대다수의 증산계 종단들은 증산의 종교사상이 단군사상을 그대로 재현한 것이라는 주장을 펼쳐왔다. 그러나 증산계 종단 가운데 거의 유일하게 대순진리회만큼은 1909년 종단 초기부터 지금까지 줄곧 단군과 일정한 거리를 유지하고 있다. 대순진리회의 신앙 대상이나 교리체계 그 어디에도 단군의 흔적은 발견되지 않는다. 단군에 대한 대순진리회와 타 증산계 종단들의 입장이 다른 이유를 찾기 위한 하나의 방편으로 이 글은 대순사상과 단군사상이 서로 연결될 수 있는지, 그 가능성을 검토해 본 것이다. 구체적으로는 대순사상과 단군사상의 서사구조와 모티프를 비교 분석한 것이 이 글의 핵심 내용이다. 사실 증산께서는 단군에 대해 별다른 언급을 하신 적이 없으셨다. 그러므로 증산 화천 후 해방 이전까지는 대순진리회를 포함한 모든 증산계 종단들이 단군사상에 주목하지도 않았고 단군을 신앙의 대상 가운데 하나로 여기지도 않았다. 해방 이후가 되면 한국사회에 민족의 구심점으로 단군이 크게 대두되고, 단군을 중심으로 한국인이 하나로 뭉쳐야 한다는 단군민족주의가 사회에 막대한 영향을 미치기 시작했다. 거의 모든 증산계 종단들은 거기에 편승하여 그들의 신앙과 교리를 변용시켰다. 명백히 그것은 시류를 이용하여 포교에 도움을 얻고자 했기 때문이었다. 오직 대순진리회만큼은 교조의 가르침이 아니므로 단군민족주의를 받아들이지 않았다. 또한 사상적인 측면에서도 유사점보다는 차이점을 더 많이 갖고 있다. 이상과 같은 이유로 해서 대순진리회는 단군을 교리나 신앙 체계에 채택하고 있지 않다고 생각된다.

Pb2+ ino, added in ctching sohing, is electrodeposited on a alumiunm foil for electrolycic condenser to promote its capacitance. In addition, several factoral factors in etching process are varied to examine how they change the capacitance of the condenser. The capacitance of the condenser made of 0.1 ppm pb electrodeposited aluminum foil is enhanced about 20% than of conventional ane. It is thought out that the enhanement is the result of the act of PbO2, which existed for the conveting of electrodeposited Pb, as a promoter tunnel etching of aluminum foil.

이 연구는 계절 변화에 대한 초등학생들과 벨리즈 초등교사의 선개념을 조사하고 계절 변화의 원인을 이해하는데 도움이 되는 실험을 고안한 것이다. 계절 변화에 대한 선개념을 알아보기 위해 계절변화를 학습하지 않은 초등학교 6학년 91명의 학생과 벨리즈 초등교사 10명을 대상으로 개방형 질문지와 인터뷰를 실시하였으며, 귀납적 분석법을 이용하여 범주화하였다. 초등학생과 벨리즈 초등교사는 계절 변화의 원인을 지구의 자전, 태양과 지구 사이의 거리, 지구의 공전, 환경오염이나 기후변화 등으로 생각하고 있었다. 그리고 이러한 오개념은 공간 인식에 대한 어려움, 교과서나 교재의 부정확함 등에 기인하는 것으로 나타났다. 계절 변화에 대한 부정확한 선개념을 바로 잡고 계절 변화 수업을 개선하기 위하여 지구 자전축의 기울기에 따른 태양의 남중 고도와 낮과 밤의 길이를 측정하고, 이를 비교하는 실험을 고안하였다. 이 실험은 태양의 남중 고도와 낮의 길이 변화와 같은 자연 현상을 모형을 통해 측정할 수 있도록 하여 계절변화의 원인을 이해하는데 도움을 줄 수 있다.

The amount of Pinus rigida pollen deposition was hourly measured by Durhan's pollen trap in Seoul National University during May 9∼16 o'clock and 9∼15, 1988. The peak times or pollen deposition were 9∼10 o'clock and 16∼17 o'clock. The correlation coefficients between pollen deposition and mean temperature, relative humidity, and wind speed were 0.625, -0.655 and 0.418 respectively, It is thought that pollen maturation rate is correlated with mean temperature and the pollen deposition with increasing wind speed.

In many industrial experiments, some practical constraints often force factors in an experiment to be much harder to change than others. Such an experiment involves randomization restrictions and it can be thought of as split-plot experiment. This paper investigates the path of steepest ascent/descent within a split-plot structure. A method is proposed for calculating the coordinates along the path.

