In this study, the high speed machining experiment was carried out on aluminum alloy(Al7075) using high speed precision turning system, and investigated that how changes of cutting condition such as nose radius, cutting speed and depth of cut have an effect on chip form, chip curl radius and surface roughness. The high speed machined surface had an uniformed appearance compared to conventional machined surface. Therefore, it was convinced of the possibility of high quality machining by high speed machining. Variation of chip curl radius increased when nose radius was smaller, however it decreased when cutting speed and depth of cut were smaller. The characteristics of surface roughness was appeared to similar tendency of theoretical surface roughness(R_(max)=f²/8R) according to the change of nose radius, however it was not affected by either cutting speed or depth of cut.

The purpose of this research is to explore The Minister of Tourism? or The Head of the Tourism Agency? In-depth interviews with 10 tourism experts were conducted by asking questions about the past, the present, and the future of South Korea Government Tourism Organization. The 10 interviewees were conveniently selected and they had more than 25 years of working experience. The in-depth interview was administered from February to July in 2019. Results showed that the answers of the interviewees about the past, the present, and the future were closely related to each other. In other words, the fact that Korea is not highly dependent on tourism industry whose contribution to the national economy is not so significant has made it challenging for the government to create an independent organization for tourism alone in the past. Despite the growing importance of the tourism industry which has become high value-added ever in the history, it may be rather too early to foster a tourism department in the government organization, considering its little influence on the economy. Also, it is about time to proactively consider the ‘pre-stage’ Ministry of Tourism since establishing an independent tourism department has a possibility of creating the departmental silos and the resistance from ministry of Culture and Sports.

Because stewardesses have to work based on irregular schedule and go abroad, they are assumed to have more conflicts between work and family than other working women. Stewardesses are part of the product and are therefore key front-line players in the tourism industry as they service guests during a journey. This study was to explore the characteristic of Korean stewardesses’s practical use using in-depth interview technique. 10 stewardesses who have more than four year work experiences were conveniently selected and in-depth interviewed from June 2014 to August 2014. The purpose of this study is to explore the characteristics of work among Korean stewardesses in Korea. Qualitative research approach was used to identify significant issues and draw out policy and managerial implications. So the Korean stewardesses’s career development and socialization process are explored. Based on the results, managerial and policy implications and future research directions are discussed.
