This work discusses simulation results for the fuzzy logic controller tested the project“Fuzzy Ramp Metering Algorithm Implementation.”The performance objectives were, in order of priority, to maximize total vehicle-miles, maximize mainline speeds, and minimize delay per vehicle while maintaining an acceptable ramp queue. In the fuzzy logic controller, the sensors from the on-ramps were helpful in maintaining reasonable ramp queue and mainline congestion because it considered these factors simultaneously. Each metered ramp had a parameter input file, which allowed the controller to be modified without recompiling the software. Consequently, maintenance costs should be minimal.

This phenomenological study aims at exploring the role of family in promoting, maintaining, and developing job activities of women with acquired physical disabilities. As a result of in-depth interviews with 8 women with physical disabilities, 6 theme clusters and 14 sub-themes have appeared. Participants have vividly revealed their experiences with regard to the various support and help of their family. They were provided physical, emotional and financial supports which helped at great extent to overcome the anger and loss resulted from the acquired disabilities. Although most of the participants have experienced failure in job finding several times, they have at last succeeded in it by the consistent help of their family. In particular, the support and help given from the family were substantial and specific which promoted maintaining and developing their career. Therefore the participants could obtain more confidence in themselves and this made the participants to speak for themselves. Although the family roles for the job finding and maintaining of the participants are played in various ways which is positive, effective and specific, there remains some significant problems and limitations. Participants expressed their uncomfortableness in opening their most in-depth thinking and emotions to their family. They have also experienced a great deal of difficulties in maintaining job because of the housework load and child bearing work which is mainly regarded by the family members as the woman's(participant's)duties. In addition to this, sexual needs and sexual identity of the participants are neither recognized nor dealt with seriously in family, The participants also mentioned about the inequal relationships and their self-consciousness among family member as well as the lack of career guidance role of the family. Based on these research findings, we have made a number of suggestions to promote the positive roles and overcome the limited roles of the family.

Objective: The aim of this study is to develop an office chair enabling to keep working at reclined sitting posture. Background: Sedentary workers are supposed to change the posture frequently during long hours of sitting. A reclined sitting position has been recommended to reduce disc pressure. But slumped sitting posture caused by the buttock sliding forward without any adjustment of back reclining is commonly observed. The worker seems to have tendency to change the sitting posture maintaining working condition. We assumed the reason to be their hands movement away from the working space when tilting backward. Method: Slide mechanism allowing seat to move forward was designed to maintain the hand position in working space during reclining. A prototype was manufactured and tilting motion was analyzed using motion capture system. Four experiment chairs were tested including the manufactured prototype chair and three other commercial chairs. Results: A backward movements of the hand position were 13.0mm, 101.7mm, 156.1mm and 139.3mm at the prototype chair, compared to chair B, chair C and chair D, respectively. And the movement was remarkably small at the prototype chair. Conclusion: The developed seat sliding chair allows back tilting maintaining hand position at working space. We expect the user tilting back more often than normal tilting chair during seated work. But further investigation is required to figure out the effectiveness of the developed chair using prolonged working hours. Application: The developed office chair directly affects commercialization.

In this paper, we demonstrated a polarimetric fiber pressure sensor using a polarization-diversity-loop-based Sagnac interferometer(PDLSI) composed of polarization-maintaining fiber(PMF) and a fiber Bragg grating(FBG). In order to compare the pressure sensitivity for various kinds of PMF, three kinds of bow-tie PMF were employed as sensor heads. The maximum pressure sensitivity was measured as approximately -15.07nm/MPa, and an R2 value to represent sensor linearity was measured as ~0.992 at the sensor system using corresponding PMF over a pressure range of 0-0.3MPa. An FBG was utilized and located adjacent to the PMF segment for compensating temperature-induced errors in the measurement of pressure. The pressure sensitivity of the proposed sensor was improved by approximately four times compared with the previously reported pressure sensor based on polarization-maintaining photonic crystal fiber.

In this paper, a new scheme of a boosted voltage generator (BVG) is designed for low powr DRAM's. The designed BVG can supply stable $V_{pp}$ using a new circuit operting method. This method controls charge pumping capability by switching the supply voltage and ring oscillator frequency of driving circuit, so the BVG can save area and reduce the powr dissipation during $V_{pp}$ maintaining period. The charge pumping circuit of the BVG suffers no $V_{T}$ loss and is to be applicable to low-voltage DRAM's. $V_{pp}$ level detecting circuit can detect constant value of $V_{pp}$ against temperature variation. The level of $V_{pp}$ varies -0.55%~0.098% during its maintaining period. Charge pumping circuit can make $V_{pp}$ level up to 2.95V with $V_{cc}$ =1.5V. The degecting level of $V_{pp}$ level detecting circuit changes -0.34% ~ 0.01% as temperature varies from -20 to 80.deg. C. The powr dissipation during V.$_{pp}$ maintaining period is 4.1mW.W.1mW.

The effects of Eurycoma longifolia Jack were studied in maintaining mating behavior of sexually experienced castrated male rats after dosing them with 500 mg/kg daily of E. longifolia Jack for 10 days prior to test and later continued for two weeks where the rats were then castrated. The similar dosage was then continued for 12 weeks post-castration. However, $400\;{\mu}g/day$ of testosterone was administered subcutaneously on the day of castration and lasted for 6 weeks post-castration but later raised to $800\;{\mu}g/day$ until 12 week post-castration. Tests were conducted weekly from 2-6 weeks and 8-12 weeks post-castration. Results showed that all the experimental male rats exhibited mating behavior before castration. Further results also indicated that E. longifolia Jack successfully maintained mating behavior but less than precastration level from 2-6 weeks and later increased from 8-12 weeks post-castration. Similarly, $400\;{\mu}g/day$ of testosterone was effective in maintaining mating behavior from 2-6 weeks post-castration. However, $800\;{\mu}g/day$ of testosterone managed to return the male rats to the precastration level with all male rats exhibited mating behavior from 8-12 weeks post-castration. Further results also indicated that testosterone significantly increased the penis weights (p < 0.05) as compared to the E. longifolia Jack. In conclusion, this study shows that E. longifolia Jack continued to maintain mating behavior of sexually experienced castrated male rats, giving further evidence of the folkuse of this plant as aphrodisiac.

The purpose of our study is to evaluate the ability of nickel-titanium(NiTi) files in maintaining the original curvature of a curved root canal during canal preparation. Curved canals on translucent resin blocks were prepared with NiTi and stainless steel files, and they were placed at the platform which can reproduce the same position. The unprepared and prepared canal forms were accurately compared by double exposure technique of photography. By finite element methods we also analyzed stress distributions of NiTi and stainless steel files in a curved canal. The results were as follows : 1. NiTi files were excellent in maintaining the original curvature of a curved canal than stainless steel files after canal preparation. 2. The results of canal preparation with these files were well verified by the analysis of stress distributions using finite element methods.
