The purpose of this study was to examine the Roche technique performed by three male subjects in 2003 Taegu World Students Game. Conclusions are as followed. If the angular momentum was increased to counter-clockwise on voulting, the momentum acted like an interrupting factor of body spinning force. The biggest body angle was at VTD phase and the smallest was at BTO phase. At the phase of contacting on vaulting board and taking off from the vaulting board, the biggest personal angle difference between VTD and BTO was found. As the Roche technique was needed not only to fly high but also to increase body spinning rate, the projection angles of Roche technique were showed smaller than those of Cuervo technique. The angular velocity was peak during 2 times forward turn phase. The angular momentum was influenced by angular velocity from BTO and VTD phase.

The purpose of the study was to perform trend analysis of the exercise content i.e. element difficulty distribution scores, element group distribution scores obtained by the athletes during 2014 Korea Cup International Gymnastic finals. The conclusion drawn from the analysis are as follows: Firstly in terms of tournament technical difficulty value, Korean athletes showed characteristics of reliance on swing element rather than strength hold element which could actually secure higher difficulty scores. Secondly, skill acquisition of higher difficulty value is demanded by taking advantage of familiar characteristics from the swing element i.e. Jonasson and Roll bwd. Slowly with str. arms and body to swallow (2s.). Thirdly, development of sensory training and strengthening exercise program are essential to enhance strength hold technique.

In this study we investigate the ability of the yield spread to predict economic recessions in two Asian economies. For our purpose we use the data from two emerging economies (South Korea and Thailand) that are also known for their openness in terms of exports and imports. We employ both two-regime Markov-Switching model (MS) and three-regime MS model to estimate the probability of recessions during Asian crisis. We found that the yield spread is confirmed to be a reliable recession predictor for Thailand but not for South Korea. The three-regime MS model is better for capturing the Asian financial crisis than two-regime MS model. We also tried to find the duration of economic expansions and recessions. We tested the hypothesis of asymmetric movements of business cycles. The MS results are also compared with that of the standard probit model for comparison. The MS model does not significantly improve the forecasting ability of the yield spread in forecasting business cycles.

There is a large number of old athletes participating golf, and the shoulder, especially the nondominant or lead arm, appears to be at greatest risk for golf-related injury during extremes of motion. To reduce and prevent the risk of injury and improve the performance of golf, golfer should understand the biomechanics of the golf swing, increase flexibility, and perform stretching and strengthening exercises regularly .

The purpose of this study was to identify factors influencing intention to stay among new graduate nurses. The participants were 127 new graduate nurses working at A University hospital in Gyeonggi Province. Data were analyzed by descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple regression. The results showed that job satisfaction, reality shock, working period, and resilience were significant predictors of intention to stay and explained for 44.2% of the variance in intention to stay. The findings of this study suggest that interventions focusing on reducing the reality shock through pre-experiences or trainings in clinical situations and enhancing the resilience are needed to improve intention to stay for the new graduate nurses. Also it is necessary to establish a support system and work environment to improve nursing job satisfaction, and a long-term education program of more than 6 months is needed to help new nurses adapt to work.

The purpose of this study is to verify the possibility of applying sports psychological training based on a solution-based short-term counseling approach. the study subject was a total of 8 units as one of the national athletes of Vietthlon. the measurement tools consisted of questionnaires and in-depth consultations, and the pre- and post-changes were measured and compared based on the results of the winter sports competitions. The results of the study showed that the negative thinking of the athletes was reasonable and positive change. Within a short period of time, confidence and competence in performance were improved, and cognitive anxiety was greatly reduced.

The purpose of this study was to find the risk factors of injury by FMS and to investigate the effects of 12-weeks' combined training program on body imbalance, physical fitness, muscle strength and FMS score in woman rugby players of the national team. Fourteen subjects were woman rugby national players to participate in the 17th Incheon Asian Games. These players tested FMS and performed 12 weeks' (May~Aug, 2014) combined training program (4days, 120min${\geq}$). Statistical evaluation was undertaken using paired t-test (pre vs. post). The results of this study were as follows; Frist, the score of FMS test on Deep Squat, Hurdle Step, Active Straight Leg Raise, and Trunk Stability Push up were significantly increased after 12 weeks' combined training program (p<.05), and also Inline Lunge (p<.01) and Rotary Stability (p<.001) were significantly increased. However, Shoulder Mobility was not significantly increased(p=.104) although the tendency of increased was FMS score. Second, the sum of the entire item was significantly increased after combined training(p<.001). These results suggest that 12-weeks' combined training program has effect of improving FMS score and low-injury risk in woman rugby national players. Therefore, we consider that FMS have effect on prevention of athletic injury and improvement of athletic performance in woman rugby national players.
