Published: March 2023

An Air Traffic Controller(ATC) is a person responsible for the proper Take-Off and Landing of an Aircraft from the runway, and for relaying continuous vital information back and forth from Pilots. The proposed ATC will automate this entire process to reduce human-generated errors and save costs. The entire system will be made using Artificial Intelligence and will use Natural Language Processing and Artificial Neural Networks to create a human-like, but a better-prepared system. The model needed to create the ATC, can be trained on already available crucial flight data. The data must include flight take-off and landing time, along with altered time based on weather, climate and other physical factors. The back-end system of the ATC, can be then made to work on this trained model, and produce correct and calculated flight path and timings for the take-off and Landing. The system will do an automatic Pre-flight checkup, based on weather and other clear-sky conditions, such as birds and overhead flights. If there are no problematic conditions, a flight can be allowed to take-off. Similarly, a flight can be allowed to land, based on a clear runaway and good weather conditions. Also, the system will use Artificial Neural Networks, to pan out an optimized flight path for the aircraft to follow, so as to reach a particular destination by avoiding extra air traffic, and saving fuel.The AI-inspired ATC will also be responsible, to tackle problems faced by pilots based on their requests, voice & mood conditions, which will be processed using a customized NLP Component. Implementing the proposed AI-inspired Air Traffic Controller can significantly reduce errors, save costs, and reduce the overhead of extra time in panic situations.

Published: March 2023

Aerospace manufacturing is improving its productivity and growth by expanding its
capacity for production by investing in new tools and more equipment to provide
additional capacity and flexibility in the face of widespread supply disruptions
and unpredictable demand. However, the cost of such measures can result in
increased unit costs. Alternatively, productivity and quality can be improved by
utilizing available resources better to reach optimal performance and react to
emerging disruptions and changes. Elastic Manufacturing is a new paradigm that
aims to change the response behavior of firms to meet sudden market demands
based on automated analysis of the utilization of the available resources, and
autonomous allocation of capacity to use resources in the most efficient manner.
Through digitalization of the shopfloor, streaming data from equipment enables
companies to identify areas for improvement and boost the efficiency without
large capital expenditure. Additionally, the impact of supply chain disruptions
can be reduced through demand forecasting, inventory optimization, early warning
systems, and flexible reallocation of resources; all of which could be managed
elastically through integrated data collection in the supply chain. This paper
describes how smart factories with more flexibility and resilience can be
achieved with semantically-enhanced quality analytics, maintenance solutions,
and automated key performance indicator monitoring. An example of measuring the
capacity utilization rate, by following the measurement of multiple KPIs from a
shopfloor level using data from a real aerospace project is demonstrated showing
the significance of monitored process performance.
Investigation of the effect of some polar organic solvents on the leaching and dissolution kinetics of chalcopyrite in hydrogen peroxide and sulfuric acid solution
Authors: Taha Osman Abdelraheem Mohamed , Agacayak Tevfik
Published: March 2023

ABSTRACT. The effect of acetic acid and ethanol as polar aqueous solvents on sulfuric acid with hydrogen peroxide as an oxidant was studied. A small amount of these polar aqueous solvents significantly improved the copper leaching recovery. The leaching parameters such as temperature, stirring speed, H2O2 concentration, solid/liquid ratio, H2SO4 concentration and particle size were examined. About 76.33% as highest Cu extraction was gained with 2 M H2O2, 600 rpm stirring speed, 50 °C temperature, 1 M H2SO4, 240 min of the reaction and 75 x 53 µm particle size fraction. Further experimental tests were carried out when the stirring speed, solid-to-liquid ratio (S/L), particle size, H2O2 concentration, temperature and H2SO4 concentration were kept constant to investigate the effect of ethanol and acetic acid concentration in the range of 0–2 M. The experimental results proved that the copper extraction recovery reached to 99.03% in 180 min of the reaction with 2 M acetic acid. While 2 M of ethanol increased copper extraction recovery up to 100% in 90 min of the leaching time. The dissolution reaction found to be described by mixed kinetic model and activation energy of 54.37 kJ/mol. Addition of acetic acid and ethanol suggested reaction controlled by diffusion across product layer.

