Authors: Oliveira Fábio Corrêa Souza de
Published: December 2020

Este texto promove, a partir da circunstância brasileira, em especial na ambiência da pandemia, uma análise entre o que podemos denominar de reserva de governo e de reserva da ciência. A relação entre estes dois sistemas, que deveria ser harmoniosa, integrada, operacionalizada pelo Direito, manifesta-se, no Brasil, em um governo sem reservas, que tem o ímpeto de politizar a ciência, que reserva a ela a subjugação ou o exílio. Este impulso de colonização revela a crise institucional e simultaneamente testa a força das instituições, denotando também uma crise social, ambas a indicar que, aqui, a pandemia se espraia em meio ao pandemônio.

Published: December 2020

In this article, the focus is on understanding the awareness of sustainable design & product and health & safety among engineering and architectural students at university levels as these young graduates are representative of the workforce. This survey was conducted at five public universities in Peninsular Malaysia. On average, the majority of respondents provided positive responses (more than 80%) on the needs of sustainable design & product and health & safety aspects in their workplaces. These figures bode well for such an ambitious country to be on par with developed countries. It is also noteworthy to highlight that a significant portion who are not comfortable with investing with sustainable features.

Published: December 2020

This paper examines the influences of the built environment (distance between home and school) on the journey to school as a measure to promote active transportation to school. Data collected through a survey of 150 parents to represent Section 7 residents of Shah Alam, Selangor. This study shows that there is an insignificant relationship between school location and parents’ transportation mode choice. The most popular mode of transport chosen by parents was their private car compared to walking and cycling even though the distance from home to school was less than 800 meters because of a safety factor.
Keywords: school travel; active transportation; school location; safety.

We performed the calculations of the frequency-dependent polarizability of a hydrogen anion by using correlation-consistent basis sets with high diffuseness. The results obtained turned out to be close to the results obtained by the method of summation over pseudo-states. It is also shown that calculations by the density functional method do not allow obtaining high accuracy. This is due to the large size of anions compared to both cations and neutral atoms (molecules).

The linear-optical effect of the free polarization decay (FPD) in an ultrathin gas cell, the internal thickness of which is less than or of the order of the wavelength of the exciting monochromatic laser radiation, transmitted orthogonally to the plane-parallel walls of this cell, is theoretically investigated. The considered coherent FPD signal is emitted immediately after an abrupt interruption of such a relatively weak stationary radiation. Sub-Doppler resonances arising at the central frequencies of the studied quantum transitions in the spectra of the intensity and energy of the FPD as a result of the transit-time relaxation of atoms in the gas cell are established and analyzed. A significant dependence of these resonances and the dynamics of the FPD on the ratio of the inner thickness of the ultrathin cell to the wavelength of the exciting monochromatic radiation is shown. The narrow, high-contrast sub-Doppler resonances of the FPD detected and investigated in the linear-optical regime can be used in ultrahigh-resolution atomic (molecular) spectroscopy, as well as references for compact frequency standards.

Published: January 2021

In the approximation of slowly varying amplitudes, a system of coupled waves equations is obtained, which is applicable for describing the diffraction and coupling of elliptically polarized light waves on a volume phase-amplitude holographic grating formed in a cubic optically active photorefractive absorbing piezoelectric crystal. The dependence of the diffraction efficiency of the phase reflection hologram on the ellipticity of the readout wave and the thickness of the Bi12SiO20 crystal of the (001) and (111) cuts was studied. The regularities of the effect of circular dichroism on the diffraction efficiency of the phase reflection hologram are analyzed. It is shown that for crystal of (001)-cut the maximum diffraction efficiency of the reflection hologram depending on the crystal thickness can be achieved using a readout wave both with linear polarization and with elliptical polarization. For crystal of (111)-cut the highest diffraction efficiency is achieved using a linearly polarized readout wave. It has been established that the effect of circular dichroism on the intensity of the reconstructed wave depends on the cut of the crystal, the ellipticity of the readout wave and the thickness of the crystal.

Authors: Маймистов А.И.
Published: January 2021

Based on the quasi-classical description of electron dynamics in topological media, the gyrotropic prop-erties of which are due to the non-zero Berry curvature, the phenomenological model is proposed. Model allows us to consider some nonlinear optical processes – the generation of the third harmonic and the rotation of the wave polarization vector depending on the intensity. Third-order nonlinear sus-ceptibilities, which determine the interaction of waves taking into account the rotation of the wave po-larization vector, are determined. Gyrotropicity manifests itself in the dependence of the harmonic con-version efficiency on the circular polarization of radiation, which can be used to measure the parameters of this media.

