This study was designed to investigate organizational culture and emotional intelligence as predictors of job performance among library personnel in Edo state, Nigeria. The survey research design was employed for the study with a population size of 181 library personnel in the 15 academic libraries under study, and due to the manageable population size, total enumeration was adopted as the sampling technique. The questionnaire was used to elicit data from the respondents. Of the 181 copies of the questionnaire administered, 163 copies were retrieved and found valid for analysis constituting a 90% response rate. Four research questions and four null hypotheses (tested at 0.05 level of significance) were formulated to guide the study. The tool used to analyze the research question was descriptive statistics (percentage, mean, and standard deviation) and inferential statistics (correlation and multiple regression) for testing the hypotheses. The findings of the study revealed that there is a high level of job performance, good organizational culture, and high level of emotional intelligence among the personnel. Organizational culture and emotional intelligence jointly and significantly predict job performance of personnel. There is significant positive correlation between organizational culture and job performance. The linear combination of emotional intelligence and organizational culture predict job performance of library personnel in the academic libraries under study. The research concludes that there is a need for high job performance in libraries which is predicted by the organizational culture of the library and the level of emotional intelligence of the library personnel.

자동차 보유대수 증가에 따른 교통 혼잡과 대기오염 및 에너지 과다사용 문제를 극복하기 위해 녹색교통수단인 자전거이용의 중요성이 현저하게 대두되고 있지만, 부산시는 지형적 특성과 대중교통 접근성의 한계 등으로 인해 자전거 이용률이 상대적으로 낮은 실정이다. 따라서 지리적 여건과 이용활성화를 고려한 자전거도로의 노선선정이 이루어져야 할 것이다. 본 연구는 계층분석법(AHP)을 이용하여 노선선정 인자의 가중치를 산정하고, GIS 소프트웨어를 이용하여 데이터베이스를 구축한 뒤, 산정된 가중치를 적용하여 노선을 도출하였다. GIS 기반에서 AHP 분석을 수행한 결과, 조사의 일관성을 검증함으로써 신뢰성 있는 자료를 얻을 수 있었고 임의로 선정된 노선보다 이용수요가 많은 곳으로 노선이 도출되었다. 따라서 향후 지역의 특수성을 반영한 노선선정이나 투자 우선순위 결정 등에 본 연구가 활용될 것으로 기대된다.

Background: Malignant lymphoma is the most common hematopoietic malignancy in dogs, and relapse is frequently seen despite aggressive initial treatment. In order for the treatment of these recurrent lymphomas in dogs to be effective, it is important to choose a personalized and sensitive anticancer agent. To provide a reliable tool for drug development and for personalized cancer therapy, it is critical to maintain key characteristics of the original tumor. Objectives: In this study, we established a model of hybrid tumor/stromal spheroids and investigated the association between canine lymphoma cell line (GL-1) and canine lymph node (LN)-derived stromal cells (SCs). Methods: A hybrid spheroid model consisting of GL-1 cells and LN-derived SC was created using ultra low attachment plate. The relationship between SCs and tumor cells (TCs) was investigated using a coculture system. Results: TCs cocultured with SCs were found to have significantly upregulated multidrug resistance genes, such as P-qp, MRP1, and BCRP, compared with TC monocultures. Additionally, it was revealed that coculture with SCs reduced doxorubicin-induced apoptosis and G2/M cell cycle arrest of GL-1 cells. Conclusions: SCs upregulated multidrug resistance genes in TCs and influenced apoptosis and the cell cycle of TCs in the presence of anticancer drugs. This study revealed that understanding the interaction between the tumor microenvironment and TCs is essential in designing experimental approaches to personalized medicine and to predict the effect of drugs.

Background: The number of synthesized chemicals has rapidly increased over the past decade. For many chemicals, there is a lack of information on toxicity. With the current movement toward reducing animal testing, the use of toxicity big data and deep learning could be a promising tool to screen potential toxicants. Objectives: This study identified potential chemicals related to reproductive and estrogen receptor (ER)-mediated toxicities for 1135 cleaning products and 886 laundry products. Methods: We listed chemicals contained in cleaning and laundry products from a publicly available database. Then, chemicals that potentially exhibited reproductive and ER-mediated toxicities were identified using the European Union Classification, Labeling and Packaging classification and ToxCast database, respectively. For chemicals absent from the ToxCast database, ER activity was predicted using deep learning models. Results: Among the 783 listed chemicals, there were 53 with potential reproductive toxicity and 310 with potential ER-mediated toxicity. Among the 473 chemicals not tested with ToxCast assays, deep learning models indicated that 42 chemicals exhibited ER-mediated toxicity. A total of 13 chemicals were identified as causing reproductive toxicity by reacting with the ER. Conclusions: We demonstrated a screening method to identify potential chemicals related to reproductive and ER-mediated toxicities utilizing chemical toxicity big data and deep learning. Integrating toxicity data from in vivo, in vitro, and deep learning models may contribute to screening chemicals in consumer products.

