We report the status of wetland vascular plant species in Korea including the whole peninsula and its adjacent islands. This analysis was based on database from our previous categorized list. In all, 4,050 taxa have been reported, including 3,769 native and 281 naturalized. Of these, 479 taxa (12%) are considered as wetland vascular indicator species: 240 obligate wetland plants (OBW) and 239 facultative upland plants (FACW). Approximately 31% of those 479 taxa, i.e., 149 taxa, are labelled as aquatic macrophytes. Wetland plants, mostly herbaceous but some woody, inhabit aquatic bodies and wet meadows. Except for two OBW and six FACW taxa, the rest of the plants are summer-green only. The information provided here is valuable for making assessments of wetland ecosystem health, as well as for developing management plans to preserve and restore wetlands and their resident plant species while also creating artificial wetland environments.

Purpose: The purpose of this study was to predict the risk factors for vascular complications among patients with type 2 diabetes. Method: The data were collected from August to September, 2007 using clinical examination and questionnaires. Patients (N=101) were recruited from the endocrinology department of P University hospital in D city. Descriptive statistics, Pearson correlation coefficients and multiple linear regression were used to analyze the data. Results: The cardiovascular risk of patients with diabetes was significantly related to self care behavior, family history, and smoking status. The risk of peripheral vascular complications was not related to predictors included in the study. With multivariate analyses, significant predictors of cardiovascular risk for these patients were self care behavior, family history, and smoking status ($R^2=.40$, p<.0001). Conclusion: The findings of this study indicate that smoking cessation and improving self-care behavior are essential to reduce the risk of cardiovascular complications among patients with diabetes. To enhance self-care practices for the patients with diabetes, nursing interventions, such as telephone counseling, problem focused nursing counseling, and peer group activities should be considered.

Purpose: Surgery is the most common risk factor for pulmonary embolism (PE) in patients with a recent venous thromboembolism (VTE). This study reviewed clinical outcomes of preoperative inferior vena cava filter (IVCF) use in patients with acute VTE during abdominal-pelvic cancer or lower extremity orthopedic surgeries. Materials and Methods: We retrospectively analyzed 122 patients with a recent VTE who underwent IVCF replacement prior to abdominal-pelvic cancer or lower extremity orthopedic surgery conducted between January 2010 and December 2016. Demographics, clinical characteristics, postoperative IVCF status, risk factors for a captured thrombus, and clinical outcomes were collected for these subjects. Results: Among the 122 study patients who were diagnosed with acute VTE in the prior 3 months and underwent preoperative IVCF replacement, 70 patients (57.4%) received abdominal-pelvic cancer surgery and 52 (42.6%) underwent lower extremity orthopedic surgery. There were no perioperative complications associated with IVCF in the study population and no cases of symptomatic PE postoperatively. A captured thrombus in the filter was identified postoperatively in 16 patients (13.1%). Logistic regression analysis indicated that postoperative anticoagulation within 48 hours significantly reduced the risk of a captured thrombus (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.08-0.94; P=0.032). Conclusion: A captured thrombus in preoperative IVCF was identified postoperatively in 16 patients (13.1%). Postoperative anticoagulation within 48 hours reduces the risk of captured thrombus in these cases.

Background: Previous studies generally indicate that synchronous bilateral breast cancers (SBBC) have an equivalent or moderately poorer survival compared with unilateral cases. The prognostic characteristics of SBBC would be relevant when planning adjuvant therapies and follow-up medical surveillance. The frequency of SBBC among early breast cancers in clinical settings in Australia and New Zealand was investigated, plus their prognostic significance, using the Breast Cancer Audit Database of the Society of Breast Surgeons of Australia and New Zealand, which covered an estimated 60% of early invasive lesions in those countries. Design: Rate ratios (95% confidence limits) of SBBC were investigated among 35,370 female breast cancer cases by age of woman, histology type, grade, tumour diameter, nodal status, lymphatic/vascular invasion and oestrogen receptor status. Univariate and multivariable disease-specific survival analyses were undertaken. Results: 2.3% of cases were found to be SBBC (i.e., diagnoses occurring within 3 months). The figure increased from 1.4% in women less than 40 years to 4.1% in those aged 80 years or more. Disease-specific survivals did not vary by SBBC status (p=0.206). After adjusting for age, histology type, diameter, grade, nodal status, lymphatic/vascular invasion, and oestrogen receptor status, the relative risk of breast cancer death for SBBC was 1.17 (95% CL: 0.91, 1.51). After adjusting for favourable prognostic factors more common in SBBC cases (i.e., histology type, grade, lymphatic/vascular invasion, and oestrogen receptor status), the relative risk of breast cancer death for SBBC was 1.42 (95% CL: 1.10, 1.82). After adjusting for unfavourable prognostic factors more common in SBBC cases (i.e., older age and large tumour diameter), the relative risk of breast cancer death for SBBC was 0.98 (95% CL: 0.76, 1.26). Conclusions: Results confirm previous findings of an equivalent or moderately poorer survival for SBBC but indicate that SBBC status is likely to be an important prognostic indicator for some cases.

