Bevk Perović arhitekti was founded by Matija Bevk b. 1972, graduated from Faculty of Architecture University of Ljubljana) and Vasa J. Perović b. 1965, graduated from Faculty of Architecture University of Belgrade, YU; Master's degree from Berlage Institute, Amsterdam). They work, alongside with the international team of 15 young architects, on a diverse range of projects in different European countries. They have been awarded numerous national and international prizes - European Union Prize for Contemporary Architecture - Mies van der Rohe Emerging Architect Award, Kunstpreis Berlin, Plečnik Prize, Piranesi Award, and others. In order to understand and comprehend their work, one must examine their 'dedicated choice' to follow conditions in which a building emerges. These conditions range from political and social, to environmental and material their simple, yet complex architectural solutions strive to respond to those conditions beyond bare function. For this publication we have selected two of the most recent finished public buildings: Islamic Religious and Cultural Centre Ljubljana and Neue Galerie und Kasematten / Neue Bastei, Wiener Neustadt 2016 - 2019.

Quality of life of patients with gynecological cancers
Authors: Kilikova Maria
Published: January 2021

Introduction: The quality of a women's life is very closely related to their health. Oncogynecological disease brings substantial changes into their life that women need to adapt to them. As determination of quality of life is in nurse competence, the quality of life in women with diagnosed oncogynecological illness and surgical treatment has been described in the paper. Aim: The aim of the paper was to examine cancer's influence on the quality of life based on physical health, survival, social relationships, and the environmental domains. Methods: The sample consisted of 84 female respondents with surgical treatment of oncogynecological disease and the patients fulfilled the standardized WHOQOL-BREF questionnaire. Results: The results have shown that patients experienced significant reductions in the quality of life in regard to physical and mental health. Social and environmental domain were significantly less affected. Conclusions: The oncogynecoogical diseases significantly affect quality of life in all four investigated domains, but to a different extent. These findings emphasize an individual approach that takes into account not only the nursing aspect but also the ability to respond to a variety of other related factors that affect the quality of women with oncogynecological disease.

The data obtained through interviews were content-analyzed, and the Q data were analyzed via the PQMethod 2.35 software program. The results indicated that organizational, managerial, and systemic factors had both negative and positive effects on teacher performance. Teachers expressed similar views via the item configurations provided and built up a similar profile about the factors affecting job performance. Besides general professional competencies, students' readiness level and teachers' mastery of course content were reported to have impacts on classroom teachers' job performance.
The relationship between social ostracism and friendship quality and false identity in secondary school students
Authors: Özyazici Kadriye , Kanak Mehmet
Published: January 2021

Objectives: Adolescents endeavor to meet their social needs, to be accepted and to develop close friendship relationships. However, quality and close relationships may not always be possible. Identity development may be affected if adolescents cannot be included in social groups and cannot establish quality friendship relationships. This can be caused to false identity of adolescents who have not yet gained the ability to develop a original identity. Methods: The study group consisted of three high schools, determined according to the entrance score of secondary education in Sivas city center and 510 students enrolled in secondary education with general aptitude exams in the 2017-2018 academic year. Social Exclusion Experiences Scale for Adolescents, False Identity Scale for Adolescents and Friendship Quality Scale were used as data collection tools. Results: According to the regression analysis findings, it was observed that false self and acceptance variables predicted significant negligence, which is the sub-dimension of social exclusion variable. It significantly predicts the exclusion sub-dimension of the social exclusion variable of proximity and acceptance variables. Conclusıon: The results of this study will contribute to adolescent identity development and will provide guidance to parents and teachers in order to establish a healthy friendship relations.
Media and culture: Dialectics of values
Authors: Vuksanović Divna
Published: January 2021

