Strengthening Risk Evaluation in Existing Risk Diagnosis Method
Shui Yee Wong,Kwai Sang Chin,Dawei Tang 대한산업공학회 2010 Industrial Engineeering & Management Systems Vol.9 No.1
An existing risk diagnosing methodology (RDM) diagnoses corporate risk for product-innovation projects. However, it cannot evaluate and compare the risk levels of multiple alternatives in the product development stage. This paper proposes a modified risk diagnosis method to fill the gap of risk evaluation in selections of innovative product alternatives and the application of the method will be also illustrated by a case problem on alternative selections in electrical dimmer designs. With RDM as the foundation, a modified RDM (MRDM) is proposed to deal with the problem of selecting innovative project alternatives during the early stages of product development. The Bayesian network; a probabilistic graphical model, is adopted to support the risk pre-assessment stage in the MRDM. The MRDM is proposed by incorporating the risk pre-assessment stage into the foundation. By evaluating the engineering design risks in two electrical dimmer switches, an application of the MRDM in product innovation development is successfully exemplified. This paper strengthens the existing methodology for RDM in innovative product development projects to accommodate innovative alternatives. It is advantageous for companies to identify and measure the risks associated in product development so as to plan for appropriate risk mitigation strategies.

Innovation fuels organizations evolving them to withstand rapid changes in markets and challenges from competition. While diversified concepts of innovation are examined, a generic framework for managing organizational innovation is established to portray the notion in a methodical approach. Substantiation of the determinants for organizational innovation is carried out in order to examine the framework against the practical situation. Subsequently, expectations and actual accomplishments of the determinants for organizational innovation from the industry are determined so as to understand the industrial view towards the framework. This paper summarizes the empirical findings of a survey of organizational innovation with a sample of 208 electronic and electrical manufacturing companies in the Greater Pearl River Delta (GPRD), China. On one hand, the survey findings confirm the readiness of the generic framework from the practical perspective of the industry. On the other hand, rankings are obtained for the expected importance and company accomplishment of the determinants for organizational innovation, namely in the areas of management leadership and commitment, employee capability and attitude and strategy development for innovation. The improvement area is also verified by the shortcomings of the expectation in comparison to the company accomplishment in each determinant. Meanwhile, it is believed that a directional attitude towards the determinants can facilitate the accomplishment of the determinants of organizational innovation. Further results will be generated from a more in-depth analysis of variables. The confirmed framework will be further developed into an assessment system for organizational innovation with the support of best practices in each determinant.

Purpose: To investigate the long-term results (at least 5 years of follow-up) of the mini asymmetric radial keratotomy(MARK) and corneal cross-linking (CXL) combined intervention, also known as the ‘Rome protocol,’for patients with progressive stage I and II keratoconus and contact lens intolerance. Methods: This was a retrospective observational case series. Fifteen eyes of 12 patients were evaluated, witha mean follow-up of 6.9 years. To assess the efficacy and stability of the MARK + CXL combined protocol,best spectacle-corrected visual acuity, mean pachymetry, and mean keratometry were recorded preoperativelyand at least 1, 3, and 5 years postoperatively. Statistical analysis was performed using the R platformand involved the Wilcoxon signed-rank and Kruskal-Wallis non-parametric tests. Results: Best spectacle-corrected visual acuity improved for all patients, from 0.46 ± 0.69 logarithm of theminimum angle of resolution (20 / 60) to 0.15 ± 0.69 logarithm of the minimum angle of resolution (20 / 30, p =0.0006), while mean pachymetry increased in 93% of patients, from 442.80 ± 61.02 to 464.50 ± 62.72 μm (p= 0.003). Lastly, mean keratometry improved in 87% of patients after 6.9 years of observation from 48.82 ±5.00 to 43.25 ± 3.58 diopters (p = 0.008). No intraoperative or postoperative complications were observed. Conclusions: The MARK + CXL combined protocol was effective in treating keratoconus by halting cornealthinning and bulging. In addition, this procedure significantly improved visual acuity based on long-term follow-up data. Analysis of data from a larger cohort of patients would be useful to support these findings.
