Relationships between personality, emotional labor, work engagement and job satisfaction in service professions.

OBJECTIVES
Although there have been studies linking personality to selected aspects of functioning at work, Polish literature reports a shortage of detailed analyses considering, e.g., specific professional groups or certain variables. The aim of our study was to explore the links between personality traits and emotional labor, work engagement and job satisfaction among service workers.


MATERIAL AND METHODS
The study was based on a cross-sectional, self-report survey of 137 workers representing different service industries in Poland. Each participant received a demographic data sheet and a set of questionnaires: NEO Five-Factor Inventory, the Deep Acting and Surface Acting Scale, the Job Satisfaction Scale and the Utrecht Work Engagement Scale - all in their Polish versions.


RESULTS
A correlation analysis revealed numerous relationships between the examined variables. However, results of the regression analysis showed that only some personality traits were related with individual aspects of functioning at work. Neuroticism accounted for the phenomenon of faking emotions. Conscientiousness was significantly related to general work engagement, vigor and dedication. Agreeableness and neuroticism significantly predicted job satisfaction.


CONCLUSIONS
Individual personality traits account for various aspects of work functioning. Int J Occup Med Environ Health 2016;29(5):767-782.
Pediatric hospitalizations attributable to rotavirus gastroenteritis among Cambodian children: Seven years of active surveillance, 2010-2016.

BACKGROUND
Each year, approximately 1,066 Cambodian children under five years old die of diarrhea, and 51% of these deaths are due to rotavirus gastroenteritis. Quantifying childhood hospitalizations caused by severe rotavirus infections is also important in demonstrating disease burden caused by this virus. The objective of this study is to update and confirm the current burden of pediatric hospitalizations attributable to rotavirus gastroenteritis among Cambodian children using seven years of continuous active, prospective surveillance from 2010 to 2016. We also characterize the circulating rotavirus genotypic strains during this period.


METHODS
Active surveillance for rotavirus gastroenteritis was conducted from January 2010 through December 2016 at a national hospital in Phnom Penh, Cambodia. Children <60 months of age who were hospitalized for acute gastroenteritis (AGE) were consented and enrolled. Information on gender, age, clinical characteristics, and month of onset were collected. Stool specimens were collected and tested by enzyme immunoassay for the presence of rotavirus antigen, and genotyping was performed on rotavirus test-positive specimens to characterize predominant rotavirus strains during the surveillance period.


RESULTS
Of 7007 children enrolled with AGE and having specimens collected, 3473 (50%) were attributed to rotavirus gastroenteritis. The majority of rotavirus hospitalizations occurred in children younger than two years old (92%). Year-round rotavirus transmission was observed, with seasonal peaks during the cooler, dry months between November and May. Genotypic trends in rotavirus were observed over the surveillance period; the predominant rotavirus strains changed from G1P[8] (2010-2012), to G2P[4] (2013-2014), the emergence of genotype G8P[8] in 2015, and G3P[8] in 2016.


CONCLUSIONS
Rotavirus is the leading cause of severe acute gastroenteritis hospitalizations in Cambodian children under five years old, with 50% of such hospitalizations attributable to rotavirus. Over 90% of rotavirus hospitalizations occurred in children under 2 years of age. Changes in the predominant rotavirus strains occurred over time among these unvaccinated children. This information is important to understand and prioritize the current potential impacts upon child health that could be achieved through the introduction of rotavirus vaccines in Cambodia.
Intrabiliary rupture of a hepatic hydatid cyst: associated clinical factors and proper management.

HYPOTHESIS
The prediction of an intrabiliary rupture of a hepatic hydatid cyst using associated clinical factors is important for early diagnosis and proper management.


DESIGN
Case series of patients with hepatic hydatid cysts treated between January 1, 1992, and January 1, 2000, in a single institution.


SETTING
A tertiary care teaching hospital.


PATIENTS
The clinical findings in 116 patients with a hepatic hydatid cyst were reviewed. Of the 116 patients, 24 (21%) had a cyst-biliary communication: 15 (13%) had an occult rupture, and 9 (8%) had a frank rupture.


MAIN OUTCOME MEASURES
The following variables were analyzed as potential predictors of an intrabiliary rupture: age, sex, type and duration of symptoms, findings on physical examination, leukocyte count, liver function test results, serologic test results, suggestive ultrasonographic findings, ultrasonographic cyst features (type, diameter, number, and localization), and whether the cyst is primary or recurrent.


