A new axisymmetric crack model is proposed on the basis of p-version of the finite element method limited to theory of small scale yielding. To this end, axisymmetric stress element is formulated by integrals of Legendre polynomial which has hierarchical nature and orthogonality relationship. The virtual crack extension method has been adopted to calculate the stress intensity factors for 3-D axisymmetric cracked bodies where the potential energy change as a function of position along the crack front is calculated. The sensitivity with respect to the aspect ratio and Poisson locking has been tested to ascertain the robustness of p-version axisymmetric element. Also, the limit value that is an exact solution obtained by FEM when degree of freedom is infinite can be estimated using the extrapolation equation based on error prediction in energy norm. Numerical examples of thick-walled cylinder, axisymmetric crack in a round bar and internal part-thorough cracked pipes are tested with high precision.

The purpose of this study were (1) to thumbnail sketch of present general condition of foreigners and international marriage in Korea, (2) to study special trend of international marriage in rural Korea, particularly immigration connected with poverty, and (3) to focus on prospect of the problem of mixed-bloods, especially half blood children in rural Korea. Many of foreigners were treated discriminatingly, for example racial discrimination and wage discrimination. And discrimination to mixed-blood children will be happen in future. They are in a disadvantageous position because of economic status and appearances. Half blood children have korean nationality because one of his parent is korean. When they grow up and reach their the age of puberty and the age of working, they will resist to discrimination in working and marriage. I had examined precedent studies, and class theory in general, and to suggest it is time to looking for way of reduce social cost and way of coexistence.

Normative models for explaning the career decision-making process are not sufficient to enable the career counselor to help a client understand and influence the factors affecting his career. Actually, the particular people and life events that are unpredictable and subject to chance often influence on career behavior. Therefore, it is needed the development of a models of career decision-making that recognizes both normative and chance influences. The focus in this article is on the development of career decision-making within various lift contexts and the recognition that individuals may prepare themselves to use unexpected opportunities in the career decision-making process.

This paper reviews the concept and limits of rural community development, examines the relation between consciousness education and movement, and suggests the model of social consciousness education to rural community movement. Since consciousness education is closely related to social movement methodologically, organizational and systematic community development movements for re-structuring the urban-oreiented policies and education which back up them be followed as natural consequence. Based upon the results of this study, the new paradigm is suggested. As shown in the model, new understanding of urban-rural continuum theory, new roles and concept of social consciousness education should be emphasized to solve the contemporary rural community problems. The organizational community development movement for the rural-oriented policy should be an essential process, and peoples' re-orientation, such as 'breaking stereotype', 'assumming a critical thinking toward social reality' etc., is the indispensible background of successful movement.

Many optimization problem or multiple attribute, multiple alternative decision making problem may have fuzzy evaluation factors. In this case, fuzzy number operation technique is needed to evaluate and compare object functions which become fuzzy sets. Generally, fuzzy number operations can be defined by extension principle of fuzzy set theory, but it is tedious to do fuzzy number operations by using extension principle when the membership functions are defined by complex functions. Many fast methods which approximate the membership functions such as triangle, trapezoidal, or L-R type functions are proposed. In this paper, a fast fuzzy number operation method is proposed which do not simplify the membership functions of fuzzy numbers.

The information matter-element system was built to assess safety of water source. Based on the thought of multiindex fusion, fuzzy matter-element model evaluating water source behavior was constructed by matter-element transform. This model can process comprehensively hydrogeological data, ecological environment, water pollution, surface disturbance, and so on. Water source safety behavior can be described by the qualitative and quantitative manners. According to the development trend of quantitative results, water source safety behavior can be expressed dynamically. As an example, the proposed method was used to assess safety status of 7 water sources in the region. The numerical example shows that the proposed method is feasible and effective, and the evaluation results are reasonable.

The healing tourism has been growing rapidly in Korea. This study examines the restoration experience of rural healing tourism by qualitative method. The restoration environment is based on nature, and rural areas are the representative places for nature-based tourism. Therefore, this study aims to explore the meaning of restoration experiences of rural healing tourism. An in-depth interview process was used as the primary qualitative research method for this study. Nine interviews were given and from a thematic analysis of the data, six themes of restoration environments were emerged. The restoration environment of the rural settings are as follows; being away, fascination, extent, compatibility, healing nature, and leisure activity. Attention restoration theory provides a model that helps explain the results of this study. The results of this study can be useful for establishing effective marketing strategies through understanding the restoration environment in rural healing tourism.

The aim of this article is to critically explore the history, methods, characteristics and cause mechanism of Korean farmers' movement who resisted to market globalization from the perspective of social movement theory. I believe that the most influential elements of Korean farmers' movement are three structural elements; namely resentment, political opportunity structure, and media and discourse. Therefore, focusing on the three elements, I analyze the emergence and expansion of the Korean farmers' movement against market globalization from 1993 to 2008. And I analyze the roles of these three structural elements which played in farmers' social movement in South Korea. Particularly, this article analyses in perspective of market globalization and government trust crisis about the basic reason why Korean farmers' movement was so fierce in process of agricultural market globalization.

This study aims to examine agricultural college students' perception of readiness and barriers towards implementation of ICT program. Data were gathered from 175 student of agricultural college in Korea. Descriptive statistics, exploratory and confirmatory factor analysis, t-test, and one-way ANOVA were applied to analyze the data. Results reveal that technology usefulness perception scores were high among the readiness components, but students readiness and school infrastructure readiness were low. Results also shows that policy and technology factors were also seen as the main barriers of ICT program implementation. Findings show that demographic variables did not significantly affect readiness and obstacles. The results of this study can provide guidance to the government or agricultural college organizations when considering readiness and barriers towards implementing ICT programs. In addition, this study contributes to improve the theory of adoption behavior and contributes to the foundation for future research aimed at improving our understanding of agricultural college students' behavior.
