Some New Cauchy Sequence Spaces
Authors: Polat Harun
Published: December 2018

In this paper, our goal is to introduce some new Cauchy sequence spaces. These spaces are defined by Cauchy transforms. We shall use notations $C_{\infty }\left( s,t\right) $, $C\left( s,t\right) $ and $C_{0}\left( s,t\right) ~$for these new sequence spaces. We prove that these new sequence spaces $C_{\infty }\left( s,t\right) $, $C\left( s,t\right) $ and $C_{0}\left( s,t\right) ~$ are the $BK-$spaces and isomorphic to the spaces $l_{\infty }$, $c\ $and $c_{0}$, respectively. Besides the bases of these spaces, $\alpha -$, $\beta -\ $and $\gamma -$ duals of these spaces will be given. Finally, the matrix classes $(C\left( s,t\right) :l_{p})$ and $(C\left( s,t\right) :c)$ have been characterized.

The results indicate that Galerkin method is effectively implemented. It is seen that results are compatible with exact solutions and consistent with other existing numerical methods.
The geopolitical change in the east sea (from the post-cold war until now)
Authors: Vo Sen Van , Nguyen Trung The
Published: December 2018

After Vietnam War and especially the disintegration of the Soviet Union (1991), a “geopolitical vacuum” has appeared in the East Sea. However, the East Sea has not become a geopolitical dispute of the world after a long time. In recent years, after the settlement of hot spots in the Balkans, the Middle East, Central Asia,... and the rise of China, there has been an increase in the East Sea’s geopolitical status. The U.S. has declared its interest in this region. The geopolitics of the East Sea has attracted the attention of many countries all over the world. At the same time, it has also had great influence on the strength, the status and the foreign policy of countries like the U.S., China, Japan, India, Russia and the ASEAN community. When controlling the East Sea, China can break the “siege” of the U.S. and other countries near the East Sea, control the second busiest sea lane in the world, enhance its power and political status. This means that Japan, Russia and India will be surpassed by China in the “Eurasian chessboard”. Thus, there would be so many changes in the complexion of the world. The U.S. concern stems from the rise of China, the freedom of navigation, the U.S. allies and the U.S. unique status. ASEAN Community fears “the claims” of China - a major power trying to extend its power from “regional” to "worldwide". It can be said that just from a regional matter, the geopolitics of East Sea has become a global one. This paper will clarify that geopolitical change.
The maritime defense activities under the Nguyen dynasty (1802-1884)
Authors: Tran Mai Thi
Published: December 2018

The Emperor Minh Mang once affirmed: “The governance of nation should focus on ethical practice and danger-matter consideration. These two things are indispensable. Now I conduct copper-shipbuilding, take advantage of the important coastal areas to build plants, preserve those ships when needed”. Not only Emperor Minh Mang but the Nguyen Emperors from Gia Long to Thieu Tri and Tu Duc were highly aware of the country’s territorial waters defense. The Nguyen Dynasty’s marine considerations including the monitoring and defending were expressed through practical activities: building a strong navy, developing maritime defense systems; promulgate regulations like “tuan duyen chuong trinh”, “tuan thuyen quy thuc” and “tuan duong xu phan le”… The maritime defense activities under Nguyen Dynasty (1802-1884) and the lessons learned from these activities will help us “know the past, find the future” and acquire insightful practical values also.

Authors: Nguyen Luc Tien
Published: December 2018

Recently, China has shown her strong expansionism in East Sea while The US also expresses her determination of implementing the “coming back to Asia” policy. In that context, Japan openly expresses the concerns and actively establishes its role in solving the issues of East Sea. The recent move of Japan is not a single move but in a series of strategic policies of Japan in order to ensure maritime security of Japan as well as restrain the expansionism of China. ASEAN countries such as Vietnam and the Philippines give a cheerful reception toward this move of Japan and hope that Japan can play an active role and more effective in resolving the issue of East Sea dispute. This paper will clarify the following issues: 1. The concern of Japan toward the East Sea Dispute and the move of Japan in the issue. 2. Expectation of ASEAN countries and the world about the role of Japan in resolving the East Sea dispute. 3. From Japan’s perspective of its maritime policy and international relationship strategy, particularly the relationship with the US, China, and ASEAN, the paper will examine whether Japan can meet the expectations of ASEAN countries and the world in resolving the issue of East Sea Dispute.

