This study deals zoning and building codes that act on the physical planning and design of university campus in Korea. Campus facility related laws were analyzed in relation to various factor found out through the survey on the existing campuses in rural or urban area. The study shows that the gaps between the standards required by the law and the state of facilitation in many universities could be filled by applying varied norms in accordance with the locational characteristics of each university.

In rock mass, great many discontinuity exists that is caused to various factors of formation. But these are parted to some groups by specific category, so called these as discontinuity set. This discontinuity set has unique special characteristics in original rock mass, but for the moment, differ the special quality if external force such as digging etc. acts, specially, change of stress condition. Also, geometrical relation change between discontinuity orientation and direction of excavation various characteristic is seen. Therefore, we introduce here the useful chart that can do specification these relation.

Purpose: The purpose of this study was to find out relation of general characteristics and memory performance of old adults. Method: The subjects consisted of 160 old adults over the age 60 who living in Seoul. Data were collected by the interview method, using a structured questionnaire and the testing method on the memory performance. Data were analyzed by SPSS PC. Result: The level of memory performance is 63.0 points in the 84 point scale, immediate recall is 7.8 points in the 12 point scale, delayed recall is 7.6 points in the 12 point scale, word recognition is 16 points in the 24 point scale, & face recognition is 16 points in the 24 point scale, & face recognition is 26.8 points in the 40 point scale. Analysis of memory performance according to general characteristics showed that there were statistically differences for age, sex, religion and alcohol. Memory performance showed a significantly negative correlation with age and alcohol, but positive correlation with sex. The significant variables to predict old adults'memory performance are age and alcohol. Conclusion: The findings of this study give useful information for constructing an memory performance improving program based on general characteristics in old adults.

Objectives : This paper aims to examine the Yin-Yang characteristics of bland taste. Methods : Medicinals including bland taste were searched in herbology textbooks and mainly in the Bencaogangmu, of which major discourses were analyzed to examine the Yin-Yang characteristics of bland taste. Results & Conclusions : Most medicinals with bland taste were sweet-bland-cold, holding properties of cooling heat, stimulating urination and detoxification. These properties could be explained in relation to the Triple Burner's metabolism of Qi and fluids, as they stimulate perspiration and urination, improving the flow of fluids which in turn supports production of Original Qi, by working on the TB's Qi circulation system. In the bland taste discourse, it was understood that bland taste moves the Qi system and produces fluids, by first ascending then descending. Zhudanxi and the Neijing have opposing views on whether bland taste is Yin or Yang, but both saw blandness to have both Yin and Yang qualities. Characteristics of the bland taste could be better understood in relation to the Triple Burner. The phrase 'bland is attached to sweet taste[淡附于甘]' refers to the likeliness between the two tastes in that bland taste has the Central Earth qualities, integrating others and concealing itself in its blandness, its taste unspecific, mild and unstimulating thus communicating the Qi within the entire Triple Burner from Upper to Middle to Lower, as does sweet taste.

The unstable characteristic values of communication signals along with the varying SNR (Signal Noise Ratio) environment make it difficult to identify the modulations of signals. Most of relevant literature revolves around signal recognition under stable SNR, and not applicable for signal recognition at varying SNR. To solve the problem, this research developed a novel communication signal recognition algorithm based on Holder coefficient and cloud theory. In this algorithm, the two-dimensional (2D) Holder coefficient characteristics of communication signals were firstly calculated, and then according to the distribution characteristics of Holder coefficient under varying SNR environment, the digital characteristics of cloud model such as expectation, entropy, and hyper entropy are calculated to constitute the three-dimensional (3D) digital cloud characteristics of Holder coefficient value, which aims to improve the recognition rate of the communication signals. Compared with traditional algorithms, the developed algorithm can describe the signals' features more accurately under varying SNR environment. The results from the numerical simulation show that the developed 3D feature extraction algorithm based on Holder coefficient cloud features performs better anti-noise ability, and the classifier based on interval gray relation theory can achieve a recognition rate up to 84.0%, even when the SNR varies from -17dB to -12dB.

이 연구에서는 해석학적 전류-전압 모델을 이용하여 DGMOSFET(Double Gate MOSFET)의 전송특성을 분석하였다. MOSFET의 게이트길이가 100nm이하로 작아지면 산화막두께가 1.5m이하로 작아져야만하고 채널의 도핑이 매우 증가하기 때문에 소자의 문턱전압변화, 누설전류의 증가 등 다양한 문제가 발생하게 된다 이러한 문제를 조사하기 위하여 해석학적 전류-전압 모델을 이용하여 소자의 크기를 변화시키면서 전류-전압특성을 조사하였다 소자의 크기를 변화시키면서 해석학적 전류-전압 모델의 타당성을 조사하였으며 온도 변화에 대한 특성도 비교 분석하였다. 게이트 전압이 2V에서 77K의 전류-전압 특성이 실온에서 보다 우수하다는 것을 알 수 있었다.

최근 한국에서는 세계적인 녹색기술을 맞아 향후 차세대 교통 시스템으로서 튜브 트레인 시스템의 본격적인 연구가 진행되고 있다. 한국 철도기술연구원(KRRI, Korea Railroad Research Institute)에서 튜브 트레인 시스템의 건설을 위한 목적으로 연구가 진행되고 있다. 본 논문에서는 기초연구의 일환으로 축대칭하며 긴 형상의 수송체가 가지는 다양한 튜브(터널) 내부의 압력, 막힘비율, 운행속도를 파라미터로 선정하여 전산해석을 수행하였다. 세부사항으로는 동일 형상의 운송체가 동일 운행속도를 가지고 일반적 압력의 개활지(오픈 시스템, 개활지 운행)를 운행할 때와, 다양한 환경(튜브 내 압력, 막힘비율, 운행속도)의 튜브 내부를 운행할 때에 대하여 튜브 트레인의 공력특성 연구를 수행하였다. 이를 통하여 다양한 운행속도-막힘비율 별로 개활지와 동일 에너지 효율 나오는 튜브 내 압력(P-D 관계)을 계산하였고, 막힘비율 증가에 따른 튜브 내 감압 정도(P-${\beta}$ 관계), 다양한 막힘비율-튜브 내 압력 별로 운행속도에 따른 전체 항력 양상(D-V 관계)을 보여 주었다. 그리고 개활지 운행시와 튜브 내부 운행시의 에너지 효율(주행저항)을 비교하였고, 튜브 내부 운행 시 트레인이 갖는 효율과 관계되는 충격파 발생의 임계속도(critical V-B 관계) 및 한계속도(V-P 관계)를 얻을 수 있었다. 이러한 연구의 결과는 튜브 시스템 설계 및 건설에 꼭 필요한 것이며 가이드라인을 제시했다.
