노민영 광주교육대학교 초등국어연구소 2022 초등국어과교육 Vol.29 No.-

본 연구는 쓰기 교육에서 활용하는 동료피드백 활동에서 학습자의 쓰기 수준별 양상의 차이가 있음에 주목하여 동료피드백을 활용한 교수·학습에의 방향성을 살피고자 하는 것에 목적을 가진다. 연구 결과 쓰기 수준 상위 및 하위 학습자 집단에서 서로 다른 양상을 확인할 수 있었다. 상위 학습자는 동료의 글에 구체적이고 명확한 피드백을 제공하였으나 더 나은 수행을 할 수 있음에도 불구하고 인지적인 노력을 더 하지 않고 수행을 멈추는 양상을 보였다. 하위 학습자는 동료로부터 받은 피드백을 수용하면서도 자기점검 과정을 거쳐 피드백 받지 않은 것에 대해서도 고쳐쓰기를 수행하는 모습을 보였으나 쓰기 장르적 지식을 이해하는 것에는 미흡함을 보였다. 이를 통해 학습자 쓰기 수준을 고려한 피드백의 주체의 다양화, 동일한 쓰기 수준으로 이루어진 동질 집단 피드백과의 혼용 운영, 교사 비계 제공의 필요성과 같은 시사점을 얻을 수 있었다.

Contralateral Tension Pneumothorax during One Lung Ventilation by a Univent® Tube

노민영,문성하,김현수 영남대학교 의과대학 2012 Yeungnam University Journal of Medicine Vol.29 No.1

Tension pneumothorax during one-lung ventilation (OLV) is a rare but life-threatening complication. A 79-year-old male patient who was diagnosed with lung cancer underwent Univent® Tube (Fuji Systems Corporation, Tokyo) intubation for left upper lobectomy. Two hours after the initiation of OLV, the patient could not tolerate it. Thus, oneand two-lung ventilation were alternatively applied to continue the operation. After the operation, an emergent chest radiograph was taken, and pneumothorax was found at the right (dependent) lung field.

The Relation between Real Activities based and Accrual-based Earnings Management in U.S. Banking Industry

노민영,정부천 한국회계학회 2018 會計學硏究 Vol.43 No.4

We examine whether bank managers use real activities manipulation (or transaction-based earnings management) and accrual-based earnings management as substitutes in managing earnings based on U.S. banking industry. We find that bank managers trade off these two earnings management methods based on their relative costs and that managers adjust the level of accrual-based earnings management according to the level of real activities manipulation realized. In addition, banks with higher exposure to fair value accounting rely less on accrual-based earnings management using loan loss provisions as the extent of fair value exposure increases the availability of transaction-based earnings management. Finally, the trade-off relation between accrual-based earnings management and real-activities manipulation is more pronounced after the 2008 financial crisis. In sum, we provide evidence that bank characteristics and the level of alternative earnings management are important determinants of earnings management activities in banking industry. We also contribute to the literature on the effects of financial crisis and fair value accounting on earnings management choices. In particular, the role of fair value accounting in banks’ earnings management practices should be of interest to regulators as they consider ways to increase stability in the banking sector

Parkinson's syndrome is a degenerative brain disease that presents characteristic motor symptoms of tremor, rigidity, and gait disturbance. In addition to these motor symptoms, Parkinson's syndrome also presents non-motor symptoms (NMSs) such as sleep disturbance and cognitive decline. NMSs reduce patient's quality of life and psychosocial functioning and cause economic burden on the patient, so appropriate evaluation and treatment are required. Lewy body dementia is one of the several diseases belonging to Parkinson's syndrome. Its symptoms such as cognitive function, memory impairment, and hallucinations occur with Parkinsonism. Although drug therapy is being used with drug treatment to treat non-motor symptoms, it has limitations such as side effects, which stimulated interest in other complementary treatment methods such as oriental medicine treatment, dance, and yoga. The patient in this case complained of tremor in the right upper extremity, muscle hypertension and pain, and persistent vision, memory, and cognitive decline. The patient was diagnosed with probable Lewy body dementia. The patient was hospitalized for 4 months and received acupuncture and herbal medicines. After treatment, the patient's NMS scale scores decreased from 90 to 63, and the Unified Parkinson's Disease Rating Scale scores (summed I, II, and III) decreased from 17 points to 8 points. The Beck Depression Inventory score decreased from 22 points to 13 points. In addition, the patient's subjective evaluation revealed improvement. In this case, a patient diagnosed with probable Lewy body dementia who did not respond to the standard treatment and did not want to take medications showed improvement in not only motor symptoms but also NMSs after integrative Korean medicine treatment.

