최근 HRI(Human-Robot Interaction) 분야에서는 손동작 인식을 이용하는 연구가 이루어지고 있다. 본 논문에서는 손 골격 이미지를 이용한 CRNN(Convolutional Recurrent Neural Network) 기반의 동적 손동작 인식시스템을 제안한다. 제안하는 시스템은 특징화된 손 골격 이미지를 사용하여 범용적인 인식 모델을 생성한다. 실험 결과, 학습 데이터 수집에 참여하지 않은 사람의 손동작 인식 실험에서 높은 인식 정확도를 보인다. Recently, research using hand gesture recognition has been conducted in HRI(Human-Robot Interaction). This paper proposed CRNN(Convolutional Recurrent Neural Network)-based dynamic hand gesture recognition using a skeleton hand image. The proposed system used a characterized skeleton hand image to produce the universal recognition model. The experiment shows high recognition accuracy in the hand gesture recognition experiment with people who did not participate in collecting training data.

오늘날 공연예술소비는 주요한 여가활동의 하나로 점차 자리를 잡아가고 있으며, 이에 따라 공연예술산업의 규모도 매년 증가하고 있다. 그러나 공연예술 소비자에 대한 연구는 국내외를 막론하고 미미한 실정으로 이에 대한 연구가 요구된다. 본 연구는 공연예술 중 연극 관람객의 전문화 수준에 따라 관람동기 측면의 차이를 고찰할 목적으로 하였다. 본 연구의 목적을 달성하기 위해 자기기입식 설문지를 개발한 후 부산광역시 소재 연극극장 관람객을 대상으로 자료를 수집 (유효 n= 337)하였으며, 기술 분석, 주성분분석, 일원량 분산분석을 실시하였다. 결과에 의하면 연극에 대한 전문화 수준에 따라 연극관람객의 관람 동기는 모든 측면(일상탈출 및 자아정립, 타인과의 교제 및 지식습득, 문화향유욕구충족)에서 통계적으로 유의한 차이가 있었으며, 전문화 수준이 높을수록 각 동기의 중요성 또한 높은 것으로 나타났다. 연구 결과가 가지는 이론적 실무적 시사점에 대해 논의하였다. Recently consumption of performing arts becomes a major leisure activity. Accordingly the market size of performing arts industry has increased year by year. However research on performing art consumer is the least investigated area internationally and domestically. The aim of this study was to fill this gap. In particular, this study was investigated the difference in motivations of play audiences segmented by the level of specialization on play. A self-administered questionnaire was developed to accomplish the study purpose. The sample of this study (n= 337) was drawn conveniently fro those who visited play theaters in Busan Metropolitan City. Descriptive statistics, PCA(Principal Component Analysis), and ANOVA(Analysis of Variance) with Scheffe post-hoc test were utilized. Results indicated that play audiences` motivations (escape and self identification, social relations and knowledge, and cultural desire fulfillment) were statistically different among the three groups segmented by the levels of specialization on play, Furthermore, the higher the levels of specialization on play, the greater the intensity of all motivations. Theoretical and practical implications were discussed.

We studied QTL(quantitative trait loci) influencing 2-year growths such as height increment, diameter at root collar, stem dry weight, root dry weight and total biomass of full-sib progenies between two selection clones, Odae 19 and Bonghyun 4 in Populus davidiana. Using 215 AFLP(amplified fragment length polymorphism) markers, we constructed 16 framework maps covering 545 cM with the average marker density of 12.8cM. CIM(composite interval mapping) showed that two Q_(Pd-Hti)(21.8 cM in map 8) and Q_(Pd-Root)(Pd-Root)(0.01 -4 cM in map 12), were predominantly associated with the traits. Q_(Pd-Hti) significantly accounted for 11.1 % of total phenotypic variation for height increment. Q_(Pd-Root), had a significant pleiotropic effect on diameter at root collar, root dry weight, primary root dry weight and total biomass dry weight explaining 11.6~12.3 % of their phenotypic variations. The two QTLs had no interaction between them, which indicates that they independently control the height increment and the other traits, respectively. Using the single marker analysis, we also identified two independent QTLs, named as QrGM59 and QrGM127, with relatively small effect on height increment, stem dry weight, fine root dry weight and total biomass dry weight. Q,.GM59 was significantly related with height increment explaining 5.3% of phenotypic variation and had no interaction with Q_(rGM59), Q_(rGM127) showed a weak interaction with Q_(Pd-Root) for stem dry weight and total biomass dry weight, and it accounted for 6.2% and 5.4% of the individual phenotypic variation, respectively. The dominant alleles at the four QTLs were inherited from the mother tree, clone Odae 19 which had already showed the best survival rate and good growth at poor planting site in the previous clone stability test. The results in this study indicate that the above- and below-ground growth of P. davidiana could be independently controlled by few genes, and that the QTL markers will be successfully used for selecting clones with good growth in both traits.
