This study aims at considering types of speaking/writing attitudes appearing in Hyangga and searching for ways about integrated Korean language teaching which the revised 7th curriculum demands. Communication structure inside Hyangga consists of streams of a speaker in a work-messages-a listener in a work. A Speaker's speaking and writing attitudes toward a listener appearing in Hyangga form four types such as persuading, enforcing, acknowledging, neglecting, and etc. Four functions, that is, persuading, enforcing, acknowledging, neglecting of speaking/writing types appearing in Hyangga is divided into two categories-a listener superiority and a speaker superiority. Persuading and acknowledging lower a speaker and at the same time raise a listener. On the other hand, enforcing and neglecting make a speaker predominant over a listener. In the linguistic expression, persuading and enforcing use the subjunctive mood, but acknowledging and neglecting don't use it. For the purpose of teaching expression ways which have intimate relevance to expression contents in the Korean language teaching, it is necessary to aim at integrated education of contents elements in the realms or between the realms based reading, we can utilize the speaking/writing types appearing in Hyangga even in the modern Korean language teaching. Through the activities we can compare the phases of the times with those of modern times and find various solutions about some problematic situations.

This study proposes a novel structure for the cross-eye, one of the representative jamming techniques of monopulse sensors. The proposed jammer tranceivers are composed of multi-channels with phased array antenna. We named this structure PRCJ(Phased array Retrodicetive Cross-eye Jammer). In this structure, formulas for calculating cross-eye gain and distance error are derived. We compare the properties of PRCJ with two-element retrodiredtive cross-eye jammer(TRCJ). PRCJ can achieve higher J/S because this structure can steer the spatially combined jamming signal in the direction of the incident monopulse signal. Because of the multiple channels in the phased array, it also increases the degree of freedom of channel matching. Finally, We preform a statistical analysis of the cross-eye gain according to the amplitude and phase errors. From this results, It has been found that PRCJ can get higher cross-eye gain than TRCJ.

모노펄스 센서는 수신된 단일 펄스마다 목표물의 각도를 추정한다. 이러한 모노펄스 센서의 각도 추정을 기만하기 위한 방법으로는 크로스 아이 기법이 효과적인 것으로 알려져 있다. 본 논문에서는 크로스 아이 기법의 각도기만 성능을 확인하기 위해 무반향 챔버에 모노펄스 수신 안테나와 크로스 아이 송신기를 이용해 각도기만 시험 환경을 구성한 결과를 소개한다. 그리고 시험 구성을 이용하여 두 개의 크로스 아이 송신기 간격을 변화시키면서 모노펄스 수신 안테나에 인가되는 합 신호와 차 신호의 크기를 측정하고, 그에 해당하는 각도기만 성능을 분석한다. A monopulse sensor is used to estimate the angle of a target with respect to each received single pulse. It is well known that the cross-eye technique can result in an angle deception effect against monopulse sensors. To verify this effect, we propose a test environment configuration for the angle deception using monopulse receiving antennae and cross-eye transmitters in an anechoic chamber. Using the proposed test environment configuration, we have measured powers of the sum and difference of the signals received by the monopulse receiving antennae when the distance of the two cross-eye transmitters is varied. Finally, the angle deception performance related to the powers of the sum and difference signals was analyzed.
