An air-burst munition is limited in space, so there is a limit on the size of the fuze and the amount of ammunition. In order to increase a firepower to a target with limited ammunition, it is necessary to concentrate the firepower on the ground instead of the omnidirectional explosion after flying to the target. This paper explores the design and verification of a ground-detection sensor that detects the direction of the ground and determines the flight-distance of an air-burst munition using a single axis geomagnetic sensor. Prior to the design of the ground detection sensor, a geomagnetic sensor model mounted on the spinning air-burst munition is analyzed and a ground-detection algorithm by simplifying this model is designed. A high speed rotating device to simulate a rotation environment is designed and a geomagnetic sensor and a remote-recording system are fabricated to obtain geomagnetic data. The ground detection algorithm is verified by post-processing the acquired geomagnetic data. Taking miniaturization and low-power into consideration, the ground detection sensor is implemented with analog devices and the processor. The output signal of the ground detection sensor rotating at an arbitrary rotation speed of 200 Hz is connected to the LED (Light Emitting Diode) in the high speed rotating device and the ground detection sensor is verified using a high-speed camera.

This study investigated the relationships of the self-regulated learning strategies used in both science and English classes and motivation to academic performance of science-gifted high school students. Participants of this study were 144 freshmen of Korea Science Academy It was found out that the use of self-regulation learning strategies and motivation exerts differential influence on the academic performance of science-gifted students, depending on the subjects they study. Results showed that they used more vigorously in science class those self-regulated strategies which consist of cognition, metacognition, and resource management strategies than in English class. In addition, their motivation level in science class was significantly higher than that in English class. Self-regulated strategies did not explain any variance in physics GPA. Task value among the motivation variables accounted for 2 percent of variance in physics GPA. Metacognition and time and study environment variables explained 8 percent and 15 percent of variance in English GPA, respectively. Self-efficacy in motivation accounted for 30 percent of variance in English GPA, These results were discussed in the light of instruction for science-gifted high students.

GGBFS (Ground Granulated Blast Furnace Slag) is a byproduct with engineering advantages and HVSC (High Volume Slag Concrete) is widely attempted due to active utilization and reduction of eco-load. In the present work, characteristics of drying shrinkage and early-aged behavior are evaluated for the concrete with 65% replacement ratio of GGBFS and 50MPa of design strength. For the work, 3 different mix conditions are considered and several tests including slump flow, compressive strength, drying and autogeneous shrinkage are performed. From the test, OPC 100 mixture without replacement shows higher strength development before 7 days, however the strength reduction in concrete replaced with GGBFS is not significant due to sufficient free water for cement hydration. OPC 100 mixture also shows significant drying shrinkage due to a great autogeneous shrinkage before 3 days. In the concrete with GGBFS replacement, the drying shrinkage behavior is improved due to relatively small deformation by autogeneous shrinkage. The mixture (OPT BS 65) with lower w/b ratio (0.27) and unit content of water ($160kg/m^3$) shows more improved shrinkage behavior than BS 65 mixture which has simple replacement of GGBFS with 0.30 of w/b and $165kg/m^3$ of water unit content.

The purpose of this study was to examine the influence of the self- regulation of paramedics on their job satisfaction and turnover intention. The subjects in this study were 300 paramedics who worked at general and larger hospitals. A survey was conducted for about four months from May 6 to August 30, 2012. As for data analysis, the statistical package SPSS WIN 18.0 was employed to make a frequency analysis, and the reliability of the instrument used was checked. A factor analysis was made, and a correlation analysis was carried out to look for connections between the variables, and a multiple regression analysis was utilized. Concerning the general characteristics of the respondents, many of the respondents were female, in their 20s, unmarried and received junior-college or higher education. Self-regulation had a very close correlation to job satisfaction and turnover intention, and self-regulation affected the subfactors of job satisfaction. Self-regulation exerted an influence on job satisfaction and turnover intention. The findings of the study are expected to suggest how to boost the job satisfaction of paramedics to step up the development of the organization that they belong to.

