Kim Choon Min, Chang Nam Kee and Chung Whan Ho: Decomposition rate of plant residue and the vertical distibution of mineral nutrients in the woodland soil. The relationship between decomposition rate of litter and the amount of mineral nutrients dispersed to the soil horizons were studied on the oak and pine forest stand. The results are as follows: 1. Decomposition rate of litter was highest in the F horizon of the oak stand, however in the pine stand it was highest in H horizon. 2. The correlation coefficients between decomposition rate and humus, organic carbon, moisture content, calcium, phosphorus, and nitrogen in the pine stand are; 0.90, 0.98, 0.76, 0.98, and 0.88, in oak stand; 0.97, 0.93, 0.92, 0.97, 0.74 and 0.73. 3. Factors which affect the decomposition rate of litter are humus, organic carbon, moisture content, calcium, phosphorus and nitrogen. 4. Among the variables, PH, moisture content and phosphorus under the oak and pine forest showed significant differences in each horizon. 5. C/N ratio of pine stands is higher than that of oak stands studied. 6. The vertical distribution of mineral nutrients is highly related with the amount of humus accumulated on top soil.

This study was concerned about characteristices of Urbanization in regions around metropolitan. It has the purpose to make clear the structure of Urbanization in the northern outskirt of Daegu, Chilgok myeon, chilgok country, after searching the procedure of urbanization(1966-1976) and the actual Condition of urbanization. 1) In examining closely the procedure of urbanization, the comparative method was used and tried to understand the urbanization phenomenon as a regional phenomenon, As this study was geographic research in Urbanization. 2) Materials were dependent on existing statisties and those that I myself collected in the field by field-work. 3) In order to analyze actual conditions and procedure of urbanization, the following two indexs were used: (1) Changes of population-changes of total population, increase and decrease of population of each Dong(village), and change of industrial population. (2) Increase of Urban fuctional element-increase of houses, of shops, of factories of traffics and a jump of land price. The result of the analysis by the above method and indexes could be summarized as follows: 1) For nine years from 1966 to 1975, the population went on an an increase of 51.5%. In other words 7,124 persons increased from 13,828 persons in 1966 to 20,952 persons in 1975. such a rapid population increase was affected by the suburban explosin of Daegu. The density of population increased 152.4 persons/㎢ from 295.7 persons/㎢ in 1966 to 448.1 persons/㎢ in 1975. As for industrial population, the rate of the rural industrial population(1966-1971) was 13.7% down from 84.4% to 70.7%. On the other hand, the rate of urban industrial population was 5.3% up from 19.3% to 24.6%. In changes of population, the differences of each village being great, it was possible to divide the whole area into the growing, the nongrowing and the declining region. 2) Of urbanizing functional element increase; House increase rate from 1966 to 1976 was 39.5% but the house shortage rate increased 24% for the same period. And so the great house shortage took place. As for shop increase, all shops(84 shops) are retail trades, related with Daegu city. With factories and houses increasing, in this area we can find out the seperated urbanization phenomenon. As of 1976 August, the total of 79 factories were built in chilgok myeon dependent on the zoning program of Daegu city urban design. These factories are closely related with the technical development of Daegu. Traffics a day were 3,230 cars and so increased 15.6% a year. As the roads in this area were the most convenient, when compared with those in other area from Daegu. The urbanization on this area is growing rapider than in other area. During 1966-1976 the land price jumped 400-8300%. In other words this means the growing rate of urbanization. The urbanization of Chilgok myeon will continue in the future and social problems caused by the urbanization should be taken consideration in the policy.

Selectivity estimation of queries in relational databases has been studied extensively. Although relational selectivity estimation problems are well studied in the database literature, spatial selectivity estimation problems are not well understood. In this paper we examine selectivity estimation in spatial databases. In particular, we focus on spatial range queries over two-dimensional rectangular data. We propose and implement an improved equi-area partition for selectivity estimation of spatial range queries. We present a detailed experimental study comparing the proposed techniques and the currently used equi-area and nonequi-area partition for selectivity estimation.

