PURPOSE: This study was performed to identify factors associated with human papillomavirus vaccination intention among unvaccinated nursing students. METHODS: Two hundred-and-five female nursing students from three universities completed self-administered questionnaires including participants' characteristics, human papillomavirus-related knowledge, attitude toward human papillomavirus vaccination, and human papillomavirus-related health beliefs. Multivariate logistic regression analysis was used to determine significant independent predictors of human papillomavirus vaccination intention. RESULTS: Of 205 participants, 134 (65.4%) reported an intention to obtain a vaccination against human papillomavirus. As a result of the analysis of the bivariate relationships, family history of cervix cancer, perceived needs, importance of prevention, perceived susceptibility, perceived benefit, and perceived barrier were significantly related to vaccination intention. A multivariate logistic regression model identified factors of human papillomavirus vaccination intention: higher importance of prevention (Adjusted Odds Ratio [AOR]: 4.20, 95% Confidence Interval [CI]: 1.73~10.19), higher perceived benefit (AOR: 6.94, 95% CI: 2.01~23.98), lower perceived barrier (AOR: 0.39, 95% CI: 0.20~0.73). CONCLUSION: The results of this study indicated significant factors influencing the intention to obtain human papillomavirus vaccination in unvaccinated nursing students. Also, the importance of prevention, perceived susceptibility, perceived benefit, and perceived barrier in obtaining human papillomavirus vaccination should be taken into account when developing educational programs.

PURPOSE: The purpose of this study was to examine the relationship between perceived work environment and workplace bullying among Korean intensive care units (ICU) nurses. METHODS: This is a descriptive survey research, with 134 ICU nurses from five hospitals in Korea. The work environment was measured by the Korean Nursing Work Environment Scale. Workplace bullying was measured with the Korean version of the Negative Acts Questionnaire-Revised. RESULTS: ICU nurses reported moderate satisfaction with their work environment, with perception of the basic work system receiving the highest scores. A total of 94.0% of ICU nurses have experienced at least one negative act within the past 6 months, and the prevalence of bullying was 17.2% according to operational bullying criteria. The ICU nurses reported that they experienced more work-related bullying than other types of bullying. Significant negative correlations between the nursing work environment and workplace bullying were found. CONCLUSION: These findings indicate that the better the nursing work environment, the less workplace bullying nurses will experience. Further research needs to be done to identify factors that influence bullying in the nurses and to develop an intervention that prevents workplace bullying.

BACKGROUND: The stem bark of Kalopanax pictus (KP) has been used in traditional medicine to treat rheumatoidal arthritis, neurotic pain and diabetes mellitus in China and Korea. In this study, the mechanism responsible for anti-inflammatory effects of KP was investigated. METHODS: We examined the effects of KP on NO production, nitric oxide synthase (iNOS) and HO-1 expression, NF-kappaB, Nrf2 and MAPK activation in mouse peritoneal macrophages. RESULTS: The aqueous extract of KP inhibited LPS-induced NO secretion as well as inducible iNOS expression, without affecting cell viability. KP suppressed LPS-induced NF-kappaB activation, phosphorylation and degradation of IkappaB-alpha, phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) and c-Jun N-terminal kinase (JNK). Furthermore, KP induced HO-1 expression and Nrf2 nuclear translocation. CONCLUSION: These results suggest that KP has the inhibitory effects on LPS-induced NO production in macrophages through NF-kappaB suppression and HO-1 induction.

