In this paper the economic value of weather forecasts is valuated for profit-oriented enterprise decision-making situations. Value is estimated in terms of monetary profits (or benefits) resulted from the forecast user's decision under the specific payoff structure, which is represented by a profit/loss ratio model combined with a decision function and a value score (VS). The forecast user determines a business-related decision based on the probabilistic forecast, the user's subjective reliability of the forecasts, and the payoff structure specific to the user's business environment. The VS curve for a meteorological forecast is specified by a function of the various profit/loss ratios, providing the scaled economic value relative to the value of a perfect forecast. The proposed valuation method based on the profit/loss ratio model and the VS is adapted for hypothetical sets of forecasts and verified for site-specific probability of precipitation forecast of 12 hour and 24 hour-lead time, which is generated from Korea meteorological administration (KMA). The application results show that forecast information with shorter lead time can provide the decision-makers with great benefits and there are ranges of profit/loss ratios in which high subjective reliability of the given forecast is preferred.

In order for companies to survive rapidly changing business environment, it is expected that the activities in an enterprise must be reorganized around business processes; the information infrastructures are based on Web Services; and information systems are re-built around the BPMS (Business Process Management System). In this research we suggest major directions of e-business enhancement especially based on SOA(Service Oriented Architecture). Then we investigate the correlation between BPM functionalities and e-business technologies, and suggest priorities among the evolving directions of BPM functionalities via an intensive expert survey. The results of this study can be used by BPM solution vendors, prospective buyers and IT policy makers.

In these day, Digital Contents is authorized in forms of HTML and various kind of multi-media by an enterprise and/or organization. At this circumstances, it is very hard or impossible to search a contents between them. Futhermore, you may have to change your contents service systems to extend to cover more user services needs. On this paper, we propose a new architecture to get extendability and empowered interoperability without any maintenance, update or changes. And we introduce the OMG's CORBA to make fault resilient system and to provide a load balancing using a distributed process mechanism. Even more, we adopted the SyncML specification. It can help us to make it real to synchronize between DBMS at real-time. So all these are support easy content synchronization and user-friendness.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA(Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In particular, the integration of business processes and interfaces are important. Therefore, intuitive and easy to implement business process modeling is required. In this paper analyzes business process between enterprises, modeling the service-oriented business process with BPEL to realization level. Also, In this paper suggests that UML is used from high-level business problems to the process of low-level problem for Visual and effectively.

The Master Data is constructed for the wide use within the institution, and it is mainly used in the enterprise. In this research, we have conducted research for the purpose of building master data on infrastructure that can be used by public institutions in the country. To do this, we analyzed individual attributes of the standard data set provided by the public data portal. Among these, we extracted standard elements that match the characteristics of the Master Data. Finally, the standardized elements are verified through the standardization system that is utilized in the country.

Applications of unmanned aerial vehicles (UAVs) in the military environment have become popular because they require minimum human contribution and can avoid accidents during missions. UAVs are employed in various missions such as reconnaissance, observation, aggression, and protection. Consequently, counter-measures, known as anti-drone technologies, have been developed as well. In order to protect against threats from anti-drone technologies and enhance the survivability of UAVs, this study proposes an evasive measure. The proposed bio-inspired evasive maneuver of a UAV mimics a dragonfly's irregular flight. The unpredictable UAV movement is able to confuse enemies and avoid threats, thereby enhancing the UAV's survivability. The proposed system has been implemented on a commercial UAV platform (AR Drone 2.0) and tested in a real environment. The experiment results demonstrate that the proposed flight pattern has larger displacement values compared to a regular flight maneuver, thus making the UAV's position is difficult to predict.

오늘날 기업 내 ERP(Enterprise Resource Planing)시스템 도입이 활발해지고 있는 가운데 그 역기능으로 ERP 시스템 도입 실패 사례 또한 증가하고 있다. 이로 인해 ERP 시스템이 올바르게 구축되었는가를 판단하는 ERP 시스템에 대한 완성도 혹은 하자여부를 판단하는 감정평가 활동이 증가하고 있다. ERP 시스템은 일반적으로 패키지 형태의 프로그램과는 달리 비즈니스 프로세스 분석 단계에서 계약의 내용이 수정 및 확정되어지며, 업종 및 국가별 비즈니스 프로세스 특성에 따라 일반화된 모듈 프레임 워크를 그대로 적용하기 어려운 점을 가지고 있다. 따라서 본 연구에서는 ERP 시스템 완성도 감정평가를 위해 국내외 ERP 시스템에 대한 기본구조와 함께 세부적인 (공통/상이)모듈에 대해 정리를 수행하고, 이를 대상으로 핵심적인 비즈니스 업무수행을 위한 세부적인 절차를 추출하고자 한다. 본 연구를 통하여 제시된 ERP 시스템 감정 절차는 ERP 시스템 감정을 위한 기초자료로 활용될 수 있다.

Purpose - With the rapid development of information technology, the digital economy has become an important grip of the new development pattern, and the digital transformation of enterprises is a major trend. As SMEs are the mainstay of the economy and employment, it is important to study the digital transformation of SMEs to promote the development of the digital economy. Research design, data, and methodology - Based on a resource-based view, this report analyses the current situation and issues of digital transformation of SMEs from the perspective of digital orientation as well as the breadth and depth of technological capabilities of enterprises, using data from a survey of 200 manufacturing enterprises in China. Result - The results show that SMEs generally have a digital transformation mindset, but a weak digital foundation. In order to execute a digital strategy, companies need digital transformation capabilities. These behavioral capabilities are guided by the strategic direction of the business, and companies with strong capabilities are always trying to tap into the full digital potential. Conclusion - In order to effectively promote the digital transformation of SMEs, we suggest that SMEs pay attention to digital capability building, make good use of digital platforms and network resources, and lay a solid foundation for digital transformation; meanwhile, we suggest that government departments play a guiding and supporting role to build a cross-industry and cross-sector digital synergy system to help promote the development of SMEs' digital transformation. This paper presents some suggestions from both the internal and external environment of the enterprise, with the expectation of contributing to the digital transformation practices of SMEs.

Most electronic chassis control systems until today have been designed with optimization on its own performance. However, According to the increase of the interest regarding a vehicle safety and development of information technique, the integration technique of current chassis systems is being emphasized. Each enterprise proposed it with name of GCC(Global Chassis Control) or UCC(Unified Chassis Control). This study realizes control algorithm of suspension and brake by using the vehicle model of low degree of freedom as the primary stage of realization of integrated chassis control system. The proposed algorithm build the simulation environment connected to the CarSim having full vehicle model of 27 degree of freedom for raising the thrust of results
