Purpose: The purpose of this study was to check the stress, stress and coping ability of nursing college students and to identify factors that influence college life adjustment. Method: This study was a descriptive research study to confirm the correlation between stress, stress response, coping ability, and college life adaptation of nursing college students, and to analyze the factors that influence college life adjustment. The data collection period was from August 17 to 23, 2020, for one week, the researcher directly explains the purpose and purpose of the study to 221 nursing college students nationwide, and online surveys to those who have agreed to participate in the study. The collected data were analyzed using SPSS Win 20.0 program. Results: Adaptation to college was negatively correlated with stress (r=-.285, p<.001), stress response (r=-.258, p<.001), and coping ability (r=.512, p<.001) had a positive correlation. The most significant factor influencing the study subjects' adaptation to college life was coping ability (β=.473, p<.001), followed by stress (β=-.185, p=.002) in the order of The explanatory power of the factors affecting the subject's adaptation to college life was 28.9%. Conclusion: As a result of this study, it means that nursing students' adaptation to college life has less stress and stress response, and higher coping ability increases college life adaptation. The factor that influenced the adjustment to college life was the most significant factor, followed by stress. In order for nursing students to adjust to college life smoothly, it is thought that coping measures to reduce stress and stress responses and overcome them are necessary.

모델식물 애기장대에 대한 훈증제 메틸브로마이드의 약해발생 및 N-acetyl-L-cysteine, L-glutathione, indole-3-acetic acid의 약해억제 효과

김경남,김채은,박정은,유진성,김우성,전황주,김준란,이성은,Kim, Kyeongnam,Kim, Chaeeun,Park, Jungeun,Yoo, Jinsung,Kim, Woosung,Jeon, Hwang-Ju,Kim, Jun-Ran,Lee, Sung-Eun 한국환경생물학회 2021 환경생물 : 환경생물학회지 Vol.39 No.3

본 연구는 식물검역 분야에서 주요하게 사용되고 있는 메틸브로마이드 훈증제로 인해 발생하는 약해를 저감하기 위한 물질을 모델식물인 애기장대를 이용하여 스크리닝하였다. 사전연구를 통하여 메틸브로마이드 훈증제의 식물 독성 메커니즘으로 활성산소발생와 식물 성장 호르몬인 옥신의 식물체 내 분배억제효과가 발생하는 것을 바탕으로 하여, 약해 저감물질후보군으로 활성산소를 제거하는 역할을 하는 ROS scavenger 2종(NAC, GSH)과 옥신을 훈증제 처리 전 애기장대에 처리한 후 약해의 저감 정도를 육안평가와 더불어 관련 유전자의 발현을 확인하였다. 연구 결과 메틸브로마이드에 의해 유도된 약해는 옥신보다는 활성산소를 저감시키는 물질후보군들에서 약해 저감효과가 나타났다. 이 중 GSH을 이용하여 농도구배하여 전처리하였을 때, 5 mM GSH 전처리 후 메틸브로마이드 훈증시 약해 저감효과가 두드러졌다. GSH 전처리 시 식물체 내에 MBF1c와 HSP70 유전자 발현이 증가하는 것을 확인하였으며, 이는 메틸브로마이드 훈증으로 유도되는 약해를 방어하는 역할을 담당하였을 것이라고 평가된다. 따라서, 식물검역 훈증제 메틸브로마이드에 의해 발생하는 약해를 저감하는 데 GSH의 사용가능성을 평가하였으며, 이를 기반으로 다양한 식물체에 적용하여 수출입 시 약해로 인한 경제적 손실을 감소시킬 수 있기를 기대한다. Understanding the phytotoxic mechanism of methyl bromide (MB), an essential fumigant during the quarantine and pre-shipment process, is urgently needed to ensure its proper use and reduce international economic losses. In a previous study, two main MB-induced toxic mechanisms such as reactive oxygen species (ROS) and auxin distribution were selected by analyzing transcriptomic analysis. In the study, a 3-week-old A. thaliana was supplied with 1 mM ROS scavengers [N-acetyl-L-cysteine (NAC) or L-glutathione (GSH)] and 1µM indole-3-acetic acid(IAA) three times every 12 h, and visual and gene expression assessments were performed to evaluate the reduction in phytotoxicity by supplements. Phytotoxic effects on the MB-4h exposed group were decreased with GSH application compared to the other single supplements and a combination of supplements at 7 days post fumigation. Among these supplements, GSH at a concentration of 1, 2, and 5mM was suppled to A. thaliana with MB-fumigation. During a long-term observation of 2 weeks after the fumigation, 5 mM GSH application was the most effective in minimizing MB-induced phytotoxic effects with up-regulation of HSP70 expression and increase in main stem length. These results indicated that ROS was a main key factor of MB-induced phytotoxicity and that GSH can be used as a supplement to reduce the phytotoxicity of MB.

