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.

In the early days, encryption and control access techniques were used to protect the ownership of media. Recently, the watermark techniques are utilized to keep the copyright of media. Digital watermarking, a concept of embedding a special pattern. uses an algorithm of inserting a watermark to protect the copyright of media. It has recently become important in various application areas. The various watermark techniques have been proposed by many authors in the last several years. However, there are not enough analysis and comparison on the previous researches. In this paper, for the understanding of the previous works and for the future related research, we try to classify and analyze the conventional watermark techniques from the various points of view. Currently watermark techniques based on the transfer domain, are more popular than those of the spatial domain. DCT-based methods have been most widely used among the transform based methods. However, recently wavelet-based watermark techniques are becoming main research topic. With wide use of internet, effective audio and video watermarking researches are also required.

In order to ascertain the safety of the systemic insecticide carbofuran - treated crops. garlic, peanut and potato were collected randomly from markets near the major producing farms and analyzed for the residues of carbofuran and its main metabolite, 3-hydroxycarbofuran. The in vitro metabolism of carbofuran in phosphate buffer extracts of the crops was investigated. The results obtained were as follows. 1.The recoveries of carbofuran and 3- hydroxycarbofuran from the spiked samples were 92~ 100% in all samples. The detection limit and minimum amount of carbofuran detected were 0.02ppm and 0.1ng, and those of 3-hydroxycarbofuran 0.06ppm and 0.3ng, respectively. 2.Two mature garlic samples out of 20 contained 0.13 and 0.07ppm of carbofuran, respectively, showing a detection frequancy of 10%. The residue level was less than the maximum residue limit(0.5ppm) set by the health authorities in Korea. Only one mature garlic sample out of 20 contained 0.13ppm of 3-hydroxycarbofuran. 3.The residues of carbofuran and 3-hydroxycarbofuran in the immature garlic, peanut and potato samples were less than the detection limits. 4.The application of carbofuran to the fields of garlic, peanut and potato would be safe, considering that the estimated maximum acceptable daily intake of carbofuran from garlic was 0.0007mg which is 0.13% of the maximum acceptable daily intake(0.55mg) . 5.Carbofuran was hydrolyzed in vitro mainly to carbofuran phenol(m/z 164) in phosphate buffer extracts of the three crops in contrast to the major oxidative metabolism in situ. The amount of the metabolite increased with the incubation time.

It is said that Korean teacher education is facing some critical Problems. We think that we can get some imformations from the reexaminations on the recent reforms in Japaness teacher education system. 1) As the basic orientation of teacher education, we need to distinguish open system and closed system; teacher education in all college level and teachers college level. Institutional improvements should be directed to democratization and specialization; abuses in massproductive teacher education are required to correct. 2) In principle, teacher education should be enforced solely in regular college level; through strengthening teaching method course, teaching subject courses, and student teaching practices, professionally of teacher education must be elivated. 3) As teacher education heavily depends upon teacher employment directly or indirectly, the plan of the teacher demand and supply is needed to be reasonable. And incentive systems for teachers are demanded. 4) In-service education should be qualified to enhance the autonomy of teaching profession. 5) The Co-research between colleges, educatibnal institutes, and schools is expected to strengthen and enlarge action research.
