  • Objective : This study aimed to evaluate the relationship between comorbid obsessive compulsive disorder (OCD) and quality of life in stable patients with schizophrenia. Methods : We interviewed 162 symptom-stable inpatients who have been on a constant dose of antipsychotics for at least 3 months prior and diagnosed as chronic schizophrenia. Subsequently, patients were classified according to the existence of OCD as evaluated using the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). Further, all clinical and demographic data were collected and evaluated. To investigate potential interrelationships, the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Korea-Positive and Negative Symptom Scale (K-PANSS), Korean Modification of the Scale to Measure Subjective Well-Being under Neuroleptic Treatment (KmSWN) and Korean Version Quality of Life Scale (K-QOLS) were performed. Independent t-test and Chi-square test were used to compare groups and regression analysis was done to assess the relationship between the Y-BOCS and quality of life. Results : Schizophrenia patients with OCD showed significantly earlier onset of schizophrenia, more severe psychiatric symptoms and lower quality of life, compared to those without comorbid OCD. OCD might be associated with lower quality of life in schizophrenia. Conclusion : Schizophrenia patients with OCD showed lower quality of life than those without OCD. In the treatment for schizophrenia, evaluation of OCD might be needed to improve their quality of life and social function.

  • As genetic markers, single nucleotide polymorphisms (SNP) are very appropriate for the development of genetic tests for economic traits in livestock. Several microsatellite markers have been identified as useful markers for the genetic improvement of Hanwoo. Among those markers, ILSTS035 was recently mapped at a similar position with four SNPs (AH1_11, AH1_9, 31465_446, and 12273_165) in a linkage map of EST-based SNP in BAT6. Among the four SNPs, two SNPs (31465_446 and 12273_165) were analyzed using BLAST at the NCBI web site. The sequences including the 12273_165 SNP were identified at the intron region within the LOC534614 gene on the gene sequence map (Bos taurus NCBI Map view, build 3.1). The LOC534614 gene represents a protein similar to myosin heavy chain, fat skeletal muscle, embryonic isoform 1 in the dog, and myosin_1 (Myosin heavy chain D) in Macaca mulatta. In cattle, the myosin heavy chain was associated with muscle development. The phenotypic data for growth and carcass traits in the 415 animals were analyzed by the mixed ANCOVA (analysis of covariance) linear model using PROC GLM module in SAS v9.1. By the genotyping of Hanwoo individuals (n = 415) to evaluate the association of SNP with growth and carcass traits, it was shown that the 12273_165 SNP region within LOC534614 may be a candidate marker for growth. The results of the statistical analyses suggested that the genotype of the 12273_165 SNP significantly affected birth weight, weight of the cattle at 24 months of age, average daily gain and carcass cold weight (p<0.05). Consequently, the 12273_165 SNP polymorphisms at the LOC534614 gene may be associated with growth in Hanwoo, and functional validation of polymorphisms in LOC534614 should be performed in the future.

  • The purpose of the present study was designed to evaluate the bioequivalence of two ofloxacin tablets, Tarivid (Jeil Pharm. Co., Ltd.) and Favid (ILHWA Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty-four normal male volunteers, $23.67{\pm}3.12$ year in age and $68.50{\pm}7.23$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After four tablets containing 100 mg of ofloxacin were orally administered, blood was taken at predetermined time intervals and concentrations of ofloxacin in plasma were determined using HPLC. Pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$ and $C_{max}$ and untransformed $T_{max}$. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals for the log transformed data were acceptance range of log 0.8 to log 1.25 (e.g., $log0.94{\sim}log1.04\;and\;log0.90{\sim}log1.07\;for\;AUC_t\;and\;C_{max}$, respectively). The major parameters, $AUC_t$, and $C_{max}$, met the criteria of KDFA for bioequivalence indicating that Favid tablet is bioequivalent to Tarivid tablet.

  • The weighted sum of gray gas model(WSGGM) is applied to arbitrary mixtures of CO$_2$ and H$_2$0 gases. To evaluate this model, the spectral and total intensities are obtained for two different problem types. One has uniform, parabolic and boundary layer type temperature profiles with uniform partial pressure, and the other has nonuniform partial pressure and temperature profile. The results obtained from the two different problem types show fairly good agreements with the results obtained by the statistical narrow band model(SNB model) which is regarded as the reference solutions. The WSGGM and its data base provided by this study can be used for analysis of radiative transfer by combustion gases with different thermal loadings and chemical compositions.

