Objectives: Many female college students today control their lifestyle not for the purpose to promote their health but to maintain slender figures. The purpose of this study was to explore and describe the lifestyle of female college students from their own perspectives. Methods: Data was collected through interviews of 25 female students and was analyzed by using Colaizzi's descriptive phenomenology(1978). The phenomenon of interest was described, followed by collecting participants' descriptions of the phenomenon and extracting concepts from significant statements. These concepts were then organized into thematic clusters, followed by exhaustive descriptions into which data was applied to extract the final categories. Results: The results were deduced into 226 re-statements, 38 constructed meanings, 23 themes, 11 theme clusters, and 5 categories. The five categories include 'Increased interest in physical health,' 'Selective dietary patterns influenced by lifestyle,' 'Lifestyle formed by social adaptation,' 'Health complications caused by self-body images,' 'Engages in healthy dietary behavior'. Conclusion: This study described the experiences of female college students' lifestyles after completing a course in health promotion. These findings have important implications on health education for college students which should be considered in developing health education programs in preparation for adult years of life.

In a Vehicle, Safety is the most important factor for drivers. It is well known that tire pressure lower than normal reduces the safety of the vehicle. In a consideration of active safety, tire pressure monitoring system is absolutely required. Tire pressure monitoring using in-tire pressure sensors with an RE data link have proven to be best approach to measuring tire pressure over the widest range of operating conditions. In this paper, we describe the parameters of TPMS, the characteristic of tire pressure and temperature compensation. These are the main factors to design the decision logic. We will show the guidelines for TPMS logic development considering environment variables and vehicle conditions.

A dedicated reverse engineering(RE) system for rapid manufacturing of human head in a 3D bust has been developed. The first step in the process is to capture the surface details of a human head and shoulder by three scanners based upon the digital moire fringe technique. Then the multiple scans captured from different angles are aligned and merged into a single polygonal mesh, and the aligned data set is refined by smoothing, subdividing or hole filling process. Finally, the refined data set is sent to a 4-axis computer numerically control(NC) machine to manufacture a replica. In this paper, we mainly describe on the algorithms and software for aligning multiple data sets. The method is based on the recently popular Iterative Closest Point(ICP) algorithm that aligns different polygonal meshes into one common coordinate system. The ICP algorithm finds the nearest positions on one scan to a collection of points on the other scan by minimizing the collective distance between different scans. We also integrate some heuristics into the ICP to enhance the aligning process. A typical example is presented to validate the system and further research work is also discussed.

Failure Mode, Effects, and Criticality Analysis (FMECA) is an extension of FMEA which includes a criticality analysis. The criticality analysis is used to chart the probability of failure modes against the severity of their consequences. The result highlights failure modes with relatively high probability and severity of consequences, allowing remedial effort to be directed where it will produce the greatest value. However, there are several limitations. Measuring severity of failure consequences is subjective and linguistic. Since The result of FMECA only gives qualitative and quantitative informations, it should be re-analysed to prioritize critical units. Fuzzy set theory has been introduced by Lotfi A. Zadeh (1965). It has extended the classical set theory dramatically. Based on fuzzy set theory, fuzzy logic has been developed employing human reasoning process. IF-THEN fuzzy rule based assessment approach can model the expert's decision logic appropriately. Fault tree analysis (FTA) is one of most common fault modeling techniques. It is widely used in many fields practically. In this paper, a simple fault tree analysis is proposed to measure the severity of components. Fuzzy rule based assessment method interprets linguistic variables for determination of critical unit priorities. An rail-way transforming system is analysed to describe the proposed method.

Purpose: To describe a technique of the modified Neviaser method and to evaluate the clinical outcome of the technique in the treatment of the complete acromioclavicular joint dislocation, Materials and Method: We evaluated 20 patients who were treated by a modified Neviaser method from June 1996 to January 1999, They were followed up for a minimum of two years. The operative technique includes fixation of the acromioclavicular joint, repair of coracoclavicular ligament and transfer of the anterolateral band of coracoacromial ligament. Results: The 20 patients were evaluated clinically using Kang's criteria. The satisfactory results obtained in 85%. The mean coracoclavicular interval ratio was decreased from 2.22 preoperatively to 1.07 postoperatively. At the time of two year follow-up, the mean ratio was 1.20. There was no definite complication such as re-dislocation of the joint. Conclusion: In above type 3 acromioclavicular dislocation, the modified Neviaser method provided the advantage of strong and stable fixation with a low complication rate. Therefore, it is thought to be one of the useful operative technique.

Optimal damping layout of the constrained viscoelastic damping layer on beam is identified with temperatures by using a gradient-based numerical search algorithm. An optimal design problem is defined in order to determine the constrained damping layer configuration. A finite element formulation is introduced to model the constrained layer damping beam. The four-parameter fractional derivative model and the Arrhenius shift factor are used to describe dynamic characteristics of viscoelastic material with respect to frequency and temperature. Frequency-dependent complex-valued eigenvalue problems are solved by using a simple re-substitution algorithm in order to obtain the loss factor of each mode and responses of the structure. The results of the numerical example show that the proposed method can reduce frequency responses of beam at peaks only by reconfiguring the layout of constrained damping layer within a limited weight constraint.

An impetus for reviving research in mathematical problem solving is the recent advance in methodological thinking, namely, the design experiment ([Gorard, S. (2004). Combining methods in educational research. Maidenhead, England: Open University Press.]; [Schoenfeld, A. H. (2009). Bridging the cultures of educational research and design. Educational Designer. 1(2). http://www.educationaldesigner.orgied/volume1/issue21]). This methodological approach supports a "re-design" of contextual elements to fulfil the overarching objective of making mathematical problem solving available to all students of mathematics. In problem solving, components critical to successful design in one setting that may be adapted to suit another setting include curriculum design, assessment strategy, teacher capacity, and instructional resources. In this paper, we describe the implementation, over three years, of a problem solving module into the main mathematics curriculum of an Integrated Programme school in Singapore which had sufficient autonomy to tailor-fit curriculum to their students.
