Spatial neglect in acute stroke: the line bisection test
Authors: Friedman PJ
Published: May 2023

Line bisection testing was performed on 82 elderly subjects within 14 days of a non-lacunar stroke. The 40 subjects with impaired line bisection were of similar age and pre-stroke dependency as the 42 subjects with normal line bisection but had a more severe current stroke deficit as evidenced by a higher incidence of new hemiplegia, homonomous hemianopia, visual extinction and constructional impairment, and greater power loss. Subjects with impaired line bisection had poorer functional outcome than those with normal line bisection as measured by Barthel activities of daily living scores, walking speed and discharge residence. When subjects with impaired line bisection were divided into two groups according to line bisection error, the severely impaired had worse functional outcome than the mildly impaired. After accounting for motor loss and the ability to draw a house by using logistic regression, line bisection did not contribute significantly to predicting functional outcome.

Authors: Lurie M , Caidahl K , Johansson G , Bake B
Published: May 2023

Since patients with severe chronic primary fibromyalgia (CPF) report effort dyspnoea, respiratory function was studied in 87 consecutive women with CPF according to Yunus' criteria. Bernstein spirometry, maximum inspiratory (MIP) and expiratory (MEP) pressures were obtained in patients, and in a reference group of 61 healthy women. MIP was considerably lower in patients than in controls (3.6 +/- 2.0 vs. 8.0 +/- 2.2 kPa, p less than 0.0001), as was MEP (3.1 +/- 2.1 vs. 8.3 +/- 2.2 kPa, p less than 0.0001). Patients who had previously reported dyspnoea at a bicycle exercise test showed significantly lower values of respiratory pressures than patients without dyspnoea. Respiratory pressures were reproducibly low in CPF patients. Spirometric values were normal among patients and controls. We conclude that maximum expiratory and inspiratory pressures are low in CPF, a finding which may indicate respiratory muscle dysfunction in this syndrome.
Can high-risk patients after myocardial infarction participate in comprehensive cardiac rehabilitation?
Authors: Hedbäck B , Perk J
Published: May 2023

Patients with large transmural infarctions (MI) and signs of congestive heart failure (CHF) are often excluded from physical training, because of the risk of malignant arrhythmia or cardiac overloading. From a non-selected MI population less than 65 years we enrolled 37 high-risk patients in a two-year comprehensive cardiac rehabilitation programme, including health education, follow-up at a post-MI clinic, and physical training in outpatient groups. The feasibility, effectiveness and safety of the physical training were evaluated: Twenty-one patients joined the physical training and participated with excellent compliance, reaching the preset levels of training. No adverse effects occurred during the 921 training sessions. The high-risk patients were compared with the remaining 228 patients and a subgroup of 86 low-risk patients with regard to mortality, morbidity, medication, effect on risk factors, exercise test performance and rate of return to work. The high-risk group showed a higher mortality (27.0 vs. 10.4%, p less than 0.05), a lower maximal work capacity at the exercise test 4 months after MI (126 W vs. 140 W, p less than 0.05), and a lower rate of early return to work (22.6 vs. 50% p less than 0.01) when compare with the low risk group. However, they showed a similar improvement in exercise test parameters. At the end of the programme a remarkable 63% had returned to work vs. 48.2% of the remaining patients. The reduction in smoking and the effect on blood pressure were equal in both groups. It is concluded that high-risk patients may well benefit from regular physical training in outpatient groups, if adequate medical supervision is available.
Pressure pain threshold on upper trapezius and levator scapulae muscles. Repeatability and relation to subjective symptoms in a working population
Authors: Takala EP
Published: May 2023

The pressure pain threshold for the upper trapezius and levator scapulae muscles was studied in a working population with a mechanical algometer. The lower 95% confidence interval limits of the correlation coefficient describing intraobserver reliability varied from 0.71 to 0.92, measured in 93 men and 70 women. The values describing interobserver reliability varied from 0.68 to 0.79, measured only in men. The day-to-day repeatability was measured in 10 women and it proved to be acceptable. In general, women had lower pain threshold values than men. Low values were related to complaints in the neck and shoulder region. However, the values in the non-symptomatic population displayed wide variation. Though unsuited for use as a primary diagnostic or screening tool, the method shows promise for application in individual follow-up studies as an outcome measure in therapeutic trials.
Psychosocial job factors and symptoms from the locomotor system--a multicausal analysis
Authors: Theorell T , Harms-Ringdahl K , Ahlberg-Hultén G , Westin B
Published: May 2023

