  • 본 연구는 신체적 특성과 기능적 움직임 검사(FMS)의 융합적 상관관계에 대해 알아보고자 한다. 연구대상자는 정상 성인으로 193명을 대상으로 단일측정하였다. 자료분석은 SPSS 26.0 Ver 프로그램으로 T-검증을 실시하였고, 각 변수들 간 피어슨 상관계수로 분석을 하였다. 분석결과, 검사 방법 중 능동 뻗은 다리 올림 검사와 몸통 안정성 푸쉬업 검사 영역에서 성별 간에 유의한 차이가 나타났다(P<.05). 어깨 가동성 검사와 능동 뻗은 다리 올림 검사 영역을 제외한 나머지 FMS의 검사에서 체지방률과 부적 상관관계가 있었다. 능동 뻗은 다리 올림에서 여성이 기능적 움직임의 질이 높았으며, 몸통 안정성 푸쉬업에서는 남성이 기능적 움직임의 질이 높았다. 그러므로 남성은 하지의 유연성을 보강해야하며, 여성은 상체 근력과 몸통의 안정성 운동을 적용해야 한다고 판단된다.

  • PET bottles are main]y manufactured by the stretch blow-molding process. In order to improve the thickness distribution to avoid crack generation at bottom region of one-piece PET bottle, process analysis of stretch blow-molding using a finite element method has been carried out. Finite element analysis has been carried out using ABAQUS/Standard. CREEP user subroutine provided in ABAQUS has been used to model PET behavior that is rate sensitive. Among the process parameters, the effect of plunger movement to thickness distribution of bottle has been considered by axisymmetric analysis. A modified process of plunger movement, which yields more uniform thickness distribution, has been proposed. 3D FE analysis has been done to confirm the validity of the proposed process.

  • Background: The functioning of the serratus anterior (SA) muscle is essential to normal scapulohumeral rhythm during forward flexion (FF) of the shoulder. Also, SA weakness and overuse of the upper trapezius (UT) is observed in patients with shoulder dysfunction and trapezius myalgia. We designed a combination exercise involving FF and scapular protraction with resistance (CFFSP) to activate the SA muscle and to deactivate the UT muscle. Objects: The purpose of this study was to determine whether or not CFFSP would be more effective in activating the SA muscle than FF alone and FF with scapular protraction (FFP). Methods: Nineteen subjects (12 men and 7 women) participated in this study and performed FF, FFP, and CFFSP at $120^{\circ}$. Surface electromyography was applied to the SA, UT, and pectoralis major (PM) muscles, as was one-way analysis of variance (ANOVA) with repeated measures. Statistical significance was set at .05. Bonferroni adjustment was used to counteract the problem of multiple comparisons, with a statistical level of significance of .017 (.05/3). Results: A statistically significant difference was found in relation to the three positions for the SA muscle (p<.001) and the SA/UT ratio (p=.005) using ANOVA. Significantly different results, depending on the position, were also demonstrated using the Bonferroni post-hoc test for the SA muscle ($FF=28.27{\pm}16.20$, $FFP=45.66{\pm}15.81$, and $CFFSP=62.4{\pm}27.21$) and for the SA/UT ratio ($FF=3.04{\pm}2.14$, $FFP=3.61{\pm}2.38$, and $CFFSP=5.95{\pm}3.01$). Significant differences between the three positions was not found regarding the average amplitude of SA/PM muscle ratio (SA/PM: p=.060). Conclusion: We recommend the use of CFFSP to strengthen the SA muscle at $120^{\circ}$.

  • ONE 시뮬레이터로 구현된 근무일 이동 모델은 교통수단을 이용하여 실제와 비슷한 환경을 제공한다. 하지만, 근무일 이동 모델은 교통수단 중에 택시 이동 모델은 누락되어 있다. 그래서 선행 연구로 택시 이동 모델을 ONE 시뮬레이터로 구현하였다. ONE 시뮬레이터 안에서 라우팅 프로토콜의 실험결과는 이동 모델에 따라 크게 달라진다. 그래서 본 논문에서는 ONE 시뮬레이터에 택시 이동 모델을 이용하였을 때, 전염 라우팅 프로토콜과 같은 DTN 라우팅 프로토콜의 성능 평가 결과를 분석한다.

  • Tough-construction is, undoubtedly, one of the most puzzling syntactic problems in the history of transformational grammar. Various approaches have been proposed including Deletion approaches (Akmajian, 1972; Lasnik and Fiengo, 1974) and movement approaches. Among the movement approaches, Chomsky (1977; 1981) argues for movement of null Operator, and Hornstein (2001) argues for a two-step movement equipped with Sideward movement. Most recently, Schueler (2004) and Hartman (2009) each have also argued for a kind of movement approach. With the development of the Minimalist syntax (Chomsky, 1995; Chomsky, 2000; Chomsky, 2001), tough-construction, an age old problem in the description of grammar, turns into another round toward to a more satisfactory answer. By examining the most recent competing analyses of tough-constructions, this paper defends and extends Schueler's (2004) analysis, rather than Hartman's (2009) two step movement approach. Furthermore, this paper proposes that tough-subject originates from the intermediate CP internal Spec-TopicP position rather than from the iterated CP layer (Authier, 1992). This approach has more descriptive power than it was originally argued for in Schueler (2004) and is a step closer toward Minimalism insofar as the conception of government is no longer utilized.

