PURPOSE: In obesity prevention, understanding psychosocial influences in early life is pivotal. Reviews reported contradictory results and a lack of longitudinal studies focusing on underlying lifestyle factors. This study tested whether psychosocial Quality-Of-Life (QOL) was associated with pre-schoolers' lifestyle and adiposity changes over one school year and whether lifestyle moderated the latter. It was hypothesised that QOL might not impact adiposity in everybody but that this might depend on preceding lifestyle. METHOD: Longitudinal data from 291 Swiss pre-schoolers (initially 3.9-6.3 years) was available. The following measures were used in longitudinal regressions: psychosocial QOL by PedsQL, adiposity (BMI z-score, waist, fat%), diet (food frequency), sedentary time and accelerometer-based activity. RESULTS: Concerning lifestyle, low psychosocial QOL was only related to unfavourable changes in diet (less fruit β = 0.21 and more fat intake β = -0.28) and lower physical activity (β = 0.21). Longitudinal QOL-adiposity relations appeared only after moderation by lifestyle factors (beta-range 0.13-0.67). Low psychosocial QOL was associated with increased adiposity in children with an unhealthy diet intake or high sedentary time. By contrast, low psychosocial QOL was associated with decreasing adiposity in high fruit consumers or more physically active pre-schoolers. CONCLUSION: Results emphasise the need for testing moderation in the QOL-adiposity relation. An unhealthy diet can be a vulnerability factor and high physical activity a protective factor in QOL-related adiposity. Consequently, QOL and lifestyle should be targeted concurrently in multi-factorial obesity prevention. The environment should be an 'activity encouraging, healthy food zone' that minimises opportunities for stress-induced eating. In addition, appropriate stress coping skills should be acquired.

The purpose of this qualitative research study was to foster an understanding of the rehabilitation counselling practice offamilies of the brain-injured. Specifically, the study explores the perceptions of stakeholders in regards to the degree of satisfaction with the quality of service received. Questionnaires were administered, and semi-structured, openended interviews were conducted, with six participating families (n=8). Preliminary data were collected via two instruments: (i) the Family Participant Questionnaire, consisting of participants' sample characteristics, information pertaining to the history of the family, details of the injury, and information relating to the type, use, and need offamily services utilized; and (ii) the Community Integration Questionnaire, a measurement of the degree of social displacementllevel of community integration of the injured family member. Utilizing the procedural steps outlined by Colaizzi's (1978) method of protocol analysis, recommendations for a future program based on related and current family needs are discussed in detail. Substantiating and supporting information are offered to rehabilitation practitioners, educational planners, and policymakers alike, concerning the degree of satisfaction with rehabilitative service, and the means of improving upon the overall quality of health care to families of the brain-injured. Implications for clinical practice and research are also raised for discussion.

Health regulatory colleges promote quality practice and continued competence through Quality Assurance (QA) programs. For many colleges, a QA program includes the use of portfolios that incorporate self-directed learning. The purpose of this study was to determine some of the issues surrounding the effectiveness of QA portfolio programs. The literature review revealed that portfolios are valuable tools, but gaps in knowledge include a comparative analysis of QA programs and the perspective of regulatory college administrators. Data were collected through interviews with 6 administrators and a review of 14 portfolio models described on college websites. The results from the two data sources were applied to Robert Stake's responsive evaluation framework to identify issues related to the portfolio's effectiveness (Stake, 1967). The learning components of portfolios were analyzed through the humanist and constructivist lenses. All 14 portfolio models were found to have 3 main components: self-diagnosis, learning plan and activities, and self-evaluation. However, differences were uncovered in learners' autonomy in selecting learning activities, methods of portfolio evaluation, and the relationship between the portfolio and other QA components. The results revealed a dual philosophy of learning in portfolio models and an apparent contradiction between the needs of the individual learner and the organization. Paths for future research include the tenuous relationship between competence and learning, and the impact of technical approaches on selfdirected learning initiatives. A key recommendation is to acknowledge the unique identity of each profession so that health regulatory colleges can address legislative demands and learner needs.

