강현경,정근,Kang, Hyun-Kyung,Chung, Keun 한국응용곤충학회 2010 한국응용곤충학회지 Vol.49 No.4

논의 생물다양성에 관한 관심이 증가하면서 논 먹이망의 중요한 부분을 차지하고 있는 수서성 대형무척추동물을 정량적으로 평가하기 위한 효율적인 방법이 요구된다. 이를 위해, 강원도 춘천시와 충청남도 홍성군에 위치한 논에서 채집망과 방형구, 피이프형 채집기(core)로 얻어진 자료를 비교하여 적절한 채집기를 알아보았다. 채집망은 틀이 사각형이고, 바닥이 평평하기 때문에, 채집망의 조사 면적은 토양을 훑은 길이와 망의 넓이를 곱하여 측정되었다. 모든 채집물은 두 벼줄 사이에서 채집되었다. 대형무척추동물은 춘천과 홍성에서 24, 28분류군이 채집되었다. 춘천에서 분류군수는 세 가지 채집기에서 유사했지만(17-18분류군), 추정밀도는 그렇지 않았다(채집망, $1317/m^2$; 방형구, $1368/m^2$ core, $1810/m^2$). 홍성에서는 채집망에서 분류군 수가 가장 컸었지만(채집망 25분류군; 방형구, 21분류군 core, 16분류군), 추정밀도는 core에서 가장 높았다(채집망, $1586/m^2$; 방형구; $2595/m^2$; core $3704/m^2$). 각 채집기의 효율은 분류군에 따라 달랐는데, 채집망에는 주로 수서곤충류가 많았던 것에 비해 방형구에는 빈모류나 깔따구과 등 토양 속에 서식하는 종류에 대한 효율이 높았다. 논에 서식하는 수서곤충에 대한 정량자료와 희귀분류군에 대한 정성자료를 통시에 얻고자 하는 경우에는 채집망을 이용하여 논 가장자리와 논 내부에서 각 6회 정량채집하고, 논둑 근처와 논 가운데에서 정성채집을 수행되는 것이 시간 및 노동력 측면에서 가장 경제적 이라고 생각된다. With growing interest in biodiversity in rice paddies, efficient sampling methods for quantitative evaluation of aquatic macroinvertebrates are needed because of their important role in rice paddies' food webs. For this reason, we sought a proper sampling method through comparing data collected by using aquatic net, quadrat, and core in rice paddies located in Chuncheon-si, Kangwon-do, Hongseong-gun, and Chungcheongnam-do. Because the frame of the net was rectangular and had a flat bottom, the area, sampledwith the aquatic net, was calculated by multiplying the net width by the sweeping length, All samples were taken from the space between the rows of rice plants. Twenty four taxa of macro invertebrates were collected in Chuncheon and 28 taxa in Hongseong. In Chuncheon, the number of taxa was similar among three sampling methods (17-18 taxa), but the number of individuals was different (aquatic net, $1,317/m^2$; quadrat, $1,368/m^2$; core, $1,810/m^2$. In Hongseong, the number of taxa sampled by aquatic net was the highest (aquatic net, 25 taxa; quadrat, 21 taxa; core, 16 taxa), but the core was the highest in the number of individuals (aquatic net, $1,586/m^2$; quadrat, $2,595/m^2$; core, $3,704/m^2$. The efficiency of samplers differed among taxa. Most of aquatic insect taxa were more abundant in the aquatic net, while those living on or in the paddy substratum such as Oligochaeta and Chironomidae were collected more in the quadrat sampler. To collect quantitative data for aquatic insects as well as to produce inventory of rare taxa, we suggest, based on samplers used in this study, to take quantitative samples of 6 replications from each of the edge and inner zones of a rice paddy by using an aquatic net, and to take qualitative samples both from sides of levees and the inner zone of rice paddy by using an aquatic net.

