Objectives This survey study was conducted to investigate the effect of smoking on drinking alcohol, depression, anxiety and impulsiveness. Methods The survey participants were 925 residents over 20 years of age in Gwanak-gu, Seoul. Subjects were divided into smoking and non-smoking groups, and all completed the Korean Version of the Alcohol Use Disorder Identification Test (AUDIT-K), the Beck Depression Inventory (BDI), the Barret Impulsiveness Scale (BIS) and the State-Trait Anxiety Inventory (STAI) to identify patterns of the alcohol consumption and smoking, and to assess levels of depression, anxiety and impulsiveness. Results The number of subjects with problem drinking was significantly higher in smokers (n=58, 37.2%) than non-smokers (n=81, 11.1%), and there was also a significant difference between smokers and non-smokers on the BDI. However, there were no significant differences between smokers and non-smokers on either the BIS or the STAI. When smokers with problem drinking (Smk_Alc) and smokers without problem drinking (Smk_non-Alc) were compared, the Smk_Alc subjects were found to have higher BDI and trait anxiety scores than the Smk_non-Alc group. Conclusion The results of this study indicate that smoking is closely related to drinking alcohol and suggests that the more frequently people smoke, the more likely they will drink alcohol due to depression and anxiety. It may therefore important for smokers to control depressive mood, anxiety and impulsivity.

Purpose: To compare the corneal endothelial cell changes in both eyes of Korean patients with clinically unilateral exfoliation syndrome using specular microscopy. Methods: A total of 144 eyes of 72 patients diagnosed with clinically unilateral exfoliation syndrome at Yeungnam University Hospital between March 2000 and February 2011 were retrospectively reviewed. Comparisons of corneal morphometric analysis were made including endothelial cell density, coefficient of variation, hexagonality, and central corneal thickness between the exfoliative and fellow non-exfoliative eyes in 72 patients with naive unilateral exfoliation syndrome. If patients received intraocular surgery during the follow-up periods, the number of intraocular surgeries and changes of the above-mentioned morphometric analysis were evaluated. Results: The paired exfoliative and fellow non-exfoliative eyes did not differ in endothelial cell density (2587.0 ± 391.0 vs. 2626.8 ± 354.6 cells/mm2, p = 0.321), in the coefficient of variation of cell size (35.9 ± 5.1 vs. 37.1 ± 4.7%), hexagonality (59.5 ± 7.3 vs. 57.8 ± 6.3%), and central corneal thickness (530.5 ± 37.6 vs. 532.0 ± 35.2 μm). However, the exfoliative eyes had significantly higher values for the number of intraocular surgeries (0.97 ± 0.78 vs. 0.28 ± 0.48, p < 0.001) and decrement of corneal endothelial cells (410.9 ± 538.7 vs. 19.0 ± 284.5 cells/mm2, p = 0.007). Conclusions: There were no significant morphologic differences in corneal endothelium between exfoliative eyes and fellow eyes in the present study. However, the authors suggest that specular microscopic examination be performed before intraocular surgery in eyes with exfoliation syndrome when considering the higher frequency of intraocular surgeries and the resultant corneal endothelial damages observed in the present study.

Objectives This study was conducted in order to investigate characteristics of temperament, depression, anxiety, attention, and impulsivity in adult males with Attention Deficit/Hyperactivity Disorder (ADHD) and internet addiction tendency. Methods The survey participants were 181 (121 patients and 60 healthy control subjects) adult males older than 19 years of age in Chung-Ang University Hospital and Gongju National Hospital. Subjects were divided according to ADHD with internet addiction tendency (AI), pure adults with ADHD (AD), and healthy control subjects (HC). All groups completed the Adult ADHD Scale (AADHD), Wender-Utah ADHD Rating Scale (WUADHD), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), the Korean Version of Young Internet Addiction Scale (YIAS-K), Barratt Impulsiveness Scale (BIS) and Temperament Character Inventory-Revised Short version for identification of relationship between ADHD and internet addiction tendency. Results AI groups were found to have higher AADHD, WUADHD, BDI, YIAS-K, and Novelty Seeking scores, compared to the AD and HC groups. The Cooperativeness score of the AI group was significantly lower than that of the AD group and HC group. The BAI and BIS scores of the AI group and AD group were significantly higher than those of the HC group. The Self-Directedness scores of the AI group and AD group were decreased, compared to the HC group. YIAS-K scores were partially related to BDI scores in the AI group. Conclusion The results of this study indicate an association of higher score of BDI with internet addiction tendency in adult patients with ADHD. Management of temperament characteristics, depression, anxiety, attention, and impulsivity may be important for adults with ADHD and internet addiction tendency.

As the number of personal mobility users increases, it is essential to protect both personal mobility users and car drivers. Although existing supervised learning-based object detection methods can recognize personal mobilities, processing for data collection, labeling, and training is time-consuming and expensive whenever new forms of personal mobilities come to the market. Anomaly detection-based methods are proposed to learn normal patterns and detect abnormal patterns without prior training. This study proposes a new approach to personal mobility user recognition using deep learning-based anomaly detection in dynamically changing driving environments. The proposed approach consists of Human detection, Cropping and Anomaly detection modules. The Human detection module detects human regions. The Cropping module removes unnecessary areas and performs a preprocessing. The memory-based Anomaly detection module distinguishes between pedestrians and personal mobility users. Based on the proposed anomaly detection method, augmented reality (AR) visualization in the head-up display (HUD) is proposed for effective driving assistance. Since it is possible to distinguish pedestrians and mobility users effectively, the AR HUD-based visualization can assist the driver to pay more attention to the mobility user.
