장정희,서종진,Jang, Cheong Hee,Seo, Jong Jin 한국학교수학회 2021 韓國學校數學會論文集 Vol.24 No.3

과거에서 현재까지 교양 수학 수업에서 교육 환경의 변화를 추구하였으나 현재에도 대학 교육 여건으로 말미암아 일반강의식 수업이 이루어지고 있다. 이에 본 연구에서는 일반강의식 수업에서 학생들에게 도움이 되는 교수·학습 방법을 찾고자 하였다. 개별 과제와 피드백 및 수업 내용을 필기하는 방법이 동일 과제와 피드백을 제공하는 방법이나 동일 과제와 피드백 제공 및 수업 내용을 필기하도록 하는 방법보다는 학생들의 학습에 도움이 되는 것으로 나타났다. From the past to the present, general mathematics classes have pursued changes in the educational environment. However, due to the actual college education conditions, general lecture classes are taking place. In this study, we wanted to find teaching and learning methods that would help students in general lecture classes. As a result, one group that took notes about class content and provided feedback on individual tasks was more effective in math achievement than the group that provided feedback on the same task. In addition, one group who took notes on class content and provided feedback on individual assignments was more effective in math achievement than the group who took notes on class content and provided feedback on the same task.

‘Jungdream’ is an early maturing, high-quality rice cultivar developed in 2017 by the crop breeding team at Crop Research Division,GARES, Hwaseong, Korea. ‘Jungdream’ was first developed in 2008 from crossing a medium-late maturity cultivar ‘Chilbo’ and an early maturitycultivar ‘Ungwang’. The heading date of this cultivar is July 28thin the Gyeonggido Province. Its culm length is 63 cm, and it has 19 paniclesper hill and 82 spikelets per panicle. It is a medium-small grain brown rice cultivar with a 1000-grain weight of 20.6 g. Its cold toleranceis lower than that of ‘Hwaseong’, which is the standard cultivar in the central region, as is its degree of lodging tolerance. ‘Jungdream’ isresistant to rice blast and stripe virus diseases but is susceptible to bacterial leaf blight and other viral diseases and pests. The appearance ofmilled ‘Jungdream’ rice is clear, and its amylose content is 16.5%, which is lower than that of ‘Hwaseong’. The palatability of cooked ‘Jungdream’rice is better than that of ‘Chucheong’, which is the main cultivated crop in Gyeonggido. Its milling ratio is 75.0%, which is lower than thatof ‘Hwaseong’. The yield of milled ‘Jungdream’ rice was 5.42 MT/ha in the local adaptability tests during standard cultivation in four regionsfrom 2015 to 2017. ‘Jungdream’ is highly adaptable to the environmental conditions in the Gyeonggido Province (Registration No. 8236).

근대 조선의 『한네레의 승천』 수용과 방정환

장정희 ( Jung Hee Jang ),박종진 ( Jong Jin Park ) 건국대학교 동화와번역연구소 2015 동화와 번역 Vol.30 No.-

