  • Purpose: The purpose of this study was to explore the experiences of nursing students in Korea who used concept mapping for understanding pathophysiology. Methods: The data were collected using an open-ended questionnaire from 83 sophomore nursing students after studying concept mapping in pathophysiology class. Each group consisted of five nursing students submitting four concept maps regarding cell injury, inflammation, infection, and neoplasm. After familiarity with concept mapping, the participants wrote their experiences anonymously on sheets of paper. The submitted materials were analyzed via qualitative content analysis. Results: The collected materials were classified into 3 themes, 8 categories, and 18 subcategories. Three themes emerged: (1) awareness of capabilities, (2) difficulties of completion, and (3) benefits of application. Conclusion: The study revealed that participants experienced self-capabilities, and the difficulties and benefits of concept mapping. Concept mapping also provided the opportunity for nursing students to realize communication skill improvement by active group discussion within a group.

  • Motivation of this study is based on these two aspects: geologic uses of ASTER and application scheme of Spectral Mixture Analysis. This study aims at geologic mapping for mineral exploration using ASTER and LANDSAT 7 ETM+ at Mongolian plateau region by SMA. After basic pre-processing such as the normalization, geometric corrections and calibration of reflectance, related to endmembers selection and spectral signature deviation, both methods using spectral library and using PPI(Pixel Purity Index) are performed and compared on a given task. Based on these schemes, SMA is performed using LANDSAT 7 ETM+ and ASTER image. As the results, fraction map showing geologic rock types are enough to meet purposes such as geologic mapping and mineral potential mapping in the case of both uses of these different types of remotely sensed images. It concluded that this approach based on SMA with LANDSAT and ASTER is regarded as one of effective schemes for geologic remote sensing.

  • Constructing a geo-spatial database of Graphic Information Systems(GIS) in various applications is suffering from the difficulty of data acquisition, which is labor-intensive and time consuming. In order to provide the spatial data rapidly and accurately, 4S-Van, a prototype mobile mapping system, has been developed. This paper presents a novel approach for an analysis for Mobile Mapping Systems. Furthermore, we discuss the accuracy of measurements using images acquired from the 4S-Van. The first part of this paper introduces accuracies of other mobile mapping systems. Then, we describe main features of the 4S-Van and our proposed method for an analysis accuracies, which can be applicable to other mobile mapping systems. The last part of paper concludes with a summary and our suggestions for implementation of mobile mapping system.

  • The purpose of this paper is twofold. On the one hand it takes issue with Engstrom's claim that conceptual metaphors are propositional; on the other, it aims to demonstrate that the mathematical term 'mapping' is inappropriate for the analysis of metaphors. To my mind, the propositional analysis of metaphors, a wrong analysis for that matter, originates in the notion 'mapping' I argue that partial 'mapping' between propositional meanings and metaphorical meanings is either mental or psychological, with no concomitant 'truth' value. When concept metaphors represent propositionality, they lose metaphoricity; when they obtain metaphoricity, they are free of propositionality. The mathematical terms 'mapping' and 'proposition,' it is stressed, should be avoided in the analysis of concept metaphors like 'A is B' because they are confusing when applied to linguistic expression. 1 suggest that the term 'mapping' be replaced by phrases such as 'interaction between two domains,' projection from source-domain to target domain,' or 'understanding the properties of two domains between A and B,' etc. This would amount to proposing a pragmatic or cognitive theory of metaphor.

  • Mapping is a useful tool in the magnetic field analysis and design. In some specific research area, such as the nuclear magnetic resonance (NMR) or the magnetic resonance imaging (MRI), it is important to map the magnetic field in the interesting space with high accuracy. In this paper, an indirect mapping method in the center volume of an air-core solenoid is presented, based on the solution of the Laplace's equation for the field. Through the mathematical analysis on the mapping calculation, we know that the condition number of the matrix, generated by the measurement points, can greatly affect the error of mapping result. Two different arrangement methods of the measurement points in field mapping are described in this paper: helical cylindrical line (HCL) method and parallel cylindrical line (PCL) method. According to the condition number, the HCL method is recommended to measure the field components using one probe. As a simple example, we mapped the magnetic fields in a MRI main magnet system. Comparing the results in the different methods, it is feasible and convenient to apply the condition number to reduce the error in the field mapping calculation. Finally, some guidelines were presented for the magnetic field mapping in the center volume of the air-core solenoid.

