RFID 시스템에서 태그의 위치를 추적하기 위해서 궤적은 모델링되고 색인되어야 한다. 궤적은 태그가 판독기의 인식영역으로 들어갈 때와 나갈 때 보고되는 두개의 시공간 위치를 연결한 선분으로 표현될 수 있다. 만약 태그가 판독기의 인식영역에 들어와 나가지 않으면 시공간 위치는 오직 태그가 인식영역에 들어올 때만 보고된다. 따라서 판독기에 머물고 있는 태그는 궤적을 표현할 수가 없으므로 질의 시 이러한 태그를 검색할 수 없다. 이러한 문제를 해결하기 위하여 이 논문에서는 태그의 궤적을 시간 매개변수 간격으로 정의한다. 시간 매개변수 간격은 시간에 따라 시간 축길이가 변하는 시간에 종속적인 선분으로 판독기에 머무는 객체의 궤적을 표현할 수 있다. 또한 RFID 시스템에서 사용되는 질의를 분류하고 효율적인 처리를 위해 태그의 식별자를 차원에 추가하는 방법을 제안한다.

The purpose of this study is to have an opportunity to enhance the role of cultural intermediaries in the region as interest in the cultural media sector increased with the implementation of the Law for Promotion of Regional Culture. First, I discussed the need to pay attention to the local Cultural Intermediaries group as the background of the discussion, confirming that the existing research on the cultural mediation sector was focused on cultural workers in public institutions and government projects. Next, for the theoretical discussion, I reviewed the role of cultural intermediaries contributing to the production of meaning via the concept of cultural intermediaries by Pierre Bourdieu, and described that the mediation of regions and cultures began to emerge as an alternative to the existing centralized structure of cultural production in the context of Korea after the late 1990s. It was found that practices that mediate the region and culture were developed around the group of public artists and cultural activists and the intermediary group played a role in revealing various aspects of the region and dynamically constructing the local public sphere through these cultural practices. Lastly, local curator's cases (Space Beam, Space Imsi, Incheon Spectacle) were studied. The actual cases of activity were analyzed through the cultural practices by focusing on what alternative meanings had been produced in the region and how the region was represented. Each case showed the mediating activity that attempts to change the environment of life while sharing local issues with communities, projects that reconstructs the local professional art sector into a public sphere, and mediating activity that represents local daily culture and form networks through independent publications.

The purpose of this study is to investigate relationships among scientific self-efficacy, achievement in science and cognitive self-regulation learning strategy. The subjects were composed of 158 elementary school students. Data of students' self-efficacy related to science and cognitive self-regulation learning strategy measured by questionnaire were analyzed. Science achievement scores were also collected. The results indicated that self-efficacy and cognitive self-regulation learning strategy predicted science scores. The findings showed that cognitive selfregulation learning strategy mediated the relation between self-efficacy and achievement in science. Memory learning strategy, considered a cognitive self-regulation learning strategy, did not mediate the relation between self-efficacy and science scores. The implications of science education to develop students' science achievement in the classroom and the suggestions for future researchers are discussed.

This study examined the relationship among dropout, organizational trust, and intention to transfer in the department affiliated with Physical Education. Data were collected from 480 students in the department affiliated with Physical Education from 6 institutions of a 4-year university located in Seoul, Gyeonggi-do, Incheon, and ChungChong-do. For the research model analysis, a structural equation model and bootstrapping were conducted. Results indicated that the academic domain, the social domain, and the environmental domain of dropout had a positive effect on organizational trust. But the only the academic domain in the relationship between dropout and intention to transfer affected intention to transfer positively. The social domain and the environmental domain were not statistically significant on intention to transfer. Moreover, organizational trust had a positive effect on intention to transfer. Finally, organizational trust partially mediated the path between the academic domain and intention to transfer. It fully mediated the paths between the social domain and the environmental domain and intention to transfer.

We proposed a method for locating of mouth using deformable templates, described by a parameterized template. An energy function is defined which links, edges, peaks, valleys in image intensity to corresponding properties of the template. The template deforms itself by altering its parameter values to minimize the energy function. The minimized energy function's parameter values can be used as descriptors for the feature. We propose a method for locating mouth fast, accurately by limiting a range of parameters' value and getting initial value of parameters' by preprocessing.

