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.

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.

목적: To evaluate the cumulative recurrence rate of endometriomas after a laparoscopic endometriotic cyst enucleation in adolescents and to find the factors associated with recurrence. 방법: A multicenter retrospective cohort study was performed at 3 gynecologic surgery centers between January 2000 and December 2010. Patients surgically treated by laparoscopic enucleation of endometriotic cysts younger than 20 years old were selected. We excluded patients who had reproductive tract anomalies. Endometrioma recurrence was considered when transvaginal or transrectal sonography indicated a cystic mass with a diameter of ≥ 20 mm. 결과: In total, 105 patients were followed up for 47.3 ± 44.3 months (range, 3 - 161 months). Seventeen patients (16.2 %) experienced recurrence after the first-line surgery and 8 patients (7.6 %) underwent a second surgery. The median time to recurrence was 51.1 ± 9.1 months (SEM) (range, 8 - 111 months). The cumulative recurrence rates of endometrioma per patient at 24, 36, 60 and 96 months after the first-line surgery were 6.4 %, 10 %, 19.9 % and 30.9 %, respectively. Surgical characteristics such as the diameter of the cyst, rAFS stage, unilateral or bilateral involvement, co-existence of deep endometriosis were not associated with the recurrence in this age group. 결론: The short-term recurrence rate in adolescent after the first-line surgery is relatively low but is appears to be higher according to the follow- up duration. Long-term and strict follow up is needed who have undergone surgical treatment for endometriosis in adolescent period.

MPEG 비디오 데이터를 이용한 움직이는 물체 추출 방법

김선우,최연성,박한엽 군산대학교 정보통신기술연구소 2000 情報通信技術硏究論文集 Vol.4 No.-

In this paper, we describe a method of moving object extraction directly using MPEG video data. Since motion information in MPEG coded data is determined in terms of coding efficiency point of view, it does not always provide real motion information of objects. We use a wide variety of coding information including motion vectors and DCT coefficients to estimate real object motion. Since such information can be directly obtained from coded bitstream, very fast operation can be expected. But, this bitstream have don't need noise because of illumination and H/W feature. In this paper, we proposed that the method is using median operator to exclude noise. Moving object are detected basically analyzing motion vectors and spatio-temporal correlation of motion in P- and B-Pictures. The simulation results show that successful moving object detection has been performed on MB level using several test sequences. Since proposed method is very simple and requires much less computational power than the conventional object detection methods, it has a significant advantage as motion analysis tool.

Pulmonary sequestration is a rare congenital lung disease. It is classified as intrapulmonary sequestration, having own visceral pleura, and extrapulmoanry sequestration, not having own visceral pleura. We experienced two cases of intrapulmonary pulmonary sequestration. Two cases were developed in right lower lobe of lung. A 31 year old man had coughing, sputum, and febrile sensation for 2 months. He had antituberculosis medication because he was misdiagnosed as pulmonary tuberculucosis. The sequestrated lung was supplied by systemic artery originated from descending thoracic aorta. Another 58-year-old woman had symptoms of recurrent upper respiratory infection occurring over a seven-year period. We couldn't find aberrant artery form 2nd case. We performed lobectomy in two cases and patients were treated successfully without complication.

The ankle joint is a modified complex hinge joint which plats an important vital role in normal gait, walking and weight bearing. The goal in the treatment of ankle fracture is the restoration of full function to the injured extremity such restoration can be accomplished only with full appreciation of the fracture, the concomitant soft tissue injuries and mechanical demands of the joint involved. The authors have reviewed a series of 131 cases of ankle fractures which were admitted and treated in orthopaedic department of Sunchunghyang university from Feb. 1994 to Oct. 2000. Among the 131 cases ,69 patients (52.7%) were male, and 62 patients (47.4%) were female. Peak incidence of age was 20-30 years old (55 cases, 42.5%). The main causes of injuries were slip down (84 cases, 64.1%) and the other causes were traffic accident (24 cases, 18.3%), rolling down (7 cases, 6.3), fall down (6 cases, 4.6%), direct blow (5 cases, 3.8%), sports injury (4 cases, 3.1%), human trouble (1 cases, 0.7%) in order. Accompanying injuries were noted on 32 case (23.4%) and fractures in lower extremities were most common (15 cases, 46.9%). Supination-external rotation injuries were most common by the Lauge-Hansen classification (53 cases, 40.5%) and type B ankle injuries were most common by the Danis-Weber classification (67 cases, 51.2%) type B2 ankle injuries were most common by the AO classification (44 cases, 33.6%). Open reduction was performed in 95 cases (72.5%) and closed reduction was performed in 36 cases (27.5%). The result was better in those cases which were treated by open reduction and internal fixation than those by closed reduction. SO anatomical reduction and firm internal fixation of the fibula and repair of the distal tibiofibular ligament or transfixation of the distal tibiofibular joint with screw were thought to be very important in the management of the ankle injuries.

