Multiple deliveries and long turnaround times on construction sites harm the environment and disturb on-site productivity and safety. The purpose of this paper is to investigate the transport patterns of construction material deliveries, including turnaround times. In order to investigate the number of transports and turnaround times, transport data for 13 Swedish construction sites, which were collected with the help of booking systems, were used. By comparing data from the cases, several patterns were observed: (i) very few projects receive deliveries at weekends, (ii) almost all projects receive 50% of their daily deliveries before 09:00, (iii) long goods, standard euro pallets and lightweight goods (less than 500 kg) are the most common deliveries, (iv) trucks and delivery vans are the most common vehicles used and (v) goods to be handled by crane and lightweight goods generate the longest turnaround time/delivery. This is one of the rare studies revealing current practice and issues associated with material deliveries, which is a necessary first step to increase efficiency of construction logistics. This study shows that it is possible to influence these issues, as some projects performed better than others regarding turnaround times and transport.

Abstract The current consensus is that diagnosis and treatment of ependymoma should be based upon clinical and molecular classification. As we move into this paradigm, it is important all ependymoma cases undergo tumor collection, preservation, and molecular profiling at diagnosis. Our group of 6 sites gathered data on a cohort of 72 ependymoma cases. Sites were asked to report known molecular findings; 60/68 eligible cases (88%) did not include genetic findings. The low number of cases with molecular findings was surprising and since cases were diagnosed from as early as 2004, we asked collaborators to share their current practice in profiling (e.g., how frequently; in what setting were ependymomas sent for testing) to try and better understand current practice at sites. Since the publication of ependymoma molecular data, sites with a neuro-oncology program report sending almost all newly diagnosed ependymomas for molecular testing, whereas current practices at sites without dedicated neuro-oncology were less consistent. Profiling in the setting of relapse was more frequently reported at all centers. The implementation of molecular testing at diagnosis may need support at sites without dedicated neuro-oncology. Lead investigators for upcoming ependymoma clinical trials will need to think carefully about the logistics of profiling at centers where this is not standard practice at diagnosis.

Abstract Background: The post-mastectomy changes to the locomotor system are related to the scar and adhesion or to the lymphatic edema after amputation which, in turn, lead to local and global distraction of the work of the muscles. These changes lead to body statics disturbance that changes the projection of the center of gravity and worsens motor response due to changing of the muscle sensitivity. Objective: The aim of the study was to evaluate the static balance of women after undergoing mastectomy. Methods: The study included 150 women, including 75 who underwent mastectomy (mean age: 60±7.6) years, mean body mass index (BMI): 26 (±3.6) kg/m2) and 75 who were placed in the control group with matched age and BMI. The study was conducted using a tensometric platform. Results: Statistically significant differences were found for almost all parameters between the post-mastectomy group and group of healthy women, regarding center of foot pressure (COP) path length in the Y and X axes and the mean amplitude of COP. Conclusions: First, the findings revealed that balance in post-mastectomy women is significantly better than in the control group. Second, physiotherapeutic treatment of post-mastectomy women may have improved their posture stability compared with their peers.

Aim: To assess the knowledge and attitude of students of dental schools in Southern India towards Basic Life Support (BLS), as well as to study the retention of BLS knowledge over time. Subjects and methods: A prevalidated questionnaire was employed, which contains 12 knowledge Questions and five questions designed to assess the students perspective towards BLS. It was hosted on Google Forms, and the URL was distributed to the Students. Results: A total of 267 responses were received, of which 66 were males and 201 were female students. Out of a maximum possible score of 12, the mean knowledge score of the group was 4.54. It was found that those who attended a BLS workshop within the last 2 years scored significantly better than those who either took it more than 2 years ago or had never undergone BLS training. Almost all participants (96%) agreed that there is a need for BLS to be learned by all dental students and hence BLS training should be part of the dental curriculum. 76.8% of respondents expressed reluctance to perform CPR on strangers. Conclusion: The findings show that the dental students who participated in the study had inadequate knowledge in BLS, but had a positive attitude towards the adoption of BLS into the dental curriculum.

