The purpose of this research is to know the relationship between job satisfaction and ego-identity with psychological well-being, and it will provide a basic information for The Office workers' psychological counseling through this research. To verify it, each level of job satisfaction, ego-identity, and psychological well-being has been measured from 264 office workers in Seoul, Gyunggi, and Incheon, and correlation analysis, regression analysis using SPSS 12.0 has been done. The result of this research is as follows. First, job satisfaction had shown slightly higher correlation with positive relationship with others of psychological well-being and objective orientation of ego-identity, and all the variables of ego-identity except for initiatives had shown a static correlation with psychological well-being. Second, job satisfaction had exercised influence over Positive relation with others, self-acceptance, purpose in life and personal growth but not over autonomy and environmental mastery. Third, initiatives among the sub-ordinate variables of ego-identity had exercised a negative influence over Positive relation with others among the sub-ordinate variables of psychological well-being. Fourth, objective orientation among the sub-ordinate variables of ego-identity had exercised a static influence over job satisfaction but identity confusion had exercised a negative impact. Fifth, as a result of observing an impact job satisfaction and ego-identity had exercised over psychological well-being, it had shown a high impact in general and in particular, purpose in life among the sub-ordinate variables was valued highly. Through these results, it could be expected that job satisfaction and ego-identity would be influenced to increase their objective orientation.

Purpose: This study is descriptive correlation study to identify the factors on career identity of nursing students. Methods: From october $15^{th}$ to november 5th, 2016, data was collected through convenience sampling of 177 college students based on C province, two G provinces. Statistical analysis of t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis was performed through the SPSS WIN 21.0. Results: career identity is significantly positively related with self-esteem, and negatively related with depression (r=-.529, p<.001). Nursing students' verbal abuse is significantly positively related with sexual violence (r=.615, p<.001), depression (r=.540, p<.001) and sexual violence and depression are significantly negatively related (r=.299, p<.001) and depression and self-esteem are significantly negatively related (r=-.390, p<.001).Variables that affect career identity include depression, self-esteem, grade, and whether they belong to a specific hospital. The total explanation of career identity was 52.2%. Conclusions: These results suggest that educational intervention is needed to improve the career identity among nursing students. It is necessary to encourage students to proactively seek abuse preventive measures.

This study investigated the descriptive statistics and correlation among self-identity, school violence experience, and family social capital of adolescents and examined influence of school violence experience on self-identity and moderating effect of family social capital on the relationship between school violence experience and self-identity. Data used for analysis was from 7th grade students in The Korean Children and Youth Panel Survey in 2012. Analyses were performed using the IBM SPSS program for demographic analysis, pearson correlation, and stepwise regression analyses. Results of the study were as follows: First, the average was slightly higher for self-identity, parents' affectionate attention, and awareness of their child's friends; the average was lower for misconduct experience and victimization experience; second, there was a weak negative correlation between self-identity and bully victimization; there was a positive correlation between self-identity and family social capital (parents' affectionate attention and awareness of their child's friends). Third, to investigate the effect of school violence experience (bullying and bully victimization) on self-identity, stepwise regression analysis results were as follows: Bullying had a statistically positive influence on self-identity and bully victimization had a statistically negative influence on self-identity; both parents' affectionate attention and awareness of their child's friends had a statistically positive influence on self-identity; fourth, parents' affectionate attention had a statistically negative moderating effect on the self-identity; therefore, it signifies that the relationship between bully victimization and self-identity appears differently depending on the parents' affectionate attention, which means that the parents' affectionate attention had a negative effect on the self-identity of the adolescents who were victimized by school violence.

This study was to identify the relationship among small-medium sized hospitals nurse's career plateau, self-efficacy, job embeddedness and turnover intention. The study was conducted through a survey on 217 nurses in five small-medium sized hospitals in J city. The data were collected from August 5, 2013 to August 20, 2013. The data were analyzed by SPSS/WIN 18.0 program. The mean score of turnover intention was 3.07. The positive correlations between career plateau and turnover intention were found, but the negative correlation between self-efficacy, job embeddedness and turnover intention were found. The significant factors influencing turnover intention were job embeddedness, present clinical career, career plateau and work unit. To decrease turnover intention, therefore, nursing managers need to develop the nurse retention program for increasing job embeddedness and apply to nursing field.

