Background: In clinical practice, active knee extension (AKE) test has been widely used to measure hamstring flexibility. During the AKE test, the knee extension is repeated six times. The first five repetitions are considered as warm-up, and the sixth is used as baseline. In order to accurately measure the subject's inherent flexibility, warm-up trials have been proposed as mentioned above; but currently, the evidence is insufficient. Design: Cross-sectional study. Methods: Forty-three healthy adults participated in this study. The AKE was performed slowly after flexing the hip and knee joints by 90° in a supine position. The knee was extended as far as could be done without causing discomfort or pain. When reaching the end range, knee flexion was performed without stopping. As per standard protocol, the subjects performed the knee extension six times. Results: There was no significant difference between the AKE value in the first trial with those in the other five trials. During the repetitions, the average value in the group with higher flexibility tended to decrease and the Intraclass correlation coefficient gradually decreased. Conclusion: Successive repetitions of the AKE test can misrepresent an individual's inherent hamstring flexibility. In order to avoid a decrease in hamstring flexibility, it is strongly recommended that individuals with high initial hamstring flexibility avoid unnecessary repetitions of the AKE test.

According to the changes of the medical environment of the times, it is necessary to discuss the issues of the doctor s medical guidance and to conduct continuous research so that alternatives can be prepared systematically. Furthermore, in order to enhance the professionalism of radiological technologists and to develop the medical technician system, the new Radiological Technologist Independent Act has been established, which contains the overall contents of the scope of work, professional qualifications, and specialized education of radiological technologists, and provides quality medical services to patients through professional procedures and treatment. In order to increase the level of medical care, the purpose, definition, mission, role, and scope of work specified in the Medical Act, Medical Service Technologists, etc. Act, the Enforcement Decree, and the Enforcement Rules were variously analyzed and new directions were presented. First, the definition of a medical technician should use a generic term so that the factors of conflict and prejudice could be resolved. Second, change the doctor s guide to doctor s prescription; and then legislate the authority to sign and write medical records after examination by radiological technologists, thereby prohibiting unlicensed technicians that seriously endanger patient safety. Third, an accurate definition of radiological technologists roles should be established; not only selection and management of radiological technologists work but also procedures and treatment for each radiology field should be specified to suit the current medical system. Fourth, a professional radiological technologists qualification system and a specialized education system should be established in order to secure human resources that could provide patients trust in procedures and treatment based on professional knowledge and experience in the field of radiology. Fifth, the Education and Evaluation Institute should be operated in Korea education system to educate the professional knowledge and competency for students. In addition, it is necessary to in-depth analysis of foreign cases could be applied to the medical system and education system in Korea; it could strive to nurture systematic human resources.

Background: To prevent or reduce the risk of strain injury, various approaches, including stretching techniques are currently being used. The effect of proprioceptive neuromuscular facilitation (PNF) and static stretching on flexibility has been demonstrated; however, it is not clear which one is superior. Objects: This study aimed to evaluate the differences between the effects of PNF and static stretching performed at various intensities on muscle flexibility. Methods: The maximum voluntary isometric contraction (MVIC) of the hamstrings using the PNF stretching technique was performed in the P100 group, while 70% of the MVIC was performed in the P70 group. The MVIC value obtained during the PNF stretching in both groups was used as a reference for setting the intensity of static stretching. Static stretching was performed at 130% (S130), 100% (S100), and 70% of the MVIC (S70). The active knee extension (AKE) values, defined as the knee flexion angle were measured before stretching (baseline), immediately after stretching (post), and at 3 minutes, 6 minutes, and 15 minutes. Results: PNF stretching produce a greater improvement in flexibility compared with static stretching. Specifically, the ΔAKE was significantly higher in the S100 and S70 groups than in the P100 group at Post. In the comparison of ΔAKE over time in each group, the ΔAKE at Post showed a significant decrease compared to the value at Baseline in the S130 group; however, no significant difference was observed at 6 minutes while a significant increase was noted at 15 minutes. Conclusion: This study found that PNF stretching is more effective than static stretching with respect to increasing and maintaining the flexibility of muscles. In addition, the increase in flexibility at maximal intensity was similar to that observed at submaximal intensity during both PNF and static stretching.

Golf, one of the sports becoming popularized has different advantages and disadvantages to psychological health. In regards to physiological features of golf, exercise intensity is relatively low in young groups under 40-year-old but those in old groups ranging from late 40s to 50s, they had low to mid and high exercise intensities. Such exercises are more suitable for them because they require high colory consumption. For beneficial physiological factors of regular participation golf include decreased cardiovascular disease, improved high blood pressure, musculoskeletal system, and lung function for elderly, prevention of cancer, and reduced hospitalization of children suffering from asthma. Although physiological benefits of golf include increased life quality and happiness as well as reduced depression and anxiety but too much golf may result in addiction, resulting in disruption of work ability and of routine job in home and office. However, it does not mean that golf has only negative perspectives but rather dual factors of increasing life quality along with happiness and enjoyment. One of the major social issues related to golf is gambling and thus, we need a strong solution for eradication. It is too early to determine that golf addiction is related to golf gambling as research on this is not enough. Still, it is reported that frequency of sudden die from golf exercise is higher compare to other sports but a wider range of researches are required. For those mid to elderly people having cardiovascular or any other risk factors, they need to have a regular check with doctor. Too much golfing may cause frequent chronical musculoskeletal damage such as upper limb damage (inner epicondylitis and rotator cuff tear), rib, back, and lower body. In such cases, number of participation has to be limited and at the same time, damage shall be prevented by executing flexibility and muscle strengthening exercises that go well with golf.
