The purpose of this study was to evaluate microbiologically cooking utensils, equipment employees, and environment in 12 large Korean, Western, Chinese, and Japanese restaurant. Microbiological testing was conducted for pathogens including E. coli, Samolnella, L. monocytogenes, S. aureus, E. coli O157:H7, V. parahaemolyticus, B. cereus, and Y. enterocolitica as well as total plate count and coliforms. The results showed cooking water and drinking water in some Korean restaurants and drinking water in some Western and Japanese restaurants were unsatisfactory, especially, barley tea, which was cooled after being boiled, was unsatisfactory. Most cooking utensils such as knives, cutting boards, kitchen towels, tongs, and basket had total plate and coliforms count in excess of standards, and knives and cutting boards at some Chinese restaurant had E. coli. At some restaurant, S. aureus was found on some food worker's hands. Also, the total plate count of the air showed a high count around worktables, inside the refrigerator, and in the kitchen in most restaurants. These result suggest that sanitation needs improvement in the environments in these foodservice establishment.

This paper was concerned with the investigation on the species of fungi detected in indoor environments. Mycological survey on the wall of buildings and houses in Seoul was performed from December 26, 1983 to February 11, 1984. The collected fungi with the sterilized cotton rod were caltivated and isolated in the Potato-Detrose Agar medium with chloramphenicol. The fungi detected in hospital were Cladosporium sp., Penicillium sp., Alternaria sp., Chaetomium sp. and others. The fungi detected in household were Penicillium sp., Alternaria sp., Aspergillus sp., Cladosporium sp., Rhizopus sp., Trichoderma sp. and others. The kitchen of household was more contaminated by fungi than the living room and others. In hospital, it was much contaminated by the same species of the aboves on the wall of lobby and refectory. As the above results were recognized, the higher humidity and the more poor ventilation, the more species and amount of fungi were contaminated. Further studies on the identification of pathogenic fungi should be continued. The proper regulation for the hygienic maintenance of indoor environment in household, hospital and other public buildings should be recommended as well.

Der Begriff der Heilkundeausübung ist im positiven Recht in Korea nirgends festgelegt. Der wurde jedoch indirekt durch die Auslegung der Heilkundeausübung ohne Erlaubnis gemäß § 27 Abs. 1 des "Medizingesetzes" geregelt. In der Vergangenheit beschränkte der kOGH(the Supreme Court of Korea) die Heilkundeausübung auf die "Behandlung von Krankheiten und stellte fest, dass "medizinische und technische Maßnahmen, die keine pathologischen Symptome oder Funktionsdefizite im Körper voraussetzen, nicht zur Heilkundeausübung gehören." Danach änderte der kOGH seine Rechtsprechung auf "Vorbeugung oder Behandlung von Krankheiten durch Durchführung ärztlicher Untersuchungen, Optometrie, Verschreibung, Medikation oder chirurgischer Eingriffe auf der Grundlage von Erfahrung und Fähigkeiten, die auf medizinischem Fachwissen basieren, und anderer Gesundheitsfürsorge, definiert "medizinische Maßnahmen" als "eine Handlung, die eine gesundheitliche Gefahr darstellen kann, sofern diese nicht von einem Mediziner durchgeführt wird". Der Begriff der Heilkundeausübung in der Rechtsprechung ist einerseits zu abstrakt und kann eine Leerformel sein, andererseits kann seine Einschränkung eine Gefahr für die öffentliche Gesundheit erbringen. Daher besteht Bedarf an einem Kriterium, das dar derzeitige Begriff der Heilkundeausübung entsprechend dem gesetzgeberischen Ziel reduzieren kann, das Risiko für das Leben, den Körper oder die öffentliche Gesundheit von Menschen zu verhindern, das durch die Durchführung medizinischer Arbeiten durch nichtmedizinisches Personal entstehen kann. Um ein Kriterium vorzustellen, das das aktuelle Konzept der Heilkundeausübung reduzieren kann, werden in diesem Artikel das positive Recht, Theorien und Rechtsprechung zum Begriff der Heilkundeausübung in Deutschland untersucht und nach einer Alternative gesucht.

Questionnaires were distributed to Radiology departments at hospitals with 300 sickbeds throughout the Pohang region of North Gyeongsang Province concerning awareness and performance levels of infection control. The investigation included measurements of the pollution levels of imaging equipment and assistive apparatuses in order to prepare a plan for the activation of prevention and management of hospital infections. The survey was designed to question respondents in regards to personal data, infection management prevention education, and infection management guidelines. The ATP Public Heath Monitering System was used to measure seven items for pollution levels of imaging equipment and assistive apparatuses in the Radiology Department. Data was analysed using SPSS version 12.0 for paired t-test and Pearson coefficient with a statistically significant level of 0.05. The results of the survey showed a total awareness level of infection management prevention education averaged at $3.73{\pm}0.64$ and performance levels resulted at $3.39{\pm}0.83$ which were statistically significant (p = 0.01). Also the measurements of pollution levels for equipment with high patient contact showed a Pearson Coefficient of over 0.5 implying a focus on pathogenic bacterium. There was no statistical significance with the frequency of imaging (p < 0.05). Therefore for general hospitals with high patient contact, there is a need to supply analyzing equipment for real time monitoring and the implementation of disinfection management that uses a Ministry of Health and Welfare approved antiseptic solution twice every minute.

