[์˜๋ฌธ] Cognitive impairment and depression are the most common symptoms affecting the elderly physical and mental state. There have been studies that show such symptoms in mild cartes improve through psychosocial intervention, which further emphasize the importance of therapeutic intervention provided in the community. The purpose of this study is to investigate whether the psychosocial program at a geriatric day care has any therapeutic effect on the cognitive function and depressive symptoms in the elderly and if such effect can be maintained. The experiment group was composed of 37 elderly attending the day care at the mental health center located in Kwangju county, Kyonggi province. The control group was composed of 22 elderly who either refused intervention or who dropped out during the program. Cognitive function was assessed by tole Korean version of the Mini-Mental State Exam (MMSE-K), and depressive symptoms were assessed by the Short-form Geriatric Depression Scale (SGDS). The experiment group and the control group were compared by tole scores on each test which was administered before and after the program, and 10 weeks after discontinuation of program. In the experiment group, the scores acquired immediately after the program and at 10 weeks in follow-up were also compared. The results indicate that psychosocial intervention at a geriatric day care is significantly associated with the change in SGDS scores dependent on time but not significantly associated with the change in MMSE-K scores. In the experiment group whose follow-up assessment was possible, it was further shown that 43% of patients had increased SGDS scores 10 weeks after the program ended, indicating that depressive symptoms had worsened. This study shows that psychosocial therapeutic intervention in the geriatric day care improves depressive symptoms but not cognitive functions in the elderly. In addition, for a considerable percentage of subjects in the experiment group, the improvements in depressive symptoms were not sustained after the intervention was withdrawn. These findings suggest possible therapeutic effect of the psychosocial programs in the geriatric day care on elderly depression and propose a need for booster therapeutic intervention to maintain such effect.restrictio

    The aim of this study is to analyze the timing of earnings announcement as one of the important factors influencing investorsโ€™ decision-making in the stock market. Specifically, it focuses on the question whether the management makes strategic use of the timing of earnings disclosure depending on the type of the earnings information (Good/Bad) and whether the market reaction varies according to the different timing of the announcement. The sample data covers timely disclosure of annual earnings announcement from 2002-2006. This paper employs a sample of 1,912 firm-years. When compared to the previous period, earnings increase is categorized as โ€˜Good Newsโ€™ the opposite situation is categorized as โ€˜Bad News.โ€™ In brief, the results of the research are as follows: In the category of โ€˜Bad Newsโ€™, a clear tendency for the earnings to be announced after the market closed at 3:00 PM is revealed. This tendency appears even stronger, if the result of the present period is a loss. Also, different response for each case (Good/Bad) and its subcategory (announcement made before/after the market close) is analyzed using abnormal stock returns. In the case of โ€˜Bad Newsโ€™ with earnings announcement after the market close, abnormal returns exhibits a diminishing tendency which begins to show from one day after the earnings announcement. In this situation, the negative market reaction is more pronounced than in the case of โ€˜Bad Newsโ€™ with the announcement made before the market close. Furthermore, for โ€˜Bad Newsโ€™ released after trading hours, the market reaction is even more negative when cumulative abnormal returns of nine-day window (day -3 to day + 5) surrounding earnings announcement are used. In summary, the findings show that managers make strategic use of the timing of earnings announcement to reduce the negative market reaction to bad news. Nevertheless, despite their effort, the market starts to negatively react to bad news from the day following the earnings announcement. Overall, we believe this study sheds light on the research of disclosure timing by providing important implications to the market participants including the managers or policy makers. Moreover, we expect that various more detailed researches will be carried out in the future to investigate related issues.2
