This study focuses on some evangelism models to reach secular people. John Wesley’s “ Order of Salvation" model, James Engel’s “ Count Down" model, Agnes Liu ’ S “ Triangle" model, George Hunter's “ Target" model, and Joseph Aldrich’s “ Relationship" model are reviewed. John Wesley’s “ Order of Salvation" model is effective in understanding how secular people become Christians. Further, it is also effective in conserving the new converts. Its small group dynamics can be contextualized in different cultures. James Engel’s “Count Down" model is effective in understanding how secular people become Christians in terms of spiritual maturity However, it overlooks the multi dimensions of how people become Christians. Agnes Riu’s “ Triangle" model is an effective way to understand the several dimensions of how secular people become Christians. It is better than James Engel’s model in this regard. However, it shows an extremely simplified conversion process. George Hunter’ s “ Target" model is an effective way to understand how secular people become Christians, also. It is an extended form of John Wesley’s “ Order of Salvation" model. It takes the c비tural gap into a serious consideration Joseph Aldrich’ s “ Life- Style Evangelism" is based on inter personal relationships. As the early church employed this model, so too modern evangelism needs to apply it to reach secular people effectively. Some evange1ism models are more effective than others according to different cultural contexts. So some models needs to be contextualized in different cultures to be effective. The Lord wants a greater harvest.

본 연구는 직접메탄을 연료전지(Direct Methanol Fuel Cell)에 적용가능한 양이온교환막 개발에 관한 것으로 poly(vinyl alcohol) (PVA)에 가교제로 poly(acrylic acid-co-maleic acid) (PAM)와 hydroquinonesulfonic acid (HQSA)를 이용하여 가교제의 함량을 변화시키면서 막을 제조하였다. 제조한 막은 가교제의 함량 변화에 따라 메탄을 투과도, 이온전도도를 측정하였으며 기본적인 이온교환막의 특성인 함수율, 이온교환용량 그리고 고정이온농도 등을 측정하였다. PAM 함량이 증가함에 따라 메탄을 투과도와 이온전도도 및 함수율이 조금 증가하는 추세를 보이다 9 wt%부터 감소하는 경향을 보였는데 이는 PAM의 친수성기보다는 가교효과의 영향이라 사료되며 HQSA 함량을 변화시켰을 때는 이온전도도, 함수율 그리고 이온교환용량이 전반적으로 증가하였는데 그 증가폭은 미비하였다.

The electrical and thermal conductivity of W-Cu composites were investigated as a function of the W-particle size and W-W contiguity. Powder mixtures were prepared by ball milling or mechanical alloying process, and then sintered at various temperatures. The electrical conductivity of sintered composite was increased with decreasing W grain size. Dependence of electrical conductivity on the W grain size was explained by the W-W contiguity concept. The thermal conductivity was increased with increasing the temperature up to but decreased at the temperature above Also, thermal conductivity value was influenced by the W particle size. Change of thermal conductivity in W-Cu composites was discussed based on the observed microstructural characteristics and theoretical considerations.

The study of church growth takes effective strategies of evangelism seriously, because of its theological foundation that ‘Church Growth is Faithfulness to God. ’ Church growth theorists believe that this growth of the church will be accomplished only through constant works of evangelism and proclamation. Such evangelistic endeavors will eventually produce the growth of the church In this study, therefore, the writer attempts to summarize a few important methods of evangelism which was dealt in the study of church growth. Moreover, based on constructive critiques from the holistic view of rnission, the writer attempts to present holistic strategies of evangelism, which leads to the concept of holistic church growth. The first strategy of evangelism developed by Church growth theorists is its emphasis on evangelism based on the concept of ‘people group.' The concept of people group has been firstly introduced by Donald McGavran and became the essential elements of church growth theory . Secondly, based on its new discovery of people groups, homogeneous unit principle became the most important strategy of evangelism in church growth theory. Thirdly, the theory of receptivity is examined and critiqued in its positive and negative contributions in the study of church growth. In spite of its significant contributions of discovering and utilizing strategies of evangelism, church growth theory is still open to valid criticism due to its too much emphasis on numerical growth. Therefore, based on new emphasis on holistic view of church growth, the writer attempts to employ Eddie Gibb’s dimensions of church growth and had adopted and developed these concepts for developing holi stic strategies of evangelism and church growth in this study. They are; 1) strategy of growing up of didacke, 2) strategy of growing together of koinonia, and 3) strategy of growing out of diaknoia. Based on these elements, the true and holi stic church growth will be accomplished.

기존의 연구에서 제안된 한반도내의 전도성 구조를 정량적으로 해석하기 위해 전도성 구조를 고려한 3차원 지자기 모델링을 수행하였다. 모델링 결과는 관측 유도 지시자를 잘 설명하며, 모델에서 설정된 임진강 벨트와 옥천대의 전도도 구조에 대한 가정이 유의미함을 보여주고 있다. 한반도의 서중부 관측점들(YIN, ICHN)은 임진강 벨트의 영향을 반영하는 것으로 보이며, 한반도 서남부의 관측점들(HNS, CHY, DZN, MWN)은 옥천대의 영향을 반영하는 것으로 보인다. 관측 유도 지시자로부터 해양효과를 제거한 차이 지시자를 계산하였는데, 한반도 서부의 관측점들은 주기 60분에서 관측 유도 지시자와 큰 차이를 보이지 않았고 특히 YIN, ICHN은 주기 10분부터 동일한 양상을 보여 주고 있는데 이러한 결과는 옥천대와 임진강 벨트가 심부까지 확장된 전도성 구조라는 가설을 지지한다.
