Objective: This study was performed to assess bacterial distribution concerned in sanitation management of public lavatory in Seoul. Methods: In this research, bacteriological investigation on public lavatory was accomplished for bidet water, bidet nozzle, washbowl and lavatory stool in the 50 public facilities such as public institutions, subway stations, cinema, department stores, large-scale buildings and hospitals amount to 374 specimens. Results: The geometric mean of colony forming unit(CFU) in total aerobic colony count were analyzed as follows; $5.2{\times}10^2/100cm^2$ on lavatory stool, $7.2{\times}10^3/ea$ on bidet nozzle, $7.8{\times}10^3/ea$ on center ring of washbowl, $1.4{\times}10/mL$ in bidet water (ml) and 7.0/ea on doorknob. Opportunistically pathogenic germs such as Staphylococcus aureus, Escherichia coli, Enterobacter cloacae, Pseudomonas aeruginosa were isolated in 3.7%, 5.9%, 3.2% and 1.9% of total specimens, respectively. Conclusion: The result of this study shows that there were some facilities where the pathogenic germs were detected to may cause urological infection. And the CFU of general bacteria as the representative indicator of disinfection and lavatory cleaning were high enough to imply the improvement of sanitation management of public lavatories should be contrived.

The purpose of this study was to investigate the distribution of microorganisms and the degree of contamination in the air of the dental clinics and to offer basic data as to the contamination of medical equipment and the prevention of the clinics. With this in mind, the researcher gathered air samples from the waiting rooms and medical offices of nine dental clinics in the city of J, South Korea with the use of a method of natural inattention and an air sampler and cultivated the samples on the plain table and drew from it bacteria falling and separated and sorted out the colony with the help of ATB and detected the distribution of the germs. The results are following, The number of bacteria falling in the air of the dental clinics was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The number of bacteria falling in the air of the medical offices was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The survey on the detection of staph. aureus reveals that all the dental clinics with the exception of B dental clinic proving to be positive had non-pathogenic staphylococci detected. The survey on the detection of pathogenic gram negative bacilli indicates that all the dental clinics but one were none detected. The survey on the distribution of germs shows that germs in 7 out of 9 dental clinics were none detected, and that they in four out of 9 waiting rooms were none detected. All the germs detected in the others were mostly non-pathogenic. The study shows that all the subject dental clinics but one were hygienically controlled and that there was a difference in accordance with cleaning and sterilization. This means that dental clinics should be equipped with systematic programs for cleaning and sterilization designed to prevent infection.

Recently, biological weapons (BWs) prepared with pathogenic microorganisms, toxins and biological vectors have been used maliciously for biological warfare, bioterrorism and/or agroterrorism by hostile countries and terrorists. In this review, historical background of disease and malicious use of BWs pathogenicity of microorganisms, advanced methodology involved in laboratory diagnosis, and prevention and control of anthrax (Bacillus anthracis), plague (Yersinia pseudotuberculosis subs. pestis), glanders (Burkholderia mallei), and smallpox (Variola virus) which have been abused for biological warfare or bioterrorism were discussed. In addition, the pathogenicity of microorganisms and the methodology needed to diagnose and control 6 diseases identified by WHO/CDC, ie., smallpox, inhalation anthrax, pneumonic plague, botulism, tularemia, and hemorrhagic fevers that would wreak havoc if terrorists successfully disseminated the germs by air were described.

Impulse of ki refers to palpitation around the navel, it is mostly caused by impairment of yang due to erroneous sweating, deficiency of the spleen yang. Behcet's syndrome caused by prolonged damp-heat and pathogenic germs. Its symptoms are characterized by conjunctival congestion, blue canthus and ulceration of the oral cavity, restlessness all the time, etc. It is advisable to follow the therapeutic principles of clearing away heat and drying damp, detoxicating and sterilizing. Lily disease is one of the emotional disease. It caused by yin deficiency of the heart and lung, found in mental depression or convalescence after a critical disease. Its symptoms are characterized by restlessness, reticence, insomnia, failure to walk, poor appetite, a subjective hot or cold, bitter taste and dark urine. It is advisable to follow the therapeutic principle of nourishing yin to clear away heat. Cholera refers to the disease marked by sudden severe vomiting and diarrhea, and colic of the heart and the abdomen. It is mostly caused by deficiency of the ki in the middle-energizer, emotional stress, etc. It is characterized by such symptoms as sudden severe vomiting and diarrhea, restlessness, etc. It is advisable to follow the therapeutic principles of warming yang and removing toxic substances, and strengthening the spleen and stomach. Heat invasion of blood chamber due to affection of the exterior pathogens, pathogenic heat invading the blood in deficiency and fighting with the blood. Its symptoms are marked by fever, feeling of the fullness, etc. There are deficiency of blood, hot blood and stasis of blood. The different therapeutic treatment should be taken according to different types thereof.
