Characterizations of $\mathcal{N}$-subalgebra of type (${\in}$, ${\in}{\vee}q$) are provided. The notion of $\mathcal{N}$-subalgebras of type ($\bar{\in}$, $\bar{\in}{\vee}\bar{q}$) is introduced, and its characterizations are discussed. Conditions for an $\mathcal{N}$-subalgebra of type (${\in}$, ${\in}{\vee}q$) (resp. ($\bar{\in}$, $\bar{\in}{\vee}\bar{q}$) to be an $\mathcal{N}$-subalgebra of type (${\in}$, ${\in}$) are considered.

Let A be a $JB^*$-triple with Banach dual space $A^*$ and bi-dual the $JBW^*$-triple $A^{**}$. Elements x of $A^*$ of norm one may be regarded as normalised 'Q-measures' defined on the complete ortho-lattice ${\tilde{\mathcal{U}}}(A^{**})$ of tripotents in $A^{**}$. A Q-measure x possesses a support e(x) in ${\tilde{\mathcal{U}}}(A^{**})$ and a compact support $e_c(x)$ in the complete atomic lattice ${\tilde{\mathcal{U}}}_c(A)$ of elements of ${\tilde{\mathcal{U}}}(A^{**})$ compact relative to A. Necessary and sufficient conditions for an element v of ${\tilde{\mathcal{U}}}_c(A)$ to be a compact support tripotent $e_c(x)$ are given, one of which is related to the Q-covering numbers of v by families of elements of ${\tilde{\mathcal{U}}}_c(A)$.

This paper describes the design and implementation of library for real-time operating system Q+, that was developed for the internet appliance. The library in the real-time operating system should be defined according to the standard interface and support the functions that are adequate to the real-time application. To ensure the compatibility between application programs, the Q+ library follows industrial and international standards, such as POSIX.1, ISO 7942 GKS. And, to support the Q+ application, library provides C standard functions, graphic/window functions, network functions, security support functions, file system functions. The Q+ library was implemented using the Q+ kernel, Digital TV set-top box, and KBUG debugging tool.

Stability analysis and support system estimation of the Beheshtabad water transmission tunnel is investigated in this research. A combination approach based on the rock mass rating (RMR) and rock mass quality index (Q) is used for this purpose. In the first step, 40 datasets related to the petrological, structural, hydrological, physical, and mechanical properties of tunnel host rocks are measured in the field and laboratory. Then, RMR, Q, and height of influenced zone above the tunnel roof are computed and sorted into five general groups to analyze the tunnel stability and determine its support system. Accordingly, tunnel stand-up time, rock load, and required support system are estimated for five sorted rock groups. In addition, various empirical relations between RMR and Q i.e., linear, exponential, logarithmic, and power functions are developed using the analysis of variance (ANOVA). Based on the significance level (sig.), determination coefficient (R²) and Fisher-test (F) indices, power and logarithmic equations are proposed as the optimum relations between RMR and Q. To validate the proposed relations, their results are compared with the results of previous similar equations by using the variance account for (VAF), root mean square error (RMSE), mean absolute percentage error (MAPE) and mean absolute error (MAE) indices. Comparison results showed that the accuracy of proposed RMR-Q relations is better than the previous similar relations and their outputs are more consistent with actual data. Therefore, they can be practically utilized in designing the tunneling projects with an acceptable level of accuracy and reliability.

Purpose: This study aimed to identify on the attitudes toward the life support care among elderly people using Q methodology. Methods: Thirty-nine elderly people classified 34 selected Q statements into a shape of normal distribution using a 9 point scale. The obtained data were analyzed by using a PQ Method PC program. Results: Principal component analysis identified 4 types of the attitudes toward the life support care among elderly people. Type I is "Situational & Self-determination linear type", type II is "Destiny & Life support care denied type", type III is "Avoidant & Family decision emphasis type" and type IV is "Respect for life & life support care approved type". Most of elderly people have been attitude that wish to receive honor their own decisions toward the prolongation treatment. Conclusion: The findings indicate a need to policy guidelines and public information that express self-determination of elderly people.

This study started to examine the understanding and perception of 'disabled people' and 'non-disabled people', one of the dichotomous elements in the 21st century social integration era. In particular, for the analysis, Q-methodology, which should respond based on the respondent's inner self and perception, was used. For the analysis, 32 Q-statements were secured, and as a result of targeting 20 P-sample respondents, three types were derived as follows. In , statements such as 'A correct awareness of disability is necessary' and 'Disability can occur to anyone' are emphasized, so it was named 「Correct Perception Emphasis Type」. emphasized 'The life of the disabled is not easy' and 'The disabled need an opportunity to participate in society' and was named 「The Life of the Disabled Understanding Type」. emphasized statements such as 'Economic support is necessary for the disabled' and 'The welfare budget for the disabled must be sufficiently secured', and was named 「Institutional Support Emphasis Type」. Therefore, in addition to the necessity of correct recognition of disability and disability in our society, we expect this study result is to be priming water for improving the recognition of the disabled.

This study was undertaken to investigate the relationship between social support and depression of the elderly in care facilities. We enrolled 328 elderly people aged 65 years or older, admitted to 15 care facilities located in D metropolitan city. Data were collected through personal interviews conducted by interviewers who visited each care facility, from March 1 to May 31, 2018. Our results indicate a significantly higher distribution of depression in the group having lower social support; the score of depression was determined to be in a significant positive correlation with social support. Considering logistic regression, the adjusted odds ratio in the depressed group increased significantly by 2.7 times in the high group (Q3), 5.4 times in the middle group (Q2) and 10.1 times in the low group (Q1), which had the very high group of social support score. Multiple regression analysis revealed that the factors influencing depression include religion status, relationship with children, subjective health status, physical disabilities, smoking status, breakfast status, and social support, and the explanation power of the injected variables is 41.1%. Taken together, our findings indicate that the level of depression amongst the elderly in care facilities is significantly related to the social support available.

The purpose of this study is to find out perception types of interested group in college on the education-welfare support for disabled college students by Q-methodology, then to search for political measures to support of disabled college students in the implication of the sorted subjective viewpoints. The result of this study showed that there are four major sorts of perception types on the education-welfare support for disabled college students: requests for realistic and comprehensive services for stable college life(Type1), requests for the disabled personalized services for the vocational life after graduation(Type2), lacks of understanding on the education-welfare support and disabled college students(Type3), and ambivalences on the education-welfare support(Type4). The findings of this study are summarized as several kinds.

This research examined elderly’s quality of life(q/l). In order to explore the elderly’s q/l, it was conceptualized into 8 dimensions tapping macro and micro aspects of elderly’s life: physical & mental health, self-esteem, anxiety, social support, family solidarity, economic state, and physical environment. The primary purposes were to describe dimensions of q/l by the elderly’s sociodemographic variables. And the intercorrelations among q/l dimensions were examined and then the effects of q/l sub-dimensions on psychological well-being were analyzed by using multiple regression. Based on the data collected for 677 subjects residing in rural and urban areas, the basic issues hypothesized were explored. The findings appeared that the psychological well-being was a positive function of physical and mental health, self-esteem, social support, and economic state and a negative one of social anxiety, controlling for subjects’s sociodemographic variables.
