<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.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

본 연구는 스트레스 반응을 측정하는 스트레스 반응 척도 설문지(Symptoms of Stress: SOS)를 이용한 횡단적 연구로서 심신수련의 하나인 기수련이 스트레스 반응에 미치는 효과를 살펴보았다. 72명의 건강한 정상인과 180명의 기수련자를 대상으로 하여 조사하였으며, 기수련자들은 수련기간에 따라 초급군(1-4개월; 64명), 중급군(5-12개월; 50명), 고급군(1년 이상; 66명)로 나누었다. 실험결과 1년 이상 수련한 기수련자들이 말초혈관 증상군, 심폐 증상군, 중추신경계 증상군, 위장계증상군, 습관적 행동 형태군, 우울 증상군, 불안증상군등의 스트레스 반응 하위척도에서 대조군에 비해 통계적으로 유의하게 감소하였다. 전체 스트레스 값은 대조군에 비해 기수련자 집단이 아주 낮았으며 수련기간이 길수록 감소하였다. 이러한 결과는 기수련이 스트레스 중재와 스트레스 증상을 줄이는데 효과가 있음을 나타낸다. We examined the effects of Qi-training, one of Korean traditional psychosomatic training, on stress coping ability by cross-sectional investigation with inventory of symptoms of stress (SOS). Four types of groups- normal healthy (n-74), three groups of Qi-trainees (group primary level: subjects with Qi-training for 1-4months, n=64; middle level: 5-12 months, n=50; high level: more than 12 months, n=66) participated in this study, Qi-trainees with over 1 year training had significantly lower scores in all SOS subscales compared to controls. Total stress scores of Qi-trainee groups were substantially lower than controls and further reduction with larger training periods. These results suggest Qi-training is effective in stress management and decreasing symptoms of stress