In coflow jets with relatively large size nozzle and low fuel jet velocity, the buoyancy effect arises from the density difference between fuel and air streams. The present study investigated the behavior of such a buoyant cold Jet both numerically and experimentally, especially when the fuel stream has higher density than air. It has been demonstrated that the cold jet has a circular cone shape since upwardly injected fuel jet decelerates and forms a stagnation region, when the fuel jet was composed of propane highly diluted with nitrogen. When the fuel was moderately diluted, numerical results showed the Kelvin-Helmholtz type instability along the mixing layer of the jet. The stagnation height increases nonlihearly with fuel jet velocity with the power of approximately 1.64.

In combustor of SCRamjet of air-breathing engine type, the flow duration time is very short because of the supersonic air flow. In this short duration, the whole process of combustion should be done, so it is very important to study supersonic combustion technologies. In this study, we focus fuel-air mixing enhancement method using cavity and conducted 3-dimensional Navier-Stokes computational analysis. Cavity height is fixed by 10mm, length is changed from 0 to 40mm. There is a supersonic jet injection downstream of the cavity and the hole size is 1mm. As a result, the higher ratio of cavity length/height is, the higher value of vorticity gets. The increased area of vorticity expands to upper and sidewise combustor. However, the stagnation pressure loss which generates thrust loss becomes higher when the vorticity is higher. Considering these result, we can conclude that optimized design which considers the highest mixing performance and the least stagnation pressure loss is needed.

This study presents a possibility of intensification of fine dust mass concentration due to the complex urban structure using data mining technique and clustering analysis. The data mining technique showed no significant correlation between fine dust concentration and regional-use public urban data over Seoul. However, clustering analysis based on nationwide-use public data showed that building heights (floors) have a strong correlation particularly with PM₁₀. The modeling analyses using the single canopy model and the micro-atmospheric modeling program (ENVI-Met. 4) conducted that the controlled atmospheric convection in urban area leaded to the congested flow pattern depending on the building along the distribution and height. The complex structure of urban building controls convective activity resulted in stagnation condition and fine dust increase near the surface. Consequently, the residual effect through the changes in the thermal environment caused by the shape and structure of the urban buildings must be considered in the fine dust distribution. It is notable that the atmospheric congestion may be misidentified as an important implications for providing information about the residual probability of fine dust mass concentration in the complex urban area.

Lowering observers' view-height may increase the amount of occlusion across objects in a visual scene and prevent the accurate identification of the objects in the scene. Based on this possibility, memory stimuli in relation to their expected views from different heights were displayed in this study. Thereafter, visual short-term memory (VSTM) performance for the stimuli was measured. In Experiment 1, the memory stimuli were presented on a grid-background drawn according to linear perspectives, which varied across observers' three different view-heights (high, middle, and low). This allowed the participants to remember both the color and position of each memory stimulus. The results revealed that testing participants' VSTM performance for the stimuli under a different memory load of two set-sizes (3 vs. 6) demonstrated an evident drop of performance in the lowest view-height condition. In Experiment 2, the performance for six stimuli with or without the grid-background was tested. A similar pattern of performance drop in the lowest condition as in Experiment 1 was found. These results indicated that different view-heights of an observer can change the amount of occlusion across objects in the visual field, and the sensory interference driven by the occlusion may further influence VSTM performance for those objects.

The effect of lower bed height on the collapse velocity was investigated for a two-stage bubbling fluidizedbed (0.1 m in diameter, 1.2 m high) connected with a standpipe (0.025 m in diameter) for solid transport. Air was used as fluidizing gas and mixture of coarse (< $1000{\mu}m$ in diameter and $3625kg/m^3$ in apparent density) and fine (< $147{\mu}m$ in diameter and $4079kg/m^3$ in apparent density) particles as solid particles. Mixing ratio of fine particles, height of the lower bed and the distributor of the upper bed were considered as experimental variables. The collapse velocity increased with static height of the lower bed. However, the effect decreased as the mixing ratio of fine particles increased. The effect seemed to be attributed to the increase in height of the dense layer of coarse particles that prevented the gas from flowing into the standpipe, not in pressure drop for the standpipe, as the bed height increased. The collapse velocity decreased a little as the pressure drop of the distributor of the upper bed increased. An improved correlation was proposed for predicting the collapse velocity.