L’augmentation de la population âgée dans la société indique que les systèmes de soins de la santé font face à de nouveaux défis. Les hauts niveaux d’incapacité qui en résultent peuvent être réduits par les nouvelles technologies, la promotion de la santé ainsi que des stratégies de prévention. Les écrits scientifiques récents soulignent la supériorité des prothèses dentaires implanto-portées par rapport aux prothèses conventionnelles en termes de satisfaction et de qualité de la vie des patients. Cependant, il n'est toujours pas clair si ces avantages ont des effets positifs à long terme sur la santé orale et générale ainsi que sur la qualité de vie des populations âgées. Objectifs, Hypothèses : Notre but était de mesurer l’impact des prothèses mandibulaires retenues par 2 implants sur la qualité de vie associée à la santé bucco-dentaire et générale ainsi que sur la santé orale et la qualité du sommeil des aînés édentés. Nous avons évalué les hypothèses nulles suivantes : il n'y a aucune différence entre les individus portants des prothèses mandibulaires retenues par 2 implants (IODs) et ceux qui portent des prothèses conventionnelles (CDs), par rapport à la qualité de vie reliée à la santé bucco-dentaire et générale, la santé orale et la qualité du sommeil, un an après avoir reçu leurs nouvelles prothèses. Méthodes : Dans cette étude randomisée contrôlée, 255 aînés ont reçu au hasard IODs ou les CDs, les deux types de prothèses étant opposés à des prothèses maxillaires conventionnelles. La qualité de la vie reliée à la santé bucco-dentaire (OHRQoL) et la santé générale subjective ont été mesurées avec les questionnaires Oral Health Impact Profile (OHIP-20) et Short Form-36 (SF-36) en condition pré-traitement et après un an. La qualité du sommeil et la somnolence diurne ont été mesurées à l’aide du questionnaire Qualité de Sommeil de Pittsburg et de l'Échelle de Somnolence Epworth. La santé orale a été évaluée par un examen clinique. Les variables indépendantes étaient le sens de cohérence et le type de prosthèse, ainsi que des variables socio-démographiques. En utilisant des analyses statistiques bi et multi-factorielles, des comparaisons à l’intérieur d’un même groupe et entre deux groupes ont été effectuées. Résultats : Les différences pré et post traitement pour les cotes OHIP étaient significativement plus grandes pour le groupe IOD que le groupe CD (p<0.05). Le type de traitement et la cote pré-traitement étaient des facteurs significatifs à OHRQoL (p < 0.0001). Dans le groupe CD, il y avait une diminution significative par rapport aux cotes de «Physical Component Scores (PCS)», le fonctionnement physique, le rôle physique et la douleur physique entre les données pré-traitement et un an après le traitement, ce qui indique une diminution au niveau de la santé générale subjective. Dans le groupe IOD, une diminution statistiquement non significative a été remarquée par rapport à toutes les cotes des sous-échelles de SF-36, sauf pour la douleur physique. Le modèle final de régression a démontré qu’après ajustement pour les variables âge, sexe, statut marital et type de traitement, la cote totale finale d’OHIP et les données de bases de PCS prédisaient la cote finale de PCS (p < 0.0001). Aucune corrélation significative entre sens de cohérence et OHRQoL n'a été détectée (r =-0.1; p > 0.05). Les aînés porteurs des prothèses conventionnelles avaient presque 5 fois plus de chance d’avoir une stomatite prothétique que ceux portant des prothèses mandibulaires hybrides retenues par 2 implants (p < 0.0001). Les aînés ayant subjectivement une mauvaise santé générale avaient une qualité de sommeil moins bonne que ceux avec une meilleure santé générale subjective (p < 0.05). Les personnes qui avaient une OHRQoL moins bonne étaient presque 4 fois plus somnolentes pendant le jour que celles avec une meilleure OHRQoL (p=0.003, χ2; OR =3.8 CI 1.5 to 9.8). L'analyse de régression a montré que la santé générale subjective et OHRQoL prévoient la qualité du sommeil (p=0.022 et p=0.001, respectivement) et la somnolence diurne (p=0.017 et p=0.005, respectivement). Conclusions: Les résultats de cette étude suggèrent que, chez les aînés édentés, des prothèses mandibulaires hybrides retenues par deux implants amènent une amélioration significative de la qualité de vie reliée à la santé bucco-dentaire et maintiennent la sensation d’une meilleure santé physique. Des prothèses hybrides implanto-portées peuvent contribuer à la santé orale en réduisant les traumatismes infligés à la muqueuse orale et en contrôlant la stomatite prothétique. Les aînés édentés dont le niveau de qualité de vie reliée à la santé bucco-dentaire est bas, peuvent aussi avoir des troubles de qualité du sommeil.

