In order to develop a safe geological disposal concept for the HLW from the nuclear power plants in Korea, it is necessary to evaluate the safety of the disposal concept in an underground research tunnel in the same geological formation as the host rock mass. The design concept of a research tunnel depends on the actual disposal concept, repository geometry, experiments to be carried at the tunnel, and geological conditions. In this study, geological investigation had been carried out to develop the basic design of the small scale underground disposal research tunnel in KAERI.

Purpose: The purpose of this study was to analyze the concept of social support of nursing students using a hybrid model and to derive a definition and attributes of social support through theoretical, fieldwork, and final analysis stages. Methods: Twenty-nine studies were analyzed in the theoretical stage. Seventeen in-depth interviews were conducted with nursing students in the fieldwork stage. In the final analysis stage, the concept of social support was defined and the attributes were derived by integrating the theoretical and fieldwork stages. Results: The attributes of social support of nursing students identified in the final analysis consisted of two dimensions and eight attributes. The two dimensions were structural and functional support. The eight attributes were social network, educational, emotional, informational, economic, positive evaluation, self-esteem support, and support by providing a role model provision. The structural dimension included the social network support attribute. The functional dimension included the remaining seven attributes. Educational support and support by providing of a role model provision were newly derived attributes that reflected specific characteristics of nursing students. Conclusion: Based on the results of this study, we suggest that researchers should attempt to develop a scale to measure the social support of nursing students.

In the latest furniture design field, we can find mass production with concept of heterogeneity that is made by harmonizing existing object with other object, which has new value. In order to follow the trend in the reality, various design process method that applied concept of Hybrid is attempted by flexibly combining or changing heterogeneous materials, formations or functions such as combination of new material and wood or IT. However, not like other design fields, its research range in furniture design is limited. This study is conducted in order to overcome and supplement problems that are made when these different materials are combined, such as faults or cracks made due to difference of expansion and contraction coefficient, lack of intensity and change of formation due to external temperature and humidity. Panels that are combined for this study were verified materials that have passed environmental adaptation test throughout the period of 1 year and 2 months, which will be made into a table. By doing this, this study will be an empirical study that establish concept of furniture made with acrylic and provides manufacturing method of combining wood and acrylic. Finally it proposed a new furniture design method that follows the trend by researching new materials with the new concept.

Objectives : This study was done to investigate the formation process of the 'The Spleen controls the blood(脾統血)' concept, to clarify what this concept means and the mechanism of its physiology. Methods : Contents including 'Controlling blood(統血)' and 'Binding blood(攝血)' were searched and analyzed in medical classics. Previous researches were applied. Results & Conclusions : The concept of 'Controlling blood' could be defined as the control of blood movement. This means that it sends blood to where it's needed, and inhibits flow from where it's excessive. 'The Spleen controls the blood' was not used as a physiologic term in early books like Huangdineijing(黃帝內經). It was first used in the 13C, then widely after the 16C. The mechanism of 'Controlling blood' could be classified as the function of 'Production', 'Distribution', and 'Adjustment' of blood. 'Production' of blood can reduce blood fever(血熱) and blood stasis(瘀血), and prevent bleeding. 'Distribution' of blood can reduce the symptoms raised by lack of blood in the five viscera and body. 'Adjustment' of blood means maintaining homeostasis and stability of the human body. Pi can adjust blood flow and prevent blood from being imbalanced.

Numerical analysis was carried out by applying the concept of E-D(expansion-deflection) nozzle to dual bell nozzle. We used the CEA code to calculate the chemical composition of the nozzle and to analyze the freezing flow of 8 species. The turbulence model was chosen as the $k-{\omega}$ SST. We applied the concept of E-D nozzle to the dual bell nozzle and performed the calculated transition altitude and performance. As a result of the interpretation, the application of the E-D nozzle concept led to the formation of over-expansion conditions, which resulted in an increase in the transition altitude.

Purpose: This study aimed to derive a conceptual definition and attributes for nursing students' rights in clinical practice in South Korea. Methods: This concept-analysis study was conducted at a nursing school in South Korea. The participants were recruited using purposive sampling. The inclusion criteria were being a fourth-year nursing student and having two or more semesters of practical experience. The hybrid model used in this study had three stages. First, 12 studies were reviewed during the theoretical stage. Second, 10 in-depth interviews were conducted during the fieldwork stage. Third, in the analytical stage, the concept of nursing students' rights related to clinical practice was defined and the attributes were derived. Results: The analysis established five attributes of nursing students' rights: the right to learn, the right to be protected from infections and accidents, the right to be cared for and supported, the right to be respected, and the right to be recognized as a member of a nursing team. A key theme that emerged from this study was having the right to learn in a safe and supportive environment. Conclusion: It is necessary to develop a measurement tool based on the above five attributes and to verify its effectiveness.

