Purpose: The aim of this study was to evaluate the Bonwill triangle of Korean using the cone beam computerized tomography (Cone-beam CT). Materials and Methods: 120 Koreans (60 males and 60 females) who visited Daejeon Dental College Hospital of Wonkwang University and who underwent the Cone-beam CT were selected. The Cone-beam CT images were analysed with Invivo 5.1 (Anatomage, San Jose, USA). After reorientation of axis, the intercondylar distance was measured by clicking both middle points of condyle. And the condyle-incisor distance was measured by clicking the middle point of condyle and contact point of the mandibular central incisor's incisal edge. The collected data were analysed using the SPSS Version 23.0 (IBM Inc., Armonk, USA) and statistical significance was verified by gender using independent t-test. Results: The mean intercondylar distance of Korean was 105.9 mm, and the male (108.3 mm) was statistically significantly larger than the female (103.4 mm). The mean condyle-incisor distance of Korean was 105.2 mm, and the male (108.1 mm) was statistically significantly larger than the female (102.3 mm). Conclusion: The mean intercondylar distance of Korean in this study was 105.9 mm that was smaller than well-known 110 mm of Caucasian and the male was statistically significantly larger than the female. Within the limitations of this study, it would be necessary to use the articulator which can adjust the intercondylar distance according to the individual for prosthodontic treatment of Korean.

The purposes of this study were to investigate Korean men that chose international marriage in terms of motivations, relationships with their spouses in terms of content and process, and quality changes by approaching them in a biography research method, as well as to look into the world of their specific experiences. Ten Korean men in international marriage participated in the study. In-depth interviews with them generated plenty of data. The analysis results of the data indicate that the instrumental nature was strong as for their motivation to marry a woman of a different nationality. They maintained partner relationships with their spouses until the exchange values became equal between them, when tension and conflicts started to happen. The ways they reacted to the crisis determined whether their marital relationships would continue or end. Most of the subjects that succeeded in maintaining their marital relationships deconstructed their own culture, reorganized it at the contact points with the culture of their spouses, and then moved to a new diaspora. The research implications emphasize an academic need to regard female marriage immigrants as a neo-diaspora in the global age. And suggestions were made as to intercultural education.

Objectives: An Increased level of psychophysiologic arousal and diminished physiologic flexibility would be observed in patients with panic disorder compared with a normal control group. We investigated the differences of psychophysiologic response between patients with panic disorder and normal control to examine this hypothesis. Methods: Ten Korean patients with panic disorder who met the diagnostic criteria of DSM-IV were compared with 10 normal healthy subjects. In psychological assessment, levels of anxiety and depression were evaluated by State-Trait Anxiety Inventory, Beck's Depression Inventory and Hamilton Rating Scale For Anxiety and Depression. Heart rate, respiration rate, electrodermal response, and electromyographic activity were measured by biofeedback system (J & J I-330 model) to determine psychophysiologic responses on autonomic nervous system. Stressful tasks included mental arithmetic, video game, hyperventilation, and talking about a stressful event. Psychophysiologic responses were measured according to the following procedures : baseline(3 min)-mental arithmetic (3 min)-rest (3 min)-video game (3 min)-rest (3 min)-hyperventilation (3 min)-rest (3 min)-talking about a stressful event (3 min). Results: The baseline level of anxiety and depression, electrodermal response (p=.017), electromyographic activity (p=.047) and heart rate (p=.049) of patients with panic disorder were significantly higher than those of the normal subject group. In electrodermal response, patient group had significantly higher startle response than the control group during hyperventilation (p=.001). Startle and recovery responses of heart rate in the patient group were significantly lower than responses in the control group during mental arithmetic (p=.007, p=.002). In electrodermal response of the patient group, startle response was significantly higher than recovery response during mental arithmetic (p=.000) and video game task (p=.021). Recovery response was significantly higher than startle response in respiratory response during hyperventilation. Conclusion: The results showed that patients with panic disorder had higher autonomic arousal than the control group, but the physiologic flexibility was variable. We suggest that it is helpful for treatment of panic disorder to decrease the level of autonomic arousal and to recover the physiologic flexibility in certain stressful event.

Using a nationally representative sample from three recent waves of the Korean Welfare Panel Study, this study examined the association between experiencing material hardship and suicidal ideation among low-income households in South Korea. Overall, we found that experiencing material hardship was associated with a higher likelihood of having suicidal ideation. We also found that, among individual items of material hardship, experiencing food insecurity or credit problems was associated with a higher likelihood of having suicidal ideation. Furthermore, we found that the association of experiencing material hardship with having suicidal ideation was more pronounced for male-headed or elderly-headed households. Policy implications to improve living condition among low-income households and reduce their suicide-related behavior were discussed.

