According to arriving convergence environment which can create new value-added converged between industry and ICT technology, It has made economic growth and improve the quality of life. However this convergence environment provide not only advantage but also various security problems resulting from generating converged security threats. For resolving this security problem, we need to approach to security problem in the integrated view not the fragmentary view which cover only technical approach. So This study developed security governance framework which can manage trustful security governance in multidimensional view which cover strategy, managerial/operational and technical view. Therefore this framework can construct trustful security management system which can help top management team to engage in security management directly and organizational member to perform security activities and have responsibility for themselves as suggesting single standard for security management.

최근 기후변화 및 이상기후로 인해 하천환경 또한 급격하게 변화되고 있다. 변화되는 지구환경에 대응하기 위해 하천환경 대책과 하천생태계 보전/복원, 생물 보호, 친수기능 강화를 요구하고 있는 실정이다. 더욱이 소하천 건천화 및 하천환경관리에 대한 중요성은 대두되고 있으나 비용 및 인력투입 문제로 수위나 유량 등의 기초자료인 수위-유량 계측기술 및 대응연구가 미미한 실정이다. 체계적인 하천관리를 위해서는 신뢰성 있는 대상 하천의 수리량 자료 확보가 기본으로 요구된다. 이러한 중소하천의 관리의 신뢰도를 높이기 위해서는 실시간 수위유량 자료 확보가 필수적이다. 현재 하천 정비 계획 단계에서 수문모델링을 통해 중소하천의 유량을 산정하고 있지만 산발적으로 측정한 자료로는 검/보정에 한계가 있으며, 신뢰도를 확보하기 어려운 실정이다. 이수, 환경, 생태 등의 관점에서는 평상시 유량에 대한 실시간 정보가 매우 중요하다. 이에 체계적인 하천관리를 위해서는 중소하천에 대한 실시간 수리량 자료를 경제적으로 확보 할 수 있는 장치 개발 및 현장적용이 시급하다. 본 연구에서는 하천 횡단구조물이 가지고 있는 유량 측정의 편이성을 최대한 이용하여 급성장하고 있는 영상분석기술과 IT을 하천공학분야에 접목하여 중소하천의 수위와 유량을 실시간으로 원격 측정하는 WIA (Wireless Image Acquisition) 시스템을 개발하였다. WIA 시스템은 라즈베리파이 기반으로 적외선카메라를 이용하여 일정한 시간간격으로 횡단구조물의 상류, 중류, 구조물 주위의 흐름 영상을 확보하여 중앙처리장치로 전송하는 시스템으로 구성된다. WIA 시스템에서 전송된 영상은 본 연구에서 개발한 영상판독 S/W 및 H-Q 산정 S/W를 통해 하천의 수위를 판독하고 실시간으로 하천단면 수위유량 산정 자료 구축하는 자료로 활용된다. 현재 WIA 시스템의 성능 및 개선과 영상판독 S/W 및 H-Q 산정 S/W서버와의 연계운영 성능 평가를 통해 장치를 검증하는 단계에 있으며, 추후 서버구축을 통해 홍수 예 경보와 하천수질관리를 위한 기초자료로 활용될 것으로 기대된다. 또한 본 연구에서 개발하는 유량측정 시스템을 적용하면 기존 장비의 약 15% 예산으로 실시간 수리량 자료를 확보할 수 있을 것으로 예상된다.

With the rapid development in network, graphic technology, and digital technology, content industry is emerging as an important industry for new cultural development and economic development. The development in digital content technology has remarkably expanded the generation and distribution of contents, thereby creating new value and extending into a large distribution market. However, the ease of distribution and duplication, which characterizes digital technology, has increased the circulation of illegal contents due to illegal copying, theft, and alteration. The damage caused by this illegal content is severe. Currently, a copyright protection system targeting online sites is available. By contrast, no system has been established for offline companies that sell offline genuine content, which compete with online companies. The demand for content of overseas tourists is increasing due to the Korean wave craze. Nevertheless, many offline content providers have lost competitiveness due to illegal content distribution with online companies. In this study, we analyzed the case and status of similar copyright certification systems in Korea and overseas through previous research and studied a system to certify the offline genuine contents business. In addition to the case analysis, we focused on interviews obtained through in-depth interviews with the copyright stakeholders. We also developed a certification framework by establishing the certification domain, certification direction, and incentive of the certification system for offline businesses with genuine content. Selected certification direction is ethical, open, inward, store, and rigid (post evaluation). This study aimed to increase awareness among consumers about the use of genuine content and establish a transparent trading order in a healthy content market.