In this paper, the 2-phase excitation method is proposed to reduce vibration and noise. This excitation method produces reluctance torque by mutual action between two phases as well as conventional-reluctance torque due to two phases excitation at a time. The vibration and acoustic noise is reduced thought the sequential phase excitation. This is because that the scheme reduces abrupt change of excitation level by distributed. balanced excitation.

Gojong(高宗) had experienced extravagant change during a period of reign and he was located in the center of the change. He was the king who also experienced various changes in construction and accomplished a large number of construction activities aggressively. Gojong could acquire the information and details about anarchitecture, through the experience of a lot of large-scale construction activities in a regency period of Heungseon-Daewongun(興宣大院君). After opening of a port, as the western culture and technology was flowed in Korea, the knowledge of western architecture also was introduced. Gwanmungak(觀文閣) was constructed in Kyeongbokgung Palace under that influence in 1888, but the construction was not successfully finished. Due to the failure of Gwanmungak, Gojong no more constructed a western architecture until 1897. He was aware of the merits of western architectures while living in the western architecture during Agwanpacheon(俄館播遷). And he led a lot of constructions of the western architectures in Kyeongungung(慶運宮). It is possible to arrange in two reasons about the interest in an architecture of Gojong. Firstly, Gojong was individually interested in the architectures, and he constantly accomplished constructions of new buildings from childhood. And secondly, Gojong thought that western architecture has an advantage in the international situations. He held out the tendencies to construct the western architectures with excessive investments.

The study was designed to investigate the effects of Palmul-Tang(PMT) on the change of cerebral hemodynamics [regional cerebral blood flow(rCBF), pial arterial diameter(PAD) and mean arterial blood pressure(MABP)] in normal and cerebral ischemic rats. The change of rCBF and MABP were determinated by laser-doppler flowmetry(LDF), and the change of PAD was determinated by video-microscopy. The results in normal rats were as follows ; PMT significantly increased rCBF and PAD in a dose-dependent, and PMT increased MABP in a dose-dependent. This results were suggested that PMT significantly increased rCBF by dilating PAD. The results in cerebral ischemic rats were as follows ; Both rCBF and PAD were significantly and stably increased by PMT(10㎎/㎏, i.p.) during the period of cerebral reperfusion, which contrasted with the findings of rapid and marked increase in control group. The present authors thought that PMT had an anti-ischemic effect through the improvement of cerebral hemodynamics.

Objectives : The electroacupuncture was generally has been used in oriental medicine doctors. In recent years, there have been a few studies about safety and stability of acupuncture needle in itself, but then again research of acupuncture needle safety and stability on applying electroacupuncture have been insignificant. Therefore we investigated the safety and change in mechanical characteristic of acupuncture needle in electroacupuncture therapy. Methods : We observed mechanical characteristic change by SEM(Scanning Electron Microscope) and EDX(Energy Dispersive X-ray Spectroscopy), evaluated the hardness by vickers hardness tester. We used MTT assay and cell stain to study about biocompatibility of electroacupuncture. Results : In this study, any corrosion of material, alternation of elements, and change of hardness were not observed in surface analysis using SEM and EDX. In cytotoxity evaluation using MTT assay and cell stain, cell survival rate was low when practicing the electroacupuncture for more than 3 hours. Conclusions : Change of mechanical property was not observed based on the test results using surface analysis and hardness estimation by the electroacupuncture. And considering the biocompatibility, electroacupuncture was thought to be safe in an hour based on cytotoxity evaluation using MTT assay and cell stain.

Urban regeneration, which implies a certain type of change from what has previously existed, requires fundamental understandings of previous problematic ways of thinking for a meaningful change, as well as a new philosophy that is thought to support that change. This means a change in philosophy is needed to discuss 'newness' in urban regeneration. From this perspective, this paper explores the philosophies which shaped traditional cities as well as a philosophy that may be able to suggest changes to contemporary cities. This paper further proposes contextual novelty as necessary to pursue. This contextual novelty does not deny modern cities' problems but embraces them and carries them into contemporary cities. Arguing for qualitative novelty, this paper argues that contextualism, which explores the complex relationships of direct and indirect contributors of a given event, can help us to understand contemporary cities' heterogenic characteristics. In this context, this paper discusses the concept of novelty in contemporary discourse of urban regeneration by using the philosophy of contextualism. Finally a recent example of urban regeneration in the city of Gwangju, South Korea is interpreted using the concept of contextual novelty.
