최근 IT 산업 전반에 걸쳐 모바일에 대한 중요도가 높아짐에 따라 인터넷 브라우저의 성능이 중요하게 되었다. 자바스크립트 언어의 수행은 인터넷 브라우저의 사용에 있어 상당히 비중이 높다. 이 논문에서는 자바스크립트 언어를 수행하는 엔진 중 하나인 TraceMonkey엔진이 트레이스를 하는 과정에서 생기는 오버헤드를 줄이는 최적화를 구현, 적용하고 이를 실험하여 평가한다.

The blister packaging is applied to many fields in recent years for its merit that it enable consumer to see the products. The most of battery packaging are blister type. However, the lithium battery is dealt with very carefully in packaging because of its explosion. The existing packaging machines for lithium battery are mostly adapted alkaline packaging machine and their capacity is very inferior to other process, either. In this paper, the virtual prototype of the automatic blister packaging system for lithium battery which has new mechanism and 240A/min capacity is developed and its performance is evaluated.

When replacing hardware due to obsolescence, discontinuation, and expansion of software-equipped electronic equipment, software changes are required in the past, but if virtualization technology is applied, it can be applied without software changes. In this regard, we studied in order to apply virtualization technology in the development of naval multi-function radar signal processing, we studied hardware and OS independency for Docker and performance comparison between Docker and virtual machine. As a result, it was confirmed that hardware and OS independence exist when using Docker and that high-speed processing is possible compared to the virtual machine.

We studied the technique which can control the real system without additional hardware drivers using virtual machine driver operated on the windows operating system. We showed the feasibility of the proposed scheme under the error and the delay of a sampling time on the multi task processing through the load test of the experiment using graphic user interface.

In Part 2, dynamic cutting force model, thermal behavior model, and feed drive model are presented for development of a virtual machine tool. Some relevant results with brief descriptions for each model are presented to verify the proposed models. Experimental results for each model agreed well with the estimated ones. The developed models in this two-part paper are partially integrated as a comprehensive software environment.

In Part 2 of this paper, the dynamic cutting force model, thermal behavior model, and feed drive model used in the development of a virtual machine tool (VMT) are briefly described. Some results are presented to verify the proposed models. Experimental data agreed well with the predicted results fer each model. A comprehensive software environment to integrate the models into a VMT is also proposed.

최근들어 IT 산업이 급속도로 발전하면서, 리소스가 제한된 작은 기기들의 사용이 비약적으로 증가하는 추세에 있다. 이들 기기들에 플랫폼 독립성(Platform Independency), 보안성(Security), 이동성(Mobility) 등의 장점을 포함하고 있는 자바 환경을 적용하려는 연구가 계속되고 있는데, 자바 환경의 핵심인 자바가상머신(Java Virtual Machine: JVM) 임베디드 시스템이나 모바일 시스템과 같이 작고, 자원이 제한적인 장치에 탑재하기에 너무 큰 용량(footprint)을 차지한다. 이를 해결하기 위해 좀더 경량화한 가상머신이 필요하였다. 본 논문에서는 네트워크 연결 능력이 있고 적은 리소스를 가진 다양한 기기들에 적합한 최소 크기의 표준 자바 플랫폼에 대한 Configuration 인 CLDC(Connected, Limited Device Configuration)에서 정의하고 있는 K가상머신(K Virtual Machine: KVM)에 대해 분석하고 설계한 내용을 기술하고 있다.

본 논문에서 재목적 기술을 이용하여 임베디드 시스템상에 가상기계를 효과적으로 탑재할 수 있는 방법을 설계한다. 이를 위해 가상기계를 플랫폼 독립적인 요소와 플랫폼 의존적인 요소로 구분한 후 플랫폼 의존적인 부분을 재목적 기술을 적용하여 어댑터를 설계하고 구현하였으며 이를 증명할 수 있는 정형화된 방법을 제시하였다.

To quickly determine the effect of the substitute component on the machine's performance is very important in the defign and the manufacturing processes. And minimizing machine cost and maximizing machine quality mandata predictability of machine accuracy. In the study, in order to evaluate the effects of the component's geometric errors and dimensions on the machining accuracy of gantry-type 5-axis machining centers, a geometric error analysis and virtual manufacturing system is developed based on the mathematical model for the shape generation motion of machine tool considering the component's geometric errors and dimensions, the solid modeling techniques and so on.

In recent days, as the efficiency of electronic home applications become higher, that of the driving AC motor become higher. On this reason, the demand fir high capacity coil firming machine is increasing. Since the coil forming is not simply related with the only capacity of hydraulic cylinder, the development of a newer coil firming machine which has new filming mechanism new driving method, new filming tool, and new specification is required. In this paper, the virtual prototype which have new mechanism is developed. This prototype is tested and experimented on PC with the same condition as actual. The results from the virtual experiment is applied to the actual design process.
