Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

A Study of the Yang-gyeong-gyu-il-ui (兩景揆日儀) in the Joseon Dynasty

Lee, Yong Sam,Kim, Sang Hyuk,Mihn, Byeong-Hee The Korean Space Science Society 2015 Journal of Astronomy and Space Sciences Vol.32 No.1

The Yang-gyeong-gyu-il-ui (兩景揆日儀) is a kind of elevation sundial using three wooden plates. Sang-hyeok Lee (李尙爀, 1810~?) and Byeong-cheol Nam (南秉哲, 1817~1863) gave descriptions of this sundial and explained how to use it in their Gyu-il-go (揆日考) and Ui-gi-jip-seol (儀器輯說), respectively. According to Gyu-il-go (揆日考) there are two horizontal plates and two vertical plates that have lines of season and time. Subseasonal (節候) lines are engraved between seasonal (節氣) lines, subdividing the interval into three equal lines of Cho-hu (初候, early subseason), Jung-hu (中候, mid subseason) and Mal-hu (末候, late subseason); there are 13 seasonal lines for a year, thus resulting in 37 subseasonal lines; also, there are 12 double-hour (時辰) lines for a day engraved on these plates. The only remaining artifact of Yang-gyeong-gyu-il-ui was made in 1849 (the $15^{th}$ year of Heon-jong) and is kept at the Korea University Museum. We have compared and analyzed Yang-gyeong-gyu-il-ui and similar western sundials. Also, we have reviewed the scientific aspect of this artifact and built a replica. Yang-gyeong-gyu-il-ui is a new model enhanced from the miniaturization development in the early Joseon Dynasty and can be applied to the southern part of the tropic line through a structure change.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Electronic water pump(EWP) of vehicle automatically can run engine cooling function regardless of engine speed, so that it reduces remarkably fuel consumption. A numerical analysis was carried out in order to optimize the impeller and volute design for EWP and to investigate the sensitivity of the related parameters using CFD commercial code FLUENT V14.5. The feasible range of related parameters for EWP was obtained. The obtained result will be applied to develop EWP as important design data

침입탐지에서 지지율 기반 클러스터링을 이용한 정상행위 패턴 생성

오상현,장중혁 대구대학교 정보통신연구소 2010 情報通信硏究 Vol.7 No.1

For effectively detecting the intrusion through computers, many algorithms have been actively proposed so far, and recently the works related to anomaly detection, which is extended from misuse detection techniques by reducing their drawbacks, have attracted considerable attention since the anomaly detection technique can identify unknown intrusion methods. In this paper, a new clustering algorithm is proposed in order to extract patterns from the normal user activities. For the purpose, the anomalous user behaviors should be analyzed in various angles, and be classified by many different types of measures. 컴퓨터를 통한 침입을 효과적으로 탐지하기 위해서 많은 기법들이 제안되어 왔으며, 근래에는 오용 탐지 기법을 개선하기 위해서 비정상행위 탐지 기법에 관련된 연구들이 활발히 진행중이다. 본 논문에서는 침입탐지에서 정상행위 패턴을 생성하기 위해 지지율에 기반한 새로운 클러스터링 알고리즘을 제시한다. 이를 위해서 정상적인 사용에 대한 행위를 다양한 각도에서 분석될 수 있도록 여러 판정요소로 분류하고 각 판정요소에 대해서 제시된 알고리즘을 이용하여 정상행위 패턴을 생성한다.

본 논문에서는 신호의 분리와 합성이 가능한 Diplexer를 제작하였다. 저역 통과 여파기와 고역 통과 여파기의 특성을 정합하여 Diplexer로 구현함으로써 신호의 분리와 합성이 가능하다는 것을 시뮬레이션을 통해 확인하였다. 또한 신호의 분리와 합성의 가능성을 입증하기 위해 실제 마이크로스트립구조의 Diplexer를 제작, 측정한 결과 각각의 통과 대역폭 내에서 0.4dB, 0.8dB이내의 삽입손실과 -20dB의 반사손실이 됨을 실험결과를 통해 알수 있었고 또한, 인덕터의 구현 방법을 마이크로스트립으로 하여 주파수 특성과 재현성을 높였다.

석분과 황토를 사용한 건자재 제품 개발 연구

성찬용,류능환,윤준노,김영익,임상혁 강원대학교 부설 석재복합신소재 제품연구센터 2003 석재연 논문집 Vol.8 No.-

본 연구는 석분과 황토를 사용한 건자재 제품을 개발하기 위하여 황토의 첨가량를 5종류, 석분의 첨가량을 3종류로 하여 총 16종류의 모르타르에 대하여 단위중량, 흡수율, 압축강도, 휨강도, 동탄성계수, 초음파진동속도, 중성화 깊이에 대하여 구명하였다. 단위중량, 압축강도, 휨강도, 동탄성계수 및 초음파진동속도는 황토와 석분의 사용량이 증가할수록 감소하는 경향을 나타내었고, 흡수율과 중성화 깊이는 증가하는 경향을 나타내었다. 주사전자현미경에 의한 관찰에서는 비활성황토의 사용량이 증가할수록 결정이 증가한 것으로 나타났다. 황토의 사용량은 강도적인 측면에서는 결합재량의 40%까지 사용이 가능하고, 흡수율 측면에서는 10%까지 사용이 가능하며, 건자재의 사용목적에 따라 황토의 사용량을 조절하는 것이 필요할 것으로 생각된다. The purpose of this study is to obtain the basic data for the development of construction materialproducts using stone dust and non-active Hwangto. The results of physical and mechanical properties were as follows. The unit weight, compressive and flexural strengths, dynamic modulus and ultrasonic pulse velocity are decreased with increase of the stone dust and Hwangto. The absorption ratio and neutralization depth are increased with increase of the stone dust and Hwangto. In the results of SEM analysis, the crystals are increased with increase of the non-active Hwangto. Accordingly, the Hwangto may be suitably used as a cement replacement material in the construction material products.

영어와 한국어 어법의 차이

김상혁 한국교통대학교 2020 한국교통대학교 논문집 Vol.55 No.-

The purpose of this article is to explain the usage difference between English and Korean. Certain common problems would emerge among Korean speakers as they approach English through analogies with their first language, Korean. So sometimes Korean English, Konglish, is spoken and written by Koreans. This article focuses on problems that occur when Koreans use English as a means of communication. We can say a problem in communication has occurred whenever speakers fail to convey what they want to, or when they express something different from what they want to. Koreans sometimes use words and phrases to mean something different from what native English speakers mean by the same expressions. For example, the Korean-English use of word, ‘promise’ differs from the standard English meaning of that word in ways that can lead to very serious misunderstanding. Such confusions of meaning are ‘problems’ in a very obvious sense. While ‘yaksok’ can mean either ‘promise’ or ‘appointment’, in English these two ideas are clearly distinguished. In English, the word, ‘promise’, does not mean ‘an appointment’. These problems are apt to occur frequently whenever Koreans speak English where in day-to-day communication. The goal of this paper is to help Koreans to overcome the problems in their spoken production. We strongly recommend that Korean students put most of their energy into reading and understanding the examples of correct sentences.
