공장 자동화 시스템이 증가됨에 따라 인건비 감소와 생산량 증가, 효율적인 작업 운영, 그리고 고도의 정밀 작업과 인재의 감소 등 여러 가지 이점이 있지만, 자동화 시스템의 문제로 생산 작업이 중단될 경우에 공장의 생산에 미치는 영향 또한 막대하다. 본 논문에서는 공장 자동화 시스템을 효율적으로 관리할 수 있도록 사전에 시스템 장애를 모니터링 할 수 있는 장애 검출 방안에 대하여 제시하고, 이에 따른 효과를 제시하였다. 또한 제시된 방법은 시스템 내 각종 서버의 문제를 검출할 수 있고, 관리자는 모니터링 한 내용을 바탕으로 장애를 조치하는데 있어서 상당한 효과를 볼 수 있었으며, 이것이 생산량 증가로 이어지는 성과를 거둘 수 있다.

Acute pulmonary infarction by tumoral thromboemboli is an extremely rare fatal complication as the first clinical manifestation of hepatocellular carcinoma (HCC) patient with tumoral thrombi in the inferior vena cava. The treatment method has not been established and shown to very poor prognosis despite of trying various modalities such as anticoagulation, radiotherapy and thromboembolectomy. Here, we describe a 74-year-old man who was diagnosed with HCC that presented as pulmonary thromboembolism and subsequent pulmonary infarction as the first manifestation.

Purpose: Up to 10% of the mortality rate of asthmatics within a year from the near-fatal attacks has been reported. We previously reported that not a few patients with acute severe asthma died after discharge from the hospital. This study investigated whether our efforts to improve clinical outcomes of patients after recovery from severe asthma exacerbation did work or not. Methods: Follow-up data from asthmatic patients who had been hospitalized due to severe exacerbation between 2007 and 2014 (present) were compared with that the previous one (1998.2006) (previous). Results: Sex, age, near-fatal asthma, and mortality (9.8% vs. 9.6%) were not significantly different between the previous (n=225) and present (n=397) studies. However, rehospitalization rate was significantly lower in the present study (29.3% vs. 52.4%, P=0.000). The patients in the present study used inhaled steroid more frequently (78.5% vs. 68.0%, P=0.006), had better asthma knowledge (P=0.000), and higher proportion of regular hospital visitors to total subjects (75.6% vs. 64.9%, P=0.004) than did the previous patients. The regular hospital visitors (n=300) showed a significantly lower mortality (3.3% vs. 28.9%, P=0.000), better knowledge (P=0.000) and higher inhaled steroid use (85.8% vs. 54.1%, P=0.000) than did the other group (n=97) in the present study. Conclusion: Clinical outcomes after recovery from severe asthma exacerbation in the present study were better than the previous one. Our efforts to educate patients might contribute to these better results. (Allergy Asthma Respir Dis 2016:4:340-345)
