Study on Planning Model of Chinese Aged Community in Background of European and American Old-age System

Attention to the pension work is the performance of social development and progress, effective selection of effective old-age way to promote the elderly in his later years and it is the inevitable requirement of the development of the times. On the basis of comparative analysis of the pros and cons of various pension methods, the actual social work department must carry out specific judgment on the specificold people. The elderly need not only the material aspects of life care, but also the need for emotional support and spiritual comfort, in the new historical conditions must be in the body and mind and informed lines and other aspects of the elderly to give loved ones, considerate, warm and friendly , respect and care. This paper proposes the novel perspective on the planning model of Chinese aged community in background of European and American old-age system. In the future, we will apply the proposed model into more scenarios to test the performance.

Retrospective analysis of old-age colitis in the Dutch inflammatory bowel disease population

AIM： To describe the characteristics of Dutch patients with chronic.inflammatory bowel disease （IBD） first diagnosed above 60 years of age-a disease also known as old-age colitis （OAC） and to highlight a condition that has a similar appearance to IBD, namely segmen- tal colitis associated with diverticular disease （SCAD）. METHODS： A retrospective longitudinal survey of patient demographic and clinical characteristics, disease characteristics, diagnostic methods, management and course of disease was performed. The median follow-up period was 10 years. RESULTS： Of a total of 1100 IBD patients attending the Department of Gastroenterology, 59 （50） [median age 82 years （range 64-101）; 25 male （42%）] were identified. These patients were diagnosed with ulcerative colitis （n = 37, 61%）, Crohn＇s disease （n = 14, 24%）, and indeterminate colitis （n = 8, 15%）. Remission was induced in 40 （68%） patients within a median interval of 6 mo （range 1-21） and immunosuppressive therapy was well tolerated. Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis, namely SCAD instead of IBD in five （8%） patients. CONCLUSION： OAC is not an infrequent problem for the gastroenterologist, and should be considered in the evaluation of older patients with clinical features suggestive of IBD. Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD, when diagnosing IBD in the presence of diverticulosis coli.

Study of androgen and atherosclerosis in old-age male

Objective： To observe the difference of androgen and inflammatory cytokines level in atherosclerosis and analyse their relations. Method： Both carotid arteries and arteries of lower extremity were subjected to ultrasonic examination by Doppier＇s method. Those with much atheromatous plaque formation were ranged into case group, and those with normal result formed control group. Total, free testosterone and estradiol were assayed by radioimmunoassay. C reactive protein （CRP） was assayed by nepheloturbidity. Tumor necrosis factor-α（TNF-α）, lnterleukin-6 （IL-6）, lnterleukin-8 （IL-8）, lnterleukin-10 （IL-10）, Interleukin-18 （IL-18）, soluble intercellular adhesion molecule-1 （sICAM-1） and soluble vascular cell adhesion molecule-1 （sVCAM-1） were assayed by ELISA. The mean difference between two groups and the correlation between free testosterone and cytokines were analysed. Results： Free testosterone was （6.337±3.371） pg/L in case group and （11.375±4.733）pg/L in control group, P〈0.01. No differences were found in total testosterone and estradiol. CRP was （27.294±10.238）mg/L in case group and （12.843±6.318） mg/L in control group, P〈0.01. IL-6 was （41.700±31.385）pg/L in case group and （25.396±20.772）pg/L in control group, P〈0.05. IL-8 was （89.249±58.357）pg/L in case group and （67.873±31.227）pg/L in control group, P〈0.05. sICAM-1 was （470.491±134.078）pg/L in case group and （368.487±97.183）pg/L in control group, P〈0.01. sVCAM-1 was （537.808±213.172）pg/L in case group and （457.275±157.273）pg/L in control group, P〈0.05. There were no differences in TNF-α, IL-10 and IL-18. Correlation analysis showed that FT （free testosterone） had negative correlation with CRP, IL-6 and sICAM-1. Among them FT had well correlation with CRP, correlation index was -0.678. Conclusion： Free testosterone was in negative correlation with atherosclerosis in old-age male. Free testosterone may have the role of anti-atherosclerosis, and this effect was not achieved by its transformation to estradiol. Low tree testosterone level was followed by increased level of inflammatory cytokines. Low free testosterones coexist with inflammation and they both affect the process of atherosclerosis in old-age male.

