본 논문에서는 인간의 표정과 목소리를 기반으로 한 감정 분석기를 제안한다. 제안하는 분석기들은 수많은 인간의 표정 중 뚜렷한 특징을 가진 표정 7가지를 별도의 클래스로 구성하며, DNN 모델을 수정하여 사용하였다. 또한, 음성 데이터는 학습 데이터 증식을 위한 Data Augmentation을 하였으며, 학습 도중 과적합을 방지하기 위해 콜백 함수를 사용하여 가장 최적의 성능에 도달했을 때, Early-stop 되도록 설정했다. 제안하는 표정 감정 분석 모델의 학습 결과는 val loss값이 0.94, val accuracy 값은 0.66이고, 음성 감정 분석모델의 학습 결과는 val loss 결과값이 0.89, val accuracy 값은 0.65로, OpenCV 라이브러리를 사용한 모델 테스트는 안정적인 결과를 도출하였다.

Cholelithiasis and choledocholithiasis are uncommon pediatric diseases, although clinicians have seen them with increasing frequency in children in recent years. Moreover, no case of Epstein-Barr virus (EBV) infection with cholelithiasis and choledocholithiasis has been previously reported in the English literature. We report a pediatric patient with EBV infection, a gall bladder stone, and a common bile duct stone, may have had GB and CBD stones prior to her EBV infection, whom we successfully treated with antibiotics and laparoscopic cholecystectomy for cholecystitis.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder characterized by fever, pancytopenia, hyperferritinemia, and phagocytosis of hematopoietic cells in bone marrow, liver, or lymph nodes. HLH can occur during the course of systemic lupus erythematosus (SLE), but can also be a presenting manifestation. Because development of pancytopenia occurs in less than 10 percent of SLE cases, investigation for HLH is necessary when otherwise unexplained pancytopenia persists despite adequate treatment. We experienced three cases of secondary HLH associated with SLE. Among the three patients, two patients developed HLH during the clinical course of SLE. The other patient who presented with pancytopenia was first diagnosed with HLH, and later with SLE. In her case, HLH turned out to be a presenting manifestation of SLE. We report on three successfully treated cases, and discuss the prevalence, characteristics, treatments, and prognosis of secondary HLH associated with SLE. (J Rheum Dis 2015;22:180-185)

Background: Secondary hemophagocytic lymphohistiocytosis (HLH) can occur during the course of systemic lupus erythematosus (SLE), but also can also be a presenting manifestation. Case1: The 13-year old girl who was diagnosed with SLE a year ago presented with fever. Since she had redness and tenderness on her left fifth fingertip, we assumed that cellulitis was the cause of fever and treated her with antibiotics. Her fever persisted, so we increased her steroid to treat SLE fiare which might have been overlooked. However, pancytopenia, hyperferritinemia and hypertriglyceridemia developed, we biopsied her bone marrow. She was diagnosed with secondary HLH and received steroid pulse therapy. Case2: The 27-year old woman presented with fever and bleeding tendency. Her laboratory results revealed pancytopenia, hyperferritinemia and hypertriglyceridemia. We biopsied her bone marrow and she was diagnosed with HLH. She had pericardial effusion, proteinuria and low serum complement level and was positive for anti-nuclear antibody and anti-double strand DNA antibody. As a result, she was diagnosed with SLE at the same time. We treated her with steroid, etoposide and cyclosporine. Case3: The 30-year old woman who was diagnosed with SLE fifteen years ago presented with fever. We suspected SLE fiare and increased her steroid. Despite treatment, she constantly had fever and her laboratory results showed pancytopenia, hyperferritinemia and hypertriglyceridemia, we gave her steroid pulse therapy and biopsied her bone marrow. She was diagnosed with secondary HLH. All three patients became afebrile and recovered from their pancytopenia after treatment. Conclusion: Since pancytopenia develops in less than 10 percent of SLE cases, the investigation for HLH is necessary when otherwise unexplained pancytopenia persists despite adequate treatment. Hereby we report three successfully treated cases, and discuss the prevalence, characteristics, treatments and prognosis for secondary HLH associated with SLE.
