Authors: Yegen Baki
Published: March 2019

Vergi alacaklısı olan devlet ile borçlu konumunda olan birey arasında vergileme
ilişkisi ile ilgili olarak zaman zaman anlaşmazlıklar yaşanmaktadır. Söz konusu
anlaşmazlıklar literatürde vergi uyuşmazlığı olarak ifade edilmektedir. Vergi
uyuşmazlıkları idare tarafından hesaplanan ödenecek vergi miktarı konusunda
olabileceği gibi mükelleflerin vergi kanunlarına aykırı hareket etmeleri
neticesinde aldıkları cezalar konusunda da olabilmektedir. Cezalar eylem
türlerine göre idare tarafından ya da adli merci tarafından verilmektedir.
Verilen cezalarla ilgili yaşanan uyuşmazlıklarda mükelleflere kanun yollarına
gidebilme hakkı tanınmaktadır. Bu kapsamda mükelleflerin takip edebilecekleri
kanun yolları benzerlik göstermesine rağmen yargı organları ve çözüm süreçleri
farklılık göstermektedir.

The Comparison of the Quality Properties of Some Commercial Cold Pressed Seed Oils
Authors: ÖZYURT Hazal
Published: March 2019

In this study, it is aimed to
define the properties which determine their effects on the quality and health
of five different kinds of seed oils produced by the cold pressed extraction
method. The cold pressed seed oils known as coffee bean, pomegranate, cherry,
apricot, and fig kernels which are produced in the domestic market of Turkey
were bought to determine the quality characteristics such as peroxide values,
free fatty acidity, and UV-specific absorption values, total phenolic compounds
and antioxidant activity of these seed oils. When the peroxide values were
examined, the highest peroxide value was found in coffee bean oil and the
lowest peroxide value was found in pomegranate seed oil. When the free fatty
acidity is considered, the number of free fatty acids is ranked from the
highest to the lowest as coffee bean oil, fig kernel oil, sour cherry seed oil,
pomegranate seed oil, and apricot kernel oil. The K232 value was
found to be the highest in coffee bean oil while it was the lowest in apricot
kernel oil. K270 values were the highest in pomegranate seed and the
lowest in the apricot kernel. As seen in the results of the total phenolic
compound analysis performed to recognize the effects on health, this value was
highest in coffee bean oil, followed by apricot kernel oil, fig kernel oil,
pomegranate seed oil, and sour cherry seed oil. When the results antioxidant
activity analysis were examined, the antioxidant activity of apricot kernel oil
was found to be the lowest, while this value of fig kernel oil was found to be
the highest. According to the analysis of variance, these differences were
statistically found to be significant. In addition, these values were compared
with the studies in the literature and evaluated according to the legal limits.
These products sold on the grounds that they have beneficial effects on health
in the market should be implemented with more stringent procedures to be
audited by public institutions and legal regulations should be supported by
further scientific studies.

Authors: Ponomarev B.B. , Hien Nguyen Sy
Published: March 2019

This article presents the results of single-factor modeling and analysis of the influence of tool orientation with regard to the tilt angle and lead angle, on cutting forces when finish milling by a ball end cutter. The program NX 10 is used to build boundaries and contact areas of the tool and the workpiece, and the SIMULIA ABAQUS software is used to create a three-dimensional finite element model and determine the cutting forces. Graphs that describe dependencies of the cutting forces on the tool rotation angle are obtained for different orientations of the tool axis relative to the surface normal. The computational results will allow transition to the two-factor analysis of the influence of tilt angle combinations on the cutting forces and the determination of the optimal tool orientation during five-axis milling with maximum productivity.

Authors: Volkov S.S. , Korolev S.A. , Shestel L.A.
Published: March 2019

The specifics of ultrasonic planimetric welding of polyethylene containers of irregular shape filled with foodstuff are considered in this work. A planimetric wave guide that can be used for welding polyethylene containers of a large diameter (up to 120 mm) and thickness ranging from 0.4 to 1.5 mm is proposed and implemented. The issue of obtaining high-quality leak-tight weld joints with stable mechanical properties on the surface of a polyethylene container exposed to corrosive environment is resolved. Various shapes of the working surface of the planimetric wave guide are developed, making it possible to weld containers with good appearance, durability and leak-tightness. A scheme for welding containers by a planimetric wave guide with an acoustic screen is proposed. The results of studies to determine the optimal parameters for the modes of ultrasonic planimetric welding are presented. The shape, material and position of the support in relation to the planimetric wave guide are defined. The technology and equipment for ultrasonic planimetric welding of polyethylene cans of a large diameter filled with various substances and foodstuff are developed. As the result of the research, all the studied liquids are divided into three groups depending on their influence on weldability.

