The purpose of this research is to analyze the effects of lifestyles of senior men in their 50s to 60s on image management behavior. Also, this study investigates the effects of image management behavior on psychological well-being. A total of 300 respondents participated in the survey which targeted senior men in their 50s to 60s. Collected data were used for statistical analysis using SPSS 24. Descriptive statistics, frequency analysis, reliability, factor analysis, regression analysis were conducted. The findings indicated that there were significant effects of lifestyle factors such as pursuit of health, social interaction, and pursuit of materialism on image management behavior. These lifestyle factors positively influenced body/appearance management, beauty/cosmetic surgery management, and clothes/fashion management. However, the pursuit of safety positively influenced clothes/fashion management only. In addition, image management behavior of senior men significantly influenced psychological well-being. Body/appearance management and clothes/fashion management significantly influenced life satisfaction while clothes/fashion management significantly influenced ego achievement. This study may help enterprises in the fashion, beauty and medical industries develop new products for enhancing the image and lifestyle of senior men in their 50s and 60s in an aging society.

Several technology have been investigated to reduce the emissions of 2-stroke motorcycle engines, for example, advanced fuel metering system, improved scavenging characteristic.combustion chamber modification, exhaust gas aftertreatment, etc, <br/> Aftertreatment technology is a cost effective method specially for small 2-stroke motorcycle engine. Catalysts can reduce not only emissions, but also power output, if it has any obstruction to the flow of exhaust gas.<br/> Within this study. a 90cc small 2-stroke engine was used with different types of catalysts. Comparison tests were performed between a hot tube catalyst and a hot tube plus flex coat catalyst. This result demonstrates the effects from both restriction and inside temperature caused by catalysts.

The world emission regulations for motorcycle become increasingly strict recently. In order to comply new legislation, combustion optimization and aftertreatment methods have been used by many researchers for the development of motorcycle. However, aftertreatment method is very popular for the emission reduction in small engines, because product costs in case of combustion optimization method should be high. . We have used SAI system to achieve better emission reduction.<br/> The purpose of this research is to find optimal characteristics of SAI system in small four stroke engine to achieve better emission reduction result<br/>
