AbstractBackground: Infertility in developing countries is higher at 30% compared to developed countries at 5-8%. The factors that influence infertility are maternal (women) age and sperm factors. Therapy in handling infertility in the form of Assisted Reproductive Technology (ART) with one of them is Intrauterine Insemination (IUI). The success rate of IUI is the percentage of IUI programs that give results as desired depending on the type of calculation used such as pregnancy rate or live birth rate. Method: This research is a literature review. The research question with PICO standard is "What is relationship between woman's age and sperm quality with the success of Intrauterine Insemination?". 70 literatures were obtained from Cochrane, Sciencedirect, PubMed, and google scholar databases. Literature screening was done by looking at the inclusion and exclusion criteria that have been set, so that 7 literature will be reviewed.  Results: From all the literature on the relationship of woman's age with the pregnancy rate in the IUI process stated that there was a significant relationship between the age of the woman with the success of IUI. Most of literature (75%) on the relationship of sperm quality with pregnancy rates in the IUI process states that there is a relationship between sperm quality and the success of IUI. The percentage of pregnancies in the IUI program can reach more than 10% with a sperm concentration >10x106/ml. Conclusion: From a review of 7 literature, the age of women who are ideal for IUI is 20-35 years with a pregnancy of  20%. In a sperm concentration >10x106/ml and sperm morphology ≥ 5% can get >10% pregnancy rate, and a pregnancy rate of >8% on sperm motility ≥ 75%.

RESUMOA incidência do câncer de pele vem aumentando a cada ano. Sabe-se que entre outros fatores, a radiação solar é a principal responsável pelo desenvolvimento dessa patologia. A prevenção, feita através da fotoproteção, teria grande impacto nesse cenário. No entanto, as orientações sobre como se proteger dos malefícios do sol devem ser coerentes com a incidência solar da região, os hábitos da população e o fototipo da pele. Os conceitos sobre fotoproteção foram definidos por entidades européias e norte americanas e não devem ser reproduzidos para o Brasil de forma aleatória, pois a incidência solar no Brasil é muito maior, a população tem fototipos diferentes e o hábito de se expor ao sol é muito mais frequente. Portanto, faz-se necessário elaborar conceitos próprios para o Brasil e conscientizar a população sobre os perigos da radiação solar para que a incidência do câncer de pele reduza definitivamente. Essa revisão visa mostrar a relação da radiação solar no Brasil com a pele dos brasileiros e evidenciar a importância da fotoproteção para essa população. Para isso foi feito um levantamento de artigos originais, revisões de literatura, consensos brasileiros e internacionais e livros de dermatologia.Palavras-chave: Fotoproteção, Câncer de pele, Exposição solar, Radiação ultravioleta, Vitamina D. ABSTRACTThe incidence of skin cancer is increasing every year. It is known that among other factors, solar radiation is the main responsible for the development of this pathology. Prevention, made by photoprotection, would have great impact in this scenario. However, the guidelines on how to protect themselves from the sun's harmful effects should be consistent with the sunlight of the region, the habits of the population and the phototype skin. The concepts of photoprotection were defined by European and North American entities and should not be played for Brazil at random, as the solar incidence in Brazil is much higher, people have different skin types and the habit of sun exposure is much more frequent. Therefore, it is necessary to draw up own concepts for Brazil and raise awareness about the dangers of solar radiation, so that the incidence of skin cancer can be definitely reduced. This review aims to show the relationship of solar radiation in Brazil with the skin of Brazilian and to highlight the importance of sun protection for this population. With this purpose, it was  made a survey of original articles, literature reviews , Brazilian and international consensus and dermatology books.Keywords: Photoprotection, Skin cancer, Sun exposure, Ultraviolet radiation, D vitamin.

Aim:The objective of this article is to identify and analyze what is known about characteristics in and around the home that support well-being for those with cognitive impairment. This could provide direction for designers of homes in general, but specifically for designers trying to meet the needs of people with cognitive impairment.Background:It has been established that there is a relationship between psychological well-being and a person’s environment. Research also shows that particular design aspects can reduce the impact of cognitive impairment. However, there is limited design expertise in the Australian housing market to create supportive spaces which will help to reduce the impact of the disability for those with cognitive impairment.Method:A literature review was carried out to determine the extent and details of what is known about the relationship of home design and its impact on emotional, psychological, or social well-being for people with cognitive impairment.Conclusions:The study indicates that researchers in various disciplines understand that pragmatic design inputs such as thermal comfort and adequate lighting are important for people with cognitive impairment. In addition, some researchers have shown or surmise that there are other “intangible” designer-controlled elements that have beneficial impacts on people with cognitive impairment. Details of these intangible elements are sparse, and how much they might improve the quality of life for a person with cognitive impairment is not well understood. Further research is required to meet a growing need.

