양액내 염류농도 증가에 의한 상추뿌리의 마이크로솜 ATPase 활성증가

이경자,강보구,김영기 한국환경농학회 2002 한국환경농학회지 Vol.21 No.2

염류장애에 의한 작물의 생육저해 원인을 밝혀내기 위하여 상추를 대조양액과 대조양액에 30 mM 및 50 mM KNO_3를 첨가하여 염류농도를 높인 양액 등 3가지 조건에서 재배하였으며, 이때 이들 양액의 EC는 각각 1.0, 4.5, 6.5 dS/m 이었다. 뿌리세포의 원형질막 및 액포막에 위치한 H^+-ATPase 활성은 각각에 특이적 저해제인 vanadate와 NO_3를 이용하여 측정하였다. 대조양액에서 재배한 상추 뿌리의 ATPase 활성은 356±1.5 nmol/min/mg protein이었으며, 30 mM과 50 mM KNO_3를 첨가한 양액에서는 활성이 대조활성에 비하여 각각 1.6배, 1.9배 증가하였다. 이것은 상추가 염류장애시 뿌리조직의 ATPase 활성증가를 통하여 적응함을 보여주는 것이며, 활성증가는 주로 액포막 H^+-ATPase 활성증가에 의해 이루어짐을 확인하였다. 마이크로솜 ATPase 활성에 미치는 여러 가지 중금속 이온들의 효과를 측정하였으며, 중금속 이온은 100 μM 농도에서 종류에 따라 활성을 10~25% 저해하였다. 특히, Cu^(2+)는 주로 액포막 H^+-ATPase 활성을 저해함을 확인하였다. 본 연구의 결과로부터 상추는 염류집적 환경에서 뿌리의 ATPase 활성, 특히 액포막에 위치한 H^+-ATPase 활성을 증가시켜 적응하며, Cu^(2+)는 주로 액포막 H^+-ATPase 활성을 저해하는 성분으로 뿌리의 ATPase 활성변화 연구에 유용하게 이용될 수 있음을 확인하였다. In order to investigate the mechanism of growth inhibition by salt stress, lettuces were grown hydroponically in three different nutrient solutions, normal and 30 mM or 50 mM KNO_3-added nutrient solutions, and the electrical conductivities of these solutions were 1.0, 4.5, and 6.5 dS/m, respectively. The activities of plasma and vacuolar H^+-ATPases in the root tissue of lettuce were measured by specific inhibitors, 100 μM vanadate and 50 mM No_3^-, respectively. Microsomal ATPase activity of lettuce grown in the normal nutrient solution was 356±1.5 nmol/min/mg protein. When lettuces were grown in 30 mM and 50 mM KNO_3-added nutrient solutions, total activities of microsomal ATPases were increased by 1.6 and 1.9 times, respectively, and the increases were mainly mediated by vacuolar H^+-ATPase. These results show that lettuces adapt themselves to salt-stressed condition by increasing the activities of H^+-ATPases. Effects of various heavy metal ions were investigated on the microsomal ATPases and various metal ions at 100 pM inhibited the activities by 10~25%. Cu^2+ showed the highest inhibitory effect on the vacuolar H^+-ATPase. These results suggest that lettuce increases the activities of root ATPases, specially that of vacuolar H^+-ATPase, in salt-stressed growth conditions and Cu^(2+) could be a useful tool to control the activity of vacuolar H^+-ATPase.

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.

