In this analysis frequency test, t-test, ANOVA, hierarchical multiple regression and structural equation model were used. The main findings of this study are as follows. 1. Factors which influence organizational conflict were analyzed. The type of occupation and the year of service were socio-demographic variables which influenced organizational conflict positively. Adjusted R square was 0.03. Perceptions on organizational structure and organizational culture were analyzed with two- level variables that were added. The findings were as follows. Adjusted R square increased to 0.25. The year of service, internal process culture and rational goal culture were positive variables. The design of organizational structure, human relations culture and open system culture were negative variables. 2. Variables which influence organizational commitment were analyzed. Age and the year of service were positive variables, while academic background based on high school education was a negative variable. Adjusted R square was 0.16. Perceptions on organizational structure and organizational culture were analyzed with two-level variables that were added. The findings were as follows. The characteristics of organizational structure, human relations culture and organizational culture were positive variables. Adjusted R square increased to 0.55. The variables of organizational conflict were added in 3 steps. Findings were as follows. The variables of hierarchical conflict showed negative influence and were included in two-level influential variables. Adjusted R square increased to 0.56. 3. Structural equation model was analyzed in order to examine the relation between organizational structure and the variables of organizational culture, organizational conflict and organizational commitment. Thirteen path coefficients out of seventeen path coefficients were significant. Age had negative influence on organizational conflict and positive influence on organizational commitment. The year of service had positive influence on organizational conflict and organizational commitment. The design of organizational structure, human relations culture and open system culture had negative influence on organizational. conflict. They had positive influence on organizational commitment. Internal process culture and rational goal culture had positive influence on organizational conflict. Organizational conflict had negative influence on organizational commitment. The squared multiple correlation of this model was 25.1% in organizational conflict and 52.7% in organizational commitment. The conclusion of this study is as follows. Factors in organizational structure and organizational culture, rather than socio-demographic factors, had a stronger influence on the organizational conflict and organizational commitment of hospitals. In order to decrease organizational conflict, to increase organizational commitment and to maximize the effectiveness of hospital management, it is necessary to understand the overall relation between organizational structure, organizational culture, organizational conflict and organizational commitment, with the effort of improving personalized factors and individual factors of organization management.

The purpose of this study is to investigate the factors and effects of job stress of construction workers on construction accidents and turnover intention in order to improve the field work environment of construction industry which shows higher industrial accidents than other industries. To this end, research models and hypotheses were established based on previous research, and the questionnaire was distributed to 10 construction companies in Daejeon, Sejong, and Chungcheong provinces. The 301 data collected were performed statistical analysis such as basic statistical analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, and logistic regression analysis using the statistical package (IBM SPSS 22). The results of this study are summarized as follows. First, job stress has a significant effect on accident occurrence. Among the sub-factors of job stress, there was positive (+) influence on work culture and relationship conflict between peers, and organizational system had negative influence. Job demands, compensation incompetence, and job instability were not statistically significant. Therefore, it is necessary to concentrate on the factors of work culture, organizational system, and relationship conflict in the construction site. Second, job stress has positive effect on turnover intention. Job stress, inadequacy of compensation, and work culture were positively related to turnover intention. Third, job demands have a slightly greater impact than compensatory inadequacies. The factors that make the job turnover more important are the excessive job burdens such as respect, internal motivation, responsibility rather than expectation non-conformity, time pressure, increase of work load. Therefore, in order to reduce the turnover intention of the construction worker, it is necessary to pay attention to improvement of the job requirement. Fourth, the worker's job stress could overcome by exercise and fatigue elimination, work environment management, and self-opening for others. It is necessary to establish a work environment management system for counseling and intimacy formation to open up the exercise and fatigue relief program of the workers at the construction site and to open themselves between the workers and the supervisors.

