Article Synopsis
  • Loneliness and social isolation in the workplace negatively impact employees' mental health and job performance, but the effects of loneliness without distress and solitude are less understood.
  • A survey of 846 full-time employees in Japan found that those experiencing "loneliness with distress" reported higher psychological distress and lower job performance.
  • Both "loneliness without distress" and "solitude" also showed poorer mental health and work engagement, suggesting these conditions should be addressed in workplace mental health initiatives.

A novel chiroptical spectrophotometer, Multichannel (MC)-circular dichroism (CD), which does not require a wavelength scan and provides artifact-free CD spectra in seconds, was developed by solving the incompatibility problem between data acquisition and modulation timescales. The design and instrumentation are compared with the Universal Chiroptical Spectrophotometer (UCS)-1, which can measure artifact-free CD spectra in the solid state. Enantiomeric single crystals composed of achiral components, α-Ni(H O) ・SO , and achiral films with substantial macroscopic anisotropies were measured on both MC-CD and UCS-1 and compared.

Psychotherapy is a learning process. Updating the prediction models of the brain may be the mechanism underlying psychotherapeutic changes. Although developed in different eras and cultures, dialectical behavior therapy (DBT) and Morita therapy are influenced by Zen principles, and both emphasize the acceptance of reality and suffering.

Deracemization extended to racemic-compound-forming systems is demonstrated. We present here the first results of an alternative for the resolution of systems that exhibit a stable racemic compound but also a closely related conglomerate-forming system. If the couples of enantiomers forming the racemic compound and the enantiomers of the stable conglomerate can syncrystallize in mirror-related partial solid solutions, it is possible to deracemize the racemic mixture of mixed crystals to access to a single handedness.

Aim: Previous studies evaluated the association between eating alone and mental health mainly in older people and adolescents. This study aimed to evaluate the association between dinner frequency with others and psychological distress during the COVID-19 outbreak among the Japanese working population.

Methods: Data were acquired from a prospective online cohort study (the Employee Cohort Study in the COVID-19 pandemic in Japan) conducted in February 2021 as a cross-sectional design.

Objectives: This prospective study aimed to examine the association of psychosocial working conditions with adverse reactions after receiving COVID-19 vaccination in a sample of employees in Japan.

Methods: The data were retrieved from an online panel of full-time employees (E-COCO-J). The analysis included participants who were employed and were not vaccinated at baseline (June 2021) but received vaccination at a 4-month follow-up (October 2021).

Unlabelled: We discuss the modeling of temporal dominance of sensations (TDS) data, time series data appearing in sensory analysis, that describe temporal changes of the dominant taste in the oral cavity. Our aims were to obtain the transition process of attributes (tastes and mouthfeels) in the oral cavity, to express the tendency of dominance durations of attributes, and to specify factors (such as sex, age, food preference, dietary habits, and sensitivity to a particular taste) affecting dominance durations, simultaneously. To achieve these aims, we propose an analysis procedure applying models based on the semi-Markov chain and the negative binomial regression, one of the generalized linear models.

Objective: This study aimed to investigate the prospective effects of corporate and organizational workplace measures against COVID-19 on reducing employees` psychological distress during a 12-month follow-up in the COVID-19 pandemic.

Methods: Data were retrieved from an online longitudinal panel survey of full-time employees in Japan, with the 1 survey in March 2020, and the 2 to 6 surveys in May, August, November 2020, February and March 2021, respectively. Seven area-specific workplace measures were assessed using a self-report 23-item scale at the 2 follow-up.

Background: Workplace measures against COVID-19 may prevent the onset of major depressive episode (MDE) in the working population. This 13-month prospective study aimed to investigate the association of the number of workplace measures against COVID-19 and employees' worry about the measures on the onset of MDE during COVID-19 outbreaks in Japan.

Methods: Data were collected from employees by using online questionnaires at baseline (May 2020) and the 7th survey (June 2021).

Objectives: This study aimed to examine the effectiveness of vaccination to improve mental health among employees in Japan based on a prospective study.

Methods: The data were retrieved from the Employee Cohort Study conducted during the COVID-19 pandemic in Japan (E- COCO-J) at T1 (4-10 February 2021) and T2 (22-29 June 2021). Psychological distress was measured by using an 18-item scale of the Brief Job Stress Questionnaire (BJSQ).

Objective: To investigate the prevalences of COVID-19-related workplace bullying and harassment (WBH) and customer harassment among healthcare workers (HCWs) compared to non-HCWs during COVID-19 outbreaks.

Methods: A baseline (March 2020) and follow-up surveys (May, August, and November 2020) were conducted of full-time employees, with an online questionnaire that included items on COVID-19-related WBH and customer harassment. The prevalences were compared between HCWs and non-HCWs using generalized linear models with repeated measures.

The novel coronavirus disease (COVID-19) pandemic has spread throughout the world. Poor mental health has been reported among healthcare professionals responding to COVID-19. However, no study has examined the impact of COVID-19-related workplace bullying or patient aggression on the mental health of healthcare professionals during the COVID-19 outbreak.

Objectives: It is unclear how many workplace COVID-19 preventive measures were maintained during repeated outbreaks. The aim of this study was to investigate a longitudinal change of implementation of workplace preventive measures responding to COVID-19 in Japan.

Methods: An online longitudinal study was conducted using a cohort of full-time employees in Japan, starting in March 2020 (T1), with follow-up surveys in May (T2), August (T3), and November (T4) 2020.

Boron neutron capture therapy (BNCT) is a binary therapeutic method for cancer treatment based on the use of a combination of a cancer-specific drug containing boron-10 (B) and thermal neutron irradiation. For successful BNCT, B-containing molecules need to accumulate specifically in cancer cells, because destructive effect of the generated heavy particles is limited basically to boron-containing cells. Herein, we report on the design and synthesis of boron compounds that are functionalized with 9-, 12-, and 15-membered macrocyclic polyamines and their Zn complexes.

The freshwater snail Lymnaea stagnalis has a long research history, but only relatively recently has it emerged as an attractive model organism to study molecular mechanisms in the areas of developmental biology and translational medicine such as learning/memory and neurodegenerative diseases. The species has the advantage of being a hermaphrodite and can both cross- and self-mate, which greatly facilitates genetic approaches. The establishment of body-handedness, or chiromorphogenesis, is a major topic of study, since chirality is evident in the shell coiling.
