This research aimed (1) to study and analyze the ability of current information retrieval (IR) systems based on views of information behavior (IB), and (2) to propose a conceptual framework for an IB model based on the collaboration between the system and user, with the intent of developing an IR system that can apply intelligent techniques to enhance system efficiency. The methods in this study consisted of (1) document analysis which included studying the characteristics and efficiencies of the current IR systems and studying the IB models in the digital environment, and (2) implementation of the Delphi technique through an indepth interview method with experts. The research results were presented in three main parts. First, the IB model was categorized into eight stages, different from traditional IB, in the digital environment, which can correspond to all behaviors and be applied to with an IR system. Second, insufficient functions and log file storage hinder the system from effectively understanding and accommodating user behavior in the digital environment. Last, the proposed conceptual framework illustrated that there are stages that can add intelligent techniques to the IR system based on the collaboration perspective between the user and system to boost the users' cognitive ability and make the IR system more user-friendly. Importantly, the conceptual framework for the IB model based on the collaboration perspective between the user and system for IR assisted the ability of information systems to learn, recognize, and comprehend human IB according to individual characteristics, leading to enhancement of interaction between the system and users.

본 논문은 주얼리 디자인 전공자에게 요구되는 기본소양인 기초조형의 공간지각 능력과 주얼리 디자인에 있어 가장 중요한 투시도법을 함께 활용하여 조형능력을 창의적으로 발휘 할 수 있는 수업 모형에 대해 연구한 논문이다. 이를 위해 연구자는 학생들에게 공간감을 나타낼 수 있는 방법에 대해 이론적으로 설명하고 기본도형과 입체도형, 투시도법에 대한 실기 수업을 진행한 후 창의적 활동을 위한 주제를 제시하고 결과물을 얻었다. 기존의 기초조형 수업에서 단순히 실기위주의 수업만 진행했다면 본 연구를 통해 학생들에게 안에서 창의력을 발휘하기 위한 분석과 기초투시도법, 공간감을 함께 융합적으로 활용할 수 있는 수업모형을 제시함으로 집중교육효과와 명확한 평가기준을 통해 학생과 교수 모두가 공감할 수 있는 평가방법을 알 수 있는 계기가 되었다. 본 논문을 계기로 더 다양한 재료와 융합적 수업모형에 대한 연구가 계속되기를 바란다.

This research examines performance evaluatees' opinions regarding the institutional performance evaluation systems of Government S&T Research Institutes (GRI). Research methodology is as follows: first, four perspectives of Kaplan & Norton (1992) Balanced Scorecard Model are revised into six perspectives suitable to GRI's characteristics. Second, experts classify current performance evaluation measures into the six perspectives. This enables different evaluation systems of three GRI evaluation groups to be compared under the same evaluation measures. Third, GRI's evaluatees are asked to allocate ideal weights on the performance measures. The evaluatees' weights are compared with the weights of current performance measures, and the characteristics of evaluatees' opinions about current performance evaluation systems are analyzed. Results are as follows; first, six perspectives for Korean GRIs are financial, long-term outcome, short-term outcome, strategic direction, project management, human resources perspectives. second, GRI evaluation systems put the most weights on the long- and short-term outcome perspectives and the least weights on the financial perspective. This result complies with theoretical model: in performance evaluation of GRIs, the customer perspective is the most important one while the financial perspective is the least important one. Third, evaluatees think that the long-term outcome perspective of the Basic-technology GRI group and the short-term outcome perspective of the Applied-technology GRI Group needs more weight. Fourth, it is found that the current systems have more weights on the project management and strategic direction perspectives than evaluatees think. The possible explanation of this result would be that since the measures of these perspectives are relatively easier to set up than those of other perspectives, the current systems contains larger number of measures and, accordingly more weights.

