        국내 유아교육 관련 메타분석 논문의 방법론적 질 평가

        박서현 ( Park Seo Hyun ) 한국유아교육학회 2018 유아교육연구 Vol.38 No.5

        본 연구의 목적은 국내 유아교육 분야에서 출간된 메타분석 논문의 특성 및 현황을 살펴보고 타당성과 신뢰성이 검증된 AMSTAR 평가 도구를 활용하여 메타분석 논문들의 방법론적 질을 평가하는 것이다. 유아 및 유아교육과 메타분석을 주요어로 국회도서관, KISS, RISS 데이터베이스를 이용하여 학위논문 및 학술지 게재 논문을 검색한 결과, 최종적으로 본 연구의 목적에 맞는 70개의 메타분석 논문이 선정되었다. 70개의 논문은 AMSTAR의 11 항목별로 질적 평가가 이루어졌으며 수집된 자료는 기술통계, 독립표본 t 검정, 일원분산분석으로 분석되었다. 분석 결과 유아교육분야에서는 2011년 이후 급속한 양적 증대와 다양한 주제로 메타분석이 실시되고 있음을 확인할 수 있었다. 메타분석 연구의 질 평가 점수는 AMSTAR 기준 11점 만점에 5.44(SD=1.44)로 보통 수준이었으며, 낮은 수준은 18편(25.7%), 중간 수준은 50편(71.4%), 그리고 높은 수준은 2편(2.9%)으로 분류되었다. 2011년을 기준으로 질 평가 점수 간 유의미한 차이가 있어, 최근 출간된 메타분석 논문일수록 메타분석의 질 평가 점수가 높게 나타났다. 이와 같은 결과를 통해 유아교육 분야에서 수행된 메타분석은 방법론적인 분석과정에 따라 어느 정도 충실히 수행하고 있는 것으로 나타났지만, 전반적으로 개별 연구에 대한 미흡한 질적 평가와 메타분석 연구에 대한 질적 제고없이 양적으로만 확산되어 왔다. 이에 개별 연구들에 대한 충분한 질 검토 및 메타분석 연구의 질 향상을 위한 노력이 지속되어야 할 필요가 있다. The purpose of this study was to explore the trends of meta-analysis studies in early childhood education and evaluate the methodological quality of meta-analysis studies using AMSTAR, a validated tool for assessing the quality of systematic reviews. Through the National Assembly Library, KISS, and RISS database with early childhood education and meta-analysis as searching key words, 70 meta-analysis studies were selected in accordance with the purpose of this study. AMSTAR was scored for quality assessment of the 70 studies. Data were analyzed using descriptive statistics, independent t-test, and one-way ANOVA. The results of this study were as follows. Since 2011, the number of meta-analysis studies in early childhood education has rapidly increased with a variety of subjects. The mean score for the methodological qualitative evaluation was 5.44(SD=1.44); 18 studies were rated as low quality, 50 as moderate quality, and 2 as high quality. The scores of quality were statistically significant, in that they showed differences by publication year and research design. In particular, the most recently published studies tended to have higher scores of meta-analysis assessment for review. The results proved that meta-analysis studies in early childhood education have satisfied the functions of methodological procedures in general. However, meta-analysis studies have increased quantitatively without proper quality evaluation of individual studies and quality improvement. Efforts to review the sufficiency in quality of individual studies and to improve the quality of the meta-analysis studies should be continued.

        Polymerized mesoporous nature zeolites (pMNZ) was simply prepared by acid treatment and polymerization of metaclic acid, which evaluated as adsorbents for the removal of cationic/anionic heavy metals from aqueous solutions. The effects of treatment time and different acids during synthesis on the pore structure of the MNZ were studied, and the pMNZ samples were characterized by nitrogen full isotherms, XRF analysis, and FT-IR spectroscopy. The MNZ prepared using hydrochloric acid had higher meso pore volume, and surface area. The BET analysis showed that the surface area of MNZ is 82 m2/g greater than that of natural zeolite that is 39 m2/g. We investigated the adsorption ability of pMNZ for metal ions (Cu (II), Mn (II), and As (V)) and evaluated the influence of pH. The removal efficiencies of pMNZ for Cu(II), Mn(II), As(V) were 44%, 51%, 99% and qe were 0.88, 0.75, 0.04, respectively. In addition, the adsorption kinetics were evaluated using pseudo-first-order and pseudo-second-order models. The internal and external diffusion models were studied to explain the adsorption process in pMNZ. The adsorption capacity resulted that the pMNZ could eliminate the anionic, cationic metal ions from aqueous solution at pH range of 6-10 and different kinetics were examined to explain the adsorption process.

        메조 세공 제올라이트 Y가 코팅 된 알루미나 중공사막을 이용한 중금속 흡착

        박서현 ( Seo-hyun Pak ),박정훈 ( Jung Hoon Park ),박찬규 ( Chan-gyu Park ) 한국수처리학회 2021 한국수처리학회지 Vol.29 No.2

        In this study, mesoporous-zeolite-Y-coated alumina hollow fiber membranes were prepared by optimizing the synthesis conditions and using commercial zeolite Y, CTAB, as the structure-directing agent and alumina hollow fiber membranes. The removal of heavy metals was investigated using these membranes. The synthesized membranes were characterized with X-ray diffraction, field emission scanning electron microscopy, nitrogen adsorption-desorption analysis, field emission transmission electron microscopy, Fourier transform infrared spectroscopy, and the heavy metal adsorption activity of these membranes was investigated with ultraviolet-visible spectroscopy. Batch tests were conducted to investigate the capabilities of the mesoporous-zeolite-Y-coated membranes in removing Mn (II) and Fe (II)fromaqueoussolutions.Nitrogen full isotherm analyses confirmed that the synthesized mesoporous adsorbents were homogenously mesoporous. These results suggest that the mesoporous-zeolite-Y-coated membranes exhibited higher adsorption capacity than that of the alumina hollow fiber membranes. After three runs of heavy metal adsorption, there was no drop in the activity of the prepared mesoporous-zeolite-Y-coated alumina hollow fiber membranes because they were easier to separate and more durable than the conventional powdered adsorbents.

