¡@¡@The study was undertook the engineers who involved in speed dating from technology industries, in an attempt to understand the masculinities and lifestyles shaped by workplace how to influence engineers from the workplace to speed dating domain, as well as the establishment of heterosexual relationships and management of intimate relationships. The researcher took masculinities as a way to analysis, from the male power and masculinities of the organization as a starting point, by interviewed with engineers to understand how the workplace shaped particular masculinities qualities in the organizations power, control, decision-making and payments. ¡@¡@In Taiwan, the high-tech industrial¡¦s engineers defined as the representatives of hegemonic masculinity by Connell (1995), they enjoyed a privileged position of cultural dominance as well as the relationships of gender order. Also, their professional identity was considered to be welcomed in the marriage market. The study¡¦s interviewers was based on engineers who has been participated in a speed dating activities, and found that engineers were lack of the ability to do intimate, and not good at dominant the topic. Therefore, they have to memorize a joke or to learn a talent so as to narrow the distance with the opposite sex, and then develop the special atmosphere of ¡§pick up a girl and fight side by side, ¡§and abandon the competence of masculine ranking between each other. ¡@¡@Finally, Giddens mentioned that in the discussion of heterosexual relationships and intimacies, the intimacy of modernity are becoming more and more plasticity and fluidity. However, to those busy on the work called ¡§High tech millionaires,¡¨ the ideal image for equal intimacy relationships was inappropriate. To high tech millionaires, the management of intimate relationships of the expectations and awareness in the public and private sector did not develop into so-called pure relationships by Giddens, corresponding to Jamieson¡¦s questioned that there are many changes or unchangeable factors which affect the management of intimate relationships in real life. Therefore, the researcher tries to analysis the attitude and imagination of the high tech millionaires to heterosexual relationships and management of intimate relationships, to understand how engineers from the masculine workplace and rational dominance transition to the fields of intimate relationships.
