Background and Objectives : Cigarette smoking is a major factor and the most modifiable risk factor for atherosclerosis. Endothelial dysfunction is an early event in atherosclerosis, before the structural change of the systemic arteries. We hypothesized that endothelial dysfunction might be present in the systemic arteries of young adult smokers and that this might be dose-dependent phenomenon. Therefore, we try to certify that smoking is associated with endothelial dysfunction in healthy young adults without other risk factor of atherosclerosis. Subjects and Methods : we studied noninvasively 29 subjects aged 3 to 4 decades without other risk factor of atherosclerosis, they were composed of the two groups, current smokers(n=15) and nonsmokers(n=14). Smoking history varied from 3 to 20 pack years. Using high-resolution ultrasound, vessel diameter and mean flow rate were measured at rest, during reactive hyperemia(with flow-mediated endothelium-dependent dilation), and after sublingual nitroglycerin(NG-induced endothelium-independent vasodilation). Result : Flow mediated endothelium dependent dilation was observed in the control subjects (9.4±3.44%) but was impaired in the smokers(5.8±2.51%)(p=0.004). NG-induced endothelium independent dilation is no difference in all subjects. Conclusion : Cigarette smoking is associated with endothelial dysfunction in healthy young adults.

영도에서 조망하는 부산항 경관의 시각적 특성

박문순,강영조,조승래,강헌우,차명숙,Park, Moon-Sook,Kang, Young-Jo,Cho, Seung-Rae,Kang, Hyon-Woo,Cha, Myeong-Sook 한국조경학회 2010 韓國造景學會誌 Vol.38 No.4

본 연구는 영도에서 부산항을 체험할 수 있는 조망점을 대상으로 조망점의 공간적 분포, 부산항을 체험하는 시선의 유형, 항구경관의 구도적 특성 그리고 조망점의 시각특성을 밝히고자 하였다. 선정된 조망점 27개소를 대상으로 한 연구의 결과는 다음과 같다. 첫째, 조망점의 공간적 분포 유형은 공원형, 공공시설형, 도로변형으로 구분되었다. 조망점은 도로변형에서 가장 많이 분포하는 것으로 나타났다. 둘째, 부산항을 체험하는 시선의 유형은 수제선회유형, 항만대변형, 도시관통형으로 나타났다. 영도에서 바라보는 부산항 경관에 대한 시선의 유형은 도시관통형이 가장 많이 나타났다. 이유로는 영도라는 섬이 도시화로 인해 시가지와 도로가 점점 확장되면서 부산항을 바라보는 시선이 도시를 관통하여 바다를 조망하는 시선이 많아지게 된 것으로 보인다. 셋째, 항구경관의 구도적 특성은 파노라마형, 회랑형, 지붕너머형으로 파악되었다. 그 중 지붕너머형이 가장 많이 나타났다. 이를 통해 영도에서 체험하는 부산항의 모습은 대부분 경관의 연속성이 상실되고, 주거지의 지붕이 거리감을 차단하여 일종의 차경 역할을 하는 것을 알 수 있었다. 마지막으로 조망점의 시각특성을 분석하였다 조망정의 부각은 수평경에 가까운 $-3^{\circ}{\sim}-1^{\circ}$사이에 13개소, $-6^{\circ}{\sim}-4^{\circ}$의 범위에 12개소로 가장 많은 분포를 보였다. 부감의 시축에 해당되는 조망점은 2개소로 나타났다. 이는 시가지가 확장되면서 건물에 의해 내려다보는 시선이 차단된 결과로 판단되었다. 그리고 시거리의 지리적 범위는 0.2km~6.4km에 이르는 광범위한 조망역을 이루고 있었다. 최적의 부감경을 체험할 수 있는 조망점 2개소는 지속적으로 조망을 보전하기 위한 방법을 제안하였다. 본 연구의 성과는 부산의 경우와 같은 항만도시에 있어서 조망점의 관리 및 보전 등의 경관계획에 기초자료로 활용할 수 있을 것으로 기대한다. This study will define the features of the viewpoint that best enables the view of Busan Port from Young-Do. Special focus will be on spatial distribution, the type Busan Port sights that can be experienced from Young-Do, the compositional characteristic of a port landscape and visual characteristic. The results are based on 27 selected viewpoints and are as follows. Firstly, the patterns of the spatial distribution of viewpoints are classified as park, public facility and wayside types. It was found that most viewpoints are located along a wayside. Secondly, the types of Busan Port sights that can be experienced from Young-Do are divided into three kinds: surrounding stand-line type, facing the port and the type of penetrating city. The major type was of penetrating city among the three patterns. The reason for this is that the point of view for Busan Port was changed into a prospect over the sea since city and road sections have been expanding due to the urbanization of Young-Do. Thirdly, the compositional characteristics of the port landscape are divided into three styles: panoramic, corridor, and rooftop. The most frequent type is the rooftop style among the three characteristics. This fact indicates that the picture of Busan Port seen from Young-Do loses continuity of view and that housetops inhibit the sense of distance. Lastly, the visual characteristics of the viewpoint were analyzed. The angles of the declination of the viewpoints are concentrated on the horizontally closed parts. Thirteen points lie between $-3^{\circ}$ and $-1^{\circ}$, and twelve points between $-6^{\circ}$ and $-4^{\circ}$. The visual axes of the depression are two points because sight is interrupted by buildings which are built when the city expands. Two viewpoints for experiencing the optimum landscape of depression should be prepared to ensure continuous preservation of the viewpoints. The sight creates a wide prospect, reaching from 0.2km to 6.4km. It is expected that the results of this study can be used for the landscape plans of port cities including the management and preservation of viewpoints.

