The purpose of this study was to analyze the effectiveness of negative appeal ads taking social problems as their themes. Two social problem ad themes concerning abortion and drug addiction were selected as stimulus. Questionnaires consisted of questions about affective response cognitive evaluation consumer's characteristics(sex, clothing involvement social problem involvement) and the ad and brand attitudes They were distributed to 200 high school students in Seoul. Results were : 1 The affective response consisted of 4 dimensions(negative inactivating activating positive) and the cognitive evaluation had 3 dimensions(utility·persuasive power creativity awareness) 2. Creativity and awareness dimensions and the ad attitude had positive influence on the brand attitude for the abortion theme ad,. Creativity dimension and consumer's clothing involvement had positive influence on the brand attitude for the drug addiction theme ad . Especially the affective response had no significant influence on the brand attitude. This result suggests that in case of negative appeal ads the affective response does not necessarily degrade the brand attitude while positive cognitive evaluation on creativity and awareness of the could influence the brand attitude favorably through raising attention to the brand resulting in high effectiveness of the ad.

In this paper, we introduce a concept of HEMP systems and analyze a shielding effectiveness by varying placements of the antenna elements. Maxwell's equations for the high frequency of the EMP is represented in the LOS. In order to investigate the effects of electromagnetic attenuations, a shielding room was constructed and employed to obtain measured data. Shielding effects were measured by changing frequency and the distance of receiving antenna. Each measured value was compared to U.S. standard and measuring method was simplified. shielding effects were measured by three different conditions of shielding room. Find the difference between forward measurement and reverse measurement and factors which affects the measurement in shielding room.

PURPOSES : Traffic congestions which occur in the intersections of arterials lead to mobility and environment problem, and then traffic agencies and engineers have been struggling for mitigating congestions with greenhouse gas emissions. As an alternative of solving theses problems, this study is to introduce a low-cost and high-effectiveness countermeasure as unconventional intersections which are successfully in operation in U.S.. The main feature of unconventional intersections is to reroute turning movement on an approach to other approach, which consequently more green time is available for the progression of through traffic. Due to improved progression, this unique geometric design contributes to reduce delays with greenhouse gas emission and provides a viable alternative to interchanges. This study is to evaluate the potential operation and environment benefits of unconventional intersections. METHODS : This study used the VISSIM model with Synchro and EnViVer. Synchro is to optimize signal phases and EnViVer model to estimate the amount of greenhouse gas emissions by each condition. RESULTS : The result shows that unconventional intersections lead to increase the capacity and to reduce greenhouse gas emissions, compared to existing intersections. CONCLUSIONS : Unconventional intersections have the ability to positively impact operations and environments as a low-cost and high-effectiveness countermeasure.

The purpose of his study was to investigate the effectiveness on clothing advertisement of three types of model, perception of model attributes by the clothing consumers, and difference in advertisement effectiveness according to perception of model attributes. Three types of advertisements for easy casual brand were selected, which are using celebrity, expert and general consumer models. The final analysis included 304 persons, who ranged from 16 to 25 in age. The statistics used analysis include ANOVA, Duncan's multiple range test, factor analysis and regression by the SPSS program. The result were as follow:1. The celebrity advertisement was the most effective type on all kinds of attitude changes (cognitive, emotional, and behavioral attitude changes) of consumers.2. The celebrity model received high scores on attractiveness and truthfulness; and the general consumer model received high scores on truthfulness and similarity.3. The amount of consumers attitude changes was different according to the perceptions of model attributes as well as the types of model.

This is a thesis about the experiment of comparison characteristic of power and exhaust gas in the same condition between diesel engine that is equipped turbocharger different from response power to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment with natural aspiration diesel engine and turbocharger diesel engine, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is much higher than the other one. In other hand, in exhaust gas experiment, turbocharger model exhausts more $NO_X$ and $O_2$, but it doesn't significantly affect the result when it comes with decreasing of $CO_2$ and effectiveness of increased power characteristic. As a result, the turbocharger diesel engine is economically effective comparing with the natural aspiration diesel engine.

An evaluation in school education systems should identify what students achieve and what they do not. Since 2010, if the health education curriculum is provided as a selective course in middle and high school settings, the national health education standards are required because these affect on students' applications of a higher stage of education. It would be better that each school follows their autonomy to evaluate each student's achievement on the health education. In addition, the national health education standards should be set to assess the effectiveness of seven categories in health education. It is hard to achieve good results through 17 hours of the health education per a semester. Therefore, the health education would be better to provide more than 50 hours per a semester, and the 3th graders instead of 5th graders are suitable for taking the health education because they are more flexible to change their lifestyle toward healthier life. There are two categories in the health education, such as "Mental Health" and "Society and Health" which are expanded from originally seven categories of the health education. Moreover, professional training programs for school nurses should be provided because these two categories are relatively a new domain for them. Finally, all elementary middle and high schools have a school nurse to decrease inequal opportunities of the health education between urban and rural area. When these suggestions are all set in school systems, our students' health behaviors will be improved as well as the effectiveness of the health education.

Background: In occupational studies, it is a known situation that technical and organizational attempts are used to prevent occupational accidents. Especially in the mining sector, if these attempts cannot prevent occupational accidents, personal protective equipment (PPE) becomes a necessity. Thus, in this study, the main objective is to examine the effects of the variables on the use of PPE and identify important factors. Methods: A questionnaire was implemented and structural equation modeling was conducted to ascertain the significant factors affecting the PPE use of mining employees. The model includes the factors that ergonomics, the efficiency of PPE and employee training, and PPE usage habit. Results: The results indicate that ergonomics and employee training have no significant effect (p > 0.05) on the use of PPE. The efficiency of PPE has a statistically meaningful effect (p < 0.05) on the use of PPE. Various variables have been evaluated in previous studies. However, none of them examined the variables simultaneously. Conclusion: The developed model in the study enables to better focus on ergonomics and employee training in the PPE usage. The effectiveness of a PPE makes its use unavoidable. Emphasizing PPE effectiveness in OHS training and even showing them in practice will increase employees' PPE usage. The fact that a PPE with high effectiveness is also ergonomic means that it will be used at high rates by the employee.
