Purpose: Orbital hematic pseudocyst is the localized accumulation of organized blood-breakdown products within a fibrous capsule, and is known to be typically located subperiosteally. We report a case of orbital hematic pseudocyst in the intraconal space. Methods: A 51-year-old man visited our clinic, complaining of injection and bruise of his right eye one month before. On the orbit MRI, a mass assumed to be benign was detected in the intraconal space of his right orbit. After several months of follow-up, a decrease of visual acuity and visual field defect were detected in his right eye. Excision of the mass was done through lateral and medial orbitotomy. Results: Histologic examination showed the accumulation of blood-breakdown products within a fibrous capsule, and the mass was diagnosed as a hematic pseudocyst. Conclusions: When a well-demarcated and slowly growing mass is detected in the intraconal space of the orbit, the possibility of hematic pseudocyst should be considered.

Purpose: To evaluate long-term changes in visual acuity, fundus findings and complications in X-linked juvenile retinoschisis. Methods: A retrospective chart review was conducted on 48 patients diagnosed with X-linked juvenile retinoschisis and followed for a minimum of 12 months. Results: Forty-eight males (mean age 5.7 years) were followed for a mean of 6.3 years. The mean visual acuities were 0.14 at the initial and most recent examinations without significant change (p=0.67). Macular abnormalities were seen in all eyes. Macular lesions varied as follows: decreased foveal reflex (12.5%), typical foveal schisis (77.1%), atrophic change (5.2%), and macula-involving peripheral schisis (5.2%). When patients had different macular findings, the mean visual acuities were significantly different among groups (p≤0.005), except those between the atrophic change group and the macula-involving peripheral schisis group. Peripheral schisis was detected in 66% of patients. The fundus findings were stationary during the follow-up period except in complicated cases with vitreous hemorrhage (15.6%). Conclusions: X-linked juvenile retinoschisis causes bilateral visual acuity loss, affecting maculae. In uncomplicated cases, changes in visual acuity and fundus findings were not significant during the follow-up period.

`Purpose: To investigate the clinical features and treatment results in eyelid sebaceous gland carcinoma. Methods: A retrospective chart review was conducted on 28 adult patients that were histopathologically diagnosed with eyelid sebaceous gland carcinomas from April 1981 to March 2005 in Seoul National University Hospital. Results: Among the 28 cases of eyelid sebaceous gland carcinoma, 9 cases (32.1%) had evidences of local invasion or metastasis at the initial diagnosis. Surgical resection was performed in the 27 cases (96.4%), and conjunctival cryotherapy, surgeries, such as maxillectomy, parotidectomy, and neck dissection, or radiation therapy were combined in cases of local invasion or metastasis. In the 19 cases of the localized tumor group, there were 2 cases (10.5%) of recurrence after an average 30 months of follow-up. The locally invasive tumor group (2 cases) showed 1 case of recurrence after 12 months of follow-up. In the 7 cases of the distant metastasis tumor group, tumors in 3 cases (42.9%) could not be controlled, and 3 cases (75.0%) showed recurrence after an average 45 months of follow-up. Conclusions: Eyelid sebaceous gland carcinomas with local invasion or metastasis afford higher potential for treatment failure, so early diagnosis is crucial. Because recurrence is possible, even when the tumor is completely removed, the extent of the tumor should be examined thoroughly and microscopically.`

