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 CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-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.

당뇨병성 다발성 신경병증에 대한 Thioctic acid의 유효성 및 안정성에 관한 연구

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.

高級經營者精報시스템 計劃 및 設計方法論 分析

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.

PLT and PLZT feroelectric thin films were fabricated on ITO substrate by rf magnetron sputtering. Pressure was 30mTorr, rf power was 180W and substrate temperature was varied from room temperature to 500℃. In this case, PLT had the highest dielectric constant of 120 at 500 ℃, oppositly PLZT had the highest dielectric constant of 312 at room temperature. I-V characteristics of PLZT film were shown that leakage current of PLZT film deposited at room temperature was below 3μA at 100V.

Tuberculosis, a chronic infectious granulomatous disease, is preumed to be quite a rare entity. Because of the development of chemotherapy and the improvement of nutritional conditions, incidence of tuberculosis have reduced. For these reasons, tuberculosis may be overlooked in the differential diagnosis whenever dealing with a submandibular swelling. Diagnosis of tuberculous lymphadenitis consists of historical data, physical findings, laboratory tests and histologic examination. The treatment of choice seems to be surgical excision and long term antituberculosis chemotherapy. Surgery provides a rapid tissue diagnosis, because the histological examination of the excisional biopsy is the most reliable diagnostic test. This is the report of a case of tuberculous cervical lymphadenitis on left submandibular area with no evidence of the involvement of lung.

It has been documented that periodontopathic bacteria are also implicated in endodontic infections. 16S rDNA gene-directed PCR was to examine the prevalence of periodontopathic bacteria including Actinobacillus actinomycetemcomitans (Aa), Prevotella intermedia (Pi), Prevotella nigrescens (Pn), Porphyromonas gingivalis (Pg), Porphyromanas endodontalis (Pe), and Treponema denticola (Td) in the root canals of 36 endodontically infected teeth having apical lesions with or without clinical symptoms like pain, swelling, and fistula. 1. In 36 infected root canals, most frequently detected bacterial species was Pg (61.1%), followed by Td (52.8%) and Pe (38.9%). 2. Of 36 infected root canals, Aa was detected in 6 canals (16.7%) of the teeth, all of which showed clinical symptoms. 3. Of 36 infected root canals, Pi and Pn Were found in 4 (13.9%) and 5 (33.3%), respectively. Notably, prevalence of Pn in the symptomatic teeth was 50.0%. 4. One of black-pigmented anaerobic bacteria (BPB) including Pi, Pn, Pe, and Pg was detected in all of the teeth that showed pain or especially swelling but not fistula. It was, however, found that prevalence of BPB in the asymptomatic teeth or the teeth with fistula was only 40%. 5. Pe and Pg were detected in the teeth regradless of the presence or absence of symptoms. High prevalence of BPB in the symptomatic teeth but low in the asymptomatic teeth suggested that BPB may play an important role in the pathogenesis of periapical lesions.