Published: March 2023

ABSTRACT. For lump and nanocobalt sulfate (CoSO4) in pure water, the affiliation and thermodynamic association characteristics were measured at 298.15, 303.15, 308.15, and 313.15 K. Based on the bulk and nano CoSO4 molar conductance, estimates were made for the parameters of the solvation, such as the activity coefficient, free energy of association, enthalpy of association, association constant, and entropy of association. We discussed about each of these solvation parameters. Two stoichiometric complexes were formed by the interaction of bulk and nano CoSO4.7H2O with fuchsin acid: 1:1 and 1:2 In the case of 1:1 (CoSO4.7H2O/fuchsin acid) compared to 1:2 (fuchsin acid in pure water as solvent), the complex Kf and ∆Gf are higher, indicating simpler complex formation. The temperature increase resulted in a drop in the formation constants. The complexation's negative ∆Gf values demonstrate that the process of complex synthesis was spontaneous and that the temperature improved the spontaneity.

Effect of Pymarc with NPK 17-17-17 and intra-row spacing on soil and bush bean (Phaseolus vulgaris L.) yield in volcanic highland, Rwanda
Authors: Munyampundu Emmanuel , Rukangantambara Hamud , Habimana Sylvestre
Published: March 2023

Bush bean is the poor families’ meat in Rwanda and grown in many corners of the country. However, unevenness application of organic and inorganic  amendments brought soil degradation including soil toxicity or deficiency and low bush bean production. The objective of this study was to evaluate the  effect of pymarc rates with NPK and spacing on Soil organic matter, physical parameters and bush bean yield parameters in volcanic highland. The design  was RCBD with four replications and the experiment had two factors; Pymarc rates: P0(control), P1(250Kg ha-1 NPK), P2(10 tons ha-1 pymarc+250  Kg ha-1 NPK), P3(15 tons ha-1 pymarc+250Kg ha-1 NPK) and P4(20 tons ha-1 pymarc+250Kg ha-1 NPK) and spacing levels: S1(40cm x15cm), S2(40cm x  20cm) and S3(40cm x 30cm). Results showed that, highly significant difference (p<0.01) was in treatments and greatest improvements were brought out  by P2S1 with lowest Bd(0.95 g cm-3), highest WHC(38.34 %) and porosity(42.18 %) at harvesting with mean yield of 3.03 t/ha compared to P0S3 with least  values of studied attributes. Highest SOM content was found out in P4S3 and P3S1 of 9.84 % and 9.75 % sequentially. The correlation analysis results  between WHC, Porosity, SOM and yield varied from weak to strong (0.4>r, r>0.7), significant (p<0.05) and positive while the same relationship but negative  existed between Bd and other parameters. Therefore, sowing the bush bean at the spacing of 40cm x15cm with application of 10t  ha-1 pymarc+250 Kg ha-1 NPK 17-17-17 could be recommended to agronomists and farmers from volcanic highland in Rwanda for bush bean optimum  yield.
Communicating as Community: Examining Power and Authority in Community-focused Environmental Communication through Participatory Action Research in the Ourimbah Creek Valley