The electron transitions property of the fullerene molecule is considered. Because of electron jumps between nearest neighbor is possible, the interaction of the $\pi$- electrons produces the appearance of the collective states, having truncated icosahedron symmetry. The irreducible representations of the icosahedral group allow us to subdivide the state functions into groups with separate energy sublevel. The good approximation of the wave functions for the irreducible representations developed by means of spherical functions superposition. The optical properties is presented by formula of the excitation cross-section for electronic levels and by formula of the spontaneous relaxation time, received with help of matrix element calculation. Because of Jahn–Teller effect, a time of non-radiative transition is much less than radiative relaxation time. The interaction with phonon spectrum produces the spontaneously broken symmetry and restricts electronic-emission spectrum, while the absorption in optical spectrum exists. Transfer of energy from electron states into phonon oscillations produces the thermal radiation. However, it is possible to solve problem of electron state decay.

The article considers the results of studies of the emission spectra of Ne and Ar upon excitation by pulsed laser radiation. We used Nd: YAG laser, λ = 1064 nm, τ = 5 ns, and Epulse = 0.8 J. The spectral range of 3-20 nm was studied. We used capillary and supersonic conical nozzles with dcr = 145 μm, 2α = 12o, L = 5 mm, and dcr = 450 μm, 2α = 11o, L = 5 mm to form an atomic cluster beam. The emission spectra for various gas targets were obtained, the obtained spectra were deciphered, and the ions emitting in this spectral range were determined. We observed that with increasing particle concentration in the zone of laser spark, the radiation intensity increases. In this case, the intensity of ion lines with high degrees of ionization increases faster.

In the semiclassical approximation, the density of the electron energy spectrum near the metal surface is described, when electron is bound by the image field and the blocking electrostatic field. In the system under consideration, the confinement mechanism is realized, and the energy spectrum for the motion of an electron in the direction perpendicular to the metal surface is completely discrete. The density of states of the energy spectrum is expressed in terms of elliptic integrals, the argument of which is a sigmoidal function. When the field is turned off, it becomes the Heaviside step function. A dimensionless energy parameter is introduced, which determines the intervals with qualitatively different changes in the width of the classically accessible region of motion. For large positive values of the energy parameter, the spectrum density asymptotically tends to the density in the triangular potential with the addition of the Coulomb logarithmic correction, and for negative values of the energy parameter, the spectrum density tends to dependence for a one-dimensional Coulomb potential. Approximate expressions are obtained for the spectrum density in terms of elementary functions in a wide range of electron energies and electric field strength.

The temperature, spectral and pressure dependences of the birefringence Δni of potassium sulfate crystals doped with 1.7% of copper have been studied. The introduction of the impurity is found to change the absolute value of Δni and lead to an increase in the temperature dependence of Δnі(Т). It is shown that the isotropic points appear in the doped crystal of potassium sulfate, and are shifted, compared with a pure crystal, towards low temperatures by 5 K and 11 K, respectively. It was established, that uniaxial stresses change the magnitude of the Δni absolute values, as well as the region of existence of the isotropic state. Generalized temperature-spectral-baric diagrams of the isotropic state of doped potassium sulfate crystal are constructed, making it possible to use them as a crystal-optical sensor.

The main purpose of this work was to carry out a low-temperature synthesis of glass ceramics containing YNbO4:Eu3+ crystallites and to study the structural and luminescent properties of the obtained samples. Within the framework of this work, the inclusions that crystallized under the conditions of low-temperature synthesis in the systems of SiO2-Na2O-K2O-Y2O3-Nb2O5-Eu2O3 (SiNaK) and B2O5-Na2O-Y2O3-Nb2O5-Eu2O3 (BNa) were investigated for the first time. It was shown that YNbO4: Eu3+ crystallized in both considered systems. In the SiNaK system the crystallization of SiO2 also occurred (quartz, crisstabolite, and tridymite) under the selected conditions. The BNa system proved to be the most promising for the synthesis of activated glass-ceramics with YNbO4, since the required crystallites crystallized only in ithis system. The luminescent properties of crystalline inclusions were investigated using the local cathodoluminescence technique. The composition and structure of glass ceramics were studied by electron-probe microanalysis and X-ray diffraction phase analysis.

