광역 교통망 및 통신기술의 발전에 따라 광역경제권의 활성화를 위한 협력체계의 중요성이 날로 증대되고 있다. 이에 본 연구는 동남권 광역경제권을 대상으로 GIS 기반의 산업체 정보 공유를 목적으로 동남권 산업체 정보시스템을 구축하였다. 동남권의 경우 제조업 중심의 산업 집적지로서 행정경계를 넘어 산업체간의 근접성과 연결성을 고려한 효율적인 산업 클러스터 및 협력체계 운영이 요구된다. 정보시스템의 DB 구축을 위해 부산, 울산, 경남에서 구축되어진 산업체 DB를 활용하여 정보시스템을 구축한 바, 각 지자체간 데이터의 불일치와 GIS기반의 위치정보 미흡으로 인한 여러 가지 문제점을 발견하였다. 이의 해결을 위해서는 수집 및 배포, 활용과정을 고려한 표준화가 시급한 것으로 분석되었다. 본 연구는 산업체 정보의 공간정보화를 위해 지적도와 수치지도를 활용하여 웹상에서 관리자-사용자 쌍방향간의 정보생성 및 단계별 접근이 가능한 2-way 방식의 산업체 정보시스템을 구축하였다. 본 연구의 결과는 동남권 산업육성을 위한 협력체계 및 공동대응을 위한 산업체 정보 공유체계의 기초적 틀을 제공하였다는 데 그 의의가 있다고 하겠다. Following the technology developments of traffic network and communication for the wide area, the importance of the cooperation system to vitalize the wide area economy is increasing. Therefore, in this study, DongNam Kwon industry information system is established for the industrial information sharing based on GIS in the DongNam Kwon wide area economy. The DongNam Kwon is an industrial integration area centered with the manufacturing so that the operation of effective industrial cluster and cooperation systems are required across the administrational boundaries. To establish the database of the information, the information system was established utilizing already established industrial databases in Busan, Ulsan and Gyeongnam. But, various issues caused by the discordances among the data of each local government and the insufficiency of GIS based location information have been found. According to the analysis, the standardization considering the courses of collection, distributions and utilization are required immediately to solve the issues. This study establishes an 2-way industrial information system enabling the information creation and the phased approach between the administrator and the user in the bi-directions on the web by utilizing cadastral and numerical maps. The result of this study would have a meaning in providing a fundamental frame for cooperative responses and cooperation system for DongNam Kwon``s industrial promotion using industrial information sharing.

Perihepatic capsulitis is associated with various diseases, such as Fitz-Hugh-Curtis syndrome, systemic lupus erythematosus, perforated cholecystitis, perforated hepatic abscess, and tuberculous peritonitis. Miliary tuberculosis is present in about 2% of all reported cases of tuberculosis and is characterized by the widespread millet-like hematogenous dissemination of Mycobacterium tuberculosis. We describe a 24-year-old virgin patient presenting with right upper quadrant and costovertebral angle pain. Diffuse perihepatic capsular enhancement was observed in abdominal computed tomography scans. Chest radiography showed miliary tuberculosis, and a polymerase chain reaction hybridization assay of sputum revealed the presence of M. tuberculosis. Symptoms improved after administering anti-tuberculosis medications. This report describes a rare case of miliary tuberculosis accompanying perihepatitis.