This study was conducted to formulate management guidelines for monumental old trees in Korea through analysis of growing environments. A total of 20 old trees designated as natural monuments in Seoul, Incheon, and Gyeonggi provinces were surveyed for biological characteristics, surrounding environments, root collar conditions, tree health, and soil characteristics. Relationships among root collar conditions, tree health, and soil characteristics were analyzed by correlation. The old solitary trees designated as natural monuments included Pinus bungeana(4 trees), Juniperus chinensis(3 trees), Ginkgo biloba(3 trees), Poncirus trifoliata(2 trees), Actinidia arguta, Wisteria floribunda, Thuja orientalis, Quercus variabilis, Sophora japonica, Fraxinus rhynchophylla, Zelkova serrata, and Pinus densiflora. The tree height ranged from 3.56 to 67m, and root collar diameter ranged from 1.01 to 15.2m. The monumental old trees were growing on the various sites ranging from gardens, historical sites, open agricultural fields, mountain hills, to near the ocean beaches and streams. The coverage of bald land ranged from 50 to 100%, and depth of filled soil around the root collar ranged from 0 to 50cm. Tree health was expressed as the amount of branch dieback, cavity development, detachment of cambial tissue, infliction by diseases and insects. The branch dieback ranged from 5 to 20%, cavity development ranged from 10 to 100$cm^3$, detachment of cambial tissue ranged from 5 to 45%, and infliction by diseases and insects ranged from 5 to 20%. Soil pH ranged from 5.9 to 8.3, organic matter contents from 12 to 56%, phosphorus contents from 104 to 618ppm, while soil compaction ranged from 7 to 28mm. Results of correlation analysis showed that coverage of bald land was the most serious factor to deteriorate the cavity development and detachment of cambial tissue. In addition, chemical properties of soils seemed to be related to the health of the trees.

일부 제조업 근로자들의 구강건강실천과 치아우식 위험도의 관련성에대한 융합적 평가 -CRT^® bacteria를 이용하여

강현경,허성은,Kang, Hyun-Kyung,Heo, Seong-Eun 한국융합학회 2015 한국융합학회논문지 Vol.6 No.6

본 연구는 제조업근로자의 근무특성 및 구강건강실천정도를 조사하여 치아 우식증 위험도에 미치는 요인을 파악하고 근로자들의 구강건강 증진을 위한 프로그램 개발에 필요한 기초자료를 제공하고자 한다. 연구방법은 2014년 7월1일부터~8월1일까지 부산 경남지역 일부 제조업 근로자를 대상으로 자기기입식 설문조사 및 타액 내 미생물에 의한 치아우식발생요인검사(S.mutans검사, Lactobacillus검사)를 실시하여 다음과 같은 결과을 얻었다. 하루 평균 근무시간 10시간 이상이 10시간미만일 경우보다 치아우식위험도가 높았고, 흡연자의 경우 비흡연자보다 치아우식위험도가 높았으며, 잇솔질 습관이 1점 증가함에 따라 치아 우식증 발생 고위험군일 확률이 S.mutans검사에서 0.044배 낮고, Lactobacillus검사에서 0.004배 낮았다. 따라서 제조업근로자들의 근무환경 개선을 위한 제도적인 노력과 지속적인 구강보건교육 및 실천이 이루어질 수 있는 사업장 구강보건교육을 위한 조직적인 노력이 필요할 것으로 판단된다. In this study, the characteristics and oral health status of manufacturing workers were investigated to confirm the factors affecting their risk of developing dental caries and to prepare basic data for developing oral health promotion programs for such workers. A self-administered questionnaire survey and saliva microorganism examinations (S. mutans and Lactobacillus tests) were conducted from July 1 to August 1, 2014 targeting the manufacturing workers in the Busan and Gyungnam areas, to confirm the factors affecting dental caries development among manufacturing workers. As a result, the risk of dental caries was found to be higher in the workers who worked for 10 hours or longer a day than in those who worked for less than 10 hours a day, and in the smokers than in the non-smokers. A 1-point increase in the brushing pattern score resulted in 0.044 times less risk of dental caries development in the S. mutans test and 0.004 times less risk in the Lactobacillus test Therefore, systematic support is needed to improve the work environment of manufacturing workers, along with continuous oral health education in workplaces.

This study was conducted to narrow the view on this by analyzing the difference between dental hygienists and patients' cognition and oral health education of scaling. The study was total 202 people were finally analyzed. The method of analysis compared the cognition of scaling and oral health education, and a hierarchical regression analysis was conducted to check the effect of cognition and oral health education on dental selection by stages. As a result, there were significant differences in all but one of the nine items of cognition for scaling (p<0.01) and significant differences appeared in all but seven of the 19 categories of oral health education for scaling (p<0.01). Therefore, dental hygienists will have to seek ways to reduce these differences and continue to study how to explain them in scaling so that they can have a positive impact on patients' dental clinic choices. 본 연구는 치과위생사와 환자의 치석제거에 대한 인식과 구강보건교육의 차이를 분석하여 이에 대한 견해를 좁히기 위해 실시되었다. 본 연구에는 총 202명을 대상으로 최종 분석하였다. 분석방법으로 치석제거에 대한 인식과 구강보건교육을 비교하였고, 치석제거 인식과 구강보건교육이 치석제거로 인한 치과선택에 미치는 영향을 단계별로 확인하기 위해 다중회귀분석을 시행하였다. 그 결과 치석제거에 대한 인식 9개 항목 중 1개의 항목을 제외한 모든 항목에서 유의한 차이가 나타났고(p<0.01), 치석제거에 대한 구강보건교육 19개의 항목 중 7개의 항목을 제외하고 모든 항목에서 유의한 차이가 나타났다(p<0.01). 따라서 치과위생사는 이러한 차이점을 줄일 수 있는 방안을 모색해야 할 것이며, 환자의 치과선택에 긍정적인 영향을 줄 수 있도록 치석제거 시 설명하는 방법에 대한 지속적인 연구를 해야 할 것이다.

