偏析型 2元系合金의 溶體化末期에 있어서 非平衡第2相의 固溶擧動에 대해서는 아직까지 理論的으로 정립되어 있지 않았다. 本 論文에서는 主로 dendrite element의 境界에 晶出된 非平衡第2相의 유효擴散距離로써 1次arm 間隔을 考慮한 擴散 model인 尹의 近似解에 의해 이들 擧動을 調査하였다. 이를 위해 天然가스등의 輸送材料로 囑望되는 高濃度 Al-8%Mg合金을 사용하였다. 實驗結果, 理論的인 尹의 近似解의 實驗値는 近似的으로 一致되었고, 특히 溶體化末期에서는 完全히 一致됨을 알 수 있다. 結局 從來의 Flemings의 解析値보다 더욱 實驗値에 近似하였다. The solution kinetics of nonequilibrium second phase of a segregated binary alloy in the later stages of solution treatment have not yet been made theoretically clear. This paper attempted mainly to investigate this behaviour by Yoon's approximate analysis given by a simple model based upon primary arm spacing as an effective diffusion distance of the second phase which has crystallized at the boundary of dendrite element. For this purpose, we used the high magnesium Al-8% Mg alloy which is expected to be used for transport of liguified natural gas. The theoretically calculated results are in the approximate agreement with that of experiments for complete dissolution time and solution kinetics (expecially at the later stages) of β-phase. The Yoon's approximate analysis was in better agreement with the present experimental results than the Flemings conventional analysis

The construction works with concrete has the potential problems of water tightness. The conventional treatments for water-tight concrete are not satisfactory in terms of strength and water tightness. This study was to investigate the effects and application of the asphalt-coated portland cement on water-proof of the concrete and its influences on the physical properties of the concrete. The asphalt-coated portland cement, which is hereafter referred to as ACPC, was made by coating ordinary portland cement with asphalt in the rate of weight ranging from 0.5 to 1.0 percent. In this process, Calcium Chloride and Sodium Silicate were tried as the hardening time accelerator for producing ACPC, and carbon black, talc and other materials were tested for their effectiveness as pore filler. The specimens were prepared and tested with the various amounts of additives as a variable factor to find the optimum material. The analysis was mainly focused at water tightness, physical properties of the concrete and working conditions. The major findings of this experiment are as follows ; 1) Water-proof Test ① The specimens of ACPC and ordinary portland cement(OPC) were tested under the pressures of 3 and 9 kilograms per square centimeter per 24hours respectively and compared. The OPC specimens showed considerable amount of leakaged water while the ACPC specimens were rated lower permeabilities of 89%/28days, 40%/56days and21%/84days under the abovementioned pressure conditions. The most successful composition for water-proof was identified as ACPC added with Calcium Chloride and carbon black. ② The ACPC demonstrated its superiority in absorption test. The absorption amount of OPC for l hour was greater than that of ACPC for 24hours. 2) Compressive Strength Test Four kinds of specimens of ACPC aging 7, 28, 56 and 84days were tested and compared for their respective results of OPC. The ACPC added with carbon black was lower than OPC in compressive strength in the case of curing ages of 7 and 28days but ACPC was superior to the OPC in the specimens aging 56 and 84days. The ACPC added with others except carbon black exposed their lower compressive strength in all circumstances compared with the OPC specimens. 3) Slump Test The slump of ACPC with various additives such as carbon black, talc or clay was 21.6 centimeter which was higher than the OPC of 18.4centimeter slump. This result concluded that ACPC was much favorable in workability in comparison with that of the OPC. The conclusions are summarized as follows; 1) The optimum mixture for water tightness and compressive strength of concrete was found at 0.5% of SACPC, Calcium Chloride and carbon black respectively at the rate of the weight of cement.

Kap Soo Yoon,Jin Pyo Hong,Chae Ok Kim,Ja Hyung Koo,양정엽,Young Deung Kim 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.3

Magnetic tunnel transistors (MTTs) based on AlOx tunnel barrier were formed to obtain more ecient spin-dependent transport of hot electrons. The insulating AlOx barriers were grown by a remote rf plasma oxidation method to enhance electrical and structural properties of the MTTs. Further emphasis in this work was placed on the improvement of Schottky barrier properties of Si collector with plasma and chemical pretreatment of Si-substrate. The highest magnetocurrent ratio and output current of the MTTs were experimentally observed to be about 6 % and 42 A at VEB of 0.5 V, respectively. Especially, a transfer ratio of about 10က2 was obtained by varying barrier heights of emitter and collector electrodes in our experiment.

Until now there have been much research for worship revival. Churches, however, still continuously need worship revival. As with the proposition, "Reformed Church should always reform", worship should always be in constant revival. Unlike the previous studies on this subject, this is an attempt for worship revival through a trinitarian worshiper. Although our worship is to the Triune God in the works of the Trinity, it has not been trinitarian in practice. Firstly, worshipers' lack of recognition and understanding of the Trinity might have caused this. But a more fundamental cause might be that the Western theologians have not fully grasped it both biblically and practically. Traditionally, in the 2000 years of the Christian history therehave been three major ideas about the Trinity: 1) Father centered, 2) Nature centered and 3) Three Persons centered, each of which has not rightly recognized the Triune God because of their non biblical elements, though partly biblical. It would be obvious that you cannot worship God as you should without knowing Him as you should. This thesis tries to propose "a holistic understanding" of the Triune God, which is based on one of the co-writers' PhD thesis. And we want to show that the worship revival that is acceptable and pleasing to God will take place when we become true "trinitarian worshipers". We hope that through this writings you come to recognize the transcendency of the Father and the immanency of the Son and the presency of the Holy Spirit; and that many will become the trinitarian worshipers who have intellect, mind and spiritualty harmoniously from recovering the imago trinitatis, once lost because of sin.

The Korean Church should help the elderly face their last stage of life with a positive attitude, to bear fruits of a meaningful life, and give glory to God. In order to achieve this goal, the church's education for the elderly, needs to be developed and revitalized to meet their needs. It is necessary to develop and vitalize the church education for seniors, so it will be suitable for their happiness both concretely and practically. This study examines the concept and present condition of the church's senior education program on the basis of existing researches by inquiring into literature, and designed plans for vitalizing the church's senior education through qualitative case studies. The plans for vitalizing church's education for the aged, suggested by this study are as follows. First, is the realization of a need for a mission and education for the elderly. Second, programs are needed to support communication between the elderly and their family. Third, support unofficial networks. Fourth, is the need for continuous self­developmental education to help prepare for death. Fifth, developing a volunteer program for seniors in the church, for good health management, and create a feeling of involvement. Sixth, the development of church educational programs regarding creating jobs for the senior citizens. Seventh, is the development of educational programs regarding spiritual information. Various elements such as the radical collapse of the traditional supporting system of the family, compared to the strengthening of the national welfare policy for the elderly, the lack of understanding of Korean society for the education of the elderly, and the rapid increase of the elderly are reviewed. It is predicted that the role and the function of the church's education for the elderly will be expanded more than before. Therefore, the Korean church must strive to vitalize the church's education for the elderly.
