PERAN PERSEPSI ORANGTUA DALAM MENERAPKAN PENDIDIKAN SEKSUALITAS KEPADA ANAK USIA 9-12 TAHUN DI SD X

Pendidikan seksualitas pada dasarnya bermanfaat untuk membekali anak agar lebih siap menjalani perkembangan seksual, serta sigap menghadapi kekerasan seksual. Namun melalui wawancara kepada orangtua di SD X, mayoritas orangtua enggan menyampaikan informasi seksualitas kepada anak. Mereka ragu menjawab pertanyaan anak seputar seksualitas, bahkan beberapa orangtua mempertanyakan manfaat pendidikan seksualitas. Dapat disimpulkan kesadaran orangtua di SD X untuk menerapkan pendidikan seksualitas kepada anak masih kurang. Tujuan penelitian ini adalah mengetahui kontribusi persepsi orangtua terhadap penerapan pendidikan seksualitas kepada anak. Peneliti menggunakan Health-Belief Model yang terdiri dari perceived susceptibility, perceived severity, perceived benefit, perceived barrier, dan cues to action untuk menggali pandangan orangtua mengenai faktor-faktor yang mempengaruhi dirinya untuk menerapkan pendidikan seksualitas. Data diperoleh melalui kuesioner kepada 127 orangtua di SD X yang memiliki anak kelas 4-6 SD. Hasil analisis menunjukkan hanya perceived barrier (persepsi akan adanya hambatan) yang dapat memprediksi perilaku orangtua dalam menerapkan pendidikan seksualitas kepada anaknya (t = -.4.894, p < .05). Berdasarkan hasil penelitian, orangtua perlu difasilitasi untuk menghilangkan hambatan (barrier) dalam menyampaikan informasi seksualitas pada anak.

Adsorption of CO2, N2, CH4, and their mixtures on silicalite: A critical evaluation of force fields

The use of molecular simulation has been growing in the field of engineering, fueled not just by the advances in computational power but also on the availability of reliable software. One potential use of molecular simulation is related to the screening of materials for a specific application. The reliability of molecular simulation results depends on the trustworthiness of the force field used, which for engineering purposes should be as simple as possible. This work provides an evaluation of the potential accuracy cost of using simple generic force fields to predict the adsorption of CO2, CH4, N2 and their mixtures on MFI. We employed the GCMC technique for this investigation. Different models and force fields to describe adsorbates and adsorbent were tested. The force fields performances were estimated through comparison with available adsorption experimental data. Transferability was evaluated on the prediction of pure and mixtures adsorption on CHA, LTA and FER. The results showed that a simple force field presented similar performance when compared to a more sophisticated one.
Questions and avenues for lucerne improvement.

Six crucial questions for lucerne breeders are set up and discussed in relation to the available information. (i) Which width of adaptation? Genotype × location interaction is region-specific and may be wide enough to justify breeding for specific adaptation. Genotype × exploitation interaction requires contrasting plant types for mowing and intensive grazing. (ii) Can we breed very drought-tolerant varieties? One drought-tolerant landrace exhibited a drought-avoidance, water-conservation strategy based on limited root development, while large root featured material adapted to favourable environments and/or frequent mowing. (iii) Which selection scheme and variety type? Many schemes were proposed for synthetic varieties, but empirical or theoretical comparisons were limited in number and inference space. Non-additive genetic variation may be exploited by free hybrids (semi-hybrids) through procedures varying in complexity, possibly assisted by marker evaluation. Previous selection of exotic germplasm for adaptation is essential. (iv) How to improve the forage quality? Selection for modified stem morphology (increased internode number, decreased internode length) proved effective. Combined selection for forage yield and leaf/stem ratio seems also feasible. (v) Which opportunities for marker-assisted selection? Linkage maps for lucerne are available but useful markers for forage yield may be site-specific. Bulk segregant analysis is promising in breeding for stress tolerance. (vi) How to exploit genomic information from M. truncatula? This model species can help in developing markers and locating genes which control metabolic pathways, such as saponin content and composition. Information from M. truncatula on marker-trait association for forage yield or tolerance to abiotic stresses may be little exploitable.
Mobile Genetic Elements and Natural Gene Transfer in Rumen Microbial Ecosystem

