The purpose of this study is to identify the best structural model among CEO's entrepreneurship(innovation proactiveness and risk-taking) in small and medium enterprises, group goal orientation(learning and performance goal orientation) and collective efficacy of employees. The result of verifying the best structural model is as follows. First. it indicated that innovation proactiveness of CEO's entrepreneurship positively affected group learning goal orientation and group performance goal orientation of employees while it did not affect risk-taking. Second, it indicated that group learning goal orientation and group performance goal orientation of employees positively affected collective efficacy. Third, it indicated that CEO's innovation proactiveness positively affected collective efficacy through group goal orientation of employees(learning and performance goal orientation). In this study, we targed 162 CEOs and 486 employees in small and medium enterprises located in Seoul, Gyeonggi and Jeju and applied the reponses of employees to 162 enterprises by using the average value measured in three divisions of each enterprise. We conducted a survey as a study method and conducted covariance structure analysis to verify the study model. Implications of the research are as below. First, we provided academic discussions by expanding the study category of goal orientation with an individual level into a group level. Second, we expanded the study category with individual goal orientation and collective efficacy into group goal orientation. Third, we suggested the possibility of another mechanism's effect between entrepreneurship and collective efficacy.

The purpose of this study was to understand the ways to enhance academic help-seeking by analyzing the structural relations among individual(achievement goal orientation) and contextural (teacher behaviors and classroom climate) factors known to affect help-seeking, one of the effective self-regulated learning strategies, for upper elementary students. More specifically, it explored the mediational roles of general classroom climate and student achievement goal orientation in the relation between supportive teacher behaviors and student academic help-seeking. A survey was administered to 315 fifth- or sixth-grade students in three elementary schools and the data from the survey was analyzed. Main results are as follows. First, supportive and learning-oriented teacher behaviors with high expectation related to more cohesive and positive classroom climate and more adaptive achievement goal such as mastery goal. Positive classroom climate played an important role in improving student mastery goal, and only mastery goal among different types of achievement goal orientation had a positive prediction of student help-seeking. Second, teacher behaviors significantly predicted student help-seeking through a double mediation of classroom climate and student mastery goal, which showed that classroom contextual factors and student individual factors interacted for help-seeking. These results suggest that the role of teachers as well as the mastery goal of students are important for enhancing students' help-seeking behavior as an adaptive learning strategy.

Recently target oriented attacks which target an enterprise and a government agency are increasing. The starting point of APT(Advanced Persistent Threat), called as target oriented attacks, is the spear phishing email that is personalized based on the information collected via Internet of the target personnel. It is known that 94% of target oriented attacks use spear phishing emails. Therefore, in this paper, we analysed spear phishing methods in detail and the characteristics and recent trends of spear phishing threats and proposed the effective prevention method of spear phishing for the end user.

This research will target the Dental Hygienics students to identify the level and type of the $2{\times}2$ achievement target orientation, and will study how this achievement target orientation is related to the Self-Regulated Learning, as well as the effect on the each sub elements of the Self-Regulated Learning (SRL). Among the $2{\times}2$ achievement target orientation of all the female university students, the skillful approach was found to be highest. In case of the adjustment of the motivation following grade, intrinsic value of the 1st grader was higher than the intrinsic value of the 2nd and 3rd graders. As for the behavior adjustment, the 3rd grader's time and studying adjustment were found to be higher. Mean while, pursuit of the cooperation was found to be high compared to the time and studying adjustment of the1st and 2nd graders. Second, intrinsic value, overt goal orientation, and studying environment adjustment among the SRL's subelements, manifested significant correlation with all the sub elements of the $2{\times}2$ achievement target orientation. As for the elements that affected cognition adjustment, grade and skillful approach were found to exert significant effect on the performance adjustment. As for the element that affects behavior adjustment, grade and skillful approach exerted significant effect on the sub elements of the behavior adjustment. Analysis on the effect of the achievement target orientation and SRL implies that the direction of the students' learning goal can be modified and that they can learn effectively by using the SRL appropriately. When the two elements are factored in carefully, the key findings could serve as a base data that can motivate the students, inducing effective learning process.

This study explored the structural relationship between achievement goal orientation, learning motivation, and level of interest on the level of flow in distance PBL classes. A structural model was constructed through analysis of previous studies. Data for the verification of the structural model were collected from 59 students in the teaching courses. The study took PBL lessons remotely. After the PBL class was ended, flow, achievement goal orientation, learning motivation, and level of interest were measured. The collected data were analyzed using the structural equation model analysis method. As a result, the structural model proposed in this study was verified to be valid. It was verified that the level of interest mediated the influence of achievement goal orientation and learning motivation to influence commitment. Next, it was verified that the path through which the level of interest mediates the effect of achievement goal orientation has the greatest influence. Therefore, it is possible to suggest that the level of flow can be adjusted if the level of interest is adjusted in consideration of the achievement goal orientation of learners when operating distance PBL classes.
