The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.

편도중심핵의 dopamine성 체계가 스트레스성 위궤양에 미치는 영향

장현갑,윤병수,박순권 한국심리학회 한국심리학회지 생물 및 생리 Vol.4 No.1

본 연구는 스트레스성 위궤양발생과 편도중심핵의 dopamine(DA)와의 관계를 알아보기 위해 두가지 실험을 실시했다. 실험1에서는 DA성 신경원을 손상시키는 6-OHDA를 편도중심핵에 주입하여 DA성 신경원을 손상시킨후 저온-구금스트레스에 의한 스트레스성 위궤양발생정도를 비교하였고, 실험2에서는 DA효능물질인 apomorphine과 DA길항물질인 haloperidol을 편도중심핵에 주입한 후 저온-구금스트레스에 의한 위궤양발생정도를 비교하였다. 실험1의 결과에서는 6-OHDA처치에 의한 편도체 중심핵 손상집단이 saline통제집단 보다 유의미하게 높은 위궤양발생을 보여주었고, 실험2에서는 DA효능물질인 apomorphine처치집단이 saline통제집단보다 유의미하게 낮은 수준의 위궤양발생을 보여주었지만, DA수용기 차단물질인 haloperidol처치집단은 saline통제집단과 apomorphine처치집단에 비해 유의미하게 높은 위궤양발생을 보여주었다. 위의 두실험의 결과로 미루어 볼때 편도중심핵의 DA성 신경원과 여기에서 분비하는 DA가 스트레스성 위궤양발생에 중요한 역할을 하는 것으로 추측할 수 있다. To investigate the effects of central amygdala dopamine on immobilization stress-induced gastric ulcer in rats, two experiments were conducted. In experiment 1, 6-OHDA(10㎍) was injected bilaterally into central amygdala to destroy dopaminergic neurons. On 7 days after drug treatment the rats were immobilized individually in supine-restraint devicers at 4℃ for 3hrs. The results of experiment 1 were as follows: lesion of dopaminergic neurons in central amygdala aggravated the gastric ulcer induced by stress. In experimemt 2, apomorphine(10㎍), haloperidol(10㎍) and saline were injected bilaterally into central amygdala. At 30min after drug treatment the rats were restrainted at 4℃ for 3hr. The results were as follows: apormophin had an attenuating effect on the gastric ulcers, but haloperidol had an aggravating effect. These results indicate that dopaminergic neurons and dopamine of central amygdala does play an important role in the stress-induced gastric ulcer.

金炳洙,朴鉉圭 慶北大學校 1986 論文集 Vol.42 No.-

In order to use as genetic or breeding material, 8 land cultivars of pepper ('Daehwacho', 'Subicho' and 'Chilsungcho' in Youngyang-Gun, 'Jangrimcho' and 'Kalmicho' in Uesung-Gun, 'Kimyongcho' in Munkyung-Gun, 'Punggakcho' in Cheongdo-Gun, and 'Jinancho' in Cheongson-Gun) were collected and their fruit characters were measured. 'Daehwacho' was thick at the shoulder of fruit and was conical with long pedicel. 'Subicho' was elongate and mild with much sweet taste and unique aroma. 'Chilsungcho' was thick at the waist of fruit with a think pericarp. 'Jangrimcho' was slender in fruit shape, and was medium-sized. 'Kimyongcho' was small-fruited and hot. Fruits were hard with many seeds. 'Kalmicho' was thick at the shoulder of fruit but tapering to form a slim pointed tail and was very hot. 'Punggakcho' was somewhat irregular in shape, mild and sweet, and thick-walled. 'Jinancho' was a small fruit cultivar.

김현수,박주량,이승무 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

This investigation was carried out to study the dynamic characteristics of the removal of Cu(II) from wastewater by the technique of foam fractionation, using sodium-dodecylbenzenesulfornate (DBS) as a foaming agent. The surface excess concentration of Cu(II) with the change of DBS concentration in feed solution and superficial gas velocity was obtained by measuring foam diameter. The value of HTU with the change of DBS concentration and superficial gas velocity was determing by measuring superficial liquid velocity. The experimental results are obtained as follows: 1. When Cu(II) concentration in feed solution is constant, the surface excess concentration of Cu(II) increased as DBS concentration increased. But decreased as superficial gas velocity increased. 2. Equilibrium constant (Tcu/Cw) between the surface excess concentration of foam and the concentration of interstitial liquid increased as DBS concentration in feed solution increased. However it was not affected by the change of superficial gas velocity. 3. For the superficial gas velocity above 10cm/min, the empirical equation was derived as follows: HTU = 2 exp [0.642(??) - 0.19(??)] where, C??(DBS) denotes the DBS concentration in feed solution, and v is the superficial gas velocity.

김현수,이승무,박진원 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

This study was carried out to study the efficiency of the induced aerator which causes nearly complete mixing and high oxygen-transfer in the aerator. With varying rpm, the oxygen-transfer coefficient was determined. The removal efficiency of substrate was measured analytically by varying feed concentration, feed flow rate, and rpm at constant biomass recycle ratio. The experimental results show that the oxygen-transfer coefficient varies linearly with rpm, and the optimum rpm is 3000. By expressing the specific substrate utilization rate constant, K with regard to rpm, the rate constant, K was investigated with varying dilution rate. The DO concentration, the removal of COD and BOD?, and the effect of MLSS in the aerator was also investigated with varying rpm.

