Special Issue on Developments and Learning from the World Robot Challenge
Authors: Venture Gentiane 
Published: February 2023

The World Robot Challenge was organized to stimulate and gather findings in robotics and their applications to three important fields: Industrial Robotics, Service Robotics, and Disaster Robotics, which constituted three categories for the competition. Researchers and professionals from all over the world in the field of robotics were provided a unique opportunity to showcase their work by solving unprecedented problems, on the spot. Computer vision, robust control, navigation, and manipulation are some of the key elements to create robots that could solve the challenges proposed during the competition.
This special issue provides some examples of the work developed and performed in that aim, that could serve for the future of robotics applications in the three designated fields but not only.
The three first papers are the results of the convenience store challenge for Service Robotics. In this challenge, identifying objects and pose estimation of object are crucial for the acquisition of knowledge and robot manipulation, shelfing and logistics, as detailed in the first two papers. Robot’s navigation is also paramount for cleaning and operating in the human environment, such is the topic of the third paper.
The Industrial Robotics challenge focuses on parts pick and place and assembly of complex elements. The fourth and 5th papers of this special issue deal with this topic.
Finally the Disaster Robotics challenge presents the more versatile components as a disaster area may be of multiform and of very complex nature, depending of the nature of the disaster, whether it is indoor or outdoor etc. The last three papers of the special issue deal with such a various nature for plant inspection, for the control of robots in disaster area, or the rescue robot in confined spaces such as tunnels.
We hope this collection of work carefully selected, will provide the reader with insights for the future developments of robots.
The role of victimisation and sleep quality in self-harm and depression among sexual minority adolescents. A prospective cohort study.
Authors: TEPMAN Alexandra , WONG Mark Lawrence 
Published: February 2023

Abstract

Sexual minority adolescents (SMA) have a disproportionately high prevalence of victimisation, self-harm and depressed mood, compared to the general population, while the contributing and mechanistic factors are unclear. We aim to explore the directional relationship between victimisation and self-harm and depressed mood, with poor sleep quality as a possible mediator. A secondary data analysis was conducted using a nationally representative birth cohort in the United Kingdom, where participants self-identified as sexual minority (N=1922, aged 11-13, 67.1% female) and their parents completed questionnaires and interviews when the participants were aged 11, 14 and 17. Logistic and linear regression were used to test whether victimisation prospectively predicted self-harm and depressed mood with mediation analyses conducted to assess if sleep onset latency and nocturnal awakening mediated their relationships. After adjusting for demographic factors and baseline self-harm and depressed mood, victimisation at age 11 significantly predicted self-harm (OR=1.40, p<.01) and depressed mood (B=.024, SE= .01, p<.05) at age 17. In the mediation analyses, frequent nocturnal awakening at age 14, but not sleep onset latency, significantly mediated the effect of victimisation at age 11 on self-harm (indirect effect B=.008, SE=.004, 95%CI=.001-.017) and depressed mood (indirect effect B=.005, SE=.002 95%CI=.001-.010) at age 17. Our findings supported that victimisation contributed to negative mental health among SMA. Poor sleep quality could be an indicator of maladjustment with victimisation, which further increased vulnerability to negative mental health. Victimisation and sleep quality could be important assessment targets in mental health campaign among sexual minority adolescents.

