          다차원척도법(MDS)과 계층분석적 의사결정방법(AHP)을 활용한 패스트 패션 브랜드 이미지 포지셔닝 분석-20대 남성소비자를 중심으로-

          이지범,강원석 이화여자대학교 경영연구소 2017 신산업경영저널 Vol.35 No.1

          The objective of this study is to provide marketing strategies of Fast Fashion brands by analyzing their position in the market. We survey the men whose are in their 20’ after pretesting the four popular Fast Fashion brands. Utilizing MDS(multidimensional scaling) and AHP(analytical hierarchy process), we analyze how Fast Fashion’s brand images are built. Besides, we explain which properties the Fast Fashion brands should focus on to succeed in their business by providing 20’s male customer’s selection properties of clothes. The results of the study are as follows: First, the order of Fast Fashion’s clothes selection properties is price-design-quality of clothes-store-miscellaneous goods-service-advertizement. Second, the result of multidimensional scaling and regression analysis is that Uniqlo has the most attribute-value in price, store, service and advertizement, Giordano has the most attribute-value in quality of clothes and miscellaneous goods, and H&M has the most attribute-value in design. Based on the results, we suggest strategies about how each brand can take advantage of having a good brand image and being competitive. 본 연구는 최근에 많은 인기를 얻고 있는 패스트패션 브랜드의 포지셔닝을 분석하고 이를 바탕으로 패스트패션 기업들에게 적절한 마케팅 전략을 제시하기 위하여 실시되었다. 평소 패션에 관심이 많고 쇼핑을 즐겨하는 20대 초반의 남성들을 대상으로 설문을 시행하였으며, 사전설문을 통해 패스트패션 브랜드 중 가장 인기가 있는 4개의 브랜드를 선정하였다. 선정한 브랜드를 바탕으로 SPSS의 다차원척도법(MDS), 회귀분석을 실시하여 패스트패션 브랜드의 포지셔닝 맵을 그리고 이미지를 분석하였다. 이 외에도, 계층분석적 의사결정방법(AHP)기법을 활용하여 모집단이 어떠한 패스트패션 의류선택속성에 우선순위를 두고 있는지 분석하여 패스트패션 브랜드가 성공을 거두기 위해서 어떤 선택속성에 초점을 맞추어야 하는지 설명하였다. 연구결과는 다음과 같다. 첫째, 패스트패션 브랜드의 선택속성의 가중치는 가격-디자인-품질-매장-잡화-서비스-광고 순으로 나타났다. 둘째, SPSS 다차원척도분석 및 회귀분석 결과, 디자인은 H&M, 가격은 유니클로, 품질은 지오다노, 매장은 유니클로, 잡화는 지오다노, 서비스는 유니클로, 광고는 유니클로가 해당 속성값을 가장 많이 갖고 있음을 알 수 있다. 우리는 이 결과를 바탕으로 각 브랜드별로 시장에서 인지도와 경쟁력을 갖출 전략들을 제시하였다.

          Temsirolimus in Asian Metastatic/Recurrent Non-clear Cell Renal Carcinoma

          이지범,박형순,박세정,이효진,권경아,최영진,김유정,남정모,조남훈,강보들,정현철,라선영 대한암학회 2019 Cancer Research and Treatment Vol.51 No.4