As technology is going be modern different changes that occur in the nature become studied. Rumen microbes especially rumen bacteria play a vital role in utilization of ruminants feed. Without rumen microbe’s rumen can’t function correctly. So, when we feed our animals, we are also feeding rumen microbes which convert the plant fiber to VFA which used by ruminants as an energy source for maintenance and production. Through the process these microbes change in their genetic structure and function because of natural gene transfer which is mediated by movable genetic elements like bacteriophage, plasmid, transposons and other segments. In this review prokaryotes which include bacteria and archae have got large cover than eukaryotes because most significant changes in rumen are carried by those organisms. HGT is the way to perform this function because it enables bacteria to respond and adapt to their environment much more rapidly by acquiring large DNA sequence from other bacterium in a single transfer and mechanisms of bacterial gene transfer include transformation, transduction and conjugation. So this event has an impact on the microbe themselves, for the rumen ecosystem, the animal and the environment where these changes are related. These changes include antibiotic resistance, better conversion of feeds and effects in methane and ammonia production. Keywords: Horizontal Gene Transfer, Prokaryotes, Rumen.

Mechanisms of coexistence in diverse herbivore–carnivore assemblages: demographic, temporal and spatial heterogeneities affecting prey vulnerability

Simple models coupling the dynamics of single predators to single prey populations tend to generate oscillatory dynamics of both predator and prey, or extirpation of the prey followed by that of the predator. In reality, such oscillatory dynamics may be counteracted by prey refugia or by opportunities for prey switching by the predator in multi-prey assemblages. How these mechanisms operate depends on relative prey vulnerability, a factor ignored in simple interactive models. I outline how compositional, temporal, demographic and spatial heterogeneities help explain the contrasting effects of top predators on large herbivore abundance and population dynamics in species-rich African savanna ecosystems compared with less species-diverse northern temperate or subarctic ecosystems. Demographically, mortality inflicted by predation depends on the relative size and life history stage of the prey. Because all animals eventually die and are consumed by various carnivores, the additive component of the mortality inflicted is somewhat less than the predation rate. Prey vulnerability varies annually and seasonally, and between day and night. Spatial variation in the risk of predation depends on vegetation cover as well as on the availability of food resources. During times of food shortage, herbivores become prompted to occupy more risky habitats retaining more food. Predator concentrations dependent on the abundance of primary prey species may restrict the occurrence of other potential prey species less resistant to predation. The presence of multiple herbivore species of similar size in African savannas allows the top predator, the lion, to shift its prey selection flexibly dependent on changing prey vulnerability. Hence top–down and bottom–up influences on herbivore populations are intrinsically entangled. Models coupling the population dynamics of predators and prey need to accommodate the changing influences of prey demography, temporal variation in environmental conditions, and spatial variation in the relative vulnerability of alternative prey species to predation.
Validation of Wall Shear Stress Measurements Obtained with Magnetic Resonance Velocimetry

Wall shear stress acting on the vessel walls has been identified as an important factor for the initiation and development of cardiovascular diseases. In vivo measurements of the wall shear stress are usually conducted with Magnetic Resonance Velocimetry (MRV). Due to the limited spatial and temporal resolution, measurements in the near-wall region are challenging and the results are associated with high systematic and stochastic errors. Thus, an ongoing effort towards new post-processing methods to overcome this problem is observed. However, the underlying 'true' values of the wall shear stress are seldom known, inhibiting the evaluation of these methods. The present thesis is devoted to investigate this problem by conducting in vitro MRV measurements under well-known flow conditions and by providing reliable reference values of the wall shear stress. Flow situations have been selected in which wall shear stress values from laser Doppler velocimetry (LDV), analytical solutions, and results from numerical simulations are available as a reference. The in vitro experiments are performed in various flows with a step-by-step increase of the complexity, ranging from simple steady laminar pipe flows to unsteady transitional flows through complex geometries, representative for the human aorta. Extensive LDV measurements are presented, and the results of the velocity fields and wall shear stresses are compared to the MRV measurements. This thesis discusses possible systematic and random sources of errors in both measurement techniques. Additionally, it provides helpful advice for the practical measurement of the wall shear stress with LDV. In the course of this work a database has been established, which contains the MRV data as well as the corresponding reference wall shear stress values acquired under the well-known and controlled flow conditions. This database has been used by other research groups in a collaborative interdisciplinary project, which has the final goal of improving the estimation of the wall shear stress from MRV data.
Clinical profile of patients with supracondylar fracture femur

