21세기에 들어 在來木本植物을 이용한 비탈면 綠化가 이용되기 시작되고 있으므로 그 발전방향을 예측하기 위해 綠化의 기본적인 개념과 綠化에 대한 주역주민의 인식을 정리하여 보았다. 조사결과, 지역주민은 綠化의 필요성과 在來木本植物을 이용한 工法을 충분히 인식하고 있었으나, 外來種의 도입에 대해서는 대부분의 주민이 부정적이었다. 따라서 앞으로는 비탈면 綠化의 多面性을 추구해야 하며, 在來 木本植物의 도입이 곤란한 장소에는 在來 雜草類의 이용을 추진해야 할 것이다. 또한 비탈면에 시공하고 있는 金網은 人爲的 災害를 유인할 가능성이 있으므로 시정할 필요가 있다. 결론적으로 비탈면 綠化는 단기적으로는 비탈면의 物理的 安定과 生態的 安定에, 중·장기적으로는 地球環境의 改善과 向上에 기여해야 할 것이다. The twenty-first century was entered and began to show the extent where revegetation of the face of slopes using the native woody plant was nationwide at last. Then, future revegetation of the face of slopes was considered on the basis of them in order to attempt the development of this direction, while the recognition for fundamental matter of the revegetation and revegetation of t h e regional inhabitant was arranged this time. The regional inhabitant sufficiently understood t h e necessity of the revegetation, and the method using the native woody plant had sufficiently been recognized, and the high evaluation was given in the method. In the other, the major inhabitant questioned it for introducing the exotic species. I t was proposed that the utilization of native weeds should be advanced by the pursuit of many facets of the revegetation of the face of the slopes based on these in future in the place where the introduction of the native woody plant is difficult. And, the method for stretching the wire netting for the face of slopes indicated the necessity of the urgent review, because the artificial disaster might be caused. As a conclusion, the goal of the revegetation of the face of slopes confirmed that it was ecologically stable short-terminable face of slopes physically and connects it with the medium and long term for improvement and improvement of global environment, and it indicated the importance of the revegetation of the face of slopes.

The purpose of this study was to analyze the effect of walking exercise on health-related physical fitness and Subcutaneous fat thickness in obese middle-aged women. SPSS 11.0 was used to calculate mean and SD, and ANCOVA was conducted to examine the group difference between paired sample t-test and pre-test and post-test. The level of significance was set at a=.05. 1. The change of health-related physical fitness was examined, In the EG, there was no statistically significant difference in muscular strength, but there was statistically significant difference in muscle endurance(p<.05), f1exibi1ity(p<.01), and cardivascular endurance(p<.OOl). In the CG, there was no statistically significant difference in all factors. 2. The change of body composition was examined. In the EG, there was statistically significant difference in weight(p<.001) and % body fat(p(.001), but 3. The change of skinfold thickness was examined. In the EG. there was statistically significant difference in triceps. subscapular, midaxillary, abdominal, suprailliac, and popliteal muscles(p<.001) and front thigh(p(.01), but there was no statistically significant difference in medial calf. In the CG, there was no statistically significant difference in all regions. In conclusion, as results of conducting the 12-week walking exercise program for obese middle-aged women, it was found that the program improved health-related and effectively reduced % body fat and skinfold thickness. It is recommended that middle-aged women should do low intensity endurance exercise rather than excessive exercise. Further study should conduct a walking exercise program and a dietary cure together to provide obese middle-aged women with a more effective program.

This study was conducted to have basic and applied informations to establish the cultivation method and to improve the cultivation techniques of Angelica gigas Nakai through investigating the rates of germination and seedling establishment with treatment of plant growth regulator and seed priming. The germination rates of round shape seed were about 0.3~12% higher than those of parallel shape. The germination rates with different storage durations were increased at the level of 25oC and 4oC with the storage days, while they were clearly higher at -20oC compared to those at 4oC and 25oC without the storage durations. With the results of germination rates with treating of plant growth regulator and seed priming, their rates with the round shape seeds were comparatively higher about 6% than those with parallel shape seed and they were increased with increasing of the storage durations. The germination rates were generally appeared higher with GA3 than did those with seed priming. The highest germination rate was appeared at 50 ppm GA3 of plant growth regulator and at -0.5 MPa PEG6000 of seed priming. The germination rates?ㅤ ?ㅤ of Angelica gigas were different with different temperature, storage durations and the treatments of plant growth regulator and seed priming. These results could be used according to different cultivating conditions.

