Authors: - Kuncowati
Published: February 2019

One of the sources of oil pollotion at sea is from ships. This could happen because of ship accidents, tanker ship loading and discharge activities, tanks cleaning and from the ship machinery waste. Crews ship play an important role in preventing and countermeasure oil pollution at sea. International Maritime Organization (IMO) mandated that in education and training seafarers are given material on environmental awareness and pollution prevention at sea. This is meant that seafarers are understood the provisions contained in Marine Pollution (MARPOL) 1973/1978. However, sewage from the engine room and oil tanks or fuel sewage are found from the nearest land that does not meet the provisions in Marpol 1973/1978 Annex I which is very dangerous for marine ecosystems and human. This research was using questionnaire and the respondent was crews ships. This research was using quantitative analysis methods such as multiple linear regression analysis, t test, F test and determination test to know the importance of the crew ship understanding on MARPOL 1973/1978 Annex I and oil pollution prevention drills due to countermeasure oil pollution at sea . Prevention of pollution at the sea also cannot be separated from the monitor and the responsibilities of the government and related parties.

Tsunami is a natural phenomenon that occurs suddenly. This occurs due to tectonic earthquakes, they are fault tectonic earthquake rises and a fault tectonic earthquake downs. The epicenter of the earthquakes is on the seabed with the strength of the earthquake > 6 on the Richter scale. But, the biggest and most dangerous impact of the tsunami is at the port or at the beach. In fault tectonic earthquakes rises is occurs when high waves approach the port and ships that are close to the port or someone who are leaning on the harbor can be blown ashore or even be reversed back to the sea. This could take a lot of casualties. In the other hand, tsunami due to fault tectonic earthquakes downs is occurs the seawater near the beach suddenly receded so that the fish seemed to flounder, which was feared by many fishermen to catch fish, at the interval of 20 minutes came high waves reaching up to 10 m which could took a lot of casualties. The impact of the tsunami on a ship is when she is the middle of the sea then came high wave. The ship can oscillate and if she is a small ship, she can be thrown into the middle of the sea and could be hit by high waves after high waves which could cause accidents or the ship to move towards the port and hit the port or something at the port.

Tsunami merupakan gejala alam yang terjadi secara tiba-tiba, hal ini terjadi disebabkan karena adanya gempa bumi tektonik, yaitu gempa bumi tektonik sesar naik dan gempa bumi tektonik sesar turun. Pusat gempa bumi di dasar laut dengan kekuatan gempa > 6 skala richter. Percobaan bom nuklir di dasar laut, longsoran material di dasar laut dan adanya tsunami disebabkan gempa bumi tektonik di dasar laut. Dampak yang paling besar dan berbahaya akibat tsunami adalah di pelabuhan atau di pinggir pantai. Tsunami akibat gempa bumi tektonik sesar turun. Saat terjadi gempa, air laut dekat pantai mendadak surut sehingga ikan-ikan terlihat menggelepar yang dikhawatirkan banyak nelayan ramai-ramai menangkap ikan, kemudian selang waktu 20 menit datang ombak besar dan tinggi mencapai 10 m sehingga memakan banyak korban jiwa, sedangkan pada gempa tektonik sesar naik gelombang tinggi langsung menuju pantai sehingga korban jiwa juga cukup banyak. Dampak tsunami pada kapal yaitu saat berada di tengah laut gelombang tinggi menghantam kapal, kapal bisa terombang-ambing dan apabila kapal kecil bisa tenggelam. Jika kapal berada dekat pelabuhan, saat terjadi tsunami akibat gempa bumi tektonik sesar turun, kapal akan bergerak ke tengah laut kemudian akan dihantam ombak besar dengan gelombang tinggi dapat menyebabkan terjadinya kecelakaan kapal atau kapal bergerak menuju pelabuhan dan akan menabrak sesuatu yang ada di pelabuhan. Pada gempa bumi tektonik sesar naik, ombak dengan gelombang tinggi akan bergerak ke pelabuhan, kapal yang berada dekat dengan pelabuhan atau yang sedang bersandar di pelabuhan bisa terhempas ke darat dan bahkan bisa terbalik.

