남종오,심성현 한국해양과학기술원 2014 Ocean and Polar Research Vol.36 No.4

This study aims to analyze causality among Wando abalone producer prices by size using a vector autoregressive model to expiscate the leading-price of Wando abalone in various price classes by size per kg. This study, using an analytical approach, applies a unit-root test for stability of data, a Granger causality test to learn about interaction among price classes by size for Wando abalone, and a vector autoregressive model to estimate the statistical impact among t-1 variables used in the model. As a result of our leading-price analysis of Wando abalone producer prices by shell size using a VAR model, first, DF, PP, and KPSS tests showed that the Wando abalone monthly price change rate by size differentiated by logarithm were stable. Second, the Granger causality relationship analysis showed that the price change rate for big size abalone weakly led the price change rate for the small and medium sizes of abalone. Third, the vector autoregressive model showed that three price change rates of t-1 period variables statistically, significantly impacted price change rates of own size and other sizes in t period. Fourth, the impulse response analysis indicated that the impulse responses of structural shocks for price change rate for big size abalone was relatively more powerful in its own size and in other sizes than shocks emanating from other sizes. Fifth, the variance decomposition analysis indicated that the price change rate for big size abalone was relatively more influential than the price change rates for medium and small size abalone.

Background: Trial sequential analysis (TSA) is a recent cumulative meta-analysis method used to weigh type I and II errors and to estimate when the effect is large enough to be unaffected by further studies. The aim of this study was to illustrate possible TSA scenarios and their significance using meta-analyses published in the Korean Journal of Anesthesiology (KJA) as working material. Methods: We performed a systematic medical literature search for meta-analyses published in the KJA. TSA was performed on each main outcome, estimating the required sample size on the calculated effect size for the intervention, considering a type I error of 5% and a power of 90% or 99%. Results: Six meta-analyses with a total of ten main outcomes were included in the analysis. Seven TSAs confirmed the results of the meta-analyses. However, only three of them reached the required sample size. In the two TSAs, the cumulative z-lines were not statistically significant. One TSA boundary for effect was reached with the 90% analysis, but not with the 99% analysis. Conclusions: In TSA, a meta-analysis pooled effect may be established to assess if the cumulative sample size is large enough. TSA can be used to add strength to the conclusions of meta-analyses; however, pre-registration of the TSA protocol is of paramount importance. This study could be useful to better understand the use of TSA as an additional statistical tool to improve meta-analysis quality.

A Study on Mesh Size Dependency of Finite Element Blast Structural Analysis Induced by Non-uniform Pressure Distribution from High Explosive Blast Wave

남진원,김장호,김성배,이나현,변근주 대한토목학회 2008 KSCE Journal of Civil Engineering Vol.12 No.4

Accurate computational blast analysis can be an effective replacement for costly blast field test. HFPB (high fidelity physics based)blast analysis method including high strain rate dependent material models and appropriate blast wave models is a representativeprecise blast analysis method. HFPB blast analysis method can be used for various analyses such as structural analysis, retrofittingdesign analysis, fragmentation analysis, and energy absorbing analysis. When analyzing the behaviour of structure under blastloading by HFPB finite element methods, load gradient differences occurs dependent on the mesh size. This causes gaps between theexplosive energy and internal energy of structures and the results of analysis become mesh-size-dependent. In this study, theanalytical considerations were presented for mesh sensitivity due to non-uniform pressure load distribution on the structure subjectedto blast wave of high explosive with relatively close stand-off. Through the analysis results, the maximum element size whichensures the mesh-size independent analysis results is suggested.

