This study was examined the impact of acculturation stress and job satisfaction on the organizational commitment among dispatched hospital-workers in UAE. Data were collected with a convenience sample of 107 from March 1 to August 30, 2016. Analysis was conducted using t-test, ANOVA, Spearman rank-order correlation coefficient and Hierarchical regression analysis. The results of the study showed that first, the lower the acculturation stress, the higher the job satisfaction and organizational commitment, and the higher the job satisfaction, the higher the organizational commitment. Second, job satisfaction was significant to predict the level of organizational commitment among dispatched hospital-workers in UAE. Therefore, it is important not only to enhance the job satisfaction but also to reduce the acculturation stress before dispatch in order to improve the organizational commitment of dispatched hospital-workers, and various programs need to be developed for such education.

An advanced aeroelastic formulation for flutter analyses is presented in this paper. Refined 1D structural models were coupled with the doublet lattice method, and the g-method was used for flutter analyses. Structural models were developed in the framework of the Carrera Unified Formulation (CUF). Higher-order 1D structural models were obtained by using Taylor-like expansions of the cross-section displacement field of the structure. The order (N) of the expansion was considered as a free parameter since it can be arbitrarily chosen as an input of the analysis. Convergence studies on the order of the structural model can be straightforwardly conducted in order to establish the proper 1D structural model for a given problem. Flutter analyses were conducted on several wing configurations and the results were compared to those from literature. Results show the enhanced capabilities of CUF 1D in dealing with the flutter analysis of typical wing structures with high accuracy and low computational costs.

$BaTiO_3$(BT) has high permittivity so that has been applied to dielectric and insulator materials in 3D system-level package integration. In order to achieve excellent performance of device, the BT layer should be highly dense. In this study, BT thick films were prepared by the inkjet printing method. And these films were cured at $280^{\circ}C$ after infiltration of polymer resin. As a result, we have successfully fabricated not only the inkjet-printed hybrid BT film but also metal-insulator-metal(MIM) capacitor without sintering process. Changes in the dielectric constant of BT hybrid film with particle size and packing density were investigated. The dielectric constant was increased with increasing packing density and particle size. Further, the BT hybrid film using two different size particles had even higher packing density and dielectric constant.

A two-dimensional higher order panel method using B-splines has been developed to overcome the disadvantages of the low order panel method and to obtain more accurate solution. The sources and the normal dipoles are distributed on both the body and the free surface. Instead of applying the upwind finite difference schemes to satisfy the linearized free surface and the radiation condition, the derivatives of the basis functions of the B-splines are directly applied to the linearized free surface condition. Numerical damping in the Dawson's method are avoided in the Present computations. In order to validate the present method, numerical computations are carried out for a submerged cylinder and a two-dimensional hydrofoil steadily moving beneath a free surface. The numerical results show that fast convergence and better accuracies have been achieved by the present method.

We report here flexible dye-sensitized solar cells (DSSC) based on Ti-mesh electrodes that show good mechanical flexibility and electrical conductivity. $TiO_2$ nanotube arrays prepared by electrochemical anodizing Ti-mesh substrate were used as photoanode. A Pt-coated Ti-mesh substrate was used as counter electrode. The photoanodes were modified by coating a $TiO_2$ porous layer onto the $TiO_2$ nanotubes in order to increase the specific surface area. To increase the long term stability of the DSSCs, a gel type electrolyte was used instead of a conventional liquid type electrolyte. The DSSC based on $33.2{\mu}m$ long porous $TiO_2$ nanotubes exhibited a better energy conversion efficiency of ~2.33%, which was higher than that of the DSSCs based on non-porous $TiO_2$ nanotubes.

Excluding unhonest data, the number of cases used for the final analysis is 337 people. The collected data were analyzed for the study purpose using SPSSWIN 18.0, as statistical techniques, factor analysis, reliability analysis, correlation analysis, t-test, one-way ANOVA, multiple regression analysis, path analysis etc. were used. First, social security network building has an effect on civil culture. That is, the more activated voluntary crime prevention activity, the higher order law-abiding spirit. The more activated local government security education, police public order service, the higher awareness of participation becomes. First, social security network building has an effect on civil culture. That is, the more activated voluntary crime prevention activity, the higher order law-abiding spirit. The more activated local government security education, police public order service, the higher awareness of participation becomes. The more activated voluntary crime prevention activity, street CCTV facilities, police public order service, the higher tolerance spirit becomes. On the contrary, street CCTV facilities reduce citizens' autonomy. Second, social security network building has an effect on community unity. The more activated street CCTV facilities, police public order service, crime prevention design, the higher a sense of stability becomes. The more activated local government security education, police public order service, crime prevention design, the higher awareness of community becomes. The more activated voluntary crime prevention activity, government security education, police public order service, crime prevention design, the higher community institution becomes. Third, civil culture has an effect on community unity. That is, the more activated awareness of community, tolerance spirit, the higher a sense of stability, awareness of community and community system become. Fourth, social security network building has an effect on civil culture and community unity. That is, social security network building has a low effect community institution directly, but if civil culture is enhanced through social security network building, then it has a high effect on community unity.

This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

This study investigated the effects of job satisfaction on job commitment and turnover factors of physical therapists working in residential facilities for the disabled. Job satisfaction (23 questions) and organizational commitment (11 questions) were investigated for 122 physical therapists working in residential facilities for the disabled. As a result of the study, the job satisfaction of physical therapists working in residential facilities for the disabled was 3.16, and the level of organizational commitment was 3.29, which was moderate. Among job satisfaction, higher self-esteem, superior and welfare system, communication, and satisfaction with colleagues showed higher organizational commitment. Self-esteem, supervisor and welfare system, communication, and co-worker factors were found to affect emotional commitment. Physical therapists working in residential facilities for the disabled pointed out dissonance between their boss and colleagues, poor working environment, salary problems, and excessive work as factors for turnover. In order to increase organizational commitment of physical therapists working in residential facilities for the disabled, it seems that respect for their work and improvement of relationships with superiors and colleagues are necessary.

The study examined the impact of medical servicescape, human services, and effects on perceived value and customer satisfaction. From July 1, 2016 to August 31, 2016, a total of 300 outpatients visiting the university hospital and general hospital in Ulsan area participated the study. As a result, the general features of the Servicescape were more important to the aged and the higher the academic background, the higher the scores of Human Service and perceived value were revealed. There was a positive correlation between the service schedule of the medical institution, human service, perceived value, and customer satisfaction. And the factors affecting customer satisfaction were in order of human service (${\beta}=0.382$), perceived value (${\beta}=0.376$). The service scapegoats and personal services offered by customers visiting healthcare providers play an important role in understanding the internal health and needs of customers, and this research results will serve as a basic material for strengthening the competitiveness of medical institutions.
