적혈구 침강속도에 대한 Westergren tube 각도, 온도 및 NaCl 농도가 미치는 영향

김도균,김영홍,유창준,Kim, Do-kyun,Kim, Young-hong,Yu, Chang-jun 대한수의학회 1996 大韓獸醫學會誌 Vol.36 No.1

Erythrocyte sedimentation rate is influenced by plasma protein, red cell itself and physiological conditions and it is clear that the measurement of erythrocyte sedimentation rate varies with technique and various environmental factors. The effect of temperature, angle of test tube, and osmobility with different percent of NaCl solution on erythrocyte sedimentation rate on sheep was determined by modified Westergren method. In sheep, as the angle of Westergren tube was decreased from $90^{\circ}$ to $45^{\circ}$, erythrocyte sedimentation rate was increased in both diluted plasma and NaCl solutions. As temperature was increased from $4^{\circ}C$ to $20^{\circ}C$ at $45^{\circ}$ angle. erythrocyte sedimentation rate was increased. In ruminants, this modified Westergren methods, erythrocyte 1 : plasma 9 instead of erythrocyte 4 : plasma 6(whole blood), enable them to have meanings as dog therefor, using this method, clinical can determine the erythrocyte sedimentation rate of ruminants for diagnosis. Because erythrocyte sedimentation rate was changed according to the angle of Westergren tube, temperature as erythrocyte diluted with NaCl, this study detected that the change of temperature, the angle of Westergren tube could change erythrocyte sedimentation rate by effecting red cell itself. The increase of osmobility owing to change of NaCl percent resulted in the decrease of rapid erythrocyte sedimentation rate. So this fact indicate that deformibility and the change of red cell volume have meaning in the change of erythrocyte sedimentation rate.

마찰대전을 이용한 정전분리는 서로 상이한 물질간의 마찰을 통해 서로 다른 극성으로 하전시켜 이를 전기장내에 통과시켜 분리하는 기술이며, 플라스틱과 같은 부도체입자들의 정전분리에 많이 사용된다. 본 연구에서는 연속식 드럼형 마찰대전장치를 개발하고 이를 폐건축 및 폐가전 플라스틱의분리에 적용시켰다 분리대상 플라스틱은 폐건축 자재의 경우 PE/PVC 혼합시료를 대상으로 하였으며, 폐가전의 경우 ABS/PS/PP의 혼합시료를 대상으로 하였다. 건축자재 혼합플라스틱 및 가전제품 혼합플라스틱 모두 드럼형 마찰대전장치를 이용할 경우 실험한 조건에서 무게기준으로 95%이상의 순도조건에서 95%이상의 회수율을 보였다. Triboelectrostatic separation process is a technology that different particles charged after contact and rubbing different materials are separated in a high electric field. This technology has an advantage in that it can be used for separating non-conducting materials such as plastics unlike other electrostatic separation processes. There are two objectives in this study. One is to develop an effective continuous tribo-electrostatic separation process. The other is to apply the developed device for the separation of mixed plastics. Results show that almost all tested plastics reaches over 95% in yield and grade after separation.

Introduction: Although several types of calcium-phosphate coumpound have been frequently applied to osseous defects at maxillofacial area for many years, there is a controversy about its efficiency on bone conductivity comprared to xenograft bone substitute. Alloplastic carbonapatite has been introduced to improve disadvantages of hydroxyapatite and to mimic natural bone containing carbon elements. However, a preclinical study about its efficiency of osteoconductivity has not been reported. This study was performed to evaluate the early osteoconductive potential of synthetic carbonapatite with multiple pores relative to anorganic bovine xenograft. Materials and methods: Total 5 beagle dogs were used for maxillary augmentation model. The control (anorganic bovine xenograft) and experimental groups (synthetic carbonapatite) were randomly distributed in the mouth split design. After bone graft, all animals were sacrificed 4 weeks after surgery. Histological specimens with Masson Trichrome staining were made and histomorphometrically analysed with image analyser. The statistical analysis was performed using paired t-test. Results: In both groups, all animals had no complications. The experimental group showed relatively much new bone formation around and along the bone substitutes, whereas it was clearly reduced in the control group. The ratios of new bone area to total area, to material area and to the residual area excluding materials were higher in the experimental group ($0.13{\pm}0.03,\;0.40{\pm}0.13,\;0.20{\pm}0.06$ respectively) than in the control group ($0.01{\pm}0.01,\;0.03{\pm}0.02,\;0.03{\pm}0.03$, respectively). And the differences between both groups were statistically significant (p<0.001, <0.01, <0.01, respectively), while the ratio of material area to total area in two groups was not significant. Conclusion: Carbonapatite showed a high osteoconductivity in the early stage of bone healing compared to bovine derived anorganic bone substitute. This study suggests that this bone materials can be applied as a reliable bone substitute in the clinical treatment.

