  • This study aims to examine genetics problem-solving processes of high school students with different learning approaches. Two second graders in high school participated in a task that required solving the complicated pedigree problem. The participants had similar academic achievements in life science but one had a deep learning approach while the other had a surface learning approach. In order to analyze in depth the students' problem-solving processes, each student's problem-solving process was video-recorded, and each student conducted a think-aloud interview after solving the problem. Although students showed similar errors at the first trial in solving the problem, they showed different problem-solving process at the last trial. Student A who had a deep learning approach voluntarily solved the problem three times and demonstrated correct conceptual framing to the three constraints using rule-based reasoning in the last trial. Student A monitored the consistency between the data and her own pedigree, and reflected the problem-solving process in the check phase of the last trial in solving the problem. Student A's problem-solving process in the third trial resembled a successful problem-solving algorithm. However, student B who had a surface learning approach, involuntarily repeated solving the problem twice, and focused and used only part of the data due to her goal-oriented attitude to solve the problem in seeking for answers. Student B showed incorrect conceptual framing by memory-bank or arbitrary reasoning, and maintained her incorrect conceptual framing to the constraints in two problem-solving processes. These findings can help in understanding the problem-solving processes of students who have different learning approaches, allowing teachers to better support students with difficulties in accessing genetics problems.

  • This Study was to investigate elaborated research themes and direction through specifying the problems of clinical practice education and looking for the direction of improvement. It was in the basis of the viewpoint of the educators that professors and therapists who were the subjects of this study. Perform this study, the 15 colleges' professors and the 55 hospitals' therapists was made up questionnaire, and the data was analysing by Chi-square test and percentage. The results were as follow : ${\cdot}$ In a personal history among the general qualities, professors have little clinical practice history(l-5 years, 53.3%), and therapists have little lecture career(1-5 years, 43.6%, have no 49.0%), ${\cdot}$ The 78.6% subjects were unsatisfied of clinical practice systems. ${\cdot}$ The correlation between clinical history, school career and lecture career and the satisfaction level of clinical practice systems has no(P<.005), ${\cdot}$ The subjects were agreed to that clinical practice curriculum should be changed(67.1%), reinforced(82.9%), and specified(90.0%). ${\cdot}$ The clinical practice credits are 11 points averagely. ${\cdot}$ In the clinical practice curriculum, it made no difference in the practicum of diseases, modality, and the therapeutic techniques between professors and therapists. ${\cdot}$ The 100% professors said that the practicum of the patients' assessment is necessary, and the 63.6% therapists were training for that. ${\cdot}$ The 66.7% professors said that the practicum of the clinical psychology is necessary, and only the 20.0% therapists were training for that. ${\cdot}$ The 93.3% professors said that the practicum of the patients' management is necessary, and the 50.9% therapists were training for that. ${\cdot}$ The 66.7% professors said that the practicum of the medical ethics is necessary, and the 34.5% therapists were training for that. ${\cdot}$ The 46.7% professors said that the practicum of the hospital administration is necessary, but the 54.5% therapists have not training. ${\cdot}$ The 33.3% professors said that the practicum of the pharmacology is necessary, but the 81.8% therapists have not training. ${\cdot}$ The 86.7% professors said that the practicum of the patient's education is necessary, and the 43.6% therapists have training. ${\cdot}$ The 66.7% professors said that the practicum of the prosthesis and brace is necessary, but the 14.5% therapists have not training. ${\cdot}$ The 60.0% professors said that the practicum of the exercise prescription is necessary, but the 25.5% therapists have not training. ${\cdot}$ The 53.5% professors said that the practicum of the emergency treatment is necessary, but the 52.7% therapists have not training. ${\cdot}$ Drawing up the plan about the curriculum of clinical practice, the professors (46.7%) were agreed to national master plan framing by an expert advisor, but the therapists (58.2%) said that the plan that make the most of hospitals' characteristics should be specified. ${\cdot}$ It was found that a clinical special therapists(54.5%) was good as a person in charge of clinical practice education, in that each therapist's own good time (34.5%) was. ${\cdot}$ It made use of the form framing by college(40.0%) as the clinical practice textbook, the form framing by hospital (42.9%) and each therapist(22.9%) as the plan, and the form framing by college (74.3%) as the measurement. ${\cdot}$ The most difficult point in clinical practice education was the lacks of the theory-praciticum linkage(78.2%). ${\cdot}$ It was found that the period of clinical practice was in the second semester-third grade (40.0%) and the desirable period was in the first semester-third grade(50.0%). ${\cdot}$ Professors (53.3%) were agreed that the desirable clinical practice duration was from four months to six months(60.0%), and the therapists (60.0%) were agreed that from one month to three months. ${\cdot}$ This study presented the lacks of rearing the experts, the lacks of cultural education, and the lacks of the theory-clinical practice linkage. There were need to develop the systematic programs, clinical practice textbooks, the measurements and the special hospital for clinical practice. And it was need to reduce the gab between of the hospitals for clinical practice, to cut down the costs. and to improve the labour conditions of leaders. In view of this findings, it takes notice of that both professor and therapist were dissatisfied at the present clinical practice systems. These results point out the problems of clinical practice systems, and do not make expect to us the successive and positive clinical practice. The general, specific and intensive plan about the problems and the direction of improvement that establishing the level of hospital for clinical practice and physiotherapy can be elaborated.

