SEKADAR RENUNGAN

IBU KITA DAN KITA SEBAGAI IBU

1. Setitik air mata ibu jatuh, 10 kebajikan anak hilang,semua ibu jangan jatuhkan air matamu dan jangan  bagi ibumu jatuh air matanya kerana kamu.Biarlah ibu kita menangis kerana anak berjaya bukan menangis angkara perbuatan kita.

2.  Sekiranya kita balik ditengah malam, buka lampu dan tatap muka ibumu, sebab wajah orang yang sedang tidur menampakkan segalanya.

     ADA 3 MATA YANG TIDAK DIJILAT API NERAKA
     *  Melihat kaabah sehingga menitis air mata
     *  Membaca Al-Quran sehingga menitis air mata
     *  Memandang wajah ibu yang sedang tidur / sedar sehingga berlinangan air mata

3.  Orang yang kita kena tengok dan selalu pandang dalam hidup, tengok masa tidur.
     *  Anak
     *  Ibu
     *  Suami / isteri

4.   Adalah menjadi satu dosa jika kita menggunakan jari telunjuk untuk menunjukkan sesuatu pada ibu

5.  Barangsiapa yang tidak mendoakan ibu selepas sembahyang buat ibu yang sudah meninggal maka dikira dia anak derhaka walaupun pada waktu ibunya hidup dia tidak pernah menderhaka. Maksudnya jika ibu masih hidup atau telah tiada, selepas setiap solat kita mesti mendoakannya.

6.  Doa orang yang masih hidup makbul untuk orang yang hidup dan mati. Jadi doakanlah ibu kita yang telah tiada.

7.  Ketika melalui kubur, perlahankan dan beri salam, mereka akan doakan kita " berkatilah si pulan ini ". Jadi jangan lupa beri salam.

8.  Sekiranya ibu kita sudah tiada, bersedekahlah atas namanya, itu yang membuat ibu bahagia disana.

9.  Jika kita sukar untuk bersedekah, bayangkanlah wajah ibu kita, pasti Allah bukakan hati kita untuk bersedekah.

10.  Allah anugerahkan usia yang panjang bagi ibu bapa kita dengan pelbagai kesakitan dan nyanyuk untuk memberi syurga bagi kita. berebutlah menjaga ibu bapa kita, kerana syurga telah dijanjikan untuk kita.

Bersyukurlah kita yang masih mempunyai ibu bapa, sayangilah mereka kerana tanpa mereka kita tiada di bumi ini.......

Sayang makkkk....

Al-Fatihah untuk ayah, agar rohmu ayah bersama orang yang soleh, Amin.

STELLA



INTRODUCTION
First time I know Stella from my lecturer Dr. Azmi which is introducing the uses of stella in learning  and teaching process. Dr Azmi said, we can use the Stella programme to show our progress in work or to show the result when some variables will changes.  We can apply the simulation that contains in stella programme  in our work.  Simulation is the imitation of the operation of a real-world process or system over time. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modeling of natural systems or human systems to gain insight into their functioning. Simulation can be used to show the eventual real effects of alternative conditions and courses of action.
In science education, a computer simulation according to Akpan and Andre (1999) is the use of the computer to simulate dynamic system of objects in a real or imagined world. Computer simulation take many different form from 2 or 3- dimensional simple shapes to highly interactive, laboratory experiment and inquiry environment.

WHAT IS STELLA
STELLA is a flexible computer modeling package with an easy, intuitive interface that allows users to construct dynamic models that realistically simulate biological systems (visit the High Performance System website for more information).  Given the combination of ease of use and modeling power, the STELLA system is ideal to interface with student investigative experiences.   In its most basic form, modeling in STELLA proceeds in three steps:   constructing a qualitative model, parameterizing it, and exploring the model's dynamics.
Stella is the education and research are most exciting when they move out of the lecture hall and library and provide opportunity to create, experience, and see. STELLA® offers a practical way to dynamically visualize and communicate how complex systems and  ideas really work. This system can use in business to improve the way the world works, by creating Systems Thinking-based products that enable people to increase their capacity to think, learn, communicate, and act more systemically.
isee systems is the world leader in Systems Thinking software. Founded in 1985 by Barry Richmond, then a Professor at Dartmouth College the company has grown into a thriving, privately-held corporation with substantial global reach in business, education, and government markets.
Whether they are first-time or experienced modelers, teachers, students, and researchers use STELLA to explore and answer endless questions like:
·         How does climate change influence an ecosystem over time?
·         Would Hamlet’s fate have changed if he’d killed Claudius earlier?
·         How do oil prices respond to shocks in supply and/or demand?
·         What will happen when the ozone layer is gone?
·         How do basic macroeconomic principles affect income and consumption?
STELLA models allow you to communicate how a system works – what goes in, how the system is impacted, what are the outcomes. STELLA supports diverse learning styles with a wide range of storytelling features. Diagrams, charts, and animation help visual learners discover relationships between variables in an equation. Verbal learners might surround visual models with words or attach documents to explain the impact of a new environmental policy. 


We can use Stella in our work that can  help us to:
  • Simulate a system over time
  • Jump the gap between theory and the real world
  • Enable students to creatively change systems
  • Teach students to look for relationships – see the Big Picture
  • Clearly communicate system inputs and outputs and demonstrate outcomes

RESULT
 H1N1 Flu Outbreak
H1N1 (also called “swine flu”) is an influenza virus that first caused illness in Mexico and the United States in March and April, 2009.  Since then, the H1N1 virus has spread from person-to-person worldwide.  In June 2009, the World Health Organization signaled that a pandemic was underway.
With the flu season fast approaching, schools and other organizations are wrestling with policies that will help to minimize the spread of the virus.  This simulation let's you explore the effectiveness of some policy options for a high school population.



Normal view




In normal view, the number of students sick because of infection of diseases increase rapidly from seventh day until  the twenty-eight day.The number of students sick becomes constant start twenty-eight day until the eighty-day. It’s occurs because there are no vaccine use to prevent the H1N1 Flu outbreak .  From the graph , the number of students sick around 608 on 20 days and it becomes rises on the 40 days around 949 person.




          Adjustable

               


From the graph, When percentage added in a vaccine to control of H1N1 flu outbreak, the number of infected students is decreasing. Students who have been infected with the outbreak, which showed a decrease in the twenty-first day, the number of students who were infected decreased from 608 to 50 people only . At the last day , the spread of virus can be control by the vaccine.

Maximun view







Look at the black line upper the x axis. That is the result when we use the maximum vaccine to control the H1N1 flu outbreak. We can conclude that the maximum percentage vaccine use is effective to control the outbreak of H1N1 virus. The number of students infection by the virus decreases and the only 11 person that infected by the virus.