Published: March 2023

In this paper we argue that the making of meaning is a powerful creative act that occurs within social and cultural contexts where there exists a multi-directional flow or interconnected relationships within a system of communication (McIntyre, 2012). This little explored set of ideas echoes Rogers and Kincaid’s earlier systems-based proposition that “the communication process has no beginning and no end, only the mutually defining relationship among the parts which give meaning to the whole” (1981, pp. 55-56). Similarly, Ali et al. have suggested that the “holistic, relational, interactional, and process-nature of Indigenous ontologies and epistemologies resemble the tenets of systems theory” (2022). With this theoretical foundation in place – located in complex and interconnected systems rather than a Western reductionist worldview (Gadgil et al, 1993) – this project uses action research as a methodology, reframing participants from ‘subjects’ to co-researchers. We assert that “people’s right and ability to have a say in decisions which affect them and claim to generate knowledge about them” (Reason and Bradbury, 2011, p. 9) can empower them on multiple levels to enact change (Freire, 1970; Reason, 2005; Reason and Bradbury, 2011). From this position, “we acknowledge our lives are in connection with multitudes of other beings” (Weir, 2012, p. 4) and that many of the key concepts of this project are rooted in Indigenous knowledges. As such, traditional notions of top-down power are challenged in favour of an even and diffuse power distribution within a communication act (Foucault, 1980). The specific act of communication under examination is found in the Department of Planning, Industry and Environment (DPIE) and various communications to the public concerning the necessity of preserving threatened species. The DPIE’s perception of a lack of public awareness led to the planning and execution of a pilot programme to engage public understanding and acceptance of the issues faced (PRIA, 2011). The project team, including DPIE and Darkinjung Local Aboriginal Land Council, set out to create a participatory community of inquiry in the Ourimbah Creek Valley, located on the Central Coast of New South Wales. This valley is home to 48 threatened fauna species and at least 12 threatened flora species and is critical to their survival. To engage with this action-research approach, residents were invited to a workshop which included a site visit, a bush-food inspired morning tea, and a collaborative art-making activity to share knowledge and build community awareness of and encourage stewardship of two threatened species. This paper reports on the findings of this action-research process.
47 c Assessment of Willingness to Pay for Sustainable Ecotourism Development in the Salt Range Wetlands, Punjab Pakistan
Authors: Ghous Muhammad , Siddiqui Saima
Published: March 2023

Wetlands are the source of vital ecosystems which provide human societies with essential and extremely valuable life-supporting functions. The rapid population growth and resultant exploitation of lands, water bodies, and forests have badly influenced wetland resources. Wetlands are non-market goods as they do not have market value. So, it is important to evaluate these resources economically to identify their significance. Therefore, this study aims to identify the visitors’ willingness to pay for the economic valuation of Salt Range wetlands comprised of Kalar Kahar, Uchali, Jhalar, Khabeki, and Namal Lakes. A qualitative method was used to gather relevant information from the respondents by using a questionnaire. By applying the willingness to pay (WTP) technique it was found that about 85.34% of tourists were agreed to visit these lakes because of their naturalness. Similarly, the mean WTP in Kalar Kahar lake was PKR. 1808, in Uchali lakes was PKR.1820 while in Namal lake it was PKR. 1848. It is concluded that all the lakes are equally important and economically valuable for the tourists as there was a frictional difference in mean WTP. It is suggested that these lakes should be conserved for future generations to sustain the long-term economic benefits for the concerned stakeholders through the initiation of ecotourism.

Published: March 2023

This study demonstrates the reservoir investigation of the Cretaceous Lower Goru “C” sand interval using exploratory well data from the middle Indus basin of Sindh. The petrophysical parameters including volume of shale, effective porosity, and water saturation of the investigated reservoir interval were calculated. The shale volume calculation results in 30–35% of non-clean (shale) lithology, which is high as compared to Sawan-01 and Sawan-08 wells. The effective porosity ranges from 12–16%, while the average value of water saturation in the complete interval of “C” sand falls in the range of 50–60%. However, certain zones with relatively lower water saturation values of around 30-50% are also observed. These zones are considered better pay zones in comparison to the other intervals. A “gas effect” phenomenon observed on cross plots represents the area of neutron-density cross-over indicating the presence of lighter hydrocarbons in this reservoir zone interval.

