Analyze the factors influencing human-robot interaction using MCDM method

Robots play a key role in medical equipment manufacturing industry by safeguarding human workers from hazardous environment and risky jobs. Human robot interaction (HRI) is one of the robotic features that are enhanced in industrial robots. They mimic human behavior while arriving at a decision, contributing to the proficiency of the product. Tasks involving human cognitive skills and flexibility in the workers are combined with robots to obtain high-level accuracy, repeatability, and speed. Further, more challenges are to be met for achieving an effective human-robot interaction. In this paper, risk factors affecting the interaction between both robot and humans are discussed, and a contextual case is performed in a top south Indian medical equipment manufacturing industry. Industrial experts' inputs and relevant literature are considered to recognize the risk factors. Multi-Criteria decision-making method (MCDM) like DEMATEL (Decision Making Trial and Evaluation Laboratory) is used to analyze the risk factors influencing HRI in the assembly section. The paper's findings show that automation level and reliability of the robot are the most influential factor in the assembly section and need more attention to control and reduce the risk factor for the effective assembly.

Lagrangian Modeling and Optimal MIMO PID Control of a Manipulator Using Tabu Search Algorithm

Robot manipulators, given their promising features and capabilities, have found a variety of applications in many fields including construction, nuclear, car, manufacturing and surgical industries, among others, which has turned them to a large and diffuse industry. In construction, use of robots has automated many tasks and risky jobs, including multitask road construction and maintenance processes based on ergonomic and economic analyses, surface finishing, concreting, excavating and backfilling, to name but a few. Hence, manipulators have progressively replaced human labor to meet strict health regulations, productivity gains, and control goals. Movement of an effector tool into a proper location and orientation required for a work object is the main role of a manipulator. In this research dynamic modeling and control of a 2-DOF planar robotic manipulator is presented using a PID controller to obtain optimal position of final operator of the manipulator. Considering nonlinearity of the system under consideration, to optimize final position of the manipulator, parameters of PID controller were tuned using Tabu Search (TS) algorithm as one of meta-heuristic optimization techniques. Numerical results obtained from simulations in this study demonstrated robustness and efficiency of the selected approach for optimizing the final position of the manipulator, minimizing oscillations and fast convergence of the error function to zero, compared to that of uncontrolled state as well as controlled system by PID controller with empirically adjusted factors. Efficiency of the proposed method was verified for different angular positions of joints in the manipulator. Keywords:Lagrangian Modeling; Manipulator; MIMO PID Controller; Evolutionary Algorithms

An Integrated Strategy for Data Mining Based on Identifying Important and Contradicting Variables for Breast Cancer Recurrence Research

Cancer leads to most deaths worldwide, and breast cancer isa leading disease that causes death among women. This disease is unique in the way that once treated, can recur in some cases. Individuals are unable to identify their condition before it becomes dangerous. Extracting significant predictive features of breast cancer is an important and risky job for further study. Researchers have applied data mining techniques in medical science. Several authors suggest that a single method doesn't resolve issues in diagnosing problems, and a hybrid model is desirable. In this paper, the authors propose an integrated approachto avoid Type 1 and 2 errors in predicting recurrence. They identify important and contradicting variables and consider them for inclusion and exclusion, respectively, to revise the dataset. The evaluation of findings of crucial methods, using original and revised datasets, widens the choice of identifying the technique with higher accuracy. The results show that the accuracy improves with the selection of variables restricted to the ones identified as relatively significant, and the dataset revised after elimination of contradicting variables.

Reported injury, hospitalization, and injury fatality rates among New Jersey adolescent workers

BackgroundWorkplace injuries are a public health concern, including among adolescents and young adults. Secondary school career-technical-vocational education related injuries are mandated by code under jurisdiction of New Jersey Department of Education to be reported online to New Jersey Safe Schools Program. These are the only U.S. law-based surveillance data for young workers in secondary school career-technical-vocational education. New Jersey Department of Health’s hospitalization and fatality records provide additional information about other secondary school career-technical-vocational education and non- secondary school career-technical-vocational education related injuries not necessarily reported to New Jersey Safe Schools Program. This report compared data available to the New Jersey Department of Health and New Jersey Safe Schools Program on injuries among young workers ages 14–21 years.MethodsAnnual work-related hospitalizations, 2007–2016, were abstracted from hospital discharge data. Denominator data from the U.S. Bureau of Labor Statistics was used to estimate annual crude rate of hospitalizations per 100,000 employed persons. Hospitalization rates were stratified by demographic data from the U.S. Bureau of Labor Statistics. Hospitalization rates for primary diagnoses and job title/status with ≥2 documented cases were reported. Annual crude fatality rates per 100,000 full time equivalent workers, age ≥ 16 years, were estimated for 1990–2016 using annual average full time equivalent workers and the U.S. National Institute Occupational Safety and Health’s Employed Labor Force Query System as denominator.ResultsAnnual crude hospitalization rates decreased over time. Hospitalization and fatality rates were higher among young adult workers ages 19–21 years; non-Hispanic Whites; and, males. Percent fatality for ages 19–21 years was greater than ages 14–17 years and 18 years. Declines in hospitalization rates corresponded to decreases in reported injuries among career-technical-vocational education students. Age distribution varied slightly between hospital discharge data and New Jersey Safe Schools Program data.ConclusionHospitalization and fatality rates were higher among males than among females, possibly reflecting a tendency for males to engage in riskier jobs than females. Understanding injury disparities can inform public health prevention efforts. Trainings/interventions should aim at addressing the most frequently diagnosed conditions or nature of reported injuries, within those most impacted career clusters like sales/restaurant workers.

