As the development environment is changing with the development of information communication technology, the systems that were used by each service became used with integration. In the process of integrating from existing legacy systems to new system, it should be smoothly integrated or shared, however, it cannot help holding existing technology or component due to significant cost burden for conversion. In this paper, it was not only classified by types with analyzing the various elements that make up legacy system but an approach and monitoring system were developed to each type. After System application results, data's information generated in each process is provided to other system in real time, so that it has not only secured the work efficiency and reliability but also it is made possible by integrating data in various formats for efficient data management, rapid search and tracking to history. With real-time monitoring system developed in this study, It can be very useful in a variety of industries which require real-time monitoring of distributed legacy system data.

The argument about enlarging or limiting the function of the Korea Maritime Police. Agency (KMPA) has been and will be repeated. In this paper, the author highlights the internal and external issues facing KMPA, stemming partly from deficiencies of its struggles for advancement of the organization and partly from shortcomings of political support far it. And he urges KMPA to change the organizational culture for maintaining its identity and characteristics as a lead maritime agency by practising a scientific management system for maximizing cost-effectiveness of its administrative resources. In addition, he also suggests that KMPA adopt the Total Quality Management System for quality improvements in services and greater efficiency in its organizational structure to meet the future competition in the changing political and legal environment. he concludes by providing a 6-point vision statement for KMPA from the standpoint of favoring enlarging the function of KMPA.

KICT has been carrying out inventory research on the cut slopes of national roads. Inventory research results are basic data used in cut slope management system. Inventory data are classified by general status, cut slope characteristics and inspector opinion. Cut slope inventory data are utilized to figure out dangerous slopes and decide survey ranking of detailed safety diagnostication. This paper drew the distribution of dangerous cut slopes using inventory data in Chungcheongdo, then verified an efficiency on distribution of dangerous cut slopes by comparing occurrence frequency of real collapsed cut slopes.

Cloud computing has brought changes to the IT environment. Due to the spread of LTE, users of cloud services are growing more. This which provides IT resources to meet the needs of users of cloud services are noted as a core industry. But it is not activated because of the security of personal data and the safety of the service. In order to solve this, intrusion detection system is constructed as follows. This protects individual data safely which exists in the cloud and also protects information exhaustively from malicious attack. The cause of most attack risk which exists to cloud computing can find in distributed environment. In this study, we analyzed about necessary property of network-based intrusion detection system that process and analyze large amount of data which occur in cloud computing environment. Also, we studied functions which detect and correspond attack occurred in interior of virtualization.

Pervasive computing and social network are good resources in recommendation method. Collaborative filtering is one of the most popular recommendation methods, but it has some limitations such as rating sparsity. Moreover, it does not consider social network in pervasive computing environment. We propose an effective proactive friend recommendation method using social network and contexts in pervasive computing environment. In collaborative filtering method, users need to rate sufficient number of items. However, many users don't rate items sufficiently, because the rating information must be manually input into system. We solve the rating sparsity problem in the collaboration filtering method by using contexts. Our method considers both a static and a dynamic friendship using contexts and social network. It makes more effective recommendation. This paper describes a new friend recommendation method and then presents a music friend scenario. Our work will help e-commerce recommendation system using collaborative filtering and friend recommendation applications in social network services.

Collaborative system is an essential idea in the global and e-business environments Workflow plays a key role implementing collaborative system. Workflow is an emerging technology for business process automation, monitoring integrity enforcement, and recovery. A process model describes the structure of business process in the real world The process model can be transformed into a Workflow model utilizing a computer. The paper proposes a web-based Workflow process design in the B2B environment Considering a global environment where the partners interchange their processes beyond the company boundaries, a web-based infrastructure is the most preferred platform Considering this, Workflow processes and e-Business structures were combined together on the web environment.

The purpose of this study was to investigate SCM performance of textile fashion business in a competitive market environment. For the methodology of this study, the questionnaire was developed based upon the literature. 230 questionnaires were distributed to the experts who operate SCM in textile fashion firms. The returned usable 149 were analyzed by SPSS10.0 with multiple regression analysis and Cronbach's Alpha for internal consistency and reliability. The results of this study were as follows: The SCM performance of the textile fashion firms was affected by information system, business environment, and partnership in a descending order. Analyzing on the business environment, CEOs' concern about incorporating SCM and the degree of assistance from government and textile fashion federation impacted the performance of SCM in a descending order. For information system, standardized computerization, information sharing, and computerization with infrastructure on intra/inter business impacted the SCM performance of the firms in a descending order. For partnership, strategic alliance, openness about corporate culture, and credibility of partnership impacted the SCM performance of the firms in a descending order.

Recently, flash memories are one of best media to support portable computer's storages in mobile computing environment. We propose a new transaction recovery scheme for a flash memory database environment which is based on a flash media file system. We improved traditional shadow paging schemes by reusing old data pages which are supposed to be invalidated in the course of writing a new data page in the flash file system environment. In order to reuse these data pages, we exploit deferred cleaning list structure in our flash memory shadow paging (FMSP) scheme. FMSP scheme removes the additional storage overhead for keeping shadow pages and minimizes the I/O performance degradation caused by data page distribution phenomena of traditional shadow paging schemes. We also propose a simulation model to show the performance of FMSP. Based on the results of the performance evaluation, we conclude that FMSP outperforms the traditional scheme.

As the environmental industry grew bigger and bigger, the corcern about environmental condition increased and the demand of environmental expert tended to be much more increased. A lot of universities therefore established environment-related departments on campuses and ended up with producing numerous students every single year. However, some problems such as followings were in this study. First, the industry cannot adopt all the students directly from universities due to their low capabilities in environment affairs. Second, the universities yield much more students than the industry can actually adopt. In order to yield the appropriate students meeting the expectation of the industry, it is necessary to permit no more new department established on campus and to adopt new environmental field such as environmental management, eco-auditing and also 3+1 lecture system focused on real affairs.
