Hotel consumers tend to rely on online reviews to reduce the risk to hotel products when they book hotel rooms because hotel products are high-risk products due to their intangibility. However, the development of ICT has caused information load, and it is an important issue to be perceived as useful information to consumer because a large amount of information complicates the decision making process of consumers. Drawn from Heuristic-Systematic Model(HSM), the present study explored the role of heuristic and systematic cues composing an online review influencing consumers' perception of hotel online reviews. More specifically, this study identified reviewers' identity, level of the reviewer, review star ratings, and attached hotel photo as heuristic cue, while review length, cognitive level of review and negativity in review as systematic cues. The binary logistic regression was adopted for analysis. This study found that only systematic cues of online review were found to affect the usefulness of it. Moreover, we preceded further study examining the moderating effect of seasonality in the relationships between systematic cues and usefulness.

As the growth of online travel agencies (hereafter OTAs) accelerates, competition among hotels to gain exposure on the first page of OTA websites, and the financial burden, such as commissions hotels have to pay in return, are increasing. Therefore, to facilitate successful management in the tourism industry, it is important to establish what makes people continue the practice of using OTAs to book rooms in hotels and other accommodation outlets. By adopting the heuristic-systematic model (HSM), this study explores the factors that drive consumers' continued use of OTA and classifies them into heuristic cues (brand awareness, cost saving, and scarcity message) and systematic cues (recommendation quality and the ability to provide reputation). Furthermore, we divided the sample based on the location of hotels within and outside Korea, and investigated the different roles of the cues between two models. The results are expected to provide theoretical and practical implications for both OTAs and hotels.

Purpose Along with the growth of smart phones and social networking service (SNS), social commerce continues to expand. Although online reviews have become an important source of the information that consumers use to make purchasing decisions, theoretical development and empirical testing in this area are still limited. Thus, there is a need to develop further understanding about the influence of electronic word-of-mouth (eWOM). Drawing upon the heuristic - systematic model (HSM) which is one of the dual-process theories, this study develops a research model that explains key factors influencing consumers' eWOM credibility. Furthermore, this study verifies that consumer's eWOM credibility is a key determinant of eWOM and purchase intentions. Design/methodology/approach The proposed model is empirically tested with 493 users who have experience in WeChat-based social commerce. The structural equation model (SEM) analysis is used to evaluate the research model and hypotheses. Findings The major findings are as follows. First, argument quality of eWOM (a systematic factor) has a positive effect on eWOM credibility. Second, source credibility and recommendation consistency of eWOM (heuristic factors) are positively associated with eWOM credibility. Finally, purchase and eWOM intentions greatly depend on eWOM credibility. These results confirm the effectiveness of HSM in explaining eWOM mechanisms in SNS-based social commerce. The details of findings and implications are presented.

Recently, with the advance of the wireless Internet access via mobile devices, a myriad of game development companies have forayed into the mobile game market, leading to intense competition. To survive in this fierce competition, mobile game developers often try to get a grasp of the rapidly changing needs of their customers by operating their own official communities where game users freely leave their requests, suggestions, and ideas relevant to focal games. Based on the heuristic-systematic model (HSM) and the data quality (DQ) framework, this study derives key content, non-content, and hybrid cues that can be utilized when game developers accept suggested postings in these online communities. The results of hierarchical multiple regression analysis show that relevancy, timeliness, amount of writing, and the number of comments are positively associated with mobile game developers' knowledge adoption. In addition, title attractiveness mitigates the relationship between amount of writing/the number of comments and knowledge adoption.

A vulnerability assessment is essential for the efficient operation of a physical protection system (PPS). Previous assessment codes have used a simple model called an adversary sequence diagram. In this study, the use of a two-dimensional (2D) map of a facility as a model for a PPS is suggested as an alternative approach. The analysis of a 2D model, however, consumes a lot of time. Accordingly, a generalized heuristic algorithm has been applied to address this issue. The proposed assessment method was implemented to a computer code; Systematic Analysis of physical Protection Effectiveness (SAPE). This code was applied to a variety of facilities and evaluated for feasibility by applying it to various facilities. To help upgrade a PPS, a sensitivity analysis of all protection elements along a chosen path is proposed. SAPE will help to accurately and intuitively assess a PPS.