제국의 식민지·점령지 지배와 '전후보상' 기록의 재인식 조선의 식민지지배·보상처리 결재구조와 원본출처를 중심으로

김경남,Kim, Kyung-Nam 한국기록학회 2014 기록학연구 Vol.0 No.39

본고는 일본 제국의 식민지 지배와 '전후보상'처리와 관련하여, 일본 제국주의와 조선 식민지, GHQ와 점령지 일본에서 이루어진 결재 과정과 이 과정에서 생산된 기록 원본의 출처를 밝히는 것을 목적으로 한다. 1910년부터 1952년까지를 대상으로 역사학과 기록학의 관점에서 분석하였다. 이 연구에서는 식민지 지배와 그 처리문제를 시공간적으로 연속선상에서 파악함으로써 제국과 식민지 점령지 기록에 대한 인식의 지평을 확대할 수 있는 기반을 마련하고자 하였다. 1910년부터 1945년까지 일제의 식민지 조선에 대한 강점지배에 대한 기록과 1945년부터 1952년까지 GHQ 점령기의 '전후보상'처리에 대한 결재원본은 한국, 일본, 미국 등에 분산 보존되어 있다. 가장 큰 원인은 일본제국정부와 조선총독부, GHQ와 일본종속정부의 결재구조에 있다. 즉, 중요정책, 인사, 예산에 대한 결재는 제국 본국에서 처리되고, 그 시행에 관한 결재는 식민지 및 종속국에서 처리되는, 상명하달식 이중결재구조 때문이다. 이에 따라 결재 원본도 일국에 완결적으로 보존되는 게 아니라 제국과 식민지 종속국가에 각각 분산 보존되어 상호 보완적 관계를 갖고 있다. 특히 최근 한일간 외교문제로 부각되고 있는 강제 동원된 조선인 미불금 문제는 GHQ의 정책결정과 일본정부의 정령 시행으로 공탁처리되어, '채무'에서 '경제협력'으로 둔갑해 버렸다. GHQ-일본의 상명하달식 결재시스템에 의해, '전후보상'을 위한 기본적인 원본기록 역시 미국과 일본에 각각 분산 보존 되게 되었다. 그러므로 1910년부터 1952년까지, 일제에 의한 식민지지배와 '전후보상'을 둘러싼 문제는 의사결정 프로세스와 기록의 출처 분석 등을 통해 시간적 공간적 측면에서 구조적 종합적으로 재인식될 필요성이 있다. This article aims to inquire into the decision making system and the sources of the original documents made by means of it in Imperial Japan, the colonial Chosun, GHQ, and the occupied Japan in terms of the post-war treatments of compensation on the Japanese colonial rules. It deals with them from 1910 to 1952 in the perspective of history and archivistics. This article attempts to establish the foundation on which the perception of the documents made in the Imperial Japan, its colony, and the occupied territory would be widened by placing the colonial rules and the compensation on them into a continuous line. The records of Japan's forced occupation of Korea during 1910-1945, and the original records documenting the decision making process of post-war compensation under GHQ, 1945-1952, have been dispersed in Korea, Japan and the United States. This dispersed preservation was mainly due to the complicated decision-making process among Governor-General of Chosun, the Japanese Imperial government, and the GHQ. It was the top-down styled, dual decision making system, in which the critical policies, personnel, and budget had been decided in Imperial homeland, while their implementations were made in the colonies. As a result, the records documenting the whole process of domination have been preserved dispersedly in Japan and its colonies. In particular, the accounts of not yet paid Korean workers that was forced to mobilize in Japan's colonial periods, which is emerging as the diplomatic conflict between Korea and Japan, had been dealt in the decrees of the Japanese government and policy-making of GHQ. It has already been changed to the problem as 'economic cooperation' from the 'debt'. Also, the critical records for post-war compensation were preserved dispersedly in the United States and Japan under the top-down decision making process of GHQ-Japan. Therefore, the dispersed records of 1910-1952 about the colonial rules by the Imperial Japan and the post-war compensation on them must be re-investigated for the adequate documentation in the context of time and space.

