An opinion paper: Investigating Quality of Service Concerning the RFB Protocol and its Application in Cloud Gaming

Remote Framebuffer (RFB) protocol is a simple protocol for remote access to graphical user interfaces. The use of the RFB protocol has been developed as a means of streaming content, alleviating much of the processing requirements of games for the end user. Cloud gaming is currently an area of the gaming industry gaining large amounts of ground with respect to the potential viability in the future. Understanding how QoS can affect the development of cloud gaming, as well as the metrics involved, and how these metrics affect areas surrounding QoE could help aid developments in cloud gaming as an extremely viable process in the future

Complementary and alternative therapies to relieve labor pain: A comparative study between music therapy and Hoku point ice massage.

BACKGROUND & AIM Pain is a common experience for women during labor. In the present study, we compared the effect of two types of non-pharmacological pain relief methods "music therapy" and "Hoku point ice massage" on the severity of labor pain. METHODS This prospective, randomized, controlled trial was conducted in Shahrekord, Iran, from September 2013 to June 2014. We randomly assigned 90 primiparous women who expected a normal childbirth into three groups: group "A" received music therapy, group "B" received Hoku point ice massage, and group "C" received usual labor care. At the beginning of the active phase (4 cm cervical dilation) and before and after each intervention (at dilations 4, 6, and 8 cm), the intensities of labor pain were measured using Visual Analogue Scale (VAS). RESULTS At the beginning of the active phase, the mean VAS scores were 5.58 ± 1.29, 5.42 ± 1.31, and 6.13 ± 1.37 in the women in groups "A," "B," and "C," respectively (P > 0.05). After the intervention, the mean pain scores were significantly lower at all of the time points in groups "A" and "B" than in group "C" women (P  0.05). CONCLUSIONS Music therapy and Hoku point ice massage are easily available and inexpensive methods and have a similar effect in relieving labor pain

Migration of cloud services and deliveries to higher education

This paper discusses the adoption of cloud computing in education. It emphasizes the view that cloud computing is vital in the education sector because of its ability to reduce the overall costs of IT infrastructure installation and maintenance, improvement of efficiency, and the sharing of IT resources among students. The flexibility of cloud computing and its reliability makes it more appropriate for use in the educational environment. The Leeds Beckett University cloud project utilizes the SAS Educational Value-Added Assessment System, which gives lecturers the opportunity to deliver accurate content to students while monitoring their progress. Contemporary educational institutions must look forward to improve their research and education through cloud computing

Elective induction of labor versus spontaneous labor in Hajar hospital, Shahrekord

Background and aim: With attention to increasing of the early hospitalization of women, induction of labor and its complications, the present study designed to compare the elective induction and spontaneous labor considering the mother and infant outcome. Methods: In a prospective and analytical study using of questionnaire and check list, 50 nulliparous women who were hospitalized for elective induction were compared with 50 nulliparous women with spontaneous labor in terms of Bishop score of cervix, duration of labor stages, number of vaginal examinations, intensity of uterine contractions, fetal distress, mode of delivery, Apgar score and birth weight of infants. The exclusion criteria were, multifetal pregnancy, abnormal presentation, premature rupture of membrane, preterm labor and placenta abruption. Data analyzed by t, Chi square and Pearson correlation tests. Results: There was no significant difference between two groups in terms of age, job and gestational age, mean of duration of labor stages, number of vaginal examinations, birth weight and Apgar score. In 98% of women with induced labor, Bishop score was <5. In this study group tetanic contractions, fetal distresses and cesarean sections were more than those of women with spontaneous labor (p<0.001). Conclusion: Elective induction of labor must be applied when there is a medical indication for termination of pregnancy. Onetime admission of women for delivery and change the women’s attitude towards the benefits of spontaneous labor and complications of elective induction are suggestive ways until they decide with knowledge and select these methods

EFFECT OF VITEX ON HOT FLASH OF MENOPAUSAL WOMEN REFERRED TO HEALTH CENTER OF ISFAHAN

Background and Aim: Menopause is a period in women’s lives that is accompanied with outcomes and effects which can adversely affect on the quality of life and weaken well-being. The most widely recognized outcome of menopause is hot flash that adversely affects on work, social activities, enjoying life, sleep, andin sum- total quality of living. The common treatment of this symptom is hormone treatment (HRT) which has some adverse effects and sometimes some contraindications. The present study aimed at assessing the effect of Vitex on hot flash. Materials and Methods: This double –blind and clinical trial was performed on 54 women with hot flash aged between 45 and 55 years in Isfahan in 2002, which had been referred for treatment. The population was randomly divided into 2 groups: 1) taking Vitex 2) control group, taking placebos. Data collection was done through interviews and a questionnaire considering demographic and hot flash characteristics (using Kupperman Index), which was filled out for each woman. Hot flash was assessed in three stages .The obtained data was analysed by means of SPSS software, descriptive and inferential statistics; and P%0.05 was taken as the significant level. Results: It was found that there was a significant difference in severity of hot flash before and after treatment in vitex group (P<0.012).While the difference was not significant after treatment in the placebo group. (P>0.05).Comparing the two groups with respect to severity of hot flash after treatment revealed a significant statistical difference (P<0.05); though the difference was not significant before treatment. Conclusion: Vitex can act as an alternative in treating menopausal hot flash; particularly in those who cannot safely bear hormonal treatment

Theoretical and experimental study of performance anomaly in multi-rate IEEE802.11ac wireless networks

