UTILIZATION OF LOCAL CULTURAL AND ENVIRONMENTAL POTENTIAL AS A SOURCE OF LEARNING INDONESIAN IN A GLOBAL CONTEXT

Globalization brings changes in various sectors of life as a nation and state. Changes that occur in one community can cause changes in another society. The emergence of a change in the attitude of the young generation of Indonesia, known as the mileneal generation and generation z is the impact of changing attitudes of the younger generation in developed countries. The era of digital-based technology has become the arena of life for today's generation of generations. The rise of milleneal generation with a variety of innovations that have brought the impact of changes in services, including educational services. This phenomenon changes the context of the learning environment of students to be different from the previous context. The learning environment that includes school culture with its various ethos and characteristics as well as various educational policy factors has experienced a shift in the order and mechanism of its realization. The learning environment has direct and indirect effects on the learning process and outcomes. The learning process and results become meaningful if the learning activities are oriented to the potential and needs of students in present and future social life. Learning that involves the potential of the local environment and culture as a source and medium of learning is a challenge and a demand to make students able to build their character in accordance with the socio-cultural context of the community.

Enhanced Cash Flow Valuation in Real Estate Management by Integrating Innovative Materials and Risk Assessment

Environmental criteria have become a critical issue for the evaluation of projects and products, particularly for businesses with extensive life cycles. Sustainability criteria and project risk management are underexplored in real estate development, and thus endanger business survival. The aim of this article is to improve the understanding of uncertainties in the real estate industry by using a stochastic risk assessment approach and to broaden the risk assessment methodology. Thus, this article investigates the importance of material selection regarding external and project risk for real estate development. Aside from conventional projects, risks are analyzed for projects with high-quality materials (HQMs) that are characterized by environmental benefits. In following a mixed method approach, we began by conducting interviews with developers about the most important risks, and later incorporating these factors into a stochastic cash-flow model. Finally, we illustrated our findings in a case study. Overall, the highest risks were shown from resource prices and changing regulations, while the rankings of the two materials differ slightly; HQMs rank higher on the created risk index than conventional materials. The cash-flow model shows that conventional materials perform slightly better than HQMs, although uncertainties within the calculations are similar. The article contributes to risk management and decision-making for real estate projects by providing insights into the discussion and analysis of the financial performance of sustainable construction material and design that might be crucial for disruptive innovations. We present a model that integrates environmental and long-term effects in the cash-flow evaluation of real estate projects, thereby increasing managerial flexibility.
An Online Algorithm for VNF Service Chain Scaling in Datacenters

Built on top of virtualization technologies, network function virtualization (NFV) provides flexible and scalable software implementation of various network functions. Virtual network functions (VNFs), which are network functions implemented as virtual machines, are chained together to provide network services. Dynamic deployment of VNFs while satisfying incoming network traffic demand is the key to cost optimization of an NFV system. Besides considering server resource capacity and incoming traffic rates, an optimal scaling policy needs to strike a balance between VNF’s operational costs, the costs for maintaining VNF instances, and VNF deployment costs, additional costs when setting up new VNF instances on a server. This paper targets dynamic scaling of VNF instances in a cloud data center where multiple VNF chains are running. We propose an online scaling algorithm to adjust the deployment of VNF instances according to time-varying traffic demand, ensuring a good competitive ratio. Through theoretical analysis and trace-driven simulation, we demonstrate effectiveness of the proposed online VNF scaling algorithm.
Development of a Low-Power Microcontroller-Based Wrist-Worn Device With Resource-Constrained Activity Detection Algorithm

This article deals with the development of a resource-constrained activity detection algorithm for microcontroller-based wrist-worn devices. The various market available activity detection devices lack adequate agility and ease of use in certain applications, as they heavily rely upon computationally intensive algorithms to detect physical activity and step count. Therefore, by extension, they always need to stay connected with a smartphone that can perform these computations. To address this problem, this article introduces a standalone wearable device with the simplified algorithm for activity detection in a human being. The developed system consists of microelectromechanical systems (MEMS) triaxial accelerometer connected to a low-power microcontroller with a wrist anchor-able form factor. The step detection algorithm uses a moving average threshold filter to detect the change in acceleration data to identify specific events. A detailed comparative study considering power consumption and the step detection made between the developed device (with the resource-constrained algorithm) against market available devices shows that the average detection error of the developed algorithm is approximately 2% under various test conditions (i.e., walking, fast walking, and running) and has an accuracy of 94.96% for activity detection. This study reveals that the use of the proposed algorithm for activity detection not only brings down the cost of the overall device but also reduces the power consumption (< 45.7 mW) with a minimal covering size (12.56 cm2) for the wearable part that can extend the application area of such devices.
Design of constant output voltage DC-AC inverter for batteryless solar PV system

