Existing buffer management schemes for shared-memory output queueing switches can be classified into two types: In the first type, some constant amount of memory space is guaranteed to each virtual queue using static queue thresholds. The static threshold method (ST) belongs to this type. On the other hand, the second type of approach tries to maximize the buffer utilization in 머 locating buffer memories. The complete sharing (CS) method is classified into this type. In the case of CS, it is very hard to protect regular traffic from mis-behaving traffic flows while in the case of ST the thresholds can not be adjusted according to varying traffic conditions. In this paper, we propose a new buffer management method called weighted dynamic thresholds (WDT) which can process packet flows based on loss priorities for quality-of-service (QoS) functionalities with fairly high memory utilization factors. We verified the performance of the proposed scheme through computer simulations.

The purpose of this study was to examine the influence of person-job fit on organizational deviance and mediating effects of job satisfaction and organizational commitment(affective commitment and continuance commitment) on this relationship. Data were collected from 533 employees who were working in social welfare organizations by questionnaires. The result indicated that there were significantly positive relationships between person-job fit and job satisfaction or organizational commitment(affective commitment and continuance commitment). Also, there were significantly positive relationships between job satisfaction and affective commitment or continuance commitment. In addition, job satisfaction and affective commitment were negatively related to organizational deviance, and job satisfaction is more strongly related to organizational deviance than affective commitment. It was found that job satisfaction partially mediated the relationship between person-job fit and organizational commitment(affective commitment and continuance commitment) and affective commitment partially mediated the relationship between job satisfaction and organizational deviance. It was found that the person-job fit indirectly impacts organizational deviance though job satisfaction and affective commitment. Based on these results, the implication of this study and future research tasks were discussed.

The purpose of the study is to analyze the influence of the accomplishing pressure of teachers and parents on academic achievement in mathematics in accordance with the differences in the degree of intrinsic motivation in mathematics. The accomplishing pressure of teachers was meaningful on the academic achievement in mathematics in the analysis including the interaction of intrinsic motivation in mathematics. The students with high degree of intrinsic motivation were influenced in a negative manner. Meanwhile the students with middle or low degree of intrinsic motivation were influenced in a positive manner. The result implies that it is more important to consider the level of mathematical intrinsic motivation, when teachers accomplish an achievement pressure to improve academic achievement in mathematics. On the analysis including the interaction of intrinsic motivation of mathematics, the accomplishing pressure of parents showed positive effect in general on the academic achievement in mathematics. The students with high or middle degree of intrinsic motivation were highly influenced in a positive manner than the students with low degree of intrinsic motivation. The result implies the necessity of the implementation of continuous accomplishing pressure on students as the high degree of accomplishing pressure of parents leads to positive influence on the academic achievement in mathematics.

For this study, we distributed a total of 480 questionnaires to those sampled through non-probability sampling from people living in small and medium cities including Seoul. Collected data were coded and entered into the computer, and statistically processed using SPSS Statistics 18 The results were as follow: First, service quality of professional sports significantly effect on licensing product intentions, but identity could not effect on licensing product intentions. Second, Identity as a moderating variable has significantly positive effect on the relationship between star player of service quality and Licensing Product Intentions. In conclusion, the companies that participate as title sponsors in professional sports were proven to promotion their licensing product intentions, as identified with sports fans through service quality of professional sports such as record, attractiveness, star player and locally affiliated.

The purpose of this study was to verify the mediating effect of adaptive/maladaptive cognitive emotion regulation strategies in the relation between perceived spouse's covert narcissism and marital satisfaction. For this purpose, 300 adults who were married in Seoul and Gyeonggi province were subjected to covert narcissism, marital satisfaction, and cognitive emotion regulation strategy scale and analyzed using the SPSS 23.0 program. The results of the study was followed. First, perceived spouse's covert narcissism showed a significant negative correlation with marital satisfaction and adaptive cognitive emotion regulation strategy, whereas it showed a significant positive correlation with maladaptive cognitive emotion regulation strategy. The marital satisfaction showed a significant positive correlation with adaptive cognitive emotion regulation strategy, but a significant negative correlation with maladaptive cognitive emotion regulation strategy. Second, adaptive/maladaptive cognitive emotion regulation strategies partially mediated the effects of perceived spouse's covert narcissism of on marital satisfaction. Based on these results, the implications and limitations of this study and suggestions for future research were discussed.

In this study, we investigated whether the model attributes of CSR ads (value addition, attractiveness, expertise, trustworthiness) affect the attitude of the company. We also examined the mediating role of message authenticity in the model attributes and corporate attitudes of CSR advertisements. The results of the study are as follows. First, the value addition, attractiveness, and reliability of the CSR advertising model have a positive effect on the message authenticity of the CSR advertisement. Second, the attractiveness and expertise of the CSR advertising model have a positive effect on the attitude of the company. Third, the effects of the CSR advertising model on the value addition, attractiveness, and reliability are completely mediated by the message authenticity of the CSR advertisement. The results of this study suggest that it is effective to select the models with value addition, attractiveness, and expert image when producing CSR advertisements.

This study analyzed parents' school satisfaction longitudinally using data from the 1st, 3rd, and 5th wave data of the Korea Education Longitudinal Study(KELS)2013. The subjects of analysis are parents who responded without dropping out in the first, third and fifth panel of the KELS2013, and 4,227 cases that had no missing values in the variables were selected for the sample to input for analysis of the latent growth modeling(LGM). As a result, it is confirmed that the parents' education, educational support, and children's academic achievement have a positive effect on the parents' school satisfaction. But the parents' educational view and education cost have a negative effect on that. The results of this study are expected to be important information to help enhance the primary function of the school.
