  • Oxidative damage resulted from reactive oxygen species (ROS) is one of the main causes for the decrease of the viability during in vitro culture and cryopreservation process. This experiment was performed to determine the effects of antioxidants on the human hematopoietic stem cell (HSC) during cryopreservation procedure. HSCs cultured in vitro with or without antioxidants were frozen and then examined for stem cell potential after thawing. The cell viability of thawed HSC was increased in $\alpha$-tocopherol and ascorbic acid treatment group compared to control group ($62.7{\pm}8.0%$) and it was higher in 150 uM $\alpha$-tocopherol treatment group ($70.5{\pm}7.0%$). No significant difference was observed in the membrane integrity in all groups. In auto-differentiation rate, no significant difference was appeared in all groups, but was lower in 150 uM $\alpha$-tocopherol ($7.3{\pm}2.6%$) compared to control group ($10.1{\pm}1.6%$). These results demonstrate that treatment of antioxidants improves the efficiency of cryopreservation for HSC and $\alpha$-tocopherol may be considered effective antioxidant for the protective effect on HSC.

  • Previous resarch demonstrated that moral judgment is not an outcome of rational reasoning, but an independent variable determined by diverse factors. The effects of disgust on moral harshness, audience effect on moralistic punishment are some examples that support this view. The variability of moral judgment raises a question on what effects video stimuli might have on moral judgments. Although a few studies (Schnall, Roper, & Fessler, 2010) have shown that watching a prosocial video clip promote moral behavior, no research have simultaneously tested the effects of both positive and negative video clips on moral (not bahavior but) judgments. Hence, this research tested the effects of viewing videos about good and evil on moral judgments regarding the self and others. To this end, participants were asked to view a video clip depicting content of either positive or negative human behavior and required to make moral judgments on conduct described in a scenario assuming that the person committing the act was either themselves or another person. The results showed significant effects of both video contents (positive, negative) and the actor (self, others) on moral judgments, but they were qualified by the interaction between the two. In particular, participants who watched evil deed of others made harsher judgments on others' moral transgression. Theses results demonstrate that video contents influence moral judgments, and the effect depends on the actor of the immoral behavior. In general discussion, we interpreted the results based on moral disgust, framing effect, and fundamental attribution error.

  • Desire for a happy life becomes the will that man instinctively desires. In that the conditions of happiness are subjective and varied, the will of subjective desires has been studied with the attention of objective tendencies. The positive and meaningful will of life in the desire for happiness leads us to be the functionaries who act. These wills can be the driving force of a happy life, which allows one to have a hopeful reflective will in one's inner life, connecting oneself with others, and working in relationships with others. In addition, those who become lazy or lose their orientation in life can instill a will to be the main character of life, and furthermore, to give the ultimate meaning and goals of life. To understand and analyze these wills for happy lives more specifically, structural model compatibility and confirmatory factors were conducted. relatively reliable α=.855 value, the coefficient of correlation between recognition and will **p<.01, *p<.05 statistically significant measuring tool of not less than 05 was used. The study results of the structural model suitability of the factors of will and the confirmatory factor analysis showed that the model set by the researcher could reflect the characteristics of the data collected, and that the χ2(Chi-square) value was .126, which was consistent with the model by satisfying the acceptance criteria, and that the comparison of the reference values of the study model showed a relatively high level of suitability. To identify the relationship between cognitive and defined and behavioral factors of subjective will and existent will variables, the results of a verification factor analysis show that the χ2(Chi-square) value is 2.36 and the model and data are consistent with the acceptance criteria, and that the test data is consistent with the model and data set by the researcher are consistent with the model5.0 Through structural model analysis of human will, it was confirmed that the variables of subjective and existential, sensible and reflective will directly and indirectly influence and form a complex relationship. Our will is recognized as the subjective will, and the structure of the subjective will consists of the sensible and reflective will, and the relationship between the cognitive and just action elements and the subjective will of the human life and the will to exist is shown to be very meaningful, so we should conduct the education of the happy will of the emotional and just areas of life as well as the reestablishment of the cognitive educational direction that can lead to action.

