In acute pulmonary embolism (PE), circulatory failure and systemic hypotension are important clinically for predicting poor prognosis. While pulmonary artery (PA) clot loads can be an indicator of the severity of current episode of PE or treatment effectiveness, they may not be used directly as an indicator of right ventricular (RV) failure or patient death. In other words, pulmonary vascular resistance or patient prognosis may not be determined only with mechanical obstruction of PAs and their branches by intravascular clot loads on computed tomography pulmonary angiography (CTPA), but determined also with vasoactive amines, reflex PA vasoconstriction, and systemic arterial hypoxemia occurring during acute PE. Large RV diameter with RV/left ventricle (LV) ratio > 1.0 and/or the presence of occlusive clot and pulmonary infarction on initial CTPA, and clinically determined high baseline PA pressure and RV dysfunction are independent predictors of oncoming chronic thromboembolic pulmonary hypertension (CTEPH). In this pictorial review, authors aimed to demonstrate clinical and serial CTPA features in patients with acute massive and submassive PE and to disclose acute CTPA and clinical features that are related to the prediction of oncoming CTEPH.

The purpose of this paper is to explain that the phrasal construction determines the meaning of Korean idiom phrase with two examples, mom_sal and kkoch_tun, within HPSG framework, following the spirit of concept of Construction Grammar. To do so, the paper introduces two English idiom studies of Riehemann et al.(1997) and Cho(1999) and Korean idiom explanation of Suh(1996) as the previous study. A hierarchy for Korean idiom is suggested on the basis of Cho(1999) and two criteria like semantically decomposable idiom phrase and semantically non-decomposable idiom phrase. < Hanlyo University >

The Korean Society of Heart Failure (KSHF) Guidelines provide evidence-based recommendations based on Korean and international data to guide adequate diagnosis and management of heart failure (HF). Since introduction of 2017 edition of the guidelines, management of advanced HF has considerably improved, especially with advances in mechanical circulatory support and devices. The current guidelines addressed these improvements. In addition, we have included recently updated evidence-based recommendations regarding acute HF in these guidelines. In summary, Part IV of the KSHF Guidelines covers the appropriate diagnosis and optimized management of advanced and acute HF.

In this paper, a simplified Cubature Kalman Filter (SCKF) is proposed to reduce the computation load of CKF, which is then used as a filter for transfer alignment of shipboard INS. CKF is an approximate Bayesian filter that can be applied to non-linear systems. When an initial estimation error is large, convergence characteristic of the CKF is more stable than that of the Extended Kalman Filter (EKF), and the reliability of the filter operation is more ensured than that of the Unscented Kalman Filter (UKF). However, when a system degree is large, the computation amount of CKF is also increased significantly, becoming a burden on real-time implementation in embedded systems. A simplified CKF is proposed to address this problem. This filter is applied to shipboard inertial navigation system (INS) transfer alignment. In the filter design for transfer alignment, measurement type and measurement update rate should be determined first, and if an application target is a ship, lever-arm problem, flexure of the hull, and asynchronous time problem between Master Inertial Navigation System (MINS) and Slave Inertial Navigation System (SINS) should be taken into consideration. In this paper, a transfer alignment filter based on SCKF is designed by considering these problems, and its performance is validated based on simulations.

This study focused on two athletic groups, Incheon Athletic Association and Incheon Sports Council, which played their roles in Incheon before Korea was liberated from Japanese rule. The study result is as follows. Purpose: This study will show the establishment, activity and historical meaning of Incheon Athletic Association and Incheon Sports Council that worked in Incheon before the liberation. Method: It used newspapers, magazines, local papers in Incheon, governmental materials and books that dealt with Incheon Athletic Association and Incheon Sports Council under Japanese rule. Result: First, Incheon Athletic Association had led the athletics of Incheon in early 1920s. With the activities the association was established at Inchoen Public Hall on December 18, 1925. Incheon Athletic Association had held “Incheon Athletic Day” and athletic competitions of baseball games and tennis games from 1925. It was a Japanese association. The president of the association was the mayor of Incheon city. Incheon Police Agency used “Mudeokgwan”, a martial art training center, as its training center. It indicates that the local government has controlled the athletics with strong power. Incheon Athletic Association became weak with the fall of Japanese imperialism. Seconds, Incheon Sports Council was established on 8pm, January 11, 1936 at Sansujeong public hall. They needed a control institute for Korean sports that had improved rapidly. Incheon Sports Council handled Korean wrestling, soccer, basketball, skating and archery. It also tried to introduce and promote new sports such as rugby and car racing. But Incheon Sports Council was oppressed and closed by Incheon Mayor(永井府尹). It was merged with Incheon Athletic Association. Conclusion: Incheon Athletic Association was a Japanese athletic group. But it contributed to the development of Incheon’s modern athletics expanding the base of Incheon’s athletics before the liberation. Incheon Sports Council was the first Korean athletic group in Incheon that inspired the national spirit through sports under Japanese colonial era. It was a national athletic group that encouraged the pride of Koreans through sports.
Efficient Software-Based Encoding and Decoding of BCH Codes
Cho, Junho,Sung, Wonyong IEEE 2009 IEEE Transactions on Computers Vol.58 No.7
<P>Error correction software for Bose-Chaudhuri-Hochquenghem (BCH) codes is optimized for general purpose processors that do not equip hardware for Galois field arithmetic. The developed software applies parallelization with a table lookup method to reduce the number of iterations, and maximum parallelization under a cache size limitation is sought for a high throughput implementation. Since this method minimizes the number of lookup tables for encoding and decoding processes, a large parallel factor can be chosen for a given cache size. The naive word length of a general purpose CPU is used as a whole by employing the developed mask elimination method. The tradeoff of the algorithm complexity and the regularity is examined for several syndrome generation methods, which leads to a simple error detection scheme that reuses the encoder and a simplified syndrome generation method requiring only a small number of Galois field multiplications. The parallel factor for Chien search is increased much by transforming the error locator polynomial so that it contains symmetric exponents of positive and negative signs. The experimental results demonstrate that the developed software cannot only provide sufficient throughput for real-time error correction of NAND flash memory in embedded systems but also enhance the reliability of file systems in general purpose computers.</P>
