<P><B>Abstract</B></P> <P>This study quantified carbon storage and uptake for urban parks in Seoul, the capital of the Republic of Korea. A total of 38 study parks were selected using a systematic random sampling method and all the trees in the parks were field-inventoried. Carbon storage and uptake by the park trees were estimated applying a quantitative model for urban open-grown trees of each species. Mean carbon storage per unit of park area, basal area, and crown cover by the trees was 38.5 ± 3.0 t/ha, 27.3 ± 0.8 kg/100 cm<SUP>2</SUP>, and 7.4 ± 0.4 kg/m<SUP>2</SUP>, respectively. Annual carbon uptake per unit area and cover by the trees averaged 3.5 ± 0.2 t/ha/yr, 2.5 ± 0.1 kg/100 cm<SUP>2</SUP>/yr, and 0.7 ± 0.0 kg/m<SUP>2</SUP>/yr, respectively. The major determinants of the levels of carbon storage and uptake were species, density, sizes, and layering structures of the planted trees. The trees across all urban parks in Seoul were estimated to store 222.3 kt of carbon and to annually sequester 20.2 kt of carbon. The trees in these parks played an important role in annually offsetting carbon emissions from gasoline consumption by approximately 2.3% of the total population of the city. The economic value of the annual carbon uptake, which was $7.1million/yr, equaled 15.1% of the annual maintenance budget of the parks in the city. However, the role of study parks as a source of carbon uptake was limited due to the distribution of large grass and impervious areas, the single-layered structures, and the dominance of small trees. Planning strategies were explored to enhance carbon reduction effects of the parks. They included the expansion of tree planting spaces through the minimization of unnecessary grass and paving areas, the active tree planting in the potential planting spaces, the multi-layered planting grouped with larger trees, and the planting of tree species having satisfactory growth rates. This study puts an emphasis on finding out the present carbon offset levels of urban parks on which information is limited and suggesting a future direction of park planning based on a detailed actual survey.</P>

Duodeno-colonic fistula is an enterocolonic fistula that occurs as a complication of Crohn`s disease. Symptoms of duodeno colonic fistula are similar to those of Crohn`s disease, such as weight loss and diarrhea. The treatment of choice is surgery, although medical treatment may also be considered. However, surgery is recommended when all available medical therapies have been ineffective. In this case, we report a secondary duodeno-colonic fistula due to Crohn`s disease that was temporarily managed by an endoscopic procedure with a detached endoloop and hemoclips as a bridging therapy to final surgical repair.

High-quality meat is of great economic importance to the pig industry. The 1-acylglycerol-3- phosphate-O-acyltransferase 5 (AGPAT5) enzyme converts lysophosphatidic acid to phosphatidic acid in the mitochondrial membrane. In this study, we found that the porcine AGPAT5 gene was highly expressed in muscle tissue, influencing meat characteristics, and we also identified a non-synonymous single-nucleotide polymorphism (nsSNP) (rs196952262, c.673 A>G) in the gene, associated with a change of isoleucine 225 to valine. The presence of this nsSNP was significantly associated with meat color (lightness), lower cooking loss, and lower carcass temperatures 1, 4, and 12 h after slaughter (items T1, T4, and T12 on the recognized quality scale, respectively), and tended to increase backfat thickness and the waterholding capacity. These results suggest that nsSNP (c.673A>G) of the AGPAT5 gene is a potential genetic marker of high meat quality in pigs.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

漢詩 敎育의 必要性 및 指導方案

朴美惠 한국한자한문교육학회 2002 漢字 漢文敎育 Vol.9 No.-

In21century, informational age makes an amazing changes and development of life. but on the other hand, it gives us a critical crisis in literature. after all, many people become to prefer convenient mass media, such as movies, videos, and televisions to reading books devastating their times. among them the lyricism , represented by the Chinese character poetry , has lost its' existential basis because it is far from the demand of the moderns, who only seek after the interest and practicality. The Chinese poem should not be treated lightly in the aspect of its role : Firstly, it can stimulate the cold-hearted modern people's sensibility. Secondly it make us discern the ancestors' wisdom of life through the poem. Thirdly it can give us an indirect experience with our imagination. Lastly it can let us appreciate the typically refined language of its own. It is a matter of course that we have to devise an efficient teaching methods of Chinese poem (which enable the students to learn it more easily and excitingly) instead of pattern drill memorizing method to deliver the value of it. Nowadays it changes extremely rapidly through the power of machine civilization. And there are many people who doubt the value of the past literature, Chinese poem not only cure and complement the dark side of mechanical development era, but also stimulate our emotion and be our mental resources stimulating our mind.

Alcaligences에 의해 생산되는 새로운 Hetero-다당류인 Welan Gum과 Xanthan Gum의 Rheology특성에 관한 비교 연구

박혜정,김미옥,구성자 경희대학교 유전공학연구소 1989 遺傳工學論文集 Vol.1 No.-

Alcaligences로부터 추출된 새로운 미생물 다당류인 Welan gum 과 Xanthanonas campetris 의 발효에 의해 얻은 Xanthan gum의 rheology 특성을 비교 검토하였다. 그 결과 Welan gum의 고유점도는 pH7에서 염을 가하지 않는 상태에서는 Xanthan gum 보다 훨씬 낮았으나 0.1 M-KCI 용액중에서는 비슷한 값을 나타냈다. pH, 온도 및 염농도 의존성은 Welan gum 이 더 안정하였으며, 농도 의존성은 두 시료 모두 pseudoplastic 거동을 나타냈다. 또한 Welan gum과 Xanthan gum은 각각 0.056g/dl 및 0.024g/dl 농도 이상에서 entanglement coupling 이 일어났으며, 염종류에 대한 영향은 1 가염(KCl, NaCl), 2가염(MgCl_(2), CaCl_(2)) 및 Urea에 대해 Welan gum 이 더 안정하였다. The polysaccharide produced by Alcaligence, Welgan gum, was rheologically characterized and compared with Xanthan gum, To evaluate the potential function of Welan gum and Xanthan gum, the physical properties of the gums were determined under various solution conditions. Rheological properties of the gums were determined by measuring intrinsic viscosity of the solution in the different pH and salt concentration. At the range of pH 2-11 and salt 0-1.00 M-KCl, the intrinsic viscosity of Welan gum was ranged from 13.65 to 17.90 dl/g and Xanthan gum was ranged from 8.19 to 41.8dl/g. In the absence of salt, the instrinsic viscosity of Welan gum was not affected by increasing pH of the solution, whereas the intrinsic viscosity of Xanthan gum was appeared maximum at the neutral pH, then decreased both acidic and alkalic pH. Intrinsic viscosity of Welan gum was not affected by increasing salt concentration, whereas intrinsec viscosity of Xanthan gum was decreased with increasing salt concentration. The chain stiffness parameter for the Welan gum was 0.01, for Xanthan gum was 0.005. The overlap parameter of Welan gum and Xanthan gum were 0.056 dl/g and 0.024 dl/g, respectively Welan gum and Xanthan gum were showed shear rate dependent or pseudoplastic. The apparent viscosity of Welan gum and Xanthan gum were decreased as the shear rate increased. The yield stress, proportionality constant, and shear index of Welan gum were increased slightly as the concentration of the gum was increased. The apparent viscosity of Welan gum was decreased slightly by increasing temperature, whereas Xanthan gum was decreased In the presence of salts (KCI, NaCl CaCl_(2), MgCl_(2) and urea). Welan gum was not affected and Xanthan gum was affected slightly.