  • 캐릭터의 움직임은 내면에 흐르는 감정을 전달하기 위한 중요한 요소이다. 비록 동일한 움직임일지라도 캐릭터의 성격이나 감정 또는 상황에 따라 움직임은 다르게 나타나고 표현된다. 이 연구에서는 라반의 움직임 분석 체계인 Laban Movement Analysis(LMA)를 사용하여 겉으로만 보여지는 애니메이션의 움직임뿐만 아니라 캐릭터의 내적인 감정과 태도를 라반의 움직임 분석(LMA) 카테고리의 하나인 에포트(Effort)로 분석하여, 주로 무용계에서 활용되는 라반의 움직임 분석이 애니메이션의 움직임을 얼마나 효과적으로 분석할 수 있는 가를 알아보고자 한다. <몬스터대학교>는 겁주기 선수가 되고자 하는 꿈을 위해 끊임없이 노력하는 몬스터에 대한 이야기로, 기능적 움직임이 주를 이루지만 캐릭터의 생각과 감정을 표현하는 표현적 움직임도 조화롭게 나타난다. 겉으로 드러난 캐릭터의 움직임은 자신의 내면적인 감정을 잘 드러내는 경우도 있지만 감정을 절제하면서 움직이는 경우도 많다. 그러한 점에서 이 연구는 <몬스터대학교>를 연구대상으로 삼고 <몬스터대학교>의 네 가지 장면에 나타난 캐릭터의 움직임을 LMA의 에포트로 분석하였다. 연구결과, 마이클이 겁주기 선수를 따라 인간 세상과 연결된 문 안으로 들어가는 장면에서는 겁주기 선수를 부러워하는 마이클의 내면에 깔려있는 감정 상태를 꿈꾸는 것 같은 강한 느낌을 주는 환상충동(Vision Drive)으로 표현하고 있으며, 최고의 겁주기 팀을 선정하는 시합 중 두 번째 경기를 하는 장면에서는 경기에서 살아남으려는 확실한 움직임의 동기를 가지고 조심스럽고 가볍게 움직이는 마술충동(Spell Drive)을 느낄 수 있었다. 생존한 팀들을 위한 파티가 열리는 장면에서는 주위를 의식하지 않고 기쁘고 즐거운 감정표현에 집중하는 열정충동(Passion Drive)이 나타나며, 마이클과 설리반이 사람들에게 쫓기는 장면에서는 긴박한 캐릭터들의 내적인 감정을 한 곳에 집중시켜 점차적으로 빨라지는 동작과 무겁고 강한 움직임을 표현하는 동작충동(Action Drive)이 나타남을 알 수 있었다.

  • This study was to analyze the effect of dancesport heel-shoes heights on Rumba Cucarachas Movement in terms of analysis, and to provide the essential information to decide the proper heel-shoes heights for individual. six female subjects participated in this study. Dependent variables were set and divided into the amount of movement regarding the velocity and angle of the right elbow, pelvis, ankle, and knee. The following conclusion was drawn blow. 1) Angle: We all appeared in 5, 7, 9cm heel height so that we were similar in a knee and elbow angle and no significantly. The plantar flexion appeared greatly as an ankle angle's shoe high and significantly. 2) Velocity: An elbow velocity all appeared in a three shoes so that it was similar. We speed fast speed some in a 7cm heel height. A knee velocity expressed fast speed some in a 5cm heel height. The pelvis velocity in a that it was similar. Generaly, The aspect to be a dancesport competition o'clock and aesthetic is the height. and the muscular strength train after we need the thing to choose suitable to the individual shoe height. It is logical that the decision of heel-shoes heights should be made by anthropometric and sport dynamic analysis in order to maximize the dynamic and aesthetic aspect of dance sport.

  • Based on the camera movement on image expression and grammar, this study intended to analyze the characteristics of image expression filmed and broadcasted by drones. This study analyzed drone images using the movement characteristics of existing video cameras as a coding nomenclature. These were intended to examine the differences from existing video grammar and their implications. This study conducted a content analysis using the entire population of drone news footage broadcast for four years in 2015, 2016, 2017 and 2018 by TV Chosun. The size of the screen, camera work, duration of the shot, camera angle, etc. were selected and analyzed. As a result, the drone camera work showed that it uses the most dolly shots in the case of camera movement, followed by the drone camera movement in the order of pan and tilt shots. For zoom, the frequency of use was the smallest. In addition, this study analyzed the size of the screen, duration of the shot, and camera angle of drone. Analysis shows that drones use certain camera movements most frequently, and unlike grandiose modifiers such as "extension of human gaze," drone remains as a supplementary means to enhance the traditional media expression.

  • This paper is concerned with a chronological analysis of the simple limb movement and the performance of a selective response for Korean adults. The cybernetical control number(C.C.No) tester is used to perform the experiment for 103 males and 96 females aged from 20s to above 60s. For the selective response ecperiment, judgement speed has decreased with age. The judgement speed was slowed down more rapidly with age for female than for male. Both the limb movement and the judgement speed showed significantly different trends according to age groups. Especially, it was shown that simple limb movement decreased beginning with 50s for male and 40s for female. It is expected that the results can be applied to the job design of aged people.

  • In case of an urban tunnel, the displacement of ground base controls the tunnel design because it is built on shallow and unconsolidated ground many times. There are more insufficiency to describe the ground movement which coincides in the measured result of the situ because the design of an urban tunnel is dependent on the method of numerical analysis used to the existing elastic and elasto-plastic models. We studied about the prediction for the ground movement of a shallow tunnel in unconsolidated ground, mechanism of collapse, and settlement. Also this paper shows comparison with the existing elastic and elasto-plastic model using the unlinear analysis of the strain-softening model. We can model the real ground movement as the increasement of ground surface inclination or occurrence of shear band by using strain-softening model for the result of ground movement of an urban NATM tunnel.
