Livelihood and Care of the Elderly: Determinants of Public Attitudes in Japan

This study analyses public attitudes towards the degree of government involvement in ensuring the livelihood and care of the elderly in Japan. Using four waves of individual-level annual data from the Japanese General Social Survey collected over the period 2000-2005, we estimate ordered logit models with various explanatory variables based on the socio-demographic, economic, political, and social background of the respondents. Many significant factors are common for both livelihood and care specifications, their effects being qualitatively the same and in line with our prior expectations. The estimation results also show positive coefficients of year intercept dummies, implying an increase in support of a government-based system over time. Further investigation shows that this trend is caused by those who favour government redistribution policies becoming increasingly more consistent in their support for a government-based social security system in Japan.Livelihood of elderly, care of elderly, public attitudes, aging societies, Japan

Comparing Public Attitudes Towards Providing for the Livelihood of the Elderly in Two aging Sodieties: Germany and Japan

This paper studies attitudes about who should provide for the livelihood of the elderly in two aging societies, namely Germany and Japan. Applying an ordered logit model to individual data from representative public opinion surveys, it is analysed which socio-demographic, economic or political variables help to explain people’s attitudes on whether the government or individuals should be responsible for the livelihood of the elderly. We find that while higher income makes people more inclined towards the individual option, age is found to do the opposite in both countries. We conjecture that this age effect is related to the level of knowledge about the current situation of the public pension system. We also find that the part-time work status significantly affects attitudes in both countries, but not the same way. It affects adversely the inclination towards a government-based pension system in the case of Japan but positively in Germany. Other significant influences are the pensioner status of the respondents in Japan and their political position in the case of German data.Livelihood of elderly, pension reform, public attitudes, aging societies, Germany, Japan

Calpains — An elaborate proteolytic system

AbstractCalpain is an intracellular Ca2+-dependent cysteine protease (EC 3.4.22.17; Clan CA, family C02). Recent expansion of sequence data across the species definitively shows that calpain has been present throughout evolution; calpains are found in almost all eukaryotes and some bacteria, but not in archaebacteria. Fifteen genes within the human genome encode a calpain-like protease domain. Interestingly, some human calpains, particularly those with non-classical domain structures, are very similar to calpain homologs identified in evolutionarily distant organisms. Three-dimensional structural analyses have helped to identify calpain's unique mechanism of activation; the calpain protease domain comprises two core domains that fuse to form a functional protease only when bound to Ca2+ via well-conserved amino acids. This finding highlights the mechanistic characteristics shared by the numerous calpain homologs, despite the fact that they have divergent domain structures. In other words, calpains function through the same mechanism but are regulated independently. This article reviews the recent progress in calpain research, focusing on those studies that have helped to elucidate its mechanism of action.

Core-tube morphology of multiwall carbon nanotubes

The present paper investigates the cross-sectional morphology of Multiwalled Carbon Nanotubes (MWNTs) restrained radially and circumferentially by an infinite surrounding elastic medium, subjected to uniform external hydrostatic pressure. In this study, a two-dimensional plane strain model is developed, assuming no variation of load and deformation along the tube axis. We find some characteristic cross-sectional shapes from the elastic buckling analysis. The effect of the surrounded elastic medium on the cross-sectional shape which occurs due to pressure buckling is focused on by the comparison with the shape for no elastic medium case in our discussion. It is suggested that in no embedded elastic medium cases, the cross-sectional shapes of inner tubes maintain circle or oval; on the other hand, an embedded medium may cause inner tube corrugation modes especially when the number of shells for MWNTs is small.Comment: 7 figures, 2 figure

Calpain chronicle—an enzyme family under multidisciplinary characterization

Calpain is an intracellular Ca2+-dependent cysteine protease (EC 3.4.22.17; Clan CA, family C02) discovered in 1964. It was also called CANP (Ca2+-activated neutral protease) as well as CASF, CDP, KAF, etc. until 1990. Calpains are found in almost all eukaryotes and a few bacteria, but not in archaebacteria. Calpains have a limited proteolytic activity, and function to transform or modulate their substrates’ structures and activities; they are therefore called, “modulator proteases.” In the human genome, 15 genes—CAPN1, CAPN2, etc.—encode a calpain-like protease domain. Their products are calpain homologs with divergent structures and various combinations of functional domains, including Ca2+-binding and microtubule-interaction domains. Genetic studies have linked calpain deficiencies to a variety of defects in many different organisms, including lethality, muscular dystrophies, gastropathy, and diabetes. This review of the study of calpains focuses especially on recent findings about their structure–function relationships. These discoveries have been greatly aided by the development of 3D structural studies and genetic models

Endoscopic treatment for cancer of the digestive tract, the development in our country, has been leading the world in particular. EMR started in 1980’s and is good procedure to remove small cancers. However, it is difficult to remove large or ulcerative lesions in single fragment. To solve these problems, ESD was developed. The author mentioned the history of endoscopic treatment and future perspectives
