PURPOSE: This study was conducted to describe mother's child-rearing attitudes and problem conduct of children as perceived by children and to examine correlation between maternal nurturing attitudes and child problem behavior. METHOD: The participants were 338 fifth and sixth graders who attended two randomly selected elementary schools in the city of G, Gangwon province. Child-rearing attitudes of the mother were rated on a 5-pointed scale that developed by Schaefer and added by Oh & Lee(1982). Problem conduct of children were rated on a 3-pointed scale of the K-YSR by Oh Kyung-Ja et al.(1997). The data were gathered from October 2 to October 28, 2004, and the collected data were analyzed with SPSS 10.0 program. RESULTS: For the children's perception of mother's child-rearing attitude, student had a relatively high mean scores of 3.70+/-0.44. Correlations between the mother's child-rearing attitude and general characteristics of the children showed statistically significantly different according to grade, father-mother relations, type of residence and extent to which father shared household chores. The mean score for problem conducts of children was 0.47+/-0.25.The average for their internal behavior problems was 0.52+/-0.33, and for external behavior problems was 0.44+/-0.24. There were statistically significantly differences in the behavior problem scores of the children according to the general characteristics of grade, education, occupation, mother-father relations, extent to which father shared in household chores and religion. As to correlation between mother's child-rearing attitude and their problem conduct, every type of attitude had a significantly moderate reverse correlation to every type of behavior problem of the children(r=-.431, p=.000). CONCLUSION: Mother's child-rearing attitudes might affect the problem conduct of children, and mother should try to treat their children with affection and respect, to maintain good relations with father, and to bring their children up coherently in an autonomous, permissive, positive and democratic manner.

BACKGROUND: Liver biopsy is the gold standard for assessing liver fibrosis; however, it has a relatively high risk of resulting in complications. Although a non-invasive method (i.e., transient elastography—fibroscan) was introduced, it is expensive and is dependent on the patient's status. Thus, the FIB-4 score, a non-invasive formula, has been used to predict the degree of liver fibrosis. The aim of this study was to evaluate the usefulness of the FIB-4 score in predicting stages of liver fibrosis. METHODS: We analysed the age, diagnosis, and liver stiffness of 282 patients by measuring the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) as well as their platelet count. Liver elasticity was evaluated by two classification criteria (Foucher et al. and Mueller et al.). The FIB-4 score was calculated using the formula: age×AST/(platelet count×ALT½). The cut-off value of the FIB-4 score was determined according to the area under the relative operating characteristic curve (AUC) based on liver elasticity. RESULTS: The FIB-4 cut-off values, as determined using two different criteria, have the highest AUC, thereby indicating a robust ability to distinguish between healthy liver tissue and the presence of any liver fibrosis. The FIB-4 score with a cut-off value of 2.07, as determined by Mueller et al., had the highest AUC (0.837) and odds ratio (2.741) with a sensitivity of 78.3% and a specificity of 76.5%. CONCLUSIONS: An FIB-4 score of 2.07 is a cut-off value that is useful in detecting fibrotic progression in chronic liver disease in our laboratory. Each laboratory should determine an appropriate FIB-4 cut-off value that is relative to the particular characteristics of their patient population.

BACKGROUND: Rapid and sensitive detection of transfusion adverse reaction is fundamental to reducing transfusion-related morbidity and mortality. The aim of this study was to develop an effective system for reporting of transfusion adverse reaction. METHODS: Inpatient lists with transfusion adverse reaction on a nurse electronic medical records (EMR) from December 4th, 2014 to May 21st, 2015 were automatically selected and displayed to the computer screen of the blood bank data management system. After review of clinical and laboratory data of suspected patients with transfusion reaction, frequency of transfusion adverse reaction according to blood components was calculated. RESULTS: The frequency of transfusion adverse reactions according to blood components was, in decreasing order, red blood cells (RBC) 0.91% (58/6,404), frozen fresh plasma (FFP) 0.20% (5/2,549), and platelets 0.10% (6/5,728). Of 47 allergic reactions, the relative ratio by blood components was RBC 76.6%, platelets 12.8%, and FFP 10.6%. All of 22 febrile nonhemolytic transfusion reactions were RBC related reactions. CONCLUSION: The online transfusion adverse reaction reporting system based on a nurse EMR is helpful in easy and accurate estimation of transfusion adverse reaction incidence.

