The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO<sub>2</sub>-ton and the amount of carbon storage per unit area was 570.8 CO<sub>2</sub>-ton per hectare. Compared to 299.7 CO<sub>2</sub>-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.
朴慶洙,金勝運 全北大學校 1992 論文集 Vol.34 No.-
Information systems are designed around information requirements or needs. However, most existing information systems do not have the capabilities required to support executives' information needs. Excecutive information systems are designed to gether, process, and displasy the information that help senior executives assess their organization's success. The successful implementation of EIS is dependent of efficient information system planning. But the correct and complete information requirements for effective EIS planning and design are frequently very difficult to obtain. In this paper, methodologies for EIS planning and design are analyzed and availability of a methodology is presented through the case study.

박철영,김영설,오승준,우정택,김성운,양인명,김진우,최영길 대한당뇨병학회 2001 임상당뇨병 Vol.2 No.1
연구배경: 당뇨병성 신경병증은 당뇨병 환자에서 흔히 나타나는 합병증으로서 임상 증상은 가볍거나 없을 수도 있지만 많은 경우에 통증, 작열감, 이감각증이나 무감각증 등의 증상을 동반하지만, 이에 대한 명확한 기전이나 뚜렷한 치료방법이 없었다. 최근에 신경세포내 산화성 스트레스의 증가로 신경세포의 손상이 발생된다는 기전이 주목을 받으면서, 당뇨병성 신경병증 환자에게 항산화제인 thiotic acid를 사용하여 좋은 효과를 관찰한 논문들이 발표되었다. 이에 저자들은 한국의 당뇨병성 다발성 신경병증 환자에서 thiotic acid를 경구 투여 후에 신경병증에 의한 효과 및 안정성을 평가하였다. 방법: 모든 대상 환자에게 Thioctic acid 600㎎ 을 1일 1회 아침 식전 30분에 8주간 투여하여 당뇨병성 다발성 신경병증에 대한 TSS의 개선여부에 대한 임상적 유효성 및 이상반응, 내약성, 실험실적 지표의 변화를 통한 안정성을 관찰하였다. 결과: 치료시작 전에 관찰한 환자가 호소하는 증상은 통증이 가장 많았으며 무감각, 작열감, 이상감각 순의 빈도를 보였다. 통증, 작열감, 이감각증, 무감각증의 평균 TSS는 1차 방문시 5.8± 1.8, 2차방문시는 4.4±1.7, 3차 방문시는 3.1±1.1로 사용기판에 따라 통계학적으로 유의한 증상의 호전이 있었다. 또한 TSS의 개선 뿐만 아니라 통증, 작열감, 이감각증 및 무감각증 각각의 증상도 치료전과 치료 4주 후 및 치료 8주 후를 비교했을 때 통계학적으로 유의한 증상의 호전이 있었다. TSS가 1차 방문 시와 비교했을 때 3차 방문시에 30% 이상 개선되었을 때(1차 방문시에 TSS 4인 환자는 2점 이상 개선되었을때) 임상적으로 의미가 있는 반응으로 간주하고 계산한 반응률은 71.3%였다. 결론: 당뇨병성 다발성 신경병중 환자에 대해 항 산화제인 thioctic acid 600㎎ 경구 투여요법은 당뇨병성 신경병증의 증상완화에 유용하며, 안전한 것으로 사료된다. Background: The study was peformed to evaluate the efficacy and safety of oral treatment with the antioxidant α-lipoic acid (Thioctcid??) in diabetic patients with peripheral polyneuropathy. Methods: Thioctacid?? 600㎎ was orally administered once a day for 8 weeks in 61 diabetic patients with peripheral polyneuropathy. Neuropathic symptom(pain, burning, paresthesia, and numbness) were scored before, and of 4 and 8 weeks after treatment. In addition, neuropathy by the physician and patients at the end of treatment. The primary endpoint was the response role after 8 weeks treatment, defined as an improvement in the total symptom score of at least more than 30%. Results: Efficacy was evaluated among forty-four patients who had completely the study according to the protocol and safety was evaluated among all of 61 patients who had taken the study medication. The response rate after 8 weeks was 77.3%. The total symptom score was significantly decreased of 4-week, and further decreased of 8-week. All the individual scores for neuropathic symptom were also significantly reduced of 4-week and further decreased at 8-week. Conclusion: These finding indicate that oral treatment with thioctacid?? at a dose of 600㎎/day for 8 weeks will improve peripheral polyneuropathy in diabetic patients, without causing any serious adverse events.
