In order to derive the success factors of a Mega-scale national project, this study conducted a questionnaire survey on experts participating in the Yongsan National Park development program to obtain critical success factors in the program definition phase. AHP analysis was performed for each category through a survey of experts participating in the definition phase of the Yongsan park development program to derive relative importance. The categories were classified into program strategy, process, and people, and the importance between categories was people, strategy, and process in that order. In addition, as for the 27 critical success factors in the program definition phase, the program manager's competency and leadership, environmental and cultural property survey planning, program management plan preparation, operation and maintenance philosophy, and integrated program office showed high priorities. Therefore, in promoting the Yongsan Park development program, we propose a strategy for selecting and focusing on the critical success factors with high priorities in the program definition phase proposed in this study.

The demands for knowledge in the rapid social change and the competitive environment are being increased day by day. As to reflect the demands, much scholarly and practical work has been done on the topics of Knowledge Management (KM). However, the study of KM in nonprofit organizations (NPOs) is insufficient. This study, while discussing the nature of NPOs, which have the different purposes of existence and characteristics from for-profit organizations, has the purpose of finding out the special strategy for KM in NPOs. Through understanding the characteristics and the status of NPOs, this study suggests that that the interorganizational KM is the method to lead successful KM in NPOs. And the critical success factors (CSFs) are presented in the three major factors, such as the systematical, the interorganizational and internal consideration factor for organization. This not only provides the successful KM strategy of NPOs but also enlarges the understandings about interorganizational KM.

Although Enterprise Systems (ES) have promised major strategic benefits and process improvements from business and technology integration, their implementation has been plagued by a high failure rate and difficulty in realizing the promised benefits. For the purpose of understanding implementation failures, previous studies have focused on identifying critical success factors (CSFs) for information systems implementation. However, there has been little research on how these CSFs actually lead to successful results. In this study, based on process theory, we examined the process of ES implementation by explaining how the factors of ES implementation influence each other and how interaction among them produces results. Based on a failure case, we then developed a process model of ES implementation thus allowing us to explain the process of ES implementation. The proposed model facilitated an understanding of how repeating patterns of ES failure can be reversed. This model can be used for guiding new ES implementation projects.

The awareness of the high-value industry for container terminal leads competitiveness of container terminals to keep high fiercely. In regards to competitive factors of container terminal, the most important point among several factors is seemed to be the speed of container loading and unloading on quayside. In container terminals in Korea, the productivity shows big difference even though its condition is similar to each terminal. The objective of this paper is to find the critical factors of container terminal productivity, which is dependant upon the capability, quantity of quay crane, transfer vehicle, and so on. For this purpose, we have researched related literatures, and collected data about container terminals in South Korea. Furthermore, we tested sensitive analysis to evaluate the extent of productivity by changing independent variable. And then we established the regression model to evaluate which factor has had the biggest impact on productivity. The results of this paper can give terminal operators guideline to improve productivity.

Project-based joint ventures are often used in the construction industry to assemble an organization that meets a client's project needs and matches or exceeds the capacities of competitors. The joint venture / partnerships provides the means for a firm to quickly add resource, political, technical, or other required strengths that will increase project acquisition. This paper sets out to study the types of joint ventures, different issues or problems while having joint ventures and the critical factors that contribute to successful joint ventures. A questionnaire was designed and administered to survey the issues and present practices of joint ventures in the South Florida construction industry. Along with the questionnaire, personnel interviews were also conducted to get first hand knowledge about the subject matter. The results are presented in the paper. These results specifically identify the overall practice of joint ventures in South Florida as well as indicate the most significant factors leading to failure or success of these ventures.

Analytical hierarchy process (AHP) is a potential decision making method in management that can be used in project management as well. Lack of productivity is perhaps the number one problem confronting in the construction industry. There are numerous factors which affect the productivity of a construction project, so it is necessary to find out the critical factors giving birth to productivity. In this paper, construction productivity is taken as example for the demonstration of the AHP application to find out the critical productivity factor in which the Level 1 is taken as selection of critical productivity factor, Level 2 as construction parties and Level 3 as productivity factors group. The outcome of this study is beneficial to the entire constructional professionals for applying the AHP.

Background: We aimed to analyze the factors predicting the diagnostic performance of flexible bronchoscopy without guidance in peripheral lung lesions that are endoscopically invisible. Methods: This was a retrospective study conducted in St. Paul's Hospital, The Catholic University of Korea, between January 2007 and March 2013. We included all patients who received bronchoscopy during this period. The analyzed variables were age, sex, the etiology of the lesion, lesion size, distance from the pleura, and presence of the bronchus sign. We used multiple logistic regression analysis to identify the significant independent factors associated with diagnostic yield. Results: We included 151 patients in this study. The overall diagnostic yield was 58.3%. The sensitivity was 43.2% for malignant disease and 78.1% for benign disease. The benign lung lesions (p<0.001), lesion size (p=0.015), presence of the exposed type of bronchus sign (p<0.001), and presence of cavitary lung lesions (p=0.005) were factors influencing the yield of flexible bronchoscopy by univariate analysis. In a multivariate logistic regression analysis, the exposed type of bronchus sign and benign lung lesions were independent predicting factors (odds ratio [OR]: 27.95; 95% confidence interval [CI], 7.56-103.32; p<0.001 and OR, 4.91; 95% CI, 1.76-13.72; p=0.002). Conclusion: The presence of the exposed type of bronchus sign and benign lung lesions are determining factors of the diagnostic yield in flexible bronchoscopy in evaluating peripheral lesions that are not endoscopically visible.

Purpose : This study was intended to investigate the structural relationship among empowerment, self-efficacy, job motivation, autonomy, critical thinking, job-satisfaction, burnout, and self-achievement. In addition, we tested the moderating effect of the career period on the influence of empowerment. Methodology : The structural equation model was used to test the causal relationship between factors, and t-test, ANOVA, descriptive statistics are applied to analyze the research data. Findings : The result of this study shows that the structural model that is the empowerment encourages the self-efficacy, job motivation, autonomy, and critical thinking, also these factors affect the self-achievement through both the job-satisfaction and burnout is acceptable according to the goodness of fitness indices. In addition, we show that the career period moderates the influence of empowerment on the self-efficacy, job-motivation, and autonomy, but not critical thinking. Usually, the shorter the career period is the higher the influence of empowerment is. This moderating effect means that to give proper empowerment to lower position nurses encourage them, and prevent from burnout. Therefore, they feel job-satisfaction and finally self-achievement. Practical Implications : The empowerment helps the nurse to activate self-efficacy, job motivation, autonomy, critical thinking. Hence, these factors decrease burn-out but increase job satisfaction. Finally a sense of self-perfection increase.
