In our study, the noise levels of the schools, the hospitals and the apartment complexes located near the main street in Masan city were computed by the computer simulation method. The sourse of noise were mainly traffic noise. The noise level chart was attained and compared with the values which was investigated in 1988. The noise values of hospitals, schools and apartment complexes were generally increased by 0 ~3 dB over those of 1988. The noise volues of twenty nine schools, seven hospitals, twenty two apartments and twenty three apartment complexes were higher than the international allowance(55dB) for city. But the noise levels of eighteen schools(62%), tow hospitals(29%), nine apartments(41%) and five apartment complexes(22%) were low than our national allowance(65dB) for city. The noise problems of three hospitals, six cohools, thirteen apartments, and nine apartment complexes were very critical. We have suggested possible improvement methods for the noise problems of the traffic.

이슬람교의 기독론 : 꼬란의 예수 이해를 중심으로

전재옥 이화여자대학교 한국문화연구원 1993 韓國文化硏究院 論叢 Vol.63 No.1

This thesis is to explore what Muslims believe about Jesus Christ based on the Quran. The reason why it is worthwhile and important to do such a study is that there is a decisive difference between Jesus of the Gospels in the New Testament and the Quran. There are quite a number of references to Jesus in the Quran. It attempts, thus, to find out all the possible references regarding Jesus in the Quran. The motive of studying about this theme, "Christology of Islam: Understanding Jesus in the Quran" has been as follows: The Korean Muslim community has been formed since 1956 in Korea and it is gradually growing and adjusting to the Korean culture. And simultaneously, the Korean church has started to have awareness of the Islamic world and its strength. However, there has been very little study done on Islam from a perspective of theology and missiology by Koreans in Korean language although there has been a growing traffic between the Muslim countries and Korea, between Muslims and Korean Christians from 1980s. Muslim awareness by Korean Christians is a reflection of international trend. The Islamic world is much on the world new with conflicts and apprehensions: in 1967, there has been Arab and Israel war. In 1978 there has been the revolution by Komeini-fundamentalism in Iran. In 1990 there was the gulf-war by Iraq. And most the Middle-East Muslim countries have oil power. In Afghanistan, there has been Mujahid resistance movement against the Soviet Union. 「The Satanic Verse」 by Salman Rusidi was a great shock news. Still many other Islamic peoples and nations are in a great conflict and threat in the West. It has been known to readers of histories and listeners of the world new that Islam and Christianity has been having a continuous conflict. At such time, it is necessary to have a wholesome approach to understand what Islam is essentially. Therefore, I have chosen this theme, Jesus in the Quran, as I think there is a fundamental difference between Islam and Christianity in understanding Christology. After introductory note in the first chapter, it deals with the designations of Jesus in the Quran in the second chapter. In order to find out where the sources of the names and title of Jesus come from, I tires explore possible sources from the Syrian church and the Apochripha (books which are not included in the Bible). It points out that the Quran did not have access o the written Scriptures (the Bible) to be directly quoted as there was no Arabic Bible available to Muhammad, the prophet of Islam. Then, it tires to give meanings of the titles and comes to clarify that although the titles and names are same or similar compared to the titles in the New Testament, yet, meanings are different. For example, the name, Jesus (called as Isa) in the Quran does not have soteriological meaning as it is in the Gospels (e.g.Mt.1:21) In the third chapter, it attempts to study on the annunciation to Mary, the mother of Jesus and the birth of Jesus. In the Quran, the message to Mary for the coming birth of Jesus as virgin birth is greatly emphasized and in lengthy description. The Quran is very concerned about the nobility of Mary and her purity. She is the only woman in the Quran who has a very high place among all women with her name, Mary, mentioned. However, the similar story of virgin birth of Jesus does not mean as same in the Gospels because Jesus is only a blessed child and prophet to be. He is no more than that. There is no soteriological meaning in this story as it is in the case of the name, Jesus in the Quran. In the fourth chapter, the ministry of Jesus has been explored. He is a prophet of some 40 prophets mentioned in the Quran although he is in a high rank with Adam, Noah, Moses, David, and Muhammad. He is respected and spoken highly by Muhammad, the prophet of Islam. He performs miracles and carries out teaching ministry among his disciples who followed him. Some references in the 5th chapter of the Quran, called the chapter of the table, indicate that he fed his followers with food from heaven. However, the meaning of the miracle performed by Jesus in the Quran is not the same as in the Gospels where Jesus claims to be the bread of the world nor with meaning of the sacrament which had started by the last supper of Jesus with his disciples. In the fifth chapter, the climax of Jesus story in the Quran, the crucifixion, is discussed in some length. Here, the Quran denies the death of Jesus on the cross. It is radically different from the story of the crucifixion in the Gospels. Many Muslim scholars discuss this with slightly different interpretations. However, they al have one issue in common: that is Jesus did not die on the Cross. Here the Christology of Islam is completely off the point as the Quran denies the redemptive nature of Jesus death. In Islam, fundamentally, there is no redemption. Hence, the meaning of sin is not the same as it is in the Gospels. Islam is basically a religion of self-effort for recognition before God. God accepts those who follow the way of Islam, the submission to the law of God and punishes those who do not do well. In the sixth chapter, the relationship of Jesus to God has been touched. Since Jesus is only a man and a prophet, he is not divine. His divinity, recognized in the title of the son of God, is vehemently repudiated in the Quran. The thesis points out that there is a complete misunderstanding in the Quran regarding the meaning of the son of God. The Quran violently criticizes that God cannot have a son because the sonship is understood in relation of God to Mary, the mother of Jesus. Therefore, the concept of the God of the trinity is denied in the Quran. Finally as a way of closing I have tried to encourage encounter between Muslims and Christians in spite of vital difference in Christological issue. Korean Christians need to have open attitude to understand Muslims as their neighbors and in order to do so, there is need to explore Islam in theological, cultural and missiological sphere. To understand where we are with our perceptions and misperceptions about Islam is a beginning toward encounter between Muslims and Christians in Korean context.