Objective : The therapeutic impact of tumor resection in glioblastomas is poorly defined and still questionable. Therefore, we conducted the current study to verify the role of tumor resection in the treatment of these highly malignant tumors. Methods : A retrospective study was performed(1990-1999) to compare the treatment results of surgical resection plus radiotherapy(130 patients) with those of stereotactic biopsy plus radiotherapy(19 patients) in glioblastomas. Only adult patients with supratentorial, de novo glioblastoma located in one lobe were included. Survival time/rate was analysed with Kaplan-Meier method, and prognostic variables were obtained from the univariate log-rank test and the multivariate Cox's proportional hazards model. Results : The resection group and the biopsy group did not differ in terms of age, gender, duration of symptoms, presenting symptoms, tumor location, tumor side, tumor size, and the frequency of midline shift. Patients in the biopsy group more often were found to have worse preoperative Karnofsky performance status(KPS)(p=0.001). On univariate analysis, age, KPS, and tumor side were associated with survival(p=0.0053, 0.0001, and 0.0331 respectively). Median survival time and 1-year survival rate were also statistically improved by tumor resection ; resection group - 13 months and 61.2%, and biopsy group - 8 months and 19.7%, respectively(p=0.0001). In patients with midline shift of the tumor, resection was highly effective comparing to biopsy(p=0.0001), but in patients without midline shift, external beam radiation alone was as effective as tumor resection(p=0.0605). Other prognostic variables did not affect survival. On multivariate analysis after variable selection, survival was independently associated with KPS(p=0.001), but not the surgical resection(p=0.2837). Even in biopsy group with midline shift of the tumor, survival rate was not different from that seen after tumor resection(p=0.3505). Conclusions : Radiotherapy alone was as effective as tumor resection plus radiotherapy in patients without midline shift of the tumor. Although there was not statistically significant, tumor resection looked like effective in patients with midline shift. For supratentorial, lobar glioblastoma patients without mass effect of the tumor, biopsy with radiotherapy is one of rational treatment strategies. We consider that tumor resection should be performed in patients with pretreatment midline shift.

이종주 ( Jong Joo Lee ) 대한관광경영학회 2015 觀光硏究 Vol.29 No.6
2012년 방한 의료관광객의 24%를 차지하여 방한 의료관광객 배출국 1위가 중국이며 앞으로도 꾸준한 성장이 예측되는 시장이다. 문화체육관광부·한국관광공사(2013)는 중국인들은 한국의 의료관광상품 중에서 성형관광상품을 선호한다고 밝혔으나 동시에 의료관광객 배출국 중 1위를 차지하고 있는 중국의 성형관광객들은 한국의료관광에 대해서 여러 가지 불만족을 표출하고 있다고 하였다. 본 논문은 Kano이론을 근거로 한 Vavra의 수정 IPA를 가지고 중국인 성형관광객들에 의해 제기되는 불만족 문제의 해법을 찾고자 한다. 선행연구 분석을 통해 3가지 연구방법이 설정되었다. 연구방법 1. 대응표본 T검정을 통해 성형관광속성의 중요도 및 만족도를 확인한다. 연구방법 2. 수정 IPA matrix 상의 성형관광속성의 위치를 확인한다. 연구방법 3. 회귀분석을 활용하여 성형관광속성과 전반적 만족도의 영향관계를 확인한다. 제기된 문제를 해결하기 위해 설정 된 연구방법에 따라 연구를 진행하기 위해 설문을 실시한 후 설문분석을 위해 SPSS 20.0 프로그램을 활용하였다. 분석결과 성형관광속성의 중요도와 만족도가 높은 속성을 확인하였고, 수정 IPA matrix 상에서의 성형관광속성의 위치를 통해 성형관광속성의 마케팅적 의미를 확인하였다. 또한 전반적 만족도에 일부 성형관광속성이 긍정적 영향을 미침을 확인하였다. Korea`s medical tourism industry has been emerging as one of the country`s new development engines. According to its medical tourism statistics in 2013, about 24% of all medical tourists who visited Korea in 2012 came from China, the highest of the pack. A report of the Korea Tourism Organization says the Chinese like Korean cosmetic surgery tourism products more than Korea`s other medical tourism products. More and more Chinese are expected to visit Korea for cosmetic surgery tourism, but the Chinese awareness of Korean medical tourism is low, and the Chinese who have experienced it have expressed various forms of dissatisfaction with their experiences. To order to solve these recognized problems, three methods were selected to proceed this research. First, this study confirms the cosmetic surgery tourism attributes valued by the Chinese and with which they have shown much satisfaction in Korea. Second, this study confirms each characteristic of cosmetic surgery tourism attributes through its position on the revised IPA matrix. Finally, this study confirms the relationship between each factor classified after the factor analysis with the cosmetic surgery tourism attributes and the overall satisfaction with them. The SPSS 20.0 program was used to statistically analyze these research themes. The results of these analyses are expected to help set directions for customer service improvement and for the proper supply of customer services vis-a-vis the limitations in time and resources.