The effects of physical and psychosocial work environment factors on emotions, psychosomatic and endocrine (cortisol and testosterone) states, back pain, symptoms of degenerative joint disease, and absenteeism for sickness, were studied in 147 men and 60 women in six occupations representing widely different physical and psychological activities. In most subjects, measurements were carried out twice to four times over one year. Statistical analyses were performed of the associations between different factor levels, such as age, gender, height, body mass index, and physical stressors at work. It was found that psychological work demands were associated with physiological indicators of strain (plasma cortisol and self-reported muscle tension) and that self-reported muscle tension was associated with several emotional reactions as well as with symptoms from the back, neck and shoulders. Little possibility for decision-making was associated with a high rate of absenteeism for sickness. In men, a high plasma testosterone level was associated with self-reported muscle tension. The results indicate that work environment factors influence mood, bodily tension and somatic symptoms, but that load on the locomotor system and opportunity to influence decisions play an important and more direct role in absenteeism for sickness

Vocational rehabilitation in northern Sweden. II. Some psycho-socio-demographic predictors
Authors: Eklund M , Eriksson S , Fugl-Meyer AR
Published: May 2023

In this prospective investigation a consecutively referred series of vocational rehabilitation clients was studied using eleven socio-demographic and psycho-social items. Subjected to a factor analyses these items were included in five factors which explained 74% of the variance. By discriminant analysis the items could correctly classify 57% of those subjects who faced major vocational changes or were vocationally inactive. The level of experienced health and belief in vocational return had the heaviest overall predictive impact. The findings may help specialists in medical and vocational rehabilitation to estimate the likelihood of vocational return for somatically impaired subjects.
Vocational rehabilitation in northern Sweden. III. Aspects of life satisfaction
Authors: Fugl-Meyer AR , Eklund M , Fugl-Meyer KS
Published: May 2023

Levels of global (1 item) and domain-specific (8 items) life satisfaction were explored at the commencement of vocational rehabilitation and two years later in a consecutive series of subjects who were partly or completely vocationally disabled with a diagnosis of bodily impairment. At the onset of vocational rehabilitation, global life satisfaction (satisfaction with life as a whole) and satisfaction derived from performance- and provider-related (instrumental) domains of life were significantly lower than satisfaction derived from socio-emotional (expressive) facets of life. The eight domain-specific items of life satisfaction described a characteristic three-factor pattern (76% of variance) which resembled quite closely that of non-impaired subjects, one factor being expressive. The other two factors were instrumental and separated recreative from vocational domains of satisfaction. Successful vocational rehabilitation resulted in increases in vocational satisfaction. For those subjects who were successfully rehabilitated, satisfaction with other instrumental aspects of life and with life as a whole also increased. The results indicate that successful vocational rehabilitation leads to increased social well-being.
Effects and follow-up of a multimodal treatment program including intensive physical training for low back pain patients
Authors: Estlander AM , Mellin G , Vanharanta H , Hupli M
Published: May 2023

The results of a comprehensive 4-week treatment program including intensive physical training were evaluated in 65 chronic low back pain patients. Marked increases in measures of spinal mobility, trunk muscle strength and lifting capacity were found during the treatment, but no average increase in pain ratings. At 3-week and 12-month follow-ups a statistically significant decrease in subjective disability and pain was found, but the percentage of patients who were working was unchanged. This points to a need for more work-oriented rehabilitation efforts in the treatment.
Diagnostic blocks of the tibial nerve in spastic hemiparesis. Effects on clinical, electrophysiological and gait parameters
Authors: Arendzen JH , Van Duijn H , Beckmann MK , Harlaar J , Vogelaar TW , Prevo AJ
Published: May 2023