Along with studying the world of culture, Milena Dragićević Šešić has also dealt with reflections in the field of media theory. These two parallel lines of study, as well as long-term teaching activities in the designated areas, in my opinion, represent a paradigm, where they approach each other, conflict and fight for the dominance of two different value systems existing today. In principle, on the side of culture and its interests and possibilities, M. D. Šešić does not fall into the trap of technophobia, but, on the other hand, does not fetishize the existing media reality. By analysing the current media scene - either theoretically or practically, the author Šešić discreetly supports culture in its struggle for a more equal status in relation to the media dictum, in the era of the rule of modern communication technologies. Without disputing the idea and practice of accelerated technical and technological progress, M. D. Šešić critically valorises the world of media, advocating a cultural value paradigm in the field of the media communication.
The role of critical thinking in the digital media culture and strengthening of digital immunity
Authors: Zarić Maja
Published: January 2021

The public health emergency and the proclaimed state of the global pandemic caused by the COVID-19 virus have led to the biggest world crisis since World War II. With the introduction of quarantine measures in spring 2020, the digital transformation has accelerated in many societies and the importance of media and information literacy in these new circumstances has been clearly emphasized. The pandemic has changed the information and media habits of the citizens, work from home was introduced, online school classes became mandatory, and an uprise of e-commerce reflected the new reality. The digital space has become oversaturated with informative, educational, commercial contents and many cultural institutions and international organizations have made their cultural heritage accessible online. Interaction in the public digital space has became more and more intense, and critical thinking stood out as a necessity for strengthening the digital immunity of each individual as well as the society. The pandemia was followed by infodemia. The information channels used by citizens point to a certain re-examination of the new digital media culture, the very concept of media as well as the accompanying regulations and media policy. The findings of the paper draw attention to the media and information literacy policy framework in Serbia, and review a set of activities that the Ministry of Culture and Media has been conducting over the past two years on both national and international level. It describes the correlation between the framework and the practice and depicts the trends in the international policy in this field. The paper focuses on the strategic vision and provides information throughout the two-year period on setting up of the holistic 360 approach and setting up media literacy network of stakeholders with the aim of strengthening advocacy and developing of the media literacy field.
Evaluation of corporate success using synergistic CPA and CPR corporate citizenship
Authors: Taillard Michael , Mitrović Miroslav
Published: January 2021

Corporate Political Activities (CPA) and Corporate Public Relations (CPR) are both non-market communication strategies that effect market positioning, brand strength and the business success of a company. In this study, the use of CPA and CPR by several companies are analyzed based on their economic and brand strength metrics, which confirms the hypothesis that use of these strategies has a positive impact on their market position and brand stability. Using the Multi-Value Comparative Quality Analysis (mvCQA), the research strives to measure the synergistic influence of CPA and CPR on a company's performance. Building on the existing literature for the uses and implementation of mvCQA, this research reinforces the role mvCQA plays in delivering quality and comparative findings of correlation between CPR and CPA toward market strength. This study confirms that the synergy between CPR and CPA improves corporate strategic development. It is inferred that CPR and CPA maintain non-linear correlation with industry and market niches, specific cultural and business environments, as well as overall corporate strategy goals.

Approach to implementation of local navigation of mobile robotic systems in agriculture with the aid of radio modules
Authors: Iakovlev Roman , Saveliev Anton
Published: January 2021

In this paper an approach is presented, enabling to solve the problem of local navigation of mobile robotic platforms (MRP), based on utilization of wireless networks with mesh topology. Establishment of wireless networks was ensured, based on the set of radio modules, mounted on unmanned aerial vehicles (UAV), comprising a swarm. This paper presents a developed algorithm for establishment of such wireless networks, aided by LoRa-technology, as well as an algorithm for MRP localization, based on analysis of signal level, where the incoming signals are fed from MRP group radio modules to radio modules of wireless data transfer network. An algorithmic model is given for task distribution among UAV and to implement navigational capabilities of MRP swarm. In some experiments descending dependencies of absolute error value, pertinent to MRP, from the number of UAV in action were revealed, as well as of averaged deflection value of MRP positions in motion along their paths from the number of UAV in action. Thereby the averaged value of MRP localization error, depending on the number of UAV in action, was from 8.14 to 17.13 m, and the averaged value of MRP position deflection - from 16.38 to 57.12 m, respectively.
O naturalismo biológico em John Searle: A objetividade epistêmica e a subjetividade ontológica como artífices da consciência