본고는 근대 아동문학과 한네레의 승천 전유 양상에 대해 논의하였다. 방정환은 독일 자연주의 작가 하우프트만의 한네레의 승천 을 번역, 『사랑의선물』(개벽사, 1922) 5번째 이야기로 수록하였다. 그런데 번역동화의 제목을 한네레의 죽음 이라고 명명한다. 방정환은 『어린이』잡지 창간호에 동화극 노래주머니 를 발표하기에 앞서, 이미 외국의 유명 동화극 한네레의 죽음 을 ‘천도교 동화극대회’(1923. 1. 14) 때상연하였다. 이 동화극은 아동 학대와 인권 옹호에 대한 사회적 경종을 촉구한 근대 아동문학사 최초 동화극 상연으로서 의의가 크다. 방정환은 하우푸트만 원작 한네레의 승천을 조선의 현실과 어린이 독자의 수준에 맞게 개작하여 제목도 한네레의 죽음으로 달았다. 한네레의 죽음 은『사랑의 선물』에 수록된 10편 가운데 가장 변개가 많은 작품이다. 따라서 본고는 그 개작 양상에 주목하여 한네레의 죽음 이 어떻게 ‘승천’의 서사를 ‘죽음’의 서사로 전유해 가는지 분석하였다. 본고는 크게 그 변개 양상을 ‘등장 인물 구성의 차이’, ‘한네레 가출의 설득력 있는 상황 묘사’, ‘계부 마테른의 징벌 서사 약화’, ‘기독교적 내세 천국관의 삭제’ 등 4가지로 분석하였다. 무엇보다 한네레의 죽음 에서 가장 ‘방정환다운’ 서사로 피력되는 독자성은 ‘한네레와 그 언니’, ‘두 자매의 죽음’ 서사이다. 방정환은 원작에 존재하지 않는 제3의 인물인 ‘한네레의 언니’를 등장시켜 조선의 핍박받고 고통스러워하는 어린이의 모습을 대변하는 역할을 부여한 것이다. 본고는 두 어린 자매는 비록 원작에서와 같이 천국 세계의 ‘성녀’가 되지는 않지만, 조선 어린이의 희생과 고통을 대속하는 구원자로서 더 큰 의미의 대승적 ‘신성’을 완성하였다고 해석하였다. 『사랑의 선물』은 1920년대 한국 동화문학 형성기를 해명하는 중요한 사료이다. 앞으로 보다 진전된 연구가 이루어져야 할 것으로 본다. This study discusses about aspects of appropriation of the ascension of Hanneles and modern children``s literature. Bang Jung Hwan translated the Germany naturalistic writer, Gerhart Hauptmann``s the ascension of Hanneles and published it as the fifth story in 『Gift of Love』 (Gae-byuk-sa 1922). But he named the title of the translated fairy tale Death of Hanneles . Bang Jung Hwan already put on the famous foreign play for children, Death of Hanneles in ``the Cheondogyo meeting for plays for children…(1923. 1. 14), before he published the play for children, a pocket of songs in the first issue of the magazine 『Children』. This play for children was of great significance as the first performed play for children in the modern history of children literature, as it called the social alarm for child abuse and the protection of human rights on stage. Bang Jung Hwan adapted the Hauptmann``s original work, the ascension of Hanneles , so close to children reader``s levels and the reality of the Joseon dynasty. He also named the title of it Death of Hanneles . Death of Hanneles was the biggest work of changes in the ten stories which were contained in 『Gift of Love』. Therefore this study pays attention to the adaption aspects of it and analyzes how 『Death of Hanneles』 changed the narrative of ‘the ascension’ to the narrative of ‘death’ and appropriated it. This study analyzes the change aspects as ‘differences in character composition’, ‘persuasive description of circumstances of Han-na-re``s runaway’, ‘the narrative weakness for her stepfather, Matereun``s punishment’, and ‘the deletion of the view of christian afterlife heaven’ in a big category. Most of all, the originality that was expressed as the most ‘like Bang Jung Hwan’ narrative in 『Death of Hanneles』 is the narrative of ‘Hanneles and her older sister’ and ‘Death of two sisters’. Bang Jung Hwan presented the third person, ‘the older sister of Hanneles’ who did not appear in the original work and gave her a role to speak for the child who was persecuted and felt pain in the Joseon society. The two little sisters completed the broader ‘divine nature’ of the bigger meaning as saviors who went through sacrifice and pain instead of children of the Joseon dynasty, although they did not come to be ‘saintess’ of the heaven world like in the original work.

