  • 몬테카를로 트리탐색은 최대우선탐색 알고리즘이며, 많은 게임 특히 바둑 게임에 성공적으로 적용되어 왔다. 삼목 게임에서 MCTS 간의 대국을 통해 성능을 평가하고자 했다. 첫 번째 대국자는 항상 두 번째 대국자에 비해 압도적인 우위를 보였으며, 최선의 게임 결과가 무승부가 됨에도 불구하고 첫 번째 대국자가 두 번째 대국자에 비해 우월한 이유를 찾고자 했다. MCTS는 반복적인 무작위 샘플링을 기반으로 하는 통계적 알고리즘이기 때문에, 특히 두 번째 대국자를 위해 전략을 요하는 시급한 문제를 적절히 대처하지 못한다. 이를 위해 전략적 MCTS(S-MCTS)를 제안하며, S-MCTS는 결코 삼목 게임에서 지지 않는다는 것을 보였다.

  • 게임 테크놀로지의 발전은 플레이어로 하여금 시각적 만족을 향유할 기회를 제공한다. 반면 게임 미디어가 재현해내는 서사적 향유와 만족감은 퇴보시키는 결과를 야기한다. 이야기 예술의 진화라는 관점에서 독창적 게임 스토리텔링의 소멸과 부재는 게임을 향한 플레이어들의 비판적 견해로 이어진다. 특히 게임 스토리텔링을 플레이어 층위에서 실제 작동하게 하는 퀘스트는 반복적이고 전형적인 내용으로 명령형의 과제만을 플레이어에게 제공하는 한계점에 와 있다. 이른바 퀘스트를 통한 의미 있는 플레이와 스토리텔링의 효과가 간과되고 있는 것이다. 이에 본 연구에서는 퀘스트의 대표적인 기능이라고 할 수 있는 수행성과 행동규정성을 넘어, 플레이어가 디자인된 퀘스트 규칙을 수정, 개편하는 편집가능성을 개념화하고, 그 특성을 운용하는 플레이어의 특성을 4가지로 유형화해보았다. 이를 통해 퀘스트의 편집가능성이 플레이어 스스로 게임성을 강화하고 게임 플레이에 몰입할 수 있는 기회를 제공함을 확인할 수 있었다.

  • An Optical disk driver is used in many electronic products besides the computers. In particular, the demands are recently increased as an optical disk player/recorder in the mobile products such as camcorder, portable player or in the home theater appliances, etc. However, the more the mobility is emphasized, the more the optical disk player is exposed to the disturbance inputs. For reducing the possibility of malfunction of the optical disk, we propose a nonlinear controller using the disturbance detecting algorithm based on the Kalman filter. Actual experiments were executed to verify the performance of the proposed method. The proposed method controls the tracking error signal within ${\pm}0.1{\mu}m$.

  • The purpose of this dissertation was to analyze the effect of trunk extension strengthening exercise on muscle performance of the upper limb in adolescent baseball player. The twenty people were studied : experimental group(10), comparative group(10). The experimental group has done trunk extension strengthening exercise for 8 weeks. The study analyzes isometric maximal strength of shoulder internal rotation. shoulder external rotation, elbow flexion, elbow extension, forearm pronation, forearm supination and ball speed. All of subjects were tested for 3 times ; pre, mid, post. The results were as follows; 1. Maximal isometric strength of upper limb, during trunk extension strengthening exercise in experimental group, shoulder internal rotation and external rotation showed it has slightly increased and comparative group showed it has no change, but not significant elbow flexion and extension significantly(p<0.05) increased after exercise either for 4 or 8 weeks compared with that of control group. Forearm pronation showed not significantly changed in both group, but significantly different between group either for 4 or 8 weeks. Forearm supination, significantly((p<0.05) increased after 8 weeks in experimental group. 2. Ball speed showed slightly increased but not significantly in experimental group. These results it may expect improvement of upper limb muscle performance of upper limb in adolescent baseball player. However, in case of shoulder a point of view of bunk extension strengthening exercise of this study hasn't a significant influence. More experimental studies are needs, hereafter which will use more experimental subjects and various methods of exercise and new application of treatment term to define significant change.

  • The purpose of this study was to evaluate performance characteristics in the success of team attack during volleyball game. Three dimensional analysis was performed with games of business teams. Analyzed variables were followed by the movement distance of a setter when A-quick was occurred, the position during the spike, the possibility area during the attack, the right and left distance of the assistance attacker, the distance between attacker and blocker, and the distance between blockers each others. 1. It is recommended that the movement distance of the setter be decreased in order to make stable set condition. 2. In order to make one person blocking, the formation was to be consisted of the right and left formation which was associated with the progressive attack performance of the assistance attacker. 3. It is useful to widen attack area. Also it is necessary to improve the enhancement of passing the ball against the blocking of an opponent player. Finally, it is necessary to develop kinematic variables to evaluate performance characteristics of players. Further study may consider the best defense position against the attack of the opponent player.

  • 조직은 환경변화에 적응하고 보다 나은 성과를 거두기 위해 지속적인 조직변화를 추구해야 한다. 하지만, 당연한 명제에도 불구하고 조직성과나 변화를 조작화의 어려움 때문에 해당 연구 분야에 대한 실증분석이 거의 이루어지지 않은 실정이다. 본 연구에서는 이러한 한계점을 극복하기 위해 조직변화나 성과를 객관적으로 측정하고 평가하기에 적합만 자료가 비교적 체계적으로 구축된 프로스포츠팀을 기업조직으로 상정하여 조직변화의 원인과 효과를 분석하였다. 이를 위해 미국프로농구(National Basketball Association: NBA)팀의 8개 시즌(2014~2015-2021~2022)의 경기기록 및 트레이드 자료를 체계적으로 수집하고 전처리하여 SPSS 26.0에 설치한 프로세스 매크로 4.2의 7번 모형을 활용하여 분석했다. 실증분석 결과, NBA의 경우 직전 시즌 성적이 낮은 팀일수록 트레이드를 통한 조직변화를 더욱 활발하게 시도하여 성과를 도출하기 위한 조직의 역동이 크다고 볼 수 있으며, 트레이드는 직전 시즌의 승률과 해당 시즌 승률 간의 정(+)적 관계를 매개하는 것으로 나타났다. 하지만, 트레이드를 통한 팀의 직전 시즌 성적의 간접효과는 각 구단의 상황에 따라 다르게 나타나는 것으로 드러났다. 직전 시즌 플레이오프에 진출한 팀은 그렇지 않은 팀에 비해 같은 성적일지라도 트레이드를 적게 시행하는 경향성을 보이며, 직전 시즌의 성적이 해당 시즌의 성적과 높은 관련성을 지닌다. 반면에 직전 시즌 플레이오프에 진출하지 못한 팀은 상대적으로 큰 규모의 트레이드를 단행하는 경향성을 보였으며, 이 경우 트레이드의 매개효과는 사라지는 것으로 나타났다. 즉, 직전 시즌에 플레이오프 진출에 실패한 팀은 같은 승률을 달성하였더라도 플레이오프에 진출한 팀에 비해 트레이드를 통한 성적변화가 더 크게 발생한다는 것을 알 수 있다. 이러한 프로스포츠팀의 조직변화와 성과 간의 역동에 관해 실증하여 제시함으로써, 프로스포츠팀의 조직변화가 어느 시점에 더 효과적인지를 분석하였다는 점에서 이론과 실무적 시사점을 지닌다.
