B2B기업의 CSR명성이 영업사원의 소진(burnout)에 미치는 영향
정창모 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.10
Recently, the importance of B2B CSR is being highlighted. Meanwhile, in B2B marketing, salesperson is widely recognized as a key resource influencing supplier firm performance. Therefore, the author paid attention to the role of supplier CSR reputation in customer-salesperson interaction process. So, this study collected dyadic data from 161 B2B purchasing managers and salespersons interacting with them. For customers, a supplier CSR reputation increased customer citizenship behavior and customer long-term orientation. With salespersons, they experienced less burnout due to interacting with customers having higher customer citizenship behavior and long-term orientation. Moreover, the results confirmed that a supplier CSR reputation lowered salespersons’ emotional exhaustion through two serial-multiple mediation paths. This research verified that customers' perception and responses to supplier’s CSR significantly influence B2B salesperson burnout.
레이저용접,주조연결,그리고주조연결 - 레이저용접한 임프란트 보철물의 적합도 비교

An accurate and passive fit is necessary to maintain the functional integrity of implant prostheses. Poorly fitting implant restorations can result in biologic and mechanical failures. To improve the fit in prosthesis, various methods, such as laser welding and cast joining other than conventional soldering, have been developed. The purpose of this study was to measure and compare the strains produced by screw-tightening implant frameworks fabricated by three different joining methods; (1) laser welding, (2) cast joining, and (3) cast joining followed by laser welding of two half specimens and the secondary castings. In the third group, laser welding was employed to reinforce the weak cast joining. A research model incorporating eighteen strain gages was made to measure the fit of implant frameworks in three dimensions. Three implants with standard abutments aligned in an arc were fixed on the top ends of the L-shape aluminum bars of the research model. Three types of implant framework were placed on the abutments and screwed by a torque wrench using 10 Ncm. Under the conditions of this study, the following conclusions were drawn: 1. The three connecting methods yielded different results in regard to the accuracy of fit. 2. Cast joining group showed the smallest magnitude of total strain, followed by the laser welding group, and cast joining-laser welding. However, there was no significant difference between cast joining group and laser welding group. 3. The less magnitude of distortions were found in back-and-forth direction for cast joining group, in up-and-down direction for laser welding group, and in side-and-side direction for cast joining group and laser welding group than for the rest group or groups.
서스팬션 슈우퍼엘리먼트 기법을 이용한 자동차의 동력학적 해석

본 연구에서는 자동차의 동력학적 해석을 위한 특별프로그램을 만들어서 범용 프로그램인 DADS와 효율성을 비교해 보고자 한다. Dynamic analysis of a vehicle is carried out with rigid body and flexible body models. The chassis of the vehicle is treated as flexible body in the flexible body model, and vibration normal modes are considered to account for elastic deformation of the component. Using output from the modal analysis in the finite element program, input data for the dynamic analysis with flexible body is generated. To achieve the computational efficiency, SUPERELEMENT technique is used for the vehicle suspension subsisted. The computer simulation time with suspension superelement was much reduced due to the reduction of coordinates and no kinematic constraint in the system.
