우리는 유머문서의 추천을 위해서 문서 정보, 사용자 정보, 공통 등급매김 정보 등을 모두 이용하는 4 개의 관찰 변수와 이들간 관계의 학습을 위한 은닉변수를 사용한 확률모델을 구축하였다. 이 모델은 학습된 은닉 변수와 가시 변수 간의 관계를 통해 누락 관찰 데이터에 대해서도 추정값을 유도해 낼 수 있으므로 등급매김 정보가 부족하거나 새로운 사용자와 문서의 도입시에 안정적인 추천 성능을 보여 줄 수가 있다. 또한 확률 모델의 학습을 위해서 EMl 알고리즘을 이용하였는데 저평가된 데이터의 이용도를 높이기 위해서 추천을 반대하는 확률 모델을 따로 두고 이들간에 분류모델(classification model)을 두어서 추정값을 분류해내는 방식을 취한다.

This descriptive research study was undertaken to identify the degree of learning motivation, transfer climate, learning self-efficacy, and transfer motivation, and to correlate the variables, in nursing students receiving simulation-based education. The subjects of this study were 4th grade nursing students who completed a simulation course at a nursing university; data collected using the self-report questionnaire were analyzed using the SPSS 21.0 program. Our results indicate high values of learning motivation, transfer climate (including the lower variables supervisor's support, peer's support, and transfer opportunity), learning self-efficacy, and transfer motivation. Learning motivation, learning self-efficacy, and transfer motivation significantly differed with respect to social motivation for entering school (Z=6.04, p=0.049; Z=6.92, p=0.031; Z=9.16, p=0.010, respectively) and major satisfaction (Z=8.55, p=0.036; Z=12.55, p=0.006; Z=13.47, p=0.004, respectively). All these variables were positively correlated, especially transfer motivation with learning motivation, supervisor's support, peer's support, transfer opportunity, and learning self-efficacy. Taken together, the results of this study indicate a need to develop an effective simulation-based education program to encourage transfer motivation, as well as follow-up studies that verify the causal relationship between transfer motivation and related variables.

Self-efficacy, achievement goals, task value, and attribution are some of the representative motivation constructs that explain adolescents' cognition, affect, and behavioral patterns in achievement settings. These constructs have won researchers' recognition by demonstrating explanatory and predictive utility that transcends various social and cultural milieus learners are exposed to. Korean adolescents' motivation is generally in line with this universal trend and can be described adequately with these constructs. Nonetheless, there also exist a host of indigenous factors that shape these motivation constructs to be uniquely Korean. The purpose of the present article was to explore some of the socio-cultural factors that appear to wield particularly determining effects on Korean adolescents' academic motivation. Review of the relevant literature identified interdependent self-construal, traditional morals of filial piety, familism, educational fervor, academic elitism, and the college entrance system as important cultural, social, and policy-related such factors. Also discussed in this article were the roles of these factors in creating more immediate psychological learning environments for Korean adolescents, such as parent-child relationships, teacher-student relationships, and classroom goal structures.

This study investigates the relationships among learning motivation, learning immersion, and academic achievement in college-level nursing students who give non-face-to-face online lectures. The data for this study were collected using questionnaires given to 147 students attending four-year nursing colleges at two universities. For the data analysis method, descriptive statistics, t-test, ANOVA, the Scheffe test, Pearson's correlation analysis, and multiple regression analysis were used. As a result of the study, the average motivation was 101.29±12.18 points, learning commitment was 72.02±8.03 points, and academic achievement was 31.31±4.06 points. The relationships among learning motivation, learning commitment, and adaptation to college life showed significant positive correlations. In the results of multiple regression analysis, factors influencing the academic achievements of nursing students were found to be learning motivation and learning commitment. Therefore, in order to increase academic achievement in nursing college students, it is necessary to develop a specific strategy to improve learning motivation and to develop various activities and programs to immerse students in learning.

This research examines difference in learning motivation and self-regulated learning according to the general characteristics of the students in hotel and food service related departments at vocational colleges, and subsequently identifies correlation between the two attributes. The research conducted a survey for 300 students in hotel and food service related departments at three vocational colleges in Daegu region, and 267 copies were used for the final analysis. In terms of learning motivation, students in the age between 20 and 24 indicated 'employment after graduation' as the strongest motivation while relatively older students indicated 'joy of learning' as their motivation. It turned out that students who showed strong motivation in terms of 'employment after graduation' and 'fun of college life' acquired more professional certificates. Next, regarding self-regulated learning, female students showed higher ability than male students. Students in higher grade, with older age, and with field practice experience showed more strength in self-regulated learning. Students with higher levels of a cognitive strategy, meta cognition and achievement value acquired more professional certificates. Learning motivation and self-regulated learning showed positive correlation with an exception of 'amotivation' among learning motivations. 'Amotivation' demonstrated negative correlation with all the factors of self-regulated learning ability.

The purpose of this study was to identify the relationship between growth mindset, grit and self-directed learning ability of nursing students and investigate the factors influencing self-directed learning ability in online education. Data were collected through online surveys; subjects were consisted of 194 nursing students from J University in province C. Data were analyzed based on frequency, percentile, mean, Pearson's correlations, and multiple regressions. Self-directed learning ability, mindset, and grit in nursing students showed significant positive correlations with each other. Grit had the strongest influence on nursing students' self-directed learning abilities, followed by satisfaction for major studies, standard of living, interpersonal relations, and growth mindset; these factors accounted for 38.1% of the total variance in self-directed learning abilities among nursing students(Adj. R²=.381, p<.001). Overall self-directed learning ability can be improved by grit, growth mindset enhancement program.

In the era of the 4th industrial revolution, the age of artificial intelligence, the development of ICT technology is having various effects on the online and offline educational environment. The universal access of online education changes the educational paradigm and converts it to a learner-centered service. At the time when a new educational environment is required to change, interest in flip learning is increasing. Even adult learner's online learning needs is also shown very high. The purpose of this study was to investigate how repetitive learning activities through flip learning for middle-aged online learners of K-Cyber University has a relationship and structural relationship between the effects of learning immersion and learning interest on learning satisfaction. Through this study, there is significance in research to suggest direction for learning satisfaction based on flip learning. For further studies, if a model of analysis of various factors that can be measured is specified and applied, it can be used as a research background that can maximize learning satisfaction based on flip learning.

This is a primitive experimental study to find effects of 10 times classwide peer tutoring on academic achievement, self-leadership and interpersonal ability of nursing students. According to the results of Mann-Whitney U and Kruskal-Wallis test using SPSS/WIN 19.0, the motive of admission was the factor affecting the most mean ranks related to general characteristics. There were significant differences between academic achievements, cognitive strategy, and promoting relationships(p<.001; p=.020; p=.040), and there was a positive correlation between self-leadership and interpersonal ability(r=.296, p=.041) in Wilcoxon Signed Ranked test. As results of this study, the classwide peer tutoring could be applied in nursing classes for enhancing students' competence, but the researcher suggests further researches with wider range of subjects and setting control group.
