Objectives: Hypermenorrhea is one of the most common symptom in gynecologic department. Organic causes of hypermenorrhea are endometrial polyp, chronic cervicitis, endometrial dysplasia and endometrial cancer. To find the exact cause of hypermenorrhea and rule out the organic uterine disorder in the patient who considered hypermenorrhea, hysteroscopic examination and endometrial biopsy were performed. Methods: Study group were 125 patients, who received hysteroscopic endometrial biopsy from 2. 2001 to 2. 2005 with hypermenorrhea, negative in urine pregnancy test, normal in cervix cytology, and without organic lesion causing hypermenorrhea in pelvic exam and ultrasonography. Age, Parity and hysteroscopic biopsy result were analyzed retrospectively. Results: Mean age of the study group was 34 and mean parity was 1.5. When final hysteroscopic biopsy histology were analysed, Proliferative and secretory phase were most common (64.8%), folloewed by simple hyperplasia (20.8%), endometrial polyp (10.4%), chronic cervicitis (2.4%), endometrial dysplasia and endometrial malignancy (0.8%). Of 125 patients, who considered primary hypermenorrhea, 107 (85.6%) Patients were proved true primary hypermeorrhea on hysteroscopic biopsy. The others had abnormal findings (14.4%). Conclusions: When patients visited the hospital with hypermenorrhea, doctors should be suspicious of endometrial organic disease and treat the patients with exact diagnosis, In these patients, hysteroscopic examination and biopsy were very useful and safe method to determine exact diagnosis and treatment plan.

〈乐原〉和〈琴原〉是赵孟頫文集《松雪斋集》里收录的乐论,以前在我们国家只知道赵孟頫是著名的书画家,但关于他对乐论的认识我们从来没有做过研究,而〈乐原〉和〈琴原〉则是他代表性的乐论。他以古代的律学,琴学,礼学为基础,揭示了当时具有社会责任的儒者以及他们的社会意识。本研究首先注解〈乐原〉和〈琴原〉内容,利用音律表对乐论进行说明,在此基础上,赵孟頫通过乐论揭示了儒者的意识。结果我们发现,赵孟頫的意识是孔子主张的乐的‘教化性’和‘效用性’为基础的,特别是〈乐原〉里,关于“八清”的回復主张的观点正是赵孟頫復古意识的说明,所以通过研究〈乐原〉和〈琴原〉,理解华夏民族的文化精神,继承发扬礼乐思想研究它对后代的影响。

Among the default risks, systemic risk is of the biggest concern over the safety and efficiency of the payment and settlement system. When homogeneous financial institutions are linked with each other through the credit chain, a gridlock takes place as equilibrium in the payment and settlement system. A heterogeneous participant in the system could, however, have incentive to fulfill the obligation when otherwise homogenous participants strategically default. That is, fulfillment of obligation turns out to be a Nash equilibrium strategy for the heterogeneous participant whose level of investment return differs from those of remaining participants. The larger the benefit is, the stronger incentive a financial institution has to keep the system working properly. The current paper sheds new light on the effect of heterogeneous financial institutions on the robustness of payment and settlement system under the general equilibrium setup.
