Production of limestone for cement in Kangwon and Chungbuk areas reaches over 80 million tonnes per year. However, many regulatory activities for preservation of the environment against potential hazardous impacts from the open pit mining make it difficult for the industry. With recent improvement of the mining methods and working conditions, the regulations related to the quarrying of limestone may need to be revised. Methods for reducing environmental hazards are proposed in this paper, with some suggestions concerning the revision of related regulations. This study is expected to serve as a practical solution for the cement industry in balance of preservation and development.

This study aims at defining the concept of a cyber-geospace and proposing how to establish a cyber-geospace fir the entire country in detail. The study defined the cyber-geospace as 'the dynamic second territory of Korea not only to manage the land systematicality and deal with administrative services for the people in aspect of public sector, but also to contain economic activities of corporations and the citizen's everyday lives in aspect of private sector, in a 3D virtual reality made by digitizing various facilities and buildings as well as the entire toterritory including ground, underground and even sea'. In order to establish such a cyber-geospace, the project should be pursued on the national level fir around ten-year period.

본 연구는 아동의 탐색활동에 관한 연구에 지침이 되고 자극을 주고자, 또한 실제 지도에 있어 시사점을 발견하고자 이 분야에 관한 주요연구문헌을 고찰하였다. 그리하여 탐색활동을 놀이와 호기심과 비교하여 그 정의를 내리고 탐색활동의 기능과 특징, 그리고 이 활동에 영향을 주는 제 요인을 살펴보았다. 그 결과 아동의 탐색활동에 관한 연구자간의 의견차이를 보이는 것이나 연구공백이 있는 것이 여러부분이 됨이 드러났다. 즉 놀이와 탐색활동과의 구별, 탐색활동과 호기심과의 관계, 탐색활동의 동기, 상황에 따른 탐색활동의 유형변화, 탐색활동을 유발시키는 자극물의 특성-특히 공간적 특성, 탐색활동과 아동의 년령, 성별, 인지적 발달단계와의 관계, 그리고 탐색활동에 있어서의 개인차 등에 관해 더 많은 연구가 요구됨을 알 수 있었다. 특히, 아동의 탐색활동과 지적발달 또는 사회성 발달과의 관계나 아동의 발달과정에 따른 훈련이나 교육을 동한 탐색활동의 증진방안 등은 시사성 있는 중요한 연구테마로 보여진다. 또한 이 탐색활동에 관한 연구에서도 실험실에서 이루어진 연구가 자연적인 상황에 얼마나 일반화 될 수 있는지, 한 번의 관찰이나 실험이 계속적인 의미를 지닐 수 있는지에 대해 연구자들이 더욱 신중해야 할 필요성이 있음이 드러났다. 물론, 한 가지 이론이나 연구로서 탐색활동의 전부를 설명할 수는 없다. 유아교육자들이나 아동학자들은 아동이 그 자신의 환경에 적응하고, 사회적 유능성을 함양시키고, 진정한 의미에서의 지능발달에 중요한 것으로 드러난 이 아동의 탐색활동에 관해 더욱 관심을 가지고 여러 가지 이론과 연구를 빌어 연구나 실제 지도에 필요한 아이디어를 삼아야 할 것이다.

The propagation of blast vibration and the damping characteristics depend on both the mechanical properties of rock mass and weight charge. In this study, the characteristics of propagation and damping were analyzed by FLAC. The construction site was the second Kwang-ju circulating road. Taguchi method which is one of experimental design methods was used for determination of input data and parameter levels. The results showed that rock density was the most dominant of variables being concerned in this study, which affect the propagation of blast vibration.

The purpose of this study is to assist librarians in developing a biblographic tool for the bibliotherapy. Bibliotherapy is a form of psychotherapy in which carefully selected reading materials are used to assist a subject in solving personal problems or for other therapeutic purposes. However, bibliotherapy has rarely been either studied or practiced in Korea. For a bibliographic tool which is called 'situational bibliography', a client situation has to be classified by the factors of biological place and personal relations, type of stress or symptoms. This study, in this regard, is examined related recent researches in the field of psychology or psychoanalysis. Main conclusions made in this study are summarized as follows : The most important factors to classify a client situation in a bibliographic tool are sex, age, home background, personal relations and mental health issues.

