  • 비디오 하이라이트(highlights)는 원래의 비디오 보다 짧고 많은 양의 의미를 갖는다. 기존의 파노라마 형태의 추상화 기법은 여러 프레임을 하나의 프레임으로 모자이크하는 형태이었고, TV 드라마 하이라이트 방법은 카메라의 이동이나 특수효과에 의존하기 때문에 스포츠 비디오에 적용은 부적합하다. 이 논문에서는 축구 비디오를 대상으로 시각정보와 자막을 이용하는 새로운 비디오 하이라이트 생성 방법과 이벤트 기반 비디오 인덱싱 방법을 제안한다. 하이라이트 생성은 하이라이트 생성 규칙에 따라 자막에 의해 추출된 TIT을 중심으로 시각정보에 의해 추출된 샷을 합성하여 생성하였고, 인덱싱은 자막으로 추출된 샷은 주요소로, 시각정보에 의해 추출된 샷은 부가적 요소로 구성하였다. 실험에서는 샷 추출기법 중 대표적인 컬러히스토그램과 $\chi$$^2$히스토그램과의 성능을 비교하여 제안한 하이라이트 기법이 다른 방식보다 우수함을 증명하였다.

  • The displacement current measuring system used for detecting the dynamic behavior of monolayers at the air-water interface is described. It basically consists of a film balance, a pair of electrodes connected to each other through a sensitive ammeter. Here, one electrode is suspended in air and the other electrode is the water, With Maxwll-displacement-current-measuring method, the phase transitions of Poly(λ-benzyl- L-glutamate)(PBLG) on a water surface were detected, Displacement currents generated during the compression of monolayers of PBLG on the surface of water were investigated. As results, the displacement pick was generated when the area per molecule was about 15 $\AA$$^{2}$ in low pressure, and tit was generarted when the area per molecule about 27$\AA$$^{2}$ in high pressure.

  • In this study, an equivalent domain integral (EDI) method is presented to estimate the track-till integral parameter, J-value, for two dimensional cracked elastic bodies which may quantify the severity of the crack-tit) stress fields. The conventional J-integral method based on line integral has been converted to equivalent area or domain integrals by using the divergence theorem. It is noted that the EDI method is very attractive because all the quantities necessary for computation of the domain integrals are readily available in a finite element analysis. The details and its implementation are extened to both h-version finite element model with 8-node isoparametric element and p-version finite element model with high order hierarchic element using Legendre type shape fuctions. The variations with respect to the different path of domain integrals from the crack-tip front and the choice of 5-function have been tested by several examples.

  • In recent years, as the population of ear and aged villages has increased, the problem of conflict between rural residents and urban-to-rural migrants has been widespread. For successful rural community, such conflict resolution is more important than anything else. However, if we look at previous studies. It is true that there are many studies that focus on people who are not rural residents or urban-to-rural migrants. This study was conducted to find out the difference of strategies for conflict resolution between rural residents and urban-to-rural migrants. This study derives the factors of conflict based on the contents of previous studies, To see the difference, five strategies were used from the response strategies that were used in the 'Computer Prisoner's Dilemma Contest' held by Axelrod (2009). I would like to know what kind of strategies of rural residents and urban-to-rural migrants. All analyzes were done using SPSS 22.0 for Windows, and the results of each conflict resolution analysis showed that the indigenous conflicts were low All. Among the causes of conflict, the highest level of conflict was caused by the 'rural residents who did not understand urban culture'. The strategy is the most used, followed by tit for tat Strategy, and all-c strategy, in that order. However, It is not uncommon for employers to use a work-type strategy, and it can be seen that the strategy changes depending on the cause. As can be seen from the above results, The conflict resolution strategies are almost similar strategies. It can be seen that conflict resolution strategy is used differently according to personality. The purpose of this study is to investigate the differences in conflicts in the rural areas. In particular, it is meaningful to examine the choice of solution strategies based on game theory through reviewing prior research and eliciting actual conflict factors in the field. Successful rural settlement can be achieved not through stakeholder competition but through mutual cooperation by gaining cooperation to the other side. Mutual cooperation is more profitable than betrayal in various conflict situations. The secret to maintaining and communicating smoothly is not to use the other person to fill his or her selfish interests, but to reject it for profit, but to draw cooperation from the other party.