Published: January 2021

Or present article salient to the theme of consciousness, as a crucial fator we are mindful, based on a historical retake, encompassing the principalities that justify and conceive this phenomenon. Initially, discussed in the "mind-brain" problem, a conscience is given to the leading role of Philosophy of Mind, alicerçada em duas great corntes: monista and dualista. Both, theoretically, from the ramifications of Cartesian thought, which divides the mind and mind into these dichotomous substances or as reduced to pure materialism, discarding subjectivities. Searle, based on his Biological Naturalism, stands out as an innovative thinker, who unleashes the current theories, proposed to analyze two states as a result of epistemic objectivity together with no ontological subjectivity.
La emigración irlandesa decimonónica tras la gran hambruna, parte intrínseca del carácter irlandés
Authors: Díaz Morillo Ester
Published: January 2021

Resumen: A lo largo de la historia han tenido lugar episodios de grandes crisis que transformarían irremediablemente la vida de millones de personas. Uno de estos acontecimientos fue la gran hambruna producida en Irlanda entre 1845 y 1851, uno de los eventos más trágicos de nuestra historia contemporánea que dejaría profundas huellas en su población. Uno de sus efectos más graves fue la oleada migratoria sin precedentes que llevó a numerosos irlandeses especialmente hasta las costas norteamericanas. Este artículo pretende, por tanto, estudiar la migración irlandesa producida por la gran hambruna y las características especiales que mostró y que la hizo distinguirse del resto de olas migratorias europeas decimonónicas. La «nueva Irlanda» que se conformaría en lugares como Estados Unidos nunca perdería su vínculo con la isla y dejaría un legado imborrable en ciudades como Nueva York y Chicago.Abstract: Throughout history there have been episodes of major crisis which would inexorably transform the lives of millions. One of such events was the Great Famine that took place in Ireland between 1845 and 1851, which was one of the most tragic events in our contemporary history and which would leave important marks on its population. The great unprecedented migration wave which led countless Irish people, especially towards the North American coasts, was one of its gravest effects. The aim of this article, therefore, is to explore the Irish migration induced by this Great Famine and the special characteristics that it showed and that made it distinguishable from the rest of the migration waves from nineteenth-century Europe. The “new Ireland” which developed in places such as the United States would never lose its bond with the island and would leave an indelible legacy in cities like New York and Chicago.
El islam en el espacio público de los barrios multiculturales del sur de Europa: el caso de Lavapiés, Madrid
Authors: Salguero Montaño Oscar
Published: January 2021

Resumen: En las actuales sociedades plurales no confesionales, los grupos religiosos entienden el acceso al espacio público como un derecho a la ciudad. Este derecho legitima su condición de actores sociales, que traducen como visibilización en el espacio público y participación en la vida política del municipio, a través de diversas nociones vinculadas a la modernidad y la transparencia. Para explorar esta hipótesis, este artículo examina el caso de los musulmanes bangladeshíes del multicultural barrio madrileño de Lavapiés, el cual presenta semejanzas con otros barrios multiculturales de ciudades del sur de Europa como Lisboa o Roma: un barrio afectado por un acelerado proceso de gentrificación y turistificación. Se analizan las circunstancias en las que esta comunidad intenta acceder al espacio público, con el fin de lograr una mayor legitimación y reconocimiento, teniendo en cuenta las diferentes prácticas y discursos que se despliegan en determinados eventos y festividades.Abstract: In current nondenominational plural societies, religious groups understand access to public space as a right to the city. This right legitimizes their status as social actors, who are entitled to have a public life and to be recognized, through various notions linked to modernity and transparency. To explore this hypothesis, this article examines the case of Bangladeshi Muslims in Madrid’s multicultural neighborhood of Lavapiés, which has similarities with other multicultural neighborhoods in southern European cities, which has similarities with other multicultural neighbourhoods in southern European cities, such as Lisbon or Rome: a barrio affected by an accelerated gentrification and touristification process. It analyzes the circumstances through which this community attempts to access public space, in order to achieve further legitimization and recognition, by bringing into account the different practices and discourses displayed in specific events and festivities.

