The purpose of this study is to investigate relationships among scientific self-efficacy, achievement in science and cognitive self-regulation learning strategy. The subjects were composed of 158 elementary school students. Data of students' self-efficacy related to science and cognitive self-regulation learning strategy measured by questionnaire were analyzed. Science achievement scores were also collected. The results indicated that self-efficacy and cognitive self-regulation learning strategy predicted science scores. The findings showed that cognitive selfregulation learning strategy mediated the relation between self-efficacy and achievement in science. Memory learning strategy, considered a cognitive self-regulation learning strategy, did not mediate the relation between self-efficacy and science scores. The implications of science education to develop students' science achievement in the classroom and the suggestions for future researchers are discussed.

The effect of the composition and the heat treatment on the magnetic and magnetoresistance properties in AgCo alloy films and Fe/AgCo/Fe trilayers prepared by the co-evaporation method were studied. As the alloy film thickness decreases, especially below 50 nm thick, the magnetoresistance decreases and the saturation field increases significantly. The change of the Co content, heat treatment, and deposition of the Fe under/over-layer were effective to prevent the reduction of the and the increasing of the saturation field. For 40 at.%Co sandwiches, the minimum saturation field was obtained in the 20 nm alloy film with 30nm Fe under-over layer annealed at 300 $^{\circ}C$ for 10 min. Its saturation field and the MR ratio were 1.01 kOe 5.16% respectively.

In order to prepare for weakening of the productivity of agriculture due to serious climate change, the researches on promoting the growth of plant are required. Although the method of using magnetic field for improving the growth of plant was introduced, the effective method of imposing the field on the plant have yet to be studied thoroughly in the literatures. In this paper, we investigated the effects of static magnetic field on the growth and the early seed germination of radish sprouts according to the strength, direction of excitation and the expose time of the magnetic field, and present the effective method of imposing magnetic fields. From the measurements, it was found that the radish sprouts exposed in the field shows a rapid germination of about 3~4 days than those which had no field, and in order to the effective growth, the strength of the magnetic field should be properly selected, and the excitation direction of magnetic field has little effect on the radish sprouts growth.

The purpose of this study is to investigate the relationship among self-efficacy, motivation proposed by self-determination theory and academic achievement and to confirm the relative predictive power of motivation variables in predicting 480 middle/high students' achievement. The instruments used in this study were 'Self-efficacy' and 'Self - regulation' scale. The data were analyzed with Pearson correlations and multiple regression (stepwised) analysis. The correlations among self-efficacy, self-determination motivation and academic achievement were significant. The variables among self-determination were correlated to academic achievement in middle school. Among the variables of self-determination motivation, identified regulation, Integrated regulation and intrinsic regulation were positively related to academic achievement in high school but amotivation was negatively related to academic achievement. Self-control efficacy and self-confidence were the significance predictor of academic achievement in middle school. Hard-task preference and self-control efficacy were the significance predictor of academic achievement in high school students. Introjected-regulation was the best predictor of academic achievement in middle school. Identified-regulation was the best predictor of academic achievement in high school.

Self-theories regarding general intelligence and English ability were measured from two countries (Korea and Pakistan) and their relationships with self-reported overall academic achievement and English language achievement were examined. No significant mean differences between the two countries were found regarding college students' self-theories. There were significant mean differences in overall academic achievement and English achievement between the two countries. Both the overall academic achievement and English achievement were significantly correlated with various self-theories while taking both samples together. Achievement measures were predicted by self-theories of general intelligence and English language ability. The current study highlighted the relationship between self-theories about general intelligence and English language ability and their relationship with self-reported achievement in two cultural contexts. This research also introduced new instruments to measure self-theories that can be used in studying self-theories in different domains.

The purpose of this study based on descriptive research is to examine the convergent relationship of interpersonal competence, self-determination motivation and self-regulated learning ability in nursing students. Data collected from 251 nursing students at a university located in C province from June, 2018 to July, 2018 are analyzed using SPSS/WIN 21.0. As a result, there are positive correlation between interpersonal competence(r=.361, p<.001) and self-determination motivation(r=.466, p<.001) and self-regulated-learning-ability. Interpersonal competence and self-determination motivation have not meaningful relationship(r=.091, p=.148). It is turned out that interpersonal competence and self-determination motivation are influenced on the self-regulated learning ability respectively. Based on these results, research should be continued on the developing new educational methods through convergence of factors by analyzing relevant factors to enhance interpersonal competence and self-determination motivation that affect self-regulated learning ability.

This study attempted to verify the structural model of the effects of stress, self-efficacy, and self-control on smartphone addiction in University students. The subjects of this study were 440 University students in G and P city. Results, First the most influential variables on smartphone addiction were self-control, followed by stress, and two variables explained explanation about smartphone addiction in 34%. Second, self-efficacy had a positive effect on self-control and stress had a negative effect. Both variables had an indirect effect on smartphone addiction through self-control. In groups less than 4 hours and above, there was a partial regulation effect because of differences between groups in the smartphone addiction pathway coefficients of stress and self-efficacy. Therefore, in order to reduce smartphone addiction, it is important to find ways to reduce stress and increase self-control and self-efficacy, and necessary to develop various programs and tailor educational interventions for each individual situation.

As dating violence is recently rising as one of the most serious social issues, the study examined the effect of internalized shame on controlling behavior manifested in dating relationship. We explored the mediation effect of self-absorption, indicating maladaptive self-focused attention, between each of the four sub-factors of internalized shame(inadequacy, emptiness, self punishment, and fear of mistake) and controlling behavior. Based on the data obtained from 200 single people in their 20-30s, it was revealed that the internalized shame, the self-absorption, and the controlling behavior in dating relationships were all positively correlated. The mediation effect of self-absorption was significant between the sub-factors of internalized shame (inadequacy, emptiness, self punishment, and fear of mistake) and controlling behavior. In other words, the higher the inadequacy, emptiness, self punishment, and fear of mistake, the bigger the self-absorption, and the more frequent the controlling behavior in dating relationship.
