유아교사의 대인관계 스트레스와 이직결정 경험에 대한 연구

최예슬(Choi, Ye-Seul) 한국어린이교육문화비평학회 2014 영유아교육과정연구 Vol.4 No.2

본 연구는 대인관계 스트레스로 이직을 경험한 유아교사들의 대인관계 갈등의 원인과 이직에 미치는 영향에 대해 알아보는데 그 목적이 있다. 이직 현상에 내재되어 있는 의미를 보다 심층적으로 이해하고 이직 대책 방안 수립에 필요한 기초자료를 제공하고자 한다. 유아교사들의 대인관계 스트레스는 학부모, 동료교사, 원장과의 갈등에서 비롯되는 것으로 나타 났다. 연구 참여자들은 이직결정에 가장 큰 영향을 주는 요인으로 원장과의 관계를 꼽았으며 그중 에서도 인격모독적인 상처 주는 언행으로 유아교육기관을 떠나는 가장 직접적인 원인으로 지적되고 있다. 유아교사들은 원만한 관계형성을 위하여 의사소통의 기회가 확대 되어야 한다. 또한 유아교육기 관은 서로 협력하고 보호하며 격려해주는 교육적인 분위기를 조장하고 공식적, 비공식적인 친교적 활동에 노력을 기울인다면 교사의 관계 개선 뿐 아니라 이직의 수준을 낮추어 건강한 조직문화가 형성 될 것이다. The purpose of this study was to examine the interpersonal stress and turnover of seven early childhood teachers, who had turnover experience due to interpersonal stress, by having in-depth interviews. It’s specifically meant to listen to their stories to have a profound understanding of the meaning of their turnover experience to lower the level of stress and the frequency of turnover to make a contribution to the qualitative development of early childhood education, as there are severe stress and frequent turnover in early childhood education institutions. The interpersonal stress of the early childhood teachers could be classified into three: conflicts with parents, conflicts with colleagues, and conflicts with directors. The participants pointed out relationship with directors as the biggest factor to affect turnover decision making. Early childhood teachers should be given more chances of communication to facilitate their relationship building, and the community of early childhood teachers should turn into an organization where the members approve of one another, share their ideas and work together. Directors should back them up properly with interest, and every early childhood education institution should try to create a collaborative, supportive, encouraging and educational climate and to promote a friendly relationship among every organizational member both formally and informally, which will serve, in turn, to improve their relationship, curb turnover and ultimately create a healthy organizational culture.

최예슬 ( Choi Ye Seul ),정윤 ( Chung Yoon ),이견직 ( Lee Kyun Jick ) 한국시스템다이내믹스학회 2017 한국시스템다이내믹스 연구 Vol.18 No.2

There have been various studies related to length of stay which has a direct effect on the national health expenditure so far. However, the majority of studies have only identified the factors affecting length of stay and tried to find the correlation. Based on systems thinking methods, this study tried to explain the causal relation of influencing factors of length of stay. In particular, this study examined the overall feedback structure by constructing a causal map using influencing factors to overcome the existing methodological limitations. Result suggests a fundamental revision of the lower medical cost system will be more helpful in enhancing the quality of medical services and the profitability of hospitals and in improving the financial condition of the National Health Insurance in the long term. Major contribution of this study is that this research offered a holistic view by integrating the medical fee payment system of the country, medical quality in hospitals, and the relation between the household budget for medical fees of patients and the financial condition of the National Health Insurance.

Company-Level Technological Innovation in DPR Korea: Focusing on Kumkhop General Foodstuff Factory for Sportspeople

강호제 한국과학사학회 2022 한국과학사학회지 Vol.44 No.2

The ‘Kumkhop General Foodstuff Factory for Sportspeople’ has launched techno-logical innovation policies in North Korea's food industry since 2010. The poli-cies have been connected to the national development strategies, which means transferring military resources to civilians. This study examined how the econom-ic development strategy emphasizing science and technology was implemented in individual companies in the food industry. It included automation and changes based on IT and CNC technology. In addition, it was confirmed that the rights of individual companies are being strengthened in the economic system that North Korea is developing, the Socialist System of Responsible Business Operation. Small but continued changes in the North Korean economy are shown by depict-ing some micro-activities of individual companies, corresponding to macro-policies. It could be possible that North Korea has been moving toward a techno-logical innovation-friendly society.

