Nowdays, many people suffer from the neck pain due to forward head posture(FHP) and text neck(TN). To assess the severity of the FHP and TN the craniovertebral angle(CVA) is used in clinincs. However, it is difficult to monitor the neck posture using the CVA in daily life. We propose a new method using the cervical flexion angle(CFA) obtained from a wearable sensor to monitor neck posture in daily life. 15 participants were requested to pose FHP and TN. The CFA from the wearable sensor was compared with the CVA observed from a 3D motion camera system to analyze their correlation. The determination coefficients between CFA and CVA were 0.80 in TN and 0.57 in FHP, and 0.69 in TN and FHP. From the monitoring the neck posture while using laptop computer for 20 minutes, this wearable sensor can estimate the CVA with the mean squared error of 2.1 degree.

In a pop song, the creator's intention is communicated to the user through music and lyrics. Lyric meaning is as important as music, but in most cases lyrics are delivered to users in a static form without non-verbal cues. Providing lyrics in a static text format is inefficient in conveying the emotions of a music. Recently, lyrics video with kinetic typography are increasingly provided, but producing them requires expertise and a lot of time. Therefore, in this system, the emotions of the lyrics are found through the analysis of the text of the lyrics, and the deep learning model is trained with the data obtained by converting the melody into a Mel-spectrogram format to find the appropriate emotions for the music. It sets properties such as motion, font, and color using the emotions found in the music, and automatically creates a kinetic typography video. In this study, we tried to enhance the effect of conveying the meaning of music through this system.

본 연구에서는 새로운 휴대폰을 구매한 후, 처음으로 사용 동작을 익히는 과정에서 소비자들이 기존의 '텍스트 매뉴얼'과 실험을 위해 가상현실로 제작된 두 가지 '애니메이션 매뉴얼' 가운데 최적의 매뉴얼을 찾아내기 위한 연구를 수행한 것이다. 조사 방법은 세 가지 태스크로 나누어 실험하였다. '애니메이션 I' 매뉴얼은 동작 영상과 기본 음향을 게시한 방식이고 '애니메이션 II' 매뉴얼은 '애니메이션I' 매뉴얼에다가 화면상의 부수적인 설명과 음성을 추가한 것이다. 그리고 평가방법은 세 가지 비교평가를 각각 의 t-검증과 부가적인 주관적 평가 법으로 연구와 평가를 하였다. 분석결과는 다음과 같은 결론을 얻을 수 있었다. 첫 번째 결과는 '텍스트 매뉴얼 보다 '애니메이션 매뉴얼' 들이 쉽게 이해하고 따라하기 쉬웠다. 두 번째는 '애니메이션 I 매뉴얼'보다 '애니메이션II 매뉴얼'이 더욱 익히기 쉽다는 결론을 얻을 수 있었다. 테스트 후 설문 및 인터뷰에서 멀티미디어로 제작된 '애니메이션 매뉴얼'에 높은 관심을 나타냈다.

This article examines Laurence Sterne's Sentimental Journey in the context of eighteenth-century British travel literature. While literary critics generally read Sterne's work as a sentimental novel, contemporary readers initially interpreted the text as a travel narrative. It is my argument that travel writing, particularly the motion entailed in travelling, plays a significant role in Sterne's critical examination of sympathy and its cultural function during this period. By narrating in great detail his narrator Yorick's mobility and the effects it has on his sentimental encounters, Sterne illustrates how sympathy is not only difficult to activate and therefore requires added stimulation in the form of motion, but also does not necessarily result in charitable actions, a moral failure that is dramatized by the literal distance Yorick maintains from the objects of his sympathy. Calling to mind the figurative distance that constitutes an integral part of Adam Smith's formulation of sympathy in The Theory of Moral Sentiments, the distance Yorick establishes through his travels indicates sympathy's failure to bridge the emotional and socioeconomic distance between individuals, thereby highlighting sympathy's limitations as a moral instrument. I argue that by using Yorick's repeated acts of sympathy to explore the problems of sentimentalism, Sterne both draws from and innovates the tradition of employing imaginary voyages to engage in philosophical inquiries.

In this paper, we introduce a biped walking robot which can do static walking with 22 degree-of-freedoms. The developed biped walking robot is 480mm tall and 2500g, and is constructed by 22 RC servo motors. Before making an active algorithm, we generate the motions of robot with a motion simulator developed using C language. The two dimensional simulator is based on the inverse kinematics and D-H transform. The simulator implements various motions as we input the ankle's trajectory. Also the simulator is developed by applying the principle of inverted pendulum to acquisite the center of gravity. As we use this simulator, we can get the best appropriate angle of ankle or pelvic when the robot lifts up its one side leg during the walking. We implement the walking motions which is based on the data(angle) getting from both of simulators. The robot can be controlled by text shaped command through RF signal of wireless modem which is connected with laptop computer by serial cable.

In late 19C, German mathematician Felix Klein declaired "Erlangen program" to reform mathematics education in Germany. The main ideas of "Erlangen program" contain the importance of instructing the concepts of functions and groups in school mathematics. After one century from that time, the importance of concepts of groups revived by Bourbaki in the sense of the algebraic structure which is the most important structure among three structures of mathematics - algebraic structure. ordered structure and topological structure. Since then, many mathematicians and mathematics educators devoted to work with the concepts of group for school mathematics. This movement landed on Korea in 21C, and now, the concepts of groups appeared in element mathematics text as plane rigid motion. In this paper, we state the rigid motions centered the symmetry - an important notion in group theory, then summarize the results obtained from some classroom activities. After that, we discuss the responses of children to concepts of groups.of groups.

비디오는 멀티미디어 데이터의 가장 대표적인 형태로, 텍스트나, 이미지, 오디오와 객체의 움직임 같은 풍부한 정보를 담고 있다. 비정형의 멀티미디어 데이터를 다양하고 효율적으로 표현하기 위해서는 XML(extensible Markup Language)을 사용하여 저장하고 검색하는 멀티미디어 검색시스템이 필수적이다. 그러므로 멀티미디어 데이터에 대한 검색을 위해서는 멀티미디어 데이터의 내용을 구조적으로 설명하는 메타데이터가 필요하고 이 메타데이터를 XML을 사용하여 표현하며 저장하고 검색하기 위한 멀티미디어 검색시스템이 요구된다. 본 논문에서는 XML 메타데이터 모델링 기법과 이 모델링 기법을 지반으로 한 멀티미디어 검색시스템을 제안한다.

Modern people communicate in a digital space without being limited by physical space and time. On the internet, people's desire for self-expression is getting bigger, and the most common self-expression tool is characters. Characters are visual materials to express human thoughts and desires. This study is a method to positively express the viewer's self in an interactive Hangeul system. The proposed system produces new formative shapes and meanings of Hangeul through the process of deconstructing and reconstructing the characters. Immediate character transformations that are synchronized with the motion of the viewer act as a tool of self-expression by inducing the viewer's active interaction repeatedly. Therefore, the proposed interactive Hangeul is more than enough to be used as a new graphic tool beyond the text to be read, and it is highly likely to develop into cultural contents using it.
