Kim,Jung-Keun 대한구강생물학회 2007 International Journal of Oral Biology Vol.32 No.4

This study was conducted to investigate the preventingeffects of OPB (Rehmannia glutinosa Libosch and Eleuth-erococcus senticosus Max extracts) and combined OPB/Calcium therapy on bone loss in ovariectomized rats. SixtySprague Dawley rats of 12-week-old were divided into eightgroups: OVX (ovariectomized), OPBL (OPB 50mg/kg),OPBM (OPB100mg/kg), OPBH (OPB 200mg/kg), OPBL/CAL(OPBL+CAL), OPBM/CAL (OPBM+CAL), OPBH/CAL (OPBH+CAL) and CAL (Calcium citrate 88.33mg/kg+1α, 25-dihydroxy-vitamin D3 33.33IU/kg). Bone mineraldensity (BMD), bone mineral content (BMC), bone strengthindices and cortical thickness were analyzed by peripheralquantitative computerized tomography (pQCT). pQCTscanning showed that OVX induced a significant decreasein trabecular bone mineral density and bone mineralcontent in the proximal tibia (-36.4±2.4%, -21.8±12.7%).These decreases were significantly prevented by theadministration of OPBM and OPBM/CAL. Cortical BMDand BMC of tibia were slightly enhanced by OPB and OPB/CAL. However there was no significant difference betweenOVX and OPB, OPB/CAL treated group. Bone strengthindices and cortical thickness were not significantly different.Our results suggest that OPB and combined OPB/Calciumtherapy are effective in preventing the development of boneloss induced by ovariectomy in rats.

인터넷을 통한 남북통일교육에 대한 소고

김종세(Kim, Jong-se) 조선대학교 법학연구원 2009 法學論叢 Vol.16 No.1

2008년 현 정부 이전의 정부가 추진해 온 남북한의 화해협력정책은 교류협력의 발전을 위한 제도적 기초를 놓았고 동시에 평화위협을 제거하는 잠정적인 성과를 거두었다. 그리고 현 정부는 화해협력정책의 연장선상에서 한반도의 평화 증진과 남북의 공동번영을 통해 평화통일의 기반을 마련하는 평화번영정책을 추진하고 있다. 특히 2000년 6월과 2007년 10월 남북한 정상회담 이후 사회적 현상으로써 인터넷에 김정일을 형상화한 캐릭터가 돌아다니는 등 예전에는 상상하기 힘든일들이 대수롭지 않아지는 계기가 되었다. 당시 이러한 관심은 인터넷을 통해 다양한 형태로 나타나면서 하나의 문화 현상을 보이기도 하였다. 이제 우리는 과거 일방적인 통일에 대한 기대와 이에 따른 통일교육도 이제 새로운 전기를 마련해야 할 것으로 판단하는데, 아직까지도 우리 사회에서 통일문제에 대해 다양한 인식과 견해들이 표출되고있다.이러한 국민들의 의식을 하나로 통합하고자 통일교육의 새로운 방안으로 우리는 인터넷 활용을 적극적으로 추진할 필요가 있다. 통일교육의 새로운 방안인 인터넷의 활용은 대중이 직접 참여함으로써 프로그램 내용의 질적 변화와 방법적 변화의 효과를 가져다 줄 수 있을 것 이다. 사이버를 활용한 통일교육은 정보화 시대에 가장 적합한 교육으로 더욱 큰 효과를 가져다 줄 것으로 본다. 즉 인터넷을 통한 통일교육은 수요자 중심의 맞춤형 교육이므로 순기능적 측면을 최대한 이용 한다면 어떠한 정보 매체보다도 가장 활용도가 높고 오늘날 이 시대에 부합하는 교육방법 중의 하나일 것이다. The policy for the South-North Conciliation and Cooperation conducted since the launch of the former president Kim’s administration laid a solid foundation for the systematic development of further exchanges and cooperation between two Koreas, and yielded tangible results of eliminating threats to peace at the same time. In addition, the current Participatory Government is driving forward with the policy for peace and prosperity, which will establish a sound basis for the peaceful Unification by promoting peace and mutual prosperity on the Korean Peninsula, extended from the policy for the South-North Conciliation and Cooperation. In this regard, it is considered that a huge transition is under way for the existing Unification education of unilateral expectations for the Unification the past. Still, the Korean society is witnessing that a variety of views and opinions are emerging on the issue of Unification. It is natural, of course, that diverse opinions are shared by citizens in a free democracy. But it is surprising that there are many who question even the validity of the Unification. This paper aims to integrate people’s awareness about the Unification into unity, and carry out a new method for the Unification education, by making the best use of broadcasting and Internet. As part of new methods of the Unification education, the broadcasting media will serve as a catalyst to make qualitative and methodological changes for the education program by facilitating the direct participation by people. I understand that the web-based Unification education is the best form for education in a new era of informatization and telecommunication. As it is a customized education devoted for users, it is my view that it will be the most appropriate educational method with the highest level of exploitation rather than any other information media.