        Polydopamine (PDA)-TiO₂ 코팅 유리섬유 직물을 이용한 VOCs의 저감 성능 및 항균성 연구

        박서현(Seo-Hyun Park),최예인(Yein Choi),이홍주(Hong Joo Lee),박찬규(Chan-gyu Park) 한국환경보건학회 2021 한국환경보건학회지 Vol.47 No.6

        Background: Indoor air pollutants are caused by a number of factors, such as coming in from the outside or being generated by internal activities. Typical indoor air pollutants include nitrogen dioxide and carbon monoxide from household items such as heating appliances and volatile organic compounds from building materials. In addition there is carbon dioxide from human breathing and bacteria from speaking, coughing, and sneezing. Objectives: According to recent research results, most indoor air pollution is known to be greatly affected by internal factors such as burning (biomass for cooking) and various pollutants. These pollutants can have a fatal effect on the human body due to a lack of ventilation facilities. Methods: We fabricated a polydopamine (PDA) layer with Ti substrates as a coating on supported glass fiber fabric to enhance its photo-activity. The PDA layer with TiO2 was covalently attached to glass fiber fabric using the drop-casting method. The roughness and functional groups of the surface of the Ti substrate/PDA coated glass fiber fabric were verified through infrared imaging microscopy and field emission scanning electron microscopy (FE-SEM). The obtained hybrid Ti substrate/PDA coated glass fiber fabric was investigated for photocatalytic activity by the removal of ammonia and an epidermal Staphylococcus aureus reduction test with lamp (250 nm, 405 nm wavelength) at 24°C. Results: Antibacterial properties were found to reduce epidermal staphylococcus aureus in the Ti substrate/ PDA coated glass fiber fabric under 405 nm after three hours. In addition, the Ti substrate/PDA coated glass fiber fabric of VOC reduction rate for ammonia was 50% under 405 nm after 30 min. Conclusions: An electron-hole pair due to photoexcitation is generated in the PDA layer and transferred to the conduction band of TiO₂. This generates a superoxide radical that degrades ammonia and removes epidermal Staphylococcus aureus.

        반사회적 성향과 공격성의 관계에서 초기 부적응 도식의 매개 효과

        박서현 ( Seo Hyun Park ),채규만 ( Kyu Man Chae ) 서강대학교 학생생활상담연구소 2011 人間理解 Vol.32 No.2

        본 연구는 반사회적 성향과 공격성의 관계에서 초기 부적응 도식의 매개효과를 검증해 보고자 하였다. 성인 609명을 대상으로 반사회성 척도, 공격성 척도, 초기 부적응 도식 척도를 사용하여 설문을 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 상관분석 결과, 반사회성과 초기 부적응 도식은 공격성과 정적 상관을 보였다. 둘째, 전체 집단을 분석한 결과, 초기부적응 도식은 반사회성과 공격성의 관계에서 부분매개효과를 보였다. 매개한 도식은 불신, 특권의식, 유기, 위험, 고립, 부족한 자기 통제, 정서적 억제, 결함, 융합, 엄격한 기준, 의존, 정서적 결핍, 복종, 실패 순이었다. 셋째, 성별로 검증해 본 결과, 남성 집단에 매개한 도식은 불신, 특권의식 다음으로 설명량이 큰 것이 고립 도식이었으며 남성 집단에서만 정서적 결핍, 복종, 실패 도식이 나타났다. 여성 집단은 위험 도식이 가장 큰 설명량을 보였고, 남성 집단과 달리 엄격한 기준 도식이 유의미하게 나타났다. 본 연구는 개인의 초기 부적응 도식을 파악하여 심리 치료에 활용하는 것은 물론 공격성 감소 프로그램을 개발하는 데에 도움이 될 수 있다는 점에 의의가 있다. This study examined the mediating effect of early maladaptive schemas in the relation between antisocial personality and aggression. A total of 609 participants filled out the MMPI-2 Psychopathic Deviate scale, the Aggression Question-Korean version, and the Young Schema Questionnaire-Short Form. Correlational analyses revealed that antisocial personality and early maladaptive schema were positively related to aggression. Additionally, results from hierarchical multiple regression analyses indicated that early maladaptive schemas partially mediated the link between antisocial personality and aggression. For male participants, schemas regarding mistrust, entitlement, and social isolation accounted for the variance in aggression the most, whereas schema regarding harm was the case. The findings imply that early maladaptive schema should be a variable to consider, especially in designing a program whose main purpose is to reduce aggression.

        The purpose of this study was to examine the relationship among nursing professionalism, job satisfaction, and role conflict of nurses in comprehensive nursing care unit. Data were collected using self-reported questionnaires from 116 nurses in comprehensive nursing care units. The result show that nursing professionalism was positively correlated with job satisfaction and job satisfaction was negatively correlated with role conflict. However, there was no statistically significant correlation between nursing professionalism and role conflict. In order to provide high quality nursing services in comprehensive nursing care unit, it is necessary to develop and apply a nursing professionalism promotion strategy that can control role conflict with the enhancement of job satisfaction.
