Background: A number of patients complain of lower back pain due to facet joint problems, and radiofrequency thermocoagulation (RFTC) of medial branches is known to be an effective method of relieving pain caused by the problems. However, objective outcome assessments for this modality are limited so far. Therefore, the authors investigated the effect of the RFTC on the low back pain. Methods: The object of this study was 25 patients who had facet joint syndrome and underwent RFTC. Pain relief was estimated at 2 weeks, 6 weeks, 3 months, and 6 months after the procedure using a visual analog scale (VAS), and was regarded to be successful if pain reduction exceeded 50% on the VAS at 6 weeks. Results: Seven of the 25 patients did not respond favorably to RFTC application and their pain reduction was less than 50%. Of the 18 patients who showed a successful response, 17 had a favorable result up to 3 months and 15 patients up to 6 months after the procedure. Conclusion: Our result showed that lumbar medial branch rhizotomy using RFTC, is an effective treatment modality for patients with lumbar facet joint syndrome, and showing a successful response its effect is maintained for at least 6 months after the procedure in most patients.

This study was designed to distinguish by the characteristic difference and the degree of symptoms such as fatigue, pain, coping to pain, and efficacy on pain, and to offer descriptive data for nursing intervention for improving coping ability to pain along each characteristics of disease in chronic arthritis and systemic lupus erythematosus. The subjects were 135 outpatients in the hospital for rheumatic disease in H-University, Seoul. The data were collected by structural questionnaire, from April 29 to June 29, 1999. The results were that the fatigue score was high in the OA patients while the RA patients and SLE patients experienced middle range of fatigue score, but which was not statistically different. Although the RA patients felt higher pain than other diseases, they have well coped with their pain than the others. In efficacy on pain the SLE patients had higher score than others but all of the disease showed lower score. No statistically significant difference among the three croup was recorded in efficacy on pain. Therefore, pain management in the RA patients was primary nursing intervention because they felt severe pain and have well coped with pain while they had lower pain efficacy score than the others. It is also important that fatigue management and coping strategies on pain for the OA patients and SLE patients are specially supportive in the nursing intervention.

Database design is the base of the entire process related to the database, and the well-designed database schema has a great effect on the system performance. So, there's a growing need for the automatic schema generation system. In this paper, database design automation system is implemented which translates automatically OMT based database model to relational database table. For developing this system, transformation rules of OMT into RDB schema are suggested which satisfy normalization and integrity constraints. This automation system can be used efficiently in the area of training database system and applying database design in actual business fields.

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps: one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

Most anticancer drugs so far used have brought many side effects to the host, which is inevitable since they can not specifically distinguish between cancer cells and rapidly dividing normal cells. Therefore, it is very important to develope a chemopreventive agent proven for a long period of time not to toxic to normal cells. Since garlic has been attracted interests from many areas of cancer researchers as a potent anticancer agent, attempts were made to see the direct cytotoxic effect of garlic to human osteosarcoma cell lines. The present study was designed to investigate the effect of garlic on the two cell lines of rapidly growing osteosarcoma with comparable doubling time of 20 hours, namely KHOS/NP and MG-63. Four different garlic preparations commnly used in the Koreans, that is, raw and heated garlic dissolved in distilled water, raw and heated garlic dissolved in saline were compared in thier cytotoxic effect to the KHOS/NP and MG-63. The results obtained were as follows. 1. Raw garlic dissoved in distilled water showed the best cytotoxic effect among four different preparations of garlic used in this study. 2. The cytotoxic effect of garlic to the osteosarcoma was different, to the cell lines showing mostly more effective to KHOS/NP than to MG-63. 3. To KHOS/NP, the cytotoxic effect of garlic was markedly increased with concentrations but not with incubated time. 4. To MG-63, the cytotoxic effect of garlic w3s increased both with concentrations and incubated time. 5. The difference of inhibitory action of garlic between KHOS/NP and MG-63 was marked when heated garlic in saline was treated at high concentration(0.1875g% ) for 48 hours.
