Smart is becoming a social fever since Apple had invented iPhone. It looks old fashioned, if the word Smart is missed in TV, phone even white electronic goods. Korean's major firms made a slogan Smart Work as an important business strategy and tried to implement some activities. These Smart trends influenced the way people's working and organization. In this research, we explore the key factors related to smart work and empirically test the significance of antecedent variables such as Dynamics, Collaborativeness, Connectivity in determining the smartwork level. The statistical result, based upon survey responses, shows that organizational dynamics, organizational collaborativeness and process collaborativeness are the most salient factors for smarkwork level. As a conclusion, the academic and practical implications of these findings are also discussed.

Sit-to-stand movement is a basic movement in daily activities. On the basis of this movement, the biomechanical functions of a person can be evaluated. The study of the joint kinematics, moment, and muscle coordination is necessary to understand the characteristics of the sit-to-stand movement. We have developed a motion-based program for inverse dynamics analysis and the electromyogram-based program for muscle force prediction. The joint kinematics and the kinetic results estimated on the basis of obtained motion data, ground reaction force, and electromyogram signals were compared with those reported in previous studies, and the muscle forces determined by the two methods were compared with each other. The methods and programs developed in this study can be used to understand biomechanics and muscle coordination involved in basic movements in daily activities.

This study attempts to discuss holistic information in order to identify the characteristics of interactions using a graphing calculator. The use of a graphing calculator was divided into three stages: Visual, Analytical, and Self-regulated. The last stage can be called the Self-regulated instrument stage, because this last stage, the use of the calculator, is generally characterized as students actively controlling their ongoing efforts through self-regulating. The accomplishments of the operation can be divided into three levels: Immature, Maturing, and finally, Mature level. First, the characteristics of the Leading Statements were investigated to figure out who has the main role in cooperative learning. This study can support the previous study, which showed that computers could help improve the self-esteem of low-level students. Second, the point of transformation is referred to as the Turning Point. Several functions were observed in the Turning Point: student, instrument, and teacher. Third, when the students convert-sations reach a lull in class and then resume due to certain primary factors without the teachers intervention, this is a case of what is referred to as Structuralization. And last, in this study, the graphing calculator can be used as an auxiliary stimulus to help students control their stress and their attitudes, which in turn can also improve students social interaction.

This study focuses on the fact that intrinsic motivation which becomes the force to promote narrative is reinforced as a polyphonic structure through the psychodynamics of fear and desire internalized in a character, and from this perspective, it analyzes character rising strategies shown in Pixar's movie, . To verify fear and desire of a character, this study uses Enneagram personality types theory as the frame of analysis and reaches the following conclusions: (1) The main character, Carl's emotion originated from fear and desire was metaphorized as Muntz and Russell each, so the inside psychodynamics and the outer event visualizing it are set as contrapuntal composition. (2) However, inversely to the enhancement of Carl's polyphonicity, that excellent strategy works as the limit that restricts the psychodynamics of Muntz and Russell to a certain range. Lastly, it is expected that this study will be suggested as a sort of methodology about character rising strategies as turned into the database to which the result of follow-up research will be added, too.

The purpose of this paper is to introduce the current trends of British Music Therapy and its effectiveness as a therapeutic intervention for the autistic children. This paper consists of two parts；Part one will provide a general picture of music therapy by looking at its fundamental concepts and therories. Part II(two case studies) will illustrate the actual processes of music therapy which can engender a therapeutic relationship between the therapist and the autistic child. Through the first case study of Charlie, a 3 year and 9 month non-verbal autistic boy, we shall see how music therapy facilitates both non-verbal and verbal communication and a form of pretend play. The second case of Mark, a 10 year old autistic boy with complex emotional, behavioural and learning difficulties who had been sexually abused in the past, presents how the therapist’ acceptance of the child’ being and the shared experience of music therapy enable the child to express his difficulties and to develop the awareness of self and others. By exploring both musical and interpersonal aspects of music therapy, this gives an in depth examination of therapeutic processes. In order to clarify clinical procedure, this paper is viewed in musical, developmental and psychodynamic perspectives. To ensure confidentiality, the clients will be referred to by alter-native forenames.

Snapping triceps syndrome is a rare disease in which medial head of triceps dislocates over the medial epicondyle during elbow flexion. It is difficult to diagnose the snapping triceps syndrome, because that this syndrome is frequently misdiagnosed as other elbow disease such as ulnarnerve dislocation. The dynamic ultrasonographic imaging allows continual visualization of the ulnar nerve and triceps muscle throughout active elbow flexion and extension. We report two patients of snapping triceps syndrome who were diagnosed with the use of dynamic ultrasonography and treated with ulnar nerve anterior transposition and repositioning or resectioning of medial head of triceps.

The existing multiple modulus-based self-recovering equalization type has not been applied to initial equalization. Instead, it was used for steady-state performance improvement. In this paper, for the self-recovering equalization type that considers the multiple modulus as a desired response, the initial convergence performance was improved by extending the dynamics of the errors using error boosting and their characteristics were analyzed. Error boosting in the proposed method was carried out in proportion to a symbol decision for the equalizer output. Furthermore, having the initial convergence capability by extending the dynamics of errors, it showed excellent performance in the initial convergence rate and steady-state error level. In particular, the proposed method can be applied to the entire process of equalization through a single algorithm; the existing methods of switching over or the selection of other operation modes, such as concurrent operating with other algorithms, are not necessary. The usefulness of the proposed method was verified by simulations performed under the channel conditions with multipath propagation and additional noise, and for performance analysis of self-recovering equalization for high-order signal constellations.

Using a solution of $^{137}$ Cs as a tracer, radioactivity of a $^{137}$ Cs solution is measured by coincidence and anticoincidence counting methods. Sample sources in this study are fabricated by mixing $^{137}$ Cs with tracer, and the mixing ratios are 1/3 and 1/5, respectively in coincidence and anticoincidence methods. Specific activities of a $^{137}$ Cs solution are calculated by means of f-channel low energy threshold level variation and efficiency extrapolation. The results obtained by coincidence and anticoincidence counting methods are 552.78 kBq/g and 554.32kBq/g, respectively on the reference date and the combined uncertainties are 1.60kBq/g and 1.51kBq/g for each method. These two results show a good agreement within the uncertainty range.
