  • The transportation problem (TP) is one of the earliest and the most significant implementations of linear programming problem (LPP). It is a specific type of LPP that mostly works with logistics and it is connected to day-to-day activities in our everyday lives. Nowadays decision makers (DM's) aim to reduce the transporting expenses and simultaneously aim to reduce the transporting time of the distribution system so the bi-objective transportation problem (BOTP) is established in the research. In real life, the transportation parameters are naturally uncertain due to insufficient data, poor judgement and circumstances in the environment, etc. In view of this, neutrosophic bi-objective transportation problem (NBOTP) is introduced in this paper. By introducing single-valued trapezoidal neutrosophic numbers (SVTrNNs) to the co-efficient of the objective function, supply and demand constraints, the problem is formulated. The DM's aim is to determine the optimal compromise solution for NBOTP. The extended weighted possibility mean for single-valued trapezoidal neutrosophic numbers based on [40] is proposed to transform the single-valued trapezoidal neutrosophic BOTP (SVTrNBOTP) into its deterministic BOTP. The transformed deterministic BOTP is then solved using the dripping method [10]. Numerical examples are provided to illustrate the applicability, effectiveness and usefulness of the solution approach. A sensitivity analysis (SA) determines the sensitivity ranges for the objective functions of deterministic BOTP. Finally, the obtained optimal compromise solution from the proposed approach provides a better result as compared to the existing approaches and conclusions are discussed for future research.

  • This study investigated how the image congruity of social commerce and fashion brand types affects purchase intention and how trust and price sensitivity moderate this relationship. National brands, private brands, and non-brands were used as brand types in the present study. The online survey method was used to gather the data, and 232 data samples were analyzed. The results of the research were as follows. Consumers perceived greater image congruity between social commerce and non-brands, followed by private brands and national brands. The significant perception differences were examined by comparing the mean values. There was a significant positive effect of image congruity of social commerce and non-brands on purchase intention. However, insignificant effects were found for image congruity between social commerce and private brands and national brands. In addition, trust and price sensitivity positively predicted social commerce purchase intention. A significant moderating effect of trust was found on the relationship between purchase intention and image congruity of social commerce and non-brands. A moderating effect of price sensitivity was found on the relationship between purchase intention and image congruity of social commerce and private brands. The findings of the present study offer valuable insights into social commerce concerning implementing diverse fashion brands as well as academic and practical implications.

  • Purpose: Several screening tools have been developed to identify sarcopenia in rural community-dwelling older adults. We aimed to compare the diagnostic accuracy of two such tools, namely the SARC-F and SARC-CalF assessments. Methods: This cross-sectional study on 388 community-dwelling older adults comprised 254 women and 134 men with a mean age of 77.8 ± 6.26 year in Korea. We assessed muscle mass, muscle strength, and physical performance using a bioimpedance analysis device, hydraulic hand dynamometer, and 4 m gait speed test, respectively. Three widely-used diagnostic criteria [the Asian Working Group for Sarcopenia (AWGS), European Working Group on Sarcopenia in Older People, and the International Working Group on Sarcopenia] were applied. Sensitivity and specificity analyses were performed on the SARC-CalF and SARC-F tests. We used receiver-operating characteristic curves and the area under the curves (AUCs) to compare the diagnostic accuracy of the assessments with regard to sarcopenia. Results: An analysis using four sets of diagnostic criteria showed that the prevalence of sarcopenia was 27.6% to 41.0%. Using the AWGS 2019 criteria as a reference standard, the SARC-CalF had a sensitivity of 83.02% and a specificity of 53.71% in the entire study population, whereas the SARC-F had a sensitivity of 79.87% and a specificity of 41.92%. The AUCs for the SARC-CalF and SARC-F tests were 0.725 (95% confidence interval 0.678-0.769) and 0.645 (95% confidence interval 0.595-0.693), respectively (p<001). In the analyses using the other three diagnostic criteria, similarity was also confirmed. Conclusion: SARC-CalF showed better sensitivity than did SARC-F when diagnosing sarcopenia in rural community-dwelling older adults. Further studies are needed to verify this finding in different populations.

