Factors associated with financial support in old age for young and middle-aged rural residents in China

This study examined the factors associated with financial support in old age from three primary mechanisms-personal savings,family support,and social insurance-to explore the implications for the future development of China's rural social welfare system.Cross-sectional surveys of 1392 young and middle-aged rural residents were conducted in July and August2012.The results showed that while social insurance was increasingly acceptable,personal savings and family support still had fundamental value.Combining the three mechanisms,the rural old-age welfare system presented nontraditional features.China's new rural endowment insurance is discussed as a means to address the need for financial support among the rural aging population.

From the Voices in the Narratives of After-School Support Advisors: Support for Children’s After-School Support Advisors in Japan

This paper examines how advisors perceive the voices made by Mr.A(pseudonym),the founder of after-school support for children(Initiative Z:pseudonym)in Japan,to advisors who support children.Furthermore,the purpose of this study is to find out how advisors think about the voices and that the voices have led or not advisors to support children,if to do so,what points are key to continuing support for children.Therefore,in Initiative Z,I conducted a survey of two advisors who were approached by Mr.A,who is involved in supporting children as an advisor.As a result of analyzing the narratives obtained from interviews with the two advisors,it was found that the advisor had a sense of being recognized by Mr.A because Mr.A acknowledged the advisor’s way of life.This feeling on the part of the advisor led to trust in Mr.A,and the advisor was in tune with Mr.A’s thoughts on after-school support,suggesting that the advisor was providing support to the child.

Communication Skills Training for Residents: Which Variables Predict Learning of Skills?

Objective: This study aimed to determine variables associated (predictors and correlates) with the learning of assessment and supportive skills in the context of a communication skills training for medical residents. Methods: Learning was measured by comparing residents’ communication skills in a simulated consultation before and after a communication skills training. Communication skills were transcribed and tagged with a computer-assisted program. Potential variables associated with learning (residents’ characteristics, contextual characteristics and pre-training communication skills) were measured before the training and entered in regression analysis. Results: Fifty-six residents followed the training between 2002 and 2006. Poor pre-training assessment and supportive skills predicted the respective learning of these skills. Better assessment skills’ learning was predicted by copings (i.e. lower level of emotional coping), lower levels of self-efficacy and depersonalization. Better supportive skills’ learning was predicted by a lower work experience and associated with a higher training attendance rate. Conclusions: Predictors and correlates of assessment and supportive skills learning were different. Trainers needed to detect certain residents’ characteristics (i.e. depersonalization) in order to optimize assessment skills learning. Trainers needed to be aware that supportive skills are difficult to learn and to teach and may need more training hours.

Teaching Ultrasound Imaging for Central Line Placement—A Resident’s Perspective

The availability of ultrasound (US) devices has refined techniques for vascular access. The resident trainee’s ability to learn US techniques depends upon device availability, skills, and motivation of instructors. We hypothesized that hands-on teaching program of US techniques for vascular access would have a positive impact on the trainee’s perceptions. After IRB approval, PGY3 anesthesiology residents with limited prior experience in US-guided vascular access underwent close supervision by attending staff as they performed US-guided Internal Jugular Vein (IJV) central line placements. A total of 66 land mark (LM) and 75 US-guided IJV cannulation performed by 19 residents were supervised. Residents completing the study were more proactive with 68.4% agreeing to use US based techniques for an anticipated difficulty in accessing central lines. The graduating residents involved in the study all strongly agreed that US imaging for vascular access was within the scope of practice of all anesthesiologists, and that training guidelines be established and incorporated in their practice. Fifty eight percent of residents stated that their confidence and skill levels had significantly improved. Teaching US-guided techniques resulted in an increase employment of such techniques by graduating residents with no impediment attributed to knowledge deficits or inexperience. Residents were more proactive with using US for anticipated difficulty in IJV placement. A short neck, poor landmark, anticoagulation, morbid obesity favored US use by residents. Systematic teaching of US techniques is justified as it significantly improves the resident’s perceptions and confidence.

基于ISVM-DS的红外多传感器融合识别方法

弹道中段目标为一个目标群,包括弹头、诱饵、碎片等,并且由于距离传感器较远,红外成像为点目标,可用信息较少,因此单一的红外传感器往往难以满足识别要求,需要融合多个传感器进行识别。针对红外多传感器的融合识别问题,本文提出了基于增量支持向量机和D-S(increment support vector machine-Dempster-Shafer,ISVM-DS)证据理论的融合识别方法。首先,训练多个波段传感器红外特征的支持向量数据描述(support vector data description,SVDD)模型,生成壳向量并训练其ISVM模型;接着,采用ISVM模型的后验概率生成基本概率赋值(basic probability assignment,BPA);最后,利用D-S证据理论对多个证据的BPA进行融合,输出分类结果。实验结果表明,该方法能有效提高目标识别的准确性。

Dynamics Modeling and Numerical Analysis of Rotor with Elastic Support/Dry Friction Dampers

