The competition aspect of business has been transformed from competition among companies to competition among ecosystem, and has been grown to platform based business, which is defined as ecosystem among business. Coming to the spotlight with the advantages of platform business combined software and hardware like Apple, platform business have been emerging in many fields. In this research, we define platform and platform based business, and then review related researches. After this, we review four representative research methodologies which are Yin(2011)' s case analysis research, Eisenhardt(2007)' s case analysis research, Romano etc' s web based qualitative data analysis method(2003), and Creswll(2010)' s open coding technique. And then, we suggest this research' s natural methodology combined with the advantages of four research methodologies. Based on our research methodology, we choose three high commercialized categories, which are smartphone platform business, social platform business, and search engine platform business. And then, we choose seven companies in three categories with success cases & failure cases, and analysis each case in perspective of our research methodology. And then, we suggest critical success & failure elements. Based on our findings, we suggest three strategic elements for the longevity of platform based business. Finally, we suggest the limitations of our research and further research issues.

The purpose of this study was to investigate the kinematic comparison between successful and failed trials of Lopez vault techniques in male gymnastics. The subject, an Olympic gold medalist, was YHS (age: 27 years, height: 1.6 m, and mass: 53 kg) and fourteen high speed motion capturing cameras were used for data collection. The 26 reflective sensors were attached on major anatomical positions and 15 segment-body model was used to calculate the kinematic variables. According to results, the contact duration of the spring-board for successful trial(ST) was longer and that of failed trial(FT) and the range of motion of knee joint for ST was greater than that of FT. The movement times during pre-flight between ST and FT were same, but the movement time of horse contact period for ST was shorter than that of FT. The ST showed a longer movement time during post-flight and the longer horizontal distance than those of FT. Conclusively, YHS needs to approach the horse with a higher position of the body and higher incidence angle, as well as make faster twist angular velocity in an attempt to achieve ST.

This study aims to analyze the causes of a new product failure by using system safety methods, focusing on the case of Samsung Galaxy Note7. However, when analyzing the causes of a product failure, if only technical problems are too emphasized, it is likely to miss other more meaningful causes of a failure. Thus, we claim that the root causes of a product failure should be identified in a broad perspective of integrated systems that include non-technical as well as technical elements. With this viewpoint, we investigated the failure of Samsung Galaxy Note7, by using Root Cause Analysis(RCA) and Fault Tree Analysis (FTA). The results showed that it is necessary to address not only the technical issues but also other non-technical issues, such as a very impetuous launch of a new product due to a very tough competition in the market. Additionally, we also found that RCA and FTA could be a useful tool for analyzing the causes of a new product failure from the viewpoint of an integrated system comprising technical and management elements.

한 나라의 경제는 자유경쟁원리에 입각한 시장 경제가 주도할 때 발전되어 가지만 자유경쟁체제는 때로 독점기업을 탄생시키고 이들 독점기업의 횡포 때문에 오히려 국민들에게 불편을 초래하는 시장의 실패가 발생한다. 한편, 철도와 같은 사회간접자본은 대자본이 소요되고 조직ㆍ규모가 방대하기에 시장에 맡기기보다는 정부가 이를 직접 운영하는 사례가 많다. 우리나라가 물론 이에 속한다. (중략)

데이터웨어하우징에 대한 열광적인 분위기와는 달리 실패 사례가 늘고 있으며, 시간이 지날수록 수렁에 빠져드는 느낌을 지울 수 없다. 하지만 푸시기술이 총체적 위기에 빠진 데이터웨어하우징에 새로운 생명력을 불어넣고 있다. 푸시기술은 데이터웨어하우징에 긍정적이고 주요한 충격을 가하게 될 것이다. 이것은 올 연말경 시도될 예정이며, 1998년에서 2000년에 걸쳐 그 효과가 나타날 것이다.

인터넷 쇼핑몰의 창업 절차가 기존 비즈니스 창업 절차와 크게 달라져야 할 이유는 없다. 하지만, 분명한 것은 비즈니스 조건과 환경이 다르다는 점이다. 결국, 새로운 비즈니스에서 승리하기 위해서는 성공 및 실패 사이트에 대한 철저한 벤치마킹이 필요하다. 바로 이부분이 인터넷 비즈니스 창업 과정에서 가장 중요하게 고려되어야 할 점이다. 디지털경제체제 아래에서, 인터넷쇼핑몰 창업을 위한 모델별 핵심 사례와 절차에 대해 알아본다.

The ultimate goal of this study is to investigate the cases with respect to smart factory that has been introduced by German government. To do this, the study suggest implications for manufacturing version 3.0 that is one of manufacturing revolution agendas in Korea. The main point of smart factory is the convergence between manufacturing and information and communications technologies such as CPS(Cyber-Physical Systems), MES(Manufacturing Execution Systems), 3D Printer, AI(Artificial Intelligence), and so forth. It is hard to accomplish a complete manufacturing automation. In fact, German government had experienced the failure in pursuing the smart factory agenda. But now the agenda is gradually realized by a variety of success stories from German. Thus, this study is to investigate the well-known success stories that came from German.