노민영,한선숙,김태희 대한마취통증의학회 2015 Anesthesia and pain medicine Vol.10 No.1

Background: The goal of this prospective study was to determinethe effect of midazolam pretreatment on the desflurane requirementfor blunting the sympathetic response after surgical incision(minimum alveolar concentration blockade of adrenergic responses,MACBAR) when desflurane is combined with a target-controlledconcentration of remifentanil at 1 ng/ml. Methods: Sixty-five patients aged 30 to 60 years with AmericanSociety of Anesthesiologists physical status of I or II who wereundergoing general anesthesia for thyroidectomy were registeredfor this study. The patients were randomly allocated to receive either30 μg/kg of midazolam (Group M) or isovolemic saline (Group C)intravenously before anesthetic induction. All patients wereanesthetized with propofol, rocuronium, desflurane and remifentanilat a target-controlled effect-site concentration of 3 ng/ml at intubationfollowed by 1 ng/ml throughout the study. Sympathetic responsesto surgical incision were determined 10 minutes after stabilizationof end-tidal desflurane and target-controlled remifentanil concentrations. The predetermined end-tidal desflurane concentrations andMACBAR for each group were determined using an up-and-downsequential allocation technique. Results: The MACBAR of desflurane with 1 ng/ml remifentanilconcentration was 7.1 and 6.8% without and with midazolampretreatment, respectively, using Dixon’s up-and-down method (P= 0.755). Conclusions: Midazolam administered intravenously beforeanesthetic induction does not impact the MACBAR of desflurane withan effect-site concentration of remifentanil 1.0 ng/ml.

환위험이 신용등급에 미치는 영향

노민영,채수준 한국회계학회 2014 회계저널 Vol.23 No.5

본 연구는 기업 환위험의 노출정도와 환위험 관리가 신용평가에 반영되고 있는지를 검증한다. 구체적으로 선행연구(정석우 외 2012)에 근거한 환위험 측정치를 사용하여 기업의 환위험을 경제적 환위험과 회계적 환위험으로 구분하고, 각각의 환위험이 신용평가 결과와 연관되어 있는지를 살펴보고자 한다. 2000년부터 2010년까지 신용평가사로부터 신용등급을 부여받은 3,475개 기업-연도 표본을 대상으로 분석한 결과는 다음과 같다. 첫째, 신용평가기관은 외화자산 및 부채의 비중이 크거나 해외수출비중이 커서 경제적 환위험 노출이 큰 기업일수록 낮은 신용등급을 부여하는 것으로 나타났다. 이는 환위험에 따른 영업현금흐름 및 회계적 이익의 변동성이 그 기업의 미래 상환능력에 부정적인 영향을 미칠 것으로 기대되기 때문이다. 둘째, 사후적으로 환위험을 효과적으로 관리하는 기업의 경우, 즉 회계적 환위험이 작을수록 높은 신용등급을 부여받는 것으로 나타났다. 본 연구의 결과는 환율변동 위험에 노출된 정도가 큰 기업일수록 수익 및 재무구조의 안정성이 감소하므로 낮은 신용등급을 부여받으나 기업이 헤지를 통해 효과적으로 환위험을 관리할수록 환율변동에 따른 자산부채 및 이익의 변동성이 감소하여 높은 신용등급을 부여받는다는 것을 의미한다. 또한, 단기신용등급을 나타내는 기업어음에 대한 신용평가등급을 사용하여 동일한 분석을 수행한 경우에도 일관된 결과를 보여주었다. This paper examines whether firms' foreign currency risk exposure and the effectiveness of foreign currency risk management are associated with credit rating. Using 3,475 firm-year observations from 2000 to 2010, we find that firms receive less favorable credit ratings as firms' economic foreign currency risk, which is measured as 1) the ratio of foreign assets and liabilities and 2) export ratio, increases. In addition, if firms' management of accounting exposure to foreign currency risk has been effective, firms are more likely to receive higher credit ratings. The results suggest that increased volatility of operating cash flow and earnings from foreign currency risk exposure affects negatively firms' future ability to repayment, which results in less favorable credit ratings. However, firms' effective foreign currency risk management from hedge decreases the volatility of firms' future value, resulting in more favorable credit ratings. The results hold when we use credit ratings for commercial paper (CP) which represent relatively short-term credit ratings.