연구자로서의 교사 되기 과정에 대한 자문화기술지

최예슬 ( Choi Ye Seul ) 한국교육인류학회 2021 교육인류학연구 Vol.24 No.4

이 글은 연구자인 ‘나’가 ‘연구자로서의 교사’로 성장하는 이야기를 그린 자문화기술지이다. 나는 이 글에 내 삶의 모습을 생생하게 재현하고자 했고, 이 글을 읽는 독자들이 나의 자전적 이야기를 통해 연구자로서의 교사 되기 과정 속 진솔한 체험과 그에 관한 의식들에 주목하기를 바랐다. 이 글은 독자들이 연구자로서의 교사 삶의 문화적 맥락을 깊이 이해하는 데에 도움을 줄 수 있을 것이다. 나는 연구자로서의 교사 되기 과정을 ‘태어나기’, ‘날아보기’, ‘떨어지기’, ‘날아가기’라는 의미적 틀로 제시하였다. ‘태어나기’에는 교육의 목적 찾기에 대한 열망으로 연구자 삶을 시작한 이야기가, ‘날아보기’에는 연구자로서의 교사상에 관한 긍정적 자아개념이 형성·발달되며 연구자로서의 교사로 성장을 해나가는 이야기가, ‘떨어지기’에는 연구자로서의 교사상에 관한 부정적 자아개념이 형성되며 성장에 어려움을 겪는 이야기가, ‘날아가기’에는 좌절을 극복하고 다시, 진정한 연구자로서의 교사가 되기를 꿈꾸는 이야기가 담겨 있다. 나는 연구자로서의 교사들이, 이상으로만 여기던 생각들을 우리 교육의 현실로 만들기 위해 끝없는 비상을 꿈꾸기를 바란다. 수많은 실속(失速)을 경험하더라도 날갯짓을 멈추지 않고, 푸른 하늘을 더 높이 더 멀리 비행하며 숭고한 목표를 추구하는 조나단 갈매기 무리처럼 빛나기를 빈다. This study is an autoethnography that tells the story of my growing up as a ‘teacher as researcher (TAR).’ The process of becoming a TAR is reproduced in this article. I tried to honestly describe my experiences and perceptions related to the process. Through this, I expect that readers of this article would be able to better understand the cultural context of the life of TARs. In this article, the growth period of TAR is divided into four stages of ‘Birth,’ ‘Flying,’ ‘Falling,’ and ‘Flying high.’ In ‘Birth,’ there is the story of a teacher trying to be a passionate TAR. In ‘Flying,’ there is the story of growing up as a TAR by forming and developing a positive self-concept regarding the image of TARs. In ‘Falling,’ there is the story describing difficulties in growth as a TAR by forming a negative self-concept. In ‘Flying high,’ there is the story of overcoming setbacks and dreaming of becoming a genuine TAR again. I want TARs to dream of a leap forward in order to make a story that was only dreamed of as an ideal to become a reality in our education. Even after experiencing numerous stalls, I hope that they will not stop flapping their wings, fly higher and farther in the blue sky, and shine like a flock of Jonathan Seagulls pursuing a noble goal.

이채영,최예슬,이희두,김영호,홍성택,우선희,이정란,Lee, Chae Young,Choi, Ye Seul,Lee, Hee Doo,Kim, Young Ho,Hong, Seong Taek,Woo, Sun Hee,Lee, Jeongran 한국잡초학회 한국잔디학회 2018 Weed & Turfgrass Science Vol.7 No.3

