Plateauing of Children's Height in Japan and South Korea : Unhealthy Eating Habits

When discussing the determinants of height, most studies have tried to identify changes in food consumption, particularly animal protein, in terms of simple per capita averages of population, without explicit attention on age/cohort identification of children in growing ages. In modern societies, where generational effects are more prevalent in individual food consumption, greater efforts to identify changes in individual consumption by age/cohort in the populations are crucial. Such analysis shows that younger generations have turned away from fruit in recent decades in Japan, while the older generations in their 50s to 60s still eat reasonable amounts of fresh fruit today. In order to determine major correlates of children's height in food consumption, either cross-sectionally or over time, explicit efforts are required to determine changes in per capita food consumption by children, as distinct from mere per capita consumption of the full population. Family Income and Expenditure Surveys by Japan's Statistics Agency started to provide data classified by age groups of household head (HH) in the 1970s. One can estimate per capita consumption of selected products by household members by age, with statistical precision. Statistics Korea followed suit. The author statistically refined the statement, "steering away from fruit by the young" used in the Japanese government White Paper on Agriculture, 1994, to surmise that radical reduction in fruit consumption by Japanese children in the 1980s-90s should be responsible for the plateauing of children's height in the 1990s. Children in South Korea started to reduce consumption of vegetables appreciably in the early 1990s and further continued this tendency to eat only about 10% of vegetables eaten by the middle aged adults in their 50s in the end of the 2010s. Children in Korea grew much faster than their Japanese peers to outgrow them by 3.0 cm in the early 2000s and then ceased to grow any taller. The drastic reduction of vegetables by the young should have something to do with the cessation of height growth, in the midst of economic expansion in South Korea.departmental bulletin pape

Anchorless cell surface proteins function as laminin-binding adhesins in Lactobacillus rhamnosus FSMM22

application/pdfAnchorless cell surface proteins (CSPs) were extracted with 1 M lithium chloride solution from Lactobacillus rhamnosus FSMM22. Loss of the anchorless CSPs resulted in a 2-fold decrease in FSMM22 cells bound to a constitutive extracellular matrix glycoprotein, laminin, in vitro. DNA-binding protein HU, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase and 30S ribosomal protein S19 (RpsS) were identified by mass spectrometry in the extract as laminin-binding adhesins. Among the four proteins, RpsS was immunohistochemically confirmed to exist on the cell surface. Our findings strongly suggest that anchorless CSPs can enhance bacterial adhesion to the host.journal articl

Strengthening the evidence for seasonal intertidal exploitation in Mesolithic Europe and new insights into Early Holocene environmental conditions in the Bay of Biscay from the oxygen isotope composition of Phorcus lineatus (da Costa, 1778) shells

Unidad de excelencia María de Maeztu CEX2019-000940-MMarine molluscs have been exploited by human societies since prehistoric times. Such practices have often resulted in large accumulations of shell remains in archaeological sites that offer unique information on biological, ecological and cultural aspects of human interaction with coastal systems in the past. In this study, stable oxygen isotope (δ18O) analysis was carried out on archaeological shells of Phorcus lineatus (da Costa, 1778) from the Mesolithic shell midden site of J3 (northern Iberian coast) to determine the seasonality of intertidal collection. The results indicate a consistent pattern of winter exploitation, supporting the emerging view that collections were governed by cost-benefit and management principles that are now widespread documented in other coastal Mesolithic sites in Europe. The consistent seasonal collections of P. lineatus during colder months can be taken as evidence of specie-specific management strategy to optimize yield while preserving local populations for future exploitation. Our results reinforce the view that European hunter-gatherers developed ecological knowledge on specific animal resources that persisted over large geographic areas. Additionally, from a palaeoenvironmental perspective, the sea surface temperatures (SST) inferred from δ18O values derived from mollusc shells (SSTδ18O) indicate that coastal marine waters during the Early Holocene in the southern Bay of Biscay were warmer than those observed today. These environmental conditions are evaluated in relation to changes in insolation and ocean currents over time

Mathematics and Chemistry Interdisciplinary Joint Research and the Fukui Project VI

publisherThis is the sixth part of the series of articles that records and further develops essentials of the Mathematics and Chemistry Interdisciplinary Symposium 2013 Tsuyama, whose main themes were symmetry, periodicity, and repetition. The symposium was held on April 5th and 6th in Tsuyama city, Okayama, Japan, in conjunction with the Fukui Project and was devoted to the memory of the late Professor Kenichi Fukui (1981 Nobel Prize) who initiated the project. The present series also provides challenging cross-disciplinary problems which are directly related to the Fukui conjecture and to recent carbon nanotube research. Most of these problems are formulated using mathematical language of unique factorization domain (UFD) and related notions, which are not well known among chemists despite the importance of these notions in elucidating additivity and high-speed asymptotic phenomena in molecules having many repeating identical moieties.departmental bulletin pape

Reversible Implementations of Irreversible Component Transforms and Their Comparisons in Image Compression

Reversible color component transforms derived by the LU factorization are briefly described. It is possible to obtain an reversible implementation to a given component transform, even if the original transform is irreversible. Some examples are presented and their performances are compared in image compression.journal articl
