SW-PBIS가 인지발달장애학생들의 학력신장에 미치는 효과

홍사훈 ( Saa Hoon Hong ),류지훈 ( Ji Hoon Ryoo ) 한국특수교육문제연구소 2012 특수교육저널 : 이론과 실천 Vol.13 No.3

SW-PBIS는 학생들의 사회적 능력 습득과 향상을 지원하기 위한 포괄적인 학교환경의 변화를 제안하고 있다. 삼층 위계모형을 기반으로 한 SW-PBIS는 학생들이 바람직한 학습 태도, 행위규범, 소수에 대한 이해와 배려, 다양성 존중에 관한 교육기회를 제공한다. 도움이 필요한 학생들에게는 그들의 필요에 맞추어진 개별화된 혹은 특성화된 별도의 서비스를 제공한다. 이러한 체계적인 지원은 사회적 능력의 습득과 향상을 도울 뿐 아니라 일반학생들의 학력신장에도 기여하고 있는 것으로 알려져 있다. 본 연구는 경향점수를 활용하여 SW-PBIS와 경도 인지발달장애학생들의 학업성취도간의 관계에 대해 확인하고자 하였다. 연구의 결과, SW-PBIS를 통한 긍정적인 학교 환경의 변화는 특수교육요구학생들의 읽기 학력신장에 영향을 미치고 있음을 보여 주었다. 이는 학생들의 과목별 학업성취도와 관련된 다양한 변인들에 대한 후속연구의 필요성을 제기하고 있으며, 한국에서의 SW-PBIS 역할과 활용을 위한 논의의 방향을 제시하고 있다. This study examined the effects of SW-PBIS on special education student achievement by using propensity score matching. Propensity score matching methods allowed to identify a matched sample whose control group has similar characteristics as its experimental group. SW-PBIS schools and their matched samples were compared within model selection procedures using model fit index. The result indicated that special education student achievement growth in math was not associated with SW-PBIS while their growth in reading was associated with SW-PBIS. For Korean education, SW-PBIS could be introduced to support Korean character eduction and democratic civil education. Implication for Korean-version SW-PBIS application was also discussed.

학교 수준 학업 성취도에 대한 미네소타 교원성과급제의 효과에 관한 연구

홍사훈 ( Saa Hoon Hong ),류지훈 ( Ji Hoon Ryoo ) 부산대학교 과학교육연구소 2011 교사교육연구 Vol.50 No.2

미국의 교원성과급제는 학생의 학업 성취도를 주요 평가기준으로 사용하고 있다. 교원성과급제의 적용은 학력신장에 미치는 교원의 효능성에 관한 연구들과 함께 지속적으로 확대되고 있다. 이와 함께, 교원성과급제와 학력신장간의 관계를 분석하는 종단 연구의 필요성들이 제기되고 있다. 본 연구 는 학교 수준의 학력신장을 교원성과급제의 핵심으로 반영한 미네소타의 교원성과급제를 분석하였다. 이를 통해, 학력신장에 미치는 교원성과급제의 효과를 검증하고자 하였다. 본 연구의 결과, 미네소타의 교원성과급제는 초등학교 3, 4, 5학년의 학력신장에 기여하지 못하고 있음을 보여 주었다. 이러한 결과는 현 교원성과급제에 대한 후속 연구의 필요성과 함께, 교원성과급제 전반에 대한 심도 있는 재논의의 필요성을 확인시켜 주고 있다. Minnesota performance pay is intended to help with the recruitment and retention of high-ability teachers that leads to successful student learning, Linear Mixed Model(LMM) was employed to examine the effect of performance pay for teachers on student educational performance as measured by Minnesota Comprehensive Assessments II(MCA II) test scores in mathematics and reading assessments. The results indicated that there was no relationship between performance pay and school mean growth in MCA II tests; thus, this study provides empirical evidence showing that Minnesota performance pay tied to student achievement was not sufficient enough to improve school performance in academic assessments. The implications of this study are also discussed.