김재호,김택원,우수한 한국항해항만학회 2015 한국항해항만학회지 Vol.39 No.6

This study objects to find characteristics in chemical tanker markets and to determine optimal chemical tanker size using a total shipping cost in main trading route of asia chemical tankers .Precedent studies of determination of the optimal ship size and case studies about chemical tankers was carried out and tried to introduce a cost model which is applicable to chemical tanker. This study is dependant on numerical analysis and involves scenario analysis to minimize sensitivity of results. This analysis shows as follows. First, 12,000DWT tanker is an optimal size on the 'Far East-Middle East' services, 9,000DWT tanker is a most competitive on the 'Far East-South East Asia' services and 3,000DWT tanker is a most economic size on the 'Inner Far East' services at average market situation. Second, the bigger size of chemical tanker, the more competitive advantage the tanker will obtain when bunker fuel prices rise. Small size ship gets more competitive during bunker prices down. Third, market fluctuation of time charter rate for chemical tanker is less than 20% against its average time charter hire which means less volatile. And tanker's competitiveness per each size is remained mostly same when time charterer rates rise at same proportion. Fourth, bigger size chemical tankers have cost advantages when tanker's quantity of each part cargo increase. And small-sized tanks are more competitive when part cargo scales decrease. For the last, ship's port stay strongly influences on the determination of the optical tanker size. When vessel has shorter port stay, bigger-sized tanker will be more competitive and even can be competitive if applies in short voyage as well. 본 연구는 아시아 케미컬 탱커 시장을 구성하는 수요 및 공급적 특성을 알아보고 케미컬 탱커선의 주요 비용을 파악하여 탱커시장의 주요 노선별로 최적선형을 제시하는 것이다. 따라서 본 연구는 선박 운항 상 비용분석에 관한 선행연구사례를 파악하고 케미컬 탱커 관련 연구를 통해 케미컬 탱커선에 적용 가능한 비용모델을 파악하였다. 또한 각 비용요소에 해당하는 데이터를 수치해석(Numerical Analysis)하고 연구결과의 민감도를 최소화하기 위해 시나리오 분석을 시행하였다. 그 결과 다음과 같이 다섯 가지의 시사점을 도출할 수 있다. 첫째, 연구대상 선형에서 평균적인 마켓상황을 가정했을 때, ‘극동-중동 노선’에서는 12,000DWT급 선형, ‘극동-동남아시아 노선’에서는 9,000DWT급 선형, 극동지역 내 에서는 3,000DWT급이 비용측면에서 경쟁력을 보일 수 있다. 둘째, 케미컬 탱커의 선박 사이즈가 커질수록, 연료의 가격이 상승함에 따른 경쟁우위가 높아지고 작은 사이즈의 경우 연료가격이 하락할 경우 경쟁우위가 높아지는 것으로 나타났다. 셋째, 케미컬 탱커의 용선료 변동은 호황기와 불황기의 표준편차가 20%미만으로 시황의 영향을 덜 받는 것으로 나타났으며, 비슷한 비율로 상승 시 사이즈별 경쟁력에는 큰 차이가 없는 것으로 나타났다. 넷째, 케미컬 탱커의 Parcelling의 규모가 커질수록 큰 사이즈의 케미컬 탱커가 경쟁력을 가지며 반대의 경우 작은 탱커의 경쟁력이 상승하는 것으로 나타났다. 마지막으로, 케미컬 탱커의 재항시간은 선박의 비용측면에 큰 영향을 미치는데 재항시간이 감소할 경우 큰 사이즈의 선박 경쟁력이 더욱 상승하여 보다 짧은 루트에 투입하여도 경쟁력이 있는 것으로 나타났다.

