강원,경북지역 낙엽송 지위지수 적합성 평가에 관한 연구
이대성 ( Dae Sung Lee ),이의섭 ( Eui Sub Lee ),최종현 ( Jong Hyun Choi ),서영완 ( Yeong Wan Seo ),최정기 ( Jung Kee Choi1 ) 한국임학회 2014 산림과학 공동학술대회 논문집 Vol.2014 No.-
본 연구는 강원 및 경북지역의 낙엽송 지위지수의 적합도를 평가하기 위해 실시되었다. 연구자료는 강원 및 경북지역의 45개 낙엽송 인공림 표준지 조사로부터 우세목 1본을 선발하여 수간석 해를 통해 분석되었다. 산림청에서 개발된 지위지수표에 의거하여 본 연구대상지의 지위지수를 산정한 결과, 지위지수가 18 이하로 낮은 지역은 8곳(18%)이었으며, 지위지수가 20 이상으로 우수한 지역이 37곳(82%)으로서 대부분 지역에서 지위지수가 우세하였다. 지위지수곡선의 적합도를 평가하기위해 수간석해목의 과거에서 현재까지의 수고생장에 따른 지위지수의 변화를 도시한 결과, 초기 임령 때 지위지수와 차이가 없는 곳은 단지 8지역(18%)이었으며, 지위지수가 2∼4 m 차이가 발생한 지역이 19곳(42%), 6 m 이상 발생한 지역이 18곳(40%)으로 나타났다. This study was performed to evaluate the compatibility of site index for Larix kaempferi in Gangwon and Kyeongbuk regions. The data were collected and analyzed from stem alalysis of one dominant tree at each of 45 permanent plots installed in the regions. The result of site index estimation following the site index table developed by Korean Forest Service (KFS) showed that 8 plots (18%) were less than site index 18 and 37 plot (82%) greater than site index 20. Height growth changes of stemmed trees until present were illustrated in a graphic form to evaluate the compatibility of site index curve. The result showed that only 8 plots (18%) did not show any change of site index as trees age, 19 plots (42%) fluctuated in 2∼4m and 18 plots (40%) over 6m.

화성 성역 물자 조달방법(華城 城役 物資 調達方法)에 관한 연구
최종현(Choi Jong-Hyun) 대한국토·도시계획학회 2009 국토계획 Vol.44 No.2
King Jeong-cho decided to move the town and villages of Soowon-bu in the process of moving the royal tomb of his father in 1789. King changed the name of Soowon into Hwaseong to be constructed as a new castle where many people and government officials would settle down. Numerous kinds of goods and much things should be supplied to build the castle from all regions of the nation. Various kinds of stone and brick were quarried or baked at near mountains and some places to the construction site. Many kinds of wood were cut at the various different places according to the uses and conveyed to the construction site. The supplying areas of some goods varied according to the kind of goods and most of the goods were moved to small port near to Hwaseong by ship. Unloaded goods from ships at the port were carried to construction site by some vehicles like cart and wagon.

The purpose of this paper will be tried out how the man-made culture IS influenced and how much our culture has been changed in the contexts of our basic philosophy, that is, the faith of mountain which is related with mountain and human beings during our historical period from Korea in the reign of TanGun to Yi Dynasty. It is analyzed to examine the function and role of mountain and to classify the faiths of mountain based on achieves and landscape paintings, old maps including the wall paintings of ancient tombs in the field of visual art. The mountain worship is a kind of belief to protect a nation, a community, or even a man with relying on the spiritual mountain which is the living site to come down the god. There are classified the god of mountain into the direction and territory limiting the space, the spacial existence in the reign of king as a sacred precinct facing south and north, the guardian mountain to protect the nation and to preserve the Royal house, the outer god to keep the peaceful living as the protecting deity of the religion, the management of all lives in fields and mountains, the guardian god to protect a community and the ancient god to control the house.

관광커뮤니케이션을 활용한 산업유산 관광지의 가치제고 효과 분석 : 마포 문화 비축기지의 사례를 중심으로

This study was intended to confirm the effect of these souvenirs by directly producing and distributing them as a means of tourism communication that could convey the value and meaning of Mapo culture tank. In order to achieve this goal, communication, survey and interview were conducted on 20 October 2018 for CAFE TANK 6 visitors in the Mapo culture tank community center. A total of 33 questionnaires were retrieved and all 33 were used as data for analysis. The results of the empirical analysis show that three factors, flexibility, meaningful delivery power and utility, have positive effects on recycling participation will. In other words, the value and meaning of reproduction were proven to have been delivered, and based on supporting interviews with visitors and officials, we were able to identify the experience of associativity and meaning. This has been demonstrated that renewable souvenirs, the means of tourism communication used in this study, can serve to convey the value held by the target site. However, with the limitations of the study that the number of samples is 33 and sufficient samples for analysis are not available, it is difficult to generalize the results of this study and 8 of the 12 hypotheses have been rejected, indicating that souvenirs as communication tools used in this study have failed to function to enhance the value of the destination itself. Nevertheless, as a representative place for modern industrial heritage, the importance of Mapo culture tank that has been transformed from idle land to cultural space through urban renewal projects is meaningful in measuring its effectiveness by organizing and experimenting with means of communication that can effectively convey the value of regeneration.

In steel making production line, steel slabs are given a unique identification number. This identification number, Slab management number (SMN), gives information about the use of the slab. Identification of SMN has been done by humans for several years, but this is expensive and not accurate and it has been a heavy burden on the workers. Consequently, to improve efficiency, automatic recognition system is desirable. Generally, a recognition system consists of text localization, text extraction, character segmentation, and character recognition. For exact SMN identification, all the stage of the recognition system must be successful. In particular, the text localization is great important stage and difficult to process. However, because of many text-like patterns in a complex background and high fuzziness between the slab and background, directly extracting text region is difficult to process. If the slab region including SMN can be detected precisely, text localization algorithm will be able to be developed on the more simple method and the processing time of the overall recognition system will be reduced. This paper describes about the slab region localization using SIFT (Scale Invariant Feature Transform) features in the image. First, SIFT algorithm is applied the captured background and slab image, then features of two images are matched by Nearest Neighbor (NN) algorithm. However, correct matching rate can be low when two images are matched. Thus, to remove incorrect match between the features of two images, geometric locations of the matched two feature points are used. Finally, search rectangle method is performed in correct matching features, and then the top boundary and side boundaries of the slab region are determined. For this processes, we can reduce search region for extraction of SMN from the slab image. Most cases, to extract text region, search region is heuristically fixed [1][2]. However, the proposed algorithm is more analytic than other algorithms, because the search region is not fixed and the slab region is searched in the whole image. Experimental results show that the proposed algorithm has a good performance.
