Published: July 2019

Berdasarkan data dari Badan Kesehatan Dunia WHO (World Health Organization), menyebutkan 1 dari 10 kematian pada orang dewasa disebabkan karena merokok dimana rokok ini membunuh hampir lima juta orang setiap tahunnya. Menurut situs Computer Media Learning, Perokok pasif adalah orang-orang yang tidak merokok, namun menjadi korban perokok aktif karena turut mengisap asap sampingan (di samping asap utama yang dihembuskan balik oleh perokok).Melihat data, ini kita perlu selidiki berapa persen pengetahuan siswa tentang bahaya merokok bagi kesehatan tubuh mereka sendiri. Penelitian ini dilakukan pada 102 anak . Data diambil dengan mengunakan kuesioner dan dengan pengambilan data secara langsung yaitu dengan wawancara. Data dianalisis menggunakan analisis bivariat menggunakan uji chi kuadrat. Dalam penelitian menunjukkan bahwa sebenarnya anak memiliki tingkat pengetahuan yang tinggi tentang bahaya merokok bagi kesehatan mereka, seperti efek samping dari bahaya merokok jangka pendek, dan jangka panjang.Minuman beralkohol adalah minuman yang mengandung etanol. Etanol (CH3CH2OH) adalah bahan psikoaktif dan konsumsinya menyebabkan penurunan kesadaran. Penelitian ini adalah penelitian kuantitatif dengan metode observasional analitik, desain yang digunakan adalah cross sectional. Variabel penelitian meliputi rasa kurang percaya diri, rasa ingin tahu atau cobacoba, pelarian dari suatu masalah, pengetahuan, faktor keluarga, lingkungan tempat tinggal, pendidikan. Hasil penelitian menunjukkan bahwa penyalahgunaan alkohol dan merokok pada remaja. Kesimpulannya yaitu faktor rasa kurang percaya diri, rasa ingin tahu atau coba-coba, pelarian dari masalah, pengetahuan yang kurang, keluarga yang buruk, lingkungan yang buruk signifikan meningkatkan adiksi atau kecanduan pada remaja.
Fees and governance: Towards sustainability in water resources management at schools in post-apartheid South Africa
Authors: Booysen MJ , Wijesiri Buddhi , Ripunda Cheroline , Goonetilleke Ashantha
Published: July 2019

Water scarcity is increasingly staking a claim next to energy as a threat to the sustainability of large cities, especially in developing countries with limited resources. The recent crisis brought on by Cape Town’s “Day Zero” drought created the impetus to expand on existing research on water demand management to include analysis of school usage patterns and key determinants thereof. With the effects of apartheid still visible in society and in school infrastructure coupled with the high water usage rates at schools, this paper evaluates the impact of school affluence (whether it is fee-paying or not, and self-governing or not) on water usage. We find that poor schools use substantially more water, partially because of poor maintenance, with mean water efficiencies of poor schools around 50% and 80% for affluent schools. Bayesian models were used to further determine which characteristics of a school are good proxies for the higher usage to help administrators and policy makers in the resource constrained educational environment. In addition to the obvious impact of maintenance, the results point an incriminatory finger at early morning-school usage, early afternoon usage, and Saturday usage
The eLoaD platform endows centrifugal microfluidics with on-disc power and communication
Authors: Delgado Sarai M. Torres , Korvink Jan G. , Mager Dario
Published: July 2019

In this paper we present a comprehensive description of the design, fabrication and operation of an electrified Lab-on-a-Disc (eLoaD) system. The smart platform is developed to extend conventional Lab-on-a-Disc applications with an electronic interface, providing additional flow control and sensing capabilities to centrifugal microfluidics platforms. Wireless power is transferred from a Qi-compliant transmitter to the eLoaD platform during rotation. An Arduino-based microcontroller, a Bluetooth communication module, and an on-board SDcard are integrated into the platform. This generalises the applicability of the eLoaD and its modules for performing a wide range of laboratory unit operations, procedures, or diagnostic assays, all controlled wirelessly during spinning. The lightweight platform is fully reusable and modular in design and construction. An interchangeable and non-disposable application disc is fitted with the necessary sensors and/or actuators for a specific assay or experiment to be performed. A particular advantage is the ability to continuously monitor and interact with LoaD experiments, overcoming the limitations of stroboscopy. We demonstrate the applicability of the platform for three sensing experiments involving optical, electrochemical, and temperature detection, and one actuation experiment involving controlled heating/cooling. The complete electronic designs and example programming codes are extensively documented in the supplementary material for easy adaptation.