김민우,변승진,이경은,정소영,조주영,최원자,최찬양,김경 대구대학교 특수교육재활과학연구소 2011 再活科學硏究 Vol.29 No.1

이 연구는 컴퓨터 작업시 의자 등받이 위치가 근육활성도에 미치는 영향을 알아보기 위해 36명의 근골격에 문제가 없는 성인 남녀가 참가하였으며 대상자들은 등받이가 뒤에 있는 의자와 등받이가 없는 의자, 등받이가 앞에 있는 우리들 의자를 무작위로 배정하고 동일한 컴퓨터 작업을 실시하게 하였다. 실험 중, 표면근전도기를 사용하여 의자에 따른 위등세모근, 머리널판근 그리고 척주세움근의 근활성도 변화를 측정하였다. 이 연구의 결과를 종합해보면 등받이가 앞에 있는 의자는 허리 근육의 부담을 줄이지만 목근육에 부담이 늘어나고 등받이가 뒤에 있는 의자와 없는 의자는 허리근육에는 다소 무리가 가지만 목근육에는 부담이 덜하다는 것을 알 수 있었다. 이러한 결과로 환자의 증상에 다라 컴퓨터 작업을 하는 동안 의자 등받이의 위치를 조절하여 치료에 도움이 될 수 있다고 생각되어진다. Objective : In this study, we checked and observed people's change of body muscle and muscle activity who do computer work on different chairs. We set three kind of chairs which one is a stool and another one is the back is fixed, and the other one is the back is fixed in front of chair. Subject : Accounting for 36 health men and women, we divided these people to 3 groups and put them on the three cases(position 1, position 2, position 3). We measured muscle activity of upper trapezius, Splenius Cervics, Erector Spinae from the groups by using surface electromyogram system. Methods : The standard of the electromyogram was 'reference voluntary contraction', and we carried out 'one way anova' to compare muscle activity of three groups. Results : In position 1, reference voluntary contraction of upper trapezius muscle activity was 123.2821%, Splenius Cervics was 141.7526%, and Erector Spinae was 254.5233%. In position 2, reference voluntary contraction of upper trapezius muscle activity was 132.9395%, Splenius Cervics was 141.7526%, and Erector Spinae was 246.6540%. In position 3, reference voluntary contraction of upper trapezius muscle activity was 190.6487%, Splenius Cervics was 270.2332%, and Erector Spinae was 182.1021%. Both upper trapezius and Splenius Cervics muscle activity of position 3 group was higher than the others groups. In position 1 group, Erector Spinae muscle activity was hight than the other groups. And either was position 2 group's(p<0.05). Conclusion : Therefore the chair which is the back is fixed in front is more comfortable for waist muscle but it's not good for neck. And the other chairs are better in waist muscle but not in neck muscle. So far, when we do a computer work, it's prefer to sit on the group 1&2's chairs to reduce neck muscle's stress and sit on group 3's chair to reduce waist muscle's stress.

Lee, Young Ju,Ahn, Hyung Joon,Lee, Gi-Ja,Jung, Gyeong Bok,Lee, Gihyun,Kim, Dohyun,Shin, Jae-Ho,Jin, Kyung-Hyun,Park, Hun-Kuk SPIE - International Society for Optical Engineeri 2015 Journal of biomedical optics Vol.20 No.7

<P>The study was to investigate the changes in biochemical properties of activated mature CD8+ T cells related to apoptosis at a molecular level. We confirmed the activation and apoptosis of CD8+ T cells by fluorescence-activated cell sorting and atomic force microscopy and then performed Raman spectral measurements on activated mature CD8+T cells and cellular deoxyribose nucleic acid (DNA). In the activated mature CD8+ T cells, there were increases in protein spectra at 1002 and 1234 cm(-1). In particular, to assess the apoptosis-related DNA spectral signatures, we investigated the spectra of the cellular DNA isolated from resting and activated mature CD8+ T cells. Raman spectra at 765 to 786 cm(-1) and 1053 to 1087 cm(-1) were decreased in activated mature DNA. In addition, we analyzed Raman spectrum using the multivariate statistical method including principal component analysis. Raman spectra of activated mature DNA are especially well-discriminated from those of resting DNA. Our findings regarding the biochemical and structural changes associated with apoptosis in activated mature T cells and cellular DNA according to Raman spectroscopy provide important insights into allospecific immune responses generated after organ transplantation, and may be useful for therapeutic manipulation of the immune response.

Lee, Seung Woong,Song, Ja-Gyeong,Hwang, Byung Soon,Kim, Dae-Won,Lee, Yoon-Ju,Woo, E-Eum,Kim, Ji-Yul,Lee, In-Kyoung,Yun, Bong-Sik The Korean Society of Mycology 2014 Mycobiology Vol.42 No.2

We investigated a total of 335 samples of Korean native mushroom extracts as part of our lipoxygenase (LOX) inhibitor screening program. Among the mushroom-methanolic extracts we investigated, 35 exhibited an inhibitory activity greater than 30% against LOX at a concentration of 100 ${\mu}g/mL$. Especially, Collybia maculata, Tylopilus neofelleus, Strobilomyces confusus, Phellinus gilvus, P. linteus, P. baumii, and Inonotus mikadoi exhibited relatively potent LOX inhibitory activities of 73.3%, 51.6%, 52.4%, 66.7%, 59.5%, 100.0%, and 85.2%, respectively. Bioassay-guided fractionation led to the isolation of inoscavin A from the methanolic extract of P. baumii, which showed the most potent activity and was identified by spectroscopic methods. Specifically, inoscavin A exhibited potent LOX inhibitory activity with an $IC_{50}$ value of $6.8{\mu}M$.
