Microtask Crowdsourcing for Music Score Transcriptions: An Experiment with Error Detection

Human annotation is still an essential part of modern transcription workflows for digitizing music scores, either as a standalone approach where a single expert annotator transcribes a complete score, or for supporting an automated Optical Music Recognition (OMR) system. Research on human computation has shown the effectiveness of crowdsourcing for scaling out human work by defining a large number of microtasks which can easily be distributed and executed. However, microtask design for music transcription is a research area that remains unaddressed. This paper focuses on the design of a crowdsourcing task to detect errors in a score transcription which can be deployed in either automated or human-driven transcription workflows. We conduct an experiment where we study two design parameters: 1) the size of the score to be annotated and 2) the modality in which it is presented in the user interface. We analyze the performance and reliability of non-specialised crowdworkers on Amazon Mechanical Turk with respect to these design parameters, differentiated by worker experience and types of transcription errors. Results are encouraging, and pave the way for scalable and efficient crowd-assisted music transcription systems.
An Analysis of News Coverage on the Filibuster for the Anti-Terrorism Act

This study aims to analyze how the Korean liberal and conservative newspapers cover the filibuster for blocking the passage of the anti-terrorism act for the protection of citizens and public security by the main opposition party. For the comparative analysis of the Korean liberal and conservative newspapers, this study analyzes how the newspapers used news frame, news source, key word, and news theme. To analyze the effects on news coverage of the newspapers’ ideological orientation, this study selects six newspapers: Hankyoreh Shinmun, Kyunghyang Shinmun, Ohmynews from liberal newspapers and Chosun Ilbo, Donga Ilbo, Joongang Ilbo from conservative newspapers. According to research findings, the liberal and conservative newspapers show clear distinction while using news frames when the newspapers cover the filibuster. The liberal newspapers cover the filibuster as a positive political action while the conservative newspapers cover the filibuster as a negative political action. In addition, as key word, “disturbance” is mentioned most by the conservative newspapers while “poisonous clauses” is used most by the liberal newspapers. As a result, this study shows that newspapers are influenced by ideological orientations while covering political issues. ■ keyword :∣Science Technology∣News frame∣Filibuster∣National Assembly∣The Anti-Terrorism Act∣ * 이 연구는 2018년도 성공회대학교 교내연구활동지원사업에 의한 연구임 접수일자 : 2020년 06월 12일 수정일자 : 2020년 08월 21일 심사완료일 : 2020년 08월 28일 교신저자 : 최진봉, e-mail : choi0126@gmail.com 한국콘텐츠학회논문지 '20 Vol. 20 No. 9 196
The Dynamics of Employee Voice: Evidence from Nigeria

Employee voice and its presumed relevance in achieving improved organizational performance has become a recurring rhetoric in the employment relationship. This study explored the existence and functioning of employee voice schemes in organisations in South-South Nigeria. Survey data from 307 respondents from across five economic sectors were used. The data were analyzed using mainly descriptive statistics and the two hypotheses were tested using Spearman Rank order correlation coefficient. Results indicated the existence of a variety of employee voice schemes; that managers support the schemes and there was employees perception of say in how work is organized. However, based on the results, the study concludes that managers seem to commit to voice schemes that do not diminish their managerial prerogative. It also concluded that the meaning of “say” for both managers and employees appears to lie closer to a lower order voice category, wherein there is mere exchange of information rather than real involvement of employees in the making of workplace decisions. We recommend that considering the acclaimed relevance of employee voice, with respect to organisational performance, employers should wholeheartedly embrace employee voice systems and consciously encourage active involvement of employees, particularly those competent, knowledgeable and interested, in making decisions at work.
Development of amphotericin b Based organogels against mucocutaneous fungal infections

Amphotericin B is a broad spectrum antifungal agent used to treat fungal infections. Organogel is a semisolid preparation in which the apolar phase gets immobilized within spaces of the threedimensional structure. The current study aimed at the formulation and comparative evaluation of sorbitan monostearate organogels and pluronic lecithin organogels (PLO). Different compositions of span 60 based organogels were prepared by varying the concentrations of the span 60 and PLO gels were prepared by varying the concentration of Pluronic F 127. The developed organogels were subjected to various characteristics such as pH, viscosity, spreadability, extrudability, and drug release studies. The optimized formulations were evaluated against Candida albicans and carried out ex vivo release study. The optimized formulation was selected from span 60 based organogels, and pluronic lecithin organogels were S1 and P1, respectively. The optimized formulation (S1) showed effective inhibition against Candida albicans. The skin irritation test was carried out on albino mice for optimized formulations and results showed that no irritation to the skin. Based on the results, organogels prepared by sorbitan monostearate showed better antifungal activity, and also all the formulations were found to be stable and safe throughout the study period.
Growth Analysis of Genetically Modified Cassava (Manihot esculenta Crantz) Plants Expressing NPT II Marker and GUS Reporter Genes

