The mandatory installation of the ECDIS (Electronic Chart Display and Information System) became an important navigational equipment for navigation officer. In addition, ECDIS is a key component of the ship's digitalization in conjunction with various navigational equipment. Meanwhile, cyber-attacks emerge as a new threat along with digitalization. Damage caused by cyber-attacks is also reported in the shipping sector, and IMO recommends that cybersecurity guidelines be developed and included in International Security Management (ISM). This study analyzed the cybersecurity hazards of ECDIS, where various navigational equipment are connected. To this end, Importance-Performance Analysis (IPA) was conducted on navigation officer using ECDIS. As a result, the development of technologies for cyber-attack detection and prevention should be priority. In addition, policies related to 'Hardware and Software upgrade', 'network access control', and 'data backup and recovery' were analyzed as contents to be maintained. This paper is significant in deriving risk factors from the perspective of ECDIS users and analyzing their priorities, and it is necessary to analyze various cyber-attacks that may occur on ships in the future.

The following research was conducted to encourage residents in urban areas to move to rural areas, and to improve the residential environments in those rural areas. Current policies for rural village development Project were analyzed, and policy implications were proposed. Residents in rural villages participated in a 12-question survey that asked their priorities prior to moving to the area, and factors contributing to resident satisfaction. Importance and Performance Analysis (IPA) was performed to present potential development strategies in the construction business. As a result, 'natural environment and landscapes' had the highest priority and satisfaction, whereas 'lack of public transportation and accessibility' and 'road conditions and parking facilities' had high priorities but low satisfaction levels. Thus, it is important to take nature and environment, as well as accessibility into consideration when moving to rural villages. Although this research was based on residents' bias, and the sample area was limited, these conclusions still offer important policy agreement provide of future rural villages location selection and establishment of land use planning.

Purpose: In this study, the Drenzer facility, which is a facility installed to prevent the spread of fire caused by fire in adjacent buildings in the fire prevention zone, was analyzed legally and technically. We confirmed the uncertainty of the Building Act and the Fire Protection Act, and suggested the revision of the necessary standards. Method: Although the Drenzer facility is a building facility, it is actually applied in the field of firefighting, so the Delphi analysis was conducted on a panel composed of architectural experts and firefighting experts in the first, second, and third rounds to find the issuses and important facility component elements. Finally, the IPA(Importance-Performance Analysis) analysis was conducted to identify the importance of the elements that need to be revised. Result: Delphi analysis was carried out for experts on various components of Drenzer equipment in the first, second, and third rounds, and it was found that the survey items of the head, detector, and other facilities of the Drenzer equipment are valid items to identify problems. The IPA analysis indicated that the revision of the standards for Drencher head was necessary as a priority. Conclusion: In this study, it was possible to confirm the opinions of experts through Delphi analysis on the legal and technical problems of Drencher facilities, and it was confirmed that among the components of the Drencher facility, the revision of the head-related regulations is required as a priority.

This study examined the differences of importance and performance perception level among the food & beverage festival attributes of visitors participating 'Daegu Chimac Festival' and also conducted importance-performance analysis (IPA) of food & beverage festival Attributes. The results were as follows: firstly, food & beverage festival attributes were grouped into four factors such as 'sanitation environment', 'food taste and variety', 'food quality and supplementary service' and 'food purchase convenient.' Secondly, the 4 factors and 21 items of festival attributes showed statistically significant differences in their levels of importance and performance. Finally, results of the questionnaire survey of 322 visitors at '2018 Daegu Chimac Festival' indicated that 'food purchase convenient' and 'food taste and variety' were important to visitors and had high performance. Although attributes related to 'food quality and supplementary service' had an low importance and low performance, and also 'sanitation environment' had an low importance and high performance in the IPA results, they were identified as the key determinants affecting food & beverage festival' success.

The results of study are as follows. First, it was shown that they shared the perception that human rights in residential care home were important. Second, it was shown that there was a statistically significant difference in the gap analysis between the level of performance and importance of human rights area in residential care home. Third, the results of analysis using IPA matrix were presented in order to establish an action strategy making it possible to overcome a gap between importance and performance.

Recently, highway service becomes a very important service in highways. Highway service is considered as a positive interaction method between highway service companies and customers. From this perspective, this study was to investigate the relationships between influencing factors of highway service and user satisfaction. And, this research was to examine the differences between importance and performance of highway service factors using IPA (Importance-Performance Analysis). The result of this study has categorised the 22 highway service attributes into seven highway service selection factors: food, culture, kindness and health, products, large space, employee and Phone, facility. Using IPA, this study has compared the importance and performance of highway service selection factors, as perceived highway service customers. The empirical findings suggest that strategic framework using IPA gives guidelines that improve effectiveness of highway service.

Recently the use demand for national parks has been rapidly increased due to the change of leisure patterns in Korea. The intensive use of national parks, however, can cause serious management problems both in resource conservation and in visitor satisfaction. In order to prepare the effective management plan for the sustainable use of national parks, it is essential to evaluate the visitor satisfaction. The purpose of this study is to provide important information for the management strategies for Namsan and Tohamsan national parks in Kyongju. Importance-performance analysis (IPA) was adopted to analyze the visitor expectation and satisfaction. The questionnaire survey was performed to the 420 visitors of the three sites (Namsan Sam-reung, Namsam Yong-jang, and Tohamsan) that are the most popular areas in Kyongju national park. The IPA for the 18 satisfaction items shows that all the values for importance are higher than those for performance in the three sites. This results indicates that visitors' satisfactions for the 18 items are lower than their expectations. The IP matrix reveals that the management effort should be concentrated on the educational opportunities for nature and culture in Yong-jang, on the convenient access to park in Sam-reung. and on the availability of cool drinking water in Tohamsan. Based on the results, several suggestions for the management strategies were summarized for the three sites in conclusion.

Procurement and lifting scheduling of modules and resources in modular construction, where modules that are manufactured from factory are delivered and assembled on site, is a crucial factor that determines the efficiency of the whole construction. However, previous studies have barely acknowledged the significance of resource procurement process and lifting of modules in modular construction. Therefore, this research aims to derive factors that are in need of improvement for successful implementation of procurement and lifting efficiency, and visualize them according to their importance and performance on improvement through IPA(Important Performance Analysis).
