The study investigated the hygienic practice attitudes of 500 housewives living in the Seoul area through survey. The suey questionnaire evaluated general information, purchasing behaviors, 4 parts of hygienic practice attitude and the associated factors. The subjects were mostly full-time housewives aged in their $30{\sim}40's$, high school graduates from middle-class families who had been married for $6{\sim}10$ years. The mean score for hygienic practice attitude was 2.9 out of 5 point scale, representing a fairly low hygienic practice attitude except for food preparation area(3.4 pt.). Factors affecting hygienic practice attitude were age, occupation, and marriage term. Practice attitude was positively correlated with age (p<0.01). Full-time housewives had better practice attitude. Housewives with <5 and >26 years of marriage showed inferior practice attitude (p<0.05). In addition, food purchasing behaviors were strongly related to hygienic practice attitude. Housewives gathering hygiene information from mass media maintained a significantly higher practice attitude (p<0.05), and so did the housewives focusing on 'nutrition' and 'freshness' when fish and frozen foods were purchased (p<0.05). In contrast, housewives focusing on cost had a significantly lower practice attitude (p<0.05). In conclusion, the level of hygienic practice attitude of housewives was fairly low and was affected by age, occupation status, marriage term and several aspects of purchasing behaviors. Therefore, it is extremely important to conduct training and education for housewives to improve their hygienic practice attitude and awareness of hygiene.

The objective of this study was to evaluate the causal relationships among environmental belief, ambivalence, subjective norm, attitude and meat consumption behavior. A total of 318 questionnaires were completed. A structural equation model was employed to assess the causal effects of constructs. The results of the study demonstrated that the structural analysis results for the data also indicated excellent model fit. The effects of environmental belief, ambivalence, and subjective norm on attitude were statistically significant. The effects of environmental belief, subjective norm and attitude on meat consumption were statistically significant. The effects of attitude on intention were statistically significant. As had been expected, intention exerted a significant effect on meat consumption. Moreover, environmental belief and ambivalence exerted significant indirect effects on meat consumption through attitude. Subjective norm exerted a significant indirect effect on meat consumption through attitude and intention. Subjective norm also exerted a significant indirect effect on intention through attitude. In developing and testing conceptual models which integrate the relationship among behavioral belief, attitude variable, behavioral intention and meat consumption, this study may approach a deeper understanding of the complex relationship among meat consumption behavior-related variables. Greater understanding of the complex relationship among meat consumption behavior-related variables can improve the practical or managerial diagnosis of the problem and opportunities for different marketing strategies including meat production and meat product development and marketing communication.

Purpose - This study verifies the relationship of the authenticity and the fit of CSV activities on brand equity, brand attitude, and purchase intention. The moderating effect by the ethical consumerism was also verified. Research design, data, and methodology - In order to carry out the purpose of this study, 388 survey data were used. Statistic programs, SPSS 18.0 and AMOS 20.0 were used to analyze the data. Results - It was found that the authenticity and the fit of CSV activities had a positive effect on brand equity. However, the fit of CSV activities did not have any positive effect on brand attitude directly. To bring out the optimal brand attitude and purchasing intention from operating the CSV activities, the corporation must recognize the consumers who possess high ethical consumerism and perform suitable marketing strategies. Conclusions - The results of this study show that when establishing positive brand attitude by operating CSV activities, the corporation must put an effort to show the authenticity of the activity. Additionally, to establish brand equity, brand attitude and purchasing intention, corporation must recognize the consumers with high/low ethical consumerism in order to bring out the optimal brand attitude and purchasing intention by operating the CSV activities.

Purpose - Ethical consumption is the action of buying one product over another with an ethical idea in mind. It has gained in popularity since the 1990s with more emphasis being put on the power of consumer actions to create social, economic, and environmental change. Ethical consumption involves boycotts of certain products or brands as well as purchases linked to ethical issues. Cause-related marketing (the buying behavior of ethical consumption) involves a for-profit and non-profit entity teaming up to promote a product at the same time as promoting a social cause. Each time a consumer buys that product, a donation is made by the for-profit entity to the non-profit entity supporting the specific cause. Cause-related marketing has become a tremendously popular type of ethical consumption in recent years owing to its reputation of allowing companies to "do well by doing good." This study examines how consumers' perception of cause and attitude influence their attitude toward a cause-related marketing campaign and attempts to suggest implications for marketers. Research design, data, and methodology - First, this study was designed to examine the consumers' perception factors (cause involvement, attitude for cause, attitude for company and brand familiarity) in order to determine whether these factors have significantly affected consumers' attitude toward a cause-related marketing campaign. Second, this study developed a structural equation model and tested it empirically using survey data from 223 individual respondents. Respondents were undergraduate students in Chungnam. They were shown an existing real campaign message of cause-related marketing, and then filled out a questionnaire. Data were analyzed with SPSS 20.0 and AMOS 17.0 programs. Results - The hypotheses were tested using factor analysis and structural equation modeling. The study's results showed that brand familiarity, attitude to the company and attitude to the cause significantly affected consumers' attitude toward the cause-related marketing campaign and performance. In particular, attitude to the cause was significantly related to attitude and performance of the cause-related marketing campaign. However, the hypothesis about cause involvement was not supported with the results indicating that cause involvement did not affect consumers' attitude toward the cause-related marketing campaign. The findings underline the importance of consumer perceptions of the cause and the company and their attitude to the cause. They point to the importance of individual differences that influence consumer perceptions of the cause, the company and brand familiarity. Also of importance is the consumer's attitude to the cause. Conclusions - The findings suggest some practical implications in designing and implementing cause-related marketing campaigns. It is important to enhance brand familiarity and create a favorable attitude to the company and attitude to the cause before designing cause-related marketing campaigns. The rising popularity of cause-related marketing has been attributed to its potential to cut through advertising clutter. The findings in this study suggest that marketing campaigns supporting a cause make a difference.

This study aims to analyze and compare environmental attitudes of interest groups, including visitors, local residents, Buddhist monks, and staff of the Korea National Park Service in Gayasan National Park. To achieve this purpose, five hypotheses were formulated and tested. While three hypotheses were statistically rejected, two were accepted. In every interest group, the environmental attitude level of women was higher than that of men. Local residents particularly showed statistically significant differences in accordance with occupation. The difference in environmental attitude between visitors and local residents was not statistically significant. Finally, the environmental attitude level between interest groups was divided into three groups. The staff of the Korea National Park Service showed the highest level of environmental attitude, followed by Buddhist monks, and a group of visitors and residents recorded the lowest. However, the average level of environmental attitude of every interest group scored above the mid-point of 3. Therefore, it can be concluded that there exists no difference between or conflicts among interest groups related to strengthening conservation and management policies regarding the protection of Gayasan National Park.

This paper addresses the performance of three different types of attitude control systems for the Quad-rotor UAV to perform the flip maneuver. For this purpose, Quad-rotor UAV's 6-DOF dynamic model is derived, and it was used for designing an attitude controller of the Quad-rotor UAV. Attitude controllers are designed by three different methods. One is the open-loop control system design, another is the PD control system design, and the last method is the sliding mode control system design. Performances of all controllers are tested by 6-DOF simulation. In case of the open-loop control system, control inputs are calculated by the quad-rotor dynamic model and thrust system model that are identified by the thrust test. The 6-DOF realtime simulation environment was constructed in order to verify the performances of attitude controllers.