Несмотря на неэффективность «универсальной» модели лесного хозяйства, результатом которой является истощение доступных лесных ресурсов для лесной промышленности, завышение в 2-3 раза расчетной лесосеки в ряде лесопромышленных регионов, уменьшение площади и доли в насаждениях твердолиственных пород и кедровых сосен, а также возрастание темпов утраты малонарушенных массивов первичных лесов, органы управления лесным хозяйством России стремятся сохранять традиционное экстенсивное лесное хозяйство. Профильные ведомства, вопреки принятым в 2013–2018 гг., стратегическим документам по развитию лесного комплекса, не стимулируют на практике переход к интенсивному лесному хозяйству. Последнее требует брать арендную плату за единицу площади аренды; переход лесопользования на рубки по «диаметру» зрелостии т.п. Переход от экстенсивной модели на модель интенсивного использования и восстановления лесов экономически выгоден в регионах с более высокой биопродуктивностью лесных земель, с большей плотностью лесных дорог и развитой инфраструктурой. Представляется актуальной задача пространственной де-маргинализации лесного комплекса страны – сдвиг лесосырьевой базы и инфраструктуры переработки из северной тайги ЕТС и Средней и Восточной Сибири во вторичные леса зоны хвойно-широколиственных и южно-таежных лесов ЕТС с достаточно развитой и более густой дорожной сетью.
Inefficiency of the «universal» traditional forestry model, which results in depletion of available forest resources for forestry industry, an overestimation of allowable cut in forestry regions by 2-3 times, and a decrease in area and share the most valuable and ecologically significant hardwoods and cedar pines, as well as an increase in the rate of intact primary forests loss. . The departments in charge, contrary to strategic governmental documents adopted in 2013–2018, do not take steps to stimulate transition to an intensive forestry model, which requires to charge fees based on a unit of leased area, and not the volume of cut wood; the transition of forest management to felling based on tree diameter instead on the tree age, etc. It is obvious that the transition to a model of intensive use and restoration of forests is more economically beneficial in regions with higher biological productivity of forest lands, with a greater density of forest roads and more developed infrastructure. The problem of spatial demarginalization of the country's forest complex seems to be an urgent task – the shift of forest resource base and processing infrastructure from the northern taiga of European Russia (ER) and Central and Eastern Siberia to secondary forests of coniferous-broad-leaved and southern taiga forests in ER with a developed and denser road network (6-7 km per 1000 ha and above). This position is confirmed by growth of investments in timber processing and production of wood-based panels, sheet materials, etc. by private companies.

Исследование посвящено анализу основных технических характеристик колесных узкозахватных валочно-пакетирующих машин фронтального типа методами стохастического математического моделирования. Проанализированы были следующие параметры: мощность двигателя, масса машин, давление на грунт, энергонасыщенность, максимальный диаметр срезаемых деревьев и масса захватно-срезающих устройств. В результате статической обработки с применением программного обеспечения Statgraphics 18 были получены законы распределения каждого из исследуемых параметров. Также был проведен однофакторный и многофакторный регрессионный анализ. В результате однофакторного регрессионного анализа были получены зависимости мощности двигателя, давления на грунт и массы машины от максимально возможного диаметра срезаемых деревьев. Двухфакторный регрессионный анализ позволил получить зависимости: мощности двигателя от максимального диаметра срезаемых деревьев и массы машины; массы машины от максимального диаметра срезаемых деревьев и мощности двигателя; давления на грунт от максимального диаметра срезаемых деревьев и мощности двигателя. Полученные регрессионные зависимости позволяют приближенно определить значения величин мощности, массы машины и давления на грунт, как на стадии конструкторской разработки, так и при выборе машины для эксплуатации в зависимости от требований к диаметру срезаемых деревьев.

Экспериментальным и расчетным путем определена рациональная аэродинамическая обстановка в топке пылеугольного котлоагрегата при различной ориентации в пространстве камеры потоков горячего воздуха из узла подачи заднего дутья. Численное моделирование процессов гидродинамики и тепломассообмена в топочном пространстве теплотехнологического устройства выполнено с помощью современного вычислительного комплекса PHOENICS. Показана возможность управления неравномерностью потоков энергоносителя в рабочей камере конкретного котлоагрегата, а значит и эффективными режимами его работы. Полученные как опытные, так и расчетные данные позволили определить не только оптимальные пространственные рабочие параметры узла подачи заднего дутья и расходные характеристики для двух типов горелок, но и получить набор рациональных параметров узла заднего дутья при изменении режима работы котлоагрегата, например, при плановых снижениях его нагрузки. Использование результатов исследований позволило практически исключить аварийные ситуации вследствие не эффективной работы воздушных завес заднего дутья.
The rational aerodynamic situation in the furnace of a pulverized coal boiler was determined experimentally and by calculation at different orientations in the space of the chamber of hot air flows from the rear blast supply unit. Numerical modeling of the processes of hydrodynamics and heat and mass transfer in the furnace space of a heat-technological device was performed using the modern PHOENICS computer complex. The possibility of controlling the non-uniformity of energy carrier flows in the working chamber of a particular boiler unit, and hence the effective modes of its operation, is shown. Both experimental and calculated data obtained made it possible to determine not only the optimal spatial operating parameters of the rear blast supply unit and flow characteristics for two types of burners, but also to obtain a set of rational parameters of the rear blast unit when changing the operating mode of the boiler unit, for example, when new reductions in its load. The use of research results made it possible to practically eliminate emergency situations due to inefficient operation of the rear air curtains.

