본 연구는 최근 대학경영에 있어서 '고객'이라는 개념의 인식과 고객지향적 경영전략의 중요성이 확대됨에 따라 대학산업에 적합한 전사적 CRM 전략을 본격적으로 논의하기위한 토대로써 대학의 유형별 CRM 전략 요소의 차이점을 검증하고자 하였다. 이를 위해 CRM 전략의 핵심 프레임워크인 CRM 프로세스(CRM Process)와 고객자산가치 운영요소(Customer Equity Drivers) 이론을 중심으로 대학경영에 적합한 CRM 전략요소 측정도구를 개발하고, 대학의 평가순위과 대학의 소재 지역에 따라 구분되는 12가지 대학유형간의 차이를 다변량 분산분석 (MANOVA)을 통해 검정하였다. 분석결과, CRM 프로세스 활동과 고객자산가치 요소들의 수준이 대학의 평가순위 그룹유형에 대해서는 유의한 차이가 있지만, 대학의 소재 지역 그룹유형에 대해서는 통계적으로 유의한 차이가 존재하지 않았다. 즉, 관계획득활동과 관계강화활동이 상위권 대학과 하위권 대학에서 유의하게 차이가 나는 것을 알 수 있었고, 고객자산가치 요소 중 상위권 대학의 브랜드가치와 관계가치는 중위권 대학 및 하위권 대학과 유의한 차이가 발견되었으며, 또한 상위권 대학의 제품/서비스 가치(구매가치)는 하위권 대학의 구매가치와, 그리고 중위권 대학의 브랜드 가치는 하위권 대학의 브랜드 가치와도 분명한 차이가 존재한다는 것을 알 수 있다. One of the recent research trends that universities are increasingly adopting the concept of 'customer' and the customer-oriented strategy has urged us to research enterprise-wide CRM strategy adaptable to university administration. As the first step of CRM strategy for university management, we try to validate the difference of CRM strategic factors among university types. Drawing upon both CRM process and customer equity drivers, which have been recognized as core frameworks for CRM strategy, we developed those survey instruments adoptable into university industry, and validated statistically-significant difference among 12 types of university group constructed by the levels of university evaluation and the location of the universities. We collected 261 responses from 177 universities from all over the country and analyzed the data to see the levels of CRM processes consisting of customer acquisition, retention, and expansion, and customer equity drivers consisting of value equity, brand equity, and relationship equity by using multivariate ANOVA(MANOVA). The result confirms the explicit differences of the levels of CRM processes and customer equity drivers between the groups by university evaluation levels(high/middle/low). However, the analysis failed to show the significant differences of those between the group by university locations(the capital/the suburbs/the six megalopolises/other countries). More specifically, the level of activities for customer acquisition and retention of the universities in the higher-graded group are significantly different from those in the lower-graded group from the perspective of CRM process. In terms of customer equity drivers, the levels of both brand equity and relationship equity of the higher-graded group are significantly higher than those of both middle and lower-graded group. In addition, we found that the value equity between the higher and lower-graded groups, and the brand equity between the middle and lower-graded groups are different each other. This study provides an important meaning in that we tried to consider CRM strategy which has been mainly addressed in profit-making industries in terms of non-profit organization context. Our endeavors to develop and validate empirical measurements adoptable to university context could be an academic contribution. In terms of practical meaning, the processes and results of this study might be a guideline to many universities to build their own CRM strategies. According to the research results, those insights could be expressed in several messages. First, we propose to universities that they should plan their own differentiated CRM strategies according to their positions in terms of university evaluation. For example, although it is acceptable that a university in lower-level group might follow the CRM process strategy of the middle-level group universities, it is not a good idea to imitate the customer acquisition and retention activities of the higher-level group universities. Moreover, since this study reported that the level of universities' brand equity is just correlated with the level of university evaluation, it might be pointless for the middle or lower-leveled universities if they just copy their brand equity strategies from those of higher-leveled ones even though such activities are seemingly attractive. Meanwhile, the difference of CRM strategy by university position might provide universities with the direction where they should go for their CRM strategies. For instance, our study implies that the lower-positioned universities should improve all of the customer equity drivers with concerted efforts because their value, brand, and relationship equities are inferior compared with the higher and middle-positioned universities' ones. This also means that they should focus on customer acquisition and expansion initiatives rather than those for customer retention because all of the customer equity drivers could be influenced by

A beam composed of two different materials are called bi-material beams. In case of bi-material beam analysis, it is very difficult to consider detailed material properties. Thus, we need to obtain approximately equivalent beam properties. In this paper, we derive equivalent material properties of bi-material beam for the efficient finite element eigen analysis. Through the comparison with three dimensional finite element model, the proposed numerical technique for bi-material beams is verified.

