Multidisciplinary Design Optimization (MDO) is an optimization technique considering simultaneously multiple disciplines such as dynamics, mechanics, structural analysis, thermal and fluid analysis and electromagnetic analysis. A software system enabling multidisciplinary design optimization is called MDO framework. An MDO framework provides an integrated and automated design environment that increases product quality and reliability, and decreases design cycle time and cost. The MDO framework also works as a common collaborative workspace for design experts on multiple disciplines. In this paper, we present the architecture for an MDO framework along with the requirement analysis for the framework. The requirement analysis has been performed through interviews of design experts in industry and thus we claim that it reflects the real needs in industry. The requirements include integrated design environment, friendly user interface, highly extensible open architecture, distributed design environment, application program interface, and efficient data management to handle massive design data. The resultant MDO framework is datasever-oriented and designed around a centralized data server for extensible and effective data exchange in a distributed design environment among multiple design tools and software.

Arduino is used in various places such as education, experimentation, and industry. Due to the easy accessibility of Arduino, it is often used by non-majors, and it is also used in media art and toy programs. Although Arduino is relatively easy to use compared to other devices, it is not easy to control various IoT components at the same time. Some tasks run independently of other tasks, while others run dependently. In this paper, I proposed the Arduino Task Framework to efficiently execute many tasks in these various situations. The design framework of this paper is largely composed of two types: synchronous execution and asynchronous execution. These two execution methods can be combined to create several independent and dependent execution routines. Asynchronous tasks are independently executed tasks and are managed by AsyncTaskGroup, while synchronous tasks are dependently executed tasks and are managed by SyncTaskGroup. AsyncTaskGroup instance and SyncTaskGroup instance are instances of the same Task and can be used in combination with another task. The Arduino framework proposed in this paper simplifies the program structure and can easily compose various tasks.

The increasing demand of users for various wireless communication services has lead to the development with uniting co-existence of different and wireless networks. Each one of the these wireless networks has its own unique characteristics, as compared to other networks. An integrated security mechanism is one of the key issue in the open wireless network. To realize overall security mechanism in open wireless architecture, we should provide practical workable framework for the realization of the integrated security challenges. In this paper, we analysed integrated security platform and considerations based on the security concept.

Although open innovation (OI) has been an important research theme for over a decade, its theoretical framework has been relatively under-researched. As OI involves a wide range of innovation activities, a firm's capacities in the use of the various firm resources play a critical role in OI implementation. However, it is unclear how they affect firms' performances for little is known of OI capacities. Based on a theoretical framework derived from the literature, this study looks into the relationships between six OI capacities (inventive, absorptive, transformative, connective, innovative, and desorptive) and financial performance using the Korean Innovation Survey (KIS) 2008 data. The research model was tested using structural equation modelling (SEM) while potential differences in capacities between different firm groups were also investigated. The results indicate that 1) OI capacities are significantly associated with firms' financial performance; 2) capacities are highly correlated with one another; and 3) some capacities are differently configured between different types of firms. Findings suggest that policy makers should pay more attention to helping firms enhance OI capacities and attempt to develop relevant policies in order to complement inadequate capacities.

IPTV hasn't fulfilled the expectations that it will substitute existing digital broadcasting service and serve new type of services such as interactive and multi-channels. Today's IPTV service just seems to change existing service platform to new one. In this situation, Open IPTV service has been on the rise, which make it possible for consumers to choice contents regardless of contents providers. However, the integration of variety service platforms such as rights protection solution is essential to provide Open IPTV service. In this paper, authoring and consuming system for package contents based on MPEG-21 Multimedia Framework which is developed for distributing media resources.

In this study, factors necessary for successful industry-university cooperation of SMEs(small and medium-sized enterprises) were identified. The structure of the TOE (Technology, Organization, Environment) framework was considered for a company's industry-university cooperation preparation capacity, and open innovation collaboration and resilience were utilized as a mediating effect between industry-university cooperation preparation capacity and corporate performance. This study verified the model through a structured questionnaire targeting 204 SMEs with industry-university cooperation experience. As a result, it was confirmed that it was important for companies to make diversified efforts by accommodating industry-university cooperation to obtain results from industry-university cooperation.

정보통신 기술의 발달로 무분별한 사이버 공격에 노출되어 있기 때문에 정보보안의 기술이 중요해지고 있다. 이중 침입 탐지 시스템은 방화벽과 더불어 시스템 및 네트워크 보안을 위한 대표적인 수단으로, 현재까지 네트워크 기반인 NIDS와 호스트 기반인 HIDS에 대한 많은 연구가 이루어졌다. 이러한 침입 탐지에 대한 CTI(Cyber Threat Intelligence)를 공유하기 위해 다양한 CTI 프레임워크를 사용하여 CTI 정보를 공유하는 연구가 진행되고 있다. 이에 본 논문에서는 CVE기반의 OpenIOC와 Snort 및 OSSEC에서 생성된 Raw Data를 결합하여 새로운 CTI 프레임 워크를 제안한다. 제안된 시스템을 테스트하기 위해서는 CVE 분석을 기반으로한 Kali Linux로 공격을 진행한다, 이를 통해 생성된 데이터는 시간이 지남에 따라 축적된 데이터를 저장 및 검색을 위해 대규모 분산 처리 시스템과도 결합이 필요할 것으로 예상되며 추후 딥러닝 기술을 활용하면 지능형 지속 위협을 분석하는데 용이할 것으로 예상된다.

In this paper, we implemented a FIPA-OS multi-agent framework bundle in OSGi Service Platform. FIPA-OS is an open agent platform for constructing FIPA compliant agent using mandatory components that required by all FIPA-OS agents to execution and optional components that FIPA-OS agent car optionally use. The platform supports communication between multiple agents and communication language which conforms to the FIPA standards. FIPA-OS framework bundle is composed of DE(Directory Facilitator), AMS(Agent Management System), ACC(Agent Communication Channel) and MTS(Message Transport System) bundle. These bundles installed in the OSGi service platform and their life cycle can be managed by the framework.

In this paper, an interactive planning and scheduling framework are proposed for optimising operations from pits to crushers in ore mining industry. Series of theoretical and practical operations research techniques are investigated to improve the overall efficiency of mining systems due to the facts that mining managers need to tackle optimisation problems within different horizons and with different levels of detail. Under this framework, mine design planning, mine production sequencing and mine transportation scheduling models are integrated and interacted within a whole optimisation system. The proposed integrated framework could be used by mining industry for reducing equipment costs, improving the production efficiency and maximising the net present value.