BACKGROUND: The early use of statin with intensive regimen has been recommended by the recent guidelines as the prevention of acute coronary syndrome (ACS) related events among the high-risk patients. Meanwhile, the inconsistent statin utilization for targeted patient in current practice is still an issue. AIM: This study aims to review the utilization rate of statin among patients with ACS. METHODS: A systematic search of relevant studies published between inceptions to June 2020 was conducted in PubMed. Patients and intervention domains were used to build up the searching formula. A study was eligible for inclusion if it was an original study of patients with ACS and it examined the utilization of statin. The risk of bias was assessed using Axis and NOS checklist. RESULTS: Among the 49 eligible studies, 38 were cohort studies while the others were cross-sectional studies. The utilization rate of statin at hospital admission ranged from 16% to 61% while 25% to 75% during the hospitalization. Of the total studies, 35 studies reported the statin rate at discharge ranging from 58% to 99%. Almost all studies revealed the reduction of statin utilization rate along the follow-up period. The number of statins prescribed was found to be lower among female and elderly patients. CONCLUSION: Despite the established benefits of statin among patients with ACS, our study revealed that statin was underutilized for secondary prevention after ACS. To improve patients’ clinical outcomes with ACS, efforts should be made to increase optimal treatment and compliance with a statin.

Bioinformatics has pervaded all fields of biology and has become an indispensable tool for almost all research projects. Hence the demand for graduates well-trained in bioinformatics has grown. Teaching bioinformatics has been incorporated in all traditional life science curricula. Better than teaching stand-alone bioinformatics, it would be useful to stress multidisciplinary and problem-solving aspects. Since bioinformatics relies heavily on the use of computers, e-learning is particularly convenient, but few examples have been produced so far. We present a tutorial that starts from a practical problem: finding novel enzymes from marine environments. First, we introduce the idea of metagenomics, a recent approach that extends biotechnology with non-culturable microbes. We then lead the students through databases such as BRENDA, and programs such as BLAST and Clustal Omega. Lastly, we let the students querying these databases about molecules found in marine environments. At the end of the experience, students will have acquired practical knowledge of bioinformatics fundamentals.

Abstract Context.—Timely reporting of outpatient tests can increase efficiency of care and improve customer satisfaction. Objectives.—We conducted a survey in 2002 to determine how quickly hospital-based laboratories turned around routine requests for 3 common assays and compared the results with a similar survey conducted in 1997. Design.—One hundred eighteen laboratories prospectively recorded the collection-to-verification turnaround time for 9252 complete blood cell counts (CBCs), 8832 thyroid tests, and 9193 basic metabolic panels. Results.—The median facility reported all test results by 7:00 am of the weekday immediately after the date of specimen collection. The bottom 10% of institutions reported 99% of CBCs and basic metabolic panels within 1 day and 60% of thyroid tests within 1 day. The 65 institutions that participated in both the 1997 and 2002 surveys showed significant overall improvement in turnaround time for all 3 types of tests (P < .001). In 2002, federal institutions had significantly slower turnaround times than nonfederal institutions for CBC tests (P < .001), thyroid tests (P = .03), and basic metabolic panels (P < .001). Other demographic and practice variables were not associated with turnaround time. Conclusion.—The turnaround time of routine outpatient tests appears to have improved between 1997 and 2002.

