Background/Aims: The purposes of this study were to describe restrictions in instrumental activities of daily living (IADL) in mild cognitive impairment (MCI) and to assess different patterns of IADL in each MCI subtype. Methods: A total of 566 participants, those not cognitively impaired (NCI; n = 311) and MCI patients (n = 255), 60–94 years old (71.25 ± 6.00), were examined. Neuropsychological tests were administered to participants, and each MCI patient was classified into one of four subtypes. They completed the Barthel ADL and Seoul-IADL (S-IADL) for ADL measures. Results: There was a significant difference between NCI and MCI in terms of total S-IADL scores. ANOVA and a post hoc Dunnett analysis revealed that MCI patients performed significantly worse on four out of a total 15 items (i.e. telephone, transportation, finances and household appliances). ANCOVA showed a significant difference in S-IADL-MCI (4 of 15 items) between NCI and amnestic MCI-multiple domains after adjusting for age, gender, education and Geriatric Depression Scale (F = 4.257, d.f. = 1,556, p = 0.002). Conclusion: These findings suggest that scorings of specific IADL items are different in MCI subjects, and these items can possibly help in the identification of MCI subtypes, especially amnestic MCI-multiple domains.

This study was conducted to describe the relationship of past trauma and current stress on the mental health of North Korean (NK) defectors living in South Korea 7 years after a baseline assessment. Of the 200 who participated in the initial study, 106 participated in follow-up. Previous data regarding past traumatic events experienced in North Korea and during defection, past posttraumatic stress disorder (PTSD), and their current stress levels were correlated with the participants' current mental health status including depression, anxiety, and PTSD. The rate of PTSD in the sample and the scores on the PTSD symptom scale decreased significantly from the baseline. The participants' current mental health was negatively related to previous traumatic experiences in North Korea and past symptoms of PTSD, but unrelated to previous trauma experienced during defection. In addition, although current mental health was negatively related to only current culture-related stress, it was unrelated to the level of current ordinary life stress. The results of this study suggest that PTSD symptoms decreased during the 7 years between assessments, and that current culture-related stress is the most important variable related to the mental health of NK defectors living in South Korea.

This study examined jury trials conducted during the first three years since the introduction of a new jury system in South Korea. Case information from all jury trials held during the time was collected and empirically analyzed with a focus on judge‐jury agreement. The statistical analyses were guided by previous studies (Eisenberg et al. ; Spencer ). Results indicated that judges and juries agreed on the verdict 91.4 percent of the time (70.3 percent for conviction and 21.1 percent for acquittal). When they disagreed, juries had a greater tendency to acquit than did judges (7.4 percent and 1.2 percent, respectively). Neither evidentiary strength nor complexity had any systematic impact on agreement rates. Judges were more likely than juries to convict across all levels of evidentiary strength. The accuracy and error rates of jury verdicts were assessed by estimates of conditional probability.