This study was conducted to analyze the planting structure and ecological characteristics of greon spaces on the grounds of e Dangjin steam power plant. To achieve these goals, we surveyed existing vegetation, plant community structure, Plant volume and growth rate. Based on e vegetation analysis, existing vegetation was classified into six types: herbaceous species $(70.54\%)$, evergreen coniferous trees $(21.17\%)$, deciduous broad-leaved trees $(5.10\%)$, deciduous coniferous trees $(1.47\%)$, shrubs $(0.12\%)$, and other types $(1.59\%)$. The coal storage, office, and playground areas were community is the natural forest area where a Pinus thunbergii / Pinus densiflora community is distributed in terms of vegetation structure, species diversity, plant volume, and growth rate. The artificial green spaces(near the coal storage, office, playground areas) had a single-layer structure. Species diversity indices of the artificial green areas were $0.1655\~0.4807$ compared to 0.8628 in the natural forest, which presented a good growth environment. Also, the plant volume in the artificial green space was lower than that of the natural green space. Therefore, it would be desirable to develope a multi-layer structure similar to that of the vegetation in the natural green space in order to improve the amount of plant volume. The plant-damage ratio of Pinus thunbergii was $52.48\%$ in the coal storage area, and $8.48\~ 11.52\%$, in the other survey areas. Also, the vitality of Pinus thunbergii was $15.45k{\Omega}$ in the coal storage areas, which indicates bad growing conditions. This suggests that soil characteristics and dust have a bad impact on growth. The investigation into deciduous tres' growth status showed that appropriate plants would be Albizzia julibrissin, Acer palmatum var. sanguineum, Acer palmatum, Malus spp., Prunus sargentii.

유아기 자녀의 위험감수형 놀이에 대한 부모의 태도 및 인식

강현경(Kang, Hyun Kyung),김갑순(Kim, Kab Soon) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.1

본 연구의 목적은 유아의 위험감수형 놀이에 대한 부모의 태도 및 인식을 알아보는 것이다. 이를 위해 문헌연구를 통한 설문지를 제작하고 공동연구자와 유아교육전 문가, 유치원 원장과의 내용타당도 과정을 거치고 예비검사를 수행하였다. 이후 최종 수정된 설문지로 2017년 8월부터 한 달간 서울, 경기도 지역의 유치원과 어린이집 만 4-5세 유아 236명의 부모를 대상으로 설문조사를 실시하였다. 수집된 자료를 빈도분석과 t검증을 통해 분석함으로써 다음과 같은 연구결과를 얻었다. 첫째, 부모 들은 자녀의 위험감수형 놀이에 대해 대체로 허용해주는 태도를 취하고 있었고, 자녀에게 안전을 지도하는 것이 가장 바람직한 지도방안이라고 인식하고 있었다. 둘째, 위험감수형 놀이의 6가지 유형 중 부모 ‘미로와 같이 유아가 길을 잃거나 사라질 수있는 놀이’유형에 대해서 가장 허용하지 못하였다. 한편, 성별, 연령에 따른 차이검증을 실시한 결과 ‘미로와 같이 유아가 길을 잃거나 사라질 수 있는 놀이’ 요인의 ‘시야 에서 벗어나 놀기’ 항목에서만 연령별, 성별 차이를 보이고 있었다. 셋째, 부모는 안전과 위험감수형 놀이 중 안전을 더 중요하게 인식하고 있었다. 이는 부모가 위험감 수형 놀이를 허용함에 있어 다소 혼돈스럽고 일관되지 못한 태도를 취하고 있음을 의미한다. This study was to find out parents’ perception about young children’s risk-taking play. Two hundred and thirty six parents with young children aged 4 to 5 in Seoul and Gyeonggi-do participated in this study, and the data from them were analyzed by frequency analysis and t-test. The results were as follows: first, many parents considered that risk-taking play was acceptable, and safety guidance was the most desirable way for the play. Second, among the six risk-taking play types, ‘play where the children can disappear/get lost’ was the least acceptable type. And, at the difference analysis of sex and age, there was the relevant difference at the only item, ‘disappearing from the parent’s monitoring.’ Third, parents perceived safety was more important than the risk-taking play.

