The purpose of this study is to investigate intrinsic values with respect to the nature of aim from the viewpoint of Dewey. The intrinsic values have been recognized as values independent of activities or the content that preexist before embodied into activities. But from the perspective of Dewey, intrinsic values can be revealed only through the activity. Because they are inherent in the activities. Dewey suggested that the educational aim that is influenced by the traditional metaphysics should be meaningless in that it is given from outside and not related to human activities. The educational purpose that influenced by modern metaphysics and contemporary theories also can be regarded external, because the content and value of learning are assumed ahead activities. In the view of Dewey, the concepts of values are exposed through activities, so they can not exist independently. According to his own metaphysics that organism and its environment interact each other, all values c an be formed only in the course of activities. Thus, the intrinsic value of Dewey is a process per se, as the intrinsic value cannot be assumed ahead activities but can be exposed through activities. Bringing meaning to life through experience is Dewey's concept of growth as an educational aim. Education under such a purpose, would give the foundation to cultivate talent who are creative, proactive and communicate with their neighbors as a member of a democratic society.

The purpose of the Nash embedding theorem was to take extrinsic help for studying the intrinsic Riemannian geometry. To realize this aim in actual practice there is a need for optimal relationships between the known intrinsic invariants and the main extrinsic invariants for Riemannian submanifolds. This paper aims to provide an optimal relationship for CR-warped product submanifolds of locally conformal Kähler manifolds.

The aim of the present paper is to establish an intrinsic generalization of Cartan connection in Finsler geometry. This connection is called the vertical recurrent Finsler connection. An intrinsic proof of the existence and uniqueness theorem for such connection is investigated. Moreover, it is shown that for such connection, the associated semi-spray coincides with the canonical spray and the associated nonlinear connection coincides with the Barthel connection. Explicit intrinsic expression relating this connection and Cartan connection is deduced. We also investigate some applications concerning the fundamental geometric objects associated with this connection. Finally, three important results concerning the curvature tensors associated to a special vertical recurrent Finsler connection are studied.

The cognition of an intrinsic attribute play an important role in the process of theoretical generalization. It is the aim of this paper to study how the theoretical generalization is made. First of all, we suggest the What-if-only-strategy(WIOS) which is the strategy helping the cognition of an intrinsic attribute. And we propose the process of the theoretical generalization that go on the cognitive stage, WIOS stage, conjecture stage, justification stage and insight into an intrinsic attribute in order. We propose the process of generalization adding the concrete process cognizing an intrinsic attribute to the existing process of generalization. And we applied the proposed process of generalization to two mathematical theorem which is being managed in middle school. We got a conclusion that the what-if-only strategy is an useful method of generalization for the proposition. We hope that the what-if-only strategy is helpful for both teaching and learning the mathematical generalization.

The aim of the study is to explore how to approach the inherent value of nature, which is the main object of earth science education, beyond its instrumental value, which is its external usefulness. Above all, it is said to be an activity-based inherent value in the entire transfer process of the experiment, which includes psychological elements. At the core of environmental ethics is value and the utilitarian question of what is worth continuing. It is a matter of more than simply continuation. The answer is the sustainable value of the natural environment, an education that must preserve its beauty as an inherent value, that is, as a heritage value as a lover of life. Furthermore, the area of valuation must be upgraded from synchronic to diachronic ethical values, with sustainable values instead of intrinsic values. In environmental ethics, the intrinsic value that shows the beauty of knowledge itself is called bequest value. The study distinguished between a priori intrinsic value that ignores existing experience and intrinsic value that is experience-oriented and activity-oriented. In addition, the intrinsic value principle centered on activities was explored through scientific experiments in earth science education and Eratosthenes's earth size measurement experiment. The value principle according to the scientific worldview serves as the basis for value judgment. Above all, intrinsic value was being revealed through the active value experience of the experiment, in which aesthetic values were involved in the process of inferring the experiment results. As an educational implication, it should be value-education that helps us internally transfer intrinsic values rather than instrumental values, which are the basis for creating a sustainable society and nature.