In recent years, the view centered conservation for eco-system is getting important rather than development from human oriented perspective. As a result, the concept "Sustainable development", that is seeking harmony between conservation and development, appeared so that we researched distribution and status of vascular plants a site of project in the Bukkyungnam substation. The main findings from the study is as follows. The vascular plants a site of project in the Bukkyungnam substation area was listed 435 taxa; 93 families, 269 genera, 377 species, 1 subspecies, 51 varieties and 6 forms. Specific plant species by floral region were total 25 taxa; Acer palmatum (Planted species), Asperula lasiantha in Class III, Caryopteris incana, Cirsium schantarense in Class II, 21 taxa (Dryopteris erythrosora, Chloranthus japonicus, Salix glandulosa, Alnus hirsuta, Quercus variabilis, Ulmus parvifolia, Clematis patens, Rubus hirsutus, Euphorbia pekinensis, Cayratia japonica, Grewia biloba var. parviflora, Vaccinium oldhami, Microstegium japonicum, Hosta capitata, Polygonatum falcatum, etc.) in Class I. Based on the list of Korean endemic plants, 10 taxa were recorded; Cephalotaxus koreana, Populus tomentiglandulosa (Planted species), Indigofera koreana, Forsythia koreana (Planted species), Paulownia coreana (Planted species), Asperula lasiantha, Weigela subsessilis, Adenophora triphylla var. hirsuta, Carex okamotoi, Lilium amabile and based on the list of the rare plants by the Forest ResearchInstitute, 2 taxa were recorded in the studied areas; Lilium callosum (Preservation priority order; No. 191), Aristolochia contorta (No. 151). The naturalized plants in this site were 13 families, 22 genera, 28 taxa and naturalization rate was 6.4% of all 435 taxa vascular plants.

Purpose: This study is to assess the involvement of vessels in lower extremity in diabetics, using color doppler ultrasonogram. Materials and Methods: Arteries of both lower extremities were divided into 3 groups-large vessel (above-knee arteries), popliteal vessel, and small vessel(below-knee arteries) -, and evaluated using color doppler ultrasonogram in 60 diabetics. In color doppler ultrasonogram, the wave forms of all vessels were divided into 5 grades; grade I was triphasic wave form, grade II was spectral broadening form, grade III was monophasic wave form, grade IV was pulsus tardus et parvus form, grade V was absence of wave. Grade III, IV, V were grouped into vessel obstruction. We reviewed the correlationships among the degree of the peripheral vascular involvement, duration of dibetes, existence of bilaterality, types of dibetes. Results: Bilateral involvement was high in both lower extremity. Luminal stenosis, vascular calcification and vessel obstruction were high incidence in the patients over ten years of diabetic duration. Prevalence of vascular calcification and vessel obstruction were high in the small vessel of ankle level. But, insulin injection was not related to the incidence of vascular abnormality. Conclusion: Color doppler ultrasonogram seems to be useful for evaluation of peripheral vascular status, decision making for necessity of additional test, periodic follow -up tool in diabetes patients.

Background: Arteriovenous malformation (AVM) which is a high-blood-flow lesion with connections between arteries and veins without an intervening capillary bed, is difficult to manage. The ear is the second most common site of extracranial AVM. However, studies regarding the management of this condition remain lacking. The purpose of this study was to share managing experiences in our center and to investigate the treatment effect through a retrospective analysis of cases. Methods: Among 265 patients with AVM treated in our vascular anomalies center between January 2008 and January 2021, 10 patients with auricular AVM were included in the study to investigate the lesion distribution, clinical stage, and treatment methods by performing a retrospective evaluation. Results: Among 10 patients, five patients had AVMs distributed in the upper half of the ear, one patient in the lower half of the ear, and four patients in whole ear, respectively. Seven patients had Schobinger stage II, and three had stage III. One patient received surgical treatment only, four patients received sclerotherapy only, and five patients received both surgical treatment and sclerotherapy. The posttreatment status was checked as controlled in two patients, improved in seven patients, persistent in one patient. There were no worsening patients. Conclusion: Auricular AVM is a disease that is difficult to manage by one specific department, thus requiring a collaborative management effort from multidisciplinary team.

Objectives & Method：Based on the statistic from January 2008 to December 2008 include 66-year-old 375 people (159 men, 216 women) who got examined in National Health Insurance Corporation, this study set a goal to establish a new health index by analyzing the relation between the cardio-cerebra vascular disease and risk factor such as obesity, smoking, exercise, alcohol consumption, blood pressure, blood sugar and cholesterol. Results：1) Examine results, health status according to gender；People who are diagnosed as abnormal health status have higher risk for both men and women. As for the detailed diseases, high blood pressure was highest followed by hyperlipidemia and obesity. In case of the women, 96.3% in bone mineral density was highest. 2) Correlation of disease and health risk factors based on gender；Correlation of disease according to gender in the obesity(p<0.001), lipid abnormalities(p<0.001), kidney diseases(p<0.001), chest diseases(p<0.05), osteoporosis(p<0.001) showed a statistically significant difference. The analysis showed that the men have more obesity and lipid abnormalities as well as thoracic disease than the women, but the women have more kidney disease than the men. As for the osteoporosis examine which is conducted only for the women, most of the women were abnormal even though it cannot compare the result according to gender. Obesity(p<0.001), alcohol(p<0.001), smoking(p<0.001) and LDLcholesterol(p<0.001) showed statistical correlation between gender and health risk factor. And only high blood pressure(p<0.001) showed a statistical correlation between gender and risk of cardio-cerebra vascular disease. 3) Risk of cardio-cerebra vascular disease related to health risk factor characteristic；Obesity assessment(p<0.001), alcohol(p<0.05), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) showed correlation between health risk factor and stroke. Drinking(p<0.001), smoking(p<0.05), exercise(p<0.001), blood pressure(p<0.001), LDL cholesterol(p<0.001) showed health risk factor and myocardial infarction. Obesity assessment(p<0.001), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) and showed correlation between health risk factor and diabetes. Obesity assessment(p<0.001), blood pressure(p<0.001) showed correlation between health risk factor and high blood pressure. Conclusion：Therefore, we have to take one step farther after the health examination. In order to prevent and reduce the risk of disease, people have to understand their health status exactly first, and correct their habit with recognizing the amount of risk related to cardio-cerebra vascular disease.