The value of a diagnostic block (DB) of the tibial nerve in 17 hemiparetic patients with gait disturbances was investigated. The purpose of this study was to find instruments that help to select patients who will benefit from a long lasting peripheral nerve block. The manually elicited ankle clonus and its abolition after injection of a local anaesthetic appeared to be a useful clinical test for the efficacy of DB. Electrophysiological tests proved valuable when DB failed to produce clinical effects. With a substantial number of blocked nerve fibres walking velocity did not deteriorate. Transient disturbances in sensation can be regarded as unwanted side effects that might adversely affect the walking ability. From the different aspects of gait an improved heelcontact demonstrated the functional gain in patients with a dynamic equinus foot. To differentiate between a dynamic equinus foot and fixed contractures, we recommend the use of a fast acting local anaesthetic for diagnostic nerve blocks.
Acoustic cues and postural control
Authors: Petersen H , Magnusson M , Johansson R , Akesson M , Fransson PA
Published: May 2023

The effect of auditory input on postural control was evaluated in separate experiments performed in three groups of healthy volunteers. Auditory input took the form either of feedback signals generated by a force platform in response to the subject's postural control movements, or of field orientation (frame of reference) input provided by repeated clicks emitted by loudspeakers in a normally reverberative environment. The effect of these acoustic cues was measured in terms of body sway recorded on a force platform during stance perturbations induced by vibratory stimuli applied to the calf muscles either at low (120mW) or high (850 mW) intensity, the subject standing with eyes closed or open, as instructed. In the presence of feedback auditory input, body sway in response to low intensity vibratory stimulation was significantly reduced, but not that in response to high intensity stimulation. This may be due to the fact that the head and body movements induced by high intensity vibratory stimulation are so rapid and powerful that they override the information available or to the subject using other strategies for postural control in which auditory feedback, at least in the form used here, does not contribute useful information. The availability of field orientation input did not reduce body sway in response to vibratory stimulation at low intensity. This was probably due to the cognitive lag which precluded use being made of the input before the fast proprioceptive responses to vibratory stimulation had already occurred.

Published: May 2023

42 stroke patients with verified right hemisphere lesions were studied. Depressed mood was measured by means of a global rating scale, and an inventory administered as a structured interview. As measured by the global ratings and one of the inventory subscales, patients with deep, retrorolandic lesions showed significantly more depressed mood than other patients. The findings are discussed in the light of current relevant research, and implications for management of depressed mood in stroke patients are suggested.
Mechanical performance, level of continuous contraction and muscle pain symptoms in home care personnel
Authors: Elert J , Brulin C , Gerdle B , Johansson H
Published: May 2023

The interrelationships between reported complaints, clinical status, mechanical performance and EMG pattern of the shoulder flexors and the knee extensors, respectively, during maximum dynamic contractions were investigated. A group of 97 randomly selected women employed in the home care service participated. Those who reported complaints had more clinical findings, such as reduced mobility, tender points and muscle tightness, than non-complainers. The level of muscle activity during the passive part of the contraction cycle was significantly higher in the shoulder flexors than in the knee extensors. Subjects without reported complaints who had been employed for more than ten years had a significantly lower activity level in the shoulder muscles than subjects without complaints who had been employed for a shorter time. We suggest that a high muscle tension level between contractions might precede muscle pain. A cluster analysis including sociodemographic, clinical and physiological variables revealed different subgroups, which points to the need to investigate the work situation in a multivariate way.

Gadget addiction is considered to be quite worrying in the current era of globalization, especially in the younger generation, which is detrimental to national development, especially at the city, provincial, regional and even village levels. Meanwhile, the laws and regulations regarding gadgets for oneself and others have been explained in Article 30 paragraph (1) of the ITE Law, namely that every person intentionally and without rights or unlawfully accesses another person's computer and/or electronic system in any way. Article 27 paragraph 3 of the ITE Law states that it prohibits everyone intentionally and without rights from distributing and/or transmitting and/or making Electronic Information and/or Electronic Documents accessible that contain insults and/or defamation. Seeing other people's cellphones without permission is an illegal act that cannot be justified. Based on Article 30 paragraph 1 of the ITE Law, the legal rule of viewing another person's cellphone without permission can be Article 32 paragraph (1): "Every person intentionally and without rights or against the law in any way changes, adds, subtracts, transmits, destroys, removes , move, hide electronic information and/or electronic documents belonging to other people or public property." causing the said person to be imprisoned or given sanctions according to his actions. The reasons why teenagers use gadgets are low self-control, feeling lonely, and sensation-seeking behavior. The role of parents, teachers, government agencies and society determines the future of adolescents, such as roles: parents; Teaches right/wrong and good/bad behavior standards and shows exemplary behavior standards. Teacher's Role; the teacher has the duty to encourage, guide, and provide learning facilities for students to achieve goals.

