The quality of service on urban roadways have been evaluated mainly based on such quantitative measures as travel speed and delay. However, in addition to the quantitative aspects, drivers traveling on urban roadways are subject to be influenced by qualitative measures such as aesthetic aspects of the roadway and other drivers' violation of traffic laws. Based on this notion, this study attempts to identify roadway service quality indices, considering both qualitative and quantitative aspects and evaluate the quality of service using the modified Importance-Performance Analysis (IPA), a technique often applied in the field of marketing. The modified IPA is proposed in this study as a way to evaluate the service quality, reflecting the relative performance between study areas and performance indices. A case study is implemented over the Gangnam and Gangbuk areas in Seoul, resulting in identifying the items needed to be improved for each study area.

This article analyzes the obtained data on consciousness survey of disabled and non-disabled pedestrians, and proposes fundamental data for public strategy in order to enhance facilities in subway stations in advance. This paper conduct literature review, new listing survey related to 'The Code for Improvement of Convenience for Moving Vulnerable Pedestrians', and Modified-Importance-Performance Analysis (M-IPA). The results show that disabled pedestrians want enhancement in information facilities as a whole. In addition, the results show that several improvements needs to be applied to accessible sidewalk, to informative notification, to alarm and evacuation system and to toilet for disabled pedestrians. This indicates that disabled pedestrians heavily concentrate on accessibility to subway station and provided information compared with disabled pedestrians.

To understand urban space and make appropriate plans, the integrative analyses considering road and land use simultaneously are required. In addition, studies that involve both horizontal and vertical spaces must be taken into consideration. Therefore, the purpose of this study is to conduct a classification analysis of road network-based land use considering spatial structure. The methods of this study were as follows; first, a space syntax theory considering the structure of road network was introduced for roads. For land use, to consider both horizontal and vertical development densities of residential and commercial buildings were used. And the explanatory power of three variables-Euclidean distance, global integration and length-reflected global integration-were compared. Third, based on road as an appropriate variable, modified-IPA was conducted with land use and the results were categorized into four areas. The proposed method was applied to Gangnam-gu, a CBD area in Seoul, and results were analyzed and visualized using GIS.

The main purposes of this study is to examine a local restaurants menus' importance and satisfaction of the servicescape. Survey was collected by December 1 through December 31 2015, in the region Kijang County. the data from this survey were analyzed by using various statistical techniques including frequency tables, factor analysis, reliability test, and IPA. Results of IPA analysis showed that menu consisted of local products is the highest average value, and it means the local food restaurants need to use the nostalgic marketing techniques. In addition, menus are currently for sale in order to attract continuing foreign tourists as perceived by Busan residents Kijang. Therefore, the local food restaurants need to revive the traditional flavors and recipes coming down area from ancient times. Based on these results, this study will contribute to provide fundamental information for developing marketing strategies especially local food restaurants.

The National Cyber Capability Assessment(NCCA) could be used as meaningful information for improving national cyber security policy because it provides information on the elements necessary for strengthening national cyber capabilities and the level of each country. However, there were few studies on improving cyber capabilities using the NCCA result in Korea. Therefore, we analyzed the result of National Cyber Power Index(NCPI) conducted by Belfer Center of Harvard Univ. by applying modified-IPA method to derive cybersecurity policy agendas for Korea. As a result, the need to set agendas on surveillance and offensive cyber capability and improve the effectiveness of policy implementation for intelligence and defense was drawn. Moreover, we suggested need for in-depth study of each policy agenda deduced from preceding research data as a future tasks. And it is expected to increase practical use of NCCA for domestic policy analysis by developing and using our own NCCA model which considered analysis framework proposed in this study.

본 연구에서는 코퍼스 확률에 기반하여 한국어 표준 발음 생성에 대한 연구를 한다. 기존의 이은영 외 (2005)에서 연구된 규칙기반의 한국어 IPA 발음 변환방식과는 달리 본 연구에서는 음운변환 코퍼스를 바탕으로 표준발음을 변환한다. 이 방식을 위해서 Brill(1995)에서 제안한 변형기반 학습방식이 활용되었으며, 단계적인 처리방식이 아닌 입-출력 대응 방식의 확률적 처리 방식이 제안되었다. 음운변환 방식은 음운규칙에 근거한 처리가 아닌 언어자원인 코퍼스를 활용해서 처리하였다는 점에서 기존의 연구방식과 차이가 있다. 또한, 기존 연구에서는 음운규칙을 단계적으로 적용하여서 입력형이 출력형으로 도출되기 위해서 여러 단계를 거쳤지만, 본 연구에서는 입력형과 출력형의 일대일 대응이라는 점에서 차이점을 보인다.

A number of cities are committed to enhancing the barrier-free (BF) environments. However, no attempts have been made to examine the BF environment design concept by accounting for the universal BF components, which should be improved for providing both disabled people and non-disabled people with better BF environments. With this challenge in mind, this study determines the improvement priorities of BF components for beaches in the city of Busan by investigating the results of satisfaction survey, which was administered to disabled and non-disabled visitors. The modified importance-performance analysis (M-IPA) results show that "sanitation facilities" are the universal BF components having the highest improvement priority. The analysis results also indicate that "access facilities" have the second highest improvement priority for disabled people while "amenity facilities" have the second highest improvement priority for non-disabled people. It is highly expected that the suggested improvement priorities of BF components can be used for policy makers to develop more flexible plans when designing the BF beach.
