Purpose: Compliance in kidney transplant recipients is critical for a positive prognosis. Especially compliance with medications after kidney transplantation is a major health care issue with implications for graft rejection and graft loss. But the definition of compliance in transplantation varies among centers. The purpose of this study was to clarify the concept of compliance in kidney transplant recipients. Methods: A literature search was conducted using RISS, MEDLINE, CINAHL. The concept analysis was guided by the methodology posited by Walker and Avant. Results: In this study, we found the attributes of the concept: 'compliance with immunosuppressive medication', 'compliance with follow-up', 'compliance with early detection of graft rejection and complication', and 'compliance with prevention of complication'. The antecedents of 'compliance in kidney transplant recipients' included 'having a kidney transplant surgery' and 'normal function of transplanted kidney'. The consequences of 'compliance in kidney transplant recipients' included 'affecting the function of the transplanted kidney' and 'affecting the health of kidney transplant recipients. Conclusion: This study may contribute to the development of tools for measuring compliance in kidney transplant recipients, as well as benefit nursing interventions research to increase compliance in kidney transplant recipients.

This research is an analysis of communication that occurs during the quadratic function teaching and learning process of middle school students, which reflects mathematical modeling. For an in-depth analysis of the communication, Sfard(2008)'s discourse theory and language analysis framework were applied. A quadratic function mathematical modeling teaching and learning were conducted for the week second (1 hour) in June 2019 for students who studied the concept of a quadratic function and who passed a specified period (3 months). The results are as follows. First, The commo-gnitive conflict occurred because of differences in prior knowledge other than quadratic function among students. Second, in the course of communication, knowledge was expanded through problem-solving from different perspectives. These results can be interpreted as allowing students to clearly reveal problems in the communication process based on their understanding of the concept of quadratic functions and to facilitate cooperation among students. of the concept of quadratic functions and to facilitate cooperation among students.

The main objectives of this study were to investigate the concept of family function from the perspective of the contemporary Korean family, and to construct model of change of family function with chronic illness. The hybrid model approach was applied in which three phases(theoretical phase, empirical phase, and analytic phase) of concept development were explored for family functioning. The study was conducted from 1997 to 1998. In empirical phase, two groups of purposive samples were drawn : normal family group composed of six families without ill family member, and ill family group composed of seven families of which wives have rheumatoid arthritis. Only families with child(or children) in primary or secondary schools were included in the study. The results were as follows : In theoretical phase, six dimensions of family concept were emerged : affective, structural, control, cognitive, financial, and reproductive dimension. In order to analyse the Korean normal family function in middle class with middle-aged women, financial and reproductive dimension were not included. In empirical phase, five dimensions(affective, structural, control, cognitive, and external relationship) were found from the normal family data. External relationship dimension is very important factor as a resource of the support, especially when their parents or siblings had no help or support to them. In the affective dimension, Korean family emphasized harmony and balance rather than affective expression between couples and between parents and children. They also showed common goals of the families to solve their problems to control the family members. The priority of the goals was getting into the higher education of their children or helping their unhealthy parents or family members. Six dimensions (affective, structural, control, cognitive, external relationship, and financial) of family functions were emerged from the ill family data. From the analysis of ill family data, types of restructuring house chore after wives illness were developed : (a) negociated, (b) accomodated, and (c) isolated, enduring types. Although the dimensions of family functioning identified in this study are similar to the conceptualizations that exist in the western literature, there were distinct differences in the nature of major themes and subconcepts under these family function dimensions.

One of the most important objectives in science education is to develop students' science literacy. The purpose of this study is to analyze the relevance between biology instructional objectives in the 7th curriculum taught in elementary and secondary schools. For this study, 7 major parts in each grade were analyzed including cell, the form and function of plants, the form and function of animals, genetics, diversity, evolution, ecology, and environment. The strand map of instructional objectives is completed that represents the relation between the objectives. The summary of the results from this study is as follows. First, the concept about cells is not fully covered in lower grades including elementary schools. While the concept of energy metabolism is repeatedly covered, there is no concept of energy covered in learning the concept of energy metabolism in elementary schools. Second, the textbooks in elementary and middle schools have main concepts about the form and function of plants while those in high schools don't. The concept related to the part of the form and function of animals is repeatedly involved in the curriculum throughout the elementary, middle, and high schools. Third, the concepts such as genetics and evolution are involved in higher grades since these concepts are abstract ones. The part of genetics and evolution as well as diversity has no connection between grades in schools, so the development of "notion between" is necessary to relate these concepts with each other. Fourth, the 4 parts of diversity, ecology and environment, evolution, and the form and function of plants are covered in limited grade levels. The results of the relevance of gene in lesson goals will play an important rein as the primary material in developing the connection between textbooks in which lesson goals are closely related to each other throughout all grade levels in elementary, middle and high schools.

In this thesis was conducted to propose a method for efficient information retrieval using concept lattices. Since this thesis designed a new system based on ordinary concept lattices, it has the same approach method as ontology, but this thesis proposes new concept lattices to be used by establishing collaborative relations between objects and concepts that users are likely to search information more efficiently. The system suggested by this thesis can be summarized as below. Firstly, this system leads to a collaborative search by using Three kinds of concepts, such as keyword concept lattices, which focus on input key words, expert concept lattices recommended by experts and theme concept lattices, and based on these 3 concept lattices, it will help users search information they want more efficiently. Besides, as the expert concept and the keyword concept become combined, further providing users with the frequency of keyword and the frequency of category, this system can function to recommend key words related to search words entered by users. Another function of this system is to inform users of key words and categories used in users' interested themes by using the theme concept lattices. Secondly, when there is not keyword entered by a user, it is possible for users to achieve the goal of search through the secondary search when this system provides them with key words related to the input keyword. Thirdly, since most of the information is managed while being dispersed, such dispersed and managed information not only has different expression methods but changes as time goes. Accordingly, By using XMDR for efficient data access and integration of distributed information, this thesis proposes a new technique and retrieval system to integrate dispersed data.

Quality function deployment is an interdisciplinary team process of listening to customers to learn exactly what they want, and then using a logical system to determine how best to fulfill those needs with available resources. It is examined how to extend quality function deployment in this paper. The Pugh concept selection method, ACE(Attribute Categorization and Evaluation) Matrix, and an inventive problem solving method called TRIZ are discussed in relation with quality function deployment.
