It has become serious problem in the acute hematogenous osteomyelitis in children that diagnosis and treatment are delayed. 24 cases of acute pyogenic osteomyelitis in children were studied who were admited in the Dept. of Orthopedic Surgery, Chungnam University Hospital for 3. 6 years from Jan. 1976 to jun. 1979. Following results were obtained : 1. Sex ratio was 2.4 : 1. Age distribution showed the gooup between 6 and 10 yrs old was 11 cases (45.8%). 2. Most frequent sites of involvement were distal femur and proximal tibia(45.8%). 3. Duration of disease showed the group between 3 and 7 days was 8 cas cases(33.3%) and 7-14 days was 6(25%). 4. Erythrocyte sedimentation rate was definitely increased in 20 cases (83.3%) and most reliable criteria for stopping antibiotics. 5. The most frequent causative organism was coagulase (+) staphylococcus(70%) and result of negative culture has deeep relation to antibiotics administration before culture. 6. Early diagnosis and early operation seem to be the best method of treatment in acute hematogenous osteomyelitis in children.

Fractures of The Elbow region in children are many problem in treatment and accompanying complication. In the region of the elbow, however, there are aften more indications for aggressive treatment, including operative management. Anthors performed clinical analysis about Fractures of The Elbow region in children, analysed 140 cases during the period of 4 years and 11 months from Jan. 1988 to Nov. 1992, had undergone treatment at the Department of Orthopaedic Surgery, Chungnam University National Hospital. The results obtained are as follows: 1. Of all fractures, Fx Humerus, Supracondylar was 67.2%, most common in The Elbow region in children. 2. In Supracondylar Fractures, extension tyoe was 90.4% and flexion type was 9.6%. According to the Holmberg classification, Group Ⅰ(14.9%), Group Ⅱ (22.3%), Group Ⅲ (18.1%) and Group Ⅳ (44.7%). 3. The supracondylar Fractures were on the left side in 62.4% and male comprised 61.7%. 4. The most common in lateral condyle fracture of the humerus were Milch's type Ⅱ (90.5%) there were Jakob's stage Ⅰ (26.3%), stage Ⅱ (52.6%) and stage Ⅲ (21.1%). 5. The Fractures of the medial humeral epicondyle were most common type, stage Ⅱ and Ⅲ (86.7%).

American Dream and New Management in Alfred P. Sloan’s Adventures of a White-Collar Man

이광진 서울대학교 미국학연구소 2017 미국학 Vol.40 No.2

This paper analyzes Alfred P. Sloan, Jr.’s Adventures of a White-Collar Man published in 1941. It attempts to find the reason that he wrote the book then. Sloan explicitly insists that the prosperous American society was possible thanks to the adventurers in engineering and business. This paper interprets that he intended to remind the readers that the American Dream were still valid and alive. More importantly, this paper points out that more significant aspects of this book is that it shows the rise of new era in business management. Due to the complexity and the size of the companies, Sloan found totally new and effective principles and successfully applied them to General Motors. The new management that he used became a standard ever since. Therefore

외국문학 텍스트를 활용한 교양교육 연구 1: 문제인식·의사소통 수업모형을 중심으로

이광진 중앙대학교 외국학연구소 2018 외국학연구 Vol.- No.44

In the era of preparing for the fourth industrial revolution, problem-solving ability is the most important ability. However, in order to solve the complicated and diverse problems of society quickly, accurately and rationally, we need not only individual capacity but also team activity. Therefore, the ability to search for solutions through collaborative activities with other people is desperately needed. In this study, we propose a new instructional model to improve learners’ problem-solving ability and communication skill. And this model suggests a way to transform and to expand thinking through foreign literary text in a liberal arts curriculum rather than the major courses. It is a teaching method to develop problem-solving ability and creative thinking by using foreign literature text while communicating with others. The emphasis in this model is to identify the nature of the foreign literature text through team communication activities. The process of understanding and the process of problem-solving are performed simultaneously. It enables the learner to enjoy the foreign literature text properly.