This paper presents a more stable method of multiresolution editing for a triangular mesh. The basic idea of our paper is to embed an editing area of a mesh onto a 2D region and to produce 3D surfaces which interpolate the editing-information. In this paper, we adopt the extended convex combination approach based on the shape-preserving parameterization for the embedding, which guarantees no self-intersection on the 2D embedded mesh. That is, the result of the embedding is stable. Moreover, we adopt the multi-level B-spline approach to generate the surface containing all of 3D editing-information, which can make us control the editing area in several levels. Hence, this method supports interactive editing and thus can produce intuitive editing results.

매개변수가진에 종속되는 현의 횡방향진동을 시간영역에서 필터작업, 힐버트 변환과 순간주파수 개념을 도입하여 해석함으로서 종방향의 순간진동변위를 추정하는 방법이 제시되었다. 그리고, 실험을 통하여 이론의 타당성을 검증 하였다. 또한, 모의 실험의 결과 일반적인 현구동계에 있어서는 넓은 적용변 수의 선\ulcorner영역에서 종변위가 횡변위와 분리(decoupling) 되어서 공간적으로 길이에 따르는 선형적인 증가성과 시간적으로 조화적인 주기성을 가진다는 것을 확인함으로서 임의의 위치에서의 종변위를 파악함이 가능하였다.

The study examined the influence of character on adjustment to college life in focused on the mediating effects of interpersonal relationship 220 dental hygiene students located in G, J regions between July 23, August 20 in 2018. The data was analyzed by descriptive, pearson correlation coefficient and regression in order to mediating interpersonal relationship using SPSS 18.0 program. The dental hygiene students got a mean 3.50 in character. Among the inferior factors of character, it got 3.55 knowing factor and 3.60 feeling factor and 3.38 behaving factor. Character was positively correlated with interpersonal relationship(r=.74, p<0.01) and with adjustment to college life(r=.63, p<0.01). Interpersonal relationship(r=.65, .69, .77, p<0.01) and had a positively correlation with adjustment to college life(r=.56, .56, .68, p<0.01) interpersonal relationship was positively correlated with adjustment to college life(r=.80, p<0.01). Interpersonal relationship had perfect mediating effects on the relationship between the two. The study suggest that the interpersonal relationship of the dental hygiene students did an surely mediating role between character and adjustment to college life.

최근 저자는 혼합모우드에 대한 Budiansky와 Rice의 $J_k$ 적분에 모순이 있음을 지적한 바 있다. 그러나, Kishimoto등은 파괴진행영역을 고려한 경로 독립적분J/^/을 제시하여 주목을 끌고 있다. Landes등은 Rice의 J적분을 정상상태 크리이프에까지 연장 적용하기 위한 $C^*$적분을 소개하였다. 그후 크리이프파괴에 대한 매개변수로서 Liu등에 의한 $C_{gk}{\;}^*$, Brust등에 의한 $T_k{\}^*$등이 소개되어 계속 연구중이다. 여기에서는 이러한 매개변수들에 대해 개괄적으로 서술하고자 한다.

현대에 이르러 초음속 운영 영역에서의 항공기에 대한 많은 연구가 진행되고 있으나, 음속 폭음 현상과 충격파 현상에서 야기된 높은 항력 및 연료 효율성 저하로 인하여 그 한계에 부딪치고 있다. Busemann 복엽 익형은 이와 같은 문제를 해결하기 위한 형상이며, 상하 형상에 의한 파동 상쇄효과 및 파동 감소효과를 통해 충격파의 강도와 음속 폭음 효과를 감소시키는 형상이다. 하지만 본 익형은 탈설계 조건에서 항력 계수가 급격하게 증가하는 등의 문제점을 가지고 있다. 본 연구에서는 EDISON_CFD를 이용하여 Busemann 복엽 익형의 주변 유동 특성에 대하여 면밀한 고찰을 수행하였다. 우선 Busemann 복엽 익형의 초기 형상에 대한 유동 조건별 해석을 통하여 탈설계 조건에서의 항력 성능 저하 문제에 대한 고찰을 하였다. 이후 3개의 형상 변수에 대한 매개 변수 연구를 통하여 익형의 각 형상 변수가 탈설계 영역 및 해당 영역에서의 최대 항력 계수에 미치는 영향에 대한 고찰을 수행하였으며, 이를 통하여 기존 형상보다 좁은 탈설계 구간을 가지고, 최대 항력 계수가 약 34.8% 감소한 부스만 복엽 익형을 설계하였다.
