As an initial step to understand the transitions in Korean bronze technology the present study has examined metallurgical microstructures of 8 artifacts excavated from the Silla Wang-Gyong site in Kyongju. Important trends have been found in alloy compositions and also in manufacturing processes. In the design of alloys, the Sn content was apparently changing toward the peritectic point, 22 mass %, of the Cu-Sn phase diagram while the Pb addition was intentionally avoided. This trend in composition was found accompanied by the introduction, subsequent to casting, of such special thermo-mechanical treatments as quenching and forging in artifact manufacture. In addition, the Sn content in alloys containing a significant amount of As was relatively low and no evidence of forging was observed in them. The use of quenching and forging and the rejection of Pb and As from alloys are all necessary requirements if the brittle nature of high Sn alloys is to be overcome in bronze working. This paper will show that the Wang-Gyong era corresponds to that of innovations leading to the technical climax in Korean bronze tradition, which has been maintained up to the present. 본 연구에서는 경주의 신라왕경 유적지에서 출토된 청동유물 8점의 금속학적 미세조 직을 분석하여 이들의 제작에 적용된 청동기 기술의 변천과정을 추적하는 작업이 수행 되었다. 그 결과 합금의 조성 면에서는 주석함량이 22%를 지향하여 변화되고 있다는 사실과 의도적으로 납을 제외시킨 흔적이 명백하게 드러났다. 제작기법 면에서는 주조 를 근간으로 하되 단순히 주조로만 이루어진 경우와, 주조와 단조 또는 주조와 담금질 을 병행한 경우, 그리고 주조와 단조와 담금질을 모두 병행한 경우가 관찰되었다. 한편 비소를 함유하는 유물에서는 주석함량이 비교적 낮게 나타났으며 두드림 작업이 생략되 고 있었다. 담금질처리가 수행된 점이나 합금원소에서 납을 제외시킨 점 그리고 비소가 함유된 유물에 두드림이 생략된 점은 모두 당대의 장인들이 합금의 조성과 제작기법 간 의 상관관계를 이미 완벽하게 파악하고 있었음을 보여준다. 이러한 처리는 모두 주석함 량이 높은 청동기에서 소재의 취성을 낮추기 위하여 필수불가결한 것으로 이를 인식하 여 실천할 때에 비로소 청동기 기술체계는 완숙한 단계에 도달한 것으로 볼 수 있다. 본고에서는 왕경 출토 청동기에서 확인되는 다양한 수준의 제작기술을 제시함으로써 이 시기가 우리나라의 청동기 기술수준이 정점에 이르게 되는 변화의 시기였음을 보이고자 한다.

In the social and educational aspect of college is a sensitive project to emotions of the surrounding cities with the formation and development of city. Accordingly the topography and scenery of college which effects on a city and a community are interpreted in this study. This study treats of the landscape interpretation of a building site for college and the connection with the building in interpreting the landscape. The first research chiefly treats of the position interpretation of a structure. The second research interprets scenery of the existing building and the planned building by applying GIS to the area of research. This study aims to emphasize the importance of city scenery by explaining geographical, topographical characteristic of college buildings and the effect of college buildings on city scenery.

미집행 도시계획시설의 실태와 개선방안에 관한 고찰

Since defined as urban plan, Korean urban facilities are being placed on the status of non-execution caused by a number of factors. Particularly 73 cities occupy more than 70% of non-execution facilities, and followed the infringement of property right - generally accepted as a non-solved critical problem - whose possess above land owner. Hereby I suggest to improve non-execution facilities to cure our whole urban facilities, thus searching the reality of non-execution facilities and try to solve the solution thereby. As a concern arrangements, I suggest the solution to reduce and solve the non-execution facilities under the gradual and positive countermeasure as following by ; First, Korean non-execution facilities are on the critical situation, caused by financial insuffiency, but most of this followed by the lots of matters. Second, after analyzing the execution and non-execution facilities, most of the limited facilities are being executed and non-execution facilities might be long-termed tendency. Third, on the searching of the tendency of fundamental and time delayed execution facilities as the base of population scale, it could be figure out the typification under the control of non-execution facilities, and hereby suggest the lists which of characters. According to the analyzing contents on above mentioned, our non-execution facilities come to the point of crisis and urgently need to prepare turning point followed by the various direction of our current society to overcome.

Recently, laser technology has advanced to a point where accurate short-and long-lange measurements are possible to even relatively non-reflective object. This accuracy is achievable with a laser that meets the Federral Food and Drug Administration (FDA) eye safty requirments and is classified as eye-safe to Class 1 limits. This is a stand-alone instrument that has computing, editing and storage capabilities. Fore more complex computations, such as for volum or acreage determination, it has a serial connector which provides an interface with hand-held field computers or PCs. The most common use for this instrument on enginnering projects has been for load and trail pre-constrution surveys. Its portability, quick and easy operation, and record storage capacity make it well suited for this application.

This paper deals with real time building of rout and vertical alignment information system for the efficient and scientific management using GSIS. First, we redesigned rout and vertical alignment for obtain basic data using road projector(road design main software). Using by these acquired result, we made a database on road plan and vertical alignment drawing as a basic information being used to construction of road complex information system. The main objectives in this study are the rational maintenance road planing for drawings, its database and the systematization of rout information management through the fast updating, mending, supplement. Result of this study enables us to manage rout information effectively and scientific and we can expect to play an important role of results in the practical use for the management of the road alignment information.

Signal data which received at GPS observation stations located at Jangheung, Yeoriggwang. Suncheon in Jeollanamdo province and GPS satellite signal data which acquired in a triangulation point around the study area at the same time were implemented for data processing. In this study, signal data were set up for reference with a iteration in order for every GPS observation stations and then every points were analyzed and adjusted with geodetic network. This paper presents a evaluation of accuracy followed by each factor based on statistical results after quantitative analysis of the relative error of every decisive coordinate. In a conclusion, a surveying method using the data received at a GPS observation station could be improved by deducing the optimum baseline distance between GPS observation stations for minimizing reference variance and RMSE.

The development of electronic technology brings the advent of elctronic totalstation which measures, stores and records automatically angles, distances and 3d coordinates. Electronic totalstation is the surveying equipment and system 2000 is the supporting program that enables totalstation to get 3d terrain information, construction of the database and automatic drafting of the cartographic map. In this study, we aims at studying the system which can produce automatically the digital cartographic map by using totalstation and system 2000. For this study, cartographic maps of a region are produced by totalstation and system 2000, and then builded digital cartographic map on the autocad 2000 environment and also we analysed two digital cartographic maps. As a results of this study, it is found that digital cartographic map by totalstation and system 2000 are much more accurate and efficient than cartographic map by electronic plan table surveying, as well as this digital map may contribute to build the GSIS coverage map using Arc/Info or Arcview GIS program.