다변량 다중비교 결과의 시각화에 관한 연구

이광진 한국자료분석학회 2016 Journal of the Korean Data Analysis Society Vol.18 No.5

In this paper, a visualization method for the results from the multiple comparison in multivariate one-way ANOVA is tried. In the case that the number of groups is large, such a method may be more needed. It is based on a distance matrix between groups. Each element of it is the minus value of the logarithm of the p-value that is obtained from two independent sample ‘modified Hotelling’s T^2-test’ and is calculated by using the bootstrap method. Then these p-values have the feature that are free to the assumptions of equality of covariance matrices and multivariate normality. The graphical representations of it can be made by multidimensional scaling and/or hierarchical clustering. The distance matrix of it can also be used for positioning and/or clustering the groups in the aggregate data. Naturally this method may involve some loss of information. For the explanation and applicability of the suggested method, some graphical results obtained by applying it to an open sample data are presented. 본 연구에서는 먼저 다변량 다중비교 결과의 시각화는 물론 집단자료에 대한 위치화 및 군집화 기법들의 근거가 될 수 있는 집단간 거리를 ‘독립표본 Hotelling의 T^2-검정’에서의 유의확률을 이용하여 정의한다. 물론 유의확률들을 계산할 때 정규성 및 공분산행렬의 동일성이라는 가정에 구애받지 않도록 ‘수정된 Hotelling의 T^2-검정’의 통계량과 부스트랩 기법의 사용을 권한다. 유의확률의 역수에 대한 대수변환을 통해 유의확률들의 행렬로부터 거리행렬을 만든 후 이에 대해 다차원척도법 및 계층적 군집분석법을 적용함으로서 다변량 다중비교 그림 또는 집단들의 포지셔닝맵 및 덴드로그램 등을 얻는 절차를 제안한다. 설명과 활용가능성 확인을 위해 공개용 예제 자료에 적용해 본 결과들을 함께 제시한다.

이광진,박종진 대한무도학회 2019 대한무도학회지 Vol.21 No.4

이 연구에서는 레슬링 선수의 등속성 근력, 근 구조적 특성 및 하지근력 불균형을 비교 분석하는데 그 목적이 있다. 이 연구의 대상은 대한레슬링협회에 등록된 레슬링 선수 11명으로 하였으며, 모든 대상자들은 등속성 근력(60°/sec, 180°/sec) 및 외측광근, 대퇴직근 및 내측광근의 구조적 특성(두께, 깃각, 근속길이)을 측정하였다. 우세측과 비우세측의 등속성 근력과 근 구조적 특성을 비교하기 위해 종속표본 t-검정을 실시였으며, 불균형 비율을 구하는 공식[(우세측-비우세측)/우세측 × 100]을 이용하여 모든 변인의 불균형 비율을 구하였다. 60°/sec의 최대근력(p<.001), 외측광근의 두께(p<.01)와 깃각(p<.05) 및 대퇴직근의 깃각(p<.05)은 우세측이 비우세측에 비해 높은 것으로 나타났으며, 불균형 비율은 60°/sec의 최대근력 12%, 외측광근의 깃각 12.5%, 대퇴직근의 깃각 11.7%로 나타났다. 따라서 이 연구에서 60°/sec의 최대근력에서 우세측과 비우세측의 차이는 외측광근의 두께, 깃각 및 대퇴직근의 깃각의 구조적 특성에 의해 발생될 수 있다는 사실을 확인하였으며, 특히 깃각은 레슬링 선수의 하지근력 불균형을 확인할 수 있는 평가 지표로서 활용될 수 있다고 판단된다. The purpose of this study is to comparative analysis of isokinetic muscular strength, muscle architecture, lower extremity muscle strength in elite wrestlers. The subjects were eleven wrestlers registered with the Korea Wrestling Federation. Isokinetic muscular strength (60°/sec, 180°/sec), vastus lateralis and rectus femoris muscle architecture (thickness, pennation angle, fascicle length) were measured. To compare the isokinetic muscular strength and architecture of the dominant and non-dominant sides, the dependent sample t-test was performed and the formula for calculating all variables imbalance ratio [(dominant-non-dominant) / dominant side × 100] was used. Dominant side was higher than the nom-dominant side at the peak torque of 60°/sec, vastus lateralis muscle thickness and pennation angle and rectus femoris muscle thickness. the proportion of imbalance was 12% of peak torque at 60°/sec, 12.5% of the vastus lateralis muscle pennation angle and 11.7% of the rectus femoris muscle pennation angle. Therefore, in this study, it was confirmed that the difference between the dominant and non-dominant sides of peak torque at 60°/sec could be caused by the architecture of vastus lateralis muscle thickness and pennation and rectus femoris muscle pennation. Especially, it is thought that pennation angle can be used as an evaluation index to identify wrestler’s lower extremity muscle imbalance.

Thirty children with fracture of shaft of the femur were encountered into retrospective analysis to compare the results between conventional (traction with 90-90 followed by hip spica cast) and operative methods (Ender nail intramedullary nailing and external fixation) especially pointing to residual deformity, shortening, hospitalization and sets of radiographs. Our conclusion for this study is that the most femoral shaft fractures in children over 7 years of age can be treated by closed I-M nailing or external fixator with results that are not better than with conventional method in addition to less shortening, deformity, hospitalization and sets of radiographs taking. Other factors such as comminution, site of fracture, head injury, multiple injury in addition to age of child should be considered to select the method of treatment in femoral shaft fracture in children.
