This study was to examine the effects of preshot-routine focused psychological skills training on psychological skills, self-management, and performance of Korean national golfer. The research participant was a 20 years-old male national player with 10 years and 3 months of golf experience who won various national tournaments. The duration of psychological skills training was 20 weeks and the levels of psychological skills, self-management, and performance were measured before and after application of psychological skills training. The results were as follows: Firstly, the levels of psychological skills factors, which were arousal regulation, concentration, and confidence, were improved. Secondly, the levels of self-management factors, which were mental management, behavior management, training management, and body management, were enhanced through psychological skills training. In conclusion, the psychological skill training had positive effects on psychological factors related with performance of a Korean national golfer.

Poly(3,4-ethylenedioxythiophene):poly (styrenesulphonate) (PEDOT:PSS) have been paid great attention for various application fields. Schottky diodes were fabricated using four different concentrations of TiO₂ in PEDOT:PSSsolutions. The forward current increased as the TiO₂ concentration increased, and the enhancement of forward current was nearly four orders of magnitude with respect to pristine PEDOT:PSS Schottky diode. To fabricate GaN Schottky diode, Ga₂O₃ nanorods were fabricated. The conversion of gallium oxide to gallium nitride is important due to the variety of application fields of GaN including ultra-violet and blue light emitting diodes. Two different synthetic routes have been employed to fabricate the gallium oxide. Energy dispersive spectroscopy (EDS) was performed to analyze the composition. The X-ray diffraction (XRD) pattern of gallium oxide and GaN can be assigned to orthorhombic GaO(OH) and hexagonal wurtzite structure GaN, respectively.

This study intended to find out the influence of a routine on an immature junior golfer for psychological skills, competitive anxiety, and golf performance variation. The subject was fifteen years old female who was in 8th grade, 4 years and 6 months career, one time won the title of a national tournament, but failed in rest of games. The training duration was total of 32 weeks which is consisted of 4 weeks educational period, 4 weeks routine training period of first session, 8 weeks of training camp, and 16 weeks routine training period of second session, while the study procedures and routine training details were described. However the authors could not accompanied with the subject for the training camp, so the duration was eliminated and the procedures/processes were not described. Consequently, game statistics were improved in actual tournaments through the 24 weeks of the training duration, the factors, soliloquy, imagery, goal setting, releasing tension, and emotional regulation, were improved in psychological skills, and also cognitive and physical state anxiety factors were decreased in competitive anxiety. For the results, the routine training has positive effect on junior golfer who is immature skillfully and physically.

도심지에서는 지형지물 및 건물 등에 의한 영향으로 가시위성 확보가 어려워지게 되며, 이는 사용자 위치결정 및 정확도에 영향을 미친다. 본 논문에서는 3D GIS 수치지도를 이용하여 서울 도심의 특정 지역을 3D 모델로 생성하는 기법에 대해 기술하고, 직선-폴리곤 충돌검사 알고리즘을 적용한 도심지에서의 가시위성 분석 기법 개발 및 필드 실험을 통한 검증을 수행하였다. 도심의 3D 모델을 이용하여 GPS/갈릴레오 단독 수신과 동시 수신의 경우에 대한 가시성을 DOP (Dilution of Precision)관점에서 분석하였다. Visibility of the satellite navigation is related to a environmental condition of a receiver. Obstacles like buildings and trees in urban areas can block signals and have effects on accuracy and reliability of positioning. This paper presents a method of creating 3D analysis model of urban canyon of Seoul using three-Dimensional digital map. Analysis techniques of visible satellites with Ray-Polygon Collision Detection and validation of algorithm through field tests are discussed. We have compared and analyzed the visibility of GPS and Galileo with respect to separate and simultaneous tracking in view of DOP (Dilution of Precision) using the 3D GIS digital map.

