In school safety education, it was difficult to apply how to link the safety education according to grades year, and student's interest was reduced due to the repetition of existing safety education contents and the absence of new teaching methods and tools. In this study, as a new type of safety education, a performance forms fire safety education program was developed. This program aims to increase students' interest and satisfaction in safety education, and to this end, it was connect with korean elementary science curriculum and combined various engineering teaching materials or tools and methods. Developed program was applied to 2,231 students, 25 schools in 10 regions of Gyeonggi-do and surveyed 476 fifth and sixth grade students program satisfaction and 3 factors of interest in fire safety education who could respond to the survey. As a result of applying the program, more than 90% of students responded more than 'satisfied' in all areas. and statistical test(independent t-test and non-parametric test) indicates over-all satisfaction and interest factors in the program are high regardless of gender and grade, so the effectiveness can be guessed indirectly and there is a universal applicability also. Moreover, examining the influence of student interest level in the satisfaction of the fire safety program, it was found that in order to increase the satisfaction of fire safety education, students should have more fun with the content and feel interest in the teacher's teaching method or explanation.

Most medical colleges in Korea have been shifting from traditional education to outcome-based education, which is the general trend in medical education. The purpose of this study was to make some suggestions in light of the reality and challenges of student assessment in medical education from the perspective of outcome- based education. First, those who are responsible for student assessment should be diversified to include faculty, residents, students, and evaluation committee members. They need separate roles in educational evaluation, so evaluation competencies are required for them. Second, various methods for evaluation and score interpretation can be used for effective evaluation. We can adopt diagnostic, formative, and summative evaluation functionally, and the norm-referenced, criterion-referenced, growth-referenced, and ability-referenced evaluation based on criteria for score interpretation. Finally, various evaluation domains and test forms can be administered together in the common lectures in the medical school. We can test not only knowledge but also skills and attitudes, with diverse test forms such as supply and performance types.

현재 과학과 수행평가는 교사평가가 주를 이루고 있기 때문에 평가 결과의 피드백이 신속하게 이루어지지 못하고, 시 공간적 제약으로 인하여 동료평가가 거의 이루어지지 않는다. 또한 과학과 수행평가에서 주로 시행되는 보고서 수행평가의 경우 체계적인 형식 없이 실험관찰에 기록된 내용으로 평가되는 경우가 많다. 이러한 수행평가 방법은 수행 기준의 공유를 통한 성취의욕 향상, 평가결과의 즉각적인 피드백을 통한 자기조정이라는 수행평가의 기대에 부응하지 못할 수밖에 없다. 따라서 본 연구에서는 웹을 기반으로 동료학습자 간의 자료공유와 토의를 통해서 실험 및 조사 보고서를 완성하고 이를 동료평가, 교사평가에 활용하며 그 결과를 통해 학습자의 요구 수준을 파악하고 학습자에게 적절한 피드백을 제공하는 수행평가 시스템을 개발하였다.

Based on the value of the Lagrange multiplier and the degree of constraint activeness, a new update rule is proposed for penalty parameters of the ALM method. The theoretical exposition of this suggested update rule is presented by using the algorithmic interpretation and the geometric interpretation of the augmented Lagrangian. This interpretation shows that the penalty parameters can effect the performance of the ALM method. Also, it offers a lower limit on the penalty parameters that makes the augmented Lagrangian to be bounded. This lower limit forms the backbone of the proposed update rule. To investigate the numerical performance of the update rule, it is embedded in our ALM based dynamic response optimizer, and the optimizer is applied to solve six typical dynamic response optimization problems. Our optimization results are compared with those obtained by employing three conventional update rules used in the literature, which shows that the suggested update rule is more efficient and more stable than the conventional ones.

