In Korean society, words related to misogyny are being created and spread out in the Internet communities and the Internet news posts comments. This study was conducted to investigate if exposure to misogynistic words affects misogynistic attitudes toward women. Study 1 examined the relationship between exposure of misogynistic words (the number of misogynistic words known and the level of Internet comments viewed) and explicit misogynistic attitudes. As a result, the greater the exposure of misogynistic words, the less explicit misogynistic attitudes were found among men. The result can be explained as a desensitization of stimuli caused by repetitive exposure to media. In Study 2, experiments were conducted to manipulate the exposure of misogynistic words and to identify the relationship between implicit misogynistic attitudes through implicit association tests. Results of analysis show that implicit misogyny attitude is stronger as male participants are exposed to misogynistic words. The finding of this study suggests that explicit and implicit attitudes toward misogyny can diverge. It also implies that the exposure to misogynistic words can affect men's and women's attitudes in a different manner.

Abortion is prohibited in the Philippines by the law of Christianity. Korean fathers wanted abortions when Filipino mothers were pregnant with their babies (Kopino). However, Filipino mothers had to give birth to the Kopino babies. Therefore, Kopino mothers bring up their babies alone. This study tried to measure and compare what Korean and Filipino evaluate towards Kopino mothers explicitly or implicitly. In addition, this study examined how their attitudes towards Kopino mothers change when the Christianity was primed. As a result of this study, Filipino participants, both explicitly and implicitly, liked more about Kopino mothers than Korean participants. Also, Korean participants showed a little positive explicit attitude and implicit attitude towards Kopino mothers. However, Korean males answered that they liked Kopino mothers at the explicit scale, but they had a negative attitude against Kopino mothers at the implicit level. After activating the Christianity by priming, Filipino participants showed a significant increase of positive attitude towards Kopino mothers at the implicit level. On the other hand, Korean participants remained unaffected. Hence, the priming effect of Christianity varied by country. This study confirmed that Korean females didn't have prejudice against Kopino mothers like Filipino but Korean males had prejudice against them.

Ascent trajectory optimization and explicit guidance problems for a satellite launch vehicle with yaw maneuver in a 3-dimension are considered. The trajectory optimization problem with boundary conditions is formulated as a nonlinear programming problem by parameterizing the inertial pitch and yaw attitude control variables, and is solved by using the SQP algorithm. The flight constraints such as gravity-turn and range safety conditions are imposed. An explicit inertial guidance algorithm in the exoatmospheric phase is also presented. The guidance algorithm provides steering command and time-to-go value directly using the current states of the vehicle and the desired orbit insertion conditions. The liquid propelled Delta 2910 launch vehicle is used as a numerical model.

Lying has been such a wrong act in human society, but at the same time we are perpetrating lying surprisingly often in the interpersonal situation. Like this, between what we think and what we do about telling lie is pretty different, and these differences are came from ambivalent attitudes stemmed from different sources which is divided into the implicit and the explicit attitude. We find manipulative liars by simulated racing task by using virtual environment. Implicit Association Test was applied to them to see implicit beliefs, and used self-reported questionnaires to identify explicit attitude about lying. As a result they could manipulate the explicit measures but could not maneuver their own implicit attraction to lie Liars' deceptive behaviors usually occur in subtle and covert way so that it has been hard to notice and to know what lead them to lie. However, as we know those spontaneous process is linked with deception, triggering them lie, it became no more veiled, unpredictable actions.

In this study, explicit Teaching and Learning strategy for middle school students were developed to improve basic science process skills. After applying these strategy in an actual class, the effects of Teaching and Learning strategy and change of students were analyzed. Explicit Teaching and Learning strategy to improve basic science process skills are developed based on analyzing preceding research. The use of application criteria for class of basic science process skills combined with explicit Teaching and Learning strategy, it is sought for the explicit instructional procedures of said skills. After analyzing the class in which explicit Teaching and Learning strategy were demonstrated, students reported that they were able to comprehend basic science process skills more effectively through the stages of explicit explaining and independent practice. The showing demonstration stage was heavily emphasized by the teacher in this class. Analysis of students' understanding degree about basic science process skills, most of them show positive outcome. Another analysis of ripple effect on daily life and other subjects, it is found that students could have the attitude to make use of science process skills for themselves. Through the result of study, it is found that explicit Teaching and Learning strategy that are developed from this study are an effective way to comprehension students' basic science process skills. Thus, continued study is needed to develop and spread explicit Teaching and Learning strategy of science process skills to be applicable in actual classes in secondary schools.

