『화랑세기』에 나타난 신라 여성의 사회적 지위와 활동

하현진 한국교육현상해석학회 2010 현상해석학적 교육연구 Vol.7 No.2

우리는 전통적인 여성상으로 가정의 테두리 안에서 온순하고 순종적으로 생활하는 여성상을 떠올리기 쉽다. 그러나 유교 여성이 강조되기 이전 신라 사회 여성들은 사회적 지위가 매우 높았고 공적인 영역에서도 활발히 활동하였다. 신라사회 여성들의 사회적 지위가 높았던 이유는 단군신화에 등장하는 풍백을 계승했기 때문이다. 풍백은 환웅과 더불어서 개벽실현에 참여 하며 환웅과 동등한 입장을 보여주었다. 이러한 풍백 의식을 신라사회는 풍신제를 지낸다든지 중국과 교류가 어려운 지정학적 요인으로 인해 잘 계승할 수 있었다.풍백의식을 계승한 신라사회 여성들의 사회적 지위와 활동이 어느 정도였는지는 화랑세기를 통해 알 수 있다. 신라사회는 마복자 제도, 사신, 삼서제를 통해 성적으로 매우 자유롭고 개방되어 있었으며 부부관계에서도 무조건적으로 여성들이 남성에게 순종하는 모습을 찾기 어렵다.미실은 색공을 통해 진흥왕, 진지왕, 진평왕을 모셨으며 직접 정치에 참여하기도 하였다. 풍월도와 관련해서도 여성들이 우두머리 원화가 되거나 풍월주의 부인 화주가 낭정에 직접 참여하거나 활동을 하였다. 풍월주의 임명도 왕이 아니라 여성들이 직접 하였다. 그리고 진골정통과 대원신통 경쟁을 통해 여성들은 권세를 장악해 갔으며 선덕왕 진덕왕 여왕이 왕위를 계승하기도 하였다.이렇게 화랑세기에 등장하는 인물과 사건들을 통해 풍백의식을 계승한 신라사회는 여성들의 사회적 지위가 매우 높았으며 여성들이 공적인 영역에서도 활발히 활동했음을 알 수 있다.

NOx Smoke and other exhausted components already became a dangerous state as principal materials of the air pollution. Therefore, the exhausted regulations are getting strict in the many countries. In this paper, reduction characteristic of NOx Smoke and CO from diesel engine are investigated, when MF plasma-EGR hybride system is put to the diesel engine NOx is decreased in all measured load and applied voltage to plasma reactor. However Smoke is increased as increasing EGR rate and it is decreased as increasing applied voltage. 디젤 자동차 배출 가스인 NOx Soot 그리고 기타 가스들은 주요한 대기 오염의 물질들이다. 그러므로 여러 많은 나라들이 이에 관련된 규제 법규를 점점 더 엄격하게 규제하고 있는 실정이다. 본 논문에서는 디젤 자동차에서 발생되어지는 NOx, 매연 그리고 CO를 고주파 플라즈마와 EGR 시스템을 조합하여 그 제거 특성을 연구하였다. NOx는 부하와 전압이 증가하게 되면 NOx는 감소하고 매연의 경우에는 EGR율이 증가함으로 인해서 증가 하였다. 그러나 전압이 증가함에 따라서는 감소하였다.

Background: The purpose of this study is to find out the effect on the improvement in idiopathic scoliosis when applying the orthopedic manual physical therapy and myofascial release technique. Methods: 20 patients in Cheon-An ${\bigcirc}{\bigcirc}$ hospital were selected as subjects whose Cobb's angle were higher than $10^{\circ}$ according to the radiograph. They were treated for 60 minutes a day, three days a week, and 8 weeks so that the total time of visit would be 24. We performed five tests (Moire test, X-ray, standing height test, Cobb's angle, pelvic level test, VAS) to indentifiy the therapeutic effects. Results: Four test results were improved more remarkably after those treatment than before(p<.001), except pelvic level test (p>.001). Conclusion: we confirmed that there were correcting effects on most of the valuation index from the primary analysis, which divided the subjects into 2 groups by Cobb's angle, but there were more effective in patients having lower than $25^{\circ}$. There were similarly correcting effects on most of the valuation index according to the secondary analysis, but there were particularly more effective in children.

