This study aims to take a look at `argument relation` in the `의`-noun phrase and its distribution. For this research a small-scale corpus was constructed, and the corpus includes both the spoken language and the written language. The article `의` is used to connect the front component(NP1) and the rear component(NP2) to form a noun phrase, which is called `uy`-Noun Phase in this study. There are a lot of the semantic relations between the NP1 and the NP2 in the `의`-Noun Phase, but the `argument relation` is taken a look at only as the subject of this study. The `argument relation` could be classified into a case where the predicative noun comes in the place of NP2(as `agent`, `theme`, `condition`) and a case where it represents the `subject as a meaning`. In the usage distribution, `agent` and `theme` which were of not of high notice till now, each showed relatively high shares of 11.9% and 9.2%. Especially the `theme` showed a considerable difference between written language and spoken language.

This study evaluated very recent situation of transforming defense engineering methodology from system engineering to digital engineering in the developed countries’ defense organizations because they tried to utilize the maximum extent of digital technology from 4th industrial revolution into weapon systems thru TLC(Total Life Cycle) from capability analysis, design and manufacturing, operation and sustainment, and suggested a few recommendation how to adopt the digital engineering into our nation.

자립 운전시 전력조절기는 일반적으로 태양광 발전에서 사용을 할 경우 부하에 의해 출력이 결정되어 최대전력 추종을 할 수 없는 구조로 되어있다. 본 연구에서는 자립 운전시의 태양광 발전시스템이 안정적인 최대전력 추종을 할 수 있도록 에너지 저장장치가 결합된 구조를 제안하였다. 이러한 구조에서는 태양광 발전의 전력 손실을 줄이고 또한 태양광 발전 전력이 부족할 경우에서도 부하 측의 안정적인 동작을 보장하기 위하여 에너지 저장장치와 DC-DC 양방향 컨버터를 이용한다. 에너지 저장장치의 한 예로 슈퍼커패시터를 충·방전함으로써 태양광 발전 에너지에 의한 안정적인 출력을 낼 수 있고, 태양광발전 전력의 효율적인 사용을 위한 전력조절 시스템의 아키텍처를 제안하고자 한다.

Energy storage devices are necessary to obtain stable utilization of renewable energysources. When black-out occurs, distributed renewable power sources with energy storage devices canoperate under standalone mode as uninterruptable power supply. This paper proposes a dynamicresponse analysis with small-signal modeling for the standalone operation of a photovoltaic powergeneration system that includes a bidirectional charger/discharger with a battery. Furthermore, itproposes a DC-link voltage controller design of the entire power conditioning system, using thestorage current under standalone operation. The purpose of this controller is to guarantee the stableoperation of the renewable source and the storage subsystem, with the power conversion of a veryefficient bypass-type PCS. This paper presents the operating principle and design guidelines of theproposed scheme, along with performance analysis and simulation. Finally, a hardware prototypeof 1-kW power conditioning system with an energy storage device is implemented, for experimentalverification of the proposed converter system.
