This study investigated the significant difference in the influences of pregnant couples' attachment representation for parents of origin on their psychological symptoms according to groups. One hundred and eighty two pregnant couples answered the questionnaire. Data were analyzed by means of frequency, percentages, t-test. Pearson's correlation using SPSS ver. 21.0 and multiple group structural equation modeling using AMOS ver. 20.0. The findings are as follows. First, there were significant differences in attachment representations according to parents of origin and psychological symptoms between pregnant women and spouses. Second, there were negative influences of attachment representations to parents of origin on psychological symptoms for both the pregnant women group and their spouses group, respectively. Last, the negative effects of attachment representation for parents of origin on their psychological symptoms according to groups were significantly different; consequently, the impact on the spouses group was stronger than the pregnant women group. The results imply that policies to help pregnant couples reduce psychological symptoms should be provided. In addition, the unexpected result on the weaker impact of pregnant women's attachment representation for parents of origin on their psychological symptoms suggests it is better to consider other factors simultaneously (such as a romantic attachment to spouses) that might provide a moderating role. The study results are meaningful because it is the first to apply a statistically advanced method to analyze pregnant women and spouses in relation to parents of origin on their psychological symptoms.

The purpose of this study was to find and provide the prevention method by examining the Effects of Maternal Negative Behaviors and Children's Attachment Stability on Children's Aggression. The subjects were 339 children of fifth or sixth graders in Seoul. The questionnaires were derived and modified from Young Ae Park (1995) for the maternal negative behavior, Children's attachment stability from Ok Jung (1998) and Children's aggression from In Sun Jung(2006). The date were analyzed with descriptive statistics, t-test, F-test, Pearson's correlations and hierarchical multiple regression by SPSS 14.0 program. The major findings were as follows : First, the result showed there was average level of negative relationship when mother's negative behavior was compared with children's attachment whereas it showed average level of positive relationship in aggression. And also, low level of negative relationship showed between the attachment and aggression. Second, studying the influence it gives to the children's reaction and aggression after adding the children, parent and the family's popular social variables into the maternal's negative behavior, the outcomes showed the maternal's discipline and defiance upbringing had influenced the highest and tolerance, negligence was second high. This study mainly looked at the relationship between the maternal negative behavior with the children's attachment and aggression, but not like the nations pre.studied results, changes in human relation were examined with identifying the main several factors that bring greatest influence to the children's attachment and aggression. In conclusion, the children's attachment and aggression's the cause of the children's attachment and aggression were mainly from the maternal discipline and defiance upbringing.

Vibration test fixture is used in random vibration control testing. The specified reference spectrum should be transmitted equally to the specimen attachment points on the fixture. In most practical cases, however, spectrum at each of specimen attachment points may be quite different from the specified reference spectrum because of the dynamic characteristics of vibration test fixture. This paper proposes the method of experimental dynamic modification of fixture system for vibration test so that the reference spectrum can be transmitted to the specimen attachment points without distortion. The stiffness of mounts of specimen and the thickness of fixture are considered as design variables. The frequency response functions of specimen used for input data are obtained from vibration testing, and the frequency response functions of fixture are obtained from finite element modeling. The sensitivities of frequency response functions at specimen attachment points to the mount stiffness are derived from synthesis method of transfer function. And the sensitivities to the thickness of fixture are also derived from finite element modeling. The presented method is verified by computer simulation and vibration testing.

The purpose of this study is to investigate the relationship between the spectator experience and satisfaction with a focus on attachment and a sense of community. The survey was given to random spectators who watched KBO (The Korea Baseball Organization) games in 2018. With 189 surveyed participants, this study used exploratory factor analysis and reliability analysis to verify the reliability and validity of the measured variables. The hierarchical multiple regression correlation was employed as a statistical method for the hypotheses of this study. The findings showed that spectators' experiences have influences on satisfaction. Among the experience factors, education and entertainment affect attachment, and education has the only significant influence on a sense of community. In addition, spectators' attachment and a sense of community positively influence satisfaction. Attachment and a sense of community have a relatively mediated effect on spectators' experiences and satisfaction. This study confirmed the need for various spectator experiences at KBO games, and the importance of place attachment or a sense of community.

Purpose: The purpose of this study was to identify the characteristics and the related factors of attachment- oriented caretaking behavior in mothers who are breast-feeding their infants. Method: The subjects were 155 mothers who participated in a healthy breast-feeding contestin the Busan area. The data were collected from September 24, 2003, and were analyzed using SPSS WIN 10.0. Results: The mothers were highly affirmative in their attachment-oriented caretaking behaviors (total mean 2.59±.502 of a possible score of 3). Among the attachment-oriented caretaking behaviors (10 items), the scores for 6 items were higher than the average score and 4 items were lower than the average score. There were significant differences in the attachment-oriented caretaking behaviors according to level of education (p＜0.05), and planned duration of breast-feeding (p＜0.001). Mothers with university education who planned to breast-feed as long as the baby wanted had higher scores. Conclusions: The above results suggest that nursing interventions which are individualized and practical are needed to encourage the attachment-oriented caretaking behaviors essential to breast-feeding mothers.

Purpose: The main purpose of this study was to establish a nursing intervention data base to improve maternal attachment. Method: The first group of mothers( control group), experienced their first physical contact with their infants after being discharged from the hospital. The second group (experimental group) practiced early initial mother-infant postpartum contact known as the most sensitive period for founding maternal-infancy attachment. The subjects of this study gave birth to normal infants at M hospital from Aug.25 to Sept.30, 2004. During the same time, data was collected through direct observation, with instruments designed by Cropley et al., to assess the behaviors of normal attachment. The statistical methods for data analysis were percentage, mean, standard deviation and t-test with an SPSS program. Result: The group practicing initial mother-infant contact, showed a higher degree of physical and functional bonding than the group experiencing the first contact after discharge from the :10spital (control group)(p<.0l). The group practicing initial mother-infant contact, showed higher degrees of bonding attachment assessments than the group experiencing their first initial contact after their discharge from the hospital(p<.01). Conclusion: The group practicing early mother-infant contact, showed more maternal-infant interaction than the group experiencing their initial contact after their discharge from the hospital. These results show that maternal attachment behavior increases according with an early initial mother-infant contact.
