본 연구는 선행연구를 바탕으로 스크린골프장을 이용하는 소비자들이 지각하는 브랜드 증거, 브랜드 신뢰, 이용만족, 재방문의도 간의 영향 관계를 파악하고자 하 였으며, 선행연구의 이론적 근거를 토대로 2022년 4월 20일부터 5월 3일까지 약 2주간에 걸쳐 인터넷 설문조사 전문기관을 통해 서울, 경기의 수도권에 거주하는 소비자 300명을 대상으로 자료를 수집하였고 분석에 활용할 수 없는 11부를 제외 한 총 289부를 최종분석에 활용하였다. 연구결과를 살펴보면, 브랜드 증거가 브랜드 신뢰와 이용만족에 통계적으로 유 의미한 정(+)의 영향을 미치는 것으로 확인되었으며, 브랜드 증거 중 자아이미지 일치성이 브랜드 신뢰와 이용만족에 가장 많은 영향을 미치는 것으로 나타났다. 또 한 브랜드 신뢰가 이용만족과 재방문의도에 통계적으로 유의미한 정(+)의 영향을 미치고 이용만족이 브랜드 신뢰보다 재방문의도에 더 많은 영향을 미치는 것으로 확인되었으며, 이용만족이 재방문의도에 통계적으로 유의미한 정(+)의 영향을 미 치는 것으로 확인되었다. 이상의 연구결과를 기반으로 스크린골프장을 이용하는 소비자들은 특히 자신의 이미지에 부합하면서 핵심서비스를 잘 갖출수록 브랜드를 신뢰하고 이용만족이 높 아지며, 이를 통해 향후 스크린골프장을 이용하려는 의지가 증가하는 것을 알 수 있다. 따라서 스크린골프장을 이용하는 소비자들에 대한 지속적인 분석 및 세부적 인 고객관리를 통해 차별화된 서비스를 제공함과 동시에 핵심서비스의 지속적인 개발 및 개선 노력이 필요함을 시사하고 있다.

Purpose: To report clinical and laboratory findings of toxic anterior segment syndrome (TASS) in seven patients following cataract surgery with intraocular lens (IOL) implantation. Methods: The medical records of seven patients who underwent cataract surgery associated with postoperative decreased visual acuity, ocular pain, anterior chamber inflammation and corneal edema between Feb 2007 and Nov 2009 were retrospectively reviewed. Results: All patients were over 60 years of age, four patients had diabetes and four patients had cardiovascular disease. Five patients had received hydrophilic IOL, and six patients underwent surgery later in order. All seven patients presented with increased anterior segment inflammation, acute decreased visual acuity, and severe corneal edema an average of 10.4 days (range 1 to 15 days) after surgery. Treatment of the seven patients included intensive topical and oral steroids, and improvement was noted in all patients. Conclusions: The incidence of TASS after cataract surgery was 0.8%, and was significantly higher in cases of hydrophilic IOL insertion (5 of 284 cases, 1.76%) compared to cases of hydrophobic IOL insertion (2 of 581 cases, 0.34%) (p = 0.04). Five of the seven cases presented with TASS at postoperative day 14. Inflammation improved in all patients with steroid treatment. J Korean Ophthalmol Soc 2011;52(6):690-695
갑상샘눈병증에서 안와감압술 전후 외안근 부피 변화의 영상분석: Nunery 분류법 제1형과 2형 비교

