Purpose Although examining the antecedents of employees' extra-role behavior (i.e. information security participation behavior) in the information security context is significant for researchers and practitioners, most behavioral security studies have focused on employees' in-role behavior (i.e. information security policy compliance). Thus, this research addresses this gap by investigating how organizational information security climate influences information security participation behavior based on social information processing theory and Griffin and Neal's safety model. Design/methodology/approach We developed a research model by applying Griffin and Neal's safety model to the information security context and then tested our research model by conducting an online survey for employees of organizations with information security policies. Structural equation modeling (SEM) with SmartPLS 3.3.2 is used to test the corresponding hypothesis. Findings Our results show that organizational information security climate, information security knowledge, information security motivation are effective in motivating information security participation behavior. Also, we find that organizational information security climate positively influences both information security knowledge and information security motivation. Our findings emphasize the importance of organizational information security climate because it is capable of affecting employees on information security participation behavior. Our study contributes to the literature on information security by exploring the role of organizational information security climate in enhancing employees' information security participation behavior.

The purpose of this study is to identify the effects of emergency medical technicians' personal traits and job characteristics on job/social stress, job satisfaction, role conflicts, organizational commitment, and self-efficacy. The study population was emergency medical technicians who is working at the hospitals in Yeungnam province. The 200 questionnaires were administered by using ground mail, e-mail, and personal visits and 156 questionnaires were returned(82.5% response rate). Social stress, job satisfaction and role conflicts were significantly determined by personal traits and job characteristic variables. However, job stress, organizational commitment and self-efficacy was only significantly determined by job characteristic variables. In social stress and role conflicts, the subjects with challenge, sociability, acceptance and prudence traits were tend to be significantly higher scores compared to the stability traits. Additionally, among social stress regression models, adding job characteristics to the personal traits model, $R^2$ was increased up to 19% and adding personal traits to the job characteristics model, $R^2$ was increased up to 14%. In conclusion, the study found that personal traits and job characteristics are important variables in explaining social stress, job satisfaction and role conflicts, that would have important managerial implications for recruiting, hiring and managing either new or current emergency medical technicians efficiently.

In this study, we try to understand the role of online social recommendation and the similarity of preferences between the recommender and the recommendee on consumer decisions in the framework of the two stage purchase decision-making process. Applying construal level theory to our context, we expect that the role of social recommendation and the similarity of preferences would vary over the stages in the two-stage decision making process. To test our hypotheses, we collected the data through an incentive compatible experiment, and analyzed the data with nested logit model. As a result, we found that the role of online social recommendation varies over the stages. Consumers take recommendation from similar others at the stage of consideration set formation, but no longer consider it at the stage of final choice. Consumers take recommendation from dissimilar others at the stage of consideration set formation. At the stage of final choice, however, consumers avoid choosing the option recommended by dissimilar others. The results of our study enrich the understanding about the role of social recommendation, and have implication to marketing practitioners who attempt to make online social recommendation system more efficient.

Purpose - The third place plays an important role in complex society. The more customers participate in the third place, the higher they have loyalty. It is necessary to identify the mediator between customer participation and loyalty. Thus, the purpose of the study is to analyze the relationship between customer participation and loyalty and a mediating role of psychological ownership. Research design, data, and methodology - A structural equation model representing the relationships between customer participation, psychological ownership, and customer loyalty was proposed and four hypotheses were tested using data collected from visitors of Starbucks as the third place. Results - Three hypotheses regarding relationships between customer participation, psychological ownership, and customer loyalty were supported at the significance level of 0.001. The hypothesis regarding a mediating role of psychological ownership between customer participation and customer loyalty was supported by Sobel test. Conclusions - Customer participation positively affects psychological ownership and customer loyalty. Psychological ownership positively affects customer loyalty. Psychological ownership plays a mediating role in the relationship between customer ownership and loyalty. This study contributes to finding the missing link between customer participation and customer loyalty. The research model can be applied to various retail services. Some implications for academics and practitioners were suggested.

Referral marketing plays an important role in promoting new products. When it comes to innovative agricultural products, early adopter's review or recommendation has a more critical impact on follower's purchase decision making. Hence, understanding of consumer's characteristics and needs play more important role in success of innovation. More particularly, other researchers pay attention to the role of consumer innovativeness. This study attempts to fill this gap in knowledge between innovative propensity of consumer and her/his intention to generate positive word of mouth about new agricultural products. Furthermore, in this paper, we adopt Vandecasteele and Geunes' motivated consumer innovativeness model to investigate consumer innovativeness in extrinsic motive and intrinsic motive level, and examine the moderating role of referral efficacy. For empirical verification, survey method is used for data collection. Partial least square (PLS) is adopted to analyze the data. Finally, several theoretical contributions and practical implications are discussed.

