The Effects of Friction on the Performance of A Concrete Block Mine Seal with Pressurized Grout Bags
Authors: Perry Kyle A. 
Published: November 2014

Abstract
Mine seals are necessary in nearly every underground coal mine to isolate mined-out areas from the ventilation network. Many seals are already in place in active mines and more need to be constructed to keep up with the development of underground coal reserves. The accidents involving seal failures at Sago and Darby prompted MSHA to create and implement new regulations regarding the strength of the seals. These regulations require the design and construction of seals that are larger and stronger than ever before. Structural seals capable of withstanding the new required design loads are now designed by an engineer and no longer approved through explosion testing.
Prior to the seal failure accidents, a solid-block wall with pressurized grout bags at the wall/ribs and wall/roof interfaces was a popular design which met the 137.9 kPa (20 psi) requirement. After implementation of the new 344.7 kPa (50 psi) or 827.4 kPa (120 psi) design regulations depending on whether the atmosphere is kept inert inby the seal, a re-design of the seal was necessary. This paper discusses the quantification of the coefficients of friction which are then implemented into finite element modeling.

AbstractEthylhexyl-methoxy cinnamate (EHMC), an ultraviolet (UV) filter that absorbs solar UVB radiation is frequently used in the formulation of sunscreens and cosmetics. Except for the controlled UV filter application studies, no general population studies on the magnitude and variability of exposures to EHMC exist. Given the widespread use of UV filters in consumer products, a pilot human biomonitoring study was undertaken to: i) determine the concentrations of EHMC in urine samples of young adults, and ii) investigate the association between consumption patterns of selected consumer products and urinary EHMC concentrations. A group of 48 randomlyselected volunteers provided a first morning urine void and a questionnaire on the types and usage patterns of sunscreens and cosmetics was administered to them. Significantly (p=0.006) higher urinary EHMC levels were observed in females, and in users of face sunscreens (p=0.008) and lipsticks (p=0.003). Linear multiple regression analysis showed that the frequency of use of face sunscreens (all year) (p=0.02) and gender (females) (p=0.03) were significant predictors of creatinine-adjusted urinary EHMC levels in the pooled sample, even after adjusting for relevant covariates, such as age, body-mass index and the number of cosmetics used. A larger sample could help us further evaluate the observed trends.

Numerical Implementation of the Fictitious Domain Method for Elliptic Equations
Authors: Temirbekov Almas N. , Wójcik Waldemar 
Published: November 2014

Abstract
In this paper, we consider an elliptic equation with strongly varying coefficients. Interest in the study of these equations is connected with the fact that this type of equation is obtained when using the fictitious domain method. In this paper, we propose a special method for the numerical solution of elliptic equations with strongly varying coefficients. A theorem is proved for the rate of convergence of the iterative process developed. A computational algorithm and numerical calculations are developed to illustrate the effectiveness of the proposed method.

Authors: Griessenauer Christoph J. , Salam Smeer , Hendrix Philipp , Patel Daxa M. , Tubbs R. Shane , Blount Jeffrey P. , Winkler Peter A. 
Published: November 2014

OBJECT
Evidence in support of hemispherectomy stems from a multitude of retrospective studies illustrating individual institutions' experience. A systematic review of this topic, however, is lacking in the literature.

METHODS
A systematic review of hemispherectomy for the treatment of refractory epilepsy available up to October 2013 was performed using the following inclusion criteria: reports of a total of 10 or more patients in the pediatric age group (≤ 20 years) undergoing hemispherectomy, seizure outcome reported after a minimum follow-up of 1 year after the initial procedure, and description of the type of hemispherectomy. Only the most recent paper from institutions that published multiple papers with overlapping study periods was included. Two reviewers independently applied the inclusion criteria and extracted all the data.

RESULTS
Twenty-nine studies with a total of 1161 patients met the inclusion criteria. Seizure outcome was available for 1102 patients, and the overall rate of seizure freedom at the last follow-up was 73.4%. Sixteen studies (55.2%) exclusively reported seizure outcomes of a single type of hemispherectomy. There was no statistically significant difference in seizure outcome and type of hemispherectomy (p = 0.737). Underlying etiology was reported for 85.4% of patients with documented seizure outcome, and the overall distribution of acquired, developmental, and progressive etiologies was 30.5%, 40.7%, and 28.8%, respectively. Acquired and progressive etiologies were associated with significantly higher seizure-free rates than developmental etiologies (p < 0.001). Twenty of the 29 studies (69%) reported complications. The overall rate of hydrocephalus requiring CSF diversion was 14%. Mortality within 30 days was 2.2% and was not statistically different between types of hemispherectomy (p = 0.787).