Przesłanki orzekania izolacji postpenalnej rozważania na tle orzecznictwa sądów powszechnych i Sądu Najwyższego
Authors: Jędras Franciszek , Grabarczyk Katarzyna
Published: March 2019

Przedmiotowa ustawa wprowadziła do polskiego porządku prawnego instytucję izolacji postpenalnej. Regulacja ta jeszcze na etapie prac legislacyjnych była szeroko krytykowana przez środowiska naukowe jako wprowadzona pospiesznie i w sposób nieprzemyślany. Zarzucano jej, że stanowiła jedynie odpowiedź na społeczne zapotrzebowanie, wynikające z obawy przed opuszczeniem zakładów karnych przez sprawców najcięższych przestępstw, którzy kończyli odbywanie kary 25 lat pozbawienia wolności. Wątpliwości doktryny koncentrowały się wokół sposobu określenia zakresu podmiotowego ustawy. Wskazywano, że jest on nieprecyzyjny i budzi zasadnicze wątpliwości interpretacyjne, co skutkować może odnoszeniem jej postanowień do zbyt szerokiego kręgu adresatów. Analiza orzecznictwa sądów powszechnych i Sądu Najwyższego wskazuje jednak, że regulacja stosowana jest z ostrożnością, a sądy wykorzystują istniejące możliwości procesowe, wynikające z trybu nieprocesowego postępowania cywilnego w celu zapobiegania nieuprawnionej ingerencji w wolność człowieka oraz jego status jako podmiotu prawa.

The scale levels identification for the plowland topography organization
Authors: Minayev N. V. , Nikitin A. A. , Kozlov D. N.
Published: March 2019

The identification of factor and indicational features, which are characterized by the high informativity and field of view in relation to the soil cover organization, plays a very important role in the soil mapping. Such characteristics are more common for Unmanned Aerial Vehicles (UAV), which include spectrazonal imagery and digital elevation model (DEM) with ultrahigh spatial resolution, necessary for obtaining fine and large scale images. However, the agrogenic micro- and nanotopography is considered as a noise during the studies of the soil cover topographic differentiation under the conditions of plowland, as the genetic soil properties correlate with natural micro- and mesotopography. A filtration algorithm for the land surface roughness, which is not related to the spatial organization of the objective soil properties, is suggested in the paper. The stages of linear dimension identification for self-similar structures of the glacial and agrogenic topography based on two-dimensional Fourier decomposition are demonstrated using the example of a field topography digital model for the area of 125 hectares. Filtering in the frequency domain allowed restoring the natural field topography and substantiating the effective resolution of the DEM and the size of the area to calculate local morphometric specificities of the topography for digital soil mapping.

Authors: Hakim Ahmad Tsaqib , Dewi Arrum Prima , Perdana Doan , Kurnaman Cyril Nugrahutama
Published: March 2019

For decades, there have been significant interests in monitoring the aquatic environment for scientific exploration, commercial exploitation, coastline protection, and even disasters prevention and mitigation such as tsunami warnings. Highly precise, real-time, and temporal-spatial continuous aquatic environment monitoring system is extremely important for underwater life. To support and simulate such monitoring system, underwater sensor networks (UWSN) have emerged as a very powerful technique for many applications on underwater environment, including monitoring, measurement, surveillance, and control by using Aqua-Sim. Aqua-Sim is a simulator for UWSN developed on Network Simulator 2 platform which effectively simulates the attenuation of underwater acoustic channels and the collision behaviors in long delay acoustic networks. Currently, there are several routing protocols for UWSN which are implemented in Aqua-Sim. On this research, we did a simulation on Aqua-Sim by performing Vector-based Forwarding (VBF) protocol and Depth-based Routing (DBR) protocol performance analysis based on energy consumption parameter. Based on the result, it can be concluded that the VBF routing protocol requires more energy consumption than the DBR routing protocol.