觀光을 通한 地域活性化에 關한 硏究 : 日本의 內發的 地域活性化의 事例를 中心으로

田元培,權晶澤 大邱大學校 社會科學硏究所 1999 社會科學硏究 Vol.6 No.1

地域의 觀光開發 事業이 活性化되고 관광개발이 地域發展에 미치는 效果를 極大化 하기 위해서는 관광개발에 대한 發想의 轉換이 절실히 요구된다. 換言하여 금후 觀光의 觀光政策은 地方化時代의 定着과 觀光産業의 環境變化 등을 고려할 때 中央政府 차원에 의한 위로부터의 관광개발이 아니라 地域에 基盤을 두고 地域社會와의 連繫 속에서 이루어지는 地域觀光, 즉 地域性을 확보하는 방향으로 槪念轉換이 이루어져야한다. 이를 위해 地域文化 및 主體性의 再發見, 地域特性의 觀光資源化를 적극적으로 추진해야하며 觀光關聯事業에 內發的인 住民의 參與를 誘導하기 위한 方案을 摸索해야 한다. 內發的인 地域活性化는 外部에 대해 地域이미지의 提高와 地域의 自玲心과 愛鄕心을 鼓吹시키고, 나아가 觀光客의 지역에 대한 訪問動機를 자극시켜 방문을 유도하고, 窮極的으로는 地域住民의 삶의 質 向上에 기여한다. 그러나 地方自治制의 역사가 일천하고 觀光의 地域活性化에 대한 效果가 經濟的 效用에 지나치게 중점을 둔 나머지, 관광을 통한 지역의 意識啓發과 文化生活空間을 제공하며 地域住民의 福利增進이라는 面에서는 소홀하게 취급되어왔던 게 사실이다. 지역활성화를 위한 전통적인 전략을 기본적으로 外來型 開發, 즉 外部의 支援에 의한 대규모 개발 사업을 통한 地域開發의 추구였다. 이와 같은 전략 하에서는 國家 政府의 역할이 가장 중시된다. 그러나 최근 世界化, 情報化로 國境, 距離의 개념이 약화되고 경제성장요소의 移動이 보다 다이나믹해 감에 따라 地方化를 더욱 촉진 시키게되고 이러한 환경 하에서 中央政府 主導方式의 地域開發은 그 실효성을 더욱 저하시킬 수밖에 없는 것으로 평가된다. 따라서 전통적 戰略의 代案으로 주목받게 된 이론이 곧 內發的開發이다. 內發的開發은 地域內部의 모든 자원 - 자연적, 인적, 기술적, 문화적, 조직 및 제도적 자 원-을 活用, 이들간의 相互作用을 活性化시키고 統合함으로써 地域力量(regional capacity) 을 極大化시키는 戰略이다. 여기에서 지역의 인적, 조직 및 제도적 자원은 지역개발의 主 體가 되는 資源이고 자연적, 기술적, 문화적 자원은 지역개발의 客體的 資源이 된다.

