Forty-five years of man-machine systems: prospects for advanced robotics
Authors: Sheridan Thomas
Published: December 2020

The origins of development of intellectual discipline for interfacing human and machine are reviewed in terms of three fifteen-year phases from 1940 to 1985. The first phase concentrated on empirical studies and design of the physical human-machine interface, i.e., displays and controls. The second phase focused on the transformation of systems engineering models to characterize the entire closed loop communication, decision and control system containing the human operator. The third and most recent phase emphasized the application of computers to aiding and implementing operator decision. The currently available knowledge combined with the technologies of advanced computers, sensors, robot effectors and the techniques of artificial intelligence and control is now producing a new phase of telerobotics which portends fundamental change in the way people work. The emergence of telerobotics has newly accentuated four classical dilemmas: (1) determinism vs. free will; (2) reliability vs. creativity; (3) utilization of new technology vs. prevention of worker alienation; and (4) objectivity vs. advocacy. The relevance of each to telerobotics and human work is discussed. Society is now at the point of having to decide what mix of human and machine is best to produce desired goods and services and to satisfy the aspirations of workers and organizations.

Authors: Butera Federico
Published: December 2020

At the end of the '90s, digital technologies took command changing global value chains, business models, services, organisational functioning, work. Business Process Reengineering, Lean Production, CSCW (Computer Supported Cooperative Work) became very popular approaches among managers overshadowing the STS (Sociotechnical Approach). In this chapter, a reconsideration of sociotechnical approach is proposed in line with the digital revolution and the new needs for rapid and radical changes. The positive aspect of those approaches are partly incorporated in the proposal of a Sociotechnical Approach 2.0: going back to the basic as process centred organization, quality of working life, process of design and change.

A classification of regions of Ukraine by the level of formation of social tensions together with determination of preventive measures aimed at preventing the creation of crisis situations are carried out. It is proved that the socio-economic situation typical for Ukraine has deteriorated significantly. This is evidenced by the decline of a large number of international indicators that characterize the stability of the country’s development. The suggested in the article methodological approach to the classification of regions by the level of formation of social tensions includes two main stages: substantiation of the system of socio-economic indicators that characterize the level of social tension; selection and substantiation of models of classification of regions. The carried out analysis of the values of socio-economic indicators of each cluster allowed to allocate the following classes of regions by the level of formation of social tension: 1st class – increased level of formation of social tensions; 2nd class – low level of formation of social tensions; 3rd class – high level of formation of social tensions. Of particular importance for the research is the 3rd class, i.e., the class with a high level of formation of social tensions, which leads to a crisis. The regions of this class should have serious government support in the social sphere. The results of the research showed that the number of regions classified with high level of social tensions is constantly growing and, unfortunately, the number of regions where the social sphere is more developed is decreasing. It should be noted that this situation is extremely dangerous, because it can lead not only to social, but also economic and political crises. The carried out analysis of the status of region of each of the received classes provides the possibility to prevent aggravation of crises in the social sphere and determine the list of preventive measures that can lead to a decrease in losses both in terms of individual classes and in the State as a whole.
Small and Medium Business amidst Economic Turbulence: Ukraine’s Experience
Authors:   Kyiv National Economic University named after V. Hetman, Rudyk N. V.
Published: December 2020

