강구조물은 도장에 의한 방식법을 적용하고 있으며 염분 및 자외선 등과 같은 여러 요인에 의하여 노화가 진행된다. 도장의 경우 대기 부식 환경하의 도막열화로 인하여 그 수명이 제한되므로 공용기간 동안 지속적이며 반복적인 재도장이 진행된다. 도장을 통하여 부식에 대한 강구조물의 내구성능을 확보하는 탄소강은 도막열화로 인하여 그 수명이 제한되므로 무도장 상태일 경우의 부식저항성능을 검토할 필요가 있다. 본 연구에서는 부식촉진실험을 통한 무도장 강재의 부식속도와 ISO 9223의 부식환경별 부식속도의 비교를 통하여 촉진배율을 제안하고자 한다.

전강영신(田岡永信) 선사는 조사선(祖師禪) 전통을 계승하고 발전시킴으로써 한국 불교 선사상(禪思想)의 명맥을 이어나간 대표적인 조사(祖師)이다. 전강영신 선사는 간화선(看話禪) 참구법(參究法)을 통하여 깨달음을 증득하였고, 이를 통하여 자신만의 선사상을 정립하였다. 그의 간화선은 전통적 간화선을 바탕으로 함과 동시에 자신만의 수행법과 지도방식을 추구함으로써 독자적인 선사상을 주창하였다. 이와 같은 전강영신 선사의 선사상을 살펴보기 위하여 그의 사상이 축약 되어 있는 법어집 『언하대오(言下大悟)』를 바탕으로 그가 제시한 화두수행의 참구법을 살펴보고자 한다. 전강영신 선사는 그의 구도, 교화 과정에서 드러나는 수행방식을 통하여 전통적인 한국 불교 선사상에서 볼 수 없었던 선사의 선사상에 나타나는 독자성, 정체성을 확립하였다. 전강영신의 선사상은 그의 법어집인 『언하대오』에 잘 드러나 있다. 법어집의 제목을 『언하대오』라고 붙인 것에서 알 수 있는 바와 같이 그의 법어집에는 그가 보여주고자 하는 사상의 모습이 잘 드러나 있다. 총 7장으로 구성되어 있는 법어집에서 선사는 마지막 장인 ‘화두 드는 법’을 제외한 목차에서 여러 가지 법담을 통해서 선사상의 면모를 유감없이 드러내주고 있다. 전강영신의 선사상을 이해하기 위하여 『언하대오』에 나타난 선사의 화두 참구법과 선문답을 분석하고자 한다. 그 중에서 가장 많이 언급되었고, 전강영신 선사가 주요하게 생각한 판치생모 화두 참구법과 무자화두 참구법의 특징을 중점적으로 살펴보고자 한다. 또한 선사가 화두 참구를 수행하면서 어떠한 마음 자세를 갖춰야 하는가에 대하여 설명하는 부분을 통하여 그의 선사상을 이해하고자 한다. 이러한 전강영신 선사의 선사상은 현대 한국 간화선의 방향과 정체성 정립에 중추적 역할을 한다 The Seon Master Jeonkangyeongsin (田岡永信) is a spiritual patriarch (祖師) who succeeded in the discipline of patriarchal meditation (祖師禪) and developed the tradition of Korean Seon Buddhism, continuing the Seon-thought (禪思想) of Korean Buddhism. The Seon Master Jeonkangyeongsin (田岡永信) acquired awakening (覺) through the Kanhwa-seon (看話禪) Investigation (參究) method and established his own thinkings on Seon. His Kanhwa-seon was based on the traditional Kanhwa-seon, and at the same time, he advocated for the independent self Seon thought by pursuing his own method of discipline and instruction. In order to examine the self Seon thought of Seon Master Jeonkangyeongsin, this paper, through his the tribute book of Dharma (法語集) 『Eonhadaeo (言下大悟)』, intends to look at the method of practicing the topic that he suggested, based on the abbreviation of his thoughts. Seon Master Jeonkangyeongsin established the identity that appeared in his Seon-thought, which was not seen in the traditional Korean Buddhist Seon-thought, through his composition and the method of practice revealed in the process of edification. The Seon-thought of Jeonkangyeongsin is clearly revealed in the 『Eonhadaeo』. As can be seen from the title of the tribute book of Dharma; what he wants to show is revealed in the book. The book which consists of a total of 7 chapters, the Seon Master reveals the aspects of the Seon Master through various teachings of the illustrious Dharma (法談) in the table of contents except for the last chapter. In order to understand the Seon-thought of Jeonkangyeongsin, this paper aims to analyze the Hwadu-Investigation (話頭參究) and Seon dialogue (禪問答) of spiritual patriarch in 『Eonhadaeo』. In particular focusing on the characteristics of the panchisaengmo (板齒生毛)-Hwadu investigation (參究) method and the non letter investigation Hwadu (無字話頭) method, which were mentioned the most, and that Seon Master Jeonkangyeongsin considered the main points. This paper would like to understand his thought of a Seon master through the section that explains what kind of attitude he should have while practicing. The Seon-thought of Seon Master Jeonkangyeongsin plays a pivotal role in establishing the direction and identity of the modern Korean Kanhwa-seon
POSITIVE SCHEME NUMERICAL SIMULATION OF HIGH MACH NUMBER ASTROPHYSICAL JETS

