This study examined disaster risk from climate change in urban open spaces. This study conducted an assessment depending on type of damage and type of open space, subcategorizing it into flood damage and wind damage, flat park and mountainous park, and classified the assessment items by type into natural factor, artificial factor, and social factor for the purpose of analysis. Our major findings from this study are as follows: To look at the standardized score for the disaster risk from flood damages in the case of a flat park, Asian Park was higher at 55.800 point than Seoul Forest at 51.775 point, and in the case of mountainous parks, Dogok Park was at 58.428 point and Baebongsan Park was at 58.374 point. To look at the standardized score for disaster risk from wind damage, in the case of a flat park, Asian Park was higher at 64.763 point than Seoul Forest at 61.054 point, and in the case of mountainous parks, Baebongsan Park was higher at 58.533 point than Dogok Park at 55.459 point. This study raised a question about the necessity for and value of this disaster risk assessment in open space from damages caused by climate change, established an assessment model for disaster risk from damages in open spaces only to attempt risk assessment. Disaster risk of urban green space was enhanced.

With the increase in occurrence frequency and severity of natural disasters due to climate changes arising from global warming, damage in the landscaping field is rising. This leads to legal disputes, and is increasing social and economic damage, too. Especially even though landscape trees which are highly affected by external environments, suffer lots of damage from natural disasters, there is no specific scope of disaster criteria and thus it brings plenty of problems of damage restoration and compensation. Therefore, this study aims to suggest that gives ways to improve related criteria for damage of landscape trees from natural disasters. For this objective, this study analyzed damage cases of landscape trees and precedents, and compared Korean and Japanese legal systems and criteria regarding natural disasters with each other. The analysis result showed that opinions of experts have a great deal of influence on judgment results, since there is no definite legal basis on damage from natural disasters in the landscaping field. This implies the need for a professional and objective appraisal process. According to the comparative analysis of Korean and Japanese legal systems and criteria regarding natural disasters, Korea lacked in laws and criteria on natural disasters of landscape plants in Korea, whereas there were concrete disaster assessment standards of landscape trees in Japan. For improving natural disaster-related systems and criteria in the landscaping field, therefore, this study presented 'Revision of related laws', 'Revision of appraisal and loss assessment criteria', 'Revision of standard specification of landscaping project', 'Compulsory insuring against disasters', 'Reasonable fulfillment of contract', and 'Compulsory cost estimation for disaster restoration', as improvement plans.

In this study, the general structure of the landscape architecture industry was considered through analysis of advertisements in the landscape architecture magazine, 'Environment & Landscape Architecture', and the transition process and factors of landscape facilities were analyzed. Based on this result, the direction of future landscape facilities and basic data were suggested. When analyzing the advertisements that have been published in 'Environment & Landscape Architecture' for 30 years, outdoor facilities were depicted at a frequency of 1,853 times and among them, rest facilities and convenience facilities were depicted 1,457 times and 378 times, respectively. The reason why outdoor facilities have a far higher advertisement frequency than other landscape facilities is they were highly influenced by the house construction-related government policy, which resulted from the expansion of the rest facility industry along with regional expansion to public design. Moreover, it was found that wood and steel were mainly used to make pergolas and benches, which are rest facilities, and polycarbonate, with high economic efficiency and durability, was used the most as a roofing material for pergolas. This study attempts to explore the tendency of landscape facilities and the changes in the detail of their types by analyzing the stream of landscape facilities diachronically, based on the advertisements published in a representative magazine of landscape architecture.

본 연구는 전산화단층촬영에서 간 질환의 자동 인식으로 질감특징분석(texture feature analysis. TFA) 알고리즘을 제안하고자 하였으며, 간세포암(Hepatocellular carcinoma. HCC)에 대한 컴퓨터보조진단(computer-aided diagnosis. CAD) 시스템을 설계하고, 제안하는 각 알고리즘의 성능을 평가하고자 하였다. HCC 영상에서 분석영역(40×40 픽셀)을 설정하고 각 부분영상에 통계적 특징을 이용한 6가지 TFA 파라메터(평균 밝기, 평균 대조도, 평탄도, 왜곡도, 균일도, 엔트로피)비교하여 간세포암 인식률(recognition rate)을 구하였다. 결과적으로 TFA는 간세포암 인식률을 나타내는 척도로 유의함을 알 수 있었으며 6가지 파라메터에서 균일도가 가장 인식률이 높았으며 평균 대조도, 평탄도, 왜곡도가 비교적 높았고 평균 밝기와 엔트로피는 상대적으로 낮은 인식률을 나타내었다. 이와 관련하여 높은 인식률을 보인 알고리즘(최대 97.14%, 최소 82.86%)을 간세포암 영상의 병변을 판별하여 임상의 조기 진단을 보조하여 치료를 시행한다면 진단의 효율성이 높아 질 것으로 판단되었으며, 향후 효율적이고 정량적인 분석을 추가함으로써 질병인식의 일반화에 대한 기준 연구가 필요 할 것으로 사료되었다. In this study, texture feature analysis (TFA) algorithm to automatic recognition of liver disease suggests by utilizing computed tomography (CT), by applying the algorithm computer-aided diagnosis (CAD) of hepatocellular carcinoma (HCC) design. Proposed the performance of each algorithm was to comparison and evaluation. In the HCC image, set up region of analysis (ROA, window size was 40×40 pixels) and by calculating the figures for TFA algorithm of the six parameters (average gray level, average contrast, measure of smoothness, skewness, measure of uniformity, entropy) HCC recognition rate were calculated. As a result, TFA was found to be significant as a measure of HCC recognition rate. Measure of uniformity was the most recognition. Average contrast, measure of smoothness, and skewness were relatively high, and average gray level, entropy showed a relatively low recognition rate of the parameters. In this regard, showed high recognition algorithms (a maximum of 97.14%, a minimum of 82.86%) use the determining HCC imaging lesions and assist early diagnosis of clinic. If this use to therapy, the diagnostic efficiency of clinical early diagnosis better than before. Later, after add the effective and quantitative analysis, criteria research for generalized of disease recognition is needed to be considered.

