Forecasting probability or likelihood of technology development success has been a crucial factor for critical decisions in technology management such as R&D project selection and go or no-go decision of new product development (NPD) projects. This paper proposes an analytic network process (ANP) approach to forecasting of technology development success. Reviewing literature on factors affecting technology development success has constructed the ANP model composed of four criteria clusters : R&D characteristics, R&D competency, technological characteristics, and technological environment. An alternative cluster comprised of two elements, success and failure is also included in the model. The working of the proposed approach is provided with the help of a case study example of MRAM (magnetic random access memory) technology.

As the business environment is rapidly changing with globalization and complexity of information flows, the uncertainty is also very increased for project environment. Although many studies have been conducted to find out the critical factors for project success, there still exist different views to define project success. Furthermore, implementing success formula for one project does not necessarily guarantee a success for another project since there are other elements that impede the success of project. In this regards, it is imperative to examine what are the barriers to project success. This study aims to examine the barriers that impede the success of project. Past literature was thoroughly reviewed to collect and develop a preliminary list of elements that affected project performance negatively. Experts were interviewed to refine the list and the final list of the measurement items were developed. A survey questionnaire was developed with the final list of measurement items, and a survey was conducted on the practitioners with project experience. After the survey, an exploratory factor analysis was conducted on the final list to extract the component dimensions which in turn formed the group of project barriers. The exploratory factor analysis provided ten factors, which are difficulty of process management, failure of project feasibility analysis, cost overruns and lack of cost benefits, unclarity project plan, strategic consistency error, stakeholder conflict, inaccuracy of requirement definition, disturbance of communication, technical environment change, negative attitude of top management.

The recent information society is affected by new technologies including EC(Electronic Commerce), CALS(Commerce At Light Speed), EDI(Electronic Data Interchange), telecommuting and teleconferencing. The research goal of this paper is to identify major failure factors to reduce the dysfunction of EC and to suggest possible strategies that overcome those obstacles. The research methodologies of major failure factors are very similar to those of critical success factors which were widely used in MIS research areas. Ideally EC provides the possibility of a win/win situation for vendors and consumers. A survey study was performed using questionnaires. The factor analysis was performed to identify failure factors. Several hypotheses were set up to identify the major failure factors to reduce the dysfunction of EC. The regession analysis was performed to test those hypotheses and to understand the relationships between the major failure factors identified and the performance variables such as satisfaction, usage, and usefulness. Finally, the paper suggests alternatives to activate EC in terms of regulations, social rules, a technological model, etc.

Background and Objective Endoscopic airway dilation is the primary treatment for pediatric subglottic stenosis (SGS) due to its feasibility and non-invasiveness. The aim of this study is to evaluate the risk factors for the failure of endoscopic airway dilation in pediatric patients with SGS. Materials and Methods This study reviewed medical records of 38 pediatric patients had endoscopic dilation from a single and tertiary referral center, retrospectively. The success of the endoscopic dilation procedure was defined as no dyspneic symptom without tracheostomy or laryngotracheal reconstruction. Demographic profiles, underlying disease, and Myer-Cotton SGS severity grade were recorded. Success rates and risk factors for the failure of treatment were analyzed. Results The SGS patients with severity grade I was most common. After mean 1.8 numbers of procedures, there were 23 patients (60.5%) in the success group and 15 patients (39.5%) in the failure group. Age, sex, underlying diseases, and SGS severity grade were not significantly different between two groups. In patients who had multiple endoscopic procedures, the failure group showed SGS deteriorated after procedures in 66.7%, compared to 11.1% of the success group. In multivariable analysis, a long-term intubation (≥1 month) was identified as an independent risk factor for failure of endoscopic dilation procedure. Conclusion Although endoscopic dilation procedure is safe and effective for the management, repetitive endoscopic dilation may not give clinical benefit in patient with long-term intubation. Other airway procedures must be considered in those group of patients.

This study explores multiple variables of an OTT service for discovering hidden relationship between rating and the other variables of each successful and failed content, respectively. In order to extract key variables that are strongly correlated to the rating across the contents, this work analyzes 170 Netflix original dramas and 419 movies. These contents are classified as success and failure by using the rating site IMDb, respectively. The correlation between the contents, which are classified via rating, and variables such as violence, lewdness and running time are analyzed to determine whether a certain variable appears or not in each successful and failure content. This study employs a regression analysis to discover correlations across the variables as a main analysis method. Since the correlation between independent variables should be low, check multicollinearity and select the variable. Cook's distance is used to detect and remove outliers. To improve the accuracy of the model, a variable selection based on AIC(Akaike Information Criterion) is performed. Finally, the basic assumptions of regression analysis are identified by residual diagnosis and Dubin Watson test. According to the whole analysis process, it is concluded that the more director awards exist and the less immatatable tend to be successful in movies. On the contrary, lower fear tend to be failure in movies. In case of dramas, there are close correlations between failure dramas and lower violence, higher fear, higher drugs.