High Mach number astrophysical jets are simulated using a positive scheme, and are compared with WENO-LF simulations. A version of the positive scheme has allowed us to simulate astrophysical jets with radiative cooling up to Mach number 270 with respect to the heavy jet gas, a factor of two times higher than the maximum Mach number attained with the WENO schemes and ten times higher than with CLAWPACK. Such high Mach numbers occur in many settings in astrophysical flows, so it is important to develop a scheme that can simulate at these Mach numbers.

The Oriental mayfly, Ephemera orientalisMcLachlan, 1875 (Ephemeroptera: Ephemeridae), can be a promising candidate used for monitoring environ-mental risk in aquatic ecosystem. Its quite large distri-its genetic variability due to local selection and adap-tation according to environmental hazard gradient. Before addressing the hypothesis, we needed to havepolymorphic loci to discriminate individuals and cha-racterize a specific population. For this reason, mito-chondrial cytochrome oxidase-I subunit (mtCO-I) was chosen because of its relatively high mutational rate among mitochondrial genome. Two regional E. ori-entalis populations were obtained at Andong andHoengseong, where few industrial complexes werelocated and could be regarded as being conserved in genetic variability. The amplified product showed550bp in all tested samples and digested with Alu I andRsa I. Alu I cuts one site in wild type (major), buttwo sites in variants. Rsa I cuts one site in both wild and variant samples, but difered in position of the restriction site. With these markers, Andong and Hoeng-seong populations recorded variant ratios of 1.7% and 30.0%, respectively. However, wide-regional sampleand Russia did not show any variant types in thisanalysis, probably due to quite small numbers of sam-ples (one or two) in each location. In highly poly-morphic Hoengseong population, thorax morphological characters reflected the restriction site polymorphism.

<P>A compact 3-D stacked type waveguide structure is proposed for supporting the modern communication systems in the L-band frequency (700-900 MHz). The proposed structure can achieve very small size in comparison with a standard metal cavity filter designed at 900 MHz center frequency with a 3% fractional bandwidth. The design for this filter was developed with the High Frequency Structural Simulator (HFSS) and a Direct coupled Waveguide Filter Design (DWFD) program based on the direct coupled filter of λ/2 line impedance prototypes. This waveguide filter was designed by 8 poles with bandwidth 27.8 MHz at the center frequency 881 MHz with a ceramic material (εr=35.4). The measured result was in good agreement with the simulated responses and confirmed the accuracy of the design method.</P>
