This study aims to identify the object relations and PAD factors of Instagram users, apply the object relations to the emotional response (PAD) factors, and empirically study the structural relationship between these factors and satisfaction. To this end, we proposed a research model to which the four factors of object relations theory and the three factors of emotional response (PAD) theory that emphasize the emotions of users are applied. Surveys were conducted on the college students in Seoul and Suwon who had used Instagram. As a result of this study, the following conclusions can be drawn: Non-alienation has a significant influence on pleasure, arousal, and domination. Secure attachment does not have a significant influence on pleasure and arousal, while it does have on domination. Social ability does not have a significant influence on pleasure, arousal, and domination. Egocentrism has a significant influence on arousal, but not on pleasure and domination. Pleasure has a significant influence on arousal and satisfaction. Arousal has a significant influence on domination and satisfaction. Domination has a significant influence on satisfaction. In conclusion, when emotions are shared among the users of Instagram, not alienated, it affects their satisfaction.

The present study was performed to evaluate the relationship between the serotype or the genotype of Actnobacillus actinomycetemcomitans (A. a.) and the severity of periodontal disease. Total 64 A. a. clinical isolates were sampled from 46 sites of 20 subjects classified into the group I (1 periodontally healthy subject, 2 gingivitis patients, 5 ealry adult periodontitis patients), group II (3 moderatelly adult periodontitis patients) and group III (1 advanced adult periodontitis patient, 8 RPP patients). Southern bolt hybridization (fingerprinting) patterns of the five reference strains, A. a. strain ATCC 29523 (serotype a), ATCC 29522 (Serotype b), ATCC 43719 (serotype c), IDH 781 (serotype d) and IDH 1705 (serotype e), were used as the five basic genotypic patterns (A, B, C, D, E). NT type was designated as one which did dnot represent any of those five basic types. The serotypes were determined by ELISA technique with the serum samples from pre-immunized rabbit. Based on subject-based analysis, it was noted that genotypes A and C, NT, and B, D, E were significantly related to the disease groups I, II, and III, respectively. It was also noted that both the serotypes a and c were significantly related to the disease group I and II, while serotypes were significantly related bm), and serotypes b and nd were frequently found in sites with severe attachment loss (LA>6mm). The results indicated that the significant relationship can be delineated beteen the genotypes and the serotypes of Acinobacillus actinomycetemcomitans and the periodontal disease severity. The results also indicated that genotyping can provide more detailed information on its relationship with the disease severity based on both the patient-based and the site-based analyses.

The purpose of this study is to develop the Internet vulnerability index of adolescents. To do this, we used the original data of long - term follow - up survey for the internet overdependency cause analysis conducted by NIA in 2018, and analyzed the correlation between alternatives of internet vulnerability index and personal psychology by using linear regression analysis. Factor analysis showed that the relationship with the surroundings was indexed by adding 9 items to positive factors such as family acceptance, peer attachment, and teacher favorability. The relationship between the surroundings and self - stigmatization is confirmed, and the relationship between the surroundings and the Internet fragility is predicted to be negatively related, and the digital capacity is also assumed to be negatively correlated with the Internet vulnerability. In order to develop the specific form of the Internet vulnerability index, personal psychology and linear regression analysis were conducted. As a result, positive factors and R value of personal psychology were increased when considering the relationship with the environment and the digital capacity rather than the Internet overdependency model. Based on these implications, we discussed the implications and limitations of this study.

Purpose: Although the term "transition to motherhood" is commonly used in research, the concept is not clear. This study, hence, was conducted to clarify the concept of "transition to motherhood." Methods: The concept analysis framework developed by Walker and Avant is used to analyze the concept of transition to motherhood. Results: Transition to motherhood is defined as the physical, psychological, social, and relational (mother-baby relationship/interpersonal relationship) changes that happen to a woman after pregnancy and delivery of a baby. The attributes of the transition to motherhood include: 1) adapting to physical changes after pregnancy and childbirth; 2) experiencing various psychological changes; 3) changing of her social perception from being a woman to someone's mother; and 4) forming and developing a relationship with the newborn, adjusting priorities, and redefining the relationship between family and others. Meeting the newborn is regarded as an antecedent of the transition to motherhood. Redefining identity and physical image, ensuring mother's well-being, maternal attachment, and confidence in the maternal role are regarded as consequences of the transition to motherhood. The concept was clarified by the presentation of model, borderline, and contrary cases. Conclusion: The significance of this study lies in the clarification of the concept of transition to motherhood and defining its attributes. It is recommended that tools be developed to measure transition to motherhood based on the results of this study. Furthermore, nurses and midwives can use study findings to better understand the concept of transition to motherhood in providing care and support to mothers who experience it.

In recent years, the number of love stories in Japanese TV series are decreasing. Comparing this with Korean popular TV series in Japan, it was found that Korean TV series have the following differences. In the Japanese series, the main characters were mostly from common origin. The conflicts within each relationship stage illustrated the conflicts between characters and their surroundings, as well as the conflicts which commonly arise in real life, that with the self. Confessions of love in the Japanese series used simpler expressions. Some couples did not even say "I love you". Further, when love was threatened, rarely was deep attachment shown. There were even cases where the main characters did not end up as a couple. On the other hand, there often existed a class difference between the male and female main characters in the Korean series and conflicts mostly arose from differences of environment, illness, love rivals, and etc. Every couple verbally confessed their love and they used more passionate expressions of love than in the Japanese series, and when love was threatened no man backed down and each showed his deep attachment. Finally, there were happy endings for everyone even after the many complications.

