Despite consumers' increasing awareness and interests in innovative wearable devices, the sales growth has been stagnant. To analyze this phenomenon, we investigate consumer preferences for various innovative features embedded in wearable devices. Conducting conjoint analysis on smartwatches, we empirically show that the curse of innovation can occur when the consumer's expected utility from the smartwatch falls short of his/her psychological cost associated with behavior change from smartwatch usage. Therefore, our findings provide managerial implications on the R&D strategy for new technologies and more importantly on the marketing strategy easing consumers' resistance to highly innovative products.

A recognizable form having meaning is called a sign in semiotics. The sign is transformed into a physical counter form in this work. Its internal structure is restricted on the linguistic concept structure. We borrow the concept of a mathematical function from the utility function of a rational personal in the economy. Universalizing the utility function by introducing the consistency of independency on the manner of construction, we construct the probability. We introduce a random variable for the probability and join it to a position variable. Thus, we propose a physical sign and its serial changes in the forms of stochastic equations. The equations estimate three patterns (jumping, drifting, diffusing) of possible solutions, and we find them in the one-day stock-price flow. The periods of jumping, drifting and diffusing were about 2, 3.5, and 6 minutes for the Kia stock on 11/05/2014. Also, the semiotic sign (icon, index, symbol) can be expected from the equations.

Bullying is the intentional, unprovoked abuse of power by one or more children to inflict pain on or cause distress to another child on repeated occasions. Bullying can be considered to be a form of child abuse：peer abuse. Victims suffer adverse effects in the short and long term. If bullying is regarded as a form of abuse then professionals have a duty to detect it, take it seriously, and ensure that it is deal with to reduce the child's suffering and minimize the potential long term effects. This study is aimed preliminarily the development of cognitive behavioral group therapy for school bullied. 202 normal middle school freshman responded to self report scales- Offer's Self-Image Questionnaire-Revised, Children's Depression Inventory, Spielberger State/Trait Anxiety scale, and Defining Issues Test. The data were analyzed with Pearson's correlation to test the relationship among the above 4 variables. Self Image, depression, and anxiety were correlated strongly each other. But moral development was not correlated with self image, depression, and anxiety. Five school bullied students were referred by their teacher for school maladjustment. The author tried 12 sessions of Cognitive-Behavioral group therapy and assessed their behaviors pre- and post intervention by above 4 scales. There were no significant different intervention effects statistically. But It is meaningful that improvement of psychological mindedness in diary written by subject in treatment sessions

This research aims to study Michael Chekhov's acting techniques scientifically, because his techniques has been studied only theoretically or empirically. Especially, this study focuses on 'imagination' and 'Psychological Gesture' from the perspective of cognitive psychology. Chekhov thought 'imagination' as the basis and core of all the works of acting. In cognitive psychology, it is called as 'imagery' and means 'a representation of the mind of the object not communicated by the sensory organs currently'. This study starts with defining imagery and takes a brief look at the features and kinds of imagery. Then the researcher will prove scientifically the possibility of training acting using imagery as Chekhov's assertion. For the proof of the validity of imagery, we'll look for the theoretical evidences-functional equivalence hypothesis, psychoneuromuscular theory, symbolic learning theory, psychophygiological information processing-and experimental ones-measurements of cerebral blood flow or event-related potential, experiments with fMRI(functional magnetic resonance imaging) or PET(positron emission tomography). As a result, we can see that imagery is functionally identical to perception and improves fulfillment of cognitive and physical tasks. As proving physical changes can draw out psychological changes(feeling) on the medium of imagery, we can also see the validity of Psychological Gesture. From the above research, even if Chekhov developed the acting techniques only on the basis of his experience, his techniques can be thought as having scientific validity. Though insufficient, this study can be a help for actors or students as they using Chekhov's techniques.

Contributed acceptance system is causing problems with the usefulness and follow-up services and the like, other than the origin purpose which needs to be operated as rational adjustment method between the public interest and the private. Accordingly, this study has examine the problems by analyzing the present condition of practical public facilities and has the purpose on drawing the improvements by conducting consciousness survey from in substance users. The problems drawn from the analysis and the survey are location and position of the public facilities by reason of making public facilities at leftover land, the awareness and use as in-site facilities, creating street facilities without considering the use and safety of the users, follow-up service issues and the usefulness issues by creation without considering the surrounding conditions. The proposal of improvements for efficient operation by each problems are devising plans by considering location and position of the facilities for utilization and usefulness, secondly the necessity of the public relations for the improvements of the utilization of public facilities. thirdly, conducting the legal obligation by installing direction boards for its awareness of public facilities and delegating operation of facilities to public corporations such as SH, LH and inhabitants for efficient follow-up services, lastly, establishing the public facility map service which could figure out the surrounding conditions of public facilities to utilize for the contributed acceptance.

The purpose of this study is to develop a test tool that can be measured in various aspects for the reading attitudes of children. For that it was set the configuration based on the preceding reading attitude survey and models and tacit knowledge of attitude toward reading and wrote the questions for reading attitudes. It conducted a primary and secondary test for elementary school students in grades 4-6 to verify the validity and reliability of measurement tools. 8 factors of the reading attitudes measurement tool were extracted through exploratory factor analysis and it described 66.29% of total variable. the r-value for inter-item consistency about reading attitudes were above 0.4 on all questions. The Cronbach ${\alpha}$-value of reliability coefficient about reading attitudes measurement tool was 0.950. Therefore Reading attitude test tool have reading usefulness, reading efficacy, leisure, stiumulation, flow, expression, study, assertiveness as sub factors of reading attitude has been shown that it can serve as a useful tool for measuring various aspects of the reading attitude for children.

The EGI system is a new communication method in limelight for helping disabled users to input and handle information on the computer more easily. However, due to the EGI system's "JEM(Jittery Eye Movements)" generation, it actually increases heavy psychological and physiological stresses for the user to input or perceive the target information on a machine. This study illustrates how to resolve this "JEM" issue and suggests a method that is easy and simple to be controled by anyone. A demo tool was built and tested to find and prove the reasons for "JEM" This test shows that that the case with snap up is less stressful than without to input text as a final result of the test evaluation in both psychological snap up and physiological brain wave test. Postnatal or naturally acquired, it is found that the disabled can have opportunities for smoother communication, and a possible efficient system development for better communication.
