        노인의 지역사회 야간보행시 안전행동에 영향을 미치는 요인

        이성은 한국문화융합학회 2018 문화와 융합 Vol.40 No.6

        The purpose of this study was to examine factors affecting protective behaviors when walking at night among the elderly. This study used data from 2016 Social Survey. A total of 1,829 people aged 65 years or older who answered that they are afraid to walk alone at night in some areas in their neighborhoods were selected for the analyses. To identify sample characteristics, descriptive statistics were used and factors affecting protective behaviors when walking at night were examined using binomial logistic regression analysis. The rate of protective behaviors when walking at night in the study population was 54.8%, which is somewhat low. The possibility of doing protective behaviors when walking at night among the older persons was significantly higher in older, female elderly and rural, apartment residents. These results can be used to suggest plans to prevent crime victimization and increase safe walking at night among the elderly by exploring factors affecting protective behaviors when walking at night in the communities. 본 연구는 노인의 야간보행시 안전행동에 영향을 미치는 요인을 밝히는 것을 목적으로 한다. 이를 위해 2016년 사회조사 데이터를 이용하여 야간보행시 두려움을 느낀다고 응답한 65세 이상 노인 총 1,829명을 대상으로 분석을 실시하였다. 분석방법으로는 연구대상자의 일반적 특성을 파악하기 위한 기술통계분석과 안전행동 영향요인을 파악하기 위한 이항 로지스틱 회귀분석이 사용되었다. 분석결과 노인의 야간보행시 안전행동 수행률은 54.8%로 비교적 낮은 것으로 나타났다. 다음으로 안전행동 영향요인에 있어서는 연령, 성별, 거주지역, 그리고 주거형태가 유의미한 요인으로 나타났다. 보다 구체적으로 연령이 높을수록, 아파트에 거주할수록 노인의 안전행동 가능성이 증가했으며, 남성일 경우와 도시에 거주할 경우 노인의 안전행동 가능성이 감소하는 것으로 나타났다. 본 연구의 결과는 야간보행시 노인의 안전행동에 영향을 미치는 요인을 탐색함으로써 노인의 범죄피해를 예방하고 안전보행을 증진시킬 수 있는 방안을 제시하는데 활용될 수 있다.

        대기오염 인식이 삶의 만족도에 미치는 영향과 녹지환경 만족도의 조절효과

        이성은 한국산림과학회 2019 한국산림과학회지 Vol.108 No.4

        The purpose of this study was to examine the moderating effect of green space satisfaction on the relationship between the perception of air pollution and life satisfaction. To achieve this, the current study employed data from the 2018 Social Survey, and a sample of 37,461 participants was analyzed using moderated multiple regression analysis. Results showed that while greater satisfaction with green spaces improved life satisfaction, a more negative perception of air pollution within the community reduced life satisfaction. It was also found that green space satisfaction moderated the relationship between the perception of air pollution and life satisfaction. In other words, greater satisfaction with green spaces buffered the effect of a negative perception of air pollution on life satisfaction. The results of this study suggest that a green environment should be considered an important resource for preventing reduced life satisfaction, and illustrate that there is a need for developing various strategies for the expansion and improvement of green spaces within communities. 본 연구는 대기오염에 대한 인식과 삶의 만족도의 관계에서 녹지환경 만족도의 조절효과를 검증하는 것을 목적으로 하였다. 이를 위해 2018년 사회조사 자료를 활용하였으며, 조절회귀분석을 이용하여 총 37,461명을 대상으로 분석을 실시하였다. 분석결과 녹지환경에 대한 만족도가 높을수록 삶의 만족도가 증가하였으며, 대기오염에 대한 인식이 부정적일수록 삶의 만족도가 감소하는 것으로 나타났다. 또한 녹지환경에 대한 만족도는 대기오염 인식과 삶의 만족도 사이의 관계를조절하는 것으로 나타났다. 다시 말해, 녹지환경에 대한 만족도가 높을수록 대기오염에 대한 부정적 인식이 삶의 만족도에미치는 영향을 완충하는 것으로 나타났다. 본 연구의 결과는 삶의 만족도 저하 예방을 위해 녹지 환경이 중요한 자원으로고려되어야 하며, 지역사회에서 녹지 환경의 확장과 개선을 위한 다양한 방안들이 개발될 필요가 있음을 보여준다.

