Prioritizacija i procjena ključa sigurnosti pokazatelja uspjeha u automobilskoj industriji

The performance of any management system needs to be monitored with adequate and proper indicators. This study aimed to identify, set priorities and assess key indicators for implementing an effective performance evaluation system. This descriptive-analytical study was carried out in three phase. In first phase, a semi-structured interview as well as a review of the company\u27s documentation and studies carried out, then a set of key indicators were collected and selected. The validity of the indicators were determined by experts (N = 11) and indicators were prioritized using Analytic Hierarchy Process (AHP) according to SMART (Specific, Measurable, Achievable, Relevant, and Time- bound) criteria. Following the study framework, a primary set of 60 Key Performance Indicators (KPIs) were collected. The results of the validity assessment showed 23 indicators had acceptable validity. The results of examining the relationships between the indicators showed that the percentage of corrected non- compliance and the number of risk assessments had a significant relationships with the total number of work-related lost time injuries as a lagging indicator. According to the results, the four the most important key performance indicators to assess the safety performance in the automotive industry were as follows: the number of risk assessments conducted, the percentage of corrected non- compliance, the percentage of safety educational programs implemented for workers, and Frequency Severity Index (FSI) index.Učinkovitost bilo kojeg sustava upravljanja treba pratiti odgovarajućim i ispravnim pokazateljima. Cilj ove studije bio je identificirati, odrediti prioritete i procijeniti ključne pokazatelje za primjenu učinkovitog sustava vrednovanja učinka. Ovo opisno-analitičko istraživanje provedeno je u tri faze.

Effect of different dosages of nitroglycerin infusion on arterial blood gas tensions in patients undergoing on- pump coronary artery bypass graft surgery

Background: On-pump coronary artery bypass graft (CABG) surgery impairs gas exchange in the early postoperative period. The main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump CABG surgery receiving different dose of intravenous nitroglycerin (NTG). Materials and Methods: sixty-seven consecutive patients undergoing elective on-pump CABG randomly enrolled into three groups receiving NTG 50 μg/min (Group N1, n =67), 100 μg/min (Group N2, n = 67), and 150 μg/min (Group N3, n = 67). Arterial blood gas (ABG) tensions were evaluated just before induction of anesthesia, during anesthesia, at the end of warming up period, and 6 h after admission to the intensive care unit. Results: Pao2 and PH had the highest value during surgery in Group N1, Group N2, and Group N3. No significant difference was noted in mean values of Pao2 and PH during surgery between three groups (P > 0.05). There was no significant difference in HCO 3 values in different time intervals among three groups (P > 0.05). Conclusion: our results showed that infusing three different dosage of NTG (50, 100, and 150 μg/min) had no significant effect on ABG tensions in patients underwent on-pump CABG surgery

A review of the etiology, diagnosis and management of halitosis

Halitosis generally refers to the unpleasant odor of breath irrespective of its origin. Oral malodour could result in diverse problems in daily life such as social embarrassment and can adversely affect individuals' social interactions. Though many oral and non-oral sources could give rise to halitosis, it was mainly associated with oral cavity conditions and volatile sulfur compounds -produced by microbial activity- were the main elements of oral malodor. Objective measurement was the first step in assessment to determine presence of malodour. Then, taken a complete history including diet and habit history and performing a comprehensive physical examination contribute to the primary two steps for evaluating a patient complaining. The oral malodor management was mainly achieved by determining and eliminating the etiology of the condition. A major step in this regard was improving the oral health by means of establishing appropriate oral hygiene measures and controlling tongue flora by brushing or scraping and also, use of antiseptics as adjuvant therapy. Current article was systematic reviews the literature on prevalence, classification, diagnosis and treatment of halitosis. © 2015, Iranian Association of Gastroenterology and Hepatology.

The effect of acute caffeine supplementation on C-reactive protein and interleukin-6 responses following super-slow resistance training in trained men

Background and Aims: According to limited and inconsistent results about the effect of acute supplementation of Metyl-Xantine on inflammatory responses following training, this study was to determine the effect of acute caffeine consumption on C-reactive protein and interleukin-6 responses following one session of super-slow resistance training. Material and Method: In order to achieve the purpose of the study, 16 trained males (mean age, 24 ± 0/75 years, and fat percentage 10/3 ± 0/61 and BMI 23 /5 ± 0/49 kg /m2 ) participated in a quasi-experimental design and were randomly assigned in two homogenous groups (n=8): (1) super-slow resistance group with placebo (10 reps, %40 1RM,1 times, total time 120 seconds) and (2) super-slow resistance group with caffeine (6mg/kg). Blood samples were collected before and 24 hours after training to determine C-reactive protein and interleukin-6. Data were analyzed by independent t-test at the significant level (P≤0/05). Findings: The results suggest that super-slow resistance training significantly increased C-reactive protein and IL-6(P≤0/05). The increase in the supplement group was significantly lower. Conclusion: we conclude that super-slow resistance training causes low-grade inflammation increased IL-6 concentrations ( supplement group: from 23/57 to 24/93 pg/ml, placebo group: from 22/48 to 29/08 pg/ml) and C-reactive protein (supplement group: from 0/72 to 0/82 mg/l, placebo group: from 0/69 to 1/2 mg/l ) and acute caffeine consumption can improve inflammatory responses in resistance training male. So we suggest male bodybuilder athletes to acute caffeine supplementation before and during their resistance training session to reduce the inflammatory responses following resistance training

Cavity solitons synchronization

By modulating two cavity solitons (CSs) locally, in a driven vertical cavity surface emitting laser above threshold, we forced them to oscillate sinusoidally in time. It is illustrated that the amplitude of modulation of two CSs plays an important role in their synchronization. We show that the oscillations of two CSs can be synchronized only when the interaction of them is highly nonsymmetrical and the difference of the modulation frequencies is at most of the order of 1 GHz.

