To analyze the applications of all types of mechanical systems, general purpose analysis programs have been developed and commercialized. However, it is customary to develop and use customized programs even though they sometimes require more work than a general purpose program. A customized program is simplified to adapt to a particular application from the beginning, is designed for small computers, and developed with hardware-in-the-loop in mind so it can be applied effectively. By adding design knowledge and bundling know-how to an analysis program, analysis time can be reduced. And because an analysis has to work in conjunction with other analysis programs, a proprietary program that the user can easily modify can be useful. In this thesis, a multi-body dynamics analysis system is presented using one of the most useful programming techniques, object-oriented concept. The object-oriented concept defines a problem from the physical world as an abstract object, an abstract model. The object becomes encapsulated with the data and method. Simulation is performed using the object's interface. It is then possible for the user and the developer to modify and upgrade the program without having particular knowledge of the analysis program. The method presented in this thesis has the following advantages. Since the mechanical components of the multi-body system converts independent modeling into a class, the modification, exchange, distribution, and reuse of elements are increased. It becomes easier to employ a new analysis method and interface with other S/W and H/W systems. To employ a new analysis method, there is no need to modify elements of the main solver and the Library. In addition, information can be communicated to each object through messaging. It makes the modeling of new elements easier using inheritance. When developing a S/W for the computer simulation of physical system, it is reasonable to use object-oriented modeling. Also, for multi-body dynamics analysis, it is possible to develop a solver that is user-oriented.

This study addresses the relationship between individual differences regarding self-concept, measured by Self Concept Clarity (SCC) scale and Relational-Interdependent Self-Construal and relationships (RISC) scale, and diverse affective consequences after choice behavior. We hypothesized that lower self-concept clarity and higher relational interdependence would be related to increased susceptibility to choice context-for example, how a choice set is constructed based on one's initial preference. We examined how variations in a choice set can produce different affective consequences after making choices, and investigated the underlying neural mechanism using fMRI. In this experiment, participants first rated their preferences for art posters, and made a series of choices from a presented set. After the choice task, they completed post-choice measures including preferences for the chosen posters, as well as measures of their self-concept clarity and relational interdependence. Our behavioral results demonstrated that when participants faced more conflicting choice context, self-concept clarity was related to more positive affective consequences after choice, whereas relational interdependence was correlated with a lower second-rated attractiveness of the chosen option. The neuroimaging analysis of choice-making revealed that self-concept clarity and the degree of their relational interdependence served as modulators in shaping how one perceives and experiences the same decision-making process. These results have theoretical and practical importance in that it is one of the first studies investigating the influence of the individual differences regarding self-concept on value-based decision making process among diverse choice set contexts.

This study examined the subcategories of the self concept of adolescent consumers, and investigated the influence of this self concept and the demographic characteristics on the evaluation and experience of adolescent entry into harmful places. The adolescent group was divided into 4 subgroups: (group I with negative evaluation and without entry experience, group II with negative evaluation but with experience;, group III with positive evaluation but without experience, and group IV with positive evaluation and with experience). The differences of demographic characteristic and self concept between these. subgroups were inspected. The results of this study were as follows. First, the self concept of the adolescent consumer consists of body self, social self, achievement self, scholarship self and family self. Among these self concepts, scholarship self was the highest, and family self was the lowest. Second, from the result of regression analysis using the demographic element as an independent variable to inspect the factors influencing self concept, sex, school year, living with parents, and economic status were statistically significant. Third, in case of entry evaluation, singing room was evaluated most positively among 10 places with a score of 4.20 and pub/drunkenness was evaluated most negatively. In case of entry experience, singing room was the most frequently experienced place and discotheque was the least. Fourth, with respect to demographic characteristics and influences of self concept, the influencing factors on entry evaluation were sex, school year, social self, and family self, and the influencing factors on entry experience were sex, school year, living with parents, social self, and family self. Finally, examination of the differences of demographic characteristics and self concept according to entry evaluation and experience, revealed the distinctive variables among the 10 harmful places to be sex, school year, living with parents, body self, social self, achievement self, scholarship self, and family self.

Various and complex cultural phenomena have led to many changes in the space. The concept of unconsciousness, among others, and experimental expression technique and the concepts from surrealism that rather attaches great importance to contingency than intentional attempt have been employed in the space. The abstract expression as expressional characteristics of surrealism makes the space ambiguous through the concept of automatism using the approach of indeterminism and double image expression, and represents the space providing diversity through the dualism. In contrast, objective expression, which was based on depaysement, generates the tension and expresses the dramatic situation in such a way and manner which are intentional, distorted transformed, together with heterogenous meanings aligned through the reversal appeared in the techniques of collage and paranoiac-critical method. However if such space accommodating the expressional characteristics of surrealism is approached as superficial concept in analyzing the human's inner consciousness and imaginary society, expression of the ultimate concept contained in the expressional characteristics of surrealism can hardly be achieved. Hence, the spatial analysis from the semiotic approach, instead of unilateral method aimed to convey the meaning only, which creates the signification, was adopted. The study, as effective approach to the space accommodating the expressional characteristics of surrealism, was intended systematically evaluate the concreteness of understanding and generation of meaning through the semiotic method. Greimas' semiotic square analysis to the space plays the important role in generating the spatial meaning, as well as is needed for objective analysis of the importance of various characteristics and methodology which the space contains through the expressional characteristics of surrealism.

Purpose: The purpose of this study was to conduct a concept analysis of social intelligence in nurses so that applying social intelligence to the nursing field. Methods: In this study, we followed the hybrid model procedure, involving the following steps: First, in the theoretical stage, the attributes and definitions of the concept of social intelligence were determined through literature review. Second, the concepts' reality was confirmed during fieldwork. In the final analysis stage, the results confirmed in the theoretical and fieldwork stages were compared and analyzed to confirm the properties and definition of the concept. Results: Nurses' social intelligence consists of three dimensions: social cognitive nursing competency, human-centered social evolution, and skills for solving complex nursing situations. Nurses' social intelligence is a professional nursing competency that flexibly coordinates complex nursing situations, developed through accumulating experiences of continuous reflection and relationship expansion based on receptive listening and social sensitivity in clinical interpersonal relationships. Conclusion: Nurses' social intelligence is widely used in clinical practice and is shown to have a significant direct and indirect impact on clinical nursing. To effectively apply social intelligence in the clinical context, individual and organizational efforts are required to share and transfer knowledge and capacity-building methods through collective intelligence and education.
