Dampak Keberadaan Universitas Islam Negeri Raden Intan Lampung Terhadap Kondisi Ekonomi di Kecamatan Sukarame, Kota Bandar Lampung

Regional development is an effort made to encourage economic development in achieving prosperity. Welfare is influenced through supply and demand. One of the supply and demand is the existence of educational facilities. Educational facilities are able to provide positive externalities. The education facility in question is the UIN RIL college located in Sukarame District, Bandar Lampung City. Before changing its status to UIN RIL, the existence of the campus had not affected the surrounding economic activities. However, since the increase in status from 2017 to 2022, slowly there have been many developments such as the conversion of land that was previously empty land such as rice fields and shrubs to turned into built-up land such as stalls, grocery stores, photocopies, and so on. This study aims to determine the impact of the existence of UIN RIL on the economic conditions of the people in Sukarame District. This research was conducted by considering two conditions, namely the conditions in 2017 before the increase in status and the current conditions after the existence of UIN RIL until now, namely 2022. This research uses a quantitative deductive approach that is oriented based on variables obtained from the literature review. Data collection techniques using questionnaires and observation. The results showed that the existence of UIN RIL had positive and negative impacts on economic conditions. These positive impacts include increasing employment opportunities, increasing basic and additional income, and increasing asset ownership. While the negative impact is the increase in the amount of public spending. This study also identified the level of impact through scalogram analysis which resulted in Sukarame and Way Dadi Sub-Districts being areas with the highest economic impact due to the existence of UIN RIL.

Late Adverse Events of Radiotherapy with Concomitant Cisplatin and the Response to Them

Dysphagia is a late adverse event of radiotherapy with concomitant Cisplatin (CDDP-RT), and patients with advanced laryngeal cancer who undergo CDDP-RT have an impaired swallowing-related quality of life. Dysphagia induced by CDDP-RT has two major causative factors: delayed or untimely swallowing reflexes caused by xerostomia or oral or oropharyngeal mucosal sensory disturbance and a decrease in laryngeal perception, laryngeal elevation disorder, inadequate relaxation of the cricopharyngeal region, and other problems with the swallowing function due to the effects of RT on the larynx, pharyngeal contractile muscles, and other parts of the neck. Oral healthcare and dysphagia rehabilitation are considered essential for patients requiring CDDP-RT, and such a support system needs to be established at the facility in question. Future clinical trials (JCOG1912) will help clarify whether or not reducing the dose in the prophylactic irradiation area can mitigate late adverse events while maintaining treatment efficacy. Induction chemotherapy may be able to reduce the extent of irradiation of the tumor area and the area of prophylactic irradiation. However, this has not yet been proven, and further studies in larger cohorts are needed.

A Harmonized Information Security Taxonomy for Cyber Physical Systems

Cyber physical systems (CPSs) are found in many aspects of daily life, and they control and protect energy production, manufacturing and even healthcare. Due to long lifecycles and the use of legacy technologies, its associated security comes with many challenges. Security taxonomies are useful to classify and communicate security-related information and elements. Despite the existence of numerous taxonomies, they are fragmentary, limited to only specific lifecycle phases or cover only specific aspects. A harmonized taxonomy must be applicable to all lifecycle phases of the CPS. This paper presents well-established taxonomies that are combined into a single comprehensive and harmonized taxonomy and allows application throughout the different lifecycle phases. Application of the taxonomy to real-world scenarios requires a consistent implementation methodology. The use of the harmonized taxonomy methodology is demonstrated by applying it to an actual incident case study. The taxonomy is used to identify information security gaps through its implementation in the industrial facility in question. The identified gaps are then addressed as part of the security lifecycle of the CPS. The harmonized taxonomy can be expanded to apply it to industries with specific requirements.

Life cycle assessment of a wind farm in Turkey.