Legal Protection to Commercial Sex Workers (PSK) Viewed From Reproductive Health Aspects at Pasar Kembang (Sarkem) Yogyakarta

All women had equal rights to reproductive health, no exception for commercial sex workers (PSK), because PSK was a very risky job for various diseases, among others, gonorrhea, herpes, fungal infections, syphilis, vaginitis, ulcers, sex lice, and HIV/AIDS. However, in reality, not all PSKs got their rights to reproductive health. The Government had issued a regulation related to reproductive rights, namely Government Regulation Nr. 61 of 2014 on Reproductive Health. This research used the socio-legal approach with the analytical- descriptive specification. The primary data were obtained from interviews with the Head of Public Health Center (Puskesmas) of Gedongtengen, doctors, midwives, coordinator of commercial sex workers association, AIDS Prevention Commission, the Head of Infectious Disease Control Section of the Health Office of Yogyakarta City, hotel owners and commercial sex workers (PSK). Secondary data were obtained from books and legal materials having relations with the research. The data gathered were then qualitatively analyzed.The results of the research at Puskesmas of Gedongtengen showed that PSK had obtained legal protection by the contents of articles of the prevailing legislation and the Minister of Health’s regulation. Puskesmas of Gedongtengen had reproductive health services programs such as clinical sexual services of sexually transmitted infections (STI) and voluntary counseling and testing (VCT). If by an examination a PSK was found HIV/AIDS positive, she would be referred to a hospital having facilities by her needs. On the one hand, the supporting factors of the implementation of legal protection to commercial sex workers regarding reproductive health included affordable costs of the Puskesmas, availability of competent health personnel, adequate facilities, and infrastructure, cross-sectoral cooperation, PSK involvement in the services provided. On the other hand, the inhibiting factors were the absence of specific legislative regulations on PSK, low-level education that led to lack of health examination awareness, a lot of the customers that refused to use condoms and the insufficient availability of skilled health personnel.

Faktor Risiko Kejadian Leptospirosis Di Wilayah Kabupaten Gresik (Tahun 2017-2018)

Leptospirosis is a disease derived from animals with Leptospira bacteria as the main cause. Leptospirosis can occur if the host / human is in contact with animals infected with Leptospira bacteria. In 2017-2018, leptospirosis occurs in the community in several sub-districts in Gresik Regency. The purpose of this study was to determine what risk factors related to the incidence of leptospirosis in Gresik Regency. This study uses an observational method with case control study design with 14 respondents and 14 controls. Analysis was performed by chi square statistical test (α = 0.05) and odds ratio (OR) calculation. Factors studied were standing water, ditch conditions, flood history, presence of vegetation, use of APD while doing risky work, washing hands and feet with soap and the habit of closing food. The results showed 54.5% of leptspirosis patients aged 46-55 years, 50% were male, and 66.7% had a risky job. There is a relationship between the presence of stagnant water (p = 0.0001 and OR = 22), ditch conditions (p = 0.053 and OR = 0.205), APD use (p = 0.000), and washing feet and hands with soap (p = 0.000 and OR = 0.031) with the incidence of leptospirosis. There was no relationship between the history of flooding, the presence of vegetation, and the habit of closing food with the incidence of leptospirosis. Rats were caught by placing 28 traps and found 9 trapped rats. It was concluded that the factors associated with the incidence of leptospirosis in Gresik Regency were the presence of stagnant water, ditch conditions, APD use, and washing hands and feet with soap.

Banking Law in the Light of Nepalese Supreme Court Verdict

Banking law is the branch of civil law which tries to perpetuate credibility of banking business. Good governance, customer protection, transparency and financial safety are the major concern of banking jurisprudence. In contemporary time, banking business is much risky job across the globe because if there is no proper awareness of existing laws and regulations, it may not only be the threat of the job but also causes huge amount of penalty to secure public confidence and protection of depositors. Efficiency in the fund management is necessary. Nepal doesn’t have long history of banking business. Yet, its scope has been increasing and ever increasing. Supreme Court of Nepal has developed new dimensions of banking jurisprudence for safe and secured transaction of banking business. Cross border banking poses new level of threat, which is necessary to resolve with global cooperation. As a common law following country, precedence of the court is equivalent to the legislation in Nepal until quashed by new decision.

