Corticai Dysplasia(CD) is increasingly recognized as a cause of intractable epilepsy since it can be easily diagnosed with high resolution magnetic resonance imaging(MRI). We analyzed 24 consecutive cases with cortical dysplasia who underwent resective surgery at our institute between September. 1992 and December. 1995. MRI was demonstrated to be a decisive tool to identify CD in 16 cases(66.7%). However, the remaining 8 cases(93.9%) were confirmed to have CD based on histological examination. Location of the lesion included temporal(n=9), central(n=5), multilobar(n=5), and frontal(n=5). Intracranial EEG recording was performed to delineate the epileptogenic zons in 16 cases : subdural grid(10 cases) and depth electrode(6 cases). Resection was performed in temporal(n=9), frontal(n=7), central(n=5). parietal(n=1), and muitilobar(n=1). Complete resection was possible in 15(62.5%) and partial resection in 9(37.5%). Histological examination revealed dyslamination of cortical layers only(n=9), additional dysplastic neurons(n=7), and additional balloon cells(n=8). Surgical outcome was graded as seizure free(n=14 : 58.3%), rare seizures(n=3 : 12.5%). <50% reduction of seizure frequency(n=2 : 8%), and no change(n=5 : 20.8%) after mean follow-up of 12.7 months. The most influencing factor on the surgical outcome was the degree of completeness of resection(p<0.05). However. detectability of CD on MRI, severity of histological findings, age of seizure onset, and duration of seizure were not significantly related with the surgical outcome High suspicion is required to detect the CD among the patients with intractable epilepsy and surgical strategies should be well-planned to improve the surgical outcome in the patients with CD.

Oh Hyoung keun J-INSTITUTE 2018 Kinesiology Vol.3 No.1

The aims of this research are: to identify the ethical issues confronting Korean sport organizations, to find factors influencing the decision making to deal with the ethical issues, and, finally, to suggest development plans for managerial ethics in Korean sport organizations. In particular, the research addresses the following questions: what kind of ethical issues confronting Korean sport organizations? What are the factors influencing decision making to deal with the ethical issues? What are the development plans for managerial ethics in Kore-an sport organizations? Semi-structured interviews were conducted with participants working for Korean sport organizations(N=8). Results revealed that Korean sport organizations have been faced with various ethical is-sues, consisting of two main themes: athlete and coach, and organization. While former was related to man-agement and supervision of athlete and coaches, and latter was pertaining to organization’s internal issues. Regarding the factors influencing decision making to deal with the ethical issues, organization’s regulations and obeying boss were identified. In additions, as the tool of ethics management and organizational policy, ethics training programmes and the code of ethics were not applicable and not practical. Finally, improvement of administrative system and eradication of factionalism were suggested for the development plans for mana-gerial ethics in Korean sport organizations.

Hyoung-Keun Oh,Suk Kyu Choo,Jung-Jae Kim,Mark Lee 대한정형외과학회 2016 Clinics in Orthopedic Surgery Vol.8 No.3

Background: The Stoppa (intrapelvic) approach has been introduced for the treatment of pelvic-acetabular fractures; it allows easy exposure of the pelvic brim, where the bone quality is optimal for screw fixation. The purpose of our study was to investigate the surgical outcomes of unstable pelvic ring injuries treated using the Stoppa approach for stable anterior ring fixation. Methods: We analyzed 22 cases of unstable pelvic ring injury treated with plate fixation of the anterior ring with the Stoppa approach. We excluded cases of nondisplaced rami fracture, simple symphyseal diastasis, and parasymphyseal fractures, which can be easily treated with other techniques. The average age of the study patients was 41 years (range, 23 to 61 years). There were 10 males and 12 females. According to the Young and Burgess classification, there were 12 lateral compression, 4 anteroposterior compression, and 6 vertical shear fracture patterns. The fracture location on the anterior ring was near the iliopectineal eminence in all cases and exposure of the pelvic brim was required for plate fixation. All patients were placed in the supine position. For anterior plate fixation, all screws were applied to the anterior ramus distally and directed above the hip joint proximally. Radiologic outcomes were assessed by union time and quality of reduction by Matta method. The Merle d’Aubigne-Postel score was used to evaluate the functional results. Results: The average radiologic follow-up period was 16 months (range, 10 to 51 months). All fractures united at an average of 3.5 months (range, 3 to 5 months). According to the Matta method, the quality of reduction was classified as follows: 16 anatomical (73%) and 6 nearly anatomical (27%) reductions. There were no cases of screw or implant loosening before bone healing. The functional results were classified as 7 excellent (32%), 12 good (55%), and 3 fair (13%) by the Merle d’Aubigne-Postel score. There were no wound complications, neurovascular injuries, or other complications related to the surgical approach. Conclusions: Stable anterior ring fixation placed via the Stoppa approach can result in excellent reduction and stable screw fixation with a low complication rate

