적색경계밴드(red-edge band)가 식물의 생물리적 특성과 밀접한 관계를 가지고 있다고 알려지고 있으며, 이에 따라 최근 적색경계밴드를 포함한 위성영상센서가 증가하고 있다. 본 연구는 향후 농림업중형위성에 적색경계밴드 탑재를 계획하고 있는 점을 감안하여, 적색경계밴드와 관련된 연구 현황과 활용 가치를 분석하고자 한다. 수관울폐도가 높은 우리나라 산림의 엽면적지수(Leaf Area Index, LAI) 추정에 있어서 적색경계밴드의 효과를 분석하였고, 더 나아가 LAI 추정을 위한 최적의 파장폭과 파장영역을 도출하고자 하였다. LAI가 5 이상인 갈참나무와 리기다소나무를 대상으로 4월부터 10월까지 시계열 분광반사 측정자료를 이용하여 LAI와의 상관관계를 분석하였다. 분광반사측정자료에서 5개의 파장폭(10 nm, 20 nm, 30 nm, 40 nm, 50 nm)과 71개의 중심파장(680 nm부터 750 nm까지 1 nm 간격)을 달리하여 모두 355개의 적색경계밴드를 모의 생성했다. 적색경계밴드를 기반으로 하는 두 개의 분광지수 NDRE(normalized difference red-edge index)와 CIRE(chlorophyll index red-edge)를 산출하여 LAI와 상관관계를 분석하였다. 적색경계밴드 기반의 분광지수인 NDRE 및 CIRE는 수관울폐도가 높은 갈참나무와 리기다소나무의 LAI와 높은 상관관계를 얻을 수 있었다. 이는 수관울폐도가 높은 국내 산림에서 일반적으로 사용되는 NDVI가 LAI와의 상관관계가 낮게 나타났던 한계를 해결할 수 있는 가능성을 보여주었다. 10 nm부터 50 nm까지 적색경계밴드의 파장폭 효과는 산림의 LAI와 관계에서 큰 차이를 보이지 않았다. LAI와 최대 상관관계를 보이는 적색경계밴드의 중심파장은 갈참나무에서는 720 nm 부근, 그리고 리기다소나무에서는 710 nm 주변으로 나타났다. 우리나라 농작물 및 산림의 식생정보 획득과 모니터링을 위한 최적의 적색경계밴드의 파장폭과 파장영역을 결정하기 위해서는 다른 생물리적인자(엽록소, 질소, 수분함량, 생체량 등)와의 관계도 충분히 고려하여야 한다.

Obstructive sleep apnea syndrome(OSAS) in childhood is unique and different n-om that in adulthood in several aspects, including pathophysiology, clinical features, diagnostic criteria, complications, management, and prognosis. Characteristic features of childhood OSAS in comparison with the adult form are the variety of severe complications such as developmental delay, more prominent behavioral and cognitive impairments, vivid cardiovascular symptoms, and increased death risk, warranting a special attention to the possible diagnosis of OSAS in children who snore. However, the childhood OSAS is often neglected and unrecognized. We, therefore, report a case of very severe OSAS in a 5-year-old boy who was sucessfully treated with continuous positive airway pressure(CPAP) treatment. Interestingly, the patient was comor-bid with the attention deficit hyperactivity disorder. Prior to the initial visit to us, adenotonsillectomy had been done at the age of 4 with no significant improvement of apneic symptoms and heavy snoring. On the initial diagnostic procedures, marked degree of snoring was audible even in the daytime wake state and the patient was observed to be very hyperactive. Increased pulmonary vascularity with borderline cardiomegaly was noted on chest X-ray. The baseline polysomnography revealed that the patient was very sleep-apneic and snored very heavily, with the respiratory disturbance index(RDI) of 46.9 per hour of sleep, the mean SaO2 of 78.8%, and the lowest SaO2 of 40.0%(the lowest detectable oxygen level by the applied oxymeter). The second night polysomnography was done for CPAP titration and the optimal pressure turned out to be $8.0\;cmH_2O$. The applied CPAP treatment was well tolerated by the patient and was found to be very effective in alleviating heavy snoring and severe repetitive sleep apneas. After 18 months of the CPAP treatment, the patient was followed up with nocturnal polysomnography(baseline and CPAP nights) and clinical examination. Sleep apneas were still present without CPAP on the baseline night. However, the severity of OSAS was significantly decreased(RDI of 15.7, mean SaO2 of 96.2%, and the lowest SaO2 of 83.0%), compared to the initial polysomnographic findings before initiation of long-term CPAP treatment. Wechsler intelligence tests done before and after the CPAP treatment were compared with each other and surprising improvement of intelligence(total 9 points, performance 16 points) was noted. Clinically he was found to be markedly improved in his attention deficit hyperactive behavior after CPAP treatment, but with minimal change of TOVA(test of variables of attention) scores except conversion of reaction time score into normal range. On the chest X-ray taken after 18 months of CPAP application, the initial cardiopulmonary abnormalities were not found at all. We found that the CPAP treatment in a young child is very effective, safe, and well-tolerated and also improves the co-morbid attention deficit hyperactive symptoms. Overall, the growth and development of the child has been facilitated with the long-term use of CPAP. Cardiovascular complications induced by OSAS have been also normalized with CPAP treatment. We suggest that early diagnosis and active treatment intervention of OSAS in children are crucial in preventing and ameliorating possible serious complications caused by repetitive sleep apneas and consequent hypoxic damage during sleep.

IDC(International Data Corporation) 사(社)의 최근 보고서에 따르면, 2025년에는 2016년에 생성된 데이터의 10배에 달하는 163제타바이트의 데이터가 생성될 것이고 그 주체의 비중은 소비자에서 기업으로 이동하고 있다고 한다. 이러한 소위 '빅데이터의 물결'은 도래하고 있고 그 파장은 산업 전반적으로 영향을 미칠 것이다. 따라서, 방대한 데이터를 효과적으로 관리하는 것은 기업의 관점에서 그 어느 때보다 더 중요하다. 하지만, IT 투자에 대한 효과를 측정한 선행 연구는 다수 존재함에도 불구하고 빅데이터 투자 효과를 측정한 선행 연구는 거의 전무한 실정이다. 따라서, 해당 투자 효과를 정량적으로 분석한다면 기업의 의사 결정을 도울 수 있을 것이다. 본 연구는 효율적 시장 가설을 이론적 바탕으로 둔 사건연구방법론(Event Study Methodology)을 적용하여, 기업의 빅데이터 투자가 시장 투자자들의 반응에 미치는 영향을 측정하였다. 또한, 보다 심층적으로 이 효과를 분석하기 위해서 5가지 하위 변수를 설정했고 그 내용은 기업 크기 구분, 산업 구분(Finance와 ICT), 투자 구축 완료 구분, 벤더 유무 구분이다. 분석 결과, 91개 기업은 빅데이터 투자 공시 이후 시장 가치가 평균 0.92% 상승한다는 사실을 확인하였다. 특히 Finance 기업, non-ICT 기업, 시가 총액이 작은 기업, 빅데이터 전문 벤더 기업을 통해 투자한 기업, 그리고 빅데이터 시스템이 구축 완료됐다는 공시에 해당하는 기업의 시장 가치가 두드러지게 상승한다는 사실을 알 수 있었다. 본 연구는 빅데이터 투자 효과를 측정한 선행 연구가 거의 전무하다는 점에서 학문적인 의의를 지니고, 빅데이터 투자를 고려 중인 기업 의사 결정자들에게 실질적인 참고 자료가 될 수 있다는 점에서 실무적인 시사점을 갖는다.
