This study was performed to determine the job satisfaction and its association with sociodemographic and health related characteristics, job-related factors, perception on socioeconomic status, professional job perception, job stress and social support among nursing officers. The survey was administered to 542 nursing officers working at military hospitals of the ROK Armed Forces, from Oct. 1 to Nov. 30. The structured self-administered questionnaires were delivered and they were collected without respondents' personal information. As a results, The job satisfaction of respondents turned out to be significantly higher in the following groups: an elder, married, subjective sleep quality is good, feels they are healthy, higher positional status, a longer job career, satisfied with their work, without consider quitting the job, their physical burden of work is adequate. The survey results showed that respondents' job satisfaction is positively correlated with the professional job perception and social support. while it is negatively correlated with job stress. When analyzed by Covariance Structure, it turned out that the professional job perception is more influential on job satisfaction than job stress and social support. The study found the professional job perception, high social support, and low job stress tends to improve job satisfaction. Meanwhile, the study also found that the professional job perception and high social support reduces job stress.

Recently in Korea, the policy is being proceeded to build a intergenerational housing on artificial ground of railroad site for utilizing rental house. Due to narrow space of rail road site, suitable method have to be developed such as micropiles which is known as a method of a fast construction. However, If micropile is used as foundations for the super structure, construction cost is increases compared with other pile. Consequently, new concept micropile proposed to improve both bearing capacity and cost efficiency of general micropile. New concept micropile consists of waveform cement grout surrounding tread bar that formed by grouting the soil layer with jet grouting method as control the grout pressure and flow. The micropile with waveform is expected to decrease the construction cost by cut down pile length of general micropile. This paper examined the behavior of the new concept micropile with waveform subjected to axial load using two-dimensional axisymmetric numerical analyses method. According to the numerical result, there will cost effectiveness as the pile displacement decreased despite the length of waveform micropile is down about 5% from a general micropile under the same loading condition. Also, the effect of skin friction force which mobilized from the waveform of micropile appeared at relatively soft ground.

The purpose of this research is to examine ways to improve the quality of life of elderly people living alone in urban areas by identifying their stress, social support, and quality of life as well as analyzing the relationships between these factors. In this research, a questionnaire survey was conducted for approximately two weeks including 232 elderly people aged 65 years and above who were using 10 senior welfare centers in the Seoul and Gyeonggi regions. The results of the analysis based on the collected data showed that of the stresses experienced by elderly people living alone in urban areas, the stresses of health, family, and psychological and social stresses had negative effects on social support and quality of life. Also, it was found that the social support of elderly people living alone had positive effects on the quality of life. Additionally, it was found that social support had a mediating effect in the relationship between stress and quality of life of elderly people living alone in urban areas. In other words, social support plays a buffer role in enhancing the quality of life regarding health, family, economy, and psychological and social stresses. This research has significant implications in that it was conducted on elderly people living alone, since elderly people living alone are not only under more stressful circumstances in a vulnerable environment than other seniors but also their quality of life is much lower. The implications of this research are that, from a social point of view, these elderly people living alone should no longer be neglected and that differentiated policy interventions for elderly people living alone is required.

This descriptive study aims to examine the factors that influence nursing students' adaptation to clinical practice. Data was collected from 180 nursing students between April 26 and May 4, 2018. A self-reporting questionnaire was employed, which comprised of 17 questions regarding transition shock, 24 questions about social support, two questions regarding the levels of preparedness for clinical practice, and 14 questions about the degree of adaptation to clinical practice. Collected data was analyzed using t-test, one-way analysis of variance, and stepwise multiple regression, as well as by calculating the Pearson correlation coefficient. Subjects' degree of adaptation to clinical practice had a negative correlation with their transition shock. The degree of adaptation had a positive correlation with the levels of preparedness for clinical practice (r = 0.35) and the sub-variables of social support in the domains of friends (r = 0.24), parents (r = 0.32), and professors (r = 0.38). The smaller the transition shock (B = -0.409) and the greater the levels of preparedness (B = 0.766), professorial support (B = 0.228), and parental support (B = 0.163), the higher the degree of adaptation to clinical practice. Transition shock had the greatest influence on the degree of adaptation to clinical practice felt by subjects, followed by their level of preparedness for clinical practice and professorial support. Hence, to increase the degree of adaptation to clinical practice, not only should individual nursing students be better prepared to conduct clinical practice and professors provide greater support, but also there needs to be measures implemented to reduce transition shock.

A mathematical model was proposed to analyze the vibration of diaphragm, such as the contact lenses fitted on the eyes, being subjected to the external sinusoidal pressure. The model incorporates the differential equations and their numerical solution program, based on the wave equations. Turbo-C and graphic software, formulated to describe the dependence of the various parameters involved in the vibration. The model predicts the radial distribution of amplitude, frequency dependence of both average displacement amplitude and the power of diaphragm whose edge is being either simply supported or rigidly clamped in vibration. The effect of variables such as thickness, radius, damping coefficients on the vibration characteristics was illustrated by the computer simulation of the derived program. As the frequency of driving pressure increases above the certain value determined by the boundary conditions and parameters the wave shape or pattern changes from simple arc to belly or loops having double antinode. It seems that the effect of outer antinode progressively increases as the frequency increases. If this kind of phenomena occurs to the contact lens on the cornea in vivo, it may cause an abnormal correction power in the lenses or pull off the eye due the increased rise of outer part of the lens.

