Changes have occurred in the professional capabilities of the construction project managers after the global financial crisis. As representatives of construction companies and projects, construction project managers have full responsibility over a construction project. Throughout its life cycle, from design through construction to completion, the business capabilities of such managers are regarded as critical elements in the changes in the country's construction economy. Therefore, this study aimed to determine the main capabilities of current construction project managers, and to analysis of its competitiveness using Important-Performance Analysis(IPA). The results of IPA were as follows; (1)capability to win new contracts and capability to collect information of new project are needed for external relation competitiveness, (2)gerentocratic management mind-set and active breakthrough are needed for internal project management competitiveness, and (3)capability to predict issues and self-improvement are needed for self discipline competitiveness. However, this work is still considered to provide the basic data that can help Korean construction companies who plan to educate the project manager's strengthen their medium and long-term capabilities.

In general, drivers need a self-interest information to decide their routes. So, non-governmental sectors, such as Internet Portal Company, make and provide user-oriented contents for drivers in a hurry. But, VMS which is the typical public media always provides traffic-information for drivers without weighting personal characteristics and considering transportation conditions. So in this research, we searched importance and preference of traffic-information contents as IPA(Importance-Performance Analysis)result. We can draw the conclusion that the improvement of traffic-information contents focused on users(drivers) is needed. Specially, we proposed the strategy of VMS according to traffic conditions.

This study endeavors to propose factors that should be intensively managed by using an IPA model to analyze the strengths of military logistics. Based on the improvement measures, we constructed a questionnaire with 5 points of Likert scale and analyzed the importance and satisfaction through SPSS 23. Examination of several evaluation factors revealed 'expansion of and modernization storage facilities' as the most important factor, 'merger and abolition of regional logistics work' (3.56) had the highest satisfaction level. Factors involving the expansion and modernization of the storage facilities showed the largest difference between importance level and satisfaction level, at 2.01. This indicates the necessity for an overall review of the expansion and modernization of storage facilities related to military logistics. This study aims to identify the areas that should be improved firstly in military logistics and concentrate on management to create more effective results. Thus it suggests that this study has a concentration on management for the streamlining of military logistics.

The purpose of this study is to prioritize the importance of urban railway service quality through statistical analysis. This was done to maximize customer satisfaction by providing customers of urban railway services (including LRT), operated by the local government, with a better customized service quality. It was hoped that this project would boost the need for public transportation by increasing customer satisfaction, which would eventually lead to more profitable revenue. The results of validity certification of expectations and perceptions before and after the use of government funded urban railway and private sector invested urban railways show that there are gaps for 18 items for the government funded urban rail projects (p<.01), while there is no significant difference for 2 items between expectation and perception (p>.05); private sector invested urban railway projects show differences for all 20 items (p<.001). Therefore, IPA analysis is conducted to improve the service quality; this should lead to a remedy that focuses on service quality. The findings of this study will contribute to providing management strategies for boosting customer satisfaction and creating revenue through customized service quality in the urban railway operating industry (including LRT), which is currently suffering from chronic deficits.

Most accidents at construction sites are occurring in vulnerable groups such as new workers, foreign workers, and elderly workers. These vulnerable workers often lead to accidents due to the lack of awareness of risks. Therefore, in order to reduce accidents, it is necessary to pay attention to and manage vulnerable workers. This study attempted to identify the level of safety awareness and safety management priorities for vulnerable workers through IPA analysis. New workers should be able to adapt to the field as soon as possible, and foreign workers were found to need frequent check-ups due to language communication problems. In the case of older workers, it was analyzed that it was necessary to check their health and to check whether they were performing other tasks than the prescribed ones.

The purpose of this study was to derive policy priorities for fostering the biopharmaceutical industry. In this study, the urgency and importance of the policy to foster the biopharmaceutical industry in Gyeonggi-do was investigated, and the priorities of the policy in the biopharmaceutical industry were analyzed through IPA analysis. As a result of the study, the top priority support tasks for the biopharmaceutical industry promotion policy were 'R&D support', 'Expert training', and 'commercialization support'. As a result of deriving policy priorities for each biopharmaceutical sector, 'R&D support' and 'Expert training' were found to be high in common, and differences in policy priorities for each industry such as cell therapy products and advanced bio-convergence products were confirmed. Also, as for the policy demand, R&D funding support, clinical trial support, and commercialization funding support were found to be high. Based on these results, the government's policy to foster the biopharmaceutical industry was supported with a focus on 'R&D support' and 'Expert training', and policy implications were drawn that customized support is needed in consideration of the characteristics of each industry field.