  • The purpose of the research is to investigate of diesel spray combustion for simultaneously reduce way NOx and PM. The pressure diesel injection were done into intermediates that are generated by very lean DME HCCI combustion using a RCM. The concentration of intermediate could not be directly measured; we estimated it by CHEMKIN calculation. DME HCCI characteristic is surveyed. Validations of the CHEMKIN calculation were confirmed pressure rise of an experiment and pressure rise of a calculation. Using a framing streak camera captured two dimensional spontaneous luminescence images from chemical species at low temperature reaction(LTR) and high temperature reaction (HTR). Also, the combustion events were observed by high-speed direct photography, the ignition and combustion were analyzed by the combustion chamber pressure profiles.

  • Details are given of a cold-formed steel portal framing system that uses simple bolted moment-connections for both the eaves and apex joints. However, such joints function as semi-rigid and, as a result, the design of the proposed system will be dominated by serviceability requirements. While serviceability is a mandatory design requirement, actual deflection limits for portal frames are not prescribed in many of the national standards. In this paper, a review of the design constraints that have an effect on deflection limits is discussed, and rational values appropriate for use with cold-formed steel portal frames are recommended. Adopting these deflection limits, it is shown through a design example how a cold-formed steel portal frame having semi-rigid eaves and apex joints can be a feasible alternative to rigid-jointed frames in appropriate circumstances.

  • Beginning in the late 19th century, construction of skyscrapers spread throughout Chicago, New York City, and then the world as demand of space in buildings and increase of cost of land. With this change curtain wall systems have evolved to be more visually complex; these unique profiles of the skyscraper became powerful images and symbols of our cities. A curtain wall is defined as usually aluminum-framed wall containing in-fills of glass and metal panels. The framing is attached to the building structure and does not carry the floor or roof loads of the building.

  • In the design of ductile moment-resisting frames (DMRFs) following the strong column-weak beam dsign philosophy, it is desirable that the joint and column remain essentially elastic in order to insure proper energy dissipation and lateral stability of the structure. The joint has been identified as the "weak link" in DMRFs because any stiffness or strength deterioration in this region can lead to substantial drifts and the possibility of collapse due to P-delta effects. Moreover, the engineer is faced with the difficult task of detailing an element whose size is determined by the framing members, but which must resist a set of loads very different from those used in the design of the beams and columns. Four 2/3-scale beam-column-slab joint assemblies were designed according to existing code requirements of ACI 318-89, representing interior joints of DMRFs with reinforced high strength concrete. The influence on aseismic behavior of beam-column joints due to monolithic slab, has been investigated.estigated.