Published: December 2018

Over the years, record keeping was done manually, keeping paper-based documents of all students’ academic information. This system however has proven inefficient because it could not cater for unforeseen circumstances like fire accident, house demolishing or even the most obvious one - the student’s record going missing. Researchers have come up with more effective ways of solving the paper problem, which led to several web-based student information management systems. However, these researchers did not fully eradicate the paper problem because the process still required an initial printing, then scanning of academic records which served as inputs into the system. Also, there was an increase in the occurrence of service unavailability because all storage and processes came from the same location, making the server vulnerable to unforeseen circumstances like power outage, loss of network connection and system malfunction. This research work however aims at implementing an E-transcript management system using blockchain technology, which is capable of eliminating the paper problem whilst ensuring that users experienced service uptime round the clock.

Toddler development stage is an important thing to always follow-up. A child is not the same as a miniature adult. Small children are still experiencing a process of growth and development. These two processes are important for the child's future in terms of physical and brain development. Delays or abnormalities at the stage of toddler development can have a negative impact on the toddler. This is the reason why knowing the stage of toddler development becomes a very important thing. Monitoring toddler development can be more practical by utilizing a combination of technology between microcontroller control and database usage as a result of monitoring. Monitoring conducted on toddlers can include monitoring the development of body weight, monitoring body temperature, and monitoring the toddler's heart rate. This microcontroller can process data generated by load cell, temperature sensor and heartbeat sensors to be processed and displayed in real time using the web with a MySQL database. Users who have logged in can access data on the development of body weight, body temperature, and heart rate of toddlers with good and organized records wherever and whenever. So that toddler development can be known easily. Designing a monitoring system for toddler development using a microcontroller that is integrated with the MySQL database at the Posyandu Pian Raya Kabupatem Musi Rawas can be a good solution so that toddler development data can be controlled and accessed anytime.

Abstract

Satisfaction is a feeling of pleasure or disappointment that comes from the compatibility between the impression of performance (results) a product with his hopes. Service is an activity that has several intangible elements associated with it, what involves several interactions with consumers or customers with property in their ownership, and does not result in ownership transfers.

The thing that must be considered in providing services to consumers is listening to the voice of consumers so that the company must obtain feedback some consumer responses regarding facilities and infrastructure related to services provided to consumers for control and measures of success of a company itself, this also requires companies to develop strategies to overcome competition in order to become the primary choice of customers.

Однією з проблем на сьогодні є організація керованої евакуації людей з будівель за необхідний час, що розраховується, виходячи з їх об'ємно-планувальних рішень. Під час моделювання руху людей, які апроксимуються набором еліпсів, виникає задача їх щільного розміщення з різною локальною щільністю, яка виникає в зв'язку з урахуванням різних мінімально допустимих відстаней між еліпсами. Дотримання таких відстаней викликане урахуванням низки обмежень, серед яких можна виділити рух людей із різною швидкістю, урахуванням їх маневреності, комфортності тощо. В роботі запропонована математична модель задачі оптимізації розміщення еліпсів в частині обліку норм і технологічних обмежень на параметри розміщення об'єктів, що дозволило представити задачу моделювання руху людей, які апроксимуються еліпсами, у вигляді задачі геометричного проектування. Розроблено метод математичного моделювання переміщення еліпсів в однозв'язній області за критерієм максимуму сукупного їх переміщення з урахуванням різних, по заданим технологічним обмеженнями, мінімально допустимих відстаней між ними, що дозволило розширити клас розв'язуваних актуальних практичних завдань.