The aim of this study is to investigate the environmental impacts of a full-scale wind farm using life cycle assessment methodology. The facility in question is an onshore wind farm located in Turkey with a total installed capacity of 47.5 MW consisting of 2.5 MW Nordex wind turbines. Hub height and rotor diameter of the wind turbines are 100 m. The system boundary is defined as material extraction, part production, construction, operation and maintenance and decommissioning phases of the wind farm. The functional unit is 1-kWh electricity produced. Environmental impacts are mainly generated by manufacturing and installation operations. Steel sheet usage in tower manufacturing is the main contributor to abiotic depletion of fossil resources, acidification, eutrophication, global warming and marine aquatic ecotoxicity potentials. Apart from ozone layer depletion, end-of-life phase decreases the environmental impacts due to metal recycling. Metal recycling ratio scenario results show that when the recycling ratio decreases from 90 to 20%; increases of 110%, 102%, 92% and 87% are observed in acidification, terrestrial ecotoxicity, marine aquatic ecotoxicity and global warming potentials, respectively. In the baseline, the main parts which are manufactured in Germany are transported by sea to Turkey. Transportation scenario involves shifting the manufacturing of main parts to Turkey then transporting these parts by trucks to the farm. This conversion causes increases of 31%, 35% and 27% in abiotic depletion of fossil resources, freshwater aquatic ecotoxicity and global warming potentials, respectively, while causing decreases of 11% and 4% in acidification and eutrophication potentials generated by transportation activities, respectively.

Web-based language learning and speaking anxiety

Foreign Language Speaking Anxiety (FLSA) is known to negatively affect the performance of foreign language learners. Among the four language skills, speaking is the most anxiety-provoking skill. We investigated the presence of FLSA in Indonesian vocational high school students and we tested whether web-based language learning might help to reduce speaking anxiety, in particular when the facility in question is equipped with Automatic Speech Recognition (ASR). A mixed methods research was employed to investigate FLSA in 573 vocational high school students. A subset of them (n = 167) was selected to participate in two ASR-based web-experiments using www.iloveindonesia.my.id and NovoLearning. We additionally interviewed 11 of the students who participated in these web-experiments and five English teachers. The results showed that students indicated a moderate-to-serious level of FLSA, that they evaluated the learning websites positively, and believed that web-based language learning could alleviate their speaking anxiety. The interviews revealed that students felt less anxious when speaking in front of the ASR-based websites compared to speaking to peers or people. In order to evaluate the real effectiveness of ASR-based learning websites, future studies should investigate actual improvement of learners’ speaking skills over a longer period of time.

Оценка объемов образования РАО от вывода из эксплуатации с использованием информационных моделей

At present time, intensive efforts on the decommissioning of nuclear facilities are actively performed with the efficiency improvement viewed as a key task as regards their planning. Since the management of the generated radioactive waste is considered as a main component of the decommissioning cost, reliable estimate of the generated RW amounts is essential. The paper seeks to demonstrate an approach to assessing the amounts of decommissioning RW based on the data from comprehensive engineering and radiation survey of a facility in question using digital information models.

DEVELOPMENT OF CORRELATION AND REGRESSION MODELS OF ELECTRIC ENERGY INDICATORS OF THE EQUIPMENT WITH CONTINUOUS NATURE OF PRODUCTION

The article presents an analysis of the use of correlation-regression analysis, which is based on the methods of mathematical statistics and probability theory in the study of the power consumption of enterprises with equipment of continuous production. On the basis of the annual power consumption schedule of the electric steel-smelting shop in a monthly time section, mathematical models have been developed for the power consumption parameters. And also, on the basis of statistical data with the use of a mathematical method, mathematical expressions were obtained for the electric power consumption and the specific consumption for the main equipment of the electric steel-smelting shop. In order to assess the adequacy of the developed mathematical models, mathematical models of the total and specific consumption of their power consumption are compared with actual data. The comparison results show high reliability of the power consumption modes of the main equipment of the facility in question. The analysis of the values of forecast errors with low error rates determines the adequacy of the developed mathematical models of the parameters of power consumption in terms of power consumption and specific consumption for the main equipment of the electric steel-smelting shop. In this regard, they can be used to determine the predicted values of the parameters of power consumption in electric steelmaking equipment.

