공감활동이 유아 정서조절능력과 배려행동에 미치는 영향에 대한 연구
권민정(Minjeong Kwon),문미숙(Misook Moon),조동혁(Donghyuk Jo) 글로벌경영학회 2022 글로벌경영학회지 Vol.19 No.5
본 연구의 목적은 그림책을 활용한 공감활동이 유아의 정서조절능력과 배려행동에 미치는 효과를 확인하는 것으로 기존 유아 정서조절능력을 측정하기 위한 선행연구에서의 측정도구를 사용하여 만 4세 유아 34명을 대상으로 실험 집단과 통제집단 그룹 17명씩을 배치하여 실험을 진행하였다. 실험은 총 7주간 14회에 거쳐 진행되었으며 그림책 활용이 유아 정서조절과 배려행동에 영향을 미치는지에 대해 사전, 사후 검사를 실시하여 t-test를 실시함으로써 검증하였다. 연구결과 첫째로 그림책 활용 공감활동은 전체적인 정서조절 능력을 향상시키는 효과를 검증할 수 있었지만 하위요인인 적응적 정서조절과 부정 정서조절의 경우 통계적으로 효과를 검증하지 못하였다. 둘째로 그림책 활용은 전체적인 배려행동을 향상시키는 효과뿐만 아니라 배려행동의 하위요인을 향상시키는 영향을 통계적으로 검증하였다. 이를 통해 그림책을 활용한 유아 활동은 유아에게 상대방의 생각과 감정을 인식하고 알맞게 조절하고 유지하며 상대방을 배려하는 행동에 대해 긍정적인 효과가 있다는 것을 검증하였다. 향후 연구에서는 정서조절능력과 배려행동의 하위요인이 보다 더 구체적으로 연결되어 측정할 수 있는 측정도구들이 개발되어 연구에 활용이 필요하다. The purpose of this study is to determine the effect of sympathetic activity using picture books on children's emotional regulation ability and considerate behavior. The experiment was conducted by placing 17 people each in an experimental group and a control group. The experiment was conducted 14 times over 7 weeks, and it was verified by conducting pre- and post-tests on whether the use of picture books had an effect on infant emotional regulation and considerate behavior. As a result of the study, first, the effect of sympathetic activity using picture books to improve overall emotion regulation ability could be verified, but the effects of adaptive emotion regulation and negative emotion regulation, which are sub-factors, could not be verified statistically. Second, the effect of using the picture books on improving not only the overall considerate behavior but also the sub-factors of the considerate behaviors were statistically verified. Through this, it was verified that children's sympathetic activities using picture books have a positive effect on children's behaviors to recognize the thoughts and emotions of the other person, adjust and maintain them appropriately, and be considerate of the other person. In future research, measurement tools that can connect and measure the sub-factors of emotional regulation ability and considerate behavior more specifically are developed and need to be utilized in research.

AOPWIN을 이용한 Acetanilide의 광분해 특성 평가
권민정,최윤호,송상환,박혜연,구현주,정성환,나진균,박광식 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.3
Acetanilide is a High Production Volume Chemical, which is produced about 2,300 tons/year in Korea as of 1998 survey. Most is used as an intermediate for synthesis of pharmaceuticals and dyes, and the chemical is one of seven chemicals of which human and environmental risk are being assessed by National Institute of Environmental Research under the frame of OECD SIDS program. The Atmospheric Oxidation Program for Microsoft Windows (AOPWIN) is used to estimates the rate constant for the atmospheric, gas-phase reaction between photochemically produced hydroxyl radicals and organic chemicals. It is also used to estimates the rate constant for the gas-phase reaction between ozone and olefinic/acetylenic compounds. The rate constants estimated by the program are then used to calculate atmospheric half-lives for organic compounds based upon average atmospheric concentrations of hydroxyl radicals and ozone. AOPWIN requires only a chemical structure to make these predictions. Structures are entered into AOPWIN by SMILES (Simplified Molecular Input Line Entry System) notations. In this study, one of environmental fate/distribution of the chemical elements, photodegradation of acetanilide was estimated using AOPWIN model based on SMILES notation and chemical name data.

BCF WIN을 이용한 Acetanilide의 생물농축특성 평가
권민정,최윤호,송상환,박혜연,구현주,박광식 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4
Acetanilide is a High Production Volume Chemical, which is produced about 2,300 tons/year in Korea as of 1998 survey, Most is used as an intermediate for synthesis of pharmaceuticals and dyes. The chemical is one of seven chemicals, which are under the frame of OECD SIDS program sponsored by National Institute of Environmental Research of Korea, Regarding the information on the environmental fate, bioconcentration is one of important factor to estimate the environmental tranfer. However, measurement of bioconcentration needs high expense and time. For this reason, OECD recommends to use BCFWIN model to estimate bioconcentration of organic chemicals. BCFWIN estimates the bioconcentration factor(BCF) of an organic compound using the log octanol-water partition coefficient (Kow) of the compound. Structures are entered into BCFWIN through SMILES (Simplified Molecular Input Line Entry System) notations, The BCFWIN method classifies a compound as either ionic or non-ionic. Ionic compounds include carboxylic acids, sulfonic acids and salts of sulfonic acids, and charged nitrogen compounds (nitrogen with a +5 valence such as quaternary ammonium compounds). All other compounds are classified as non-ionic. In this study, bioaccumulation of acetanilide was estimated using BCFWIN model based on SMILES notation, chemical name data and partition coefficient as one of environmental fate/distribution of the chemical elements.

EQC모델을 이용한 Acetanilide의 환경중 분포예측
박광식,권민정,최윤호,송상환,박혜연,구현주 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.3
Acetanilide is a High Production Volume Chemical, which is produced about 2,300 tons/year in Korea as of 1998 survey. Most is used as an intermediate for synthesis of pharmaceuticals and dyes and the chemical is one of seven chemicals of which human and environmental risks are being assessed by National Institute of Environmental Research under the frame of OECD SIDS program. The chemical is water soluble (4 g/l at 20℃) and readily biodegradable (68.7%). Partition coeff iciency (Log Pow) is 1.16 at 23? so that the chemical has a low potential for bioaccumulation. The acute toxicities of algae, daphnia and fish are not high. The 72 hr-E_(b)C50 of algae is 13.5 mg/1, 48 hr-EC50 of daphnia is over 100 mg/l and 96 hr-LC50 of Oryzias latipes is over 100 mg/l. Regarding the exposure, levels in air, water, soil or sediment have not been monitored or estimated so that risk evaluation of acetanilide was not possible. In this study, distribution of the chemical among environmental media was estimated using EQC model based on the chemical-physical properties. In Level Ⅰ and Ⅱ of which the chemical are hypothesized in equilibrium and no transfer through the media, more than 98% of acetanilide are estimated to be distributed in water. However, in Level Ⅲ of which non-equilibrium and intermedia transfer could be occurred, the chemical is estimated to distributed to soil as 51.8% and water as 47.8% as of total amount.
