  • There is a serious unfairness problem between upstream and downstream flows of AP in IEEE 802.11 Wireless LAN. This problem is because Wireless LAN's DCF MAC protocol provides AP with equal channel access priority to mobile noded. Also, it makes this problem worse that the TCP's Data segment loss is more effective on throughput than the TCP's ACK segment. In this paper, we first make several simulations to analysis the unfairness in the various point of view and to find reasons of the unfairness. Also, this paper presents AP's scheduling scheme to alleviate the unfairness problem and evaluate the scheme through ns2 simulator.

  • The purpose of this study was to explore the unfairness of adhesion contracts for internet contents service. The internet contents were classified into six types of avatar, learning, download, e-book and movie internet sites. The adhesion contracts of internet contents service were collected in 60 internet sites. The unfairness of the adhesion contract was reviewed under the adhesion contract regulation act. The major results were as follows. First, the obligation of clear statement, explanation, and delivery was not observed completely. Second, many articles of adhesion contract were unfair and they especially violated articles 7 and 9. Therefore, the standard adhesion contract system for internet content service should be enforced and self-regulation of information service providers is needed.

  • This paper critically examines the role performance of local distributors within the Stimulus-Organism-Response (SOR) model, while also considering the moderating influence of market competition on the organism (O) and response (R) elements. Adopting a holistic approach, the SOR model provides a comprehensive framework for analyzing how external stimuli, including distributive, procedural, and interaction unfairness, interact with internal psychological processes, such as perceived unfairness, to shape the long-term orientation of importing agents. Moreover, this study acknowledges the pivotal role of market competition in the operational context of local distributors. It posits that competitive market dynamics play a crucial role in intensifying the relationship between behavioral factors and the long-term orientation of distributors, thereby revealing contingent effects within the SOR model. Through the exploration of these dynamics, this study contributes to a comprehensive understanding of the interplay among external stimuli, internal psychological processes, and market competition within the SOR framework, advancing our knowledge in this field.

  • The methods of providing available bandwidth adaptively using feedback to maximize the utilization of network as well as the quality of service have been the focus of recent research activities for ATM(Asynchronous Transfer Mode). This study has been extended from the point-to-point connection to a point-to-multipoint environment as the number of applications requiring multicast service increases. It is known that the effectiveness of feedback based congestion control scheme diminishes as propagation delay increases. Especially for a multicast connection consisting of various paths and destinations with different performance and congestion status, the problem of unfairness due to different propagation delays may occur. The degree of such unfairness may change depending on various aspects of congestion control schemes. These has been, however, relatively little study on these problems. In this paper, we present how various aspects of control schemes-length of the interval between feedback generations, point of time to coalesce feedback cells from child paths, decreasing factor of source rate in case of congestion-affect the degree of unfairness. Simulation results show that degree of unfairness changes according to when the feedback coalescing happens. Expecially it is shown that the effect of feedback coalescing time to the degree of unfairness is more significant for the smaller feedback interval. It is also found that as the source rate decreasing factor becomes larger the average ACR(Allowed Cell Rate) at the source gets lower and the degree of unfairness grow larger.

  • The term 'Nepo-baby' refers to someone whose career benefits from family connections. Criticism of the so-called Nepo-baby issue is growing, especially among the MZ generation, who highly value fairness. In this study, we explored how fashion consumers perceive the Nepo-baby issue and its impact on fashion brands. Consumers are more likely to compare themselves to Nepo babies and may experience feelings of powerlessness, unfairness, relative deprivation, and loneliness. These perceptions can lead to negative feelings toward the brand, resulting in disappointment. Our research hypotheses were tested using SPSS 26.0 and AMOS 23.0. Fashion brands promoting Nepo babies affect consumers' self-perceptions of powerlessness, unfairness, relative deprivation, loneliness, and negative feelings. Brand disappointment was tested using a structural equation model. Using a multi-group path analysis, we investigated consumers' perceptions of the Nepo-baby issue and general brand stories. Our research results reveal the significant impact of controversial Nepo babies on negative feelings toward fashion brands and brand disappointment.

  • Objective: The main purpose of this study was to examine the relationship between marital conflict, parentification, and adolescent anxiety. Methods: The participants comprised 301 high school students from the Seoul province. They were asked to complete questionnaires that consisted of the State-Trait Anxiety Inventory, the Children's Perception of Interparental Conflict Scale, and the Filial Responsibility Scale-Youth. The data were analyzed by frequency analysis, Cronbach's ${\alpha}$, descriptive statistical analysis, Pearson's correlation coefficients, multiple regression analysis, and hierarchical multiple regression analysis. To analyze the collected data, SPSS 18.0 was used. Results: First, the content and resolution of marital conflict had an effect on both adolescent state anxiety and trait anxiety. Second, unfairness parentification had an effect on both adolescent state anxiety and trait anxiety. Third, the frequency of marital conflict had an effect on emotional parentification. Further, the intensity, content, and resolution of marital conflict had effect on unfairness parentification. Fourth, unfairness parentification played a partial mediating role in the relationship between the content of marital conflict and adolescent anxiety (state anxiety/trait anxiety). In addition, unfairness parentification played a complete mediating role in the relationship between the resolution of marital conflict and adolescent trait anxiety. Conclusion: These results indicate that parentification plays an important role in marital conflict and adolescent anxiety. In addition, this study also shows that marital conflict has an important effect on adolescent anxiety directly. Therefore, this study will be useful for developing both parental education and counseling programs for adolescents.

