  • Today's manufacturers must respond quickly to customer needs. In particular, make-to-order companies are constantly striving to satisfy customer demand for products in order to secure more favorable conditions in the future through bidding. In this bidding process, quotations play a very important role in providing favorable conditions. And the most important content that companies strive to satisfy their customers is the product's performance. Therefore, a company can attract customers and secure economic profits through good quotations, but it can be said that the first priority is to match the performance of the products requested by the customers. That is, when a company creates a quotation, it is important to structure the quotation according to the performance of the product. Thus, this paper intends to present a quotation management framework and a quotation BOM information model for constructing quotations efficiently in make-to-order manufacturing. And, in order to prove the usefulness of the proposed quotation management framework, we presents an case of the construction of an quotation management system based on the JAVA platform. As a result, the integrated quotation management system based on the proposed quotation management framework and quotation BOM has been successfully operated in a make-to-order company that manufactures marine engines.

  • We systematically analyzed the Wetland Conservation Action Plan of Gyeongsangnam Province to evaluate conservation status in local government level. Project topics were categorized into 1) wetland infrastructure, 2) wetland conservation and wise use, 3) education and awareness, and 4) conservation framework. From 2010 to 2013, 42 projects (145 cases, 88,899 million won) were implemented by 14 affiliated organizations under Gyeongsangnam Provincial Government. The number of projects and budget size has been decreased over 4 years, besides most of main projects were continued. The budgets were largely used for wetland project of cities and counties. Development and implementation of various conservation projects may have considerable potential values in wetland conservation, while it is still difficult to assess their overall effectiveness in the society. Diverse wetland management practices in Gyeongsangnam Provincial Government have accumulated fundamental practices and knowledge for an effective local conservation. These administrative experiences will further benefit other local government to establish wetland management framework. To accelerate policy diffusion to other local governments, Gyeongsangnam Province needs to promote and share leading experiences and information of wetland conservation. Enhanced local government framework by the legislation at central government will further support country-level management plans and practices.

  • The purposes of this study were to inform the exemplary models of integrated science and mathematics and to analyze and discuss their similarities and differences of the models. There were two steps to select the exemplary models of integrated science and mathematics. First, the second volume (Berlin & Lee, 2003) of the bibliography of integrated science and mathematics was analyzed to identify the models. As a second step, we selected the models that are dealt with in the School Science Mathematics journal and were cited more than three times. The findings showed that the following four exemplary theoretical models were identified and published in the SSM journal: the Berlin-White Integrated Science and Mathematics (BWISM) Model, the Mathematics/Science Continuum Model, the Continuum Model of Integration, and the Five Types of Science and Mathematics Integration. The Berlin-White Integrated Science and Mathematics (BWISM) Model focused an interpretive or framework theory for integrated science and mathematics teaching and learning. BWISM focused on a conceptual base and a common language for integrated science and mathematics teaching and learning. The Mathematics/Science Continuum Model provided five categories and ways to clarify the extent of overlap or coordination between science and mathematics during instructional practice. The Continuum Model of Integration included five categories and clarified the nature of the relationship between the mathematics and science being taught and the curricular goals for the disciplines. These five types of science and mathematics integrations described the method, type, and instructional implications of five different approaches to integration. The five categories focused on clarifying various forms of integrated science and mathematics education. Several differences and similarities among the models were identified on the basis of the analysis of the content and characteristics of the models. Theoretically, there is strong support for the integration of science and mathematics education as a way to enhance science and mathematics learning experiences. It is expected that these instructional models for integration of science and mathematics could be used to develop and evaluate integration programs and to disseminate integration approaches to curriculum and instruction.

  • Sensing coverage is a fundamental issue for Wireless Sensor Networks (WSNs). Several coverage configuration protocols have been developed; most of them presume the availability of precise knowledge about each node location via GPS receivers. However, equipping each sensor node with a GPS is very expensive in terms of both energy and cost. On the other hand, several GPS-less localization algorithms that aim at obtaining nodes locations with a low cost have been proposed. Although their deep correlation, sensing coverage and localization have long been treated separately. In this paper, we analyze, design and evaluate a novel integrated framework providing both localization and coverage guarantees for WSNs. We integrate the well-known Coverage Configuration Protocol CCP with an improved version of the localization algorithm AT-Dist. We enhanced the original specification of AT-Dist in order to guarantee the necessary localization accuracy required by CCP. In our proposed framework, a few number of nodes are assumed to know their exact positions and dynamically vary their transmission ranges. The remaining sensors positions are derived, as accurately as possible, using this little initial location information. All nodes positions (exact and derived) are then used as an input for the coverage module. Extensive simulation results show that, even with a very low anchor density, our proposal reaches the same performance and efficiency as the ideal CCP based on complete and precise knowledge of sensors coordinates.