The purpose of this study is to investigate the effect of hole or crack on the Insulation characteristics of a PET films for EHV(Extra High Voltage) VT winding. The hole or the crack in the PET films was made and the insulation characteristics of them were measured. Ad an experimental result, it was shown hat he PDIV(Partial Discharge Inception Voltage) and the BDV(Breakdown Voltage) of the PET films with hole or crack were lower than those without them, and were markedly dependent on their position and temperature. Therefore, the hole and the crack affected to insulation characteristics of PET films for SF$_{6}$EHV(Extra High Voltage) VT Winding.g.

고연료 중 대부분이 수소와 탄소의 결합물이다. 연료들은 엔진 내부에서 완전 연소되었을 경우는 수분인 증기와 $CO_2$가 발생된다. 그러나 대개 불완전 연소가 일어나 $NO_x$나 Smoke가 발생되어진다. 그리고 이 물질은 인해에 매우 해로운 물질들이다. 본 논문에서는 EGR과 상용주파수를 이용한 플라즈마 장치를 조합하여 배기가스 유해물질 제거 특성을 연구하였다. $NO_x$의 경우에는 전압과 EGR율이 증가할수록 유해물질 제거 특성이 우수하였고, Smoke의 경우에는 EGR 율이 증가하게 되면 Smoke의 발생율이 증가하였으나 전압이 증가하게 되면 발생율이 감소하였다. A great part of flint fuel is Hydrogen and carbon's combination, they should be generated steam and carbon gas when combine with oxygen for perfect combustion in the inside of engine but, the pollutive material are discharged, even though perfect combustion condition especially $NO_x$ and Smoke. they are really harmful for health. In this paper was shown the result of discharging gas' reduction quality. which used combination of corona discharge using the high voltage source of common frequency with EGR. $NO_x$ is increased in entire load erea in proportion to increasing of EGR rate and impression voltage. Smoke is increased slowly under 75[%] in load rate but it is increased rapidly in entire load erea and the reduction rate of Smoke is increased in proportion to increasing of impression voltage.

Purpose : The purpose of the research was to analyze foot pressure, foot temperature, and correlation between foot pressure and foot temperature to grasp impact on foot pressure and body temperature distribution chart depending on functional difference of leg length. Method :: After measuring leg length, put 15 students whose functional difference of leg length was over 10mm to difference group and 15 students whose functional difference of leg length was under 5mm to normal group and categorize soles of foot into 6 sections of hallux head, 1st metatarsal head, 2-4 metatarsal head, 5 metatarsal head, lateral heel, and then measure by foot pressure analyzer to analyze characteristic of pressure distribution and classify into front of the lower leg, back of the lower leg, soles of foot and measure by body temperature analyzer to analyze by checking body temperature. Result : Weight difference depending on foot pressure and body temperature was bigger when functional difference of leg length was bigger, and it could be confirmed that foot pressure and body temperature of short leg side were higher than those of short leg side. Thus, if difference exists in leg length, weight load on short leg side increases which results in higher foot pressure and body temperature, therefore enabling an assumption that mechanical problem will occur in short leg. Conclusion : When functional leg length inequality, weight bearing and pressure was getting high as a result, temperature was getting high in short leg.

The effects of non-thermal plasma reactor and recirculated exhaust gas on performance and exhaust emissions under four kinds of engine loads were experimentally investigated by using a four-cycle, four-cylinder, swirl chamber type, water-cooled diesel engine with a combined plasma EGR system operating at three kinds of engine speeds. The purpose of this study is to develop the combined exhaust gas recirculation(EGR) control system with a non-thermal plasma reacto for reducing NOⅹ and soot emissions simultaneously in diesel engines. The EGR system is used to reduce NOⅹ emissions, and the non-thermal plasma reactor is used to reduce soot emissions. The plasma system in this study is a flat-to-flat type reactor operated by a plasma power supply. The experiments arc performed at the fixed fuel injection timing of 4˚ ATDC regardless of experimenlal conditions. It is found that NOⅹ and soot emissions are decreased, especially soot emissions are markedly reduced at the middle loads, as the applied electrical voltage of plasma reactor is elevated.<br/>

The solenoid valve used in a submarine direction control system consists of a solenoid coil, a coil core, a housing surrounding the outer of the coil, and a plunger as a driving part. The solenoid valve is a device that uses the magnetic force generated from the applied power to move the plunger, the driving part inside the valve, to control the flow of fluid. Therefore, the magnetic properties and structure of each part of the solenoid valve greatly affect the performance of this valve. In this paper, considering the material characteristics of each part of the solenoid valve, the design of the solenoid valve for a submarine direction change and the electromagnetic finite element numerical analysis applying the two-dimensional axisymmetric shape were performed.
