본 연구의 목적은 보건교사의 교사효능감, 전문성 지향성, 교사헌신 간 관계에서 전문성 지향성의 매개효과를 확인하기 위함이다. 연구대상은 G시에 위치한 초·중등학교에서 근무 중인 보건교사 159명이며 교사효능감, 교사헌신, 전문성 지향성 척도를 사용하여 자료를 수집하였다. 자료분석은 SPSS 21.0를 사용하여 기술분석과 상관분석을 실시하였으며 PROCESS Macro를 사용하여 교사헌신과 교사효능감의 관계에서 전문성 지향성의 매개효과의 유의성을 검증하였다. 연구 결과를 보면, 보건교사의 교사효능감과 교사헌신의 관계에서 전문성 지향성이 부분매개변인으로 영향력을 증가시키는 것으로 확인되었다. 결론적으로 보건교사의 교사헌신 향상을 위해서 교사효능감과 전문성 지향성이 중요한 변인임을 밝히는 데 의의가 있다. 나아가 보건교사의 교사효능감, 교사헌신, 전문성 지향성을 향상시킬 수 있는 여러 지원방안이 모색될 필요가 있음을 시사한다. This study was conducted to examine the mediating effect of professional orientation in the relationship between teacher efficacy and teacher commitment in health teachers. The subjects of this study were 159 health teachers working in schools located in G city. Data were collected using teacher efficacy, teacher commitment, and professional-orientation scales. SPSS 21.0 was used to conduct descriptive analysis and correlational analysis. PROCESS Macro was also conducted to verify the mediation effect of professional orientation. This study found that the relationship between health teachers' teacher efficacy and teacher commitment was partially mediated by their professional orientation. This study provided several implications and suggestions to improve health teacher's efficacy, teacher commitment and professional orientation for their professional development.

Objective-This study aimed to examine the associations between depression and both coronary artery disease (CAD) and cardiovascular risk factors (CVRs) in Korean women. Furthermore, this study sought to determine whether depression was associated with use of healthcare services in women with CAD or CVRs. Methods-This cross-sectional study was conducted on 26,335 women who were aged 19 years or older, and who participated in the Korean National Health and Nutrition Examination Survey (2007-2014). Associations of prior diagnosis of depression with CAD and CVRs and with nonutilization of healthcare services were investigated. Results-Women with depression had a higher prevalence of CAD and CVRs including obesity, hypertension, dyslipidemia, and metabolic syndrome than those without depression. In addition, depression was significantly associated with nonutilization of healthcare services in women with most CVRs. Conclusion-Considering the high rate of comorbid depression with CAD or CVRs and the low levels of health service utilization in depressed patients, screening for common CVRs, such as obesity, hypertension, and dyslipidemia, should be provided for patients with depression in mental health care settings.
Virtualizing Graphics Architecture of Android Mobile Platforms in KVM/ARM Environment

<P>With the availability of virtualization extension in mobile processors, e.g. ARM Cortex A-15, multiple virtual execution domains are efficiently supported in a mobile platform. Each execution domain requires high-performance graphics services for full-featured user interfaces such as smooth scrolling, background image blurring, and 3D images. However, graphics service is hard to be virtualized because multiple service components (e.g. ION and Fence) are involved. Moreover, the complexity of Graphical Processing Unit (GPU) device driver also makes harder virtualizing graphics service. In this paper, we propose a technique to virtualize the graphics architecture of Android mobile platform in KVM/ARM environment. The Android graphics architecture relies on underlying Linux kernel services such as the frame buffer memory allocator ION, the buffer synchronization service Fence, GPU device driver, and the display synchronization service VSync. These kernel services are provided as device files in Linux kernel. Our approach is to para-virtualize these device files based on a split device driver model. A major challenge is to translate guest-view of information into host-view of information, e.g. memory address translation, file descriptor management, and GPU Memory Management Unit (MMU) manipulation. The experimental results show that the proposed graphics virtualization technique achieved almost 84%-100% performance of native applications.</P>

본 연구에서는 수면 행동 개선에 도움을 주는 관계형 에이전트 ‘꿀잠이’를 개발해 이에 대한 효과를 검증하였다. 특히, 관계형 에이전트 ‘꿀잠이’와 상호작용을 통해 수면 습관 행동에 대한 상호작용 디자인을 대상체의 형상화와 맞춤형 메시지를 바탕으로 설계하고 인사이트를 확보하였다. 사용자들은 수면 습관 문제에 직간접적인 영향이 있는 다양한 데이터를 대화과정에서 자연스럽게 기록함으로써 수면에 대한 습관을 판단하고 스스로 제어하려는 노력을 기울일 수 있게 되었다.

Objective: To determine whether various immune-related proteins in cervicovaginal fluid (CVF), alone or in combination with clinical risk factors, can predict intra-amniotic infection and/or inflammation (IAI) in women with preterm premature rupture of membranes (PPROM) and to compare predictive ability of these biomarkers with that of amniotic fluid (AF) white blood cell (WBC) using invasive amniocentesis. Methods: This retrospective cohort study included 99 consecutive singleton pregnant women (23.0-33.6 gestational weeks) with PPROM who underwent amniocentesis. The amniotic fluid (AF) was cultured, and the white blood cell (WBC) count was determined. The stored CVF samples were assayed for complement C3a and C5a, TIMP-1, MMP-9, and M-CSF by using ELISA kits. Serum C-reactive protein (CRP) level was measured at the time of sampling. The primary outcome measures were IAI [defined as a positive AF culture and/or an elevated AF IL-6 level (2.6 ng/mL)]. Results: The overall prevalence of IAI was 50.5% (50/99). The CVF levels of C3a, C5a, TIMP-1, MMP-9, and M-CSF were significantly higher in women with IAI. The women with IAI had a significantly lower gestational age at sampling and a higher level of serum CRP. Using a stepwise regression analysis, a combined prediction model was developed, which included the CVF MMP-9 and serum CRP [area under the curve (AUC), 0.827]. The AUC for this model was significantly higher than either parameter retained in this model, but no differences were observed between the AUC of this model based on non-invasive variables, and AF WBC. Conclusion: This study suggests that TIMP-1, MMP-9, M-CSF, C3a and C5a in the CVF may be useful as new non-invasive predictors of IAI in women with PPROM and that the best predictive model, which combined these biomarkers with conventional clinical factors, can significantly improve the predictability for IAI.

Gluten-free rice udon (GFU) was prepared with rice flour and acetylated distacrch adipate at optimized mixing ratio based on previous study. The quality parameters such as pH, moisture content, texture, color value and microbiological analysis of GFU were investigated during storage at 4℃ (GFU4) and 25℃ (GFU25) temperature for 3 days. The results showed that GFU stored at both temperatures, there was a decrease in moisture content, pH and redness at the end of storage. However, the lightness of GFU4 decreased while increased in GFU25 sample. Except the springiness in texture, all the values increased in GFU4 and GFU25 during storage. There was no significant difference in cohesiveness of GFU. TPC (total plate count) of GFU4 and remained stable at around 3.30 log CFU/mL during storage time. On the other hand, GFU25 showed a rapid increase in TPC to 6.15 log CFU/mL until the end of storage. This proved that storage at 4℃ was provided storage stability of GFU compared with 25℃, and further research should be conducted to extend the shelf life of GFU at 4°C.