  • GIS 기반의 다기준 의사결정분석에서 공간현상을 제대로 재현할 수 있는 평가기준도를 작성하는 것은 정확하고 합리적인 적지분석 결과를 도출하기 위한 중요한 작업이다. 적지 분석 과정에서 행정 구역 자료를 이용한 평가 기준도가 널리 사용되고 있지만 아직까지 dasymetric mapping 방법을 이용하여 평가 기준도를 제작할 수 있는 방법에 대한 연구는 없었다. 본 연구에서는 공간 단위로 집계된 사회경제적 속성 값을 세부 공간 단위로 재할당하는 dasymetric mapping 기법을 활용하여 다기준 의사결정분석에 필요한 평가기준도를 작성하는 방법을 제안하였다. 본 연구에서 제안한 방법을 산업입지 분석에 적용한 결과, 노동력 평가기준도, 기존 도시와의 거리 평가기준도를 제작하여 속성의 공간 분포 패턴을 세부 공간단위로 재현할 수 있었다. 또한 다기준 의사결정분석 과정에 적용되어 산업입지 후보지에 대한 분석 결과를 도출하였다.

  • The purpose of this study was to evaluate elementary students' environmental mapping following an environmental literacy degree. For this purpose, 34 elementary students of the 5th grade in Daejeon were used as a sample, and their environmental literacy(EL) by 'environmental literacy inventory(ELI)' was assessed. In the end, the correlation between EL and 'Environmental Mapping' was analyzed. The major findings of this study were as follows: 1) 5th grade elementary school students have a high level of conceptual recognition in regard to environmental issues and problems but they have low level of environmental behavioral function; 2) in the correlational analysis of environmental Mapping assessment and EL degree have significant correlation at p<.01 ; 3) environmental issue knowledge and environmental susceptibility have significant correlation in environmental Mapping and p<.01; 4) in the correlation analysis of environmental Mapping assessment and environmental target level, fundamental elements and conceptual recognition have significant correlation at p<.01 and environmental behavior and function on environment have significant correlation at p<.05.

  • 이 연구에서는 비유를 사용한 반응 속도 개념 학습에서 유발되는 학생들의 대응 오류를 조사하고, 비유 표현 방식에 따라 비교하였다. 고등학교 1학년 학생 418명을 '농도와 반응 속도' 및 '온도와 반응 속도'의 목표 개념과 비유물의 글 또는 글과 그림 형태의 표현방식에 따라 4집단으로 배치하였다. 각 집단에 해당하는 비유 수업을 한 후, 대응 관계 이해도 검사를 실시하였다. 연구 결과, 과잉 대응, 인위적 대응, 대응 불이행, 무분별한 대응, 부적절한 대응, 표면적 속성 대응, 비유물 속성 보유, 불가능한 대응의 8가지 대응 오류 유형이 나타났다. 또한, 비유 표현 방식과 목표 개념의 속성에 따라 학생들이 범하는 대응 오류 유형의 빈도가 다른 양상을 보였다. 이에 대한 교육학적 함의를 논의하였다.

  • This study was carried out to construct mapping population and to evaluate the methods involved, including polymorphic DNA marker system and appropriate statistical analysis. As an initial step to establish chicken genome mapping project, White Leghorn (WL) and Korean Ogol chicken (KOC) were used for generating backcross population. From 8 initial parents, total 280 backcross progenies were obtained and 40 were used for genotyping and linkage analysis. For development of novel polymorphic markers for KOC, Random Amplified Polymorphic DNA (RAPD) markers specific for this chicken line were generated. Also included in this study were six microsatellite markers from East Lansing map as reference loci. For segregation analysis, 15 RAPD markers and 6 microsatellites were used to genotype the backcross population. Among the RAPD markers that we developed, 2 pairs of markers were identified to be linked and another 4 RAPD markers showed linkage with microsatellites of known map. In summary, this study showed that our backcross population generated from the mating of KOC to WL serves as a valuable genetic resource for genotyping. Furthermore, RAPD markers are proved to be valuable in linkage mapping analysis.