The spectra of light reflection by plasmonic metal films deposited in vacuum on dielectric substrates and subsequently annealed at high temperatures are investigated. To explain the optical properties of plasmonic films, a theoretical model of a flat-layered metal-dielectric medium is used. One of the layers of such a structure has the dielectric constant of the metal under study, and the second layer has the dielectric constant calculated within the Maxwell-Garnett approximation for a heterogeneous medium consisting of a suspension of metallic nanoellipsoids in air. The introduction of this layer makes it possible to qualitatively take into account the inhomogeneities of the plasmonic film surface. It is shown that the developed model makes it possible to explain a number of features in the experimental reflection spectra

A new approach to derive symmetrized expressions of leading classical moments of spectral distributions characterizing different anisotropic terms of the interaction potential for the case of two liear molecules is presented. The results allow to calculate diffuse shapes formed by transitions between continuous eigenstates of a molecular pair and open the way to account for the nonMarkov effects (due to finite collision durations) in the rotatonal relaxation matrix of an arbitrary rank. The approach is also applied to the spectral moments of vector and tensor characteristics determining the band intensities in the collision-induced spectra of linear molecules. Generally, the use of symmetrized expressions lead to considerably faster computer codes.

The possibility of identification and counting of native donor blood erythrocytes based by static, non-flow digital optical microscopy was studied. The object of study was the whole donor blood diluted by saline and placed into Goryaev's counting chamber. The sample was examined in transmitted light by a Lumam P-8 digital optical microscope equipped by a Basler acA920-40um camera. In order to identify erythrocytes by spectral characteristics two sets of micrographs of 20 pieces in each were obtained. In the first set there was no optical filter in the illumination channel of the microscope and in the second set an interference filter for a 420 nm wavelength with a 10 nm bandwidth was used. The characteristics of the interference filter were chosen to come more close to the Soret band of the RBC hemoglobin to obtain the best contrast for photographic images. The technique for automated analysis of micrographs using the OpenCV software was developed to recognize erythrocytes and to carry out their counting. The results of the computer RBC counting were compared with the manually counted red blood cells. It was found that for computer approach accepted the proportion of the erythrocytes identified and counted in averages was 97-98%.

Published: January 2021

In this paper, we have used the double exposure digital holographic interferometry (DEDHI) technique to determine the diffusion coefficient of urea in pure distilled water at 27oC (room temperature) and it is used further to predict urea movement in soil by considering the concentration of urea solution and diffusion coefficient to study early plant growth. We have recorded several consecutive digital holograms of diffusing solutions of urea and pure distilled water at different times instantaneously on the CCD chip and processed them with H-Digital numerical reconstruction software on the computer. It is observed that as the concentration of urea solution increases from 0 to 4 M, diffusion coefficient 'D' of urea slightly increases from 12.2 to 13.8 × 10^-6 cm^2/s, which considerably affects the growth of the plants.

The accumulation of sediment in the harbors hinders the easy movement of boats. To avoid this, dredging operations are carried out regularly to restore correct functioning but also to present water quality managing the huge amount of dredged sediments and recycling them into building materials is a major challenge for the treatment of these sediments. It is within this framework that we propose to use the Laser Induced Breakdown Spectroscopy (LIBS) as a promising new technique for measuring trace metal concentrations of marine sediment samples. Our work has focused on the effect of granulometry on the relative concentration of inorganic compounds. The Principal Component Analysis (PCA) discriminated between different sediment clustering them into three groups: G1 (1.25mm-75 μm), G2 (75 μm-50 μm) and G3 (< 50 μm). Significant differences between element concentrations in the three groups, corroborating published works, were observed and concentrations in each group are reported in this study.

Published: December 2020

Background

Optimization of innovative approaches is required for estimating the intimate partner violence (IPV) burden among adolescents and young adults (AYA). Further investigation is required to identify risk and protective factors associated with IPV among AYA. There remain significant gaps in understanding these factors among this vulnerable population.

Objective

The goal of our study was to determine the prevalence of IPV among an urban population of AYA and to identify factors associated with IPV among AYA.

Methods

A cross-sectional study design utilizing respondent-driven sampling was adopted. The study was conducted among 887 AYA, aged 15 to 24 years, residing in Nairobi, Kenya. Data were collected through a phone-based survey using the REACH (Reaching, Engaging Adolescents and Young Adults for Care Continuum in Health)-AYA app. Questions on behavioral and psychosocial factors were adopted from different standardized questionnaires. Descriptive, bivariate, and multivariable statistics were used to describe the characteristics of the study sample.

