현재, 우리나라 당뇨병의 유병률은 빠른 속도로 증가하고 있으며 당뇨병의 유병기간이 길수록 각종 합병증이 발생하여 더욱 심각한 증상을 나타는데, 그 중 비만 및 고혈당, 당대사장애로 인한 당뇨병성 혈관합병증과 말초 혈관 경화증이 많이 발병하고 있는 실정이다. 따라서 본 연구에서는 광혈류량 측정법(Photoplethysmography)으로 손가락 및 발가락에서 얻어진 맥파의 2차 미분분석을 통해 연령이 비슷한 정상인 50명과 당뇨병으로 확진된 50명의 말초 혈관 탄성도를 객관적으로 비교하고자 하였다. PPG 파형의 2차 미분 분석에 사용되는 평가 인자는 a, b, c, d, e 이고, b/a는 혈관의 탄성도를 의미하며 탄성도가 떨어질수록 b/a의 절대 값은 감소하게 된다. 정상인 50명의 PPG 2차 미분 b/a값은 -1.09±0.14, 당뇨병 환자 50명의 PPG 2차 미분 b/a값은 -0.81±0.09로 정상인에 비해 당뇨병 환자의 말초혈관 탄성도가 감소하였으며, Independen

Recently, there has been a steady increase in the interest of SI(Skeleton/Infill) housing. Infill technology is especially can be a useful means to a flexible and long life span housing. In this study, development trend and application cases of Infill technology in Korea and Japan are investigated. The result of this study are as follows; (1) In Japan, Infill technology is not only being improved in theory but also frequently applied to apartment housing such as KSI experimental housing and FH22

Bong-amsa Temple is a special temple in the custody of Jogye sect, a branch of Buddhism in Korea. Due to limited public access to this temple, its Geungnakjeon(paradise shrine) has been little known to outside. But it is known that the Geungnakjeon has been not yet explored from academic standpoints in terms of its historical establishment as well as applications, and it would be two-storied wooden pagoda or the like.In order to examine its historical establishment, this study investigated histo

The development of modern physics during the 20th century open a completely new understanding of the physical world. One of the key points a such understanding is shift from a notion of absolute space and particle oriented thinking to so called field theory which is the understanding the physical world not as composition of physical objects but as energy phenomena between the realm of feel that including both space and material as run interacting energy system.This paper asks whether such change

We are so used to the concept of the term "space" that we do not question its conceptual validity. However, this paper argues that the notion of space prevailing all over the world, is not a universal concept that can be applicable to all architectures of the world, but is a particular concept that is generated from the Western way of thinking. This paper aims to identify the conceptual structure of the idea of space as it is originated in the tradition of the West, and, as an alternative view o

Apartment houses are constructed with parts of the different size and life cycle. Establishing a proper timing of repair and replacement for the infill components of housing makes falling-off in quality of the housing, and satisfies the residents better for their qualitative and social demands in the rapidly changing era situation. This study understands a specific character of the repair cycle and replacements of the long life apartment Infill and searches for the cycle of the repair and replac

This is a study of Korean village in Yen-Bien, China. The village was investigated by extensive field research and analyzed from the scale of the whole village to the arrangement of each and every housing unit. Organic and irregular pattern of street system and lot organization strongly characterize the village as a Korean village compared to Chinese villages which are divided in a pattern that is more geometrically arranged. Besides, the pattern of site layout of individual housing including di

The Output-specifications in BTL for Education Facilities are the most important requirements in BTL Process. But the Output-specifications are not enough to protect the reduction of building quality. So, the Output-specifications need more details and need the change of role. And the Concept Design Phase after input-step of the Output-specifications are suggested to locate before the notification phase for RFP to the public. The Design Development Phase propose to be performed by proponents aft

Perception of architectural experience is different in different culture. This paper aims to identify how the experience of architecture is understood to be different in Eastern and Western culture. The discussion is based on the idea that the Western architecture placed more emphasis on visual perception, while the Eastern, on mutual responsiveness between man and built environment. The fact that the Western culture is more visually oriented than other culture, and therefore visual aspect of ar

The tradition of architecture in the East and the West are different in many ways. One of the basic cause of such difference, however, is the different ways of perception of space and time. This paper aims to identify the attitude of perception of space and time in the cultures of the East and the West, and its influence on architecture. Degrees of importance placed on either space or time, as well as the modes of perception of space and time are discussed in relation to architecture. Basically,

The Decision Process of BTL is quite different with that of general design process. In BTL process, the decision can be made by the Proponents. The Proponents are Investors, Operation and Maintenance Companies, Construction Companies and Architectural Firms.The Decision Process of the BTL Project in education facilities are depending on three major factors. These are 'Building Quality Factor', 'Limited Profit Factor' and 'Evaluation Factor'. Those Factors can grade problems which are appeared in

Excavated information of Buddhist temples of Koguryo built during the 5th century, have been roughly understood to be a kind of continuation of Chinese trend of Buddhist architecture. However, recent excavation report of Chinese temples of the 5-6th century, casts quite different possibility of interpretation. Since no evidence of octagonal pagoda and two image halls on each side of central pagoda, which are the two key features of Koguryo sites, were not found in Chinese cases, it seems quite e

All architectures in the history have certain attitudes of aesthetic expression of their own. Depending on the culture, such aesthetic attitudes are not the same but different. This paper aims to identify the nature of the difference of aesthetic attitude in the architectures of the East and the West. As a way of approach for this purpose, two keywords are employed as representative concept. They are: "proportion" and "vitality". Proportion, of course, represent the attitude of the Western, whil

본 논문에서는 여러 개의 참고입력을 사용하는 기존의 주파수 영역 협대역 잡음 제거기의 성능이 참고신호에포함된 협대역 성분과 광대역 방해 신호에 의해 결정됨을 보였다. 또한 기존의 협대역 잡음 제거기 보다 효율적이고빠른 수렴 속도를 얻기 위해 주신호와 참고신호들의 MSC(Magnitude Squared Coherence)를 사용하여 참고신호의SNR을 측정하고, 이를 바탕으로 적응 필터의 갱신 여부를 결정하는 새로운 협대역 적응 잡음 제거 기법을 제안하였다. 수식적 분석을 통하여 광대역 방해 신호의 영향을 분석하였으며, 제안한 기법이 기존 기법보다 더 우수한 성능을 보임을 확인하였다.

손자와 노자는 각 분야의 대가로 현대에서도 정치, 경영, 사회학에서 활발한 연구가 진행되어 왔다. 일반적으로 두 사상가는 상호연관성이 없는 것으로 여겨져 왔으나, 자세히 살펴보면 많은 부분에서 공통점을 가지고 있음을 알 수 있다. 이 논문에서는 두 사상의 공통점을 찾고 두 사상이 서로에게 미친 영향을 살펴보았다. 이를 위해 먼저 노자의 군사(軍事)에 대한 사상을 찾아서 손자의 사상과의 공통점을 살펴보았다. 다음으로 손자의 사상에서 찾을 수 있는 노자 사상과의 유사점을 탐색하였다. 그 결과, 손자의 세(勢)와 노자의 자연(自然)개념은 유사한 개념인 것을 알 수 있었다. 그리고 두 사상가 모두 중요한 개념으로 물(水)을 다루고 있음을 알 수 있었다. 또한 두 사상가의 전쟁에 대한 입장은 공통적으로 현실적 평화주의의 관점을 가지고 있으며 전쟁의 해악과 중대함에 대해서 충분히 인식하고 있음을 알 수 있었다.
