Purpose – The purpose of this paper is to present an integrative approach for the problem of service capacity design for the ground crew at the airport check-in counters. Design/methodology/approach – Using data collected from the airport check-in counters, several characteristics of the service demand were studied. First, many service time-dependent operating characteristics are addressed over a specified time window to evaluate the problems from the current ground crew allocation. Second, a linear programming model is developed to determine the optimal number of check-in counters to open over the specified time window based on the case study. In addition, sensitive analysis is conducted to further explore the dependency effect of the factors as well as improve the model. Third, the shift adjustment of the ground crew allocation is provided so as to satisfy the given service demand. Findings – Numerical results indicated the effectiveness in the improvement of the human resource utilization of the proposed approach. The superiority of performance is illustrated in terms of less counters to be opened and decreased daily working hours. Originality/value – The study is novel by applying the integrated approach so as to design a proper service capacity and thus the service supply and demand can be balanced.
BACKGROUND Fistula-in-ano is an abnormal tunnel formation linking the anal canal with the perineum and perianal skin. Multiple imagining methods are available to evaluate it, among which magnetic resonance imaging (MRI) is the most advanced noninvasive preoperative method. However, it is limited in its visualization function. AIM To investigate the use of intraluminal MRI for perianal fistulas via a novel direct MRI fistulography method. METHODS We mixed 3% hydrogen peroxide (HP) with gadolinium for HPMRI fistulography, retrospectively analyzing 60 cases of complex/recurrent fistula-in-ano using physical examination, trans-perineal ultrasonography (TPUS), low-spatial-resolution MRI, and high-resolution direct HPMRI fistulography. We assessed detection rates of fistula tracks, internal openings, their relationship with anal sphincters, and perianal abscesses using statistical analyses, including interobserver agreement (Kappa statistic), and compared results with intraoperative findings. RESULTS Surgical confirmation in 60 cases showed that high-resolution direct HPMRI fistulography provided superior detection rates for internal openings (153) and fistula tracks (162) compared to physical exams, TPUS, and low-spatial-resolution MRI (Z > 5.7, P < 0.05). The effectiveness of physical examination and TPUS was also inferior to that of our method for detecting perianal abscesses (54) (Z = 6.773, 3.694, P < 0.05), whereas that of low-spatial-resolution MRI was not significantly different (Z = 1.851, P = 0.06). High-resolution direct HPMRI fistulography also achieved the highest interobserver agreement (Kappa: 0.89, 0.85, and 0.80), while low-spatial-resolution MRI showed moderate agreement (Kappa: 0.78, 0.74, and 0.69). TPUS and physical examination had lower agreement (Kappa range: 0.33-0.63). CONCLUSION High-resolution direct HPMRI fistulography enhances the visualization of recurrent and complex fistula-in-ano, including branched fistulas, allowing for precise planning and improved surgical outcomes.
The unearthed literature provided rich and precious materials to the culture of health preservation teaching. The thinking of “correspondence between man and nature” and opposition and mutual basement of Yinyang and imitation combined with performance were the dominant ideas and important component parts of the culture of health preservation teaching. Students can have a better understanding of the Chinese traditional culture and inheritance on traditional culture in order to go into it by learning the culture of health preservation.
A prominent cause of cancer-related fatalities with a poor prognosis is lung adenocarcinoma (LUAD). KIF5A, a crucial member of the kinesin superfamily, is linked to drug resistance in malignancies. This work aims to investigate the mechanism of KIF5A in docetaxel (DTX) resistance in LUAD cells. The results of bioinformatics analysis, qRT-PCR and western blot analysis show that KIF5A, which is involved in the glycolysis pathway, is highly expressed in LUAD and is positively correlated with glycolysis-related genes. We further verify that silencing of
Abstract To address organic dye pollution and agricultural waste comprehensive utilization, the biochar (ZB) was prepared using Rosa roxburghii residue as the material for preparation. Three modified biochars (ZBO, ZBS, and ZBH) were created using NaOH, Na 2 S, and H 3 PO 4 as modifying agents. The morphology, structure, pore size, and elemental composition of biochars were characterized and analyzed by a combination of FTIR, SEM-EDS, and N 2 adsorption–desorption techniques. Furthermore, the adsorption performance of the as-prepared biochars was investigated in the adsorption of RhB and MB dye process. The experimental findings showed that adsorption equilibrium for these dyes was achieved in 180 min. Moreover, the dye adsorption on biochars followed a pseudo-second-order kinetic equation. For the biochar (ZB), the Langmuir equation proved to be more appropriate than the Freundlich equation. In contrast, the Freundlich equation was more apt for the modified biochars. More importantly, Pearson's correlation analysis revealed that the adsorption rate and capacity of RhB positively correlated with the specific pore volume, t-plot micropore area, and BET surface area, but a negative one with the pore size. The MB adsorption showed the opposite correlations. This study reveals a novel biochar for adsorbing organic dyes, which provides a strategy for the treatment of Rosa roxburghii residue.
Most research suggests professional development improves teachers’ knowledge and pedagogy and enhances teachers’ confidence to facilitate a positive attitude about student learning. This study attempted to investigate the connection between teacher professional development program and students’ Learning. This study took Readers’ Theater Teaching Program (RTTP) for professional development as an example to inquiry how participants applied their new knowledge and skills learned from RTTP to their teaching practice and how the impact influenced students’ reading fluency. This study was a two-year project. In the first year, this study focused on designing and implementing RTTP and evaluating participants’ satisfaction of RTTP, what they learned and how they applied it to design their English reading curriculum. In the second year, the study adopted quasi-experimental design approach and evaluated how participants RT instruction influenced their students’ reading fluency. The participants in this study composed two junior high school English teachers and their students. Data was collected from a number of different sources including teaching observation, semi-structured interviews, teaching diary, teachers’ professional development portfolio, pre/post RT content knowledge tests, teacher survey, and students’ reading fluency tests. The results indicated that teachers learned more RT script writing than other specific contents and hold a positive attitude toward RT instruction and considered it as a very wonderful strategy to meet a variety of needs. All of the experimental group students had a big progress in reading fluency after RT instruction. The evidences from this study indicated that RT English instruction significantly influenced students’ reading fluency and classroom climate.
<p>For the past two decades, language center in almost every university in Taiwan has attempted to implement the notion of independent learning through online learning resources. To many student learners, the easy and inexpensive access of Internet has made innumerable learning resources provided by language centers available for self-access language learning. However, whether students have cultivated self-access learning ability through appropriate learning practices online is the main point that school authorities are eager to find out. In order to know the effectiveness of self-access learning in online resource-based context, many universities take different ways to evaluate students’ achievement. Since evaluations of self-access learning are important for student learners to know if they gradually and individually move towards autonomy, their assessments must be more objective. The purpose of this one-year study, therefore, was to examine whether selected online learning resources and evaluation methods affected students’ self-access learning attitudes and whether students cultivated self-access learning ability and learned successfully in online resource-based context. To gather the data, one hundred and twelve non-English majored students from a university of Southern Taiwan were recruited as samples and two types of objective evaluation, an assessment test and online learning records, were used in this study. Major findings indicated that language students’ self-access learning attitudes improved and they did make progress in online resource-based context. However, the training for students toward self-access learning needs to be strengthened. Suggestions were also included in this paper.</p>