A desing technique of 8 ports variable wave impedance generator (8P-VWIG) is described. The design technique employs not only a numerical algorithm to find the structure with arbitrary characteristic impedance, but also a numerical solution to analyze the uniform elementrognentic fields established inside the generator. The 8P-VWIG so obtained is shown to have good performance with the VSWR of less than 1.4 at any frequency of interest below which higher order mode begin to propagate. The measured first resonant frequency is 152.1 MHz. The 8P-VWIG is designed based on the concept of an expanded multi-transmission line(8 channel). It is especially useful for the electronmagnetic interference(EMI) and electronmagnetic susceptibility(EMS) testing since it maximizes usable test crosssectional area, and its is easy change the polarization, vertical or horizontal, of field.

In Part II, the temperature and smoke particle distributions of the extraction system, which yielded the best smoke removal performance among the three smoke control systems in Part I, for extraction flowrates of 0.6∼2.4 ㎥/s and two fire sizes of 200 ㎾ and 2 ㎿ were presented. The same numerical method was utilized to the same computational domain and configurations as Part I. It was shown that the extraction flowrate affects the smoke control performance significantly, and that a similar trend in improving the smoke removal performance with the increasing extraction flowrate between the two fire sizes. An extraction flowrate of 2.4 ㎥/s or higher was required for the temperature in the escape route less than $^{\circ}C$ for the given situations.

무한 사이버 공간인 인터넷의 발달과 함께 인터넷의 사용이 크게 늘어 거의 대부분이 인터넷을 이용하고 있다. 이러한 인터넷에서의 정보와 지식은 누구나가 어떠한 환경에서도 사용가능해야 한다. 장애인, 노인, 어린이, 약시 등을 고려한 웹 개발이 절실하다. 국내에서는 2008년 4월 11일 "장애인차별금지 및 권리구제 등에 관한 법률" 동법시행령(제14조)에 웹 접근성 의무화 조항 마련을 마련하여 복지 분야 뿐 아니라 인터넷에서도 장애인에 대한 평등을 강화하였다. 매년 웹 접근성 실태조사를 하고 있는 중앙행정기관의 웹 접근성 평균 점수는 2005년 72.3점, 2006년 81.8점, 2007년 88.2점, 2008년 90.6점이고, 광역지자체는 2005년 71.6점, 2006년 81.8점, 2007년 86.8점, 91.6점으로 해마다 향상되고 있는 것으로 나타났다(한국정보화진흥원 웹접근성연구소, 2009). 이와 비교해 볼 때, 민간기업의 웹사이트는 웹 접근성 준수율이 많이 낮으므로 본 연구에서는 한국 미국 일본 50대 기업의 웹 접근성 및 사용성에 대해 나라별, 기업별로 실증 평가 분석하여 문제점을 도출하고 개선안을 제시하여 민간기업의 웹 접근성, 사용성 수준을 향상시키는데 다소라도 기여하고자 하며 향후 IPTV, 휴대폰 등 다양한 웹 접근성 연구 분야에 대해 제시했다.

In order to meet the needs of the liturgical reform implemented by the Second Vatican Council, existing churches have been reordered and guidlines drawn for new buildings. With this reordering, perhaps the most perplexing issues facing priest and architect alike are the question of reservation and placement of the tabernacle. While in several documents including the documents of the Second Vatican Council, the church has made statement concerning this problem, not much has been stated definitely, And there are many different and. ambiguous things in the interpretation of liturgists and Episcopal Conferences. I examined and compared the issues which has been raised this while based on the Vatican Documents. The findings may be summarised as follows : (1) As the history of church architecture has seen great variety and innovation in solving the needs of the day, the church gives certain guidelines, but also allow great flexibility. (2) To achive good result, the priests and architects should work together in a language the other will understand. So theological interpretations on church architecture may be very useful. (3) The seperate eucharistic chapel which is near the santuary will be recommended as a location which accounts for both the communal and individual aspects of eucaristic adoration.

This study is to clarify the actual condition of the plan of high schools in the rural area. Recently, many high schools are remodeling the buildings and facilities based on departmental system. This study, through analyzing on 5 remodeling cases of high school in gyeongnam area. This article discuses about the basic characteristics of the plan composition and the education program of 5 high schools. This study is showing the variation before and after remodeling and space organization types. The results of this study are summarized as follows; We studied 5 high schools in 2012~2013 of them, which located in the rural area. We studied the location of department classrooms, teachers' labs and home bases of them. 1) Most of them take horizontal zoning system in the department classrooms. 2) The number of teachers' labs were increased in most of floors. On the other hand, most of Labs' area were decreased. Every department classroom zone has one teachers' lab. 3) Sample schools took much more spaces of home-base and media-space than before.
