Authors: Suryono Chrisna Adhi , Indardjo Agus 
Published: November 2022

The Semarang and Tegal coastal waters are traditional fishing ground areas. However, the increasing use of coastal areas for various activities will increase pollutants in the coastal waters. Heavy metals are pollutants that always appear in waters and accumulate in marine organisms. These study aims to determine As and Hg metals contained in the tissues of several marine organisms caught on the coast of Semarang and Tegal, Central Java. The analysis of As and Hg concentrations in organismal tissues using ICPMS. The results showed that As and Hg were found in biota such as white shrimp (P. merguensis), blue crab (P. pelagicus), shellfish (A. inaequivalvis) and gastropods (H. ternatanus). Arsenic concentrations in the four biotas caught in Tegal (1.6 – 5.3 ppm) and Semarang (2.58 – 4.9 ppm). Meanwhile, Hg metal (0.02 – 0.15 ppm) in Tegal and (0.034 – 0.15 ppm) in Semarang. The concentration level of As based on the biota caught in the Tegal waters are sequentially Shellfish > White shrimp > Gastropods > Blue swimming crab. Meanwhile, the concentration of Arsenic in the biotas in Semarang waters are sequentially shellfish > white shrimp > blue crab > gastropods. However, Hg metal in the biota obtained in these two areas is very low Pesisir Semarang dan Tegal merupakan daerah penangkapan perikanan tradisional. Namun dengan semakin meningkatnya pemamnfaatan wilayah pesisir untuk berbagai kegiatan akan meningkatkan polutan dalam perairan. Logam berat merupakan polutan yang selalu muncul dalam perairan dan terakumulasi organisme laut. Penelitian ini bertujuan untuk mengetahui logam As dan Hg yang terdapat dalam jaringan beberapa biota yang ditangkap pesisir Semarang dan Tegal Jawa Tengah. Analisa konsentrasi As dan Hg dalam jaringan organisme menguunakan ICPMS. Hasil penelitian menunjukan logam As dan Hg ditemukan dalam biota seperti udang putih (P. Merguensis), rajungan (P. pelagicus), kerang bulu (A. inaequivalvis) dan gastropoda (H. ternatanus). Konsentrasi Arsen di keempat biota yang ditangkap di Tegal (1,6 – 5,3 ppm) dan Semarang (2,58 – 4,9 ppm). Sedangkan logam Hg (0,02 – 0,15 ppm) di Tegal dan (0,034 – 0,15 ppm) Semarang. Tingkat konsentrasi logam As berdasarkan biota yang tertangkap di perairan Tegal secara berurutan Kerang bulu > Udang putih > Gastropoda > Rajungan. Sedangkan konsentrasi Arsen dalam biota di perairan Semarang secara berurutan Kerang bulu > Udang putih > Rajungan > Gastropoda. Namun logam Hg dalam biota yang didapat di kedua daerah tersebut sangat rendah.

Abstract
This paper describes the Networked Energy Systems Emulation Center – DLR-NESTEC – a platform for research on power grids of the future. The DLR-NESTEC consists of a large number of networked power electronic components with which real hardware can be emulated using a real-time simulation system. The grid networking is realized via cable emulators. The laboratory works with real physical power flows and has a connected load of 800 kVA. In addition to the emulators, real network components can be integrated into the laboratory. The sector coupling is addressed by the coupling of charging infrastructure of electric cars as well as the integration of electricity-controlled heating systems. In addition, hydrogen technologies can be integrated. The laboratory is controlled by a SCADA system coupled to high-resolution measurement equipment. With the help of DLR-NESTEC, various future questions regarding robust and safe operation sector-coupled energy networks can be addressed – for instance the operation of a grid structure with a high share of controllable loads without a superordinate control.

Published: November 2022

Abstract
Clinical laboratories play a vital role in the healthcare system. Objective medical data provided by clinical laboratories supports approximately 60–70% of clinical decisions, however, evidence supporting this claim is poorly documented and laboratories still lack visibility, despite their indisputable impact on patient care and public health. The International Federation for Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Outcome Studies in Laboratory Medicine (TF-OSLM) was recently developed to support directed research evaluating the role of laboratory medicine on clinical outcomes. Establishing and documenting this evidence is key to enhance visibility of the field in the eye of the public and other healthcare professionals together with optimizing patient outcomes and health care system operations. In this review, we discuss four areas that exemplify the contribution of laboratory medicine directly to patient care. This includes high-sensitivity cardiac troponin (hs-cTn) and N-terminal pro-B-type natriuretic peptide/B-type natriuretic peptides (NT-proBNP/BNP) for the diagnosis and prognosis of myocardial infarction and heart failure, respectively, and procalcitonin for the management of sepsis and antibiotic stewardship. Emerging markers of traumatic brain injury and the role of laboratory medicine in the fight against the COVID-19 pandemic are discussed along with an introduction to plans of IFCC TF-OSLM.