The research work which was carried out to study the impact of ISO 9001: 2000, in selected organisations in Kerala, spread over various types of activities, such as fabrication of aero space hardware, glass ware, construction industries, health care units etc, encompassing, government and private enterprises, public sector undertakings, small and medium scale industries and research and development establishments. The ambience, work culture and collaboration prevalent in these organisations were varying on account of the environment in which they have been working. Fifty percent of the organizations selected for the study had obtained the ISO 900 I: 2000-certification since seven years or more. The process of study undertaken could invoke interest in the respondents, when a brief explanation on the purpose and need of the study was given to them prior to conducting the survey. There has been total cooperation from the management and the employees of all the organisations for the conduct of the study. Personal discussions were held with the senior management to draw their total support and involvement for the study.

The Kerala Water Authority requested the School of Environmental Studies to carry out investigations on the mechanism of sporadic mobilization of iron and odour in the raw water drawn to the drinking water treatment plant. The currently used treatment process failed to remove iron completely. This led to problems in the filter and complaints of taste and colour due to iron in the finished water. The sporadic nature of the problem itself made the trouble shooting difficult. The problem was looked in from three points of view. 1. Influence of environmental (climatic) conditions on the dynamics of the relevant basin of the reservoir. 2. Influence of the physical dynamics on the physico — chemical quality of water. 3. Identification of cost-effective treatment processes to suit the existing plant. Since the problem emerged only during the post- monsoon to pre-monsoon months, a related problem was investigated, namely, influence of anions on the oxidation of Fe(II) in natural waters by air. This is presented in Part II of the dissertation.

Everywhere, on the coastal belt it is proved without doubt that the pristine ground water quality was severely deteriorated after the 26 December 2004 Indian Ocean Tsunami. But how far is more relevant, as it is decided by the so-called pre-tsunamic situation of the region. In water quality studies it is this reference finger print which earmarks regional ground water chemistry based on which the monthly variability could rationally be interpreted. This Ph D thesis comprises the testing and evaluation of the facts: whether there is any significant difference in the water quality parameters under study between stations and between months in Tsunami Affected Dug Wells (TADW). Whether the selected water quality parameters vary significantly from BIS and WHO standards. Whether the water quality index (WQI) differ significantly between Tsunami Affected Dug Wells (TADW) and Bore Wells (BW). Whether there is any significant difference in the water quality parameters during December 2005 and December 2008. Is there any significant change in the Water Quality Parameters before 2001 and after tsunami (2005) in TADW.

OBJECTIVES: This contribution provides a unifying concept for meta-analysis integrating the handling of unobserved heterogeneity, study covariates, publication bias and study quality. It is important to consider these issues simultaneously to avoid the occurrence of artifacts, and a method for doing so is suggested here. METHODS: The approach is based upon the meta-likelihood in combination with a general linear nonparametric mixed model, which lays the ground for all inferential conclusions suggested here. RESULTS: The concept is illustrated at hand of a meta-analysis investigating the relationship of hormone replacement therapy and breast cancer. The phenomenon of interest has been investigated in many studies for a considerable time and different results were reported. In 1992 a meta-analysis by Sillero-Arenas et al. concluded a small, but significant overall effect of 1.06 on the relative risk scale. Using the meta-likelihood approach it is demonstrated here that this meta-analysis is due to considerable unobserved heterogeneity. Furthermore, it is shown that new methods are available to model this heterogeneity successfully. It is argued further to include available study covariates to explain this heterogeneity in the meta-analysis at hand. CONCLUSIONS: The topic of HRT and breast cancer has again very recently become an issue of public debate, when results of a large trial investigating the health effects of hormone replacement therapy were published indicating an increased risk for breast cancer (risk ratio of 1.26). Using an adequate regression model in the previously published meta-analysis an adjusted estimate of effect of 1.14 can be given which is considerably higher than the one published in the meta-analysis of Sillero-Arenas et al. In summary, it is hoped that the method suggested here contributes further to a good meta-analytic practice in public health and clinical disciplines.
Effect of internal partitioning on indoor air quality of rooms with mixing ventilation - basic study
Resumo:
The internal partitioning, which is frequently introduced in open-space planning due to its flexibility, was tested to study its effects on the room air quality as well as ventilation performance. For the study, physical tests using a small model room and numerical modeling using CFD computation were utilized to evaluate different test conditions employing mixing ventilation from the ceiling. The partition parameters, such as its location, height, and the gap underneath, as well as contaminant source location were tested under isothermal conditions. This paper summarizes the results from the study.