Results

Of the 887 participants, a higher proportion were male (540/887, 60.9%) compared to female (347/887, 39.1%). The prevalence of IPV was 22.3% (124/556). IPV was associated with being unsure if it was okay for a boy to hit his girlfriend, living in a home with physical violence or abuse, and being bullied (P=.005). The likelihood of experiencing IPV was higher among respondents whose friends and family members used alcohol (odds ratio [OR] 1.80, 95% CI 1.09-2.98) and among those who had repeated a class at school in the past two years (OR 1.90, 95% CI 1.11-3.23). Respondents who visited a health facility or doctor for reproductive health services were 2 times more likely to experience IPV (OR 2.23, 95% CI 1.40-3.70). Respondents who had used illicit drugs were 2 times more likely to experience IPV (OR 4.31, 95% CI 2.64-7.04). The probability of experiencing IPV decreased by 63% (OR 0.37, 95% CI 0.16-0.85) among respondents who refused to have sex with someone who was not prepared to use a condom.

Conclusions

IPV remains a significant public health priority because of its impact to society. Our results are in congruence with other similar studies. Efforts toward incorporating appropriate IPV core measures into the comprehensive care package for every AYA seeking health services should be explored. Programs need to address constellations of risk and protective factors linked to IPV in an effort to prevent its occurrence.

The issues of minorities still become an interesting topic to be discussed since practically the laws sometimes cannot protect the rights of the minorities. Homosexuals are one of the minority groups in the United States struggling with homophobia. The existence of gay conversion therapy is a paradox in the multicultural country. This research is conducted to examine how the portrayal of homophobia in gay conversion therapy and how the paradox of multiculturalism depicted in Conley’s memoir entitled Boy Erased. The primary data of this research are the dialog and narration in the memoirpublished in 2016,which contains the irony behind the existence of gay conversion therapy. The secondary data are taken from articles and current news that relates to the issues. The post-nationalism approach, homophobia theory, and multiculturalism theory are used to analyze the data. The study found institutionalized homophobia at Love in Action (LIA) as the gay conversion therapy institution. The reasons behind the existence of gay conversion therapy are the paradox of toleration, lack of equal recognition, and the inability to provide positive accommodation for homosexuals. The existence of gay conversion therapy proved that the struggles of homosexuals in the United States still need to be overcome.
RESHAPING THE HOMOSEXUAL IDENTITY OF MIDDLE-AGED GAY MEN IN AMERICA: A SOCIOLOGICAL STUDY OF IDENTITY PROCESS ON ANDREW SEAN GREER’S LESS
Authors: Su'da Fairuz , Rokhman Muh Arif
Published: December 2020

The detrimental effects caused by the LGBT victimization in America are directly felt by middle-aged homosexuals nowadays and is internalized into their identity, creating problems that continuously affect them even after LGBT acceptance in the United States. The shift of homosexual identity in middle-aged American homosexuals is thus inevitable in order to regain their identity balance. Andrew Sean Greer’s Less depicts this issue through the internal conflicts of Arthur Less —a character struggling to accept his identity as an aging homosexual man. Arthur’s process in assimilating new experiences around him and accommodating his conceptionabout his homosexual identity become the highlights of this study. The writer utilizes Susan Krauss Whitbourne’s Identity Process Theory that deals with identity assimilation, identity accommodation, and identity balance. The result shows that past LGBT victimization has caused (1) HIV/AIDS trauma, (2) hyper-sexualized image, (3) cynicism towards marriage, and (4) internalized homonegativity, all of which creating the balance disruption on identity. When identity assimilation fails and identity accommodation occurs, middle-aged American homosexuals are encouraged to acknowledge that (1) homosexual identity exists beyond stereotyped sexual context, (2) there are no standardized attitudes that they must adopt, and (3) they are allowed to desire the same sense of comfort and intimacy through committed relationship or marriage, like their heterosexual counterparts.

