Public health leadership competency level among health professionals in a South Eastern European country

Aim: The aim of this study was to describe the current and the required leadershipcompetency level of health professionals in Albania, employing a recently establishedinternational instrument. Methods: A nationwide cross-sectional study was conducted in Albania in July-December 2014 including a representative sample of 267 health professionals (162 men and 105 women; mean age: 44.7±10.3 years; overall response rate: 89%). A structured questionnaire was administered to all health professionals aiming at self-assessing the current level of leadership competencies and the required (desirable) level of leadership competencies for their current job position. The questionnaire included 52 items grouped into eight subscales/domains. Answers for each item of the tool ranged from 1 (“minimal competency level”) to 5 (“maximal competency level”). An overall summary score (range: 52-260) and a subscale summary score for each domain were calculated for both the current and the required leadership competency levels. Wilcoxon signed ranks test was employed to comparethe overall scores and the subscale scores of the current and the required level of leadership competencies among health professionals. Results: Mean value of the overall summary score for the 52 items of the instrument was significantly lower for the current leadership competency level compared with the required leadership competency level (138.4±11.2 vs. 159.7±25.3, respectively; P<0.001). Most of the subscales’ scores were significantly higher for the required than for the current leadership competency level. Conclusion: Our study provides useful evidence about the current and the required level of leadership competencies among health professionals in transitional Albania. Findings of this study may help policymakers in Albania to identify the gap between the required and the current level of leadership competencies among health professionals. Furthermore, findings of this study should be expanded in the neighbouring countries of the South Eastern European region and beyond.
A first-time investigation of psychosocial inclusivity in design; inclusive supermarket design for older individuals

As a first-time investigation of 'psychosocial inclusivity' in design, this paper introduces and establishes the concept of psychosocially inclusive design, and explores it within the context of supermarket shopping for older individuals, as one instrumental activity of daily living. Inclusive design theory and practice have been predominantly concerned with issues of physical access, limiting its scope and relevance to the wider more complex psychosocial issues. Employing research triangulation and rigorous empirical investigations, this paper advances the fundamental understanding, extends the general research agenda, and pushes the current boundaries of inclusive design towards non-physical inclusion by identifying any possible psychosocial constructs. Four constructs including 'cognitive', 'emotional', 'social', and 'value' were identified in the context of supermarket shopping through ethnographic interviews; creative workshop; and observations conducted with a total of 58 older individuals. The results may play a crucial role in establishing the theoretical foundations to the concept of psychosocial inclusivity in design.
Timber-Framing Construction in Herculaneum Archaeological Site: Characterisation and Main Reasons for its Diffusion

ABSTRACT Timber-framing is the most common mixed construction technique utilised by Romans and many other builders throughout history. However, archaeological evidence is scarce due to the overlapping urban land use and the perishability of the wooden skeleton. This paper focuses on timber frame wall — opus craticium — from Herculaneum, examined through a literature review and on-site analysis. The aim of this research is shedding light on the reasons for the diffusion of opus craticium through a critical analysis of Vesuvian archaeological evidence, among which the best-known is Casa a Graticcio (Insula III, 13–15, Herculaneum). The dichotomy between the written transmission of this technique and the construction practice in the Augustan epoch is also discussed. It is shown how the pervasiveness of this technique in Herculaneum arises from multiple reasons: firstly, the strong demand of new constructions and the need of heavy repairs during the Augustan Principate. Additionally, the anaerobic conditions resulting from the specific on-site burial in 79 AD allowed the conservation of the timber-framing.
Mammogrphic Screening Provided by the National Health Insurance Corporation: A 1 year Audit in a Secondary Medical Institution1

Purpose: We performed a medical audit of the mammograms performed as part of the existing public cancer screening program to propose a plan for improving the program. Materials and Methods: We analyzed the results of 3,317 mammograms performed between March 2006 and February 2007. The American College of Radiology Breast Imaging Reporting and Data System (ACRBI_RADS) guidelines were used for follow-up and outcome monitoring. Cases in categories 0, 4, and 5 were followed up by a review of the patient's medical records and a phone call survey to determine the reasons for not continuing with follow-up examinations. Results: The mean age of the women enrolled in this study was 51 years. The rate of recall was approximately 6.4% and the cancer detection rate was 2.1 out of every 1000 women examined. Positive predictive values (PPV) of 1, 2 and 3 were observed in 3.3%, 33.3% and 70.0%, respectively. The sensitivity and specificity were 100% and 93.8%, respectively. As a result of the phone-call survey to determine the reasons for not following up with additional examinations, 53.8% of cases were 'belittled since there was no subjective symptom,' and 16.3%, 'didn't check the cancer examination notice thoroughly or did not fully understand it'. Conclusion: The result of medical audit indicates that reading and follow-up examinations were conducted in a relatively proper manner. Taking into consideration the characteristics of the objects for public examination, it is thought that active follow-up management as well as a written notice of the results, is necessary for patients who were found to be abnormal.
Impact of Time Zero Variability and BTI Reliability on SiNW FET-Based Circuits

