Purpose: This study investigated the effectiveness of simulation training with a hybrid model of student nurses' performance ability and reported self confidence. Methods: A nonequivalent control group with pre-posttest was designed. Data collection was done during the first semester in 2012 at a college of nursing in Seoul. Nursing performance ability and reported self confidence related to taking care of patients with urinary problems were evaluated. The treatment group (n=96) received simulation training of a catheterization procedure with a hybrid model involving standardized patients and a mannequin. Nursing students in the comparison group (n=84) did not receive the simulation training but would receive it prior to their next clinical practicum's. Results: The treatment group showed a significantly higher performance ability and reported self confidence than that of the comparison group. The perceived helpfulness and contentment of the simulation training in experimental group was high. Conclusion: The findings of this study demonstrated that simulation with a hybrid model was effective in teaching skills prior to the clinical experience which suggests that skill development is not dependent on the actual clinical situation. Nurse educators should consider simulation training as a tool beyond that of clinical practicum.

We carried out a follow-up study on the students who participated in International Astronomy Olympiad(IAO). We surveyed home and school environment, personal characteristics with regard to four high school student and five college students who participated in IAO from 2002 to 2005. In the home environment variable of science elite students who took part in the IAO, we found out significant corelation between science elites and their parent's educational career. In their personal characteristics, we found out considerably their motivation capacity, intelligent curiosity, flexible and creative thinking ability. This study illuminated that the experience of IAO participation offered the opportunity for the students to gain mare self-esteem and positive confidence on scientific study. The IAO experience is construed to effect greatly the students' future. Through the IAO experience, the participating students are expected to major in astronomy and become excellent astronomers in the future. We expect that the interest of student will increase greatly in the area of astronomy and it will contribute to the substantial development of Korean astronomy. In this respect, with the constant support to the IAO participants, the effort to cultivate outstanding astronomers and follow-up study on those participants of the IAO should be continued.

Digital textbook project is one of government-driven project to improve education due to integrating technology. Digital textbook need to be universally designed to fit for each student. Recently, universal design for learning( UDL) gains great attention as one of promising approaches for the development of the digital textbook through giving various options and flexibility to all students. UDL has three main principles, first provide multiple means of representation, second provide multiple means of action and expression, third provide multiple means of engagement. The purpose of the study is to analyze fourth grade science textbook according to three UDL guidelines and suggest implications to improve an existing science textbook. The results indicated that fourth grade science digital textbook has been partly applied UDL guidelines like implementing multimedia and multi- mode contents, learning and communication tools, and motivation strategies. But options which students can choose according to their needs and styles are insufficient and tools for expression and communication need to enhance for helping each student to overcome his/her obstacles for learning and need to be more and elaborate to support learner-centered science digital textbook.

The purpose of this study was to develop criteria for evaluating final reports of free inquiry activity and to apply developed evaluation criteria to free inquiry activity reports. 323 inquiry reports submitted to internal contests in the elementary schools as well as 189 award-winning ones from the inquiry competition for students in Seoul were collected. Nine categories and 18 sub-categories of evaluation criteria were derived by collecting reports analysis, literature reviews and interviews with 15 elementary school teachers. Criteria for each sub-category were organized into three steps and 12 elementary school teachers assigned scores for each sub-category, which were averaged. 132 including both award-winning and general reports were evaluated based on the developed evaluation criteria. The content validity and the reliability across scorers were significant. Furthermore, award-winning and general reports were significantly distinguished by the developed criteria in terms of all sub-category scores. The developed evaluation criteria will be an effective tool to asses student's free inquiry activity.

Objectives: Students' life changes substantially as grade increases. It implies that risk factors that trigger students' smoking may not be consistent across grades. Most previous studies on student smoking have considered grade simply a control variable. This study examines which and to what extent risk factors are differently associated with smoking initiation according to grade level among high school students in Korea. Methods: Data from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted by the Korea Centers for Disease Control and Prevention (KCDC) in 2007 and 2008 were analyzed in this study. Results: Among boys, school location, school type and pocket money etc. significantly influence smoking initiation in the first grade than in any other grades, but the strength of the association decreased as grade increases except academic performance. Among girls, most independent variables were associated with smoking initiation in the second grade except school location, pocket money per week and academic performance. Conclusions: Our results suggested that the variables related smoking initiation in Korean high school students were notably different by grade and gender. These findings can serve as the basis of policy recommendations with regard to school efforts to prevent student smoking.

WBI(Web Based Instruction) has been confined to some course due to a burden of development of instruction materials. In this paper, we implemented a personalized instruction and learning system for Word Processor based on Internet by using WBI. Compared to the traditional instruction and learning method for Word Processor Education, the proposed method induce students to take an interest in the learning and make it possible to do student oriented instruction and learning due to the selection of specific contents according to student's ability and his/her learning step. And this system can evaluate the learning rate on the spot by using personalized homework and maximize learning effect by using feedback.

Recently our educational methodologies have been changed to an open, student-centered structure. Mathematics is now learned through experiential interaction and less emphasis is placed on abstract theories. For example, the axioms of the geometry in the middle school curriculum have been expressed by using symbolic letters. Students find these abstractions very difficult and it hinders their ability to grasp the significance of geometrical concepts. In an effort to simplify these abstract concepts and enhance the students interest and ability to learn, the GSP (Geometry Sketchpad) is proving to be a useful and effective tool. First, Second and third grade students have found the GSP to be extremely useful. While the pad has no sound function it still enables the students to freely change diagrams without disrupting the integrity of the program. There is also a running order of instructions at the bottom of the screen to facilitate the step by step understanding of mathematical procedures. This function makes the program ideal for use by teachers, students and even beginners. Anyone experiencing difficulty can get immediate assistance from the guidebook which is located at the back of each program. Allowing individuals to manipulate and actually see the changing deductions and axiom proofs on the computer screen provides them with immediate feedback and reinforcement. It also enhances their overall interest in learning geometry. The use of the GSP is proving to be an innovative and effective tool in facilitating the transition of mathematics into an open, student-centered educational forum.

Most accident reconstruction or analysis depend on the coefficient of friction to estimate the vehicle speeds. Skid mark and coefficient of friction are usually utilized to calculate the velocity and behavior of vehicles. For a critical case such as traffic accident reconstruction, however, the initial velocity of the car should be calculated precisely. In this paper, emergency brake tests on ABS and Non-ABS brake system are conducted on the dry pavement asphalt road on speed 40, 60, 80 and 100 km/h respectively. The SWIFT sensor was established in the front wheel and rear wheel at driver side to measure the forces, moments and speeds of revolution of the tires. These tests results can be available to brake tests and accident reconstruction.

Manufacturing fabrics from dissolving cellulosic pulp is increasing in these days. For making high quality of cellulose-based fabrics, control of cellulose DP (degree of polymerization), its alpha cellulose content, its brightness, and its crystallinity are important. To process the cellulosic raw material, refining of cellulosic fibers is essential, and it is important to know if refining affects those important cellulose properties. The effects of PFI mill and Valley beater refining on the alpha-cellulose content, cellulose DP, crystallinity, and paper mechanical properties of wood and two different cotton fibers were studied. The results showed that PFI mill refining rarely affected those properties. Fibers refined by a Valley beater displayed a small reduction in fiber length in comparison with those refined by a PFI mill. However, the Valley beater refining method produced almost no changes in cellulose properties, either. The refining process seemed to have very little effect on the cellulose DP, crystallinity index, or alpha-cellulose content until the freeness decreased to around 300 mL CSF for wood and 100 mL CSF for cotton fibers, respectively. There were also no differences in tensile strength development in two refining methods.
