In this paper, we describe the design details and their implementation of a workflow model (or business process model) analysis system to be used for enhancing resource allocation efficiency and operational performance of enterprise workflows. In other word, the analysis works, proposed in this paper, on XPDL-based workflow models aim to verify the static aspects of the workflow models. Also, the system implemented in the paper is able to not only analyze structural patterns and resource allocation plans' efficiency of enterprise workflows modeled by the XPDL process definition language developed by the international standardization organization, WfMC, but also provide various forms of analytical reports. Conclusively, we strongly believe that the workflow analysis system developed in the paper enables workflow modelers to not only analyze and scrutinize structural patterns of their workflow models but also estimate their process resources assigning and planning measurements in order to improve accuracy, reliability and efficiency of enterprise workflows.

의료기관의 응급실은 환자의 생명을 다루는 긴박한 현장으로 환자에 대한 실시간 모니터링 및 관리가 필수적으로 요구되는 곳이다. 본 연구에서는 기존 응급실 진료 프로세스를 체계적으로 관리하고 모니터링 하기 위해 BPM 아키텍처를 도입하여 응급실 업무들을 표준화, 가시화함으로써 의료진의 신속한 응급 업무 대응이 가능한 응급신속대응관리시스템(EQRMS-Emergency Quick Response Management System)를 제안한다. 의료기관에서 BPM의 도입은 단순히 병원 경영 목표나 병원 내외부의 운영을 모니터링 할 수 있는 이점 이외에 병원 업무의 이윤을 극대화 할 수 있는 다양한 효과가 있다. 또한 임상위험수치 (CV-Critical Value)를 정의함으로써 복잡한 검사의 단순화와 검사 시간 단축, 검사의 오류 발생률 감소 등 환자의 안정성 제고 측면에도 크게 기여할 것이다.

Exchange of data between users and system is made by users' inputting their information into HTML input forms like when signing up in websites or buying in online shopping malls. If users make a mistake of inputting their information, the system gives an error message in order for users to correct their mistakes. Although ISO recommends immediate feedback, Bargas et al. gave a report that feedback in all after filling forms out is more usable than feedback one by one when inputting data online. We made a comparative experiment on usability under each case of feedback one by one and feedback in all. The result is immediate feedback is more usable and satisfactory. The analysis of data resulted that immediate feedback produced fewer error and gets higher subjective ratings.

Body sizing of has been recognized as an important element affecting the degree of customer satisfaction in the apparel industry. Recent developments in IT technologies have enabled more studies in custom-made apparel systems that comply with the diverse demands from customers in many countries. Diverse methods to obtain personal physical size are being studied. This study estimates the accuracy by developing the system in which the data of length and girth can be calculated through changing a modeling by comparing the data with circular 3-dimensional physical configuration data. This information was computed from the process (such as the conversion to a standardize image) which utilizes the image capture of 2-dimensional three sides (front, side, and rear), contour tracing, and key-node selection and by realizing it in the real world.

Aspect-Oriented Programming (AOP) has focused on improving the modularity of the crosscutting concerns. The existing AOP methodology has been mainly focused on the implementation method of programs and thus developer-oriented concern extraction and development were performed. Recently, many studies for applying AOP to the entire software development processes ranging from requirement analysis to design and implementation are being conducted. But specification methods having consistency from the initial phase of concern extraction to implementation phase are not sufficient. In this paper, we have presented the specification of crosscutting concerns so as to solve these problems. The specification of crosscutting concerns provides guidelines and specification from the requirement analysis phase to the process of converting extracted crosscutting concerns to codes. This method reduces the gap to the process of mapping extracted crosscutting concerns into a single class and thus enhances program development and understandability. In addition, it raises program reusability, maintenance and extensibility by enhancing traceability.

With the expansion of internet usage and the advanced technology for information and communication, the international e-Trade environment gradually migrates from the VAN/EDI to the global Internet-based e-Traed on an ebXML framework. In an effort to provide a Internet-based e-Trade environment with a security and trust, this paper analyzes security components and proposed the SSL and ebXML security technologies in order to assure of the trust and security over Internet-based e-Trade. In addition, this paper presents 3-phase methodology to realize the secure and trustworthy Internet-based e-Trade. In summary, as the first phase, the e-Trade business processes are re-engineered and the digital signature council for mutual recognition is orgainzed. And as the second phase, the Internet-based e-Trade system and the concerned digital signature technology are implemented. Finally as third phase, the PKI mutual recognition agreement is signed by parties concerned and then the Internet-based e-trade business is started. Furthermore, this paper presents the promising Internet-based e-Trade models where the digital signature can be applied.

Recently, the software system is getting complicating and the customers are requiring faster development. For the traditional sequential approach can't against this problem iterative approach is used instead. For the representative iterative approach, there is RUP (Rational's Unified Process). However, RUP standard practical methods are phase, iteration, and disciplines, sequentially. As a result, there's some waste of manpower when a discipline is executed in an iteration, it has to wait till the next same discipline is executed. There are linear approach, sequential approach, overlapped iteration approach, and time-boxed iteration for the efficient execution of RUP. However, they have some problems such as waste of manpower or difficulty in the project management. This paper suggests a method about how to execute the disciplines as a concurrent type. The concurrent approach prevents the waste of manpower and solves the difficulty of project management.

It is important to operate an education resources which could be integrated to an system. But most of existing education information system was not developed with standardization. It is need the core education asset and reusable education service to make a good education system. Consequently, it is needed to use Sharable Content Object Reference Model(SCORM) based contents managing in order to reuse the contents of education. And it needs assembling and producing method with reusable core asset of education system to develop the application program for education. In this thesis, we study the Teaching-Learning supporting system to support systematic education resources. Teaching-Learning support system is developed of educational domain assess through development process based on Model Driven Architecture(MDA) and core asset on each stage. Application program of education is developed using MDA automatic tool through analyzing and designing for contents storage which is based on contents meta model. We finally can develop the application software of education with low cost and high productivity by raising the reusability of education contents and by using the core asset to the whole development process.

Recently, the buildings have been likely to shape Super Tall trend. Therefore, the exterior parts of the buildings come to be changed. Instead of early heavy wall structure, it is changed to light wall concept of curtain wall system. However, the curtain wall system causes lots of loads due to the external surrounding factors of building. In particular, due to the densely built-up condition in Korea, the generation of dew condensation is getting severer Since there has been no standardized process that reviews this generation of dew condensation, it is very urgent for us to prepare the reviewing process for the dew condensation for construction business managers. The purpose of this study is to assess dew condensation function of the curtain wall and provide the basic data for the provision of the future dew condensation review process by comparing and analyzing the range of generation of dew condensation as well as temperature distribution according to the change of relative humidity at the identical temperature by selecting the Unitized system and Stick system which are the representative types of curtain wall system.
