  • Background Venous anastomosis is an important component of digital replantation, but is not always feasible, as some cases require external bleeding to treat venous congestion in the replanted tissue. In the present study, we evaluated the relationship between the number of vein anastomoses and the survival rate of Tamai zone I replantations. Methods A retrospective review was performed of all patients who underwent replantation of a fingertip amputation between 2014 and 2016. Patient charts were reviewed for demographic information, the mechanism of injury, the number of venous anastomoses, and the use of anticoagulation, external bleeding, and/or leeches. The cohort was divided into 3 groups depending on the number of venous anastomoses: no veins (group 1), a single vein (group 2), and 2 or more veins (group 3). Survival rates and external bleeding rates were analyzed across the groups. Results The review identified 143 fingertip replantations among 134 patients. The overall survival rate was 94% (135 of 143). Failures were due equally to venous complications (n=4, 50%) and to arterial complications (n=4, 50%). Our analysis did not identify any correlation between the number of veins anastomosed and the replant survival rate (P=0.689). However, a greater number of anastomoses was associated with a significantly lower frequency of external bleeding (P=0.017). Conclusions The number of venous anastomoses was not correlated with the survival rate. However, a greater number of venous anastomoses was associated with a decreased need for external bleeding, corresponding to a significant decrease in the need for postoperative monitoring and leech therapy.

  • Purpose: We intended to observe relation between general symptom and the number of uterine myoma. Methods: We surveyed 948 women from 35 to 45 years old who had received Korean oriental medical questionnaires about general symptom pattern and pelvic ultrasonography at Kyung-Hee university medical center from May, 2007 to October, 2008. After we divided women into three groups (Mono-uterine myoma, Bi-uterine myoma & uterine myoma above 3) by ultrasonography result, we compared general symptom pattern according to the number of uterine myoma. For statistics, we used Kruskal-Wallis Test, SPSS 13.0 for windows. Results: In relation to sleep pattern, severity of dreaming & awaking showed statistical significance according to the number of uterine myoma. In relation to digestion pattern, appetite & heartburn showed statistical significance according to the number of uterine myoma. In relation to evacuation pattern, hardening of stool showed statistical significance according to the number of uterine myoma. In relation to sweating pattern, severity of refreshing after sweating showed statistical significance according to the number of uterine myoma. In relation to the other patterns, hypertonicity of nape neck showed statistical significance according to the number of uterine myoma(p<0.05). Conclusion: The result showed that prevalence of uterine myoma had to be considered in respect of sleep, digestion, evacuation and sweating pattern. we need further study based on this preliminary result.

  • Purpose: As the medical environment changes, the size of medical facilities continues to change. Of course, it is not easy to analyze the correlation between changes in the medical environment and changes in facility size in a rigorous scientific method. However, the results of investigating and analyzing changes in the size that occurred for any cause be able to serve as important references for future medical facility architectural plans. Methods: This study surveyed 68 general hospitals in Seoul for 15 years from 2005 to 2020. The change in the number of beds was investigated with data from the Ministry and Welfare. The gross area change was confirmed by analyzing the of all hospitals. Results & Implications: As a result of the survey, general hospitals in Seoul show a common phenomenon in which all hospitals except one case have expanded their size in the direction of increasing the gross area per bed over the past 15 years. However, in the method, a relatively small hospital with less than 500 beds mainly chose to reduce the number of beds. Large hospitals increased both the number of beds and the gross area, however showed a significant increase in the gross area.

  • This study analyzed efficiency by utilizing DEA analytical technique centering on materials for 2009 of 20 major university hospitals in capital area. Input variables were utilized professor & full-time doctor, resident, nurse & number of bed hospitals. Output variables were analyzed by dividing number of annual outpatients & number of annual inpatients, and annually total outpatient profit & inpatient profit into a model of the standard for number of patients and the standard for medical profit. DEA analysis was elicited efficiency score by applying CCR, BCC, BFG, scale profit, and SE model. Through t-test after eliciting efficiency score, the implications were suggested by comparing efficiency between DMU in Seoul and DMU in capital area, by comparing between high-class general hospitals and general hospitals, and by comparing between high-class general hospitals in Seoul and 5 big hospitals. As a result of analysis, the major university hospitals in capital area showed high efficiency as a whole close to "1," but indicated low efficiency relatively in CCR field. Thus, the expansion in scale within capital area was indicated to reach the limit. Second, in a model of analyzing the standard for number of patients, the medical institutions, which are being operated efficiently, were indicated to be 10 DMUs. In the standard for medical profit, 12 DMUs were analyzed to be operated efficiently. Third, the efficiency in general hospital was higher than high-class general hospital. Thus, the efficiency of operation was indicated to be more important than scale. Also, large high-class hospitals(big 5) where are located in downtown Seoul showed the higher efficiency than other general high-class general hospitals, but were indicating very low efficiency in some DMUs. Fourth, as a result of generalizing and evaluating the number of patients and the medical profit, the efficient DMU was indicated to be more when analyzing on the basis of medical profit than the standard for number of patients. Thus, major university hospitals in capital area were indicated to make more effort for section in medical profit. Based on the analytical results of efficiency, a strategy for reinforcing efficiency in inefficient DMU was indicated to be needed a strategy of creating customers for promoting number of patients and a strategy for making operation efficient for increasing profitability.

  • Let $g(n,\;l_1,\;l_2,\;d,\;t,\;q)$ be the number of general4-regular graphs on n labelled vertices with $l_1+2l_2$ loops, d double edges, t triple edges and q quartet edges. We use inclusion and exclusion with five types of properties to determine the asymptotic behavior of $g(n,\;l_1,\;l_2,\;d,\;t,\;q)$ and hence that of g(2n), the total number of general 4-regular graphs where $l_1,\;l_2,\;d,\;t\;and\;q\;=\;o(\sqrt{n})$, respectively. We show that almost all general 4-regular graphs are 2-connected. Moreover, we determine the asymptotic numbers of general 4-regular graphs with given connectivities.