AbstractThe projects LIGHT and MIRA are the space-borne and ground-based optical/Infrared-interferometer projects of the National Astronomical Observatory of Japan. The contents of each project are gradually developing, and the descriptions given below are the preliminary ones studied at the present time.LIGHT (Light Interferometer satellite for the studies of Galactic Halo Tracers) is a scanning astrometric satellite for stellar and galactic astronomy planned to be launched between 2007 and 2010 by a M-V launcher of ISAS, Japan. Two sets of Fizeau-type 40cm-pupil interferometers with 1 m baseline are the basic structure of the satellite optics. The multi-color (U, B, V, R, I, and K) CCD arrays are planned to be used in the focal plane of the interferometer, optimized for detecting the precise locations of fringe patterns. LIGHT is expected to observe the parallaxes and proper motions of nearly a hundred million stars up to 18th visual (15thK-band) magnitude with the precision better than 0.1 milli-arcsecond (about 50 microarcsecond in V-band and 90 micro-arcsecond in K-band) in parallaxes and better than 0.1 milli-arcsecond per year in proper motions, as well as the precise photometric characteristics of the observed stars. Almost all of the giant and supergiant stars belonging to the disk and halo components of our Galaxy within 10 to 15 kpc from the sun will be observed by LIGHT to study the most fundamental structure and evolution of the Galaxy. LIGHT will become a precursor of a more sophisticated future astrometric interferometer satellite like GAIA (Lindegren and Perryman, 1996).

Abstract A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners’ dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they play the game. In this paper, we review the experimental literature of the last 20 years on the choice of institutions and describe what has been learned about the quality and the determinants of institutional choice. Cooperative subjects and subjects with optimistic beliefs about others often vote in favor of the institution. Almost all institutions improve cooperation if they are implemented, but they are not always implemented by the players. Institutional costs, remaining free-riding incentives, and a lack of learning opportunities are identified as the most important barriers. Unresolved cooperation problems, like global climate change, are often characterized by these barriers. The experimental results also show that cooperation tends to be higher under endogenously chosen institutions than exogenously imposed institutions. However, a significant share of players fails to implement the institution and they often perform poorly, which is why we cannot conclude that letting people choose is better than enforcing institutions from outside.

Abstract In weather and climate sciences ensemble forecasts have become an acknowledged community standard. It is often found that the ensemble mean not only has a low error relative to the typical error of the ensemble members but also that it outperforms all the individual ensemble members. We analyze ensemble simulations based on a simple statistical model that allows for bias and that has different variances for observations and the model ensemble. Using generic simplifying geometric properties of high-dimensional spaces we obtain analytical results for the error of the ensemble mean. These results include a closed form for the rank of the ensemble mean among the ensemble members and depend on two quantities: the ensemble variance and the bias both normalized with the variance of observations. The analytical results are used to analyze the GEFS reforecast where the variances and bias depend on lead time. For intermediate lead times between 20 and 100 h the two terms are both around 0.5 and the ensemble mean is only slightly better than individual ensemble members. For lead times larger than 240 h the variance term is close to 1 and the bias term is near 0.5. For these lead times the ensemble mean outperforms almost all individual ensemble members and its relative error comes close to −30%. These results are in excellent agreement with the theory. The simplifying properties of high-dimensional spaces can be applied not only to the ensemble mean but also to, for example, the ensemble spread.

Objective To determine the precision and accuracy of facial anthropometric measurements obtained through digital three-dimensional (3D) photogrammetry. Design Nineteen standard craniofacial measurements were repeatedly obtained on 20 subjects by two independent observers, using calipers and 3D photos (obtained with a Genex 3D camera system), both with and without facial landmarks labeled. Four different precision estimates were then calculated and compared statistically across techniques. In addition, mean measurements from 3D photos were compared statistically with those from direct anthropometry. Results In terms of measurement precision, the 3D photos were clearly better than direct anthropometry. In almost all cases, the 3D photo with landmarks labeled had the highest overall precision. In addition, labeling landmarks prior to taking measurements improved precision, regardless of method. Good congruence was observed between means derived from the 3D photos and direct anthropometry. Statistically significant differences were noted for seven measurements; however, the magnitude of these differences was often clinically insignificant (< 2 mm). Conclusions Digital 3D photogrammetry with the Genex camera system is sufficiently precise and accurate for the anthropometric needs of most medical and craniofacial research designs.
