To characterize the elemental composition of fine particles in urban area, $PM_{2.5}$ was collected by a 3-stage DRUM impactor at Gwangju during spring and summer. Time and size resolved concentrations for 19 trace elements were obtained by synchrotron X-Ray fluorescence analysis. Trace elements in summer were distributed in smaller size range compared to those in spring. Almost trace element concentrations in fine particles were highly increased during the Asian dust. In spring, soil elements such as Si, K, Ca, Ti and Fe had low enrichment factors indicating the dominant influence of soil dust. However, all elements had high enrichment factors in summer implying that these elements could be emitted from the anthropogenic sources. Factor analysis was conducted with the elemental composition data in order to identify anthropogenic sources of aerosols in urban area during spring and summer. Fine particles in spring have several sources such as soil dust originating from China continental region, coal and oil combustion, biomass burning, sea salt, ferrous and nonferrous metal sources. On the other hand, fine particles in summer were influenced by road dust, gasoline vehicle as well as coal and oil combustion, sea salt, ferrous and nonferrous metal sources.

This study aims to determine the community patterns of benthic macroinvertebrates and analyze the relationship between the communities and the water quality in the Pungyeongjeong Stream. We collected the samples four times by season. The number of species was 28 and the dominant species were Cheumatopsyche brevilineata, Hydropsyche kozhantschikovi, Baetis fuscatus, Chironomidae spp., and so on. The range of the dominant index was 0.54 to 0.93 and the mean was 0.77. The range of the diversity index was 0.94 to 2.54, and of the mean index it was 1.75. The ratio of filtering-collectors and clingers got lower, but the ratio of gathering-collectors and sprawlers got higher as collection progressed from the upper stream to the lower stream. The results of the Pearson correlation analysis showed COD, SS, TOC and total coliforms were highly related with biotic indices of benthic macroinvertebrates. The results of cluster analysis and non-metric multidimensional scaling ordination showed that the survey sites and periods were divided into three groups. The survey sites were divided into upper stream and middle-lower stream. The survey periods were divided into winter season and other seasons. Distribution of benthic macroinvertebrates showed some characteristics according to various influence factors; however long-term and regular investigations were thought to need analysis and prediction with various statistical methods.

Objective: The purpose of this study was to investigate the clinical effects of BU pharmacopuncture therapy consisting of bear's gall(fel ursi) and ox bezoar(bovis calculus) on acute lumbar sprain. Methods: 12 patients diagnosed as acute lumbar sprain in 6 designated local Korean medicine clinics from October 2017 to February 2018 were treated by BU pharmacopuncture. Several acupoints in abdomen and lumbar region were selected by clinicians at their own discretion. The effectiveness of the therapy was evaluated using VAS and ODI. After that we reviewed the medical records of all these patients to evaluate the effectiveness and safety of the therapy. Results: The VAS and ODI scales were significantly decreased after BU pharmacopuncture therapy. And no major complications and adverse effects were reported. Conclusion: BU pharmacopuncture showed rapid pain relief in patients with acute lumbar sprain. It is possible to shorten the treatment period of acute lumbar sprain and prevent progressing to chronic back pain in advance. To establish the effects of BU pharmacopuncture therapy, more succeeding clinical and laboratory studies are needed.

The six-year (2000~2005) record of aerosol optical thickness (AOT or $\tau$) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) was analyzed over the Northeast Asia. The MODIS AOT standard products (MOD04_L2) over both ocean and land were collected to evaluate the spatial and temporal variability of the atmospheric aerosols over the study region ($32^{\circ}N{\sim}42^{\circ}N$ and $115^{\circ}E{\sim}133^{\circ}E$). The monthly averaged AOT result revealed slight changes(${\pm}0.002{\tau}/month$), which was almost unchangeable, over Korea. In contrast, the large AOT values (> 0.6) and a significant AOT increase (> 0.004 ${\tau}/month$) over East China were observed. For the analysis of spatio-temporal variability of AOT values, study area was divided by six sectors (I: North-East China, II: East China, III: Yellow Sea, IV: Korea Peninsular, V: East Sea, and VI: South Sea and Western part of Japan). The considerable result showed that particularly high AOT contribution was observed over sector I (32.5%) and II (25.5%) where some major urban and industrialized areas and agricultural fields are located and other cases were observed 13.2%, 14.6%, 7.1%, 7.0% over sector III, IV, V, and VI, respectively. In addition, yearly AOT changes based on seasons are observed differently at each sector but increasing trends reveal in summer and fall over all sectors.

