附加的 赚钱的

对于每一个人来说,“小人”都是一个极端的蔑称。所谓“两面三刀、阳奉阴违”,人人都敬而远之,古龙在其书中说到,他最痛恨的就是“嘴里叫哥哥,手里捅刀子”的家伙。猫王的一位朋友就曾有感而发:“千万不要轻信那些表面的现象,也不要被那些甜言蜜语所迷惑,不了解实际情况决不能轻易下手。那些奸商……”朋友很是愤怒,因为他受过骗。那年,他要买打印机,“就想买个耐用的,便宜点的。”于是,这老兄四处查找信息,终于在某杂志上找到他所中意的对象,便宜、耐用、不偏不倚。朋友打电话去询问,销售小姐很热情,各项情况娓娓道来,并保证广告所说一切属实,敬请现场查看。朋友一时喜不自禁,第二天就驱车前

适合的才是好的

任何一个产业,在刚刚起步阶段,国家的保护是至关重要的,这会促进这个产业的快速发展,但我们不能始终躺在国家庇护的树荫下乘凉,要主动去适应市场。     

合适的才是好的

夏天的天气简直熱得都快要赶上e浪潮了,让e诸葛实在有点不受用。于是乎,e诸葛抽了个空到大商场去查探了一番。虽然这不是一个大老爷们愿意干的事,但是既然是“微服私访”,就有几个原因:一是想吹吹空调,吸吸凉气,驱走烦躁;二是想在商场中找寻一些关于传统零售业迟迟不肯进入电子商务的蛛丝马迹。走了走大商场.他好象明白了其中一二。都说“购物是一种享受”,大概只有抱着研究的心态,e诸葛才注意到:商场中不但有凉爽的环境、柔和的灯光、优美的音乐,就连货物的摆放、位置也有讲究。似乎大型商场一层总是化妆品和首饰,二、三层铁定是男装女装,超市嘛,肯定在地下……这就是传统商家的一些经验吧。有层次感、丰富多样的物品加上员工的服务态度……加在一起     

小的才是好的

前年秋天,我奉学校之派,到韩国圆光大学任教.刚刚跨入大学为我安排的宿舍,就发现写字桌上放着一台半新不旧的电脑.这可真是喜出望外.在家里我用惯了电脑,这一下可免除了无“脑”的烦恼.一喜之下,我马上又关心起圆光大学的网络设施问题.能不能方便快捷地上因特网,这可关系我在韩国的生活质量.因为身在异国,中文的报刊杂志少而又少.好不容易看到《人民日报》海外版,往往是个把星期以前的旧闻.只要能上网,看看国内的网上报章,无疑会解除文化信息的干渴.

RFID-based indoor location tracking to ensure the safety of the elderly in smart home environments

In recent years, the number of elderly people living alone has grown rapidly. This increases the need for indoor healthcare services that help elderly residents live a safe and independent life. There has been increasing interest in indoor ubiquitous healthcare (U-Healthcare) applications that monitor the elderly unobtrusively via sensors and that warn them or healthcare providers of abnormal conditions. In U-Healthcare applications, automatically locating and tracking users who move around a building is a fundamental feature. Outdoor location sensing technologies such as the global positioning systems are not suitable for use in indoor environments, such as “smart home” applications, because their indoor-based location sensing lacks accuracy. This paper proposes an indoor U-Healthcare system that uses radio-frequency identification technology to accurately locate and track the elderly. The proposed system provides real-time monitoring of elderly people’s whereabouts. In addition, it analyzes their locations in association with time slots and the length of time they stay in the same place, thus inferring information such as movement patterns, ranges, and frequencies. This information is used to determine elderly people’s well-being and to warn family or healthcare workers of any potential problems. The proposed indoor U-Healthcare system improves the quality and convenience of care delivered to elderly people.

RFID Positioning and Physiological Signals for Remote Medical Care

The safety of patients and the quality of medical care provided to them are vital for their wellbeing. This study establishes a set of RFID (Radio Frequency Identification)-based systems of patient care based on physiological signals in the pursuit of a remote medical care system. The RFID-based positioning system allows medical staff to continuously observe the patient's health and location. The staff can thus respond to medical emergencies in time and appropriately care for the patient. When the COVID-19 pandemic broke out, the proposed system was used to provide timely information on the location and body temperature of patients who had been screened for the disease. The results of experiments and comparative analyses show that the proposed system is superior to competing systems in use. The use of remote monitoring technology makes user interface easier to provide high-quality medical services to remote areas with sparse populations, and enables better care of the elderly and patients with mobility issues. It can be found from the experiments of this research that the accuracy of the position sensor and the ability of package delivery are the best among the other related studies. The presentation of the graphical interface is also the most cordial among human-computer interaction and the operation is simple and clear.

VCNI – Applying value theory to contextual needs identification in proactive elderly care

This paper presents a novel needs-identification system (named VCNI) that is a context-aware and value-perspective for proactive elderly care (that considers certain quality elements as consumer participation, caregiver involvement, and continuous quality improvement). We apply the value theories and principles and devise a novel method (conflict resolution algorithm) aiming for allocating an agent team with the least value conflict fashion so as to discover the contextualized mission that could fulfill the needs of the elderly. With the context information reported by pervasive components, this system can proactively provide the directions of the individualized assistance required for the elderly in maintaining an independent lifestyle and reduce possible health-care costs. To show the feasibility of the methodology proposed in the paper, a prototype system has been implemented for justifying the capability of the system’s needs identification from the macro and micro perspectives. Moreover, our system also exemplifies a future way of service provision on electronic care.     

Care robots and the future of ICT-mediated elderly care: a response to doom scenarios

The discussion about robots in elderly care is populated by doom scenarios about a totally dehumanized care system in which elderly people are taken care of by machines. Such scenarios are helpful as they attend us to what we think is important with regard to the quality elderly care. However, this article argues that they are misleading in so far as they (1) assume that deception in care is always morally unacceptable, (2) suggest that robots and other information technologies necessarily deceive elderly people by creating a “virtual” world as opposed to a “real” world, (3) assume that elderly people of the future have similar ICT skills and interests as the elderly people of today, and (4) assume a simplistic view of technologies. The article suggests an approach to evaluating care robots and ICT in health care which acknowledges and addresses a number of ethical problems raised by robotic care—for instance disengagement problems—while taking into account that some elderly people may need care that does not treat them as (empirically) autonomous, that many the elderly of the future are likely to be digital natives, and that the task of evaluating technologies in care is more complicated than the discussion of deception suggests.

The study of path error for an omnidirectional home care mobile robot

The first objective of this research was to develop an omnidirectional home care mobile robot. A PC-based controller controls the mobile robot platform. This service mobile robot is equipped with an “indoor positioning system” and an obstacle avoidance system. The indoor positioning system is used for rapid and precise positioning and guidance of the mobile robot. The obstacle avoidance system can detect static and dynamic obstacles. In order to understand the stability of a three-wheeled omnidirectional mobile robot, we carried out some experiments to measure the rectangular and circular path errors of the proposed mobile robot in this research. From the experimental results, we found that the path error was smaller with the guidance of the localization system. The mobile robot can also return to its starting point. The localization system can successfully maintain the robot’s heading angle along a circular path.
