Authors: Alda Liana Maria , Bordean Despina-Maria , Alda Simion , Moigradean Diana , Danci Marcel
Published: October 2023

Algae are some of the oldest forms of life on earth, being consumed for centuries. There are numerous studies that highlight the health benefits of consuming seaweed, due to the high content of proteins, dietary fibers, vitamins, antioxidants, and the low-fat content. Nori seaweeds, which is used in the preparation of sushi rolls, stands out for its low caloric intake and high content of minerals, vitamins (vitamin B12 and vitamin C), as well as iodine. Only certain types of species of seaweed are used to make Nori: Porphyra tenera, Porphyra yezoensis, Porphyra umbilicalis and Pyropia tenera (a newer name for Porphyra tenera, due to a taxonomic reclassification). In this work, we analyzed the mineral profile of some varieties of Nori algae available on the Romanian market, obtained in China and Japan. To determine the mineral content, we used X-Ray Fluorescence Analyzer (XRF). The results are expressed in mg/kg dry weight. The Nori dried seaweed recorded the highest values of potassium and calcium and the Nori roasted seaweed the highest iron and zinc contents. Our experimental results recommend the consumption of Nori algae, in order to cover the daily requirement of minerals.

Published: October 2023

The article presents the creation of an experimental model of a hybrid vehicle intended to work both in conventional environments, in which the use of a diesel engine is permitted, and in environments with pollution restrictions (noxious emissions), in which an electric motor powered by batteries is used. At the level of the experimental model, the chassis of the drive train was made and tested, and the results were compared with those obtained by simulation with AMESim. The equipment in the NRMM (non-road mobile machinery) category have medium and high powers (of the order of tens or hundreds of kW) and, regardless of the primary energy source, they predominantly use hydrostatic drive for the work equipment. In the case of the presented hybrid vehicle, the work equipment is supplied with hydrostatic energy from a secondary pump. The machine can work in heavy environments with a lot of dust, moisture or rough terrain where the electric motors mounted in the wheel of the vehicle do not give very good results. Traction is achieved on all four wheels of the car using hydraulic wheel motors with radial pistons. This type of engine ensures a high torque at low speeds, necessary for the types of work performed.
The article presents the main subassemblies of this machine, the hydraulic drive scheme, the energy sources (thermal engine and LiFePO4 type battery group), as well as the machine's control system. The final goal of the authors is the development of a work equipment for underground constructions, in partnership with an established manufacturer from Romania.

Published: October 2023

Resilience is an essential psychological trait for rescuers, as their work involves responding to emergencies and disasters in challenging and often dangerous environments. In the case of rescuers, resilience enables them to remain calm and focused under pressure, cope with the physical and emotional demands of their job, and recover from the traumatic experiences they may encounter in the course of their work.
Rescuers often face a range of stressful and challenging situations, such as working in confined spaces, dealing with hazardous materials, and navigating complex rescue scenarios and may also be exposed to traumatic events. In these situations, resilience can help rescuers to maintain their composure, remain focused on their task, and make effective decisions.
Overall, the resilience of rescuers is a critical factor in their ability to perform their jobs safely and effectively, and to cope with the physical and emotional demands of their work. By developing resilience and receiving support as needed, rescuers can continue to provide lifesaving services in the challenging and often hazardous environment of a mine.
The current paper aims to underline the importance of resilience and to provide strategies to enhance it in the case of intervention and rescue personnel.

Published: October 2023

Disposal of waste generated by the industries remains one of the major challenges to preserve the environment. Indeed, the use of industrial waste and by-products in construction is an important advantage to conserve natural resources. For this reason, several studies have focused on the use of marble waste in construction as recycled aggregate or fine powder. The work aim is to investigate the physical properties and mechanical behavior of eco-friendly mortar made with marble powder. The experimental study consists in studying the effect of cement substitution by marble powder (0%, 5% 10% and 20% wt.) on the fluidity and mechanical properties (Flexural strength, compressive strength and mechanical behavior) of elaborated mortars. The results show that it is possible to manufacture an ecological mortar having the good mechanical characteristics with marble powder and with local materials with the same basic components as a normal mortar and thus obtaining the same characteristics as those known internationally. The content amount of the marble powder as an addition to the cement is satisfactory to produce an ecological mortar with good resistance and better cement economy.