This paper explains how the exile experience and the writer's consciousness were presented in Namhaemungyeonrok and Bukgwannojeongrok, both written by Yu, Eui-yang in the 18th century. He was banished to Namhae island and Jongseong because of the King Yeongjo's anger. The author composed his writings by presenting historic events and tales related to the places he was passing, and by presenting poems as well. It means that the author tried to understand these places through history and literary works. Moreover he presented in detail, the lives of people living in the places of his exile. It shows how he tried to understand and recognize their lives as they themselves did. In addition, focusing on the relationships and conversations with the people from each place, the author described his life in exile. There are some reasons he presented his exile experience in the ways mentioned above. First, he was a government official and a writer. Second, as the reason for his banishment was not very significant, he felt relaxed more or less. Last, by focusing on his journey and the place of his exile, he was able to forget the agony he was facing to some degree.

The magnetic properties, thermal stability and anti-corrosion properties of $Cr_86Al_14$ spin valves multilayers were studied. It was found that the magnetic properties of $Cr_86Al_14$ spin valves depend on the thickness of antiferromagnetic, ferromagnetic and non-ferromagnetic layers. Exchange coupled field ($H_{ex}$) and magnetoresistance ratio (%) showed the largest value of 20 Oe, 2 % in $glass/Cr_{86}Al_{14}(600 $\AA$)/Ni_{81}Fe_{19}(50$\AA$)/Cu(40 $\AA$)/Ni_{81}Fe_{19}(40 $\AA$)$ spin valves. The $H_{ex}$ MR ratios (%) of CrAl and FeMn spin valves were decreased with increasing annealing temperatures and were lost at 150 $^{\circ}C$, 250 $^{\circ}C$ respectively. Based on these result, it was elucidated that CrAl is more thermally stable than FeMn. It was also shown that there was no change of $H_{ex}$ MR ratios in CrAl, while FeMn was changed and lost 15 days later in corrosion resistance test under 35 $^{\circ}C$, 90 % humidity condition. FeMn was found to be pitted and peeled off 15 days later by SEM micrographic analysis.

As the demand for elderly care service has been on rise due to the increasing of the aging population, the role of visiting caregivers becomes increasingly important. In this context, this study aims to examine whether there are moderating effects of social support and self-efficacy on the relationship between resilience of visiting caregivers and their burnouts. The hierarchical regression analysis was used for statistical analysis. The findings from the study are as follow. First, resilience has a negative effect on burnout. As the resilience increases, the burnout decreases. Second, social support has moderating effects on the relationship between a resilience sub-variable(positivity) and burnout. Third, self-efficacy has a moderating effect on the relationship between a resilience sub-variable(self-regulation) and burnout. The findings of the study suggest that nursing facilities pay attention to psychological characteristics of visiting caregivers as well as their job characteristics in designing burnout prevention programs for them.

This study focuses on the increasing supply and consumption of affair dramas on TV with the theme of unconventional 'infidelity', therefore, is an empirical study that reveals factors related to the problem consciousness of married men and women about infidelity dramas that can affect the sexual socialization of married men and women. This study investigates the effect of married men and women's right to sexual self-determination between couples, personal psychological characteristics (emotional maturity, emotional alienation, self-perception), surrounding environmental characteristics (prevalence of extramarital relationships), and demographic background (gender, age, educational background, economic level) on 'the presence or absence of critical consciousness of infidelity dramas'. For the data of this study, an online survey is conducted on married men and women(614 people), and binary logistic analysis is conducted using SPSS. As a result of this analysis, first, 46% of married men and women have a relatively good level of critical awareness of affair dramas, and overall, the level of critical thinking of married men and women about the infidelity dramas is rather low. Second, there is no significant difference between genders in the perception of problems such as 'excessive beautification of infidelity', 'incitement of infidelity' and 'damage of family values', however, married women are more critical than married men regarding 'explicit sexual description', indicating differences according to gender characteristics. Third, for married men, the level of 'self-perception' and 'marital sexual self-determination right' have a significant effect on the critical mind with infidelity dramas. In the case of married women, it is found that 'the right to sexual self-determination' between married couples and 'emotional alienation' have a significant effect on 'the presence or absence of critical consciousness of infidelity dramas'.