Korupsi di Daerah Indonesia yang Dilakukan oleh Pemerintah Daerah
Authors: rosmini natalia
Published: July 2019

Indonesia merupakan salah satu negara terkaya di Asia dilihat dari keanekaragaman kekayaan sumber daya alamnya. Tetapi ironisnya, negaratercinta ini dibandingkan dengan negara lain di kawasan Asia bukanlah merupakan sebuah negara yang kaya malahan termasuk negara yang miskin. Mengapa demikian? Salah satu penyebabnya adalah rendahnya kualitas sumber daya manusianya. Kualitas tersebut bukan hanya dari segi pengetahuan atau intelektualnya tetapi juga menyangkut kualitas moral dan kepribadiannya. Rapuhnya moral dan rendahnya tingkat kejujuran dari aparat penyelenggara negara menyebabkan terjadinya korupsi. Korupsi di Indonesia dewasa ini sudah merupakan patologi social (penyakit social) yang sangat berbahaya yang mengancam semua aspek kehidupan bermasyarakat, berbangsa dan bernegara.

This article describe about Administration of School and Community Relations is an entire process of activities planned and tried intentionally and seriously and continuous guidance to get sympathy from the public in general and from the public in particular, so that school operational activities / education are more effective and efficient to help achieve predetermined educational goals. School attendance is based on the willingness of both the state and the people who support it. Therefore people who work in schools inevitably have to work with the community. The community here can take the form of parents, agencies, organizations, both public and private. One reason why schools need support from the community where the school is located is because the school must be funded. The school assignment here is how to foster a sense of belonging and a sense of being partially responsible for the community towards the school.A
FILSAFAT MORAL-CINDYEP-32318406
Authors: cindyeka
Published: July 2019

Tema tatanan moral subjektif langsung memaksudkan subjektifitas dari suatu perbuatan.Hanya apabila suatu perbuatan memiliki karakter subjektif perbuatan tersebut masuk dalam kualifikasi moral. Perbuatan manusia itu tidak tunggal, melainkan kompleks karena komplesifitas perbuatan manusia, penilaian moralnya juga kompleks. Mengenai perbuatan manusia, kita bisa membedakan antara Volition (Kehendak) dan Perwujudannya (Action). Volition berarti kehendak dalam artian tegas yang dapat masuk dalam kualifikasi baik buruk secara moral, dan Action memaksudkan eksekusi atau penentuan kehendak yang kita tampilkan dibawah kontrol kita.Antara kehendak (Volution) dan perwujudannya (Action) memang tidak bisa dipisahkan apabila suatu tindakan manusia dapat disebut sebagai tindakan lengkap. Tetapi keduanya bisa dibedakan.Menurut teori hati nurani. Hati nurani pertama-tama menyentuh pengetahuan (atau kesadaran). Hati nurani berarti hati manusia mmemiliki pengetahua. Hati nurani ialah hati yang mengetahui. Sebenarnya proporsi “hati yang mengetahui” sama sekali tidak tepat.

A generalized framework for classical test theory
Authors: Foster Robert
Published: July 2019

This paper develops a generalized framework which allows for the use of parametric classical test theory inference with non-normal models. Using the theory of natural exponential families and Bayesian theory of their conjugate priors, theoretical properties of test scores under the framework are derived, including a formula for parallel-test reliability in terms of the test length and a parameter of the underlying population distribution of abilities. This framework is shown to satisfy the general properties of classical test theory several common classical test theory results are shown to reduce to parallel-test reliability in this framework. An empirical Bayes method for estimating reliability, both with point estimates and with intervals, is described using maximum likelihood. This method is applied to an example set of data and compared to classical test theory estimators of reliability, and a simulation study is performed to show the coverage of the interval estimates of reliability derived from the framework.
Maze Made Easy: Better and easier measures of incremental processing difficulty
Authors: Boyce Veronica , Futrell Richard , Levy Roger Philip
Published: July 2019