본 연구는 MAIS 실행성과에 영향을 미치는 영향요인들간의 상호관련성을 고려하면서 영향요인들의 실행성과에 대한 직접 또는 간접적인 영향을 실증분석하여 실행성과를 높일 수 있는 방안들을 제시하고자 수행되었다. 연구 수행결과, 업무 난이도/다양도는 MAIS 만족도 및 이용도와 유의적인 음의 상관관계를 가지거나 관련성이 없는 것으로 나타났다. 그리고 업무 난이도와 촉진요인들간에는 유의적인 음의 상관관계가 있는 것으로 나타났고 업무 다양도는 시스템개발 참여와만 유의적인 양의 상관관계를 보여 가설과는 상반되는 결과들이 나타났다. 업무 난이도/다양도는 촉진요인들을 통해 실행성과에 간접적인 영향을 미치는 것으로 나타났으며, 촉진요인들과 실행성과간의 관계를 분석한 결과 전산 부서의 기술적 능력을 제외하고 모두 유의적인 양의 상관관계를 가지는 것으로 나타났다. 그리고 조직크기는 부분적으로 조절영향을 미치는 것으로 나타났지만 전산화 수준은 거의 조절영향이 없는 것으로 제시되었다. 본 연구에서는 분석결과들에 근거하여 우리나라 MAIS 실행성과를 제고시키는 방안들을 제시하였다. This study empirically examined the direct and indirect relationships among influence factors and the performance of management accounting information systems (MAIS). The empirical results show that the task difficulty and variety have the negative or no relation with the performance. Task difficulty is also negatively related with the facilitating factors, and task variety has the positive relation with only the user participation. These results are opposite to the proposed hypotheses. It is empirically proved that the task difficulty and variety have the indirect impacts on the MAIS performance through the facilitating factors. Except for the technical capability of information system(IS) personnel. there are also the positive relationships between MAIS performance and facilitating factors. The moderating effects of the organization size and IS maturity are inconclusive. Based on the results of this study, we suggest the practical ways to improve the MAIS performance.

Pesticides are extensively used for the control of crop pests in agriculture and forestry. Organophosphate (OP) and carbamate pesticides are especially effective for the control of a variety of harmful insects. However, these cholinesterase inhibitors are also dangerous to non-target organisms (wildlife and other animals) because of their high acute toxicity. Most poisonings by pesticides occur as a result of misuse or accidental exposure, but intentional killing of unwanted animals also occurs. At the request of a local autonomous entity, we investigated wild bird poisonings by pesticides from 2003 to 2007. The 207 suspicious samples of pesticide poisoning based on the necropsy were analyzed by GC/NPD, GC/FPD, or GC/MSD. We looked for trends in the identification of pesticides in wild birds thought to have died from poisoning. Pesticides were determined in 59% of the total samples analyzed. Phosphamidon and monochrotophos were the most common pesticides identified, which amounted to 77% of the subtotal. Other OP and carbamate pesticides were also found in various concentrations from dead wild birds. The determined rates of pesticides were as high as 86% and 76% in 2003 and 2006, respectively, during an outbreak of avian influenza in Korea.

Objectives : The aim of this study is to examine the neuroprotective effect of wheat bran extract (WBE) against β-amyloid (Aβ)-induced apoptotic cell death in SH-SY5Y human neuroblastoma cells and memory impairment in triple transgenic animal model`s of Alzheimer`s disease (3xTg AD mice). Methods : In SH-SY5Y cells, MTT assay and TUNEL staining were conducted to evaluate the protective effect of WBE against Aβ25-35-induced neurotoxicity and apoptosis. Alterations in mitochondrial transmembrane potential (MMP), expression of proapoptotic Bax and antiapoptotic Bcl-2 proteins, cleavage of PARP, and brain-derived neurotrophic factor (BDNF) levels were analyzed to elucidate the neuroprotective mechanism of WBE. To further investigate the memory enhancing effect of WBE, Morris water maze test was performed in 3xTg AD mice. Results : In SH-SY5Y cells, WBE protected against Aβ25-35.caused cytotoxicity and apoptosis as shown by the restoration of cell viability in MTT assay and inhibition of DNA fragmentation in TUNEL staining. Aβ25-35. induced apoptotic signals such as dissipation of MMP, decreased Bcl-2/Bax ratio, and cleavage of PARP were suppressed by WBE. Moreover, WBE up-regulated the protein levels of BDNF, which seemed to be mediated by activation of cAMP response element-binding protein (CREB). In 3xTg AD mice, oral administration of WBE attenuated learning and memory deficit as verified by reduced mean escape latency in water maze test. Conclusions : WBE protects neuronal cells from Aβ25-35.induced apoptotic cell death and restores learning and memory impairments in 3xTg AD mice. These findings suggest that WBE exhibit neuroprotective potential for the management of AD.

