District units plan si a plan implementation for the promotion of friendly urban environment, where human beings coexist with nature in certain area in a city. This concept, supports sustainable urban development and management, and improves urban infra-structure facilities and buildings for urban function and streetscape. However, related regulations and standards, which is necessary for height limitations to decide a street scenic beauty for open view and sky line are under consideration and not established. Currently, the zoning ordinance does not specifies height limitation in relation with city dimension, while oblique line regulation based on the road width has been a measure for height control. Therefore, this study aimed to analyze the relationship between base floor area ratio and oblique line limitation standard for the maximum height standard in district unit plan. The majer research findings were as followings: 1) Specific height control standard conforming to local urban context is necessary; 2) Uniform standard of 1 : 1.5 ratio does not shows optimum building scale; 3) The analysis of rerationship between road width and oblique line limitation suggests height control of 1 : 1.8 ratio rather than 1 : 1.5 ratio in general commercial district.

Background: Power spectrum analysis method is a powerful noninvasive tool for quantifying autonomic nervous system activity. In this paper, we developed a data acquistion system for estimating the activity of the autonomic nervous system by the analysis of heart rate and respiratory rate variability using power spectrum analysis. Materials and methods: For the detection of QRS peak and measurement of respiratory rate from patient's ECG, we used low-pass filter and impedance method respectively. This system adopt an isolated power for patient's safety. In this system, two output signals can be obtained: R-R interval(heart rate) and respiration rate time series. Experimental ranges are 30∼240 BPM for ECG and 15∼80 BPM for respiration. Regults: The system can acquire two signals accurately both in the experimental test using simulator and in real clinical setting. Conclusion: The system developed in this paper is efficient for the acquisition of heart rate and respiration signals. This system will play a role in research area for improving our understanding of the pathophysiologic involvement of the autonomic nervous system in various disease states.

Structural ceramics have been widely used in engineering parts. It, however, is very difficult to grind the ceramics with desired shape and dimensional accuracy because of their high hardness, strength, and brittleness. Grindability of structural ceramics are quite different as they have different mechanical and physical properties. This paper compares the grindability of structural ceramics such as Al₂O₃Si₃N₄and SiC. The grinding experiments include the measurement of grinding force, surface roughness. and SEM observation. The experimental results indicate that Si₃N₄consumes the highest specific grinding energy among the three kinds of ceramics. It was also found that there is no corelationship between grindability and surface roughness of ground surface.