Authors: Brazão José Paulo , Mendonça Alice Maria
Published: March 2019

Conceitualizar a Arte pressupõe aceder aos múltiplos significados que a linguagem escrita lhes atribui e ainda às perceções pessoais de quem o faz. Por isso, neste estudo de caso propusemo-nos determinar as representações de Arte dos estudantes de dois cursos profissionalizantes da Universidade da Madeira (Mestrados em Ensino de Educação Física e em Educação Pré-Escolar e Ensino do 1º Ciclo do Ensino Básico[1]). Através da pesquisa bibliográfica e da aplicação de inquéritos por questionário identificámos as representações dos estudantes acerca de Arte. A triangulação de dados envolveu uma abordagem metodológica simultaneamente qualitativa e quantitativa. As conclusões permitiram-nos compreender que a formação inicial condiciona as representações dos estudantes acerca de Arte. Embora ambos os grupos a valorizem, a sua representação e aplicação profissional desenham-se de acordo com as áreas curriculares já estudadas.[1] O Mestrado em Educação Pré-Escolar e Ensino do 1º Ciclo do Ensino Básico é a grau de mestre necessário para, em Portugal, ser professor do Ensino Fundamental.

Published: March 2019

Objetivou-se avaliar o efeito da adição do farelo de babaçu na composição química e características fermentativas de silagens de cana-de-açúcar. Foram avaliadas três concentrações de adição do farelo de babaçu (0; 15 e 30% na matéria natural) em um delineamento inteiramente casualizado com quatro repetições cada. Como silos experimentais foram utilizados 12 baldes plásticos, providos de torneira de filtro para permitir a saída dos gases produzidos durante a fermentação. Os silos foram abertos com 45 dias de ensilagem e amostras foram colhidas para determinação dos teores de matéria seca (MS), de proteína bruta (PB), de fibra em detergente neutro e ácido (FDN e FDA), de hemicelulose (Hem), valores de pH, acidez total titulável (ATT), perdas por gases (PG) e por efluentes (PE). A adição de farelo de babaçu elevou os teores de MS (38,4% e 40,6%), de PB (7,8 e 8,9%), de FDN (68,8% e 70,9%) e de FDA (43,0% e 45,1%), respectivamente com a adição de 15 e 30% de subproduto. O pH não foi influenciado pela adição do farelo de babaçu, apresentando valor médio de 4,4. Já os percentuais de ATT foram elevados em 89,2%. Por sua vez as PG e PE foram reduzidas em 44,8 e 58,8%, respectivamente. Apesar da adição do farelo de babaçu ter contribuído para a melhoria dos parâmetros fermentativos e da concentração de PB das silagens de cana-de-açúcar, a utilização do mesmo como aditivo torna-se limitada devido ao aumento dos teores de fibra que esse subproduto proporciona às silagens, depreciando valor nutritivo das mesmas.

Published: March 2019

Foi avaliado o efeito da adição de cultura de leveduras vivas (Saccharomyces cerevisiae, cepa 1026), da monensina e da combinação dos dois aditivos em dietas de alto concentrado, sobre as características de desempenho de novilhos confinados e sobre a digestibilidade aparente da dieta. Novilhos Nelore (339 kg PV, 20 meses de idade, n= 72) foram alimentados por 84 dias com uma dieta basal (2,58 Mcal EM/kg MS, 14% PB) sem aditivos (controle) ou suplementada com levedura (0,6 g de Beef Sacc®/kg de matéria seca), monensina (0,3 g de Rumensin®/kg de matéria seca) ou a adição de ambos aditivos para avaliar o desempenho em confinamento por meio da mensuração individual do consumo, ganho de peso e medidas de ultra-som da espessura de gordura subcutânea nos músculos Longissimus (12ª costela) e Biceps femoris. Outros quatro novilhos foram designados aleatoriamente aos tratamentos seguindo um delineamento em quadrado latino a fim de determinar os efeitos dos tratamentos sobre a digestibilidade aparente da matéria seca, proteína bruta, fibra em detergente neutro e ácido da dieta. Não houve efeitos dos aditivos sobre o consumo de matéria seca e na taxa de aumento da espessura de gordura subcutânea e em área do músculo Longissimus, entretanto, a levedura tendeu a diminuir o ganho de peso médio diário e aumentar a conversão alimentar (p0,10). A adição de leveduras vivas, monensina ou da combinação de ambos pode não ser importante sobre a terminação de bovinos de corte confinados com dieta de alto concentrado.