Published: October 2023

Agricultural activity accounts for two-thirds of the total anthropogenic nitrogen oxide (N2O) emissions worldwide. Most of the N2O emissions from agricultural soils come from the use of inorganic fertilizers and/or manure. As agricultural activity intensifies worldwide, N2O emissions are currently increasing by 0.25% per year. In order to investigate the feedback of soil N2O emissions with changes in environmental conditions, an improved understanding based on the wider use of isotopic tracer methods is needed. The aim of this study is to find out the formation of N2O in agricultural soils, as well as to find out other significant influencing factors that influence the formation of isotopes. To perform the experiment in laboratory conditions, 16 mixed soil samples from different experimental plots were collected. The fields have different types of management, there are both conventional and organic fields. For each experimental plot, two soil samples were created with different moisture regimes, one container with normal moisture regime and the other with over moistened conditions, such soil regimes were chosen to create both moist aerobic and moist anaerobic conditions. Soil samples were also measured for ph. N2O isotope measurements were performed using a Picarro G5131-i instrument. Measurement data were collected, processed and further analyzed. The formation of N2O isotopes in the soil is influenced by several factors, both soil moisture and physical properties of the soil, soil ph. level and microbiological activity in the soil.

Waste Water Treatment Plant (WWTP) belong to the so-called �critical infrastructure�, which are so essential that their continued operation is required to ensure the security of a people. Energy is the most important operating utilities of WWTP. The specific electric energy consumption of WWTP depending on many factors including the inflow quality, WWTP�s scale, the technology used and climate. High energy consumption indirectly produces ecological damage, accelerates the energy crisis, and increases carbon emissions. The article will present data on analysis electricity consumption and carbon footprint at a small wastewater treatment plant in southern Poland. Electricity consumption of the analyzed wastewater treatment plants in 2019-2021 ranged from 221 714 to 248 824 kWh/year, with an average value of electricity consumption rate per m3 of wastewater: 1.15 kWh/m3. Rising amount of pollutants conducted into the treatment plant results in an increased energy demand. However, this correlation does not take a linear character.
COMPERATIVE ASSESSMENT OF THROUGHFALL COMPOSITION IN BEECH ECOSYSTEMS IN WESTERN BULGARIA
Authors: Damyanova Sonya
Published: October 2023

An assessment of processes in forest stands requires the monitoring of many parameters. The annual dynamics and composition of precipitation show the impact of atmospheric depositions on ecosystems. Throughfall depositions play a significant role not only in the dynamics of canopy processes but also influence soil conditions through the interception processes and element changes in canopies. The study was carried out in two permanent sample plots located at different altitudes in the Western Stara Planina in Bulgaria. The Petrohan site is a part of the Long-Term Ecological Research Network and is located at 1480 m above sea level. Another site, Barzia, is located 634 m above sea level. The obtained results show a higher concentration of base ions (Ca2+, Mg2+, Na+, K+) and a lower concentration of acidic ions (NH4 -, NO3 -, SO4 2-) at higher altitude. The concentration of toxic lead and cadmium ions were higher at highland ecosystem, which is affected more by anthropogenic influence on a certain extent. The amount of throughfall precipitation was greater in a higher mountainous site than in a lowland. The corresponding levels of most of deposited elements were higher at the Petrohan site than at the Barzia site. pH of throughfall precipitations indicates no risk of acidification of both stand and soils.
ENVIRONMENTAL ASSESSMENT OF COAL MINING PRACTICES IN SVALBARD: INSIGHTS FROM SOIL, VEGETATION, AND COAL ELEMENTAL ANALYSIS
Authors: Abramova Anna
Published: October 2023