Purpose: This study conducted a concept analysis to clarify the meaning of anxiety in hospitalized patients with infectious diseases who have been placed in isolation. Methods: This study used Walker and Avant's process of concept analysis. Results: Anxiety in hospitalized patients with infectious diseases who have been placed in isolation can be defined by the following attributes: 1) fear, 2) guilt, 3) isolation, 4) discrimination, 5) frustration, 6) shame, and 7) uncertainty. The antecedents of anxiety were as follows: 1) a lack of information about infectious diseases, 2) restrictions of movement, 3) blockage of the social support system, 4) helplessness, and 5) negative biases. The consequences of anxiety were 1) internalized stigma, 2) loss of confidence, 3) lack of social activities and avoidance, 4) insomnia, 5) poor quality of life. Conclusion: The definition and attributes of anxiety identified in this study can be applied to enhance the understanding of anxiety in hospitalized patients with infectious diseases who have been placed in isolation. Systematic suppose should also be provided to reduce anxiety in these patients.

Purpose: Most of the currently used concepts and measurements of social support have been relevant for general population. The main purpose of this study is to conduct the concept analysis of perceived social support(PSS) of family caregivers for people with dementia. Methods: This study adopted the Walker and Avant concept analysis methodology. Results: Findings from this concept analysis suggested four defining attributes of PSS of family caregivers for people with dementia: 1) PSS is help or assistance that family caregivers perceive as available when needed; 2) PSS is offered through socio-ecological structure; 3) PSS has a specific function to meet the needs of family caregivers; and 4) PSS includes quality aspects where family caregivers choose, use, or evaluate it. Borrowing from the socio-ecological model, this study proposed the structural aspects of PSS. This study also identified functional aspects of PSS, such as emotional support, informational support, appraisal support, and practical support. Finally, this study assessed quality aspects of PSS, such as satisfaction, timeliness, usefulness, accessibility, and coordination. Conclusion: Focusing on family caregivers for people with dementia, we proposed a new model of PSS. The present study helped refine and clarify the concept of PSS of family caregivers for people with dementia. The results of this study may also contribute to promoting the development of more effective instruments for the concept.

This study begins with the interests of the problems in learning a region under the Korean National Curriculum in geography field and the perceptions on the region which affects students 'formation of regional concept. The purposes of this study are to find problems in learning a region and to construct a new content for learning a region to improve the current problems. This study suggests that it is necessary for student to establish a clear concept on a region in order to effectively learn a region. Therefore, this study reviews how concepts on a region have changed and selects important elements in learning a region by considering a level of students' understanding. The important elements selected in this study are the definition of a region, the formation of a region, and the system of a region. By learning a real region established as a 'region for instruction' of a medium scale, students can reach an appropriate level of meaningful understanding of a region. This study found that an appropriate selection of scale in choosing the extent of a region was critical in success of effective organization of learning contents.

Appreciating the aspect of modem architecture requires not only the comprehension of the nature of design and architects' ways of thinking and expression but also observers' views on buildings and their perceptive/cognitive stages. This calls for an in-depth study on the "system of phenomenological perceptions" that works as a new architectural experience system. The system of phenomenological perceptions makes it possible to specify the individual process of understanding architecture, that is, hands-on experiences, participations, feelings, perceptions, and cognition. The value of user experience and cognition has been emphasized by philosophical and aesthetical concepts as well. Therefore, in order to better appreciate the modern architecture, this study suggests theoretical consideration to "orientation and event" that are crucial elements in understanding a phenomenological view and materializing actual space formation. This offers the cognitive system with which we analyze modem architecture and comprehensive expressional methods. In other words, this study contemplates the system of phenomenological perceptions from an existential spatial perspective by structurizing the system of the orientation and the event in order to segmentalize users' current locations, potential directions, the relations with spaces, continual vie'wpoints as well as buildings' functions and interior and exterior division. The system of phenomenological perceptions helps understand and systemize modern architecture through a system based on relations between sensation, perception, cognition, sensitivity, and rationality. This creates a new cognitive system employing the concept of the orientation and the event, which is different from a normal cognitive system basing on the sense of vision. When observers appreciate space, they tend to relate the space to a certain event and to remember their experiences in it. During the process, they draw borders of the space in which the event takes place and give shape to their experiences including actions, movements, cognition and sensation. The process leads to the formation of "placeness," and here, the concept of the orientation comes in as the location and the center of the placeness. This study proves that a determined orientation coupled with individual experience and events settles the place ness; detailed elements in the cognitive system have close relations with one another; the orientation, actions, events, and places are the factors that materialize observers' architectural experience.
