본 연구는 전력수요의 냉방 및 난방 수요를 측정하고 분석한다. 이를 위해 냉난방기온 효과를 추정하고 이를 Chang et al. (2014)의 전력수요함수 모형에 적용하여 전력수요를 기본 수요, 냉방수요 그리고 난방수요로 분해하였다. 1999년 1월부터 2016년 12월의 한국의 일반용과 주택용 전력수요를 분석한 결과, 난방수요의 증가율이 기본수요와 냉방수요의 증가율을 월등히 상회하였으며 특히 일반용에서 난방수요 증가가 두드러졌다. 평년기온으로 통제한 기온 보정된 난방수요는 실현된 난방수요보다 상대적으로 ‘더’ 증가하였고, 냉방수요는 반대로 기온 보정된 수요가 실현된 수요에 비해서 ‘덜’ 증가하였다. 본 논문은 전력수요 내의 냉방 및 난방 수요를 측정할 뿐 아니라 경제주체들의 전력수요 변화 패턴을 확인했다는 점에 의의가 있으며, 추정 결과들은 향후 전력수요예측과 에너지수요관리 정책 수립에 도움을 줄 수 있을 것으로 기대된다. This paper measures and analyzes cooling and heating demand in Korean electricity demand using time-varying temperature response functions and cooling and heating temperature effects. We fit the model to Korean data for residential and commercial sector over 1999:01~2016:12 and the estimation results show that the growth rate of heating demand is much higher than that of base and cooling demand, and especially the growth rate of heating demand in commercial sector is much higher. And we define the temperature-normalized demand conditioning that monthly temperatures are assumed as average monthly temperatures. The growth rate of heating demand in the estimated temperature-normalized demand is higher than that in the real demand. Our results are expected to be a base data for Winter Demand Management and short-term electricity demand forecasting.
증례 : 감염 ; 간경화 환자에서 Non-O1 Vibrio cholerae에 의한 고름근육염 1예

본 증례는 간경화 환자에서 non-O1 V. cholerae에 의한 고름근육염이 발생한 국내 첫 예이다. 이러한 기저 질환이 있는 환자에서 고름근육염의 원인균으로 non-O1 V. cholerae도 고려하여야 한다. A 63-year-old man with underlying liver cirrhosis was admitted with painful swelling of the right thigh. We identified a non-O1 Vibrio cholerae strain in blood cultures and multiple pyomyositis in the lower limbs. Non-O1 V. cholerae strains have caused several well-studied food-borne outbreaks of gastroenteritis and have been responsible for sporadic cases of otitis media, skin and soft tissue infection, and bacteremia. Skin and soft tissue infection due to non-O1 V. cholerae is rare and is commonly associated with the presence of chronic underlying disease, such as liver cirrhosis, diabetes mellitus, an immunocompromised state, or a hematological malignancy. We report the first case of pyomyositis caused by non-O1 V. cholerae in Korea. Physicians should consider non-O1 V. cholerae strains as a pathogen that can cause pyomyositis.

Acute eosinophilic pneumonia (AEP) is characterized by idiopathic acute febrile illness, diffuse pulmonary infiltration, severe hypoxemia, and pulmonary eosinophilia. We report a case of AEP associated with intramuscular administration of progesterone as luteal phase support after in vitro fertilization. A 33-year-old woman presented to our emergency room with tachypnea and hypoxemia, complaining of fever and cough for 4 days, and dyspnea for 2 days. The symptoms began 9 days after the first injection of progesterone. Chest radiograph showed bilateral infiltrates, located predominantly in the periphery of the lungs, with blunting of the costophrenic angle. Symptoms and chest radiograph dramatically improved after corticosteroid therapy and shifting the progesterone from an intramuscular form of administration to a vaginal form of administration.