Rural migrants' participation in old-age insurance: a case study of the inter-provincial migrant workers from Sichuan, China

Old-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers' participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants' behavior participating(or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes among migrant workers are drawn from the findings.

一种基于粗糙熵的改进K-modes聚类算法

K-modes聚类算法被广泛应用于人工智能、数据挖掘等领域。传统的K-modes聚类算法有不错的聚类效果,但是存在迭代次数多、计算量大、容易受到冗余属性的干扰等问题,且仅采用简单的0-1匹配的方法来定义2个样本属性值之间的距离,没有充分考虑每个属性对聚类结果的影响。针对上述问题,该文将粗糙熵引入K-modes算法。首先利用粗糙集属性约简算法消除冗余属性,确定各属性的重要程度;然后利用粗糙熵确定每个属性的权重,从而定义新的类内距离。将该文所提算法与传统的K-modes聚类算法分别在4组公开数据集上进行对比试验。试验结果表明,该文所提算法聚类准确率比传统的K-modes聚类算法更高。

Key Elements of “Family” Life Style of Old-age Residential Facilities

The problem of old-age care in China is more and more serious. Under the background of continuous promotion of community old-age, the importance of research on the"family" life style of oldage residential facilities has become increasingly prominent. Through field survey of different types of oldage residential facilities and questionnaire interviews, the shortcomings of the old-age residential facilities in Xi’an were compared and summarized, and the key elements of "family" life style of the old-age residential facilities were concluded, which mainly include urban community embeddedness, family structure elements, indoor furnishings and accompanying care system. The "family" life style of the old-age residential facilities can not only maintain the "kinship" living needs, but also conform to the new direction of promoting the "community" of the old-age residential facilities in China.

Effects of spot size on the operation mode of Ga As photoconductive semiconductor switch employing extrinsic photoconductivity

To guide the illuminating design to improve the on-state performances of gallium arsenide(GaAs)photoconductive semiconductor switch(PCSS),the effect of spot size on the operation mode of GaAsPCSS based on a semi-insulating wafer with a thickness of 1 mm,triggered by a 1064-nm extrinsic laser beam with the rectangular spot,has been investigated experimentally.It is found that the variation of the spot size in length and width can act on the different parts of the output waveform integrating the characteristics of the linear and nonlinear modes,and then significantly boosts the PCSS toward different operation modes.On this basis,a two-channel model containing the active and passive parts is introduced to interpret the relevant influencing mechanisms.Results indicate that the increased spot length can peak the amplitude of static domains in the active part to enhance the development of the nonlinear switching,while the extended spot width can change the distribution of photogenerated carriers on both parts to facilitate the linear switching and weaken the nonlinear switching,which have been proved by comparing the domain evolutions under different spot sizes.

UAV-assisted data collection for wireless sensor networks with dynamic working modes

Wireless Sensor Network(WSN)is a cornerstone of Internet of Things(IoT)and has rich application scenarios.In this work,we consider a heterogeneous WSN whose sensor nodes have a diversity in their Residual Energy(RE).In this work,to protect the sensor nodes with low RE,we investigate dynamic working modes for sensor nodes which are determined by their RE and an introduced energy threshold.Besides,we employ an Unmanned Aerial Vehicle(UAV)to collect the stored data from the heterogeneous WSN.We aim to jointly optimize the cluster head selection,energy threshold and sensor nodes’working mode to minimize the weighted sum of energy con-sumption from the WSN and UAV,subject to the data collection rate constraint.To this end,we propose an efficient search method to search for an optimal energy threshold,and develop a penalty-based successive convex approximation algorithm to select the cluster heads.Then we present a low-complexity iterative approach to solve the joint optimization problem and discuss the implementation procedure.Numerical results justify that our proposed approach is able to reduce the energy consumption of the sensor nodes with low RE significantly and also saves energy for the whole WSN.