ESTIMATION OF THE SIZE OF STAGNATION ZONES ON THE TERRITORY OF THE PROPANE-BUTANE TANK FARM AIMED AT INCREASING THE SAFETY OF THE FACILITY

The safety of the territory is directly dependent upon the propane-butane storage and use technology. The paper reveals the efficiency of FlowVision software-based computational fluid dynamics technology (CFD) in modeling the stagnation zones and the behavior of fuel-air mixture (FAM) cloud within the territory of storage facilities. Propane-butane storage tank farm storage was selected as the object of research. CAD SolidWorks was used in the design of his three-dimensional model. Methods using "dispersed heavy gas models" have been developed. It is based on the numerical solution of three-dimensional fluid and gas dynamics equations, including the laws of conservation of mass, momentum (the Navier-Stokes equation) and constitutive equation. Recommendations on changes to be implemented during the design stage of tank farms with propane-butane mixture have been developed in order to increase facility safety in case of equipment depressurization. It is known that buildings, located on the territory, impair the airflow, resulting in the presence of large stagnant zones. It has been established that as a result of the movement of air flow through the territory of the tank farm, the maximum areas of stagnation zones are observed with the north wind and the minimum – with the southeast wind. Using the three-dimensional modeling techniques and finite volumes the stagnation zones in the tank farm were computed for different wind directions and measurement heights, enabling a comprehensive assessment of the situation at the facility in question and development of series of safety-increasing measures.

Integration of point cloud data and hyperspectral imaging as a data gathering methodology for refurbishment projects using building information modelling (BIM)

PurposeBuilding information modelling (BIM) is a digital representation of the physical and functional characteristics of a building. Its use offers a range of benefits in terms of achieving the efficient design, construction, operation and maintenance of buildings. Applying BIM at the outset of a new build project should be relatively easy. However, it is often problematic to apply BIM techniques to an existing building, for example, as part of a refurbishment project or as a tool supporting the facilities management strategy, because of inadequacies in the previous management of the dataset that characterises the facility in question. These inadequacies may include information on as built geometry and materials of construction. By the application of automated retrospective data gathering for use in BIM, such problems should be largely overcome and significant benefits in terms of efficiency gains and cost savings should be achieved.Design/methodology/approachLaser scanning can be used to collect geometrical and spatial information in the form of a 3D point cloud, and this technique is already used. However, as a point cloud representation does not contain any semantic information or geometrical context, such point cloud data must refer to external sources of data, such as building specification and construction materials, to be in used in BIM.FindingsHyperspectral imaging techniques can be applied to provide both spectral and spatial information of scenes as a set of high-resolution images. Integrating of a 3D point cloud into hyperspectral images would enable accurate identification and classification of surface materials and would also convert the 3D representation to BIM.Originality/valueThis integrated approach has been applied in other areas, for example, in crop management. The transfer of this approach to facilities management and construction would improve the efficiency and automation of the data transition from building pathology to BIM. In this study, the technological feasibility and advantages of the integration of laser scanning and hyperspectral imaging (the latter not having previously been used in the construction context in its own right) is discussed, and an example of the use of a new integration technique is presented, applied for the first time in the context of buildings.

Применение методологии искусственного интеллекта для формализации результатов обработки нечеткой информации

One of the distinctive features pertinent to the present-day conditions under which the power plant equipment operate is the necessity to run it in variable modes, as a result of which certain changes occur in the equipment technical state with time. These factors have generated the need of solving, on a priority basis, a number of unresolved matters concerned with creating models for decision-making and state recognition proceeding from power plant diagnostics with the use of fuzzy information for identifying the equipment state and managing the equipment recovering processes. It should be noted, however, that there is no unified methodological approach to obtaining the relevant information for diagnostic purposes in solving such problems under the conditions of fuzziness and inhomogeneity of initial information about the actual equipment state and its residual life. As a result, the existing methods for shaping data and knowledge in performing an analysis of data and in making managerial decisions are not identified and are not interconnected with their mathematical models. In addition, they are aimed at solving separate tasks and are not always able to ensure that the equipment set model’s parameters are consistent with the actual state of the facility in question. At the same time, the shift that was done in the power industry from the policy of planned and preventive repairs to the policy of repairs according to the actual technical state has resulted in that a higher responsibility has to be undertaken by those who make decisions in determining the repair scope and timeframes, and, accordingly, more stringent requirements are imposed on the quality of diagnostic models. As a consequence of its having been made without doing proper methodical background work, such a shift has lead a situation in which the diagnostic and the decision-making models turned to be inadequate due to the use of information about the equipment state that contains uncertainties. At the same time, recent years have seen a drastically grown interest in various aspects of the intellectual management problem, in particular, the intellectual management by technologies according to a hybrid principle. One of the main areas involves the use of techniques developed within the framework of fuzzy systems and cognitive neural sciences: fuzzy sets, fuzzy logic, fuzzy modeling and management, semantic memory organization, fuzzy mathematics, artificial neural networks, pattern recognition, data processing by human neurons and brain, human consciousness, mind, memory, and artificial life. The article presents the results from extending the range of practical applications of the fuzzy and hybrid system techniques as applied to the technologies of estimating the state of complex technical systems (including power systems), especially under the conditions of data processing and using cognitive neural sciences.

