Classic Yacht Redesign and Restoration:Ergonomic and Operational Aspects
Authors: Carola Morozzo della Rocca Maria
Published: February 2022

The rebuilding and restoration of historical yachts have developed significantly over the past few years only, and there is ongoing discussion addressing issues in this respect. To understand the need for new scientific rigor in this field and turn largely self referential interventions into a discipline is a challenge relevant to academic research, organizational entities and regulatory agencies, both governmental and nongovernmental, in Italy and in Europe. There is a multiplicity of aspects that are central to the renovation of historical craft, including primarily ergonomics as key to the design of how to operate boats as ‘places to live and voyage in’, and technology and instrumentation as fundamental elements of navigation systems, additional to standards issued by classification societies. The restoration of classic yachts with a historical and cultural value must correctly consider all ergonomic, functional and technological aspects in reference to both conservational issues and the need to upgrade existing designs to ensure that comfort and navigational safety standards are met. A critical approach that helps find the right compromise under such constraints that are often antithetical and conflicting is central to this research.

Authors: Frassine() Roberto , Fusaro() Claudio , Ratti() Andrea
Published: February 2022

The work aims to discuss measures to reduce risks associated with the workers’ exposure to harmful chemical agents in FRP manufacturing processes. Data on workers’ exposure were collected directly on the site plant of a few manufacturers of fiberglass pleasure boats and other FRP components. Work focuses on various stages of progressive study: I) study of the molding manufacturing process, workplace, structures, tools, materials and plants in the different companies; II) statistical study of the use of Personal Protective Equipment; III) environmental and personal sampling campaign. The study phase I is preliminary to the following. It allowed to identify, for each operators category, the risk factors to which each category is most exposed. Styrene and other VOCs are the main chemical risk factor on which attention has been paid for resins and gelcoat workers. The phase study II about the use of PPE leads to define evolution models in the use of PPE in relationship with room temperature and referring to Behaviour-Based Safety techniques to increase the percentage of use of PPE. The phase study III leads to define what the critical exposure moments are for workers, specially the processes when resin or gelcoat are sprayed. From this stage, intervention proposals arise measured to reduce risks.
Using Eye-Tracking Data and Mouse Cursor Location To Examine Visual Alerting in a Multi-Display Environment
Authors: Crebolder Jacquelyn , Salmon Joshua
Published: February 2022

A study was conducted to assess the effectiveness of visual alerting during a task that required full attention and that used multiple displays. Alert detection time was collected, and eye-tracking data was recorded to determine where participants were looking, particularly when an alert appeared. Results showed that a full border around the display was detected faster than a short bar at the top of the display. This finding is in contrast to previous work in our lab, where the bar alert has always been superior for detection. Previous findings had inferred that the bar alert can be included in a spotlight of attention created during the task. The new findings suggest that the spotlight was expanded in the current experiment as a consequence of limitations in head movement imposed by wearing the eye-tracking equipment. As a result the bar was not captured and detection time was slower. The eye-tracking data was also used to validate mouse cursor location as a reasonable indication of where eyes are looking. The data showed a relatively strong correlation between eye and cursor and indicated that for the task used the cursor is a suitable tool for collecting data on where an individual is looking.
Pedestrian Navigation Guidance for Elderly People’s Safe and Easy Wayfinding
Authors: Furukawa Hiroshi
Published: February 2022

