Many enterprises have been putting importance of business administration internal management rather than the customers as having been unable to rapidly cope with the market change under the environment which we call $quot;the age of uncertainty$quot;. The wall between the hotel divisions in the traditional system has blocked the flow of information. As the system has been fatter, the greater amounts of indirect expenses have been paid. The concept of Business Process Reengineering by Michael Hammer is that $quot;the whole organization systems should be basically redesigned based on the business process for epochal increase in the key result of business administration.$quot; BPR is not the same as a renewal movement in existing systems or business methods. Hotels should consider the fundamental questions such as $quot;the reason for the existence of the system$quot;, $quot;the reason for the performance of each division$quot; and $quot;why such methods have been adopted at the time of business process$quot;. In other words, this study has been aimed to examine how BPR has been applied to hotels, human service enterprises in which the satisfaction of the customers is the good itself differ from other general enterprises of manufacture since BPR starts from $quot;Customers Value$quot;, what we call CS. Though Hotels have been realizing the importance of the thought based on the CS already, the application of BPR in general hotel business process has not yet been realized. As one of the methods of coping with such of the introduction of BPR concept should be seriously required to be applied as one of the innovation of hotel business administration.
Infrequent-Restriction-Site Polymerase Chain Reaction을 이용한 Legionella pneumophila의 분자역학적 분석

Background: The frequent outbreak of legionellosis makes it critical to identify infection sources for the prevention and blockade of transmission of the disease. Methods: Thirty-one strains of Legionella pneumophila isolated from the cooling towers of big buildings in Busan and Gyungsangnamdo Province areas, 12 strains of L. pneumophila from patients in Japan, and one type strain (L. pneumophila ATCC 33152) were used for molecular strain typing by using an infrequent-restriction-site polymerase chain reaction (IRS-PCR). Results: Each strain revealed to have 7-16 bands of 200-1000 bp size. All 44 strains showed band patterns different from each other, except two strains sharing 90% homology. Conclusion: The molecular typing of Legionella by IRS-PCR is an excellent and rapid method for discriminating strains; therefore, it should be useful in demonstrating the identity of possible outbreak strains.

Background: It is recommended that all rapidly growing mycobacteria (RGM) isolated from patients with mycobacteriosis are subjected to antimicrobial susceptibility testing. The current study was aimed to perform susceptibility test on clinical strains of RGM isolated from patients with mycobacteriosis and to determine the clinical significance of the isolates. Methods: For 17 patients with RGM infection from 2002 to 2006 at Ulsan University Hospital, medical records were reviewed retrospectively and anti-mycobacterial susceptibility test was performed for the clinical isolates by broth microdilution method. Results: Rates of susceptible strains of RGMs against individual drugs were as follows: amikacin 100%, cefoxitin 59%, ciprofloxacin 82%, clarithromycin 71%, doxycycline 18%, imipenem 91% (M. fortuitum), sulfamethoxazole 71%, and tobramycin 100% (M. chelonae). Ten of the 17 nontuberculous mycobacteria (NTM) patients had been treated with anti-tuberculosis drugs initially. Anti-tuberculosis drugs were continued in 3 patients and changed to other antimicrobial agents effective to NTM in 4 patients, all of whom were cured. Five of 7 NTM patients who had been treated with anti-NTM treatment were cured. All isolates from the patients treated with anti-NTM drugs were susceptible to at least one of the drugs administered. Conclusion: Clinical isolates of RGMs showed fully susceptible to amikacin, while highly resistant to doxycycline and variable to other drugs depending on the species.
