Background: Clinical classification of onychomycosis is commonly divided into 4 clinical types but some authors suggest 5 clinical types. Pathogenic fungi, treatment response and prognosis of onychomycosis are different dependent upon the clinical type. Therefore, suitable clinical classification is necessary before treatment. Objective: The primary aim of this study was to investigate the incidence and distribution of 4 clinical types of onychomycosis: distal and lateral subungual onychomycosis (DLSO), superficial white onychomycosis (SWO), proximal subungual onychomycosis (PSO), total dystrophic onychomycosis (TDO). The secondary aim of this study was to clarify the DLSO, the most common type of the onychomycosis, by dividing it into 4 subtypes. Methods: The diagnosis of the patients were confirmed by more than 1 positive test among KOH smear, fungus culture, histopathologic test and KONCPA test. Total 817 onychomycotic nails of 589 patients (331 males, 258 females) who visited Department of dermatology, Catholic University, St. Mary hospital between January, 1999 and December, 2006 were included. Clinical photographs and charts of the patients were thoroughly reviewed and divided into 4 clinical types and 4 clinical subtypes in case of DLSO. Results: 1. Out of 817 nails, 623 (76.3%) fell into DLSO and 82 (10.0%) TDO, 65 (7.9%) SWO, 47 (5.8%) PSO, respectively. 2. 623 nails diagnosed to be DLSO were further divided into 4 clinical subtypes: 243 (39.0%) edge types, 211 (33.9%) distal types, 104 (16.7%) linear types and 65 (10.4%) lateral types. 3. 315 males with DLSO were further divided into 4 clinical subtypes: 130 (41.3%) edge types, 96 (30.5%) distal types, 54 (17.1%) linear types and 35 (10.6%) lateral types. Females in the same group also exhibited same ranks in terms of prevalence. 4. Out of 457 big toenails, there were 193 edge types (42.2%), 141 distal types (30.9%), 77 linear types (16.8%) and 46 lateral types (10.1%). Out of 105 other toenails, there were 42 distal types (40.0%), 28 edge types (26.7%), 19 linear types (18.1%) and 16 lateral types (15.2%). Conclusion: DLSO composed of 76.3% of onychomycosis were further classified into 4 clinical subtypes. Further clinical studies will be necessary to evaluate the value and efficacy of this subclassification in deciding the treatment methods and presumption of prognosis.

Optical Storage 산업에서 LG전자의 성공

안효상,이동현 한국국제경영관리학회 2010 국제경영리뷰 Vol.14 No.2

본 사례에서는 光 저장장치(optical storage) 산업에서 LG전자가 어떻게 선발 기업을 추격하고 선두자리를 차지할 수 있었는지 그 요인들을 살펴보았다. LG전자는 특허 기술, 핵심 부품, 연구개발 인력, 거래선 기반 등이 절대적으로 취약한 상황에서 사업을 시작하여 CD 시대는 물론 DVD 시대에도 성공적으로 선발기업들을 추격하였고, 결과적으로 세계 1위의 자리를 차지할 수 있었다. 특히 DVD 시대에는 일본 히타치와의 합작 사업을 통해 조기에 기술을 확보하였고, 이를 바탕으로 다양한 포맷을 함께 사용할 수 있는 신제품을 조기 출시함으로써 사업의 주도권을 확보할 수 있었다. 하지만 본격 시작된 블루레이 디스크 시장에서 LG전자는 아직 선두업체가 아니었으며, 새로운 도전이 기다리고 있었다. The purpose of this case is to analyze the strategy for LG electronics, as latecomer to catch-up first movers in optical storage industry. In the lack of patents, core components, R&D talents and contracts with PC makers, LG electronics started the optical disc drive business, catched up innovators and finally took the leading position in CD and DVD era. Especially in DVD era, LG electronics could absorb the core DVD technology earlier through joint venture with Hitachi. LG electronics took an industry leadership by rapid introduction of new product, so called Super-Multi combined various DVD formats. But LG electronics was not the leading company in Blu-Ray Disk era and faced new challenges.

글로벌 光저장장치 산업에서 후발기업 전략에 관한 연구

안효상,이동현 글로벌경영학회 2011 글로벌경영학회지 Vol.8 No.1

본 논문에서는 후발기업의 전략을 추격(catch-up)전략과 추월(leapfrogging)전략으로 구분하여 각각의 성공 요인들을 살펴보았다. 특히 글로벌 光 저장장치 산업에 후발로 참여한 LG전자가 선발기업인 소니를 추격하고 궁극적으로는 추월한 사례 분석을 통해 연구 명제들을 도출하였다. 사례 분석에 의하면후발기업이 선발기업을 효과적으로 추격하기 위해서는 기반 기술의 확보가 필요하며 이를 위해서는 보유한 관련 지식을 활용하거나, 전략적 제휴를 통하여 외부 지식을 효과적으로 흡수하였다. 또한 후발기업이 선발기업을 추월하기 위해서는 제품 혁신이 필요하며, 제품 혁신은 기존에 확보하고 있는 관련 지식의 새로운 결합을 통하거나, 핵심 부품과 관련된 핵심 기술의 내부화에 의해 이루어졌다. This paper dealt with key success factors after dividing the strategies that latecomers can adapt into catch-up strategy and leapfrogging strategy. In the global optical storage industry, LG Electronics as a latecomer catched up with first mover and finally leapfrogged SONY. Through the case analysis of LG Electronics, some research propositions are suggested. The case showed that for latecomers to effectively catch up with first movers, latecomers should be equipped with fundamental technological skills using their technological knowledge accumulated over the years, or absorb external knowledge through strategic alliances. In order to leapfrog first movers, latecomers should need product innovation which could only be realized by combining the existing knowledge in a new way or by internalizing core technology with regard to core components.