BACKGROUND: Underweight is associated with increased mortality, relative to the normal weight category. The importance of managing underweight patients has not yet been recognized seriously in South Korea, and little information is available on the prevalence of underweight and its associated risk factors. This study aims to investigate changes in the prevalence of underweight by gender and age and analyze its trend.METHODS: Data were obtained from individuals aged >20 years, from the Korean National Health and Nutrition Examination Survey between 1995 and 2015. The subjects of this study included 134,613 adults (male, 61,152; female, 73,461). The prevalence of underweight was determined as defined by the Asia-Pacific Perspective, and socioeconomic factors associated with a predisposition to underweight were analyzed using the chi-squared test and multiple logistic regression analysis.RESULTS: Among Korean adults, the age-adjusted prevalence of underweight (body mass index < 18.5 kg/m²) was 3.1% in men and 6.3% in women. Overall, a U-shaped relationship was established between the prevalence of underweight by gender and age. There was no significant difference in socioeconomic factors related to the prevalence of underweight in men and women in their twenties. The prevalence of underweight in women aged 20–59 years showed an increasing trend (P for trends < 0.05).CONCLUSION: In individuals aged 20–29 years, the prevalence of being underweight was higher in women than in men. Recently, there has been an increasing trend in the prevalence of underweight young women of reproductive age. This requires national public health attention.

BACKGROUND: Equol, a metabolite of diadzein, is produced by some intestinal bacteria. Equol acts as an estrogen receptor agonist and has been reported to have several beneficial health effects. Leukocytes play an important role in the pathogenesis of autoimmune, metabolic, and cardiovascular diseases. Decreased leukocyte mitochondrial DNA (mtDNA) content, as an index of mitochondrial function, is associated with metabolic syndrome, bone mineral density, and aging. The possible association between equol production and leukocyte mitochondrial function has not been studied to date. Therefore, we investigated whether equol production is associated with leukocyte mtDNA copy number in postmenopausal women. METHODS: This observational cross-sectional study included 71 postmenopausal women. They completed a lifestyle questionnaire and medical history. In addition, a dietary assessment using a 24-hour recall method and food frequency questionnaire, anthropometric evaluation, and blood sampling were conducted. Serum equol concentration was measured in the fasting state. Leukocyte mtDNA copy number was measured by real-time polymerase chain reaction. RESULTS: Among older females, 33.8% were equol producers. The leukocyte mtDNA copy number was lower in non-equol producers versus equol producers. Furthermore, the leukocyte mtDNA copy number was positively associated with the serum equol concentration (r=0.42, P<0.01). Stepwise multiple regression analysis showed that equol production (beta=47.864, P<0.01) was an independent factor associated with mtDNA copy number. CONCLUSIONS: Equol production was associated with elevated mtDNA content in the peripheral blood of postmenopausal women. This finding suggests that the beneficial health effects of equol in postmenopausal women may be related to increased mitochondrial function.

This study was conducted to determine whether the size of an enterprise can make a difference to workers' health and to examine those factors, which influence workers' health. The subjects of this study included 26,324 workers employed in manufacturing industry who received medical examinations at the Industrial Health Center at Yonsei University in 1995, 1996 and 1997. Medical examination data were used as a measure of health. Each enterprise was classified by size into three categories: Small scale enterprises (SSE) that employ no more than 50 regular employees; middle scale enterprise (MSE) that employ from 50 to 300 regular employees; and large scale enterprise (LSE) that employ more than 300 regular employees. Health conditions, according to the size of the enterprise, were determined by comparing prevalence rates, and direct standardization methods were used based upon the Korean population, as a standard population, in order to adjust for differences in population structure. 1. The findings of the medical examinations showed that, the prevalence rate in SSEs was higher than in MSEs or LSEs, but that this relationship was reversed after standardizing for sex and age. 2. Logistic regression analysis showed that, although subjects of advanced age, prolonged work history, and male gender had higher risks of disease, the size of the enterprise had no significant effect upon these risks.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious zoonosis caused by the SFTS virus. Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome associated with excessive immune activation. Cytokine storms are often seen in both SFTS and HLH, resulting in rapid disease progression and poor prognosis. The aim of this study was to identify whether SFTS cases complicated by HLH are related to higher rates of mortality. Descriptive analysis of the frequency of clinical and laboratory data, complications, treatment outcomes, and HLH-2004 criteria was performed. Cases presenting with five or more clinical or laboratory findings corresponding to the HLH-2004 diagnostic criteria were defined as SFTS cases complicated by HLH. Eighteen cases of SFTS were identified during a 2-year study period, with a case-fatality proportion of 22.2% (4 among 18 cases, 95% confidence interval 9%–45.2%). SFTS cases complicated by HLH were identified in 33.3% (6 among 18 cases). A mortality rate of 75% (3 among 4 cases) was recorded among SFTS cases complicated by HLH. Although there were no statistically significant differences in outcomes, fatal cases exhibited more frequent correlation with HLH-2004 criteria than non-fatal cases [3/14 (21.4%) vs. 3/4 (75%), p=0.083]. In conclusion, the present study suggests the possibility that SFTS cases complicated by HLH are at higher risk of poor prognosis.

