지식 기반 사회에서 지식과 정보를 활용하여 문제를 해결하는 능력은 매우 중요하다. 또한 기존의 지식으로 해결할 수 없는 다양한 문제 상황이 증대되고 있다. 따라서 본 연구에서는 정보의 체계적 수집 및 활용을 통한 창의적 아이디어 생성 및 이를 활용한 문제해결력 향상을 위한 정보 교육 프로그램을 개발하였다. 해당 프로그램은 발산적 사고와 수렴적 사고를 모두 다룰 수 있도록 조직하였으며, 문제 해결의 전체적인 경험을 제공하고 학습자 내부 지식 뿐 아니라 새로운 정보를 수집, 활용하여 문제를 해결하는 능력 향상에 초점을 두고 구성하였다. 또한 정보 활용 난이도에 따라 분리된 프로그램을 개발하였다.

This paper is resulted from the research to activate Self-control Safety Management system that adopted to improve an assessment system for Hazard Prevention Plan. And members of company, university and research institute have jointly participated in the research. First, it is investigated that introduced background and processing method with existing practical data & materials references in order to understand what domestic Self-control Safety Management system will be available for. And general construction company at site have their ability to assess Hazard Prevention Plan by mailing questionnaire to on thousand site, visits, and interviews. Also, It is investigated how much they have the assessment ability. It is selected to do a questionnaire survey for the status of self-regulatory safety assessment ability of the designated self-regulatory companies in order to produce and enhance the self-regulatory assessment ability and the necessity of Self-control Safety Management system. Finally, it is selected to do a questionnaire survey for fixing and the enhance Self-control Safety Management system of general construction contractors.

Dyeing properties of protein fiber with bamboo colorants were studied by investigating the effect of dyeing conditions such as dye concentration, dyeing temperatures, times on dye uptakes, effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use. In addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were estimated. The dye uptake increased as the dyeing concentration increased. Bamboo colorants showed relatively good affinity to protein fiber and produced a yellow color. Dye uptake increased as the dyeing time and temperature increased. Post-mordanting was more effective than pre-mordanting. Mordants, Fe and N.Fe, were effective for increasing dye uptake. The color of fabric mordanted with Cu and N.Cu changed to GY. Colorfastness of dyed fabrics showed a relatively good rating, and mordanting had no significant effect on colorfastness. Dyed silk fabric showed very good antimicrobial abilities of 99.9%. Also, ultraviolet-cut ability and deodorant ability were improved in silk fabric dyed with bamboo extracts.

다층 퍼셉트론(Multi-Layer Perceptron, MLP) 구조는 그의 비선형 적합능력으로 인하여 매우 다양한 실제 문제에 적용되고 있다. 그러나 일반화된 MLP 구조의 적합능력은 은닉노드의 개수. 초기 가중 값 그리고 학습 회수 또는 학습 오차와 같은 구조인자(factor)들에 크게 영향을 받는다. 만약 이들 구조인자가 부적절하게 선택되면 일반화된 MLP 구조의 적합능력이 매우 왜곡될 수 있다. 따라서 MLP구조에 영향을 주는 인자들의 결합 영향을 살펴보는 것은 중요한 문제이다. 이 논문에서는 제어상자(controller box)를 통한 학습결과와 더불어 MLP구조를 일반화할 때 영향을 줄 수 있는 신경망의 일반적인 구조인자 들을 실증적으로 살펴보고 이들의 상대효과를 비교한다.

Purpose As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitments, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with MIS(Management Information Systems) field is 'information ability', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' information ability on their career preparation behavior. Design/methodology/approach In this study, we set up a process model to comprehend the effect of college students' information ability on career preparation behavior based on social cognitive career theory. For research model testing, 561 questionnaires were used for empirical analysis through structural equations modeling. Findings Empirical analysis showed that information ability positively influenced college students' career preparation behaviors for employment. In addition, this study presented a process model explaining the effect of information capability on career preparation behavior. In order to strengthen the information ability of college students, not only university-level efforts, but also MIS discipline efforts should be accompanied. Other academic and practical implications are discussed.

Purpose: The purpose of this study is to investigate the improvement measures of dental technician practical examinations. Methods: A survey was performed on 37 professors through a questionnaire. The results were analyzed by SPSS 12.0. The collected data was analyzed by frequency and the chi-square test. Results: The education compared to the satisfaction of practice examinations only differs in the method of enforcement(p<.05). The evaluations on the ability to perform the job with practical subjects were inadequate (37.8%). Questions with the most necessary work tools through the articulator was highest at 48.7%, Electric wax carver was 32.4%, and heating clear was 3.5%. Conclusion: There must be an improvement to increase the cooperation within the clinical department, while considering the practical exam environment.

The ability to efficiently and robustly recover accurate 3D terrain models from sets of stereoscopic images is important to many civilian and military applications. To develop an effective and practical terrain modeling system, we propose a new multi-image stereo method which detect unreliable elevations in DEM(Digital Elevation Map), and fuse several DEMs from multiple sources into an accurate and reliable results. This paper focuses on two key factors for generating robust 3D terrain models: the ability to detect unreliable elevation estimates and the ability to fuse the reliable elevations into a single optimal terrain model. We apply the self-consistency methodology to reconstruct accurate DEM from multi-image and show the method is more effective than the conventional stereo image 3D reconstruction method. Using photo-realistic simulator, four synthetic image are generated from ground truth DEM and orthoimage to evaluate the accuracy of the proposed method quantitatively.

The influence on children's analogical problem solving of structural highlighting during encoding and retrieval of sources was studied with 379 9-year-old participants. Performance on the first 2 of 4 tests determined the analogical level of each child. For the remaining 2 tests, the child was assigned to 1 of 12 different structural highlighting conditions, including 4 encoding conditions (reading, line, self-line, and self-explain) and 3 retrieval conditions (reminding, cued, and thematic comparison). Results showed that retrieval conditions, not encoding conditions, improved the analogical ability of the child. Children initially low in analogical ability improved in cued retrieval conditions; children initially high in analogical ability improved both in thematically compared and in cued retrieval conditions. Practical implications of the results were discussed.

For the purpose of adapting positively to the information society, it is very important to develop the capabilities of the retrieve, gather, process and application for informations by making efficient use of computers. So, with a view to understanding the importance of computer and adjusting actively to the information society, the systematic policy to cultivate the ability of making the most of computers is strongly demended. Therefore this study is to make a curriculum and guide for improving the capability of applying computers systematically, through analyzing a curriculum of computer in Elementary, Middle and High Schools, and to develop a model of grading system to cultivate the ability of applying computers, which grades capabilities of its practical use.