본 연구는 2017년 2월부터 4월까지 충북지역 제초제 저항성 논잡초 발생현황을 조사하기 위하여 11개 시 군 289지점에서 토양시료를 채취하였다. 충북지역의 제초제 저항성 논잡초의 발생을 조사한 결과, 시 군별 최우점 잡초는 물달개비이었고, 그 다음은 강피였다. 충북지역의 제초제 저항성 잡초 발생비율과 면적은 각각 80.6%, 28,272 ha로 지난 2012년 보다 3배 증가하였다. 옥천군의 저항성 발생율이 93.8%로 가장 높았고, 충주시, 보은군, 영동군, 진천군과 괴산군이 80% 이상, 청주시, 음성군, 증평군이 70% 이상으로 높은 수준이었다. 발생면적은 청주시가 6,957 ha로 가장 많았고, 충주시, 진천군, 보은군, 음성군의 순으로 높았다. 초종별 제초제 저항성 비율과 면적은 물달개비 49%, 17,646 ha, 강피 44%, 15,617 ha, 올챙이고랭이 29%, 10,377 ha의 순으로 발생하였다. 충북지역 모든 지역에서 물달개비와 강피는 acetolactate synthase (ALS) 저해제 제초제에 저항성이 40% 이상이므로 집중적인 관리가 필요하며, 현재 설포닐우레아계 제초제 사용이 증가하고 있고, 대부분의 농가가 이앙 후 10일 이전에 제초제를 사용하기 때문에 이앙 후에도 관리가 필요하며, 매년 적용 제초제를 교호 살포하는 방법으로 제초제 저항성 잡초의 발생을 줄여야 하겠다. This study was conducted to investigate the occurrence of an acetolactate synthase (ALS) inhibiting herbicide resistant weed on paddy at 289 sites by soil sampling in Chungcheongbuk-Do of Republic of Korea from February to April in 2017. The most dominant weed was Monochoria vaginalis and Echinochloa oryzicola on each city and county. ALS inhibiting herbicide resistant ratio and occurrence area were 80.6% and 28,272 ha, respectively, in Chungcheongbuk-Do which was 3 times than in 5 years ago. The herbicide resistant ratio, Okcheon-Gun was the highest at 93.8%, Chungju-Si, Boeun-Gun, Yeongdong-Gun, Jincheon-Gun and Geosan-Gun were over 80%, Cheongju-Si, Eumseong-Gun and Jeungpyeong-Gun were over 70%. The herbicide resistant area, Cheongju-Si had the largest at 6,957 ha, Chungju-Si was 4,277 ha, Jincheon-Gun and Boeun-Gun was 3,536 ha and 3,282 ha, respectively. By weed, ALS inhibiting herbicide resistant ratio and occurrence area, Monochoria vaginalis was 49%, 17,646 ha, Echinochloa oryzicola 44%, 15,617 ha, Schoenoplectiella juncoides 29%, 10,377 ha, respectively. In all cities and counties of Chungcheongbuk-Do, Monochoria vaginalis and Echinochloa oryzicola are more than 40% resistant to ALS inhibiting herbicides, intensive management is required. The use of sulfonylurea herbicides is increasing, most farmers use herbicides 10 days after transplanting, so management after transplanting is necessary and the occurrence of herbicide resistant weeds should be reduced by alternating herbicide application every year.

충북지역 쌀가루용 벼 품종의 이앙시기가 생육, 수량 및 수발아 발생에 미치는 영향

이채영,최예슬,이희두,정택구,김익제,김정곤,우선희,Lee, Chae-Young,Choi, Ye-Seul,Lee, Hee-Du,Jeong, Taek-Gu,Kim, Ik-Jei,Kim, Chung-Kon,Woo, Sun-Hee 한국작물학회 2020 한국작물학회지 Vol.65 No.4

Rice consumption in Korea has been decreasing as the eating habits of the Korean people have diversified with rapid economic growth. Recently, floury endosperm rice cultivars were developed to boost rice consumption and replace wheat flour consumption with rice flour, which is vulnerable to viviparity under wet weather during the grain-filling stage because of its loosely packed starch granule structures. To overcome this limitation, it is necessary to find a suitable rice transplanting date to produce high-quality rice flour by altering the heading ecology type and changing the cultivation time by region. We examined four floury endosperm rice cultivars (FERC) in the Cheongju (central plain area) and Boeun (mid-mountainous area) regions of Korea from 2017 to 2019. Of the FERCs, the mid-late maturing types (MMT) Seolgaeng (SG), Hangaru (HGR), and Shingil (SGL) exhibited high yield and yield components after transplanting May 30 in both regions; the early maturing type (EMT) Garumi 2 (GRM2) also exhibited high yield after transplanting June 20 in Cheongju. In addition, MMTs showed the same tendency as the characteristics shown in Cheongju when grown in the Boeun region, and EMT displayed high yield and yield components after transplanting June 10. The FERCs could easily present pre-harvest sprouting in the rainy season during the grain-filling stage after 20 days post-heading because the mean temperature and frequency of more three-day rainfalls have increased over the last 5 years from the previous annual averages. Viviparity of HGR and GRM2 decreased as the transplanting date was delayed, with decreases of 2.3%-4.6% in HGR and 11.9%-23.1% in GRM2 according to the region. SGL was generally resistant to viviparity because of the Tongil type. To minimize pre-harvest sprouting and produce high yield of rice flour in the Chungbuk province, the most suitable transplanting time was the end of May in MMT and the middle and end of June in EMT.