  • The purpose of this study was to examine the effect of social support from teachers and friends on the career maturity of students at technical meister high schools. The Social Support Scale adjusted by Kim, Hye-Jin(2006) and the Career Maturity Attitude Inventory Scale produced by Lee, Ki-Hak(1997) were administered. The data from 194 were ultimately included to analyze. Corrlational coefficent and multiple regression analysis were performed using SPSS 21.0 statistical package. The results were as follows. First, perceived teachers' social support was higher than friends. Second, the effect of teachers' social support on career maturity was not significant but the effect of social support from friends was found. Among sub-factors of social support from friends, emotional and informative support were found significant effect on career maturity. The implication of these results were discussed in terms of career counseling and education of technical meister high schools.

  • The purpose of this study is to analyze the influence of the cash flow of pharmaceutical companies on R&D investment. 143 pharmaceutical companies listed in the KOSDAQ market from 2009 to 2013. Financial statements and comments in general and internal transactions were extracted from TS-2000 of the Korea Listed Company Association (KLCA), and data related to stock price was extracted from KISVALUE-III of NICE Information Service Co., Ltd. STATA 12.0 was used as the statistical package for panel analysis. The summary of the findings and the interpretation of the significance of this are as follows: First, the current ratio (internal finance) had a positive influence on R&D investment. Second, the debt ratio (external finance) had a negative influence on R&D investment. The pharmaceutical company prefers internal funds to external funds due to the asymmetry of information in the loan markets. In other words, this shows why internal finances have a significant influence on R&D investment at pharmaceutical companies.

  • Background: The evaluation of suitable reference genes as normalization controls is a prerequisite requirement for launching quantitative reverse transcription-PCR (RT-qPCR)-based expression study. In order to select the stable reference genes in abalone Haliotis discus hannai tissues (gill and hepatopancreas) under heavy metal exposure conditions (Cu, Zn, and Cd), 12 potential candidate housekeeping genes were subjected to expression stability based on the comprehensive ranking while integrating four different statistical algorithms (geNorm, NormFinder, BestKeeper, and ${\Delta}CT$ method). Results: Expression stability in the gill subset was determined as RPL7 > RPL8 > ACTB > RPL3 > PPIB > RPL7A > EF1A > RPL4 > GAPDH > RPL5 > UBE2 > B-TU. On the other hand, the ranking in the subset for hepatopancreas was RPL7 > RPL3 > RPL8 > ACTB > RPL4 > EF1A > RPL5 > RPL7A > B-TU > UBE2 > PPIB > GAPDH. The pairwise variation assessed by the geNorm program indicates that two reference genes could be sufficient for accurate normalization in both gill and hepatopancreas subsets. Overall, both gill and hepatopancreas subsets recommended ribosomal protein genes (particularly RPL7) as stable references, whereas traditional housekeepers such as ${\beta}-tubulin$ (B-TU) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) genes were ranked as unstable genes. The validation of reference gene selection was confirmed with the quantitative assay of MT transcripts. Conclusions: The present analysis showed the importance of validating reference genes with multiple algorithmic approaches to select genes that are truly stable. Our results indicate that expression stability of a given reference gene could not always have consensus across tissue types. The data from this study could be a good guide for the future design of RT-qPCR studies with respect to metal regulation/detoxification and other related physiologies in this abalone species.

  • Background : Review of readmissions in health care facilities is necessary from the viewpoint of both economic concerns and quality considerations. To identify the characteristics, factors, and causes of multiple admissions in comparison with single admissions is essential for both providers and payers in order to assure quality care and efficient use of medical resources. Methods: All discharges from an university hospital in 1993 were analyzed, and the characteristics of multiple admissions were identified and were compared with those of single admissions by using the data bases of the discharge abstract and billing for reimbursement. Medical records of patients readmitted within 6 days after the previous discharge were reviewed to identify the reasons for such prompt readmission. Statistical analysis between groups of patients were performed by using SPSS. Result : The mean age was higher in multiple admissions than those of single admissions, and the average length of stay was longer in multiple admissions than in single admissions. The hospital cost per day is higher in single admissions while the cost per case is higher in multiple admissions. More than half of readmissions occurred within one month after the preceding discharges. Above 15% of the readmission within 6 days after the preceding discharges seemed to have close relationship with quality of care provided during the preceding hospitalization. The death rate of the patients readmitted within 6 days was the highest in comparison with multiple admissions and single admissions. Conclusion : Potential preventable readmissions should be reduced by identifying characteristics of multiple admissions, especially unplanned readmission, and by applying some interventions such as standard predischarge assessment or careful follow-up care after discharge for high risk readmission groups. As the results of these efforts, health care facilities could achieve quality improvement in medical care, and effective use of hospital resources.
