Background/Aims: We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease. Methods: Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs negative; n=18), B (anti-HBc positive, anti-HBs positive; n=34), and C (anti-HBc negative, anti-HBs positive/negative; n=19), and by anti-HCV positivity (anti-HCV positive; n=32 vs. anti-HCV negative; n=39). Liver biopsy samples were taken, and HBV DNA was quantified by real-time PCR. Results: Intrahepatic HBV DNA was detected in 32.4% (23/71) of the entire cohort, and HBV DNA levels were invariably low in the different groups. Occult HBV infection was detected more frequently in the anti-HBc-positive patients. Intrahepatic HBV DNA was detected in 28.1% (9/32) of the anti-HCV-positive and 35.9% (14/39) of the anti-HCV-negative subjects. The HCV genotype did not affect the detection rate of intrahepatic HBV DNA. In anti-HCV-positive cases, occult HBV infection did not affect liver disease severity. Conclusions: Low levels of intrahepatic HBV DNA were detected frequently in both HBsAg-negative and anti-HCV-positive cases. However, the frequency of occult HBV infection was not affected by the presence of hepatitis C, and occult HBV infection did not have a significant effect on the disease severity of hepatitis C.

광주광역시 근대건축물의 건축적 특성에 관한 조사연구 : 현존 근대건축물을 중심으로 Focused on the remained modern architecture

김진안,탁형수,천득염 대한건축학회 2003 대한건축학회논문집 Vol.19 No.11

The existing studies about buildings during modern period, from the Japanese annexation of Korea to the Liberation, are limited around Seoul and major port cities like In-chon and Pu-san. It has to be made sure that architectural development of circumstance at a small or middle-scale city should be simultaneously examined. The purpose of this study is that the materials, which could historically prosepect architectural activities of the times, should be sorted out by examining and discovering modern buildings before they are destroyed, and the opportunity to newie regards modern buildings as a cultural heritage should be constituted.

金光華,김종,한민철,정평유,한천구 대한건축학회 2004 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.24 No.1(구조계)

The objective of this paper is to investigate the physical and mechanical properties of concrete incorporating shrinkage reducing admixture(SRA) and mineral admixture(MA) such as fly ash and blast furnace slag powder. According to results, for fresh concrete properties, increase of SRA content leaded to reduce the fluidity and air content sharply. For setting time, use of SRA caused concrete to accelerate setting time, and compared with plain concrete it retarded by incorporating MA. Compressive strength decreased with an increase in SRA content, and when incorporating MA, compared with plain concrete, it shows lower compressive strength in early age but similar or increase by the elapse of age due to the pozzolanic and latent hydration reaction. For drying shrinkage, concrete shows decline tendency with an increase in SRA content due to the relaxation effect at the capillary tension in concrete by SRA. In the scope of this paper, it is found that the use of SRA with 1.0% has optimum effects on the various properties of concrete, and the combinations of SRA and fly ash will ensure the stability for drying shrinkage.

金光華,김기정,이문환,이세현,한천구 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2(구조계)

This study is intended to investigate the fundamental properties of cement mortar with solid content and leaving time of recycled water that stabilizing agent is added. According to the results, fluidity and air content does not make a big difference with variation of solid content. As the leaving time of recycled water is long, fluidity and air content increases. Setting time is shortened due to fine particle with an increase of solid content and leaving time. Compressive strength and flexural strength increase with an increase of solid content, and they increase at the leaving time of 1 day, but decrease after 2days. Length change by drying shrinkage is smaller than that of plain concrete, and is almost same with variation of solid content. And it is reduced at the leaving time of 1 day, but increases after that. Therefore, it analyzed that the effect of stabilizing agent is best under condition of adding ratio of 0.15%, solid content of 3% and leaving time of 1day, and it also works upto solid content of 5% and leaving time of 2days.

한국판 소아 양극성장애 설문지 2.0(Child Bipolar Questionnaire 2.0)의 신뢰도 및 타당도 연구

천근아,신동원,김보라,소윤섭,전진용,송동호 大韓神經精神醫學會 2008 신경정신의학 Vol.47 No.3

Objectives : The Child Bipolar Questionnaire 2.0 (CBQ 2.0) is a rapid screener with a Core Index subscale of symptom dimensions frequently reported in childhood-onset bipolar disorder (BD) and scoring algorithms for DSM-Ⅳ BD, with and without ADHD, and the proposed Narrow, Broad, and Core phenotypes. This report provides preliminary data on the reliability and validity of the CBQ 2.0-Korean version. Methods : Core Index subscale to effectively predict diagnostic classification by structured interview was assessed using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K). Test-retest and inter-rater reliabilities of the CBQ 2.0 were assessed. Correlation of Korean Child Behavior Checklist (K-CBCL) with CBQ 2.0-Korean version was performed. Results : The CBQ 2.0 screening algorithms performed with a specificity of 66.7% and a sensitivity of 94.7% in classifying subjects with K-SADS-PL-K diagnosis of BD vs. no BD. The Core Index subscale had “good” agreement with K-SADS-PL-K diagnosis (Kappa=0.676) in identifying BD, ADHD-only, and no diagnosis. Conclusion : This preliminary data is from a sample derived from the child and adolescent psychiatric clinics, further validation is needed with community based samples in which childhood-onset BD is rarer and diagnoses more diverse. The CBQ 2.0-Korean version shows potential for rapid and economically feasible identification of possible childhood-onset BD cases as defined by DSM-Ⅳ criteria as well as by alternate disease phenotypes.

