Sensitive Ants for Denial Jamming Attack on Wireless Sensor Network

A new defence mechanism for different jamming attack on Wireless Sensor Network (WSN) based on ant system it is introduced. The artificial sensitive ants react on network attacks in particular based on their sensitivity level. The information is re-directed from the attacked node to its appropriate destination node. It is analyzed how are detected and isolated the jamming attacks with mobile agents in general and in particular with the newly ant-based sensitive approach.Comment: - 4 pages - accepted pape

The student attention in physical education classes

In the direction to look for a better Knowing of the teaching process, to the level of that we cannot see: the thought, and particulary, the thought of those to which the learning concerns, we direct our study for the attention of the pupils. In fact, it seems not to be doubt that, in education, if the pupils will not be with attention to what they are doing, their learning will leave inevitably compromised. The basic purpose of this research was to know what students were thinking during Physical Education Classes. For data collection we used an instrument with a single question of closed and alternative reply, so that it could be filled in the fastest way. The questionnaire was applied to a large group of 10-13 years old pupils, in the classes observed to pré-service physical Education Teachers. The analysis of the questionnaires allowed us to get a global image of this aspect of the thought of the pupils, to be able to represent the profile of their attention in the lessons of the human movement

Doktrin Ultra Vires dan Implikasi Penerapnnya dalam Undang-Undang Nomor 40 Tahun 2007 tentang Perseroan Terbatas

Ultra vires berasal dari bahasa Latin yang dalam bahasa Inggris di terjemah kansebagai“beyond the power”atau dalam bahasa Indonesia diterjemahkan melampaui kewenangan. Dalam kepustakaan hukum, ultra vires sering kali disebutjuga sebagai extra vires, karena extra vires juga memiliki makna yang sama dengan ultra vires yaitu beyond the power atau melampaui kewenangan. Jika sebuah perusahaan melalui upan bidang usaha yang ditetapkan dalam Anggaran Dasar perusahaan atau badan hukum yang dimaksud, maka perusahaan tersebut dikategorikan telah melakukan perbuatan yang dimaksud sebagai ultra vires. Dengan demikian doktrin ultra vires menegaskan bahwa Perseroan tidak dapat melakukan kegiatan diluar apa yang diamanatkan dalam Anggaran Dasar Perseroan tersebut(intra vires). Pengaturan norma-norma ultra vires dalam UU No. 40 Tahun 2007 tentang Perseroan Terbatas (UUPT) dapat ditemukan dalam pembatasan kewenangan yang diberikan pada organ-organ Perseroan. Bahwa yang dimaksud organ dalam Perseroan Terbatas dalam undang-undang yaitu Rapat Umum Pemegang Saham (RUPS), Direksi dan Dewan Komisaris vide Pasal 1 angka 2 UUPT.Penerapan doktrin ultra vires dapat ditelusuri lebih lanjut dalam pemaknaan substansi pengaturan dan penerapan doktrin ultra vires atau sering kali dalam praktik dikenal sebagai“The Ultra Vires Rule”dalam UUPT dan dalam praktik peradilannya putusan Mahkamah Agung menjadi penting untuk menjelaskan maksud pengaturan norma dalam undang-undang serta konsistensinya dalam penerapan dalam bidang Hukum Perseroan di Indonesia. Mahkamah Agung dengan putusan-putusannya sebagai mana telah dipaparkan tersebut berfungsi sebagai lembaga yang menciptakan unifikasi, menjalankan reformasi dan melaksanakan pengawasan terhadap peradilan dibawahnya. Putusan Mahkamah Agung ternyata menegaskan bahwa doktrin ultra vires dianut dalam pengaturan norma dan penerapannya dalam Hukum Perseroan di Indonesia. Dalam pembuatan Akta Pendirian Perseroan yang dilakukan dihadapan Notaris sesuai amanat Pasal 7 ayat (1) UUPT, pembatasan-pembatasan tanggung jawab dan kewenangan masing-masing organ Perseroan yang bersifat ultra vires harus di jelaskan kembali oleh Notaris selaku pejabat penegak hukum perdata, agar para pendiri dan organ Perseroan memahami kedudukan dan tanggung jawabnya masing, serta pembatasan-pembatasan dilakukan terhadap kewenangan tersebut baik dalam Anggaran Dasar maupun dalam UUPT karena semua pelangaran terhadap pembatasan kewenangan tersebut dapat berakibat pada tuntutan perdata maupun pidana oleh pihak-pihak yang dirugikan

Postural patterns in the first year of life: contributions of maternal physical activity in the pregnancy period

