오동규 대한공업교육학회 2012 대한공업교육학회지 Vol.37 No.1

This study was to analysis perception about Teaching & Learning Support System of the school of Rural Areas in Korea. In order to accomplish the study purpose, the study conducted a research through Web Survey method and examined their recognition. Major findings of this study were as follows:First, Student was satisfied with TLSS of the school of Rural Areas in Korea. Students would like to ‘using e-learning with Electronic board and Tablet PC’ among program contents. But the system’ utilization was low. However, 90% of the students wanted that teacher usually using the FASTEL. Second, Teacher satisfaction was lower compared to the students is relatively. Teachers prefer ‘various after school program’ to ‘using e-learning with Electronic board and Tablet PC’. However, learning effective of using FASTEL system was a 73.8% of teachers are effective is aware and had. Third, 35% Students recognized that are using the pastel system, frequently, On the other hand, the teachers are 60% and to recognize that there was. The reason doesn't the system to good use is slow wireless. Still, e-learning classroom infrastructure for satisfaction was high. Fourth, Teachers recognized students and the pastel system interaction than other e-learning system high. FASTEL System used in the most uncomfortable things on e-learning classroom Wireless Internet phenomena and lost content lacking, in order, I was told. Therefore, there is an urgent need to improve to include Wireless Internet speed improvements and various content added support, easy-to-use instructional tools Add support order selected. 이 연구는 전원학교 교수학습지원시스템의 현황을 알아보기 위하여 전원학교 교수학습지원시스템에 대한 교사와 학생들의 인식을 조사하는 데 있었다. 이 연구의 모집단은 전원학교 110개교의 교사와 학생들로 학교별로 5명의 교사와 20명의 학생들을 대상으로 웹 서베이를 실시하였다. 자료 수집은 2011년 12월 2일부터 2011년 12월 8일까지 실시하였으며, 초, 중학생 1280명과 교사 188명이 참여하였다. 이 연구의 결과는 다음과 같았다. 첫째, 전원학교 교수학습지원시스템에 대한 학생들의 만족도는 높았다. 전원학교의 프로그램 중에서 ‘전자칠판과 태블릿PC를 사용하는 이러닝’을 가장 선호하였다. 그러나 학교에서 태블릿PC와 FASTEL 시스템의 활용이 ‘매일’이나 ‘주3-4회’가 40%이하로 활용도가 매우 낮았다. 그럼에도 불구하고 선생님들이 자주 FASTEL을 활용하는 것을 90%이상의 학생들이 원하고 있었다. 따라서 학생들은 FASTEL시스템을 선생님들이 적극적으로 활용하는 것을 바라고 있으며 무선으로 사용하는 전원학교 이러닝 교실 수업에 흥미 있고 효과적이며 편리하다고 보고 있었다. 둘째, 전원학교 이러닝 교실과 FASTEL 시스템에 대한 교사들의 만족도는 학생들에 비하면 상대적으로 낮았다. 전원학교 프로그램 선호도에서 교사들은 ‘다양한 방과후 학교’를 ‘태블릿PC를 사용하는 첨단 이러닝’보다 더 선호하고 있었다. 그러나 FASTEL 시스템이 학생들의 학습에 효과적인가에 대해서는 73.8%의 교사들이 효과적인 것을 인식하고 있었다. 셋째, FASTEL 시스템의 활용도에 있어서 학생들은 ‘매일’이나 ‘주3-4회’가 35%내외 인 반면에서 교사들은 60%내외로 인식하고 있었다. 따라서 교사들의 적극적인 활용을 높여 학생들의 인식과의 격차를 줄여야 할 것이다. 태블릿PC를 잘 사용하지 않는 이유로 무선 인터넷 속도가 느리고 태블릿PC 사용이 불편함을 선택하였다. 그럼에도 이러닝교실의 인프라에 대한 만족도는 높았다. 넷째, 교사들은 FASTEL 시스템이 타 이러닝시스템보다 학생과 상호작용을 할 수 있다는 특징에 대하여 인식(41.7%)하고 있으나 무선인터넷 기반(23%)과 편리한 수업도구(16%)도 긍정적으로 보고 있다. FASTEL 시스템 사용에 가장 불편한 것으로 이러닝 교실의 무선 인터넷 끊김 현상과 콘텐츠 부족 순으로 들었다. 따라서 시급히 개선해야 할 사항으로 무선인터넷 속도의 개선과 다양한 콘텐츠 추가 지원, 편리한 수업도구 추가지원 순으로 선택하였다.

