Purpose: This study aimed to present an analysis model evaluating evacuation performance considering patient types and procedural evacuation in the medical facility. The user group of the medical facility, including users challenged in evacuation behavior, entails the risk of many casualties. Therefore, it is necessary to plan an evacuation procedure that considers the evacuation characteristics of users. Methods: Through the review of precedent studies, the evacuation procedure of the medical facility, the classification of patient types, and the evacuation procedure was set as conditions and variables for the analysis. The result caused by a variety of conditions and variables were explored. Results: 1) The total evacuation completion time and congestion time were shortened at the procedural evacuation. Moreover, it derived many users from evacuating at the initial phase. 2) The proposed model can provide a basis for proposing a space planning direction that considers the possibility of not carrying out the evacuation plan. 3) It supports safe evacuation by identifying variables that reduce overcrowding by comparing the congestion time of overcrowded spaces. 4) The analysis model can identify the overcrowded space through the evacuation route and suggest the basis for architectural improvements that reduce overcrowding. Implications: The study results can be used to analyze the performance of evacuation procedures and support the establishment of evacuation procedures and building plans for safe evacuation for medical facilities.

Purpose - This research is intended to suggest ways to enhance customers' satisfaction with service recovery. For this purpose, this study investigated the relationships among perceived justice (distributive, procedural, interactional justice) of service recovery efforts, perceived authenticity of service recovery efforts, the intention to follow advice, and the satisfaction with service recovery. Research design, data, and methodology - This research developed a structural equation model in which the perceived justice (distributive, procedural, interactional justice) and the perceived authenticity are predictors, the satisfaction with service recovery is a dependent variable, and the intention to follow advice is a moderator between the perceived justice (distributive, procedural, interactional justice) and the satisfaction with service recovery. Data were collected from visitors of fast food restaurants in Seoul, Gyeonggi province, and Kangwon province. A total of 330 questionnaires were distributed and 295 responses were collected indicating a response rate of 89.3%. After deleting data having missing value, 288 samples were used for analysis. SPSS 21.0 and AMOS 21.0 were used to test the reliability, validity, model fit, and hypotheses. Results - Empirical results showed that perceived justice, perceived distributive justice, and perceived authenticity had a positive influence on the satisfaction with service recovery. These results indicated that the more highly customers perceived the justice, distributive justice and the authenticity of service recovery efforts, the more they were satisfied with service recovery. And these influences were moderated by the intention to follow advice. Specifically, influences of the perceived justice, the perceived distributive justice, and the perceived authenticity on the satisfaction with service recovery were bigger for people with high intention to follow advice than people with low intention to follow advice. Conclusions - This research contributed to the service recovery literature by showing how perceived justice (distributive, procedural, interactional justice) and perceived authenticity influence satisfaction with service recovery. Moreover, current study introduced the intention to follow advice as moderator of this influence and revealed the moderation role of the intention to follow advice between the perceived justice (distributive, procedural, interactional justice) and the satisfaction with service recovery. Managerially, these results suggested retailing companies some ways to recover from service failure.

The object of this research is to examine the factors leading to intercompany win-win by finding the antecedents and consequences that affect a supplier's fairness perception. We assume that the antecedent factors of a supplier's fairness perception are vertical coordination, cooperation support, information sharing, and legalistic plea. We assume that the consequential factors of a supplier's fairness perception are supply chain dependence and supply chain flexibility. The object industry is an electronic parts manufacturing company. We tested our model by using the SPSS 17.0 and the LISREL 8.5. For measurement validation, we verified by using a confirmatory factor analysis and a reliability analysis. For hypothesis analysis, we did a path analysis with the LISREL 8.5. By checking the modification index and expecting parameter changes, we modified the model. First, the buyer's vertical coordination had a positive effect on the supplier's distributive fairness perception and procedural fairness perception. Second, the buyer's cooperation support had no effect on the supplier's distributive fairness perception and procedural fairness perception: we suppose that the buyer's requests were burdensome, although they cooperated with the supplier. Third, the buyer's information sharing had a positive effect on distributive fairness perception but had no direct effect on procedural fairness perception. Fourth, the buyer's legalistic plea had a negative effect on the supplier's distributive fairness perception. and a negative effect on the supplier's procedural fairness perception at a 0.1 significance level. Fifth, although procedural fairness perception had no direct effect on supply chain dependence, fairness perception had an effect on supply chain dependence and supply chain flexibility both directly and indirectly.

