The purpose of this is made an examination of phosphorus loading model for eutrophication response in the Yongsan lake. For the model, we measured the total amount of nutrients derived from the Yongsan river watershed, inflow rate to the Yongsan lake, water quality, and water budget from January to December in 1999. The total amount of precipitation in the Yongsan river watershed was 4,951.7$\times$10$^{6}$ ㎥/y and inflow amount was 2,569.7$\times$10$^{6}$ ㎥/y, therefore the outflow rate of the Yongsan river watershed was 51.9%. The develop loading of total nitrogen was 86,928.1kg/d and that of total phosphorus was 22,007.6kg/d at the Yongsan river watershed, But, as the inflow loading of total nitrogen was 33,962kg/d and the inflow loading of total phosphorus was 2,218kg/d to the Yongsan lake. so each infolw rate was 39.0% and 10.1%. The hydraulic residence time was 34days, total phosphorus loading [L(P)] on the surface area was 23.398g/㎥/y, the hydraulic load( $Q_{s}$) of inflow water was 74.269m/y, the reserve rate of phosphorus in the lake was 0.359, and the settinh velocity of phosphorus was 0.114m/d at the Yongsan lake. Mathematical model of phosphorus loading to estimate the responses of eutrophication at the Yongsan lake is [ $P_{j}$] = 0.838 [L(P)/Q.(1+√ $T_{w}$)$^{-1}$ ] . ] . .

The ongoing Yongsan Park development project began in 1988 with the development of a utilization plan for the US Army base in Yongsan after the Army relocation. This study aimed to draw implications for the Yongsan Park project by focusing on Yongsan Family Park. Among the public records of Yongsan Park and Yongsan Family Park transferred to the Seoul Metropolitan Archives, 53 major records were analyzed. The results are as follows. First, Yongsan Family Park, built on the site of the US Army golf course in 1992, was considered a part of the Yongsan Park plan and holds status as the first phase of the Yongsan Park project. Second, despite its status, Yongsan Family Park opened as a temporary park occupied by urban facilities. A design and detailed roadmap of the development process is necessary to make Yongsan Park more resilient. Third, organizing and systematizing public records is necessary because lessons learned through past park development processes can be applied to the current project. This study is meaningful since it uncovered important issues of urban planning discussed in the process of Yongsan Family Park development through a complete analysis of public records, examined the linkage between Yongsan Family Park, which was not known until now, and the ongoing Yongsan Park project, and reaffirmed the importance of park archiving for long-term development projects.

This study estimated economic value and benefits of Yongsan National Park, which will be constructed by financial investment of the government and objectively estimated the real value of it by understanding the value of the park from a user's view of the park. For this, the value of Yongsan National Park is divided into using value such as carbon reduction and the function of relieving urban heat island as an environmental material and non-using value based on willingness to pay of the public according to the construction of the park. As a result of the analysis, it was found out that the using value of Yongsan National Park would reach 130 million won up to maximum level of 450 million won per year, and the non-using value was analyzed to be worthy of 2,344 won per capita every month. Besides, economic ripple effect that can be expected in the process of the park construction project was analyzed to be a national policy that creates effect on production inducement of 2.6 trillion won and value added of 809.6 billion won and new jobs for 25,620 persons. Considering the value of Yongsan National Park and the effect of the project based on the result of this study, it was found that it could sufficiently secure the validity of implementing the project compared to the financial investment by the government. Therefore, it must be emphasized that diffusion strategy is necessary for national understanding and for a nation to make it understood its appropriateness widely in respect to the construction of Yongsan National Park for the successful construction of Yongsan National Park and to raise its using value in the future.

Every one hopes for the strong or healthy families and happy society, The Healthy Families Act legislated on February 9, 2004, and three centers were appointed to perform as a model, before the law has been in force from January 1, 2005. The major services or programs at the Center performed last year were as follows; educational programs, counseling for prevention of family problems, and cultural events for strengthening the family functions. This study presented the general situations of Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families last year, evaluated the product of cultural events or programs, and proposed better ideas for managing cultural services or programs. In 'the division of Home Culture', the community networks were established, and diverse events or programs provided drew high satisfaction among attendants. In the future, some services or programs at Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families hoped to be helpful and made a basis for activating services or programs for other centers.

In order to establish water quality management planning in some watershed, water quality of the future of the watershed should be predicted first. The Yongsan river various pollutant sources ; sewage, industry, livestock, farming and so on. And pollutants from these sources are likely to increase even though a number of publicly owned treatment works(POTWs) are founded. Therefore, it is estimated that water quality if the river would be even worse than now in near future. In this study, water quality of the future(2001, 2006) on the Yongsan river was simulated with QUAL2E model. Concentration of three water quality parameters(BOD, T-N, T-P) was predicted according to dry season, low flow season, average flow season of the river with and without POTWs. The results of this study showed the significant contrast in concentration between with and without POTWs, specially in terms of T-N and T-P. Therefore, POTWs must be founded around the Yongsan river and more advanced treatment should be considered. And because these parameters are mostly affected by polluants from upper watershed, including Kwangiudcheon, water quality management planning on the Yongsan river might be focused on this area.

Remote cerebellar hemorrhage (RCH) is rare but potentially lethal as a complication of spinal surgery. We recently experienced a case of RCH in a 61-year-old man who showed mental deterioration after lumbar spinal surgery. There was dural tearing with subsequent cerebrospinal fluid (CSF) loss during the surgery. Brain computed tomography scan revealed cerebellar hemorrhage, 3rd and 4th ventricular hemorrhage and pneumocephalus. He underwent suboccipital craniectomy and hematoma removal. The most important pathomechanism leading to RCH after spinal surgery has been known to be venous bleeding due to caudal sagging of cerebellum by rapid leak of large amount of CSF which seems to be related with this case. Dural repair and minimizing CSF loss after intraoperative dural tearing would be helpful to prevent postoperative RCH.

Capillary hemangiomas are common soft tissue tumors on the skin or mucosa of the head and neck in the early childhood, but very rare in the neuraxis. A 47-year-old man presented with one month history of back pain on the lower thoracic area, radiating pain to both legs, and hypesthesia below 17 dermatome. Thoracic spine MRI showed $1{\times}1.3{\times}1.5\;cm$, well-defined intradural mass at T6-7 disc space level, which showed isointensity to spinal cord on T1, heterogeneous isointensity on T2-weighted images, and homogeneous strong enhancement. The patient underwent T6-7 total laminotomy, complete tumor removal and laminoplasty. Histologically, the mass showed a capsulated nodular lesion composed of capillary-sized vascular channels, which were tightly packed into nodules separated by fibrous septa. These features were consistent with capillary hemangioma.

We report the case of a 64-year-old man with dural arteriovenous fistula (DAVF) at right jugular foramen, presented as subarachnoid and intraventricular hemorrhage. The malformation was fed by only the neuromeningeal trunk of the right ascending pharyngeal artery and drained into the right lateral medullary veins craniopetally. Complete embolization was attained by selective transarterial glue injection, but patient showed lower cranial neuropathies. A 3-month follow-up angiogram still showed persistent fistula occlusion. Transarterial glue embolization is a feasible method, only if a transvenous access is not possible in case of single channel fistula.