Published: November 2022

AbstractObjectivesVitamin D plays an essential role in neonatal skeletal development and maternal weight gain during pregnancy. We aim to study the association between vitamin D status, maternal weight, and materno-neonatal bone metabolism parameters.MethodsFrom January to June 2017, we conducted this cross-sectional study among 103 pregnant women (21–42 years old) and their singletons. The levels of serum 25-(OH)D, PTH, P1NP, OC, and CTX were measured for mothers and neonates (cord blood). Serum vitamin D and OC were measured using chemiluminescence and two-site immunoradiometric assay, respectively. Meanwhile, P1NP, CTX, and PTH were measured by ELISA.ResultsThe average serum vitamin D levels from mothers were 15.1 ng/mL during pregnancy and 16.2 ng/mL in the umbilical cord. At baseline, vitamin D deficient mothers were more likely to have higher PTH (36.4 vs. 18 pg/mL; p=0.029) and lower P1NP levels (90 vs. 92.5 ng/mL; p=0.026). Also, vitamin D deficient status was associated with lower fetal weight (3,293 vs. 3,358g; p=0.019). Maternal weight was significantly correlated with P1NP (65.86 vs. 109.35; p=0.001) and OC (14.52 vs. 18.24; p=0.038), as well as cord vitamin D level (13.31 vs. 18.46; p=0.039) among normal vs. overweight women. No significant differences were found for the correlation between maternal weight and fetal parameters except for fetal weight which significantly increased with the increase in maternal weight (overweight vs. obese women=3,280 vs. 3,560; p=0.06).ConclusionsMaternal vitamin D status is associated with maternal and neonatal bone metabolism parameters as well as maternal and neonatal weight.

Published: November 2022

As computer networks become more critical to enterprises, it is inevitable that efficient security policies are designed, case in point: wireless networks, in order to effectively ensure the confidentiality, availability, and integrity of the data traversing these networks. The primary objective of this paper is to appropriately simulate an enterprise network, and evaluate the threats, and possible mitigation approaches applicable. An analysis of an enterprise WLAN (Wireless Local Area Network) was carried out, to identify relevant vulnerabilities, and possible countermeasures against these threats. The primary threats analysed were those possible by an external adversary. Upon identification of said threats, a security model was developed, so as to improve enterprise network security, and ensure the levels are optimum. In addition, a number of the principles involved are applicable to non-wireless networks. Keywords: WLAN, Wireless, Security, WPA 2, IEEE 802.11.
Cardinality Enhancement of SAC-OCDMA Systems Using New Diagonal Double Weight Code
Authors: Imtiaz Waqas Ahmed , Ahmed Nasim 
Published: November 2022

Optical code division multiple access (OCDMA) provides another dimension to multiple access systems, in which each user is assigned a unique code. This allows each subscriber to simultaneously access the medium without any contention. However, simultaneous access of multiple users introduce multiple access interference (MAI) which primarily deteriorates the performance of OCDMA systems. This paper proposes a new code called diagonal double weight (DDW) code to elevate the performance and cardinality of spectral amplitude coding (SAC) OCDMA systems. Performance of our proposed code is evaluated using comprehensive analytical analysis followed by simulation analysis. Examination of bit error rate shows that DDW code along with single photodiode detection technique provides efficient performance, with added benefits of simplified design, large cardinality and ease of implementation.

Published: November 2022

Cloud defines a new age of computing solution that provides services to customers with its unique features of agility and multi-tenancy. As the critical resources are hosted at cloud provider’s end, security is a big challenge in cloud computing. If the cloud environment is compromised and attackers get the access of core data centers, the availability of the critical resources becomes a big concern for the service consumers. Denial of Service and Distributed Denial of Service kind of attacks are launched towards cloud environment to make the resources unavailable for legitimate users. In this paper we propose a fuzzy logic based defense mechanism that can be set with predefined rules by which it can detect the malicious packets and takes proper counter measures to mitigate the DDoS attack. Also a detailed study of different kind of DDoS attack and existing defense strategies has been carried out. Keywords: DoS, DDoS, fuzzy logic.
Modeling Poisson Error Process on Wireless Channels
Authors: Csóka Tibor , Polec Jaroslav 
Published: November 2022

Burst error modeling has seen extensive research and progress over several decades evolving into ever more complex modeling techniques used today. This paper analyzed usefulness of the most prominent generative and descriptive (analytical) methods. Data containing error bits and packets from real wireless transmission has been used to obtain statistical information about error burst and gap behavior in the channel and various generative and descriptive modeling techniques were applied to model the error process with the goal of establishing advantages and disadvantages of each technique. Generative methods were represented by the commonly implemented Elliot’s model with parameters calculated using a generalized algebraic form and descriptive methods were represented by one of the most flexible exponentially shaped distributions with regard to parameterization and heavy-tailed function modeling - gamma distribution, and lastly a technique represented by Markov modulated Poisson process (MMPP-2) producing second-order hyper-exponentially distributed characteristics. Results of the experiments were highly in favor of Elliot’s and MMPP-2 model demonstrating possible application of MMPP-2 model in application to commonly observed exponentially-shaped error process on the wireless channel.