Determinant of Personal Protective Equipment Practices on Construction Welders

The construction sector has been the largest contributor to the occurrence of accidents around the world. One of the production processes in construction at risk of accidents and occupational diseases is welding work. In Indonesia, especially in Surakarta, there are still a number of welders in the construction sector who work without using personal protective equipment (PPE), while the welding work itself is a risky job in terms of health and safety. This paper examines the most influential predisposing factor towards the practice of personal protective equipment application on welders. Predisposing factors studied in this study were age, working hours, level of education, history of work accidents in welding, knowledge and practice in the use of personal protective equipment. Cross sectional study was employed in the study conducted from February to July 2017 in 20 construction site locations in Surakarta, Central Java, Indonesia. Data was collected through face-to-face interviews using a structured questionnaire. The research population consisted of 430 construction workers in 100 construction site locations of welding in Surakarta. The sampling technique employed was multistage random sampling one. Sample was taken from 20 locations in 5 districts of Surakarta, leaving 245 welders being the sample. The knowledge is the most influential factor surrounding the practice of using protective equipment on construction workers welding in Surakarta, Indonesia. A good knowledge of welders can increase the opportunities in the good practice of using personal protective equipment up to 6 times (p value=0.001, Exp. B=6, 020).

The paradox of being on the glass cliff: why do women accept risky leadership positions?

PurposeRecent evidence from glass cliff research suggests that women are more willing than men to accept risky leadership positions. The purpose of this paper (based on three studies) is to reveal and resolve the apparent paradox that women are more risk averse than men yet end up in risky leadership positions.Design/methodology/approachIn Study I, risk attitudes of 125 participants were surveyed to understand gender differences in risk taking. In two experimental vignette studies, 119 university students (Study II) and 109 working adults (Study III) were offered a leadership position in either a risky or successful company and asked to rate their willingness to accept the job.FindingsTogether, the results showed that although women are generally more risk averse than men, women who scored low on career self-efficacy were more likely to perceive a risky job as a promotional opportunity and were therefore more willing to accept such a job. These findings shed light on the role of women’s career decision making in the glass cliff phenomenon.Originality/valueGlass cliff research has focused almost exclusively on organizational decision makers. The authors aim to better understand the glass cliff phenomenon by incorporating the perspective of job seekers.

Gender wage gaps and risky vs. secure employment: An experimental analysis

In addition to discrimination, market power, and human capital, gender differences in risk preferences might also contribute to observed gender wage gaps. We conduct laboratory experiments in which subjects choose between a risky (in terms of exposure to unemployment) and a secure job after being assigned in early rounds to both types of jobs. Both jobs involve the same typing task. The risky job adds the element of a known probability that the typing opportunity will not be available in any given period. Subjects were informed of the exogenous risk premium being offered for the risky job. Women were more likely than men to select the secure job, and these job choices accounted for between 40% and 77% of the gender wage gap in the experiments. A method for classifying subjects according to risk preferences is derived from the theoretical framework and further demonstrates the higher incidence of risk aversion among women.

Military Based Security System Using Raspberry Pi

In today’s world Indian border military force is facing a huge destruction. Hence, most of the military organizations take the help of military robots to carry out risky jobs which cannot be handled by humans. In this proposal, we design and implement in such a way that the robotic vehicle can enter into an area of higher risks, move and place wherever the object wants to go and captures intruder’s image. It has human detection Pi camera and temperature and gas detecting sensor that can provide precaution to potential crimes, fire and leakage of any gases. The credit card sized Raspberry Pi with Open Source Computer Vision (OpenCV) software controls the face detection algorithm and sends captured pictures to the user’s email via WI-FI. The pi-camera serves as the eye of the robot and provides us live video streaming. The biggest advantage of the system is that the user can get the picture of the intruder from anywhere in the world and can respond according to the risks in the situations.
 
 The prime objectives of this paper are:
 
 To find the presence of an intruder - if detects, captures images and sends it to the given email address.
 Enables control of the robotic vehicle –i.e. The robot can be moved in any directions from the user present in any location.
 To find the presence of any gases present in the surrounding other than the normal air and warns the nearby person with its buzzing.
 Can monitor the location at any remote distance via live surveillance.
 To find the temperature of the environment