공공기관 엔터프라이즈아키텍처 성숙도 측정을 통한 정책 시사점 연구
오승운,박현우 한국정보사회진흥원 2008 정보화정책 Vol.15 No.4
정보화 발전과 함께 정보시스템의 투자규모가 확대됨에 따라 중복투자가 발생하고 시스템 간 연계가 복잡하게 되면서 이를 해결할 수 있는 수단이 필요하게 되었다. 이로 인해 엔터프라이즈아키텍처(EA) 도입 및 활용이 의무화 되었다. 더불어 EA의 지속적인 발전 및 고도화 방향 설정을 하기 위한 도구로 범정부 EA 통합 성숙도 모델 v2.0이 개발되었다. 공공기관 성숙도 측정 결과는 2006년 및 2007년 자료를 활용하였으며 2006년 자료는 개별기관의 EA 도입계획을 분석하였고 2007년은 EA 실태조사 및 성숙도 측정 결과를 분석하였다. 연구결과 공공기관 성숙도 수준은 전체 영역 평균 2.0 수준으로 관리영역은 2단계인 정의 수준, 수립 영역은 2단계인 기준수립 수준, 활용 영역은 1단계인 인식 수준이며 국내는 아직까지 EA 활용을 통한 성과를 얻기에는 아직 이른 시점으로 분석되었다. 본 연구는 국내 EA 성숙도 측정을 통한 정책시사점을 얻기 위한 연구로 이를 위해 선진국가의 EA 성숙도 모델 및 측정 제도를 연구하고 국내 EA 성숙도 측정 결과를 분석하였다. 그 결과 국내 EA 성숙도 측정 제도와 공공기관의 EA 현 수준의 문제점 및 개선방향 제시가 이 연구의 목적이다. The size of investment in information systems is magnified along with informatization development. Expenditures are frequently sourced from many different uncoordinated budgets, resulting in significant duplication, redundancy as well as conflict in the demand for resources. As a result of these problems, the introduction and management of Enterprise Architecture (hereinafter referred to as "EA") in organizations has been mandated by law in Korea. The data from 2006 and 2007 has been applied to the public agency maturity assessment results. The 2006 data was used in analyzing EA introduction plans of the individual agencies, and the 2007 data was used in maturity assessment results as well as the actual conditions of EA. Research results of the public agency maturity level showed an overall average level of 2.0: Level 2 (Definition Level) in the Management Area, Level 2 (Baseline Establishment Level) in the Establishment Area, and Level 1(Recognition Level) in the Use Area. The results reflect that achieving performance from EA use is still too early to calculate. The purpose of this study is to get the current political implications on EA via the assessment of domestic EA maturity. For this, we analyzed the domestic EA maturity assessment results and studied maturity models and EA assessment systems of other advanced countries. By using these results, the aim of this research is to recognize the problems and to suggest some directions for improvement of domestic EA maturity assessment systems and the current levels of public agency EA.

Overcrowding of emergency department is a serious and growing problem at St. Mary's Hospital. This has motivated the development of short-stay unit(SSU) as an alternative ward to routine hospital admission and ED discharge. In our hospital a SSU begun to admit patients in January 6, 1997. The SSU received 247 patients from the ED during the eight month interval(January 6, 1997 to August 31, 1997). To examine the utilization of the SSU in ED, we retrospectively analyzed 247 patients admitted in SSU from the ED, and compared the average hours per patient with acute gastroenteritis spent in the ED during the 2-month intervals before(July-August 1996) and after(July-August 1997) the establishment of the SSU. The following results were obtained; 1. The total patients consist of EM 92(37.2%), GS 48(19.4%), IM 24(9.7%), PS 21(8.5%), OS 20(8.1%), OBGY 14(5.7%) and others 28(11.3%) 2. The results of EM patients admitted in SSU from ED 1) Sex ratio of male to female was 1:1.1 and the mean age was 37.3±16years 2) In diagnosis, acute gastroenteritis was 29 cases(31.5%), multiple contusion 14 cases(15.2%), drug intoxication 12 cases(13%), limb laceration 6 cases(6.5%), tendon rupture of hand 6 cases(6.5%), and others 19 cases(20.6). 3) Mean length of stay in ED was 9.18 hours. 4) Among 92 patients to the SSU, 79 patients(85.9%) were discharged, 11 patients(11.9%) formally admitted to hospital and 2 patients(2.2%) transferred to otherhospital. The mean hospital stay time of the patients admitted to SSU was 2.6 days. 3. There was a significant reduction in the average stay time spent in the ED by treat-and-releasing patients with acute gastroenteritis after the establishment of the SSU(from 14.65±9.6 to 7.52±5.4 hr/patient, p<0.001). Conclusively, the establishment of the SSU can shorten the average stay time that treat-and-releasing patients spend in the ED, and reduce the number of admitted patients waiting in the ED.
