    Abstract: To increase the productivity of injection molding machines, we developed a smart injection part weight stability control system based on C++ programming and domain knowledge. The proposed system is meant to eliminate variability in the quality of injected parts by adjusting the changeover position. We developed a viscosity index based on melt pressure data related to guide the adjustment to the changeover position in accordance with material properties. This was achieved by mounting a pressure sensor on the nozzle of the injection molding machine to enable the on-line monitoring of pressure throughout the injection molding process. A series of experiments was conducted to characterize the relationship between viscosity index and injection-molded samples in order to validate the efficacy of the proposed injection stability system. Single-factor experiments were conducted with the changeover position and melt temperature as parameters. The quality of the molded samples obtained under different process parameters was evaluated in terms of weight. Experiment results revealed a correlation between changes in viscosity index and changes in the weight of the samples. The injection stability system can also be operated in self-adjusting mode, in which the changeover position is varied according to viscosity index. In experiments, abnormal machine operations prompted the adjustment of changeover position. Variation in the weight of parts was used to define an index to validate the efficacy of the proposed system.

    Abstract: To investigate the associations between unawareness of deficits and clinical correlates, including apathy and depression, among patients with dementia due to Alzheimer’s disease (AD). Methods: Fifty-five patients with AD were enrolled. Unawareness of memory deficits and psychosis or behavior problems was assessed. The Apathy Evaluation Scale informant version and the Cornell Scale for Depression in Dementia (CSDD) were used to measure apathy and depression, respectively. Results: In all, 32 (57.2%) and 27 (49.1%) participants were identified as being unaware of memory deficits and psychosis or behavior problems, respectively. Unawareness of memory deficits was associated with lower scores on the Mini-Mental State Examination (MMSE) and higher scores on the CSDD. Unawareness of psychosis or behavior problems was associated with lower scores on the MMSE. Conclusion: Unawareness of deficits among patients with AD was common. The 2 domains of unawareness showed different characteristics and may possibly present different etiologies.

    Abstract: Systemic lupus erythematosus (SLE) is a female-dominated autoimmune disease that can occur at any age and has a diverse course. The clinical manifestation of this disease can vary depending on the patient’s age at onset. The aim of this study was to characterise the comorbidities at the time of SLE diagnosis and after in different age groups. Methods A total 1042 incident cases of SLE with a Catastrophic Illness Card in 2005 and 10,420 age- and sex-matched controls from the general population registered in the National Health Insurance Research Database in Taiwan were enrolled in the study. The risk of comorbidities before (adjusted odds ratio, [aOR]) and after (adjusted hazard ratio, [aHR] ) of SLE was analysed. The burden of these SLE-associated comorbidities was weight by the Charlson comorbidity index (CCI). We used the cumulative incidence to evaluate the impact of comorbidities on different age onset groups. Results In this study, musculoskeletal diseases had the highest positive association (aOR, 5.29; 95% confidence interval [CI]: 4.25–6.57) prior to the diagnosis of SLE and they were also the most common developing incident comorbidity after the diagnosis (HR, 13.7; 95% CI: 11.91–15.77). It only took less than 1 year for 50% of the late-onset SLE patients to develop any increase in CCI score. The developing comorbidities attributed to 16.3% all-cause mortality and they had the greatest impact on late-onset SLE patients, with 33.3% cumulative incidence to all-cause mortality. There is no difference in the incidence of infectious diseases across different age groups. The herpes zoster infection had the greatest cumulative incidence among the category of infection diseases in child-onset SLE patients. Conclusion SLE patients had increased risks of multiple pre-existing comorbidities at diagnosis. The developed comorbidity after diagnosis could contribute to all-cause mortality. The herpes zoster infection is primarily an issue in child-onset SLE patients.

    Abstract: This study aims to examine whether coping strategies employed by caregivers are related to distinct symptoms of patients with dementia and to investigate the associations between burden and coping among caregivers of patients with dementia. Methods: A cross-sectional study design was used. A total of 57 caregivers of patients with dementia were enrolled. Coping strategies were assessed using the Ways of Coping Checklist, and burden was assessed using the Chinese version of Caregiver Burden Inventory. Correlations between coping and patients’ behavior or memory problems were examined. Severities of behavior and memory problems were adjusted to examine the correlations between caregiver burden and coping strategies. Results: The patients’ disruptive behavior problems were associated with avoidance, and depression problems were associated with avoidance and wishful thinking. After adjusting for severity of behavior problems, coping strategies using avoidance were positively correlated with caregiver burden. Conclusions: Emotion-focused coping strategies are a marker of caregiver burden.

    Abstract: Application of combining herbal medicine and biomedical material science to nerve regeneration is a new approach. In this study, we describe a novel use of purified genipin, which can be extracted from Gardenia jasminoides Ellis, fixing the gelatin to be an extracellular matrix for peripheral nerve regeneration. A 10-mm gap of rat sciatic nerve was created between the proximal and distal nerve stumps, which were sutured into silicone rubber tubes filled with either the genipin-fixed gelatin or collagen gel. Silicone rubber tubes filled with saline were used as controls. Six weeks after implantation, regeneration across the nerve gaps occurred in 80 and 90% of the animals from the groups of genipin-fixed gelatin and collagen, respectively, whereas only 30% in the control group. Large numbers of myelinated axons were also seen in the genipin-fixed gelatin (5104±3278) and the collagen groups (8063±1807). These findings indicated that the genipin-fixed gelatin could be an acceptable extracellular matrix for nerve regeneration.

