Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

This study was carried out to investigate the effects of Cervi Cormu on the hemopoietic functions in Sprague-Dawley rats. 7, 12-Dimethylbenz[a]anthracene(DMBA) was administered subcutaneously to Sprague-Dawley rats by interscapular single injection of 100㎍/g of body weight in order to induce hypofunction of hemopoietic organs. Freeze-dried powder of Cervi Cornu was continuously administered, perorally, as a concentration of 20㎎/200gm B. W. in saline. Experimental and control groups of rats were sacrificed on day 7, 14 and 21 following the injection of DMBA. The results obtained were summarized as follows: Body weights of experimental and control groups showed similar values. Thymus weights of control and deer horn extract(DHE)-treated groups showed similar values, but those of DMBA-treated groups were remarkably decreased in comparison with control groups. Spleen weights of DHE-treated groups were moderately increased comparing to those of control groups, but those of DMBA-treated groups were remarkably decreased in comparision with control groups. RBC numbers of experimental and control groups showed similar values. Hb and Hct in DMBA-treated groups and DHE-treated groups following DMBA treatment were decreased at 3 weeks in comparison with control groups. MCV in DMBA-treated groups were decreased comparing to control groups. MCH and MCHC in experimental and control groups showed similar values. Albumin, BUN, and total protein in experimental and control groups showed similar values. Total cholesterol, alkline phosphatase, and creatinine were decreased in DHE-treated groups comparing to those of control group through the experimental period. SGOT and SGPT were decreased in DHE-treated groups, and those were decreased in DMBA-treated groups and DHE-treated groups following DMBA treatment at 2 and 3 week, comparing to those of control groups.

勤勞契約의 侵害와 危險勤勞의 拒否

A considerable body of law has grown up about the sulject of interference with commercial or economic relations, Included in the field of such relations are of course existing employment contracts, and agreements. It is usually said that tort liability may be imposed upon a defendant who intentionally and improperly interferes with the plaintiff's rights under a contract with another person if the interference causes the plintiff to lose a right under the contract or makes the contract rights more costly or less valuable. The Iaw of torts, and especially the Iaw of contract interference, was once of considerable significance in labor-management disputes. A Strike might interfere with the contract rights of a worker who did not wish to observe the strike. The most common example is the case of iniury to a person who then loses wages as a result of the injury. Recovery for lost wages is commonly permitted for negligent injury, not on the theory that there was a negligent interference with the worker's performance of his contract, but on the theory that the interference, and the wage loss, resuted from the tort to his person. Health and Safety factors may justify the employee in leaving his employment. Occasions might arise when an employee is confronted with a choice between not performing assigned tasks or subjecting himself to serious injury or death arising from a hazardous condition at the workplace. If the employee, with no reasonable alternative, refuses in good faith to expose himsel to the dangerous condition, he would be protecteel against subsequent discrimination. The employee should have asked his employer to correct the dangerous condition and his refusal to work must be in good faith. The interference with employment contract should be avoided, and the measures for protecting employees should be taken.
