Two softwares were compared: Dolphin Imaging and Dentofacial Planner Plus. Pictures were taken from twelve patients with mandibular hypoplasia in the preoperative and at least 5 months postoperative period.

Este estudo teve como objetivo avaliar as alterações dentoesqueléticas e tegumentares do aparelho Twin-block por meio de 42 terradiografias em norma lateral que foram obtidas em duas épocas, T1 antes do tratamento e T2 ao final do tratamento ortopédico de 21 jovens brasileiros, de ambos os gêneros, com idade média de 10,5 anos (mínimo: 9,25 anos; máximo: 12,5 anos) portadores de má oclusão de Classe II com retrognatismo mandibular tratados com este aparelho na Disciplina de Ortodontia da Faculdade de Odontologia de Bauru, Universidade de São Paulo (FOB-USP) e comparados a três amostras com as mesmas características tratadas com os aparelhos ortopédicos Bionator (22 jovens, com idade média de 10,42 anos, mínimo: 8,08 anos; máximo: 12,58 anos) e Herbst (22 jovens, com idade média de 10,48 anos, mínimo: 8,00 anos; máximo:12,75 anos) a um grupo controle de Classe II (24 jovens, com idade média de 9,97 anos, mínimo: 8,33 anos; máximo: 11,67 anos), sem tratamento; num total de 178 telerradiografias em norma lateral. Todos os pacientes se encontravam no mesmo estágio de maturação das vértebras cervicais (início: CVMSII; final: CVMSIII). ANOVA, teste de Tukey e teste t pareado foram aplicados. Os resultados mostraram que todos os aparelhos melhoraram a relação maxilomandibular, as relações dentárias, diminuindo a severidade da má oclusão de Classe II, porém com maiores efeitos esqueléticos nos grupos Twin-block e Bionator, com maior protrusão mandibular e crescimento mandibular, corpo e ramo, respectivamente, e mais efeitos dentoalvelares no grupo Herbst com significante vestibularização e protrusão dos incisivos inferiores. / This study had as aim to assess the dentoskeletal and soft tissue effects of the Twin-block appliance by means of 42 lateral cephalometric radiographs obtained in T1, before treatment, and T2, at the end of the orthopedic treatment, of 21 Brazilian subjects of both genders, mean age of 10.5 years, minimum: 9.25 years; maximum: 12.5 years with Class II malocclusion associated to a mandibular retrognathism treated in the Orthodontic Discipline at Bauru Dental School, University of Sao Paulo and compared to three samples with the same features with the functional appliances, Bionator (22 subjects, 10.42 years, minimum: 8.08 years; maximum:12.58 years), Herbst (22 subjects, 10.48 years; minimum: 8.00; maximum:12.75 years) and an untreated Class II control group (24 subjects, 9.97 years, minimum: 8.33 years; maximum: 11.67 years) in a total of 178 lateral cephalometric radiographs. All patients were in the same cervical vertebral maturation stages (initial: CVMSII; final: CVMSIII). Analysis of Variance (ANOVA) , Tukey test and pared t test were applied. The results showed that all appliances corrected the maxillomandibular relationship, dental relationships reducing the Class II malocclusion severity with more skeletal effects, significant mandibular protrusion, mandibular growth, body and ramus, with Twin-block and Bionator, respectively, and more dentoalveolar effects with Herbst appliance, with significant protrusion and vestibular inclination of the lower incisors.