    Abstract: Background. The timing of electrical stimulation (ES) after peripheral nerve transection may enhance axonal regeneration and functional recovery. Objective. The authors examined whether percutaneous ES at 1 mA and 2 Hz affects regeneration between the proximal and distal nerve stumps. Methods. Four groups of adult rats were subjected to sciatic nerve section followed by repair using silicone rubber conduits across a 10-mm gap. All groups received ES for 15 minutes every other day for 2 weeks. Stimulation was initiated on day 1 following the nerve repair for group A, day 8 for group B, and day 15 for group C. The control group D received no ES. Results. At 6 weeks after surgery in groups B and C, histological evaluations showed a significantly higher number of regenerated myelinated fibers in the sciatic nerve, and the electrophysiological results showed higher levels of reinnervation with relatively larger mean values of amplitudes, durations, and areas of compound muscle action potentials compared with A and D. Conclusion. A short delay in the onset of ES may improve the recovery of a severe peripheral nerve injury, which should be considered as a way of augmenting rehabilitative approaches.

    Abstract: File pollution is a recent security threat to peer-to-peer (P2P) file sharing systems. By disseminating numerous polluted files with mismatched or partially tampered contents in the P2P system, the attacker causes users to download unexpected files. This attack is aimed at frustrating users and making them abandon the system. Present researches on combating file pollution have mostly focused on pollution modeling or evaluating the extent of pollution. Only a few researches have proposed effective methods to eliminate pollution attacks, and they are primarily based on reputation systems and blacklisting mechanisms. However, these methods require exchange of significant feedback among the peers in order to identify the malicious peers or polluted files in the system. In this paper, we describe the application of fault-tolerant mechanism used in the redundant arrays of independent disks system to suppress file pollution attacks based on the concept that P2P file sharing systems currently have global file storage systems. We have extended the previously developed Fluid Model to analyze and evaluate the proposed antipollution mechanism. The model accuracy has been demonstrated by performing several simulation experiments; the proposed mechanism could effectively suppress the pollution and successfully decrease the polluted-time exposure of a P2P file sharing system by approximately 40∼60%.

    Abstract: This study aimed to investigate the associations among dementia, psychotropic medications and the risk of overall injuries. In this nationwide matched cohort study, a total of 144 008 enrolled patients ≥age of 50, with 36 002 study subjects who suffered from dementia and 108 006 controls matched for sex and age, from the Inpatient Dataset, for the period 2000–2010 in Taiwan were selected from the National Health Insurance Research Database, according to International Classification of Diseases, 9th Revision, Clinical Modification. When adjusting for the confounding factors, a Cox proportional hazards analysis was used to compare the risk of developing psychiatric disorders during the 10 years of follow-up. Of the study subjects, 6701 (18.61%) suffered injury when compared with 20 919 (19.37%) in the control group. The Cox regression analysis revealed that the study subjects were more likely to develop an injury (HR: 2.294, 95% CI=2.229 to 2.361, P 〈 0.001) after adjusting for sex, age, monthly income, urbanization level, geographic region, and comorbidities. Psychotropic medications in the subjects with dementia were associated with the risk of injury (adjusted HR=0.217, 95% CI: 0.206 to 0.228, P 〈 0.001). Cognitive enhancers, including acetylcholinesterase inhibitors and memantine, were associated with the risk of injury in the study subjects after being adjusted for all comorbidities and medications (adjusted HR=0.712(95% CI=0.512 to 0.925, P 〈 0.01)). In conclusion, patients who suffered dementia had a higher risk of developing injury, and the cognitive enhancers were associated with the decreased risk of injury.

    Abstract: This study aims to investigate the association between pulmonary embolism (PE) and the risk of psychiatric disorders. A total of 21,916 patients aged ≥20 years with PE between January 1, 2000, and December 31, 2015, were selected from the National Health Insurance Research Database of Taiwan, along with 65,748 (1:3) controls matched for sex and age. Cox regression model revealed the crude HR was 1.539 (95% CI 1.481 to 1.599; p 〈 0.001), and after adjusting all the covariates, the adjusted HR was 1.704 (95% CI 1.435 to 1.991, p 〈 0.001), for the risk of psychiatric disorders in the PE cohort. PE was associated with the overall psychiatric disorders, dementia, anxiety, depression, and sleep disorders, after the exclusion of the psychiatric diagnoses in the first year. PE was associated with the overall psychiatric disorders, dementia, anxiety, and depression, after the exclusion of the psychiatric diagnoses in the first 5 years. The patients with PE were associated with psychiatric disorders. This finding could serve as a reminder to the physicians to be more watchful and aware in the long-term follow-up of patients with PE for their care and potential mental health problems.
