Nowadays the Project Management is increasingly adapted into almost all the fields in business management processes among leading companies both in Korea and overseas. However its actual practices are rare to be found. Among the Project Life Cycle, this report covers the real cases of the PMBOK knowledge areas in NPP Architect Engineering. The areas of the Construction, Start-up and Operation will be exception of the cases. By way of analyzing the KEPCO ENC's Processes/Procedures/Systems and the ones in PMBOK Guide, this report will show the contents in the PMBOK Guide is rather practical than theoretical. Meanwhile, implications whether the conclusions of this report might be applied to other industries such as general construction, non-nuclear plants, etc. should be left behind to follow-up studies.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

Purpose - This study investigated the demographic characteristics of retirees who sought not to be reemployed or join an organization but, instead, to be self-employed. This study verified self-employment by regional and/or educational features to determine the self-employment factors and the policies required. Research design, data, and methodology - Models and hypotheses were used to verify the conversion into self-employment depending on retirees' demographic characteristics. This study investigated regions according to precedent studies and used SPSS 18.0 as follows. First, frequency was used to investigate the general characteristics. Second, a factor correlation analysis was done. Results - Hypothesis 1, which stated that, "retirees with low educational background often start a self-employed business," was significant. Hypothesis 2, which stated that, "retirees in metropolitan areas frequently start a self-employed business," was significant. Hypothesis 3, which stated that, "retirees in a megalopolis frequently start a self-employed business," was significant. Conclusions - A preliminary startup education was needed to lessen the losses. Retirees should have preliminary knowledge of actual self-employment conditions to be given a startup education.

The IT outsourcing industry has been widespread for decades since the growth of the system integration industry stagnates and companies need to curtail expenses and improve the quality of IT services. According to previous studies on the success factors of the IT outsourcing, its transition phase is significant because of continuity of business and the handover of knowledge. Since a transition phase consists of several projects, but its goal is different from general projects, it needs special and professional management. Therefore, recent IT outsourcing business starts to introduce PMO (project management offices), of which success strongly depends on the competencies of the PMO. However, there are only few studies on which competencies of the PMO are important. In this paper, we suggest an evaluation model of transition PMO competencies derived using the repertory grid technique and the analytic hierarchy process. Additionally, we compare the differences between the views of several stakeholders on the importance of the competencies.

Rapid technological advancements and widespread adoption of smart phones in recent years provide students with new opportunities for getting knowledge and making researches in innovation century. As the penetration of smart phone devices in education increases, there is a large growth in the use of these devices especially among the youth. In spite of increasing importance of smart devices in education, the significant features of these technology devices for general learning have not been experientially addressed. In this study we are going to investigate the comparison of smart phone devices and find the necessary conditions for using mobile devices as an educational tool by a conjoint method. There will be five attributes: screen size, batter type, mobile OS, memory capacity and price. By surveying we got the results which showed us the respondents' desire of using specific smart phone; thus, we defined that screen size attribute is the most important device characteristic.

The purpose of this study is to explore the effect of different types of simultaneous presentation (i.e., reviewer information, textual and visual content, and similarity between textual-visual contents) on review usefulness and review enjoyment in online restaurant reviews (ORRs), as they are interrelated yet have rarely been examined together in previous research. By using Latent Dirichlet Allocation (LDA) topic modeling and state-of-the-art machine learning (ML) methodologies, we found that review readability in textual content and salient objects in images in visual content have a significant impact on both review usefulness and review enjoyment. Moreover, similarity between textual-visual contents was found to be a major factor in determining review usefulness but not review enjoyment. As for reviewer information, reputation, expertise, and location of residence, these were found to be significantly related to review enjoyment. This study contributes to the body of knowledge on ORRs and provides valuable implications for general users and managers in the hospitality and tourism industries.

It is well known that market transactions do not lead to social optima when externalities exist. Given that previous studies such as RICARDO-AEA(2014) have identified various types of external costs, we must take their magnitudes, or externalities in general, into account in order to make toll prices to achieve social optimum. Little has been done on estimation of externalities in road uses in Korea, to the best of our knowledge. We suggested to use the contingent valuation method (CVM) to estimate overall social benefits and applied it to estimation of benefits of road kill prevention as a pilot study. Our empirical model has considered heteroskedasticity explicitly and its estimation result was that individual drivers were willing to pay 147 KRW on average in addition to current toll prices for prevention of road kills. We provided general discussions of externalities in road use and various internalization measures.