The purpose of this study was to investigate the effects of glucose, sucrose, and glucose polymer(GP) ingestion on the carbohydrate and lipid metabolism during treadmill running in rats. Rats were randomly assigned to normal, control and carbohydrate groups. Carbohydrate group was divided into glucose, sucrose and GP ingested rats. The experiment was carried out after overnight fasting. Rats were administrated either normal saline(control) or carbohydrates solutions of formulated glucose(6%), sucrose(6%) and GP(6%) via polyethlene tube to stomach before treadmill run. Exercise was loaded by a treadmill run at the speed of 1 km/hour for 30, 60 and 120 minutes. The results of experiment were as follows: Plasma glucose levels were decreased in proportion to the exercise time in control, but increased at treadmill run 30 minutes and then gradually decreased with the lapse of the exercise time in carbohydrates compared with normal rats. It decreased in control, glucose, sucrose and GP compared with normal rats in decreasing order at treadmill run 120 minutes(% change of plasma glucose level of control, glucose, sucrose and GP compared with normal rats were 67, 74, 87 and 91 in plasma glucose level at treadmill run 120 min., respectively). Plasma lactate levels were increased by the exercise loading compared with normal in control and carbohydrates ingested rats. It increased in control, sucrose and GP in increasing order compared with normal rats, at treadmill run 120 minutes(% change of plasma lactate level of control, glucose, sucrose and GP compared with normal rats were 167, 185, 149 and 114 in plasma lactate level at treadmill run 120 min., respectively). Plasma FFA levels had tendency to increase by the exercise loading compared with normal in control and carbohydrates ingested rats. It showed increase in the sucrose, glucose, GP and control rats in Increasing order compared with normal rats at treadmill run 120 minutes(% change of plasma FFA level of control, glucose, sucrose and GP compared with normal rats were 151, 153, 166 and 152 in plasma FFA level at treadmill run 120 min., respectively). Plasma acetoacetate levels were higher in control compared with carbohydrates ingested rats at treadmill run 30, 60 and 120 minutes. Plasma beta-hydroxybutyrate levels increased by exercise compared with normal rats in control and carbohydrates ingested rats at treadmill run 30, 60, 120 minutes. Plasma insulin levels were decreased in proportion to the exercise time in control compared with normal rats, but in carbohydrates ingested rats increased at treadmill run 30 minutes and then gradually deceased with the lapse of the exercise time compared with normal. In carbohydrates ingested rats, plasma insulin levies were higher than control. Hematocrit did not show any difference between control and carbohydrates rats at treadmill run 30, 60 and 120 minutes. From these experimental results, it is suggested that the exhaustion of skeletal muscle glycogen, the hypoglycemia, the overproduction of lactate and dehydration is delayed in carbohydrates ingested rats. GP of the carbohydrates is considered as the most effective for these effects. Therefore, intake of carbohydrates before exercise, especially GP seems to increase performance in the prolonged moderate exercise.

This study was carried out to determine the attachment parts and rates on the host fish and the successive stages of the glochidial encystment. A scanning electron microscope observation of the glochidia, the larvae of freshwater brivalve, Anodonta arcaeformis flavotincta, on the host fish, Carassius auratus, was conducted. The attachment rates on the host fish were 30.1%, 22.3% on the pectoral, the caudal, and the pelvic and anal fin, respectively. Glochidia, once attached to the host, have become encysted within 27 hours. The glochidia in fish tissues have sloughed between 13 days and 15 days when the water temperature was 16℃ in laboratory. During encystment, the epithelial cells of the host fish migrated actively toward the attached glochidia and covered them. In the encystment process, the encysted tissues in the host have become loose in seven days and exposured a pat of the glochidium in eight days after infection. No changes of the glochidial size have found before attachment and after sloughing.

Eledctrophysiological phenomena of pyramidal cells in the CAI area of the dorsal hippocampus were recorded from and filled with neurobiotin in anesthetized rats. The electropharmacological properties of membrane as well as the cellular-synaptic generation of rhythmic slow activity (theta)were examined. The intracellular response characteristics of these pyramidal cells were distinctly different from responses of inteneurons. Pyramidal cells had a high resting membrane potential, a low input resistance, and a large amplitude action potential. A afterhyperpolarization was followed a single action potential. Most of pyramidal cells did not display a spontaneous firing. Pyramidal cells displayed weak inward rectification and anodal break excitation. The slope of the frequency-current relation was 53.4 Hz/nA for the first interspike interval and 15.9 Hz/nA for the last intervals, suggesting the presence of spike frequency adaptation. Neurobiotin-filled neurons showed pyramidal morphology. Cells were generally bipolar dendritc processes ramifying in stratum lacunosum-moleculare, radiatum, and oriens. Commissural stimulation discharged pyramidal cells, followed by excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs). The frequency of theat-related membrane potential oscillation was voltage-independent in pyramidal neurons. At strong depolarization levels (less than 30 mV) pyramidal cells emitted sodium spike oscillation, phase-locked to theta. The observations provide direct evidence that theta-related rhythmic hyperpolarization of principal cells is brought by the rhythmically discharging interneurons. Furthermore, the findings in which interneurons were also paced by rhythmic inhibitory postsynaptic potentials during theta suggest that they were periodically hyperpolarized by their GABAergic septal afferents.