이 연구는 학생들의 생태 태도에 관한 두 가지 가설적 모델을 통계적으로 검증하였다. 첫 번째 연구 모델은 생물의 심미적인 관점이 부정적 관점으로 이어지는 경로에서 인식과 친숙함의 매개 효과이다. 두 번째 연구 모델은 인간적 관점에서 지배적 관점으로 이어지는 두 가지 차별적인 경로이다. 이 연구를 위하여 고등학교 1학년 학생 104명이 참여하였다. 상관관계, 편상관관계, 경로분석을 활용하여 모델의 적합도를 확인하였다. 연구 결과는 생물에 대한 인지와 친숙함이 심미적인 관점과 부정적 관점을 조절하고 있음을 보여주고 있다. 심미적인 관점에서 발생하는 학생들의 선입견이 학습으로 조절될 수 있음을 보여주고 있다. 두 번째, 인간적 관점과 지배적 관점 경로에서 생태-자연적 관점 경로와 과학-이용적 관점 경로는 독립적이다. 과학-이용적 관점은 지배적 관점에 정적인 영향력이 있다. 학생들의 자연에 대한 지배적 관점을 줄이기 위해서는 생태-자연적 관점을 이해할 필요가 있을 것이다.

The purpose of this study was to interpret modeling-based elementary science lessons from a perspective of distributed cognition. Data sources included three consecutive elementary science lessons dealing with particle models of gases and students' worksheet generated from modeling activities during the lessons. The data were analyzed in ways that could reveal the affordances and constraints of students' mental models and an external model in the science textbook, as well as the evolution of the models. The results showed that the students' mental models and the external model provided both affordances for and constraints to scientific problem solving and that the models evolved in the process of overcoming the constraints. Implications for science lessons and science education research were suggested.

In this study, software products developed in the course of testing, software managers in the process of testing software test and test tools for effective learning effects perspective has been studied using the NHPP software. The finite failure nonhomogeneous Poisson process models presented and the life distribution applied exponential and log shaped type hazard function. Software error detection techniques known in advance, but influencing factors for considering the errors found automatically and learning factors, by prior experience, to find precisely the error factor setting up the testing manager are presented comparing the problem. As a result, the learning factor is greater than autonomous errors-detected factor that is generally efficient model could be confirmed. This paper, a failure data analysis of applying using time between failures and parameter estimation using maximum likelihood estimation method, after the efficiency of the data through trend analysis model selection were efficient using the mean square error and coefficient of determination.

This study presents method for self-calibration of the SEM(Scanning Electron Microscope) stereo image using the standard microprobe with same grid pattern and using parallel and central perspective projection equation. Result showed that parallel projection method is more suitable for standard microprobe. The maximum error of 3D coordinates acquired by this method did not exceed 5 $\mu\textrm{m}$, and DSM(Digital Surface Model) for three dimensional measurement of the rock sample was generated by the digital photogrammetry. This result can be used for quantification of micro scale change of shape and analysis of the micro morphology of rock due to weathering.

The intention of this study was: 1) to standardize the Korean version of the Dogmatism Scale, 2) to examine whether environmental structure affects value systems such as attitudes toward work, time perspective and the personality dimension of dogmatism in adolescent vocational and non-vocational trainees, 3) to examine relationships between those value systems and group differences in personality characteristics of vocational and non-vocational trainees, 4) to observe whether there are differences between high-dogmatism and low-dogmatism subjects with regard to attitudes toward work and future time perspective. The subjects for the study included 841 adolescent vocational (226) and nonvocational (615) from vocational training centers, schools and universities in Seoul. The instruments used in this study were 1) a questionnaire for attitudes toward work, 2) the Future Time Perspective (FTP) developed by Christiansen and 3) the Dogmatism Scale. The results of the present study indicated that behavior settings or environmental variables such as organization type affect the formation of attitudes and of dogmatism in adolescents. The results also showed that dogmatism relates to future time perspectives. This differs from Rokeach's theoretical statements. Dogmatism in this study was related to time perspective, the relationships were optimistic in emotional areas, long-term in direction and concrete in structure. The inconsistency between the results of the present study and Rokeach's suggests further study. A "Psycho-Environmental Model" for the formation of value systems based on the results of this and earlier research of the author were discussed.
