The purpose of this study is to assess the development, current states, and problems of MEDLIS document delivery service. With the analysis of MEDLIS transaction data from 2001 to 2011, we identified continuous usage decrease, unbalanced contribution by type of institution, high dependence on back issues, use differences among subfields of medicine, relatively low success rate, and various reasons for failure. Based on the results, recommendations for the maintenance of union catalog database, technical support for search capability enhancements, establishment of back issue archiving policy, user training and publicity, and membership expansion are suggested to promote the service.

Representing knowledge uncertainty , aggregating evidence confidences , and propagation uncertainties are three key elements that effect the ability of a rule-based expert system to represent domains with uncertainty . Fuzzy set theory provide a good mathematical tool for representing the vagueness associated with a variable when , as the condition of a rule , it only partially corresponds to the input data. However, the aggregation of ANDed and Ored confidences is not as simple as the intersection and union operators defined for fuzzy set membership. There is, in fact, a certain degree of compensation that occurs when an expert aggregates confidences associated with compound evidence . Further, expert often consider individual evidences to be varying importance , or weight , in their support for a conclusion. This paper presents a flexible approach for evaluating evidence and conclusion confidences. Evidences may be represented as fuzzy or nonfuzzy variables with as associat d degree of certainty . different weight can also be associated degree of certainty. Different weights can also be assigned to the individual condition in determining the confidence of compound evidence . Conclusion confidence is calculated using a modified approach combining the evidence confidence and a rule strength. The techniques developed offer a flexible framework for representing knowledge and propagating uncertainties. This framework has the potention to reflect human aggregation of uncertain information more accurately than simple minimum and maximum operator do.

This research examnied the roles, the strategies and the influence of labor unions on the pension reform. In Italia labor unions were important actors in pension reform politics during 1990s, but in 2004 labor union was excluded from the pension reform. This difference is not only related with diffusion of the leftist party but also the experience of pension benefit retrenchment of the pension reform in 1995 in which labor unions had initiatives. Labor unions choose their strategies, social dialogue or mass struggle, depending on the attitudes of government. After change of government following the failure of the pension reform in 1994 Italian government tried social dialogue. In Dini reform in 1995, laborunions had initiative in making pension reform plan. Labor unions obtained member's approval using membership vote. It had repressed opposition from militant sectors effectively. However Labor unions concentrated on the issues of transition measures and protecting vested rights in seniority pension ignoring problems of contribution evasion of small-firm workers and benefit adequacy of young workers. Even when labor unions leaded social concertation processes and pursued union democracy, labor unions' influences on the pension reform had fundamental limitations.

This study investigated the working conditions and job satisfaction of school cafeteria, according to their employment type in Chonbuk, South Korea. Self-administered questionnaires were collected from 401 elementary, middle, and high school cafeteria employees. The data showed significant differences between regular and irregular employees. These factors were: previous work experience (p<.001), type of school (p<.001), the style of foodservice at a school (p<.001), the type of foodservice system (p<.05), and the number of meals served each day (p<.001). The working conditions for regular and irregular employees were significantly different with regard to several factors: these were union membership (p<.01), how they were paid (p<.05), their total working hours (p<.01), and difficulty of using their holidays (p<.01). Approximately 80.5% of the subjects were dissatisfied with the working conditions after the introduction of countermeasures for irregular employees. Results indicated that the average employee job satisfaction level was 2.53, but that there were not significant difference in the level of job satisfaction when comparing regular and irregular employees. The item employees were most satisfied with was having responsibility over meals for young students (3.37). They were least satisfied with their salary (2.00). An interesting issue for future study would be to determine the factors that could improve job satisfaction whilst satisfying the employees' needs which in turn would improve the quality of foodservice.

