    Sea surface temperature (SST) and chlorophyll-a are important water qualityparameter in the sea, especially the coastal areas. The research was conducted inJanuary - March 2017 in the waters of Belawan, North Sumatera Province with theaim to determine the relationship of sea surface temperature and chlorophyllconcentrations-a.The method used is survey with direct measurements in the watersof Belawan, North Sumatera and using MODIS Aqua satellite image data in March2016 - February 2017. Sea surface temperature MODIS Aqua satellite image datain March 2016 - February 2017 ranged from 29.45 to 31.7oC and chlorophyll-arange of 0.48 to 2.62 mg / l. Field data sea surface temperature ranges from 26-30°Cand chlorophyll-a range of 2.08 to 17.62 mg / l. Interpretation of the data from theMODIS Aqua satellite imagery and field data to explain that the sea surfacetemperature and chlorophyll concentrations-a very weak, r = 0.1791. Data weremapped to show the variability of sea surface temperature and chlorophyll-aconcentrations March 2016 until February 2017

    Helicobacter pylori interstrain restriction-modification diversity prevents genome subversion by chromosomal DNA from competing strains

    Helicobacter pylori, bacteria that colonize the human gastric mucosa, possess a large number of genes for restriction‐modification (R‐M) systems, and essentially, every strain possesses a unique complement of functional and partial R‐M systems. Nearly half of the H.pylori strains studied possess an active type IIs R‐M system, HpyII, with the recognition sequence GAAGA. Recombination between direct repeats that flank the R‐M cassette allows for its deletion whereas strains lacking hpyIIRM can acquire this cassette through natural transformation. We asked whether strains lacking HpyII R‐M activity can acquire an active hpyIIRM cassette [containing a 1.4 kb kanamycin resistance (aphA) marker], whether such acquisition is DNase sensitive or resistant and whether restriction barriers limit acquisition of chromosomal DNA. Our results indicate that natural transformation and conjugation‐like mechanisms may contribute to the transfer of large (4.8 kb) insertions of chromosomal DNA between H.pylori strains, that inactive or partial R‐M systems can be reactivated upon recombination with a functional allele, consistent with their being contingency genes, and that H.pylori R‐M diversity limits acquisition of chromosomal DNA fragments of ≥1 kb

    Background: The quality of life of elderly people has become increasingly important with the demographic shift to greying population. Quality of life is defined by personal feelings, details, outlook, and day to day experiences, which include how happy and positive one feels, how comfortable and secure, how productive and desired, how healthy and free an individual considers themselves, etc. This study aimed to determine health behavior associated with quality of life among elderly with hypertension. Subjects and Method: This was a cross sectional study conducted at Puskesmas (community health center) Rowosari, Semarang, Central Java. A sample of 62 elderly with hypertension was selected for this study by simple random sampling. The dependent variable was quality of life. The independent variables were adherence to treatment, physical exercise, diet, and smoking. Quality of life was measured by Short Form-36. Dietary pattern was measured by food recall. The other data were collected by questionnaire. The data were analyzed by chi square with prevalence ratio (PR) as the measure of association. Results: Adherence to treatment (PR= 10.27; CI 95%= 2.85 to 36.94; p<0.001), physical exercise (PR= 12.00; CI 95%= 2.26 to 63.86; p= 0.001), good diet (PR= 1.80; CI 95%= 1.40 to 2.34; p= 0.001), and smoking abstinence (PR= 3.36; CI 95%= 1.04 to 10.90; p= 0.038) were associated with better quality of life in elderly with hypertension. Conclusion: Adherence to treatment, physical exercise, good diet, and smoking abstinence are associated with good quality of life in elderly with hypertension

    Abstract: The economy in Indonesia is affected by pandemic COVID-19, resulting in a 5.32% decline in the 2nd quartal of 2020. The government issued tax incentive during this pandemic. This study aims to understand motivation postures (commitment, capitulation, resistance, game playing dan disengagement) towards tax compliance in 2019 and perception of tax compliance in 2020. Respondent in this research are SME tax payers in Surabaya. The results show that resistance and game-playing affect tax compliance in 2019, commitment affect perception of tax compliance in 2020 and tax incentive moderating commitment towards perception of tax compliance in 2020
