Purpose: To determine the mediating as well as moderating effect on both the emotional labor and burnout of professional self-concept perspective organ transplantation coordinators (OTC)'. Method: A self-report questionnaire was collected from 86 OTCs nationwide. The data were analyzed using t-test, ANOVA, Scheffe' test, Pearson' Correlation Coefficients, AMOS 20.0, and multiple regression. Results: For effects of professional self-concept on emotional labor and burnout, higher emotional labor was related to higher burnout. When professional self-concept was mediated, emotional labor had a greater effect on burnout however, a partial mediating effect was detected. From the regression analysis with the independent variables of emotional labor (A) and professional self-concept (B), adding relation of both variables ($A{\times}B$) increased the explained variance to 56.3% ($p$<.05). It was confirmed that professional self-concept had a moderating effect on emotional labor and burnout. Conclusion: The results of this study indicate that, when professional self-concept was mediated emotional labor of an OTC decreased, and burnout decreased when professional self-concept was high. Also, by controlling professional self-concept, emotional labor and burnout decreased. Therefore, it's necessary to map out the environment and develop strategies to reduce emotional labor and burnout in organ transplantation coordinators.

This study was to inquire the effectiveness of concept mapping on the learning of biology concept. In this study the achivement acquired by the students in the classes of individual concept mapping and cooperative concept mapping were compared with those of traditional lecture on "photosynthesis and plant respiration". The concept mapping teaching methods, by individuals and groups. were more effective than traditional one. The results of analysis of covariance (ANCOVA) showed that these difference were statistically significant; individual concept mapping was more effective than traditional class result(p<.008). Also the cooperative concept mapping was effective than traditional class result(p<.0001). And the cooperative concept mapping was more effective than the individual one(p<.04). So that cooperative concept mapping is the most effective method in biology class.

In a previous study we proceeded to the remodularization architecture based on classes and packages using the Formal Concept Analysis (FCA)[13] [14] [30]. we then got two possible remodularized architectures and we explored the issue of redistributing classes of a package to other packages, we used an approach based on Oriented Graph to determine the packages that receive the redistributed classes and we evaluated the quality of a remodularized software architecture by metrics [31] [28] [29]. In this paper, we will address the issue of the efficiency of the Oriented Graph in the remodularization of software architectures compared to the Formal Concept Analysis FCA method. The formal method of FCA concept is not popularized among scientists as opposed to the use of the labeled directed graph. It is for this reason that our directed graph approach is more effective in its simplicity and popularity.

In the era marked by information inundation, social network analysis is the most important part of big data analysis, with clique detection being a key technology in social network mining. Also, detecting maximal balance clique in signed networks with positive and negative relationships is essential. In this paper, we present two algorithms. The first one is an algorithm, MCDA1, that detects the maximal balance clique using the improved three-way concept lattice algorithm and object-induced three-way concept lattice (OE-concept). The second one is an improved formal concept analysis algorithm, MCDA2, that improves the efficiency of memory. Additionally, we tested the execution time of our proposed method with four real-world datasets.

This article presents a concept analysis of the gratitude experience of diseased patients. The Rodgers' Evolutionary Method was used for conducting the analysis. A search of CINAHL, MEDLINE, PsycARTICLES, and Springer databases was conducted using "gratitude or appreciation or thanks" and "patient or illness" as a key word, 22 final articles were selected. Three critical attributes of gratitude in patients were identified: positive emotions, acceptance of the current status, and a driving force to plant the will of life. In addition, two antecedents of gratitude in patients were identified: interactions with people or the environment, and the perception of a favorable stimuli or help. Two consequences of gratitude in patients were identified: an increased compliance in implemented treatment, and an enhancement of trust relationship. The concept analysis describes diseased patients' gratitude. This paper will become the basis for future clinical research related to diseased patients' gratitude.

In this study, among the cognitive learning models for information process, Taba’s inductive thinking model and Joyce&Weil’s concept attainment model, which help to obtain and study the concepts, can be applied to the ranges of consumer-education. Considering this, a new teaching-paln can be made. Applying the plan to the present teaching environments. I will do the research possibilities of applying the concept-learning teaching-plan to the consumer education. In the method of this research, many books, related to home economics & consumer-education, characters of concept-learning, and concept teaching-learning models, were studied. Also, on the basis of theoretical evidence, the teaching-plan, that apply the concept teaching model, were made. In addition, experimental research was done to find out the possibilities that the plan focusing on concept learning was applied or not. As a result of this study, two points are briefly summarized : 1. The teaching plan using Taba’s and Joyce & Weil’s concept-attainment model was made. 2. Concept-learning in consumer-education didn’t have a great a great influence to the changes of consumer-roles and attitudes, but had a great influence to the effects of consumer concept-knowledge(p<0.01) The effects of consumer-knowledge had much relation to consumer-roles and attitudes. The learners whose grade is higher in attainments of consumer-knowledge, also have a high grade in consumer-roles and attitudes.

Almost all buildings/infrastructures made of composite materials are fabricated without proper design. Unlike airplane or automobile parts, prototype test is impossible. One cannot destroy 10 story buildings or 100-meter long bridges. People try to build 100-story buildings or several thousand meter long bridges. In order to realize "composites in construction", the following subjects must be studied in detail, for his design. Concept optimization, Simple method of analysis, Folded plate theory, Size effects in failure, and Critical frequency. Unlike the design procedure with conventional materials, his design should include material design, selection of manufacturing methods, and quality control methods, in addition to the fabrication method. In this paper, concept optimization and folded plate theory are presented for practicing engineers.engineers.

Although the concept of usability has been well defined in the software usability engineering area, it is not appropriate to apply the same concept directly to the consumer electronic products. A new concept of usability appropriate for evaluating consumer electronic consumer electronic products was suggested in this study. It is characterized by integrating both the performance and the impression factors. Based on the concept developed, a systematic and integrated methodology for usability evaluation was proposed. The methodology contains four major steps; the development of the measurement methods for evaluating usability attributes, the development of the analysis techniques for the human interface elements, the development of the evaluation method for the usability of human interface elements, and the development of the usability model. The results of this study can be applied to evaluate the usability of various electonic products in a systematic and efficent manner.

Variable concept plays a crucial role in understanding not only algebra itself but also school mathematics which is algebra-oriented. It solves as an essential means in applying mathematics to the real world because il enables us to describe varying phenomena in the real world. In this study, we examined some matters related to the learning of variable concept in school mathematics. In Particular, we discussed on the teaching of variable concept in the [7-first] stage of the 7th Mathematics Curriculum. We analysed the textbooks in the [7-first] stage and attempted to explain concretely the contents and teaching methods of variable concept which be taught in school mathematics. After reconsidering the practices on variable concept teaching, we pointed out the problems of formalistic teaching method and then proposed the direction in which variable concept teaching should go.

Integration of CAM and CAM information is important in the CIM era. For a CIM system, the feature representation can be a solution to the integration of product model data. These are geometry feature, functional feature, and manufacturing feature in the feature context. This paper proposes a framework to integrate the configuration design method, parametric modeling and the feature modeling method. The concept of design unit which is one level higher than functional feature and parametric modeling concept with functional features have been proposed.