In this work, negative bias temperature instability/positive bias temperature instability (NBTI/PBTI) reliability model for p/n-silicon nanowire (SiNW) MOSFETs is obtained from experimental SiNW FETs using a range of stress voltage, time, and temperature. We have incorporated the NBTI/PBTI $\text{V}_{\mathrm{ T}}$ model in a physics-based SiNW FET Verilog-A compact model for circuit analysis. For the first time, using integrated model, we report time zero variability and BTI reliability of the core logic gates (INVERTER, NAND, and NOR) and read/write stability of 6T SRAM cell. We demonstrate that the delay degradation is circuit topology dependent in which series-connected transistors are more prone to degradation due to PBTI (NBTI) in NAND (NOR) gates. The benchmarking of BTI in SiNW FET with FinFET and planar devices show SiNW have higher degradation, however it can be minimized by using optimized SiNW FET configuration. Further, we show that the SRAM cell design margins are configuration dependent in which impact of BTI degrades the read noise margin (RNM) by 15–30%, and write noise margin (WNM) improves by 5–8% for 10-Year lifetime. We find that the combined impact of time zero variability and BTI reliability degrades the mean value of circuit delay and SRAM RNM stability, however, the degradation is found to be comparable to the reported planar and FinFET data. It is also seen that different configuration increases BTI variability (~5-25% increase) which can be minimized. Using the results, we propose a method to minimize degradation under the influence of variability and reliability by selecting appropriate SiNW FET design configuration. The comprehensive predictive model framework presented here is a valuable tool for variability and reliability-aware SiNW CMOS circuit design and analysis.
Engaging parents with sex and relationship education: A UK primary school case study

Objective: To assess an intervention to familiarise parents with children’s books for use in primary (5–11 years) sex and relationship education (SRE) classes. Method: Case study of a 7-week programme in one London primary school, using ethnographic observation, semi-structured interviews and focus groups with parents (n = 7) and key stakeholders (n = 4), and pre- and post-programme self-completion questionnaires (n = 9). Results: Parents reported increased understanding of the SRE curriculum and awareness of relevant children’s books, enhanced interactions with their children on SRE topics and some positive effects on partners and attitudes towards the school. There was increased confidence in addressing issues in the SRE curriculum for parents of 8- to 10-year-olds, although reduced confidence for one mother. Conclusions: Familiarising parents with materials has the potential to enhance SRE, by improving coherence between educators’ and parents’ messages to children about sex and relationships, increased discussion of SRE topics in parent–child conversations and reduced parental anxiety about topics such as sexual orientation. Future challenges of involving fathers, scalability and sustainability highlight the dilemma of how best to enable parental choice or make equalities interventions.
Triacetin Production From Glycerol Using Heterogeneous Catalysts Prepared From Peat Clay

Glycerol, an abundant by-product of biodiesel production, is urgently considered to increase its usage. Triacetin produced from glycerol is an important material, used in polyester, cryogenics, cosmetics and as a biodiesel additive. Using homogeneous catalysts in triacetin production involves high product separation costs. The purpose of this study is to synthesize heterogeneous catalysts based on alumina and silica from peat clay for use in the production of triacetin from glycerol. The conversion of glycerol for triacetin production using such alumina and silica catalysts yielded levels of 82.7% and 87.4%, respectively. These values were greater than the conversion value of 71.2% using a sulfuric acid homogeneous catalyst. An optimum conversion of 91% was obtained at the mole ratio of glycerol to acetic acid of 8.9. The potential heterogeneous catalysts were confirmed by the results of SEM, XRD and BET characterization. Therefore, the production of triacetin using heterogeneous silica catalyst could be an alternative approach in commercial processes which currently using homogeneous catalysts.
Enhanced Power Capability of Generator Units for Increased Operational Security Using NMPC

The ever-increasing penetration of intermittent energy sources introduces new demanding operating regimes for the bulk power generation in the power grid. During a worst-case power system disturbance scenario, the generator needs to operate beyond its limits to maintain stable operation. Therefore, a new online low-order thermal model of a hydrogenerator has been recently proposed, where the periodic extension of the long-forgotten capability diagram of the machine was in-depth investigated. An increased performance can be obtained if the total thermal capacity of the generator is exploited by applying optimal control theory in the Automatic Voltage Regulator (AVR). This paper proposes a Non-linear Model Predictive Controller (NMPC) combined with an Unscented Kalman Filter (UKF) with a modeling framework geared for use in a supervisory control structure for the conventional control system. The method provides maximum utilization of the machine's thermal capacity by providing the controller with an Enhanced Capability Diagram (ECD). Case studies on a single-machine system and a 16-bus multi-machine system were investigated. The results show that a satisfying controller action during different long-term voltage instability scenarios is realized.
Assessment of the Nutritional Status of first year primary school children in El Horga village, Gezira state