Natural and anthropogenic indulgence in the form of industrialization, urban sprawl, and population increase deplete the water resources that entails immediate consideration. So, contemplating this need for eco-rehabilitation, drinking water quality predicted in contemporary research for surface and groundwater in proximity of Precambrian rocks (Chenab Nagar, Punjab) revealed poor water quality status. Physical parameters (EC, TDS, and temperature), chemical (pH, carbonates, bicarbonates, chlorides, and heavy metals) and microbiological (total coliforms, fecal coliforms, and the absence or occurrence of E. coli) distinctiveness of water were determined in forty-two samples, collected from study area. The mean values of pH, EC, TDS, carbonates, bicarbonates, chlorides, and temperature for water samples fluctuated discretely in all months. Likewise, heavy metals depicted an increasing trend as the concentration of cadmium and lead was high among all analyzed metals. Microbiological study shows that large number of the samples

Published: March 2023

One of the persistent organic pollutants (POPs) utilized globally between the 1930s and 1980s was polychlorinated biphenyls (PCBs). Even though their usage has been severely constrained, a lot of PCBs are still present in the environment, including soils and air. This local, national, international and governmental organizations regarding polychlorinated biphenyls and how can resolve and treat the problem sustainably. This can be achieved if seriously working on degrading persistent organic pollutants, especially polychlorinated biphenyls biologically via thorough research and sound implementation. The methods opted for remediation by the use of choosing suitable types of microorganisms and plants. These methods are practically active for the identification of the source, concentration level and effects on the ecosystem. It would help in developing appropriate strategy and data generation in formulating the inventories for the management of polychlorinated biphenyls in the future. It is also noted through numerous research that polychlorinated biphenyls are also found in human blood commonly analyzed by indicator congeners such as PCB 138,153, 180, and in air and soil markers of PCBs pollution include PCB congeners 28, 52,101,138,153 and 180 as well. The methods and mechanisms described for degrading the persistent pollutant in this research review the solutions for mitigating PCB pollution in an environment. The best option is to strictly ban it in Pakistan or weightage its usage with its multiple benefits and disadvantages. Promote biological treatment if the payback is healthy and environmentally sustainable.

From the point of view of one social organization a rational choice about an alternative for an action in a definite security environment is made on the basis of defining optimum of possible numbers of alternatives among which a choice is being fulfilled towards putting into practice a system of criteria in order to compare options of alternatives. For that reason taking a decision connected with a choice about a strategy for management of counteraction to encroachments on social organization is one of the most difficult management tasks that has ever been carried out on the circumstances of complex and dynamic fast-changing security environment.
Modelling the Utility of Body Temperature Readings From Primary Care Consults for SARS Surveillance in an Army Medical Centre
Authors: Chen Mark IC , Tan Iain BH , Ng Yih-Yng
Published: March 2023

Introduction: There is interest in surveillance systems for outbreak detection at stages where clinical presentation would still be undifferentiated. Such systems focus on detecting clusters of syndromes in excess of baseline levels, which may indicate an outbreak. We model the detection limits of a potential system based on primary care consults for the detection of an outbreak of severe acute respiratory syndrome (SARS). Materials and Methods: Data from an averaged-sized medical centre were extracted from the Patient Care Enhancement System (PACES) [the electronic medical records system serving the Singapore Armed Forces (SAF)]. Thresholds were set to 3 or more cases presenting with particular syndromes and a temperature reading of ≥38o C (T ≥38). Monte Carlo simulation was used to insert simulated SARS outbreaks of various sizes onto the background incidence of febrile cases, accounting for distribution of SARS incubation period, delay from onset to first consult, and likelihood of presenting with T ≥38 to the SAF medical centre. Results: Valid temperature data was available for 2012 out of 2305 eligible syndromic consults (87.2%). T ≥38 was observed in 166 consults (8.3%). Simulated outbreaks would peak 7 days after exposure, but, on average, signals at their peak would consist of 10.9% of entire outbreak size. Under baseline assumptions, the system has a higher than 90% chance of detecting an outbreak only with 20 or more cases. Conclusions: Surveillance based on clusters of cases with T ≥38 helps reduce background noise in primary care data, but the major limitation of such systems is that they are still only able to confidently detect large outbreaks.

