  • Purpose: The purpose of the study was to identify the attributes of self-help groups, their antecedents and consequences relating to self-help groups. Methods: We used the Walker and Avant (2010) method using the key word "self-help groups" the Korea Education and Research Information Service (www.riss4u.net), Pubmed, CINAHL and ProQuest for articles on this topic published between January 2000 and March 2013 were searched. Ultimately, 64 domestic and 21 foreign papers were selected for in-depth analysis. Results: The attributes of self-help groups are as follows: 1) members share common experiences and are supportive of each other; 2) members set goals for individual change; 3) groups are self-monitoring; 4) groups learn problem-solving processes through voluntary and active participation; and 5) groups are small and meet regularly. The antecedents of self-help groups are as follows: 1) an intervention by an expert; 2) a diagnosis of their illness; 3) motivation to change individuals' state; and 4) educational desire. The consequences of self-help groups are the relief of symptoms, the improvement of physiological parameters and quality of life, the decrease in depression, stress, and anxiety, the improvement of illness-related knowledge and self-help activity, and a change in beliefs. Conclusion: Self-help groups can be used as an intervention strategy to help people with chronic illness manage their own problems.

  • In this paper, we propose a new concept for error estimation in finite element solutions, which we call mode-based error estimation. The proposed error estimation predicts a posteriori error calculated by the difference between the direct finite element (FE) approximation and the recovered FE approximation. The mode-based FE formulation for the recently developed self-updated finite element is employed to calculate the recovered solution. The formulation is constructed by searching for optimal bending directions for each element, and deep learning is adopted to help find the optimal bending directions. Through various numerical examples using four-node quadrilateral finite elements, we demonstrate the improved predictive capability of the proposed error estimator compared with other competitive methods.

  • In this study, relationships between student the cognitive affective characteristics and conceptual understanding from individual computer-assisted instruction were investigated. Tests regarding field dependence-independence, learning strategy, self-regulated ability, visual learning preference, goal orientation, self-efficacy on ability, and computer attitude were administered. After having been taught by means of a CAl program, a conception test on molecular motion was administered. It was found that student conceptual understanding was significantly related to field independence, learning strategy, self-regulated ability among the cognitive characteristics and visual learning preference, goal orientation, self-efficacy on ability among the affective characteristics. Multiple regression analysis of the cognitive characteristics on conceptual understanding found that field dependence-independence was the most significant predictor. Self-regulated ability and a deep learning strategy were also found to have predictive power. Lastly, analysis of the affective characteristics, visual learning preference and self-efficacy on ability exposed them to be significant predictors of student conceptual understanding.

  • In this study, the analogies on saturated solution generated by elementary school teachers were analyzed in their numbers, materials, and types aspects. The results were also compared with those of general and science-gifted elementary students. A test on the self-generating analogies on the target concept was administered to 111 elementary school teachers, 60 fifth graders at four science-gifted education institutes and 91 fifth graders at three elementary schools. The results revealed that the teachers made more analogies than the general and science-gifted students. In general, both the teachers and the students tended to make the analogies using the materials in family, riding, digestive, and school situations. However, there were a little difference between the teachers and the students in the cases of the analogies using other situations including body/physical activity. Similarly to the cases of the students, the teachers made more functional analogies than structural or structural/functional ones and did more concrete ones than abstract ones. However, they made more verbal, artificial, and enriched analogies than the students. They also made more highly systematic analogies than the general students, and did less ones than the science-gifted students. Educational implications of these findings are discussed.

  • Purpose: This study was conducted to explore the relationships among new nurses' meaning of work, organizational commitment, professional self-image, and retention intention through path analysis. Methods: The participants were 872 nurses with less than a year of clinical experience working at general or tertiary hospitals over 500 beds in Korea. The data were collected using structured questionnaires from May 15, 2021 to June 28, 2021, and analysis was conducted using SPSS/WIN 22.0 and AMOS 21.0 programs. Results: Retention intention was explained by meaning of work, organizational commitment, and professional self-image, its explanatory power was 46.5%. The mediating effect of professional self-image was found on the relationship between meaning of work and retention intention. Conclusion: To encourage the retention intention among new nurses, an environment where new nurses can set a high value on the meaning of work and sense of accomplishment should be created, and a strategy to improve organizational commitment and professional self-image should be established.