          Purpose Temsirolimus is effective in the treatment for metastatic non-clear cell renal cell carcinoma (nccRCC) with poor prognosis. We aim to investigate the efficacy and tolerability of temsirolimus in treatment of naïve Asian patients with metastatic/recurrent nccRCC. Materials and Methods From January 2008 to July 2017, data of treatment-naïve, metastatic/recurrent nccRCC patients, who were treated with temsirolimus according to the standard protocol, were collected. The primary end-point was progression-free survival (PFS). Secondary end points were overall survival (OS), objective response rate (ORR), and tolerability of temsirolimus. Results Forty-four metastatic/recurrent nccRCC patients, 10 from prospective and 34 from retrospective groups, were enrolled; 24 patients (54%) were papillary type, and other histology subtypes included 11 chromophobes (25%), two collecting ducts (5%), one Xp11.2 translocation (2%), and six others (14%). The median PFS and OS were 7.6 months and 17.6 months, respectively. ORR was 11% and disease control rate was 83%. Patients with prior nephrectomy had longer PFS (hazard ratio [HR], 0.16; 95% confidence interval [CI], 0.06 to 0.42; p < 0.001) and OS (HR, 0.15; 95% CI, 0.05 to 0.45; p < 0.001). Compared to favorable/ intermediate prognosis group, poor prognosis group had shorter median PFS (4.7 months vs. 7.6 months [HR, 2.91; 95% CI, 1.39 to 6.12; p=0.005]) and median OS (9.2 months vs. 17.6 months [HR, 2.84; 95% CI, 1.23 to 6.56; p=0.015]). Conclusion Temsirolimus not only benefits poor-risk nccRCC patients, but it is also effective in favorable or intermediate-risk group in Asians. Temsirolimus was well-tolerated with manageable adverse events.

          기울기 검출에 의한 얼굴영상의 인식의 개선에 관한 연구

          이지범,이호준,고형화 한국통신학회 1993 韓國通信學會論文誌 Vol.18 No.7

          In this paper, robust recognition system for tilted facial image was developed. At first, standard facial image and lilted facial image are captured by CCTV camera and then transformed into binary image. The binary image is processed in order to obtain contour image by Laplacian edge operator. We trace and delete outermost edge line and use inner contour lines. We label four inner contour lines in order among the inner lines, and then we extract left and right eye with known distance relationship and with two eyes coordinates, and calculate slope information. At last, we rotate the tilted image in accordance with slope information and then calculate the ten distance features between element and element. In order to make the system invariant to image scale, we normalize these features with distance between left and righ eye. Experimental results show 88% recognition rate for twenty five face images when tilted degree is considered and 60% recognition rate when tilted degree is not considered. 본 논문은 얼굴화상에서 국부적일 특징점을 추출하여 기울기에 robust하게 얼굴을 인식하는 새로운 알고리즘을 제안하였다. 바른 자세의 영상과 기운 자세의 영상을 받아 2치화를 한 후 라플라시안 윤곽선 검출기를 이용하여 윤곽선 영상을 얻는다. 윤곽선 영상에서 최외각 윤곽선을 제거하고 내부 윤곽선은 위에서 아래방향으로 주사하면서 나타나는 순서에 따라 네 영역을 각각 A, B, C, D영역으로 레이블링하고 기준선을 중심으로 좌우로 영역을 분할하고 좌우 영역을 상하로 분할하여 모두 네 영역으로 나눈다. 좌우 눈간 거리, 눈과 눈썹사이의 거리, 눈과 코와의 거리 등을 이용하여 최종적으로 두 눈을 찾고 두 눈의 중심좌표값을 이용하여 기울기를 구한다. 기울기 정보를 이용하여 기운 영상을 바로세우고 난 후 눈 아래 영역에서부터 탐색하여 코와 입을 찾는다. 각 특징점간 거리를 계산하고 이를 두 눈사이의 거리를 기준으로 정규화하여 영상의 크기에 무관하게 한다. 인식 실험 결과 25명에 대하여 기울기를 고려한 경우 88%의 인식율을 보였고 기울기를 고려하지 않은 경우 60%의 인 식 율을 보였다.