Published: March 2023

Oronasal fistula is one of the unfortunate consequences of cleft palate surgery. This can be done after palate surgery in patients with cleft palate, defined as an abnormal connection between the oral and nasal cavities. Multiple systems have attempted that classification. It can be a small, symptomatic or asymptomatic fistula that needs correction. Its speed varies greatly depending on many factors. Both surgical and non-surgical methods (the advantages and disadvantages of each should be considered) are available for correction, and there are combination therapies that help improve surgical outcomes. Platelet-rich fibrin (PRF) is a novel Generation platelet concentrate, very easy to prepare and handle without the use of biochemicals. Its production is dependent on the accumulation of platelets that release cytokines and growth factors. Enriched with growth factors, this hemostatic plug is easy to prepare and operate. Adapted for soft and hard tissue healing. It is used in various fields of dentistry, especially oral and maxillofacial surgery. Reports on the role of PRF in repairing oronasal fistula closure are sparse in the literature, especially in relation to other soft tissue flaps.

Optimal Investment and Financing Decisions Under Cost Uncertainty
Authors:   PhD student in National Taiwan University, Wu I-Shin
Published: March 2023

In this paper, we employ the real options approach to study the impact of cost uncertainty on a firm’s optimal investment and financing decisions. The firm owns a perpetual right to an irreversible investment project, and the firm’s goal is to determine the optimal investment timing and level of coupon payments when the investment cost jumps upward at a random time. We find that the optimal investment threshold and level of coupon payments decrease with the jump intensity and the magnitude of the jump. The cost uncertainty gives the firm a stronger incentive to accept projects with risky cash flows. Furthermore, we examine the conflict of interests between the share- and bond-holders. We show that the debt overhang distortion and the asset substitution incentive decrease with the cost uncertainty. However, the effect of cost uncertainty on the incentive of asset substitution reverses in the region of low operating profits

Model-based abundance estimates for bottlenose dolphins off southern Spain: implications for conservation and management
Authors: Canadas A. , Hammond P. S.
Published: March 2023

An EU-funded Life project was initiated off southern Spain in 2002, with the objective of developing a Conservation Plan for bottlenose dolphins in the area. Baseline information and monitoring of abundance and distribution is needed to determine if the conservation objectives are met in the long-term. To estimate abundance, 12,568km of non-systematic line transects conducted from 2000 to 2003, with 72 sightings, were analysed using spatial modelling methods. Transects were divided into 4,575 small segments (average 2.8km) with similar values for sightability conditions and environmental variables. The point estimate of bottlenose dolphin abundance in the area was 584 dolphins (95% CI=278-744). The same method was applied to investigate changes in abundance since 1992 in the eastern section of the research area, where most dolphins were concentrated, stratifying by three groups of years. Point estimates were 111 dolphins for 1992-97, 537 for 1998-2000 and 279 for 2001-03. The higher abundance between 1998 and 2000 corresponded with the observation of an ‘immigrant’ group of dolphins in these years. These results highlight the importance of long-term studies to understand natural variation in abundance in a specific area subject to conservation activities.

The incidental catch of harbour porpoises (Phocoena phocoena) in the gillnet fishery of the Estuary and Gulf of St. Lawrence, Canada, was examined using: (1) questionnaires mailed to fishermen inquiring about bycatches in 2000 and 2001 (n=2,277 or 44% of the fishermen with valid licenses); and (2) using data from an at-sea observer programme and sentinel fishery programme in 2001 and 2002. The questionnaire survey had a low response rate (22%) and provided bycatch estimates of 2,215 (95% CI 1,151-3,662) and 2,394 (95% CI 1,440-3,348) porpoises in 2000 and 2001, respectively. The low number of hauls monitored by at-sea observers prevented the estimation of bycatch levels for several zones and the study area as a whole, and provided only imprecise estimates for all other zones. The results from questionnaires indicated a 24-63% reduction in harbour porpoise bycatches since the late 1980s, whereas the at-sea observer programme provided bycatch levels for 2001 and 2002 that were unreliable and underestimated, approaching one quarter of those documented in the late 1980s. Although both indices indicated a decrease in bycatches since the late 1980s, the magnitude of this change remains uncertain given the weaknesses associated with the two approaches. Considering the maximum population rate of increase (Rmax) for harbour porpoises as 4% and the lower and upper 95% confidence limits (1,440-3,348) of our most reliable estimate of bycatches (i.e. the 2001 questionnaire survey results), the harbour porpoise population in the Gulf of St. Lawrence would need to be at least 36,000-83,700 individuals for current incidental catches to be sustainable. If the rate of increase is less than maximal, e.g. 0.5Rmax or 2%, then 72,000-167,400 harbour porpoises would be needed to attain sustainability. Kingsley and Reeves (1998) estimated that an average 36,000 to 125,000 porpoises occupied the Gulf of St. Lawrence during the summers of 1995 and 1996. Although the trajectory of the population since it was last surveyed in 1996 is uncertain, these findings suggest that bycatch levels might remain a cause for concern for the harbour porpoise population in the Gulf of St. Lawrence. The results from the comparison between the sentinel fishery and the commercial fishery subjected and not subjected to at-sea observations suggest that fine-scale temporal and spatial changes in fishing activities may greatly affect harbour porpoise bycatch levels.