이 연구는 우리 사회의 지역 간, 세대 간 여론양극화 현상의 양태를 살펴보고 여론양극화 현상에 영향을 미치는 요인들이 무엇인지를 검증하고자 하였다. 분석 결과 전국이슈에서 실제 지역 간 여론차이는 없었으나 여론지각과 지각편향에서 차이가 있었고, 지역이슈에서는 실제 여론차이가 있었으나 여론지각과 지각편향의 차이가 더 심하게 나타나 여론양극화 현상은 실제 여론의 차이보다는 지각된 여론에 기인한 것임을 알 수 있다. 부산은 자기 지역여론에 대해 보수편향을, 타 지역 여론에 대해서는 진보편향을 보였고, 광주는 자기 지역여론에 대해서는 거울반사인식을, 타 지역 여론에 대해서는 보수편향을 보였다. 또한 각 지역여론에 대한 두 지역의 지각이 유사하여 상대지역에 대한 스테레오타입화된 태도나 믿음에 근거해 여론지각이 이루어지고 있음을 알 수 있다. 세대 간 여론양극화 현상은 유의미하지 않았으며, 모든 세대가 대체로 다른 사람들이 자신보다 보수적이라는 보수편향을 보였지만, 지역 간 여론지각에서는 이슈에 따라, 세대에 따라 지각편향이 다르게 나타났다. 지역과 세대를 교차 비교한 결과 전국이슈에 대한 실제의견을 제외하고 세대별로도 지역 간 여론양극화 현상이 나타났다. 한편 회귀분석 결과 개인의 의견과 지역은 여론 및 여론지각, 지각편향을 설명하는 매우 예측력 높은 변인이었으나 세대의 설명력은 디지털 세대에서만 약하게 나타났다.

This investigation has been carried out for the purpose of the examination of current Gwangju and Jeonnam clinical pathology students' recognition of their departments and of effective employment guidance. Furthermore, it has examined the students' recognition on two sides; namely, their satisfaction with their own departments and their recognition of the employment of medical technologists. This investigation, with 389 students as its subjects from the clinical pathology departments at 4 universities in the Gwangju-Jeonnam Region, has compared and analyzed the data from the survey with a questionnaire from November 2008 to June 2009 by using the SPSS 12.0 package. Some of the remarkable results from the yielded data are as follows. As for the motivation for their application to the clinical pathology departments, the investigation of the students' satisfaction with their departments has revealed that 47.5% of the subjects indicated recommendation from friends or acquaintances while 22.1% reported that they had been informed of the departments through Internet. 70.4% of the subjects graduated from general high schools, 22.3% from commercial high schools, and 6.2% from technical high schools. Applicants from general high schools tend to decrease in number every year. 28.5% of the students judged professor's capability of lecture as an important part of their acquisition of licenses, and more than 65.6% of the subjects acknowledged the necessity of their self-study at night for the acquisition of license. As for the future prospect of the occupation of clinical technologist, 46.8% of the students replied that it was promising, while 39.1% reported that they had no ideas. From this we can confirm that the students of clinical pathology lacked a viewpoint of occupation and goals for future jobs. The investigation of the students'recognition of the employment of clinical technologists has revealed that 47.8% of them wanted to be employed in the Seoul-Gyeonggi Region due to the properties of their local universities, 29.0% of themlogpecteties of monesly salary to be 1,200,000~1,300,000 won, while 22.4% 1,300,000~1,400,000 won. These fiemres indicated that these students' salary ogpectations were relativplo lower than those from cities ertiprovinces. As for the greatest difficulty after employment, 31.1% of the subjects indicated the confliction among employees from variouatiolleges, 27.3% uncertainty of duties related to es of major, 24.9% bmrdens of self-development.