김채옥,김재욱 漢陽大學校 基礎科學硏究所 1993 基礎科學論文集 Vol.12 No.-

고온 초전도체 ??에서 Y대신 Ho를 치환시킨 시료를 제작하여 수송 임계전류밀도를 77K 온도에서 측정하였으며, 적외선투과율과 Raman스펙트럼 측정을 상온에서 실시하였다. 특히 Roman스펙트럼 특정은 100mW의 레이저출력에서 수직으로 편광한 경우와 수평으로 편광한 경우를 관찰하였다. 치환량의 변화에 따른 수송 임계전류밀도 값은 110~217A/㎠범위에 있었고 자기장이 증가됨에 따라 감소됨을 알 수 있었다. 적외선 투과율과 Roman스펙트럼으로부터 얻은 장이 증가됨에 따라 감소됨을 알 수 있었다. 적외선 투과율과 Roman스펙트럼 측정으로부터 얻은 Cu(1)-O(4) stretching mode는 초전도체의 결정구조를 좌우하며 산소의 영향에 강한 영향을 받는다. 또한 이것은 치환양이 증가됨에 따라 감소하는 경향을 보였다. Roman스펙트럼에서 수직 편광한 경우와 수평 편광한 경우 모두 asymmetric한 형태를 이루었다. 특히 수평편광의 경우는 BaCuO₂phase의 강도가 증가했다. High Tc superconductor ?? in which Y is replaced by Ho were prepared by solid state reaction. The measurement of the transport critical current density was determined at 77K. Infrared transmittance and Raman spectrum measurements were carried out at room temperature. The Raman spectrum measurements observed in vertical and parallel polarization at 100mW laser power. As substitution content changed. the value of transport critical current densities were in the range of 110∼217A/㎠. As the magnetic field increased, transport critical current densities were decreased. Cu(1)-O(4) stretching mode are assigned to provide a better understanding of the crystal structure and the role of oxygen defects in superconductor. Cu(1)-O(4) stretching mode were decreased with increased quantity of Ho concentration. Raman spectrum of vertical and parallel polarization were obtained as a form of typically asymmetric shape. Raman spectrum for the parallel polarization at 100mW was increased in intensity of BaCuO₂phase.

고온 초전도체 Y₁Ba₂Cu₃O??에서 Y를 Sm으로 치환시켰을 때의 수송 임계 전류밀도와 저항의 측정은 각각 77K와 80-160K범위의 온도에서 조사되었다. 그리고 X-선 회절 분석 및 적외선 투과율 측정은 실온에서 수행되었으며, 시료들은 고상 반응법에 의해서 제조되었다. 한편 치환양이 증가함에 따라서 정상상태에서의 저항값은 증가하는 경향을 보였고, 93K 근처에서 초전도 전이온도 Tc를 갖고 있으며, 치환양에 따라 거의 변화지 않았다. 적외선 투과율 측정결과 날카로운 peak들은 472.78~618.53㎝-1범위에 있었다. 이것은 특이할 정도로의 low-lying plasmalike edge와 낮은 에너지의 전자적인 여기가 존재함을 나타내는 것이다. 수송임계 전류밀도는 43.3~123.9A/㎠ 범위에 있었다. 전이온도 Tc에 상자성 불순물의 영향이 거의 없는 것으로 보아 123phase에서 Y가 고온 초전도성에 주된 역할을 하지 않음을 알 수 있었다. The measurements of the transport critical current density and resistivity of high Tc superconductor Y₁Ba₂Cu₃O?? were made at 77K and in the range of 80~160K. X-ray pellet diffraction and IR transmittance measurements were carried out at room tempemature. The samples in which Y is replaced by Sm were prepared by solid state reaction. As substitution content increased, the normal state resistivity was increased and the superconducting transition temperature Tc near 93K did not change significantly with the substitution content. From the infrared transmittance measurements many sharp peaks were observed in the range of 472.78~618.53㎝?. It indicates that unusual low-lying plasmalike edge and low energy electronic excitation exist. The values of transport critical current densities were in the range of 43.3~123.9A/㎠. From the observation of no significant change in Tc with mangetic rare earth impurities, it could be concluded that Y plays no crucial role in the high Tc superconduction mechanisms at the 123 phase.