RESULTS
The independent clinical factors for the presence of an occult rupture were a history of nausea and vomiting (P = .004), alkaline phosphatase level greater than 144 U/L (P = .004), total bilirubin level greater than 0.8 mg/dL (>13.5 micromol/L) (P< .001), and cyst diameter greater than 14.5 cm (P< .001) in multivariate analysis. Multivariate analysis also showed that history of jaundice (P< .001), jaundice found on physical examination (P = .05), cyst diameter greater than 10.5 cm (P = .009), a type IV cyst (P< .001), and suggestive ultrasonographic findings (P< .001) were the independent clinical predictors for the presence of a frank intrabiliary rupture. Patients with cyst-biliary communications had increased morbidity rates (13 [54%] of 24 patients vs 13 [14%] of 92 patients; P< .001) and longer mean postoperative hospital stays (13.7 vs 9.4 days; P = .03) compared with others.


CONCLUSION
Clinical predictors should be considered for early diagnosis and proper management of intrabiliary ruptures in patients with hepatic hydatid cysts.
Factors associated with utilization of long acting and permanent contraceptive methods among married women of reproductive age in Mekelle town, Tigray region, north Ethiopia

BACKGROUND
Ethiopia is the second most populous country in Sub-Saharan Africa. Total Fertility Rate of Ethiopia is 5.4 children per women, population growth rate is estimated to be 2.7% per year and contraceptive prevalence rate is only 15% while the unmet need for family planning is 34%. Overall awareness of Family Planning methods is high, at 87%. The prevalence of long acting and permanent contraceptive methods (LAPMs) in Tigray region was very low which accounts for 0.1% for implants and no users for intra-uterine contraceptive device (IUCD) and female sterilization. Moreover almost all modern contraceptive use in Ethiopia is dependent on short acting contraceptive methods. The objective of this study was to assess factors associated with utilization of long acting and permanent contraceptive methods (LAPM) among married women of reproductive age group in Mekelle town.


METHODS
A cross sectional community based survey was conducted from March 9-20, 2011. Multistage sample technique was used to select the participants for the quantitative methods whereas purposive sampling was used for the qualitative part of the study. Binary descriptive statistics and multiple variable regressions were done.


RESULTS
The study consisted of quantitative and qualitative data. From the quantitative part of the study the response rate of the study was 95.6%. Of the qualitative part two FGDs were conducted for each married women and married men. 64% of the married women heard about LAPMs. More than half (53.6%) of the married women had negative attitude towards practicing of LAPMs. The overall prevalence of LAPMs use was 12.3% however; there were no users for female or male sterilization. The main reason cited by the majority of the married women for not using LAPMs was using another method of contraception 360 (93.3%). Mothers who had high knowledge were 8 times more likely to use LAPMs as compared with those who had low knowledge (AOR = 7.9, 95% CI of (3.1, 18.3). Mothers who had two or more pregnancies were 3 times more likely to use LAPM as compared with those who had one pregnancy (AOR = 2.7, 95% CI of (1.4, 5.1).


CONCLUSION
A significant amount of the participants had low knowledge on permanent contraceptive particularly vasectomy. More than half (53.6%) of married women had negative attitude towards practicing of LAMPs. Few of married women use female sterilization and none use of female sterilization and or vasectomy. Positive knowledge of LAMPs, women who had two and above pregnancies and women who do not want to have additional child were significantly associated. Information education communication should focus on alleviating factors hinder from practicing of LAPMs.
Salt bridges: geometrically specific, designable interactions.

Salt bridges occur frequently in proteins, providing conformational specificity and contributing to molecular recognition and catalysis. We present a comprehensive analysis of these interactions in protein structures by surveying a large database of protein structures. Salt bridges between Asp or Glu and His, Arg, or Lys display extremely well-defined geometric preferences. Several previously observed preferences are confirmed, and others that were previously unrecognized are discovered. Salt bridges are explored for their preferences for different separations in sequence and in space, geometric preferences within proteins and at protein-protein interfaces, co-operativity in networked salt bridges, inclusion within metal-binding sites, preference for acidic electrons, apparent conformational side chain entropy reduction on formation, and degree of burial. Salt bridges occur far more frequently between residues at close than distant sequence separations, but, at close distances, there remain strong preferences for salt bridges at specific separations. Specific types of complex salt bridges, involving three or more members, are also discovered. As we observe a strong relationship between the propensity to form a salt bridge and the placement of salt-bridging residues in protein sequences, we discuss the role that salt bridges might play in kinetically influencing protein folding and thermodynamically stabilizing the native conformation. We also develop a quantitative method to select appropriate crystal structure resolution and B-factor cutoffs. Detailed knowledge of these geometric and sequence dependences should aid de novo design and prediction algorithms.
Wavelet transform and simplicity based heart murmur segmentation

This paper is aimed at the identification of the boundaries of murmur present in heart sound. Heart murmurs provide crucial diagnosis information for several heart diseases such as natural or prosthetic valve dysfunction and heart failure. In order to find the valuable information about abnormal heart behavior, segmentation of the heart murmurs has to be performed. In this work we solve this problem using the wavelet decomposition- simplicity filter. In this algorithm, simplicity of the wavelet decomposed heart sound signal is measured and adaptively thresholded in order to discriminate S1/S2 sounds from murmurs. The method has been tested with stenosis and regurgitation (aortic, mitral, pulmonary, tricuspid) heart sounds and 89.10% sensitivity and 95.50 % specificity have been achieved.

