Next, a field test conducted scale reliability construct validity 133 organizational members from Professional Baseball League (KPBL). findings indicate that successfully translated, items maintained same...
Autism is a developmental disorder which affects growing number of children worldwide. Since the was first discovered by Leo Kanner almost seven decades ago there has been lot research trying to unravel this otherwise esoteric disorder. That contributed better understanding disorder, shifting conceptualisations as well changing professionals' and families perceptions attitudes towards Together, these changes have helped promote outcomes among with autism. This study designed examine...

Abstract Most runoff analyses using a grid‐based distributed model use one parameter group calibrated at the outlet of watershed, instead dividing watershed into subwatersheds. Significant differences between observed value and simulation result subwatersheds can occur if just is used in all that have different hydrological characteristics from each other. Therefore, to improve results within every subwatershed needs be reflect subwatershed. In this study, groups were set up for or two sites...
The purpose of our quasi-experimental study was to examine the impact Girls on Run (GOTR) program multidimensional self-concept and attitudes toward fat. Young girls ( N = 21) participated in a 12-week running designed increase their ability, self-esteem, and, general, emotional, social, mental well-being. It hypothesized that would experience favorable changes global appearance, peer, physical, self-concepts overall RM-ANOVA examining for pre post differences significant, F (13, 8) 26.46, p...
This study identifies the descriptive cultural profiles of select American Triple-A Baseball (TAB) organisations by size, geographic location, wining percentage and average annual attendance using Competing Values Framework (CVF). In this study, an investigation types (clan, adhocracy, market hierarchical) suggests that within TAB place more emphasis on culture, which has internal focus, centralised structure goal achievement clan culture in terms cohesion trust. There was pattern group...
The hydrological model assessment and development (hydromad) modeling package is an R-based that can be applied to simulate models optimize parameters. As the hydromad incompatible with outside package, parameters of such cannot directly optimized. Hence, we proposed a method optimizing hydrological-model by combining executable (EXE) file shuffled complex evolution (SCE) algorithm provided package. A physically based, spatially distributed, grid-based rainfall–runoff (GRM) was employed. By...
This study aimed to assess the suitability of parameters a physically based, distributed, grid-based rainfall-runoff model. We analyzed parameter sensitivity with dataset eight rainfall events that occurred in two catchments South Korea, using Sobol’ method. Parameters identified as sensitive responded adequately scale and objective functions employed. Parameter varied depending on scale, even same catchment. Interestingly, for event causing considerable runoff, related initial soil...
The choice of the computational time step (dt) value and method for setting dt can have a bearing on accuracy performance simulation, this effect has not been comprehensively researched across different simulation conditions. In study, effects fixed (FTS) automatic (ATS) simulated runoff distributed rainfall–runoff model were compared. results revealed that ATS had less peak flow variability than FTS virtual catchment. method, difference in more impact other factors such as differences...
The purpose of this study was to examine the effect two major communication channels (e.g., TV and internet) on three factors sponsorship effectiveness, brand awareness, event-sponsor fit, purchase intention in Super Bowl 2008. results revealed that television a dominant medium for participants obtain information Bowl. Furthermore, use both activities will be more effective increasing effectiveness than using one channel. Finally, event interest, fit were identified as influencing consumers’...
본 연구의 목적은 LISFLOOD 모형을 이용하여 범람해석을 수행하고, 그 결과를 FLUMEN 모형에 의해 작성된 홍수범람도와 비교함으로써 국내하천에 대한 모형의 적용성을 평가하는 것이다. 이를 위해서 파제 시나리오를 작성하여 이용한 범람해석에 적용하였으며, 시나리오별 범람해석 평가하였다. 결과, 홍수범람도와의 각 구간별 범람면적의 상대오차가 0.2% ~ 42% 정도로 지점에 따라서 다소 상이한 나타내었다. 그러나 홍수위험지도 제작방법과 같이 시나리오의 중첩하여 두 최대 범람면적에서는 약 1.2%의 상대오차를 보임으로써 서로 유사한 한편 모형은 입력자료의 구축이 용이한 격자형태의 DEM과 상류단 경계조건인 수문곡선만을 활용하여 할 수 있으며, 소요되는 시간이 모형보다 짧은 것으로 나타났다. 그러므로 신속한 범람해석이 필요한 지역에 대해서는 활용이 가능할 판단된다. The purpose of this study is to simulate inundation and...