On the possibility for precision measurements of differential cross sections for elastic proton–proton scattering at the Protvino accelerator

Elastic-scattering data were analyzed, and it was concluded on the basis of this analysis that precisionmeasurements of differential cross sections for elastic proton–proton scattering at the accelerator of the Institute for High Energy Physics (IHEP, Protvino, Russia) over a broad momentum-transfer range are of importance and topical interest. The layout of the respective experimental facility detecting the scattered particle and recoil proton and possessing a high momentum-transfer resolution was examined along with the equipment constituting this facility. The facility in question is able to record up to a billion events of elastic proton–proton scattering per IHEP accelerator run (20 days). Other lines of physics research with this facility are briefly discussed.

Sustainable Strategies of Urban Planning

Ecosystem degradation and environmental urban development create a new trend in the context of global ecological crisis. This trend involves the need to shift urban facilities to sustainable development, which in turn is linked to the necessity to modernize urban environment in the view of comfort, economy, and ecological compatibility. The design of sustainable cities plays a natural catalytic role for change and improvement of the environment quality. This paper analyses sustainable development strategies and methodological principles of sustainable architecture in particular, which served as a basis to define a set of core principles of establishing architectural solutions of energy-efficient buildings such as urban, architectural and planning, design concepts as well as the principles of the use of renewable energy. The project of energy-efficient school in Gaziantep, Turkey, being the sustainable architectural model, was used as an example to show the application of the methodology and demonstrate the comprehensive integration of engineering, architectural and energy-efficient solutions into the facility in question.

Frozen in perpetuity: 'abandoned embryos' in Canada.

The matter of ‘abandoned embryos’ arises when surplus IVF embryos are frozen and stored for later use. If the fertility clinic or storage facility in question does not have clear direction about what to do with these embryos, and/or payment for storage ceases, and/or the embryo providers cannot be reached, the embryos raise an ethical and practical challenge. On the one hand, there is a commitment to respect the autonomy of embryo providers to determine what should happen to their frozen embryos. On the other hand, there are weighty reasons why fertility clinics and storage facilities do not want responsibility, potentially in perpetuity, for other people’s frozen embryos. This article examines the matter of ‘abandoned embryos’ – the emergence of the term, its use in policy and law, and its implications in the Canadian case. We demonstrate that despite an intricate legislative framework, there are important gaps that leave fertility clinics and storage facilities in the tenuous position of discarding ‘abandoned embryos’ without clear authorization, or storing them indefinitely. We argue that clarity in consent procedures coupled with flexible time limits on embryo storage provide an approach that can best serve the interests of all involved.

Reputation Dynamics in Networks: Application to Cyber Security of Wind Farms

Wind power is becoming an increasingly important technology for electric power generation in many power systems around the world. A typical wind farm consists of a relatively large number of turbines under some form of decentralized control. In this context, a cyber-attack to wind power infrastructure may not only cause immediate physical damage to the facility in question, but may also threaten the stability of the power system in which this facility operates. In this paper, we present a novel distributed algorithm aimed at detecting cyber-attacks in a wind farm. The cyber-attacks considered take the form of adversarial manipulation of different turbine-specific control logic parameters. The proposed algorithm relies on the operational dynamics specific to wind farms namely that turbines that are relatively close are subject to similar wind patterns and hence must be in similar control states most of the time. This can be seen as a wisdom of the crowd effect: the true is the of the majority of turbines in physical proximity when only a few have been compromised. In the proposed algorithm, each turbine in the farm periodically shares information regarding their own control state with neighboring turbines through a dedicated wireless channel. We test the performance of the proposed algorithm in a simulation test-bed based on Denmark's Horns Rev wind farm. The results indicate that iterative reputation or trust re-allocation enables a distributed identification of affected turbines under a wide array of cyber-attack scenarios.

