    Odabrana tema istražuje ulogu projektnog menadžmenta u organizaciji recentnih poslovnih događanja na području Republike Hrvatske. U današnje vrijeme svaki poslovni pothvat dobiva naziv projekt, a svaki projekt zahtjeva njegovu kvalitetnu pripremu, realizaciju i postprojektne aktivnosti. Projektni menadžment tada ima veliku ulogu u sastavljanju pravilne organizacijske strukture timova, grupa i/ili poduzeća koja će provesti ideju projekta u djelo. Također, sve ubrzaniji ritam promjena na poslovnim tržištima zahtjeva višu razinu kontinuirane stručne edukacije i informiranosti samih sudionika tržišta o najnovijim kretanjima u djelatnostima u kojima posluju. Tada dolazi do zamjetnog trenda povećanja organiziranja poslovnih konferencija i festivala koje skupno nazivamo poslovna događanja. U sklopu ovog rada provedeno je istraživanje kojim se pokušalo utvrditi kolika je i u kojem obujmu uloga projektnog menadžmenta u organizaciji poslovnih događanja u Hrvatskoj. Ovim istraživanjem zaključeno je da su odstupanja teorije od prakse minimalna. Na uzorku od 26 projektnih menadžera i voditelja projekata dobiveni su rezultati koji ukazuju da su glavne uloge projektnih menadžera kontrola troškova projekta te upravljanje rizicima. Također je bitno zaključiti da su mišljenja svih ispitanika slična te da su odskakanja od prosjeka minimalna, pa čak i zanemariva.The selected topic explores the role of project management in organizing recent business events in the Republic of Croatia. Nowadays, every business venture is called a project, and every project requires its quality preparation, realization and post-project activities. Project management then plays a major role in putting together the proper organizational structure of the teams, groups and / or companies that will put the project idea into action. Also, the accelerating pace of changes in business markets requires a higher level of continuing professional education and awareness of market participants themselves about the latest developments in the industries in which they operate. Then there is a noticeable trend of increasing the organization of business conferences and festivals, collectively referred to as business events. As part of this paper, a study was conducted to determine the extent of the role of project management in organizing business events in Croatia. This research concluded that the deviations of theory from practice are minimal. A sample of 26 project managers obtained results indicating that the main roles of project managers are project cost control and risk management. It is also important to conclude that the opinions of all respondents are similar and that the rebounds from the average are minimal and even negligible

    Brassica oleracea L. var. acephala is an ornamental cabbage cultivated as foliage for cutting due to the coloration of the rosette formed by its apical leaves. The plant height and the diameter of the rosettes may be modified through the planting density; however, there is not enough information about this. The aim of this study was to assess the influence of the planting density of four cultivars of B. oleracea L. var. acephala of the series F1 Crane: Bicolor, Pink, Red and Rose, on the plant height, rosette diameter, number of leaves, leaf area, root volume, and aerial and root fresh and dry weight. The experimental design was completely randomized, with six repetitions. The combination of density (56 plants.m-2 and 28 plants.m-2) and cultivar allowed obtaining eight treatments. The results showed that the treatments with high planting density improved commercial quality indices: achieving greater stem height and more compact and smaller diameter rosettes, leading to lower values of the rest of the vegetative variables evaluated. Also, as productive alternative, it would allow a more efficient use of the soil and reduce crop management activities such as manual leaves removal.Brassica oleracea L. var. acephala se cultiva como follaje para corte debido a la coloración de la roseta de hojas apicales de este repollo ornamental. Es posible modificar la altura de las plantas y el diámetro de las rosetas, para mejorar la calidad comercial, a través de la densidad de plantación, sin embargo, no hay suficiente información al respecto. Se evaluó la influencia de la densidad de plantación en cuatro cultivares de la serie F1 Crane: Bicolor, Pink, Red y Rose, sobre altura del tallo, diámetro de roseta, número de hojas, área foliar, volumen radical y peso fresco y seco, particionados en vástago y raíz. El diseño experimental fue completamente aleatorizado (DCA), con seis repeticiones. Por combinación de factores densidad (56 pl.m-2 y 28 pl.m-2) y cultivar se obtuvieron 8 tratamientos. Una alta densidad de plantación aumentó la calidad comercial de las plantas, las que tuvieron rosetas apicales más compactas y de menor diámetro y mayor altura del tallo, reduciendo el resto de las variables vegetativas. Asimismo, permitiría un uso más eficiente de la tierra disminuyendo tareas de manejo del cultivo tales como el deshoje de las varas.Fil: Kim, Yoo Ree . Universidad de Buenos Aires.

