The purpose of this study was to apply the k-prototypes algorithm, capable of handling both continuous and categorical variables, to gain insights into the changes in travel patterns between the pre- and peri-COVID-19 pandemic periods. For the empirical analysis, data from the National Travel Survey conducted from 2018 to 2021 were extracted, specifically focusing on respondents in Seoul, Gyeonggi, and Incheon (n=21,161). A comparison between the pre- and peri-COVID-19 pandemic periods revealed significant changes, including an increase in visits to short-distance destinations, a decrease in the number of travel companions and travel spending, an increased reliance on personal experiences as a source of travel information, and a decrease in travel among the elderly population. Furthermore, a comparative analysis of travel pattern clusters demonstrated that six travel pattern clusters, namely ‘long-distance travel group’, ‘high-frequency travel group’, ‘friend/couple group’, ‘travel group with children’, ‘high-spending group’, and ‘group traveler’, remained consistent during the peri-COVID-19 period, except for the ‘group traveler’ cluster. The implications of the research findings are discussed, along with suggestions for future research directions. 이 연구는 범주형 자료와 수치형 자료를 동시에 고려하여 분석할 수 있는 K-prototypes 알고리즘을 적용하여코로나19 팬데믹 선언 전후의 국내 여행행태를 비교하기 위해 수행되었다. 실증분석을 위해 2018년부터 2021년까지의문화체육관광부 ‘국민여행조사’ 자료(n=21,161)를 이용하였다. 코로나19 팬데믹 선언 전후의 비교 결과, 근거리 방문증가 및 동반자 수와 여행 경비 지출의 감소가 확인되었다. 아울러 자신의 경험에 의존한 여행 빈도가 증가하였으며, 고령자의 여행 비중이 감소하는 변화를 파악할 수 있다. K-prototypes 알고리즘을 적용한 군집 분석 결과, 팬데믹 선언이전의 여행행태 군집은 ‘장거리 여행 집단’, ‘국내 여행 빈도가 높은 집단’, ‘친구/연인 여행 집단’, ‘어린이 동반 여행집단’, ‘고지출 여행 집단’과 ‘단체 관광 집단’의 6개 군집으로 분류되었다. 팬데믹 선언 이후의 여행행태 군집에서 나타난변화는 ‘단체 관광 집단’이 나타나지 않는 것이며, 이는 거리두기 정책의 직접적인 결과로 이해할 수 있다. 반면 나머지5개 집단의 경우는 팬데믹 선언 이전의 집단의 특성을 유지하는 것으로 나타났다. 연구 결과가 갖는 시사점과 향 후연구방향에 대한 논의를 제시하였다.

Purpose This study was conducted to identify the multidimensional role of institutional mechanisms in the linear relationship of satisfaction, trust and repurchase intention, which are used as an important concept in the research of e-commerce. To this end, a research model was proposed by combining concepts which are the concept of perceived effectiveness of institutional mechanisms for overall e-commerce environment(e.g., PEEIM) and the concep of perceived effectiveness of institutional structures(e.g., PEIS) of a specific marketplace based on the social cognitive theory. Design/methodology/approach This study was conducted by dividing the data into two groups to identify institutional mechanisms and trust-building relationships according to the institutional contexts inherent in e-commerce. The institutional contexts were set up for the top two online companies and the bottom two online companies according to the results of the open market brand assessment from 2018 to 2019 in South Korea. Findings The result of this study found that PEIS had a direct impact on trust in both high and low groups respectively whereas PEEIM presented different paradoxical results in high and low groups. In the relationship between the satisfaction and the trust in the vendor of the high group, PEEIM showed negative moderating effects but in the relationship between the trust and the repurchase intention of the low group PEEIM showed positive moderating effects.

Background: The purpose of this study was to analyze the association between areas of Korea Train Express (KTX) region and external medical service use in Korean society using spatial statistical model. Methods: The data which was used in this study was extracted from 2011 regional health care utilization statistics and health insurance key statistics from National Health Insurance Corporation. A total spatial units of 229 districts (si-gun-gu) were included in this study and spatial area was all parts of the country excepted Jeju, Ulleungdo island. We conducted Kruskal-Wallis test, correlation, Moran`s I and hot-spot analysis. And after, ordinary linear regression, spatial lag, spatial error analysis was performed in order to find factors which were associated with external medical service use. The data was processed by SAS ver. 9.1 and Geoda095i (windows). Results: Moran`s I of health insurance patients` external medical service use was 0.644. Also, population density, Seoul region, doctor factors positively associated with health insurance patients` external medical service. In contrast, average age, health care organization per 100 thousand were negatively associated with health insurance patients` external medical service use. Conclusion: The finding of this study suggested that health insurance patient`s external medical service use correlated for seoul region in korea. The study results imply the need for more attention medical needs in the region (si-gun-gu unit) for health insurance patients of seoul region. It is important to adapt strategy to activation of primary health care as well as enhancing public health institution for prevent leakage of patients to other areas.

  The research designed the alert system of the asthmatic using PCS network. This system consists of mobile, gas sensor, server, base station. We can expect the prospective result as stated below.<BR>  1. The asthmatic will be able to meet the emergence by receiving the information about the pollution degree of the area that they are currently staying.<BR>  2. The asthmatic will be able to choose not to go or go with preparation in advance by receiving the degree of air pollution of the area that he or she is moving to.<BR>  3. The Public Health Center which has responsibility of the citizen"s health can provides the 24 hours of medical services with low price to the asthmatic.<BR>  4. The asthmatic can prevent to change for the worse of the asthma by receiving the messages in advance so it can reduce the medical expenses.<BR>  5. The Government can eliminate the cause of the air pollution by recognizing the degree of air pollution.<BR>  6. In case, if the degree of contamination exceeds above the standards, this system will broadcast to not only the asthmatic but also the residents so they are able to act against the air pollution.

Objectives: The purpose of this study was to analysis the health behaviors differences of adolescents depending on whether parenting behavior perceived by adolescents. Methods: The data which is used in this study was extracted from the 2011 second korean adolescents’ penal data collected by the National Youth Policy Institute. Multivariate logistic regression analysis was performed in order to find how degree parents relationship factors are associated with adolescents’ health behavior after adjusting sex, smoking(alcohol drinking) friends, and other significant variables. The data was processed by SAS 9.1. Results: Respondent’s general characteristics such as smoking(alcohol drinking)friends, parents’ job were positively relative to smoking and alcohol drinking experience. Also Parents’s affection and experience of being abused from parents were significantly associated with smoking(alcohol drinking) experience. Conclusions: Negative vertical attitude for children is important for the health risk behaviors of adolescents. To increase effectiveness of the health policy for the adolescents in korea, it is important to adapt new strategy to include the positive empowerment of adolescents’ social networks except for smoking(alcohol drinking)friends and policy support to turn negative vertical attitude for children into positive attitude for children.