The study was aimed at investigating the relationship between biomechanical properties of cervical muscles and smartphone addiction score in fifty healthy males using smartphone more than 60 minutes each day. The usage of smartphone was evaluated by smartphone addiction survey developed from Korean International Society Agency. Biomechanical properties of three major cervical muscles; splenius capitis, sternocleidomastoid and upper trapezius, were measured by Myoton, and conducted five parameters; frequency, decrement, stiffness, creep, and relaxation time. As results, all parameters had less than 2% of coefficient of variation(CV) between measurement intervals. Also, intra-class correlation coefficient(ICC) indicated a high reliability(ICC>.9, p<.01). Moreover, the smartphone addiction score was significantly different in frequency(r=.353, p<.05) and stiffness(r=.346, p<.05) on upper trapezius; in addition, in decrement(r=-.284, p<.05) and creep(r=.288, p<.05) on sternocleidomastoid. Especially, splenius capitis was closely related with the overuse of smartphone(frequency, r=-.368, p<.01; decrement, r=-.405, p<.01; stiffness, r=-.424, p<.01). In conclusion, this study implied that the overuse of smartphone is significantly related with the damage of cervical muscles, cervical pain, and headache; furthermore, Myoton can be used as an effective device to assess mechanical properties of cervical muscles.

Severe dental attrition causes pathological changes of the tooth, imbalanced occlusion, and functional and aesthetic complications and can also result in a decrease in occlusal vertical dimension that can incur temporomandibular joint and muscular complications. Before restoring the vertical dimension with full-mouth prosthetic restorations, it is important to determine the amount of vertical lifting through complete diagnosis. In this study, a 59 year-old male patient with generalized attrition and fracture of teeth was treated with full-mouth zirconia prosthetic restoration in order to recover vertical dimension and aesthetics. Through the analysis of physiologic rest position and inter-canine distance, the treatment was planned for lifting 3 mm in vertical dimension. Interim crown were fabricated after full-mouth wax up, having the patient use for 6 months. The final monolithic and bilayered zirconia restorations were completed. The patient showed satisfaction in function and aesthetics for 18 months of follow-up since delivering the final restorations.

Remarriages constitute an increasing proportion of all marriage in Korea. In 2010, 21.9% of marriage were remarriages for one or both partners. In spite of such increasing of remarriage, not much attentions were given the issues of remarriage in the academic circle of social welfare in Korea. This study is conducted to understand the nature of remarriage, the family structure in remarriage, the relationship between the boundary ambiguity and the family functioning in remarriage. Although boundary ambiguity is believed to be more problematic for remarriage families than first-marriage families and as such has been the topic of research in the U.S.A and other countries, few studies have focused on this topic in Korea. This study examined degree of boundary ambiguity of 125 samples of remerried women and their family functioning. Also, the study examined the relationship between the boundary ambiguity and the family functioning in remarriage. This study conceptualized boundary ambiguity as an incongruence between physical and psychological presence or absence of family members. The findings indicated that the majority of respondents(67.6%) were categorized as having both no psychological and no physical ambiguity. 19.8% of respondents were categorized as having physical ambiguity, 9.9% as having psychological ambiguity, and 2.7% as having both psychological and physical ambiguity. Statistically significant differences of family functioning in remarriage were found among four groups having different type of boundary ambiguity.

The aim of this study was to elucidate characteristics of ongoing and progressive gambling addiction. So a researcher reviewed existing studies on the gambling addiction and reflected the epistemological assumptions behind it. In this study, 4 men gamblers were participated and in-depth interviews were conducted, the data were analyzed using case studies. The results of this study were as followings; the process of gambling addiction was conducted based on a particular stage. In particular, we could find that the phenomenon of gambling addiction has 'concurrency' in each phase. Phenomenons often seen in each step and each other extraneous event were interpreted as mutually complementary meaning. Also they affected the transmission to next steps of gambling addiction.

Previously, the usage of monolithic zirconia in anterior restoration was limited because of problems such as the monotony of tones and shades which would compromise the outcome of esthetic purpose. Zirconia was merely used as a coping with additional porcelain veneering whereas porcelain chipping cannot be evaded. Recently, with the improvement of monolithic zirconia, the various translucency and tones made it possible to use zirconia for anterior restoration. In this case, a male patient of 63 years old received a full mouth rehabilitation with monolithic zirconia. After a period of time usage, the outcome showed a favorable result functionally and esthetically.
