점오염원의 대기확산에 관한 민감도 분석과 모델링

이화운,원경미,배성정 한국환경과학회 2000 한국환경과학회지 Vol.9 No.1

The sensitivity analysis of two short-term models (ISCST3, INPUFF2.5) is performed to improve the model accuracy. It appears that the sensitivities on the changes of wind speed, stack height and stack inner diameter in the near distance from source, stability and mixing height in the remote distance from source, are significant. Also, the gas exit velocity, stack inner diameter, gas temperature and air temperature which affect the plume rise have some effects on the concentration values of each model within the downwind distance where final plume rise is determined. And in modeling for the atmospheric dispersion of point pollutant source INPUFF2.5 can calculate amount, trajectory of puff and concentration versus time at each receptors. So, it is compatible to analyze distribution of point pollutants concentration at modeling area.

김경진 ․ 장재원 ‧ 이인순 ‧ 박흠대 대구대학교 산업기술연구소 2018 産業技術硏究 Vol.29 No.2

We experimented to investigate the anti-aging effect on the extracts of Asparagus officinalis L. (asparaguse), Eleutherine Americana Merr. (shallot) and Brassica oleracea var. gemmifera (Brussels sprouts). It was respectively extracted for 7 days at 4 ℃ with 70% EtOH and water as solvent and those extracts were determined the concentration of total polyphenolic compound, flavonoid, free radical scavenging as DPPH and catalase activity. In a result, the water and 70% EtOH extract of asparagus were showed over 50% activity of DPPH radical scavenging. The extracts of shallot were had high concentration of polyphenol and flavonoid than the extracts of other sample, but DPPH radical scavenging was found more low activity than the other sample. The extracts of Brussels sprouts were showed lowest concentration of polyphenol and flavonoid among samples, but DPPH radical scavenging was measured highest activity over 60%. And the extract of asparagus and Brussels sprouts were reversely increased the activity of DPPH radical scavenging in a case of the treatment of low concentration. Catalase was confirmed high activity the extract of asparagus tissue and the extract of Brussels sprouts tissue in order. Therefore, Asparagus officinalis L. and Brassica oleracea var. gemmifera have the effect of anti-aging and it is good garnish vegetable eating with meat.

성차와 리더십 : 문헌적 고찰 A Literature Review

조경순,이신자,김호원 숙명여자대학교 아시아여성연구소 2004 아시아여성연구 Vol.43 No.1

최근 여성 리더십에 대한 기업 조직과 학문 분야의 관심이 커지고 있지만 아직 여성 리더십과 관련된 다양한 개념들은 혼용되어 사용되고 있다. 여성 리더와 여성 리더십 연구의 체계적 접근을 위해 생물학적 성과 젠더의 측면에 따른 남녀의 차이와 남녀의 리더십 차이, 그리고 남녀의 리더십 유효성 차이를 경영학 분야에서 연구된 실증연구를 토대로 문헌 고찰을 하였다. 그 결과 성차가 존재하는 가에 대한 물음에 성차는 남녀의 생물학적 차이를 제외하면 성역할 사회화를 통해 만들어지는 것으로 보는 경향이 강한 것으로 나타났다. 리더십의 성차는 리더십 특성과 행위에 차이를 보이는 경향으로, 리더십 유효성에 대한 남녀 차이는 남성이 리더십을 더 발휘한다고 평가하는 경향이 많은 것으로 나타났다. 그러나 리더십과 리더십 유효성의 남녀 차이에 대한 연구는 일관된 결과를 보여주지 못하였으며, 조절변수에 따라 그 차이가 달라질 수 있다고 보고되고 있다. 추가적으로 남녀의 리더십과 리더십 유효성의 차이는 생물학적 성에 의한 차이보다 젠더차에 의한 것이 크며, 이는 성을 남성성과 여성성 및 양성성으로 구분하여 유효성에 대해 남녀 차이를 살펴보는 등의 다양한 연구의 시도들이 필요하다. The literature of leadership research has emphasized the importance of gender issue not only from an academic perspective but also from practical viewpoint. However, the literature seems unclear about many gender-related leadership conceptualizations. This study reviews theoretical and empirical research in organizational behavior,and aims to draw clear a view of the current state of research regarding gender issues in leadership research. Our understanding of the conceptual difference of biological sex and sociological gender of women and men led us to focus on sex- and gender-related differences in leadership, especially in leadership effectiveness. Our review indicates that most of the differences displayed by women- and men-leaders are attributable to their gender- role socialization, rather than their biological sex. It is also found that men-leadership is more effective in general, though the relationship in not very consistent and could be moderated by various factors such as nature of task, composition of the work group, and support from family. Our findings imply that gender differences in leadership are primarily based on socially constructed reality, which suggests future studies on gender issues in leadership to consider masculinity, femininity, and androgyny as major factors that have influence on leadership effectiveness differences.