This dissertation describes a study undertaken in Limpopo Province and is based on the GPAP project which was created under the auspices of LIMPAST through an established working partnership of ARC-GCI and LDA extension services. The study aimed at analysing the impact of the Grain Production Advancement Project on farmers’ production efficiency; and to determine factors that could have possibly affected the implementation of improved maize cultivars and essential maize production practices at farmer level. In essence, two important phenomena of the study are addressed: train-the-trainer, and also train the farmer. Through the GPAP project, farmer groups were formed and capacitated. Extension officers seconded to the project were also capacitated to implement the project through On-farm trials, Demonstrations and Farmer Field Schools. A combination of explorative and conceptual analytical techniques was used for data analysis. Explorative analysis was meant to present frequency analysis, and descriptive statistics. In conceptualization analysis, content analysis was used to confirm the descriptions of behaviour and content of documents. Three checklists were administered to respondents. The first checklist was used to ensure efficient group functioning of farmer groups, the second checklist was used to determine mobilisation of farmer groups and the third checklist determined the extent to which leader farmers implemented the training program for Aganang leader farmer group. A questionnaire was also used to determine extension officers’ perceptions on the following aspects: <ul> <li> Farmer participation;</li> <li> Implementation tools;</li> <li> Production efficiency; and</li> <li> Factors that led to poor implementation.</li> </ul> A Screening Instrument was used to predict the chances of the selected individual leader farmers from the Aganang district, to be successful in farming. Findings from the study indicate that 12 on-farm trials were successfully implemented and managed by extension staff and Farmer Field days were well attended in the first two seasons on the project. Farmer groups were formed and respondents revealed that the utmost reason for the formation of a group was to improve their maize production and to increase knowledge and skills. Only 33% of the groups have reached the task/performance stage of group effectiveness. The farmer groups performed on an average level due to the following reasons; there is still a dependency syndrome in farmer groups and a need to improve ownership acceptance by farmers. Extension respondents perceive that for a farmer group to perform efficiently the following needs to be in place: cohesiveness and teamwork, common goal, commitment, interest, self-reliance, participation and ownership. A total of 63% of small-scale farmers have only access to less than one (1) ha of arable land. Adoption of maize cultivars was to a moderate extent and 40% of farmers implemented the recommended farming practices to a great extent. The utmost farmer constraints that were attributed to farmers’ low implementation of farming practices included; drought, land shortage, financial support and labour shortage. However, there was a positive increase in the use of hybrid seed which also improved farmer’s maize productivity levels. In the Aganang municipality, a total of 20 leader farmers were selected for a leadership development program. Nineteen leader farmers completed a Screening Instrument to determine their chances to be successful in farming. The Screening Instrument revealed that only one (1) respondent had a 50% chance to be successful, and three respondents revealed a 26-49% chance to be successful. The Aganang leadership development program provided skills and knowledge to farmers and it was revealed that the leader farmers implemented the skills only to a moderate extent. Overall, the GPAP project had a positive impact on farmer’s productivity efficiency but there is need for a re-look at the project with special attention to the following: <ul> <li> Identification of high potential dry land production areas;</li> <li> The majority of farmer groups are too large and should be divided into smaller groups with clear, specific and measurable objectives; and</li> <li>Serious attention should be given to selected farmers with the best chance of success to participate in the project.</li></ul> Copyright / Dissertation (MSc(Agric))--University of Pretoria, 2010. / Agricultural Economics, Extension and Rural Development / unrestricted

This was a causal-comparative study the Advancement Via Individual Determination (AVID) Program on middle school student academic achievement and attendance. There were two major research questions, which were presented. They were as follows: Is there a statistically significant interaction among gender (males, females), race/ethnicity (blacks, whites), and group membership (Talented and Gifted, AVID) with respect to Stanford 9-TA Partial Battery Normal Curve Equivalent (NCE) achievement total scores after controlling for initial differences in socioeconomic status and, Is there a statistically significant interaction among gender (males, females), race/ethnicity (blacks, whites), and group membership (Talented and Gifted, AVID) with respect to attendance after controlling for initial differences in socioeconomic status? These questions were analyzed using two three way ANCOVAS with 2 x 2 x 2 factorial designs, with a .05 alpha level employed to test for statistical significance. The researcher analyzed standardized testing and attendance data collected on the 1996-1997 eighth-grade student cohort within one mid-sized socioeconomic diverse urban school district. Data were collected on 398 students beginning with the 1994-1995 school year and concluding with the 1996-1997 school year. Data for eighth grade students not enrolled in the Gifted and Talented, or AVID programs for that length of time, neither were used. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS, 1995). Threats to the internal and external validity of this study may be that students have relocated or were not present during test administrations and their Stanford 9-TA Partial Battery Achievement Test data were not available. Test data for students neither blacks or whites, or in AVID or the Talented and Gifted programs for the indicated three-year span were not analyzed. Students missing attendance data were also not included. The creators of AVID, profess that students participating in the AVID program will attend school and achieve academically as well as other groups of children. The researcher's analyses of the data does not substantiate this claim. The data yielded that AVID students produced lower achievement scores on the Partial Battery of the Stanford 9-TA Achievement Test in all areas. It was also found that gender, race/ethnicity and group membership were significant factors. / Ed. D.