오동규,도경현,이상민,한승봉,김동순 대한결핵 및 호흡기학회 2012 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.114 No.0

목적: 폐기종을 동반한 특발성폐섬유증(CPFE)환자는 노력성폐활량(FVC)의 감소는 적지만 폐확산능(DLco)의 감소가 심하고 폐고혈압의 유병률이 높아 FVC 변화를 주지표로 하는 임상연구에서 이들을 제외해야 한다는 주장이 있다. 하지만 아직까지 이에 대한 근거가 없어 본 연구를 시행하였다. 방법: 서울아산병원에서 IPF로 진단된 환자 중 고해상도흉부전산화단층촬영(HRCT)의 분석이 가능하고 진단 후 12개월의 폐기능검사 결과가 있는 212명을 대상으로 진단시 HRCT 상 폐섬유증및 폐기종의 정도, 진단 후 12개월의 FVC 감소와 생존율의 관계를 조사하였다. 결과: CPFE군은 77명(36.3%)으로 순수 IPF군에 비해 남성과 흡연자가 많았고, 진단 시 두군 사이에 폐섬유화 지수는 차이가 없었으나(7.8 vs. 8.4,p=0.168), FVC 86.3% vs. 74.5% (p<0.001), DLco 65.0% vs. 69.3% (p=0.136)였고, 폐고혈압의 빈도는 23.4% vs 6.1% (p=0.004)였다. 두 군간에 생존률의 차이는 없었고 폐섬유화지수는 중요한 생존예측인자였다. 양군에서 진단 후 12개월의 FVC 감소 정도는 사망의 유의한 예측인자였으나(CPFE군: HR 1.038, p=0.030; 순수IPF군: HR 1.061, p<0.001), FVC 감소 정도는 CPFE군에서 순수 IPF군보다 작았다(120 ml: 4.65% vs 20ml: 0.27%, p=0.008). 결론: CPFE군에서는 진단 후 12개월의 FVC 감소가 적고 사망예측에 미치는 영향도 감소하므로 임상연구에서는 이들을 제외하는 것이 타당할 것으로 사료된다.

오동규,최창민,김우성,이재철 대한결핵 및 호흡기학회 2017 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.124 No.0

Purpose: Osimertinib is a 3rd generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) active for both sensitizing mutations and T790M of EGFR. Although it has proven its efficacy and safety in clinical trials, there are limited data in real world practice, especially in Korea. Methods: We reviewed medical records of T790M+ lung cancer patients treated with Osimertinib after acquiring resistance to 1st or 2nd generation EGFR-TKI between February 2016 and June 2017. In addition to the efficacy and safety, the moleculo- pathologic data of rebiopsy samples after the development of resistance to Osimertinib were analyzed. Results: Of 22 patients, median age was 59.5 and 10 (45.5%) were male. The median duration of follow-up was 11.9 months (IQR 4.7-15.8). Fourteen (63.6%; 95% CI 43.0-80.3) achieved an objective response and the disease was controlled in 21 (95.5%; 95% CI 78.2-99.2). Median progression-free survival was 7.3 months (95% CI 3.6-11.0). The adverse effects were minimal except a case of pneumonitis. Among 14 patients who experienced disease progression during Osimertinib, rebiopsy was performed in 8. T790M disappeared in 4 (50%) and one of them showed a wild-type conversion. Transformation to small cell carcinoma was observed in 2 (25.0%) and the C797S mutation was detected in 1 (12.5%). Conclusion: Osimertinib showed favorable efficacy and safety profiles comparable to those of clinical trials in real world practice in Korea. The rebiopsy samples after the acquisition of Osimertinib-resistance is needed to guide the following treatment strategy.

Anti-inflammatory Effects of Aroma Oil Complex on DNCB-Induced Allergic Contact Dermatitis in Dogs

오동규,오태호 한국임상수의학회 2014 한국임상수의학회지 Vol.31 No.3

Allergic contact dermatitis (ACD) is an inflammatory skin disease and regarded as a prototype of T-cellmediated delayed-type hypersensitivity reactions. Aroma Oil Complex (AOC) is composed of lavender true oil,chamomile roman oil and tea tree oil. This study was performed to assess the effects of AOC in a canine modelof ACD. ACD was induced on the back of dogs induced by sensitization and repeated application by 2,4-dinitro-1-chlorobenzene (DNCB). Topical treatment of AOC was applied once a day for 8 days and skin biophysical parametersincluding transepidermal water loss (TEWL), skin hydration, skin thickness and erythema index, were measured everytwo days during experimental periods. Histopathology and immunohistochemistry were performed to evaluate the antiinflammatoryeffect. In skin biophysical parameters, TEWL, skin hydration, skin thickness and erythema index weresignificantly increased, with a maximum increase appeared on day 2 (p < 0.05). After the completion of AOC treatment,skin biophysical parameters were significantly reached those of baseline in a time-dependent manner (p < 0.05). Inhistopathology, marked increases of epidermal thicknesses were induced after DNCB challenge with numerousinflammatory cell infiltrations and edematous changes, decreases of connective tissue occupied regions in dermis. Inaddition, marked increases of cytokine - tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ)-immunoreactivitiesin the dermis and of apoptotic markers - caspase-3 and PARP-immunoreactivities in the epidermis were observed inDNCB control as compared with intact control, respectively (p < 0.01). The decrease of infiltrated inflammatory cellsand related decreases of pro-inflammatory cytokine immunoreactivities were observed in AOC treated skin (p < 0.01). Based on these findings, AOC may have anti-inflammatory and alleviatory effects in the allergic contact dermatitis.

