One of the factors that influence the dynamic characteristics of machining systems is the cutting tool. Cutting tools are very diverse, and receptance coupling substructure analysis (RCSA) is essential for analyzing the dynamic characteristics of each tool. For RCSA, a full receptance matrix of the equipment and tools is essential. In this study, rotational degree-of-freedom receptance was estimated and analyzed using translational receptance. Displacement/moment receptance was analyzed according to the distance of the response point using the first-and second-order finite difference methods. The rotation/moment receptance was estimated according to the distance of the response point. Rotation/moment receptance was analyzed using Schmitz’s method and compensation strategies. The limitations of these strategies were analyzed, and the rotation/moment receptance for the beam under free-free boundary conditions was predicted using the second compensation strategy.

Purpose: This study is to evaluate the location of descending palatine artery, the anatomy of pterygomaxillary junction, and the association between the obtained anatomic values and several variables. Methods: We studied 40 patients who were treated for dentofacial deformites from January 2010 to December 2012 in Ulsan University Hospital, Ulsan, Korea. Cone beam computed tomogram (CBCT) was done for all patients. The reference point was approximately 5 to 7 mm above anterior nasal spine on axial image. We evaluated the location of the greater palatine canal (line a: on the coronal view, the shortest line between the center of greater palatine canal and pterygoid fossa; distance a: the distance of line a). We also measured the thickness (line b: on the coronal view, the shortest line between maxillary posterior sinus wall and pterygoid fossa; distance b: distance of line b), width (line c: on the coronal view, the line perpendicular to the line b and the nearest line from the most concave point of lateral pterygoid plate to the medial pterygoid plate; distance c: distance of line c) and height (line d: on sagittal view, the vertically longest line of pterygoid junction; distance d: the distance of line d) in pterygomaxillary junctions. We evaluated the association between the obtained anatomic values and several variables (sex, age, height and weight). Results: The mean distance a was 4.78 mm, mean distance b was 5.53 mm, mean distance c was 8.01 mm and mean distance d was 13.22 mm. The differences between age and mean distance c and weight and mean distance d in pterygomaxillary junctions are statistically significant. Conclusion: There apparently is anatomic variation of pterygomaxillary junctions by various values, particularly weight and age in a Korean clinical population.

Health care marketers face unique challenges around the world, due in part to the role the health care field plays in contributing to public welfare. Hospital marketing in Korea is particularly challenging since Korean law prohibits hospitals from running any advertising. As a result, Korean hospitals depend heavily on customer relationship management (CRM). This study identifies five factors that influence the creation of brand equity through successful customer relationships: trust, customer satisfaction, relationship commitment, brand loyalty, and brand awareness. An empirical test of the relationships among these factors suggests that hospitals can be successful in creating image and positive brand equity if they can manage their customer relationships well.

본 연구의 목적은 IR 활동과 주주에 대한 관계마케팅간의 관련성을 연구하는 것이다. 본연구에 사용된 연구모형은 IR과 관계마케팅의 관련분야의 과거연구와 다양한 전문가들과의인터뷰를 통하여 축적된 자료들을 토대로 하여 구축되었다. 이러한 연구모형은 또한 과거연구와 전문가들과의 인터뷰를 통하여 얻어진 연구가셜들을 기반으로 하였다. LISREL 분석기법을 이용하여 자료분석이 시도되었다. 자료분석 결과에 의하면 IR활동들이 투자자의 신뢰와 관계결속에 결정적인 영향을 미치는 것으로 나타났다. 그리고 투자자의신뢰와 관계결속이 회사의 성과에 긍정적인 영향을 미치는 것으로 발견되었다. 따라서 IR활동들은 회사의 관계마케팅과 성과에 긍정적인 영향을 미친다는 결론을 도출하였다. 이러한결론을 바탕으로 IR활동과 관계마케팅의 관련성을 경영에 응용할 수 있는 다양한 마케팅전략이 제시되었다.

In Internet age, traditional transaction concepts are being examined in new perspectives. Electronic commerce, as a new transaction paradigm, is being paid attention to reexamine traditional marketing theories. In this study, equity is adapted to electronic commerce. We add Navigational Equity to existing equity concept: Payment and Service (Huppertz et a1 1978). The research model of this study consisted of three major constructs such as equity， normative comparison of equity and consumer satisfaction in electronic commerce. Additionally, the environments of Internet navigation, which include system quality, easy for use, social pressure, playful aspects, and security check, etc. were analyzed. The propositions were drawn from the research model of this study. These propositions will be used to generate hypotheses constructing simultaneous equation model. More empirical study of future is expected.