  • Great tit (Parus major) is a bioindicator species that can measure environmental changes in urban ecosystems and plays an important role in maintaining health as a representative insectivorous bird. Researchers have utilized artificial nest box surveys to understand the reproductive ecology of the Paridae family of birds, including the Great tits, but it is difficult to conduct a macroscopic study due to spatial and temporal limitations. This study designed and applied a citizen-participatory monitoring of artificial nest boxes project to transcend the limitations of expert-centered monitoring methods. The Suwon Front Yard Bird Monitoring Team installed artificial nest boxes in green spaces in Suwon, Gyeonggi Province and observed the reproductive ecology of the Paridae family through the participation of voluntary citizen surveyors. Participants were recruited through an online survey from February 9 to February 22, 2021, and they directly performed from installation to observation of artificial next boxes from February 23 to August 31, 2021. Online education was provided to the volunteers for the entire monitoring process to lower the entry barrier for non-expert citizen surveyors and collect consistent data, and observation records were collected through a mobile app. A total of 98 citizen surveyors participated in the citizen-participatory monitoring of artificial nest boxes project, and 175 (84.95%) of the 256 distributed artificial nest boxes were installed in green spaces in Suwon City. Among the installed artificial nest boxes, the results of the citizen science project were confirmed for 173 (83.98%), excluding two boxes with position coordinate generation errors. A total of 987 artificial nest box observation records were collected from citizen surveyors, with a minimum of one time, a maximum of 26 times, and an average of 5.71±4.37 times. The number of observations of artificial birdhouses per month was 70 times (7.09%) in February, 444 times (44.98%) in March, 284 times (28.77%) in April, 133 times (13.48%) in May, 46 times (4.66%) in June, 6 times (0.61%) in July, and 4 times (0.41%) in August. Birds using the artificial nest boxes were observed in 57 (32.95%) of the 173 installed artificial nest boxes, and they included Great tit (Parus major) using 12 boxes (21.05%), Varied Tit (Parus varius) using 7 boxes (12.28%), and unidentified birds using 38 boxes (66.67%). This study is the first to consider citizen participation in the monitoring of artificial nest boxes, a survey method for the reproductive ecology of the Paridae family, including Great tits, and it can be utilized as basic data for the design of ecological monitoring combined with citizen science in the future.

  • This research was carried out from March 2009 to July 2012 to explicate the height change based breeding-ecological characteristics of Titmice that were breeding in the artificial nests installed in the Halla Mountain. The first egg-laying day was delayed as the height of the area under investigation increased, and it turned out that the decrease in temperature due to the elevated height had influence on that delay (p<0.05). Generalizing the annual results of the analyses, we see that there was no significant correlation occurring between the average temperatures and egg-laying days in the breeding season (April~June) (p>0.05). The rate of artificial nest use was not different among areas and among year, but between the species, Parus major and Parus varius. There were differences in clutch sizes among species (p>0.05), but no differences in heights and years (p<0.05). The hatching-, fledging-, and breeding-success rates were 67.3%, 99.5%, and 67.0% respectively in 2011, and 71.3%, 96.8%, 69.0% respectively in 2012, from which we can tell that the fledging-success rate was high but the hatching- and breeding-success rates were similar. Though we confirm that temperature changes due to height differences had influence on breeding periods, but we cannot identify a significant correlation with other breeding-ecological characteristics. Thus, in order to more precisely explicate the influence of temperature changes due to heights on Titmice's breeding, long-term research is needed in terms of the investigation of microclimatic factors and food resource.

  • Many information storage systems, such as database system, were needed to integrate much informations into one system and to provide mare voluminous lump of informations. But as the size of information system becomes larger, the responded result size of existing keyword based searching system might be too large and couldn't do the exact search which the user intends to. In this study, we proposed a paper searching method which uses RDF semantic. For this, we analyzed the structural forms of the tit1e of research papers and reconstructed them into RDF/XML. When we use these RDF descriptions of the titles to search papers, we could get more precise and accurate results than keyword based searching method.

  • This study focuses on the needs at both consumers and manufacturers. It aims to find ways for consumers to purchase outfits that would fit their particular body type and preferences at reasonable prices, choose raw materials and style at garments, and virtually try them on. In addition, the study is designed to help apparel manufacturers identity customers' changing needs, reduce inventories, manage information on customers' body type in a digitalized form, and eventually contribute to promoting electronic commerce. Based on nine basic patterns that tit each subject, 108 virtual garments are created by adjusting the size of the patterns (9 subjects $\times$ 4 body parts $\times$ 3 patterns = 108 outfits). In order to determine fitting preferences for each body part and find optimized conditions, cross-tabulation analysis including $X^2$ and frequency analysis were performed to measure the appearance rate. A style of virtual garment, which is minus 2cm from chest size was chosen as the most appropriate pattern to the baseline location of front the chest. For the waist parts, the C style as an appropriate virtual garment to front and back view. In the front, lateral and back view, a style was chosen in the response to the sleeve-bodice combinations, the ease amount of armhole area, the armhole depth and the loosening of tightening or armhole line.
