Clay-shoveler's fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler's fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2~T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler's fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler's fracture is one possibility to consider.

빠른 변화를 가지는 운동 동작을 분석하는 것은 쉬운 일이 아니다. 그러나 이를 동영상으로 취득하여 동영상 파일을 분석하는 것은 쉬운 일이다. 더욱이 PC의 보급과 디지털 캠코더의 보급으로 동영상 파일의 취득이 용이해 짐에 따라 일반인도 손쉽게 동영상 분석을 할 수 있는 환경을 가지게 죄었다. 본 연구에서는 골프 동작을 동영상 파일에 담아 분석할 수 있는 시스템을 설계하고 이를 구현하여 보았다. 또한 영상 흐름을 반영할 수 있는 편집 방식을 개발하고 이동 추적 알고리즘을 사용하여 골프 스윙 분석을 보다 용이하게 개선하였다.

Objective : The purpose of this study was to describe the correlation between the activity of the muscles of upper and lower limbs of a golf driver swing according to shoulder injury. Method : The subjects were 18 professional golfers (7 male in KPGA and 11 female in KLPGA). Using surface electromyography, we evaluated muscle activities during the golf drive swing. Surface electrodes were used to record the level of muscle activity in the left Deltoid(MD), Triceps Brachii(TB), Pectoralis(PM), Trapezius(UT), Rectus Femoris(RF), Vastus Medialis Obilique(VMO), Biceps Femoris(BF), Gastrocnemius(GCM) muscles during the golfer's swing. The golf swing was divided into five phases: take away, forward swing, acceleration, early follow through, late follow through. Results : The results can be summarized as follows: MD, VMO had statistically significant difference in take away phases, GCM had statistically significant difference in acceleration phases, MD, PM, VMO had statistically significant difference in early follow through phases, PM had statistically significant difference in late follow through phases, Conclusion : Muscle activity of the 8 muscles(Deltoid, Triceps Brachii, Pectoralis, Trapezius, Rectus Femoris, Vastus Medialis Obilique, Biceps Femoris, Gastrocnemius) along the shoulder damage or absence of has shown that they are organically connected to each of the phases.

The purpose of this study is to compare and analyze the muscle activations between the professional golfers without low back pain symptom and the professional golfers with low back pain symptom, and so identify the stress related to golf swings, and provide the basic data to minimize the low back pain and the injury risk. Using surface electrode electromyography, we evaluated muscle activity in 6 male professional golfers during the golf drive swing. Surface electrodes were used to record the level of muscle activity in the Abdominal Oblique, Elector Spinae, Rectus Abdominis, Gluteus Maximus muscles during the golfer's swing. These signals were compared with %RVC(Reference voluntary contraction) which was normalized by IEMG(Integrated EMG). The golf swing was divided into five phases: take away, forward swing, acceleration, early follow through, late follow through. we observed patterns of trunk muscle activity throughout five phases of the golf swing. The results can be summarized as follows: RES(Right Elector Spinae) had statistically significant difference in take away phase, LGM(Left Gluteus Maximus), LRA(Left Rectus Abdominis), LOA(Left Oblique Abdominal) had statistically significant difference in forward swing phase, RES(Right Elector Spinae), RGM(Right Gluteus Maximus), ROA(Right Oblique Abdominal) had statistically significant difference in acceleration phase, RES(Right Elector Spinae), RGM(Right Gluteus Maximus) had statistically significant difference in early follow-through phase, LES(Left Elector Spinae), RGM(Right Gluteus Maximus) had statistically significant difference in late follow through phase.

This study aims to quantitatively compare and analyze kinetic variables in the motion of male and female professional golfers to suggest basic scientific materials for golf iron swing. Five male and five female professional golfers participated in this experiment. Ground reaction force and foot pressure were measured during performing 10 swings for each participants using an iron club. The result of the ground reaction force indicates that the force occurs at the left foot toward right(-) direction in the mid-downswing(E3) and impact(E4) events in X-axis, while it occurs at the right foot toward anterior(-) direction in Y-axis for both male and female, showing a big difference between them. Also, in Z-axis, large force occurs at the left foot in most events. The analyzed result on foot pressure indicates that men have the highest pressure and area at the left foot, and women have the highest ones at the right foot in the mid-downswing(E3) and impact(E4) events in the max foot pressure, ground contact area and average pressure. It is considered that there is difference of central movement methods between men and women. Thus, different education and training on golf swing should be necessary by gender due to their different patterns of golf iron swing.

