This paper compares the combination performance of feature point-based matching algorithms as a study to confirm the matching possibility between image taken by a user and a virtual texture image with the goal of developing mobile-based real-time image positioning technology. The feature based matching algorithm includes process of extracting features, calculating descriptors, matching features from both images, and finally eliminating mismatched features. At this time, for matching algorithm combination, we combined the process of extracting features and the process of calculating descriptors in the same or different matching algorithm respectively. V-World 3D desktop was used for the virtual indoor texture image. Currently, V-World 3D desktop is reinforced with details such as vertical and horizontal protrusions and dents. In addition, levels with real image textures. Using this, we constructed dataset with virtual indoor texture data as a reference image, and real image shooting at the same location as a target image. After constructing dataset, matching success rate and matching processing time were measured, and based on this, matching algorithm combination was determined for matching real image with virtual image. In this study, based on the characteristics of each matching technique, the matching algorithm was combined and applied to the constructed dataset to confirm the applicability, and performance comparison was also performed when the rotation was additionally considered. As a result of study, it was confirmed that the combination of Scale Invariant Feature Transform (SIFT)'s feature and descriptor detection had the highest matching success rate, but matching processing time was longest. And in the case of Features from Accelerated Segment Test (FAST)'s feature detector and Oriented FAST and Rotated BRIEF (ORB)'s descriptor calculation, the matching success rate was similar to that of SIFT-SIFT combination, while matching processing time was short. Furthermore, in case of FAST-ORB, it was confirmed that the matching performance was superior even when 10° rotation was applied to the dataset. Therefore, it was confirmed that the matching algorithm of FAST-ORB combination could be suitable for matching between virtual texture image and real image.

이유진(Lee, Yoo Jin),안형준(Ahn, Hyung Jun) 한국예술경영학회 2016 예술경영연구 Vol.0 No.37

국내 뮤지컬은 2000년대 이후 질적, 양적 성장을 이루면서 국내 공연 문화 산업의 큰 축을 이루고 있다. 현재도 수입 라이선스 뮤지컬과 더불어 다양한 창작 뮤지컬이 매년 계속 제작되는 등, 지속적인 성장을 이어가고 있다. 이러한 중요성에도 불구하고 뮤지컬 분야에 대한 연구는 이제까지 그 주제 및 연구 방법 측면에서 제한적으로 이루어져왔고, 특히 사회연결망 분석 기법을 적용한 연구는 찾아보기 힘들다. 본 연구에서는 국내 뮤지컬을 대상으로 배우들이 구성하는 사회연결망을 분석함으로써, 그 특성, 주요한 배우들, 그리고 사회연결망의 지표가 배우들의 향후 활동에 끼치는 영향을 분석하고자 하였다. 2004년부터 9년간의 주요 뮤지컬에 출연한 221명의 배우들을 대상으로 한 분석 결과, 이정열, 민영기, 김법래 등 사회연결망에서 주요한 역할을 하는 배우들을 파악할 수 있었으며, 사회연결망의 지표들이 배우들의 활동을 단기 혹은 장기적으로 예측하는데 유용함을 밝혀내었다. 본 연구는 국내 뮤지컬에 대해 처음으로 사회연결망 분석 기법을 적용했다는 점에서, 그리고 종단적 분석을 통해 사회연결망 지표의 영향을 규명했다는 점에서 그 의의가 있다. Korean musicals have accomplished both qualitative and quantitative growth since 2000, constituting a major part of domestic performing arts industry. It has been continuing its growth until now with not just licensed musicals, but also a variety of original ones being produced each year. Despite its importance, studies on musicals have been limited both in its scope and research methods so far. Especially, it is hard to find any study in Korea applying the social network analysis method to musicals. In this study, by analyzing the structure of the social network of Korean musical actors, we aimed to identify the key characteristics and major actors of the network, and also to investigate the influence of its indices on the level of activities of the actors in the future. A total of 221 actors who appeared in the major musicals in the nine-year period from 2004 were targeted for the analysis. From the results, it was observed that the actors such as Jung Yeol Lee, Min Young Ki, and Pub Lae Kim are located at the most important positions in the network. It was also found that the degree and centrality measures of the network are useful for predicting the short-term and long-term activities of the actors. The contribution of this study lies in that it has applied the social network analysis to the musical actors in Korea for the first time, and also that it has identified the influence of the social network indices through a longitudinal analysis.

