Microscopic Analysis of Pottery Fragments from the Corded Ware Culture at Sites 11, 15 and 20 in Święte, Jarosław District

Abstract For microscopic examination, 22 pottery fragments from sites 11, 15 and 20 in Święte, Jarosław District were selected. The pottery types included beakers (N=19) and amphorae (N=3). The goal of the petrographic analysis was to identify mineralogical composition of ceramic fabric, sources of raw materials, and intentional additives to the clay. The analysis yielded data that helped determine ceramic fabrics types and preparation methods, as well as pottery firing conditions and approximate firing temperature. In all samples analysed, ceramic fabrics were prepared in a similar way, using heavy clay poor in muscovite, with grog deliberately added. Crystalline material present in some of the samples is most likely a natural component of raw materials used in the production process. No sand is added to the clay. No other method for preparing pastes was identified for the amphorae type. Previous observations on amphorae firing are confirmed: amphorae are fired in oxidizing conditions. The ceramic fabrics of two vessels have a deliberate admixture of bones in addition to grog and argillaceous rock intraclasts. Vessels decorated with cord impressions and vessels with herringbone or other incised patterns are more often made from paste type A (inclusion and grog) and paste type B (grog), respectively.
Analysis of occupational accidents in the construction industry with regards to selected time parameters

Abstract The construction industry is characterized by a large variety and variability of implementation conditions. Construction works are carried out throughout the whole calendar year under varying atmospheric conditions, both during the day and also during the evening and night. Construction workers also often work overtime that exceeds the eight-hour working day. Work in such conditions creates a particularly high threat to the health and life of working people. In the issues of work safety the most important is worker, who in the accident process has a triple role: the decision maker, the perpetrator of an accident and the victim. The purpose of this article is to examine whether there is a dependence between the number of occupational accidents in the construction industry and time parameters such as: the time of an accident, the day of the week and the month in which an accident occurred. The article also attempts to determine the dependence between the age of the injured person, work experience and the number of hours worked by the injured person from the time of starting work to the moment of the accident.
Le théorème de von Staudt en géométrie projective quaternionienne.

Dans une geometrie projective ä corps fondamental quelconque (commutatif ou non), de caracteristique 2), on definit la projectivite, au sens de von Staudt, entre deux figures de rang un, comme correspondance biunivoque qui ä toute division harmonique laisse correspondre une autre division harmonique, Si le corps fondamental K est commutatif, on demontre un theoreme) qui resulte comme generalisation du thooreme de von Staudt pour la geomotrie projective reelle et dont l'enonce peut se ramener ä celui-ci: Dans toute projectivite entre deux ponctuelles d'une meme droite ayant trois points doubles, si prend ces points comme points de repere (point-zero, -unite et -de Vinfini), la relation reliant les points homologues etablit un automorphisme de K. Et redproquement, un automorphisme quelconque de K definit entre deux ponctuelles d'une meme droite, rapportees aux memes points de repere, une projectivite dans laquelle sont doubles ces points*). Si K n'est pas commutatif, la possible extension du theoröme de von Staudt n'a pas encore ete envisagee. On peut montrer (nous le faisons dans cette Note) dans le cas d'un corps quelconque, et d'une maniere tout ä fait analogue ä celle dont on fait usage quand le corps est commutatif pour prouver l'existence de automorphisme, que dans toute projectivite satisfaisant aux conditions de l'ononce du thoorome de von Staudt, la relation x = (x)' entre points homologues donne lieu ä une transformation biunivoque du corps K sur lui-meme dans laquelle on a (I) (x + y) = x' + y, (II) (xy)'+ (yx)'^x'y'+ y'x'. Nous proposons d'appeller semi-automorphisme de K une transformation de ce type. On peut enoncer alors le resultat indiquo plus haut sous la forme suivante: Pour le cas d'un corps quelconque, un projectivite entre deux ponctuelles d'une meme droite, ayant doubles les points de rep&re, definit un somi-automorphisme du corps. Ainsi nous avons obtenu une extension de la premiore partie du thooröme de von Staudt au cas d'un corps non-commutatif. La question de la gonoralisation de la reci-

Or il existe deux methodes pour traiter cette matiere: Tone d'elles, la methode syntheiique, reputee insuffisante, a ete de nos jours presque entierement negligee; on ne s'est guere occupe que de Fautre, de la methode analytique, que croyait preferable sous tous les rapports.