BACKGROUND: The study objective was intended to verify whether the practice of maternal physical activity during the pregnancy period could be assumed as a contribution to the acquisition of postural patterns in the child during its first year of life. METHODS: A transversal and descriptive study was carried where we recorded the developments observed in a sample of 80 Portuguese children, according to the habits and type of physical activity of the mothers. Statistical descriptive and inferential test were performed. RESULTS: The results were clearly positive in terms of temporal gains of neck tonic control, and also in the acquisition of an erect position. CONCLUSIONS: Despite the average values are not statistical significant we have observed indicators that the maternal physical activity during pregnancy apparently is a factor that can favor the child’s motor development during their first year of life, particularly in the acquisition of postural patterns.info:eu-repo/semantics/publishedVersio

La atención de los estudiantes durante la clase de educación física basada en el rendimiento académico

Attention is an important variable that can dictate the success and failure of an activity or task. This variable is characterized by the ability to direct cognitive resources to a given situation. The purpose of this research was to find patterns in the students’ attention profiles, according to their academic achievement, during the physical education class and in different sports. We used the ATEST-EF questionnaire (Petrica, 2010) in which students had to answer the question «What were you thinking the moment you heard the signal?» The study involved 156 students from the 3th cycle of basic education, aged between 12 and 16 years old ( = 14,7 ± 1,3) evaluated in four different sports taught in the discipline of physical education (athletics, gymnastics, basketball and football), and in four moments of the class. Considering our variables, we used Chi-Square and Kruskal-Wallis statistical tests. The results show that task attendance holdsthehighestpercentagevalues throughouttheclassinrelationtotheremainingcategories,regardlessoftheiracademicperformance and sport, but we observed that students with satisfactory and good academic performance have more stable values of attention regarding the students with less academic performance. We found statistical significance at the end of the class between students with good academic performance and affective attention, and among students with lower academic performance and attention to other things. Subsequently, we used the same classification to compare the profiles of attention among the four mentioned sports. We observed some patterns between team and individual sports, but did not find statistically differences, however the results suggest a positive relationship between attention and academic performance.La atención es una variable importante que puede dictar el éxito y el fracaso de una actividad o tarea. Esta variable se caracteriza por la capacidad de dirigir recursos cognitivos a una situación dada. El propósito de esta investigación fue encontrar patrones en los perfiles de atención de los estudiantes, de acuerdo con sus logros académicos, durante la clase de educación física y en diferentes deportes. Utilizamos el cuestionario ATEST-EF (Petrica, 2010) en el que los estudiantes tenían que responder la pregunta «Qué estaba pensando en el momento en que escuchó la señal?» En el estudio participaron 156 estudiantes del tercer ciclo de educación básica, con edades comprendidas entre 12 y 16 años (= 14,7 ± 1,3) evaluados en cuatro deportes diferentes que se imparten en la disciplina de educación física (atletismo, gimnasia, baloncesto y fútbol), y en cuatro momentos de la clase. Considerando nuestras variables, utilizamos las pruebas estadísticas Chi-Square y Kruskal-Wallis. Los resultados muestran que la asistencia a las tareas tiene los valores porcentuales más altos en toda la clase en relación con las categorías restantes, independientemente de su rendimiento académico y deporte, pero observamos que los estudiantes con un rendimiento académico satisfactorio y bueno tienen valores de atención más estables con respecto a los estudiantes con Menos rendimiento académico. Encontramos significación estadística al final de la clase entre estudiantes con buen rendimiento académico y atención afectiva, y entre estudiantes con bajo rendimiento académico y atención a otras cosas. Posteriormente, utilizamos la misma clasificación para comparar los perfiles de atención entre los cuatro deportes mencionados. Observamos algunos patrones entre el equipo y los deportes individuales, pero no encontramos diferencias estadísticas, sin embargo, los resultados sugieren una relación positiva entre la atención y el rendimiento académico.info:eu-repo/semantics/publishedVersio

Classical hybrid approaches on a transportation problem with gas emissions constraints

In order to keep a green planet, in particular its important to limiting the pollution with gas emissions. In a specific capacitated fixed-charge transportation problem with fixed capacities for distribution centers and customers with particular demands, the objective is to keep the pollution factor in a given range while the total cost of the transportation is as low as possible. In order to solve this problem, we developed several hybrid variants of the nearest neighbor classical approach. The proposed models are analyzed on a set of instances used in the literature. The preliminary results shows that the newly approaches are attractive and appropriate for solving the described transportation problem.Comment: 4 pages, 1 figur
