Most of the urban transit operation company in Korea have a passive surveillance system to monitor the status of the passengers and facilities in the urban transit service area. The surveillance system is based on CCTV, closed circuit television, and several sensors, such as a fire sensor. However, this system has some limitations to prevent and cope with the emergency quickly. So the urban transit operation companies have plans to be change their surveillance system to be active. The active surveillance system has an intelligent function to detect the event predefined by managers automatically. To construct the active surveillance system, there are a standard concept design and a function analysis. In this paper, we propose the classification of the functions of the active surveillance system for urban transit. We divide the functions into five parts, ordinary monitoring, safety monitoring, environment monitoring, administration support, and record management. And we describe the systems related to the every functions to clarify the classified functions.

The purpose of this qualitative research is to explore the intergenerational ambivalence of mothers with preschoolers. Twenty full-time mothers and 19 working mothers were interviewed in depth. Most of the participants who received instrumental support from their mothers showed ambivalence, and especially the working mothers were more likely to feel ambivalence than the full-time mothers. However, participants who received little or no support from their mothers did not report any ambivalent feelings. Their ambivalent feelings came from both their social structure and intrapersonal contradictions. In order to avoid ambivalent feelings, some participants redefined receiving support from their mothers as a positive thing. Meanwhile, the participants who received active support tried to divert their ambivalence by providing child care support for their children, and they showed a 'repayment provision' tendency. Some working mothers and most of the full-time mothers said they would allot 'limited provision' by excluding child care support for their children. Those who were aware of this ambivalence issue sought 'reasonable provision' for their children. Depending on these results, several suggestions are presented to solve the ambivalence.

The purpose of this study is to draw employee support program at the company level through field survey of foreign laborers' satisfaction level of working life. To analyze the factors that determine working life satisfaction, regression analysis was conducted. Satisfaction level of working hours(t=2.469), living environment(t=2.140), post offices/banks (t=3.024) showed a statistically significant. Also these variables, working hours, living environment, post office/banks are verified to be very important for improving the level of their working life. Through these findings we can understand that employee support activities, providing user-guide of bank and post office, compliance with standards for working hours, improvement of the living conditions (accommodation, meals, etc.), the leisure time program support, the children care support and active utilization of foreign workers and strengthen the educational program, are necessary to improve the satisfaction level of foreign laborers' working life in Korea. It is recommended that managers need to recognize that careful consideration of living and working condition could contribute to stable settlement and increase working life satisfaction for the foreign workers at company level.

This study was conducted for the purpose of suggesting support measures for providing medical library services in Korea by investigating cases of support services provided at U. S. medical school libraries to obtain research grants for users. Suggestions based on the survey results are as follows. First, medical libraries need to support research grant services as an area of research support services. Second, it is necessary to provide various services related to subsidies. Third, there is a librarian in charge of grants services. Fourth, cooperation between the medical library and departments and organizations inside and outside the university is necessary. Fifth, at a national level, active fund activities are needed from various government agencies, private foundations, and non-profit organizations.

Small-and-medium sized enterprises(SMEs) represent quite a large proportion of the industry as a whole in terms of the number of enterprises or employees. However researches on information system so far have focused on large companies, probably because SMEs were not so active in introducing information systems as larger enterprises. SMEs are now increasingly bringing in information systems such as ERP(Enterprise Resource Planning Systems) and some of the companies already entered the stage of ongoing use. Accordingly, researches should deal with the use of information systems by SME s operating under different conditions from large companies. This study examined factors and mechanism inducing faithful appropriation of information systems, in particular integrative systems such as ERP, in view of individuals` active feedback-seeking behavior. There are three factors expected to affect end users` feedback-seeking behavior for faithful appropriation of information systems. They are management support, peer IT champ support, and IT staff support. The main focus of the study is on how these factors affect feedback-seeking behavior and whether the feedback-seeking behavior plays the role of mediator for realizing faithful appropriation of information systems by end users. To examine the research model and the hypotheses, this study employed an empirical method based on a field survey. The survey used measurements mostly employed and verified by previous researches, while some of the measurements had gone through minor modifications for the purpose of the study. The survey respondents are individual employees of SMEs that have been using ERP for one year or longer. To prevent common method bias, Task-Technology Fit items used as the control variable were made to be answered by different respondents. In total, 127 pairs of valid questionnaires were collected and used for the analysis. The PLS(Partial Least Squares) approach to structural equation modeling(PLS-Graph v.3.0) was used as our data analysis strategy because of its ability to model both formative and reflective latent constructs under small-and medium-size samples. The analysis shows Reliability, Construct Validity and Discriminant Validity are appropriate. The path analysis results are as follows; first, the more there is peer IT champ support, the more the end user is likely to show feedback-seeking behavior(path-coefficient=0.230, t=2.28, p<0.05). In other words, if colleagues proficient in information system use recognize the importance of their help, pass on what they have found to be an effective way of using the system or correct others' misuse, ordinary end users will be able to seek feedback on the faithfulness of their appropriation of information system without hesitation, because they know the convenience of getting help. Second, management support encourages ordinary end users to seek more feedback(path-coefficient=0.271, t=3.06, p<0.01) by affecting the end users' perceived value of feedback(path-coefficient=0.401, t=6.01, p<0.01). Management support is far more influential than other factors that when the management of an SME well understands the benefit of ERP, promotes its faithful appropriation and pays attention to employees' satisfaction with the system, employees will make deliberate efforts for faithful appropriation of the system. However, the third factor, IT staff support was found not to be conducive to feedback-seeking behavior from end users(path-coefficient=0.174, t=1.83). This is partly attributable to the fundamental reason that there is little support for end users from IT staff in SMEs. Even when IT staff provides support, end users may find it less important than that from coworkers more familiar with the end users' job. Meanwhile, the more end users seek feedback and attempt to find ways of faithful appropriation of information systems, the more likely the users will be able to deploy the system according to the purpose the system was originally meant for(path-coefficient=0.35, t=2.88, p<0.01). Finally, the mediation effect analysis confirmed the mediation effect of feedback-seeking behavior. By confirming the mediation effect of feedback-seeking behavior, this study draws attention to the importance of feedback-seeking behavior that has long been overlooked in research about information system use. This study also explores the factors that promote feedback-seeking behavior which in result could affect end user`s faithful appropriation of information systems. In addition, this study provides insight about which inducements or resources SMEs should offer to promote individual users' feedback-seeking behavior when formal and sufficient support from IT staff or an outside information system provider is hardly expected. As the study results show, under the business environment of SMEs, help from skilled colleagues and the management plays a critical role. Therefore, SMEs should seriously consider how to utilize skilled peer information system users, while the management should pay keen attention to end users and support them to make the most of information systems.