The ecology and conservation status of river dolphins (Inia sp.) distributed in the lowland rivers of Bolivia are poorly understood and only recently have basic studies been conducted to investigate their population size, taxonomic status, distribution, behaviour, environmental threats and ecology in this region. This paper examines the distribution and encounter rates of the bufeo (Inia sp.) in the middle reach of the Bolivian Amazon and was conducted in the Mamoré River and four of its tributaries during the low water season. Methods were employed which can be replicated during future surveys of Bolivian river dolphins and the results can be compared with those from surveys of Inia throughout its range. Sixty-two hours were spent surveying for dolphins, with 68% of the effort in Mamoré River and 32% in its tributaries. The Inia encounter rates reported here (1.6-5.8 dolphins km21) are the highest recorded anywhere in its broad geographic range; and indicate the importance of continuing and expanding surveys in this area. The mean group size was greatest in the Tijamuchi River (3.3±2.96) and smallest in the Yacuma River (1.8±0.75) and the maximum group size was 14. The high bufeo encounter rates in the central Bolivian Amazon can be taken as a reflection of the general environmental status of the region; however, a growing human population, associated with an increase in boat traffic and fishing activity, poses a future threat to bufeos and their aquatic habitats.
A note on the occurrence of sperm whales (Physeter macrocephalus) off Peru, 1995-2002
Authors: Garcia-Godos Ignacio
Published: March 2023

Thirty-eight sightings of sperm whales (Physeter macrocephalus) were recorded off Peru (3-18°S) during 21 surveys conducted aboard platforms of opportunity, 1995-2002, with a search effort of 33,407 nautical miles of observation. Two main areas of concentration were detected: northern Peru (19 sightings) and southern Peru (16 sightings). Almost 58% of sightings occurred during the same or consecutive days. Group size ranged 1-18 individuals, with a mean of 3.5 (SD=3.9). The modal group size was one, accounting for 36.8% of sightings. Groups of three or more individuals accounted for 39.5%. An important increase in sightings occurred between 2001 and 2002, accounting for 68% of the records and suggesting migration into Peruvian waters from other regions. Positive correlations between indices of relative abundance and the anomaly of sea surface temperature were found, although warm events such as El Niño increased the uncertainty in sighting rates, reducing correlation values. The positive relationship between indices of relative abundance and commercial catch per unit effort for the squid Dosidicus gigas suggests some degree of interaction, although the extent of the role of this squid in the diet of sperm whales in the area requires further study
Strandings, mortality and morbidity of Indo-Pacific humpback dolphins in Hong Kong, with emphasis on the role of organochlorine contaminants
Authors: Jefferson Thomas A. , Hung Samuel K. , Lam Paul K. S.
Published: March 2023