In order to reduce anxiety of pedestrian navigation users, we have proposed a route planning algorithm, which weighs user’s difficulty of locating own current position as well as total physical distance of courses. The cost function for evaluating routes is expanded by adding elapsed time of locating each intersection to the original cost of route distance. The elapsed time at an intersection is estimated based on valuation functions of effectiveness of landmarks. The functions were constructed based on data collected through cognitive experiments with younger participants. The fundamental validity of the proposal method was confirmed through practical experiments. The aim of this study was to extend the object of the navigation guidance method to elderly people, as well as younger people. Considering the degradation of cognitive functions of elderly users, we modified three functions: the valuation functions for recognizability of landmarks, the valuation function of landmark’s effectiveness, and the cost function for route planning. Three cognitive experiments were conducted to acquire actual data for the modification. The results indicate that the functions acquired are quite fit to the data of the experiments, and suggest that the modified method is useful for estimating walking time for routes by elderly users.
Evaluating Design Hypotheses for Rail Level Crossings: An Observational Study of Pedestrian and Cyclist Behavior
Authors: J. M. Reada Gemma , M. Salmonb Paul , G. Lennéc Michael , M. Greyd Elizabeth
Published: February 2022

Accidents involving pedestrians at rail level crossings are a significant public safety concern in Australia and internationally. The current design of rail crossings incorporates assumptions and hypotheses about how people will interact with the infrastructure at the crossing. The hypotheses associated with the design of pedestrian rail crossings in metropolitan Melbourne were evaluated through the findings of naturalistic observations of users. Comparison of actual behavior as recorded in the observations was compared to the design hypotheses relating to the features at the crossing. While for some the majority of behavior was in line with the hypothesis, it was found that a number of the hypotheses were not always supported. The evaluation uncovered unexpected interactions between users and the infrastructure, as well as implications for rail crossing design. The findings support the need for a systems approach to the analysis and design of rail crossings from a pedestrian and cyclist safety perspective to assist understanding of the system and to inform its re-design.

Published: February 2022

A study has documented that there are only four possible working postures for motorcycling, yet, all of these postures are argued by another study to be generally “unfitting” for human and hence a negative option as a mode of daily transportation. Even so, contradictory to this statement, motorcycle as a mode of transportation is becoming even more popular in Asia. The objective of this study is to show that the aforementioned “unfitting” value of the motorcycling working posture is a must in motorcycling. The significance of this study is to share a new perspective in ergonomics. Three studies were conducted: First, a descriptive within-subject design research of real world motorcycling experience using participant observation method. Second, an ethnographic controlled observation to support the findings. Third, an intrinsic case study on motorcyclists who experienced comfort related issues. Results showed that motorcyclists are relatively satisfied with the riding posture since it makes it possible for them to perform the motorcycling work tasks efficiently, thus, ensuring their safety. A too comfortable riding posture actually results in the deficit of the motorcyclist’s riding performance. In short, motorcycling requires a certain level of “discomfort” in order to ensure safely.
Taking Over Control from Highly Automated Vehicles
Authors: Gold Christian , Bengler Klaus
Published: February 2022

Future cars will be able to execute the longitudinal and lateral control and other subtasks of driving. Automation effects, known in other domains like aviation, rail traffic or manufacturing, will emerge in road transportation with consequences hard to predict from the present point of view. This paper discusses the current state of automation research in road traffic, concerning the take-over at system limits. Measurements like the take-over time and the maximum accelerations are suggested and substantiated with data from different experiments and literature. Furthermore, the procedure of such take-over situations is defined in a generic way. Based on studies and experience, advice is given concerning methods and lessons learned in designing and conducting take-over studies in driving simulation. This includes the test and scenario design and which dependent variables to use as metrics. Detailed information is given on how to generate proper control conditions by driving manually without automation. Core themes like how to keep situation presentation constant even for manual drivers and which measures to use to compare a take-over to manual driving are addressed. Finally, a prospect is given on further needs for research and limitations of current known studies.

