Optimal remote access trojans detection based on network behavior

RAT is one of the most infected malware in the hyper-connected world. Data is being leaked or disclosed every day because new remote access Trojans are emerging and they are used to steal confidential data from target hosts. Network behavior-based detection has been used to provide an effective detection model for Remote Access Trojans. However, there is still short comings: to detect as early as possible, some False Negative Rate and accuracy that may vary depending on ratio of normal and malicious RAT sessions. As typical network contains large amount of normal traffic and small amount of malicious traffic, the detection model was built based on the different ratio of normal and malicious sessions in previous works. At that time false negative rate is less than 2%, and it varies depending on different ratio of normal and malicious instances. An unbalanced dataset will bias the prediction model towards the more common class. In this paper, each RAT is run many times in order to capture variant behavior of a Remote Access Trojan in the early stage, and balanced instances of normal applications and Remote Access Trojans are used for detection model. Our approach achieves 99 % accuracy and 0.3% False Negative Rate by Random Forest Algorithm

In vitro study of Coronal Leakage of Four Temporary Filling Materials Immersed in Alcoholic Methylene Blue Dye

Abstract Introduction: Temporary restorative materials are placed in access cavity to provide the coronal seal of the root canal during multi-visits RCT. This in vitro study was designed to evaluate the coronal microleakage of four different temporary restorative materials commonly used in endodontics in Myanmar, viz., MD.Temp, Orafil, Caviton, Zinc oxide eugenol. Materials and Methods : Forty-four extracted human premolars were selected, and access cavity was prepared. Pulp chambers were filled with wet cotton pellets leaving approximately 4 mm coronally. Forty teeth were randomly divided into four experimental groups equally. The remaining four teeth were equally divided into two control groups. Access cavities in each group were filled with one of the above tested materials, and immediately put into the water. Tooth surfaces except occlusal surface were then coated with nail varnish. Equal parts of 2% methylene blue and methylated alcohol were mixed to prepare a dye solution. Samples were immersed in dye for 10 days at 32 ± 2°C. Teeth were rinsed, dried, and sectioned mesiodistally and evaluated under a stereomicroscope at a magnification of 15X for linear dye penetration along cavity walls. Data were analyzed using KruskalWallis and Tukey HSD tests. Results : The lowest microleakage value was observed in MD.Temp and Orafil, and the highest in Zinc oxide eugenol (ZOE). Caviton was not statistically different from Orafil and ZOE, but significantly higher in microleakage than MD.Temp. Clinical Significance : ZOE which is dissolvable in alcohol was the least effective material for preventing microleakage, while MD.Temp and Orafil provided the best sealing in content of alcohol in this study

Evaluation of optimal lysine level in Myanmar local breed and DYL crossed breed pig

 A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 12 weeks old, nine castrated DYL and nine castrated local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 1.15% total lysine for grower and L3- basal diet with 1.65% total lysine for grower. The growth performance and feed intake were determined for growing pigs. In this study, no significant difference (p>0.05) was found in feed intake among the three different treatments. However, significantly better body weight, weight gain and feed conversion ratio (FCR) were observed in pigs fed L2 and L3 but were not significantly (p>0.05) differ from each other. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and farm efficiency. Between the two breeds, body weight of DYL was superior over that of local breed. The interactions were observed between lysine levels and different breeds regard for body weight and cumulative weight gain. To wrap up, it was noticeable that crystalline lysine supplementation helped to improve growth performance in both breeds

Effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population of broiler chickens

A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each in order to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield was not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, Lactobacilli count in the gut of broilers significantly (p<0.05) increased in T2 compared to that of T1. Lactobacilli count in the gut of broilers received T1, T3 and T4 did not differ significantly (p>0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of Lactobacilli

The effect of lysine supplementation on the performance of Myanmar local breed and DYL crossed breed pig

A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 18 weeks old, nine castrated DYL and nine local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 0.95% total lysine for finisher and L3- basal diet with 1.45% total lysine for finisher. The growth performance and back fat thickness were determined for finishing pigs. Significantly better body weight, weight gain, feed conversion ratio (FCR) and lower back fat were observed in pigs fed L2 but did not significantly differ from those fed L3. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and feed efficiency. Between the two breeds, growth performances of DYL were superior over that of local breed. Back fat thicknesses of DYL were also thinner than that of local breed. The interactions were observed between lysine levels and different breeds regard for final body weight, cumulative gain and feed conversion ratio. It was noticeable that lysine supplementation helped to improve growth performance and reduce back fat thickness of both local breed and DYL crossed breed. The result also showed that a comparison of the two different breed revealed the improved performances in DYL crossed breed rather than that of local breed. &nbsp

Application of IgM-capture ELISA on Myanmar Dengue Patients\u27 Serum Samples Collected in 1994

Seventy serum samples from clinically diagnosed dengue patients admitted to the North Okkalapa General Hospital, Yangon, Union of Myanmar, in 1994, were used to obtain the confirmed virological diagnosis by IgM-capture ELISA using all four types of dengue antigens raised by cell culture method. Sixty-two out of 70 specimens (88.6%) showed positive IgM ELISA titer against one or more assay antigen. Single application of dengue 2 antigen could detect 59 out of 62 positive sera (95.1% of total positives), whereas three more samples could be detected by using other serotypic antigens (either single antigen or double antigens in combination). Ten samples showing positive by single dengue antigen but negative results by the rest could possibly be due to the primary infection which showed serotype specific immune response

Optimization of the Dengue-2 Antigen ELISA Titer for the Positive Case Detection of Dengue Virus Infection by IgM ELISA

We have determined the dengue-2 antigen ELISA titer for the positive case detection of dengue virus infection by IgM ELISA using 33 paired serum samples of dengue patients admitted to the North Okkalapa General Hospital, Yangon, Union of Myanmar, in June and July, 1994. The antigen ELISA titer was found to be over 32 units in order to find out sufficient number of positive cases. This finding can be used as a reference for further experiments and the development of tetravalent dengue antigen for routine serodiagnosis of dengue virus infection

Role of inclusive self-help groups in prevention and management of diabetes and hypertension in Myanmar:a qualitative study

Background: Noncommunicable diseases (NCDs) are a growing public health concern in Myanmar. Community-based self-help groups are essential for participating in health-related activities. However, little is known about the role of inclusive self-help groups (ISHG) in hypertension and diabetes management. This study aimed to assess knowledge and perception of health-related activities of ISHG and explore challenges ISHG group members encountered in performing hypertension and diabetes prevention and management activities.Methods: The study included six townships from three different regions of Myanmar, where ISHG existed. Two focus group discussions (FGDs) were held in each township. A total of twelve FGDs were conducted. All discussions were conducted, audio-recorded and transcribed verbatim in Myanmar language. A thematic analysis was performed using inductive and deductive approaches.Results: The findings revealed that ISHG members provided advice and counselling on behavioural risk factors for hypertension and diabetes prevention and screenings for those diseases. They also offered home care for the elderly and stroke patients who required their assistance. Community members regarded ISHG as a valuable community structure. Members of the ISHG identified a number of challenges, including lack of resources (funding, manpower, and time), lack of confidence, and lack of recognition and acceptance. Support and strengthening activities by local authorities and the government were critical to sustain ISHG's activities and efforts.Conclusions: Hypertension and diabetes management activities of ISHG are appreciative. The public and government should recognize and support ISHG to strengthen their community activities
