1、Interaction Effects of Combinations of Relevance and Execution StyleObjectivesThis study assessed the diagnostic performance of coronary computed tomography angiography (CTA) for the detection and exclusion of significant coronary artery stenosis as remotely interpreted on a mobile handheld device w

2、ith dedicated medical imaging software. BackgroundRecent advances in technology now permit remote interpretation of medical imaging studies on mobile handheld devices, although the diagnostic performance of this approach is unknown. MethodsWe evaluated 102 patients with stable chest pain and both 64

3、-detector row coronary CTA and quantitative invasive coronary angiography. The diagnostic performance of remote coronary CTA interpretation was assessed using a mobile handheld device and employing dedicated software. The coronary CTA studies were examined in an intent-to-diagnose manner for the pre

4、sence or absence of coronary artery stenosis 50% on a per-artery and per-patient level; results were compared with quantitative invasive coronary angiography. Two blinded imagers independently interpreted coronary CTA studies, with a third imager achieving consensus for discordance. Coronary CTAs we

5、re re-interpreted in random order to determine interobserver agreement. Finally, coronary CTAs were evaluated on a dedicated 3-dimensional imaging workstation; results were compared to mobile handheld device findings for intertechnology agreement. ResultsThe prevalence of significant coronary artery

6、 stenosis was 25% (26 of 102) at the per-patient level and 10% (40 of 405) at the per-artery level. Per-patient and per-artery sensitivity, specificity, and positive and negative predictive values were: 100% (26 of 26), 78% (59 of 76), 60% (26 of 43), and 100% (59 of 59), respectively; and 95% (38 o

7、f 40), 85% (310 of 365), 41% (38 of 93), and 99% (310 of 312), respectively. At the per-artery level, interobserver, intraobserver, and intertechnology agreement was 0.74, 0.89, and 0.75, respectively (p 0.01 for all). ConclusionsThe interpretation of coronary CTA using a mobile handheld device with

8、 dedicated software for medical image evaluation possesses high diagnostic accuracy for detection and exclusion of significant coronary stenosis.Dialectical behavior therapy (DBT) has received strong empirical support and is practiced widely as a treatment for borderline personality disorder (BPD) a

9、nd BPD with comorbid substance use disorders (BPD-SUD). Therapeutic success in DBT requires that individuals generalize newly acquired skills to their natural environment. However, there have been only a limited number of options available to achieve this end. The primary goal of this research was t

10、o develop and test the feasibility of the DBT Coach, a software application for a smartphone, designed specifically to enhance generalization of a specific DBT skill (opposite action) among individuals with BPD-SUD. We conducted a quasiexperimental study in which 22 individuals who were enrolled in

11、DBT treatment programs received a smartphone with the DBT Coach for 10 to 14 days and were instructed to use it as needed. Participants used the DBT Coach an average of nearly 15 times and gave high ratings of helpfulness and usability. Results indicate that both emotion intensity and urges to use s

12、ubstances significantly decreased within each coaching session. Furthermore, over the trial period, participants reported a decrease in depression and general distress. Mobile technology offering in vivo skills coaching may be a useful tool for reducing urges to use substances and engage in other ma

As advances are being made the electrical energy consumption

14、 of telecommunication equipments is ever increasing and thereby increasing its dissipation rate. In addition such shelters are installed in remote areas, so cooling of telecom shelters becomes a great challenge for thermal engineers. A field study revealed conventional cooling systems are not so eff

15、ective in terms of energy consumption and in the absence of power grid, shelters installed in such areas require additional capital cost to provide power for cooling system. A new passive cooling system incorporating phase change material (PCM) and two-phase closed thermosyphon (TPCT) heat exchanger

16、s has been developed and experimented to provide thermal management for telecommunication equipments housed in telecom shelters. The newly developed thermal system absorbs the equipment dissipated heat during the hottest part of the day, stores it as latent heat and releases it through thermosyphons