Purpose - The study investigates the role of authenticity of B2B salespersons has on their consultative selling competence. The study also examines the mediating effect of customer orientation between the authenticity of B2B salespersons and their consultative selling competence, as well as the moderating role of trust in the buyer-seller exchange. Design/methodology/approach - This research utilized a covariance-based structural equation model technique. The study assessed the research model's moderation effects through a stepwise approach, which allowed for an examination of the moderating effect of trust in the buyer-seller relationship. Findings - As a result of structural equation analysis, this study found that the authenticity of B2B salespersons influences their consultative selling competence by mediating their customer orientation significantly. In addition, trust in the buyer-seller exchange plays a significant role as a moderating variable between customer orientation and competitive selling competence, but it is not significant as a moderating variable between the authenticity and customer orientation of B2B salespersons. Research implications or Originality - This research proposed the role of authenticity of the B2B salesperson as a key factor in the trust-based relationship and a key variable of consultative selling competence. The study has taken the research on the authenticity of the B2B salesperson one step further from the study of authenticity of the brand and the company's leadership.

This qualitative research provides a situation model, which is designed for promoting learning of eigenvalue and eigenvector. This study also demonstrates the usefulness of the model through a small groups discussion. Particularly, participants of the discussion were asked to decide the numbers of milk cows in order to make constant amounts of cheese production. Through such discussions, subjects understood the notion of eigenvalue and eigenvector. This study has following implications. First of all, the present research finds significance of situation model. A situation model is useful to promote learning of mathematical notions. Subjects learn the notion of eigenvalue and eigenvector through the situation model without difficulty. In addition, this research demonstrates potentials of small groups discussion. Learners participate in discussion more actively under small group debates. Such active interaction is necessary for situation model. Moreover, this study emphasizes the role of teachers by showing that patience and encouragement of teachers promote students' feeling of achievement. The role of teachers are also important in conveying a meaning of eigenvalue and eigenvector. Therefore, this study concludes that experience of learning the notion of eigenvalue and eigenvector thorough situation model is important for teachers in future.

본 연구에서는 과학의 본성을 현대적 관점으로 변화시킬 수 있는 프로그램으로서 2 종류의 과학사-역할놀이 프로그램을 고안하여 그 프로그램의 적용 효과와 과학사 주제별 과학의 본성의 인식의 변화에서 차이가 있는 지를 알아보았다. 과학사 주제에 따른 역할놀이 활동 전후의 과학의 본성 인식변화 효과의 차이를 분석한 결과 I 그룹(원자모형의 변천-역할놀이 활동)과 II 그룹(멘델레프 주기율 표-역할놀이 활동)을 수행한 그룹 사이에 과학의 본성 인식 정도가 통계적으로 차이가 없는 동질한 그룹이었으나, 각각의 주제로 과학사-역할놀이 처치를 한 후 시행한 사후검사에서 I 그룹이 II 그룹보다 그 인식의 정도가 통계적으로 유의미한 차이로 높게 나타났다. 이는 과학사-역할놀이 활동을 처치한 후에 과학의 본성에 대한 인식의 변화 정도는 각각의 역할놀이와 결합시키는 과학사의 주제에 따라 그 효과가 차이가 있을 수 있음을 의미하는 것이다. 본 연구결과는 주제의 흥미도와 난이도를 고려하기 보다는 시계열적 과정을 거쳐 다수의 과학자들이 과학적 이론을 정립해 가는 과정이 포함된 과학사 주제를 선택하여 과학사-역할놀이 활동을 할 경우 과학의 본성의 변화에 더 효과적일 수 있다는 가능성을 시사한다.

역할기반 접근제어(RBAC)는 역할(Role)과 역할계층(Role hierarchy)을 통해 사용자 및 접근권한 관리를 효율적으로 수행할 수 있도록 해준다. 그러나 시스템에 수많은 사용자, 역할, 권한이 존재하는 경우 한사람의 보안 관리자가 이들을 모두 관리하는 컷은 불가능하므로 역할을 관리하는 관리역할을 두어 시스템을 효율적으로 관리할 수 있는 방법(ARBAC)이 제안되었다. ARBAC는 URA(User Role Assignment), PRA(Permission Role Assignment), RRA(Role Role Assignment)로 구성되어있다. 본 논문에서는 URA99 모델을 기반으로 사용자-역할 관리를 위하여 관리도구를 구현한다. 구현된 관리도구는 오라클의 저장 프로시저를 사용하고 자바를 기반으로 한 EJB 컴포넌트로 구현한다.
