The electrical muscle stimulator (EMS) based human machine interface (HMI) free to mechanical constraint and muscle fatigue problems are proposed for force feedback in a virtual reality. The device was designed to provide force feedback up to 4.8 N and 2.6 N each to the thumb and forefingers. The main objective of the HMI is to make unnecessary mechanical structures to attach on the hand or fingers. It employs custom EMSs and an interface arranged in the forearm. In this work, major muscle groups such as extensor pollicis brevis (EPB), extensor indicis proprius (EIP), flexor pollicis longus (FPL) and flexor digitorum profundus (FDP) are selected for efficient force feedback and controlled individually. For this, a human muscular-skeletal analysis was performed and verified. The validity of the proposed multi-channel EMS based HMI was evaluated thorough various experiments with ten human subjects, interacting with a virtual environment.

The purpose of this study was to investigate the relationship of toddlers' vocabulary ability with reading activities and teachers' verbal and nonverbal behaviors during book reading. The subjects were 52 teachers and 104 toddlers at age 2. Lee and Kim (2004)'s categories of the Teachers' Verbal Behaviors, the categories of the Nonverbal Behavioral Analysis(Kim. 2005), and the Peabody Picture Vocabulary Test-Revised (Kim, et al.1995) were used. The data was analyzed by t-test, ANOVA, and Correlations. The results indicated that there were significant correlations in the subcategories of reading activities in classrooms, teachers' picture book reading behaviors, and toddler's vocabulary ability. The toddler's vocabulary ability increased as the 'interacting time both before and after book reading' became longer. The toddler's vocabulary ability increased as 'connecting with previous experience', 'asking questions for confirmation', 'acknowledging,' and 'expanding' of verbal behavior, as well as the nonverbal behavior, such as 'requesting behavior', 'emotional contact,' and 'empathetic behavior.' In conclusion, teachers' reading behaviors and activities were related to toddlers' vocabulary ability.

Objective: This study aims to investigate the effects of a learning cycle model-based early childhood education program using physical motion on young children's scientific inquiry ability, scientific attitude, object manipulation ability and spatial ability. Methods: The subjects of this study were 60 five-year-old children who were attending K-G City Childcare Center. The SPSS Window 21.0 program and content analysis method were used, and post-validation Tukey was conducted to examine the differences between the one-way ANOVA and the group. Results: Activities using body movement were practiced systematically based on the circle learning. Children could revise their pre-concept and concept of error by interacting with other children, teachers and the environment. Furthermore, children were attaining new knowledge while they were doing body movement activities, assessing and applying them to actual activities. Conclusion/Implications: This study is investigated a cyclic learning-based early childhood science education program using physical motion, which has significance in systematic and practical early childhood centered education for young children.

The aim of this thesis is to clarify the application of Derrida's 'Deconstruction' theory on the contemporary costume. Derrida's theory of 'Deconstruction' took into the 'decentring' concept which deconstructed the subjects i.e., Occidentalism, Elitecentrism, logocentrism, mancentrism etc.; it deconstructed the dichotomy that had been expressed in the traditional occidental metaphysics, by raising the isolated ones such as the Orient, sub-culture, ir- rationality, madness, woman etc. Summarizing the conclusion of this thesis as follows, 1. The impact of 'Deconstruction' from the inside is to be seen in the principles of intertextuality of the costume, therefore it has shown the bisexual costume by interacting gender, and the costume by mixing time, place and occasion. 2. $\ulcorner$Dis$\lrcorner$ deft phenomena which shows the concept of escape from the center were presented as decentring, dislocation, discomposition, disorder. 3. Undecidability principle resulted in the undecidable presentation in the wearing styles such as wearing, unwearing, layering. Contemporary costume by the 'Deconstruction' from the inside regards costume as a dynamic text, which has attempted the interaction with the other genres. It deconstructed the teleology of the costume function, and it accepts all the various aesthetic principles.

The purpose of this study is to examine how integrative art therapy affected the interaction of children with developmental disorder with their mothers from the viewpoint of object-relation theory that accentuated mother role for the promotion of mother-child interaction, and based on earlier studies on mother-child interaction and the interaction of children with developmental disorder with their mothers. The subjects in this study are five selected children and their mothers who used B and G social welfare agencies in Gyeonggi province. They are at the age of five and six in Western age, and have difficulties interacting with their parents. When a social maturity test is conducted, their social age ranged from 2.1 to 3.9, and as Portage Test is implemented, their developmental levels of sociability, cognition and language were identical to those of younger children who were at the age of one to 3.5. The major findings of the study are as follows. First, the children who suffered from developmental disorder and participated in this study showed a positive change in their interaction with their mothers. Second, as for connections between each session and mother-child interaction, most of them came to interact with their mothers better as the program came to an end.

