The causes of noise generation according to the classification of indoor spaces are very diverse. Individual happiness is infringed by this noise. In this paper, We tried to visualize the spatial sound characteristics of public places using sound color to express them so that anyone can sympathize. The noise inside a conference room of a medical device company was measured for 100 minutes, and the frequency band was divided into three different types of existing sound pressure expression units. Because the size of the noise is expressed differently depending on the situation, There are cases where there is a difference of opinion between the measurer and the researcher. This noise measurement experiment was conducted, and the sound color was applied to classify it on a log scale considering auditory characteristics. As a result of comparing this with the result expression for different loudness expression units, A specific table in different units yielded almost similar results. In addition, the sound source section for 100 minutes was divided into three analysis sections, the analysis sections were different, and the size of the energy ratio for each analysis section was divided in the form of an envelope. The characteristics of the low-frequency region of the space have a high energy ratio, and the decrease in the energy ratio according to the increase in frequency is constant and regular. You can see that conversations are possible.

The objective of this study is to investigate the characteristics of the location and prospects of the bear shelves built by Asiatic black bears in the Jirisan National Park. Previous researchers have been analyzed bear shelves in terms of places for resting and eating, but we are going to analyze based on the prospect-and-refuge theory. Characteristics of the sites of bear shelves are measured through field survey and topographic analysis by using digital elevation model (DEM). The normalized difference vegetation index (NDVI) is used to evaluate the optimum location of bear shelves in terms of crown density. Man-made objects are identified by viewshed analysis based on geographical information system (GIS). Findings of this paper can be summarized as follows. First, most bear trees are located deep inside of the mountainous national park, slopes of 30~40 degrees, altitude of 400~1,200m, and relatively low vegetation density with NDVI value of 0.4~0.6 compared to the average NDVI of the park. Second, the average height of bear shelves is 12.44m, or 74% of the average height of bear trees. They are located at suitable places to observe nearby trails and other park facilities. Third, man-made objects within the 100m radius of bear trees include lodge, bear training center, beekeeping camp, and hiking trails. Thus we may temporarily conclude that one of the main criteria of the bear tree selection in the park has been to identify optimum places for the monitoring of human activities in their habitat.

The purpose of this study is to research and analyze the distribution of night illumination level at urban neighborhood parks and to show its characteristics. And this is used basic data ensuring safety and satisfying aesthetic and psychological desires of people who use urban neighborhood parks at night. To research and analyze the distribution of illumination level at urban neighborhood parks at night. To research and analyze the distribution of illumination level at urban neighborhood parks, I selected 8 urban neighborhood parks as the subject of research in this study, set the measuring standard of illumination level, and measured the illumination level by the measuring standard. The results of this study are as follows; 1. Currently, total average illumination level of urban neighborhood parks was lower than the minimum standard of illumination level I KS A 3011-1993. 2. Average illumination level of each place in urban neighborhood parks appeared variously from low level to high level. But this was lower than the minimum standard illumination level in KS A3011-1993 like total average illumination level. 3. The higher was total average illumination level of urban neighborhood parks, the more various was brightness of places. Although users' aesthetic and mental desire or behavioral aspect relate with safety cannot be found by only survey and analyses of illumination level, it is judged that first, illumination level of the standard of the lightness should be analyzed to find user's mental states and behaviors in external space at night. Therefore, it is considered that this study, which analyzed characteristics illumination level as basic data, has a significance. The study continuing for other illuminative environmental factors suitable in the place is required because the brightness of places may not be measured by only illumination level. And the proper illumination level in outdoor places should be showed in considering psychological and behavioral aspects of human as people may have their own sense of brightness.

최근에 미국, 영국, 일본에서 폭발물, 독성 화학물 등에 의한 테러가 공공장소에서 시도되고 있다. 위험물을 공공장소에서 두고 가는 방식은 탐지하기 어려운 방법 중에 하나로 인식되고 있다. 공공장소에는 곳곳에 카메라가 영상을 녹화하고 있지만, 그 영상을 사람이 일일이 모니터링 하는 것은 쉽지 않은 일이다. 최근에는 자동으로 영상을 분석하는 지능형 소프트웨어를 유기물 탐지에 이용하고 있다. Lin 등의 방식은 비교적 높은 유기물 탐지율을 보이고 있으나, 단기 배경 영상의 특성으로 유기물에 관련한 픽셀의 수가 시간이 지날수록 급격히 감소하는 경향이 있어 그 형상 정보를 얻기가 어렵다. 본 논문에서는 면적의 변화 특성을 분석함으로써 유기물의 형태를 성공적으로 추출하기 위한 새로운 기법을 제안한다. 제안한 방식에 대해 실험을 한 결과 선행 연구보다 형태 추출에서 우수한 성능을 보인다.