Factors related to mortality and disease in Indo-Pacific humpback dolphins (Sousa chinensis) from Hong Kong waters were investigated by detailed examination of dolphin specimens found stranded from 1995-2004. In total, 86 specimens were necropsied, but many of these were too badly decomposed to provide much information. Skin and blubber biopsies were also collected from six identified living individuals and concentrations of organochlorines (DDTs, PCBs and HCHs) were determined from blubber samples of stranded and biopsied dolphins. A large proportion of the strandings (53.2%) were young-of-the-year. The most commonly diagnosed causes of death were net entanglement and vessel collision. The pesticide DDT showed the highest concentrations and the ratio of DDT to its breakdown products (and other information) suggests that there may be a recent or nearby source of DDT into the dolphins’ ecosystem. Concentrations of both DDTs and PCBs showed a pattern of increasing with age in males. In females, they increased until sexual maturity, then decreased, and finally increased again in late life. This is consistent with a hypothesised transfer of pollutants from mother to offspring during gestation and lactation. Inter-laboratory differences and effects of decomposition of specimens are two potential biases that may significantly affect the quality of the present data. In order to resolve the potential problems associated with these issues, a long-term biopsy collection programme has recently been initiated.

An Evaluation of EMD Coding in Livingston County
Authors: Sugden Spencer , Kochalski Katelynn
Published: March 2023

This research evaluated the Emergency Medical Dispatch (EMD) code implementation in Livingston County, New York. The Livingston County Dispatch Office is an International Academics of Emergency Dispatch (IAED) certified agency that codes jobs for Emergency Medical Services (EMS) with EMD codes. Using data obtained from Livingston County EMS (LCEMS)’s emsCHARTS from 2015 to 2020, we evaluated the accuracy of EMD code implementation by both comparing the EMD code used to the impressions put on the patient’s chart and by comparing the resources sent to the patient with the resources that were needed to treat/transport the patient (disposition). In addition, we evaluated which EMD codes were undertriaged the most and which were overtriaged the most. In our sample, the EMD code matched the impressions on the patient’s chart about 47.30%. The appropriate resources were dispatched to patients roughly three quarters of the time. Undertriage and overtriage were found to be not independent of the EMD code. Four EMD codes were identified that were dispatched BLS but went ALS more often than others and it is our recommendation that, in EMS systems similar to Livingston County’s, these codes be dispatched ALS.

Published: March 2023

Pada perusahaan Organda komunikasi yang diterapkan sudah cukup baik, namun memiliki kekurangan. Berdasarkan hasil survei terhadap beberapa karyawan, mereka berpendapat bahwa komunikasi yang diterapkan belum maksimal, seperti adanya kepasifan dalam menyampaikan informasi dan dapat dilihat dari menurunnya faktor sikap dalam penilaian kinerja, meskipun kualitas dan kuantitas kinerja cenderung meningkat.

Penelitian ini bertujuan untuk menguji dan mengetahui lebih jelas bagaimana pengaruh komunikasi terhadap kinerja Organda dan sebagai penerapan pengetahuan, pandangan dan wawasan bagi penulis mengenai teori dan aplikasi dari pengaruh komunikasi dalam meningkatkan kinerja Organda.

Adapun teknik pengumpulan data dalam penelitian ini dilakukan dengan observasi yaitu suatu teknik pengumpulan data dimana responden tidak mengetahui sedang dijadikan sumber data atau penelitian, dengan wawancara, penelitian studi dokumentasi dan penyebaran kuesioner (angket) kepada 66 orang responden dengan 19 item pertanyaan melalui bantuan program Statitical Product Service Solution (SPSS) Versi 15.00 dengan teknik analisis Regresi Sederhana (Simple Regretion) dengan cara melakukan uji validitas dan reliabilitas.

Dari hasil uji coeffesien determinasi didapat angka Adjusted R Square sebesar 0,594 yang dalam hal ini berarti 59,4%. komunikasi dapat diproleh dan dijelaskan oleh Kinerja organisasi. Sedangkan sisanya (100% -  59,4% = 40,6%) dijelaskan oleh pengaruh faktor lain yang tidak dimasukkan dalam penelitian ini seperti gaya kepemimpinan, budaya perusahaan dengan persamaan regresinya adalah Y = 7,492 + 0,683 X. Konstanta  sebesar 7,492 menyatakan jika tidak ada variabel Komunikasi, maka Koefisien Variabel Kinerja Organisasi tetap  sebesar 7,492.

