Observations of line of sight (LOS) Doppler velocity and non-thermal line width in the o-limb solar corona are often used for investigating the Alfven wave signatures in the corona. In this study, we compare LOS Doppler velocities and non-thermal line widths obtained simultaneously from two dierent instruments, Coronal Multichannel Polarimeter (CoMP) and Hinode/EUV Imaging Spectrometer (EIS), on various o-limb coronal regions: aring and quiescent active regions, equatorial quiet region, and polar prominence and plume regions observed in 2012{2014. CoMP provides the polarization at the Fe xiii 10747 A coronal forbidden lines which allows their spectral line intensity, LOS Doppler velocity, and line width to be measured with a low spectral resolution of 1.2 A in 2-D o limb corona between 1.05 and 1.40 RSun, while Hinode/EIS gives us the EUV spectral information with a high spectral resolution (0.025 A) in a limited eld of view raster scan. In order to compare them, we make pseudo raster scan CoMP maps using information of each EIS scan slit time and position. We compare the CoMP and EIS spectroscopic maps by visual inspection, and examine their pixel to pixel correlations and percentages of pixel numbers satisfying the condition that the dierences between CoMP and EIS spectroscopic quantities are within the EIS measurement accuracy: 3 kms􀀀1 for LOS Doppler velocity and 9 kms􀀀1 for non-thermal width. The main results are summarized as follows. By comparing CoMP and EIS Doppler velocity distributions, we nd that they are consistent with each other overall in the active regions and equatorial quiet region (0.25  CC  0.7), while they are partially similar to each other in the overlying loops of prominences and near the bottom of the polar plume (0.02  CC  0.18). CoMP Doppler velocities are consistent with the EIS ones within the EIS measurement accuracy in most regions ( 87% of pixels) except for the polar region (45% of pixels). We nd that CoMP and EIS non-thermal width distributions are similar overall in the active regions (0.06  CC  0.61), while they seem to be dierent in the others (􀀀0:1  CC  0.00). CoMP non-thermal widths are similar to EIS ones within the EIS measurement accuracy in a quiescent active region (79% of pixels), while they do not match in the other regions ( 61% of pixels); the CoMP observations tend to underestimate the widths by about 20% to 40% compared to the EIS ones. Our results demonstrate that CoMP observations can provide reliable 2-D LOS Doppler velocity distributions on active regions and might provide their non-thermal width distributions.

Urban sanitary sewer systems can aid in preventing inundation, and can improve civil health by effectively disposing stormwater and wastewater. However, since sewage odor can cause adverse effects, numerous technical and administrative studies have been conducted for reducing such odor. European countries and the United States of America (USA) built modern sewer systems in the late 19th century, and have since been endeavoring to eliminate sewage odors. Several cities of the USA, such as Los Angeles (LA) that has a separate sewer system and San Francisco (SF) that has a combined sewer system, have produced and distributed odor control master plan manuals. Features common in the odor reduction plans of both these cities are that the odor reduction programs are operated in all the respective local regions and are supported by administrative systems. The primary aspectual difference between the two said programs is that the city of LA employs a sewage air purification system, whereas the city of SF controls the emission of major odor causing compounds. Compared to the existing sewer odor reduction systems of these two cities, South Korea is still in the initial phase of development. Through technical studies and policy implementations for sewer odor reduction, a foundation can be laid for improving the civil health quality.

