호텔 Sales Force Control System이 직무성과에 미치는 영향
우희명(Woo, Hee Myung),정지원(Jung, Ji Won) 한국여행학회 2011 여행학연구 Vol.32 No.-
The purpose of this study is to suggest implications that reinforce job performance of hotel sales persons, through sales force control system. The analysis is as follow: ⅰ) Education & training, supervisor’s support, service orientation and cooperation with coworker have a positive effect on job-performance. ⅱ) The higher the job-satisfaction, the more the positive effect of education & training and supervisor’s support on job-performance. ⅲ) The higher the organizational commitment, the more the positive effect of education & training on job-performance. Through the forgoing analysis, implications to reinforce job-performance are presented.

폐비닐을 이용(利用)한 재생원료화(再生原料化) 기술(技術)
정수현,나정걸,김상국,우희명,김영태,Chung, Soo-Hyun,Na, Jeong-Gul,Kim, Sang-Guk,Woo, Hee-Myung,Kim, Young-Tae 한국자원리싸이클링학회 2013 資源 리싸이클링 Vol.22 No.4
국내에서 발생하는 폐플라스틱의 양은 폐비닐류를 포함하여 연간 500만톤에 이르며 이 가운데 재활용 선별장을 통하여 배출되는 폐비닐류의 양은 연간 100만톤 정도에 이르는 것으로 추정되고 있다. 재활용 선별장의 폐비닐류는 RPF(Refuse Plastic Fuel) 또는 재생원료로 전환되어 재활용이 이루어지고 있다. 본 연구에서는 재활용 선별장에서 발생하는 폐비닐을 열매체 가열공정에 의하여 용융처리하여 재생 폐비닐 원료로서 이용가능성을 인장강도를 통하여 분석하고 기존의 재생품과 비교함으로서 용융재생원료의 이용 가능성을 판단하였다. 상업용으로 사용하기 위해서는 폐비닐류를 이용한 재생원료의 인장강도는 100 $kgf/cm^2$ 정도가 적합함을 알 수 있었다. The produced quantity of waste plastics including waste vinyls was assumed as about 5 million tons per year. The quantity of waste vinyls produced from the waste recycling center among total quantity of waste plastics was estimated as about 1 million tons per year. Most of waste vinyls produced from the waste recycling center were recycled as refuse plastic fuel(RPF) or recycled feedstock material. In this study, the medium material using waste vinyls was made by the melting process of heat medium heating and the tensile strength was analyzed for checking the usable possibility of recycled waste vinyl material by comparing with the existent product. In order to use the medium material for producing the recycled product, it can be considered that the tensile strength of medium material is more than 100 $kgf/cm^2$.

Development of Source Dechlorination Process for Waste Vinyls
정수현(Chung, Soohyun),나정걸(Na, Jeonggeol),이종혁(Lee, Jonghyuk),우희명(Woo, Hee Myung) 한국신재생에너지학회 2011 한국신재생에너지학회 학술대회논문집 Vol.2011 No.05
Most of waste plastics including waste vinyls have been recycled up to about 50% of waste production, 4.5 million ton per year in 2009. To fundamentally increase the recycled amounts of waste plastics to waste production, the energy utilization of waste plastics is inevitable. But the contents of PVC included in waste plastics can limit the use as a RPF and make the air pollutants such as HCl and dioxin when it burns in the combustion system. Accordingly the source dechlorination by using heating method can be applied to make low contents of HCl as less than 0.6%. In this study the twin screw reactor using heat medium was used for the source dechlorination. As results of study, it was considered that this system is effective for the industrilal application.
