자가 적응 시스템은 사람의 직접적인 개입 없이 자율 제어를 통한 자가 최적화 (self-optimization), 자가 치유 (self-healing) 등의 능력이 요구되고, 이러한 시스템은 시스템이 조달된 환경과 시스템 내부 상황을 고려한 적절한 적응 정책과 목표 평가를 통해 시스템의 신뢰성을 보장할 수 있어야 한다. 목표 기반의 자가 제어 시스템은 목표 만족도에 따라 시스템을 자율 제어하기 때문에 목표 기반 자가 적응 시스템에서의 목표 만족도(goal satisfaction) 평가는 매우 중요하지만 기존의 연구들의 목표 만족도 평가 방법에서는 환경 변화가 반영되지 않는다는 한계가 있다. 본 논문에서는 목표 모델에서의 상위 목표에 대한 하위 목표들의 기여도에 따라 가중치를 부여하고 시스템의 외부 환경 변화에 따라 가중치를 동적으로 변경하는 방법을 제안한다. 이를 통해 기존의 목표 평가 방법보다 사용자의 요구가 잘 반영되고 신뢰성 높은 평가가 가능하다.

본 논문은 현재 국방 체계의 상호운용성 수준을 평가하는 방법으로 사용하는 LISI 모델에 대해 개선되어야 할 내용을 제시한다. 우리 군은 국방 체계에 대해 상호운용성 수준 측정을 위해 LISI를 기반으로 한 자동화 도구를 활용하는 등 상호운용성 확보를 위해 많은 노력을 기울이고 있다. 그러나 소요제기/개념단계, 설계 단계에서 적용되는 LISI 모델에는 미흡한 점이 있다. 이를 극복하기 위해 본 논문에서는 아키텍처 구축 시 LISI를 적용하는 방법에 대해 제안한다. 상호운용성이 확보 가능한 아키텍처를 구축하기 위해 서는 LISI를 기반으로 아키텍처 대안들을 평가함으로써 향후 개발에 적용될 아키텍처가 상호운용성 요구를 달성하고 있음을 검증해야 한다. 더불어 본 논문은 LISI 모델 기반 상호운용성 평가를 위해 주요하게 고려되는 능력모델에 대한 절차(P), 응용(A), 기반구조(I), 데이터(D) 내용을 참조모델을 통해 최신화하는 방안에 대해 제안한다.

The objective of this paper is an implementation of analysing and predicting functions to promote self-directed learning for student's performance assessment system in programming subjects. By adapting Rubric model, the proposed functions inform a student of the assessment criteria and level to be carried out with respects to two-way specifications such as rational ability, problem solving ability and creativity. The proposed system also provides a graphical results of each ability instead of assessment result, for better understanding and analyzing himself/herself based on to the performance assessment and the result. Moreover, the proposed system contains a method to predict future achievement result with moving average technique. Therefore, an academic achievement can be precisely determined by himself/herself to estimate self-directed learning. The teacher can provide different level of educational resources such as supplement learning, problem explains and private instructor etc., in order to maximize efficiency of education.

It is organized to evaluate the effect of nursing students' learning attitude, learning motivation, problem solving ability, and class participation, after applying team-based learning to basic nursing classes. The subjects were 103 people in the second year of the G region. The data collection was from September 1 to December 5, 2016 by using t-test, one-way ANOVA, paired t-test and Pearson's correlation coefficient. Result is that the ability to solve problems increased, showing a statistically significant difference. Learning attitude and motivation of learning increased and the degree of participation didn't change, but there were no statistically significant differences. The learning attitude shows positive correlation with learning motivation, problem-solving skills and participation. After team based-learning, learning attitude showed a positive correlation with learning motivation, problem solving ability and class participation. Learning motivation shows positive correlation with class participation and so does problem solving ability with participation. Based on the results of this study, in order to improve the practical ability, it is necessary to activate the self-directed active learning method such as team base for nursing major study.

In the advanced information age, learning is an activity in which learners access information resources through computers and Internet to acquire and evaluate information on their own. The emergence of an online learning platform based on the fourth industrial revolution technology is developing into an environment in which elementary and secondary learners learn and study based on constructivism learning theory. In the online learning environment, the researches on the information retrieval ability of the elementary and secondary learners and the self-directed learning ability were found to be highly related. However, it is necessary to analyze the relation between information retrieval ability and self-directed learning ability through a cross-sectional study that is limited to specific curriculum and contents and expands the longitudinal research. In this study, the panel data of the Seoul Education Longitudinal Study collected over 8 years are used to find the difference in self-directed learning ability according to the longitudinal pattern of information retrieval ability and frequency.

Information literacy which is related various forms of literacy can be defined as a vital competency of individuals in digital based knowledge information society. This basic survey research is aimed to assess information literacy level of the undergraduate students. For this study a proper model of information literacy is used which based 5 Performance processes and 12 performance abilities. The result of this survey is as follows: 1) Among the S performance process elements.'result evaluation' element showed high level competency than other elements. 2) There were high correlations within performance Process elements and performance ability elements. 3) Those items such as academic grade, first experience of information retrieval, and experience of information literacy instruction affect the difference in the level of information literacy.

In real software development fields, software is unified by several modules that are developed before the software testing period. For the evaluation of software task processing performance, this paper considers the software imperfect debugging model that is proposed by Lee and Park (2003) and presents the measures of a unified software, such as the completion probability of a task which is completed in a time interval and the expected number of the completed tasks. In addition, we suggest a software release policy that satisfies the required level of the expected perfect debugging, completion probability, and availability.

The purpose of this study is to investigate the effect of flipped learning-based health assessment education on academic achievement of nursing students. The subjects of the study included nursing students attending second year at university. For 10 weeks, the experimental group was exposed to flipped learning-based classes, and the control group was provided with traditional lectures and team learning-based classes. In the intermediate evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant, and in the final evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant. The integrated knowledge score, evaluated three times after the end of the training, was higher in the experimental group than in the control group. These results suggest that flipped learning is an effective teaching and learning method for improving knowledge and performance of nursing students. Therefore, the application of flipped learning in various nursing education areas should be studied.

The purposes of this research are to verify: first, if the technology appraisal model reflects the company's management performance and the rates of bankruptcy and overdue; second, if the existing classification system of technology levels is suitable; and third, which is the most important appraisal factor that defines the classification system of technology levels. As a result of the analysis, financial performance (stability) and non-financial performance (technology environment) proved to be significant variables in explaining technology ratings. According to the verification of the suitability of classification system, it appeared that there is a significant difference in all appraisal items of all groups. The result of neural networks model verification indicates that the most important variable was the R&D capacity, the second variables which determine the suitability of technology financing were indicators related to the company management. The second variables which determine a company's technological excellence were a company's technological base. To summarize, the technology appraisal model not only reflects both managerial performance and risks of a company, but also anticipates the future by converging the management competence and technological competitiveness into R&D capacity. This implies that if the 'forward-looking' technology appraisal model is integrated into the existing, credit rating model, the appraisal model may have positive impact on improving anticipation and stability.