This study quantifies the elemental composition of soil, vegetation, and the level of trace elements in coals to identify the impacts associated with coal mining practices in the Longyearbyen and Barentsburg settlements, the Svalbard archipelago. The analysis is based on a data set that includes 26 chemical elements measured in 74 soil, 29 vegetation, and 4 coal samples provided by a catena-based survey strategy. The concentrations of lead (Pb), nickel (Ni), copper (Cu), zinc (Zn), chromium (Cr), and vanadium (V) in the soils did not exceed the European regulatory standards (the Finnish Standard and the Norwegian Soil Quality Standard), while arsenic (As) and cadmium (Cd) overstepped their threshold values in some soils. The Geoaccumulation Index (Igeo) values showed that soils were enriched in titanium (Ti), strontium (Sr), boron (B), and zirconium (Zr). The elemental screening of the exposed coals, soils, and vegetation revealed high concentrations of these four elements as well. The examination of geospatial patterns shows that the concentrations of Ti, Sr, Zr, and B in the soils are distributed evenly along the most of the sampling transects (catenas). While the distribution of elements in the soils between the transects (catenas) varies considerably, the highest concentrations for Ti, Sr, B, and Zr are observed near the currently operating coal mining and transportation facilities.

Published: October 2023

Addressing environmental issues is related to the scientific, economic, social, and political issues of a particular country. Human impact on nature is increasingly strong to equal to the action of natural factors, resulting in an imbalance of forces between society and nature. Day by day, pollutants accumulate in some or other environmental object, some of which do not take part in the natural cycle and accumulate in the biosphere, causing adverse ecological consequences. Mining industry plays a special role in the formation of technogenic relief. The technogenic impact, unlike other anthropogenic factors, leads to the pollution of large areas of terrain and water resources and their complete transformation. A typical example of this is the area of development of the Chiatura manganese deposit, where the relief is subject to radical changes with complete destruction of the soil and vegetation cover. Manganese is mainly mined by open-pit method, while the Kvirila River is constantly polluted during ore dressing. The content of manganese ore in the River is 10 to 12%. The waste rock accumulated following ore mining have formed hills, short ridges and embankments with the relative heights of over 10-30 m. However, sometimes, the relative heights of the hills and ridges formed by the accumulation of waste rocks on landfills exceeds 100 m. Their erosive processes pose additional risks of environmental pollution. The dispersion of chemical elements during the production process is often uncontrolled. As a result, technogenic aerosols may be released into the atmosphere, and soils, open water bodies, and rivers may be polluted by industrial wastes. The field and laboratory studies have established that, along with manganese, other heavy metals such as copper, nickel, zinc, and others pollute the environment.

Published: October 2023

One of the areas in Romania where the environment felt from human activities is Jiu Valley (Petrosani Depression), an area where the main activity was mining. This fact led to pollution of the area, pollution that affects both health of population and tourism, which is considered as a viable economic alternative.
Investigation of environmental components, identification and analysis of impact sources on air and surface waters are the objective of this paper, which is a first step of a larger research, that will lead to establishing the pollution degree of the area under study.
The paper presents pollution sources, methods of analyzing environmental indicators, as well as the impact of economic activities on the environment.
The main conclusion of the scientific approach is that, in addition to mining activities that had and still have a negative impact on the environment, other economic activities carried out in the area, including household activities, also leave a negative impact on the environment. Which of these (quantitatively speaking) leave a larger or smaller footprint will be the subject of a future paper, that will quantify all air and water quality indicators.

Published: October 2023

Currently, the food industry accounts for the largest amount of waste, a third of which is waste from the processing of fruits into natural fruit juices, the consumption of which has recently increased significantly due to health problems among the population. The transition to a healthier and more natural lifestyle involves reducing the consumption of soft drinks, which can contain high concentrations of sugars, artificial colors, preservatives, and increasing the production of natural juices.
Studies were carried out on citrus fruits: mandarin, lemon, orange and pomelo. The possibility of valorization of citrus fruit juice production waste: peel and juice bags to obtain high-quality dietary fiber-pectin was studied. The process of pectin hydrodistillation has been studied: the influence of the collection time and fruit morphology on the pectin yield, the time of pectin extraction and the type of extractant have been determined, the kinetics of the extraction process and its dependence on the temperature and concentration of the extractant have been studied, for a more complete isolation of the pectin sol, the need for preliminary concentration of its extracts by membrane methods has been shown. Based on the study of pectin quality parameters, such as the content of galacturonic acid and the degree of esterification, the optimal parameters of the pectin extraction process were formulated.