이청준 소설에 나타난 도시공간과 낭만성의 상관관계

이현영(Lee, Hyon-young) 한국어문학회 2017 語文學 Vol.0 No.136

The purpose of this article is to examine the urban aspects embedded in Lee Chung-jun’s literary works where characters struggle to conform to the cultural norms and social order derived from capitalist reality of living in urban space. Therefore, Lee’s motivation of writing has been known as “vengeance on the world,” as the writer’s perception of reality was shaped by his urban experiences of poverty and loneliness. However, his literary world contains a positive view of urban reality. It often conveys his innate interest and exotic gaze on the city, and his desire is presented in a form of romantic view. In this respect, this article traces the descriptions of urban life in Lee Chungjun"s writings and explores how the text engages in various urban experiences. In the second section, the article provides a theoretical foundation to define the “exotic gaze” on the urban space and the analyzes the stories reflecting romantic aspiration of the city. The following section focuses on the literary configuration of the characters who vacillate between envy and disgust while living in the capitalist world and reveals the writer’s ambivalent attitude toward the city in his early stories.

김현철,김용우,최영규 서울保健大學 1996 論文集 Vol.16 No.1

Combination letter forms have a plastic problem and a study on this has not progressed until now. Thus this study will propose a reform measure for the design of combination letter forms on the basis of the principle of "Unity of Variety." The height of a final on the end of korean orthographic syllable applied to the proportion by harmonic progression or the proportion principles including an irrational number as a substitute of the plastic problem for combination letter forms give the diversity and the uniformity, It is unstandable as the letter form having rhythmic property when connecting this. The reform measure of combination letter forms applied to this "Unity of Variety" is as follows : 1) The proportion principles gives it the rhythmic expression, while the existing combination letter forms with no consistency have people feel a rejection symptoms. 2) This letter forms have the harmony with uniformity and variety properly, while the completion forms give emphasis to the uniformity excessively. 3) The size are different between the many stroke and the small number of stroke, which have high readability. 4) The distance between "하" and "ㄴ" become narrower with a final on the end of korean orthographic syllable having small stroke make its height lower. The letter with many stroke like "ㄹ" having its height higher make high readability. 5) Applying the serif role of alphabet which gives the simplicity and the arrangement of charaters to the serif of combination letter forms provide the uniformity and the readability as it is possible to read it as a connected line, not distinguishing as a character by a character.

Redundant Binary Booth Encoding을 이용한 FIR 필터 코어의 설계

장영진,이현수 경희-다반 ASIC 설계교육센터 2000 경희-다반 ASIC센터 논문집 Vol.1 No.-

In this paper, we propose the architecture of a fast programmable FIR filter core that can be used in digital signal processing demanding high-speed and high-order digital filtering. To reduce the complexity of multiplication and addition, we adopt a redundant binary representation. It can perform addition in a constant time independent on the word length of multiplicand. Since FIR computing needs addition proportion to the size of tap, fast addition and reduction method plays a key role in implementing a fast FIR filter. The proposed method results more than 100M/s. And it has a programmability and scalability for use a variety of signal processing.

능동 시청각 시스템을 위한 MPSoC 구현

김영진,이현수 경희-다반 ASIC 설계교육센터 2007 경희-다반 ASIC센터 논문집 Vol.8 No.-

능동 시칭각 시스템은 시각과 청각에 대한 정보를 수집하는 과정에서 보다 더 좋은 정보를 얻기 위해 능동적으로 반응 할 수 있는 시스템을 말한다. 능동 시청각 시스템은 인식괴 행동을 수행 할 수 있는 모든 분야에서 필요한 기능이다. 능동 시각 시스템과 능동 청각 시스템은 독립적으로 구현하는 경우가 많으나, 시각 시스템은 이미지 센서에 의존함으로 이미지 센서 밖에서 얼어나는 일에는 는동적으로 반응 할 수 없으며, 센서의 모든 영역에 대한 연산 처리량이 많다는 단점을 갖고 있다. 또한 청각 시스템은 능동적으로 반응하도록 시스템을 구연하면, 모터의 잡음이나 주위 환경에 의해서 정확한 위치를 판단하기가 어려운 단점을 갖고 있다. 그러므로, 두 시스템의 단점을 보완하기 위해서 통합시스템을 구현할 필요성을 갖고 있다. 또한 시각과 청각 정보는 동시에 발생할 경우가 많음으로 두가지 시스템을 병렬로 구현할 필요성을 가지고 있다. 따라서, 본 논문에서는 능동 시청각 시스템을 MPSoC(MultiProcessor System On Chip)로 구현함으보써 능동 시각으로서 제한된 시야의 한계를 극복하고, 시선의 집중을 통해 연산량을 줄이든데 목적이 있다. 또한 각 프로세시가 병렬로 동작함으로써 동시에 발생하는 두가지 정보를 병렬로 처리할 수 있도록 구현하였다.