In Ukraine, the importance of small business for the economy and the need to stimulate it are being realized at the level of both the scientific community and public administration. The situation with the pandemic has complicated the conditions of functioning of small and medium-sized busines entities (hereinafter SMEs), but at the same time has justified the need to support it not only in the situation of collapse, but also as a matter of socio-economic stabilization and the prospect of reducing the unemployment rate. The status and conditions of SME functioning, its importance in various spheres of economic activity and in the labor market are researched. The emphasis is on modern trends in the functioning of SMEs, financial relations between the State and SME entities. A comparison of classification characteristics of SMEs was conducted in accordance with the Tax and Commercial Codes of Ukraine. The conditions of operation of small and medium-sized businesses on a simplified taxation system are compared. The latest legislative changes related to the stabilization policy of the State are taken into account. To identify the main trends of small business development, an analysis of the dynamics of the quantity, composition and structure of business in terms of its size, as well as the dynamics of the number of small enterprises and individual entrepreneurs by the largest groups in accordance with the classification of domestic economic activity in the country was carried out. The significance of SMEs in the employment structure is defined in the plane of enterprises and in terms of their size; the need to stimulate entrepreneurship in conditions of global instability is proved. A chronological analysis of the introduction of fiscal instruments for supporting the State in an emergency situation was carried out. In view of international experience, alternative quarantine preferences are considered as possible measures of the State support.
Estimating the Payback Period of an Investment Project in the Framework of a Fuzzy Set Statement of the Problem
Authors:   Kyiv National Economic University named after V. Hetman, Kotsyuba O. S.
Published: December 2020

The article is concerned with the problem of fuzzy-set-based evaluation of the payback period of real investment projects. Initially, the most general features of the approach, which is implemented to find a discounted payback period for an investment project in the form of a fuzzy value (number), were highlighted. After that, the approach to modeling the latter with the help of payback function was thoroughly considered. It is identified that, along with the obvious advantages of this instrument, its significant disadvantage, in terms of the original version, is that the scope of the payback function is limited to the investment projects, for which, after a minimum period of time, when there may be a payback scenario among other scenarios, the sequence of fuzzy estimates of the indicator of accumulated discounted cash flow is non-decreasing. The publication formulates a generalized version of the payback function of the investment project, free from this disadvantage. Using conditional data, the proposed modification was tested, which demonstrated its viability. Particular attention is paid to the formulation and approbation of the indicators that can be obtained on the basis of the payback function and which reflect certain, significant in terms of analytical needs aspects of the payback of the investment project in time.

Published: December 2020

In recent years, Ukraine experienced inadequate efficiency in forming strategic goals for the development of animal husbandry industries, which comprise the potential not only of agriculture, but also of the country as a whole, so research and scientific substantiation in this sphere is relevant. Particularly, the relevance of the study lies in the need to analyze the level of animal husbandry potential in terms of the number of animals and selling for slaughter in all categories. The article is aimed at studying the regional development of Ukraine according to the key indicators of animal husbandry, further identifying characteristic regional features and developing recommendations on development prospects. To research the impact of these factors on the development of animal husbandry, regions of Ukraine were classified using the methods of cluster analysis. This approach allows to build up scientifically grounded classifications, to determine internal links between individual objects of the studied population in the conditions of constant increase and complication of the statistic data flows. Two cluster analysis methods have been applied: building up a dendrogram and the k-means method. The carried out analysis defined three groups of regions characterized by similar features, where the regions belonging to the third cluster have the highest level of animal husbandry development, the second cluster has an average level of development, and the first cluster has the lowest level of animal husbandry development among all regions. Cluster analysis allowed to identify problematic situations and set out ways to solve them. Cluster approach allows to classify regions of Ukraine according to the aforementioned indicators, as well as develop differentiated strategies for improving the strategy of animal husbandry development at regional levels, to compound comprehensive ratings of animal husbandry development. Disparities in the levels of development of regions and individual components have a negative impact on the development of the State in general and should be researched to determine the government and regional policy, which would account the features indicated.

Authors:   Institute of Regional Research named after M. I. Dolishniy of the NAS of Ukraine, Maksymenko A. O.
Published: December 2020

