Six sigma is an innovative management movement which provides improved business process by adapting the paradigm and the trend of market and customers. Suitable selection of six sigma project could highly reduce the costs, improve the quality, and enhance the customer satisfaction. There are existing studies on the selection of Six Sigma projects, but few studies have been conducted to select the correct project under an incomplete information environment. The purpose of this study is to propose the application of integrated MCDM techniques for correct project selection under incomplete information. The project selection process of six sigma involves four steps as follows: 1) determination of project selection criteria 2) calculation of relative importance of team member's competencies 3) assessment with project preference scale 4) finalization of ranking the projects. This study proposes the combination methods by applying group fuzzy Analytical Hierarchy Process (AHP), an easy defuzzified number of Trapezoidal Fuzzy Number (TrFN) and Grey Relational Analysis (GRA). Both of the weight of project selection criteria and the relative importance of team member's competencies can be evaluated by group fuzzy AHP. Project preferences are assessed by easy defuzzified scale of TrFN in case of incomplete information.)

In domestic construction industry, CM companies perform overall project management tasks such as planning, designing, construction management, evaluation, maintenance for construction projects. However, even with these tasks, as competition becomes more fierce and probability dependence is high, lots of CM companies are experiencing difficulties of securing and preparing indicators for order competence reinforcement. This study examines domestic business condition and task analysis. Also Competence factors are derived through institutional and legal investigation, and review of existing literature. The derived competence factors are focused on practical factors by interviewing with experts. competence factors for each type were classified into BSC's four perspectives(Finance / Customers / Internal processes / Learning and Growth) and surveyed. Based on the results of the survey, the priorities of competence factors that companies should focus on were derived. The purpose of this study is to contribute on making an indicator that can be utilized on business activities through priority analysis of competence factors for order competitiveness reinforcement of CM companies.

A new revenue recognition standard was adopted in 2018. The purpose of this paper is to analyse how K-IFRS 1115 'Revenue from Contracts with Customers' affects the revenue recognition of the telecommunication firms and to suggest a regulatory policy for the telecommunications industry. It shows identifying performance obligations for bundles, determining the transaction price and allocating the transaction price to the performance obligation and how to account for it using case study. The most important change in the telecommunication companies's revenue is to allocate the transaction price to two performance obligations: telecom services and mobile handset sales. As a result, sales revenue are expected to drop en masse. This study provides important implications for the regulatory accounting policy of the telecommunications industry.

Recently, way of Electronic Commerce is changing with increment of Internet users. In the previous way of commerce, users used to search for information by themselves. However, for user's convience, it can be done for users from one site. Mobile in order to provide users with such service. By the mobile agent-based Electronic Commerce system, users can get information from one site, and service companies can provide various and useful information to users. This is very important for construction of reliable Electronic Commerce environment, However, in generally used mobile agent-based platforms, the user should know URL information. and it is based on search engines. And as user's requirement levels become higher, they want to be provided with integrated and summarized service. In this paper, we implement product-trading system by applying mobile agent concept in order to satisfy user's requirement of getting required information from one site with minimal mouse click. For implementing the product trading system, E-speak, which is a platform for E-Service, is used And contents are saved as XML documents and data are shared based on these documents.

A cloud computing service provider must assure Service Level Agreement (SLA) to provide reliable and consistent quality of service to a user. The SLA is a contract between the user and the service provider that connects to assure constant level such as availability to target provided service. The cloud computing is classified into IaaS, PaaS, and SaaS according to IT resources of the various cloud service. The existing SLA is difficult to reflect quality factors of service because it only considers factors about the physical Network environment. In this paper, we suggest the UDDI-based interchange process with the architecture and the specification language having a XML schema for the SLA specification. The quality requirements of SaaS are defined by a proposed specification language in the cloud environment. It is stored in the repository of a quality specification and exchanged on during the service binding time based on the exchange architecture.

Currently in many places, such as a business or government office, customers are spending many time after issuing waiting number ticket. To improve this, this paper proposes new design of waiting number ticket issuing system which provides real-time notification service with smartphone. This system add the NFC tag to the issuing machine in order to input the information of waiting and increase the convenience of users and provides an integrated management of corporate and government information using a waiting number ticket. Therefore, it is possible to efficiently use the waiting time than when using the existing ticketing system by taking advantage of this system, and appears to be to reduce costs and environmental protection, by not using the paper ticket. Also this system can be used to improve business processes through the application Waiting Number Ticket ticket cancellation feature.

People constantly strive for better choices. For this reason, recommender system has been developed since the early 1990s. In particular, collaborative filtering technique has shown excellent performance in the field of recommender systems, and research of recommender system using machine learning has been actively conducted. This study constructs recommender system using collaborative filtering and machine learning based on stacking model which is one of ensemble methods. The results of this study confirm that the recommender system with the stacking model is useful in aspects of recommender performance. In the future, the model proposed in this study is expected to help individuals or firms to make better choices.

It easily collects information on purchased goods using IoT(Internet of Things). The collected data is updated directly to the smartphone for verification. The payment information is generated by QR-Code. As a way to implement a system, System was configured with two assumptions: IoT technology using Raspberry-Pi and mobile QR technology. First, RFID tags are attached to the goods instead of barcodes. Second, it has an IoT computer(Raspberry-Pi) built into its shopping cart. This system keeps traditional shopping method of face-to-face payment, but replace time-consuming tarditional barcode tagging method to QR-tagging system for time-efficiency. By debeloping the system of this paper, we maintain pleasures in offline store shopping and it provide convenience due to reduced waiting time for customers and providing prior information about the products.

Electronic cash system based on anonymous coins have been invented by David Chaum. However, von Solms and Naccache discovered that such anonymous coins also very well suited to support criminals in Blacoailing. In this paper, we suggest a method that a client informs a bank of the information about blackmailing attack by using Schnorr identification protocol of XTR version at the stage of identification, whenever he is blackmailed. In general, blackmailing is the most serious among the various drawbacks of electronic cash system. Especially, blackmiling to be done when the client is kidnapped brings a fatal result to electronic cash system. But if the Schnorr identification protocol of XTR version is used, we can efficiently defeat blackmailing without assumption required in the existing method to defeat blackmailing.