Published: December 2018

Дана робота присвячена вирішенню задачі декомпозиції системи управління стабілізацією координат морського судна. У статті розглянуто питання побудови математичної моделі судна, як динамічного об'єкта в полі сил, що збурюють, отримано узагальнену модель об'єкта і його декомпозицію. Сучасні технології і зачі мореплавання висунули задачу позиціонування суден. Розширення обсягу роботи на шельфі, обслуговування платформ і оперативні роботи вимагають точного позиціонування при значному хвилюванні. Виникає все більше додатків динамічного позиціонування (ДП), з'являються нові класи судів для цих додатків, а самі системи ДП стають більш масовими і дешевими. Таким чином, актуальна розробка методів і засобів підвищення точності позиціювання. В роботі показано, що дана задача відноситься до задач з розподіленими параметрами, а модель судна має другий порядок. Поставлено завдання аналізу методів регулювання використовуваних для динамічного позиціонування. Не дивлячись на значні зусилля розробників і велику кількість реалізованих проектів, досягти тривалого утримання судна при хвилюванні в заданій позиції не вдається. Причиною цього є не лише брак енергоозброєності використовуваних судів. Численні дослідження в області розвитку систем регулювання поки не дають очікуваного результату. Виходячи з ситуації, що склалася, в статті зроблено спробу аналізу методів побудови систем регулювання і розробки алгоритму точного позиціонування судна при енергії хвилювання, що не перевищує енергоозброєності об'єкта (судна). В результаті проведеного дослідження були зроблені наступні висновки: 1) задача динамічного позиціонування є задачею з розподіленими параметрами; 2) опис судна, як об'єкта регулювання, являє собою диференціальне рівняння в приватних похідних другого порядку; 3) декомпозиція задачі регулювання координат плаваючого засобу дозволяє виділити окрему підсистему динамічного позиціонування; 4) з огляду на те, що використання сучасних методів регулювання не дозволяє створити системи здатні довго зберігати необхідну точність позиціонування, потрібен аналіз використовуваних методів регулювання.

Authors: Bellen Joy , Jomoc Amalia
Published: December 2018

Research shows that cognitive and affective abilities among science students can be enhanced using peer tutoring approach. However, peer tutoring approach remains an underutilized peer support (Bond & Castagnera 2006). This study determined the effects of peer tutoring approach in motivation, participation and academic performance of grade 8 students. Using regression discontinuity design, the respondents were non-struggling, struggling who accepted peer tutoring and struggling students who declined peer tutoring. Results showed that struggling students who accepted peer tutoring showed better participation, expert like perceptions of junior high school science, and exam performance relative to their peers who were not attending the peer tutoring sessions. The results of this study provide evidence to teachers who want to plan targeted peer support for students who are struggling in junior high school science.
Extracellular Enzymes and Antimicrobial Activities of Celluloytic Bacteria from the Gut of Black Surgeonfish (Acanthurus gahhm)
Authors: Legario Francis , Pesina Agile
Published: December 2018

The diverse microflora of the gastrointestinal tracts of fish is a promising frontier for the discovery of beneficial bacteria and further microbiological investigations. Isolation, characterization, and determination of the enzymatic and antibacterial activities of the culturable cellulolytic bacteria from the gut of Acanthurus gahhm(black surgeonfish) were investigated. The bacterial strains were isolated from the three gut regions (anterior, mid and hind) using minimum medium. The isolates were characterized morphologically, biochemically and physiologically using standard methods. The isolates were qualitatively tested for activities of extracellular enzymes such as in amylase, protease and lipase. Results showed that the cellulolytic bacteria were Grampositive bacilli, coccobacilli and cocci exhibiting varied biochemical activities most notably fermentative abilities. Physiological tests revealed that the bacteria were able to tolerate high salt concentration.The strains exhibited varying levels of activities for protease and lipase but not on amylase. The isolates were further tested for their antibacterial activity and only one isolate, AG 5H showed signs of efficacy through a zone of inhibition against S. aureus but not for E. coli. The isolate AG5H is interesting because of its high level of enzymatic activities and antibacterial action, which can be exploited for further study for fish health and nutrition and other industrial applications.

Authors: Rallos Roland , Asio Victor , Villamayor Faustino
Published: December 2018

Studies on soil-landscape relationships are necessary to improve our understanding of the spatial distribution and variation of soils for their sustainable management. This study evaluated the relationship between soil properties and landscape position in the northern volcanic mountain of Leyte, Philippines. Five soil profiles located on summit, shoulder, backslope and footslope positions were evaluated. Findings revealed that the degree of soil development as well as the soil morphophysical and chemical properties varied with landscape position. The soil in the most stable position (summit) had thicker solum and slightly more developed soil profile than the soils in other landscape positions. On the other hand, soils in the unstable position (backslope) generally had thinner solum. All the five soils also revealed the influence of the andesitic volcanic parent material on their properties. They all showed some properties typical of Andisols such as low bulk density and high pH in NaF although they were classified as Andic Dystrudept. The soils all possessed physical and chemical constraints for crop production.
Assessing the Microlevel Impacts of Sin Tax Law on Cigarette Consumption: A Case Study for Mahaplag, Leyte, Philippines
Authors: Preciados Lemuel , Carcajente Jayson
Published: December 2018

