To study the microbiological contamination of kitchen dishcloths in Chinese housholds, 1010 'in-use' kitchen dishcloths were collected from residential premises in Beijing and Shanghai, and they were sent to the laboratory for microbiological quality analysis. The aerobic plate counts for dishcloths were 10-109 cfu/cm2 in the range of 150 cfu/cm2 to 1.776×109 cfu/cm2 (Beijing) and 62.5 cfu/cm2 to 8.75×108 cfu/cm2 (Shanghai). Nineteen species of bacteria were detected in the dishcloths, most of which were conditional pathogenic bacteria. This study found a significant difference in the aerobic plate counts of dishcloths with regard to type, number of the days used, activities used for, and some family factors. The findings of the study highlight the potential for contamination of kitchen dishcloths within homes.

The Korean Journal of Parasitology 2009;47(Suppl):S143-S153
Arthropods are important in human health, which can transmit pathogens to humans, parasitize, or produce important allergens. Allergy prevalence becomes higher in Korea recently as well as other developed countries in contrast to a decrease of infectious diseases. Allergic diseases caused by household arthropods have increased dramatically during the last few decades since human beings spend more their time for indoor activities in modernized life style. Household arthropods are one of the most common causes of allergic diseases. Biological characterization of household arthropods and researches on their allergens will provide better understanding of the pathogenesis of allergic diseases and suggest new therapeutic ways. Therefore, studies on arthropods of allergenic importance can be considered one of the major research areas in medical arthropodology and parasitology. Here, the biology of several household arthropods, including house dust mites and cockroaches, the 2 most well known arthropods living indoor together with humans worldwide, and characteristics of their allergens, especially the research activities on these allergens performed in Korea, are summarized.

BACKGROUND:
Among the environmental risk factors, household air pollution exposure from traditional cooking practices is one of the biggest killers globally, which mainly impacts developing countries where many families rely on traditional cooking practices. Although improved cookstove adoption is central to tackle this public health issue, the efforts to disseminate cookstove technologies have faced challenges, and the adoption rates are reported to be very low in many developing countries including Ethiopia. Therefore, this study aimed to determine the magnitude and identify potential factors that may act as facilitators or barriers to adoption from users' point of view.
METHODS:
As part of the wider stove trial project, a cross-sectional study was conducted among a total of 5830 households under randomly selected clusters. The required data were collected through face-to-face interviews, and a backward stepwise logistic regression analysis technique was applied to evaluate the effect of potential predictor variables on adoption using adjusted odds ratio (AOR) as measures of effect.
RESULTS:
The prevalence of adoption was found to be 12.3% (95% CI 11.5-13.2), and households headed by females (AOR 1.96; 95% CI 1.24-3.10), private house ownership (AOR 4.58; 95% CI 3.89-6.19), separate cooking location (AOR 1.84; 95% CI 1.49-2.78), fuel purchasing (AOR 2.13; 95% CI 1.64-2.76), health benefit (AOR 1.76; 95% CI 1.15-2.70), optimistic social interaction (AOR 1.81; 95% CI 1.46-2.26), traditional suitability (AOR 1.58; 95% CI 1.28-1.95), stove use demonstration experience (AOR 2.47; 95% CI 1.98-3.07), cheap price (AOR 2.48; 95% CI 1.91-3.21), availability (AOR 1.81; 95% CI 1.5-1, 2.17), fuel-saving benefit (AOR 1.63; 95% CI 1.18-2.24), and more durable stove (AOR 1.71; 95% CI 1.30-2.26) of cookstove played a significant role as facilitators to adoption. In addition, lower educational level of head (AOR 0.31; 95% CI 0.23-0.42) and fuel processing requirement (AOR 0.55; 95% CI 0.44-0.70) of cookstove were found to be barriers for adoption.
CONCLUSIONS
Extremely lower improved cookstove adoption was observed due to household- and setting-related, cookstove technology-related, user knowledge- and perception-related, and financial- and market development-related factors. Therefore, to gain successful adoption, implementers and policymakers should consider those important factors in the implementation of clean cooking solutions to the community.

