High adhesion tin monoselenide SnSe layers with a thickness of up to 200 ± 10 nm have been prepared by hydrochemical deposition from a trilonate reaction mixture. It was revealed by the X-ray diffraction method that the synthesized films crystallize in the orthorhombic system (S. G. Pnma). The presence of a significant amount of oxygen in the surface layers of the films is explained by partial oxidation of the samples with the formation of the SnO2 phase. The results of ion etching to a depth of 18 nm showed a sharp decrease in the oxygen content with depth and actual correspondence of the elemental composition to SnSe. According to the results of optical studies, the band gap was found to be 1.69 eV for direct type of transitions, respectively. The synthesized SnSe layers have a hole-type conductivity typical of this material.

One can reasonably expect that the properties of metallic glasses should be related with the properties of the maternal crystals used for their preparation. This issue, however, is not raised in the literature, with a few exceptions. The paper briefly summarizes the results of a comparison of the changes of the shear modulus, density and kinetics of the thermal effects in metallic glasses occurring during structural relaxation, in the supercooled liquid state and upon crystallization. It has been demonstrated that the magnitudes of the thermal effects as well as density variations can be predicted considering the changes of the shear modulus of the glass with respect to the shear modulus of the maternal crystal, which indicates a genetic relationship between the properties of the glass and those of the maternal crystal. In this case, in an energetical sense, the maternal crystal can be interpreted as a ground state of the glass, the excess internal energy of which is determined by the elastic energy of the system of interstitial-type “defects” occurring upon melting and subsequent melt quenching.

The electronic structure and optical properties of the binary intermetallic compound FeSb2 have been studied. The band structure was calculated in the local density approximation, which showed the existence of a narrow ~0.3 eV gap in the energy spectrum of this material. The spectral characteristics were studied by ellipsometric method in the wavelength range of 0.22-18 μm. It is shown that the experimental optical conductivity of the compound in the region of interband transitions is satisfactorily interpreted in the framework of the calculations of the density of electronic states. The work was performed as part of the state assignment of the Ministry of Education and Science of the Russian Federation (theme Electron, N AAAA-A18-118020190098-5) with partial support from the Russian Foundation for Basic Research (project N 17-52-45056).

AbstractWe present the data of studies on the structure, phase states, and magnetic properties of magnetic nanoparticles (MNPs) of magnesium ferrite spinel (MgFe_2O_4), synthesized by ultrasonic aerosols pyrolysis. Primary single-phase MNPs with an average size of 9.6, 11.5, and 14.0 nm, synthesized from precursors at concentrations of 0.06, 0.12, and 0.24 M, respectively, agglomerate into tightly aggregated spherical particles (secondary particles) with sizes of 206, 300, and 340 nm, respectively. Primary particles inside the spheres do not interact with each other and are in a superparamagnetic state. There is a layer on the surface of the particles, the magnetic structure of which differs from the structure of the inner part of the MNP; this is explained by the formation of a canted spin structure or a spin glass state in the surface layer of the MNPs. MgFe_2O_4 nanospheres obtained from a precursor at a concentration of 0.06 M are most promising as valid sources of heat in magnetic hyperthermia therapy.

AbstractThe parameters of atomic interaction pair potential for ^13C diamond have been determined from experimental data on the ratio of Raman frequencies for isotopically different diamonds. Based on these parameters, an equation of state and baric dependences of ^13C diamond lattice properties at 300 K have been calculated. Specifically, the Debye temperature; the first, second, and third Grüneisen parameters; elastic modulus; thermal expansion coefficient; heat capacity; surface energy; and pressure derivatives of these parameters along a 300 K isotherm have been determined. The results have been compared with available data for diamond having a natural isotopic composition, i.e., for ^12.01C.

AbstractThe composition and parameters of energy bands in thin SiO_2 films grown on the surface of a free Si/Cu film system have been studied. It has been shown that unlike SiO_2 films grown on thick films, the value of E _ g for thin SiO_2 films is no higher than ~4.1 eV. This is explained by the presence of Si impurity atoms and nonstoichiometric oxides in the SiO_2 film, which arise because of the impossibility of heating the system above 700 K.