김도균,추호성,Kim, Do-Kyun,Choo, Ho-Sung 한국전자파학회 2007 한국전자파학회논문지 Vol.18 No.4

본 논문에서는 부착될 물질이 가지는 전기적 특성에 의한 성능 변화가 적은 이중 선로의 비대칭 다이폴 형태 RFID 용도 태그 안테나(Asymmetric Dual-arm Dipole Antenna: ADDA)를 제안하였다. 제안된 태그 안테나는 상용 의료 폐기물 수거용 플라스틱 밀폐 용기(${\varepsilon}_r=1.7,\;tan\;{\delta}=0.002$)에 부착하여도 안테나의 동작 특성 변화가 적도록 설계되었다. 안테나의 세부적인 설계변수는 자유공간과 인식 대상 물체에 부착시 우수한 인식거리 성능을 나타내도록 Pareto 유전자 알고리즘을 사용하여 최적화하였다. 최적화 태그 안테나는 $100\;mm{\times}50\;mm$의 크기를 가지며, 3.7 %의 반사 손실 대역폭($S_{11}$< -10 dB)을 가지고 80 %의 복사효율을 나타내었다. 인식 거리 측정 결과, 자유공간에서 정면 방향(broadside) 5.3 m, 의료 폐기물 수거용 플라스틱 밀폐 용기에 부착시 최대 5.5 m의 인식거리 성능을 가지는 것을 확인하였다. In this paper we proposed the tag antenna with a low performance distortion from an attached surface material using the asymmetric dual-arm dipole antenna(ADDA) structure. The tag is designed to exhibit low performance changes when the tag is attached on a target object(the medical litter receptacle, ${\varepsilon}_r=1.7,\;tan\;{\delta}=0.002$). Detail design parameters for the proposed antenna are optimized to maintain a good readable range in free-space as well as on a target object. The size of the optimized antenna is $100\;mm{\times}50\;mm$. The antenna shows the matching bandwidth($S_{11}$< -10 dB) of 3.7 % and the radiation efficiency of 80 % at the operating frequency. Finally we confirmed the readable range of the tag antenna by measurement and it shows about 5.3 m in free space and 5.5 m on the target object.

김도균(Do Kyun Kim),이재혁(Jae Hyuck Lee),서은주(Eun Ju Seo) 한국환경사회학회 2021 환경사회학연구 ECO Vol.25 No.1

본 연구의 목적은 한국사회에 적합한 환경오염의 피해양상 및 복구과정을 분석할 수 있는 ‘환경오염피해의 사회모델’을 개발하는 데 있다. 환경오염피해의 사회모델을 제안하기 위해 사회영향평가, 피해의 사회구조론, 재난복원력, 기술재난 등에 관한 이론적 수준의 연구뿐 아니라 국내의 사회학, 인류학 분야에서 수행된 다양한 경험적 연구를 검토하고 분석했다. 그 결과 환경오염피해를 종합적으로 이해하기 위한 세 개의 경로(분석틀)와 경제영역, 사회영향, 건강영역, 생명영역으로 구성된 28개의 오염피해 평가변수, 복구과정에서의 주요 변수들을 제안했다. 또한 변수를 평가(조사)함에 있어 오염피해자의 입장이 잘 전달될 수 있는 조사방법을 활용할 것, 그리고 오염피해자의 의견을 존중하는 피해자 중심주의 관점에서 평가가 이루어져야 한다는 점을 강조했다. The research objective is to develop “a model of society with environmental pollution damage” that can be used for analyzing various types of damage caused by environmental pollution as well as the rehabilitation process. To suggest “a model of society with environmental pollution damage”, this study utilized various previous studies from the fields of sociology and anthropology, along with theoretical studies on social impact assessment, social structure of damage, disaster resilience, and technical disaster. As a result, we suggested 28 variables consists of three pathways to comprehensively understand the pollution damage resulting from an environmental pollution accident, economic area, social impact, and health and life area. And we also stressed that in evaluating(investigating) variables assessment should actively utilized by adopting the method that can convey the standpoint of the victims, and evaluation should be made from a victim-centered perspective that respects the opinions of the contaminated victims.