This paper introduces a DC-AC inverter design that operates stand alone to deliver power from solar photovoltaic (PV) to the load directly without going through the battery. In batteryless solar PV, the output voltage of solar PV always varies according to solar irradiation, temperature, so that it becomes a challenge in modelling DC-AC inverter with constant output voltage. The design consists of a boost converter, h-bridge switching and driver, and LC filter to generate sinusoidal ac voltage as output to load. To ensure a constant inverter output voltage, the design equipped by a close loop PI controller based on voltage control mode. The design modelled and simulated by PSIM. PV dc input was set variation according to the irradiation value (W/m2) and the output connected to a load that has rated voltage of 220 Vac and 3.4 A of nominal current. The results show that in the irradiation variation 600-1500 W/m2, the inverter was able to maintain the output voltage of 220 Vac ± 0.91%, 50 Hz which is still in the voltage range based on standard. The efficiency produced by DC-AC inverter 97.7 % at 600 W/m2 and 83.6 % at 1500 W/m2.
Does pre-diagnostic loss to follow-up among presumptive TB patients differ by type of health facility? An operational research from Hwange, Zimbabwe in 2017

Introduction While there are many studies assessing the pre-treatment loss to follow-up (LFU) among tuberculosis patients in public sector, there is no evidence from private-for-profit health sector and pre-diagnostic LFU from Zimbabwe. We aimed to assess the gaps in the cascade of care of presumptive TB patients registered during January-June 2017 in different types of health facilities in Hwange district, Zimbabwe. Methods This was a cohort study involving review of routine programme data. Pre-diagnostic LFU was defined as the proportion of presumptive TB patients not tested using sputum microscopy or Xpert MTB/RIF. A log binomial regression was done to assess factors associated with pre-diagnostic LFU. Results Of 1279 presumptive TB patients, 955(75%) were tested for TB and 102(8%) were diagnosed as having TB. All TB patients were started on treatment. Pre-diagnostic LFU (overall 25%) was significantly higher among patients visiting private-for-profit health facilities (36%), local self-government run council health facilities (35%) and church-run mission health facilities (25%) compared to government health facilities (14%). Pre-diagnostic LFU was significantly higher among patients in rural areas (30%) compared to urban areas (18%). Type of health facility was associated with pre-diagnostic LFU after adjusting for HIV status and area of residence. Conclusion While pre-diagnostic LFU was high, there was no pre-treatment LFU. Pre-diagnostic LFU was especially high in private-for-profit and council health facilities and rural areas. National TB Programme should take immediate steps to improve access in rural areas and support the private-for-profit and council health facilities by improving sputum collection and transport.
Detection of plant water stress using leaf spectral responses in three poplar hybrids prior to the onset of physiological effects

ABSTRACT The negative impact of water stress on forest and tree plantation productivity has been the focus of many investigations. However, moderate water stress that can decrease productivity and is difficult to detect, has received less attention. Therefore, we designed a greenhouse experiment where the main objective was to test the efficacy of published biochemical and water stress indices along with physiological traits in detecting moderate water stress at leaf scale. Potted saplings of three hybrid poplars ((Populus × canadensis) × P. maximowiczii, Populus × canadensis and Populus × generosa ‘Boelare’) were subjected to moderate water stress. During the experiment we recorded (i) the biomass accumulation and allocation to leaves, stem, and roots; (ii) Net CO2 assimilation rate (A) and stomatal conductance (g s) and (iii) Spectral biochemical and water indices. Results indicate that moderate water deficit had a negative impact on biomass accumulation, but no change was detected in physiological traits. Nitrogen and chlorophyll contents also remained unaffected. Spectral biochemical indices failed to detect differences between treatments, whereas water stress indices succeeded. We also have identified unique wavelengths in the shortwave infrared region of the spectrum that proved sufficiently sensitive on their own to detect moderate water deficit. The results were not influenced by a genotype effect, suggesting that these unique wavelengths could be responding to a general rather than a species-specific leaf feature, thus widening opportunities for the early detection of plant stress, particularly moderate water deficit.
The effect of virginiamycin and black pepper (Piper nigrum L.) extract on performance of broiler chicks.

