The initial situation in our tale shows that the earth-mother-feminine principle disappeared from the center of the collective consciousness into the collective unconscious. Therefore the heaven-father-masculine principle is dominant, which is represented by the king. And in the king's daughter, who is living without mother, the positive father complex is working. She stays in the heaven-spirit world playing with the golden ball, which can be seen as the state of inflation. She is disconnected from the earth-mother-feminine principle, which is important for a woman to find her genuine feminine identity. This demanded principle approaches her through the frog, a bewitched prince. Psychologically it means that a man is under the power of the negative mother complex. The disgusting, ugly frog is a symbol for the shadow, the earthly animal instincts of the princess. Only with his help she can find her golden ball again, which has fallen into the deep well. Their talk about the rewards to him for his help shows us very well the opposites. The frog wants the feminine value such as relation, earthly eros, but the princess offers the masculine value such as heavenly logos. After the frog brought her the lost ball, i.e. she regained her libido, she completely forgot her promise. Like this the content, which is becoming conscious, here the shadow, is easy to fall back into the unconscious and to be repressed. The frog cannot be with the princess without the help of the king, a father figure, a firm protector of the collective oder. At first unwillingly the princess obeys Logos of her father. But her authentic instinctual urge grows stronger and it causes that her ego is released from the power of her father complex. At just this moment the frog turns into a prince, i.e. he is liberated from the mother complex. The marriage of princess and frog-prince symbolize the unification of the opposites: heaven becomes earthly and earth becomes heavenly. Three iron bands, wrapped around the heart of Heinrich, a young king's servant, are snapped, while he brings the prince and princess back to his kingdom. The heart, the place of earth-mother-feminine consciousness, is now liberated. This principle, which disappeared into the unconscious, emerged into the collective consciousness and the wholeness is recovered. The Self is now leading the collective consciousness, which includes not only the principle of Logos but also Eros.

비 직선적 정(+) 저항온도계수 특성을 갖은 PTC thermistor눈 전이온도(큐리점) 부근에서 온도변화에 대하여 극히 큰 저항 값의 변화를 나타내는 산화물계반도체 저항기(또는 발열체)로써, 일반적으로 반도체의 온도-저항 특성과 같이 상온영역에서 온도의 상승과 함께 부성저항 특성을 나타내어 감소하다가, 온도가 점점 증가하여 큐리점 부근에 도달하면 저항이 급격히 증가하는 독특한 특성을 갖는다.

A new simple technique for 2-terminal negative resistance cireait analysis and synthesis is developed, by using the equivalent e.m.f. defined as a function of input lotage or current variation. The technique is applied to design 2-terminal junction transistor negative resistance circuits based on the parameter control method. Modeling circuits for SCR, GTO-SCR and SSS are also derived from the proposed transistor negative resistance circuits, and the merits of the modeling circuits are discussed.

HID 램프란 High Intensity Discharge Lamps의 약어로서 고압방전램프라 하고, 대규모 공간의 조명이 필요한 공공시설, 산업시설, 상업시설 이외에 스포츠 시설 등 폭넓은 용도에 대응하고 있다. HID 램프는 부성저항 특성으로 인하여 직접 전원에 접속하기 때문에 램프 전류가 흐르게 되면 급격히 전류가 증가하여 전류의 흐름이 매우 불안하게 된다. 따라서 이것을 안정시키기 위하여 전원과 램프사이에 전류 제한장치인 안정기(Ballast)로 램프 전류를 적절하게 제어할 필요가 있다. 본 고에서는 HID 램프에 관한 열화요인과 이에 대한 수명의 관계를 중심으로 논한다.

A new active resonator using defected ground structure with islands (DGSI) is proposed. The proposed resonator is composed of the conventional microstrip line with DGSI and negative resistance of active devices. The negative resistance part is realized by field effect transistor (FET) series feedback circuits. The characteristic of the proposed resonator with DGSI is improved by combining the negative resistance part with the parallel microstrip line structure with islands, where the electric field is formed the most strongly. The measured improvement of the proposed active resonator with DGSI are 4.55dB and 0.32dB in S21 and S22, respectively, at the resonant frequency whorl it is compared to the existing passive resonator having DGSI only.

This paper studies the instability between homopolar generator and constant power load with negative impedance characteristics, provides the design method of homopolar generator system which overcomes the instability. In case of magnitude and phase of impedance of source and load mismatch, control instability of source can occur. For the safety of phase of load impedance, the gain of P, I controller with sufficient phase margin is applied through analysis on the simulation model of generator system, and the gain limit of load impedance is ensured by limitation of the gain margin of generator system. The stability of power system can be increased by considering and analyzing the impedance of source and load.

This study treats the improvement of the dielectric strength of polymer by eliminating the air in it and dissolving electronegative gases. As experimental material, unsaturated polyester resin was used and the specimen was made by dissolving NS12T. SFS16T abd CCIS12TFS12T gases which have strong electron affinity. And also the electrical properties (tree growth and breakdown characteristics) of them were tested and discussed. The results are as follows. When the specimen dissolved with electronegative gas compared with one with air` 1) The tree breakdown voltage of the former is higher than that of the latter. 2) The tree growth of the former is slower than that of the latter. 3) The temperature dependence of the former is smaller than that of the latter. 4) The breakdown voltage of the specimen dissolved with electronegative gas is much higher than that dissolved with air.

For satisfying a recommended value of the quality factor which is one of the important elements in a filter design, a new design method of smoothing filter using an internal parameter of a homopolar generator is proposed. The method increases the efficiency and minimizes the size of the smoothing filter by removing the damping resistor. By considering the resonant frequency as well as the quality factor, the new method can improve the stability of the system which has high boosting converters with negative resistance characteristics.

In this paper, the electrical conduction phenomena of oriented polypropylene film were studied. Especially, as for the range of negative characteristics, it is observed that as increasing ambient temperature, the characteristics are shifted gradually towards the low intensity side of applied field with the decreasing width of the range as well as the fact that the currant oscillation takes place at the both transition points of the characteristics and that the point at the place the dielectric breakdown, occurs. Finally, it is also suggestive that the oscillation characteristics observed on the negative resistance range of the biaxially oriented specimen show the possibility to utilize it as active element materials.