A free pricing strategy at a major tourist attraction: The Case of West Lake, China

Abstract This study analyzes an uncommon tourism attraction pricing phenomenon in China, known as “free West Lake”. West Lake Scenic District in Hangzhou is a World Heritage Site in China׳s most prosperous eastern region. Here, the admission fee was progressively removed and free access was introduced. This paper uses Chinese newspaper reports, official documents and academic articles to explore the evolution of the pricing policy and its consequences for visitor use and government finances, with implications for other attractions in China and elsewhere. This novel pricing initiative resulted in an initial economic loss to the local government but eventually broadened the economic base, reduced the environmental pressure on certain sensitive heritage sites, and enhanced tourists׳ experiences, residents׳ quality of life and the city׳s reputation, providing novel insights into public resource management in China. The case highlights the importance of adopting a broad perspective on admission pricing, as the implications may extend beyond the narrow confines of the facility in question.

Application of an adjoint neighborhood‐scale chemistry transport model to the attribution of primary formaldehyde at Lynchburg Ferry during TexAQS II

AbstractDuring the 2006 Second Texas Air Quality Study (TexAQS II) field study, ambient mixing ratios of formaldehyde (HCHO) up to 52 ppbv were observed at Lynchburg Ferry in the Houston Ship Channel on the morning of 27 September 2006. These elevated mixing ratios coincided with a flare event during a sequential planned shutdown of a petrochemical facility ~8 km from the monitoring site. An adjoint version of the Houston Advanced Research Center (HARC) neighborhood air quality model was used to perform 4‐D variational inverse modeling of industrial emissions of HCHO and other ozone precursors based on Lynchburg Ferry observations. The simulation employed a horizontal domain size and grid resolution of 8 km × 8 km and 400 m, and was conducted for a 1.5 h period (8–9:30 A.M.) during which the highest HCHO concentrations were recorded. The event emissions of ethene and propene computed by the inverse model are consistent with the largest estimated emissions for the facility in question derived from the Solar Occultation Flux technique during TexAQS II. Moreover, the computed peak flare emissions of HCHO during the shutdown event were around 282 kg/h, which is less than but comparable in magnitude to the largest area‐wide total (primary plus secondary) formaldehyde flux from the Houston Ship Channel measured by Differential Optical Absorption Spectroscopy during TexAQS II. The estimated flare event emissions of primary formaldehyde are roughly 50 times larger than HCHO emissions from flares used in routine operations, as inferred from remote sensing and/or real‐time in situ measurements during the 2009 SHARP campaign.

Evaluating the Importance of Business Location Factors: The Influence of Facility Type

AbstractThis study examines two important issues concerning the evaluation of business location factors. First, in contrast to many analyses that seek to determine the influence of a single factor or set of factors on site selection, this study aims to measure the relative importance of a wide range of factors. Second, it investigates the extent to which the perceived importance of a given location factor varies based on the type of facility in question. While there is a substantial amount of research devoted to identifying industry‐specific location factors, little is known about the influence that facility type has on the assessment of location criteria. Drawing on original survey data collected from real estate professionals in the U.S., we found significant differences in the mean ratings for more than half of the 39 location factors on the basis of facility type. In particular, “corporate/office” respondents were significantly more likely than “manufacturing” or “retail” respondents to assign higher ratings to “quality‐of‐life” location factors, such as crime rates, amenities, housing, and schools. We discuss the implications of these findings for future research on location theory.

A sale-leaseback transaction: Is it right for your business?

A sale-leaseback is defined as the sale of an owner-occupied property to a real estate investor followed by leasing back space from the new owner. The goal for the vendor essentially is to raise capital while retaining use of the facility in question, while the purchaser is happy to acquire stable, long-term cash flow; however, sale-leasebacks are not this simplistic and, in fact, are not suitable for every corporation. It is key to understand, not only the company's real estate, but also its overall corporate strategy, before determining if such a transaction is suitable. Understanding whether a sale-leaseback transaction could work for a corporation requires a robust financial model, a look at the pros and cons, approach and rationale, and more.