Published: October 2023

Geopark networks are expanding globally, with the main purpose to protect geoheritage. In many places of the world geopark sites are associated with local cultural heritage and indigenous people. These links sometimes are synergistic, whereby geoparks serve as important protected areas that allow for preservation of important cultural objects and even support livelihoods of indigenous people. However, in some cases geopark development is perceived negatively by local communities and might have potentially damaging effects on local culture. Geopark networks are likely to expand and may have important contribution to local culture preservation. However, in order to successfully implement new geoparks it is important to understand factors contributing to their positive effects on local cultures and the ways to address potential conflict areas. In this article we critically evaluate these factors, considering both synergies and conflicts, and propose recommendations for new geopark siting and management that could help to maximise their contribution to cultural conservation and development.

Authors: Grecu Andreea
Published: October 2023

Our current IT innovations will alter the way government agencies operate. The relationship between public administration education and new forms of governance, such as e-government, is thus something to consider. Public administration education must be updated to reflect the structure of future governments. The paper discusses a number of key topics that are connected to the topic. Evolving aspects start to appear in public management in this century of information and information technology. Also, numerous books analyse the needed change in public administration. And finally, the curricula used nowadays for public administration education will have take into account these new evolutions. And third, these new developments will need to be accounted for in the curricula utilized today for public administration education. To ensure the connection between government and public administration education, the current curriculum must undergo at least a few major adjustments as a result of the evolving aspects of public management in the information society. Current curriculum urgently need to be updated to meet the needs of emerging concerns, and decision-makers need to learn more about government in order to make the necessary changes to the way the government operates. Medical crisis managed to the best of the abilities for an issue unprecedented as magnitude and economic and social impact - economic and administrative system has been saved by digital tools and platforms. A non representative sample was used in order to analyse the behaviour of more than 55 public institutions. The aim was to identify common patterns in approaching challences induced by the citizens expectations in relation with public system. Additionally, there is need for improvement in how public decision-makers view and relate to IT tools. As long as professionals and academics analyze and pinpoint a route for these developing issues in the public administration education, these goals can be achieved.

Today's time is characterized by a high degree of globalization and trade borders are both physically and commercially open, and a competitive organization must also take into account factors that were less important in the past. Any company that operates in a market environment is influenced by this environment and to some extent helps to cocreate this environment. The current time in connection with the COVID-19 pandemic and the war conflict in Ukraine represents a difficult test for all business entities. In these uncertain times, it is important to adapt and respond to change. In addition, during the recent period when the world was hit by the above-mentioned negative influences and which are still ongoing, it is important to react essentially on a day-to-day basis and to have ready action plans. Currently, almost all companies see a huge advantage in strategic management and planning, which is why they follow them and create various strategic plans, strategic analyzes of the macro-environment, or micro-environment. For this reason it is correct the strategic analysis carried out is extremely important for any business. A relatively new field of science, namely behavioral management, which is dealt with by the authors in this paper, also has an indisputable influence on the strategic decision-making of managers.

Published: October 2023

Mycotoxins are agents with different and complex chemical structures, with toxic effects for humans and animals. They can be present in feed and food, although in very small quantities, mycotoxins have a negative effect on the health of animals and people. Ochratoxins are mycotoxins intensively studied in recent years due to their toxicity on the animal and human body; these toxins show nephrotoxic, immunotoxic and myelotoxic, neurotoxic and carcinogenic effects. Thirty male rats of the Sprague- Dawley breed were divided into 3 groups who received through feed doses of of ochratoxin A (OTA): 0.5 mg OTA/kg BW, 1 mg OTA/kg BW and non OTA (control group). The blood samples collected on the anticoagulant were subjected to the analysis of the main components: hemoleucogram and biochemical parameters. The variations of the determined biochemical parameters (alanine aminotransferase, aspartat aminotransferase, serum creatinin, serum urea and blood urea nitrogen) indicate changes in the kidney and liver function in the animals from the experimental groups compared to the control group. The parameters of the hemoleucogram count also register variations depending on the administered dose of OTA.