Published: February 2022

Understanding travelers’ experiences across the whole journey lifecycle is becoming increasingly important for defining and optimizing mobility for all travelers (active travelers and those using public and/or private modes of transport), for transport operators, transport authorities, municipalities and the designers of transport technology. Integrated transport solutions will see greater amalgamation of journey planners, route navigation systems and advanced parking and payment applications, through to vehicle prioritization. The FP7 project, METPEX aims to create a suite of measurement instruments which will capture in real time or retrospectively the whole journey experience, from planning to arrival at destination, across different transport modes. The paper will firstly outline the human factors of each stage of the traveler’s journey. Secondly, it will review the approaches currently used by transport operators to measuring the quality of the passenger experience. Thirdly, the aims and objectives of the METPEX project will be discussed together with work undertaken in the first year of the project, in relation to the development and validation of an extensive set of variables.
Key Players and Their Interactions Within the Young Driver Road Safety System: Perspectives and Partners
Authors: Scott-Parkera Bridie , Salmona Paul , Goodea Natassia , Senserrickb Teresa
Published: February 2022

Young driver road safety has persisted as a global problem for over 50 years, despite a plethora of intervention. Interventions have emerged from a driver-centric approach, and as such predominantly focus upon “fixing-the-driver”. An alternative approach with traction in other safety critical, high risk, domains is systems thinking, which recognises there are a multitude of influential actors (eg, government agencies, community groups) within the broader road safety system that influence young driver safety. Premised on a description of the young driver road safety system (YDRSS) that describes the actors across six levels, interviews were held with 42 actors important in young driver road safety. Synthesis of semi-structured interview transcripts revealed some horizontal integration (interaction amongst actors in the same level) and limited vertical integration (interaction between actors in lower and higher levels), suggesting the current YDRSS is ineffective. A systems approach integrating findings from the driver-centric approach whilst deepening understandings of the complex web of interrelationships amongst actors offers a unique solution to a complex problem. Thus the interviews have revealed avenues of intervention in the YDRSS that can lead to improvements in their road safety and in the road safety of all who share the road with them.
Experimental Studies on Driver’s Expectations Regarding the Positions of Display and Control Elements in the Car Cockpit
Authors: Schwalk Matti , Hetzinger Stephan , Maier Thomas
Published: February 2022

The number of functions within the car cockpit is increasing continuously independent from the class of vehicle. The driver’s cognitive resources are mainly occupied by the traffic, while there are several other possible tasks which can be diverting. Driver’s tasks include tasks of controlling the vehicle, checking relevant display information, adjusting navigation or infotainment systems etc. Despite these sources of diversion in safety relevant situations the driver must be able to find crucial display and control elements immediately and without confusion to avoid an accident. In these situations the driver is using evolutionary developed patterns of behaviour which are activated unconsciously and differing from learned system knowledge. The present work is meant to reveal driver’s expectations regarding the positions of relevant interface elements in the car cockpit. Results are concluded on the basis of a standardised cockpit to give independent design recommendations. The effects and relevance of intuitively expected positions in comparison to unfavourable positions of different interface elements are verified by reaction time measurements.

Authors: kumar Renganayagalu a Sashidharan Komandur Robert Rylander Sathiya
Published: February 2022

The purpose of the present study was to explore the utility of eye tracking technology as a feedback tool in maritime simulator training to assess the trainee performance and to provide more valuable feedback for enhancing trainee-trainer experience. In maritime domain, advanced simulators are used to prepare students for extremely demanding and safety critical operations. However, very little study has been done to develop tools to improve learning as well as measure the learning outcomes. Current training assessment methods are mostly subjective and mainly rely on instructor’s verbal feedback. This paper researches new training method based on eye tracking technology for simulator training, and discusses their application to offshore maritime training. Dynamic positioning (DP) training has been chosen for this study since it is a mandatory system to have installed onboard all modern offshore vessels. A study was conducted with 10 first year nautical students to evaluate this new training method. An assessment checklist for the training outcome was developed based on best practices compliant with NWEA guidelines and used to quantify the student’s performance and to contrast the effectiveness of the new training method with the older one. Results from the study suggest that instructors were able to follow students more closely and were 43% more accurate in assessing their performance in simulator when eye trackers were used. Also using eye tracker, instructors managed to point out some bad practices of students such as too much attention on DP GUIs, which was otherwise not possible to monitor.
Affective States and Driving Behavior of Novice and Young Drivers
Authors: Oehl Michael , Höger Rainer
Published: February 2022

