Fuzzy Formal Concept Analysis (FCA) is a mathematical tool for the effective representation of imprecise and vague knowledge. However, with a large number of formal concepts from a fuzzy context, the task of knowledge representation becomes complex. Hence, knowledge reduction is an important issue in FCA with a fuzzy setting. The purpose of this current study is to address this issue by proposing a method that computes the corresponding crisp order for the fuzzy relation in a given fuzzy formal context. The obtained formal context using the proposed method provides a fewer number of concepts when compared to original fuzzy context. The resultant lattice structure is a reduced form of its corresponding fuzzy concept lattice and preserves the specialized and generalized concepts, as well as stability. This study also shows a step-by-step demonstration of the proposed method and its application.

Purpose: To identify and clarify the concept of labor support. Methods: This study used Schwartz-Barcott & Kim's hybrid model to identify the main attributes and indicators. In the fieldwork stage, data were collected in Seoul and Chenmam, Korea. The participants were five nurses working in the delivery room and four women who delivered more than two children by vaginal delivery. Results: The concept of labor support was found to have nine attributes and 23 indicators in two dimensions. For the physical intervention dimension, five attributes were derived. They were pain relief, selective use of technology, ambulation/positioning, physiological pushing, and increasing comfort. For the labor support practices dimension the attributeswereprovidinginformation, relief and encouragement, family support, and presence. Conclusion: The concept analysis of labor support in this study could provide guidelines for 'labor support' nursing practice and be useful for research in the women's health field.

In this study, in order to analyze the crack retardation behaviors, effective plastic zone concept was proposed. By use of the proposed concept, crack retardation period, compressive residual stress and variation of effective plastic zone shapes were obtained. The results were compared with those of Willenborg model. Retardation period, compressive residual stress and effective plastic zone size obtained by using effective plastic zone concept were larger then the results obtained by using Willenborg analysis. Effective stress intensity factors obtained by using effective plastic zone concept were smaller then the results obtained by using Willenborg analysis.

This study examined the relationships between multiple intelligences as cognitive factors and affective factors of learning motivation and academic self-concept. The data were collected from 276 4th grade elementary school students and analyzed by correlation, multi-variate analysis, and step-wise multiple regression. Results were that (1) multiple intelligences, learning motivation, and academic self-concept had statistically significant correlations among themselves. Multi-variate analysis showed that intra-personal intelligence explained 58.6% of the linear combination of learning motivation and academic self-concept. (2) Intra-personal intelligence explained 29% to 58% of learning motivation and its sub-factors of achievement motivation, internal locus of control, self-efficacy, and self-regulation. (3) Intra-personal intelligence, logical-mathematical intelligence, musical intelligence, and inter-personal intelligence were explanatory variables for academic self-concept and its sub-factors.

The objectives of this paper are to introduce some characteristics of two-dimensional concept of quality and to find out the possibility of the application of two-dimensional quality concept for improving the service quality. The concept was applied to small & medium-sized foreign language Institute. In order to select some service quality dimensions and decide attractive qualify factors among numerous factors, factor analysis and frequently analysis were used. The result. is that all quality factors in empathy dimension are identified as attractive quality factors. This implies that customization program is necessary in small & medium-sized foreign language institutes for improving their competitiveness. However, all quality factors in tangibles dimension are identified as must-be quality factors.

Purpose: The purpose of this study was to explore the concept of Mother-Child Interaction (MCI). Methods: The concept analysis method described by Walker & Avant (2005) was used. Results: The attributes of MCI were as follows; 1) MCI involves positive or negative affective and verbal communication. 2) MCI involves mother, child, and dyadic activity. 3) MCI involves sensitivity, responsiveness, and child developmental stimulation. 4) MCI is reciprocal, goal-oriented partnership process. The antecedents of MCI are need for goal attainment, relationship, and child development (cognitive, physical, emotional, and social). The consequences of MCI are goal attainment, promotion of mother-child relationship, and promotion of child development. Conclusion: MCI is a reciprocal, goal-oriented partnership process and is an important concept in child development and health. Appropriate instruments to operationalize the concept need to be developed.

