Urinary iodine levels in children (5–11 years) and in adult males and females (15–44 years) of three ecological zones (hilly, flood-prone and plains) of Bangladesh were analyzed to determine the status of biochemical iodine deficiency in the country. Data indicated that a large majority of the population all over Bangladesh have biochemical iodine deficiency urinary iodine excretion (UIE) less than the accepted cut-off level of 10 μg/dl. Adults were deficient to comparable degrees, 31.3% severely iodine deficient. The flood-prone zone was less affected: 71.7% children had iodine deficiency and 25% were severely deficient. Adults of this zone were less affected than the children. Iodine deficiency was least severe in the plain zone: 59.8% children were biochemically iodine deficient and of them 23.4% had UIE less than 2.0 μg/dl. In the case of the adults of this zone, 60.8% were biochemically iodine deficient and 20.6% had severe iodine deficiency. The results indicate that Bangladesh as a whole is an iodine deficient region, with the hilly zone being the most severely affected. Children were slightly more affected than the adults, and females were more affected than the males.  相似文献

Abstract

An NHS Trust set up groups to teach social skills to children and adolescents using a cognitive behavioural framework. One group of seven children (five boys and two girls) is described. Parents were invited to a parallel parents' group. Each group lasted for 90 minutes and ran weekly for 6 weeks. Extensive liaison with parents and teachers took place before, during and after the group. Analysis of pre- and postgroup questionnaires sent to parents and teachers indicated improved social functioning, outside the group, for most of the children. Parents valued the dialogue with professionals and often felt supported by them for the first time. Therapists' contact with teachers ensured full knowledge of children's behaviour and the transfer of skills to schools. Cognitive behavioural techniques with children under-going group work require intensive liaison to facilitate generalization of skills learnt.  相似文献

Most people in Bangladesh are rural, poor and underprivileged. The incidence of sexual disease has increased, but little has been done to educate rural people about sexual and reproductive health. In 1997, a sexual and reproductive health project was initiated within a collaborative research agreement between the International Centre for Diarrhoeal Disease Research (ICDDR,B) and the Bangladesh Rural Advancement Committee (BRAC), an indigenous non-governmental organization which pursues integrated rural development strategies. Qualitative in-depth interviews with 65 different women, men, boys and girls revealed significant sexual health problems and a lack of knowledge of sexual and reproductive health. The interviews were transformed into composite problem-solving picture stories and information about sexual and reproductive health. Stories mirrored respondents' interpretations of sexual behavior. Those who had achieved or ascribed legitimacy to talk about sex, e.g. traditional health providers, were trained to utilize the methods and materials. Qualitative evaluations revealed important changes in health providers' self-confidence, business and personal interactions as well as changes in clients' behavior. This project found that sexual and reproductive health education can be integrated into indigenous health activities if the sociocultural context in which sex, relationships, risks, diseases and communication occur is reflected in a program's content and methods. Unquestionably, there is a great need for sex education in rural Bangladesh.  相似文献

Abstract

The method of normalisation combined with peer ratings is utilised to provide the solution to the biased rating problem of mapping group work marks to individual marks. We critically evaluate the method of normalisation following the findings of an article which argued against the use of self and/or peer rating mechanism. We demonstrate that the findings of that article also hold for the method of normalisation as the influence of human behavioural factors are not accommodated in the designs. Additionally, we argue that the method (and its variants) is rather complicated, where all possible contingencies are not pre-specified. It makes the arrangement between tutors and students in conducting peer assessments incomplete and unverifiable by a third party.  相似文献

Objective

Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation.

Methods

In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation.

Results

The study demonstrated that low doses (10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam (10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples.

Conclusions

Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics.  相似文献

Social media content generated by learning communities within universities is serving both pedagogical and marketing purposes. There is currently a dearth of literature related to social media use at the departmental level within Higher Education Institutions (HEIs). This study explores the multi-voiced interactions of a UK Psychology department’s ‘rotation curation’ approach to using Twitter. An in-depth analysis of a corpus of 4342 tweets by 58 curators (14 staff, 41 students, and 3 guest curators) was carried out using a combination of computer-assisted and manual techniques to generate a quantitative content analysis. The interactions received (e.g. retweets and favorites) and type of content posted (e.g. original tweets, retweets and replies) varied by curator type. Student curators were more likely to gain interactions from other students in comparison to staff. This paper discusses the benefits and potential limitations of a multi-voiced ‘rotation curation’ approach to social media management.  相似文献

Two sulfonylurea herbicides, metsulfuron methyl (Ally 20 WP) and chlorimuron ethyl (Classic 25 WP) were evaluated for their dissipation bchaviour in alluvial, coastal saline and laterite soils under laboratory incubated condition at 60% water holding capacity of soils and 30 ℃ temperature was maintained. In field study herbicides were applied twice for the control of grasses, annual and perennials broad leaves weeds and sedges in rice, wheat and soybean to find out the residual fate of both the herbicides on different matrices of respective crops after harvest. Extraction and clean up methodologies for the herbicides were standardized and subsequently analyzed by HPLC. The study revealed that the half-lives of metsulfuron methyl and chlorimuron ethyl ranged from 10.75 to 13.94 d irrespective of soils and doses applied. Field trials with rice, wheat and soybean also revealed that these two herbicides could safely be recommended for application as no residues were detected in the harvest samples.  相似文献
