Objective : Korean Version of Beck-II Depression Inventory to verify the reliability and validity of the proposed standards are practical and standardized, cut-off score by establishing a baseline indicating the presence of depression and depression On in the evaluation was to evaluate the clinical usefulness. Methods : 739 patients with major depression using the SCID and normal controls were 302 study subjects. Of patients with clinically significant medical condition, or psychotic disorders, organic mental disorder, epilepsy or seizure disorder, eating disorders are associated with patients taking anti-convulsants experienced in the past, patients were excluded from the study. Results : The main findings of this study were as follows. First, with respect to the KBDI-II items, the correlation between them ranged from 0.51 to 0.74, and was 0.60 over all questions. Further, the overall correlation of the KBDI-II plates showing confidence 'normal' than it was verified that. Second, the BDIII was used in each group to examine internal consistency and thus, whether Cronbach's alpha values were greater than 0.94. Third, the principal component analysis sought to extract factors in a way consistent with the results inspected last 3 factors were extracted and the total variance explained was 47.3%. Fourth, the Cutting calculated the score on the KBDI-II for ROC (Receiver operator characteristic) analysis yielding 18 dot, with the highest sensitivity and specificity was seen. Conclusion : Based on the results of this Study, the KBDI-II cut-off point should be valid as prescribed in 18 is considered.

Purpose : Indomethacin treatment is successful in about 90% of patent ductus arteriosus (PDA) in premature infants, but in some, repeated administration or surgical closure is required. The object of the present study is to determine the factors affecting the efficacy of indomethacin treatment and to predict the treatment result. Method : The 29 preterm neonates, admitted to neonatal intensive care unit of Kyunghee university medical center and Eulji university hospital between September 2002 and April 2006 were diagnosed of PDA and treated with indomethacin. The risk factors that might affect the efficacy of treatment were studied retrospectively. Results : The single-administered group was 19 patients out of 29 (65.5%) and among the repeated-administered group, 5 patients (17.2%) had repeated indomethacin administration and the other 5 patients (17.2%) underwent surgery due to reopening of the duct after repeated medical treatment. In repeated-administered group, the diameter of PDA was significantly larger ($3.66{\pm}0.8mm$ vs $2.55{\pm}0.8mm$, P<0.01), especially when larger than 3.5 mm (sensitivity: 70%, specificity: 89%). Also, the mean postnatal age of the first indomethacin administration was significantly delayed in repeated-administered group (19.7 days vs 12.5 days, P<0.05). There were no significant differences in gestational age (32 wk 5 days vs 30 wk 8 days) and in birth weight (1598.9 g vs 1750.5 g). There were no significant differences in associated morbidities. Conclusion : In patients with larger diameter of PDA (>3.5 mm) and older postnatal age (>7 days), the effect of indomethacin was decreased. Therefore in such cases, repeated dose of indomethacin or surgical ligation should be considered earlier.

This study was designed to examine the validity of HPR subscale in Korean Personality Inventory for Children(KPI-C) and Attention Problems subscale in Korean Child Behavior Checklist(K-CBCL) as diagnostic tool for Attention-Deficit/Hyperactivity Disorder(ADHD). Nineteen ADHD-1 type, twenty-three ADHD-H type, sixteen Neurosis, and fifteen normal children with the age from 6 to12 were selected based on DSM-IV, and their responses of the KPI-C and CBCL were analyzed. Omnibus F-test results showed that there were significant differences in the F scores of HPR and Attention Problems T scores(p<.05). But in Posthoc analysis, the HPR and AP scores in three clinical groups were significantly higher than in normal group, but there was no group difference among three clinical groups(p<.05). These results shows that HPR subscale and Attention Problems subscale may be useful tools for screening clinical groups(vs normal group) but there was a limit to the clinical validity of two subscales as diagnostic tools for the subtypes of ADHD.
Bovine blood, cell, tissue, and organ are used as raw materials for manufacturing biopharmaceuticals, tissue engineered products, and cell therapy. Manufacturing processes for the biologicals using bovine materials have the risk of viral contamination. Therefore viral validation is, essential in ensuring the safety of the products. Bovine herpesvirus type 1 (BHV-1) is the most common bovine pathogen found in bovine blood, cell, tissue, and organ. In order to establish the validation system for the BHV-1 safety of the products, a real-time PCR method was developed for quantitative detection of BHV-1 in raw materials, manufacturing processes, and final products as well as BHV-1 clearance validation. Specific primers for amplification of BHV-1 DNA was selected, and BHV-1 DNA was quantified by use of SYBR Green I. The sensitivity of the assay was calculated to be $2\;TCID_{50}/ml$. The real-time PCR method was validated to be reproducible and very specific to BHV-1. The established real-time PCR assay was successfully applied to the validation of Chinese hamster ovary (CHO) cell artificially infected with BHV-1. BHV-1 DNA could be quantified in CHO cell as well as culture supernatant. Also the real-time PCR assay could detect $10\;TCID_{50}/ml$ of BHV-1 artificially contaminated in bovine collagen. The overall results indicated that this rapid, specific, sensitive, and robust assay can be reliably used for quantitative detection of BHV-1 contamination during the manufacture of biologics.