IEEE 802.11 wireless local area networks (WLANs) are shared networks, which use contention-based distributed coordination function (DCF) to share access to wireless medium among numerous wireless stations. The performance of the distributed coordination function mechanism mostly depends on the network load, number of wireless nodes and their data rates. The throughput unfairness, also known as performance anomaly is inherent in the very nature of mixed data rate Wi-Fi networks using the distributed coordination function. This unfairness exhibits itself through the fact that slow clients consume more airtime to transfer a given amount of data, leaving less airtime for fast clients. In this paper, we comprehensively examine the performance anomaly in multi-rate wireless networks using three approaches: experimental measurement, analytical modelling and simulation in Network Simulator v.3 (NS3). The results of our practical experiments benchmarking the throughput of a multi-rate 802.11ac wireless network clearly shows that even the recent wireless standards still suffer from airtime consumption unfairness. It was shown that even a single low-data rate station can decrease the throughput of high-data rate stations by 3–6 times. The simulation and analytical modelling confirm this finding with considerably high accuracy. Most of the theoretical models evaluating performance anomaly in Wi-Fi networks suggest that all stations get the same throughput independently of the used data rate. However, experimental and simulation results have demonstrated that despite a significant performance degradation high-speed stations still outperform stations with lower data rates once the difference between data rates becomes more significant. This is due to the better efficiency of the TCP protocol working over a fast wireless connection. It is also noteworthy that the throughput achieved by a station when it monopolistically uses the wireless media is considerably less than 50 % of its data rate due to significant overheads even in most recent Wi-Fi technologies. Mitigating performance anomaly in mixed-data rate WLANs requires a holistic approach that combines frame aggregation/fragmentation and adaption of data rates, contention window and other link-layer parameters

Developing a fuzzy expert system to predict the risk of neonatal death

Introduction: This study aims at developing a fuzzy expert system to predict the possibility of neonatal death. Materials and Methods: A questionnaire was given to Iranian neonatologists and the more important factors were identified based on their answers. Then, a computing model was designed considering the fuzziness of variables having the highest neonatal mortality risk. The inference engine used was Mamdani's method and the output was the risk of neonatal death given as a percentage. To validate the designed system, neonates' medical records real data at a Tehran hospital were used. MATLAB software was applied to build the model, and user interface was developed by C# programming in Visual Studio platform as bilingual (English and Farsi user interface). Results: According to the results, the accuracy, sensitivity, and specificity of the model were 90, 83 and 97, respectively. Conclusion: The designed fuzzy expert system for neonatal death prediction showed good accuracy as well as proper specificity, and could be utilized in general hospitals as a clinical decision support tool. ©2016 Reza Safdari, Maliheh Kadivar, Mostafa Langarizadeh, Ahmadreaza Farzaneh Nejad, Farzaneh Kermani

Educational needs of midwife alumni work in health care centers

Abstract Aims: Determination of educational needs is the first step in educational planning and the first factor of ensuring the quality and efficacy of education process. Midwives’ sufficient knowledge and improvement of their decision-making will lead to performance progress. The aim of this study was determining the educational needs of midwives working in hospitals and healthcare centers of Chaharmahal & Bakhtiari province. Methods: This cross-sectional study was performed on 280 midwives and 50 healthcare center authorities of hospitals and healthcare centers of Chaharmahal & Bakhtiari who were selected by census sampling method in 2009. Data was collected by a researcher-made questionnaire containing three sections of demographic characteristics, educational needs related to their specialty or general domains and priority in educational needs. Data were analyzed by descriptive statistics and Chi-square, student T-test and one-way ANOVA using SPSS 15 software. Results: There wasn’t significant difference in the average scores of educational needs in specific and general domains from authorities and midwives’ point of view (p>0.05). There was a significant relationship between the average score of educational needs and work place in obstetrics (p=0.002), maternal and child health (p=0.038) and neonatal (p=0.025) domains. There was a significant relationship between the average score of educational needs and the academic level of education in general domains (p=0.025). Conclusion: Holding educational classes of English, use of Information Technology (IT) in obstetrics, resuscitation, research methodology, religious and legal commandments, abnormal uterine bleeding, hypertensive disorders, neonatal medical treatment and common gynecologic infections seems essential as educational priorities.

Evaluation of patient outcome and satisfaction after surgical treatment of adolescent idiopathic scoliosis using scoliosis research society-30

Background: Adolescent idiopathic scoliosis (AIS) may lead to physical and mental problems. It also can adversely affect patient satisfaction and the quality of life. In this study, we assessed the outcomes and satisfaction rate after surgical treatment of AIS using scoliosis research society-30 questionnaire (SRS-30). Methods: We enrolled 135 patients with AIS undergoing corrective surgery. Patients were followed for at least 2 years. We compared pre- and post-operative x-rays in terms of Cobb's angles and coronal balance. At the last visit, patients completed the SRS-30 questionnaire. We then assessed the correlation between radiographic measures, SRS-30 total score, and patient satisfaction. Results: Cobb's angle and coronal balance improved significantly after surgery (P<0.001). The scores of functional activity, pain, self-image/cosmesis, mental health, and satisfaction were 27±4.3, 26±2.5, 33±5.2, 23±3.5, and 13±1.8, respectively. The total SRS-30 score was 127±13. Radiographic measures showed significant positive correlation with satisfaction and SRS-30 total scores. There was also a positive correlation between satisfaction and self-image/cosmesis domain scores. Conclusions: The greater the radiographic angles were corrected the higher the SRS-30 total score and patient satisfaction were. It is intuitive that the appearance and cosmesis is of most important factor associated with patient satisfaction. © 2015 BY THE ARCHIVES OF BONE AND JOINT SURGERY
