An experimental investigation was carried out to determine the corrosive impact of oxidizing and non-oxidizing environments on sensitized welded and unwelded samples of AISI 304. The selected samples were cut into several sizes. To induce sensitization, the samples were heated and soaked at 750oC at different soaking time intervals such as 30 minutes, 60 minutes, 180minutes, 300 minutes and 600 minutes followed by water quenching [1]. The resultant sensitized weldment and unwelded samples were subjected to immersion duration test each in oxidizing (H2SO4) and non-oxidizing (HCL) media for 5, 10, 15, 20, 25, 30, 35, 40, 45, & 50 minutes respectively. From the results obtained, it was concluded that corrosion rate decreases as soaking time/immersion duration increases, at constant soaking temperature in non-oxidizing medium of hydrochloric acid (HCL). However, the corrosion rate decrease of the unwelded samples of AISI 304 in non-oxidizing medium is greater than that of their welded counterpart as immersion duration/soaking time increases. Similarly, the unwelded and welded samples of AISI 304, in oxidizing medium of H2SO4 have one common characteristic with their corrosion rate decreasing as soaking time/immersion duration increases; but, surprisingly, the welded samples are having lower corrosion rate than that of the unwelded counterpart as the immersion duration/soaking time increases between 5-15minutes; but reverses to a higher corrosion rate than their unwelded counterpart as immersion duration increases between 15-50 minutes. The results showed that each sample reacted differently in oxidizing and non-oxidizing media; hence oxidizing and non-oxidizing media impacted the materials’ properties differently. The sensitization differences of the welded and the unwelded counterpart obtained during soaking time, significantly affected their reactions in oxidizing and non-oxidizing media which led to differences in the corrosive impacts, under the same environment.

Vancomycin Resistant Staphylococcus aureus (VRSA) refers to bacteria that have complete resistance to Vancomycin. The increasing prevalence of VRSA can be a significant clinical problem with the limited therapeutic options. Therefore, the identification of VRSA is necessary to improve the management of antibiotic therapy, infection control and to prevent the occurrence of wider resistance. This retrospective descriptive study used secondary data of antibiotic susceptibility test on Staphylococcus aureus identified using VITEK 2 and patient medical records from January 2015 to December 2016. The data is processed using SPSS. Of 387 Staphylococcus aureus isolates obtained, 45 (11%) were VRSA. The most common VRSA isolates were male patients (57.8%) with the mean age being 41-60 years old (35.6%). The treatment ward with the most VRSA isolates were from surgical ward (20%), and internal medicine ward (15.6%) whereas the VRSA isolates from outpatient record were from surgical department (8.9%), dermatology department and ENT department (2.2%). The most common specimens were blood (28.9%), pus (26.7%), and sputum (20.0%). The highest prevalence of VRSA was found in the use of â‰¥ 3 invasive medical devices and from clinical outcome was found 11 (24.4%) of the patients died. Linezolid, Quinupristin / Dalfopristin, Tigecycline, and Nitrofurantoin as a therapeutic option have > 90% sensitivity. Identification of VRSA in Dr. Wahidin Sudirohusodo Hospital Makassar emphasized the need for immediate action by infection control division, especially in related units to prevent the transmission.

Background : End stage renal disease patients who undergo hemodialysis therapy are the high-risk populations who are infected by hepatitis C virus. Some studies have been reported that hepcidin levels decreased in patients with chronic hepatitis C. Hepcidin serum concentrations were also reported to increase in patients with renal failure in the line with increased severity of renal failure, which can cause the accumulation of hepcidin which culminates in anemia because iron deficiency. This Study was to analyze the correlation of anemia and hepcidin serum levels in patients end stage renal disease who undergoing regular hemodialysis with chronic hepatitis C.Methods : This study was an analytic observational with cross sectional design which was conduted on 24 patients end stage renal disease (ESRD) with chronic hepatitis C and 24 patients with ESRD without hepatitis who are undergoing regular hemodialysis theraphy in Haji Adam Malik Hospital, Medan in July – September 2016. All study subjects were examined for full blood count and hepcidin serum levels. The result of the iron status were recorded from the patient's medical record.Result : In this study, the mean hemoglobin was 8,15±1,44 g/dL, mean hematocrit 25,42±4,53%, median hepcidin levels 29,75 (4,92-359,49) in the patients ESRD with chronic hepatitis C and mean hemoglobin 8,21±1,50 g/dL, mean hematocrit 25,25±4,37%, median hepcidin levels 30,33 (11,65-141,53) in the patients ESRD without hepatitis. In Spearman's rho test was showed a positive correlation that significant between hepcidin and hemoglobin (r = 0,439, p = 0,032), hepcidin and hematocrit (r = 0,021, p = 0,024) in patients ESRD with chronic hepatitis C.Conclusion : This study showed there was a positive correlation between anemia and hepcidin serum levels in patients ESRD who undergoing regular hemodialysis with chronic hepatitis C.

