In the present study, capability of nanobiotics in repairing tendon injuries commonly occur in Taekwondo sport is investigated and some approaches are proposed. In this regard, a brief review on the types and application of nanobiotics is presented. Their capabilities and limitation are discussed. Next, different type of tendon injuries in Taekwondo athletes are discussed along with their treatment approaches. Based on the presented data, a nano-scale feasible robot model carrying nanobiotics is proposed for repairing tendons. Finite element simulations is also conducted to show the effectiveness of the repairing process using nanorobots equipped with nanobiotics. This repairing procedure is a combination of mechanical and chemical treatments. The results indicated that using nanobiotics on nanorobots arms in the repair of tendon injuries has many benefits. First, drug delivery is directly injected to the target section. Second, Due to the nanorobots small sizes more acute treatment is possible. Finally, since the control of the nanorobots are assisted with computers, the possibility of human error reduces significantly. The proposed method of the present study could be utilized by other scientists and technological industry in developing final nanorobots with nanobiotics carrying capacity.

Sport has no age limit and can be done anywhere and in any condition with minimal equipment. The existence of sports spaces in all parts of the world is considered a citizen's right. One of the activities carried out in this field is installing sports equipment and structures in parks and encouraging citizens to use this equipment for physical health with the least cost and facilities. Installing sports structures in open spaces such as parks is a practical step for developing citizens' sports. Although using devices in parks is acceptable, it is more critical to meet scientific and technical standards. The components of these structures must have high strength and endurance against changes in environmental conditions such as humidity, temperature difference, and corrosion. Among the various causes of material degradation, corrosion has always been one of several fundamental causes of metal equipment failure. Sports structures in open spaces are not safe from corrosion. Uniform corrosion is the most common type of corrosion. This corrosion usually occurs uniformly through a chemical or electrochemical reaction across the surface exposed to the corrosive environment. Rust and corrosion of outdoor sports structures are examples of this corrosion. For this reason, in this research, with the green synthesis of silica nanoparticles and its application in outdoor sports structures, the life span of these structures can be increased for the use of physical exercises as well as their quality.

Background The purpose of this study was to identify comprehensive hand injury patterns in different pediatric age groups and to assess their risk factors. Methods This retrospective study was conducted among patients younger than 16-year-old who presented to the emergency room of a general hospital located in Gyeonggi-do, Republic of Korea, and were treated for an injury of the finger or hand from January 2010 to December 2014. The authors analyzed the medical records of 344 patients. Age was categorized according to five groups. Results A total of 391 injury sites of 344 patients were evaluated for this study. Overall and in each group, male patients were in the majority. With regard to dominant or non-dominant hand involvement, there were no significant differences. Door-related injuries were the most common cause in the age groups of 0 to 3, 4 to 6, and 7 to 9 years. Sport/recreational activities or physical conflict injuries were the most common cause in those aged 10 to 12 and 13 to 15. Amputation and crushing injury was the most common type in those aged 0 to 3 and 4 to 6 years. However, in those aged 10 to 12 and 13 to 15, deep laceration and closed fracture was the most common type. With increasing age, closed injuries tended to increase more sharply than open injuries, extensor tendon rupture more than flexor injuries, and the level of injury moved proximally. Conclusions This study provides a comprehensive overview of the epidemiology of hand injuries in the pediatric population.

Baseball is a life sport that gives vitality to people. However, currently available leg guards do not have a variety of sizes and it is very difficult to purchase a leg guard that is suitable for the size of a specific consumer. Therefore, this study investigated the size system of a leg guard sold in the market and suggested a grading deviation suitable for the legs of Korean males. The results of the study were as follows. First, most brands were sold only in three size systems as children's, teenagers, and adults. Adult size systems were not subdivided. Second, Korean male legs were classified into Group 1 (large girth and height and lower body muscle) and Group 2 (small girth and height and low underbody muscle). Third, the size system is based on vertical items such as height and mid-thigh circumference. Each group produced 10 sizes. The smallest height or the largest height was also found to be about 4.5 to 5.0cm smaller or larger than the sample size for each group. The total length of the leg guard was about 2.5cm when the height was increased or decreased by one size. It was confirmed that the deviation of the circumference of the mid-thigh should be about 2.0cm larger or smaller than the sample size even if the height is the same. The deviation of the knee circumference and ankle circumference was smaller than the other circumference. In conclusion, the dimension combinations of the leg guard must be set differently to provide a leg guard with high size suitability according to leg type.

