Association Rule (AR) mining is a data mining task that discovers interesting relations between variables in databases. The main focus of research in association rule mining is on improving the computational efficiency of mining the rules. The conventional methods available for mining association rules depend on the threshold values of minimum support and minimum confidence. The setting up of these values needs great care and knowledge about the application domain. This paper deals with mining association rules using chaotic Particle swarm optimization (cPSO). Particle swarm optimization (PSO) is simple but powerful population based search technique for solving optimization problems. Chaotic PSO modifies the velocity updation function by introducing chaotic operators derived from chaotic maps. Both PSO and chaotic PSO generate AR with consistency and better computational accuracy when tested on three datasets. The range of attribute values in the dataset is found to affect the performance of the system.

Although quantum mechanics, as one of the most advanced physical theory was successful in explaining many of the physical and natural phenomena and this theory has numerous achievements in diverse areas of human gifted, but parallel to this subject, much confusion has been made in understanding the philosophical principles. The most obvious approach to the challenges of understanding the nature and will cause disagreement and confusion in describing the physical world and reality. The question "how quantum mechanics describes physical reality and describe what results there?" Many researchers have attempted to address the meeting. Among the researchers, David Bohm has a special place. By providing an alternative to quantum mechanics, "Bohemian Mechanics" offers.In this brief article will attempt to introduce "quantum mechanics" and its description of physical reality, the "Bohemian Mechanics" and its own definition of physical reality too.

Talking about green criminology essentially means looking at the position of man in relation to his natural environment. Man by virtue of his position is the epitome of creation. Hence been referred to as the inheritor, conquer and vice glance of the earth. In search of better life, man was able to manipulate his natural environment by any means available to him; this has cause a lot of havoc to him, his environment and other living and non-living beings. The methods and means used to explore the environment are seen by many as necessary tools for advancement, this has dated back from the very beginning of man existence on earth surface. However as man continue to advance in his quest and achievements there comes the alarms as to the consequence of this adventure called ‘development”. The price to pay for this development includes the very sacrifice of man’s life, health and that of other living and non-living beings of the natural environment. The critical question here is does this achievements really worth the price? Who are those paying the price? Who benefit from this high price? And could this falls under acts that calls for legal attention and what are the legal remedies put in place to control these acts? Is there other alternative ways to explore nature thereby inflicting less harm? These and many other questions is what this research work seeks to answer.

Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations, It occurs because dry land ecosystems are extremely vulnerable to over exploitation and inappropriate use. Land degradation is a major obstacle militating sustainable use of land resources for agriculture. The relative role of climate, drought and human impact was discussed. This menace which manifested in the forms of soil erosion, desertification, salting of river and ponds, acidification and Stalinization, loss of soil fauna and flora e.t.c. is seriously militating productive parts of the soil, Poverty, political instability, deforestation over grazing and bad irrigation practices also undermine the land's fertility, thus, resulted in a negative effect on the socio-economic status of the inhabitants. These consequences can be properly addressed through the establishment of shelterbelts and woodlots, improvement of agricultural productivity, creation of awareness of the drought-hazard through provision of necessary resources for meteorological services in the area as well as legislation against indiscriminate felling of trees.

Students’ satisfaction has become an essence of success in today’s highly competitive world. In service industry specifically the education industry, communication is vital to determine students’ satisfaction. Past researches indicated that, most meaning of conversational messages comes from non-verbal communication. Evaluation on students’ perception on lecturers’ kinesics that would lead to their satisfaction to the services provided was examined. The results of the study illustrate that kinesics that is also known as body movements was shown to have the most impact on students’ satisfaction. Therefore, from this study, it can be inferred that students’ in Malaysian universities are mostly observant on the body movements used, facial expression and postures and gestures of the body of their lecturers when lectures are delivered to them. The present study caters for a wide spectrum of students and development professionals, especially those who are interested in non-verbal communication specifically kinesics-related issues. It is highly hoped that the information gleaned from the present study may assist all service employees specifically in understanding better, the importance of kinesics and its effects on students’ satisfaction.

The neurosarcoïdosis, is a rare granulomatosis, which causes serious neurological troubles. Until today, there is no consensus about its diagnosis. The stereotaxic biopsy appears to be the gold standard, for histological and definitivel diagnostic of this pathology. Our goal is to show through a case report the importance of the STB, in definitive diagnostic of cerebral granulomatosis; The case is about a young adult, who had clinical neurological disorders, going through an experimental therapeutic, and shows complications, and the STB corrects the diagnosis, so that without this gesture, the patient should have died.

Face recognition recently plays an important role in many application areas such as: commercel, politic, and security. That’s why recognition and high recognition rates of them is very important. features extraction ,decrease of extracted features dimentions and classify are three major and important in the face recognition systems, in the project, we apply third level of gabor wavelet transform for compress and features extraction, also, we apply principle component analyse(PCA)for dimention decrease of extracted features at extremity, we use radial basis function network(RBFN)for classify and recognition this proposal system performs on the ORL face database. This system results average correct recognition percent 97.75% on ORL database.

In recent decades, drought events caused many adverse effects on humans and environment, notably in arid and semi-arid regions of the world. This many worsen the desertification process and throw away many opportunities. Several droughts have been occurred in Sistan plain south eastern Iran, and the most recent one (1999-2006) said to be the worst drought in the past 600 years and has much negative environmental, economical and social effects. In this study, changes of vegetation cover was assessed using the pre and past drought data. After interpreting the results, it was found that quantity and quality of plants reduced by 100% and that much of changes occurred in abandoned lands. Moreover, it was discovered that the main causes of plant cover desertification are natural factors and human factor of mismanagement.

A quality teacher can control and make a realization of all the skills, knowledge and expertise in himself as a practical instrument for enhancing the effectiveness of teaching in the workshop. This research aims to identify the skills of teachers in school. Teachers need to show that they have skills in doing practical work, workshop management, teaching and conducting skills of the teaching aids. This means that teachers need to have high skills in the teaching practice. The problems faced by the teacher to teach life skills in school subjects to be dealt with, especially involving practical work in workshops. Study instrument used is Inquisition of which has 40 items. Sample studies that involved in this study consisted of 30 teachers of Muar Vocational High School. The data that is derived processed by using SPSS (Statistical package for Social Sciences) version 11.5 for Windows. The results of the analysis is stated in the form of statistics and the frequency, percent minimum value and show teachers Muar Vocational High School have the skills to do the works in the high skills, management skills workshop, teaching and also control teaching aids. This means that teachers need to have high skills in the teaching practice. From the data obtained as a whole found the teachers of Muar Vocational High School have high skills in practical teaching of Living Skills subject.

In this paper we developed new matrices (angle matrix ,connection matrix and connection angle matrix) in addition to a set of matrices (adjacent matrix, incidence matrix) that previously used to introduce the mathematical representation of high-resolution protein structures an accurate representatin that facilitate analysis of its structures.
