  • In this study the stress analysis of orthotropic thin plate with arbitrary shapes for different boundary conditionsis investigated. Meshfreemethod is applied to static analysis of thin plates with various geometries based on the Kirchhoff classical plate theory. According to the meshfree method the domain of the plates are expressed through a set of nodes without using mesh. In this method, a set of nodes are defined in a standard rectangular domain, then via a third order map, these nodes are transferred to the main domain of the original geometry; therefore the analysis of the plates can be done. Herein, Meshless local Petrov-Galerkin (MLPG) as a meshfree numerical method is utilized. The MLS function in MLPG does not satisfy essential boundary conditions using Delta Kronecker. In the MLPG method, direct interpolation of the boundary conditions can be applied due to constructing node by node of the system equations. The detailed parametric study is conducted, focusing on the arbitrary geometries of the thin plates. Results show that the meshfree method provides better accuracy rather than finite element method. Also, it is found that trend of the figures have good agreement with relevant published papers.

  • In order to help the theory development for "women health", and to apply to the women client care, the concept analysis of "women health" was done. According to the concept analysis method by Walker & Avant, the characters of concept "women health" were analyzed from literature. The results were as followings : first, it emphasizes reproductive focused health care(childbirth-oriented) and normal development process regarded as abnormal. Second, it is affected by cultual environment. Third, it is related with sex. Forth, it considers the human, feminine and maternal aspects. Fifth, it need woman-centered nursing approach to promote woman's quality of life. Sixth, it stresses not only wholistic human health promotion but also the harmony between human and environment. Seventh, it is needed to be considered woman's various experiences as important and it approaches phenomenogically and interdisciplinary. Eighth, it needed to understands person-situation interactional aspect. Ninth, it can promote the adaptation power to surrounding environment. Above results can elucidate the concept of "women health", and will be a basis of theory development of "women health" In practical nursing, these results will be a basis for the promotion of women health and for the increase of life quality.

  • This study ultimately aims at suggesting the improvements for community development policy in Korea. In order to do so, this carried out field surveys for two rural villages and tried to find out the current institutional situation of rural villages. Reviewing conceptual debates on rural, village, community and organisation theory, it sets up a typology of four groups as follows: voluntary expressive group, involuntary expressive group, voluntary instrumental group, and involuntary instrumental group. Based on this typology, this study conducted field surveys for two rural villages; Pyeongchon-Ri in Chungnam and Noolmi-Ri in Kyoungbuk. From the analysis on the field surveys, it finds some features on Korean rural groups. First, the residents in rural villages have very strong identity for their living areas. Second, the number of rural groups are tend to decrease recently. Third, the actions of instrumental groups are determined by the organisations operating nearby. Fourth, the function of groups within rural villages only carry out some village festivals, but other friendly relationship among rural residents are expanded out to wider areas called Myeon. As a result, this study suggests that we should recognize the diversity in rural communities in Korea and deals with them in different ways of public policies.

  • This research employs the grounded theory approach among various qualitative methodologies in order to reach a deep understanding of both the experiential process that children undergo in block play and the essential meaning of it. The objects of this study are 22 children(female 7, male 15) in a 5-year-old class of K kindergarten at Guro district, Seoul. The result of this research shows that first, children take pleasure in block play because of the delight and sense of accomplishment in building, the joy in demolishing, and the happiness of embracing the world through dramatic play with building structures. Second, the characteristics of children's block play are popular subject of the play, decision of the subject, impromptu transformation and elaboration of building structures, and flow of the play according to friend/non-friend relationship. Third, the implicit rules shared by children have more significant influences upon the block play than the agreed rules at the beginning of semester.

  • The purpose of this research is to analyze the manifestation of children's color education in the software in order to evaluate conditions of color education as well as improvement of its direction. The procedure and method of the research is begun from evaluating the characteristic of children's developmental stage, content analysis of the nation's organization of color education and analysis and evaluation of education program through the investigation on 8 different softwares in reward for the tournament. The results are as followings; First, the research shows that the elementary school stage of color education is inadequate in comparison to children's cognitive developmental stage. Second, most of the color theory was composed of characteristic of a color, stimulation of emotion and effects of psychology. Considering of children's cognitive development, it is necessary to make up for the basic of color theory and the system of color. Third, Softwares of color education program for 1 st. and 2nd grade in elementary school was so rare that it should be properly developed and made for systematic contents. Fourth, color education for the 5th and 6th grade children remained in understanding basic characteristics of the color which is below the par and brings the necessity for more professional and structural contents.