Оценка всех совокупных свойств сосны чёрной, как вида важна не только в целом, но и для ее разновидностей из изолированных популяций. Ассортимент достаточно устойчивых и декоративных видов сосен в регионе европейской части Российской Федерации оказывается весьма ограниченным, но в нем отведено место сосне черной австрийской. Отсюда цель исследования - рассмотреть особенности роста и состояния сосны черной австрийской в условиях интродукции на территории лесостепного района европейской части Российской Федерации (Воронежская область). По отношению к различным заболеваниям ее следует отнести к весьма устойчивой породе, подтверждением чего является соответствующая категория санитарного состояния на объекте – I,1. Расчеты показывают, что сосна черная австрийская на плодородной почве по запасу древесины превосходит сосну обыкновенную в характерных условиях последней. В результате дифференциации пород по декоративным признакам следует отдать первенство сосне черной (24 балла) с незначительным перевесом над сосной обыкновенной (20 баллов). С учетом полученных данных можно рекомендовать в условиях зеленого строительства куртинное размещение породы по три дерева на посадочное место с расстоянием между деревьями в куртине до 2,5 м, а между самими куртинами – 5 м.
Assessment of all aggregate properties of black pine as a species is important not only in general, but also for its varieties from isolated populations. The assortment of fairly stable and ornamental pine species in the region of the European part of the Russian Federation turns out to be very limited, but a place in it is given to Austrian black pine. Hence, the purpose of the study is to consider the features of the growth and condition of the Austrian black pine in the conditions of introduction in the foreststeppe region of the European part of the Russian Federation (Voronezh region). In relation to various diseases, it should be attributed to a very resistant species, which is confirmed by the corresponding category of sanitary condition at the site – I,1. Calculations show that the Austrian black pine on fertile soil surpasses the common pine in the characteristic conditions of the latter. As a result of differentiation of species by decorative features, we should give priority to black pine (24 points) with a slight preponderance over Scots pine (20 points). Taking into account the data obtained, we can recommend in terms of green building the location of the species in a cluster of three trees per planting place with a distance between trees in the cluster to 2.5 m, and between the clumps themselves – 5 m.

Johne's disease (JD) is caused by Mycobacterium avium spp paratuberculosis (MAP). It is an incurable, chronic inflammation of the gastrointestinal tract of cattle that causes diarrhea, weight loss, and reduced production. Commonly recognized risk factors for MAP transmission include purchase of subclinically infected cows and the infection of calves through ingestion of manure, colostrum or milk containing MAP shed by infected cattle. To limit the negative effects of JD on the dairy industry in Ontario, Canada, the voluntary Ontario Johne's Education and Management Assistance Program (OJEMAP) was implemented in January 2010. Producers can participate in MAP antibody ELISA testing and an on-farm risk assessment and management plan (RAMP) with their herd veterinarian. High RAMP scores are associated with high risk for MAP transmission.
Organic farming is one of the fastest growing agricultural sectors worldwide. In Ontario, approximately 80 dairy farms (2% of all dairy farms) are certified organic. While most organic farmers tend to maintain closed herds, which would reduce the risk for JD introduction, they also often support prolonged contact between newborn calves and their dams. These and other factors could potentially influence the risk of MAP transmission as well as JD prevalence and prevention efforts on organic dairy farms. The aim of this cross-sectional study was to assess the Johne's ELISA prevalence and Johne's disease transmission risk on organic dairy farms in Ontario.