This study not only investigates emergency medical personnel's posttraumatic stress(PTS), social support, work burden, and coping style but also identifies related factors which were exerted influence on PTS and active coping method of emergency medical personnels among the firefighters. The data were gathered from 143 emergency medical personnels who were receiving training. The data were collected by IES-R, consisting of twenty-two questions that determine the level of PTS, method used in Cho's research(2000) that deal with work burden, method used in Oh's article (2006) relating to social support, and sixty-two questions that deals with coping methods. Then the data gathered were analyzed using SPSSWIN 14.0 program. PTS of general characteristics showed significant difference in age, marriage status, education, and position. High risk group of PTS was 74(51.7%). Work burden, active and passive coping method, and three symptoms in PTS are significantly high(p=0.000) in high risk group. PTS was correlated with work burden(r=0.508, p=0.000), active coping method(r=0.375, p=0.000), and passive coping method(r=0.505, p=0.000) but not with social support. Related factors of PTS were work burden(0.371) and passive coping method(0.366). Also related factors of high risk group of PTS were work burden(odds ratio=1.064, 95% confidence interval:1.031-1.103) and passive coping(odds ratio=1.050, 95% confidence interval:1.022-1.080). Related factors of active coping method were PTS(0.392) and social support(0.158). To minimize the PTS of emergency medical personnels, the new policy should decrease their work burden and passive coping method and strengthen the social support to encourage active coping method.

This study investigated characteristics of children's coping behaviors in the context of perceived controllability of stress in hassles with parent(s), friend-alienation, friend-conflict, and in learning situations. The subjects were 489 sixth grade children selected from seven elementary schools in Seoul. Statistical analysis was by ANOVA, Scheffe' test, and MANOVA. Major findings were that (1) Active, passive, aggressive, and avoidant coping differed by perceived controllability of stress in all 4 stress situations. The children who perceived a higher level of controllability were more active, and less passive, aggressive, and avoidant in coping with each hassle. (2) Perceived controllability was higher in learning related than in friend-conflict situations. Active, passive, and social support seeking coping behavior was higher in learning related stress situations than in friend-conflict situations. Avoidant coping behavior was lower in learning related than in friend-conflict situations.

Application of the filtered-x Least Mean Square(LMS) adaptive filter to active noise control requires to estimate the transfer characteristics between the output and the error signal of the adaptive controller. In this paper, we derive the filtered-x adaptive noise control algorithm and analyze its convergence behavior when the acoustic noise consists of multiple sinusoids. The results of the convergence analysis of the filtered-x LMS algorithm indicate that the effects of the parameter estimation inaccuracy on the convergence behavior of the algorithm are characterized by two distinct components Phase estimation error and estimated gain. In particular, the convergence is shown to be strongly affected by the accuracy of the phase response estimate. Simulation results are presented to support the theoretical convergence analysis.

This study investigated the relationships among factors in the caregiving process for caregivers with older parents. A model was presented to help identify some of the dynamics in he family caregiving process Fifty-nine caregivers participated in the study. They were adult chldren who were currently providing care to at least one older parent. Using LVPLS program support for the proposed structural equation model was found through the identification of paths among the variables, The findings indicated that the experience of life events was negatively associated with perceptions and positively with active coping A positive relationship was found between perceptions and active coping. Past relationships had positive effects on perceptions and relationships with parents. Active coping was negatively associated with the relationship with parents. whereas perceptions were not a good predictor for the relationship with parents. The results of the family caregiving process model demonstrated that past relationships and perceptions of caregiving were related to current caregiving experiences with older parents.