Harmonized World Soil Database (HWSD) including the global soil information has been implemented to runoff analysis in many watersheds of world. However, its accuracy can be a critical issue modeling because limitation low resolution reflecting physical properties watershed. Accordingly, this study attempted assess effect HWSD by comparing parameters rainfall-runoff model using with detailed map. For this, Grid based Rainfall-runoff Model (GRM) was employed Hyangseok The results showed that...
본 연구는 레이더 강우와 분포형 수문모형의 공간해상도가 매개변수 추정 및 강우-유출 모의에 미치는 영향을 분석하였다. 강우는 비슬산 S밴드 이중편파 강우레이더에서 2012년 관측된 강우사상을 대상으로, R-KDP, R-Z, R-ZDR의 관계식에 의해 추정된 강우를 지상관측 비교하였다. 세 가지 강우 추정식에 의한 지상 관측 비교 시 유역 평균에 대해서는 모두 높은 일치도를 보였으며, 이는 강우에 대한 보정의 영향으로 판단되었다. 그 중에서도 R-KDP에 강우가 비교적 정확도를 이를 모형의 입력자료로 적용하였다. 모형으로는 GRM (grid based rainfall-runoff model) 모형을 이용하여, 낙동강 수계 금호강 유역을 200m, 500m, 1000m의 공간해상도로 입력자료를 구축하였다. 또한, 범용 최적화 모형인 PEST(model independent parameter estimation tool)로 초기 포화도, 지표면 조도계수 토양 투수계수의 보정계수를...
우리나라의 산사태는 여름철 집중호우 시에 주로 발생하며, 강우는 산사태 발생에 결정적 영향을 미치는 요소이다. 본 연구에서는 산악지역에서 국지적으로 발생하는 산사태의 예측을 위한 레이더 강우자료의 활용성을 평가하였다. 2006년 7월에 발생한 인제지역 산사태를 대상으로 자료를 이용하여 유역내 강우 공간분포의 시간적 변화를 분석하였으며, 발생지와 발생 기간에서의 강우특성을 연구결과 강우장을 이용하는 것은 기존의 지점강우를 방법에 비해 국부적으로 발생할 수 있는 정밀하게 예측할 것으로 나타났다. Landslide in Korea occurs generally summer, and rainfall is a major factor to trigger landslides. This study evaluates the applicability of radar estimate landslide locally mountainous area. Temporal changes spatial...
이 연구의 목적은 대학 스포츠 팀 조직문화의 관찰을 통해 문화적 이해와 특징을 도출하는데 그 목적이 있다. 구체적으로는 관찰단위를 하위문화로 적용하여 강도와 유형의 다양성 및 핵심적 가치의 유사성을 도출하였다. 이를 위해 네 가지 조직문화 유형(자율, 관계, 성과, 변화)과 여섯 하위요인(분위기, 리더십, 의사소통, 의사결정, 팀워크, 목표)을 이용하여 다섯 차원(전체, 성별, 학년, 종목, 지역) 위계적 분석을 실시한 결과(n=580), 아래와 같은 결과를 첫째, 국내대학 스포츠팀 조직문화는 전체적 접근을 포함한 접근에서 성과와 인간관계에 대부분 중심을 두고 있는 것으로 나타났다. 둘째, 하위요인 중 분위기, 리더십의 경우 강조가 되는 나타났으나 의사결정과 목표는 상대적으로 강도가 낮은 이상의 연구결과를 토대로 학술적, 실무적 시사점을 논의하였다.