Although general car safety has increased considerably and at the same time accident numbers have decreased remarkably on average in the European Union during the last years, the percentage of novice and young car drivers involved in heavy car accidents is still remaining dramatically high, e.g., in Germany more than twice as high compared to older and more experienced drivers based on their proportion of the driving population. Traffic psychological research shows that maladjusted driving behavior caused by affective states is a main contributor to traffic accidents. Therefore, our current experimental study analyzes this influence of affective states on driving performance with regard to novice and young drivers. In an experimental scenario affective states (positive vs. negative valence) were induced in participants and subjects were then asked to drive predefined routes in a driving simulator. Results indicated that drivers drove significantly faster in a positive affective state compared with drivers in a negative affective state. This effect was pronounced by trend for novice drivers.
Fashion Design and Garment Performance: Human Factors in Fashion Design Projects
Authors: Montagna Gianni , Morais Carla
Published: February 2022

The fashion design project is a multifaceted process that involves several levels and multiple choices. During the design process, the fashion designer creates a fashion concept starting from a user’s needs and fashion styling, evolving to a concrete creation of outlooks and garments that will be proposed to a specific market. Working from general considerations to specific and particular characteristics, any fashion methodology applied by the designer, in order to achieve its goals, has the need to identify and characterize the final consumer and its necessities in terms of garment performance requirements. Due to a high number of human factors involved into the consumer characterization, the identification of the consumer’s performance needs are sometimes difficult to achieve, letting fashion design project far from the real consumers’ needs and market preferences. The multi-dimensional attitude demands nowadays fashion designers for a change to a holistic perception about consumer needs, product design and market characteristics, requiring supplementary fashion design features analysis. The main objective of this paper is an introduction to human factors in fashion design, beginning with the need to confront the perception of fashion clothing by consumers and designers.
Hand Tools: A Study of the Perception of Domestic Users and Woodwork Professionals
Authors: da Silva Falcão Franciane , Correa Pinheiro Leonardo , Macedo da Silva Guilherme , Carlos Paschoarelli Luis
Published: February 2022

The use of some hand tools, utilized within the process of manufacturing wood products, is already popular in the activities of maintenance and setup in domestic environments, which creates groups of users with distinct repertoires, as well as differentiated frequency and kinds of use, with equal mastery of judgment and shopping decision. In the moment of the decision process leading to acquisition, the visual sensorial modality is the most important one. And, sometimes, information about such tools is acquired in catalogs, virtual shops and packages that provide interaction exclusively at the visual level. In order to know the perception of users about some hand tools, parting from visual interaction with them, subjective opinions were collected through: inquisition about the process and criteria on selecting tools, semantic differential tests and evaluation of the perception of comfort through the pair comparison method. Among the results obtained we can highlight that: the aspect “safety” is considered by both user groups as the most important in the moment of selecting the tool; and some users, both domestic and woodwork professionals, relate tool handling with difficulty of use and discomfort.
The Analysis of the Floor-Sitting Behavior Within the Context of Ergonomics Science Elements for the Development of the Floor-Sitting Furniture Design
Authors: M.Najiba Sani. , B.Saifulb Yusoff.
Published: February 2022

This paper presents an analysis of the floor-sitting behavior within the ergonomics’ science context for the development of the floor-sitting furniture design. This study was conducted by observing the floor-sitting behaviors using the video surveillance method within the perimeters of a home environment. The floor-sitting furniture prototype was used as the auxiliary tool to manifest the dwellers’ postural dynamics. Data collection was used over a 6-month period in order to identify the frequency of floor-sitting postures, based on the synthesis of ergonomics science elements. These include: physics, psychology, anatomy, physiology, and engineering, which are mellifluously articulated within the ergonomics’ ergosystems. The prototype of floor-sitting furniture contemporaneously exhibits the significant context of objects used as perching mechanisms; where through this engagement to floor-sitting expressions, the dwellers form another dimension to the sitting comfort definition. This study has successfully produced a detailed illustration of the floor-sitting postures which are idyllically practiced by Malaysians within their home environments. The majority of houses used in this study were fully furnished. However, it was identified that the majority of Malaysians in this study typically preferred sitting on the floor with their bodies perched against objects used for resting. A compilation of floor-sitting data was obtained, and the designed prototype demonstrates the capability of the culturally linked subject’s extension within the explication of the ergonomics, and creative design contexts.

