Promotion from one geup to the next can proceed rapidly in some schools, since schools often allow geup promotions every two, three, or four months. Students of geup rank learn the most basic techniques first, and then move on to more advanced techniques as they approach first dan. Many of the older and more traditional schools often take longer to allow students to test for higher ranks than newer, more contemporary schools, as they may not have the required testing intervals.

Human Eye

( 눈 nun )

 




Difficulty Level:  Advanced Level      Surface: Offensive Target

The human eye ( 눈 nun ) is an organ that reacts to light and allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can differentiate between about 10 million colors and is possibly capable of detecting a single photon. The eye is part of the sensory nervous system.

The eye is not shaped like a perfect sphere, rather it is a fused two-piece unit, composed of the anterior segment and the posterior segment. The anterior segment is made up of the cornea, iris and lens. The cornea is transparent and more curved, and is linked to the larger posterior segment, composed of the vitreous, retina, choroid and the outer white shell called the sclera. The cornea is typically about 11.5 mm (0.3 in) in diameter, and 1/2 mm (500 μm) in thickness near its center. The posterior chamber constitutes the remaining five-sixths; its diameter is typically about 24 mm. The cornea and sclera are connected by an area termed the limbus. The iris is the pigmented circular structure concentrically surrounding the center of the eye, the pupil, which appears to be black. The size of the pupil, which controls the amount of light entering the eye, is adjusted by the iris' dilator and sphincter muscles.

Light energy enters the eye through the cornea, through the pupil and then through the lens. The lens shape is changed for near focus (accommodation) and is controlled by the ciliary muscle. Photons of light falling on the light-sensitive cells of the retina (photoreceptor cones and rods) are converted into electrical signals that are transmitted to the brain by the optic nerve and interpreted as sight and vision.

* Please see a certified Master Instructor ( 사범님 sabeomnim ) for training. Proper guidance and instructions are needed to ensure safe training.

Surface Area Injuries

Collisions with the ground, objects, and other taekwondo practitioners are common, and unexpected dynamic forces on limbs and joints can cause injury. Taekwondo injuries can also occur in techniques if done improperly or from overuse of a particular body part. Taking a break from training or reducing the volume and the intensity of the training will allow the body to recover. For more information on Injuries »

Question. What is the korean terminology for Front Stance?

Front Stance is a precursor of the fighting stance ( 겨루기준비 gyeorugi-junbi ) according to some authors. Body should be relaxed in this stance ( 서기 sogi ). From the attention stance ( 차렷 charyeot ) with feet together, one foot is placed straight ahead of the other.

Taegeuk 태극 (in World Taekwondo (WT)) refers to a set of poomse 품새 used to create a foundation for the teaching of taekwondo. A poomse or form is a detailed pattern of defense-and-attack motions and techniques used in traditional martial arts. Each taegeuk form symbolizes a specific state thought to be indicative of the belt the student currently holds, and is represented in World Taekwondo (WT) by trigrams similar to those found in the four corners of the South Korean flag.

Various surfaces of the hand and feet may be engaged as the striking or blocking surface depending on which area of the opponents body is being targeted. This leads to a large array of hand and feet positions. The human body's shape is determined by a strong skeleton made of bone and cartilage, surrounded by fat, muscle, connective tissue, organs, and other structures.