  • The aim of this study is to structuralize a model of the factors determining the quality of nursing care perceived by the director or manager of a long-term care facilities (hospitalization of patients) using FSM(Fuzzy Structural Modeling), employed in structuralizing social systems. The results were as follows: first, quality in the top tier was shown to be connected with job commitment, commitment to the organization, work experience, care skills, knowledge about the elderly, training and education, which are factors in the middle tier; and second, the structure of the middle tier (job commitment, commitment to the organization, work experience, care skills, knowledge about the elderly, training and education) either showed a connection with the lower tier, which includes employment type, job satisfaction, leadership, relationship with users and workplace relationships, or showed a connection among the factors within. These results confirmed the following: first, care skills and knowledge about the elderly, which demonstrate the job expertise of caregivers, showed a connection with service quality based on work experience; second, job commitment in the middle tier was observed to affect various factors in the same tier such as care skills, knowledge about the elderly, training and education amongst others, and it was determined that it is an important determining factor in service quality. Lastly, a meaningful result was shown in relation to leadership. The leadership skills of the director of the facilities had a connection with the care caregivers' commitment to the organization, which had a connection with service quality. This structure showed the kind of role the director must play in order to improve service quality.

  • This study has analyzed the factors related to everyday stress, professional stress, and professional satisfaction experienced while performing administrative duties in unit of school, concerning administrative education government officials. The study period was set from March 10 to March 30, 2013, and the subjects of study was set as 122 employees of Cheongwon-gun, Cheongju-si, Chungcheongbuk-do, working as administrative education government officials. The spsswin18.0 program was used for data analysis, and the t-test, and frequency analysis and credibility were also analyzed. The positive analysis was verified at a significant level of 5%. The results of the analysis displayed regarding the Professional Satisfaction pursuant to demographic Characteristic, the difference of Professional Satisfaction between positions was meaningful. However, the differences between sex, age, religion, educational background, marital status, school level, school scale, career, drinking, smoking were not analyzed as meaningful at a significant level of 5%. With regard to Sub-factors of Professional Satisfaction for Demographic Characteristic, the factors in the part of human resource management, human relation, and job capacity were analyzed as meaningful but organizational atmosphere was analyzed as not meaningful at a significant level of 5%. Also with regard to the stress on Quantitative Role among Sub-factors of Professional Stress by Demographic Characteristic, the difference between age, school level, position, career, smoking was meaningful. With regard to career development, the difference between smoking was meaningful. With regard to the stress on role conflict and ambiguity, the difference for demographic characteristic was analyzed as not meaningful at a significant level of 5%. This study implies that the social environmental consideration is required for administrative education government officials, and it is regarded that consideration is required sequentially to developing job capacity, human relation, organizational atmosphere, rather than to human resource management.

  • A systemic approach to behavior on the basis of human psychology is needed for behavior-centered space design. Also, the recognition that human and environment, in all, have complementarity is needed- human and space shall be understood as a general phenomenon, supposing interaction. Design of behavior-oriented space means configuration and coordination of physical subjects as well as understanding, analysis and reflection of psychological and behavioral phenomena. It is analysis of a private individual as well as understanding of interaction between human groups, as well. In respect of space recognition, analysis not on material movement but on energy circulation and variable is important. It means that the understanding of user's behavior and psychology does not orient reasonable purpose just for convenience. That is, such understanding intends to understand behavioral patterns and psychological phenomena between space and human beyond the decomposition of structure of human and space into physical elements and the design based on standardized data. Thereby, more human-oriented space design might be implemented by the understanding of behavioral essence. Also, a user-centered design process from another viewpoint might be created, and the general amenity among man, space and environment - better environmental quality - might be produced. For this, the consciousness of human activity that is, activity system shall be ahead of it, and the approaches for design shall be implemented into a process not in predictive ideas but in semi-scientific system. On the basis of the above view, this study was attempted to investigate the orientation of design to recognize space as another life, and explore a process where it is drawn into a design language on the basis of human behavior. If the essence of space behavior and the activity system are analyzed through user observation and it is reflected upon a space design program and then developed into a formative language, a new design process on human and environment might be produced. In conclusion, the reflection of user's behavior and psychology into design, contrary to existing public space design based on physical data, can orient quality improvement of human life and ultimately be helpful to the proposition, 'humanization of space'.

  • This study is intended to look into the effects of project leader's core competencies(intellectual ability, management ability, emotional ability) on the Critical success factors(job satisfaction, organizational commitment, group cohesion) of project by environmental variables of organization. The results of this study were summarized as follows. First, the intellectual ability, management ability and emotional ability had a significant effect on the job satisfaction, organizational commitment and group cohesion. Second, the functional organization and project organization had a partial effect on project leader's core competencies. But the individual-centered organization had no moderating effect. For the project organization, all intellectual ability, management ability and emotional ability had a moderating effect on the organizational commitment. Consequently, project leader's core competencies are mechanisms to improve the job satisfaction, organizational commitment and group cohesion, and they have a different moderating effect according to the type of organization.