Published: October 2023

Suppression of fungal phytopathogens is one of the serious challenges agriculture and forestry since they cause significant biomass and yield losses. One of the alternative methods of suppression phytopathogens is the use of biosurfactants, which are amphiphilic substances produced by many microbes. Bacteria of Pseudomonas genus are known to produce biosurfactants of the rhamnolipid class. These surfactants can possess antimicrobial and fungicidal properties.
In this work, we studied the effect of various concentrations of rhamnolipid (100, 500, 1000 mg/l), produced by Pseudomonas aeruginosa PAO1 strain on the growth of fungal pathogens Fusarium oxysporum and Alternaria spp on tomato leaves that were a) separated from the plants and b) not separated from the plants.
On infected separated leaves without biosurfactant treatment, the area covered by Alternaria spp and F. oxysporum was 28% and 8%, respectively. The growth of Alternaria spp was fully inhibited when the leaf spayed with 1000 mg/l rhamnolipid before artificial infection, and of F. oxysporum � with 100 mg/l rhamnolipid. On unseparated biosurfactants-untreated leaves that remained growing on the tomato plants after artificial infection with Alternaria spp and F. oxysporum was 4.7 and 4.2 scores, respectively. Infection of the leaves did not lead to infection of the whole plants since infected leaves were defoliated. Interestingly, biosurfactants treatment led to growth stimulation of tomato plants at a concentration of 1000 mg/l.
It can be concluded that rhamnolipid produced by P. aeruginosa PAO1 is a promising biocontrol agent.

Published: October 2023

In a view of the sustainable development principles, the development of advanced lowcarbon building materials represents one of the most important issues in the construction industry. To follow the current trends in research and development of building materials, special attention is paid to the reuse of all kinds of waste and industrial byproducts. One of the serious problems of today�s society is the huge production of sewage sludge from waste water treatment and its disposal. As one of the promising ways of sewage sludge disposal is incineration, there is a need to study biomass ash, its environmental hazards and further use in industrial applications. In this paper, the heavy metal contamination of biomass ash is analysed together with its chemical and phase composition, reactivity, microstructure and morphology. As the biomass ash was found to be pozzolana active, it was admixed to cement mortar, and the structural and mechanical parameters of this material were tested. The use of biomass had no negative effect on the properties of the cement mortar. Since the content of heavy metals in the biomass ash was safely below the valid limits, and the water-soluble salts were immobilised in the blended cement matrix, the biomass ash studied was classified among the alternative low-carbon pozzolans applicable in the development of eco- and energy-efficient construction products.

Authors: Pavlikova Milena , Pavlik Zbysek
Published: October 2023

This paper focuses on the experimental testing of hydrated lime-, natural hydraulic lime-, and lime-cement-based mortars with improved salt accumulation capacity. Moreover, the effect of varying content of non-hydrophobised expanded perlite (EP) in the mortars on their durability was investigated. The substation of silica sand by expanded perlite was 25%, 50%, 75% and 100% by volume. A modified method based on the adsorption of free salt ions from solution was used to measure the chloride binding isotherms. The salt concentration was analyzed using an apparatus working on liquid chromatography technique. The data acquired were compared with reference mortars with natural silica sand as an only aggregate. The use of expanded perlite significantly increased the chloride binding capacity of the tested mortars, while no deterioration was observed for samples contaminated with salts. The results obtained thus validated the applicability of most of the mortars tested for the repair of masonry structures including the restoration of renders and plasters. When repairing historic masonry, compatibility issues must be considered, in this case with respect to the type of binder used.
TRANSPORT MANAGEMENT IN URBAN AREAS
Authors: Kubis Zdenek , Plocova Kristyna
Published: October 2023

