  • Organizations pursue a CRM strategy for the purpose of increasing business performance and value. However, firms face a multitude of organizational challenges associated with this endeavor. To reduce their risk of failure, it is suggested that firms undertake a deep analysis of organizational readiness prior to committing to a CRM initiative. Insurance sector is no exception to this fact. There is an increased need to concentrate on the various challenges thrown open by the public insurance firms in implementing CRM. Many insurance firms have invested into customer driven CRM but research indicates varying outcomes (Schmith 2004). While it is clear that there are significant issues involved in the CRM implementation and success and environment faced by the public sector. It is clear that business should have an easier time in applying CRM systems is the strategic value for public sector. With customers demanding more service and accessibility from administrators, public sector CRM software technologies have to offer best solutions for achieving process and cost objectives (Souder 2001). With results which go far beyond improved service delivery and include sustained cost reductions, increased customer knowledge and better employee morale, CRM software implementation and post product environments offer great upside value. Although there are material differences in public sector use of CRM strategy, they share at least one glaring similarity - they have much to gain from proven CRM software technology. As business methods cross over in the public sector, many government bodies are investigating how they can adopt and adapt various CRM models (Bleyer 2003). There is a need to understand the similarities and differences in public sector CRM to foster shared knowledge, business processes and planning functions to integrate disparate technologies and software platforms and then, of course, the organizational culture to support knowledge sharing (Peters 1997). For the public sector, there are clearly identified CRM processes which have resulted in increased profits and improved efficiency. These have focused on sales, marketing and customer service activities, which often operate along fundamentally different lines in various public sector insurance companies. Thus the present research paper makes an attempt to explore how public sector CRM methods can be adopted and subsequently adapted.

  • 자신이 경험한 교사 양성 프로그램에 대한 과학 교사의 인식을 조사하는 것은 과학 교사가 어떻게 교육되어야 하는가에 대한 개념화에 도움을 준다. 이러한 전제 하에 이 연구에서는 프로그램의 정합성과 균형성에 초점을 맞춰 예비 교사와 현직 교사의 과학 교사 양성 프로그램에 대한 인식을 조사하고자 하였다. 이를 위해 강원도 소재 사범대학의 과학 교사 프로그램을 이수한 20명의 예비 교사와 39명의 현직 교사가 참여 하였으며, 선택형 및 개방형 설문지를 개발하였다. 연구 결과는 다음과 같다; 첫째, 과학 교사 양성 프로그램의 정합성에 대해 예비 교사와 현직 교사는 '보통' 정도로 인식하는 것으로 나타났으며, '수업 계획 및 준비' 범주에서 가장 정합성이 높은 것으로, '직업적 책무' 범주에서 가장 정합성이 낮은 것으로 인식하였다. 또한, 4개 범주 모두에서 예비 교사에 비해 현직 교사가 프로그램의 정합성을 더 낮게 인식하는 것으로 나타났다. 둘째, 과학 교사 양성 프로그램의 균형성에 대해 예비 교사와 현직 교사는 모두 이론적 요소에 비해 실천적 요소가 부족한 것으로 인식하고 있었다. 셋째, 현행 과학 교사 양성 프로그램이 임용 고사를 위한 교육과정으로서의 성격이 강하다고 인식하고 있었으며, 프로그램의 4개 영역(교과내용학, 교과교육학, 일반교육학, 교생실습)이 학교 현장과 보다 더 연계되어야 한다고 인식하였다. 이 연구 결과를 토대로 보다 정합적이고 균형적인 과학 교사 양성 프로그램을 위한 대안적 방법을 논의하였다.

  • Nowadays various simulation tools are widely used for the design and the analysis of power electronic converters. From the engineering point of view it is rather difficult to parameterize power semiconductor device models without the knowledge of basic physical parameters. In recent years some data sheet driven behavioral models or so called 'wizard' tools have been introduced to solve this problem. In this contribution some experiences with some user-friendly power semiconductor models will be discussed. Using special simulation test circuits it is possible to get information on the static and dynamic behavior of the parameterized models before they are applied in more complex schemes. These results can be compared with data sheets or with measurements. The application of these models for power loss analysis of inverter type arc welding power sources will be described.

