본고(本稿)는 우리 경제의 개방화(開放化) 자율화(自律化) 추세 속에서 거시경제정책수단(巨視經濟政策手段)으로서의 재정정책(財政政策)의 기능과 역할에 대해 다음의 두가지 방안을 제시하고 있다. 첫째로, 분기별(分期別) 통합재정통계(統合財政統計)를 이용한 실증분석 결과에 기초해서 안정적 경제운영(經濟運營)에 있어서 통합예산관리(統合豫算管理)의 중요성을 강조하였다. 분석결과, 기존의 연간자료를 이용한 분석에서 밝혀진 바와 같이 물가 상승률과 재정적자 변수간에 정(正)의 상관관계가 존재하는 것으로 나타났으며, 총통화 변수와 재정수지(財政收支)를 포함하는 물가상승률의 추정식 결과를 이용해서 단기적인 통화(通貨) 재정변수(財政變數)의 적정조합을 모색해 볼 수 있다. 다른 조건이 일정하다면 연간 총통화 증가율 1%포인트와 재정적자(財政赤字)의 대(對)GNP 비율 1%포인트 증가가 평균적으로 비슷한 정도의 물가압력을 낳는 것으로 나타난다. 둘째로, 효율적인 거시경제운영(巨視經濟運營)을 위해 요구되는 재정의 보다 근본적인 역할재정립 방향에 대해서 논의하였다. 해외자본유입(海外資本流入) 등에 대비하기 위해서는 신축적인 통화관리여건이 조성되어야 하고, 이를 위해서는 한은대출에 의한 정책금융 지원분의 재정이관 문제가 보다 적극적 전향적으로 검토되어야 한다. 총액한도대출대상 정책금융 중 지방중소기업자금의 이관문제가 검토되어야 하며, 상업어음할인, 무역금융, 소재 부품생산자금의 경우 기존의 중소기업지원관련 기금에 대한 출연을 확대해서 단기운전자금의 대출 등을 담당하게 하는 방안을 검토할 필요가 있다. 또한 총액한도대출대상 정책금융이 중소기업에 대한 지원인 점을 감안할 때, 중소기업부문(中小企業部門)에 대한 재정지원체계(財政支援體系)를 금리자유화 일정 등을 감안하여 종합적으로 정비함으로써 총액대출한도의 축소를 유도하는 역할을 재정이 담당해야 할 것이다.

차세대 하이테크 스마트 의류는 복합 차원에서의 감성적인 요소를 섬유 패션기술에 IT융합 기술을 이용하여 제공하고 있다. 생체신호를 이용한 감성은 모호하여 정량적이고 객관적인 측정이 어렵고, 그 표현도 제한된 감성 어휘에 의하여 나타나기 때문에 구체적으로 파악하는 것은 어려운 일이다. 이를 위하여 제품의 기능적 측면뿐만 아니라 정서적 감정과 선호도가 반영된 제품의 설계나 디자인 또한 요구되고 있다. 본 논문에서는 생체신호 측정을 위한 웨어러블 기반의 심전도 측정 의복을 제안하였다. 착용자가 평소 자주 입는 티셔츠를 응용하여 답답해하거나 불편하지 않게 제작하고 소매 형태로 신축성있는 소재를 사용한다. 인체의 형태에 따라 의복과 바이오센서의 전극이 안정적으로 밀착될 수 있도록 고탄력 밴드를 이용하여 일자형으로 제작하였다. 심전도 측정 의복을 착용에 의해 수집된 심전도 ECG 파형을 수집하고 심박변화율을 계산하는 시뮬레이션을 개발한다.

Recently, Study of functional clothing for Vital sensing is focused on reducing artifact by human motions, in order to enhance the electrocardiogram(ECG) sensing accuracy. In this study, considering the factors for each element found from the analysis, a 3-lead electrode inside textile embroidered with silver yarn was developed, and draft designs off our types of vital-signal sensing garments, which are 'chest-belt typed' garment, 'cross-typed' garment 'x-typed' garment and 'curved x-typed' garment, were prepared. The draft designs were implemented on a sleeveless male shirt made of an elastic material so that the garment and the electrodes can remain closely attached along the contour of the human body, and the acquired data was sent to the main computer over a wireless network. In order to evaluate the effects caused by body movements and the ECG-sensing capability for each type in static and dynamic states, displacements were measured from one and two dimensional perspectives. ECG measurement evaluation was also performed for Signal-to-noise ratio(SNR) analysis. Applying the experimental results, the draft garment designs were modified and complemented to produce two types of modular approaches 'continuous-attached' and 'insertion-detached' for the ECG-sensing smart clothing.

The purpose of this study was to analyze fabrics suitable for use as examination gowns to determine whether examination gowns affect imaging during anterior to posterior chest examinations(Chest AP) on a digital X-ray system. Examination gowns in use at five medical centers in Seoul were collected and included modal, tencel, cotton, and rayon fabrics. The selection of fabrics was based on studies that reported fabrics with good tactile, absorbent, stretchable, and wrinkle resistance. Phantoms of five hospital gowns and four fabrics, arranged in overlapping layers from one to eight, were created and examined on a digital X-ray system in both Chest AP examination. The images examined were subjected to a first-step profile analysis, a second-step signal intensity averaging analysis, and a third-step microscopic analysis. The results showed that all nine materials had an increasing impact on the image as the number of layers of fabric increased, with the modal fabric having the least impact on the image in the first, second, and third analyses. In conclusion, as the resolution of digital x-ray systems increases, the impact of examination clothing on the image will increase, and research to find suitable materials for examination clothing will continue to be necessary.

Structural changing materials which can induce the physical deformation of materials are interesting research topics with various potential applications. Particularly, light among many driving mechanisms is a non-contact energy source, hence the light-responsive system can be used where non-destructive, local irradiation, and remote control is needed. Here, a mainchain azobenzene polymer is synthesized and its physical and optical properties are observed and compared to that of a polymer having a light-responsive azobenzene moiety on its side chain. Further dispersion onto polyvinylalcohol hydrogel is made and its dual stability and actuation are observed upon UV-visible light irradiation. Extended azobenzene polymer blend films show an anisotropic light-actuation with non-polarized UV light at room temperature. This physical shape change is quite reversible and occurs at lower temperature than that of any other reported systems including liquid crystalline elastomers. It is successfully demonstrated that the simple physical azobenzene/polymer blending has a very good actuation compared to that of LCEs which need an elaborate chemical design and it can be further used in the areas requiring a dimensional shape change.

EIFS system has the merit of low construction cost and shortening of construction period by easy-to-construct. For such reasons as mentioned above, it has been using across the board such as residential building, school, officetel, building remodeling and so on. It, however, has a drawback of generating plenty of combustible gases from styrofoam which is main material of it. In this regard, measures to prevent losses of life from combustible gases are needed urgently as fires on residential buildings applied EIFS caused human casualties resulted from combustible gases. With respect to the above, this study will analyze the risk of fires on residential facilities, such as multi-family apartment houses, schools and other buildings, applied EIFS which is the most frequently used as material of exterior wall and suggest countermeasure of it.
