정혜정(Hyejung Jung),김홍섭(Hong-Seop Kim),한길(Gil Han),박정욱(Jungwook Park),서영수(Young-Su Seo) 한국식물병리학회 2022 Plant Pathology Journal Vol.38 No.2

Pseudomonas amygdali is a hemibiotrophic phytopathogen that causes disease in woody and herbaceous plants. Complete genomes of four P. amygdali pathovars were comparatively analyzed to decipher the impact of genomic diversity on host colonization. The pan-genome indicated that 3,928 core genes are conserved among pathovars, while 504-1,009 are unique to specific pathovars. The unique genome contained many mobile elements and exhibited a functional distribution different from the core genome. Genes involved in O-antigen biosynthesis and antimicrobial peptide resistance were significantly enriched for adaptation to hostile environments. While the type III secretion system was distributed in the core genome, unique genomes revealed a different organization of secretion systems as follows: type I in pv. tabaci, type II in pv. japonicus, type IV in pv. morsprunorum, and type VI in pv. lachrymans. These findings provide genetic insight into the dynamic interactions of the bacteria with plant hosts.

Purpose: This study was done to provide basic data for nursing intervention to increase communication ability of operating room nurses by identifying the relation among their verbal violence experience, job stress, resilience, and communication ability. Methods: The participants were 136 nurses, working in the operating rooms of six academic and general hospitals located in Seoul and Gyeonggi-Do. Data were collected from May 1st through October 31st, 2016. Collected data were analyzed for frequency and percentage, mean and standard deviation, association among related factors, and stepwise multi-regression using the SPSS 21.0 program. Results: It was found that the strongest factor influencing the communication ability of operating room nurses was persistence (β=.41, p<.001; sub-item of Resilience), followed by support (β=.26, p=.001; sub-item of Resilience). These two sub-items have positive influences on communication ability of operating room nurses. The lack of professional knowledge and skill (β=-.19, p<.001; sub-item of job stress) and verbal violence experience from nurse (β=-.16, p<.001; sub-item of verbal violence experience) have negative influences on communication ability of operating room nurses. These sub-items explained 47.0% of communication ability of operating room nurses. Conclusion: The study results can be used as basic data to develop effective communication. Also, the results show the necessity of developing and applying concrete nursing interventions to improve job satisfaction of operating room nurses.

Purpose: This study aimed to investigate problem behavior and its related factors in school-aged children. Methods: A descriptive correlational study was conducted with 221 mothers of children at 1st to 6th grades. Data were collected from March to April, 2015 using self-report structured questionnaires. Questionnaires included characteristics of sub-jects, Korean Child Behavior Checklist for measuring problem behavior and Children`s Sleep Habits Questionnaire for assessing sleeping habits. Collected data were analyzed by independent t-test, x² test, and multiple logistic regression. Results: In logistic regression analysis, having any maternal job (aOR=2.8, 95% CI=1.1~6.9) and higher daytime sleepiness (aOR=2.9, 95% CI=1.2~7.4) were statistically significant contributors of internal problems. Higher bedtime resistance (aOR=2.2, 95% CI=1.0~4.9) and higher daytime sleepiness (aOR=2.8, 95% CI=1.2~6.3) were statistically significant contributors of external problems. Higher bedtime resistance (aOR=4.3, 95% CI=1.5~12.4) was statistically significant contributors of total problem behavior. Conclusion: School-aged children with sleeping problem are at risk for problem behavior. More attention is need to consider sleeping habits for supporting behavioral improvement in school-aged children.

지눌의 “깨달음의 마음공부”