목 적 : 장티푸스는 체액의 세균배양검사에서 Salmonella typhi의 분리로 확진하지만 조기진단을 위해서는 혈청학적인 검사가 도움이 된다. 저자 등은 1989년 이후 장티푸스진단에 S. typhi의 Vi항원을 이용한 간접형광항체법 (Vi-indirect fluorescent antibody test : Vi-IFAT)을 도입하였다. 이에 지난 7년간의 검사결과를 토대로 Vi-IFAT의 민감도 및 특이도를 규명하고자 하였다. 방 법 : 1989년부터 1996년까지 연세대학교 의과대학 세브란스 병원에 발열을 주소로 내원하여 Vi-IFAT가 의뢰된 환자 중 발열의 원인이 확진된 744명의 환자를 대상으로 하였으며, Vi-IFAT에 있어서 양성반응은 1:64이상으로 하였다. 결 과 : 1) 세균배양검사에서 확진된 장티푸스 환자 178예 중 168예에서 양성반응을 보여 민감도는 94.4%이었다. 항체가는 1:64가 89예, 1:128이 36예, 1:256이 27예, 그리고 1:512가 16예이었다. 위음성이었던 10예의 항체가는 1:32가 7예, 1:16이하가 3예이었다. 2) 발열을 주소로 내원한 환자 중 장티푸스 이외의 다른 질환으로 확진된 566예 중 538예에서 음성반응을 보여 특이도는 95.1%이었다. 항체가는 1:32가 117예, 1:16이하가 421예이었다. 위양성이었던 28예의 항체가는 1:64가 23예, 1:128이 5예이었으며, 장티푸스 이외의 살모넬라증이 4예, 요로계감염이 10예, 소화기계감염이 6예, 호흡기 계감염이 5예, 악성 종양이 2예, 그리고 바이러스 감염이 1예이었다. 3) Vi-IFAT 양성인 196예 중에서 장티푸스는 168예로 양성예측율은 85.7%이었으며, Vi-IFAT 음성인 548예 중 장티푸스 이외의 발열질환은 538예로 음성예측율 98.2%이었다. 4) 배양검사와 Widal test 사이의 일치율 (Kappa value)는 0.28로 poor agreement를 보였으며 Vi-IFAT와 Widal test 사이의 Kappa value는 0.74로 good agreement를 보였다. 그러나 배양검사와 Vi-IFAT 사이의 Kappa value는 0.86으로 excellent agreement를 보여 일치율이 가장 높은 검사는 배양검사와 Vi-IFAT라 할 수 있겠다. 5) 장티푸스 환자에 있어서 Vi-IFAT의 양성율은 발열기간이 1중 미만인 환자에서는 68%, 1내지 2주인 환자에서는 89.5%, 2주이상인 환자에서는 100%이었다. 결 론 : Vi 항원을 이용한 간접형광항체법 (Vi-IFAT)은 장티푸스 진단에 높은 민감도 및 특이도를 가지며, 또한 조기진단에 있어서도 임상적으로 유용함을 확인할 수 있었다. Background : Typhoid fever is diagnosed by culture or serological study. The confirmative diagnosis of typhoid fever is made by culture of the causative organism usually from body fluids. Serological test is a supportive diagnositic tool, which is useful for early diagnosis. In Severance Hospital, Vi-indirect foluorescent antibidy test(Vi-IFAT) using the Vi-antigen of Salmonella typhi has been used in the diagnosis of typhoid fever since 1989. We investigated the test results from the past 7 years, in order to clarify the sensitivity and specificity of Vi-IFAT. Methods : A retrospective study was done on patients whose chief complaint was fever and who were tested using Vi-IFAT in the Severance Hospital from 1989 to 1996. The positive value for Vi-IFAT was defined as 1:64 or higher. Results : The sensitivity and specificity of Vi-IFAT for typhoid fever was 94.4% and 95.1%, respectively. The positive and negative predictive values were 85.7% and 98.2% respectively. Positive rates of Vi-IFAT after fever onset increased with time and 68% were positive before the first week. From the first to the second week, 89.5% were positive and after the second week, 100% were positive. Conclusion : Vi-IFAT is not only a valuable serologic test for the diagnosis of typhoid fever, but also useful in the early diagnosis of the disease.

The waste to energy is a way to solve the problem about depletion of fossil fuels and reliable supply of energy. The amount of electricity produced by waste to energy were investigated to account for about 56% of all electricity produced by renewable energy in 2016. Furthermore, solid refuse fuel(SRF) have advantages in the case of the facility operation. Because it is easier to control complete combustion and air pollutants compared with general waste. Also, SRF have a higher calorific value than general wastes, and therefore, it is considered to be advantageous in terms of energy recovery. However, there is a lack of objective and scientific data on the energy recovery efficiency of SRF plants. Accordingly, it is necessary to provide objective and scientific basic data on energy recovery efficiency of SRF plants. This study was conducted on two SRF plants. This study content is that evaluates the energy recovery efficiency and potential energy by analyzing the energy production and utilization status. The average lower heating value of the SRF plants was the average 3,211.51kcal/kg calculated by heat balance. And energy recovery efficiency was estimated to be about 61.77% for the SRF plants. However, the potential energy is about 41.96% for SRF plants. This study was supported by a grant the National Institute of Environmental Research (NIER), funded by the Ministry of Environment (MOE) of the Republic Korea (NIER-2018-01-01-048)

The Mediator complex is generally required for tran-scriptional regulation In species ranging from yeast tohuman. Throughout evolution, the functional diversityof the Mediator complex has been enhanced to meet theincreasing requirements for sophisticated gene regula-tion. It is likely that greater structural complexity isthus required to accomplish these new, complex regula-tory functions. In this study, we took systematic steps toexamine various types of Mediator complexes inDro.sophila melanogaster. Such efforts led to the identifica-tion of three distinct forms of Mediator complexes. Inexploring their compositional and functional heteroge-neity, we found that the smallest complex (C1) is highlyenriched in a certain type of Drosophilacells and pos-sesses novel Mediator proteins. The subonits staredamong the three Mediator complexes (C1, C2, and C3)appear to lorn a stable modular structure that serves asa binding surface for transcriptional activator proteins.However, only C2 and C3 were able to support activatedtranscriptioa in vitro. These findings suggest that dif-ferent cell types may require distinct Mediator com-plexes, bene of which may participate in nuclear pro-cesses other than the previousIy identified functions.
