TRANSPORT ET CARACTERISATION DES MATIERES EN SUSPENSION DANS LE BASSIN DE LA SEINE : IDENTIFICATION DE SIGNATURES NATURELLES ET ANTHROPIQUES

26 p. (version du 7 janvier 2008, mise en forme)International audienceLa plupart des polluants responsables de la dégradation des cours d'eau sont contrôlés par le comportement des Matières En Suspension (MES). Si leur rôle dans le transport des polluants n'est plus à démontrer, en revanche, l'identification de leurs sources et puits reste problématique. L'objet de ce travail a été de développer une méthodologie permettant de préciser l'origine des MES et de suivre leur transfert sur le bassin de la Seine. Cette méthodologie combine - l'identification d'une large palette d'éléments (analyse par activation neutronique) ne se limitant pas aux seuls polluants, -un échantillonnage par trappes à sédiments sur l'ensemble du bassin et avec un suivi régulier sur la période 1999 2002, - un traitement statistique de l'information recueillie. Cette méthodologie a permis de préciser à quelle échelle les signatures multiélémentaires portées par les MES se différencient les unes des autres, et à quelle logique obéissent les différences observées. Ainsi, signatures naturelles et signatures anthropiques ont pu être distinguées. Les premières témoignent des différences de lithologie existant sur le bassin (Cs/Sc, Ca, Hf, Na, Terres Rares lourdes/Terres Rares légères). Parmi les secondes, certaines marquent des zones de contamination étendue (Zn/7Be, Sb, Cr, Au, Ag) tandis que d'autres identifient une pollution plus localisée (Th/La). Grâce à cette méthodologie, il est donc possible de préciser l'origine des MES et de suivre leur transfert de l'amont vers l'aval. Ces résultats offrent donc la possibilité d'un meilleur contrôle des transferts de sédiments, outil indispensable aux gestionnaires et usagers de l'eau

An empirical research on the effects of“ 100-yen breakfast” as a breakfast promotion project on university students’ studies, lives and health

多面的な学生支援上の目的から、本学において継続実施している100円朝食事業について、その支援効果の把握、および事業アセスメントのための資料集積を目的とし、「100円朝食の利用」に関する実態調査、ならびに「100円朝食の利用」が「修学意識」、「生活習慣」、ならびに「心身の健康」に及ぼす影響についての実証研究をおこなった。 学生を対象とする質問紙調査を2018年12 月に実施し、得られたデータに対し、100円朝食の利用の実態報告としてのデータ整理と、統計分析を用いた支援効果の検証をおこなった。その結果、100円朝食に対する学生の満足度の高さや、学生が100円朝食に対して捉えている意義、また心身の健康の維持への寄与等が示された。departmental bulletin pape

Suboptimal management of severe menopausal symptoms by Nigerian Gynaecologists: a call for mandatory continuing medical education for physicians

<p>Abstract</p> <p>Background</p> <p>Effective management of menopause is an important way to improve the quality of life of the increasing number of older women. The study sought to find out if Nigerian Gynaecologists offer effective treatment for severe menopausal symptoms.</p> <p>Methods</p> <p>126 Nigerian Gynaecologists representing the six health zones of Nigeria were interviewed to determine the menopausal symptoms they had ever encountered in their practices, frequency of the symptoms, treatments ever offered for severe symptoms including their attitude to, and practice of hormone replacement therapy.</p> <p>Results</p> <p>A Nigerian Gynaecologist encountered an average of one patient with menopausal symptoms every three months (range: 0-3 patients per month). The commoner symptoms they encountered were hot flushes (88%), insomnia (75.4%), depression (58.0%), irritability (56.3%), night sweats (55.6%) and muscle pains (54.8%) while urinary symptoms (16.7%) and fracture (1.6%) were less common. Treatments ever offered for severe symptoms were reassurance (90.5%), anxiolytics (68.3%), analgesics (14.3), HRT (7.9%), Vitamins (4%), Beta-blockers (3.2%) and Danazol (2.4%). These treatments were offered as a matter of institutional traditions rather than being based on any evidence of their efficacy.</p> <p>Conclusion</p> <p>The result revealed that most Nigerian Gynaecologists prefer reassurance and anxiolytics for managing severe menopausal symptoms instead of evidence-based effective therapies. A policy of mandatory continuing medical education for Nigerian physicians is recommended to ensure evidence-based management of gynaecological problems, including menopause.</p

Identification of Emotion from Body Movements: A Cross-Cultural Study of Americans and Japanese

In the present study American and Japanese subjects' judgments of emotional cues in body movements were compared, when facial information was excluded. Seven fundamental emotions of joy, surprise, fear, sadness, disgust, anger, contempt and three affective-cognitive structures for the emotions of affection, anticipation, and acceptance were displayed by four Japanese actors/actresses with their backs turned toward the viewer. The emotions of sadness, fear, and anger as expressed in kinetic movement showed high agreement between the two cultural groups. Joy and surprise, even though they are classified as fundamental emotions, contained some cultural components that affected the judgments. Furthermore, USA subjects successfully identified disgust as portrayed by Japanese actors/actresses, but Japanese subjects did not identify the expressions of disgust or contempt. Affection, anticipation, and acceptance have some cultural components that are interpreted differently by Japanese and Americans, and this accounted for some of the misunderstandings. Nevertheless, most of the scenes depicting emotions and affective-cognitive structures emotions were correctly identified by the subjects of each culture. </jats:p