LA SOMIGLIANZA ICONICA NELLA SCRITTURA DE-SOGGETTIVANTE TRA IDENTITÀ E DIFFERENZA
Authors: PONZIO Luciano
Published: January 2021

Riassunto: Il pericoloso potere di assimilazione renderebbe le cose identiche le une alle altre, uniformandole, smarrendone la singolarità. Il mondo senza alterità si ridurrebbe a una massa omogenea: l’Identico e la sua rappresentazione. L’esistenza di un segno non è semplicemente riflessa ma rifratta (Vološinov). In questa rifrazione gioca il ruolo determinante l’alterità. Produrre e comprendere segni significa partecipare ai processi comunicativi. Il segnico è il campo dell’ambivalenza in cui tutto si decide per relazioni e pratiche sociali (Bachtin). Uscire dalla filosofia del soggetto (Foucault), porsi in una posizione “fuori-di-sé”, configurare una scrittura in-ferma contro il soggetto statico, per recuperare il corpo sociale nelle parole e nelle immagini.Abstract: The dangerous power of assimilation uniforms things, making them lose their singularity. The world without otherness would be reduced to a homogeneous mass where representation always represents the Identical. The existence of a sign is not simply reflected but refracted (Voloshinov). In this refraction, otherness plays the decisive role. Producing and understanding signs means participating in communication processes. The sign is the field of ambivalence in which everything is decided by relationships and social practices (Bakhtin). In this field is possible as this paper tries to show, to get out of the philosophy of the subject (Foucault) in order to recover the social body of words and images.
L’INTRECCIO DEL GESCHLECHT: TRADUZIONI E ATTRAVERSAMENTI DELL’IDENTITÀ
Authors: PONZIO Julia
Published: January 2021

Riassunto: Tra il 1983 e il 1989 J. Derrida dedica quattro saggi alla parola tedesca Geschlecht e alla sua difficoltà di traduzione. L’intraducibilità di questa parola dipende dalla sua polisemia. Per tradurla, infatti, è necessaria una lunga serie di significanti tra i quali: sesso, razza, specie, genia, genere, famiglia, generazione, genealogia, parentela, stirpe, comunità. L’idiomaticità di questa parolaè un inestricabile intreccio che non consiste nella sua capacità di “stare per” cose diverse a seconda dei contesti in cui la si usa ma nella capacità di innescare la questione del rapporto tra identità e alterità.Abstract: Between 1983 and 1989 J. Derrida dedicates four essays to the German word Geschlecht focusing on its difficult translation. The untranslatability of this word depends on its polysemy. To translate it, in fact, a long series of signifiers is necessary, including: sex, race, species, genìa, genus, family, generation, genealogy, kinship, lineage, community. The idiomaticity of this word is an inextricable intertwining that does not consist in its ability to “stay for” different things depending on the contexts in which it is used, but in the ability to trigger the question of the relationship between identity and otherness.

Authors: Gurova Tetyana , Estefen Segen F. , Leontiev Anatoli , Barbosa Plinio T. , Zhukov Valentin , Nikulin Vasilii
Published: January 2021

Repair by welding is widely used in the shipbuilding industry during ship construction. The effect of the residual stress distribution induced by the welding process on the ship structure is important for the repair effectiveness. This article presents an experimental study of the residual stress distribution induced by repair welding in the plates that are typically used in ships and offshore structures. Different repair techniques are evaluated to identify the best practice associated with residual stress values. Recommendations for repair welding are discussed, and modifications to the present practice are proposed.

