배창용(Chang-young Bae),장암(Am Jang) 대한환경공학회 2018 대한환경공학회지 Vol.40 No.8

최근 기후변화로 인한 홍수, 가뭄, 한파, 폭설 등의 기상재해가 빈번하게 발생하고 있으며, 이러한 현상은 전 지구적으로 더욱 가속화 될 것으로 전망되고 있어 종합적인 대책 마련이 요구된다. 우리나라의 경우 기후변화를 완화하기 위한 노력 없이 현재 추세대로 온실가스를 계속 배출한다면(RCP 8.5) 21세기 후반기(2071년~2100년)에는 평균 기온이 현재 보다 5.7℃ 상승한 16.7℃ 정도로 예상되며, 연평균 강수량 또한 현재 대비 17.6% 증가하는 것으로 예측되어 홍수, 가뭄 등 증가하는 자연재해의 위험으로부터 인명과 재산을 보호하기 위해 보다 전문적인 물관리가 필요한 시점이다. 이에 본 연구에서는 기후변화에 효과적으로 대응하기 위하여 최신 ICT를 활용한 수자원시설(다목적댐)의 과학적인 운영관리 기술과 변화하는 수문상황에 맞춰 수문학적 안정성을 확보하기 위한 충주 다목적댐의 치수 능력 증대 사례를 조사하였다. 또한, 다목적댐의 관리자가 시설운영을 통해 기대할 수 있는 운영수익(용수공급, 수력발전)의 종류와 판매절차 등 수익구조에 대해 살펴보고, 충주 다목적댐의 운영사례를 분석하여 수익을 증대시킬 수 있는 현실적인 방안을 도출하였다. 특히, 2018년도 전력시장의 거래가격 예측을 통해 충주 다목적댐의 연간 전력판매 수익을 전망하고, 시장거래가격이 높은 시간대 발전운영을 통해 발전량의 증가 없이 수익을 향상시킬 수 있는 방안과 그 효과를 계량적으로 제시하였다. Recently, due to the climate change, weather disasters, such as floods, droughts, cold weather and heavy snow, have frequently been occurring, and its frequency is expected to further accelerate around the globe. In Korea, if greenhouse gases continue to be released as the current trend without efforts to mitigate climate change (RCP 8.5), the average temperature will rise 5.7℃ in the second half of the 21st century (2071-2100). Also, annual average precipitation is expected to increase 17.6% compared to current average precipitation, which means more specialized water management is required to protect people and property from the increased risk of flooding and drought. Therefore, in this study, the scientific management technology of water resources facilities (multi-purpose dams) using the latest ICT and the hydrologic stability of changing hydrologic conditions were secured to effectively respond to climate changes. It also examines the types of revenue (water supply, hydro-electric power) that operators of multi-purpose dams can expect from their facility operations, as well as the sales procedures and profit structures. We analyzed the operation cases of the Chung-ju multi-purpose dam and came up with realistic measures to increase our profits. In particular, we were able to predict annual power sales revenue of Chung-ju multi-purpose dam by forecasting the prices in the electricity market in 2018, and to improve profits without increasing power generation volume by operating power generation at the time where market prices are relatively high.

기후변화가 지역의 수자원에 영향을 미칠 것으로 예상됨에 따라 수자원 관리자들은 이에 대응한 적응전략을 수립하는 것이 필요하다. 이에 본고에서는 미국, 영국, 캐나다, 오스트렐리아, 네덜란드의 적응관리의 실태를 검토하였다. 이들 나라들은 현재의 수자원 관리관행, 제도적 장치, 기후변화의 잠재적 수자원 영향에 따라 매우 상이한 적응관리를 하고 있다. 이들 나라들의 비교연구를 통하여 기후변화에 따른 한국에서의 지속가능한 수자원 관리를 위한 정책적 관련성을 도출하였다. As global climate change is expected to influence regional water resources, water resource managers need to establish adaptive management to cope with climate change. We examined adaptive management efforts in the US, UK, Canada, Australia, and the Netherlands. Each country is implementing different levels of adaptation efforts based on current water management practices, institutional arrangements, as well as the varying degree of water availability, current climate effects and expected climate change effects. Based on the comparison of these countries, we suggest policy implications for the sustainable water resource management of Korea under climate changes.