Published: March 2019

El objetivo del presente trabajo fue caracterizar las relaciones entre la altura a la cadera como indicador de tamaño corporal, con diferentes indicadores productivos y reproductivos en vacas lecheras mantenidas sobre pasturas en un intento por identificar biotipos con diferente aptitud en este tipo de sistemas. Se compararon vacas Holstein de tercera lactancia, de distinto tamaño corporal, que conviven en sistemas a pastoreo. Se analizaron variables productivas y reproductivas para los distintos tamaños. No se observaron diferencias estadísticamente significativas (p>0,05) entre las vacas de mayor tamaño y las de menor tamaño en las variables reproductivas y en los indicadores productivos estudiados. Los resultados indican que la altura no incide en los niveles productivos ni en los reproductivos. Se identificaron cuatro biotipos y se constata que para el sistema de producción de leche en la región de la pampa húmeda de la República Argentina, el más eficiente es el de vacas con menor altura y producción de leche media.

O experimento foi desenvolvido objetivando-se avaliar o efeito da inoculação de estirpes de Streptococcus bovis (HC5 e JB1) sobre o pH, a produção de amônia e o valor nutricional em silagens de capim-elefante (Pennisetum purpureum Schum). O delineamento experimental foi o inteiramente casualizado, com três tratamentos: T1 - capim-elefante, T2 - capim-elefante inoculado com Streptococcus bovis HC5 e T3 - capim-elefante inoculado com Streptococcus bovis JB1, utilizando cinco repetições por tratamento. A menor concentração de amônia foi observada na silagem tratada com inoculante à base Streptococcus bovis JB1 (5,90 p.100 N-total). A inoculação aumentou os teores de ácido láctico e diminuiu os teores de ácidos acético, butírico e propiônico, sendo que as silagens inoculada com Streptococcus bovis JB1 e HC5 foram os que apresentaram os maiores valores de ácido láctico. Não houve diferença estatística para os teores de MS e PB. Para os valores das fibras, a silagem de capim-elefante inoculada com Streptococcus bovis JB1 apresentou o menor valor de FDN (59,77 p.100) e HEM (26,71 p.100). O maior valor da DIVMS foi observado na silagem com Streptococcus bovis JB1, mostrando superioridade de quatro pontos percentuais (64,23 p.100) em relação ao tratamento sem inoculante bacteriano (60,35 p.100). O uso Streptococcus bovis JB1 melhora o processo fermentativo além de promover melhorarias na qualidade da fibra e na DIVMS da silagem estudada.

Published: March 2019

Con el propósito de estudiar la conformación corporal de ovinos Blackbelly, se tomó una muestra aleatoria de 220 hembras y 36 machos de los rebaños del municipio de Campeche, México. La zoometría fue la base del estudio y se evaluó con 14 medidas corporales y el peso vivo de ovinos de uno, dos y tres años de edad. Se efectuaron análisis de varianza y de correlación, así como un análisis de conglomerados en los machos y hembras de uno y tres años de edad. Las medidas corporales tuvieron cambios significativos (p£0,05) hasta los tres años edad. Las diferencias entre hembras y machos fueron más grandes después de un año de edad, sobre todo en el peso vivo. Todas las mediciones se correlacionaron significativamente (p£0,01), particularmente el peso vivo con el perímetro torácico, con la altura a la cruz, y con el perímetro testicular. Los animales de un año de edad mostraron una variabilidad corporal considerable; una parte de ellos tenía valores zoométricos muy cercanos a los límites máximos estimados en el grupo de tres años de edad. Por sus patrones corporales en la etapa adulta, los ovinos Blackbelly muestran una tendencia a ser animales productores de carne.
Situation de l"élevage laitier aux asturies (Espagne)
Authors: Barrio de Pedro J. C.
Published: March 2019

L"élevage bovin laitier représente près de la moitié de la marge brute agricole des Asturies, et plus du 10% du quota laitier de l"Espagne. Il s"est produit durant les trente dernières années, un rapide processus d"augmentation de taille des exploitations, d"intensification, de spécialisation et de concentration géographique, très marqué par une plus grande dépendance externe (alimentation, emprunts, amortissements, règlements, aides…) et par une moindre flexibilité face aux risques du marché (prix du lait, coûts des aliments et fournitures) et de la transmission des exploitations. Quelle continuité pour cette activité? Disparition, intensification au sein de sociétés ou solutions alternatives (filières de qualité, pluriactivité…)?

