  • The purpose of this study was to investigate the relationship between delays in initiation and termination of tibialis anterior contraction through surface electromyographic (sEMG) analysis in adults with hemiplegia and healthy subjects and clinical assessment of lower-limb mobility. EMG activity of 6 long-term survivors of stroke and 5 healthy subjects was recorded during maximal isometric ankle dorsiflexion in 3 seconds beeper signals. It must be done as fast and forcefully as possible. Lower limb mobility was assessed with Modified Emory Functional Ambulation Profile (mEFAP). Delay in initiation and termination of muscle contraction was significantly prolonged in the affected lower limb relative to the unaffected limb. Termination of muscle contraction in the hemiplegic lower limb was significantly delayed than the initiation on the affected sides. Delay in initiation and termination of muscle contraction correlated significantly with a few range of mEFAP. Abnormally delayed initiation and termination of muscle contraction may contribute to hemiparetic lower limb mobility in hemiparetic patients. Consequently, this study showed that abnormal delay of initiation and termination of muscle contraction may contribute to hemiparetic lower limb mobility in adults with hemiplegia. Further studies are needed to demonstrate a treatment effect.

  • Due to liberalization in the early stage, mobile communications market has grown rapidly in the world. However, some dominant operators set higher termination call charges, and thus the market has been distorted and customer welfare has been reduced a lot. The regulation of mobile termination charges is one of key issues of most regulatory agencies in the world. According to the survey, the level of mobile termination charges are quite different from country to country. Why is it so different? This paper investigated the determinants affecting the mobile termination charges for 28 countries by considering country-specific, industry-specific, and regulatory-specific conditions. We found that some regulatory-specific conditions are the most important factors. The rate of pre-paid contract and period of regulation mostly affect the mobile termination charges.

  • T7 RNA polymerase also recognize intrinsic, hairpin-independent termination signal, a conserved 7-base pair sequence (ATCTGTT in the non-template stand) and U-rich sequence downstream of it. These intrinsic, hairpin-independent termination signal were commonly found in PTH and CJ termination sequences. There are two types of mutant T7 RNA polymerases recognizing sensitively(X3, X19, BG8) of insensitively (R173C) the intrinsic termination signals. We determined the T7 transcription activities of these mutants. Compared to wild-type, mutants X4, 19 and BG8 show highly reduced transcription activities (8%, 33%, 34%). On the other hand mutant R173C shows comparable transcription activity of wild-type (112%). Also transcription termination efficiencies at the PTH or CJ termination signals were determined by using mutant RNA polymerases. Temination of mutnats X4, X19 and BG8 are increased compared to wild-type. On the other hadn mutant R173C proceeds through PTH and CJ termination signals.

  • This paper introduces experimental investigates of an electrical accident of the distributing cable termination with simulated badness construction. We prepared two termination kites, one is built-up type, the other is heat contraction type. Also, we manufactured cable termination that have simulated defect by badness construction and measured their insulation characteristics such as ac (35kV, 1min) and impulse (95kV, $1.2{\times}50{\mu}s$) withstand test. The influence of defects such as thickness and the gap between stress-con of housing and semi-conductor on insulating properties of the termination have been studied. The thickness decrease of insulator decreases ac breakdown strength. Dielectric breakdown traces of insulator that is damaged by knife displayed other shape. The gap of between housing and semiconductor deteriorates dielectric strength of insulator seriously.

  • Flight termination system(FTS) is used to terminate safely the launch vehicle's flight when it faces an emergency situation by transmitting termination command from ground FTS. RCC standard IRIG tone method has been used widely for FTS commands method in foreign ranges and Naro Space Center, but this method has a weakness for security of command signal. Therefore RCC had studied more secured EFTS standard and chose CPFSK digital modulation method. This paper describes basic concept and types of FTS and FTS types which foreign ranges had applied and describes standardization of EFTS in the U.S. based on RCC EFTS study reports.

  • This paper presents the optimum termination method of a TEM Cell, which utilizes hybrid distributed termination resistor array networks. Current stream on the septum, and on the terminal end of a TEM Cell is analyzed by numerical analysis. By circuit analysis, the optimum resistor array network is designed based on the result of the analysis, which assures efficient power dissipation, and current stream traveling straight and uniform. Thermovision photos were taken for comparing the conventional termination network on which each resistor is arranged at regular intervals, with the suggested optimum termination network on which each resistor is arranged for current distribution. The comparison of the results of thermovision photos shows a good agreement with those obtained by numerical analysis.

  • Relationship marketing research has traditionally focused on the relationship among customer satisfaction, trust, and customer commitment, while assuming that the causal relationship of customer $satisfaction{\rightarrow}trust{\rightarrow}commitment$ is well understand. However, recently many scholars argue that customer satisfaction, trust, commitment can not explain long-term orientation fully, and suggest the need for more extensive researches investigating the determinants of long-term relational retention. The purpose of this study was to explained the relationship development process through the mediation effect of contact intensity and relationship termination cost between customer satisfaction and trust, and between trust and commitment, and an analysis the causal relationship among these variables. The results were as follows. First, the customer satisfaction had both direct and indirect effects on trust mediated by contact intensity. Second, the trust had both direct and indirect effects on commitment mediated by relationship termination cost. Third, the commitment influenced long-term orientation. Finally, the empirical results confirmed that the model add to the concept of mediation with contact intensity and relationship termination cost plays a strong, central role in explaining relationship development process between customer and fashion retail stores.

  • The effect of GnRH alone and concomitant with PMSG on the prevention of implantation. termination of pregnancy, and concentration of plasma progesterone were studied in pregnant rats. GnRH 50, 100 or 200 ug alone and concomitant with PMSG 25 or 50 IU were administered once on day 2 or 9 of gestation, respectively. Rats were autopsied on days 7 or 20. Administration of GnRH on day 2 did not result in the prevention of implantation and termination of pregnancy but resulted in termination of pregnancy administering on day 9. Administration of GnRM concomitant with PMSG on day 2 or 9 resulted in prevention of implantation and termination of pregnancy, but injection of GnRH 50 ug concomitant with PMSG 25 IU on day 9 had only one live fetus. Administration of GnRH alone and concomitant with PMSG on day 2 had no effect on the concentration of plasma progesterone determining on day 7. Administration of GnRH concomitant with PMSG on day 2 resulted in decrease of progesterone level determining on day 20 but GnRH alone was normal level. Administration of GnRH alone and concomitant with PMSG on day 9 resulted in decrease of the concentration of progesterone but was normal concentration administering GnRH 50 ug concomitant with PMSG 25 IU.
