  • The predictive capacity of wastewater treatment facility in the industrial park was estimated by the traditional method and on-the-spot survey such as certification of wastewater report and the invoices of water supply and ground water supply. The ratios of a converted wastewater to supplied industrial water between traditional method and on-the-spot survey in the estimation methods were different. By using traditional method, the business type of clothes, accessary and fur production had 77.18 % of waste ratio of wastewater and $10.72m^3/day{\cdot}1000m^2$ unit mass of wastewater as the highest among 9 business types. With the respect to the on-the-spot survey, food manufacturing business type had 75 % of waste ratio of wastewater and $8.35m^3/day{\cdot}1000m^2$ unit mass of wastewater as the highest values. The amount of wastewater from on-the-spot survey method was 541 $m^3/day$ less than one from traditional method.

  • Geometric corrections are required to compensate skew effects, earth rotation effects and so on. Parameters for geometric modeling can be acquired from the metadata information. These parameters allow to locate on ground every pixel of acquired images. In this paper, we tested the precision of geometric modeling of linear pushbroom images, acquired by SPOT 3 and 5 using the satellite orbit information itself without additional external data. The result acquired from examination to recovery the geometry of image using 30 GCPs have about 650m RMSE in SPOT 3 and about 170m RMSE in SPOT 5.

  • 본 연구는 2011년 100ha 이상의 대형산불 피해지인 울진과 영덕지역을 대상으로 하였으며 산불피해강도를 평가하기 위해 현장조사와 고해상도 위성영상자료 분석을 병행하였다. 위성영상자료 분석 시 산불피해지역의 피해강도를 가장 적절하게 평가할 수 있는 영상분류기법들을 비교 분석하여 최적의 피해강도 평가방법을 선정하였다. 대형산불 피해지역의 최적의 피해강도 평가기법으로는 현장조사에서 획득한 트레이닝 지역의 정보를 이용한 최대우도법을 적용하였을 때 가장 좋은 평가결과를 보였다. 산불피해강도의 정확도 검증 결과, 평균 전체정확도는 88.38%와 Kappa coefficient는 0.8147로 나타났다. 분류정확도는 최대우도법, NDVI, 최소거리법 순으로 나타났다. 산불피해강도 현장조사 결과와 위성영상자료에서 추출한 피해강도의 상관관계는 울진산불 피해지에서 r = -0.544, 영덕산불 피해지는 r = -0.616으로 나타났다.

  • In this paper, we suggest and implement an internet survey system cooperating the randomized response technique(RRT). We compare it with the direct survey. RRT is an indirect survey method to get true information from the respondent who is conceived to have sensitive character without revealing his/her status. We implement our system(method) based a data-base system, so it common all kind of data obtained through internet surveys. This system also can be used in spot survey independently.

  • 본 연구는 부산, 대구, 광주, 대전 등 4개 대도시권역을 대상으로 대중교통서비스가 열악한 대중교통사각지역을 선정한 후 이들 지역간을 운행하는 새로운 급행대중교통수단 도입 시 기성 시가지내 통행자들과 수단선택 행태가 어떻게 다른지를 분석하기위해 SP 조사(stated preference survey)를 통한 수단선택 행태변화에 대해 네스티드 로짓모형을 구축하여 분석하였다. 연구결과 대중교통사각지대는 잠재 대중교통수요가 많아 기성시가지에 비해 자가용통행으로부터 새로운 대중교통수단으로 전환하는 통행전환 비율이 매우 높은 것으로 분석되었다. 이러한 연구결과는 향후 대도시권 외곽 순환도로 혹은 외곽지역에서 도심지역으로 연결되는 간선도로를 활용한 새로운 급행 대중교통체계 도입시 수요변화 평가와 외곽지역의 대중교통 잠재수요 분석에도 활용될 수 있을 것으로 판단된다.