Published: February 2022

This study presents a literature review and a comparison of selected hand anthropometric studies of many populations. The main purpose of this study is to determine the measurements and variables that need to be included in a study of hand for Portuguese population. The comparison and review were performed with studies selected from publications that were found in a literature search performed on Scopus and Google Scholar databases. The considered studies have an evident consideration for the design of hand tools and hand-held devices in the aims of the study and report data collected later than 1990. The review was performed by identifying the measurement included in each study and by comparing their aims and methods. Each study involved a different number of hand measures. Each study had their own reasons for the selection of the hand anthropometric measures involved. However, it can be generally concluded that the studies selected the measures based on a few criteria. The included studies involved a range of 8 to 51 different hand dimensions. The hand dimensions that were considered in at least five different studies were identified.

Published: February 2022

This paper introduces the advantages and disadvantages of the use of digital and physical mock-ups (DMUs, PMUs) in the evaluation of human factors/ergonomics (HFE) in machine cab design. In order to gather information, participatory design, contextual inquiry, observation and interviews were applied in the studies. The main result of the studies was that there is a need for both types of mock-ups when evaluating HFE and validating user requirements. The context of the use is better delivered in DMUs due to the visualisation of the environment and ability to perform the real task. However, depending of the technical set up of the DMU, some deficiency of sensor feedback (etc. haptic) can negatively affect the user’s behaviour. Advantages in PMUs are that they are typically more realistic and provide a better immediate understanding of the cab space. One disadvantage is that often the physical environment around the PMU is not natural enough. It is important to know when, why and how to use different type of mock-ups so as to gain faster time-to-market and better HFE.

Nowadays, the significance of personal hygiene considering is inevitable for all. Axilla perspiration is the factor that causes some problems in terms of hygiene. The study's effort is the implicit film could lie on the body directly and invisibly. Data gathering was developed based on sampling, in depth observation, interviews, questioning and experimental studies. The anthropometic variables of samples` armpits were measured. Undoubtedly in this case the selection of related material has a critical role. Our findings were categorized into three parts of anthropometrics, questionings, and experimental. The related percentages were calculated on the anthropometry dimensions. A significant relationship was acquired between samples' feelings and perspiration level, also between peoples' inconveniences and the amount of sweating. Among the exiting materials, the hydrogels have high water absorption. Hydrogels based on partially hydrolyzed polyacrylamide were used in this case because of several advantages. Sodium Alginate is also used as a substrate for our gel,, which can link to it and have appropriate mechanical properties to hold it during usage. On the basis of the outcomes, the use of antiperspirant films in a way which doesn’t have effects on naturally sweating of body could help control the inconveniences.

Published: February 2022

Many activities of daily living, such as picking up glasses, controlling the house environment, typing text … can become insurmountable for people who have upper extremity disabilities. The alternative to ask for human help is to use some assistive technologies (AT) to compensate for their motor impairment. There are a lot of available AT responding to these needs. However, there are two limitations. The current devices force the handicapped person to use different ATone for each activity and to acquire another AT if his/her impairment changes. The SoKeyTo platform is an environment which offers functions to design virtual interfaces (robotic arm, home control and virtual keyboard for text input). We analyzed and compared SoKeyTo and other toolkits. The SoKeyTo platform offers configuration options for the interaction techniques, the design of buttons according to the needs and the abilities of the user and the multimodal feedback linked to these buttons. We describe the characteristics of two interactive interfaces designed with SoKeyTo. We report results from a utility and usability questionnaire from trials conducted with two representative end users. The questionnaire also showed a strong interest of the SoKeyTo tool.