본 연구의 목적은 관광안내서 등 현대 도시사회에서 시민들의 여가와 관광활동의 정보매체가 되는 비학술문헌의 분석을 통하여 탐방선호장소들의 장소적 특성을 연구하려는 것이다. 연구범위와 방법은 서울 내의 유형별 탐방명소들을 대상으로 관광안내문헌에 나타나는 장소별 빈도와 내용분석을 통해 대표적 장소적 특성을 규명하려 하였다. 유형별 탐방명소는 '자연형 탐방명소', '역사형 탐방명소', '생활문화형 탐방명소'로 대별되었다. 유형별 대표장소는 빈도분석에 의해 각각 남산과 한강, 덕수궁과 경복궁, 이태원과 대학로로 선정하였다. 상기 문헌연구와 이를 보완하는 현장연구를 종합하여 전도시적 차원, 주변맥락의 차원, 장소적 차원의 세 단계에서 서울 탐방명소의 장소적 특성을 도출, 해석하였다. 각 유형간의 차이에도 불구하고 세 유형이 공유하는 지배적인 장소적 특성은 배경을 이루는 도시공간과의 가시적, 용도적 '대비성'과 주변지역과의 활동적, 의미적 '연계성', 그리고 단위 탐방명소 내부에서의 '가시성'과 '체험성'이라고 할 수 있다. 즉, 배후도시의 환경과는 가시적, 용도적으로 명료하게 대비되면서 주변지역들과는 연계 관광적 여건이 원활하고, 장소 내부에서는 가시적 독특함과 체험적 다양성이 갖추어질 때 탐방명소로서 효과가 강화될 수 있다고 파악되었다. 본 연구결과는 동시대 사람들이 느끼는 도시 탐방명소의 보편적 매력요인이자 장소적 특성으로 볼 수 있으며, 향후 이들 특성들을 강화하는 방향으로 탐방명소와 그 주변의 도시환경을 조성, 관리할 때 도시 전반의 정체성과 관광효과를 증진시킬 수 있을 것으로 기대된다.

Traffic accidents due to excessive speed frequently occur in places where traffic signal controllers are installed, places where sharp curves exist, or places where the traffic signal cycle does not match the current time. These traffic accidents cause economic loss due to the destruction of road facilities and structures, and cause a big problem of increasing the number of traffic accident deaths. When a traffic accident occurs, leaving a tire mark before or after a car crash, pre-collision speed of the car is calculated using the law of conservation of momentum or the skid mark formula. In the skip skid mark generated in ABS brake vehicles and the combshaped yaw mark generated by tire trace caused by lateral sliding, there is a difference of 30-40% in the reliability of the vehicle speed calculated by the smite mark. In this paper, we propose an algorithm that can improve the calculation reliability in vehicle speed by using skid marks in order to compensate for this problem. In addition, we present an intelligent speed calculation algorithm for traffic safety and a computer simulation in order to prevent traffic accidents by estimating the speed of a vehicle, using Skid marks, Yaw marks, and ABS brake characteristics and fuzzy rules.

In order to provide basic data for designing the outdoor exercise environment to promote the health of the citizens, this study has analyzed the status of citizens' use of outdoor exercise places that have been supplied extensively recently and the factors affecting the citizens' choice of the places. A survey was made on 20 spots in 12 places where outdoor exercise equipment is installed to identify the characteristics of use and the factors affecting the selection of the spots and for the 1,733 survey sheets collected finally SPSS program was used to analyze the multiple answers. Major results of this research are as follows: First, since light exercise equipment mostly for bodily exercises has been installed, it has brought practical effects for the physically weak people, aged people and the people who scarcely exercise, while decreasing the users' economic burdens. Second, the scales of important factors the users think in selecting their exercise spots were 'spaciousness (2,028 times)' > 'accessibility (1,751 times)' > 'fitness (1,583' > 'supportability (1,445)' > 'community centeredness (1,260).' Third, the ratios of important factors regarding the choice of environment of outdoor exercise were 'near to walk (16.1%)' > 'nice natural environment (12.3%)' > 'always free to exercise (9.7%)' > 'shortage of exercise equipment (7.4%)' > 'possible to accompany family/neighbors (6.7%)' > 'no economic burden (6.5%).

Advances in information and mobile technologies have changed the traditional firm ways of working very flexible, collaborative and innovative, resulting in the changes in work place structures and layouts. Despite the growing body of literature examining the novel ways of working, which is called smart work, there is little academic attentions paid to the spatial aspects of new work places, namely smart offices and smart work centers. This research explores the spatial changes of work places that improve business efficiency and collaboration among workers suitable for the novel ways of working. Conducting in-depth field surveys on selected cases, we analyzed the changes in spatial structure and operation policies of smart offices and smart work centers. From this survey, we observed that the new work places under study take various novel spatial forms and they have flexible operating policies such as flexible seating and flexible work hours. We also found that it would be difficult to change existing business practices and typical ways of performing tasks, without changing the bureaucratic spatial designs and layouts. Future studies are suggested to examine how spatial structures and layouts of offices have impacts on space utilization, collaboration, creativity, and job satisfaction.