The mechanism of injury for most supracondylar fractures is thought to be axial loading with varus, valgus, or rotational forces. A bimodal distribution of high-energy trauma in younger patients and lower energy in elderly patients is typically seen with these injuries. However, higher-energy injuries in elderly patients are not uncommon. In younger patients, supracondylar fractures often occur following highenergy trauma related to motor vehicle or motorcycle accidents. In these patients there may be considerable fracture displacement, comminution, open wounds, and soft tissue injuries. This was a prospective longitudinal observational study with a follow up period of 6 months to 18 months. After obtaining approval from institutional ethics committee, 30 skeletally mature patients with distal fracture femur fractures, satisfying the inclusion and exclusion criteria were enrolled. Informed and written consent was taken from the enrolled patients. Supracondylar fracture of right femur more commonly affected than left in this present study group. Supracondylar fracture of right femur was seen in 17 patients making up to 56.7% of fractures and left sided femur was seen in 13 patients accounting for 43.3% of the fractures. None had bilateral fractures.
Azithromycin electrochemical detection using a molecularly imprinted polymer prepared on a disposable screen-printed electrode

Azithromycin (AZY) is among the antibiotics with the highest concentrations in aqueous matrices. Conventional wastewater treatment plants (WWTPs) do not fully remove this compound and it has been found in the environment. The health effects of AZY on humans and the environment are not yet understood. Therefore, the development of sensitive and selective analytical methods for AZY determination is important. In this work, an electrochemical molecularly imprinted polymer (MIP) sensor was developed for the quantification of AZY. The selection of the functional monomer was performed by molecular modelling using quantum mechanics calculations. The MIP was electropolymerized by cyclic voltammetry (CV) on a screen-printed carbon electrode (SPCE) using a solution containing 4-aminobenzoic acid (4-ABA) in the presence of AZY as a template molecule. The characterisation of the sensor was carried out using scanning electron microscopy (SEM), CV and electrochemical impedance spectroscopy (EIS). The analysis of AZY was performed by differential pulse voltammetry (DPV) in the linear range between 0.5 and 10.0 μM, with a limit of detection (LOD) of 0.08 μM (S/N = 3) and a limit of quantification (LOQ) of 0.3 μM (S/N = 10). The MIP sensor was found to have selectivity to recognise AZY molecules and was successfully applied in the analysis of tap water and water samples collected upstream of a WWTP output in the Ave River. The proposed sensor presents a simple, selective and environmentally friendly strategy for AZY determination in environmental water.
Generalized two-parameter estimator in linear regression model

In this paper, a new two-parameter estimator is proposed. This estimator is a generalization of two-parameter (TP) estimator introduced by Ozakle and Kaciranlar (The restricted and unrestricted two-parameter estimator, Commun. Statist. Theor. Meth. 36 (2007) 2707--2725) and includes the ordinary least squares (OLS), the ridge and the generalized Liu estimators, as special cases. Here, the performance of this new estimator over the TP estimator is theoretically investigated in terms of quadratic bias (QB) criterion and its performance over the OLS and TP estimators is also studied in terms of mean squared error matrix (MSEM) criterion. Furthermore, the estimation of the biasing parameters is obtained, a numerical example is given and a simulation study is done as well.
Overview of Optimization Models 2 and Algorithms for Train Platforming 3 Problem

