Purpose: The purpose of this study was to determine the stress, depression, and fetal attachment of pregnant women who underwent infertility treatment, and to identify factors associated with fetal attachment. Methods: As a correlation survey design, data were collected from 136 pregnant women who underwent infertility treatment. Data were analyzed using ${\chi}^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: Stress, depression, and fetal attachment averaged $3.01{\pm}0.60$ (range of scale 1~5), $10.02{\pm}6.51$ (out of a possible 63), and $3.64{\pm}0.55$ (range of scale 1~5), respectively. Level of fetal attachment was higher when mother's age was less than 35, having other children, and having prenatal education experience. Lower score of depression and client's age less than 35 were significant factors affecting fetal attachment. Conclusion: Infertility is a life-affecting trauma for the individual, and personal and social changes due to infertility cause physical and psychological difficulties even after a successful pregnancy with infertility treatment. Therefore, prenatal management programs need to be developed giving consideration to the emotional and physical changes in order to promote physical and psychological stability in the women pregnant following infertility treatment.

Purpose: The aim of this study was to explore root shape abnormalities, to investigate the influence of root form abnormalities on periodontal attachment loss, and to gather basic data to assist in the diagnosis and treatment of aggressive periodontitis. Methods: From January 2010 to June 2012, a survey was conducted of all 3,284 periodontitis patients who visited the Department of Periodontology, Daejeon Dental Hospital, Wonkwang University School of Dentistry. Clinical parameters (probing depth, periodontal attachment loss, missing teeth) were measured and a radiographic examination was performed at the baseline. We classified the root shape abnormality of bicuspids and molars based on Meng classification. Results: The periodontal attachment loss was the highest at the maxillary first molar (6.03 mm). The loss of the second molar was prominent. Type V deformity was shown to be the most common in the second maxillary and mandibular molars (P<0.05). Type V root shape was associated with the highest attachment loss (P=0.01). Conclusions: Considering the small population and limited design of this study, definitive conclusions cannot be drawn. We suggest larger scale, methodologically more sophisticated studies that include normal controls and chronic periodontitis patients to clarify whether root form abnormalities are a potential risk factor for aggressive periodontitis.

Purpose: The purpose of this study was to explore the effects of a taegyo program on parents-fetal attachment and parenthood in first pregnancy couples (mothers and spouses). Methods: The research design was a nonequivalent control group pretest-posttest experiment. Study participants were 52 first pregnancy couples visiting two medium-scale obstetrics and gynecology clinics located in Gwangju. A total of 52 couples were assigned to the experimental group (25 couples) and the control group (27 couples). The experimental couples were provided with a taegyo program for 4 weeks. Data were analyzed by chi square test, t-test, and ANCOVA using the SPSS program. Results: Post-treatment maternal- fetal attachment, paternal-fetal attachment and motherhood significantly increased in the experimental group as compared to the control group, but post-treatment fatherhood, anxiety, blood pressure and pulse of participants in the experimental group showed no significant difference from those in the control group. Conclusion: From these results, it is suggested that the taegyo program has beneficial effects in enhancing parent-fetal attachment and motherhood in first pregnancy couples. Therefore, a taegyo program can be recommended as a nursing intervention program for first pregnancy couples.

PURPOSE. The aim of the present study was to compare the stress distributions on the dental implants, abutments, and bone caused by different overdenture attachment types under functional chewing forces. MATERIALS AND METHODS. The 3D finite element models of the mandible, dental implants, attachment types, and prostheses were prepared. In accordance with a conventional dental implant supported overdenture design, the dental implants were positioned at the bone level in the canine teeth region bilaterally. A total of eight models using eight different attachment systems were used in this study. All the models were loaded to simulate chewing forces generated during the centric relationship (450 N), lateral movement (400 N), protrusive movement (400 N), and also in the presence of a food mass unilaterally (200 N). Stress outputs were obtained as the maximum principal stress and the equivalent von-Mises stress. RESULTS. In all attachment types, higher stress values were observed in the abutments, dental implants, and bone in the magnet attachments in different loading conditions. The highest stress values were observed among the magnet systems in the components of the Titanmagnetics model in all loading conditions (stresses were 15.4, 17.7, and 33.1 MPa on abutment, dental implant, and bone, respectively). The lowest stress value was observed in the models of Zest and O-Ring attachments. CONCLUSION. The results of the present study implied that attachment types permitting rotation and tolerating various angles created lower stresses on the bone, dental implants, and abutments.

