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.

The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

박운용,차성렬,김진수 東亞大學校 建設技術硏究所 2000 硏究論文集 Vol.24 No.2

On this study, using the new technique with GPS which is more effective than conventional method and has the capability to detect the range in the order of ppm, the measurement for monitoring the deformation of a dam structure which provides agricultural water as well as living water. With the selection of the test field, an embankment which had been damaged and therefore was restored by mortar, GPS measurement was carried out to investigate the stability of the structure when pondage has maintained specific quantity. Therefore, the measurements of baseline vectors in reference network was done total three times. As results of the experiments, the standard deviation showed maximum ±4.5mm. In addition, not only did the deformation elements analyzed through dividing as triangular networks and then observing by GPS static methods present. Δ=1E-04-9E~05, γ=2E-04-9E~05 but also the deformation direction was estimated with the method which analyzes the differences among the deformation elements, such as north, east and height (Δn, Δe, Δu) transformed into local coordinate system. Consequentially, it is concluded that the dam should be need to closely safe examination.

중국 대학생의 사회신뢰에 대한 영향요인 분석

The purpose of this research is to examine primary factors, presented in existing research, that influence social trust and analyze whether they exert significant influence on social trust in china. This Paper reveals that : First, in the relation of individual personality and social trust, altruism has negative effect(-) about social trust but the recognition of human nature has positive effect(+) about it. Second, environment satisfaction and the trust within the organization exerts positive(+) influence on it. Third, a level of an academic background, ideology, income have relation with a social trust level of groups divided by them. In the course of this research, I found that it is difficult to grasp effect factors of social trust and improving trust level at short period is more than that. And I come to conclusion that a suitable use of control memorial services by policy is helpful to elevate social trust.

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.

박운용,차성렬,배경호 東亞大學校建設技術硏究所 2004 硏究論文集 Vol.28 No.1

The plenty of availability and high precision of GPS CORS is the reason why it become important more and more in the fields of surveying widely. In this study. I extracted the arbitrary point's coordinate which is using GPS CORS data. now served in RINEX FORMAT via Inter-Net, with observation network of the existing triangulation and GPS CORS data. Then. with this arbitrary point as reference station. RTK GPS was performed. And I will study VRS-GPS concept which reduces the time and cost in the fields of surveying.
