2008년 글로벌 금융위기 이후 둔화된 경기를 회복시키기 위해서 한국은행은 통화완화정책을 장기간 시행하고 있지만 경기는 금융위기 이전으로 회복되지 못하고 있다. 지속적인 저금리로 인한 잠재적인 문제점은 통화정책의 시행이 유의한 효과를 실물경제에 줄 수 있을지 의문시된다는 점이다. 본 연구에서는 금융위기 전과 후에 은행대출 경로를 통한 통화정책의 영향이 변화가 있었는지 그리고 저금리 수준에서 통화정책의 효과가 유효 하였는지를 분석하였다. 본 연구에서는 먼저 시변계수(time varying parameter) VAR 모형을 이용하여 시간이 흐름에 따라 통화정책에 대한 은행대출 반응이 변화되었는지 살펴보았다. 또한 동학적 패널모형(dynamic panel model)을 이용하여 금융위기 이전과 이후를 기간별로 나누어 통화정책에 대한 은행대출의 변화를 분석하였다. 분석 결과 금융위기 이후 장기적으로 총대출과 가계대출 증가율에 대한 통화정책의 영향은 감소되었고 단기적인 저금리 구간에서 기업대출 증가율에 대한 통화정책의 효과는 약화되는 것으로 조사되었다. Since the Global Financial Crisis of 2008, the Bank of Korea have taken easing monetary policy to boost the sluggish economy. In spite of this measure, the economy has been still weak. A latent problem caused by persistently low interest rate is that the monetary policy may have sapped a significant effect on the real economy. This paper analyses the monetary policy effectiveness at very low interest rates through bank lending channel before and after the Global Financial Crisis. In this paper, we started by estimating a time varying parameter VAR model to explore lending changes in long-term periods. And using a general dynamic panel model for two periods before and after the crisis, we estimated the growth rate of loans for monetary policy. Our analysis suggests that the impact of monetary policy on the growth rate of total and household loans would be significantly weak after post-crisis in the long-term periods. In another finding, the monetary policy is less likely to affect the growth rate of corporate loans at very low rates in terms of the short-term periods.

Objective: To investigate the prevalence, the distribution of deciduosis, and the relationship with endometriosis in fertile women during Cesarean delivery. Methods: In this study, pelvic tissues suspicious for ectopic deciduas were taken for biopsy during Cesarean section from 154 parturients of full term pregnancy from January 1990 to December 2003. And then those patients were followed up till April 2008. Results: Tissues from 94 parturients (94/154, 61%) were evaluated histopathologically, and ectopic decidua was observed in 70.2% (66/94). Ectopic sites were ovaries only (65/94, 69.1%), ovaries and uterine serosa (12/94, 12.8%), uterine serosa only (9/94, 9.6%), and pelvic serosa. Twenty seven (27/66, 40.9%) parturients had past history of diagnosis and treatments for endometriosis. We have tried to connect 39 (39/66, 59.1%) patients who had never been diagnosed for endometriosis but pathologically confirmed for deciduosis, and 18 patients were able to contact by phone. Twelve patients (12/18, 66.6%) showed no symptoms of endometriosis and had not received any treatments for endometriosis. Conclusion: We can conclude that most of incidental cases confirmed pathologically for deciduosis during pregnancy do not symptomatically progress. 목 적: 임신 능이 확인된 가임 여성에서 다능성 세포가 화생되거나 이전에 존재하던 골반 내 자궁내막증으로부터 발생하는 deciduosis의 발생빈도와 분포, 자궁내막증과의 관계를 알아보고자 하였다. 연구방법: 1990년 1월부터 2003년 12월까지 만삭임신에 이른 154명에서 제왕절개술시 의심되는 병변에서 조직검사를 시행하여 deciduosis의 빈도를 조사하였다. 결 과: 여러 다른 장기의 ectopic decidua는 94명 (94/154, 61%)에서 조사되었고, 이 중 66명 (66/94, 70.2%)에서 조직 검사상 deciduosis로 진단되었다. 발생빈도는 난소 (65/94, 69.1%), 난소와 자궁장막 (12/94, 12.8%), 자궁장막 (9/94, 9.6%), 복막 (2/94, 2.1%) 순이었다. 이 중 27예 (27/66, 40.9%)는 임신 전에 이미 자궁내막증으로 진단받아 다른 치료를 받았던 경력이 있던 여성이었고, 39예 (39/66, 59.1%)는 임신 전 자궁내막증으로 진단받지 않았던 경우였다. 임신 중에 deciduosis로 조직학적 확진을 받았지만 자궁내막증의 기왕력이 없었던 38명을 대상으로 2008년 4월 전화연락을 시도한 결과 통화 가능했던 18명 중 12명 (66.6%)이 다른 증상이 없어 특별한 치료 없이 지내고 있었다. 결 론: 본 연구에서 임신 시 조직학적으로 deciduosis가 확인된 대부분의 경우 자궁내막증으로의 진행은 없었다.

The problems of child support awards in divorce cases were analyzed in this study. This study investigated child support guideline of America, and analyzed income adequacy of Korean cases according to the income-to-needs ratios. Also rational child support guideline was proposed. The results of overall case analysis were as follows : 1) child support awards were too little to maintain children`s well-being, 2) there is no case whose award was determined the ratio of or share of non-custodial parent`s income, 3) a few cases showed different award even in the same cases, 4) there is no statement about the way to transfer child support. The results of income-to-needs ratio analysis indicated that even after transfer of child support, custodial parent`s income adequacy was lower, on the other hand non-custodial parent`s income adequacy was higher after divorce. So rational child support guideline, spreadsheet determining income-to-needs ratios for two households, could be proposed in order to distribute income evenly.

Objectives:The purpose of this study was to describe the status of mental activity participation in community-dwelling elderly and to evaluate the association between mental activity and cognitive function after adjustment for depression and anxiety. Methods:This study was based on the Suwon Project, which was a cohort comprising of nonrandom convenience samples of ethnic Koreans aged 60 years and above. All the subjects completed the study questionnaire including their demographic characteristics, current and past illnesses history, drug history, Korean version-Mini Mental State Examination (K-MMSE), Korean version of Short Form Geriatric Depression Scale (SGDS-K), Beck Anxiety Inventory (BAI). We checked how many hours per day are used for each items of 11 mental activities through the checklist. Results:Total time spent in 11 mental activities was 237.4±152.4 minutes per day. On multiple regression analysis, total time spent in 11 mental activities (MA-total), and time spent by watching television and reading book/newspaper showed statistically significant association with K-MMSE score after adjustment with age, sex, education, chronic medical illness, depression and anxiety. Conclusion:Our result suggested that mental activity may be associated with cognitive function in the elderly without cognitive impairment in the community after adjusting age, sex, education, chronic medical illness, depression and anxiety.