The article analyzes the information content of the websites of amalgamated hromadas (AHs). On the example of AHs of Lviv region, a content analysis of the information on websites was carried out. Of the 41 formed during 2015-2019 amalgamated hromadas of Lviv region, 38 hromadas have created their official website. Mostly, the AHs’ websites cover: information about the activities of the management apparatus; information about the governance apparatus and the deputy composition of the AH council; budget and use of budget funds; participation of citizens in governance; regulatory activity/policy; strategic documents; passport of AH; detailed description of infrastructure, labor, agricultural, natural, tourism resources, enterprises operating on the territory of AH; there is a tab with information about ASC; investment passport and the land plots, which are intended for the implementation of investment projects, as well as information about the activities of various departments and communal utilities. It is noted that during the coverage of information on official websites, executive authorities should be guided by the Resolution of the Cabinet of Ministers of Ukraine «On the procedure for publishing information on the activities of executive authorities on the Internet», as well as Art. 15 of the Law of Ukraine «On Access to Public Information». It is determined that the most common is information about the composition and activities of the AH governance apparatus, information about the deputy composition, budget and use of budget funds, regulatory activities. The index of the amount of information covered is proposed and computed. It is concluded that AHs with general fund income (without transfers) per capita of more than 3000 UAH have more informatively filled websites. However, the type of hromada (urban or rural) does not influence the amount of information covered on the website. In general, the carried out analysis showed the lack of asymmetry in the disclosure and dissemination of information through the official websites of AHs of the Lviv region.

Published: December 2020

The article is aimed at researching the key problem of information and analytical provision of enterprise in the context of digitalization of the economy. The publication indicates the growth of the role of information in the implementation of management activities by an economic entity and its general role in the operation of the modern enterprise. Approaches to interpretation of the concepts of «information» and «information provision» are examined. It is defined that today the main problem of information-analytical provision of economic activity is the leakage of confidential information as one of the forms of materialization of threats to the information security of enterprise, which consists in violation of confidentiality, integrity and availability of information. It is further defined that the leakage of information at the enterprise is usually caused by the following actions: unauthorized access to confidential information; disclosure of confidential information (including the unintentional disclosure); leakage of information via the imperfect technical channels. The channels of possible information leakage are considered. In addition, the analysis of statistical data on information leakage in the global dimension was carried out. According to the researches, in 2019, among the total volume of information leakage, 49.7% of the volume is accounted for by external actors and 50.3% by internal offenders. In general, in the system of information and communication provision, special attention of the management of enterprise should be directly paid to internal communications, since more than 90% of the information comes in from employees. It should be noted that the reasons for the leakage of the enterprise’s information due to the fault of internal actors may be: unintentional actions on the part of the enterprise’s employees related to errors in the processing, storage or transmission of confidential data; the caused by certain reasons actions of employees who have access to confidential information. This may include the actions of employees who use the enterprise’s data for fraud purposes, as well as the actions of former employees who, motivated by their desire for retaliation for dismissal, «contribute» to the leakage of confidential information, passing it on to competitors or using it for their own mercenary purposes.

Published: December 2020

The publication is aimed at developing theoretical bases for research of the causes and consequences of global financial crises, as well as systematizing the typology of global financial crises to determine effective and efficient measures to influence their course and reduce losses from their consequences. Scientists-economists of different scientific schools provide unequal explanations, definitions and substantiations of the essence and causes of the development of global financial crises. In all cases, global financial crises cover financial markets, money turnover and credit, international finance; they manifest themselves through the rapid growth of interests, debts, reduction of loans, large-scale downfall in the securities exchange rate, massive losses in the market of derivatives, uncontrolled decline in exchange rates, etc. The introduction of effective and efficient measures to prevent global financial crises in early stages of their development can significantly affect their course and reduce losses from their actions and consequences. A typology of global financial crises is proposed, which takes into account the connections of their causes and consequences on the following grounds: the coverage of the monetary and financial system, the level of international economic relations, and perturbing factors. The latter cause global financial crises by implementing the cause-and-effect economic mechanisms. This results in the occurrence of contradictions between economic needs and a monetary and financial system.