Pen-input displays, such as LCD tablets and tablet PCs, are already popular for its usability in CAD design, in particular. in concept design phase. We propose an intuitive B-Spline modification scheme that can be used for the CAD systems targeting for such devices. Differently from the control point based modification schemes for the B-splines, our scheme relates user pen marking to determining the final shape of the target curve and surface. This, eventually, reduces time for interacting with the shape parameters (i.e., by control points or direct manipulators), which has been regarded as an unavoidable routine tasks for design. To prove its usability, we made an experiments with selected subjects who have been working for industrial design.

We study Diriclet forms and related subjects for the Gibbs measures of classical unbounded sping systems interacting via potentials which are superstable and regular. For any Gibbs measure $\mu$, we construct a Dirichlet form and the associated diffusion process on $L^2(\Omega, d\mu), where \Omega = (R^d)^Z^\nu$. Under appropriate conditions on the potential we show that the Dirichlet operator associated to a Gibbs measure $\mu$ is essentially self-adjoint on the space of smooth bounded cylinder functions. Under the condition of uniform log-concavity, the Gibbs measure exists uniquely and there exists a mass gap in the lower end of the spectrum of the Dirichlet operator. We also show that under the condition of uniform log-concavity, the unique Gibbs measure satisfies the log-Sobolev inequality. We utilize the general scheme of the previous works on the theory in infinite dimensional spaces developed by e.g., Albeverio, Antonjuk, Hoegh-Krohn, Kondratiev, Rockner, and Kusuoka, etc, and also use the equilibrium condition and the regularity of Gibbs measures extensively.

As research management is growing in importance for research organizations, their disciplinary structures need to be interpreted. However, it is not only difficult but ambiguous to detect causal relations between subjects because diverse disciplines interacting with each other lead the development of organizational research. Therefore, this article summarizes the major concepts and results recently achieved in the related fields such as research management, bibliographic analysis, information theory, and networks to characterize organizational knowledge structures. Relevant analytical methods obtained from the literature can be applied to empirical situations. Predictive causal relations can be measured using an information theoretic indicator on a series of organizational research portfolios identified from bibliographic information. A network approach would be suitable to manage organizational research effort from a holistic view. Knowledge structures of the Government-funded Research Institutes in Korea are explored experimentally.

This study explored the influence of adolescent depression on adult media addiction by examining Bronfenbrenner's ecological perspective. The ecological perspective is a useful framework to identify the link between youths' interacting subjects in the ecological environment. It can also be used to understand adolescent problems and addiction behaviors. The current study examined the influence of parents, peers, and teachers on adult media addiction and depression with a focus on micro-systems that have the greatest influence on adolescents among various environmental systems. We analyzed 568 participants who reported exposure to adult media. SPSS 20.0 was used to conduct a descriptive analysis of the data; AMOS 19.0 was used to conduct a confirmatory factor analysis and structural equation model. The results of study are as follows. First, parental abuse and peer alienation significantly increases depression. Second, peer communication significantly decreases depression. Third, parental monitoring and parental affection significantly decreased adult media addiction. Fourth, parental abuse, peer alienation, and depression significantly increased adult media addiction. This study is meaningful in that it examines the influence of parent, peer, and teacher relationships among adolescents on adult media addiction and depression. This study can be helpful to understand adult media addiction and depression among Korean adolescents.

The purpose of this paper is to compare the two different instruction methods for Korean learners of academic purposes in learning request expression. Participants were divided into two groups, explicit and implicit group. Both groups viewed several scenes from the drama that involved native speakers interacting in different situations. The instructional treatment for the explicit group included metapragmatic information while the treatment for the implicit group did not. On the other hand, the treatment for the implicit group followed implicit techniques, which were repetition of the video presentation and a script reading activity. This study was made up of a pre-test, a post-test, and a delayed-test. The pre-test was conducted prior to the instructional treatment. The post-test was administered a day after the last instruction and the delayed-test was conducted five weeks after the treatments. Two types of tests, speaking and writing, were used in this study to examine subjects' knowledge of Korean request. The result of this research reveals that implicit treatment was more effective than explicit treatment in Korean learners' request acquisition. This results might have been due to the operationalization of the implicit condition in this study. Implicit instruction may help language learners make rules by themselves through tasks.
