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.

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.

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.

본 연구는 경주지역 1개 고등학교 3학년 여고생을 대상으로 초경 시작 전인 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레 수치와 초경 연령을 파악하여 여성의 초경이 빠를수록 체성장 속도의 변화가 있을 것이라는 가설을 기초로 두 요인간의 관련성을 파악하고자 시행되었다. 경주시 1개 여자고등학교 3학년생 총 317명에 대해 ㅊ경 나이, 초경시 심리 상태, 초경이 시작되었을 때의 상담 여부와 상담하였던 사람, 부모 신장과 초경전후의 식사 규칙성, 다이어트 경험, 수면시간, 스트레스, 음주/흡연 여부, 질병력 등에 대한 설문 조사를 시행하였고, 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레에 대한 정보는 건강기록부에서 확보하였다. 상기 대상자 중 건강기록부가 분실된 39명, 초경나이에 대해 응답하지 않았던 29명 및 결석 등으로 조사를 하지 못하였던 42명을 제외한 조사 대상자는 206명으로 선정하였다. 대상자들의 초경연령 평균값(Mean±SD)은 13.0±1.11이었고, 초등학교 4학년부터 고등학교 2학년까지의 초경 이후 신장 성장률은 감소하였으며, 초경연령이 빠른 군이 초등학교 때는 신장에 있어서 우위를 차지하나 고등학교에 오면서 신장은 비슷한 수준이 되었다. 초경후 1-2년 사이에 체중과 흉위의 증가율은 감소하였고, 초경연령이 빠른 군이 초등학교와 고등학교 사이에 체중과 흉위에서 모두 우위를 차지하였다. 본 연구의 결과는, 흔히 이차 성징의 시작 시점 혹은 사춘기의 시작 시점으로 보고있는 초경 연령이 청소년기의 성장과 밀접한 관련성이 있고, 특히 체중과 흉위의 성장 속도와 밀접한 관련성이 있음을 시사한다. To understand the onset of menarche in relation to changes in physical growth that take place during female adolescence, especially the changes in height and weight velocity. The 207 senior in one women high school of Kyongju were investigated in April 3 to 8, 2001. We collected the information, relation in the age at menarche, height & weight of parents, regularity of eating, and obesity diet, duration of sleeping, sickness & stress near age at menarche, by self-recording. The status of height, weight & chest circumference between the 4th grade of primary school and the junior of high school was collected by individual Health Record. The results were followed; The average age at menarche was 12.95±1.11 years old and the most frequent age of menarche is 13 years. After menarche, the velocity of height, weight and chest circumference were decreased. The most rapid group of menarche hold dominant position in height during elementary school. As time passed, they dont hold dominant position in height. The most rapid group of menarche get an advantage in the weight and the girth of chest after elementary school. The height of subjects is directly proportional to the height of their parents. These results suggest that the starting age at menestuation can be closely associated with physical growth and development.