AbstractIt was shown that the interaction of silver cations in alkaline aqueous solutions with various kinds of silicates, regardless of their chemical and aggregation state, leads to the formation of an exclusively disilicate form of silver salt. We develop procedures for synthesis of nanostructured weakly ordered nonstoichiometric silver disilicate Ag_6 –_ x H_ x Si_2O_7 capable of forming aqueous colloids. We study the micellular structure of colloidal particles in these solutions and demonstrate that permeability of silicic acid layers enveloping nanosized salt cores of these micelles depends on pH. Colloidal silver disilicate is found to exhibit a high catalytic activity in photoinduced oxidation of a broad spectrum of different compounds, which is demonstrated for compounds stable in aqueous solutions such as some organic dies and ferrocyanide complex ([Fe(CN $$)_{6}^{{ - 4}}$$ ).

Published: May 2019

In the Rayleigh–Gans–Debye approximation an analytical solution is obtained for the problem of second harmonic generation by a plane electromagnetic wave with elliptical polarization from a thin optically nonlinear layer on the surface of a cylindrical dielectric particle of finite size placed in a dielectric. The result is presented in tensor and vector forms in general case, in which the nonlinear dielectric susceptibility tensor has four independent components (one chiral and three non-chiral). For the first time it is shown that at generation from the end plane surfaces of a cylindrical particle the contribution of chiral components differs in phase from that of non-chiral components. It is also found that for small linear dimensions of the cylindrical particle (height and radius of the base), the radiation due to the chiral component of the second-order nonlinear dielectric susceptibility tensor makes a dominant contribution to the second harmonic generation from a non-linear cylindrical layer (end and side surfaces).

More than 50 different combinations are given for parameters of the problem of second harmonic generation by a plane electromagnetic elliptically polarized wave from a thin optical layer on the surface of cylindrical particle, in which the generation from the lateral surface cannot be observed. Also, 18 combinations of parameters are found, in which generation from the end surfaces of the cylindrical particle is not observed. More than 30 problem parameter combinations are given, in which linearly polarized second harmonic radiation is generated from the side surface (or from the end surfaces). The combinations of problem parameters are indicated, at which generation from the entire surface of the cylindrical particle cannot be observed, and also parameter combinations at which the generation has linear polarization. A method is proposed for determining the anisotropy coefficients on the base of the properties above.

Using X-ray phase analysis, scanning electron microscopy atomic force and magnetic force microscopy, and IR spectroscopy the properties of polycrystalline TiO2 films modified by cobalt during magnetron sputtering and subsequent pulsed photon processing in air have been investigated. It has been found that in the course of the modification, a nanocrystalline (with a grain size of ~ 50 nm) film consisting of cobalt and titanium oxides is formed. Their surface exhibits magnetic properties. In the IR reflection spectra obtained at different incident angle of beam, two of the transverse optical (TO) phonons and their corresponding longitudinal (LO) phonons above 500–600 cm–1 were observed, which identify the formation of Co3O4 in the spinel structure. The study of optical absorption indicates the predominant existence in the films of phases with direct optical transitions. The optical band gap value was 1.43 and 1. 83 eV for Co3O4 and 2.65 eV for the cubic phase of CoO.

Methods of multicomponent spectral analysis of exhaled air based on application of tunable diode lases were proposed for biomedical diagnostics. Simmultaneous laser based spectral analysis of the gas pairs like CO and CO2, and CO and N2O in the 4.7 micron spectral region could be used for investigation of gas exchange in studies on breathing phisiology and cardiovascular diagnostics conducted with application of different loading tests, as well as for studies in anesteziology and for on-line monitoring of ventilation-perfusion ratio. Simmultaneous analysis of NO and CO2 in 5.4 micron region could be useful fot the control of breating maneuver in studies of inflammation processes in the distal part of the lungs. Simmultaneous detection of NH3, СO2 and C2H4 near 10.5 m could be promising in studies of basal metabolizm and metabolis cycles. Simmultaneous analisis of 13СO2 and 12С O2 near 2.05 m could be used for the detection of 13СO2/12СO2 izotope ratio for izotope breath tests. The results of promising spectral region analysis and of mutual location of absorption analytical lines in these regions are presented. A possibility of simmultaneous detection of several studied molecules in the provided spectral regions was experimetally demonstrated as well as experimental laser spectra of molecular absorption were obtained.

