BACKGROUND: The Automated Fluorescent Immunoassay System (AFIAS) rotavirus assay (Boditech Med Inc., Chuncheon, Korea) is a new rapid antigen test for rotavirus detection. We evaluated the performance of this assay for detecting rotaviruses and their specific genotypes in clinical stool samples. METHODS: AFIAS rotavirus assay was performed in 103 rotavirus-positive and 103 rotavirus-negative stool samples (confirmed by both PCR and ELISA), and its results were compared with those of PCR, ELISA, and immunochromatographic assay (ICA). We evaluated diagnostic sensitivity/specificity, the detectability of rotavirus subtypes, lower limit of detection (LLOD), reproducibility, cross-reactivity, and interference of AFIAS rotavirus assay. RESULTS: Based on PCR and ELISA results, diagnostic sensitivity and specificity of the AFIAS rotavirus assay were both 99.0%. LLOD results showed that the AFIAS assay had sensitivity similar to or greater than ICA and ELISA. High reproducibility was confirmed, and no cross-reactivity or interference was detected. This assay could detect genotypes G1P[8], G2P[4], G3P[8], G4P[6], G4P[8], G8P[4], G8P[8], G9P[4], and G9P[8]. CONCLUSIONS: The AFIAS rotavirus assay showed high reproducibility, sensitivity, and specificity as well as excellent agreement with ELISA, PCR, and ICA. It detected the most common as well as unusual genotypes of rotavirus prevalent in Korea. It could be a useful on-site assay for rapid, convenient, and cost-effective detection of rotavirus infection.

The infection status of digenetic trematode metacercariae (DTM) was investigated in fishes from coastal lakes in Gangwon-do, the Republic of Korea (Korea). All fishes collected in 5 lakes were examined with the artificial digestion method. More than 10 species, i.e., Metagonimus spp., Pygidiopsis summa, Centrocestus armatus, Metorchis orientalis, M. taiwanensis, Clinostomum complanatum, Echinostoma spp., Stictodora spp., Diplostomum sp. and Diplostomid No. 1. by Morita (1960), of DTM were detected in fishes from 5 coastal lakes in Gangwon-do. Metagonimus spp. metacercariae were found in 52 (41.3%) out of 126 sea rundace, Tribolodon hakonensis, from 5 lakes, and their density was 14.6 per fish infected. P. summa metacercariae were detected in 48 (84.2%) out of 57 mullets from 5 lakes, and their density was 316 per fish infected. C. armatus metacercariae were detected in 7 (14.6%) T. hakonensis and 3 (15.0%) Tridentiger brevispinis from Hyang-ho, and 5 (19.2%) Acanthogobius flavimanus from Gyeongpo-ho. Stictodora spp. metacercariae were found in 4 fish species, i.e., Tridentiger obscurus, Tridentiger trigonocephalus, Chelon haematocheilus, and Acanthogobius lactipes, from Gyeongpo-ho. Total 15 C. complanatum metacercariae were detected in 2 (9.1%) crucian carp, Carassius auratus, from Songji-ho. M. taiwanensis metacercariae were found in T. hakonensis from Hyang-ho and Gyeongpo-ho and in Pseudorasbora parva from Gyeongpo-ho. Total 11 M. orientalis metacercariae were detected in 3 (6.3%) T. hakonensis from Hyang-ho. From the above results, it was confirmed that various species of DTM are infected in fishes from coastal lakes in Gangwon-do, Korea.

BACKGROUND: Exposure to mercury is known to affect the nervous system and cardiovascular system, but effects of chronic exposure to mercury remain unclear. This study aimed to investigate the effects of high blood mercury concentrations on the health of patients living in the Yeong-dong region.METHODS: We analyzed the relationship between blood mercury concentration and cardiovascular risk and neuropathic symptoms for 555 patients whose blood mercury concentration was tested from 1999 to 2017. We analyzed the association of each lipid component and blood mercury concentration through a partial correlation method. We performed an analysis to determine the odds ratios (ORs) of hypertension, diabetes mellitus, and obesity to high blood mercury levels through a logistic regression model. We analyzed the association between mercury levels and neuropathic symptoms using a χ² test and calculated the OR.RESULTS: The average blood mercury concentration was 8.1±7.5 µg/L and 5.5±5.2 µg/L for males and females, respectively. There was a positive correlation of mercury concentration with high density lipoprotein cholesterol (r, 0.268, 0.219; P-value, <0.001). Among other cardiovascular disease risk factors, no significant correlation was found with high blood mercury level. A tingling sensation in females was related to a high blood mercury level (OR, 2.080; 95% confidence interval, 1.119–3.866).CONCLUSION: It was found that higher mercury concentrations could affect high-density lipoprotein cholesterol regardless of sex and can cause a tingling sensation in women.