Hong, Saa Hoon,Ryoo, Ji Hoon 이화여자대학교 특수교육연구소 2010 특수교육 Vol.9 No.1

Linear Mixed Model(LMM) was employed to examine the effect of performance pay for teachers in overall educational performance in mathematics and reading assessments. The result indicated that there was no effect of performance pay on special education student learning, thus, this study provides the provisional result that performance pay should reorganize its current feature to support special education. The implications of this study are also discussed. 미국의 장애인 교육법(IDEA, 1997)과 아동낙오방지법(NCLB, 2001)은 표준화된 학업성취도 검사에서 특수교육 대상학생들도 예외일 수 없음을 명시하고 있다. 이는, 학생들의 학업 성취도를 매년 측정함으로써 특수교육 대상학생들을 포함한 다양한 학생 그룹 간의 학력격차를 완화시키고자 함이다. 미네소타의 교원성과급제(Q Comp)는 교수 방법의 효율성 증진을 통한 학생들의 학업성취도 향상을 목적으로 하고 있다. Q Comp은 교사 재교육과 표준화된 평가도구를 통한 교수 관찰의 정례화, 그리고 학생들의 학업성취도에 따른 성과급 지급을 주된 내용으로 한다. 본 연구의 주된 연구 목적은 Q Comp과 특수교육 대상학생의 학업 성취도와의 관계를 밝히는 것이다. 본 연구의 종속변인인 학업 성취도는 미네소타 표준화 학력검사(MCA II)를 통해 2006년부터 2008년까지 3년간 수집되었다. 미네소타 주에서 MCA II는 3학년부터 8학년까지의 모든 학생들이 치러야 하는 시험이며, 10학년 읽기 시험과 11학년 수학 시험은 미네소타의 고등학교 졸업장을 얻기 위해서 반드시 통과해야 하는 시험이다. 선형혼합모형(Linear Mixed Model; LMM)을 통해 Q Comp과 초등학교 특수교육 대상학생의 학업 성취도와의 관계를 분석한 결과, Q Comp은 초등학교 3, 4, 5학년의 읽기와 수학 성취도에 통계적 유의성을 보이지 못하고 있었다. 이는 교원성과급제를 통한 학교 개혁의 노력들이 특수교육 대상학생의 학력신장에는 별다른 영향을 미치지 못하고 있음을 보여주는 것이다. 본 연구의 결과는 특수교육 대상학생의 학업 성취 향상을 위한 특수교사와 일반교사에 대한 교원성과급제의 역할과 그 구성요소들에 대한 후속 연구의 필요성을 확인시켜 주고 있다.

The Influence of Elevated CO2 on Photosynthesis, Carbohydrate Status, and the Plastochron in Young Peach (Prunus persica) Trees

Anna M. Davidson,David Da Silva,Sebastian Saa,Phillip Mann,Theodore M. DeJong 한국원예학회 2016 Horticulture, Environment, and Biotechnology Vol.57 No.4

The plastochron, defined as the time interval between the initiations of two successive leaves, can also indicate the development of successive phytomers along a shoot. Previous work has shown that crop load impactsthe plastochron in field-grown peach (Prunuspersica) trees, which led us to hypothesize that the plastochron of peach trees may be sensitive to the carbon status of the tree. To testthis hypothesis, a 38-day growth chamber study was conducted to determine if elevated CO2 (800 μmol·mol-1) speeds up the plastochron of young peach trees relative to their growth in ambient (400 μmol·mol-1) CO2. The leaf lamina lengths were measured every other day to generate leaf growth rate curves that were fitted against a classic Gompertz growth curve to estimate the time of the initiation of each leaf, which in turn, was used to estimate the plastochron. Additionally, in order to non-destructively gauge the effects of CO2 concentration on plant performance during the experiment, net leaf CO2 assimilation and stomatal conductance measurements were taken approximately half way through and at the end of the 38-day experiment. Doubling the ambient CO2 concentration had no effect on the plastochron, even though the leaf CO2 assimilation rates, leaf starch and total nonstructural carbohydrate concentrations were greater in trees grown in elevated CO2. In addition, there were no significant treatment differences in incremental shoot growth or the number of lateral syleptic shoots.