Published: December 2020

The search for answers to modern challenges to both the global and the national economy is reflected in the focus of scientific and applied researches, their object and subject analysis. Such a search requires studying of qualitative changes in the processes of globalization and their combination with the origin in different countries of the trend of deglobalization. This trend is strengthened by the political influence of the countries with the use of policy of economic and technological protectionism, sophisticated rules of the game and instruments for gaining market advantages in both high-tech and financial markets. The present scientific research is aimed at analyzing the reasons for activating the structural policy of deglobalization, building up a related contentual model. The main reasons for accumulation of corporate debts by giants of global business are defined and their dual role in the development of both industrial and financial markets is reflected, the interaction between which is intensifying in the digital economy and with the emergence of new sources of crisis. The characterization of the gaps between the volume of exports and imports, the coefficient of coverage by exports of imports, the value of which depends on positive structural changes based on the processes of deglobalization and innovative activity of high-tech markets, are provided. Dynamic trends were built up to reflect the interdependence of volumes of foreign direct investments and the level of openness of the Ukrainian economy. The relationships of fragmentation factors of industrial and financial markets under the influence of the growing role of high-tech companies in the implementation of the policy of economic protectionism are shown. A contentual model of diffusion of threats to the development of high-tech markets and their consequences in the new environment of forking out material and digital economy is built up, which deepens understanding of the reasons for the combination of globalization and deglobalization processes both in the world and in individual countries.

Published: December 2020

Diyabet tüm dünyada görülme sıklığı giderek artan kronik endokrin bir metabolizma bozukluğudur. Diyabetin ve komplikasyonlarının gelişiminden, artan kan glukoz düzeyinin sonucu olarak ortaya çıkan oksidatif stres sorumlu tutulmaktadır. Organizma oksidan moleküller ve onları ortadan kaldıran antioksidan savunma sistemi arasındaki dengeyi korumaya eğilimlidir. Ancak reaktif oksijen ve nitrojen türlerinin üretimi ve nötralizasyonu arasındaki dengenin bozulup, antioksidan kapasitenin yetersiz kalması sonucu oksidatif stres ortaya çıkmaktadır. Diyabette gelişen hiperglisemiye bağlı olarak glikoliz, hekzosamin, polyol gibi çeşitli metabolik yolakların diyabetli bireylerde aşırı aktivite gösterdiği ve prooksidatif süreci başlattığı belirtilmektedir. Bu metabolik yolaklarda üretilen ürünler tek başına oksidasyonu arttırabildiği gibi diğer yolaklar ve ara ürünlerle de etkileşime girerek oksidatif dengeyi bozmaktadır. Bu derlemede diyabette hiperglisemiye bağlı gelişen oksidatif stresin moleküler düzeydeki nedenleri özetlenmiştir.

Cilj rada bio je istražiti zastupljenost tema održivog razvoja u odgojno obrazovnim programima te razinu primjene sadržaja održivog razvoja odgojitelja u dječjim vrtićima i učitelja nižih razreda osnovnih škola Grada Zagreba. Istraživanje, metodom ankete, provedeno je tijekom školske godine 2017/18. u okviru edukativnih radionica „Upoznajmo domaće životinje“ na pokušalištu Centra za travnjaštvo na Medvednici (Sveučilište u Zagrebu Agronomski fakultet). Anketirano je ukupno 99 odgojitelja i učitelja. Prema rezultatima ankete, 21% odgojno-obrazovnih ustanova ne posjeduje spremišta za odlaganje otpada. Od anketiranih učitelja i odgojitelja, 56% je mišljenja da u odgojno-obrazovni program nije uključen dovoljan broj ekoloških tema, 73% drži da je manji broj djece ekološki osviješten, a 59% misli da nije opravdana viša cijena ekoloških proizvoda. Većina anketiranih učitelja i odgojitelja (i) sebe smatra ekološki osviještenim osobama (81%); (ii) koristi javni prijevoz za odlazak na posao (60%), (iii) u svom kućanstvu razvrstava otpad (67%), (iv) odlaže staru odjeću u spremnik namijenjen za odlaganje odjeće (70%), (v) prilikom kupovine koristi eko vrećice (66%), (vi) kupuje ekološke proizvode (51%) te (vii) koristi reciklirane proizvode (54%). Zaključeno je da većina odgojitelja i učitelja u svakodnevnom životu provodi sadržaje održivog razvoja te da bi odgojno-obrazovni rad iz područja održivog razvoja kroz predškolski i osnovno-školski program trebalo intenzivirati. Da bi se svijest o očuvanju okoliša za održivi razvoj prenijela na djecu, neophodno je osigurati suživot djece s teoretskim i praktičnim principima održivog razvoja. Intenziviranjem rada iz područja zaštite okoliša za održivi razvoj u odgojno obrazovnim ustanovama, odgajaju se generacije djece s izgrađenim pozitivnim stavovima prema prirodi, koje će manje zagađivati okoliš i tako čuvati planetu Zemlju.