According to the survey results on non-standard employment, most of the non-standard workers are women and work at service jobs and some jobs that do not require firm-specific skill. Also wages of non-standard workers appear to be lower than those of standard workers by 10~19%. Non-standard workers are very much likely to be excluded from beneficiaries of economic growth because job contents and ability are not important relatively as criteria in determining their basic wage and their benefits are also much lower in severance pay and bonuses, vacations, 4 social insurances, education and training opportunities. Because of very low rate of union membership, the working conditions of non-standard workers are not expected to be improvable easily by unions. It seems that the reason of the demand increase for non-standard workers is mainly because not only an individual establishment demands quantitative flexibility in employment, but also there are tendencies of being smaller in establishment size and of growing service industries macro-economically. The number of non-standard workers are expected to increase continuously in the future, too.

The purpose of this study were to determine causes of low back pain in bus drivers who usually work in prolonged sitting position and to find the relationship of back pain with general characteristics and work environmental characteristics, stress symptoms, to com맹re lordosis angle of habitual driving posture and resting posture in low back pain group and non-low back pain group, and to use this result as a basis for improvement of work environment and comprehensive rehabilitative management of low back pain. Ninety-eight bus drivers were selected from the membership of an urban transit union in Seoul. These informations were collected from May 1, 1997 to May 25, 1997 by means of structured questionnaires and X-ray findings. These data were analyzed by $x^2$ test, t-test, logistic regression using SAS. The major results were as follows: 1. Of the respondents, 66.3% of bus drivers were found to be experiencing back pain. 2. Of the respondents of low back pain groups, 78.5% reported that major cause of low back pain was due to prolonged sitting. 3. The group with experiences of frequent or continuous vibration had more low back pain (p<0.05). There were no significant differences among other work environmental factors. 4. Average stress score was significantly higher in the group with low back pain than in the group without low back pain (p<0.05). 5. The results of the logistic regression analyses were statistically significant vibration from seat and stress score among the risk factors (p<0.05). 6. Averaged lordosis angle of habitual driving posture was $7.6{\pm}14.9$ degrees in low back pain group, $16.5{\pm}8.7$ degrees in non-low back pain and averaged lordosis angle of resting sitting posture was $10.8{\pm}13.7$ degrees in low back pain, $18.9{\pm}9.6$ degrees in non-low back pain group but the difference in mean lordosis angles of two groups was not statistically significant. The results of this study indicate that professional drivers developed chronicity of low back pain due to unfit seat, poor habitual posture and stress from vibration or other risk factors. Therefore, there is need to improve work environment, i.e. enough resting, to set a seat to support lumbar spine properly and to provide comprehensive rehabilitation program including early diagnosis, proper treatment and education for self help management.

Qi is in the capacity of pivotal element to describe the life, based on the principles of remedy such as Qigong, meridian pathways, acupuncture, moxibustion and herbal medicine. The purpose of this study was to identify the status of course offered Qigong and Qigong-related clubs in 11 college of oriental medicine. For survey courses offered Status of Qigong in 11 college of oriental medicine, I checked its homepage in august 2008. And about the facts that I could not verify information from the homepage, I obtained through the phone manner. For survey Qigong-related clubs in 11 college of oriental medicine, I phoned the president of union clubs and found out Qigong-related clubs. And then I phoned the presidents of Qigong-related clubs that consented before the fact, investigated the overall situation of clubs. Nine out of 11 college of oriental medicine offered course of Qigong. All of them are opened as major in a premedical course. Six universities have practical training. Six out of 11 college of oriental medicine had Qigong-related clubs. And the number of club is 12. The number of club in Daeguhaany university, 4, is the most. The number of membership of club in Daeguhaany university, 61, is the most too. Most of them are co-majoring both Jung-gong and Dong-gong. It is considered that in lecture of Qigong, It is in a need of lecturing in a regular course with clinical contents, rather than lecturing in a premedical course with basic contents. Of spontaneous club activities, after graduation so that they can get practical help for future. I think from now on we need to investigate deeply practical rate of satisfaction and the present condition of clubs.
