  • As a part of research to elucidate the pathogenesis of so called Soft Tunic Syndrome(STS), that caused mass mortalities in the cultured sea squirts, Halocynthia roretzi, the epidemiological and pathological analysis were done to both clinically normal and diseased groups of the farms of Tongyoung and Geoje coastal areas in southeast sea from February to July, 2008. In the histological finding of the tunic, most of individuals showed tunic softness syndromes that included the disarrangement and destruction of tunic fiber with the simultaneous presence of flagellates-like cells, recently suspected as main agents of tunic softness syndromes. Simultaneously, the intensive degenerative changes of the skeletal muscle of diseased sea squirts were recognized. The changes were characterized with the hyalinization and condensation of muscle fibril and hemocytic infiltration in the muscle fibers. Those were thought to be a kind of typical Zenker's necrosis as in the skeletal muscle of higher vertebrates. Besides of the diseased sea squirts, Zenker's necrosis of skeletal muscles were seen in the normal ones. Epidemiological inquiry for diseased groups revealed that the higher incidences of tunic softness syndrome were recorded in the fast growing groups and in the sites presuming the organic pollution. And Higher malondialadehyde(MDA) and glutathione peroxidase(GPx) activity were detected in the groups showing STS. Those results suggested that Zenker's necrosis of body muscles was a kind of"nutritional myopathy" by oxidative stress. Conclusively, it was considered that Zenker's necrosis of body muscles gives an important clue for elucidating pathogenesis of STS of cultured squirts. And it seems that the necrosis were caused by the oxidative stress to body muscle during abnormal rapid growth of sea squirts.

  • Objectives: To review and analyze clinical and preclinical evidence of effectiveness, safety, and underlying mechanisms of yokukansan (YKS), a herbal medicine, in alleviating aggression. Methods: Classical records on YKS were searched in the Korean Traditional Medicine Knowledge Database (KTMKD). By searching five electronic databases, prospective clinical studies and preclinical studies of YKS for alleviating aggression/agitation published up to March 30, 2021 were included. Results: Only two classical records on YKS were found from the KTMKD. A total of 11 clinical studies and 15 preclinical studies were found from the five electronic databases. Among 11 clinical studies, seven enrolled patients with dementia and four enrolled patients with other neuropsychiatric disorders. Most clinical studies reported significant improvement in one or more outcomes related to aggression in the YKS group after treatment. Among 15 preclinical studies, all studies except two reported a significant decrease in aggression/agitation-related behavior of YKS or yokukansankachimpihange. Suggested underlying mechanisms of YKS or yokukansankachimpihange for aggression/agitation in these studies included regulation of serotonin receptor, amelioration of abnormal glucocorticoid level related to the hypothalamic-pituitary-adrenal axis, regulation of orexin secretion, amelioration of degeneration in brain cells including glia cells, and suppression of excessive glutamatergic or dopaminergic activity. Conclusions: There were some clinical and preclinical evidence supporting the effectiveness and safety of YKS for alleviating aggression. Given that aggression is the most frequent and destructive symptoms of behavioral and psychological symptoms of dementia, applicability of YKS as a herbal medicine should be further investigated in future high-quality research.

  • Errors in the semiconductor process are generated by a change in the state of the equipment, and errors usually arise when the state of the equipment changes or when parts that make up the equipment have flaws. In this investigation, we anticipated that aging of the mass flow controller in the plasma enhanced chemical vapor deposition SiO2 thin film deposition method caused a minute flow rate shift. In seven cases, fourier transformation infrared film quality analysis of the deposited thin film was used to characterize normal and pathological processes. The plasma condition was monitored using optical emission spectrometry data as the flow rate changed during the procedure. Preprocessing was used to apply the collected OES data to the artificial immune system algorithm, which was then used to process diagnosis. Through comparisons between datasets, the learning algorithm compared classification accuracy and improved the method. It has been confirmed that data characterized as a normal process and abnormal processes with differing flow rates may be discriminated by themselves using the artificial immune system data mining method.

