The problem of the previous proprietary e-business systems is that they are not built upon well defined standards, which causes difficulties in extension of the system and interoperation among them. Therefore, a new e-business standard, ebXML, and related XML standards such as SOAP and XML Signature have been recommended for e-business systems. In this paper, as an application of the new XML standards, we design and implement a new internet bidding system. We use XML Schema for defining the document structure of the bidding system. DOM is used for structure search and XSL is used to represent styles. We use SOAP to handle distributed objects and XML Signature to provide data integrity. Due to the adoption of e-business standards, the developed system has advantages in interoperability and extensibility compared to previous systems.

We want to find a timestamping method which improves efficient performance and have high-level security to send secured messages in the digital signature and the law of e-commerces. Our paper shows a H-binary tree of time stamp to use a time stamp protocol with high security and performance in the packets of sending messages. We implement and analyze the protocols, show to compare with previous RSA methods. Our proposed protocol has O(log n) time complexity and high-performance.

“B2B 에서의 XML 보안”에 관해서 현재 많은 연구가 활발히 진행되고 있다. 인터넷상에서 뛰어난 확장성을 가지고 있고, 풍부한 자료구조, 국제적 문자에 대한 탁월한 처리를 가진 XML을 많은 기업들이 B2B(Business to Business)에서 많이 사용하고 있다. 또한 EDI(Electronic data Interchange)에서도 XML을 사용한 문서 교환이 활발하게 이용되고 있다. 하지만 XML에서는 보안에 관한 많은 취약점을 가지고 있는 것이 사실이다. 본 논문은 XML의 보안상의 취약점, XML의 보안에 대한 기술, 그리고 인터넷에서 XML 디지털 인증에 관해 구현하였다.

In apparel industry, the worksheet or product specification document has the function of products design. Drawing up worksheet exactly is important to quality control of apparel products. Every company needs to manage the product data of design-centric to establish TQM environment. In order to control the quality data of design-centric, an apparel worksheet system was developed by using the function of product data management system.

This paper presents the core technology of Construction Business Process Automation to model and automate construction business processes. Business Process Reengineering (BPR) and Automation (BPA) have been recognized as one of the important aspects in construction business management. However, BPR requires a lot of efforts to identify, document, implement, execute, maintain, and keep track thousands of business processes to deliver a project. Moreover, existing BPA technologies used in existing Enterprise Resource Planning (ERP) systems do not lend themselves to effective scalability for construction business process management. Application of Workflow and Object Technologies would be quite effective in implementing a scalable enterprise application for construction community. This paper present the technologies and methodologies for automating construction business processes by addressing how: 1) Automated construction management tasks are developed as software components, 2) The process modeling is facilitated by dragging-and dropping task components in a network, 3) Raising business requests and instantiating corresponding process instances are delivered, and 4) Business process instances are executed by using workflow technology based on real-time simulation engine. This paper presents how the construction business process automation is achieved by using equipment reservation and cancellation processes simplified intentionally.

Railroad logistics transporting freight by train takes charge of 10 or 20 percent of domestic cargos. Railroad logistics users such as transport companies including shippers or Inland Container Depot(ICD) use electronic document(EDI or XML) or input data through WEB to process railroad logistics business. However, as business environments evolving into e-business, it is required to upgrade the legacy railroad logistics process. As the increase of using ebXML-based schema format, it is also needed to improve the electronic documents based on DTD format into those of XML schema format. This study deals with information standard for railroad logistics to improve the railroad logistics business. To this purpose railroad business processes were re-defined through the standard business process modeling methodology. Information model was also derived by defining railroad logistics activities from business process model. And Business Information Entities(BIEs) were defined to design new electronic documents according to the extracted information model. An improved system architecture for railroad logistics was proposed as well. The results of this study will provide an effective and flexible business flow to railroad logistics business.

EDI (Electronic Data Interchange) has been widely utilized to support Business Activities since it has such advantages as fast transfer of information, less documentation work, efficient information exchange etc. Recently e-business environment has urged the traditional EDI system to be changed to ebXML framework. To apply the ebXML framework to a certain industry, it is required to implement Business Process (BP), Core Component (CC), Collaboration Protocol Profile (CPP), Collaboration Protocol Agreement (CPA), Messaging system etc. We have selected the port and logistics industry as a target domain to apply ebXML framework, since the EDI usage ratio of it is relatively higher than other industries. In this paper, we have analyzed the current status of EDI system and transaction processes in the port and logistics industry. We have defined the business process that will be registered in the registry/repository, the main component of ebXML framework, using UN/CEFACT modeling methodology. And Business Collaborations, Business Transactions, Business Document Flows, Choreography, Pattern, etc. are represented using UML according to UN/ CEFACT modeling methodology, to apply ebXML Framework to the port and logistics distribution industry. Also we have suggested the meta methodology for applying the ebXML framework to other industries.

This study aims to document empirically the mediating role of corporate social responsibility (CSR) on the influence of competitive pressure toward business performance on the batik industry in Central Java, Indonesia. This study also examined the effect of competitive pressure and CSR on business performance of small- and medium-sized enterprises (SMEs) in the batik industry in Central Java. This study used an explanatory quantitative approach. Samples of 254 MSEs in the batik industry have been successfully collected. Hypothesis testing uses SEM-PLS. The results of this study indicate that competitive pressure has a positive and significant effect on the batik MSEs business performance in Central Java. Competitive pressure also has positive direct effect on corporate social responsibility, and CSR has a significant and positive direct effect on business performance. The results of this study have successfully documented empirically that CSR has a mediating role on the relationship of competitive pressure toward business performance in the batik MSEs in Central Java, Indonesia. This study provides a comprehensive understanding of the owners of the batik MSMEs in coping with competitive pressure by using CSR as a strategy to create uniqueness that is difficult to imitate and can create an organizational reputation that eventually can increase business performance.

The paper attempts to document the application of relevant Machine Learning (ML) models on Yelp (a crowd-sourced local business review and social networking site) dataset to analyze, predict and recommend business. Strategically using two cloud platforms to minimize the effort and time required for this project. Seven machine learning algorithms in Azure ML of which four algorithms are implemented in Databricks Spark ML. The analyzed Yelp business dataset contained 70 business attributes for more than 350,000 registered business. Additionally, review tips and likes from 500,000 users have been processed for the project. A Recommendation Model is built to provide Yelp users with recommendations for business categories based on their previous business ratings, as well as the business ratings of other users. Classification Model is implemented to predict the popularity of the business as defining the popular business to have stars greater than 3 and unpopular business to have stars less than 3. Text Analysis model is developed by comparing two algorithms, uni-gram feature extraction and n-feature extraction in Azure ML studio and logistic regression model in Spark. Comparative conclusions have been made related to efficiency of Spark ML and Azure ML for these models.