Highly open porous polymer matrices are required for high density cell seeding, efficient nutrient, and oxygen supply to the cells cultured in the three dimensional matrices. However, there are severe problems of mass transfer limitations within the cell/scaffolds culture system. Thus we hypothesize that continuos-flow culture conditioning of cells with the scaffolds may improve the cell viability and the differentiated function. In this study, we fabricated porous PLGA scaffolds by using gas-foaming/salt-leaching method as previous described. Viscous PLGA gel paste contains ammonium bicarbonate particulates, acting as a gas-foaming agent as well as a salt-leaching porogen, were cast into Teflon mold and dried. Ammonium bicarbonate salt upon contact to an acidic aqueous solution evloves gaseous ammonia and carbon dioxide by itself. And we conjugated galactose moiety [AGA; $N-(aminobuty1)-O-{\beta}-D-galactopyranosyl-(1{\rightarrow}4)-D-glucoamide]$ to the terminal end group of a PLGA to increase the cell adhesion and matain the differentiated function of hepatocytes. Cell-seeded scaffolds were secured in a flow bioreactor chamber and exposed to continuous flow at 5 ml/min. As a result of our study, the high yield of hepatocytes attachment was accomplished by increasing the concentration of PLGA-AGA conjugate in polymer scaffolds and cells in the scaffolds under continuos flow condition maintained a high level of viability and albumin secretion rate of cultured hepatocytes showed a higher level that of control groups.

It is possible to explain the design, the meaning, and the use of domestic space by comparing different cultures. The characteristics of Koreans' housing life living in western cultures has already been studied extensively. Because of political reasons, however, the characteristics of Koreans' housing life living in Chinese culture has hardly been studied at all. The purpose of this study was to find out the characteristics of succession and transformation of domestic housing culture. The data was collected by questionnaire methods from fifty Korean households and eleven Chinese households. Individual interviews and actual surveys, including taking pictures were also used for data collection. The results of this study were as follows (1)An analysis of heating system usage behaviors showed the importance of heated floors, known as Ondol, is one of the enduring characteristics of domestic habits. (2)In the sitting style, the traditional sitting on the floor was shown in living room. (3)Regarding room usage behavior, Korean households were centered around the living room in chinese houses. (4)An analysis of space organization preferences with respect to common spaces revealed that Korean households tend to prefer the open plan of common spaces.

Purpose: The purpose of this study was to identify factors influencing fall-prevention behaviors of nurses working in long-term care hospitals. Methods: Participants included 147 nurses working in 10 long-term care hospitals in B city. Data were collected from September 20-October 12, 2016. SPSS/WIN 21.0 was used for analysis with t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple regression. Results: It was found that attitude toward fall (r=.29, p<.001) and patient safety culture (r=.25, p=.002) had a significant positive correlation with fall-prevention behaviors of nurses working in long-term care hospitals. The factors influencing fall-prevention behaviors in participants were clinical career and patient safety culture (β=.21, p=.012), contributing to 19% of the total variance in fall- prevention behaviors. Conclusion: The findings showed that systematic delivery of differentiated fall prevention education is preferred to nurse's clinical career as a private factor to improve fall-prevention behaviors of nurses in long term care hospital. Particularly, it is imperative to conduct periodical and practical fall-prevention education for nurses to prevent career discontinuity. An independent report system and open communication system as well as a scheme that can disseminate patient safety culture in individual departments to implement patient direct nursing are required to encourage patient safety culture in organizations.

The purpose of this study was to examine the relationship between failure mindset of the mother and adolescent, along with the mediating effects of mother's happiness and mother-adolescents (first and second-year middle school students in Seoul) open communication. For this study, self-reported data of 270 mother-adolescent dyads were analyzed using SPSS and Process macro Model 6. The results revealed that the mother's failure mindset directly predicted their adolescent's failure mindset. The mediating effect of the mother-adolescent open communication was significant, but the mediating effect of the mother's happiness was not significant. However, the mediation effect of the mother's failure mindset on the adolescent's failure mindset through mother's happiness and mother-adolescent open communication was significant. These results suggest that "failure-is-enhancing" mindset of mothers improve their positive affect and parenting skills, which contributes to developing adolescent's belief system about failure. Putting the results together, this study is significant in that it identified the intergenerational relationship of the failure mindset. Besides, the study results serve as a foundation for intervening on the adolescent's failure mindset by verifying the developmental mechanism of the failure mindset.