자연실온 및 변온환경에서 퍼레니얼 라이그래스 신품종 8종류의 발아특성 및 일일 발아패턴 비교

김경남,Kim, Kyoung-Nam 한국잔디학회 2010 한국잔디학회지 Vol.24 No.2

본 연구는 자연실온 조건에서 퍼레니얼 라이그래스 신품종의 초기 발아특성 및 발아패턴을 파악하고, 변온 및 자연실온 환경에서 그 차이점을 비교 분석해서 잔디밭 조성 시 실무에 응용할 수 있는 기초 자료를 제공하고자 시작되었다. 퍼레니얼 라이그래스 종자의 발아율, 발아패턴 및 발아특성은 생육환경 및 품종에 따라 차이가 크게 나타났다. 자연실온 환경에서 발아력은 ISTA 변온과 약간 다르게 나타났고 최종 발아율은 66.25~93.50% 사이로 다양하였다. 최종 발아율이 66.25%인 'Brightstar SLT' 품종을 제외한 모든 품종의 발아율은 실무적으로 요구되는 최소 기준인 75% 이상으로 양호하였다. 자연실온 조건에서 퍼레니얼 라이그래스의 발아패턴은 최초 발아의 경우 ISTA 변온에 비해 2~4일 정도 늦은 치상 후 6~8일 사이에 시작되었다. 최초 발아 시기는 공시 품종 간 1일 정도 차이가 있었으며, 'Sonata' 품종을 제외한 모든 품종은 6일과 7일 사이에 발아가 시작되었다. 발아율 50%에 도달한 기간은 최초 발아 후 2~5일 경과 후인 치상 후 8~12일 사 이로 ISTA 변온에 비해 4~5일 정도 늦게 나타났다. 또한 자연실온 조건에서 실무적으로 요구되는 발아율 75% 도달기간은 ISTA 변온에 비해 품종에 따라 2.07~5.70일 정도 늦은 치상 후 10.08~13.70일 사이로 나타났다. 공시 품종 중 75% 발아율 도달 기간이 가장 빠른 품종은 'Pennant II' 품종이었다. 반대로 가장 느린 품종은 'Catalina II' 품종으로 가장 빠른 'Pennant II' 품종에 비해 3.62일 정도 늦게 도달하였다. 퍼레니얼 라이그래스 품종 간 발아특성 및 발아패턴 결과를 종합적으로 고려할 때 자연실온 조건에 'Pennant II' 및 'Brightstar II' 품종이 가장 우수한 것으로 판단되었다. 그리고 이러한 생리 생태적 특성 차이 및 비교 데이터는 골프장 등 잔디밭 조성 시 정확한 설계 및 양질의 식재관리 등에 실무적인 기초 자료로 유용하게 활용될 수 있을 것이다. Research was initiated to investigate the early establishment characteristics and germination patterns of perennial ryegrass (PR, Lolium perenne L.). Eight cultivars of PR were evaluated in the study. Experiment was conducted under a room temperature condition of $6^{\circ}C$ to $23^{\circ}C$ (natural conditions). Daily and cumulative germination patterns were measured and analyzed on a daily basis. Significant differences were observed in germination pattern, days to the first germination, days to 50% germination, days to 75% germination, and germination percentage with different environments and cultivars. Germination percentage was variable with cultivars at the end of study. It was 66.25 to 93.50% under natural conditions. There were considerable variations in the early germination characteristics and germination pattern among the entries according to different conditions. The first germination was initiated between 3 and 5 DAS (days after seeding) under ISTA (International Seed Testing Association) conditions. But it started between 6 and 8 DAS under natural conditions, being 2 to 4 days later as compared with that under ISTA conditions. It was 8 to 12 DAS that reached to days to the 50% germination, which was 2 to 5 days after the first germination. Days to the 75% germination were 10.08 to 13.70 DAS under natural conditions, being 2.07 to 5.70 days slower as compared with ISTA conditions. 'Pennant II' was the fastest cultivar. But the slowest was 'Catalina II' that was 3.62 days later than 'Pennant II' under natural conditions. Considering days to the first germination, days to 75% germination, and germination pattern etc, 'Pennant II' and 'Brightstar II' were regarded as excellent cultivars under both conditions. From this study, information on differences in germination characteristics and patterns would be usefully applied for golf course design and construction, when established with PR.

