Motion/Posture Modeling and Simulation Verification of Physically Handicapped in Manufacturing System Design

Non-obstacle design is critical to tailor physically handicapped workers in manufacturing system. Simultaneous consideration of variability in physically disabled users, machines and environment of the manufacturing system is extremely complex and generally requires modeling of physically handicapped interaction with the system. Most current modeling either concentrates on the task results or functional disability. The integration of physical constraints with task constraints is far more complex because of functional disability and its extended influence on adjacent body parts. A framework is proposed to integrate the two constraints and thus model the specific behavior of the physical handicapped in virtual environment generated by product specifications. Within the framework a simplified model of physical disabled body is constructed, and body motion is generated based on 3 levels of constraints（effecter constraints, kinematics constraints and physical constraints）. The kinematics and dynamic calculations are made and optimized based on the weighting manipulated by the kinematics constraints and dynamic constraints. With object transferring task as example, the model is validated in Jack 6.0. Modelled task motion elements except for squatting and overreaching well matched with captured motion elements. The proposed modeling method can model the complex behavior of the physically handicapped by integrating both task and physical disability constraints.

Enhanced Surveillance for National (Handicapped) Sports Games in Wakayama, Japan 2015

Introduction: We undertook enhanced surveillance of the 2015 Kinokuni Wakayama National Sports Games (70th National Sports Games) and the Kinokuni Wakayama Handicapped Sports Games (15th National Handicapped Sports Games) held in Wakayama prefecture in 2015, for which this paper presented operational details and an evaluation. Methods: Enhanced surveillance conducted involved (Nursery) School Absenteeism Surveillance system ((N)SASSy), Prescription Surveillance, and Ambulance Transfer Surveillance from 30 August through 9 November. We evaluated those surveillances on all days including weekends, integrated the results as a daily report, and published it on the web. Results: We found no cluster or cases requiring more tracing and investigation except for suspected cases of rubella in (N)SASSy. Moreover, no moderate aberration was found for two consecutive days for the same area and symptom. Conclusion: Our experience with this enhanced surveillance presents important lessons for countermeasures by local governments for mass gatherings or politically important events.

Handicapped or Disabled? a Predictable Shift in Legal Terminology

The negative impact of the term canji ren("handicapped person")has gradually come to be recognized.The terms canzhang ren("person with disabilities")and canji ren("handicapped person")have been used interchangeably in academia.However,such interchangeable use causes difficulties for both law enforcement and the judiciary,and also gives rise to public confusion.Based on the etymology of"disabled",its Chinese translation,and a survey of the three models of the concept of"disability",it is apparent that the Convention on the Rights of Persons with Disabilities adopts an"integrated definition"of disability.Law of the People’s Republic of China on the Protection of Disabled Persons defines handicapped person in much the same way as the Convention on the Rights of Persons with Disabilities,with only minor deviations.Hence,to replace the term handicapped person with persons with disabilities is both in line with relevant provisions of the Convention as well as the legislative intent of China’s"Law on the Protection of Disabled Persons".In addition,this benefits the elimination of social discrimination and prejudice,as well as expanding the scope of legal protection.

From “Handicapped” to “Physically Challenged”: the Discourse Transformation in China's Cause of the Physically Challenged in the New Era

In the human rights discourse of China, the terminology used for canfei(handicapped) was changed to canji(persons with disabilities) and then canzhang(physically challenged), which has literally manifested the unfolding of the new philosophy for the physically challenged. In particular, the achievements of the China physically-challenged programs in the new era shows that at both institutional and mindset dimensions, it has stepped beyond the definition of canji and entered into the higher level featured by the term canzhang. As for the future practical strategies of the national physically-challenged programs, it is important to hold on the ideas of socialist humanism, and to explore the constitutional model and human rights model for physically-challenged rights protection. This is also the major clue to conclude the achievements of the two "30 years" physically-challenged programs since the establishment of the PRC. Countries worldwide, particularly developing countries, can draw experience from this China model of developing the programs and strategies of human rights-based governance. The Chinese experience and theories also can be shared by community with a shared future for human beings.

Love Makes Their Life Worth——Story about Shao Junke's help for the handicapped

The handicapped, a special group in society, usually encounter many difficulties in employment, marriage, and daily life.Some difficulties are what they cannot conquer by themselves. It is also not easy for them to integrate into society. However, if there is a person who helps the hand- icapped find a job, build up confidence and make their life worth; if there is a person who helps them set up their families and incorporate in a harmonious community;

Better Guarantee for Handicapped

The Chinese government attaches much importance to the protection of the rights and interests of the handicapped people. In 2001, it started to implement the Outlined Program for the Development of the Handicapped for 2001-2005. With the protection of the basic living and strengthening the grassroots handicapped people as the emphasis, the program sets the tasks and targets and main measures for the cause of the handicapped people during the tenth five-year plan period. In the meanwhile, the state has strengthened legal protection of the rights and interests of the handi-

Life of Old,Sick and Handicapped Prisoners in China

At the foot of the Great Wall northwest of Beijing, there is a special prison, called Yanqing Prison. It is special, because it gathers all theimprisoned old, sick and handicapped offenders in the Beijing area for the purpose of facilitating management.

