Objective: As the elderly population increases, the proportion of neurocognitive disorder is increasing. Accordingly, research on cognitive intervention therapy to prevent neurocognitive disorder is also becoming active. In particular, this study attempted to evaluate changes in cognitive function before and after training and verify their effectiveness by implementing a computerized cognitive training program for patients with mild cognitive impairment. Methods: A computerized cognitive training program was conducted for 15 patients with mild cognitive impairment. It was conducted twice a week, 30 minutes, and 16 times for 8 weeks, and neurocognitive function was evaluated before and after training. The neurocognitive function tests are as follows; Seoul Neuropsychological Screening Battery, Korean version of Montreal Cognitive Assessment (K-MoCA), Clinical Dementia Rating (CDR), Korean Instrumental Activity of Daily Living (K-IADL), Korean Neuropsychiatric Inventory (K-NPI), and Memory Age-associated Complaint Questionnaire (MAC-Q). Results: There was a statistically significant improvement in memory domain after the implementation of the computerized cognitive training program, but no significant changes in attention, language ability, visuospatial function, and frontal lobe exec-utive function. Among the memory areas, the Seoul Verbal Learning Test: Delayed Recall, Rey Complex Figure Test: Delayed Recall, and Rey Complex Figure Test: Recognition are showed significant improvement. In addition, there was a significant im-provement in CDR (sum of box) and K-MoCA scores. There was no statistically significant difference in K-IADL and K-NPI. Conclusion Computerized cognitive training programs have been effective in improving memory in patients with mild cognitive impairment. In order to verify the effectiveness of dementia prevention, a long-term study of a larger number is needed.The results of this preliminary study will help develop and apply cognitive training contents in the future.

Patients with neurocognitive disorder show behavioral psychological symptoms such as agitation, aggression, depression, and wandering, as well as cognitive decline, which puts a considerable burden on patients and their families. For the treatment of behavioral psychological symptoms, patient-centered, non-pharmacological treatment should be used as a first line approach. This paper describes non-pharmacological interventions tomanage and treat behavioral psychological symptoms in patients with neurocognitive disorder. In order to control behavioral psychological symptoms such as agitation, depression, apathy, insomnia, and wandering, it is important to identify and evaluate factors such as environmental changes and drugs, and then solve such problems. Non-pharmacological interventions include reassurance, encourage, distraction, and environmental change. It is necessary to understand behavior from a patient's point of view and to approach the patient's needs and abilities appropriately. Reminiscence therapy, music therapy, aroma therapy, multisensory stimulation therapy, exercise therapy, light therapy, massage therapy, cognitive intervention therapy, and pet therapy are used as non-pharmacological interventions, and these approaches are known to improve symptoms such as depression, apathy, agitation, aggression, anxiety, wandering, and insomnia. However, the quality of the evidence base for non-pharmacological approaches is generally lower than for pharmacological treatments. Therefore, more extensive and accurate effectiveness verification studies are needed in the future.

The morphological change of pelvis in obstetrical part is very important for the partruition and its analysis is also critical in anthropological part studying the morphological differences between male and female pelvises by age. The measurement of dry bones is currently used for analyzing the changes, but this method has some difficulties including in sampling the dry bones. To solve this problem and analyze the morphological changes of pelvis accurately, we used the X -ray photographic films showing whole pelvis, vertebrae, and femur. The whole pelvis and proximal femur's X -ray photographies were taken from 506 individuals who were over 20 - year old age, non -pregnant, and normal posture Korean females. And the several values from the photographies were measured for analysis including maximum pelvic breadth (MPB), sacral breadth (SB), transverse diameter of pelvic inlet (TD), distance between ischial spines (ISD), distance between femoral heads (IHD), and distance between greater trochanters of femur (ITD). The results revealed that the TD values were highly correlated to other pelvic items, but not to ages, suggesting that TD is not anatomically changed to the correlation of parturition times. Also, the IHD values were highly related to the ITD and TD values, but the ISD values had relatively low correlations with MPB and ITD values. Depending on ages, the MPB values were gradually increased, while the ITD values were gradually decreased, indicating that these morphological changes of pelvis by ages are reflecting an aging process.

PURPOSE: To investigate the effects of brimonidine, an alpha-2-adrenergic agonist, on barrier function in ARPE-19 cells by measuring transepithelial resistance (TER). METHODS: ARPE-19 cells were cultured into a confluent monolayer on a microporous filter. Brimonidine was added to the apical medium, and the barrier function of the cells was evaluated by measuring TER. A subset of cells was treated under hypoxic conditions, and the TER changes observed upon administration of brimonidine were compared to those observed in cells in normoxic conditions. RESULTS: The ARPE cell membrane reached a peak resistance of 29.1+/-7.97 Omega cm2 after four weeks of culture. The TER of the cells treated under normoxic conditions increased with brimonidine treatment; however, the TER of the cells treated under hypoxic conditions did not change following the administration of brimonidine. CONCLUSIONS: Barrier function in ARPE-19 cells increased with brimonidine treatment. Understanding the exact mechanism of this barrier function change requires further investigation.

