Abstract
The purpose of this study is to investigate an objective method of evaluating the tactile comfort of blankets by a method of connecting the mechanical parameters of blankets to subjective evaluation. The two methods are preliminarily investigated as follows: (1) Transformation equations for the fabric hand of suiting, KN‐101‐W for primary hand values and KN‐301‐W for THV, are applied, with the mean and standard deviation applied to these equations replaced with new values for the blanket population. (2) A new prediction equation is constructed for deriving THV directly from the mechanical parameters and thermal properties. The prediction accuracy of method (2) is a little higher than that of (1). The durability of blankets during repeated use and repeated dry cleaning determined by the initial performance of blankets is also investigated.
We predict the compression properties of blankets from the blanket structure and the fiber bending property. This study applies to the theory developed originally for the…
Abstract
We predict the compression properties of blankets from the blanket structure and the fiber bending property. This study applies to the theory developed originally for the compressive deformation of carpets by Kimura, Kawabata and Kawai in 1970 to blankets. As a result, we found that the initial compression properties of Mayor and New Mayor blankets could be predicted by the compression theory.

Abstract
Relationships have been investigated between subjective pressure sensation and objective pressure measured, for knit garments of different sizes and fabrics with different extensibilities. Fechner's logarithmic law is used to investigate the relations. Equations are obtained for describing the Psychophysical mechanism of clothing pressure perception under certain conditions. Objective pressure measuring had high predictive power with regard to subjective pressure sensation only under those conditions. Wearing pressure comfort has a negative correlation with feelings of fetter, scratchy, heavy and pressure, and has a poor correlation with feelings of softness and smoothness. Using factor analysis with principal factor solutions and rotated by the Varimax method, we obtained factor matrices.

Abstract
Since the advent of Honda’s ASIMO and Sony’s AIBO, robot fever has broken out in the general public of Japan. However no significant business has yet materialized, except in the pet robot business in the toy industry. On the other hand serious basic research for humanoid robots is going on which may have an impact on the future of robotics. This report describes the current status of Japanese humanoid fever and its reality.

Abstract
Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Abstract
The handling of initially disordered mechanical parts with a robot manipulator needs some procedure for orientating these parts. A simple microprocessor‐controlled TV‐sensor which enables an industrial robot to perform this function by measurement of orientation and position of the parts is described. Constraining the parts to a finite number of stable positions by mechanical devices preceding the visual sensor, restriction to binary images, processing of only a few information carrying TV‐lines and a simple recognition algorithm lead to an easily programmable microprocessor‐controlled visual sensor which accomplishes all practical requirements of flexibility, high speed, low memory size and low costs.

Abstract
Purpose
Gamma-aminobutyric acid (GABA) is a four-carbon and nonprotein amino acid, made by various microorganisms, especially lactic acid bacteria (LAB) and probiotics. GABA has various physiological roles, for instance, insomnia, depression, hypotensive activity as well as diuretic effects. The production of GABA-based foods is a favorable result from GABA’s biological and functional properties. The purpose of this study is to investigate different methods of improving GABA production in probiotics and LAB to select the superlative method and bacterial strain.
Design/methodology/approach
In this review paper, all articles from five electronic databases containing Google Scholar, Web of Science, PubMed, Scopus and Science Direct were considered from 2000 to January 11, 2023, with keywords “Optimization” OR “Enhance” OR “Increase” AND “Gamma-aminobutyric acid” OR “GABA” AND “Probiotics” OR “Lactic acid bacteria” and selected according to the purpose of the study.
Findings
It seems that among all the investigated methods, an effective fermentation procedure with optimal conditions including fermentation medium, 5 L; glutamic acid, 295 g/L; incubation temperature, 32°C; inoculum, 10% (v/v); and agitation, 100 rpm, after 48 h of fermentation led to producing 205,800 mg/L of GABA from the effective bacterial strain Lactobacillus brevis NCL912.
Originality/value
With a simple but optimized fermentation, L. brevis NCL912 can be used for the efficient GABA production in the pharmacy and food factories.

Abstract
Purpose
The purpose of this paper is to analyze factors associated with post-traumatic stress disorder (PTSD) among elderly who live in a post-earthquake area.
Design/methodology/approach
This was a cross-sectional study involving 152 elder people who survived the disaster and were selected conveniently. The study was conducted in two worst-affected districts of Lombok Utara regency. PTSD was diagnosed using a modified version of the Clinician-Administered PTSD Scale version 5 (CAPS-5). The demographic data were assessed using a self-developed questionnaire consisting of 13 items. All data were analyzed by descriptive analysis, χ2 test and binary logistic regression with p<0.05.
Findings
Out of the 152 elder people, 91 (59.9 percent) suffered PTSD. Intrusion symptoms were the most common symptoms experienced by the respondents (94.1 percent). The factors associated with the PTSD in the elderly after the earthquake were having chronic illnesses (OR=2.490; 95% CI=1.151–5.385), public health center utilization (OR=2.200; 95% CI=1.068–4.535) and occupational status before the disaster (OR=2.726; 95% CI=1.296–5.730). These findings highlight that individual factors and access to health care services remain an important aspect of stress identification among the elderly following the disaster event.
Social implications
Elder people constitute a vulnerable group that is often forgotten and neglected during post-disaster recovery, though they have potentially higher psychosocial distress than younger age groups. This study was conducted to raise awareness about mental health problems suffered by the elderly.
Originality/value
This is the first study to apply CAPS-5 to assess PTSD among Indonesian elderly people following a natural disaster. This paper also provides insights that can be used by governments and other relevant parties to address PTSD problems suffered by many elderly people in a post-disaster area.
