  • The synoptic structures and precipitation impact of extratropical cyclones (ETCs) influencing on the three adjacent megacities in East Asia, i.e., Beijing (Beijing ETCs), Seoul (Seoul ETCs) and Tokyo (Tokyo ETCs), are analyzed using ERA-interim reanalysis data from 1979 to 2018. Individual ETC tracks are identified with the automated tracking algorithm applied to 850-hPa relative vorticity field. Among four seasons, ETCs are the most frequent in spring. In this season, Beijing ETCs are mainly generated at the leeside of Altai-Sayan Mountains and primarily develop through interaction between the upper-level trough and lower-level cyclonic circulation. For Seoul ETCs, the leesides of Altai-Sayan Mountains (Seoul-N ETCs) and Tibetan Plateau (Seoul-S ETCs) are main genesis regions and the features of ETCs are different according to the genesis regions. While Seoul-N ETCs mainly develope by the same mechanism of Beijing ETCs, strong diabatic heating due to vapor transport is responsible for the genesis of Seoul-S ETCs. Tokyo ETCs are originated from the leesides of Tibetan Plateau and Kuroshio-Oyashio Extension regions, and strong diabatic heating as well as interaction between upper and lower levels determines the genesis of these ETCs. The precipitation impact resulting from ETCs become strong in the order of Beijing ETCs, Seoul-N ETCs, Seoul-S ETCs, and Tokyo ETCs and accounts for up to 40%, 27%, 52%, and 70% of regional precipitation, respectively.

  • The purpose of this study is to analyze the organic forms, expressions, and characteristics of Alexander McQueen's fashion design and to present various materials for understanding and utilizing this organic design style. The criteria for organic design expressions and characteristics were classified through a literature review, and the organic design characteristics of Alexander McQueen's fashion were then analyzed. The results are as follows: First, the morphological characteristics of nature's forms are used as objects in Alexander McQueen's fashions to represent organic characteristics. Second, abstraction through the application of organic forms means creating an abstract representation of the object being represented. Abstracting organic forms occurs by partially modifying the structural features of the human body to show characteristics or by visualizing these characteristics within the surface of the natural object. Third, continuity through the expression of the formation process of organisms is characteristic of the expression of the gradual growth of organisms; this reinterpretation is based on the concept that the internal elements of natural objects affect their external forms. Fourth, the structure of using natural materials, as well as regional and cultural characteristics, is shown in the designs through use of the physical characteristics of expressions and materials that use natural elements. Fifth, symbolism through subjective thinking implies that the element of nature that an object expresses is the element that appears in nature; this includes created organisms along with environmental factors. These characteristics are best demonstrated in fashion designs that express themselves through creativity.

  • The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion causing massive side-to-side mass effect which leads to compression of the contralateral cerebral peduncle against the free edge of the cerebellar tentorium. Diagnosis is based on "paradoxical" motor deficit ipsilateral to the lesion associated with radiologic evidence of damage to the contralateral cerebral peduncle. To date, there is scarce evidence regarding KWNP associated neuroimaging patterns and motor function prognostic factors. A systematic review was conducted on Medline database from inception to July 2021 looking for English-language articles concerning KWNP, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research yielded 45 articles for a total of 51 patients. The mean age was 40.7 years-old and the male/female sex ratio was 2/1. 63% of the patients (32/51) suffered from head trauma with a majority of acute subdural hematomas (57%, 29/51). 57% (29/51) of the patients were in the coma upon admission and 47% (24/51) presented pupil anomalies. KWNP presented the neuroimaging features of compression ischemic stroke located in the contralateral cerebral peduncle, with edema in the surrounding structures and sometimes compression stroke of the cerebral arteries passing nearby. 45% of the patients (23/51) presented a good motor functional outcome; nevertheless, no predisposing factor was identified. A Glasgow coma scale (GCS) of more than 3 showed a trend (p=0.1065) toward a better motor functional outcome. The KWNP is a regional compression syndrome oftentimes caused by sudden and massive uncal herniation and leading to contralateral cerebral peduncle ischemia. Even though patients suffering from KWNP usually present a good overall recovery, patients with a GCS of 3 may present a worse motor functional outcome. In order to better understand this syndrome, future studies will have to focus on more personalized criteria such as individual variation of tentorial notch width.

  • This study examines the process of the introduction of stupa, which has originated in India, to the Xinjiang Uyghur region and the features of the stupas in the Xinjiang Uyghur region in detail. This study examines the layout of the buildings in temple compounds and the types, structural elements, and construction methods of the stupas in the Xinjiang Uyghur region in particular by looking into the content of the Da Tang Xi Yu Ji and remaining stupas, which provide examples of stupas at the time. This study finds that due to the characteristics of dry deserts, stupas in Xinjiang Uyghur region, where assimilation between Eastern and Western cultures is seen, were mostly made by pressing clay into a mold and had no interior spaces. Also, construction materials and techniques had been developed and improved in a way that enabled stupas to combat the challenging desert conditions. However, the stupas in this region differed significantly from the wooden tower-like stupas discovered in central China(zhongyuan 中原). The shape of the dome of most stupas in Xinjiang Uyghur region was chosen under the influence of the Gandharan style. Some of the stupas in the region have taken the general forms of the wooden stupas and the others have taken many forms, from cylindrical drums to towers. Also, there have been forests of stupas and stupas similar in form to chaityas and stupas of Vajrayana. Such different forms were transformed and modified through regional history and it was related to the peoples and cultures that produced and used stupas. Stupas evolved into distinct forms in Xinjiang Uyghur region in this way.