Behavioral measures of incremental language comprehension difficulty form a crucial part of the empirical basis of psycholinguistics. The two most common methods for obtaining these measures have significant limitations: eye tracking studies are resource-intensive, and self-paced reading can yield noisy data with poor localization. These limitations are even more severe for web-based crowdsourcing studies, where eye tracking is infeasible and self-paced reading is vulnerable to inattentive participants. Here we make a case for broader adoption of the Maze task, involving sequential forced choice between each successive word in a sentence and a contextually inappropriate distractor. We leverage natural language processing technology to automate the most researcher-laborious part of Maze -- generating distractor materials -- and show that the resulting A(uto)-Maze method has dramatically superior statistical power and localization for well-established syntactic ambiguity resolution phenomena. We make our code freely available online for widespread adoption of A-maze by the psycholinguistics community.
Dynamic internal states shape memory retrieval
Authors: Tarder-Stoll Hannah , Jayakumar Manasi , Dimsdale-Zucker Halle R. , Gunseli Eren , Aly Mariam
Published: July 2019

Why do we sometimes easily retrieve memories, but other times appear to forget them? We often look to our external environment for retrieval cues, but another way to optimize memory retrieval is to be in a mental state, or mode, that prioritizes access to our internal representation of the world. Such a ‘retrieval mode’ was proposed by Endel Tulving (1983), who considered it a neurocognitive state in which one keeps the goal of memory retrieval in mind. Building on Tulving’s proposal, we review converging evidence from multiple lines of research that emphasize the importance of internal states in the instantiation of retrieval modes that optimize successful remembering. We identify three key factors that contribute to a retrieval mode by modulating either the likelihood or the content of retrieval: (1) an intention to remember or forget (either in the present or the future), (2) attentional selection of goal-relevant memories and suppression of distractors, and (3) fluctuating levels of acetylcholine in the hippocampus. We discuss empirical evidence that these internal states individually influence memory retrieval and propose how they may interact synergistically. Characterizing these dynamic internal factors is an important key for unlocking our understanding of the organization and accessibility of our memories.

La enfermedad cerebrovascular es un problema de salud pública mundial, considerada dentro de las primeras causas de mortalidad. La trombosis venosa cerebral (TVC) es una de sus patologías, que a pesar de ser infrecuente puede llevar a severas complicaciones en el paciente. Es por eso que se presentan dos casos de infartos bitalámicos secundarios a trombosis venosa cerebral profunda, con hallazgos clínicos e imagenológicos inusuales que hicieron aún más difícil su diagnóstico. Debido a las diferentes funciones que posee el tálamo además de la infrecuencia de la trombosis venosa cerebral profunda, la presentación clínica sigue siendo atípica y es usual que se consideren otros diagnósticos al inicio del evento, por lo tanto, consideramos importante proyectar estudios con muestras de mayor tamaño para definir con claridad la clínica y los hallazgos radiológicos de esta patología.

Jaringan Pesantren di Jawa Barat Tahun 1800-1945: Critical Review atas Disertasi “Jaringan Pesantren di Priangan 1800-1945” Karya Ading Kusdiana
Authors: Fauzan Pepen Irpan , Fata Ahmad Khoirul
Published: July 2019

