김정옥,김지영,김효중,김용일,Kim. Jung-Ok,Kim. Ji-Young,Kim. Hyo-Joong,Kim. Yong-Il 한국방재학회 2008 한국방재학회 학술발표대회논문집 Vol.2008 No.1
This study provides considerations for quantitative risk assessment of landslide on GIS technology. It shows how the landslide possibility analysis is linked by GIS modeling to provide loss estimation tools for landslide hazards in support of socio-economic loss reduction efforts. Those risk assessment results can deliver factual damage situation prediction to policy making for the landslide damage mitigation.
데이터 캐로절을 이용한 지상파 DMB 지도서비스 구성방안에 관한 연구
김정옥,가칠오,유기윤,김용일,Kim, Jung-Ok,Ga, Chill-O,Yu, Ki-Yun,Kim, Yong-Il 한국공간정보학회 2007 한국공간정보학회지 Vol.15 No.1
최근 우리나라는 세계 최초의 지상파 DMB 서비스를 제공하였다. DMB 서비스는 국제적으로도 도입 초기단계에 있는 신규서비스이지만 이동 중 수신이 가능한 것을 제외하면 기존의 방송과 비교우위에 있는 장점이 없어 새로운 형태의 컨텐츠와 서비스의 개발이 시급한 시점이다. 이에 본 연구는 DMB를 이용한 위치 및 교통정보 제공 서비스를 착안하고 이를 위한 기본 작업으로 DMB에 적합한 지도서비스 및 지도데이터 전송을 위한 서비스 프로토콜과 데이터 구성을 제안하였다. 이 같은 제안이 구현된다면 DMB의 우수한 이동성과 저렴한 방송 매체를 사용하는 장점으로 기존 방송서비스와 차별화된 핵심 컨텐츠로 자리 잡을 수 있을 것이다. Recently, Korea became the first country which started Terrestrial-DMB service. The DMB service is still at a very early stage throughout the world. At this stage, it is an important issue to develop DMB contents which distinguish DMB from traditional broadcasting by utilizing DMB's mobility. In this paper, we will propose outline of map service through DMB along with related services such as traffic and location information. This outline includes the map service protocol and map data structure for DMB. There is little research at the moment related to it, and this preliminary research enables map service through DMB. A map service would bring DMB a distinct advantage over traditional broadcasting. Moreover, further services based on broadcasting network and mobility would contribute to rapid growth of DMB.

목 적: 소아에서 디스크 전지를 삼키는 사고가 증가하고 있다. 식도에 걸린 경우 식도 궤양, 천공, 누공, 종격동염 등 심각한 합병증을 유발할 수 있으므로 즉각 제거해야 한다. 본 연구에서는 디스크 전지의 내시경적 제거에 있어서 기구에 따른 제거 속도의 차이와 안전성을 비교해 봄으로써 가장 빠르고 효율적으로 제거할 수 있는 방법을 찾아보고자 하였다. 방 법: 1997년 7월부터 2007년 6월까지 디스크 전지를 삼키고 경북대학교병원 소아과에 내원하여 내시경적 적출술을 시도한 24명의 환아를 대상으로 하였다. 평균 나이는 1.5세였고 남아가 9명이었다. 내시경 보조기구로써 magnetic extractor와 풍선을 이용하거나 retrieval net을 사용한 경우를 별도로 비교하여 제거에 걸린 시간과 안전성에 차이가 있는지 검토하였다. 결 과: 전지의 직경과 두께가 $20{\times}2$ mm (또는 2 mm) 인 것이 5건이었고 이 중 3예(60%)에서 식도에 걸려 식도 점막 괴사 또는 궤양을 초래하였다. 직경 20 mm 디스크 전지는 직경 10 mm 전지에 비해 식도에 걸려 손상을 초래하는 경우가 유의하게 많았다(p<0.01). 내시경적 제거방법으로 retrieval net을 사용한 경우가 10명으로 평균 1.5분이 소요되었으며 magnetic extractor와 풍선(또는 condom)을 이용한 경우가 6명이었는데 평균 소요 시간이 3.3분 걸려 retrieval net을 사용할 경우 더욱 신속한 제거가 가능하였다(p<0.05). 결 론: 식도의 디스크 전지는 내시경적 응급 상황으로 즉시 내시경으로 신속하고 안전하게 제거할 수 있도록 조치하여야 한다. 저자 등의 경험에 의하면 retrieval net을 이용한 위장내 이물 제거가 더 효과적이었으나, 시술자의 숙련도와 선호도에 따라 magnetic extractor와 풍선을 이용한 방법 또는 retrieval net을 이용한 제거 등을 선택하여 사용할 수 있을 것이다. Purpose: Any battery impacted in the esophagus must be removed urgently because of the possibility of serious complications such as perforation, fistula, and mediastinitis. The use of endoscopic procedures was compared to find the most rapid, effective, and safe method to remove disk batteries. Methods: The cases of 24 children (9 males, mean age, 1.5 years) that had accidentally ingested disk batteries were reviewed. The patients had visited the Department of Pediatrics, Kyungpook National University Hospital from July 1997 to June 2007 for the removal of disk batteries. Endoscopic removal was attempted using a retrieval net or a magnetic extractor with a balloon (condom). The procedure times for removing the ingested battery were compared. Results: Children that ingested batteries with a larger diameter (20 mm) had a greater chance to have esophageal impaction with serious injury, such as esophageal mucosal necrosis or ulcers, as compared to the ingestion of smaller diameter batteries (10 mm) (p<0.01). Endoscopic removal of disk batteries was attempted either using a retrieval net in 10 children or by using a magnetic extractor with a balloon in 6 children. Endoscopic removal using a retrieval net was more effective (mean procedure time: 1.5 min) as compared to using a magnetic extractor with a balloon (mean procedure time: 3.3 min) (p<0.05). Conclusion: Both procedures, either using a retrieval net or a magnetic extractor with a balloon were effective in removing ingested disk batteries. Based on our experience, an endoscopic procedure using a retrieval net was a more effective method for foreign body removal.