The present study was designed to examine the effect of performance outcomes on attributional patterns across male boxers in the athletic setting. Boxers reported causal attributions on the 4-itemed 7-point Attribution-success Scale and 4-itemed 7-point Attributions on the 4-itemed 7-point Attribution-Success Scale and 4-itemed 7-point Attribution-Failure Scale by Carrots(1981). The relationship between the two kinds of variables were examined by pearson's and two-way ANOVA. The implcations of the study are as follows: 1. The outcome performance boxers significntly affected their ability attribution. The mean ability attribution scale scores for the winners was significantly higher than that of losers. 2. The outcome performance boxers significntly affected their effort attribution. The mean effort attribution scale scores for the winners was significantly higher than that of losers. 3. The outcome performance boxers significntly affected their luck attribution. The mean luck attribution scale scores for the winers was significantly lower than that of losers. 4. The outcome performance boxers significntly affected their task difficulty attribution. The mean task difficulty attribution scale scores for the winners was significantly lower than that of losers. In conclusion, winners perceived the causes behind the successful outcome to be more controllable trait.

한국어 종성 폐쇄음 /k^ㄱ/,/t^ㄱ/,/p^ㄱ/의 음향 음성학적 연구

김병천,梁鎭宇 안성산업대학교 1994 論文集 Vol.26 No.-

본 논문은 한국어의 종성 폐쇄음 /k^ㄱ/,/t^ㄱ/,/p^ㄱ/에 대한 음향 음성학적인 분석에 관한 연이다. 본 논문에서는 세 개의 종성 폐쇄음 /k^ㄱ/,/t^ㄱ/,/p^ㄱ/이 8개의 단모음(ㅏ,ㅓ,ㅗ,ㅜ,ㅡ,ㅣ,ㅐ,ㅔ)과 조합되어 형성된 24개의 음절을 선택하여 3인의 성인 남성이 각각 3회씩 발음하여 구성한 216개의 음성 데이터를 사용하여 포만트 주파수를 추출한 연후에 각각의 모음에 대해 종성 폐쇄음의 포만트 주파수가 이동하는 방향을 분석하였다. 실험 걸과 모음에서 종성 폐쇄음으로 이동하는 과도 구간의 최종 포르만트 주파수는 각 모음마다 상당한 차이를 내었으며, 과도 구간에서 각 모음에 따라 각기 다르다는 것을 알 수 있었다. This paper is a study on the acoustic-phonetical analysis of Korean final stops /k^ㄱ/,/t^ㄱ/,/p^ㄱ/. In this paper, I selected twenty four syllables in order to constitute corpora. These syllables are formed by combination of three final stops /k^ㄱ/,/t^ㄱ/,/p^ㄱ/ and eight single vowels /a/,/∂/,/o/,/u/,/?/,/i/,/æ/,/ε/. Three adult men pronounced these corpora three times a man and stored them files. After extraction of the final stop's frequencies from the stored files, I analysed the moving directions of the final stop's final formant frequencies for each vowel. As a result of the analysis, I was able to confirm that the final formant frequencies of transition section moving from the vowels to the final stops were very different for each vowel, and the features of each formant frequencies.

酒精依存에서 血漿 Dopamine 및 Serotonin 濃度 變化의 意味

田珍淑,金玹壽,吳秉勳 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.3

Dopamine and serotonin drew much attention to understand a biological mechanism underlying alchohol dependence. There were three reasons. Frit, behavioral effects governed by them were quite similar with various psychopathology observed in alcoholism. Second, preference to alcohol drinking tended to be related to the genetically transmitted biochemical abnormalities of these neurotransmitters. Finally, reward-mediating brain areas which seemed to be related to alcoholism were include in dopaminergic and serotonergic pathways. The aims of this study were to look for any changes of dopamine and serotonin concentrations in alcohol dependence, to identify what psychopathology was associated with, and to understand a biological mechanisms underlying alcohol-related psychopathology. Subjects were consisted of 25 male patients admitted with alcohol dependence and 25 healthy male volunteers. Samples drawn after 1 to 3 weeks of detoxification were analyzed by HPLC for the measurement of plasma dopamine and serotonin concentrations. Otherwise, precise alcohol history including duration of alcohol drinking, onset age, family history, types of alcoholism, MAST score, and frequency of hospitalization was done. Furthermore, psychopathology was rated by several questionnares like BPRS, MMPI, Sexual Jealousy Questionnaire, BDI and CES-D. 1) Mean concentration of dopamine in alcoholics(61.8±22.6pg/ml) was significantly(p<0.01) lower than in controls(77.4±16.3pg/ml), while serotonin concentration in alcoholics tended to be higher than in controls. 2) Dopamine concentration was negatively correlated with 'hallucinatory behavior' item(p<0.01) and 'unusual thought content' item(p<0.01) of BPRS, and 'hypochondriasis' scale(p<0.05) of MMPI. While serotonin concentration was positively correlated with 'tension' item(p<0.001) of BPRS. 3) Dopamine concentration was negatively correlated with SJQ(p<0.05), while serotonin concentration was positively correlated with frequency of hospitalization(p<0.05) and total score of BPRS(p<0.001). In conclusion, reduced dopamine and increased serotonin concentrations seemed to be associated with psychosis developed in alcohol dependence. Otherwise, impulsivity-aggressivity easily found in alcoholics might be biologically related to decreased dopamine concentration.
