Due to the advances in the computer network and communication technology, computers are populaurizing in every sector in our society and these computers are connected by networks such as the Internet. Although this environment facilitates people to share information and resources, it also provides hacker with posibility to steal valuable information and damage computer systems and networks belonging to other people. To remedy this problem, we develop many tools which capture network packets and analyze and/store them, but the problem with these tools is that it is difficult to add or change their functionality and connect them to other security tools, In this paper we explain a general purpose packet capturing tool which not only captures and analyzes/blocks packets. but can be connected to other security tools easily. We explain the architecture and the packet filtering specification language for this tool.

A case of a female subject with a unilateral vaginal ectopic ureter associated with a single system, ipsilateral hypoplastic pelvic kidney and bicornuate uterus is reported. Although there are many reports of concomitant urinary and reproductive system malformations, a review of the literature shows these unique associations in the same patient to be extremely rare. This malformation is not limited to any combination of abnormal development of the mesonephric(wolffian) and paramesonephric(mllerian) ducts in the development of the urogenital system. Embryological aspects as well as clinical presentation, diagndstic approach and treatment applicable to this case are discussed.

<P>Since their ubiquity in the ocean and marine organisms was first revealed, global concern about microplastics has grown considerably. The North Pacific Ocean and the adjacent marginal seas have high levels of microplastic contamination compared with the global average. This special issue on microplastics was organized by the North Pacific Marine Science Organization to share information on microplastic pollution in the North Pacific region. The special issue highlights high levels of contamination in the North Pacific both on shorelines and at the sea surface. Particularly high levels of contamination were reported on the western and southern coasts of Korea. Sources, including sewage discharge, aquaculture, and shipyards, were implicated. With the direction and energy of surface winds and currents have an important influence on shoreline patterns of distribution. The special issue also demonstrates potential for ingestion of microplastic by small planktonic organisms at the base of the food chain. A wide range of chemicals are associated with plastic debris and concerns are expressed about the potential for these chemicals to transfer to biota upon ingestion. As an introduction to the topic, this paper provides a brief background on microplastic contamination, highlights some key research gaps, and summarizes findings from the articles published in this issue.</P>
Application of a Sediment Quality Index to the Masan Bay, Korea
Shim, Won-Joon,Hong, Sang-Hee Korea Institute of Ocean ScienceTechnology 2007 Ocean and Polar Research Vol.29 No.4
A sediment quality index (SQI) and a mean sediment quality guideline quotient (M-SQGQ) were applied for the assessment of sediment quality in Masan Bay, Korea where metals and organic pollutants are of concern. The SQI was calculated by two functions, 'scope' (the number of variables that do not meet guideline objective) and 'amplitude' (the magnitude by which variables exceed guideline objective), with six different sediment quality guideline values from Canada, USA and Australia/New Zealand. Categorization of sediment quality was on the basis of SQI scores. The SQI values were compared with six guideline values applied as well as with the M-SQGQs. The SQI values were severely influenced by a few variables of high exceedance in the degree of non-compliance. The SQI values were very dependent on both the numbers and values of guideline variables used in index caluculation. Nevertheless, the SQI could provide integrated and simplified information from a large number of chemical data set. It is required to further evaluate protocols and guideline applied for deriving SQI and to compare it with field based sediment toxicity test and ecosystem integrity.
P246 : A study of ultrasonographic findings on the locations of subgaleal lipomas
( Joon Won Huh ),( Young In Jeong ),( Geon Kim ),( Hyun Chul Shim ),( Mihn Sook Jue ),( Eun Jung Kim ),( Hyang Joon Park ) 대한피부과학회 2013 대한피부과학회 학술발표대회집 Vol.65 No.2
Background: Subgaleal lipoma is a rare benign lipomatous neoplasm appearing between the galea and the periosteum of the frontal bone. Preoperative recognition of the tumor location is important due to surgical complications. Ultrasonography is an useful diagnostic tool to detect the depth of tumor non-invasively before surgery. However, some findings doesn`t correspond with the actual locations of tumors, especially in the forehead. Objectives: To evaluate the accuracy of preoperative ultrasonographic findings for subgaleal lipomas. Methods: The study included 10 patients with soft tissue tumor in the forehead who underwent preoperative ultrasonography and diagnosed as subgaleal lipoma after surgery from July 2009 to June 2013. We compared the diagnostic locations of tumors by ultrasonography with the actual locations, and evaluated the sensitivity of preoperative ultrasonography for the location of deep lipomas. Results: In only 3 of 10 cases, locations of the tumors were above the frontal bone on ultrasonographic examination. However, all of them were revealed as subgaleal lipomas intraoperatively. The sensitivity for detection of subgaleal lipoma location on ultrasonography was 30%. Conclusion: Since the accuracy of ultrasonography of locations of deep lipomas is not so high as expected, we may consider other diagnostic methods to reduce intra-or postoperative complications such as facial nerve damage.