The study was undertaken aiming to study the effect of age on carcass traits and meat quality of Barind sheep of Bangladesh. Ninety six male lambs were reared by 16 farmers at two upazila namely Paba and Godagari in Rajshahi district. Lambs were slaughtered at 6 (T1 ), 9 (T2 ) and 12 (T3 ) month‘s age. Each farmer kept 6 lambs (Two lambs for each 3 age category). Four types dressing percentages were measured; DRSWIEO (on the basis of slaughter weight and hot carcass weight including edible offal), DRSWEXEO (on the basis of slaughter weight and hot carcass weight excluding edible offal), DREMIEO (On the basis of empty body weight and hot carcass weight including edible offal) and DREMIEO (On the basis of empty body weight and hot carcass weight excluding edible offal). All lambs received maternal milk and a supplementation of commercial concentrate @ of 1.5% of live weight up to slaughter and allowed to graze for 8 hours a day on natural grassland. The Redness (a) was more (18.80±0.06) in 12 month‘s lamb and Yellowness (b) was higher (10.17±0.06) in 6 month‘s lamb. Ultimate pH (pHu ) varied significantly among age groups and it was lowest (5.62±0.01) at 6 month and highest at 9 month. Drip loss (DL) was highest on young and lowest in aged lambs. Dry matter (DM) and Crude protein (CP) both were varied significantly (p<0.05) in age groups showing highest DM (27.64±0.06%) and CP (23.61±0.03%) in young (6 month of age) lambs for both attributes. Minerals (Ash) was highest (0.89±0.06%) in aged (12 month of age) group and lowest (0.78±0.01) in young (6 month of age) and it was differed significantly (p<0.01) among treatments. Cooking loss (CL) and Ether extract (EE) were not differed (p>0.05) among treatments. The panel of examiners was attracted more to the color of aged lambs (12 month of age) and acquiring number (4.43±0.03) was varied significantly (p<0.01) among ages. Flavor was varied significantly (p<0.05) among ages tended to secure more point for 9 month lambs. Overall acceptability was differed significantly (p<.01) among ages and meat of 9 month lamb showed highest (4.57±0.03) acceptance.

Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disease characterized by a wide spectrum of clinical manifestations with varying severity. The dysregulation of cytokines contributes strongly to disease pathogenesis. Recently, it has been shown that the imbalanced antagonist/agonist profile of interleukin (IL)-36 cytokines, might play a role in autoimmune disorders. Our aim is to investigate mRNA expression of Interleukin-36α (IL-36α) in the peripheral blood of Egyptian systemic lupus erythematosus (SLE) patients and its association with disease activity and organs involvement. We assessed the relative expression of IL-36α mRNA by real time polymerase chain reaction and the comparative CT method on the peripheral blood of 49 SLE patients, and 40 healthy controls. Patients were subjected to thorough history and clinical examination, in addition to routine hematological, biochemical, and serological studies. Disease activity was evaluated using the SLE Disease Activity Index (SLEDAI). The relative expression of IL-36α mRNA was significantly higher in SLE patients compared to healthy controls (4.3±2.9 vs 1, respectively, P<0.0001). Fold change of IL-36α expression was significantly increased in patients with moderate and high disease activity (SLEDAI>5) than patients with mild disease activity (SLEDAI≤5) (4.3±1.2 vs 2.7±2.0, respectively, P=0.006) and positively correlated with SLEDAI (r=0.505, P=0.001). Regarding major organ involvement, the mean±SD expression of IL-36α in patients with arthritis and mucocutaneous involvement was significantly higher compared to those without organ involvement (4.2±1.5 vs 2.8±1.8, P=0.039 and 4.1±1.4 vs 2.8±2.1, P=0.041, respectively). In conclusion, the IL-36α is significantly more expressed in SLE patients compared to healthy controls and correlated with SLE disease activity and arthritis. IL-36α expression could be a useful biomarker for SLE disease activity in Egyptian patients with SLE.