Protect Rights and Interests of the Handicapped

Yuncheng is a city in the southwestern part of North China＇s Shanxi Province. It has a handicapped population of 223,000 or 4.5% of the total population of 4.985 million. The city has made big progress in protecting the rights and interests of handicapped people since the handicapped associations were set up at the city and county levels.

Implementation outcomes of a sensory integration therapy program with computerized dynamic posturography in patients with balance and sensory dysfunction

Objective:We describe the first-year implementation experience of an Instrumented Sensory Integration Therapy Program in Audiological&Balance Center patients.Design:This is a retrospective descriptive study.Participants included Seventy-three adults with diagnoses of acute,episodic,or chronic vestibular syndromes.They were classified into the following two groups:group 1 included 46 individuals treated with ISIT plus VRT,and group 2 included 27 individuals treated only with ISIT.Results:The Sensory Organization Test(SOT)for both groups showed a statistical significance for all three sensory inputs;visual systems(G1:p=0.0003;G2:p=0.0337),vestibular system(G1:p<0.0001;G2:p=0.0003),and balance as demonstrated by compound balance score(G1:p<0.0001;G2:p=0.0035),and balance percentage deficit(G1:p<0.0001;G2:p=0.0078).Conclusions:The severity and complexity of functional neurological disorders in the context of vestibular syndromes seem to require between 10 and 20 therapy sessions,and combined ISIT plus VRT appears to be more effective than ISIT as a monotherapy.

突发性聋伴耳鸣患者治疗前后耳鸣残疾量表和视觉模拟量表比较及相关性

突发性聋伴耳鸣的发病率较高，多数耳呜患者可伴情绪紧张和疲劳，这成为众多临床医师工作中需要解决的问题。耳呜作为一种主观感受，缺乏客观有效的检测手段。国外应用于评价耳呜的最常用量表主要有耳鸣残疾量表（tinnitus handicap inventory，THI）和视觉模拟量表（visual-analoguescale，VAS）。

Implementation of a Biometric Interface in Voice Controlled Wheelchairs

In order to assist physically handicapped persons in their movements,we developed an embedded isolated word speech recognition system(ASR)applied to voice control of smart wheelchairs.However,in spite of the existence in the industrial market of several kinds of electric wheelchairs,the problem remains the need to manually control this device by hand via joystick;which limits their use especially by people with severe disabilities.Thus,a significant number of disabled people cannot use a standard electric wheelchair or drive it with difficulty.The proposed solution is to use the voice to control and drive the wheelchair instead of classical joysticks.The intelligent chair is equipped with an obstacle detection system consisting of ultrasonic sensors,a moving navigation algorithm and a speech acquisition and recognition module for voice control embedded in a DSP card.The ASR architecture consists of two main modules.The first one is the speech parameterization module(features extraction)and the second module is the classifier which identifies the speech and generates the control word to motors power unit.The training and recognition phases are based on Hidden Markov Models(HMM),K-means,Baum-Welch and Viterbi algorithms.The database consists of 39 isolated speaker words(13 words pronounced 3 times under different environments and conditions).The simulations are tested under Matlab environment and the real-time implementation is performed by C language with code composer studio embedded in a TMS 320 C6416 DSP kit.The results and experiments obtained gave promising recognition ratio and accuracy around 99%in clean environment.However,the system accuracy decreases considerably in noisy environments,especially for SNR values below 5 dB(in street:78%,in factory:52%).

Angioplasty and stenting for severe vertebral artery orifice stenosis: effects on cerebellar function remodeling verified by blood oxygen level-dependent functional magnetic resonance imaging

Vertebral artery orifice stenting may improve blood supply of the posterior circulation of the brain to regions such as the cerebellum and brainstem. However, previous studies have mainly focused on recovery of cerebral blood flow and perfusion in the posterior circulation after interventional therapy. This study examined the effects of functional recovery of local brain tissue on cerebellar function remodeling using blood oxygen level-dependent functional magnetic reso- nance imaging before and after interventional therapy. A total of 40 Chinese patients with severe unilateral vertebral artery orifice stenosis were enrolled in this study. Patients were equally and randomly assigned to intervention and control groups. The control group received drug treat- ment only. The intervention group received vertebral artery orifice angioplasty and stenting ＋ identical drug treatment to the control group. At 13 days after treatment, the Dizziness Handicap Inventory score was compared between the intervention and control groups. Cerebellar function remodeling was observed between the two groups using blood oxygen level-dependent functional magnetic resonance imaging. The improvement in dizziness handicap and cerebellar function was more obvious in the intervention group than in the control group. Interventional therapy for severe vertebral artery orifice stenosis may effectively promote cerebellar function remodeling and exert neuroprotective effects.