Background: Epidermal cysts (EC) are the most common tumors found on the skin and accompanying inflammation is also frequent. However, the predictors for inflammatory change have not been investigated yet. Objectives: This study was performed to investigate the difference between inflamed and uninflamed epidermal cysts, and to assess associated factors for inflammatory change. Methods: We analyzed the biopsy-proven 1723 epidermal cysts (515 inflamed and 1208 uninflamed) at two tertiary hospitals from 2011 to 2021. Results: The proportion of inflamed epidermal cysts (IEC) and uninflamed epidermal cyst (UIEC) were 29.9 % and 70.1 %, respectively. Inflammatory change was less frequently observed on the face (25.5 %) than the other sites (32.1 %) (p=0.0046). The anatomic location with the highest rate of inflammatory change was back (40.8 %, p=0.0004). Mean duration of inflammatory change from UIEC to IEC on the face was shorter than the other sites (12.5 months vs 17.9 months, respectively, p= 0.0473). On ultrasonography, long axis of IEC (20.7mm) was generally longer than that of UIEC (15.7mm) (p=0.0218). Moreover, Inflammatory change was more frequent on the EC with punctum compared to those without punctum (35.3 % vs 30.3 %, P=0.0471). Conclusion: Based on the location, size and presence of punctum, decision on the optimal treatment strategies can be established when encountering patients with EC.

Hornbeams (Carpinus spp.), which are widely distributed in South Korea, are recognized as one of the most abundant species at climax stage in the temperate forests. Although the distribution and vegetation structure of the C. laxiflora community have been reported, little ecological information of C. tschonoskii is available. Little effort was made to examine the distribution shift of these species under the future climate conditions. This study was conducted to predict potential shifts in the distribution of C. laxiflora and C. tschonoskii in 2050s and 2090s under the two sets of climate change scenarios, RCP4.5 and RCP8.5. The MaxEnt model was used to predict the spatial distribution of two species using the occurrence data derived from the 6^th National Forest Inventory data as well as climate and topography data. It was found that the main factors for the distribution of C. laxiflora were elevation, temperature seasonality, and mean annual precipitation. The distribution of C. tschonoskii, was influenced by temperature seasonality, mean annual precipitation, and mean diurnal rang. It was projected that the total habitat area of the C. laxiflora could increase by 1.05% and 1.11% under RCP 4.5 and RCP 8.5 scenarios, respectively. It was also predicted that the distributional area of C. tschonoskii could expand under the future climate conditions. These results highlighted that the climate change would have considerable impact on the spatial distribution of C. laxiflora and C. tschonoskii. These also suggested that ecological information derived from climate change impact assessment study can be used to develop proper forest management practices in response to climate change.

Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.

Histopathological changes and cadmium accumulations in the gills were investigated in crucian carp (Carassius auratus) exposed to 0, 0.01, 0.1, 0.5 mg/l cadmium (Cd)concentrations for 25 days. After 25 days of exposure, cadmium accumulations increased in each of the different exposure concentrations. Histopathological changes in the gills of curcian carp exposed to cadmium included the acidification of mucous cell, the terminal clubbing of lamellae, the hyperplasia of epitherial cell and the curved of secondary lamellae. The similar histopathological changes were observed once the accumulations of cadmium reached the similar levels found in the present study with the different exposure schemes. Also the acidification of mucous cell in gills appeared when cadmium accumulations reached 5 ㎍/g and more. These results suggested that histopathological changes in the gills, an appearance of mucous cell acidification, be used to estimate the relation between toxic effect and cadmium accumulations in the gills.

N/A Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamole, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension 0.9% showed no change of blood pressure, 5.5% had increased blood pressure 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patients without perfusion defects on SPECT(y=7.1x+48.4r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y=-11.6x+68.9 r=0.17 p〈0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizzness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.