우리나라의 경제성장의 견인차 역할을 담당해왔던 산업단지는 착공 후 30년이 경과하면서 노후화되고 이로 인해 그 역할을 수행하는데 한계에 봉착해오고 있다. 낮은 도로율과 불법주차, 그리고 교통사고 등으로 도로 인프라로써의 제 기능을 효율적으로 수행하기에는 해결해야할 요인이 다수 존재한다. 따라서 본 연구는 산업단지 경계 내 존재하는 도시부 도로의 효율성 극대화를 도모하기 위하여 운영과 안전측면에서의 효율성을 종합적으로 판단하기 위한 LOS 분석기법을 제시하고, 이를 통해 우리나라 노후산업단지 도시부 도로를 평가하여 향후 도로 인프라 성능을 상향시킬 수 있는 방안을 모색하고자 하였다. 산업단지 내 만성적인 불법주차가 운영 LOS에 미치는 영향을 파악하기 위한 민감도 분석과 함께, 안전 LOS분석을 위해서 전체 산단 혹은 도로축에 적용할 수 있는 위험도 산정식을 개발하여 분석에 활용하였다. 사례 분석을 위하여 산업단지의 규모와 도심과의 거리 등을 고려한 5개 산업단지를 선정하였고, 운영과 안전 LOS를 종합적으로 분석한 결과를 도출하였다.

Since aged water treatment facilities could threaten the sustainable water supply, asset management system has been adopted for their systematic management. Level of Service(LoS) is one of critical components of asset management and could be quantified through benchmark index(BMI). Water supplier could estimate consumer’s satisfaction and their performance through BMI to improve the LoS. We developed BMI for water treatment facilities from customer’s satisfaction survey. BMI, represented with the Total Service Score(TSS), was assessed with water quality, water pressure, taste and odor, water rate, and service quality with weighing factors. BMI could, further, be used to assist the analysis of the life cycle cost to increase the unit of LoS.

The function failure of present major facilities is likely to lead to failure of related systems and/or whole facilities, increasing the necessity for protection of infrastructures, main structures, and major industrial facilities. In addition, safe and efficient management for urban infrastructure (waterworks and sewerage facilities, electricity, telecommunications, roads, etc) installed in the basement or on large cities grounds at various public areas is required. Recently in response to this demand, efforts for vitalizing asset management are being made such as enacting related laws and developing asset management system in the U.S., Australia, Europe and other advanced countries with the concept for a new maintenance. In our county, identifying maintenance system problems such as aging and rapid increasing of existing infrastructures and decision-making about updating maintenance is required for systematic and organizational maintenance. In this study, by comparing and observing the LOS(Level of Service) of each countries’ waterworks and risk-based LOS, we suggest the direction of future urban water infrastructure management systems for more effective management.

PURPOSES: This paper aims at the implementation of a balanced scorecard that can be widely applied to modern business management for use in the public road management sector. METHODS: This study applied the newly developed LOS-based balanced scorecard system instead of a traditional Key Performance Index (KPI) for better decision making in asset management planning. As an evaluation technique, a“ hierarchical alignment and cascading method” is also suggested. Finally, the suggested system has been empirically applied to a regional government. RESULTS : To provide stable and sustainable road services, the balanced scorecard informs the regional government of needed improvements in its asset management plans regarding budget optimization, structural management, the development of inner-business processes, and human resources. CONCLUSIONS : An LOS-based balanced scorecard for managing road services and organizations in a quantitative manner has been successfully developed and tested through a field study. The developed scorecard is a timely topic and a useful analytical tool for coping with the new phases of an aging infrastructure, tighter budgets, and demand for greater public accountability.

