Many studies about the health problems of persons with physical disabilities have been performed, however few studies have focused on the life circumstances of persons with physical disabilities. This study aimed to clarify the relationship between stress and the life circumstances of persons with congenital physical disabilities who must use wheelchairs. The participants were 70 individuals who used the services of care workers employed by welfare service business offices. Participants used wheelchairs. In addition, those participants who used a standard manual wheelchair were not able to operate it alone. Participants were required to answer a two-part questionnaire with questions about factors related to basic lifestyle and stress, and about life factors related to the stress of individuals with physical disabilities. No significant relationship between lifestyle and stress was found in either males or females. Most persons with congenital physical disabilities using wheelchairs had some kind of stress in daily life. In particular, significantly more level of stress was found in females (90%) than that in males (65%). Levels of stress according to life factor differed between males and females. The most dramatic gender difference was that the level of stress caused by the mental or mind factor in females was significantly higher than that in males (p < 0.05). Most persons who must use wheelchairs have stress resulting from daily life, and in particular, females experience more mental stress than males.

Effects of Pre-Schooler Lifestyle on the Circadian Rhythm of Secretory Immunoglobulin A

Health 2021年第2期13卷 178-187页

作者： Takaaki Miyake yoshiharu tanaka Haruka Kawabata Shinya Saito Megumi Oda Faculty of Liberal Arts and Sciences Osaka Prefecture University Osaka Japan Graduate School of Health Sciences Okayama University Okayama Japan

Assuming that secretory immunoglobulin A (s-IgA) in pre-schoolers is influenced by wake-up time, bedtime, sleeping duration and activity, the current study examined the influence of basic pre-schooler lifestyle on the circadian rhythm of s-IgA. We conducted a questionnaire survey on lifestyle and measured steps, heart rate and salivary s-IgA in 44 pre-schoolers aged 4 or 5 years old. Saliva was collected over 2 days at six time points: bedtime, upon waking up, upon arriving at nursery school, before lunch, after lunch and upon going home. To obtain relatively reliable s-IgA values, the s-IgA concentration/total protein concentration ratio (referred to as s-IgA/T.P.) was calculated. Relationship between the s-IgA/T.P. and heart rate, steps, wake-up time, bedtime and sleeping duration was then examined using Pearson’s correlation coefficient. Accordingly, pre-schooler lifestyle had the following effect on circadian rhythm of s-IgA: 1) s-IgA/T.P. values were higher upon waking up than at other measurement time points;2) pre-schoolers with considerable physical activity had high s-IgA/T.P. at bedtime and upon waking up;and 3) pre-schoolers with long sleeping durations and early bedtime had high s-IgA/T.P. upon waking up. Thus, our results confirmed that pre-schoolers’ lifestyle habits, such as bedtime, sleeping duration, physical activity, had an effect on the circadian rhythm of s-IgA.

He, CO_2, O_2, N_2, CH_4, C_3H_8, and t-C_4H_(10) gas permeability coefficients and diffusion coefficients of poly(4-methylpentene-1) (PMP) with various degrees of crystallization were plotted against the degree of crystallization. The plotdemonstrated a linear relationship. The gas permeability coefficient and diffusion coefficient of pure amorphous and purecrystalline PMPs were evaluated by a linear extrapolation to zero and 100% crystallinity, respectively. The relationshipbetween the diffusion coefficient of crystalline parts of PMP and the kinetic diameter of penetrant gases was *** polystyrene (SPS) could exist as δ form crystals complexed with organic solvents such as benzene, toluene,xylene, and ethylbenzene. The mesophase of SPS is prepared by annealing the δ form of crystalline complexes at a certaintemperature for 1 h. The desorption of solvent during annealing almost does not result in changes of both the conformation ofbackbone chains and the crystal lattice. We could prepare the mesophase containing molecular cavities with the size andshape of the organic solvent molecules. The mesophase could sorb the same solvent after the manner of Langmuir sorption atlow vapor pressure range while this would not be the case for solvents of different size and shape. This suggests a molecularrecognition of organic solvent, and mesophase SPS might be useful for separation membrane and adsorptive material.

Fracture theory based on the concept of characteristic fracture length of materials

引用

Science China(Physics,Mechanics & Astronomy) 2009年第12期52卷 2041-2046页

作者： MUTOH yoshiharu Department of Safety Engineering Nagaoka University of Technology

Fracture theory is a classic,but not a well-dealt with,difficulty in solid mechanics. This paper has proposed the concept of characteristic fracture length of materials from the fact that fracture happens with area failure rather than point failure in materials. A unified theory is then proposed,which can be applied both to smooth and defected materials (whether with micro or macro defects). Brittle fracture tests with specimens of different sizes of holes are carried out to examine the fracture theory. It is found that the fracture stresses obtained by experiments agree well with those predicated by the presented fracture theory. Though the brittle fracture is the focus of the paper,the concept of characteristic length can be easily extended to fatigue or other failure problems.

PREDICTING RELEVANT EMPTY SPOTS IN SOCIAL INTERACTION

引用

Journal of Systems Science & Complexity 2008年第2期21卷 161-171页

作者： yoshiharu MAENO Yukio OHSAWA Graduate School of Systems Management Tsukuba University School of Engineering University of Tokyo

An empty spot refers to an empty hard-to-fill space which can be found in the records of the social interaction, and is the clue to the persons in the underlying social network who do not appear in the records. This contribution addresses a problem to predict relevant empty spots in social interaction. Homogeneous and inhomogeneous networks are studied as a model underlying the social interaction. A heuristic predictor function method is presented as a new method to address the problem. Simulation experiment is demonstrated over a homogeneous network. A test data set in the form of market baskets is generated from the simulated communication. Precision to predict the empty spots is calculated to demonstrate the performance of the presented method.

DATA CRYSTALLIZATION APPLIED FOR DESIGNING NEW PRODUCTS

引用

Journal of Systems Science and Systems Engineering 2007年第1期16卷 34-49页

It is only the observable part of the real world that can be stored in data. For such incomplete and ill-structured data, data crystallizing aims at presenting the hidden structure among events including unobservable events. This is realized by data crystallization, where dummy items, corresponding to potential existence ofunobservable events, are inserted to the given data. These dummy items and their relations with observable events are visualized by applying KeyGraph to the data with dummy items, like the crystallization of snow where dusts are involved in the formation of crystallization of water molecules. For tuning the granularity level of structure to be visualized, the tool of data crystallization is integrated with human＇s process of understanding significant scenarios in the real world. This basic method is expected to be applicable for various real world domains where previous methods of chance-discovery lead human to successful decision making. In this paper, we apply the data crystallization with human-interactive annealing （DCHA） to the design of products in a real company. The results show its effect to industrial decision making.
