ACTION RESEARCH ON STUDENTS' CREATIVE INVENTIONS IN VOCATIONAL HIGH SCHOOL
Because the bicycle lacks lighting equipment, there is no indicator light when steering and braking, thus making it is easy to cause a rear vehicle collision and form a casualty, especially at night. In view of this, this study focused on the safety of bicycles at night, taking vocational high school students, using the existing equipment of the school, combined with relevant curriculum theory and practice, creative thinking and production of "Bicycle safety display device", the LED projection lamp installed in the back seat, with the back of the bicycle rider as the projection screen, can display the enlarged pattern of left and right turn and brake, so that the rear vehicle can be clearly identified to reduce the incidence of accidents. The conclusions of this study are as follows:(1)The study found that the production of the "Bicycle Safety Display Device" enhanced students' understanding and application of relevant courses; (2) The study found that the production of "Bicycle Safety Display Device" enhanced the student's circuit design and production capabilities; (3) Through participation in the project, the students generally came to believe that the production of the "Bicycle Safety Display Device" can unite the team's centripetal force and contribute greatly to the improvement of cooperative learning, and problem solving and innovative invention capabilities; (4) The finished product of this study is useful for the night driving safety of the bicycle
Action to Acquisition—Boost Students’ English Learning Motivation with Filmmaking Project
In Taiwan, English is more a major subject matter for student to “study” in school rather than a language for people to use in real life situations. Under the situation, students tend to have lower learning motivation when come to English classes, especially in higher academic settings, like universities. In order to boost students’ learning motivation as well as to encourage their productivity and creativity at the same time, a preliminary action research was conducted by two researchers collaboratively whereas one researcher is the instructor simultaneously. The major focus of the action research is concerning the application of “filmmaking” as a potentially effective tool to attract students into the classroom activities as well as the lesson content. For four semesters successively, a semester project has been assigned to 10 classes. By the end of each semester, reflections from students and the instructor were collected for refining purpose. From the students’ reflection and random interviews, an interesting comment appeared repeatedly: although the filmmaking project required them much effort and time, the results brought them the excessive fun and sense of accomplishment
Q-enhanced fold-and-bond MEMS inductors
This work presents a novel coil fabrication technology
to enhance quality factor (Q factor) of microfabricated inductors
for implanted medical wireless sensing and data/power transfer
applications. Using parylene as a flexible thin-film device
substrate, a post-microfabrication substrate folding-and-bonding
method is developed to effectively increase the metal thickness of
the surface-micromachined inductors, resulting in their lower
self-resistance so their higher quality factor. One-fold-and-bond
coils are successfully demonstrated as an example to verify the
feasibility of the fabrication technology with measurement results
in good agreements with device simulation. Depending on target
specifications, multiple substrate folding-and-bonding can be
extensively implemented to facilitate further improved electrical
characteristics of the coils from single fabrication batch. Such Q-enhanced
inductors can be broadly utilized with great potentials
in flexible integrated wireless devices/systems for intraocular
prostheses and other biomedical implants
Noninvasive prediction of Blood Lactate through a machine learning-based approach.
We hypothesized that blood lactate concentration([Lac]blood) is a function of cardiopulmonary variables, exercise intensity and some anthropometric elements during aerobic exercise. This investigation aimed to establish a mathematical model to estimate [Lac]blood noninvasively during constant work rate (CWR) exercise of various intensities. 31 healthy participants were recruited and each underwent 4 cardiopulmonary exercise tests: one incremental and three CWR tests (low: 35% of peak work rate for 15 min, moderate: 60% 10 min and high: 90% 4 min). At the end of each CWR test, venous blood was sampled to determine [Lac]blood. 31 trios of CWR tests were employed to construct the mathematical model, which utilized exponential regression combined with Taylor expansion. Good fitting was achieved when the conditions of low and moderate intensity were put in one model; high-intensity in another. Standard deviation of fitting error in the former condition is 0.52; in the latter is 1.82 mmol/liter. Weighting analysis demonstrated that, besides heart rate, respiratory variables are required in the estimation of [Lac]blood in the model of low/moderate intensity. In conclusion, by measuring noninvasive cardio-respiratory parameters, [Lac]blood during CWR exercise can be determined with good accuracy. This should have application in endurance training and future exercise industry