  • Attitudes of parents toward behavior guidance techniques used in pediatric dentistry have changed for decades. Some techniques were regarded acceptable with authority of dentists' assistance, but now face the objection of caregivers. For the way of breeding is changing, dentist should understand the situation and try to communicate with caregiver for eliminating misunderstanding of the procedures that could induce lawsuit for abusive techniques. Most of all, dentist should try to find the best method for the patient and help to overcome the fear and anxiety. The meaningful knowledge driven from clinical experience should be shared with other dentists to build up sound theoretical foundation.

  • The relationship between innovation policies and locational competitiveness has emerged as an important area in the analysis of economic development, reflecting both the centralisation and decentralisation of globalising economic activities. The underlying spatial and institutional components are subject to a pattern of cumulative causation in which strategic interventions of policy actors exercise a decisive role in shaping competitive advantages, while promoting interactions with local and foreign partners both from the private and public sectors. The Singaporean development experience illustrated these strategic interdependencies of innovation policies and locational competitiveness. Based on her role as a manufacturing and service hub, Singapore is viewed as an infrastructural nodal point which is interconnected to global production networks. Paralleling efforts in the domain of technological innovation, Singapore's policies for locational competitiveness aim at an adaptive harmonisation of the needs of international investors with local developmental objectives. This orientation characterises also current efforts in promoting Singapore as a knowledge agglomeration with a distinct science base, expanding R&D operations and an innovation-driven pattern of economic development. In conclusion, the locational rationale of Singapore's innovation policies provides lessons for dealing with the spatial and institutional implications of technological globalisation.

  • One of the most important prerequisites for a successful software process is the collaboration and software requirements negotiation of all stakeholders in the software development process. Remote users using computer networks can negotiate software requirements by computer supported system, and can share their informations. The goal of software requirements negotiation system is an integration of all win conditions and an agreement after resolution of conflicts. The existing systems need an exclusive system and must be dependent on specific platform and network. Users must have the knowledge of all stakeholder's status and use homogeneous collaborating applications. This paper presents the Web-based software requirements negotiation system for the purpose of resolution of the existing systems' problems. The Web-based software requirements negotiation system can be driven by WinWin Spiral model, and it is based on hybrid execution method. The proposed system is validated and tested on heterogeneous environments.

  • Sense and Respond Logistics(SARL) is a transformational, network-centric, knowledge-driven concept that enables joint effects-based operations and provides precise, agile support. Sense and respond logistics relies upon highly adaptive, self-synchronizing, and dynamic physical and functional processes. It predicts, anticipates, and coordinates actions that provide competitive advantage across the full range of military operations. In this research paper, we considered the essential prerequisite to introduce the appropriate SARL concept for the future warfare environment into the military logistics support system and also provide the conceptual alternatives to actualize the introduction of SARL.

  • Inchon Port is the second largest import-export port of Korea, and has the point at issue such as the excessive logistics cost because of the limits of handling capacity and the chronic demurrage. There are few research activities on the analysis and improvement of the whole port operation, because Inchon Port not only has the dual dock system and various facilities but also handles a various kind of cargo. The purpose of this paper is to develop the simulation program as a long-term strategic support tool, considering the dual dock system and the TU(Terminal Operation Company) system executed since March, 1997 in Inchon Port. The basic input parameters such as arrival intervals, cargo tons, service rates are analyzed and the probability density functions for these parameters are estimated. The main mechanism of simulation model is the discrete event-driven simulation and the next-event time advancing. The program is executed based on the knowledge base and database. From the simulation model, it is possible to estimate the demurrage status through analyzing various scenarios and to establish the long-term port strategic plan.

  • This paper proposes a simple adaptive sliding mode control algorithm for controlling a permanent magnet synchronous generator (PMSG) of a MW-class direct-driven wind turbine system. The proposed adaptive sliding mode controller does not require accurate knowledge of the PMSG parameter or turbine torque values. The proposed controller can accurately track the reference angular speed computed by the maximum power point tracking(MPPT) algorithm. Finally, this paper gives Matlab/Simulink simulation results to verify the practicality and effectiveness of the proposed adaptive sliding mode controller.
