World Journal of Emergency Medicine 2018年第3期9卷 178-186页

BACKGROUND： Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian ***： A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS： The highest prevalence was anxiety （28.6%） followed by depression （10.7%） and stress （7.9%）. Depression, anxiety and stress between seven hospitals were not significantly different （P〉0.05）. Male medical officers significantly experienced more anxiety symptoms than female medical officers （P=0.0022）, however depression and stress symptoms between male and female medical officers were not signi？ cantly different （P〉0.05）. Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals （P〉0.05）. CONCLUSION： The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers’ anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

A rare cause of acute abdomen–Spontaneous rectus sheath hematoma

Asian Pacific Journal of Tropical Biomedicine 2016年第10期6卷 892-895页

作者： Hock Chin Chong Feng Yih Chai Yew Eng Tan Sophia Si Ling Heng siti Asilah Mohd Desa Department of Surgery Hospital Queen Elizabeth Department of Surgery Hospital Keningau

Spontaneous rectus sheath hematoma(SRSH) is a rare entity that mimics acute *** sheath hematoma is the accumulation of blood in rectus sheath due to muscle or epigastric vessel injury. However, SRSH without a trauma or anticoagulation is rare. It frequently mimics acute abdomen and it may lead to misdiagnosis and unnecessary laparotomy. In this article, we described two cases of SRSH with their diagnostic and therapeutic strategy. Both of our patients in report were neither consumed antiplatelet nor coagulopathy. They both had abdominal muscle straining before their symptoms presentation. We hypothesized that the SRSH may be induced by rectus muscle injury secondary to inappropriate straining or posture. To diagnose SRSH, clinical findings are important but radiologic imaging such as computed tomography, can be diagnostic. In expanding SRSH, percutaneous arterial embolization of epigastric artery is useful to secure the bleeding. If embolization is not feasible, surgical exploration hemostasis is curative. In non-expanding SRSH, it can be managed nonoperatively. SRSH is an important initial differential for acute abdomen. Radiologic imaging helps in *** SRSH can be managed conservatively with good outcome.

Intelligent Dynamic Aging Approaches in Web Proxy Cache Replacement

引用

Journal of Intelligent Learning Systems and Applications 2015年第4期7卷 117-127页

作者： Waleed Ali siti Mariyam Shamsuddin Department of Information Technology Faculty of Computing and Information Technology King Abdulaziz University Rabigh Kingdom of Saudi Arabia Faculty of Computing Universiti Teknologi Malaysia Johor Malaysia

One of commonly used approach to enhance the Web performance is Web proxy caching technique. In Web proxy caching, Least-Frequently-Used-Dynamic-Aging (LFU-DA) is one of the common proxy cache replacement methods, which is widely used in Web proxy cache management. LFU-DA accomplishes a superior byte hit ratio compared to other Web proxy cache replacement algorithms. However, LFU-DA may suffer in hit ratio measure. Therefore, in this paper, LFU-DA is enhanced using popular supervised machine learning techniques such as a support vector machine (SVM), a naive Bayes classifier (NB) and a decision tree (C4.5). SVM, NB and C4.5 are trained from Web proxy logs files and then intelligently incorporated with LFU-DA to form Intelligent Dynamic- Aging (DA) approaches. The simulation results revealed that the proposed intelligent Dynamic- Aging approaches considerably improved the performances in terms of hit and byte hit ratio of the conventional LFU-DA on a range of real datasets.

Production and Nutritive Value of Shrub Legumes in West Timor, East Nusa Tenggara Province Indonesia

引用

Journal of Agricultural Science and Technology(A) 2013年第5期3卷 349-355页

作者： Sophia Ratnawaty Hartutik Soebarinoto siti Chuzaemi Postgraduate Program Faculty of Animal Husbandry University of Brawijaya Malang East Java 65145 Indonesia Assesment Institute of Agriculture Technology East Nusa Tenggara Kupang East Nusa Tenggara Province 85362 Indonesia Department of Animal Nutrition Faculty of Animal Husbandry University of Brawo'aya Malang East Java 65145 Indonesia

This study aimed to identify the potential of shrub legumes as protein feed in West Timor. Eight shrub legumes, i.e., Clitoria ternatea Q5455 （CT Q5455）, Clitoria ternatea millgara （CT millgara）, Centrosema pascuorum bundey （CP bundey）, Centrosema pascuorum molle （CP molle）, Macroptilium bracteatum juanita （MB Juanita）, Macroptilium bracteatum cadaarga （MB cadaarga）, Dolichos lablab （DL） and Stylossanthes seabrana （SS） were evaluated for their yield and nutritive value in Randomized Block Design. Each legume was cultivated in four plots of different soil fertility as block （5 ~ 5 m2 per plot）. Phosphorus （P） fertilizer was applied once just before planting at level of 50 kg ha~. Watering was done three times per week using sprinkler. The legumes were harvested at 120 days after planting （dap） in three sub-plots of 1 x 1 m2 size for their yield measurement. Samples of each legume was taken for Dry Matter （DM）, Organic Matter （OM）, Crude Protein （CP）, cellulose, hemi-cellulose and lignin content and in vitro DM, OM and CP digestibility test. Data were statistically analyzed using Genstat release 12.2. The results showed that the legumes showed significantly different （P 〈 0.01） in biomass yield. The highest biomass yield was shown by SS （6,739 kg DM ha-l; 6,120 kg OM ha1 and 1,224 kg CP hal） and the lowest was by DL （1,294 kg DM ha^-1; 1,157 kg OM ha^-1 and 242 kg CP ha^-1）. In general, there was no significant difference （P 〉 0.05） of DM digestibility of the eight legumes, except for DL which showed significantly highest （P 〈 0.01） DM and OM digestibility compared to the other.