Purpose - Due to the Covic-19 pandemic, the perceived value of video conferencing platforms has been increased drastically. However, there is little guidance on how service providers can improve video conferencing platforms. The purpose of this study is to investigate the factors that influence the users' perceived value of video conferencing services based on the heuristic-systematic model and the value-based adoption model. Design/Methodology/Approach - In this paper, we theoretically explore the relationship of the antecedents of perceived value(credibility, expertise, attractiveness, economic feasibility, security, and interactivity) and its outcomes (perceived usefulness, perceived risk and perceived value). The outcomes of this research is a conceptualization of antecedents of perceived value supported by research hypothesis based on the existing literature. A total of 100 valid questionnaires were collected to empirically test the research model. Findings - The analysis results showed that credibility, economic feasibility, and interactivity positively influenced perceived usefulness. On the other hand, credibility, professionalism and interactivity negatively influenced perceived risk. Perceived usefulness positively affects perceived value and perceived risk has a negative effect on perceived value. The brand image as a moderating variable was found to decrease the effect of perceived risk on perceived value. Research Implications - The contribution of this study is significant for video conferencing providers as follows. First, a service provider can actively utilize influencers or referees with high credibility and expertise to maximize the perceived usefulness of users. Second, economic feasibility should be ensured in respect of users through various alliance discount strategies. Third, a video conferencing service company needs to build a positive brand image in order to increase users' perceived value.

This study investigates the impact of heuristic factors on customers' perception of information credibility of influencers on YouTube channels, and the association between customers' perception of information credibility and brand attitude, brand credibility, and purchase intention of cosmetic products in Vietnam. A quantitative approach is employed, with a survey of 270 females who are frequent viewers of beauty content on YouTube channels. The data reliability and validity go through various statistical tests including exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Also, structural equation modeling (SEM) is applied to test the hypotheses. The results reveal that there is a positive association between heuristic factors and the perception of information credibility. This perception of information credibility also influences positively on customers' attitudes toward the brand and brand credibility. Purchase intention is also found to be positively associated with the two latter variables. The study's main findings not only offer advice to practitioners on how to choose the right product endorsers and advertising platforms, but they also offer novel insight from the Vietnamese context that could help to extend the heuristic-systematic model and customers' buy intention behavior.

버스 대중교통은 정해진 노선, 운행시간표에 의해 정류장을 경유하여 운행하므로 버스 노선망 설계 문제(BTRNDP: Bus Transit Route Network Design Problem)는 승용차위주의 가로망 설계 문제와 다른 접근방법이 요구된다. 버스 노선망 설계 문제의 적용모형은 설계방법의 역사적발전과정에 따라 매뉴얼 및 지침, 시장분석기법, 시스템해석모형, 휴리스틱모형, 하이브리드모형, 경험기반모형, 시뮬레이션모형, 수리최적화모형 등 크게 8가지 분류할 수 있다. BTRNDP는 이용자비용과 운영자비용의 조합인 총비용을 최소화하는 목적함수를 획득하기 위한 일련의 현실적 제약조건하에서 버스노선집합과 배차횟수를 결정하는 문제이다. BTRNDP는 조합최적화문제로 일반적 수리최적화문제로 가능해 공간을 정의하는 것이 어렵기 때문에 모든 가능해로 구성된 큰 탐색공간으로부터 최적해를 탐색해야하는 NP-Hard라는 특성을 가진다. BTRNDP의 목적함수는 이용자와 운영자관점을 모두 고려한 다목적함수(Multi-Objective Function)를 이용하며 수요는 고정수요를 이용하였으나 최근에는 가변수요를 고려한 방법론이 연구되고 있다. 해알고리즘으로 최적 버스 노선망을 구성하게 될 모든 가능한 후보노선집합(Candidate Route Set)을 생성하고 노선집합의 최적조합을 찾는 메타휴리스틱(Meta-heuristic) 알고리즘을 이용하여 전역최적 노선집합을 찾는 방법이 적용되고 있다. 최적 버스 노선망의 배차횟수를 결정하기 위해서 대중교통 통행배분모형이 필요한데 BTRNDP에 적용되는 통행배분모형은 다중경로 통행배분모형이 주로 활용되었다. 국내외 BTRNDP를 고찰한 결과 주요 시사점으로는 BTRNDP에서 가장 중요한 고려사항은 세분화된 버스정류장 기반 기종점통행량 구축, 버스 노선망 평가 모형 및 대중교통 통행 배분모형의 개발, 탐색 해알고리즘의 개발 등의 향후 연구내용이 포함될 수 있다.
