Most treatment methods for myofascial pain are empirical and aimed at the painful trigger points with the purpose of ablating muscle spasm and restoring normal muscle length. The current study conducted on 72 patients suffering from pain and decreased mouth opening as result of temporo mandibular joint dysfunction. Patients divided into four groups and four treatment modalities used for treatment of myofascial trigger points pain. Results showed that pulsed electromagnetic field is the most effective treatment modality regarding pain relief.
In the real world database contains a large number of attributes and data. The attribute reduction is one of key processes for knowledge acquisition. Attribute reduction or feature selection are employed for dimensionality reduction and intention to select a subset of the unique features of a data set, which have more useful information. A rough set feature selection technique uses the information from both the lower approximation dependency value and a distance metric. It also considers the number of objects in the boundary region and the distance of those objects from the lower approximation. Though it is more efficient in mining, rough set suffers from intensive computation of either discernibility functions or the positive region to find attribute reduction. To overcome the aforementioned problem author of this paper, proposed an attribute subset selection based on the Fuzzy rough set and distance based ranking approach, which works progressively. Attribute reduction, maintain the knowledge base under the principle of the same classification ability to remove irrelevant and redundant attribute properties. Though, it reduces the search space and improves efficiency. Experimental results reveal the efficacy of the adduced methodology as compared to the related works.
The growth in population, urbanization, agriculture, industry and natural occurrences like drought, has increased the demands on South Africa’s limited freshwater resources. For this reason, there is growing interest in alternative water sources. The reuse of greywater (i.e. bath, shower, and laundry effluent) for non-drinking water requirements (such as toilet flushing and landscape irrigation) in high density residences is currently of particular interest to decision-makers. University residences are particularly suitable for greywater reuse as significant volumes of greywater are generated daily, the student residents are often more amenable to non-conventional technologies, greywater reuse for toilet flushing will be hygienically important during periods of intermittent drinking water supply, and university residences are access-controlled and centrally managed (i.e. better control and operation of the reuse system than in buildings devoid of access-control and central management).\n\nThe successful implementation of greywater reuse depends not only on engineering and environmental viability but also on other important factors such as the perceptions and willingness of potential users. In fact, several schemes have failed because decision-makers underestimated or ignored the importance of potential users’ perceptions and willingness to reuse. This paper presents the findings of surveys carried out in three South African universities (the Universities of the Witwatersrand, Johannesburg and Cape Town) using questionnaires. The aim of the surveys was to determine the perceptions of students in the residences of the participating universities and their willingness to reuse greywater for toilet flushing. Specifically, the following were determined and are reported in this paper: attitudes towards the environment, disgust towards reuse (‘yuck’ factor), perceptions of risk associated with reuse, issues of choice, degree of trust in the service provider(s) and willingness to implement reuse.
The following research allows determining the levels of learning and studying strategies from two courses called: Global Competence vs. International Context; form students from a private Mexican university. The application of the inventory L.A.S.S.I. (Learning and study strategies inventory) gives the percentiles of the following areas: attitude, motivation, time administration, anxiety, and concentration, process of information, and selection of principal ideas, help to study, self-evaluation or control and test strategies. According to the “Técnicas Psicométricas, Cát. II - Práctica de Investigación Claves de Corrección” from the “Asociación Iberoamericana de Diagnostico y Evaluación Psicológica (2013)” the range between 30 to 70 in percentiles are considered acceptable, were as the range between 71 to 90 in percentiles are very good for universities students’ with a competitive profile. Even more, those students’ with a range over 90 are considered extraordinary with a high level of achievement and outstanding skills and strategies. With these results, the research team would be able to compare levels of strategies between two courses from the area of humanities, in order to suggest recommendations to increase the level of learning and performance in relation to their learning and study strategies, taking into consideration the nature and structure, in terms of the activities and exercises of each course.