Para evaluar la variabilidad genética de la raza canina Cimarrón Uruguayo, se analizó la totalidad de la información genealógica disponible (n= 6079) utilizando el programa informático ENDOG v4.5. Los datos recabados sugieren sobrerepresen-tación de determinados reproductores y pérdida de genotipos fundacionales. La F media para la población de referencia viva apta para la reproducción fue de 0,03, la cual ha aumentado en generaciones recientes. La población ha tenido una evolución favorable en relación a crecimiento en número de individuos, aunque es muy heterogénea y requiere la aplicación de criterios en los cruzamientos que tiendan a minimizar el nivel de consanguinidad por generación.

Published: March 2019

Se evaluó el efecto de células de granulosa preincubadas sobre la maduración in vitro y producción de hormonas esteroides en vacas. Las células de granulosa de los ovarios fueron cultivadas empleando el M-199 modificado con sales de Earle. Se añadió 1% de albúmina de suero bovino y 5% de suero fetal de ternero. También se incluyó un 0,8% de antibióticos. Los cultivos fueron incubados a 37°C con 95% de aire y 100% de humedad relativa. Se registraron diferencias significativas entre las concentraciones de progesterona y estradiol obtenidas con los niveles de inclsuión de FSH y LH. Puede concluirse que es necesario suplementar con hormonas el medio de cultivo para IVM en bovinos.

Cylinder axis agreement: unexpected scenarios
Authors: Nabil Karim Mahmoud
Published: March 2019

Background

The purpose of this retrospective study was to evaluate cylinder axis agreement between manifest refraction (MR), cycloplegic refraction (CR), Allegro Oculyzer ІІ and Allegro Topolyzer-Vario.

Methods

We included 82 patients (32 males and 50 females, 28.1 ± 8.7 years old), with 156 eyes scheduled for wavefront optimized laser refractive surgery, photorefractive keratectomy (PRK) in 50 eyes and laser- assisted in situ keratomileusis (LASIK) in 106 eyes, for correction of simple, myopic, hyperopic or mixed astigmatism. Cylinder axis was determined under manifest and cycloplegic refractions and using Allegro Occulyzer ІІ and Allegro Topolyzer-Vario platforms. Cylinder axis agreement was assessed by Intra class Correlation coefficient, Pearson Correlation coefficient and by the method described by Bland and Altman.

Results

Intra class Correlation Coefficient and Pearson Correlation Coefficient showed statistically significant cylinder axis agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario (p <0.001*).

Despite statistically significant cylinder axis agreement between the four measuring tools, 4 of 156 eyes (2.5%) showed unexpected discrepancy between Allegro Oculyzer ІІ and Allegro Topolyzer-Vario cylinder axis.

Conclusions

Although cylinder axis shows statistically significant agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario, unexpected discrepancies occur.
Choroidal Structural Changes Correlate with Severity of Diabetic Retinopathy in Diabetes Mellitus
Authors: Wang Hui , Tao Yong
Published: March 2019

Background This study aimes to investigate the choroidal thickness and choroidal vascularity index (CVI) and their correlation with severity of diabetic retinopathy (DR) in diabetes mellitus (DM) patients. Methods An observational cross-sectional study was conducted of 104 eyes, which were divided into 4 groups: Healthy controls (n = 38), DM with no DR eyes (n = 22), non-proliferative DR (NPDR) eyes (n = 24), proliferative DR (PDR) eyes (n = 20). Optical coherence tomography (OCT) was performed. The total choroidal area (TCA), stromal area (SA), the luminal areas (LA) and CVI were compared. Results The CVI values was 67.53 ± 6.20 in controls and 63.43 ± 4.47 in DM eyes (P < 0.001). But there were no statistically significant differences in retinal nerve fiber layer (RNFL), retinal thickness and subfoveal choroidal thickness (SCT) measurements between the two groups (P = 0.407, P = 0.654 and P = 0.849; respectively). The vessel density values were significantly different in DM with no DR eyes, NPDR eyes and PDR eyes. (P < 0.001 for SCT, TCA and SA). The CVIs in the three groups were significant different CVI (P = 0.019). Conclusion Eyes of patients with DM showed decreased CVI compared with normal controls. Choroidal thickness and CVI significantly increased with severity of DR eyes compared with DM eyes and normal. Changes in CVI may predict DR development or recurrence before they are otherwise evident clinically. Choroidal blood flow deficit can be an early pathologic change in DR.
Soil Amendments and Soil Profiling Impact on Macadamia Growth and Yield Performance
Authors: Galanti Russell , Cho Alyssa , Ahmad Amjad , Radovich Theodore
Published: March 2019

