Abstract

This research aims at describing the stage of the policy implementation of national standards for education, describing the determinant factors which support the policy implementation of national standard, and describing the forms of policy implementation of national standard for education in the implementation of the elementary school of national standard (SDSN) in Wajo regency. The research finding shows that: (1) the stage policy implementation of national standard for education in the implementation of SDSN has been implemented in accordance with the applicable legislation, but it has not been implemented optimally. Among 385 elementary schools, there are only 11 schools which have category SDSN category, (2) the determinant factors which support the policy implementation of national standard for education are content and context of the policy especially infrastructure, educator, content standard, and educational assessment standard, (3) the forms of national standard for education consist of Elementary School motivated to involve in the policy implementation of SD-SN. The policy of SD-SN becomes a supporter for the school to explore the potential of non-governmental. In addition the position of decision-making in the policy implementation of national standard for education in the elementary school is at level of headmaster and education department. Therefore, the motivation and monitoring as a continuous leading is conducted in integrated.

Correlation between glycosylated HbA1c level and severity of coronary atherosclerosis in non-diabetics
Abstract

Background: Glycosylated hemoglobin A1C (HbA1c) has been widely recognized as a marker for predicting the severity of diabetes mellitus (DM) and several cardiovascular diseases. However, whether HbA1c could predict presence and severity of coronary artery stenosis in non diabetic patients remains largely unknown. Aim of the work: To study glycosylated hemoglobin level (HbA1c) as an index of presence and severity of coronary artery disease in non-diabetic patients. Methods: We enrolled 100 non diabetic patients underwent coronary angiography for evaluation of chest pain. Patients were included if they had no history of prior revascularization or diabetes mellitus and had fasting blood glucose < 126 mg/dl (7.0 mmol/l) and HbA1c < 6.5% (47mmol/mol). The severity of the CAD was also evaluated using the Gensini score. Serum HbA1c, lipid profile, resting ECG, Echo Doppler and HOLTER monitoring were measured. The patients were classified into two groups by tertiles of baseline HbA1c level (low group (nondiabetics) <5.7%, n = 55; high group (prediabetics) between 5.7 and 6.3%, n = 45). The relationships between the plasma HbA1c and presence and severity of CAD and early clinical outcomes were evaluated. Results: There were a statistically significant correlation between the level of plasma HbA1C and angiographic characteristics (P <0.001), statistically significant correlation between the level of plasma HbA1C and total silent ischemic episodes detected by Holter monitoring (P =0.04) and statistically insignificant correlation between the level of plasma HbA1C and myocardial systolic function measured by EF % (P =0.5) Conclusion: High. HbA1C level was an independent predictor of the presence of CAD after adjusting for conventional risk factors of CAD (AUC = 0.8).

Toxic and essential metal concentrations in roasted Plantain and fish commonly consumed by Port Harcourt inhabitants, Rivers state, Nigeria
Abstract

Of recent, the consumption of roasted Plantain and fish popularly known as Bole during lunch hours in Port Harcourt has been on the increase. Considering the open nature by which this meal is prepared along roadside and the industrial concentrations of the Port Harcourt metropolis, most inhabitants of the city believed that these food items may have been polluted by metals. Hence, this study was necessitated to actually ascertain the levels of some toxic and essential metals in roasted plantain and fish in the city. Food samples were collected from eight locations based on high population of the area, high vehicular movements and presence of industries. The collected food samples were prepared, digested and subjected to heavy metals analyses using the atomic absorption spectroscopy. The results of the detectable concentrations (mg/kg) of the metals in the roasted plantain were: Cd (0.062±0.1289) mg/kg, Pb (0.135±0.1207) mg/kg, Zn (21.33±13.203) mg/kg, Fe (58.19±14.73) mg/kg, Cr (0.054±0.3002) mg/kg, Mn (0.026±0.0273) mg/kg, Ag (0.036±0.0197) mg/kg and As (0.038±0.0243) mg/kg. In the roasted fish the mean concentrations with standard deviation were: Cd (0.007±0327) mg/kg, Pb (0.07±0.066) mg/kg, Zn (29.6±27.34)mg/kg, Fe (44.103±19.838)mg/kg, Cr (0.64±0.289)mg/kg, Mn(0.03±0.0192) mg/kg, Ag(0.0215±0.0174) mg/kg and As(0.0145±0.0141)mg/kg. These results showed that the mean concentration of all the essential metals in roasted plantain and fish were within the recommended limit set by WHO/FAO. For the heavy metals, the mean concentrations were within the recommended limits in the plantain and fish except in few locations where the concentrations of Pb, Cd, Ag and As were slightly elevated. Based on the findings, roasted plantain and fish may be considered fit for consumption. The slight increase in concentration at some locations however calls for caution considering the non-biodegradable nature and accumulative properties of heavy metals.

Role of different CT techniques in grading of liver fibrosis in viral hepatitis patients
Abstract

This study aims to evaluate the role of perfusion CT in grading of liver fibrosis, seeking for a simple tool that may be helpful in evaluation of a very common problem. Fifty one hepatitis C patients applying for Egyptian ministry of health antiviral therapy (Peginterferon alfa-2b 1.5 mcg/kg weekly + Ribavirin 800 mg daily) were included in the study. All the group were subjected to the routine clinical assessment, lab and imaging protocol. Lab assessment included CBC, AL, AST, liver and kidney function tests, HBsAg, HCV Ab, HCV PCR, abdominal ultrasound, and true cut liver biopsy. Perfusional CT scan was added and perfusional parameters was calculated. These results show that each of portal perfusion, total hepatic perfusion and transit time can be used to differentiate mild from moderate liver fibrosis. The best single factor was portal hepatic perfusion. Using portal hepatic perfusion value of 102 ml /min/100ml showed a sensitivity of and specificity of 83%. At this value efficiency of the test is about 80%.

The policy of clean water supply by identifying critical areas in Banyuwangi, East Java
Abstract

This study aimed to determine the policy of clean water supply in area of clean water crisis in Banyuwangi. The study was conducted in 5 subdistricts, namely Wongsorejo subdistrict, Licin subdistrict, Songgon subdistrict, Kalibaru subdistrict and Pesanggaran subdistrict. Two analyses were conducted in this study, namely; the analysis of the clean water needs and the analysis of clean water availability. Four parameters were used in this study, namely: a) forest area; b) rainfall; c) total area; and d) population. The results showed that among those five subdistricts in Banyuwangi, only Kalibaru subdistrict was considered as area with clean water crisis due to its population of 61,820 inhabitants within an area of 18,741.80 km2. The result of clean water needs measurement (K) was 353,870.9 m3/year and groundwater recharges (RC) as 556,633 m3/year (the clean water needs has not been fulfilled). To this problem, the local governement of Banyuwangi should do reforestation of 0.78% denuded forest in order to cover 30% of forest area in Kalibaru subdistrict according to the Law of the Republic of Indonesia Number 26 Year 2007 about spacial planning. Therefore, the role of forests was extremely needed in order to serve the environment both socially and economically and give advantages to the local community.