1799 Francisco de Goya published Los Caprichos with 80 aquatint etchings. On 6 February he advertised it on the front page of the Diario de Madrid. The long advertisement which began with "a collection of prints of capricious subjects, invented and etched by Don Francisco Goya" informed purpose, themes and methods of this collection of prints. According to this advertisement Goya "has chosen as subjects for his work, from the multitude of follies and mistakes common in every civil society and from the vulgar prejudices and lies authorized by custom, ignorance or self-interest, those that he has thought most fit to provide material for ridicules, and at the same time to exercise the artist's imagination." The text emphasized that the 'author' of this series didn't to want to criticise any individual and to be a copyist. From his phantasy Goya invented many creatures like the anthropic, humanized animals etc.. With Los Caprichos he stood on the threshold to Romanticism. The early researchers of Los Caprichos classified its author, Goya as an enlightened intellectual. The similarity of the themes of the series with the subjects of the Enlightenment, his some enlightened 'friends' and the idea to avoid the prevalent mystification of his life supported this theory. But this trend became revised since the 80's of the last century. This made possible to research Goya's works in new perspective and to see that Goya didn't criticise the Spanish society and his contemporaries. Rather he showed its reality and parodied through creatures which are mixtures of the reality that he observed, and visions that he invented. Characters and scenes in Goya's prints are ambiguous and equivocal. They have the values which are defined by the dualistic metaphysic in Europe as oppositional, like good and evil for example, at the same time. Goya himself also appeared in various types in this series. This ambiguousness, or "polyphony", as Jennis Tomlinson defined, is a symptom of the decay of the belief in the Enlightenment which spreaded in Europe as a result of the attack of Bastille and the French Revolution. Goya's self-portrait in pl. 43 of this series, "El sueño de la razon produce monstruos" shows the complex psychology of him and his contemporaries as well. As the rest etchings after this print show witchcraft and monsters reside in the world in which the reason of the Enlightenment and the through the reason weakened God's rule lost their authority. In this thesis I will examine and analyse how Goya represented in Los Caprichos the nature of man and its society, as complex being in which the 'antagonistic' value couple as good and evil couldn't be divided, but are united.

본 연구는 비디오영상에 의한 간접설문조사방식을 통하여 도시부 간선도로의 운전자들이 주행 시 느끼는 인식서비스수준과 도로용량편람(KHCM)에 의해 산정된 실제서비스수준간의 차이를 확인하고, 운전자가 인식하는 서비스수준에 영향을 미치는 주요요인을 규명하는 것이다. 본 연구의 주요 연구결과를 요약하면, 첫째, 실제서비스수준과 인식서비스수준간의 인식률 차이를 검증한 결과, 신호교차로구간의 경우 40.8%, Mid-block구간의 경우 59.2%가 두 서비스수준을 동일하게 인식하는 것으로 나타났다. 또한 두 서비스수준간의 동질성 검정(F통계검정, t통계검정)결과에서도 두 서비스수준 간의 차이가 뚜렷이 나타났다. 둘째, 신호교차로구간에서 인식서비스수준에 영향을 미치는 요인으로 교통류(26.4%), 신호운영(23.1%), 기하구조(18.1%), 이용행태(15.9%) 도로경관(10.0%), 유지관리(4.4%), 교통정보(2.2%) 요인을 순서대로 고려하여 결정하는 것으로 분석되었으며, 이중 교통류 등 상위 3개 요인이 정량적 요인으로 67%를, 이용행태, 도로경관요인과 같은 정성적 요인이 26%를 점유하고 있는 것으로 나타났다. 셋째, Mid-block구간에서 인식서비스수준에 영향을 미치는 요인으로 기하구조(25.3%), 경관(20.0%), 신호운영(19.2%), 교통류(15.3%), 이용행태(9.7%), 유지관리(6.4%) 교통정보(4.2%)순으로 분석되었으며, 특히 이중에서 정성적 요인에 해당하는 도로경관이 신호교차로구간 10.6%보다 높은 20.0%로 많은 영향을 미치는 것으로 나타났다. 따라서 향후 서비스수준 산정을 위한 분석 시에는 운전자가 실질적으로 인식하는 정성적인 요인 (이용행태, 도로경관 등)을 고려하는 것이 필요하다고 판단된다.