Pesantren as subcultures are indeed interesting to be studied. Several studies have been carried out such as Zamakhsary Dhofier on the network of pesantren in Java and Martin van Bruinessen on the pesantren and tarekat. Continuing it, Ading Kusdiana through her dissertation at Padjadjaran University conducted a research on the network of Pesantren in the Priangan region (West Java), focusing on the existence and conti­nuity of Pesantren through five inter-Islamic networks: scientific networks, marriage, genealogical, congregational religious views, and the similarity of the vision of opposition to the invaders. Kusdiana's research confirmed Zamakhshari Dhofier's theory and did not refute it at all. So that this feels like a new work with a sense of "old work". The study of this theme will be even more interesting if Kusdiana uses the new genealogical theory as Yudi Latif did. This will also portray changes and continuity in the network of Pesantren. However, Kusdiana’s work deserves to be appre­ciated because it presents a lot of new data-information regarding the traces and spreads of Pesantren in Priangan. Through thiswork, we can get a relatively completed picture of the world of Pesantren in Priangan in the 1800-1945 period.Keywords: Network of Pesantren, Genealogy Theory, Pesantren in Priangan Pesantren sebagai subkultur memang menarik dikaji. Beberapa kajian telah dilakukan seperti Zamakhsary Dhofier tentang jaringan pesantren di Jawa dan Martin van Bruinessen tentang pesantren dan tarekat. Melanjut­kan keduanya, Ading Kusdiana melalui disertasinya di Universitas Padjadjaran melakukan penelitian jaringan pesantren di wilayah Priangan (Jawa Barat), dengan titik-fokus pada proses eksistensi dan kesinam­bungan pesantren melalui lima bentuk jaringan antarpesantren: jaringan keilmuan, perkawinan, genealogis, kesamaan pandangan keagamaan tare­kat, serta kesamaan visi penentangan terhadap penjajah. Namun penelitian Kusdiana ini meneguhkan teori Zamakhsyari Dhofier dan sama sekali tidak melakukan penyanggahan terhadapnya. Sehingga ini terasa sebagai karya baru dengan rasa “karya lama”. Kajian terhadap tema ini akan semakin menarik jika Kusdiana menggunakan teori genealogis baru seperti yang dilakukan Yudi Latif. Ini sekaligus akan memotret perubahan dan kontinuitas dalam jaringan pesantren yang dikajinya. Namun demikian, karya Kusdiana ini layak diapresiasi karena menyajikan banyak data-informasi baru terkait jejak dan sebaran-pertumbuhan pesantren di Priangan. Melalui karya Kusdiana ini, kita bisa mendapatkan gambaran relatif utuh terkait dunia pesantren di Priangan pada periode 1800-1945.Kata Kunci: Jaringan Pesantren, Teori Genealogi, Pesantren di Priangan

Published: July 2019

The molecular weight of poly[acrylamide-co-vinylpyrrolidone-co-(vinyl benzyl) trimethyl ammonium]chloride is determined from numerical and experimental data of the reduced viscosity of polymer in brine (with 0.1M NaCl) at normal temperature and pressure. The methodology is based on the numerical results of the mean radius of gyration of polymer and reduced viscosity which is derived from the molecular dynamics simulation of the mixture by using the NPT ensemble. The formula of the reduced viscosity as a function of the polymer radius of gyration and the polymer concentration in brine is proposed.

A charged perfect fluid model with high compactness
Authors: Estevez-Delgado G. , Estevez-Delgado J. , Pineda Duran M. , Montelongo García N. , Paulin-Fuentes J.M.
Published: July 2019

A relativistic, static and spherically symmetrical stellar model is presented, constituted by a perfect charged fluid. This represents a generalization to the case of a perfect neutral fluid, whose construction is made through the solution to the Einstein-Maxwell equations proposing a form of gravitational potential  $g_{tt}$ and the electric field. The choice of electric field implies that this model supports values of compactness$u=GM/c^2R\leq 0.5337972212$, values higher than the case without electric charge ($u\leq 0.3581350065$), being this feature of relevance to get to represent compact stars. In addition, density and pressure are positive functions, bounded and decreasing monotones, the electric field is a monotonously increasing function as well as satisfying the condition of causality so the model is physically acceptable. In a complementary way, the internal behavior of the hydrostatic functions and their values are obtained taking as a data the corresponding to a star of $1 M_\odot$,for different values of the charge parameter, obtaining an interval for the central density $\rho_c\approx (7.9545,2.7279) 10^{19}$ $ Kg/m^3$ characteristic of compact stars.

Authors: Meira Filho D. P. , Dos Santos de Sausa G. , Silva de Souza L. Helena , De Silva Sales R. , Santos Kamassury J. Kysnney , Ferreira Lopes And J.
Published: July 2019

In this paper we will use classical field theory to address the interaction of an accelerated point source with a non-massive Klein-Gordon-Fock (KGF) field in Minkowski spacetime. For this, initially, we obtain the KGF equation for the non-massive scalar field via lagrangian formalism and the scalar potential through Green's function formalism. Finally, we reach the expression of the power radiated by a point scalar source under the influence of this field and its covariant generalization.
Motion of a rolling sphere on an azimuthally symmetric surface
Authors: Marín Quiroz D. M.
Published: July 2019