Modified Ni/YSZ cermets for high temperature electrolysis were synthesized by the direct ball milling of Ni and YSZ powder. The ball milling was carried out in dry process and in ethanol with varying milling time. While the dry-milling decreased the average size from 65 to $80{\mu}m$, the wet-milling decreased the average size down to $10{\mu}m$. In addition, very fine particles less than $0.1{\mu}m$ were observed in the wet-milling condition. The subsequent process of cold-pressing and sintering at $900^{\circ}C$ for 2 h did not affect the particle size of dry-milled powder. The electrical conductivity of the dry-milled Ni/YSZ cermet showed the value of $5{\times}10^{2}\;S/cm$ and this value was increased to $1.4{\times}10^{4}\;S/cm$ after the sintering at $900^{\circ}C$ for 2 h.

In order to produce high-quality optical components, aspheric lenses have been widely applied in recent years. An aspheric lens consists of aspheric surfaces instead of spherical ones, which causes difficulty in the design process as well as the manufacturing procedure. Although injection molding is widely used to fabricate optical lenses owing to its high productivity, there remains lots of difficulty to determine appropriate mold design factors and injection molding parameters. In the injection molding fields, computer simulation has been effectively applied to analyze processes based on the shell analysis so far. Considering the geometry of optical lenses, a full-3d simulation based on solid elements has been reported as a reliable approach. The present work covers three-dimensional injection molding simulation and relevant deformation analysis of an injection molded plastic lens based on 3d solid elements. Numerical analyses have been applied to the injection molding processes of three aspheric lenses for an image sensing module of a mobile phone. The reliability of the proposed approach has been verified in comparison with the experimental results.

Most of CAE analyses for injection molding have been based on the Mele Shaw's approximation: two-dimensional flow analysis. in some cases, that approximation causes significant errors due to loss of the geometrical information as well as simplification of the flow characteristics in the thickness direction. Although injection molding analysis software using three-dimensional solid elements has been developed recently, such as Moldflow Flow3D, it does not contain a deformation analysis function yet. The present work covers three-dimensional deformation analysis or injection molded plastic parts using solid elements. A numerical scheme for deformation analysis has bun proposed from the results of injection molding analysis using Moldflow Flow3D. The accuracy of the proposed approach has been verified through a numerical analysis of rectangular plates with various thicknesses in comparison with the classical shell-based approach. In addition, the reliability of the approach has also been proved through an industrial example. an optical plastic lens, in comparison of real experiments.

복합단면을 갖는 비 감쇠 보 구조물의 유한요소 고유치 해석

보 구조물의 고유치 해석의 경우 보 이론에 근거한 기존의 다양한 방법들을 통해 효율적이고 수월하게 수행이 가능하다. 하지만 보의 단면이 두 가지 이상의 복합재질로 구성되어 있을 경우 전통적인 보 이론을 적용하기 위해서는 단일의 등가 물성을 산출해야할 필요가 있다. 본 논문에서는 복합단면 보 구조물의 효율적인 유한요소 고유치 해석을 위해 등가의 물성을 산출하였다. 이론 연구를 토대로 개발한 연구용 프로그램으로 대표적인 보 구조물에 대한 유한요소 고유치 해석을 수행하였으며, 해석결과에 대한 신뢰성 검증을 위해 상용 소프트웨어인 ANSYS의 3차원 솔리드 모델의 해석결과와 비교하였다. Numerical eigen analysis of beam-like structure can be easily and effectively done by various conventional beam theory-based methods. However, in case of the structures composed of composite-sectioned beams, the application of conventional numerical methods requires one to derive both equivalent material and geometry properties. In the present paper, these equivalent properties are derived by the transformed section method and the test FEM program is coded. The numerical accuracy of the proposed method is verified through the comparison with the ANSYS 3-D model.

Transient characteristics of a boiler and turbine system for a steam power plant are simulated. One-dimensional unsteady models are introduced for each component. An interaction between boiler and turbine and a control of the water level in the drum are taken into account. Transient responses of the system to the variations of main system variables such as fuel and air flow rate, cooling water injection rate at the attemperator, gas recirculation rate at the furnace and opening of the turbine control valve are examined. Effect of fluid inertia and tube wall thermal inertia on predicted dynamic behavior is investigated.
