Purpose: The purpose of this study was to investigate factors which influence freshmen nursing students' problem solving abilities. Method: The data were collected from 119 students by means of self-reported questionnaires measuring problem solving abilities, critical thinking disposition, and self-directed learning, on March 7th and 11th, 2010. Result: For problem solving ability categories, the level of problem discovery was the highest followed by solution plan, problem definition, solution evaluation and solution implementation. The influencing factors on problem solving abilities of nursing students were critical thinking disposition, self-directed learning and gender. Conclusion: Using the results of this study as a foundation, nursing education curriculum should be comprised of critical thinking skills and self-directed skills for the improvement of nursing students' problem solving abilities. It is also recommended that further studies be conducted in order to investigate comprehensive curriculum designs that allow for maximum accumulation of these proficiencies.

Background: If patients have a better understanding about their problem and treatment, compliance and satisfaction with treatment will increase. For this purpose, simple repeated explanations regarding a patients' problem and treatment are essential. Critical pathway (CP) has a very wide range in medicine with the exception of the plastic surgery field. The authors developed a CP for facial bone fractures and implemented it clinically. The aim of this study was to evaluate the effectiveness of the CP on the degree of recognition of the problem along with patient satisfaction with the treatment process. Methods: From May 2011 to October 2011, a total of 82 patients suffering from facial bone fractures were studied. The CP for facial bone fractures was developed by plastic surgeons, residents and nurses. Subsequently, the authors investigated the degree of recognition of the disease and patient satisfaction with the treatment through the use of a questionnaire. The authors compared the score of the questionnaires before and after implementation of the clinical pathway. Results: The degree of the recognition of the problem changed from 3.1 to 4.2 (p<0.001). Further, the degree of satisfaction with the treatment process changed from 3.6 to 4.3 (p<0.05). Overall, there was a two point increase in improvement. Conclusion: Implementation of the CP for facial bone fractures was effective in improving the degree of recognition and satisfaction. The authors expect that hereafter, the CP for facial bone fractures will be implemented actively in the plastic surgery field.

The successful use of digital textbooks (DTs) in schools requires the development of various teaching and learning methods that are appropriate for DTs. However, recent DT studies have focused mainly on the implementation of DT features and formats. The objective of this study was to investigate a problem-based learning instructional model appropriate to DTs and to present the experimental results using the problem-based DT to demonstrate its educational effectiveness. Two learning-achievements tests were conducted to analyze the learning experience and effectiveness of the problem-based DT after it had been used in a high school for a certain period. The experimental results indicated that the students who used the DT, especially lower-level students, exhibited improved problem-solving ability and demonstrated a better practical understanding of the subject than students who used printed textbooks.

Electromagnetic suspension (E.M.S) type levitation system is studied in the control system design viewpoint. Dynamic characteristics in theoretical analysis as well as hardware implementation is considered. Open loop unstable, non-linear and timevarying characteristics are reviewed in the theoretcal section, while levitation control system for multi-vehicle train as well as magnet drive system is reviewed in the practical section. This paper suggests not only some well-known problem appearing in levitation control system design but also a subtle problem and solution candidates. But there exist many unmentioned problems wating for a smart problem solver.

Motif databases are used in the function and structure prediction of proteins. The frequency of use about these databases increases continuously because of protein sequence data growth. Recently, many researches about motif resource integration are proceeding. However, existing motif databases were developed independently, thus these databases have a heterogeneous search result problem. Database intnegration for this problem resolution has a periodic update problem, a complex query process problem, a duplicate database entry handling problem and BML support problem. Therefore, in this paper, we suppose a database resource integration method for these problem resolution, describe periodically integrated database update method and XML transformation. finally, we estimate the implementation of our prototype and a case database.

In this paper, we deal an implementation of the software that produces sub-optimal solution of cutting-ironbar planning problem using dynamic programming. Generally, it is required to design an optimization algorithm to accept the practical requirements of cutting ironbar manufacturing. But, this problem is a multiple-sized 1-dimensional cutting stock problem and Linear Programming approaches to get the optimal solution is difficult to be applied due to the problem of explosive computation and memory limitation. In order to overcome this problem, we reform the problem for applying Dynamic Programming and propose a cutting-ironbar planning algorithm searching the sub-optimal solution in the space of fixed amount of combinated columns by using heuristics. Then, we design a graphic user interfaces and screen displays to be operated conveniently in the industry workplace and implement the software using open-source GUI library toolkit, GTK+.

This study examined the influences of science project activities based on multiple intelligences on problem solving behaviors of elementary school children. Specifically, the influences of the project activities on the problem solving skills and propensities of the children were investigated. Forty-four fifth graders were selected for the study. They performed the projects and made their products of it during five months on the units of "Weather" and "Our Body" Criteria for assessment of problem solving abilities were determined. The patterns reflected in products of the project activities were examined, then the observation of the subjects' problem solving behaviors and the interviews were performed based on the criteria. The results were analyzed through both of qualitative and quantitative approaches. In these analyses, the implementation of the science projects was found to contribute to the improvement in all sub-factors of problem solving, specially, skills associated with the propensities of problem identification and of the collection, analysis, and synthesis of data significantly increased