Providing visual information about the fetus to the mother by the ultrasound examination was found to be an effective nursing intervention to promote Maternal-Fetal Attachment. In keeping with the purpose of the study, to evaluate the effect of providing visual information by ultrasound on level of Maternal-Fetal Attachment, a non-equivalent experimental group quasi-experimental design was used. The data were collected using Cranley's Maternal-Fetal Attachment Scale(1981) with a research questionnaire that consisted of 16 items on general characteristics and 23 items on Maternal-Fetal Attachment from November 2, 2000 to August 11, 2001. Subjects were 126 pregnant women who were received visual information by ultrasound and 123 pregnant women who did not receive visual information by ultrasound after finishing examination. The data were analyzed by using the SPSS/PC+ window 10.0 version program. The results of this study were as follows: There was no statistical difference in general characteristics between both groups. The scores on Maternal-Fetal Attachment at second trimester show no statistical difference (t=1.123, p=0.263). The scores on Maternal-Fetal Attachment in both groups increased between the second trimester and third trimester. However, the increase was greater in the group receiving visual information by ultrasound as compared to the group which did not receive the visual information(t=-2.152, p=0.032). This result shows that providing visual information about the fetus by the ultrasound examination is effective in increasing Maternal-Fetal Attachment.

Purpose - In the major global markets, such as US and China, consumer ethnocentrism has been strengtened and there is a growing need for related study. This research aims to investigate the effects of national pride and national attachment on consumer ethnocentrism, using a nationally representative dataset from 2013 Korean General Social Survey. Based on the reviews of literature in social and political sciences, two dimensions of national pride were considered: national society pride which is based on positive evaluations on the nation's democracy condition or social security system, and national achievement pride which is based on positive evaluations regarding the country's achievements in the areas of technology, art, sports, and so on. Research design, data, and methodology - The authors developed a structural model in which two types of national pride, national society and achievement pride, are proposed to affect national attachment, thus influencing consumer ethnocentrism. 1,294 surveys were used for empirical analysis. The hypotheses were tested by utilizing SPSS 22.0 and AMOS 21.0. The unidimensionality of each construct and the nomological validity were supported from the results of factor analyses and correlation analysis. Results - It was found that both national society pride and national achievement pride have significant and positive effects on national attachment. Consumers who show stronger pride on the social systems or the global achievements of Korea are more likely to remain being a citizen of the country and support the country even in wrong. Also, there was a significant and positive relationship between national attachment and consumer ethnocentrism. Korean consumers who have stronger attachment to Korea tend to express higher ethnocentrism to protect Korean labor market and to promote economic development of the country. Conclusions - The findings of this study showed that companies and government need to emphasize the country's advanced social environments or global competitiveness in technology, sports, art, and so on, to boost national attachment. With a deeper understanding on the relationships among national pride, national attachment, and consumer ethnocentrism, the authors expect that both local and foreign companies in Korea will be able to develop more effective marketing strategies and to achieve sustainable competitive advantage.

Most tasks of the large vertical or ceiling structures have been carried out by human power. Those tasks require us much operation costs and times, safety devices, etc. So the need of automation for those tasks have been rising. That automation needs a wall-climbing mobile vehicle. Most former researches are things about attachment devices and moving mechanisms. A wall-climbing mobile vehicle must be designed by a method different from the case of the vehicle of the horizontal environment. That is because gravity acts as a negative role on the stability of a wall-climbing vehicle. In this thesis, the particular shape characteristics of a wall-climbing mobile vehicle are derived by the wall-environment modeling. In addition, some design constraints of the permanent magnetic wheel as an attachment device was studied. According to those requirements and constraints, one specific wall-climbing mobile vehicle was designed and some experiments were made on the attachment ability of that vehicle.
