국내 원자력 방사선 산업의 높은 성장과 전문 인력 수요의 증가는 기술 발전 단계관점에서 기술 공학자 혹은 중간기술자의 수요 확대를 가져왔다. 그러나 원자력 방사선 기술의 발전과 이용에 비해 전문인력 양성 교육기관은 빈약한 실정이다. 산업체에서 가장 필요로 하는 인력은 초중급 기술인력으로 이들을 양성할 교육기관이 필요하며 이들의 교육 수요를 만족시켜줄 가장 유리한 교육기관은 전문대학이라 하겠다. 따라서 현재 의료분야로 편중된 우리나라의 전문대학방사선과 교육과정을 산업체에서도 필요로 하는 교육과정을 개발하고자 한다. 연구개발의 내용과 그 범위는 크게 4가지로 구분하여 연구를 수행하였다. 첫 번째, 교육과정 시행의 대상인 방사선 산업체 관련 인력환경 기초 조사를 시행하였으며, 이를 위해 세부 시행 업무로서 국내의 방사선 산업체 종사자, 전문대학 방사선과 재학생과 교수를 대상으로 설문조사 및 분석을 하였다. 두 번째, 교육과정 개발에 필요한 기초 자료로서 국내외 방사선 관련 대학들의 사례를 통해 교육과정을 분석하였다. 또 이를 위해 국내, 일본, 미국의 방사선 관련 대학의 교육과정을 조사 및 분석하였다. 세 번째, 방사선 산업에 필요한 기초 과학 교과목과 방사선 전공 교과목을 개발하였다. 이 과정에서는 미국과 한국의 공학교육 인증원에서 제안하고 있는 원자력, 방사선 관련 교육 프로그램 지침을 참고로 하였다. 네 번째로 정규 교육과정에 필요한 교과목 즉 선택형 교과목을 개발하였는데, 여기에는 교과목 운영에 필요한 교육과정 개발과 정규 교육과정 이외의 심화과정 및 부전공제 운영 모델의 개발이 포함되었다. 연구의 핵심 결과는 방사선 산업체 업무 분야에 적합한 선택형 세부 교육과정을 제안하였는데, 각 대학의 특성과 교육 목표에 따라 달라질 수 있다. 첫 번째는 업무분야별 세부교육과정으로, 방사선 이용분야에 적합한 교과목과 방사선 안전관리 분야에 적합한 교과목을, 두 번째로 업체 유형별 세부교육과정으로 제조업체에 필요한 교과목, 비파괴검사업체에서 필요한 교과목, 판매기관에서 필요한 교과목, 그리고 연구소에서 필요한 교과목을 선정하였다. 또한 이러한 교과목을 시행하기 위하여 교과과정 2가지 운영 모델을 제안하였는데, 첫째는 현재 전문대학 방사선과 3년 과정에서 의료분야 전공과 산업분야전공 별로 전공제를 실시하는 방법과 둘째로, 전문대학을 졸업 후 심화과정(1년 과정)에서 산업방사선을 전공하도록 하는 방법이다. 운영모델을 좀더 효과적으로 운영하기 위해서는 보다 심도 있는 학제 연구와 더불어 교재의 개발이 전제되어야 하며, 교과운영에 필요한 교수인력, 실습공간, 기자재 등의 재정의 확보 역시 해결되어야 할 문제이다.

This paper presents quantitative analysis of a training system based on an unstable platform and a visual interactive system for improving sense of equilibrium. The training system consists of an unstable platform, a force plate, a safety harness, a monitoring device, and a personal-computer. To confirm the effects of the training system, fifteen young volunteers and five elderly volunteers went through a series of balance training using the system. During the training, we measured relevant parameters such as the time a subject maintain his or her center of pressure on a target, the time a subject moves his or her center of pressure to the target, and the mean absolute deviation of the trace before and after training with this system and training programs to evaluate the effects of the training. The results showed that the training system can successfully assess the gradual improvement of the postural control capability of the subject in the system and showed a possibility of improving balance of the subject. Moreover, the significant improvement in the postural capability of the elderly subject suggests that elderly subjects can benefit more from the training using the system for the improvement of sense of equilibrium.

This study investigated the impact of entry level of mathematics subject knowledge on student teachers' mathematics pedagogical content knowledge development and performance in mathematics teaching practice. The sample consisted of 24 mathematics student teachers, 12 of whom passed A-Level mathematics and 12 of whom only passed O-level mathematics. They were all studying in a 4-year bachelor of education (Honours/Primary) programme; they were either majoring or minoring in mathematics. Results showed that student teachers' entry-level mathematics subject knowledge is not related to their mathematics pedagogical content knowledge development or their mathematics teaching performance. These findings may lead society to consider whether student teachers who have passed O-level mathematics are already eligible to be trained as professional primary mathematics teachers. As a consequence, this study raises the issues of how to develop student teachers' mathematics pedagogical content knowledge and whether we need to restructure our bachelor of education (Primary) programmes' curriculum in teacher professionalism.

