 활동 동아리수, 동아리 종류, 동아리 가입기간, 동아리 임원여부, 동아리 참여정도, 동아리활동 만족도, 외부의 동아리활동 지원정도 등 총 7개의 변인군에 의해 종속변수인 리더십생활기술 수준의 총 변량의 11.8%를 설명하는 것으로 나타났다. 투입된 설명변수의 종속변수에 대한 영향력은 열성적으로 참여하고, 외부의 지원이 많은 동아리에 참여하고, 가입기간이 긴 청소년들의 리더십생활기술에 상대적으로 영향력이 큰 것으로 파악되었다. 동아리활동을 통하여 청소년의 리더십생활기술을 향상시키기 위해서는 무엇보다도 청소년들이 열성적으로 참여할 수 있는 여건을 조성하고, 동인을 제공해야 하고, 이를 위한 지원책을 강구할 필요가 있다.

Purpose: We report a case in which a convergent strabismus fixus due to head trauma-induced bilateral abducens nerve palsy was successfully corrected. Methods: A 45-year-old male patient who had bilateral,convergent strabismus fixus and limited eye movement because of bilateral abducens nerve palsy. A year previously, the patient had experienced a skull fracture and right facial nerve palsy caused by a traffic accident. At that time, the forced duction test revealed severe restriction of both eyes. The forced duction test still showed resistance after the right medial rectus muscle was disinserted. We made a conjunctival incision on the lateral canthal area and resected the right lateral rectus muscle. Then we performed lateral canthotomy, and fixed the lateral rectus muscle to the periosteum of the lateral orbital rim. When the left medial rectus muscle was disinserted, there was no resistance on the forced duction test. We then addressed the medial rectus muscle recession, superior and inferior rectus muscle transposition to the lateral rectus. Results: Two years after the procedure, bilateral convergent strabismus fixus did not recur, even though right eyeball movement was impossible. Patient appeared an orthophoria at the primary position, and the cosmetic rersult was satisfactory

나수균,김연일,장세영,이병일,최창욱 순천향대학교 1988 논문집 Vol.11 No.1

The neurovascular island graft is an accepted method of restoring sensation to a localized tactile area on the hand. The procedure has been used to provide sensation to the volar surface of pedicle flaps on the thumb and to replace pulp tissue avulsed from the thumb or index finger. The patient had injured on right thumb by trauma and treated with autogenous bone graft and pedicle flap at local clinic, transferred at out department. We performed neurovascular island graft for defective sensibility of right thumb from the ulnar side of the right ring finger. In follow up for one year, recovery of protective sensation was good but reorientation of sensation was good but reorientation of sensation was poor.

The purpose of any fracture fixation method is two folds; to maintain alignment and to create an optimal millieu for tissue survival and fracture healing. Two major indications for external skeletal fixation are; A) extensively open fractures requiring wound care and closure by other than primary methods, and B) grossly unstable fractures requiring stabilization for soft tissue support and fracture alignment. The advantages of this method are that it involves less metal and less extensive surgical exposure than internal fixation devices, ample wound access, more rigid fixation, early ambulation, and increased patient comfort. In cases of very sever open fractures, this method seems to be the treatment of choice and can reduce the frequency of amputation. Recently, complete long-term follow-up results showed that healing times can be reduced if the period of rigid external fixation is reduced. Clinical success with external fixation remains highly dependent on the degree to which a surgeon can maximize its advantages and minimize its pitfall and complication. The author had analyzed 61 cases of open tibial fractures, which had been treated with various external fixation devices among 78 cases from Jan. 1980 to Dec. 1985 in Soonchunhyang University Hospital and Soonchunhyang Chunan Hospital. Fifteen delayed union were found. There is more advantage if removal of the external fixator, as soon as false motion becomes absent and callus formation is evident in roentgenogram.

In order to observe the changes in number of mast cell in lungs of albino rats against Paragonimus iloktsuenensis infection, rats of three experimental groups were infected with 20 metacercariae of Paragonimus iloktsuenensis, and they were kept for 3 days, 3 weeks and 4 weeks. Right after the each end of the infection period the lung tissues were fixed in 10% neutral formalin and embedded in paraffin. Their sections were stained with Hematoxylin and Eosin for general observation, and toluidine blue for mast cells. All the sections were examined under light microscope and the results obtained were as follows: 1. In the early stages of infection with P. iloktsuenensis there were noticeable changes in lung parenchyma and mast cell numbers in comparing with normal control. 2. After four weeks of infection the invasion of lungflukes into lung parenchyma was noticed. The lesions were represented by thick and fibrosclerotic cavern, granuloma due to eggs, and the increase of peribroncheal lymphatic tissue. A number of mast cell in this infection period were found in these lesions.

The disassembly of modular total hip prosthesis in the postoperative period has been reported with increasing frequency. This involves disassembly of modular acetabular cups, modular head - neck systems and bipolar systems. Disassembly of the components of bipolar endoprosthesis of the Bateman and Christiansen designs have been reported previously. We report on an unusual case of a patient in whom a modular, taper - locked femoral head seperated from the shell ; the seperation occurred during an attempt at closed reduction of a hip that had dislocated posteriorly.

Purpose: Blind individuals who have photoreceptor loss are known to perceive phosphenes with electricalstimulation of their remaining retinal ganglion cells. We proposed that implantable lateral geniculate body (LGB)stimulus electrode arrays could be used to generate phosphene vision. We attempted to refine the basicreference of the electrical evoked potentials (EEPs) elicited by microelectrical stimulations of the optic nerve,optic tract and LGB of a domestic pig, and then compared it to visual evoked potentials (VEPs) elicited byshort-flash stimuli. Methods: For visual function measurement, VEPs in response to short-flash stimuli on the left eye of thedomestic pig were assessed over the visual cortex at position Oz with the reference electrode at Fz. Afteranesthesia, linearly configured platinum wire electrodes were inserted into the optic nerve, optic track andLGB. To determine the optimal stimulus current, EEPs were recorded repeatedly with controlling the pulse andpower. The threshold of current and charge density to elicit EEPs at 0.3 ms pulse duration was about ±10 μA. Results: Our experimental results showed that visual cortex activity can be effectively evoked by stimulationof the optic nerve, optic tract and LGB using penetrating electrodes. The latency of P1 was more shortenedas the electrical stimulation was closer to LGB. The EEPs of two-channel in the visual cortex demonstrateda similar pattern with stimulation of different spots of the stimulating electrodes. We found that the LGBstimulatedEEP pattern was very similar to the simultaneously generated VEP on the control side, althoughimplicit time deferred. Conclusions: EEPs and VEPs derived from visual-system stimulation were compared. The LGB-stimulatedEEP wave demonstrated a similar pattern to the VEP waveform except implicit time, indicating prostheticbasedelectrical stimulation of the LGB could be utilized for the blind to perceive vision of phosphenes.