GAS SEBAGAI ENERGI ALTERNATIF PADA PENGERAK KAPAL
Authors: Purwanto - , Haryono -
Published: February 2019

Liquefied Petroleum Gas (LPG) usage is liquefied petroleum gas which being melted by adding pressure and lowering the temperature, then the gas will turn into liquid. Butane (C4H10) and propane (C3H8) are the dominating components. The need for Liquefied Petroleum Gas (LPG) especially for the household sector is more effective when using the complement of 3 kg of LPG. Gas fuel for transportations is more suitable when using Compressed Natural Gas (CNG), which is a compressed natural gas as gas fuel. It is considered cleaner and environment friendly than gasoline and diesel fuel because of the gas emissions waste. This CNG is made by compressing methane (CN4) extracted from natural gas then stored and distributed in a pressure pneumatic. Gas for fuel will increase the engine workload, so it tends to increase the consumption of the fuel. However, the gas low pressure on the transportation sector can decrease the compression on the machines. It will reduce the capital up to 50%.

El acceso a la información en la economía de red y su impacto en la industria discográfica
Authors: López Lozano Juana Alejandra
Published: February 2019

La industria discográfica ha visto en el libre acceso a la información –propiciado por la innovación tecnológica- un elemento crucial para suscitar cambios en la manera como el cliente final consume contenidos musicales y los artistas promueven sus creaciones. De esta manera, la revolución tecnológica (que no es nada distinto que la infraestructura empleada para acceder a la información), será la que modifique los modelos de negocio, las estrategias de relación con los públicos y la percepción que tienen de la música los agentes que intervienen en su creación, comercialización y consumo. En este sentido, este artículo de reflexión se propone mostrar cómo el libre acceso a la información, aunque se convirtió en amenaza para el negocio fonográfico, hoy por hoy ofrece oportunidades invaluables para crear valor en los modelos de negocios de la industria discográfica, sustentados en la digitalización y el acceso de contenidos en la web. El artículo se elabora en el marco de la investigación Pasado, presente y futuro de la industria discográfica en Colombia, financiada en 2013 por la Universidad EAN (Bogotá-Colombia), y adscrita a la línea Industria culturales, del grupo de investigación de Cultura y Gestión.
CIBERPOLÍTICA JUVENIL. Entre modos de ser y hacer
Authors: Pérez Morales Flor de Liz
Published: February 2019

¿Cuáles son las motivaciones, generadoras de acción, que provocan en el joven universitario sus prácticas de ciberpolítica? Es arriesgado adentrarse en estos terrenos que pisan la condición estética de la sociedad, sin embargo, la incursión en este mundo creado en la red es también una forma de acercarse al mundo juvenil, y con ello a las figuraciones o transfiguraciones que atraviesa la política como un acto que se lía con las instituciones y sus convenciones. Este germen juvenil que guarda antesala en lo social y político se configura y hace su propio acto; arriba esencialmente como una poética social, expresiones que arrastran consigo sombras del pasado o las evocaciones de un mundo político deseado.

Se advierte en el discurso ciberpolítico de los jóvenes que parecen concebir lo político como el ideal del bien común y la política como la práctica del estado y el sistema social. Los valores se tornan contrarios, en el rango de la confianza y desconfianza de la política. Persiste una noción política que no deja de lado el nacionalismo como esquema motor de lo social, al que se le carga de emotividad, respaldada en el coraje, el amor y la esperanza, triangulación que moviliza el cambio ciudadano.

El artículo es producto de la investigación Imaginarios Juveniles y Prácticas de Ciberpolítica en la Universidad Juárez Autónoma de Tabasco (UJAT) en el que se indagó por la participación en redes que tuvieron los jóvenes universitarios en el marco de las elecciones para gobernador de Tabasco (México) ocurridas en julio de 2012.

