This study investigates the influence of individual blockholder on accounting quality. Prior studies investigating Korean blockholders' influence focus on the influence of controlling shareholders or institutional investors; however, they rarely examine individual blockholders' influence. This paper investigates how individual blockholders in Korean stock markets affect accounting quality of firms listed in Korean Stock Exchange. I analyze individual blockholders' influence on proxies of accounting quality using multivariate regression with hand-collected individual blockholder data. Korean law requires public firms to disclose the list of shareholders having no less than 5% of ownership. From the list of blockholders, individuals who have no explicit personal relation with controlling shareholders were classified as individual blockholders. My empirical results show that firms having individual blockholder(s) use more income-decreasing accruals than those having no individual blockholder. Furthermore, accounting information of firms having individual blockholders(s) is more conservative than that of firms having no individual blockholders. However, the presence of individual blockholder increases the tendency of loss avoidance and earnings management using overproduction and reduction of discretionary expenditure. This paper contributes to the literature by presenting the first evidence of the monitoring role of an individual blockholder on financial reporting of firms listed in the Korean stock markets.

This study examined the effect of parents' neglect behavior and children's irrational beliefs on children's anger expression style. The participants were 379 5th and 6th grade elementary school children. The major findings were as follows. Children tended to perceive higher levels of their parents' cognitive and emotional neglect than physical and home environmental neglect. Boys perceived higher levels of their parents' physical, supervisory and home environmental neglect than girls, and girls showed higher level of excessively self-expecting belief than boys. There were statistically significant correlations between the parents' neglect behavior, their child's irrational beliefs and anger expression style. A regression analysis showed that parents' physical and cognitive neglect were predictors of children's anger control. Children's excessive apprehension and avoidance beliefs were the best predictors of children's anger-in, while children's deterministic belief was the best predictor of children's anger-out. Parents' physical neglect behavior appeared to be powerful predictor.

Based on an online experiment, this research examined how uncivil expressions made by participants from the same political partisan group (in-group) influenced the emotional and behavioral intentions of other in-group members, especially when the incivility was supported by social recommendations such as "recommendations." As predicted, results showed that a higher level of vicarious shame was felt when participants perceived higher levels of incivility. However, no significant effects of social recommendations were found regarding levels of vicarious shame. That is, the level of shame was not significantly different between participants who were exposed to an in-group uncivil comment that received recommendations and participants who were exposed to in-group uncivil comment without recommendations. Findings further found two types of coping strategies -situation-reparation and situation-avoidance - among participants exposed to in-group uncivil comments. Yet no significant effects were found regarding coping strategies in response to the presence of social recommendations. Participants' feelings of shame were positively correlated with both types of coping strategies, supporting findings of previous studies. Implications of this study are further discussed.

Objectives: The aim of this study was to identify the associations with social support, stress coping strategy and depression among some urban middle-aged men and women. Methods: Considering the regional distribution 4 districts of Seoul were conveniently selected for this study and a total of 329 middle-aged men and women participated in the self-administered survey. The survey questionaries included social support, stress coping strategy, depression and general characteristics. Results: Avoidance and problem solving strategies were significant independent variables to the men's depression scores, but social support was not significant. However middle aged female's social support more explained the variance of the depression scores than the problem solving strategy. Conclusions: Significant sociopsychological factors that affected middle-aged depression were different by sex and according to the results, stress coping strategy for men and social support for woman were significant factors on depression control in urban middle-aged population.

Psycho-educational interventions are not a substitute for analgesics, but they may serve as adjuvant therapy. Nurses can provide psychoeducational programmes to cancer patients to assist them in optimizing behavior that strengthen adjustment. The aim here was to determine the effects of psychoeducation on levels of adjustment to cancer in stage I-II breast cancer patients who met the study criteria (experimental group: 38 women, control group:38 women). The psychoeducational program consisted of eight 90 minute weekly sessions and data were collected using a questionnaire and the Mental Adjustment to Cancer Scale three times: before, six weeks and six months after the intervention. Data analysis was performed using descriptive statistical methods as well as the Chi square test, the Mann Whitney U test, repeated measures analysis of variance, the matched pairs t test and the Post Hoc Bonferroni test. The results at 6 weeks and 6 months after the program revealed that the experimental group had higher levels of "fighting spirit", lower levels of "helplessness/hopelessness, anxious preoccupation and fatalism" but there was no significant change in levels of "avoidance/denial" compared to the control group with regard to adjustment to cancer. In this study, psychoeducation was shown to cause positive changes in levels of adjustment to cancer in breast cancer patients

Though the functions and operational procedures of current ACAS-II are upgraded several times owing to technical advancement, so far the mid-air collision accidents never come to an end. Recently to solve the major issues of ACAS-II, ICAO began to develop a future ACAS (Airborne Collision Avoidance System) by the year 2015. Accordingly in order to prepare for international standardization of the future ACAS, in this paper a policy is proposed for domestic implementation of the future ACAS based on the results from studying the technical standards and future development trends of ACAS.

Stall inception in a high-speed centrifugal compressor has been examined. The main objective was to find stall precursor and to develop a reliable stall warning method. For stall warning, a method which uses the spectrum at impeller frequency is suggested. The use of the spectrum at impeller frequency as a stall warning method showed a warning time of about two hundreds impeller revolutions. This method uses only one sensor that it has made the stall warning method more useful. And the well-known traveling wave energy method proved to be a good method for stall warning also in a high-speed centrifugal compressor. The warning time was about one hundred impeller revolutions at lower speeds, and about one thousand impeller revolutions at higher speeds. The stall warning methods used here were found to be robust and reliable. Therefore, it seems to be promising to set up a reliable stall avoidance control based on this analysis.

There have been a lot of approaches to evaluate and predict transmission control protocol (TCP) performance in a numerical way. Especially, under the recent advance in wireless transmission technology, the issue of TCP performance over wireless links has come to surface. It is because TCP responds to all packet losses by invoking congestion control and avoidance algorithms, resulting in degraded end-to-end performance in wireless and lossy systems. By several previous works, although it has been already proved that overall TCP performance is largely dependent on its loss recovery performance, there have been few works to try to analyze TCP loss recovery performance with thoroughness. In this paper, therefore, we focus on analyzing TCP's loss recovery performance and have developed a simple model that facilitates to capture the TCP sender's behaviors during loss recovery period. Based on the developed model, we can derive the conditions that packet losses may be recovered without retransmission timeout (RTO). Especially, we have found that TCP Reno can retransmit three packet losses by fast retransmits in a specific situation. In addition, we have proved that successive three packet losses and more than four packet losses in a window always invoke RTO easily, which is not considered or approximated in the previous works. Through probabilistic works with the conditions derived, the loss recovery performance of TCP Reno can be quantified in terms of the number of packet losses in a window.
