The likelihood of occurrence and the magnitude of risk for each of these surgical safety events are undefined. Many providers may never have a personal experience with one of these events and training and education on these topics are sparse. These circumstances lead to faulty thinking that a provider won't ever have an event or if one does occur the provider will intuitively know what to do. Surgeons are not preoccupied with failure and tend to usually consider good outcomes, which leads them to ignore or diminish the importance of implementing and following simple safety practices. These circumstances contribute to the persistent low level occurrence of these three events and to the difficulty in generating sufficient interest to resource solutions. Individual facilities rarely have the time or talent to understand these events and develop lasting solutions. More often than not, even the most well meaning internal review results in a new line to a policy and some rigorous enforcement mandate. This approach routinely fails and is another reason why these problems are so persistent. Vigilance actions alone havebeen unsuccessful so hospitals now have to take a systematic approach to implementing safer processes and providing the resources for surgeons and other stake-holders to optimize the OR environment. This article discusses standardized processes of care for mitigation of injury or outright prevention of wrong site surgery, RSI and surgical fires in an action-oriented framework illustrating the strategic elements important in each event and focusing on the responsibilities for each of the three major OR agents-anesthesiologists, surgeons and nurses. A Surgical Patient Safety Checklist is discussed that incorporates the necessary elements to bring these team members together and influence the emergence of a safer OR.展开更多

Interview and observation were used in collecting the needed data at selected craft centres in the Kwabre East District, Ejisu-Juaben municipality, Kumasi sub-metro and metropolitan in the Ashanti region of Ghana. The study employed both descriptive and experimental research methods based on the qualitative research approach. It was revealed that Kente and Adinkra enjoy wide reputation and therefore are considered as prestigious clothes. However, Nwomu cloth does not have this fame, only indigenes understand its usage and the philosophy behind its production. In view of this, it is recommended that the elders who are endowed with this unique craft must open their doors to the youth to learn the craft.展开更多

For safety with service robots working in a space where people live, some notification before collision with an obstacle is desirable. To achieve such a function, we developed a master-slave manipulator system in which the slave manipulator surface is covered with many proximity sensors. Additionally, we developed a haptic device that feeds back proximity sense information to the operator using small vibration motors. We attached the haptic device to the arm of the operator and vibrated the vibration motor corresponding to the sensor. Thereby, the operator was able to ascertain the position of an object near the manipulator, and to make the robot maneuver to avoid it before collision. To confirm the system usefulness, we equipped subjects with the developed proximity sense presentation device and performed a detection-position-specific experiment and an obstacle avoidance experiment in a narrow space. As results of the detection position specific experiment on five subjects, four subjects reported the detection position correctly. The remaining one person failed because of his particular arm shape. Operation experiments conducted in a narrow space showed that all subjects＇ work was successful when given feedback of proximity sense information. Nobody was successful without proximity sense information. Results of these two experiments demonstrate that this proposed system is useful for obstacle avoidance of a master-slave manipulator system.展开更多

The major drivers of mobile computing are large number of mobile phone users. As their number is increasing worldwide, different organizations are offering their services using the mobile devices. Oman is a developing country that strives to adapt M-services. The number of mobile phone users in Oman increased substantially since its launch in 1996. Prepaid mobile services and SMS （Short Message Services） were introduced in 2001 and both are currently popular with subscribers. Such fine appeal influenced many government organizations to go mobile with their services. This paper describes the SMS-Parking service, which is introduced recently by a joint venture of the Muscat Municipality and the Oman Mobile company offering mobile services to its citizens and reports the initial feedback of its users. This study shows that the new service is not yet popular among its users and may need their more positive attitudes toward it for its quick adoption.展开更多

Compared to western countries, design works of China have obvious disadvantages. At the same time, the traditional handicraft techniques of China have suffered strong blows of modem technologies with the development of time and their living space have been gradually occupied. The combination of traditional handicraft techniques with modem fashion design has dual significances. On the one hand, it helps infuse new ideas into fashion design. On the other hand, it promotes the development of traditional handicraft techniques in modern times. In this respect, this combination has some positive significances.展开更多

The aim is to develop a form of technical assistance that supports them in the control of schedules, prevention of dangerous areas in the work place, warnings and automatic alarm generation. The device chosen to exchange all this information is a smartphone based on Android Operating System and GPS （Global Positioning System） technology mainly. A set of Android applications has been developed using Java language, and controlling the device via Google-developed Java libraries. All of them are connected to the Server Application through the Communications Module. The Server Application Module provides the assistants or psychologists the possibility of supervise all the handicapped people activities. The assistants, psychologists and users have all evaluated the application very positively as it covers disabled people＇s needs perfectly.展开更多

The Chinese knock-off wireless handset industry has succeeded in building a miniature version of an NVC based on the Huaqiangbei Market, a typical specialized market. ＂Ihis paper begins b）, analyzing the differences in the industrial chains of knock-off and traditional wireless handsets and concludes that due to lacking after-sales service, the value chain of knock-off wireless handsets is consumer-driven, with a focus on manufacturing and marketing. Analysis of the knock-off wireless handset-based NVC reveals that multi-level demands, a maturing industry and adaptive innovation are three pre-conditions for Chinese manufacturing to build an NVC in a two-sided market. Given the uneven scale and techniques among knock-off handset makers, their addiction to the low-end market and imperfect value chains constructed using the ＂knockoff pattern＂ this paper proposes that China can break these bottlenecks by letting the specialized and unilateral markets develop closer to each other and by providing governmental guidance in the specialized market.展开更多