The inactivation efficiencies of microorganisms were found to be enhanced by using silver solution together with ultraviolet light (UV-A, 395 nm) irradiation. The inactivation efficiencies were improved remarkably especially in eukaryotic microorganism. To make clear the inactivation mechanism of microorganisms by the combination effect of silver and ultraviolet light irradiation, the resultant solution was characterized by ESR (Electron spin resonance, ESR). Scanning electron microscopy (SEM) and the methnd for measuring enzyme activity of mitochondria for eukarvotic cells were used to conjecture the mechanism, by analysis of the morphological and physiologic changes in eukaryotic cells. It is proposed that silver oxide (Ag20) can be activated by ultraviolet light irradiation and react with water molecules to produce hydroxyl radical (.OH). Hydroxyl radical could damage cell wall of eukaryotic microorganisms, and inactivate the enzyme activity of mitochondria of eukaryotic microorganism cells. Accordingly, eukaryotic microorganism cells would die. In the experiment, Staphylococcus aureus was employed as the representative of prokaryotic microorganisms, and Candida albicans and Trichophyton mentagrophytes as the representative of eukaryotic microorganisms, respectively. Moreover, the results of the technology applied to washing machine were presented and discussed.

7.A Study on the Subjective Musculoskeletal Symptoms Associated with Tasks of Operating Room Nurses.
Journal of Korean Academy of Community Health Nursing 2005;16(3):351-359
PURPOSE: To find the factors of subjective musculoskeletal symptoms associated with the general characteristics and tasks of operating room nurses (OR nurses) and then to use the factors as basic information for preventing and managing musculoskeletal symptoms in OR nurses. METHOD: This study was an exploratory research. Data were collected using a self-report questionnaire from OR nurses working at 8 polyclinics in Korea during the period from July 26 2004 to August 19 2004. The questionnaire contains 7 questions on general characteristics and 18 questions on tasks in the operating room. RESULT: 187 (75.1%) nurses said they 'had' subjective musculoskeletal symptoms. Statistically significant differences were observed according to clinical career, career as an OR nurse, skillfulness, satisfaction with tasks in the operating room, perception on suitable treatment, care of symptoms by the hospital. weight of hospital linen and weight of a basic operation set (p<.05). CONCLUSION: Musculoskeletal symptoms complained of by OR nurses were significant. This may cause difficulties in nursing tasks in the operating room. Thus, various arrangements should be made for OR nurse with subjective musculoskeletal symptoms at the early stage.

8.Enhancement of Adenovirus Type 12 Transformation by N-Methyl-N-Nitro-N-Nitrosoguanidine.
Journal of the Korean Society of Virology 1997;27(2):257-260
Adenoviruses are icosahedral virions containing double-stranded linen DNA. They are 70 nm to 90 nm in diameter and capsid is composed of 252 capsomeres. Several members of this group, including types commonly associated with respiratory disease in man, are capable of producing malignant tumors in young hamsters and a few types have been shown to be oncogenic in young rat. Previous report involving effect of caffein on transformation induced by Adenovirus type 12 [9] has been carried out. The present report represents a continuation of previous study. To obtain evidence concerning the of(tract of MNNG (N-methyl-N'-nitro-N-nitroguanidine) on transformation, investigation of adenovirus type 12 of this group was undertaken. For practical consideration it was desirable to investigate the effect of MNNG on the adenovirus type 12-induced transformation in L cell. Results were as following 1. Adeno virus type 12 induced transformation was enhanced in the presence of MNNG. 2. Yields of adeno type 12 virus in L cell were slightly inhibited by treatment of MNNG.

This study was designed to investigate the effects on count, size, and morphology of human corneocytes when the skin is irritated with a rough towel. The desquamating portion of the stratum corneum was sampled with the detergent scrub technique every other day for 12 days. The following parameters were measured; numerical count, size (surface (mu)2), and shape (regular, irregular). Corneocytes from skin irritated with a rough towel differed from those of normal skin in that they were diminished by about 60% in count and were 14% smaller in size on the first experimental day. These parameters became normalized in count after 10 days and in size after 5 days respectively. On the morphological classification of the cell outlines, there were no significant differences from the control groupts except that there were slightly increased numbers of irregular cells in the experimental groups.

In mid-1987 a baseline microfilarial prevalence survey was conducted among five villages in the Mt Bosavi region of the Southern Highlands Province of Papua New Guinea. Through use of the Nucleopore filtration technique, it was determined that 48% of villagers had detectable microfilaraemia. The highest prevalence was documented in Fogomaiyu, where the microfilaraemia rate was 92%. On the basis of this initial survey and the expressed interest of the community, the Division of Health in the Southern Highlands Province undertook an integrated community-based pilot control program. The project used two principal control methods: (a) drug treatment with low-dose diethylcarbamazine citrate (DEC) distributed to the community weekly and (b) vector control with permethrin-impregnated bednets. Results six months after the intervention indicate that the program was successful in reducing microfilaraemia at Fogomaiyu village from 92% to 6%. The reduction is principally related to the effects of DEC, although the bednets, by limiting vector-person contact, are expected to reduce the incidence of both filariasis and malaria.
