Daily dance Ganggangsullae is recommended for youth to help their diet, improve their team life and know Korean culture. Its performance costumes were fusion hanbok and casual wear shown at the Second Daily Dance Ganggangsullae Contest Conference of Myeongryang Battle Festival in 2013. A fusion hanbok shows the Korean traditional spirit, but it is not practical. Casual wear is practical, but it does not show any Korean identity. Therefore, their combination is needed to reflect the Korean identity and practicality. For this, a literature review and an online search were conducted for the history, purpose and dance motion of daily dance Ganggangsullae. And photographs of participating teams were gathered from Jeonnam Information & Culture Industry Promotion Agency. Goguryeo costumes were used for design motifs. Four designs were sets of T-shirts and pants for the summer. Style 1 is designed using sam, jikryeong, go, round and triangle pattern with rippled cotton. Colors were from Wang Huiji's mural painting. Style 2 is designed using dansuui, beonryeong, go, round and quadrangle patterns with rippled cotton. Colors were from a Deokheungri mural painting. Style 3 is designed using sam, round ryeong, go, quadrangle patterns, prints with cotton jersey and denim. Colors were from a Gamsinchong mural painting. Style 4 is designed using dansuui, jikryeong, go, a flame pattern, a bow and arrow shape with cotton, knit and jersey. Colors were from a Muyongchong mural painting. This study is helpful to anyone who wants to develop Korean-style performance costumes.

남서부 영남육괴 안의도폭 지역의 변형 화강암류에 대한 SHRIMP U-Pb 연대측정을 수행하였다. 선캠브리아 편마암으로 알려진, 현저하게 변형된 호상구조를 보이는 압쇄조직의 화강암과 비교적 약하게 변형된 반상 내지 안구상의 화강암 각각 한 개씩의 시료에서 분리된 저어콘에 대한 연대측정 결과는 약 195 Ma로 연대가 동일하였다. 이 연구 결과와 기존의 연대자료에 의해 안의도폭 주변부 지역에서의 중생대 초-중기 화성활동은 다음과 같이 해석되었다: 트라이아스 중기(약 225-219 Ma)에 섭입관련 화강암질 마그마작용이 주로 서부지역에서 함양 화강암의 관입으로 시작되었고 트라이아스 말기(약 220-210 Ma)에 섬장암질 관입으로 끝났다. 비교적 짧은 휴지기 후에, 쥬라기 초기인 약 195 Ma에 이번 연구에서 연대가 측정된 변형 화강암류를 생성한 마그마의 관입으로 화강암질 마그마작용이 다시 시작되어 약 189 Ma까지 계속되었으며, 화강암질 마그마작용의 말기에는 섬록암류의 관입이 수반되었다.

The Eunsan gold mine, together with similar nearby prospects, is situated near the centre of the ‘Wusuyeong’ 1:50000 Scale Geological Quadrangle, an area largely underlain by a thick sequence of non-marine Cretaceous strata. The sequence, several kilometres thick, comprises basaltic and andesitic lavas and tuffs, intercalated with fluvial and lacustrine sediments, passing upwards into a further thick volcanic sequence of predominantly dacitic and rhyolitic composition.

본 논문에서는 SVM(Support Vector Machine)과 LDA(Linear Discriminant Analysis)를 이용하여 사각형 형태 마커 검출 및 인식의 성능을 향상시키는 방법을 제안한다. 본 논문의 방법에서는 사각형 형태의 마커 검출을 위하여 입력 영상을 이진 영상으로 변환하고 객체들의 윤곽선을 추출한 다음에 윤곽선을 선분으로 근사화 한다. 근사화된 선분으로부터 기하학적 특징을 이용하여 사각형을 찾는다. 마커의 사각형 영역을 찾은 다음에는 워핑 기법과 확대/축소 변환을 이용하여 사각형 영상을 정사각형 형태로 정규화한다. 정사각형 형태로 정규화한 다음에는 주성분 분석을 적용하여 특징 벡터의 크기를 줄인 다음에 SVM을 이용하여 마커 영상인지 아닌지를 검사한다. 마커 영상으로 판별된 영상에 대하여 LDA를 적용하여 특징 벡터의 크기를 더 줄이고 표준 마커에 대한 특징 벡터와의 최소 거리법에 의해 마커의 종류를 인식한다. 인식 실험 결과 SVM을 사용함으로써 마커 검출의 오류를 줄일 수 있었고 LDA를 사용함으로써 특징 벡터의 크기는 줄어들고 인식률이 높아짐을 알 수 있었다.