The paper presents the results of the study of charge carrier transport and deep level recharging in semiconductor structures for ionizing radiation detectors. The resistive gallium arsenide structures with Schottky barriers and a uniform distribution of the deep chromium acceptor and the deep EL2 donor centers were studied. The effect of depletion of the volume of detector structures with electrons has been found by solving the continuity and Poisson equations with the use of a commercial software. It is found that the nonlinearity of the current-voltage characteristics of the structures is associated with change in the conductivity type under transition from an equilibrium to a nonequilibrium state. In this case, the structures with the initial equilibrium p-type conductivity have current-voltage characteristics close to linear.

AbstractWe have experimentally studied the influence of solid impurity particles present in aqueous aerosol droplets on their interference patterns. The interference patterns were studied with the aid of a Nd:YAG laser and CCD video camera. The radii of droplets in the aqueous aerosol ranged within 10–140 μm. Solid particles of four materials were introduced in the aerosol to a mass concentration of 0.003–1 g/L. Specific types of interference patterns determined by the presence of solid impurities in droplets are described, and the influence of impurity type and concentration on the integral characteristics of these patterns (number and type of images) is established. A new approach to determining the impurity concentration and particle dimensions in aerosols is proposed based on the analysis of their interference patterns.

Mental Health Promotion Among University Students Using Text Messaging: Protocol for a Randomized Controlled Trial of a Mobile Phone–Based Intervention
Authors: Thomas Kristin , Bendtsen Marcus
Published: May 2019

Background

There is a growing understanding that well-being and mental illness are 2 separate dimensions of mental health. High well-being is associated with decreased risk of disease and mental illness and increased longevity.

Objective

This study aims to test the efficacy of a mobile phone–based intervention on positive mental health.

Methods

We are conducting a 2-armed randomized controlled trial of university students in Sweden. Recruitment will last for 6 months by digital advertising (eg, university websites). Participants will be randomly allocated to either an intervention (fully automated mobile phone–based mental health intervention) or control group (treatment as usual). The primary outcome will be self-assessed positive mental health (Mental Health Continuum Short Form). Secondary outcomes will be self-assessed depression anxiety symptomatology (Hospital Anxiety Depression Scale). Outcomes will be investigated at baseline, at 3, 6, and 12 months after randomization. Mediators (positive emotions and thoughts) will be investigated at baseline, midintervention, and at follow-ups using 2 single face-valid items.

Results

Data will be collected between autumn 2018 and spring 2019. Results are expected to be published in 2020.

Conclusions

Strengths of the study include the use of a validated comprehensive instrument to measure positive mental health. Mechanisms of change are also investigated. A potential challenge could be recruitment; however, by setting a prolonged recruitment period, we believe that the study will recruit a sufficient sample.

Negative Refractive Index in Nanoparticles Layer at the Visible
Authors: Ali Hanan , Zhang Guoping
Published: May 2019

Metamaterial structure based on epoxy resin nanoparticles positioned on mica glass substrate is proposed in order to produce negative refractive index. Complex reflection and transmission coefficients (S-parameters) are computed using CST MWS, based on finite integration technique (FIT) which is equivalent to FDTD when applied to Cartesian grids in the time domain. Effective refractive index, effective permittivity and effective permeability were extracted from the simulated S-parameters by using CST MWS extraction method which is done by using template pots-processing features. The real part of the refractive index is found to be negative at wavelengths where both real parts of the permittivity and permeability are negatives without using split ring resonators and thin wires.
Assessing the Impacts of Urban Sprawl on Suburban Villages in the Bamenda Metropolitan Periphery, North West Cameroon
Authors: FUBE Eleno Manka’a
Published: May 2019