Can Macroeconomic Variables Explain Long Term Stock Market Movements? A Comparison of the US and Japan

Within the framework of a standard discounted value model we examine whether a number of macroeconomic variables influence stock prices in the US and Japan. A cointegration analysis is applied in order to model the long term relationship between industrial production, the consumer price index, money supply, long term interest rates and stock prices in the US and Japan. For the US we find the data are consistent with a single cointegrating vector, where stock prices are positively related to industrial production and negatively related to both the consumer price index and a long term interest rate. We also find an insignificant (although positive) relationship between US stock prices and the money supply. However, for the Japanese data we find two cointegrating vectors. We find for one vector that stock prices are influenced positively by industrial production and negatively by the money supply. For the second cointegrating vector we find industrial production to be negatively influenced by the consumer price index and a long term interest rate. These contrasting results may be due to the slump in the Japanese economy during the 1990s and consequent liquidity trap.
Mémoire sur les inégalités séculaires des grands axes des orbites des planètes.

Jues actions mutuelles des planstes fönt varier les eloments de leur mouvement elliptique qui demeureraient constants, si elles n'otaient soumises qu'ä Taction du Soleil. Les variations de ces oloments se partagent en megaUtes periodiques et en inegalites seculaires. Ces dernieres, pendant plusieurs siecles, peuvent 6tre eonsidoroes comme proportionnelles au temps et modifient peu ä peu les figures des orbites et leurs positions dans Tespace. Mais, parmi ces inogalitos seculaires, celles dont la connaissanoe exaete Interesse le plus les astronomes, sont eelles du grand axe; car les inegalitos du moyen mouvement de la plannte dependent de celles du grand axe d'apräs la troisi^me loi de Kepler. Laplace domontra d'abord que les grands axes ne sont soumis ä aucune Variation soculaire, si neglige les termes du troisiome ordre par rapport aux excentricitos et aux inclinaisons suppos^es tres-petites. Lagrange prouva ensuite que cette proposition a lieu, quelque loin que pousse Tapproximation, et par consoquent aussi pour des excentricitos et des inclinaisons arbitraires.

Genetics of developmental dysplasia of the hip: Recent progress and future perspectives

Developmental dysplasia of the hip (DDH) is the most common congenital orthopedic disorder in infants. DDH is a heterogeneous disorder, and the exact pathophysiology is incompletely understood; however, several environmental as well as genetic factors have been identified as an underlying player in its pathogenesis. Involvement of genetic factors in the pathogenesis is evident from the fact that DDH occurrence has been observed in families with multiple affected individuals. Here, we reviewed the current literature on DDH, specifically concentrating on the genetic aspects of isolated (nonsyndromic) form of DDH. It is observed that genetic association studies, as well as linkage study designs, have been used to identify the extent of involvement of genetic factors in DDH pathogenesis. Variants in genes involved in joint development and chondrogenesis including HOXD9, ASPN, HOXB9, TGF-Beta 1, PAPPA2, DKK1, and GDF5 genes have been identified as associated with DDH through genetic association studies. Moreover, mutations in CX3CR1 and TENM3 have been identified using linkage analysis and exome sequencing. Although various approaches including association studies, linkage analysis, and targeted sequencing have been used to detect genetic factors underlying DDH, structural genetic variants underlying DDH have not been explored. Therefore, we propose that copy number variation analysis and interactome studies (interaction analysis using gene and protein data using molecular interaction search tools) can help in identifying new DDH-associated genes.
Frequency of hemophilia and hemostatic evaluation in persons with bleeding symptoms in Southeast, Nigeria

Background: A significant number of people living with hemophilia and other bleeding disorders are reported to be either underdiagnosed or untreated in most developing countries. Objectives: To evaluate the frequency of hemophilia and some hemostatic parameters in persons with bleeding symptoms in Southeast Nigeria. Materials and Methods: This was a cross-sectional, hospital-based pilot study of 50 persons consecutively recruited with bleeding symptoms from four tertiary hospitals in Southeast Nigeria. Full blood count was carried out using Mythic 22 semiautomated analyzer, (Orphee, Geneva, Switzerland). Prothrombin time (PT) and activated partial thromboplastin time (APTT) mixing studies and one-stage factor assays were carried out using tube tilt technique. Bleeding score was assessed using the International Society on Thrombosis and Haemostasis bleeding assessment tool. Data were analyzed using the Graphpad Prisim, version 6.0, San Diego. Results: Only 2% of the subjects had hemophilia A, whereas 68% of the subjects had thrombocytopenic bleeding. Most (32.4%) had bleeding score of four. Analysis of variance of these variables showed a significant relationship with P < 0.0001. Post hoc analysis showed significant P values for platelet count versus bleeding score (P = 0.000, 95% confidence interval [CI]: 95.74–126.4) and APTT versus bleeding score (P = 0.000, 95% CI: 44.34–74.98). Conclusion: Bleeding assessment tools are important in evaluating persons with bleeding symptoms and it may be necessary to screen for hemophilia in these cases. Larger multicenter epidemiological studies are needed to determine the prevalence of hemophilia and other bleeding disorders in our environment.
Intracranial Malignant Nerve Sheath Tumor in the Middle Cranial Fossa: A Rare Case Report with Review of Literature