Authors: Seo Jeonghwa , Kim Dae Hyuk , Ha Jeongsoo , Rhee Shin Hyung , Yoon Hyeon Kyu , Park Jongyeol , Seok Woo-Chan , Rhee Key Pyo
Published: January 2021

The present study is about the application of a four-degree-of-freedom (4DOF) maneuvering mathematical model based on Abkowitz’s model for assessing damaged ship maneuverability with initial asymmetry. A scaled model of the Office of Naval Research Tumblehome hull with a damaged compartment was used as the test model. Based on the survivability regulations for naval vessels, the damaged compartment was designed and located near the bow, such that it had an initial heel and trim. Static and dynamic captive model tests were performed on the damaged ship model to determine the maneuvering coefficients for the maneuvering mathematical model. Maneuvering simulations were carried out with the captive model test data and 4DOF maneuvering mathematical model. The advance speed in the maneuver reduced more in the damaged condition than in the intact condition, and maneuverability was severely degraded during starboard turning.
Influence of Systematic Hull Shape Variations on Ship Stability Performances in Waves
Authors: Petacco Nicola , Vernengo Giuliano , Villa Diego , Coppedé Antonio , Gualeni Paola
Published: January 2021

The sensitivity of ship stability performance in waves to geometric variation has been investigated by means of a simulation-based design framework. The study was devoted to assess the influence of hull geometry variations on some stability failure modes, namely, parametric roll (PR) and pure loss of stability (PLS). The application has been developed by using a representative model of a postpanamax container vessel. PR and PLS phenomena have been investigated by the application of second-generation intact stability criteria (SGISc). The initial multidimensional design space has been filled by 500 design configurations identified by means of a design of experiments approach. A method developed in-house, combining the subdivision surface and free-form deformation approaches, has been used to create the whole set of design alternatives. The generated design configurations have been assessed analyzing the results derived from application of the first- and the second-level SGIS vulnerability criteria for both the selected stability failure modes. To strengthen the correlation behaviors, the design space has then been further explored by using 10k design configurations exploiting the capabilities of a surrogate model–based approximation, relying on a Gaussian process formulation. The study has been focused on the correlations among the variables and the response functions, i.e., the outcomes of the SGIS vulnerability criteria. The significance, in terms of effects, of each geometry shape variable has been investigated. Results have been discussed in the light of the SGISc structure, to provide further insight into this innovative safety framework for a modern approach to intact stability.

Introduction

In the last 10 years, the development of the so-called second-generation intact stability criteria (SGISc) has been one of the most engaging topics addressed by the Sub-Committee on Safety Design and Construction (SDC) of the International Maritime Organization (IMO).
Shipbuilding Should Turn Inland
Authors: Ross Jonathan M. , Boylston John W.
Published: January 2021

As the marine industry laments on the noncompetitiveness of our coastwise shipbuilding capability, an efficient inland marine building community remains competitive in this market. Labor rates which are a percentage of coastwise yards' rates and production rates as high as 200 percent of coastwise yards clearly show the effects of craft unions and formalization of work rules built up after many years of operation in coastal yards. Faced with high production costs, the coastal yards find it difficult to modernize not only due to the capital involved but due as well to the difficulty of realizing the full benefits of modern machinery which must be operated through antiquated work rules. This paper theorizes that since it is impossible to upgrade work rules and difficult to upgrade equipment, perhaps shipbuilding should turn inland and start anew.