Pregnant women and their fetuses — orphan populations in respect to the safety and efficacy of medicines
Authors: Ushkalova EA , Zyryanov SK , Butranova OI
Published: May 2023

Pregnant women are a very special category of patients. The risk-benefit ratio of using various drugs in this case presents a significant medical, social and ethical problem. The increase in the age of onset of the first pregnancy is associated with the increasing prevalence of chronic pathology. Obesity, cardiovascular diseases, diabetes mellitus, hypo- or hyperfunction of the thyroid gland, as well as many other conditions contribute to the active use of drugs of various pharmacological groups throughout the entire period of pregnancy, including early periods. The current practice of pharmacotherapy in pregnant women is based mainly on the use of drugs with an uncertain teratogenic risk. Not including pregnant women in clinical trials is an ethical issue as significant as their potential inclusion. Previously, for a long time, vulnerable categories included generally all women of reproductive age, whose inclusion in clinical trials became possible only in the mid-1990s. Pregnant women were considered vulnerable until 2019. The orphan status of pregnant women in terms of inclusion in clinical trials limits their right to receive highly effective and safe medical care, which makes it relevant to review the existing ethical principles in relation to this category of patients and a to perform a detailed analysis of existing barriers for certain types of drug trials.

Tenuipalpidae (Trombidiformes: Tetranychoidea) is an economically important family of plant-feeding mites. The family has approximately 1,100 described species in 41 genera with worldwide distribution. Currently, 40 species of Tenuipalpidae have been recorded from Brazil, and prior to this study only 11 were known from Bahia state. Five new species records are presented here for Bahia, making a total of 16 species now known from the state. Brevipalpus is considered the most important genus due to their association with, and ability to transmit, devastating plant viruses. Some diseases caused by viruses transmitted by Brevipalpus mites (VTBs) have already been recorded in the state of Bahia, such as the Passion fruit green spot virus and citrus leprosis. This paper presents a checklist of tenuipalpids reported from the state of Bahia in Brazil, including new records and an illustrated identification key to the species.

Published: May 2023

Aim

Atrial fibrillation is a multifaceted disease requiring personalized treatment, in accordance with current ESC guidelines. Despite a wide range of literature, we still have various aspects dividing the opinion of the experts in rate control, rhythm control and thromboembolic prophylaxis. The aim of this survey was to provide a country-wide picture of current practice regarding atrial fibrillation pharmacological management according to a patient's characteristics.

Methods

Data were collected using an in-person survey that was administered to members of the Italian Association of Arrhythmology and Cardiac Pacing.

Results

We collected data from 106 physicians, working in 72 Italian hospitals from 15 of 21 regions. Our work evidenced a high inhomogeneity in atrial fibrillation management regarding rhythm control, rate control and thromboembolic prophylaxis in both acute and chronic patients. This element was more pronounced in settings in which literature shows a lack of evidence and, consequently, the indications provided by the guidelines are weak or absent.

Conclusion

This National survey evidenced a high inhomogeneity in current approaches adopted for atrial fibrillation management by a sample of Italian cardiologist experts in arrhythmia management. Further studies are needed to explore if these divergences are associated with different long-term outcomes.
Numerical Investigation of Production-Related Characteristics Regarding their Influence on the Fatigue Strength of Additively Manufactured Components
Authors: Zeißig Michaela , Jablonski Frank
Published: May 2023

In order to further enhance the application of additive manufacturing (AM) processes, such as the laser powder bed fusion (L-PBF) process, reliable material data are required. However, the resulting specimen properties are significantly influenced by the process parameters and may also vary depending on the material used. Therefore, the prediction of the final properties is difficult. In the following, the effect of residual stresses on the fatigue strength of 316L steel, a commonly used steel in AM, is investigated using a Weibull distribution. The underlying residual stress distributions as a result of the building process are approximated for two building directions using finite element (FE) models. These imply significantly different distributions of tensile and compressive residual stresses within the component. Apart from the residual stresses, the impact of the mean stress sensitivity is discussed as this also influences the predicted fatigue strength values.

