This study provides an in-depth comparison and analysis of various risk assessment models widely used in modern industries, and proposes the most suitable model for risk assessment of offshore wind power in Korea. The assessment models were selected by considering various factors such as the purpose of risk assessment, stakeholder requirements, and characteristics of offshore wind power. We also emphasized the importance of using different risk assessment models in combination in situations of high uncertainty. To systematize the combination of risk assessment models, we used systems engineering which is effective to develop a new system. Systems engineering was used to define the complete, traceable functions from site requirements, and model-based systems engineering was used to manage the design information from requirements to detailed functions in a single model. The developed risk assessment module provide automatic conversion between risk assessment models to enable risk assessment suitable for offshore wind power. The functionality and usability of the offshore wind risk assessment module were verified by the evaluation of three wind power experts.

The purpose of this study is to develop the model of course evaluation design for CEA(Course-Embedded Assessment), which is focused on course level for assessment reliability. This study was conducted by the process of model development and validation according to Richey & Klein(2007)'s model development methodology. The model of this study was comprised with the three steps of learning objectives based on course outcome, assessment design and goal achievement analysis of course, which were explained by specific design principles. Also, this model was validated by two steps, which one was on the inner validation and the other was the outer validation(Richey & Klein, 2007). Considerations for designing the model of course evaluation have been suggested and a few implications were discussed.

본 논문에서는 착신효과(Recency Effect)와 버스트 패킷 손실 모델을 적용한 유비쿼터스 환경에 적합한 VoIP 통화품질 측정모델을 제안하였다. 이 측정모델을 통하여, 기존의 모델에서는 구현할 수 없었던 시간의 흐름에 따른 통화품질의 측정이 가능해지며, 또한 버스트 패킷 손실 모델을 적용하여, 현재의 네트워크 환경에 부합시켜 이전 모델보다 정교하고 신뢰성 있는 측정을 가능하도록 하게 하였다.

This paper presents the probabilistic-based assessment of composite steel-concrete structures through an innovative framework. This framework combines model identification and reliability assessment procedures. The paper starts by describing current structural assessment algorithms and the most relevant uncertainty sources. The developed model identification algorithm is then presented. During this procedure, the model parameters are automatically adjusted, so that the numerical results best fit the experimental data. Modelling and measurement errors are respectively incorporated in this algorithm. The reliability assessment procedure aims to assess the structure performance, considering randomness in model parameters. Since monitoring and characterization tests are common measures to control and acquire information about those parameters, a Bayesian inference procedure is incorporated to update the reliability assessment. The framework is then tested with a set of composite steel-concrete beams, which behavior is complex. The experimental tests, as well as the developed numerical model and the obtained results from the proposed framework, are respectively present.

This paper compared the consistency of the Environment Stress(ES) model and the Potential Risk Assessment Model (PARK model, which was developed based on a Korean mariner risk perception) for the Busan adjacent waterway. Evaluation of accuracy and comparison of these two models have been made by Vessel Traffic Service (VTS) officers in the Busan VTS Centre. The assessment results of Busan waterway show that the PARK model is more consistent than the ES model as follows. (1) The difference between assessment results applying ES model and PARK model with risk degree of VTSOs were 34% and 5% respectively in six typical traffic situations. (2) The assessment using PARK model is more suitable and identical with the VTSOs opinion in his or her duty time.

The competitiveness of modern organizations highly depends upon organizational competencies rather than individual competencies. However, most of previous studies on project success focused on individual competencies, such as project manager's competency and leadership. Even though there are some assessment models for the organizational project competencies, they are limited in specific organizations and industries. Furthermore, it is difficult to apply them to domestic companies, especially to small and medium enterprises because some assessment items are inappropriate for them. The purpose of this study is to propose an organizational project competency assessment model that is suitable for evaluating small and medium enterprises. First, the assessment areas and items for each area are determined through extensive investigation of previous models including OPM3, CMMI, and PMBOK. Next, the weights of assessment areas and items are decided by AHP analysis of experts response in the field of the project management. Finally, a project competency assessment model with assessment sheets is proposed. The model proposed in this study might support managers of small and medium enterprises to find pros and cons of project competencies and to establish improvement plans.

The goals of this study were to development Natural Ecosystem Value Assessment Model, to suggest the practical applicability of the Natural Ecosystem value assessment for development areas, and to assess natural ecosystem quantitatively using GIS. The Model can evaluate Natural Ecosystem Value between before and after land developments. To select indicators for the model, we conducted the literature reviews. and six indicators and the standard of evaluation had been developed through the expert interviews and literature reviews. the relative importance of the evaluation index throught two times expert questionnaires was found out. the Natural Ecosystem Value Assessment Model has been established, The results demonstrate that although the suggested six indicators are arranged by priority, to maintain quantitative and qualitative the natural ecosystem value, all indicators are desirable to be maintained complementarily. The findings of this study suggest that the natural ecosystem value assessment model appears to be effective an assessment for damaged natural environment value and possible to assign a score value. Also, this model can be applied to research areas and has implications to help maintain the natural ecosystem in land development districts.

Recently, the assessment of a bank efficiency focusing on its branches has been conceived as important in developing a competitive strategy. DEA (Data Envelopment Analysis) model can be employed as an effective analysis model for such an assessment. Therefore, this paper proposes an analysis process using DEA model to conduct an efficiency assessment of bank branches. The proposed process includes a segmentation of branches considering their competitive environment and strategy for target market : this approach can help to develop effective strategies for each group of branches. The proposed DEA model can analyze efficiency in terms of not only cost but also marketing. Finally, a real case is analyzed, demonstrating the effectiveness of the proposed model and process.

Type R fire alarm is required intelligent buildings and height buildings which was based on automatic system. But in Korea, maintenance of fire alarm system is very poor. In this study, we developed assessment model for the type R fire alarm system which was assessed by using 96 checklist items. The assessment model was tested through the actual 4 buildings with type R fire alarm system. It is shown that present model can be applied for the assessment of all buildings through the examination of the suitability of assessment model by actual assessment. Also, it was made easily fire manager to carry out checklist for type R fire alarm system in buildings.
