The aim of this study is to actualize an in-situ measurement system of greenhouse gases using a UAV. This paper presents vertical profiles of CO₂ concentration as a measurement result with operation and long-term maintenance for a periodic flight tests. For this study, a new joint part with a single structure for improving strength of the sensor mount is developed. Moreover, routine maintenance to replace a router and periodic regulation of the analyzer is provided. After updating flight altitude permission over 150 m, we conducted flight tests up to 500 m. We compare individual linear correction and liner regression applied for vertical profiles of CO₂ concentration. We address that correction using linear regression has advantage to reduce burden for in-situ measurement.

What is already known, Tachycardia is seen in almost all cases with febrile status epilepticus caused by an underlying fever, infection, dehydration or the seizure itself. What is new in the current study, Atrial tachycardia should be considered in patients with febrile status epilepticus if the tachycardia is resistant to anticonvulsive treatment.

하구 간석 퇴적 유기물의 기원과 계절적 변동 특성을 해명하는 것을 목적으로, 나나키타강 하구 갯벌의 세립토 함유율(<63 ${\mu}m$), Chl.a, TOC, C/N비 및 탄소 질소 안정동위원소 비(${\delta}^{13}C$, ${\delta}^{15}N$)를 측정했다. 그 결과, 모래질 갯벌에서는 해양성 기원 유기물과 부착 조류의 영향이 큰 것으로 밝혀졌다. 반면, 진흙질 갯벌에서는 육지 기원 유기물의 영향이 컸다. 게다가 퇴적물중의 유기물량과 유기물의 기원은 계절에 따라 변동 하는 것이 분명하고, 그 요인으로서는, 모래질 갯벌에서는 부착 조류와 고조(高潮) 및 월파(越波)에 의한 퇴적이 주요인이었으며, 진흙질 갯벌에서는 육상에서의 유기물의 유출에 의한 퇴적이 특징적이었다. The purpose of this study is to clarify the origin of organic matters on sediment and the characteristics of seasonal variation at an estuarine tidal flat. Silt-clay content (<63 ${\mu}m$), chlorophyll a, TOC, C/N ratio and the stable isotope ratio of carbon and nitrogen were measured at tidal flat around the estuary of the Nanakita River. As a result, organic matters originating from marine organic matter and bethic microalgae greatly contributed to sedimentation of organic matters at Stn.A, sandy tidal flat, though terrigenous organic matters did at Stn.C, muddy tidal flat. Furthermore, it was revealed that the volume and origin of organic matters in the sediments depended on seasonal variation, and the factors were different from the Stns, i.e. bentic microalgae and event for Stn.A, and the eventual sedimentation of organic matters originating from terrestrial plants, respectively.

Ulcerative colitis (UC) is 1 of the 2 major phenotypes of chronic inflammatory bowel disease (IBD), which afflicts millions of individuals throughout the world with debilitating symptoms that impair function and quality of life. Further, IBD often affects women during childbearing age. Indeed, UC activity frequently increases during pregnancy, and the medications used to induce remission may adversely affect the health of the mother and the unborn child. We report successful induction of a remission in a UC case who experienced a flare-up in the first trimester of pregnancy. Upon relapse, she was treated with steroids and adsorptive granulomonocytapheresis (GMA) with the Adacolumn plus tacrolimus. This combination therapy induced a stable remission that was maintained during her entire pregnancy. She gave birth to a healthy child at 36 weeks of pregnancy with no maternal or fetal complications. Our experience indicates that GMA, as a non-drug therapeutic intervention with a favorable safety profile, plus tacrolimus might be a relevant treatment option for patients with active IBD during pregnancy. A future study of a large cohort of pregnant patients should strengthen our findings.

Clinical case studies and reporting are important to the discovery of new disorders and the advancement of medical sciences. Both clinicians and basic scientists play equally important roles leading to treatment discoveries for both cures and symptoms. In the field of movement disorders, exceptional observation of patients from clinicians is imperative, not just for phenomenology but also for the variable occurrences of these disorders, along with other signs and symptoms, throughout the day and the disease course. The Movement Disorders in Asia Task Force (TF) was formed to help enhance and promote collaboration and research on movement disorders within the region. As a start, the TF has reviewed the original studies of the movement disorders that were preliminarily described in the region. These include nine disorders that were first described in Asia: Segawa disease, PARK-Parkin, X-linked dystonia-parkinsonism, dentatorubral-pallidoluysian atrophy, Woodhouse-Sakati syndrome, benign adult familial myoclonic epilepsy, Kufor-Rakeb disease, tremulous dystonia associated with mutation of the calmodulin-binding transcription activator 2 gene, and paroxysmal kinesigenic dyskinesia. We hope that the information provided will honor the original researchers and help us learn and understand how earlier neurologists and basic scientists together discovered new disorders and made advances in the field, which impact us all to this day.