As ecological problems are rapidly expanding, they bring with them increasingly threatening and drastic complications. On the other hand, the economic benefits of plastic products have created a dilemma for consumers and business owners. Since one of the main channels for satisfying daily needs is online shopping and social media, and the market share of electronic commerce is growing inexorably compared to traditional brick-and-mortar methods, it would be useful to understand the factors related to consumer behavior on these platforms in order to resolve environmental issues. This research attempts to identify the factors affecting green consumer purchase decisions on social commerce platforms. A questionnaire was designed based on data gathered using bibliographic methods, and collected data from 532 valid samples was analyzed using SmartPLS software. According to the findings, subjective norms such as social network inference is positively correlated to green product attractiveness. In addition, the results show that personality traits and green product attractiveness are positively correlated; moreover, the results show that there is a positive relation between green advertising and green product attractiveness. It is believed that the outcomes of this research will contribute to and be beneficial for manufacturers and businesses by proposing a new model for green marketing and green product awareness.

Exploring Chinese College Students' Awareness of Information Security in the COVID-19 Era
Authors: Wang Xinran
Published: May 2023

The focus of this research was to look into the information security awareness of Chinese university students during the COVID-19 pandemic and make recommendations based on the survey's findings and research literature. The quantitative method is applied in this study. 111 Chinese college students were randomly sampled and requested to answer a Likert information security awareness questionnaire. The descriptive analysis of the data in this study is also done with SPSS. The findings revealed that the vast majority of college students know the significance of information security awareness and have basic information security awareness, based on the data collected. However, some students have not participated in relevant training courses, and many college students do not pay enough attention to personal information security, resulting in poor performance in areas such as files and passwords. As a result, effective solutions such as information security training projects are required to address the current deficiencies. The findings of this study have implications for university administrators and policymakers in terms of how to raise students' awareness of the security of their online learning information. The study should use mixed methods and large sample sizes in the future to provide more detailed and comprehensive survey data, and more credible evidence of college students' information security awareness.

Does the Effectiveness of Monetary Policy Depend on the Choice of Policy Instrument? Empirical Evidence from South Korea
Authors: Zuniga Martha Cruz , Senbet Dawit
Published: May 2023

This study provides robust evidence on how the choice of the policy instrument for monetary policy influences its impact on economic activity. We study the case of South Korea for the period 1980-2017. We use FAVAR models that allow a comprehensive exploration of different areas of economic activity by overcoming limitations on a number of variables that can be included in the analysis in a traditional VAR model. Following the actual use of instruments, we test the effectiveness of monetary policy in two separate periods: 1980-1999, when the Bank of Korea mostly used M2 as the policy instrument; and then 2000-2017, when interest rate was the policy instrument. Our results show that monetary policy that uses interest rate as the policy instrument is markedly more effective in economic activity than M2. This is observable in the reaction from prices as well as variables that measure industrial production. In contrast, the impact of M2 mostly occurs in prices and it is short lived. We use robustness checks that switch the use of instrument for each subperiod and also test the use of each policy instrument for the entire period of analysis.

Lowering Social Desirability Bias: Doing Jokes-Based Interviews
Authors: Bouwmeester Onno
Published: May 2023

Jokes-based interviews can help to reduce social desirability bias of responses on sensitive topics, such as unethical business behaviour or other norm transgressions. The jokes-based interview method is relevant for academic researchers, as well as for practitioner researchers such as consultants, or journalists. The method uses public jokes as invitation to reflect on work experiences related to the jokes, such as pressuring leadership, dirty work, or work-life conflict that tend to be normalised. Illustrated for a critical leadership cartoon, the interview method triggers junior consultants’ memories of experiences with pressuring managers, and managers’ memories of how their juniors deal with overly high leadership demands. The method creates rapport, as the business jokes not only introduce the topic, but also serve as an icebreaker. When applying the method, joke selection is key, as some jokes introduce the topic better than others. Cartoons are especially good at inviting an open conversation on norm transgressions relating to ethics, aesthetics, or social norms. Interviewees also need sufficient room to freely interpret, associate, and elaborate. Next, follow-up questioning is important, and preparing a topic list may help to do so. Some limitations to this method are that jokes can become leading, and that interviewees do not give authentic answers. Therefore, it is important to use public jokes and to keep distance as a researcher: do not make these jokes yourself. Also consider that business jokes are critical, and that jokes-based interviews initially do not invite reflection on the positive side of business life. However, in the follow up conversations this may very well happen.