  • Recently introduced image classification methods using Transformers show remarkable performance improvements over conventional neural network-based methods. In order to effectively consider regional features, research has been actively conducted on how to apply transformers by dividing image areas into multiple window areas, but learning of inter-window relationships is still insufficient. In this paper, to overcome this problem, we propose a transformer structure that can reflect the relationship between windows in learning. The proposed method computes the importance of each window region through compression and a fully connected layer based on self-attention operations for each window region. The calculated importance is scaled to each window area as a learned weight of the relationship between the window areas to re-calibrate the feature value. Experimental results show that the proposed method can effectively improve the performance of existing transformer-based methods.

  • Recently, attention to the pandemic situation represented by COVID-19 emerged problems caused by unexpected shortage of medical personnel. In this paper, we present a method for diagnosing the presence or absence of lesional sign on PA chest X-ray images as computer vision solution to support diagnosis tasks. Method for visual anomaly detection based on feature modeling can be also applied to X-ray images. With extracting feature vectors from PA chest X-ray images and divide to patch unit, region-specific abnormality can be detected. As preliminary experiment, we created simulation data set containing multiple objects and present results of the comparative experiments in this paper. We present method to improve both efficiency and performance of the process through hard masking of patch features to aligned images. By summing up regional specificity and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to previous studies. By aggregating region-specific and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to our last study.

  • As the WTO·DDA continues to stagnate, mega FTAs such as the TPP will likely play the leading role in rule-making of trade for some time to come, creating a 'spaghetti bowl' of trade rules. FTAs, notably high-standard and broad-based regional or mega-FTAs, are the appropriate means to achieve this objective, because they cover many of the policy measures that are needed for the development of global value chains(GVC). The highest quality FTAs are increasingly adding new features like regulatory harmonization that may also foster GVC growth in partner countries. Complementary relationships among markets along value chains, involving both goods and services, also complicate analysis. This is particularly relevant when thinking about policy, since the traditional tendency to think about policies and regulate markets in unconnected silos can lead to unintended and undesirable results. This paper examines the current states of FTAs to determine which are more likely to push this latest wave of globalization further and faster, and explores the plans that are most helpful for GVC growth.

  • Purpose: This study aimed to compare the clinical features of methanol and ethylene glycol poisoning. Methods: This single-center retrospective observational study included patients with toxic alcohol poisoning who visited a regional emergency medical center. Patients with methanol and ethylene glycol poisoning from January 2004 to June 2023 were selected for the study using diagnostic codes. Results: Twenty-two patients with toxic alcohol poisoning visited during the study period, with 11 patients for each category. Compared to methanol poisoning, ethylene glycol poisoning patients were more likely to have consumed alcohol for suicidal purposes (n=4 [36.36%] vs. n=8 [72.73%]) and were more likely to be drowsy (n=0 vs. n=6 [54.55%], p=0.016). The anion gap (25.43±8.35 mmol/L vs. 13.22±6.23 mmol/L, p=0.001) and lactic acid levels (1.785 [1.3-2.785] mmol/L vs. 9.90 [4.20-11.81] mmol/L, p=0.007) were higher in ethylene glycol poisoning patients than in methanol poisoning patients. Among alcohol dehydrogenase blockers, oral ethanol was administered to 10 patients (45.45%) (n=4 [36.36%] vs. n=6 [54.55%]), and intravenous ethanol was administered to six patients (n=4 [36.36%] vs. n=2 [18.18%]). Fomepizole was administered to two patients (9.09%) each, and renal replacement therapy was non-significantly more common in patients with ethylene glycol poisoning (n=8 [72.73%] vs. n=3 [27.27%], p=0.128). Three patients had delays in diagnosis and treatment, and while there were no fatalities, one patient was left with permanent vision damage. Conclusion: Because these are uncommon types of poisoning and the clinical presentation is difficult to recognize early, healthcare providers should be familiar with toxic alcohol types and screen for them to ensure proper diagnosis and treatment.

  • The disaster impact assessment system was introduced in 2005 as a disaster prevention procedure for comprehensive and systematic developmental projects. However, according to the 'Practical Guidelines for Disaster Impact Assessment', Jeju Island's unique hydrogeological features necessitate the calculation of isohyetal-based probabilistic rainfall, which can reflect altitude, when estimating probabilistic rainfall for flood volume determination, rather than using conventional methods. Despite Jeju Island being centered around Hallasan, there are three Automatic Weather Stations (AWS) located at the summit of Hallasan, making weather stations denser than in other cities and provinces. Therefore, it is judged that there would be no difficulty in applying conventional methods, such as utilizing the probabilistic rainfall data from the weather stations or employing the Thiessen method, to estimate flood volumes for small-scale project areas. Accordingly, this study conducts a comparative analysis of the impact of applying general probabilistic rainfall from weather stations and isohyetal-based probabilistic rainfall in site in the context of Jeju Island's disaster impact assessment system.