Decreased equilibrium in standing and walking is a common problem associated with hemiparesis secondary to cerebral vascular accident. In patients with hemiplegia, postural sway is increased and often displaced laterally over the non-affected leg, reflecting asymmetry in lower extremity weight bearing during standing balance. Human balance is a complex motor control task, requiring integration of sensory information, neural processing, and biomechanical factors. Limits of stability (LOS) is a one of the biomechanical factors. The purposes of this study were to establish the influence of asymmetrical weight-bearing on the LOS of independent ambulatory hemiparetic patients. The subjects of this study were 29 hemiparetic patients (18 males, 11 females) being treated as admitted or out patients at Young-Nam University Hospital and Taegu Catholic University Hospital, all of whom agreed to participate in the study. Participants were asked to lean and displace their center of gravity (COG) as far as possible in directions to the sides and front of the body. The LOS and weight-bearing ratio were measured with a Balance Performance Monitor (BPM) Dataprint Software Version 5.3. In order to assure the statistical significance of the results, the independent t-test and a Pearson's correlation were applied at the .05 and .01 level of significance. The results of this study were as follows: 1) There were statistically significant differences in anteroposterior LOS according to the cause of brain demage (p<.01). 2) There were statistically significant differences in mediolateral LOS according to the hemiparetic side (p<.05). 3) There were statistically significant differences in anteroposterior and mediolateral LOS according to the brain operation (p<.01). 4) The mediolateral LOS significantly correlated with weight-bearing ratio (p<.01).

Concentrations of fine particulate matter (PM2.5) and several of its particle constituents measured outside homes in Houston, Texas, and Los Angeles, California, were characterized using multiple regression analysis with proximity to point and mobile sources and meteorological factors as the independent variables. PM2.5 mass and the concentrations of organic carbon (OC), elemental carbon (EC), benzo-[a]-pyrene (BaP), perylene (Per), benzo-[g,h,i]-perylene (BghiP), and coronene (Cor) were examined. Negative associations of wind speed with concentrations demonstrated the effect of dilution by high wind speed. Atmospheric stability increase was associated with concentration increase. Petrochemical source proximity was included in the EC model in Houston. Area source proximity was not selected for any of the PM2.5 constituents' regression models. When the median values of the meteorological factors were used and the proximity to sources varied, the air concentrations calculated using the models for the eleven PM2.5 constituents outside the homes closest to influential highways were 1.5-15.8 fold higher than those outside homes furthest from the highway emission sources. When the median distance to the sources was used in the models, the concentrations of the PM2.5 constituents varied 2 to 82 fold, as the meteorological conditions varied over the observed range. We found different relationships between the two urban areas, illustrating the unique nature of urban sources and suggesting that localized sources need to be evaluated carefully to understand their potential contributions to PM2.5 mass and its particle constituents concentrations near residences, which influence baseline indoor air concentrations and personal exposures. The results of this study could assist in the appropriate design of monitoring networks for community-level sampling and help improve the accuracy of exposure models linking emission sources with estimated pollutant concentrations at the residential level.

This study introduces the role of level of service in the asset management for social infrastructures. An overall process to determine the level of service and performance measures were also described. The developed process was applied for actual road infrastructures, pavements, bridges and tunnels and the results were shown briefly.

