Purpose: The aim of this study was to examine the effects of an Advanced Practice Nurse (APN)-led self-management program on cardiovascular health status among Korean women at risk of developing or progressing cardiovascular disease. Methods: This pilot study used one-group pre- and post- test experimental design. At health fairs in a community, 30 women who had one or more risk factors for metabolic syndrome were recruited and agreed to participate in the study. A total of 25 women completed the study. The intervention consisted of weekly follow-up calls and self-monitoring diary after an hour of individual counseling regarding risk factors, fast walking, and healthy diet tailored to the participants' needs. Physical activity was assessed with the World Health Organization International Physical Activity Questionnaire and a pedometer. Results: Participants showed statistically significant improvements in blood pressure, body mass index, levels of triglyceride, total cholesterol and low density lipoprotein, numbers of metabolic syndrome factors, and the 10-year CV risk estimate after one month of concentrated intervention. In addition, their physical activity behavior significantly improved after the intervention. Conclusion: This APN-led self-management program targeting modifiable risk factors by offering tailored counseling and concentrated support during the transition might be effective in preventing progression to the cardiovascular disease.

Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome that affects ectomesodermal tissues (skin, eyes, adipose tissue, and brain). The neurologic manifestations associated with ECCL are various including seizures. However, ECCL patients very rarely develop brain tumors that originate from the neuroepithelium. This is the first described case of ECCL in combination with dysembryoplastic neuroepithelial tumor (DNET) that presented with intractable seizures. A 7-year-old girl was admitted to our center because of ECCL and associated uncontrolled seizures. She was born with right anophthalmia and lipomatosis in the right temporal area and endured right temporal lipoma excision at 3 years of age. Seizures began when she was 3 years old, but did not respond to multiple antiepileptic drugs. Brain magnetic resonance (MR) imaging performed at 8 and 10 years of age revealed an interval increase of multifocal hyperintense lesions in the basal ganglia, thalamus, cerebellum, periventricular white matter, and, especially, the right temporal area. A nodular mass near the right hippocampus demonstrated the absence of N-acetylaspartate decrease on brain MR spectroscopy and mildly increased methionine uptake on brain positron emission tomography, suggesting low-grade tumor. Twenty-four-hour video electroencephalographic monitoring also indicated seizures originating from the right temporal area. Right temporal lobectomy was performed without complications, and the nodular lesion was pathologically identified as DNET. The patient has been seizure-free for 14 months since surgery. Although ECCL-associated brain tumors are very rare, careful follow-up imaging and surgical resection is recommended for patients with intractable seizures.

The objective of this study was to investigate the nutritional status, biochemical parameters, lipid and electrolytes concentrations of the enteral nutrition patients according to the duration of enteral nutrition. Eighteen neurosurgery patients in the intensive care unit (ICU) at K University Hospital were subjected in this study. The duration of enteral nutrition was classified into under or over six month of period. Anthropometric, biochemical, clinical, and dietary assessments were performed. Patients' intakes of energy and protein were insufficient, from 82% to 95% of their requirements. Mid-arm muscle circumference (MAMC) and mid-am muscle area (MAMA) were significantly lower in patients over six months of enteral nutrition than those in patients under six months. The subjects were malnourished as indicated by nutrition-related parameters such as hemoglobin, albumin, total lymphocyte count (TLC), tricep skinfold thickness (TSF), mid-arm circumference (MAC), MAMC, and MAMA. Serum chloride level of the patients eve, six months of enteral nutrition was lower (94.7 $\pm$ 3.4 mmo1/1) significantly as compared to that of patients (99.3 $\pm$ 3.5 mmol/ 1) under six months. Urinary sodium and chloride levels were lower in the longer time of enteral nutrition patients than those of shorter period of enteral nutrition patients (p < .05). While serum phospholipid level was higher in the patients over six months of enteral nutrition, other blood biochemical parameters and electrolyte concentrations did not show any differences with the duration of enteral nutrition. Neurosurgery patients in the ICU undergoing long-term enteral nutrition tube-feeding were malnourished and had a variety of metabolic complications. The duration of enteral nutrition could affect the patients' nutritional status, biochemical parameters, and electrolytes balance. The patients who require nutritional support over an extended time need the continuous follow-up care and monitoring by the nutrition support team for laboratory, clinical, and nutritional assessments.

Objective : To retrospectively analyse the surgical outcome and efficacy of the lumbar spinal surgery in sixty to older patients who failed to conservative treatments. Methods : Between July 1990 and November 1996, the authors retrospectively investigated the medical records of 46 patients who over 60 years of age at the time of surgery. The clinical severity was assessed with Prolo's grade(economic and functional). Questionnaire was sent to each patient regarding long-term effect, satisfaction, and side effects. Results : In 46 patients, 2 patients(1 case died of lung cancer, 1 case lost in follow-up) were lost. Among 44 patients (28 men, 16 women ; mean age 64 years), 22 patients underwent partial or total laminectomy, 17 spinal fusion with instruments, 2 chemonucleolysis, 2 adhesiolysis for failed back surgery syndrome, and 1 automated percutaneous lumbar discectomy. Although postoperative complications were observed in 5 patients, they were successfully managed. No deaths were documented in the perioperative periods. The average Prolo's economic and functional grade improved from 2.98 to 3.48 and 2.81 to 3.75, respectively. Conclusion : In overall, the favorable surgical outcome was obtained. This results indicated that with appropriate preoperative selections and indications, careful intraoperative monitoring, and attentive postoperative care, the surgical treatment of eldery patients for the lumbar spinal disorders, significant improvement with acceptable levels of morbidity and mortality can be achived.