A CASE STUDY OF NL INFLUENCE IN UNIS FKIP ENGLISH DEPARTMENT STUDENTS' INTERLANGUAGE
Authors: Sukendra Irmala , Mulyana Agus , Sudarmaji Imam
Published: February 2019

Regardless to the facts that English is being taught to Indonesian students starting from early age, many Indonesian thrive in learning English. They find it quite troublesome for some to acquire the language especially to the level of communicative competence. Although Krashen (1982:10) states that “language acquirers are not usually aware of the fact that they are acquiring language, but are only aware of the fact that they are using the language for communication”, second language acquisition has several obstacles for learners to face and yet the successfulness of mastering the language never surmounts to the one of the native speakers. Learners have never been able to acquire the language as any native speakers do. Mistakes are made and inter-language is unavoidable. McNeili in Ellis (1985, p. 44) mentions that “the mentalist views of L1 acquisition hypothesizes the process of acquisition consists of hypothesis-testing, by which means the grammar of the learner’s mother tongue is related to the principles of the ‘universal grammar’.” Thus this study intends to find out whether the students go through the phase of interlanguage in their attempt to acquire second language and whether their interlanguage forms similar system as postulated by linguists (Krashen).

Towards a new interpretation of Gilmerton Cove – a possible Druid temple?
Authors: Spalding Julian , MacKie Euan W.
Published: February 2019

Gilmerton Cove, a visitor attraction six kilometres south of Edinburgh, has long been thought to be a strange 18th Century underground pub, but Julian Spalding and Euan MacKie think it is much older and dates from the Iron Age. They make the case that it could even be a deliberately buried Druid Temple discovered by chance and dug out 300 years ago and luckily preserved since then. No pre-18th century artefacts have been found in the Cove, but the Cove itself deserves to be interpreted as an extraordinary artefact, for every centimetre of it is man-made.
SOCIAL MEDIA ENTREPRENEURSHIP
Authors: ÇİÇEK Berat
Published: February 2019

Contrary to popular belief,
social media has influenced not only the way of communication among people but
also many different avenues. One of them has been entrepreneurship. By means of
this medium, a new way of doing business has emerged; in view of that, any
individual has the opportunity to do business from where he/she is, without the
need for any structure, any high investment, or any high risk. In this study,
it is aimed to examine this new entrepreneurial phenomenon named as social media entrepreneurship. Thus, how
the social media entrepreneurship differs from some other types of
entrepreneurship has been elaborated, and the problematic of why those
individuals involved in such entrepreneurial activity should be called the
social media entrepreneurs have been accentuated. It is also aimed to present a
model proposal for social entrepreneurs as well as introducing an academic
perspective for this new type of entrepreneurship.

Published: February 2019

El propósito del presente artículo es hacer una revisión actualizada de como la succión digital patológica puede alterar el normal desarrollode la cavidad bucal y presentar alternativas para su interceptación o corrección. La succión digital suele considerarse una reacciónautomática que puede presentarse en momentos de estrés, frustración, falta de atención de los padres y principalmente la falta de unaadecuada lactancia materna ya que conlleva al uso del biberón, que es considerado por varios autores como el agente etiológico principal delhábito de succión no nutritiva. Dentro de las principales características tenemos: Mordida abierta anterior, mordida cruzada posterior unilateral o bilateral, paladar profundo y estrecho, posición lingual baja, dedo con callosidades y de aspecto muy limpio entre otros. El tratamiento debe ser interdisciplinario por lo tanto el equipo deberá estar constituido por el médico pediatra, odontopediatra, fonoaudiólogo, psicólogo, ortodoncista y padres. No se recomienda realizar intervenciones activas en niños menores de tres años por falta de desarrollo cognitivo y emocional. Se realizará primero un tratamiento persuasivo que está basada en comunicación y refuerzo positivo, en caso de no obtener resultados se pasará tratamiento conductual con aditamentos como guantes y si éstos no tienen resultados se utilizara dispositivos ortodónticos que bloquearán el ingreso del dedo y dependiendo de la severidad o dificultad del caso se complementaran con tratamiento miofuncional. Palabras clave: Hábitos orales, succión digital, tratamiento.