Purpose: To evaluate the radiographic volume change in extraocular muscles (EOM) following orbital wall decompression for Nunery type 1 and type 2 thyroid-associated orbitopathy (TAO). Methods: Medical records of 31 orbits in 20 patients undergoing postoperative orbital CT after orbital decompression for TAO were retrospectively reviewed. The patients were divided according to Nunery classifications. A type 1 classification was assigned to patients who had no diplopia and essentially normal versions. A type 2 classification was assigned to patients with restrictive motility loss and diplopia within 20 degrees of the primary position. EOM volumes were determined by the summation of each EOM’s cross-sectional areas in the coronal plane of the CT scans and multiplying the sum by the slice thickness. Main outcome measure was a comparison of EOM volume changes between types 1 and 2 TAO and a relationship between EOM volume and change in proptosis. Results: In type 2 TAO, a significant increase in the volume of the medial rectus muscle, lateral rectus, and total EOM was detected postoperatively (p = 0.044, 0.022, 0.049), whereas no significant changes were found in the EOM’s volume changes in type 1 TAO. The reduction of proptosis after orbital decompression in type 1 TAO was significantly greater than in type 2 TAO (p = 0.025). A significant positive association was observed between the preoperative EOM volumes and the reduction of proptosis following orbital wall decompression (r = 0.505). Conclusions: The postoperative EOM volumes following orbital wall decompression was significantly increased in Nunery type 2 patients who had restrictive myopathy.

Purpose: To compare the changes in strabismus angle and deviation between two groups: a bilateral lateral rectus recession (Group 1) and a unilateral lateral rectus recession in exotropia (Group 2). Methods: A retrospective survey was conducted on 198 patients who had received exotropia surgery in our ophthalmology clinic from September 2003 to April 2007. A total of 116 patients were in Group 1, and 82 patients were in Group 2. Unilateral lateral rectus recession was performed on patients under 25 PD, and bilateral lateral rectus recession was performed on patients above 25 PD. A case of less than 4 PD esodeviation and less than 10 PD exodeviaton was defined as a success and any other case as a failure at the 1-year follow-up visit. Results: The average deviations of the first postoperative month and the first postoperative year were -1.96 D ± 4.75, 2.5 D ± 7.82 for Group 1 and 0.77 D ± 2.87, 5.94 D ± 3.38 for Group 2. Revealing statistical significance between the 2 Groups: Group 1 had 30 failure cases (25.9%) and their 1 postoperative year average deviation was 5.42 D ± 13.97, while Group 2 showed 24 failure cases (29.3%) and their 1-postoperative-year average deviation was 13.0-79 ± 3.04. Group 1 had less strabismus angle and a greater standard deviation than Group 2, as Group 1 had more overcorrection. Among the 30 failure cases of Group 1, 9 were overcorrected and 21 were undercorrected, but all 24 failure cases in Group 2 were undercorrected. Conclusions: The strabismus angle after lateral rectus recession showed a wider variation and a larger difference in bilateral lateral rectus recession than in the unilateral lateral rectus recession.

Objectives : There is a need to develop a data quality management algorithm to improve the quality of healthcare data using a data quality management system. In this study, we developed a data quality control algorithms associated with diseases related to hypertension in patients with diabetes mellitus. Methods : To make a data quality algorithm, we extracted the 2011 and 2012 discharge damage survey data from diabetes mellitus patients. Derived variables were created using the primary diagnosis, diagnostic unit, primary surgery and treatment, minor surgery and treatment items. Results : Significant factors in diabetes mellitus patients with hypertension were sex, age, ischemic heart disease, and diagnostic ultrasound of the heart. Depending on the decision tree results, we found four groups with extreme values for diabetes accompanying hypertension patients. Conclusions : There is a need to check the actual data contained in the Outlier (extreme value) groups to improve the quality of the data.

황규연(Hwang Kyu-Yeon),이경준(Lee Kyung-Jun),정제창(Jeong Je-Chang) 한국방송·미디어공학회 2016 한국방송공학회 학술발표대회 논문집 Vol.2016 No.11
본 논문에서는 기존에 쓰이던 주파수차감법과 다른 새로운 방법을 제안한다. 본 논문에서 다루는 방법은, 특정한 주파수의 대역에서 음성과 잡음의 우세도를 결정하고, 인간의 청각기와 관련된 매스킹 성질을 기반으로 하여 주파수 차감법을 이용해 제거한다. 이에 대하여 다양한 성능 평가를 하였고, 기존의 일반적인 주파수차감법과 비교하여 보다 효과적으로 잡음처리를 할 수 있음을 알 수 있다.