Cognitive disorder and changes in cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor following brain injury

BACKGROUND： Learning and memory damage is one of the most permanent and the severest symptoms of traumatic brain injury; it can seriously influence the normal life and work of patients. Some research has demonstrated that cognitive disorder is closely related to nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor. OBJECTIVE： To summarize the cognitive disorder and changes in nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor following brain injury. RETRIEVAL STRATEGY： A computer-based online search was conducted in PUBMED for English language publications containing the key words ＂brain injured, cognitive handicap, acetylcholine, N-methyl-D aspartate receptors, neural cell adhesion molecule, brain-derived neurotrophic factor＂ from January 2000 to December 2007. There were 44 papers in total. Inclusion criteria： ① articles about changes in nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor following brain injury; ② articles in the same researching circle published in authoritative journals or recently published. Exclusion criteria： duplicated articles. LITERATURE EVALUATION： References were mainly derived from research on changes in these four factors following brain injury. The 20 included papers were clinical or basic experimental studies. DATA SYNTHESIS： After craniocerebral injury, changes in these four factors in brain were similar to those during recovery from cognitive disorder, to a certain degree. Some data have indicated that activation of nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor could greatly improve cognitive disorder following brain injury. However, there are still a lot of questions remaining; for example, how do these factors change at different time points after brain injury, and what is the relationship between associated factors and cognitive disorder. CONCLUSION： It is necessary to comprehensively study some associated factors, to analyze their changes and their relationship with cognitive disorder following brain injury, and to investigate their effects at different time points after brain injury.

Tinnitus characteristics and associated variables on Tinnitus Handicap Inventory among a Hungarian population

Background:Tinnitus is a sound precepted without an external sound stimulus.Its background can be categorised into primary and secondary cases.The secondary cases include pathologies of the external,middle and inner ear.Tinnitus can be objective or subjective;the latter can only identified by the sufferer.Previous research results have shown that tinnitus significantly affects the quality of life and daily functioning.Objectives:To analyse the impact of tinnitus on the daily functioning and the possible influence of demographical data and tinnitus duration on it.Methods:630 patients(265 males and 365 females,25e85 years of age)suffering from primary tinnitus were enrolled.In the Hungarian language,these patients completed the Tinnitus Handicap Inventory(THI)questionnaire and underwent a complete otorhinolaryngological examination.IBM SPSS V24 software was used for data processing;correlation tests,the Mann-Whitney U and Kruskal-Wallis nonparametric tests were used.Results:According to the THI questionnaires outcomes,most patients(62.5%)were presented with a mild handicap.Based on statistical analysis,no significant correlation was observed between the total THI points and the age of the patients,along with the duration and localisation of the symptoms.However,the total THI scores of male and female patients significantly differed,indicating higher THI values in the female group(p=0.00052*).Conclusions:The tinnitus severity was not affected by the duration,localisation of the symptoms and age but by gender,indicating higher values in the case of females.

An Analysis of the Global and Partial Voice Handicap Index in Patients with Early Glottic Carcinoma Treated with High Level of Irradiation

Background: This is a retrospective study on a group of patients with early glottic carcinoma, treated with curative radiotherapy. The aim of the study is to assess voice quality after treatment. We also evaluated local recurrence, overall survival, disease free survival and toxicity. Material and Methods: We examined a total of 36 patients, out of which 27 were smokers: 10 females/5 smokers;26 males/22 smokers. The sample was observed from January 2007 to July 2012 (average follow-up period: 33.5 months, range 12 - 76). Diagnosis of early glottic carcinoma was eight during the two-year period 2007/2008, nine during 2009/2010, eleven during year 2011 and eight during year 2012. All patients suffering from early glottic carcinoma, histopathologically confirmed, were classified as follows: 24 patients T1a, 3 patients T1b, 6 patients T2 and 3 patients had a carcinoma in situ. They were treated only with conventional radiotherapy. After the treatment (total dose 70 Gy), patients were asked to fill out the Voice Handicap Index (VHI) questionnaire, composed of 30 questions that covered physical, emotional and functional areas. Results: The global VHI was evidenced with good voice quality (62% of patients: VHI < 30;34% of patients: VHI 31 - 60). Vocal disability was mild in over 70% of patients within the physical area and over 80% within the emotional area. We observed two local recurrences, one occurred five years after the end of radiation therapy and one six months after. In terms of toxicity, we observed that acute reactions, such as dysphonia, dysphagia and erythema, were relatively limited. Conclusions: The VHI index suggests that radiotherapy produces acceptable functional results, with limited repercussion on life quality. In line with literature, our data confirmed good cure rates and larynx preservation (94.4%).

