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.

본 연구의 목적은 문화예술패키지 구매경험, 예술전공, 콘서트 관람경험으로 요약되는 예술적 경험이 공연 패키지 구매의도에 미치는 영향력을 밝히는 것이다. 패키지 유형은 두 종류의 공연으로 결합된 동종패키지와 공연과 숙박권, 공연과 식사권으로 결합된 이종패키지로 구분하여 예술적 경험에 따라 구매의도에 미치는 상이한 영향력을 확인하였다. 분석결과 문화예술패키지 구매경험이 없는 경우 패키지 상품의 구매의도가 유의미하게 더 높았으며 동종패키지 중에서도 동일한 장르끼리 결합한 콘서트x콘서트 패키지의 구매의도가 더 높았다. 반면, 문화예술패키지 구매경험이 있는 경우 상이한 장르끼리 결합된 콘서트x클래식 패키지의 구매의도가 더 높은 것으로 나타났다. 또한 콘서트 관람경험이 있는 경우 이종패키지 중 콘서트x식사권 패키지의 구매의도가 더 높았으나 관람경험이 없는 경우 콘서트x숙박권 패키지의 구매의도가 더 높았다. 예술전공 여부에 따라서는 동종패키지와 이종패키지 간 구매의도에 유의미한 차이가 나타나지 않았으나 셀프패키지 구매의도에 대해서는 예술전공자가 동종패키지에 대해 더 긍정적인 태도를 보이는 것으로 나타났다. 본 연구결과는 번들링의 효과가 관객의 예술적 경험 여부에 따라 각기 상이하게 나타날 수 있음을 제시함으로써 문화예술기관에서는 이러한 점을 고려하여 최적의 번들링 구성을 고려해야 함을 시사하고 있다. The purpose of this study is to reveal the influence of art experience, which is summarized as experience in purchasing arts and cultural packages, major in art, and experience in watching concerts, on the intention of purchasing tickets for performance packages. Package types were divided into homogeneous packages and heterogeneous packages. A homogeneous package means a form that combines two types of performances, and a heterogeneous package means a form that is combined with performance and lodging vouchers, performance and meal vouchers, respectively. In this study, different influences on purchase intentions of the two packages were identified according to artistic experiences. As a result of the analysis, the purchase intention of the package product was significantly higher when there was no experience in purchasing the arts and cultural package, and the purchase intention of the concert×concert package was higher among the similar packages. On the other hand, it was found that the purchase intention of the concert×classical package combined with different genres was higher when there was experience in purchasing arts and cultural packages. In addition, the purchase intention of the concert×lodging voucher package among the heterogeneous packages was higher when there was experience in concert viewing, but the purchase intention of the concert×meal ticket package was higher when there was no viewing experience. There was no significant difference in purchase intention between the same type package and the heterogeneous package according to whether or not they majored in art, but it was found that art majors showed a more positive attitude toward the same type of package as to the intention to purchase self-packages. The result of this study suggests that the effect of bundling can appear differently depending on whether or not the audience has artistic experience, suggesting that culture and arts institutions should consider these points and consider the optimal bundling configuration.

주의력결핍-과잉행동장애(Attention deficit-hyperactivity disorder, ADHD)는 충동성, 과잉행동 등의 증상을 보이는 질환으로 유전적 요인의 역할에 대한 중요성이 주목받고 있다. 시상하부-뇌하수체-부신축(hypothalamus–pituitary–adrenal axis, HPA axis)의 활성도는 주의력결핍-과잉행동장애 환아의 스트레스반응에 영향을 미치는 것으로 보고되고 있으며, 이에 본 연구는 Corticotropin releasing hormone receptor 1 (CRHR1) 유전자의 유전자다형성 rs110402와 ADHD의 관련성을 파악해보고자한다. 대상자는 실험군으로 ADHD 환아(107명)를, 정상 대조군으로 정상 신생아(106명)를 대상으로 하였으며, ADHD 환아군과 정상대조군에서 CRHR1 유전자다형성 rs110402의 대립유전자 및 유전자형을 분석하였다. 연구 결과, ADHD 환아군과 정상대조군은 유전자형, 대립유전자의 분포에서 유의한 차이를 나타냈다. 본 연구의 결과는 CRHR1 유전자의 유전자 다형성이 한국인 ADHD의 원인이 될 수 있는 후보유전자로서의 가능성을 제시하였다. Attention deficit hyperactivity disorder (ADHD) is known to be associated with a variety of risk factors, such as personal characteristics, psychosocial, neurologic, and physiological factor. Few studies have examined the genetic factors related to ADHD. In recent studies, ADHD may be associated to hypothalamus–pituitary–adrenal axis (HPA axis) activity. Corticotropin releasing hormone receptor 1 (CRHR1) gene is an important regulator of system of the HPA axis, we selected CRHR1 gene (rs110402) as candidated gene for ADHD. 107 ADHD patients and 106 normal newborns were used as frozen DNA. For analysis, CRHR1 (rs110402) gene was genotyped by Single strand conformation polymorphism analysis (SSCP). The genotype and allele distribution of CRHR1 (rs110402) gene polymorphism in ADHD group and normal control group were analyzed. As a result, ADHD and CRHR1 gene polymorphism showed significant differences in genotype and allele distribution. Plymorphism of CRHR1 may play an importatn role in ADHD in the Korean.

Preferential concentration is a well-known phenomenon that clusters of particles (Stokes number around 1.0) exhibits the discernible concentration at the positions with a higher strain rate. We experimentally study upward particle-laden jet flows with a horizontal crossflow, while varying the velocity ratio between jet and crossflow, and particle Stokes number (0.01 - 27.4). For each case, the single-phase jet flow is measured with a particle image velocimetry. Particle (Silicon, 6 - 206 um in size) distributions are also optically measured separately, which is further quantified using Voronoi diagram analysis and planar nephelometry, which are modified to be applied to the optically obtained particle images. It is found that the clusters are dependent on Stokes number as well as particle Reynolds number, and solid fraction. Furthermore, we develop cluster concentration models that explain where the preferential concentration is found. More discussions on the particle dispersion will be provided.

A device that consists of an array of hydrofoils (called a vane deployer) is widely used in ocean engineering. In general, the vane deployer has to spread out efficiently, which is possible by enhancing the lift-to-drag ratio. In the present study, using a computational fluid dynamics, we investigate the effect of hydrofoil arrangement on the lift-to-drag ratio to establish the condition in which a reasonable level of constant lift-to-drag ratio is achieved in a wide range of angle of attack, to avoid a degradation of the hydrodynamic performance. First, the flow around two-dimensional hydrofoil array is examined by varying the size of hydrofoil components, gap between the hydrofoils, and arrangement type. As a result, we determine the optimized hydrofoil array configuration whose lift-to-drag ratio is nearly independent on the angle of attack. Finally, a three-dimensional simulation is performed for the optimized geometry to estimate the performance of actual vane deployer.
