Acquisition System Based on Multisensors for Preserving Traditional Korean Painting.

Rapid industrialization has significantly influenced people's lifestyles in the recent decades, and the influence of traditional culture is diminishing. Recently, several studies attempted to simultaneously utilize various sensors to record delicate and sophisticated performances of intangible cultural heritage (ICH). Although painting is one of the most common ICH of human history, few research studies have recorded traditional painting work. In this paper, we aim to lay the groundwork for reviving Korean painting, even if there would be no painters to produce these traditional Korean paintings in the future. We propose a novel multisensor-based acquisition system that records traditional Korean painting work while minimizing interference in the work. The proposed system captures real-time data originating from the painter, brushes, pigments, and canvas, which are the essential components of the painting work. We utilized the proposed system to capture the painting work by two experts, and we visualize the captured data. We showed the various results of statistical analysis, and also discussed the usability.

USP39-Mediated Non-Proteolytic Control of ETS2 Suppresses Nuclear Localization and Activity.

ETS2 is a member of the ETS family of transcription factors and has been implicated in the regulation of cell proliferation, differentiation, apoptosis, and tumorigenesis. The aberrant activation of ETS2 is associated with various human cancers, highlighting its importance as a therapeutic target. Understanding the regulatory mechanisms and interacting partners of ETS2 is crucial for elucidating its precise role in cellular processes and developing novel strategies to modulate its activity. In this study, we conducted binding assays using a human deubiquitinase (DUB) library and identified USP39 as a novel ETS2-binding DUB. USP39 interacts with ETS2 through their respective amino-terminal regions, and the zinc finger and PNT domains are not required for this binding. USP39 deubiquitinates ETS2 without affecting its protein stability. Interestingly, however, USP39 significantly suppresses the transcriptional activity of ETS2. Furthermore, we demonstrated that USP39 leads to a reduction in the nuclear localization of ETS2. Our findings provide valuable insights into the intricate regulatory mechanisms governing ETS2 function. Understanding the interplay between USP39 and ETS2 may have implications for therapeutic interventions targeting ETS2-related diseases, including cancer, where the dysregulation of ETS2 is frequently observed.

Linear programming method for computing the gamut of object color solid.

Recently there has been great interest in establishing the color gamut of solid colors or the optimum colors. The optimum colors are widely used for quantifying the quality of light sources and evaluating reproduction devices. An enumeration method was developed by Martinez-Verdu et al. [J. Opt. Soc. Am. A 24, 1501 (2007)] for finding optimum colors. However, it was found that the method is too time-costly. In this paper, a linear programming approach is proposed. The proposed method is simple and faster and has the advantage of keeping the characteristics of the true boundary. Comparison of the present method with the method of Martinez-Verdu et al. is also given.

The causes of difficult tracheal intubation and preoperative assessments in different age groups.

BACKGROUND: We studied the differences in airway assessment factors among old, middle, and young age groups, and evaluated the frequency and causes of difficult intubation among these groups. METHODS: Patients were divided into young (< 40 yr, n = 75 ), middle (40-59 yr, n = 83), and old (≥ 60 yr, n = 89) group. Airway assessment factors such as head and neck movement, thyromental distance, interincisor gap, dentition, Mallampati score, and Arné score were assessed. After muscle relaxation, cervical joint rigidity and Cormack-Lehane (C-L) grade were assessed. The differences in airway assessment factors between difficult (C-L grade 3, 4) and easy (C-L grade 1, 2) intubation were then examined. Logistic regression analysis was also carried out to identify the extent to which airway assessment factors reflected difficult intubation. RESULTS: As aging, head and neck movement, thyromental distance, and interincisor gap decreased, the grade of dentition, Mallampati score, cervical joint rigidity and the ratio of Arné score > 11 increased. In the old and middle group, the incidence of difficult intubation was increased compared with the young group. Dentition in the young group, Mallampati score and interinsisor gap in the middle group and Mallampati score, cervical joint rigidity in the old group respectively predicted difficult intubation. CONCLUSIONS: Compared to young individuals, middle-aged or elderly adults are likely to experience more difficulty in endotracheal intubation and its predictive factors could vary by age group.

Different roles of glycine-rich RNA-binding protein7 in plant defense against Pectobacterium carotovorum, Botrytis cinerea, and tobacco mosaic viruses.

Glycine-rich RNA-binding protein7 (AtGRP7) has previously been demonstrated to confer plant defense against Pseudomonas syringae DC3000. Here, we show that AtGRP7 can play different roles in plant defense against diverse pathogens. AtGRP7 enhances resistance against a necrotrophic bacterium Pectobacterium carotovorum SCC1 or a biotrophic virus tobacco mosaic virus. By contrast, AtGRP7 plays a negative role in defense against a necrotrophic fungus Botrytis cinerea. These results provide evidence that AtGRP7 is a potent regulator in plant defense response to diverse pathogens, and suggest that the regulation of RNA metabolism by RNA-binding proteins is important for plant innate immunity.

Conversion phenomenon during the induction period of general anesthesia -A case report-.

Conversion disorder is characterized as psychological symptoms such as somatization and emotional distress, but there is no abnormal electrical signal in the brain. We report a patient who appeared conversion disorder during the induction period of general anesthesia. A 45-year-old woman was planned for arthroscopic knee meniscectomy. In the operating room, she appeared stable, but she said extremely nervous in this situation. Before propofol injection for induction of anesthesia, we injected 1% lidocaine 50 mg iv for pain relief. Immediately after injection, she showed general seizure-like activity and then tonic-rigid muscle tone, dyspnea with periodic breathing without cyanosis, and clouding of consciousness. The operation was delayed, and she was examined by neurosurgeon and psychiatrist. She was diagnosed as suffering with conversion disorder and she was without brain abnormalities on the magnetic resonance imaging. Her condition improved after anti-depressant medication and supportive psychotherapy. She underwent uneventful knee surgery 40 days later.