We present a permanent magnet-based spherical wheel motor that can be used in omnidirectional mobility applications. The proposed motor consists of a ball-shaped rotor with a magnetic dipole and a hemispherical shell with circumferential air-core coils attached to the outer surface acting as a stator. Based on the rotational symmetry of the rotor poles and stator coils, we are able to model the rotor poles and stator coils as dipoles. A simple physical model constructed based on a torque model enables fast numerical simulations of motor dynamics. Based on these numerical simulations, we test various control schemes that enable constant-speed rotation along arbitrary axes with small rotational attitude error. Torque analysis reveals that the back electromotive force induced in the coils can be used to construct a control scheme that achieves the desired results. Numerical simulations of trajectories confirm that even without explicit methods for correcting the rotational attitude error, it is possible to drive the motor with a low attitude error (<5°) using the proposed control scheme.

The purpose of this study was to develop an Implicit Association Test to measure students' gender-biased attitude toward Home Economics, a required subject in middle-school and to examine the effects of gender, gender-biased attitude toward Home Economics, and gender egalitarianism on the perception of the subject. A total of 508 male and female middle-school students were surveyed using Qualtrics. The results revealed that the students had a gender-biased attitude of perceiving Home Economics as feminine as a whole, and this tendency was more evident among female than male students. To the contrary, their attitudes toward Home Economics as a subject was generally favorable when asked explicitly using self-administered questions. Among the high school elective classes, students preferred 'fashion' most, followed by 'dietary life', 'technology and home economics', and 'family life culture'. Female students, students with patriarchal attitude, and students who has gender-biased attitude toward Home Economics were more likely to perceive Home Economics as an alienated and less important subject. The generally positive explicit attitude toward Home Economics may be the results the social desirability effect due to the education. However, the home economists should develop a plan to overcome the gender-biased implicit attitude in order for the value of Home Economics as a subject to be fully addressed.

The present study explores patterns of teachers' corrective feedback and learners' uptake in Korean EFL undergraduate classroom setting. It also examines consistencies and discrepancies in the perception of corrective feedback by teachers and learners. Teachers' and learners' preferences and perception of corrective feedback are further analyzed to determine whether or not those differ from actual practices in English language learning classrooms. The results of the study are as follows. First of all, teachers' corrective feedback type varied according to the learners' error type and English proficiency level. There was a lack of consistency between the teachers' feedback practices and the learners' error types. Second, for the phonological errors, learners' data witnessed the most frequent uptake on recast. For the other error types, however, the learners' uptake rates were high for the explicit corrective feedback. Third, the teachers' explicit knowledge of corrective feedback was rather low and the preferences differed from teacher to teacher. The teachers' feedback perception and preferences did not consistently reflect their actual practices. Finally, patterns of the learners' expectations of corrective feedback varied according to learners' proficiency level. Teachers' and learners' expectations of corrective feedback were also compared and some mismatches were detected.

The purpose of this study was to investigate the effects of a teaching-learning program using the history of science on elementary school students' academic achievement, science attitude, and science process skill. Subjects were 72 students of two groups in the 5th Grade. A experimental group of 36 was instructed 10 lessons in unit of 'our body' using the history of science. The history of science materials used in this program included 4 explicit method, which are Eii, Eij, Eik and Ea type, and 1 implicit method which is I type. The contents validity of this program was reviewed by the science education specialists. The results of the study were as follows: Students of experimental group showed statistically more significant increase in academic achievement and science attitude than control group students. However, there was no significant difference on science process skill between the instruction by applying a teaching-learning program using the history of science and the traditional instruction. Since this program using the history of science is effective for the attitude improvement of elementary school students as well as academic achievement, it is highly likely to be used as the science education material for students with the low affective area.

The purpose of this study was to investigate if a positive psychological-based music therapy program for gambling addicts' families, causes explicit or implicit attitude change towards gambling addicts. The study focused on families with gambling addicts, who use counseling centers for gambling addiction, or participate in GAM-ANON (GA). The experimental group (n=11) participated in 8 sessions of a positive psychology-based group music therapy program, and the control group (n=8) participated in 8 sessions of personal counseling, or GA family gatherings. To confirm treatment effectiveness, the attitude towards the family relationship, was measured by the explicit (Family Relation Scale) and Implicit Association Task (IAT) methods. Additionally, change in emotions including and anger (PANAS, HBDIS), was measured. Results of the study showed that positive emotions increased significantly, in the positive psychotherapy-based music therapy group compared, to the control group. However, in the treatment group with implicit attitudes, the rate of association of negative words with families accelerated significantly, suggesting that gambling addicts' families may have higher negative emotions. For the future, we discussed the necessity of providing a treatment program, that can directly lead to changes in attitudes of family members of gambling addicts.
