New methodology to evaluate the complex odor phenomenon was investigated, as called SA-ASTM(Sensor Aided ASTM ) syringe method. Specially we studied on the standardization of non-odorous air which is very important procedure in measuring odorous gas including our SA-ASTM syringe method. We examined the odor sensor value of standard hydrogen sulfide gas and non-odorous air made with ambient and cylinder air. The decision coefficient between H2S concentration and odor sensor value showed 0.992, and correlation formula between olfactory odor degree(Y) and odor sensor value(X) was Y =0.0039log(X) -0.4129. Also, it appeared that it was not appropriate to use ambient air itself because the odor level of ambient air varies with time, site, and situation. Instead we concluded that it was very effective for making the non-odorous air to use the cylinder air with traps which are composed of water, vacant tube, silicagel, charcoal vessels. The analysis results of odor samples by SA-ASTM syringe method using non-odorous air of this study explained the odor threshold and odor intensity well, which is the basic characteristics of odor and necessary data to use the odor dispersion model.

김준배,백창선,김학진 한국화재소방학회 2001 한국화재소방학회논문지 Vol.15 No.1

소방호스의 밀착강도 시험방법을 개선하기 위하여 5개국(한국, 미국, 영국, 중국, 일본), 7개의 기술기준(KOFEIS, UL, NFPA, BS, 중국기술기준, JIS, 일본검정기술기준)을 비교 고찰하고, 국내에서 생산되는 소방호스를 무작위로 발췌하여 밀착강도시험을 실시하였다. 밀착강도시험 및 기술기준 비교 고찰을 통하여 밀착강도시험은 소방호스의 호칭별로 시험시효의 크기와 박리시험속도 및 판정기준을 세분화함으로서 소방호스의 밀착강도를 개선시킬 수 있다는 결론을 얻었다. In order to improve the adhesion test methods for fire hose, 7kinds of stands (KOFEIS, UL, FM, NFPA, BS, Chinese standard, JIS, JFEII standard) un 5 countries (Korea, USA, UL, China, Japan) were compared and adhesion tests were conducted by using the samples choosed randomly from the product produced in Korea. It was concluded that the sample size, the rate of seperation of a strip of the lining from the jaket and standard judgment should be more differed and divided in accordance with the fire hose number in adhesion test to get the high qualily of fire hose

This study has been conducted to prevent problems arising from the fact that private lands are among the road lots currently used as public roads and the compensation for this is not systematically made. Until now, the compensations for the fees for the private roads have not been made, and the property rights are preserved and the compensation for the fees are paid in the form of individual lawsuits only when a party infringed on property rights raises a complaint. As a result of extracting private roads through GIS, Chuncheon-si’s private roads accounted for 55,757 lots (55.7%), 4.2㎢ (21.5%), and 463.4 billion won (30.5%), respectively, out of 100,134 lots, 19.5㎢ in area, and 1.517 trillion won in economic value. There are seven types of private roads. 1) Cadastre inconsistency type, 2) specific road section type in public area, 3) road type in multi-family housing site, 4) accessing road type to existing village, 5) internal road type in existing village, 6) connecting road type in urban areas, and 7) accessing road type to new small housing development complex. It can contribute as basic data to identify the current status, identify the parcels to respond first, and prepare systematic compensation plans through the classification of types of private roads.

The purpose of this study is to analyze the spatial cluster characteristics of fire using long-term fire data. For this, fire data which were broke out in the last 40 years were converted into GIS data and spatial analysis was performed at Gangwon-do province's minimum administrative district level. In order to grasp the spatial distribution of the fire, Moran's I, Geary's Ci and Getis-Ord's Gi*, which are methods that analyze the local indicators of spatial association(LISA), were used. By integrating the characteristics of the spatial distribution of fire by integrating the results obtained from each analysis, the advantages of the individual analysis methods were reflected in the study results. As a result of the study, hotspot areas of fire in Gangwon-do was derived out. Among the hot spot areas, some areas, where the fire frequency is higher than the adjacent areas, have been identified. The results of this study can be used as information for predicting the fire hazard area and relocating of fire-fighting facilities in the study area.

This study conducts quantitative analysis with the use of GIS of characteristics of Buddhism relics spatial locations such as Buddhist temple sites. With the intention of analysis of the generally known Buddhist temple site locations from spatial side, following the Buddhism relics sites state, the present conditions of Buddhist temple sites was analyzed from the spatial point of view. The results of the present study are that, comparing with general location analysis, different characteristics of competitive strength which maintains Buddhist temple sites functioning until now are showing. In case of such cities as Chuncheon and Wonju, Buddhist temples exist in the areas of high locational competitiveness, and most of them were located in the areas which with relatively poor environment. On the other hand, comparing with Samchuk city case, the location environment of Buddhist temples there turned out to be excellent. Such results show that we can discover the special characteristics of Buddhism which holds the entire history for the space called the Korean Peninsula.

1910년대 지형도를 이용한 근대화 이후의 도시 변화 분석

In order to plunder the Korean Peninsula in earnest, ``Modern Age Korea Topographical Map`` of reduced 1:50,000 scale was manufactured within the period of 5 years from 1914 to 1918 through Japanese government-general of Joseson. This map includes all the data representing the life model of Korean Peninsula in the period of the End of Korean Empire, before the modern public construction works had started to seriously develop. This study analyzes the land use change after embedding the coordinates to the image of Modern Age Korea Topographical Map, which includes the scenery of 1910, and then overlaying it with the contemporary map in GIS environment. The results of presented research showed that before modern civil construction works started, the farmlands had lost their competitiveness because of difficult for development hilly areas and frequent floods, the river sites being abandoned and industrial structure change, and were developed into modern city area.

The map drawn on a scale of 1 to 50,000, modern Korea map drawn on a scale of 1 to 50,000 made by Japanese colonial era in 1910s, is the first topographical map using modern technical method. The map has been mainly used in human activities and geographic viewpoint, recently it is available on various field with recognizing high accuracy. It is especially expected that the map will provide us with lots of information on long-term change of topography in field of coastal area which is built on coastal structure. This study presents a method for analyzing before and after geographic change of coastal structure in independent drift sand system. The reference point to analyze long-term coastal geographic change was selected the map of 1910s.
