The question of compensation in addition to sensitive to be driving someone to worl due to an effect on morale and discipline employees. Therefore , any  agency or any organization should be able to provide compensation equal to the workload  to create a workforce that efficient and effective manner can be realized. Amaore than that, the company’s goal to improve performance. Performance assessment is a subjective process that involves human judgments. Thus, performance assessment is very likely wrong and very easily influonced by sources that are not actual, so it must be taken into account and considered reasinable. Frformance appraisals are considered  to meet the target if it has a good impact on new employees who rated their performance. Simple linear regression analysis using SPSS version 12:00 data processing obtained tegression equation Y = 0,487 X 74 + with an explanation of X = award, 74 = constant, 0.487 = coefficient awards, and Y = performance based on simple linear regression equation in case of increase of one unit of the  performance award will be increased 0.487 units.

Linear and quadratic trend surfaces were computed for textural, carbonate, clast, and heavy mineral properties of the Catfish Creek (Nissouri Stadial), Port Stanley (Port Bruce Stadial), Tavistock (Port Bruce Stadial), and Wentworth (Port Huron Stadial) tills.Catfish Creek Till pebble grade material provided trend surfaces reflecting the underlying bedrock. However, an overall lack of regional trends in Catfish Creek Till is consistent with field observations that indicate remarkable uniformity for this till over several hundred square kilometres, a phenomenon that is believed to reflect the high energy of this ice sheet. Carbonates in Port Stanley Till were found to increase from east to west as the Silurian–Devonian contact was crossed. Tavistock Till was found to have increasing sand content and decreasing silt content from northwest to southeast owing to incorporation of underlying glaciofluvial sediments; pebble trends reflect the underlying bedrock for the most part. Wentworth Till trend surfaces for carbonates and pebbles show high dolomite near the Niagara Escarpment to the east and northeast with a dilution of dolomite and influx of limestone to the southwest.The strong relationship of the trend surfaces to substrate materials indicates the basal nature of the tills and the local origin of most glacial deposits. Pebble lithologies provide much information about local bedrock and drift prospectors should give close consideration to coarse fragments.

Abstract Background In recent years new forms of syndromic surveillance that use data from the Internet have been proposed. These have been developed to assist the early prediction of epidemics in various cases and diseases. It has been found that these systems are accurate in monitoring and predicting outbreaks before these are observed in population and, therefore, they can be used as a complement to other methods. In this research, our aim is to examine a highly infectious disease, measles, as there is no extensive literature on forecasting measles using Internet data, Methods This research has been conducted with official data on measles for 5 years (2013–2018) from the competent authority of the European Union (European Center of Disease and Prevention - ECDC) and data obtained from Google Trends by using scripts coded in Python. We compared regression models forecasting the development of measles in the five countries. Results Results show that measles can be estimated and predicted through Google Trends in terms of time, volume and the overall spread. The combined results reveal a strong relationship of measles cases with the predicted cases (correlation coefficient R= 0.779 in two-tailed significance p< 0.01). The mean standard error was relatively low 45.2 (12.19%) for the combined results. However, major differences and deviations were observed for countries with a relatively low impact of measles, such as the United Kingdom and Spain. For these countries, alternative models were tested in an attempt to improve the results. Conclusions The estimation of measles cases from Google Trends produces acceptable results and can help predict outbreaks in a robust and sound manner, at least 2 months in advance. Python scripts can be used individually or within the framework of an integrated Internet surveillance system for tracking epidemics as the one addressed here.

Seagrass beds in Ujung Genteng waters are one of the shallow marine ecosystems that have relatively high biodiversity. Seagrass ecosystem as one of the coastal ecosystems in these waters has a diversity of marine life that is associated with it. The purpose of this study was to establish the association pattern and the correlation of mega zoobenthos to seagrass ecosystem conditions. The method used was a survey method by conducting a survey direct observation of the stations that have been determined.  Three seagrass species were identified, namely: Thallasia hemprichii, Cymodoceae rotundata and Enhalus acoroides. The highest density of seagrass was found in station 2 with the type of seagrass Thallasia hemprichii as much as 207 ind/m2. Fifteen mega zoobenthos species were identified representing 3 phyla. Species Mega zoobenthos which is most commonly found in Ujung Genteng waters is Ophiothrix fragilis, Ophiocoma erinaceus, and Diadema setosum. The mega zoobenthos Diversity Index at the observation station is included in the medium category that is 2.33-2.66 and the evenness index is 0.63-0.84. Correlation of seagrass density with mega zoobenthos obtained by 0.92 shows that there is a very strong relationship between seagrass density with mega zoobenthos. The result shows that there are 4 patterns of close association and 2 patterns of very close association. Ophiocoma erinaceus of the ophiuroidea class has a pattern of very close positive associations with seagrass Cymodoceae rotundata and Dendrodoris sp of the order nudibranchia has a pattern of very close negative associations with seagrass Cymodoceae rotundata.

Based on data from the Tikep Health Center, for the last three years Waturempe Village has become the village with the highest incidence of skin diseases and accounts for almost 50% of skin diseases. The aim of this study was to determine the relationship between personal hygiene and environmental conditions in Waturempe Village. The population in this study were all heads who live in Waturempe Village as many as 120 heads of families (KK). The sample size was 92 respondents, taken by simple random sampling. The data were obtained using a questionnaire then analyzed descriptively and inferentially using the chi square test. The results showed that there was a strong relationship between personal hygiene (X²hit=39,21 2> X²tab = 3,841), moisture (X²hit=36,655 > X²tab=3,841), temperature (X²hit=45,126 > X²tab=3,841), natural lighting (X²hit=29,362> X²tab=3,841), and occupancy density (X²hit=27,273 > X²tab=3,841) with complaints of skin diseases. There was a moderate relationship between water quality and complaints of skin diseases (X²hit=19,354 > X²tab=3,841). It is expected that the community always maintains personal hygiene and improves condition of the home environment and is always aware of the transmission of skin diseases.

AbstractThe fatigue behavior of cotton warps was studied by a newly weaving load simulator (WLS) developed in our laboratory. Reborn hairiness, strength retention, and elongation retention of sized warps were adopted to evaluate the physical and mechanical properties of sized warps under stretch-abrasion cyclic loading. The influences of different fatigue cycles on the above three indicators were also discussed. The results indicated that the fatigue behavior of the cotton warps accompanied by abrasion yields a three-parameter Weibull distribution. All the fitting plots show acceptable linearity. Moreover, there is a strong relationship of quadratic polynomial between the tensile properties and the fatigue cycle of the sized warps according to the scatter fitting (R2 > 91.08%). Similarly, there is also a good relationship of quadratic polynomial between the reborn hairiness index and the fatigue cycle of the sized warps (R2 > 94.51%). Finally, regardless of the strength retention, elongation retention, and reborn hairiness, the physical and mechanical properties of the cotton warps still change with the continuous increase of the fatigue cycle after 40% of the fatigue cycle, but it is not significant. The research was helpful to estimate the capacity of the warps to sustain failure.
