Objectives : Studies have reported differences between depressed adults and controls in quantitative measures of EEG alpha asymmetry, but, there are few using Korean subjects. So, the present study compared EEG regional alpha asymmetries of patients having major depressive disorder(MDD) and normal controls. Methods : The subjects in this study were 11 unmedicated unipolar depressed patients and 11 non-depressed, age matched controls. Resting EEG(eyes closed and eyes open) was recorded from each participant using 8 scalp electrodes. Beck Depression Inventory(BDI), 17-item Hamilton Depression Rating Scale(HDRS), Zung's Self-Rating Depression Scale(SDS) and Spielberger's State-Trait Anxiety Inventory(STAI) were used to evaluate depression and anxiety symptoms. Results : The severities of depression measured by self-report questionnaires were positively associated with those of anxiety(state and trait) ; The subjects were both anxious and depressed. Anxious-depressed patients differed from controls in alpha asymmetry at T4 channels. They showed evidence of greater activation over right than left temporal site. Conclusion : These findings are consistent with the previousely reported alpha asymmetry of depressed patients with an anxiety disorder. The failure to find the evidence of reduced right parietal activity in depression is presumed to be due to opposing effects of comorbid anxiety on parietotemporal activity.

Purpose: The purposes of this study were to identify nursing students' levels of anxiety in simulation based nursing education and to understand the relationship of anxiety and personal satisfaction of simulation, self-efficacy, and clinical competence during simulation. Methods: This study was a descriptive study with 84 senior nursing students at a private university in South Korea. Level of anxiety was measured with STAI (the State- Trait Anxiety Inventory) prior to the stimulation practice. After the debriefing, satisfaction scores were measured with SSE (Satisfaction with Simulation Experience scale), self-efficacy scores with the modified measurement developed by Roh and Park, and scores for clinical skills with a scale developed by the Korea Association of Cardiopulmonary Resuscitation. Results: Nursing students exhibited moderate to severe anxiety in simulation practice (Mean 49.51, SD 8.60). Self-efficacy was negatively correlated to anxiety (r=-.25, p=.022). Conclusion: Decreasing students' anxiety levels needs to be addressed to increase the self-efficacy of the simulation practice.

Purpose: This study is to find relationship between cancer patient's spiritual health and the level of their anxiety and pain. Methods: From April 27 through May 11, 2012, a survey was conducted with 167 cancer patients hospitalized at a university hospital in Busan. Spiritual health was measured by the Spiritual Health Inventory developed by Highfield (1992). The instrument for anxiety measurement was the State-Trait Anxiety Inventory by Spielberger (1975) and that for pain was the Visual Analogue Scale (2009). The association between patients' characteristics and spiritual health, anxiety or pain degree were analyzed using the ANOVA test. The interrelationship between spiritual health, anxiety and pain was analyzed using Pearson's correlation coefficients. Results: The patients exhibited a moderate degree of spiritual health and anxiety and a mild level of pain. Patients' spiritual health significantly differed by their religion, education, monthly income of the family, illness conditions, physical conditions, metastasis, daily living and support. Their anxiety level was significantly different according to age, religion, education, illness conditions, physical conditions, metastasis, daily living, family/friends' support and use of analgesics. Significant differences were also found in the level of pain according to illness conditions, physical conditions, metastasis, daily living, family/friends' support and use of analgesics. We found a moderately negative correlation between spiritual health and anxiety. Anxiety and pain showed a positive correlation, and spiritual health and pain exhibited a negative correlation. Conclusion: To help cancer patients to manage their spiritual health, anxiety and pain, a program should be developed considering the primary factors discussed in this study.

Objective: Poor experience with Invisalign treatment affects patient compliance and, thus, treatment outcome. Knowing the potential discomfort level in advance can help orthodontists better prepare the patient to overcome the difficult stage. This study aimed to construct artificial neural networks (ANNs) to predict patient experience in the early stages of Invisalign treatment. Methods: In total, 196 patients were enrolled. Data collection included questionnaires on pain, anxiety, and quality of life (QoL). A four-layer fully connected multilayer perception with three backpropagations was constructed to predict patient experience of the treatment. The input data comprised 17 clinical features. The partial derivative method was used to calculate the relative contributions of each input in the ANNs. Results: The predictive success rates for pain, anxiety, and QoL were 87.7%, 93.4%, and 92.4%, respectively. ANNs for predicting pain, anxiety, and QoL yielded areas under the curve of 0.963, 0.992, and 0.982, respectively. The number of teeth with lingual attachments was the most important factor affecting the outcome of negative experience, followed by the number of lingual buttons and upper incisors with attachments. Conclusions: The constructed ANNs in this preliminary study show good accuracy in predicting patient experience (i.e., pain, anxiety, and QoL) of Invisalign treatment. Artificial intelligence system developed for predicting patient comfort has potential for clinical application to enhance patient compliance.