    AbstractThis study examined neighborhood safety as perceived by children (mean age=10 years) and their mothers, and its association with children's physical activity. For all eight safety items examined, children perceived their environment as less dangerous than mothers (p<0.05). None of the multiple regression models predicting children's physical activity by safety perceptions were significant (p>0.10). The maternal perception model explained the highest percentage of variance (R2=0.26), compared to the children's perception model (R2=0.22). Findings suggest that future studies should explore relations between self-reported and objectively measured safety barriers to Hispanic youth walking and cycling

    This study examined neighborhood safety as perceived by children (mean age=10 years) and their mothers, and its association with children\u27s physical activity. For all eight safety items examined, children perceived their environment as less dangerous than mothers (p\u3c0.05). None of the multiple regression models predicting children\u27s physical activity by safety perceptions were significant (p\u3e0.10). The maternal perception model explained the highest percentage of variance (R2=0.26), compared to the children\u27s perception model (R2=0.22).

    The molecular mechanisms that mediate the ischemia-reperfusion (I/R) injury in kidney are not completely understood. It is also largely unknown whether such mechanisms overlap with those governing the early development of kidney.We performed gene expression analysis to investigate the transcriptome changes during regeneration after I/R injury in the rat (0 hr, 6 hr, 24 hr, and 120 hr after reperfusion) and early development of mouse kidney (embryonic day 16 p.c. and postnatal 1 and 7 day). Pathway analysis revealed a wide spectrum of molecular functions that may participate in the regeneration and developmental processes of kidney as well as the functional association between them. While the genes associated with cell cycle, immunity, inflammation, and apoptosis were globally activated during the regeneration after I/R injury, the genes encoding various transporters and metabolic enzymes were down-regulated. We also observed that these injury-associated molecular functions largely overlap with those of early kidney development. In particular, the up-regulation of kinases and kinesins with roles in cell division was common during regeneration and early developmental kidney as validated by real-time PCR and immunohistochemistry.In addition to the candidate genes whose up-regulation constitutes an overlapping expression signature between kidney regeneration and development, this study lays a foundation for studying the functional relationship between two biological processes

    BackgroundExposure to organophosphate (OP) pesticides, well-known neurotoxicants, has been associated with neurobehavioral deficits in children.ObjectivesWe investigated whether OP exposure, as measured by urinary dialkyl phosphate (DAP) metabolites in pregnant women and their children, was associated with attention-related outcomes among Mexican-American children living in an agricultural region of California.MethodsChildren were assessed at ages 3.5 years (n = 331) and 5 years (n = 323). Mothers completed the Child Behavior Checklist (CBCL). We administered the NEPSY-II visual attention subtest to children at 3.5 years and Conners' Kiddie Continuous Performance Test (K-CPT) at 5 years. The K-CPT yielded a standardized attention deficit/hyperactivity disorder (ADHD) Confidence Index score. Psychometricians scored behavior of the 5-year-olds during testing using the Hillside Behavior Rating Scale.ResultsPrenatal DAPs (nanomoles per liter) were nonsignificantly associated with maternal report of attention problems and ADHD at age 3.5 years but were significantly related at age 5 years [CBCL attention problems: β = 0.7 points; 95% confidence interval (CI), 0.2-1.2; ADHD: β = 1.3; 95% CI, 0.4-2.1]. Prenatal DAPs were associated with scores on the K-CPT ADHD Confidence Index &gt; 70th percentile [odds ratio (OR) = 5.1; 95% CI, 1.7-15.7] and with a composite ADHD indicator of the various measures (OR = 3.5; 95% CI, 1.1-10.7). Some outcomes exhibited evidence of effect modification by sex, with associations found only among boys. There was also limited evidence of associations between child DAPs and attention.ConclusionsIn utero DAPs and, to a lesser extent, postnatal DAPs were associated adversely with attention as assessed by maternal report, psychometrician observation, and direct assessment. These associations were somewhat stronger at 5 years than at 3.5 years and were stronger in boys

