Purpose - Past research has not given much attention to the roles of consumers' social relationship type in the effects of justice type of service failure recovery alternatives on their satisfaction to the alternative exposed to them. Current research aimed at exploring the moderation role of consumers' social relationship central versus peripheral in the effects of justice types of service failure recovery alternatives on the recovery satisfaction, and this research also explored whether the level of satisfaction to interaction justice-focused alternative are significantly different between the two, their social relationship central and peripheral relationship. Research design, data, and methodology - 2(social relationship central versus peripheral) between-subjects design was employed. 50 participants for each experimental group there were. Participants of each group took forceful steps in choosing one between the procedural justice-focused alternative and the distribution justice-focused alternative. χ²-analysis was used to verify that the number of choosing each alternative becomes different between the two experimental groups, and a one way ANOVA was used to verify that the extent to which participants are satisfied to the alternative chosen by them becomes different between the two groups. Results - The number of participants choosing procedural justice-focused alternative at the group of social relationship central was larger than that at the group of social relationship peripheral, whereas the number of participants choosing distribution justice-focused alternative at the group of social relationship peripheral was larger than that at the group of social relationship central. And the level of satisfaction to procedural justice-focused alternative at the group of social relationship central was higher than that at the group of social relationship peripheral, whereas the level of satisfaction to distribution justice-focused alternative at the group of social relationship peripheral was higher than that at the group of social relationship central. In addition, the level of satisfaction to interaction justice-focused alternative was not significantly different between the two groups. Conclusions - Marketers should give attention to the type of justice when developing alternatives by which consumers' service failure can be recovered. They should suggest procedural justice-focused alternative to consumers under social relationship central, whereas they should develop distribution justice-focused alternative for consumers under social relationship peripheral. And in the process of recovering service failure they also should focus on interaction justice.

Purpose - Previous research has shown that a very high level and a very low level of job scope can both be more stressful than intermediate levels of job scope. This study investigates the potential positive and negative effects of the number of accounts handled by sales personnel. The primary objective of this paper is to examine how the number of accounts salespeople handle affects their stress and performance. Research design, data, and methodology - This research conducted the data collection using a survey of salespeople in the pharmaceutical industry. I sent the survey to 420 salespeople, and received 318 usable responses. To assess measurement reliability and validity, I ran an exploratory and confirmatory factor analysis. I also employed structural equation modeling (SEM) to test all hypothesized effects in AMOS and also measured the interaction variable using Ping's (1996) approach. Results - These results show that there are linear and non-linear effects of the number of accounts handled by the salesperson on both role ambiguity and role conflict. First, the number of accounts handled by a salesperson is positively related to role ambiguity and role conflict. Second, the effect of the number of accounts handled on role ambiguity and role conflict decreases as the number of accounts handled by the salesperson increases. Third, as accounts increase from a low level, role stress increases; when the number of accounts reaches an optimal level, role stress decreases; and when the number of accounts increases to a high level, it can be detrimental to the salesperson's role stress. Fourth, while product complexity is positively related to role ambiguity, brand strength is negatively related to both role ambiguity and role conflict. Fifth, the greater the brand strength, the weaker the relationship will be between the number of accounts handled and salesperson role ambiguity. Finally, role ambiguity is positively related to salesperson performance. Conclusion - Too much and too little accounts increase the role ambiguity and role conflict of salespersons. Managers should identify the complex effect of the number of accounts handled by salespeople. Also, when products are complex, managers should provide training to eliminate any complex processes and complex information. These results suggest ways to decrease salespersons' role stress by ensuring an optimal level of the number of accounts and brand strength.

The objective of this research is to provide the basic material for effective hospice care by analyzing the recognition of families who have terminally ill patients over death. To do so, this research is designed to investigate the general tendency toward death and changes after hospice care. To analyse the initial status of the recognition about the death, questionnaires were provided to the families of the terminally ill patients who were taken hospice care from June 1st, 2005 to September 10th, 2005 at Saemmul Hospice. The same questionnaires were distributed to research some changes of the recognition of the death after 3 weeks. As the Data Analysis Methodology, SPSS v.10.0 statistics program were utilized. The summary of this research is as follows. First, by gender, it is analyzed that women have more fear than men in terms of incompetence sense after death. By religion, Christians have less fear than other religious people in terms of fear toward after death and general sense of death. Second, those who experienced deaths of close family members, relatives, friends for the past 3 years have more fear toward the moment of death than those who did not experience it. Third, statistically valid difference was found in terms of fear toward the moment of death, fear toward incompetence, fear toward after death, and fear toward death before and after the hospice care was taken. Based on the result of this research, terminally ill patients' families facing death have shown significant differences on fear and incompetence before and after hospice care was offered. It is necessary that the hospice care should be settled more professionally by expanding the opportunities of hospice care and institutionalizing the system. In addition, hospice activities which are focused on providing hope after death and facing death with dignity and peace should be expanded increasingly as the family members who experienced deaths showed higher degree of fear and powerlessness and Christians have less fear toward death with the help of biblical influence. It is also required that hospice care specialized in recognizing the importance of terminal cancer patients and their families at the same time.