Examined in this study were the effects of Sin Tax Law at the microlevel. Using the before-and-after method of analyzing impacts, we applied a multiple regression analysis incorporating difference-in-difference approach of econometric estimation. It appeared that youths had significantly lower cigarette consumption after the implementation of this law. This suggests that Sin Tax Law (STL) discouraged the youth from smoking. In contrast, consumption of cigarettes among adults did not change significantly implying that the tax induced price-increase was relatively less effective. Therefore, it is recommended that there should be specific policies targeting adult smokers to inhibit them from consuming more cigarettes. Results also provide important lessons for future research in monitoring and evaluating public policies.
Online measurement of bulk, tensile, brightness, and ovendry content of bleached chemithermomechanical pulp using visible and near infrared spectroscopy
Authors: Tomkins Matthew , Gilbert Wesley , Trung Thanh
Published: December 2018

Current pulp mill practice to determine the pulp properties of bleached chemithermomechanical pulp (BCTMP) is to prepare and test handsheets for properties of interest. While the use of handsheets is well established, tests require well trained technical staff and introduce a significant lag before test results can be acted upon. In this report, a prototype online visible and near infrared (Vis-NIR) sensor that complements handsheet testing was trialed for 16 months at a BCTMP mill. The system consists of a cabinet located near a probe installed on a conveyor belt between a slab press and a bale press. When a bale stops on the conveyor belt, the probe rises and comes into contact with the bale, taking a spectral measurement and predicting its bulk, tensile strength, brightness, and ovendry (o.d.) content. The data presented here covers a period of 100 days of real-time measurements that correlated with laboratory tests with an R2 of 0.88 for bulk, 0.87 for tensile, and 0.92 for brightness. Bulk, tensile strength, and brightness measurements had root mean square error of prediction (RMSEP) values of 0.19 cm3/g, 3.994 Nm/g, and 0.96 brightness points, respectively. Ovendry content measurements trended with the mill’s existing online moisture measurement system and had an R2 of 0.36 and an RMSEP value of 1.04%. The quality of the correlation for o.d. content was substantially impacted because of difficulties with synchronizing the time stamps between the mill’s existing online measurements and the online system reported here. The online Vis-NIR sensor provides information in real time and has the potential to be used to reach target grade properties more quickly, assist in the identification of inefficient chemical dousing, reduce the effect of operator bias during testing, allow for the prioritizing of laboratory tests, and improve segregation of final products according to customer needs. However, further development would be necessary to use these measurements as part of a process control strategy.
Use of vent stack temperature as a feedforward variable for dissolver total titratable alkali (TTA) control
Authors: Ren Wei , Dubord Brennan , Johnson Jason , Allison Bruce
Published: December 2018

Tight control of raw green liquor total titratable alkali (TTA) may be considered an important first step towards improving the overall economic performance of the causticizing process. Dissolving tank control is made difficult by the fact that the unknown smelt flow is highly variable and subject to runoff. High TTA variability negatively impacts operational costs through increased scaling in the dissolver and transfer lines, increased deadload in the liquor cycle, under- and over-liming, increased energy consumption, and increased maintenance. Current practice is to use feedback control to regulate the TTA to a target value through manipulation of weak wash flow while simultaneously keeping dissolver density within acceptable limits. Unfortunately, the amount of variability reduction that can be achieved by feedback control alone is fundamentally limited by the process dynamics. One way to improve upon the situation would be to measure the smelt flow and use it as a feedforward control variable. Direct measurement of smelt flow is not yet possible. The use of an indirect measurement, the dissolver vent stack temperature, is investigated in this paper as a surrogate feedforward variable for dissolving tank TTA control. Mill trials indicate that significant variability reduction in the raw green liquor TTA is possible and that the control improvements carry through to the downstream processes.
Effects of lignin chemistry on oxygen delignification performance