This study is supposed to clarify the relationship among factors on sale price depending on architectural size of commercial residential complexes using Path Analysis. Spatial scope of this study covers 193 commercial residential complexes located in the city of Seoul, and temporal scope covers commercial residential complexes having been completed by September 2008. In order to classify patterns pursuant to architectural size, K-means Cluster Analysis was performed using building area, total area and site area, and patterns were classified into two kinds such as big groups and small groups in architectural size, showing that there is about 1.4 million won difference in average sale price per ㎡ through T-test verification. In order to take a look at price determinants by architectural size patterns and grasp the relationship between them, analysis using Path Analysis to analyze the theoretical relation between configuration concepts and the relationship with measurement indices was performed, thereby developing each route model. Analysis results showed that big groups in architectural size were affected by the order of complex size, housing size, constructor brands, surrounding environments, composite facility size, complex access facilities, life convenience facilities and use zoning, and that small groups in architectural size were affected by the order of housing size, constructor brands, surrounding environments, complex access facilities, composite facility size, use zoning, complex size and life convenience facilities. 본 연구는 경로분석모형을 이용하여 주상복합아파트의 건축규모에 따라 매매가격에 미치는 요인들 간의 관계성을 규명하고자 하였다. 공간적 범위는 서울시에 입지하고 있는 주상복합아파트(193개)를 대상으로 하였으며 시간적 범위로는 2008년 9월까지 준공된 주상복합아파트를 중심으로 연구를 진행하였다. 건축규모에 따라 유형을 분류하기 위해 건축면적과 연면적, 대지면적을 이용하여 K-평균 군집분석을 실시하였으며, 건축규모가 큰 집단과 작은 집단 등 두 가지 유형으로 분류하였고 T-test검증을 통하여 ㎡당 평균 매매가격은 약 140만 원의 차이가 있음을 알 수 있었다. 건축규모 유형별 가격결정요인을 알아보고 상호 관계를 파악하고자 구성개념 간의 이론적 인과관계와 측정지표와의 관계를 분석할 수 있는 경로분석모형 분석을 실시하였으며, 이에 따른 결과로 각각의 경로모형을 개발하였다. 분석 결과 건축규모가 큰 집단은 단지규모, 주택규모, 건설사브랜드, 주변환경, 복합시설규모, 단지접근시설, 생활편의시설, 용도지역순으로 영향을 미치는 것으로 나타났으며, 건축규모가 작은 집단은 주택규모, 건설사브랜드, 주변환경, 단지접근시설, 복합시설규모, 용도지역, 단지규모, 생활편의시설순으로 영향을 미치는 것으로 나타났다.

김성희 한국스포츠학회 2021 한국스포츠학회지 Vol.19 No.4

본 연구는 코어 트레이닝 효과를 종합하기 위하여 기존 선행연구를 수집한 뒤 메타분석을 적용하였다. 이를 위해 13편의 논문을 중심으로 체계적 문헌 고찰과 메타 분석적 접근을 수행했다. 분석결과를 중심으로 내용을 기술해보면 다음 과 같다. 첫째, 전체 효과 크기를 분석한 결과 Hedges’ g 값은 .713으로 나타났다. 둘째, 코어 트레이닝이 남녀 집단 모두에 서 효과적임을 입증하였다. 셋째, 질환 여부에 따른 효과차이 검증 결과 두 집단 간 효과크기의 차이는 통계적으로 유의미 하였다. 넷째, 참여 빈도에 따른 효과차이 검증 결과 참여 빈도가 증가하면 코어 트레이닝의 효과가 더욱 증가한다는 것을 확인하였다. 다섯째, 참여시간을 독립변수로 효과크기를 종속변수로 설정한 뒤 메타-회귀분석(meta-regression)을 실시한 결과 참여시간의 증가는 효과크기에 유의한 영향을 미치지 않는 것으로 나타났다. In order to put together the effects of core training, this study collected the existing preceding researches, and then applied the meta-analysis. For this, after going through the PICO set-up process, this study performed the systematic literary review and meta-analytic approach focusing on total 13 theses. The results of the analysis could be described as follows. First, in the results of analyzing the overall effect size, the Hedges’ g value was .713. Second, in the results of verifying the effect differences between sex, the effect size of men was .798 while the effect size of women was .709. The difference in effect size between two groups was not statistically significant, which verified the effects of core training on both groups of men and women. Third, in the results of verifying the effects according to the matter of disease, in case when there was a specific disease, the effect size was .358. When there was no specific disease, the effect size was .765. The difference in effect size between two groups was statistically significant. Fourth, in the results of verifying the effect differences according to the frequency of participation. in case of three times a week, the effect size was .703. In case of four times a week, the effect size was 1.516. The difference in effect size between two groups was statistically significant. This verified that the effects of core training would be more increasing when the frequency of participation increased. Fifth, in the results of conducting the meta-regression analysis after setting up the participation hours as an independent variable and the effect size as a dependent variable, the increase of participation hours did not have significant effects on the effect size.