지난 40여 년간 미국의 공동체 벽화는 마을의 골목길을 이야기 거리, 볼 거리로 채우면서 주민과 함께 했고 그 지역의 정체성을 대변해왔다. 특히 ‘치카노 벽화운동’은 1960년대 후반 민권운동의 예술적 기수 역할을 하였으며, 미술이 어떻게 공동체 구성원들의 의식을 변화시키고 한 국가의 문화적 정체성을 재규정해내는 데 적극 기여할 수 있는 지 보여준 사례였다. 본 연구는 생존하는 가장 대표적인 벽화가로 알려진 주디 바카(Judy Baca)의 프로젝트들을 살펴보면서, 그녀가 어떻게 민족중심적이었던 공동체 벽화를 다문화적 함의를 구현하는 작업으로 전환시켜 갔는지, 그리고 더 나아가 어떻게 초국가적인 시선으로 미술의 지평을 확장시켜 왔는지 고찰한다. 한편 학교밖 교육으로서 지역 청소년의 미술과 역사 교육에 획기적인 전례를 만들었던 <거대한 벽>의 작업 진행 방식의 특징과 의의도 짚어본다. 세계 최장(最長) 벽화인 <로스앤젤레스의 거대한 벽>(1976-1984)은 바카의 진두지휘아래 40명의 민속 사학자, 400여 명의 치카노계, 흑인계, 동양계, 백인 청소년 등이 협업하여 캘리포니아의 역사를 다양한 소수민 관점에서 그려낸 작업이다. 이는 치카노, 흑인 중심 등의 분리주의적인 민권예술운동을 종식하고 인종 간, 민족 간의 이해와 협력을 모색함으로써 다문화주의를 최초로 구현했던 기념비적인 벽화였다. 한편 바카는 그룹간 문화적 편견을 없애고 협력하여 작업하는 과정을 중요시 여겼기에, 여러 학교밖 교육적 방식을 고안하여 적용했다. 참여 학생들은 단결하여 열정적으로 그림을 그려갔고 그 후 그들이 미국의 역사적 사실에 대해 기억하는 것은 학교 수업이 아니라 <거대한 벽>을 통해서였다고 말할 정도로 이는 획기적이고 성공적이었던 프로젝트였다. 바카가 1987년 경 착수한 <세계의 벽: 공포 없는 미래를 향하여>는 초국가적 시각을 반영하는 벽화이다. 벽화의 내용은 각 국가의 특수한 역사를 재고하면서도 궁극적으로 비폭력적 저항과 인류의 화합과 균형을 지향한다는 점에서 보다 코즈모폴리터니즘적인 측면을 강조한다. 한편 이 작품은 바카가 그린 패널들이 러시아, 멕시코 등 여러 국가로 이동하면서 그 지역의 작가들이 새로 그린 패널이 부가되는 방식으로 전시되어 오고 있다. 각 지역마다 다른 내용과 작업 방식을 채택하고 있기에, <거대한 벽>만큼 참여 학생들을 위한 구체적인 교육적 방식이 적용되고 있지는 않다. 하지만 <거대한 벽>이 다양성을 인정하면서도 여전히 ‘미국적’ 정체성을 재규정하는 다문화주의적 담론을 대변한다면, <세계의 벽>은 미술을 통해 전지구적 차원에서 대화하고 교류함으로써 인종, 민족, 국가 간의 경계에 대해 질문하고 반목을 종식시키고자 하는 보다 확장적인 시도이며, 초국가주의 시대의 다문화주의가 발전해 가야할 방향을 시사해주는 사례라 할 수 있다.

본 연구는 개선된 한국형 도로용량편람 작성 작업의 일환으로 고속도로 연결로 접속부에 대한 분석방법에 관해 검토한 것으로 1992년에 작성된 우리나라의 도로용량편람(92KHCM)과 최근에 발표된 미국의 도로용량편람(USHCM2000)의 분석방법론을 비교 검토하여 국내에서의 적용가능성을 타진하고 최적의 분석방법을 정립하고자 하였다 이를 위해 본 연구의 대상구간을 설정하고 기존 방법론을 이용하여 현장 관측치와 비교 평가한 후 수집된 자료들을 분석토록 하였다. 자료의 수집 및 분석 결과 접속차로 1개만을 고려한 92KHCM의 경우 평가에 사용된 모형식에 의한 추정치와 실제 관측치가 다소 차이를 보였으나 접속차로 2개를 고려한 2000USHCM 의 경우 계산치와 관측치가 거의 일치함을 알 수 있었다. 이를 통해 2000USHCM에서의 분석방법론이 보다 합리적인 면이 많이 내포되어 있음을 확인 할 수 있었다. 또한 서비스 수준의 판정기준으로 영향권의 밀도가 사용되어 졌으며 이전의 속도에 비해 교통량의 증가에 따른 민감도가 우수함을 알 수 있었다. 본 연구에서의 분석대상 구간은 독립적인 합류부에 국한하였으나 추후 본 연구는 보다 광범위한 자료의 수집을 통해 연속적인 분류 합류 연결로 접속부에 대한 연구로 확대가 되어야 할 것으로 판단된다