87년 민주화 이후 충청지역시민운동의 제도화

김도균(Do Kyun Kim) 충남대학교 사회과학연구소 2015 사회과학연구 Vol.26 No.1

사회운동 혹은 사회운동조직이 그 사회의 확립된 제도 틀 안에서 운동자원을 동원하고, 운동의 목표를 달성하는 방향으로 변화하는 과정을 사회운동의 제도화라고 한다면, 충청지역을 대표하는 권익주창NGO인 대전참여자치시민연대와 충북참여자치시민연대는 창립초기부터 현재까지 적극적으로 제도화 경로를 선택했다고 볼 수 있다. 운동조직의 제도화라고 할 수 있는 내적 제도화 과정은 지속적인 회원 및 재정 증대를 통해서 확인할 수 있었다. 회원 증대를 위하여 두 단체 모두 회원 관리의 전산화와 함께 회원 및 시민서비스개념을 적극적으로 도입하였다. 재정 증대를 위해서는 CMS라는 전문화된 프로그램을 도입하였고 정기적으로 후원행사를 진행하였다. 운동의 제도화라고 할 수 있는 외적 제도화 과정은 운동이슈와 운동레퍼토리, 제도적 의사결정과정의 참여 등을 통해서 확인할 수 있었다. 두 단체 모두 종합적 시민운동을 지향해왔기 때문에 다양한 운동이슈를 다루어왔다. 하지만 두 단체가 주로 다룬 지역운동이슈들은 정치적 권위에 직접적인 위협을 가하지 않았으며 제도개선을 통한 문제해결 방식을 선호했다. 그리고 운동레퍼토리 또한 활동 초기부터 일관되게 관례적 레퍼토리가 지배적이었다. 즉 충청지역에서 활동해 온 두 참여연대는 사회제도 밖에서의 저항전략보다는 사회제도 안에서의 저항전략을 추구해왔다고 결론 내릴 수 있다. If the process that either a social movement or social movement organization mobilizes movement resources within the society’s established frame of systems and changes to the direction to attain the goals of movement is ‘the institutionalization of social movement’, DPSPDS and CSPAC which are Advocacy NGOs representing Chungcheong can be regarded that they have chosen the paths of institutionalization aggressively from the initial period of foundation until now. The internal process of institutionalization that can be said to the institutionalization of a movement organization can be found through the activities of the two groups to increase their members and finances. To increase members, the two groups introduced not only the computerization of member management but member and civil service concepts positively. To increase finances, they induced a specialized program called CMS and held supporting events regularly. The external institutionalization process that can be regarded to be the institutionalization of movement can be found through movement issues, movement repertoires, or systemic participation in the decision-making process. As the two groups both have pursued general civic movements, they have dealt with various movement issues. However, regional movement issues mainly dealt with by the two groups did not give direct threat to the political authority but preferred problem-solving through system improvement. In addition, about movement repertoires, too, consistently conventional repertoires have been dominant from the initial period of activity. In other words, it can be concluded that the two PSPDs in Chungcheong have pursued resistance strategies not outside but inside the social system.

대전지역 사회운동의 성장과 분화: 거대한 운동에서 차이의 운동들로

김도균 ( Do Kyun Kim ) 한양대학교 제3섹터연구소 2016 시민사회와 NGO Vol.14 No.1

대전지역 사회운동의 성장과 분화과정은 한국 사회운동의 일반적 궤적과 유사한 경로를 보였다. 87년 이전부터 종교·학생·교육·문화·청년운동 등 여러 사회운동세력이 존재했지만, 반독재민주화운동이라는 거대한 운동으로 수렴되어 있었다. 개별 운동세력들은 자신들의 독자적인 정체성을 강조하기 보다는 오히려 각 부문운동을 통해 반독재민주화운동을 강화하는 전략을 선택하였다. 87년 6월 항쟁 이후에서야 대전지역에서도 본격적으로 노동운동과 시민운동의 1차 분화가 이루어졌다. 이후 지속해서 2차 분화가 진행되면서 ``거대한 운동에서 차이의 운동들``로 지역사회운동의 지형도가 재구조화 되었다. 지역사회운동의 성장과 분화에 있어 90년대에 도입되고 확대된 지방자치라는 새로운 정치제도가 중요한 영향을 미쳤다. 즉 지역정부와 지역시민운동이라는 새로운 정치구도는 지역사회운동의 생성과 확장을 자극하였다. 90년대 들어 새롭게 생성된 정치경제개혁운동, 여성운동, 환경운동뿐만 아니라 2000년대에 들어 새롭게 부상한 대안사회운동 및 풀뿌리운동들 또한 지방화 시대를 맞아 지역사회를 진보적·민주적·합리적·호혜적으로 재구성하려는 지역사회운동의 능동적 자기 진화의 과정이라고 할 수 있다. The growth and diversification process of social movements in Daejeon showed conventional track records and similar paths of Korean social movements. Various social movement powers, religious, student, educational, cultural and youth, had existed before 1987, but they were converged as a big movement called "anti-despotic pro-democracy movement." Each movement chose a strategy to expand anti-despotic pro-democracy movements through each sector, rather than to strengthen its own identity. It was only after the strife in June, 19878 when the first differentiation between labor movements and civil movements took place. And, it continued to the second differentiation when the topography of community movements was restructured "from a big movement to many movements with differences." In the growth and differentiation of community movements, a new political system called local self-government, which was first introduced in the ``90s and expanded, had an important influence. This new political structure generated by a local government and local civil moments stimulated the birth and expansion of community movements. It can be said that facing the age of local self-government, not only political and economic reform movement, women``s movements and environment movements that newly arose in the ``90s but also alternative society movement and grassroots movements that newly emerged in the 2000s were to restructure a local community in progressive, democratic, rational and mutually beneficial manners, or it was a process of active self-evolution of community movements.