Published: February 2023

Background:
The Internet of Things (IoT) is an embryonic model that converts realworld
things (objects) into smarter devices. IoT is applicable to a variety of application domains,
including healthcare, smart grid, and agriculture. Low Power Wide Area Network (LPWAN) technology
can transmit data over long distances with a low data rate without using the internet. Therefore,
this technology is suitable for sending sensor measurement data in Internet of Things (IoT)
applications. LPWANs, such as LoRa, use a star topology to reach their coverage to the maximum
power that can be transmitted, considering the environmental conditions in the test area and the
LoRa parameters used. Whereas for application development in rural areas, there is no internet
connection, and often longer coverage is required from the sensor node to the gateway.

Objective:
This study aims to increase the transmission range from the end node to the gateway by
adding an intermediate node. It is used as a relay from the end node to the gateway.

Method:
Static routing was applied so that any broadcast data from the end node would be forwarded
first to the intermediate node and then to the gateway.

Results:
The LoRa transmission range expanded by changing the topology from peer-to-peer to
multi-hop. An intermediate node between the transmitter (end node) and the gateway is available.
In the experiment performed, a multi-hop with static routes successfully expanded the distance
from 150 meters (single hop) to 250 meters (multi-hop), with a packet delivery ratio of 97%. In this
experiment, GPS Ublox Neo was used for the sensor position and was successfully tested on the
end node with an accuracy rate of 2.4% for latitude and 0.2% for longitude.

Conclusion:
The transmission range from the sensor node to the gateway can be extended using
static routing by installing an intermediate node between the gateway and the sensor node. The data
from the end node is successfully received by the gateway.

Published: February 2023

Aims:
To evaluate the environmental benefits of the manufacturing system and optimize
the process parameters, a more effective method of evaluating environmental benefits should be
adopted, which can be used for process parameters optimization.

Background:
Mechanical manufacturing systems generally include raw materials, energy, products,
waste emissions, capital, labor, and other elements. The Extended Carbon-Emissions Accounting
(ECEA) method is an extension of the traditional Carbon Emissions Accounting (CEA) method, which
can account for capital and labor elements in equivalent carbon emissions similar to other elements.

Methods:
Through the ECEA method, the Extended Carbon Dioxide Emissions (Ex-CDE) of the
manufacturing system are obtained by accumulating the value by multiplying the consumption of
each element and its Extended Carbon Emission Factor (Ex-CEF), which can be used as the environmental
benefits of the manufacturing system. Then, a comprehensive optimization case of lowcarbon,
high-efficiency, and low-cost can be built, including all consumption elements, and the
COMPLEX algorithm is used to solve this optimization problem.

Results:
Taking a turning process as an example, through the ECEA method combined with the
COMPLEX algorithm, the process parameters for environmental benefits or comprehensive optimization
can be solved.

Conclusion:
ECEA method is suitable for environmental benefits analysis and optimization of the manufacturing system.

Language is not only used as the means of communication, but also the device of achieving dominance. This article aims at describing and analyzing the real meaning of bharata and revealing misinterpretation on the meaning of bharata by Buton Kingdom for political dominance device on four surrounding kingdoms: Muna, Tiworo, Kaledupa, and Kulisusu in the 17th – 20th centuries. The study was designed descriptive qualitativey with four steps of framework: (1) exploring data, (2) data verification, (3) analysis, and (4) writing results of analysis. Data were analyzed by applying Wodak’s critical discourse analysis approach (CDA). Results of the analysis concluded the real meaning of bharata is “front area and center of battle”. The term of bharata was firstly acquainted by Laki Laponto, the king of Buton at the beginning of 16th century when he organized military alliance by involving the four surrounding kingdoms to face Ternate’s threaten. Since at the beginning of 17th century people of Butonese misinterpreted the meaning of bharata subjectively for political interest. Buton kingdom then established their misinterpretation instituonally and performed hegemony to the four surrounding kingdoms by the assistance of Dutch after welcoming and signing bilateral coalition with Dutch at the beginning of 17th century.