Background: Cassava is an important root crop with many biotic and abiotic problems. Genetic modification is a viable option for improvement of cassava to against the production constraints. Objectives: The growth and morphology of cassava transgenic plants modified with NPT II marker and GUS reporter genes andnontransgenic (wild) cassava plants were compared to reveal difference between them. Method: The study had two experiments: in the first experiment, external morphology and quantitative growth assessment of transgenic and non-transgenic plants were examined. Growth patterns and growth correlations in plants raised from three types of stem cutting were examined in the second experiment. Results: The external morphology of the transgenic TME 12-2010 were not different from non-transgenic TME 12.However,the shape of the leaf lobe was arched in the transgenic TME 12-2010 but obovate in non-transgenic TME 12. Whether a plant is transgenic or non-transgenic, it had no influence on sprouting percentage, number of sprout per cuttings, leaf area, number of leaf, number of root per plant and total dry weight. However, sprouting percentage, number of sprout per cuttings, leaf area, number of leaf, number of root per plant, total dry weight depended on type of cuttings used as planting materials.Irrespective of types of TME and stem cutting, pattern of growth of stem, leaf, RGR, LAR, NAR and CGR were similar from planting to 8 MAP. Conclusion: Genetic modification of cassava with NPT II and GUS genes caused no growth alterations to the plant and thus, similar agronomic practices should be given to both transgenic and non-transgenic cassava plants.
Waterscape, State and Situation of China’s Water Resources

Water is one of the most critical issues of concern in China’s ongoing rapid economic development. The resource is scarce and demand is growing as China becomes more industrialized and urbanized. The situation is exacerbated by natural and anthropogenic events such as climate change, pollution, exorbitant patterns of water consumption, and an uneven distribution of water resources, with devastating impacts on ecosystems, international relations, food security and public health. In this paper, an overview of China’s water resources is presented. Studies on distribution, consumption patterns and pollution of water resources are reviewed in order to understand the over-exploited and unexplored dimensions of the Chinese water landscape. The status of water resources is also studied with an intention of providing information on the dynamics of water quality and quantity. The paper concludes with a discussion on China’s commitment to rebalancing its water growth model and the measures taken to achieve that.
The Evolution and Interdisciplinarity in the Research on Phytoremediation of Organic Pollutants: The Case of TNT

Resumo Abstract: Phytoremediation is defined as a set of technologies that employ plants and their associated microorganisms to reduce the concentrations or toxic effects of contaminants present in the environment. The phytoremediation of organic pollutants in large scale requires a transversal approach of the knowledge about the plant/pollutant/soil interaction comprising the routes of metabolization, phytotoxicity of the pollutant on the phytoremediation species and the search for greater efficiency of the process. Research on TNT (2,4,6-trinitrotoluene) is an example of the evolution in phytoremediation of organic contaminants. The limitations to the application and commercialization of phytoremediation are being overcome through the evolution of research and knowledge integration in different areas.

Abbott⋅Chol Shin Institute of Human Genomic Study, College of Medicine, Korea University Ansan Hospital Department of Biomedical Laboratory Science, College of Health Science, Jungwon University Constitutional Medicine and Diagnosis Research Group, Korea Institute of Oriental Medicine Department of Nursing, Korea Nazarene University Department of Food and Nutrition, College of Health Science, Kangwon National University Department of Pulmonary, Sleep and Critical Care Medicine, College of Medicine, Korea University Ansan Hospital College of Medicine, Korea University Object Although Taeeum and Soyang constitutional types have bigger body shapes and higher body mass index values than those with the Soeum, the relationship between the Sasang constitutional type and bone mass density is controversial and the association of osteopenia and osteoporosis remains unknown. Therefore, we investigated the relationship between bone mineral density, osteopenia, and osteoporosis according to Sasang constitutional type. Methods A total of 2,508 participants were included in this study. Among the study participants, 1,396 had Taeeum type, 276 had Soeum type, and 836 had Soyang type, respectively. The relationships to bone mass density, osteopenia, and osteoporosis in those with Sasang constitutional type were estimated using logistic and linear regression models. Results Bone mass density was significantly higher in the order of Taeeum, Soyang, and Soeum group (p < 0.01). Soeum group in comparison with Taeeum or Soyang group was significantly associated with a high odds ratio for osteopenia and osteoporosis except in the hip and femoral neck in the comparison of Taeeum and Soeum group (p < 0.01). Moreover, the bone mass density of Soeum group decreased more rapidly as the age increased when compared with Taeeum and Soyang group. Conclusions Our findings may contribute to the early prevention and management of high-risk individuals with poor bone mass density, osteopenia, and osteoporosis using Sasang constitution medicine.
La fatiga y la carga mental en los teletrabajadores: a propósito del distanciamiento social