Objectives: ：The purpose of this study is to compare bleeding tendency of selective serotonin reuptake inhibitor (SSRI) and serotonin norepinephrine reuptake inhibitors (SNRI) using platelet function analyzer (PFA-100) in patients with major depressive disorder. Methods: ：This study is a prospective open-label study conducted by a single institution. A total of 41 subjects diagnosed with major depressive disorder under the DSM-5 diagnostic criteria participated in this study.The subjects were classified into SSRI (escitalopram) groups and SNRI (duloxetine) groups, respectively, according to random assignments. The closure time (CT) was measured using a platelet function analyzer (PFA-100) before each antidepressant was administered and after 6 weeks. Paired-sample t-test was conducted within each group to determine whether a specific antidepressant had an effect on closure time. In order to confirm the rela-tive change in platelet function between the two groups, an independent sample t-test was conducted to compare and analyze the change in closure time between the two groups. Results: ：There was no significant changes in closure time (CEPI-CT, CADP-CT) before and 6 weeks after drug administration in the SSRI and SNRI groups, and there was no difference in the amount of changes in closure time between the two groups. Conclusions ：Our results showed no difference in bleeding tendency between SSRI and SNRI. This study suggests that further large-scale studies on bleeding tendency for various antidepressants are needed in the future.

Objectives: ：The aim of this study was to compare activities of daily living (ADLs) according to degenerative changes in brain [i.e., medial temporal lobe atrophy (MTA), white matter hyperintensities] and to examine the association between neurocognitive functions and ADLs in Korean patients with dementia due to Alzheimer's disease (AD) and mild cognitive impairment (MCI). Methods: ：Participants were 111 elderly subjects diagnosed with AD or MCI in this cross-sectional study. MTA in brain MRI was rated with standardized visual rating scales (Scheltens scale) and the subjects were divided into two groups according to Scheltens scale. ADLs was evaluated with the Korean version of Blessed Dementia Scale-Activity of daily living (BDS-ADL). Neurocognitive function was evaluated with the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment packet (CERAD-K). Independent ttest was performed to compare ADLs with the degree of MTA. Pearson correlation and hierarchical multiple regression analyses were performed to analyze the relationship between ADLs and neurocognitive functions. Results: ：The group with high severity of the MTA showed significantly higher BDS-ADL scores (p<0.05). The BDS-ADL score showed the strongest correlation with the word list recognition test among sub-items of the CERAD-K test (r=-0.568). Findings from the hierarchical multiple regression analysis revealed that the scores of MMSE-K and word list recognition test were factors that predict ADLs (F=44.611, p<0.001). Conclusions ：ADLs of AD and MCI patients had significant association with MTA. Our study, which identi-fies factors correlated with ADLs can provide useful information in clinical settings. Further evaluation is need-ed to confirm the association between certain brain structures and ADLs.

Objectives: ：The aim of this study was to compare the effect of Selective Serotonin Reuptake Inhibitor (SSRI) and Serotonin Norepinephrine Reuptake Inhibitor (SNRI) for mood symptoms, pain, and somatic symptoms in elderly depression patients with pain and somatic symptoms. Methods: ：This study is a prospective open-label study conducted by a single institution. A total of 43 subjects diagnosed with major depressive disorder under the DSM-5 diagnostic criteria participated in this study (average age: 72.53, 58.1% women). The subjects were classified as SSRI and SNRI groups. Depressive symptoms, pain, and somatic symptoms were evaluated by Korean version of the Hamilton Depression Rating Scale (K-HDRS), visual analogue scale (VAS) and Patient Health Questionnare-15 (PHQ-15) respectively at baseline and six weeks later. Two-way repeated-measure ANOVA was performed to analyze changes in the KHDRS, VAS, and PHQ-15 scores. Results: ：In the SSRI and SNRI groups, K-HDRS, VAS, and PHQ-15 all showed significant improvement after 6 weeks compared to each baseline values. There were no differences in therapeutic effect between the two groups. Conclusions ：We found that SSRI and SNRI both improved somatic symptoms and pain in elderly depression patients. The results of this study are thought to help select antidepressants when administering medication to elderly depression patients who complain pain and somatic symptoms. Further research is needed on the longterm effects of the SSRI and SNRI.

OBJECTIVE: Body composition is measured using bioelectrical impedance analysis (BIA), and correlation between the result of BIA and cognitive function is analyzed. METHODS: A total of 118 elderly (46 male, 72 female) were recruited. They were divided into three groups; normal (n=33), mild cognitive impairment (n=42), and Alzheimer's dementia (n=43) according to the diagnostic criteria. Skeletal muscle mass, body fat mass, and fat-free mass were measured using a BIA device, and were converted to the ratio of body weight. All participants underwent Korean version of Mini-Mental State Examination (MMSE-K). RESULTS: In pearson correlation analysis, skeletal muscle percentage (SMP) and fat-free mass percentage (FFMP) were positively correlated with MMSE-K score (r=0.309, p=0.001; r=0.245, p=0.008), and body fat percentage was negatively correlated (r=−0.258, p=0.005). In multiple regression analysis, SMP (β=2.012, t=4.457, p < 0.001) and FFMP (β=−1.733, t=−3.838, p < 0.001) were selected as the best predictors of changes in MMSE-K score (R2=0.198). CONCLUSION: Reduced skeletal muscle and increased body fat correlate with decreased cognitive function, suggesting the need for prevention of frailty and early diagnosis of cognitive impairment.