This study aimed at analyzing the economic effect of outdoor swimming pool investment using the reservoir's amenity resources. We focused on the identification of the amenity value of reservoir in the rural area and the economic evaluation for establishing infrastructure such as swimming pool based on the reservoir's landscape value. To this end, we have conducted the case study on the outdoor swimming pool in connection with Go-Bok reservoir in Yeon-Gi county, Chungnam Province and estimated its income effect on the rural community by cost-benefit analysis method. The research results are as follows: 1) Outdoor swimming pool participants, with 11,581 visitors totaled to Yeon-gi county every year, was estimated to spend the worth of 58,446 thousand won paid for the agricultural product purchase and etc. 2) Internal rate return of the outdoor swimming pool project was estimated to 16.19%, which considered to be economically feasible comparing with 10% of current capital opportunity cost. Based on the results of this study, we suggest the following strategies for development of amenity value of swimming pool in connected with the reservoir: 1) Reservoir amenities should be well preserved even after construction of swimming pool lest losing amenity values while managing the facilities. 2) Measures to increase the marketing value of intangible reservoir's amenities through promotion should be established. 3) Effective program for more visitors with longer staying and more agricultural products sales should be designed.

권우성,김준수,채진욱,이근미,정승필,문용 영남대학교 의과대학 2003 Yeungnam University Journal of Medicine Vol.20 No.1

정상체중을 가진 성인 남성에서 지방과다(adiposity)와 심혈관계 질환의 위험요인과의 관련성을 알아보고자 하였다. 2001년 1월 3일부터 12월 31일까지 영남대 학교의료원에서 종합검진을 받은 만 28∼69세 성인 남성 129명을 대상으로 연령, 신체계측, 혈압, 공복 혈당, 혈청 지질대사치와 체성분 검사를 실시하였다. 체질량지수(BMI)가 18.5∼23 kg/㎡(76명)인 정상체중군과 23∼25 kg/㎡(53명)인 과체중군으로 분류하고, 체비방률, 체지방량과 위험인자들(수축기혈압, 이완기혈압, 공복시 혈당, 중성지방, 저밀도지단백, 고밀도지단백)의 상관관계를 분석하고, 정상체중군을 지방과다에 따라 3군으로 나누고, 각 군과 과체중군에서 심혈과 질환의 위험인자를 평가하였다. 정상체중의 제1군을 기준으로 제2, 3군과 과체중군의 위험인자 존재에 대한 비차비(odds ratio)를 조사하였다. 정상체중군에서 지방과다 변수들(adiposity variables: 체지방량, 체지방률)과 수축기 및 이완기 혈압, 저밀도지단백, 중성지방에서 유의한 상관관계가 있었다. (P<0.01). 나이를 보정하고 난 뒤 제1군을 기준으로 제3군(체지방율: 3.7, 체지방양: 4.7)과 과체중군(체지방율: 6.6, 체지방양 11.5)에서 위험인자에 대해 더 높은 비차비를 가졌다. 지방이 많은 정상체중의 성인남성은 적은 지방을 가진 성인 남성보다 심혈관 질환에서 더 높은 유병 위험도를 가졌다. 지방 측정은 정상체중군에서 심혈관계 질환의 위험인자외에 추가적인 정보를 제공할 수 있었다. Background: Most of all studies about the relation between the health risk and obesity are based on the European and American data. The purpose of this study is to examine the relation between adiposity and factors for cardio vacular disease (CVD) in normal weight individuals. Materials and Methods: Normal weight subjects with a body mass index (BMI) between 18.5 and 23 kg/㎡(76 subjects) and overweight subjects with a BMI between 23 and 25 kg/㎡ (53 subjects) were retained for this study. Normal weight subjects were divided into three group of each adiposity variable, then three group and the overweight group were evaluated for the presence of CVD risk factors and analyze the correlation coefficients between adiposity variables and risk factors controlled for age in normal weight, overweight groups. Using logistic regression analysis, the odds ratio (OR) for the prevalence of risk factors for each group of adiposity variables and the overweight group was estimated relative to the first group in normal weight subjects. Results: Systolic BP, diastolic BP, LDL cholestrol, HDL cholesterol, triglycerides in normal weight subjects were significantly correlated with all adiposity variables (P<0.01). Third group (3.7 for %fat and 4.7 for fat mass) of adiposity variables in the normal weight group and the overweight group (6.6 for %fat and 11.5 for fat mass) tended to have higher ORs compared to first group for risk factor variables. Conclusion: Normal weight subjects with elevated adiposity had higher prevalence of risk factors than normal weights subjects with less adiposity. Measuring of adiposity added additional information of cardiovascular disease risk factors in normal weight subjects.