Platelets have a central role in the pathogenesis of ACS. Immature Platelet Fraction (IPF) considered as a potential marker of the platelet activation process and platelet turnover process. Immature platelets have greater prothrombotic potential and aggregate more rapidly with collagen that affects platelet hemostasis potential that may contribute to the formation of thrombus. Therefore IPF is associated with the progression of coronary heart disease. MPV values reflect platelet activation. A cross sectional study was held in the clinical pathology laboratory of Dr. WahidinSudirohusodo Hospital Makassar during September-November 2016. 67 samples underwent and declared ACS by the physician. 67 patients with ACS were involved with a distribution of 30 patients STEMI (44.8%), 30 patients NSTEMI (44.8%), and 7 patients UAP (10.4%). Subjects are mostly male (73.1%) and young adult age (82.1%). There was significant difference of IPF value especially in STEMI group with mean 3,1 (p = 0,004) and no significant difference of MPV value in ACS group.Pearson correlation test showed there was positive correlation with weak strength of IPF and MPV values in ACS patients (p = 0.02, r = 0.388). There was a significant difference between IPF scores according to GRACE score (p = 0.005). Increased IPF value in STEMI group. The IPF score can be considered as a risk stratification of ACS patients replacing GRACE score. There was a positive correlation with weak strength of IPF and MPV value in ACS patients.

Abstract
Hypomethylating agent decitabine is being used in the treatment of certain types of leukaemia in combination with other anticancer drugs. Aberrant DNA methylation has been suggested to occur in pathological states including depression. Scarce data in male rats suggest antidepressant effects of decitabine. The main aim of our studies is to test the hypothesis that the inhibition of DNA methylation results in antidepressant effects in female rats. Before doing so, we decided to verify the effects of decitabine on DNA methylation in females. The findings demonstrate that the treatment with decitabine at the dose shown previously to inhibit DNA methylation in males, had no effect on total DNA methylation in two brain regions, namely the hippocampus and frontal cortex of female rats. In conclusion, the present study allows us to suggest that the effect of decitabine on DNA methylation in the brain is sex dependent.

Published: November 2019

Abstract
The scientific article is devoted to the study of parole from serving a sentence as the most important incentive institution of criminal and penal law. The study of this type of exemption from punishment revealed a number of moments not sufficiently regulated by the legislator, affecting the grounds for both the application and non-application of parole. As a basis for exemption from criminal punishment, not any assessment of the degree of correction of the convicted person was recorded, but only one that contributes to acceptable correction and positive resocialization of the offender without actually serving the unserved part of the criminal sentence. It is important that the legislator determines the inadmissibility of unjustified release of convicts from serving their sentences. The problematic issues of applying this institution are: the grounds for parole, which are not sufficiently clarified; situations concerning the objectivity of decision-making on granting or refusal to grant parole; the absence of a legislative specific specialized state body endowed with powers to control the behavior of those released on parole, capable of effectively implementing them. The article proposes solutions to these problems, providing a qualitative increase in the effectiveness of the application of the considered incentive institution.

In Indonesia there is no regulation about franchise. Same thing is also experienced of many state, for example English and Australian. No special regulation about franchising can be consedered to be good news or is bad news. The bad news is wth no special guidance, hence goodnesss of franchisor amd also of franchisee have to reckon on written agreement in cooperation contract. Irts meaning both parties have to neglectless and meticulous to the what agreed on. Protection of other decision which arrange an cooperation of Franchising represent the source of which whereas can be made by guidance do complied agreement have the basis for real correct and fair. Association of franhcising generally realese code of ethic of franchising.good news of inexistence regulation of area of franchising is goodness of franchisor and fracnhisee earn free compromise whateverly. As hold of legal fundament of agreement of franchise in Indonesia is freedom contract such as those which arranged in section 1338 KUH Perdata and by concidering conditions of section 1338 KUHP Perdata. Law contract in Indonesia embrace open system meaning that each and everyone is free to make all kinds of contract. In section 1338 KUH Perdata contained by the following rule all made contract lawfully will bind over them making it own. In the case conditions of 1320 section of KUH this Perdata is fulfilled by hence comand of section 1338 KUH Perdata. The making agreement act as code/law to all party.

The relation between legal subjects such as person or legal entity in a case, frequently generates dispute. Along with the complexity of social life, then, the more parties are involved in the dispute, the wider scope of the dispute case. One of the concerned dispute in the society is Industrial Relations Disputes that become the competence of Industrial Relations Court. Since 2015, The Act No. 2/2004 about Industrial Relations Dispute Settlement has enforced effectively, it still has many weaknesses, wether from practical or regulation aspects. The legal problems of its Act cause the settlement of Industrial Relations Dispute become less effective and efficient, also hamper the principle of constante justitite (principle of rapid, fair and easy trial). The research concluded that the practical/operational level of the Judges Panel in examining and adjudicating the cases of Industrial Relations Dispute in Industrial Relations Court of Samarinda, which tend to apply the general civil procedure law, from the examination of legal standing of the parties, exception, interlocutory decision, replik, duplik, writen proof, the witnesses, experts/professional witnesses, conclusion and verdict. This procedures only prolong the examination and trial process to settle the case of Industrial Relations Dispute. Therefore, the SOP (Standard Operational Procedure) of the settlement of Industrial Relations Dispute cannot be well-implemented yet as the mandate of the law.