Career Preferences of Agriculture and Animal Sciences Undergraduates

Undergraduates in agriculture and allied discipline, after completion of their degree, opt to join the different professional jobs depending on their preferences and the existing situations. Though they have a wide range of careers options, each one has their own preference in choosing a regarding their careers. But due to the prevailing situations, agricultural graduates are forced to take up a career in administrative services and commercial banks rather than teaching, research, and extension careers; they are low initiated take entrepreneurship and agriculture farming. Considering this present study conducted in Telangana state purposively to know the undergraduates career preferences. Government service in their major field is the most preferred career of agriculture and veterinary final year undergraduate students. Horticulture undergraduates preferred career was also government employment but in non-major field. Dairy technology undergraduates mostly preferred to work in private companies. Entrepreneurship and agriculture farming were least preferred career undergraduate students of all disciplines. The results revealed that only a few undergraduates had a preference to take own business as occupation. This may be due to the risk and insecurity attached to the self-employment at the same time government service has high social status and low risky job. The Fifth Deans committee has given detailed curriculum of student READY programme for all the disciplines in agriculture and allied sciences. The course curricula have been restructured to develop much-needed skills and entrepreneurial mindset among the graduates to take up self-employment, contribute to enhanced rural livelihood and food security, sustainability of agriculture and be a propeller for agricultural transformation.

A stochastic scheduling approach to minimise the number of risky jobs and total probability of tardiness

A stochastic scheduling approach to minimise the number of risky jobs and total probability of tardiness

A stochastic scheduling approach to minimise the number of risky jobs and total probability of tardiness

In this paper, single machine stochastic scheduling problem is addressed where jobs have probabilistic processing times and deterministic due dates. In classical scheduling literature, a job is called 'tardy' if it is completed after its due date; otherwise it's called 'early'. However, in probabilistic concept, a job can have a non-zero probability of tardiness. To capture this situation, a stochastic nonlinear mathematical model is developed. The objective is to minimise the expected number of tardy jobs and the total probability of tardiness. Experimentation is performed with datasets having varying number of jobs from 10 to 100. Results are compared with deterministic model. The proposed approach resulted in a significant decrease in the number of risky jobs and the total probability of tardiness. In addition, as the variance of processing times increased, the proposed stochastic approach provided safer schedules in terms of the total probability of tardiness.

Design of intelligent controller for reduction of chattering phenomenon in robotic arm: A rapid prototyping

Robots functioning in the place of living beings is becoming more reliable as they can endure drastic physical conditions and can operate in airless conditions. Further, they can perform risky jobs and be not bothered by the job security and reputation. Sliding Mode controller (SMC) is a robust controller that has high stability, but it suffers from the problem of chattering. Power losses and severe electromagnetic interference (EMI) noises produced by the converter due to high switching frequency yields chattering. This paper puts forth the design of a hierarchal controller using differential flatness property to track the angular velocity trajectory of permanent magnet DC motor driven by a DC-DC buck converter. A cascaded control is used to regulate the DC-DC buck converter and it aids to reduce the chattering phenomenon to a minimum level. In addition, this control enhances the performance of the system by maintaining fixed switching frequency. Experimental observations show that the angular velocity is well traced under abrupt conditions.

Sensation seeking and risk-taking in the Norwegian population

The article is based on a comprehensive study of the relation between sensation seeking and various forms of risk-taking in a representative sample of the adult Norwegian population, aged 15years and above (N=1000). The study included social, intellectual, financial, achievement-related, political, physical, ethical and existential risktaking dimensions. There was an expected main effect for age as well as gender on total sensation seeking, but no main effect for social class.All sensation seeking scales correlated positively with all the risk dimensions, although moderately for most scales. Physical risk had the highest correlation scores. The study found that altogether 21, 2% of the general population had been involved in risky activities during their life and had elevated scores on sensation seeking. A relatively high percentage of the population would be willing to be involved in risky sports (35,7%), risky jobs (54,8%) or risky military operations (25,9%), provided they were in good shape and of the right age. Those who were willing had higher sensation seeking scores.Only 16,9% of the population thought basejumping or other risk sports should be prohibited. The prohibitionists had lower sensation seeking scores than the non-prohibitionists.

Self-Esteem and Distress Tolerance of Criminology Students of the University of Bohol

Self-esteem refers to one’s overall evaluation of oneself, while distress tolerance is the ability to withstand pressures and negative emotions. Both constructs have relationships with criminal behaviors based on various studies. The policing profession is one of the most stressful and risky jobs in the whole world, hence, this study aimed to determine the self-esteem level and degree of distress tolerance of Criminology students at the University of Bohol. The research used descriptive quantitative research utilizing two standardized tools, namely, the Rosenberg Self-Esteem Scale and the Distress Tolerance Scale to determine the level of self-esteem of the respondents and to gauge the respondents’ degree of tolerance or ability to withstand negative effects or other aversive psychological and or physical states. Purposive sampling was used to get a sample from the total population. The respondents possessed high self-esteem as evidently shown by their mean score of 2.8. As revealed in the data, all the four-year levels obtained mean scores falling between the scales of 2.50-3.24 with an interpretation of high self-esteem.