An investigation was carried out to determine the effect of virginiamycin and black pepper extract on performance of broiler chicks. A total of 240 day old (Ross 308) broiler chicks were divided into three groups. Treatment diets were basal diet (T1), basal diet with 200 g/ton virginiamycin powder (T2) and basal diet with 2 mg/ml black pepper aqueous extract (T3). Data was collected on feed intake, body weight gains and feed conversion ratio. Blood samples were analyzed for triglyceride, HDL, LDL and antibody titre against Newcastle disease vaccine. In addition, intestinal microbial populations for Escherichia coli and Lactobacillus (Cfu/g) were also investigated. The results showed that carcass characteristics improved significantly (P<0.05) in T2 and T3. Serum cholesterol profile and antibody titre improved in experimental diets (P<0.05) compared to the control. The intestinal population of E. coli decreased and Lactobacillus increased significantly in treated groups. In conclusion, the aqueous extract of black pepper produced better results compared to control and virginiamycin treatment.
Expression of the anti-apoptotic bfl-1/A1 gene is regulated by the Epstein Barr virus nuclear antigen 2(EBNA2)

The ubiquitous and oncogenic human herpesvirus Epstein-Barr virus (EBV) establishes a latent infection and promotes the long-term survival of the infected host cell by targeting the molecular machinery that controls cell fate decisions (apoptosis, proliferation and differentiation). These host-virus interactions are likely to play a crucial role in the development of EBV-associated malignancies mcludmg African endemic Burkitf s lymphoma, nasopharyngeal carcinoma, Hodgkin’s disease and lymphoprohferative disorders in immunodeficient individuals We have previously shown that (1) EBVmfected Burkitt’s lymphoma cell lines exhibit elevated levels of expression of the antiapoptotic bfl-\ gene (also known as A l) compared to their uninfected counterparts, (11) ectopic expression of Bfl-1 can protect a Burkitt’s lymphoma (BL) cell line from apoptosis induced by serum deprivation (D’Souza, B , Rowe, M and Walls, D 2000 J Virol, 74, 6652) and (m) the EBV Latent Membrane Protein 1 (LMP1) stimulates bfl-1 promoter activity through interactions with components of the cellular Tumour Necrosis Factor Receptor (TNFR/CD40)-signallmg pathway by a mechanism which includes an essential role for the transcription factor NFkB (D’Souza et al, submitted) Bfl-1 is an anti-apoptotic protein of the Bcl-2 family, whose preferential expression in hematopoietic and endothelial cells is controlled by inflammatory stimuli. This study reports the novel finding that the EBV nuclear antigen 2 (EBNA2), a second major effector of phenotypic change m EBV-infected cells, can independently upregulate bfl-1 mRNA levels m BL cell lines. This thesis presents the novel finding that EBNA2 regulates bfl-1 promoter activity through interactions with components of the cellular Notch signalling pathway EBNA2-mediated /ram-activation of bfl-1 is dependent upon its ability to bind CBF1 (a nuclear component of the Notch signalling pathway) and involves a novel CBF-l-hke binding site on the bfl-1 promoter This EBNA2-mediated effect on bfl-1 is modulated by other EBV latent proteins that are known to co-operate with EBNA2 (EBNA-LP) or which have been shown to interact with the CBF1 -co-repressor complex (EBNA3A, 3B, 3C and RPMS) These findings are relevant to our understanding of EBV persistence, its role m malignant disease, and the B cell developmental process

Debemos cuantificar los diámetros de las cavidades derechas en relación con la superficie corporal

Background: The evaluation of the right heart cavities represents a challenge for echocardiography, given the impossibility of their approach to a geometric model. Moreover, there are no recommendations on the need to adjust right heart dimensions to body surface area. Objective: The aim of this study was to establish the relationship between right heart chamber dimensions and body surface area in a population with no evidence of cardiopulmonary disease. Methods: The study included patients attending the echocardiography laboratory for a regular health examination. Patients with cardiac disease, right or left ventricular dysfunction, significant valve diseases, known pulmonary disease or pulmonary systolic pressure ≥45 mmHg were excluded from the study. Patients’ affiliation, weight (kg), height (meters), and body surface area (m2) data were recorded. Right heart measurements were based on guideline recommendations. The population was distributed in quartiles according to body surface area (25%-50%-75%-100%). Simple regression analysis was performed between each dimension of the right heart and body surface area. Results: A prospective, consecutive, observational and descriptive cohort study was performed including 1,045 patients with the following characteristics: mean age 41±15.1 years, 53% men, mean weight 77.4±19.6 kg, height 1.69±0.09 and BSA 1.89±0.87 m2. Significant differences were observed in each of the variables according to the distribution by quartiles. A positive correlation was demonstrated between all right heart dimensions and body surface area. Conclusions: Body surface area is an important determinant of right heart dimensions measured by echocardiography. We therefore suggest the use of measurements indexed by body surface area, since it could influence clinical decision making.
Measurement of thermodynamic temperature between 5 K and 24.5 K with single-pressure refractive-index gas thermometry