정혜정 ( Hyejung Jung ) 한국교육사학회 2015 한국교육사학 Vol.37 No.3

본 연구는 지눌의 ‘깨달음의 마음공부’ 체계를 살펴보아 지금까지 분석되지 못했던 핵심들을 짚어내고 현대 마음교육에의 시사점을 찾고자 한 것이다. 지눌에 의하면 깨달음과 마음공부는 선후의 문제로 분리되는 것이 아니다. 마음공부의 시작은 자신의 본래 성품이 고요하면서도 신령스럽게 아는 지혜임을 자각하는데서 비롯되고, 이 깨달음으로 점차 닦아 나가는 것이므로 깨달음이 곧 마음공부의 시작이고 마음공부가 깨달음의 완성이 된다. 지눌의 돈오점수는 돈수적 닦음을 통해본성에 계합하고 뭇 생명을 위하는 광도군품(廣度群品)의 점수가 수반되는 것이므로 그의 마음공부는 원수(圓修).원점(圓漸)으로 칭할 수 있다. 지눌이 말하는 깨달음이란 단순한 언어적 이해가 아니라 신심(身心) 전회(轉回)의 깨달음으로서 명증적인 것이자 심신일원적 성격을 띠며 선교일치적 면모를 보여준다. 선과 교, 삼학의 정(定)과 혜(慧)뿐만이 아니라 자성정혜와 수상정혜의 융섭, 그리고 돈오돈수와 돈오점수가 교묘한 결합을 이루는 선오후수(先悟後修)의 원점(圓漸).원수(圓修) 수행체계는 한국 마음공부 전통의 근간을 이룬다. Jinul says that “when enlightenment first be carried out, the true training is possible.” Enlightenment and training is not being separated as a matter of first and later. In other words the beginning of the training comes from the awareness that one``s own nature is essentially wisdom and spiritual. Because we can go forward gradual training by enlightenment, this enlightenment is soon training and the training after enlightenment is the upcoming completion. There are enlightenment that two kinds of Hae-oh(解悟, sudden enlightenment) and Jeung-oh(證悟, ultimate enlightenment). Jinul(知訥)’s theory of “Sudden Enlightenment and Gradual Cultivation(頓悟漸修)” is to reconcile with nature by “sudden training(頓修)” and to integrate the “sudden training” and “altruistic training”(廣度群 品). It can be referred to as Wonsu(圓修).WonJeom(圓漸). Haeoh(解悟) is not simple verbal understanding but embodied enlightenment to get in the routine body. It integrates mind with body, and also it shows the nature of oneness and the matching of Dogma and Zen(禪敎一致). Also it shows not only the integration of concentration and complete knowledge but also cultivating both concentration and complete knowledge(定慧雙修) of Jaseong(自性) and Susang(隨相). The integrative nature achieves his thoughtful features. This will give the considerable implications for modern education and mind study. At the same time it will implicitly give rise to the direction change.

동학 · 천도교의 개화운동과 ‘하날(天)’문명론

정혜정(Jung, Hyejung) 고려대학교 한국학연구소 2018 한국학연구 Vol.66 No.-

동학운동이 개화혁신운동으로 방향을 전환한 것은 이종일, 양한묵, 장효근 등 독립협회의 개화파와의 교류에서 비롯된다. 이종일은 실학의 계승으로서 동학사상을 인식했고, 동학을 항일세력으로 인식하였으며 ‘동학은 민족의 호흡’과 같다 하였다. 천도교의 개화운동은 우리 고유정신인 하날정신에 기초하여 교정쌍전의 종교문명과 정치문명, 그리고 도덕문명을 지향하는 것이었다. 또한 이는 궁극적으로 개화신생활운동, 성신쌍전과 교정일치, 민권의 공화와 지방자치를 표방한 것이었다. 특히 의암 손병희는 천인(天人)의 하날격(天格)을 통해 인화(人和)를 이룸으로써 이를 국민 전체의 합의체를 이끌어내는 공화의 근거로 삼았고, 자치제를 지속적으로 거론하여 실제 1907년 지방자치제가 홍천군에서 실시되었던 사실이 주목된다. 천도교의 개화운동은 하날문명의 진보에 초점을 둔 국학운동이자 자주독립운동으로서 동학이 지닌 개벽사상의 시대적 변용이었다고 말할 수 있다. The Donghak(東學) movement has turned its direction to the progressive movement. It came from the interaction with people of Korean independence club such as Jong-il Lee, Han-mook Yang, and Hyo-keun Jang. At that time, the progressive movement means the progress of civilization. Jong-il Lee recognized Donghak`s thought as a succession of Silhak(實學) and Donghak(東學) as an anti-Japanese force. He also said that "Donghak(東學) is like a breath of the nation". He argued early on that Donghak(東學) had been a progressive movement since the beginning of the Donghak movement because it was the idea of human equality and innovation thought. Progressive movement(開化運動) of the Donghak(東學)/Chondogyo(天道敎) is based on the Hanal(天) thought of the Cheonin(天人), our own spirit. And it was aimed at the religious civilization, political civilization, and moral civilization of the twin pairs in religion and politics. And it was aimed at the religious civilization, political civilization, and moral civilization of the twin in religion and politics. It is also expressed as a Samdan(三團, three groups) that unifies our people, our spirit and our country. All of these ultimately proclaimed the innovation movement of new life, the integration and completion of spirituality and body(性身雙全), the unity of religion and politics(敎政一致), and republican of civil rights and local government system. The Chondogyo(天道敎) achieved a people`s unity by unity of Harmal and human(天人合一), and it was made the basis of the Republic that led to the consensus of the whole people. In addition, it is noted that by continuously addressing the local government system it was practiced in Hongcheon Gun(洪川郡) in 1907. At that time, the municipal government was recognized as the basis of national independence and the progress of world civilization. The progressive movement of Donghak/Chondogyo was a national academy movement and often an independence movement focusing on the progress of Hanal(天) civilization.

