Multi-method characterization of soda-lime glass corrosion : Part 2. Corrosion in humidity Report of the International Commissionon Glass (ICG) Subcommittee of Technical Committee 19 "Glass Surface Diagnostics"

As-received and cleaned soda-lime glass surfaces corroded in high relative humidity of 95 % at a temperature of 60 °C for times up to one week are investigated by means of TOF-SIMS, SNMS, XPS, NRA, ERD, RBS, GIXR, AFM, SEM and optical microscopy. Distinct differences in the corrosion behavior are observed for as-received and cleaned glass surfaces. Changes in element concentration in the glass interface and in the topography of the glass surfaces are described for different exposure times in humidity. They are combined with variations in density of the modified surface layer. Cleaning before the corrosion treatment drastically reduces degradation; cleaning after the corrosion treatment can restore the surface

[研究ノート] 高齢者集落における社会的紐帯と健康状態の関連への文化人類学からのアプローチ：秋田県男鹿市A地区B集落での予備調査から

要旨：保健分野のソーシャル・キャピタル研究では、ソーシャル・キャピタルの内実が地域毎に異なるにも関わらずその内実が解明されず、またソーシャル・キャピタルと健康の因果関係が明らかにされないという２つの問題点がある。本研究では、対象社会の社会構造の特徴を精査した上で、それが集団レベルの健康状態と結びつくメカニズムの解明を目指す文化人類学の手法を構想した。2015年４月から秋田県男鹿市Ａ地区の住民を対象に行った現在までの予備調査では、対象地域住民の間で社会的紐帯が強く、その背景に親族組織や農事勉強会などの社会組織が関連するという手がかりを得た。本稿では現在までに得た予備調査データを参照しつつ本研究の構想を示す。Abstract：Many studies have been conducted using the concept of social capital in the fi eld of health recently. These studies typically have two problems. The first is that they do not pay close attention to the actual situation of social capital, although there are real diff erences amongst communities. The second is that they do not discuss causation between social capital and health status. Thus, in this study, we utilize a cultural anthropological approach to investigate the relationship between the social structure and the health status of a given group, based on a survey of the characteristics of social structure in the subject community. The participants are located in the (A) district of Ogacity, Akita, where we have been conducting fieldwork since April, 2015. According to our preliminary fieldwork, we have discovered results, which suggest that the connection amongst the people was strong in the subject community, which has a relationship with social organizations such as a kin group, agricultural study meeting, and so on. In this article, we present our research framework based on data from our preliminary fieldwork

Multi-method characterization of soda-lime glass corrosion : Part 1. Analysis techniques and corrosion in liquid water Report of the International Commission on Glass (ICG) Subcommittee of Technical Committee 19 "Glass Surface Diagnostics"

Corroded soda-lime float glass surfaces prepared in water (room temperature and 60 °C) or air (relative humidity of 95 %, 60 °C) for different times are invesdgated by means of SIMS, SNMS, XPS, NRA, ERD, RBS, GIXR, AFM, SEM, light microscopy and scratch testing. The corrosion effects are studied for as-received and cleaned glass surfaces. Changes in the dement concentration in the glass interfaces with the immersion time in water are described. They are combined with variations in density of the surface layer which exhibits plastic deformation behaviour. Inhomogeneous corrosion leads to changes in the topography and an increase in surface roughness

Reduced morning cortisol concentration in saliva was associated with obesity: evidence from community-dwelling adults in Papua New Guinea

Objectives: This study investigated morning salivary cortisol concentration in relation to total body fat composition among community-dwelling Papua New Guinean adults. Methods: In addition to demographic and anthropometric measurements, saliva was collected in a single morning from 478 residents in Eastern Highlands Province and Madang Province. Results: After adjusting for age, region, and occupation, the morning salivary cortisol concentration was significantly negatively correlated with body mass index among men (B = -0.01, P < 0.05) and women (B = -0.013, P < 0.05), and waist circumference (B = -0.007, P < 0.05), waist-to-hip-ratio (B = -1.214, P < 0.05), and subscapular-to-triceps skinfold-thickness ratio (B = -0.045, P < 0.05) among men. Men with total or abdominal body fat mass known for elevated risk of non-communicable diseases displayed lower cortisol compared to men without such risk. Conclusions: Papua New Guinean adults with increased accumulation of body fat showed reduced cortisol concentration in morning saliva