The elastic support/dry friction damper is a type of damper which is used for active vibration control in a rotor system.To establish the analytical model of this type of damper,a two-dimensional friction model-ball/plate model was proposed.By using this ball/plate model,a dynamics model of rotor with elastic support/dry friction dampers was established and experimentally verified.Moreover,the damping performance of the elastic support/dry friction damper was studied numerically with respect to some variable parameters.The numerical study shows that the damping performance of the elastic support/dry friction damper is closely related to the stiffness distribution of the rotor-support system,the damper location,the pressing force between the moving and stationary disk,the friction coefficient,the tangential contact stiffness of the contact interface,and the stiffness of the stationary disk.In general,the damper should be located on an elastic support which has a large vibration amplitude in order to achieve a better damping performance,and the more vibration energy in this elastic support concentrates,the better performance of the damper will be.The larger the tangential contact stiffness of the contact interface,and the stiffness of the stationary disk are,the better performance of the damper will be.There will be an optimal value of the friction force at which the damper performs best.

Planning a Patient-Centered Parkinson’s Disease Support Program: Insights from Narrative Medicine

Background: We desired relevant information from patients with Parkinson’s disease (PD) and their caregivers for help in planning a long-term support program. Methods: We compared 3 ap-proaches: 1) a standard needs assessment questionnaire, the Camberwell assessment of need in the elderly, 2) an open-ended listing of needs, and 3) participation in a narrative medicine program in which health care professionals were involved. Results: On the questionnaire, patients reported physical needs as the most important while their caregivers were more concerned about psychological needs. The open-ended listings revealed additional needs, particularly access to re-liable information about PD and to opportunities to participate in clinical research. The narrative medicine process yielded a number of new insights and proposed solutions, particularly related to the heterogeneity of needs across individuals, the importance of providing hope, and the fact that caregivers expressed that their needs had been largely neglected. Participation in the narrative medicine sessions led to an increase in measured empathy by health care professionals, an im-provement in measured depression among PD patients, but a worsening of measured depression among the caregivers. Conclusions: We have identified important needs and potential solutions to be considered in providing long-term support to patients with PD and their caregivers.

Speech Analysis for Diagnosis of Parkinson’s Disease Using Genetic Algorithm and Support Vector Machine

Parkinson’s disease (PD) is the most common disease of motor system degeneration that occurs when the dopamine-producing cells are damaged in substantia nigra. To detect PD, various signals have been investigated, including EEG, gait and speech. Since approximately 90 percent of the people with PD suffer from speech disorders, speech analysis is considered as the most common technique for this aim. This paper proposes a new algorithm for diagnosing of Parkinson’s disease based on voice analysis. In the first step, genetic algorithm (GA) is undertaken for selecting optimized features from all extracted features. Afterwards a network based on support vector machine (SVM) is used for classification between healthy and people with Parkinson. The dataset of this research is composed of a range of biomedical voice signals from 31 people, 23 with Parkinson’s disease and 8 healthy people. The subjects were asked to pronounce letter “A” for 3 seconds. 22 linear and non-linear features were extracted from the signals that 14 features were based on F0 (fundamental frequency or pitch), jitter, shimmer and noise to harmonics ratio, which are main factors in voice signal. Because changing in these factors is noticeable for the people with PD, optimized features were selected among them. Of the various numbers of optimized features, the data classification was investigated. Results show that the classification accuracy percent of 94.50 per 4 optimized features, the accuracy percent of 93.66 per 7 optimized features and the accuracy percent of 94.22 per 9 optimized features, could be achieved. It can be observed that the best classification accuracy may be achieved using Fhi (Hz), Fho (Hz), jitter (RAP) and shimmer (APQ5).

The Mixture Japanese and Western Style in the Image of theGovernor-General’s Residence of Taiwan Under Japanese Rule 1

This paper focused on Japan who was as a new colonial government in Taiwan under Japanese rule,during the period of which took official buildings or urban planning mainly of a series of Western European-style architecture as a ruler’s cultural identity and a modern Taiwan policy.However,in the context of East Asian modernity,the basic colonial not only mixed Eurocentric,but also included Japan Center and the interaction between the two.Therefore,the scope of research and discussion shall have regarded to the non-Western,non-white nature of the Japanese Empire,and its colonial/modernity construction is another new model.Taiwan Governor-General’s Residence as the Governor-General’s residence for Japanese government combined administrative office,daily living,and social life,showing a symbol of Japan’s colonial ruling class,and a hostel to greet Japanese royal family and the nobility from time to time.As a mansion of both Western Baroque and Japanese style,its architectural design has class meaning,therefore it featured with a class-separation building,also combined the leisure of Western high society.The associated festivals at that time included tea party,fairs and royal family welcoming pilgrimage,the part of which with a strong political implication.This paper mainly uses the images of the Taiwan Governor-General’s Residence during the Japanese rule period and the literature at that time to restore the mixed taste and Japanese-Western style of Taiwan at that time.The Japanese colonists ruled the complex interactions of different ethnic groups in Taiwan.