Oh Hyoung keun,Choi Seong kon J-INSTITUTE 2018 Kinesiology Vol.3 No.2

In the present day, the significance of sports has been emphasized as an effective mediator for the interna-tional development cooperation such as by being used for economic and social development of developing coun-tries. The United Nations has designated 2005 as a year for sports and athletics and has also adopted a resolution such that sports are an important means of promoting health, education, development and peace, while stress-ing such a positive role for economic development and social development. In this vein, advanced contributors such as Australia and Canada are participating in the international development cooperation utilizing sports, while international sports organizations including the International Olympic Committee (IOC) as well as sports organizations such as organizations for each event are participating in international development and carrying out activities through sports. As such, even as the significance of sports is stressed for the international develop-ment, related studies are conducted such as the international development and cooperation through sports and sports ODA, yet the studies conducted with sports as an effective tool of the international development cooper-ation intended for strategic plan and system development have been minimal. Accordingly, in this study, the concept and significance of international development cooperation through sports are examined, and recent trends and cases of international development cooperation through sports are analyzed to present strategic al-ternatives for related projects. Strategic implementation plans for international development cooperation through sports include, first, the establishment of global governance among the related organizations, second, the participation of companies to secure stable financial resources, and, third, the utilization of sports stars to help publicize related programs, respectively.

오형근 ( Hyoung Keun Oh ) 대한골절학회 2018 대한골절학회지 Vol.31 No.4

평균 수명의 연장에 의한 골다공증성 골절 환자의 증가는 치료하는 정형외과 의사뿐만 아니라 사회 경제적으로도 부담이 되고 있다. 고령층에서 발생하는 골절의 치료는 젊은 환자의 골절 치료에 비하여 수술 전 고려 사항도 복잡하고, 수술 후 적절한 전신 상태 관리와 더불어 이차적인 골절을 예방해야 하므로 보다 체계적인 접근이 필요하다. 이 장에서는 골다공증성 골절 후 이차적인 골절을 예방하기 위한 약물 치료와 낙상 예방을 위한 전략에 대하여 기술하고자 한다. The prevention and treatment of fragility fractures is evolving continuously. Adequate fracture care should involve treating the fracture itself as well as the underlying bone disease. Although effective treatments of osteoporosis are available, a large proportion of patients with fragility fractures are not prescribed anti-osteoporotic medications after their injury. Recent advances in diagnostic tools and medications allow for a more effective and comprehensive treatment of fragility fractures.

감염성 불유합의 치료 전략

오형근 ( Hyoung-keun Oh ) 대한골절학회 2017 대한골절학회지 Vol.30 No.1

감염성 불유합의 치료를 위해서는 임상적 증상 및 병력을 포함한 철저한 수술 전 조사가 필수적이며 감염의 범위, 내고정물의 안정성, 균주의 독성, 연부 조직의 상태 등에 따라 철저한 수술 전략을 세우고 각 단계의 수술에 대한 구체적인 목표를 설정하여야 한다. 감염의 근치를 위해서는 불안정한 내고정물을 포함한 감염된 골 및 연부 조직에 대한 철저한 변연 절제술이 매우 중요하며 적절한 연부 조직의 피복이 향후 재건술과 감염의 조절에 도움이 된다. 골 결손 범위 및 크기에 따라 자가골 이식술, 골이동술, 혈관 부착 비골 이식술, induced membrane technique 등을 선택할 수 있으며, 골의 안정적인 고정을 위한 적절한 외고정 및 내고정 방법을 선택하여야 한다. The management of infected nonunion is based on a detailed evaluation of patients, the involved bone and soft tissues, stability of fixation, and type of bacterial pathogens. Preoperative surgical planning and strategies for each step is mandatory for the successful treatment of infected nonunion. The radical debridement of infected tissues, including the unstable implant, is one of the most important procedures. Adequate soft tissue coverage should be considered for the appropriate management of infection; a reconstructive procedure and stable skeletal stabilization by internal or external fixation is also necessary later. A restoration of bone defects and bony union can be accomplished with bone grafting, distraction osteogenesis, vascularized fibular grafting, and induced membrane technique.