The purpose of this paper is find out the factor of the pleat patterns characteristics. This study was conducted to find out the characteristics of the 18 different pleat patterns. Sensory test was used to effectively conduct this task. The bases of the 18 pleat pattern were used to analyze the Verimax and the one-way Anova of the 24 items that are to be found out from our study. The results were concluded as below. 1. After analyzing 18 different pleat patterns we were able to extract 6 different factors, with factor loading value of 56.469%. These 6 different factors are ranking by the size of their factor loading values. The ranking predominantly used variables such as sensual emotional characteristics, the quality of the material, charity, profoundness, size, and simplicity. 2. Rather than having dot or strip print patterns, the pleat pattern turned out to be very abstract, hence the 6 factors share a different visual pattern. 3. When evaluating the relationship between the 6 factors and the 18 pleat pattern in terms of colors, rather than having a strang positive correlation, we can see a very contrasting negative correlation between the two. 4. After finding the difference in pleat pattern that consists in the 6 different factors. Statistics show that there exists a difference from the pleat patterns with a risk ratio of 1%.

본 연구는 10~24개월 영아의 월령에 따른 영아와 어머니의 의사소통의 발달변화를 살펴보고, 이들 간의 관계를 밝히고자 실시되었다. 연구결과, 첫째, 영아의 의사소통 기능 중 행동통제는 16~18개월까지 증가하였다가 감소한 반면, 주의환기는 16~18개월에 급증하여 지속적으로 증가하였다. 영아의 의사소통 수단 중에서는 몸짓이 가장 많이 산출되었으며, 몸짓, 몸짓+발성은 16~18개월에, 몸짓+단어, 단어는 19~21개월에, 단어, 단어조합은 22~24개월에 유의하게 증가하였다. 둘째, 어머니의 의사소통 기능 중 사회적 행위는 16~18개월을 기준으로 감소한 반면, 주의환기는 증가하였다. 어머니의 의사소통 수단 유형 중 몸짓+단어가 가장 많이 산출되었으며, 몸짓+발성과 몸짓은 16~18개월부터 감소한 반면, 단어조합과 단어는 증가하여 비슷한 수준을 유지하였다. 마지막으로 의사소통 기능면에서 영아의 주의환기는 어머니의 주의환기와 정적 상관을 보인반면, 사회적 행위와는 부적상관을 보였다. 의사소통 수단 면에서 영아의 몸짓, 몸짓+발성은 어머니의 몸짓+발성, 발성, 몸짓+단어와 영아의 몸짓+단어, 단어는 어머니의 단어, 단어조합과 정적상관을 보였다. This study was conducted to identify the relationship between infants' communication and mothers' communication. The objects of this study were 80 pairs of the infants aged 10 to 24 months and their mothers. Those were divided into five groups; 10-12 months, 13-15 months, 16-18 months. 19-21 months, and 22-24 months. The infants' and mothers' communication was observed during infant-mother free play for 10 minutes. The collected data were analyzed by one-way ANOVA and Pearson'scorrelation. The results of this study were as follows; First, behavior regulation of infants increased among 13-15 months and 16-18 months, and then decreased after that period. Joint attention rapidly increased among 16-18 months and continually increased until 22-24 months. For the communicative means of infants, gesture, and gesture and vocalization rapidly increased among 16-18 months, gesture and word, and word among 19-21 months, word and word combination among 22-24 months. The highest frequency of gesture during 10 to 24 months indicated its important role for infants' communication. Second, the social interactions of mothers decreased among the infants aged 16-18 months, while joint attention increased. The most frequently used one of communicative means was gesture and word. Third, behavior regulation and joint attention of the infants up to aged 16-18 months developed in proportion to the frequency of behavior regulation. The more word and word combination used by mothers, the higher frequency in gesture and word, and word of infants aged 19-21 months.

Objectives: The purpose of this study is to examine the effects of treatment with scalp acupunctures for children with learning disorders. Methods: For this study, we evaluated Korea standard progressive matrices test (K-SPM) on 24 children with learning disorders who visited Korean medical center neuropsychiatry outpatient clinic from July 2012 to January 2013. Scalp acupuncture, cognitive enhancement therapy and speech-language therapy were applied. All children were treated 2 times a week for 4 months and we compared K-SPM test scores before treatment and 30 times after the treatment. Results: 1) After the treatment, K-SPM test scores have increased significantly (p<0.05) and the number of children in grade 5 (<5%) have decreased from 14 to 6. 2) Comparing K-SPM test scores between two groups: one with medical history and the other without medical history, the scores in both groups have increased significantly (p<0.05). 3) We also divided the children into two groups according to age: under the age of 13 and over the age of 13, and compared K-SPM test scores. Although the scores in both groups have increased respectively, it is the scores of the former group (under the age of 13) that have increased significantly (p<0.05). Conclusions: The treatments with scalp acupunctures were shown to be an effective intervention when improving K-SPM test scores of children with learning disorders.