Garbage is a classic and unsolved problem in Indonesia. According to data from the Ministry of Environment and Forestry (KLHK), Indonesia's amount of waste reaches 67.8 million tons consisting of 57% organic, 15% plastic, 11% paper, and 17 other waste. However, a garbage bank has established, even though its role still minimal compared to the City Waste Power Electric (PLTSa). By using ANP (Analytic Network Process) this qualitatively descriptive paper shows that the essential aspects from PLTSa are Institution and community. The problem of PLTSa is divided into three aspects such as expensive, 3T, and environment. In this case Waqf institutions such as education, socialization and cost. The issues of society are literacy, habits, lazy. Mapping solutions, in-depth studies, collaborations, webinars. Strategies in improving the environment security, among others, are the synergy of waqf institutions with the government, BOT system between Waqf Institutions and private businesses, and the last collaboration between waqf institutions and waste banks.

SOME FEATURES OF THE VULNERABILITY FUNCTION AND THEIR USE FOR SEISMIC RISK ASSESSMENT
Authors: Уздин А.М. , Богданова М.А. , Линг Х.
Published: February 2022

Отмечаются некоторые особенности функций уязвимости. В частности, функции уязвимости обладают всеми свойствами функции вероятности. Это позволяет ввести в функции уязвимости такие характеристики как аналог функции плотности вероятности, математическое ожидание и дисперсию. Аналог функции плотности вероятности характеризует скорость накопления поврежде­ний в системе. Математическое ожидание определяет среднее значение опасной нагрузки. А дисперсия определяет волатильность функции уязвимости. Сказанное позволяет использовать для аппроксимации функции уязвимости известные функции распределения вероятностей. В частности, закон Вейбула. В работе показано как оценить сейсмический риск, используя только дисперсию и среднее значение функций уязвимости. Получены простые формулы для оценки риска и проведено их сопоставление с точными вычислениями.

Проанализированы основные положения актуализированной редакции нового нормативного документа — СП 15.13330.2020 «СНиП II- 22-81* Каменные и армокаменные конструкции» — в части методики оценки и принятых значений коэффициента надежности камен­ной кладки с учетом ее материала (кирпич, камень и ячеистобетонные блоки) и вида ее напряженного состояния (сжатие, растяжение при изгибе и срезе по перевязанному и неперевязанному сечениям). Отмечено, что принятые подходы о назначении коэффициента надеж­ности в новых нормах не являются научно обоснованными. Приведенные завышенные значения коэффициентов надежности не обеспечи­вают безаварийную работу конструкции. Указано, что цель любого нормативного документа — не достижение максимальных запасов прочности конструкции, а нахождение оптимального компромисса между суммарными затратами и надежностью. Коэффициенты за­паса прочности должны основываться на научных исследованиях и быть экономически оправданными. Отмечено, что данному условию соответствует вероятностный подход к оценке прочностных характеристик элементов кладки с переходом от марок материалов к классам. Проанализированы данные по величинам коэффициента надежности, принятые в нормах и указаны отдельные неточности в назначении этих коэффициентов, которые приняты волевым способом и не отвечают реальному положению дел. На основе проведен­ного анализа исследований в области надежности конструкций показано, что переход на вероятностное нормирование прочностных свойств раствора и кирпича и кладки в целом с использованием классов позволит существенно повысить надежность и безаварийность возводимых кирпичных конструкций. Рассмотрены пути решения проблемы повышения надежности каменных конструкций в случае применения вероятностных методов при назначении прочностных характеристик элементов каменной кладки.