평형 냉동에 의한 물동위원소의 레일리분별

이정훈,정혜정,니암게렐 얄랄트,Lee, Jeonghoon,Jung, Hyejung,Nyamgerel, Yalalt 대한자원환경지질학회 2021 자원환경지질 Vol.54 No.1

Isotopic compositions of snow or ice have been used to reconstruct paleoclimate and to calculate contribution to streamwater using isotopic hydrograph separation as an end member. During freezing and melting of snow or ice, isotopic fractionation occurs between snow or ice and liquid water. Isotopic evolution during melting process has been studied by field, melting experiments and modeling works, but that during freezing has not been well studied. In this review, isotopic fractionation during equilibrium freezing is discussed using the linear relationship between two stable water isotopes (oxygen and hydrogen) and the Rayleigh fractionation. Snow, evaporated from nearby ocean and condensated, follows the Global Meteoric Water Line (slope of 8), but the melting and freezing of snow affect the linear relationship (slope of 19.5/3.1~6.3). The isotopic evolution of liquid water by freezing observed in the open system during Rayleigh fractionation is also seen in the closed system. The isotopic evolution of snow or ice in the open system where the snow or ice is continuously removed becomes more enriched than the residual liquid water by the fractionation factor. The isotopic evolution of snow or ice in the closed system eventually equals the original isotopic compositions of liquid water. It is expected the understanding of isotopic evolution of snow or ice by freezing to increase the accuracy of the paleoclimate studies and hydrograph separation. 고체상의 눈 또는 얼음의 안정동위원소 값은 과거의 기후를 복원하고 동위원소 수문분리의 단성분으로 기여율을 계산하는 데에 사용되어 왔다. 융해와 냉동이 일어나면서 눈 또는 얼음과 액체상의 물 사이의 동위원소 분별작용이 일어나는데, 융해는 상대적으로 현장, 실험 및 모델연구를 통해 연구결과가 제시되어 있지만, 냉동에 대해서는 알려진 것이 많지 않다. 본 논평에서는 평형 냉동이 발생할 때 물의 두 안정동위원소인 산소, 수소의 선형관계 및 레일리분별과정을 통해 냉동에 의한 동위원소 분별과정을 고찰하였다. 해양에서 증발한 수증기에 의해 응축된 눈은 기울기 8을 가지는 지구천수선을 따라 움직이지만, 냉동 및 융해가 발생하게 되면 기울기 19.5/3.1~6.3을 가지는 선형관계를 나타내게 된다. 평형냉동 동안 레일리분별과정에 의해 액체상인 물은 열린 계와 닫힌계에서 같은 동위원소변동을 보여 주었다. 눈 또는 얼음이 제거되는 열린 계에서는 남아있는 물의 안정동위원소와 분별계수만큼의 차이를 가지면서 높은 값을 나타내었다. 닫힌 계에서는 초기 액체상의 물의 동위원소 값으로 눈 또는 얼음은 수렴하였다. 냉동에 의한 눈 또는 얼음의 동위원소변동과정은 고기후 연구 및 수문분리의 정확도를 증가시킬 것으로 기대된다.
