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

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.

Four strains of Drosophila melanogaster : one wild strain gathered from the native inhabitant group on Ssangchon-dong in Kwangju, Korea, from May 10 to 23, 1988 and three strains bred and kept in incubators of Kwangju Teachers college for many years-namely, Oregon-R, cinnarbar brown and SD-72 were taken for this experiment to find the effects of two medicines are so constitued Diethylstilbestrol, Euvestrol, and Stilbestrol (Jungwon pharm. Co.) respectively, on the development and eclosion of Drosophila melanogaster. Eggs and imagines of these strains were given Euvestrol and Stilbestrol, and bred in incubators separately, and the following results were obtained from observation. When the laid eggs of Drosophila melanogaster were given Euvestrol Inj., no difference was found by strains, but there was difference by quantity of medicines given. When the imagines of Drosophila melanogaster were given Euvestrol Inj., no difference was observed by strains, but some difference by concentration of medicines with serious effect in high concentration. When the laid eggs of Drosophila melanogaster were given Stilvestrol tab., difference of effects was observed neither of strains by quantity of medicines. When the imagines of Drosophila melanogaster given Stilbestrol tab., showed little difference of effects among the four strains, and no difference by quantity of medicines

Objectives : Major depressive disorder (MDD) causes patients' distress and makes socioeconomic burden, both directly and indirectly. We used the concept of lost productive time (LPT) to estimate the indirect costs and calculated both absenteeism and presenteeism among workers with MDD. Mcthods : Depression group was recruited from workers visiting psychiatric outpatient clinic who had MDD without major physical or mental disorders (N= 106). Age and sex matched healthy control group was also recruited through advertisement (M=100). All participants completed a interview using WHO Health and Work Performance Questionnaire (HPQ), Job Stress Measurement Scale for Korean Employees, and Hamilton Rating Scale for Depression. Statistical analysis was performed with independent t-test or χ² test as characteristics of values (p=0.05). Results : The number of absence (0.94-day/month vs. 0.10-day/month, P=0.015) andthe numberofearly leaving (2.56-day/month vs. 0.24-day/month, P<0.001) were significantly higher in the depression group. Depression group evaluated their Perfor-mance level much lower than controls with significant value (5.16 vs. 7.62, P<0.001). In addition, depression group estimated their performance level during the last 4 weeks lower compared to the level of past 1-year (5.16 vs 6.63, P<0.001). The estimated costs of absenteeism in depression group were higher than controls by 2,520,000 Korean Won per year, and those of presenteeism were also higher by 4,880,000 Korean Won per year. The total costs of LPT in depression group were higher than controls by 7,400,000 Korean Won, which corresponds to 26% ofmean annual salary. In addition, the level of occupational stress, such as high demand and interpersonal conflict, was higher in the depression group. Conclusion : Major depressive disorder costs substantial productivity loss to workers and their company. Presenteeism imposes more time cost than absenteeism. Effectiveness trials are needed to devise cost-effective programs for the early detection and treatment of depression at the workplace.

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.