AbstractThe purpose of this article is to date as pathological thumb sucking can alter the normal development of the oral cavity and present alternatives for revision or correction interception. The finger sucking is often considered an automatic reaction that can occur in times of stress, frustration, lack of attention from parents and mainly the lack of proper breastfeeding and involved the use of the bottle, which is considered by many authors as the agent main etiological habit of non-nutritive sucking. Among the main features we are: anterior open bite, posterior crossbite unilateral or bilateral, deep and narrow palate, low tongue position, finger calluses and very clean appearance among others. Treatment should be interdisciplinary so the team should be constituted by the pediatrician, dentist, speech therapist, psychologist,orthodontist and parents. It is not recommended active intervention in children under three years for lack of cognitive and emotional development. A persuasive treatment is based on communication and positive reinforcement, if not get results behavioral treatment will happen with attachments such as gloves and if they do not have results orthodontic devices that block the entry of the finger, depending on the severity will be used will be made first or difficulty of the case be supplemented with myofunctional therapy. Keywords: Oral habits, finger sucking, thumb sucking, treatment.

Resting State Functional Connectivity of the Rat Claustrum
Authors: Krimmel Samuel R. , Qadir Houman , Hesselgrave Natalie , White Michael G. , Reser David H. , Mathur Brian N. , Seminowicz David A.
Published: February 2019

The claustrum is structurally connected with many cortical areas.A major hurdle standing in the way of understanding claustrum function is the difficulty in assessing the global functional connectivity (FC) of this structure. The primary issues lie in the inability to isolate claustrum signal from the adjacent insular cortex (Ins), caudate/putamen (CPu), and endopiriform nucleus (Endo). To address this issue, we used (7T) fMRI in the rat and describe a novel analytic method to study claustrum without signal contamination from the surrounding structures. Using this approach, we acquired claustrum signal distinct from Ins, CPu, and Endo, and used this claustrum signal to determine whole brain resting state functional connectivity (RSFC). Claustrum RSFC was distinct from the adjacent structures and displayed extensive connections with sensory cortices and the cingulate cortex, consistent with known structural connectivity of the claustrum. These results suggest fMRI and improved analysis can be combined to accurately assay claustrum function.
Real-time Conflict Resolution Algorithm for Multi-UAV Based on Model Predict Control
Authors: Chen Hao-Xiang , Nan Ying , Yang Yi
Published: February 2019

A real-time conflict resolution algorithm based on model predictive control (MPC) is introduced to address the flight conflict resolution problem in multi-UAV scenarios. Using a low-level controller, the UAV dynamic equations are abstracted into simpler unicycle kinematic equations. The neighboring UAVs exchange their predicted trajectories at each sample time to predict the conflicts. Then, under the predesignated resolution rule and strategy, decentralized coordination and cooperation are performed to resolve the predicted conflicts. The controller structure of the distributed nonlinear model predictive control (DNMPC) is designed to predict potential conflicts and calculate control variables for each UAV. Numerical simulations of multi-UAV coordination are performed to verify the performance of the proposed algorithm. Results demonstrate that the proposed algorithm can resolve the conflicts sufficiently in real time, while causing no further conflicts.
An On-Line and Adaptive Method for Detecting Abnormal Events in Videos Using Spatio-Temporal ConvNet
Authors: Bouindour Samir , Snoussi Hichem , Hittawe Mohamad Mazen , Tazi Nacef , Wang Tian
Published: February 2019

We address in this paper the problem of abnormal event detection in video-surveillance. In this context, we use only normal events as training samples. We propose to use a modified version of pretrained 3D residual convolutional network to extract spatio-temporal features, and we develop a robust classifier based on the selection of vectors of interest. It is able to learn the normal behavior model and detect potentially dangerous abnormal events. This unsupervised method prevents the marginalization of normal events that occur rarely during the training phase since it minimizes redundancy information, and adapt to the appearance of new normal events that occur during the testing phase. Experimental results on challenging datasets show the superiority of the proposed method compared to the state of the art in both frame-level and pixel-level in anomaly detection task.

