This research empirically examined changes in the images of Korea over three points in time among Japanese, Chinese, and U.S. visitors to South Korea. Between March 14 and May 31, 2005, about two to three months after the 2005 Seoul International Sports & Leisure Industry Show ended, 153 tourists from America, 129 from China, and 156 from the Japan completed the survey instrument. The results from a General Linear Model (GLM) with repeated measures showed that tourists from all three countries had more positive images after the Seoul International Sports & Leisure Industry Show than before it. It was concluded that the 2005 Seoul International Sports & Leisure Industry Show appeared to have a significant positive effect in enhancing the image of South Korea. The study suggests that an internationally significant trade Show can change the image of a tourism destination in a short time period.

Recently, digital contents systems have been constructed by means of a Web-based Information Systems(WBIS). However, developers supper from the Web Crisis since there is no systematic methodology for development and maintenance of the WBIS. To partially cope with the problem, we propose web-based business process and navigation modeling methods for efficient restructuring of a WBIS. A Business Process Net model is the business process model. Additionally, system structure model, state transition model, and user interaction model are the navigation models. These models might be useful for development and restructuring of a WBIS which includes digital contents.

지하철 역사의 미세먼지 절감을 위한 ICT 기반의 연구들이 활발히 수행되고 있다. 본 연구에서는 디지털 트윈 기반 통합 공기질 모니터링 및 분석 시스템을 소개한다. 이 시스템은 (1) 지하철 역사에 설치된 다양한 IoT 센서로부터 데이터들을 수집하여 엣지 디바이스를 통해 디지털 트윈에 전달하고, (2)실제와 동일한 실감형 3D 디지털 트윈을 통해 현재의 상황을 모니터링하며, (3) AI와 CFD 시뮬레이션 기술을 통해 공기질의 예측을 수행하여 최적의 공기질 상황으로 역사를 유지할 수 있도록 돕는다. 이 시스템을 강남역에 적용하여 결과를 분석했다. ICT-based studies are being actively conducted to reduce fine dust in subway stations. In this study, an integrated air quality monitoring and analysis system based on a digital twin was introduced. This system provided the following functionalities: (1) collected data from various IoT sensors installed in subway stations, and delivered it to the digital twin through edge devices; (2) monitored the current situation through realistic 3D digital twin, and (3) helped to maintain the optimal air quality of subway stations through air quality prediction, using AI and CFD simulation technology. Results were analyzed by applying the system to Gangnam station.

The objective of this study was to explain the impact of supervisor``s mentoring on the newcomer’s adjustment to Organizations. To improve the effectiveness of human resource management of the airlines, a relationship between supervisor (mentor) and new employees (mentees) was underpinned by theoretical background and practical implications. The study is based on 250 new flight attendants of major airlines and Low cost carriers in korea, and used the AMOS 7.0. Findings of the study are as follow. Amongst mentoring functions, a career development function and a psycho-social function indicated higher career job satisfaction and organizational commitment than a modeling function showing lower job satisfaction and organizational commitment.
