최근 마이크로서비스 아키텍처가 널리 채택되면서 다양한 애플리케이션들이 클라우드 네이티브 환경에서 운영되기 시작하였다. 그리고 이러한 서비스의 보안을 강화하기 위해 서비스 메시를 활용하여 클라우드 서비스 간의 암호화 통신을 구현하였다. 하지만, 양자 컴퓨팅의 등장과 함께 기존 암호화 방식이 취약해질 수 있다는 가능성이 제시되었다. 이에, 클라우드 네이티브 환경에서도 암호화 기술이 빠르게 변화할 수 있는 유연성, 즉 암호화 민첩성(Cryptography Agility)의 중요성이 강조되고 시작하였다. 본 연구에서는 서비스 메시 환경에서 암호화 민첩성을 실현하는데 있어 현 서비스 메시 솔루션들이 직면한 구조적 한계를 분석하고 이에 대한 해결 방안을 제시하고자 한다. 특히, 대표적인 서비스 메시 솔루션인 Istio 에 초점을 맞추어 암호화 민첩성을 향상시키기 위한 개선 방향을 제안하고자 한다.

An authentic simulation platform for events situated in spatio-temporal space is presented. The authenticity, i.e., logical fidelity to the reality, of this cyberspace is realized by maximizing the diversity and unpredictability of events occurring therein. The knowledge components and associated schemes required for the simulation of events situated in spatio-temporal space encompass the environmental factors, the objects, the events, and their interrelations. We deviled event activation, triggering mechanism, and cognitive function related to event to realize an authentic simulation of discretionary events. The agents in this simulation environments are autonomous in that they have their own existence and capability of event planning. We focused on identifying basic constructs relevant to authentic simulation of discretionary events whose initiation depends on human intention. Several key ideas are implemented in a typical spatio-temporal situation to demonstrate the viability of our simulation mechanism.

Actually, The present traffic accident detection system is subsisting limitation of accurate distinction under the crowded condition at intersection because the system depend upon mainly the image information at intersection and digital image processing techniques nearly all. To complement this insufficiency, this article aims to estimate the level of present technology and a realistic possibility by analyzing the acoustic characteristic of crash sound that we have to investigate for improvement of traffic accident detection rate at intersection. The skid sound of traffic accident is showed the special pattern at $1[kHz]{\sim}3[kHz}$ bandwidth when vehicles are almost never operated in and around intersection. Also, the frequency bandwidth of vehicle crash sound is showed sound pressure difference over 30[dB] higher than when there is no occurrence of traffic accident below 500[Hz].

Nowadays, smart phone became an important part of communication media and integrated into people's life. If callers rely on helmet-mounted display(HMD) augmented reality technique to add two-way user's facial expression, appearance, actions during the calling process, it will let callers have a visualized fantastic sensual experience. And through that method can break the limitations of vision, so research that technical problem can promote the development of visual arts, that is meaningful. This paper will choose and composite several existed technologies to set up two hypothesis, try to realize AR video calling. Through comparison and analysis to find those two hypothesis' problem, and create design solutions to solve problems. And use case study method to present two cases for prove my paper's result that is those two hypothesis can be realize in future. Use those technologies can bring more convenience and enjoyment to people's life. It can be predicted that AR video calling process can be successfully realized and will have unlimited development in future.

In this paper, we propose a system that can provide a environment for plant cultivation in connection with LED plant factories and enable users to participate in plant cultivation remotely to engage in personal hobbies. The proposed system can monitor the growth conditions of plants through various sensors and remotely adjust the cultivation environment required for plant growth through the Arduino system, so that users can feel the satisfaction of plant cultivation and harvesting as a hobby. On the other hand, we suggest a mutual benefit structure for plant factory and users by securing a certain amount of income source to factory, by paying the idle space to the individual online. This paper demonstrates the feasibility of the proposed system by making the prototype of the remote plant cultivation consignment system using the Arduino and Android application(App.), and contributes to popularize the LED plant factories and expand the business area in future.

In this study, in the high expansion cycle was conduced by variable valve timing system composition to close intake valve late, and in the intake air reduction on the low compression was solved by supercharging pressure. In this wise, by constituting Diesel-Atkinson cycle, this study looked into a possibility of thermal efficiency improvement. As a result, there was improvement in thermal efficiency and output in a whole range of closing timing from ABDC $40^{\circ}$ to ABDC $80^{\circ}$. However, after ABDC $70^{\circ}$ of closing timing, the thermal efficiency increase was getting smaller. As the result of the study, the optimum intake valve closing timing was about ABDC $70^{\circ}$, high loading territory of engine was more effective than low loading territory, and engine operation in middle loading territory was stable. At this time, brake thermal efficiency was 12.5% higher than ordinary engine on average.

In this paper, we attempt to realize the diversity of human actions in a virtual world in terms of the basic actions. We utilize the comprehensive knowledge structure of ontology to organize the human actions into an action hierarchy, each action being the root action of its associated hierarchy of specialized actions. Each basic action is implemented by composing the primitive motions and each basic action in turn by reusing those basic actions. Our approach to the development of these actions is focused more on their diversity and brevity than on their visual realism. Based on this design we develop a method to grasp virtual humans' characteristics and reflect those characteristics on their respective action patterns. We also present a mechanism for the agents to adapt their motions to diverse qualitative changes in environment. We apply these methods to such basic actions as walk, run and throw to demonstrate their viability.