Authors: Peart J. W. , Jaekel L. L. , Noma M. , Kobuhe K. , Hirota I.
Published: January 2021

Shipbuilding is a multifaceted industry requiring the coordination of many activities and relying on ever-evolving technology. Painting is an integral and costly part of this operation. This paper describes the Zone Painting Method, a new concept in ship construction which is based on the Product Work Breakdown Structure. The essence of the Zone Painting Method is proper planning and scheduling in coordination with hull construction and outfitting. Design and planning structures, as related to zone painting, are presented. Departmental responsibilities for those segments of the shipyard organization which impact painting are detailed. Finally, the planning process according to the three phases of contract planning, system planning and zone planning is delineated.
Implementation of an Integrated Fabrication Control Philosophy in a Modernized Shipyard Pipe Shop
Authors: Saginaw David J.
Published: January 2021

In October 1983, National Steel and Shipbuilding Company, as part of a yard-wide advanced technology implementation program, initiated a project to modernize its existing pipe fabrication operation. The modernization included facility enhancement and equipment acquisition, and involved the implementation of an integrated manufacturing control philosophy beginning in design and employing principles of group technology with respect to pipe fabrication. The paper summarizes the efforts associated with the pipe fabrication modernization project by tracing the facility enhancement from the initial feasibility studies to detailed shop layout and by describing the operating procedures currently being implemented in the pipe shop to support an integrated manufacturing control philosophy. An assessment of the favorable impact on productivity of the new facility and methodology is discussed as well as several facility and technology enhancements identified as appropriate steps to further improvement in pipe fabrication productivity.
Group Technology in Shipbuilding
Authors: Lamb Thomas
Published: January 2021

The basic concepts of group technology are not new. The first use of the principles of group technology was described by an American, R. E. Flanders, in 1925. U.S. interest in group technology was slow to start, with initial flickerings in 1971 to 1973. If group technology is not new, why has it not been applied to the shipbuilding industry before now? In addition to the above-mentioned general lack of use, a complete lack of knowledge of it, and of its benefits is the most obvious reason. Actually, some shipyards in the world have utilized it and the paper describes some shipbuilding applications and gives examples of some new applications.
Automatic Submerged Arc Welding with Metal Powder Addition to Increase Productivity and Maintain Quality
Authors: Thomas Phillip D.
Published: January 2021

This paper presents the results of a SNAME SP-7 Welding Panel research and development project recently completed by Newport New Shipbuilding. It was directed toward the evaluation, testing, and qualification of automatic submerged arc welding (SAW-AU) with metal powder additions for shipyard use. It is concluded that using controlled metal powder additions with SAW-AU is indeed a production concept that can reduce shipbuilding costs. This is possible through increased deposition rates and (possibly) reduced consumables costs while, at the same time, maintaining or improving quality.

This paper addresses the higher-level standards application, and focuses on standards for production scheduling. The presentation is based on the authors' involvement in a number of projects in several shipyards.
Proven Benefits of Advanced Shipbuilding Technology: Actual Case Studies of Recent Comparative Construction Programs
Authors: Nierenberg A. B. , Caronna S. G.
Published: January 2021

This paper documents the transformations that have occurred and the benefits that have been realized as a result of the implementation of advanced shipbuilding technology at Avondale in the period from 1976 through 1986. The vehicle for this evaluation is the in-depth study and comparison of two pairs of similar construction programs. Each pair is characterized by one program being performed by traditional shipbuilding design and construction methods and its comparative vessel program being developed utilizing advanced ship design and construction methodology at Avondale. The comparison of these ship construction programs includes discussions of the transformations which have occurred in each of the major shipbuilding disciplines, including engineering, production planning, material, manufacturing, quality assurance and facilities, as well as an in-depth quantification of the benefits derived from the overall shipbuilding process. The evolution that occurred in this ten-year period includes not only the changes in methods and procedures solely for improved shipbuilding productivity, but also the extensive material, procedural and organizational changes required to perform under full U.S. Navy contract requirements as compared to the pure commercial environment which existed at the shipyard at the start of the period.
Computer-Aided Process Planning: A Path to Just-in-Time Manufacturing for Shipyards
Authors: DeVries Richard L.
Published: January 2021