Computed tomography (CT) images are widely used for the analysis of the temporal evaluation or monitoring of the progression of a disease. The follow-up examinations of CT scan images of the same patient require a 3D registration technique. In this paper, an automatic and robust registration is proposed for the rigid registration of 3D CT images. The proposed method involves two steps. Firstly, the two CT volumes are aligned based on their principal axes, and then, the alignment from the previous step is refined by the optimization of the similarity score of the image's voxel. Normalized cross correlation (NCC) is used as a similarity metric and a downhill simplex method is employed to find out the optimal score. The performance of the algorithm is evaluated on phantom images and knee synthetic CT images. By the extraction of the initial transformation parameters with principal axis of the binary volumes, the searching space to find out the parameters is reduced in the optimization step. Thus, the overall registration time is algorithmically decreased without the deterioration of the accuracy. The preliminary experimental results of the study demonstrate that the proposed method can be applied to rigid registration problems of real patient images.

This study was conducted to develop the plant-mat for ecological restoration which was formed as the thin multi-layers of woven nets, soil media, seeds, etc. The experimental site was selected at a slope of 240$m^2$ at the rear of Design College of Sangmyung University and divided into 8 sub-experimental plots (20$m^2$ each) according to mat types. (forest-type and grass-type mats with and without seed attachment, respectively) Also, the existing vegetation plot and the no-treatment plot were included in this experiment for comparison. The experiment construction was conducted on September 3, 2002. Mat covered plots regardless of seed attachment showed nearly no signs of erosion even if rainy season in summer compared to the no-treatment plot. Vegetation monitoring result showed that germination rates were somewhat high in both forest and grass-type mats without seed attachment in the initial germination stage. Although germination rates of seed attached mats were somewhat slower than non-seed attached mats in the germination stage, but over time, it showed a good rooting and shooting environment for germinated tree and grass species because of soil media existence within the mat. This indicates that while non seed-attached mats require follow-up maintenance, seed-attached mats does not require maintenance after rooting and germination.

A field survey was performed at the Human-made Wetlands along Boknaecheon of Juam Lake from March 2004 to October 2007 for the purpose of investigating changes of flora for 4 years since its creation. A total of 15 species including 10 families, 13 genera, 12 species and 3 varieties were planted at the Human-made Wetlands along Boknaecheon of Juam Lake which was completed in December 2002. The survey conducted in 2004, 15 months after creation of the Human-made Wetlands, revealed a flora composed of 47 families, 102 genera, 112 species and 19 varieties, 131 taxa in total. In 2007, further increase was registered with 46 species added compared to 2004 reaching 177 species in total. A 4-year monitoring of naturalized plants showed that no quick but constant increase was featured yearly in their number of species with 12 in 2004, 17 in 2005, 18 in 2006 and 19 in 2007. As for changes in life form, 13 species of perennial plants and 2 woody species, 15 in total, were planted initially but, in the survey 2004, 1- or 2-year old therophytes numbered 73, perennial plants 54 and woody species 4, indicating a large change of life form accompanied with increase in overall number of species. The number of 1- or 2-year old therophytes and perennial plants featured a steady increase each year from 2005 to 2007. The distribution ratio of 1- or 2-year old therophytes, however, showed a gradually decreasing tendency while perennial plants tended to increase, instead. As evidenced in changes of flora at the Human-made Wetlands, most of species in it have been determined to be fit or not within 1 to 2 years after its creation and, since the stable settlement of these species onward, its life forms have undergone stepwise changes together with the number of species and individuals in parallel with repeated extinction and penetration of plants.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

Nonketotic hyperglycinemia (NKH) is a rare inborn error of amino acid metabolism. A defect in the glycine cleavage enzyme system results in highly elevated concentrations of glycine in the plasma, urine, cerebrospinal fluid, and brain, resulting in glycine-induced encephalopathy and neuropathy. The prevalence of NKH in Korea is very low, and no reports of surviving patients are available, given the scarcity and poor prognosis of this disease. In the current study, we present a patient with NKH diagnosed on the basis of clinical features, biochemical profiles, and genetic analysis. Magnetic resonance spectroscopy (MRS) allowed the measurement of absolute glycine concentrations in different parts of the brain that showed a significantly increased glycine peak, consolidating the diagnosis of NKH. In additional, serial MRS follow-up showed changes in the glycine/creatinine ratios in different parts of the brain. In conclusion, MRS is an effective, noninvasive diagnostic tool for NKH that can be used to distinguish this disease from other glycine metabolism disorders. It may also be useful for monitoring NKH treatment.