  • This study reviewed the literature on the self-distancing method for emotion regulation. Self-distancing refers to taking a step back in dealing with one's own experiences and interpreting them in a relatively objective manner. Studies have indicated that self-distancing affects cognitive and emotional processes, which are particularly beneficial in regulating negative emotions. Therefore, this study focused on organizing previous results to summarize their meaning, assess means of measurement, and analyze possible effects. Above all, the related concepts of an observer's rational perspective and self-reflection were presented to clarify the definition of self-distancing, followed by a discussion of its measurement. Based on this, the effects of self-distancing were introduced according to their emotional, cognitive, physiological, developmental, and behavioral aspects. However, despite repeated verification of the positive effects of self-distancing, there are several inconsistencies that require consideration. Finally, we suggested the study's academic and practical implications and recommended directions for further research.

  • The aim of this investigation was to delineate concepts contributing to the Exercise of Self-Care Agency (E.S.C.A.) Scale developed by Kearney & Fleischer (1979) and to test its construct validity and its predictors. The results are summarized as follows ; 1. By means of principal factor analysis and maximal likelihood factor analysis upon data generated from 280 undergraduate students, the factors of Concern about Health Knowledge, self-Concept, Information - Seeking Behavior, Decision -making and Responsibility, Self-esteem, and Passivity emerged. The total percent of variance explained by the 6 factors was 75.1% 2. To assess factor independence and instrument homogeneity, correlations among the 6 factors were computed. The correlations ranged from .24 to .46 indicating that the factors and the items were not too similar or redundant. 3. Test-retest reliability of the total scale is r=.70. Cronbach's $\alpha$ coefficient for internal consistency of the total scale is .86 and that of the factors ranged from .750 to .661 (only factor 6 .497). 4. In additional analysis of the Exercise of Self-Care Agency Scale in relationship to Multiple Health Locus of Control, Family Environmental Scale, and Cornell Medical Index using stepwise multiple regression, the Internal Health Locus of Control Score predicted 21.8%(F=53.34, p=.0001), Family Environmental Score 8.3%(F=22.59, P=.0001), Modified Cornell Medical Index Score 5.4%(F=15.74, P=.0001) of the score of the E.S.C.A.

  • A variety of NMR techniques were applied to the micro-chemical structural characterization of polyanilines prepared via an efficient synthetic method in a self-stabilized dispersion medium in which the polymerization was conducted in a heterogeneous organic/aqueous biphasic system without any stabilizers. Here, the monomer and growing polymer chain were shown to function simultaneously as a stabilizer, imparting compatibility for the dispersion of the organic phase, and as a form of flexible template in an aqueous reaction medium. Polymerizations predicated on this concept generated polyanilines with a low defect content: solution state $^{13}C-NMR$ and solid $^{13}CDD/CP/MAS$ spectroscopy indicated that the synthesized HCPANi and its soluble derivative, HCPANi-t-BOC, evidenced distinctly different NMR spectra with fewer side peaks, as compared to conventionally prepared PANis, and the complete structural assignments of the observed NMR peaks could be determined via the combination of both 1D and 2D techniques. Ortho-linked defects in HCPANi were estimated to be as low as 7%, as shown by a comparison of the integration of the carbonyl carbon resonance peaks.

  • This study was performed to analyse the tendency of the self-care studies, to investigate the variables related to self-care, which could be applied for the data establishing the theory of self-care. To accomplish the objectives of this study, the researchers analyzed 83 studies available that contained the area of self-care, which was published in local and foreign areas between 1981 and Feb. 1997. The findings of this study are as follows : 1) Studies published in Korea were about twice more than foreign studies. According to the statistics, the number of studies in this study tended to increase year by year. Between 1991 and 1995 were most. Analysis on the subject of those studies showed, that they were most dealt with chronic diseases an adaults. 2) The theoretical definition of self-care were most referred to Orem's self-care. For the main concept of studies, self care performance was the most. 3) The correlational study was most often used design and experimental study is tended to increase. The questionnares were the most often used data collection method. There was lots of different variable measuring technique to evaluate main concepts. 4) In the results of analysis on the propositions related to the self-care performance, a client's education, social support, self-efficacy, and level of knowledge as a causal variable were found. Also, the physiological index improved and quality of life were found to be significant effective variables.