Authors: Klapita Vladimír
Published: May 2023

In a pandemic situation such as Covid-19, it is essential to keep contact to a minimum, but it is also important to maintain an acceptable supply level to the population. This paper presents a general analysis of selected exponential logistics technologies, particularly the possibilities of their use in the implementation of logistics chains, or the segment related to storage and distribution during a pandemic. Exponential technologies are those whose performance doubles yearly, but whose cost is halved. Five logistics technologies have been selected that meet the exponentiality criteria and can address pandemic-related issues under certain conditions. Each of these technologies can be used in specific segments of logistics systems. The technologies meet the exponentiation criterion and contribute to increased performance, efficiency, and process automation These technologies are becoming part of a new approach to logistics and are directly related to the advent of Industry 4.0. This paper analysis and subsequent application concern logistics technologies such as internet of things, automated guided vehicles, drones, digital twins, and artificial intelligence.

The COVID 19 pandemic has created blocks in our society that have affected all areas of our lives. One of the areas that have been affected most significantly is the transport sector. Due to the restrictions against the spread of the pandemic, public transport suffered huge losses. The aim of this contribution is to point out the changes in the traffic behavior of the inhabitants of Slovakia due to the COVID-19 pandemic. For this purpose, the data obtained using a questionnaire survey, which was carried out during 2021 by the inhabitants of Slovakia, served this purpose. It was found that during the strongest waves of the pandemic, residents avoided using public transport and switched to other modes of transport, primarily individual car and pedestrian transport. The main reason was safety and health concerns.

Published: May 2023

The article deals with creating the innovation transfer model “science - production – business”. It is based on quantitative indicators for assessing the external environment and market analysis, the landscape for implementing the development and introduction of innovation and evaluating the internal environment and the level of readiness for implementation. The authors provide ways of commercializing the scientific research results and describe the role of an entrepreneurial university in achieving the main tasks of innovation and technology transfer. A combined SPACE-RL model for assessing the prospects for new scientific ”products” concerning external and internal influencing factors is proposed. The SPACE matrix, from a subjective assessment tool based on qualitative indicators determined by experts, has turned into a SPACE-RL model, in which it is possible to compare the entrepreneurial university's capabilities in terms of the strategy of bringing the invention to the market and the readiness of the invention to become innovation The SPACE-RL model maximally objectifies the innovation transfer process, reducing the influence of qualitative factors on decision-making.
Enhancing the Renewable Energy and GDP Share of Agriculture in Indonesia: Analysis of the Impacts on Agricultural Sector Employment
Authors: PRİLLİADİ Hilmy
Published: May 2023

Renewable energy capacity, agricultural sector GDP, and agricultural employment in Indonesia experienced a downward trend from 1990 to 2019. This trend negatively impacts Indonesia’s target to utilize renewable energy as its energy source, employment in the agricultural sector, and the importance of agriculture to the Indonesian economy. Based on these issues, this research examined the impact of renewable energy usage and agricultural sector GDP on the employment rate of the agricultural sector by implementing the Autoregressive Distributed Lag (ARDL) model. According to empirical findings, total renewable energy supply improves agricultural sector employment in the short and long run; however, agricultural sector GDP improves employment only in the short run and negatively impacts the long run. It suggests that renewable energy has the potency to enhance agricultural employment. The use of renewable energy is expected to be a solution for the decrease in employment in the agricultural sector along with the GDP decrease. Governments can make sure that all funds allocated to an agroecological program or policy are used to increase agricultural renewable energy use. Renewable energy regulations should be assessed based on their ability to reduce pollution while also ensuring a reliable energy supply for the agricultural sector at an affordable price.