We evaluate what kinds of differences are existed to the visual sensitivity of college students m Daegu and Daejeon. Evaluation used the produced basic pattern to change modeling element of figure, direction, proportion, and color. The results are as below. The circle is preferred to the figure sensitivity and the triangle in Daegu and triangle and quadrangle in Daejeon is disliked. The direction sensitivity shows the difference of preferences according to figure. The angle of $0^{\circ}$ and $90^{\circ}$ which could be felt stability is preferred in general. In proportion sensitivity, the basic figure 1:1 rectangular proportions are preferred. The color sensitivity I shows the differences of preference according to figure and there are difference to the area in the degree of aversion.

This study surveys the surface water environment in Southwest sea areas of Vietnam in order to evaluate the current environment. It collects and analyzes experimental results of programs, scientific subjects, and international projects relevant to ecological areas and coastlines of Kien Giang province. The methods analyzed and discussed by specialists are evaluated according to pollution coefficients established by the World Health Organization (WHO), sampling methods, and case study analyses. Comparison between the scale of pollution levels and the surface water quality in experimental areas of Long Xuyen Quadrangle shows a light-moderate pollution level. In Ca Mau Peninsula, the surface water source is only slightly polluted. Sea areas and islands are also light-moderately polluted. Computing results from water quality indices (WQI) show the level of pollution in experimental sites. Activities such as constructing infrastructures for tourism, exploiting minerals, and increasing population accelerate environmental pollution by deteriorating inherently sensitive ecosystems like corals, sea grass, mangrove swamps, and Melaleuca forests. Surveying and evaluating the present situation of surface water are fundamental solutions for environmental protection in the Southwest sea areas of Vietnam.

Selective laser sintering is a kind of rapid prototyping process whereby a three-dimensional part is built layer wise by laser scanning the powder. This process is highly influenced by powder and laser parameters such as laser power, scan rate, fill spacing and layer thickness. Therefore a study on fabricating Fe-Ni-Cr powder by selective laser sintering has been performed. In this study, fabrication was performed by experimental facilities consisting of a 200W fiber laser which can be focused to 0.08mm and atmospheric chamber which can control atmospheric pressure with argon. With power increase or energy density decrease, line width was decreased and line surface quality was improved with energy density increase. Surface quality of quadrangle structure was improved with fill spacing optimization.

In this paper, nonlinear nonplanar vibration of a flexible rectangular cantilever beam is analyzed when one-to-one resonance occurs to the beam. The planar and nonplanar motions of the beam are analyzed in time and frequency domains. In frequency domain, FFT analyzer is used to perform autospectrum and cepstrum analyses for nonlinear response of the beam. In time domain, an oscilloscope is used to investigate the phase difference between the planar and nonplanar motions and to perform Torus analysis in the phase space. Through those analyzing process, the main frequencies of superharmonic, subharmonic, and super-subharmonic motions are investigated in the nonplanar motion due to one-to-one resonance. Analyzing the phase difference between the planar and nonplanar motions, it is observed that the phase difference varies in time.

During the navigation of mobile robot, one of the essential task is to determination the absolute location of mobile robot. In this paper, we proposed a method to determine the position of the camera from a landmark through the visual image of a quadrangle typed landmark using neural network. In determining the position of the camera on the world coordinate, there is difference between real value and calculated value because of uncertainty in pixels, incorrect camera calibration and lens distortion etc. This paper describes the solution of the above problem using BPN(Back Propagation Network). The experimental results show the superiority of the proposed method in comparison to conventional method in the performance of determining camera position.

In this paper, we propose a method fur measuring the dimensions of an arbitrary object using geometric relationship between a perspective projection image and a rectangular parallelepiped model. For recognizing the vertexes of the rectangular parallelepiped surrounding an arbitrary object, the method adopts a strategy that derives the equations for vertex recognition from the geometrical relationships for image formation between 2D image and the rectangular parallelepiped model. extracts from 2D image with vertical view features (or junctions) of minimum quadrangle circumscribing an arbitrary shape object, and then recognizes vertexes from the features with the equations. Finally, the dimensions of the object are calculated from these results of vertex recognition. By the experimental results, it is demonstrated that this method is very effective to recognize the vertexes of the arbitrary objects.