The electrocardiogram is one of the most widely used diagnostic tools. Especially it is useful to the patients who have cardiovascular disease. Because elderly population are the fastest growing component of national population, I analyzed the frequencies of specific electrocardiogram findings in patients aged 65 years and older living in Gyeong-ju to collecting ECG data. Sinus bradycardia (17.0%) and Left ventricular hypertrophy (25.2%), QT prolongation (30.9%) were the most common abnormalities found in the population as a whole. Left-axis deviation (11.6% vs. 3.1%, p = 0.001) and right bundle branch block (11.9% vs. 4.1%, p= 0.001) were more common in men than women. First-atrioventricular block (2.2% vs. 5.5%, p = 0.025) and T wave abnormalities (4.1% vs. 13.2%, p = 0.001), left ventricular hypertrophy (21.6% vs. 28.0%, p = 0.049) were more common in women. QT prolongation were more common in 75 years and older (26.7% vs. 38.1%, p = 0.001). Left-axis deviation (9.4% vs. 3.9%, p = 0.024) and Right bundle branch blocks (9.8% vs. 3.0%, p = 0.003) were more common in men aged 65~74 years. Left ventricular hypertrophy (20.9% vs. 30.0%, p = 0.025) and T wave abnormalities (4.3% vs. 12.2%, p = 0.002) were more common in women aged 65~74 years. Atrial fibrillation (7.1% vs. 1.1%, p = 0.013) and left-axis deviation 17.6% vs. 2.1%, p = 0.001), Right bundle branch block (17.6% vs. 5.3%, p = 0.001) were more common in men aged 75 years and older. First-atrioventricular block (0% vs. 5.9%, p = 0.020) and T wave abnormalities (3.5% vs. 14.4%, p = 0.008) were more common in women aged 75 years and older. In conclusion, Left ventricular hypertrophy and sinus bradycardia, QT prolongation were most common electrocardiographic findings in as a whole. Left-axis deviation and right bundle branch block, fist-atrioventricular block, T wave abnormalities, QT prolongation were significantly different in age and gender. 심전도는 전 세계적으로 가장 널리 사용되는 진단적 도구로서, 특히 심혈관계 질환이 있는 환자에게 그 유용성이 크다. 현대 사회는 고령화 사회로 노인 인구에 대한 사회적, 의학적 관심이 높다. 이에 본 연구자는 노인 인구에 대한 심전도 자료를 수집하기 위해 동국대 경주 병원 외래 진료실을 방문한 65세 이상 노인 환자 737명을 대상으로 심전도 검사를 시행하였다. 좌심실 비대(25.2%), QT 간격 연장(30.9%)과 동성 서맥(17.0%)을 보인 경우가 가장 많았고, 좌축 편위 (11.6% vs. 3.1%, p = 0.001), 우각 차단(11.9% vs. 4.1%, p = 0.001)의 경우 여자 환자보다 남자 환자에서 빈도가 높았고, 1도 방실 차단(2.2% vs. 5.5%, p = 0.025)과 비정상적인 T파 양상(4.1% vs. 13.2%, p = 0.001), 좌심실 비대(21.6% vs. 28.0%, p = 0.049)의 경우 남자 환자보다 여자 환자에서 빈도가 높았다. 75세 이상 환자 군에서 QT 간격 연장(26.7% vs. 38.1%, p = 0.001)이 65세에서 74세 사이 환자 군에 비해 빈도가 높은 것 외에 유의한 차이는 없었다. 결론적으로 고령 환자에서 비정상적인 심전도 소견으로 좌심실 비대와 QT 간격 연장, 동성 서맥의 빈도가 높았으며 좌축 편위, 우각 차단, 1도 방실 차단 등은 성별, 연령대별로 유의한 차이가 있었다.

김유근,이화운,문윤섭,김해동,원경미,정우식,오인보 부산대학교 환경문제연구소 1997 環境硏究報 Vol.15 No.1

To investigate a horizontal windrose and the mixing height in Masan coastal area, a local atmospheric flow and the concentration of air pollutants were analyzed by abserved data from AWS, airsonde and air sampler. The land-sea breeze model and the ISCST2 model of U. S. EPA(Environmental Protection Agency) were used to predict the concentration of air pollutants such as SO2 and TSP. As a result, during spring the principal wind direction in the Masan region is mainly represented by windrose of the WNW and NW, which can be induced by land breeze and the SE and SSW of sea breeze even if weak wind speed. The mixing height during the measurement was marked with the range from 400 m(0900 LST) to 1450 m(1500 LST), and the height of an inverse layer was presented as the range from 30 m(2100 LST) to 150 m(0300 LST). It is very important to cosider the local wind field for the accurate diffusion and movement of air pollutants in coastal urban area. The atmospheric flow was simulated by the two-dimensional local wind model upon considering the orographic characteristics such as land-sea contrast, mountain valley and urban building. The result of air quality simulated by ISCST2 support that the dispersion pattern of the pollutants in that area was followed as local circulation system in coastal urban area.

In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant
