Purpose : This study was to analyze the demand for emergency ambulance service and to characterize the factors associated with the demand. Method : The basis for the model was from the actual demand for public emergency ambulance and socioeconomic and geographic characteristics. Multiple regression analyses were done for the related characteristics of public ambulance service. Result : The model explained total demand with a high degree of accuracy : the coefficient of determination($R^2=0.96$). For the regression, the set of variables indicative of low socioeconomic status were all significant. It showed the inappropriate use of public ambulance system. Public ambulance demand increased in higher housing density, low income, male unemployment and female labor force. Conclusion : The demand for public ambulances appeared to be highly predictable, using a simple linear model employing socioeconomic variables, quality of service variables, and land use variables. Low-income families tended, to use the public ambulance system more often than higher income. Area having elderly people or children also made many calls. Estimated demand calls were stable and had a tendency to be similar incident types.

해안지역의 인위적 간섭은 토사의 생산 및 유출에 의해 지형적인 변동을 유발한다. 더욱이 해안변동을 안정화시키기 위한 구조물의 설치가 다른 지역의 지형을 변화시키는 요인이 되기도 한다. 그러나 대부분 해안지역에 대한 토사 유출자료는 구축되어 있지 않은 실정이다. 본 연구는 장기적인 해안변동 경향, 해안변동의 주요 인자인 토사유출의 정량적인 평가 방안, 그리고 이를 고려한 접속도로의 설계하중에 영향을 미치는 요소에 대해 적절한 방향을 제시하고자 한다.

This study aims to develop a potential evaluation method for urban spatial expansion using remote sensing (RS) and geographic information system (GIS). A multi-criteria evaluation method with several criteria and their weighting values was introduced to evaluate the score and quantification of the potential surface around the existing cities. The six criteria with one geographic factor, slope, and five accessibility factors, time distance from center of the city, national road, interchange of expressway, a big city, and station, were defined for the potential. RS techniques were applied for classification of the actual urban expansion maps between two periods, and GIS functions were used for score of accessibility criteria with a distance decay function from geographic, road and several point maps, which was developed in this study. The new methodology was applied to a test area, Suwon, between 1986 and 1996. In order to optimize the six weighting values, this study made new findings to search the optimal combination of the weighting values from new methodology, weighted scenario method for intensity order (WSM), combined with intensity order and AHP method, including a trial and error method for sensitivity analysis to make the intensity order. The optimal combination of the weighting values by the new method generated the optimal potential surface, considering spatial trend of urban expansion in the test area.

Wood-cultivated ginseng, including roots in its dried form, is produced in forest land without using artificial facilities such as light barriers. To identify suitable sites for the propagation of wood-cultivated ginseng, factor combination technique (FCT) and linear combination technique (LCT) were used with geographic information system and the results were superimposed onto an actual wood-cultivated ginseng plantation. The LCT more extensively searched for suitable sites of cultivation than that by the FCT; further, the LCT probed wide areas considering the predominance of precipitous mountains in Korea. In addition, the LCT showed the much higher degree of overlap with the actual cultivation sites; therefore, the LCT more comprehensively reflects the cultivator's intention for site selection. On the other hand, the inclusion of additional factors for the selection of suitable cultivation sites and experts' opinions may enhance the effectiveness and accuracy of the LCT for site application.

In the discipline of design science, the integration of cognitive, semantic, and affective elements is crucial in the conception and development of a product. Affective components in IT artefacts have attracted researchers' attention, but little attention has been given to Geographic Information Systems (GIS). This research was conducted to identify emotions in web-based GIS, and determine design influences on the emotions using Kansei engineering (KE). In the evaluation procedure, ten web-based GIS were used as specimens, and 20 Kansei words were used as emotional descriptors in the Kansei checklist. 50 participants were asked to rate their emotional responses towards the specimens on the Kansei checklist. Principal Component Analysis was used to discover the semantic structure of Kansei, in which dynamism and spaciousness were identified. Significant Kansei concepts were identified using Factor Analysis, in which dynamic & well-organized, refreshing, spacious, professional, and nautical-look were identified. Partial Least Square analysis has assisted the research in discovering the significant design influence to the Kansei. These findings provide designers and other stakeholders with valuable knowledge for strategizing future web-based GIS designs that incorporate user emotions.

