This study is to analyze the residential spatial composition structures of vernacular agricultural village which to be called Wanggok in Yeongdong area. The results of this study are as follows; ${\cdot}$ The backyard of farmhouses is surrounded by a fence and a frontyard is open to the road, so that the spatial realm system from the road to the backyard is classified as public-semi public-private realm. ${\cdot}$ The plan type of this village is mainly composed of ㅡ type Gyeobjib (the two row rooms under one roof) and ㄱ type Gyeobjib, the Anmaru (the inner wood floor to be surrounded with wall) in both of which plays an important role that connects Sarangbang (the men's main room) with Anbang (the women's main room) in the residential space. ${\cdot}$ The particular item that not found out in another area is the Sarangbang kitchen which located to Sarangbang's side wall to be furnished with a fire hole. ${\cdot}$ The houses represent the socio-cultural environmental elements of those built days, such as while Sarangbang is faced on a frontyard to be open to the neighborhood, Anbang is faced on a backyard surrounded with a fence to be closed to the one. ${\cdot}$ The Gyeobjib with Anmaru appeared by cultural transformation connecting the 田-shaped house of Hamgyeongdo with the Gyeobjib with Anmaru of Gangwondo and Gyeongsangbukdo. ${\cdot}$ The ㄱ type Gyeobjib is preferred to ㅡ type Gyeobjib because of the sea wind and the north-east wind occurring by geographical and climatic environment elements, the privacy protection according to look into a frontyard, the muck drainage of cowshed to make use of ground unevenness, the economic gains called material saving and the intention to enlarge the frontyard as to be concentrated in a residential space and etc.

Digital radiographic systems based on solid-state detectors, commonly referred to as flat-panel detectors, are gaining popularity in clinical practice. Large area, flat panel solid state detectors are being investigated for digital radiography. The purpose of this work was to evaluate the active matrix flat panel digital x-ray detectors in terms of their modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). In this paper, development and evaluation of a selenium-based flat-panel digital x-ray detector are described. The prototype detector has a pixel pitch of $139\;{\mu}m$ and a total active imaging area of $14{\times}8.5\;inch^2$, giving a total 3.9 million pixels. This detector include a x-ray imaging layer of amorphous selenium as a photoconductor which is evaporated in vacuum state on a TFT flat panel, to make signals in proportion to incident x-ray. The film thickness was about $500\;{\mu}m$. To evaluate the imaging performance of the digital radiography(DR) system developed in our group, sensitivity, linearity, the modulation transfer function(MTF), noise power spectrum (NPS) and detective quantum efficiency(DQE) of detector was measured. The measured sensitivity was $4.16{\times}10^6\;ehp/pixel{\cdot}mR$ at the bias field of $10\;V/{\mu}m$ : The beam condition was 41.9\;KeV. Measured MTF at 2.5\;lp/mm was 52%, and the DQE at 1.5\;lp/mm was 75%. And the excellent linearity was showed where the coefficient of determination ($r^2$) is 0.9693.

This Study took a general view of the measure of a historical environmental preservation in France. Moreover, this study examined le Marais, the Louvre museum, and the orsay museum as a historical environment of Paris. Especially, the Louvre museum is the one that a building was extended underground as architect I.M.Pei uses existing Louvre as it is. That is, the preservation technique of the Louvre museum is it concept of whole preservation by which an existing connection is maintained. On the other hand, the orsay museum became an internal remodeling and a museum while preserving externals of an existing station. The orsay museum is a case where the conflict which exists during the construction in an old age and the constriction at the present age is effectively solved.

저자들은 1988년 9월 가톨릭대학부속 성모병원에서 임신 11주 1일에 절박유산, 고위험임신으로 입원하여 임신 15주 3일에 자궁경관 무력증으로 MacDonald수술을 시행, 수술 5병일째 조기파막이 일어나 196일간의 장기간 입원으로 절대적인 안정가료 및 집중적인 항생제투여와 자궁수축 억제제의 치료로 건강한 정상적인 아이를 분만하였기에 간단한 문헌적 고찰과 함께 보고하는 바이다. Premature rupture of membrane(PROM) represents confusing and controversial dilemas at the time for terminating pregnancy and treatment in Obstetrics today. After PROM, immediate preterm delivery yioios a low-birth-weight infant and prematurity which increase neonatal morbidity and perinatal mortality but, attempt to intrauterine growth, in despire of PROM, increases the risk of infection for the mother and fetus. We experienced a case of successful term delivery in early pregnant woman with PROM and report with a brief review of concerned literatures.
