PURPOSE. The aim of this study was to compare the retention of mini implant overdenture by the number, the type of magnetic attachment, and the directions of applied dislodging force. MATERIALS AND METHODS. The experimental groups were designed by the number and type of magnetic attachment. Twenty samples were tested with Magden implants. Each attachment was composed of the magnet assembly in overdenture sample and the abutment keeper in a mandibular model. Dislodging forces were applied to the overdenture samples (50.0 mm/min) in 3 directions. The loading was repeated 10 times in each direction. The values of dislodging force were analyzed statistically using SPSS at 95% level of confidence. RESULTS. The retentive force of group 2 was greater than that of group 1 in both types of attachment in every direction (P < .05). Oblique retentive force of flat type magnetic attachment was higher than that of cushion type attachment in both groups (P < .05). In group 1, oblique retentive force showed the highest and anterior-posterior retentive force showed the lowest value in both attachment types (P < .05). In group 2, both types of attachment showed the lowest retentive force with anterior-posterior direction of dislodging force (P <.05). CONCLUSION. Proper retentive properties for implant overdenture were obtained, regardless of the number and type of magnetic attachment. In both types of magnetic attachment, the greater retentive force was attained with more implants. Oblique retentive force of flat type magnetic attachment was greater than that of cushion type. Among all subgroups, anterior-posterior retentive force was the lowest among three different directions of dislodging force.

This study aimed to investigate the influence of mother's responsive/restrictive parenting and peer attachment on academic stress in school-aged boys and girls. The participants were 493 5th, 6th graders from five elementary schools in Daegu and Gyeongbuk province. The collected data were analyzed through a t-test, multiple regression, hierarchial regression using SPSS Win 19.0. The results are as follows. (1) Level of academic stress of school-aged girls was higher than boys. (2) Responsive parenting of mothers was the most powerful explanation in academic stress of school-aged boys. However restrictive parenting of mothers was the most powerful explanation in academic stress of school-aged girls. (3) In boys, responsive parenting of mothers influenced their academic stress but peer attachment didn't influence the boys academic stress. In girls, responsive parenting of mothers and peer attachment influenced their academic stress, and interaction effects of responsive parenting of mothers and peer attachment on academic stress was observed. (4) Both boys and girls, restrictive parenting of mothers and peer attachment had influences on academic stress. And interaction effects of responsive parenting of mothers and peer attachment on academic stress was not observed.

This research examines the effects of parental attachment as a family-related variable, and depressive mood as an individual variable on anger expression style among Korean college students. Anger expression style was divided into three domains including anger-in, anger-out, and anger-control. The data were collected from 437 college student respondents using a self-administered questionnaire. The results demonstrated that male students displayed higher levels of anger-control compared to females, but no gender-related difference in the level of anger-in and anger-out. In addition, anger-control was positively associated with parental attachment. However, anger control in terms of anger-in and anger-out were negatively related to parental attachment and positively linked to depression. Additionally, parental attachment demonstrated a negative correlation with depressive mood. Multiple regression results indicated that after controlling for the effect of gender, anger-control expression style was influenced by parental attachment but not by depressive mood. In addition, anger-out and anger-in expression styles were influenced by depressive mood but not by parental attachment. Finally, implications for educators and clinicians working with college students and their family are discussed along with some suggestions for future research.

This study examines the effects of parent-child attachment across the child's life from a life-span developmental perspective. The study investigates the effects of a child's attachment to his or her mother in childhood on his or her school attachment as an adult student and explores the role of self-esteem as a mediator of the relationship between these two variables. A total of 529 S Cyber University students taking social welfare classes participated in this study. These students completed a questionnaire about their present level of self-esteem, attachment to their mother in childhood, and school adjustment. According to the SEM results, adult students' self-esteem fully mediated the relationship between their mother-child attachment in childhood and their school adjustment in adulthood. Attachment security for the mother in childhood was related to the child's own internal working model, and positive self-esteem was related to school adjustment.

Bone graft and guided tissue regeneration have been used for the regeneration of periodontal tissue which is the ultimate goal of periodontal treatment. Recently, it was reported that some kind of growth factors were used for regeneration. Platelet rich plasma was researched that it could increase the density of bone and the rate of bone regeneration. For that, 25 patients which have pocket depth more than 5mm at any of 6 surfaces, of healthy patient without any systemic disease were treated. $Biogran^{?}$ Were grafted into 14 infrabony pockets as controls, and $Biogran^{(R)}$ with PRP were inserted into 31 infrabony pockets. And then, follwing evaluations were made at the end of 1, 3 and 6 months. 1. There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level at preoperation(p>0.05). 2. Decrease in probing pocket depth were reduced to 3.32mm for experimental group and 2.71mm for control group. The decrease was evident at the end of 1 month, they were 2.97mm and 2.29mm,and it was statistically difference(p<0.05). 3. Gingival recession was increased by 0.55mm in experimental group and 0.50mm in control group, it was evident at the end of 1 month. And it was statistically difference(p<0.05). 4. Minimum probing attachment level was increased by 0.35mm in experimental group and 0.36mm in control group, it was statistically difference(p<0.05). 5. Maximum probing attachment level was decreased by 3.19mm in experimental group and 2.93mm in control group, it was statistically difference(p<0.05). 6. There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level(p>0.05). There was statistical difference in decrease of pocket depth between pre-operation and 1 month after post-operation(p<0.05). In conclusion, bone graft using $Biogran^{?}$ and bone graft using $Biogran^{?}$ With platelet rich plasma were both effective in treatment of infrabony pocket, bone graft using $Biogran^{?}$ With platelet rich plasma was more effective in early soft tissue healing.