본 연구는 충남도립공원(덕산도립공원, 칠갑산도립공원, 대둔산도립공원)에 분포하고 있는 산림 식생을 비교 분석하기 위해 2006년부터 2016년까지 실시되었다. 본 연구 조사지의 식생을 식물사회학적 방법으로 분석한 결과, 덕산도립공원은 신갈나무군락, 소나무군락, 굴참나무군락 및 느티나무군락으로 구분되었고, 칠갑산도립공원은 굴참나무군락, 신갈나무군락, 소나무군락 및 서어나무군락으로 구분되었으며, 대둔산도립공원은 신갈나무군락, 굴참나무군락 졸참나무군락, 개서어나무군락, 서어나무군락, 소나무군락 및 상수리나무군락으로 구분되었다. 각 도립공원의 중요치는 덕산도 립공원에서 신갈나무가 가장 높았으며(72.35), 다음으로 소나무(70.25), 굴참나무(53.11), 때죽나무(11.44), 산벚나무(11.17), 물푸레나무(10.41) 등의 순으로 나타났으며, 칠갑산도립공원에서는 굴참나무가(73.34) 가장 높았고 다음으로 소나무(58.71), 신갈나무(57.02), 서어나무(18.84), 졸참나무(13.48), 산벚나무(13.31) 등의 순으로 나타났다. 대둔산도 립공원은 신갈나무가(57.03) 가장 높았고 다음으로 굴참나무(31.98), 졸참나무(31.53), 소나무(16.80), 개서어나무(16.50), 서어나무(16.07), 쪽동백나무(15.76), 당단풍나무(10.09) 등의 순으로 나타났다. 중요치가 높은 주요 분류군에 대한 흉고직경급을 분석한 결과 덕산도립공원에서는 신갈나무, 굴참나무가 정규분포형의 밀도를 나타내고 있어 당분간은 이들 수종의 우점 상태가 계속될 것으로 보인다. 칠갑산도립공원에서는 굴참나무, 신갈나무, 소나무가 정규분포형의 밀도를 나타내고 있어 당분간은 이들 수종의 우점 상태가 계속될 것으로 보이나 서어나무와, 졸참나무의 어린 개체 밀도가 높아 앞으로 이들의 세력이 확장될 것으로 판단된다. 대둔산도립공원은 신갈나무와 굴참나무는 어린개체의 밀도가 높은 역 J자형을 하고 있어 우점 상태가 계속될 것으로 보이며, 개서어나무와 소나무는 어린 개체와 큰 개체의 밀도가 낮고, 중간 개체의 밀도가 높아 정규분포형의 밀도를 나타내고 있는 것으로 보아 당분간은 이들 수종에 의한 우점 상태가 계속될 것으로 판단된다. 서어나무와 졸참나무는 중간이상의 개체와 비교해 볼 때 어린 개체의 밀도가 높아 앞으로 이들의 우점도가 증가할 것으로 예상된다. This study compared forest vegetation in Chungcheongnam-do Provincial Park (Deogsan, Chilgabsan, and Daedunsan) from 2006 to 2016. The results of the analysis on the vegetation of the research sites by the phytosociological method showed that the Deogsan Provincial Park had Quercus mongolica community, Pinus densiflora community, Q. variabilis community, and Zelkova serrata community. Chilgabsan Provincial Park had Q. variabilis community, Q. mongolica community, P. densiflora community, and Carpinus laxiflora community. Daedunsan Provincial Park had Q. mongolica community, Q. variabilis community, Q. serrata community, C. tschonoskii community, C. laxiflora community, P. densiflora community, and Q. acutissima community. The importance value in each Provincial Parks was analyzed as follows. The importance value of Q. mongolica(72.35) was the highest in Deogsan Provincial Park, and followed by P. densiflora(70.25), Q. variabilis(53.11), Styrax japonicus(11.44), Prunus sargentii(11.17), and Fraxinus rhynchophylla(10.41). Q. variabilis(73.34) was the highest in Chilgabsan Provincial Park and followed by, P. densiflora(58.71), Q. mongolica(57.02), C. laxiflora(18.84), Q. serrata(13.48), and Prunus sargentii(13.31). The importance value of Q. mongolica(57.03) was the highest in Daedunsan Provincial Park and followed by Q. variabilis(31.98), Q. serrata(31.53), P. densiflora(16.80), C. tschonoskii(16.50), C. laxiflora(16.07), S. obassia(15.76), and Acer pseudosieboldianum(10.09). The results of DBH analysis of the major species having the high importance value showed the normal density distirbution of Q. mongolica, and Q. variabilis in Deogsan Provincial Park, so the dominance status of these species is likely to continue. Q. variabilis, Q. mongolica, and P. densiflora in Chilgabsan Provincial Park showed the normal density distribution showed the density of normal distribution, so the dominance status of these species is likely to continue. However, the dominance status of C. laxiflora, and Q. serrata is likely to be expanded in the future due to the high density of young individuals. Q. mongolica, and Q. variabilis in Daedunsan Provincial Park showed the density of reverse J-shaped curve, so the dominance status of these species is likely to continue, and C. tschonoskii, and P. densiflora had a formality distribution, suggesting continuous domination of these species over the other species for the time being. Additionally the dominance status of C. laxiflora, and Q. serrata is considered to be expanded in the future due to the high density level of young individuals.
