Importance-Performance Analysis(IPA) is a well-known methodology to find the area for improvement. However, the IPA uses different strategies depending on an attribute falls in either 'Concentrate', 'Keep up', 'Possible overkill', or Low priority' quadrant. Problems can occur when attributes locate near the demarcation lines. To solve this problem of IPA, I suggest a modified importance-satisfaction analysis which integrates the Slack(1994)'s diagonal approach and Kano's ASC(Jang et al., 2012) into Yang(2003)'s Importance-Satisfaction model. For this, I investigated 21 smartphone's quality attributes, which adopted from Song and Park(2012)'s study, and conducted a survey of 280 university students for the results of Kano' model and the importance and satisfaction of the quality attributes. The results show that the proposed model enables the business managers to prioritize the quality attributes for improvement through the interpretation on the continuous diagonal line using the Kano's questionnaire only, without acquiring any additional survey for importance of attributes. Accordingly, it is expected that the newly proposed method will diminish the limitation of the existing IPA. In addition, to test the validity of the ASC, this study conducts a comparative analysis between the Kano's ASC and Tontini(2007)'s method to determine the relative importance of quality attributes.

This study aims to identify the dimensions of trade show performance in Iranian trade shows and apply the revised importance-performance analysis. The IPA method integrates two types of indirect importance and a composite I-P mapping using traditional four-quadrants, as well as a diagonal line on a two-dimensional grid. Based on the analysis results, this study presents several suggestions to contribute to the development of the trade show industry. First, it is noted that the dimensionality of trade show performance in a developing country context can be different from that of prior literature. Taking different industry development stages of a show hosting countries, examining the dimensions of each trade show performance with every effort to derive proper exhibitors' implications is necessary. Second, the use of statically-derived importance is recommended while considering respondents' convenience to reduce their time and fatigue when collecting data at the busy booths. Further, applying composite I-P mapping is suggested as an effective diagnostic tool to provide optimal trade show strategies for the exhibitors under the dynamic and ever-changing global business environment.

Gwangju Airport and Muan International Airport are planned to merge in 2021 while the aviation market is suffering an unprecedented prolonged crisis due to COVID-19 and therefore it is necessary to revitalize the airport to keep up with the passenger's demands. The study conducts an empirical research survey on the passengers of both airports regarding the importance, satisfaction, and overall satisfaction to derive a strategic marketing direction. The results show that to establish a strategic marketing direction, an urgent improvement is required for all "Commercial Facility and Diversity," "Rest Facility and Comfort," "Facilities for the Transportation Vulnerable," "Latest Facility" factors, and "Air Route Diversity." On the other hand, it is required to stop further investing and improving in "Publicity and Marketing" and "Flight Schedule". The results of this study demonstrate academic and practical importance through the comparison of two IPA models, based on Gwangju Airport and Muan International Airport before their integration, to provide substantive and meaningful marketing strategies.

Due to the spread of COVID-19, the use of O2O order·delivery applications are becoming very common. Unlike the past, where customers could choose the desired transaction method and channel, these days, where customers' choices are very limited, it is urgent to consider the concept of shadow labor which has been hindered by the convenience and the benefits of order·delivery app. To this end, in this study, the service quality factors perceived by users of O2O order·delivery app and their shadow work attributes were identified, and priorities according to their relative importance and satisfaction level were suggested. In order to fulfill research objectives, first, after collecting user reviews for an O2O order·delivery app, the subject words were derived using topic modeling. Research variables were selected by linking 11 keywords with the concepts of previous studies on service quality of mobile apps and those about shadow labor. Eight variables of usefulness, ease of use, stability, design quality, personalization, responsiveness, update, and presence were selected. Based on 32 measurement items from the variables, a revised IPA was conducted, and finally, 'keep', 'concentrate', 'low priority', or 'overkill' service quality factors are revealed.

The electronic toll collection system(ETCS), is globally used in about 40 countries. In Korea, the Korea Expressway Corporation led the nationwide introduction of the ETC system in 2007 under the brand name of the Hi-pass. Since then, Hi-pass, with its rate of average daily use reaching about 70%, has become an essential facility in Korean expressways. To identify users' perception on Hi-pass (satisfaction, preference, etc.), this study conducted a Modified Importance-Performance Analysis (M-IPA). With this, this study attempted to identify the kind of efforts necessary to enhance current Hi-pass users' convenience and satisfaction. According to the result of M-IPA, the items including "non-stop payment" and "toll discount" are identified as key items that require further improvement. For improvement in the "non-stop payment" item, operations of Hi-pass toll booths appropriate for the demand for Hi-pass use and the selection of Hi-pass booths' locations in consideration of entry and exit lanes need to be improved. In addition, with regard to the "toll discount" item, although toll discount is currently provided to Hi-pass users, thus, PR thereof will have to be strengthened. It is expected that this study will be used as basic data to devise methods of enhancing Hi-pass usage through improvement of Hi-pass users' satisfaction.