Analysis of home care-based multi-level old-age service system

With the deepening of China＇s aging, China＇s social pension problem more obvious each day, and gradually become the focus of attention of the whole society. On the one hand, China entered the aging society, old-age needs to grow exponentially. The sixth national census shows that in our country, the population aged 60 and 13.26% of the total population over the total number of 179 million, 65 years and older the proportion of 8.87% of the total population, the absolute number of nearly 120 million. Hundreds of millions of older age groups will produce a growing demand for care services, which is the original old-age service system and the whole economic and social development is a huge pressure. On the other hand, with the economic and social transformation, the traditional model of family pension has been unable to adapt to the profound changes in modem employment, family structure, the concept of retirement, since most parts of China, ＂old before getting ricE＂ the situation, how to solve the elderly the pension problem is related to the overall situation of China＇s economic and social development, related to the overall situation of building a harmonious society in China. Under current national conditions, the emphasis on the development of a single individual body to meet the growing demand for pension service is not realistic, we must mobilize the enthusiasm of all aspects of the element, multi-service integration of resources subject to their commitment to a different responsibilities and tasks provide a full range of care services according to different types, different levels of the actual needs of the older age groups. On the aging problem is that the whole community to face, you need to multi-government body, families, communities, institutions combine effectively starting from the actual needs of the elderly population, according to the financial assistance, life care, spiritual consolation three set the specific needs of services, through a government-led, home-based care services, community care services for the core and supplementary services for institutions focused on pension and other means to provide a full range of pension services.

Adaptive Trajectory Tracking Control for Nonholonomic Wheeled Mobile Robots:A Barrier Function Sliding Mode Approach

The trajectory tracking control performance of nonholonomic wheeled mobile robots(NWMRs)is subject to nonholonomic constraints,system uncertainties,and external disturbances.This paper proposes a barrier function-based adaptive sliding mode control(BFASMC)method to provide high-precision,fast-response performance and robustness for NWMRs.Compared with the conventional adaptive sliding mode control,the proposed control strategy can guarantee that the sliding mode variables converge to a predefined neighborhood of origin with a predefined reaching time independent of the prior knowledge of the uncertainties and disturbances bounds.Another advantage of the proposed algorithm is that the control gains can be adaptively adjusted to follow the disturbances amplitudes thanks to the barrier function.The benefit is that the overestimation of control gain can be eliminated,resulting in chattering reduction.Moreover,a modified barrier function-like control gain is employed to prevent the input saturation problem due to the physical limit of the actuator.The stability analysis and comparative experiments demonstrate that the proposed BFASMC can ensure the prespecified convergence performance of the NWMR system output variables and strong robustness against uncertainties/disturbances.

Real-Time 4-Mode MDM Transmission Using Commercial 400G OTN Transceivers and All-Fiber Mode Multiplexers

Weakly-coupled mode division multiplexing(MDM)technique is considered a promising candidate to enhance the capacity of an optical transmission system,in which mode multiplexers/demultiplexers(MMUX/MDEMUX)with low insertion loss and modal crosstalk are the key components.In this paper,a low-modal-crosstalk 4-mode MMUX/MDEMUX for the weakly-coupled triple-ring-core few-mode fiber(TRC-FMF)is designed and fabricated with side-polishing processing.The measurement results show that a pair of MMUX/MDEMUX and 25 km weakly-coupled TRC-FMF MDM link achieve low modal crosstalk of lower than−17.5 dB and insertion loss of lower than 11.56 dB for all the four modes.Based on the TRC-FMF and all-fiber MMUX/MDEMUX,an experiment for 25 km real-time 4-mode 3-λwavelength division multiplexing(WDM)-MDM transmission is conducted using commercial 400G optical transport network(OTN)transceivers.The experimental results prove weakly-coupled MDM techniques facilitate a smooth upgrade of the optical transmission system.
