The purpose of this study is to investigate the effects of home informatization on the family system. This study is based on the systems approach. A family system is composed of two major subsystems-personal and managerial. Managerial subsystem is concerned to instrumental function, such as time management and financial management. Personal subsystem is concerned to expressive function, such as family relations and interactions. So this study attempts to analyze the effects of Internet on the family system through time management, financial management, and family relations. The results from reviewing several related researches are that home informatization through Internet use has changed time management, financial management, and family relations. Finally this study suggests three plans of home informatization for contributing to improve the quality of family living.

Many enterprises have implemented packaged enterprise resource planning (ERP) solutions rather than system development on the promises of feasible strategic benefits. Typical feasible benefits include adoption of global standards and processes through a proven integrated system, continuous version upgrading by vendors, and thus the easiness of system maintenance. The objectives of this research are to identify what makes a post-implementation success of ERP system and to figure out the critical issues and factors for the successful upgrade of packaged ERP systems. This case study was conducted based on five different organizations that have experienced system upgrade implementation. Success factors of ERP system upgrade include (1) clear statement of upgrade goals, (2) good coordination and communication among the implementation partners, (3) thorough management of customization and maintenance history including documentation, (4) Planning of system requirements of higher version, and (5) redefinition of role between business departments and IT department.

Demand-side Management can be defined as'any utility activity aimed at modifying customers' use of energy to produce desired changes in the utility's load shape'. Customers benefit by being able to control energy costs and improve quality of life and become more productive. Utilities benefit from DSM's value as a resource that enhances asset utilization and reduces both fuel costs and environmental emissions. The scope of DSM includes load management through rate schedules and conservation by improving energy effciency and using electricity consumption effectively. This paper study the DSM resource evaluation and customer behavior analysis todesign the DSM Program plan in response to customer needs. We develop basic system dynamics model to analysis the customer behavior based on a survey research. The DSM Program participants in the Hi- efficiency Inverter, Electric motor and efficient lighting applicancies operating by Conservation program 2002 become the survey objects. DSM resource evaluation evaluate firstt the distribution potentialities of each machine and then forecast the degree of diffusion. We apply the system dynamic approach to simulate the dynamic DSM market situation at the domestic beginning. This model will give the energy Planner the opportunity to create different scenarios for DSM program planning. Also it will lead to increased understanding of the dynamic DSM market

This research develops a framework for resolving time and worker conflicts in the Critical Chain Project Management (CCPM) method, expressed in the form of a Max-Plus Linear (MPL) system. Our previous work proposed a method for resolving time conflicts. However, in practical cases, both time and worker conflicts may occur. Hence, we propose a method for resolving both time and worker conflicts for a single project. We first consider how to detect a resource conflict. Then, we define an adjacency matrix to resolve the detected conflicts. Using the proposed method, we confirm that the resource conflict can be resolved through a numerical example.

Target motion analysis with a sonar system in general uses a regular sampling time and thus obtains regular target information regardless of the target maneuver status. This often results in overconsumption of the limited sonar resources. We propose two methods of the IMM(interacting Multiple Model) PDAF algorithm for sonar resource management to improve target motion analysis performance and to save sonar resources in this paper. In the first method, two different process noise covariance which are used as mode sets are combined based on probability. In the second method, resource time which are processed from two mode sets is calculated based on probability and then considered as update time at next step. Performance of the proposed algorithms are compared with the other algorithms by a series of Monte Carlo simulation.

Many theorists argued that firms should obtain and their unique resources for sustained competitive advantage under the competitive business environment. Knowledge has been recognized as one of key strategic resource, which is scare, valuable and reasonably durable in both KM literature and practice. however, firms usually face difficulties in identifying which knowledge is a core strategic resource, so that they are wasting time and managerial energies by managing all of knowledge in an organization. This article is composed as follows, the definition of knowledge-management as the norm of the work process, the status arrangement of the knowledge-management system and the old information system of architecture and interior design, the knowledge-management system set-up method and model, and the knowledge creativity and the application culture make-up method. In particular, the present study explains the method that is applied to the use of the knowledge-management system and the application it.

국가경쟁력의 근간은 대학경쟁력이고 대학경쟁력은 학술 연구 정보경쟁력에서 나온다고 할 수 있다. IMD는 국가경쟁력에서 2위를 한 싱가포르가 대학경쟁력에서 1위를 한 것으로 보고하였으며, 국가경쟁력은 대학경쟁력에서 나온다고 평가한 바 있다. 그러나 우리나라에서는 국가 지식인프라 구축사업이 국가 단위의 종합적 계획없이 진행되고, 지식정보자원의 총량 분석없이 산발적 경쟁적으로 진행된 관계로 일반적인 정보원구축에 중복 투자가 되는 반면에 수집이 어렵고 많이 활용되지는 않으나 역사적 학술적 문화적 가치가 있는 정보원은 오히려 소외되는 현상이 발생했다. 이에 본 연구에서는 국가 자산인 국가지식정보자원 중 학술정보자원만이라도 총체적으로 관리하고 학술자원에 대한 총량분석을 기반으로 한 예산 투자 및 정보화사업과제가 발굴될 수 있도록 하기 위해 학술자원관리시스템 구축을 제안하고자 한다. 즉, 학술자원의 효율적 연계, 보급, 활용을 위해서는 관리체계가 필요하다고 보고, 이를 효과적으로 추진하기 위해 지식기반시대에 적합한 국가단위학술자원관리 체제 구축을 제안하고자 한다.

Purpose - In endless competition, companies pursue cost reduction and work efficiency. So, entrepreneurs try to increase job intensity, which may lead to job stress and high turnovers because of job burnout. But, Information systems are acknowledged as a work support tool that secures work convenience and the productivity of employees. In this study, we aimed to confirm the effects of information systems in reduing the work overload of employees in a human resource intensive industry. Research design, data and methodology - This is based on the job demands-resources model, conducting an empirical analysis of surveys given to hospital employees working in a human resource intensive industry. Results - The research revealed that information systems reduced the work overload of employees in a human resource intensive industry. Conclusion - This study confirmed the effects of information systems as a job resource based on JD-R theory, and presentation of empirical results indicated that information systems alleviate employee job overload and increases job satisfaction in the medical services industry. In the medical services industry, using electronic health record system decreases in work overload, which results in employees gaining time for self-development and time management, reducing job stress, and leading to job satisfaction.

최근 환경 오염 및 자원 고갈 등의 이유로 대체에너지원은 미래의 에너지원으로 중요한 역할을 하고 있다. 국외에서는 대체에너지원에 관련된 정보 시스템의 개발 및 보급이 활발히 추진되고 있다. 그러나 국내에서는 대체에너지원 데이터의 효율적인 이력 관리 및 웹을 통한 검색 서비스가 제공되지 않고 있다. 따라서 이 논문에서는 대체에너지원 데이터의 방대한 이력 정보를 체계적으로 저장 및 관리하기 위한 대체에너지원 이력 데이터 관리 시스템을 제안한다. 이 시스템은 외부 관측 시스템으로부터 대체에너지원 데이터를 수집하여 이력 데이터베이스에 저장한다. 저장된 정보는 이력 질의 처리를 통해 검색되고 테이블, 그래프, 챠트, 등고선 등의 다양한 형태로 인터넷을 통해 제공된다. 특히, 제안 시스템은 실시간으로 이력 데이터를 관리하므로 사용자는 웹 인터페이스를 통해 항상 최신의 정보를 제공받을 수 있는 특징을 갖는다.