BACKGROUND AND OBJECTIVES: We evaluated the effectiveness of genotype- and phenotype-directed individualization of P2Y12 inhibitors to decrease high on-treatment platelet reactivity (HOPR). SUBJECTS AND METHODS: Sixty-five patients undergoing percutaneous coronary intervention for non-ST elevation acute coronary syndromes were randomly assigned to genotype- or phenotype-directed treatment. All patients were screened for CYP2C19*2, *3, or *17 alleles by using the Verigene CLO assay (Nanosphere, Northbrook, IL, USA). The P2Y12 reaction unit (PRU) was measured using the VerifyNow P2Y12 assay (Accumetrics, San Diego, CA, USA). 21 CYP2C19 *2 or *3 carriers (65.6%) and 11 patients with HOPR (33.3%), defined as a PRU value > or =230, were given 90 mg ticagrelor twice daily; non-carriers and patients without HOPR were given 75 mg clopidogrel daily. The primary endpoint was the percentage of patients with HOPR after 30 days of treatment. RESULTS: PRU decreased following both genotype- and phenotype-directed therapies (242+/-83 vs. 109+/-90, p<0.001 in the genotype-directed group; 216+/-74 vs. 109+/-90, p=0.001 in the phenotype-directed group). Five subjects (16.2%) in the genotype-directed group and one (3.3%) in the phenotype-directed group had HOPR at day 30 (p=0.086). All patients with HOPR at the baseline who received ticagrelor had a PRU value of <230 after 30 days of treatment. Conversely, clopidogrel did not lower the number of patients with HOPR at the baseline. CONCLUSION: Tailored antiplatelet therapy according to point-of-care genetic and phenotypic testing may be effective in decreasing HOPR after 30 days.

BACKGROUND: Curcumin is a naturally occurring biologically active compound, and it has been shown to possess potent anti-inflammatory, anti-tumor and anti-oxidative properties. It is known for its anti-proliferative and proapoptotic effects in several cancer cells. Curcumin's effects on the mechanisms of cell survival and the expression of various cytokines were investigated in U266 cells and the in vivo effects of curcumin were examined using an animal model. METHODS: Cell proliferation assay and flow cytometry were used to examine cell proliferation, along with cell cycle analysis. The protein expressions were analyzed by Western blotting and the expressed levels of cytokines were analyzed by the ELISA method. RESULTS: Curcumin inhibited U266 cell growth in a dose-dependent and time-dependent manner. Cell cycle analysis showed an increased sub-G1 phase, a down regulated cyclinD1 expression and an induced p21 expression. Apoptosis induced a down regulated procaspase 3 expression and it induced cleaved PARP. Curcumin inhibited the IL (interleukin)-6 induced cell signal pathway via decreasing the STAT1 an 3, Erk cyclinD1 and c-myc expressions. Also, administration of 25mg/kg curcumin to a U266 animal model inhibited cancer cell engraftment in the bone marrow and it decreased the IL-6, sIL-6R and IL-8 expression levels. CONCLUSION: Curcumin induced cell cycle arrest and apoptosis and it inhibited the IL-6 mediated signal transduction pathways in U266 cells. Similar to the in vitro results, curcumin inhibited cancer cell proliferation and the expression of cytokine in vivo.

This paper describes a community effort to improve earlier versions of the full-text corpus of Genomics & Informatics by semi-automatically detecting and correcting PDF-to-text conversion errors and optical character recognition errors during the first hackathon of Genomics & Informatics Annotation Hackathon (GIAH) event. Extracting text from multi-column biomedical documents such as Genomics & Informatics is known to be notoriously difficult. The hackathon was piloted as part of a coding competition of the ELTEC College of Engineering at Ewha Womans University in order to enable researchers and students to create or annotate their own versions of the Genomics & Informatics corpus, to gain and create knowledge about corpus linguistics, and simultaneously to acquire tangible and transferable skills. The proposed projects during the hackathon harness an internal database containing different versions of the corpus and annotations.