  • The CLI(Consumer Life Information) is a new study to unite and create new values recognizing the importance of knowledge and information in information-oriented society based on domestic science and digital technology. The objective of this research is to define academic identity of consuming science and CLI, to analyze the theory, styles, manners, psychology and the concept of consumption, which is the base of consuming life, and to present the direction of CLI with tasks and three major axises of CLI. Nowadays, international order demands new paradigms from human beings. Especially, vision and creation of the values are settled as methodological ways considering the economic power. The CLI should be on the same horizon adjusting social change of pointing values and quality in consuming patterns of diversity and variety. Therefore, I would suggest the ways for the CLI to head for as follows. First, it is to perceive the 3 major Axises & Task of CLI. Second, it is to develope service (experiencing goods) and goods that can lead consuming lives. Third, it is to study merchandising strategy, to create new signs and symbols of goods, and to collaborate of R & D(reseach and developement) and Business. Fourth, it is to head for globalization. Consequantly, this study will be helpful to establish the theory of relationship between producer and consumer in fashion business included research and developments of qualitative goods.

  • Nowadays when the social and cultural paradigm is changing, the incomplete space is becoming a matter of controversy. In order to figure out the solutions to it, are being held a variety of spatial discourses for spatial essence and meaning to be cleared. Accordingly, this study has tried to seek for any probability to interpret the ontology shown at any traditional space on the ground of Heidegger's Ontological Thinking Structure which has a considerable impact on Modern Space, whose conclusions are the followings. First, Heidegger's ontological space theory, which provided a foundation of Placeness concept, includes not only the character of interdisciplinary learning among philosophy, arts and any related studies but also that of mutual oriental and occidental cultures. Second, between the thoughts of Heidegger and Lao-tzu are considerable similarities from the methodical viewpoint that materializes the meaning of existence as an essence. Third, for a convenient interpretation, the ontological spatial concept of Lao-tzu's philosophy shown at traditional spaces have been categorized into Typology-Incident, Morphology-situation and Topology-meaning generation with Schultz's Existential Spatial Concept based on Heidegger's Ontology as a medium. In particular, the meaning generation which materializes the placeness has the trait of being clarified as the product of interactions between incidents and situations.

  • In this paper, We analyze Colpitts type voltage contrqlled oscillator(VCO) used in personal handheld phone using a nonlinear analysis with third-order model. The resul shows the non-exponentially decaying shifting bias superimposed on the oscillator output which is different with the exponentially decaying shifting bias from the linear analysis. The stable oscillation criterion during a frequency change in a design of VOC can be also determined using proposed non-linear analysis. The theory is confirmed using PSPICE simulation and the experimental result of GaAs VCO matched very well with the theory.

  • This study examined smoking behavior of Korean female college students by applying the Ajzen's Theory of Planned Behavior, and tried to uncover the factors influencing smoking behavior. The main findings are as follows: First, the attitude toward smoking behavior and the perceived behavioral control were statistically significant in predicting smoking intention. The smoking intention was also significant in predicting smoking behavior. Thus, in order to promote to stop smoking, smoking prevention education emphasizing to reduce smoking intention, to lower the positive attitude toward smoking behavior and to enhance the capacity for perceived behavioral control seems to be helpful. Second, the smoking intention influenced significantly over the smoking behavior in all situations. But the influences of the attitude toward smoking behavior, the subjective norms, and the perceived behavioral control over the smoking intention varied from not significant in one situation to significant in the other situation. Thus, different prevention programs according to the characteristics of individuals need to be developed. Third, in a path analysis, the grade and the degree of satisfaction with college life had the indirect influence, and the growth place had the direct influence over the attitude toward smoking behavior and smoking intention. Thus the smoking prevention program focusing on the students who are the first grade, less satisfied with college life, and growing up in small cities should be developed.