Five solution styrene butadiene rubber/neodymium butadiene rubber (SSBR/NdBR) composites were manufactured using different ratios of SSBR and NdBR. In this study, the composites were reinforced with NdBR and silica to confirm the physical properties of SSBR used for treads of automobile tires and the dispersibility with silica. The morphologies of the rubber composites were observed using field-emission scanning electron microscopy (FE-SEM). The crosslinking behaviors of the composites were tested using a rubber process analyzer (RPA), and the abrasion resistances were tested using a National Bureau of Standards (NBS) abrasion tester. The hardness values, tensile strengths, and cold resistances of the composites were also tested according to ASTM standards. Increased NdBR content yielded composites with excellent crosslinking properties, abrasion resistances, hardnesses, tensile strengths, and cold resistances. The crosslinking point increased due to the double bond in NdBR, thereby increasing the degree of crosslinking in the composites. The NdBR-reinforced composites exhibited excellent abrasion resistances, which is explained as follows. In SSBR, a breakage is permanent because a resonance structure between styrene and SSBR forms when the molecular backbone is broken during the abrasion process. However, NdBR forms an additional crosslink due to the breakdown of the molecular backbone and high reactivity of the radicals produced. In addition, the low glass transition temperature (Tg) of NdBR provided the rubber composites with excellent cold resistances.

A corporate university (CU) is an educational institution established by an organization whose primary purpose is not education. Traditionally, a CU is considered a training facility to improve organizational performance. However, the proliferation of the CU has engendered its diverse purposes, roles, and forms. This study attempts to identify three types of the existing CUs: (a) a CU to improve organizational performance; (b) a CU to satisfy employees' learning needs; and (c) a CU to develop a competent national workforce. Also, this study suggests a holistic CU model including the three CU types. In order to transform a CU to a multifunctional CU embracing all three types of CU, organizations should (a) provide communication and collaboration channels, (b) present clear organizational goals, (c) establish organizational policies/systems to encourage learning in CUs, and (d) devise an effective approach to evaluate the impact of CUs. Organization' s critical roles in the development of CUs can assist CUs in becoming the core of knowledge management.

Background Comprehensive aesthetic surgery training continues to be a challenge for residency programs. Our residency program developed a rhinoplasty-based objective structured clinical examination (OSCE) based upon validated methods as part of the residency education curriculum. We report our experience with the rhinoplasty-based OSCE and offer guidance to its incorporation within residency programs. Methods The encounter involved resident evaluation and operative planning for a standardized patient desiring a rhinoplasty procedure. Validated OSCE methods currently used at our medical school were implemented. Residents were evaluated on appropriate history taking, physical examination, and explanation to the patient of treatment options. Examination results were evaluated using analysis of variance (statistical significance P<0.05). Results Twelve residents completed the rhinoplasty OSCE. Medical knowledge assessment showed increasing performance with clinical year, 50% versus 84% for postgraduate year 3 and 6, respectively (P<0.005). Systems-based practice scores showed that all residents incorrectly submitted forms for billing and operative scheduling. All residents confirmed that the OSCE realistically represents an actual patient encounter. All faculty confirmed the utility of evaluating resident performance during the OSCE as a useful assessment tool for determining the Next Accreditation System Milestone level. Conclusions Aesthetic surgery training for residents will require innovative methods for education. Our examination showed a program-educational weakness in billing/coding, an area that will be improved upon by topic-specific lectures. A thoroughly developed OSCE can provide a realistic educational opportunity to improve residents' performance on the nonoperative aspects of rhinoplasty and should be considered as an adjunct to resident education.

An effective educational program warrants the inclusion of an innovative construction which enhances the higher education efficacy in such a way that accelerates the achievement of desired results and reduces the risk of failures. Educational Decision Support System (EDSS) has currently been a hot topic in educational systems, facilitating the pupil result monitoring and evaluation to be performed during their development. Insufficient information systems encounter trouble and hurdles in making the sufficient advantage from EDSS owing to the deficit of accuracy, incorrect analysis study of the characteristic, and inadequate database. DMTs (Data Mining Techniques) provide helpful tools in finding the models or forms of data and are extremely useful in the decision-making process. Several researchers have participated in the research involving distributed data mining with multi-agent technology. The rapid growth of network technology and IT use has led to the widespread use of distributed databases. This article explains the available data mining technology and the distributed data mining system framework. Distributed Data Mining approach is utilized for this work so that a classifier capable of predicting the success of students in the economic domain can be constructed. This research also discusses the Intelligent Knowledge Base Distributed Data Mining framework to assess the performance of the students through a mid-term exam and final-term exam employing Multi-agent system-based educational mining techniques. Using single and ensemble-based classifiers, this study intends to investigate the factors that influence student performance in higher education and construct a classification model that can predict academic achievement. We also discussed the importance of multi-agent systems and comparative machine learning approaches in EDSS development.
