연구논문 : 제주지역 미세먼지의 장기변동 및 농도변화에 관한 국지기상 분석

박연희 ( Yeon Hee Park ),송상근 ( Sang Keun Song ),이수정 ( Soo Jeong Lee ),김석우 ( Suk Woo Kim ),한승범 ( Seung Bum Han ) 한국환경과학회 2016 한국환경과학회지 Vol.25 No.1

Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

한강 하류의 남조류 및 환경요인의 연간 (2000 ${\sim}$ 2003) 변화에 대하여

서미연,김백호,배경석,한명수,Suh, Mi-Yeon,Kim, Baik-Ho,Bae, Kyung-Seok,Han, Myung-Soo 한국하천호수학회 2005 생태와 환경 Vol.38 No.2

한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

GIS를 이용한 2차원 수치모형의 자연하천 적용

김병현 ( Byung Hyun Kim ),한건연 ( Kun Yeon Han ) 한국지리정보학회 2009 한국지리정보학회지 Vol.12 No.3

현재까지 개발되고 있는 대부분의 유한체적모형은 가상하도 및 실험하도와 같은 단순하도에 적용하여 흐름율과 생성항의 균형문제를 해결하기 위한 여러 가지 노력들이 있어 왔다. 하지만, 실제 자연하천에서의 적용에서는 단순하도에서의 적용에서 나타나지 않았던 여러 가지 문제점들이 발생하며, 이러한 문제점들을 수치적으로 해결하여야 비로소 자연하천에서의 적용이 가능하다. 본 연구에서는 자연하천에 적용가능한 2차원 유한체적모형을 개발하여 2차원 부분적 댐 붕괴에 적용하여 개발모형의 정확성을 검증하고, 한강의 측량단면을 GIS를 이용하여 2차원 격자에 정확하게 반영할 수 있는 간단하고 효율적인 2차원 격자생성기법을 제안하였다. 그리고 제안된 기법으로 생성된 2차원 격자로 한강에 대한 흐름모의를 수행하고 계산수위와 실측수위를 비교하여 자연하천에 대한 개발모형의 정확성 및 적용성을 입증하였다. A lot of efforts have been made to resolve balancing problems between flux and source term and most finite volume models under development have been applied to simple channels such as imaginary and experimental channels. However, a number of numerical problems which can not be found in simple channels occur in the application to natural rivers and the problems should be resolved to apply finite volume models to natural rivers. In this study, 2D finite volume model which is applicable to natural rivers was developed and the accuracy of the developed model was validated through the application of partial dam break In addition, a simple and efficient 2D mesh generation method was suggested and the method can be accurately reflected to 2D mesh converted from surveyed cross sections in Han-river using GIS. The accuracy and applicability of the developed model on natural rivers were verified by performing simulation on Han-river using the generated mesh and comparing computed water elevation with measured water elevation.

우극현,최광서,정영연,한구웅,박정한,이종협,Woo, Kuck-Hyeun,Choi, Gwang-Seo,Jung, Young-Yeon,Han, Gu-Wung,Park, Jung-Han,Lee, Jong-Hyeob 대한예방의학회 1992 예방의학회지 Vol.25 No.3