The use of computers to improve the productivity of U.S. shipyards has never been as successful as hoped for by the designers. Many applications were simply the conversion of an existing process to a computerized process. The manufacturing database required for the successful application of computer-aided process planning (CAPP) to the shipyard environment requires a "back-to-basics" approach, one that can lead to control of the processes occurring in the fabrication and assembly shops of a shipyard. The manufacturing database will not provide management feedback designed for the financial segment of the shipyard (although it can be converted to be fully applicable): it provides "real-time" manufacturing data that the shop floor manager can utilize in his day-to-day decisions, not historical data on how his shop did last week or last month. The computer is only a tool to be used to organize the mountains of manufacturing data into useful information for today's shop manager on a "real time" basis. The use of group technology to collect similar products, the use of parameters to clearly identify work content, the use of real-time efficiency rates to project capacity and realistic schedules, and the use of bar codes to input "real time" data are all tools that are part of the process—tools for the shop floor manager of tomorrow.

Philadelphia Naval Shipyard's application of zone logic to ship overhaul is neither small nor isolated. PNSY started its implementation of zone logic in the late fall of 1986, targeting the Service Life Extension Program (SLEP) for USS Kitty Hawk (CV-63) as the initial application. The technical services of Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI), Japan were contracted to assist in this transition. This implementation on the Kitty Hawk is not a trial effort but involves about one third of the production man-days and covers over one half of the compartments on the ship. The actual SLEP production work on Kitty Hawk began in January 1988. Even though it is early in the three-year SLEP, zone logic already is proving its worth. This paper explains the zone logic methods and methodology applied at PNSY on Kitty Hawk. It also discusses the future of zone logic at PNSY and its continued application.
Improvements in Productivity Through Staff Integration
Authors: Kelly David S.
Published: January 2021

Too frequently, today's shipyards are a product of their history. Their organizations represent the experiences and successes of the personnel. In the past this has been adequate because the maritime business was largely subsidized by Federal Government programs. Reductions in these programs have directly reduced the business available to shipyards. As a result, shipyards are failing at a record rate. The prognosis is not good. This paper addresses one facet of improving a shipyard's position in an increasingly competitive environment: improvements in overall productivity resulting from integration of the functions of the shipyard staff. First, an organization is described, identifying the staff and defining its purpose within the shipyard. In a typical shipyard, the staff includes organizations for estimating, planning, engineering, purchasing, and contracting. The responsibilities of each of these groups are discussed and, in particular, the areas of interface between them are highlighted. Using the information developed, the paper examines known problems, based on shipyard experiences, which are responsible for reduced productivity. The paper then provides an outline for integration of staff functions, using simple process control and data processing which will reduce staff overhead and provide improved estimating, material flow, and scheduling support to Production.
Zone Logic Applications for Submarine Overhauls

Published: January 2021

Japanese shipbuilding methods have typically been applied in new ship construction. As shipbuilding declines, the ship repair market has become more competitive and shipyards have started to apply some of these principles to ship repair. Public shipyards have been the most active in this technology development. This paper addresses some of the history and problems that have been encountered at Portsmouth Naval Shipyard in the application of zone outfitting methods.
IHI Zone Logic Application to Electrical Outfitting on Highly Sophisticated Ships
Authors: Sato Shuji , Suzuki Shizuo
Published: January 2021

Outfitting electrical cable in highly sophisticated ships, such as research vessels and patrol boats, has a significant impact on every aspect of ship construction, modernization, overhaul, and repair. In other words, cost, schedule adherence, and quality for very sophisticated ships are fully dependent on the performance of the electrical work. Ishikawajima-Harima Heavy Industries, Co., Ltd. (IHI) has been exploiting zone logic, also recognized as group technology, for construction of virtually all ship types. But, the extensive cable footage in sophisticated ships requires special considerations and techniques. This paper presents practical design and production processes for zone outfitting electric cable. Special focus is on:functional and detail design,conversion of system-oriented design data to zone-oriented work packages called "pallets," andwork methods currently employed in IHI shipyards.
Design for Steelwork Production During the Concept Design Phase
Authors: Hills William , Buxton I. L. , Maddison Robert G.
Published: January 2021

