Accoustic impedances of subsurface layers are determined from the amplitudes of reflections from the layers. Densities of the layers can also be calculated from the accoustic impedances in case where velocities are known by velocity analysis of reflection data or any other method. The accoustic impedance is a good information for direct identification of the kind of some subsurface material like coal or oil.

Raw materials in steel industry decide on the productivity, quality and price competitiveness. Utilizing iron-containing by-products as raw materials for steel products can save the cost of cleaning up iron-containing by-products and solve environmental issues. Iron-containing by-products have a small particle size. If they are directly inserted in a steel making process, it cause a problem such as poor heat flow and scattering. To solve these problems and induce the additional reduction, study concern with iron ore-coal mixed briquette technique are conducted by many researchers. In this paper, method of making carbon composite briquette iron(CCBI) using iron-containing by-products was studied. The effect of composition of Fe-containing process wastes, reducing agent, flux and binder on formability of CCBI (carbon composite briquette iron) was measured. 철강 산업에서의 원재료는 생산성, 품질, 가격경쟁력에 결정적인 역할을 하고 있다. 철강제품의 원재료를 함철부산물로 활용한다면, 함철부산물을 처리하기 위한 비용 및 환경오염문제를 해결할 뿐만 아니라 가격경쟁력을 높일 수 있다. 함철부산물들은 대부분 작읍입도를 가지고 있어서, 제강공정 내에 직접 투입하게 되면 열 유동 및 원료 비산 등의 문제가 발생하게 된다. 이러한 문제점을 해결하고 추가적인 환원을 유도하기 위해 철원에 탄재를 혼합한 뒤 단괴를 성형하여 제강공정 내에 투입하는 방법이 연구되고 있다. 본 연구에서는 함철부산물에 탄재를 혼합하여 단괴를 성형하는 방법에 대해 연구하였다. 함철부산물, 탄재, 융제, 바인더에 따른 CCBI (carbon composite briquette iron)의 성형성 및 압축강도를 확인하였다.

In recent decades, Korean religious groups have increased their political influence and conflicts between different religions have become visible and intensified. In this context, we examined the levels and patterns of religious exclusiveness in both private and public domains and the reasons for their expression in South Korean society. We used both statistical analyses that used the 2008 KGSS dataset and in-depth interviews with 15 interviewees. After pointing out limitations of the religious index developed in the United States in the multi-religious South Korean religious context, we introduced a multidimensional index that consists of religious faith, religious act, and religious function and employed both conventional variables commonly used in religious studies and new variables that seem to capture multi-religious aspects of South Korea. Results of statistical analyses show that religious faith and act have significant effects on the tolerance toward a spouse of different religion. But religious function has no significant effect on this matter. Especially the level of faith in Buddhist doctrines and the frequency of attendance in religious meetings have significant effects. In the case of support for political candidates of different religion, only religious act has an significant effect while both religious faith and religious function have no effects. Especially, the frequency of prayers is the most significant variable. Also, in general, both Buddhists and Catholics are less exclusive than Protestants in matters of marital selection and political support. Results of in-depth interviews show that religious exclusiveness is the lowest in friendship, and in support for political candidates and interpersonal relationship at workplace in decreasing order. It is the highest in marital selection. As seen in statistical analyses, differences among religious groups are also observed in in-depth interviews. Protestants are the most religious exclusive toward people of different religious in both private and public domains, and both Buddhists and Catholics are not exclusive toward other religions. Protestants exhibit strong propensity to apply their Christian teachings, rituals and practices, and values to other people, workplace and political arenas, and this causes ill feeling and repulsion among Buddhists and Catholics toward Protestants.

This study was conducted to establish of landscape planning for landmark design as a part of publicity strategy for the activation of a regional festival. It was carried out landscape Planning to introduce a landmark of butterfly-shaped as an object of the Butterfly Festival which is opened at HamPyung in Chonnam province. Especially, it was planned to easily approachable to an annual event place and recognition on the festival content for a visitor from another district. Furthermore, we led the landmark is able to be effective publicity by an allowance of strong image which may cause one's interest as a planning of a symbolic figure(landmark) which is changed in stages by a change of visual point.

This study is to attempt in order to make the space as an identity and amenity and more intimacy of our cities by the preparation of Community Sign. This study aims to propose the direction of solve a problem, based on the analysis of the status on the sign of urban which is the need of sign facilities of urban is recently felt. The results clearly research of this study are as follows: ① Continuity allowance of furnish information and to avoid the disproportion of information. ② The necessity of research for a location and an establishment method of urban sign. ③ Quality support of Community Sign. ④ The introduction necessity of Community Sign can be communicate to everybody including the physically handicapped.
