This study intended to examine how customers of self-service technology of airlines perceive and adopt the technology, and how such perceptions affect their willingness to use it. The findings of analysis are as follows. First of all, self-efficacy, a personal characteristics variable, has significant effects on both perceived usefulness and ease of use (H1). Second, though personal innovation which accepts new information technology more positively and challenge to use it before others has significant effect on perceived usefulness (H 2-1), it does not have significant effect on ease of use (H 2-2). Third, perceived ease of use has effect on perceived usefulness. Forth, both perceived usefulness and ease of use have positive effects on willingness to use.

This study identified the factors which affect pedestrian behavior using the tobit model with a descriptive analysis. Individual characteristics, household characteristics, zone characteristics were selected as the independent variables. Walking frequency and walking time was adopted for the variables which represent walking behavior. The results showed that the walking time models were superior than the walking frequency models. The model for education purpose had the most lowest fitness and the model for others purpose had characteristics mixed up the various purposes. Futhermore, this research found that independent variables: individual, household and zone characteristic variables affected walking activities of elderly pedestrian by purpose. The walking activity decresed when a pedestrian grew older or had a vehicle or a driver's license. The Elderly facilities promoted the walking activity of seniors. As the floor area of neighborhood and business facilities was wide, the walking activities were animated. In addition, the compacted downtown developments decreased the elderly's walking activities, so it is needed to consider those results in terms of the urban planners.

Mode choice behavior is associated with travelers' latent behavior that is an unobservable preference to travel behavior or mode characteristics. This paper specifically addresses the problem of unobservable factors, that is latent behavior, in mode choice models. Consideration of latent behavior in mode choice models reduces the errors that come from unobservable factors. In this study, the authors defined the latent variables that mean a quantitative latent behavior factors, and developed the combined RP/SP model with latent variables using the mode choice behavior survey data. The data has traveler's revealed preference of existent modes along the Han River and stated preference of new water transit on the Han River. Also, The data has travelers' latent behavior. Latent variables were defined by factor analysis using the latent behaviour data. In conclusion, it is significant that the relationship between traveler's latent behavior and mode choice behavior. In addition, the goodness-of-fit of the mode choice models with latent variables are better than the model without latent variables.

With increasing of smartphone users various smartphone studies have been carried out. The purpose of this paper is to examine the factors influencing the usage intention of smartphone healthcare application. The influencing factors found from literature reviews on Technology Acceptance Model and the diffusion of innovations theory are user interface design, self-efficacy, innovativeness, and entertainment. Survey is conducted to 220 people in Seoul metropolitan area. The survey results are analyzed regarding the difference for the intention of healthcare application in accordance with respondents' demographic and application usage characteristics. We also examine the difference among four influencing factors by users and non-users. As a result there are significant differences in self-efficacy and innovativeness. This gives some implications to application developers: the system should be easy to use and provide new and useful health contents that can attract early-adopters' attention in order to increase the number of application users.

현대 기업에서 정보시스템은 기업활동의 필수적이고 기본적인 요소로 인식되고 있으며 그 중요성은 점점 더 높아지고 있다. 정보시스템은 기업의 각 요소를 유기적으로 연결하여 기업의 목적이나 목표를 달성하기 위해 사용 되고 있다. 정보시스템의 도입이 이런 목표나 목적을 달성하고 있는지 살펴보기 위해 정보시스템의 품질과 조직 성과에 관한 많은 연구들이 이루어져 왔다. 조직행동론 분야에서 '조직내 갈등'이 조직성과에 직 간접적으로 영향을 미치는 것으로 나타나고 있다. 조직내 갈등은 '과업적 갈등'과'감정적 갈등'으로 나눌 수 있으며, 이들은 매개변수나 조절변수로서 조직 성과에 영향을 주고 있다. 하지만 정보시스템의 품질과 조직의 성과에 관계에 대한 많은 연구가 이루어진 반면 이들 관계에 있어 갈등의 역할에 대한 연구는 부족한 실정이다. 본 연구는 정보시스템의 품질과 조직원 성과관계에서 갈등의 역할에 초점을 맞춰 연구를 진행하였다. 이를 위해 근로자 300인 이상인 기업에 근무하는 사무직 근로자를 대상으로 설문 조사를 실시하고, PLS(Partial Least Square) 방법을 사용하여 분석을 실시하였다.

This study was conducted to review the literature and examine the factors related to problem behaviors among students of multicultural families in Korea. A systematic review of the literature was conducted using domestic documents retrieved through July 4, 2018 based on online searches of domestic databases (the Research Information Sharing Service, Korean Studies Information Service System and the National Diet Library). A total of 2,084 studies were searched, and 21 studies were used for analysis. The factors related to problem behaviors were related to individual factors (gender, school record, self-esteem, etc.), family factors (family type, parent support, mothers' enculturation stress, etc.) and environmental factors (friend support, teacher support, social support). The variables measured the problem behaviors among students of multicultural families were school life adjustment (10), psychological, social adjustment or maladjustment (4), and emotional problem behavior (3).

This study identifies key determinants of participation in UCC services. Incorporating insights from the flow theory, we examine the effects of psychological factors of social presence, self expression, arousal, and challenge as well as web-site characteristics variables of media easiness, contents usability, and immediateness. We have done a sample survey of internet users and collected 260 responses. Using Windows SPSS/PC 12.0 Package, we have performed statistical analyses including a correlation analysis, a factor analysis, and a multiple regression analysis. The result of the study is as follows. Psychological variables of perceived social presence, self expression, arousal, and challenge all show positive significant effect on participation in UCC service. Among web site characteristics, media easiness, which consists of a web structure that is easy-to-use, user friendliness, and personalized service, demonstrates a positive significant effect on participation in UCC services. Immediateness also has a positive significant effect. Some of the practical implications of the result are follows. We should improve user access to platforms of UCC service by opening up platforms. This will heighten perceived challenge which has the strongest influence on participation in UCC services. We need to focus on multimedia services and adjust to the cultural code of netizen who crave for visual expressions and on the spot on-line activities. Also suggested is that contributions made by participants need to be acknowledged through such provisions as profit sharing. Needs for individualized service, which is an aspect of media easiness, should also be addressed. Participants tend to value individuality while at the same time accepting broader trends. Information services need to be customized for individuals. In UCC centered internet businesses, netizen consumers are presumer. They are consumers and producers at the same time, and consumer needs should also be explored for the success of internet businesses.