Objective: The present work deals with the development and validation of the absorbance ratio method for the estimation of rosuvastatin calcium and fenofibrate in bulk and pharmaceutical formulation. Studied forced degradation characteristics of bulk and pharmaceutical formulation as per stability guidelines.
Methods: The bulk and pharmaceutical formulation studied by the absorbance ratio method. It is the ratio of absorbances at two selected wavelengths. One wavelength is the isoabsorptive point and another wavelength is λ max of one of the components. From the overlay spectra of the two drugs, ROS and FEN showed the isoabsorptive point at 249.5 nm. The second wavelength used was 287 nm, which was the λ max of FEN.
Results: The drugs obeyed Beer's law and showed a good correlation. The correlation coefficient for the ROS was 0.999 and for FEN 0.999. The RSD for intraday precision was 0.57 for ROS and 0.057 for FEN. The interday precision was 0.05 for ROS and 0.03for FEN, respectively. The detection limit and quantification limit were found to be 0.048 and 0.14 μg/ml for ROS and 0.069 and 0.21μg/ml for FEN, respectively. More degradation was found in acid hydrolysis and photostability degradation.
Conclusion: A simple, precise, accurate, validated, stability-indicating method for simultaneous estimation of rosuvastatin calcium and fenofibrate in bulk and pharmaceutical formulation has been developed.

The problem of ineffective and inefficient rehabilitation of inmates as well as in reducing their high rates of unprecedented unwholesome behaviors informed this study. Two research questions were answered and two hypotheses were tested. The study was a quasi-experimental study that adopts pre-test and posttest control group design. The treatment session lasted for a period of 12 weeks representing 24 sessions. The study was able to identify 35 inmates with depressive tendencies and suicidal ideation. Out of the 35 consent forms distributed to 35 inmates with depressive tendencies and suicidal ideation, 20 consent forms were returned showing interest in the study. Beck Scale for Suicide Ideation (BSS) developed in 1991 with a self-report of 21 items was used for data collection with reliability ranging from α = .87 to α = .89 across samples. The Center for Epidemiology Study Depression Scale (CES-D) with 20items developed by Radloff (1977) was used to measure depression of any population of people. The internal consistency reliability coefficient of 0.88 was computed for CES-D through Cronbach Alpha statistics. Mean and standard deviation were used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the null hypotheses at 0.05 level of significance. It was found that Rational Emotive Behavior Therapy (REBT) significantly improved the management of suicidal ideation and depressive tendency among inmates in correctional centers. It was concluded that REBT has been found to be significant in handling behaviuoral problems as well as in improving the management of suicidal ideation and depressive tendency among inmates in correctional centers. It was recommended that inmates should be given close monitoring by their supervisors and warders in order to emancipate them from self defeating perception, thoughts and feeling that could endanger their emotion. Counseling-psychologists and religious leaders should make it a point of duty to be rekindling hope freedom, future and belongingness.

The aim of this study, which is taking place in the territorial jurisdiction of the Inspectorate of Preschool and Primary Education (IEPP) of Bouake d'Air-France, is to assess the link between perceptions of teacher function among teachers and their motivation. The premise behind the study is that perceptions influence teacher motivation. The theoretical anchor of this study is the theory of reasoned action of Ajzen (1991). To test this hypothesis, a sample of 86 teachers was randomly selected and represent 20% of the total number of teachers estimated at 432. The information-gathering techniques are: the documentary research, the questionnaire, consisting of 11 items to be informed and the inventory of motivations at work (EMT-31). The data collected was processed using Excel software. The main findings reveal that teachers have negatively dominant perceptions of their profession and are almost motivated. In addition, a link between "negative perception" and "a-motivation" has been established, although this link is not too strong in relation to the phi contingency coefficient (0.22).
NIA 701- EXPERIENCIAS EN ESPAÑA Y REINO UNIDO: DESAFÍOS PARA LOS AUDITORES INDEPENDIENTES EN CHILE
Authors: Navarrete Esparza Marcelo , Ruiz Cifuentes Juan Carlos , Escalona Pradenas Rodrigo
Published: December 2020

La presente investigación analiza la experiencia de divulgación de asuntos claves de auditoría (en adelante, ACA) bajo la norma internacional de auditoría NIA (701) aprobada en Europa el 1° de enero 2015 por el Consejo Internacional de Normas de Auditoría y Aseguramiento (IAASB). La metodología es descriptiva sobre el contenido de una muestra por conveniencia de 94 ACA en España y 160 ACA en Reino Unido para los períodos 2017 y 2018. El carácter exploratorio se debe a que es un fenómeno poco estudiado en Chile, y es longitudinal porqueconsidera el análisis de información de dos períodos consecutivos. El resultado de esta investigación muestra una tendencia en ambos países de mayor comunicación de ACA en la industria de manufactura. En España por ejemplo, el ACA “Deterioro de Valor” es divulgado mayoritariamente en la industria de manufactura, mientras que en Reino Unido el ACA fue “Provisiones, pasivos contingentes y otras provisiones contables”, para las industrias de Retail (primer lugar) y de Transporte (segundo lugar). Dado este estudio, es previsible quelos auditores independientes en Chile tenderán a informar los mismos conceptos de riesgos significativos ACA en estructuras de industrias similares y/o iguales, conforme ha sido la experiencia en Europa.

