The 21st century is characterized as an era of information. Information and knowledge will be the most important force to shift our society toward another stage of development. This study analyzes two aspects of information network systems and suggests some policies and strategies for intelligent usage of the systems. Information network systems make knowledge more worthwhile through modification and circulation in public and business areas. INTERNET is a perfect example. On the other hand, information network systems may give people and business firms harmful consequences through abuse of knowledge. In this context, an internet security model including some policy suggestions is described in this article. First, governments and firms should establish legal apparatus to protect valuable information. Second, governments and firms should develop technical means to protect information and knowledge from hackers. Third, network systems should be invented to preclude physical interventions from outside. Fourth, network managers should be educated and oriented with security consciousness. Fifth, valuable information and knowledge should be administered by extraordinary practices and with special attention. Finally, it is important to decide which information and knowledge should be protected and allowed to use in terms of security costs. This managerial decision is important for the efficient and economic management of information network systems.

Spontaneous renal rupture is a rare condition. Renal rupture most often occurs as a result of traumatic injury, a rare entity of obstructive uropathy with stones, and spontaneous causes such as malignancy. We report on a rare case of renal rupture caused by a ureter stone measuring 5 mm in size with acute pyelonephritis (APN) in a patient with renal papillary necrosis (RPN). The patient, who suffers from attacks of gouty arthritis, frequently used analgesic for pain relief. The patient was treated with temporary percutaneous drainage and antibiotics. This case demonstrates that RPN with APN can induce renal rupture even when ureter stones are small. Thus, consideration of all medical problems is important when deciding on treatment of patients with ureter stones.

Purpose: Escherichia coli is the most frequent pathogenic agent of urinary tract infection, causing a wide spectrum of clinical syndromes from asymptomatic cystitis to pyelonephritis or sepsis. We studied the changes of antibiotic sensitivity to E.coli of urinary tract infection for alternative years in order to give some useful informations about the choice of adequate drug in the treatment of UTI. causing E.coli. Materials and Methods: We retrospectively reviewed the hospital charts of 185 cases with causative E.coli of urinary tract infection, who were admitted to or visited the hospital and had more than 10^(5)cfu/ml on urine culture in 1998, 2000, 2001 and 2002. Results: In E.coli isolates, resistance to six antibiotics changed significantly: ampicillin(57.14%, 84.38%, 85.07%, 55.10%), amoxacillin+clavulate(44.44%, 16,42%, 4.17%), ticacillin(84.62%, 75%, 86.67%, 51.14%), ticacillin-clavulate (0%, 51.35%, 11.94%, 4.08%), and trimethoprim(0%, 75%, 59.62%, 28.57%). Conclusion: Using ampicillin, trimethoprim/sulfamethoxazole as the first choice in the treatment of UTI should be reconsidered in Jeju.
