The main purpose of this study was to provide a development plan for the Korean billiard industry. The methods utilized in this study include web-crawling through Python, review of literature, non-participatory observation of events, interviews with experts and the marketing specialists in the area of Korean billiard industry, and a case study on European professional billiard league. This study found the following results. First of all, Korea Billiard Federation(KBF) was recommended to initiate the effective membership program in which would be the main revenue stream for KBF. Second, KBF is to organize a new type of league with five divisions including upper divisions (1·2 division) for elite athletes and the sub divisions(3․4 divisions) for amateur athletes with the systematic process of promotion and relegation.

Purpose: To report the clinical characteristics and the results of a series of patients treated with various strabismus surgery techniques for Duane retraction syndrome (DRS). Methods: Thirty-eight patients with DRS undergoing surgical treatment were retrospectively reviewed. In all patients, ocular alignment, abnormal head posture and ocular motility disturbance were assessed both preoperatively and postoperatively. The patients were treated with appropriate horizontal muscle recession, Y-splitting combined with horizontal muscle recession, medial rectus recession and lateral rectus resection. Results: The incidence of DRS was greater in females and in the left eye. Type 1 was the most common, and esodeviation was seen most frequently in the primary position. The esotropic patients with DRS turned their faces toward the affected eyes, while the exotropic patients with DRS turned away from the affected eyes. The deviation in the primary position was reduced from an average of 15.0 prism diopters (PD) to 1.5PD. The face turn was reduced from an average of 17.5 degrees to 1.2 degrees. Conclusions: The primary deviation and abnormal head posture found in DRS can be improved by proper preoperative evaluation and adequate choice of surgical methods. 목적: 수술적 교정이 필요하였던 듀안안구후퇴증후군 환자를 대상으로 임상 양상과 수술 결과에 대하여 알아보고자 하였다. 대상과 방법: 듀안안구후퇴증후군 환자 38명(40안)을 대상으로 수평근 후전술 단독시행, 수평근 후전술 및 Y형 분리술, 내직근 후전술과 함께 외직근 절제술을 시행하고 수술 전후의 사시각, 이상두위, 안구운동장애와 내전시 과도한 상전 및 하전, 안구후퇴 여부를 후향적 으로 분석하였다. 결과: 여성(73.7%)과 좌안(63.2%)에서 발생빈도가 높았으며, 제I형이 가장 많았다(84.2%). 내편위가 가장 흔하였고 얼굴돌림은 내사시의 경우 환안쪽으로, 외사시의 경우 환안의 반대방향으로 나타났다. 술 전 사시각은 15.0±5.9 프리즘디옵터(PD)에서 술 후 1.5±2.3PD로 감소하였으며, 이상두위 역시 술 전 17.5±6.6°에서 1.2±2.3°로 감소하였다. 결론: 듀안안구후퇴증후군 환자에서 술 전 검사를 통한 적절한 수술방법 선택으로 안구편위, 이상두위의 호전을 확인할 수 있었다.