Perpustakaan Digital adalah suatu perpustkaan yang memanfaatkan teknologi informasi untuk pengelolaan koleksi pustaka ataupun setiap kegiatan perpustakaan. Digitalisasi perpustakaan merupakan suatau keharusan bagi setiap Perguruan Tinggi karena hal tersebut dijelaskan pada Pasal 24 Ayat (3) UU Nomor 43 Tahun 2007. Selain itu perpustakaan digital juga diperlukan ketika Perguruan Tinggi melaksanakan akreditasi Perguruan Tinggi. Namun pada STMIK Primakara, sistem perpustakaan digital yang ada belum mampu memenuhi seluruh data seperti statistik kunjungan yang diperlukan pada saat akreditasi. Untuk mengatasi masalah tersebut, maka dibangun sistem yang dapat mendukung hal tersebut. Penelitian ini menggunakan metode Personal Extreme Programming (PXP) serta menggunakan Framework CodeIgniter sebagai pondasi sistem dan pada uji efektivitas sistem menggunakan metode McLean and DeLone. Penelitian ini berhasil membangun dan mengimplementasikan sistem perpustakaan digital yang telah dirancang.  Dari hasil uji efektivitas sistem yang dilakukan dengan menyebar kuisioner kepada mahasiswa STMIK Primakara, dapat dikatakan bahwa  sistem yang telah dibangun mendapatkan hasil yang sudah cukup baik pada hampir tiap variabel uji efektivitasnya
Implementasi Kebijakan Anggaran Pengembangan Kompetensi Sumber Daya Aparatur di Pemerintahan Provinsi Jambi
Authors: Dianto M
Published: December 2020

Penelitian ini dilatarbelakangi keinginan untuk mengetahui sejauhmana implementasi kebijakan anggaran pengembangan kompetensi aparatur di Lingkungan Pemerintah Provinsi Jambi.  Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang mempengaruhi implementasi kebijakan anggaran pengembangan kompetensi aparatur oleh para Kepala Organisasi Perangkat Daerah (OPD) yang memiliki tanggungjawab untuk mengelola kebijakan teknis, program dan kegiatan pada masing-masing OPD.. Penelitian ini berbasiskan teori implementasi George C Edward III yang menyatakan bahwa implementasi dipengaruhi oleh empat variabel, yakni komunikasi, sumber daya, disposisi dan struktur birokrasi. Metode yang digunakan dalam penelitian ini ialah menggunakan metode kuantitatif dan kualitatif secara bersamaan dengan data primer dan sekunder yang diperoleh melalui wawancara mendalam, observasi dan studi dokumentasi. Informan ditentukan dengan purposive sampling, yakni para Kepala OPD. Triangulasi data dilakukan dengan metode triangulasi sumber. Hasil penelitian ini menunjukan bahwa implementasi kebijakan anggaran pengembangan kompetensi  aparatur di Lingkungan Pemerintah Provinsi Jambi belum optimal hal ini ditandai dengan tersumbatnya komunikasi dimana tidak adanya transmisi komunikasi yang diterima Kepala OPD terhadap aturan anggaran 0,34% APBD dipergunakan untuk pengembangan kompetensi aparatur. Selain itu, belum optimalnya implementasi juga disebabkan hampir sebagian besar OPD memiliki anggaran pengembangan kompetensi aparatur dibawah 0,34%. Dampak dari tidak optimalnya kebijakan anggaran pengembangan kompetensi aparatur adalah hanya sekitar 15% PNS di provinsi ini yang memiliki kesempatan untuk memperoleh pelatihan pengembangan kompetensinya.  Walaupun demikan, kabar baiknya adalah para Kepala OPD sepakat menyatakan bahwa perlu diberi ruang bagi aparatur untuk mengembangkan kompetensinya dan mereka berjanji untuk meningkatkan anggaran pengembangan kompetensi aparatur minimal sesuai peraturan perundang-undangan yang berlaku.
