This study aimed to investigate the factors that influence the attitude toward doping and to provide useful information for developing a doping prevention program suitable for Korean athletic players. One hundred and seventy-two players who enrolled in Korea Association of Athletics Federations were participated in this study and they filled in the questionnaire about demographic factors, information on doping, perfectionism, and perceived motivational climate. Collected data were analyzed by using stepwise multiple linear regression for exploring the main factor that affect the attitude toward doping depending on field and track events. All adult players have more permissive attitude toward doping than adolescents. In track event, while players who are sensitive to coach's criticism have more permissive attitude toward doping, players who focused on personal standards have more repressive attitude toward it. These results would be useful to develop anti-doping strategy for Korean field and track players.

The usual definition of and urban resort was a place vastly different from places of daily life such as a theme park or other tourist destination. At the same time, revival of the combination of usual and unusual spaces, in a way like the mixed "Hare"(Special occasion of public event) and "Ke"(Daily life) spaces of communities of old Japan, is part of the idea of urban resorts. And they are places, which start by making a comfortable urban environment for citizens, providing a daily life full of culture and promoting a city′s identity to visitors. if we think about the kinds of structural elements of urban resorts, the usual elements include community, local culture and industry, while the unusual elements include symbols, festivities and interaction. Kobe Wing Stadium is a venue for the 2002 FIFA World Cup hosted by Korea and Japan. The city will build the stadium, but after construction management will be given over to private enterprise, hoping to utilize that sector′s business know how. A competition was held to determine the private executor who would be entrusted with the planning, design, construction and management of the project, considering the conditions of the area, the stadium′s relationship to it and local revitalization. The competition was won by a private enterprise (Kobe Steel Obayashi Group). The them of "Creation of a Sports Community Park" grapples with the large issue of the facility′s relationship with the community. American geographer Yi-fu Tuan coined the word "topophilia" to indicate love of a place. No other word could better describe the desired urban resort nature of the stadium. From this historical perspective it seems that stadiums have great potential as urban resorts. The factor that will determine their success is the attitude of citizens toward them, in short whether they develop topophilia for them or not. We examined the urban resort nature of Kobe Wing Stadium. Regarding daily life, we saw the attempts to revive the local community, the possibility of deepening the local culture and the weakened state of local industry. As a place that is for more than daily life, we saw the certainty of the stadium′s symbolism, its potential as a place for festivities and the test it will face as a space for interaction. Even though several issues are left for future resolution, evaluating Kobe Wing Stadium through these elements of an urban resort, it is clearly founded in the daily life of the community while providing a venue for "Hare"occasions. Fulfilling the roles of an urban resort, it provides many opportunities for local residents to enjoy their and gives visitors a reason to come repeatedly.

This study is conducted to explore the possibility of service convergence to promote mobile learning. This study has attempted to identify how mobile learning service is provided, which services among them are considered most popular, and which services are highly demanded by users. This study has also investigated the potential opportunities for service convergence of mobile service and e-learning. This research is then extended to examine the possibility of active convergence of common services in mobile services and e-learning. Important variables have been identified from related web pages of portal sites using social network analysis (SNA) and association rules. Due to the differences in number and type of variables on different web pages, SNA was used to deal with the difficulties of identifying the degree of complex connection. Association analysis has been used to identify association rules among variables. The study has revealed that most frequent services among common services of mobile services and e-learning were Games and SNS followed by Payment, Advertising, Mail, Event, Animation, Cloud, e-Book, Augmented Reality and Jobs. This study has also found that Search, News, GPS in mobile services were turned out to be very highly demanded while Simulation, Culture, Public Education were highly demanded in e-learning. In addition, It has been found that variables involving with high service convergence based on common variables of mobile and e-learning services were Games and SNS, Games and Sports, SNS and Advertising, Games and Event, SNS and e-Book, Games and Community in mobile services while Games, Animation, Counseling, e-Book, being preceding services Simulation, Speaking, Public Education, Attendance Management were turned out be highly convergent in e-learning services. Finally, this study has attempted to predict possibility of active service convergence focusing on Games, SNS, e-Book which were highly demanded common services in mobile and e-learning services. It is expected that this study can be used to suggest a strategic direction to promote mobile learning by converging mobile services and e-learning.

The purpose of this study is to collect official world records for a total of five years from 2015 to 2019 from the modern pentathlon world competition database to reveal the impact of shooting types and characteristics on the record. To that end, the entire shooting spree was analyzed for all male and female athletes participating in the UIPM Level 1 World Cup and World Championships. According to the study, the number of round trips and the number of cars increased, the number of shooting accumulation deteriorated, the best record in the first round trip 3rd round, and the worst record in the fourth round trip 5th round. In addition, the deviation values are accumulated according to the fire recording or without success of the first step round trip by 9 percent in accordance with the growing number of the deviation is an increasing trend is, is that over time. Modern pentathlon at the success of the first step is more important and as fire can just hit first step in the event of great effect in reducing record. Based on these studies, the factors and characteristics that affect shooting accuracy are identified, and follow-up research linked to track records is necessary to match the characteristics of the combined competition.

The purpose of this study was to review the effects of the physical fatigue induced by overtraining on cognitive information processing and emotional change of athletes by neurophysiologic study. And to provide basic data for the athletes and coaches in the sports field to improve understanding of the overtraining symptoms from the brain physiological point of view. We reviewed the domestic and international academic materials and research reports published in the last 20 years using electronic databases and examined the literature that is consistent with the purpose of this study among the retrieved documents. Based on the reviewed literature, we examined the cognitive information processing and emotional change of the athlete according to the training, and overtraining can accumulate the fatigue of the body, which can cause severe side effects in terms of cognitive ability and emotional ability of athletes as well as deterioration of performance. The study using P300 and EEG cerebral hemispheric asymmetry difference indices also confirmed the possibility of a new approach to understand psychological and physiological effects of overtraining on information processing and emotional changes.

Purpose: We aimed to investigate trunk angle and muscle activation of the extremity and back to evaluate the effect of chest compression on work-related musculoskeletal disorders in 119 emergency medical technicians (EMTs). Methods: Eighteen 119 EMTs performed 2-minute chest compression without interruption on a cardiopulmonary resuscitation manikin, during which we measured changes in the trunk and shoulder joint angles, muscle activation (triceps brachii, biceps brachii, erector spinae, gluteus maximus, pectoralis major, rectus abdominis, and rectus femoris) and chest compression accuracy. Results: The decrease in trunk angle by trunk muscle activation was the highest in event 2, the major direction of chest compression. Both shoulder joint angles had no significant difference. Muscle activation of the triceps brachii (p < .01), biceps brachii (p < .05), rectus abdominis (p < .05) and rectus femoris (p < .01) significantly increased during the compression phase compared with the decompression phase, with the rectus femoris showing an increase of 19%. Muscle activation of the erector spinae significantly increased in the decompression phase compared with the compression phase (p < .01). Conclusion: 119 EMTs mainly use the triceps brachii, biceps brachii and pectoralis major muscles during chest compression.