  • Service failure and a poor service recovery may lead loyal customers to try to aggressively punish the service firm. We use perceived betrayal and desire for vengeance as the key constructs to understand customer retaliation. Perceived betrayal is defined as a customer's belief that a firm has intentionally violated what is normative in the context of their relationship. And the desire for vengeance is defined as the retaliatory feelings that consumers feel toward a firm, such as the desire to exert harm on the firm. The perceived betrayal and the desire for vengeance are key antecedents of retaliatory behaviors such as vindictive complaining, negative WOM and third-party complaining for publicity. The empirical results suggest that betrayal is a key motivational factor that lead customers to restore fairness by making use of all means, including retaliation. We also find that relationship quality has effect on a customer's response to a failure in service recovery. As the levels of relationship increases, a violation of the proper fairness has a stronger effect on the sense of betrayal experienced by customers. Considerable research has investigated consumer responses to dissatisfaction. But our study examine the response of outraged and highly frustrated consumers. We focus on emotional and behavioral processes that have not been covered by previous dissatisfaction researches and which are unique to outraged consumers caused by extremely dissatisfied purchase experience. It has recently been pointed out by various mass media that the customers not only have positive effects on the company performance but also put the company in crisis. It has often been reported that one customer's dissatisfaction, for example, never ends as it is, and it tends to grow for retaliating upon the company, depending on the level of seriousness of the dissatisfaction. This sometimes leads to a lawsuit against the company. Our study focuses on the customers' emotional and behavioral responses induced by their extreme dissatisfactions. We divided the customer groups into the customers with high relationship quality and the customers with low relationship quality, and the difference between two groups is examined. The objective of this study is to comprehend the causal relationship between the feeling of betrayal caused by the service failure and the retaliatory behavior triggered by the desire of revenge. Our study is divided into three parts. First, a causal relationship between perceived unfairness and the perceived betrayal and desire for revenge. Second, the effect of the perceived betrayal and desire for revenge on the retaliatory behavior is investigated. Finally, the moderating role of relationship quality in the causal relationship between the unfairness in service recovery and the perceived betrayal is analyzed. This study finds the following empirical results. The distributive unfairness, procedural unfairness and interactional unfairness had significant effects on the perceived betrayal. Especially, the perceived distributive unfairness results in the highest perceived betrayal. When the service company does not provide customers proper and sufficient compensation for the failure, they feel the strong sense of betrayal. And in the causal relationship between the perceived betrayal, desire for revenge and retaliatory behavior, the perceived betrayal has significant effects on e desire for revenge. In addition desire for revenge has significant effects on negative word of mouth, retaliatory complaining behavior and publicity of complaints through third group. Therefore the perceived unfairness has effects on retaliatory behavior through the mediation of the perceived betrayal and desire for revenge. Finally the moderating role of relationship quality was examined in the relationship between the unfairness and perceived betrayal. If the customers experienced the perceived unfairness in the process of service recovery, the customers with high relationship quality feel the stronger perceived betrayal than the customers with low relationship quality do. When they experience the double service failure, the customer group with high relationship quality accumulating the sense of trust feel the more perceived betrayal than the customer with low relationship quality who do not have strong trust. The contribution of this study is to find the effect of the service failure on the retaliatory behavior with the moderating roles of relationship quality. The dimensions of unfairness in service recovery is found to have differential effects on the perceived betrayal, desire for revenge. And these differential effect is moderated by the level of relationship quality.

  • Purpose The purpose of this study is to examine whether customers' shadow work and risk perception have an impact on revisit intention to the fast-food restaurant, with mediating role of different types of attribution tendencies. We also added perceived unfairness in the research model, in order to verify its mediating effect on the relationship between attribution tendencies and revisit intention. Design/methodology/approach Applying the shadow work perspective and attribution theory, we designed a research model to confirm the hypotheses. After collecting the data from 331 customers who have used self-service technology in a fast-food restaurant, we conducted an analysis of measurement model and structural model by using Smart-PLS 3.0. Findings This study confirmed that Forced Use of self-service technology can enhance the tendency of dispositional attribution which would negatively affect perceived unfairness and revisit intention. On the other hand, affective risk perception was proven to affect situational attribution, which positively affects revisit intention.

  • Purpose: The purpose of this study is to explore college women's views of women for forming an upright sex role identity and sex values. Method: The data were collected through in-depth interviews of 10 college women on Jeju Island from February 2002 to March 2002. The interviews were conducted by the writer of this thesis. Each interview lasted for about 45 minutes. The data were analyzed by the Giorgi method. Result: Five main meanings were identified: 1) unfairness 2) majesty 3) mothering 4) womenishness 5) backward in capacity. In other words, women's roles are to look after their family and to take care of household affairs. Women should be beautiful and have womenish traits. Women are less intelligent than men. Women are dependent on men though they suffer from unfairness. This study presents an evidence that the traditional sex-role attitudes still prevail. Conclusion: In order to form an upright sex role identity and sex values, institutional programs in the society and individual efforts are needed.