Purpose. The purpose of this study was to compare the type and frequency of prosthetic complications associated with attachment types for implant overdenture. Material and methods. In this retrospective study, 38 patients (mean age, 63.5 years) have been treated with implant overdentures from 2007 to 2014. Ten patients received a bar-clip attachment. Eleven patients had received a milled bar with Locator attachment. Seventeen patients had received a Locator attachment. The mean follow-up period was 36.9 months (range, 15-83 months). The type and frequency of prosthetic complications was recorded. The frequency was analyzed to determine the statistical difference among the 3 different attachments by using one-way ANOVA (${\alpha}=.05$) and Bonferroni post hoc method at a 5% level of significance. Results. The total number of prosthetic complications was higher in the bar-clip attachment (55 events) than in the milled bar with Locator attachment (39 events) and the Locator attachment (34 events). There were no statistically significant differences, and the most common prosthetic complication was the loss of retention. In the bar-clip attachment group, the average frequency of prosthetic complications was 3.0 events per prosthesis during the first year. In the milled bar with Locator attachment and Locator attachment groups, the average frequencies were 1.45 events and 2.35 events, respectively. Statistically significant differences were observed in the frequency of the complication. (p = .043) Conclusions. Compared to the bar-clip attachment, implant overdentures that use milled bars with the Locator attachment have a significantly lower incidence of prosthetic complications in the first year of follow-up after placement.

Purpose: Coronavirus disease 2019 (COVID-19) has spread widely throughout the world, causing psychological problems such as fear, anxiety, and stress. During the COVID-19 pandemic, pregnant women have been concerned about both their own health and the health of their fetuses, and these concerns could negatively affect maternal-fetal attachment. Thus, this study aimed to explore the level of COVID-19 stress, resilience, and maternal-fetal attachment among pregnant women during the COVID-19 pandemic, and to identify factors influencing maternal-fetal attachment. Methods: In total, 118 pregnant women past 20 weeks gestation were recruited from two maternity clinics in Daegu, Korea, to participate in this descriptive correlational study during COVID-19. The factors influencing maternal-fetal attachment were analyzed using hierarchical multiple regression analysis. Results: The mean scores for COVID-19 stress, resilience, and maternal-fetal attachment were 57.18±10.32 out of 84, 67.32±15.09 out of 100, and 77.23±9.00 out of 96, respectively. Nulliparous pregnant women reported greater maternal-fetal attachment than multiparous pregnant women (p=.003). Religious pregnant women also reported greater maternal-fetal attachment than non-religious pregnant women (p=.039). Resilience (β=.29, p=.002), COVID-19 stress (β=.20, p=.030) and parity (β=-.17, p=.047) were factors influencing maternal-fetal attachment, and these factors explained 26.4% of the variance in maternal-fetal attachment (F=10.12, p<.001). Conclusion: Converse to common sense, COVID-19 stress exerted a positive influence on maternal-fetal attachment in pregnant women during the COVID-19 pandemic. Healthcare providers need to recognize the positive influence of COVID-19 stress and implement intervention strategies to strengthen resilience in pregnant women to improve maternal-fetal attachment.

The purpose of this study was to investigate the relationships between female adolescents's relationships with their parents, psychological well-being, and attitudes towards eating. General characteristics of the subjects such as their school grades, and religion, and their parents' level of educational, marital status, and income were also analyzed in relation with the three major variables. Female adolescents' psychological well-being consisted of two indices: self-esteem and depression. The sample of this study consisted of 419 female students from 4 middle schools and 2 high schools located in Jeollabuk-Do province and the data were collected by using the method of self-administered questionnaires. The results of the analyses showed that there were significant differences in the level of parental attachment across parents' marital status, father's education level, and family income. Participants' psychological well-being levels were also different according to their grades, parents' marital status, and father's education level and income; and the level of eating attitude was different according to their school grades. The correlation analyses results indicated that parental attachment was positively related to self-esteem but negatively to a depressive mood. In addition, female students' eating attitudes were negatively associated with parental attachment and self-esteem, but positively with a depressive mood. Finally, multiple regression analysis found that a negative eating attitude was strongly influenced by a depressive mood, while parental attachment seemed to influence eating attitude indirectly through a depressive mood.

The present study evaluated of regeneration effect of platelet rich plasma on the treatment of classII furcation involvement, with allograft in humans. The control was treated without bioabsorbable membrane, and the test was treated with bioabsorbable membrane. Pocket depth, clinical attachment level, and gingival recession were measured at baseline, postoperative 3, 6months. Both groups were statistically analyzed by Wilcoxon signed Ranks Test & Mann-whitney Test using SPSS program (5% significance level). The results were as follows: 1. The change of pocket depth and clinical attachment level in both groups was decreased significantly at 3, 6months.(p<0.05) 2. The change of gingival recession in both groups was increased significantly at 3, 6months than at baseline.(p (0.05) 3. The change of pocket depth and clinical attachment level in both groups was increased significantly at 3, 6months, but there were no statistically or clinically significant differences with both groups. 4. The change of gingival recession in both groups was increased significantly at 3, 6months, but there were no statistically or clinically significant differences with both groups. 5. The significant reduction of the pocket depth and clinical attachment level exhibited marked changes at 3 months in both groups. In conclusion, the results of this study suggest that there are no statistically or clinically significant differences between with and without bioabsorbable membrane on treatment of classII furcations using allograft and PRP

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.