Methods of improving the level of pre-contract design definition and the quality of information relating to steelwork are described. This information is combined with a comprehensive database of manufacturing process information to provide a system for estimating the work content of the main structural steelwork of ships such as roll-on/roll-off vessels. Procedures are described which facilitate consistent estimates to be made while minimizing data-handling requirements and increasing the flexibility of the method at the concept design stage. Applications are described which demonstrate the use of the system in investigations which examine the variation of factors which influence labor cost. The factors examined include the effect of changing midship block breakdown and length of productive day. Suggestions are made as to how the system can be used to assess the importance of those factors which may improve overall yard production efficiency and assist in the planning function.
Development of Design and Fabrication Method for Thin Steel Plate Structure and Its Application to a Passenger Ship
Authors: Hamasaki Tomoya
Published: January 2021

The author's company was awarded a contract to build a cruise passenger ship which had a superstructure with 4.5-mm-thick steel plate decks. Since this first-time application of 4.5 mm to the hull structure was expected to cause a lot of troubles in conjunction with plate distortion, an effort was made to establish the most appropriate standards of design and methods for thin steel plate structure. Structural design and construction methods were carefully reviewed, selected, tested and applied to the ship, and thereby they were verified throughout the actual construction processes. Successful results were obtained from both quality and cost standpoints.
Index-Based Management Information Systems: A Study in Structured Operations
Authors: Bensten Charles E.
Published: January 2021

In any job, project, program or complex undertaking there exists a need to understand all aspects of the work. This understanding is necessary to satisfy all requirements in the most effective and efficient way. The methods available to plan and accomplish these tasks vary as much as the tasks themselves. They range from job shop techniques to Material Requirements Planning (MRP) to Project-Based Management Information System (PBMS) to continuous manufacturing. This paper is a critical analysis aimed at classifying two of these system approaches as they relate to the ship repair equation.
Developing and Using an Expert System for Planning the Production of Structural Piece-Parts
Authors: Spicknall Mark
Published: January 2021

This paper presents an example of how expert systems can be developed and used for planning structural piece-part production. First, expert systems are briefly and generically described. Then the production processes within a shipyard-like structural piece-part production facility are defined within an expert system "shell"; that is, the "objects," "attributes," and "rules" describing the production process are established and explained. Then various structural piece-parts are described to the system and the system identifies the required production processes for each described part. The inference process underlying the identification of these processes is described for each of these parts. Finally, potential applications of expert systems to other areas of shipbuilding operations are discussed.
Cost of U.S. Coast Guard Regulations to the U.S. Maritime Industry and Coast Guard Initiatives to Reduce These Costs
Authors: Henn A. E. , Marhoffer W. R.
Published: January 2021

For a number of years it has been alleged that compliance with U.S. Government regulations—specifically those of the U.S. Coast Guard—adds so much to the cost of a new U.S.-flag vessel that U.S. shipyards are rendered noncompetitive. An often touted figure is an average 15% cost increase due to ship design and construction regulations. Case studies and owners' reports have also identified incremental costs associated with both reflaggings to U.S.-flag and the construction of U.S.-flag ships in foreign shipyards. It is the purpose of this paper to summarize past studies addressing the cost of regulatory compliance, discuss possible explanations for the variations between the conclusions of these studies, identify factors other than regulatory compliance which impact the competitiveness of the U.S. shipbuilding industry, and describe several recent Coast Guard initiatives to further reduce the already low cost of compliance with Coast Guard regulations