Intracranial malignant nerve sheath tumors rarely arise in the central nervous system. They usually arise from the cranial nerves, though rare cases of intraparenchymal lesions have also been reported. We report a case of malignant nerve sheath tumor located in the right middle cranial fossa. Preoperatively, the lesion resembled a meningioma arising from the petrous temporal bone. The lesion was completely excised. Postoperatively, the patient developed righted-sided complete facial nerve palsy. Histopathology and immunohistochemistry revealed the lesion to be a malignant nerve sheath tumor. The development of postoperative facial nerve palsy was puzzling but could be explained if we consider the possibility of the lesion arising from the facial nerve near the geniculate ganglion. Intracranial malignant nerve sheath tumor centered over the geniculate ganglion and projecting into the middle cranial fossa is uncommon, and to the best of our knowledge, only one such case has been previously reported. We review the relevant literature, discuss the management and add to the previously reported cases of this rare condition.
Systemic Candida infection in preterm babies: Experience from a tertiary care hospital of North India

Background: Neonatal fungal infection is an important cause of late-onset sepsis with very high mortality. The incidence is progressively increasing due to a marked improvement in the survival of low-birth weight neonates. Materials and Methods: This was a 2-year observational study. Very low-birth weight (VLBW) and extremely low-birth weight (ELBW) with suspected fungal sepsis were enrolled. All suspected neonates were evaluated for possible Candida infection. Complete clinicodemographic and laboratory profile was noted from the study participants. The main outcome measure was hospital incidence, clinical profile, and the frequency of end-organ involvement. Results: During the study, 304 ELBW and VLBW neonates were screened for invasive fungal sepsis. Sixty-four neonates were found positive for invasive Candida sepsis making the incidence of 11.6%. Majority of patients developed worsening of respiratory distress and shock. Necrotizing enterocolitis (NEC) was seen in 10 patients and disseminated intravascular coagulation (DIC) in nine patients. Nearly 7.8% had cerebrospinal fluid culture positive for Candida. Renal abscess was seen in two patients. Endohpthalmitis and endocarditis each were observed in one patient. The mortality rate in our study group was 55%. Conclusion: We found 11.9% incidence of invasive fungal incidence. Majority of neonates developed worsening of respiratory distress, shock, NEC, DIC, and thrombocytopenia. End-organ damage was noticed in 14% of patients. Mortality was around 55% in our cohort.
Clinical profile and outcome of newborns admitted to a secondary-level neonatal intensive care unit in tribal region of Odisha

Introduction: Neonatal deaths constitute major proportion of under-five mortalities in India. Secondary-level neonatal intensive care units (NICUs) currently provide care to majority of sick newborns in India. Only few clinical studies have described the management outcome of newborns admitted into these secondary-level NICUs in India. Methods: The current study was conducted in Koraput District Headquarter Hospital and associated Medical College Hospital located in tribal regions of Odisha catering to 13.8 lakhs population of predominantly lower socioeconomic status. The study included in-depth retrospective case record analysis of all the NICU admissions in 3 months between April and June 2018, after a broad overview of all admissions in 3 years between July 2015 and June 2018. Predesigned pro forma was used to document clinical profile, indication for admission, microbiological characteristics of neonatal sepsis, and outcome in terms of discharge, death, referral, or left against medical advice. Results: Of 4127 total NICU admissions between July 2015 and January 2018, 3159 (76%) newborns were discharged. The most common indications for admissions in inborn babies were prematurity and related complications (23%), birth asphyxia (19%), and neonatal hyperbilirubinemia (18%). For outborn newborns, along with these causes, neonatal sepsis (20%) was another important cause of NICU admission. Escherichia coli and Klebsiella species were predominant microorganisms to be isolated in blood culture. About 11% of newborns received kangaroo mother care, with median duration of 6 days. Predominant causes of death among newborn babies were prematurity-related complications (51%) and neonatal sepsis (37%). Conclusion: Prematurity-related complications, birth asphyxia, neonatal hyperbilirubinemia, and sepsis are the predominant indications for admission to a secondary-level NICU in India. About three-fourth of neonates can be treated successfully within the existing infrastructure.
Effects of Health Belief Model-Based Education on Health Beliefs and Breast Self-Examination in Nursing Students

Objective: This study was carried out to investigate the effect of an education program based on the health belief model (HBM) on nursing students' health beliefs and on their practices of breast self-examination (BSE). Methods: This research was a semi-experimental intervention study with a single group, pretest and posttest design. The sample of the research consisted of 48 students in the 3rd year of study. Data were collected before the education program and 6 months and 1 year after the training. A sociodemographic information form, the breast cancer knowledge form, the HBM scale, and the BSE proficiency rating instrument were used. Descriptive statistics and repeated measures ANOVA were used to examine the relationships among the variables. Results: Implementing the educational program was found to be statistically insignificant for the HBM. Knowledge about breast cancer and BSE skills increased after the training. The percentage of students practicing regular BSE was determined as 14.6% before training, 45.8% after 6 months, and 28.1% after 1 year. Conclusions: The education provided to the students increased their HBM scores, knowledge about breast cancer, and BSE skills. However, the frequency of regular BSE was still quite low after training.
Results of a Preventive Rebleeding Protocol in Patients with Ruptured Cerebral Aneurysm: A Retrospective Cohort Study

