通電による異常増殖した藻類の除去

This study investigated a method of removing algae by energizing a metal electrode plate set in water containing abnormally proliferated algae. As algae have negative charge in water, they migrated to the anode by electrophoresis in an electric field. Combining with cations eluting from the anode, especially aluminum ions, the algae formed cohesive floc and then adhered on the anode surface without returning into the water. In the continuous flow apparatus, algae were removed at high removal rate by taking out the algae adhered on anode regularly. It was shown that the electrochemical method can efficiently remove algae from water

A promising strategies for reducing the danger of SARS-CoV2 transmission during dentistry and medical procedures

The leaves of Stevia The COVID-19 epidemic has presented serious difficulties for healthcare professionals, especially those working in dentistry and medical facilities. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, is a high-risk infection in hospital settings since it is known to spread via respiratory droplets and aerosols. The purpose of this review paper is to determine whether preprocedural mouthwashes significantly lower the risk of SARS-CoV2 transmission during dental and medical procedures. in addition, antiseptics including Povidone-iodine, CPC, Benzalkonium Chloride, and Aromatic oils may indeed be capable of eliminating SARS-CoV2 by focusing on the virus's lipid envelope, that according in vitro study, as well as clinical experiments indicate that preprocedural mouthwashes potentially help to reduce intraoral viral load and infectivity in COVID-19 patients, but more research is required to verify this. Other infection control methods, such as PPE, high-volume evacuation (HVE), and air filtration, can also assist in minimizing SARS-CoV2 transmission during operations. The RT-qPCR alone is insufficient to determine the effectiveness of preprocedural mouthwashes against SARS-CoV2 transmission. Future research should also take into account employing supplementary techniques to evaluate the effectiveness of preprocedural mouthwashes, such as determining the virus's survival in cell cultures or using animal models to research the virus' transmission. Further research is needed to determine the best combination of infection control measures to reduce SARS-CoV2 transmission in healthcare settings, but preprocedural mouthwashes may be a simple, low-cost strategy to reduce transmission risk during dental and medical procedures, especially in high-risk patients

Psychologists’ dilemmas in career counselling practice

In this study, we explored main dilemmas psychologists face in career counselling in two main professional settings: employment and education. Participants included 24 experienced Portuguese psychologists, working in employment (n = 14) and educational (n = 10) settings. We used consensual qualitative research to conduct and analyse semi-structured interviews. Results revealed dilemmas’ in five domains: neutrality, assessment, dual loyalty, role boundaries, and confidentiality, with the typical dilemma in the domain of neutrality. Differences between groups were found in the domains of dual loyalty and role boundaries.Dans cette étude, nous avons exploré les principaux dilemmes rencontrés par les psychologues dans le conseil en orientation dans deux milieux professionnels centraux: le placement et l’éducation. Parmi les participants figuraient 24 psychologues portugais expérimentés travaillant dans des contextes de placement (n = 14) et d’éducation (n = 10). Nous avons utilisé la recherche qualitative consensuelle pour mener et analyser les entretiens semi-structurés. Les re´sultats ont révé lé des dilemmes dans cinq domaines: la neutralité, l’évaluation, la double loyauté, les limites du rôle, et la confidentialité, avec le dilemme typique dans le domaine de la neutralité. Les différences entre les groupes ont été identifiees dans les domaines de la double loyauté et les limites du rôle.In dieser Studie untersuchten wir die hauptsä chlichen Dilemmata, mit denen Psychologen in der Berufsberatung in zwei wesentlichen professionellen Einrichtungen konfrontiert sind: Beruf und Bildung. Zu den Teilnehmern geho ¨rten 24 erfahrene portugiesische Psychologen, die in Einrichtungen von Beruf (n = 14) und Bildung (n = 10) arbeiteten. Wir verwendeten einvernehmliche qualitative Forschung um semi-strukturierte Interviews durchzufu¨hren und zu analysieren. Die Ergebnisse zeigten Dilemmata in fünf Bereichen: Neutralität, Beurteilung, doppelte Loyalität, Rollengrenzen und Vertraulichkeit, mit dem typischen Dilemma in der Domäne der Neutralität. Unterschiede zwischen den Gruppen wurden in den Bereichen der doppelten Loyalität und Rollengrenzen gefunden

Humanistic psychotherapy research 1990-2015 : from methodological innovation to evidence-supported treatment outcomes and beyond

Over the past twenty five years, humanistic psychotherapy (HP) researchers have actively contributed to the development and implementation of innovative practice-informed research measures and coding systems. Qualitative and quantitative research findings, including meta-analyses, support the identification of HP approaches as evidence-based treatments for a variety of psychological conditions. Implications for future psychotherapy research, training and practice are discussed in terms of addressing the persistent disjunction between significant HP research productivity and relatively low support for HP approaches in university-based clinical training programs, funding agencies and government-supported clinical guidelines. Finally, specific recommendations are provided to further enhance and expand the impact of humanistic psychotherapy research for clinical training programs and the development of treatment guidelines
