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.

The objective of this study is to understand the relationship between type of advertising and brand attachment. We divide advertising type into loss and gain frame and examine the effect on brand attachment, The effect of scarcity advertising on brand attachment and the effects of interaction effects on brand attachment were examined. The results showed that the effect of the loss and gain frame on brand attachment was not statistically significant. It also showed that scarcity was not emphasized or emphasized or had no effect on brand attachment. That is, the more emphasis on gain in advertising frame and the less pressure on scarcity, the more effective ad type for brand attachment.

The purpose of this research is to explore the self-concept and school life adjustment based on group classification of attachment types with parents, teachers and peer groups among 6th grade students at elementary schools. The findings suggest that attachment is highest with one's mothers, followed by peer groups, fathers and teachers. This is in accordance with the overall tendencies of children to be attached to their parents, teachers, peer groups, according to their self-concept and school life adjustment. In addition, the tendency of attachment with parents, teachers, and peer groups according to gender is not meaningful except for peer-group affection between boys and girls. Furthermore, an integrated attachment type is ranked highest, followed by parents attachment type, peer attachment type, and unstable attachment type, in order based on cluster analysis. Finally, each attachment group among students showed meaningful differences in socio-demographic variables, self-concept, and school life adjustment.

Statement of problem: It could be hypothesised that attachments, which provide more retention against vortical and horizontal dislodgement, will be associated with more favorable parameters of oral function. Purpose: This study was to provide data of initial retentive force and retention loss of different bar attachment systems recommended for use with maxillary implant overdentures. Material and method: 4 implants were placed in the anterior region of edentulous maxilla, five different systems of bar attachment were fabricated as follows: cantilevered Hader bar using clips (Type 1), Hader bar using clips without cantilever (Type 2), Hader bar using clip and ERA attachment orange male (Type 3), Hader bar using clip and ERA attachment white male (Type 4), and Bar using magnets (Type 5). Each samples were placed in the universal testing machine for determination of retentive forces(at initial and after every 200 cycles up to 1,000 cycles). Results and Conclusion 1. Attachment type 1 showed the biggest initial retentive force followed by type 3, type 2, type 4, and lastly type 5(P<0.001). 2. After 1,000 cycles of repeated removals of attachments, significant loss of retentive forces was taken place except for attachment type 5. 3. After 1,000 cycles of repeated removals, the loss of retentive force between type 1 and type 2, which used Hader bar and clip attachments. was greater in type 1 that had wider clip formation. And between type 3 and type 4, which used ERA attachments, the loss of retentive force was greater in type 4 that had white male attached (P<0.001). 4. After 1.000 cycles of repeated removals, attachment type 3 showed the biggest retentive force followed by type 2, type 4, type 1 and lastly type. 5. There was no significant difference between attachment type 3 and 4, and type 4 and 1(P<0.001).

This study examined significant factors explaining college students' place attachment to their childhood homes, developed the scale of that, and proposed statistically significant models to explain their place attachment to those home environments. We conducted a questionnaire survey with 32 items. Responses from 358 Michigan State University students were analyzed statistically. From the explanatory and confirmatory factor analysis, 31 items under 4 valid factors named Place dependence, Affection, Rootedness, and Place identity were obtained. This study additionally adapted six types of place attachment to childhood homes from Hess (1997), and examined these types. Idealization (Type1), affection (Type3), and transcendence (Type5) were chosen most often. Finally, this study explored the relationships between housing satisfaction and (1) the four place attachment factors and (2) the six types of place attachment. Results showed the four place attachment factors were more strongly related with housing satisfaction.