Conduct disorder has been subclassified by the symptom characteristics of socialization, aggression, or age of onset. In ICD-10, ‘Conduct disorder confined to family context’ has been developed as a distinct subtype. Which delineates the conduct problems which take place only in the family and related situation. These authors experienced a case which presents a child who shows aggressive and violent behavior to his parent and brother, severe tamper tantrum and destructiveness only in family. By through history taking, observation and treatment after admission, we could find that insecure and ambivalent attachment between parent and child due to chronic neglect and abuse, and inconsistent parental behavior contribute to many behavioral and emotional problems of this child. We reviewed the relationship between conduct disorder and family pathology and treatment strategy for conduct disorder with family problems.

This study was conducted to recognize the need for diet and nutrition education to correct body-shape and eating habits that lead to eating disorders in college students. The relationship between diet and obesity was confirmed. Approximately 405 (male 46.4%, female 53.6%) students were evaluated by questionnaire in September 2014. The statistical program SAS (ver. 4.3) was used to evaluate the Chi-squared, F and T-value. The correlation between eating disorder risk and eating habits was evaluated by Pearson's correlation. Body type recognition was classified into nine steps up the body fatty (9) to skinny (1) to show their body. Eating disorder risk (KEAT-26) was composed of F1 (attachment factors for weight loss), F2 (attachment factors for binge eating, and food), and F3 (adjustment factor to eating their will. The risk of eating disorders in male 73.4% of low risk, in female 61.3% (p<0.05). According to body mass index, underweight groups recognized in the normal weight (53.7%), normal weight group was in overweight (29.1%) (p<0.001). According to body-type, the overweight group had a higher risk of eating disorders (68.2%). The KEAT-26 showed that the overweight and obese group were high-risk in F1 & F2, while the underweight group was high-risk in F3 (p<0.001). Recognized overweight showed the dangers of eating disorders, proper recognition of body-type and body mass index required. Tendency to seek a balanced diet was associated with eating disorders, no-imposed adequate diet for nutritional education would be made. Proper nutrition education for males is needed depending on the increased incidence of male eating disorders.

The purpose of this study was to verify the difference of middle school students' eating disorder behavior and scholastic adjustment according to the gender and weight group and evaluate correlations between their eating disorder behavior and scholastic adjustment. A survey was conducted in middle school second graders attending five schools located in Seoul. Results from 355 questionnaire sheets were utilized for statistical analysis, and the results were gained as below: With regard to eating disorder behavior by gender, female students showed more eating disorder behavior than male students (p < 0.01); however, scholastic adjustment did not indicate significant differences by gender. According to the result of analyzing scholastic adjustment according to the weight group, the obese group showed lower scholastic adjustment (p < 0.05) and adjustment to studying (p < 0.01) than other groups; however, the eating disorder behavior, attachment to school, and adjustment to school did not indicate significant differences. According to the results of analyzing scholastic adjustment by eating disorder group, the normal group showed higher adjustment to studying than the risky group (p < 0.01). And scholastic adjustment, attachment to school, and adjustment to school did not indicate significant differences. The eating disorder behavior showed negative relationship with adjustment to studying. They showed more eating disorder behavior, their adjustment to studying became lower. Therefore, it is necessary to provide nutritional education at home and at school for them to have appropriate dietary habits as well as health education for them to maintain normal weight.

Teeth mobility is an important part of a periodontal examination, because it represents a function of the persisting height of the alveolar bone and the width of the periodontal ligament. The purpose of this study was to evaluate clinical difference in teeth mobility after treatment with the modified Widman flap and the undisplaced flap in humans. Twenty males with moderate periodontal disease were selected. The severity of periodontal disease was evaluated with sulcular bleeding index, pocket depth and attachment level and tooth mobility was measured with Periotest(Siemens Co., Germany) at the initial examination, 1, 2, 4, 6, 8 and 12 weeks following the modified Widman flap and the undisplaced flap operation using the split-mouth technique. The relation of mobility to clinical parameters was statistically analyzed by multiple regression and the change of teeth mobility according to healing process by independent t-test using SPSS program. The results were as follows: 1. There was a strong relationship between the Periotest value(PTV) and attachment level. 2. The change of teeth mobility in both flap procedures was increased significantly at 1 week post-op. and was decreased to preoperative level at 4 weeks post-op, in modified Widman flap and at 6 weeks post-op. in undisplaced flap. 3. The change of teeth mobility in premolar teeth group in undisplaced flap compared to modified Widman flap was generally increased but these changes were not statistically significant. The changes of teeth mobility in molar teeth group in undisplaced flap was increased significantly at 2 weeks post-op.. 4. The change of teeth mobility following undisplaced flap was increased significantly compared to that of modified Widman flap at 2 weeks post-op.
