Perspectives of persons in charge regarding support for the health and daily lives of female technical intern trainees who migrate to Japan: a qualitative study.

Objectives: Migrant technical intern trainees who migrate to Japan have become essential to the Japanese labour force, especially in rural areas. Persons in charge of supervising organisations and training coordinators both support the trainees' health and daily lives during their stay in Japan. This support is significant for trainees as it helps them access and interact with Japanese society. This study explored the perspectives of persons in charge of female technical trainees regarding support for the latter's health and daily lives. Materials and Methods: Semi-structured interviews were conducted with 14 persons in charge of female technical trainees, followed by a thematic analysis of the interview data to extract key themes. Results: Four primary themes emerged: fostered beliefs and roles, cultural considerations and health support, language considerations, and concerns about female trainees in relationships. These considerations and support developed solely through experience of persons in charge of female trainees. Additionally, those in charge expressed concerns about trainees being involved in a relationship. However, no specific measures, such as providing female trainees with information, have been taken. Conclusion: Persons in charge of female technical intern trainees need to be provided opportunities to learn about cultural considerations and providing health support for their trainees. Furthermore, the cooperation of health professionals with supervising organisations and training facilities is essential to promote the healthy lives of technical intern trainees. These insights can contribute to the development of an integrated community-based approach to support the health and daily lives of female trainees.

Marital status and post-COVID-19 conditions.

Although studies have investigated the factors associated with psychological post-COVID-19 symptoms, the impact of marital status on symptom development has not been fully determined. This study conducts a questionnaire survey to investigate the association between marital status and the proportion of patients with post-COVID-19 symptoms in 749 cases as valid responses. Depressive state and memory impairment were more frequently seen in the no-spouse group when each symptom was compared according to marital status. Particularly in individuals in the 40s who had minor COVID-19 illness, this trend was noted. Single patients with mild COVID-19 illness may need proactive psychological support.

Interview survey of physical and mental changes and coping strategies among 13 Vietnamese female technical interns living in Japan.

We conducted a case study to assess 1) physical and mental changes; 2) self-assessments of symptoms; 3) coping strategies; and 4) adaptation to physical and mental changes by semi-structured interview survey among Vietnamese female migrant workers working in Japan under the Technical Intern Training Program. We found they experienced female-specific physical changes, and some interns' symptoms worsened because they did not consult anyone about their symptoms. We propose increasing opportunities to learn about possible physical and mental changes caused by migration and to improve health literacy, including prevention, coping, help-seeking, and consultations about health concerns among female technical interns.

Electrochemical aspects of the reverse micelle extraction of proteins.

The mechanism of the solvent extraction of cytochrome c (Cyt c) via reverse micelle formation was studied from an electrochemical point of view. Potentiometric measurements showed that the Galvani potential difference of the oil/water (O/W) interface played a crucial role in the spontaneous extraction of Cyt c with bis(2-ethylhexyl)sulfosuccinate (AOT). However, the dependence of the extraction efficiency on the concentration of an aqueous electrolyte (KCl) could be explained not by the effect of the interfacial potential, but by the change in the interfacial tension (gamma). Electrocapillary measurements showed that the adsorption of AOT anions to the O/W interface resulted in a significant decrease of gamma in a higher potential range, where reverse micelles were formed. The bottom level of gamma in the higher potential range was increased with [KCl]. The lower extraction efficiency for higher [KCl]'s was elucidated by a "size exclusion effect". This was also supported by water-content measurements by the Karl Fisher method.