This study aims to analyze importance and performance factors on the quality of food service event attributes in participants and organizers, so that it could provide helpful information to build up a detailed marketing strategy and present considerations for revisit increase and more efficient business results as well. Importance on food service event attributes scored a higher level than performance on the whole. Notably, in regard to the attributes of food service event, it was found that respondents put higher stress on vessel(4.10 points), natural seasoning(4.06 points), reservation service(4.04 points), parking service(3.95 points), customer level(3.85 points), organizer's service (3.84 points), polished atmosphere (3.83 points) and taste of food (3.83 points) than anything else. In terms of IPA analysis on food service event attributes, it was important to continuously maintain 'vessel', 'reservation service', customer level', 'sauce taste', 'recency', price', 'chefs fame', etc. Some items such as 'parking service', 'natural seasoning', 'polished atmosphere', 'taste of food', 'see off service', 'cleanliness' are in need of intensive care and operation.

This study provides basic data for finding a plan for future teacher education in the future society by conducting an IPA-analysis of the abilities required for early-childhood who will become talented persons of the future society and the perceptions of early-childhood teachers about the era of the 4th-Industrial-Revolution. The study was conducted with 194 childhood teachers working in early-childhood educational institutions located in Jeju. It used a questionnaire of the demand survey for teacher education development for early-education based on the 4th-Industrial-Revolution. In the era of the 4th-Industrial-Revolution, the capabilities needed for early-childhood were revised and supplemented in 2016 at the World Economic Forum "Jobs Future Report". The frequencies and percentages were calculated to analyze the characteristics of each subject's background variables, the perceptions of early-childhood teachers and teacher education needs, and a t-test was conducted for each item to analyze the difference in importance and performance of early-childhood's competence. In the importance of competence required for infants who become talents for the future, the results showed that early-childhood teachers chose to have a high level of caring-sharing and curiosity-interesting ability. In the performance, they have a high level of caring-sharing and cooperation-communication ability.

Importance-performance analysis (IPA) is a simple and effective technique that can assist practitioners in prioritizing customer attributes to enhance service quality and visitor's satisfaction. The purpose of this study is to use the IPA-Kano model to examine the correlation of visitor's satisfaction and management matters and deduce the management priority. It classifies 14 visiting satisfaction attributes into basic factors (forest environments and staff/information center), performance factors (the natural landscape, trail facilities, forest status, easy access, and historical and cultural resources), and excitement factors (the value of natural monument, educational experiences, and entrance fee) to select the management priority according to the achievement (satisfaction). The management priority according to the performance is staff/information center > easy access > forest environment > trail facilities, historical and cultural resources, forest status, and natural landscape > entrance fee and educational experience > value of natural monument. By considering their performance, it further identifies development priorities for visitor's satisfaction improvement. These priorities allow local governments to deploy scarce resources to improve satisfaction.

It is well known that the Kano model measures customer satisfaction and classifies quality attributes into must-be, attractive as well as one-dimensional. The main purpose of this study is to investigate the dynamics of e-learning quality attributes by applying the proposed method using Kano's satisfaction index in the rapidly changing online learning environment. For this, the current study examined 27 e-learning quality attributes and conducted a comparative study using Kano's results obtained in 2013 and 2020. The result shows that the dynamics of quality attributes suggested by Kano(2001) is confirmed in the case of e-learning. The proposed approach shows better results in terms of Kano's direct classification method, and has potential application areas such as IPA(Importance-Performance Analysis) in the area of risk assemement. Some suggestions for better understanding of the proposed SI-DI diagram are also included in this study.

New manufactural innovation was generated with combination with Do It Yourself(DIY) culture and Information and Communication Technology(ICT). It led people to make their creative idea in real things and share them. This social movement has been called as 'Maker' culture. As maker culture was developed, the places named 'Makerspace' with high-tech equipment and sharing environment have been widely spread and gotten spotlight. Futhermore, makerspaces have been diffused rapidly in Korea; because of its importance for the fourth industrial revolution. However, the operation of makerspaces is not matured as much as its popularity, so problems occurred in operating aspects. The number of related studies is not enough to foster domestic maker culture in Korea. Of that, studies on operation of makerspaces were limited and the quantity of survey sample was insufficient. Therefore, firstly, in this study, operation elements of makerspaces were extracted by literature review. And, survey for examining the extracted elements was conducted to four policy makers and researchers, four makerspace operators and four makers. Final survey was carried out by Importance-Performance Analysis(IPA) method to fifty recipients composed of policy makers and researchers, operators, and makers. In result, importance located above performance in every elements and in-depth interview was followed to understand domestic surroundings and suggest way to invigorate makerspaces in Korea. The suggestion shows as follows. First, online and offline platform for makers should be expanded; second, makerspace should connect private sponsorship with makers or their projects; third, policy direction has to be improved from venturing business to diffusion of maker culture; fourth, basic maker education should be enlarged.
