Due to the development of the online and mobile, cases of introducing CMS(Contents Management System) and WCMS(Web Contents Management System) to manage Web-Contents of individual and company's homepage are continuously increasing. In this paper, it is necessary to develop WCMS that can establish GUI(Graphic User Interface) based WCMS and edit contents using more concise procedures. In this paper, by reconfiguring WCMS-based Web contents using user-definition, we designed the system that can effectively and conveniently edit web contents as GUI-based. Also, we studied the intuitive and convenient web-contents management methods through researches using simplified logic. Therefore, proposed WCMS based Web-contents editing system allows the users to edit and modify the web contents much more quickly and conveniently compared to the existing web-contents editing system.

In this paper, we design and implement the web-based property management system using RFID. There are many properties in the organizations such as companies, schools and so on. Many users share these properties. Thus, these fields require efficient management systems for monitoring a variety of information such as the locations and the detailed information of the properties for the monitoring and lending services. We attach RFID tags to every property and monitor their information with our web-based management system. Our management system provides the monitoring service and the lending service for properties and users.

최근 인터넷과 같은 컴퓨터 네트워크 기술이 발전함에 따라 민간이나 정부 분야에서 전자적 거래(Electronic transaction)가 급증하고 있다. 컴퓨터 네트워크를 통한 원격지간의 비대면 거래방식은 시대가 바귐에 따라 피할 수 없는 현실이 되었으며, 경제\ulcorner경영전반에서도 디지털경제의 도입이 확산되었다. 이러한 흐름으로 전자상거래/e-비즈니스는 기존의 오프라인 매장에서의 구매판매활동을 온라인으로 확대하여 많은 경영 활동이 이루어지고 있다. 전자상거래는 말 그대로 전자적으로 물건을 구매하거나 판매하는 형태로 대금을 지불하는 등의 일반상거래와 관련된 모든 작업을 전자적으로 처리하는 것을 말한다 즉, 컴퓨터와 컴퓨터 통신망을 이용하여 상거래를 수행, 관리하는 새로운 비즈니스 방식을 뜻한다. 전자상거래 시스템은 수많은 종류의 시스템들이 있고, 운영 방식 역시 다양하다 이러한 전자상거래 시스템은 각자 여러 가지 장점과 단점을 지니고 있다. 전자상거래 시스템을 운영하고 있는 현 기업을 대상으로 현재 운영중인 시스템현황, 시스템 구축서버 현황, 시스템 구축언어, 데이터베이스 시스템, 보안 및 침입탐지 시스템, XML의 운영 현황 등의 전자상거래 시스템 활용 현황을 조사 분석하여 조사대상 대기업과 기업에 대해 업종별 분류를 활용하고, 업종별, 연도별 전자상거래/e-비즈니스 활용의 추이를 전망 예측할 수 있으리라 기대된다.

Firm's competitive advantage and profitability can be gained over competitors by human resources and human resource management that are characterized by idiosyncrasies or differentiation. Yet, the results of previous studies have been a emerging consensus that the isomorphism and homogeneity of HRM and HR practices among firms regardless of thoese industrial areas, size, organizational settings, etc. are universal. Based on the previous studies of similarities of HRM, the paper theoretically investigates the background and reasons of introducing similar HR practices among firms. The paper shows the dynamism of HR system in Korean firms, adapting a new HR system. Three types of reasons are found, coercive isomorphism, mimetic isomorphism, and normative isomorphism. However, it is also discussed that there is an important gap in the theoretical and empirical research. More empirical research is suggested in order for gaining meaningful results on HR studies.

The computer systems of many hotel businesses in Korea do not really succeed in keeping up with the rapidly developing IT technology. It is essential that they keep updating the information systems of hotels, which will eventually result in enhanced customer satisfaction. They also need to make every effort to develop and maintain appropriate computing systems to improve the quality of service to customers. This paper discusses how computers have been introduced to hotel businesses and how the intended goals have been materialized. We attempt to examine the information systems of some Korean hotels and see if there is any problem that needs to be solved. From the perspective of a general information system, we intend to make a proposal to optimize the computer system of the hotels.

The recent trend of the hacking deals with all the IT infrastructure related to the profit of the companies. Presently, they attack the service itself, the source of the profit, while they tried to access to the service infrastructure through the non-service port in the past. Although they affect the service directly, it is difficult to block them with the old security solution or the old system and they threaten more and more companies with the demand of money menacing the protection of customers and the sustainable management. This paper aims to design and implement multi-platform network packet scanner targeting the exception handling network intrusion detection system which determines normal, abnormal by traffic. Linux and unix have the various network intrusion detection and packet management tools like ngrep, snort, TCPdump, but most of them are based on CUI (Character based User Interface) giving users discomfort who are not used to it. The proposed system is implemented based on GUI(Graphical User Interface) to support the intuitive and easy-to-use interface to users, and using Qt(c++) language that supports multi-platform to run on any operating system.

The purpose of this study is to derive the suggestion of satisfaction of e-book services on the basis of the recent literature on quality assessment for e-service which have been mainly studied on library realm. For this purpose, This study added post-management service which is applicable to measure satisfaction of e-book services based on E-S-Qual and Libqual. We expand our scope of service to using of e-book content and services for individual customers, and analyzed the relationship between satisfaction with the system, the content, the after-sale service. On this foundation, existing e-book service companies can offer their services more efficiently, thereby making the e-book content more diverse, along with developing specialized e-book service to increasing their customer's satisfaction. In addition, the latest and diversity is important as well. Moreover, performing rapid post-management services after the sale of the product or service, can be important variables for customer satisfaction. Therefore, not only the system and content, providing required level post-management services by customers can satisfy the existing customers and create new customers.

The purpose of this research is to examine qualitative and quantitative performance on SCM. To validate our research model, five hundred survey questionnaires were distributed to the companies that have implemented SCM systems for at least one year. A total of 153 valid responses were obtained. In this research, we were to derive influencing factors of SCM performance, modelize the mutual influential relationship between them, and look into the influential relationship influencing the SCM performance. Moreover, we tried to analyze difference of financial ratios after adopting SCM. The results of the research can be summarized as follows. Change management had a significant impact on information system quality and SCM performance, and, information system quality had a significant impact on SCM performance. And, the difference of financial ratio was existed after the adopting SCM. Moreover, inventory turnover rates, ROI, ROA were increased, and labor costs to sales was decreased.
