이 연구는 국내 토양오염과 광주광역시 토양 오염도의 통합적인 정량화에 따른 중금속의 변화에 관한 연구이다. 연구결과 국내의 토양오염과 광주광역시의 토양 오염도의 정도는 1998, 1999, 및 2000년을 비교하여 본 결과 공장요지 및 철도 용지에서는 카드뮴, 구리, 납의 오염도가 다른 토지용도에 비하여 높게 나타난 것이 특징적이며, 광주광역시는 1998및 1999년도를 비교하여 본 결과 구리와 비소만이 약간 증가하였고 나머지 중금속들은 감소하였다. 광주광역시는 하남공단과 본촌공단 내에서의 유류 유출은 없는 것으로 판단되며, 밭 토양에서 약간의 유류가 검출되었는데 이는 주변의 주유소의 영향으로 생각되어진다.그러나 전국적인 평균에 비한다면 아주 청정한 토양이다. 전반적으로 토양오염 측정망이 가동된 기간이 매우 짧아서 정확한 판단을 내리기는 어려우나 납의 변화량이 가장 큰 변위를 나타내는데 측정망 원년에 가장 높은 수치를 나타내며 1998년에 약간 감소하다 1999년에 상승하고 2000년에는 다시 감소한는 경향을 보이고 있다. 카드뮴은 증가 추세를 보이고 있고 수은과 시안은 감소 추세를 보이고 있다. This study is a change of heavy metals according to integrative fixed quantity on soil pollution level in domestic area and Gwangju city. As a result of the study which compared with the 1998,1999 and 2000 years data, it is characterized that Cd, Cu, Pb, pollution level of national and GwangJu metropolitan city in factiry sites and railway sites are higher than other sites. The study also showed that only Cu and As were slightly increased and other heavy metals was decreased. It is believed that there is no evidence of oil spill pollution in Hanam and Bonchon industrial complex of Gwangju city. But some oil was detected by chemical analysis in field area, it is thought as the effect of gas stations in the neighborhood. On the whole it is difficult to make an accurate conclusion because of the very short term of operating soil pollution survey net. The change amount of lead shows the biggest displacement. It shows the highest figure the first year of survey, and it has a little decline in 1998. The figure goes up in 1999, and drops again in 2000. Cd is on an increasing trend, but Hg and CN is the opposite situation.

Background and Objectives: With increasing age of population, stroke and dementia become greater health problems in Korea. However, there have been no studies on poststroke dementia in Korea. We intended to elucidate the frequency and clinical correlates of poststroke dementia in a hospital-based cohort. Methods: From July 2001 to July 2002, 372 patients were hospitalized to Eulji General Hospital within 7 days from onset with acute stroke or transient ischemic attack. Two hundred-eight patients (55.9%) were followed up and interviewed more than 1 year later (451 ±83.3 days). Dementia was diagnosed by Korean Dementia Screening Questionnaire (KDSQ) obtained by a direct interview. Based on Eulji Stroke Registry, demographic factors, risk factors for stroke, stroke characteristics, and stroke outcomes were gathered and examined. Results: Of 208 patients, poststroke dementia was detected in 36 patients (17.3%, 20 males, age=64.5±9.4 years). Poststroke dementia was associated with history of stroke, aphasia, modified Rankin Disability Scale (MRDS) at 3 month after stroke and when interviewed, and Barthel index at 6 months after stroke (p;0.05). Its correlation with diabetes mellitus and National Institute of Health Stroke Scale at discharge were marginally significant (0.05;p;0.1). Conclusions: Post-stroke dementia is common in Korean stroke patients. Its frequency is comparable to that in other countries. The correlates of poststroke dementia and their clinical meanings are demonstrated.

The blepharoptosis is the disease which is caused by the congenital or acquired weakness of the levator palpebrae superioris. From September 1984 to December 1992, authors had treated 19 blepharoptosis patients(22 cases of operation), and the operative procedures were chosen according to the patient's levator function : levator resection in cases with levator function above 4mm(6 cases), frontalis transfer in cases with levator function below 2mm(5cases), levator resection(7cases) or frontalis transfer(4 cases) in cases with levator function between 2-4mm. And the operative results were evaluated with the average follow up period of 34.5 months. The results were summarized as follows. 1. 15patients were congenital and 4 patients were acquired type of blepharoptosis and sex ratio was 11:4(male:female) in 15 congenital blepharoptosis patients. 2. We performed 13 cases of levator resection and 9 cases of frontalis transfer. 3. In cases of moderate blepharoptosis, whose levator function is 4-8mm or 2-4mm, results of levator resection and the frontalis transfer are both good. 4. In cases of severe blepharoptosis, whose levator function is 2-4mm, result of levator resection is relatively fair, the frontalis transfer is good. 5. Results of frontalis transfer in acquired type showed excellent regardless of levator function. 6. The incidence of undercorrection after levator resection in congenital blepharoptosis was 72.7%, and the frontalis transfer showed frequent severe complication such as persistent lagophthalmos, exposure keratitis, hollowness of temporal area, headache, overcorrection & undercorrection.