김환건 서경대학교 1995 論文集 Vol.23 No.2

반도체를 보호하기 위하여 사용하는 반도체 성형 재료로, 현재 주로 사용되고 있는 Epoxy Molding Compound(EMC)에 경화제로 사용되고 있는 phenol novolac의 특성과 성형 재료의 관계를 조사하기 위하여 phenol novolac resin의 분자량과 깊은 관련이 있는 수지의 연화점 변화에 따른 EMC의 물성 변화를 살펴보았다. 사용된 phenol novolac 수지의 연화점은 각각 83℃, 88℃, 99℃인 3종을 사용하였으며 연화점 변화에 따른 EMC의 물성 변화를 살펴보기 위하여 기계적 물성 특성으로 굽힘 강도와 굽힘 탄성율을, 열적 특성 변화를 관찰하기 위하여 열팽창 계수와 열전도도 그리고 유리 전이온도를 각각 측정하였다. 그리고 성형 특성과의 관계를 살펴보기 위하여 spiral flow를 측정하였고, 전기적 특성으로서 volume resistivity를 측정 비교하였다. 기계적 물성측면에서 보면 탄성율은 연화점이 88℃에서 최소값을 보였으며, 강도는 88℃에서 가장 높은 결과를 나타내었다. 열적특성부문에서 살펴보면 유리 전이온도 이하 영역의 열팽창 계수(a_1)와 유리 전이온도 이상 영역의 열팽창 계수(a_2) 모두 연화점 변화에 따라 큰 변화를 보여주지 못하였다. 또한 유리 전이온도는 연화점 증가에 따라 감소하는 경향을 나타내었으나, 열전도도는 연화점 변화에 따라 변화를 보여주지 못하였다. 성형 특성 측면에서는 관계를 살펴보면 연화점이 88℃인 수지의 경우 spiral flow 가 최대치를 보이며 연화점이 증가함에 따라 더 이상 증가하지 않았다. 이러한 물성으로부터 내부응력을 계산하여 성형물의 특성을 고찰하였다. The physical properties of epoxy molding compound(EMC) according to the change of softening point of phenol novolac resin as hardener have been investigated in order to study the relationship between the properties of phenol novolac resin, which is main hardener of EMC for semiconductor encapsulation, and EMC. The softening points of used phenol novolac resin are 83℃, 88℃, and 99℃, respectively. The flexural strength and flexural modulus as mechanical properties were measured, and thermal expansion coefficient, thermal conductivity and temperature of glass transition(Tg) as thermal properties, spiral flow as moldability, and volume resistivity as electrical properties have been investigated to see the change of physical properties of EMC. The minimum of flexural modulus of EMC was represented at 88℃, and the maximum of flexural strength was done at 88℃. The thermal expansion coefficients in the region below Tg(a_1) and above Tg(a_2) keep constant value according to the change of softening point. Tg decreases with the increase of softening point of phenol novolac resin, but thermal conductivity is not hardly changed with that. It can be found out that spiral flow of EMC does not increases any longer above 88℃. We have considered these system in respect of internal stress.