‘내동리 명물’을 통해 본 일제강점기 경성 시민의 경관 인식

김해경,유주은 서울역사편찬원 2014 서울과 역사 Vol.- No.87

In the 1920s that was the period of cultural governance ruled by Japan, diverse media were founded and media events were conducted to boost circulation. As one of those events, Dong-A Ilbo conducted a media event which readers chose the specialties of Naedong-ri by themselves, on June 1924. In this study, the types of the chosen specialties in 100 out of 186 dongs and towns, Seoul where Korean people lived. and landscape cognitions of Seoul citizens were analyzed, and the results are as follows. First, the types of the chosen specialties were divided into villages and places, architectural elements, infrastructures, biological elements and others. There were 14 villages and places, and an aggregation of other buildings that had certain areas and were different from existing ones, and markets and farms where sold or raised special items on a large scale, were chosen. As architectural elements, there were 54 modern buildings, traditional buildings and structure that accounted for the biggest proportion, and why there were 36 traditional buildings, is it was limited to residential areas of Korean people. As urban infrastructures, wells, bridges and caves were selected. In addition, natural environment which showed a beautiful scenery all the time, figures, animals and insects that aroused interest, and plants in changed circumstances were chosen as biological elements and others. Second, the articles written about the backgrounds of choosing the specialties of Naedong-ri were analyzed, and surrounding landscape cognitions of Seoul citizens are as follows. There were mixture of yearning for modern civilization and despair for the colonial era, pity for Joseon of the past and disconnected tradition and detailed interest in ordinary elements that they had seen for a long time. It is hard to interpret that these were universal landscape cognitions of Seoul citizens, since the readers who participated in choosing the specialties of Naedong-ri, belonged to the intellectual class at that time. However, this study has significance as an empirical research on the meaning of procedure in which citizens chose local specialties themselves, and landscape elements during the Japanese colonial rule. 일제강점기 문화통치기인 1920년대에는 다양한 매체가 창간되었고, 발행 부수 확보를 위해서 미디어 이벤트를 실시했다. 그중 『동아일보』가 1924년 6월 독자가 직접 참여하여 ‘내동리 명물’을 선정하는 미디어 이벤트를 실시했다. 경성 186개의 정동 중 조선인 거주지역 위주의 100개소를 한정하여 선정된 명물의 유형 및 경성시민의 경관 인식을 분석한 결과는 다음과 같다. 첫째, 선정된 명물은 마을 및 장소·건축요소·기반시설·생물요소 및 기타로 유형을 구분할 수 있다. 마을 및 장소는 14개소이며 일정 면적을 지닌 기존과 다른 건물군의 집합, 특정 품목을 대규모로 팔거나 식재한 시장과 밭이 선정되었다. 건축요소인 근대건물·전통건물·구조물은 54개소로 가장 많은 비중을 차지하며, 전통건물이 37개소인 것은 조선인 거주지역으로 한정한 필연적 결과이다. 도시의 인프라에 해당하는 기반시설에는 우물·다리·굴이 선정되었다. 생물요소 및 기타에는 변함없이 아름다운 풍광을 유지하는 자연환경, 흥미 위주의 인물·동물·곤충, 과거와 다른 처지에 놓인 식물이 선정되었다. 둘째, 내동리 명물의 선정 배경을 작성한 기사를 분석한 결과 경성시민의 주변 경관에 경관인식은 다음과 같다. 근대문물에 대한 동경과 식민지라는 시기에 대한 처지 비관의 혼재, 사라진 과거의 조선과 단절된 전통에 대한 연민, 오랜 시간 지켜본 일상적 요소에 대한 세밀한 관심을 볼 수 있다. 내동리 명물 선정에 참여한 독자는 당시의 지식층에 해당하기 때문에 경성시민의 보편적인 경관 인식으로 해석하기에는 무리가 있다. 그러나 시민이 직접 참여하여 지역 명물을 선정하는 과정적 절차에 대한 의미와 일제강점기 경관 요소에 대한 실증적 연구로써 의의가 있다.
