It is well known that the most common sites for venous access are the superficial veins of the upper limb, particularly dorsal metacarpal veins and median cubital vein. Although dorsal metacarpal veins are the first choice for venous cannulation, there is scarce information about their anatomic variation. Hence, detailed anatomical information about these veins will improve the anatomic knowledge of the health care providers. Subsequently, this study was designed to study the dorsal metacarpal veins and to determine the most prominent dorsal metacarpal vein. A cross sectional study of 402 subjects (804 hands), was prepared to study the superficial veins on the dorsum of the hand among Jordanian students and staff of one of the major governmental medical colleges in Jordan, by using infrared illumination system. The obtained data was analyzed according to sex, sidedness, and handedness. Six locations of the most prominent dorsal metacarpal veins were identified. There was a significant relation between both females and males and the most prominent dorsal metacarpal vein (P=0.01). For the first time this study identified the most common location of the most prominent dorsal metacarpal vein in the fourth intermetacarpal space.

Purpose: To determine whether smoking status (active/passive) affects recurrence events after breast cancer (BC) diagnosis among women. Methods: A comprehensive literature search of MEDLINE, Cochrane Central, EMBASE, and Web of Science databases on smoking status and BC outcomes retrieved 5,940 articles. After reviewing the inclusion and exclusion criteria, we selected 14 articles for a full review and synthesis. Results: Five studies were cohort retrospective, 6 were case-control, 2 were prospective cohort studies, and 1 was a secondary analysis of a randomized control trial. Among the 8 articles that focused on active smoking, 6 showed an increased risk of BC recurrence, and 2 showed no evidence of such an association. Studies that examined former smokers found little evidence of an increased risk of BC recurrence. This association may be dose-dependent. Conclusion: Given the current evidence, although limited, active smokers should quit smoking after BC diagnosis as trends indicate a positive association between active smoking and BC recurrence. More robust evidence is needed to assess such associations and examine the outcomes of quitting smoking in such patients.

Tobacco bacterial wilt caused by Ralstonia solanacearum invades tobacco plants during the whole growth period afecting yield and quality. However, the transcriptome profling of tobacco plant in response to bacterial wilt has not been well studied. In this study, we identifed the transcriptional profles of bacterial wilt-resistant (ac Yanyan97) and -susceptible (ac Honghuadajinyuan) tobacco cultivars infected with R. solanacearum at six time points by RNA sequencing. Gene expression analysis showed that the resistant cultivar manifested a faster change in the expression of defense-related genes than the susceptible cultivar during R. solanacearum infection, by which more diferentially expressed genes (DEGs) were up-regulated rather than down-regulated at all time points. Functional analysis indicated that DEGs were involved in plant hormones, glutathione and secondary metabolic pathways associated with tobacco resistance to bacterial wilt induced by R. solanacearum. Through subsequent Short Time-series Expression Miner (STEM) and weighted correlation network (WGCNA) analyses, the phenylpropanoid metabolic pathway was identifed as a key pathway for tobacco defense against R. solanacearum infestation. In summary, our results provide transcriptomic profles of tobacco response to R. solanacearum infestation

Background: Cervical cancer is the second most common cancer in women worldwide, with about 500,000 new cases and 270,000 deaths each year. Globally, it is estimated that over one million women currently have cervical cancer, most of whom have not been diagnosed, or have no access to treatment that could cure them or prolong their lives. In the United Arab Emirates (UAE) cervical cancer is the third most common cancer in women. Materials and Methods: A population-based cross-sectional retrospective survey of cervical smear abnormalities was conducted in the Emirate of Abu Dhabi, UAE, from January 2013 to December 2013 by collecting consecutive liquid-based cytology samples from the Department of Pathology at the SKMC Hospital in Abu Dhabi city. Results: The total number of women screened for cervical cancer for the year 2013 at SKMC was 4,593, with 225 (4.89%) abnormal smears. The majority of the abnormal smear results were atypical squamous cells of undetermined significance (ASCUS) 114 (2.48%). This study showed 60% increase in the rate of abnormal cervical smears in the UAE over the last 10 years. In this study the highest incidence of high grade abnormalities were seen in women above the age of 61years (1.73%), this might be due to the fact that this group of women missed the chance of screening of cervical cancer earlier in their lives or could be explained by the well-known second peak of HPV infection seen in many prevalence studies. Conclusions: We conclude that the rate of abnormal cervical smear in the screened Abu Dhabi women is not different from the rate in developed countries. A notable increase in both low and high grade abnormalities has occurred within the last decade.

기대일치이론에 기초한 기대일치모형은 정보시스템 연구 분야에서 정보시스템의 지속적인 사용 혹은 사용의도를 설명하는 핵심 이론으로 언급되어 왔다. 이러한 기대일치모형과 더불어 최근에 정보시스템 분야에서 주목을 받고 있는 또 다른 개념은 자동화된 행동 경향을 의미하는 ‘습관’이다. 본 연구에서는 이러한 두 가지 개념들을 기초로 모바일 인터넷 서비스에 대한 지속적인 이용 상황에서 습관과 기대일치모형을 통합하는 시도를 하였다. 이에 일치, 지각된 유용성, 지각된 사용 용이성, 습관 등의 수용후 신념, 이용자 만족, 지속적 이용의도로 구성된 연구모형을 구성하고 이를 검증하였다. J도내 250명의 대학생들을 대상으로 설문자료를 수집하여 분석한 결과, 기대일치와 지각된 유용성이 모바일 인터넷 서비스의 이용자 만족에 대한 주요 요인으로서 나타났다. 또한 지각된 유용성, 이용자 만족, 습관은 모바일 인터넷 서비스에 대한 지속적 이용의도를 결정하는 주요 요인으로 나타났다. 반면에 지각된 이용 용이성은 이용자 만족과 지속적 이용의도 모두에 대하여 아무런 관련성이 없는 것으로 나타났다.
Audit Fees and Hours after International Financial Reporting Standards Adoption

Nevertheless, methods of previous study conducted only with DART system’s existing corporate disclosure information have a limitation in study. Therefore, this study aims to identify change in audit fees and audit hours after the adoption of K-IFRS through questionnaire survey conducted on working-level auditors, and check whether or not such change properly reflects the changed environment of accounting audit market. In conclusion, audit fees resulting from open audit engagement system has changed to a structure in which appropriate time cannot be input due to low-priced competitive strategies. Improvement measures for this include assigned audit system expansion of regulatory authority, adoption of lower limit policy on audit fees, companies’ enhanced perception on audit, and auditors’ efforts to increase audit fees. This study possesses a high value in introducing immediate responses of auditors (i.e. C.P.A.), accounting specialists, for the reasons of why audit fees increases, why audit fees decreases, and why audit fees does not change, not identifying what percentage increases for a result of empirical study.