Man has been and remains mobile, conquering and impacting every space he occupies. Man’s impact on space has been more accentuated since the 20th century than erstwhile in history, owing to demographic explosion and more advanced technological innovations. Urban space and adjoining lands are impacted most compared to the rural milieu. This study examines the ramifications of rapid and disordered urbanisation on peripheral villages to the city of Bamenda. This is crucial in understanding the threats and consequences of the phenomenon of unending urbanisation on contiguous agricultural land. The trend of urbanisation and resultant impacts were ascertained by analysing data drawn from national census figures, LANDSAT satellite images and suitable field surveys. Analyses revealed that a growth of 14.6% of the population between 1973 and 2018 produced a corresponding sprawl of 97.54% of the spatial extent of Bamenda metropolis, which presently covers 40.96 times the spatial area it occupied in 1973. This has grave repercussions for contiguous agricultural land and urban food security. The paper posits that a scrupulous compliance with existing urban master plans and implementation of carefully designed policies to protect agricultural land are inevitable in checking urban growth and its induced effects; and guaranteeing urban food security.

High plasma lipids interact with free radicals in human body leading to develop coronary artery disease.  We in this study have compared hypolipidemic effects of Fenugreek, Curcuma Longa, and lemon. Study was conducted at Jinnah Hospital Lahore-Pakistan from January 2018 to May 2018. Ninety hyperlipidemic patients of age group 19 to 70 were included in the study. Exclusion criteria were diabetic, alcoholic additives, hypertensive patients and those whose kidney or liver functions were impaired. Consent was taken from all participants. Their base line lipid profile was taken in biochemistry laboratory of the hospital. They were divided in three groups i.e. 30 patients in each group. Group-I was advised to take 500 mg of Curcuma Longa (haldi) mixed in fresh milk without cream, thrice daily for two months. Group-II patients were advised to take 100 grams of Fenugreek leaves mixed with salad in each meal (thrice daily) for the period of two months. Group-III patients were advised to take 40 ml of fresh lemon juice mixed with 40 ml mineral water thrice daily for two months. They all were advised not to take heavy meal rich with any type of fat like junk food etc. One hour daily brisk walk was advised to all participants. 15 days follow up visit was scheduled for them. After two months their lipid profile was re-determined. When results were compiled and statistically analyzed by applying paired ‘t’ test, it revealed that Curcuma Longa decreased total cholesterol, TG, LDL cholesterol 16.10, 20.01, and 17.59 mg/dl respectively. Fenugreek decreased total cholesterol, TGs, and LDL cholesterol 14.70, 17.33, and 17.06 mg/dl respectively. Lemon in two months therapy decreased total cholesterol, TGs, and LDL cholesterol 15.45, 10.13, and 11.97 mg/dl respectively. None of the above mentioned herbs raised HDL cholesterol significantly. It was concluded from this research work that Curcuma Longa, Fenugreek leaves and Lemon are mild to moderately effective hypolipidemic herbs to lower total plasma cholesterol, triglycerides, and LDL cholesterol but have no potential to raise HDL cholesterol when analyzed biostatistically.
Subsystem symmetries, quantum cellular automata, and computational phases of quantum matter
Authors: Stephen David T. , Nautrup Hendrik Poulsen , Bermejo-Vega Juani , Eisert Jens , Raussendorf Robert
Published: May 2019

Quantum phases of matter are resources for notions of quantum computation. In this work, we establish a new link between concepts of quantum information theory and condensed matter physics by presenting a unified understanding of symmetry-protected topological (SPT) order protected by subsystem symmetries and its relation to measurement-based quantum computation (MBQC). The key unifying ingredient is the concept of quantum cellular automata (QCA) which we use to define subsystem symmetries acting on rigid lower-dimensional lines or fractals on a 2D lattice. Notably, both types of symmetries are treated equivalently in our framework. We show that states within a non-trivial SPT phase protected by these symmetries are indicated by the presence of the same QCA in a tensor network representation of the state, thereby characterizing the structure of entanglement that is uniformly present throughout these phases. By also formulating schemes of MBQC based on these QCA, we are able to prove that most of the phases we construct are computationally universal phases of matter, in which every state is a resource for universal MBQC. Interestingly, our approach allows us to construct computational phases which have practical advantages over previous examples, including a computational speedup. The significance of the approach stems from constructing novel computationally universal phases of matter and showcasing the power of tensor networks and quantum information theory in classifying subsystem SPT order.