  • 본 논문은 시계열 데이터에 존재하는 이상값을 정상값으로 변환하는 새로운 데이터 보정기법을 제안한다. 최근 IT기술의 발전으로 센서를 통해 방대한 시계열 데이터가 수집되고 있다. 하지만 센서의 고장, 비정상적 환경으로 인해, 대부분의 시계열 데이터는 다수의 이상값을 포함할 수 있다. 이상값이 포함된 원천 데이터를 그대로 사용하여 예측모델을 구축하는 경우, 고신뢰도의 예측 서비스가 실현되기 어렵다. 이에 본 논문은 LSTM-GAN 모델을 활용하여 원천 시계열 데이터에 존재하는 이상값을 탐지하고, DTW(Dynamic Time Warping) 및 GAN 기법을 결합하여 분할된 윈도우 단위로 이상값을 정상값으로 보정하는 기법을 제안한다. 기본 아이디어는 탐지된 이상값이 포함된 윈도우에 인접한 정상 분포 데이터의 통계정보를 DTW에 적용하여 연쇄적으로 GAN 모델을 구축하여 정상적 시계열 데이터를 생성하는 것이다. 오픈 NAB 데이터를 활용한 실험을 통해, 우리는 제안 기법이 기존 2개의 보정기법보다 성능이 우수함을 보인다.

  • Background: To evaluate the efficacy and safety of Phellinus linteus (PL) extract for the treatment of knee osteoarthritis (KOA) a pilot clinical study was performed. Methods: There were 24 patients with KOA who enrolled in this double-blind, randomized, controlled, clinical trial. There were 3 groups: PL 1,000 mg/day (PL 1,000), PL 1,500 mg/day (PL 1,500), and dextrin 3,000 mg/day (placebo). Patients took capsules twice a day, 3 capsules at a time, over 8 weeks. Patients were monitored prior to treatment (Visit 1: Week 0), and followed up every 4 weeks (Visit 2: Week 4 and Visit 3: Week 8) where outcome measurements were taken. The primary outcome measure was the score from the Korean version of the Western Ontario and McMasters Universities from baseline to Week 8. The secondary outcomes were measurements from the visual analog scale, quality of life scale, erythrocyte sedimentation, and c-reactive protein. Adverse events were recorded at every visit. Results: The Korean version of the Western Ontario and McMasters Universities score showed the greatest improvement in symptoms of KOA in the PL 1,500 group compared with the placebo group. The erythrocyte sedimentation tended to decrease in the PL 1,500 group compared with the placebo group (which was within the normal range). The visual analog scale score decreased in all groups, with no significant differences between groups. No adverse events related to PL were reported. There were no abnormal hematological or physical findings. Conclusion: This pilot clinical trial was the first step to assess the efficacy and safety of PL used in the treatment of patients with KOA.

  • As an important research direction of the application of computer science in the medical field, the automatic generation technology of radiology report has attracted wide attention in the academic community. Because the proportion of normal regions in radiology images is much larger than that of abnormal regions, words describing diseases are often masked by other words, resulting in significant feature loss during the calculation process, which affects the quality of generated reports. In addition, the huge difference between visual features and semantic features causes traditional multi-modal fusion method to fail to generate long narrative structures consisting of multiple sentences, which are required for medical reports. To address these challenges, we propose a multi-feature optimization Transformer (MFOT) for generating radiology reports. In detail, a multi-dimensional mapping attention (MDMA) module is designed to encode the visual grid features from different dimensions to reduce the loss of primary features in the encoding process; a feature pre-fusion (FP) module is constructed to enhance the interaction ability between multi-modal features, so as to generate a reasonably structured radiology report; a detail enhanced attention (DEA) module is proposed to enhance the extraction and utilization of key features and reduce the loss of key features. In conclusion, we evaluate the performance of our proposed model against prevailing mainstream models by utilizing widely-recognized radiology report datasets, namely IU X-Ray and MIMIC-CXR. The experimental outcomes demonstrate that our model achieves SOTA performance on both datasets, compared with the base model, the average improvement of six key indicators is 19.9% and 18.0% respectively. These findings substantiate the efficacy of our model in the domain of automated radiology report generation.