본 연구는 로저스(1995)의 혁신확산이론 중에서 소비자의 설득 과정에서 중요한 요소인 혁신의 특성에 관한 여러 요인 중 상대적 이익에 대한 신제품의 실패 사례를 분석하였다. 상대적 이익은 여러 혁신 제품의 특성 중에서 구매자의 채택 의도에 가장 큰 영향을 끼치고 있는 요인이기 때문이다(Holak and Lenmann, 1990). 6개 기업의 신제품 실패 사례 분석 결과 이들 제품은 공통적으로 기존 제품에 대하여 상대적 이익이 부족하였다. 상대적이익이란 경제적 의미에서 측정되거나 사회적 우위 요소, 편리도, 만족도 등으로 측정되는 요인이며 적합성, 복잡성, 관찰가능성, 시용가능성 등 다른 요인들에 비해 가장 중요한 요소이기 때문이다. 결국 신제품을 소비자들에게 설득하기 위해서는 기존 제품들에 비해 상대적 이익이 중요한 성공 요인임을 알 수 있었다.

Purpose: The aim of this retrospective study is to evaluate survival rate of implant and bone formation, to analyze failure contribution factor. Material and Methods: A total of 52 consecutive patients(35 male, 17 female, mean age 49 years) with 104 osseous defects were treated during the period from October 2004 to June 2007 with a simultaneous or staged GBR approach using non-resorbable or resorbable membranes combined with autogenous bone grafts or xenograft(Bio-Oss, Bio-cera, BBP). Result: A total of 32(30,8%) of 104 GBR-treated sites failed the bone formation and a total of 5(5.6%) of 89 implants were removed. Early exposure of the membrane has significantly affected bone formation(p<0.05). Non-resorbable membrane showed more exposure of the membrane and low success rate of bone formation than resorbable membrane(p<0.05). There were no difference between success rate of bone formation and using autogenous bone or graft materials. There were no statistically significant difference between success rate of bone formation and smoking or using PRP. Mandible showed more success rate of bone formation than maxilla(p<0.05). Conclusion: Early exposure of the membrane, membrane type and maxilla/mandible type have influence on success rate of bone formation during GBR.

The Korean government has implemented the policy for merging 141 health insurers into Korean Unified Health Insurer (KUHI) in July of 2000. The unification of multiple insurers will definitely effect the stability of financial management, equity of premium burdens and efficiency of administrative management. However, it is difficult to predict what forms the far-reaching effects of the unification would take. Thus, pursuing the unification may be express as a huge policy experiment. In order to lead the unification, which lies on a crossroad between success and failure, to the road of success, we need to infer the problems and obstacles predicted in the step-wise processes of merging organizations, finances and the systems of computing premium, and come up with the effective means to maintain the stability of financial management, to improve the equity of premium burdens and to increase the efficiency of administrative management. Thus, I first described the changes of the Korean medical insurance system, and analyzed the performances of self-employed medical insurance 1 year after the integration of societies in October of 1998. At the base of examining the stability of financial management, equity of premium burdens and efficiency of administrative management, I predicted the problems and obstacles that could occur after the unification of the multiple medical insurers, and proposed a few ways of leading the unification of the multiple medical insurers in Korea to success. The most worried factor is that insurance finance would become unstable since the expansion of premium revenues is not easy because raising the premium for all Koreans is to be difficult. In addition, the unification of insurance finance could weaken the insurer's efforts for declaring real incomes of the self-employed and increasing the collection rate of premiums from them. This weakening would be the decisive factor of lowering the equity of premium contributions between the self-employed and employees. And bureaucratization and rigidity that are unavoidable in a gigantic unified organization could lower the efficiency of administrative management. Furthermore, by having 3 labor unions in the unified organization, it is possible to experience frequent difficulties and discords among the unions and between the unions and organization. Thus, when smooth pursuing of the unification of multiple insurers gets difficult, the social expenses derived from the failure would eventually end up on all Koreans. The unification is to be performed after coming up with the ways to eradicate these worries, so that the unification of multiple insurers would step onto the road of success.