Objective: To assess the nutritional status of first year primary school children in El Horga village as a basis for further intervention. Methods: A cross-sectional study was conducted in all first year primary school children, aged 6-7 years, in El Horga village, in the Gezira State, central Sudan, 53 males and 62 females. The study was designed to assess the nutritional status using clinical signs, standard anthropometric measurements and biochemical investigations. Results: Mean anthropometric measurements were 19.1± 2.6 kg for weight, and 112.5±5.1 cm for height. Compared to National Center for Health Statistics (NCHS) reference parameters, 63.5% of children were stunted (height for age, H/A <-2 Z score), 18.3% were wasted (weight for height, W/H <-2 Z score) and 57.5% underweight (weight for age, W/A< -2 Z score). Mean for mid upper circumference (MUAC) was 16.7± 0.2 cm, and 8.4± 0.19 mm for triceps skin fold (TSF). According to MAUC, 45.2% of children suffered malnutrition, 28.7% were moderately undernourished and 16.5% were severely undernourished. Significantly low adipose tissue stores were found in 41.8%. Biochemical results were as follows: mean haemoglobin (Hb) concentration of all children was 11.4±1.2 g/dl, PCV 34.1±2.2%, MCHC 32.8±2.4g/dl. total serum protein 6.8±0.9 g/dl, serum albumin 4.0±0.8 g/dl, serum iron 50.2±21.2µg/dl, TIBC 266.6±51. 6µg/dl, and 21.2±8.6% transferrin saturation. 56.5% of the study group were anaemic (Hb<11g/dl) and 30.4% suffered from iron deficiency anaemia with transferrin saturation <15%. Conclusion: The children under study were shorter and lighter as compared to reference standards. A considerable number were anaemic. Consequently, the nutritional status of children should be further investigated and improved through nutritional programmes and food fortification. Key words: nutritional status, primary school children, Sudan.
Effects of Different Tire Operating Conditions on Transient Lateral Tire Response

The concept of the relaxation length is often used to describe a tire's transient response. This paper investigates how the transient response changes under different operating conditions. Through the measurement of tire forces and tire deformations during transient maneuvers performed on an indoor flat-belt tire test machine, experimental data were used to calculate various tire stiffnesses and the associated relaxation lengths using a novel method via optimization. With this methodology, the effects of tire load, inflation pressure, speed, and temperature on these stiffnesses and the relaxation length have been identified. The mechanisms behind these effects are discussed with a particular focus on the influence of temperature.
Improving Accuracy and Reliability of Bluetooth Low-Energy-Based Localization Systems Using Proximity Sensors

One of the functionalities which are desired in Ambient and Assisted Living systems is accurate user localization at their living place. One of the best-suited solutions for this purpose from the cost and energy efficiency points of view are Bluetooth Low Energy (BLE)-based localization systems. Unfortunately, their localization accuracy is typically around several meters and might not be sufficient for detection of abnormal situations in elderly persons behavior. In this paper, a concept of a hybrid positioning system combining typical BLE-based infrastructure and proximity sensors is presented. The proximity sensors act a supporting role by additionally covering vital places, where higher localization accuracy is needed. The results from both parts are fused using two types of hybrid algorithms. The paper contains results of simulation and experimental studies. During the experiment, an exemplary proximity sensor VL53L1X has been tested and its basic properties modeled for use in the proposed algorithms. The results of the study have shown that employing proximity sensors can significantly improve localization accuracy in places of interest.
Recovery of Incapacitated Commercial Delivery Drones Using LPWAN Technology

This paper proposes for the first time the use of an Internet of Things solution for the accurate recovery of incapacitated commercial and retail delivery drones. Since the use of drones will increase in popularity for a variety of uses, the problem of locating and recovering delivery drones is necessary. Using the emerging LoRaWAN and Sigfox networks (as examples of Low Power Wide Area Network (LPWAN) technology), we investigate the opportunity to locate and recover delivery drones that have crashed either due to technical issues or outside malign intervention. Location and recovery of a test drone using LoRa technology was trialed over three distinct terrains (urban, suburban, and rural) at five different sites in each terrain. These 15 trials evaluate ease of recovery on arrival at the crash site, accuracy of location coordinates given, and a subsequent analysis of the channel statistics for the LoRa network. The experiment was repeated using the Sigfox network as a comparison. The drone was able to be recovered at 14 of the 15 tests sites for both LoRa and Sigfox; in every case the drone's location was successfully transmitted to the secure server via the LPWAN networks. The paper investigates the reported location accuracy from the drone and also uses RMSE as an accuracy metric. The paper furthermore divulges lessons learned and presents a drone recovery algorithm.
Application of Alvarado Scoring System in Diagnosis of Acute Appendicitis