Not much is known about the factors of North Korean refugees willingness to report crime. Based on the survey of 800 North Korean refugees living in the metropolitan area of South Korea, this study examined the theoretical factors influencing North Korean refugees' willingness of reporting crime. Focusing on the legal cynicism, procedural justice, and the behavior of law theory, this research verified that procedural justice model is most important in explaining their willingness to report crime. Variables under procedural justice model(i.e., perceived fairness of the law, confidence in the law, and perceived necessity of the law) were significant in an expected direction. On the other hand, most of the hypotheses based on social conditions derived from the five types of stratification, morphology, culture, organization, and social control presented by Donald Black (1974) showed no significant effects on the intent to report crime among North Korean refugees. Implications for research and policies were discussed based on the findings.

In this paper, we present a procedural modeling algorithms to create Korean traditional stone fence using the fractal subdivision. The main process of the algorithm is to get the next step mesh by subdividing each triangle in the previous step triangular mesh. This process is repeated recursively. Dividing each triangle into four sub-triangles after choosing a random point on each side of the triangle and moving each vertices in the normal direction with random perturbations make the bumpy appearance of stone fences. In each step we remove flat vertices which does not influence the shape of the stone. The discrete curvature determines the flatness of a vertex. New triangles whose vertices are the vertices around the removed vertex are added to make a triangular mesh.

Objective: The purpose of this research is to extract factors affecting office lighting and their relations, and then develop a framework that helps designers research and design smart lighting systems. Background: Due to the highly specialized usages of offices, the lighting system within offices also varies according to space, work, user, etc. A framework which considers these various factors and their relations is necessary for understanding and developing smart lighting systems. Method: First we extract factors affecting office lighting conditions, and select factors that can be controlled. We then analyze and develop a structure which reflects the relations among these factors from procedural perspective. Results: We divide factors affecting office lighting into physical and social factors, and then conceptualize their relations using a circular model. We then develop our framework from procedural perspective by dividing these factors into three levels, namely Subject, Action and Object. Conclusion: The developed framework organizes various factors affecting office lighting and their relations, and helps understand the procedural and structural aspects of lighting system. Application: Our framework helps designing and refining smart lighting system for complicated office spaces by helping people understanding the overall structure of office lighting.

The purpose of this study is to examine the dynamic relationships among locus of control as a individual traits, the three organizational equity factors(distributive equity, procedural equity and interactional equity), individual attitudes and behaviors(job satisfaction, organizational commitment and turnover intention). In this study, we designed research model based on extensive literature review and tested each hypothesis through empirical analysis of which single public organization was the subject. The results are as follows : locus of control negatively affect all the three equity factors. And distributive equity positively affect job satisfaction whereas both procedural equity and interactional equity positively affect organizational commitment. Also only organizational commitment not job satisfaction positively affect turnover intention. The various implications to manage organizational equity, job satisfaction and organizational commitment and the limitations of the study and directions for future research were discussed.

This study investigated three pre-service teachers' mathematical problem solving among hand-in-write-ups and final projects for each subject. All participants' activities and computer explorations were observed and video taped. If it was possible, an open-ended individual interview was performed before, during, and after each exploration. The method of data collection was observation, interviewing, field notes, students' written assignments, computer works, and audio and videotapes of pre- service teachers' mathematical problem solving activities. At the beginning of the mathematical problem solving activities, all participants did not have strong procedural and conceptual knowledge of the graph, making a model by using data, and general concept of a sine function, but they built strong procedural and conceptual knowledge and connected them appropriately through mathematical problem solving activities by using the computer technology.

Purpose - In the international shipping industry, arbitration is mainly chosen for resolving maritime disputes. This study investigates the "acceptability" of an international maritime arbitrator based on an existing theoretical model of arbitrator acceptability. Design/methodology - Using structural equation modeling techniques, this study examines a sample of senior managers who engage in the judicial affairs of their international shipping companies to verify a hypothesized model of arbitrator acceptability that covers cultural intelligence, arbitral experience, reputation, practical/legal expertise, and procedural justice as independent variables. Furthermore, the relative "perceived required time" of arbitration is tested as a moderator. Findings - Arbitrator acceptability is significantly influenced by six constructs of arbitrator characteristics: cultural intelligence, arbitral experience, reputation, practical and legal expertise, and procedural justice. Furthermore, the moderating effect of the perceived required time of arbitration is demonstrated in the relationship between arbitrator acceptability and arbitrator characteristics even though these relationships are not equally influenced. Originality/value - The originality of this study can be found in its context, that is, international maritime arbitration. Despite the potential growth of international maritime arbitration, existing studies have mainly focused on domestic arbitration. The findings of this study are expected to provide useful guidelines for nurturing international maritime arbitration in Korea.