Nonpoint source pollution(NSP) arises due to agriculture activity and it is quite an extensive and complicated problem in order to control and has received a great deal of concern during the recent years, whereas point source are known to originate from an estimated volume of contaminant discharged from a distinguishable source. Extensive research work have been conducted and presented in the past with regard to the various characteristics of watershed on Dong Jin River(DJR), however there are certain drawbacks of existing survey for determining important polluting sources, distribution features of pollutants and estimated load of the organic and nutrients from the creeks. Unfortunately, investigation for loadings originating due to agricultural drainage was not satisfactory, although the regional consideration for DJR across Kim Je Field(KJF) as an agricultural area receives a reasonable source point in the agri-pollution management. Therefore it was necessary to carry out a thorough investigation into the diffuse sources resulting, to form the pollution-developing estimation and to evaluate the output roperties and determining various factors in the generation of non-point pollution. Eventually, this research work would serve as an useful tool for the development of predictive pollution management for DJR. Non-point sources in the present work were classified as municipal non-treated sewage water discharged into the river, loadings through agricultural drainages in the dry/wet field and inadequate treatment of wastewater generated from livestocks. The entire duration of the research work was from December-2001 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined and examined during the mid of research work. Similarly, domestic wastewater loadings due to population was based on area unit, as City, Country, Up, Myon, Dong, Ri. The Dong Jin River watershed contains small three Creeks, KoBu(KB), DongJin(DJ, including JeongEup(JE) and ChilBo(CB), WonPyong(WP). It was further divided into 32 sub-watersheds which comprises of further 5,18,9 watersheds in the creeks respectively. The results obtained from research work are presented as follows. Animal productions have marked differences in the rate of pollutant loadings reported in the following sequence: DJ(only CE)>WP>CB>KB, in a case of Korean cow and milk cow. However, it was revealed that WP creek became significantly higher than any other livestocks. According to statistical data for land use, rice field(369.0㎢) and forest(378㎢) have much occupation prior to dry paddies(125.0㎢), residential land(32.0㎢) and others(5.0㎢). Especially, rice fields receives 2.5∼3 times than dry paddies in size.

『論語』에 나타난 孔子의 敎樂

김세종 全南大學校 藝術硏究所 2001 藝術論集 Vol.4 No.-

We call Confucius' teaching "Confucianism" which connotes "etiquette" and "pleasure" in parallel. "Confucianism" based on "virtue" one of the older Chinese thoughts. In " Analects of "Confucius", Confucius emphasizes the importance of learning, and in particular, praised Anja's indulgence in learning, as he believed that learning would lead to the status of his ideal or " humanization". To Confucius, therefore, teaching and learning are the soil for Confucianism. He said that "not teaching the people is the same as driving them into death". Furthermore, Confucius does not mean that what is learned should be practiced blindly. He teaches that leaning should result in finding a way to guide creativity to harmony. As an ideal method of learning, he emphasized the importance of etiquette and pleasure. Without them, the human body would be depleted of soul. Without them, the human body would not have arms and legs. Pleasure is a rhythm of human spirit, promoting the blood circulation and enlightening the spirit. Thus, Confucius tried to materialize pleasure or ecstasy by teaching "six arts": etiquette, pleasure, archery, governing of people, being fortunate and counting. In short, pleasure or ecstasy is the most ideal human emotion, and when it is guided by harmony, a most ideal humanity would be achieved. Confucius put an emphasis on the versatile whole personality who could control the historic, political, social, realistic and circumstantial changes through this harmonious learning.

본 논문에서는 양극반응과 복합 산화법( H_2O/O_2 분위기에서 500℃, 1시간 열산화와 1050℃, 2분간 RTO(Rapid Thermal Oxidation) 공정)을 이용한 두꺼운 OPSL(Oxidized Porous Silicon Layer)을 형성하여 이를 마이크로머시닝 기술을 이용함으로써 10 ㎛두께의 OPS(Oxidized Porous Silicon) 에어 브리지를 제조하고, 그 위에 전송선로를 형성하여 그 RF 특성을 조사하였다. OPS 에어 브리지 위에 형성된 CPW(Coplanar Waveguide)의 손실이 OPSL 위에 형성된 전송선의 삽입손실보다 약 2 dB 정도 적은 것을 보여주었으며, 반사손실은 OPSL 위에 형성된 전송선의 반사손실보다 적으며 약 -20 dB를 넘지 않고 있다. 본 연구에서 개발한 산화된 다공질실리콘 멤브레인 및 에어 브리지 구조는 CMOS 공정 후에 사용 가능하며, 초고주파 회로 설계시 편리성과 유용성을 제시하고 있다. This paper proposes a 10 ㎛ thick oxide air-bridge structure which can be used as a substrate for RF circuits. The structure was fabricated by anodic reaction, complex oxidation and micromachining technology using TMAH etching. High quality films were obtained by combining low temperature thermal oxidation (500 ℃,1 hr at H_2O/O_2) and rapid thermal oxidation (RTO) process (1050 ℃, 2min). This structure is mechanically stable because of thick oxide layer up to 10 ㎛ and is expected to solve the problem of high dielectric loss of silicon substrate in RF region. The properties of the transmission line formed on the oxidized porous silicon (OPS) air-bridge were investigated and compared with those of the transmission line formed on the OPS layers. The insertion loss of coplanar waveguide (CPW) on OPS air-bridge was (about 2 dB) lower than that of CPW on OPS layers. Also, the return loss of CPW on OPS air-bridge was less than about - 20 dB at measured frequency region for 2.2 mm. Therefore, this technology is very promising for extending the use of CMOS circuitry to higher RF frequencies.