В статье описывается применение сейсмологического метода регистрации микросейсм для решения технических задач, в частности, обследования жилых многоквартирных домов. Целью исследования ставится обнаружение возможных скрытых нарушений несущих конструкций при обследовании состояния значительного количества зданий г. Катав-Ивановск Челябинской области после недавне­го сейсмического события в сентябре 2018 г. Описаны примеры использования микросейсмических колебаний при анализе состояния многоэтажных строений в нескольких работах российских и зарубежных авторов. Оценка объектов проводилась по нескольким дина­мическим характеристикам, таким как частота собственных колебаний, логарифмический декремент затухания и максимальная скорость смещения конструкции в точке измерения. С целью масштабирования стандартного метода обследования строительных объектов и оперативности процесса, авторами было предложено уменьшить длительность записи микросейсм, инструментальная поддержка экспериментальной части реализована с использованием трехканального регистратора сейсмических сигналов и велоси- метра отечественной разработки. Результаты наблюдений и измерений сопоставлены с нормативными величинами, приведены и систематизированы значения динамических характеристик для домов различных типов.

В статье проведено механико-математическое моделирование селективного водозаборного процесса в двухслойном стратифици­рованном водоеме, когда вода забирается из верхнего осветленного слоя водоема для нужд технического водоснабжения некоторого промышленного предприятия. Составленная модель представляет контактную начально-краевую задачу теории поверхностных и внутренних гравитационных волн в идеальной несжимаемой жидкости. В результате аналитического решения поставленной на­чально-краевой задачи получена совокупность расчетных формул, которая с привлечением компьютерных вычислительных средств позволяет рассчитать и выбрать габаритные размеры водозаборного окна, а также величину его заглубления в воде с тем расчетом, чтобы обеспечивался селективный водозаборный процесс исключительно из верхнего осветленного слоя водоема и чтобы вода из ниж­него мутного слоя не затекала в водозаборное окно. Выбор указанных входных параметров системы стратифицированный водоем - водозаборное окно обеспечивает устойчивый селективный водоотбор исключительно из верхнего осветленного слоя водоема.

The Role of Consumers’ Individual Differences and Perceived Product Quality in Sustainable Luxury Marketing: An Experimental Study in a Social Media Context
Authors: Colella Giuseppe , Sestino Andrea , Amatulli Cesare
Published: February 2022

Sustainability has become a central issue for luxury marketers and managers. By considering the luxury sector, consumers are more interested in buying sustainable products. However, luxury brands need to find the right way to communicate their sustainable products, especially in the online context. This paper sheds light on the differentiated effect of a luxury product communication message focused on an internalized versus externalized luxury approach in social media platforms context. Internalized luxury refers to luxury consumption mainly driven by individual style, while externalized luxury consumption refers to luxury consumption mainly driven by status. Results show that a sustainable luxury product communication focused on internalized (vs. externalized) luxury activates a greater perception of product quality, which in turn leads to a greater intention to buy. Theoretical contributions and implications for luxury brand managers are discussed.

The BeSS Mansion Sarabaya apartment building is a construction project with a total building area of 86,000 m2. This apartment complex, which is located in the centre of Surabaya, includes 44 stories of Tower Premiere, 42 stories of Tower Suite, and 9 stories of Tower Podium parking area. Tower Cranes are used to transport or move materials in the construction of high-rise buildings. The objective of this thesis analysis is to figure out how many Tower Cranes are needed, as well as scheduling, operational costs, site layout, traffic management, and the HIRARC matrix. The data used were shop drawings, Tower crane specifications, and Tower Crane rental prices. According to the results of this calculating plan, two units of Tower Cranes are required to complete structural work, with a total work time of 5,592 hours. Tower Crane type MCT 205 requires a rental cost of Rp. 844,266,37 per hour, whereas Tower Crane type Tengda TC 6018 requires a rental charge of Rp. 701.184.89 per hour. On the site layout study, there are four options, and option 2 has been chosen because it is close to 0 or the minimum value, and traffic management planning uses an one gate system.
