박주연,여인권,Park, Ju-Yeon,Yeo, In-Kwon 한국통계학회 2009 응용통계연구 Vol.22 No.5

이 논문에서는 GARCH 모형에서 변환-역변환 방법을 통해 예측값을 추정할 때 발생하는 편향을 줄이기 위한 방법을 소개한다. 모수적 붓스트랩을 활용하여 본래 척도에서의 최소평균제곱오차 예측값인 조건부 기대값을 계산한다. KOSPI와 KOSDAQ 수익률 분석을 통해 제안한 방법이 편향을 줄여주는 것을 확인하였다. In this paper, we introduce the method that reduces the bias when the transformation and back-transformation approach is applied in GARCH models. A parametric bootstrap is employed to compute the conditional expectation which is the prediction value to minimize mean square errors in the original scale. Through the analyese of returns of KOSPI and KOSDAQ, we verified that the proposed method provides a bias-reduced estimation for the prediction value.

Purpose: This study was to identify factors influencing the quality of sleep in elderly women with urinary incontinence and examine the relationship among the factors. Methods: The study investigated 113 elderly women with urinary incontinence who were subject to the visiting care program at health centers in D-gu, D-si, South Korea. The collected data were analyzed using IBM SPSS version 19.0 along with ${\chi}^2-test$, t-test, ANOVA, Pearson's correlation, and multiple regression. Results: The total Pittsburgh Sleep Quality Index (PSQI) of the participants was found to be $11.41{\pm}4.34$. As a result of the correlation analysis, PSQI was found to have significant correlations with Female Lower Urinary Tract Symptoms (BFLUTS) (r= .32, p< .001). The Korean version of Physical Activity Scale for Elderly (K-PASE) was (r= -.34, p< .001) and the Geriatric Depression Scale Short Form (GDS-SF) was (r= .23, p= .012). Multiple regression analysis found sleeping pill use (${\beta}=-.35$, p< .001) had the strongest influence on PSQI, followed by physical activity (${\beta}=-.20$, p< .001), depression (${\beta}=.20$, p< .001), and lower urinary tract symptoms (${\beta}=.19$, p< .001). The total model explanatory power was 28.3% (F= 12.07, p< .001). Conclusion: The study findings are expected to be useful for enhanced understanding of the quality of sleep in elderly women with urinary incontinence.

Objective : We have explored the relationship between suicidal ideation and some very specific characteristics of the symptoms of depression and anxiety in Korean employees. Methods : During the period 2013 through 2014, 100,793 employees who visited the Health Screening Center were asked to complete questionnaires, including the Center for Epidemiologic Study-Depression scale (CSE-D), the Beck Anxiety Inventory (BAI) and the presence of suicidal ideation. We attempted to determine which specific subscale, of each the CES-D and BAI would be more closely related to suicidal ideation by different gender and age by logistic regression. Results : Depression has been found to be a more prevalent and predominant factor in suicidal ideation, when compared to the presence of the condition of anxiety. Of four subscales of CES-D, issues arising from interpersonal relationships were most often associated with suicidal ideation, regardless of the chronologic age or gender of the subject. In BAI, cognitive anxiety showed a more significant association with suicidal ideation than did somatic anxiety in our study participants, showing same pattern in different gender and age groups. Conclusions : Among subscales of CES-D and BAI, the interpersonal relationship in CES-D and cognitive anxiety in BAI showed a higher and more significant association with suicidal ideation in Korean employees.

The antimicrobial susceptibility, genotypes of enterotoxins(LT, STa) and pili(K88, 987P), and plasmid profiles were investigated with 102 Escherichia coli isolated from piglets showing diarrhea in Korea. Almost of them were susceptible to ceftiofur(99%), cefquinone(97.1%). However they showed resistance to bacitracin(100%), streptomycin(98%), vancomycin(97%), trimethoprim/sulfamethoxazole(87.2%), tetracycline(84.3%) in antimicrobial susceptibility test. Moreover, all of the isolates demonstrated resistance to more than 2, and 78% of them were resistant to more than 8 of total 17 drugs. Multiplex PCRs for genotyping of enterotoxins(LT, STa) and pili(K88, 987P) were established with primers designed based on sequences from Genebank. Seventeen strains(16.6%) of the isolates had STa gene, 11 strains(10.8%) of them had both STa and LT genes, and 18 strains(17.8%) had K88 gene. But none of the isolates harbored a gene exclusively encoding LT. The gene encoding 987P pili was not found in all isolates. Fifty-four strains of 102 isolates(52.9%) had plasmid with various sizes ranging from 125kb to 1.1kb. Numbers of plasmid per isolates were also various, from 1 to 9. Distinctive relationship between plasmid profiles and genotypes of enterotoxins and pili in the isolates was not found. These results might provide the basic knowledge to establish strategies for the treatment and prevention of colibacillosis in piglets.
