Usually, cloud storage systems are developed based on DFS (Distributed File System) for scalability and reliability reasons. DFSs are designed to improve throughput than IO response time, and therefore, they are appropriate for batch processing jobs. Recently, cloud storage systems have been used for update intensive applications such as OLTP and so on. However, in DFSs, in-place update operations are not carefully considered. Therefore, when updates are frequent, I/O performance of DFSs are degraded significantly. DFSs with RAID techniques have been proposed to improve their performance and reliability. Their performance degradation caused by frequent update operations can be more significant. In this paper, we propose an in-place update method for DFS RAID exploiting a differential logging technique. The proposed method reduces the I/O costs, network traffic and XOR operation costs for RAID. We demonstrate the efficiency of our proposed in-place update method through various experiments.

Back injury is frequent in industry workers and is a common cause of productivity loss. It has been reported that the insured of industrial accident insurance tend to stay in hospital longer than that of other types of insurance. The purpose of this study was to identify factors affecting the length of hospital stay for the treatment of back injury in the workers under industrial accident insurance. The results of this study help insurers develop reasonable industrial accident insurance policy for back injury claims and prevention strategies of work-related back injury. A total of 2,949 patients whose industrial accident insurance claim has been approved for the treatment of work-related back injury from January to December 1999 were included in this study. Relationship between the length of hospital stay and characteristics of patient, work place, back injury, and hospital were assessed using ANOVA, t-test, simple linear regression and multiple resgression. The major findings of this study are as follows : 1. The average length of hospital stay(LOS) was 91.82 days, respectively. 2. Characteristics of Patient LOS of male patients was longer than that of female patients, there was positive correlation between age and LOS and between average wage and LOS. Working period was negatively correlated with LOS. Distance from resident to hospital was positively correlated with LOS and LOS was significantly different dependign on type of duty. 3. Characteristics of Work Place LOS was significantly different depending on types of industry and geographical region of work place. Size of work place was positively correlated with LOS. 4. Characteristics of Back Injury Occupational back pain required shorter LOS compared with back injury due to electric shock. Number of concomitant illnesses and severity of disability were positively correlated with LOS. 5. Characteristics of Hospital Patients treated in community hospitals required significantly longer LOS. Treatment in hospitals with rehabilitation program required decreased LOS. This was more prominent as number of physicians specialized in rehabilitation. 6. Multiple regression analysis revealed that distance form resident to hospital, geographical region of work place, size of work place, number of concomitant illnesses, severity of disability, and type of hospital were factors affecting LOS.

Community is crucial for human beings not only because they are born with communal self but also because social cooperation is more efficient than competition in many cases. Human beings are defined as Homo communicus living in residential community which is important for the fulfillment of their primary needs. Residential community is an 'intimacy zone' where personal and emotional interactions are made. This study aims at examining the health of residential community in Korea by exploring the level of place attachment and neighborhood trust. Previous studies indicate that place attachment and trust are influenced by three dimensions such as residents' characteristics, house types and regional environment. This study conducted a nationwide questionnaire survey and it shows that place attachment moulds neighborhood trust. The results of path analysis demonstrates that place attachment and trust appear high in detached house areas. Age of residents also gives positive influence on the level of place attachment and neighbourhood trust. This result gives significant policy implications for the development of residential community in Korea. Residential community as an intimacy zone has been eroded and desperately needs to be revitalized. For this, more concern should be given to the issue of desirable size of residential community and the types of houses. Detached house area must be supported by governmental policies.

Considerations of how to facilitate aging-in-place(AIP) are becoming increasingly pertinent as care-givers are overwhelmed by an aging population. Aging friendly home-care services combined with IT can satisfy the needs of the elderly suffer from chronic diseases such as depression and dementia. Therefore, we propose future smart phone services and application technologies which can estimate emotional states of the aged and respond to the desire to be happy with mental health, connectedness and consolation from peoples. Firstly, we introduce depression measurement techniques to estimate the severity of depression using multiple sensors. At second, the emotional responding services are categorized to four parts and the details are described. Lastly, we propose the process to implement emotional communication and the application techniques(services) to fulfill the emotional satisfaction and mental healthcare for AIP using smart phone as a mediator.

In this study, satisfaction with salary of the clerical saff in health care organization was analyzed with a view to provide data contributive to efficient wage management for the clerical staff of hospitals. For the analysis, it was investigated if there is any difference in satisfaction with wage depending on the individual and environmental characters as well as comparative factors perceived by self or by others in-and outside the working place. The findings of the analysis may be summed up as follows: First, in support of the hypothesis that the satisfaction with wage of the clerical staff in hospitals will individual factors, statistically significant difference were found in the satisfaction with wage depending on age and career, but there was little significant difference depending on gender and education. Thus, the hypothesis I in this study can be partly adopted. Second, with regard to the hypothesis that the satisfaction with wage of the clerical staff in hospitals will vary with environmental variables, significant differences were found in terms of comparative factors perceived by self or by others inside the working place and those perceived by others outside the working place, and significant difference was also shown in the comparative factors perceived by others outside the working place. Whereas, however, there was no significant difference in the satisfaction with wage depending on the position, which led to the partial adoption of the hypothesis II. This study has following limits in search of difference in satisfaction with wage of clerical staff in hospital depending on individual and environmental variables: the sample is too small to represent the general wage level satisfaction of the whole health care organizations, since the survey hasn't covered the wage level and management of the employees in all hospitals; the professional attitude and rate of fluctuation that are closely connected with the wage level are not considered.