A Preliminary Receiver Operating Characteristic Analysis on Voice Handicap Index Results of the Greek Voice-Disordered Patients

Objective(s): The cutting-edge assessment of voice disorders includes objective and subjective methods in the daily clinical practice. The latter assessment is usually performed through the administration of self-reported questionnaires. Voice Handicap Index (VHI) is one of the most widely used tools both in clinical practice and in research level. This tool-questionnaire was employed in this research along with the Voice Evaluation Template (VEF). In turn, the aim of this study was to analyse and produce the cut-off points of VHI for voice-disordered patients in Greece by using Receiver Operating Characteristic Curves (ROC Curves). Methods: Sixty-three participants (40 non-dysphonic and 23 with different types of dysphonia) were classified by ENT (Ear, Nose, and Throat) doctors and SLPs (Speech-Language Pathologists). The Hellenic VHI along with the translated Greek version of the VEF was administered to the subjects of this research. Results: The voice-disordered subjects exhibited higher overall VHI scores (in total and in its 3 subdomains) compared to the control group. Statistical significant differences were found between dysphonic and non-dysphonic participants for all VHI’s construct domains. The cut-off point of VHI total score was estimated at the value of 14.50 (sensitivity: 0.870, 1-specificity: 0.000). Moreover, the cut-off points of the three subdomains were computed as 7.50 for functional (sensitivity: 0.783, 1-specificity: 0.000), 8.50 for physical (sensitivity: 0.739, 1-specificity: 0.000) and 8.50 for emotional domain (sensitivity: 0.783, 1-specificity: 0.050). Conclusion: The preliminary statistical and ROC data analysis of VHI concluded that by using this type of assessment method, populations with or without voice disorders (in Greece) can be distinguished. Albeit this tool is a non-interventional method it could consequently offer an adequate screening and monitoring capability.

Preliminary Receiver Operating Characteristic Analysis on Voice Handicap Index of Laryngeal Inflammation in Greek Patients

Objective(s): Laryngeal inflammations lead to voice disorders. Medical conditions such as chronic laryngitis, gastroesophageal reflux, laryngopharyngeal reflux, Reinke edema and/or vocal folds hemorrhage, result in diverse symptoms including chronic cough, throat cleaning and dysphonia (e.g. hoarseness). In turn, the dysphonic symptoms can be evaluated via subjective and objective procedures. The objective procedures usually include self-perceived questionnaires like the Voice Handicap Index (VHI). Studies reported that VHI can distinguish objectively dysphonic and non-dysphonic populations using the cut-off points of Receiver Operating Characteristic Curves. The purpose of this study was to calculate the cut-off points for individuals exhibiting voice symptoms which had been developed from laryngeal inflammatory diseases in Greece. Methods: One hundred and twelve participants (90 non-dysphonic and 22 dysphonic) filled in the Hellenic Voice Handicap Index (VHI) and the Greek translated version of Voice Evaluation Template (VEF) were administrated. All subjects were evaluated by an Otolaryngologist and a Speech-Language Pathologist. Results: The group with voice disorders exhibited higher VHI scores (in total and in its 3 subdomains) compared to non-dysphonic subgroup. Statistical significant differences were found for all VHI’s total cut-off point of 19.50 (sensitivity: 0.882, 1-specificity: 0.011) and for its three subdomains [functional 6.50 (sensitivity = 0.636, and 1-specificity = 0.022);physical 9.50 (sensitivity = 0.636, and 1-specificity = 0.000);emotional 6.50 (sensitivity = 0.455, and 1-specificity = 0.133)]. Conclusion: The preliminary results showed that VHI could discriminate individuals having voice disorders from laryngeal inflammations. The Voice Handicap Index can be used as a primary health care tool and a self-monitoring procedure in acute and sub-acute phases of the laryngeal inflammation.

Column sufficient tensors and tensor complementarity problems

Stimulated by the study of sufficient matrices in linear complementarity problems, we study column sufficient tensors and tensor complementarity problems. Column sufficient tensors constitute a wide range of tensors that include positive semi-definite tensors as special cases. The inheritance property and invariant property of column sufficient tensors are presented. Then, various spectral properties of symmetric column sufficient tensors are given. It is proved that all H-eigenvalues of an even-order symmetric column sufficient tensor are nonnegative, and all its Z-eigenvalues are nonnegative even in the odd order case. After that, a new subclass of column sufficient tensors and the handicap of tensors are defined. We prove that a tensor belongs to the subclass if and only if its handicap is a finite number. Moreover, several optimization models that are equivalent with the handicap of tensors are presented. Finally, as an application of column sufficient tensors, several results on tensor complementarity problems are established.
