본 논문은 인지기능장애를 동반한 환자를 검사하고, 재활치료와 인지기능 평가를 하는데 사용될 수 있는 전자펜 기반의 시스템을 제안하고 있다. 제안된 시스템은 기존에 병원에서 널리 사용 중인 종이와 펜을 활용한 라인추종시험(Line tracing test; LTT)을 그대로 응용함으로써, 환자와 치료사가 거부감 없이 새로운 시스템을 적용할 수 있도록 하였다. 개발된 시스템의 정확성과 효과를 검증하기 위하여 성인 남녀 20명을 대상으로 시험한 결과, 전자펜을 활용한 측정치와 사람이 직접 측정한 측정치 간의 신뢰도가 0.90으로, 효과크기는 0.38로 평가되었으며 이는 전자펜을 활용한 검사 결과를 충분히 신뢰할 수 있음을 의미한다. 이와같이 신뢰성을 유지하는 반면, 검사 결과를 산출하는 시간에 있어서 사람이 직접 산출하는 경우 평균 48.2초가 소요되는데 반하여 전자펜을 기반으로 하는 방식의 경우 실시간으로 평가 결과가 기록되며 검사 종료 후 즉시(1초이내) 결과가 산출되기 때문에 시간 효율이 높음을 확인할 수 있다. 제안된 시스템은 파킨슨병, 심장마비 등으로 인한 뇌손상 환자의 인지기능장애 검사에 활용될 수 있다.

This paper analyzes three theories for land degradation assessment and internationl/domestic methods for land degradation monitoring and assessment. Under the guidance of absolute degradation thought, this paper proposes the technological framework for monitoring and appraising cultivated land degradation based on the 3S technique. We can apply 3S technique and analyze the nature, the environmental, the social, and the economic elements which influence the land utilization and degradation synthetically, to set up the indicator system of the cultivated land degradation monitoring and assessment based on 3S technique; to propose the degradation information extraction methods based on 3S technique; to create the quantitative assessment model and method for land degradation; to analyze the ecological environment response of land use and degradation quantitatively; and to propose the measure, policy and suggestion for solving the land degradation problem from the point of view of land utilization.

교사의 교육과정에 대한 이해 정도에 따라 교수 학습 방법에 상당한 차이가 존재할 수 있으며 평가 문항은 이러한 차이를 반영하는 대표적 산물 중 하나이다. 그러므로 지필평가 문항 분석을 통하여 교사의 교육과정에 대한 이해도가 지필평가에 어떻게 반영되고 있는가에 대한 실태 연구가 필요하다. 본 연구에서는 2009 개정 수학과 교육과정에 기반하여 중간고사와 기말고사로 출제된 '미적분I' 219개 검사지에 수록된 문항 중 '수열의 극한'을 내용 영역으로 하는 문항을 중심으로 변화된 교육과정이 학교 현장의 지필평가에서 어떻게 반영되고 있는지를 분석하였다. 분석 결과를 토대로 지필평가에서 나타난 문제점을 확인하고, 교육과정 개정 이후 새로운 교육과정의 안정적 안착을 위하여 반드시 동반되어야 할 교육정책 관련 시사점을 도출하고자 하였다.

The loss prediction and assessment during extreme events such as wind hazards is always crucial for the group low-rise residential buildings. This paper analyses the effect of variation in building density on wind-induced loss for low-rise buildings and proposes a loss assessment method consequently. It is based on the damage matrices of the building envelope structures and the main load-bearing structure, which includes the influence factors such as structure type, preservation degree, building density, and interaction between different envelope components. Accordingly, based on field investigation and engineering experience, this study establishes a relevant building direct economic loss assessment model. Finally, the authors develop the Typhoon Disaster Management System to apply this loss assessment methodology to practice.

The collision problem is one of the design factors that must be carefully considered for the risk of collision occurring during the operation of ships and offshore structures. This paper presents the main results of the ship collision study, and its main goal is to analyze potential crash scenarios that may occur in the FLNG (Floating Liquefied Natural Gas) considering the likelihood and outcome. Consideration being given to vessels visiting the FLNG and surrounding vessels navigating around, such as functionally supported vessels and offloading carriers. The scope includes vessels visiting the FLNG facility such as in-field support vessels and off-loading carriers, as well as third party passing vessels. In this study, based on QRA (quantitative risk assessment), basic research methods and information on collision are provided. Based on the assumptions and methodologies documented in this study, it has been possible to clarify the frequency of collision and the damage category according to the type of visiting ship. Based on these results, the risk assessment results related to the collision have been derived.

Portfolios have gained attention in medical education as a tool for promoting student learning and assessment since Miller's call for better tools for assessing students' clinical competencies. This paper reviews the development and use of e-portfolios for promoting learning and assessment in medical schools, both domestically in Korea and internationally. This review finds that some specific features need to be incorporated into e-portfolio systems for medical education and that these systems can be used to manage student learning in clinical clerkships and to support competency-based assessment. The author asserts that the e-portfolio is key to promoting competency-based education and suggests practical tips for effective development and use of e-portfolios in Korean medical schools.

This paper seeks for the set-up plan in the reasonable target area of environmental assessment. Domestically, the target area of environmental assessment is set up by the adjustment of opinion collection about the assessment scope result of an environmental factor. In a foreign country, the boundary of the target area for a development project is established with the environmental, economical, and social viewpoint based on the standard for significantly environmental impact. Based on the analysis of the present condition at home and abroad, the first set-up plan for the reasonable target area of environmental assessment is the preparation of the detailed term definition related to the target area of environmental assessment. The second is the arrangement of the judgement standard for significantly environmental impact. The quantitative assesment item can apply the present standard or regulation, and the qualitative assessment item can establish the standard based on factual and objective data. The last is the preparation of the reference material or the guideline for deciding the initial target area by the judgement standard and determining the final target area by opinion collection in the stage of scoping.

Purpose: The purpose of this paper is to study quantitative risk grade assessment for objective government quality assurance activities based on risk management in initial mass production for weapon systems. Methods: The Defense quality management regulations and foreign risk assessment documents are referred to analyze problems performing quality assurance actives. The failure rate data, maintainability and cost of products have been studied to quantify the risk Likelihood and impact. The analyzed data were classified as risk grade assessment through K-means Cluster Analysis method. Results: Results show that a proposed method can objectively evaluate risk grade. The analyzed results are clustered into three levels such as high, middle and low. Two products are allocated high, eleven low and seven middle. Conclusion: In this paper, quantitative risk grade assessment methods were presented by analyzing risk ratings based on objective data. The findings showed that the methods would be effective for initial mass production for weapon systems.
