2007 Korean National Growth Charts were published by The Korean Pediatric Society and Korea Centers for Disease Control and Prevention in October, 2007. These Growth Charts are composed of Growth Curves and Tables, which are based on the principles such as pooling data of the different generations and application of LMS method. In this review, several tips of application using these new charts are summarized with points of view both in clinical and research fields.

When curing the composite restorations with light curing units, the light guides are often in direct contact with oral tissues, therefore contamination of light guides is inevitable. Curing light guides fall into the "semicritical" instrument category according to the Centers for Disease Control and Prevention (CDC) and must be heat or vapor-sterilized or at a minimum, these semicritical instruments must be sterilized in a liquid chemical agent. Currently, most common methods of maintaining sterility of the light guides are wiping the guide with a disinfectant, such as glutaraldehyde, after each patient use; using autoclavable guides; using presterilized, single-use plastic guides; and using translucent disposable barriers to cover the guide.

objective: A suggestion of the projected workforce of Certified Infection Control Nurse in Korea Methods : I) Demand model was used for the projected workforce of Certified Infection Control Nurse . 2) Time series regression equation was used for the suggestion of the number of general hospitals and hospitals 3) Expert in infection control were contacted to get an opinion and information about the criteria of distribution and scope of Certified Infection Control Nurse. 4) National and international internet data were collected. 5) The demand of Certified Infection Control Nurse were analyzed by legislative criteria and recommended criteria of advanced nation (1) Maximal demand of Certified Infection Control Nurse: full responsibility and intra hospital concurrent responsibility (2) Minimal demand of Certified Infection Control Nurse: full responsibility and inter hospital concurrent responsibility (3) Demand of SENIC project of CDC in U.S.A: 1 Certified Infection Control Nurse every 250 beds. Results: In maximal demand. there will be 559 Certified Infection Control Nurse needed in 2002, and 746 in 2010. In minimal demand, there will be 272 Certified Infection Control Nurse needed in 2002, and 316 in 2010. On the basis of criteria of SENIC project. there will be 588-915 Certified Infection Control Nurse needed in 2002, 628-972 Certified Infection Control Nurse needed in 2010. Conclusion: In case of concurrent responsibility, intra hospital concurrent responsibility is more desirable than inter hospital concurrent responsibility, and infection control work must be major job in their work.

Healthcare-associated infections are a major concern in relation to patient safety. Of the numerous interventions for infection control, hand hygiene is the main factor that reduces the transmission of nosocomial pathogens. In this review, we cover the history of hand hygiene, evidence supporting its efficacy, and its importance. Then, we briefly introduce the 2017 hand hygiene guidelines of the Korea Centers for Disease Control and Prevention.

In China, the incidence rate of Hepatitis A has decreased from 56/100 000 in 1991 to 1.05/100 000 in 2020. The number of Hepatitis A outbreaks in China has decreased significantly, however, it has also happened in the last 5 years, and the risk still remains. In order to strengthen the technical guidance for the investigation and control of Hepatitis A outbreak, the Chinese Center for Disease Control and Prevention (China CDC) organized experts in related fields to compile this guideline. The main contents included outbreak definition, outbreak detecting and reporting, outbreak investigation and response, making conclusion and communication. This guideline is intended for use by staff at public health administrative departments, medical and health institutions, centers for disease control and prevention, health supervision agencies at different levels, and other relevant institutions, units and individuals. China CDC will update this guideline periodically based on the progress in this field and feedbacks during the implementation of this guideline.

BACKGROUND: The Korea Centers for Disease Control and Prevention (KCDC) has been providing a nationwide, one-day training program for workers of hospital blood centers once a year since 2013. We evaluated the achievement levels of the program through surveys. METHODS: The survey was conducted immediately after the program in 2015, 2016, and 2017. Respondents' occupations, institutions, program contents, and operational aspects were asked. RESULTS: The response rate was 56.2%∼73.2%. The occupations of respondents were medical technologists 66.9%∼75.7%, nurses 16.1%∼22.1%, and others (administrators, et al.) 1.5%∼11.3%. About 86.1%∼88.2% of respondents answered that the program as a whole was satisfactory or very satisfactory; 88.9%∼94.7% thought that it is necessary or very necessary; 77.9%∼84.1% answered that the appropriate length of the program was one day; 53.8%∼69.1% answered that the appropriate number of program is once per year; and 23.4%∼53.8% or 40.3%∼61.4% answered that the appropriate season for the program by the KCDC should be the first or the second quarter, respectively. CONCLUSION: This study suggests that the training program plays a useful role in meeting the needs of workers for hospital blood centers.

OBJECTIVES: This study was conducted to evaluate association between computerized neurobehavioral performance and blood lead concentration in Korean elementary school students. METHODS: The subjects were 1,077 elementary school students of Seoul, Busan, Daegu and Gwangju. Blood lead concentration was measured and computerized neurobehavioral performance tests were performed. RESULTS: Blood lead concentration of the subjects was in the range of 0.20 and 7.39 microg/dl. The geometric mean of the subjects' blood lead concentration was 1.41 microg/dl. As blood lead concentration increased, reaction time to the symbol digit tended to increase significantly and linearly. As a result of LOWESS(locally weighted scatterplot smoothing), increasing reaction time to the symbol digit was observed. CONCLUSIONS: As blood lead concentration under the CDC (center for disease control and prevention) reference value increased, reaction time to the symbol digit tended to increase. But, as the number of subjects over 3 microg/dl is small, it is difficult to make a definite conclusion. If confounding variables are controlled properly in a follow-up study, we can obtain a more definite conclusion.

Cytomegalovirus retinopathy(CMV)is a necrotizing retinitis which can occur as a late manifestation of the Acquired immunodeficiency syndromde(AIDS), which rapidly increases in number after original description of the disease in 1981 by Gottliebet al. We experienced a patient, who complained of decreased visual acuity of the left eye only we initially diagnosed the patient as CMV retinitis, and during the course of treatment, finally diagnosed the patient as CMV retinitis with AIDS, and the patient was subdivided into Group IV, Subgroup C by center for disease control classification system To our knowledge, for about 10% of the patient of the CMV retinopathy, AIDS was diagnosed like same manner as we did, but we couldn't find any report in korea, so we report this case with a review of literatures.

Allergy diagnosis and immunotherapy in Korea rely mostly on imported allergen extracts. However, some allergens that are not important in Western countries are not commercially available, and even the same species of allergen source often displays differences in allergenicity due to amino acid sequence polymorphisms. Therefore, it is essential to prepare allergen extracts that reflect regional characteristics. Allergen standardization has been performed since 2009 with the support of the Korea Center for Disease Control and Prevention. Here, we summarize the current status of allergen standardization, focusing on the house dust mite and cockroach. Pollen allergens that are under investigation are also briefly described.