Microflora and contamination process of Saengshik products were investigated to ensure microbial safety of Saengshik. Food-borne pathogenic bacteria, such as Staphylococcus aureus, Bacillus cereus, and Clostridium perfringens detected mainly from grains were not removed by washing with tap water and freeze-drying. Contaminations of food-borne pathogenic bacteria occurred through raw material powder processed at other factories and during actual product manufacturing process, because detection rates of final products were higher than those of raw materials. Concentration of food-borne pathogenic bacteria increased with advancing of process after first pulverization. Dusts of powder and powder attached to machine were good media for air-borne microorganisms and caused to increase of food-borne pathogenic bacteria during process. Improvement of manufacturing process and sanitary control of machines arc necessary to ensure microbial safety of Saengshik.

This study was conducted to monitor and evaluate microbial contamination during manufacturing process in 6 red pepper powder factories. Red pepper powder samples were taken from manufacturing facilitates, working area and workers' hands to determine sanitary indicator bacteria (SIB) such as aerobic bacteria and coliform group as well as pathogenic indicator bacteria (PIB) such as Staphylococcus aureus, E.coli, Salmonella spp., Listeria monocytogenes, and Bacillus cereus. The results indicated that SIB in primary materials was detected as low as 3 log units and E.coil and Staphylococcus aureus of PIB were detected. After grinding process, aerobic bacteria, fungi, and coliform group increased 52% and 108%, respectively. In final products, PIB was not detected except for one found Staphylococcus aureus by which workers' hands were contaminated. Moreover, UV detectors in all the manufacturers were not able to reduce bacteria. Thus, this data suggest that a stringent safety management be needed to prevent cross contamination, and also reconsider effectiveness of facility.

Little evidence has been provided on the standardization of community dental hygiene as one of the subjects of dental hygiene course. The goals of this study were to: examine the satisfaction of a dental hygiene student's in the practice program according to public health centers and explore the satisfaction factors of a dental hygiene student's in the program of public health center. Data on 105 were obtained from the undergraduate students in the university in Gyeonggi-do. As a result of satisfaction of the practice at 11 public health centers, the overall mean score was 5.3 out of 7 score. The means of satisfaction score were different cross public health centers with the 3.7 lowest and 6.8 highest score. Among the factors affecting satisfaction of the practice at public health center, 'comfortability of practice' was identified by 55.2%, followed by 'accessibility (46.7%)' and 'academic achievement (31.4%)'. Different proportions of respondents were obtained between 3rd year and 4th year students. In conclusion, this study highlighted the importance of the program of public health center for quality improvement of community oral health practice. A survey of the satisfaction of a dental hygiene student of community oral health practice is to provide evidence data as a starting point for this purpose.

Since the discovery that Mycobacterium aviumsubsp. paratuberculosis (Map) is the causative agent of Johne's disease (JD) in cattle at the end of the nineteenth century, movement of livestock latently infected with Map has led to the spread of JD throughout the world. A new form of enteritis with clinical features of JD in cattle appeared in humans concurrent with the appearance of Map as a disease problem in livestock. The demonstration that Map is a zoonotic pathogen and the causative agent of the new form of enteritis in humans, however, wasn't recognized until late in the twentieth century when methods were developed to detect the presence Map in tissues from patients with the new form of clinical enteritis. The objective of this short review is to provide a brief history explaining how Map has become a major disease problem in livestock and humans and then provide a review of the progress that has been made in treating patients with an enteritis caused by Map and the strategies underway to develop a vaccine to control infection in livestock.

Several new ion exchange resins have been synthesized from chloromethyl styrene-1, 4-di-vinylbenzene with 1%, 2%, 5% and 10%-crosslinking and macrocyclic ligands of cryptand type by interpolymerization method. The adsorption characteristics and the pH, time, solvents and concentration dependence of the adsorption of metal ions by this resin were studied. The correlation between the separation characteristics of uranium and transition metal on the resins and the stability constants of complexes with macrocyclic ligands have been examined. The resins were very stable in both acidic and basic media and had good resistance to heat at $280^{\circ}C$. The $UO_2^{2+}$ aqueous solution was not adsorbed on the resins below pH 3.0, but the power of adsorption of $UO_2^{2+}$ increased rapidly above pH 4.0. The optimum equilibrium time for adsorption of metallic ions was twenty minutes and adsorptive power decreased in proportion to crosslinking size of the resins and order of dielectric constants of solvents used and the selective sequence for metal cations is in the order of $UO_2^{2+}$, $Cu^{2+}$ and $Ce^{3+}$ .
