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.

The idea of industrial policy calls into question many of the economic beliefs that Americans have popularly used since the end of World WarⅡ to explain their own economic preesminence such things as their commitment to market mechanism as the supreme arbiter of economic desions, their reliance on adversarial rather than cooperative public-private relations, and their greater devotion than other peoples to free trade. The purpose of this study puts its first place on the analysis of the idea of industrial policy, and secondly identifies the four approaches on the industial policy.

The one K-family of 5 glasses was fabricated to study the dielectric properties. Room temperature measurements of the real (εreal) and imaginary (εimag.) parts of the dielectric constant for the Li₂O-B₂0₃-SiO₂₃ glass system were obtained over a frequency range from 102 to 2×104Hz. The dielectric constants were increased with decreasing frequency and increasing molar fraction of Li₂O, which could be interpreted by a bistable model of Debye's theory.

Dietary behavior, body mass index(BMI) and nutrient intake status of 185 boys and 205 girls in 3rd grade middle school students in Daegu area were analyzed. Boys were 168.6㎝ tall and weighed 61.3㎏ on the average and girls 158.5㎝ and 54.4㎏, respectively. From their BMIs, 17.9% were classified as the underweight, 54.2% as the average, 14.7% as the overweight and 13.2% as the obesity. The average energy intake per day was 2222.6 ㎉ for boys, 1796.2 ㎉ for girls which were 83.3% and 86.6% of the RDA, respectively. Composition rate of carbohydrate, protein, fat in relation to energy intake was 62.4 : 16.5 : 21.1 for boys and 58.8 : 16.0 : 25.2 for girls. Protein was taken low and carbohydrate and fat were high in this study. Particularly, fat intake rate of girls was high. Calcium, iron, vitamin A, and vitamin B2 did not meet the RDA and especially calcium was taken 63.9% for boys and 54.01% for girls. Most of the students have tendency to eat irregularly and to overeat. For the nutrients intake, calories and calcium intake were lower than the RDA regardless of gender and iron intake was not enough for girls only. In relation to BMI, obesity group students were taking lower calories and proteins than the normal students were. No consistent trend was shown for boys about nutrient intake in relation to eating speed. Students had a correct perception of their body image which was similar to that of their mothers. Nutrient average intake is under the average and the percentile under 70% of RDA was high contrary to the fact that nutrient intake like calcium and iron was exceedingly important particularly in the growth process. Therefore, nutritional education for the proper intake of nutrients was required for the students in Daegu area. Especially, education has to be focused on the balanced diet and correct food choices for the proper dietary behaviors.

The mortality rate of aneurysmal surgery had recently been reduced remarkably due to mordern microsurgical technique and refinement of the timing of operation. Despite recovery without neurological deficits, many patients remain with emotional and psychological sequelae postoperatively. We evaluated 33 patients, operated on intracranial aneurysm for recent 2 years, about quality of life and degree of cognitive function. For proper evaluation of outcome of aneurysmal surgery, in addition to the neurological outcome, psychological aspects must be considered.

This paper presents a method to reduce hysteresis in multilayer ceramic actuator by connecting the actuator with a capacitor in a series circuit. The change in hysteresis with respect to the capacitor was examined. 0.2Pb(Mg_(1/3)Nb_(2/3))O₃-0.8Pb(Zr_(0.475)Ti_(0.525)) O₃ ceramic material was used as a piezoelectric material for the actuator. Displacement of the actuator was measured in a capacitive gap sensor measuring system. In case of inserting a capacitor in a total circuit, hysteresis became dramatically decreased, and then finally the hysteresis value can be reduced below 0.2%. It was found in this present study that reducing the hysteresis in the actuator is dependent upon the characteristics of the capacitor in total circuit and also operating frequency

제1대구치는 막중한 역할을 함에도 불구하고, 청소년 이전에 건강을 상실하는 경우가 드물지 않다. 본 연구는 청소년기 이 전에 치수치료를 받게 된 제1대구치의 우식 및 수복 상태와 분포를 파악할 목적으로 시도되었다. 최근 5년간 부산대학교 치 과병원에서 치수치료를 받은 18세 이하 106명 환자의 135개 제1대구치를 대상으로 의무기록에 대한 조사를 시행하여 다음 과 같은 결과를 얻었다. 1. 평균 연령은 11.9세(남 11.5세, 여 12.5세)였고 유의한 성차를 보였으며(p<0.05), 악별로는 상악 47개, 하악 88개로 하악 치아가 더 많았다. 2. 치수 치료 전 치료 기왕력이 없는 치아는 74개, 치수 또는 수복 치료를 받은 치아는 61개였다. 그 중 재치수치료를 받게 된 경우는 22개로 치수절제술-치수절단술의 순이었으며, 단순 수복치료를 받았던 치아는 39개로 복합레진-아말감-GI- 인레이-수복물 탈락 후 미치료-열구전색 및 주조 전장관의 순이었다. 3. 병소 위치가 분류 가능한 73개의 병소 중에서는 근심면 병소가 22개, 교합면 혹은 협설면 병소 39개, 원심면 병소가 12 개를 차지하였다. In clinical dentistry, it is not difficult to meet the permanent first molars with severe coronal caries lesions in children or adolescents. The circumstances surrounding the first molars of children and adolescents are so immature and imperfect compared with those of adults. So we thought it significant to understand the status of these teeth at the moment of endodontic treatment and immediate cause of it. 106 patients with 135 permanent molars necessitating endodontic treatment in childhood and adolescence were included in this study, and the dental records and radiographs were examined. 1. The mean age was 11.9 year (male 11.5, female 12.5) and the result shows significant difference between gender(p<0.05). The mandibular teeth took more than half percentage than maxillary teeth. 2. Of 135 teeth, 45.2 percent of teeth had history of dental treatment previously and 16.3 percent of teeth showed necessity of re-endodontic treatment. 3. Of 73 teeth, 22 teeth had mesial-wall cavity causing endodontic treatment, 39 had occlusal cavity, and 12 had distal cavity.