CONCLUSIONS
Hemispherectomy is highly effective for treating refractory epilepsy in the pediatric age group, particularly for acquired and progressive etiologies. While the type of hemispherectomy does not have any influence on seizure outcome, hemispherotomy procedures are associated with a more favorable complication profile.
Experience with intrawound vancomycin powder for posterior cervical fusion surgery
Authors: Martin Joel R. , Adogwa Owoicho , Brown Christopher R. , Kuchibhatla Maragatha , Bagley Carlos A. , Lad Shivanand P. , Gottfried Oren N. 
Published: November 2014

OBJECT
Recent studies have reported that the local delivery of vancomycin powder is associated with a decrease in spinal surgical site infection. This retrospective cohort study compares posterior cervical fusion cases before and after the routine application of spinal vancomycin powder to evaluate the ability of local vancomycin powder to prevent deep wound infection after posterior cervical spinal fusion.

METHODS
Posterior cervical fusion spinal surgeries performed at a single institution were reviewed from January 2011 to July 2013. Each cohort's baseline characteristics, operative data, and rates of wound infection were compared. Associations between infection and vancomycin powder, with and without propensity score adjustment for risk factors, were determined using logistic regression.

RESULTS
A total of 289 patients (174 untreated and 115 treated with vancomycin powder) were included in the study. The cohorts were similar in terms of baseline and operative variables. No significant change in deep wound infection rate was seen between the control group (6.9%) and intervention group (5.2%, p = 0.563). Logistic regression, with and without propensity score adjustment, demonstrated that the use of vancomycin powder did not impact the development of surgical site infection (OR 0.743 [95% CI 0.270–2.04], p = 0.564) and (OR 0.583 [95% CI 0.198–1.718], p = 0.328), respectively.

CONCLUSIONS
Within the context of an ongoing debate on the effectiveness of locally administered vancomycin powder, the authors found no significant difference in the incidence of deep wound infection rates after posterior cervical fusion surgery with routine use of locally applied vancomycin powder. Future prospective randomized series are needed to corroborate these results.

Authors: Jalota L. , Aryal M. R. , Mahmood M. , Wasser T. , Donato A. 
Published: November 2014

SummaryObjective: To determine comfort when using the Electronic Health Record (EHR) and increase in documentation efficiency after an educational intervention for physicians to improve their transition to a new EHR.Methods: This study was a single-center randomized, parallel, non-blinded controlled trial of real-time, focused educational interventions by physician peers in addition to usual training in the intervention arm compared with usual training in the control arm. Participants were 44 internal medicine physi cians and residents stratified to groups using a survey of comfort with electronic media during rollout of a system-wide EHR and order entry system. Outcomes were median time to complete a progress note, notes completed after shift, and comfort with EHR at 20 and 40 shifts.Results: In the intervention group, 73 education sessions averaging 14.4 (SD: 7.7) minutes were completed with intervention group participants, who received an average of 3.47 (SD: 2.1) interventions. Intervention group participants decreased their time to complete a progress note more quickly than controls over 30 shifts (p < 0.001) and recorded significantly fewer progress notes after scheduled duty hours (77 versus 292, p < 0.001). Comfort with EHRs increased significantly in both groups from baseline but did not differ significantly by group. Intervention group participants felt that the intervention was more helpful than their standard training (3.47 versus 1.95 on 4-point scale).Conclusion: Physicians teaching physicians during clinical work improved physician efficiency but not comfort with EHRs. More study is needed to determine best methods to assist those most challenged with new EHR rollouts.
From Bench to Bed: Bridging from Informatics Theory to Practice
Authors: Haux R. , Lehmann C. U. 
Published: November 2014