Objective: In 2015, a protocol to prevent rebleeding was implemented to improve the outcome of patients with ruptured intracranial aneurysm. We performed a single-center retrospective analysis to compare the outcomes of pre/post using protocol. Methodology: Over a 3-year period, 208 patients with ruptured cerebral aneurysm were treated at our institution. The protocol for preventing rebleeding was initiated in 2015. We compared the two cohorts between the group of patients before initiating the protocol (n = 104) and after initiating the protocol (n = 104). We analyzed the protocol for preventing rebleeding which consisted of absolute bed rest, adequate pain control, avoiding stimuli (R), keeping euvolemia (E), preoperative systolic blood pressure <160 mmHg and within 140–180 mmHg after definite treatment (S), a short course (<72 h) of intravenous transaminic acid, and aneurysm treatment as early as possible (T). Outcomes are presented as in-hospital rebleeding, delayed cerebral ischemia (DCI), and proportion of unfavorable outcomes (score of 4–6 on a modified Rankin scale at 6 and 12 months). Results: Postprotocol, there was a reduction in the incidence of in-hospital rebleeding from 6.7% to 2.8% (P = 0.20, odds ratio [OR] = 0.4, 95% confidence interval [CI] = 0.10–1.63) and in the proportion of patients who presented with good WFNS grades (1–3) with unfavorable clinical outcomes at 12 months from 27.0% to 12.8% (P = 0.03, OR = 0.40, 95% CI = 0.17–0.95). The DCI experienced a significant reduction from 44.2% to 7.7% (P < 0.001, OR = 0.10, 95% CI = 0.04–0.23), and their 180-day mortality rate in good WFNS grades patients decreased from 16.3% to 8.8% (hazard ratio 0.80, 95% CI = 0.28–2.28). Conclusion: Ruptured cerebral aneurysm patients benefit from this protocol due to its ability to reduce the incidence of DCI and reduce unfavorable outcome on good WFNS grade patients.
Comparison of 0.125% levobupivacaine with dexmedetomidine and 0.25% levobupivacaine in ultrasonography-guided pediatric caudal block: A prospective, randomized, double-blinded study

Background: Caudal anesthesia is a safe and reliable technique for infraumbilical surgeries in pediatric patients. Addition of dexmedetomidine to local anesthetic (LA) in caudal block prolongs the duration of block, but the effect on reducing the concentration of LA drug has not been extensively evaluated. This study was, therefore, designed to evaluate the efficacy of addition of dexmedetomidine to lower concentration of levobupivacaine required for ultrasonography (USG)-guided caudal block. Methods: A total number of 60 children with American Society of Anesthesiologists Grade I and II, aged 2–8 years from both sexes, and undergoing infraumbilical surgeries were recruited in a prospective, double-blinded, randomized controlled study over a duration of 1 year. The study children were allocated into groups A and B (n = 30 each) via computer-generated randomization. Group A children received caudal 0.25% levobupivacaine 0.75 ml/kg with 1 ml of normal saline and Group B children received 0.125% levobupivacaine 0.75 ml/kg with 1 μg/kg dexmedetomidine in 1 ml of normal saline after induction and the insertion of I-gel. Heart rates, blood pressure, and SpO2were monitored perioperatively. Postoperative hemodynamic monitoring; face, legs, activity, cry, and consolability (FLACC) pain score up to 24 h; time to first rescue analgesia; and emergence delirium using Watcha scale and Ramsay sedation score were recorded. Rescue analgesia was administered when FLACC pain score was >4. Any adverse events were noted and documented. Results: The study groups were comparable in terms of demographic characteristics and nature/duration of surgery. The mean FLACC pain scale in Group B was significantly lower compared to Group A. The mean duration of analgesia was statistically prolonged in Group B (P < 0.05) as compared to Group A (1299 ± 145 min in Group B vs. 348 ± 36 min in Group A). Emergence delirium as measured by Watcha scale was significantly lower in Group B (P < 0.05). Perioperative hemodynamic parameters were stable in the two groups, and no clinically significant adverse effects were noted. Conclusion: Addition of 1 μg/kg of dexmedetomidine decreases the effective concentration of levobupivacaine required for USG-guided caudal block, extends the duration of analgesia, and lowers the incidence of emergence delirium among pediatric patients undergoing infraumbilical surgery.
