옥천변성대의 북동 선단부에 위치하는 충청북도 제천시 봉화재 지역은 옥천누층군과 조선누층군이 분포한다. 본 논문은 중첩 변형된 주요 암석 및 미구조의 기하학적 운동학적 특성과 선후관계로부터 봉화재 지역의 지질구조를 연구하였다. 광역엽리의 대부분은 S0 층리가 아닌 신장된 광물들의 정향배열에 의해 정의되는 S0-1의 복합엽리로 나타나고, 일부는 불용해성 불투명 광물과 벽개 라멜라의 정향배열로 정의되는 S0-1-2 복합엽리로 인지된다. 연구지역의 지질구조는 북북동-남남서 방향의 D1 압축작용, 동-서 방향의 D2 압축작용, 남-북 방향의 D3 압축작용 등 적어도 세 번의 변형단계를 거쳐 형성되었다. 조선누층군과 옥천누층군 구성지층의 대상 분포방향과 유사한 S0-1 복합엽리는 D2 변형 이전에 서북서 방향이었으나, D2 변형에 의해 S2 엽리와 평행한 남-북 방향으로 재배열되었고, D3 변형에 의해 현재와 같이 북서, 북동, 남-북 방향으로 재배열되었다. 변형단계별 구조적 특성과 변형작용사는 연구지역의 조선누층군과 옥천누층군이 북북서 방향으로 연장되는 부산지역 동부 영역과 매우 유사하고, 이들 연구결과는 옥천변성대 북동 선단부의 지구조 발달과정을 해석하는데 매우 유용하게 활용될 것으로 기대된다.

영남육괴 지리산지구의 남동부에 위치하는 화개지역은 주로 선캠브리아기 지리산 변성암복합체로 구성되어 있으며, 선캠브리아기 구성암류는 남-북 방향의 밀착습곡과 동-서 방향의 개방습곡 형태의 암상분포를 보인다. 이 논문에서는 하동 회장암복합체의 서부에 위치하는 화개지역에서 지리산 변성암복합체의 변형된 암석구조에 대한 운동학적 기하학적 특징과 중첩된 변형구조들의 선후관계로부터 연구지역의 지질구조를 연구하였다. 그 결과, 연구지역의 지질구조는 적어도 세 번의 연성 변형단계를 거쳐 형성되었음을 알게 되었다. (1) $D_1$ 변형과 관련된 구조요소는 대부분 $D_2$ 변형에 의해 전위되어 $S_{0-1-2}$ 복합엽리로 인지된다. (2) $D_2$ 변형은 동-서 방향의 압축 지구조환경 하에서 남-북 방향의 $F_2$ 습곡과 $F_2$ 습곡축면에 (준)평행하게 발달하는 $D_2$ 연성전단대를 형성시켰다. (3) $D_3$ 변형은 남-북 방향의 압축 지구조환경 하에서 발생하여 그 이전 형성된 구조요소들의 방향성을 국부적으로 동북동 내지 서북서 방향으로 재배열시켰다. 이는 선캠브리아기 구성암류의 광역적인 남-북 방향의 밀착습곡과 동-서 방향의 개방습곡 형태의 암상분포는 각각 $D_2$ 변형, $D_3$ 변형과 밀접한 관련이 있음을 의미한다.

We propose a bicycle detection system riding on people based on modified projected local binary pattern(PLBP) for vision based intelligent vehicles. Projection method has robustness for rotation invariant and reducing dimensionality for original image. The features of Local binary pattern(LBP) are fast to compute and simple to implement for object recognition and texture classification area. Moreover, We use uniform pattern to remove the noise. This paper suggests that modified LBP method and projection vector having different weighting values according to the local shape and area in the image. Also our system maintains the simplicity of evaluation of traditional formulation while being more discriminative. Our experimental results show that a bicycle and motorcycle riding on people detection system based on proposed PLBP features achieve higher detection accuracy rate than traditional features.

The Purpose of this study is to investigate the jeogori included in the buddist statue in 1748. The jeogori was similar in shape to excavated costume of Andong Kwon, Papyung Yoon, and Chungyeongunju in 18th century. This jeogori was useful to estimate the interesting process of shape change of jeogori in 18th century. Four different silk fabrics were used in the jeogori. Outer fabrics were satin weave with floral, lattice strip, dragon, and cloud patterns. The ground area was 5-harness warp faced satin and the patterned area was 5-harness filling faced satin. An inner fabric was simple plain weave. Warp and filling yarns of all fabrics in this jeogori had no twist.

