Is self-administered DMPA an answer to contraception access in the post-Roe era?

Consider prescribing self-administered subcutaneous depot medroxyprogesterone acetate (DMPA) for contraception instead of provider-administered DMPA. Self-administration improves contraception continuation rates without notable increases in pregnancy or adverse effects.Lindsay Nakaishi, MD, MPH, DipABLM; Gregory Castelli, PharmD, FCCP, BCPS, BC-ADM, CDCES, (UPMC St. Margaret Family Medicine Residency Program)Includes bibliographical reference

PIV measurement of internal flow in mini centrifugal pump

The diameter of the ventricular assist pump and cooling pump for electrical devices like servers is about a dozen millimetres and these kinds of pumps belong to the mini pump. The internal flow condition of the mini centrifugal pump has to be clarified because there are so many types of mini pumps according to special specifications and shapes. Therefore, in this research, an open impeller was adopted as a mini centrifugal pump with 55mm impeller diameter in consideration of reduction in impeller manufacturing cost and its internal flow was investigated. Since the outlet angle of the test impeller is large, the maximum efficiency flow rate moves to a large flow rate and the relatively high head and efficiency were obtained in large flow rate region. In the present paper, the velocity and vorticity distribution near the volute tongue are shown and the internal flow in the mini centrifugal pump is clarified based on the PIV measurement results

On The Usage of Intransitive and Transitive Verb Pairs and its Relationship to Instruction : An Analysis of Japanese Textbooks for Beginners

In this study, I investigated the usage of transitive and intransitive verbs that appears in several Japanese textbooks for beginners after reviewing the grammatical characteristics of intransitive and transitive verb pairs. As a result, I found out the inappropriateness of some of the explanation for intransitive and transitive verbs to be fundamental grammatical knowledge. Learners need to learn intransitive and transitive verbs not only grammatically but also pragmatically to be natural in Japanese. Pragmatic usage should be taught in more advanced level. However, the rules in some current Japanese textbooks for beginners may inhibit the acquisition of pragmatic and communicative usage of transitive and intransitive verbs

An introductive study on education and training in enterprise in the field of adult education in Japan

The aim of this article is to confirm the position of education and training in enterprise in the field of the study on adult education in Japan. We will mainly examine "The Theory of Social Education" written by Shirou Kurauchi which has been playing a great role in the field on the syudy of adult education. In his argument, education and training in enterprise is a typical model of the theory of adaptation. In this article we will discuss about the concept of adaptation and self-development

Theory of Career Development; Its Concept and History

"Career development in organization" has been an important concept in education and training in enterprise since the 1960s in Japan. The essence of career development in organizations is to focus on the interaction between an individual and an organization. The problem on the side of the individual is how to match his/her needs throughout his/her entire career or life history with those of the organizaion. Although there have been a few articles concerning development in organizations, they only discuss practical elements and do not deal with the theoretical aspect. However, in recent years, there has been a growing trend of showing more interest in individual growth and development in the field of the study on education and training in enterprise. The purpose of this paper is to review and examine the studies on career development from a viewpoint of individual growth and development. Firstly, we will clarify the concept and history of career development. Secondly, we will examine the vocational development theory proposed by Super,D.E. along with the theory of career development in organizations suggested by Schein,E.H. We will then discuss some of the problems and issues concerning career development

Fear of falling and hip muscular strength in independent older adults of the community

The fear of falling can cause older adults to develop strategies that alter the semi-static and dynamic balance, predisposing them to increased risk of falling. The muscular function of abductors and adductors plays an important role in maintaining postural stability. However, it is unknown whether older people with fear of falling have greater impairment in hip muscular function. Thus, the objective was to compare the isometric peak torque (PT) of hip abductor and adductor muscles among older adults with and without fear of falling. Participants were divided into two groups: with (n=81) and without (n=81) fear of falling. The PT of hip abductors and adductors was obtained with isokinetic dynamometer (System 4 Pro, Biodex, New York, USA). The PT groups were compared using general linear model univariate, adjusted for covariates age, sex, body mass index, physical activity level and history of falls, using the SPSS 17.0 software, with a significance level of 5%. No difference was found between the PT of hip abductor and adductor and the groups after univariate analysis with adjustment. We observed that older people with fear of falling have no muscle function loss of the hip stabilizers when compared with subjects without fear of falling.El miedo a caerse puede hacer que los ancianos desarrollen estrategias de alteración del equilibrio semiestático y dinámico, predisponiéndolos a un mayor riesgo de caídas. La función muscular de los abductores y de los aductores de cadera juega un papel importante en el mantenimiento de la estabilidad postural. Sin embargo, no se sabe si los ancianos con miedo a caerse tienen un mayor deterioro en la función muscular de la cadera. Por lo tanto, el objetivo fue comparar el torque máximo (TM) isométrico de los músculos abductores y aductores de cadera entre los ancianos con miedo y sin miedo a caerse. Los participantes se dividieron en dos grupos: con miedo a caerse (n=81) y sin (n=81) miedo a caerse. El TM de los abductores y aductores de cadera se obtuvo mediante la utilización del dinamómetro isocinético (System 4 Pro, Biodex, Nueva York, EE.UU.). La comparación del TM de los grupos se realizó mediante un modelo lineal general univariado, ajustado por covariables edad, género, índice de masa corporal, nivel de actividad física e historial de caídas, utilizando el software SPSS 17.0, con nivel de significancia del 5%. No hubo diferencias entre el TM del abductor y del aductor de cadera entre los grupos tras el análisis univariado con ajuste. Se observó que los ancianos con miedo a caerse no presentaron daños en la función muscular de los estabilizadores de la cadera en comparación con los ancianos sin miedo a caerse.O medo de quedas pode fazer com que o idoso desenvolva estratégias que alteram o equilíbrio semiestático e dinâmico, predispondo-o a um risco aumentado de cair. A função muscular dos abdutores e adutores de quadril tem importante papel na manutenção da estabilidade postural. Entretanto, não se sabe se idosos com medo de cair apresentam maior comprometimento na função muscular do quadril. Assim, o objetivo foi comparar o pico de torque (PT) isométrico dos músculos abdutores e adutores de quadril entre idosos com e sem medo de quedas. Os participantes foram divididos em dois grupos: com (n=81) e sem (n=81) medo de quedas. O PT dos abdutores e adutores de quadril foi obtido com dinamômetro isocinético (System 4 Pro, Biodex, Nova York, EUA). A comparação do PT dos grupos foi realizada por meio de modelo linear geral univariado, ajustado pelas covariáveis idade, sexo, índice de massa corporal, nível de atividade física e histórico de quedas, utilizando o software SPSS 17.0, com nível de significância de 5%. Não houve diferença do PT abdutor e adutor do quadril entre os grupos após análise univariada com ajustamento. Observou-se que idosos com medo de quedas não apresentam prejuízos na função muscular dos estabilizadores de quadril quando comparados a idosos sem medo de quedas