For this study, we demonstrated three different types of twisted nematic (TN) liquid crystal (LC) terahertz (THz) phase shifters using pristine poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS) thin films as transparent conducting electrodes (TCEs). The transmittance of spin-coated pristine PEDOT: PSS thin film was as high as 92% in the frequency range of 0.2–1.2 THz. This is among the highest reported. Several TN-LC cells were constructed in a comparative study, which confirmed the reliability of pristine PEDOT: PSS as a TCE layer for THz phase shifter applications. The highest phase shift, required root-mean-square (RMS) driving voltage, and threshold voltage achieved by devices tested were 95.2° at 1 THz, 7.2 VRMS, and 0.5 VRMS, respectively. The thickness of the LC layer for the phase shifter was 250 µm, approximately half as thick as previous designs. In addition, the pristine PEDOT: PSS-based TN-LC phase shifter exhibited a figure-of-merit (FOM) value of approximately 6.65 degree·dB−1·V−1. This compared favorably with previously reported homogeneously aligned phase shifters with an FOM of 2.19 degree·dB−1·V−1. Our results indicated that a twisted nematic LC cell with pristine PEDOT: PSS thin films as electrodes is a good combination for a THz phase shifter and wave plates as well as other LC-based THz devices.

Silica optical film specifications are determined by their processing capability and their fabrication stability. Here, a statistical process control (SPC) approach usually used in planar lightwave circuits (PLC) is adopted to analyze the stability of the silica optical film fabrication process. Apart from the raw materials, certain key external factors have to be taken into consideration during the PLC process, such as temperature, relative humidity, process variation and machine aging. The fabrication process can be adjusted according to SPC-based results in real-time, so as to produce high quality silica optical film. By using this method, it is possible to assess the effectiveness of older production lines and extend their production capacity at minimal cost.
Art, Creativity, and the Potential of Artificial Intelligence
Authors: Mazzone Marian , Elgammal Ahmed
Published: February 2019

Our essay discusses an AI process developed for making art (AICAN), and the issues AI creativity raises for understanding art and artists in the 21st century. Backed by our training in computer science (Elgammal) and art history (Mazzone), we argue for the consideration of AICAN’s works as art, relate AICAN works to the contemporary art context, and urge a reconsideration of how we might define human and machine creativity. Our work in developing AI processes for art making, style analysis, and detecting large-scale style patterns in art history has led us to carefully consider the history and dynamics of human art-making and to examine how those patterns can be modeled and taught to the machine. We advocate for a connection between machine creativity and art broadly defined as parallel to but not in conflict with human artists and their emotional and social intentions of art making. Rather, we urge a partnership between human and machine creativity when called for, seeing in this collaboration a means to maximize both partners’ creative strengths.

Published: February 2019

Rhodomyrtus tomentosa (Aiton) Hassk. is a flowering plant belonging to the family Myrtaceae, native to southern and southeastern Asia. It has been used in traditional Vietnamese, Chinese, and Malaysian medicine for a long time for the treatment of diarrhea, dysentery, gynecopathy, stomachache, and wound healing. Moreover, R. tomentosa is used to make various food products such as wine, tea, and jam. Notably, R. tomentosa has been known to contain structurally diverse and biologically active metabolites, thus serving as a potential resource for exploring novel functional agents. Up to now, numerous phenolic and terpenoid compounds from the leaves, root, or fruits of R. tomentosa have been identified, and their biological activities such as antioxidant, antibacterial, anti-inflammatory, and anticancer have been evidenced. In this contribution, an overview of R. tomentosa and its health beneficial properties was focused on and emphasized.