This paper analyzes the translational motion that a sphere rolling over an azimuthally symmetric surface, under the presence of a constant gravitational field, and with the rolling-without-slipping condition, exhibits in two different situations: with and without friction with air, where the latter is expressed as a power-series function of the sphere’s translational speed. In order to achieve this, the equations of motion for each case are obtained through the use of Lagrangian Mechanics and are subsequently solved by numerical computation in Wolfram Mathematica. For the frictionless case, periodic behavior and a conservation law for the angular coordinate have been found, along with the condition under which an effective potential energy can be approximated as well as the relationships between initial conditions that produce gravitational-like trajectories for the motion of the sphere. The equations of motion derived for the case with friction are found to predict the energy loss and general decay of the sphere’s motion. Likewise, the normal force over the sphere as a function of time is obtained through the method of Lagrange's Undetermined Multipliers, and thus, the general conditions that the motion must satisfy in order to be described by the obtained models. Overall, this research provides insight into the type and characteristics of the motion performed by the system in these two cases, both through equations and their numerical solutions for different surfaces and initial conditions.
Una imagen dice más que mil palabras: Una sencilla actividad experimental para representar gráficamente la fuerza de roce
Authors: Vásquez Vergara A. , Bussenius Cortada W. , Pinochet And J.
Published: July 2019

Como es sabido, la fuerza de roce estático depende de las fuerzas aplicadas, mientras que la fuerza de roce cinético es constante e independiente de dichas fuerzas. Gráficamente, esto significa que la relación entre fuerza de roce y fuerza aplicada es una recta ascendente para el caso estático, y una recta horizontal para el caso cinético. Esta situación, que se estudia teóricamente en todos los cursos introductorios de mecánica newtoniana, tanto en educación secundaria como superior, pocas veces es analizada experimentalmente con los estudiantes. En este trabajo se presenta un sencillo experimento que permite obtener una gráfica roce vs fuerza aplicada que se encuentra en excelente acuerdo con la gráfica teórica (esperada) que aparece en la mayor parte de los textos de estudio de física.

El “Test of Understanding of Graphs in Kinematics (TUG-K)”, es el test de opciones múltiples más importante diseñado hasta la fecha para evaluar el entendimiento de estudiantes universitarios en gráficas de cinemática. En este estudio se presenta una modificación significativa de este test en español. El test fue implementado en 124 estudiantes que terminaban un curso de mecánica basado en cálculo en una universidad privada mexicana. Los cuatro objetivos del presente artículo son: (1) presentar el test en español y su proceso de rediseño, (2) mostrar que es un instrumento de evaluación confiable con poder discriminatorio adecuado, (3) exponer un análisis detallado del entendimiento de los estudiantes en los conceptos evaluados en el test, y (4) establecer recomendaciones específicas, basadas en los análisis previos, para la instrucción de estos conceptos. De esta forma, este artículo ofrece un análisis exhaustivo de dificultades de entendimiento, recomendaciones basadas en investigación y un examen disponible en el apéndice que pueden ser empleados por investigadores del área de la enseñanza de la física, y por profesores que enseñen el tema de gráficas de cinemática en cursos de física en países hispanohablantes.   The “Test of Understanding of Graphs in Kinematics (TUG-K)”, is the most important multiple-choice test designed to date to evaluate the understanding of university students in kinematics graphs. In this study, we present a significant modification of this test in Spanish. We administered the test to 124 students who finished a mechanics-based course in a private Mexican university. The four objectives of this article are: (1) to present the test in Spanish and its redesign process, (2) to show that it is a reliable evaluation instrument with adequate discriminatory power, (3) to present a detailed analysis of students’ understanding on the concepts evaluated in the test, and (4) to establish specific recommendations, based on the previous analyzes, for the instruction of these concepts. In this way, this article offers a comprehensive analysis of understanding difficulties, research-based recommendations and the test available in the Appendix that can be used by researchersin the field of physics education, and by teachers who teach the subject of graphics of kinematics in physics courses in Spanish-speaking countries.
Análisis de un oscilador no lineal utilizando el método de Euler en una planilla de cálculo
Authors: Suárez A. , Tornaría And F.
Published: July 2019

Se analizan teórica y experimentalmente las oscilaciones unidimensionales no lineales de un imán que está unido a un resorte e interactúa con un grupo de imanes. Se resuelve numéricamente la ecuación de movimiento del sistema utilizando el método de Euler en una planilla de cálculo. Experimentalmente, la evolución temporal de la posición se obtiene mediante análisis de video. La correspondencia entre las predicciones del modelo y los datos experimentales deja en evidencia la potencialidad de las herramientas utilizadas. La sencillez de la propuesta presentada permite su aplicación en los primeros cursos universitarios de Física experimental.
Dynamics for an electric pendulum
Authors: Aguilar-Loreto O. , Muñoz A. , Jiménez Pérez And A.
Published: July 2019