In this paper, we proposed an intuitive method of combining the information from multiple frames for the inference of room layout and showed the potentials of this method.
Mothers' reports of postpartum pain associated with vaginal and cesarean deliveries: results of a national survey.

BACKGROUND
As cesarean rates increase worldwide, a debate has arisen over the relationship of method of delivery to maternal postpartum physical health. This study examines mothers' reports of their postpartum experiences with pain stratified by method of delivery.


METHODS
Listening to Mothers II was a survey of a total of 1,573 (200 telephone and 1,373 online) mothers aged 18 to 45 years, who had a singleton, hospital birth in 2005. They were interviewed by the survey research firm, Harris Interactive, in early 2006. Online respondents were drawn from an existing Harris panel. Telephone respondents were identified through a national telephone listing of new mothers. Results were weighted to reflect a United States national birthing population. Mothers were asked if they experienced any of eight postpartum conditions and the extent and the duration of the problem. Responses were compared by method of delivery.


RESULTS
The most frequently cited postpartum difficulty was among mothers with a cesarean section, 79 percent of whom reported experiencing pain at the incision in the first 2 months after birth, with 33 percent describing it as a major problem and 18 percent reporting persistence of the pain into the sixth month postpartum. Mothers with planned cesareans without labor were as likely as those with cesareans with labor to report problems with postpartum pain. Almost half (48%) of mothers with vaginal births (68% among those with instrumental delivery, 63% with episiotomy, 43% spontaneous vaginal birth with no episiotomy) reported experiencing a painful perineum, with 2 percent reporting the pain persisting for at least 6 months.


CONCLUSIONS
Substantial proportions of mothers reported problems with postpartum pain. Women experiencing a cesarean section or an assisted vaginal delivery were most likely to report that the pain persisted for an extended period.
OPERATING ROOM PLANNING AND SCHEDULING PROBLEMS: A CLASSIFICATION SCHEME

The increasing interest in the domain of operating room planning and scheduling leads to a proliferation of problem types. The statement and the scope of the particular problems, however, are often unclear. In this paper, we report on a scheme to classify operating room planning and scheduling problems using multiple fields. Each field describes a specific set of characteristics of the particular problem by means of parameters, elements and optional further specifications. We also elaborate on the use of delimiters to separate the entries in the classification notation. Next to the formulation of the scheme, we examine its applicability on a range of problems that are encountered in recent literature. With the development of the classification scheme, we hope to structure and to clarify forthcoming research in this domain.
Cannabis Vaporizer Combines Efficient Delivery of THC with Effective Suppression of Pyrolytic Compounds

Cannabis vaporization is a technology designed to deliver inhaled cannabinoids while avoiding the respiratory hazards of smoking by heating cannabis to a temperature where therapeutically active cannabinoid vapors are produced, but below the point of combustion where noxious pyrolytic byproducts are formed. This study was designed to evaluate the efficacy of an herbal vaporizer known as the Volcano®, produced by Storz & Bickel GmbH&Co. KG, Tuttlingen, Germany (http://www.storz-bickel.com). Three 200 mg samples of standard NIDA cannabis were vaporized at temperatures of 155°-218°C. For comparison, smoke from combusted samples was also tested. The study consisted of two phases: (1) a quantitative analysis of the solid phase of the vapor using HPLC-DAD-MS (High Performance LiqDale Gieringer is affiliated with California NORML, 2215-R Market Street #278, San Francisco, CA 94114.

The HPLC analysis of the vapor found that the Volcano delivered 36%-61% of the THC in the sample, a delivery efficiency that compares favorably to that of marijuana cigarettes. The GC/MS analysis showed that the gas phase of the vapor consisted overwhelmingly of cannabinoids, with trace amounts of three other compounds. In contrast, over 111 compounds were identified in the combusted smoke, including several known PAHs. The results indicate that vaporization can deliver therapeutic doses of cannabinoids with a drastic reduction in pyrolytic smoke compounds. Vaporization therefore appears to be an attractive alternative to smoked marijuana for future medical cannabis studies.