To differentiate biliary atresia from intraheaptic cholestasis, Tc-99m DlSIDA hepatobiliary scintigraphies and percutaneous needle biopsies of 60 consecutive infants were evaluated retrospectively. Twenty three patients had biliary atresia and 37 patients intraheaptic cholestasis(neonatal hepatitis 34, TPN induced jaundice 2 and Dubin-Johnson syndrome 1). All sixty patients underwent Tc-99m DlSIDA hepatobiliary scintigraphy with phenobarbital pretreatment. Of 23 patients with biliary atresia, 22 were correctly interpreted showing 96% sensitivity while of 37 patients with intraheaptic cholestasis, only 12 had intestinal excretion of radionuclide showing 32% specificity. Among the forty needle biopsies, 17 of biliary atresia and 23 of intrahepatic cholestasis, 37 were correctly interpreted as either having biliary atresia or intrahepatic cholestasis. The overall diagnostic accuracy was 93%. Of 3 misdiagnosed cases, the histologic findings of two patients with biliary atresia(aged 43 days and 54 days at the first needle biopsy) were essentially the same as those of neonatal hepatitis. Follow-up biopsies, however, showed findings consistent with biliary atresia. The third one(VLBW premie with history of 8 weeks of TPN) showed mild ductal proliferation and portal fibrosis. This was interpreted as suspicious for biliary atresia. Jaundice resolved gradually. In summary, patients who have intestinal excretion of radionuclide on Tc-99m DlSIDA hepatobiliary scintigraphy, biliary atresia can be ruled out. But the patients who do not have intestinal excretion of radionuclide should have further investigation by needle biopsy. Judicious use of Tc-99m DISIDA hepatobiliary scintigraphy and percutaneous needle biopsy can give a diagnostic accuracy of 95% or more in cases of infantile cholestasis.
Cervical cancer is the fourth most frequently diagnosed cancer in women worldwide. In lower Human Development Index countries, it has the second highest incidence and mortality among cancer in women. Therefore, better diagnosis and treatment systems are needed. Among them, estrogen receptor alpha ($ER-{\alpha}$) mRNA expression has been analyzed with RT-qPCR since several studies reported that $ER-{\alpha}$ is necessary in the maturation of the uterus and is related to cervical cancer. In this study, $ER-{\alpha}$ quantitative analysis was performed on various lesions and normal tissue samples. Based on the receiver operating characteristic (ROC) curve, its sensitivity and specificity were 85% and 75%, respectively, showing higher or similar results to those of conventional HPV tests. In addition, its expression level was analyzed with clinical information. With regression analysis, the R square value between the $ER-{\alpha}$ mRNA expression level and menopause status was 0.5041, indicating a strong correlation. This study was performed as part of a pilot study and suggests that $ER-{\alpha}$ is related to carcinogenesis. Future studies will examine other hormones and menopausal factors with a larger sample size.