劉向 ≪列女傳≫의 소설적 색채와 표현

姜賢敬(Kang, Hyun-kyung) 동아인문학회 2014 동아인문학 Vol.27 No.-

西漢시대 劉向(B.C. 79∼B.C. 8)이 편찬한 ≪列女傳≫은 女誡書의 典範으로서 뿐만 아니라, 여성학의 관점에서 혹은 여성교육사의 영역에서 지속적으로 검토되고 있으며, 또한 중국소설발전상 초기 형태의 작품으로서 인정받기도 하였다. 본고에서는 ≪列女傳≫ 전반에 걸쳐 소설기법으로 생동감 넘치게 묘사된 傳記文이 적지 않다고 판단하고, 入傳된 인물의 등장과 사건, 줄거리 전반에 걸쳐서 소설적인 표현기법과 그 특징을 중점적으로 살펴보고자 하였다. ≪列女傳≫은 전기문의 기록 형태를 지녔으면서도 다양한 소설적 색채로써 작자의 편찬 의도와 주제를 잘 드러내었다고 본다. 작자는 전반적으로 여성 주인공과 대립인물 (대부분 남성)을 설정하여 주인공이 보여준 인생관?윤리관?정치관 등을 강조하였고, 대화로 연철된 사건?상황의 전개를 통하여 입체감 있는 줄거리를 구성하였다. 또한 몇몇 전기문에서는 해학적 희극적인 요소라든지, 감동의 장면을 더하여 독자의 관심과 흥미를 일으키는 표현기법을 보여주기도 하였다. 따라서 ≪列女傳≫이 중국소설의 발전상 초기 단계에 속한 것이라서 의도적인 소설기법을 충분히 운용하였다고 볼 수 없어도, 후대의 본격적인 소설 양상과 비교해서 큰 손색이 없는 정도의 독특한 소설적 표현을 지녔다고 평가해도 될 것이다. ≪LieNuZhuan≫(列女傳) published by Liu Xiang (B.C. 79∼B.C. 8) during the Han dynasty in China has achieved a great deal of recognition as a guideline of discipline of women in traditional society. Recently, it has been continuously reviewed in the aspect of women studies or in the history of education for women, and acknowledged as an early literary work in the Chinese novel development phase. In this article, we mainly investigated the main characters (heroines) and events contained in the book, novelistic expressive techniques through the plot and the features after we decided that there are a number of biographical literatures described lively with novelistic expressive techniques throughout ≪LieNuZhuan≫ ≪LieNuZhuan≫ has not only a written form of biographical literature, but also diverse novelistic colors to demonstrate the author"s compilation intention and topic. The author generally set a heroine and a conflicting character (mostly men) to emphasize a view of life-ethical belief-a political view of a main character and constructed the stereoscopic plot through development of events and situations with various dialogue. In addition, humorous and comedic factors, as well as touching scenes used as expressive techniques, were given to several biographical literatures to arouse the attention and interest of readers. Therefore, although ≪LieNuZhuan≫ might not fully manage the intentional novelistic techniques because it is included in an early stage of Chinese novel development, and it is still determined that the novel has unique novelistic expressions comparable to the later full-scale novel concept.

This study evaluated 23 botanic gardens and arboretums under two main categories including professional group and operational group. As for professional group, the main difference between the functions of botanic gardens and arboretums was analyzed. In the case of operational group compared professional group respectively, on categories including importance of function and implementation, seeking to provide fundamental data of botanic gardens and arboretums by enhancing the quality of visitors and examining functional differences. The result of a difference in arboretums` function between professional and operational groups, the study analyzed the importance of botanic gardens and arboretums in terms of detailed categories such as research, education, collection, display, retention, and service for visitors. As a result, professional group showed retention 4.32>education 4.11>research 4.09>service for visitors 4.05, and operational group showed retention 3.70>service 3.52>education 3.41>research 3.37, indicating that both groups had retention as the most selected answer. Looking closely at the functions of the currently implemented detailed categories of botanic gardens and arboretums, such as research, education, collection, display, retention, and service for visitors, the study showed that 91.3% selected rare species and individual multiplication for research function, 78.3% chose education of natural ecosystem for children for education, 73.9% answered space for experiencing nature for display, and 73.9% also replied managon, diof rare species, reproduction, and retention of native plants` species for retention category, and service for visitors showed 95.7% for implementation. The study could not clearly point out the influence between predictors due to absence of an established comprehensive evaluation model. Also, it analyzed and reviewed comparison of functions of professional group and operational group, but in the future, it should conduct study on a systemic and objective classification of botanic gardens and arboretums to clearly examine the difference in views between groups, which also requires, at the same time, study on management policy of botanic gardens and arboretums or suggesting guidelines that suit types of forms, and also study on facilities and program development that can be applied to each class.
