Dental caries is biofilm induced disease throughout life and is recognized significant oral health problem. This article reviewed new trends in dental caries management by risk assessment, including history, protocol/guideline, and collaborated model. Dental caries prevention and treatment according to caries management by risk assessment (CAMBRA) model is patient-centered, risk-based, evidence-based practice. Team approach is necessary and clinician need to integrate science, practice and product. Dental hygienist take a important role in implementing CAMBRA. CAMBRA model could be incorporated into clinical dental hygiene education based on dental hygiene process of care as standard of dental hygiene practice and education. Dentist and dental hygienist able to provide scientific and ethical care managing dental caries by risk assessment.

Recently, the criteria for assessing industrial accidents have been replaced by the mortality rate. It was found that the number of deaths from excavation work was the highest among construction machinery. The risk assessment is being conducted, however the industrial accident mortality rate has not decreased. Accordingly, this study aims to provide the basic for the create of a risk assessment model specialized in construction work at excavator. It provides absolute value from the risk model which is capable of delivery the probability of a disaster. In addition, we provide a relative risk model that compares the risk through scores between detailed works. The relative risk model is combined by likelihood and severity; the likelihood indicates the frequency of accidents and the severity indicates seriousness of fatal accidents. A variable that reflects the conditions of the construction site was added to the risk assessment model based on past disaster cases. And using the concepts of probability and average, the risk assessment process was quantified and used as an objective indicator. Therefore, the model is expected to reduce disasters by raising the awareness of disasters.

The diagnostic and prognostic methods for generating 3 dimensional wind field were comparatively analyzed and 4 dimensional data assimilation (FDDA) technique by incorporating Automatic Weather System (AWS) into the prognostic methods was discussed for the urban scale air quality model. The A WS covered the urban scale grid distance of 10.6 km and 4.3 km in South Korea and Kyong-in region, respectively. This is representing that AWS for FDDA could be fairly well accommodated in prognostic model with the meso${\gamma}$~ microa scale (~5 km), indicating that the 3 dimensional wind field by FDDA technique could be a useful interpretative tool in urban area for the atmospheric environmental impact assessment.

This study proposes a model for railway safety assessment with which the safety of whole railway system can be evaluated. The purpose of the assessment model is to generate safety indicators which quantitatively represent the degree of railway safety. Safety indicators were proposed as three indicators according to their functions; accident indicators, safety management indicators, and safety culture indicators. This paper describes the first result on the safety target which will be a key starting point toward the development of safety assessment model. It is recommended that the safety target to be composed of several sub-targets are apportioned to constituent components. It is concluded that the classification of safety target has influence on deciding components or attributes that constitute each sub-indicators; accident indicators, safety management indicators, and safety culture indicators. Based on this study, a railway safety assessment model will be developed in the following study.

Daily solar radiation is essential for water resources planning and environmental impact assessment. However, radiation data is not commonly available in Korea other than in big cities, and there has been no direct measurement for rural areas where water resources planning and environmental impact assessment is usually most needed. In general, missing radiation data is estimated from nearby regional stations within a certain distance, and this study compared two dominant methods (modified Angstrom equation and transmittance interpolation method) at six stations in Nakdong River watershed area. Two methods shows a similar level of accuracy but the transmittance interpolation method is likely to be superior in that there is no need for any measurement element since the modified Angstrom equation require the sunshine hour measurement. This study will contribute to improve water resource and water quality management in Nakdong River watershed.

How to measure Quality Performance (QP) or excellence performance in organizations is very important for improving the quality of an organization's products and services. This paper takes Quality Function Deployment (QFD) as a useful tool to identify the key characteristics of quality performance and measure the influence factors on quality performance. Most national quality awards provide a framework of the criteria to show the essential elements of an organization's quality performance and get the Quality Performance Score (QPS) by self-assessment using the criteria. By means of these criteria, especially, the criteria of China Quality Award (CQA), a measurable indicator system for quality performance is set up. A four-phase QFD model of assessment for quality performance is developed. This QFD model not only presents the most important efforts for the deployment of the measurable indicators of quality performance, but also takes great advantage of evaluating the quality performance and obtaining the quality performance score. The measurable indicator hierarchy of quality performance is formed and its implementation method for assessment quality performance is described in this paper.

Managing the quantitative measurement of the data control activities in enterprise wide is important to secure management of data governance. However, research on data governance is limited to concept definitions and components, and data governance research on evaluation models is lacking. In this study, we developed a model of quantitative assessment for data governance including the assessment area, evaluation index and evaluation matrix. We also, proposed a method of developing the model of quantitative assessment for data governance. For this purpose, we used previous studies and expert opinion analysis such as the Delphi technique, KJ method in this paper. This study contributes to literature by developing a quantitative evaluation model for data governance at the early stage of the study. This paper can be used for the base line data in objective evidence of performance in the companies and agencies of operating data governance.

본 연구에서는 철도사고 위험분석 및 위험도 평가절차에 따라 철도건널목사고에 대한 정량적인 위험도평가를 위한 모델을 사건수목 및 고장수목 분석기법을 이용하여 개발하였다. 위험사건이 발생하여 인명피해로 결과하는 과정에서의 영향인자들을 분석하여 사고진전 시나리오를 구성하였으며, 고장수목분석(FTA, Fault Tree Analysis)을 이용하여 시나리오 경로별 발생확률을 산정하고, 사건수목분석(ETA, Event Tree Analysis)을 이용하여 심각도 값을 산정함으로써 이들의 조합으로 위험도를 산정하는 위험도 평가 모델을 제시하였다. 또한 실제발생한 위험도값과 개발모델을 이용하여 산정된 위험도값의 비교를 통하여 개발모델의 신뢰성 및 타당성을 검증하였다.

This study proposes a self-assessment model and its implementing procedure for the local industry promotion project, the purpose of which is to develop strategies for successful carrying-out of the project by diagnosing carrying capacities of its interested parties. The model, developed principally based on Eckes' $Q{\times}A=E$ Evaluation Model, was applied to 85 project-concerned persons which had been participated in the local industry promotion project from 2009 to 2011. Through the applicability test works of this model, its usefulness and importance for better implementation of the project was ascertained, especially to reflect cultural changes of project actors positively. The actors' recognition level of the project should be one of the critical factors for the successful implementation of the local industry promotion project. So, the higher understanding in the local industry promotion project, the more positive assessment in all respects of the project. Finally, it should be considered that the assessment results might differ for the same assessment standards from assessers' different perspectives.