        Fallow Cover Crop Species and Nitrogen Rate of Fertigated Solution on Cucumber Yield and Soil Sustainability in Greenhouse Condition

        이성은,박진면,노재승,임태준 한국토양비료학회 2014 한국토양비료학회지 Vol.47 No.1

        Nutrient accumulation in surface soil has become a serious problem for cucumber production in greenhouse. However, still in many cases, soil management practices are only focused on maintaining crop yield,regardless of sustainability related with soil chemical properties. This study was conducted to propose asustainable soil management practice by investigating the impact of cover crop species and nitrogen rate offertigated solution on cucumber yield and soil chemical properties in greenhouse condition. Rye and hairyvetch were tested as a fallow cover crop, and each amount of urea (1/2, 3/4, 1 times of N fertilizerrecommendations), determined by soil testing result, was supplied in fertigation plots as an additional nitrogensource. The result showed that the yield of cucumber was higher in rye treatment than control and hairy vetchtreatment. In addition, rye effectively reduced EC and accumulated nutrients from the soil. Meanwhile, Nconcentration of fertigated solution showed no significant effect on the growth and yield of cucumber. Consequently, these results suggest that it is desirable to choose rye as a fallow catch crop for sustainablecucumber production in greenhouse.

      • 탄천수계분지내 하천수와 하상퇴적물의 지구화학적 특성에 관한 연구

        이성은 이화여자대학교 교육대학원 2003 이화교육논총 Vol.13 No.-

        In order to investigate the geochemical characteristics and contamination of dissolved major ions and heavy metals in the Tancheon River, river water and sediment samples were collected at 18 locations, along a distance of 69 km, between Yongin-si in Kyunggi-do and Samsung-dong in Seoul on October in 2000 and April in 2001. After appropriate sample preparation, waters were analyzed for the dissolved constituents and sediments. The pH values of river waters were in the range of 7.0 to 9.3 and could be plotted in the area of surface environment. The level of Ca2+, Cl-, SO42-, NO3- and HCO3- in the Tancheon River were higher than those in world average river water. Most of dissolved constituents in the river waters increased toward downstream from upstream. In particular, high concentrations of Zn2+, Na+, Cl-, SO42- and NO3- were found near densely residential areas and the Sung-nam waste water treatment plant. The relative ion enrichment was caused by the inflow of local domestic and industrial sewages. Also, Ca2+ and HCO3- concentrations were enriched in the middle of the Tancheon River due to the dissolution of cements. This indicates that the apartment complexes were built on a large scale in the upriver since these ten years and large amounts of construction materials such as cements were flowed into the Tancheon River. Concentrations of heavy metals (Mn, Cd, Cu, Pb, Zn) in sediments from the Tancheon River exceeded the lower limit of tolerence level in bottom sediment established by the Ontario Ministry of the Environment (OME) of Canada. In particular, these metals were highly elevated in sediment (TSM-12) collected from near the Sungnam waste water treatment plant. Heavy metals were higher enriched in sediments collected from dry period rather than wet period. From the result of sequential extraction analysis for sediments, relatively high proportion of Ca, Mn and Zn are present as exchangeable, carbonates fractions. This indicates that these elements are more mobile and bioavailable than other elements.

        아동의 문학이해능력 향상을 위한 웹 활용 인지적 도제학습 프로그램 개발

        이성은,전지영 한국초등국어교육학회 2005 한국초등국어교육 Vol.29 No.-

        본 연구는 웹을 활용한 인지적 도제 학습 프로그램을 개발·적용하여 실제 아동의 문학이해능력에 어떤 영향을 미치는지 알아보는데 목적이 있다. 이를 위해 요구조사를 실시하여 프로그램의 목적을 설정하고, 목적에 따른 내용조직과 학습자를 분석한 후, 수업 모형과 평가방법을 개발하였다. 개발된 프로그램은 초등학교 4학년 한 학급을 선정하여 웹 활용 인지적 도제 학습 프로그램을 8주 동안 적용하여 그 효과를 사전·사후 검사를 통해 알아보았다. 연구 결과, 웹 활용 인지적 도제 학습 프로그램은 아동의 문학이해능력에 유의미한 차이를 보였다. 특히 문학이해 능력의 하위요소 중 ‘구성 이해력', ‘주제 이해력'에서 보다 긍정적인 영향을 보였다. 후속 연구로, 다른 학년의 아동들을 대상으로 확장된 웹 커뮤니티를 이용한 연구나, 문체 등의 다른 문학요소와의 관계를 규명하는 연구가 이루어지도록 제언하였다. The purpose of this study was the developing a Web-based cognitive apprenticeship instruction program for advancing the literature understanding. competence. And to identify what impacts of this program have on the literature understanding, after applying the program to 33 fourth graders at M Elementary School in Seoul. For this purpose, the survey was carried out on teachers and pupils, in order to find out the recognition of literature understanding, difficulties in a literature understanding. After survey, the objective of this program has been established based on the 7th Korean language curriculum. And then a Web-based cognitive apprenticeship instruction program was developed by using fairly tale themes, which are friendly to children, in order to improve children's literature understanding competence. This program was applied to 18 sessions of classes during 8 weeks. As a results, the Web-based cognitive apprenticeship instruction program is effective to the improvement of literature understanding. In particular, the two elements, composition understanding and theme understanding, showed more significant differences than character understanding, among three sub-elements, when the pre and post evaluation results were compared. In conclusion, the research suggests the development of teaching method for web-based literature program and in practice lead to the actual improvement of the pupils' literature understanding competence.