일반적으로 KML 검증도구는 KML 파일을 작성하는 사람이 사용할 기능을 제공한다. 즉, 잘 구성된 문서 여부와 스키마 및 명세서를 준수하였는지를 검증하고, 오류가 있는 부분의 KML 코드 위치만 알려줄 뿐이다. 타인이 작성한 KML 파일을 사용하고자 하는 사람은 KML 검증을 통해 해당 파일의 유효성뿐만 아니라 공간객체의 위치정보, 형태, 개수 등의 일반적 요약사항도 궁금해 한다. 이에 본 연구에서는 기존 검증도구의 검증기능을 모두 포함하면서 OpenLayers 기반의 지도 연동과 도형 및 이미지 기반의 KML 파일 요약정보를 제공하는 사용자 친화적 KML 검증도구를 제안하였다. The KML verification tool supports people who want to produce the highest quality KML file. In other words, it validate that a given KML document is well-formed with respect to XML standard meaning, and conform not only to the KML schema and the specification. Then it's only to notify error code line. People who want to use the KML file written by others would like to know both whether the validity of that file and general summary of feature's location, shape, and number. In this study, we recommended the user-friendly KML validator using OpenLayers and reporting geometries and images of the KML file.

In order to investigate the traditional value of Ewhaju (traditional wine) and to establish the brewing condition, studies on of traditional background and field inquiry were carried out. Scientific evaluation and possibility of revealation of Ewhaju were searched by the experiments of microbial and enzymatic properties of brewed Ewhaju and Nuruk by traditional method. In flora of microorganisms in Nuruk of Ewhaju, Aspergillus oryzae and Hansenula sp. were isolated, and, showed a level of 1.2X10^6 CHU/g, respectively but other microorganisms were not grown in diluted cultivation test. The α-and β-amylase activity of Nuruk were 30.74 and 34.4, respectively and their activities of two amylases were 19.28 and 18.8 at first stage of brewing, 21.21 and 19.80 at 100 day after brewing, and 20.25 and 19.90 at one year aged Ewhaju, respectively. The brewed Ewhaju could be remained with high quality long period without heat treatment or addition of preservatives, also, stored Ewhaju contains remarkably high activity of amylases which might contribute to digestion.
전통 이화주 양조 중의 주요성분 ( 유기산 , 알코올 , Fusel Oil ) 및 관능적 품질 특성

Major quality parameters(organic acids, alcohols, fusel oil and sensory characteristics) of traditional Ewhaju were investigated during brewing. In organic acid contents at immediately after brewing, lactic acid was 155.1 ㎎%, malonic acid was 5.4 ㎎%, succinic acid was 8.9 ㎎%, acetic acid was 7.6 ㎎%, oxalic acid was 1.3 ㎎%, citric and tartaric acid was 27.8 ㎎% and pyruvic acid was 4.8 ㎎ but in 100 days after brewing and one year aged, lactic acid was 1763.3 and 3059.3 ㎎%, malonic acid was 12.3 and 19.3 ㎎%, succinic acid was 11.5 and 23.1 ㎎%, acetic acid was 29.2 and 73.1 ㎎%, oxalic acid was 0.6 and 0.2 ㎎%, citric and tartaric acid was 298.3 and 639.6 ㎎%, and pyruvic acid were 1.1 and 0.3 ㎎%, respectively. All the alcohol contents increased as the fermentation period increased; the ethyl alcohol was only 0.05% at immediately after brewing. In the alcohols content of Ewhaju at 100 days after brewing, the ethyl alcohol, methyl alcohol n-propyl alcohol and iso-butyl alcohol were 5.13%, 47.56 ppm, 37.25 ppm and 19.51 ppm, respectively, Also in the one year aged Ewhaju, the ethyl alcohol was 9.39%, methyl alcohol was 36.34 ppm, Fusel oil was not detected in the first stage of brewing, but it was detected 1.12 ㎎% at 100 days after brewing and 1.18 ㎎% at one year stored sample. A general trend in change of color was almost white immediatly after brewing but a increase in Hunter b value and a` value were observed depending on brewing time prolonged. Taste and overall paratability of Ewhaju after 100 days of brewing were significantly superior(p<0.05, p<0.01).