The first purpose of this study is to find out whether internal support factors such as evaluation system, education support program, and human resources of universities are factors that influencing the motivation of technology transfer and commercialization among those engaged in technology transfer and commercialization activities. Second, verified the regulation effect of social support from the cause-and-effect relationship between motivation of technology transfer commercialization and the said internal factors. In order to analyze the above research, a questionnaire survey was conducted for the professors and employees engaged in the technology transfer and commercialization organization of 40 universities in Korea. A total of 160 surveys were distributed, of which 145 were collected. The results of analysis using SPSS Statistics 22.0 are as follows. First, all internal factors of university such as evaluation system, education support program, and human resources have significant influence on the motivation for technology transfer and commercialization. Second, as a result of analyzing the regulation effect of the social support in relation to the internal factor of the university and the motivation of technology transfer and commercialization, the quasi regulation effect can be founded in between evaluation system and motivation of technology transfer and commercialization. However, there is no regulation effect of social support between the education support program, human resources and motivation for technology transfer and commercialization. Based on the results of this study, suggestions can be founded for establishing a support policy for those who are engaged in technology transfer and commercialization in universities.

The purpose of this study was to examine the factors associated with adolescents' attitude toward volunteer activities. Analyses of data provided by 450 adolescents attending secondary schools in Gyeongnam Province suggested the following results. First, adolescents' attitude toward volunteer activities differed by gender, religion, and academic grades. Adolescents who were girls, who had religions, and whose academic grades were higher showed higher levels of positive attitude toward volunteer activities than their counterparts who were boys, who did not have religion and whose academic standing was lower. Second, adolescents' attitude toward volunteer activities significantly differed by the family factor. To be specific, parental attention, parental support and family's participation in volunteer work made differences to the adolescents' attitude toward volunteer activities. Third, the adolescents took significantly different attitudes toward voluntary activities according to the school factor. Significant differences were found according to attention and support from teachers. The students whose teachers had more interest in voluntary service and whose teachers offered more aid took a more positive attitude to voluntary service. Forth, some of the personal, family, and school factors were associated with adolescents' attitude toward volunteer activities. Among the personal factors, gender, religion, academic standing, and morality were associated with dolescents' attitude toward volunteer activities. Those who were girls, who were religious, whose academic standing was higher, and who were more moral took a more positive attitude toward volunteer activities. Among family and school factors, parental attention/support and attention and support from teachers affected the voluntary service attitude of the adolescents. The students whose parents had more interest and gave more support and whose teachers showed more interest and offered more support took a more positive attitude toward volunteer activities. Therefore parental attention and support were identified as the variable to make the best prediction of the adolescents' positive attitude toward volunteer activities.

The present study has extended OpenSees, which is an open-source software framework DOS program for developing applications to idealize geotechnical and structural problems, for the static analysis of axial load capacity and settlement of single piles in MS Windows environment. The Windows version of OpenSees as improved by this study has enhanced the DOS version from a general purpose software program to a special purpose program for driven and bored pile analysis with additional features of pre-processing and post-processing and a user friendly graphical interface. The method used in the load capacity analysis is the numerical methods based on load transfer functions combined with finite elements. The use of empirical nonlinear T-z and Q-z load transfer curves to model soil-pile interaction in skin friction and end bearing, respectively, has been shown to capture the nonlinear soil-pile response under settlement due to load. Validation studies have shown the static load capacity and settlement predictions implemented in this study are in fair agreement with reference data from the static loading tests.

This paper is to investigate the reinforcing effects of newly devised Tire-cell mat made of waste tires in sand. Parametric study on number of connection bolts between Tirecells, relative density of sand, embedded depth, number of reinforced layers and width of Tirecell mat was made by using plate loading tests. It is found that the number of connection bolt was enough to maintain the given pressure. The bearing capacity ratio(BCR), which is defined as the rate of ultimate bearing capacity of reinforced soil to that of unreinforced soil, is the highest at the lowest density. And the reinforcing effect can be obtained in case of embedded depth within 1.0B, where B is loading width. Also settlement reduction is the highest at the lowest density of sand. The effect of number of Tirecell reinforced layers with 0.4B to 0.5B interval is limited to 2 layers and further reinforcing effects can not be obtained beyond 3 layers. Especially, the bearing capacity increased remarkably at 1 layer of reinforcement and the degree of increase was small from 1 layer to 2 layers of reinforcement. The effect of mat width of Tirecell was not significant because of high stiffness of Tirecell although the maximum bearing capacity was shown at the 2.0B mat width and the reinforcing effects of Tirecell, in general, was prominent compared with those of commercial Geoweb.

The purpose of this study is to investigate the structural relationship among job stress, ego-resilience, social support, and burnout of art therapists. This study verified the relationship and the effect by setting a research model with job stress as independent variable, ego-resilience as mediator variable, social support as control variable, and burnout as dependent variable based on the previous studies. In order to do this study, 300 questionnaires were distributed to art therapists and the 233 questionnaires were used finally for empirical analysis. The results of this study are as follows. First, only career showed significant correlation among personal environmental factors (education, career, treatment time, income per hour, number of supervision). Second, the relationship between job stress and burnout was partially mediated by ego-resilience. Third, social support showed a regulation effect on the relationship between ego-resilience and burnout. Thus, ego-resilience showed a mediation effect in the path that job stress affects burnout, and this mediation effect varies with the level of social support. So the moderated mediation effect was confirmed.
