A single coronary artery (SCA) is a rare congenital anomaly. In most cases, it is an incidental finding on coronary angiography and has no clinical significance. However, it can cause angina, myocardial infarction, or even sudden death. Reports of SCA with acute myocardial infarction are very rare in the medical literature. This case study presents a patient with SCA from the right aortic sinus with severe stenosis in the proximal and distal part of the right coronary artery, which was detected using cardiac angiography and cardiac multidetector computed tomography (MDCT) with acute myocardial infarction.

DO, Trang Huyen,LE, Huyen Mong,LUONG, Diem Thuy Thi,TRAN, Quanh Thi Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.10

The study investigates the relationship between broad-scope management accounting information usage, market orientation, and the firm performance. This study employs a survey data of 149 top-level and mid-level managers working in Vietnamese tourism enterprises. To analyze research data, we employ SmartPLS 3 software. The analytical process include measurement model evaluation (evaluate the scale's validity and reliability) and structural model evaluation (test research hypotheses). The results reveal that broad-scope management accounting information usage has a positive direct effect on market orientation dimensions (include information generation, information dissemination, and responsiveness). Then, market orientation dimensions also have positive direct effects on the performance of Vietnamese tourism firms, excluding information dissemination. Moreover, this study also reveals that the market orientation dimensions mediate the relationship between broad-scope management accounting information usage and firm performance. The findings of this study suggest that tourism firms should pay more attention to the use of management accounting information in decision-making. With the increasingly fierce competition of the tourism firms today, capturing and meeting the needs of the market is a prerequisite to help firms enhance their competitiveness and improve their performance. To do that, Vietnamese tourism firms need to consider pursuing market orientation and enhancing broad-scope management accounting information usage.

Connectivity analysis of underground sensors in wireless underground sensor networks

Trang, Hoang Thi Huyen,Dung, Le The,Hwang, Seong Oun Elsevier 2018 Ad hoc networks Vol.71 No.-

<P><B>Abstract</B></P> <P>Wireless underground sensor networks consist of sensors that are buried under the ground and communicate through soil medium. Due to channel characteristics, the connectivity analysis of wireless underground sensor networks is more complicated than that in the traditional over-the-air wireless sensor networks. This paper focuses on analyzing the connectivity of underground sensors in wireless underground sensor networks in terms of the probability of node isolation and path probability which captures the effects of the environment parameters such as soil moisture and soil composition, and system parameters such as sensor node density and propagation techniques. Throughout this paper, both qualitative and quantitative comparisons between electromagnetic wave system and ordinary magnetic induction system for underground communications are provided. More specifically, we derive the exact closed-form mathematical expressions for the probability of node isolation of these two communication systems and validate the correctness of analytical models through simulations. We also provide the simulation-based path connectivity of these two communication systems. The results obtained in this paper provide useful guidelines on the design of reliable wireless underground sensor networks.</P>

이 글은 하노이와 베트남의 100년 동안의 역사를 통해서 동쪽과 서쪽, 남쪽과 북쪽의 상호문화적 교류를 분석한 글이다. 먼저 Accultureation의 용어 개념을 살펴보았다. 이어서 베트남과 중국문화의 관계를 경제적, 정치적, 문화적 상호교류의 관점에서 분석해 보았다. 나아가 무역부흥기를 살펴보고, 베트남과 프랑스의 관계를 중심으로 동쪽과 서쪽의 문화적 교류를 설명하였다. 특히, 베트남과 하노이의 문화 상호교류 과정을 통해서 베트남의 정체성과 문화적 본질을 규명해보고자 했다. 베트남의 남부와 북부에 있어서 정치적, 문화적, 경제적 변별성이 존재한다. 문학, 미술, 예술 특히 회화의 생성과 발전과정을 분석하고, 민속문화가 어떻게 조응하는지에 대해서도 살펴보았다. 인도차이나의 천년 수도인 하노이를 중심으로 호치민시와의 관련성 속에서 베트남 문화의 속성에 대해서 규명하고자 했다. This study has its purpose on analyzing cultural interactions of the east and the west and the north and the south with the 100 years" history of Hanoi and Vietnam. The study, first, considers the concept of the term, “Acculturation”, and subsequently analyzes the cultural relation between Vietnam and China with the view point of economical, political, and cultural interaction. Futhermore, the study examines the revival period of trades, and explains the cultural interchanges between the east and the west. Especially, the study would figure out Vietnamese identity and cultural essence with the cultural interaction process of Vietnam and Hanoi. There exist political, cultural, economical distinctions between the south Vietnam and the north Vietnam. At this aspect, the study also analyzes the generation and development process of literature, fine arts and art especially paintings. With the analysis, the study examines about how folk culture makes accordance. Ultimately, the study would like to figure out the attributes of Vietnamese culture in the relevance with Ho Chi Minh City centering into Hanoi where is the thousand-year capital city of Indochina.

