기업이 고객을 차별화하기 시작한 것은 고객관계관리가 확산되면서부터이다. CRM이 확산된 배경에는 마케팅활동이 브랜드중심에서 고객중심으로 옮겨가면서 고객관계와 고객자산의 중요성이 크게 부각되었고, IT를 기반으로 하여 고객정보를 획득하고 관리하며, 모형화 할 수 있는 능력이 경쟁우위를 지속하는데 핵심요소가 되었기 때문이다. 그러나 최근 CRM의 효과에 대한 회의론이 퍼지면서 학계와 실무진에서는 어떤 경우에 CRM의 성과가 나타나고, 어떤 경우에 실패하는가에 대한 연구가 활발히 이루어지고 있다. 저자들 또한 CRM 성과에 지대한 영향을 미칠 것이라고 생각되는 유통정보기술의 역할에 따라 기업의 CRM 성과가 어떻게 달라지는가를 검증하고자 하였다. 따라서 본 연구에서는 CRM 성과에 영향을 미치는 선행변수인 유통정보기술 요인으로 IT기술투자, IT 시스템 활용, Website 활용, 그리고 커뮤니케이션 등을 설정하였다. 본 연구는 CRM 성과는 IT 기술투자, IT 시스템 활용과 커뮤니케이션에 영향을 받을 수 있음을 가설로 제시하고, 설문조사 결과를 토대로 실증 분석하였다. 분석결과, IT 기술투자, IT 시스템 활용, 웹사이트 활용이 좋을수록 고객과 조직구성원간의 커뮤니케이션이 향상되는 것으로 분석되었다. 또한 IT 기술투자, IT시스템 활용, 고객과 조직구성원간의 커뮤니케이션이 좋을수록 기업의 CRM 성과는 향상되는 것으로 분석되었다. 마지막으로 본 연구가 갖는 학문적 의미와 관리적 의미를 제시하였다.

Recently, balanced scorecard is widely used in the public sector as well as in the private sector. Balanced scorecard system of a particular hospital is a very useful tool in the sense that it shows various measures for the management including the traditional financial measures. However, since it does not show the impact of action items, managers have to analyze his potential decisions. On the other hand, a system dynamics model for the management of a hospital can be used to predict future management status. In this paper, a balanced scorecard system with a system dynamics model is developed for a small sized hospital, and the feasibility and applicability of the system have been tested. It turns out the combination of the balanced scorecard and system dynamics technique can be comprised each other. The balanced scorecard system can take advantage of the data forecasted by the system dynamics model including the implementation of action items taken today. On the other hand, the key performance indicators and action items from the balanced scorecard system provide guidelines the scope and direction of the system dynamics model. The additional efforts of developing a system dynamics model are well compensated by the additional colorful functionalities of the system. This paper also covers the future research areas for the combined system to be more effectively developed.

정보기술(Information Technology)의 변화는 IT 인력에게 계속적인 역량개발을 요구하고 있다. 그로 인해 IT 인력의 역량개발이 기술의 변화를 따라가지 못한다면 IT 조직은 도태될 수밖에 없으며 업무를 수행함에 있어서도 여타 다른 인력에 비해 큰 지장을 받게 된다. 많은 기업들이 이런 이유로 IT조직을 별도로 관리하고 있으며, IT 직무체계를 기술기반에서 정립하여 관리하려고 시도하고 있다. IT 인력의 교육이 여타 다른 인력의 교육체계와 다른 특성을 보이고 있음에도 불구하고, IT 인력의 교육체계수립에 대해 이런 특성을 반영한 연구는 거의 이루어지지 않고 있다. 따라서 본 연구는 IT 인력의 교육체계를 수립하고 그 운영방안을 제도화하기 위한 프레임워크를 제시하고 그 프레임워크에 따르는 개별 프로세스를 제시하고, 그것을 사례 연구를 통하여 비교해 보고자 한다. 제시된 프레임워크와 프로세스의 특정은 IT 인력 교육의 특성을 고려하여 구성하였다. 본 연구는 최근 IT 인력 교육체계를 수립한 A사를 사례 기업으로 선정하여, 문헌연구를 통하여 도출된 프레임워크와 프로세스와 비교하였다. 이를 통하여 IT 인력의 교육을 위해서는 IT 직무체계의 합리적 수립이 필수적이며, 이를 위해 직무기술서가 IT 직무에 적합하게 구성될 필요가 있으며, IT 인력의 경력경로를 전문인력경로와 관리인력경로로 나누고 서로 다른 교육과정을 구성한다는 사실을 도출하였다. IT 교육훈련체계를 효과적으로 계속해서 운영하기 위해서 IT 인력 교육 담당자는 교육훈련대상자를 구별할 수 있어야 하고, IT 직무별 역량과 스킬을 잘 파악하고 있어야 하며, 기술적 지식을 가지고 항상 신기술 변화와 도입을 주시하고 있어야 한다.

