Introduction to IPv6


Size of IPv4 is 32-bits only, while IPv6 is 128-bits and it is represented in hexadecimal numbers in the form of X.X.X.X.X.X.X.X which X consists of 16-bit value. Example expression of IPv6 is 2000:0000:1234:ABCD:0000:0000:FACE:00006. This can be written as 2000:0:1234:ABCD:0:0:FACE:0006 or simplified to 2000::1234:ABCD:::FACE:6. If we find the address is 2000::A, it is also can be written as 2000:0:0:0:0:0:0:000A.

            Let’s take a look at this example of CIDR X:X:X:X:X:X:X:X/64. It means that the network is 64-bit, and we can calculate like Figure 1, and hence we get N.N.N.N.H.H.H.H. IPv6 does not have broadcast and network address translation (NAT). However, similar to IPv4, IPv6 has unicast and multicast. IPv6 is faster because of no broadcast. It can access anywhere, and everyone gets public IP. The differences between IPv4 and IPv6 are summarized in Table 1. We will discuss further the range of global unicast, link-local and multicast in the next volume.

Table 1 IPv4 vs IPv6

Global unicast 2000::/3
Private IP
Link local FE80::/10
Loopback 127.0.0.0 => 127.255.255.255
::1
Multicast 224-239
Multicast FF00::/8


IPv6 can be anycast i.e. one to nearest. Same IPv6 can be assigned to many hosts. Refer to the Figure 2, if we are in Malaysia and we do not have the server in Malaysia, we can anycast to the nearest, and it is Singapore server.

Living for Work. Is It Worth It?

Written by Nur Idawati Md Enzai

Long gone the days where a normal job revolves around 9-5 working time. Constant availability for communication, no thanks to Internet, has made the situation becomes worse. In the good old days, if you are on leave, you really could rest and don’t have to think about work. As technology has enabled us to become contactable 24-7, our bosses and colleagues could endlessly shove job after job under our very nose day and night. This could seriously affect the work life balance negatively.

Most European countries have been seriously implementing healthy work-life balance after realizing its importance. Australia and New Zealand have also jumped into the bandwagon by giving a particular attention on the work-life balance. Shorter working weeks and hours have been adopted as it is believed to help the staffs wellbeing and happiness [1]. Fun fact, even though working hours have been shortened, these countries still thrive economically. Having experienced living in Australia for a few years, I personally witnessed most Australians working really hard during the day, resting with family and friends at night, spending time with family and friends during weekends. Even the shopping malls are closed early during the weekends. A friend’s husband was told off by his boss for working on a weekend. “Don’t you have a family?” his boss asked. A university official even jokingly told the graduate students, “I don’t want to see you Asian scholars at the university on weekends.”

Asian countries are especially guilty when it comes to working long hours. Japan has always been known for long working hours and little to none vacation. True, it is a developed country, and yet the suicide rates are among the highest. Cases of death due to overwork has become quite common as well. Therefore, the government of Japan has been seriously looking into this problem, even though back in the 70s and 80s there was apparent denial that death could be caused by overwork. However, the relationship between overwork and death has been accepted by Japanese corporate lawyers and government officials [2].

I believe that the reason Asian countries tend to have more working hours, could be due to culture of saving face and hierarchy. Leaving early while the others are still at work may make an Asian feeling guilty even though he/she has finished work.  Asians are generally taught to keep their opinions to themselves to avoid conflict, compared to a Westerner who typically doesn’t care what the others think. I remember, a friend from China once told me that on Chinese New Year, some of them don’t even go back to their hometown. Chinese New Year which is supposed to be their number one celebration is not even in their priorities. It makes me afraid to imagine their working style.   

Being citizens of a Muslim majority country, Malaysian Muslims should know better that this worldly life is not the only life to be encountered. Indeed, Islam teaches us to work diligently in order to earn halal income and support the family. But not to the extent of neglecting family, friends and social responsibilities.

Surah Al-An’am verse 96 clearly indicates: “He causes the dawn to break; and He has made the night for rest, and the sun and the moon for reckoning; this is an arrangement of the Mighty, the Knowing.”