하천 녹조 모니터링을 위한 드론 다중분광영상의 분광지수 적용성 평가

최은영 ( Eunyoung Choe ),정경미 ( Kyung Mi Jung ),윤종수 ( Jong-su Yoon ),장정희 ( Jong Hee Jang ),김미정 ( Mi-jung Kim ),이호중 ( Ho Joong Lee ) 대한원격탐사학회 2021 大韓遠隔探査學會誌 Vol.37 No.3

신속하게 면단위(2-Dimension)로 하천의 녹조 우심지역을 관측하기 위해 드론 다중분광영상을 이용한 분석기법을 연구하였다. 드론은 항공기나 위성에 비해 관측 면적이 작지만 높은 공간해상도와 현장접근 및 데이터 획득 용이성, 대기에 의한 간섭 저감, 다중분광센서를 이용한 신속한 자료처리로 녹조 모니터링 효율성을 향상시킬 수 있을 것으로 보고 있다. 이러한 드론의 다중분광센서 영상으로 하천의 녹조발생 현황을 모니터링하기 위해 광합성 색소에 의한 분광특성을 반영하는 분광지수들을 비교 분석하고 Chlorophyll-a(Chl-a) 농도 추정식에 적용 가능성을 평가하였다. 주로 Red-edge 밴드를 포함하는 분광지수가 Chl-a 농도와 높은 상관성을 보였는데, 그 중에서도 3-Band Model(3BM), Normalized Difference Chlorophyll Index(NDCI)가 각각 비슷한 수준으로 가장 높은 통계적 유의성(R²=0.86, RMSE=7.5)을 나타내었다. NDCI의 경우에는 두 개의 분광밴드만 적용되는 간결한 수식과 정규화된(Normalizing) 결과값으로 신속하고 표준화된 프로세싱이 가능할 것으로 보이며 드론 녹조 모니터링에서 적용성이 높을 것으로 기대된다. 3BM의 경우에는 Red-edge 영역에서 두 개의 파장대를 적용해야 하나 본 연구에서 사용한 드론 센서에는 한 개의 Red-edge 밴드만 포함되어서 근적외선으로 대체하여 수식을 적용하였는데 Red-edge 파장영역이 세밀한 분광센서를 활용할 경우에 NDCI 보다 높은 정확도를 나타낼 수 있을 것으로 보인다. Remote sensing techniques using drone-based multispectral image were studied for fast and two-dimensional monitoring of algal blooms in the river. Drone is anticipated to be useful for algal bloom monitoring because of easy access to the field, high spatial resolution, and lowering atmospheric light scattering. In addition, application of multispectral sensors could make image processing and analysis procedures simple, fast, and standardized. Spectral indices derived from the active spectrum of photosynthetic pigments in terrestrial plants and phytoplankton were tested for estimating chlorophyll-a concentrations (Chl-a conc.) from drone-based multispectral image. Spectral indices containing the red-edge band showed high relationships with Chl-a conc. and especially, 3-band model (3BM) and normalized difference chlorophyll index (NDCI) were performed well (R²=0.86, RMSE=7.5). NDCI uses just two spectral bands, red and red-edge, and provides normalized values, so that data processing becomes simple and rapid. The 3BM which was tuned for accurate prediction of Chl-a conc. in productive water bodies adopts originally two spectral bands in the red-edge range, 720 and 760 nm, but here, the near-infrared band replaced the longer red-edge band because the multispectral sensor in this study had only one shorter red-edge band. This index is expected to predict more accurately Chl-a conc. using the sensor specialized with the red-edge range.