CNPA는 기존의 폐질환 및 폐절제술로 인해 국소방어기전에 저하가 있거나 비특이적 전신면역상태저하를 갖고 있는 환자들에게서 주로 발생하는 만성적인 공동성 폐질환이다. 현재까지 우리나라에서는 CNPA의 보고가 없는 상태이고, 저자들은 최근 조직학적으로 진단된 CNPA 2예를 경험하였기에 보고하는 바이다. 저자들이 경험한 CNPA 환자들은 만성알코올 중독 및 기관지확장증과 같은 기저질환과 폐절제술을 받은 병력이 있었다. Aspergillus가 폐실질을 침윤하고 있는 조직소견과 조직배양에서 Aspergillus가 검출되어 조직학적 진단이 가능하였고, amphotericin B의 정주요법 및 경구 itraconazole 투여와 폐절제술 등으로 성공적으로 치료되었다. 아직 많은 임상의들에게는 낯선 질환인 CNPA의 치료성적은 환자의 동반질환 및 CNPA 자체의 중증도, 진단과 치료 시작의 지연 등에 의해 크게 좌우되므로 만성적으로 진행하는 공동성 폐병변을 갖고 있는 환자에게서 CNPA를 감별하는 것이 중요하다. Chronic necrotizing pulmonary aspergillosis (CNPA) is a chronic cavitary form of pulmonary aspergillosis. Dozens of CNPA cases have been reported in patients with systemic immunologic dysfunction or altered local defense mechanism from preexisting pulmonary disease. Review of literatures revealed that no CNPA cases have been reported in Korea yet. We experienced two cases of CNPA proven by lung biopsy. A 53-year-old alcoholic male in poor nutritional state was admitted with generalized weakness and weight loss. Chest CT revealed a cavitary nodule surrounded with ground-glass attenuation. CT-guided fine needle aspiration and biopsy was done. The biopsy specimen demonstrated dichotomously branching septated hyphae consistent with those of Aspergillus sp. Another case was a 39-year-old man with bronchiectasis who was admitted with persistent hemoptysis. He had a past history of pulmonary tuberculosis. A parahilar lesion with intracavitary soft tissue mass was incidentally detected in high-resolution GT. Left lingular segmentectomy was done due to uncontrolled hemoptysis and CNPA was histologically diagnosed. Both patients were successfully treated with intravenous amphotericin B followed by oral itraconazole. Even though CNPA is unfamiliar to most clinicians, it should be included in differential diagnoses of chronic progressive cavitary pulmonary lesion, especially in patients with immunologic dysfunction.

Objectives : The Internalized Stigma of Mental Illness (ISMI) scale designed to measure the subjective experience of stigma with sub-scales measuring Alienation, Stereotype Endorsement. Perceived Discrimination, Stigma Resistance, and Social Withdrawal. The purpose of this study was to examine the reliability and validity of the Korean version of ISMI. Methods : The subjects were 194 schizophrenic patients and 205 peoples with depressive disorder. K-ISMI, CES-D (The Center for Epidemiologic Studies Depression Scale) and Self Esteem scale were performed. Results : Results showed that the ISMI had high internal consistence and split-half reliabilities. The internal consistency coefficients (Cronbach alpha) of each subscale ranged from .83 to .93. The validity of the ISMI was investigated by principal axis factoring analysis, yielding 5 factors of alienation, Perceived discrimination, negative stereotype, stigma resistance, devaluation and social withdrawal. 5 subscales explained 60.67% of total variance. Concurrent validity was supported by comparisons against scales measuring related constructs. As expected, the ISMI had positive correlations with CES-D, and it had negative correlation with self-esteem scale. Subsidiary analysis showed that schizophrenic patients showed higher internalized stigma than depressed patients. Conclusion : Overall, the findings support the utility of ISMl as a tool to evaluate internalized stigma of persons with mental illness. Interventions that can lessen internalized stigma may well hasten the recovery process in individuals with mental illness.