Published: December 2018

The present work focused on characterizing the chemical and structural properties of isolated lignin from six hardwoods and their kraft pulps in an attempt to better understand the relationship between lignin’s chemical properties and resultant oxygen delignification performance. Several hardwood samples were cooked under the same conditions with varying alkali charges to obtain unbleached pulps with kappa numbers between 19 and 20. These pulps were then subjected to an oxygen delignification stage. Both processes were evaluated for pulp quality, residual lignin, and O-stage delignification efficiency. The oxygen delignification stage was carried out under fixed conditions and evaluated with regards to kappa number, which was corrected for hexenuronic acid (HexA) contributions.Results revealed that different hardwood species exhibited differing oxygen delignification efficiencies. A high correlation was found between the O-stage delignification efficiency and the content of phenolic groups in the unbleached lignin, which confirmed that free phenolic groups are the reactive site for molecular oxygen attack. When different hardwood species were compared, the HexA contents were not found to affect O-stage delignification efficiencies.
Tecendo Fios Entre o Feminismo Latino-Americano Descolonial e os Estudos Pós-Coloniais Latino- Americanos
Authors: SARTORE ANNA RITA , Santos Aline Renata dos , Silva Camila Ferreira da
Published: December 2018

O presente trabalho tem por objetivo realizar aproximações epistemológicas entre o Feminismo Latino-americano Descolonial, Curiel, (2009); Mohanty, (2008); Paredes, (2010); Espinosa-Miñoso, (2014, 2013), e os Estudos Pós-coloniais Latino-americanos Dussel, (1994); Quijano, (2000, 2005); Mignolo (2011); Porto-Gonçalves, (2009). Utilizamo-nos da pesquisa bibliográfica e da Análise de Conteúdo via Análise Temática Bardin, (2011), Vala (1986). As aproximações epistemológicas do Feminismo Latino-americano Descolonial com os Estudos Pós-Coloniais Latino-americanos ocorrem na medida em que questionam o lócus de enunciação de conhecimento eurocêntrico e suas formas de produção prescritas como válidas e universais e apontam para a valorização e a legitimação de outros loci de enunciação que produzam conhecimentos outros. O entrelaçamento destas abordagens permite-nos compreender as mulheres latinas americanas como protagonistas de lutas políticas e epistêmicas na construção e na constituição de uma sociedade despatriarcalizada.
Educação Contextualizada e Relações Étnico-Raciais a partir da Lei 10.639/03: Desafios aos Professores e ao Sistema de Ensino de Juazeiro/BA
Authors: Reis Edmerson Santos , Santos Antônio Carvalho dos Jr , Alves Rafael Santana
Published: December 2018

Neste artigo problematizamos a necessidade de se fazer conhecer a lei 10.639/2003 entre os professores da rede municipal de ensino do município de Juazeiro-BA, haja vista que ela está em vigor desde 2003. Articulamos a relação entre Educação Contextualizada e referida lei, acreditando que este é um passo importante para desconstruirmos o racismo institucionalizado nas escolas, e que se operacionaliza nos currículos. Desse modo, partimos da ideia de um currículo que se faz politicamente na construção de representações; currículo enquanto lugar de disputa, povoado por relações de poder. Sendo o currículo um campo de ação, acreditamos que podemos disputá-lo a partir de posturas que se assentam na perspectiva intercultural, que se orientam por meio do diálogo com os contextos diversos. Com isso, analisamos dados construídos a partir de entrevistas realizadas com docentes da rede Municipal de Ensino. Objetivamos com isso, verificar o grau de conhecimento dos entrevistados acerca da lei 10.639/03. Os dados evidenciam o significativo número de entrevistadosque desconhece a lei, sinalizando fragilidades e/ou não mobilização institucional para efetivação desse marco legal na rede municipal de ensino.

