본 연구는 지리산국립공원 심원계곡 생태경관 복원공사지역의 모니터링 결과를 분석하여 체계적인 복원관리를 도모할 수 있는 기초자료를 확보하는데 그 목적이 있다. 복원사업이 완료된 2017년도에 식생 모니터링을 위한 조사구 12개소와 대조구 4개소를 설치하였고, 2017년과 2020년의 상대우점치, 종다양도지수, 유사도 등의 변화를 분석하였다. 복원사업 시 수목이 식재되었던 조사구는 종다양도지수가 0∼1.4552로 나타났고, 대조구와의 유사도지수에서는 1개 조사구가 1.32%로 분석된 것을 제외하고 모두 0%로 나타났다. 조사구의 종다양도지수 및 유사도지수가 매우 낮은 것은 복원사업 시 식재된 수목이 고사하거나 멧돼지 피해, 유수에 의한 침식으로 유실되는 등의 영향으로 판단되었다. 반면 복원사업 시 수목이 식재되지 않은 미식재 조사구는 종다양도지수가 0.9538∼2.3222로 나타났고, 유사도지수는 최대 8.33%까지 분석되었다. 국립공원 생태경관 복원공사지역의 복원 공법 개발을 위한 장기 모니터링과, 미식재 조사구의 천이과정을 분석하는 지속적인 연구가 필요하다. This study aims to obtain basic data for systematic restoration by analyzing the monitoring results of the Shimwon Valley Ecological Landscape Restoration Project area in Jirisan National Park. In 2017, when the restoration project was completed, 12 monitoring plots and 4 control plots were installed for vegetation monitoring, and changes in the relative dominance, species diversity index and similarity between 2017 and 2020 were analyzed. The species diversity index of the surveyed areas where trees were planted during the restoration project was 0-1.4552, and the similarity index with the control group was 0% except for one survey area at 1.32%. The very low species diversity index and similarity index in the survey areas were attributed to the loss of trees planted during the restoration project due to death, damage by wild boars, or erosion by running water. On the other hand, the species diversity index was 0.9538-2.3222 in the monitoring plot where no tree was planted, and the similarity index was analyzed to be as high as 8.33%. It is necessary to continue the long-term monitoring for the development of ecological landscape restoration methods in the national park and analysis of the succession in monitoring plots where no trees were planted.

Second, the contact and the commitment variables were the most influential variables on the participation of the juvenile sport activity.

共同住宅 單位世帶의 Life Cycle Cost 最適化 方法論 硏究

박태근 牧園大學校 建築·都市硏究센터 1993 建築·都市環境硏究 Vol.1 No.-

Recently, because energy and labor costs for maintenance have increased rapidly in apartment buildings, it was most important to consider those costs during the design stage. And because the same walls and windows are repeatedly used through out the whole apartment building, the LCC optimization of unit plan is very important in the LCC minimization of the building itself, And then the items that are varied with a change of apartment systems are studied, the optimum size calculation technique of unit plan is studied.

Demand-Driven Dataflow 컴퓨터 시스템의 설계

박규태,이상범,류근호 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

Dataflow computers exhibit a high degree of parallelism which cannot be exploited in a conventional von-Neumann architecture framework. Among the well-established dataflow computers is an MIT machine, whose driving force is heavily based upon data-driven computation. This paper describes a new dataflow machine which further improves the relatively poor performance exhibited by the MIT machine. Our machine is designed by adding the notion of demand-driven computation to the MIT machine structure.

p-(p'-Hydroxy phenylazo)-benzoic의 합성과 LB막 특성에 관한 연구

박태곤,송경호,박근호 國立 昌原大學校 産業技術硏究所 1993 産技硏論文集 Vol.7 No.-

The Synthesis of p-(p'- Hdroxyl phenly azo)- benzoic acid was studied to get optimized conditions. The spectrum of the product of reaction containing azobenzene chromophores was investigated by using ultraviolet spectrophotometery in acetone solvent at room temperature. In addition, UV absorption spectra of langmmuir Blodggett film deposited on quartz plate was measured, and the structure of these compounds were ascertained by measuring the ultraviolet and infrared spectra. Recrystallization of reaction product in the solvent( water:methanlo:acetone) atmosphere results 68% p-(p'- Hdroxyl phenly azo)-benzoic acid yield and the melting point of that was about 254-267°C (decomposition). The LB film of azobenzene derivatives with long alkyl chains shows some possibility to be applied to functional molecular devices such as photomemory and lignt switching

This study makes an object high school students (200 males, 200 females) who are active and sensitive to fashion to reveal the influence of the teenage consumer' attitude by the brand image of a sports products. The study conclusion is as follows. First, sports shoes(3.567), sports clothes(3.527), sports beverages(3.058)and sports outfits(3.527) are displayed in order of their interests. Second, the brand image of a sports product is a variable which has high relation to their awareness and preference and there is affirmative relation between the image and their attitude. Third, sex has nothing to do with thier awareness and preference. Fourth, their self-involvement has nothing to do with their awareness and preference, either.

박태근,김석규,김승환 동아대학교 건설기술연구소 2000 硏究報告 Vol.24 No.1

The purpose of this study is to investigate the status of street trees planted on main roads in Kimhae city. The species of street trees in Kimhae city are nine, it is not various. As the planting ratio of Ginkgo biloba, Prunus yedoensis, Zelkova serrata, Prunus sargentii is 86%, it is finded that street trees are concentrated on some species of trees. The planting ratio of deciduous tree in Kimhae city is 95.8%. Therefore it needs to increase a planting ratio of evergreen tree.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.