The study results showed health services access generally the community believes that there are still perceived defi ciencies. Especially on the aspect of physical access, due to poor facilities and infrastructure. In addition, social access was also considered inadequate, because there were still health workers who served with less friendly. This study concludes that people still feel access to physical and social aspects is still diffi cult. It should be recommended to the local government for eff orts to improve physical access, and the Health Offi ce to disseminate health information about the rights of patients to the community.

Abstrak

Akses pelayanan kesehatan seringkali dilihat hanya dari perspektif pemberi pelayanan saja, sementara akses dari sisi masyarakat sebagai pengguna kurang terperhatikan. Perbaikan kualitas pelayanan kesehatan dari sisi akses memerlukan perspektif yang lengkap dari dua sisi yang berbeda. Penelitian ini didesain secara deskriptif kualitatif. Data dikumpulkan dengan Focus Group Discussion (FGD), wawancara mendalam dan pengamatan. Penelitian dilakukan di Kabupaten Malang pada bulan Juni–Agustus 2018. Hasil penelitian menunjukkan aksesibilitas pelayanan kesehatan yang ada, secara umum masyarakat berpendapat bahwa masih ada kekurangan yang dirasakan. Terutama pada aspek akses secara fisik, dikarenakan sarana dan prasarana yang kurang baik. Selain itu akses secara sosial juga dirasa kurang, karena masih ada tenaga kesehatan yang melayani dengan kurang ramah. Penelitian ini menyimpulkan bahwa masyarakat masih merasa akses dari aspek fisik dan sosial masih sulit. Perlu direkomendasikan pada pemerintah daerah setempat untuk upayaperbaikan akses secara fi sik, dan Dinkes untuk mendiseminasikan informasi kesehatan mengenai hak pasien kepada masyarakat.

Various comments either support or rejection made by the hospital since the introduction of INA-CBGs tariff of the National Health Insurance (JKN) in January of 2014. Some hospitals complained about the unfairness of tariff s that are considered inconsistent with the real cost of health services. INA-CBGs tariff s are subject to regulations. reviewed at least every two years. The Government evaluates and revises the tariff s determined based on Unit cost (UC) calculations and takes into account various aspects. The results showed that in general UC calculation result with step down method for inpatient and outpatient service at 84 Public Hospital BLU / BLUD is lower than INA-CBGs Tariff . It can be concluded that the implementation of INA-CBG tariff s still meet the sense of justice and can be applied. It is recommended that the tariff review also takes into account the UC change and global / regional / national economic conditions so it should not be done every two years. On the other hand, hospitals need to manage INA-CBGs health services fi nancing effi ciently in order to maintain the quality of service and to meet the patients demand.

 

ABSTRAK

Berbagai komentar baik dukungan ataupun penolakan dilontarkan pihak rumah sakit (RS) sejak diberlakukan tarif INACBGs pada tahun 2014 dalam Jaminan Kesehatan Nasional (JKN). Sebagian RS mengeluhkan ketidak adilan besaran tarif yang dianggap tidak sesuai dengan biaya riil pelayanan kesehatan. Tarif INA-CBGs sesuai peraturan. ditinjau minimal setiap dua tahun. Pemerintah melakukan evaluasi dan revisi terhadap Tarif yang ditetapkan berdasar atas perhitungan Unit cost (UC) serta memperhitungkan berbagai aspek terkait. Hasil penelitian menunjukkan bahwa secara umum hasil perhitungan UC dengan metode step down untuk pelayanan rawat inap, dan rawat jalan di 84 RS Umum BLU/BLUD lebih rendah dari Tarif INA-CBGs. Dapat disimpulkan bahwa pemberlakuan tarif INA-CBG masih memenuhi rasa keadilan dan dapat diterapkan. Direkomendasikan agar peninjauan tarif disamping memperhitungkan perubahan UC juga kondisi ekonomi global/regional/nasional sehingga dapat dilakukan sesuai kebutuhan dan tidak harus dilakukan setiap dua tahun. Di pihak lain. RS perlu mengelola pembiayaan INA-CBGs untuk pelayanan kesehatan secara efi sien agar dapat menjaga mutu pelayanan sesuai harapan masyarakat.

