This study focused on the method of separation - space organization- as one of the architectural methods that is considered by the view point of its location and arrangement of 'Byoul-seo' private garden pavilion in Honam province. As a result, the followings are conclusions; By this study, they can be found in the concept of '居敬窮理', '格物致知'. It is presumed that nature union is archived through the 'yan-sang(玩賞)' which is ultimate state of knowledge that is based on the premises of opened significance in emancipation from narrow view point in the past and cognition of value. Therefore, it is needed to know the unworldly point of space perception about the pavilion territory, furthermore to have conceptual method to distinct pavilion from the world. there are two methods in the distinct concept in this pavilion research: unworldly separation and meditative separation. It is concluded that the specific consideration of the method of separation that is applied in the Byoul-seo pavilion. And it is accomplished by the contemplation of separation method in approach and entrance of direct influence area. they could be 1) cross the hill, 2) cross over a brook, 3) lifted up in the mount, 4) penetrate the forest, and 5) narrow entrance, which could be part of location.

Common finch is a kind of ornamental birds and could not distinguish male and female birds. For sex discrimination of Common finch, we investigated 400 birds of Common finch using the anatomical differences of Pars intermandibularis and traditional methods that currently used at the farms. Both methods have the sex determination accuracy of 48.82 and 46.0 ％ that the anatomical difference method seems little higher results than the traditional methods. More researches is needed for improving the sex determination accuracy.

This paper propose an algorithm for preprocessing of character recognition, which classify characters into Hangeul and Hanja. In this study, we use the 9 structural chacteristics of Hanja which isn't affected by deformation of size and style of characters and rates based on character size to classify characters. Firstly, we process the blocking to segment each characters. Secondly, on this segmented characters, we apply algorithm proposed in this paper to classify Hangeul and Hanja. Finally, we classify characters into Hangeul and Hanja, respectively. An experiment with 2350 Hangeul and 4888 Hanja printed Gothic and Mincho style of KS-C 5601 are carried out. We experiment on typeface sample book, newspapers, academic society's papers, magazines, textbooks and documents written out word processor to obtain the classifying rates of 98.8%, 92%, 96%, 98% and 98%, respectively.

Precise and rapid method out for distinguishing blended sesame oils through the electronic nose analysis was developed. Sesame oil was blended with corn oil at the ratio of 95 : 5, 90: 10, and 80 : 20 (w/w), respectively. Samples were then analyzed by gas chromatography, SPME-GC/MS, and the electronic nose composed of 12 different metal oxide sensors. Sensitivities $(delta\;R_{gas}/R_{air})$ of sensors from electronic nose were analyzed by principal component analysis (PCA). Proportion of the first principal component was 98.76%.

The Feather Color of chicken is considered as most obvious, and the purpose of this study is to identify the genotype following the SNP of MC1R, MITF and TYRP1, which are genes related to Feather Color, and develop a SNP marker that can be classified per breed. When a haplotype is observed through the combination of markers, a Korean Native Chicken can especially be distinguished when it is a CGG type in the SNP combination of the MC1R gene. In case of the TAG, TGG and TAA types, only Araucana was identified, and for the CAA type, Leghorn could specifically be distinguished. In the SNP combination of TYRP1 gene, only Leghorn was differentiated in case of the TTTCA and CCTCA types, and only Silky Fowl was identified in case of the CTTTA type. The SNP combination of MC1R gene enabled for Korean Native Chicken, Leghorn, and Araucana to be distinguished and each of the SNP and combination of TYRP1 gene allowed for all 4 breeds to be classified. If many researches are conducted about genetic polymorphism between breeds, then it is considered that the differences between breeds will be understood from a molecular biological aspect instead of simply distinguishing the breeds through Feather Color.

Sudoku is a famous Latin-square-based number-placement puzzle. Mo and Xu (2008) proposed Sudoku square designs based on the idea of Sudoku. Using several Sudoku square designs which are mutually orthogonal, we can suggest the orthogonal Sudoku square designs with block effect discrimination.

본 연구에서는 질문지법을 이용하여 과학기술분야 연구자들의 정보요구를 파악하고 이를 바탕으로 정보요구별 탐색행태를 분석하였다. 분석결과, 특정 정보요구에 대해 비공식 커뮤니케이션 채널이 정보탐색에 중요한 영향을 미치는 것으로 나타났으며, 탐색과정에서 이용자가 느끼는 정보부족의 원인에 대해서는 정보요구별로 어느 정도 차이가 있는 것이 확인되었다. 반면, 정보탐색환경에서 연구자들이 중요하게 생각하는 요소는 정보요구별로 큰 차이가 없는 것으로 나타났다. 정보요구를 바탕으로 과학기술분야 연구자의 탐색행태 분석결과를 적용함으로써 이용자 특성에 따라 개별화된 과학기술 정보 서비스를 기대할 수 있다.

This paper discusses a fitness of the control on intersection using fuzzy analytic hierachy process. The validity of control of traffic signal on intersection is the fitness of phase and cycle on the intersection. The validity of the controller is cleared by the comparison of the delay time of vehicle. Fuzzy analytic hierachy process clears the grade of validity of the fixed cycle time controller and adaptive fixed cycle time and fuzzy trafic controller and proposes a new control type a traffic signal by this fuzzy analytic hierachy process.

최근 스마트 수도미터의 보급을 통해 수용가구별 물 사용 자료를 수집할 수 있다. 이런 수용가구별 물 사용 패턴은 주말, 날씨 등 다양한 요인으로 인해 비선형적 특성을 가지고 있다. 그로인해 전통적인 시계열 예측 모형인 ARIMA 모형으로 적용하기 어렵다. 따라서 본 연구에서는 딥러닝 기반의 LSTM 모형을 통해 수용가구별 물 소비량 예측 모형을 개발하였다. 이 모형은 비선형적인 물 소비 패턴을 학습하기 위해 다양한 변수를 고려하였다. 서로 다른 종류의 4개 type (A : 단독주택, B: 아파트, C: 음식점, D : 초등학교)의 수용가구에 대한 ARIMA 모형과 LSTM 모형을 개발하였고, 학습에 사용되지 않은 새로운 데이터를 적용하여 정량적으로 예측성능을 비교했다. 그 결과, 모든 수용가구에서 LSTM 모형이 ARIMA 모형보다 성능이 우수하였다 (상관계수 : 평균89% | RMSE : 평균 5.60m³). 따라서 본 연구에서 제안한 모형은 수용가구별 물 사용량을 예측하는데 높은 활용도를 보일 것으로 기대된다.