The purpose of this thesis is to make an effective Korean Hip Hop culture and suggest a new style direction in classifying the types of fashion styles of the Hip Hop musicians and studying their features. They are surveyed in stage costumes, hair styles, make-ups, accessaries, and total fashion styles, and then classified into Normal Hip Hop Style, Casual Hip Hop Style, Sporty Hip Hop Style, Mix & Match Hip Hop Style, and Classical Hip Hop Style. The results of the study are as follows: First, Normal Hip Hop Style is the most general and universal Hip Hop fashion type. They wear clothes in bigger sizes and exaggeratively. And also a cornrow hair style, a tattoo, and a piercing represent marked individualities. Second, Casual Hip Hop Style is more active and practical than Normal Hip Hop Style. Their blue jeans and T-shirts express more simple and polished style. And also they make variable fashion styles and hair styles such as a cornrow hair and a buzz cut. Third, Sporty Hip Hop Style is from B-boy's clothes when they do active and violent break dancing. As NBA basketball games are popular, they wear training clothes, breeches, big T-shirts, and jumpers & caps on embroidered sport team's names. Their hair style is short or natural and also they have caps or hoods to present active mood. Fourth, Mix & Match Hip Hop Style is existed variable elements in one style. The typical type of this style is jacket & blue jean. It is characterized by dress shirts, neck ties, blue jeans, sneakers, beards, and moustaches. Fifth, Classical Hip Hop Style is from African Americans. They try to express assimilated appearance of Anglo-Saxons. They wear black suits, shoes, hats, and sunglasses to represent formality and elegance. In the above results, there are variable fashion styles in one Hip Hop music genre and also fashion style is changed with musical inclination. This thesis is an important guide to produce variable and creative Hip Hop fashion styles in Korean Hip Hop culture.

Musculoskeletal neck dysfunction syndromes are common in outpatient musculoskeletal pain practice. The underlying musculoskeletal and neurologic causes of pain are variable. In the management of these patients, it is important to accurately identify and treat these pain generators to optimize patient outcome. It is the purpose of this review to discuss three main categories of functional anatomy, the role of superficial/deep muscular system and the scientific evidence for optimal physical therapy intervention for cervical dysfunction. Specifically there is evidence of lowered microcirculation in the upper trapezius muscle, morphological signs of disturbed mitochondrial function which appears to be limited to type I fibers and an increased cross-sectional area of type I muscle fibers despite a lower capillary to fiber area ratio. In acute neck pain syndrome, changes in muscle activity of painful muscles may result from segmental and supraspinal inhibitory effects. Muscle activation is closely related to the control of joint movements and postures and it is difficult to separate the influence of the two components. Both the altered muscle recruitment patterns and altered kinematics appear to be a poor adaptation for pain of the head - neck region, as they are likely to result in increased compressive loading in the cervical spine, affecting muscles, articular structures such as zygapophyseal joints, connective tissues and neural tissues which are all peripheral generators of referred pain. The rectus capitus posterior minor muscle shows that it is one of the most important muscles of the suboccipital region. In this article, i reviewed the anatomy, neurophysiology, function and dysfunction as well as the treatment of cervical dysfunction.

Accident reports from 1991 to 2000 of a steel company were used to analyze which factors induce industrial accidents. The subjects were 8,311 blue-collar workers, who sustained 114 occupational injuries and work on a continuous full-day 3-team 3-shift system of backward rotation(mornings to afternoons to nights). With respect to marital status, the occupational injury rate(OIR) on the married workers was significantly higher compared to unmarried workers. With respect to no, the OIR of those in their early 20s was significantly higher when compared to other age groups. The OIR of highly educated workers showed a reduction when compared with lower educated workers. The OIR of shift workers were significantly higher compared with the daytime workers. The OIR of type of work decreased across the steel manufacturing process, rolling process, machine maintenance section forwarding products section to the field management section. With respect to the block of shift work(morning, afternoon, and night shifts) by the type of work, the OIR of the night shift was higher than those of the morning shift in the steel manufacturing process or forwarding products section. The OIR of the machine maintenance section was slightly higher in the morning shift than those of the night shift. The OIR of the time of day of the shift workers reached a peak between 09:00 and 11:00. The OIR of a slight injury to shift workers decreased across the night, afternoon, to morning shifts whereas the OIR of a serious injury tended to decrease across the night, morning, to afternoon shift. The body parts most commonly injured were the arm and the crus.