Historically the value of the secondary Home Economics subject matter has been justified with the extrinsic aim to satisfy the needs of the individual and family and of the society. The purpose of this study is to investigate the educational and philosophical significance of the knowledge in Home Economics education through reasoning out its intrinsic aim. From the point of discipline-based curriculum, Home Economics as 'the structure of knowledge' constitutes the curriculum of the secondary Home Economics subject matter and contributes to understanding the family life intellectually with its unique perspective. When students understand these theoretical contents, they will internalize the core idea of Home Economics so that their cognitive perspective on family life is developed or widened. With this cognitive perspective, they are able to discover the aspect of family life from their daily life, to interpret and judge every situation properly. It is the presupposition of socially expected practical problem solving that makes Home Economics education intrinsically meaningful. In conclusion, the secondary Home Economics curriculum needs to be reinterpreted or reorganized as the structure of knowledge, not as fragmentary informations or facts, through which the broad cognitive perspective on family life is developed and Home Economist's mode of thinking is transmitted.

The aim of this study is twofold. First, this study aimed to explore how Korean university students' English learning motivation is related to their English listening proficiency and study time. Second, it attempted to interpret the English learning motivation linking the two different motivation theories: self-determination theory and L2 motivational self system. The constructs of the students' L2 learning motivation were investigated with the data obtained through the questionnaire from 122 sophomore students. A factor analysis was conducted to extract the major factors of motivation. As a result, 6 factors were extracted: Intrinsic Pleasure, Identified Value Regulation, Intrinsic Accomplishment, Introjected Regulation, External Regulation, and Identified Regulation. The Interrelatedness among the assessment results on the L2 listening proficiency (pre and post test), listening study time, and motivation factors was measured by correlation coefficients. The statistical results indicated that pre-test scores were significantly related to Identified Regulation and Identified Value Regulation toward English learning, and post-test results had significant correlation with Intrinsic Accomplishment and Identified Regulation. However, no motivation subtypes showed statistical association with the students' listening study time. The results were attempted to be interpreted both under L2 motivational self system and self-determination framework to better illuminate the motivation theory with more explanatory power.

An application that has a simple user interface not only motivates a user to continue using the application, but also enables the user to develop their mental model for the application - the like of which is a product of their interaction with the application. In the information systems literature, little empirical research has been undertaken on the effects of the mental model and motivation on smartphone users' behavioral beliefs. Therefore, the aim of this study is to suggest a research model that can examine the following: 1) the effects that the mental model has not only on smartphone users' behavioral beliefs (that is, perceived usefulness and ease of use of an application) but also on their behavioral intention to use an application and 2) the effects that smartphone users' intrinsic motivation has on their behavioral beliefs through an expansion of the mental model. A survey is conducted, and structural equation modeling is then used to analyze the survey data. The results, through consideration of variables such as intrinsic motivation, perceived usefulness, perceived ease of use, and user satisfaction, indicate that the mental model has an indirect effect on a user's intention to use an application.

The aim of this paper is the study of instability state of boiling water reactors with a method based in largest Lyapunov exponents (LLEs). Detecting the presence of chaos in a dynamical system is an important problem that is solved by measuring the LLE. Lyapunov exponents quantify the exponential divergence of initially close state-space trajectories and estimate the amount of chaos in a system. This method was applied to a set of signals from several nuclear power plant (NPP) reactors under commercial operating conditions that experienced instabilities events, apparently each of a different nature. Laguna Verde and Forsmark NPPs with in-phase instabilities, and Cofrentes NPP with out-of-phases instability. This study presents the results of intrinsic instability in the boiling water reactors of three NPPs. In the analyzed cases the limit cycle was not reached, which implies that the point of equilibrium exerts influence and attraction on system evolution.
