In this work, some inaccuracies and limitation of prior indentation theory, which is based on the deformation theory of plasticity and experimental observations, are first investigated. Then effects of major material properties on the configuration of indentation load-deflection curve are examined via incremental plasticity theory based finite element analyses. It is confirmed that subindenter deformation and stress-strain distribution from the deformation theory of plasticity are quite dissimilar to those from incremental theory of plasticity. We finally suggest the optimal data acquisition location, where the strain gradient is the least and the effect of friction is negligible. This data acquisition point increases the strain range by a factor of five.

Nursing have been caught between the paradigm of medical science with a body part view of a person and the paradigm of medical science with an emphasis on unsurpassable control, rigor, objectivism, and neutrality of value. But it is inappropriate to apply impersonal, objective model of science for the personal unique and gestalt experiences of nursing phenomena. Jean Watson proposed a theory of human caring based on human science paradigm to explain human phenomena. This study reviewed the theory of nursing by Jean Watson and the researches based on Waton's theory. In this study the researcher examined the philosophical back ground, value system and key concepts of Watson's theory Watson's perspective of person and human existence includes humanistic and phenomenological characteristics. She also emphasized nurse-patient relationship as an intersubjective(transpersonal) caring relationship. Examination of the studies based on Watson's theory consistantly revealed Watson's theory of human caring based on the human science paradigm is more appropriate than traditional medical science paradigm for explaining nursing phenomena. For the purpose of refining the theory and promoting usefulness of the theory, it would be desirable to test the theory to the nursing phenomena and to apply the theory to practice and education.

After Industrial Revolution, new thought system is needed to subdue multi-chanties and complexities of society. Nowadays under 'system theory', these efforts are theorized and organized in fields of science, philosophy and others. From Industrial revolution, before establishing the system theory, system has been needed by the expression methods. From that time, as it could be done, standardization, has been continued. Finally these conclusion reached at the systematic expression methods and when the system was build up, this theory was come true in Art such as De Stijl, Neo-Pasticism, Russian Suprematism and Constructism. For that reason, formal solution to achieve mass reductions was found in Art, so people connected Industry with Art at that time. Systematic expression methods in Art have characteristics of system and reflect mathematics and geometry theory which is based on the system theory. This study analyzes the systematic methods in contemporary interior space through the concept of systematic expression methods in Swiss Allianz's works which used the systematic expression methods and also inquires how the common meaning of system after recent times effect to contemporary design.

This study is the analysis of characteristics of hospital space for the holistic healing environment of children on the basis of the healing theory on emotion of Max L$\ddot{u}$scher and the healing theory on senses of Rudolf Steiner of the overseas children's hospitals. According to the theory of Rudolf Steiner, children make comprehensive advancement of physical, spirit and soul through the interaction of 12 senses. In addition, Max Luscher asserts that the psychological health can be maintained when the 4 emotional status in content, confidence, self-esteem and liberty make the balance. The 4 elements of Luscher have correspond with spatial expression elements for refuge, flow, prospect and void, and this is analyzed in conjunction with the eight kinds of behavior affordance of ying and yang (-, +) that helps our the advancement of 12 senses of Steiner. WORK & STUDY(+), REST(-), MOBILITY(+), VISUAL SEQUENCE(-), SOCIAL EXCHANGE(+), REFRESHMENT(-), COMMUNITY(+) and MEDITATION (-) would be the 8 kinds of behavioral affordances to make the healing environment as presented in this study and the case analysis for children's hospitals have been undertaken.

Dredged soil experiences large settlement during consolidation because of its high water contents. Large settlement alters the thickness of the consolidation layer greatly with time. However, the consolidation theory proposed by Terzaghi assumes the thickness of the consolidation layer to stay constant. Mikasa has developed a more rational theory considering the change of thickness of consolidation layer but it is not well applied at the site. In this study consolidation tests have been performed using Rowe cell for the four dredged clay samples with a water content of 100%, 120%, 133% and 150%. From the test results compression index characteristics and coefficient of consolidation characteristics have been investigated. Coefficients of consolidation obtained by Terzaghi's and Mikasa's theories, have been evaluated and compared with each other. When Mikasa theory is applied in the field design, the period to reach the required degree of consolidation has been reduced compared with the result by Terzaghi theory because the time factor $T_{v}$ by Mikasa theory decreases with increasing of final strain of consolidation layer, Calculation method consolidation time by Mikasa theory was concisely explained for its practical use.e.

Objective The purpose of this study was to show that the characteristics of the Sasang Constitutional Medical theory(SCM) are different from the traditional medical theory by comparing their theories of humans and pathophysiology. Methods The establishments and developments of the traditional medical theory were reviewed. Then the hypothesis that the theoretical foundation of SCM is different from that of the traditional medical theory was tested by comparing the traditional medical theory and SCM with respect to the theories of humans and the reconstructed theory of pathophysiology. Results The main findings of this study can be summarized as follows. 1. The theory of SCM reconstructed the traditional medical theory by shifting the paradigm concerning the structure of human existence. 2. The theory for SCM reconstructed the theory of pathophysiology by expanding Confucian moral theory from an experiential perspective. 3. The theory of SCM categorizes humans into four constitution groups according to congenital individuality in emotional expressions and pathophysiological functions. The categorization is based on medical treatment through which it was found that there are congenital individuality in the expression of his moral feelings. 4. The reconstructed pathophysiological theory of the SCM provides the foundation for establishing a verifiable medical theory. Discussion and conclusion The Sasang Constitutional Medical Theory is based on the idea that humans do not follow the changes of Nature but pursue morality and wealth in the Sasang system of the Heavenly qi and human affairs. Therefore, the theory is founded on Confucian moral theory but develops its own view of the theory of pathophysiology by way of experiential interpretation.

This study investigated the appearance management aspects of middle-aged male CEO's based on Bourdieu's class theory. We conducted in-depth interviews with male CEOs in their 40s and 50s to understand the characteristics of appearance management in terms of economic, cultural and social capital. We found that they acquire educational capital based on their parents' economic capital and form their own cultural capital as adults. They had the characteristics of Petit Brujois, which aimed for a higher class. The characteristics of differentiation based on appearance management identified three results came from solidifying one's class position: clothing management, diversifying and upgrading appearance management, and pursuing their own ideal image. The influence of social network and cultural capital was also observed in appearance management. This study explored the characteristics of discriminatory appearance management through an in-depth study of middle-aged male CEOs as well as contributed to understanding the context of capital and appearance management by applying Bourdieu's class theory. In addition, this study provides basic data that can be referred to a design and marketing direction for the men's clothing market by providing information on male consumers with high purchasing power.

In this paper a simple theory is presented to represent characteristic of a SRM and theoretical results are compared with experimental ones. In the theory the inductance variation of a SRM are approximated as linear and winding resistance and the magnetic saturation are ignored. With these approximations we derived some equations expressing load characteristics of a SRM Also the torque ripple was removed by applying a variable hysteresis band control.