Translating the Dietary Approaches to Stop Hypertension (DASH) Diet for Use in Underresourced, Urban African American Communities, 2010

INTRODUCTION
Randomized trials have demonstrated the effectiveness of the Dietary Approaches to Stop Hypertension (DASH) program for lowering blood pressure; however, program participation has been limited in some populations. The objective of this pilot study was to test the feasibility of using a culturally modified version of DASH among African Americans in an underresourced community.


METHODS
This randomized controlled pilot study recruited African Americans in 2 North Carolina neighborhoods who had high blood pressure and used fewer than 3 antihypertension medications. We offered 2 individual and 9 group DASH sessions to intervention participants and 1 individual session and printed DASH educational materials to control participants. We collected data at baseline (March 2010) and 12 weeks (June 2010).


RESULTS
Of 152 potential participants, 25 were randomly assigned to either the intervention (n = 14) or the control (n = 11) group; 22 were women, and 21 were educated beyond high school. At baseline, mean blood pressure was 130/78 mm Hg; 19 participants used antihypertension medications, and mean body mass index was 35.9 kg/m(2). Intervention participants attended 7 of 9 group sessions on average. After 12 weeks, we observed significant increases in fruit and vegetable consumption and increases in participants' confidence in their ability to reduce salt and fat consumption and eat healthier snacks in intervention compared with control participants. We found no significant decreases in blood pressure.


CONCLUSION
Implementation of a culturally modified, community-based DASH intervention was feasible in our small sample of African Americans, which included people being treated for high blood pressure. Future studies should evaluate the long-term effect of this program in a larger sample.
The Erector Spinae Plane Block.

Copyright © 2017 American Society of Region Attempting to understand the site of action of the block raises the question as towhether the ESP block is in fact a paravertebral block by another name. This seems the most likely explanation for the pattern of sensory block obtained, and there is a clue to this being so in the cadaver dye studies described in the article. It is an interesting question since if ESP block turns out to be a paravertebral block, then Forero et al have discovered a much simpler and safer technique for performing the block. Furthermore, it is possible that this block has “inadvertently” been used many times in the past during performance of landmark-based paravertebral blocks. On the other hand, if it is a new fascial plane blockwith a different mechanism of action than a classical paravertebral block, it also represents a significant advance in patient safety. The ESP block should be associated with a much lower risk of nerve damage and pneumothorax, and it is probably relatively safe in patients with coagulation disorders. Applications in anesthesia and pain medicine are likely to be many, and the technique should be subjected to further scientific and clinical investigation. We have already had some success with the technique in a patient withmultiple acute rib fractures but have yet to determine whether ESP block provides sufficient
Model of Factors Influences on Electronic Commerce Adoption and Diffusion in Small-& Medium-sized Enterprises

Since the emergence of the Internet, it has allowed Smalland Medium-sized Enterprises (SMEs) to compete effectively and efficiently in both domestic and international market (Poon and Swatman, 1999). However, the resistance and mismanagement of SMEs to adopt Electronic Commerce proficiently often impede such leverage. This study aims to develop a model of Electronic Commerce adoption to assist those SMEs that are considering or are currently conducting their business using the Internet. Building on an examination of current technology diffusion literature, a model of EC adoption has been developed. It investigates factors that potentially influence the adoption of Electronic Commerce, followed by an examination in the diffusion process that SMEs experience while integrating EC into their business systems.
Newton-like method with diagonal correction for distributed optimization

We consider distributed optimization problems where networked nodes cooperatively minimize the sum of their locally known convex costs. A popular class of methods to solve these problems are the distributed gradient methods, which are attractive due to their inexpensive iterations, but have a drawback of slow convergence rates. This motivates the incorporation of second-order information in the distributed methods, but this task is challenging: although the Hessians which arise in the algorithm design respect the sparsity of the network, their inverses are dense, hence rendering distributed implementations difficult. We overcome this challenge and propose a class of distributed Newton-like methods, which we refer to as Distributed Quasi Newton (DQN). The DQN family approximates the Hessian inverse by: 1) splitting the Hessian into its diagonal and off-diagonal part, 2) inverting the diagonal part, and 3) approximating the inverse of the off-diagonal part through a weighted linear function. The approximation is parameterized by the tuning variables which correspond to different splittings of the Hessian and by different weightings of the off-diagonal Hessian part. Specific choices of the tuning variables give rise to different variants of the proposed general DQN method – dubbed DQN-0, DQN-1 and DQN-2 – which mutually trade-off communication and computational costs for convergence. Simulations illustrate that the proposed DQN methods compare favorably with existing alternatives.