Benefits of good work life balance include: increase in productivity and motivation, reducing truancy, as well as gaining loyalty from staffs. The risks for physical and mental health can also be minimized [3].  Of course, long working hours are unavoidable especially for certain sectors such as healthcare, technical support and security. But for normal regular jobs, efficiency and common sense are the key. For instance, simple documentation works could definitely wait till morning. There's no need to discuss about work after working hours if it is not urgent. Working long hours should be the exception, not the rule. It’s about time that number of working hours should not dictate productivity; rather flexibility and ample time for family, friends and other self-improvement activities must be encouraged. This may sound easier said than done, but it is not impossible. Start with yourself, be an advocate for work life balance by being an exemplary employee and respect others' private time. Insya Allah the positivity can be spread and the others will follow suit.

The Untold Story in the Management of Diabetes Mellitus


Written by: Dr. Nur Syukriah Ab Rahman

Diabetes mellitus (DM) is one of the most important metabolic disease that hit the globe in the present millennium. It has been listed as one of the five leading cause of deaths and approximately six death per minute are associated to DM complications [1]. The report from National Health and Morbidity Surveys shown that there is an increasing trend in the recorded prevalence of DM for the past decades and surprisingly the overall prevalence of DM has been increased by more than doubled from 1996 to 2015 in Malaysia [2].

The earliest history recorded in the treatments of DM involved the use of plants. Metformin is one of the oral diabetic drug that is widely prescribed by the medical practitioner nowadays which is originated from the use of Galega officinalis (G. officinalis) Linn as herbal medicine in primitive Europe [3]. G. officinalis is a perennial herb with blue, white or purple flowers which is commonly found in most temperate regions and grows over three feet high.

Herbal medicine is one of the subcategories of complementary and alternative medicinal (CAM) therapies. Most of the people favor CAM over conventional therapies due to unsatisfied outcomes such as adverse side effects and higher treatment cost. SynacinnTM  is a polyherbal formulations that consist of five herbal medicine including Cinnamomun zeylanicum, Curcuma xanthorrhiza, Syzygium polyanthum, Orthosiphon stamineus and Andrographis paniculata and has been standardized against catechin, curcumin, gallic acid, rosmarinic acid and andrographolide respectively. It is believed that each herbal present in SynacinnTM could act through intelligent network that could produce synergistic effects to remediate DM conditions. In addition, the existing literatures and testimonials suggest promising venue for SynacinnTM to be scientifically validated and developed as an alternative drug in the management of DM.

The scientific research on the development of SynacinnTM as herbal medicine in the management of DM is still in progress and a group of researchers from UMT and UTM have put their blood and tears on this development. As for now, SynacinnTM is already available on the market for example Shoppe, Lazada or can be directly purchased from NatureMedic Laboratories Sdn Bhd. It is hoped that we one fine day we found the cure for this disease.

Mental Health Awareness


Written by Fathiah Zakaria
Mental illness has become one of the prevailing health problem nowadays. Mental illness happens to people from all walks of lives, professionals, students, parents and children. Among prevention and intervention methods available are counselling, therapeutic assessment (physiatrist), circle time and support group. DSM-5 is a Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association (APA). DSM-5 serves as the guidelines for psychiatric diagnosis and also treatment recommendations. Among types of mental disorder listed in DSM-5 are Anxiety Disorder, Autism Spectrum, Personality Disorder, Major Depressive Disorder, Social Communication Disorder and etc. [1]. In developed countries like United States, the treatment cost for mental disorder is covered by medical insurance.

There are numbers of Government entities, NGO and private practices that provide services related to mental health in Malaysia such as MENTARI Malaysia, Mental Illness Awareness & Support Association (MIASA), Relate Malaysia, Malaysian Mental Health Association and etc. In fact, most of the Government entities provides in-house counsellor and psychologist. If you feel you are having unstable emotional, changing in mental state condition, there is no harm of finding professional help. Counselling would be one of effective methods to deal with this condition. Counselling provides a safe space to talk about thoughts and feelings, subjected to counsellor’s ethics and confidentiality. It allows someone to talk with a professional who can help to work on specific issues that they are facing with. Try to find registered counsellor with notation (KB,PA) – “Kaunselor Berdaftar dan Perakuan Amalan” after their name, because they are registered with Lembaga Kaunselor Malaysia [2]. In the condition where further treatment and medical assessment is needed, counsellor will refer the clients to the psychiatrist.

World Health Organization (WHO) defined mental health as “a state of well-being in which every individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community” [3]. Let’s check on our mental state condition. Positive mental well-being results in blissful community and prosperous country. Remember that “loving ourselves works miracle in our lives”.