From the Department of Surgery, Government Medical College, Jammu. Correspondence to : Dr. Kailash Singh, Flat No. 13, Old Block 7, Police Housing Complex, Gandhi Nagar, Jammu. Introduction Acute Appendicitis is the most common abdominal emergency in both developed and developing countries(1,2). Approximately 6% of the population will suffer from acute appendicitis during their life time (3, 4). Diagnosis of acute appendicitis is difficult & its complications more in young children & the elderly(5). Acute appendicitis is a clinical diagnosis and no laboratory or radiological tests are 100% accurate(6). Delay in diagnosis and management may increase the morbidity & costs.Lots of efforts have been directed toward early diagnosis and treatment of acute appendicitis. A number of scoring systems have been used for aiding in early diagnosis of acute appendicitis and its prompt management. Scoring systems are valuable and valid instruments for discrimating between acute appendicitis and non specific abdominal pain (7). One of the scoring systems is the Alvarado Scoring System which is purely based on history, clinical examination and few laboratory tests and is very easy to apply (8). This study was conducted to evaluate the usefulness of this scoring system. Material & Methods This prospective study was conducted on 100 consecutive patients admitted in one surgical unit of Govt. Medical College, Jammu with the clinical diagnosis of acute appendicitis between Dec. 2006 to June 2007. Patients of any age group and both sexes presenting to emergency department with symptoms of acute appendicitis were included in the study. Patients presenting with urological, gynecological or other surgical problems including patients with mass in right iliac fossa were excluded from this study.All the patients were admitted. Baseline investigations, Hb, TLC, DLC, RFT, Urine Examination, X-ray Chest, X-ray KUB and ECG were done.A Proforma containing general information about the patient plus eight variables based on the Alvarado scoring system (Table-1) was filled.

A Nanomechanical Genosensor Using Functionalized Cantilevers to Detect the Cancer Biomarkers miRNA-203 and miRNA-205

We report a nanomechanical genosensor based on an atomic force microscope (AFM) cantilever functionalized with complementary strands of miRNA-203 and miRNA-205, which are potential biomarkers of metastasis in head and neck squamous cell carcinomas (HNSCC), especially in cervical lymph nodes. Hybridization with the corresponding complementary strand led to cantilever deflections that increased almost linearly with the concentration of either miRNA-203 or miRNA-205 in the fluid cell where AFM experiments were made. The detection limit was ca. 95 nM and 97 nM for miRNA-203 or miRNA-205, respectively, with higher deflections observed for miRNA-205 due to the larger number of interaction groups during hybridization. Selectivity was proven by measuring negligible cantilever deflections for non-specific miRNA sequences. The cantilever functionalization process during genosensor design was confirmed by fluorescence microscopy and AFM imaging. The use of a single genosensor platform for detecting different miRNA molecules is advantageous for diagnosis and prognosis of cases where multiple biomarkers may be relevant, as in the case of HNSCC metastasis.
Methanol Marker for the Detection of Insulating Paper Degradation in Transformer Insulating Oil

This manuscript presents a comprehensive literature review with the aim to provide readers a reference document with up-to-date information on the field of methanol use as a chemical marker. It has been a little more than a decade since methanol was first introduced as a marker for assessing solid insulation condition in power transformers. It all started when methanol was identified in the laboratory during thermal ageing tests carried out with oil-immersed insulating papers and was subsequently also identified in transformer field samples. The first publication on the subject was released in 2007 by our research group. This review covers the methanol fundamentals such as the analytical methods for its determination in transformer oil, which is generally performed by headspace gas chromatography with mass spectrometry or flame ionization as a detector. Current standardization efforts for its determination include ASTM working group 30948 and IEC TC10. Kinetic studies have confirmed the relationship between methanol generation, the number of broken 1,4-β-glycosidic bonds of cellulose and changes in mechanical properties. Laboratory tests have confirmed its stability at different accelerated ageing temperatures. Several utilities have identified methanol during field measurements, case studies on power and some distribution transformers are presented, as well as transformer postmortem investigations. These field-testing results demonstrate its utility in monitoring cellulosic insulation degradation. Recently, a model of methanol interpretation has become available that allows for evaluation of the average degree of polymerization of core type transformer cellulose winding. Methanol has a role as an indicator of cellulosic solid insulation ageing in transformer mineral oil, and it is expected that in the future it will be in routine use by utilities.