We describe measurements of thermodynamic temperature in the range 5 K to 24.5561 K (the triple point of neon) using single-pressure refractive-index gas thermometry (SPRIGT) with 4He. In the wake of the May 2019 re-definition of the kelvin and its associated mise en pratique, the main purpose of the work is to provide values of T–T 90, the discrepancy between thermodynamic temperature and that of the International Temperature Scale of 1990 (ITS-90). The link to ITS-90 is made via calibrated rhodium-iron resistance thermometers. Innovations required to reach the level of accuracy required for meaningful measurements (uncertainty in T–T 90 less than the expected deviation) include the suppression of temperature oscillations in a cryogen-free cryostat, a pressure stabilization scheme based on a non-rotating piston balance, modelling of the hydrostatic head correction and refinements of the measurement of microwave resonances in a quasi-spherical copper resonator. The accuracy of measurements varies from 0.05 mK to 0.17 mK and is competitive with that of all previous ones in this temperature range using other techniques. The improvement stems partly from the new techniques used for the new definition of the kelvin as well as ab initio calculations of the thermophysical properties ofgaseous 4He. In addition to confirming the validity of SPRIGT as an accurate, easier-to-implement alternative to other low-temperature primary thermometry techniques (e.g. acoustic gas thermometry) yet with scope for improvement, the results should provide important input data for any future revision of ITS-90.
A Design-Based Learning Approach for Fostering Sustainability Competency in Engineering Education

This paper provides and illustrates a design-based learning (DBL) approach for fostering individual sustainability competency in engineering education. We performed two studies with engineering students in typical educational activities. The first study helped students perform a topic-specific design task in the practicum unit of a sensor technology course, which compared the performance of the DBL approach and conventional passive learning approach. The second study guided students to develop innovative projects for participating in the "Internet Plus" Innovation and Entrepreneurship Competition (IPIEC). To validate the proposed approach, stakeholder questionnaires and performance evaluations were implemented. The results show that the DBL approach was viable for sustainability competency teaching in terms of learning demand and teaching procedure. We found that students in the DBL group gave more prominence in the individual competencies, such as system-thinking, multidisciplinary applications, and collaboration. These findings suggest that applying the DBL approach to train sustainability competency in engineering education is beneficial for promoting students’ abilities in dealing with challenges involved in sustainability practice.
An Overview of the Relationship between Psychological Capital and Entrepreneurial Orientation of Startup Companies

Start-up is a driving force to promote technological innovation, create new jobs, and support economic growth. Throughout the ongoing progress of developing Vietnam’s economic growth model, the start-up and improving labor productivity issues have been playing an increasingly crucial part. In this study, the authors examined the relationship between psychological capital and business orientation of start-up companies to provide a model for optimal utilization of these companies’ resources. It has been observed that the intermediary role of employee’s engagement in the relationship between psychological capital and organizational commitment within the companies is genuinely crucial and that effective and systematic psychological capital intervention will provide a solid foundation for the improvement of labor productivity.
Agrobacterium-mediated transformation of indica ricecultivars using binary and superbinary vectors

The Agrobacterium-mediated transformation system was extended to two indica cultivars: a widely cultivated breeding line IR-64 and an elite basmati cultivar Karnal Local. Root tips and shoot tips of seedlings, and scutellar-calli derived from mature seeds showed high-efficiency Agrobacterium tumefaciens infection and stable transformation. In addition to the superbinary vector pTOK233 in Agrobacterium strain LBA4404, almost equally high levels of transformation were achieved with a relatively much smaller (13.1 kb) binary vector (pCAMBIA1301) in a supervirulent host strain AGL1. In both cases, as well as in both cultivars, while 60–90% of the infected explants produced calli resistant to the selectable agent hygromycin, 59–75% of such calli tested positive for GUS. A high level (400 μM) of acetosyringone in the preinduction medium for Agrobacterium and a higher level (500 μM) in the cocultivation medium was necessary for an enhancement in transformation frequency of the binary vector to levels comparable to a superbinary. Hygromycin-resistant calli could be produced from all the explants used. Transformants could be regenerated for both cultivars using the superbinary and binary vector, but only for calli of scutellar origin. In addition to the molecular confirmation of hpt and gus gene transfer and transcription, absence of gene sequences outside the transferred DNA (T-DNA) region confirmed absence of any long T-DNA transfer.
