High speed probe for measurement of sin91e flux quantum circuits is comprised of coaxial cables and microstrip lines in order to carry high speed signals without loss. For the impedance matching between coaxial cable and microstrip line, we have determined the dimension of the microstrip line with 50${\Omega}$ impedance by simulation and then have investigated the effect of line width and cross-sectional shape of signal line, dielectric material, thickness of soldering lead at the coaxial-to-microstrip transition Point, and the an91c between dielectric material and end part of the signal line on the characteristics of signal transmission of the microstrip line. From the simulation, we have found that these all parameter's had influenced on the characteristic of signal transmission on the microstrip line and should be reflected in fabricating high speed probe, We have also determined the dimension of coplanar waveguide to fabricate testing sample for performance test of high speed probe.

Generally, wind or solar power system is operated as a stand-alone power system, the efficiency of which could be higher by designing wind-solar combined system considering average wind speed and solar radiation of the desert region, Mongolia. This system is designed to generate electricity for power users and pumps the ground water for irrigation using deep well pump. The ground water can be used for farming or forestation where there is no or little irrigation system. In connection with this study, a renewable energy park, Green Eco Energy Park, was developed at about 50km east of Ulaanbaatar. 3 sets of 10kW wind power generator and 70 kW of solar power module were installed there. The electricity generated from the system is used to on-site office building and deep well pump for ground water pumping. A 10kW stand-alone solar pumping system, which has no rechargeable battery system, is installed to pump the ground water with the amount of generated power. The ground water is stored in 3 artificial ponds and then it is used for raising nursery tree and farming. The purpose of this study is to provide a possible energy solution to desert regions where there is no or little power system. The system also supply power to ground water pump, and the water can be used for farming and forestation, which will also be a solution of preventing desertification or spreading of desert area.

국내도입 원격제어 근접조사장치인 Ralstron(Shimatsu, Japan) 의 코발트-60선원을 이리디움 192 선원으로 대체하고자 선원을 설계하고, 선원주위의 선량분포를 유도하였다. 이리디움 선원의 물리적크기는 직경1.5mm, 높이 1.5mm 로 370MBq(loci)를 목표로 설계하였으며, 외경은 3mm 이고, 크기는 13m이며, 캡슐의 재질은 SUS316L 이다. 선원 선원자체흡수와 스테인리스 스틸 캡슐에 의한 선량감쇠는 61.2%로 나타났으며, 단위방사능당 감마상수는 4.69R$cm^2$/mCi-hr였다. 조직선량은 공기중흡수선량 변환과 조직산란보정을 통해 구하였으며, 조직흡수선량변환계수는 이리디움의 에너지스펙트럼을 이용하여 공기에 대한 조직의 질량에너지흡수계수비 ($\mu$$_{en}$ )$^{tissue}$ air= 1.112 를 얻었다. 고안 선원에 대한 선량분포는 선원을 2,338개의 선원으로 분할하고, 각 분할선원에서 주위에 도달되는 선량을 이산적으로 누적 평가하여 임상에서 사용할 수 있도록 선량도표를 제공하였다. We designed high dose rate Ir-192 source which was prepared for substitute the Co-60 source in Ralstron unit (Simatsu, Japan) which is supplied for cervical cancer treatment. The source dimension is 1.5 mm in a diameter and 1.5mm thickness of cylinder and encapsulated with 3 mm diameter of stainless steel(SUS316L) to substituted for the Co-60 source size. The Ir-192 source was prepared the dose model for tissue dose computation through the experimental determination of apparent activity and applied the empirical tissue correction factors extended to 20cm distance. The tissue dose model was applied the 4.69 R/cm-mCi-hr gamma constant and the ratio of energy absorption coefficient of water to that of air showed 1.112 include filteration of the self-absorptions. In this experiments, we prepared the dose computation software to clinical usefulness.

The Naked and the Dead에 나타난 Humanism

曺雲錫,金大明 慶北大學校 1985 論文集 Vol.39 No.-

Norman Mailer (1923∼ ) is generally called a war novelist just like James Jones, Irwin Shaw, Herman Wouk and so on. He is sometimes named a Jewish writer similar to Bernard Malamud, Saul Bellow, J.D. Salinger. But it is necessary to notice Ihab Hassan's comment as follows: All Jewish writers, of course, do not concern themselves exclusively with the "Jewish experience." Some, like Mailer, Bellow, or Salinger, accept no restriction on their material; others, like Malamud, writing mainly about Jews, move always into a far broader nexus of life, Here it might be said that the center of Mailer's literary world is the dramatization of human conditions in World War Ⅱ. It also might be said that Mailer's Humanism is the consistent center of his literary world in The Naked and the Dead (1948), as is shown by the characterization of General Cummings, Sergent Croft and Lieutenant Hearn. The various symbolic levels of the novel are dramatized in the conflict between three central characters: General Cummings, a symbol of 'Faustian Fascist'; Sergent Croft, an incarnation of 'Satanic Individualist'; and Lieutenant Hearn, an emblem of 'Liberalistic Humanist.' Sergent Croft is General Cummings' emotional twin and they are of a piece, as is expressed by Philip H. Bufithis; and Lieutenant Hearn is the modern liberal humanist, as is expressed by Howard M. Harper Jr. Therefore, it can be defined that The Naked and the Dead dramatizes the conflict between satanic fascists and a liberalistic humanist; in other words, the conflict between 'Fascism' and 'Humanism'. Mailer's Humanism is also shown by the creative technique such as 'Time Machine' and 'Chorus Section' devices. To give dramatic form to his characterization, Mailer dispenses throughout his narrative ten 'Time Machine' sequences, or flashbacks, in which he records the personal history of his main characters and thereby shows us how they have come to be what they are. Therefore, it might be said that 'Time Machine' gives us an open window through which we can look into the main characters' past. 'Chorus Section' device plays an important part in expressing Mailer's Humanism as well as the 'Time Machine' device. With the aim of giving dramatic form to his characterization, Mailer dispenses throughout his humanistic description five 'Chorus Section' sequences, in which he records the inner feeling of private soldiers and thereby shows us what they are feeling about what they are. In brief, it might be said that 'Chorus Section' represents the emotional sounding board of private soldiers, as is expressed by Thomas F. Van Laan. Finally, it can be stated that Mailer is a humanist fighting against satanic fascism named a mechanism of World War Ⅱ through the characterization of Cummings, Croft, Hearn, and common soldiers in The Naked and the Dead. The writer uses both 'Time Machine' and 'Chorus Section' devices in order to dramatize his own humanistic struggle. Here lies Mailer's greatness.
