This paper presents an analysis on driving safety in lane change situation based on road driving data. Autonomous driving is a global trend in vehicle industry. LKAS technologies are already applied in commercial vehicle and researches about lane change maneuver have been actively studied. In autonomous vehicle, not only safety control issue but also imitating human driving maneuver is important. Driving data analysis in lane change situation has been usually dealt with ego vehicle information such as longitudinal acceleration, yaw rate, and steering angle. For this reason, developing safety index according to surrounding vehicle information based on human driving data is needed. In this research, driving data is collected from perception module using LIDAR, radar and RT-GPS sensors. By analyzing human driving pattern in lane change maneuver, safety index that considers both ego vehicle and surrounding vehicle state by using relative velocity and longitudinal clearance has been designed.

Objectives: The purpose of this study is to improve awareness of male dental hygiene by investigating the dentists' perception of male dental hygienists' image and work performance in clinical practice. Methods: The participants were 102 dentists who agreed to participate in this study. They completed- a self-administered questionnaire survey available on a website. The questionnaire comprised 26 questions, with each item scored on a 5-point Likert scale. Results: The male dentists perceived that with an increase in the experience of male dental hygienists would be willing to pay more than for female dental hygienists. In the case of male dentists, male dental hygienists perceived that they would feel stressed in a women-centered work environment. Additionally, it was found that dentists who had experience working with Male dental hygienists responded more positively to work performance awareness than had no experience (p<0.05). Conclusions: Active employment of male dental hygienists in clinical practice, could positively change dentists' perception of male dental hygienists.

In the Relationship between exhibition space and art work in museum, new paradigm has being presented from 1990' s as a turning point. Even if the formal exhibition space that emphasizes itself as a background has currently being continued, the informal exhibition space is coming to the new art museums, especially after 1990's. This study is to understand how the advent of informal form of space in an exhibition of art museum makes a new paradigm in the relation between the exhibition space and art work in conjunction with public's perception after 1990' s that is identified to the time of Pluralism. To do this, the study raised a question on how the public perceive the relation between space and art work through photographs that contain the information on relation between space and art work. And the questionnaire performed through the curators who are working for art museum, students who studies fine art, students who studies design and public who comes to art museum. After survey through this questionnaire, it is made clear that the informal form of space simply has played a role of background since the beginning of art museum. In other hands, the informal form of space that is mainly presented after 1990' s begins to interrupt the public's perception of art work, changing it's meaning through a spatiality.

The purpose of this study is to reduce the group bully phenomenon of mildly mentally retarded(MR) students in middle schools. Video digital contents have been developed and applied to the class. As a result, the normal students' perception of MR students has improved drastically. Especially in the case of students who appeared in the film; their perception has changed a lot more than the students who didn't. Also, the students showed a tendency to recognize the scenes that were produced intentionally by the researcher In conclusion, it is effective to alter a student's attitude through the self-modeling video contents. Particularly, the self-modeling video contents that made by researcher's precise educational goal are more effective on the alteration of the students' perception and behaviors.

The purpose of this study was to examine the developmental changes about self-perception from childhood to adult period. The subjects were 365 of 5th graders in elementary school, the 2nd graders in junior and senior high school, sophomore in college, and adults. The instruments used for this study were Harter's Self-Perception Profile for the children, adolescences, college students, and adults. The results were as follows. 1. From elementary school to junior high school, the score of scholastic, athletic, physical appearance, behavioral conduct, and global self-worth were decreased. At the developmental perspective, the junior high school students were highly anxious for self-perception. 2. Physical appearance were the best predictor of the global self-worth for all developmental stages. 3. Physical appearance, behavioral conduct predicted more about the global self-worth than any other factors for elementary and junior high school students. And for junior high school students, social acceptance and friendship also predicted about the global self-worth. Scholastic competence showed higher correlation with global self-worth for the senior high school and college students than elementary and junior high school students. 4. For college students, males had higer scores than females on ability-oriented but also relationship-oriented subscales. But the adults showed no differences in nurturance, household management, job competence depending on sex.

This study was intended to investigate the influences that consumer's price sensitivity, bundle discount type, and price level of the male cosmetics have on consumer attitude. The design of this research was comprised of $2{\times}2{\times}2$ mixed design studies. The first element was high price sensitivity vs. low sensitivity, the second element was the bundle discount type (mixed leader vs. mixed-joint), and the third element was the price level of male cosmetics (high-price brand vs. low-price brand). The results of this study showed that price sensitivity, bundle discount type and price level of male cosmetic had a statistically significant interaction effect on the consumer's quality perception. The quality perception of low-cost brands for high price sensitivity/mixed-joint bundle group was low. The quality perception of low-cost brands for mixed-leader bundled groups did not change significantly even when the price sensitivity became higher. However, it can be seen as the same result that the overall value is higher when suggested the price information in Mixed-leader bundle than Mixed-joint bundle. In particular, this study suggests that price information should be presented in mixed-leader bundles for high price sensitivity and low cast brands.

This article on environmental noise qualify is concerned with the relationships between the annoyance and perception and sound quality metrics according to exposition time for traffic noise. For invested the characteristics of noise quality, we conducted to the subjective experiments of the annoyance response using the absolute 100 scaling method for the traffic noise sources. The traffic noise sources are composed to varieties exposition time from 15sec to 1200sec. As the results, the first there are decreased the perception loud level for the increase of exposition time with logarithm scale, but increased the annoyance. Second, evaluation index of annoyance is correlated to the loudness(sones), tonality and logarithm scale time with R2=0.83. Also, the composition ratio of traffic noise according to exposition time has the change of range as the logarithm scale ($30{\sim}50%$), tonality($27{\sim}37%$) and loudness($34{\sim}20%$).