The Lagrangian formulation has been an extensive tool for the analysis of physical systems. In particular, we have applied the Lagrangian procedure to deduce the dynamics and stability for an electric pendulum system. We have considered two cases, a repulsive and attractive electric interactions as perturbations to the classical simple pendulum model. We study both cases, the repulsive and attractive electric interactions that can be considered as perturbations to the classical simple pendulum model. We have contrast both situations studying their restrictions, phase trajectories and stability points for this purpose.
Primer texto mexicano sobre Radioactividad y Física Atómica
Authors: Moreno  Corral M. A.
Published: July 2019

Literature about physical sciences has always been scarce in our country,but even more so before its professionalization among us. For this reason, itis remarkable the existence of the book Compendio de los fen´omenos de laRadioactividad y nociones sobre la Constituci´on de la Materia, published inMexico City in 1932, in which they were treated with certain amplitude thosesubjects, so it turns out to be of some importance to those who investigatethe development of Physics in this nation. This work, written by the engineerJuan Mateos, was not a translation to Spanish of a book written in anotherlanguage elsewhere, but it is an original contribution in our language of itsauthor, which is relevant, because it shows the early existence of Mexicanswho were aware, at least in general, of the main advances in the research toestablish the nature of matter. In this article, a summary of the materialdealt in this pioneer book is given, because we consider that it sheds lighton the initial efforts to understand matter made in our nation, and to makeknown this new field for its research in Physics in our country.

Discriminatory Customary Practices Against Women’s Rights: An Account Of Intervention Strategies By Southern African Developing States
Authors: Raji Barakat Adebisi , Akolokwu Grace Ogonda
Published: July 2019

Discriminatory customary practices against the protection of gender rights still thrive in many Southern African developing states despite domestic and international legal regimes to prevent them. These practices were borne out of customary inclinations of the patriarchal social system in most African communities, which hold women and the girl-child in perpetual subordination to the male. In other words, the African customary systems wrongly perceive the male gender as being naturally superior to the female. More so, the loopholes in the executive and legislative efforts to combat human rights abuses as well as judicial pronouncements and governmental apathy in eradicating abuses against gender discrimination towards women in the Southern African developing states are apparent. Consequently, discriminatory customary practices continue to thrive despite legislative framework protecting gender rights in the states. The methodology adopted in this paper is a doctrinal approach, which places reliance on legal materials that are enacted and enforced by African Developing states. The article examines international and states laws, norms, institutions, international and national publications and other international legal instruments relating to gender discrimination. Most importantly, the central attention of this study focuses on the discriminatory customary practices against women in the Southern African Developing States. The current study finds that, despite  identifiable discriminatory customary practices which are still practised and condoned as being the lifestyle and tradition of groups are criminalized and declared abhorrent by specific domestic legislation of nations, the human rights of the girl-child and women continue to be in chains and fetters. In conclusion, this article advocates increased advocacy, judicial activism and more proactive legislative action that protect women and the girl-child in the Southern African developing states.
The Adequacy of Existing Support Systems in Addressing the Issue of Teenage Pregnancies in Malaysia: A Legal Response
Authors: Mohd Nor Aishah , Mohd Zin Najibah , Che Soh Roslina
Published: July 2019

This article examines the adequacy of the current support systems in addressing the issue of teenage pregnancies in Malaysia. This study was conducted primarily through a doctrinal study of existing literature such as articles, journals and reports related to the current issues encountered by the pregnant teenagers. There is also a non-doctrinal method carried out whereby the researchers had conducted fieldwork interviews with the government department, non-government organisations (NGOs) and social activist on the efforts done in addressing the problem. Due to the lack of a specific policy on teenage pregnancies in Malaysia, there have been concerns on issues related to the rights of these teenagers to education during pregnancy; criminal issues on abortion, infanticide and child sexual grooming; child marriages and the lack of support from parents, family members and the society for care, motivation, healthcare and preparation for motherhood among these teenagers. The findings establish the current support system is inadequate to meet the contemporary needs of pregnant teenagers. It is suggested that a comprehensive legal framework for teenage pregnancies in Malaysia needs to be put in place. These can include legislating necessary laws and policies, which can be more effective through integrated services and proper monitoring and enforcement in order to meet the current needs of the targeted group.