This research has been carried out for assessing the competitiveness of the major Asian airports based on the quality of service provision. Five airports were selected for evaluation: Hong Kong, Singapore Changi, Tokyo Narita, Bangkok Don Muang, and Seoul Incheon International Airport. For evaluation of these selected airports, AHP and IPA techniques were applied. Five main factors were defined through a literature review of previous studies: concreteness, convenience, economic efficiency, respondency, and accessability. Hong Kong International Airport had the strongest airport in the Asian region, followed by Incheon International Airport. The least competitive airports were Bangkok and Tokyo Narita International Airport in regards to users' perception for the provision of services at the airport.

An intelligent personal assistant (IPA) is a software agent that assists people to perform basic tasks or services for an individual by commonly providing information via natural language. In spite of the versatile capabilities of the IPA to answer a user's simple information-based queries, such as the weather and driving directions, the actual usage rates for IPA services are limited to date. In this research, to evaluate the factors affecting the intention to use IPA, we develop an empirical model based on technology acceptance model, innovation diffusion theory, and IS success model. Afterward, we collect 203 questionnaires from actual users of IPAs. Finally, the structural equation model validates the causal relationship between the constructs of the model. Consequently, the innovation characteristics of IPA drawn from innovation diffusion theory, namely, relative advantage, compatibility, observability, all exerted a positive influence on perceived usefulness. Furthermore, information quality, a quality characteristic of IPA obtained from DeLone and McLean's IS success model, presented a positive effect on perceived usefulness and perceived ease of use. Finally, the perceived intelligence of IPA displayed a positive influence on perceived usefulness and ease of use. This characteristic was also a major factor that can increase the intention to use the IPA. Given these research findings, this study is significant for identifying factors that may influence the intention to use the IPA by providing strategic guidelines to relevant business operators and establishing an integrated model.

This study has systematically classified established the agricultural management risks from the agricultural company's position and analyzed their counterplan situation in order to seek measures to counteract this. The AHP & IPA technique were used as an analysis method concerning the evaluation results. The counterplan situation was deduced through an interview investigation of 112 farmers who produce cabbage, white radish, onion, garlic, chili, and 6 other such items in order to stereotype the risks. If the agricultural companies' management capacity is raised in accordance to the risk counterplan deduced from this study, and the risks of agricultural management activity are avoided ahead of time or counter means are activated, we can anticipate the stabilization of agricultural management.

The purpose of this study is to provide basic data for the development of pre-parent education program by grasping parent role recognition, educational needs and readiness of unmarried men and women. The subjects were 196 unmarried male and female students from K-do. Data were collected from November 1st to 20th, 2018, and analyzed using IBM SPSS WIN/21.0 to get frequency, percentage, average, standard deviation, t-test, ANOVA, sheffe-test, paired t-test, and IPA matrix. The average score of recognition of social pre-parent role was $3.41{\pm}0.27$ (out of 5 points), educational needs was $3.48{\pm}0.41$ points (out of 4 points), and educational readiness was $2.65{\pm}0.57$ points (out of 4 points). educational needs being higher than educational readiness. Through IPA matrix analysis, the area to be strengthened was 'family relation or parent role', and 'self understanding' was the area to encourage putting effort into other evaluation attributes. The area where no further effort is needed and needs improvement in the future was 'spouse selection and marriage', and 'pregnancy and childbirth' and 'child rearing' were the areas to intensively improve. Therefore, there is a need for establishing a standardized strategy in the area A, which has high degree of readiness and needs. Also, it is necessary to take strategies and countermeasures to raise the readiness of area C with low degree of readiness and needs, rather than accepting it as an unnecessary area of further effort input.
