SECURITY SYSTEMS

It has always been a basic instinct for human beings to protect themselves and their properties from any identifiable threat. Even indwellers from long ago manifested this basic instinct by hiding inside huge caves to protect themselves from outsiders and other predators. In the present days, people realized that they should be more protected not against from any hunting predators but from the danger brought about by intruders, damage, loss and criminal activity. This prompted the need for technological advancement that will cater the need of the society with regards to their security. Thus, security system was born.

Security system is designed to protect the public from certain identifiable threats such as burglars, bombs, fires, etc. Urban population has become more aware on the significance of having security systems in their homes. Burglar or intrusion alarm is the most widely used alarm system inside the household. It is an electronic alarm used to alert the user if there are any intruders within the vicinity. Burglar alarms are further divided into two main types – home burglar alarms and perimeter intrusion detection.

However, security system is not only limited to the physical realm like airport, food, hospital, physical, school, shopping center and infrastructure security; it also covers other aspects such as the IT realm, political and monetary. The IT realm includes application, computing, data, information and network security. The political realm deals more with homeland, human, international, national and public security while monetary specifically deals with financial security.

There are a lot of technological innovations available which serves to protect the public; it can be purchased online or in the market which ranges from low-end to high-end devices. These are available in the market as CCTV monitors, intrusion alarm system, fire alarm and sprinkle monitor, hold-up or panic alarm and simple burglar alarms. It significantly contributes in helping the society prevent the incidence of burglary and other criminal activities.

It should be noted that in security systems, the “weakest link in the chain” is the one to be given more value. The protector needs to put into consideration and foresee all the possible points of attack from the intruder while on the other hand, the intruder need only analyze and pinpoint one single weak spot to focus with. However, this should not be a problem since many companies release a variety of quality products to secure households and protect important possessions.

NATURAL REMEDIES FOR ADHD

It is not easy to have a child diagnosed with Attention Deficit/Hyperactivity Disorder. Children who are diagnosed with ADHD have a poor performance in school, lack social skills, have few friends, suffer physical health problems and have poor relationship with their parents and other family members.

ADHD is a chronic syndrome of age-inappropriate inattention, distractibility, impulsivity, and restless overactivity.¹ It is the most common diagnosed behavior in North America, occurring in 3% to 8% among school children.² ADHD affects not only the patient but also parents, siblings, friends, and school staff. The main issue now is to educate the people close to the patients- parents, family members and their significant others (in the case of adult patients) regarding its causes, prevention, treatment and palliation.

There are well-established medications and behavioral treatments for ADHD including the two-best documented stimulants methylphenidate and amphetamine.³ There are also other treatments proposed for treating patients with ADHD in a natural way. These were based from scientific documentation and clinical trials. One example is elimination diets (Feingold, oligoantigenic, few foods) which have proven in some selected subgroups that it is as good as some drugs and behavioral techniques.

Some alternative treatments were also highlighted during the November 1998 NIH Consensus Development Conference.⁴ These include enzyme-potentiated desensitization which targets food or additive sensitivity, elimination of sugar alone, amino acid supplementation which is a precursor of catecholamines and serotonin, essential fatty acid supplementation, L-carnitine which promotes EFA (essential fatty acid) metabolism, vitamins, iron supplementation which is a co-factor in making catecholamines, zinc supplementation which serves as a co-factor for many enzymes, Chinese herbals which is based from clinical experience,  homeopathic preparations, laser acupuncture which stimulates foci for calming, EEG biofeedback which acts by suppressing theta while increasing beta, relaxation training which lowers arousal and enhances muscle tone, meditation which promotes autonomic effect and enhances focused attention, hypnosis which lowers arousal, mirror feedback which improves deficient self-awareness, channel-specific perceptual training which enhances basic readiness skills and focus, vestibular stimulation which modulates behavior, attention, perception; and massage which provides muscular soothing.

It should however be noted that when using alternative treatments for ADHD, the family should consult an expert clinician. This does not mean that these alternative treatments are ineffective but these treatments should be proven scientifically first before being used as treatment for ADHD. The clinicians should discuss these treatments comprehensively with the family as well as the risks that may come along with the treatment and the scientific basis for efficacy of the treatment. This will help the family decide whether the possible benefit is worth the expense and risk and will aid the family in choosing the best treatment for their loved one.