This paper proposes a method for human identification using teeth contours extracted from dental images that are captured from the frontal views of subjects each of who opens his or her mouth slightly. Each dental image has a black-colored region containing the subject's teeth contours which are usually different from subject to subject. This means that this black-colored region has bio-mimetic information useful for human identification. The basic idea of the method is to extract the upper and lower teeth contours from the dental image of each subject and to encode their geometric patterns using a back-propagation neural network model. After acquiring 400 teeth images form 10 university students, we used 300 images for the training data of the neural network model and 100 images for its verification. Experimental results have shown that the proposed neural network-based method can be used as an alternative solution for identification among a small group of humans with a low cost and simple setup.

Recently, shape analysis of human organs has achieved much attention, owing to its potential to localize structural abnormalities. For a group-wise shape analysis, it is important to accurately restore the shape of a target structure in each subject and to build the inter-subject shape correspondences. To accomplish this, we propose a shape modeling method based on the Laplacian deformation framework. We deform a template model of a target structure in the segmented images while restoring subject-specific shape features by using Laplacian surface representation. In order to build the inter-subject shape correspondences, we implemented the progressive weighting scheme for adaptively controlling the rigidity parameter of the deformable model. This weighting scheme helps to preserve the relative distance between each point in the template model as much as possible during model deformation. This area-preserving deformation allows each point of the template model to be located at an anatomically consistent position in the target structure. Another advantage of our method is its application to human organs of non-spherical topology. We present the experiments for evaluating the robustness of shape modeling against large variations in shape and size with the synthetic sets of the second cervical vertebrae (C2), which has a complex shape with holes.

The purpose of this study is to confirm the impact of noise on subject accomplishment as well as physical/mental load, and evaluates the effects of noise-masking and earplug. 15 college students participate in the test, and the comparison is performed by executing four projects according to conditional categories of noise environments; control condition, noise condition, earplug condition, and noise-masking condition. Noise in the field site of the H manufacturer was used as the noise source, the general job aptitude test which consist of linguistic ability, math ability, perception ability, reasoning ability was used as the task of this project. To estimate physical/mental load evaluation, we used the heart rate R-R interval, Criteria flicker fusion frequency(CFF) and measured NASA-TLX workload for subjective evaluation. As the research outcome, it is shown that there is a meaningful difference for the project task score, dropping rate of CFF, the heart rate, and NASA-TLX subjective evaluation score according to conditions of noise environment. Therefore, the impact of noise on capability of subject accomplishment as well as physical/mental load was confirmed along with the effects of using earplug and noise-masking.

This study suggests an alternative to the conventional collaborative filtering method for predicting consumer choice, using case-based reasoning. The algorithm of case-based reasoning determines the similarity between the alternative sets that each subject chooses. Case-based reasoning uses the inverse of the normalized Euclidian distance as a similarity measurement. This normalized distance is calculated by the ratio of difference between each attribute level relative to the maximum range between the lowest and highest level. The alternative case-based reasoning based on similarity predicts a target subject's choice by applying the utility values of the subjects most similar to the target subject to calculate the utility of the profiles that the target subject chooses. This approach assumes that subjects who deliberate in a similar alternative set may have similar preferences for each attribute level in decision making. The result shows the similarity between comparable alternatives the consumers consider buying is a significant factor to predict the consumer choice. Also the interaction effect has a positive influence on the predictive accuracy. This implies the consumers who looked into the same alternatives can probably pick up the same product at the end. The suggested alternative requires fewer predictors than conjoint analysis for predicting customer choices.

Purpose: This study is exploratory research to check the survey instrument KDSQ-C used to measure cognition for agreement between the elderly and their caregivers. Methods: Elderly persons from 170 families, who are aged over 65, have never been diagnosed with dementia, and who have caregivers in S City and K City were randomly selected by their nurses. A survey was conducted in the time from September to November, 2009 through personal interviews using a questionnaire. Results: In terms of consistency among items, there was high consistency (0.813) in the responses regarding complex task competence for the statement 'it is hard to reach a destination alone with public transportation'. There was relatively low consistency (0.63) in the responses regard memory for the statement 'they forget an appointment'. When the subject elderly and caregiver live together, as when their children or spouses responded, consistency was greater than when the caregiver lived in a different home. Conclusion: KDSQ-C showed high agreement in measurement between the subject elderly and their caregivers, demonstrating that it can be used as a measurement scale for cognition which can be directly applied to the subject elderly.
