Bacteria used in self-healing concrete, which arrest the crack, helps increasing the durability is well known. However, the survival and activity of the bacteria are precisely unknown. In this research, to know the bacteria's survival curve on the surface of the cement composite, bacteria's survival curve has been measured by CFU at different curing days. The survival curve of 3 days and 7 days curing does not show the significant differences in their survival tendency. However, the slope of death phase of 7 days curing was steeper than the 3 days of curing. This research was focused on the death phase but for further research, set of interval time will be reduced and observe the lag phase and exponential phase.

Objectives：This study was to investigate the impact of parental psychiatric disorder on offspring's depression, anxiety, self concept, perception of familial relationship compared with offspring of normal control. In offsprings of parents with psychiatric disorder, this study explored whether their psychopathology, self concept, and perception of familial relationship were influenced by parent’s sex, onset time of parent’s psychiatric disorder and parent’s psychiatric diagnosis. Methods：52 offsprings aged 10-18 years of 39 psychiatric outpatient were surveyed from June, 1997 to April, 1998 and completed several questionnaaire, including Korean from of the Family Environment Scale, Korean form of the State-Trait Anxiety Inventory for Children, Korean form of Kovac’s Children’s Depression Inventory, and Korean form of Piers-Harris Children’s Self-Concept Scale. Their score was compared with offsprings’ of normals. In offsprings of parents with psychiatric disorder, they were compared according to parent’s sex, onset time of parent's psychiatric disorder and parent’s psychiatric diagnosis. Results：The results were as follows：1) Offsprings of parents with psychiatric disorder reported higher level of state anxiety and lower level of the FES expressive subscale than offsprings of normals(p<0.05). But they reported higher level of PHCSCS intellectual & school status subscale and popularity subscale than normals(p<0.05). 2) There were no differences in anxiety, depression, self concept, and perception of familial relationship between patient’s sex. 3) Offsprings less than 3 years old when parent’s psychiatric disorder had developed showed higher level of trait anxiety and lower level of FES control subscale than offsprings more than 3 years old (p<0.05). 4) There were no diferences in anxiety, depression, self concept, and perception of familial relationship between patient’ diagnostic groups(schizophrenia spectrum disorder-mood disoderneurosis). Conclusion：The finding indicated that self reported scale of anxiety and depression showed no significant difference between offsprings of psychiatric patients and offsprings of normals. In offsprings of parents with psychiatric disorder, parent’s sex and psychiatiric diagnosis had no influence on offspring’s psychopathology. But the offspring’s age(before 3 years old) when the parent’s psychiatriric disorder developed had influence on higher level of offspring’s trait anxiety. For further high risk group study, direct interview and evaluation of parent-child agreement or teacher-child agreement will be needed in longitudinal study.

Instagram, a photo and image centered social networking service, has received increasing attention these days, from scholars and practitioners. However, little is known about the social and psychological factors that lead consumers to use this service. To provide a baseline understanding on Instagram users, the current study was conducted to discover perfectionistic self-presentation tendency expressed by the Instagram users and explore the relationships between identified perfectionistic self-presentation and intention to use Instagram variables with 250 participants. In addition, this study tried to determine the moderator effect of self-efficacy and self-construal. A comprehensive survey was directed and a total of 380 participants were recruited to verify anticipated hypotheses and research questions. The research results suggest that perfectionistic self-presentation has five sub factors: others conscious self-presentation, subjective self-presentation, environmental adaptation self-presentation, self-expansion self-presentation, and social self-presentation. The implications of this research findings are discussed.

The purpose of this study was to investigate the relationship between self-management, stress coping, and physical self-concept of health exercise participants. To this end, a total of 274 questionnaire results were obtained by visiting 12 fitness center in the metropolitan area that is running a health exercise program. This was analyzed through the SPSS program, and the following results were obtained. It showed a significant explanatory power in the relationship between self-management and stress coping of health exercise participants. In addition, it also showed significant explanatory power in the relationship between self-management and physical self-concept. Finally, it showed significant explanatory power in the relationship between stress coping and physical self-concept. Through this study, it was found that there was a significant causal relationship between self-management, stress coping, and physical self-concept of healthy exercise participants. In follow-up studies, an in-depth analysis of self-management is required through the causal relationship with environmental factors related to self-management.

This paper is to technically implement the sensing platform for Home-Wellness Robot. First, self-localization technique is based on a smart home and object in a home environment, and IOT(Internet of Thing) between Home Wellness Robots. RF tag is set in a smart home and the absolute coordinate information is acquired by a object included RF reader. Then bluetooth communication between object and home wellness robot provides the absolute coordinate information to home wellness robot. After that, the relative coordinate of home wellness robot is found and self-localization through a stereo camera in a home wellness robot. Second, this paper proposed fuzzy control methode based on a vision sensor for approach object of home wellness robot. Based on a stereo camera equipped with face of home wellness robot, depth information to the object is extracted. Then figure out the angle difference between the object and home wellness robot by calculating a warped angle based on the center of the image. The obtained information is written Look-Up table and makes the attitude control for approaching object. Through the experimental with home wellness robot and the smart home environment, confirm performance about the proposed self-localization and posture control method respectively.

This study aimed to examine the hypothesis that intrapersonal, interpersonal, and environmental self-awareness would alleviate the association between sSchadenfreude and cyberbullying. 300 middle and high school students answered survey questionnaires including sSchadenfreude, cyberbullying behavior, (intrapersonal. interpersonal, and environmental) self-awareness, depression, and anxiety. After controlling depression and anxiety, theThe results reveal that first, Schadenfreude predicts cyberbullying behavior, so those who have a high level of Schadenfreude commit more online cyberbullying behavior. Second, intrapersonal and interpersonal self-awareness moderated the association between schadenfreude and cyberbullying, and those who were above average on intrapersonal and interpersonal self-awareness were more liable to commit cyberbullying, but those below average did not show a significant moderation effect. Third, whereas environmental self-awareness did not show a significant moderation effect. Specifically, those who know well what they think and do and what they look like in interpersonal relationships perpetrate more cyberbullying when their schadenfreude was high. However, knowing well about what was happening around them was not related to the likelihood of schadenfreude that lead to cyberbullying. The results of this study revealed that Schadenfreude, which deals with emotions on expecting the misfortune of others and the possibility of having antisocial characteristics, lead to actual cyberbullying behaviors of adolescents. Also, this study identified that intrapersonal and interpersonal self-awareness are harmful in causing cyberbullying in those with high Schadenfreude. Finally, the implication and the limitation of this study were discussed.