To obtain the fundamental information for the successful breeding of rice protein, using various mutant lines derived from several varieties, the experiments were conducted on the nitrogen content of leaf and protein content of grain, content of protein fraction, screening method and other related works. Protein content of grain in mutant lines was not associated with nitrogen content of leaf. Accumulation pattern of protein and protein fractions of high protein mutant lines from heading to maturity was similar to that of existing varieties. In various mutant lines glutelin fraction accounts for more than 60% or protein. In high protein mutant lines with various grain weight and shape, positive correlation of their protein content and grain weight, grain weight and grain length, and grain length and protein content were found. Although the correlation coefficients between biuret and Kjeldahl method were found to be significant, diagram for the relation of absorbance of colorimetric method and protein percent by Kjeldahl in various mutants was scattered.

Intentional replantation of the posterior teeth has been performed as a last resort except extraction when it is impossible to perform the conventional endodontic or surgical endodontic treatment. Many studies have done with the prognosis, and root resorption, of which the responsibility might have been injury of periodontal ligament and remaining periodontal lesion, proved to be major cause of failure. Intentional replantation, however, can exclude anatomic difficulty, risk of nerve injury, and maxillary sinus trauma that surgical access can raise, especially in posterior teeth, and it is reported that success rate is not less than surgical endodontics, independent of replantation of traumatically avulsed teeth. The success of intentional replantation can be evaluated with, clinically, ruduction of pocket depth, pain and mobility(physical mobility), and, radiographically, hard tissue formation, reduction of periapical radiolucency. In this case report, for the maxillary left first bicuspid with dens evaginatus that had periapical lesion, painfulness, mobility and showed no reduction of mobility after even extirpation and a number of irrigation, extraction followed by extraoral root filling with calcium hydroxide and replantation was performed. Based on many studies, it is concluded that hard tissue formation capacity of calcium hydroxide, preceded exterpation before extraction, and careful extraction without injuring periodontal ligament affected successful results of this case.

The purpose of this study is to examine chemical characteristics of groundwater for granitic and andesitic rocks in the vicinity of Mt. Geumjung, Pusan city, to establish the possible hydrogeochemical model of groundwater, and to evaluate the potential of groundwater pollution. According to the Piper diagram, groundwater in the study area mostly belongs to Ca^2^+-HCO_3 and Na^+-HCO_3 types. High concentration of Ca^2^- and Na^+ in groundwater are ascribed to the dissolution of plagioclase. Statistical methods (correlation analysis and factor analysis) were introduced to make the interpretation of analyzed data. Factor 1, consisting of pH, EC, Na^+, K^+, NH_4^+, Cl^- SO_4^2 and NO_3^-, explains the: effects of water-rock interaction such as dissolution of plagioclase and mica, and the influence of anthropogenic sources (domestic and industrial wastes). Factor 2, consisting of SiO_2, Ca^2^+ and HCO_3^- explains the dissolution of Ca-plagioclase. A hydrogeochemical modeling code, PHREEQC identifies and quantifies water-mineral reaction in fissures of the bedrock. The result of the modeling indicates the dissolution of major elements and formation of the kaolinite mineral.

TSIC(Thermally stimulated ionic current) method, based on the repeated measurements with various heating rates, has been used to investigate the kinetic behavior of mobile ions in the SiO₂layers of an Al-SiO₂-Si system. Experimental results have shown two current peaks at the temperature ranges of 80℃-120℃(A peak) and 400℃-450℃(B peak) respectively, which are caused by the release of Na+ ions and K+ ions trapped at the Al-SiO₂ interface and the Si-SiO₂ interface respectively, in a MOS structure. From the results, activation energies (E), attempt-to-escape frequencies (S) and the initial number of trapped ions(n。)are evaluated for each group by the various heating rate method. According to the values of E.S and n。, it is found that deeper traps are distributed in the Si-SiO₂ interface and that K+ions are trapped in deeper trap than Na+ ions. It is also found that the magnitude of the current peaks is increased while the tempratures showing those peaks are decreased, as the gate voltage is increased.