In 2017, small, elliptical, brownish purple spots on spears and ferns of asparagus were found in fields of Gangwon-do. The isolated fungal species was identified as an ascomycete Stemphylium vesicarium based on morphological characteristics and molecular phylogenic analyses including nucleotide sequences of the internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and cytochrome b (cytb). A pathogenicity test revealed that S. vesicarium was the causal agent of purple spot disease on asparagus. The occurrence of purple spots caused by S. vesicarium on asparagus is the first report in Korea.

Since 2000, large amounts of rabies bait vaccine have been distributed in two provinces where raccoon dog-mediated rabies has occurred. A total of 146 raccoon dogs were caught in Gangwon and Gyeonggi Provinces from January 2017 to June 2018, and raccoon dog blood samples were collected. Of the 146 raccoon dogs, 13.7% (20/146) had rabies antibodies. In Gyeonggi and Gangwon provinces, the rate of rabies antibody was 8.5% (5/59) and 17.2% (15/87), respectively. Considering these results, it would be desirable to improve the distribution method or use a new bait vaccine to prevent animal rabies in South Korea.

6.A Study on the Relationship between the Spatial Cluster Patterns of Male Suicide Rate and the Regional Characteristics in South Korea
Health Policy and Management 2019;29(3):312-322
BACKGROUND: Since 2003, Korea has consistently shown the highest suicide rate among the Organization for Economic Cooperation and Development countries, and suicide remains the major cause of death. In particular, men are 2–3 times more likely to commit suicide than women, which called the ‘gender paradox of suicide.’ The areas with frequent suicide have spatially clustered patterns because suicide with a social contagion spreads around the neighborhood. The purpose of this study was twofold. The first was to estimate the hotspot areas of age-standardized male suicide mortality from 2008 to 2015. The second was to analyze the relationship between the hotspot areas and the regional characteristics for study years. METHODS: The data was collected through the Korean Statistical Information Service. The study areas were 227 si · gun · gu administrative districts in Korea. The hotspot area was used as a dependent variable. Socio-demographic variables (number of marriages per 1,000 population, number of divorces per 1,000 population, and urbanization rate), financial variables (financial independence and social security budget), and health behaviors (EuroQol-5 dimension [EQ-5D], and depression experience rate) were used as independents variables. RESULTS: The hotspot areas were commonly located in Gangwon-do, Chungcheongnam-do, Gyeongsangbuk-do, and Chungceongbuk-do. According to the results of panel logit regression, the number of divorces per 1,000 population, social security budget, and EQ-5D were statistically significant variables. CONCLUSION: The results of hotspot analysis showed the need for establishing a prevention zone of suicide using hotspot areas. Also, medical resources could be considered to be preferentially placed in the prevention zone of suicide. This study could be used as basic data for health policymakers to establish a suicide-related policy.

7.A Structural Equation Model for Happiness in Mothers with Young Children
Journal of Korean Academy of Nursing 2019;49(3):241-253
PURPOSE: This study aimed to develop and test a model of the happiness of mothers with young children based on the stress-coping-adaptation model of Lazarus and Folkman. METHODS: The data collection period was from May to July 2016. A self-report questionnaire was used to collect data from 210 mothers with children under 5 years of age living in Seoul, Gyeonggi, and Gangwon provinces. The exogenous variable was parenting stress, and the endogenous variables were parenting alliance, depression, optimism, ways of coping, and happiness. Data from 201 questionnaires were analyzed using the SPSS 22.0 and AMOS 20.0 programs. Data analyses included descriptive statistics, factor analysis, and structural equation modeling. RESULTS: The final modified model showed a reasonable fit to the data, and out of 25 paths, 13 were statistically significant. This model explained 78.4% of the variance in the happiness of mothers with young children and confirmed that depression, optimism, parenting alliance, and social support-focused coping have a direct effect on the subject's happiness. Parenting stress also influenced happiness through parenting alliance, depression, and optimism. CONCLUSION: In order to bolster the happiness of mothers with young children, positive psychological interventions that can minimize psychological vulnerabilities, such as depression, and that can enhance their strengths, such as optimism, may serve as effective ways of coping with and adapting to stress.