Cilj ovog rada bio je utvrditi sposobnost zadržavanja vode (kalo odmrzavanja – TL i kalo kuhanja – CL) i mekoću mesa (Warner-Bratzler sila presijecanja, WBSF) posavskog konja obzirom na spol, dob pri klanju i dužinu zrenja. U istraživanje je sveukupno bilo uključeno 12 životinja (6 muških i 6 ženskih) pasmine posavski konj. Prosječna dob životinja bila je 18 mjeseci (od 6 do 36 mjeseci). Uzorci mesa potrebni za daljnju analizu izuzeti su s najdužeg leđnog mišića (M. longissimus dorsi) nakon zrenja od 14, odnosno 28 dana. Dobiveni podaci analizirani su pomoću SAS/STAT softverskog paketa verzija 9.4. Utvrđene srednje vrijednosti za TL, CL i WBSF su bile kako slijedi: 8,41%, 19,24% i 26,04 N. Rezultati istraživanja ukazuju da spol, dob pri klanju i dužina zrenja značajno ne utječu na sposobnost zadržavanja vode i mekoću mesa posavskog konja (p>0,05). Istraživanjem su dobivene nove spoznaje o kakvoći mesa posavskog konja koje bi svakako trebale pridonijeti budućim istraživanjima u svrhu potpunijeg razumijevanja kakvoće konjskog mesa.

Plasmablastic lymphoma (PBL) is a rare and clinically aggressive neoplasm that typically occurs in immunocompromised individuals, including those infected with human immunodeficiency virus (HIV) and solid organ allograft recipients. Most prior studies have focused on delineating the clinico-pathological features and genetic attributes of HIVrelated PBL, in which MYC deregulation, Epstein-Barr virus (EBV) infection and, more recently, mutations in JAK/STAT, MAP kinase, and NOTCH pathway genes have been implicated in disease pathogenesis. The phenotypic spectrum of post-transplant (PT)-PBL is not well characterized and data on underlying genetic alterations are limited. This led us to perform comprehensive histopathological and immunophenotypic evaluation and targeted sequencing of 18 samples from 11 patients (8 males, 3 females; age range, 12-76 years) with PT-PBL; eight de novo and three preceded by other types of post-transplant lymphoproliferative disorders. Post-transplant PBL displayed morphological and immunophenotypic heterogeneity and some features overlapped those of plasmablastic myeloma. Six (55%) cases were EBV positive and five (45%) showed MYC rearrangement by fluorescence in situ hybridization. Recurrent mutations in epigenetic regulators (KMT2/MLL family, TET2) and DNA damage repair and response (TP53, mismatch repair genes, FANCA, ATRX), MAP kinase (KRAS, NRAS, HRAS, BRAF), JAK/STAT (STAT3, STAT6, SOCS1), NOTCH (NOTCH1, NOTCH3, SPEN), and immune surveillance (FAS, CD58) pathway genes were observed, with the mutational profiles of EBV+ and EBV– cases exhibiting both similarities and differences. Clinical outcomes also varied, with survival ranging from 0-15.9 years after diagnosis. Besides uncovering the biological heterogeneity of PT-PBL, our study highlights similarities and distinctions between PT-PBL and PBL occurring in other settings and reveals potentially targetable oncogenic pathways in subsets of the disease.

