The purpose of this study was to investigate the factors affecting the behavior intention of smartphone mobile banking service among tourists. Currently, due to the development of mobile Internet technology and the spread of smartphone all over the world, interest and spread of smart phone based mobile banking is popularized. Thus, we analyzed the relationship among performance expectancy, social influence, facilitating conditions, perceived financial cost, perceived habit, perceived security level, and user's behavioral intention as a dependent variable. In this study, 203 respondents were interviewed about Chinese tourists at Jeju International Airport, and the influence of independent variables was determined by Smartpls 3.0. The results showed that the perceived security level and habit had a positive effect on the behavior intention. Especially, perceived security is a major issue of smartphone-based mobile banking in recent years. This study is meaningful in that it is an analysis of behavior factors of smartphone-based mobile banking service for tourists.

The characteristic of the beta wave among the EEG waves corresponds to the stress area of human perception. The over-bandwidth of the stress is extracted by analyzing the beta-wave correlation between the low-bandwidth and high-bandwidth. We present a KMeans clustering analysis model for unsupervised machine learning to construct an analytical model for analyzing and extracting the beta-wave correlation. The proposed model classifies the beta wave region into clusters of similar regions and identifies anomalous waveforms in the corresponding clustering category. The abnormal group of waveform clusters and the normal category leaving region are discriminated from the stress risk group. Using this model, it is possible to discriminate the degree of stress of the cognitive state through the EEG waveform, and it is possible to manage and apply the cognitive state of the individual.

With the advent of multicultural society, many countries have come to the point of considering a fundamental revision or review of their previously established national identity and social constitution principles. This situation often generates conflicts and controversies between advocates of tradition and promotors of multiculturalism. In this article we will look at the case of France and Brazil and discuss how these two countries maintain, discard or fundamentally modify their traditional social integration model in the face of the multicultural challenges(racism, racial discrimination and integration/coexistence of immigrants of different cultural backgrounds), and examine the controversial aspects surrounding it. In particular, focusing our eyes on racial/ethnic statistics debates in both countries, we will try to compare the cases between that of adoption of multicultural alternative model(Brazil) and the case of rejection/retention(France) to find out some political meanings imbedded in those cases.

An ontology is a complex structure dictionary that defines the relationship between terms and terms related to specific knowledge in a particular field. There have been attempts to construct various ontologies in Korea and abroad, but there has not been a case in which a large scale crime investigation record is constructed as an ontology and a service is implemented through the ontology. Therefore, this paper describes the process of constructing an ontology based on information extracted from instrusion theft field of unstructured data, a crime investigation document, and implementing an ontology-based search service and a crime spot recommendation service. In order to understand the performance of the search service, we have tested Top-K accuracy measurement, which is one of the accuracy measurement methods for event search, and obtained a maximum accuracy of 93.52% for the experimental data set. In addition, we have obtained a suitable clue field combination for the entire experimental data set, and we can calibrate the field location information in the database with the performance of F1-measure 76.19% Respectively.

Records in Contexts (RiC) is an international archival description standard developed by integrating and normalizing four archival description standards of the International Council of Archives (ICA). RiC has the advantage of diversifying archival description, exposing the context of records, and ensuring data interoperability between disparate systems. In this study, RiC is set up as a key tool in the design of archive systems, and logical data modeling is performed to implement the database. Because of RiC's conceptual model, RiC-CM can be used as a data reference model, and which makes it possible to develop a data model that meets user requirements. Therefore, this study intends to implement these two data models: relational data model, which is widely used as the database on legacy systems, and graphical data model, which can flexibly extend objects around the relationship between information entities.

Station transfers for smart card based railway networks refer to transfer pedestrian movements that occur at the origin and destination nodes rather than at a middle station. To calculate the optimum path for the railway network, a penalty for transfer pedestrian movement must be included in addition to the cost of within-car transit time. However, the existing link label-based path searching method is constructed so that the station transfer penalty between two links is detected. As such, station transfer penalties that appear at the origin and destination stations are not adequately reflected, limiting the effectiveness of the model. A ghost node may be introduced to expand the network, to make up for the station transfer penalty, but has a pitfall in that the link label-based path algorithm will not hold up effectively. This research proposes an optimal path search algorithm to reflect station transfer penalties without resorting to enlargement of the existing network. To achieve this, a method for applying a directline transfer penalty by comparing Ticket Gate ID and the line of the link is proposed.

This study examines the effect of national identity and threat awareness on the multi-cultural acceptability and whether contact theory actually work. For the analysis, this study used '2013 Korea General Social Survey' data and compared two groups divided according to whether or not they live in ethnic places using structural equation modeling. The empirical analysis shows that national identity does not have a direct effect on multi-cultural acceptability, and threat awareness has a full mediating effect between national identity and multi-cultural acceptability. In addition, the negative effect of the threat awareness on multi-cultural acceptability was greater in groups living in ethnic places. The findings suggest that multi-cultural awareness education is necessary to reduce the threat awareness toward foreigners, and that community-level programs are needed to prevent and coordinate conflicts arising from contact between foreigners and Koreans.

In this study, we collected data through online travel notes from January to December 2018 and analyzed the seasonal travel characteristics of individual visiting Chinese by utilizing social network analysis. The analysis showed that Seoul is a hub for Chinese travel to Korea and the main destinations for individual visiting Chinese are concentrated in Seoul, Busan, Jeju Island, Gyeongju and Gangneung, with wide differences in seasons. The research results can be used as basic data for the development of tourism courses for individual Chinese tourists to Korea, provision of tourism services and optimization of tourism facility layout. Future research can consider continuing to use network travel notes to study the tourist destination and the mode of transportation between tourist nodes, which can provide reference for the development of tourist market and the planning and design of tourist traffic.
