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.

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.

`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.`

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.

李鍾柱(Jong-Joo Lee),車載祥(Jae-Sang Cha),申明澈(Myong-Chul Shin) 대한전기학회 2006 전기학회논문지 D Vol.55 No.6

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.

CVM 을 활용한 TV 프로그램 관광경제가치추정 - 드라마 및 여행예능 프로그램을 중심으로 -

이종주(Jong-Joo Lee) 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.7

대중매체에 노출된 장소는 잠재여행객에게 호기심과 기대를 형성하여 행동을 유도하며 대중매체를 통해 반복적으로 노출된 장소는 시청자에게 영향을 미친다. TV 프로그램 중에서 가장 큰 파급력을 지닌 장르는 드라마이고, 드라마와는 다른 특성의 몰입을 제공하는 리얼리티프로그램은 시청자의 여행지 선정에 영향을 준다. 관광지처럼 시장에서 평가되지 못하는 대상의 가치추정에 주로 이용되는 것이 가상가치평가법(CVM)이다. 본 연구는 CVM을 활용하여 드라마와 여행예능프로그램을 대상으로 촬영지의 경제적 가치평가를 실시 한 후 두 프로그램 촬영지의 연구결과를 비교분석 하였다. 드라마와 여행예능 프로그램 촬영지 지불의사측정을 위해 선형로짓과 로그로짓분석을 실시하였으며 지불가능금액을 도츨하였다. 연구결론은 드라마와 여행예능 프로그램 촬영지를 방문하는데 필요한 여행비용이 증가할수록 방문의사는 감소하였다. 드라마와 여행예능 프로그램 촬영지 방문시에 지불가능한 금액이 일반 당일여행 평균소비금액보다 높았으며 드라마가 여행예능프로그램 촬영지 방문보다 지불가능한 금액이 모두 높았다. Places exposed to mass media induce behavior by forming curiosity and expectations for potential travelers. The places reported through mass media influence viewers. Among TV programs, the most influential genre is drama, and reality programs that provide immersion with different characteristics from dramas influence viewers choice of destination. CVM is mainly used for estimating the value of objects that cannot be evaluated in the market, such as tourist destinations. This study conducted an economic valuation of filming locations for dramas and travel entertainment programs using CVM, and then compared and analyzed the research results of the two filming locations. Linear and log logit analysis were performed to measure the willingness to pay for the filming location of the drama/travel entertainment program, and the payment amount was derived. The conclusion of the study is that as the travel cost required to visit the filming location of the drama/travel entertainment program increased, the intention to visit decreased. The amount payable when visiting the filming location of the drama/travel entertainment program was higher than the average consumption amount for a day trip, and the amount payable for the drama was higher than that of visiting the filming location of the travel entertainment program.

이종주(Jong-Joo Lee),정민의(Min-Eui Jung) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.9

21세기의 신성장 동력으로 여겨지고 있으며 최근에 급격한 양적 및 질적 성장을 하고 있는 의료관광이나 우리나라가 제공하는 의료관광 상품이 아직 의료 관광객의 필요에 충분히 부응하지 못하는 측면이 있다. 이의 해법을 의료관광속성에 관한 연구에서 찾고자 한다. 여기에 2000년 이후 꾸준히 성장세를 유지하고 있는 한류에 대한 관심의 정도가 의료관광에 영향을 미치는지도 확인한다. 이를 위해 5가지 가설이 설정되었고 가설검증을 위해 설문을 통한 실증분석을 실시하였다. 실증분석을 위해 SPSS 20.0 통계프로그램을 활용하였고, 설정된 가설은 검증결과 모두 채택되었다. 가설검증결과 한류에 대한 관여도는 의료관광속성, 만족도 및 행동의도에 영향을 미쳤으며 의료관광속성도 만족도 및 행동의도에 영향을 미침을 확인하였다. Medical tourism which is considered a new growth engine of the 21th century has been rapidly developing in the both quantity and quality. However, medical tourism products offered by our country are not enough to be differentiated according to the need of medical tourists. This study tried to search for the solutions in the medical tourism attributes. This confirmed whether the involvement of Hallyu(Korean wave) which has been growing steadily since 2000 affects medical tourism or not. For these purposes, there were 5 hypotheses set and empirical analysis was conducted through a survey. SPSS 20.0 statistical program was used for the empirical analysis and the established hypotheses were all adopted as a result of verification. It was thus confirmed that the involvement of Hanrye affected medical tourism attributes, satisfaction and behavioral intentions. Also, medical tourism attributes affected satisfaction and behavioral intentions.

관여도 및 템플스테이 만족도 요인이 행동의도에 미치는 영향

이종주(Jong-Joo Lee),윤지현(Ji-hyun Yun) 한국콘텐츠학회 2012 한국콘텐츠학회논문지 Vol.12 No.10

템플스테이는 한국의 역사와 문화를 체험할 수 있는 종교관광이며 문화관광으로 급격한 양적 성장을 하여 왔으나, 이제는 질적 성장의 필요성이 절실하며 본 연구는 이러한 목적을 달성하고자 진행되었다. 관광측면에서의 기존 템플스테이 연구들은 템플스테이 참여자의 만족과 행동의도에 대한 영향 연구이거나 국내·외 참가자들의 차이분석이 주를 이루어 왔다. 이와 달리 본 연구는 참가자들의 종교적 관여 정도 및 만족도와 행동의도인 구전 및 재방문과의 영향관계를 확인하고자 하였다. 이 영향관계의 규명을 위해 3개의 가설을 설정하여 실증분석을 실시하였고, 실증분석 결과 설정된 3개의 가설이 모두 부분적으로 채택이 되었다. Temple stay has increased fast in the quantitative part recently and it is tourism goods with cultural value as a kind of religion tourism. It is thought that the qualitative development is accompanied with quantitative development at this time. So, in order to increase qualitative improvement, it is needed to confirm mutual relationships among religious involvement, satisfaction factors of performance and behavior intentions of people who takes part in temple stay. Also, this paper confirms whether statistical characteristic of population affects religious involvement or not. 3 assumptions are established for these purposes and all of 3 established assumptions are partly adopted through statistical analyses.
