This retrospective case-control study was designed to investigate the relationship between placental localization and intrauterine growth restriction (IUGR). Pregnant women with an anatomic survey from January 1, 2000, to December 31, 2005, and delivery of the pregnancy at Yale-New Haven Hospital (YNHH) were identified using clinical and billing records. Multiple gestation, fetal anomaly, and incomplete medical information were reasons for exclusion. Cases (N=69) were consecutive pregnancies with evidence of IUGR (estimated fetal weight <10th percentile for gestational age) at last follow-up ultrasound. Randomly selected controls (N=258) from the same time period had no evidence of IUGR. Maternal, ultrasound, delivery, and perinatal data were collected by retrospective medical record review, and IUGR cases and non-IUGR controls were compared using the Students t-test, Wilcoxon test, Chi-square analysis, Fishers exact test, and ANOVA. Placental location was determined from the anatomic survey record (obtained at 18.4 ± 1.2 weeks gestation in the IUGR group and 18.2 ± 1.0 weeks gestation in the control group; P=0.18). Multivariate logistic regression with adjustment for confounders was used to investigate the association between IUGR and placental localization. Consistent with known predictors of IUGR, the IUGR group had a higher proportion of black women (36.4% vs. 19.8%, P=0.03), chronic hypertension (26.0% vs. 3.5%, P<0.001), and hypertensive disorders of pregnancy (36.2% vs. 5.0%, P<0.001). Mean birth weights of IUGR and non-IUGR pregnancies differed by 2 kilograms (3244 ± 625 grams vs. 1277 ± 637 grams, P<0.001). IUGR infants were more likely to receive antenatal steroids, deliver preterm, deliver by cesarean section, and be admitted to neonatal intensive care. In both IUGR and non-IUGR pregnancies, the placenta was most commonly anterior or posterior. Unilateral placentas were three times more common in the IUGR group than in the non-IUGR group (17.4% vs. 5.0%, P=0.01). IUGR pregnancies were over four times as likely as control subjects to have unilaterally-located placentas compared to anterior placentas (OR 4.8, 95% confidence interval, 1.9-11.7). Adjusting for ethnicity, chronic hypertension, and hypertensive disorders of pregnancy did not affect this finding (OR 4.6, 95% confidence interval 1.6-13.5). In conclusion, we compared a group of 69 IUGR pregnancies to 258 non-IUGR controls and found intrauterine growth restriction to be associated with unilateral placentation.

Previous research has demonstrated that behavioral skills training (BST) is effective in teaching social skills to individuals with developmental disabilities, but often the skills fail to generalize. One strategy to promote generalization has been the use of in situ training. In an effort to improve upon previous research BST plus in situ training was evaluated to teach greeting skills to adults living in a group home setting. The percentage of correct greeting responses was evaluated in a multiple baseline across participants design. Results showed that BST was only partially effective in teaching greeting skills to the participants. However, In-situ training resulted in a greater increase in correct greeting skills across all participants.

Syftet med fördjupningsarbetet har varit att via en pilotstudie öka kunskapen om ungdomar med funktionsnedsättning i Umeå, med avseende på psykisk hälsa, och på hur de upplever sin vardag i skolan, med kamrater och i familjen. Psykisk hälsa undersöktes genom att ungdomar med funktionsnedsättning som går i specialklasser (grundsärskolans högstadium, högstadium för ungdomar med Asperger, högstadium för ungdomar med rörelsenedsättningar), fick besvara en enkät under skoltid. För att kunna relatera till den undersökning som Statens Folkhälsoinstitut genomförde hos ungdomar i Sverige 2009 har samma enkät använts.   Resultatet visar att de flesta ungdomar har angett att de mår bra, trivs i skolan, har bra kontakt med sina lärare och med sina föräldrar. Majoriteten mår lika bra som de flesta ungdomar i landet och t.om bättre än de ungdomar i Folkhälsoinstitutets undersökning, som angett att de hade någon funktionsnedsättning.   Inom några områden visades dock lägre resultat. Ungdomarna i vår undersökning uppgav att deras svårigheter påverkade deras vardag i familjen och vid fritidsaktiviteter. De umgås mer sällan med kamrater, motionerar mindre och har färre fritidsaktiviteter. Ungdomar med Asperger skiljer ut sig mest i vår undersökning, de är mindre nöjda med livet och med sig själva, känner sig mer ensamma,  umgås mer sällan med kamrater och har mindre kul, jämfört med ungdomar i grundsärskolan.   Det finns områden där stödet ifrån Barn- och ungdomshabiliteringen kan förbättras, som att utveckla metoder för socialt samspel och stärka ungdomarnas identitet och i samarbete med andra aktörer öka delaktigheten till en mer aktiv fritid.

Aim and tasks of the work. The aim of this work is to investigate insufficiently analyzed variants of the electrodynamic super-wide-band slow-wave structures, create their models, improve methods of analysis, analyze properties of the systems and reveal potentiality of the traveling-wave cathode-ray tubes, slow-wave structures. In order to achieve the aim it is necessary: 1. To improve method for evaluation of non-linear distortions in the traveling-wave cathode-ray tubes and reveal possibilities of reduction of non-linear distortions. 2. To create models of the insufficiently analyzed variants of slow-wave structures and reveal properties of the slow-wave structures. 3. To reveal influence of periodical non-homogeneities on properties of slow-wave structures, simulate and reveal influence of transitions to properties of slow-wave structures and traveling-wav cathode-ray tubes. 4. To make investigation of potentiality of slow-wave structures and traveling-wave cathode-ray tubes and select variants of slow-wave structures that can guarantee wide band and high operating speed of the traveling-wave cathode-ray tubes. Scientific novelty and practical value. Models of insufficiently simulated slow-wave structures were created and their properties were analyzed. According to analysis and modeling results, variants of systems were selected that can guarantee the wide pass-band and high operating speed of the traveling-wave cathode-ray tubes.
