Productivity improvement is one of the important goals which firms' technology developments aim at. Firms' improved productivity from technology development means that their inputs can produce more outputs through technology development, which makes firms' productivity improvement from technology development more and more important in the age of technology advance and convergence like today. This research empirically analyzes the influence of the external technology collaboration network diversity on the productivity improvement of the small and medium-sized enterprises (SMEs) from technology development and the moderating effect of the chief technology officer (CTO)-driven technology development on this influence. This study constructs the research model reflecting the moderating impact of the CTO-driven technology development and tests it with the ordinary least squares regression through the IBM SPSS version 23 by using the 2,000 data about South Korean SMEs. This research empirically reveals two points. One is that SMEs' external technology collaboration network diversity has a positive influence on their productivity improvement from technology development. The other is that the positive effect of SMEs' external technology collaboration network diversity on their productivity improvement from technology development is moderated by the CTO-driven technology development. The two points revealed in this study present two meaningful implications in not only the practical but also academic point of view. The practical implication is that it is effective for SMEs to use CTOs in increasing their productivity improvement from technology development. The academic implication is that making technology collaboration with more diverse external partners can increase SMEs' productivity improvement from technology development.

Cell division in biological education is an important and unintelligible unit. Most of students have no interest in learning the content, and don't concentrate on it because cell division unit contains relatively difficult content. In this vein, during considering the effective learning methods, the researcher found role-play as the method for student's positive access to important and unintelligent learning content. Effect of role-play on their learning achievement of science was analysed through the Chapter of cell division on 3rd grade of middle school students. For this study three levels of middle school students were selected from the school located in Seoul. And divided this students into experiment group and control group by 2 classes respectively. Before putting into practice this instruction, there took into account the before and after of students' learning achievement and their learning attitude by using same questionnaire. On the other hand, the researcher put into practice co-variate analysis by using SPSS statistical package as the measurement method.

This study was done to identify the relationship between emotional labor, self-esteem, and major satisfaction of clinical practice among nursing students. Participants were 199 nursing students who had clinical practice that located in B- city and K- do during the period from August 3rd to 17th, 2015. The average mean scores for self esteem, emotional labor, and major satisfaction were 3.53, 3.26 and 3.46 (5 scale). Pearson's correlation revealed self esteem had a significant positive effect on major satisfaction, while emotional labor had a negative effect on major satisfaction. Factors having a significant influence on major satisfaction included self esteem, satisfaction of college life, and level of academic scores. These factors explained 34.0% of variance in major satisfaction. Thus, the satisfaction of college life, self esteem, and academic score were required to manage for major satisfaction of nursing students.

Digital transformation is about revolutionizing the interaction between virtual and reality. The complex problems that arise in this process must be solved, and one of the methods is computing thinking. Therefore, this study aims to observe whether software education that uses unplugged as liberal education is effective in enhancing computing thinking. For this, 5 elements of computing thinking were extracted and unplugged was applied to liberal software classes, and classes were conducted. During one semester, 16 sessions of classes were conducted and computing thinking enhancement was measured through surveys. As a result, the computing thinking of the students increased overall after classes. Observation surveys showed that, among computing thinking elements, students of all academic fields felt difficulties conceptualizing abstraction elements, those of arts and physical education felt more difficulties with algorithm elements, and those of the humanities felt more difficulties with pattern recognition elements. In the future, various contents for each element should be developed by academic field to aid learner understanding.

The aim of this study was to examine the image for dental hygienists and influence factor in academic high school students. A self-reported questionnaire was surveyed by 211 high school student in G area. the data were analyzed for frequency analysis, average, standard deviation, independent t-test, one-way ANOVA, pearson's correlation coefficient by using SPSS 21.0 program. In case of general high-school students, occupational and business images were higher significantly. The social images were higher significantly in case of having introduction or explanation for dental hygienists. In addition, the self-esteem showed significant differences depending on the oral condition. There were positive correlations among the occupational, business, personal, social images of dental hygienists and self-esteem. Multiple regression analysis showed that highest in occupational images.

Along with developments in technology, National Competency Standards(NCS) education is rising as the new paradigm of change in university education. This study has the purpose of empirically investigating the factors on satisfaction of students before and after application of NCS. The SPSS 22.0 statistics program was applied for the frequency analysis, reliability analysis and t-test. The results and implications by analysis are as follows. First, academic environment and after application of NCS have statistically significant positive influence. Second, From general situation attribute, before application of NCS positively(+) influences regret to university life. It allowed for the developed application of NCS. Third, social satisfaction and after application of NCS were shown to the major variable except long for home characteristics. Through these, this paper suggest to reinforce NCS application. So I recommend that future researches should expand variable samples.

The purpose of this study was to measure the depression level of college students and to analyze the effects of college life stress and circadian rhythm on depression. A questionnaire survey was conducted to 720 students of college in Gwangju area from October 10, 2016 to October 31, and 687 of the collected questionnaires were analyzed. As this result, 34.5% of the students needed treatment for depression, and 71.6% of the students had mild depression. Second, depression was higher in female students, in higher grade students and students living apart from their parents. Third, evening activity type showed higher depression than morning activity type. Fourth, regression analysis revealed that depression was influenced by stress of value problem, circadian rhythm, academic stress, and getting a job stress. The results of this study suggest that students should be able to detect depression early and run a mental health program to relieve college life stress in college. However, this study is limited to some local college students and is not suitable for generalization. It is necessary to conduct research to compare university students and college students in the future.

The purpose of this study is to investigate factors influencing educational performance and mediating effects of learning presence in the university flipped learning classroom. For achieving this purpose, self-regulation, learning presence, and collaborative preference were selected as learner variables, and perceived academic achievement and learning engagement were selected as variables for educational performance. To investigate causal relationships among the variables, 39 university students who took 16 week course flipped-learning class participated self-reported survey. Collected data were analyzed by multiple regression and mediation analyses. The results were as follows: first, learning presence and self-regulation affected learning engagement, and moreover, the learning presence mediated between self-regulation and learning engagement. Second, only learning presence affected perceived academic achievement. Therefore, various strategies for effective flipped learning should be considered, and well-designed classroom activities that can promote learners self-regulation, learning presence, and learning engagement are needed to successful flipped learning.

In this paper, we try to criticize a bias that liberal arts are not practical. First, I introduce holistic models of knowledge and constructivism in education. Second, I suggest 'linguistic turn' as another noticeable phenomenon. Language is an element of culture, but a priviledged one because culture, in itself, is linguistic. So culture is a sort of a text. We can see that liberal arts or humanities to deal with texts, contexts and languages can have an important role to read, understand and construct a world. So the rediscovery of the traditional model of the education of liberal arts like processes of graduating studies of liberal arts or humanities, is relevant to a new 'practical' model of reading and leading recent social transformations. An important point is academic contribution. And current situation called 'Knowledge-Based Society' also supports my point in another way. The situation of rapidly changing knowledge requires an education of problem-solving ability by unifying and reconstructing knowledge supporting with constructivism in education rather than the cramming system of education.