Purpose. The features of healing of postoperative wounds after osteoplasty of alveolar processes of jaws with the use of titanium and bioresorbable membranes in patients with galvanic pathology were studied. Methods. There were examined 120 patients, aged 19 to 35 years, with or without metal dentures. In the course of surgical preparation of alveolar processes of jaws for further dental implantation (osteoplasty of alveolar processes), bioresorbable membranes based on polylactic acid and membranes made of titanium were used. Depending on the presence or absence of galvanic pathology, all patients were divided into 4 groups. Results. It was found that in patients without galvanic pathology, postoperative healing occurs without inflammatory complications. In patients with galvanic (compensated and/or decompensated form) in the early postoperative period, 51.6 % of the examined patients appeared complications in the form of severe pain and other inflammatory complications. In patients with galvanosis (atypical and typical forms) both early (82.8 %) and late (10.4 %) postoperative complications occurred in the postoperative period. All postoperative complications were equally common in the subjects who were using titanium membranes and in patients with bioresorbable membranes. Conclusions. It was established that in the presence of non-removable metal dentures in the oral cavity made of base of ignoble metal alloys, leading to the development of galvanism or galvanosis, there are early and late inflammatory complications in the preparation of alveolar processes for dental implantation, which significantly prolongs the time of healing of postoperative wounds.

The aim was to the assess the health impact of substances measured in the air originating from the decomposition of organic components of sewage sludge in the landfill. Methods: The study was performed at the Severny landfill in a suburb of Saint Petersburg. Sanitary and chemical methods of landfill emissions research we applied. Health risk assessment of the chemicals polluting the air was used. Results. In total, 30 pollutants are emitted from the landfill to the air with the total emission of 768.11 tons/year. The main pollutant was methane. The emissions contained 12 pollutants with a carcinogenic effect. A total of 18 substances comprised 99.9 % of the total index of non-carcinogenic hazard with dihydrosulfide (hydrogen sulfide), formaldehyde and ammonia being the main contributors. Conclusions. The maximum values of carcinogenic risk from exposure to formaldehyde at the calculated points reached 5.8x10-6. The levels of individual carcinogenic risk from formaldehyde exposure correspond to the second risk range (maximum permissible). The value of the total individual carcinogenic risk does not exceed the value of 7.4E-06. The maximum values of the hazard factors for chronic exposure are due to hydrogen sulfide - 0.27. The maximum values of the exposure hazard index at calculated points on the respiratory system are 0.46; on the immune system - 0.16; on the eyes - 0.15. These risk levels were rated as minimal.

Traffic safety is an important issue that needs to be taken into account in developing national policy. Several causes of accidents along the "diver-vehicle-road-environment" chain have been identified, although alcohol consumption seems to be the most important preventable cause. The aim of this paper is to describe the main activities to detect alcohol-related problems among bus drivers with the further going aim to develop public health strategies to decrease the number of traffic accidents. Methods. We analyzed normative documents, laws and edicts of the Russian Ministry of Health directed at reduction of traffic accidents associated with alcohol intoxication among drivers. Results. The main analytic approaches to study risk factors for traffic accidents including alcohol consumption practiced by intersectoral organizations are presented. Special emphasis is given to changes in legal limits of blood alcohol concentrations among the drivers in Russia. The analysis suggests that occupation as a drivers of public buses poses greater demands to physical and mental health. Psychological traits of bus drivers were summarized. Difficulties associated with detection of alcohol abuse and use of other substances among bus drivers were analyzed. The fact of driving a bus under the influence of alcohol should be treated as the use of psychoactive substances with health-related consequences. Data related to substance use obtained at medical checkup of drivers at the beginning of the shift can be transferred to narcological dispensaries (abuse clinics). Conclusions: the suggested algorithm of screening for substance abuse among bus drivers can become the basis for development of medical and psychological prevention directed at reduction of the number of traffic accidents associated with alcohol.