Fatigue and mental workload among workers: about social distancing Background: Covid-19 is a latent threat; a sector of the population with a labor obligation carries out its work not in person in an unplanned context due to the extraordinary social distancing expressed in remote work, without previous experience in many cases and with health exposure due to psychosocial risk factors conditioning stress. Our objective was to describe the fatigue and mental burden in teleworkers through a bibliographic review, of interest for occupational health, public health, clinical research, psychology and other areas of knowledge. We also intend to inform the community about these issues to promote safe telework and ensure a balanced quality of life. Methods: Structured information on the topics of fatigue and mental load was presented, based on the analysis of international literature, mainly from recent years, obtained from the search engine reviews of scientific publications Ebsco, PubMed, and supplemented with Google Scholar, according to recognized thesauri, in English and Spanish. Results: There are also psychosocial risks in teleworking; work-related stress can be linked to fatigue, which should also be addressed as a psychosocial risk. Fatigue, although multi-causal, can be occupational in origin and may be conditioned by various aspects of labour, such as the mental workload, which is pernicious at its extremes. Conclusions: We conclude that both fatigue and mental workload must be watched, their extremes threaten the quality of work life.
Molecular characterization of L. sativus L. collection based on ISSR markers

of L. sativus L. collection based on ISSR markers- Vol 52, No.2, Inter simple sequence repeat (ISSR) marker system was used to evaluate the genetic diversity of local and introduced grasspea ( Lathyrus sativus L.) genotypes. A total of 144 bands were amplified using 10 ISSR markers, of which 122 were polymorphic among the accessions. The percentage of DNA polymorphism varied from 66.6% to 96%, with a mean of 86%. UBC 857, UBC 810 and UBC 835 with high effective multiplex ratio (EMR), marker index (MI) and resolving power (RP) values were estimated as the most informative primers for distinguishing L. sativus genotypes. High genetic diversity was detected in the grass pea germplasm. The genetic diversity index (GDI) ranged between 0.42 and 0.92, with an average value of 0.75 for the whole collection. The cluster analysis with 5000 bootstrapping value divided grasspea accessions into four major clusters. Most accessions were placed into the same cluster close to each other with regard to their botanical varieties. Principal coordinate analysis (PCoA) agreed with the cluster analysis and clearly discriminated the accessions into two genetically distinct groups. The first three coordinate axes accounted for 84.3% of the total variation. The result of the cluster and PCoA analyzes underline the importance of consideration of botanical variety traits in grasspea breeding programs. It can be concluded that the present germplasm constitutes an important pool of diversity for further genetic analysis, linkage mapping and breeding activities.
On the Effects of Structural Coupling on Piezoelectric Energy Harvesting Systems Subject to Random Base Excitation

The current research investigates the novel approach of coupling separate energy harvesters in order to scavenge more power from a stochastic point of view. To this end, a multi-body system composed of two cantilever harvesters with two identical piezoelectric patches is considered. The beams are interconnected through a linear spring. Assuming a stochastic band limited white noise excitation of the base, the statistical properties of the mechanical response and those of the generated voltages are derived in closed form. Moreover, analytical models are derived for the expected value of the total harvested energy. In order to maximize the expected generated power, an optimization is performed to determine the optimum physical and geometrical characteristics of the system. It is observed that by properly tuning the harvester parameters, the energy harvesting performance of the structure is remarkably improved. Furthermore, using an optimized energy harvester model, this study shows that the coupling of the beams negatively affects the scavenged power, contrary to the effect previously demonstrated for harvesters under harmonic excitation. The qualitative and quantitative knowledge resulting from this analysis can be effectively employed for the realistic design and modelling of coupled multi-body structures under stochastic excitations.
Airborne FMCW SAR Sparse Data Processing via Frequency-Scaling Algorithm