  • Objective : Panic disorder is a chroni, debilitating illness, and has been known to be affected by high anxiety sensitivity and a poor quality of life. We examined if 12 weeks of pharmacotherapy with escitalopram could affect anxiety sensitivity, quality of life, and general disability in patients with panic disorder. Method : We enrolled 27 patients who met the DSM-IV-TR criteria for panic disorder, with or without agoraphobia, and completed 12 weeks of escitalopram treatment. We enrolled 29 normal control subjects who were matched for age and sex compared with the panic patients. All subjects were assessed using the Hamilton Rating Scale for depression (HAM-D), Hamilton Rating Scale for Anxiety (HAM-A), Panic Disorder Severity Scale (PDSS), Anxiety Sensitivity Index-Revised (ASI-R), WHO quality of life assessment (WHO-QOL) and Sheehan Disability Scale (SDS) before and after 12 weeks of treatment. Result : Panic disorder patients had a higher Anxiety sensitivity, a poorer Quality of life, and significant disability than normal control subjects at baseline. After the treatment, Panic disorder patients showed significant improvement in the severity of panic symptoms in terms of the HAM-A p<0.001), HAM-D (p<0.001) in addition, the reached a remission state in terms of the PDSS score. They also showed significant improvement in the ASI-R (p<0.001), WHO-QOL (p<0.001) and SDS (p<0.001), but mean scores of the ASI-R, WHO-QOL and SDS in panic disorder patients were did not reach normal levels. Conclusion : This study suggests that 12 weeks of pharmacotherapy with escitalopram could improve anxiety sensitivity, quality of life, and disability in panic disorder patients, although their anxiety sensitivity, quality of life and disability were not yet normalized after short-term pharmacotherapy. Thus, long-term pharmacotherapy may be necessary for panic disorder patients in order to get an optimal clinical response in terms of anxiety sensitivity, quality of life, and general disability.

  • Alternative binary offset carrier (AltBOC) signals can be approximated by four synchronized direct sequence spread spectrum (DSSS) signals, each pair of which is a quadrature phase shift keyed (QPSK) signal at a different frequency. Therefore, depending on the strength of an incoming AltBOC signal, an acquisition technique can reduce the mean acquisition time (MAT) by searching the four DSSS signals asynchronously; the search for each of the four DSSS signals can start at one of the evenly separated hypotheses on the two-dimensional hypothesis space. And detection sensitivity can be improved by multiple levels when different numbers of search results for the same hypothesis are combined. In this paper, we propose a fast AltBOC acquisition technique that has an asynchronous search strategy and efficiently utilizes the output of the four search results to increase the sensitivity level when sensitivity improvement is needed. We provide a complete theoretical analysis and demonstrate with numerous Monte Carlo simulations that the MAT of the proposed technique is much smaller than conventional AltBOC acquisition techniques.

  • Purpose: This study was conducted to exam the effect of a biomedical ethics education program on the consciousness of biomedical ethics, moral sensitivity and critical thinking disposition in nursing students. Method: A quasi-experimental research design and repeated measured ANOVA were used. The participants were divided into an experimental group (n=148) and a control group (n=169). Each group underwent freshman university nursing training in two major cities. The mean age was 21.3 years and the time of providing the biomedical ethics education program was 15 hours for 15 weeks. The experimental group was provided biomedical ethics education during the semester; the control group was not provided any biomedical ethics education. Results: The consciousness of biomedical ethics was increased significantly in the experimental group (t=-4.724, p<.001). Moral sensitivity was increased significantly in the experimental group (t=-2.021, p<.004). Critical thinking disposition was increased significantly in the experimental group (t=-5.775, p<.001). Conclusion: The results of the study show that providing biomedical ethics education to nursing students is an effective method to increase the consciousness of biomedical ethics, moral sensitivity and critical thinking disposition.

  • We present the optical design and a sensitivity analysis for a wide field of view (FOV) instrument operating at UV and IR wavelengths. The ongoing investigation is performed in collaboration with Omnisys Instruments (Sweden) and focuses on a telluric-limb-viewing instrument that will fly in a low Earth orbit to study mesospheric wave structures over a wide range of horizontal scales in the altitude range 80 - 100 km. The instrument has six wavelength channels which consist of 4 channels of IR and 2 of UV. We are proposing an optical design based on three mirror aplanatic off-axis reflective system. The entrance pupil diameter and effective focal length are 45 mm and 270 mm, respectively. The FOV is $5.5^{\circ}{\times}1^{\circ}$ and the secondary mirror is set for stop. The optical specification is required to have an encircled energy of at least 80 % within a diameter of 21 um. We performed sensitivity analysis for the longest wavelength of 772 nm in consideration of the diffraction limit of system. The results show that tolerance limits for positions and angles of the mirrors are not very sensitive compared with typical error budgets of manufacturing and assembling process. The secondary mirror has the most sensitive tolerance for surface figure of 250 nm in root-mean-square.