Macadamia (Macadamia integrifolia, Maiden & Betche) orchard management in Hawaii can result in the loss of organic matter and soil degradation. The objective of this study was to determine the effects of macadamia husk mulch, husk mulch combined with biochar, husk mulch combined with effective microorganisms (EM), soil profiling, and wood chip mulch on yield, nut quality, root growth, and SPAD values during a 1-year study of mature macadamia orchards at two locations in Hawaii. A partial cost–benefit analysis was performed to compare the costs and yield benefits of each treatment. Soil profiling resulted in higher yields than any other treatment, at a mean of 86.6 kg wet-in-husk per tree. No treatments significantly affected nut quality or dry kernel weight. Nut quality was affected by harvesting time, with the earliest harvesting (Aug. 2017) period resulting in the highest recovery rate of number 1 grade kernels (33%). SPAD values increased with the husk mulch combined with EM (6.5%) treatment and soil profiling treatment (6.9%). Husk combined with EM caused an 87% increase in total root biomass during the study period due to increased proteoid root biomass. The soil profiling treatment had the second lowest estimated cost per hectare and had the highest estimated partial profit per hectare. Soil profiling is a destructive management practice and should be used judiciously until its long-term effects on orchard health are studied. The inoculation of EM or sugar signaling may have been responsible for the proliferation of proteoid roots with the husk mulch and EM treatment.
Are We on the Same Page? Exploring National, State, and Local Educational-response Themes for Extension Master Gardener Coordinators and Volunteers
Authors: Dorn Sheri , Newberry Milton G. , Bauske Ellen M. , Pennisi Svoboda V.
Published: March 2019

Extension provides outreach to the general public and works to disseminate the latest information and research generated by land grant university (LGU) scientists. The Extension Master Gardener (EMG) volunteer program is one of the most widely recognized programs of extension, created to educate people about research-based consumer horticulture (CH) and gardening practices through a network of trained volunteers. Ideally, EMG program initiatives should address local issues and needs and align with the priorities of extension’s federal stakeholder, U.S. Department of Agriculture National Institute for Food and Agriculture (USDA NIFA). Before 2015, there were no national standards for EMG volunteer programs, and at this time, there is no official work plan or prioritization of educational programming. A quantitative national study of EMG state and local coordinators and volunteers was conducted in Fall 2016 to assess the importance of six educational-response themes (ERTs) (i.e., the strategy for EMG volunteer outreach) for program management (state and local coordinators) and program participants (EMG volunteers). The study compared theme importance between program management and participants, and, in turn, allowed a comparison with previously published historical data. Response to individual inquiry is consistently the most important ERT for EMG programs, regardless of the responder position within the program (management or volunteer). Results revealed that state and local coordinators (program management) score ERTs similarly. EMG volunteers score the importance of ERTs similarly to each other, as well, although some differences are apparent between urban, suburban, and rural programs. Although there are slight differences in the importance of response themes between program management and EMG volunteers, it appears that the EMG volunteer program has an effective organizational structure with an upper and middle management generally aligned at every level. It is plausible that the variability in importance of response themes could be attributed to nuances in local issues and needs. Historical comparison indicates that the importance of ERTs has changed over time, suggesting that themes cycle and change. Although the EMG program does not have a national plan for programming, this assessment of EMG volunteer program ERTs provides a perspective on program direction and a useful starting point for discussion. It is a timely conversation, as EMG programs are increasingly expected to be more accountable and show community impact, and these assessments serve as an important baseline for a national program poised for growth and development.