          Tinea Versicolor Mimicking Pityriasis Rubra Pilaris caused by Malassezia globosa

          이지범,배수현,이민영 대한의진균학회 2017 대한의진균학회지 Vol.22 No.1

          Tinea versicolor (TV) is a common fungal skin disease caused by the Malassezia species. This disease usually presents as hypopigmented- or hyperpigmented coalescing scaly macules, papules, patches or plaques on the trunk and upper arms. Herein, we report a rare clinical manifestation of TV in a 29-year-old man presenting with marked follicular, erythematous, and hyperkeratotic papules on the trunk with erythematous scaly macules and patches on the upper extremities with intermittently spared skin. We initially suspected pityriasis rubra pilaris, however, skin biopsy results and mycological examination revealed TV. Polymerase chain reaction-based sequence analysis revealed Malassezia globosa. The patient was successfully treated with oral itraconazole and topical terbinafine.

          Sporothrix schenckii와 관련주에 대한 Random Amplified Polymorphic DNA (RAPD)분석

          이지범,김민,이승철,원영호,김영표 대한의진균학회 2000 대한의진균학회지 Vol.5 No.3

          Background: Sporotrichosis is a common deep cutaneous fungal disease caused by Sporothtix (S.) schenckii. The recent development of polymerase chain reaction (PCR) technology, in particular, arbitrarily primed PCR (AP-PCR) or random amplified polymorphic DNA (RAPD), has greatly enhanced the molecular detection and identification of various pathogenic agents, including fungi. Objective: This study was aimed to differentiate Sporothrix schenckii, and related fungi such as S. schenckii var. luriei, S. flocculosa, S. nivea, Ophiostoma stenoceras, and clinical isolates on the basis of distinct DNA band patterns in the RAPD. Methods: S. schendcii, S. schenckii var. luriei, S. flocculosa, S. niveㅁ, Ophiostoma stenoceras from ATCC and KCCM, and clinical 10 isolates from Chonnam University Hospital were used for RAPD analysis. For RAPD, 3 random primers were used. Genomic DNA was extracted by Liu method. Amplification reactions were performed in volumes of 50 μL containing 10 mM Tris-HCI (pH 8.3), 50 mM KCl, 1.5 mM MgCl2, 0.1% Triton X-100, 200μM dNTP mixture, 40 pM primer, 1 U of Taq polymerase, DNA 20 ng. Results: 3 decamers (5'-TGCCGAGCTG-3', 5'-AGTCAGCCAC-3', 5'-AATCGGGCTG-3') are generated in the RAPD, distinct DNA products from S. schenckii forming characteristic band patterns upon gel electrophoresis. Each random primer amplified characteristic same band patterns in DNA from clinical 8 isolates among 10 isolates, 2 isolates have different DNA band patterns. These results suggest of being a Sporothrix anamorph different from S. schenckii in Korea. Conclusion: With 2 random primers (5'-TGCCGAGCTG-3', 5'-AGTCAGCCAC-3') S. schenckii and related fungi investigated produced distinct DNA band patterns on gel electrophoresis. The RAPD was a very valuable laboratory method for identification of S. schenckii isolates. [Kor J Med Mycol 5(3): 113-119]

          Background : The treatment of facial telangiectasia include microsclerothetapy, laser, and electrosurgery. It is important that the treatment for telangiectasia be relatively risk-free, especially avoiding unsightly scarring. Objective : We evaluated the effectiveness, complications, and recurrence rate of patients with facial telangiectasia treated with microclerotherapy using osmotic sclerosing agent. In addition, we also evaluated the associated factor, the sites of predilection, and types of facial telangiectasia. Patients & Methods : Fifteen patients with facial telangiectasia went treated with microsclerotherapy using osmotic sclerosant(Sclerdex). The procedure was performed at 4 week intervals and on average 2 times. The effectiveness was evaluated by the comparison of photographs monthly during mean 6 months follow-up period. Results: Mean improvement rate was 70% and partial recurrence was observed in 3 cases(20%). Transient bruising(33%), transient pigmentation(7%) and telangiectatic mating(7%) were observed as complications. Conclusion : Sclertherapy with osmotic sclersant(Sclerdex) is safe and moderately effective: became it usually has more than a good response and minimal complications.