The responsibility of C-terminal domain in the thermolabile haemolysin activity of Vibrio parahaemolyticus and inhibition treatments by Phellinus sp. extracts

The thermolabile haemolysin (tlh) of Vibrio parahaemolyticus (Vptlh) from V. parahaemolyticus is a multiple-function enzyme, initially describes as a haemolytic factor activated by lecithin and phospholipase A2 enzymatic activity (Shinoda, 1991; Vazquez-Morado, 2021; Yanagase et al., 1970). Until now, the tlh structure has hypothesized including N-terminal and C-terminal domain, but what domain of the Vptlh structure does the haemolytic activity has not been refined yet. In this study, a 450-bp VpTLH nucleotide sequence of the entire Vptlh gene encoded the C-terminal domain cloned firstly to examine its responsibility in the activity of the Vptlh. The C-terminal domain fused with a 6-His-tag named the His-tag-VpC-terminal domain was expressed successfully in soluble form in the BL21 (DE3) PlysS cell. Remarkably, both expression and purification results confirmed a high agreement in the molecular weight of the His-tag-VpC-terminal domain was 47 kDa. This work showed the His-tag-VpC-terminal domain lysed the erythrocyte membranes in the blood agar and the phosphate buffered saline (0.9%) media without adding the lecithin substrate of the phospholipase enzyme. Haemolysis occurred at all tested diluted concentrations of His-tag-VpC-terminal domain (p < 0.05), providing evidence for the independent haemolytic activity of the His-tag-VpC-terminal domain. The content of 100 μg of the His-tag-VpC-terminal domain brought the highest haemolytic activity of 80% compared to that in the three remaining contents. Significantly, the His-tag-VpC-terminal domain demonstrated not to involve the phospholipase activity in Luria-Bertani agar supplemented with 1% (vol/vol) egg yolk emulsion. All results proved the vital responsibility of the His-tag-VpC-terminal domain in causing the haemolytic activity without the required activation by the phospholipase enzyme. Raw extracts of Phellinus igniarus and Phellinus pipi at 10–1 mg/mL inhibited the haemolytic activity of the His-tag-VpC-terminal domain from 67.7% to 87.42%, respectively. Hence applying the His-tag-VpC-terminal domain as a simple biological material to evaluate quickly potential derivatives against the Vptlh in vivo conditions will accessible and more advantageous than using the whole of the Vptlh.

본 연구에서는 낯선 환경과 문화권에서 장애자녀를 양육하며 이중적 소외를 경험하고 있는 다문화가정 부모, 특히 여성결혼이민자의 한국사회 적응을 시작으로 장애 자녀의 양육, 특수교육 및 지원프로그램 참여 등 장애가정으로서의 경험에 대해 알아보고자 한다. 이를 위해 본 연구는 장애자녀를 둔 다문화가정의 부모를 대상으로 이루어졌으며, 서울, 경기, 인천, 경북에 거주하는 다문화가정의 부모 2쌍(필리핀, 베트남 출신의 여성 및 그들의 한국인 남편)과 여성결혼이민자 9명(필리핀인 2명, 중국인 3명, 베트남인 2명, 일본인 2명)을 포함한 총 13명을 연구 참여자로 선정하였다. 심층인터뷰는 개별로 이루어졌고 면대면 또는 전화인터뷰로 진행되었다. 분석 자료는 전사 작업을 통해 요인별, 영역별로 정리하여 범주화 되었으며, 이 결과는 “다문화가정 그리고 장애자녀의 부모”, “학교라는 높은 벽 그리고 작은 나”라고 하는 2개의 대주제와 5개의 하위 주제로 정리되었다. 연구결과를 바탕으로 장애자녀를 둔 여성결혼이민자 및 다문화가정이 직면한 어려움에 대한 이해와 특수교육 현장에서 이를 지원하기 위한 방안 등이 논의되었다. This study describes the experiences of multicultural families, especially female marriage immigrants having a child with disability in Korea. Using purposive sampling, semi-structured interviews were conducted with 2 sets of parents and nine mothers of children with disabilities. The interviews were transcribed and translated verbatim and analyzed using content analysis. Two main themes regarding multicultural families’ experiences were derived from the data: female marriage immigrants and their families; multicultural family and a parent of a child with disability; and their experiences and needs as working with professionals. Based on the results, implications for further studies and practice regarding serving multicultural families in special education system were discussed. It is also suggested that more cultural studies focusing on diverse population with specific needs should be conducted in further studies.