영상단말기 (VDT)작업이 시력과 안증상에 미치는 영향을 알아보기 위해 1991년 7월에서 10월 사이에 구미시의 1개 TV생산업체에 종사하는 근로자들 가운데 채용 당시 안과적으로 문제가 없었고, 나안시력이 1.0 이상인 40세 미만 남자 338명을 대상으로 일일 평균 화면작업시간이 4시간 미만인 근로자(I군, 60명)와 4시간 이상인 근로자(II군, 204명)를 폭로군으로 하고 유사한 작업환경에서 근무하는 비화면작업자(74명)를 비폭로군으로 나누어 연령, 작업경력, 교대근무형태, 확대경 사용유무, 1일 평균 TV시청 시간 및 수면시간과 그리고 안자각증상에 대한 설문조사를 실시한 후, 안과적검사를 시행하였다. 조사시 원거리시력 (양안의 평균시력)이 채용시에 비해 0.15 이상 저하된 비율은 II군이 20.6%로 비화면작업군의 14.9 %, I군의 15.0 % 보다 다소 높았으나 통계적으로 유의한 차는 아니었다. 연령, 작업경력, 확대경 사용유무, 교대근무형태 등에 따라 층화하여 원거리시력 저하율을 비교해 본 결과 세 군간에 통계적으로 유의한 차가 없었다. 근거리시력 저하율도 비화면작업군이 28.4 %, I군이 18.3 %, II군이 27.5 %로 통계적으로 유의한 차이가 없었으며, 연령 등 4가지 독립변수를 층화하여 비교해 보아도 유의한 차이가 없었다. 안자각증상 호소율은 안피로를 포함한 7가지 항목에서 눈물이 나는 것을 제외한 모든 항목에서 비화면작업군에 비해 I군이, I군 보다는 II군이 통계적으로 유의하게 높았다(P<0.01). 화면작업자 264명 가운데 조명이 나쁜 장소에서 일하는 근로자들의 원거리시력 저하율과 안자각증상 호소율이 조명이 좋은 작업장에서 일하는 근로자보다 더 높았다(P<0.05). 7가지 안자각증상을 각 증상 마다 늘 느끼는 경우는 2, 가끔 느끼면 1, 느끼지 않으면 0으로 점수화하여 개인별 총 안증상 점수를 구해 세 군간에 원거리시력 차이 유무별로 비교해 본 결과, 시력차 유무에 따른 평균 안자각증상 점수의 차는 없었으나 시력차 유무에 관계없이 II군의 평균 안자각증상 점수가 6.13 으로 I군(3.53) 또는 비화면작업군(3.30) 보다 훨씬 더 높았다(P<0.01). 안자각증상 점수와 유의한 상관관계를 보인 독립변수들은 화면작업시간, 확대경 사용유무, 교대근무형태 등이었고, 채용시와 조사시 원거리시력 차이, 원거리시력과 근거리시력 차이, 누액분비기능, 안압, 굴절력 등과 유의한 상관관계를 보인 독립 변수는 하나도 없었다. 안자각증상 점수를 종속변수로 하는 중선형 회귀분석 결과에서는 화면작업시간이 길수록, 단부제나 2교대 근무자보다 3교대 근무자에서 유의한 선형관계를 나타내었다(P<0.01). 본 조사에서는 1일 장시간 VDT작업으로 시력이 저하되는 것은 관찰할 수 없었고 안자각증상은 유발되는 것으로 나타났다. 안자각증상의 예방을 위해 VDT 작업장의 조명을 적절하게 유지하고 장시간 연속해서 작업하지 않도록 작업관리를 해야 할 것이다. This study was conducted to evaluate the effect of VDT work on eyes and vision among workers in a TV manufacturing plant. The study subjects consisted of 264 screen workers and 74 non-screen workers who were less than 40 years old male and had no history of opthalmic diseases such as corneal opacities, trauma, keratitis, etc and whose visual acuity on pre-employment health examination by Han's test chart was 1.0 or above. The screen workers were divided into two groups by actual time for screen work in a day : Group I, 60 workers, lesser than 4 hours a day and group II, 204 workers, more than 4 hours a day. From July to October 1992 a questionnaire was administered to all the study subjects for the general charateristics and subjective eye symptoms after which the opthalmologic tests such as visual acuity, spherical equivalent, lacrimal function, ocular pressure, slit lamp test, fundoscopy were conducted by one opthalmologist. The proportion of workers whose present visual acuity was decreased more than 0.15 in comparison with that on the pre-employment health examination by Han's test chart was 20.6% in Group II. 15.0% in Group I and 14.9% in non-screen workers. However, the differences in proportion were not statistically significant. The proportion of workers with decreased visual acuity was not associated with the age, working duration, use of magnifying glass and type of shift work (independent variables) in all of the three groups. However, screen workers working under poor illumination had a higher proportion of persons with decreased visual acuity than those working under adequate illumination (P<0.05) . The proportion of workers whose near vision was decreased was 27.5% in Group II, 18.3% in Group I, and 28.4% in non-screen workers and these differences in proportion were not statistically significant. Changes of near vision were not associated with 4 independent variables in all of the three groups. Six out of seven subjective eye symptoms except tearing were more common in Group I than in non-screen workers and more common in Group II than in Group I (P<0.01). Mean of the total scores for seven subjective symptoms of each worker(2 points for always, 1 point for sometimes, 0 point for never) was not significantly different between workers with decreased visual acuity and workers with no vision change. However, mean of the total scores for Group II was higher than those for the Group I and non-screen workers (P<0.01). Total eye symptom scores were significantly correlated with the grade of screen work, use of magnifying glass, and type of shift work. There was no independent variable which was correlated with the difference in visual acuity between the pre-employment health examination and the present state, the difference between far and near visions, lacrimal function, ocular pressure, and spherical equivalent. Multiple linear regression analysis for the subjective eye symptom scores revealed a positive linear relationship with actual time for screen work and shift work(P<0.01). In this study it was not observed that the VDT work decreased visual acuity but it induces subjective eye symptoms such as eye fatigue, blurred vision, ocular discomfort, etc. Maintenance of adequate illumination in the work place and control of excessive VDT work are recommended to prevent such eye symptoms.