The papers for the analysis were experimental studies on children with developmental delay through the meta - analysis of the effect size from 2008 until recently. This is because the Special Education Law for persons with disabilities and others was enacted in 2008. The purpose of this study was to verify the effect size and to search for further research direction. For this purpose, They analyzed the total effect size (ES) of the group experimental research papers published in domestic journals and post - doctoral theses from 2008 to April 2018. The effect sizes of independent variables, dependent variables, and publishing types were also analyzed. The size of the control effect on heterogeneity was also analyzed. First, the total effect size of the 66 group experimental research with meta-analysis was high(ES = 1.35). Second, the effect size of independent variables was the highest at psychological exercise(ES = 2.18). The effect size by dependent variables was the highest in body(ES = 1.78), and it was found that social emotion, cognition, adaptive behavior, and communication all showed good effect sizes(ES > .8). Third, the effect size of the publication type showed a great effect in both the degree and the journal. We used Meta-Anova to explore the variables that can explain the heterogeneity of effect sizes. Variables that could be attributed to heterogeneity were independent variable R² = .23 and publication type R² = .03. In this study, we systematically analyzed the overall results of the previous studies by meta - analysis, objectively evaluated the effect size value of the studies, and suggested the research direction. 본 연구는 2008년 장애인 등에 대한 특수교육법 시행 후 발달지체유아를 대상으로 한 집단실험연구의 효과크기에 대한 메타분석을 통하여 과학적으로 종합하고 객관적인 결과를 도출하여 향후 연구방향성을 모색하는데 있다. 이를 위해 2008년부터 2018년 6월까지 국내 석⋅박사 학위 논문 및 학술지에 게재된 집단실험연구 논문의 전체효과크기(ES), 독립변인과 종속변인의 효과크기, 출판편향의효과크기와 이질성에 대한 조절효과크기를 분석하였다. 그 결과 첫째, 발달지체유아의 집단실험연구전체 효과크기는 값(ES)이 1.35로 높게 나타났다. 둘째, 독립변인의 효과크기는 심리운동이 2.18로가장 높았으며 교사 및 교수, 기억훈련, 놀이 및 운동, 교육 및 훈련 또한 .8 이상으로 효과가 큰 것으로 나타났다. 종속변인의 효과크기는 신체가 1.78로 가장 높았으며, 사회⋅정서, 인지, 적응행동, 의사소통 모두 .8이상으로 효과가 큰 것으로 나타났다. 셋째, 출판편향의 효과크기는 학위, 학술지모두 .8이상으로 효과가 크게 나타났다. 이와 같이 본 연구에서는 선행된 집단실험연구의 결과를 통합 분석하여 개별 연구들의 효과크기(ES) 값을 객관화하였고 향후 발달지체유아 연구의 신뢰성을 높이기 위한 연구의 방향성을 제언하였다.

This study makes use of meta-analysis to statistically integrate the quantitative results of individual research on the influence of fashion product attributes on purchase; in addition, this study utilizes the effect sizes of correlation coefficients. This study was based on 24 individual studies from January 2000 to March 2015. The meta-analysis analyzed 91 effect sizes and 24 studies and calculated the correlation coefficient effect sizes. A random effect model was employed for meta-analysis because the results for the homogeneity test indicated that the effect sizes of each research were heterogeneous. The analysis results are as follows. First, when the total effect sizes of the fashion product attributes that influence clothing purchase decisions were calculated as .256; this indicated that the effect size is slightly below the mid-sized level. Second, upon examining the effect sizes of the categorized fashion product attributes, the intrinsic attributes yielded .222, extrinsic factors yielded .235, and the compiled attributes yielded .420; this demonstrated that the compiled attributes have a larger effect size than individual attributes. Third, when they were measured by the characteristics of study targets, they were larger for a mixed-gender group than women as well as for ordinary citizens than university students. When the effect sizes were measured based on the characteristics of fashion products as suggested in the study, there were significant differences with respect to sportswear, followed by SPA brand clothing, general clothing, fashion accessories, and designer clothing. The cases where the clothing were purchased in non-retail stores were found to have a slightly larger effect size than those of offline retail stores when the effect sizes were measured based on purchase routes; however, the difference was not statistically significant. Next, an investigation of the trend of effect sizes based on published year via the meta regression analysis indicated slightly larger effect sizes as shown in more recent publications, but this was not statistically significant.