In this article, we present some derived subjects from the concept of ICT-based DPD concept for the safety of folk villages in both Korea and Japan. First, our deduced topic would rather be a monitoring system design of structures in folk villages. We, therefore, offer an integrated model of maintenance and management monitoring scheme. As another research subject, we submit safety sign or sign system installed in traditional towns and their standardization. We have draw up a plan to make signs upgrade applied to folk villages in Korea and Japan. According to our investigations, we should suggest and focus on flood in the area of traditional town in Korea. We present a water-level expectation model using deep learning simulation. We have applied this method to the area of 'Andong Hahoe' village which had been registered on World Cultural Heritage of UNESCO. The final goal of our research is to propose and realize an integrated disaster prevention and/or safety system based on big data concepts for both Korea and Japan.

For the purpose of investigating the impulsive noise at the exit of high-speed railway tunnel and the pressure transients inside the tunnel, experiments were carried out using a shock tube with an open end. A great deal of experimental data were obtained and explored to analyze the peak pressures and maximum pressure gradients in the pressure waves. The effects of the distance and cross-sectional area ratio between two-continuous tunnels on the characteristics of the pressure waves were investigated. The peak pressure inside the second tunnel decreases for the distance and cross-sectional area ratio between two tunnels to increase. Also the peak pressure and maximum pressure gradient of the pressure wave inside the second tunnel increase as the maximum pressure gradient of initial compression wave increases.

The sacrificial foods using at 88 villages in Andong area where the village sacrificial rituals are performed, were investigated in 1994. The finding are as follows; 1. Since the village sacrificial rituals keep ancientry, white Baeksulki without any ingredients is used as Ddock (a steamed rice cake) in 74 villages, and in 5 villages the Baeksulki was served just in Siru (a tool used to prepare Ddock). The type of meat serving in rituals has been changing from large animal to small animal and the type of light from bowl-light to candle. 2. Though the ritual observes Confucianism style, memorial address was offered in 34 villages and only in 8 villages, liquor was served 3 times and the address was offered. In 60 villages, liquor was served only once, and calling village god, bowing twice, and burning memorial address paper were performed in order. Burning paper has been meaningful in rituals. 3. Tang (a stew) was served in 21 villages, and in 18 villages even Gook (a soup) was not used. The numbers of village which do not use cooked rice and Ddock are 14, respectively. 4. Fruits are essential in rituals foods. In 63 villages, 3 kinds of fruits are served and this is contrasted with even number of fruits in Bul-Chun-Wi Rituals. 5. In 25 villages, fish and meat are not served. As meat, chicken in 19 village are served. Meat Sikhae (a fermented rice beverage) prepared with meats or fish are served in 5 villages. Slice of dried meat is served in 73 villages commonly. 6. In gender of god for village shrine, woman in 43 villages, couple in 17 villages, man in 9 villages, mountain god in 2 villages, villages tree, etc were enshrined. In 52 villages liquor is served in rituals (liquor is used in 58 villages including serving god), in 28 villages sweet liquor (Gamju) is served for god (sweet liquor is used in 46 villages), and liquor, water, or sweet liquor is just displayed on table but not served in 8 villages. Incensing is found to be not common in village ritual, only in two villages it is performed. The most appropriate rituals food is thought to be pig for mountain god. Home dishes can not be used in village ritual and spoon is not used and chopstick is prepared from wild plant. Meat and fish are used in the raw.

A computer simulation was carried out to determinate the optimum capacity of bulk type trailer which is used as a tractor attachment. Soil physical properties. such as soil moisture content. bulk density, soil hardness and soil texture were measured in the 10 major rice production area for computer simulation. Mathematical model which include soil physical properties and vehicle factor was used for computer simulation. Most of the soil texture of the investigated area was silty loam. Soil moisture content ranged between 30 and 40% mostly. Soil bulk density was in the range of 1.500 to 1.700 kg/㎥. Soil hardness ranged between 1 to 18 kg/$\textrm{cm}^2$. Soil hardness incorporate the effects of many soil physical properties such as moisture content texture and bulk density, and so the range of soil hardness was greater than any other physical properties. The capacity of bulk type trailer was above 3000 kg$_{f}$ fer the most of the investigated area. and mostly in the range of 4000 to 6000 kg$_{f}$ depending upon the slip. But for the soft soil area such as Andong and Namyang. tractor itself had mobility problem and showed minus trailer capacity for some places. For this area. the capacity of bulk type trailer ranged between 1000 and 2000 kg$_{f}$ mostly so bulk type trailer should be designed as a small capacity compared to the other area.ared to the other area. area.