지역방재력 평가에 관한 연구(2): 강원도를 중심으로

김경남,권건주,백민호,Kim,Kyoung-Nam,Kwon,Gun-Ju,Baek,Min-Ho 한국방재학회 2009 한국방재학회논문집 Vol.9 No.1

지금까지 우리나라의 재난관리 활동은 재난관리의 주체가 전적으로 국가 및 지방자치단체인 공공행정이 책임이라는 인식하에서 추진되었지만, 대형화되는 재난현장에서 공공분야만의 재난관리 역량으로는 실제 재난발생시 기대했던 효과를 내지 못하고 있는 것이 현실이다. 따라서, 본 연구는 이를 분석하기 위해, 사전에 주민대표(이, 통장)를 대상으로 대비-대응-복구 단계별 `주민개인-주민공동-민관협동` 에 의한 재난관리 대비태세를 중심으로 인터뷰를 실시하였으며, 이를 바탕으로 지역자율방재단원들이 지역방재력량을 발휘하기 위한 요소를 `위험 인지능력, 피난유도능력, 자주피난 대비능력, 방재체제 정비정도, 감시경계능력, 정보전달능력` 등 6가지로 분류하여 설문조사를 실시하고 분석하였다. Until now, Korea carried out disaster management under the perception that the central government or the local government bodies are totally responsible. However as the size of disasters become larger, the capacity of the public disaster management did not live up to the expectations. To analyze this issue, this research conducted interviews on disaster response readiness by `individual resident-residents cooperation-public/private collaboration` according to each preparedness-response-recovery stage, as resident representatives (Head of Ri, Head of Tong) as subjects. Based on the interviews, surveys were conducted to deduct the necessary factors needed for the general residents to exhibit disaster prevention capabilities. The surveys consist of 6 factors-risk perception, evacuation inductively, individual evacuation response, disaster prevention system, lookout & precaution, information communication.

USGA 지반구조에서 한지형 잔디의 여름 고온기 적응력, 색상 및 연중 녹색 유지기간 비교

김경남,Kim Kyoung-Nam 한국조경학회 2005 韓國造景學會誌 Vol.33 No.5

Research was initiated to investigate turf performance under USGA soil system. USGA system 45 centimeters deep was built with rootzone layer, intermediate layer, and drainage layer. Six turfgrass entries were comprised of 3 blends and 3 mixtures from cool-season grasses (CSG). Turfgrass color and quality ratings were best in spring and fall, especially early May to early July and late August to early November. Kentucky bluegrass (KB) consistently produced the greatest performance, while perennial ryegrass (PR) the poorest. Intermediate turf performance between KB and PR was observed with tall fescue (TF). Among CSG mixtures it increased with KB but decreased with PR. There were considerable variations in summer turf Performance. No summer drought injury was found in KB and TF. However, PR showed poor performance through summer as compared with others. Among mixtures, it decreased with PR. It was suggested that PR mix in less than $20\%$ in the mixtures to have an acceptable quality in summer. Cultural intensity also affected it. With lowering mowing height, KB of rhizomatous-type in growth habit kept good quality, while PR and TF with bunch-type in growth habit poor quality. Mowing quality was greatly different among CSG. KB produced clean-cut surface, but PR unclean one. If had an intermediate mowing quality between KB and PR. A great difference in green color retention was observed among CSG. The longest CSG was PR that kept green for 339 days, while the shortest one TF for 267 days. KB continued to keep green for 290 days. The mixtures kept green in color for 292 to 315 days, depending on turfgrass mixing intensity. The greater the PR in content, the longer the green color duration. These results demonstrate that KB was the best and PR the worst among CSG grown in USGA system under a domestic climate, in regards of turf quality, color, mowing quality, summer turf performance and green color duration. KB and TF are most adequate for high-maintenance and low-maintenance area, respectively. In case of mixtures for high-quality turf, it was desirable to use KB-based mixture with PR of below $20\%$ in seeding rate.