Effective transportation planning must take into account urban factors and public space in order to achieve sustainable and efficient solutions to transportation problems in urban areas. Public space includes not only parks, squares, and markets, but also sidewalks and roads. Properly managed transportation in public space can help minimize traffic congestion, ensure efficient and safe movement of vehicles, pedestrians, and cyclists, and overall improve its quality.
The specific example which is frequently used in urban areas is adaptive traffic control system. It is able to automatically modify the length and frequency of green signals for individual directions depending on traffic situation. Adaptive traffic control uses sensors and camera systems that can detect traffic flow. Based on this data, they can modify traffic signal timing in real-time.
It is important to consider urban factors and public area when we are using adaptive traffic control, For example, traffic signals control system may prioritize the traffic flow of pedestrians, cyclists or public transport. This prioritization can contribute to a more balanced use of the public area, thereby improving its overall quality. They can also help improve smoother traffic flow, reducing traffic congestion and its impact on air quality and noise pollution in urban areas.

Objectives: This study aimed to evaluate the awareness of oral cancer and oral premalignant lesions in dentistry student at three different faculties. Materials and Methods: The question-based questionnaire study included 382 fourth- and fifth-year students (n=382; 239 females, 143 males) from three different dentistry faculties in Türkiye. A cross-sectional questionnaire consisting of 43 questions about oral premalignant lesions and oral cancer was administered to fourth- and fifth-year students to assess awareness of knowledge, attitudes, and practical approaches between May 2023 and June 2023. Results: A statistically significant difference was observed between male and female fourth-year students (p=0.024). The mean values of male students were higher than female students. The highest values in terms of knowledge in the fourth and fifth years were observed in the Uşak University. In the fifth-year students, the highest values in terms of attitude and practice were observed in the students of Uşak University. Fifth-year students of Uşak University showed higher values in terms of knowledge, attitude, and practice than fourth-year students. In terms of attitude, fifth-year students of Tokat University showed higher values than fourth-year students. In total, fifth-year students showed higher values in terms of knowledge and attitude than fourth-year students. Tokat University showed higher awareness of oral premalignant lesions than the other universities. Conclusion: Early diagnosis of oral cancer and oral premalignant lesions are among the important responsibilities of dentists. Increasing the awareness of dentists in this area can contribute to the solution of a prominent public health problem.

Objectives: In this study, demographic data, foreign body characteristics, and treatment approaches of pediatric patients treated for foreign bodies in the otorhinolaryngology clinic were discussed. Patients and Methods: Demographic data, location, type, treatment method, and complications of 110 patients (54 male, 56 female; mean age 4.4±2.9 years; range, 1.5 to 16 years) who were treated for foreign bodies in the ear, nose, and throat between January 2022 and March 2023 were evaluated retrospectively. Results: It was observed that the mean age of children with a foreign body in the ear was significantly higher than the mean age of children with a foreign body in the nose (p<0.001). Of the foreign bodies, 57 (51.8%) were detected in the nose, 47 (42.7%) in the ear, and six (5.5%) in the throat. Of the foreign bodies, 39 (35.5%) were organic, 71 (64.5%) were inorganic, and the most observed foreign body was beads (n=18, 16.4%). The foreign body was removed under general anesthesia in five (4.5%) of the patients. Conclusion: Foreign bodies are one of the most common otolaryngological emergencies in the pediatric age group. Foreign bodies with delayed diagnosis and treatment may cause complications. Therefore, it is important that foreign bodies are removed by otolaryngologists using appropriate instruments and techniques.

Objectives: The study aimed to evaluate the Turkish validity and reliability of the benign paroxysmal positional vertigo (BPPV) diagnostic scale. Patients and Methods: One hundred seventeen patients (67 females, 50 males; mean age: 49.3±12.3 years; range 18 to 74 years) over the age of 18 who were diagnosed or suspected of BPPV, Meniere's disease, vestibular neuritis, or other peripheral vestibular disease were included. Participants filled out the BPPV diagnostic scale. The affected canal and the ear side were determined by performing positional maneuvers to confirm the diagnosis of BPPV. The final version of the scale was created by performing language and content validity, construct validity, reliability, and test-retest analyses of the BPPV diagnostic scale in the given order. Results: Of the 117 patients, 70 were diagnosed with BPPV, 26 with Meniere’s disease, 16 with vestibular neuritis, and five participants with other peripheral vestibular disease. Kendal W for content validity was 0.060 (p=0.700>0.05), and expert opinions showed good agreement. The factor load of the BPPV diagnostic scale was found within the normal range (0.364 to 0.807). Goodness of fit index values were obtained above 0.90. According to this result, the model fit well. The internal consistency Cronbach's alpha (a) coefficient of the scale was 0.716. This value showed that the scale had good reliability. According to the results of the scale, a statistically significant difference was found between the responses of the BPPV group and the other diagnostic groups (p<0.05). Conclusion: The Turkish version of the BPPV diagnostic scale was found to be valid and reliable. This scale is useful in detecting BPPV and establishing the differential diagnosis. The use of the scale is thought to be beneficial in patients with suspected BPPV but who have difficulties in diagnosis and to support objective tests.