Berdasarkan analisis of varians (Anova) diketahui bahwa nilai angka F hitung sebesar 96,034 sedangkan Ftable 2,37 dengan tingkat signifikan  0,000. Oleh karena jauh dibawah 0,05 probabilitasnya maka model regresi layak dipakai untuk memprediksi kinerja organisasi sedangkan dari hasil pengujian hipotesis didapat nilai t hitung adalah 9,800 dibanding t tabel (dk = n – k ) 66 – 1 = 65 dengan taraf signifikan a = 0,05    (5%) diperoleh  t  tabel = 2,000 maka t hitung 9,800 > 2,000 t tabel, dengan berdasarkan hipotesis diatas maka Hi diterima, Ho ditolak artinya ada pengaruh yang signifikan Komunikasi terhadap Kinerja Organisasai. Hal ini menyatakan bahwa hipotesis yang penulis ajukan sebelumnya diterima.
Bank Specific as Moderator Between Intellectual Capital and The Performance of Malaysian Microfinance Institutions

This study aimed to investigate whether intellectual capital (IC) impacts the performance
of microfinance institutions (MFIs). This study also attempted to uncover the effect of microfinance institution specification (banks or non-banks) as a moderating variable in the association between intellectual capital and MFIs performance. There were 300 respondents, however, only 156 managers answered the structured questionnaires that were sent out using the purposive sample technique. The partial least square structural equation modeling (PLS-SEM) was used to analyze the research model in this study. The findings show that human capital and structural capital have a favorable impact on MFI performance. This influence, however, does not extend to the MFIs' customer capital and social capital. Furthermore, the research model can explain 59.9 percent of the significant variance in MFI performance. This study contributes to the theoretical expansion of the resource-based view (RBV) in forecasting the MFIs success. The framework suggested in this study can be used as a reference to assist MFIs management in selecting relevant intellectual capital aspects to improve Malaysian MFIs.

Kristen apologetikk som teologi, kommunikasjon og misjonalt perspektiv
Authors:   NLA Høgskolen, Dahle Lars
Published: March 2023

I denne korte refleksjonsartikkelen presenteres kristen apologetikk ut fra tre forskjellige men utfyllende perspektiver. Apologetikk kan nemlig med full rett beskrives både som et teoretisk teologisk fagfelt (science) og som en kommunikativ teologisk praksis (art). For det tredje kan apologetikk imidlertid også beskrives som et misjonalt perspektiv. Artikkelen har sitt utgangspunkt i utdanningsfaglig arbeid med pedagogiske og didaktiske spørsmål i tilknytning til studiet kommunikasjon og livssyn (KL) ved NLA Høgskolen Kristiansand.
Hvordan kan vi bygge bro over skellet mellem analytisk og kontinental teologi?
Authors:   Dansk Bibelinstitut / Fjellhaug Internasjonale Høgskole, Mørch Michael Agerbo
Published: March 2023

I denne artikel undersøges mulighederne for at bygge bro mellem de kontinentale og analytiske traditioner i systematisk teologi. Dette problem behandles av forfatteren i fire trin: “Først vil jeg forklare, hvordan jeg forstår problemstillingen, herunder hvad jeg forstår som årsagen til den kløft, jeg søger at bygge bro over. Det andet og tredje trin handler om at identificere mere præcist, hvad kontinental og analytisk teologi er. Hvad er de vigtigste kendetegn ved disse traditioner? Herefter vil jeg i det fjerde trin analysere konflikten nærmere under overskrifterne ‘tilsyneladende uoverensstemmelser’, ‘forskellige interesser’ og ‘mulig kompatibilitet mellem traditionerne’.” Forfatteren giver en række forslag til, hvordan der kan bygges bro mellem traditionerne, samtidig med at han kritisk forsøger at bestemme, hvad mæglingen forsøger at forene, samt hvad som ikke kan forenes uden at dispensere for ufravigelige indholdsbestemmelser i de forskellige traditioner.