SummaryBackground: In 2009, the journal Applied Clinical Informatics (ACI) commenced publication. Focused on applications in clinical informatics, ACI was intended to be a companion journal to Methods of Information in Medicine (MIM). Both journals are official journals of IMIA, the International Medical Informatics Association.Objectives: To explore, after five years, which congruencies and interdependencies exist in publications of these journals and to determine if gaps exist. To achieve this goal, major topics discussed in ACI and in MIM had to be analysed. Finally, we wanted to explore, whether the intention of publishing these companion journals to provide an information bridge from informatics theory to informatics practice and from practice to theory could be supported by this model. In this manuscript we will report on congruencies and interdependencies from practise to theory and on major topis in ACI. Further results will be reported in a second paper.Methods: Retrospective, prolective observational study on recent publications of ACI and MIM. All publications of the years 2012 and 2013 from these journals were indexed and analysed.Results: Hundred and ninety-six publications have been analysed (87 ACI, 109 MIM). In ACI publications addressed care coordination, shared decision support, and provider communication in its importance for complex patient care and safety and quality. Other major themes included improving clinical documentation quality and efficiency, effectiveness of clinical decision support and alerts, implementation of health information technology systems including discussion of failures and succeses. An emerging topic in the years analyzed was a focus on health information technology to predict and prevent hospital admissions and managing population health including the application of mobile health technology. Congruencies between journals could be found in themes, but with different focus in its contents. Interdependencies from practise to theory found in these publications, were only limited.Conclusions: Bridging from informatics theory to practise and vice versa remains a major component of successful research and practise as well as a major challenge.
One-Step Transepithelial Photorefractive Keratectomy With Mitomycin C as an Early Treatment for LASIK Flap Buttonhole Formation
Authors: Abdulaal Marwan R. , Wehbe Hanine A. , Awwad Shady T. 
Published: November 2014

PURPOSE:
To assess the efficacy and safety of early one-step transepithelial photorefractive keratectomy (PRK) with mitomycin C as treatment for buttonhole formation during LASIK.

METHODS:
Eight patients who developed a buttonhole during LASIK with mechanical or femtosecond flap creation underwent one-step transepithelial PRK a few days after the formation of the buttonhole. The re-treatment procedure was performed after complete epithelial healing and smooth epithelial fluorescein profile were ensured. Postoperative manifest refraction, uncorrected and corrected distance visual acuity, and haze formation were assessed during 6 months of follow-up.

RESULTS:
Mean duration of the re-treatment procedure after buttonhole formation was 5 days (range: 4 to 7 days). Mean manifest refractive spherical equivalent and cylinder refraction were −0.05 ± 0.18 and −0.18 ± 0.22 diopters, respectively, at 6 months postoperatively. Uncorrected distance visual acuity was 20/20 in all patients after 3 months of follow-up. No haze formation was detected.

CONCLUSIONS:
Early one-step transepithelial PRK with mitomycin C seems to be a safe and effective treatment for LASIK buttonhole complication.

Soil water retention curves for the major soil types of the Kruger National Park
Authors: Buitenwerf Robert , Kulmatiski Andrew , Higgins Steven I. 
Published: November 2014

Soil water potential is crucial to plant transpiration and thus to carbon cycling and biosphere–atmosphere interactions, yet it is difficult to measure in the field. Volumetric and gravimetric water contents are easy and cheap to measure in the field, but can be a poor proxy of plant-available water. Soil water content can be transformed to water potential using soil moisture retention curves. We provide empirically derived soil moisture retention curves for seven soil types in the Kruger National Park, South Africa. Site-specific curves produced excellent estimates of soil water potential from soil water content values. Curves from soils derived from the same geological substrate were similar, potentially allowing for the use of one curve for basalt soils and another for granite soils. It is anticipated that this dataset will help hydrologists and ecophysiologists understand water dynamics, carbon cycling and biosphere–atmosphere interactions under current and changing climatic conditions in the region.
Comprehension and compliance with the discharge advice and quality of life at home among the postoperative neurosurgery patients discharged from PGIMER, Chandigarh, India
Authors: Kumar Vishal , Singh Amarjeet , Tewari Manoj , Kaur Sukhpal 
Published: November 2014

Problem Statement: Neurosurgical patients require special care not only in the hospital but also after their discharge from the hospital. Comprehension and compliance to the instructions given by the doctors/nurses at the time of discharge is important in home care of these patients. Many such patients suffer from various co-morbidities. Variable periods of convalescence affect health-related quality of life in these patients.
Purpose of the Study:
To determine the degree of compliance of neurosurgery patients and their family caregivers with the discharge advice given by the consultantsTo evaluate the quality of life of these patientsTo know the problems faced by these patients at home.
Materials and Methods: This cross-sectional interview-based descriptive study was conducted in 2010 in Chandigarh. These patients were visited at their home. A scale was evolved to evaluate comprehension and compliance to the advice given at the time of discharge, according to the criteria developed by Clark et al. Lawton Brody instrumental activity of daily life and Spitzer quality of life index were used to assess patients' quality of life after the operation. Verbatim responses were recorded for the purpose of qualitative research.
Results: Overall, 58 patients and their caregivers were interviewed at home. Mean age of the patients was 38.9 years. Out of 37 patients, 35 showed good comprehension and 33 patients had a good compliance with the instructions given for medication. The condition of 74.1% patients improved after the operation. Depression was reported in 31% of the patients. Many (36.2%) patients had to quit their job due to the disease. Almost half (47.4%) of the patients were independent in daily activities of their life while being evaluated on Barthel activity of daily life index.
Conclusion and Recommendations: It is in the long term that the true complexity and impact of operations become apparent. After operation, such patients are likely to have a range of physical, emotional, cognitive, behavioral, and social problems, which may result in difficulties for both patients and their family caregivers. Provision of mechanism of prioritized follow-up care to the operated bedridden neurosurgery patients should be made.
Domian Transfer as a Strategy Deployed to Portray Massive Corruption in Olusegun Obasanjo’s Open Letter to President Jonathan: A Pragmatic Survey
Authors: Aikoriogie AM , Ugwu EN 
Published: November 2014