도시와 농촌간의 균형 있는 발전을 유도하기 위해서 탄생된 도농통합시는 지역특성을 고려하지 않은 무분별한 개발양상으로 인해 지역적 불균형이 더욱 심화되고 있는 실정이다. 따라서, 본 연구는 경상북도의 도농통합시를 대상으로 지속가능한 공간계획을 수립하기 위한 선행연구로서 지역특성 및 유형화 분석을 수행하고자 하였다. 먼저, 지역특성을 규명하기 위해서 인구규모, 농업구조, 생활환경 등이 반영된 변수들을 중심으로 인자분석을 적용한 결과, 개발지향적 인자, 농업적 인자, 생활환경적 인자, 미작적 인자, 과수적 인자가 추출되었고, 지역유형은 과수농업중심형, 중 소규모 농업형, 과소 침체 농촌형, 도시화 진행형, 도시 농촌 혼재형, 동남부해안 공업형으로 군집화되었으며, 지역유형구분의 신뢰도를 통계적으로 검증하기 위해 판별분석을 적용한 결과, 제II, V, VI유형은 100%이고, 나머지 유형은 90%정도의 신뢰도를 가지는 것으로 나타났다.

Esophageal cancer is a mjaor health problems in many parts of the world. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between esophageal cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. The highest degree of spread was in Germi town and the least was in Ardabil city. There was a significant relationship between effective environmental factors and esophageal cancer in Ardabil province. The results indicated that environmental factors probably are influential in determining the incidence of esophageal cancer. Also, these results can be considered as a window to future comprehensive research on esophageal cancer and related risk factors.

본 연구에서는 부산광역시를 대상으로 한 도시계획분야에서의 GIS를 활용한 토지이용분석 방법을 제안했다. 본 연구에서 사용한 부산광역시의 도시계획정보시스템 데이터베이스는 2000년대 초반에 구축되어졌다. 건물데이터는 수치지도(1:1,000)를 이용하였으며, 건축물대장과 수치지적도로부터 건물용도 현황 및 용도지역 지정현황 등의 속성을 입력한 것을 사용했다. 그리고, 특화계수의 산출로 부산광역시의 토지이용특성을 명확히 했으며 용도지역별로 특화범위를 비교했다. 또한, 건물용도별 및 용도지역별 관찰도수와 기대도수를 오버레이분석으로 산출하여 비교 분석한 결과 용도지역에 의해 건축물의 용도가 유도되고 있음을 알았다.

This study was conducted to examine the geographic variation among provenances of Pinus densiflora in survival rate and height growth at four test plantations (Jungsun, Chungju, Naju, and Jeju). The plantations were parts of the eleven provenance trials of Pinus densiflora established by Korea Forest Research Institute in 1996. The survival rate and height growth were significantly different among test plantations at $p{\leq}0.01$. Latitude and longitude of test plantation were negatively correlated with survival rate and height growth. On the other hand, annual mean temperature, mean temperature (Nov.~Feb.), extremely low temperature (Dec.~Feb.), and annual mean growing days of test plantation were positively correlated with these two. The relationships between growth variables and geographic variables were analysed with canonical correlation analysis. A considerable amount of variation in survival rate and height growth was explained by latitude, annual mean growing days, extremely low temperature (Dec.~Feb.) and extremely high temperature (Nov.~Feb.) of provenances. It is estimated that up to 47.1% and 67.4% of the genetic variability in survival rate and height growth was attributable to the environmental variability of the provenances, respectively. The response surface curve of survival rate and height growth was plotted against latitude and longitude to examine growth performance of provenances for each test site. Generally, the local provenances showed better survival rate and height growth.