최근 다약제 내성균주의 출현과 후천성 면역결핍증으로 인한 결핵발병률의 증가는 전세계적으로 중요한 보건문제가 되었다. 따라서 보다 빠르고 신뢰할 만한 진단법은 결핵박멸을 위한 가장 중요한 필요조건 중의 하나일 것이다. 본 연구는 171명의 환자를 대상으로 폐결핵 진단의 전통적 방법들 (X-선,항산성 염색,배양)과 PCR법간의 진단적 가치와 효율성을 비교 검토하기 위해 시행하였다. 흉부 X-선 소견 및 검사 결과 그리고 다른 임상 소견들을 통해 결핵으로 확진된 예는 전체 171건의 검체 중 39예 (22.8%)였다. 이러한 확진을 근거로 할 때 각 검사별 민감도, 특이도, 효율성, 위양성률, 위음성률을 살펴 보면 흉부 X-선의 경우 각각 69.2%, 87.1%, 83.0%, 12.9%, 30.8%; 항산성 염색의 경우 79.9%, 95.5%, 91.8%, 4.6%, 20.5%; 배양의 경우 56.4%, 99.2%, 89.5%, 0.8%, 43.6%; PCR의 경우 82.1%, 96.2%, 93.0%, 3.8%, 17.9%였다. PCR의 경우 가장 높은 민감도 및 효율성과 가장 낮은 위음성률을 보였다. 배양법은 가장 높은 특이도와 가장 낮은 위양성률을 보였다. 결론적으로 PCR은 결핵 진단을 위한 신속하고 효율적인 우수한 검사 방법이므로 일상적 임상 검사로의 활용가치가 매우 높다고 하겠다. 그러나 전통적인 여러 방법들 역시 임상상황에 따라 그 나름대로의 특별한 가치를 지니고 있으므로 철저한 정도관리를 통해 PCR과 병행한다면 결핵균 검출율을 보다 높일 수 있으리라 판단된다. In recent years continuously increasing number of tuberculosis (TB) cases due to the emergence of strains with multidrug resistance and AIDS is a significant global health problem. Therefore, more rapid and reliable diagnosis of TB may be one of the most urgent needs in efforts to eradicate the disease. The present study was designed to compare and assess the diagnostic values and efficiencies between the conventional methods (X-ray, AFB stain and culture) and PCR for pulmonary TB on 171 cases. Chest X-ray finding and clinical features revealed that 39 (22.8%) of 171 sputum specimens were pulmonary TB cases. The statistical data were taken on the basis of the definitive diagnosis: In X-ray, overall sensitivity, specificity, efficiency and false positive and false negative incidence was respectively 69.2%, 87.1%, 83.0%, 12.9%, and 30.8%; 79.5%, 95.5%, 91.8%, 4.6% and 20.5% in AFB-stain; 56.4%, 99.2%, 89.5%, 0.8% and 43.6% in culture; 82.1%, 96.2%, 93.0%, 3.8% and 17.9% in PCR. PCR got a highest sensitivity and efficiency as well as a lowest false negative incidence. Culture had a highest specificity with a lowest false positive incidence. These results imply that PCR assay is fast, sensitive and efficient method for diagnosis of pulmonary TB. However, combined use of the conventional methods wish thorough quality control may offer more opportunities for detecting Mycobacterium tuberculosis and diagnosting TB although they have some limits.

제2형 당뇨병 환자에서 비만 지수와 죽상경화증 위험인자들과의 상관성

정병천,박순홍,이주영,이신원,정성창,김정국,하승우,김보완 대한비만학회 2003 The Korean journal of obesity Vol.12 No.2