OBJECTIVES: Heavy metals ingested through the consumption of aquatic products can accumulate in the human body over the long-term and cause various health problems. This study aims to present comprehensive data on the amount of heavy metals found in fish and shellfish in Korea using a systematic review of studies that report on that issue. METHODS: The study used the following databases: PubMed, Korean Studies Information Service System, and Research Information Sharing Service. The search terms for PubMed included fish OR shellfish OR seafood AND mercury OR cadmium OR lead OR heavy metal AND Korea. The search terms for Korean Studies Information Service System and Research Information Sharing Service included eoryu sueun, eoryu kadeumyum, eoryu nab, eoryu jung-geumsog, paeryu sueun, paeryu kadeumyum, paeryu nab, paeryu jung-geumsog, eopaeryu sueun, eopaeryu kadeumyum, eopaeryu nab, and eopaeryu jung-geumsog. RESULTS: A total of 32 articles were selected for review. The total mercury, lead, and cadmium concentrations in fish and shellfish reported in each of the articles are summarized, as are the species of fish and shellfish with relatively high concentrations of heavy metals. Total mercury concentrations tended to be higher in predatory fish species, such as sharks, billfishes, and tuna, while lead and cadmium concentrations tended to be higher in shellfish. CONCLUSION: This paper is the first to report a comprehensive summary of the concentrations of heavy metals in fish and shellfish. This data could be used as evidence to protect Koreans from exposure to heavy metals due to the consumption of highly polluted aquatic products.

Background: The Continuous Quality Improvement program for cytopathology in 2020 was completed during the coronavirus pandemic. In this study, we report the result of the quality improvement program. Methods: Data related to cytopathology practice from each institute were collected and processed at the web-based portal. The proficiency test was conducted using glass slides and whole-slide images (WSIs). Evaluation of the adequacy of gynecology (GYN) slides from each institution and submission of case glass slides and WSIs for the next quality improvement program were performed. Results: A total of 214 institutions participated in the annual cytopathology survey in 2020. The number of entire cytopathology specimens was 8,220,650, a reduction of 19.0% from the 10,111,755 specimens evaluated in 2019. Notably, the number of respiratory cytopathology specimens, including sputum and bronchial washing/ brushing significantly decreased by 86.9% from 2019, which could be attributed to the global pandemic of coronavirus disease. The ratio of cases with atypical squamous cells to squamous intraepithelial lesions was 4.10. All participating institutions passed the proficiency test and the evaluation of adequacy of GYN slides. Conclusions Through the Continuous Quality Improvement program, the effect of coronavirus disease 2019 pandemic, manifesting with a reduction in the number of cytologic examinations, especially in respiratory-related specimen has been identified. The Continuous Quality Improvement Program of the Korean Society for Cytopathology can serve as the gold standard to evaluate the current status of cytopathology practice in Korea.

Since 1995, the Korean Society for Cytopathology has overseen the Continuous Quality Improvement program for cytopathology laboratories. The Committee of Quality Improvement has carried out an annual survey of cytology data for each laboratory and set standards for proficiency tests. Methods: Evaluations were conducted four times per year from 2008 to 2018 and comprised statistics regarding cytology diagnoses of previous years, proficiency tests using cytology slides provided by the committee, assessment of adequacy of gynecology (GYN) cytology slides, and submission of cytology slides for proficiency tests. Results: A total of 206 institutes participated in 2017, and the results were as follows. The number of cytology tests increased from year to year. The ratio of liquid-based cytology in GYN gradually decreased, as most of the GYN cytology had been performed at commercial laboratories. The distribution of GYN diagnoses demonstrated nearly 3.0% as atypical squamous cells. The rate for squamous cell carcinoma was less than 0.02%. The atypical squamous cell/squamous intraepithelial lesion ratio was about 3:1 and showed an upward trend. The major discordant rate of cytology-histology in GYN cytology was less than 1%. The proficiency test maintained a major discordant rate less than 2%. The rate of inappropriate specimens for GYN cytology slides gradually decreased. Conclusions: The Continuous Quality Improvement program should be included in quality assurance programs. Moreover, these data can contribute to development of national cancer examination guidelines and facilitate cancer prevention and treatment.

OBJECTIVE: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases METHODS: 11 hospitals participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. RESULTS: Between Apri1 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. Most of the HAVS cases came from shipbuilding, and 172 of them (92.7 %) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9 %). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6 %) and 4 (12.1 %) cases of occupational asthma, the agents included isocyanate and welding fume, respectively. 64.7 % of the cases of occupational skin diseases were contact dermatitis, and organic solvents and welding fume were the main agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10 (58.8 %) of the cases were diagnosed as squamous cell carcinoma and 5 (29.4 %) as adenoma. CONCLUSION: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.
