Human placenta contains various kinds of nutritional elements essential for embryonic development. Currently, human placenta extracts are widely overused in Korea to improve certain health conditions (postmenopausal syndrome, liver function, and cosmetic purposes) without scientific evidence that they actually work. The use of placenta extracts should be restricted, due to a lack of systematic research on the therapeutic effectiveness and adverse results from these treatments. While the common adverse effects that have been reported are fever, rash, itching, nausea, vomiting, breast pain, and rare cases of anaphylactic shock, there have been no reports of pulmonary complications such as hypersensitivity pneumonitis. Recently, we experienced a patient with hypersensitivity pneumonitis following a placenta extract injection. To our knowledge, this is the first case of hypersensitivity pneumonitis associated with placenta extract use.

도시형 및 중고속 자기부상열차 부상·안내 제어시스템 성능개선에 관한 연구내용으로 현재 영종도에 시험운행중인 부상제어 시스템이 단일 제어기로 전력회로부 이중화 설계 및 제작이 되어 있지 않다. 그러므로 차량 운행시 전력회로부인 주회로의 고장으로 부상실패에 대한 차량의 안정성과 신뢰성을 향상시킬 필요성이 있다. 또한 추진장치의 추진력 변동에 따른 수직력 변동을 고려하여 전자석 부상제어가 가능하도록 개발되어야 한다.

Background: Chronic obstructive pulmonary disease (COPD) is a major cause of death and disability worldwide and one of the most prevalent diseases in Korea. We examined trends and risk factors of health care utilization for COPD in Korea. Methods: We retrospectively analyzed the database of Patient Surveys from 1990 through 2008, which were nationwide surveys of health services utilization through outpatient department (OPD) visits and hospitalization. Physician-diagnosed COPD patients whose ages were 45 years and older were included. Results: OPD visits and hospitalization of COPD patients between 1990 and 2008 were estimated to be 68,552 and 17,774 persons, respectively. Trends in OPD visits and hospitalization for COPD significantly increased from 1990 through 2008 (p=0.019, p=0.001, respectively). The increment rate for OPD visits was 2.0 fold over those years; for hospitalization it was 3.3 fold. Risk factors for OPD visits for COPD were male gender (odd ration [OR], 1.41; 95% confidence interval [CI], 1.39∼1.43), those aged 65 years and older (OR, 1.50; 95% CI, 1.47∼1.53), residential area other than a metropolis (OR, 1.08; 95% CI, 1.07∼1.010) and access to a physician`s office (OR, 1.17; 95% CI, 1.14∼1.21). Risk factors for hospitalization were male gender (OR, 2.15; 95% CI, 2.07∼2.23), those aged 65 year and older (OR, 2.86; 95% CI, 2.72∼3.00), residential area other than a metropolis (OR, 1.98; 95% CI, 1.90∼2.07) and access to a hospital (OR, 2.88; 95% CI, 2.59∼3.22) (p<0.001, both). Conclusion: Health care utilization for COPD subjects increased from 1990 to 2008. Risk factors for the utilization were male gender, older age, and residential area other than a metropolis.

N/A From July 1982 to June 1984, clinical observations were made at the Daegu Fatima Hospital on 157 patients with upper gastrointestinal bleeding confirmed by gastrofiberscopy, and the following results were obtained. 1) Of 157 cases of upper gastrointestinal bleeding, esophageal varices was presentented in 28.7% gastric ulcer in 24.2%duodenal ulcer in 19.1%, gastritis in 16.6%, Mallory-Weiss syndrome in 4.5%, stomach cancer in 3.8% and unknown origin in 3.2%. The ratio of males to females in the group of 157 patients was 4.6: 1. Mean age was 48.8+-14.2 whole. Mean age in duodenal ulcer and Mallory-weiss syndrome were significantly lower than that of other disease group(p<0. 01). 2) Active bleeding, that is, oozing or pumping blood, was observed in 53 out of 157(33.8% Active bleeding was most frequently observed with Mallory-Weiss syndrome and esophageal varices. 3) Among the 157 patients who were endoscoped, within 24 hours 51.0% Of patients were endoscoped; within 48 hours 70.7%; and within 7 hours 84.1% The admission-to-endoscopy interval appeared to be correlated with bleeding activity. The frequency of finding an active bleeding lesions was observed to decrease gradually as this interval increased. 4) Mean hemoglobin level on admission was in 8. 5 gm/dl that was belonged to moderate bleeding group by Palumbos criteria. 5) In patients with an actively bleeding lesion at endoscopy there was a statistically significant increase administration of more than 5 pints of blood(52.8%) and surgical intervention(34.0%), when compared to the outcome in patients with only a clot or no blood observed on lesions at endoscopy(more than 5 pints transfused 27.9% and surgery 12.5% (p<0.01, and p<0.005). 6) Eighty-two percents of patients were improved with conservative treatment, whereas gg pJ of patients required surgical intervention. 77.4% of the operated cases were improved. 7) The mortality rate during the hospitalization was in 3.8%, and causes of death were due to hepatic encephalopathy, renal failure, and blood loss.

기존 IoE 환경에서 수집데이터는 특정 서비스를 위한 도메인 지식과 연계되어 서비스를 제공한다. 하지만 수집되는 데이터의 유형이 다양하고, 정적인 지식베이스가 상황에 따라 동적으로 변화하는 IoE 환경에서는 기존의 지식베이스 시스템을 통하여 원활한 서비스를 제공할 수 없었다. 따라서, 본 논문에서는 IoE 환경에서 발생하는 대용량/실시간성 데이터를 시맨틱으로 처리하여 공통 도메인 지식베이스와 연계하고 기존의 지식베이스 추론 방법과 기계학습 기반 지식 임베딩 기법을 통하여 지식 증강을 유기적으로 진행하는 빅시맨틱 시스템을 제시한다. 제시한 시스템은 IoE 환경의 멀티모달(정형, 비정형) 데이터를 수집하고 반자동적으로 시맨틱 변환을 수행하여 도메인 지식베이스에 저장하고, 시맨틱 추론을 통해 지식베이스를 증강 시키며 증강된 지식베이스를 포함한 전체 지식베이스를 정형 및 반정형 사용자 쿼리를 통해 지식정보를 사용자에게 제공한다. 또한, 기계학습 기반 지식임베딩 기법을 통해 학습·예측을 함으로써, 기존의 지식베이스를 증강하는 기능을 수행한다. 본 논문에서 제시한 시스템은 공장내의 에너지 정보를 수집하여 공정 및 설비 상태 및 운영정보를 바탕으로 실시간 제어를 통한 에너지 절감 시스템인 공장 에너지 관리 시스템의 기반 기술로 구현될 예정이다.