연구배경: 비만은 제2형 당뇨병의 중요한 병인이면서 죽상경화성 동맥질환의 위험인자인 인슐린 저항성, 지질대사 이상 및 고혈압의 원인으로도 인정되고 있다. 한편 비만에 의한 대사성 및 혈관 합병증은전신적 지방량의 증가보다 복강내 지방축적이 병인적 중요성을 가지고 있다고 한다 그러나 국내의 제2형 당뇨병 환자를 차상으로 비만과 이들 죽상경화증 위험인자와의 상관관계를 연구 조사한 성적은 많지않다. 이에 제2형 당뇨병 환자에서 전신적 비만과 복강내 지방 축적을 반영하는 각각의 신체계측지수들과 죽상경화증 위험인자와의 상관성을 검토함으로써 국내 제2형 당뇨병 환자의 비만도가 대사성 및 혈관성 합병증에 미치는 영향과 신체계측지수들의 임상적 가치를 평가하고자 하였다. 방법 : 제2형 당뇨병 환자 425명 (남자 196명, 여자 229명)을 차상으로 하였다 임상적 단백뇨가 있거나 인슐린 치료, 혈압강하제 또는 지질대사개선제를 복용하는 환자는 제외시켰다. 전신 비만은 체용적지수 그리고 피부두겹 두께로 산출한 체지방률을, 복강내 지방축적도는 허리둘레 및 요둔위비를 이용하였다. 죽상경화증의 위험인자로는 혈당 조절 정도를 나타내는 공복 혈당과 당화혈색소 농도, 인슐린 저항성을 나타내는 공복 인슐린 및 C-peptide 농도, 지질 대사 상태를 나타내는 총 콜레스테롤, 중성지방, 고밀도지단백 콜레스테롤 및 저밀도지단백 콜레스테롤 농도 그리고 수축기 및 이완기 혈압을 선택하였다. 전신 비만지수 및 복부 비만지수와 이들 위험인자와의 상관관계는 연령과 당뇨병 이환기간을 보정하고 편상관분석법을 사용하였다. 결과: 1 여성군에서 남성군에 비해 체용적지수(24.2 대 23.0kg/㎡, p<0.01) 및 체지방률(23.8 대13.5%, p<0.01)은 다소 높았으나 허리둘레 (87.0 대 85.8 cm)와 요둔위비 (0.96 대 0.96)는 차이가 없었다. 2. 인슐린 저항성을 반영하는 공복 인슐린 및 C-peptide 농도는 체용적지수. 체지방률, 허리둘레 및 요둔위비가 커질수록 증가하는 양의 상관관계를 보였다(상관차수 0.21∼0.42, 모두 p<0.05). 3. 혈청 지질중에는 고밀도지단백 콜레스테롤만이 남성 환자군에서 비만지수들과 약한 음의 상관성을 보이는 경향이었고, 총 콜레스테롤 및 중성지방농도는 상관성이 없었다. 4. 수축기 및 이완기 혈압은 남성군에서만 체용적지수. 체지방률, 허리둘레 및 요둔위비가 커질수록 상승하는 양의 상관관계를 보였다(상관차수 0.21∼0.33, 모두 p.0.05). 결론. 국내 제2형 당뇨병 환자들의 전신 비만도 및 복부 비만도가 서구인에 비해 심하지는 않으나 포도당 대사, 인슐린 저항성, 지질 대사 및 고혈압에 위해한 영향을 미칠 수 있는 수준에 이르고 있으며 이는 결국 죽상경화증의 위험인자로도 작용하게 될 것임을 시사한다고 하겠다. 그리고 신체계측을 통한전신 비만 및 복부 비만 지수 모두가 당뇨병 및 죽상경화증의 위험을 간접적으로 예견하는 유용한 척도가 될 수 있을 것이다. Background: Obesity is the powerful risk factor for type 2 diabetes and also associated with a significantly increased risk of insulin resistance, dyslipidemia, hypertension and atherosclerosis. Although obese individuals have these diseases, the relationship between obesity and these diseases was not certain until regional fat distribution was taken into account. Reports about the relationship between obesity and the risk factors of atherosclerosis in type 2 diabetics in Korea are very rare. To evaluate the relative importance of anthropometric indices on the development of atherosclerosis and obesity-related metabolic and vascular complications, the correlations of these indices with the risk factors for atherosclerosis were studied. Methods: Patients with type 2 diabetes mellitus (n=425, male 196, female 229) who not used antihy- pertensives or anti-lipidemic agents were investigated. Body mass index (BMI) and percentage of body fat (%BF) estimated by skinfold-thickness in assessing generalized adiposity, and waist circumference (Wc) and waist-to-hip ratio (WHR) in assessing visceral adiposity were taken as anthropometric indices. We included the indicators of glycemic control (fasting blood sugar and HbAlc), insulin resistance (fasting serum insulin and C-peptide concentrations), lipid abnormalities (serum total cholesterol, triglyceride, HDL-cholesterol, and LDL-cholesterol concentrations), and systolic and diastolic blood pressure as risk factors for the development of atherosclerosis. Partial correlations of the anthropometric indices with those risk factors were investigated with adjustment of age and duration of illness. Results: 1. BMI and %BF in female patients group were higher than those in male (24.2 vs 23.0 kg/㎡, 23.8 vs 13.5%, respectively, p<0.01 in all) although Wc and WHR were similar between both groups. In general, both body adiposity and abdominal obesity in them were much lower than in the Western. 2. Serum insulin and C-peptide levels were positively correlated with BMI, %BF, Wc and WHR (r=0.21~42, p<0.05 in all). 3. Serum total cholesterol, triglyceride and LDL- cholesterol were not correlated with any anthropometric indices. A weak negative correlation of serum HDL-cholesterol with these indices was found in male patients group. 4. Both systolic and diastolic blood pressures were positively correlated with all these indices only in male group (r=0.21~33, p<0.05 in all). Conclusion: These results suggested that the severity of both generalized and visceral adiposity in these patients with type 2 diabetes mellitus were only mild but adiposity with abdominal distribution of body fat in diabetes mellitus could be a significant risk factor of developing atherosclerosis. In clinical practice, these anthropometric indices indicating general adiposity and abdominal obesity may provide useful information for predicting disease risks, especially of diabetes and cardio- vascular disease indirectly.

