The Relationship Between Anxiety Levels and Blood Pressures of Laboratory Practicum Participants Among Medical Students in University of Tadulako

2019-09-16T08:32:10+00:00

University students are potentially to suffer academic related stress or other psychological problems. Anxiety is a term used for some disorders which cause nervousness, worry, fear, and apprehension. Student may suffer different levels of anxiety in different period including exam period or test period. this condition can lead to overload and certain health problems. This is a cross sectional study involving 128 medical students attending biochemistry laboratory practicum in Faculty of Medicine Tadulako University. Automatically tensimeter was applied to measure the blood pressure and HARS was used to measure anxiety levels. There is a correlation between anxiety and blood pressure with p=0.005 and coefficient correlation 0.247.

New Discriminant Functions and Geochemistry of the Mamfe Cretaceous Formations (South West Cameroon)

2019-09-16T07:54:39+00:00

Major and trace element geochemistry have been used to unravel the tectonic setting, source rock composition, and depositional environment of sedimentary rocks in the Mamfe formation. Field studies reveal both sub tabular and tabular outcrops indicating a post tectonic sedimentary activity for the subtabualar outcrops. Major element geochemistry reveals a moderate to high proportion (50-75wt %) of silica for the analyzed samples. New discriminant diagrams constructed for usage of adjusted major elements shows samples plotting on collision, arc and rift. Another discriminant plot for adjusted major element combined with trace elements shows samples plotting on active and passive tectonic setting. Ratios of highly immobile trace elements such as Cr/Th, Th/Sc, Th/Co, and La/Sc conclude a felsic source rock for the studied rocks of the Mamfe formation. Trace elements ratios for redox conditions and marine-continental discrimination such as Ni/Co, U/Th, V/Cr, Th/U, and Y/Ho show that the sedimentary rocks of the formation were deposited in a shallow oxygenated continental fluvio-lacustrine environment.

Robust Geographically and Temporally Weighted Regression Using S-estimator in Criminal Case in East Java Province

2019-09-16T06:30:51+00:00

Geographically weighted regression (GWR) is a model that can be used for data with spatial varying. Geographically and Temporally Weighted Regression (GTWR) is a development of the GWR model for data spatial and temporal varying. Parameter estimation in GTWR model uses weighted least square method which is very sensitive to outliers data. The outlier caused bias in parameter estimation, so it must be handled by robust GTWR (RGTWR). In this research, S-estimator was used to handle outliers and estimate an RGTWR. Both GTWR and RGTWR is used to build model crime rate in East Java 2011-2015. The Crime rate is used as a response variable and the percentage of poor people, population density, and human development index are used as explanatory variables. The best model in this research is RGTWR using S-estimator. RGTWR using S-estimator has a coefficient of determination equal to 98,2 meanwhile RMSE equal to 33.941 and MAD equal to 4.994.

Effects of Water Depth on Growth Performance of Indian Major Carps at a Poly Culture System in Bangladesh

2019-09-16T17:19:38+00:00

The main aim of this study was to assess the effects of water depth on the growth performance (length and weight) of table size Indian major carp (Gibelion catla, Labeo rohita, and Cirrhinus mrigala) fishes. Fishes were recorded under different depth (1.20 m, 1.80 m and 2.80 m) for about eight months from February 2016 to September 2016. Water depth was considered as treatment 1 (T₁) for 1.20 m, treatment 2 (T₂) for 1.80 m and treatment 3 (T₃) for 2.80 m, respectively. Randomized Complete Block Design (RCBD) with two replications of each treatment was differentiated at significant level 5%. Various water quality parameters such as water temperature, dissolve oxygen, transparency, and pH were also recorded. The survival rate was found maximum (99.23±0.4%) for Labeo rohita fish at 2.80 m water depth and lowest (95±2.1%) survival rate was observed for Gibelion catla fish at 1.20 m water depth. Results of this study showed that Gibelion catla, Labeo rohita and Cirrhinus mrigala fish cultivated at four feet depth of water produces lowest average weight of 1398 g, 1048 g and 1050 g, respectively with an average length of 47 cm, 49.2 cm and 46.4 cm, respectively.

The maximum average weight of fish 3667 g, 2700 g and 2800 g were obtained at 2.80 m depth of water with the maximum average length of 63.2 cm, 60.0 cm and 58.6 cm for Gibelion catla, Labeo rohita and Cirrhinus mrigala fish, respectively. From this study, it can be observed that the fishes cultivated at low depth of water yielded lowest, and shorter in length in contrast to the carps cultivated at higher depth of pond water. However, the growth of Gibelion catla was notably high among other carps.

The Impact of Videos in Efl Classroom

2019-09-10T20:29:31+00:00

The aim of the paper is to investigate the impact that videos played during EFL classes as well as the learners’ improvement of the language. It is known that learning another language means learning another culture, traditions and gestures. Therefore, another approach is being used in different teaching and learning contexts. Most importantly, teachers involved in teaching languages should find different ways to offer students variety and increase their motivation in the EFL classroom. In the last century, in particular the last three decades, teaching methods have changed constantly in order to help learners acquire the desired knowledge, by having fun, too. The main emphasis was put in developing student communication skills. Nowadays, there are many different ways of teaching EFL and in particular, technology, which has enabled us to use numerous ways of teaching and learning a foreign language. Textbooks that are used to teach another language are full of pictures and animations which help learners to have an image while being taught. Besides, pictures and conversations, the textbooks used in EFL classes are equipped with recorded tapes of conversations and songs recorded by native speakers in order to help learners’ with their pronunciation. The participants of the study are students from a private Language School ‘’Oxford Studio’’ in Gjilan. Their answers show that they seem to enjoy watching videos in the classroom, and are motivated to discuss them afterwards with their teacher.