A basic function of packaging is preservability, delivery, subdivision, aesthetic and serviceability on packaging. Originally, the function and necessity of packaging is on preservability, but today it is expending before. then packaging is focusing on sales promotion. Although it is hard to say production itself, it could does when it is made. also, it is important for product to be goods when packaging and its materials are identification on matching each other. The role of packaging design is a core factor that satisfy consumer a various of needs and wants. In the past, the role of food packaging design is just preservability and delivery on product. but then, nawaday it is asked a various role. Not only present products have to get inherency but also have added value. That is, advanced technologies, information, and richness from materials which are diversity for coming a extention of choice. currently, food packaging design shouldn't have stayed on just packaging which cover beautiful. Packaging design is a symbolic sign. It is importance for manager to do R&D, producing, and distribution, also for consumer who use and buy the product whether manager and consumer think package design is a main mediation. This day, food design pay attention to be asking consumer's a number of sensitivity. It is the reason that the package is importance and exist. This article is to examine preservability, delivery, subdivision, aesthetic, serviceability, and environmental orientation in order to develop and show a method and theories to find package design in food industry the reason that why sales promotion and its profit increase. Consequently, draw on the function of package design effects the benefit on product is distribution. Green Design on the food packages by combining recycled and biodegradable food packages for the development of practices and long life to the look of the food package design practices.

Industrial insect is defined as the insect utilized in industries that creates added value. Most of the industrial insects used in Korea are exotic species that are introduced through artificial means. Despite the rapid expansion of market for industrial insects, the system for risk assessment of industrial insects is not being adequately conducted. Although Korea carries out a risk assessment for the species designated as disease and insect pest by Animal and Plant Quarantine Agency, far too little consideration is being given to overall ecosystem, as the control system is covered in the Plant Quarantine Law. To solve this problem, we analyzed the Korean risk assessment system and looked at systems in other countries. The results show that it is essential for stakeholders to reach an agreement to set up fundamental directions for the system. Unless the integration system of taxonomical and ecological information is prepared, the ecological risk assessment should be conservative to protect ecosystems and should also follow the precautionary principle. It also requires cooperation among the ministries. In addition, the results indicated that a differentiation between risk assessment and screening is urgent. Several solutions such as setting up clear objectives in both assessment and screening stages, target species, steering organization and assessment criteria assessment systems from were proposed as practical institutional strategies. Among many foreign countries the assessment system from Ireland equally considers various factors such as economical, ecological safety and management aspects, It is also based on precautionary principle to fulfil its original purpose. It was suggested that the Ireland system would be the best reference that can be modified and applied into the Korean system by considering distinct characteristics of the industrial insects.

This paper investigates the causal impact of the increase in institutional distance between two geographic regions on the flow of cross-border Venture Capital (VC) between the regions. While cross-border VCs are believed to have competitive advantages at identifying and managing promising startups in a local market compared to local counterparts, the discrepancy in institutional characteristics between two markets exacerbates the difficulty of credible information exchange and negotiation, significantly increasing transaction cost related to a cross-border venture capital investment. This study conducts a difference-in-difference analysis to examine the relationship between institutional distance and the flow of cross-border VC investment using the fact that the official adoption of the Euro currency by member countries of the European Union except the UK created an institutional chasm between the UK and other EU member countries. The outcomes of the analysis suggests that UK-based VCs significantly decreased the VC investment into EU-based startups and that EU-based VCs reduced the investment into UK-based startups. The results have meaningful implications for understanding the impact of the change in institutional difference on cross-border VC investment, which seems to increasingly take place with the recent trend of de-globalization and the rise of protectionism.

The wireless sensor networks have become an economically viable monitoring solution for a wide variety of civilian and military applications. The main challenge in wireless sensor networks is the secure transmission of information through the network, which ensures that the network is secure, energy-efficient and able to identify and prevent intrusions in a hostile or unattended environment. In that correspondence, this paper proposes a distributed clustering process that integrates the necessary measures for secure wireless sensors to ensure integrity, authenticity and confidentiality of the aggregated data. We use the notion of pre-distribution of symmetric and asymmetric keys for a secured key management scheme, and then describe the detailed scheme which each sensor node within its cluster makes use of the pre-distribution of cryptographic parameters before deployment. Finally, we present simulation results for the proposed scheme in wireless sensor network.