  • 본 연구에서는 기존에 구축되어져 있는 도로점용 현장 조사를 위한 정보 검색 기능과 현재 실제 현장에서 도로점용 현장조사에 사용하고 있는 문서 및 프로세스 분석을 통하여 도로점용민원 현장조사 방안을 제시하는 것으로 하였다. 국민의 권익과 밀접한 관계가 있는 도로점용민원의 허가여부 판단 및 불법점용현황 등을 파악하기 위해서는 기 허가된 위치등 점용정보에 대한 손쉬운 획득이 중요함에도 불구하고, 점용위치를 나타내는 도면 등이 종이로 관리됨에 따라 업무담당자가 기존 도로점용 정보파악이 용이하지 않는 실정이다. 이에 본 논문에서는 건설인허가시스템에서 관리하는 도로점용정보와 UMPC등 모바일 기기를 활용하여 전자공간과 물리공간이 융합된 도로점용민원 현장조사 도구를 개발하여 활용함으로써, 도로점용 인허가업무의 효율성을 높이고자 하였다.

  • This study was conducted as a basic research to create a sound and vital ecological environment in the city compared to the appearance characteristics of Gap stream(G-stream), which are the main stream of Banseok stream(B-stream), by analyzing the characteristics of waterbirds, including Wild Spot-billed Duck (S-Duck), that live in B-stream built as ecological stream. The waterbird survey was conducted by the line census for 3.2km, Jukdong-bridge to Jamiseon-bridge, from January to August 2018. The analysis of the survey was conducted with Relative species density(RD) of the emerging waterbird species, the Species diversity and Density Per Unit area for 100㎡(DPU). The waterbird survey results of B-stream was conducted 65 times. The five types of water birds that appeared during the survey were Spot-billed Duck(Anas poecilorhyncha), Teal(Anas crecca), Little Egret(Egretta garzetta), Great Egret(Egretta alba), and Grey Heron(Ardea cinerea). As a result, for S-Duck at B-stream, RD was 89.9%, monthly species diversity was simple as 0.3801 in January, 0.5943 in February and 0.3501 in August. The DPU of the S-Duck was 0.165/100㎡ in the B-Stream survey section which was 4.9 times higher than the main stream section, G-stream. The non-freezing zone of the city's small stream is expected to play an important role as a winter stop for wild birds such as S-Duck during the freezing period of the huge stream. For this reason, considering the ecological characteristics of wild waterbirds such as S-Duck when creating ecological stream, a: space and linear selection of waterways which can minimize the impact of natural enemy and increasing the number of walkers, b: management water-friendly plants in the low flow channel, c: arrangement walking-bicycle road will be necessary.

  • During a disease survey in October 2019, leaf spot symptoms with a yellow halo were observed on Korean angelica (Anglica gigas) plants grown in fields in Pyeongchang, Gangwon Province, Korea. Incidence of diseased leaves of the plants in the investigated fields ranged from 10% to 60%. Morphological and cultural characteristics of two single-spore isolates from the leaf lesions indicated that they belonged to the genus Didymella. Molecular phylogenetic analyses using combined sequences of LSU, ITS, TUB2, and RPB2 regions showed distinct clustering of the isolates from other Didymella species. In addition, the morphological and cultural characteristics of the isolates were somewhat different from those of closely related Didymella spp. Therefore, the novelty of the isolates was proved based on the investigations. Pathogenicity of the novel Didymella species isolates was confirmed on leaves of Korean angelica plants via artificial inoculation. This study reveals that Didymella gigantis sp. nov. causes leaf spot in Korean angelica.

  • In the survey from 1992 to 2000, twenty-eight parasitic diseases were observed in major apple producing areas in Korea. The predominant apple diseases were white rot(Botryosphaeria dothidea), Marssonina blotch(Marssonina mali), Valsa canker(Valsa ceratosperma), Alternaria leaf spot(Alternaria mali), and bitter rot(Collectotrichum gloeosporioides and C. acutatum). Apple scab that reappeared in 1990 after disappearance for 15 years was disappeared again since 1997. A viroid disease(caused by apple scar skin viroid) was newly found in this survey. The five diseases, fire blight(Erwinia amylovora), black rot(Botryosphaeria obtusa), scab(Cladosporium carpophilum), Monochaetia twig blight(Monochaetia sp.), and brown leaf spot(Hendersonia mali), which had once described in 1928 but no further reports on their occurrence, were not found in this survey. However, blossom blight(Monilinia mali), brown rot(Monilinia fructigena), and pink rot(Trichothecium roseum), which did not occur on apple after mid 1970s, were found in this survey.
