파트너간 갈등과 협업이 컨밴션행사의 성과에 미치는 영향에 관한 연구
고상덕(Koh Sang Duk) 한국외식경영학회 2002 외식경영연구 Vol.5 No.2
A Study on the Impact of Collaboration and Conflicts among the Partners of Convention Events for the Performance Improvement. This study has explored whether the collaboration of partners of convention events affects the performance of the projects and it has also explored the relationship between the factors of conflicts among the partners and the project performances. This paper firstly among other things has briefly examined the types, scopes and purposes of collaboration and then the theories of cooperative options each partner takes to change the relationship for the maximization of profit. Once such a theoretical framework is set up, the study has established and tested hypotheses and models about the impacts of collaboration and knowledge transfer and conflict on the project performance. The article shows that general collaboration has a positive impact on the performance such as productivity and performance. the stronger the collaboration among the partners becomes, the more improvement is made for the performance. That is, the collaboration is shown to impact on the performance. Also, knowledge transfer from other partner affects the performance in the actual models verified in this study. Meantime, the impact of the conflicts in cooperative environment on the performance of the convention event shows rather negative results.

Angle씨 III급 부정교합 환자중 Activator사용 전후의 설골의 위치 변화에 관한 연구
고상덕(Sang-Duk Koh),차경석(Kyung-Suk Cha) 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.4
This study was conducted to assess the positional changes of hyoid bone following the use of activator in Angles class III malocclusion patients with functional factors. For this study, 40 Angle´s class I patients and 40 Angle´s class III patients, totally 80 subjects were used. They are all in Hellman´s dental age IIIB-IIIC ranges. In lateral cephalogram to compare Angle´s class I group and Angle´s class III group, and the positional changes of the hyoid bone before and after the use of activator in Angle´s class III malocclusion group. The results were obtained as follows; 1. Comparison of Angle´s class I group and Angle´s class III group. In comparison to Angle´s class I group, hyoid bone is more anteriorly and superiorly positioned in Angle´s class III group. The hyoid bone showed reverse inclination to the mandibular plane in Angle´s class III malocclusion group. 2. Comparison of the hyoid positional change before and after use of Activator in Angle´s class III malocclusion group. The hyoid bone is displaced posteriorly and inferiorly in vertical relationship. The hyoid bone also showed counter-clockwise rotation. 3. No statistical difference was found between after Activator use data of Angle´s class III malocclusion group and Angle´s class I group. It is concluded that the hyoid bone in Angle´s class III malocclusion group changed its position, similar to Angle´s class I malocclusion group.