Peripheral neuropathy in ulcerative colitis: A case report

Inflammatory bowel diseases (IBD) were systemic disorders involving many organ systems. Besides intestinal manifestations, extra intestinal manifestations (EIMs) including neurologic complications have been reported among 6-40 of IBD patients. Ulcerative colitis (UC) was a subtype of IBD only affecting the colonic mucosa and sub mucosa. Although the EIMs of UC could affect any organ system, central and peripheral neurological manifestations were relatively rare. Here, we described a case of UC and concurrent primary sclerosing cholangitis (PSC) who complained about paresthesia and weakness of his upper and lower limbs for the past two months. Through physical examination revealed decreased muscle tone in his legs and arms. Electrophysiological studies were compatible with the diagnosis of chronic mixed polyneuropathy which improved after administration of intravenous immunoglobulin (IVIG) and the patient was discharged in good general condition. Although both immunologic and non-immunologic mechanisms we considered to play a role in development of neuropathies, further investigations were still required to accurately understand the underlying mechanism. © 2015, Iranian Association of Gastroenterology and Hepatology.

A rare presentation of primary hepatic lymphoma: A case report

Primary hepatic lymphoma (PHL) was a rare malignancy usually presenting with abdominal pain, malaise, Hepatomegaly, B-symptoms, fatigue, nausea, vomiting and jaundice. It mostly involves liver without any palpable lymphadenopathy and leukemia in peripheral blood smear. On July 22, 2014, a 64 year old man presented with abdominal pain localizing in Right upper quadrant and fullness from 2 years ago without any wight loss or constitutional symptoms. His physical examination revealed no mass or lymphadenopathy and lab data showed rise in Alkaline phosphatase(ALP) and Gamma-glutamyl transferase(gamma-GT). Abdominal computed tomography(CT) scan with contrast showed a calcified lesion in the left lobe of liver and illdefined hypodense area in medial segment of the left lobe of liver adjacent to gallbladder associated with mild central intra hepatic bile ducts dilation showing more enhancement in delay phase suggested peripheral cholangiocarcinoma. Finally surgical core needle biopsy of the liver confirmed malignant lymphoma of B cell type and patient was referred to oncologist for chemotherapy. His chemotherapy regimen consisted of rituximab 600 milligram (mg), endoxan 1250 mg, adriamycin 80 mg, vincristine 2 mg, prednisolone 100 mg (during five days) for 6 courses. After 5 months chemotherapy, on December 22, 2014 a follow up CT scan with IV and oral contrast was done. There was no evidence of previous mass lesion in the liver. In the follow up on May 9, 2015, he had no specific symptoms and all of his lab data were in normal range

Interaction of cavity solitons on an unstable background

The interaction of two cavity solitons in a driven semiconductor laser above lasing threshold is investigated. We focus on the case in which the background field of the solitons is turbulent because the laser is below the injection locking point. We show that the solitons move spontaneously and either reach some equilibrium distance or merge. Different behaviors are found depending on how far from the injection locking point the laser is. The laser is modeled by a set of effective Maxwell-Bloch equations which include an equation for the macroscopic polarization that mimics the complex susceptibility of the semiconductor. In that way we avoid the emergence of an unphysical behavior of the background which instead appears when the polarization is adiabatically eliminated, which amounts to assuming infinite gain linewidth. The simulations are slow because the time scales of the different dynamical variables differ by four orders of magnitude. Yet, we show that the results of the complete set of equations can be accurately reproduced with a reduced set of equations where the polarization is adiabatically eliminated but a diffusion term is included in Maxwell equation, which accounts for the finiteness of the gain linewidth

Motor Deficits of Girls with Down Syndrome in Comparing with Girls with Intellectual Disability in the School Ages Children

Objective: Motor function in children with Down syndrome is similar to mentally retarded children. But the movements are slower and have lower quality. The purpose of this study was to identify weaknesses in motor function in children with Down syndrome, by using Bruininks Oseretsky Test of Motor Proficiency (BOTMP). Materials & Methods: In this cross-sectional study, thirty six children with intellectual disability, 18 girls with Down syndrome and 18 girls without Down syndrome, with chronological aged 8-13 years were investigated. The subjects of Down syndrome were selected by available sampling. The subjects of intellectual disability were selected by simple random sampling. Two groups of participants were matched for chronological age and IQ level. The measurement was BOTMP. Statistical analysis was performed using the Mann-Whitney U rank sum test and t-test. Results: The children with Down syndrome scored significantly lower than the mentally retarded children in the areas of gross motor skill composite (P<0.014) balance (P<0.029), response time (P<0.034) and visual motor control (P<0.048), but the fine motor and overlay motor skill composite, and subtests of bilateral coordination, strength, upper limb coordination scores were no significantly different between two groups. Conclusion: Motor rehabilitation is appropriate for children with intellectual disability, especially for children with Down syndrome, in throughout their adolescence.