Em seu terceiro número, a revista Interritórios, periódico da área de Educação, traz algumas questões que, ao longo dos tempos,  demandaram respostas de pesquisadores das Ciências Humanas. Com os temas, vieram, a reboque, os dilemas, as angústias e as delícias de pensar-se o sujeito. Como não poderia deixar de ser, o conhecimento é o epicentro e dele emana o insistente desejo que captura os cientistas, desde sempre.
La expansión (auto)biográfica: Territorios habitados y sentidos desocultados en la investigación educativa.
Authors: PORTA Luis , AGUIRRE Jonathan , RAMALLO Francisco
Published: December 2018

En este texto proponemos reflexionar en relación a la expansión y las potencialidades de la dimensión (auto)biográfico-narrativa en la investigación en educación, a partir de la experiencia del Grupo de Investigaciones en Educación y Estudios Culturales de la Universidad Nacional de Mar del Plata. En particular nos ocupamos de relatar cómo, cada vez con mayor profundidad, dicha dimensión comenzó a habitar nuestras investigaciones. Para ello reconocemos que en esta comunidad académica, en los últimos años, se instaló a la perspectiva narrativa no sólo como una metodología cualitativa que permite reconocer aspectos sensibles y ocultos de la educación, sino sobre todo, se la identifica como otro modo de conocer, constituido por el desocultar de una primera persona. Esta mirada, si se quiere radicalizada en relación al modelo clásico de ciencia, la interpreta más allá de lo metodológico y reflexiona sobre los aspectos políticos, pedagógicos, epistemológicos y ontológicos de nuestros relatos. Y más aún tiene una vocación que ofrece la posibilidad de interrogarse acerca de ¿qué hacemos con los relatos? y ¿qué es lo que hacen los relatos con nosotros? Autobiografías. Educación.

Novas práticas pedagógicas: considerações sobre transformações escolares a partir da atuação de docentes do Núcleo Takinahakỹ
Authors: NAZARENO Elias
Published: December 2018

Desde o início do processo de colonização do Brasil, aproximadamente em 1532, a educação escolar indígena foi considerada como estratégica para o projeto de colonização e subalternização dos povos indígenas brasileiros. Não por acaso, essa tarefa foi delegada às ordens religiosas, sobretudo à jesuíta, pois elas detinham, além do monopólio em relação à produção do conhecimento e sua divulgação, o poder espiritual, por meio do cristianismo, e a chancela, por parte do Estado português, para que atuassem de forma uníssona com os interesses políticos, econômicos e expansionistas desse Estado. Temos, assim, dois pilares básicos em tal projeto de colonização: a educação escolar, com base nos valores ocidentais, e a cristianização ou catequização dos povos indígenas. New pedagogical practices: considerations about school transformations based on the work of teachers of the Takinahaky Nucleus

The purpose of this activity was to empower fishing communities in Kalibaru, Cilincing through introducing knowledge of food handling and processing technologies, especially green mussels-based products. The partner involved in this study was the Annisa Bakti Business Group having 15 members of single parents. The profession of family members was green mussels peeler. Peeling process performed was through boiling, peeling the shell, icing, and then selling. The handling of green mussels with peeling was mainly intended to solve the problem overproduction which was not absorbed by the market as life green mussels. The appearance of peeled green mussels were usually pale, and the peeler usually introduced synthetic dyes to make them more attractive. The types of dyes used are generally not allowed for food because they are harmful to health. Based on those facts, the community empowerment efforts were carried out through the following ways: (1) Building motivation to develop the business; (2) More hygienic handling of green mussels; (3) Training on oyster (mussels) sauce processing; (4) Development of processed mussels product business, through introducing simple business feasibility study, business management, and simple financial bookkeeping.  The program is expected to have an impact on improving the welfare of partners, especially the Annisa Bakti. Business Groups.

Published: December 2018

Waste Banks is an alternative waste management in Indonesia. Waste Bank at RPTRA Maneuver is one of the Waste Banks that has been established in Kecamatan Kembangan. Qualitative research is used to see the effectiveness of waste management in the RPTRA Maneuver from the perspective of the aspect of waste management. There are still many obstacles experienced by the community to be able to process waste into selling or worthy materials. During this time, community participation has been good enough, but not optimal. This is because knowledge and understanding are not evenly distributed. Operational engineering aspects have been running effectively but place constraints are the main problem.

Authors: عبد السلام ايهاب
Published: December 2018

It is well-known that the existence of outliers in the data will adversely affect the efficiency of estimation and results of the current study. In this paper four methods will be studied to detect outliers for the multiple linear regression model in two cases :  first, in real data; and secondly,  after adding the outliers to data and the attempt to detect it. The study is conducted for samples with different sizes, and uses three measures for  comparing between these methods . These three measures are : the mask, dumping and standard error of the estimate.