Purpose: Early detection of Mycoplasma pneumoniae is important for appropriate antimicrobial therapy in children with pneumonia. This study aimed to evaluate the diagnostic value of a rapid antigen test kit in detecting M. pneumoniae from respiratory specimens in children with lower respiratory tract infection (LRTI). Methods: A total of 215 nasopharyngeal aspirates (NPAs) were selected from a pool of NPAs that had been obtained from children admitted for LRTI from August 2010 to August 2018. The specimens had been tested for M. pneumoniae by culture and stored at $-70^{\circ}C$ until use. Tests with Ribotest $Mycoplasma^{(R)}$ were performed and interpreted independently by two investigators who were blinded to the culture results. Results: Among the 215 NPAs, 119 were culture positive for M. pneumoniae and 96 were culture negative. Of the culture-positive specimens, 74 (62.2%) were positive for M. pneumoniae by Ribotest $Mycoplasma^{(R)}$, and 92 of the 96 (95.8%) culture-negative specimens were negative for M. pneumoniae by Ribotest $Mycoplasma^{(R)}$. When culture was used as the standard test, the sensitivity and specificity of Ribotest $Mycoplasma^{(R)}$ were 62.2% and 95.8%, respectively. Additionally, the positive predictive value, negative predictive value, and overall agreement rates with Ribotest $Mycoplasma^{(R)}$ were 94.9%, 67.2%, and 77.2%, respectively. Conclusions: A positive test result of Ribotest $Mycoplasma^{(R)}$ suggests a high likelihood of culture-positive M. pneumoniae infection. However, a negative test result should be interpreted with caution because nearly one-third of negative test results reveal culture-positive M. pneumoniae infections.
The self-report assessment has been most commonly used to estimate bullying/victimization (B/V) rates in most domestic and international prevalence studies. However, the presence of many potential biasing factors in such an assessment method, including specific operationalization/measurement strategies and testing conditions, has become an issue due to a considerable variability in reported involvement rates across studies. This study analyzed self-reported B/V involvement rates on Olweus Bullying Questionnaire (OBQ) among 690 Korean middle school students by gender and two different cut-offs (generous vs. strict cut-offs) and examined if the involvement rates were significantly varied by testing conditions such as presentation vs. omission of a precise definition of B/V, anonymous vs. non-anonymous/confidential administration, and the use of global vs. specific questions. Chi-square analyses revealed that boys displayed higher involvement rates on global measures of B/V and on items related to direct forms of B/V, with no significant gender differences on specific measures of relational B/V rates. It was also found that a global rate of bullying and specific rates of verbal B/V were 111% to 157% higher when no definition was provided. However, anonymous vs. non-anonymous administration had no significant impacts on rates of involvement, except for one item; there were also no significant differences in reported degrees of frankness and perceived confidentiality of their responses across two adminstration conditions. Finally, when involvement rates were assessed by using specific vs. global items, they were 68% to 148% higher with binominal correlations in low to moderate ranges. Findings also indicated that global items had a high specificity but a relatively low sensitivity. Implications of these findings were fully discussed for researchers and practitioners in the field of B/V assessment.

Background : The plasma B-type natriuretic peptide(BNP) concentration increases with the degree of pulmonary hypertension in patients with chronic respiratory disease. The aim of this study was to examine the prognostic role of BNP in the acute exacerbation of chronic obstructive lung disease (COPD). Method : We selected 67 patients who were admitted our hospital because of an acute exacerbation of COPD. Their BNP levels were checked on admission at the Emergency Department. Their medical records were analyzed retrospectively. The patients were divided into two groups according to their in-hospital mortality. The patients' medical history, comobidity, exacerbation type, blood gas analysis, pulmonary function, APACHE II severity score and plasma BNP level were compared. Results : Multiple logistic regression analysis identified three independent predictors of mortality: $FEV_1$, APACHE II score and plasma BNP level. The decedents group showed a lower $FEV_1$($28{\pm}7$ vs. $37{\pm}15%$, p=0.005), a higher APACHE II score($22.4{\pm}6.1$ vs. $15.8{\pm}4.7$, p=0.000) and a higher BNP level ($201{\pm}116$ vs. $77{\pm}80pg/mL$, p=0.000) than the sSurvivors group. When the BNP cut-off level was set to 88pg/mL using the receiver operating characteristic curve, the sensitivity was 90% and the specificity was 75% in differentiating between the survivors and decedents. On Fisher's exact test, the odds ratio for mortality was 21.2 (95% CI 2.49 to 180.4) in the patients with a BNP level > 88pg/mL. Conclusion : The plasma BNP level might be a predictor of mortality in an acute exacerbation of COPD as well as the $FEV_1$ and APACHE II score.

Purpose: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. Materials and Methods: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of $^{99m}Tc$-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. Results: GBEF was significantly reduced in diabetes with autonomic neuropathy ($43{\pm}12.3%$) and without autonomic neuropathy ($57.5{\pm}13.2%$) compared with normal controls ($68{\pm}11.6%$, p<0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p<0.05). Fasting blood glucose level, age, sex, hemoglobin Alc, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. Conclusion: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.