This study attempted to systematically evaluate the correlation effectiveness between self-handicapping and factors related to it by integrating empirical research findings on self-handicapping from studies conducted in Korea over a period of 21 years. Individual empirical studies conducted on the subject of self-handicapping from 2001 to 2021 were collected, and their results were analyzed through meta-analysis. Specifically, a total of 53 individual studies were selected for meta-analysis and analyzed using the CMA program to calculate the correlation effect size. The results were as follows: 1) The overall effect size of factors affecting self-handicapping was .277, indicating a moderate or higher effect size. 2) The effect size of factors related to self-handicapping, individual internal factors ESr= .280 and environmental factors ESr= .141 showed that individual internal factors are more related to self-handicapping than environmental factors. Among the internal factors, emotion showed the largest correlation effect size (ESr= .399), and among environmental factors, the teacher showed the largest correlation effect size (ESr= .180). 3) On calculating the effect size according to sub-categories of internal factors, it was found that academic self-concept (ESr= -.423) and expectancy-value (ESr= -.315) had large correlation effect sizes in motivation; in emotion, negative affect (ESr= .395) and positive affect (ESr= -.314) showed the largest effect sizes in that order; and in behavior, adaptation to school life (ESr= -.388) showed the largest effect size. In addition to this, in internal factors, self-esteem showed a large correlation effect size (ESr= -.371). Among environmental factors, social support from teacher showed the largest correlation effect size negatively (ESr= -.320). This study suggests a direction for subsequent studies by revealing the correlation effect sizes between self-handicapping and related factors by comprehensively synthesizing individual studies on the subject of self-handicapping. 본 연구는 약 20년간 국내에서 수행되어온 자기손상을 주제로 한 실증 연구논문들을 통합하여 자기손상과 관련 요인들과의 상관효과성을 체계적으로 검증하고자 하였다. 이를 위해 본 연구는 2001년부터 2021년까지 21년 동안 국내에서 자기손상을 주제로 수행된 개별 연구물들 중, 총 53편의 개별 연구물들을 CMA프로그램을 사용하여 효과크기를 산출하였다. 그 결과, 첫째, 자기손상에 영향을 미치는 요인들의 전체 효과크기는 .277로 중간 이상의 효과크기를 나타냈다. 둘째, 자기손상과 관련된 요인들을 크게 개인내적 요인과 환경 요인으로 분류하여 효과크기를 산출한 결과, 개인내적 요인은 ESr= .280, 환경 요인은 ESr= .0.141로 개인내적 요인이 환경 요인보다 자기손상과 더 관련성이 높은 것으로 나타났다. 개인내적 요인 중에는 정서가 가장 큰 효과크기를 나타냈으며(ESr= .399), 환경 요인 중에서는 교사가 큰 효과크기를 나타냈다(ESr= .180). 셋째, 개인내적 요인 하위 유목화에 따른 효과크기를 산출한 결과, 동기에서는 학업적 자기개념(ESr= -.423)과 기대-가치(ESr= -.315)가 큰 효과크기를 나타냈으며, 정서에서는 부정정서(ESr= .395)와 긍정정서(ESr= -.314)가 순서대로 큰 효과크기를 나타냈고, 행동에서는 학교생활적응(ESr= -.388)이, 기타 개인내적 요인에서는 자아존중감(ESr= -.371)이 큰 효과크기를 나타냈다. 환경 요인에서는 교사의 사회적 지지(ESr= -.320)가 큰 부적 효과크기를 보였다. 본 연구는 자기손상과 관련된 요인들 간의 관계를 밝힌 개별 연구들을 종합적으로 분석함으로써 자기손상 관련 요인들과 자기손상 간의 상관효과크기를 체계적으로 보여줌으로써 자기손상에 대한 후속연구에 방향을 제시하였는데 연구적 의의를 갖는다.
