Each enterprise and public organizations is initiating its preparation to push the envelope on establishing digital transformation strategy; originally, companies and organizations had mainly put an emphasis on efficient operating control while today they also highlight a take-off to a new business model. However, it is evident that there is a lack of study on what kind of preparation and process they should go through. The purpose of this study is to analyze its factors academically and verify them in the frame of C. Wheeler’s, “NEBIC: A Dynamic Capabilities Theory for Assessing Net-Enablement.”. Some processes to verify are developed in the combination of the expectancy theory as well as the contingency theory so called. There are several hypotheses examined in this study. First, future technical knowledge gives influence on recognizing business opportunities, and recognizing business opportunities influences innovation practice. Second, expectation for innovation performance on digital transformation brings about will for innovation, and this arouses innovation practice. Third, the employee’s recognition of the top management’s on promoting innovation about digital transformation acts as a moderating variable on each step to lead innovation performance. This study carries a crucial meaning for each corporation in terms of preparation for digital transformation, and implications on a new direction for the future.

Most enterprises today work on digital transformation projects to cope with uncertainties caused by the rapid change and cutting-edge technology. The key point is they need to take a novel approach on new projects for high performance. In this context, there is a growing interest in utilizing agile method; however, many studies on Impact of Digital Transformation on the Results of Innovation do not deal with agile methodology. The research specifies the case of Seoul Metro, regarded as best-practice on digital transformation, based on the agile way of working. The case study is based on in-depth interview with Seoul Metro’s executives and employees, and the interview is analyzed using keywords from the 12 Agile Principles. Thus, among the 12 Agile Principles, Motivation and Trust, Face-to-face Interactions, Continuous Attention to Technical excellence and good design, Self-Organizing Team contributed the most to successful digital transformation projects. In addition, based on Requirements Uncertainty and Technical Degree of Uncertainty, they carry different kinds of traits. For instance, the higher the uncertainty toward requirements and required technology is, the more technological development pace is maintained. Given the conservative nature of public corporations, it is necessary to adopt the agile way of working, such as improving employees’ technological capabilities and allowing teams to be organized within themselves, in a bid to produce successful innovation outcome.

Vancomycin eye drop is useful for the ophthalmic infection by methicillin-resistant Staphylococcus aureus(MRSA), methicillin-resistant Staphylococcus epidermidis(MRSE). At neonatal intensive care unit(NICU) in Asan medical center, when we culture the eye discharges of patients and find MRSA, we prepare vancomycin eye drop 30 ㎎/mL and treat the patents with it for two weeks. Until now, we stored vancomycin eye drop under refrigeration and used it within 10 days. But the data for the stability of vancomycin eye drop is not available. So in this study, we intended to evaluate the stability of vancomycin eye drop. We prepared six bottles of vancomycin eye drop with artificial tears to 30 ㎎/mL and evaluated the stability. Three samples were stored under refrigeration and the other three at room temperature. We analysed the contents of vancomycin by HPLC and evaluated osmolarity, pH over 4 weeks. The solutions retained a mean of at least 90% of the initial drug concentration for 21 days under refrigeration and 10 days at room temperature. No substantial change in pH was observed during the study. The osmolarity was maintained similarly. No contamination was detected during the study period. In conclusion, it can be recommended that we use vancomycin eye drop up to 3 weeks from preparation.