Objectives: The newborn hearing screening test results with the automated auditory brainstem responses (AABR) test in our hospital was discussed in the light of current literature. Patients and Methods: The data of 379 newborn babies (202 boys, 177 girls) who underwent AABR test as a newborn hearing screening test between September 1, 2020, and September 1, 2021, were retrospectively scanned through hospital records, and the results were analyzed. Results: Fifty babies could not pass the first test. One baby did not come to the second test, and the family could not be reached. Three out of 49 babies failed the second test and were referred to the reference center. Although 28 babies passed the first or second test, they were referred to the reference center since they had risk factors. Conclusion: Hearing loss of newborn babies should be diagnosed in the first three months, necessary intervention should be made within six months, and both fitting aids and training should be started. Increasing the number of reference centers and the development of follow-up systems that provide feedback from referred patients will make screening programs more successful.

Abstrak
Dalam beberapa tahun terakhir, banjir telah menyebabkan gangguan pada sistem pengelolaan jalan dengan meningkatkan biaya rehabilitasi secara signifikan. Pada penelitian ini dilakukan analisis pengaruh banjir, lalu lintas dan riwayat penanganan terhadap deteriorasi kondisi perkerasan jalan dimasa akan datang. Analisis dilakukan pada semua ruas jalan nasional di provinsi Bengkulu. Berdasarkan MPT yang dihasilkan, kondisi kategori lalu lintas mempengaruhi tingkat penurunan maupun kenaikan kondisi perkerasan dimana lalu lintas tinggi memiliki tingkat penurunan kondisi perkerasan lebih tinggi daripada lalu lintas sedang maupun lalu lintas rendah. Kondisi antara segmen banjir dan tidak banjir juga berbeda dalam perubahan kondisi perkerasan dimana segmen banjir tingkat penurunan kondisi perkerasan lebih cepat dari segmen tidak banjir. Pada analisis perubahan kondisi perkerasan di masa akan datang, perbandingan jumlah keputusan penanganan yang diberikan pada Markov Chain probabilitas tertinggi dibandingkan dengan IRMS V.3 menunjukan hasil yang berbeda, dimana pada Markov Chain penurunan kondisi perkerasan baik IRI maupun PCI lebih cepat sehingga lebih sering dilakukan penanganan rehabilitasi daripada menggunakan IRMS V.3 yang penurunan kondisi jalan cendrung lebih lambat.

Abstract
In recent years, floods have disrupted the road management system by significantly increasing rehabilitation costs. In this study, an analysis of the flooding’s effect, traffic and maintenance history on the deterioration of pavement conditions in the future was carried out. The analysis was carried out on all national road sections in Bengkulu province. Based on the resulting MPT, traffic category conditions affect the level of decrease or increase in pavement conditions where high traffic has a higher rate of decline in pavement conditions than medium traffic and low traffic. The conditions between the flooded and non-flooded segments are also different in terms of changes in pavement conditions where the flooded segment has a faster rate of decline than the non-flooded segment. In the analysis of future deterioration of pavement conditions, a comparison of the number of treatment decisions given to Markov Chain has the highest probability compared to IRMS V.3 showing different results, where on Markov Chain the deterioration of pavement conditions, both IRI and PCI, is faster so that rehabilitation is carried out more frequently. rather than using IRMS V.3 which tends to decrease road conditions more slowly.