  • The tax system in Korea is the so-called one-item-one-tax law which has separate tax law for each taxation according to tax law. The common and procedural aspects of these tax laws are the same or similar, but they are separately prescribed by the National Tax Basic Act and the Local Tax Act. These legal systems complicate the tax law and increase the cost of tax cooperation, resulting in tax inefficiency. In this study, the National Tax Act and the laws of the Local Tax Act are integrated and presented. It is proposed that the common provisions should be integrated into a single law and the unique matters should be defined in each of the National Tax Basic Act and Local Tax Basic Act, by comparing and analyzing the provisions of the National Tax Basic Act and the Local Tax Basic Act. The integration of the common elements of the National Tax Basic Act and the Local Tax Act is expected to improve tax efficiency by reducing tax complexity and tax cooperation costs. In addition, the National Tax Act and the Local Tax Act are expected to maintain the characteristics of the National Tax Basic Act and the Local Tax Act when they are specified in the National Tax Basic Act and the Local Tax Basic Act. This study is expected to be a research that can reduce tax inefficiency and help convenience of taxpayer and tax administration.

  • Purpose: Once the decision has been made to adopt an integrated medical information system (IMIS), there are a number of issues to overcome. Users need to be aware of the impact the change will make on end users and be prepared to address issues that arise before they become problems. The purpose of this study is to investigate the benefits and unexpected problems encountered in the implementation of IMIS and to determine a useful framework for IMIS. Materials and Methods: The Yonsei University Dental Hospital is steadily constructing an IMIS. The vendor's PACS software, Piview STAR, supports transactions between workstations that are approved to integrating the healthcare enterprise (IHE) with security function. It is necessary to develop an excellent framework that is good for the patient, healthcare provider and information system vendors, in an expert, efficient, and cost-effective manner. Results : The problems encountered with IMIS implementation were high initial investments, delay of EMR enforcement, underdevelopment of digital radiographic appliances and software and insufficient educational training for users. Conclusions: The clinical environments of dental IMIS is some different from the medical situation. The best way to overcome these differences is to establish a gold standard of dental IMIS integration, which estimates the cost payback. The IHE and its technical framework are good for the patient, the health care provider and all information systems vendors.

  • Dokdo research has been worked in various fields. However, the continuous accumulation and systematic management of Dokdo research data on marine science haven't been made. In particular, a systematic database system hasn't been established for the research data on marine environment and ecosystem in Dokdo and its surrounding sea. Therefore, GIS database construction on a spatial basis is required for the systematic management and efficient use of Dokdo marine research data, and a marine data model on a GIS basis is needed on the design stage to build the database. In this study, we collected previous observed marine data, and classified them as three groups, such as a framework data group on a GIS basis, a research data group and a thematic data group, according to the data types and characteristics. Moreover, the attributes of each research data were designed to be connected to GIS framework data. The result of the study to build an integrated GIS data model may be useful for developing a management system for marine research data observed in other sea as well as Dokdo.

  • The quality of records determines the value of records as assets in the digital age. It depends on how consistently record requirements can be applied during the records production and utilization processes using mostly IT systems. Therefore, the importance of effective records management (RM) governance applied for all organizational areas cannot be emphasized enough. The purpose of this paper is to propose a new framework of RM governance in order to produce and manage more valuable records, and the way to implement it in an organizational context. For the purpose, this paper discusses the necessity of a governance framework to formulate and operate consistent policies and procedures for overall processes of production, distribution, utilization and protection of records based on the values of evidence and information. Next, it proposes an integrated model by linking the management framework of the Information Governance Reference Model (IGRM) and the Management System for Records standards (ISO 30300 series; MSR) for the effective RM governance to be implemented in an organizational context.