Folded proteins show a high degree of structural order and undergo (fairly constrained) collective motions related to their functions. On the other hand, intrinsically disordered proteins (IDPs), while lacking a well-defined three-dimensional structure, do exhibit some structural and dynamical ordering, but are less constrained in their motions than folded proteins. The larger structural plasticity of IDPs emphasizes the importance of entropically driven motions. Many IDPs undergo function-related disorder-to-order transitions driven by their interaction with specific binding partners. As experimental techniques become more sensitive and become better integrated with computational simulations, we are beginning to see how the modest structural ordering and large amplitude collective motions of IDPs endow them with an ability to mediate multiple interactions with different partners in the cell. To illustrate these points, here, we use Prostate-associated gene 4 (PAGE4), an IDP implicated in prostate cancer (PCa) as an example. We first review our previous efforts using molecular dynamics simulations based on atomistic AWSEM to study the conformational dynamics of PAGE4 and how its motions change in its different physiologically relevant phosphorylated forms. Our simulations quantitatively reproduced experimental observations and revealed how structural and dynamical ordering are encoded in the sequence of PAGE4 and can be modulated by different extents of phosphorylation by the kinases HIPK1 and CLK2. This ordering is reflected in changing populations of certain secondary structural elements as well as in the regularity of its collective motions. These ordered features are directly correlated with the functional interactions of WT-PAGE4, HIPK1-PAGE4 and CLK2-PAGE4 with the AP-1 signaling axis. These interactions give rise to repeated transitions between (high HIPK1-PAGE4, low CLK2-PAGE4) and (low HIPK1-PAGE4, high CLK2-PAGE4) cell phenotypes, which possess differing sensitivities to the standard PCa therapies, such as androgen deprivation therapy (ADT). We argue that, although the structural plasticity of an IDP is important in promoting promiscuous interactions, the modulation of the structural ordering is important for sculpting its interactions so as to rewire with agility biomolecular interaction networks with significant functional consequences.

Published: February 2019

Disposing electronic plastic waste into construction materials is an eco-friendly and energy efficient solution to protect the environment. This work is aimed at enhancing the strength of self-compacting concrete (SCC) replacing sand with electronic waste, namely, High Impact polystyrene (HIPS) plastic granules and cementitious material with fly ash. SCC is designed with the optimized binder content of 497 kg/m3 using Fly Ash (30% by weight of cement) and 0.36 as water-to-binder ratio for all the mixtures. High Impact Polystyrene granules are replaced with sand up to 40% (by volume) at a regular interval of 10%. Rheological behavior is observed with the slump flow test for slump diameter, V-funnel test for flow time, and the L-box test for heights ratio, respectively. Strength behavior is studied by performing split tensile strength, and compressive strength tests after a period of 7, 28, and 90 days, respectively. Both fly ash and HIPS aggregate in addition to SCC up to 30% exhibits a minimal strength reduction with a promising performance in workability. Hence incorporation of both fly ash and HIPS granules up to 30% in SCC is a viable eco-friendly technique, with the beneficial economic impact on the construction industry.

RNASET2 is an extracellular ribonuclease endowed with a marked antitumorigenic role in several carcinomas, independent from its catalytic activity. Besides its antitumorigenic role by the recruitment to the tumor mass of immune cells from the monocyte/macrophage lineage, RNASET2 is induced by cellular stress and involved in actin cytoskeleton remodeling affecting cell interactions with the extracellular matrix (ECM). Here, we aimed to investigate the effects of RNASET2 expression modulation on cell phenotype and behavior in epithelial ovarian cancer (EOC) cellular models. In silico analysis on two publicly available datasets of gene expression from EOC patients (n = 392) indicated that increased RNASET2 transcript levels are associated with longer overall survival. In EOC biopsies (n = 101), analyzed by immunohistochemistry, RNASET2 was found heterogeneously expressed among tumors with different clinical–pathological characteristics and, in some cases, its expression localized to tumor-associated ECM. By characterizing in vitro two models of EOC cells in which RNASET2 was silenced or overexpressed, we report that RNASET2 expression negatively affects growth capability by conferring a peculiar cell phenotype upon the interaction of EOC cells with the ECM, resulting in decreased src activation. Altogether, these data suggest that drugs targeting activated src might represent a therapeutic approach for RNASET2-expressing EOCs.