The elderly are one of the most vulnerable groups with very high dependency rates. This condition has the potential to cause other problems for the caregiver or his family. The elderly also has the potential to suffer from catastrophic diseases that have costly consequences. This research is a further analysis of Riskesdas 2013 data, that presented in descriptive quantitative. The results showed that elderly people living in urban as well as rural areas have a tendency of moderate access barrier to Puskesmas. There are still 15% of very poor elderly people who have major access barrier to Puskesmas. This study concludes that although elderly access to Puskesmas is quite good, but the access of very poor elderly is still need more attention. The government needs to provide basic health care facilities in more rural areas. The government also needs to realize a National Health Insurance with tax-based funding, to ensure universal coverage regardless of the ability to pay the community.

Abstrak

Lansia adalah salah satu kelompok rentan yang memiliki angka ketergantungan sangat tinggi. Kondisi ini berpotensi menimbulkan masalah lain bagi yang merawat atau keluarganya. Lansia juga berpotensi menderita penyakit katastropik yang menimbulkan konsekuensi biaya yang mahal. Penelitian ini merupakan analisis lanjut data Riskesdas 2013, yang disajikan secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa lansia yang tinggal di perkotaan maupun perdesaan mempunyai kecenderungan hambatan akses sedang untuk ke Puskesmas. Masih ada 15% lansia sangat miskin yang memiliki hambatan besar ke Puskesmas. Penelitian ini menyimpulkan bahwa meski akses lansia ke Puskesmas sudah cukup baik, tetapi akses lansia yang sangat miskin masih perlu mendapat perhatian lebih. Pemerintah perlu menyediakan fasilitas pelayanan kesehatan dasar di wilayah perdesaan yang lebih banyak. Pemerintah juga perlu mewujudkan sebuah Jaminan Kesehatan Nasional dengan pendanaan berbasis pajak, untuk memastikan cakupan secara universal dengan tanpa menghiraukan kemampuan membayar masyarakat.
Den spirituelle vending - og den permanente undtagelsestilstand
Authors: Hjort Katrin
Published: May 2019

Den italienske jurist og politiske filosof Georgio Agamben taler om undtagelsestilstanden, hvor den suveræne, der er garant for sikkerhed - lov og ret - sætter lov og ret ud af kraft af hensyn til statens sikkerhed. Agamben taler om voldsomme begivenheder i det 20. århundredes historie. Han beskriver de lejre, hvor ekskluderede er blevet isoleret, og han viser, hvordan den retsløshed, der først gjaldt for nogle i nogen tid, kan blive permanent for alle altid. De tendenser, Agamben beskriver, ligner påfaldende noget, vi ser i Danmark i dag i forbindelse med det såkaldte paradigmeskift i migrations- og asylpolitikken. Ligheden er specielt tydelig i forbindelse med ghettoplanen og hjemsendelsesydelsen, men også i forbindelse med lejren Sjælsmark og øen Lindholm.  Som Ivan Krastev formulerer det, så erstattes den europæiske civilisations drøm om Utopia - frihed og demokrati - af drømmen om Nativia - det sted, hvor alle de forkerte og uønskede kan sendes hen. Denne dagdrøm – kan - som Ernst Bloch sagde - udnyttes politisk og polarisere samfundet, men også udgøre et håb, vi kan lære os at følge.
Engagementets tælling og fortælling: Et studie af brugen af medarbejderengagementsundersøgelser som dialogskabende og beslutnings-faciliterende præstationsmålingsinformation
Authors: Doktor Marc , Lennon Niels Joseph , Elmholdt Kaper Trolle
Published: May 2019