This essay is a pragmatic analysis of Olusegun Obasanjo.s open letter, dated 2nd December 2013, to the sitting president, Goodluck Ebele Jonathan. The letter titled ¡°Before It Is Too Late¡± raises pertinent national issues bothering on massive corruption and the degenerating state of the country.s social, economic, and political make up. There have been on-going conversations in almost every facet of the country, and outside, on the content of the letter. Also there are variations of public opinion on the intent, content, and context of the epistle, many of which come from the power brokers in Nigeria. What this essay does is to examine cases of domain transfer in the text. In the process, it discovers that the writer deploys lexical items from source domains- religion, military, business world, and Cricket game, et cetera to implicitly or explicitly portray issues of corruption in the text.Key words: open letter; domain transfer; Obasanjo; Jonathan; corruption.

Authors: Usani MO , Ushie JU , Adadu PMA 
Published: November 2014

This study investigated the relationship between job satisfaction and attitude to work of staff in Cross River State College of Education, Akamkpa. The study went on to find out the relationship between job satisfaction and attitude to work due to gender of Cross River State College of Education staff. Two research questions were formulated. A questionnaire was constructed and used for data collection. To answer the research questions two hundred and ten (210) staff of the College sampled and used. A correlational design was used for the study. The data for the research questions were analysed using correlation coefficient analysis. The findings of the study showed that job satisfaction has low relationship with attitude to work. Also job satisfaction and attitude to work have low relationship as a result of male staff and moderate relationship as a result female staff. The implication of these findings is that any staff whose attitude to work has been changed should not be attributed to job satisfaction.
Vocational Education and Economic Development in Nigeria
Authors: Ekpo K , Okon A 
Published: November 2014

This paper discusses the capability of vocational education in creating jobs to reduce unemployment among the Nigerian youths which will result in sustainable economic development of Nigeria. It also defines Vocational education within the provisions of the National Policy on Education. Philosophy of Vocational Education is also defined. In African states, including Nigeria, much emphasize is not given to Vocational Education which is a major instrument for the nations rapid and sustainable development with proper planning and implementation. Vocational education is capable of creating millions of jobs for Nigerian youths. This will lead to sustainable economic development for Nigeria in particular and African continent in general. The capability of Vocational education for job creation is not doubted but constrained by several challenges among which are poor funding, lack of training personnel and facilities. In order toovercome these challenges, it is recommended that Vocational experts, government officials and the business world should work together for the purpose of job creation, poverty alleviation and sustainable economic development.
The Role of HDlive Technology in Obstetrics and Gynecology, Present and Future
Authors: Grigore Mihaela , Cojocaru Camelia , Lazar Tudor 
Published: November 2014

ABSTRACT
Imaging techniques have continually evolved during the last few decades to improve diagnosis in obstetrics and gynecology. Developed more than 15 years ago, three-dimensional (3D) ultrasound has been widely used in clinical practice during the last decade, and its use continues to grow as researchers explore innovative new applications. High definition live (HDlive) ultrasound (US) is a novel ultrasound technology that improves both 3D and four-dimensional (4D) ultrasound images. This technology can mainly be used to study normal and pathologic embryonic and fetal development. HDlive could be important to perinatal research and could provide a better understanding of the development of the early embryo and fetus. Because of the natural pictures of the fetus that it provides, HDlive could be beneficial for increasing the fetal-maternal bonding, an important factor for healthy behavior during the pregnancy. In gynecology, HDlive could be useful in providing a better image of the adnexal pathology or coronal plane of the uterus. Although its advantages need to be further explored, in our opinion, HDlive is an innovative technique and a useful tool with applications both in obstetrics and gynecology.