스테레오 정합 방법은 2차원 영상으로부터 깊이정보를 얻는 여러 가지 방법들 중 하나다. 이 방법은 서로 다른 두 시점을 갖는 스테레오 영상을 이용해 영상 속 객체 및 배경의 깊이를 예측한다. 이때 물체의 깊이 값은 한 시점의 영상 속 화소들과 다른 시점 영상에 있는 대응점들 사이의 거리 차이인 변위값에 의해 결정된다. 본 논문은 평탄한 영역 속 각 화소의 대응점을 잘 찾기 위해 거리변환을 이용한 새로운 정합비용 함수를 제안한다. 거리변환은 영상 속 각 화소가 경계 영역으로부터 얼만큼 떨어져있는지 계산해준다. 따라서 평탄한 영역에 있는 화소에 거리변환을 적용하면 특정값을 갖는 화소로 변환할 수 있기 때문에 이 영역에서의 대응점 탐색 정확도를 높일 수 있다. 또한, 정합비용을 계산하는 과정에서 1차원 배열을 이용해 영상의 영역별 특성에 따라 정합 방법이 적응적으로 적용되도록 한다. 최적의 대응점을 찾기 위한 정합비용들의 종합 과정에는 교차 계층 구조를 이용한 종합 방법이 사용된다. 그 결과, 평탄한 영역을 포함한 모든 영역에서 기존의 방법보다 더 정확한 변위값을 얻었다.

This study was to provide basic materials to help reduce the fatigue by analyzing what effective factor the fatigue of hospital nurses in Gwangju and Jeonnam region. and what causes their fatigue. This descriptive research by Questionaires includes two hospitals in Gwangju. and seven hospitals in Jeonnam region, total 9 hospitals sampled at convenience sampling. The periods of collecting data was from Jul.22, 2002 to Jul. 30, 2002. Multidimensional Fatigue Scale; MFS, developed by Jang Se-Jin(2000) was taken to measure the fatigue. All collected materials were got the statistics by SAS for Windows Release 8.01. The result of this study was as follows. 1. This study included total 740 nurses, whose age ranged from 22 to 50; 30 years old by average. Nurses fatigue mean score was 90.24 (the scope by the measuring instrument is 19-133). Nurses at University Hospitals marked 92.36 and those at General Hospitals marked 87.91 in the mean score of fatigue. 2. They kept tired at work, and felt more tired while working at computer in the hospital. 3. The part of body in which they felt fatigue was the calf and $feet(36.6\%)$, the shoulders and back of the $neck(30.7\%)$, and the whole $body(10.8\%)$ and the reason that they felt tired at work was mental $stress(33.0\%)$, overworking(25.2\%)$, and irregular working $conditions(14.7\%)$ in order. 4. The solution to their fatigue at work appeared nothing by $50.1\%$, and the way of releasing fatigue after work indicated getting some $sleep(30.8\%)$, and taking a bath or a $shower(21.7\%)$ in order. 5. The degree of fatigue depending on whether they were satisfied with their pay and labor condition appeared low: and when they were satisfied with doctors. and when they were getting on well with caregivers. 6. The effective factor of the degree of fatigue appeared: the influence that fatigue in the hospital makes on daily life was $10.6\%$, the cause of fatigue at work, $9.3\%$, time of fatigue at work, $7.8\%$, the relationship with caregivers, $5.3\%$. and these explanatory$(R^2)$ variables.$33\%$. To conclude. the degree of nurses' fatigue appeared high. and it was higher in nurses at University Hospitals than in ones at General Hospitals. In addition, the influence that fatigue from the hospitals made on daily life was the most explanatory.