The purpose of this study is to investigate the relationship between adult children's perceived interaction pattern with their parents and their marital satisfaction. The subjects are a total of 646 male and female who been married for 3 years or less, living in Seoul, and whose fathers or mothers are still alive. The questionaire, including of attachment, autonomy, marital satisfaction scales, are distributed to collect the data. The main results are as follows: 1. Intimate-Dependent type is 31% each in relation to fathers and mothers. Distant-Independent type is 30% in relation to fathers, 27% in relation to mothers. Balanced type is 21% in relation to fathers, 23% in relation to mothers. Undeveloped type is 18% in relation to fathers, 19% in relation to mothers. 2. there is interaction effect between parental sex and adult children's sex as related to attachment levels, autonomy levels. 3. There is statistically significant difference among attachment-autonomy patterns as related to adult children's marital satisfaction. 4. Attachment and autonomy in relation to fathers and attachment in relation to mothers affect sons' marital satisfaction positively. Attachment in relation to fathers and mothers affect positively to daughters' marital satisfaction.

Most articles of Reactive Attachment Disorder reported Disinhibited Type children adopted from other countries. Reports from only Turkey and Korea focused on Inhibited Type of Reactive Attachment Disorder children whom raised by their own parents and whose symptoms are very similar to Autistic Disorder. Since articles of treatment of Reactive Attachment Disorder, especially for Inhibited Type are very rare, this article informed the author's experiences of treatment for Korean Reactive Attachment Disorder children since 1987. To treat Reactive Attachment Disorder patients and their parents, three important areas must be included : 1) to make a therapeutic environment for a Reactive Attachment Disorder child, 2) to make an attachment between Reactive Attachment Disorder child and his/her mother through individual play therapy, filial therapy, and group therapy with sibling or peer, 3) to catch up developmental delay by speech therapy, cognitive therapy and therapeutic education. This treatment methods can be more easily and more effectively applied to Korean patients than other methods from western countries including USA or England.

The purpose of this study is to examine the importance of healthy attachment formation by examining the effects of dental hygiene students' adult attachment patterns on depression, self-esteem, empathy, and career choice, and to present basic data for career guidance that considers individual characteristics. Students enrolled in the dental hygiene department at a university in Daejeon were the subjects of this study, and data were collected from September 14 to October 14, 2020 through self-reported questionnaires. Frequency analysis, ANOVA, correlation analysis, and multiple regression analysis were performed. As a result of classifying adult attachment styles into three types, out of a total of 158 people, 62 (39.2%) had the avoidant attachment style, 56 (35.4%) had the secure attachment style, and 40 (25.3%) had the anxious-ambivalent attachment style appear. Self-esteem according to attachment type (F=26.224, p<0.0001), empathy (F=3.944, p<0.05), depression (F=12.702, p<0.0001), career indecisiveness (F=4.367, p<0.05). Based on the results of identifying the sub-factors that affect the dental hygiene and adult attachment styles of students with depression, self-esteem, empathy and career choice, this study intends to use them as reference materials for career decision taking into account individual characteristics.

The purposes of this study are to investigate the relationship between university students' romantic and parent attachment in attachment security and to examine the relationship among romantic attachment, parent attachment and filial obligation for generational transition. Major results of this study are as follows: first, the level of attachment anxiety in female students is higher than male students. 25.1% of the subjects is classified into a secure type and 74.9% is classified as an insecure type. Second, female subjects feel strong attachment to their mothers than male subjects. Third, romantic attachment of female students is related to attachment to their fathers. Fourth, male subjects feel more filial obligation than female subjects. Finally, their romantic and parent attachment are positively related to their filial obligation. Variables that explain male students' filial obligation are ones of 'giving economic aid to parent' and 'the extent of attachment to their fathers'. A variable accounting for female students' filial obligation is 'the extent of attachment to their mothers'.

The aim of this study was to identify the awareness of the animal registration system, as well as to determine if there is a difference according to the types of pet attachment of consumers raising companion dogs. For this purpose, 250 data were collected by conducting an online survey and analyzed the data using SPSS 24.0. As a result of the study, pet attachment was identified as a companion attachment and emotional attachment. According to the form of attachment to dogs, the consumer types were categorized into three groups: type of simple cohabitation(25.6%), type of close companion(30.4%), and type of strong bond(44.0%). It was found that there are statistically significant differences in the relationship between the recognition and registration of the animal registration system for each consumer type. In addition, there were statistically significant differences in the perception and preference of the animal registration system depending on the type of consumer. This study has significance in that it suggests the effective direction of developing the consumer-oriented animal registration system.
