This study aims at developing the measurement tool of reading motivation using self-determination theory (SDT). SDT is not simply divided into the intrinsic and extrinsic motivation. SDT resides along a continuum, with amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, intrinsic motivation. SDT addresses the process of internalization of various extrinsic motives. This study analyzed motivation factor of the measurement tool such as MRQ (motivations for reading questionnaire), MRP (motivation to read profile) ERAS (elementary reading attitude survey, RSCS (reading self-concept scale). The study re-classified analysis results based on SDT. Ultimately, this study was proposed measurement tool of reading motivation using SDT has 6 area, 30 items.

This study explored how young people with disabilities experience self-determination in their lives. This study employed a grounded theory approach involving 10 undergraduate students with cerebral palsy or physical disabilities, in their early 20's, and individual interviews. The experience relating self-determination of the participants seemed to start with "wanting to do things at their will as they grow up". The participants reported experiencing "yearning to attain self-actualization overcoming disabilities" in the context of "disability-related social limitation", "divided opinions between the participants and their parents", and "limitation in financial and psychological resources". The emerging strategies to attain self-actualization included "active coping", "avoiding confrontation", and "conditional acceptance". Intervening conditions to formation of the strategies included ”challenging spirits towards prejudice about disability", "autonomous tendencies", "taking the most of social support" and "parenting attitudes of their parents". In the process of seeking to attain self-actualization, these participants experienced "self-maturation" and "the sense of guilt towards their parents". The findings emerged from the study was that there are three stages in the process young people went through in self-determination. The stages consist of "perceiving their needs and obstacles for self-determination", "problem solving", and "perceiving their growth". In addition, four self-determination patterns are derived from this data: "breaking through", "multi-strategic", "moderate", and "acceptive". This study suggested some theoretical and prctical implications needed to facilitate self-determination of youth with disabilities.

A theoretical expression for determining the effective magnetic moment of hematite(${\alpha}-Fe_{2}O_{3}$) particle of the parasitic ferromagnetism by the proton relaxation in water is derived. In deriving the expression it is found that the mathematical procedures are exactly the same as those applied for aqueous solutions containing free paramagnetic ions, except that the distance between the proton spin of water molecule and the corresponding electronic spin of the particle must be considered to be a radius vector rather than a relative distance. And it is also found that the average effective magnetic moment of the particle calculated by the expression is in good agreement with the experimental value determined by Hirai.

The purpose of this paper is to examine learning motivational process models, based on Self-Determination Theory(SDT) in academic settings. I examined if SDT's assumptions would fit for Korean adolescents, using a learning motivation scale(LMS), Basic Needs-autonomy, competence, and relatedness-Satisfaction Scale(BNSS), academic grades and life-quality scales, and also tried to search for the adequate motivational process models for Korean adolescents through regression analysis and structural equation model analysis. The results of this study are as follows. Basic needs satisfaction influences positively on the development of self-determinative motivation, which influences positively on academic achievement. But academic achievement and self-determinative motivation doesn't always influence on subjective well-being positively. And Korean adolescents who study autonomously or achieve good grades, are not better in a dimension of subjective well-being than others. Basic needs satisfaction while growing is more important than any other variables to improve adolescents' autonomous motivation, academic achievement and subjective life qualities.

In this article, a fairly extensive literature review was conducted to depict the current status of academic motivation and its developmental trend among Korean adolescents. The focal factors were perceived competence and autonomy which have been considered as major determinants of academic motivation. Theoretical frameworks adopted were self-efficacy theory, expectancy-value theory, and self-determination theory. Empirical studies conducted in Korean educational settings during the past decade were the target of the literature review. Results of the literature analysis revealed that, in general, there was a decreasing tendency in perceived competence from elementary to middle school which followed by a slight increase after entering high school. Similar trend revealed in the development of autonomous motivation, in that middle and high school students' intrinsic motivation levels were lower than that of the elementary groups. The amotivational tendency was increased as the grade level proceeded toward high school, which requires attention from educators. Discussion was followed in an attempt to provide plausible interpretations for this undesirable current status of Korean adolescents' academic motivation and to suggest implications for possible remedial actions both in pedagogical perspectives and students' well-being.

The phenomenon of magnetostriction occurs in magnetic systems when the temperature is changed or the external magnetic field is applied. It is known that the magnetostriction observed in rare-earth elements and compounds is well described by the crystal-field striction and the exchange striction. In this review paper, we discuss the standard theory for the magnetostriction which includes the crystal-field and the exchange interaction.

The purpose of the study is to explore the mental health social workers' experiences concerning client's self-determination by grounded theory, one of the qualitative method. Although a lot of previous studies has proved that the practitioners have suffered from the ethical considerations in their practice, on which the matter of client's self-determination is centered, little attention is paid to deep exploration of practitioners' real experience about those aspects. To carry out the research question, first, through literature reviews focusing on clarify the underlying issues about client's self-determination, three intrinsic clues are found out; incompetence, medical benefits, the harm to the third party. Data obtained by in-depth interview with 10 participants are analyzed by employing the methode developed by Corbin and Strauss, which could categorize the raw data into several high-level concepts and constructs. The findings of the study show that most practitioners would consider the clients as the intrinsic subject of self-determination. Therefore, in practice, they are trying to support the client's self-determination even within the some constraints. In addition, they also experience the clients' latent potential in actualizing autonomy and self-determination, and identifies the positive effect of self-determination not only on the client's self-help and mental health but also on the practitioners themselves. The results of the study clearly suggests that it is critical to provide the practitioners with adequate ethical education and training to help them to overcome their ethical suffering concerning clients self-determination.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.