친수성으로 표면개질한 폴리설폰막의 투과플럭스

송근호,김강희,조성헌,이광래,임종호,배성수 한국화학공학회 2004 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.42 No.1

실관막형 폴리설폰 막의 표면을 2-hydroxyethylmethacrylate(HEMA)로 코팅하였으며, 코팅인자들인 azobisisobutyronitrile(AIBN)/HEMA 성분비, 용매의 종류(물, 메탄올), UV 조사시간 등이 투과플럭스에 미치는 영향을 조사하였다. AIBN/HEMA/ 메탄온ㄹ 용액으로 코팅한 막이 AIBN/HEMA 성분비가 높고, UV 조사시간이 길수록 투과플럭스가 높았다. AIBN/HEMA 성분비가 낮으면 동일한 투과플럭스를 얻기 위하여 UV조사시간을 더 길게 하여야 하며, 특정한 AIBN/HEMA 성분비와 UV 조사시간에서 코팅한 막의 투과플럭스는 원래의 막(코팅하지 않은 막)보다 높게 나타났다. 또한, 오일에멀젼에 의한 fouling은 코팅한 막과 원래의 막에 모두 나타났지만, 코팅한 막의 fouling이 원래의 막 보다 현저히 낮았다. 즉, fouling 발생 후 코팅한 막의 수투과 플럭스(0.2683g/㎠ㆍmin)는 코팅하지 않은 막(0..448g/㎠ㆍmin)보다 약 6배 이상으로 높게 유지되었다. A hollow-fiber type polysulfone UF membrane was surface-coated with 2-hydroxyethylmethacrylate(HEMA). The effect of various coating paramters on permeation flux was investigated, such as concentration ratio of Azobisisobutyronitrile(AIBN)/HEMA, solvent (water or methanol), and UV irradiation time. The membrane coated with a solution of AIBN/HEMA/methanol showed about 2.65 times higher water flux than that coated with a solution of AIBN/HEMA/water. The membrane coated with a solution of higher AIBN/HEMA ratio and a longer UV irradiation time exhibited a higher permeation flux. The membrane coated with a solution of lower AIBN/HEMA ratio needed a longer UV irradiation time for coating to get a same level of permeation flux. In order to have a greater permeation flux than uncoated membrane, the membrane should be coated with a solution of a certain AIBN/HEMA ratio and UV irradiation time. The fouling by oil emulsion occurred to both of the coated and the uncoated membrane. However, the fouling of coated membrane was much less than uncoated one; the water flux(0.2683g/㎠·min)through the coated membrane was about 6 times higher than that(0.0558g/㎠·min) through the uncoated membrane.

The aim of this study was to consider the burn out issue, one of the most serious problems in sports, through the actual examples of people who has high performance goal(PG) tendency and, did not snow helpless responses nor stop working for a nest goal in spite of losing an important game after hard efforts. The result of the investigation, which is conducted by questionnaire, are as follows : Players who did not show the helpless response were more affirmative to their process and results, and furthermore, the players who were given a chance to play showed the same tendency remarkably. The result indicated the importance of a coach to utilize daily training and to encourage players' motivation without negative actions such as to 'change one's cognition from PG to LG(Learning Goal)' or 'take competitive environment away from players'.

To utilize coastal aquaculture ground bottom sediment in which concentrations of harmful pollutants are low and organic content is high as an organic fertilizer alkaline stabilizers such as CaO, Oyster shell, Mg(OH)_2 were added to the bottom sediment organic additives of livestock or food wastes. Nutritive qualities of crude fertilizers were measured to examine effects of alkaline stabilizers and organic waste additions. The Mg(OH)_2-added crude fertilizer had significantly lower total carbon(T-C) and nitrogen(T-N) content, reflecting the dilution effect due to great amount of Mg(OH)_2 addition. However, the addition of oyster shell had no significant effect on the T-C and T-N content of the fertilizer. P_2O_5 and K_2O content was considerably higher in the mixed of aquaculture ground bottom sediment and livestock wastes than in the mixture of the sediments and food wastes, resulting from higher P_2O_5 and K_2O content in livestock wastes. Addition of Mg(OH)_2 increased the content of MgO in the crude fertilizer but significantly reduced the content of other nutritive elements such as P_2O_5, K_2O and CaO. Addition of oyster shell as an alkaline stabilizer seemed to have the advantage of saving time and expenses for dryness due to role as a modulator of water content. Moreover, additions of effect Mg(OH)_2 decreased the concentrations of heavy metals in the fertilizer by the dilution while additions of oryster shell had no influence on heavy metal concentrations in the fertilizer.