Asphalt로 피복된 Portland Cement를 使用한 Concrete의 諸性質

尹錫天,李昌甲,洪元杓,鄭秀永,南宰鉉 충남대학교 공업교육연구소 1982 論文集 Vol.5 No.1

The construction works with concrete has the potential problems of water tightness. The conventional treatments for water-tight concrete are not satisfactory in terms of strength and water tightness. This study was to investigate the effects and application of the asphalt-coated portland cement on water-proof of the concrete and its influences on the physical properties of the concrete. The asphalt-coated portland cement, which is hereafter referred to as ACPC, was made by coating ordinary portland cement with asphalt in the rate of weight ranging from 0.5 to 1.0 percent. In this process, Calcium Chloride and Sodium Silicate were tried as the hardening time accelerator for producing ACPC, and carbon black, talc and other materials were tested for their effectiveness as pore filler. The specimens were prepared and tested with the various amounts of additives as a variable factor to find the optimum material. The analysis was mainly focused at water tightness, physical properties of the concrete and working conditions. The major findings of this experiment are as follows ; 1) Water-proof Test ① The specimens of ACPC and ordinary portland cement(OPC) were tested under the pressures of 3 and 9 kilograms per square centimeter per 24hours respectively and compared. The OPC specimens showed considerable amount of leakaged water while the ACPC specimens were rated lower permeabilities of 89%/28days, 40%/56days and21%/84days under the abovementioned pressure conditions. The most successful composition for water-proof was identified as ACPC added with Calcium Chloride and carbon black. ② The ACPC demonstrated its superiority in absorption test. The absorption amount of OPC for l hour was greater than that of ACPC for 24hours. 2) Compressive Strength Test Four kinds of specimens of ACPC aging 7, 28, 56 and 84days were tested and compared for their respective results of OPC. The ACPC added with carbon black was lower than OPC in compressive strength in the case of curing ages of 7 and 28days but ACPC was superior to the OPC in the specimens aging 56 and 84days. The ACPC added with others except carbon black exposed their lower compressive strength in all circumstances compared with the OPC specimens. 3) Slump Test The slump of ACPC with various additives such as carbon black, talc or clay was 21.6 centimeter which was higher than the OPC of 18.4centimeter slump. This result concluded that ACPC was much favorable in workability in comparison with that of the OPC. The conclusions are summarized as follows; 1) The optimum mixture for water tightness and compressive strength of concrete was found at 0.5% of SACPC, Calcium Chloride and carbon black respectively at the rate of the weight of cement.