이종주(Jong Joo Lee),성재연(Jae Yun Sung),이성복(Sung Bok Lee) 대한안과학회 2017 대한안과학회지 Vol.58 No.4
목적: 청소년을 대상으로 안구표면질환지수(Ocular Surface Disease Index, OSDI) 설문조사를 시행하여 안구건조증 유병률을 파악하고, 안구건조증과 연관된 청소년 생활 행태를 분석하고자 하였다. 대상과 방법: 대전 지역 중학생과 고등학생을 대상으로 OSDI 설문조사 및 생활 행태 설문조사를 실시하였다. OSDI 점수가 13점 이상인 경우 안구건조증이 있는 것으로 정의하였고, 13-22점을 경도, 23-32점을 중등도, 33-100점을 중증의 안구건조증으로 분류하였다. 아울러 1주 동안 전자 기기(휴대폰, 컴퓨터, TV) 사용 시간, 1일 동안 학업 시간 및 수면 시간, 콘택트렌즈, 안경, 가습기 사용 여부를 확인하였다. 결과: 총 332명 중 147명(44.3%)이 안구건조증에 해당되었고, 중증은 54명(16.3%)이었다. 안구건조증 유병률은 여학생(p=0.004), 장시간 전자 기기 사용자(응답자 평균인 1주 15.3시간 기준, p=0.011), 콘택트렌즈 사용자(p=0.001)에서 더 높았다. 전자 기기 사용 시간별 안구건조증 유병률은 1주 14시간 이상인 경우 53.9%, 7시간 이상인 경우 40.2%, 7시간 미만인 경우 33.7%였다(p=0.002). 남학생은 전자 기기 사용 시간이 안구건조증의 위험 인자였고(p=0.027), 여학생은 콘택트렌즈 착용이 안구건조증의 위험 인자였다(p=0.009). 결론: 청소년층에서도 안구건조증 유병률은 높았고, 청소년 생활 행태 중 장시간 전자 기기 사용과 콘택트렌즈 착용이 안구건조증 위험을 높였다. Purpose: To investigate the prevalence and risk factors of dry eye syndrome (DES) among adolescents based on the Ocular Surface Disease Index (OSDI) questionnaire. Methods: A questionnaire survey was conducted on middle and high school students in Daejeon. DES was diagnosed by an OSDI score ≥ 13. According to the OSDI score, DES was classified as mild (13-22 points), moderate (23-32 points), or severe (33-100 points). Additionally, responses to the questions regarding adolescents’ life behaviors including the duration of electronic device use per week (cellphone, computer, TV), study hours per day, sleeping hours per day, contact lenses use, glasses use, and humidifier use were analyzed to determine the associations with DES. Results: Of 332 students, DES was diagnosed in 147 (44.3%), and 54 (16.3%) complained of severe DES. The prevalence of DES was higher in female students (p = 0.004), long-time electronic device users (divided on the basis of the mean value, 15.3 hours per week, p = 0.011), and contact lenses users (p = 0.001). The prevalence of DES was 53.9% in groups with ≥ 14 hours of electronic device usage time per week, 40.2% in groups with ≥ 7 hours, and 33.7% in groups with < 7 hours (p = 0.002). The duration of electronic device use per week was a significant risk factor of DES for male students, and contact lenses use was a significant risk factor of DES for female students (p = 0.009). Conclusions: The prevalence of DES was high among adolescents. Long-time electronic device usage and contact lenses wear were associated with DES and increased the risk of DES.

Power line communication channels are very complicated and models for communication channels vary with the types of electrical equipment, devices and load fluctuations. So, modeling and analysis of power line channels for implementation of power line communication systems is a very important process. Power line channel modeling and simulation are performed based on power system transient simulation models and power system CAD tools to create precise and accurate models. In this paper, a channel modeling and simulation method is proposed for power line communication systems using PSCAD/EMTDC, in which a PN 63 sequence code generator is applied for impulse response of the power line channel in the simulation model.