This study purposed to analyze and examine influence of imagery and relaxation training on an amateur golfer"s better performance, and how these affect anxiety and self-management. The subject was taught about the overall planning of imagery and relaxation training to understand the terms of the training, and trained imagery and relaxation training every single day. During 140 days of the total training, it consists of 10days of education period, 40 days of training period, and 90 days of a golf toumament preparation period. The subject, who was an amateur golfer aimed to acquire a pro-teaching license, did 40 days the training camp, and did video recording to use for skill-imagery and relaxation training. Relaxation breathing control and progressive relaxation were trained just after get up in the morning and just before go to bed in the night for relaxation training, and the prograssive training was put to practical used just before a swing for a round of golf. the training results were affirmative with paychological skill and athlete self-management, and reduced with cognitive state-anxiety and physical state-anxiety from CSAI-2. The number of stroke was also decreased with previous one before the training, and the subject achieved to get the pro-teaching license. Therefore, the results showed that imagery and relaxation training could reduce anxiety and encourage performance of golf with psychological stability.

The purpose of this study was for identifying the differences between goal orientation, self-management, performance strategy depended on male professional basketball players and verifying the effect of goal orientation, self-management on performance strategy. The subjects were collected in the 113 male professional basketball players who are registered in KBL to measure goal orientation. self-management and performance strategy. The data was analyzed with one-way ANOVA, Scheffe test, and stepwise multiple regression analysis via PASW 18.0 program. The results showed firstly that higher aged players has higher level of self-management, and higher careered players generally scored high point of self-management and performance strategy. Also the players who has longer playing time showed higher tendency of task orientation of goal orientation while the players who has shorter playing time showed higher ego orientation, and the longer playing time players showed overall higher performance strategy. Secondly, task orientation of goal orientation had effect on performance strategy. And self-management partially affected performance strategy, but it was not consistently.

본 연구는 일반 아마추어 골퍼들을 대상으로 핸디캡 수준에 따라서 심리상태(목표설정, 루틴, 집중력, 자신감)에 어떠한 점수 차이가 있는가를 분석하였다. 피험자는 총 199명을 대상으로 하였으며 심리상태를 알아 보기위한 도구로는 골프심리 질문지(GPQ: Golf Psychology Questionnaire)를 사용하였다. 본 연구결과에서 나타난 아마추어 골퍼들의 심리상태중 목표설정 부분에서는 핸디캡이 낮은(경기력이 높은) 아마추어 골퍼들이 핸디캡이 높은(경기력이 낮은) 아마추어 골퍼들보다 목표설정 점수에서 높게 나타났으며(p<.001) 루틴 및 자심감에서도 핸디캡이 낮은(경기력이 높은) 아마추어골퍼들이 핸디캡이 높은(경기력이 낮은) 골퍼들보다 점수가 높게 나타났다(p<.001). 그러나 집중력에서는 핸디캡이 낮은 골퍼와 핸디캡이 높은 골퍼들 사이에서는 점수의 유의한 차이가 나타나지 않았다. The purpose of this study was to find out whether psychological skills(concentration, goal-setting, routine, confidence, etc) effect golf performance of college amateur golfers according to different handicap. there were a total of 199 respondents to the questionnaire The golf psychology questionnaire(GPQ)was developed by Lydia(1999) and based on questionnaire from the MTE-1(Partington&Orlick.1998). It was translated into by Lee, Kyu-Hwan. It was 20-item questionnaire and responses were indicated on a 5-point Likert scale. Principal Component Analysis supported the content validity and Cronbach`s alpha revealed the internal consistency of the GPQ. handicap and mental analyses using the one-way ANOVA. expected, low handicappers rated higher on mental skill factors. more advanced players were more confident with club selection, mentally rehearse each shot more, as well as use more pre-shot routine, than higher handicap players. many beginners, intermediate or even advanced level golfers have lessons to improve their techniques. teaching professional golfers can helf with the physical aspects of the game, but are less able to instruct a golfer adequatery on psychological matters. The utilization of psychological skills has been shown to increase the amateur golf`s performance level.