Journal of Korean Clinical Nursing Research 2019;25(2):198-207
PURPOSE: The purpose of this study was to provide data to establish an efficient manpower management plan so that the organization can identify the influence of organizational silence and professionalism on job embeddedness among nurses in hospital management. METHODS: Self-report questionnaires were distributed to 150 nurses in hospital management who were working in general hospitals with less than 900 beds but more than 300 beds in the districts of Seoul and Gyunggi, Gangwon province. Of the questionnaires, 127 out of 150 copies were collected and 120 copies were used for final analysis. Seven were not considered sincere in the responses. Data were analyzed using SPSS ver. 22.0 statistic program, t-test, ANOVA, Scheffé test, Pearson correlation coefficients and multiple regression. RESULTS: Organizational silence and professionalism had significant influence on job embeddedness, which explained 43.4% of job embeddedness. CONCLUSION: The results indicate that in order to raise job embeddedness, it is necessary to provide various programs to change communication patterns in the nurses in hospital management, and to create environments in which nurses in hospital management can present various opinions.

BACKGROUND: Local symptoms and signs of snake envenomation mimic the clinical features of compartment syndrome. It is important to measure the intracompartmental pressure to diagnose compartment syndrome. In this study, we present our experiences of confirming compartment syndrome and performing fasciotomy in snakebite patients based on high intracompartmental pressure findings. METHODS: The medical records of patients who visited the trauma center of Wonju Severance Christian Hospital from January 2010 to December 2015 for the management of venomous snakebite were retrospectively reviewed. Starting in 2014, fasciotomy was performed in patients with an intracompartmental pressure of more than 40 mmHg in addition to the clinical symptoms of compartment syndrome. RESULTS: A total of 158 patients with snakebite came to the hospital within 48 hours for treatment. Most patients (110 patients) were bitten at the upper extremities (69.6%). Since 2014, 33 out of 59 patients were suspected to have compartment syndrome, and their intracompartmental pressures were measured. Seventeen of those patients had a high intracompartmental pressure (average, 49.6 mmHg; range, 37–88 mmHg), and fasciotomy was performed. CONCLUSIONS: In this study, as many as 10.8% of all cases were in need of fasciotomy when compartment syndrome was diagnosed by measuring the intracompartmental pressure. Previously, it was reported that fasciotomy was not required in many cases of compartment syndrome originating from snakebite. However, some patients may develop very severe compartment syndrome, requiring fasciotomy.

After gastrojejunostomy, a small space can occur between the jejunum at the anastomosis site, the transverse mesocolon, and retroperitoneum, which may cause an intestinal hernia. This report presents a rare case of intestinal ischemic necrosis caused by retroanastomotic hernia after subtotal gastrectomy. A 56-year-old male was admitted to Kangwon National University Hospital with melena, abdominal pain, and nausea. His only relevant medical history was gastrectomy due to stomach cancer. Endoscopic findings revealed subtotal gastrectomy with Billroth-II reconstruction and a bluish edematous mucosal change with necrotic tissue in afferent and efferent loops including the anastomosis site. Abdominopelvic CT showed strangulation of proximal small bowel loops due to mesenteric torsion and thickening of the wall of the gastric remnant. Emergency laparotomy was performed. Surgical findings revealed the internal hernia through the defect behind the anastomosis site with strangulation of the jejunum between 20 cm below the Treitz ligament and the proximal ileum. Roux-en-Y anastomosis was performed, and he was discharged without complication. Retroanastomotic hernia, also called Petersen's space hernia, is a rare complication after gastric surgery, cannot be easily recognized, and leads to strangulation.