In this paper, an overview of recent advances in the research on train 6 platforming problem (TPP) is presented. The TPP is usually the last problem 7 encountered in planning a railway system which occurs after a schedule of trains in 8 a railway network (train timetable) has been determined. It aims to map a given 9 train timetable to an existing station infrastructure. This process is critical as it 10 determines the feasibility of an optimally generated train timetable along a railway 11 line at station(s) to be visited by trains on the timetable. This optimization problem 12 is in most stations solved manually, and it is a time consuming and error-prone 13 process. Several computer programs are now being developed to aid infrastructure 14 managers and train operators as decision support systems in solving this problem. 15 This paper presents some of these solutions. However, due to variations in oper-16 ating policies of railway industries in different countries, several variants of this 17 problem exist in the literature. These variations could be seen in the solution 18 approach through the importance attached to level of service, safety of operations, 19 capacity utilization, etc. These variations and the various optimization techniques 20 adopted by researchers are also discussed in this paper. Currently, most models and 21 algorithms presented in literature are not ready for use as commercial systems. 22 Integrating such systems into real-life planning and operations is crucial for ef ﬁ cient 23 use of railway systems. 24
Design of DC‐side fault current limiter for MMC‐HVDC systems: Safety of the MMC along with frequency stability

A high voltage direct current system based on the modular multi-level converter (MMC-HVDC) is introduced as a suitable device for transmission of bulk powers over long distances. A pole-to-pole DC-side fault is a significant challenge for the MMC-HVDC system. Three main problems are the appearance of voltage spikes following a fast DC fault current break up, frequency instability due to insufficient inertia (networks such as renewable energy-based systems) and destruction of anti-parallel diodes within the MMC due to the high fault current. This study proposes a novel method for limiting DC fault current, improving isolation of the three-phase AC system from the DC-side. The suggested design employs high power resistors as virtual load such that continuity in active power flow will be kept on. Further, this prevents frequency deviation from exceeding the allowable limits. Also, transient over-voltages will be limited which are coming from stray inductances linked with electromagnetic effects of fault current level. Simulations and design practical issues have verified the validity of the proposal by using MATLAB/Simulink.
Genetic Diversity among Tomato (Solanum Lycopersicum L.) Genotypes

Tomato (Solanum lycopersicum L.) is an important member of Solanaceae family having chromosome number of 2n=2x=24. The probable ancestor of tomato is Solanum lycopersicum var. cerasiforme Bailey. It is originated in wild form in the Peru Equador region of Andes (South America) and it is grown in almost every corner of the world (Robertson and Labate, 2007). It is typically day neutral plant and is mainly selfpollinated, but a certain percentage of cross pollination also occurs (Depra et al., 2014). Tomato is universally treated as “Protective food” (Thamburaj and Singh, 2013). It is a very good source of income to small and marginal farmers and has a great nutritional value. Tomato is a rich source of minerals, vitamins and organic acids. It is a reservoir of International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 2 (2020) Journal homepage: http://www.ijcmas. com

Studies on Re-colonization of Microbial Populations in the Rhizosphere of Chrysanthemum after Soil Steaming

Among soil disinfestation practices, the application of steam to the soil prior to cultivation is one of the most commonly used management strategies. Growers use steam to effectively kill pathogens by heating the soil. Recently, growers of cut-flowers have noticed a reduction in flower size and weight, which they attribute to steaming the soil. Since shorter and lighter plants lose their commercial value, and therefore, are not accepted in the international market, there is a need to study in more detail the effects of steaming soil on plants and their microbial communities. The overall objective of this study was to determine the effect of consecutive steam application on the rhizosphere soil microbial community of chrysanthemum, and in particular the effects on specific bacterial groups (Pseudomonas spp. and Bacillus spp.). We hypothesized that repeated steam disinfestations cause irreversible changes in the soil community structure, leading to increases of bacterial groups that can be allelopathic for the plant, and that applications of plant growth-promoting rhizobacteria (PGPR) will remediate those effects. To examine the effects of steaming on the rhizosphere microbiota a greenhouse pot assay experiment was conducted using chrysanthemum cultivar golden Kent as a model plant. Rhizosphere soil samples were collected from chrysanthemum plants cultivated in soil that was subjected to steam once, steamed once with PGPR, steamed twice, and not steamed. Our results indicated that repeated steaming of soil changed the abundance of the microbial community, in particular increasing Pseudomonas populations. Although, the characterization of the functional traits of Pseudomonas cultured isolates showed that they produced differential levels of IAA and HCN, steaming the soil did not result in changes in functional traits of the Pseudomonas species
