Purpose: The purpose of this study was to verify the validity and applicability of the Clinical Ladder System(CLS) Model for nurses and to suggest a model for nurses in general hospitals as well as tertiary hospitals. Methods: After refining questionnaires through focus group participation, a survey was carried out with 50 nurse managers and 500 staff nurses from 6 tertiary hospitals and 4 general hospitals. S-CVI and i-CVI for validity and applicability were calculated. Differences in validity and applicability by the type of hospitals and characteristics of respondents were analyzed using t-test and ANOVA. Results: S-CVI for validity and applicability of the CLS model were over 0.8 in two types of hospitals and the validity and applicability of the CLS model were confirmed. No differences were found in the total score for validity between the 2 types of hospitals, but in applicability, general hospitals had significantly lower applicability than tertiary hospitals. Some items showed difference according to characteristics of the respondents. CLS models were postulated based on the study results. Conclusion: The CLS model refined through this study can be used for nurses. In application, modifications are needed according to the conditions of each hospital.

This study is aimed at developing of the sustainable interface module for structural design. It is dealt with the Midas/Gen for analysis and design and Tekla Structures for Building Information Modeling. In this research, it is improved the applicability and function of the existing interface module developed by authors. Although model information was functionally well linked by the existing module in both directions, the applicability is limited due to the difference of attributes between structural analysis model and structural detail model. In this study, we analyzed the problems that occur in existing module. We have developed the interface module to solve the problems and improved the applicability of the existing module.

Soil properties, drain conditions and numerical analysis technique have great influence upon consolidation behavior. In relevant to the above described fact, this paper aims to examining the applicability of prediction model of consolidation as well as deformation characteristics for soft clayey foundation improved by sand drain. A case study for actual foundation of Kwangyang steel works was performed. Single drain consolidation model proposed by Hansbo and Biot's consolidation theory coupled with modified Cam-clay model developed during the research were employed for the FEM numerical analysis of the foundation. Both smear effect and drain capacity were taken into account for the analysis. Finally the applicability of the newly developed technique to the behavior of foundation composed of soft clay proved satisfactory.

This study presents a model and its implementation methodology assessing not only maturity but also applicability in order to increase the practical usage of open source software(OSS). Since this model measures applicability which can not be assessed by the previous models, it is able to support users in many ways when they introduce OSS for the first time, replace commercial software with OSS, and compare OSS with commercial software. For the purpose of design and implementation of this model, we presented a methodology with 7 phases and conducted a survey to evaluate the appropriateness and reliability of the model. In addition, we proved the practical usability of the model by providing a practical example assessing maturity and applicability of OSS in the area of the infra category on the basis of the methodology. In the future, not only general users but also officers in charge of informatization will be able to select optimal OSS by using this model for industrial application. Therefore, the result of this research is expected to greatly contribute to OSS promotion policy.

We verified the applicability of the developed universal model for the parameter estimation through the rainfall-runoff analysis at 16 watersheds. The existing parameter estimation equations derived from the restricted conditions sometimes, gave the meaningless results which cannot reflect the watershed characteristics and so have not widely used in the ungaged watershed. The values estimated from the developed universal model showed which are sensitive to variations of watershed characteristics. Wider applicability of SFM in ungaged watersheds is expected with the used of effective rainfall from CN method and the universal model.

Predictions of stream water quality require both estimation of pollutant loading from different sources and simulation of water quality processes in the stream. Nonpoint source pollution models are often employed for estimating pollutant loading in rural watersheds. In this study, a conjunctive application of SWAT model and WASP model was made and evaluated for its applicability based on the simulation results. Runoff and nutrient loading obtained from the SWAT model were used for generating input data for WASP model. The results showed that the simulated runoff was in good agreement with the observed data and indicated reasonable applicability. Loading for the water quality parameters predicted by WASP model also showed a reasonable agreement with the observed data. It is expected that stream water quality could be predicted by the coupled application of the two models, SWAT and WASP, in rural watersheds.

A detailed geometrical model of a Krško reactor core was developed using a Monte Carlo neutron transport code MCNP. The main goal of developing an MCNP core model is for it to be used in future research focused on ex-core calculations. A script called McCord was developed to generate MCNP input for an arbitrary fuel cycle configuration from the diffusion based core design package CORD-2, taking advantage of already available material and temperature data obtained in the nuclear core design process. The core model was used to calculate 3D power density profile inside the core. The applicability of the calculated power density distributions was tested by comparison to the CORD-2 calculations, which is regularly used for the nuclear core design calculation verification of the Krško core. For the hot zero power and hot full power states differences between MCNP and CORD-2 in the radial power density profile were <3%. When studying axial power density profiles the differences in axial offset were less than 2.3% for hot full power condition. To further confirm the applicability of the developed model, the measurements with in-core neutron detectors were compared to the calculations, where differences of 5% were observed.

Generally, the time history analysis among seismic response analyses of a structure needs more times than static analysis. Therefore the mechanical model of a structure has been used as a simple lumped parameter model in time history analysis. For the most cases, the simple mechanical model shows the similar results to that of detailed finite element model. so it is reasonable to use the simple mode] in preliminary analysis. In seismic design of liquid storage tank, such as LNG storage tank, the lumped parameter mode] also is being used in preliminary analysis, however sometimes shows the differences to the results of detailed finite element model. Therefore in this study, the dynamic characteristics between lumped parameter model and detailed finite model is compared for the variables such as height/diameter of liquid-storage tank and thickness of wall, then the applicability of beam mode] to the seismic response analysis are evaluated for some liquid storage tanks.

The applicability of a distributed rainfall-runoff model for large river basin flood forecasts is analyzed by applying the model to the Nakdong River basin. The spatially explicit hydrologic model was constructed and calibrated by the several storm events. The assimilation of the large scale Nakdong River basin were conducted by calibrating the sub-basin channel outflow, dam discharge in the basin rainfall-runoff model. The applicability of automatic and semi-automatic calibration methods was analyzed for real time calibrations. Further an ensemble distributed rainfall runoff model has been developed to measure the runoff hydrograph generated for any temporally-spatially varied rainfall events, also the runoff of basin can be forecast at any location as well. The results of distributed rainfall-runoff model are very useful for flood managements on the large scale basins. That offer facile, realistic management method for the avoiding the potential flooding impacts and provide a reference for the construct and developing of flood control facilities.

A fixed angle softened truss model has been developed in order to predict both shear strength and deformation of reinforced concrete members. The model takes into account the contribution of concrete by accuming the angle of cracks in the postcracking concrete that coincides with the reinforced concrete principal compressive angle determined by the applied stresses. Therefore, this model is capable of predicting the contribution of concrete from the govering equilibrium and compatibility equations including the shear stress and strain developed along concrete diagonal crack. However, the model has a limiting range to be applicable for reinforced concrete members. This research proposes a new algorthm of fixed angle softened truss model capable of removing the limitation of applicability. The proposed algorithm adopts a new conception of constitutive laws. The average normal stresses of concrete in the x- y- directions can be calculated by transforming the principal stresses of concrete. The proposed algorthm is verified by comparing to the test results.