The purpose of this study is to investigate the structural relationship among brand dependence, brand attitude, brand satisfaction and repurchase intention of online golf goods consumers. To achieve the purpose of this study, a survey was conducted on consumers who had experience in purchasing golf goods online by visiting golf driving ranges in Seoul and Kyeonggi area. A total of 200 people were surveyed and 197 data were used for the final data processing. SPSS 23 and AMOS 23 were used for data processing. We obtained the following results. First, brand dependence had a positive effect on brand attitude, but it did not have a significant effect on repurchase intention.Second, brand attitude had a positive effect on brand satisfaction and repurchase intention; third, brand satisfaction had a positive effect on repurchase intentionFirst, face has been shown to have a significant impact on symbolic consumption propensity. Second, symbolic consumption tendencies have a significant impact on product satisfaction and intention to purchase new products. Third, product satisfaction has been shown to have a negative impact on the intention of purchasing new products.

The purpose of this study is to analyze the trend of the prize money and the performance factors, based on the data of 1,000 pro golf players provided by KLPGA(Korea Ladies Professional Golf Association) for the past 10 years from 2008 to 2017. First, in terms of the prize money, it increased a lot if we compare the data from 2008 and from 2017. However, it is still disproportionally favorable to the top players and is extremely disadvantageous to the middle-low players. Therefore, it is necessary to considerately care middle-low players. Second, in terms of performance factors, the players' skill has been improved steadily based on all of the factors considered: the scoring average, average putting, the birdie average, par save, par break, and recovery for the past 10 years from 2008 to 2017. Despite the fact that both players' performance and income have increased, it is prominent that the inequality between the players in terms of prize money becomes severe, which should be mitigated by external systematic support to maintain the current level of world-class players of Korea.

The impact sound of the golf club is one of the major factors to purchase it. Sound qualify evaluation techniques are mostly developed for harmonic sounds. Sound quality metrics for the impact sound is proposed in this study. Jury test, one of the typical subjective evaluation scheme, is carried out for evaluating the sound quality of 11 different golf drivers. Above subjective classification results are assumed to be the right answers. Conventional objective evaluation methods such as Zwicker loudness sensory pleasantness are calculated. Wavelet analysis and instantaneous loudness are applied in order to evaluate the transient sounds, which shows better correlation with the results from those by jury test.

덕유산 국립 공원의 양서류강을 1993년 4월 10일, 1993년 8월 8일부터 9일 두차례에 걸쳐 무주 리조트 골프장건설 지역과 지봉 지역에서 조사하였다. 골프장 건설 지역에서는 도롱뇽, 무당개구리, 두꺼비, 참개구리 및 북방산개구리가 관찰되었고 지봉에서는 꼬리치 레도롱뇽과 북방산개구리가 관찰되어 덕유산 국립 공원 지역에서 발견된 양서류는 환경처가 지정한 특정야생동물 꼬리치레도롱뇽, 도롱뇽, 및 두꺼비 3종을 포함하여 총 2목 4과 5속 6종이었다. 비교적 많은 9개체의 꼬리치레도롱뇽이 관찰된 지봉은 해발고도가 높고 수온이 낮으며 자연환경의 보존상태가 양호하고 인적이 드물어 꼬리치레도롱뇽 서식에 적합한 지역으로 사료되어 그 보호가 요망된다. 다수의 도롱뇽 유생과 2개체의 두꺼비를 포함하여 5종의 양서류가 관찰된 골프장 건설 지역은 공사가 진행됨에 따른 종과 개체수의 격감현상을 볼 수 있었다. 국립공원과 같은 자연환경 지역에서의 대형공사는 생물종 다양성 보존에 크게 역행하는 것으로 자제되어야 할 것이다.