Lumbar epidural block is one of effective methods for treating low back pain with or without radiculopathy. However, neurologic complications can occur after epidural block due to several causes such as direct nerve injury or epidural hematoma. It is important to determine whether the neurologic complication is related to the procedure or is due to the underlying neurologic disease. We report two cases of patients who complained of weakness in their lower extremities after receiving a lumbar epidural block; they were ultimately diagnosed with amyotrophic lateral sclerosis.

국가 온실가스 감축목표(NDC) 상향안 달성을 위한 17개 광역시도별 발전 및 최종에너지 소비 변화 분석

노민영,전승호,김문태,김수덕 한국환경경제학회 2022 자원·환경경제연구 Vol.31 No.4

Korean government updated her Nationally Determined Contribution (NDC) in 2021 and announced the target and various measures for reductions. Among the many issues, final energy demand and renewable energy power mix for 17 provinces to achieve the target are being analyzed using GCAM-Korea. Simulation results show that final energy demand of 2030 is approximated at the similar level to that of 2018. This is being enabled by the conservation of coal with higher electrification especially in industry sector. Higher power demand with lower coal consumption in final energy consumption is shown to be provided by 33.1% of renewable, 24.6% of gas, and 18.0% of nuclear power generation in 2030. Meanwhile, the share of coal-fired power generation is expected to be reduced to 12.8%. Major future power provider becomes Gyeongbuk (Nuclear), Gyeonggi (Gas), Jeonnam (Nuclear, Gas) and Gangwon (PV, Wind), compared to one of current major power provider Chungnam (Coal). This analysis is expected to provide a useful insight toward the national and provincial energy and climate change policy. 2021년, 정부는 국가 온실가스 감축목표(Nationally Determined Contribution, NDC)를 상향 설정하고 에너지 분야의 주요 감축 방안과 감축목표를 제시하였으나, 다양한 쟁점이 논의되고 있다. 그 중 NDC 감축목표를 달성하기 위한 에너지수요와 신재생에너지 발전 비중을 17개 광역시도 통합평가모형 GCAM-Korea로 분석하였다. 그 결과, 2030년 최종소비부분의 에너지수요는 2018년과 비슷한 수준이었다. 이는 석탄 비중의 감소와 전기화가 진행되면서 가능한 것으로 보이며, 특히, 산업부문에서 그 현상이 뚜렷이 나타났다. 최종소비부문에서 증가한 전기수요와 감소한 석탄 발전량(2030년 발전 비중 12.8%)은 신재생(33.1%), 가스(24.6%), 원자력(18.0%)이 부담하는 것으로 나타났다. 이에 따라 미래의 주요 발전지역은 현 주요 발전지역인 충남(주요 발전원, 석탄)에서 경북(원자력), 경기(가스), 전남(원자력, 가스), 강원(태양광, 풍력)으로 바뀌었다. 이와 같은 연구 결과는 국가와 지자체의 에너지 정책 및 온실가스 감축 전략 도출을 위한 기반자료로 활용될 수 있을 것으로 기대한다.

Objectives Facial features can be utilized as an indicator of Korean medical diagnosis. They are often measured by using the diagnostic device for an objective diagnosis. Accordingly, it is necessary to verify the reliability of the features which are obtained from the device for the accurate diagnosis. In this study, we attempt to evaluate the repeatability of facial feature variables using the Sasang Constitutional Analysis Tool(SCAT) for the Sasang Constitutional face diagnosis. Methods Facial pictures of two subjects were taken 24 times respectively for two days according to a standard guideline. In order to evaluate the repeatability, the coefficient of variation was calculated for the facial features extracted from frontal and profile images. Results The coefficient of variation was less than 10% in most of the facial features except the upper lip, trichion, and chins related features. Conclusions It was confirmed that the coefficient of variation was small in most of the features which enables the objective and reliable analysis of face. However, some features showed the low reliability because the location of facial landmarks related to them is ambiguous. In order to solve the problem, a clear basis for the location discussion is required.