Background: Sickness absenteeism is an area of concern in nursing and is more concerning given the recent impacts of the COVID-19 pandemic on healthcare. This study is one of two meta-analyses that examined sickness absenteeism in nursing. In this study, we examined demographic, lifestyle, and physical health predictors. Methods: We reviewed five databases (CINAHL, ProQuest Allied, ProQuest database theses, PsycINFO, and PubMed) for our search. We registered the systematic review (CRD de-identified) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Additionally, we used the Population/Intervention/Comparison/Outcome Tool to improve our searches. Results: Following quality testing, 17 articles were used for quantitative synthesis. Female employees were at higher risks of sickness absenteeism than their male counterparts (OR = 1.73; 95% CI: 1.33-2.25). Nursing staff who rated their health as poor had a greater likelihood of experiencing sickness absence (OR = 1.38; 95% CI: 1.19-1.60). Also, previous sick leave predicted future leaves (OR = 3.35; 95% CI: 1.37-8.19). Moreover, experiencing musculoskeletal pain (OR = 2.41 95% CI: 1.77-3.27) increased the likelihood of sickness absence with greater odds when it is a back pain (OR = 3.05; 95% CI: 1.66-5.62). Increased age, physical activity, and sleep were not associated with sick leave. Conclusion: Several variables were statistically associated with the occurrence of sickness absenteeism. One primary concern is the limited research in this area despite alarming rates of sick leave in healthcare. More research is required to identify predictors of sickness absence, and thereby, implement preventative measures.

Objectives : The purpose of this study is to review clinical studies about the effect of chuna manual therapy (CMT) for peripheral facial paralysis in children. Methods : In this review, we searched 11 electronic databases (Pubmed, Cochrane Library, EMBASE, CINAHL, CAJ, Oasis, NDSL, KISS, RISS, KISTI, Dbpia); We concluded our literature search in April 23, 2019. We included only randomized controlled trials (RCTs) of testing CMT for peripheral facial paralysis in children. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. The meta-analysis was performed by synthesizing outcome data of total efficacy rate (TER). Results : After screening papers, a total of 6 RCTs were selected and analyzed. In the 6 RCTs, patients(n=15-60 per study) were randomized into groups for treatment and control. Specifically, the treatment group received CMT, while the control group was concurrently given usual care, such as acupuncture and medicine. The meta-analysis showed that the treatment group receiving CMT alone showed significant improvement in TER, compared to the control group receiving acupuncture therapy alone(P<0.05). And the treatment group receiving CMT combined with usual care showed positive results, in terms of TER, compared to the control group receiving usual care, but was not statistically significant(P>0.05). Conclusions : Our analysis suggests that CMT has therapeutic effects for peripheral facial paralysis in children. However, to confirm this result, further investigation accompanied by high quality studies is required.

Background: The Microsoft Kinect which is a low-cost gaming device has been studied as a promise clinical gait analysis tool having satisfactory reliability and validity. However, its accuracy is only guaranteed when it is properly positioned in front of a subject. Objects: The purpose of this study was to identify the error when the Kinect was positioned at a $45^{\circ}$ angle to the longitudinal walking plane compare with those when the Kinect was positioned in front of a subject. Methods: Sixteen healthy adults performed two testing sessions consisting of walking toward and $45^{\circ}$ obliquely the Kinect. Spatiotemporal outcome measures related to stride length, stride time, step length, step time and walking speed were examined. To assess the error between Kinect and 3D motion analysis systems, mean absolute errors (MAE) were determined and compared. Results: MAE of stride length, stride time, step time and walking speed when the Kinect set in front of subjects were investigated as .36, .04, .20 and .32 respectively. MAE of those when the Kinect placed obliquely were investigated as .67, .09, .37, and .58 respectively. There were significant differences in spatiotemporal outcomes between the two conditions. Conclusion: Based on our study experience, positioning the Kinect directly in front of the person walking towards it provides the optimal spatiotemporal data. Therefore, we concluded that the Kinect should be placed carefully and adequately in clinical settings.

Objectives: The purpose of this study was to assess the effects of moxibustion treatment for Cardiac arrhythmia through a systematic review. Methods: Electronic database including Cochrane library, Pubmed, China National Knowledge Infrastructure, Embase, DBpia, and Korean studies Information Service System were searched by combining the keywords such as "arrhythmias", "cardiac arrhythmias", "心律失常", "moxibustion" and "艾灸". Through the searching, 5 randomized controlled trials(RCTs) were included except animal testing and cellular experiment etc. The quality of each RCTs was assessed using the Cochrane risk of bias tool. Results: We included 5RCTs involving 468 participants. Two RCTs compared moxibustion versus conventional treatment, another RCT compared moxibustion plus acupuncture versus conventional treatment, another RCT compared moxibustion plus herbal medicine verus conventional treatment, the other RCT compared moxibustion plus herbal medicine and ointment versus conventional treatment. These studies were evaluated by the efficacy rate of treatments. Studies measured outcomes in efficacy, heart rate, electrocardiogram and symptoms. Each of 5 trials statistically showed a significant differences in efficacy rate. One study reported about side effects and another study reported about complications. The overall risk of bias was unclear in 5 studies. Conclusions: The evidence suggests that moxibustion treatment may help to reduce cardiac arrhythmia, however, it is limited, low-certainty and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.
