Abstract

A research about reservoir characterization with analysis of AVO (Amplitude Variation with Offset) and seismic inversion, to extract the petrophysics properties on the EP field South Sumatra Basin. This research was conducted to identify rock lithology and its spread, to see the sensitive parameters of physical properties of rocks. This research uses the 3D seismic data PSTM (Pre Stack Time Migration) as input control with data from the EP-036 well containing sonic log, density, gamma rays, neutron and resistivity log. From the results of data analysis on the well log chart EP-036, reservoir target zones are at a depth of 714 to 722 m (TVD) or time domain 768 to 780 ms. The results of the analysis AVO is able to detect the presence of reservoir gas sand, based on the classification of Rutherford and Williams (1989) the gas sand layer into AVO class III that indicates low impedance contrast sands. To analyze the results of well log data in the cross plot EP-036 indicates lithology is a hydrocarbon. It is also reinforced with cross plot analysis and seismic inversion results in the form of the parameter value ??, Vp/Vs and Acoustic impedance with low porosity averaging 22 to 35%, indicating that the zone is a zone reservoir potential gas sand.

Evaluative connotation of the component “right” in phraseological units of english and russian
Authors: Gaibova Leysan Saifidinovna , Safina Rimma Abelkhaerovna , Knachukova Alina Faritovna 
Published: December 2020

The article describes the results of research work on the evaluative properties of the component “right / правый” in the phraseological units of English and Russian. The lexico-semantic analysis has shown that in the composition of phraseological phrases, when interacting with other linguistic units, an intensification of the evaluativity of the component “right / правый” can occur, as a result of which the expressive-evaluative properties of the whole utterance are intensified. The intensification of evaluative connotation of the component can be actualized by using the stylistic devices and lexical repetition. The somatism components are used most frequently as the linguistic units that are part of the lexical environment of the component “right / правый”. The combination of the component “right / правый” with somatisms is of concern from the point of view of the formation of holistic concepts, collective visions that accumulate positive or negative evaluativity. The significance of the evaluative semantics of the component “right / правый” lies in the fact that when interacting with other components of a phraseological unit, it is filled with ideological content.

Professional Quality of Life (ProQOL) is a topic that has been growing for the last 20 years. Stamm is an expert who is developing theoretical concepts and its instrument in 2010. ProQOL explains individual’s perceptions professional quality of life, which consists of two aspects. Compassion Satisfaction (CS) is the positive aspect where someone is able to feel positive feelings such as altruism while working and Compassion Fatigue (CF) is the negative ones, where someone feels uncomfortable which can leads to Burnout and Secondary Traumatic Stress (STS) symptoms. Most of study has investigated ProQOL among health caring professional, therefore this study aims to overview ProQOL among special education teachers. Uses quantitative-non experimental design, this study involves 171 special education teachers as participants. Based on the collected data, it shows that individual’s perceptions about the quality of life as a special education teacher tends to be positive. However, this is not necessarily followed by low STS and burnout rates. This study found that around 77% teachers were at moderate to high burnout levels, while 72% also had moderate to high STS levels. Professional Quality of Life (ProQOL) merupakan sebuah topik yang sudah berkembang sejak 20 tahun terakhir. Seorang ahli bernama Stamm telah berjasa dalam mengembangkan konsep teoretis ProQOL beserta alat ukurnya pada tahun 2010. ProQOL menjelaskan persepsi individu mengenai kualitas hidup profesionalnya, yang terdiri dari dua aspek. Compassion Satisfaction (CS) merupakan aspek positif dimana individu mampu merasakan perasaan positif, altruisme terkait perkerjaannya dan Compassion Fatigue (CF) yang merupakan aspek negatif, dimana individu merasa tidak nyaman dalam menjalankan pekerjaannya yang berujung pada gejala Burnout dan Secondary Traumatic Stress (STS). Oleh karena sebagian besar penelitian mengenai ProQOL telah diteliti pada tenaga profesional kesehatan, penelitian ini bertujuan untuk memperoleh gambaran ProQOL pada profesi guru ABK. Penelitian ini merupakan penelitian kuantitatif non-eksperimental yang melibatkan 171 guru ABK sebagai partisipan. Berdasarkan data yang terkumpul diperoleh bahwa persepsi individu terhadap kualitas hidup profesional sebagai guru ABK cenderung positif. Akan tetapi, hal tersebut tidak serta merta diikuti dengan tingkat burnout dan STS yang rendah. Berdasarkan hasil penelitian, sekitar 77% guru ABK berada pada tingkat burnout Sedang-Tinggi dan 72% diantaranya juga memiliki tingkat STS Sedang-Tinggi.