온도에 따른 암모니아 용액에 의한 CO₂ 포집 반응의 변화 양상

김수연,최예슬,김동수,Kim, Soo-Yeon,Choi, Ye-Seul,Kim, Dong-Su 한국물환경학회 2011 한국물환경학회지 Vol.27 No.6

The features of the capture reaction of $CO_2$ by ammonia solution have been investigated along with the effect of temperature on the reaction based upon computer program-utilizing calculation and thermodynamic estimation. The stable region of $CO{_3}^{2-}$ was observed to increase with temperature and the change of the stable region of $CO{_3}^{2-}$ with temperature was greater than the temperature variation of the stable region of other carbonate species. The distribution diagram for $NH_4{^+}-NH_3$ system was constructed and the rise of temperature resulted in the decrease of the stability of $NH_4{^+}$ ion, which was thought to be due to the endothermic nature of its acidic dissociation. Considering the introduction of $Ca^{2+}$ ion in the carbon capture reaction by $NH_4{^+}$, the temperature was observed to be important in the determination of the order of reaction between carbonate ion and these cations. The removal process of $CO_2$ gas by ammonia solution was presumed to occur in open system and the temperature variations of the concentration of carbonate system species along with their total concentration were calculated for the proper control and design of the real process.

충북지역 중북부 중산간지 벼 출수생태형별 적응성 검토

이채영,최예슬,이정관,김익제,강신구,우선희,김영호,Lee, Chae Young,Choi, Ye Seul,Lee, Joung Kwan,Kim, Ik Jei,Kang, Shin Gu,Woo, Sun Hee,Kim, Young Ho 한국작물학회 2021 한국작물학회지 Vol.66 No.3

최근 지구온난화에 의해 기온이 상승하여 조생종을 주로 재배하는 중북부중산간지대에 중생종과 중만생종의 적응성을 검토하기 위해서 출수생태형별로 이앙시기를 달리해서 조생종 오대, 중생종 청품, 중만생종 삼광을 제천의 농가포장에서 시험한 결과는 다음과 같다. 1. 벼 생육에 영향을 미치는 기상요소 중 평균기온은 2010년대에 8월까지는 가장 높았고, 다른 시기보다 월별로 0.7~0.9℃가 높았으며, 일조시간은 장마, 태풍 등으로 인한 기상이변으로 가장 낮은 수준이었다. 2. 지난 35년간 오대의 지역적응시험 결과 출수기는 점점 빨라지고 있으며, 이앙부터 출수기까지 재배일수가 짧아져 간장과 수수가 감소되었다. 과거보다 등숙률은 최대 10%, 천립중은 2 g 이상 증가되었으나, 품질과 직결되는 출수 후 40일간 평균기온은 많게는 2℃ 이상 증가되었다. 3. 제천지역 안전출수한계기는 출수 후 40일간 적산온도 880℃ 기준으로는 8월 11일, 840℃ 기준으로는 8월 15일로 분석되었다. 4. 이앙시기별 출수생태형에 따라 생육은 비슷하였으나 이앙시기별 최고, 최저 수준을 비교한 등숙률은 조생종 6.5%, 중생종 3.7%, 중만생종 2.5% 높았다. 쌀수량은 조생종 83 kg, 중생종 113 kg, 중만생종 47 kg 많았으며, 완전미율은 조생종 17.8%, 중생종 3.2%, 중만생종 5.0% 높았다. 5. 중북부중산간지에서 안전출수한계기 및 완전미수량을 고려한 이앙시기는 조생종은 6월 15일, 중생종은 6월 5일, 중만생종은 5월 25일이었으며, 본 시험 지역(IV-1)에서도 온난화로 인해 중생종과 중만생종이 안정적으로 재배될 수 있을 것으로 예상된다. In recent years, air temperature has been increasing rapidly compared to the 1980s because of global warming. This increase in temperature reduces the yield and quality of rice; therefore, measures are needed to prevent such effects and ensure food security. The early maturing type (EMT) of rice is mainly cultivated in the central northern mid-mountainous area (CNMA). This study was conducted to shift the transplanting date of EMT and to examine the adaptability of the mid-maturing type (MMT) or mid-late maturing type (MLMT) in the Jecheon region of the CNMA to address global warming. The air temperature increased by 0.7-0.9℃ in the 2010s, compared to that in the 1980s, and was similar to other decades during the ripening period. Over the past 35 years, considering rice quality, the heading date of the Odae variety has arrived sooner by approximately 10 days, the ripened grain ratio has increased by more than 10%, and the thousand grain weight; however, the mean temperature at 40 days after heading has increased by more than 2℃. The late marginal heading date in the Jecheon region was determined as August 11 based on the accumulated temperature of 880℃ and August 15 based on 840℃ for 40 days after heading. According to different transplanting dates, milled rice yield per 10 a was the highest at 567 kg with June 10 in EMT, 595 kg with June 10 in MMT, and 572 kg with May 30 in MLMT. Considering the late marginal heading date, rice yield, and quality, the optimum transplanting date was June 15 in EMT, June 5 in MMT, and May 30 in MLMT in the Jecheon region of CNMA. Owing to global warming, MMT and MLMT are expected to be reliably cultivated in the CNMA.