Måling af medarbejderengagement er en efterhånden udbredt praksis i mange virksomheder. Denne artikel undersøger og beskriver brugen af information fra medarbejderengagements (EE) modeller i organisationer, med henblik på at forbedre medarbejderengagement og organisationens præstation. Undersøgelsen er baseret på interviews med ledere fra organisationer, der bruger EE-undersøgelser og konsulenter, der leverer EE-undersøgelser. Undersøgelsen viser, at information fra medarbejderengagementsmodeller bruges som et resultatstyringsværktøj med det formål at 1) evaluere engagementets præstationer og 2) give nyttige oplysninger til beslutningstagning vedrørende forbedringer af medarbejderengagement. Begge dele understøtter formålet med at gennemføre medarbejderengagementsundersøgelser, som handler om at forbedre organisationens præstation gennem præstations-drivere. Hvor en del af litteraturen stiller sig kritisk overfor sådanne målinger og deres evne til at gøre engagementet tælleligt og generelt indfange de objekter, de påstår at repræsentere, hævder en anden del af litteraturen, at problemstillinger af en sådan karakter bør håndteres ved at forbedre det tekniske måleapparat.  Snarere end at be- eller afkræfte disse standpunkter argumenterer vi for, at det afgørende ligger i, hvorledes information om medarbejderengagement bruges for at opnå organisatoriske effekter af målingerne. I et forsøg på at bidrage konstruktivt til dette viser vi specifikt, hvordan en kontekstualisering af Armstrong (2000) 's præstationsledelsesmodel i forhold til mobilisering af medarbejderengagementsmålinger kan bruges til at strukturere måden, hvorpå organisationer kan skabe effekter af EE-informationer med henblik på at forbedre organisationens præstation.

Pest and disease are  limiting factors in red chili cultivation. Chili farmers often use synthetic pesticides to control pest and disease However, improper application of pesticide can cause deleterious effects to human and environment. The objective of research was to know the level of red chilli farmers understanding regarding pesticides use. This research was conducted in Bumijawa Subdistrict, Tegal District by interviewing farmers. A total number of 140 farmers were purposely selected and divided into 4 groups, namely integrated pest management (IPM) monoculture, non IPM monoculture, IPM multiple cropping, and non IPM multiple cropping. Data analysis was performed using cross tabulation for likert scale questionnaire and Rank Spearman to analyze the relation among variables. Results showed that all four farmer groups had similar characteristics, i.e age range of 20-65 years, dominance of elementary school graduates, and more than 10 years of farming experience. These group of farmers had positive  score  for  application and safety principle of pesticide but they still had negative score on ecological aspect. Farmer’s age, level of education, and farming experience did not affect the knowledge of non IPM monoculture and IPM monoculture groups. The level of education in non IPM multiple cropping group affected the application of pesticides. Farmer’s knowledge on pesticides usage and its safety application had significant correlation with farmer age and farming experience for IPM multiple cropping group.

Background/Aim. Measuring health-related quality of life is of great help to clinicians when they have to choose optimal therapy for their patients or estimate its effects. The aim of this study was to translate the oral health-related quality of life [OHQoL-UK(W)] questionnaire from English to Serbian, to make necessary cultural adaptations of the translation, and to test its reliability in a sample of adult Serbian patients. Methods. After obtaining permission from the authors, translation and cultural adaptation of the OHQoL- UK(W) was made according to the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines. Reliability of the Serbian translation was tested on a sample of 250 patients through calculation of Cronbach?s alpha, as a measure of internal consistency. Results. Serbian translation of the OHQoL-UK(W) had very similar degree of internal consistency (Cronbach?s alpha 0.947), and correlated satisfactorily with the visual analogue scale (VAS) score and inversely with the Decay-missingfilled teeth (DMFT) index. Factorial analysis revealed only one factor, as in the original scale. Conclusions. Serbian translation of the OHQoL-UK(W) is reliable instrument for measuring oral health-related quality of life in adult dentistry patients.
