The study by Kametaka and Inuo has identified the original source for the translation of the home management book Kanaikokoroegusa Ichimei-hokaho (1876) as The Book of Household Management (1861). However, there are many discrepancies between the two. Therefore, I scrutinized both books as well as Beeton’s Every-Day Cookery and Housekeeping Book (1872). The results show that the contents of Kanaikokoroegusa were almost completely consistent with items 1 through 174 of the first half of “Philosophy of Housekeeping” in Beeton’s Every-Day Cookery and Housekeeping Book. Thus, I identified this book as the original source of Kanaikokoroegusa. Additionally, this study established that its translator, Hozumi Seiken, while a pioneer in the translation of works on Western culture and household management techniques at the dawn of the Meiji era, struggled to find appropriate Japanese terminology for the translation.

  In recent years, the living environment of university students has become increasingly diverse, and residential patterns and dietary content have changed significantly. Several studies have examined the association between residential patterns and habitual dietary intake, but their results have been inconsistent. In this study, we used a meta-analytic approach to investigate whether energy, nutrient, and food group intakes differ between students who lived alone and those who lived at home. A comprehensive search was conducted using Google Scholar, CiNii and Ichuushi web databases to identify any relevant studies published until November 2023. In this meta-analysis, the results of a screening included 10 observational studies with a total of 1,322 subjects. The pooled analysis for the random-effects model showed that energy (MD = -241.19, 95%CI -337.42 to -144.97, p < 0.00001, I² = 74%), protein (MD = -9.42, 95%CI -13.12 to -5.72, p < 0.00001, I² = 73%), fat (MD = -8.19, 95%CI -11.86 to -4.52, p < 0.0001, I² = 69%), and carbohydrate (MD = -17.34, 95%CI -31.43 to -3.25, p = 0.02, I² = 79%) intakes were significantly lower in students who lived alone than in those who lived at home. These results suggest that residential patterns may strongly affect habitual dietary intake among college and junior college students. However, these results should be interpreted with caution because there are few reports in peer-reviewed journals or cohort studies.

  This study aimed to investigate the α-glucosidase inhibitory effect and postprandial blood glucose level suppressing effect of Japanese black tea. Of the 19 Japanese black tea species, 15 showed an inhibition rate of α-glucosidase activity of ≥ 50%. A positive correlation was observed between the inhibition rate of α-glucosidase activity and the suppressive effect on postprandial blood glucose levels. Additionally, no significant difference was observed in the postprandial blood glucose levels of 29 healthy women after consuming Japanese black tea and water. However, among the 15 subjects with tendencies for postprandial blood glucose elevation, the results demonstrated significantly lower blood glucose levels 30 minutes after a meal, when levels typically peak, when consuming Japanese black tea compared to water. These findings indicate that Japanese black tea has an inhibitory effect on α-glucosidase activity. Furthermore, drinking Japanese black tea with a meal has the potential to suppress the increase in postprandial blood glucose levels in individuals prone to elevated blood glucose levels.

  In this study, three types of 36 GG bare jersey were knitted to achieve the same basis weight as closely as possible, and four types of underwear samples with varying moisture absorbency and waviness index Wa, indicating the unevenness of the knitted fabric on the skin side and the outer surface, were produced.

  Young men conducted hearing evaluations and measurements of the garment’s internal environment in a hot environment (Environment I) and a thermo-neutral environment (Environment II). The relationship between the results of the wearing test and the sample characteristics is discussed and summarized below as a guideline for the design of desirable knitted fabrics for summer undershirts.

  1) Based on the results of the wearing evaluation, the sensation of wearing the undershirt was summarized into two factors: Skin contact factor and Thermal factor.

  We found that the Skin contact factor and the Thermal factor contributed to the overall rating in Environment I, and the Skin contact factor in Environment II. In addition, the ability to discriminate skin contact was observed to be easier in Environment II than in Environment I.

  2) For comfort in wearing summer undershirts, both skin contact and heat-moisture transfer must be considered.

  To improve skin contact, reducing the waviness index Wa, which indicates surface unevenness, is desirable. For better heat and moisture transfer, increasing air permeability is desirable.