Using the continuous-wave technology to replace the conventional pulse-mode, frequency-modulation continuous-wave (FMCW) synthetic aperture radar (SAR) has shown good potentials of reducing the weight of the system and the sensors’ peak transmission power. In order to relax the requirements of data bandwidth and storage, and increase the swath, the SAR system will collect the downsampled data, which makes the traditional matched filtering (MF)-based method unable to recover the considered scene, leading to failed reconstruction. To solve this problem, this letter presents an FMCW SAR sparse imaging method based on the frequency-scaling algorithm (FSA). Experimental results on the real data show that compared with the MF-based FMCW SAR imaging algorithms, the proposed method can improve the recovered image performance effectively. For the sparse surveillance region, it can achieve accurate recovery even from the downsampled data. Because the computational complexity of the proposed method is in the same order as that of MF, the sparse imaging of large-scale scenes can also be realized in the FMCW SAR.
Collector System Topology Design for Offshore Wind Farm's Repowering and Expansion

After decades of operations, the first batches of offshore wind farms (OWF) are approaching the end of service lifetimes, while the demand for energy transformation is continuously pushing countries around the globe to construct larger OWFs. Therefore, the old OWF's repowering and scale-expansion becomes a possibly-feasible plan which deserves more researches. This paper firstly analyzes the potential benefits of combining the repowering and expansion parts in collector system topology design, which is followed by further analysis and mathematical verifications of economy and reliability advantages for applying cross-substation incorporation (CSI) to the collector system. To achieve the optimal topology design for OWF repowering and expansion, this paper also proposes a multi-layer optimization framework that consists of an offshore substation (OS) refinement layer, an OWF partition layer, and an intra-zone cable connection layer. The whole optimization concerns the wind turbine (WT) capacity deviation between the repowered part and the expanded part, and the final output is generated with the aim of achieving optimal economy and reliability. The proposed topology is tested and compared with traditional radial and ring topologies on a benchmark collector system, and the results verify the high performance in the economy (both short-term and long-term) and reliability.
Eye-Tracking the City: Matching the Design of Streetscapes in High-Rise Environments with Users’ Visual Experiences

Large cities in the West respond to an ever-increasing shortage of affordable housing by accelerating the process of urban densification. Amsterdam, for instance, aims to increase its housing stock by 10 percent in the next 15 years as its population is expected to grow by 20 percent. As in other cities, it seems inevitable that high-rise buildings with higher skyscrapers than in the past will be built within the existing urban fabric. Such large-scale (re)development projects shape the conditions for inhabitants’ eye-level experiences, perception of place and overall well-being. The new hybrid field of neuroarchitecture offers promising eye-tracking technology and theories for measuring inhabitants’ visual experiences of the city and rethinking the effectiveness of applied design principles across the globe. In this paper, the ‘classic’ design solutions for creating streetscapes on a human scale in densified areas have been assessed by eye-tracking 31 participants in a laboratory setting, all of whom viewed photographs of 15 existing streetscapes in high-rise environments. The study drew on theories from the field of neuroarchitecture and used input from a panel of (landscape) architects and urban designers to design the research and analyze the eye-tracked patterns. The results indicate that the classic design principles (horizontal–vertical rhythms and variety; active ground floor; tactile materials) play a significant role in people’s appreciation of the streetscape and that their attention is unconsciously captured by the presence of these principles. The absence of the design principles seems to result in a scattered ‘searching’ eye movement pattern. This also suggests that a coherent design of streetscapes in high-rise environments may contribute to a human scale at eye-level.
Linear Kalman Filter-Based Grid Synchronization Technique: An Alternative Implementation

Grid synchronization techniques play a significant role in integrating renewable energy sources to the electric power grid. In this context, estimating the phase and frequency of the grid voltage signal is an interesting problem. Out of various techniques available in the literature, linear Kalman filter (LKF) is one of the most popular one. In this article, we propose an alternative implementation of the LKF for grid synchronization application. The proposed implementation uses a linear parametric model of the grid voltage signal including dc offset. It does not involve any quadrature signal generation, rather it works by estimating the phase angle. This helps to estimate the unknown grid frequency directly from the phase angle. This clearly differentiates the proposed alternative implementation with respect to the existing implementations. Performance improvement by the proposed technique is verified extensively through comparative numerical simulation and experimental studies. Comparative results demonstrate the suitability of the proposed technique with respect to other state-of-the-art techniques namely second-order generalized integrator phase-locked loop and enhanced phase-locked loop.
