This study was designed to classify the parents' and their children's perception of contact frequency and to examine differences between career development competency and academic outcomes according to perceptional differences. Data of elementary school to high school students from the School Career Education Survey (2018) were used, and latent profile analysis (LPA) was utilized to explore the parents' and their children's perception of contact frequency. The perception of parents' and their children's contact frequency was classified into six groups in elementary and middle school and seven groups in high school. Career development competency (self-understanding and social competence, job understanding, career exploration, and career design and reparation) and academic outcomes (autonomous learning, motivation, and self-directed learning) of classified groups related to contact frequency significantly differed. In general, groups who reported a higher perception of contact frequency by children than parents showed higher vocational identity and better academic outcomes. This result implies that perceived contact frequency between parents and children can differ by school level, and its differences can be related to career development competency and academic outcomes of adolescents.

Purpose of study: The purpose of this study is to explore the moderating effect of learning motivation in the effect of cognitive presence on cognitive regulation. Research content and method: The subjects of this study were 160 preservice teachers who are enrolled in the Faculty of Education of a university. The survey measured cognitive control, human presence, and learning motivation. Among the collected data, learning motivation was averaged. In addition, a group with low learning motivation and a group with high motivation were distinguished. Next, this study compared the averages of cognitive control by classifying the learning motivation levels. The collected data was analyzed using a multiple regression (Stepwise) method to explore the effect of cognitive presence on cognitive control. First, multiple regression analysis was performed on the entire group. Second, multiple regression analysis was performed by dividing the group with low learning motivation from the group with high motivation. Conclusions and Suggestions: As a result of the analysis, the group with high learning motivation showed a higher level of cognitive control than the group with low motivation. In the group with high learning motivation, only content understanding among the sub-factors of cognitive presence had an effect on cognitive control. In the group with low learning motivation, all factors of cognitive presence were affected.

In the ad-hoc mode of IEEE 802.11 standard, beacon is used for power control and network alarming between each node, and also it is for the synchronization in controlling network as PCF. However beacon is also used to inform the neighbor nodes of itself except for original purpose in the environment of IEEE 802.11s. For this, the existing beacon's transmission mechanism can't perform a function in full. In this paper, we suggest much faster neighbor discovery reducing network congestion caused by beacon through modification of beacon transmission mechanism. And we will show that suggesting algorithm more faster full neighbor discovery than traditional neighbor discovery using for IEEE 802.11 through simulation and test in real ad-hoc network.

This study verified the reliability and validity of the Korean version of the Student Career Construct Inventory(K-SCCI) that was translated into Korean language from the Student Career Construct Inventory (SCCI) developed by Savickas et al.(2018). To achieve this, this study conducted item content analysis, exploratory factor analysis, confirmatory factor analysis, and criterion-related validity in 530 university students. As a result of item content analysis and exploratory factor analysis, it was found that 4 factor models and 18 items were the most appropriate in K-SCCI. The 4 factors were named as crystallizing a vocational self-concept, exploring to gather information about occupations, deciding to commit to an occupational choic, and preparing to implement that choice. As a result of confirmatory factor analysis to verify the goodness-of-fit of the 4 factor models, it appeared to be appropriate. As a result of analyzing the correlation with related measures to verify the criterion-related validity of measures, it was found that student career construct was negatively correlated with employment anxiety but positively correlated with career adaptability.

Precision guidance filter design for a tactical missile with a strapdown seeker aided by low-cost strapdown sensors has been addressed in this paper. The low-cost strapdown sensors consist of an IMU with 3-axis accelerometers and gyroscopes, 3-axis magnetometers, and a barometer. Missile's position, velocity, attitude, and bias error of the barometer are considered as state variables. Since the state and measurement equations are highly nonlinear, we adopt UKF(Unscented Kalman Filter). The proposed guidance filter has a function of a navigation filter if target position error is not considered. In the case that the target position error is introduced, the proposed filter can effectively estimate the relative states of the missile to the true target. For specific engagement scenarios, we can observe that observability problems occur.