Lung Regeneration Therapy for Chronic Obstructive Pulmonary Disease

오동규,김유선,오연목 대한결핵및호흡기학회 2017 Tuberculosis and Respiratory Diseases Vol.80 No.1

Chronic obstructive pulmonary disease (COPD) is a critical condition with high morbidity and mortality. Although several medications are available, there are no definite treatments. However, recent advances in the understanding of stem and progenitor cells in the lung, and molecular changes during re-alveolization after pneumonectomy, have made it possible to envisage the regeneration of damaged lungs. With this background, numerous studies of stem cells and various stimulatory molecules have been undertaken, to try and regenerate destroyed lungs in animal models of COPD. Both the cell and drug therapies show promising results. However, in contrast to the successes in laboratories, no clinical trials have exhibited satisfactory efficacy, although they were generally safe and tolerable. In this article, we review the previous experimental and clinical trials, and summarize the recent advances in lung regeneration therapy for COPD. Furthermore, we discuss the current limitations and future perspectives of this emerging field.

오동규,나원준,박유랑,허진원 대한결핵 및 호흡기학회 2017 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.124 No.-

Purpose: Age is an important prognostic factor of the patients treated in the medical intensive care unit (MICU). We performed the study to assess the age-specific trends in the MICU utilization. Methods: Data were obtained from the patients admitted to an MICU of a tertiary hospital between July 2006 and June 2015. Patients were grouped by age and the age-specific trends were analyzed in demographics, comorbidities, disease severities, and MICU admission and mortality rates. Results: Of 8,018 patients, the mean age was 61.1 years and male were 5,094 (63.5%). The most common comorbidity was cancer (42.0%). Interestingly, in the age group < 50 years, the proportion of hematologic malignancy was more common than in the other age group (18.6% vs. 11.0%, p < 0.001). The disease severity assessed by sequential organ failure assessment (SOFA) score was higher in the age group < 50 years than in ≥ 70 years (8.1 [95% CI 7.8 - 8.3] vs. 7.2 [95% CI 7.0 - 7.3], p < 0.001). The MICU admission rates were consistently increased with age, but the MICU mortality rates showed bimodal distribution peaked in the age group < 50 and ≥ 80 years. Contrary to the decreasing temporal trend in the MICU mortality rates in the age group ≥ 80 years (R² = 0.35, p = 0.09), those in < 40 years showed increasing temporal trend (R² = 0.66, p = 0.005). Conclusion: Although the MICU admission rate was much lower in younger age group, the MICU mortality rate in this group was comparable to that in older age group. These might be related to the comorbidities and disease severities.

오동규,고승영,강승모 대한교통학회 2013 대한교통학회지 Vol.31 No.2

The purpose of this research is to optimize the line planning of the intercity passenger railway. In this study, the line planning problem has been formulated into a mixed integer programming by minimizing both user costs (passenger’s total travel time) and operator costs (operation, maintenance and vehicle costs) with multiple train types. As a solution algorithm, the branch-and-bound method is used to solve this problem. The change of travel demand, train speed and the number of schedules have been tested through sensitivity analysis. The optimal stop-schedules and frequency as well as system split with respect to each train type have been found in the case study of Kyoung-bu railway line in Korea. The model and results of this research are useful to make a decision for railway operation strategy, to analyze the efficiency of new railway systems and to evaluate the social costs of users and operators. 본 연구는 지역간 여객 철도의 노선계획을 최적화하는 방법에 관한 연구이다. 본 연구의 노선계획 모형은 다양한 차종이 운용되는 철도노선에서 이용자비용(이용자의 총 통행시간)과 운영자비용(열차 운행비용, 유지·보수비용, 차량구입비용)의 합을 최소화하고자 하는 혼합정수계획 수리모형으로 구축되었고, 모형의 해법으로 분기한정법이 사용되었다. 수요의 변화, 열차 속도의 변화, 정차스케줄 수의 변화 등에 대한 민감도 분석 결과도 제시하였고, 국내 경부선의 사례연구를 통하여 각 열차차종의 차종별 수요 분할 뿐만 아니라 최적 정차스케줄과 운행빈도를 동시에 산출할 수 있음을 보여주었다. 본 연구의 모형과 결과는 열차 운영 전략을 수립하거나 새로운 철도 시스템의 효율성을 분석하거나 이용자·운영자의 사회적 비용을 산정하는 경우 등에 적용될 수 있다.