매체의 종류와 내용에 따른 인지적 특성연구 : 뇌파(Electroencephalogram;EEG) 분석을 중심으로

전환성 청주대학교사회과학연구소 2006 한국사회과학연구 Vol.28 No.1

본 연구의 목적은 미디어 인식론적 입장에서 매체별(TV, Radio, 신문, 모니터) 및 내용별 자극에 따른 뇌의 반응 특성에 어떠한 차이가 있는지를 알아보려는 것이다. 뇌 반응(Brain Activity Responses) 특성은 (주)락싸가 개발한 뇌파검사기(모델명: QEEG-LEX3208)를 사용, 대학생 34명(남: 17, 여: 17)을 대상으로 8개의 측정부위(좌우 전전두엽-FP1, FP2; 좌우 전두엽-F3, F4; 좌우 측두엽-T3, T4; 좌우 두정엽-P3, P4)에 전극을 부착하여 뇌파(EEG)를 측정하였다. 측정된 뇌파의 상대파워(relative band power)를 계산, 기준뇌파(빈 모니터 화면에 의한 뇌파)를 준거로 뇌 반응 특성을 비교 분석하였다. 최종 분석에는 매체의 경우 22(남: 11, 녀: 11)명, 내용의 경우 24명(남: 11, 여: 13)의 자료가 사용 되었다. 연구결과 실험에 사용된 모든 매체와 내용 자극에 대하여 모든 측정 부위에서 기준뇌파에 비해 자극뇌파의 상대 알파 값이 감소하는 알파파 억제(alpha blocking) 현상이 확인 되었다. 반면 이와는 반대로 매체별 및 내용별 실험 자극물에 대하여 측정 된 거의 모든 부위에서 상대 세타 값이 증가하는 새롭고 특이한 현상도 발견 되었다. 그 이유와 원인을 밝히기 위한 추가적인 분석과 연구가 필요하다. 신문은 전 전두엽을 활성화 시킨 반면 TV는 좌우 전 전두엽을 제외한 나머지 측정 부위를 활성화시키는 등 매체별 뇌 반응 차이가 발견되었다. 자극에 대한 뇌 반응 특성은 내용에 따라서도 달라진다. 선정적 내용과 코미디 내용은 모든 측정부위에서 베타 값이 증가한 반면 스포츠와 폭력적 내용은 좌우 전전두엽에서 감소하는 차이를 보였다. 좌 반구(FP1+F3+T3+P3)와 우 반구(FP2+F4+T4+P4)를 묶어 전체로 비교할 경우 반구별 편측성은 검증되지 않았으나 측정 부위별 좌 우뇌 차이는 부분적으로 검증 되었다. The purpose of this study is to examine differences of Brain-Acticity Responses to media and contents through EEG(Electroencephalography). For this, four experimental media stimuli (same news) of TV, Radio, Newspaper and Monitor(displayed only in characters) and four of erotic, sportic, comical and violent contents for TV(same media) were used. Brain waves were measured on 8 electrodes (FP1, FP2, F3, F4, T3, T4, P3, P4) according to the international 10-20 electrode system to 34 sampled students of Chongju University using QEEG-LEX3208 which developed by Laxtha Inc. Raw data were transformed with FFT(Fast Fourier Transforn) and analysed in relative band power. 22 sample data(male: 11, female: 11) for media and 24 sample data(male: 11, female: 13) for content were analysed. The results show that relative alpha powers decrease at all electrodes regardless of media or contents, which refer to confirm the existing of alpha blocking phenomena. One of the important and interesting results of this study is that relative theta power increase at almost electrodes (except for T3 & T4 incase of comedy) both in media and contents in contrast to alpha power. Further researches are needed for explaining the reasons and causes. It is also found that brain-activity responses are little bit different depend upon medium and content. TV activate frontal, temporal, and parietal lobe excluding prefrontal, while newspaper activate prefrontal lobe. In case of radio, relative theta power is increased but relative gamma power decreased at all electrodes compare to background brain waves.

國家와 宗敎의 分離

黃煥敎 건국대학교 1984 論文集 Vol.19 No.1

Article 19 in the Constitution of the Republic of Korea stipulated that 1) all people shall enjoy the freedom of religion. 2) A state religion shall not be recognized, adopts the principle of separation between politics and religion. Most modern Constitutions adopt the stipulations of the freedom of religion and the principle of separation between state and religions. The relations between state and religions in a country are grasped as a mutual contact in the form of struggle or cooperation between the secular power (state) and the spiritual power (religion). Historically the relations between the state and religions were the theocracy of the unity of state and religion. Bui the relations between the state and religions didn't progress very smoothly. As we saw it through the history, because the influence that the religions give to the socity has been great, so the slate should try to guarantee the freedom of religion actually. the relations between freedom of religion and separation of the state and religions are the relation of purpose and means. The freedom of religion is the essential aspect of rights of citizens. The separation between the state and religions is institutional guarantee for the freedom of religion. In view of his fact, this paper will attempt an analysis of the relations between the state and religions from the angle of history and law. The freedom of religion, generally speaking, is understood as containing the freedom of confessing faith, the freedom of performing religious Programs, and the freedom of religious association. As a grate religion is not recognized, the stats is not allowed to grant special protection or privilege to any particular religion and the state is also prohibited from managing or providing financial subsidies to religious programs. Although there is no express provision in our constitution, separation between the state and religion is interpreted that churches and religious organizations are prohibited from interfering in politics. It is also stipulated that the legislation of laws which restrict the freedom and rights of citizens is forbidden except in cases that they are needed for national security, public order and welfare, no essential aspect of the freedom or rights shall be violated. This is because the freedom of religion unlike other rights to be free, is based on human being's spiritual world and therefore, an excessive restriction imposed on the freedom of faith is liable to infringe upon man's dignity and value as a spiritual being. The relations of the sate and religions should be based on critical and constructive collaboration.
