Ubiquitous computing environment means the computing environment that has taken its position so closely with the ordinary living so much like air or water. In building up the U-Korea, one of the important issues is the social issue from the drastic increase of senior population. The contemporary society has its distinct trend in increase of senior household following the nuclear family orientation, increase of working parents with the advancement of women in society, unable to support seniors for long distance or short distance of business trip and other reasons that the need of senior welfare has been ever more felt. Accordingly, the Ministry of Government Affairs and Home Administration has developed the wireless paging system to make prompt response system for 119 Rescue when the single senior is encountered with emergency situation that is has been widely provided for the socially neglected people such as single senior, the disabled persons and others. Currently, the wireless paging system is operated as the sub-system for emergency rescue information system, but due to the lack of reliability of product, problems of terminal portable transmitter, receptor and others, rejection of beneficiary and lack of knowledge in use, insufficient management and supervision of managing officers, the efficiency has been declined that there is a need of development for the system. Therefore, this study proposes the context aware information structure of the subject of ubiquitous wireless paging system required for the development of the wireless paging system model of ubiquitous environment that improved the problems of currently operated wireless paging system.

The nineteenth century was a watershed - the extreme point of difference in the style of fashion dress and in the roles men and women played in society. This conviction has its roots in the socioeconomic changes of the 19th century and the industrial revolution, and the new working bourgeoisie' value, fashion and taste were on the rise. The bourgeois, who was not considered as having infallible taste, was looking for its own style, while on the other hand it was competing with the nobility. Therefore bourgeois' own etiquette and taste were appeared. There was ideals which the middle classes were hungry for, and it became the basis of judging an individual. The bourgeois tried to get social approval and used fashion was the mean of it. Bourgeois women fashion has a funtion as a complete symbol of the status, wealth and leisure in a patriachal society. Not only the Bourgeois tried to control themselves and to achieve the virtue of moderation, chastity and obedience by the restrictive costume, but also extravagant and cumbersome dresses has a kind of compensative funtion against a sober and simple men's dress. There was a reformative movement to break out of the legal, economic and social restrictions within the confines of respectable Victorian Society. The process of reform was long and slow for not only did laws be changed but the barriers of prejudice in a society convinced of man s mental and physical superiority had to be overcome. But even though there were many difficulties, a small number of progressive women challenged the social recognition and role of women and decisively refused the restrictive and ostentative fashion. Victorian costume was also criticized in the medical and aesthetic aspect for their impracticality. As a result, more funtional and practical women's clothes has appeared, but it have resulted in a peculiar hybrid of traditional female attire in combination with the more uncomfortable aspects of men's clothes. However it was becoming an essential look for new women who were the equals of men and wanted to be treated as such.

The purpose of the study was to investigate the influences of contract foodservice managers' personal characteristics, foodservice characteristics and organizational characteristics on job satisfaction, including interpersonal relationships, self-actualization and promotion opportunity categories. A survey was administered to four hundred contract foodservice managers of five large companies and five small/medium companies in the Seoul and Kyungin areas. The final response rate was 66%(N=265), and the data were analyzed using SPSS Windows(ver. 12.0). The respondents were 76.1% female, average age 28.8 years, and 73.0% were regular workers. Contract foodservices have profit and loss contracts(69.1%), single menu types(59.6%) and buffet serving styles(37.7%). There are significant differences of job satisfaction by some personal characteristic variables(gender, martial status, age, education, position, work hours, period of working for the present company, and payroll per year) and foodservice characteristic variables(type of contract and charge of food costs). In three job satisfaction categories, foodservice managers reported the highest interpersonal relationship satisfaction, following self-actualization satisfaction and promotion opportunity satisfaction in both large companies and small/medium companies. However, foodservice managers of large companies tended to be more satisfied regarding their promotion opportunities than foodservice managers of small/medium companies(p<0.05). Work hours, number of meals served/day, male, workload, communication with the clients, relationship with co-workers, obvious role and autonomy were significant factors to increase the job satisfaction in contract foodservices of large companies. On the other hand, relationships with co-workers and males were significant factors to increase the job satisfaction in contract foodservices of small/medium companies. This research suggests that contract foodservice companies need to understand the characteristics of their managers, foodservices and organizations to enhance the job satisfaction of foodservice managers and to develop specified human resource management strategies that can be applied to each company scale.

The public health service center and its branch are, as one of public institution, responsible for providing non-profitable medical service to local residents, which can't be addressed by private medical institutes. In addition, as a planning coordinator, they need to manage local medical resources effectively to make sure local residents can be offered good-quality health service fairly and impartially. The purpose of this study was to highlight the importance of physical therapy in public health service center's successful role performance, one of treatment to which local residents had a direct access. For attaining the purpose, an investigation was made into the actual facilities of public health service center and its branches in North Cholla province, the extent of use of physicaltherapy room, and the general characteristics of physical therapists. And literatures concerned were referred to. As a result, the dominant opinion was that the current physicaltherapy room shoulder be more reinforced(38.9%) or that it should he kept as it was(46.5%). Besides, the physical therapists investigated still were serving in a poor working condition. To elevate the quality and quantity of medical service, the current way to employ expert personnels temporarily or not to guarantee the position of physiotherapists should be removed immediately. Instead, physicaltherapists should be employed as regular public official. As, in home-visit project, physiotherapist are expected to play a bigger role in rehabilitation care or the management of patients with chronic disease, the physicaltherapy room should be increased and more physicaltherapists should be provided to health service institutions.

Background: The purpose of this study was designed to find out the effectiveness of reposition sense, muscle fatigue response on lumbar spine after apply lumbosacral stabilization exercise program to 4 patients with chronic low back pain and for 12 weeks. Method: In this study the reposition sense was measured in 3 angle(60, 30, 12) of the lumbar spine motion with blind by MedX test machine and the difference of instability to lumbar vertebra segments in flexion, extension test of standing position and spinal load test Mattress Test by Spinal Mouse. The stabilization exercise program was applied 2 times a week for 12 weeks in hospital and 2 times a day for 20 minutes at home. Result: The results of the present study were that the repositioning sense was appeared the most error in 12 angles of lumbar flexion and Men was appeared to decrease an error more than female in average value of 4 angles after 12 weeks. And average error of male was decrease more than female. Thus the effects of lumbosacral stabilization exercise was improved repositioning sense of prorioceptor. Fatigue response test(FRT) results, in male, was raised muscle fatigue rate during increase weight, on the other hand female appeared lower than male. Conclusion: As a results, lumbosacral stabilization exercise was aided to improvement of lumbar spine repositioning sense and vertebra segments stabilization. It was showed the rate of decrease in typically 12 degree angle point of each 3 angle(60, 36, 12). Especially, that spine instability patients will have a risk when in lifting a load or working with slight flexion posture around 12 degree during the daily of living life and it is probably to increase recurrence rate. Thus, not only lumbar extension muscle strength but also stability of vertebra segments in lumbar spine may be very important.