Purpose: The purpose of this study was to identify and define the concept of cancer rehabilitation in the lives of cancer survivors. Methods: A hybrid model of concept development was used to interface theoretical analaysis and empirical observation with a focus on definition. A comprehensive literature review and semi-structured interviews with five cancer survivors were completed. Results: The concept of cancer rehabilitation was found to be a route toward a positive experience having meaning in two dimensions: recovery of the activities of daily living and intrapersonal growth. Four attributes and ten indicators were defined. Conclusion: Cancer rehabilitation was defined as a positive process of change through recovery of the activities of daily living and intrapersonal growth. Therefore, oncology nurses can be encouraged to design, implement, and evaluate cancer rehabilitation nursing interventions with the results of this study. Further research needs to develop cancer rehabilitation measurements.

Purpose: This study was done to analyze and clarify the concept of empathy in nursing. Methods: Using the concept analysis framework of Walker & Avant 68 articles about empathy were selected for this study. Results: Defining attributes of empathy included recognizing others' perspective and thought, understanding others' emotion, and communicating with them. The antecedents of empathy included contact with patients, respect and trust for patients, a certain level of cognitive ability, and communication skills. Consequences of empathy were increasing patient self-understanding, self-awareness as a therapeutic subject and improving quality of nursing. The concept was clarified through presentation of model, borderline, related, and contrary cases. Conclusion: The results of this study are meaningful in that the concept and attributes of empathy are explored in the area of nursing. Also, based on results of this study, development of standardized tools to measure patient-perceived empathy and measure the three attributes of empathy is recommended as well as the development of educational programs to enhance empathy.

The purpose of this study is to compare the elementary science curriculum and textbooks of Korea, the United States, Japan, and Singapore to know how the contents on particulate concept of matter is introduced and expressed. In Korea, particulate concept of matter was adopted as a term for 'molecules' in the 3rd through 6th curriculum, and the term for 'particles' was adopted in the 2009 revised curriculum. In the United States, NGSS adopted the term 'particle' in fifth grade. Japan presented the concept of 'particle' as a core concept of matter in the commentary, and the expressions 'particles' were being introduced in the textbooks. But it did not cover particulate nature of matter at the elementary school level in Singapore. An analysis of elementary textbooks in Korea, the United States and Japan except Singapore showed particulate expressions in 'dissolution', 'state change of water', 'gas pressure and volume', 'combustion and extinguishment' units. Korean textbook was only being introduced in 'dissolution' and 'gas pressure and volume', but in the textbooks of Japan and the United States, water was expressed as particles in 'state change of water' unit. Discussion and implication on the introduction of particulate concept to elementary science curriculum and textbooks were suggested based on the results.

Purpose: This study explored the relationships of maturity fears and appearance interest(interest in appearance, interest in weight) with self-concept among girls with precocious puberty. Methods: The participants for this study were 120 elementary school students (8 to 10 years old) and their parents from two hospitals located in Chungcheong Province. Data were collected from January to February 2019 using self-reported questionnaires. The collected data were analyzed using descriptive statistics, the independent t-test, the Mann-Whitney U test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis in SPSS for Windows version 23.0. Results: Statistically significant negative correlations were found between self-concept and maturity fears (r=-.34, p<.001) and interest in weight (r=-.29, p=.001). Maturity fears were identified as a factor affecting the self-concept of girls with precocious puberty (β=-.34, p<.001). This variable explained 11.5% of the variance in the self-concept of girls who experienced precocious puberty. Conclusion: This study confirmed that maturity fears had a major influence on self-concept in girls with precocious puberty. The results of this study can be used as basic data for the development of a psychosocial nursing intervention program for girls who experience precocious puberty.