고감성 니트디자인을 위한 무봉제 니트 조직패턴의 성능과 이미지 간의 연구(2)

이유진(Yoo Jin Lee),최원정(Won Jung Choi) 한국디자인문화학회 2012 한국디자인문화학회지 Vol.18 No.2

본 연구에서는 소비자가 느끼는 무봉제 니트웨어의 착용감과 외관이미지 평가에 대해 알아보고 그 결과를 비교분석하여, 향후 무봉제 니트웨어의 고부가가치화를 높이고 디자인 개발에 있어 기초적인 소비자 반응을 예측할 수 있는 기초자료를 제공하고자 한다.연구방법으로는 12G 무봉제 니트 풀오버의 색상,편성조직, 마치의 종류에 따른 관능검사를 위하여 그조건을 다르게 한 18종류의 시료 36장을 사용하였다.실험은 국내 성인여성을 대상으로 하였으며, 착의평가(9종류-25명) 및 시각적 평가(18종류-50명)를 통해비교분석하여 다음과 같은 결론을 얻었다. 첫째, 착의평가의 경우 마치종류에 따라서는 착용감의 차이를 보이지 않았으나, 편성조직간 착용감에서는 팔을 앞으로 들어 올리는 동작의 경우에 유의한 차이를 보였다. 또한 3가지 편성조직 중 Plain을 착용했을 때 가장 편안한 착용감을 느낄 수 있다고 나타났다.따라서 착의평가는 편성조직이나 마치종류 이외에연령별 체형, 니트웨어의 중량감이나 두께감 등과 같이 좀 더 다각적인 면에 의해서 평가된다고 추측할수 있다. 둘째, 시각적 평가를 분석한 결과, 3가지 마치종류간에는 시각적 이미지 평가의 차이를 보이지않았다. 셋째, 편성조직간의 시각적 평가를 분석한 결과, 모든 시료에서 항목1(수수한-화려한), 3(무거운-가벼운), 4(부피감이 없는-있는), 5(거친-매끄러운)의 이미지는 편성조직에 큰 영향을 받은 것으로 나타났다. 넷째, 편성조직간의 시각적 평가를 사후검정하여 알아본 결과, 다음과 같은 편성조직간의 이미지 차이를 알게 되었다. 우선 18개 시료의 이미지에서 3가지 마치종류는 큰 영향을 미치지 않는 것으로 나타났다. 따라서 마치종류보다는 편성조직에 의해서 그 이미지가 형성되는 것으로 판단된다. Plain의 경우, 색상과 마치의 종류와는 관계없이 수수하고 매우 부드러우며, 가볍고 매끄러운 이미지가 강하였다. 또한 다소친근감이 있으며 여성적인 이미지로 평가되었다. Rib의 경우는 색상과 관계없이 화려하며 무겁고 부피감이 느껴지는 이미지로 평가되었다. Purl의 경우는 White 와 Black의 색상에 따라서 이미지가 다소 다르게 평가되었다. 다섯째, 편성조직과 마치종류가 동일한 시료간의 색상 이미지 평가에서는 3가지 편성조직 중Rib가 가장 많은 항목에서 색상간의 차이가 있었다. 이로써 색상간의 이미지는 같은 항목일 경우에도 편성조직에 의해서 색상의 이미지가 다를 수 있다는 것을 알 수 있다. The study aimed to examine the wearing sensation of seamless knitwears and the evaluated image of exterior, conduct comparison analysis of the results and provides a foundation on which the seamless knitwears` high added value can be enhanced and consumer`s basic response can be predicted. The research methods included 36 samples of 18 kinds of which the requirements have been varied for the sensory test on the colors of 12G seamless knitted pullover, structured knitted fabrics and different types of Machi. The study was conducted on female adults residing in Korea and the following results were obtained after conducting comparion analysis from the dress evaluation of 9 kinds on 25 subjects and visual evaluation of 18 kinds on 50 subjects. Firstly, the dress evaluation showed no difference on the types of Machi, whereas slight difference was found for structured knitted fabrics when arms were lifted upwards. Moreover, Plain was evaluated to be the most comfortable when worn among three structured knitted fabrics. Thus, aside from structured knitted fabrics and Machi types, the dress evaluation is considered to focus on multifaceted features such as the weight and thickness of knitwears. Secondly, the analysis of visual evaluation showed no significant change in evaluation of visual images on the three Machi types. Thirdly, regarding the analysis of visual evaluation for each structured knitted fabric, the images of category1 (plain-fancy), 3(heavy-light), 4(no volume-with volume), and 5(rough-smooth) for all samples had a great impact on structured knitted fabrics. Fourthly, post-hoc analysis on the visual evaluation for each structured knitted fabric showed the following image differences. The three types of Machi did not influence the images of 18 samples. Thus, the images were considered to be created by structured knitted fabrics rather than the types of Machi. For Plain, simple, soft, light and smooth images were dominant. Plain was also evaluated to have a friendly and feminine image regardless of colors and Machi types. For Rib, fancy, heavy and voluminous images were dominant regardless of colors. For Purl, each image was evaluated differently for White and Black. Lastly, the color image evaluation on samples with the same structured kitted fabrics and Machi types showed that among the three structured knitted fabrics, Rib showed color differences on the largest number of categories. This indicates that the color images may be different due to structured knitted fabrics even when the categories are the same.
