This paper presents the details of size independent fracture energy and bi-linear tension softening relation for nano modified high strength concrete. Nano silica in powder form has been used as partial replacement of cement by 2 wt%. Two popular methods, namely, simplified boundary effect method of Karihaloo et al. (2003) and RILEM (1985) fracture energy with P-${\delta}$ tail correction have been employed for estimation of size independent fracture energy for nano modified high strength concrete (compressive strength ranges from 55 MPa to 72 MPa). It is found that both the methods gave nearly same values, which is an additional evidence that either of them can be employed for determination of size independent fracture energy. Bi-linear tension softening relation corresponding to their size independent fracture energy has been constructed in an inverse manner based on the concept of non-linear hinge from the load-crack mouth opening plots of notched three-point bend beams.

This study aimed to examine the relationship between the expectation of independent life in old age and intergenerational downward transfer of Korean old people. It was focused on old people who did not live with their adult children by using the raw data of "2008 the Korean study of Welfare Services for the Elderly". The data were analysed by multiple regression analysis. The results showed the degree of the expectation of independent life in old age had positive effect on economic and service downward transfer of old people. Concretely, the degree of the expectation of economic and physical independence had positive effect on economic and service downward transfer of old people. The degree of the expectation of emotional independence had positive effect on service downward transfer of old people, while it had no effect on economic downward transfer.

This study purports to investigate the determinants of patient satisfaction and intent to revisit at national university hospitals in Korea. A total of 8 independent variables for outpatients, 9 independent variables for inpatients, and an intervening variable of overall patient satisfaction were selected through literature review. The independent variables for outpatients contain the level of satisfaction with physicians, nurses, ancillary staff, administrative procedure, medical cost, physical environment, facility convenience. and health recovery. With regard to the independent variables for inpatients, the quality of ward services was added to those of outpatients. Each variable contains 3 to 8 items measuring the level of satisfaction with various aspects of the variable. The sample used in this study consisted of 879 outpatients and 821 inpatients. Data were collected with interview survey and analyzed using path analysis. The major findings of the study are as follows: 1) The following variables have significantly positive effect on the intent to revisit of outpatients: health recovery, overall satisfaction, satisfaction with physicians, and ancillary staff. 2) The following variables have significantly positive effect on the intent to revisit of inpatients: health recovery, satisfaction with nurses and physicians, overall satisfaction, and administrative procedure. 3) The following variables of admission procedure, satisfaction with ancillary staff, facility convenience, quality of ward services were found to have significantly positive effect only on the level of overall satisfaction, even though they do not have significant total effect on the intent to revisit. The results of the study indicate that national university hospitals in Korea should make an effort to improve the satisfactory level of patients with clinical outcome, services provided by physicians, nurses, and ancillary staff, and the quality of administrative procedure for enhancing the intent to revisit of patients.

Two apparent rho-independent transcription terminator structures within the coding sequence of aceK have been destroyed to access their roles in the differential expression between aceA and aceK in the glyoxylate bypass operon of E. coli. The effect of mutations on the expression of aceK was evaluated in two different ways: one by maxicell labeling and the other by lacZ fusion gene construction. The maxicell labeling experiment with the mutant operon clones has failed, like that of the wild type operon clone, to visibly show isocitrate dehrogenase (IDH) kinase/phosphatase, the product of aceK, on the autoradiogram of a protein gel. When the same mutations were introduced into an aceK::lacZ fusion gene to quantitatively evaluate the mutational effect, the activity of ${\beta}-galactosidase$ in neither of the mutant versions of the fusion gene was elevated significantly enough to explain the degree of polarity observed in this region. Thus, we conclude that neither of these intragenic, apparent rho-independent transcription terminator structures, which have long been suspected as a major determinant in the down regulation of aceK, really act as a premature transcriptional terminator.

The purpose of this study is to examine the effect of psychosocial rehabilitation services on the independent living of the mentally ill people. The study was conducted using mentally ill people who were using services offered by psychosocial rehabilitation service center during the study period, have lived independently, and used the service center for three months or longer. The data analysis included 231 surveys collected from 42 agencies and then perform hierarchical regression analysis. As a study result, the number of types of psychosocial rehabilitation service used by the mentally ill people and the greater the satisfaction with the psychosocial rehabilitation service, the more independent living competency of the mentally ill people was received. This means that community-based integrated psychosocial rehabilitation service have the effect of contributing to strengthening the competency of independent living with the mentally ill people. Based on the research results, this study proposed the development of integrated mental rehabilitation service to improve the independence competency of the mentally ill people.

This study empirically analyzed the factors affecting the intention to utilize manufacturing AI in SM-sized manufacturers by applying the TOE framework. Independent variables that are expected to influence were applied, focusing on TOE factors and managerial characteristics that reflect the characteristics of SME manufacturers. In addition, the mediating effect of technology trust and the moderating effect of factory location were analyzed. The results are as follows. First, the relationship between the independent variables and the dependent variable was tested, and the direct effects of the independent variables(complexity, organizational innovation, IT ability, competitive pressure, partner support, and managerial innovation) on the dependent variable were all statistically significant, except for compatibility. Second, the mediation effect of technology trustness was verified to have a full mediation effect between compatibility and utilization intention, and a partial mediation effect between managerial innovation and utilization intention. Third, among the seven independent variables, the moderating effect of factory location(metropolitan and non-metro) between the three independent variables of IT ability, competitive pressure, and partner support and the utilization intention was found to be significant. To increase the intention to utilize manufacturing AI for SM-sized manufacturers, it is recommended that more diverse and broader studies are needed, not only the factors identified in this study, but also the understanding and awareness of manufacturing AI.

An independent kinematic hardening material model in which the reverse yielding point is defined by the Bauschinger effect factor (BEF) , has been defined for stainless steel SUS 304. The material model and the BEF are obtained experimentally and represented mathematically as continuous functions of effective plastic strain. The material model has been incorporated in a non-linear stress analysis for the prediction of reverse yielding in thick-walled cylinders during the autofrettage process of these vessels. Residual stress distributions of the independent kinematic hardening material model at the onset of reverse yielding are compared with residual stresses of an isotropic hardening model showing the significant effect of the BEF on reverse yielding predictions. Critical pressures of direct and reverse yielding are obtained for the most commonly used cylinders and a range of permissible internal pressures for an efficient autofrettaged process is recommended.

This research aimed to verify whether family competency reinforcement had a mediating role on the effect of family cohesion of the Down syndrome family upon the independent life of children with Down syndrome. For the research, 146 families belonged to Down Syndrome Parent Assembly were surveyed and the statistical program SPSS WIN 25.0 was utilized for the data analysis. To verify the mediating effect, Baron and Kenny's causal step strategy was performed. As a result of the study, the higher the family cohesion of the Down syndrome family was, the greater the level of independence of the child was, indicating that the family cohesion had a significant static effect on the independence life. In addition, it was confirmed that the family competency reinforcement played a mediating role between the family cohesion and the children's independent living. Therefore, the results of this research suggested that it might be used as a policy approach and supporting plan for the realization of support for independence of Down syndrome children.
