Purpose: This study was conducted to estimate the job stress and depression of female and male service workers and to determine the predictors influencing depression. Method: In this cross-sectional study, the data were collected from hotel, wholesale, and insurance companies. A total of 244 workers were recruited. Among them, 118 were female workers. A self-administered questionnaire was consisted of personal characteristics, job stress, daily life stress, social support, and depression. Depression was measured using a CES-D Korean version. Result: The average job stress of female workers was higher than that of male workers (P<.05). The average depression scores of female workers were higher than those of male workers, but the difference was not statistically significant. Multiple regression analysis showed that role conflict and low social support were significant predictors of depression in female workers. In male workers, role conflict, low social support, and under-utilization of abilities were significant predictors of depression. Conclusion: The results of this study suggest that depression of service workers may be prevented by creating a workplace environment that focuses on role conflict and social support. Also, health providers should consider the vulnerability of working women to job stress.

The use of an efficient packet scheduling scheme for a forward link in satellite communication networks is very important to support fairness for each return channel satellite terminal (RCST) and the service differentiations for user traffics. To support fairness and QoS for each RCST with service-level agreement (SLA), the Adaptive Coding and Modulation (ACM) system in a satellite hub has to process packets with considering modulation and coding (MODCOD) and packet types. Although a DVB-S2 system with ACM scheme has higher transmission efficiency, it cannot offer fairness or quality of service (QoS) to RCSTs. Because the data are transmitted with high MODCOD in regions with clear skies, while data are transmitted using low MODCOD in regions experiencing rain events. In this paper, we propose a two-step scheduling scheme offering fairness and QoS to RCSTs, while minimizing a decrease in throughput. The proposed scheme is carried out performance evaluations using a computer simulation. As results of this simulation, the proposed scheduler was shown to support bandwidth fairness to an individual RCST, and provide a level of QoS differentiation for user traffics.

This study was trying to find the differences of the levels of e-commerce system satisfaction and a relationship between system satisfactions and behavioral intention to use e-commerce system continuously. Based on the previous studies, we identified the factors of system satisfaction that were consist of system readiness, accuracy, content, ease of use, timeliness and IT Support. The system satisfaction levels of martial status and the training status of hospitals had significant differences. In martial status, un-married managers had higher levels of ease of use and timeliness than the married. In this result, we might consider an age effect for younger persons are more likely to use IT and have more satisfaction perceptions. Rather than training hospitals, non-training hospitals had higher level of ease of use and IT support, which could be interpreted as e-commerce systems of training hospitals might not match their own managerial purposes and need an improvement of their system functionalities. This study also identified that the factors of system satisfaction has a relationship with behavioral intentions. Except accuracy and IT support of all six system satisfaction factors, four factors were significantly correlated with system usage intentions in their e - commerce works.

I. Background The problem of discharging patients from hospital have been well documented in the literature over the last 20 years. They included poor communication between hospital and community, inadequate notice of discharge, over-reliance on informal support and lack of statutory support, inattention to patients needs before leaving hospital, and wasted or duplicated visits by community nurses. Most patients discharged from hospital are able to return home with little or no support, while others will require a 'package of care' to support them back to good health. Patient with complex care needs, including the frail elderly and those with mental health problems, may require continuing care in special housing, residential, or nursing homes. With this population,effective discharge arrangement is needed and the study on this problem is urgent in Korea because the Medical Reform Project is on suspension of success. II. Results of the Study: 1. Discharge service needs assessed on 360 elderly patients who were hospitalized during the survey period at four university hospitals. Patients want to know the information on disease management after discharge. Follow-up telephone service is the most frequently checked service. 2. Multidisciplinary Discharge Planning is recommended at the hospital level to reduce the readmission and decrease the length of stay. 3. Further research is needed to validate and test the assumption of the solution which is developed in this research.

In order to support a large number of mobile stations (MSs) with statistical multiplexing in cellular networks, a random access scheme is widely used for uplink (UL) bandwidth request (BR). In the design of a random access based BR scheme, there are two important requirements: short connection delay and diverse Quality of Services (QoSs) support. Such requirements are crucial for IMT-Advanced systems like IEEE 802.16m to provide various types of fourth generation (4G) data services. IEEE 802.16m provides advanced UL BR schemes for non-real time polling service (nrtPS) and best-effort (BE) service to meet the requirements of short connection time and multiple QoS level support. In order to provide short connection time and multiple QoS support, three-step and differentiated BR procedures are adopted. In this paper, a novel modelling of IEEE 802.16m contention based BR scheme is proposed that uses a 2-dimensional discrete time Markov chain. Both the short access delay three-step BR procedures and normal five-step BR procedure are considered in the model. Our proposed model also incorporates the IEEE 802.16m differentiated BR procedure. With the proposed model, we extensively evaluate the performance of IEEE 802.16m BR for two different service classes by changing QoS parameters, such as backoff window size and BR timer. Computer simulations are performed to corroborate the accuracy of the proposed model for various operation scenarios. With the proposed model, accurate QoS parameter values can be derived for the IEEE 802.16m contention-based BR scheme.

In-depth interview research and qualitative methodology were used to find changes in the experiences of family volunteer activities through the use of the Health Family Support Center. Ultimately, 143 items as sub-concepts, 42 items as sub-categories, and 10 items as subjects were found. I will also suggest alternative basic and primary data. First, using 10 subjects, the following points were evaluated in detail. I looked at what kind of changes in the volunteer activities these subjects experienced after working at the Health Family Support Center, and what the specific underlying reasons were for the changes in their family volunteer experience. These included 'community solidarity', 'family community', 'leisure and culture for the family', 'communication', 'personal relations', 'coping skills', 'growth', 'sympathy', 'positive thinking', 'future plans'. Second, families experienced a feeling of belonging as community members and the family realized the importance of their life, learned communication methods and coping skills. Third, families came to have new opportunities to grow as humans and learned a feeling of sympathy for others. Fourth, families found new paradigms to think positively about their daily life and to establish future plans. We will need more effort to empower family experiences of family volunteer activities that use the Health Family Support Center as well as supporting its staff. The following specific factors were the main mediating factors for using such a facility: family volunteer education, family volunteer service agency consulting, program planning, and managing family volunteers and other services.