한지혜,김재곤,백병주,양연미,이선영 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

백악질 골화성 섬유종은 가장 흔히 발생하는 섬유 골성 병소(fibro-osseous lesion)로서, 경계가 분명하고, 느리게 성장하는 팽창성의 양성종양이다. 임상적으로 하악골의 소구치와 대구치 부위에서 발생하고, 여성에게서 2배 정도 호발하며, 주로20대에서 30대 사이에서 발견된다. 백악질 골화성 섬유종은 섬유성 이형성증을 포함한 다른 섬유 골성 병소와 감별되어야 한다 백악질 골화성 섬유종의 또 다른 형태인 유년형 골화성 섬유종은 15세 이하에서 발생하며 빠르게 성장하고, 좀 더 골 파괴적인 양상을 보인다. 치료는 병소의 크기에 따른 절제술이고, 재발은 드물다고 알려져 있다. 본 증례는 우측 하악 견치의 미맹술을 주소로 내원한 12세 남자 어린이로, 백악질 골화성 섬유종으로 진단 후, 외과적 적출술을 시행하여 양호한 치유과정을 보이기에 보고하는 바이다. Cemento-ossifying fibroma of the jaws is well circumscribed, generally slow-growing, benign lesions which en-large in an expansile manner. Clinically, it presents as a slowly enlarging lesion commonly in the premolar-molar area of the mandible and only occasionally in the maxilla and other locations. It occurs twice as often in females and primarily in the 20 to 30 year age group. Differential diagnosis should be performed, preferably with other fibro-osseous lesions such as fibrous dysplasia. A faster growing and more destructive variant of cemento-ossifying fibroma sometimes occurs in patients under age 15 and is termed juvenile (aggressive) ossifying fibroma. Treatment is surgical removal with the extent depending on the size and location of the individual lesion. Recurrence is considered rare. A case involving a 12-year-old male patient with delayed eruption of right mandibular canine is discussed. Following an incisional biopsy, the histopathologic diagnosis established was cemento-ossifying fibroma. After the surgical enucleation of the lesion, no sign of recurrence was detected.

The purpose of this study was to investigate the effect of various cooking methods(roasted, salad, deep-fried, seasoned-roasted and commercial laver) on mineral contents, color and sensory evaluation of laver. The contents of mineral of dried laver by various cooking methods were analyzed using the Inductively Coupled Plasma(ICP) system. The results were summarized as follows : The content of crude protein, moisture, ash and crude fat in dried laver were 35.1%, 10.6%, 9.7% and 0.8%, respectively. Among the minerals of dried laver, the content of poassium was the highest (2268.0㎎/100g d.w.) and those of calcium and iron were comparatively high (495.1㎎/100g, 13.5㎎/100g). Ca/P ratio of dried laver was about 1:1 levels. Among various laver dishes, the total mineral content was the highest in the roasted laver, but low in the deep-fried laver. Among color values by cooking methods, "L(lightness)" and "-a(greenness)" values were the highest in the roasted laver, and "b(yellowness)" was the highest in the deep-fried laver. The seasoned-roasted laver was highly scored by the sensory evaluation.