Published: November 2022

Presently employed Internet Protocol (IP) stack possesses number of architectural problems. The issues like Dual/Overriding role of IP addresses, mobility, multi-homing etc are the limitations for the infrastructure oriented networks which even have support of Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), Network Address Translation (NAT) servers, etc. Such issues are extremely complex to handle in the case of multi-hop wireless ad hoc networks which lack the support of any infrastructure component. The contemporary research direction for the improvement of present Internet architecture mainly focuses on the use of real identifiers instead of IP addresses for host identification in the network. However, the proposed architectures mostly discuss the infrastructure oriented network models and minimal research has been conducted in the direction of proposals for ad hoc networks. In this paper we provide a thorough discussion on the practical usage issues of IP based ad hoc network implementation. In order to resolve the present limitations of ad hoc networks, we describe an implementation of a novel identifier based ad hoc network protocol stack and architecture known as IDHOCNET (Identifier based ad hoc network). The architecture proposes a novel paradigm of identifier based applications for multi-hop wireless ad hoc environment. The proposed system further provides backward compatibility to support co-existence with IP based applications. As a proof of concept, the architecture has been implemented on Linux platform with WiFi interfaces. Various practical scenarios with architectural insight are presented to demonstrate the practicability of the proposed approach.
A energy-conserving predictive preemptive multipath routing protocol for adhoc networks: a lifetime improvement
Authors: Ali cherif Moussa , Boukli Hacene Sofiane 
Published: November 2022

Mobile device are widely used today in MANETs, due to their rich functionality. However, route failure may occur due to lower receive signal strength, mobility, congestion and device failures. Also, the battery life of these devices is very limited and deploying high resource consuming applications such as streaming on these mobile devices, is a challenging task. It is extremely important to efficiently use of the contained resources on these devices when they participate in a mobile ad hoc network. In this paper, we propose an optimization of the cross-layer networking mechanism. Our work focuses on MAC and routing layers of the OSI stack. We propose a cooperation of the routing layer with the MAC layer power-control technique to decrease the energy consumption in transmission within adhoc networks. We propose an energy-conserving multipath routing protocol for adhoc networks lifetime improvement protocol called E-PPAOMDV (Energy aware Predictive Preemptive AOMDV). This protocol is based on new metric to preserves the residual energy of nodes and balances the consumed energy to increase the network lifetime. Also, we propose a mechanism based on Newton interpolation, to distinguish between both situations, failures due to congestion or mobility, and consequently avoiding unnecessary route repair process. The E-PPAOMDV was implemented using NS-2. The simulation results demonstrate the merits of our proposed E-PPAOMDV. Our proposal improves the performance of mobile ad hoc networks by extending the lifetime of the network and decreasing the average consumed energy with approximately 1 to 3%, while the average end-to-end delay is reduced by 33%, normalized routing load by 20 to 27%; also, increasing the packet delivery ratio with approximately 2-10% and the throughput with 5% when compared with AOMR-LM.

BACKGROUND: Relatives caring for an epilepsy patient play a significant role in the care system and maintaining the well-being of the chronically ill and often suffer from significant stress.
AIM: The aim of the study was to reveal the relationship of psychological distress, basic beliefs and perceptions of family relationships in relatives taking care of children and adults with epilepsy.
MATERIALS AND METHODS: The study involved 62 relatives caring for patients with epilepsy, 44 relatives of children (mean [SD] age, 34,64 6,73 years) and 18 relatives of adults (mean [SD] age, 48,72 10,99 years). The Symptom Checklist-90-Revised (SCL-90-R), the World Assumption Scale and the Family Environment Scale was used as an assessment tools. Also semi-structured interview for assessing socio-demographic and clinical characteristics was applied.
RESULTS: The results of the study revealed significant similarities of the studied groups both in the explication of the psychopathological symptoms and in perception of their own personality, the surrounding world and intra-family interaction. Informal caregivers of such patients demonstrates significant variability and severity of psychopathological symptoms. And their perception of themselves and the surrounding world is characterized by the faade tendencies that act as psychological protection that prevents the catastrophizing of the subjective assessment of the situation associated with the chronic disease of a loved one.
CONCLUSIONS: The study demonstrated the need to develop specialized psychotherapeutic interventions aimed at reducing the level of psychological distress in informal caregivers of patients with epilepsy. During the development and carrying out of such interventions, it is important to take into account the subjective assessment of caregivers available life situation, as well as his/her personal values and attitudes that largely determine the severity of psychopathological symptoms.