흙댐 비탈傾斜度의 決定에 관한 硏究

嚴采永,玉致南 동아대학교 공과대학 부설 한국자원개발연구소 1980 硏究報告 Vol.4 No.2

Civil engineers have been applying the stability analysis to calculate the gradient of slope of earth dams so far. Nowaday the stability analysis is carried out by means of the digital computer. But this analysis is a complicated trial and error method for presupposed sections of dams and requires for highly skilled expert engineers to repeat tedious and expensive operations of a large size computer. In this paper, a new convenient and rational method is proposed instead of the complicated conventional analysis technique. The new method is based on the Fellenis method. All the conditions to calculate the gradient of slope are composed of the basic theoretical formulars and the empirical ones. The results are given from the computer calculated datas as the Determination Graphs for the Gradient of Slope of Earth Dams by using the Angle of Internal Friction and Cohesion. The proposed method has the following features ; 1. In case of using the Determination Graphs, the gradient of slope of earth dams are determined only by means of the statics property of soil instead of the conventional trial and error method. 2. When a dam is built more than 25.0M approximately in height, it is economical to use soil with greater angle of internal friction. 3. The safety factor of a dam is independent on the variation of the unit weight of soil. 4. The safety factor versus gradient of slope graphs show the linear trend of change.

Liquid phase epitaxy(LPE)법에 의해 InGaAsP quantum well(QW)구조를 성장하여 특성을 photoluminescence(PL)와 double crystal rocking curve(DCRC)를 이용하여 조사하였다. PL 측정결과, 상온 PL의 경우 well특성의 피크 에너지는 0.97eV이 FWHM은 80.41meV이며, 저온PL결과 well특성의 피크 에너지는 1.025eV이고 FWHM은 33meV이었다. 여기광의 세기를 증가시킴에 따라 PL 세기가 비교적 선형적으로 급준한 증가를 보이고 있어 well발광 특성임을 관찰할 수 있었다. DCRC결과, 격자부정합도가 0.32이고 한 쌍의 주기는 600Å이며 전형적인 Quantum Well특성의 위성피크를 관찰할 수 있다. In this work, We have grown the InGaAsP/InP quantum well by liquid phase epitaxy(LPE) and its some physical properties have been studied by photoluminescence(PL) and double crystal x-ray rocking curve(DCRC). In low temperature PL, the characteristic emission peak of well is observed at 1.025eV with a full-with-half-maximum of 33meV. As we increase the excitation intensities the emission intensities are drastically increased. From the DCRC analysis, we know that lattice mismatch between epitaxial layer and substrate is very low with a value of 0.32.

핀층의 두께변화에 따른 NiO/NiFe/Cu/NiFe Spin-Valve Sandwiches의 자기저항 특성

김채옥,김재욱 漢陽大學校 自然科學硏究所 1997 自然科學論文集 Vol.16 No.-

NiO 반강자성 박막을 이용한 spin-valve sandwiches 박막을 제작하여 NiO 반강자성층에 인접되어 있는 핀층의 두께변화에 따른 스핀밸브 박막의 구조와 자기저항 특성을 조사하였다. 핀층의 두께가 증가함에 따라 NiFe(111)과 NiO(111)의 XRD피이크의 강도가 커짐을 알 수 있었다. NiO기저층과 인접한 NiFe 자성층이 강한 교환이방성 결합을 함으로써 보자력이 작은 표면 NiFe 자성층은 7∼20Oe 범위에서 자화반전이 유도되어 저자장에서 민감한 자기저항 변화를 나타냈다. NiO/NiFe/Cu/NiFe 박막은 핀층의 두께변화에 따라 3.3∼3.5%의 자기저항비와 2%/Oe 이상의 큰 자장감응도를 보였다. Structural, magnetic and magnetoresistive properties in spin-valve sandwiches with various thickness of pinned layer in contact with the antiferromagnetic NiO film were investigated. The intensities of NiFe(111) and NiO(111) XRD peak were increased with increasing pinned layer thickness. The NiFe layer in contact with the NiO film was pinned by strongly exchange-biased coupling and the free NiFe layer at the film surface induced a sharp change in the magnetoresistance ratio in the range of 3.3∼3.5% and a field sensitivity above 2%/Oe with various thickness of pinned layer.