SPICE을 利用한 硅素鐵心의 渦流에 대한 MODELING에 關한 硏究

韓運東,柳然國,梁桂儁 충주대 산업과학기술연구소 1998 産業科學論文集 Vol.6 No.-

The relation between the equivalent eddy current field He and the instantaneous flux density rate dB/dt is experimentally obtained for current transformer made of silicon steel. The results show that He is proportional to(dB/dt)-0.5~0.7 in the operating frequency range(~100Hz) of the current transformer. The AC B-H loop calcurated by combining the Jiles-Atherton model agrees well with the measured data. In addtion, this combined model allows magnetic component characteristics using SPICE to be simulated. The simulated secondary voltage waveforms of current transformers are in satisfactory agreement with the measured values.

Local self-sufficiency promotion center began to operate with the enforcement of the law for the securing of the least life of the people from October, 2000. It was made for the support of self-sufficiency of the poor who could work. As of December, 2006, 242 local self-sufficiency promotion centers are operating nationally. Their main business is to look after the patient, to repair the house, to clean, and to reuse the food. But now besides of these business, it widened its range from farming, eating out, helping mother who deliver a baby, and assisting the education of the disabled, to taking care of the old. The achievement of self-sufficiency business have inspired the will of life of the workers who took part in the self-sufficiency business and have promoted the vitality of them as components of the society by accepting their joining the social life in their community. This study has grasped the present condition of Chungbuk Association of Self-Sufficiency Promotion Center for the last 7 years and estimated its achievement and discussed the plan for the development of it.

Horseshoe Appliance를 이용한 Ⅲ급 부정교합의 교정적 접근

한지혜,김재곤,,백병주,양연미,서정아 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.4

성장기 아동의 Ⅲ급 부정교합의 치료에는 많은 악기능 정형장치가 사용되어 왔으며 다양한 형태로 변화하여 발전되어 왔다. Horseshoe appliance는 Schwarz에 의해 소개된 장치로서 elastic의 견인력으로 장치의 free sliding 효과를 통해, 하악와와 과두의 관계를 재정립시켜, 악골 주위의 연조직이나 muscle matrix와 조화되는 새로운 위치에 하악골을 repositioning시켜 악골관계를 개선시킬 수 있다. 또한 하악의 후하방 회전 효과를 극소화시켜 전안면고경의 증가를 방지할 수 있고, 구외 장치에 비해 환자의 협조도가 좋다. 저자들은 전치부 반대교합을 주소로 전북대학교 치과병원 소아치과에 내원한 Ⅲ급 부정교합 환자에게 Horseshoe appliance를 사용한 결과 하악골에 대한 상대적인 상악골의 전방 성장과 교합평면의 반시계방향 회전, 상악 전치의 순측 경사와 하악 전치의 설측 경사로. 3개월 내에 전치부 반대교합이 해소되는 효과를 얻었다. The Horseshoe appliance was introduced by Dr. Schwarz, and it is used to correct sagittal relationships by elastic force in class Ⅲmalocclusion.It minimizes the increment of lower anterior facial height and allows the mandible to be repositioned harmoniously with the soft tissue and muscle matrix of the jaw. It has the advantages of better patient cooperation, easier construction, and more effective modification. In the patients who were treated with Horseshoe appliance, forward growth of maxilla and counterclockwise rotation of occlusal plane with labioversion of maxillary incisors and linguoversion of mandibular incisors were obtained Minimum downward and backward rotation of mandible was accepted, so increasing of lower anterior facial height was minimized.