17、 during the night to the ambient.To test the feasibility of short message service (SMS) usage between the clinic visits and to evaluate its effect on glycemic control in uncontrolled type 2 Diabetes Mellitus (DM) subjects. Research design and methods34 cases with type 2 Diabetes were followed after

18、fulfilling the inclusion criteria. The interventional group (n = 12) had the same conventional approach of the control group but had two mobile numbers (physician and diabetic educator) provided for the SMS support until their next visit in 3 months. Both groups of age, BMI and the pre-study A1c wer

19、e comparable. ResultsBoth groups had a significant reduction in their A1c compared to their baseline visit. However, the interventional group had significantly greater reduction in A1c (p = 0.001), 1.16% lower than controls. The service was highly satisfactory to the group. ConclusionThe results ind

20、icate effectiveness in lowering A1c and acceptance by the patients. Further research and large-scale studies are needed.The traditional Random Digit Dialing method (list-assisted RDD using a frame of landline phone numbers) is clearly under threat. The difficulty and costs of completing telephone su

21、rveys have increased due to rising rates of refusal and non-contact. The completeness of coverage of list-assisted RDD samples has diminished due to the proliferation of cell-phone only households. The ability of list-assisted RDD to capture young, mobile, unmarried, and minority households is thus

22、diminishing as well. Increasingly, survey researchers have been adding a cell phone component to their sampling frames for telephone surveys, despite the increased costs and other issues associated with RDD calling of cell phones. Recent research by Guterbock, Oldendick, and others has explored the

23、extent to which “electronic white pages” (EWP) samples really differ from RDD samples. Oldendick et al. and Guterbock, Diop and Holian have emphasized that minority households are seriously underrepresented in EWP samples. Nevertheless, EWP samples have distinct advantages whenever a survey is aimed

24、 at a restricted geographic area. This paper considers the feasibility of combining EWP samples with cell-phone RDD, eliminating the ordinary RDD component from the sampling frame. We analyze the components of the telephone population, showing that the proposed method would fail to cover only one se

25、gment of the telephone population: unlisted landline households that have no cell phone. We analyze data from the 2006 National Health Interview Study to estimate the size of this segment, its demographic profile, the degree to which selected demographic and health behavior characteristics are diffe

26、rent from those in the segments that this sampling strategy would capture, and what biases are present in the various sampling frames of interest. Trend data from the NHIS are used to assess how these biases are changing. A simple cost comparison is made among the RDD, RDD + cell and EWP + cell fram

27、es. The proposed alternative “EWP + cell” sampling frame provides relatively small bias compared to RDD + cell at costs comparable to RDD-only designs. The portion of the telephone universe that is excluded in the EWP + cell design is getting smaller all the time, therefore its bias relative to the

28、RDD + cell design is decreasing over time. Overall, the EWP + cell design seems to be a useful alternative.rapid growth of e-commerce has confronted both enterprises and consumers with a new situation. Whereas companies are finding it harder to survive, consumers are unable to effectively select the

29、 products that really to meet their needs. To reduce the product overload of Internet shoppers, a variety of recommendation techniques that track previous actions of groups of consumers to make personalized recommendations have been developed and applied. Current personalized recommendation systems

30、suffer from the need to analyze large sets of consumer data, or data for numerous consumers. However, even within a single group, consumer preferences may differ, and individual preferences may also change with circumstances. Additionally, the consumer product knowledge influences their browsing act

31、ions. To orient Web-visitors on how to become consumers, a salesman-like recommendation technology was developed based on visitor product preference index, which comprises of their product knowledge and browsing actions in scene. A prototype system for use with high-technology product, 3G phones, wa

32、s developed to test the effectiveness of the recommendation technology. Through a test of 250 objectives, the results show that the recommendation deviation level can be reduced to 0.49, and exact fit with visitor favor products can reach 60.8%, showing that the proposed model can achieve recommenda