    <p>Abstract</p> <p>Background</p> <p>Sentinel surveillance for severe acute respiratory infections in hospitals and influenza-like illness in ambulatory clinics is recommended to assist in global pandemic influenza preparedness. Healthcare utilization patterns will affect the generalizability of data from sentinel sites and the potential to use them to estimate burden of disease. The objective of this study was to measure healthcare utilization patterns in Guatemala to inform the establishment of a sentinel surveillance system for influenza and other respiratory infections, and allow estimation of disease burden.</p> <p>Methods</p> <p>We used a stratified, two-stage cluster survey sample to select 1200 households from the Department of Santa Rosa. Trained interviewers screened household residents for self-reported pneumonia in the last year and influenza-like illness (ILI) in the last month and asked about healthcare utilization for each illness episode.</p> <p>Results</p> <p>We surveyed 1131 (94%) households and 5449 residents between October and December 2006 and identified 323 (6%) cases of pneumonia and 628 (13%) cases of ILI. Treatment for pneumonia outside the home was sought by 92% of the children <5 years old and 73% of the persons aged five years and older. For both children <5 years old (53%) and persons aged five years and older (31%) who reported pneumonia, private clinics were the most frequently reported source of care. For ILI, treatment was sought outside the home by 81% of children <5 years old and 65% of persons aged five years and older. Government ambulatory clinics were the most frequently sought source of care for ILI both for children <5 years old (41%) and persons aged five years and older (36%).</p> <p>Conclusions</p> <p>Sentinel surveillance for influenza and other respiratory infections based in government health facilities in Guatemala will significantly underestimate the burden of disease. Adjustment for healthcare utilization practices will permit more accurate estimation of the incidence of influenza and other respiratory pathogens in the community.</p

    BACKGROUND: Organophosphate (OP) pesticides are widely used in agriculture and homes. Animal studies suggest that even moderate doses are neurodevelopmental toxicants, but there are few studies in humans. OBJECTIVES: We investigated the relationship of prenatal and child OP urinary metabolite levels with children’s neurodevelopment. METHODS: Participating children were from a longitudinal birth cohort of primarily Latino farm-worker families in California. We measured six nonspecific dialkylphosphate (DAP) metabolites in maternal and child urine as well as metabolites specific to malathion (MDA) and chlorpyrifos (TCPy) in maternal urine. We examined their association with children’s performance at 6 (n = 396), 12 (n = 395), and 24 (n = 372) months of age on the Bayley Scales of Infant Development [Mental Development (MDI) and Psychomotor Development (PDI) Indices] and mother’s report on the Child Behavior Checklist (CBCL) (n = 356). RESULTS: Generally, pregnancy DAP levels were negatively associated with MDI, but child measures were positively associated. At 24 months of age, these associations reached statistical significance [per 10-fold increase in prenatal DAPs: β = −3.5 points; 95% confidence interval (CI), −6.6 to −0.5; child DAPs: β = 2.4 points; 95% CI, 0.5 to 4.2]. Neither prenatal nor child DAPs were associated with PDI or CBCL attention problems, but both prenatal and postnatal DAPs were associated with risk of pervasive developmental disorder [per 10-fold increase in prenatal DAPs: odds ratio (OR) = 2.3, p = 0.05; child DAPs OR = 1.7, p = 0.04]. MDA and TCPy were not associated with any outcome. CONCLUSIONS: We report adverse associations of prenatal DAPs with mental development and pervasive developmental problems at 24 months of age. Results should be interpreted with caution given the observed positive relationship with postnatal DAPs