Social scientists have been intrigued by the relationship between generations based on different characteristics. Economists, has been especially interested in measuring intergenerational income elasticity, which looks at the relationship of parents and that of their children when they become adults and gives clue on trends of income inequality. Most of the literature concentrates on the experiences of developed countries and measurement issues. Nevertheless, new studies concerning intergenerational income elasticity is being undertaken in developing countries as the data become increasingly available for these countries. In this vein, there is only one previous study that investigates intergenerational income elasticity for Turkey. Mercan (2012) finds that intergenerational income elasticity is around 0.1 in Turkey, which depicts Turkey as a highly mobile country meaning that children of poor parents have a higher likelihood to have a better income status. However, his study does not depend on a longitudinal dataset, which might make Mercan’s (2012) estimate biased. Following Solon (1992) in using OLS for lower bound and instrumental variable (IV) for upper bound, this study puts forth a new estimate, which relies on a nationally representative and longitudinal dataset for Turkey. The study's estimate for intergenerational income elasticity varies between 0.3 and 0.6, which is much higher than the result of Mercan (2012), indicating that Turkey is a less mobile country than previously foreseen.

This paper analyses the research approach on the relationship between scientificscholar knowledge of the teacher and common previous knowledge of students inschool within the context of teaching, learning and conceptual change in sciences.The paper shows two sections: the first is about conceptual historical development ofthe research question. ln this sense the first question was How the students learnsciences and its transformation into the second, third , fourth and fifth question wasjustified on the light of the reading of the following works, mainly: Piaget, A usubel ,Driver, Vygotsky, and Bachelard, Canguilhem, Kuhn, Lakatos, Popper and othersauthors. The second explains the research question taking into consideration themeaning of the teacher, the pupil and the scientific knowledge in the classroom. Forthis purpose it is necessary to design a conceptual structure in order to analyze therelations, the concepts and the research problems of the teaching, learning andassessment in sciences. The structure shows the relationship of the teacher and thepupilas knowledge relationship. This is the cause why scientific knowledge must beconsidered as the hard core of the science teaching. But scientific knowledge in thiscase is seen as a product of the its historical and epistemological development andthe way as scientific knowledge changes in science is the basis forthinking aboutconceptual change of students in the classroom. The paper ends showing the aimsof the researcher engaged in this approach.

Abstract Study question Does ejaculatory abstinence period in male affect embryological and pregnancy outcomes following fresh embryo transfers in ICSI cycles? Summary answer Shorter ejaculatory abstinence period is associated with lower triploid zygotes rate per ICSI cycle but it does not affect clinical outcomes after fresh embryo transfers. What is known already Lower sperm quality may negatively impact on fertilisation rate and embryo morphokinetic parameters after ICSI and the effect of the ejaculatory abstinence period before semen collection on seminal parameters and sperm quality has been widely reported. However, the impact of ejaculatory abstinence on clinical outcomes is still controversial. WHO (World Health Organization) guideline recommended that abstinence period should be 2–7 days. Even so, there are no larger prospective trials determining the optimal timing for ejaculatory abstinence period for infertile couples. Study design, size, duration This is a single center retrospective observational study of 3,353 fresh cycles from January 2017 to December 2020. Semen analysis was done according to the WHO criteria. Exclusion criteria for this study were frozen gametes and cycles with no retrieved oocytes. Primary outcomes were fertilization rate and triploid zygotes rate. Secondary outcomes were blastulation rate, ongoing pregnancy rate and live birth rate per fresh embryo transfer. Participants/materials, setting, methods The correlation between ejaculatory abstinence and continuous outcomes was evaluated by Spearman’s correlation analysis in order to detect potential non-linear associations. Generalized linear model and logistic regression were used, respectively for continuous and binary outcomes, in order to adjust for confounders such as female age, male age, number of retrieved oocytes, percentage of mature oocytes, infertility causes, seminal volume, sperm concentration and total progressive sperm motility. A p value <0.05 was considered significant. Main results and the role of chance The male mean age was 40.3±5.5 and mean duration of abstinence was 2.9±1.7 days. The mean age of female patients was 38.2±4.0. Higher ejaculatory abstinence period was associated with a higher sperm concentration (Spearman p = 3.1x10–6) but not with a higher total sperm progressive motility. Even so, no significant correlation with EA were observed when considering fertilization rate, blastulation rate, ongoing pregnancy and live birth rate per transfer in analyzed cycles. Triploid zygote rate was positively associated with a higher ejaculatory abstinence period. For the ejaculatory abstinence period of 1 day (n = 64), 2 days (n = 1523), 3 days (n = 1032), 4 days (n = 408), 5 days (n = 174), 6 days (n = 47) and ≥7 days (n = 105) the mean triploid rate was 2.4%, 2.4%, 2.5%, 4.1%, 3.6%, 5.4% and 4.3%, respectively (Spearman p = 9x10–3). Triploid zygote rate was independent of semen volume, concentration and total progressive motility. Limitations, reasons for caution This is a large observational study with a retrospective data collection. Despite our methodological approach, the presence of biases related to retrospective design can not be excluded and it may be a reason for caution. Wider implications of the findings: Our results demonstrate that ejaculatory abstinence period do not affect blastulation, ongoing pregnancy and live birth rates. The current findings discourage an abstinence time longer than 3 days due to its association with a higher abnormal fertilization rate. Trial registration number Not applicable
