  • The Electronic Commerce is expected as one of the most prospective industries in the 21th century, This research performed a survey and analysis is based on the results of the service quality model and previous research of the service quality in MIS. Service quality, one instrument developed by the marketing area, is provided as a possible measure of internet shopping mall, Service quality measures five service dimensions of tangible, reliability, responsiveness, assurance and empathy. The main purposes of this study are to develop an exploratory model based on service quality that can explain the factors of customer's perceived service quality and investigate how these factors are related to consumer satisfaction. The results of this survey are summarized as follows: (1) Reliability and responsiveness of internet shopping mall are evaluated as very important factors, (2) Service quality is an antecedent of consumer satisfaction, (3) Consumer satisfaction has a significant effect on purchase intentions.

  • In many epidemiological and medical studies, a number of cancer mortalities in categorical classification may be considered as having Poisson distribution with person-years at risk depending upon time. The cancer mortalities have been evaluated by additive or multiplicative models with regard to background and excess risks based on several covariances such as sex, age at the time of bombings, time at exposure, or ionizing radiation, cigarette smoking habits, duration of smoking habits, etc. An interest herein is to examine an additive, synergistic, or antagonistic relationship between radiation exposures and cigarette smoking habits for cancer mortalities. The results revealed a highly significant antagonistic in uence for cancer mortalities from all non-hematologic findings, lung and respiratory system with negative interaction between radiation exposures and cigarette smoking amounts.

  • In this paper, we find a method to improve ignitability using methanol which is prospective as an alternative fuel. The constant volume combuster is divided into main chamber and sub-cham¬ber. These two chambers are linked by an adapter which is shaped like a cup. We also compare CDI to HIS that is revised in our laboratory for making a scrutiny into the effects of ignition char¬acteristics. Besides, we analyze a flame propagation process in the main and sub-chamber through taking pictures 10, 000 frames per second by high speed camera at the state being fabricated quartz glass aside main and sub-chamber.

  • Recently combining regimen of minimal doses of chloral hydrate, hydroxyzine and midazolam is good in sedation of children. Midazoalm, water soluble benzdiazepine, has rapid onset and relatively short duration of action. And midazolam has prospective amnesic effect. With these advantages midazolam is popular in conscious sedation for children. This study was to reveal the dose-dependency of behavior and physiologic effects of submucosal midazolam. Sedation records were surveyed retrospectively, of which the patients admitted from April, 2005 to July, 2007. we assigned three groups according the dose of midazolam, 0.1 mg/kg, 0.2 mg/kg and 0.3 mg/kg, respectively and the behavioral evaluation was analyzed with Houpt scale statistically. Combined submucosal midazolam increased the success rate in sedation and the vital signs were stable during sedation.

  • To investigate the effects of the postural balance of TMJ using intraoral balancing appliance of functional cerebrospinal technique (FCST) combined acupuncture and manual medicine therapeutics in the treatment of congenital muscular torticollis. An idiopathic cervical dystonia case was managed with postural training with intraoral balancing appliance, combined with acupuncture and manual medicine therapeutics. Clinical assessment included radiography, Toronto Western Spasmodic Torticollis Rating Scale, and global clinical impression. Clinical improvement was observed over 5 months of treatment period. Clinical observational data on spasmodic torticollis provide an positive prospective for further investigation on the effect of FCST.

  • It is an important issue to explore classroom environments which are conducive to developing students' mathematical performance. This study explores the effects of different classroom environments (solution-demand and corresponding-time setting) on mathematical performances. Fourteen and eighteen prospective teachers were required to prove a task under different conditions respectively: a) Cognitive demand of multiple-solution corresponding time of three hours, and b) Cognitive demand of a right solution corresponding time of 20 minutes. We used SOLO as the assessment tool for mathematical performance from quality perspective. Significant differences were found in the quantity and quality of mathematical performance. The regular environment focusing on speed and accuracy were found to be directly linked to low levels of performance. The findings above provide implications to the cognitive benefits of multiple-solution demand and corresponding time setting.

  • To investigate phytotoxic substances in some donor plants and their biological activities, seed germination and seedling growth of receptor plants were examined at different concentrations of aqueous extracts and essential oils of the donor plants. Germination of some receptor species was inhibited by the extracts, while seedling growth was decreased to a lesser degree than in the germination test. Germination, seedling growth and dry weight growth of Achyranthes japonica grown in pot were proportionally inhibited by the extracts. Volatile substances emitted some donor plants caused inhibitory effects in the germination and seedling growth of the receptor species. Essential oil of the plants extracted by Karlsruker's apparatus Inhibited growth of microorganisms, callus growth and root hair development of receptor plants. The cortical cells at the root tips of Latuca sativa treated with essential oils showed contraction of the cytoplasm, resulting in plasma membranes becoming detached from the cell walls and the cells metamorphosing irregularity. Accumulation of lipid granules Inside contracted cytoplasm and degeneration of mitochondrial cristae were also observed. The GC/MS method was employed for analysis and identification of allelochemicals from donor plants. Sixty-one chemical substances such as camphene, cineole etc. were identified from essential oils of Artemisia argyi.

  • Objectives : Far-infrared (FIR) lights have been investigated for sleep quality intervention. We sought to measure the advantageous effects of FIR in sleep using polysomnographic data as the objective outcomes. Methods : The ten healthy volunteers were enrolled in a single-center, prospective, patient-blind, single-arm trial. Individuals slept on a sham mattress and a FIR emitting mattress with polysomnography for one night each. Results : Sleep efficiency showed an increasing trend but was not statistically significant. PSQI-K significantly decreased (p=0.013). The latency to REM of the baseline was shorter than that of the intervention (p=0.008). Though there was no statistical significance, Stage N1 and N2 were shortened, and Stage N3 was prolonged after the intervention compared to the baseline. Conclusions : The FIR-emitting mattresses improved sleep quality on self-reported insomnia. We suggested the candidate for the markers altered by the FIR therapy, such as the normalization of REM latency and increased N3 sleep.

  • Background: Wet cupping (WC) is an efficient and cost-effective technique for removing metabolic waste from the bloodstream via the skin. The study aimed to examine the effect of WC on cholesterol levels including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in a Sudanese population. Methods: In this prospective cross-sectional study, 30 participants undergoing regular WC therapy were enrolled. Blood samples collected twice: pre-WC therapy (case group) and 10-14 days afterward (controls). Results: Of the participants, 56.67% were male and 43.33% were female, aged 24-69. Pre-WC TC and LDL-C levels were significantly higher than the post-WC control group (p = 0.001). Conversely, HDL-C levels decreased significantly in the pre-WC cases compared to controls (p = 0.001). No significant sex-based difference in mean cholesterol levels (p > 0.05). Conclusions: After WC, males and females experienced significant reductions in TC and LDL-C, and significant increase in HDL-C.