In master-slave teleoperating system, it is important that the system has good maneuverability. In this paper, it is addressed an adaptive learning control method applicable to the master-slave system. This control scheme has the ability to estimate uncertain dynamic parameters included intrinsically in the system and to achieve the desired performance without the nasty matrix operation. The proposed method is applied to a master-slave teleoperating system composed of two SCARA robots and verified experimentally.

The virtual reality technology has been developed as the computer and computer graphic technology are progressed. However it has still the limits of the use because of it costs a great for system construction. A virtual reality technology is the best application example to reduce time and cost of development in engineering. Actually, VR(Virtual reality) technology has given engineers the ability to design, test and evaluate engineering systems in a virtual environment. The objective of this paper is to construct the arm mounted display VR system by using 3 channel spherical screen and to show its capabilities of an engineering system development. This paper describes the development of arm mounted display VR system with 3 channel spherical screen system and the generation of 3 channel graphic modules. The arm mounted display VR system provides a highly economical efficiency because of it uses a popular computer system as a graphic server.

The trailer system offers efficiency of transportation capability. However, it is difficult to control the backward motion. It is an open loop unstable problem. To solve this problem, we are proposed the driver assistance system. Driver assistance system assists a driver to control the backward motion of trailer system as if forward motion. A driver only secure the rear view of last passive trailer, and select the control input to drive the last passive trailer. The driver assistance system converts the control input of the driver into velocity and steering angle of the vehicle using the inverse kinematics. It is possible by electronic control input devices and the rear view camera. Effectiveness of driving assistance system is verified by the simulation and the experiments.

In discrete-time controlled system, sampling time is one of the critical parameters for control performance. It is useful to employ different sampling rates into the system considering the feasibility of measuring system or actuating system. The systems with the different sampling rates in their input and output channels are named multirate system. Even though the original continuous-time system is time-invariant, it is realized as time-varying state equation depending on multirate sampling mechanism. By means of the augmentation of the inputs and the outputs over one Period, the time-varying system equation can be constructed into the time-invariant equation. In this paper, an alternative time-invariant model is proposed, the design method and the stability of the LQG (Linear Quadratic Gaussian) control scheme for the realization are presented. The realization is flexible to construct to the sampling rate variations, the closed-loop system is shown to be asymptotically stable even in the inter-sampling intervals and it has smaller computation in on-line control loop than the previous time-invariant realizations.

In this paper, we deployed the tunnel inspection and monitoring system by wireless sensor network. It is shown that the wireless sensor network which is composed of sensor, wireless communication module, and gateway system can be applied to tunnel monitoring system. Sensors included herein are acceleration transducers, fire-alarm sensors, water-level sensors, and magnetic contact sensors. It is also found that the wireless sensor network can deliver sensing data reliably by ad-hoc networking technology. The gateway system that can send the sensing data to server by CDMA (code division multiple access) is developed. Finally, monitoring system is constructed by web service technology, and it is observed that this system can monitor the present state of tunnel without difficulties. Furthermore, the above system provides an alternative to inspect and monitor the tunnel efficiently where the conventional wired system cannot be applied.

From th Study on A Study on the Thesaurus of Korean medical information for developing search engine, the conclusion is as follow. Knowledge based information system consists of concepts, facts and relation. The final goal of developing the Knowledge based information system is to select, store and control the knowledge and information of Oriental Medicine. Considering limitation of organizing the knowledge system, it is difficult to realize complete basic system and application method. In order to work, it is necessary to combine experts in each part, for example Domain experts, Information and Knowledge engineer. Through the development of knowledge based information system, we can construct EMR(Electronic Medical Record) system in the near future, and it is possible to make semi-expert system. To make Knowledge based information system, we need to establish standards of information that make the distribution of Knowledge and information easily.