Tomando como referencia la estabilización de suelos con cemento como uno de los procesos más eficientes para conformar capas de portantes para estructuras de pavimento así como su consabida debilidad en términos de su tendencia a la fisuración debido a los procesos de retracción, en el presente trabajo se intenta incursionar en el uso de pequeñas dosis de emulsión asfáltica como complemento del cemento en la estabilización de mezclas de suelo-arena. El objetivo es el de evaluar un potencial efecto mejorativo tanto en términos portantes, especialmente ante los efectos del agua, así como en términos retractivos. A tal fin se estudia la respuesta portante del material, incluyendo procesos de inmersión, a partir de ensayos de resistencia a la compresión simple y tracción indirecta, así como la respuesta en términos de durabilidad por humedecimiento y secado, y en términos de retracción para lo cual se desarrolla un procedimiento de ensayo especifico.

En América se ha utilizado la mampostería cerámica cocida desde mediados del siglo XVIII la cual forma parte del patrimonio cultural local. La permanencia en el tiempo se debe a su técnica de construcción, calidad de materiales y mantenimiento además del efecto de los terremotos. Se presentan resultados de inspección detallada de cinco construcciones de mampostería cerámica de valor patrimonial con diferentes patologías que requieren distintas tecnologías de puesta en valor en la zona de mayor riesgo sísmico de Argentina.

La metodología de estudio utilizada para las propuestas de rehabilitación incluye la modelación por elementos finitos, lo que requiere de parámetros de comportamiento de mampuestos y morteros para comprender las patologías subyacentes obtenidos de ensayos de laboratorio y monitoreo in situ. La puesta en valor debe considerar que no se presente incompatibilidad de materiales aplicando tecnologías locales.

En los últimos años, debido al gran número de accidentes catastróficos en el sector industrial, la obtención de una metodología cuya aplicación contribuya a la mitigación de los daños causados ha adquirido gran importancia. En este trabajo, se obtienen dos correlaciones que describen el comportamiento de un evento específico (explosión tipo BLEVE) por medio de una combinación lineal de funciones convexas simples entre las principales variables: energía interna total del sistema al momento de la explosión, distancia y nivel de daño/tipo de receptor. La primera permite estimar la distancia de seguridad frente a una explosión de cualquier sustancia peligrosa y la segunda, el nivel de daño (expresado en términos de sobrepresión) ocasionado a un receptor ubicado a una cierta distancia del evento catastrófico. En trabajos futuros, se pretende emplear las mismas en la optimización de diseño inherentemente seguro de layout.

Penelitian ini bertujuan untuk mengetahui magnitudo erosi dan sedimentasi garis pantai Ujung Tape dalam proyeksikan lima tahunan dan di mana letak bangunan pelindung pantai yang bisa diterapkan di lokasi tersebut. Metode penelitian  yang digunakan adalah memodelkan gelombang dan garis pantai pada software STWAVE dan GENESIS yang berbasis model numerik. Kalibrasi model dilakukan dengan memodelkan garis pantai terukur (measured shoreline) dan garis pantai awal (initial shoreline) untuk mendapatkan koefisien kalibrasi (k1 dan k2). Nilai k1 dan k2 yang memiliki kesalahan error (Ɛc) yang terkecil dan memiliki tren yang lebih mendekati perubahan garis pantai di lokasi digunakan sebagai variabel bebas terpilih untuk mensimulasikan garis pantai dalam lima tahun ke depan. Simulasi garis pantai juga dilakukan dengan penambahan model bangunan pelindung pantai yaitu pemecah gelombang (skenario A dan B). Hasil simulasi dari tahun pertama sampai tahun kelima menunjukkan garis pantai dominan mengalami erosi walaupun di beberapa grid mengalami sedimentasi. Sel grid ke 480 sampai 2640 mengalami erosi  dimana yang terbesar adalah sel grid ke 1540 dengan erosi -7331.99 m3. Perubahan garis Pantai Ujung Tape dari tahun pertama sampai tahun kelima menunjukkan pantai dominan mengalami erosi dengan volume angkutan sedimen sebesar –462.863 m3. Bentuk perlindungan garis pantai Ujung Tape yang dapat mencegah erosi adalah melalui model breakwater skenario A dan B  dengan tangkapan sedimen sebesar 509.583 m3/tahun (skenario A) dan 463.370 m3/tahun (skenario B).