The Interplay between Comprehensive Use of Performance Management Systems and Corporate Financial and Non-Financial Performance: Evidence from Saudi Arabia

Ahmed Abdullah Saad AL-DHUBAIBI(Ahmed Abdullah Saad AL-DHUBAIBI ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1

A significant body of prior research on performance management systems (PMSs) either explains the components and the design of the systems or investigates the link between particular system/s and organizational functions, capabilities, or performance. In contrast, this study investigates the comprehensive use of PMSs and relates them to corporate financial and non-financial performance. Further, this study examines whether the association between PMSs and performance varies between industries or is moderated by the size of the company. Data was collected using a questionnaire that was sent to companies from different industries operating in Riyadh province, where the most important businesses in Saudi Arabia are located. A total of 152 usable responses were received. The results of this study revealed that companies use a variety of PMSs at a balanced level. The extent of each category of PMS use is associated with the extent of other PMS categories’ use. However, the larger the company, the more PMSs it uses. Importantly, the results showed a positive and significant association between PMSs’ extent of use and both financial and non-financial performance. This association was minimally moderated by the company size and industry for specific categories of PMSs and performance.

Carlos Alberto Velasco-Benítez,Laura Isabel Collazos-Saa,Herney Andres García-Perdomo 대한소아소화기영양학회 2022 Pediatric gastroenterology, hepatology & nutrition Vol.25 No.5

Functional gastrointestinal disorders (FGIDs) are classified as a combination of persistent gastrointestinal symptoms. The Rome IV criteria can elucidate several factors in the pathogenesis of FGIDs. The frequency of FGIDs can differ between clinical and nonclinical settings and between geographic regions. To determine the global prevalence of FGIDs in neonates and toddlers according to the Rome IV criteria. We included cohort and descriptive observational studies reporting the prevalence of FGIDs according to the Rome IV criteria in children aged 0–48 months. We searched the Medline, Embase, Lilacs, and CENTRAL databases from May 2016 to the present day. Furthermore, unpublished literature was searched to supplement this information. The Strengthening the Reporting of Observational Studies in Epidemiology statement was used to evaluate the risk of bias. A meta-analysis of the proportions was performed using MetaProp in R. The results are reported in forest plots. We identified and analyzed 15 studies comprising 48,325 participants. Six studies were conducted in Europe, three in Latin America, two in North America, and four in Asia. Most participants were 12–48 months old (61.0%) and were recruited from the community. The global prevalence of FGIDs was 22.0% (95% confidence interval, 15–31%). The most common disorder was functional constipation (9.0%), followed by infant regurgitation syndrome (8.0%). Its prevalence was higher in the Americas (28.0%). FGIDs, as defined by the Rome IV criteria, are present in 22% of children, and the most common primary disorder is functional constipation. A higher prevalence of FGIDs has been reported in America.

Experimental Study of the Dry Facing of Magnesium Pieces Based on the Surface Roughness

Eva Maria Rubio,Jose Luis Valencia,Adolfo Jose Saa,Diego Carou 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.

This paper shows an experimental study of dry face turning carried out on UNS M11917 magnesium pieces. The work is focused on repair and maintenance operations which are generally carried out under cutting conditions of low performance. The main goal is to determine if such type of operations can be reached successfully by dry machining, the most drastic and sustainable cooling technique that exists, and, if so, what factor or factors among the involved ones in the machining (spindle speed, feed rate and tool coating) and their possible interactions are more influential in the quality of surface finish. To achieve this objective, a sustainable methodology that combines Taguchi design of experiment (DOE) and the analysis of variance (ANOVA) method are considered. The main result is the establishment of a model for estimating the expected surface roughness,in terms of average roughness, Ra, that allows selecting the best combination of cutting conditions and type of tool to obtain pieces within a certain range of surface roughness. The principal conclusion is that the dry machining technique can be used in the face turning repair and maintenance operations of pieces of magnesium producing a very good quality of the surface roughness and reducing costs and environmental impact.
